Description

Technical Field

[0001] The utility model relates to the field of electric turntable preparation, in particular to a welding tool for an upper bracket of an electric turntable. Background Art

[0002] In paper mills and logistics conveyor lines, a turntable that can change the direction of the conveyed object is needed when transporting materials. Because the positioning space limits its size, when the length of the conveyed object is greater than the rotation diameter of the conveyor line, if the conveyed object is directly rotated, it will interfere with the conveying equipment connected to the front and rear. Therefore, there is an electric turntable (such as the electric turntable for paper roll conveying disclosed in the prior art CN202220164591.6); the bottom of the electric turntable is composed of a plurality of support frames and arc-shaped support plates (such as Figure 1 As shown in the figure), during the production of the electric turntable, the upper surface of the bracket needs to be kept on the same horizontal plane to facilitate the welding of the turntable, so the bracket requires higher welding accuracy.

[0003] The existing welding is only done by manual positioning, and during welding, it is also done one by one by manually positioning with one hand and welding with the other hand. This purely manual marking and manual positioning method is not only prone to errors during marking, but also prone to errors during welding due to human factors (such as the inevitable shaking of the human body), making it difficult to ensure welding accuracy. In addition, in order to ensure quality, re-welding is usually required due to errors. Repeated welding damages the arc support sheet and the support frame, and wastes manpower and material resources; furthermore, since the structure of the arc support sheet is prone to shaking and deformation, it is extremely difficult to weld, and deformation and cracks in the weld are prone to occur during welding. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a welding tool for the upper bracket of an electric turntable, which uses an annular positioning groove and a positioning block to accurately position the support frame and the arc-shaped support plate that need to be welded on the electric turntable, so as to ensure the welding accuracy and improve work efficiency.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] Provided is a welding tool for an upper bracket of an electric turntable, comprising: a base, an annular positioning groove, a positioning block and a positioning screw;

[0007] The base is circular, and an annular positioning groove for installing an arc-shaped support plate is provided on its upper surface. The annular positioning grooves are arranged in sequence from the inside to the outside around the center of the base, and the bottoms of the annular positioning grooves are located on the same plane. Positioning blocks for installing the support frame are symmetrically provided on both sides of the symmetry axis of the base, and the positioning blocks are provided with positioning holes. The positioning holes fix the support frame by cooperating with the positioning screws.

[0008] It should be noted that, by means of the annular positioning groove provided on the base, the arc-shaped support piece can be inserted into the annular positioning groove for fixation, which not only plays a positioning role so that the lower end of the arc-shaped support piece is on the same horizontal plane, but also can effectively prevent the arc-shaped support piece from deforming in the radial direction, so that it can always maintain a fixed curvature; each support frame is also fixed by the cooperation of the positioning block and the positioning screw, which can effectively prevent the support frame from moving during the welding process, and the positioning screw can also adjust the horizontality of the support frame so that the side of the support frame connected to the turntable can remain horizontal, ensuring precise welding with the annular support piece and ensuring product quality.

[0009] Preferably, the positioning screw includes a locking screw and a jacking screw, the locking screw is used to fix the support frame, the jacking screw can lift one end of the support frame fixed on the positioning block, and cooperate with the locking screw to adjust the horizontality of the support frame.

[0010] It should be noted that the locking screw is used to fix the support frame to ensure that the support frame will not loosen or shift during the welding process, thereby improving the accuracy and stability of welding; and the tightening screw can fine-tune the support frame to achieve the optimal horizontal state. When used in conjunction with the locking screw, the support frame can be quickly adjusted and fixed, thereby improving work efficiency.

[0011] Preferably, the positioning block includes a horizontal plate, a vertical plate and a reinforcing plate, one end of the horizontal plate is welded to the end of the vertical plate and is perpendicular to each other, and is fixed to the base through the horizontal plate, the reinforcing plate is welded at the vertical angle of the horizontal plate and the vertical plate, and the positioning hole is set on the vertical plate.

[0012] It should be noted that the horizontal plate, as the basic part of the positioning block, ensures the stability of the positioning block and provides support for the vertical plate; the design of the vertical plate enables the positioning hole to be accurately aligned with the support frame, thereby improving the positioning accuracy. The presence of the reinforcing plate increases the bending and torsion resistance of the positioning block, thereby improving the durability and service life of the positioning block.

[0013] Preferably, a cushion block is provided at the position where the vertical plate is connected to the support frame.

[0014] It should be noted that the pad can reduce the friction and wear between the support frame and the positioning block, thereby extending the service life of the tooling.

[0015] Preferably, a plurality of groups of screw holes are provided at intervals on both sides of the symmetry axis of the base, and the positioning block is fixed to the base by the cooperation of bolts and the screw holes.

[0016] It should be noted that the positioning block is fixed with different screw holes, and the position of the positioning block can be adjusted as needed to adapt to the fixation of support frames of different specifications and shapes.

[0017] Preferably, the base is composed of two semicircular platform plates.

[0018] It should be noted that when the tooling is not in use, the two semicircular tabletops can be nested or stacked on each other, reducing the occupied space and facilitating storage and transportation.

[0019] Preferably, a reinforcement frame is welded to the lower surface of the base.

[0020] It should be noted that the reinforcement frame can increase the bearing capacity and stability of the base, so that it can withstand a larger load without deformation or damage, and further ensure the welding accuracy of the arc-shaped support sheet.

[0021] Beneficial effects of the utility model:

[0022] The utility model provides a welding tool for an electric turntable upper bracket, which ensures the overall stability of the tool and the accurate positioning of the arc-shaped support piece through the design of the base, the annular positioning groove and the positioning block, thereby improving the accuracy and quality of welding; in particular, the cooperation of the locking screw and the tightening screw allows the horizontality of the support frame to be quickly adjusted and fixed, thereby improving work efficiency, and also enhances the structural strength and wear resistance of the tool by arranging components such as reinforcing plates, pads and reinforcing frames, thereby extending the service life of the tool.
