Description

Quickly change the claws of the claws

The present invention relates to a raw claw, and more particularly to a raw claw that can quickly change the claw.

The raw claw is a member that is mounted on the chuck for holding the workpiece. Since the workpiece has a plurality of different shapes, the raw claw also has a corresponding shape to fit the clamping. In the job site, after processing a batch of workpieces, if the next batch of workpieces to be processed has different shapes, the original claws must be removed from the chuck and replaced with the next batch. The claws of the workpiece shape can continue the machining operation.

However, the conventional claws are bolted to the chuck, so when the claws are replaced, the bolts must be loosened and removed before the claws can be removed from the chuck. Then, when the next type of raw claw is to be installed, the relative position between the raw claw and the chuck is first positioned, and after the positioning is completed, the bolt is tightened to lock the raw claw on the chuck. Therefore, the action of replacing the raw claws is quite time-consuming and laborious, and the number of the raw claws required for clamping the workpiece is usually plural, that is, the aforementioned actions need to be repeatedly performed a plurality of times, thereby correspondingly in terms of time and effort. Multiplied several times.

Therefore, the object of the present invention is to provide a claw that can quickly change the claws.

Therefore, the quick-changeable claw of the present invention is suitable for being radially mounted on the forming disc along one of the forming discs, and includes a seat body detachably screwed to the forming disc, and a detachable fastening The body is opposite to the claw body on one side of the forming plate, and the base body includes a first fastening portion, and the claw body includes a second fastening portion that can be engaged with the first fastening portion.

The utility model has the advantages that: when the claw body is detachably fastened to the seat body, and the workpiece of different shapes is required to be clamped, the original claw body is only required to be detached from the seat body. Then, the required claw body is fastened to the seat body to complete the change of the claw, and the seat body is not required to be replaced at the same time during the claw changing process, thereby not only saving the working time of the screw loosening screw, but also eliminating the need for Reposition with the forming disc to achieve fast finger change and save time.

Referring to FIG. 1 to FIG. 3, an embodiment of the present invention is capable of rapidly changing the claws of the claws, and is suitable for being mounted on the forming disk 10 along one of the forming disks 10 in a radial direction, and includes a body 1 and a claw body 2, And a gap 3 between the body 1 and the claw body 2.

The base body 1 is detachably screwed to the forming plate 10, and includes a fastening end face 11 and a card abutting convex surface 12 disposed opposite to the radial direction, a positioning surface 13 facing the forming disk 10, and the opposite The abutting surface 14 is disposed outside the positioning surface 13 and the screw hole 15 is disposed between the positioning surface 13 and the outer abutting surface. The fastening end surface 11 is formed with a first fastening portion 111. The positioning surface 13 is convexly disposed with a positioning rib 131 for positioning on one of the positioning grooves of the forming disk 10. The outer abutment surface 14 is recessed with a recess 141 defining the slit 3. The screw holes 15 are respectively extended by two bolts to lock the seat body 1 to the forming plate 10.

The claw body 2 has a U-shaped cross section and is detachably fastened to one side of the base plate 1 opposite to the forming plate 10, and defines a shape matching the seat body 1 at the U-shaped notch. The space 21 is accommodated. The claw body 2 includes a fastening end wall 22 and a card abutting end wall 23 disposed opposite to each other in the radial direction, and an inner abutting surface 24 abutting against the outer abutting surface 14. The inner wall surface of the fastening end wall 22 defines a second fastening portion 221 that can be fastened to the first fastening portion 111. The inner wall surface of the card abutting wall 23 is recessed with a corresponding abutting groove 231 corresponding to the convex surface 12. It should be noted that, in this embodiment, the slit 3 is defined by the groove 141 of the outer abutting surface 14 and the inner abutting surface 24, but not limited thereto, the slit 3 may also be The outer abutting surface 14 is defined by another groove (not shown) formed on the inner abutting surface 24, or the outer and inner abutting surfaces 14, 24 are each formed with a groove opposite to each other ( The slit 3 is defined by a figure not shown.

Referring to FIG. 4, after the seat body 1 is positioned and locked to the forming plate 10, when the claw body 2 is to be assembled to the seat body 1, the card body 2 of the claw body 2 is inclined to the seat body 1 obliquely. The card is abutted against the convex surface 12, and then the second fastening portion 221 of the claw body 2 is fastened into the seat body 1 by tapping the top surface of the claw body 2 with a hand tool (for example, a hammer). The first fastening portion 111 is configured to fasten and fasten the claw body 2 to the base body 1. It is to be noted that, in the embodiment, the first fastening portion 111 and the second fastening portion 221 are respectively a matching slot and a protruding post, but not limited thereto, the first fastening The portion 111 and the second fastening portion 221 may also be respectively deformed into a matching post and a card slot.

Referring to FIG. 5, when the claw body 2 is to be detached from the seat body 1, it can be carried out by means of a hand tool (for example, a flat-shaped screwdriver) having an end shape fitted to the slit 3, and the end of the hand tool is inserted. After the slit 3, the claw body 2 can be laboriously separated from the seat body 1 by the lever principle.

Referring to FIG. 6, a modification of the embodiment is substantially the same as the embodiment, and the difference from the embodiment is that the variation is applicable to a molding disk using a rod as a positioning mechanism, and the positioning surface 13 is formed with plural numbers. Positioning rods 132 for positioning the shaped discs in a rod-shaped configuration.

Through the above description, the above embodiment has the following advantages, so that the purpose of the present invention can be achieved:

1. The claw body 2 is detachably fastened to the seat body 1. When the claw is changed, the original claw body is only required to be detached from the seat body 1, and the required claw body is fastened to the seat. The body 1 completes the change of the claws, and the seat body 1 does not need to be replaced at the same time during the claw changing process, thereby reducing the time taken for disassembly and installation and accelerating the operation of changing the claws.

2. By the provision of the slit 3, the hand tool can be used to assist in disassembling the claw body 2 fastened to the seat body 1, and the advantage of improving the disassembly convenience is enhanced.

3. By the arrangement of the card abutting convex surface 12 and the card abutting groove 231, the claw body 2 can be installed and disassembled to form a lever point similar to the lever when the seat body 1 is mounted, and the installation and disassembly process can be further improved. In order to save effort, the engagement of the card abutment surface 12 with the card abutment 231 also helps the claw body 2 to be more tightly and firmly fixed to the seat body 1 after installation.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
