In the figure: 1. a claw disk; 2. a chute; 3. a clamping cylinder; 4. a clamping jaw; 5. a pin slot; 6. a limit groove; 7. a connecting block; 8. a clamping block; 9. rubber blocks.
Detailed Description
The utility model will now be further described by way of specific examples with reference to the accompanying drawings, which are given by way of illustration only and not by way of limitation.
Referring to fig. 1-4, the present utility model provides a technical solution: the utility model provides a three claw hydraulic pressure clamp frock of removable jack catch, the quantity of spout seting up is three, and adopts triangle-shaped design between the three spout for this device adopts three claw designs.
The number of the clamping cylinders is three, the clamping cylinders and the sliding grooves are in one-to-one correspondence, and the clamping cylinders can generate driving force to drive the clamping jaws to move.
The rear surface of the clamping jaw contacts with the claw disc, and the clamping jaw and the sliding groove are in one-to-one correspondence, so that the clamping jaw can be pushed.
The limiting groove and the pin groove are designed integrally, and an intercommunication type design is adopted between the limiting groove and the pin groove, so that the clamping block can be clamped into the limiting groove.
The clamping block is fixedly connected with the connecting block, so that the clamping block cannot loosen.
One side of two screens piece are opposite to each other extends to the inside of two spacing grooves respectively, screens piece and spacing groove joint, can be connected clamping jaw and connecting block.
One end fixedly connected with rubber block that clamping cylinder was kept away from to the clamping jaw for can not cause the mar when the centre gripping object.
Working principle: when the user needs to replace the clamping jaw 4, the user pulls the clamping jaw 4 upwards, so that the limiting groove 6 in the pin groove 5 on the clamping jaw 4 is separated from the clamping block 8 on the connecting block 7, and therefore limiting of the clamping jaw 4 is completed, and the clamping jaw 4 is detached for replacement.
The working process can be known as follows:
this three-jaw hydraulic pressure clamp fixture of removable jack catch through setting up keyway 5, spacing groove 6, connecting block 7 and screens piece 8 for this device has the function of convenient change when using, lets the user only need upwards pulling just can accomplish the change when changing clamping jaw 4, reduces the time that the user spent, brings the facility for the user, thereby has improved the practicality of this device, has satisfied the user demand of user.
