Description

Technical Field

[0001] This utility model relates to the field of cooler processing technology, specifically to a vacuum brazing fixture for aluminum oil coolers. Background Technology

[0002] The vacuum brazing fixture for aluminum oil coolers ensures stable positioning and tight fit of each component during high-temperature brazing through precise positioning, uniform clamping, and reliable support. Its scientific material and structural design not only guarantees welding quality but also facilitates efficient and rapid vacuum brazing.

[0003] The existing patent document with application number 202322673293.7 provides a special fixture for vacuum brazing, which belongs to the field of vacuum brazing technology. This vacuum brazing fixture includes a fixed base with feet mounted at each of the four corners of its bottom. The fixed base has a moving groove inside, with a lead screw mounted on one side of the groove. A guide rod is connected to the side of the moving groove away from the lead screw. A motor is mounted on the outside of the fixed base, and the motor's output is connected to the lead screw drive. A moving plate is connected to the top of a pair of sliders, and a clamping mechanism is located on the top of the moving plate. The clamping mechanism includes a pair of moving seats. Second mounting seats are mounted on both sides of the fixed base, and each pair of second mounting seats has a smoke removal mechanism inside. The smoke removal mechanism includes a pair of smoke extractors. The clamping mechanism facilitates the clamping and fixing of the workpiece, while the smoke removal mechanism removes the fumes generated during production, preventing environmental impact. Although the above application has many advantages, it still has the following shortcomings: During the clamping process of the cooler, the extraction angle of the delivery pipe cannot be adjusted. It requires two steps—clamping and then repositioning the clamped object—to properly align the delivery pipe with the brazing area for extraction, which greatly reduces the ease of operation. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum brazing fixture for aluminum oil coolers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum brazing fixture for an aluminum oil cooler, comprising a base, a worktable fixedly connected to the top of the base, a bidirectional lead screw rotatably connected to the worktable, and symmetrically arranged clamping blocks slidably connected to the worktable;

[0006] The base is equipped with an extraction mechanism, which includes an air collection box, two support seats, and multiple guide rods. Symmetrically arranged flexible delivery pipes are fixedly connected to the air collection box. A rigid delivery pipe is fixedly connected to one end of each flexible delivery pipe. A connecting rod is fixedly connected to each rigid delivery pipe. An extraction head is fixedly connected to one end of each rigid delivery pipe. Rotating rods are rotatably connected to each support seat. A connecting rod is fixedly connected to each rotating rod at a position corresponding to the inside of the support seat. A limit gear is fixedly connected to each rotating rod at a position adjacent to the connecting rod. Each pair of opposing guide rods is slidably connected to a toothed block. A spring is fixedly connected to the bottom end of each toothed block at a position corresponding to the guide rod.

[0007] Preferably, one end of the bidirectional lead screw is fixedly connected to a rotating handle, and the bidirectional lead screw is threadedly connected to the two clamping blocks at the corresponding positions inside the worktable.

[0008] Preferably, the gas collection box is fixedly connected to one side of the top of the base, the support base is symmetrically fixedly connected to the top of the base near the middle, and the guide rods are fixedly connected in pairs to the top of the base on the side corresponding to the support base.

[0009] Preferably, all the connecting rods are rotatably connected to their corresponding connecting rods.

[0010] Preferably, the limiting gears are all meshed with the corresponding tooth blocks, and the bottom ends of the springs are all fixedly connected to the top end of the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting the extraction mechanism, the angle of the two extraction heads can be directly adjusted without having to move the object to be clamped away from the extraction head. After the angle of the extraction head is adjusted, the object clamping operation can be performed directly. It is not only highly convenient to operate, but also highly practical.

[0017] 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.

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] Example 1: Vacuum brazing fixture for aluminum oil cooler, including base 1, worktable 5 fixedly connected to the top of base 1, bidirectional lead screw 3 rotatably connected to worktable 5, symmetrically arranged clamping blocks 4 slidably connected to worktable 5, rotating handle fixedly connected to one end of bidirectional lead screw 3, and threaded connection between bidirectional lead screw 3 and two clamping blocks 4 at corresponding positions inside worktable 5.

[0020] In use, place the cooler between the two clamping blocks 4, and rotate the double-acting screw 3 by turning the handle. The double-acting screw 3 will drive the two clamping blocks 4 to move towards the middle at the same time to clamp the cooler. After clamping, it can be brazed by a vacuum brazing machine.

[0021] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a extraction mechanism 2 on the base 1, the extraction mechanism 2 including an air collection box 21, two support seats 22 and multiple guide rods 23, a symmetrically arranged soft conveying pipe 24 fixedly connected to the air collection box 21, a hard conveying pipe 25 fixedly connected to one end of each soft conveying pipe 24, a connecting rod 26 fixedly connected to each hard conveying pipe 25, an extraction head 27 fixedly connected to one end of each hard conveying pipe 25, a rotating rod 28 rotatably connected to each support seat 22, a connecting rod 29 fixedly connected to each rotating rod 28 at a position corresponding to the inside of the support seat 22, a limit gear 201 fixedly connected to each rotating rod 28 at a position adjacent to the connecting rod 29, and a toothed block 202 slidably connected to each pair of opposing guide rods 23, and a spring 203 fixedly connected to the bottom end of the toothed block 202 at a position corresponding to the guide rod 23.

[0022] The air collection box 21 is fixedly connected to one side of the top of the base 1. The support seat 22 is symmetrically fixedly connected to the top of the base 1 near the middle. The guide rods 23 are fixedly connected to the top of the base 1 on the side corresponding to the support seat 22. The linkage rods 29 are rotatably connected to the corresponding connecting rods 26. The limit gears 201 are meshed with the corresponding tooth blocks 202. The bottom of the springs 203 is fixedly connected to the top of the base 1.

[0023] Before fixing the cooler, connect one side of the air collection box 21 to the external power connection pipe. The connecting rod 29 can then be rotated directly. The connecting rod 29 will drive the rotating rod 28 to rotate, which in turn drives the limiting gear 201 to rotate. The rotation of the limiting gear 201 will compress the toothed block 202. Under this pressure, the toothed block 202 will move downwards under the guidance of the guide rod 23. Simultaneously, the toothed block 202 will also compress and contract the spring 203. During the rotation of the limiting gear 201, the toothed block 202 will repeatedly bounce up and down due to the elastic force of the spring 203. At the same time, the rotation of the connecting rod 29 will act on the connecting rod 26. At this time, the connecting rod 26 rotates towards the base 1 along with one end of the connecting rod 29. The connecting rod 26 will drive the rigid conveying tube 25 and the extraction head 27 to rotate together. The rotation of the rigid conveying tube 25 will act on the flexible conveying tube 24, causing the flexible conveying tube 24 to undergo adaptive deformation. Then, the rigid conveying tube 25 and the extraction head 27 can be rotated to the appropriate position. The spring 203 and the tooth block 202 can provide positional stability for the limit gear 201, the rotating rod 28 and the connecting rod 29. At this time, the cooler can be fixed normally. During the fixing process, there is no need to move the cooler away from the extraction head 27, which makes the operation more convenient.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
