Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a hole position detection and side plate position detection device. Background Technology

[0002] During the product manufacturing process, holes are usually machined on the product. It is often necessary to check the hole positions. For some products, it is also necessary to check the position of the side plate where the holes are located to ensure the product is qualified. In existing patents, the applicant filed a Chinese patent application on June 9, 2023, with application number 202321484849.1, disclosing a hole position detection mechanism. This mechanism includes a base, a fixed base, a guide sleeve, a hole position detection pin, an elastic element, a locking pin, and an offset detector. The base has a measuring space, the fixed base has an offset hole, a mounting hole, an insertion hole, and an offset slot. The offset slot penetrates the offset hole and the mounting hole, and communicates with the measuring space. The guide sleeve has an offset guide plate that slides within the offset slot. One end of the offset guide plate protrudes into the measuring space, and the offset guide plate has a locking hole. A locking pin is detachably inserted into the insertion hole and passes through the locking hole. The hole position detection pin slides through the inner hole of the guide sleeve, and the guide sleeve is movable within the offset hole. The hole position detection pin has a limiting ring, and the input end of the offset detector protrudes into the measuring space. While this patent can detect the offset of the hole position, it cannot detect the positional accuracy of the side plate where the hole is located. Therefore, its shortcomings are obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a hole position detection and side plate position detection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hole position detection and side plate position accuracy detection device includes a support base, a detection sleeve, a reference cylinder, a spring, a pin, a shaft, a reset ring, and a detection pin. The support base has a sleeve hole, through which the detection sleeve movably passes. A front limiting ring and a rear limiting ring are respectively provided at both ends of the detection sleeve. The front limiting ring abuts against the front side of the support base, and the rear limiting ring abuts against the rear side of the support base. A hole position detection gap exists between the outer wall of the detection sleeve and the inner wall of the sleeve hole. The shaft slides through the front limiting ring, the detection sleeve, and the rear limiting ring. The spring is sleeved outside the shaft, with one end of the spring engaging with the rear limiting ring. When the spring is extended, the other end of the spring extends into the reference cylinder and abuts against the bottom of the reference cylinder. The rear part of the shaft extends into the reference cylinder and is connected to the pin handle via a connector. The bottom of the reference cylinder is sandwiched between the pin handle and the shaft. The connector passes through the bottom of the reference cylinder. The open end face of the reference cylinder is used to abut against the rear limit ring. The reset ring is installed at the front part of the shaft. The detection pin is set at the front end face of the shaft. The middle of the detection pin is provided with a side plate position detection mark. When the spring is in the extended state, the open end face of the reference cylinder separates from the rear limit ring, and the reset ring abuts against the front end face of the detection sleeve.

[0006] Furthermore, the rear limit ring and the detection sleeve are integrated into one piece.

[0007] Furthermore, the front limit ring is detachably fitted onto the detection sleeve, and a slot is provided at the end of the detection sleeve away from the rear limit ring. A limit ring is detachably fitted into the slot, and the front limit ring is clamped between the limit ring and the front side of the support base.

[0008] Furthermore, the side plate position measurement mark is an annular groove formed by a recess in the middle circumference of the self-detection pin.

[0009] Furthermore, the inner wall of the annular groove is coated with a colored coating.

[0010] Furthermore, the support base is L-shaped, with a sleeve hole set in the vertical plate of the support base, and a fixing hole is opened in the horizontal plate of the support base.

[0011] Furthermore, the connector includes an end cap and a connecting rod connected to the end cap. The bottom of the reference cylinder has a through hole, and the rear end of the shaft has a connecting hole. The end face of the end cap abuts against the bottom of the reference cylinder. The connecting rod passes through the through hole and is inserted into the connecting hole. The end cap and the pin are detachably connected.

[0012] Furthermore, the connecting rod is a screw rod, the connecting hole is a screw hole, and the connecting rod is threadedly connected to the connecting hole.

[0013] Furthermore, the pin shank has an axial recessed fitting hole, into which the end cap is inserted.

[0014] Furthermore, the pin shank is radially recessed with a locking hole communicating with the fitting hole, and a locking fastener is detachably connected to the locking hole. The locking fastener is used to lock the end cap in the fitting hole of the pin shank.

[0015] The beneficial effects of this utility model are as follows: In practical applications, the product is fixed in a specific position so that the side plate of the product corresponds to this utility model, and the side plate of the product has a hole to be tested. Then, pressure is applied to the pin handle until the open end of the reference cylinder is pressed against the end face of the rear limiting ring and the spring is compressed. During this process, the testing sleeve can move relative to the support seat within the sleeve hole. When the testing pin can be inserted into the hole to be tested of the product, it proves that the hole position of the testing hole on the side plate of the product is qualified. When the testing pin is inserted into the hole to be tested of the product, and the side plate of the product is exactly located at the side plate position accuracy test mark of the testing pin, it proves that the position accuracy of the side plate on the product is qualified, thus proving that the product is qualified. When the testing pin cannot be inserted into the hole to be tested of the product even if it moves within the hole position detection gap range, it proves that the hole position of the product is unqualified. When the testing pin is inserted into the hole to be tested of the product, but the side plate of the product is not at the side plate position accuracy test mark of the testing pin, it proves that the position accuracy of the side plate of the product is deviated, and the position accuracy of the side plate of the product is unqualified. After the product inspection is completed, the force on the pin is released, the spring elastically recovers, and drives the reference cylinder to move backward. The backward movement of the reference cylinder drives the pin, shaft, and detection pin to move backward until the reset ring abuts against the front end face of the detection sleeve, thus achieving automatic reset of this invention and facilitating the inspection of the next product. This invention can not only detect the hole positions of the product, but also detect the positional accuracy of the side plate where the hole is located, thus achieving dual functionality.

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0021] like Figure 1 and Figure 2As shown, this utility model provides a hole position detection and side plate position measurement device, which includes a support base 1, a detection sleeve 2, a reference cylinder 3, a spring 4, a pin 5, a shaft 6, a reset ring 7, and a detection pin 8. The support base 1 has a sleeve hole, and the detection sleeve 2 movably passes through the sleeve hole. A front limiting ring 10 and a rear limiting ring 11 are respectively provided at both ends of the detection sleeve 2. The front limiting ring 10 abuts against the front side of the support base 1, and the rear limiting ring 11 abuts against the rear side of the support base 1. A hole position detection gap 12 is formed between the outer wall of the detection sleeve 2 and the inner wall of the sleeve hole. The shaft 6 slides through the front limiting ring 10, the detection sleeve 2, and the rear limiting ring 11. The spring 4 is sleeved outside the shaft 6, with one end of the spring 4 abutting against the rear limiting ring 11. One end extends into the reference cylinder 3 and abuts against the bottom of the reference cylinder 3. The rear part of the shaft 6 extends into the reference cylinder 3 and is connected to the pin handle 5 via the connector 17. The bottom of the reference cylinder 3 is sandwiched between the pin handle 5 and the shaft 6. The connector 17 passes through the bottom of the reference cylinder 3. The open end face of the reference cylinder 3 is used to abut against the rear limiting ring 11. The reset ring 7 is installed at the front part of the shaft 6. The detection pin 8 is set at the front end face of the shaft 6. The middle part of the detection pin 8 is provided with a side plate position detection mark 13. When the spring 4 is in the extended state, the open end face of the reference cylinder 3 separates from the rear limiting ring 11, and the reset ring 7 abuts against the front end face of the detection sleeve 2. The detection sleeve 2 is limited in the sleeve hole of the support seat 1 by the front limiting ring 10 and the rear limiting ring 11.

[0022] In practical applications, product 24 is fixed in a specific position so that the side plate 25 of product 24 corresponds to this utility model, and the side plate 25 of product 24 has a hole to be tested. Then, pressure is applied to the pin handle 5 until the open end of the reference cylinder 3 is pressed against the end face of the rear limiting ring 11 and the spring 4 is compressed. During this process, since there is a hole position detection gap 12 between the outer wall of the detection sleeve 2 and the inner wall of the sleeve hole, and the support seat 1 is clamped between the front limiting ring 10 and the rear limiting ring 11, the detection sleeve 2 can move relative to the support seat 1 in the sleeve hole. When the detection pin 8 can be inserted into the hole to be tested of product 24, it proves that the hole position of the detection hole on the side plate 25 of product 24 is qualified. When the detection pin 8 is inserted into the hole to be tested of product 24, and the side plate 25 of product 24 is just located at the side plate position degree detection mark 13 of the detection pin 8, it proves that the position degree of the side plate 25 on product 24 is qualified, thus proving that product 24 is qualified. When the detection pin 8 cannot be inserted into the hole to be tested in product 24 within the hole detection gap 12, it proves that the hole position of product 24 is unqualified. When the detection pin 8 is inserted into the hole to be tested in product 24, but the side plate 25 of product 24 is not at the side plate position measurement mark 13 of the detection pin 8, it proves that the position of the side plate 25 of product 24 is deviated, and the position of the side plate 25 of product 24 is unqualified. After the product 24 is tested, the force on the pin handle 5 is released, the spring 4 elastically recovers and drives the reference cylinder 3 to move backward. The backward-moving reference cylinder 3 drives the pin handle 5, the shaft 6 and the detection pin 8 to move backward until the reset ring 7 abuts against the front end face of the detection sleeve 2, so as to realize the automatic reset of this utility model, thereby facilitating the testing of the next product 24. This utility model can not only detect the hole position of product 24, but also detect the position of the side plate 25 where the hole is located, so as to realize two uses in one device.

[0023] In this embodiment, the rear limiting ring 11 and the detection sleeve 2 are integrally constructed, which makes the connection between the rear limiting ring 11 and the detection sleeve 2 firm.

[0024] In this embodiment, the front limiting ring 10 is detachably fitted onto the detection sleeve 2. A slot 14 is provided at the end of the detection sleeve 2 furthest from the rear limiting ring 11, and a limiting ring 15 is detachably fitted into the slot 14. The front limiting ring 10 is sandwiched between the limiting ring 15 and the front side of the support base 1. This structural design not only facilitates the assembly and disassembly of the detection sleeve 2 and the support base 1, but also ensures that the detection sleeve 2 can move within the sleeve hole of the support base 1.

[0025] In this embodiment, the side plate position detection mark 13 is an annular groove recessed into the center periphery of the detection pin 8. When the side plate 25 of the product 24 is located in the annular groove, it proves that the position of the side plate 25 of the product 24 is qualified; the setting of the annular groove makes it convenient for operators to judge the position of the side plate 25 of the product 24.

[0026] In this embodiment, the inner wall of the annular groove is coated with a color coating. The color coating allows the operator to quickly determine whether the position of the side plate 25 of the end product 24 is qualified.

[0027] In this embodiment, the support base 1 is L-shaped, with a sleeve hole in the vertical plate of the support base 1, and a fixing hole 16 is provided in the horizontal plate of the support base 1. In practical applications, screws are threaded into the fixing hole 16 and then into the external structure to lock the support base 1 onto the external structure.

[0028] In this embodiment, the connector 17 includes an end cap 18 and a connecting rod 19 connected to the end cap 18. A through hole 20 is provided at the bottom of the reference cylinder 3, and a connecting hole 21 is recessed at the rear end of the shaft 6. The end face of the end cap 18 abuts against the bottom of the reference cylinder 3. The connecting rod 19 passes through the through hole 20 and is inserted into the connecting hole 21. The end cap 18 is detachably connected to the pin shank 5. This structural design facilitates the connector 17 in connecting the pin shank 5, the reference sleeve, and the shaft 6 together.

[0029] In this embodiment, the connecting rod 19 is a screw rod, and the connecting hole 21 is a screw hole, with the connecting rod 19 and the connecting hole 21 being threaded together. This structural design ensures a firm connection between the connecting rod 19 and the shaft 6, and facilitates the assembly and disassembly of the connecting piece 17 and the shaft 6.

[0030] In this embodiment, the pin shank 5 is axially recessed with a fitting hole 22, and the end cap 18 is inserted into the fitting hole 22. This structural design facilitates the assembly of the pin shank 5 and the end cap 18 of the connector 17.

[0031] In this embodiment, the pin shank 5 has a radially recessed locking hole 23 communicating with the mounting hole 22. A locking fastener is detachably connected to the locking hole 23, and the fastener is used to lock the end cap 18 within the mounting hole 22 of the pin shank 5. Specifically, the locking hole 23 is a threaded hole, and the fastener is a locking bolt. The stud of the locking bolt is threaded into the threaded hole, and the end face of the stud of the locking bolt abuts against the peripheral wall of the end cap 18. During assembly, the end cap 18 is inserted into the mounting hole 22 of the pin shank 5, and the fastener in the locking hole 23 is tightened, so that the fastener locks the end cap 18 within the mounting hole 22 of the pin shank 5. When it is necessary to disassemble the pin shank 5, the fastener is loosened, causing the fastener to release the end cap 18, at which point the pin shank 5 and the connector 17 can be removed.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
