Description

Technical Field

[0001] The present invention relates to the technical field of component forming and welding, and in particular to a forming and welding device for a bimetallic component and a fixing plate of a temperature controller. Background Art

[0002] Thermostats, as the core device for temperature control, are widely used in many fields such as household appliances, industrial equipment, HVAC systems, etc. Their core function is to automatically adjust heating or cooling equipment according to the preset temperature value to maintain the stability of the environment or equipment temperature.

[0003] To adapt to different installation environments, a fixing plate is usually welded to the bimetallic component of the thermostat to improve installation stability and safety. However, while this design has its advantages, it also has certain problems. In particular, during the welding process, a high-density support plate must be placed below the fixing plate to ensure stability. However, due to the poor heat dissipation of the support plate, it can easily cause overheating in the welding area, resulting in deformation of the fixing plate or bimetallic component.

[0051] There are two conveying equipment bodies 1, which are respectively used for the conveying work of the fixing plate and the bimetallic component. Among them, the two conveying equipment bodies 1 for conveying the fixing plate and the bimetallic component are placed at a ninety-degree position, and the mounting frame 31 is fixedly arranged above the corresponding conveying equipment body 1.

[0052] The driving group 32 includes two bevel gears 321 that are meshed and driven and are respectively rotationally connected to the inner wall of the mounting frame 31 through shaft rods. A pulley is fixedly connected to the outer wall of one of the shaft rods, and the pulley is connected to the conveying equipment body 1 through a flat belt drive. The end of the other shaft rod is fixedly provided with a bidirectional screw rod 322 that is rotationally connected to the inner wall of the mounting frame 31, and a linkage block 323 is fitted on the outer wall of the bidirectional screw rod 322.

[0053] The adjusting group 33 includes a trapezoidal plate 331 fixedly connected to the linkage block 323. Sliding grooves are respectively opened on the two inclined sides of the trapezoidal plate 331, and trapezoidal matching platforms 332 are fixedly arranged on the left and right side walls of the trapezoidal plate 331. An installation plate 333 is fixedly arranged inside the mounting frame 31 and below the trapezoidal plate 331. An adjusting member 334 for cooperating with the trapezoidal plate 331 to work and adjusting the position of the fixing plate is arranged on the installation plate 333. Wedge-shaped platforms 335 that are symmetrically arranged on the left and right sides of the adjusting member 334 and are matched with the inclined surfaces of the trapezoidal matching platforms 332 are provided. The side walls of the wedge-shaped platforms 335 are hinged with a strip-shaped plate 336 whose lower end surface is slidably connected to the conveying equipment body 1 through an L-shaped rod.

[0054] The adjusting member 334 includes two adjusting rods 3341 that always slide inside the sliding grooves through rollers and whose lower end surfaces slide through the installation plate 333. Springs on the outer walls of the adjusting rods 3341 are fixedly connected to the installation plate 333, and a rectangular plate 3342 with sliding grooves symmetrically opened in the left and right directions is fixedly arranged on the lower end surface of the adjusting rods 3341. Inverted L-shaped sliders 3343 that are slidably arranged inside the two sliding grooves and are connected to the inner walls of the sliding grooves through springs are provided. The far ends of the two inverted L-shaped sliders 3343 are respectively fixedly connected with pushing rods 3344.

[0055] The flipping group 53 includes a support plate 531 fixedly arranged on the upper end surface of the support platform 51. The support plate 531 is rotatably provided with a rotating boss 532 near the center position of one side wall of the mounting plate 421, and the end surface of the rotating boss 532 has an arc groove corresponding to the support plate 422 and the support plate 423. Electromagnets are installed on the upper and lower side walls of the two arc grooves. The other end of the rotating boss 532 rotates through the support plate 531 and is fixedly connected to the gear 533.

[0056] The positioning group 21 includes a square plate 211 fixed on the welding end of the welding equipment body 2. Two welding heads are provided at the center position of the lower end surface of the square plate 211 through the mounting column. Four conical positioning rods 212 are fixed on the lower end surface of the square plate 211 and on the circumferential outer wall of the mounting column.

[0057] Conveying and position adjustment of fixing plates and bimetallic components:

[0058] During actual use, the corresponding two conveying equipment bodies 1 are started, and the two conveying equipment bodies 1 synchronously convey the fixed plate and the bimetallic component to the supporting part 42. The two conveying equipment bodies 1 both adopt electric transmission, and are respectively provided with multiple groups of conveying rollers, which can effectively reduce the distance between adjacent conveying rollers, thereby improving the stability of the conveying work.

[0059] When the gear 321 is in the forward direction and the gear 322 is in the forward direction, the gear 322 is in the forward direction and the gear 322 is in the forward direction. When the gear 321 is in the forward direction and the gear 322 is in the forward direction, the gear 322 is in the forward direction and the gear 322 is in the forward direction. When the gear 321 is in the forward direction and the gear 322 is in the forward direction, the gear 322 is in the forward direction and the gear 322 is in the forward direction.

[0060] As the trapezoidal plate 331 is driven forward by the linkage block 323, the sliding groove of the horizontal section of the trapezoidal plate 331 gradually moves forward and cooperates with the roller on the front side adjustment rod 3341 to push, thereby causing the front side adjustment rod 3341 to drive the rectangular plate 3342 set thereon to gradually move downward. As the rectangular plate 3342 moves downward, the two inverted L-shaped sliders 3343 sliding in the sliding groove of the rectangular plate 3342 move downward synchronously. In this process, the trapezoidal matching platforms 332 set on the left and right side walls of the trapezoidal plate 331 gradually align with the wedge platform 3342 during the movement of the trapezoidal plate 331. 35 are in contact with each other, and as the trapezoidal plate 331 continues to move forward, the trapezoidal matching platform 332 will push the two wedge-shaped platforms 335 to the left and right sides respectively. At this time, the strip plates 336 under the two wedge-shaped platforms 335 are pushed by their respective hinged L-shaped rods. Under the action of the pushing force of the L-shaped rods, the two strip plates 336 approach each other and push the pushing rods 3344 on the same side respectively. After the two pushing rods 3344 are pushed, the left and right symmetrical inverted L-shaped sliders 3343 approach synchronously. Finally, the two vertical sections of the inverted L-shaped slider 3343 complete the further adjustment of the position of the fixed plate.

[0061] At the same time, when the bimetallic component moves to the top of the corresponding conveying device body 1, the front end bimetallic component is pushed along the waist groove on the support plate 422 by the external pushing mechanism. Since the diameter of the waist groove opened on the support plate 422 is smaller than the diameter of the bimetallic component cover, the bimetallic component will not fall after being pushed into the waist groove. The bimetallic component continues to be pushed. At this time, the two V-shaped clamping blocks 4221 inside the cavity of the limiting section of the support plate 422 are rotated by the thrust and squeeze the tension spring (in the initial state, the V-shaped clamping block 4221 is away from the waist groove opening The mating section on one side is located outside the cavity, while the engaging section of the V-shaped clamp 4221 is initially located inside the cavity of the support plate 422. When the bimetallic component enters along the waist groove, the outer wall of the bimetallic component pushes the mating section, causing the mating section to rotate around the connection point between the mating section and the engaging section. At this time, the mating section moves to the inside of the cavity of the support plate 422, and the engaging section moves to the outer wall of the cavity of the support plate 422 and fits with the outer wall of the bimetallic component). Finally, the electromagnets on the upper and lower walls of the V-shaped clamp are turned on, thereby completing the engaging limit work of the bimetallic component.

[0062] It should be noted that, in the initial state, since the telescopic sleeve between the support plate 423 and the support plate 422 is not compressed, there is a certain gap between the support plate 423 and the support plate 422. When the two conveying equipment bodies 1 convey the fixed plate and the bimetallic component respectively, the gap between the support plate 423 and the support plate 422 can realize the synchronous loading of the fixed plate and the bimetallic component, reducing the time spent on the early loading of the fixed plate and the bimetallic component, and then slightly improving the efficiency of the forming and welding work.

[0063] Forming and welding work of fixing plate and bimetallic components:

[0064] After placing the fixing plate and the bimetallic component on the support plate 422 and the supporting plate 423 respectively, control the welding equipment body 2 to drive the square plate 211 and the conical positioning rod 212 to rotate to directly above the fixing plate, and then control the welding head to move downward. (At the initial position, when the two welding heads in the middle of the square plate 211 are not performing welding work, their lengths are less than the lengths of the four conical positioning rods 212). The two conical positioning rods 212 corresponding to the front and rear directions of the supporting plate 423 preferentially pass through the fixing plate. Since the diameter of the conical positioning rod 212 gradually increases from bottom to top, when the conical positioning rod 212 passes through the fixing plate and the supporting plate 423, the secondary alignment of the fixing plate is realized through the outer walls with diameter changes of the two conical positioning rods 212. (During the downward movement of the conical positioning rod 212, the end with a smaller diameter will preferentially enter the holes on both sides of the fixing plate. As the conical positioning rod 212 gradually moves downward, the inner expansion of the holes of the fixing plate is realized through its outer wall with a larger diameter). The conical positioning rods can not only ensure the smooth progress of the positioning work, but also the synchronous movement of the two conical positioning rods 212 can ensure that the central hole of the fixing plate and the mounting column are concentric and coaxial, thereby improving the later welding quality and avoiding the phenomenon of false welding and missed welding caused by the non-concentricity between the fixing plate and the welding head.

[0065] As the two conical positioning rods 212 continue to move downward, their lower end surfaces contact the return plate 4243 and push the return plate 4243 downward. At this time, the return plate 4243 and the supporting plate 423 move away from each other, and the four hinge rods provided on the return plate 4243 respectively pull the corresponding adjusting plates 4242 downward. After being pulled, the adjusting plates 4242 change from the initial horizontal state to an inclined state. As the return plate 4243 continues to move downward, to compensate for the distance between the return plate 4243 and the adjusting plate 4242, the arc-shaped top plate 4241 slides at this time and moves into the sliding groove. (In the initial state, the four arc-shaped top plates 4241 all penetrate the supporting plate 423 and are located on the inner wall of the middle through hole. When the four arc-shaped top plates 4241 move away synchronously, the lower bimetallic component will gradually pass through the through hole in the middle of the supporting plate 423 due to the lack of obstruction, and the outer wall of the bimetallic component will be in contact with the inner wall of the central hole of the fixing plate).

[0066] At the same time, the other two relatively positioned conical positioning rods 212 respectively push the corresponding two T-shaped pressing blocks 42323 during the downward movement. When the two T-shaped pressing blocks 42323 move downward, they stretch the springs and move to the bottom end of the C-shaped adjusting frame 42321, and then turn on the power supply of the electromagnet, so that the two T-shaped pressing blocks 42323 are electromagnetically fixed to the C-shaped adjusting frame 42321 respectively. The upper surface of the fixing plate is limited by the two T-shaped pressing blocks 42323, which improves the stability of the fixing plate on the supporting plate 423 and avoids the vibration of the fixing plate due to external forces during the later welding process.

[0067] Finally, control the two welding heads to extend synchronously to complete the welding work at the connection between the fixing plate and the bimetal component.

[0068] It should be noted that a U-shaped adjusting frame 42321 is fixedly arranged on the upper end surface of the supporting plate 423. Two guide plates with opposite inclination directions are fixedly arranged at the opening of the U-shaped adjusting frame 42321. After the fixing plate completes the position adjustment and enters the supporting plate 423, the position adjustment of the fixing plate is further completed through the two inclined guide plates. The non-opening end of the U-shaped adjusting frame 42321 will block the fixing plate, so as to ensure that the fixing plate cannot continue to move forward after moving to the specified position, thereby making the position of the fixing plate consistent during each welding.

[0069] There is a certain height difference between the arc-shaped top plate 4241 and the adjusting plate 4242. When the arc-shaped top plate 4241 is pulled into the supporting plate 423 and the connection between the fixing plate and the bimetal component is welded, the excess heat will be discharged through a plurality of heat dissipation holes 4231 opened on the supporting plate 423, avoiding the deformation of the fixing plate or the bimetal component caused by local overheating of the welding point. At the same time, the welding flame will be intercepted by the arc-shaped top plate 4241 after entering the heat dissipation holes 4231, preventing the flame from directly falling with gravity and adhering to the outer surface of the bimetal component.

[0070] Welding work on the reverse side of the fixing plate and the bimetal component:

[0071] After the welding head completes the single-sided welding work of the fixing plate and the bimetal component, first control the welding equipment body 2 to move the square plate 211 and the conical positioning rod 212 away from the fixing plate and the bimetal component. After the conical positioning rod 212 is separated from the supporting plate 423, the supporting plate 423 lacking downward pressure is reset upward under the elastic force of the telescopic sleeve. Since the fixing plate and the bimetal component have completed the single-sided welding and are connected into a whole, the bimetal component will not fall downward into the waist slot of the supporting plate 422 after the conical positioning rod 212 is separated.

[0072] Then, the external stepper motor drives the support tray 41 to rotate ninety degrees, and the fixed plate and bimetallic component with single-sided welding are moved to the inside of the rotating boss 532 under the drive of the support plate 423 and the support plate 422. Then, the electromagnets on the upper and lower side walls of the rotating boss 532 are activated, so that the rotating boss 532 is electromagnetically fixed to the support plate 422 and the support plate 423. Then, the external driving device is controlled to engage the gear 533 to rotate. During the rotation process, the gear 533 synchronously drives the rotating boss 532, the support plate 423 and the support plate 422 to rotate. When the mounting plate 421 is rotating, the scroll spring inside it is compressed. Since the T-shaped clamping block 42323 is always in contact with the upper surface of the fixed plate, the fixed plate and the bimetallic component will not slide due to gravity during the rotation process. After the fixed plate and the bimetallic component rotate one hundred and eighty degrees, the power supply of the electromagnets on the two T-shaped clamping blocks 42323 is disconnected. At this time, the fixed plate and the bimetallic component will fall to the support platform 51 below due to lack of support. Then, while disconnecting the power supply of the electromagnet on the rotating boss 532, the stepper motor is started to drive the mounting disk 421 to rotate. When the mounting disk 421 is separated from the rotating boss 532, the scroll spring inside it is reset and drives the mounting disk 421 to rotate.

[0073] When the mounting plate 421 drives the support plate 422 and the support plate 423 to rotate and move, the obstruction between the fixed plate and the upper end surface of the bimetallic component disappears. At this time, the welding equipment body 2 is controlled to drive the welding head to rotate to the top of the fixed plate, and the welding head completes the welding work of the connection point between the fixed plate and the back side of the bimetallic component. Finally, the external lifting equipment lifts the welded fixed plate assembly upward and collects it into the external storage box.

[0074] It is worth emphasizing that the forming welding equipment has the following main advantages:

[0075] Advantage 1: There is a certain height difference between the curved top plate 4241 and the adjustment plate 4242. When the curved top plate 4241 is pulled into the supporting plate 423 and the connection between the fixed plate and the bimetallic component is welded, excess heat will be discharged through the several heat dissipation holes 4231 opened on the supporting plate 423, thereby preventing local overheating of the welding point from causing deformation of the fixed plate or the bimetallic component. At the same time, the welding flames will be intercepted by the curved top plate 4241 after entering the heat dissipation holes 4231, thereby preventing the flames from directly falling due to gravity and adhering to the outer surface of the bimetallic component.

[0076] Advantage 2: The supporting plate 423 and the support plate 422 are connected by a telescopic sleeve. Through the gap between the supporting plate 423 and the support plate 422, the fixed plate and the bimetallic component can be loaded synchronously, which reduces the initial loading time and thus slightly improves the forming and welding work efficiency.

[0077] Advantage three: When the conical positioning rod 212 moves downward, the end with a smaller diameter will preferentially enter the holes on both sides of the fixed plate. As the conical positioning rod 212 gradually moves downward, the outer wall with a larger diameter will expand the hole of the fixed plate inward. The conical positioning rod can not only ensure the smooth positioning work, but also the synchronous movement of the two conical positioning rods 212 can ensure that the hole in the middle of the fixed plate is concentric and coaxial with the mounting column, thereby improving the quality of subsequent welding and avoiding the phenomenon of false welding and leaking welding due to the non-concentricity of the fixed plate and the welding head.

[0078] Advantage 4: As the trapezoidal plate 331 continues to move forward, the trapezoidal matching platform 332 will push the two wedge-shaped platforms 335 to the left and right sides respectively. At this time, the strip plates 336 under the two wedge-shaped platforms 335 are pushed by their respective hinged L-shaped rods. Under the action of the thrust of the L-shaped rods, the two strip plates 336 approach each other and push the pushing rods 3344 on the same side respectively. After the two pushing rods 3344 are pushed, the inverted L-shaped sliders 3343 symmetrically move closer together. Finally, the inverted L-shaped sliders 3343 are pushed closer together. The two vertical sections complete the adjustment of the fixed plate position, ensuring the stability of the fixed plate position during transportation. At the same time, the outer wall of the bimetallic component pushes the mating section, causing the mating section to rotate around the connection point between the mating section and the engaging section, and the engaging section moves to the outer wall of the support plate 422 cavity and fits with the outer wall of the bimetallic component to complete the engaging and limiting work of the bimetallic component. The limiting work of the engaging section ensures the relative position of the bimetallic component and the fixed plate, laying the foundation for the subsequent coordinated movement of the fixed plate and the bimetallic component.
