Description

Technical Field

[0001] The invention relates to the field of liquid crystal glass substrate production, in particular to a slider guide rail limiting clamp. Background Art

[0002] At present, the domestic liquid crystal substrate is mainly produced by the overflow down-pull method. In the equipment for producing liquid crystal substrates by the overflow down-pull method, the short roller mechanism is a mechanism used to realize the floating, separation and withdrawal of the short roller on the glass manufacturing furnace. It usually includes a short roller component, a sliding component and a sealing component. Among them, the sliding component that realizes the short roller entering and exiting the glass manufacturing furnace is a linear guide slider structure;

[0003] In the actual production process, after the short roller reaches the specified insertion depth, it is necessary to limit the relative position of the slider and the guide rail in the linear guide slider structure. The traditional threaded clamping fixture cannot intuitively reflect whether the clamp is loosened or clamped. Therefore, when the slider cannot slide (including some guide rails that are dirty or physically blocked, causing the slider to be unable to slide), the operator will habitually loosen the thread continuously, which will not only damage the guide rail clamp, but also cause the short roller mechanism to lose its limiting function. Therefore, providing a slider guide rail limiting clamp has become a difficult problem to be solved by relevant technicians in this technical field. Summary of the invention

At the same time, a spring is installed on the outside of the sliding column, and one end of the spring is fixedly arranged on the side wall of the guide channel, and the other end of the spring is fixedly arranged on the clamping block.

[0010] Furthermore, the clamping block includes a docking groove opened on its surface, and the docking groove is adapted to the size of the docking strip, and the docking strip and the docking groove are evenly arranged in three groups, and the three groups of docking strips are respectively inserted into the inside of the three groups of docking grooves.

[0011] Furthermore, the cross-sections of the docking grooves and the docking strips are both dovetail structures, and the clamping block and the clamping plate are positioned and installed through three sets of docking strips and docking grooves. At the same time, the clamping plate is rectangular and the clamping block is circular.

[0031] Specific implementation method 1: Please refer to Figure 1-9 The present invention provides a technical solution: a slider guide rail limit clamp, comprising a clamp body 1, sliders 2 are fixedly installed on both sides of the bottom of the clamp body 1, and guide channels 7 are provided inside the two groups of sliders 2, and sliding columns 9 are movably installed inside the guide channels 7, and a clamping block 5 is fixedly installed at the end of the sliding column 9, and a mounting column 13 is movably installed on the side of the sliding column 9 away from the clamping block 5 through a bearing, and a thread 10 is provided on the outer side of the mounting column 13, and the mounting column 13 is screwed and installed inside a wedge seat 14 through the outer thread 10, and A wedge block 11 is installed on the inner upper side of the wedge seat 14, a knob 6 is installed on the side of the mounting column 13 away from the thread 10, a connecting column 12 is installed on the upper side of the wedge block 11, and a pressure strip 3 is installed on the end of the connecting column 12 away from the wedge block 11, and a transmission arm 17 is fixedly installed on the side wall of the pressure strip 3, and the transmission arm 17 is movably connected to the handle 4 through a pin shaft, the bottom of the handle 4 is movably connected to the transmission plate 15 through a pin shaft, and a mounting seat 16 is movably installed on the bottom of the transmission plate 15 through a pin shaft, and the mounting seat 16 is screwed and fixed to the workbench of the clamp body 1.

[0032] Working principle: when it is necessary to clamp the guide rail, press the handle 4 downward, the handle 4 moves through the transmission plate 15, the mounting seat 16, and the transmission arm 17, and then drives the pressure strip 3 to move. During the movement of the pressure strip 3, the two connecting columns 12 are squeezed downward at the same time, and the connecting column 12 drives the wedge block 11 to move downward. The downward pressing inclined surface of the lower surface of the wedge block 11 conflicts with the force-bearing inclined surface provided on the wedge seat 14, and the wedge block 11 pushes the wedge seat 14 to move in the direction of the guide channel 7 provided in the slider 2. When the wedge seat 14 moves, it drives the mounting column 13, the knob 6, the sliding column 9 and the clamping block 5 to move, and the spring 8 is stretched to reduce the distance between the two clamping blocks 5. By reducing the distance between the two clamping blocks 5, the clamping of the guide rail is completed. The purpose is to limit the relative position of the slider 2 and the guide rail; on the contrary, when loosening the guide rail, the handle 4 is lifted upward, and the handle 4 drives the clamp assembly to move. The clamp assembly includes a transmission plate 15, a mounting seat 16 and a transmission arm 17, and the pressure strip 3 moves upward away from the connecting column 12, and the wedge block 11 moves upward away from the wedge seat 14. The elastic force of the spring 8 restores its original length and drives the two clamps 5 to move away from the guide rail, and the clamp block 5 loosens the guide rail; it is worth noting that if the guide rail is not located in the center of the slide groove, a thread 10 is opened on the outer wall of the mounting column 13, and the wedge seat 14 is threadedly connected to the thread 10 on the mounting column 13, and the knob 6 can be rotated, and the knob 6 drives the mounting column 13 fixedly connected thereto to rotate, and the mounting column 13 is mounted on the sliding column 9 through a bearing. At one end, the connecting column 12 limits the wedge seat 14 through the wedge block 11 and the inclined groove, so the position of the wedge seat 14 on the mounting column 13 moves, and the distance between the wedge seat 14 and the clamping block 5 changes to adapt to guide rails at different positions; when the clamping block 5 is clamping and fixing the guide rail, the clamping plate 52 is held by hand, and the clamping block 5 and the clamping plate 52 are positioned and installed through three groups of docking strips 51 and docking grooves 50. At the same time, the clamping plate 52 is rectangular, and the surface area of ​​the clamping block 5 is much smaller than the surface area of ​​the clamping plate 52, which can improve the clamping area of ​​the guide rail, complete the stability and strength of the guide rail clamping, and at the same time, a clamping piece 56 is provided on the front side of the clamping plate 52. When the clamping piece 56 clamps the guide rail under force At this time, the guide column 53 is inserted into the guide hole opened on the clamping plate 52, so as to ensure the stability of the clamping piece 56 during movement and prevent it from tilting. At the same time, a buffer spring 54 is installed on the outside of the guide column 53. Through the setting of the buffer spring 54, when the clamping piece 56 squeezes the guide rail, the buffer spring 54 is compressed and deformed to avoid clamping damage to the guide rail; a plurality of groups of positioning grooves 561 are evenly arranged on the surface of the clamping piece 56, and positioning strips 57 are inserted in the interior of the plurality of positioning grooves 561, and clamping strips 571 are arranged on the outside of a large number of positioning strips 57. The clamping strip 571 is a rectangular structure made of rubber material, which realizes the elastic clamping of the guide rail and avoids scratches on the guide rail.
