Description

Technical Field

[0001] The utility model relates to the technical field of metal production, processing and fixing, in particular to a clamping structure for metal processing. Background Art

[0002] Metalworking refers to the production activities of humans processing materials with metallic properties that are composed of metal elements or mainly metal elements. Metalworking can process metal materials into objects, parts and components. The products of metalworking include large parts of bridges and ships, as well as small components of engines, jewelry and watches. It is widely used in different fields such as science, industry, art, handicrafts, etc.

[0003] In the process of metal processing, various clamping tools are often used to fix the metal to support the processing work. Clamping methods include mechanical clamping, adhesive clamping, clamping thread clamps and magnetic clamping. Among them, mechanical clamping is the most common and is most widely used in the metal processing process. Mechanical clamping usually uses thread clamps, chucks, elastic clamps and other mechanisms to clamp the tool on the spindle. The advantages of mechanical clamping are large clamping force, good stability, and simple and convenient operation. Mechanical clamping is suitable for most conventional processing occasions, especially for high-precision processing occasions.

[0004] The patent document with publication number CN219945920U discloses a clamping structure for thin metal processing, which is provided by a first clamping mechanism and a second clamping mechanism. Under the operation of a double-headed motor, the two gears drive the four L-shaped rack plates to move closer to each other, and at the same time, the two groups of first telescopic rods are stretched to facilitate the stable movement of the two L-shaped plates, and the cooperation of the two groups of second telescopic rods, springs and buffer pads can play a better buffering and protective effect during horizontal clamping. After the operation of the two driving motors, the two pressure plates are moved downward, and the two groups of third telescopic rods are stretched, so that the two pressure plates can be moved downward smoothly, realizing the vertical fixation of the metal plate. The vertical and horizontal clamping cooperation can clamp the metal plate firmly, facilitate the subsequent processing operations of the metal plate, and improve the processing quality of the metal plate. At the same time, the clamping position can be protected during clamping to avoid damage during clamping.

[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0006] The existing clamping structure for thin metal processing mainly uses the first clamping mechanism and the second clamping mechanism to perform clamping functions in different directions to achieve a fixing effect. However, in actual use, since the first clamping mechanism and the second clamping mechanism are independent of each other and need to be independently controlled in movement, more power components are required and the cost is high. Utility Model Content

[0007] In order to overcome the shortcomings of the existing clamping structure for thin metal processing, that is, the first clamping mechanism and the second clamping mechanism are independent of each other, and need to independently control the movement, need to use more power elements and have high cost, the embodiment of the present application provides a clamping structure for metal processing, an electric telescopic push rod controls the two assembly slides to approach each other inside the two guide grooves, so that the two clamping bases drive the two second clamping plates to approach each other, and the metal plate can be fixed when the spring between the clamping base and the second clamping plate is compressed, and the second clamping plate pushes the controlled plate on the first clamping plate to drive the buckle plate to swing from one end of the clamping base to the center of one side of the second clamping plate to clamp the metal plate, which is conducive to saving costs.

[0008] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0011] The first clamping plate comprises a gusset plate, and two controlled plates are processed on the surface of one end of the gusset plate, and guide rods are processed at four corners of one side of the second clamping plate.

[0012] In one possible implementation, the electric telescopic rod controls the two assembly slides to approach each other, the metal plate is clamped by two second clamps, and the second clamp compression springs apply pressure to the controlled plates on the two first clamps, so that the buckle plates on the two first clamps approach the center of one side of the second clamp from the top and bottom respectively.

[0013] In a possible implementation, a common connecting plate is provided at one end of the two clamping bases, guide grooves are processed inside both ends of the connecting plate, the electric telescopic rod is assembled to the top of one side of the connecting plate, one end of the assembly slide extends into the guide groove and slides inside it, and the top of the other end of the assembly slide fits with the surface of the connecting plate.

[0014] In a possible implementation, two placement plates are processed on the bottom surface of one side of the connecting plate, and positioning grooves are processed on the tops of the two placement plates.

In the process of clamping the metal plate, on the one hand, the spring between the clamping base and the second clamping plate is compressed to fix the metal plate, and on the other hand, the second clamping plate pushes the controlled plate on the first clamping plate to drive the first clamping plate to rotate at one end of the clamping base, so that the buckle plates on the top and bottom of the second clamping plate swing toward the center of one side of the second clamping plate to clamp the metal plate. In this process, only one electric telescopic rod is needed to provide power, which is conducive to cost saving.

[0027] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0028] Example:

[0029] This embodiment introduces a specific structure of a clamping structure for metal processing. Figure 1-Figure 4 As shown, it includes a second clamping plate 4 and two first clamping plates 3 arranged facing each other up and down, a clamping base 1 is arranged on one side of the second clamping plate 4, a spring 13 is arranged between the second clamping plate 4 and the center of the clamping base 1, two second clamping plates 4 are provided, and the two second clamping plates 4 are arranged symmetrically on the left and right, one end of the two clamping bases 1 are assembled and connected with an assembly slide 10, and an electric telescopic rod is assembled and connected between the two assembly slides 10;

[0030] like Figure 3 and Figure 4 As shown, the first clamping plate 3 includes a gusset plate 301, and two controlled plates 302 are processed on the surface of one end of the gusset plate 301, and guide rods 2 are processed at the four corners of one side of the second clamping plate 4;

[0031] One end of the two first clamping plates 3 is respectively hingedly connected to the top and bottom of the clamping base 1, and the two assembly slides 10 are controlled by the electric telescopic rod to approach each other, and the metal plate is clamped by the two second clamping plates 4, and the second clamping plates 4 compress the springs 13 to apply pressure to the controlled plates 302 on the two first clamping plates 3, so that the buckle plates 301 on the two first clamping plates 3 are respectively approached from the top and bottom to the center of one side of the second clamping plate 4, and finally the top and bottom surfaces of both ends of the metal plate are clamped and fixed;

[0032] Secondly, in order to facilitate the use of the electric telescopic rod to control the two assembly slides 10 to drive the two clamping bases 1 to move closer and farther from each other, the two second clamping plates 4 are used to clamp the metal plate from both ends, and the buckle plates 301 on the two first clamping plates 3 clamp the surface of the metal plate from the top and bottom to the center of one side of the second clamping plate 4, such as Figure 1 and Figure 2As shown, one end of the two clamping bases 1 is provided with the same connecting plate 6, and the inner sides of both ends of the connecting plate 6 are processed with guide notches 8. By assembling the electric telescopic rod to the top of one side of the connecting plate 6, one end of the assembly slide 10 is extended into the inner side of the guide notch 8, and the top of the other end of the assembly slide 10 is made to fit with the surface of the connecting plate 6. When the electric telescopic rod is working, the assembly slide 10 can be controlled to slide inside the guide notch 8. With the surface of the assembly slide 10 supported on the surface of the connecting plate 6, it can be ensured that the clamping base 1 moves against the surface of the connecting plate 6.

[0033] At the same time, in order to facilitate placing the metal plate between the two second clamping plates 4, wait for the second clamping plates 4 and the first clamping plates 3 to be clamped and fixed, such as Figure 1 As shown, two placement plates 5 are processed on the bottom surface of one side of the connecting plate 6, and positioning grooves 7 are processed on the tops of the two placement plates 5. By setting the cross section of the positioning grooves 7 to a right-angle trapezoid, the positioning grooves 7 are used to correct the position of the metal plate when it is placed on the top of the placement plate 5, so that the metal plate is located at the bottom inner wall of the positioning grooves 7, which is convenient for the two clamping bases 1 to drive the corresponding second clamping plates 4 and the first clamping plates 3 to approach each other to clamp and fix the metal plates;

[0034] Furthermore, for convenience, the metal plates are placed on the top of the two placement plates 5 from both sides of the connecting plate 6, such as Figure 2 As shown, a through-plate notch 9 is processed inside the connecting plate 6. By making the two ends of the through-plate notch 9 communicate with the inside of the two guide notches 8 respectively, when the metal plate passes through the inside of the guide notches 8 and is placed on the top of the placement plate 5, it can be positioned by the positioning groove 7;

[0035] In some examples, one end of the guide rod 2 is threadedly connected to the limit nut 12, and supported on the surface of one side of the clamping base 1 by means of the limit nut 12. When the spring 13 is supported between the second clamping plate 4 and the clamping base 1, the springs 13 and 912 are respectively located on both sides of the clamping base 1, so that the guide rod 2 can be restricted from sliding out from the inside of the clamping base 1 to the outside.

[0036] Furthermore, in order to stably place the spring 13 between the clamping base 1 and the second clamping plate 4, as shown in FIG. Figure 3 and Figure 4 As shown, a supporting round rod 14 is processed at the center of one side of the second clamping plate 4, and an external sleeve-type connection of one end of the supporting round rod 14 is provided with an adjusting screw sleeve 11. By sleeve-fitting the spring 13 on the outside of the supporting round rod 14 and sleeve-fitting one end of the supporting round rod 14 on the inner side of the adjusting screw sleeve 11, the second clamping plate 4 can be moved closer to the clamping base 1, and when the spring 13 is compressed, the supporting round rod 14 can slide inside the clamping base 1, and the spring 13 is stably located between the clamping base 1 and the second clamping plate 4;

[0037] At the same time, by threading the adjusting screw sleeve 11 inside the clamping base 1, when it is necessary to adjust the clamping force at both ends of the metal plate, the adjusting screw sleeve 11 can be rotated to adjust the threaded connection with the clamping base 1, so that the adjusting screw sleeve 11 replaces the clamping base 1 to support one end of the spring 13, thereby changing the degree to which the spring 13 is compressed when the clamping base 1 and the second clamping plate 4 are in a natural state, thereby adjusting the force required for the metal plate to subsequently compress the spring 13.

[0038] The above design sets two second clamping plates 4 supported by the clamping base 1 and the spring 13, and independently configures two first clamping plates 3 for the two second clamping plates 4. When the electric telescopic push rod assembled to the surface of one side of the connecting plate 6 controls the two assembly slides 10 to slide inside the two guide slots 8 and approach each other, the two clamping bases 1 can be driven to approach each other, so that the metal plate placed on the top of the two placement plates 5 first contacts the surface of the second clamping plates 4, and then the second clamping plates 4 are used to compress the springs 13 between the clamping base 1 and the clamping base 1, so as to achieve the clamping and fixing work at both ends of the metal plate.

[0039] During this process, the second clamping plate 4 moves toward one side of the clamping base 1, pushing the controlled plate 302 on the first clamping plate 3 to drive the first clamping plate 3 to rotate at one end of the clamping base 1, so that the buckle plates 301 on the top and bottom of the second clamping plate 4 swing toward the center of one side of the second clamping plate 4, and finally support the surface of the metal plate to clamp it;

[0040] At the same time, by adjusting the threaded connection between the adjusting screw sleeve 11 and the clamping base 1, the adjusting screw sleeve 11 replaces the clamping base 1 to support one end of the spring 13, and the degree of compression of the spring 13 is adjusted, thereby adjusting the force required for the subsequent compression of the spring 13 on the metal plate. This can avoid bending of the center area of ​​the metal plate due to excessive clamping force when the two second clamping plates 4 and the four first clamping plates 3 clamp the clamping base 1, thereby ensuring that the metal plate can complete the processing work smoothly.

[0041] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
