Description

Technical Field

[0001] The invention relates to the field of condenser manufacturing, in particular to a multi-angle flipping air-conditioner condenser assembly welding workbench. Background Art

[0002] The condenser is one of the components of the refrigeration system and a type of heat exchanger. It can convert gas or vapor into liquid, transfer the heat in the heat pipe through the medium, conduct it to the end in a very fast manner, and then dissipate it into the nearby air through the cooling fins, thereby achieving rapid heat dissipation.

[0003] During the manufacturing process of the condenser, it is necessary to circulate and link the heat pipes buried between the fins to form a loop. This requires welding the ends of the heat pipes in the fins to the U-shaped elbows to connect the adjacent heat pipes. However, due to the operating space limitations caused by the high-density arrangement of the heat pipes and the influence of high temperature during welding, welding requires the elbows to be aligned, inserted and stabilized one by one before welding. Not only is the operation cumbersome, but the operating space is also limited. The welding quality will be negatively affected to a certain extent, affecting the life of the condenser.

[0004] Therefore, a novel multi-angle flip air conditioner condenser assembly welding workbench is needed to solve the above problems. Summary of the invention

The output end of the driving motor is connected to a threaded rod arranged parallel to the shift rail, and the threaded rod passes through the fixed clamping plate and the movable clamping plate for threaded transmission.

[0011] As a further solution of the present invention: a protruding strip of rubber is attached to the upper surface of the supporting plate on the side opposite to the fixed clamping plate and the movable clamping plate.

[0012] As a further solution of the present invention: a positioning tool is hinged on the fixed clamping plate, and the positioning tool is composed of an end piece, a sliding rod and a clamping slider. The end pieces are a group of two and are connected by a sliding rod. A clamping slider is slidably arranged on the sliding rod between the end pieces. The connection position between the end piece, the clamping slider and the sliding rod is locked by a screw assembly, and one side of the end piece is hinged to the fixed clamping plate to connect the positioning tool and the fixed clamping plate.

[0015] As a further solution of the present invention: the clamping part is composed of two cross-shaped arc structures, and the two arc structures are respectively arranged with a large and a small diameter.

Beneficial Effects

[0016] 1. The grounding platform of the present invention is connected with a column through a rotating shaft, and the top of the column is hinged with a hydraulically retractable supporting plate. An electric push rod is obliquely connected between the column and the supporting plate to adjust the hinge angle of the column and the supporting plate.

[0029] The present embodiment provides a multi-angle flip air-conditioning condenser assembly welding workbench, comprising a grounding platform 1, to which a column 3 is connected via a rotating shaft 2, a hydraulically retractable supporting plate 4 is hinged at the top of the column 3, an electric push rod 5 is obliquely connected between the column 3 and the supporting plate 4 to adjust the hinge angle of the column 3 and the supporting plate 4, and clamping mechanisms 7 for horizontally clamping the condenser are arranged on both sides of the supporting plate 4, and a positioning tool 75 for clamping and positioning the heat pipe elbow is arranged on the clamping mechanism 7.

[0030] Among them, the rotating shaft 2 includes a shaft disc 21 and a shaft column 23. The shaft disc 21 is provided with a 270° fan-shaped groove distributed axially. The top of the shaft disc 21 is rotatably connected to the shaft column 23. The shaft column 23 is fixedly welded to the bottom of the column 3. The bottom surface of the shaft column 23 is convexly provided with a 90° slider corresponding to the shaft disc groove. The angle distribution of the slider and the fan-shaped groove is utilized to limit the rotation angle of the support plate 4 to 180 degrees, so as to facilitate accurate adjustment of the angle for switching the welding direction and position.

[0031] Specifically, a group of limiting magnets 22 are correspondingly arranged on both end surfaces of the groove of the shaft disc 21 and the circumferential direction of the slider of the shaft column 23, and the angle of the supporting plate 4 is adsorbed and fixed by mutual adsorption of the magnets to limit the degree of freedom.

[0032] The clamping mechanism 7 includes a fixed clamping plate 71, a movable clamping plate 72 and a threaded rod 74. Both ends of the supporting plate 4 are welded with a transverse moving rail 6. The moving rail 6 is respectively fixedly connected with a fixed clamping plate 71 and slidably connected with a moving clamping plate 72. The fixed clamping plate 71 is fixed to one end of the moving rail 6, and a driving motor 73 is fixed on the side away from the moving clamping plate 72. The output end of the driving motor 73 is connected to a threaded rod 74 arranged parallel to the moving rail 6. The threaded rod 74 passes through the fixed clamping plate 71 and the moving clamping plate 72 for threaded transmission.

[0033] By horizontally clamping the movable clamping plate 72 and the fixed clamping plate 71, the end face of the condenser is avoided, and space is reserved for the position where the end face needs to be welded, which facilitates the installation and welding operations of the heat pipe elbow, prevents the end face heat pipe from being deformed by force, avoids the offset of the plug-in point of the heat pipe joint, and improves the tooling accuracy.

[0034] Specifically, the upper surface of the support plate 4 opposite to the fixed clamping plate 71 and the movable clamping plate 72 is affixed with protruding strips of rubber, which protect the side and bottom surfaces of the condenser fins to prevent the fins from being deformed by bumps and affecting the air circulation rate between the fins.

[0035] Specifically, the fixed clamping plate 71 is hinged with a positioning tool 75, which is composed of an end piece 751, a slide bar 752 and a clamping slider 753. The end pieces 751 are a group of two, connected by a slide bar 752, and a clamping slider 753 is slidably provided on the slide bar 752 between the end pieces 751. The connection position between the end piece 751, the clamping slider 753 and the slide bar 752 is locked by a screw assembly, wherein one side of the end piece 751 is hinged with the fixed clamping plate 71 to connect the positioning tool 75 with the fixed clamping plate 71;

[0036] By setting up the hinged and openable positioning fixture 75, the heat pipe elbows at corresponding points can be arranged and installed on the positioning fixture 75 in advance, and then the connection with the fin heat pipe can be achieved in one step by rotating the positioning fixture 75, thereby improving efficiency, and the heat pipe elbow can be clamped and fixed to ensure the accuracy of the connection angle during welding, thereby ensuring the uniformity and reliability of the weld. The positioning fixture 75 clamps and fixes the heat pipe elbow through the clamping slider 753. After the weld is cooled, the heat pipe elbow and the fin heat pipe can be directly separated by opening the positioning fixture 75 by utilizing the stable connection between the heat pipe elbow and the fin heat pipe.

[0037] Furthermore, the clamping slider 753 includes a guide frame 7531, a positioning bolt 7532 and a clamping piece 7533. The guide frame 7531 is a strip frame slidably connected to the slide rod 752. A positioning bolt 7532 is slidably provided on the inner side of the frame. An arc-shaped clamping piece 7533 can be fixed on the side of the positioning bolt 7532 facing the support plate 4 for clamping the heat pipe elbow. By sliding the positioning bolt 7532, the position of the clamping piece 7533 can be adjusted, and the sliding connection between the clamping slider 753 and the slide rod 752 can be combined to achieve full coverage of the heat pipe elbow installation point at the condenser end surface.

[0038] Furthermore, the positioning bolt 7532 is a two-piece structure connected by threads, and corresponding protruding strip guides are provided on both sides of the inner wall of the guide frame 7531. The setting of the two-piece threaded connection structure makes the fixing angle of the positioning bolt 7532 and the guide frame 7531 adjustable to meet the oblique installation requirements of the heat pipe elbow.

[0039] Furthermore, the clamping member 7533 is composed of two cross-shaped arc structures, and the two arc structures are respectively arranged with a large diameter and a small diameter. The arc structure with a small diameter is an incomplete circular ring with a distribution angle of 270°, and the arc structure with a large diameter is an arc plate with a circumferential cross section of 180° and a fan-shaped arc plate;

[0040] The circular buckle structure is used to clamp and fix the heat pipe elbow, while the arc-shaped plates on both sides fit the outer wall structure of the heat pipe elbow, limiting the angle of the heat pipe elbow within the circular structure to prevent angle deflection. It also stabilizes the heat pipe in the fin and improves the clamping accuracy.

[0041] When implementing the technical solution recorded in this embodiment, the length of the support plate 4 is adjusted in advance to be slightly longer than the length of the condenser according to the length of the condenser, the driving motor 73 is controlled to flip, and the movable clamping plate 72 of the clamping mechanism 7 is driven to move away through the threaded rod 74 to reserve space for clamping the condenser, and then the condenser is hoisted. After the hoisting is completed, the driving motor 73 is controlled to operate to drive the movable clamping plate 72 to clamp the condenser laterally from the side, and then the corresponding heat pipe elbows are snap-fitted and installed on the opened positioning fixture 75 clamping piece 7533 in sequence, and the clamping fixture 75 is closed. The heat pipe elbow on the clamping piece 7533 corresponds to the heat pipe plug-in on the condenser fin, and the operator welds and reinforces and seals the plug-in joint. The clamping angle of the condenser can be adjusted by rotating the rotating shaft 2 and adjusting the extension length of the electric push rod 5, and the welding position and angle are adjusted to facilitate the welding operation.
