Description

Technical Field

[0001] The invention relates to the technical field of manufacturing process, and in particular to a welding ring correction device and a correction method thereof. Background Art

[0002] In today's booming modern industrial production system, welding rings, as a type of extremely critical connection component, are like an indispensable part of a precision gear set, and are widely and deeply used in many core fields such as electronics, automobiles, and aerospace. From the tiny but precise circuit connections in electronic equipment, to the stable connection of complex parts inside automobile engines, to the assembly of key parts related to flight safety and performance of aerospace aircraft, welding rings play an irreplaceable role.

[0003] A Chinese patent with application number CN201910437906.2 discloses an automatic shaping mechanism for a welding ring, comprising a mounting seat, an advance and retreat cylinder, and a bearing seat; a clamping hook and a clamping cylinder are slidably provided on the bearing seat, the clamping hook has a clamping portion, and a lifting block and a lifting hook are also provided on the bearing seat. The lifting block is slidably provided on the bearing seat, and one end of the lifting hook is rotatably mounted on the bearing seat. During the forward movement of the clamping hook, the lifting hook is driven to cancel the movement restriction of the lifting block. When the clamping hook moves backward into place, the other end of the lifting hook forms a movement restriction on the lifting block, and the lifting block is ejected and cooperates with the clamping portion of the clamping hook to form an elastic lifting member for clamping the welding ring; a rounding member for rounding the welding ring clamped by the lifting block and the clamping portion of the clamping hook is provided on the bearing seat.

[0004] In the actual process of welding ring correction, given the complexity of the welding ring production process, its deformation state is rich and varied. First, in the production process of the welding ring, once the position of the cutter is offset, it will directly cause the openings at both ends of the welding ring to be in a dislocated deformation state, which will make it difficult to accurately dock during subsequent assembly. Second, in the production process of the welding ring, if it is accidentally subjected to external forces such as accidental extrusion or stretching, it is very likely that the size of the welding ring opening will be too large, which will destroy the original sealing performance of the welding ring and have a negative impact on its electrical connection performance, seriously affecting the overall performance and service life of the product.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Embodiment 1 like Figures 1 to 7 As shown, this embodiment discloses a welding ring correction device, including a support component 1, wherein the support component 1 includes a base plate 102, and a correction platform 101 is provided on the upper surface of the base plate 102, and a correction component 3 and a limit component 2 are respectively provided inside the correction platform 101, and the correction component 3 includes a second accommodating space 312 and a second electric push rod 313, wherein the second accommodating space 312 is arranged inside the correction platform 101, and the second electric push rod 313 is arranged at the bottom of the inner wall of the second accommodating space 312, and a second driving rod 307 is provided at the output end of the second electric push rod 313, and an adjusting rod 301 is provided at one end of the second driving rod 307 away from the second electric push rod 313, and a clamping piece 303 is provided at one end of the adjusting rod 301 away from the second driving rod 307 through a connecting rod 310.

[0021] The limiting assembly 2 includes a first accommodating space 211 and a first electric push rod 208. The first accommodating space 211 is arranged inside the correction table 101. The first electric push rod 208 is arranged at the bottom of the inner wall of the first accommodating space 211. A baffle 213 is arranged at the output end of the first electric push rod 208. Two first driving rods 205 are symmetrically arranged on the surface of the baffle 213. The end of the first driving rod 205 away from the baffle 213 passes through the correction table 101. A bearing plate 206 is arranged at the end of the first driving rod 205 close to the surface of the correction table 101. A first welding ring 207 is provided on the top, and the supporting plate 206 is used to support the bottom of the first welding ring 207. A second limiting rod 203 is provided on the inner diameter of the supporting plate 206. A second rubber strip 204 is provided on the outer surface of the second limiting rod 203. The number of the second rubber strips 204 is five, and each of the second rubber strips 204 is distributed in a circular array on the outer surface of the second limiting rod 203. The outer surface of each of the second rubber strips 204 is in contact with the inner diameter of the first welding ring 207. The bottom end of the second limiting rod 203 is fixedly set on the upper surface of the correction table 101.

[0022] When in use, the first electric push rod 208 generates thrust after being energized, pushing the baffle 213 to move, and the baffle 213 drives the first driving rod 205 connected thereto to move, and the first driving rod 205 then drives the supporting plate 206 to rise or fall. When the supporting plate 206 contacts the welding ring, the plane characteristics of the supporting plate 206 are used to fully support the bottom of the welding ring, and the friction and gravity are used to keep the welding ring stable in the vertical direction, which plays a role of preliminary limiting, effectively solving the problem of lack of support and easy displacement of the bottom of the welding ring during the correction process, improving the stability of the welding ring during the correction process, and thus improving the correction accuracy.

[0023] The inner wall of the second limiting rod 203 is slidably provided with a first limiting rod 201, the outer surface of the first limiting rod 201 is provided with a first rubber strip 202, the outer side of the first rubber strip 202 is provided with a second welding ring 212, the number of the first rubber strips 202 is five, each of the first rubber strips 202 is distributed in a circumferential array on the outer surface of the first limiting rod 201, each of the first rubber strips 202 is in contact with the inner diameter of the second welding ring 212, and the bottom end of the first limiting rod 201 is provided with a reset plate 2 10. A compression spring 209 is provided on the side of the reset plate 210 facing the second limit rod 203. The reset plate 210 limits the first limit rod 201 through the compression spring 209. When the first limit rod 201 is in a stressed state, the reset plate 210 moves in the direction of the first limit rod 201, and the compression spring 209 is in a stretched state. When the first limit plate is not in a stressed state, the reset plate 210 slides in the direction of the initial state, and the compression spring 209 is in a contracted state.

[0024] When in use, the first limiting rod 201 can slide on the inner wall of the second limiting rod 203. When welding rings with different inner diameters are placed on the bearing plate 206, the inner diameter of the welding ring will produce different degrees of squeezing or expansion force on the first rubber strip 202 outside the first limiting rod 201. Under the action of this force, the first limiting rod 201 will slide inside the second limiting rod 203, and the compression spring 209 will deform accordingly, storing or releasing elastic potential energy. When the external force disappears, the elastic potential energy of the compression spring 209 will push the reset plate 210 to restore the first limiting rod 201 to a suitable position to adapt to welding rings with different inner diameters, so that the correction device can adapt to welding rings with different inner diameter specifications, expanding the scope of application of the device.

[0025] A U-shaped connector 305 is provided between the second driving rod 307 and the adjusting rod 301. A fixing block 308 is provided on the outer surface of the second driving rod 307. The fixing block 308 is arranged on the upper surface of the hinge platform. The interior of the U-shaped connector 305 is hinged to the adjusting rod 301 through the first hinge shaft 302. An electronic spring is provided at one end of the connecting rod 310 close to the adjusting rod 301. The electronic spring is used to control the longitudinal sliding of the connecting rod 310 on the surface of the adjusting rod 301. A pressure sensor is provided on the surface of the clamping piece. The pressure sensor determines the misalignment degree of the first welding ring 207 and the second welding ring 212 through pressure data. A second hinge shaft 306 is provided at the bottom of the U-shaped connector 305. An angle detector is built into the second hinge shaft 306. The second hinge shaft 306 detects the torsion value between the adjusting rod 301 and the second driving rod 307 through the angle detector. A micro motor is provided at one end of the second hinge shaft 306, and the micro motor is used to control the adjusting rod 301 to rotate along the end of the second driving rod 307.

[0026] When in use, firstly, a second limiting rod 203 is set on the inner diameter of the carrier plate 206, and a plurality of second rubber strips 204 are distributed in a circular array on the outer side. When the welding ring is placed on the carrier plate 206, the second rubber strip 204 is in close contact with the inner diameter of the welding ring. The elasticity and friction of the rubber strip are used to constrain the welding ring, limit its radial shaking, ensure uniform and stable limiting effect, further enhance the limiting ability of the welding ring, improve the correction stability, and provide better conditions for precise correction. Secondly, the angle detector built into the second hinge shaft 306 can monitor the angle and torsion between the adjustment rod 301 and the second driving rod 307 in real time. The change of the rotation value, when the clamping piece 303 contacts the welding ring and applies clamping force to it, the pressure data detected by the pressure sensor is used to determine whether the first welding ring 207 or the second welding ring 212 is in a misplaced deformation state, and by controlling the adjustment rod 301 to rotate along the end of the second driving rod 307, the angle and position of the clamping piece 303 are adjusted to adapt to the deformation of the welding ring to achieve precise correction, thereby realizing real-time detection and precise feedback of the welding ring variables, and being able to automatically adjust the correction force and direction according to the actual deformation of the welding ring, thereby greatly improving the accuracy and quality of the correction.

[0027] A support rod 309 is provided at the bottom of the adjusting rod 301, and a limit block 304 is provided at one end of the support rod 309 away from the adjusting rod 301. A return spring 314 is provided inside the limit block 304, and a sliding block 311 is provided at the other end of the return spring 314. The top of the sliding block 311 is slidably connected to the limit block 304, and the bottom of the sliding block 311 is slidably set inside a slide groove 315. The shape of the slide groove 315 is arc-shaped, and the slide groove 315 is set on the surface of the correction table 101.

[0028] When in use, the support rod 309 is connected to the adjustment rod 301, and part of the force of the adjustment rod 301 is transmitted to the limit block 304. The reset spring 314 and the sliding block 311 inside the limit block 304 cooperate with each other, and the sliding block 311 slides in the arc-shaped slide groove 315. When the adjustment rod 301 is subjected to external force, the sliding block 311 will move accordingly in the arc-shaped slide groove 315, and the reset spring 314 will deform to store elastic potential energy. The elastic potential energy of the reset spring 314 can offset part of the external force, so that the adjustment rod 301 remains relatively stable during the movement. At the same time, the design of the arc-shaped slide groove 315 provides a certain movement trajectory for the sliding block 311, ensuring that the adjustment rod 301 can move in a predetermined direction and range, and realize flexible adjustment, providing stable support and flexible movement space for the adjustment rod 301, effectively preventing the adjustment rod 301 from shaking or being unstable during the movement, and improving the accuracy and stability of correction.

[0029] In summary, when in use, before the welding ring correction work is performed, the welding ring to be corrected needs to be placed on the carrier plate 206. At this time, the limit assembly 2 begins to play a role. The limit assembly 2 includes a first accommodating space 211, a first electric push rod 208, a baffle 213, a first driving rod 205, a carrier plate 206, a second limit rod 203, a second rubber strip 204, a first limit rod 201, a first rubber strip 202, a reset plate 210 and a compression spring 209. Start the first electric push rod 208, which is installed at the bottom of the inner wall of the first accommodating space 211. After power is turned on, a thrust is generated to push the baffle 213 to move. The two first driving rods 205 symmetrically arranged on the surface of the baffle 213 move with the movement of the baffle 213, thereby driving the carrier plate 206 to rise. When the carrier plate 206 rises to a suitable position, it contacts the bottom of the welding ring to provide preliminary support for the welding ring.

[0030] At the same time, the second limiting rod 203 on the inner diameter of the bearing plate 206 begins to function. Five second rubber strips 204 are arranged in a circumferential array on the outer surface of the second limiting rod 203. These second rubber strips 204 are in close contact with the inner diameter of the welding ring. Since the rubber strips have certain elasticity and friction, they can constrain the welding ring in the radial direction, effectively preventing the welding ring from shaking or shifting on the bearing plate 206, and further enhancing the limiting effect on the welding ring.

[0031] In addition, the inner wall of the second limiting rod 203 is slidably provided with the first limiting rod 201, and the outer surface of the first limiting rod 201 is also circumferentially arrayed with five first rubber strips 202. When welding rings with different inner diameters are placed on the bearing plate 206, the inner diameters of the welding rings will produce different degrees of squeezing or expansion forces on the first rubber strip 202. Under the action of this force, the first limiting rod 201 will slide inside the second limiting rod 203, and the compression spring 209 will deform accordingly. When the external force disappears, the elastic potential energy of the compression spring 209 will push the reset plate 210 to restore the first limiting rod 201 to a suitable position to adapt to welding rings with different inner diameters, thereby achieving accurate positioning and stable limiting of welding rings of different specifications.

[0032] During the correction process, the first welding ring 207 is sleeved on the outer surface of the second limiting rod 203. During this process, the inner diameter of the first welding ring 207 contacts the second rubber strip 204. At the same time, since the second rubber strip 204 is elastic, when the first welding ring 207 moves on the surface of the first limiting rod 201, it will continuously form a corresponding extrusion force on the outer surface of the second rubber strip 204, so that after the first welding ring 207 is sleeved on the outer side of the second limiting rod 203, a relatively stable state is formed, and then the first electric push rod 208 is controlled to extend upward, driving the baffle 213 and the first driving rod 20 5 slides upward, so that the bearing plate rises upward, so that the first welding ring 207 moves to a position that is compatible with the adjusting rod 301, and controls the two micro motors to make the two oppositely arranged adjusting rods 301 rotate along the axis of the two second driving rods 307, and at the same time, the limit block 304 under the support rod 309 also slides along the slide groove 315 on the correction table 101, and the sliding block 311 located in the slide groove 315 is in close contact with the inner wall of the slide groove 315 under the tension state of the return spring 314, so that the adjusting rod 301 and the clamping piece 303 are close to the direction of the first welding ring 207.

[0033] It is worth noting that the number of the second electric push rod 313, the second driving rod 307, the adjusting rod 301, the clamping plate 303 and the pressure sensor is two, and each second electric push rod 313, the second driving rod 307, the adjusting rod 301, the clamping plate 303 and the pressure sensor are symmetrically arranged on the left and right sides of the correction platform 101. During the detection process, the two symmetrically arranged pressure sensors are respectively recorded as A and B.

[0034] When the two relatively arranged adjusting rods 301 rotate to drive the clamping pieces 303 to contact the left and right sides of the first welding ring 207, the electronic spring is then controlled to contract, and the connecting rod 310 is controlled to move longitudinally on one side of the adjusting rod 301. In the process, the two clamping pieces 303 clamp the left and right sides of the first welding ring 207 respectively. At this time, the pressure data on the clamping piece 303 is detected and recorded by the pressure sensor on the clamping piece 303.

[0035] When the pressure sensor A and the pressure sensor B detect pressure data at the same time, they are compared with each other. If the difference between the pressure data detected by the pressure sensor A and the pressure sensor B is within the preset value, it means that the left and right sides of the first welding ring 207 are completely clamped by the clamping piece 303 and the adjusting rod 301, and the first welding ring 207 has not been dislocated and deformed. At this time, when the torsion value between the two adjusting rods 301 and the two second driving rods 307 is within the preset value, it means that the first welding ring 207 has neither dislocation and deformation, nor a large deformation problem at the opening due to squeezing or pulling. At this time, no treatment is done, the first welding ring 207 is removed, and the subsequent welding rings are inspected and corrected.

[0036] When the pressure sensor A and the pressure sensor B detect pressure data at the same time, they are compared with each other. If the difference between the pressure data detected by the pressure sensor A and the pressure sensor B is higher than the preset value, it means that there is a misalignment at the opening of the first welding ring 207. If the pressure value detected by the pressure sensor A is lower than that of the pressure sensor B, two angle detectors are used to detect the torsion value between the two adjustment rods 301 and the second driving rod 307. If the torsion value is within the preset value, it means that there is only a misalignment deformation in the first welding ring 207, and the size of the opening is in a normal state. At this time, the second electric push rod 313 in the A area is controlled to extend upward, which will drive the second driving rod 307 to slide upward, so that the adjustment rod 301 is longitudinally deflected under the limiting action of the support rod 309. Rotate, so that the end of the adjustment rod 301 close to the clamping piece 303 will deflect in the direction of the correction table 101, thereby driving the clamping piece 303 to deflect in the direction of the correction table 101, so as to achieve the effect of applying pressure to correct the misaligned and deformed first welding ring 207. At the same time, in this process, the pressure sensor B area does not need to be processed in any way, and it only needs to tightly clamp one side of the first welding ring 207 through the clamping piece 303. At the same time, in the process of correcting the first welding ring 207, the pressure value changes in the correction process are collected by the pressure sensor A until they are equal to the pressure value in the pressure sensor B area and the difference between the pressure sensor A and the pressure sensor B is ensured to be within the preset value. If the pressure data detected by the pressure sensor B is lower than that of the pressure sensor A, the above scheme can be reversed.

[0037] When the pressure sensor A and the pressure sensor B detect pressure data at the same time, they are compared with each other. If the difference between the pressure data detected by the pressure sensor A and the pressure sensor B is within the preset value, it means that both the left and right sides of the first welding ring 207 are completely clamped by the clamping piece 303 and the adjusting rod 301, and the first welding ring 207 does not undergo misalignment and deformation. At this time, when the torsion value between the two adjusting rods 301 and the two second driving rods 307 is higher than the preset value, it means that the first welding ring 207 is squeezed or pulled, resulting in a large deformation at the opening. At this time, only the two adjusting rods 301 need to be controlled. The micro motor makes the adjustment rod 301 rotate along the second driving rod 307, and the two symmetrically arranged adjustment rods 301 rotate toward the left and right sides of the first welding ring 207, and control the clamping pieces 303 to clamp the left and right sides of the first welding ring 207. Then, the micro motor continues to control the two adjustment rods 301 to apply pressure to the left and right sides of the first welding ring 207 toward the axial direction of the second limiting rod 203, so that the two ends of the opening of the first welding ring 207 gather toward the middle. At the same time, two angle detectors are used to detect the torsion value of the adjustment rod 301 in real time. When the torsion value of the adjustment rod 301 and the second driving rod 307 is restored to the initial state, it stops.

[0038] If the pressure sensor detects that the first welding ring 207 is dislocated and deformed, and the angle detector detects that the opening of the first welding ring 207 is too small, the micro motor is first controlled to make the two adjustment rods 301 cooperate with the two clamping pieces 303 to clamp the left and right side surfaces of the first welding ring 207, and then the micro motor is controlled again to make the two adjustment rods 301 rotate away from the first welding ring 207, so that the clamping force generated by the adjustment rods 301 and the clamping pieces 303 on the first welding ring 207 and the pulling force generated by the micro motor on the first welding ring 207 are used to pull the two ends of the opening of the first welding ring 207 outwards, and at the same time, The angle detector detects the opening size of the first welding ring 207 in real time until the opening size of the first welding ring 207 is within the preset value, and then stops using pressure sensor A and pressure sensor B to detect the pressure value. If the pressure value detected by pressure sensor A is smaller than that of pressure sensor B, the second electric push rod 313 is controlled to extend upward, so that the adjustment rod 301 cooperates with the bracket to deflect toward the direction of the correction platform 101, thereby using the adjustment rod 301 and the clamping plate 303 to apply pressure to one side surface of the first welding ring 207 in the pressure sensor A area, so that the pressure difference between pressure sensor A and pressure sensor B is corrected to within the preset value.

[0039] It is worth noting that: if the first welding ring 207 is simultaneously misaligned and deformed and the opening of the first welding ring 207 is too large, the adjustment process is consistent with the above-mentioned scheme, wherein it is only necessary to change the rotation direction of the adjusting rod 301 after clamping the first welding ring 207 through the clamping piece 303 (after the adjusting rod 301 and the clamping piece 303 complete the clamping of the left and right sides of the first welding ring 207, move toward the axial direction of the second limiting rod 203, and at this time, cooperate with the adjusting rod 301 and the clamping piece 303 to achieve squeezing force on the left and right sides of the first welding ring 207, and control the angle detector in real time so that the torsion value between the adjusting rod 301 and the second driving rod 307 is at a preset value).
