Description

Technical Field

[0001] The utility model relates to the technical field of condenser assembly, in particular to a condenser flat tube assembly fixture. Background Art

[0002] The automotive air conditioning condenser is an important component used to cool and condense the refrigerant in the air conditioning system. It is usually installed at the front of the vehicle, similar to the position of the radiator, and cools the refrigerant through heat exchange with the surrounding air.

[0003] The automobile air conditioning condenser includes two headers and flat tubes installed between the headers. In the header, the cooling medium will be evenly distributed to the connected flat tubes so that the cooling process can be carried out in the entire condenser. The function of the flat tubes is to exchange heat with the surrounding air through their surface, thereby cooling the cooling medium transported through the header.

[0004] When producing automotive air-conditioning condensers, flat tube and collecting tube assembly equipment is required.

[0005] The applicant previously disclosed a car air-conditioning condenser core assembly device, with the publication (announcement) number: CN214722124U, which includes a base, a fixed base, a flat tube slot, and a sliding base. The top of the sliding base is provided with a header slot for the header to be engaged from top to bottom, and one side of the sliding base is provided with a through slot. The two sliding bases are driven by a driving mechanism to move relative to each other, and the base is provided with a clamping mechanism for clamping the flat tubes engaged in the flat tube slots. By sequentially inserting multiple flat tubes into multiple flat tube slots, and then inserting two headers into two header slots respectively, and then driving the two sliding bases to move synchronously through the driving mechanism, the two ends of the flat tubes can be synchronously inserted into the flat tube slots on the two headers, so that multiple flat tubes can be synchronously installed on the headers.

[0006] The above device has the following problems when used: when assembling the header, it is necessary to ensure that all the flat tubes on the fixing seat are flush. Figure 1 As shown, when workers place the flat tubes on the fixed seat, it is difficult for the flat tubes to be completely placed flush, and multiple flat tubes are staggered. At this time, in order to ensure that the collecting pipe is accurately assembled on the flat tubes, the workers need to align the staggered flat tubes one by one. This leveling method requires manual operation by workers, which is prone to operational errors, resulting in problems in the subsequent assembly of the collecting pipe and the flat tubes.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 2-5 A condenser flat tube assembly fixture includes a frame and a base 8 fixed on the frame. A plurality of spaced stoppers 7 are fixedly connected to the upper portion of the base 8. A flat tube placement gap 6 for placing flat tubes 5 is provided between adjacent stoppers 7. The fixture includes a clamping component and a leveling component. The clamping component can lock or unlock the relative position of the flat tube 5 and the stopper 7. The leveling component can align multiple flat tubes 5 when the flat tube 5 and the stopper 7 are in an unlocked state.

[0024] When the device is used, the clamping assembly is first in an unlocked state, and the flat tubes are placed in the flat tube placement seams 6 according to their approximate positions. At this time, the distribution of the flat tubes is not completely neat, and then the flat tubes are neatly distributed through the leveling assembly. After that, the clamping assembly is again in a locked state, so that the aligned flat tubes are locked in position with the stopper 7, and then the subsequent assembly process of the collecting pipe and the flat tubes can be carried out. The flat tube leveling of the device is completed mechanically, with a low error rate, and after the flat tubes are aligned, the relative position of the flat tubes and the base can be fixed, which is convenient for subsequent processes.

[0025] refer to Figure 1The leveling assembly includes a power telescopic member 1 which is vertically arranged and fixed to the frame. The telescopic end of the power telescopic member 1 is fixedly connected to a bracket 2, and a first push plate 3 is fixedly connected to the bottom of the bracket 2. The bottom end of the first push plate 3 has a first inclined surface 4 that can push the flat tube 5 to move. After the flat tubes are placed in the flat tube placement seam 6 according to the approximate orientation, the staggered spacing difference between the flat tubes needs to be within the range of the downward projection of the first inclined surface 4. The first push plate 3 is driven downward by the power telescopic member 1, and the staggered flat tubes are pushed to one side to be neatly arranged by using the first inclined surface 4. As an implementation method, when the first inclined surface 4 moves to the top position, the flat tube 5 is located in the middle of the base. As an implementation method, the inclination angle of the first inclined surface 4 is 30°-45°, and the downward projection width of the first inclined surface 4 is 1 cm-6 cm. Similarly, when the flat tubes are initially placed, the maximum distance difference between the flat tubes does not exceed 1 cm-6 cm, and needs to be within the downward projection range of the first inclined surface 4.

[0026] As an embodiment, the clamping assembly includes a movable seat 9 slidably connected to the frame, the sliding direction of the movable seat 9 is perpendicular to the flat tube 5, a plurality of spaced abutment plates 13 are fixedly connected to the upper part of the movable seat 9, a support block 10 fixed to the frame is provided at one end of the movable seat 9, a thrust spring 11 is installed between the support block 10 and the movable seat 9, and the clamping assembly includes a vertically arranged second push plate 16, the second push plate 16 is arranged parallel to the flat tube 5 and is located on the side of the movable seat 9 away from the thrust spring 11, the top end of the second push plate 16 is fixed to the bracket 2, and the bottom end of the second push plate 16 has a force capable of pushing the movable seat 9 to move When the second inclined surface 15 moves and the powered telescopic member 1 drives the second push plate 16 to move downward, the second inclined surface 15 is used to push the movable seat to extrude the thrust spring 11, so that the abutment plate 13 is away from the flat tube 5, thereby unlocking the flat tube and the block. At this time, the flat tube is in an unlocked state, and then the bracket 2 continues to move downward. At this time, the first inclined surface 4 of the first push plate 3 pushes the flat tube to align. After alignment, the powered telescopic member 1 drives the bracket 2 to move upward, and the second push plate 16 is away from the movable seat 9. The thrust spring 11 pushes the abutment plate 13 on the movable seat 9 to abut against the flat tube 5, so that the flat tube is clamped between the abutment plate 13 and the block 7.

[0027] In order to ensure the stability of clamping, two bases 8 are provided, and the movable seat 9 is located between the two bases 8 .

[0028] For further reference, Figure 3 A slideway 14 is provided on one side of the base 8 close to the movable seat 9 , and sliders 12 are fixedly connected or integrally formed on both sides of the movable seat 9 , and the sliders 12 are slidably connected in the slideway 14 .
