Description

Technical Field

[0001] This utility model relates to the field of quartz air inlet pipe technology, and in particular to a tooling for measuring the dimensions of quartz air inlet pipes. Background Technology

[0002] A quartz inlet tube is a tubular device made of quartz glass, primarily used for conveying gases in experimental and industrial environments requiring high temperatures, strong corrosiveness, or high purity. Its core characteristics include high temperature resistance, chemical inertness, high light transmittance (ultraviolet to infrared band), and a low coefficient of thermal expansion. During the production of quartz inlet tubes, dimensional inspection fixtures are typically used to check their dimensions.

[0003] When using a dimensional inspection fixture to inspect the dimensions of a quartz air inlet tube, two sets of adjustment mechanisms are typically used to move the clamping plate to facilitate the inspection of the length and diameter of the quartz air inlet tube. However, these two sets of adjustment mechanisms usually require two sets of drive mechanisms, which results in resource waste, higher costs, and is not conducive to the use of the dimensional inspection fixture. Utility Model Content

Moreover, only one set of driving mechanism is needed for use, saving resources and costs, and achieving the purpose of conveniently detecting the length and diameter of quartz inlet tubes.

[0022] Example: Refer to Figure 1-6 This utility model provides a technical solution for a quartz inlet pipe dimensional inspection fixture, including a worktable 1. A first support block 20 and a second support block 21 are fixedly installed on the top of the worktable 1. The first support block 20 and the second support block 21 are on the same axis. A connecting plate 5 is installed on one side of the worktable 1 via a moving mechanism. A first bevel gear 10 is also fixedly installed on one side of the worktable 1 via the moving mechanism. The moving mechanism includes a motor 2 fixedly installed on one side of the worktable 1. A lead screw 3 is fixedly installed at the output end of the motor 2. A first moving block 4 is threaded onto the surface of the lead screw 3. The top of the first moving block 4 and the bottom of the connecting plate 5 are fixedly installed, facilitating... The connecting plate 5 is moved by the screw 3. One end of the screw 3 is fixedly installed on one side of the first bevel gear 10 to facilitate the rotation of the first bevel gear 10. The top of the worktable 1 is provided with a first slide groove 18. The inner wall of the first slide groove 18 is in contact with the surface of the first moving block 4 to limit the movement of the first moving block 4, making the movement of the first moving block 4 more stable. A telescopic rod 6 and a spring 7 are fixedly installed on one side of the connecting plate 5. A first clamping plate 8 is fixedly installed on one end of the spring 7. A blocking plate 22 is fixedly installed on the top of the worktable 1. One side of the blocking plate 22 cooperates with one side of the first clamping plate 8. A first pointer 9 is fixedly installed on one side of the first clamping plate 8.

[0023] Specifically, a second bevel gear 11 is meshed with the surface of the first bevel gear 10. A second clamping plate 14 is installed on the inner wall of the second bevel gear 11 via an adjustment mechanism. The adjustment mechanism includes a bidirectional threaded rod 12 fixedly installed on the inner wall of the second bevel gear 11. A second moving block 13 is threadedly fitted onto the surface of the bidirectional threaded rod 12. The top of the second moving block 13 and the bottom of the second clamping plate 14 are fixedly installed to facilitate the movement of the second clamping plate 14. There are two sets of second moving blocks 13 and second clamping plates 14, which are symmetrically arranged. A second sliding groove 19 is provided on the top of the worktable 1. The inner wall of the second sliding groove 19 is in contact with the surface of the second moving block 13 to limit the movement of the second moving block 13, making the movement of the second moving block 13 more stable. A second pointer 15 is fixedly installed on one side of the second clamping plate 14. A first scale line 16 and a second scale line 17 are provided on the top of the worktable 1. The first clamping plate 8 is moved by a moving mechanism, which, together with the blocking plate 22, clamps both ends of the quartz air inlet tube. The length of the quartz air inlet tube can be determined by the position of the first pointer 9 pointing to the first scale line 16. The second clamping plate 14 is moved in the opposite direction by an adjusting mechanism, which clamps the surface of the quartz air inlet tube. The diameter of the quartz air inlet tube can be determined by the position of the second pointer 15 pointing to the second scale line 17. At the same time, when the second clamping plate 14 moves, the connecting plate 5 can move under the action of the spring 7 while the position of the first clamping plate 8 does not move. This allows for the detection of quartz air inlets of different lengths and diameters. Moreover, only one set of driving mechanism is needed, saving resources and costs. It achieves the purpose of conveniently detecting the length and diameter of quartz air inlets. The structure is simple and easy to use.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0025] In use: When using this quartz air inlet tube dimensional inspection fixture, the quartz air inlet tube is placed on the inner wall of the first support block 20 and the second support block 21. The motor 2 drives the lead screw 3 to rotate, which in turn drives the first moving block 4 to move. The first moving block 4 then drives the connecting plate 5 to move, and the connecting plate 5 then drives the first clamping plate 8 to move. The first clamping plate 8 and the blocking plate 22 work together to clamp both ends of the quartz air inlet tube. The length of the quartz air inlet tube can be determined by the first pointer 9 pointing to the first scale line 16. Simultaneously, the lead screw 3 drives the first bevel gear 10 to rotate, which in turn drives the second bevel gear 11 to rotate. The second bevel gear 11 then drives the bidirectional threaded rod 12 to rotate, which in turn drives the two sets of second moving blocks 13 to move in opposite directions. The moving block 13 drives the second clamping plate 14 to move in opposite directions, thus clamping the surface of the quartz air inlet tube. The diameter of the quartz air inlet tube can be determined by the second pointer 15 pointing to the second scale line 17. At the same time, when the second clamping plate 14 moves, the connecting plate 5 can move under the action of the spring 7 while the position of the first clamping plate 8 does not move. This allows for the detection of quartz air inlets of different lengths and diameters. Only one set of drive mechanism is needed, saving resources and costs. It achieves the purpose of conveniently detecting the length and diameter of the quartz air inlet tube. The structure is simple and easy to use. After the detection is completed, the motor 2 drives the first clamping plate 8 to release the quartz air inlet tube. At the same time, the bidirectional threaded rod 12 drives the two sets of second clamping plates 14 to release the quartz air inlet tube, so that the quartz air inlet tube can be removed.
