Description

Technical Field

[0001] This utility model relates to the field of automotive lamp sample processing technology, and in particular to a fixture adjustment device for auxiliary machine tool equipment for processing automotive lamp samples. Background Technology

[0002] In the production of automotive headlight prototypes, machine tools (such as 3-axis CNC milling machines) have become the mainstream processing equipment due to their controllable cost and ease of operation. Existing machine tools can only perform vertical downward cutting operations, which can meet the processing needs of most conventional planes and holes in automotive headlight prototypes.

[0003] However, some automotive headlight prototypes typically have features such as assembly structures on their side areas. Due to the limitations of the vertical machining method of machine tools, the machining head of the machine tool cannot directly reach the area to be machined at that angle of the automotive headlight prototype, thus hindering the machining of the automotive headlight prototype.

[0004] To facilitate the processing of these automotive headlight prototypes, existing manufacturers typically use manual hand-held clamps or temporary shims to adjust the angle of the prototypes before machine tools can process them. However, these existing clamping and shim-raising methods have the following drawbacks:

[0005] 1) Temporarily raising the headlight sample can easily lead to deviations in the positioning accuracy of the headlight sample, resulting in out-of-tolerance structural dimensions after processing;

[0006] 2) If the machine tool is replaced with a 5-axis CNC or other multi-axis machine tool, the purchase cost of the machine tool will increase, and the debugging cycle of multi-axis equipment is long, which is not suitable for the rapid processing needs of small batches of automotive lamp prototypes.

[0007] 3) When using manual hand-held fixtures, the fixtures are usually fixed structures and cannot be flexibly adjusted according to the processing requirements of the car light sample. If the car light sample needs to be processed at multiple different angle positions, the fixtures need to be frequently disassembled or reinstalled. This is not only cumbersome, but also prone to errors due to repeated positioning, affecting the processing accuracy. Utility Model Content

Detailed Implementation

[0033] The present invention will now be described in detail with reference to the accompanying drawings, which form part of this specification. The principles of the present invention will be illustrated through embodiments, and other aspects, features, and advantages of the present invention will become apparent from this detailed description. In the accompanying drawings, the same or similar parts in different figures are indicated by the same reference numerals.

[0034] like Figures 1-4 As shown, this utility model provides a fixture adjustment device for machining automotive lamp samples on a machine tool. The fixture adjustment device includes a base plate 1 and a fixture positioning structure 2 and an angle adjustment structure 3 fixed to the base plate 1. The fixture positioning structure 2 is rotatably mounted above the angle adjustment structure 3. The fixture positioning structure 2 includes a fixture rotating body 21 and a clamping and positioning mechanism 22 for clamping the automotive lamp sample. The clamping and positioning mechanism 22 is mounted on the fixture rotating body 21, and guide rails 211 are fixed on both sides of the fixture rotating body 21. The angle adjustment structure 3 includes a fixture adjustment mechanism. The fixture adjustment seat 31 and the locking adjustment handle 32 are mounted on one side wall of the fixture adjustment seat 31. The fixture adjustment seat 31 is fixed above the base plate 1. The top of the fixture adjustment seat 31 is provided with a slide groove 311 that cooperates with the guide rail 211 of the fixture rotating body 21 and allows the fixture rotating body 21 to rotate. An angle gauge 312 is provided on the outer wall of the slide groove 311 of the fixture adjustment seat 31. The guide rail 211 of the fixture rotating body 21 is slidably set on the slide groove 311 of the fixture rotating body 21 to realize the rotational connection between the fixture rotating body 21 and the fixture adjustment seat 31. Thus, the fixture positioning structure 2 can be rotatably mounted on the angle adjustment structure 3. Specifically, the scale range of the angle gauge 312 is 0-90°, and the minimum scale value is 1°, which makes it easy for the operator to read the angle adjusted by the fixture rotating body 21.

[0035] The clamping positioning structure 2 of this utility model clamps the car lamp sample through a clamping positioning mechanism 22. The clamping positioning mechanism 22 is directly mounted on the clamping rotating body 21. During angle adjustment, the clamping rotating body 21 always clamps the car lamp sample to prevent the car lamp sample from shifting during adjustment. The clamping positioning structure 2 cooperates with the guide rail 211 of the clamping adjusting seat 31 and the slide groove 311 of the clamping adjusting seat 31 so that the clamping rotating body 21 and the car lamp sample clamped thereon can slide on the clamping adjusting seat 31, so that the clamping rotating body 21 and the car lamp sample clamped thereon can rotate stably, and the clamping rotating body 21 can be adjusted within the tilt angle range of the angle scale 312. In addition to adjusting the angle, this utility model also provides an angle gauge 312 on the outer wall of the slide groove 311. The operator can adjust the angle of the fixture rotating body 21 and the car lamp sample clamped on it (such as any angle within the range of 0-90°) according to the processing requirements, effectively avoiding errors and ensuring angle consistency. The fixture adjustment device set in this utility model facilitates the processing of car lamp samples by machine tools. It is installed on the machine tool through the base plate 1, so that the car lamp sample waiting to be processed can be adjusted at multiple angles during the processing without changing the fixture. It is particularly suitable for processing the side edges and corners of the workpiece on the milling machine, with wide applicability and improved processing quality of car lamp samples.

[0036] In this embodiment of the utility model, the base plate 1 has mounting holes 11 and connecting parts that cooperate with the mounting holes 11 on both sides. The mounting holes 11 of the base plate 1 are connected to the worktable of the machine tool through the connecting parts.

[0037] Preferably, the mounting hole 11 is an elongated hole, and the connecting piece is preferably a bolt. By cooperating with the mounting hole 11 of the base plate 1 and the connecting piece, the entire fixture adjustment device can be fixed at a designated position on the machine tool worktable, ensuring that the base plate 1 fits tightly with the machine tool worktable without loosening. The mounting hole 11 is provided with an elongated hole so that the base plate 1 can be fixed at different positions on the machine tool equipment.

[0038] In a specific implementation of this utility model embodiment, a plurality of positioning holes 212 are provided on the clamp rotating body 21, and the plurality of positioning holes 212 are distributed at intervals on one side of the guide rail 211. The clamp adjusting seat 31 is provided with pin holes 313 corresponding to the plurality of positioning holes 212 of the clamp rotating body 21. The other side wall of the clamp adjusting seat 31 is provided with a positioning pin 33 for limiting and fixing the clamp rotating body 21. The positioning pin 33 is inserted into the pin hole 313 of the clamp adjusting seat 31 and the positioning hole 212 of the clamp rotating body 21 to fix the clamp rotating body 21 and the clamp adjusting seat 31.

[0039] like Figures 5-7As shown, the locking adjustment handle 32 of this utility model includes a rotating handle 321, a connecting screw 322, and a clamping block 323 that cooperates with the connecting screw 322. The side wall of the clamp adjustment seat 31 is provided with a second threaded hole 314 that cooperates with the connecting screw 322. The screw end of the connecting screw 322 passes through the second threaded hole 314 and the clamping block 323 in sequence through the side wall of the clamp adjustment seat 31. The end of the connecting screw 322 away from the screw is fixed to the rotating handle 321. The connecting screw 322 passes through the side wall of the clamp adjustment seat 31 and abuts against the outer surface of the guide rail 211 of the clamp rotating body 21 through the clamping block 323 to lock and fix the clamp rotating body 21 to the outer periphery of the clamp adjustment seat 31. In specific implementation, a first threaded hole is provided in the middle of the clamping block 323, and a groove 3231 is provided on the edge of the clamping block 323 to mate with the outer surface of the guide rail 211 of the clamping rotating body 21. The clamping block 323 is threadedly connected to the connecting screw 322 through the first threaded hole in the middle, and the clamping block 323 abuts against the outer surface of the guide rail 211 of the clamping rotating body 21 through the groove 3231. The rotating handle 321 of this utility model is made of plastic. By rotating the rotating handle 321 of the locking adjustment handle 32, the connecting screw 322 moves axially along the second threaded hole 314 of the clamping adjustment seat 31, so that the groove 3231 of the clamping block 323 is locked or separated from the outer wall of the guide rail 211 of the clamping rotating body 21. Through the tightening operation of the connecting screw 322 and the clamping block 323, the clamping rotating body 21 and the adjusting clamping seat 31 are locked and fixed, which is convenient to operate.

[0040] In other embodiments, anti-slip textures may be provided on the surface of the handle.

[0041] In this embodiment of the utility model, the slide groove 311 of the clamp adjustment seat 31 is set as an arc-shaped structure, the guide rail 211 of the clamp rotating body 21 is set as a semi-circular structure, the arc of the clamp rotating body 21 is consistent with the arc of the slide groove 311, the angle ruler 312 is set on the side surface of the slide groove 311, and the side surface of the guide rail 211 is provided with an angle pointer 214. This invention sets the guide rail 211 of the clamp rotating body 21 into a semi-circular structure that cooperates with the slide groove 311 to prevent the clamp rotating body 21 from falling off during rotation, and further ensures the stability of the angle adjustment process of the clamp rotating body 21. An inclination pointer 214 is set to indicate the rotation angle, which makes it convenient for the operator to adjust the rotation angle of the clamp rotating body 21. In specific implementation, the clamp rotating body 21 of this invention has a U-shaped structure with the opening facing upward. The two sides of the clamp rotating body 21 are fixed with semi-circular guide rails 211. The clamp rotating body 21 and the guide rails 211 are integrally formed of aluminum alloy. The use of aluminum alloy material can reduce weight and ensure strength.

[0042] In its specific implementation, the clamping and positioning mechanism 22 includes a lead screw 221, a movable slider 222, and a slide rail 223. A groove 213 is formed in the middle of the clamping rotating body 21. One end of the lead screw 221 passes through one side of the clamping rotating body 21 to the other side. The upper end of the movable slider 222 has a third threaded hole, and the lower end of the movable slider 222 has a sliding groove that cooperates with the slide rail 223. The lead screw 221 passes through the third threaded hole at the upper end of the movable slider 222 to... A threaded connection is established between the lead screw 221 and the movable slider 222. A slide rail 223 is parallel to the lead screw 221 and located in the groove 213 of the clamping rotating body 21. The slide rail 223 also passes through the sliding groove at the lower end of the movable slider 222 and connects to it. A limit stop 215 is fixed to one side of the clamping rotating body 21. A fixed area for clamping the automotive lamp sample to be processed is formed between the movable slider 222 and the end of the clamping rotating body 21 away from the lead screw 221. In specific implementation, the limit stop 215 and the movable slider 222 are mirror images of each other. When the movable slider 222 moves under the rotation of the lead screw 221, it slides along the axis of the slide rail 223 during movement. By setting the slide rail 223, the stability of the movable slider 222 during movement is improved.

[0043] In this invention, a movable clamping plate 224 is fixed to one side of the movable slider 222, and a fixing plate 216 is fixed to the opposite side of the limiting block 215 and the movable slider 222. The movable clamping plate 224 and the fixing plate 216 are arranged opposite to each other. A fixing area for clamping the vehicle headlight sample is formed between the movable clamping plate 224 of the movable slider 222 and the fixing plate 216 of the limiting block 215.

[0044] The operation process for clamping and positioning the vehicle lamp sample to be processed according to this utility model is as follows:

[0045] Rotating the adjusting handle 225 causes the lead screw 221 to rotate accordingly. When the lead screw 221 rotates, the movable slider 222 is displaced under the rotation of the lead screw 221 and moves toward the side of the fixed clamping end, changing the size of the fixed area. As the movable slider 222 moves, the movable clamping plate 224 on the movable slider 222 approaches the fixed plate 216 on the limit stop 215, so that the movable clamping plate 224 and the fixed plate 216 can clamp and fix the car lamp sample to be processed, realize the processing positioning of the car lamp sample, improve the stability of the processing of the car lamp sample, and the overall structure is simple.

[0046] In a specific implementation, an adjusting handle 225 is fixed at the other end of the lead screw 221. The adjusting handle 225 includes a connecting post 2251, a handle rod 2252, and a stop 2253. The connecting post 2251 is fixed to the other end of the lead screw 221. The handle rod 2252 passes through the inner diameter of the connecting post 2251 and is connected to the connecting post 2251. The stop 2253 is fixed at both ends of the handle rod 2252.

[0047] The operation process for adjusting the angle of the vehicle headlight sample to be processed according to this utility model is as follows:

[0048] First, rotate the rotating handle 321 of the locking adjustment handle 32 to make the connecting screw 322 move axially along the second threaded hole 314 of the clamp adjustment seat 31, and the slot 3231 of the clamping block 323 on the connecting screw 322 moves away from the outer wall of the guide rail 211 of the clamp rotating body 21.

[0049] Next, when the slot 3231 of the clamping block 323 no longer holds the guide rail 211 of the clamp rotating body 21, the positioning pin 33 on the other side wall of the clamp adjusting seat 31 is pulled out, so that the positioning pin 33 does not limit or fix the clamp rotating body 21.

[0050] Then, push the jig rotator 21 so that the guide rail 211 of the jig rotator 21 slides along the slide groove 311 of the jig adjustment seat 31, thereby realizing the angle adjustment of the jig rotator 21, and thus the angle adjustment of the car lamp sample clamped on the jig rotator 21. During the sliding process, observe the angle ruler 312. When the tilt pointer 214 of the guide rail 211 points to the position of the angle ruler 312, which is the required angle (such as 30° or 45°), stop pushing.

[0051] Finally, insert the positioning pin 33 into the pin hole 313 of the clamp adjustment seat 31 and the positioning hole 212 of the clamp rotating body 21, and rotate the rotating handle 321 of the locking adjustment handle 32 so that the slot 3231 of the clamping block 323 locks the guide rail 211 of the clamp rotating body 21, preventing the guide rail 211 of the clamp rotating body 21 from sliding on the slide groove 311 of the clamp adjustment seat 31, thereby fixing the angle of the clamp rotating body 21.

[0052] During the angle adjustment process of the car light sample to be processed, it is only necessary to push the clamp rotating body 21 so that the guide rail 211 on it slides along the slide groove 311 of the clamp adjustment seat 31. After the angle meets the requirements, the angle can be fixed by locking the adjustment handle 32 and the positioning pin 33, which greatly simplifies the operation steps, reduces the adjustment time, and improves the processing efficiency.

[0053] The operation process of this utility model's clamp adjustment device for assisting machine tool equipment in processing automotive lamp samples is as follows:

[0054] Step 1) Fixture adjustment device installation: Through the mounting holes 11 of the base plate 1, use bolts to fix the entire fixture adjustment device to the designated position on the machine tool worktable of the machine tool equipment, ensuring that the base plate 1 fits tightly with the machine tool worktable without any looseness;

[0055] Step 2) Workpiece positioning and clamping: Place the car light sample to be processed between the movable clamping plate 224 and the fixed plate 216 of the limiting block 215, rotate the adjusting handle 225 to make the movable slider 222 move on the lead screw 221. During the movement, the movable slider 222 will drive the movable clamping plate 224 to move towards the fixed plate 216 of the limiting block 215 until the movable clamping plate 224 and the fixed plate 216 clamp the car light sample.

[0056] Step 3) Workpiece angle adjustment: According to the processing requirements, rotate the rotating handle 321 of the locking adjustment handle 32 so that the slot 3231 of the clamping block 323 on the connecting screw 322 is away from the outer wall of the guide rail 211 of the fixture rotating body 21. Pull out the positioning pin 33 on the other side wall of the fixture adjustment seat 31 and push the fixture rotating body 21 so that the guide rail 211 of the fixture rotating body 21 slides along the slide groove 311 of the fixture adjustment seat 31. During the rotation of the fixture rotating body 21, observe the angle ruler 312. When the angle reaches the angle required for processing the car headlight sample, stop pushing.

[0057] Step 4) Angle fixing: Insert the positioning pin 33 into the pin hole 313 of the clamp adjustment seat 31 and the positioning hole 212 of the clamp rotating body 21, rotate the locking adjustment handle 32, so that the slot 3231 of the clamping block 323 on the connecting screw 322 is locked with the outer wall of the guide rail 211 until the guide rail 211 on the clamp rotating body 21 can no longer slide in the slide groove 311 on the clamp adjustment seat 31, and the angle fixing is completed;

[0058] Step 5) Machining and Angle Adjustment: Start the machine tool to process the headlight sample. If the angle needs to be adjusted after a single machining operation, repeat steps 3-4). There is no need to disassemble the headlight sample until all machining processes are completed.

[0059] Step 6) Remove the workpiece: After processing is completed, turn off the machine tool, turn the adjusting handle 225 so that the moving clamp 224 and the fixed plate 216 no longer clamp the car light sample, remove the car light sample, and complete the processing flow.

[0060] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
