Detailed Implementation

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1-6 As shown, a clamping device for processing automotive headlights includes a base plate 1, side walls 2, a support frame 3, clamping arms 4, and bosses 5. The support frame 3 includes a telescopic rod 31, a buffer pad 32, and a handle 33. The side walls 2 are installed on both sides of the base plate 1. The bosses 5 are vertically installed on the base plate 1 and are evenly distributed on the base plate 1. The support frame 3 is installed in the bosses 5 and connected to the base plate 1. The clamping arms 4 are installed on the side walls 2 and are perpendicular to the installation direction of the support frame 3. The handle 33 is installed in the bosses 5 and the bottom of the handle 33 contacts the base plate 1. The telescopic rod 31 is installed on the top of the handle 33, and the buffer pad 32 is installed on the top of the telescopic rod 31.

[0025] The clamping device supports the weight of the headlight by using the support frame 3 and clamps the headlight onto the support frame 3 using the clamping arm 4. The boss 5 provides positioning for the installation of the support frame 3 and improves the rigidity of the support frame 3. When different types of headlights are placed on the support frame 3, due to gravity, the support frame 3 sinks a certain distance on the base plate 1. The support frame 3 and the unsupported support frame 3 clamp the headlight. At this time, the clamping arm 4 is raised to further fix the headlight, achieving complete fixation of the headlight. The buffer pad 32 uses elastic material to contact the headlight to avoid rigid friction damaging the headlight. The telescopic rod 31 is used to install the buffer pad 32. The thickness of the rod handle 33 is much greater than the thickness of the telescopic rod 31 to support the buffer pad 32 more stably.

[0026] See Figures 3-5 As shown, the telescopic rod 31 includes a first spring 311 and a ball joint 312. The first spring 311 is disposed on the outside of the telescopic rod 31. One end of the first spring 311 is connected to the boss 5, and the other end is connected to the buffer pad 32. The ball joint 312 is installed on the top of the telescopic rod 31.

[0027] The first spring 311 is used to reset the support frame 3 after the headlight is removed, and the ball joint 312 provides space for the buffer pad 32 to rotate, so that the buffer pad 32 always supports the headlight with the maximum contact area.

[0028] See Figures 3-6 As shown, the buffer pad 32 includes a housing 321, a locking platform 322, a first turntable 323, a second turntable 324, and a second spring 325. The housing 321 is fixedly connected to the bottom of the buffer pad 32. The locking platform 322 is mounted on the telescopic rod 31 and fixed to the telescopic rod 31. The first turntable 323 is distributed in a ring on the lower surface of the buffer pad 32. The second turntable 324 is distributed in a ring on the locking platform 322. The number and position of the second turntable 324 correspond to the number and position of the first turntable 323. The second spring 325 is disposed between the first turntable 323 and the second turntable 324.

[0029] The mounting plate 322 moves together with the telescopic rod 31. The size of the sleeve 321 corresponds to that of the ball joint 312. When the headlight presses against the buffer pad 32, the buffer pad 32 rotates at various angles from the direction parallel to the ground. After the headlight is removed, the buffer pad 32 returns to the state of being parallel to the ground under the action of the second spring 325.

[0030] See Figures 2-3 As shown, a positioning strip 331 is provided on the handle 33. The positioning strip 331 surrounds the handle 33. The positioning strip 34 is used to assist the handle 33 in being installed on the boss 5. The four positioning strips 34 increase the contact area between the handle 33 and the boss 5, reducing the possibility of the handle 33 rotating in the boss 5.

[0031] See Figures 1-4 As shown, the clamping arm 4 includes an airbag 41, a push rod 42, a fixing frame 43, and a flange 44. The flange 44 is mounted on the side wall 2. One end of the airbag 41 is mounted on the flange 44, and the other end is fixedly connected to the push rod 42. The fixing frame 43 is fixedly connected to the flange 44 and slidably connected to the push rod 42.

[0032] The clamping arm 4 uses the airbag 41 to pressurize and assist in fixing the side of the headlight, avoiding damage to the headlight by rigid mechanical movement. The fixing bracket 43 is used to ensure that the push rod 42 always moves in a direction perpendicular to the support bracket 3.

[0033] See Figure 4 As shown, the airbag 41 includes a waist ring 411, an air tube 412, and a pressurizer 413. The waist ring 411 is installed between two airbags 41. The air tube 412 passes through the side wall 2. One end of the air tube 412 is connected to the outer surface of the airbag 41, and the other end is connected to the pressurizer 413. The pressurizer 413 is placed on the ground.

[0034] The waist ring 411 is used to separate the two airbags 41 to prevent the two airbags 41 from forming a single airbag 41 after being filled with air pressure. Pressurizing a single airbag 41 separately also facilitates the control of the push rod 42's advance distance. The air tube 412 is used to transmit the air pressure in the pressurizer 413 into the airbag 41.

[0035] See Figure 2 As shown, the boss 5 includes a groove 51 and a positioning groove 52. The groove 51 is disposed on the base plate 1 and located at the center of the boss 5, and the positioning groove 52 is distributed around the groove 51.

[0036] The groove 51 is embedded in the base plate 1 to strengthen the fixation of the boss 5 on the support frame 3 and prevent the support frame 3 from rotating. The positioning groove 52 further strengthens the fixation of the boss 5 on the support frame 3 and prevents the groove 51 from aging and failing to completely fix the support frame 3 after long-term use of the device.

[0037] See Figures 1-2 As shown, a mounting groove 6 is provided on the side wall 2, and a screw 7 is provided on the inner side of the side wall 2 and passes through the bottom of the clamping arm 4 and the side wall 2 to be rotatably connected to the nut 8.

[0038] Screws 7 and nuts 8 secure the flange 44 on the clamping arm 4 to the mounting groove 6. The mounting groove 6 is designed to be long enough to adjust the distance of the clamping arm 4 on the side wall 2. The distance is adjusted manually to ensure that the clamping arm 4 can always hold the side of the headlight at the best angle.

[0039] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
