Description

Technical Field

[0001] This application relates to the technical field of kitchenware parts processing, and in particular to a welding fixture. Background Technology

[0002] like Figure 1 As shown, the ring is a part of the kitchen utensil. The ring is made by bending a long strip into a circle, with the two ends of the strip abutting each other, and then welding the joints at the two ends of the strip together using a welding torch.

[0003] The industry standard method involves manual operation. Specifically, the operator holds both ends of a long, bent strip, applying force with both hands simultaneously to bring the ends together. The operator then carefully moves the joint to the output end of the welding torch and welds the ends together. Throughout this process, the operator must maintain complete focus on controlling the force and position of their hands to ensure accurate contact and successful welding.

[0004] However, this existing manual processing method has obvious drawbacks. During the welding process, the operator's hands may shake due to manual operation. This shaking can cause the contact positions at both ends of the long strip to shift, thus affecting the welding effect of the ring. Utility Model Content

[0005] The purpose of this application is to provide a welding fixture to improve the stability of a ring during welding.

[0006] The welding fixture provided in this application adopts the following technical solution: it includes a welding table, a fixed clamp connected to the welding table, a movable clamp slidably connected to the welding table, a driving assembly connected to the welding table, the driving assembly being used to drive the movable clamp to slide towards or away from the fixed clamp, both the fixed clamp and the movable clamp being provided with mounting grooves, and a clamping assembly connected to the welding table, the clamping assembly being used to fix both ends of the long strip plate to the fixed clamp and the movable clamp respectively.

[0007] By adopting the above technical solution, a long strip is installed on the welding table, with both ends of the strip located in two mounting slots. A clamping assembly clamps both ends of the strip, fixing them to a fixed clamp and a movable clamp, respectively. A driving assembly drives the movable clamp to slide closer to the fixed clamp, meaning one end of the strip slides closer to the other end until the two ends meet. The driving assembly then stops, and the welding torch welds the connection between the two ends of the strip. This welding fixture avoids shaking caused by manual operation, prevents the ends of the strip from shifting during welding, and improves the stability of the ring during welding, thus enhancing the welding effect.

[0008] Optionally, the driving assembly includes a movable plate slidably connected to the welding table and a first driving member for driving the movable plate to slide toward or away from the fixed clamp. The first driving member is connected to the welding table, the movable clamp is connected to the movable plate, and the clamping assembly includes two clamping structures, one of which is connected to the movable plate and corresponds to the movable clamp, and the other of which is connected to the welding table and corresponds to the fixed clamp.

[0009] By adopting the above technical solution, when the two ends of the long strip are respectively located in the two mounting slots, the two clamping structures clamp the two ends of the long strip respectively. The first driving member drives the movable plate to slide towards the fixed clamp. One of the clamping structures and the movable clamp move with the movement of the movable plate, so that the two ends of the long strip abut against each other, avoiding manual force on the two ends of the long strip, thereby preventing the abutment position of the two ends of the long strip from shifting during welding.

[0010] Optionally, the inner wall of the mounting groove is formed with a clamping surface, and the clamping structure includes a clamping plate and a second driving member. The mounting groove is located between the clamping surface and the clamping plate, and the second driving member is used to drive the clamping plate to slide towards or away from the mounting groove.

[0011] By adopting the above technical solution, when the two ends of the long strip are respectively located in the two mounting slots, the second driving member drives the clamping plate to slide towards the clamping surface, the clamping plate abuts against the long strip, and the long strip is clamped by the clamping plate and the clamping surface, thereby fixing the two ends of the long strip on the fixed clamp and the movable clamp respectively.

[0012] Optionally, the welding table is slidably connected to a positioning plate, the positioning plate being located between the fixed clamp and the movable clamp, and the welding table is connected to a third driving member, the third driving member being used to drive the positioning plate to rise and fall.

[0013] By adopting the above technical solution, when installing the long strip, the positioning plate is located between the fixed clamp and the movable clamp. Both ends of the long strip abut against the opposite sides of the positioning plate, ensuring the long strip is precisely placed in the corresponding position, bringing its ends as close as possible and shortening the movement distance at one end. After the long strip is positioned, two clamping structures fix both ends of the long strip, and a third drive lowers the positioning plate, moving it below the movable plate to prevent it from obstructing the movement of the movable plate and the movable clamp.

[0014] Optionally, the welding table is connected to a support plate, the support plate is slidably connected to a carrier plate, the support plate is connected to a fourth driving member, the fourth driving member is used to drive the carrier plate to slide towards or away from the fixed clamp, the side of the carrier plate near the fixed clamp is fixedly connected to a first pressing plate and slidably connected to a second pressing plate, the first pressing plate corresponds to the fixed clamp, and the second pressing plate corresponds to the movable clamp.

[0015] By adopting the above technical solution, when both ends of the long strip are fixed by the two clamping structures respectively, the fourth driving member drives the carrier plate to slide towards the fixed clamp. The first pressing plate and the second pressing plate move with the carrier plate until the first pressing plate abuts against the long strip on the fixed clamp, and the second pressing plate abuts against the long strip on the movable clamp, further improving the effect of pressing the two ends of the long strip, that is, improving the stability of the two ends of the long strip. When the movable clamp slides, because the second pressing plate abuts against the long strip, the second pressing plate moves with the movement of the movable clamp.

[0016] Optionally, both the first pressing plate and the second pressing plate have a buffer pad attached to the side near the welding table.

[0017] By adopting the above technical solution, a buffer pad is connected to the side of the first pressing plate and the second pressing plate near the welding table, which can prevent the first pressing plate and the second pressing plate from directly contacting the long strip plate, and play a buffering role when pressing the long strip plate, reducing damage to the long strip plate.

[0018] Optionally, the side of the buffer pad closest to the welding station has an outer arc shape.

[0019] By adopting the above technical solution, the side of the buffer pad near the welding table is shaped like an outer arc, which makes the contact between the buffer pad and the long strip plate more intimate, increases the contact area between the buffer pad and the long strip plate, and improves the effect of the buffer pad pressing the long strip plate.

[0020] Optionally, the carrier plate is connected to a mounting plate, the second pressing plate is connected to a second connecting post, the second connecting post is connected to a connecting plate, the mounting plate is provided with a sliding groove and a clearance groove communicating with the sliding groove, the sliding groove is used to slide and engage with the connecting plate, the clearance groove is used to slide and engage with the second connecting post, the connecting plate is connected to an elastic element, and the end of the elastic element away from the connecting plate is connected to the mounting plate.

[0021] By adopting the above technical solution, when the second pressing plate moves synchronously with the movable clamp, the sliding engagement between the connecting plate and the slide groove, as well as the sliding engagement between the second connecting column and the clearance groove, guides and limits the sliding of the second pressing plate, thereby improving the stability of the sliding of the second pressing plate. The elastic element undergoes elastic deformation under tension and maintains a tendency to elastically return to its original position. When the buffer pad on the second pressing plate separates from the long strip, the elastic element elastically returns to its original position, forcing the connecting plate, the second connecting column, and the second pressing plate to return to their original positions, facilitating the reuse of the second pressing plate.

[0022] Optionally, the carrier plate is rotatably connected with a plurality of ball bearings, all of which are distributed along the moving direction of the connecting plate, and the connecting plate abuts against the ball bearings.

[0023] By adopting the above technical solution, the contact between the connecting plate and the ball can reduce the friction when the connecting plate moves, making the movement of the connecting plate on the carrier plate smoother.

[0024] Optionally, the carrier plate is provided with a plurality of rotating grooves, each corresponding to a ball bearing. The ball bearing rotates within the rotating groove, and the rotating groove communicates with the sliding groove. The carrier plate is connected to a limiting plate, which is connected to a locking member. The limiting plate is connected to the carrier plate through the locking member. The limiting plate is provided with a plurality of clearance grooves corresponding to each ball bearing. The clearance grooves are used to rotate and engage with the ball bearings.

[0025] By adopting the above technical solution, the rotational engagement between the ball bearing and the rotating groove improves the stability of the ball bearing's rotation. The limiting plate prevents the ball bearing from detaching from the rotating groove during rotation.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Welding fixtures can avoid shaking caused by manual operation, prevent the two ends of the long strip from shifting during welding, improve the stability of the ring during welding, and thus improve the welding effect of the ring.

[0027] 2. When both ends of the long strip are fixed by the two clamping structures, the fourth driving component drives the carrier plate to slide towards the fixed clamp. The first and second pressing plates move with the carrier plate until the first pressing plate abuts against the long strip on the fixed clamp, and the second pressing plate abuts against the long strip on the movable clamp, further improving the effect of pressing the ends of the long strip, i.e., improving the stability of the ends of the long strip. When the movable clamp slides, because the second pressing plate abuts against the long strip, the second pressing plate moves with the movement of the movable clamp. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 2 - Appendix Figure 9 This application will be described in further detail.

[0038] This application discloses a welding fixture.

[0039] Example 1 Combination Figure 2 , Figure 3 and Figure 4 As shown, the assembly includes a welding table 1 and a clamping assembly 2. The welding table 1 includes a base plate 11, a top plate 12, and three support rods 13. The support rods 13 are located between the top plate 12 and the base plate 11, and their two ends are fixedly connected to the base plate 11 and the top plate 12, respectively. A fixed clamping seat 3 is fixedly connected to the side of the top plate 12 away from the base plate 11. A movable clamping seat 4 is slidably connected to the base plate 11. A driving assembly 5 is connected to the base. The driving assembly 5 includes a movable plate 51 slidably connected to the base plate 11 and a first driving member 52 fixedly connected to the base plate 11. The first driving member 52 is a cylinder and is externally connected to a controller (not shown in the figure). The signal output terminal of the controller is connected to the signal input terminal of the first driving member 52. The movable plate 51 is fixedly connected to the output terminal of the first driving member 52. The first driving member 52 drives the movable plate 51 to slide towards or away from the fixed clamping seat 3. The movable clamping seat 4 is fixedly connected to the upper surface of the movable plate 51 and corresponds to the fixed clamping seat 3.

[0040] Combination Figure 2 , Figure 3 and Figure 4 As shown, both the fixed clamp 3 and the movable clamp 4 have mounting grooves 31 on their upper surfaces. The mounting grooves 31 penetrate the opposite sides of the fixed clamp 3 and the movable clamp 4. The inner wall of the mounting groove 31 near the bottom plate 11 is arc-shaped, and one side wall of the mounting groove 31 is a clamping surface 32. The clamping assembly 2 includes two clamping structures 21, which are respectively connected to the movable plate 51 and the top plate 12. One clamping structure 21 corresponds to the movable clamp 4, and the other clamping structure 21 corresponds to the fixed clamp 3. The two clamping structures 21 have the same structure, but are installed in different positions. The clamping structure 21 installed on the movable plate 51 is described as an example. The clamping structure 21 includes a clamping plate 211 that is slidably connected to the movable plate 51 and a second driving member 212 that is fixedly connected to the movable plate 51. The mounting groove 31 is located between the clamping plate 211 and the clamping surface 32. The second driving member 212 is a cylinder. The signal output terminal of the controller is connected to the signal input terminal of the second driving member 212. The side of the clamping plate 211 near the second driving member 212 is fixedly connected to the output terminal of the second driving member 212. The second driving member 212 drives the clamping plate 211 to slide towards or away from the clamping surface 32.

[0041] Combination Figure 2 , Figure 3 and Figure 4 As shown, a positioning plate 14 is slidably connected to the base plate 11. The positioning plate 14 is located between the fixed clamp 3 and the movable clamp 4. A third driving member 15 is fixedly connected to the base plate 11. The third driving member 15 is a cylinder. The signal output terminal of the controller is connected to the signal input terminal of the third driving member 15. The side of the positioning plate 14 closest to the third driving member 15 is fixed to the output terminal of the third driving member 15. The third driving member 15 drives the positioning plate 14 to rise and fall.

[0042] The implementation principle of a welding fixture in this application embodiment is as follows: When installing the long strip, the positioning plate 14 is located between the fixed clamp 3 and the movable clamp 4. Both ends of the long strip abut against the opposite sides of the positioning plate 14, ensuring the long strip is precisely positioned. Both ends of the long strip are located within two mounting slots 31. The second driving member 212 drives the clamping plate 211 to slide towards the clamping surface 32, abutting against the long strip. The long strip is clamped by the clamping plate 211 and the clamping surface 32, thus fixing both ends of the long strip to the fixed clamp 3 and the movable clamp 4 respectively. The third driving member drives the positioning plate 14 to descend, moving it below the movable plate 51 to prevent it from obstructing the movement of the movable plate 51 and the movable clamp 4. The first driving component 52 drives the movable plate 51 to slide towards the fixed clamp 3. One of the clamping structures 21 and the movable clamp 4 move with the movable plate 51, causing the two ends of the long strip to abut against each other. This avoids manual force being applied to the ends of the long strip, thus preventing the abutment position of the two ends of the long strip from shifting during welding. The welding torch then welds the joint between the two ends of the long strip. The welding fixture avoids shaking caused by manual operation, prevents the abutment position of the two ends of the long strip from shifting during welding, and improves the stability of the ring during welding, thereby improving the welding effect of the ring.

The connecting plate 8 abuts against the balls 9.

[0045] like Figure 7 As shown, a second pressing plate 83 is fixedly connected to the end of the second connecting column 81 away from the connecting plate 8. The second pressing plate 83 is located above the movable clamp 4 and corresponds to the movable clamp 4.
