Description

Technical Field

[0001] The utility model relates to the field of welding fixtures used in the production of power distribution cabinets, and more specifically, to a welding fixture used in the production of power distribution cabinets. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load;

[0003] When assembling and welding the power distribution cabinet, there are four steel plates in total, which form a rectangular structure. Welding is required at the joints of adjacent steel plates. Currently, there is no targeted clamp on the market for fixing the steel plates. After welding, diagonal deviation is prone to occur, resulting in low manufacturing accuracy of the power distribution cabinet. In order to solve the above problems, a special clamp for welding the power distribution cabinet is proposed;

[0004] In the prior art, patent authorization announcement number CN212239814U discloses a special fixture for welding distribution cabinets, wherein a square notch is provided at each of the four top corners of the welding table, and a center block is vertically fixed to the center of the end face of the welding table, and the upper sides of the inner, outer, left and right end faces of the center block are connected to a limit plate 1 through a telescopic rod, and a screw rod is fixed to the middle of the end face of the limit plate 1 facing the center block, and a sleeve is rotatably installed through a support bearing at the positions of the inner, outer, left and right end faces of the center block corresponding to the screw rod, and an internal thread matching the external thread of the screw rod is provided on the inner wall of the sleeve, and the other end of the screw rod not connected to the limit plate 1 extends into the sleeve on the same side and is threadedly connected to the sleeve, and the piston rod of the cylinder extends to one side of the center block through the vertical plate, and the end of the piston rod of each cylinder is fixed to a limit plate 2, and a layer of rubber pad is bonded to the end face of the limit plate 1 on the opposite side of the limit plate 2. The utility model can ensure the stability of the steel plate during welding and improve the manufacturing accuracy of the distribution cabinet;

[0005] In the above-mentioned patent, independent internal and external structures are used to clamp the plates for welding. During welding, different plates need to be adjusted to fix their positions, and their extrusion points need to be adjusted. Due to the use of independent internal and external clamping structures, the adjustment is not convenient. The inner end is squeezed outward and the outer end is squeezed inward. Two sets of clamping mechanisms need to be adjusted during adjustment, which is inconvenient to coordinate, complicated to operate, complicated in structure, and high in cost. Utility Model Content

By adopting a support plate body with adjustable threads distributed all around, the support position can be moved, and a movable clamping plate is arranged outside the support plate body. The plate can be added to the support plate body first, and then the position of the support plate body can be adjusted to squeeze together. It is easy to adjust, and only the position of the outer end support plate body needs to be adjusted. The structure is simple and the cost is low.

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] The cam is provided with a plurality of grooves on the upper and lower surfaces of the welding fixture base, and a plurality of grooves are provided on the upper and lower surfaces of the welding fixture base to form a plurality of grooves.

[0009] Furthermore, a supporting rotating convex seat is fixed to the inner surface of the outer end of the positioning sliding groove of the welding fixture base, and the outer surface of the threaded rod is connected to the inner surface of the positioning sliding groove through a supporting bearing.

[0010] Furthermore, a twist handle is fixedly connected to the outer end surface of the threaded rod, and the twist handle is welded and fixed to the outer end surface of the threaded rod.

[0011] Furthermore, the positioning sliding grooves adopt a square groove structure, and the positioning sliding grooves are distributed on the upper, lower, left and right end surfaces of the welding fixture base and are symmetrically distributed.

[0012] Furthermore, a threaded opening is provided on the outer surface of the supporting plate body, and the threaded opening is connected to the outer surface of the threaded rod through threads.

[0013] Furthermore, the welding fixture base adopts a square seat structure, and the depth of its positioning sliding groove is not less than ten centimeters.

[0014] Furthermore, the width of the supporting plate body and the movable clamping plate member is not less than thirty centimeters.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) By adopting a support plate body with adjustable threads distributed all around, the support position can be moved, and a movable clamping plate is arranged outside the support plate body. The plate can be added to the support plate body first, and then the position of the support plate body can be adjusted to squeeze them together. It is easy to adjust, and only the position of the outer end support plate body needs to be adjusted. The structure is simple and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS
