Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a multi-angle adjustable car door sill anti-scratch repair clamp. Background Technology

[0002] Car door sill plates, also known as door sill strips or welcome pedals, are horizontal structural components located directly below the car door and at the bottom edge of the vehicle body. They connect the door to the bottom of the body and serve both decorative and protective functions. Their main function is to protect against friction from shoes when getting in and out of the car and scratches from carrying items, reducing paint damage. Door sill plates made of high-strength steel or aluminum alloy can also disperse impact force in side collisions, protecting the integrity of the vehicle body structure. These door sill plates are often covered with stainless steel trim or plastic parts with the vehicle model logo, thereby enhancing the vehicle's aesthetics and brand recognition. During the repair or assembly of door sill plates, clamps are needed to hold them in place to maintain their stability during the repair process.

[0003] When repairing existing door sill plates using clamps, the clamps are typically equipped with electric lifting rods and positioning suction cups to adsorb and fix the door sill plate material. Combined with hydraulic push rods, the clamping structure clamps and fixes the plate material. Then, with the lifting structure, it is raised for processing and repair.

[0004] While the aforementioned existing technologies have significant beneficial effects, they still have shortcomings:

[0005] The aforementioned clamps use a combination of clamping and adsorption to hold and fix the door sill plate, thus avoiding the risk of detachment caused by the loosening of traditional suction cups. However, after clamping and fixing the door sill plate, the combination of adsorption and clamping makes it difficult to adjust the angle of the door sill plate, which is inconvenient during repair work. At the same time, the clamping structures on both sides are mostly made of rigid materials, which can easily over-clamp the edges of the door sill plate, resulting in deformation or scratches, affecting normal repair work and causing losses. Therefore, a multi-angle adjustable anti-scratch repair clamp for automotive door sill plates is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a multi-angle adjustable car door sill plate anti-scratch repair clamp. By using a horizontally elongated clamping frame, and with multiple sets of suction cups evenly arranged on the clamping frame, the clamping frame adsorbs the car door sill plate at equal intervals, forming an adsorption fixation. This flexible adsorption clamping process maintains adsorption on the center of the door sill plate and fits and limits the sides, avoiding scratches to the plate itself during the clamping process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle adjustable car door sill anti-scratch repair clamp, comprising an adjusting bracket, a clamping mechanism fixed at the bottom end of the adjusting bracket, the clamping mechanism comprising a positioning frame, electric telescopic rods connected to both ends of the top surface of the positioning frame, a clamping frame connected to the end of the electric telescopic rods, circular holes on both sides of the clamping frame, a limiting post fitted inside the inner wall of the circular hole, a buffer post fitted inside the limiting post, a rubber pad fixed at the top of the buffer post, a high-pressure spring connected to the bottom end of the buffer post, a suction cup post fixed at the center of the top surface of the clamping frame, a suction cup connected to one end of the suction cup post, an air tube frame connected to the other end of the suction cup post, and a connecting tube connected to one end of the air tube frame.

[0008] Preferably, the air tube frame is embedded and fixed inside the clamping frame, and the suction cup is connected to the air tube frame through a suction cup post.

[0009] Preferably, the suction cups and suction cup posts are arranged equidistantly along the top surface of the clamping frame, and the suction cup posts are fixed to the clamping frame around their perimeter.

[0010] Preferably, the clamping frame is telescopically connected to the positioning frame via electric telescopic rods at both ends, and the positioning frame is fixedly connected to the adjusting bracket.

[0011] Preferably, the limiting piles are symmetrically distributed along both sides of the top surface of the positioning frame, and the buffer piles form an elastic structure with the limiting piles through a high-pressure spring.

[0012] Preferably, the adjusting bracket includes a tripod, with a rotating shaft connected to the center of the tripod. A torque motor is connected to one end of the rotating shaft. A support rod is fixed to the top surface of the rotating shaft. A turntable frame is fixed to the top of the support rod. A circular disc frame is connected to the top surface of the turntable frame. A servo motor is fixed to the center of the circular disc frame. Threaded holes are provided around the circular disc frame.

[0013] Preferably, the tripod is rotatably coupled with the support rod via a rotating shaft and a torque motor, and the support rod forms a rotating structure with the disc frame via a turntable frame and a disc frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model employs a horizontally elongated clamping frame, along with multiple sets of suction cups evenly arranged on the clamping frame, to equidistantly adsorb the car door sill plate. After adsorption, the suction cups can retract as a whole, causing the two sides of the door sill plate to fit against the buffer posts. The buffer posts, in conjunction with the elastic structure and rubber pads, can stably fit against the sill plate's inverted surface, forming an adsorption fixation. This flexible adsorption clamping process maintains adsorption at the center of the door sill plate and limits the fit on both sides, avoiding scratches to the plate itself during clamping, improving the safety of repair processing and reducing losses.

[0016] 2. The rotating shaft at the bottom of the clamp support rod can be driven by a torque motor at one end, so that the positioning frame fixed by the tripod can be rotated and adjusted as a whole. Through the cooperation of the double-end rotating structure, the clamp can be adjusted in multiple angles during operation, which facilitates the repair of car door sills.

[0017] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures pointed out in the description, claims, and drawings. Attached Figure Description

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This embodiment of a multi-angle adjustable car door sill anti-scratch repair fixture includes an adjustment bracket 1. A clamping mechanism 2 is fixed at the bottom end of the adjustment bracket 1. The adjustment bracket 1 includes a tripod 101. A rotating shaft 102 is connected to the center of the tripod 101. A torque motor 103 is axially connected to one end of the rotating shaft 102. A support rod 104 is fixed to the top surface of the rotating shaft 102. A turntable frame 105 is fixed to the top end of the support rod 104. A disc frame 106 is connected to the top surface of the turntable frame 105. A servo motor 107 is fixed to the center of the disc frame 106. Threaded holes 108 are opened around the disc frame 106.

[0025] like Figure 1-4 As shown, the clamp in this utility model is similar in structure to existing clamps. The main improvement of this utility model lies in the use of a horizontally elongated clamping frame 203, which, together with multiple sets of suction cups 210 evenly arranged on the clamping frame 203, equidistantly adsorbs the door sill plate, forming an adsorption fixation. This flexible adsorption clamping process maintains the center adsorption and the sides of the door sill plate material, avoiding scratches to the material itself during clamping, improving the safety of repair processing and reducing losses. The torque motor 103 and servo motor 107 in this utility model are existing technologies. When using this clamp, the user can first... The disc frame 106 is fitted with the threaded holes 108 around its perimeter and connected to the mounting machine or guide rail, etc., and the bolts are tightened. Then, the servo motor 107 can be used to control the turntable frame 105 connected to the bottom of the disc frame 106 to rotate and adjust the entire fixture. The rotating shaft 102 at the bottom of the support rod 104 can be driven by the torque motor 103 at one end, so that the positioning frame 201 fixed by the tripod 101 can be rotated and adjusted. Through the cooperation of the double-end rotating structure, the fixture can be adjusted in multiple angles during operation, which provides convenience for the repair of car door sills.

[0026] like Figure 2-4As shown, the clamping mechanism 2 includes a positioning frame 201. Electric telescopic rods 202 are connected to both ends of the top surface of the positioning frame 201. A clamping frame 203 is connected to the end of the electric telescopic rods 202. Circular holes 204 are opened on both sides of the clamping frame 203. Limiting posts 205 are fitted inside the inner walls of the circular holes 204. Buffer posts 206 are fitted inside the limiting posts 205. A rubber pad 207 is fixed to the top of the buffer post 206, and a high-pressure spring 208 is connected to the bottom of the buffer post 206. A suction cup post 209 is fixed at the center of the top surface of the frame 203. One end of the suction cup post 209 is connected to a suction cup 210, and the other end of the suction cup post 209 is connected to an air pipe frame 211. One end of the air pipe frame 211 is connected to a connecting pipe 212. During operation, the clamping frame 203 at the bottom of the fixture is lowered by the electric telescopic rod 202 until the multiple sets of suction cups 210 arranged on the bottom surface of the clamping frame 203 contact the workpiece. At this time, the air pipe frame 211 is connected to a negative pressure air pump through the connecting pipe 212. When the suction is activated, the suction cups 210 generate suction force to adhere and fix the workpiece. Subsequently, the electric telescopic rod 202 drives the clamping frame 203 to rise, and the two sides of the workpiece being suctioned rise and come into contact with the rubber pads 207 at the ends of the buffer piles 206 on both sides. As the elastic structure contracts, it maintains synchronous pressure on both sides of the workpiece, thus forming a clamping process of central suction and side restraint. By using a horizontally elongated clamping frame 203, in conjunction with multiple sets of suction cups 210 evenly arranged on the clamping frame 203, the door sill plate is equidistantly suctioned. After suction, the suction cups 210 can retract as a whole, so that the two sides of the door sill plate come into contact with the buffer piles 206. The buffer piles 206, in conjunction with the elastic structure and the rubber pads 207, can stably adhere to the suction surface of the door sill plate, forming a suction fixation. This flexible suction clamping process, which maintains central suction and side contact restraint on the door sill plate material, avoids scratches on the plate material itself during clamping, improves the safety of repair processing, and reduces losses.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
