Description

Technical Field

[0001] This utility model belongs to the field of flat fork production technology, specifically a flat fork production fixing device. Background Technology

[0002] The swingarm is an important component of a motorcycle structure. Its main function is to support the weight of the entire vehicle and ensure the stability and correct position of the rear wheel.

[0003] Existing motorcycle swingarm manufacturing and fixing devices mostly include structures such as bases and clamps. When fixing the motorcycle swingarm, the lateral movement of the clamps is used to clamp and fix the motorcycle swingarm.

[0004] However, the clamping structure of the current motorcycle swingarm production fixing device is not flexible enough. That is, it is difficult to adjust the position and angle of the swingarm according to the actual use needs during the subsequent processing of the motorcycle swingarm, which affects the further processing of the motorcycle swingarm and reduces the production efficiency of motorcycle swingarm.

[0005] Therefore, a flat fork production fixing device is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a flat fork production fixing device.

[0007] The technical solution adopted by this utility model to solve its technical problem is a flat fork production fixing device, including a base, a first motor is provided at the top center of the base, and the output end of the first motor is connected to a rotating seat. An annular groove is opened at the top of the base, a connecting rod is installed on one side of the bottom of the rotating seat, and an auxiliary wheel is connected to the bottom of the connecting rod. A cylinder is provided in the inner cavity of the rotating seat, and an adjustment structure is connected to one end of the cylinder.

[0008] The adjustment structure includes a movable block fixedly installed at one end of the cylinder, and a movable seat is provided at the top of the movable block. A movable block is provided in the inner cavity of the movable seat, and a guide block is installed at one end of the movable block. A movable rod is connected to the side wall of the movable block, and a first spring is sleeved on the outer surface of the movable rod. An adjustment block is connected to the other end of the movable rod, and an adjustment seat is provided at the top of the adjustment block. A second motor is installed on the side wall of the adjustment seat, and a flipping seat is connected to the output end of the second motor.

[0009] Preferably, a second spring is fixedly connected to the inner side wall of the flipping seat, and a rubber head is fixedly connected to the other end of the second spring.

[0010] Preferably, the connecting rods are equidistantly distributed along the center point of the rotating seat, and the auxiliary wheel is rotatably connected to the connecting rod. The auxiliary wheel can improve the stability of the rotating seat during movement.

[0011] Preferably, the moving block is slidably connected to the rotating seat via the cylinder, and the moving block is symmetrically distributed along the vertical center line of the rotating seat.

[0012] Preferably, the movable block is slidably connected to the movable seat via the guide block, and the movable rod is perpendicular to the movable block. The lateral movement of the movable block will drive the guide block to move laterally along the movable seat, thereby improving the stability of the movable block during its movement.

[0013] Preferably, the rubber heads are equidistantly distributed along the center point of the flipping seat, and the rubber heads are slidably connected to the flipping seat through the second spring. When the rubber heads move laterally, they will squeeze the second spring, which facilitates the subsequent use of the second spring to assist the rubber heads in lateral reset.

[0014] The advantages of this utility model are:

[0015] 1. This utility model, through the structure of motor, rotating seat, cylinder, moving seat and adjusting seat, can facilitate the effective clamping and limiting of the flat fork according to the actual size, ensuring the stability of the flat fork during subsequent processing. At the same time, it can also realize the rotation or flipping of the flat fork during processing, thereby improving the flexibility of the entire device.

[0016] 2. This utility model, through the setting of rubber heads and second springs, can ensure the stability of clamping the flat fork when clamping it. Since the flat fork is irregularly shaped, when the flat fork comes into contact with the rubber head, it will push the rubber head, causing it to squeeze the second spring. Since the rubber heads are evenly distributed along the center point of the flip seat, the combination of multiple rubber heads and second springs can effectively clamp and fix the irregular flat fork.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-5 As shown, a flat fork production fixing device includes a base 1, a first motor 2 is provided at the top center of the base 1, and the output end of the first motor 2 is connected to a rotating seat 3. An annular groove 4 is provided at the top of the base 1, a connecting rod 5 is installed on one side of the bottom of the rotating seat 3, and an auxiliary wheel 6 is connected to the bottom of the connecting rod 5. A cylinder 7 is provided in the inner cavity of the rotating seat 3, and an adjustment structure is connected to one end of the cylinder 7.

[0026] The adjustment structure includes a movable block 8 fixedly installed at one end of the cylinder 7, and a movable seat 9 is provided at the top of the movable block 8. A movable block 10 is provided in the inner cavity of the movable seat 9, and a guide block 11 is installed at one end of the movable block 10. A movable rod 12 is connected to the side wall of the movable block 10, and a first spring 13 is sleeved on the outer surface of the movable rod 12. An adjustment block 14 is connected to the other end of the movable rod 12, and an adjustment seat 15 is provided at the top of the adjustment block 14. A second motor 16 is installed on the side wall of the adjustment seat 15, and a flip seat 17 is connected to the output end of the second motor 16.

[0027] During operation, cylinder 7 drives moving block 8 to slide laterally in the groove on the surface of rotating seat 3. The lateral movement of moving block 8 causes moving seat 9 to move laterally as well, thus adjusting the lateral position of flip seat 17. The flip seat 17, in conjunction with rubber head 19, clamps and fixes the flat fork to be processed. Simultaneously, under the reverse force, flip seat 17 causes adjusting block 14 to push moving rod 12 laterally. Moving rod 12 then causes moving block 10, fixedly connected to its other end, to slide laterally inside moving seat 9. The movement of moving block 10 also causes guide block 11 to move laterally as well. Lateral movement is performed to improve the stability of the movable rod 12 during movement. At the same time, the first spring 13 deforms under the action of the movable rod 12 and the movable block 10, which can further play the purpose of buffering and protection. When the second motor 16 works, it will realize the flipping seat 17 to achieve the flipping process of the flat fork, so as to facilitate better processing of the flat fork in the future. When the first motor 2 works, it will cause the rotating seat 3 connected to its output end to rotate. When the rotating seat 3 rotates, it will cause the connecting rod 5 to drive the auxiliary wheel 6 to move inside the annular groove 4, thereby improving the stability of the rotating seat 3 during movement.

[0028] A second spring 18 is fixedly connected to the inner side wall of the flip seat 17, and a rubber head 19 is fixedly connected to the other end of the second spring 18.

[0029] During operation, when the flip seats 17 on both sides move laterally, they will cause the rubber heads 19 to move laterally as well, thus bringing the rubber heads 19 into contact with the surface of the flat fork. When the two come into contact, the lateral movement of the rubber heads 19 compresses the second spring 18 and causes it to deform. The reverse force generated by the deformation of the second spring 18 not only serves as a buffer and protection, but also allows the rubber heads 19 to make better contact with the surface of the flat fork. Since multiple rubber heads 19 are equidistantly arranged along the center of the flip seat 17, the multiple rubber heads 19 arranged in combination can effectively clamp and fix the flat fork.

[0030] The connecting rods 5 are equidistantly distributed along the center point of the rotating seat 3, and the auxiliary wheel 6 is rotatably connected to the connecting rods 5;

[0031] When the rotating seat 3 rotates, the connecting rod 5 will drive the auxiliary wheel 6 to rotate inside the annular groove 4, thereby improving the stability of the rotating seat 3 during its movement by using the connecting rod 5 and the auxiliary wheel 6.

[0032] The movable block 8 is slidably connected to the rotating seat 3 via the cylinder 7, and the movable block 8 is symmetrically distributed along the vertical center line of the rotating seat 3;

[0033] During operation, cylinder 7 pushes the moving block 8 laterally, and the lateral position of the flip seat 17 can be adjusted by the lateral movement of the moving block 8.

[0034] The movable block 10 is slidably connected to the movable seat 9 via the guide block 11, and the movable rod 12 is perpendicular to the movable block 10.

[0035] When the movable block 10 moves laterally during operation, it will drive the guide block 11 to move laterally along the moving seat 9, thereby improving the stability of the movable block 10 during the lateral movement process.

[0036] The rubber heads 19 are evenly distributed along the center point of the flip base 17, and the rubber heads 19 are slidably connected to the flip base 17 through the second spring 18.

[0037] During operation, the rubber head 19 moves laterally and compresses the second spring 18 fixedly connected to one end, which facilitates the subsequent reaction force generated by the deformation of the second spring 18 to make the rubber head 19 better contact with the surface of the flat fork.

[0038] The working principle is as follows: the flat fork to be processed is placed on the upper surface of the rotating seat 3. At this time, the cylinder 7 drives the moving block 8 to slide laterally in the groove opened on the surface of the rotating seat 3. When the moving block 8 moves laterally, it will drive the moving seat 9 to move laterally as well. This is to use the lateral movement of the moving seat 9 to adjust the lateral position of the flip seat 17. When the flip seats 17 on both sides move laterally, they will drive the rubber head 19 to move laterally as well, so that the rubber head 19 contacts the surface of the flat fork. When the two are in contact, the lateral movement of the rubber head 19 compresses the second spring 18 and causes it to deform. The reverse force generated by the deformation of the second spring 18 can not only play a role in buffering and protection, but also make the rubber head 19 contact the surface of the flat fork better. Since multiple rubber heads 19 are equally spaced along the center of the flip seat 17, the multiple rubber heads 19 can effectively clamp and fix the flat fork. Under the reverse force, the flip seat 17 will cause the adjusting block 14 to push the movable rod 12 laterally. Then, the movable rod 12 will drive the movable block 10, which is fixedly connected to its other end, to slide laterally inside the movable seat 9. At the same time, the movable block 10 will drive the guide block 11 to move laterally, thereby improving the stability of the movable rod 12 during movement. Meanwhile, the first spring 13 will also deform under the action of the movable rod 12 and the movable block 10, thereby further serving as a buffer and protection. When the second motor 16 works, it will flip the flip seat 17 to achieve the flipping of the flat fork, which will facilitate better processing of the flat fork in the future. When the first motor 2 works, it will cause the rotating seat 3 connected to its output end to rotate. When the rotating seat 3 rotates, it will cause the connecting rod 5 to drive the auxiliary wheel 6 to move inside the annular groove 4, thereby improving the stability of the rotating seat 3 during movement.
