Abstract
Description
Technical Field
[0001] This application relates to the field of machining technology, and more specifically, to a clamping mechanism and hardware processing equipment. Background Technology
[0002] In the processing of hardware parts, clamping mechanisms are often used to clamp and fix the hardware parts first, and then other tools are used to cut, weld, grind and process the hardware parts. However, the hardware parts have different contours, and traditional clamping blocks cannot fit the hardware parts over a large area, resulting in insufficient clamping stability.
[0003] In response, Chinese patent application number CN202321000881.8 discloses a hardware clamping mechanism. This solution mainly involves two jaws clamping the hardware close to each other. Furthermore, depending on the specific shape of the hardware, the internal hexagon head can be rotated so that the end of the screw abuts against the surface of the hardware. The end face of the screw is smaller than the clamping face of the jaws, which can perform a second clamping on hardware with irregular surfaces, further clamping and fixing the hardware, making the clamping and fixing of the hardware more secure and stable.
[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:
[0005] Multiple screws are needed for reinforcement, and each screw needs to be operated individually, which is quite troublesome. Utility Model Content
[0006] To overcome the above deficiencies, this application provides a clamping mechanism and a hardware processing equipment, which aims to improve the problems mentioned in the background art.
[0007] In a first aspect, embodiments of this application provide a clamping mechanism, including a base and a driving member. A clamping block is slidably connected to the base, and the driving member drives the two clamping blocks to open and close. A groove is provided on the clamping surface of the clamping block, and an elastic body is provided in the groove.
[0008] In one specific implementation, the driving component includes a rocker arm and a connecting rod. The rocker arm is rotatably connected to the base, and a connecting rod is hinged to each end of the rocker arm. The other end of the connecting rod is hinged to the corresponding clamping block.
[0009] In one specific implementation, the drive unit further includes a motor, which is mounted on the base and its output end is fixedly connected to the rocker arm.
[0010] In the above process, the motor drives the rocker arm to rotate, and the two connecting rods drive the two clamping blocks to open and close, thereby realizing the clamping action.
[0011] In one specific implementation, the grooved surface of the clamping block is fitted with a rubber pad.
[0012] In the above process, the rubber pad is used to protect the elastomer and the clamping block. It can protect the elastomer and reduce damage to the elastomer. It can also protect the hardware from damage to the clamping block. After the rubber pad is worn, it is easy to maintain. On the other hand, when clamped, the hardware is trapped in the elastomer. When released, the hardware may pull the elastomer out. Therefore, the rubber pad can play a role in fixing the elastomer.
[0013] In one specific implementation, a sleeve is longitudinally inserted into the back of the clamping block, and the sleeve is longitudinally inserted into the rubber pad.
[0014] In the above process, the rubber pad is first clipped onto the clamping block, and then the sleeve is inserted vertically downwards into the clamping block and the rubber pad to fix the rubber pad. The rubber pad, the clamping block and the clamping block are all provided with corresponding grooves to achieve the effect of mortise and tenon connection. It should be noted that the rubber pad has a certain elasticity and is interference fit with the sleeve. The fixing effect can be achieved by the friction between the rubber pad and the sleeve and the clamping block.
[0015] In one specific implementation, the rubber pad is laterally inserted into the clamping block.
[0016] In the above implementation process, the position where the rubber pad and the clamping block are inserted is also provided with a groove. However, in the horizontal insertion, the rubber pad is first inserted horizontally into the clamping block, and then the ferrule is inserted vertically into the rubber pad, which can form a stronger fixing effect on the rubber pad, so that the rubber pad has a fixing effect when it is subjected to resistance in all directions.
[0017] In one specific implementation, an opening is provided above the groove.
[0018] In the above implementation process, the opening above the groove makes it easy to pull out and replace the elastomer at any time. This allows for the selection of an elastomer with appropriate elasticity according to the shape of the hardware. In this embodiment, the elastomer uses its own elasticity and frictional resistance to be inserted into the groove. In another embodiment, a pull head is also fixedly connected to the upper end of the elastomer for easy gripping, so as to pull the elastomer out of the groove.
[0019] Secondly, this application also provides a hardware processing equipment, including the aforementioned clamping mechanism.
[0020] Compared with the prior art, the beneficial effects of this application are: when the clamping block clamps the hardware, the protrusion of the hardware can be inserted into the elastic body in the groove, and the edge of the groove is wrapped and fixed by the clamping block. It has a better clamping effect on hardware with uneven contours, and no additional operation is required. Furthermore, different elastic bodies can be selected and replaced according to the actual situation of the hardware to improve versatility. Attached Figure Description

It should be understood that the following drawings only show some embodiments of this application and should not be regarded as a limitation of the scope.

[0027] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.
[0028] Please see Figures 1-4 This application provides a clamping mechanism, including a base 10 and a drive member 20. Clamping blocks 30 are slidably connected to the base 10. The drive member 20 drives the two clamping blocks 30 to open and close. A groove is provided on the clamping surface of each clamping block 30, and an elastic body 40 is disposed within the groove. When clamping a hardware component, the protruding portion of the hardware component can be inserted into the elastic body 40 within the groove. The edge of the groove is wrapped and secondary fixed by the clamping block 30. This provides a good clamping effect for hardware components with uneven contours, requires no additional operation, and allows for the selection and replacement of elastic bodies 40 with different elasticities according to the actual condition of the hardware component, thereby improving versatility.
[0029] Please see Figures 1-4The driving component 20 includes a rocker arm 21 and connecting rods 22. The rocker arm 21 is rotatably connected to the base 10, and a connecting rod 22 is hinged to each end of the rocker arm 21. The other end of the connecting rod 22 is hinged to a corresponding clamping block 30. The driving component 20 also includes a motor 23, which is mounted on the base 10. The output end of the motor 23 is fixedly connected to the rocker arm 21. The motor 23 drives the rocker arm 21 to rotate, which in turn drives the two clamping blocks 30 to open and close via the two connecting rods 22, thus achieving the clamping action.
[0030] Please see Figures 1-4 The grooved surface of the clamping block 30 is fitted with a rubber pad 50. The rubber pad 50 is used to provide protection for the elastomer 40 and the clamping block 30, protecting the elastomer 40 and reducing damage to it. It also protects the hardware from damage to the clamping block 30. After the rubber pad 50 wears out, it is easy to maintain. On the other hand, when clamping, the hardware is embedded in the elastomer 40. When releasing, the hardware may pull the elastomer 40 out. Therefore, the rubber pad 50 can play a role in fixing the elastomer 40 here.
[0031] Please see Figures 1-4 A retaining sleeve 60 is vertically inserted into the back of the clamping block 30, and the retaining sleeve 60 is vertically inserted into the rubber pad 50. First, the rubber pad 50 is clamped onto the clamping block 30, and then the retaining sleeve 60 is vertically inserted downwards into the clamping block 30 and the rubber pad 50 to fix the rubber pad 50. The rubber pad 50, the retaining block, and the clamping block 30 are all provided with corresponding grooves to achieve the effect of mortise and tenon joint. It should be noted that the rubber pad 50 has a certain degree of elasticity and is interference-fitted with the retaining sleeve 60. The fixing effect is achieved through the friction between the rubber pad 50, the retaining sleeve 60, and the clamping block 30.
[0032] Please see Figures 1-4 The rubber pad 50 and the clamping block 30 are inserted laterally. The insertion position of the rubber pad 50 and the clamping block 30 is also provided with a groove, but it is inserted laterally. The rubber pad 50 is first inserted laterally into the clamping block 30, and then the ferrule 60 is inserted longitudinally into the rubber pad 50, which can form a stronger fixing effect on the rubber pad 50, so that the rubber pad 50 has a fixing effect when subjected to resistance in all directions.
[0033] Please see Figures 1-4 An opening is provided at the top of the groove. The opening at the top of the groove facilitates the easy removal and replacement of the elastomer 40. This allows for the selection of an elastomer 40 with appropriate elasticity based on the shape of the hardware. In this embodiment, the elastomer 40 is inserted into the groove using its own elasticity and frictional resistance. In another embodiment, a pull head is fixedly connected to the upper end of the elastomer 40 for easy gripping, so that the elastomer 40 can be pulled out of the groove.
[0034] Please see Figures 1-4 This application also provides a hardware processing equipment, including the above-mentioned clamping mechanism.
[0035] The working principle of this clamping mechanism is as follows: First, the elastic body 40 is inserted into the clamping block 30, then the rubber pad 50 is clamped onto the clamping block 30, and then the retaining sleeve 60 is inserted vertically downwards into the clamping block 30 and the rubber pad 50 to fix the rubber pad 50. The rubber pad 50 can also hold the elastic body 40 in the groove. A suitable elastic body 40 can be selected according to the shape of the hardware part. The elastic body 40 can be pulled out and replaced at any time. During clamping, the hardware part first compresses the rubber pad 50 and the elastic body 40, causing the hardware part to be recessed close to the clamping block 30. In the case of the rubber pad 50, the edge of the clamping block 30 provides a wrapping and secondary fixation effect, further improving the clamping effect. In summary, when clamping hardware, the protruding part of the hardware can be inserted into the elastic body 40 in the groove, and the edge of the groove is wrapped and secondary fixed by the clamping block 30. It has a good clamping effect on hardware with uneven contours, and no additional operation is required. Furthermore, different elastic bodies 40 can be selected and replaced according to the actual situation of the hardware to improve versatility.
