Description

Technical Field

[0001] The utility model relates to the technical field of zinc-magnesium-aluminum square tube tapping, in particular to a zinc-aluminum-magnesium square tube tapping screw clamping and fixing tool. Background Art

[0002] As the name suggests, zinc-magnesium-aluminum square tubes are square tubes that combine zinc, magnesium, and aluminum. These square tubes are fused together through a specific process, creating a metal material with unique properties. In a comparative case study, publication number CN213969374U discloses a tapping device that facilitates clamping and fixing, comprising a tapping machine body, a T-shaped chute defined at the upper end of the workbench of the tapping machine body, a first fixing plate fixedly connected to the upper end of the workbench, and a first T-shaped slider and a second T-shaped slider slidably connected to the interior of the T-shaped chute from left to right. The tapping device which is convenient for clamping and fixing has the advantages of being convenient for fixing the workpiece and having a good fixing effect, and solves the problem that most existing tapping machines use a clamping device similar to a bench vise, and when in use, the staff needs to manually turn the handle to adjust the clamping force. When the clamping force is insufficient, the workpiece is easy to loosen, and when the clamping force is too large, the workpiece is easy to be crushed, which places certain technical requirements on the staff. In the process of long-term continuous work, the clamping force is difficult to control. Therefore, a tapping device which is convenient for clamping and fixing is proposed to solve the above-mentioned problems.

[0003] However, in the implementation of relevant technologies, it was found that the above-mentioned tapping device for convenient clamping and fixing had the following problems. In the comparative case, the workpiece is clamped and fixed by using a tapping machine body, a T-shaped slide groove, a first fixed plate, a first T-shaped slider and a second T-shaped slider. The structure is complex and occupies mechanical space. The workpiece cannot be positioned during processing by the existing tapping machine, resulting in displacement of the workpiece during tapping, which makes the machine unable to process normally and reduces the efficiency of the tapping machine processing.

[0004] Therefore, it is necessary to redesign the tapping machine to effectively prevent the problem that the workpiece cannot be positioned during tapping, resulting in displacement of the workpiece during tapping and the machine cannot process normally. Utility Model Content

[0023] like Figures 1 to 4 As shown, the utility model provides a zinc-aluminum-magnesium square tube tapping screw clamping and fixing tool, comprising:

[0024] Tapping machine 1;

[0025] The front end of the tapping machine 1 is fixedly connected to a processing table 2, the bottom of the processing table 2 is fixedly connected to a connection box 3, and the left and right sides of the bottom of the inner wall of the connection box 3 are fixedly connected to positioning mechanisms 4;

[0026] The positioning mechanism 4 includes a rectangular plate 401, an L slide bar 402, a fixed sleeve 403, a horizontal plate 404, a U-shaped holder 405, a movable rod 406, a connecting rod 407, a balancing rod 408, a sliding sleeve 409, a pull rod 410, a fixing ring 411 and an L connecting rod 412. The left and right sides of the bottom of the inner wall of the connecting box 3 are fixedly connected with the rectangular plate 401, the inner side of the rectangular plate 401 is slidingly connected with the L slide bar 402, the end of the L slide bar 402 away from the rectangular plate 401 is fixedly connected with the fixing sleeve 403, the inner cavity of the fixing sleeve 403 is fixedly sleeved with the horizontal plate 404, the front end and the back end of the horizontal plate 404 are both fixedly connected to one side of the fixing sleeve 403, the top of the U-shaped holder 405 is penetrated to the top of the processing table 2, and the front end and the bottom of the horizontal plate 404 are fixedly sleeved with the U-shaped holder 405. The back end is movably connected to a movable rod 406 through a rotating shaft, and the bottom of the left side of the movable rod 406 is movably connected to a connecting rod 407. The front end of the rectangular plate 401 is fixedly connected to a balance rod 408, and the front end of the balance rod 408 is fixedly connected to the other side of the rectangular plate 401. The surface of the balance rod 408 is slidably sleeved with a sliding sleeve 409, and the end of the connecting rod 407 away from the movable rod 406 is fixedly connected to the right side of the sliding sleeve 409. The front end of the connecting box 3 is movably connected to a pull rod 410, and the back end of the pull rod 410 passes through the interior of the connecting box 3. The front end and back end of the surface of the pull rod 410 are fixedly connected to a fixed ring 411, and the bottom of the sliding sleeve 409 is fixedly connected to an L connecting rod 412, and the end of the L connecting rod 412 away from the sliding sleeve 409 is fixedly connected to the left side of the fixed ring 411.

[0027] refer to Figure 3 A sliding groove 5 is provided on the right side of the rectangular plate 401 and corresponds to the position of the L sliding rod 402 , and the sliding groove 5 is used in conjunction with the L sliding rod 402 .

[0028] As a technical optimization solution of the present invention, through the setting of the slide groove 5, the L slide bar 402 can move up and down inside the slide groove 5, and at the same time play a limiting role, avoiding the phenomenon of the L slide bar 402 being offset during the movement.

[0029] refer to Figure 2 The front end and the back end of the balance bar 408 are both sleeved with a tension spring 6, and the front end and the back end of the tension spring 6 are fixedly connected to the front end of the sliding sleeve 409 and the surface of the balance bar 408 respectively.

[0036] As a technical optimization solution of the present invention, the setting of the grip wheel 9 can assist the pull rod 410 in working, and at the same time play the role of hand-held operation, avoiding the phenomenon of the pull rod 410 falling out of the hand during the operation.

[0037] The working principle and use process of the utility model are as follows: when in use, a square tube workpiece is placed on the inner side of the U-shaped holder 405 by hand, and then the grip wheel 9 is manually pulled forward. The grip wheel 9 moves forward to drive the pull rod 410 to move forward. The pull rod 410 moves forward to drive the fixed ring 411 and the L connecting rod 412 to move along. The L connecting rod 412 moves forward to drive the sliding sleeve 409 to move forward stably along the balance rod 408. When the sliding sleeve 409 moves, it cooperates with the tension spring 6 to reset and propel forward. The sliding sleeve 409 moves forward to drive the connecting rod 407 and the bottom end of the movable rod 406 Following the movement, the bottom end of the movable rod 406 moves forward so that the top end rotates around the rotating shaft and pulls the horizontal plate 404 downward to move downward. The horizontal plate 404 moves downward to drive the fixed sleeve 403 and the L slide bar 402 to move synchronously. The L slide bar 402 cooperates with the slide groove 5 to move on the surface of the rectangular plate 401. Finally, the horizontal plate 404 drives the U-shaped holder 405 downward to move downward and clamp it on the surface of the square tube workpiece for fixation, and then the tapping machine 1 is started to perform tapping operation. Similarly, the U-shaped holder 405 is released from the fixation of the square tube workpiece for replacement and repeatable processing.

[0038] To sum up: the zinc-aluminum-magnesium square tube tapping screw clamping and fixing tool, through the tapping machine 1, processing table 2, connecting box 3, positioning mechanism 4, rectangular plate 401, L slide bar 402, fixed sleeve 403 horizontal plate 404, U-shaped holder 405, movable rod 406, connecting rod 407, balance rod 408, sliding sleeve 409, pull rod 410, fixed ring 411 and L connecting rod 412, solves the problem that the workpiece cannot be positioned during the existing tapping machine processing, resulting in displacement of the workpiece during tapping, which makes the machine unable to process normally.
