The present invention relates to a power turret, and more particularly to a tool holder on which a tool holder is attached by a pressing mechanism.

Referring to the sixth figure, the general power turret 900 is provided with a plurality of mounting holes 91 in the turret body 90 for placing various machining tools to assist the cutting process. Each of the mounting holes 91 can respectively provide a toothed portion 95. The power tool holder 96 is mounted, and the outer circumference of the turret body 90 is correspondingly disposed with a fixing hole 92 corresponding to the mounting hole 91 corresponding to each of the mounting holes 91. The fixing hole 92 is inserted with a latching tooth. The pressing block 93 of the portion 94. As shown in the seventh figure, the pressing block 93 defines a stepped through hole 97 for a locking bolt 98 to pass through. The locking bolt 98 is locked in a screw hole 99 at the bottom of the fixing hole 92, forcing the engaging portion 94 of the pressing block 93 and the engaging portion 95 of the power tool holder 96 to be engaged with each other. The power tool holder 96 is fixed in the mounting hole 91 of the turret body 90 to prevent detachment for power output to achieve the purpose of cutting.

When the conventional pressing block 93 is to be mounted on the turret body 90, the pressing block 93 is first inserted into the fixing hole 92 of the turret body 90, and the locking bolt 98 therein is screwed into the fixing hole 98. The screw hole 99 of the fixing hole 92 is forcing the engaging portion 94 of the pressing block 93 to mesh with the engaging portion 95 of the power tool holder 96; however, the locking bolt 98 is screwed into the fixing hole 92. In the process of the screw hole 99, the locking bolt 98 is often over-tightened or strongly forced, resulting in the pressing block 93 which has no rotational kinetic energy, and a shoulder 970 in the stepped through hole 97. Between the screw head 980 of the locking bolt 98 and the screw head 980 of the locking bolt 98, the rotational kinetic energy is generated by the frictional engagement, so that the engaging portion 94 of the pressing block 93 and the engaging portion 95 of the power tool holder 96 are misaligned. Deviating from the normal occlusal surface, as indicated by the broken line in the eighth figure, in severe cases, the engaging portion 94 of the pressing block 93 and the engaging portion 95 of the power tool holder 96 may be deformed due to improper occlusion, resulting in the locking bolt. 98 is unsatisfactory during the process of unscrewing the fixing hole 92, and may not normally drive the pressing block 93 out of the fixing hole 92.

In order to overcome the above disadvantages, the present invention provides a power turret, the knife seat pressing mechanism has a safety mechanism, which ensures that the power tool seat can be normally engaged with the pressing block and is firmly fixed during installation, completely solving the pressing block. The problem of rotational kinetic energy is generated when the locking bolt is forced.

For the purpose of the prior art, the power turret of the present invention comprises a turret body, a power tool seat inserted in the turret body and mounted for the tool, and a knife for fixing the power tool block to the turret body. a clamping mechanism and a clamping member for preventing a pressing block on the blade fastening mechanism from rotating.

Specifically, the turret body has a mounting hole, a fixing hole and a positioning hole respectively corresponding to the power tool seat, the tool holder pressing mechanism and the Card parts. The mounting hole and the positioning hole are each in communication with the fixing hole. The power tool holder has a post for mounting the mounting hole of the turret body. The clamping member is disposed on the positioning hole of the turret body. The knife base pressing mechanism comprises the above-mentioned pressing block and a locking bolt. The pressing block has a cylindrical shape and is disposed on the fixing hole of the turret body, and an inclined surface is formed at one side thereof, and the inclined surface is provided with a latching portion corresponding to a latching tooth of the power tool seat unit. The locking bolt is disposed through a longitudinal stepped hole of the pressing block to force the engaging portion of the pressing block to engage with the engaging portion of the power tool seat.

In addition, the outer side of the pressing block further defines a positioning slot that communicates with the positioning hole of the turret body and correspondingly receives one end of the clamping member to prevent the pressing block from being fixed in the turret body. Rotating relative to the turret body. Thereby, the pressing block cannot rotate along with the locking bolt even when the locking bolt is tightened, thereby preventing the improper engagement of the pressing block and the power tool seat.

Other objects, features, and details of the present invention will be apparent from the description and appended claims.
