Description

Technical Field

[0001] The utility model relates to the field of automobile frame processing, and particularly relates to a frame welding tooling capable of multi-axis adjustment. Background Art

[0002] The frame is the base of the whole automobile, used to support and connect various parts of the automobile, and bear various loads from inside and outside the vehicle. Since the structures such as the engine, transmission system, suspension, steering, cab, cargo box and related operating mechanisms of the automobile are all fixed in position through the frame, the width, length and abdominal height of the frames of different automobiles need to be designed according to actual needs, resulting in differences in the width, length and abdominal height of the frames of different automobiles.

[0003] During the assembly process of the automobile, the frame needs to be welded. Traditional welding tooling usually can only clamp the frame, and by moving the welding station, the parts to be welded are aligned with the welding structure to complete the welding. However, for the frames of larger-sized automobiles such as buses, the frames are larger, and it is more difficult to move the welding station; and when welding frames of different sizes, due to the different sizes of the frames, the positions of the parts to be welded on different frames are different. At this time, only the positions of each welding station can be adjusted. However, there are many parts to be welded on the frame, resulting in many welding stations. On the one hand, it takes a long time to adjust; on the other hand, in order to improve the welding efficiency, parts such as lugs installed on the frame also need to be moved to the adjusted position, which leads to the need to synchronously move the position of the conveying device that transports the parts to the welding station or requires manual secondary movement of the parts to ensure that the parts are moved to the adjusted welding station. Therefore, adjusting the welding station will undoubtedly cause other impacts.

[0004] Although later, as shown in the frame welding tooling disclosed in the application number CN202110343620.5, a flipping device is provided, including a machine base and a rotating assembly, and the rotating assembly is rotatably arranged relative to the machine base; a frame, connected to the rotating assembly to drive the frame to rotate around a preset axis through the rotating assembly; a supporting device, arranged on the frame, and the supporting device includes a driving structure and a supporting structure, and the supporting structure is used to support the frame to be welded; wherein, the driving structure is drivingly connected to the supporting structure to drive the supporting structure to reciprocate in a preset direction, so as to adjust the relative distance between the frame to be welded and the frame; the preset direction is the direction from the frame to the frame to be welded.

[0005] Although the above invention solves the problem that the height of the existing frame on the flipping welding mechanism is not adjustable, increasing the welding difficulty, the adjustment direction is single. When welding frames of different sizes, it is difficult to adjust from the width and length directions of the frame. Therefore, in order to adapt to frames of different sizes, a large-distance adjustment of the welding station is still required. Content of the Utility Model

[0006] The utility model aims to provide a frame welding tooling capable of multi-axis adjustment to solve the problem that the distance to be adjusted at the welding station is too large.

[0007] To achieve the above object, the utility model adopts the following technical scheme: a frame welding tooling capable of multi-axis adjustment, including a slide rail, a base and two positioning units. The base is perpendicular to the slide rail and is slidably matched with the slide rail. The two positioning units are both arranged on the base and are symmetrically arranged along the base. The positioning unit includes a horizontal adjustment component and a vertical adjustment component. The vertical adjustment component includes a vertical pushing member and a mounting bracket. The vertical pushing member is arranged on the base, and the vertical pushing member is connected to the mounting bracket and is used to push the mounting bracket to slide vertically. The horizontal adjustment component includes a horizontal pushing member, a connecting member and a positioning member. The horizontal pushing member is arranged on the mounting bracket, the horizontal pushing member is connected to the connecting member and is used to push the connecting member to slide towards the side close to the other positioning unit, and the positioning member is arranged on the connecting member.

[0008] The beneficial effect of this scheme is:

[0009] The positioning member in this scheme can position the frame. When the base slides along the slide rail, the position of the frame can be adjusted along the length direction of the frame. The position of the frame can be adjusted along the width direction of the frame through the horizontal pushing member, and the position of the frame can be adjusted along the height direction through the vertical pushing member. Therefore, the frame can be moved along the length, width and height directions of the frame without moving the welding station, so that the position to be welded of the frame is aligned with the welding station, the adjustment is fast, and it is no longer necessary to fully rely on adjusting the welding station, effectively reducing the welding difficulty.

[0010] Further, the connecting member includes a fixed block and a transition block. The horizontal pushing member is connected to the fixed block and is used to push the fixed block to slide. The transition block is detachably connected to the fixed block, and the positioning member is connected to the transition block.

[0011] The beneficial effect of this scheme is: a transition block is arranged between the positioning member and the fixed block. During installation, the relative position of the positioning member and the fixed block can be adjusted by adjusting the connection position between the transition block and the fixed block and the connection position between the transition block and the positioning member. The position of the positioning member can be finely adjusted without adjusting the base and the horizontal pushing member.

[0012] Further, there are two transition blocks, and both transition blocks include a first connecting portion and a second connecting portion distributed in an L shape. The first connecting portion and the second connecting portion of the same transition block are fixed; the first connecting portion of one transition block is connected to the fixed block, and the first connecting portion of the other transition block is connected to the positioning member; a fixing hole is arranged on one of the second connecting portions, and a plurality of mounting holes capable of being aligned with the fixing hole are arranged on the other second connecting portion.

[0013] The beneficial effects of this solution are as follows: In this solution, by aligning the fixing holes with different mounting holes, bolts or positioning pins are passed through the aligned fixing holes and mounting holes, and the two transition blocks can be quickly connected, thus more conveniently adjusting the relative position between the positioning member and the fixing block. Secondly, the two second connecting portions in this solution are in contact with each other, with a larger contact area and more stable installation.

[0014] Furthermore, the mounting bracket includes a mounting plate and two vertical plates. The mounting plate is connected to the vertical pushing member. The two vertical plates are vertically mounted on the mounting plate. A guiding rod is provided between the two vertical rods. The fixing block is located between the two vertical plates. The guiding rod horizontally penetrates the fixing block, and the fixing block is slidably engaged with the guiding rod.

[0015] The beneficial effects of this solution are as follows: The guiding rod in this solution can guide the sliding of the fixing block, preventing the fixing block from skewing when sliding. And the two vertical plates are respectively located on both sides of the fixing block, respectively supporting the two ends of the guiding rod, and having a better supporting effect on the guiding rod and the fixing block.

[0016] Furthermore, a vertical guiding rod is fixed on the mounting bracket. The vertical guiding rod vertically penetrates the base and is slidably engaged with the base.

[0017] The beneficial effects of this solution are as follows: The vertical guiding rod can guide the sliding of the mounting bracket, preventing the mounting bracket from skewing.

[0018] Furthermore, a positioning seat parallel to the sliding rail is provided below the base. A plurality of jacks are axially provided on the positioning seat. A positioning hole capable of aligning with any one of the jacks is provided on the base. A plug rod is slidably provided in the positioning hole.

[0019] The beneficial effects of this solution are as follows: When the plug rod is aligned with the positioning hole, the plug rod slides downward and can be inserted into the aligned positioning hole. At this time, the base can be positioned, so that the vehicle frame will not move along the direction of the sliding rail during the welding process.

[0020] Furthermore, a clamping ring is fixed on the plug rod, and after the lower end of the plug rod is located in the jack, the clamping ring is clamped with the positioning hole.

[0021] The beneficial effects of this solution are as follows: After the clamping ring is clamped with the positioning hole, the plug rod is not easy to shake, thereby further improving the positioning effect on the base. Description of the Drawings

[0029] Positioning seats 3 are provided below the left end and the right end of the horizontal plate 2. The positioning seats 3 are parallel to the slide rail 1 and are installed on the vehicle frame by bolts. Taking the positioning seat 3 on the right side as an example, a plurality of jacks 301 are axially provided on the positioning seat 3. A positioning hole capable of aligning with any one of the jacks 301 is provided on the horizontal plate 2, and a plug rod 4 is vertically slidably arranged in the positioning hole. The diameter of the plug rod 4 is smaller than the diameter of the positioning hole, and an annular clamping ring 401 is sleeved on the plug rod 4. After the clamping ring 401 in this embodiment slides downward into the positioning hole and the jack 301, the inner walls of the positioning hole and the jack 301 are both abutted against the outer wall of the clamping ring 401, so that the clamping ring 401 is clamped with the jack 301 and the positioning hole.

[0030] Two positioning units are symmetrically arranged at the left and right ends of the base. In this embodiment, the two positioning units are respectively located on two U-shaped frames 5. Taking the positioning unit on the right side as an example, the positioning unit includes a horizontal adjustment component and a vertical adjustment component. The vertical adjustment component includes a vertical pushing member 6 and a mounting bracket 7. The mounting bracket 7 in this embodiment includes a mounting plate 702 and two vertical plates 701. The mounting plate 702 is horizontal, and the two vertical plates 701 are vertically welded to the top of the mounting plate 702. The vertical pushing member 6 is a cylinder. The vertical pushing member 6 is installed on the U-shaped frame 5 by bolts, and the push rod of the vertical pushing member 6 faces upward and is connected to the bottom of the mounting plate 702 through a flange for pushing the mounting plate 702 to slide vertically. Vertical guide rods 703 are vertically arranged at the four corner positions of the mounting plate 702. In this embodiment, the vertical guide rods 703 are connected to the vertical plates 701 by bolts, and the lower ends of the vertical guide rods 703 penetrate through the top of the U-shaped frame 5 and there are sliding bearings between the vertical guide rods 703 and the U-shaped frame 5 to ensure that the vertical guide rods 703 can slide relative to the U-shaped frame 5, and the vertical guide rods 703 guide the sliding of the mounting plate 702.

[0031] The horizontal adjustment component includes a horizontal pushing member 8, a connecting member and a positioning member. The horizontal pushing member 8 is also a cylinder. The horizontal pushing member 8 is installed on the right vertical plate 701 by bolts. The push rod of the horizontal pushing member 8 horizontally penetrates through the right vertical plate 701 and has a clearance fit with the right side plate.

[0032] The connecting member includes a fixed block 9 and two transition blocks 10. The fixed block 9 is vertically arranged between the two vertical plates 701, and the right side wall of the fixed block 9 is connected to the push rod of the horizontal pushing member 8 through a flange, and the fixed block 9 is driven to slide left and right by the horizontal pushing member 8. A guide rod 901 is horizontally arranged between the two vertical plates 701. The guide rod 901 horizontally penetrates through the fixed block 9 and the two vertical plates 701, and the guide rod 901 has an interference fit with the two vertical plates 701 and a small clearance fit with the fixed block 9 to ensure that the fixed block 9 can slide along the guide rod 901 and play a guiding role in the left and right sliding of the fixed block 9.

[0033] The positioning member in this embodiment includes a positioning rod 12 and a positioning plate 11. The positioning rod 12 is horizontally arranged on the positioning plate 11. The two transition blocks 10 are located between the positioning plate 11 and the fixed block 9. Specifically, the positioning rod 12 is arranged along the length direction of the cross plate 2 and has an interference fit with the positioning plate 11, and the diameter of the middle part of the positioning rod 12 in this embodiment is larger than that of the left part, so that a step is formed between the middle part and the left part of the positioning rod 12. When positioning the vehicle frame, the step abuts against the side wall of the vehicle frame, and the two positioning rods 12 clamp the vehicle frame inward.

[0034] The two transition blocks 10 each include a first connecting portion 101 and a second connecting portion 102. The first connecting portion 101 and the second connecting portion 102 of the same transition block 10 are integrally formed and are vertically L-shaped. The first connecting portion 101 of one of the transition blocks 10 is fixed to the front side wall of the fixed block 9 by bolts, and the first connecting portion 101 of the other transition block 10 is connected to the positioning plate 11 by bolts. The second connecting portions 102 of the two transition blocks 10 are in contact with each other. Two fixing holes 103 are provided on one of the second connecting portions 102, and a plurality of groups of mounting holes 104 are provided on the other second connecting portion 102 along the length direction of the slide rail 1. Each group of mounting holes 104 includes two mounting holes 104, and the two fixing holes 103 can be aligned with the two mounting holes 104 of any group. In this embodiment, bolts are used to pass through the aligned mounting holes 104 and fixing holes 103, and then nuts are used to lock them to connect the two second connecting portions 102.

[0035] The specific implementation process is as follows:

[0036] Before welding the vehicle frame, first place the vehicle frame between the positioning rods 12 of the two positioning units, and then start the lateral pushing member 8 to move the fixed block 9 towards the side close to the vehicle frame, so that the left part of the positioning rod 12 passes through the hole for fixing on the vehicle frame, and the vehicle frame is positioned by the step.

[0037] When it is necessary to adjust the position of the vehicle frame along the length direction of the vehicle frame, slide the insertion rod 4 upwards to above the positioning seat 3, then the cross plate 2 can be slid along the slide rail 1, and then insert the insertion rod 4 downwards into the aligned jack 301 again to quickly position the cross plate 2.

[0038] When it is necessary to adjust the height of the vehicle frame, start the vertical pushing member 6. Through the vertical pushing member 6, the mounting plate 702 can be slid upwards, driving the fixed seat upwards. Since the vehicle frame is located between the two positioning rods 12, the positioning rod 12 is driven upwards by the fixed seat to push the vehicle frame upwards; similarly, sliding the mounting plate 702 downwards through the vertical pushing member 6 can move the vehicle frame downwards.

[0039] When it is necessary to adjust the position of the vehicle frame along the width direction of the vehicle frame, start the lateral pushing member 8 on the left side. Through the lateral pushing member 8 on the left side, push the vehicle frame to push the fixed block 9 on the left side to the right, and at the same time, push the fixed block 9 on the right side to the right through the lateral pushing member 8 on the right side, then the whole vehicle frame can be moved to the right; similarly, pushing the fixed block 9 to the left through the lateral pushing member 8 can move the whole vehicle frame to the left. Therefore, the tooling in this embodiment can adjust the vehicle frame along the length direction, height direction and width direction of the vehicle frame to ensure that the vehicle frame can be aligned with the welding station.
