[0041] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as limiting the present utility model.

[0042] Referring to Figures 1 to 10 as shown, the present utility model provides a shrapnel positioning and locking device, including a first mounting unit 10, a second mounting unit 20 and a locking unit 30, wherein:

[0043] The first installation unit 10 includes a first mounting plate 11, a first positioning plate 12, and a first driving assembly 13. The first mounting plate 11 is used to carry a first workpiece (not shown). In the embodiment of the present application, the first workpiece is a shrapnel. Referring to Figure 6 As shown, a plurality of positioning holes 111 are provided on the first mounting plate 11. The plurality of positioning holes 111 are used to install the shrapnel. The inner contour surface of the positioning hole 111 is adapted to the outer contour surface of the shrapnel. The shrapnel can be placed in each positioning hole 111 by a manipulator without manual operation. The first mounting plate 11 is detachably arranged on the first positioning plate 12 to facilitate the separation of the first mounting plate 11 from the first positioning plate 12.

[0044] In the embodiment provided by the present application, the first driving assembly 13 is used to drive the first positioning plate 12 to move along a first preset path. The first preset path is the path for the first positioning plate 12 to move to the corresponding position of the second installation unit 20. The first preset path can be a linear path or a non-linear path. Preferably, the first preset path is a linear path moving along a first direction D1. The first direction D1 is a horizontal direction. The first driving assembly 13 can drive the first positioning plate 12 to move horizontally, thereby driving the first mounting plate 11 to move horizontally and realizing the movement of the shrapnel to the corresponding position matching the second installation unit 20.

[0045] The second installation unit 20 includes a second mounting plate 21, a fixing assembly 22, and a second driving assembly 23. The second mounting plate 21 is used to carry a second workpiece 40. Referring to Figure 8 As shown, in the embodiment of the present application, the second workpiece 40 is a material that needs to be locked with the shrapnel. Through the action of the fixing assembly 22, the second workpiece 40 can be fixed on the second mounting plate 21. The second driving assembly 23 is used to drive the second mounting plate 21 to flip a preset angle along its own axis. This preset angle is determined according to needs. After the second workpiece 40 is fixed on the second mounting plate 21, the second driving assembly 23 drives the second mounting plate 21 to flip 180°, so that the second workpiece 40 is flipped to a position facing the first mounting plate 11 to facilitate locking with the first workpiece on the first mounting plate 11. After the second workpiece 40 on the second mounting plate 21 is locked with the first workpiece, the second driving assembly 23 can drive the second mounting plate 21 to flip 180° again. After the first mounting plate 11 synchronously flips 180° with the second mounting plate 21, subsequent operations can be carried out.

[0046] The locking unit 30 includes a third driving component 31 and a locking component 32. The third driving component 31 is used to drive the first mounting plate 11 to move along a second preset path. The starting end of the second preset path coincides with the end of the first preset path. The second preset path is the path for the first mounting plate 11 to move from the end of the first preset path to the end of the second preset path. Preferably, the second preset path in this application is the path for the first mounting plate 11 to move along the direction of gravity. The third driving component 31 is located below the second mounting unit 20 in the direction of gravity. When the first driving component 13 drives the first positioning plate 12 to the end of the first preset path, and after the second mounting plate 21 completes the fixation and flipping of the second workpiece 40, the third driving component 31 is activated to push the first mounting plate 11 to move upward along the direction of gravity until the first mounting plate 11 is in close contact with the second mounting plate 21. Finally, the first mounting plate 11 and the second mounting plate 21 are fixedly matched through the locking component 32, so that the first mounting plate 11 and the second mounting plate 21 form an integral body, and the first workpiece and the second workpiece 40 are locked together.

[0047] Referring to Figures 5 to 7 As shown in the embodiments provided in this application, a positioning portion 124 is provided on the first positioning plate 12, and a positioning mating portion 112 is provided on the first mounting plate 11. When the first mounting plate 11 is placed on the first positioning plate 12, the positioning portion 124 and the positioning mating portion 112 form a positioning fit, so that the first mounting plate 11 can only move along the second preset path relative to the first positioning plate 12. That is, the positioning fit between the positioning portion 124 and the positioning mating portion 112 can ensure that the first mounting plate 11 and the first positioning plate 12 can only be separated in the direction of gravity, and in other directions, the first mounting plate 11 and the first positioning plate 12 are relatively stationary; when the first mounting plate 11 is taken away from the first positioning plate 12, the positioning fit between the positioning portion 124 and the positioning mating portion 112 is released, thereby realizing the separable connection between the first positioning plate 12 and the first mounting plate 11.

[0048] In a feasible embodiment, the positioning portion 124 includes a plurality of intersecting positioning protrusions, and the positioning mating portion 112 includes a plurality of intersecting positioning grooves. When the first mounting plate 11 is disposed on the first positioning plate 12, the plurality of positioning protrusions can respectively extend into the corresponding positioning grooves to form a clearance fit, so as to realize the positioning of the first positioning plate 11.

[0049] Further, the positioning protrusion is a protrusion extending upward along the direction of gravity from the surface of the first positioning plate 12 facing the first mounting plate 11. The positioning portion 124 includes a first protrusion 1241 and a second protrusion 1242. The first protrusion 1241 is provided on the surface of the first positioning plate 12, and the extending direction of the second protrusion 1242 is perpendicular to the extending direction of the first protrusion 1241. The first protrusion 1241 and the second protrusion 1242 together form a cross-shaped positioning portion 124. The positioning groove is a groove recessed from the surface of the first mounting plate 11 facing the first positioning plate 12. The positioning and mating portion 112 includes a first positioning groove 1121 and a second positioning groove 1122. The shape and position of the first positioning groove 1121 are adapted to the first protrusion 1241, and the shape and position of the second positioning groove 1122 are adapted to the second protrusion 1242. The first positioning groove 1121 and the second positioning groove 1122 together form a cross-shaped positioning and mating portion 112.

[0050] Through the cooperation of the cross-shaped positioning portion 124 and the cross-shaped positioning and mating portion 112, it is possible to limit the first mounting plate 11 to move only up and down along the direction of gravity relative to the first positioning plate 12, ensuring that the first mounting plate 11 can be stably fixed to the first positioning plate 12, and further ensuring the stability of the first workpiece on the first mounting plate 11.

[0051] Preferably, the first protrusion 1241 and the second protrusion 1242 are wedge-shaped protrusions, and both the first positioning groove 1121 and the second positioning groove 1122 are wedge-shaped grooves. Based on the structural characteristics of the wedge shape, the wedge-shaped protrusion and the wedge-shaped groove can further improve the positioning effect of the first positioning plate 12.

[0052] In other embodiments, the positioning portion 124 and the positioning and mating portion 112 may adopt other structures or components that can stably position the first mounting plate 11 on the first positioning plate 12, which are not limited herein.

[0053] Refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown in

[0054] To improve the stability of the first positioning plate 12 during movement, a first slider 134 is provided on the first positioning plate 12. The first slider 134 forms a guiding fit with the first guide rail 133. During the movement of the first positioning plate 12, the first slider 134 moves along the first guide rail 133, thereby improving the stability of the movement of the first positioning plate 12. In the embodiment provided by the present application, first sliders 134 are provided on both opposite sides of the lower surface of the first positioning plate 12, and correspondingly, two first guide rails 133 are provided respectively to correspond thereto, which is beneficial to further improve the stability of the movement of the first positioning plate 12.

[0055] Refer to Figures 8 to 10 As shown, the fixing assembly 22 includes a first cylinder 221 and a second cylinder 222. A first push block 223 is provided at the end of the piston rod of the first cylinder 221, and a second push block 224 is provided at the end of the piston rod of the second cylinder 222. A first limiting block 211 and a second limiting block 212 are provided on the second mounting plate 21. The second workpiece 40 is installed at the corresponding position of the second mounting plate 21. The first cylinder 221 and the first limiting block 211 are located on opposite sides of the second workpiece 40 in the first direction D1. The first direction D1 extends along the up and down direction in the figure. After the first cylinder 221 is started, the piston rod of the first cylinder 221 extends forward in the first direction D1. When the first push block 223 abuts against one side of the second workpiece 40, it pushes the second workpiece 40 to move in the direction close to the first limiting block 211 until the second workpiece 40 abuts against the first limiting block 211. Thus, the fixing of the second workpiece 40 in the first direction D1 is realized.

[0056] The second cylinder 222 and the second limiting block 212 are arranged along the second direction D2. The second direction D2 is a direction perpendicular to the first direction D1. The second direction D2 extends horizontally along the left and right direction in the figure. When the second cylinder 222 is started, the piston rod of the second cylinder 222 extends forward in the second direction D2. When the second push block 224 abuts against one side of the second workpiece 40, it pushes the second workpiece 40 to move in the direction close to the second limiting block 212 until the other side of the second workpiece 40 abuts against the second limiting block 212. Furthermore, the second push block 224 and the second limiting block 212 can realize the fixing of the second workpiece 40 in the second direction D2.

[0057] Under the combined action of the first cylinder 221, the second cylinder 222, the first limiting block 211 and the second limiting block 212, the second workpiece 40 is fixed on the surface of the second mounting plate 21.

[0058] Since the second workpiece 40 fixed to the second mounting plate 21 needs to be flipped before being locked with the first workpiece, in order to prevent the flipped second workpiece 40 from falling under the action of gravity, an adsorption area 24 is provided on the second mounting plate 21. The material is placed in the adsorption area 24. The shape of the adsorption area 24 is adapted to the shape of the second workpiece 40. An adsorbent (not shown in the figure) is provided in the area covered by the adsorption area 24. The adsorbent can tightly adsorb the second workpiece 40 to the adsorption area 24, so that the second workpiece 40 is adsorbed on the surface of the second mounting plate 21. Even if the second mounting plate 21 is flipped, the second workpiece 40 will not fall off the second mounting plate 21, ensuring the smooth progress of the locking process between the first workpiece and the second workpiece 40. Preferably, the adsorbent adsorbs the second workpiece 40 by means of vacuum adsorption.

[0059] In other embodiments, the adsorbent can adopt other structures or components that can adsorb or fix the second workpiece 40 to the surface of the second mounting plate 21, which are not limited herein.

[0060] In a feasible embodiment, the second driving assembly 23 is a second driving motor 231. The output shaft of the second driving motor 231 is in transmission connection with the second mounting plate 21. When the second driving motor 231 is started, it can drive the second mounting plate 21 to rotate a preset angle along its own axis, thereby realizing the flipping of the second mounting plate 21.

[0061] Referring to Figure 2 As shown, the third driving assembly 31 includes a third cylinder 311. The third cylinder 311 is arranged below the second mounting unit 20 in the direction of gravity. When the first positioning plate 12 moves to the lower part of the second mounting unit 20, the third driving assembly 31 is located below the first positioning plate 12. The third cylinder 311 is used to drive the first mounting plate 11 to move up or down in the direction of gravity to approach or move away from the second mounting plate 21.

[0062] In the embodiments provided in the present application, referring to Figure 3 and Figure 5 As shown, a pushing member 312 is provided at the end of the piston rod of the third cylinder 311. A through groove 123 is provided on the first positioning plate 12. When the first positioning plate 12 moves to the end of the first preset path, the pushing member 312 is located below the first positioning plate 12 and is opposite to the position of the through groove 123. After the third cylinder 311 is started, the piston rod of the third cylinder 311 moves up, driving the pushing member 312 to pass through the through groove 123 and abut against the first mounting plate 11. As the piston rod of the third cylinder 311 continues to move up, the first mounting plate 11 is pushed to approach the second mounting plate 21 until the first mounting plate 11 is in close contact with the second mounting plate 21. When the piston rod of the third cylinder 311 moves down, it returns below the first positioning plate 12 and waits for the next upward movement.

[0063] In a feasible implementation manner, with reference to Figure 3 and Figure 5 As shown, two through grooves 123 are symmetrically provided on the first positioning plate 12, and two pushing members 312 are provided at the end of the piston rod of the third cylinder 311. When the first positioning plate 12 moves to the end of the first preset path, the positions of the two pushing members 312 respectively correspond to the two through grooves 123. The two pushing members 312 can improve the stability and reliability of the upward movement of the first mounting plate 11, thereby ensuring the fitting effect between the first mounting plate 11 and the second mounting plate 21.

[0064] With reference to Figure 2 、 Figure 8 and Figure 9 As shown, the locking assembly 32 includes a fourth cylinder 321 and a locking block 322. The fourth cylinder 321 is provided at the edge of the second mounting plate 21. The fourth cylinder 321 is a rotary cylinder. The locking block 322 is connected to the fourth cylinder 321. The fourth cylinder 321 is used to drive the locking block 322 to move along a third preset path. The third preset path is the path along which the locking block 322 rotates around the axis of the output shaft of the rotary cylinder. When the first mounting plate 11 and the second mounting plate 21 are closely attached, at this time, the locking block 322 is located at the starting end of the third preset path, and relative movement can still occur between the first mounting plate 11 and the second mounting plate 21. When the fourth cylinder 321 drives the locking block 322 to rotate to the end of the third preset path, the first mounting plate 11 is clamped between the locking block 322 and the second mounting plate 21, so that the first mounting plate 11 and the second mounting plate 21 form an integral body.

[0065] Based on the above embodiments, the working process of the shrapnel positioning and locking device of the present application is as follows:

[0066] First, the shrapnel is placed in the positioning hole 111 of the first mounting plate 11 through a manipulator. The first driving motor 131 is started to drive the first lead screw 132 to rotate, so that the first positioning plate 12 moves on the first lead screw 132 towards the second mounting unit 20 until it moves below the second mounting unit 20.

[0067] Then the material is placed on the second mounting plate 21. The first cylinder 221 and the second cylinder 222 are started simultaneously. The first cylinder 221 and the second cylinder 222 jointly fix the material on the second mounting plate 21. At the same time, under the action of the adsorbing member, the material is adsorbed on the surface of the second mounting plate 21. Then the second driving motor 231 is started to drive the second mounting plate 21 to flip 180°, so that the second mounting plate 21 flips to a position opposite to the first mounting plate 11.

[0068] Subsequently, the third cylinder 311 is activated, and the piston rod of the third cylinder 311 moves upward, pushing the first mounting plate 11 closer to the second mounting plate 21 until the first mounting plate 11 is in close contact with the second mounting plate 21. Then, the fourth cylinder 321 is activated to drive the locking block 322 to rotate to the bottom surface of the first mounting plate 11 to lock the first mounting plate 11 and the second mounting plate 21 together.

[0069] Finally, the second driving motor 231 is activated again to drive the second mounting plate 21 to flip 180° again. The first mounting plate 11 flips synchronously with the flipping of the second mounting plate 21, and then the screws are automatically locked by a screwdriver to achieve the locking of the elastic sheet.

[0070] The structure, features, and function effects of the present utility model have been described in detail based on the embodiments shown in the drawings. The above are only the preferred embodiments of the present utility model, but the present utility model is not limited to the implementation scope shown in the drawings.
