Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically an adjustable clamp for a radiator core brazing machine. Background Technology

[0002] In the prior art, radiator brazing machines are mainly used to weld the end cap of the radiator casing to the radiator core. The prior art mostly uses a conveyor frame to transport the radiator core, and a pressure measuring mechanism to position the radiator core. The entire radiator core is then transported to the brazing machine for welding by the conveyor mechanism. As long as the position of the radiator core in the brazing machine is set, the automatic welding of the radiator core can be basically completed.

[0003] For example, the prior art disclosed in the publication (announcement) number CN1701888A, "A fully automatic brazing machine for radiators", is equipped with a frame, a radiator positioning device, a welding device, a clamping device support arm, and a radiator clamping device, which can complete the automatic welding of the entire workpiece and greatly improve work efficiency.

[0004] For example, the "Bragging Machine for Copper-Aluminum Composite Radiators" disclosed in Publication No. CN1327998C includes a worktable for placing workpieces and a clamping device for pressing the workpieces onto the worktable. A lateral drive device is provided between the oscillating device and the welding torque, allowing the welding torque to move laterally forward and backward relative to the workpiece. This invention offers high efficiency, stable and reliable welding quality, and is suitable for automated welding of copper-aluminum composite radiators.

[0005] The above-mentioned technical solutions all include positioning mechanisms for fixing the radiator core. However, in brazing machines, the radiator core is placed directly on the conveyor belt using a shim structure. This setup is not stable enough and displacement can occur, which will seriously affect the welding quality, welding efficiency, and subsequent processes. Furthermore, different sizes of radiator cores require different clamps and shims for positioning and fixing. This necessitates the use of different clamping devices, increasing the overall cost of the device and making adjustment and installation very troublesome and inconvenient.

[0006] In addition, when the radiator core is placed on the conveyor belt, it cannot be positioned solely by the clamps on the conveyor belt. The radiator core itself also needs to be fixed. In existing technologies, it is usually not tied or directly tied with plastic buckles or other tools, which is very unsafe and unstable, and is very easy to cause safety accidents and affect welding efficiency and quality.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a reasonably structured and adjustable fixture for a radiator core brazing machine. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable fixture for a radiator core brazing machine; the technical solution is as follows:

[0009] An adjustable fixture for a radiator core brazing machine includes a brazing machine and a conveyor belt for transporting the radiator core into the brazing machine. The conveyor belt is equipped with four detachable and adjustable fixture base plates. The fixture base plates are provided with L-shaped side panels. The four side panels form a placement area, and the placement area formed by the four side panels is adapted to the size of the radiator core to be transported. The radiator core is placed in the four side panels and on the fixture base plate.

[0010] Furthermore, the radiator core is also equipped with several detachable binding and fixing clamps, which bind and fix the radiator core. The binding and fixing clamps are located in the middle of the radiator core and do not conflict with the positions of the clamp base plates on both sides.

[0011] Furthermore, the conveyor belt is made of metal, and conveyor sprockets are provided on both sides of the conveyor belt. The brazing machine is located above the conveyor belt, and the radiator core is fed into the brazing machine for welding via the conveyor belt.

[0012] Furthermore, the conveyor belt is provided with evenly distributed mounting holes, and each fixture base plate is provided with a mounting rod at its lower end. The mounting rod extends vertically downward and can be inserted into the mounting hole. A locking element is installed on the mounting rod to fix the fixture base plate to the conveyor belt.

[0013] Furthermore, the position of the mounting holes on the conveyor belt does not conflict with the position of the conveyor sprockets on both sides. When the mounting rod is locked in the mounting hole, it does not affect the drive of the conveyor sprockets on the conveyor belt.

[0014] Furthermore, each binding and fixing clamp includes two U-shaped frames, and each U-shaped frame has mounting holes at both ends. Mounting rods are provided at the mating ends of the two U-shaped frames, with both sides of the mounting rods extending into the corresponding mounting holes, thereby merging the two U-shaped frames into a single binding and fixing clamp. The radiator core is placed between the two U-shaped frames and is bound and fixed by the cooperation of the mounting rods and mounting holes.

[0015] Furthermore, the mounting rod is configured as a threaded rod, the fastener is configured as a fastening nut, and the mounting hole is configured as a threaded hole.

[0016] Furthermore, the two U-shaped frames are the same size, and a rotating block is set in the middle of the mounting rod. Both ends of the mounting rod are threaded, and the thread direction at both ends is set accordingly. After the rotating block in the middle is rotated, both sides of the mounting rod can be simultaneously screwed into the mounting hole, or simultaneously screwed out of the mounting hole.

[0017] Beneficial effects: This utility model has the following beneficial effects:

[0018] 1) In this device, the radiator core can be positioned by setting a clamp base plate on the conveyor belt and setting an L-shaped enclosure plate on the clamp base plate, thereby positioning the radiator core to enter the brazing machine, so that the radiator core can be welded in the brazing machine. The structure is reasonably designed.

[0019] 2) The position of the fixture base plate on the conveyor belt can be adjusted accordingly in this device, thereby adjusting the size of the placement area of ​​the radiator core, so as to adapt to the placement of radiator cores of different sizes, and can keep the welding position of the radiator core unchanged, without affecting the welding.

[0020] 3) In this device, the position of the fixture base plate is adjusted by setting mounting holes on the conveyor belt and mounting rods on the fixture base plate, and the material on the conveyor belt and the conveyor sprockets on both sides are set accordingly, which makes the structure reasonable;

[0021] 4) This device is also equipped with a binding and fixing clamp, which can be used to bind and fix the radiator core as a whole, and then conveniently place it on the clamp base plate. The structure is reasonably designed.

[0022] 5) The binding and fixing clamp of this device achieves docking installation by setting two U-shaped frames. The inner core of the radiator can be fixed by the cooperation of the threaded rod and the threaded hole, making the structure more reasonable and stable. Attached Figure Description

[0030] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0031] like Figure 1 and Figure 2 As shown, an adjustable fixture for a radiator core brazing machine includes a brazing machine 1 and a conveyor belt 3 for transporting the radiator core 2 into the brazing machine 1. Four detachable and adjustable fixture base plates 4 are installed on the conveyor belt 3. L-shaped surrounding plates 5 are provided on the fixture base plates 4. The four surrounding plates 5 form a placement area 6, and the placement area 6 formed by the four surrounding plates 5 is adapted to the size of the radiator core 2 to be transported. The radiator core 2 is placed in the four surrounding plates 5 and on the fixture base plate 4.

[0032] Furthermore, the inner core 2 of the radiator is also equipped with several detachable binding and fixing clamps 7. The inner core 2 of the radiator is bound and fixed by the binding and fixing clamps 7, and the position of the binding and fixing clamps 7 is located in the middle of the inner core 2 of the radiator, which does not conflict with the position of the clamp base plates 4 on both sides.

[0033] like Figure 6 As shown, the conveyor belt 3 is made of metal, and conveyor sprockets 8 are provided on both sides of the conveyor belt 3. The brazing machine 1 is located above the conveyor belt 3. The heat sink core 2 is fed into the brazing machine 1 for welding through the conveyor belt 3.

[0034] like Figure 3 and Figure 4 As shown, the conveyor belt 3 is provided with evenly distributed mounting holes 9, and each fixture base plate 4 is provided with a mounting rod 10 at its lower end. The mounting rod 10 extends vertically downward and can be inserted into the mounting hole 9. A locking member 11 is installed on the mounting rod 10, and the fixture base plate 4 is fixed to the conveyor belt 3 by the locking member 11.

[0035] The position of the mounting hole 9 on the conveyor belt 3 does not conflict with the position of the conveyor sprockets 8 on both sides. When the mounting rod 10 is locked in the mounting hole 9, it does not affect the drive of the conveyor sprockets 8 on the conveyor belt 3.

[0036] like Figure 5 As shown, each binding and fixing clamp 7 includes two U-shaped frames 12, and each U-shaped frame 12 has mounting holes 9 at both ends. Mounting rods 10 are provided at the mating ends of the two U-shaped frames 12. The two sides of the mounting rods 10 extend into the corresponding mounting holes 9, thereby merging the two U-shaped frames 12 into a whole binding and fixing clamp 7. The radiator core 2 is placed between the two U-shaped frames 12 and is bound and fixed by the cooperation of the mounting rods 10 and the mounting holes 9.

[0037] Mounting rod 10 is set as a threaded rod, fastener is set as a fastening nut, and mounting hole 9 is set as a threaded hole.

[0038] The two U-shaped frames 12 are the same size, and a rotating block 13 is provided at the middle position of the mounting rod 10. Both ends of the mounting rod 10 are threaded, and the thread direction at both ends is set accordingly. After the rotating block 13 in the middle is rotated, both sides of the mounting rod 10 can be simultaneously screwed into the mounting hole 9, or simultaneously screwed out of the mounting hole 9.

[0039] like Figure 1As shown, in the prior art, the welding of the radiator core 2 involves using a conveyor mechanism to transport the radiator core 2 to the brazing machine 1. The radiator core 2 can be directly welded by the brazing machine 1 once its position is set. Therefore, the radiator core 2 needs to be fixed on the conveyor belt 3 for transport. In this device, the position of the radiator core 2 is first determined by setting a clamp base plate 4 on the conveyor belt 3. Four clamp base plates 4 are provided, each detachably fixed to the conveyor belt 3. Each clamp base plate 4 also has a raised L-shaped surrounding plate 5. The area enclosed by the four surrounding plates 5 is the placement area 6 for the radiator core 2, and the size of this placement area 6 is definitely designed to fit the size of the radiator core 2. Therefore, the radiator core 2 can be directly placed within this area. However, due to the different sizes of the radiator core 2, the radiator core 2 may be affected by variations in its size and shape. The placement positions of the radiator core 2 are different, so the position of the fixture base plate 4 needs to be adjusted. However, the welding position inside the brazing machine 1 remains unchanged. In the technical solution of this device, the conveyor belt 3 is made of metal, such as a steel belt or an aluminum belt. At the same time, mounting holes 9 are provided on the conveyor belt 3. There are many mounting holes 9, and they are all evenly distributed. The lower end of the fixture base plate 4 is provided with mounting rods 10, which can be inserted into the mounting holes 9. Since there are many evenly distributed mounting holes 9, the placement position of the fixture base plate 4 can be adjusted by selecting different mounting holes 9. The placement positions of all four fixture base plates 4 can be adjusted. Therefore, the size of the middle placement area 6 can be adjusted by adjusting the position of the fixture base plate 4, thereby adapting to the placement of radiator cores 2 of different sizes.

[0040] Furthermore, since the conveyor belt 3 in this device is provided with mounting holes 9, the overall structure of the conveyor belt 3 and the drive mechanisms on both sides must also be set accordingly. In particular, the material of the conveyor belt 3 needs to be set to metal to have a certain degree of stability. The drive mechanisms on both sides are set to the form of conveyor sprockets 8 instead of conveyor rollers. Setting it to conveyor sprockets 8 will not affect the conveying of the conveyor belt 3 after the mounting rod 10 is installed. The length of the mounting rod 10 is not affected, and the mounting rod 10 can be set to be relatively long. In addition, in this device, the mounting holes 9 are set to threaded holes, the mounting rod 10 is set to threaded rods, and the locking part 11 is set to locking nuts, which can fix the mounting rod 10 relatively stably, thereby realizing the adjustment of the clamp base plate 4 and the structural stability.

[0041] In addition to the positioning and fixing within the radiator core 2, the radiator core 2 itself also needs to be bundled and fixed to facilitate placement within the base plate clamp. This device incorporates a bundling and fixing clamp 7 to specifically secure the radiator core 2. The bundling and fixing clamp 7 consists of two U-shaped frames 12, each with two ends and threaded holes. When the two U-shaped frames 12 are assembled together, threaded rods need to be installed at the corresponding end positions for connection. The threads in the threaded holes and threaded rods... To achieve the desired setup, rotating the rotating block 13 in the middle of the threaded rod will drive the threaded rod to rotate accordingly, causing it to rotate inward or outward simultaneously, thus achieving locking and unlocking. Then, the radiator core 2 is placed between the two U-shaped frames 12. The rotation of the threaded rod can lock and fix the radiator core 2 in the middle. After each radiator core 2 is equipped with multiple binding and fixing clamps 7, the overall structure will be very stable, thus achieving the fixation of the radiator core 2. It can also be placed on the clamp base plate 4 relatively easily. The overall structure is very reasonably set.

[0042] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
