Description

Technical Field

[0001] This invention relates to the field of electrical technology, and more particularly to a rivet removal device. Background Technology

[0002] The manufacture of products such as circuit breakers, protectors, and instrument transformers requires the use of rivets. During the production process, some products inevitably require rework. It is necessary to remove the rivets attached to the products in order to open the covers and adjust or rework the internal parts. Returned products also need to be disassembled and reworked in the same way.

[0003] In existing technologies, rivets are typically removed using automatic or semi-automatic devices. Specifically, the rivets are ejected from the product using a rivet-removing pin on the device. In existing technologies, for products with two or more poles, the thickness is greater, and the rivets used to rivet the product are also longer, requiring a correspondingly longer rivet-removing pin.

[0004] Currently, the diameter of the rivets used for rivet assembly in circuit breakers is mostly only 2mm, and the diameter of the rivet removal pin is generally smaller than the diameter of the rivet. If the length of the rivet removal pin is too large, it may bend during rivet removal, and in severe cases, it may break.

[0005] Therefore, there is an urgent need for a rivet removal device to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a rivet removal device that effectively prevents the rivet removal needle from bending and breaking.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A rivet removal device is provided, comprising:

[0009] Positioning fixtures are used to secure products with rivets to be removed.

[0010] Remove the pins and extend them along the first direction;

[0011] A floating positioning module is disposed opposite to the positioning fixture along the first direction. The nail removal pin is fixedly disposed on the floating positioning module, and the floating positioning module is provided with a sliding hole through which the nail removal pin passes.

[0012] A drive module is connected to the floating positioning module. The drive module is used to drive the floating positioning module to abut against the positioning fixture and to deform the floating positioning module so that the rivet removal pin extends relative to the sliding hole along the first direction and squeezes the rivet on the product.

[0013] Optionally, the floating positioning module includes an upper template, a floating positioning plate, and a first damping component. The nail removal pin is fixedly connected to the upper template, and the upper template is drivenly connected to the driving module. At least one floating positioning plate is provided, which is disposed between the upper template and the positioning fixture and arranged along the first direction. The sliding hole is formed on the floating positioning plate. The first damping component is disposed between the upper template and the floating positioning plate adjacent to the upper template. The first damping component causes the floating positioning plate adjacent to the upper template to have a tendency to move away from the upper template.

[0014] Optionally, the floating positioning module includes at least two floating positioning plates, and a second damping component is provided between adjacent floating positioning plates, the second damping component causing the floating positioning plates to tend to move away from each other.

[0015] Optionally, the first damping component includes at least one elastic element, and the second damping component includes at least one resistance cylinder; wherein, when the floating positioning plate adjacent to the positioning fixture is separated from the positioning fixture, the sum of the forces on all the elastic elements is less than the sum of the pressures output by all the resistance cylinders.

[0016] Optionally, when the floating positioning plate adjacent to the positioning fixture is separated from the positioning fixture, the distances between adjacent floating positioning plates and between the upper template and the floating positioning plate adjacent to the upper template are equal.

[0017] Optionally, the upper template is connected to a positioning sleeve, and the positioning fixture is connected to a positioning post, the positioning post being slidably inserted through the positioning sleeve.

[0018] Optionally, the end of the rivet-removing pin used to press the rivet is tapered.

[0019] Optionally, the positioning fixture includes a fixture frame and a pad, wherein the fixture frame is provided with a plurality of limiting grooves at intervals along the first direction; the pad is inserted into one of the limiting grooves and forms a receiving groove with the fixture frame for accommodating the product.

[0020] Optionally, the drive module includes a mounting plate, a drive cylinder, and a guide post. The mounting plate is disposed corresponding to the positioning fixture along the first direction. The drive cylinder is fixedly disposed on the mounting plate and connected to the floating positioning module. The first end of the guide post is fixedly connected to the mounting plate, the second end of the guide post is fixedly connected to the positioning fixture, and the floating positioning module is slidably connected to the guide post.

[0021] Optionally, the nail removal pins are provided in at least one group, each group including at least one nail removal pin, and the nail removal pins in different groups have different lengths.

[0022] Beneficial effects:

[0023] The rivet removal device provided by the present invention controls the drive module to drive the floating positioning module to move. While the rivet removal pin moves toward the positioning fixture, the floating positioning module will abut against the positioning fixture and deform, so that the rivet removal pin slides relative to the sliding hole along the first direction toward the positioning fixture and gradually extends and squeezes the rivet on the product to complete the removal of the rivet. In this process, the sliding hole can effectively restrict the rivet removal pin, ensure the straightness of the rivet removal pin, and thus prevent the rivet removal pin from bending or breaking.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0046] Reference Figures 1 to 3 As shown, this embodiment provides a rivet removal device, including a positioning fixture 100, a rivet removal needle 200, a floating positioning module 300, and a drive module 400.

[0047] Specifically, the positioning fixture 100 is used to fix the product 10 with the rivet 20 to be removed.

[0048] Specifically, the rivet removal pin 200 extends along a first direction and is used to press the rivet 20 on the product 10 to remove the rivet 20. Figure 1 In this context, direction 'a' is the first direction, and the first direction can be vertical. For example, product 10 includes, but is not limited to, circuit breakers, protectors, and current transformers.

[0049] Specifically, the floating positioning module 300 is arranged opposite to the positioning fixture 100 along the first direction, the floating positioning module 300 is fixedly provided with a nail removal needle 200, and the floating positioning module 300 is provided with a sliding hole 301 through which the nail removal needle 200 passes.

[0050] Specifically, the drive module 400 is connected to the floating positioning module 300. The drive module 400 drives the floating positioning module 300 to abut against the positioning fixture 100 and deforms the floating positioning module 300 so that the rivet removal pin 200 extends relative to the sliding hole 301 in a first direction and presses the rivet 20 on the product 10. For example, the drive module 400 can drive the floating positioning module 300 to move in the first direction.

[0051] In this embodiment, the deformation of the floating positioning module 300 refers to the movement of the component of the floating positioning module 300 with the sliding hole 301 relative to the nail removal needle 200 along the first direction. Specifically, when the floating positioning module 300 abuts against the positioning fixture 100, under the continuous force applied by the driving module 400, the shape of the nail removal needle 200 remains constant, and the floating positioning module 300 is continuously compressed, resulting in deformation. That is, the component of the floating positioning module 300 with the sliding hole 301 moves towards the end of the nail removal needle 200 that is fixedly connected to the floating positioning module 300, thereby causing the component of the floating positioning module 300 with the sliding hole 301 to move relative to the nail removal needle 200, so as to realize the extension of the nail removal needle 200 along the first direction.

[0052] In this embodiment, the control drive module 400 drives the floating positioning module 300, which moves the rivet removal needle 200 toward the positioning fixture 100. At the same time, the floating positioning module 300 will deform against the positioning fixture 100, so that the rivet removal needle 200 slides relative to the sliding hole 301 toward the positioning fixture 100 in the first direction and gradually extends and squeezes the rivet 20 on the product 10, thus completing the removal of the rivet 20. During this process, the sliding hole 301 can effectively restrict the rivet removal needle 200, ensure the straightness of the rivet removal needle 200, and thus prevent the rivet removal needle 200 from bending or breaking.

[0053] In this embodiment, reference is made to Figure 1 and Figure 4 As shown, the positioning fixture 100 includes a fixture frame 110 and a pad 120. Specifically, the fixture frame 110 is provided with a plurality of limiting grooves 1121 spaced apart along a first direction; the pad 120 is inserted into one of the limiting grooves 1121 and forms a receiving groove 1101 with the fixture frame 110 for accommodating the product 10. The limiting grooves 1121 extend along a second direction. Figure 1 In this embodiment, direction b is the second direction, and the second direction can be horizontal. By adjusting the insertion position of the pad 120, the size of the receiving groove 1101 is changed, allowing products 10 with different pole numbers to be placed within the receiving groove 1101, thus making the rivet removal device suitable for removing rivets 20 from products 10 with different pole numbers. For example, the number of limiting grooves 1121 is three to six. To accommodate products 10 with other pole numbers, the number of limiting grooves 1121 can also be other numbers. This can be understood as setting the number of limiting grooves 1121 according to the upper limit of the pole number of the product 10 from which rivets 20 are to be removed, so that the positioning fixture 100 meets the requirements for placing products 10 with different pole numbers.

[0054] Specifically, the jig frame 110 includes a jig platform 114, a jig top plate 111 disposed on the jig platform 114, jig side plates 112 disposed on both sides of the jig top plate 111 along a second direction, and a jig bottom plate 113 disposed on one side of the jig top plate 111 along a third direction. An opening groove facing the third direction is formed between the jig platform 114, the jig top plate 111, the jig side plates 112, and the jig bottom plate 113. Figure 1 In this embodiment, direction c is the third direction, which can be horizontal. Both jig side plates 112 are provided with limiting grooves 1121 spaced apart along the first direction. The limiting grooves 1121 on the two jig side plates 112 correspond one-to-one along the second direction. When the pad 120 is inserted into the limiting groove 1121 along the third direction and abuts against the base plate, the product 10 is inserted into the receiving groove 1101 from the third direction and abuts against the jig base plate 113 to ensure the positioning accuracy of the product 10.

[0055] In one feasible implementation, such as Figure 4 As shown, in order to make the fixture frame 110 structure compact, a limiting groove 1121 can be formed between the fixture platform 114 and the fixture side plate 112.

[0056] In one feasible implementation, such as Figure 4 and Figure 5 As shown, the rivet removal needle 200 can pass through the top plate 111 of the fixture to act on the rivet 20 of the product 10 in the receiving groove 1101. To further ensure the straightness of the rivet removal needle 200, a first guide sleeve 1131 can be provided on the top plate 111 of the fixture. The first guide sleeve 1131 has a first guide hole 11311, and the rivet removal needle 200 passes through the first guide hole 11311. The first guide sleeve 1131 restricts the rivet removal needle 200. Furthermore, the first guide sleeve 1131 can be fixed to the top plate 111 of the fixture by a first screw connector 1132. The first screw connector 1132 can be a thin-head screw. Specifically, the first guide sleeve 1131 is provided with a first ring lug 11312, and multiple first screw connectors 1132 are provided, such as two. The first screw connectors 1132 are threadedly connected to the top plate 111 of the fixture. The head of the first screw connector 1132 presses the first ring lug 11312 against the top plate 111 of the fixture to achieve a fixed connection. In this embodiment, to avoid interference and make the fixture frame 110 structure compact, a first countersunk groove is formed on the top plate 111 of the fixture to accommodate the guide sleeve and the thin-head screw. The first countersunk groove can be a stepped groove, and the first ring lug 11312 is located in the small end of the first countersunk groove.

[0057] In one feasible implementation, such as Figure 1As shown, to collect the removed rivets 20 from product 10, a storage box 500 can be installed below the jig platform 114. The removed rivets 20 will automatically fall into the storage box 500. Specifically, multiple support members 1141 are fixedly installed at the bottom of the jig platform 114. The support members 1141 can be rod-shaped. The installation of the support members 1141 creates a space below the jig platform 114 for placing the storage box. Furthermore, to facilitate leveling of the jig platform 114, the support members 1141 can be feet.

[0058] In this embodiment, reference is made to Figure 1 , Figure 2 and Figure 6 As shown, the drive module 400 includes a mounting plate 410, a drive cylinder 420, and a guide post 430. The mounting plate 410 is positioned corresponding to the positioning fixture 100 along a first direction. The drive cylinder 420 is fixedly mounted on the mounting plate 410 and connected to the floating positioning module 300. The first end of the guide post 430 is fixedly connected to the mounting plate 410, and the second end is fixedly connected to the positioning fixture 100. The floating positioning module 300 is slidably connected to the guide post 430. Specifically, the second end of the guide post 430 is fixedly connected to the fixture platform 114. In this embodiment, the floating positioning module 300 is driven to move along the first direction by the drive cylinder 420, which facilitates control and ensures reliable transmission. Under the action of the guide post 430, the stability of the floating positioning module 300's movement is effectively guaranteed.

[0059] In one feasible implementation, the drive module 400 includes a plurality of guide posts 430, which make multiple sliding contacts with the floating positioning module 300 to ensure the stability of the floating positioning module 300 moving in the first direction.

[0060] In one feasible embodiment, the drive module 400 further includes two manual valves 440 connected to the drive cylinder 420, and the two manual valves 440 are connected in parallel. When only the control button of one manual valve 440 is opened or closed, the extension end of the drive cylinder 420 remains in its original position and does not move. Only when both manual valves 440 are opened or closed simultaneously can the drive cylinder 420 drive the floating positioning module 300 to move. The two manual valves 440 are respectively located on both sides of the fixture platform 114 along the second direction. For example, to ensure the control stability of the drive cylinder 420, a cylinder with a diameter of 100mm can be selected. For example, the drive cylinder 420 can also be replaced with an electric or hydraulic drive device; this application does not limit this.

[0061] In this embodiment, at least one set of rivet removal pins 200 is provided, and each set includes at least one rivet removal pin 200, so that the rivet removal device can remove multiple rivets 20 at the same time, that is, it can remove the rivets 20 on the product 10 at the same time.

[0062] In one feasible implementation, such as Figure 7 As shown, the rivet removal pin 200 is used to press the tapered end of the rivet 20 to create the clearance space required for the deformation of the rivet 20, allowing the rivet 20 to be smoothly removed from the product 10. Specifically, as... Figure 3 As shown, the end of the rivet 20 has a mushroom-shaped flange. By pressing it with the rivet removal needle 200, the flange is rolled and deformed towards the rivet removal needle 200, so that the rivet 20 can be smoothly ejected from the mounting hole in the product 10.

[0063] In one feasible implementation, the drive cylinder 420 has limited output power. To ensure that the drive cylinder 420 can complete the task of removing the rivet 20, when multiple sets of rivet removal pins 200 are provided, the lengths of the rivet removal pins 200 in different sets can be different. This can be understood as follows: by having different lengths of the rivet removal pins 200 in different sets, the drive load on the drive module 400 can be reduced, preventing the drive module 400 from being overloaded and unable to push the rivet 20 out of the product 10. Specifically, when the floating positioning module 300 drives the rivet removal pins 200 to move along the first direction toward the product 10 on the positioning fixture 100, the rivet removal pins 200 contact and press with the rivets 20 in a series of time periods. Since the maximum force exerted by the rivet removal pins 200 on the rivets 20 is the force that causes the flange of the rivets 20 to deform, as the flange gradually becomes similar to a cylindrical shape, the resistance of the rivets 200 on the rivet removal pins 200 almost completely disappears. The flange of the rivets 20 is squeezed and deformed in a series of time periods. It can be understood that different groups of rivet removal pins 200 bear almost all the pressure of the drive cylinder 420 in turn. Therefore, when the drive module 400 is selected, a low-load drive device can be used, and the removal of rivets 20 can also be completed on some products 10 with strong and numerous rivets 20.

[0064] Specifically, the length difference between different groups of rivet removal pins 200 is greater than or equal to the diameter of the rivet 20, enabling the flange of the rivet 20 to be compressed and deformed sequentially in a series of groups. For example, two groups of rivet removal pins 200 can be provided, and depending on the diameter of the rivet 20, the diameter D of the rivet removal pins 200 can be either 1.5mm or 1.9mm. The end taper α used to compress the rivet 20 can be 30°, and the end face diameter d used to compress the rivet 20 can be 0.3mm. The lengths of the two groups of rivet removal pins 200 are 190mm and 192mm, respectively. Of course, depending on parameters such as the strength and number of the rivets 20, the rivet removal pins 200 can also be designed with other sizes and structures; this application does not limit this designation.

[0065] In this embodiment, reference is made to Figure 1 , Figure 8 and Figure 9 As shown, the floating positioning module 300 includes an upper template 310, a floating positioning plate 320, and a first damping component 330. The upper template 310 is fixedly connected to a nail removal pin 200 and is drivenly connected to a drive module 400. At least one floating positioning plate 320 is provided, positioned between the upper template 310 and the positioning fixture 100 and arranged along a first direction. Each floating positioning plate 320 has a sliding hole 301. The first damping component 330 is positioned between the upper template 310 and the floating positioning plate 320 adjacent to the upper template 310, causing the floating positioning plate 320 adjacent to the upper template 310 to tend to move away from the upper template 310. In this embodiment, when the floating positioning plate 320 adjacent to the positioning fixture 100 moves toward and contacts the positioning fixture 100, the upper template 310 and the floating positioning plate 320 will move closer together. The rivet 200 gradually slides out of the floating positioning module 300 and acts on the rivet 20 of the product 10 on the positioning fixture 100. As the upper template 310 moves away from the positioning fixture 100, the floating positioning plate 320 gradually resets under the action of the first damping component 330. The structure is simple and reliable, and can effectively limit the rivet 200.

[0066] In one feasible implementation, the floating positioning module 300 includes at least two floating positioning plates 320, and a second damping component 340 is disposed between adjacent floating positioning plates 320. When one floating positioning plate 320 is provided, such as Figure 10As shown, the floating positioning module 300 does not include the second damping component 340. The second damping component 340 causes the floating positioning plates 320 to tend to move away from each other. In this embodiment, when the floating positioning plate 320 adjacent to the positioning fixture 100 moves towards and contacts the positioning fixture 100, the floating positioning plates 320 will move closer together, and the rivet 200 will gradually slide out of the floating positioning module 300 and act on the rivet 20 of the product 10 on the positioning fixture 100. As the upper template 310 moves away from the positioning fixture 100, under the action of the second damping component 340, the floating positioning plate 320 gradually returns to its original position. The structure is simple and reliable, and it can more effectively restrict the rivet 200.

[0067] Specifically, the floating positioning plate 320 is designed to ensure the straightness of the nail removal pin 200. Its number can be determined according to parameters such as the length and diameter of the nail removal pin 200. Theoretically, the longer and thinner the nail removal pin 200 is, the more floating positioning plates 320 will be required.

[0068] Specifically, the floating positioning module 300 has a natural state and a compressed state. The natural state refers to the floating positioning plate 320 adjacent to the positioning fixture 100 being separated from the positioning fixture 100. The compressed state refers to the floating positioning plate 320 adjacent to the positioning fixture 100 being in contact with the positioning fixture 100, and the distance between the floating positioning plate 320 and the upper template 310 is less than the distance between the floating positioning plate 320 and the upper template 310 when the floating positioning module 300 is in the natural state.

[0069] For example, under the action of the drive module 400, the floating positioning module 300 moves toward the positioning fixture 100 along the first direction. Initially, the floating positioning plate 320 adjacent to the positioning fixture 100 will not contact the positioning fixture 100. Under the action of the first damping component 330 and the second damping component 340, a certain distance is maintained between the adjacent floating positioning plates 320 and between the upper template 310 and the floating positioning plate 320 adjacent to the upper template 310, that is, the floating positioning module 300 is in a natural state. As time goes by, the floating positioning plate 320 adjacent to the positioning fixture 100 will come into contact with the positioning fixture 100. Under the action of the first damping component 330 and the second damping component 340, the adjacent floating positioning plates 320 and the upper template 310 and the floating positioning plate 320 adjacent to the upper template 310 will move closer to each other, that is, the floating positioning module 300 is in a compressed state. At the same time, the rivet removal pin 200 slides relative to the sliding hole 301 of the floating positioning plate 320, that is, the rivet removal pin 200 gradually slides out of the floating positioning module 300 and acts on the rivet 20 of the product 10 on the positioning fixture 100. Through the design of the floating positioning plate 320, the rivet removal pin 200 is well restricted, thereby preventing the rivet removal pin 200 from bending or breaking.

[0070] In one feasible implementation, the first damping assembly 330 includes at least one elastic element 330a, and the second damping assembly 340 includes at least one resistance cylinder 340a. For example, the first damping assembly 330 includes two elastic elements 330a, and the second damping assembly 340 includes two resistance cylinders 340a. Exemplarily, the elastic element 330a can be a spring, and the resistance cylinder 340a can be selected with a cylinder diameter of 12mm.

[0071] In this embodiment, the elastic element 330a is cheaper than the resistance cylinder 340a. When the floating positioning plate 320 adjacent to the positioning fixture 100 comes into contact with the positioning fixture 100, the elastic element 330a provides cushioning, effectively preventing vibration of the rivet removal device from affecting the rivet removal operation. Furthermore, the resistance cylinder 340a has a front end interface (not shown) and a rear end interface 341. Only the rear end interface 341 is connected to the compressed air equipment. When the extension end of the resistance cylinder 340a is subjected to pressure greater than its output thrust, it will retract. In this embodiment, the inclusion of the resistance cylinder 340a prevents the floating positioning plate 320 from reciprocating along the first direction, reducing wear on the rivet removal pin 200 and extending its service life.

[0072] In one feasible implementation, when the floating positioning module 300 is in its natural state, that is, when the floating positioning plate 320 adjacent to the positioning fixture 100 is separated from the positioning fixture 100, the distances between adjacent floating positioning plates 320 and between the upper template 310 and the floating positioning plate 320 adjacent to the upper template 310 are equal. This can be understood as equally spacing along the length direction to limit the portion of the nail removal needle 200 that has not penetrated the top plate 111 of the fixture, which can more effectively ensure the straightness of the nail removal needle 200. Specifically, when the floating positioning module 300 is in its natural state, the sum of the forces on all elastic elements 330a is less than the sum of the pressures output by all resistance cylinders 340a, that is, the extension end of the cylinder can remain fully extended, thereby ensuring that when the floating positioning module 300 is in its natural state, the distances between adjacent floating positioning plates 320 and between the upper template 310 and the floating positioning plate 320 adjacent to the upper template 310 are equal.

[0073] For example, when the lengths of the nail removal pins 200 are 190mm and 192mm respectively, the floating positioning module 300 includes two floating positioning plates 320. When the floating positioning module 300 is in its natural state, the distance between adjacent floating positioning plates 320 and between the upper template 310 and the floating positioning plate 320 adjacent to the upper template 310 can both be 45mm.

[0074] In one feasible implementation, a plurality of first linear bearings 311, corresponding one-to-one with the guide posts 430, are fixedly installed on the upper template 310 to ensure the stability of the upper template 310 moving along the first direction. The number of first linear bearings 311 is less than or equal to the number of guide posts 430.

[0075] In one feasible implementation, each floating positioning plate 320 is provided with a plurality of second linear bearings 321 that are slidably sleeved on the guide post 430 in a one-to-one correspondence. When the floating positioning module 300 includes a plurality of floating positioning plates 320, the number of second linear bearings 321 on each floating positioning plate 320 is less than the number of guide posts 430. The second linear bearings 321 between adjacent floating positioning plates 320 are staggered to form a clearance, so that adjacent floating positioning plates 320 can fit together. While ensuring that the floating positioning plates 320 move stably along the first direction, the structure of the floating positioning module 300 is compact.

[0076] For example, such as Figure 8 As shown, there are four guide columns 430 and four first linear bearings 311, two floating positioning plates 320, and two second linear bearings 321 on each floating positioning plate 320.

[0077] In one feasible embodiment, the telescopic end of the resistance cylinder 340a is provided with an adjusting member 343. For example... Figure 9 As shown, specifically, taking the floating positioning module 300 including two floating positioning plates 320 as an example, the floating positioning module 300 includes a first floating positioning plate 320a and a second floating positioning plate 320b. The first floating positioning plate 320a is located on the side of the second floating positioning plate 320b facing away from the template 310. The cylinder body of the resistance cylinder 340a is fixed on the first floating positioning plate 320a. The adjusting member 343 can move relative to the telescopic end of the resistance cylinder 340a along a first direction, and the adjusting member 343 abuts against the second floating positioning plate 320b. By adjusting the position of the adjusting member 343 relative to the telescopic end of the resistance cylinder 340a, the parallelism between the two floating positioning plates 320 is ensured, thereby preventing the nail removal pin 200 from bending. In this embodiment, the adjusting member 343 can be a screw, which is threadedly connected to the telescopic end of the resistance cylinder 340a. Furthermore, to ensure that the first floating positioning plate 320a can fit snugly with the second floating positioning plate 320b, the adjusting screw can be completely pressed into the first floating positioning plate 320a by the second floating positioning plate 320b. For example, the thickness of the floating positioning plate 320 and the length of the adjusting member 343 can both be 10mm.

[0078] In one feasible implementation, such as Figure 11As shown, each of the floating positioning plates 320 is provided with a second guide sleeve 322 corresponding to a nail removal pin 200. The second guide sleeve 322 passes through the sliding hole 301 and has a second guide hole 3221. The nail removal pin 200 passes through the second guide hole 3221, and the sliding hole 301 restricts the nail removal pin 200 through the second guide sleeve 322. Furthermore, the second guide sleeve 322 can be fixed to the floating positioning plate 320 by a second screw connector 323. The second screw connector 323 can be a thin-head screw. Specifically, the second guide sleeve 322 is provided with a second ring lug 3222, and multiple second screw connectors 323 are provided, for example, two. The second screw connectors 323 are threadedly connected to the floating positioning plate 320, and the head of the second screw connector 323 presses the second ring lug 3222 against the floating positioning plate 320 to achieve a fixed connection. In this embodiment, to avoid interference and make the floating positioning module 300 compact, a second recess is provided on the floating positioning plate 320 to accommodate the guide sleeve and the thin-head screw. The second recess can be a stepped groove, and the second ring lug 3222 is located within the smaller end of the second recess.

[0079] In this embodiment, reference continues to be made to... Figure 8 and Figure 9 As shown, the floating positioning module 300 also includes a pull rod 351. The first end of the pull rod 351 is slidably connected to the upper template 310, and the first end of the pull rod 351 is provided with a stop 3511 to prevent the pull rod 351 from detaching from the upper template 310. The second end of the pull rod 351 passes through the floating positioning plate 320 in sequence, and the second end of the pull rod 351 is fixedly connected to the floating positioning plate 320 adjacent to the positioning fixture 100. The pull rod 351, in conjunction with the first damping component 330 and the second damping component 340, restricts the positional relationship between the upper template 310 and the floating positioning plate 320 along the first direction. The structure is simple and easy to assemble. Specifically, the floating positioning module 300 also includes a limiting member 352. The limiting member 352 passes through the floating positioning plate 320 adjacent to the positioning fixture 100 and is threadedly connected to the second end of the pull rod 351, thereby realizing the fixed connection between the pull rod 351 and the floating positioning plate 320 adjacent to the positioning fixture 100. The limiting member 352 can be a bolt. In this embodiment, the elastic member 330a is sleeved on the pull rod 351, and the first end of the elastic member 330a abuts against the upper template 310. The second end of the elastic member abuts against the floating positioning plate 320 adjacent to the upper template 310. The upper template 310 and the floating positioning plate 320 adjacent to the upper template 310 are both provided with grooves to accommodate the elastic member 330a, so as to limit the radial position of the elastic member 330a.

[0080] Furthermore, multiple tie rods 351 are provided, such as two to four, to ensure the parallelism between the upper template 310 and the floating positioning plate 320.

[0081] In one feasible implementation, the floating positioning module 300 further includes an upper module 360 ​​fixedly connected to the upper template 310. The upper module 360 ​​is located on the side of the upper template 310 facing the floating positioning template. The end of the nail removal needle 200 connected to the upper template 310 is provided with a positioning protrusion 210. The upper module 360 ​​is provided with a first through hole 361 for accommodating the nail removal needle 200. The first through hole 361 is stepped, with the larger end of the first through hole 361 facing the upper template 310. The first end of the positioning protrusion 210 fits against the upper template 310, and the second end of the positioning protrusion 210 fits against the stepped surface of the first through hole 361, thereby achieving the fixation of the nail removal needle 200 relative to the upper template 310.

[0082] In this embodiment, reference is made to Figure 6 , Figure 8 and Figure 9 As shown, to ensure the positional accuracy of the rivet removal pin relative to the positioning fixture 100, a positioning sleeve 370 is connected to the upper template 310, and a positioning post 130 is connected to the positioning fixture 100. The positioning post 130 can slide through the positioning sleeve 370 to guide the movement of the rivet removal pin 200 along the first direction. In this embodiment, before the rivet removal pin 200 presses against the rivet 20 of the product 10 on the positioning fixture 100, the positioning post 130 will first pass through the positioning sleeve 370, thereby enabling the rivet removal pin 200 to accurately correspond to the position of the rivet 20 of the product 10, ensuring that the rivet 20 can be removed smoothly. Specifically, at least one positioning sleeve 370 and one positioning post 130 are provided, for example, two of each. Of course, the positioning post 130 can also always pass through the positioning sleeve 370.

[0083] Specifically, the upper module 360 ​​is provided with a second through hole 362, the first end of the positioning sleeve 370 passes through the second through hole 362, the second end of the positioning sleeve 370 is provided with a positioning ring 371, the upper template 310 is provided with a positioning groove to accommodate the positioning ring 371, one end of the positioning ring 371 abuts against the upper module 360, and the other end of the positioning ring 371 abuts against the bottom of the positioning groove, thereby realizing the fixation of the positioning sleeve 370 relative to the upper template 310.

[0084] For example, taking the floating positioning module 300, which includes two floating positioning plates 320, as an example, the specific usage method of the rivet removal device provided in this embodiment is as follows:

[0085] First, according to the number of poles of product 10, insert the pad 120 into the suitable limiting groove 1121 of the fixture frame 110, and place product 10 into the receiving groove 1101. Then, open the two manual valves 440, so that the drive module 400 drives the floating positioning module 300 to move the nail removal pin 200 toward product 10 in the first direction.

[0086] During this process, the second floating positioning plate 320b first fits against the top plate 111 of the fixture, so that the upper template 310, the first floating positioning plate 320a and the second floating positioning plate 320b move closer to each other. The nail removal pin 200 slides out of the floating positioning module 300 relative to the first floating positioning plate 320a and the second floating positioning plate 320b, and the positioning post 130 is inserted into the positioning sleeve 370 before the nail removal pin 200 squeezes the rivet 20, until the first floating plate and the second floating plate and the first floating positioning plate 320a and the upper module 360 ​​fit together, and the rivet 20 is squeezed into the storage box 500 by the nail removal pin 200.

[0087] Note: For connection methods not explicitly mentioned in the text, common fixing connection methods such as threaded connection, welding or bonding can be used as needed.
