[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] As attached Figure 1 With attached Fig.13 A welding machine for furniture cabinet processing is shown, including a welding machine 1 main device, and a bracket 2 placed in front of the welding machine 1 for supporting and fixing the welded parts. The welding machine 1 as a whole includes an upper welding arm 101 fixed to the machine body, and a lower welding arm 104 that can move up and down. The lower welding arm 104 is assembled with the machine body by sliding up and down through a slide rail, and a cylinder 105 is used as a driving force at the bottom of the lower welding arm 104 to drive the lower welding arm 104 to move up and down.

[0035] like Figures 1 to 3 As shown, a plurality of upper welding heads 102 and lower welding heads 103 corresponding to each other are installed at the ends of the upper welding arm 101 and the lower welding arm 104, and each of the plurality of upper welding heads 102 is driven by an independent cylinder to move up and down.

[0036] According to the welding parts such as furniture cabinet frames, metal mesh partitions, cabinet doors, etc., the cylinder 105 drives the lower welding arm 104 to a suitable position, and the welding parts placed by the bracket 2 are directly pressed by the upper welding head 102 and the lower welding head 103, and the upper welding head 102 on the upper welding arm 101 moves downward to complete the welding. In the present invention, the welding technical scheme of the welding machine 1 is not used as an improved technical scheme of the present invention.

[0037] A support 2 is provided in the welding area at the front of the welding machine 1, and a horizontal frame 201 and a placement frame 3 are arranged on the top of the support 2 in sequence. The horizontal frame 201 is located on the top of the support 2 and moves forward and backward, and the placement frame 3 is located on the top of the horizontal frame 201 and moves left and right.

[0038] The movement of the horizontal frame 201 and the placement rack 3 is mainly achieved by setting a slide rail 306 on the top of the bracket 2 and the horizontal frame 201, and setting a slider 305 adapted to the slide rail 306 at the bottom of the horizontal frame 201 and the placement rack 3, so as to realize the front, back, left and right movement of the horizontal frame 201 and the placement rack 3.

[0039] During welding, the cabinet welded parts are placed on the placement rack 3, and the area to be welded is moved between the welding heads to complete the welding.

[0040] like Figures 4 to 8 As shown, in order to ensure that the cabinet welding area can be accurate, the placement rack 3 and the horizontal frame 201 will be equipped with a locking and positioning mechanism after moving in the existing equipment. Compared with the existing equipment, the locking mechanism of the placement rack 3 and the horizontal frame 201 in the present invention can move synchronously with the placement rack 3, so it is more convenient during use.

[0041] Specifically, a joystick 5 is provided on one side of the placement rack 3, through which the placement rack 3 and the horizontal frame 201 can be moved, and handles 7 are installed on the sides of both ends of the joystick 5, and a pull rod 701 is slidably installed on the inner wall of the rectangular handle 7 through a sliding groove, that is, the staff holds the joystick 5 in their hands, and the fingers can hold the pull rod 701 to pull it.

[0042] like Figure 8 , Fig.11 As shown, the locking mechanism for the placement rack 3 after the horizontal frame 201 moves is that a lock piece 26 is provided on one side of the bottom of the placement rack 3, and two assembly columns 205 are fixedly provided on the top of the lock piece 26. The assembly columns 205 are movably inserted into the bottom of the placement rack 3, that is, the lock piece 26 can move up and down on the placement rack 3 through the assembly columns 205, and a spring 204 is sleeved on the assembly columns 205.

[0043] The bottom of the lock 2 6 is provided with an arc-shaped through groove that fits the slide rail 306, and the lock 2 6 is made of rubber material.

[0053] During assembly, the L-shaped locking rod 8 can be moved arbitrarily along the length direction on the bracket 2 and the placement rack 3, and the placement rack 3 can be fixed at any position of the horizontal frame 201 by rotating the embossed knob 803 as needed.

[0054] A locking wrench 804 is also provided on the top of the L-shaped locking rod 8, and a threaded column (not shown in the figure) is provided at the bottom of the locking wrench 804. The threaded column passes through the L-shaped locking rod 8 and extends to the surface of the telescopic rod 802 to lock the telescopic rod 802 for movement.

[0055] By controlling the telescopic length of the telescopic rod 802 through the locking wrench 804 , the horizontal frame 201 and the placement frame 3 can be controlled to move forward and backward on the bracket 2 .

[0056] Two groups of L-shaped locking rods 8 are provided, which are suitable for welding cabinets with larger volumes. Before welding, the placement rack 3 is fixed in the welding area by the L-shaped locking rods 8 , and the cabinet is placed on the placement rack 3 .

[0057] The two L-shaped locking rods 8 can also be locked by the embossed knob 803 located above the bracket 2. In this state, the placement rack 3 can only move forward and backward, or the telescopic rod 802 can be fixed by locking the wrench 804. In this state, the placement rack 3 can only move left and right.
