Description

Technical Field

[0001] This utility model relates to the field of electrode cap removal technology, and in particular to an electrode cap removal device. Background Technology

[0002] Electrode caps are core consumables in resistance welding equipment, primarily used to transmit welding current and apply pressure, causing a weld nugget to form at the contact point on the workpiece to complete the weld. The electrode cap and electrode rod are typically connected by threads. During welding use, the electrode cap needs to be disassembled and replaced periodically to avoid problems such as uneven current distribution and weld defects caused by wear.

[0003] In existing electrode cap removal processes, tools are typically used to disassemble the electrode caps in order to improve disassembly efficiency. For example, utility model patent CN221910667U discloses an electrode cap removal device, including a base and a rotating block. A brake switch is provided on the front of the base, and a connecting block is fixedly connected to the top of the base. A motor is mounted on the upper surface of the connecting block, and the output end of the motor passes through the upper surface of the connecting block and is fixedly connected to the rotating block. A second motor is mounted on the bottom surface of the rotating block, and the output end of the second motor passes through the bottom surface of the rotating block and is fixedly connected to a turntable. A drive block is fixedly connected to the edge of the turntable.

[0004] While the aforementioned utility model patent can replace manual labor for disassembly, reducing manual operations and improving disassembly efficiency, in actual use, due to the threaded connection between the electrode cap and the electrode rod, the electrode cap will experience axial displacement along the thread axis of the electrode rod during rotation. The device lacks a displacement compensation structure, which can easily cause the electrode cap to move on the clamping plate, resulting in slippage. This affects the disassembly efficiency of the electrode cap and can also easily damage it, hindering subsequent repairs.

[0005] Therefore, it is necessary to develop an electrode cap removal device to address the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide an electrode cap removal device that can reduce manual operation, improve the removal efficiency of electrode caps, and avoid causing additional wear to the electrode caps.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses an electrode cap disassembly device, comprising a support column, a first driving component, a second driving component, and a displacement compensation assembly. A mounting block is fixedly connected to the top surface of the support column, and a rotating block is rotatably connected to one side wall of the mounting block. The first driving component is mounted on the mounting block and drives the rotating block to rotate. Two parallel mounting plates are disposed at the end of the rotating block away from the mounting block. The second driving component is disposed on the rotating block and drives the two mounting plates to move in opposite directions simultaneously. Two clamping plates are respectively disposed on the opposite side walls of the two mounting plates. The displacement compensation assembly is disposed on the mounting plates and causes the clamping plates to move axially following the electrode cap.

[0008] Furthermore, the first driving component includes a first motor and a rotating shaft. The first motor is fixedly connected to the side wall of the mounting block. The mounting block is hollow inside. The rotating shaft is coaxially fixedly connected to the output end of the first motor. The rotating shaft passes through the mounting block and is fixedly connected to the side wall of the rotating block.

[0009] Furthermore, the second driving component includes a bidirectional lead screw, the rotating block is hollow inside, the two ends of the bidirectional lead screw are rotatably connected to the inner cavity of the rotating block, a second motor is fixedly connected to the outer wall of the rotating block, and the output end of the second motor is coaxially fixedly connected to one end of the bidirectional lead screw; first sliders are symmetrically fixedly connected to the positive and negative thread sections of the bidirectional lead screw; a strip-shaped hole is opened on the side wall of the rotating block, and connecting blocks are slidably connected to both ends of the strip-shaped hole, one end of the two connecting blocks is fixedly connected to the two first sliders respectively, and the other end of the two connecting blocks is fixedly connected to the two mounting plates respectively.

[0010] Furthermore, the displacement compensation component includes a compression spring, and each of the two mounting plates has a sliding groove on its opposite sidewall. A second slider is slidably connected in the sliding groove, and the second slider is slidably connected in the sliding groove. The clamping plate is fixedly connected to the outer sidewall of the second slider. One end of the compression spring is fixedly connected to the inner wall of the sliding groove, and the other end is fixedly connected to the sidewall of the second slider.

[0011] Furthermore, a slide rod is fixedly connected inside the slide groove, the slide rod passes through the second slider, and the compression spring is sleeved on the outer wall of the slide rod.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This invention features a displacement compensation component on the mounting plate. When the electrode cap moves axially, the second slider slides along the groove, and the compression spring adapts to its extension and retraction, causing the clamping plate to move synchronously with the electrode cap. This ensures that the clamping plate holds the electrode cap in place, preventing the electrode cap from slipping on the clamping plate, improving the efficiency of electrode cap removal, and avoiding additional wear on the electrode cap.

[0016] The core of this invention is to provide an electrode cap removal device that can reduce manual operation, improve the removal efficiency of electrode caps, and avoid causing additional wear to the electrode caps.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0019] It is understood that all electrical components mentioned in this article are electrically connected to the main controller and power supply, and all electrical components mentioned in this article are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices. Therefore, this utility model will not explain the control method and circuit connection in detail. At the same time, all parts not described in detail in this utility model are common technologies known to those skilled in the art.

[0020] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, an electrode cap removal device includes a support column 1, a first driving component, a second driving component, and a displacement compensation assembly. A mounting block 2 is fixedly connected to the top surface of the support column 1. A rotating block 3 is rotatably connected to one side wall of the mounting block 2. The first driving component is mounted on the mounting block 2 and is used to drive the rotating block 3 to rotate. Two parallel mounting plates 4 are provided at the end of the rotating block 3 away from the mounting block 2. The second driving component is mounted on the rotating block 3 and is used to drive the two mounting plates 4 to move in opposite directions simultaneously. Two clamping plates 5 are respectively provided on the side walls of the two mounting plates 4 facing each other. The displacement compensation assembly is mounted on the mounting plates 4 and makes the clamping plates 5 move axially with the electrode cap.

[0021] The first driving component drives the rotating block 3 to rotate, thereby rotating the electrode cap for disassembly. The second driving component simultaneously drives the mounting plate 4 to move closer to or further away, thereby causing the clamping plate 5 to clamp and release the electrode cap. The displacement compensation component adapts to the axial displacement of the electrode cap, adjusting the position of the clamping plate 5 to prevent the electrode cap from slipping and being damaged.

[0022] In one specific embodiment of this utility model, such as Figure 1 As shown, the first driving component includes a first motor 6 and a rotating shaft 7. The first motor 6 is a servo motor and is fixedly connected to the side wall of the mounting block 2 via a flange. The mounting block 2 is hollow inside. The rotating shaft 7 is coaxially fixedly connected to the output end of the first motor 6. The rotating shaft 7 passes through the mounting block 2 and is fixedly connected to the side wall of the rotating block 3.

[0023] The first motor 6 drives the rotating shaft 7 to rotate the rotating block 3, which in turn drives the electrode cap held by the clamping plate 5 to rotate, thus achieving thread removal. The servo motor can precisely control the speed and direction of rotation, avoiding the electrode cap from slipping due to excessive speed.

[0024] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the second driving component includes a bidirectional lead screw 8, and a hollow rotating block 3. Both ends of the bidirectional lead screw 8 are rotatably connected to the inner cavity of the rotating block 3. A second motor 9, specifically a stepper motor, is fixedly connected to the outer wall of the rotating block 3. The output end of the second motor 9 is coaxially and fixedly connected to one end of the bidirectional lead screw 8. First sliders 10 are symmetrically fixedly connected to the positive and negative thread sections of the bidirectional lead screw 8. A strip-shaped hole 11 is opened on the side wall of the rotating block 3, and connecting blocks 12 are slidably connected to both ends of the strip-shaped hole 11. One end of each connecting block 12 is fixedly connected to one of the two first sliders 10, and the other end of each connecting block 12 is fixedly connected to one of the two mounting plates 4.

[0025] By starting the second motor 9, the bidirectional lead screw 8 is driven to rotate, causing the two first sliders 10 to move in opposite directions. Through the connecting block 12, the mounting plate 4 is moved closer to or further away, thereby achieving the clamping and loosening of the electrode cap by the clamping plate 5.

[0026] In one specific embodiment of this utility model, such as Figure 1 As shown, the displacement compensation assembly includes a compression spring 13. Slide grooves 14 are provided on the side walls of the two mounting plates 4 facing each other. A second slider 15 is slidably connected in the slide groove 14. The second slider 15 is slidably connected in the slide groove 14. The clamping plate 5 is fixedly connected to the outer side wall of the second slider 15. One end of the compression spring 13 is fixedly connected to the inner wall of the slide groove 14, and the other end is fixedly connected to the side wall of the second slider 15.

[0027] Specifically, a slide rod 16 is fixedly connected inside the slide groove 14. The two ends of the slide rod 16 are fixedly connected to the inner walls of the two ends of the seaweed 14, respectively. The slide rod 16 passes through the second slider 15, and the compression spring 13 is sleeved on the outer wall of the slide rod 16.

[0028] Specifically, the two clamping plates 5 have serrated anti-slip textures on their opposite sidewalls to enhance the clamping friction of the clamping plates 5 on the electrode caps.

[0029] When the electrode cap is removed, it moves axially, and the clamping plate 5 drives the second slider 15 to slide along the slide groove 14 to prevent the clamping plate 5 from slipping on the electrode cap. At the same time, the compression spring 13 is compressed. After removal, the clamping plate 5 is reset by the elastic restoring force of the compression spring 13. The slide rod 16 ensures that the second slider moves smoothly and prevents deviation.

[0030] The working principle of this utility model is as follows: When using the electrode cap removal device of this utility model, the second motor 9 is started, and the bidirectional lead screw 8 rotates, driving the first slider 10, the connecting block 12 and the mounting plate 4 to move, so that the clamping plate 5 clamps the electrode cap. The first motor 6 is started, and the rotating shaft 7 drives the rotating block 3 to rotate. The electrode cap rotates synchronously with the clamping plate 5 and exits along the thread axis of the electrode rod. At this time, the second slider 15 slides along the slide groove 14 and compresses the compression spring 13. After the electrode cap is completely removed, under the action of the elastic restoring force of the compression spring 13, the clamping plate 5 is reset. Then the second motor 9 is started in reverse, the clamping plate is released, and the operation is completed.

[0031] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
