Description

Technical Field

[0001] This invention relates to the field of welding fixture technology, and in particular to a welding fixture for sensor processing. Background Technology

[0002] In the sensor manufacturing process, in order to achieve mechanical fixation of components such as sensitive elements, electrodes, and packaging shells, and to improve the overall integrity of the sensor structure and the stability of signal transmission, welding equipment is usually used to weld some components. However, with the large-scale application of technologies such as PDV (plasma vapor deposition), CVD (chemical vapor deposition), DRY (dry process), and ETCH (etching technology) in sensor production, sensors are rapidly iterating towards miniaturization, high precision, and high reliability. The shortcomings of traditional welding methods (such as manual welding and general fixture welding) such as insufficient positioning accuracy and unstable clamping are gradually becoming apparent. Therefore, in order to improve the stability and positioning accuracy of sensors during the welding process, welding fixtures specifically adapted to the precision machining characteristics of sensors have emerged. However, existing welding fixtures used for clamping sensor workpieces are mostly purely mechanical structures, relying solely on preset mechanical limits or manual experience to control the clamping force. They cannot adaptively adjust the clamping force of the welding fixture according to the characteristics of the workpiece. For example, some sensor components that need to be welded may have functional layers that have decreased rigidity, weakened stress resistance, and reduced pressure resistance after being processed by processes such as PDV (plasma vapor deposition) and CVD (chemical vapor deposition) during the production process. If existing welding fixtures use a large clamping force to clamp and fix such workpieces, it is easy to cause the PDV / CVD deposited functional film on the workpiece to fall off or crack, directly damaging the sensor's sensitive unit and signal transmission path, resulting in a decrease in sensor detection accuracy. At the same time, excessive clamping force can also easily damage the workpiece surface, reducing the overall aesthetics of the workpiece. On the other hand, if the clamping force is too small, the workpiece is prone to displacement and loosening during the welding process, leading to misalignment and incomplete welding of the weld joint. Therefore, we propose a welding fixture for sensor processing to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to solve the problems mentioned in the background art by providing a welding fixture for sensor processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A welding fixture for sensor processing includes a main body, two mounting seats fixedly mounted on the main body, a driving component on the main body, a clamping component on each of the two mounting seats, and an adjustment component on each of the two mounting seats. The drive assembly includes support rods fixedly installed on the inner walls of two mounting bases respectively, rotating gears rotatably installed on both support rods, incomplete gears rotatably installed on both support rods, sliding components slidably installed on both support rods, and conical cylinders fixedly installed on both sliding components; Both clamping assemblies include multiple telescopic cylinders, which are slidably mounted on corresponding mounting bases. A driving component is shared between the multiple telescopic cylinders, and a limiting mechanism is shared between the multiple telescopic cylinders. Both of the aforementioned adjustment components include multiple positioning plates, and the positioning plates are fixedly installed on the telescopic ends of the corresponding telescopic cylinders. Clamping plates are slidably installed on each positioning plate, and adjustment mechanisms are installed on each positioning plate.

[0005] Compared with existing technologies, the advantages of this invention are: 1. In the process of clamping the workpiece to be welded, the present invention, through the cooperation of the drive component and the clamping component, can adaptively adjust the clamping force of the multiple clamping plates driven by the device to the workpiece according to the required safe clamping force of the workpiece to be welded. This helps to improve the clamping stability of the device for different workpieces. At the same time, after the corresponding multiple clamping plates have clamped the workpiece, the position of the multiple clamping plates can be limited by the locking mechanism, which helps to improve the stability of the device in continuously clamping and fixing the workpiece.

[0006] 2. During the workpiece clamping process, the present invention can indirectly realize the automatic detection of the wear degree of the clamping plate through the cooperation of the drive component and the adjustment mechanism. When the wear of the clamping plate continues to increase and its clamping force on the workpiece gradually decreases, the clamping force of the clamping plate on the workpiece can be increased in a timely and adaptive manner through the cooperation of the transmission component and the pushing component. This can effectively improve the effect of continuous cooperation of multiple clamping plates in clamping and fixing the workpiece, and help to further improve the continuous clamping and fixing effect and stability of the equipment for welding workpieces.

[0009] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0010] Reference Figures 1-15 A welding fixture for sensor processing includes a main body 1, two mounting seats 2 fixedly mounted on the main body 1, a drive assembly 3 on the main body 1, a clamping assembly 4 on each of the two mounting seats 2, and an adjustment assembly 5 on each of the two mounting seats 2.

[0011] The drive assembly 3 includes support rods 36 fixedly mounted on the inner walls of two mounting bases 2, rotating gears 37 rotatably mounted on each support rod 36, incomplete gears 38 rotatably mounted on each support rod 36, sliding members 39 slidably mounted on each support rod 36, and conical cylinders 310 fixedly mounted on each sliding member 39 (in conjunction with...). Figure 3 and Figure 4 It can be seen that both support rods 36 are equipped with retaining rings that cooperate with the corresponding pushing parts 39. In the initial state, the two retaining rings can respectively limit the position of the corresponding pushing parts 39 and the conical cylinder 310. When the equipment is running, the thrust that drives the pushing parts 39 and the conical cylinder 310 to move upward disappears. When the pushing parts 39 and the conical cylinder 310 move downward under their own gravity, the two retaining rings can limit the downward movement position of the corresponding pushing parts 39 and the conical cylinder 310.

[0012] A servo motor 31 is fixedly installed on the main body 1 of the equipment. An electric telescopic rod 32 is fixedly installed on the drive end of the servo motor 31. A drive gear 33 is fixedly installed on the telescopic end of the electric telescopic rod 32. A drive gear 34 is fixedly installed on the telescopic end of the electric telescopic rod 32. A push plate 35 is fixedly installed on the telescopic end of the electric telescopic rod 32.

[0013] Both clamping assemblies 4 include multiple telescopic cylinders 44, which are slidably mounted on the corresponding mounting bases 2. A drive component is installed between each of the multiple telescopic cylinders 44, and a limit mechanism is installed between each of the multiple telescopic cylinders 44.

[0014] Both adjustment components 5 include multiple positioning plates 51, and the positioning plates 51 are fixedly installed on the telescopic ends of the corresponding telescopic cylinders 44. Clamping plates 52 are slidably installed on the positioning plates 51 (in conjunction with...). Figure 13 It can be seen that each positioning plate 51 has a sliding groove for sliding the clamping plate 52, and each positioning plate 51 is equipped with an adjustment mechanism.

[0015] Both limiting mechanisms include multiple arc-shaped grooves 45, which are formed on corresponding incomplete gears 38. A round rod 46 is slidably mounted on each arc-shaped groove 45, and a plate 47 is fixedly mounted on each round rod 46. Two push blocks (shown in the figure but not labeled) are fixedly mounted on each plate 47. Figure 9 As can be seen from the image, each push block on one side is fixedly equipped with a telescopic rod 48, and each telescopic cylinder 44 is fixedly equipped with a return spring 412. One end of each return spring 412 is fixedly installed on the corresponding fixed end of the telescopic cylinder 44. Each fixed end of each telescopic cylinder 44 is fixedly equipped with two telescopic rods 49. Each of the two telescopic rods 49 is fixedly installed with a positioning plate 410. Each positioning plate 410 is fixedly equipped with a push rod 411 at its lower end. Each push rod 411 is fixedly connected to the corresponding telescopic rod 48. Each positioning plate 410 is equipped with a locking component.

[0016] When the device needs to weld the workpieces that make up the sensor (hereinafter referred to as the workpieces to be welded), the workpieces to be welded are first placed between the corresponding clamping plates 52, and then the electric telescopic rod 32 is started. At this time, the operation of the electric telescopic rod 32 will first drive the second drive gear 34 to move upward. When the second drive gear 34 meshes with the two incomplete gears 38, the electric telescopic rod 32 is stopped and the servo motor 31 is started.

[0017] When the second drive gear 34 meshes with the two incomplete gears 38 and the servo motor 31 is running, the operation of the servo motor 31 will only drive the two incomplete gears 38 to rotate through the cooperation of the electric telescopic rod 32 and the second drive gear 34. At this time, the rotation of the two incomplete gears 38 can adaptively adjust the horizontal position of the positioning plate 410 according to the safety clamping force required by the workpiece to be welded.

[0018] Based on the material mechanical parameters of the part (i.e., the workpiece) (such as the compressive strength of ceramics, the yield strength of thin-walled metals) and the contact area (the contact dimensions between the clamping surface and the part), the formula (F) can be used to determine the appropriate parameters. 安全 =P 允许 ×S 接触 Calculate the maximum allowable contact pressure of the part, and then convert it into the safe clamping force required during the welding process. This will give you an idea of ​​the safe clamping force required for the part during welding. For example, if the compressive strength of a ceramic base is 200MPa and the contact area between the clamp and the base is 0.01cm², the maximum allowable contact pressure of the part is calculated to be 20N according to the formula. Therefore, before clamping the workpiece to be welded, the safe clamping force required for this type of workpiece can be calculated based on the characteristics of the workpiece (such as compressive strength) and the contact area between the clamping plate 52 and the workpiece.

[0019] When the servo motor 31 cooperates with the drive component to drive the corresponding multiple telescopic cylinders 44, positioning plates 51, and clamping plates 52 to move closer to each other, and the corresponding multiple clamping plates 52 are in contact with the surface of the workpiece to be welded, the servo motor 31 cooperates with the drive component to drive the telescopic cylinders 44 to move closer to each other. Because the workpiece to be welded limits the position of the telescopic end of the corresponding telescopic cylinder 44 through the cooperation of the corresponding clamping plates 52 and positioning plates 51, the operation of the servo motor 31 will only drive the fixed end of the telescopic cylinder 44 to move closer to each other and compress the corresponding return spring 412. The elastic force generated by the compression of the return spring 412 will be transmitted to the workpiece to be welded through the cooperation of the telescopic end of the corresponding telescopic cylinder 44, positioning plate 51, and clamping plate 52. Therefore, the clamping force of the corresponding multiple clamping plates 52 on the workpiece to be welded is essentially the elastic force generated when the corresponding return spring 412 is compressed, and the two are exactly equal in magnitude. According to Hooke's Law, F = k × x (where F is the spring force, k is the spring stiffness, and x is the spring compression), and since the spring stiffness k of the return spring 412 is a fixed value, the spring force F of the return spring 412 is linearly positively correlated with its compression x. That is, the greater the compressible deformation of the return spring 412, the greater the clamping force generated by the clamping plate 52 on the workpiece to be welded, and vice versa. Therefore, when the required safe clamping force for the workpiece to be welded is large, and the clamping force of multiple clamping plates 52 needs to be increased accordingly, the servo motor 31 is started in the forward direction. At this time, the operation of the servo motor 31 will drive the corresponding multiple round rods 46 to move away from each other through the cooperation of the electric telescopic rod 32, the second drive gear 34, the two incomplete gears 38, and the multiple arc grooves 45. Figure 7 and Figure 8 In the indicated direction, the driving rod 46 drives the corresponding plate 47, the two push blocks, and the telescopic rod 48 to move to the right. During this process, the thrust applied by the telescopic rod 48 to the corresponding push rod 411 can push the push rod 411 and the corresponding positioning plate 410 to move to the right together. This can adaptively increase the operation of the subsequent servo motor 31, drive the clamping plates 52 to move closer to each other to clamp the workpiece to be welded, and compress the corresponding multiple return springs 412. That is, adaptively increase the clamping force of the subsequent multiple clamping plates 52 in coordination with the workpiece to be welded.

[0020] Conversely, if the required clamping force for the workpiece to be welded is small, and the clamping force of the corresponding multiple clamping plates 52 needs to be appropriately reduced, the servo motor 31 is reversed. At this time, the operation of the servo motor 31, in cooperation with the limit mechanism, will drive the positioning disk 410 to move to the left (e.g., Figure 7 and Figure 8(As shown in the direction), the subsequent servo motor 31 is adapted to shorten the operation, driving the clamping plates 52 to move closer together to clamp the workpiece to be welded. This reduces the compression of the corresponding multiple return springs 412, i.e., the clamping force of the corresponding multiple clamping plates 52 on the workpiece to be welded. This not only ensures the stability of the workpiece clamping by the corresponding multiple clamping plates 52, but also helps to improve the clamping effect of the workpiece and improve the welding effect of the workpiece using existing welding equipment.

[0021] Reference Figures 3-9 Both drive components include multiple arc-shaped grooves 41, and these grooves 41 are formed on the corresponding rotating gears 37. Brake rods 42 are slidably mounted on each arc-shaped groove 41. A connecting frame 43 is fixedly mounted between the brake rods 42 and the corresponding telescopic cylinders 44 (and combined with...). Figure 3 It can be seen that the main body 1 of the equipment has multiple sliding holes for the connecting frame 43 to slide, which facilitates the sliding of the connecting frame 43 and also helps to improve the stability of the horizontal sliding of the connecting frame 43 under force.

[0022] Each of the multiple engaging components includes a warning rod 416, which is slidably mounted on the corresponding positioning plate 410. Each telescopic cylinder 44 has a uniformly distributed arc-shaped locking rod 414 fixedly mounted on its telescopic end. Each telescopic cylinder 44 has a fixedly mounted drive rod 415 that cooperates with the corresponding warning rod 416 on its telescopic end. Each positioning plate 410 has a uniformly distributed annular locking groove 413.

[0023] When the servo motor 31, electric telescopic rod 32, and limit mechanism work together to adaptively adjust the position of the positioning plate 410 according to the required safety clamping force of the workpiece to be welded, first stop the operation of the servo motor 31, and then restart the electric telescopic rod 32. At this time, the operation of the electric telescopic rod 32 will drive the drive gear 1 33, drive gear 2 34, and push plate 35 to move downward (e.g., Figure 4 (in the direction shown) until the drive gear 33 meshes with the two rotating gears 37.

[0024] When the drive gear 33 meshes with the two rotating gears 37, the operation of the electric telescopic rod 32 is stopped, and the servo motor 31 is restarted. At this time, the operation of the servo motor 31 will drive the two rotating gears 37 to rotate only through the cooperation of the electric telescopic rod 32 and the drive gear 33. The rotation of the rotating gears 37 will drive the corresponding brake rods 42 to move closer to each other through the driving force applied to the corresponding brake rods 42 by the corresponding arc grooves 41. When the corresponding brake rods 42 move closer to each other, the driving force applied to the corresponding telescopic cylinders 44 by the corresponding connecting frame 43 can drive the corresponding telescopic cylinders 44 to move closer to each other together.

[0025] Once the corresponding telescopic cylinders 44 are subjected to force, the corresponding positioning plates 51 and clamping plates 52 move closer to each other. After the clamping plates 52 contact the surface of the workpiece to be welded, the fixed ends of the multiple telescopic cylinders 44 can be driven to move closer to each other by the continuous operation of the servo motor 31, compressing the corresponding return springs 412. During this process, the positioning plate 410 can be driven to move continuously together by the cooperation of the telescopic cylinders 44 and the corresponding two telescopic rods 49. Figure 8 , Figure 9 In the indicated direction, the drive positioning disk 410 continues to move to the left until the multiple locking rods 414 and drive rod 415 on the telescopic end of the telescopic cylinder 44 are locked into the corresponding slots 413. The reset spring 412 is compressed to the preset compression amount, that is, the corresponding multiple clamping plates 52 cooperate with the clamping force of the workpiece to be welded. When the required safe clamping force of the workpiece to be welded is reached, the operation of the servo motor 31 can be stopped.

[0026] Simultaneously, when the workpiece to be welded cooperates with the positioning plate 51 through the corresponding clamping plate 52, the telescopic end of the corresponding telescopic cylinder 44 is indirectly fixed, and the positioning plate 410 is continuously moved to the left under force (e.g. Figure 9 As the drive rod 415 gradually inserts into the corresponding slot 413, the driving force applied by the inclined surface of the drive rod 415 to the lower end ball of the corresponding warning rod 416, and the limiting effect of the positioning plate 410 on the moving direction of the corresponding warning rod 416, can drive the warning rod 416 to move upward until the positioning plate 410 is in contact with the telescopic end of the corresponding telescopic cylinder 44, the corresponding drive rod 415 is fully inserted into the corresponding slot 413, and the upper end of the warning rod 416 moves above the mounting base 2 (as shown in the direction). Figure 5 (As shown in the direction), this allows operators to easily observe the upward movement of the warning bar 416 on the mounting base 2 to determine whether the clamping force of the corresponding multiple clamping plates 52 on the workpiece meets the required clamping force for the workpiece to be welded. This helps to further ensure that the equipment can adaptively adjust the clamping force on the workpiece according to the required safe clamping force, and further improve the clamping and fixing effect and clamping stability of the equipment for different workpieces to be welded.

[0027] Furthermore, when the corresponding multiple locking rods 414 and drive rods 415 are fully inserted into the corresponding slots 413, and the corresponding clamping plates 52 begin to clamp and fix the workpiece to be welded, the compression amount of the corresponding return spring 412 can be limited through the cooperation of the multiple locking rods 414, drive rods 415, and corresponding slots 413. This indirectly limits the position of the corresponding clamping plates 52, preventing the workpiece from shifting due to vibration or other factors during the welding process using existing welding equipment. This prevents the clamping plates 52 from shifting by compressing the corresponding return spring 412, thus reducing the clamping stability of the equipment. Therefore, by limiting the compression amount of the return spring 412 through the cooperation of the multiple locking rods 414, drive rods 415, and corresponding slots 413, the stability of the continuous clamping of the workpiece by the multiple clamping plates 52 can be indirectly improved, which helps to further ensure the effect of continuous clamping and fixing of the workpiece by the equipment.

[0028] Meanwhile, the purpose of adding two push blocks and a first telescopic rod 48 between the push rod 411 and the corresponding plate 47, and adding a second telescopic rod 49 between the positioning plate 410 and the corresponding telescopic cylinder 44, is to adaptively adjust the position of the positioning plate 410 on the fixed end of the corresponding telescopic cylinder 44 according to the clamping force required by the workpiece to be welded. At this time, through the cooperation of the servo motor 31 and the limiting mechanism, the corresponding positioning plate 410 can be driven to move left and right through the cooperation of the plate 47 and the corresponding two push blocks and the first telescopic rod 48 (e.g., Figure 9 (as shown in the direction), and during this process, the positioning disk 410 will compress or stretch the corresponding two telescopic rods 49 (and it is set that during this process, the driving force required by the push rod 411, the corresponding positioning disk 410, and the two telescopic rods 49 is small, that is, the telescopic rod 48 drives the positioning disk 410 to move through the corresponding push rod 411, and when the positioning disk 410 moves to compress or stretch the corresponding telescopic rod 49, the push rod 411 cooperates with the corresponding positioning disk 410 and the two telescopic rods 49, and will not compress the corresponding telescopic rod 48 in the opposite direction). When the servo motor 31 cooperates with the drive component to drive the telescopic cylinder 44 to move, the telescopic cylinder 44 will drive the corresponding positioning disk 410 to move together through the corresponding two telescopic rods 49. During this process, although the plate 47 and the two push blocks are in a stationary state, the positioning disk 410 can move by compressing the corresponding telescopic rod 48 through the corresponding push rod 411.

[0029] Reference Figure 4 , Figures 10-15 Multiple adjustment mechanisms each include a sloping groove (shown in the diagram but not labeled, from...). Figure 12As can be seen from the image, the inclined grooves are opened on the corresponding positioning plates 51, and push-pull plates 53 are slidably installed on the inclined grooves. Spring telescopic rods 54 are installed through and fixedly installed on the push-pull plates 53. Two limit grooves are opened at the lower end of the clamping plates 52. Wedges 55 are fixedly installed on the telescopic ends of the spring telescopic rods 54, and the wedges 55 are slidably installed on the corresponding two limit grooves. Transmission components are installed at the lower end of the wedges 55, and pushing components are installed on the positioning plates 51.

[0030] Furthermore, when existing welding fixtures repeatedly clamp and fix different sensor workpieces (such as micro-sensor chips, pin brackets, etc.), "contact friction" occurs at the contact points between the workpiece and the fixture. Over time, this wears down the surface material of the fixture. This is especially true when the fixture clamps and releases sensor workpieces with sharp edges, easily leading to "localized scraping," which exacerbates the wear on the fixture. Simultaneously, the high-temperature welding slag (molten metal slag) generated during the welding process easily splashes onto the fixture surface. Since welding slag has high hardness, it easily adheres to the fixture surface after cooling. When the fixture has weld slag adhering to it... When a fixture clamps and fixes a workpiece, the weld slag adhering to its surface acts as "abrasive particles," exacerbating the wear of the fixture. As the wear of the fixture intensifies, the tightness of the fit between the fixture and the workpiece gradually decreases, meaning the clamping force of the fixture on the workpiece gradually decreases. This can easily lead to displacement of the workpiece during continuous welding, reducing the final welding effect. Furthermore, if the operator judges the wear level of the fixture or replaces the fixture periodically to ensure the stability of the fixture's continuous clamping of the workpiece, there will be instances where replacement is not timely.

[0031] When the device operates via the servo motor 31 and the electric telescopic rod 32, in conjunction with the drive assembly 3 and the clamping assembly 4, it drives the corresponding clamping plate 52 to clamp the workpiece to be welded stably. Then, the electric telescopic rod 32 is restarted. At this time, the operation of the electric telescopic rod 32 will drive the drive gear 1 33, drive gear 2 34, and the push plate 35 to continuously move upwards (e.g., ...). Figure 4 (As shown in the direction), after the push plate 35 contacts the two pushing members 39, the push plate 35 applies an upward pushing force to the two pushing members 39, which can push the two pushing members 39 and the two conical cylinders 310 upward together. During the upward movement of the conical cylinders 310, their sides will apply a rightward squeezing force to the lower cylinder of the corresponding push-pull plate 53 (in combination with...). Figure 11 and Figure 12(As shown in the direction), at this time, according to the "orthogonal decomposition principle of force", the extrusion force can be divided into a component force F1 along the corresponding inclined groove direction and a component force F2 perpendicular to the inclined groove direction. Since the groove wall will generate a reaction force on the "perpendicular component force F2", it will counteract the movement trend of the force direction, while the "component force F1 along the inclined groove" is not blocked. Therefore, when the conical cylinder 310 moves upward and applies an extrusion force to the right side to the corresponding push-pull plate 53, it will drive the push-pull plate 53 to move to the upper right along the corresponding inclined groove.

[0032] Meanwhile, the two limiting grooves at the lower end of the clamping plate 52 ensure that the corresponding wedge 55 is always slidably installed at its lower end. In the initial state, the clamping plate 52 exerts a large pressure on the corresponding wedge 55 by its own weight. Therefore, when the push-pull plate 53 moves to the upper right under the force, causing the fixed end of the corresponding spring telescopic rod 54 to move together, the corresponding wedge 55 cannot be moved together by the telescopic end of the spring telescopic rod 54. That is, the movement of the push-pull plate 53 will stretch the corresponding spring telescopic rod 54 until the conical cylinder 310 cooperates with the corresponding push-pull plate 53. When the elastic tension generated by stretching the corresponding spring telescopic rod 54 is the same as the pressure generated by the clamping plate 52 on the wedge 55 by its own weight, the operation of the electric telescopic rod 32 can be stopped.

[0033] In the initial state, the clamping plate 52 has no wear and its own weight is G. 初始 The horizontal component of the force exerted by the clamping plate 52 on the corresponding wedge 55 is F. 分 =G 初始 ×sinθ, the spring tension F of the spring telescopic rod 54 on the corresponding wedge 55 弹 =kx 初 =G 初始 ×sinθ, when the clamping plate 52 wears down and its weight decreases, i.e., G 新 <G 初始 At this time, the horizontal component F of the clamping plate 52 on the corresponding wedge 55 分新 =G 新 ×sinθ<F 弹 At this time, under the elastic force of the spring telescopic rod 54, the corresponding wedge block 55 will be driven to move to the upper right along the corresponding two limiting grooves (e.g., Figure 12 (as shown in the direction), until the tension of the spring telescopic rod 54 on the corresponding wedge 55 decreases to F. 弹新 =kx 新 =G 新 ×sinθ, the wedge 55 stops moving, and the new pressure exerted by the self-weight of the clamping plate 52 on the corresponding wedge 55 after wear is rebalanced with the new tension of the corresponding spring telescopic rod 54 on the wedge 55 during this stage.

[0034] Reference Figures 3-15Each of the multiple transmission components includes a slide groove 56, and the slide groove 56 is opened on the corresponding positioning plate 51. Each slide groove 56 is slidably mounted with a sliding member 57, and each sliding member 57 is fixedly connected to the corresponding wedge block 55. Each positioning plate 51 is mounted with a rotating shaft that passes through and rotates. A torsion spring is fixedly mounted between the rotating shaft and the corresponding positioning plate 51. Each rotating shaft is fixedly mounted with an adjusting plate 58.

[0035] Each of the multiple moving components includes a drive plate 59, which is slidably mounted through and on the lower end of the corresponding positioning plate 51. Two baffles (shown but not labeled in the figure) are fixedly mounted on each drive plate 59 to cooperate with the corresponding adjusting plate 58. Figure 15 As can be seen from the image, both the drive plate 59 and the corresponding clamping plate 52 are fixedly mounted with rods 510.

[0036] As the wear of the clamping plate 52 gradually intensifies and its clamping force on the workpiece to be welded gradually decreases, according to the above principle, when the pressure applied by the clamping plate 52 to the corresponding wedge 55 is less than the pulling force of the corresponding spring telescopic rod 54 on the wedge 55, the wedge 55 will, under the elastic pulling force of the corresponding spring telescopic rod 54, drive the corresponding sliding member 57 to move obliquely to the upper right along the corresponding slide groove 56 (e.g., Figure 13 and Figure 14 (as shown in the direction), and as the slider 57 moves to the upper right, its lower end roller applies a rightward thrust to the upper end of the corresponding adjusting plate 58, which drives the adjusting plate 58 to rotate clockwise around the corresponding pivot (as shown in the direction). Figure 14 direction shown).

[0037] When the adjusting plate 58 is rotated clockwise under force, the thrust exerted by its lower end on the left baffle of the corresponding drive plate 59 can push the drive plate 59 to move the corresponding rod 510 to the right (e.g., Figure 15 (As shown in the direction), when the rod 510 is moved to the left by the force, it can drive the corresponding clamping plate 52 to move to the right, gradually increasing its clamping force on the workpiece to be welded. In this way, as the clamping plate 52 gradually wears and its clamping force on the workpiece to be welded gradually decreases, the clamping force of the clamping plate 52 on the workpiece to be welded can be increased in a timely and adaptive manner. This helps to improve the coordination of the multiple clamping plates 52 and the continuous and stable clamping effect on the workpiece to be welded, thereby improving the stability of the equipment in continuously clamping the workpiece to be welded.

[0038] Simultaneously, the distance between the upper end of the adjusting plate 58 and the corresponding rotating shaft is defined as the effort arm, and the distance between the lower end of the adjusting plate 58 and the corresponding rotating shaft is defined as the resistance arm. According to the lever principle, effort arm × effort = resistance arm × resistance. Figure 14It can be seen that the power arm of the adjusting plate 58 is much larger than its resistance arm. The adjusting plate 58 is a force-saving lever. Therefore, when the wedge block 55 is subjected to force, it drives the corresponding sliding member 57 to move obliquely to the upper right. When the sliding member 57 drives the adjusting plate 58 to rotate through its lower end roller, only a small force is needed to drive the corresponding driving plate 59, rod 510, and clamping plate 52 to move to the right (e.g., Figure 15 (as shown in the direction) This ensures that when the clamping plate 52 wears and the wedge 55 moves relative to it, the wedge 55 can cooperate with the transmission component and the pushing component to drive the clamping plate 52 to move, adaptively compensating for the clamping force of the clamping plate 52 on the workpiece to be welded, that is, ensuring the stability of the equipment in clamping the workpiece by continuously cooperating with the corresponding multiple clamping plates 52.

[0039] After the workpiece welding is completed, the electric telescopic rod 32 is started first. At this time, the electric telescopic rod 32 runs, driving the drive gear 1 33, drive gear 2 34 and the push plate 35 to move downward. During this process, the corresponding pushing parts 39 and the conical cylinder 310 will move downward under their own gravity (e.g. Figure 4 (As shown in the direction), when the conical cylinder 310 is subjected to downward force and the thrust exerted by its side on the corresponding push-pull plate 53 gradually decreases, the corresponding push-pull plate 53 and the sliding member 57 will, under their own weight and the elastic force of the spring telescopic rod 54, drive the corresponding wedge block 55 to move to the lower left and reset (as shown in the direction). Figure 13 (as shown in the direction), and during this process, the reverse driving force applied to the corresponding rotating shaft by the torsion spring can drive the rotating shaft to rotate and reset the corresponding adjusting plate 58. During the rotation and reset of the adjusting plate 58, the pushing force applied to the right baffle of the drive plate 59 by the lower end of the adjusting plate 58 can drive the drive plate 59 to move and reset the corresponding rod 510 and clamping plate 52.

[0040] When the electric telescopic rod 32 is running, and the drive gear 33 moves down and meshes with the two rotating gears 37, the electric telescopic rod 32 stops running and the servo motor 31 is restarted. At this time, the operation of the servo motor 31 will cooperate with the drive components to drive the corresponding multiple telescopic cylinders 44, positioning plates 51, and clamping plates 52 to move away from each other, thereby releasing the workpiece after welding.

[0041] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0042] In this invention, when the device is needed to clamp and fix the workpiece to be welded, the workpiece is first placed between the corresponding multiple clamping plates 52. Then, through the operation of the electric telescopic rod 32 and the servo motor 31, and the cooperation of the limiting mechanism, the position of the positioning plate 410 is adaptively adjusted according to the required safe clamping force of the workpiece to be welded. After the position of the positioning plate 410 is adjusted, through the operation of the electric telescopic rod 32, the servo motor 31, and the cooperation of the driving components, the corresponding multiple telescopic cylinders 44, positioning plates 51, and clamping plates 52 can be driven to move closer to each other until the corresponding multiple clamping plates 52 cooperate to clamp the workpiece to be welded, achieving the required safe clamping force of the workpiece. At the same time, through the locking component, the position of the clamping plate 52 can be limited after the position of the clamping plate 52 is adjusted, which helps to improve the stability of the corresponding multiple clamping plates 52 continuously cooperating to clamp the workpiece to be welded.

[0043] Meanwhile, through the cooperation of the electric telescopic rod 32 and the adjustment mechanism, the wear degree of the clamping plate 52 can be indirectly detected. At the same time, when the clamping plate 52 continues to wear and its clamping force on the workpiece gradually decreases, the clamping force of the clamping plate 52 on the workpiece can be increased in a timely and adaptive manner through the cooperation of the transmission component and the pushing component. This can effectively ensure the stability and clamping effect of the corresponding multiple clamping plates 52 continuously cooperating to clamp the workpiece, improve the continuous clamping effect of the equipment on the welded workpiece, and help improve the subsequent welding effect of the workpiece.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
