Description

Technical Field

[0001] The utility model belongs to the field of glass clamp equipment, in particular to a clamp for processing a glass tube. Background Art

[0002] The glass tube processing fixture is a tool used to fix the glass tube during the glass tube processing process. At present, the glass tube processing fixture has some disadvantages. First, due to the lack of upper and lower multi-point clamping structure, the stability is insufficient when clamping the glass tube. Relying on a single clamping method alone, it is difficult to ensure that the glass tube is completely fixed during the processing, and it is easy to shake or displace. This disadvantage is mainly caused by the limitations of the fixture design. The conventional response method is to increase the clamping force, but this will bring new problems. On the one hand, excessive increase in clamping force may cause damage to the surface of the glass tube, especially for some thinner or fragile glass tubes, which are prone to indentation or even cracking. On the other hand, simply increasing the clamping force cannot fundamentally solve the stability problem. During the processing, the glass tube may still move slightly due to external force, affecting the processing accuracy. Moreover, constantly adjusting the clamping force will also consume time and energy, reducing processing efficiency, so it is necessary to propose a new structure to solve the above technical problems.

Used in conjunction with the clamping assembly, precise positioning of the glass tube is achieved, which provides a good foundation for subsequent processing operations and improves processing accuracy.

[0021] See also Figures 1 to 3 As the first embodiment of the utility model: the length and width of the bottom plate 100 match the length and width of the working plate 120, a column 110 is respectively installed at the four corners of the upper surface of the bottom plate 100, and the end of the column 110 away from the bottom plate 100 is connected to the four corners of the lower surface of the working plate 120, and a placement groove 121 is opened at the center of the upper surface of the working plate 120;

[0022] The placement groove 121 is an inverted triangle structure, and a plurality of anti-slip pads 122 are symmetrically and evenly installed on the inner wall at the bottom of the placement groove 121. Two cylinders 200 are symmetrically installed on the front edge and the rear edge of the lower surface of the working plate 120, and two telescopic rods 210 are symmetrically installed on the upper surface of the working plate 120 at positions matching the cylinders 200.

[0023] When in use, when the glass tube is to be processed, it is first clamped. When clamping, the user first slides the glass tube to the left or right side of the working plate 120 and places it in the placement groove 121. At this time, the outer surface of the glass tube abuts against the anti-slip pad 122 on the inner wall of the placement groove 121. After the placement is completed, the user can start the cylinder 200 to retract the telescopic rod 210 of the cylinder 200, thereby driving the clamping block 220 and the clamping plate 300 to move downward, thereby clamping and fixing the glass tube in the placement groove 121. When in use, the placement groove 121 on the working plate 120 provides a preliminary positioning area for the glass tube. After the glass tube is placed in the placement groove 121, the anti-slip pad 122 can prevent the glass tube from moving in the horizontal direction, ensuring the accurate position of the glass tube. Used in conjunction with the clamping assembly, accurate positioning of the glass tube is achieved, providing a good foundation for subsequent processing operations and improving processing accuracy.

[0024] See also Figures 1 to 3 As a second embodiment of the utility model: the ends of the two telescopic rods 210 on the front side and the rear side away from the working plate 120 are L-shaped and equipped with a clamping block 220, and the inner edge of the upper surface of the clamping block 220 is symmetrically provided with two threaded holes 221, and the inner edge of the lower surface of the clamping block 220 is equipped with a rubber pad 230, and the threaded hole 221 penetrates the rubber pad 230;

[0025] Two threaded holes 301 are symmetrically provided on the front edge and the rear edge of the upper surface of the clamping plate 300, respectively. The structure of the threaded hole 301 matches the structure of the threaded hole 221. The central axis of the threaded hole 301 is colinear with the central axis of the threaded hole 221. A butterfly screw 320 is installed inside the threaded hole 221. A clamping plate 300 is installed on the lower surface of a clamping block 220 on the front side and a clamping plate 300 on the rear side through the threaded hole 221, the threaded hole 301 and the butterfly screw 320.

[0026] A rubber pad 230 is provided between the clamping plate 300 and the clamping block 220, and a side surface of the triangular block 310 on the lower surface of the clamping plate 300 away from the clamping block 220 is provided with anti-slip grooves, and the center position of the lower surface of the clamping plate 300 matches the center position of the placement groove 121;

[0027] When in use, after the glass tube is placed in the placement groove 121, the user can start the four cylinders 200 simultaneously, so that the cylinder 200 drives the telescopic rod 210 to retract, thereby achieving the downward displacement of the clamping block 220, thereby driving the clamping plate 300 to move downward through the clamping block 220. At this time, the symmetrical triangular blocks 310 on the lower surface of the clamping plate 300 will abut against the outer surface of the glass tube. At this time, the two clamping plates 300 will abut and fix the outer surface of the glass tube. At this time, the glass tube is clamped and fixed in the placement groove 121 by the clamping assembly, and then the user can perform subsequent processing operations. Because when in use, the combination of the clamping assembly and the clamping plate 300 forms a multi-point clamping structure, the clamping block 220 and the clamping plate 300 of the upper clamping assembly are matched with the placement groove 121 on the lower side to fix the glass tube from the upper and lower directions, increasing the contact points, so that the glass tube is subjected to a uniform clamping force, which greatly improves the stability of the clamping and prevents it from shaking during the processing.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
