Description

Technical Field

[0001] The utility model relates to the technical field of tempered glass processing equipment, in particular to a tempered glass positioning device. Background Art

[0002] Tempered glass is a kind of prestressed glass. To improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc. Tempered glass is not only used for windows, but some thicker tempered glass is used for desktops. Tempered glass used as desktops is mostly round and square, and it is necessary to drill holes and grind the edges of the tempered glass before installation.

[0003] Tempered glass needs to be clamped and fixed before processing. The traditional clamping method mostly uses the clamping claw method. When installing and disassembling tempered glass, multiple sets of clamps need to be adjusted. It is not easy to position round and square tempered glass. The operation is complicated. At the same time, the clamping points need to be adjusted multiple times, which prolongs the processing time of tempered glass.

[0004] To this end, the utility model provides a tempered glass positioning device, which simultaneously drives four sets of driven bevel gears to rotate through a transmission bevel gear, so that four clamping plates move to the center position of a workbench to solve the above problem.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a tempered glass positioning device, including a workbench, a top of the workbench is symmetrically provided with a slide groove, the interior of the slide groove is provided with a positioning clamping assembly, the positioning clamping assembly includes a clamping plate slidably connected to the interior of the slide groove, the bottom end of the workbench is fixedly connected to a bottom shell, the interior of the bottom shell is rotatably connected to a transmission bevel gear, the outer end of the transmission bevel gear is meshed with a driven bevel gear, the outer end of the driven bevel gear is fixedly connected to a screw rod, the screw rod is rotatably connected to the interior of the slide groove, and the screw rod and the clamping plate are threadedly connected.

[0007] Preferably, the inner wall of the clamping plate is arc-shaped and is provided with a clamping hole, the cross section of the clamping hole is triangular, and the sliding grooves are provided with four groups and are opened in an oblique shape.

[0008] Preferably, the positioning clamping assembly further comprises a rotating rod fixedly connected to the bottom end of the transmission bevel gear, and the rotating rod is rotationally connected to the bottom shell.

[0009] Preferably, clamping blocks are symmetrically and fixedly connected to both sides of the inner cavity of the clamping plate, a resisting block is slidably connected inside the clamping block, and a first spring is fixedly connected between the clamping block and the resisting block.

[0012] Beneficial Effects

[0013] The utility model provides a tempered glass positioning device. Compared with the prior art, it has the following beneficial effects:

[0014] (1) The tempered glass positioning device drives four sets of driven bevel gears to rotate simultaneously through the transmission bevel gear, so that four sets of clamps move simultaneously. Since the slide groove is arranged in an oblique shape, the four sets of clamps move toward the center of the workbench, and can automatically position the position of the tempered glass, so that the center of the tempered glass is coaxial with the center of the workbench, thereby improving the precision of tempered glass processing. The inner wall of the clamp is arranged in an arc shape, which can clamp round glass. The provided clamping holes can clamp the corners of square glass. The glass is clamped and fixed by the pressure of the four clamps, which is convenient for installation and disassembly.

[0015] (2) The tempered glass positioning device uses the elastic force generated by the first spring to enable the abutment blocks in the clamp to press from both sides of the glass, thereby improving the stability of the glass inside the clamp. The abutment column can support the center position of the glass. At the same time, the sliding rods inside the four groups of support rods provide support force from the center position of the glass to four points outward. The four support points disperse the pressure on the glass to prevent the glass from breaking during processing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] See also Figure 1-5 A tempered glass positioning device comprises a workbench 1, a slide groove 2 is symmetrically opened at the top of the workbench 1, a positioning clamping assembly 3 is arranged inside the slide groove 2, the positioning clamping assembly 3 comprises a clamping plate 301 slidably connected to the inside of the slide groove 2, a bottom shell 302 is fixedly connected to the bottom end of the workbench 1, a transmission bevel gear 303 is rotatably connected to the inside of the bottom shell 302, a driven bevel gear 304 is meshed at the outer end of the transmission bevel gear 303, a screw rod 305 is fixedly connected to the outer end of the driven bevel gear 304, the screw rod 305 is rotatably connected to the inside of the slide groove 2, and a threaded connection is formed between the screw rod 305 and the clamping plate 301. Next, when processing round or square glass, the positioning and clamping assembly 3 further includes a rotating rod 306 fixedly connected to the bottom end of the transmission bevel gear 303, and the rotating rod 306 is rotatably connected to the bottom shell 302, and the tempered glass is placed on the outer end of the support column 7 at the top of the workbench 1. At this time, the transmission bevel gear 303 connected to the rotating rod 306 is rotated, and the rotating transmission bevel gear 303 drives the four sets of driven bevel gears 304 and the screw rod 305 fixed at the outer end to rotate simultaneously, and the rotating screw rod 305 drives the clamping plate 301 to slide in the slide groove 2 at the top of the workbench 1, thereby clamping and fixing the tempered glass from four directions;

[0026] The inner wall of the clamping plate 301 is arc-shaped and has a clamping hole. The cross-section of the clamping hole is triangular. There are four groups of slide grooves 2 and they are obliquely opened. The clamping plate 301 with an arc-shaped inner wall can clamp round glass, and the triangular clamping holes can clamp the four corners of square tempered glass. The obliquely arranged slide groove 2 allows the four clamping plates 301 to move toward the center of the workbench 1 at the same time, which is convenient for clamping and disassembling the tempered glass, and allows the glass to move so that it is coaxial with the workbench 1 for easy positioning. At the same time, the clamping of the tempered glass is achieved through the extrusion force between the four groups of clamping plates 301 and the glass, and does not require specific clamping parts, making the operation more convenient.

[0027] Embodiment 2:

[0028] See also Figure 1-6 This embodiment provides a technical solution for a tempered glass positioning device based on the first embodiment: clamping blocks 4 are symmetrically fixedly connected to both sides of the inner cavity of the clamping plate 301, and a stop block 5 is slidably connected inside the clamping block 4. A first spring 6 is fixedly connected between the clamping block 4 and the stop block 5. When the tempered glass is inserted into the inside of the clamping plate 301, the elastic force generated by the first spring 6 causes the stop block 5 inside the clamping block 4 to clamp the glass from both sides, thereby enhancing the stability of the glass during processing;

[0029] The cross section of the clamp block 4 is a right-angled trapezoid, and the clamp block 4 arranged in a right-angled trapezoid enables the glass to slide into the interior of the clamping plate 301 when squeezed. The cross section of the stop block 5 is a triangle, and the stop block 5 arranged in a triangle reduces the contact area between it and the glass, thereby reducing the friction force when the glass moves, achieving a certain clamping effect and facilitating the movement of the glass during the positioning and clamping process;

[0030] A support column 7 is fixedly connected to the top of the workbench 1, and a support rod 8 is fixedly connected to the outer end of the support column 7. A sleeve rod 9 is fixedly connected to the inside of the support rod 8, and a slide rod 10 is slidably connected to the inside of the sleeve rod 9. A second spring 11 is fixedly connected between the slide rod 10 and the sleeve rod 9. Four groups of support rods 8 are provided, and the four groups of support rods 8 are arranged in a cross shape. When the glass is clamped, the support column 7 provides supporting force to the center of the glass. At the same time, when the glass is placed, the elastic force generated by the second spring 11 buffers the pressure of the glass, and the four slide rods 10 provide supporting force from the center of the glass to four points outward. The four supporting points disperse the pressure on the glass to prevent the glass from breaking during processing.
