The present invention relates to a vise, and more particularly to a vise with an adjustable operating angle.
A conventional vise has a fixed seat such that a wedge washer is provided under the workpiece such that the workpiece is inclined relative to the fixed seat when the workpiece needs to be processed at a specific angle. However, the standards of the wedge washer are limited such that the main shaft of the processing machine also needs to be adjusted. It is inconvenient to the conventional vise when the workpiece needs to be processed at a specific angle.
In view of this, some vises with an adjustable operating angle are on the market for adjusting the operating angle of the workpiece by the structures of the vise. The conventional vises have two adjusting types including swing left and right relative to two opposite sides and swing back and forth relative to two opposite ends. As well known, a distance between two opposite ends of the vise is greater than that between the two opposite sides of the vise. As a result, the vise, in the type of swing back and forth, has a greater adjusting range and the adjusting range may intervene the operating room of the processing machine.
The main objective of the present invention is to provide an improved vise that has an adjustable operating angle.
To achieve the objective, the vise with an adjustable operating angle in accordance with the present invention comprises a base member formed with a bottom and a top surface. A front pier and a rear pier are respectively formed on a front end and a rear end of the top surface of the base member. Each of the front pier and the rear pier is formed with a contact surface. Each of the two contact surfaces has a semicircular groove defined therein. A flange is formed on a bottom of each of the two semicircular grooves. A rotary seat is mounted onto the front pier and the rear pier. The rotary seat includes a platform, a fixed jaw, a movable jaw, a lead screw and a power brake, wherein the platform is pivoted to the front pier and the rear pier. The fixed jaw is secured on a rear end of the platform and the movable jaw is movably mounted onto the platform. The lead screw is rotatably mounted in the platform for driving the movable jaw and making the movable jaw reciprocally moved relative to the platform. The power brake is disposed on a front end of the lead screw and extends through the front pier. The power brake includes power force elements disposed therein for enhancing a clamping effect of the fixed jaw and the movable jaw and providing an anti-loose function. A front turntable and a rear turntable are respectively secured on a front end and the rear end of the platform. Each of the front turntable and the rear turntable is a circular structure and co-axially corresponding to the lead screw. The front turntable and rear turntable respectively has a bottom half selectively rotatably received in the semicircular groove of a corresponding one of the front pier and the rear pier. The flange of the front pier and the flange of the rear pier respectively inwardly and movably abut against the front turntable and the rear turntable. The front turntable has a through hole co-axially defined therein, wherein the front end of the lead screw extends through the through hole in the front turntable. A front fastening seat and a rear fastening seat are respectively mounted onto the front pier and the rear pier. The front fastening seat and the rear fastening seat respectively includes a contact surface formed on a bottom of each of the front fastening seat and the rear fastening seat, wherein the contact surface of the front fastening seat abuts the contact surface of the front pier and the contact surface of the rear fastening seat abuts the contact surface of the rear pier. The contact surfaces of each of the front fastening and the rear fastening seat has a semicircular groove defined therein. A flange is formed on a bottom of each of the two semicircular grooves of the front fastening seat and the rear fastening seat. The front turntable has an upper half selectively rotatably received in the semicircular groove in the front fastening seat and the rear turntable has an upper half selectively rotatably received in the semicircular groove in the rear fastening seat. Multiple fastening members are provided to control a loose/tight condition between the front fastening seat/rear fastening seat and the front pier/rear pier. In the preferred embodiment of the present invention, the multiple fastening members are multiple bolts. At least two threaded holes are defined in the contact surface of each of the front pier and the rear pier. At least two through holes 705/805 are defined in the contact surface of each of the front fastening seat and the rear fastening seat, wherein each through hole in the front fastening seat aligns with a corresponding one of the at least two threaded holes in the front pier and each through hole in the rear fastening seat aligns with a corresponding one of the at least two threaded hole in the rear pier. Each fastening member extends through a corresponding one of the through holes in each of the front fastening seat and the rear fastening seat, and is tightly screwed into a corresponding one of the threaded hole in each of the front pier and the rear pier such that the front pier and the front fastening seat tightly clamp the front turn table, and the rear pier and the rear fastening seat tightly clamp the rear turntable. On the contrary, when all the fastening members is loosed, the front pier and the front fastening seat release the front turn table, and the rear pier and the rear fastening seat release the rear turntable such that the rotary seat is rotatable relative to the base member and the operating angle of the rotary seat is adjusted relative to the base member.
