The upper end surface of the spring telescopic plate is symmetrically installed with a fixed plate, and the upper end surface of the fixed plate is rotatably installed with a second round rod for supporting the quartz rod; when the electric telescopic rod drives the spring telescopic plate to rise, the spring telescopic plate drives the quartz rod to rise through the fixed plate and the second round rod, and at this time, the positioning assembly centers the quartz rod, and then the clamping assembly clamps the positioned quartz rod;

[0008] The positioning assembly includes a groove formed on the outer wall of the support rod and a tension spring symmetrically installed on the lower end surface of the spring telescopic plate, the lower end surface of the tension spring is installed with a support plate, the upper end surface of the support plate is symmetrically installed with a fifth round rod, and the upper end surface of the fifth round rod penetrates the spring telescopic plate and is installed with a baffle; when the spring telescopic plate rises, the fourth round rod moves into the groove, and at this time the baffles move toward each other to position the quartz rod;

[0010] Preferably, the moving component includes a servo motor, which is mounted on the outer wall of the support frame. The output shaft of the servo motor passes through the support frame and is fixedly mounted with a bidirectional screw. The outer wall of the bidirectional screw is symmetrically threaded with a support block. The upper end surface of the support block is fixedly connected to the support rod.

At this time, the electric telescopic rod extends to push the spring telescopic plate to rise, and the spring telescopic plate drives the fourth round rod to rise. When the fourth round rod moves to the groove, the spring telescopic plate contracts. At this time, the baffle will position the quartz rod to make it centered to prevent uneven force on both sides, and when multiple quartz rods need to be welded, the remaining quartz rods can quickly enter between the quartz plates;

[0020] Second, the present invention sets a clamping assembly. When the spring telescopic plate rises, the fixed plate and the second round rod drive the quartz rod to rise. At this time, the fixed plate drives the third round rod and the pull rope to rise. As the pull rope is gradually tightened, the pull rope drives the third round rod to rotate due to the adsorption of the magnetic block on the second cylinder. The third round rod drives the clamping claw to rotate, thereby clamping the quartz rods of different specifications after positioning. When the clamping claw completely clamps the quartz rod, the pull rope continues to rise and drives the magnetic block to move up in the second cylinder. At this time, the clamping claw always clamps the quartz rod to keep it centered to prevent deviation.

[0021] 3. The present invention provides a baffle, and when the baffle abuts against the clamp, the clamp can be fixed to prevent the clamp from rotating in the support ring, thereby improving welding accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] See also Figures 1 to 5 The present invention provides a technical solution: a quartz boat assembly forming welding tool, comprising a support frame 2, a moving assembly and a support rod 26 symmetrically arranged above the moving assembly, a clamp 4 is installed above the support rod 26, and further comprising:

[0029] The lifting mechanism is arranged between the support rods 26, and includes a positioning assembly, a clamping assembly and a spring telescopic plate 12. The electric telescopic rod 14 is symmetrically installed on the lower end surface of the spring telescopic plate 12. The fourth round rod 22 is rotatably installed on both ends of the spring telescopic plate 12 through the support rod 26. The fixing plate 16 is symmetrically installed on the upper end surface of the spring telescopic plate 12. The second round rod 17 for supporting the quartz rod 6 is rotatably installed on the upper end surface of the fixing plate 16; when the electric telescopic rod 14 drives the spring telescopic plate 12 to rise, the spring telescopic plate 12 drives the quartz rod 6 to rise through the fixing plate 16 and the second round rod 17. At this time, the positioning assembly centers the quartz rod 6, and then the clamping assembly clamps the positioned quartz rod 6;

[0030] The positioning assembly includes a groove 27 provided on the outer wall of the support rod 26 and a tension spring 25 symmetrically installed on the lower end surface of the spring telescopic plate 12, the lower end surface of the tension spring 25 is installed with a support plate 24, the upper end surface of the support plate 24 is symmetrically installed with a fifth round rod 23, and the upper end surface of the fifth round rod 23 penetrates the spring telescopic plate 12 and is installed with a baffle 21; when the spring telescopic plate 12 rises, the fourth round rod 22 moves into the groove 27, and at this time, the baffle 21 moves toward each other to position the quartz rod 6;

[0031] The clamping assembly includes a second cylinder 29 installed on the lower end surface of the support frame 2, a magnetic block 15 is slidably installed on the inner wall of the second cylinder 29, a pull rope 20 is installed on the upper end surface of the magnetic block 15, and the pull rope 20 is divided into two parts at one end away from the magnetic block 15, and a third round rod 19 is installed on each of the two ends, and a clamping claw 18 is symmetrically installed on the upper end surface of the third round rod 19. Both ends of the third round rod 19 are rotatably installed on the fixed plate 16, and a torsion spring is installed at the rotating connection; when the spring telescopic plate 12 rises, the outer wall of the magnetic block 15 is adsorbed on the second cylinder 29, and the pull rope 20 remains stationary, and the third round rod 19 is pulled to drive the clamping claw 18 to rotate, thereby clamping the quartz rod 6;

[0032] Further, such as Figure 1 As shown, the moving assembly includes a servo motor 1, which is mounted on the outer wall of the support frame 2. The output shaft of the servo motor 1 passes through the support frame 2 and is fixedly mounted with a bidirectional screw rod 9. The outer wall of the bidirectional screw rod 9 is symmetrically threaded with a support block 8. The upper end surface of the support block 8 is fixedly connected to the support rod 26. The support block 8 is slidably mounted with a first round rod 10 at one end away from the bidirectional screw rod 9. Both ends of the first round rod 10 are mounted on the support frame 2.

[0033] When the servo motor 1 rotates, the bidirectional screw rod 9 is driven to rotate. Since the bidirectional screw rod 9 is threadedly connected to the support block 8, the support block 8 moves on the first round rod 10 to adjust the position between the clamps 4.

[0034] Further, such as Figure 1 As shown, a support ring 5 is installed on the upper end surface of the support rod 26, the inner wall of the support ring 5 is rotatably connected to the clamp 4, and a turning handle 3 is installed on the side of the clamp 4 away from the quartz plate 7;

[0035] The clamp 4 can be rotated in the support ring 5 by turning the handle 3, so as to adjust the angle of the quartz plate 7 conveniently;

[0036] Further, such as Figure 1 As shown, a through hole is provided at the center of the spring expansion plate 12 for the passage of the pull rope 20;

[0037] Further, such as Figure 1 As shown, the outer wall of the support rod 26 is provided with a slide groove, and the slide groove is slidably connected with the spring telescopic plate 12;

[0038] Further, such as Figure 3 As shown, a first cylinder 28 is installed on the lower end surface of the spring expansion plate 12, and the first cylinder 28 is made of plastic;

[0039] The first cylinder 28 can squeeze the magnetic block 15, so that the magnetic block 15 descends in the second cylinder 29 and returns to the initial position;

[0040] Further, such as Figure 1 As shown, the support frame 2 is provided with an opening corresponding to the first cylinder 28, which is adapted to the size of the first cylinder 28 and is used for the first cylinder 28 to pass through;

[0041] Furthermore, the second cylinder 29 is made of iron, and the clamping jaw 18 is made of rubber;

[0042] When the magnet 15 is attracted in the second cylinder 29, as the pull rope 20 is tightened, the third round rod 19 will compress the torsion spring and rotate, and the clamping jaws 18 will clamp the quartz rod 6, and the rubber material will prevent it from being damaged;

[0043] Further, such as Figure 1 As shown, a plurality of supporting legs 13 are installed on the lower end surface of the support frame 2 for supporting the whole device, and a control panel 11 is installed on the upper end surface of the support frame 2 for setting relevant parameters and controlling the operation of the device;

[0044] Further, such as Figure 4 As shown, the clamping jaws 18 are arranged in a staggered manner.

[0045] Working principle: Step 1: After the external power supply is connected, the quartz plate 7 is first clamped by the clamp 4 (the existing technology), and then the welding position of the quartz plate 7 can be adjusted by turning the handle 3, and then the distance between the two quartz plates 7 is set through the control panel 11. At this time, the servo motor 1 rotates to drive the bidirectional screw 9 to rotate, and the bidirectional screw 9 drives the support block 8 to move. The support block 8 drives the clamp 4 to move through the support rod 26 support ring 5. At this time, the support rod 26 will drive the spring telescopic plate 12 to move synchronously. When it reaches the specified position, the servo motor 1 stops rotating;

[0046] Step 2: Place the quartz rod 6 on the second round rod 17, and then set the height of the quartz rod 6 through the control panel 11. At this time, the electric telescopic rod 14 extends to push the spring telescopic plate 12 to rise, and the spring telescopic plate 12 drives the fourth round rod 22 to rise. When the fourth round rod 22 moves to the groove 27, the spring telescopic plate 12 contracts. At this time, the baffle 21 will position the quartz rod 6 to make it centered. When the fourth round rod 22 moves up and away from the groove 27, the spring telescopic plate 12 stretches to the initial state;

[0047] When the fourth round rod 22 moves upward and away from the groove 27, the spring expansion plate 12 is extended, and the baffle 21 returns to the initial position. As the spring expansion plate 12 rises, the upper end of the baffle 21 abuts against the clamp 4 to fix the clamp 4 to prevent it from rotating. As the baffle 21 rises, the baffle 21 stretches the tension spring 25 through the fifth round rod 23 and the support plate 24.

[0048] When the spring telescopic plate 12 rises, the quartz rod 6 is driven to rise through the fixed plate 16 and the second round rod 17. At this time, the fixed plate 16 drives the third round rod 19 and the pull rope 20 to rise. At this time, since the pull rope 20 is relaxed and naturally folded to form wrinkles or bends, the pull rope 20 will not be subjected to force. When the quartz rod 6 is centered, as the quartz rod 6 rises, the pull rope 20 is gradually tightened, which will drive the third round rod 19 to rotate. The third round rod 19 drives the clamping claw 18 to rotate to clamp the positioned quartz rod 6. When the clamping claw 18 completely clamps the quartz rod 6, the pull rope 20 continues to rise and drives the magnetic block 15 to move up in the second cylinder 29. At this time, the clamping claw 18 always clamps the quartz rod 6, and can clamp quartz rods 6 of different specifications. When the quartz rod 6 reaches the specified height, it stops. At this time, the positioning and clamping of the quartz rod 6 are completed;

[0049] Step 3: After the quartz rod 6 is welded, the electric telescopic rod 14 is controlled to descend, and the electric telescopic rod 14 drives the spring telescopic plate 12 to descend, and the spring telescopic plate 12 drives the first cylinder 28 and the third round rod 19 to descend. At this time, the torsion spring in the third round rod 19 rotates, driving the third round rod 19 to rotate in the opposite direction, and the third round rod 19 drives the clamping claw 18 to rotate, and the clamping claw 18 no longer clamps the quartz rod 6. As the spring telescopic plate 12 descends, the first cylinder 28 will squeeze the magnetic block 15 downward, and the magnetic block 15 descends back to the initial position in the second cylinder 29. At this time, the pull rope 20 will relax again and then fold naturally to form wrinkles or bends. When welding other quartz rods 6, repeat the second step. In this process, there is no need to adjust the position of the quartz rod 6 separately, and it can also smoothly enter between the quartz plates 7, thereby improving assembly efficiency.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
