Description

Technical Field

[0001] This utility model relates to the technical field of detecting the height of the inner flange of cylindrical parts, and in particular to a detection device that can quickly detect the height of the inner flange of cylindrical parts. Background Technology

[0002] The structure of cylindrical parts produced in a certain production workshop is as follows: Figures 1-2 As shown, the cylindrical part includes a cylindrical shell 1, which is only 4mm long, has an inner diameter of 2mm, and a wall thickness of 1mm. An annular inner flange 2 is fixedly provided inside the left opening of the cylindrical shell 1. The annular inner flange 2 is integrally formed with the inner wall of the cylindrical shell 1. Both the cylindrical shell 1 and the annular inner flange 2 are made of metal. This type of cylindrical part is mainly supplied to customers.

[0003] When a batch of such products is produced in the workshop Figures 1-2 After the cylindrical parts shown, and before supplying them to the customer, the technicians in the workshop are required to inspect the height H of the annular inner flange 2 of each cylindrical part, and reject the unqualified products whose height H does not meet the requirements, while put the qualified products whose height H meets the requirements into the finished product basket.

[0004] Because the annular inner flange 2 of the cylindrical part is located inside the cylindrical shell 1, and the inner diameter of the cylindrical shell 1 is quite small, it is impossible for workers to use vernier calipers [because the measuring rod of the vernier caliper cannot be inserted into the cylindrical shell 1]. Therefore, the existing technology in the workshop cannot measure the height of the annular inner flange 2.

[0005] Therefore, there is an urgent need for a detection device that can detect the height of the inner flange of cylindrical parts. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a detection device that can quickly detect the inner flange height of cylindrical parts.

[0007] The purpose of this utility model is achieved through the following technical solution: a detection device for quickly detecting the inner flange height of cylindrical parts, which includes a base plate, a rectangular block fixed on the top surface of the base plate and a strip-shaped fixing seat. The strip-shaped fixing seat is located on the right side of the rectangular block. A horizontally arranged through hole is opened in the strip-shaped fixing seat. A movable column head is slidably installed in the left port of the through hole. The left end of the movable column head extends outside the strip-shaped fixing seat, and a boss is fixed on the extended end. A thin rod is fixed on the left end face of the boss.

[0008] A guide sleeve is fixed inside the right port of the through hole. A pull rod is slidably installed in the center hole of the guide sleeve. The right end of the pull rod extends outside the strip-shaped fixing seat, and the left end of the pull rod extends inside the strip-shaped fixing seat and is detachably connected to the strip-shaped fixing seat. A spring is sleeved on the pull rod. The left end of the spring is fixed to the right end face of the movable column head, and the other end is fixed to the left end face of the guide sleeve. Under the elastic force of the spring, the thin rod abuts against the right end face of the rectangular block.

[0009] The rectangular block is detachably connected to the base plate via locking screws.

[0010] A ring-shaped pull plate is fixed to the right end of the pull rod.

[0011] The left end of the pull rod has an external thread on its cylindrical surface, and the right end face of the movable head has a threaded hole arranged along its axial direction. The external thread of the pull rod is threadedly connected to the threaded hole of the movable head.

[0012] The tie rod, movable column head, and thin rod are arranged coaxially.

[0013] The diameter of the thin rod is equal to the inner diameter of the cylindrical shell of the cylindrical part, and its length is greater than the length of the cylindrical shell.

[0014] This utility model has the following advantages:

[0015] The worker only needs to pull the annular plate to the right once, then place the cylindrical part onto the thin rod, and then release the annular plate so that the left end face of the cylindrical part abuts against the right end face of the rectangular block. The height L can then be measured. Finally, subtracting L from L gives the final detection of the height of the annular inner flange. Therefore, this detection device can detect the height of the inner flange of cylindrical parts, solving a long-standing technical challenge. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0032] like Figures 3-7 As shown, a detection device for quickly detecting the inner flange height of cylindrical parts includes a base plate 3, a rectangular block 4 fixed to the top surface of the base plate 3, and a strip-shaped fixing seat 5. The rectangular block 4 is detachably connected to the base plate 3 by a locking screw 13. The strip-shaped fixing seat 5 is located on the right side of the rectangular block 4. A horizontally arranged through hole 6 is opened in the strip-shaped fixing seat 5. A movable column head 7 is slidably installed in the left port of the through hole 6. The left end of the movable column head 7 extends outside the strip-shaped fixing seat 5, and a boss 8 is fixed on the extended end. A thin rod 9 is fixed on the left end face of the boss 8. The diameter of the thin rod 9 is equal to the inner diameter of the cylindrical shell 1 of the cylindrical part, and its length is greater than the length of the cylindrical shell 1.

[0033] A guide sleeve 10 is fixedly installed inside the right port of the through hole 6. A pull rod 11 is slidably installed inside the central hole of the guide sleeve 10. The pull rod 11, the movable column head 7, and the thin rod 9 are coaxially arranged. The right end of the pull rod 11 extends outside the strip-shaped fixing seat 5 and is fixedly connected to an annular pull plate 14. The left end of the pull rod 11 extends inside the strip-shaped fixing seat 5 and is detachably connected to the strip-shaped fixing seat 5. A spring 12 is sleeved on the pull rod 11. The left end of the spring 12 is fixed to the right end face of the movable column head 7, and the other end is fixed to the left end face of the guide sleeve 10. Under the elastic force of the spring 12, the thin rod 9 abuts against the right end face of the rectangular block 4.

[0034] The left end of the pull rod 11 has an external thread on its cylindrical surface, and the right end face of the movable head 7 has a threaded hole 15 arranged along its axial direction. The external thread of the pull rod 11 is threadedly connected to the threaded hole 15 of the movable head 7.

[0035] The working process of this utility model is as follows:

[0036] S1. The worker first uses a vernier caliper to measure the horizontal distance between the right end face of the rectangular block 4 and the left end face of the boss 8, and records it as L.

[0037] S2. The specific steps for detecting the height of the annular inner flange 2 of the first cylindrical part are as follows:

[0038] S21. The worker pulls the annular pull plate 14 to the right with his right hand. The annular pull plate 14 drives the pull rod 11 to move to the right. The pull rod 11 drives the movable column head 7 to move to the right. The movable column head 7 drives the boss 8 and the thin rod 9 to move to the right simultaneously. Figure 8 As shown, at the same time, the movable column head 7 compresses the spring 12 to the right. When the thin rod 9 moves away from the rectangular block 4, the worker stops pulling the annular pull plate 14 and keeps the annular pull plate 14 stationary.

[0039] S22. The worker uses his left hand to take out a sample to be tested. Figures 1-2 The cylindrical part shown is fitted onto the thin rod 9 from left to right with its cylindrical outer shell 1. Figures 9-10 As shown, the worker then releases the annular pull plate 14. At this time, under the elastic restoring force of the spring 12, the movable column head 7 drives the boss 8 and the thin rod 9 to move synchronously to the left. The thin rod 9 drives the cylindrical part sleeved on it to move synchronously to the left. Finally, the left end face of the cylindrical part's cylindrical shell 1 abuts against the right end face of the rectangular block 4, as shown. Figures 11-12 As shown;

[0040] S23. The worker used a vernier caliper to measure the distance between the right end face of the rectangular block 4 and the left end face of the boss 8, and recorded it as L1.

[0041] S24. The worker subtracts L from L1, and the calculated difference is the height of the inner flange of the cylindrical part. If the height does not meet the design requirements, the worker determines that the cylindrical part being inspected is a defective product; if the height meets the design requirements, the worker determines that the cylindrical part being inspected is a qualified product. The inspection of the height of the inner flange 2 of the first cylindrical part.

[0042] S3. Removal of non-conforming or conforming products: The worker pulls the annular pull plate 14 to the right, causing the thin rod 9 to move to the right. The thin rod 9 moves the non-conforming or conforming products to the right; then the worker removes the non-conforming or conforming products from the thin rod 9.

[0043] S4. Workers can repeat steps S2 to S3 multiple times to check the height of the annular inner flange 2 of all cylindrical parts.

[0044] As shown in step S2, the worker only needs to pull the annular pull plate 14 to the right once, then place the cylindrical part on the thin rod 9, and then release the annular pull plate 14 so that the left end face of the cylindrical part abuts against the right end face of the rectangular block 4. L1 can then be measured. Finally, L is subtracted from L1 to determine the height of the annular inner flange 2. Therefore, this detection device can detect the height of the inner flange of cylindrical parts, solving a long-standing technical difficulty.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
