DETAILED DESCRIPTION

[0034] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] Embodiment 1: A motorcycle luggage compartment cover forming device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig.10 As shown, it includes a processing table 1, a welding frame 101, an upper slide bar 102, an upper bracket 103, an upper spring 104, a No. 1 welding gun 105, a lower slide bar 106, a lower bracket 107, a lower spring 108, a No. 2 welding gun 109, an upper guide assembly and a lower guide assembly. The processing table 1 is fixed with the welding frame 101, the upper side of the welding frame 101 is slidably connected with the upper slide bar 102 in the vertical direction, the upper slide bar 102 is slidably connected with the upper bracket 103 in the vertical direction, the guide rod of the upper bracket 103 is sleeved with an upper spring 104, the upper bracket 103 is connected to the No. 1 welding gun 105 through the upper guide assembly, and when the upper slide bar 102 is close to the upper bracket 103 The upper spring 104 will be compressed, and the upper guide assembly will drive the No. 1 welding gun 105 to move in the horizontal direction, and the moving trajectory is parallel to the first weld 13. The lower side of the welding frame 101 is slidably connected to a lower slide rod 106 in the vertical direction, and the lower slide rod 106 is slidably connected to a lower bracket 107 in the vertical direction. A lower spring 108 is sleeved on the guide rod of the lower bracket 107, and the lower bracket 107 is connected to the No. 2 welding gun 109 through the lower guide assembly. When the lower slide rod 106 approaches the lower bracket 107, the lower spring 108 will be compressed, and the lower guide assembly will drive the No. 2 welding gun 109 to move tilted upward, and the moving trajectory is parallel to the second weld 12.

[0036] The sheet will be cut into Fig.10 The shape of the main body plate 10, Fig.10 The uppermost side is the shape of the main plate 10 when it is not bent. The main plate 10 is a whole plate. Then the worker uses a bending machine to bend the main plate 10. Fig.10It can be seen that there are gaps at the four corners of the upper side of the main plate 10 after bending. This is because the bending machine has some limitations in processing positions with too many angle changes. Therefore, the gaps are left here when designing the cutting shape of the main plate 10. However, in order to ensure the strength of the box cover, workers are required to weld the rectangular sealing plate 11 to the gaps after bending. In the welding process, it is usually divided into two stations. The first station places the sealing plate 11 at the gap and welds the vertical joints between the main plate 10 and the sealing plate 11 to seal the sealing plate 11. The two ends of the box cover are welded to the main plate 10, and then the worker at the second station welds the first weld 13 and the second weld 12. This method is to standardize the operation and ensure product quality and welding efficiency. When using this device to weld the box cover, the box cover is placed between the upper slide bar 102 and the lower slide bar 106, and then the upper slide bar 102 is controlled to drive the upper bracket 103 to slide downward, and the lower slide bar 106 is controlled to drive the lower bracket 107 to slide upward. When the No. 1 welding gun 105 moves to one end of the first weld 13, the upper bracket 103 stops moving downward. The second welding gun 109 moves to the lower end of the second welding seam 12, and the lower bracket 107 stops moving upward, then the upper slide bar 102 starts to move downward and close to the upper bracket 103, and the lower slide bar 106 starts to move upward and close to the lower bracket 107. In this process, the upper guide assembly drives the first welding gun 105 to move along the first welding seam 13, and the first welding seam 13 is welded by the first welding gun 105, and the lower guide assembly drives the second welding gun 109 to move obliquely upward along the second welding seam 12, and the second welding gun 109 welds the second welding seam 12 Welding is performed. After welding is completed, the upper slide bar 102 is controlled to reset upward, and the lower slide bar 106 is controlled to reset downward. Then the box cover is rotated 180 degrees to facilitate welding of the first weld 13 and the second weld 12 on the other side of the box cover. Then the upper slide bar 102 is controlled to move downward again, and the lower slide bar 106 is controlled to move downward. The subsequent steps are as described above. The No. 1 welding gun 105 welds the first weld 13, and the No. 2 welding gun 109 welds the second weld 12, thereby completing the welding of the four first welds 13 and the four second welds 12.

[0037] like Figure 2 and Figure 3As shown, the upper guide assembly includes an upper guide frame 2, an upper slide 201, an inclined spring 202, a No. 1 touch rod 203, a No. 2 touch rod 204, a force block 205, a force delivery plate 206 and a transverse spring 207. Two upper guide frames 2 are symmetrically fixed to the upper bracket 103. The two upper guide frames 2 are arranged in an eight-shaped shape. The upper guide frame 2 is slidably connected to the upper slide 201 in the horizontal direction. The No. 1 welding gun 105 is fixedly installed on the lower side of the upper slide 201. The guide rod of the upper slide 201 is sleeved with an inclined spring 202. The inclined spring 202 is used to push the upper slide 201 to reset. The upper slide 201 is fixedly connected with a No. 1 touch rod. Rod 203, the upper bracket 103 is symmetrically connected with two force blocks 205 in a sliding manner, the force blocks 205 slide in the horizontal direction, and a No. 2 touch rod 204 is fixedly connected to the force blocks 205. The No. 2 touch rod 204 pushes the No. 1 touch rod 203 to make the upper slide 201 drive the No. 1 welding gun 105 to move horizontally. A transverse spring 207 is sleeved on the guide rod of the force block 205. When the No. 2 touch rod 204 slides in the direction close to the No. 1 touch rod 203, the transverse spring 207 will be compressed. The upper slide bar 102 is fixedly connected with a force delivery plate 206, which is used to squeeze the force block 205 to drive the No. 2 touch rod 204 to move.

[0038] When the No. 1 welding gun 105 moves to one end of the first weld 13, the upper bracket 103 stops moving downward, the upper slide bar 102 drives the force plate 206 downward to approach the upper bracket 103, the upper spring 104 is compressed, and the force plate 206 squeezes the force blocks 205 on both sides, so that the force blocks 205 push the No. 2 touch rods 204 on both sides to move in opposite directions, the transverse spring 207 is also compressed, and the No. 2 touch rod 204 pushes the upper slide 201 to slide along the upper guide frame 2 through the No. 1 touch rod 203, and the sliding direction of the upper slide 201 is parallel to the first weld 1 3, thereby driving the No. 1 welding gun 105 to weld the first weld 13, and the inclined spring 202 will also be compressed; during the upward reset process of the upper slide bar 102, since the upper spring 104 is in a compressed state, the upper slide bar 102 will first drive the force feeding plate 206 upward away from the upper bracket 103, and the upper spring 104 gradually recovers, and the transverse spring 207 pushes the two No. 1 contact rods 203 to move relative to each other for reset, and the inclined spring 202 pushes the upper slide seat 201 to reset, and then the upper slide bar 102 drives the upper bracket 103 and the structure thereon to reset upward together.

[0039] like Figure 2 and Figure 4As shown, the lower guide assembly includes a lower guide frame 3, a lower sliding seat 301, a rear spring 302, a third contact rod 303 and a resistance block 304. Two lower guide frames 3 are symmetrically fixed on the lower bracket 107. The lower guide frame 3 is tilted. The lower guide frame 3 is slidably connected with the lower sliding seat 301. The No. 2 welding gun 109 is fixedly installed on the lower sliding seat 301. The rear spring 302 is sleeved on the guide rod of the lower sliding seat 301. When the lower sliding seat 301 slides obliquely upward, the rear spring 302 will be compressed. The third contact rod 303 is fixed on the lower sliding seat 301. The resistance block 304 is fixed on the lower lower rod 106. The resistance block 304 is used to push the No. 3 contact rod 303 so that the lower sliding seat 301 drives the No. 2 welding gun 109 to move obliquely upward.

[0040] When the No. 2 welding gun 109 moves to the lower end of the second welding seam 12, the lower bracket 107 stops moving upward, the lower slide rod 106 will drive the resistance block 304 to continue to move upward, the lower spring 108 will be compressed, and the resistance block 304 will squeeze the No. 3 touch rod 303, so that the No. 3 touch rod 303 drives the lower slide seat 301 to slide upward along the lower guide frame 3, thereby driving the No. 2 welding gun 109 to weld the second welding seam 12, and the rear spring 302 will also be compressed; in the process of the lower slide rod 106 returning downward, since the lower spring 108 is in a compressed state, the lower slide rod 106 will first drive the resistance block 304 downward away from the No. 3 touch rod 303, the lower spring 108 gradually recovers, and the rear spring 302 pushes the lower slide seat 301 to return downward along the lower guide frame 3, and then the lower slide rod 106 drives the lower bracket 107 and the structure thereon to return downward together.

[0041] like Figure 1 and Figure 2 As shown, there is also a limit assembly for limiting the moving height of the upper bracket 103 and the lower bracket 107. The limit assembly is connected to the upper bracket 103 and the lower bracket 107. The limit assembly includes a resistance plate 4, an upper baffle 401 and a lower baffle 402. Two resistance plates 4 are fixedly connected to the welding frame 101. The two resistance plates 4 are located between the upper bracket 103 and the lower bracket 107. The upper baffle 401 is fixedly connected to the upper bracket 103, and the lower baffle 402 is fixedly connected to the lower bracket 107. The upper resistance plate 4 limits the downward movement height of the upper bracket 103 by blocking the upper baffle 401, and the lower resistance plate 4 limits the upward movement height of the lower bracket 107 by blocking the lower baffle 402.

[0042] When welding gun No. 105 moves to one end of the first weld 13, the upper baffle plate 401 will contact the resistance plate 4 on the upper side, thereby preventing the upper bracket 103 from continuing to move downward through the resistance plate 4 on the upper side. When welding gun No. 2 109 moves to the lower end of the second weld 12, the lower baffle plate 402 will contact the resistance plate 4 on the lower side, thereby preventing the lower bracket 107 from continuing to move upward through the resistance plate 4 on the lower side.

[0043] like Figure 1 and Figure 2 As shown, it also includes a driving mechanism for driving the upper slide bar 102 and the lower slide bar 106 to move, the driving mechanism is connected to the upper slide bar 102 and the lower slide bar 106, the driving mechanism includes an electric push rod 5, an upper rack 501, a middle gear 502 and a lower rack 503, the welding frame 101 is fixedly connected to the electric push rod 5, the telescopic shaft of the electric push rod 5 passes through the top of the welding frame 101 and is fixedly connected to the top of the upper slide bar 102, the upper rack 501 is fixedly connected to the upper slide bar 102, the middle gear 502 is rotatably connected to the welding frame 101, the lower rack 503 is fixedly connected to the lower slide bar 106, and the middle gear 502 is meshed with the upper rack 501 and the lower rack 503 at the same time.

[0044] When the telescopic shaft of the electric push rod 5 is extended, it will drive the upper slide bar 102 to slide downward, and the upper slide bar 102 will drive the lower slide bar 106 to slide upward through the upper rack 501, the middle gear 502 and the lower rack 503. When the telescopic shaft of the electric push rod 5 is retracted, it will drive the upper slide bar 102 to slide upward and drive the lower slide bar 106 to slide downward.

The reversing ratchet 7 will drive the reversing ratchet 702 to rotate only when it slides in the direction away from the lower slide rod 106, and at this time the reversing spring 701 will be compressed. The processing table 1 is slidably connected with a contact plate 703 in the horizontal direction, and a contact spring 704 is sleeved on the guide rod of the contact plate 703. When the contact plate 703 slides in the direction close to the reversing ratchet 7, the contact spring 704 will be compressed. A driven ratchet 705 is fixedly connected to the upper end of the contact plate 703. A transmission ratchet 706 is rotatably connected to the welding frame 101, and the transmission ratchet 706 and the driven ratchet 705 are meshed. A transmission ratchet 707 is fixedly connected to the upper slide bar 102 through a long rod, and the transmission ratchet 707 and the transmission ratchet 706 can be meshed. The driven ratchet 705, the transmission ratchet 707 and the transmission ratchet 706 are also ratchet-ratche structures. When the transmission ratchet 707 moves upward, it will drive the contact plate 703 to slide in the direction close to the reversing ratchet 7 through the transmission ratchet 706 and the driven ratchet 705.

[0048] After the electric slide 601 slides in the direction close to the lower slide bar 106, the reversing ratchet 7 will contact the contact plate 703. After the weld on one side is completed and the upper slide bar 102 slides upward, the upper slide bar 102 will drive the transmission ratchet 707 to move upward. When the No. 1 welding gun 105 and the No. 2 welding gun 109 are moved away from the rotation range of the box cover, the transmission ratchet 707 will begin to engage with the transmission ratchet 706. The transmission ratchet 706 drives the contact plate 703 to slide in the direction of the reversing ratchet 7 through the driven ratchet 705, so that the contact plate 703 pushes the reversing ratchet 7 to slide, the contact spring 704 and the reversing spring 701 are compressed, and the reversing ratchet 7 will drive the reversing shaft 604 to rotate clockwise through the reversing ratchet 702 The electric slide 601 moves 180 degrees, thereby driving the welding table 603 and the box cover thereon to rotate 180 degrees, and then the transmission ratchet 707 and the transmission ratchet 706 are disengaged, and the resistance spring 704 and the reversing spring 701 push the resistance plate 703 and the reversing ratchet 7 to reset. During the resetting process of the reversing ratchet 7, the reversing ratchet 7 will not drive the reversing ratchet 702 to rotate, and the reversing ratchet 7 after resetting will disengage from the reversing ratchet 702; when the electric slide 601 moves downward again to start welding the first weld 13 and the second weld 12 on the other side, since the resistance plate 703 has been reset and the transmission ratchet 707 and the transmission ratchet 706 are ratchet-ratchet structures, the transmission ratchet 707 will not drive the transmission ratchet 706 to rotate.

[0049] Embodiment 3: Based on embodiment 2, Figure 1 , Figure 8 and Fig. 9As shown, it also includes a feeding mechanism for automatically feeding the box cover, the feeding mechanism is connected to the electric slide 601, the feeding mechanism includes a material box 8, a support frame 801, a material control guide frame 802, a lower connecting rod 803, a lower supporting plate 804, an upper connecting rod 805, an upper clamping plate 806, a reset spring 807, a buffer spring 811 and a driven component, the processing table 1 is fixed with a material box 8, and two support frames 801 are symmetrically fixed on the material box 8, and the support frame 801 is L-shaped. The support frame 801 is slidably connected with a material control guide frame 802 in the vertical direction, and two slide grooves are provided on the material control guide frame 802, and the two slide grooves are arranged in an eight-shaped shape. A lower connecting rod 803 is slidably connected in the slide groove on the lower side of the material control guide frame 802, and a lower supporting plate 804 is fixedly connected to the end of the lower connecting rod 803 away from the material control guide frame 802. The lower supporting plate 804 is slidably connected to the material box 8 in the horizontal direction, and the lower supporting plate 804 can pass through the side wall of the material box 8 and extend inward, and the material control guide frame An upper connecting rod 805 is slidably connected in the slide groove on the upper side of 802, and an upper clamping plate 806 is slidably connected to the end of the upper connecting rod 805 away from the slide groove. The upper clamping plate 806 is slidably connected to the material box 8 in the horizontal direction, and the upper clamping plate 806 can also pass through the side wall of the material box 8 and extend inward. A buffer spring 811 is sleeved on the guide rod of the upper clamping plate 806. When the upper clamping plate 806 approaches the upper connecting rod 805, the buffer spring 811 will be compressed, and when the material control guide frame 802 slides upward, The upper clamping plate 806 is driven to extend into the material box 8 to clamp the upper box cover, and the lower support plate 804 will slide out of the material box 8 to loosen the lower box cover. A return spring 807 is provided on the guide rod of the material control guide frame 802. When the material control guide frame 802 slides upward, the return spring 807 will be compressed. A driven component is connected to the electric slide 601. When the electric slide 601 moves downward in the direction of the slide rod 106, the driven component will push the material control guide frame 802 upward.

[0050] Before using the device, workers will stack the box covers to be welded into the material box 8, and the bottom box cover will fall on the lower support plate 804, which can prevent the box cover from falling out. When the electric slide 601 slides in the direction close to the lower slide rod 106, the driven component will drive the material control guide 802 to slide upward, and the material control guide 802 will drive the lower support plate 804 to move away from under the box cover through the lower connecting rod 803. At the same time, the material control guide 802 will drive the upper clamping plate 806 to enter the material box through the upper connecting rod 805. In the box 8, the upper clamping plate 806 will clamp the side wall of the second box cover from the bottom to the top, so that the bottom box cover can fall down onto the welding table 603, while the upper box cover will not fall down; when the driven component cancels the force on the material control guide 802, the reset spring 807 pushes the material control guide 802 to reset downward, and the material control guide 802 drives the upper clamping plate 806 and the lower support plate 804 to reset, and the upper clamping plate 806 releases the box cover to make the box cover fall down onto the lower support plate 804, so as to facilitate re-loading; Figure 8It can be seen that the lower support plate 804 extends into the material box 8 for a longer distance, so the distance required to withdraw is also longer. Since the upper clamping plate 806 clamps the side wall of the box cover, the distance that the upper clamping plate 806 extends into the material box 8 is shorter. Therefore, the buffer spring 811 is provided to provide buffer protection. When producing this device, technicians can increase the height of the upper clamping plate 806 so that the upper clamping plate 806 can clamp multiple box covers on the lower side at the same time.

[0051] like Figure 5 and Figure 8 As shown, the driven assembly includes an upper ejector block 808, a lower ejector block 809 and a torsion spring 810. The upper ejector block 808 is fixedly connected to the lower side of the material control guide frame 802. Two brackets are vertically arranged on the electric slide 601. The brackets are rotatably connected to the lower ejector block 809. The torsion spring 810 is sleeved on the rotating shaft of the lower ejector block 809. One end of the torsion spring 810 is fixedly connected to the bracket, and the other end of the torsion spring 810 is fixedly connected to the lower ejector block 809. The rotation range of the lower ejector block 809 is limited, as shown in FIG. Figure 5 The state of the middle and lower top block 809 is that the lower top block 809 can be rotated ninety degrees clockwise first and then rotated counterclockwise to reset, but cannot be rotated directly counterclockwise, so that the lower top block 809 can press the upper top block 808 upward during the movement in the direction of the downward slide rod 106.

[0052] When the upper and lower push blocks 808 and 809 are out of contact, the material control guide frame 802 will be reset downward; during the sliding reset process of the electric slide 601 in the direction away from the sliding rod 106, the upper push block 808 will push the lower push block 809 to rotate clockwise, and the torsion spring 810 will be charged, that is, the material control guide frame 802 will not move upward during the reset process of the electric slide 601, and when the upper and lower push blocks 808 and 809 are out of contact, the torsion spring 810 drives the lower push block 809 to rotate and reset.

[0053] like Figure 5 , Figure 6 and Figure 7 As shown, it also includes a positioning mechanism for positioning the box cover, the positioning mechanism is connected to the reversing shaft 604, and the positioning mechanism includes a positioning clamp 9, a positioning plate 901, a slide 902, an outer push rod 903 and an inner stop rod 904. Figure 7As can be seen, four cross-shaped slide grooves are provided at the lower side of the welding platform 603, and a positioning clip 9 is slidably connected in each slide groove. The positioning clip 9 extends to the upper side of the welding platform 603. A positioning plate 901 is fixedly connected to the reversing shaft 604, and four slideways 902 are provided on the positioning plate 901. The lower side of each positioning clip 9 is slidably connected to one of the slideways 902. When the positioning plate 901 rotates, it can drive the four positioning clips 9 to expand or contract. A ring array is fixedly connected to the outer wall of the upper side of the reversing shaft 604. There are four outer push rods 903, and a through hole is opened in the middle of the welding table 603. Four inner blocking rods 904 are fixedly connected to the inner wall of the through hole in a circular array. The swivel 602 and the reversing shaft 604 are both connected to the electric slide 601 in a damping rotation manner, so that the swivel 602 and the reversing shaft 604 cannot rotate at will. The reversing shaft 604 can first drive the positioning plate 901 to rotate alone to position the box cover through the positioning clamp 9, and then drive the welding table 603 to rotate through the outer push rods 903 and the inner blocking rods 904 to adjust the direction of the box cover.

[0054] from Figure 5 It can be seen that the outer push rod 903 can only contact the next inner stop rod 904 after the reversing shaft 604 rotates clockwise by a certain angle. This angle is set to 45 degrees. When the electric slide 601 moves toward the direction close to the slide rod 106, Figure 1 It can be seen from the figure that the contact plate 703 after reset cannot slide in the direction away from the reversing ratchet 7, so the reversing ratchet 7 will be blocked by the contact plate 703 first, and the electric slide 601 will continue to move in the direction close to the lower slide rod 106, so that the reversing ratchet 7 will first drive the reversing shaft 604 to rotate 45 degrees clockwise. Since the swivel 602 and the electric slide 601 are connected in a damping rotation manner, and the reversing shaft 604 is not in direct contact with the welding table 603 and the swivel 602, the reversing shaft 604 can first drive the four positioning clips 9 to contract through the positioning plate 901, and the positioning clips 9 can play a role in positioning the box cover on the welding table 603. After the reversing shaft 604 rotates 45 degrees clockwise, the outer The push rod 903 will contact the next inner stop rod 904. When the contact plate 703 actively pushes the reversing ratchet 7, the reversing ratchet 7 will drive the reversing shaft 604 to continue to rotate 180 degrees clockwise through the reversing ratchet 702. At this time, the reversing shaft 604 will drive the welding table 603 and the swivel 602 to rotate 180 degrees synchronously through the outer push rod 903 and the inner stop rod 904, thereby driving the box cover to adjust the direction; when the electric slide 601 is reset in the direction away from the lower slide rod 106, when the worker takes the box cover, the worker pulls the four positioning clips 9 outward to reset them, so that the four positioning clips 9 are away from the box cover, and the positioning clips 9 will drive the reversing shaft 604 to rotate 45 degrees counterclockwise to reset through the positioning plate 901.
