The device includes a base plate and an adjusting rod mounted on the upper side of the base plate. A support device is provided on the upper side of the base plate, comprising suction cups, a support base, a strut, and a telescopic rod. Multiple sets of suction cups are evenly distributed on the upper side of the support base. A rotation damper is provided between the support base and the strut. A fixing screw is provided between the strut and the telescopic rod. The adjusting rod is located in the middle of the upper side of the base plate, and multiple sets of the support device are evenly distributed on the outer side of the adjusting rod. This utility model uses a support base to install multiple sets of suction cups to fix the inner lens.

[0004] The aforementioned patent also has the following defects: such as the reliability of the suction cup fixation. Vibration will occur during the processing, and the suction cup is prone to "creep" or instantaneous loss of seal under vibration, which will cause the lens to shift or even fall off, seriously affecting the processing accuracy and safety. Therefore, a fixing device for processing automotive high beam inner lens is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fixing device for processing automotive high beam inner lenses, which has advantages such as good fixing effect and solves the problem that vibrations occur during processing, and the suction cup is prone to loosening under vibration, leading to lens displacement or even detachment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fixing device for processing automotive high beam inner lens, comprising a support assembly and a fixing structure one and a fixing structure two disposed on the support assembly;

[0007] The support assembly includes a fixing frame, and two inclined abutment plates are fixed on the right side of the fixing frame. Fixing structure one is disposed on the fixing frame, and fixing structure two is disposed on the abutment plates.

[0008] The fixing structure consists of a piston and abutment, which cooperate with each other, and a clamping plate for fixing to the fixing frame is provided on the side of the piston away from the abutment.

[0009] The second fixing structure includes a screw threaded through the inside of the abutment plate, with a knob and an abutment pad fixed at both ends of the screw.

[0010] Furthermore, the fixing frame consists of two horizontal plates distributed vertically and a vertical plate welded between the two horizontal plates. Both abutment plates are welded to the right side of the two horizontal plates, and the left side of both horizontal plates is provided with fixing grooves that engage with the locking plate.

[0011] Furthermore, the two abutment plates are symmetrically arranged, and the interior of the vertical plate has a through hole for mounting a fixing structure. The lower surface of the bottom horizontal plate is bolted with a mounting bracket.

[0012] Furthermore, the piston component includes a sleeve fixed inside the through hole. A guide rod and a piston are disposed inside the sleeve. One end of the guide rod extends to the outside of the sleeve, and an abutment cover is fixed to the end of the guide rod. A buffer pad that abuts against the lens is fixed to the side of the abutment cover away from the guide rod.

[0013] Furthermore, the sleeve is hollow inside, the guide rod is a hollow shaft and the guide rod is connected to the abutment cover, a second return spring is installed between the guide rod and the sleeve, and a limiting frame for limiting the guide rod is fixed inside the sleeve.

[0014] Furthermore, a stopper rod extending to the outside of the sleeve is fixed on the side of the piston away from the guide rod, and the other end of the stopper rod is rotatably connected to the outer wall of the clamping plate. A first return spring surrounding the outside of the stopper rod is rotatably installed between the sleeve and the clamping plate.

[0015] Furthermore, there are two fixing structures, which are symmetrically distributed on the two abutment plates and the two abutment pads are arranged opposite each other.

[0016] Compared with the prior art, this utility model provides a fixing device for processing automotive high beam inner lenses, which has the following beneficial effects:

Detailed Implementation

[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 protection scope of the present utility model.

[0025] Please see Figures 1 to 4 This embodiment of a fixing device for processing automotive high beam inner lenses includes a support assembly and fixing structure 3 and fixing structure 4 disposed on the support assembly. Specifically, the support assembly includes a fixing frame 1, and two inclined abutment plates 2 are fixed on the right side of the fixing frame 1. Fixing structure 3 is disposed on the fixing frame 1, and fixing structure 4 is disposed on the abutment plates 2. The fixing frame 1 consists of two horizontal plates distributed vertically and a vertical plate welded between the two horizontal plates. The two abutment plates 2 are both welded to the right side of the two horizontal plates.

[0026] The two abutment plates 2 are symmetrically arranged. The interior of the vertical plate has through holes 12 for mounting a fixing structure 3. The lower surface of the bottom horizontal plate is bolted with a mounting bracket 11. The mounting bracket 11 can be used to support and fix the equipment. Anti-slip pads are fixed on opposite sides of the two abutment plates 2.

[0027] To secure the lens, the fixing structure 3 consists of a piston and a stop member. The piston and the stop member work together, and a locking plate 37, which is fixed to the fixing bracket 1, is provided on the side of the piston away from the stop member. Specifically, a fixing groove 13 is provided on the left side of each of the two horizontal plates to engage with the locking plate 37. The insertion of the locking plate 37 into the steel fixing groove 13 forms a physical self-locking mechanism, completely avoiding the risk of loosening caused by spring rebound. Specifically, the piston includes a sleeve 31 fixed inside the through hole 12. A guide rod 32 and a piston 35 are provided inside the sleeve 31. One end of the guide rod 32 extends to the outside of the sleeve 31, and a stop cover 33 is fixed to the end of the guide rod 32. A buffer pad 34, which abuts against the lens, is fixed to the side of the stop cover 33 away from the guide rod 32. The buffer pad 34 is made of silicone or rubber with a Shore hardness of A50-60 and is in direct contact with the lens surface. Its elastic deformation can absorb the energy of processing vibration, reducing the stress on the lens surface to below the yield strength of materials such as PC / PMMA, thus avoiding microcracks or silver streaks.

[0028] It should be noted that the sleeve 31 is hollow inside, the guide rod 32 is a hollow shaft, and the guide rod 32 is connected to the abutment cover 33. A second return spring 39 is installed between the guide rod 32 and the sleeve 31. A limiting bracket 310 for limiting the guide rod 32 is fixed inside the sleeve 31. A contact rod is fixed to one end of the guide rod 32 near the piston 35.

[0029] For easy disassembly, a stopper rod 36 extending to the outside of the sleeve 31 is fixed to the side of the piston 35 away from the guide rod 32. The other end of the stopper rod 36 is rotatably connected to the outer wall of the clamping plate 37. A first return spring 38 is rotatably installed between the sleeve 31 and the clamping plate 37, surrounding the stopper rod 36. Pressing the guide rod 32 will trigger the clamping plate 37 to insert into the fixing groove 13, achieving instantaneous locking of the axial clamping force; pulling out the clamping plate 37 will unlock it, without the need for additional tools. Clamping is completed in a single action, greatly shortening the clamping time.

[0030] To further secure the lens, fixing structure two 4 includes a screw 41 threaded through the interior of the abutment plate 2. A knob 42 and an abutment pad 43 are fixed to both ends of the screw 41, respectively. The abutment pad 43 is made of rubber or polyurethane to distribute pressure and prevent scratches on the lens edge. There are two fixing structures two 4, symmetrically distributed on the two abutment plates 2, with the two abutment pads 43 facing each other. It should be noted that the two screws 41 are mirror-symmetrical on the inclined abutment plates 2, pushing the opposing abutment pads 43 to simultaneously horizontally clamp the two edges of the lens, cooperating with the axial pressing of fixing structure one 3 to form a stable triangular constraint of two clamps and one press. Furthermore, the threaded engagement between the screw 41 and the abutment plate 2 has frictional self-locking properties.

[0031] The working principle of the above embodiments is as follows:

[0032] In the initial state, the guide rod 32 of the fixed structure 1 3 is in the extended state under the action of the second return spring 39, the buffer pad 34 is away from the lens, and the screw 41 of the fixed structure 2 4 is retracted by rotating the knob 42, so that the abutment pad 43 is away from the lens mounting position.

[0033] When fixing, the lens is placed vertically between the upper and lower horizontal plates of the fixing frame 1, with its edge close to the two inclined abutment plates 2 on the right side. The lens first fits against the abutment cover 33, and then the lens pushes the guide rod 32 to retract into the sleeve 31, compressing the second return spring 39. The guide rod 32 pushes the piston 35 to move backward, driving the plug rod 36 to extend. The clamping plate 37 is rotated so that the clamping plate 37 is inserted into the fixing groove 13 of the horizontal plate, thus achieving the initial fixing of the lens.

[0034] Then, rotating the two knobs 42 pushes the screw 41 inward, and the symmetrically arranged abutment pads 43 horizontally clamp the non-optical area of ​​the lens edge from both sides, providing further fixation.

[0035] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0036] Any method that can achieve its beneficial effects can be implemented.
