Description

Technical Field

[0001] This utility model relates to the field of positional accuracy detection technology, and in particular to a hemispherical hole positional accuracy detection device. Background Technology

[0002] In product manufacturing, holes are typically machined onto the product. To ensure the holes meet quality standards, their positional accuracy needs to be checked. Existing patents disclose various devices for hole positional accuracy detection. For example, Chinese patent application number 202021571516.9 discloses a device for checking hole positional accuracy and errors; Chinese patent application number 202320075690.1 discloses a hole position detection mechanism; and Chinese patent application number 202321484849.1 discloses a hole position detection mechanism. While these patents can detect the positional accuracy of holes, they cannot accurately detect the positional accuracy of hemispherical holes. Therefore, the 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 hemispherical hole position detection device.

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

[0005] A hemispherical hole position accuracy testing device includes a fixed base, a guide base, a T-shaped guide sleeve, a guide rod, an elastic element, a hemispherical head, a limiting rod, and a go / no-go gauge. The fixed base has an axially formed position accuracy testing hole, and a side plate of the fixed base has an insertion hole communicating with the position accuracy testing hole. The go / no-go gauge extends into the position accuracy testing hole through the insertion hole. The guide base is mounted on the top end face of the fixed base. The guide base has a T-shaped displacement hole and a lower displacement hole connected from top to bottom. The lower displacement hole is coaxially connected with the position accuracy testing hole. The T-shaped guide sleeve is mounted on the T-shaped displacement hole. The T-shaped guide sleeve can move within the T-shaped displacement hole. The top of the T-shaped guide sleeve extends out of the T-shaped displacement hole. The guide rod passes through the inner hole of the T-shaped guide sleeve and the lower displacement hole and then extends into the position detection hole. The guide rod can move within the lower displacement hole. The hemispherical head is installed at the top of the limiting rod. The elastic element is elastically clamped between the bottom surface of the hemispherical head and the top surface of the T-shaped guide sleeve. The top of the T-shaped guide sleeve has a radially opening lifting through hole. The limiting rod is vertically installed on the guide rod and passes through the lifting through hole. The limiting rod can move up and down within the lifting through hole.

[0006] Furthermore, the elastic element is a spring, which is sleeved on the outside of the guide rod.

[0007] Furthermore, the guide rod has a radially protruding hole, and the limiting rod is inserted through the hole.

[0008] Further, the alignment seat includes an alignment main body disposed on the top port surface of the fixed seat and a cover plate disposed on the top surface of the alignment main body. A circular hole is formed in the middle of the cover plate, a square groove communicating with the circular hole is recessed on the top surface of the alignment main body, and a downward displacement hole is recessed from the bottom wall of the square groove. The cover plate covers the top port of the square groove, and the circular hole and the square groove form a T-shaped displacement hole.

[0009] Further, the number of the insertion holes is two, and the two insertion holes are respectively disposed on two adjacent side plates of the fixed seat, and the two insertion holes are vertically arranged.

[0010] The beneficial effects of the present utility model: In practical applications, the fixed seat is fixedly installed on an external structure, the product is placed on the fixture, and the fixture clamps the product. The hemispherical head is pushed upward into the hemispherical hole of the product under the elastic force of the elastic member. When the hemispherical hole of the product and the hemispherical head are not exactly aligned, the arc surface of the hemispherical hole guides and presses the hemispherical head, causing the hemispherical head to compress the elastic member. Under the action of the arc surface of the hemispherical hole and the elastic force of the elastic member, the hemispherical head can move the guide rod and the T-shaped guide sleeve relative to the fixed seat and the alignment seat, that is, the T-shaped guide sleeve can move in the T-shaped displacement hole, and the guide rod can move in the downward displacement hole and the position tolerance detection hole until the hemispherical head is completely inserted into the hemispherical hole of the product, and the hemispherical head and the hemispherical hole are in concave-convex fit. At this time, the minimum tolerance end and the maximum tolerance end of the go-no-go gauge are sequentially inserted into the insertion holes. When the minimum tolerance end of the go-no-go gauge can pass through the insertion hole and be inserted into the position tolerance detection hole, and the maximum tolerance end of the go-no-go gauge cannot pass through the insertion hole and be inserted into the position tolerance detection hole, it proves that the position tolerance of the hemispherical hole of the product is qualified. If the minimum tolerance end of the go-no-go gauge cannot pass through the insertion hole and be inserted into the position tolerance detection hole or the maximum tolerance end of the go-no-go gauge can pass through the insertion hole and be inserted into the position tolerance detection hole, it proves that the position tolerance of the hemispherical hole of the product is unqualified. When the product is taken away, the hemispherical head and the guide rod can move upward and reset under the restoring force of the elastic member, so as to facilitate the position tolerance detection of the hemispherical hole of the next product. The limiting rod moves up and down in the lifting through hole, which improves the stability and position accuracy of the synchronous lifting of the hemispherical head and the limiting rod, and can also prevent the guide rod from separating from the T-shaped guide sleeve. The present utility model can detect the position tolerance of the hemispherical hole of the product to determine whether the position tolerance of the hemispherical hole of the product is qualified.

[0015] 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.

[0016] like Figure 1 and Figure 2 As shown, this utility model provides a hemispherical hole position measurement device, which includes a square fixed base 1, a guide base 2, a T-shaped guide sleeve 3, a guide rod 4, an elastic element 5, a hemispherical head 6, a limiting rod 7, and a go / no-go gauge 8. The fixed base 1 has an axially formed position measurement hole 9, which is a square hole. The side plate of the fixed base 1 has an insertion hole 10 communicating with the position measurement hole 9. The go / no-go gauge 8 extends into the position measurement hole 9 through the insertion hole 10. The guide base 2 is installed on the top end face of the fixed base 1. The guide base 2 has a T-shaped displacement hole 11 and a lower displacement hole 12 connected from top to bottom. The lower displacement hole 12 is coaxially connected with the position measurement hole 9. T-shaped guide sleeve 3 is installed inside T-shaped displacement hole 11. T-shaped guide sleeve 3 can move inside T-shaped displacement hole 11. The top of T-shaped guide sleeve 3 extends out of T-shaped displacement hole 11. Guide rod 4 passes through the inner hole of T-shaped guide sleeve 3 and lower displacement hole 12 and then extends into position detection hole 9. Guide rod 4 can move inside lower displacement hole 12. Hemispherical head 6 is installed at the top of limiting rod 7. Elastic element 5 is elastically clamped between the bottom surface of hemispherical head 6 and the top surface of T-shaped guide sleeve 3. The top of T-shaped guide sleeve 3 has a radially opening lifting through hole 13. Limiting rod 7 is vertically installed on guide rod 4. Limiting rod 7 passes through lifting through hole 13. Limiting rod 7 can move up and down inside lifting through hole 13.

[0017] In practical applications, the fixed base 1 is fixedly installed on the external structure. The product 16 is placed on the clamp, which clamps the product 16. Under the elastic force of the elastic element 5, the hemispherical head 6 pushes upward into the hemispherical hole of the product 16. When the hemispherical hole of the product 16 and the hemispherical head 6 are not perfectly aligned, the arc surface of the hemispherical hole guides and compresses the hemispherical head 6, causing the hemispherical head 6 to compress the elastic element 5. Under the action of the arc surface of the hemispherical hole and the elastic force of the elastic element 5, the hemispherical head 6, together with the guide rod 4 and the T-shaped guide sleeve 3, can move relative to the fixed base 1 and the guide seat 2. That is, the T-shaped guide sleeve 3 can move in the T-shaped displacement hole 11, and the guide rod 4 can move within the lower displacement hole 12 and the position detection hole 9. Until the hemispherical head 6 is fully inserted into the hemispherical hole of product 16, and the hemispherical head 6 and the hemispherical hole are properly fitted, the minimum tolerance end and the maximum tolerance end of the go / no-go gauge 8 are then inserted into the insertion hole 10 in sequence. When the minimum tolerance end of the go / no-go gauge 8 can be inserted into the position measurement hole 9 through the insertion hole 10, and the maximum tolerance end of the go / no-go gauge 8 cannot be inserted into the position measurement hole 9 through the insertion hole 10, it proves that the position of the hemispherical hole of product 16 is qualified. If the minimum tolerance end of the go / no-go gauge 8 cannot be inserted into the position measurement hole 9 through the insertion hole 10, or the maximum tolerance end of the go / no-go gauge 8 can be inserted into the position measurement hole 9 through the insertion hole 10, it proves that the position of the hemispherical hole of product 16 is unqualified. After product 16 is removed, the hemispherical head 6 and the guide rod 4 can move upward and reset under the action of the elastic force of the elastic element 5, so as to facilitate the position measurement of the hemispherical hole of the next product 16. The limiting rod 7 moves up and down within the lifting through hole 13, improving the stability and positional accuracy of the synchronous lifting of the hemispherical head 6 and the limiting rod 7, and also preventing the guide rod 4 from separating from the T-shaped guide sleeve 3. This utility model can detect the positional accuracy of the hemispherical hole of the product 16 to determine whether the positional accuracy of the hemispherical hole of the product 16 is qualified.

[0018] In this embodiment, the elastic element 5 is a spring, which is sleeved on the guide rod 4. The guide rod 4 guides and positions the elastic element 5, improving its operational stability.

[0019] In this embodiment, the guide rod 4 has a radially protruding insertion hole, and the limiting rod 7 is inserted through the insertion hole. This structural design facilitates the assembly and disassembly of the guide rod 4 and the limiting rod 7, thereby facilitating the assembly and disassembly of the guide rod 4, the elastic element 5, and the T-shaped guide sleeve 3.

[0020] In this embodiment, the guide seat 2 includes a guide body 14 mounted on the top end face of the fixed seat 1 and a cover plate 15 mounted on the top surface of the guide body 14. A circular hole is formed in the center of the cover plate 15. A square groove communicating with the circular hole is recessed on the top surface of the guide body 14. A lower displacement hole 12 is recessed from the bottom wall of the square groove. The cover plate 15 covers the top end of the square groove, and the circular hole and the square groove form a T-shaped displacement hole 11. This structural design enables modular assembly of the guide seat 2, facilitating easy disassembly and assembly, and also making it easier to process and form the T-shaped displacement hole 11 and the lower displacement hole 12.

[0021] In this embodiment, there are two insertion holes 10, which are respectively provided on two adjacent side plates of the fixing base 1 and are vertically arranged. By providing two insertion holes 10, it is convenient for operators to detect the position of the hemispherical hole of the product 16.

[0022] All technical features in this embodiment can be freely combined according to actual needs.

[0023] 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.
