[0008] To achieve the above objectives, this utility model provides the following technical solution: a production fixture for car headlights, comprising a base, an adjustment groove at the top of the base, a bidirectional screw rotatably connected inside the adjustment groove, and two adjustment seats symmetrically threaded to the outside of the bidirectional screw. Both adjustment seats slide within the adjustment groove, and a clamping mechanism for clamping the car headlights is fixedly connected to the top of each adjustment seat. A motor is fixedly mounted on the side of the base, and the output end of the motor is fixedly connected to the side of the bidirectional screw. The two adjustment seats are fixedly mounted between themselves and the base, and also between themselves and the base. The system is equipped with three telescopic sleeves, all of which are fitted over the outside of the bidirectional screw. A discharge port is located at the bottom of the adjusting groove. Multiple support legs are fixedly connected to the bottom of the base, and support seats are fixedly connected to the bottom of the support legs. A collection box is placed on the support seat below the discharge port to facilitate the collection of waste material falling from the discharge port. This prevents waste material from falling into the threaded groove of the bidirectional screw. Waste material inside the adjusting groove can be discharged from the discharge port, avoiding interference with the normal transmission between the bidirectional screw and the adjusting seat, and ensuring normal sliding of the adjusting seat within the adjusting groove.

[0009] The present invention is further configured such that multiple support rods are fixedly connected inside the adjusting groove, the multiple support rods are slidably engaged with the two adjusting seats, the multiple support rods are located inside the three telescopic sleeves, and play a supporting role for the three telescopic sleeves, so as to avoid the telescopic sleeves from contacting the bidirectional screw and causing wear to the telescopic sleeves during the rotation of the bidirectional screw.

[0010] The present invention is further configured such that the clamping mechanism includes a vertical base, a rotating column rotatably connected to the vertical base, a rotating seat fixedly connected to the side end of the rotating column, a sliding groove provided on the side end of the rotating seat, two clamping plates slidably arranged inside the sliding groove, and a first electric cylinder fixedly connected to both ends of the rotating seat. The telescopic ends of the two first electric cylinders are respectively fixedly connected to the side ends of the two clamping plates, which facilitates clamping and fixing of the car headlights.

[0011] The present invention is further configured such that rubber pads are fixedly connected to the side ends of both clamping plates, which increases the softness of the clamping plate surface and protects the car headlights.

[0012] The present invention is further provided that the top end of the vertical base is threaded with a fixing screw that cooperates with the rotating column, so as to facilitate the fixing of the rotating column.

[0013] The present invention is further provided that a rotating handle is fixedly connected to the side end of the rotating column to facilitate the rotation of the rotating column.

[0014] The present invention is further configured such that two dust collection boxes are fixedly connected to the top of the base, and the two dust collection boxes are connected to each other through a connecting box. An air extraction pipe is fixedly connected to the side of the connecting box to facilitate the removal of dust.

[0015] The present invention is further configured such that two grooves are symmetrically arranged on the side end of the adjustment groove, and a pusher plate is slidably arranged inside the two grooves. The two pusher plates are fixedly connected by two connecting plates. A second electric cylinder is fixedly installed on the side end of the base. The telescopic end of the second electric cylinder is fixedly connected to the corresponding pusher plate. The gap between the bottom end of the adjustment seat and the bottom end of the adjustment groove is greater than the height of the pusher plate, which facilitates the cleaning of waste material inside the adjustment groove.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a production fixture for car headlights, which has the following advantages:

[0018] 1. Because the three telescopic sleeves are fitted on the outside of the bidirectional screw, waste material is prevented from falling into the threaded groove of the bidirectional screw. During the movement of the adjusting seat, the waste material inside the adjusting groove can be moved. The waste material inside the adjusting groove is discharged through the discharge port, preventing a large amount of waste material from accumulating inside the adjusting groove. This avoids waste material falling into the threaded groove of the bidirectional screw and prevents a large amount of waste material from accumulating inside the adjusting groove, thus avoiding affecting the normal transmission between the bidirectional screw and the adjusting seat and ensuring that the adjusting seat slides normally inside the adjusting groove.

[0019] 2. The exhaust fan of the air purification equipment connected to the outside of the exhaust pipe will work to remove the dust generated during the processing of the car headlights, preventing the dust from being scattered into the surrounding air, avoiding the impact on the surrounding environment, and preventing the dust from being inhaled by the workers and affecting their health.

[0020] 3. The second electric cylinder drives the two pusher plates and two connecting plates to move. When the pusher plates move towards the discharge port, they push the waste material inside the adjustment groove into the discharge port. When the pusher plates move into the groove, the base scrapes off the waste material at the top of the pusher plates, which facilitates the cleaning of the waste material inside the adjustment groove and prevents the waste material from accumulating inside the adjustment groove.

[0030] Please see Figures 1-5A car headlight production fixture includes a base 1, an adjustment groove 2 at the top of the base 1, a bidirectional screw 3 rotatably connected inside the adjustment groove 2, and two symmetrically threaded adjustment seats 4 on the outside of the bidirectional screw 3. Both adjustment seats 4 are slidably engaged with the adjustment groove 2, and a clamping mechanism for clamping the car headlight is fixedly connected to the top of each of the two adjustment seats 4. A motor 5 is fixedly mounted on the side of the base 1, and the output end of the motor 5 is fixedly connected to the side of the bidirectional screw 3. Telescopic sleeves 6 are fixedly connected between the two adjustment seats 4 and the base 1, and between the two adjustment seats 4. All three telescopic sleeves 6 are fitted onto the bidirectional screw 3. Externally, multiple support rods 8 are fixedly connected inside the adjusting groove 2. The multiple support rods 8 are slidably engaged with two adjusting seats 4. The multiple support rods 8 are located inside the three telescopic sleeves 6, which support the three telescopic sleeves 6 and prevent the telescopic sleeves 6 from contacting the bidirectional screw 3 and causing wear to the telescopic sleeves 6 during the rotation of the bidirectional screw 3. The bottom end of the adjusting groove 2 is provided with a discharge port 7. The bottom end of the base 1 is fixedly connected with multiple support legs 18. The bottom end of the multiple support legs 18 is fixedly connected with a support seat 19. A collection box 20 is placed on the support seat 19 below the discharge port 7 to facilitate the collection of waste materials falling from the discharge port 7.

[0031] Specifically, since the three telescopic sleeves 6 are fitted on the outside of the bidirectional screw 3, they prevent waste material from falling into the threaded groove of the bidirectional screw 3. During the movement of the adjusting seat 4, they can push the waste material inside the adjusting groove 2 to move. The waste material inside the adjusting groove 2 is discharged through the discharge port 7, which prevents a large amount of waste material from accumulating inside the adjusting groove 2. This avoids waste material falling into the threaded groove of the bidirectional screw 3 and prevents a large amount of waste material from accumulating inside the adjusting groove 2, thus avoiding affecting the normal transmission between the bidirectional screw 3 and the adjusting seat 4, and ensuring that the adjusting seat 4 slides normally inside the adjusting groove 2.

[0032] Please see Figure 1 The clamping mechanism includes a vertical base 9, a rotating column 10 rotatably connected to the vertical base 9, a rotating seat 11 fixedly connected to the side end of the rotating column 10, a sliding groove 12 provided on the side end of the rotating seat 11, two clamping plates 13 slidably arranged inside the sliding groove 12, a first electric cylinder 14 fixedly connected to both ends of the rotating seat 11, the telescopic ends of the two first electric cylinders 14 being fixedly connected to the side ends of the two clamping plates 13 respectively, facilitating the clamping and fixing of the car headlights, a rubber pad 15 fixedly connected to the side ends of the two clamping plates 13 to increase the softness of the surface of the clamping plates 13 and to protect the car headlights, a fixing screw 16 threadedly connected to the top of the vertical base 9 to cooperate with the rotating column 10, facilitating the fixing of the rotating column 10, and a rotating handle 17 fixedly connected to the side end of the rotating column 10, facilitating the rotation of the rotating column 10.

[0033] Specifically, the clamping plate 13 is moved by the first electric cylinder 14, and the car headlight is clamped and fixed by the clamping plate 13. The rotating column 10 is rotatably connected to the vertical column, which facilitates the rotation of the rotating seat 11 and the clamped car headlight, and facilitates the rotation of the car headlight. It also facilitates the rotation of the surface of the car headlight that needs to be processed to the upper side, and facilitates the processing of each side of the car headlight.

[0034] Please see Figure 1 Two dust collection boxes 25 are fixedly connected to the top of the base 1. The two dust collection boxes 25 are connected to each other through a connecting box 26. An air extraction pipe 27 is fixedly connected to the side of the connecting box 26 to facilitate the removal of dust.

[0035] Specifically, the exhaust fan of the air purification equipment connected to the external exhaust pipe 27 will remove the dust generated during the processing of the car headlights, preventing the dust from being scattered into the surrounding air, avoiding the impact on the surrounding environment, and preventing the dust from being inhaled by the staff and affecting their health.

[0036] Please see Figure 4 and Figure 5 Two grooves 21 are symmetrically arranged on the side end of the adjusting groove 2. Push plates 22 are slidably arranged inside the two grooves 21. The two push plates 22 are fixedly connected by two connecting plates 23. A second electric cylinder 24 is fixedly installed on the side end of the base 1. The telescopic end of the second electric cylinder 24 is fixedly connected to the corresponding push plate 22. The gap between the bottom end of the adjusting seat 4 and the bottom end of the adjusting groove 2 is greater than the height of the push plate 22, which facilitates the cleaning of waste inside the adjusting groove 2.

[0037] Specifically, the second electric cylinder 24 drives the two pusher plates 22 and the two connecting plates 23 to move. When the pusher plate 22 moves toward the discharge port 7, it pushes the waste inside the regulating groove 2 into the discharge port 7. When the pusher plate 22 moves toward the groove 21, the base 1 scrapes off the waste at the top of the pusher plate 22, which facilitates the cleaning of the waste inside the regulating groove 2 and prevents the waste from accumulating inside the regulating groove 2.

[0038] In summary, when using the overall equipment:

[0039] The motor 5 drives the bidirectional screw 3 to rotate, causing the two adjusting seats 4 to slide inside the adjusting groove 2, adjusting the distance between the two clamping mechanisms. After adjustment, the car headlight is placed in the middle of the four clamping plates 13. The four first electric cylinders 14 drive the four clamping plates 13 to move, clamping the car headlight. Then, the rotary handle 17, rotating column 10, rotating seat 11, and car headlight are rotated to rotate the surface to be processed to the upper side. Then, the fixing screw 16 is tightened to fix the rotating column 10, and then the car headlight is processed. During the processing, the exhaust fan of the air purification equipment connected to the outside of the exhaust pipe 27 works to remove the dust generated during the processing of the car headlights. The second electric cylinder 24 drives the two pusher plates 22 and the two connecting plates 23 to move. When the pusher plate 22 moves towards the discharge port 7, it pushes the waste material inside the adjustment groove 2 into the discharge port 7. When the pusher plate 22 moves into the groove 21, the base 1 scrapes off the waste material at the top of the pusher plate 22, causing the waste material inside the adjustment groove 2 to fall from the discharge port 7 and be collected by the collection box 20.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
