[0002] Motorcycle lights, as an important component of motorcycles, not only serve a lighting function but also bear the responsibility of signal transmission, which is crucial for ensuring driving safety.

[0003] Currently, in the production process of motorcycle lights, fixtures are often used for positioning to assist in processing. Existing motorcycle lights come in various shapes and sizes. Traditional fixing fixtures achieve the positioning effect by contacting the outer wall of the light with a single clamping block. However, in actual applications, such traditional fixtures have a small contact surface, which makes them prone to falling off, displacement, and instability. Moreover, one fixture only corresponds to one type of car light. To process different types of car lights, different fixtures need to be changed, which affects work efficiency and is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning fixture for processing motorcycle lights.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning fixture for processing motorcycle lights includes a mounting platform. A lifting plate is provided in the middle of the mounting platform. The lifting plate is driven to rise and fall by a lead screw. Multiple sets of positioning columns are provided on the workpiece clamping surfaces of the lifting plate and the mounting platform. Positioning rubber blocks are provided on the positioning columns to position the workpiece.

[0007] A screw is provided in the middle of the positioning column, and an adjusting cylinder is screwed onto the screw. A rotating block is installed on the top of the adjusting cylinder. A pair of positioning rubber blocks are installed in the middle of the rotating block by means of a column. One side of the positioning rubber blocks is locked by a fastener, and the positioning rubber blocks are vertically limited and slidably installed on the column by means of a sliding groove.

[0008] Furthermore, in a preferred configuration, the lead screw is screwed to the mounting platform, and the bottom end of the lead screw extends downward and is rotatably connected to the lifting plate.

[0009] Furthermore, in a preferred configuration, when the adjusting cylinder rotates relative to the screw, the adjusting cylinder slides vertically inside the positioning post;

[0010] One side of the positioning post is screwed with a fastener, and one end of the fastener extends into the interior of the positioning post and presses against the outer wall of the adjusting cylinder.

[0011] Furthermore, in a preferred configuration, a spring element is provided between the adjusting cylinder and the positioning column.

[0012] In addition, a preferred structure is that a rotating block is rotatably mounted on the upper part of the adjusting cylinder, and a fastener two is screwed onto the side away from the rotating block, with one end of the fastener two extending into the interior of the adjusting cylinder and pressing against the outer wall of the rotating block.

[0013] In addition, a preferred structure is that the outer wall of the column is provided with a pair of sliding grooves for limiting the connection bushing, the bushing is connected to a positioning rubber block, and a fastener three is screwed to the bottom side of the positioning rubber block. One end of the fastener three passes through the bushing and is pressed into contact with the outer wall of the column.

[0014] In addition, a preferred structure is that a second spring is provided in the groove, and the second spring is in compression contact with the bushing.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this invention, both the mounting platform and the lifting plate are equipped with adjustable cylinders that can be freely adjusted in height. The adjustable cylinders are also equipped with rotatable and independently adjustable positioning rubber blocks, which can be used to adapt to workpieces of different shapes and sizes without the need to replace the fixtures.

[0023] Reference Figure 1-4 A positioning fixture for processing motorcycle lights includes a mounting platform 1, a lifting plate 2 is provided in the middle of the mounting platform 1, the lifting plate 2 is driven to lift by a screw 3, and multiple sets of positioning posts 4 are provided on the workpiece clamping surfaces of the lifting plate 2 and the mounting platform 1, and positioning rubber blocks 5 are provided on the positioning posts 4 to position the workpiece.

[0024] Furthermore, a screw 7 is provided in the middle of the positioning column 4, and an adjusting cylinder 9 is screwed onto the screw 7. A rotating block 12 is installed on the top of the adjusting cylinder 9. A pair of positioning rubber blocks 5 are installed in the middle of the rotating block 12 by the column 13. One side of the positioning rubber block 5 is locked by fastener 3 11, and the positioning rubber block 5 is vertically limited and slidably installed on the column 13 by the slide groove 15.

[0025] The lead screw 3 is screwed to the mounting platform 1, and the bottom end of the lead screw 3 extends downward and is rotatably connected to the lifting plate 2. The lead screw 3 is used to control the lifting plate 2 to lift and press the workpiece.

[0026] When the adjusting cylinder 9 and the screw 7 rotate relative to each other, the adjusting cylinder 9 slides vertically inside the positioning column 4. By rotating the adjusting cylinder 9, the adjusting cylinder 9 and the screw 7 rotate spirally to achieve the height adjustment function of the adjusting cylinder 9.

[0027] A fastener 8 is screwed onto one side of the positioning post 4. One end of the fastener 8 extends into the interior of the positioning post 4 and presses against the outer wall of the adjusting cylinder 9. The fastener 8 is used to lock the adjusting cylinder 9 and prevent it from moving freely.

[0028] A spring element 6 is provided between the adjusting cylinder 9 and the positioning column 4. The spring element 6 lifts the adjusting cylinder 9, increasing the tightness of the connection between the adjusting cylinder 9 and the positioning column 4.

[0029] A rotating block 12 is rotatably mounted on the upper part of the adjusting cylinder 9, and a fastener 2 10 is screwed onto the side away from the rotating block 12. One end of the fastener 2 10 extends into the interior of the adjusting cylinder 9 and presses against the outer wall of the rotating block 12.

[0030] The outer wall of the column 13 is provided with a pair of sliding grooves 15 for limiting the connection of the bushing 14. The bushing 14 is connected to the outside of the positioning rubber block 5, and a fastener 3 11 is screwed to the bottom side of the positioning rubber block 5. One end of the fastener 3 11 passes through the bushing 14 and is pressed into contact with the outer wall of the column 13.

[0031] A second spring element 16 is provided inside the slide groove 15. The second spring element 16 is in contact with the bushing 14 by compression. The inner wall of the bushing 14 is provided with a protrusion that fits into the slide groove 15. The protrusion and the slide groove 15 are engaged, so that the bushing 14 is limited to be installed on the outer wall of the column 13. The second spring element 16 is provided to increase the tightness of the connection between the two.

[0032] In this embodiment, the lifting plate 2 and its corresponding clamps are driven to descend by rotating the lead screw 3, and the workpiece placed at the bottom of the mounting platform 1 is clamped.

[0033] The adjusting cylinder 9 on the rotating mounting platform 1 and the lifting plate 2 rotates relative to the screw 7 inside the positioning column 4, and adjusts the height to match the shape and size of the workpiece. At the same time, the fastener 11 can be loosened, and the two positioning rubber blocks 5 on the column 13 can be moved to create a height difference and form an L-shaped platform (groove) to better support the edges and corners of the headlight, effectively improving the contact surface and contact stability between the fixture and the workpiece.

[0034] At the same time, the fastener 10 can still be loosened, so that the rotating block 12 can be unlocked and rotated freely. The rotating block 12 drives the positioning rubber block 5 to rotate, thereby changing the angle of the positioning rubber block 5 and improving the positioning efficiency.

[0035] Fastener 8 is used to lock the adjusting cylinder 9;

[0036] Fastener 2 10 is used to lock the rotating block 12;

[0037] Fastener 311 is used to lock and position the rubber block 5.
