[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a positioning and clamping mechanism. Background Technology

[0002] A positioning and clamping mechanism is a mechanical device used to fix and stabilize workpieces, and is widely used in machining, assembly, and inspection. Its main function is to determine the accurate position of the workpiece through positioning elements and to firmly fix the workpiece in that position using a clamping device to prevent displacement or vibration during processing or operation.

[0003] Most existing positioning and clamping mechanisms are composed of a combination of a side clamping cylinder, a lower clamping cylinder, and a cylinder mounting frame. This structural design results in an excessive number of functional power output sources, leading to a large device size. Consequently, the device cannot be used in confined spaces. Furthermore, the design of multiple cylinders increases the difficulty and cost of device maintenance, causing certain inconveniences.

[0004] Therefore, a positioning and clamping mechanism needs to be designed. Utility Model Content

[0005] In order to overcome the shortcomings of existing positioning and clamping mechanisms, which are mostly composed of side clamping cylinders, lower clamping cylinders and cylinder mounting frames, resulting in a large structural volume, making the device unsuitable for use in confined spaces, and increasing the difficulty and cost of device maintenance due to the design of multiple cylinders, the technical problem to be solved by this utility model is to provide a positioning and clamping mechanism.

[0006] The technical implementation scheme of this utility model is: a positioning and clamping mechanism, comprising:

[0007] Mounting plate;

[0011] Optionally, it further includes: a guide member, wherein the guide member is provided on one side of the mounting plate; and a locking pin, wherein the guide member is slidably connected to the locking pin, and the locking pin is fixedly connected to the side pressure member.

[0012] Optionally, it further includes: a side pressure buffer block, wherein the side pressure member is fixedly connected to the side of the side pressure member facing away from the guide member.

[0013] Optionally, it further includes: a first spring, wherein the first spring is disposed on the side pressure member, and the first spring is located on the side of the side pressure member facing the guide member.

[0014] Optionally, it further includes: a height equalizing screw, wherein the height equalizing screw is movably disposed at one end of the pressure swing arm away from the side pressure member; and a pressure buffer block, wherein one end of the height equalizing screw passes through the pressure swing arm and is threadedly connected to the pressure buffer block.

[0015] Optionally, the number of equal-height screws shall not be less than four, in order to improve the smoothness of the movement of the downward pressure buffer block.

[0016] Optionally, it further includes: a second spring, wherein the equalizing screw is provided with the second spring, and the second spring is located between the pressure buffer block and the pressure swing arm.

Detailed Implementation

[0027] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0028] Example: A positioning and clamping mechanism, such as Figures 1-4 As shown, it includes a side pressure member 2, a pivot pin 3, a U-shaped body 6, a mounting plate 7, and a downward pressure swing arm 12. A U-shaped body 6 is provided on one side of the mounting plate 7. A pivot pin 3 is fixedly connected to the U-shaped body 6. The downward pressure swing arm 12 is rotatably connected to the U-shaped body 6 through the pivot pin 3. The side pressure member 2 is movably provided below the U-shaped body 6 and contacts the downward pressure swing arm 12.

[0029] like Figure 4 As shown, a guide 5 is provided on one side of the mounting plate 7. The guide 5 is slidably connected to a locking pin 14, which is fixedly connected to the side pressure member 2. Here, the mounting plate 7 has multiple mounting holes of different sizes. The design of the guide 5 and the locking pin 14 helps the side pressure member 2 to move stably, effectively preventing the side pressure member 2 from shifting during movement and improving the stability of the device.

[0030] like Figures 3-4 As shown, a side pressure buffer block 1 is fixedly connected to the side of the side pressure member 2 facing away from the guide member 5. A height equalizing screw 9 is movably provided at the end of the lower pressure swing arm 12 away from the side pressure member 2. One end of the height equalizing screw 9 passes through the lower pressure swing arm 12 and is threadedly connected to the lower pressure buffer block 11. Here, the design of the side pressure buffer block 1 and the lower pressure buffer block 11 can provide protection for the material during the operation of the device, prevent the device from excessively squeezing the material, and ensure the quality of the material.

[0031] like Figure 3As shown, a second spring 10 is provided on the equalizing screw 9. The second spring 10 is located between the pressure buffer block 11 and the pressure swing arm 12. A first spring 4 is provided on the side pressure member 2. The first spring 4 is located on the side of the side pressure member 2 facing the guide member 5. A groove is provided on the side pressure member 2. The first spring 4 is located in the groove of the side pressure member 2. Here, the first spring 4 and the second spring 10 can flexibly adapt to materials of different thicknesses through their own deformation and recovery characteristics, effectively improving the flexibility and adaptability of the device.

[0032] like Figure 3 As shown, there are no fewer than four equal-height screws 9, which are used to improve the smoothness of the movement of the pressure buffer block 11. Here, the design of multiple equal-height screws 9 helps the pressure buffer block 11 to move stably, effectively preventing the pressure buffer block 11 from shifting during the movement and improving the stability of the device.

[0033] like Figure 3 As shown, a retaining spring block 8 is provided on one side of the mounting plate 7. The retaining spring block 8 is connected to the downward swing arm 12 through a tension spring 13. Here, the tension spring 13 is in a vertical state when it is not under force. When the downward swing arm 12 rotates, the tension spring 13 is stretched by force. When the downward swing arm 12 finishes rotating, the tension spring 13 returns to its original state by its own characteristics and pulls the downward swing arm 12 during the return process, so that the downward swing arm 12 can quickly return to its original state.

[0034] This device is a positioning and clamping mechanism. In use, the mounting plate 7 of the device is installed on the piston rod of the cylinder. When the piston rod of the cylinder extends outward, the side pressure member 2 of the device first contacts the material. Then, the piston rod of the cylinder continues to extend. At this time, the side pressure member 2 moves under the influence of the reaction force, causing the side pressure member 2 to move towards the mounting plate 7 and apply pressure to the lower pressure swing arm 12. This causes the lower pressure swing arm 12 to rotate around the pivot pin 3. The end of the lower pressure swing arm 12 away from the side pressure member 2 deflects towards the material until the lower pressure swing arm 12 contacts the material, thereby realizing the clamping and fixing of the material.

[0035] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
