[0001] The utility model relates to the technical field of automobile glass processing, and specifically relates to an automobile glass clamp. Background Technique

[0002] As an important part of an automobile, the main functions of automobile glass are to resist wind and cold, prevent rain, dust, and provide sound insulation and sun protection. There are many types of automobile glass, such as laminated glass, tempered glass, insulating glass, etc.; during the production process of automobile glass, a series of processes such as cutting, grinding, and gluing of the glass are required, and these process operations need to clamp and fix the glass.

[0003] When the existing clamp clamps and fixes the automobile glass, the clamping jaws apply force to the glass surface. If the force is too large, it is easy to cause damage to the glass surface, and if the force is too small, it is easy to cause unstable clamping, affecting the processing of the glass. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the utility model provides an automobile glass clamp, which has the advantages of flexible clamping and stable clamping, and solves the problem that the existing device is easy to damage the glass surface.

[0005] To achieve the above object, the utility model provides the following technical solution: an automobile glass clamp, including a platform, the platform has a cavity inside, a screw rod is rotatably connected inside the cavity of the platform, chutes are opened on both sides of the upper end surface of the platform, the chutes penetrate through the cavity inside the platform, two sliders are slidably connected to the inner wall of the chutes, the vertical parts of the sliders are slidably connected to the chutes, the bottoms of the sliders are slidably connected to the cavity inside the platform, the two sliders are threadedly connected to the screw rod, and clamping components are connected to the tops of the vertical parts of the sliders;

[0006] The clamping component includes a fixing plate, a clamping plate and a mounting plate. The fixing plate and the mounting plate are movably installed at the top of the vertical part of the slider, and the upper end surface of the fixing plate and the upper end surface of the platform are on the same horizontal plane. A moving block is slidably connected to the upper end surface of the fixing plate. A cylinder is movably installed on one side of the mounting plate, and one end of the piston rod of the cylinder is movably installed with the moving block;

[0007] Guide grooves are opened at both ends of the moving block, and guide posts are arranged on both sides of one end of the clamping plate. The guide posts are slidably connected to the inner wall of the guide grooves;

[0009] Further, the screw rod is a double-threaded screw rod, and a turning handle is rotatably connected to one end of the screw rod.

[0010] Further described, a nano - coating is sprayed on the upper end surface of the platform, or the upper end surface of the platform is made of glass material.

[0011] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0012] 1. For this automotive glass fixture, through the optimized design of the clamping assembly, the guiding column at one end of the clamping plate is slidably connected to the guiding groove on the moving block. Driven by the cylinder, the moving block slides on the upper end surface of the fixed plate.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment

[0021] Given by Figures 1-3 Figures 1-3 There is provided an automotive glass fixture, which includes a platform 1. The platform 1 has a cavity inside. A screw rod 2 is rotatably connected inside the cavity of the platform 1. Both sides of the upper end surface of the platform 1 are provided with sliding grooves 11. The sliding grooves 11 penetrate through the cavity inside the platform 1. Two sliding blocks 3 are slidably connected to the inner wall of the sliding grooves 11. The vertical parts of the sliding blocks 3 are slidably connected to the sliding grooves 11. The bottoms of the sliding blocks 3 are slidably connected to the cavity inside the platform 1. The two sliding blocks 3 are threadedly connected to the screw rod 2. Clamping assemblies 4 are connected to the tops of the vertical parts of the sliding blocks 3.

[0022] In this embodiment, by placing the glass on the platform 1, rotating the screw rod 2 drives the relative movement of the sliding blocks 3. The vertical parts of the sliding blocks 3 and the clamping assemblies 4 are slidably connected to the sliding grooves 11. The original state of the clamping assemblies 4 is a closed state. The side end surface of the clamping plate 44 contacts one side end surface of the glass. By continuously moving the sliding blocks 3 and the clamping assemblies 4, the clamping plate 44 pushes the glass to slide on the surface of the platform 1, and slides the glass to the central position, facilitating the clamping operation of the clamping assemblies 4 on both sides of the glass.

[0023] It can be understood that the original state of the clamping assemblies 4 is a closed state, and the lower end surface of the clamping plate 44 is close to the upper end surface of the fixing plate 41. At the same time, pushing the glass to the central position facilitates that after the mounting plate 47 is opened, the rotating screw rod 2 drives the bottom end surface of the glass to slide on the upper end surface of each fixing plate 41, so that the area of the force exerted on the glass surface by each mounting plate 47 is the same, increasing the clamping stability.

[0024] It should be noted that the upper end surface of the platform 1 is sprayed with a nano - coating, or the upper end surface of the platform 1 is made of glass material. By setting the material of the upper end surface of the platform 1, it can prevent the upper end surface of the platform 1 from wearing the bottom end surface of the glass when the glass slides to adjust the central position.

[0025] Specifically, please refer to Figure 3 Figure 3 , in order to increase the clamping stability, the clamping assembly 4 includes a fixing plate 41, a clamping plate 44 and a mounting plate 47. The fixing plate 41 and the mounting plate 47 are movably installed at the top of the vertical part of the sliding block 3, and the upper end surface of the fixing plate 41 and the upper end surface of the platform 1 are on the same horizontal plane. A moving block 42 is slidably connected to the upper end surface of the fixing plate 41. A cylinder 48 is movably installed on one side of the mounting plate 47. One end of the piston rod of the cylinder 48 is movably installed with the moving block 42. Guide grooves 43 are opened on both side ends of the moving block 42. Guide posts 45 are provided on both sides of one end of the clamping plate 44. The guide posts 45 are slidably connected to the inner wall of the guide grooves 43.

[0026] In this embodiment, by setting the upper end surface of the fixed plate 41 to be horizontal with the upper end surface of the platform 1, the bottom of the moving block 42 is slidably connected to the fixed plate 41, the guide columns 45 on both sides of the clamping plate 44 are slidably connected to the guide grooves 43, and the cylinder 48 drives the moving block 42 to slide horizontally. Under the guidance of the guide grooves 43, the guide columns 45 drive the clamping plate 44 to move vertically to achieve opening. Similarly, the horizontal movement of the moving block 42 can drive the clamping plate 44 to move vertically and achieve clamping and closing, so as to realize the stable clamping of the glass through the cooperation of the clamping plate 44 and the fixed plate 41.

[0027] Specifically, please refer to Figures 2-3 , in order to achieve flexible clamping and reduce damage to the glass, a silica gel strip 46 is movably connected between the upper end surface of the fixed plate 41 and the lower end surface of the clamping plate 44. The silica gel strip 46 is made of elastic silica gel material and has good ductility. The screw rod 2 is a double-threaded screw, and a turning handle 21 is rotatably connected to one end of the screw rod 2. The upper end surface of the platform 1 is sprayed with a nano-coating, or the upper end surface of the platform 1 is made of glass material.

[0028] In this embodiment, by setting the screw rod 2 as a double-threaded screw and assembling a turning handle 21 at one end of the screw rod 2, by manually rotating the screw rod 2, the rotating screw rod 2 drives the slider 3 to move gently. By applying force to squeeze both sides of the glass, the glass is pushed to the central position, which facilitates the stability of subsequent clamping and also reduces the excessive squeezing force that is likely to be caused by motor drive, thereby causing the glass to break.

[0029] By providing a flexible silica gel strip 46 between the clamping plate 44 and the fixed plate 41, the rotating screw rod 2 pushes the fixed plate 41 to slide on the bottom end surface of the glass. One side of the glass squeezes the silica gel strip 46, and the cylinder 48 drives the moving block 42 to move horizontally. The clamping plate 44 moves vertically and clamps the glass surface with the fixed plate 41. The silica gel strip 46 is in a side U-shaped state, which can not only prevent slipping during clamping, increase the stability of clamping, but also protect the glass surface from being damaged.

[0030] The working principle of the above embodiment is:

[0031] Place the glass on the platform 1. Rotate the screw rod 2 by holding the rotating handle 21. The screw rod 2 drives the slider 3 and the clamping assembly 4 to move relatively. One side of the closed clamping assembly 4 pushes the glass to slide on the upper end surface of the platform 1, realizing the adjustment of the central position of the glass, which is convenient for the four groups of clamping assemblies 4 to clamp both sides of the glass well. After adjusting the position, the piston rod of the cylinder 48 extends and drives the moving block 42 to slide horizontally. The clamping plate 44 moves vertically upward under the guidance of the guiding groove 43. Continue to rotate the screw rod 2, and the four groups of clamping assemblies 4 move relatively. The fixing plate 41 slides along the bottom end surface of the glass, and both sides of the glass squeeze the silica gel strip 46 at the same time. The four groups of silica gel strips 46 will undergo elastic deformation as the fixing plate 41 moves. Along the arc of the deformation of the silica gel strip 46, the whole glass will move slightly upward. At the same time as the upward movement, the piston rod of the cylinder 48 contracts and drives the moving block 42 to move horizontally, and the clamping plate 44 moves downward and presses the glass surface. At this time, the silica gel strip 46 is in a side U shape, so as to realize the stable clamping and flexible clamping of the glass and reduce the damage to the glass surface.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
