As well known, with reference to
With reference to
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional engage block for a tool seat of a rotary tool turret.
The main objective of the present invention is to provide an improved engage block for a tool seat of a rotary tool turret, which can be easily detached from the rotary tool turret by an elongate tool.
To achieve the objective, the engage device in accordance with the present invention comprises an engage block mounted into the rotary tool turret for positioning the tool seat. A bolt extends through the engage block and is screwed into the rotary tool turret for holding the engage block in place and making the engage block securely abutting the tool seat. A locking member is mounted to the engage block to prevent the bolt from detaching from the engage block.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

With reference to
The engage block (20) includes a through hole (200) eccentrically defined therein. The through hole (200) is divided into a first section (21) and a second section (22), wherein the first section (21) has a diameter grater than that of the second section (22) such that a shoulder (221) is formed between the first section (21) and the second section (22). The first section (21) has a threaded portion (211) formed on an inner periphery thereof near an opening of the through hole (200). An inclined engage portion (24) is formed on an outer periphery of the engage block (20) and corresponds to the second section (22) of the through hole (200).
The bolt (30) has a head (31) and a threaded rod (32) centrally and longitudinally extending from the head (31), wherein the head (31) abuts against the shoulder (221) and the threaded rod (32) extending through the second section (22) of the through hole (200). As a result, the bolt (30) is rotatable relative to the engage block (20). The head (31) has a polygonal hole (311) centrally and longitudinally defined therein.
The locking member (40) is formed with a threaded outer periphery (41) that is screwed onto the threaded portion (211) of the first section (21). The locking member (40) has a threaded polygonal hole (43) defined therein and extending therethrough, wherein the distance between two opposite sides of the polygonal hole (43) in the locking member (40) is greater than a length of a diagonal of the polygonal hole (311) in the head (31) of the bolt (30).
When mounting the engage device to the rotary tool turret (10) to secure the tool seat (11), the engage block (20) with the bolt (30) and the locking member (40) is put into the second hole (13) and make the engage portion (24) of the engage block (20) corresponding to that of the tool seat (11). A wrench (70) extends through the threaded polygonal hole (43) and into the polygonal hole (311) such that the engage block (20) is gradually moved toward a bottom of the second hole (13) to make the two engage portions (111, 24) securely abutting each other for holding the tool seat (11) in place when the bolt (30) is rotated relative to the engage block (20) and threaded rod (32) is screwed into the threaded hole (131) in the rotary tool turret (10).
When the replacing the tool seat (11), the operator only needs to lose the bolt (30) to make the engage portion (24) of the engage block (20) away from the engage portion (111) of the tool seat (11). Then, the operator can easily detach tool seat (11) from the rotary tool turret (10).
When disassembling the engage device in accordance with the present invention, the wrench (70) passes through the threaded polygonal hole (43) in the locking member (40) and is engaged into the polygonal hole (311) in the blot (30). The operator can loose the bolt (30) by rotating the wrench (70) to make the threaded rod (32) of the bolt (30) completely separated from the threaded hole (131) in the rotary tool turret (10). Finally, an elongate tool (60), including a threaded rod (61) longitudinally extending therefrom, is inserted into the second hole (13) and the threaded rod (61) is screwed into the threaded polygonal hole (43). Then, the operator can pull the engage block (20) with the bolt (30) and the locking member (40) by the elongate tool (60) that is longitudinally connected to the locking member (40).
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
