Description

Technical Field

[0001] This utility model relates to the field of machining technology, and specifically to a linkage-type quick clamping mechanism. Background Technology

[0002] In various industrial production processes, clamping mechanisms are widely used to fix and position workpieces to ensure machining accuracy and operational safety. Traditional clamping mechanisms usually use manual or pneumatic methods for clamping and releasing. These methods may have problems such as low efficiency, uneven clamping force, and complex operation. Especially under the requirements of high precision and high efficiency machining, these limitations of traditional clamping mechanisms are more obvious.

[0003] In addition, existing clamping mechanisms are often not flexible enough in adjusting the clamping force, making it difficult to adapt to workpieces of different materials and sizes. This also limits the application range of clamping mechanisms. In some precision machining fields, higher requirements are placed on the clamping force and stability of clamping mechanisms, and existing technologies often cannot meet these requirements.

[0004] Therefore, it is necessary to develop a new type of linkage-type rapid clamping mechanism that can provide uniform and adjustable clamping force to ensure the stability of the workpiece during processing, while being easy to operate and highly efficient. Utility Model Content

[0005] This invention provides a linkage-type rapid clamping mechanism to solve the problems of the prior art.

[0006] The objective of this utility model can be achieved through the following technical solution: a linkage-type rapid clamping mechanism, comprising:

[0007] A clamping mechanism, comprising a clamping seat and clamping blocks rotatably disposed on both sides of the clamping seat, wherein an assembly groove is provided through the upper end of the clamping seat, the projection of the assembly groove on the horizontal plane is located between the two sets of clamping blocks, and a locking hole is provided through the clamping seat and the clamping blocks.

[0008] The locking mechanism includes a locking device, a brake line slidably disposed on the locking device, and a locking handle rotatably disposed at the end of the locking device. One end of the brake line is fixedly connected to the locking handle, and the other end passes through the locking hole on the clamping seat and the clamping block and is limited by the limiting block.

[0009] In a further improvement, an auxiliary clamping hole is provided through the lower end of the clamping block, and an auxiliary clamping component is provided in the auxiliary clamping hole. The auxiliary clamping component includes a spring disposed in the auxiliary clamping hole and a first adjusting nut threadedly connected to the auxiliary clamping hole. The two ends of the spring abut against the clamping seat and the first adjusting nut, respectively.

[0010] In a further improvement, the clamping seat is provided with a mounting groove, and one end of the spring is disposed in the mounting groove.

[0011] In a further improvement, an adjustment hole is provided through the upper end of the clamping block, and a second adjustment nut is threaded into the adjustment hole.

[0012] In a further improvement, a first rotating hole is provided through the clamping seat, a second rotating hole is provided through the clamping block, and a rotating shaft is inserted between the first rotating hole and the second rotating hole.

[0013] As a further improvement, a locking connector is provided at the upper end of the clamping block, and two sets of locking connectors are provided correspondingly.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In actual use, the user first places the workpiece to be clamped in the assembly slot of the clamping seat. Then, by rotating the locking handle, the brake cable slides and passes through the locking hole on the clamping seat and the clamping block, thereby driving the upper end of the clamping block to rotate towards the workpiece to achieve clamping, ensuring that the workpiece is firmly clamped. The limiting block at the end of the locking handle ensures that the brake cable will not slip out, further enhancing the stability and safety of clamping. The structure is simple and the operation is convenient.

[0016] 2. When the workpiece is placed in the assembly slot, the clamping blocks on both sides initially clamp the workpiece under the action of the spring, preventing the workpiece from shifting before the locking mechanism is activated. At the same time, the compression of the spring can be adjusted by rotating the first adjusting nut, thereby fine-tuning the clamping force of the clamping blocks on the workpiece. When it is necessary to increase the clamping force, the first adjusting nut can be rotated clockwise to further compress the spring, thereby enhancing the clamping force of the clamping blocks on the workpiece. Conversely, rotating the first adjusting nut counterclockwise can reduce the clamping force to adapt to the clamping requirements of workpieces of different materials or sizes, ensuring the stability of the workpiece during processing, and avoiding excessive pressure on the workpiece that could lead to deformation or damage.

[0025] Example 1

[0026] A linkage-type quick clamping mechanism, comprising:

[0027] The clamping mechanism 1 includes a clamping seat 11 and clamping blocks 12 rotatably disposed on both sides of the clamping seat 11. The upper end of the clamping seat 11 is provided with an assembly groove 111. The projection of the assembly groove 111 on the horizontal plane is located between the two sets of clamping blocks 12. The clamping seat 11 and the clamping blocks 12 are provided with locking holes 21.

[0028] The locking mechanism 3 includes a locking device 31, a brake line 32 slidably disposed on the locking device 31, and a locking handle 33 rotatably disposed at the end of the locking device 31. One end of the brake line 32 is fixedly connected to the locking handle 33, and the other end passes through the locking hole 21 on the clamping seat 11 and the clamping block 12 and is limited by the limiting block.

[0029] like Figures 1-4As shown, in actual use, the user first places the workpiece to be clamped in the assembly groove 111 of the clamping seat 11. Then, by rotating the locking handle 33, the brake cable 32 slides and passes through the locking hole 21 on the clamping seat 11 and the clamping block 12, thereby driving the upper end of the clamping block 12 to rotate towards the workpiece to achieve clamping, ensuring that the workpiece is firmly clamped. The limiting block at the end of the locking handle 33 ensures that the brake cable 32 will not slip out, further enhancing the stability and safety of clamping.

[0030] As a further preferred embodiment, the lower end of the clamping block 12 is provided with an auxiliary clamping hole 121, and an auxiliary clamping component 4 is provided in the auxiliary clamping hole 121. The auxiliary clamping component 4 includes a spring 41 disposed in the auxiliary clamping hole 121 and a first adjusting nut 42 threadedly connected to the auxiliary clamping hole 121. The two ends of the spring 41 abut against the clamping seat 11 and the first adjusting nut 42, respectively.

[0031] Specifically, when the workpiece is placed in the assembly slot 111, the clamping blocks 12 on both sides initially clamp the workpiece under the action of the spring 41, preventing the workpiece from shifting before the locking mechanism 3 is pulled. At the same time, the compression of the spring 41 can be adjusted by rotating the first adjusting nut 42, thereby fine-tuning the clamping force of the clamping block 12 on the workpiece. When it is necessary to increase the clamping force, the first adjusting nut 42 can be rotated clockwise to further compress the spring 41, thereby enhancing the clamping force of the clamping block 12 on the workpiece. Conversely, rotating the first adjusting nut 42 counterclockwise can reduce the clamping force to adapt to the clamping requirements of workpieces of different materials or sizes, ensuring the stability of the workpiece during the processing, and avoiding excessive pressure on the workpiece that could lead to deformation or damage.

[0032] As a further preferred embodiment, the clamping seat 11 is provided with a mounting groove 112, and one end of the spring 31 is disposed in the mounting groove 112. The mounting groove 112 is used to limit the movement of the spring 31 and improve the stability of the device.

[0033] As a further preferred embodiment, the upper end of the clamping block 12 is provided with an adjustment hole 122, and the adjustment hole 122 is internally threaded with a second adjustment nut 51. By rotating the second adjustment nut 51, the gap between it and the clamping seat 11 is adjusted, thereby adjusting the opening angle range of the clamping block 12.

[0034] As a further preferred embodiment, the clamping seat 11 is provided with a first rotating hole 113, the clamping block 12 is provided with a second rotating hole 123, and a rotating shaft 52 is inserted between the first rotating hole 113 and the second rotating hole 123.

[0035] As a further preferred embodiment, the upper end of the clamping block 12 is provided with a locking connector 124, and two sets of locking connectors 124 are provided correspondingly to improve the clamping effect.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
