Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent manufacturing, and specifically relates to an automobile parts processing device. Background Technique

[0002] In the processing of automobile parts, wire harness terminals, as key components for electrical signal transmission, were once connected by soldering in the early stage. With the development of welding technology, spot welders have gradually been applied to the welding of automobile wire harness terminals. By precisely controlling welding parameters (such as current, time, and pressure), a spot welder can achieve a high-precision welding process, ensuring the firmness and reliability of wire harness terminal welding.

[0003] When using the existing spot welder for wire harness terminal welding, its working principle is mainly based on the resistance heating effect. First, the staff accurately place the wire harness terminal under the lower spot welding head of the spot welder. This lower spot welding head has a fixed position and provides stable support for welding. After starting the hydraulic cylinder, the hydraulic cylinder outputs power to push the upper spot welding head downward, making it gradually approach the wire harness terminal. When the upper and lower spot welding heads accurately clamp the wire harness terminal, the circuit is connected. A large current instantly passes through the contact part between the wire harness terminal and the spot welding head. Due to the resistance existing in the contact part, a large amount of resistance heat is generated when the current passes through, causing the metal at the contact of the wire harness terminal to quickly melt and fuse. Subsequently, the current is disconnected, and under the action of pressure, the melted metal cools and solidifies, thus forming a firm solder joint and completing the welding process of the wire harness terminal.

[0004] The existing spot welder has obvious disadvantages in the actual use process. Currently, its operation mostly relies on the staff to hold and sort the wire harness terminals for welding. During the holding process, it is difficult for the staff to avoid some physiological tremors. Even if the tremor amplitude is extremely small, it will have an adverse impact on the welding quality. Because the welding of wire harness terminals requires extremely high precision, a slight tremor may cause the contact position between the wire harness terminal and the spot welding head to shift, resulting in inaccurate welding positions, and then errors such as false welding and missed welding may occur. This will not only cause the wire harness terminal welding to be not firm, affecting the overall electrical conductivity of the wire harness, but also may lead to subsequent automobile circuit failures, increasing the defective rate and rework cost of products, reducing production efficiency, and being unfavorable for large-scale and high-quality production of automobile parts.

[0005] Therefore, the present invention provides an automobile parts processing device. Summary of the Invention

[0006] In order to make up for the deficiencies of the existing technology and solve at least one technical problem proposed in the background technique.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: An automobile part processing device described in the present invention includes a spot welding machine body. A first hydraulic cylinder is fixedly connected to the upper end of the spot welding machine body. The output end of the first hydraulic cylinder is fixedly connected to an upper spot welding head. A lower spot welding head is fixedly connected to one side of the spot welding machine body. A bottom plate is fixedly connected to one side of the spot welding machine body. A second hydraulic cylinder is fixedly connected to the upper surface of the bottom plate. A limiting component is arranged at the output end of the second hydraulic cylinder.

A pressing block is elastically connected inside the connecting plate. A rotating shaft is rotatably connected inside the fixing plate. Connecting rods are fixedly connected to both ends of the rotating shaft. An auxiliary component is arranged inside the connecting rod. The auxiliary component includes a cross bar slidably arranged in the middle of the two connecting rods. A fixing frame is fixedly connected to the lower surface of the cross bar.

[0008] Preferably, a rack plate is fixedly connected to the upper surface of the bottom plate. Gears are fixedly connected to both ends of the rotating shaft. The gears rotate along the rack plate. An auxiliary plate is fixedly connected to one side of the rack plate. A cleaning component is arranged on the upper surface of the bottom plate. The cleaning component includes two positioning frames fixedly connected to the upper surface of the bottom plate. The same hook plate is slidably connected inside the two positioning frames. A fixed semi-ring is slidably arranged inside the hook plate.

[0009] Preferably, the limiting component further includes two pressing plates fixedly connected to the upper surface of the bottom plate. Fixing grooves are respectively formed in the connecting plate at positions corresponding to the two pressing plates. Two groups of connecting grooves are formed inside the connecting plate.

The two first compression springs are fixedly connected to the same conical block. Fixed rods are fixedly connected to the lower surfaces of the two conical blocks. The same pressing block is fixedly connected to the bottom ends of the two fixed rods.

[0010] Preferably, the cross section of the pressing block is convex. The pressing block is used for limiting the wire harness terminal. The pressing block is a metal block. After the second hydraulic cylinder pushes the connecting plate to rotate and the gear moves to the auxiliary plate, the connecting plate moves linearly along the bottom plate, so that the pressing plate is inserted into the fixing groove passively to squeeze the conical block, causing the pressing block to extend out of the connecting plate.

[0011] Preferably, two blocking blocks are fixedly connected to the upper surface of the bottom plate. Push rods are fixedly connected to both ends of the cross bar. A sliding groove is formed in the middle of each connecting rod. The push rod slides along the sliding groove. A spring is fixedly connected between the push rod and the inner wall of the connecting rod.

[0012] Preferably, when the second hydraulic cylinder drives the fixed plate to move, the gear rotates along the rack plate first, driving the connecting plate and the connecting rod to rotate. When the gear moves to the auxiliary plate, the connecting rod is parallel to the bottom plate, and the connecting rod slides. During the sliding process of the connecting rod, the stopper blocks the push rod, the push rod compresses the spring, and the push rod drives the fixed frame to slide passively, driving the rotating roller to adhere to the stains on the surface of the wire harness terminal.

[0013] Preferably, the cleaning assembly further includes a connecting spring fixed in the positioning frame, and a telescopic rod is arranged inside the connecting spring, and the telescopic rod is used for limiting the connecting spring.

[0014] Preferably, a positioning groove is formed on one side of the hook plate, a reciprocating screw is rotatably connected in the positioning groove, a sliding block is slidably connected to the circumferential surface of the reciprocating screw, and a fixed half-ring is fixed to one side of the sliding block, and the fixed half-ring abuts against the rotating roller.

[0015] Preferably, a storage box is fixed on the upper surface of the hook plate, a trigger member is arranged in the storage box, a top block is fixed to the upper surface of the sliding block, a limiting hole is formed on the upper surface of the top block, and the top block presses the trigger member to introduce the cleaning agent in the storage box into the sliding block to soak the fixed half-ring.

After the top block presses the auxiliary block, the auxiliary block presses the second compression spring upward, the auxiliary block moves upward, and the connecting hole inside the auxiliary block is aligned with the positioning hole, so that the cleaning agent flows into the auxiliary block along the positioning hole, and then enters the limiting hole of the top block through the auxiliary block.

[0017] The beneficial effects of the present invention are as follows: 1. For the automotive parts processing equipment of the present invention, the cross bar slides passively in the middle of the connecting rod, driving the fixed frame to move above the workpiece. The rotating roller contacts the automotive wire harness terminal for secondary positioning. At the same time, during the passive sliding process of the rotating roller, it will adhere to and clean the upper surface of the wire harness terminal, and then perform spot welding work. During the spot welding process, the stability of spot welding is improved. This spot welding equipment can effectively fix the automotive wire harness terminal through the cooperation of the positioning component and the auxiliary component, prevent the automotive wire harness terminal from shifting during spot welding, and improve the spot welding accuracy. The elastic connection of the pressing block can avoid damaging the automotive wire harness terminal. The design of the rotating roller can perform secondary positioning and clean the surface of the automotive wire harness terminal at the same time, ensuring the stability of spot welding quality. The overall structure is reasonable, the operation is convenient, the production efficiency and product qualification rate can be improved, and the scrap rate can be reduced.

[0018] 2. For a processing device for automotive parts according to the present invention, when the pressing block moves to contact the terminal of the automotive wire harness, under the elastic force of the first compression spring, the pressing block will firmly press the terminal of the automotive wire harness, thereby realizing the limiting and fixing of the workpiece, ensuring that the workpiece maintains a stable position during the spot welding process. By using the cooperation between the extrusion plate and the fixing groove and the elastic action of the first compression spring, the pressing block can adaptively adjust the pressing force on the terminal of the automotive wire harness, which not only ensures the reliability of the limit but also avoids damaging the workpiece due to excessive pressure. At the same time, the structure is simple and the operation is convenient, which can effectively improve the accuracy and stability of the spot welding operation, and improve the product quality and production efficiency.

[0019] 3. For a processing device for automotive parts according to the present invention, when the triggering member is squeezed, the cleaning agent in the storage box will pass through the channel into the sliding block, and then infiltrate the fixed semi-ring. The cleaning agent can enhance the cleaning effect of the fixed semi-ring on sundries, soften and dissolve some stubborn stains or fine debris, which is convenient for the fixed semi-ring to better clean the sundries. The combination of the reciprocating screw and the sliding block enables the fixed semi-ring to perform reciprocating cleaning, expanding the cleaning range and improving the cleaning efficiency. By squeezing the triggering member with the top block to pass the cleaning agent into the sliding block to infiltrate the fixed semi-ring, the cleaning ability is enhanced, and the sundries in the working area can be more thoroughly removed, keeping the equipment clean, extending the service life of the equipment, and at the same time improving the spot welding quality and reducing the welding defects caused by sundries.

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0023] Example 1: As Figures 1 to 10 shown, an automotive part processing device according to an embodiment of the present invention includes a spot welding machine body 1. A first hydraulic cylinder 11 is fixedly connected to the upper end of the spot welding machine body 1. The output end of the first hydraulic cylinder 11 is fixedly connected to an upper spot welding head 12. A lower spot welding head 13 is fixedly connected to one side of the spot welding machine body 1. A base plate 2 is fixedly connected to one side of the spot welding machine body 1. A second hydraulic cylinder 21 is fixedly connected to the upper surface of the base plate 2. A limiting component is arranged at the output end of the second hydraulic cylinder 21. The limiting component includes a fixed plate 22 fixedly connected to the output end of the second hydraulic cylinder 21. A connecting plate 26 is rotatably arranged on one side of the fixed plate 22. A pressing block 28 is elastically connected inside the connecting plate 26; A rotating shaft 23 is rotatably connected inside the fixed plate 22. Connecting rods 25 are fixedly connected to both ends of the rotating shaft 23. An auxiliary part is arranged inside the connecting rods 25. The auxiliary part includes a cross bar 218 slidably arranged in the middle of the two connecting rods 25. A fixed frame 220 is fixedly connected to the lower surface of the cross bar 218. A rotating roller 222 is rotatably arranged inside the fixed frame 220.

[0024] Specifically, the existing spot welding machines have obvious disadvantages in the actual use process. Currently, their operation mostly relies on the staff to hold the sorted wire harness terminals for welding. During the holding process, it is inevitable for the staff to have some physiological tremors. Even if the tremor amplitude is extremely small, it will have an adverse effect on the welding quality. Because the welding of wire harness terminals requires extremely high precision, a slight tremor may cause the contact position between the wire harness terminal and the spot welding head to shift, resulting in inaccurate welding positions, and then errors such as virtual welding and missed welding may occur. This will not only cause the wire harness terminals to be welded insecurely, affecting the overall electrical conductivity of the wire harness, but also may cause subsequent automotive circuit failures, increasing the defective rate and rework cost of the product, reducing production efficiency, and being unfavorable for large-scale and high-quality production of automotive parts; Therefore, the present invention solves the above problems by setting the above structure. First, when the spot welding equipment works, the first hydraulic cylinder 11 drives the upper spot welding head 12 to move downward, and cooperates with the lower spot welding head 13 to perform spot welding on the workpiece. However, before spot welding, the second hydraulic cylinder 21 is started. The second hydraulic cylinder 21 pushes the limiting component to move to a suitable position. The fixed plate 22 moves with the output end of the second hydraulic cylinder 21, driving the connecting plate 26 and the pressing block 28 to approach the automotive wire harness terminal. The pressing block 28 elastically contacts the workpiece to achieve preliminary limiting. During the sliding process of the rotating shaft 23, it rotates to adjust the connecting rod 25 to be parallel to the bottom plate 2. Then the cross bar 218 slides passively in the middle of the connecting rod 25, driving the fixed frame 220 to move above the workpiece. The rotating roller 222 contacts the automotive wire harness terminal for secondary limiting. At the same time, during the passive sliding process of the rotating roller 222, it will adhesively clean the upper surface of the wire harness terminal, and then perform spot welding work. During the spot welding process, the stability of spot welding is improved. This spot welding equipment can effectively fix the automotive wire harness terminal through the cooperation of the limiting component and the auxiliary component, prevent the automotive wire harness terminal from shifting during spot welding, improve the spot welding accuracy. The elastic connection of the pressing block 28 can avoid damaging the automotive wire harness terminal. The design of the rotating roller 222 can perform secondary limiting while cleaning the surface of the automotive wire harness terminal, ensuring the stability of spot welding quality. The overall structure is reasonable, the operation is convenient, the production efficiency and product qualification rate can be improved, and the scrap rate can be reduced; It solves the problem that the contact position between the wire harness terminal and the spot welding head shifts due to the inevitable tremors of the staff.

[0025] Such as Figure 3 and Figure 8 As shown in the figure, a rack plate 210 is fixedly connected to the upper surface of the bottom plate 2 of this embodiment. Gears 24 are fixedly connected to both ends of the rotating shaft 23. The gears 24 rotate along the rack plate 210. An auxiliary plate 211 is fixedly connected to one side of the rack plate 210. A cleaning component is arranged on the upper surface of the bottom plate 2. The cleaning component includes two positioning frames 3 fixedly connected to the upper surface of the bottom plate 2. The same hook plate 31 is slidably connected in the two positioning frames 3. A fixed semi-ring 35 is slidably arranged inside the hook plate 31.

[0026] Specifically, after the second hydraulic cylinder 21 is activated, it will push the fixed plate 22 forward. During the movement of the fixed plate 22, the gears 24 at both ends thereof will rotate along the rack plate 210. The rotation of the gears 24 indirectly drives the connecting plate 26 to rotate so that it is parallel to the bottom plate 2. Then the gears 24 will move along the auxiliary plate 211 without teeth. At this time, the connecting plate 26 deforms and extends the pressing block 28 to limit the wire harness terminal. In addition, during the retraction process of the second hydraulic cylinder 21, it will cooperate with the cleaning assembly to clean the rotating roller 222 in the fixed frame 220 through the fixed half-ring 35 slidably arranged in the hook plate 31, achieving a more ingenious cooperation work, improving the fixing effect while also improving the welding quality.

[0027] As Figure 5 and Figure 6 As shown, the limiting component of this embodiment further includes two pressing plates 29 fixedly connected to the upper surface of the bottom plate 2. Fixing grooves 27 are provided at the positions of the connecting plate 26 corresponding to the two pressing plates 29. Two groups of connecting grooves 213 are provided inside the connecting plate 26. Each group of connecting grooves 213 has two, and a first compression spring 214 is fixedly connected in each connecting groove 213. The two first compression springs 214 are fixedly connected to the same conical block 215. Fixed rods 216 are fixedly connected to the lower surfaces of the two conical blocks 215, and the same pressing block 28 is fixedly connected to the bottom ends of the two fixed rods 216.

[0028] Specifically, during the working process of the limiting component, when the second hydraulic cylinder 21 pushes the connecting plate 26 towards the workpiece, the fixing groove 27 on the connecting plate 26 will gradually approach the pressing plate 29 fixedly connected to the upper surface of the bottom plate 2. As it moves, the pressing plate 29 will enter the fixing groove 27 and exert a squeezing effect on the conical block 215 in the fixing groove 27. Since two groups of connecting grooves 213 are provided inside the connecting plate 26 and the first compression springs 214 in each group of connecting grooves 213 are initially in a certain state, the squeezing of the pressing plate 29 causes the conical block 215 in the connecting groove 213 to be subjected to a squeezing force, and the first compression spring 214 is compressed. The conical block 215 moves under the pressure, driving the fixed rod 216 fixedly connected to its lower surface and the pressing block 28 at the bottom end of the fixed rod 216 to move together. When the pressing block 28 moves to contact the automotive wire harness terminal, under the elastic force of the first compression spring 214, the pressing block 28 will tightly press the automotive wire harness terminal, thereby realizing the limiting and fixing of the workpiece and ensuring that the workpiece maintains a stable position during spot welding. By using the cooperation of the pressing plate 29 and the fixing groove 27 and the elastic action of the first compression spring 214, the pressing block 28 can adaptively adjust the pressing force on the automotive wire harness terminal, ensuring both the reliability of the limit and avoiding damage to the workpiece due to excessive pressure. At the same time, the structure is simple, the operation is convenient, it can effectively improve the accuracy and stability of spot welding operations, and improve product quality and production efficiency.

[0029] AsFigure 6 As shown, the cross-section of the pressing block 28 in this embodiment is convex. The pressing block 28 is used for limiting the wire harness terminal. The pressing block 28 is a metal block. After the second hydraulic cylinder 21 pushes the connecting plate 26 to rotate and the gear 24 moves to the auxiliary plate 211, when the connecting plate 26 moves linearly along the bottom plate 2, the extrusion plate 29 is passively inserted into the fixing groove 27 to extrude the tapered block 215, so that the pressing block 28 extends out of the connecting plate 26.

[0030] Specifically, when limiting the wire harness terminal, the second hydraulic cylinder 21 first pushes the connecting plate 26 to rotate, so that the gear 24 moves to the auxiliary plate 211. At this time, the movement mode of the connecting plate 26 changes to linear movement along the bottom plate 2. As the connecting plate 26 moves, the extrusion plate 29 fixed on the bottom plate 2 will gradually be inserted into the fixing groove 27 opened at the corresponding position of the connecting plate 26. The extrusion plate 29 exerts extrusion on the tapered block 215 in the fixing groove 27, causing the tapered block 215 to move in the connecting groove 213. And the tapered block 215 is connected to the pressing block 28 through the fixing rod 216, thereby pushing the pressing block 28 to extend out of the connecting plate 26. Since the cross-section of the pressing block 28 is convex and it is a metal block, it can stably limit the wire harness terminal and fix it in a proper position, which is convenient for subsequent spot welding operation. Through the cooperation of components such as the second hydraulic cylinder 21, the gear 24, the connecting plate 26, and the extrusion plate 29, the automatic extension and limitation of the pressing block 28 are realized. The pressing block 28 made of metal is firm and durable. The convex cross-section design can better fit the wire harness terminal, improve the limiting effect, ensure the spot welding accuracy, reduce the displacement of the wire harness terminal during the spot welding process, and improve the product quality and production efficiency.

[0031] As Figure 3 and Figure 4 shown, two stoppers 212 are fixedly connected to the upper surface of the bottom plate 2 in this embodiment. Push rods 219 are fixedly connected to both ends of the cross bar 218. A sliding groove 217 is opened in the middle of each connecting rod 25. The push rod 219 slides along the sliding groove 217. A spring 221 is fixedly connected between the push rod 219 and the inner wall of the connecting rod 25.

[0032] Specifically, when the second hydraulic cylinder 21 drives the fixed plate 22 to move, the gear 24 will first rotate along the rack plate 210, driving the connecting plate 26 and the connecting rod 25 to rotate. When the gear 24 moves to the auxiliary plate 211, the connecting rod 25 is parallel to the bottom plate 2, and the connecting rod 25 starts to slide. During the sliding process of the connecting rod 25, the stopper 212 blocks the push rod 219, the push rod 219 squeezes the spring 221, and the push rod 219 drives the fixed frame 220 to slide passively, driving the rotating roller 222 to adhere to the stains on the surface of the wire harness terminal, achieving the effect of improving the spot welding quality.

[0033] Embodiment 2: As Figures 1 to 10As shown, compared with the first comparative example, another implementation of the present invention is as follows: The cleaning component further includes a connecting spring 314 fixedly connected inside the positioning frame 3. An expansion rod 315 is arranged inside the connecting spring 314, and the expansion rod 315 is used for limiting the connecting spring 314. A positioning groove 32 is formed on one side of the hook plate 31. A reciprocating screw 33 is rotatably connected inside the positioning groove 32. A sliding block 34 is slidably connected to the circumferential surface of the reciprocating screw 33. A fixed semi-ring 35 is fixedly connected to one side of the sliding block 34, and the fixed semi-ring 35 abuts against the rotating roller 222. A storage box 37 is fixedly connected to the upper surface of the hook plate 31. A triggering member is arranged inside the storage box 37. A top block 36 is fixedly connected to the upper surface of the sliding block 34. A limiting hole 313 is formed on the upper surface of the top block 36. The top block 36 presses the triggering member to introduce the cleaning agent inside the storage box 37 into the sliding block 34 to soak the fixed semi-ring 35.

[0034] Specifically, after the working process of the spot welding device is completed, the connecting plate 26 is retracted by the second hydraulic cylinder 21 and rotates along the rack plate 210 again. During the rotation process, the fixed block presses the hook, causing the hook plate 31 to slide inside the positioning frame 3. The connecting spring 314 inside the positioning frame 3 provides buffering for the movement of the hook plate 31. At the same time, the expansion rod 315 plays a role in limiting the connecting spring 314 to prevent the connecting spring 314 from shifting during the telescoping process and ensure the stability of the movement of the hook plate 31. The hook plate 31 is driven to slide passively, causing the hook plate 31 to pass through the two connecting rods 25 and approach the rotating roller 222 on the side close to the fixed frame 220. The reciprocating screw 33 inside the positioning groove 32 rotates under the action of the built-in motor. Since the sliding block 34 is slidably connected to the reciprocating screw 33, the sliding block 34 will perform a reciprocating linear motion along the reciprocating screw 33, thereby driving the fixed semi-ring 35 to move. The fixed semi-ring 35 abuts against the rotating roller 222, and the sundries on the rotating roller 222 and in the working area can be cleaned during the movement. During the movement of the sliding block 34, the top block 36 fixedly connected to its upper surface will successively press the triggering member inside the storage box 37. After the triggering member is pressed, the cleaning agent inside the storage box 37 will be introduced into the sliding block 34 through the channel, and then soak the fixed semi-ring 35. The cleaning agent can enhance the cleaning effect of the fixed semi-ring 35 on the sundries, soften and dissolve some stubborn stains or fine debris, facilitating the fixed semi-ring 35 to better clean the sundries. The combination of the reciprocating screw 33 and the sliding block 34 enables the fixed semi-ring 35 to perform reciprocating cleaning, expanding the cleaning range and improving the cleaning efficiency. By pressing the triggering member with the top block 36 to introduce the cleaning agent into the sliding block 34 to soak the fixed semi-ring 35, the cleaning ability is enhanced, the sundries in the working area can be more thoroughly removed, the equipment can be kept clean, the service life of the equipment can be extended, and at the same time, the spot welding quality can be improved, reducing welding defects caused by sundries.

[0035] Such as Figure 10As shown in the figure, the trigger part of this embodiment includes a number of auxiliary slots 311 opened inside the storage box 37. Positioning holes 312 are opened on the inner wall of the auxiliary slots 311. A second compression spring 39 is fixedly connected to the top wall of the auxiliary slots 311. The bottom end of the second compression spring 39 is fixedly connected to an auxiliary block 38. A through connection hole 310 is opened inside the auxiliary block 38. After the top block 36 presses the auxiliary block 38, the auxiliary block 38 presses the second compression spring 39 upward. The auxiliary block 38 moves upward. The connection hole 310 inside the auxiliary block 38 aligns with the positioning hole 312, so that the cleaning agent flows into the auxiliary block 38 along the positioning hole 312 and then enters the limiting hole 313 of the top block 36 through the auxiliary block 38.

[0036] Specifically, when the cleaning component works, when the sliding block 34 moves to drive the top block 36 to move to press the auxiliary block 38 in the storage box 37, the auxiliary block 38 receives an upward acting force from the top block 36. Since the top of the auxiliary block 38 is connected to the top wall of the auxiliary slot 311 through the second compression spring 39, the auxiliary block 38 will press the second compression spring 39 upward, and the second compression spring 39 is compressed. As the auxiliary block 38 continues to move upward, the through connection hole 310 opened inside the auxiliary block 38 will align with the positioning hole 312 on the inner wall of the auxiliary slot 311. At this time, under the action of the built-in pressure pump in the storage box 37, the cleaning agent flows into the connection hole 310 inside the auxiliary block 38 along the positioning hole 312, and then enters the limiting hole 313 of the top block 36 through the connection hole 310, and then enters the sliding block 34, and finally wets the fixed half-ring 35, enhancing the cleaning effect of the fixed half-ring 35 on sundries; Using the extrusion of the top block 36 to move the auxiliary block 38, accurately control the flow path of the cleaning agent. Through the elastic action of the second compression spring 39, it can ensure that the auxiliary block 38 resets when not being extruded, realize the automatic control of the cleaning agent flow, provide the cleaning agent in time when cleaning is needed, enhance the cleaning ability, effectively remove sundries and stains in the working area, keep the equipment clean, improve the spot welding quality and the stability of the equipment operation, and extend the service life of the equipment.

[0037] Working principle: First, when the spot welding equipment works, the first hydraulic cylinder 11 drives the upper spot welding head 12 to move downward, cooperating with the lower spot welding head 13 to perform spot welding on the workpiece. However, before spot welding, the second hydraulic cylinder 21 is started. After the second hydraulic cylinder 21 is started, it will push the fixed plate 22 to move forward. During the movement of the fixed plate 22, the gears 24 at both ends thereof will rotate along the rack plate 210. The rotation of the gears 24 indirectly drives the connecting plate 26 to rotate so that it is parallel to the bottom plate 2. Then the gears 24 will move along the auxiliary plate 211 without teeth. At this time, the connecting plate 26 deforms and extends the pressing block 28 to perform the limiting work on the wire harness terminal. In addition, during the retraction process of the second hydraulic cylinder 21, it will cooperate with the cleaning component to clean the rotating roller 222 in the fixed frame 220 through the fixed semi-ring 35 slidably arranged in the hook plate 31, achieving a more ingenious cooperative work, improving the fixing effect and also improving the welding quality; In addition, during the working process of the limiting component, when the second hydraulic cylinder 21 pushes the connecting plate 26 to move towards the workpiece, the fixing groove 27 on the connecting plate 26 will gradually approach the pressing plate 29 fixedly connected to the upper surface of the bottom plate 2. With the movement, the pressing plate 29 will enter the fixing groove 27 and exert an extrusion effect on the conical block 215 in the fixing groove 27. Since two connecting grooves 213 are opened inside the connecting plate 26 and the first compression springs 214 in each group of connecting grooves 213 are initially in a certain state, the extrusion of the pressing plate 29 causes the conical block 215 in the connecting groove 213 to be subjected to an extrusion force, and the first compression spring 214 is compressed. The conical block 215 moves under the pressure, driving the fixing rod 216 fixedly connected to its lower surface and the pressing block 28 at the bottom end of the fixing rod 216 to move together. When the pressing block 28 moves to contact the automotive wire harness terminal, under the elastic force of the first compression spring 214, the pressing block 28 will tightly press the automotive wire harness terminal, thereby realizing the limiting and fixing of the workpiece, ensuring that the workpiece maintains a stable position during spot welding. By using the cooperation between the pressing plate 29 and the fixing groove 27 and the elastic action of the first compression spring 214, the pressing block 28 can adaptively adjust the pressing force on the automotive wire harness terminal, which not only ensures the reliability of the limit but also avoids damaging the workpiece due to excessive pressure. At the same time, the structure is simple, the operation is convenient, it can effectively improve the accuracy and stability of the spot welding operation, and improve the product quality and production efficiency; Moreover, when the second hydraulic cylinder 21 drives the fixed plate 22 to move, the gears 24 will first rotate along the rack plate 210, driving the connecting plate 26 and the connecting rod 25 to rotate. When the gears 24 move to the auxiliary plate 211, the connecting rod 25 is parallel to the bottom plate 2, and the connecting rod 25 will slide. During the sliding process of the connecting rod 25, the stop block 212 blocks the push rod 219, the push rod 219 squeezes the spring 221, and the push rod 219 drives the fixed frame 220 to perform a passive slide, driving the rotating roller 222 to adhere to the stains on the surface of the wire harness terminal, achieving the effect of improving the spot welding quality; Finally, after the working process of the spot welding equipment is completed, the connecting plate 26 is retracted through the second hydraulic cylinder 21 and rotates along the rack plate 210 again. During the rotation process, the fixed block presses the hook, causing the hook plate 31 to slide within the positioning frame 3. The connecting spring 314 within the positioning frame 3 provides buffering for the movement of the hook plate 31. At the same time, the telescopic rod 315 plays a limiting role on the connecting spring 314 to prevent the connecting spring 314 from shifting during the telescopic process, ensuring the stability of the movement of the hook plate 31; The hook plate 31 is forced to slide, causing the hook plate 31 to pass through the two connecting rods 25 and approach the rotating roller 222 on the side close to the fixed frame 220. The reciprocating screw 33 within the positioning groove 32 rotates under the action of the built-in motor. Since the sliding block 34 is slidably connected to the reciprocating screw 33, the sliding block 34 will perform reciprocating linear motion along the reciprocating screw 33, thereby driving the fixed semi-ring 35 to move. The fixed semi-ring 35 abuts against the rotating roller 222, and during the movement, debris on the rotating roller 222 and within the working area can be cleared away; The top block 36 fixedly connected to its upper surface will successively press the triggering parts within the storage box 37. After the triggering parts are pressed, the cleaning agent within the storage box 37 will pass through the channel into the sliding block 34, thereby soaking the fixed semi-ring 35. The cleaning agent can enhance the cleaning effect of the fixed semi-ring 35 on debris, soften and dissolve some stubborn stains or fine debris, facilitating the fixed semi-ring 35 to better clean the debris. The combination of the reciprocating screw 33 and the sliding block 34 enables the fixed semi-ring 35 to perform reciprocating cleaning, expanding the cleaning range and improving the cleaning efficiency. By the top block 36 pressing the triggering parts to introduce the cleaning agent into the sliding block 34 to soak the fixed semi-ring 35, the cleaning ability is enhanced, the debris in the working area can be more thoroughly removed, the equipment can be kept clean, the service life of the equipment can be extended, and at the same time, the spot welding quality can be improved, reducing welding defects caused by debris; Specifically, the triggering part is that when the sliding block 34 moves to drive the top block 36 to move to press the auxiliary block 38 within the storage box 37, the auxiliary block 38 will receive an upward acting force from the top block 36. Since the top of the auxiliary block 38 is connected to the top wall of the auxiliary groove 311 through the second compression spring 39, the auxiliary block 38 will upwardly compress the second compression spring 39, and the second compression spring 39 is compressed. As the auxiliary block 38 continues to move upward, the through connection hole 310 opened within the auxiliary block 38 will align with the positioning hole 312 on the inner wall of the auxiliary groove 311. At this time, the cleaning agent within the storage box 37, under the action of the built-in pressure pump, flows along the positioning hole 312 into the connection hole 310 inside the auxiliary block 38, and then enters the limiting hole 313 of the top block 36 through the connection hole 310, and then enters the sliding block 34, and finally soaks the fixed semi-ring 35, enhancing the cleaning effect of the fixed semi-ring 35 on debris.
