Description

Technical Field

[0001] This utility model relates to the technical field of welding devices, and in particular to a welding positioning fixture and welding equipment. Background Technology

[0002] During product manufacturing, to ensure the stability of connections between different components, welding can be used. This involves positioning the different components and then welding them together. (See attached image.) Figure 7 As shown, it is the housing of the vehicle charger. The auxiliary part 102 (bracket) needs to be welded to the main part 101 (extruded plate). In this process, the main part 101 and the auxiliary part 102 need to be positioned separately and then welded at multiple angles and positions to ensure the connection strength after welding.

[0003] In the above process, it is necessary to position the main component and auxiliary component, as well as adjust the angle after positioning. Therefore, the above functions can be achieved by welding positioning fixtures with flipping function, such as a welding flipping platform with application number 202320131691.3, which discloses a welding component that is laterally positioned by a combination of clamping cylinder and slider, and longitudinally positioned by a combination of first clamping cylinder and first pressure plate. It positions a welding component by two sets of driving positioning mechanisms, but cannot effectively achieve synchronous positioning of the auxiliary component on the main component.

[0004] Furthermore, the steps of loading, welding, and unloading materials using a welding positioning fixture during the welding process can lead to low welding efficiency and make it impossible to complete the welding action efficiently and safely. Utility Model Content

[0005] The purpose of this utility model is to provide a welding positioning fixture and welding equipment. The welding positioning fixture can use the pressure plate driven by the first cylinder to position the auxiliary part and the main part in the horizontal and vertical directions by using its downward pressure inclined surface. The structure is simpler and can ensure the stability of the auxiliary part and the main part when the turnover table rotates at a large angle. It is also conducive to cooperating with the welding equipment to complete the welding.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a welding positioning fixture, comprising:

[0007] The support frame has a tilting table on it.

[0008] The positioning assembly includes positioning posts and side pressure members. A plurality of positioning posts are disposed on the flipping table and form positioning cavities between each other for positioning the main component. The side pressure members include a first cylinder disposed on the flipping table and a pressure plate disposed at the output end of the first cylinder. One end of the pressure plate near the positioning cavity forms a downward pressing slope for abutting against an auxiliary component and matching the structure of the auxiliary component.

[0009] As a further optimization, the pressure plate includes a connecting plate and a T-shaped end plate. The connecting plate is disposed on the first cylinder, and the end plate abuts against and locks onto the connecting plate, with the end away from the connecting plate forming the downward pressure slope.

[0010] As a further optimization, a support plate is provided on the side of the positioning cavity on the flipping table. The support plate is provided with a guide groove for the auxiliary part to be embedded and slid therein, which can realize the pre-positioning of the auxiliary part and ensure the accurate position when the auxiliary part abuts against the main part; the end of the pressure plate is driven to extend into the guide groove.

[0011] As a further optimization, the positioning component also includes a pusher, which includes a second cylinder disposed on the tilting table and a push plate disposed at the output end of the second cylinder for abutting against the main component, which can further ensure positioning stability.

[0012] As a further optimization, the tilting table includes a support plate and a rotary motor. The support plate is rotatably mounted on the bracket, and the rotary motor is mounted on the bracket with its output end connected to the support plate.

[0013] As a further optimization, a material sensor is also provided on the tilting table to detect when the material is in place.

[0014] This utility model also provides a welding device, including a frame, and further comprising:

[0015] Welding equipment,

[0016] A rotary worktable is located beside the welding device.

[0017] A pair of the aforementioned welding positioning fixtures are symmetrically arranged on the rotary worktable.

[0018] A partition is disposed on the rotating worktable and located between a pair of welding positioning fixtures.

[0019] As a further optimization, an outer frame is also included, on which an upper baffle is provided. The upper baffle is located above the rotary worktable and forms an opening between it and the rotary worktable. When the rotary worktable rotates, it causes the partition to become flush with the upper baffle and then seals the opening, thereby improving the safety of the welding equipment during operation.

[0020] As a further optimization, the welding device includes a multi-axis manipulator and a welding head disposed at the free end of the multi-axis manipulator.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The welding positioning fixture can use only the first cylinder to drive the pressure plate and use its downward pressing inclined surface to position the auxiliary parts and main parts in the horizontal and vertical directions. The structure is simpler and can ensure the stability of the auxiliary parts and main parts when the turnover table rotates at a large angle. It is also conducive to coordinating with the welding equipment to complete the welding.

[0023] 2. In one specific embodiment, the guide groove on the support plate can pre-position the auxiliary component, ensuring the stability and accuracy of the auxiliary component when it abuts against the main component, which is beneficial to improving the welding quality.

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] like Figures 1 to 3As shown, a welding positioning fixture 100 includes a support 10, a tilting table 20, and a positioning assembly. The tilting table 20 is mounted on the support 10. Preferably, the tilting table 20 includes a support plate 21 and a rotary motor 22. The support plate 21 is rotatably mounted on the support 10. The rotary motor 22 is mounted on the support 10 and its output end is connected to the support plate 21. The positioning assembly is mounted on the support plate 21 and includes positioning posts 31 and side pressure members 32. Preferably, four positioning posts 31 are mounted on the tilting table 20 and form positioning cavities 310 for positioning the main component 101. The side pressure member 32 includes a first cylinder 321 mounted on the tilting table 20 and a pressure plate 322 mounted on the output end of the first cylinder 321. A downward pressing slope 3220 for abutting the auxiliary component 102 is formed on one end of the pressure plate 322 near the positioning cavity 310.

[0033] Combination Figure 7 As shown, in this utility model, based on the positioning of the main component 101, the auxiliary component 102 is simultaneously positioned at the side edge of the main component 101 via its abutment surface 1021. Four positioning posts 31 are arranged in the front, back, left, and right directions of the flipping table 20, forming a non-enclosed positioning cavity 310 between the four positioning posts 31. The main component 101 is placed in the positioning cavity 310 for positioning, and the four side walls of the main component 101 abut against the four positioning posts 31 respectively, which can accurately ensure the position of the main component 101. Multiple (four) auxiliary components 102 are placed at the positions where they need to be welded to the main component 101, that is, with the side pressure component 3. At the opposite position, the pressure plate 322 is driven by the first cylinder 321 to abut against the auxiliary part 102. During the abutment process, the downward pressing slope 3220 of the pressure plate 322 abuts against the top slope 1020 on the auxiliary part 102. The interaction between the two slopes can make the pressure plate 322 press the auxiliary part 102 against the main part 101 in the horizontal direction, and at the same time, it can press the auxiliary part 102 against the main part 101 in the vertical direction. Therefore, only one pressure plate 322 is needed to securely and tightly position the auxiliary part 102 on the main part 101. When welding the auxiliary part 102 and the main part 101, the accuracy and firmness of the welding can be guaranteed. It should be noted that the auxiliary component 102 can be pressed in the horizontal and vertical directions by the pressure plate 322, and the main component 101 can be pressed in the horizontal and vertical directions simultaneously by the force transmission. The vertical pressing effect of the auxiliary component 102 and the main component 101 can be guaranteed without multiple structures. Even when the flipping table 20 is flipped at a large angle to cooperate with the welding action, the main component 101 and the auxiliary component 102 will be stably positioned. The structure can be more optimized and simpler.

[0034] Preferably, the pressure plate 322 includes a connecting plate 3221 and a T-shaped end plate 3222. The connecting plate 3221 is disposed on the first cylinder 321, and the end plate 3222 abuts against and locks against the connecting plate 3221. The end away from the connecting plate 3221 forms a downward pressing slope 3220. Preferably, the end of the end plate 3222 is formed with an extension plate 322a. One side of the T-shaped structure of the end plate 3222 abuts against the extension plate 322a. That is, the end plate 3222 abuts against the connecting plate 3221 in both the horizontal and vertical directions. This can ensure the connection stability between the two and realize the horizontal transmission of force, ensuring that the horizontal force is better applied to the top slope 1020 of the auxiliary component 102 through the downward pressing slope 3220.

[0035] Furthermore, a support plate 323 is provided on the side of the positioning cavity 310 on the flipping table 20. The support plate 323 is provided with a guide groove 3230 for the auxiliary part 102 to be embedded and slide therein. The end of the pressure plate 322 is driven to extend into the guide groove 3230. Based on the above configuration, in the process of positioning the auxiliary part 102 on the main part 101, the auxiliary part 102 can be pre-positioned in the guide groove 3230 on the support plate 323, and then the pressure plate 322 is driven by the first cylinder 321 to extend into the guide groove 3230 to push the auxiliary part 102 to abut against the main part 101 to achieve positioning, which makes the positioning action and positioning process more convenient.

[0036] In one embodiment of the present invention, the positioning component further includes a pusher 33, which includes a second cylinder 331 disposed on the tilting table 20 and a pusher plate 332 disposed on the output end of the second cylinder 331 for abutting against the side wall of the main component 101. The main component 101 can be further stabilized by the action of the pusher plate 332.

[0037] In addition, the welding positioning fixture 100 also includes a material sensor 34 disposed on the support plate 21 to ensure that the main component 101 is located in the positioning cavity 310.

[0038] like Figures 4 to 6As shown, this utility model also provides a welding device, including a frame 40, a rotary worktable 50, a welding device 60, a partition 71, and a welding positioning fixture 100. The welding device 60 preferably includes a multi-axis manipulator 61 and a welding head 62 disposed at the free end of the multi-axis manipulator 61. The rotary worktable 50 is disposed on the frame 40 and located beside the welding device 60. A pair of welding positioning fixtures 100 are symmetrically disposed on the rotary worktable 50. The partition 71 is disposed on the rotary worktable 50 and located between the pair of welding positioning fixtures 100. In this utility model, a pair of welding positioning fixtures 100 are set on the rotary worktable 50. The rotation of the rotary worktable 50 allows the pair of welding positioning fixtures 100 to be positioned on the side of the welding head 62. The welding head 62 is driven by the multi-axis robot 61, and the welding is performed at the connection between the auxiliary part 102 and the main part 101 in coordination with the action of the flipping table 20 in the welding positioning fixture 100. The other welding positioning fixture 100 can be loaded or unloaded by the operator, and the partition 71 separates the two welding positioning fixtures 100 to ensure the safety of the operator.

[0039] Specifically, the rotary worktable 50 is fixedly provided with multiple locking blocks 51. The upper end of the locking block 51 is provided with a locking groove 510. The lower part of the partition 71 is locked in the locking groove 510, which facilitates the disassembly and assembly of the partition. Alternatively, the partition 71 can be locked in the locking groove 510 by bolts that pass horizontally through the locking block 51 and the partition 71.

[0040] The welding equipment also includes an outer frame 70, on which an upper baffle 72 is provided. The upper baffle 72 is located above the rotary worktable 50 and forms an opening 720 between it and the rotary worktable 50. When the rotary worktable 50 rotates, it causes the partition 71 to become flush with the upper baffle 72, thus sealing the opening 720. Through the setting of the outer frame 70 and the cooperation between the upper baffle 72 and the partition 71, the entire welding equipment can be divided into a working area and a material preparation area. The welding device 60 and one welding positioning fixture 100 are located in the working area, and another welding positioning fixture 100 is located in the material preparation area. By rotating the rotary worktable 50, the pair of welding positioning fixtures 100 are positioned in the working area respectively and separated by the partition 71, which can ensure the safety during operation.
