Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic clamps, in particular to a hydraulic clamp with a strong clamping effect. Background Art

[0002] A hydraulic clamp is a clamp that uses hydraulic components instead of mechanical parts to achieve automatic positioning, support and clamping of the workpiece through hydraulic control. It is widely used in milling machines, assembly lines, robots and other components. The current hydraulic clamp generally drives the jaws to extend and retract through a hydraulic cylinder, and clamps the workpiece through the retracted jaws. Generally, two jaws are provided, and the two sides of the workpiece are clamped by the two jaws. Although this method can clamp and fix the workpiece, since the clamp only fixes two sides of the workpiece, it cannot clamp and fix the other sides of the workpiece. Therefore, the clamping effect is not stable enough, which makes the clamping stability not good enough, and it is easy to shake when processing the workpiece, which in turn affects the fine processing of the workpiece. There are certain defects and shortcomings, so it needs to be improved. Utility Model Content

By installing a hydraulic cylinder 7 on the top plate 6, the hydraulic cylinder 7 can drive the lifting frame 8 to rise and fall. A connecting seat 9 is provided at the connection between the lifting frame 8 and the slider 10. When the hydraulic cylinder 7 drives the lifting frame 8 to move upward, it can drive the connecting seat 9 and the slider 10 to move upward. Through the limiting relationship between the slider 10 and the inclined frame 11, the inclined frame 11, the telescopic block 3 and the clamping mechanism 4 slide inward, and then the workpiece is clamped by the clamping mechanism 4.

[0028] like Figure 3 As shown, unlike the above-mentioned scheme, the utility model can also realize the telescopic control of the inclined frame 11, the telescopic block 3 and the clamping mechanism 4 by means of a connecting rod 12. A rotating seat 13 is provided at both ends of the connecting rod 12, and the connecting rod 12 is rotatably connected between the slider 10 and the output shaft of the hydraulic cylinder 7 through the rotating seats 13 provided at both ends. When the output shaft of the hydraulic cylinder 7 is extended, the connecting rod 12 rotates to drive the inclined frame 11, the telescopic block 3 and the clamping mechanism 4 to move outward. Conversely, when the output shaft of the hydraulic cylinder 7 is contracted, the connecting rod 12 can be pulled, and the inclined frame 11 is pulled by the connecting rod 12, so that the telescopic block 3 and the clamping mechanism 4 move inward, thereby realizing the clamping and fixation of the workpiece.

[0032] It should be noted that by slidably connecting the slide 406 to the limit groove 404 of the protective frame 401, the slide 406 and the clamp 405 can slide, and the position of the clamp 405 can be adjusted, thereby being able to meet the clamping needs of different types of workpieces, thereby ensuring the versatility of the device.

[0033] like Figure 2 As shown, in some embodiments, a screw rod 402 is rotatably connected to the limiting groove 404 of the protective frame 401, a screw hole adapted to the screw rod 402 is opened at the sliding seat 406 corresponding to the screw rod 402, and one end of the screw rod 402 extends to the outside of the protective frame 401 and is fixed with a handle 403.

[0034] It should be noted that when it is necessary to control the movement of the clamping jaws 405 and the slide 406, the screw rod 402 is rotated by the handle 403, and a screw hole adapted to the screw rod 402 is opened at the slide 406 corresponding to the screw rod 402, so that the slide 406 can slide in the limiting groove 404 of the protective frame 401, thereby realizing the movement control of the clamping jaws 405 and adjusting the distance between the clamping jaws 405 to meet the clamping needs of different workpieces.

[0035] like Figure 2 As shown, in some embodiments, a bearing with clearance fit is provided at the connection between the screw rod 402 and the protective frame 401 to achieve stable rotation of the screw rod 402 .
