Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz capillary production technology, and in particular to a tooling for batch testing the geometric dimensions of quartz capillary tubes. Background Technology
[0002] Currently, capillary tubes produced by drawing towers on the market can produce 100 to 500 capillary tubes from a single mother tube, depending on the size. The production speed is generally 0.5 to 10 m / min, depending on the thickness. The high speed means that various factors can occur during the production process, making it impossible to guarantee that the size of the quartz capillary tubes produced is consistent. With a large daily output, quality inspection is a challenge. Each tube must be inspected for its geometric dimensions before being put into storage to ensure it is qualified. Data is accurately recorded by measuring the end face of each tube using a microscope.
[0003] Typically, one person can inspect about 50 to 80 pieces per day to check geometric dimensions. Each piece is cut into sections and placed on the inspection table for inspection, which is very inefficient.
[0004] The testing platform lacks suitable tooling for assisting in the testing of capillaries. Therefore, a tooling for batch fixing of capillaries to assist in testing is proposed. Utility Model Content
[0005] To address the aforementioned issues, a tooling solution for batch inspection of the geometric dimensions of quartz capillaries is provided, aiming to resolve the problems existing in the prior art.
[0006] The specific technical solution is as follows:
[0007] A geometric dimensioning fixture for batch testing of quartz capillaries includes a base, a placement platform, and a limiting member. The base has adjustable-length support legs at the four corners of its bottom surface. The placement platform is fixedly positioned at the center of the top surface of the base. The top surface of the placement platform has a V-shaped groove for inserting capillaries. The limiting member has guide posts at the four corners of its bottom surface. The lower ends of the four guide posts are respectively connected to the four corners of the top surface of the base, and the limiting member can move up and down along the guide posts.
[0008] The aforementioned quartz capillary batch inspection geometric dimension tooling also has the following feature: the bottom of each support foot is provided with a shock-absorbing rubber pad.
[0009] The aforementioned quartz capillary batch inspection geometric dimension fixture also has the following feature: the rear end of the V-groove is closed and the front end is open. When multiple capillaries are placed into the V-groove, the rear ends of all capillaries are flush and the front ends extend out of the V-groove.
[0010] The aforementioned quartz capillary batch inspection geometric dimension fixture also features a movable plate, a limiting body, and four locking rings. The movable plate has through holes at each of its four corners for the guide posts to pass through. The limiting body is located on the bottom surface of the movable plate. When the movable plate moves to its lowest position, the limiting body fits precisely against the top surface of the placement platform. The four locking rings are respectively fitted onto the four guide posts, and all four locking rings are connected to the top surface of the movable plate. When the locking rings are adjusted to the locked state, the movable plate is fixed at the corresponding height.
[0011] The aforementioned quartz capillary batch inspection geometric dimension fixture also has the following features: the locking collar includes a fixed body and a movable body. The fixed body and one end of the movable body are hinged together. The fixed body is connected to the movable plate. Grooves are provided on the side walls of both the fixed body and the movable body. Buckles are provided at the other ends of the fixed body and the movable body. When the movable body and the movable body are in contact with each other, the two grooves together form a channel through which the guide post can pass. At this time, the buckles can fix the fixed body and the movable body at the corresponding height of the guide post.
[0012] The aforementioned quartz capillary batch inspection geometric dimension fixture also has the following feature: an anti-slip pad is embedded in the groove, and the anti-slip pad is provided with several anti-slip ridges on the side facing the guide post.
[0013] The aforementioned quartz capillary batch inspection geometric dimension fixture also has the following feature: both the placement stage and the limiting body are made of polytetrafluoroethylene material to avoid scratching the capillary.
[0014] In summary, the beneficial effects of this scheme are:
[0015] The quartz capillary batch inspection geometric dimension fixture provided by this utility model allows for batch dimensional inspection of capillary tubes by placing the capillary tubes into multiple evenly arranged V-grooves and using a limiting component to press and limit all the capillary tubes. This fixture effectively enables batch fixing of capillary tubes for dimensional inspection. Attached Figure Description

Figure 3 This is a side view schematic diagram of the geometric dimension tooling for batch testing of quartz capillary tubes according to this utility model. Figure 4 This is a top view schematic diagram of the locking collar of the quartz capillary batch inspection geometric dimension tooling of this utility model, as shown below. Figures 1-4 As shown, the quartz capillary batch testing geometric dimension fixture provided in this embodiment includes a base, a placement platform 2, and a limiting member. Adjustable length support legs 11 are provided at the four corners of the bottom surface of the base. The placement platform 2 is fixedly set at the center of the top surface of the base. A V-shaped groove 21V for the capillary tube to be inserted is opened on the top surface of the placement platform 2. Guide posts 13 are provided at the four corners of the bottom surface of the limiting member. The lower ends of the four guide posts 13 are respectively connected to the four corners of the top surface of the base, and the limiting member can move up and down along the guide posts 13.
[0025] It should be noted that the base is made of high-strength aluminum alloy, and the surface is anodized or rust-proofed. The base is rectangular and flat to reduce the impact of external vibrations on the capillary.
[0026] It should also be noted that the placement platform 2 and the base are detachably connected.
[0027] In the above embodiments, shock-absorbing rubber pads 12 are provided at the bottom of each support leg 11.
[0028] In the above embodiment, the rear end of the V-groove 21V is closed and the front end is open. When multiple capillaries are placed into the V-groove 21V, the rear ends of all capillaries are flush and the front ends extend out of the V-groove 21V.
[0029] It should be noted that each placement platform 2 is provided with 20 V-shaped grooves 21V, and the fixed whole formed by the combination of multiple placement platforms 2 and limiting components can be stacked in multiple layers to further increase the fixing efficiency.
[0030] In the above embodiment, the device includes a movable plate 3, a limiting body 31, and four locking collars 32. The four corners of the movable plate 3 are provided with through holes through which the guide posts 13 can pass. The limiting body 31 is disposed on the bottom surface of the movable plate 3. When the movable plate 3 moves to the lowest position, the limiting body 31 fits exactly against the top surface of the placement platform 2. The four locking collars 32 are respectively sleeved on the four guide posts 13, and the four locking collars 32 are all connected to the top surface of the movable plate 3. When the locking collars 32 are adjusted to the locked state, the movable plate 3 is fixed at the corresponding height.
[0031] In the above embodiment, the locking collar 32 includes a fixed body 321 and a movable body 322. One end of the fixed body 321 and the movable body 322 are hinged together. The fixed body 321 is connected to the movable plate 3. Grooves are provided on the side walls of both the fixed body 321 and the movable body 322. Buckles 323 are provided on the other end of the fixed body 321 and the movable body 322. When the movable body 322 is in contact with each other, the two grooves together form a channel through which the guide post 13 can pass. At this time, the fixed body 321 and the movable body 322 can be fixed at the corresponding height of the guide post 13 by means of the buckle 323.
[0032] In the above embodiment, an anti-slip pad 324 is embedded in the groove, and the anti-slip pad 324 is provided with several anti-slip ridges on the side facing the guide post 13.
[0033] In the above embodiments, both the placement platform 2 and the limiting body 31 are made of polytetrafluoroethylene material to avoid capillary scratches.
[0034] The working principle is as follows: the movable plate 3 is driven to rise to a certain height, and then the locking ring 32 is used to fix it at the corresponding height. The capillary is placed into the V-groove 21V, and the rear end of the capillary is made to abut against the closed part of the rear end of the V-groove 21V. Before that, the front end of the capillary extends out of the V-groove 21V. The locking ring 32 is then unlocked, causing the movable plate 3 to descend until the limiting body 31 covers the placement stage 2. The locking ring 32 is then locked again to complete the fixation of the capillary. The end of the capillary extending out of the V-groove 21V can be inspected using a microscope.
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the content of the present utility model specification should be included within the protection scope of the present utility model.
