Description

[Technical field]

[0001] The invention relates to a novel quick clamp. [Background technology]

[0002] In industrial production, many objects need to be clamped and fixed on a workbench during use or processing, such as a mold needs to be clamped and fixed on a machine table during the process of manufacturing a molded object.

[0003] At present, there are two common ways to clamp objects: one is to fix with bolts and nuts, and the other is to fix with hydraulic clamps. For fixing with bolts and nuts, it is necessary to tighten the bolts and nuts manually to force the clamping block so that the clamping block can clamp the object on the workbench. However, manual locking is time-consuming and labor-intensive, and the loading and unloading efficiency is low. In addition, the bolts and nuts may become loose due to insufficient locking force, causing the object to deviate and affect its use or processing. For fixing with hydraulic clamps, it is necessary to use a hydraulic cylinder telescopic rod to push the clamping block to fix the object. Liquid pressure is always required during clamping, but if the pipeline leaks oil, it will cause pressure relief, causing the object to fall, causing damage to the object, and posing a safety hazard. Therefore, the present invention is generated based on the above deficiencies. [Summary of the invention]

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The new quick clamp of the present invention, when it is necessary to clamp an object, the power device drives the force-bearing end of the clamping block, and the clamping end presses the object on the workbench. At this time, the locking device locks the power device so that the force-bearing end remains in a fixed position.

[0020] 4. The new quick clamp of the present invention has a limit end surface arranged on the base for the clamping end to abut against after moving, limiting the maximum stroke so that the force-bearing end of the clamping block can abut against the top support rod to prevent the top support rod from falling out of the hydraulic cavity during the upward movement.

[0021] 5. The new quick clamp of the present invention has a shield on the base which covers the upper side of the force-bearing end of the clamping block to protect the power device and the locking device, so as to prevent debris from falling in and affecting the operation of the power device and the locking device, and also prevent the operator's hands, hair and other parts from accidentally entering, so as to avoid injury to the operator and improve safety.

[0029] The present invention will be further described below in conjunction with the accompanying drawings:

[0030] like Figures 1 to 7 As shown, a new type of quick clamp includes a base 1, a clamping block 2 is hinged on the base 1, and a force-bearing end 21 and a clamping end 22 for pressing an object on a workbench 10 are respectively provided on both sides of a hinge shaft 7 of the clamping block 2. A power device 3 is provided on the base 1, which can drive the force-bearing end 21 to rotate the clamping block 2 around the hinge shaft 4. The base 1 is also provided with a locking device 5 for locking the power device 3 after the clamping end 22 clamps the object so that the power device 3 remains in a fixed position. A resetting device 4 is provided between the clamping end 22 and the base 1, which springs the clamping end 22 to reset the clamping block 2. When it is necessary to clamp an object, the power device 3 drives the force-bearing end 21 of the clamping block 2, and the clamping end 22 presses the object 9 onto the workbench 10. At this time, the locking device 5 locks the power device 3 so that the force-bearing end 21 remains in a fixed position. When the power of the power device 3 fails, such as oil leakage in the pipeline causing pressure relief, the clamping block 2 can always clamp the object 9 to prevent the object from accidentally falling off. The clamping is firm and stable with good safety. When it is necessary to release the object, the locking device 5 unlocks the power device 3, and the power device 3 no longer applies force to the force-bearing end 21. The resetting device 4 presses the clamping end 22 to reset the clamping block 2. The structure is simple and the clamping is convenient.

[0031] The power device 3 is provided with a supporting rod 31 driven by the power device 3 to push the force-bearing end 21 , and the locking device 5 locks the supporting rod 31 so that the supporting rod 31 keeps pressing against the force-bearing end 21 .

[0032] Specifically, Figure 3 As shown, the locking device 5 includes a motor drive assembly 51 and a locking gear 52 driven to rotate by the motor drive assembly 51. The locking gear 52 is connected to the top support rod 31 by threads, and a positioning end surface 11 is provided on the base 1 for the locking gear 52 to press against and position. Through the threaded connection, the locking gear 52 can move up and down along the top support rod 31. When the top support rod 31 presses against the force end 21 of the clamping block 2 to make the clamping block 2 clamp an object, the motor drive assembly 51 drives the locking gear 52 to rotate, and the locking gear 52 moves downward along the top support rod 31. When the lower end surface of the locking gear 52 presses against the positioning end surface 11, the top support rod 31 is locked, and the locking is convenient and quick.

[0033] Specifically, Figure 4As shown, the locking gear 52 is provided with a threaded hole 521, the top support rod 31 is a stud 311 with one end being able to pass through the threaded hole 521, the motor drive assembly 51 comprises a motor 511, a driving gear 513 provided at the power output end of the motor 511, the driving gear 513 is provided with a vertically arranged first spur tooth 5131, and the locking gear 52 is provided with a second spur tooth 522 meshing with the first spur tooth 5131. The motor 511 is also provided with a speed reduction mechanism 512. When the motor 511 is started, the motor shaft of the motor 511 drives the speed reduction mechanism 512 composed of a plurality of multi-stage gears, the speed reduction mechanism 512 drives the driving gear 513 provided at its output end to rotate, the driving gear 513 drives the locking gear 52 to rotate, and then the locking gear 52 can move up and down along the top support rod 31 through threaded connection. Since the driving gear 513 and the locking gear 52 are meshed with each other through the first spur teeth 5131 and the second spur teeth 522 , when the supporting rod 31 moves upward, the locking gear 52 can move along the driving gear 513 with the supporting rod 31 .

[0034] The power device 3 includes a hydraulic chamber 32 disposed on the base 1, a fluid channel 33 connected to the hydraulic chamber 32 and capable of supplying hydraulic fluid to the hydraulic chamber 32, and a support rod 31 disposed in the hydraulic chamber 32 and pushing the support rod 31 upward when the hydraulic fluid enters the hydraulic chamber 32. Specifically, the fluid channel 33 is disposed on the base 1 and one end of the fluid channel 33 can be connected to a fluid delivery pipe. When the hydraulic fluid flows into the hydraulic chamber 32 through the fluid channel 33, the hydraulic fluid pushes the support rod 31 upward, and can then push the force-bearing end 21 of the clamping block 2, so that the clamping end 22 of the clamping block 2 clamps the object on the workbench. In practical applications, the power device 3 can also adopt a pneumatic structure, a mechanical cam structure, or other device that can provide thrust for the support rod 31.

[0035] like Figure 4 and Figure 5 As shown, the base 1 is provided with a limit end surface 12 for abutting against one side of the clamping end 22 to prevent the top support rod 31 from falling out of the hydraulic chamber 32. The limit end surface 12 provided on the base 1 can be abutted against by the clamping end 22 after movement, limiting the maximum stroke, so that the force-bearing end 21 of the clamping block 2 can abut against the top support rod 31, preventing the top support rod 31 from falling out of the hydraulic chamber 32 during the upward movement.

[0036] like Figure 4 As shown, one end of the top support rod 31 extending into the hydraulic cavity 32 is provided with an annular groove 312, and a sealing ring 6 is provided in the annular groove 312. The provision of the sealing ring 6 improves the sealing performance of the hydraulic cavity 32 and prevents the hydraulic fluid from flowing out from between the inner wall of the hydraulic cavity 32 and the outer wall of the top support rod 31.

[0037] The reset device 4 includes a reset spring 41 disposed on the base 1 and a spring cap 42 disposed at the end of the reset spring 41 and capable of pushing the clamping end 22. Specifically, the base 1 is further provided with a mounting hole 15 for mounting the reset spring, and the spring cap 42 always abuts against the clamping end 22 when the clamping end 22 is in a clamped or non-clamped state.

[0038] The base 1 is provided with a shield 8 that covers the force-bearing end 21, the power device 3 and the locking device 5, and the shield 8 is provided with an extension opening 81 for the clamping end 22 to extend and move. The shield 8 can prevent debris from falling in and affecting the operation of the power device 3 and the locking device 5, and also prevent the operator's hands, hair and other parts from accidentally entering, thereby avoiding injuries to the operator and improving safety. The extension opening 81 enables the clamping end 22 of the clamping block 2 to extend out of the shield 8, and the clamping end 22 will not be hindered by the shield 8 when moving.

[0039] like Figure 4 As shown, the base 1 is provided with two oppositely arranged rotating brackets 13, the rotating bracket 13 is provided with a fixing hole 131, the clamping block 2 is provided with a hinge shaft hole 23, and the hinge shaft 7 passes through the fixing hole 131 and the hinge shaft hole 23 to install the clamping block 2 between the two rotating brackets 13. Specifically, the hinge shaft 7 and the fixing hole 131 are interference fit, so that the hinge shaft 7 is immovable relative to the base 1, and the inner diameter of the hinge shaft hole 23 is larger than the outer diameter of the hinge shaft 7, and the clamping block 2 can rotate relative to the base 1.

[0040] like Figure 1 and Figure 2 As shown, the bottom of the base 1 is provided with a mounting portion 14 mounted on the workbench 10. Specifically, the mounting portion 14 is in an inverted T-shape and can be embedded in a T-slot provided on the workbench 10.

[0041] Working principle:

[0042] When an object needs to be clamped, the hydraulic fluid flows into the hydraulic chamber 32 through the fluid channel 33. Figure 6 As shown, the hydraulic fluid pushes the push rod 31 to move upward, and then pushes the force-bearing end 21 of the clamping block 2, so that the clamping block 2 can overcome the elastic force of the return spring 41 and rotate around the rotating shaft 7, and then the clamping end 22 of the clamping block 2 clamps the object 9 on the workbench 10, and then Figure 7 As shown, the motor drive assembly 51 drives the locking gear 52 to rotate, and the locking gear 52 moves downward along the top support rod 31, and when the lower end surface of the locking gear 52 abuts against the support surface 11, the top support rod 31 is locked.

[0043] When the object needs to be released, the motor drive assembly 51 drives the locking gear 52 to rotate in the opposite direction, and the locking gear 52 moves upward along the top support rod 31, and the top support rod 31 is unlocked. At this time, the hydraulic fluid flows out of the hydraulic chamber 32 through the fluid channel 33 to relieve the pressure. Figure 5As shown, the return spring 41 presses the clamping end 22 of the clamping block 2, and at the same time, the supporting rod 31 moves downward under the action of its own gravity and the downward thrust of the force-bearing end 21, so that the clamping end 22 moves upward to release the object 9.
