Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and in particular to a welding fixture for a left-side suspension bracket with adjustable angle. Background Technology

[0002] The left suspension bracket plays a crucial role in the automotive engine mounting system. It is mainly responsible for connecting and supporting the left side of the engine, ensuring a stable connection between the engine and the vehicle body. This bracket is usually composed of multiple sheet-like structures, which are often tightly joined together by welding. In order to ensure the stability of each component during the welding process, the use of welding fixtures is indispensable.

[0003] Current welding fixtures typically only clamp individual parts of the bracket and can only adjust them horizontally or vertically. They can only move the fixed components. The angles between the various structures of the left suspension bracket often vary. During welding, it is often necessary to manually adjust each component or use pliers for clamping. Due to the low accuracy of manual adjustment, repeated adjustments are often required, which may waste a lot of time and result in low fixing and welding efficiency. In addition, manual adjustment may have certain errors, and pliers often need to be held in the hand, which may result in insufficient stability and cause the components to shake during welding. All of these factors may adversely affect the welding quality of the bracket.

[0004] Therefore, those skilled in the art have provided an angle-adjustable welding fixture for the left suspension bracket to solve the problems mentioned in the background art. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An angle-adjustable left suspension bracket welding fixture includes a main body, a first component, and a second component. A fixing mechanism is provided at the upper end of the main body near the middle position, and an adjustment mechanism is provided at the upper end of the main body near the perimeter. Clamping mechanisms are provided near both sides of the adjustment mechanism.

[0008] The main structure includes a base, a lifting platform is fixedly installed on the upper end of the base, a rotating disk is rotatably mounted on the upper end of the lifting platform, and a rotating motor is fixedly installed on the lower end of the lifting platform.

[0009] The fixing mechanism includes a bidirectional lead screw and two connecting rods. The bidirectional lead screw is threaded with connecting blocks near the front and rear ends. The upper ends of the two connecting blocks near the middle position on opposite sides are slidably fitted with telescopic blocks. The two telescopic blocks are fixedly fitted with locking blocks near both sides on opposite sides. The two connecting rods are slidably fitted with positioning blocks near both sides. The upper ends of the four positioning blocks are provided with multiple slots.

[0010] The adjustment mechanism includes a horizontal lead screw, an annular frame, and two limiting rods. The horizontal lead screw is threaded with a threaded plate. Rotating plates are rotatably provided on both sides of the upper end of the threaded plate. Fixed brackets are fixedly provided on both sides of the upper end of the annular frame. Vertical lead screws are rotatably sleeved inside the two fixed brackets near the front end.

[0011] Both clamping mechanisms include sliding blocks, and bolts are rotatably sleeved on the front ends of both sliding blocks. Limiting blocks are slidably set at the front and rear ends of both sliding blocks, and two clamping plates are sleeved on the outer surfaces of both bolts.

[0012] Furthermore, the first component is movably positioned at the upper end of the rotating disk near the center, and the two sides of the second component are respectively located between the four clamping plates. The bidirectional lead screw, the horizontal lead screw, and the two vertical lead screws are all controlled by a motor.

[0013] Furthermore, the lifting platform includes a support platform and two electric telescopic rods. The support platform is located at the upper end of the base, and the two electric telescopic rods are respectively fixedly installed inside the base near both sides. The upper ends of the two electric telescopic rods are fixedly connected to the lower end of the support platform, and the output end of the rotating motor is fixedly connected to the lower end of the rotating disk.

[0014] Furthermore, the front and rear ends of the bidirectional lead screw are rotatably sleeved on the rotating disk, the two telescopic blocks are connected to the two connecting blocks by multiple springs, the four positioning blocks are slidably disposed on opposite sides of the two connecting blocks, the two connecting rods are connected to the four positioning blocks by springs, and the middle positions of the opposite sides of the two connecting rods are fixedly connected to the two connecting blocks respectively.

[0015] Furthermore, the front and rear ends of the horizontal lead screw are rotatably sleeved on the base, the front end of the annular frame is rotatably connected to the upper end of the base, and the upper ends of the two rotating plates are rotatably connected to the lower end of the annular frame.

[0016] Furthermore, the front and rear ends of the two limiting rods are respectively slidably sleeved on the front and rear ends of the two fixed frames, and the front ends of the two limiting rods are respectively threaded onto the two vertical lead screws.

[0017] Furthermore, the two sliding blocks are respectively slidably sleeved on the two limiting rods, and the four limiting blocks are respectively engaged with the two limiting rods.

[0018] Furthermore, two of the four clamping plates near the front end are threaded onto the outer surfaces of the two bolts, and two of the four clamping plates near the rear end are rotatably fitted onto the outer surfaces of the two bolts near the rear end.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model proposes an angle-adjustable left-side suspension bracket welding fixture, which includes a main body mechanism and a fixing mechanism. The fixing mechanism includes a positioning block that can quickly fix the component. Under the action of a bidirectional lead screw, the positioning block can fix the component from the front and rear ends. Simultaneously, the telescopic block is compressed and retracts inward, releasing the positioning block from locking it. Under the action of a spring, the component is fixed from both sides. Then, a locking block re-locks the position of the positioning block, achieving rapid fixing of the component. Furthermore, the rotating disk can drive the entire fixing mechanism to rotate, allowing for timely angle adjustment of the first component. This ensures both rapid fixing of the component and meets the need to change the component angle at any time during welding, making it convenient and precise, greatly improving welding efficiency and quality.

[0021] 2. This utility model proposes an angle-adjustable welding fixture for a left suspension bracket. The welding fixture is equipped with an adjustment mechanism and a clamping mechanism. The clamping mechanism can fix the component through a clamping plate. The clamping mechanism is directly connected to the fixture to ensure the stability of the component. In addition, the adjustment mechanism drives the rotation of the rotating plate through a lead screw, thereby adjusting the angle of the rotating frame and finally achieving precise adjustment of the angle of the second component. This adjustment process is both stable and precise, ensuring the stability of the component during the welding process and effectively guaranteeing the welding quality of the left suspension bracket.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 An embodiment of this utility model provides: an angle-adjustable left suspension bracket welding fixture, including a main body 1, a first component 5 and a second component 6. A fixing mechanism 2 is provided at the upper end of the main body 1 near the middle position. An adjustment mechanism 3 is provided at the upper end of the main body 1 near the four sides. A clamping mechanism 4 is provided at both sides of the adjustment mechanism 3. The first component 5 is movably disposed at the upper end of the rotating disk 103 near the middle position. The two sides of the second component 6 are respectively located between the four clamping plates 404.

[0032] Specifically, the main body mechanism 1 is the main structure of the welding fixture, supporting other structures and driving the rotation of the fixing mechanism 2. Component 1 5 and Component 2 6 are both components of the left suspension bracket. The fixing mechanism 2 can fix Component 1 5. The adjusting mechanism 3 can adjust the welding angle between Component 2 6 and Component 1 5. The clamping mechanism 4 can clamp and fix Component 2 6.

[0033] Reference Figure 2 , Figure 5 , Figure 6The main structure 1 includes a base 101, a lifting platform 102 is fixedly installed on the upper end of the base 101, a rotating disk 103 is rotatably mounted on the upper end of the lifting platform 102, and a rotating motor 104 is fixedly installed on the lower end of the lifting platform 102.

[0034] The lifting platform 102 includes a support platform and two electric telescopic rods. The support platform is located at the upper end of the base 101. The two electric telescopic rods are fixedly installed inside the base 101 near both sides. The upper ends of the two electric telescopic rods are fixedly connected to the lower end of the support platform. The output end of the rotating motor 104 is fixedly connected to the lower end of the rotating disk 103.

[0035] Specifically, the base 101 is the main support structure of the welding fixture, the lifting platform 102 can adjust the height of the first component 5, and the rotating disk 103 can change the angle of the first component 5. These can meet the welding requirements of different angles between components, and the rotating motor 104 can drive the rotating disk 103 to rotate.

[0036] Reference Figure 5 , Figure 6 The fixing mechanism 2 includes a bidirectional lead screw 201 and two connecting rods 207. The bidirectional lead screw 201 is threaded with connecting blocks 202 near the front and rear ends. The upper ends of the two connecting blocks 202 near the middle position on opposite sides are slidably fitted with telescopic blocks 203. The two telescopic blocks 203 are fixedly fitted with locking blocks 204 near both sides on opposite sides. The two connecting rods 207 are slidably fitted with positioning blocks 205 near both sides. The upper ends of the four positioning blocks 205 are provided with multiple slots 206.

[0037] The front and rear ends of the bidirectional lead screw 201 are rotatably sleeved on the rotating disk 103. The two telescopic blocks 203 and the two connecting blocks 202 are connected by multiple springs. The four positioning blocks 205 are slidably disposed on the opposite side of the two connecting blocks 202. The two connecting rods 207 are connected to the four positioning blocks 205 by springs. The middle position of the opposite side of the two connecting rods 207 is fixedly connected to the two connecting blocks 202. The bidirectional lead screw 201, the horizontal lead screw 301 and the two vertical lead screws 307 are all controlled by a motor.

[0038] Specifically, the bidirectional lead screw 201 drives the two connecting blocks 202 to move in opposite directions. The connecting blocks 202 can connect the two positioning blocks 205 together to ensure their synchronous movement. At the same time, it can allow the two positioning blocks 205 to adjust their positions along the connecting blocks 202. The telescopic block 203 extends and retracts under the spring force and the squeezing action of the first component 5. The locking block 204 also moves accordingly. The engagement of the locking block 204 with the locking groove 206 can realize the positioning function of the positioning block 205. When the telescopic block 203 is not subjected to external force, it is located in the middle of the two positioning blocks 205 and plays a locking role. When the telescopic block 203 is subjected to external force and contracts, the two positioning blocks 205 will move towards each other under the action of the spring to clamp the first component 5.

[0039] Reference Figure 2-4 The adjusting mechanism 3 includes a horizontal lead screw 301, an annular frame 304 and two limiting rods 305. The horizontal lead screw 301 is threaded with a threaded plate 302. The upper end of the threaded plate 302 is rotatably provided with rotating plates 303 near both sides. The upper end of the annular frame 304 is fixedly provided with fixing brackets 306 near both sides. The two fixing brackets 306 are rotatably fitted with vertical lead screws 307 inside near the front end.

[0040] The front and rear ends of the horizontal lead screw 301 are rotatably sleeved on the base 101. The front end of the annular frame 304 is rotatably connected to the upper end of the base 101. The upper ends of the two rotating plates 303 are rotatably connected to the lower end of the annular frame 304. The front and rear ends of the two limiting rods 305 are slidably sleeved on the front and rear ends of the two fixed frames 306 respectively. The front ends of the two limiting rods 305 are threadedly sleeved on the two vertical lead screws 307 respectively.

[0041] Specifically, the rotation of the horizontal lead screw 301 can drive the threaded plate 302 to move, which in turn drives the rotating plate 303 to rotate. When the annular frame 304 is supported by the rotating plate 303, it will flip over, that is, the angle of the second component 6 is adjusted. The rotation of the vertical lead screw 307 can drive the upper end of the limiting rod 305 to slide. The upper end of the limiting rod 305 is provided with multiple limiting grooves, which, together with the limiting block 403, can position the clamping mechanism 4.

[0042] Reference Figure 4 Both clamping mechanisms 4 include sliding blocks 401, and bolts 402 are rotatably sleeved on the front ends of both sliding blocks 401. Limiting blocks 403 are slidably set at the front and rear ends of both sliding blocks 401, and two clamping plates 404 are sleeved on the outer surfaces of both bolts 402.

[0043] Two sliding blocks 401 are slidably sleeved on two limiting rods 305 respectively, four limiting blocks 403 are respectively engaged with two limiting rods 305, two of the four clamping plates 404 near the front end are threadedly sleeved on the outer surface of two bolts 402 respectively, and two of the four clamping plates 404 near the rear end are rotatably sleeved on the outer surface of two bolts 402 near the rear end.

[0044] Specifically, the sliding block 401 can slide along the limiting rod 305, the rotation of the bolt 402 can drive the movement of the clamping plate 404 near the front end, and the four clamping plates 404 are provided with anti-slip textures on opposite sides of each other. The four clamping plates 404 can clamp and fix the second component 6, and the limiting block 403 can slide up and down along the outer surface of the sliding block 401.

[0045] Working principle: When using this welding fixture, place component 5 on the upper end of the rotating disk 103, start the bidirectional lead screw 201, and the two connecting blocks 202 move towards the middle. When the telescopic block 203 is squeezed by component 5, the telescopic block 203 retracts slightly inward, and the positioning block 205 releases the locking of the telescopic block 203. Under the action of the internal spring, the positioning blocks 205 on both sides move closer to component 5, and the telescopic block 203 continues to be squeezed and retracts inward. The locking block 204 engages with the locking groove 206 to lock the position of the positioning block 205.

[0046] Then, start the vertical screw 307, adjust the clamping mechanism 4 to a suitable height, place the second component 6 between the front and rear clamping plates 404, press the rear end face of the second component 6 against the front end of the clamping plate 404 near the rear end, rotate the bolt 402, drive the clamping plate 404 near the front end to move backward, so that the clamping plate 404 firmly fixes the second component 6.

[0047] Next, start the horizontal lead screw 301, the threaded plate 302 moves backward, the lower end of the rotating plate 303 moves backward, causing the rotating plate 303 to flip, and the annular frame 304 flips forward until the second component 6 is adjusted to a suitable angle. Then slide the limit block 403 upward, so that the sliding block 401 slides along the limit rod 305 to adjust the position. Slide the limit block 403 downward to engage with the limit groove on the limit rod 305, stabilizing the clamping mechanism 4 in a suitable position. Finally, start the lifting platform 102 so that the upper end of the first component 5 contacts the lower end of the second component 6, and welding can be carried out.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
