Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1 to 5, a welding jig for an upper cover of a motor casing according to the present invention includes: base 1, positioning mechanism and clamping mechanism.
Specifically, the positioning mechanism is provided with a middle positioning piece 2 and at least two outer positioning columns 3 arranged in the circumferential direction of the middle positioning piece 2, a first supporting block 4 and a second supporting block 5 which are placed below a welding position are arranged on the middle positioning piece 2, the first supporting block 4 and the second supporting block 5 are arranged adjacently, the section of the upper end of the first supporting block 4 is arc-shaped, and the middle position of the first supporting block 4 is higher than the positions of two sides of the first supporting block 4; the clamping mechanism is arranged on the base 1 and located in the circumferential direction of the middle positioning part 2, a plurality of first clamping pieces 6 and second clamping pieces 7 are arranged on the clamping mechanism at intervals, the first clamping pieces 6 are used for clamping the welding positions of two workpieces, the second clamping pieces 7 are used for clamping the edges of the workpieces, the number of the first clamping pieces 6 and the number of the second clamping pieces 7 are determined according to the size of the shell 15, and generally, the larger the shell is, the more the number of the first clamping pieces 6 and the number of the second clamping pieces 7 are.
When the device works, the shell 15 and the welding part 16 are placed on the positioning mechanism, the outer positioning column 3 is inserted into the mounting hole of the shell 15, the outer positioning column 3 can support the shell 15 and prevent the shell 15 from being placed wrongly, the welding part 16 is placed on the middle positioning part 2, after the shell 15 and the welding part 16 are placed, the second clamping part 7 on the clamping mechanism is clamped at the edge of the shell to prevent the shell from moving under the action of the action force exerted on the welding tool during welding, the first clamping part 6 is clamped at the position where the shell 15 is adjacent to the welding part 16 and can further reinforce the shell 15 and the welding part 16, the first supporting block 4 and the second supporting block 5 arranged on the middle positioning part 2 abut against the bottom of the welding position, and the welding path of the workpiece in the length direction of the first supporting block 4 is long, the welding part 16 is easy to deform downwards at the middle position of the first supporting block 4 under the action of a welding tool during welding, so that the section of the upper end of the first supporting block 4 is set to be a circular arc surface with a high middle and two low sides, and the highest point of the circular arc can play an additional supporting role on the welding part 16 and the shell 15 during welding, so that the shell 15 and the welding part 16 are prevented from deforming at the position.
As shown in fig. 1 and 3, each of the first clamping member 6 and the second clamping member 7 includes an oil cylinder 8, a fixing block 9 and a pressing block 10, the fixing block 9 is disposed at the upper end of the oil cylinder 8, one end of the pressing block 10 is hinged to the output end of the oil cylinder 8, and the middle position of the pressing block 10 is hinged to the upper end of the fixing block 9. When the clamping device works, the oil cylinder 8 drives one end, far away from a workpiece, of the pressing block 10 to rotate around the upper end of the fixing block 9, and when the pressing block 10 rotates, the other end of the pressing block is attached to or separated from the upper surface of a welding position, so that the first clamping piece 6 and the second clamping piece 7 are clamped on the welding position and are separated from the welding position.
The clamping mechanism further comprises abutting columns 11 with the same number as the second clamping pieces 7, the abutting columns 11 are arranged on the sides of the second clamping pieces 7, when the second clamping pieces 7 are attached to the upper surface of the shell 15, the abutting columns 11 abut against the lower end face of the shell 15, and the abutting columns 11 are matched with the second clamping pieces 7 to fix the shell 15.
As shown in fig. 3, each first clamping member 6 is screwed with an abutting block 12, and the abutting block 12 can be more conveniently dismounted by adopting a screwing installation mode.
When the welding tool performs welding operation, a large amount of heat is generated at a welding position, the workpiece can be moved after the workpiece is sufficiently cooled after welding is completed, otherwise, the shell 15 and the welding part 16 are welded insufficiently and firmly.
As shown in fig. 1 and 2, at least two hanging rings 14 are arranged on the base 1, and the hanging rings 14 can facilitate the movement of the welding jig.
