Description

Technical Field

[0001] The utility model relates to the field of processing of hand mold base brackets, and particularly relates to a welding positioning device for hand mold base brackets. Background Technique

[0002] A hand mold base bracket is a device used to support and fix a hand mold. When it is processed, the chassis and the boss on it are generally welded to connect the two into one body.

[0003] During welding processing, the positioning device in the prior art uses two positioning discs or seats to position two workpieces, and presses the two workpieces tightly against each other.

In the above way, in order to enable the two workpieces to rotate together, the pressing force between the workpieces needs to be maintained at a relatively large value to increase the frictional force. When the pressing force between the workpieces is relatively large, workpieces with insufficient rigidity or thin thickness may be damaged by pressing. Summary of the Utility Model

[0054] The first positioning groove 701 and the second positioning groove 702 on the two carrier plates 7 are respectively used for placing two tools to be welded, and the shapes of the first positioning groove 701 and the second positioning groove 702 are adapted to the shape of the workpiece a to be welded.

[0055] As Figure 1 shown, the translation mechanism 2 includes a guide block 201, a first motor 202, a nut 203 and a screw rod 204; the screw rod 204 is rotatably installed in the base 1, and the screw rod 204 is threadedly connected with the nut 203. The top surface of the nut 203 is fixedly connected with the guide block 201, the guide block 201 is slidably connected with a guide groove 101 opened on the base 1, and the guide block 201 is fixedly connected with the bottom end of the first support rod 3. The output shaft end of the first motor 202 is fixedly connected with one end of the screw rod 204, and the first motor 202 is fixedly installed on the side wall of the base 1.

[0056] The first motor 202 drives the screw rod 204 to rotate, the screw rod 204 and the nut 203 are screwed, and with the guiding action provided by the guide block 201 and the guide groove 101, the nut 203 and the guide block 201 move horizontally together, and the first side cover 5 and the carrier plate 7 on the first side cover 5 are driven to move together through the first support rod 3, so that the carrier plate 7 on the first side cover 5 approaches or moves away from the carrier plate 7 on the second side cover 6.

[0057] As Figures 1-2As shown, the rotation drive mechanism 10 is connected to a second motor 9, and the second motor 9 is fixedly installed on the outer wall of the second side cover 6; the rotation drive mechanism 10 includes a first gear 1001, a rotating shaft 1002, and a second gear 1003; a portion of the carrier plate 7 extending into the second side cover 6 is fixedly sleeved with the second gear 1003, and the second gear 1003 is coaxially arranged with the carrier plate 7.

The rotating shaft 1002 is rotatably installed in the second side cover 6, and one end of the rotating shaft 1002 is fixedly connected to the output shaft end of the second motor 9.

[0058] When the second motor 9 drives the rotating shaft 1002 to rotate, through the meshing transmission between the first gear 1001 and the second gear 1003, the carrier plate 7 on the second side cover 6 rotates.

[0059] As Figure 4 shown, the docking mechanism includes a straight rod 8 arranged horizontally, a plug post 11, and a slot 12. The number of the straight rods 8 is two, and the two straight rods 8 are respectively connected to the two carrier plates 7. A plug post 11 is fixedly connected to the end of the straight rod 8 on the left side of the top of the base 1, and a slot 12 for the plug post 11 to insert is provided at the end of the straight rod 8 on the right side of the top of the base 1.

[0060] During the process of moving the left carrier plate 7 closer to the right carrier plate 7, the two straight rods 8 are aligned with each other. When they are not aligned, the carrier plate 7 on the first side cover 5 can be manually rotated to align the straight rods 8; during the above process, until the carrier plate 7 moves to the state as Figure 4 shown, the plug post 11 is inserted into the slot 12 to complete the docking.

[0061] The two carrier plates 7 can rotate together, so that the workpieces a clamped and limited therein rotate together, and all positions in the circumferential direction are moved to the top, which is convenient for welding at all positions in the circumferential direction at the top; there is a distance between the position where the straight rod 8 is in contact with the two workpieces a, and the end of the welding torch can be inserted, and the straight rod 8 will not block the welding.

[0062] As Figure 4As shown, an inner cavity 14 is formed in the carrier plate 7, and the pressing mechanism 13 is arranged in the inner cavity 14. The pressing mechanism 13 includes a connecting rod 1301, a first spring 1302 and a contact block 1303. The first spring 1302 is arranged along the radial direction of the carrier plate 7. The connecting rod 1301 is elastically connected to the wall of the inner cavity 14 through the first spring 1302. One end of the connecting rod 1301 is fixedly connected to the pressing column 16, and the other end of the connecting rod 1301 is fixedly connected to the contact block 1303. Each of the two carrier plates 7 is provided with a first guide hole 15 along the radial direction, and the two first guide holes 15 are respectively communicated with the first positioning groove 701 and the second positioning groove 702. The pressing column 16 is in clearance fit with the first guide hole 15. A rubber gasket is fixedly connected to the end of the pressing column 16. The carrier plate 7 is provided with a second guide hole 17 along the transverse direction. The straight rod 8 is in clearance fit with the second guide hole 17. One end of the straight rod 8 extends into the inner cavity 14, and a stop block 1306 is fixedly connected to the end of the straight rod 8 located in the inner cavity 14. The stop block 1306 abuts against the bottom of the contact block 1303. One side wall of the stop block 1306 is elastically connected to the side wall of the inner cavity 14 through a second spring 1305, and a stop post 1304 aligned with the stop block 1306 is fixedly connected to the side wall of the inner cavity 14.

[0063] It should be noted that in the state as shown in Figure 4 and the state where the two carrier plates 7 are far away from each other, both the first spring 1302 and the second spring 1305 are in a compressed state, and the contact block 1303 is in contact with the stop block 1306, and the two cancel each other out. The pressing column 16 does not press on the workpiece a, and the pressing column 16 does not extend into the first positioning groove 701 and the second positioning groove 702, so it will not affect the placement of the workpiece a.

[0064] After the two carrier plates 7 are docked, in the state as shown in Figure 4 and during the process of continuously moving the two carrier plates 7 closer to each other until the two workpieces a are in contact, the two straight rods 8 are pressed against each other, increasing the compression amount of the second spring 1305, causing the straight rod 8 and the stop block 1306 to move together. The stop block 1306 is in contact with the stop post 1304, and the stop block 1306 is separated from the extrusion block. The extrusion block loses the block, and the elastic force of the first spring 1302 acts on the pressing column 16 through the connecting rod 1301, so that the pressing column 16 presses the workpiece a in the first positioning groove 701 and the second positioning groove 702, providing automatic pressing and limiting before welding processing.

[0065] After the welding process, the carrier plates 7 are separated, and the straight rod 8 loses the mutual pressure. Through the elastic force of the second spring 1305, the straight rod 8 and the pressing block are reset, and the pressing block returns to the bottom of the extrusion block again, so that the pressing column 16 automatically cancels the pressing limit.

[0066] The surfaces of the stop block 1306 and the contact block 1303 in contact with each other adopt an inclined surface structure.

[0067] The present utility model is not limited to the above-mentioned embodiments. No matter what changes are made in its shape or structure, they all fall within the protection scope of the present utility model. The protection scope of the present utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the present utility model, but these changes and modifications all fall within the protection scope of the present utility model.
