The utility model relates to the technical field of glass processing. The positioning and clamping device for processing glass cover plates achieves the purpose of improving the safety of positioning and clamping of glass cover plates and reducing damage caused by clamping of glass cover plates.

[0004] This patented technology has the advantage of preventing foreign objects on the fixture from scratching the glass when in use, but there are still some shortcomings during use. When drilling or cutting, in order to stabilize the glass cover and prevent it from breaking, it is usually necessary to clamp its sides with clamps. However, when coating is required, such as optical coating or protective film, clamping the glass cover will hinder the processing and cannot be carried out effectively. There are limitations. For this reason, we propose a clamping device for fixing the glass cover to solve the existing problems. Utility Model Content

[0005] The utility model aims to solve the problems existing in the background technology and propose a clamping device for fixing a glass cover.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping device for fixing a glass cover plate, comprising a suction cup, a base plate, a mounting plate, a screw, a negative pressure pump and a mounting tube, a mounting plate is arranged above the base plate, a cross-intersecting adjustment groove and a symmetrically distributed travel groove are provided inside the mounting plate, a motor 1 is arranged on the rear side of the mounting plate, a screw is arranged at the output end of the motor 1, nuts are rotatably sleeved at both ends of the screw, the threads on the outer wall of the screw are relatively distributed, a clamping block is arranged at the upper end of the nut, a connecting box is arranged at the lower end of the mounting plate, a negative pressure pump is connected and installed at the lower end of the connecting box, a mounting tube is arranged inside the adjusting groove, and a suction cup is arranged at the upper end of the mounting tube.

[0007] When using the clamping device for fixing the glass cover plate in the present solution, when the motor drives the screw rod to rotate, the threads relatively distributed on the outer wall push the two nuts relative to or away from each other, and because the clamping block at the upper end of the thread moves in the stroke groove through the slider, the clamping block is driven to move relative to or away from each other, thereby clamping the glass cover plate at the upper end of the mounting plate. The glass cover plate fixed between the clamping plates is convenient for cutting, drilling and other processing. During the processing, the second motor drives the mounting shaft to rotate, driving the mounting plate to rotate, so that the mounting plate rotates;

[0008] At the same time, the glass cover can be placed on the suction cup, and the mounting tube can slide inside the adjusting groove when in use. The mounting tube can be lifted by rotating the threaded sleeve on the thread on the outer wall of the mounting tube. When the limiting ring contacts the lower end of the mounting plate, the mounting tube is limited, and the upper end of the mounting tube is squeezed by the rotation of the threaded sleeve, so that the mounting tube is fixed in the adjusting groove at the position, which is suitable for the adsorption of glass covers of different specifications. The suction force of the negative pressure pump acts on the inside of the connecting box, and the negative pressure of the connecting box acts on the negative pressure tube, and acts on the inside of the suction cup through the mounting tube, so as to adsorb the lower end of the glass cover, thereby realizing the adsorption and fixation of the glass cover.

[0009] Preferably, the upper end of the bottom plate is provided with symmetrically distributed bearing brackets, and both ends of the mounting plate are provided with mounting shafts rotatably mounted inside the bearing brackets. The mounting shafts are rotationally supported by the bearing brackets to rotationally support the mounting plate.

[0010] Preferably, a second motor fixedly connected to the mounting shaft is provided on one side above the bottom plate. The mounting shaft is driven to rotate by the operation of the first motor, thereby realizing automatic adjustment of the angle of the mounting plate.

[0011] Preferably, the lower end of the installation tube is connected to a negative pressure tube that penetrates the connection box. The negative pressure suction force of the suction pump acting on the inside of the connection box is diverted to the inside of the negative pressure tube and acts on the installation tube.

[0012] Preferably, the upper outer wall of the mounting tube is sleeved with a threaded sleeve, and the outer wall of the mounting tube is provided with threads adapted to the threaded sleeve. The threaded sleeve is threadedly sleeved on the outer side of the mounting tube, and the bite force of the threads fixes the threaded sleeve at the position of the screwed-in outer wall of the mounting tube.

[0013] Preferably, a limiting ring is provided at the lower end of the mounting tube, and the diameter of the limiting ring is larger than the width of the adjustment groove. The limiting ring limits the lower end of the mounting tube to prevent the mounting tube from completely leaving the adjustment groove.

[0014] Preferably, both ends of the clamp block are provided with sliders, and the sliders are slidably installed inside the travel groove. The clamp block slides inside the travel groove through the sliders, and the clamp block is guided to slide along the travel groove.

[0015] Preferably, a bearing seat is provided at the lower end of the mounting plate, and the middle section of the screw is rotatably inserted into the bearing seat. The screw is rotatably supported inside the bearing seat, and the stability of the screw is improved when it rotates.

[0016] Preferably, the outer side of the screw is sleeved with a protective sleeve fixedly connected to the outer wall of the bearing seat, the nut is located inside the protective sleeve, and a laser light is arranged at the inner center of the upper end of the mounting plate. The protective sleeve protects the outer side of the screw, so that the nut can effectively move inside it, and the negative pressure tube is intercepted by the protective sleeve when moving, so as to prevent the negative pressure tube from contacting the screw, and the laser light plays a role in positioning the center of the glass cover.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] 1. The utility model provides relatively movable clamping blocks on the mounting plate to clamp the sides of the glass cover plate, so as to facilitate the fixation of the glass cover plate during operations such as drilling and cutting. When covering processing such as coating and film lamination is required, the glass cover plate is placed on the suction cup, and the end of the glass cover plate opposite to the processing surface is fixed by negative pressure suction force, so that the glass cover plate can be adapted to perform different types of processing, and the positions of the clamping blocks and the suction cup can be adjusted, so that glass cover plates of different specifications can be fixed during processing, and multi-functional use is achieved, and the adaptability and flexibility of the use process are high.
