DETAILED DESCRIPTION

[0022] The following specific embodiments illustrate the implementation of the present invention, and those familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] See also Figure 1-2 The utility model provides a fixing fixture for a polygonal workpiece, including a workbench 100, on which a plurality of positioning components 200 are arranged in a circular array. Each side of the polygonal workpiece 400 is clamped and fixed by each positioning component 200, so as to ensure that the polygonal workpiece 400 is firmly fixed and not easy to shake.

[0024] refer to Figure 3 The positioning assembly 200 includes a guide rail 210, a slide 220 and a driving member 230. The slide 220 is slidably connected to the guide rail 210. The output end of the driving member 230 is connected to the slide 220 for driving the slide 220 to slide along the guide rail 210. A first clamp 221 and a second clamp 222 are provided on the slide 220. The first clamp 221 clamps the polygonal workpiece 400 along the width direction of the side thereof, and the second clamp 222 clamps the polygonal workpiece 400 along the height direction thereof.

[0025] On the one hand, each positioning assembly 200 includes a first clamp 221 and a second clamp 222, which can simultaneously clamp the side edges of the polygonal workpiece 400 from the lateral and longitudinal directions to ensure that the side edges are firmly fixed and will not loosen or shake; on the other hand, the first clamp 221 and the second clamp 222 are arranged on the slide 220, and their distance from the side edges can be adjusted along the guide rail 210, so that the fixing clamp is suitable for polygonal workpieces 400 of different sizes.

[0026] Furthermore, the slide 220 is provided with a stopper 223 in the same direction as the corresponding side of the polygonal workpiece 400, the first clamp 221 is arranged on the outside of the stopper 223, and the second clamp 222 is arranged above the stopper 223. The position of the slide 220 can be determined by the stopper 223, and the inner side of the polygonal workpiece 400 can be preliminarily positioned by the stopper 223, and then the first clamp 221 clamps it from the outside. The first clamp 221 is a push-pull type quick clamp, and the second clamp 222 is an upper and lower type quick clamp.

[0027] refer to Figure 4The guide rail 210 is provided with an inverted "T"-shaped slide groove 211 along its length direction, and the bottom of the slide 220 is provided with an inverted "T"-shaped slide bar 224 matching the inverted "T"-shaped slide groove 211. The inverted "T"-shaped slide groove 211 and the inverted "T"-shaped slide bar 224 can ensure the running stability of the slide 220 and prevent it from tilting to both sides.

[0028] refer to Figure 1-3 The driving member 230 is fixed on the guide rail 210, and the driving member 230 is a cylinder, an oil cylinder or a motor.

[0029] Furthermore, the driving member 230 is preferably a synchronous cylinder, so that the upper slide 220 of each positioning assembly 200 slides synchronously and cooperates with the regular polygonal workpiece 400.

[0030] Furthermore, the number of the positioning components 200 is consistent with the number of sides of the polygonal workpiece 400, and the placement direction of the positioning components 200 is perpendicular to the corresponding sides of the polygon, thereby ensuring that each side of the polygonal workpiece 400 is clamped and the polygonal workpiece 400 is firmly fixed.

[0031] In one embodiment of the present invention, reference is made to Figure 1-2 The workbench 100 is placed on the bracket 300, and connecting seats 110 are provided on both sides of the workbench 100. The connecting seats 110 and the bracket 300 are rotatably connected. By rotating the workbench 100 and the bracket 300, the position of the polygonal workpiece 400 can be adjusted 360 degrees, which is more convenient for welding the workpiece.

[0032] Furthermore, the workbench 100 is disc-shaped.

[0033] Furthermore, the polygonal workpiece 400 is a regular octagonal frame structure or a regular hexagonal frame structure, etc.

[0034] When in use, a corresponding number of positioning components are installed on the workbench according to the number of sides and shape of the polygonal workpiece, and then the position of the slide on the positioning component is adjusted so that the polygonal workpiece is placed on the stop block, and then the first clamp and the second clamp clamp the polygonal workpiece from two directions.

[0035] In summary, the utility model sets a plurality of positioning components to clamp and fix each side of the polygonal workpiece, ensuring that the polygonal workpiece is firmly fixed and not easy to shake; and the first clamp and the second clamp can clamp the side of the polygonal workpiece synchronously from the lateral and longitudinal directions, effectively preventing each side of the polygonal workpiece from displacement; at the same time, a slide and a guide rail are set, so that the fixing clamp is suitable for polygonal workpieces of different sizes.
