Technical Field

[0001] The present application relates to the technical field of diode glass shell manufacturing, and in particular to a glass tube fixing device for a tube cutting machine. Background Art

[0002] Glass cutting is the first process in the glass deep processing and is also the most commonly used process. Use a glass tube cutting machine to cut long glass tubes into short tubes according to process parameters.

[0003] The patent document with the publication number CN204369757U provides a glass tube fixing device for a tube cutting machine, which is composed of a positioning frame and three copper claws arranged thereon, and is characterized in that an adjustment plate is arranged on the circular working surface of the claw, a long groove is arranged at the bottom of the copper claw, and a short groove is arranged at the rear. The copper claw adjustable device avoids frequent removal of the copper claw when replacing the glass tube, ensures the consistency of the size of the produced and processed products, effectively reduces the labor intensity of the workers, and reduces the cost.

[0004] In actual use, when the above device is used to adjust and fix glass tubes of different diameters, the outer diameter of the glass tube needs to be adjusted by replacing different adjustment pieces. It is still troublesome to prepare adjustment pieces of various sizes. Therefore, we propose a glass tube fixing device for a tube cutting machine. Utility Model Content

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a glass tube fixing device for a tube cutting machine, comprising a fixed outer ring, three groups of adjustment mechanisms are arranged on the fixed outer ring, the adjustment mechanisms include two groups of sliding rods, both groups of sliding rods are slidably connected to the inside of the fixed outer ring, and both groups of sliding rods are passed through the fixed outer ring, limiting blocks are fixedly installed at the bottom ends of the two groups of sliding rods, the top of the limiting block is located between the two groups of sliding rods and a spring is installed, the end of the spring away from the limiting block is installed on the inner ring of the fixed outer ring, connecting blocks are fixedly installed on the top of the outer walls of the two groups of sliding rods, the internal threads of the connecting blocks are connected with bolts, and the outer wall of the fixed outer ring is provided with a threaded groove matching the rotating block.

[0007] By adopting the above technical scheme, the glass tube is placed inside the fixed outer ring and between the three groups of limit blocks. The outer walls of glass tubes with different diameters squeeze the limit blocks to different degrees. The spring automatically contracts under its own elasticity and can automatically match the sizes of different glass tubes. At the same time, the spring can automatically drive the limit blocks to conflict with the outer wall of the glass tube under its own elasticity. After the glass tube is installed, the bolts are connected to the thread grooves by rotating the bolts to limit the position of the limit blocks, so that the limit blocks are not affected by the springs. When replacing the glass tube, it is only necessary to adjust the three groups of bolts to separate from the thread grooves to take out the glass tube, which is beneficial to ensure the fixing effect of the glass tube. The position of the limit blocks is changed through the elastic action of the spring, which is beneficial to be suitable for glass tubes with different diameters. There is no need to prepare adjustment sheets of various sizes, which improves convenience during use.

[0008] As a preferred technical solution of the present application, a telescopic guide rod is arranged inside the spring, the bottom end of the telescopic guide rod is fixedly mounted on the inner ring of the fixed outer ring, and the telescopic end of the telescopic guide rod is mounted on the top of the limit block.

[0009] By adopting the above technical solution, the telescopic guide rod plays a guiding role in the elastic expansion and contraction of the spring, which is beneficial to improving the service life of the spring.

[0010] As a preferred technical solution of the present application, a limiting groove is provided on a side of the limiting block away from the spring.

[0011] By adopting the above technical solution, when the limiting block fixes the glass tube through the limiting groove, there are two fixing points, which increases the limiting effect on the glass tube and improves the fixing effect of the device on the glass tube.

[0012] As a preferred technical solution of the present application, the corners of the limit block are all set to be rounded.

[0013] By adopting the above technical solution, the corners of the limiting blocks are all set as rounded corners, which can avoid the corners of the limiting blocks from causing damage to the glass tube, thereby improving the protection effect on the glass tube.

[0014] As a preferred technical solution of the present application, a rotating block is fixedly connected to the top end of the bolt, and a resistance-increasing strip is engraved on the outer surface of the rotating block.

[0015] By adopting the above technical solution, the bolt is adjusted by rotating the rotating block, and the resistance-increasing strip increases the friction between the hand and the rotating block, thereby improving the practicality during use.

[0016] As a preferred technical solution of the present application, a resistance-enhancing layer is fixedly connected to the outer surface of the limit block.

[0017] By adopting the above technical solution, the friction between the limit block and the glass tube is increased by the resistance-increasing layer, thereby improving the fixing effect of the glass tube.

[0018] Beneficial effects of this application:

[0019] 1. By placing the glass tube inside the fixed outer ring and between the three groups of limit blocks, the outer walls of glass tubes with different diameters squeeze the limit blocks to different degrees, and the spring automatically contracts under its own elastic action to automatically match the sizes of different glass tubes. At the same time, the spring can automatically drive the limit blocks to conflict with the outer wall of the glass tube under its own elastic action. After the glass tube is installed, the bolts are connected to the thread grooves by rotating the bolts to limit the position of the limit blocks so that the limit blocks are not affected by the springs. When replacing the glass tube, it is only necessary to adjust the three groups of bolts to separate from the thread grooves to take out the glass tube, which is beneficial to ensure the fixing effect of the glass tube. The position of the limit blocks is changed through the elastic action of the spring, which is beneficial to be suitable for glass tubes with different diameters.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Reference Figure 1-3A glass tube fixing device for a tube cutting machine comprises a fixed outer ring 1, on which three groups of adjustment mechanisms 2 are arranged, the adjustment mechanisms 2 comprise two groups of sliding rods 201, both of which are slidably connected to the inside of the fixed outer ring 1, and both of which are penetrated by the fixed outer ring 1, and the bottom ends of the two groups of sliding rods 201 are fixedly installed with a limit block 202, and the top end of the limit block 202 is located between the two groups of sliding rods 201 and is installed with a spring 203, and one end of the spring 203 away from the limit block 202 is installed on the inner ring of the fixed outer ring 1, and the top of the outer wall of the two groups of sliding rods 201 is fixedly installed with a connecting block 204, and the inner thread of the connecting block 204 is connected with a bolt 205, and the outer wall of the fixed outer ring 1 is provided with a thread groove 206 matching with the rotating block 5. A limit groove 4 is provided on the side of the limit block 202 away from the spring 203.

[0027] By placing the glass tube into the fixed outer ring 1 and placing it between the three groups of limit blocks 202, the outer walls of glass tubes with different diameters squeeze the limit blocks 202 to different degrees, and the spring 203 automatically contracts under its own elastic action and can automatically match the sizes of different glass tubes. At the same time, the spring 203 can automatically drive the limit blocks 202 to conflict with the outer wall of the glass tube under its own elastic action. After the glass tube is installed, the bolt 205 is connected to the thread groove 206 by rotating the bolt 205 to limit the position of the limit block 202, so that the limit block 202 is not affected by the spring 203. When replacing the glass tube, it is only necessary to adjust the three groups of bolts 205 to separate from the thread groove 206 to take out the glass tube, which is beneficial to ensure the fixing effect of the glass tube. The position of the limit block 202 is changed by the elastic action of the spring 203, which is beneficial to be suitable for glass tubes with different diameters. There is no need to prepare adjustment sheets of multiple sizes, which improves convenience during use. When the limiting block 202 fixes the glass tube through the limiting groove 4, there are two fixing points, which increases the limiting effect on the glass tube and improves the fixing effect of the device on the glass tube.

[0028] Reference Figure 1-3 A telescopic guide rod 3 is provided inside the spring 203, the bottom end of the telescopic guide rod 3 is fixedly mounted on the inner ring of the fixed outer ring 1, and the telescopic end of the telescopic guide rod 3 is mounted on the top of the limit block 202. The corners of the limit block 202 are all set as rounded corners. The outer surface of the limit block 202 is fixedly connected with a resistance-increasing layer 7; the telescopic guide rod 3 plays a guiding role in the elastic expansion and contraction of the spring 203, which is beneficial to improving the service life of the spring 203. The corners of the limit block 202 are all set as rounded corners, so as to avoid the corners of the limit block 202 from causing damage to the glass tube, thereby improving the protection effect on the glass tube. The resistance-increasing layer 7 increases the friction between the limit block 202 and the glass tube, thereby improving the fixing effect on the glass tube.

[0029] Reference Figure 2The top end of the bolt 205 is fixedly connected with a rotating block 5, and a resistance-increasing strip 6 is engraved on the outer surface of the rotating block 5; the bolt 205 is adjusted by rotating the rotating block 5, and the resistance-increasing strip 6 increases the friction between the hand and the rotating block 5, thereby improving the practicality during use.

[0030] Working principle: by putting the glass tube into the fixed outer ring 1 and placing it between the three groups of limit blocks 202, the outer walls of glass tubes with different diameters squeeze the limit blocks 202 to different degrees, and the spring 203 automatically contracts under its own elasticity to automatically match the sizes of different glass tubes. At the same time, the spring 203 can automatically drive the limit blocks 202 to conflict with the outer walls of the glass tube under its own elasticity. After the glass tube is installed, the bolt 205 is turned to connect the bolt 205 with the thread groove 206 to adjust the position of the limit block 202. The limit block 202 is limited so that it is not affected by the spring 203. When replacing the glass tube, it is only necessary to adjust the three sets of bolts 205 to separate from the thread groove 206 to remove the glass tube, which is conducive to ensuring the fixing effect of the glass tube. The position of the limit block 202 is changed by the elastic action of the spring 203, which is conducive to being suitable for glass tubes of different diameters. There is no need to prepare adjustment pieces of various sizes, which improves the convenience of use. The telescopic guide rod 3 plays a guiding role in the elastic expansion and contraction of the spring 203, which is conducive to increasing the service life of the spring 203.

[0031] Among them, when the limiting block 202 is used to fix the glass tube through the limiting groove 4, there are two fixing points, which increases the limiting effect on the glass tube and improves the fixing effect of the device on the glass tube. The corners of the limiting block 202 are all set as rounded corners to avoid the corners of the limiting block 202 from causing damage to the glass tube, thereby improving the protection effect on the glass tube;

[0032] At the same time, the bolt 205 is adjusted by rotating the rotating block 5, and the resistance increasing strip 6 increases the friction between the hand and the rotating block 5, thereby improving the practicality during use;

[0033] In addition, the friction between the limit block 202 and the glass tube is increased by the resistance increasing layer 7, thereby improving the fixing effect on the glass tube.
