Description

Oil-pressed claws with markings

technical field

The utility model relates to an oil pressure claw used for lathe chucks, more precisely, relates to an invention in the aspect of a marked oil pressure claw that can be quickly positioned and installed.

Background technique

Please refer to the prior art Fig. 4, which is a partial exploded perspective view of the hydraulic claw installed on the hydraulic chuck. As shown in the figure, an hydraulic chuck 20 is provided with three diameters at equal intervals on the periphery of the top surface of the hydraulic chuck 20. To the sliding groove 21, and each sliding groove 21 is provided with a sliding seat 22 that can move toward the axis, and each sliding seat 22 is concavely provided with a radial ℒ-shaped groove 23, and on the top Two radial positioning teeth parts 24 are arranged in parallel on the surface at equal intervals, and a ㄒ-shaped seat 25 is arranged in the ㄒ-shaped groove 23, wherein the top surface of each sliding seat 22 is combined with an oil pressure claw 30; each oil pressure claw 30 Elongated block, and form a pushing surface 31 at the front end, the pushing surface 31 can be cut into different shapes, so as to be suitable for clamping different workpiece surfaces, and each hydraulic claw 30 is respectively provided with a bottom surface on both sides The row corresponds to the toothed portion 32 of the positioning toothed portion 24, and two positioning holes 33 are vertically pierced on the top, and two bolts 40 are used to pass through the two positioning holes 33 and screw into the ㄒ-shaped block 25, and each oil pressure claw 30 is fixedly combined in the The top surface of each sliding seat 22.

Since the hydraulic chuck moves the stroke of the hydraulic claws according to the shape of the pushing surface of the hydraulic claws, when the same set of hydraulic claws is used for workpieces of different sizes, there may be insufficient strokes or inconsistent shapes, resulting in failure Due to the occurrence of clamping, it is necessary to install different types of hydraulic jaws and adjust the positioning position to match the stroke of the hydraulic chuck when processing different workpieces. Therefore, it is often necessary to disassemble and exchange different hydraulic jaws to adapt to the workpiece. However, the position of the same set of hydraulic claws will be different from the previous one after each disassembly, so it is necessary to re-calibrate the position of each hydraulic claw relative to the sliding seat so that the position of the clamping workpiece is correct. But it takes a lot of time to make corrections in this way, which is very troublesome.

In addition, some people correct the position by memorizing a certain tooth of the tooth part of the oil pressure claw to align with a certain tooth of the tooth part, so that when the oil pressure claw is reinstalled, the oil pressure claw can be correctly installed on the sliding seat. In terms of position, however, this method needs to turn over the oil pressure claws to see the alignment, so the operation is still too troublesome, and there are too many teeth on the toothing part and the positioning toothing part, and one number is really a waste of time.

This shows that above-mentioned existing oil pressure raw claw also has deficiency, and Cheng waits to be improved.

In view of the defects of the existing hydraulic claws mentioned above, the designer has been engaged in the design and manufacture of such products for many years, has accumulated rich practical experience and professional knowledge, and actively researched and innovated, in order to create an improved molding structure.
