For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0063] The following is a further description of the embodiments of the present application in conjunction with the accompanying drawings. Figure 1 , define the X-axis direction as the first direction and the Z-axis direction as the second direction.

[0064] See also Figure 1 An embodiment of the present application provides a clamping device 100 , including a positioning mechanism 10 and a loading mechanism 20 .

[0065] Specifically, see Figure 1 , Figure 2 and Figure 3 The positioning mechanism 10 includes a support plate 11, a toggle assembly 12 and a clamping assembly 13. The support plate 11 has a first surface 111 and a second surface 112 relative to each other. The first surface 111 is provided with a plurality of first positioning pins 113. The support plate 11 is provided with a first strip hole 114 and a first through hole 115. The first strip hole 114 is arranged along the X-axis direction. The toggle assembly 12 includes a toggle driving member 121 and a toggle member 122 connected to the toggle driving member 121. The toggle driving member 121 is arranged on the second surface 112. The toggle member 122 is movably inserted in the first strip hole 114 and extends out of the first surface 111. The clamping assembly 13 includes a clamping driving member 131 and a clamping member 132 connected to the clamping driving member 131. The clamping driving member 131 is arranged on the second surface 112, and the clamping member 132 is movably inserted in the first through hole 115.

[0066] The support plate 11 is a plate-like structure. It can be understood that in order to facilitate the support plate 11 to support the toggle assembly 12 and the clamping assembly 13, the second surface 112 of the support plate 11 can be connected with a support leg or other structure to support the support plate 11. The first positioning pin 113 can be provided with two, three, four, etc. When setting the position of the first positioning pin 113, it can be set in an asymmetric manner to achieve foolproofing. The toggle drive 121 can be a cylinder, etc., and the toggle member 122 can be a columnar structure and set along the Z-axis direction. The toggle drive 121 drives the toggle member 122 to slide along the X-axis direction in the first line hole. The clamping drive 131 can be a cylinder, etc., and the clamping drive 131 drives the clamping member 132 to move along the Z-axis direction in the first through hole 115.

[0067] Please also see Figure 4 and Figure 5The loading mechanism 20 includes a carrier plate 21, a sliding member 22 and a cover plate 23. The carrier plate 21 is provided with a plurality of first positioning holes 211 corresponding to the first positioning pins 113. The sliding member 22 is arranged on the side of the carrier plate 21 facing the first surface 111 and is slidably connected to the carrier plate 21. The sliding member 22 is provided with a second through hole 221 and a second strip hole 222. The cover plate 23 is arranged on the side of the carrier plate 21 away from the support plate 11, and is used to cooperate with the carrier plate 21 to clamp the workpiece 200. It can be understood that the cover plate 23 covers the carrier plate 21 to clamp the workpiece 200. Therefore, the structure of the cover plate 23 and the carrier plate 21 can be set according to the actual structure of the workpiece 200 to improve the applicability. The sliding member 22 can be a strip structure, and the sliding member 22 is slidably connected to the carrier plate 21. In the Z-axis direction, the sliding member 22 and the carrier plate 21 are not separated.

[0068] When the carrier 21 is placed on the support plate 11, the first positioning pin 113 is inserted into the first positioning hole 211 to position the carrier 21, the toggle member 122 is inserted into the second through hole 221, and the clamping member 132 is inserted into the second strip hole 222. The toggle driving member 121 drives the toggle member 122 to move in the first strip hole 114 along the X-axis direction, thereby driving the sliding member 22 to move along the X-axis direction, so that the side wall of the second strip hole 222 abuts against the clamping member 132, and the clamping driving member 131 drives the clamping member 132 to move in the opposite direction of the Z-axis direction, so that the clamping member 132 clamps the sliding member 22, thereby fixing the carrier 21.

[0069] The clamping device 100 provided in the present application is provided with a positioning mechanism 10. The support plate 11 in the positioning mechanism 10 can support the carrier 21. The carrier 21 can be initially positioned by cooperating with the first positioning pin 113 through the first positioning hole 211. Then, the toggle driving member 121 can drive the sliding member 22 to move along the X-axis direction through the toggle member 122, so that the side wall of the second strip hole 222 abuts against the clamping member 132. The clamping driving member 131 drives the clamping member 132 to move in the opposite direction of the Z-axis direction to clamp the sliding member 22. In this way, the carrier 21 can be fixed, thereby improving the stability when clamping the workpiece 200, thereby improving the clamping and positioning effect. The cover plate 23 in the material loading mechanism 20 covers the carrier plate 21, and the workpiece 200 can be clamped. After the clamping is completed, the clamping drive 131 drives the clamping member 132 to release the sliding member 22, and the toggle drive 121 drives the toggle member 122 to move in the opposite direction of the X-axis direction, so that the sliding member 22 is reset, and the material loading mechanism 20 with the workpiece 200 clamped can be removed for processing. The clamping device 100 provided in the present application can clamp the workpiece 200 outside the processing equipment (not shown), which can improve the work efficiency. During operation, it is only necessary to place the carrier plate 21 on the support plate 11, and start the toggle assembly 12 and the clamping assembly 13 to complete the positioning of the carrier plate 21, which is easy to operate.

[0070] In some embodiments, see Figure 3 , Figure 4 and Figure 5 The clamping member 132 includes a main body 1321 and a clamping portion 1322. The main body 1321 is connected to the clamping drive 131. The clamping portion 1322 is connected to one end of the main body 1321 away from the clamping drive 131. The cross-sectional area of ​​the clamping portion 1322 parallel to the X-axis direction is larger than the cross-sectional area of ​​the main body 1321 parallel to the X-axis direction. Both the main body 1321 and the clamping portion 1322 can be cylindrical structures. When the sliding member 22 moves along the X-axis direction, the side wall of the second strip hole 222 can abut against the main body 1321, and then the clamping drive 131 drives the clamping member 132 to move, thereby causing the clamping portion 1322 to clamp the sliding member 22.

[0071] In some embodiments, see Figure 3 and Figure 5 , the width of the second strip hole 222 at the beginning along the X-axis direction is smaller than the width at the end, the width of the second strip hole 222 at the beginning along the X-axis direction is larger than the diameter of the main body 1321 and smaller than the diameter of the clamping portion 1322, and the width of the end of the second strip hole 222 along the X-axis direction is larger than the diameter of the clamping portion 1322. In this way, when the carrier 21 is placed on the support plate 11, the clamping portion 1322 of the clamping member 132 can pass through the second strip hole 222. After the sliding member 22 moves along the X-axis direction, the beginning of the second strip hole 222 along the X-axis direction is opposite to the clamping portion 1322, so that the clamping effect of the clamping portion 1322 clamping the sliding member 22 can be improved.

[0072] In some embodiments, see Figure 5 and Figure 6 , a slide groove 212 extending along the X-axis direction is provided on one side of the carrier 21 facing the support plate 11, the cross section of the slide groove 212 is T-shaped, and the opening area of ​​the slide groove 212 is smaller than the area of ​​the bottom of the slide groove 212, the cross section of the sliding member 22 is T-shaped to match the slide groove 212, and the sliding member 22 is slidably arranged in the slide groove 212. In this way, the position of the sliding member 22 and the carrier 21 in the Z-axis direction can be limited, and the sliding member 22 can be prevented from being separated from the carrier 21 in the Z-axis direction, and at the same time, the stability of the carrier 21 in the Z-axis direction is improved after the clamping assembly 13 clamps the sliding member 22.

[0073] In some embodiments, see Figure 5 and Figure 6The loading mechanism 20 also includes a limit pin 24. The sliding member 22 is provided with a limit hole 223. The limit hole 223 is a waist-shaped hole. The limit pin 24 is inserted into the limit hole 223 and connected to the bottom of the slide groove 212. The limit pin 24 is used to cooperate with the limit hole 223 to limit the sliding member 22 in the X-axis direction. In this way, when the sliding member 22 moves along the X-axis direction, the limit pin 24 cooperates with the limit hole 223 to limit the moving distance of the sliding member 22 in the X-axis direction. The limit pin 24 can be a bolt, etc., and the limit hole 223 can be a stepped hole. The opening area of ​​the limit hole 223 toward one end of the support plate 11 is larger than the opening area of ​​the limit hole 223 toward one end of the carrier plate 21. In this way, through the cooperation of the limit pin 24 and the limit hole 223, the position of the sliding member 22 in the Z-axis direction can also be limited.

[0074] In some embodiments, see Figure 4 , Figure 5 and Figure 6 The material loading mechanism 20 further includes a reset assembly 25, which includes a reset member 251 and an elastic member 252. A receiving groove 213 is further provided on the side of the carrier plate 21 facing the support plate 11, and the receiving groove 213 is communicated with the slide groove 212. The reset member 251 and the elastic member 252 are sequentially arranged in the receiving groove 213 along the X-axis direction. The end of the reset member 251 away from the elastic member 252 is inserted into the sliding member 22. The elastic member 252 is used to elastically push the reset member 251 to move in the opposite direction of the X-axis direction, thereby driving the sliding member 22 to reset. The reset member 251 can be a block structure, and a protrusion 2511 can be provided on the side of the reset member 251 facing the sliding member 22. A notch can be provided at the position of the sliding member 22 corresponding to the protrusion 2511, and the protrusion 2511 is inserted into the notch, so that the reset member 251 and the sliding member 22 can move synchronously. The elastic member 252 may be a spring, etc., one end of the elastic member 252 abuts against the groove wall of the accommodating groove 213, and the other end abuts against the reset member 251. When the toggle member 122 drives the sliding member 22 to move along the X-axis direction, the reset member 251 moves synchronously with the sliding member 22, and the reset member 251 compresses the elastic member 252. When the carrier 21 is removed from the support plate 11, the elastic member 252 can push the reset member 251 to move in the opposite direction of the X-axis direction, thereby driving the sliding member 22 to move, so as to facilitate the installation of the carrier 21 on the support plate 11 next time.

[0075] In some embodiments, see Figure 4 and Figure 5 The reset assembly 25 further includes a limit plate 253, which is connected to the side of the carrier plate 21 facing the support plate 11 and covers the receiving groove 213, and is used to limit the reset member 251 and the elastic member 252. By providing the limit plate 253, the reset member 251 and the elastic member 252 can be limited in the receiving groove 213 to prevent the reset member 251 and the elastic member 252 from being displaced in the Z-axis direction.

[0076] In some embodiments, see Figure 4 and Figure 5 A second positioning pin 214 is provided on one side of the carrier plate 21 facing the cover plate 23, and a second positioning hole 231 corresponding to the second positioning pin 214 is provided on the cover plate 23. The second positioning pin 214 is inserted into the second positioning hole 231 to position the cover plate 23. In this way, the cover plate 23 can be positioned by the cooperation between the second positioning pin 214 and the second positioning hole 231, so that the cover plate 23 can be installed on the carrier plate 21.

[0077] In one embodiment, the cover plate 23 and the carrier plate 21 are provided with a plurality of corresponding threaded holes, such as two, three, four, etc. After the cover plate 23 covers the carrier plate 21, bolts can be installed in the threaded holes to fix the cover plate 23 and the carrier plate 21 together, thereby improving the stability of the connection between the cover plate 23 and the carrier plate 21.

[0078] In some embodiments, see Figure 6 The cover plate 23 is provided with a material receiving groove 232 on one side facing the carrier plate 21. The material receiving groove 232 is used to receive the workpiece 200. The cover plate 23 is also provided with a processing hole 233 that penetrates the cover plate 23 and communicates with the material receiving groove 232. The processing hole 233 is used to avoid the workpiece 200 to be processed. It can be understood that the structure of the material receiving groove 232 is adapted to the structure of the workpiece 200 to receive and position the workpiece 200. The structure of the processing hole 233 can be a special-shaped structure, and the part to be processed of the workpiece 200 can be exposed, so that the stability of the cover plate 23 fixing and clamping the workpiece 200 can be improved.

[0079] In some embodiments, see Figure 1 and Figure 3 The first surface 111 of the support plate 11 is provided with a plurality of pads 116 for supporting the carrier plate 21. The number of the pads 116 can be two, four, six, etc. The pads 116 can be made of non-metallic materials, such as plastic steel, etc., so that the carrier plate 21 can be prevented from rigidly contacting the support plate 11, resulting in damage to the carrier plate 21 or the sliding member 22.

[0080] The working process of the clamping device 100 provided in the embodiment of the present application is roughly as follows:

[0081] First, the carrier 21 is placed on the support plate 11. When placing, the first positioning pin 113 is inserted into the first positioning hole 211 to preliminarily position the carrier 21. At this time, the toggle member 122 is inserted into the second through hole 221, and the clamping member 132 is inserted into the second bar hole 222. Then, the toggle driving member 121 and the clamping driving member 131 are started. The toggle driving member 121 drives the toggle member 122 to move along the X-axis direction in the first bar hole 114, thereby driving the sliding member 22 to move along the X-axis direction, so that the side wall of the second bar hole 222 abuts against the clamping member 132. The clamping driving member 131 drives the clamping member 132 to move along the Z-axis direction, so that the clamping member 132 clamps the sliding member 22, thereby fixing the carrier 21.

[0082] Then, the workpiece 200 is placed on the carrier 21, and the cover plate 23 is covered on the carrier 21 and the workpiece 200. The cover plate 23 can be positioned by the second positioning pin 214 and the second positioning hole 231, thereby completing the clamping of the workpiece 200. During the clamping process, the position of the carrier 21 is stable, which can effectively improve the clamping and positioning effect.

[0083] After clamping is completed, the clamping drive 131 and the toggle drive 121 are started, the clamping drive 131 drives the clamping member 132 to loosen the sliding member 22, and the toggle drive 121 drives the sliding member 22 to move in the opposite direction of the X-axis direction through the toggle member 122, thereby resetting the sliding member 22, and then the loading mechanism 20 can be removed from the support plate 11.

[0084] When the loading mechanism 20 is not placed on the support plate 11, the elastic member 252 pushes the reset member 251 in the opposite direction of the X-axis direction, and further pushes the sliding member 22 to prevent the sliding member 22 from sliding in the slide groove 212, so that when the loading plate 21 is placed on the support plate 11, the second through hole 221 on the sliding member 22 corresponds to the position of the toggle member 122, and the second strip hole 222 corresponds to the position of the clamping member 132.

[0085] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
