In the processing process, errors occur in the positions of the positioning holes in the sheet metal part, so that the positioning pins cannot be inserted into the positioning holes in the sheet metal part and cannot be firmly positioned, and therefore, when the positioning pins 11 are used, the diameter of the conical movable end of the positioning pin core body 113 is gradually increased from zero, and the conical movable end of the positioning pins 11 can be firstly inserted into the positioning holes in the sheet metal part; if the tip of the tapered movable end of the positioning pin core body 113 is not in the middle of the positioning hole and the positioning pin 11 cannot float, under the thrust of the driving mechanism 4, although the positioning pin can be inserted into the positioning hole of the sheet metal part, the appearance of the sheet metal part is easy to damage, therefore, by using the positioning pin of the embodiment, the situation can be avoided, and the specific principle is as follows: the positioning pin core body 113 is inserted into the sheet metal part positioning hole, and due to errors, the middle position of the sheet metal part positioning hole is not inserted, along with the pushing of the driving mechanism, the positioning pin core body 113 overcomes the elastic force of the spring 114 to gradually deviate, so that the positioning pin core body 11 is smoothly inserted into the sheet metal part positioning hole, the peripheral part of the sheet metal part positioning hole is abutted against the tapered sliding block 115, the tapered sliding block 115 overcomes the elastic force of the spring 114 to move towards the cavity, and finally the tapered sliding block 115 is abutted against the inner wall at the opening of the cavity, so that the positioning pin core body 113 does not float any more, at the moment, the positioning pin 11 is inserted into the sheet metal part positioning hole to realize positioning, and at the moment, the moving block 31 is abutted against the corresponding limiting block 33, so that the driving mechanism 4 is maintained in the state, the integral positioning of the sheet metal part is realized, and the appearance structure of the sheet metal part is not damaged.
When the positioning pin units 1 need to move, the driving mechanism 4 pushes the movable workbench 5 to move along the linear slide rail 2, so that the movable workbench and the fixed workbench 6 generate relative displacement, and the synchronous movement of the positioning pin units 1 is realized; meanwhile, two sets of limiting mechanisms 3 are further mounted on the fixed workbench 6 and the movable workbench 5, in any one set of limiting mechanism 3, the moving block 31 is welded on the side face of the movable workbench 5, two limiting blocks 33 are mounted on the fixed workbench 6 in the front-back direction in which each moving block 31 moves, when the rubber cushion block 32 on one side of each moving block 31 is in contact with the corresponding limiting block 33, the position induction sensor 36 sends out a position signal to stop the driving mechanism 4 and keep the working position, the distance between the two limiting blocks 33 is smaller than or equal to the stroke of the cylinder, and the limiting blocks 33 and the driving mechanism 4 fix the position of the movable workbench 5, so that accurate positioning of the positioning pin 11 is realized.
When the positioning pin unit 1 is required to position the sheet metal part, the driving mechanism 4 pushes the movable workbench 5 to drive the positioning pin unit 1 to be inserted into the corresponding sheet metal part positioning hole, meanwhile, the movable block 31 abuts against the corresponding limiting block 33, and the position sensing sensor 36 sends a position signal at the moment, so that the driving mechanism stops and maintains the working position at the moment, and the sheet metal part is ensured to be positioned; when the sheet metal part is welded and the positioning pin unit 1 needs to be reset, the driving mechanism 4 pulls the movable workbench 5 to enable the positioning pin unit to be away from the sheet metal part, the movable block 31 abuts against the other limiting block 33, and meanwhile, the position sensing sensor 36 sends out a position signal to enable the driving mechanism 4 to stop and maintain the working position at the moment.
The working process is as follows:
the initial position of the movable workbench 5 is located at the position when the cylinder is in a retraction state, the movable block 31 on the movable workbench 5 is in contact with the limit block 33 close to one side of the cylinder, and at the moment, the position sensing sensor 36 at the corresponding position sends out a position signal, so that the driving mechanism does not act any more and maintains the position at the moment; after the sheet metal component welding was accomplished, the push rod shrink of cylinder will remove the workstation and draw 5 back to initial position, and the locating pin also withdraws from the automobile body sheet metal component locating hole to the good automobile body sheet metal component of welding is conveniently taken off.
