Description

Technical Field

[0001] This utility model relates to a welding fixture for bending the outer shell of a vacuum booster. Background Technology

[0002] A vacuum booster is a device used to enhance the performance of a motor vehicle's braking system. It effectively amplifies the force applied by the driver when pressing the brake pedal, multiplying the pressure output by the master cylinder, thereby improving the braking efficiency of the braking system and enabling the vehicle to decelerate or stop more quickly and effectively. The vacuum booster's housing has a bent tube for connecting the booster and the vacuum source. This bent tube is typically welded to the booster. During the welding process, ensuring the stable placement of both the bent tube and the vacuum booster housing is crucial to guarantee welding quality and prevent positional deviations. Therefore, developing a welding fixture for the bent tube that ensures stable placement of the bent tube and the vacuum booster housing during welding is of significant practical importance.

[0021] See Figures 1 to 8 The illustrated fixture for welding bent tube housings of vacuum boosters includes a base plate 11. The base plate 11 has a clamping assembly 12 and a protective plate 13. The protective plate 13 is disposed on one side of the clamping assembly 12 and has a pressing assembly 14. The clamping assembly 12 includes a slide rail 17, which is fixedly mounted on the base plate 11. Two clamping blocks 18 are slidably mounted on the slide rail 17. Each clamping block 18 has a first boss 19 and a second boss 20. A clamping hole 21 is located on one side of the second boss 20. The slide rail 17, clamping blocks 18, first boss 19, and second boss 20 are all made of brass and have good electrical conductivity. The first boss 19 is fixedly mounted on the clamping block 18, and the second boss 20 is fixedly mounted on the first boss 19. The clamping hole 21 is a semi-circular hole. The two clamping holes 21 are joined together to form a circular hole that can clamp the bent pipe. Each clamping block 18 has a locking bolt 22 on both sides. The end of the locking bolt 22 abuts against the side of the slide rail 17. The clamping block 18 has a threaded hole corresponding to the locking bolt 22. One end of the locking bolt 22 passes through the threaded hole and abuts against the side of the slide rail 17, so that the slide rail 17 and the clamping block 18 are locked. A U-shaped bracket plate 15 is provided on one side of the clamping assembly 12. Two mounting pieces 16 are provided on the U-shaped bracket plate 15. The mounting pieces 16 are connected to the base plate 11 by bolts. The U-shaped bracket plate 15 stands vertically on the base plate 11. The mounting pieces 16 are fixed at the edge of the U-shaped bracket plate 15. The mounting pieces 16 are connected to the base plate 11 by bolts so that the U-shaped bracket plate 15 can be stably installed on the base plate 11.

[0022] Furthermore, the clamping assembly 14 includes a fixing plate 27, which is fixedly mounted on the protective plate 13. A vertical rod 28 is fixedly mounted on the fixing plate 27, and a lifting cylinder 29 is provided on the vertical rod 28. The lifting cylinder 29 is slidably mounted on the vertical rod 28. The vertical rod 28 can adjust the height of the mounting block 30 and the sliding rod 31 by sliding along the lifting cylinder 29. A mounting block 30 is fixed on one side of the lifting cylinder 29. A circular hole is provided on the mounting block 30, and a sliding rod 31 is provided in the circular hole. A pressure plate 32 is provided at one end of the sliding rod 31. The sliding rod 31 is slidably mounted in the circular hole on the mounting block 30, and the pressure plate 32 is fixed to one end of the sliding rod 31.

[0023] Furthermore, the side wall of the lifting cylinder 29 is provided with a second locking bolt 33, one end of which abuts against the upright 28. The side wall of the lifting cylinder 29 is provided with a threaded hole corresponding to the second locking bolt 33. One end of the second locking bolt 33 passes through the threaded hole and abuts against the upright 28, thereby locking the lifting cylinder 29 and the upright 28. The side wall of the round hole on the mounting block 30 is provided with a third locking bolt 34, one end of which abuts against the sliding rod 31. The side wall of the round hole on the mounting block 30 is provided with a threaded hole corresponding to the third locking bolt 34. One end of the third locking bolt 34 passes through the threaded hole and abuts against the sliding rod 31, thereby locking the mounting block 30 and the sliding rod 31.

[0024] Furthermore, electrode post 1 23 and electrode post 24 are respectively provided on both sides of the clamping block 18. A wire 25 is connected between the electrode posts 23 on the two clamping blocks 18, and a wire 26 is provided on the electrode posts 24 on the two clamping blocks 18. The base plate 11 has through holes corresponding to the electrode posts 24. The electrode posts 24 pass through the through holes and are connected to the welding power source. The two clamping blocks 18 are connected through the electrode posts 23 and the wire 25 to form a closed loop. When the bent tube is clamped in the circular hole formed by the two clamping holes 21, the bent tube is electrically connected to the welding power source.

[0025] Furthermore, the protective plate 13 is arc-shaped, and both ends of the protective plate 13 are connected to the base plate 11 by bolts. The protective plate 13 is fixedly installed on one side of the clamping assembly 12. The wire 25 between the two clamping blocks 18 is surrounded by the protective plate 13, thereby forming a protection on one side of the wire 25 by the protective plate 13, making the wire 25 less likely to be touched casually.

[0026] The working principle of this utility model is as follows: When welding the bent tube to the vacuum booster housing, the vacuum booster housing is placed on the U-shaped support plate 15, with the edge of the housing resting on the clamping block 18. The bent tube is placed between the two clamping holes 21. The locking bolt 22 on the clamping block 18 is loosened to release the lock between the slide rail 17 and the clamping block 18. Then, the clamping block 18 is slid along the slide rail 17, causing the first boss 19 and the second boss 20 to move accordingly until the clamping holes 21 on the two second bosses 20 form a circular hole, in which the mesh tube is clamped. The locking bolt 22 is then tightened to lock the clamping block 18 and the slide rail 17 again, thus stably clamping the bent tube. Then, the vacuum booster housing placed on the U-shaped support plate 15 is pushed appropriately so that the welded joint between the bent tube and the side of the housing is close together. Loosen the second locking bolt 33 to release the lock between the upright 28 and the lifting cylinder 29. Slide the lifting cylinder 29 along the upright 28 to move the mounting block 30, the slide rod 31, and the pressure plate 32, thereby adjusting the height of the pressure plate 32. Loosen the third locking bolt 34 to release the lock between the mounting block 30 and the slide rod 31. Push the slide rod 31 to bring the pressure plate 32 closer to the vacuum booster housing, allowing the pressure plate 32 to press against the housing. Then tighten the second locking bolt 33 and the third locking bolt 34 to lock the upright 28 and the lifting cylinder 29, and the mounting block 30 and the slide rod 31, so that the pressure plate 32 stably presses against the vacuum booster housing, allowing the vacuum booster housing to be stably placed on the U-shaped support plate 15. At this point, both the bend and the vacuum booster housing are stably placed, and then welding can be performed using a welding machine.

[0027] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
