[0014] The present utility model will be further described below with reference to the drawings.

[0015] As shown in the attached Figures 1-3 For the welding tooling for the cabinet door hinge described above, it includes a main body frame 1, the main body frame 1 is placed on the end face parallel to the opening side of the cabinet body, a plurality of positioning components 5 are arranged in a vertical direction on the main body frame 1, the positioning component 5 includes a main body positioning module 2 and a hinge positioning module 3, the main body positioning module 2 and the hinge positioning module 3 are respectively located on both sides of the main body frame 1, and the main body positioning module 2 and the hinge positioning module 3 are transversely corresponding.

[0016] In this solution, multiple groups of positioning components 5 are integrally installed on the main body frame, and each group of positioning components 5 is used for positioning and installing a cabinet door hinge. In the positioning component 5, the main body positioning component 5 is used to cooperate with the positioning holes on the cabinet body, so that the relative position between the main body frame and the opening of the cabinet body is fixed. Since the hinge positioning module and the main body positioning module are transversely corresponding, the relative position between the hinge positioning module and the cabinet opening is fixed. The hinge positioning module is used to position and install the cabinet door hinge relative to the main body frame, so that the hinge is fixed and attached to one side of the cabinet opening. Multiple positioning components 5 can position and attach multiple cabinet door hinges relative to the cabinet body, facilitating the rapid welding of multiple cabinet door hinges, improving the welding efficiency, and ensuring the relative position between multiple cabinet door hinges is fixed and the position is accurate, so as to avoid interference in the opening and closing of adjacent cabinet doors after installing the cabinet doors.

[0017] The hinge positioning module 3 is provided with a positioning block 31. The positioning block 31 is provided with a cabinet body fitting surface 32 and a hinge fitting surface 33. When the cabinet body fitting surface 32 is in contact with the end face of the opening side of the cabinet body, the hinge is in contact with the welding surface on the cabinet body. To meet the positioning and installation of hinges on different cabinet body structures, the structure of the opening side end face of the cabinet body is adapted through the positioning block. For example, when there is a height difference between the opening end face and the hinge welding surface, the cabinet body fitting surface 32 not only plays a positioning role but also a limiting role, ensuring that the hinge is just in close contact with the welding surface and guaranteeing the welding accuracy and quality.

[0018] The hinge fitting surface 33 is provided with a hinge positioning pin 34. The hinge positioning pin 34 is correspondingly inserted into the positioning hole on the hinge 4. A limiting block 35 is arranged on the outer side of the positioning pin 34, and the limiting block 35 is in contact with the side surface of the hinge 4. A single positioning pin is used to position the hinge structure, and the limiting block is used to restrict the rotation of the hinge structure relative to the hinge positioning pin.

[0019] The limiting block 35 slides close to or away from the hinge positioning pin 34; a fastening screw is arranged in a threaded fit on the fitting surface of the limiting block 35 and the positioning block 31. The fastening screw is slidably arranged in a guide chute. The guide chute is radially opened on the positioning block 31 along the hinge positioning pin 34. The limiting block 35 is fixedly connected to the positioning block 31 through the fastening screw. By sliding and adjusting the distance between the limiting block and the hinge positioning pin, the positioning and installation of hinge structures of various sizes and specifications can be satisfied.

[0020] The main body positioning module 2 is provided with a cushion block 21. The cushion block 21 is in contact with the end face of the opening side of the cabinet body, and a main body positioning pin 22 is arranged on the fitting surface. The main body positioning pin 22 is inserted and matched with the positioning hole on the cabinet body.

[0021] Preferably, magnetic absorption blocks can be embedded on the hinge fitting surface, the cabinet body fitting surface, and the fitting surface of the cushion block. When positioning and installing the hinge, first, the hinge is correspondingly sleeved with the hinge positioning pin, and is in contact with and adsorbed to the hinge fitting surface. Then, the attitude of the hinge is adjusted by using the limiting block. After installing the hinges on multiple hinge positioning modules according to this step, by correspondingly inserting the main body positioning pin into the positioning hole on the cabinet body, the cushion block and the positioning block are both in contact with and firmly adsorbed to the opening end face of the cabinet body. At this time, the hinge is also just in contact with the welding surface, and then the welding operation can be carried out. Among them, in the welding of a multi-door cabinet body, the installation hole of the cabinet door lock body can be selected as the positioning hole inserted and matched with the main body positioning pin, and the relative positions of the hinge positioning module and the main body positioning module in the positioning assembly 5 can be set according to the positions of the hinges and the lock tongues on the cabinet door to ensure the accuracy of the hinge welding position.

[0022] The distance between two adjacent positioning components 5 is adjustable, which can meet the requirements of positioning and welding the hinge positions of cabinet doors with different width sizes on the same cabinet. Specifically, the main frame can be set according to the size of the end face of the cabinet opening side, and then two parallel slide rails are arranged on the side of the main frame close to the cabinet. A cross beam is slidably fitted in the slide rails, and the hinge positioning module and the main body positioning module are respectively fixedly installed at both ends of the cross beam. When the cross beam slides along the slide rail to the specified position, the position can be fixed by fastening screws.

[0023] Preferably, fixed positioning rods are arranged at the four corners of the main frame and are correspondingly inserted into the positioning holes at the four corners of the end face of the cabinet opening side, so that the main frame is completely aligned with the end face of the cabinet opening side. Then, slide and adjust each positioning component 5 so that the main body positioning module is aligned with the corresponding positioning hole and then locked, making the hinge welding tooling more versatile.

[0024] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
