[0003] However, the limit movement slot is usually exposed, which makes it easy for dust to fall into its position. Because the gap is small, it is not easy to clean, and too much dust will seriously affect the operation of the machine.

[0004] This utility model addresses the aforementioned problems by providing an automatic centering mechanism for measuring the inner hole of a housing with a structure capable of shielding the movable slot. Utility Model Content

[0005] The main purpose of this invention is to address the problem that the limiting movement groove is usually exposed, making it easy for dust to fall into its position, and because its gap is small, it is not easy to clean. Excessive dust will seriously affect the operation of the machine.

[0006] To solve the above problems, this utility model proposes an automatic centering mechanism for measuring the inner hole of a housing, comprising: an automatic centering mechanism body and a limiting movement groove provided on the automatic centering mechanism body; The automatic centering mechanism has a horizontally moving plate located on its upper side. A telescopic connecting piece is provided at the middle position of the limiting moving groove, and a side connecting block is connected to the end of the telescopic connecting piece. A plug-in connecting post is provided at the side position of the side connecting block, and plug-in connecting grooves are provided on the side of the plug-in connecting post, both at the end of the limiting moving groove and on the horizontal moving plate.

[0007] In one embodiment, a vertical moving plate is provided on the upper side of the horizontal moving plate, and a driving element and a sensing element are provided on the vertical moving plate.

[0008] In one embodiment, a lifting head is connected to the upper side of the vertical moving plate, and the lifting head is driven to rise and fall by a cylinder in the vertical moving plate.

[0010] In one embodiment, a horizontally movable plate two is provided at the bottom side of the connecting sensor head, and a vertically movable plate two is provided at the upper side of the horizontally movable plate two. The vertically movable plate two is provided with a driving element and a sensing element.

[0011] In one embodiment, a lifting plate is connected to the upper side of the vertically moving plate two, and the lifting plate is driven to move up and down by a driving element of the vertically moving plate two.

[0012] In one embodiment, a drive-pressing limiting structure is connected to the upper side of the lifting plate, and the two drive-pressing limiting structures can move towards or away from each other along the lifting plate.

[0013] In one embodiment, a compression airbag layer is provided on the inner side of the driving compression limiting structure, a movable connecting piston is provided in the driving compression limiting structure, and a central connecting threaded post is provided on the side of the movable connecting piston.

[0014] In one embodiment, a connecting knob is provided at the end of the central connecting threaded post, and the outer side of the connecting knob is provided with texture.

[0015] In one embodiment, a side connecting through slot block is provided at the corner position of the automatic centering mechanism, and the side connecting through slot block is provided with a through slot.

[0016] Beneficial effects: 1. In the automatic centering mechanism for measuring the inner hole of the housing, a telescopic connecting piece is provided at the middle position of the limiting moving slot. The end of the telescopic connecting piece is connected to a side connecting block. A plug-in connecting post is provided on the side of the side connecting block. Plug-in connecting slots are also provided on the side of the plug-in connecting post, located at the end of the limiting moving slot and on the horizontal moving plate. Because the limiting moving slot is usually exposed, dust easily falls into it, and because the gap is small, it is not easy to clean. Excessive dust will seriously affect the operation of the machine. In this improved version, the telescopic connecting piece is installed and connected via a plug-in connection. The telescopic connecting piece can extend and retract with the operation of the connecting structure, and it can shield the limiting moving slot, thereby preventing dust from falling into the limiting moving slot to a certain extent. Moreover, the dust shielded on it is easy to clean, thus effectively improving the practicality of the automatic centering mechanism for measuring the inner hole of the housing.

A movable connecting piston is provided in the driving compression limiting structure, and a central connecting threaded column is provided on the side of the movable connecting piston. Because traditional limiting structures are usually rigid compression, their structure is usually fixed, making it difficult to adapt to housings of different shapes. After this improvement, the elastic material properties of the compression airbag layer can be used to adapt to housings of different shapes. Then, the rotation and movement of the central connecting threaded column pushes the movable connecting piston to compress the gas, thus stabilizing the compression of the compression airbag layer. After this improvement, the adaptability of the limiting structure of the automatic centering mechanism for measuring the inner hole of a housing can be effectively improved, thereby effectively improving the practicality of the automatic centering mechanism for measuring the inner hole of a housing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To achieve the above-mentioned utility model objectives, such as Figure 1-5 As shown, this utility model provides an automatic centering mechanism for measuring the inner hole of a housing, including: an automatic centering mechanism body 1 and a limiting moving groove 2 provided on the automatic centering mechanism body 1; The horizontally moving plate 3 is located on the upper side of the automatic centering mechanism body 1; A telescopic connecting piece 16 is provided at the middle position of the limiting moving groove 2. A side connecting block 17 is connected to the end of the telescopic connecting piece 16. A plug-in connecting post 18 is provided on the side of the side connecting block 17. Plug-in connecting grooves 19 are provided on the side of the plug-in connecting post 18, at the end of the limiting moving groove 2, and on the horizontal moving plate 3. Because the limiting moving groove 2 is usually exposed, dust can easily fall into it, and because the gaps are small, it is not easy to clean. Too much dust will seriously affect the operation of the machine. In this improved version, the telescopic connecting piece 16 is installed and connected by plug-in connection. The telescopic connecting piece 16 can extend and retract with the operation of the connecting structure. It can cover the limiting moving groove 2, thereby preventing dust from falling into the limiting moving groove 2 to a certain extent. The dust covered on it is easy to clean, thus effectively improving the practicality of the automatic centering mechanism for measuring the inner hole of the housing.

[0023] like Figure 1 As shown, a vertical moving plate 4 is provided on the upper side of the horizontal moving plate 3. A driving element and a sensing element are provided on the vertical moving plate 4. A lifting head 5 is connected to the upper side of the vertical moving plate 4. The lifting head 5 is driven to rise and fall by a cylinder in the vertical moving plate 4. In use, the horizontal moving plate 3 will move left and right along the limiting moving groove 2, and the vertical moving plate 4 can move back and forth along the horizontal moving plate 3 to adjust its position. The lifting head 5 can be driven by the vertical moving plate 4 to adjust its height.

[0024] like Figure 1 As shown, a probe rod 6 is provided at the front of the lifting head 5, and a connecting sensor head 7 is provided at the end of the probe rod 6. The connecting sensor head 7 can be moved to the center position of the inner hole of the housing under the action of the horizontal moving plate 3, the vertical moving plate 4 and the lifting head 5 to confirm the center coordinates of the inner hole of the housing.

[0025] like Figure 1 As shown, a horizontal moving plate 8 is provided at the bottom side of the sensor head 7, and a vertical moving plate 9 is provided above the horizontal moving plate 8. The vertical moving plate 9 contains a driving element and a sensing element. A lifting plate 11 is connected to the upper side of the vertical moving plate 9. The lifting plate 11 is driven to rise and fall by the driving element of the vertical moving plate 9. A driving compression limiting structure 10 is connected to the upper side of the lifting plate 11. The two driving compression limiting structures 10 can move towards or away from each other along the lifting plate 11. After the sensor head 7 confirms the center position of the inner hole of the housing, it will transmit data and reset to the middle position of the automatic centering mechanism 1. At the same time, it controls the horizontal moving plate 8, the vertical moving plate 9 and the lifting plate 11 to move so that the center of the inner hole of the housing is also in the middle position of the automatic centering mechanism 1, thereby realizing the automatic centering operation of the inner hole, which facilitates the measurement of the hole diameter.

A movable connecting piston 14 is provided in the driving compression limiting structure 10. A central connecting threaded post 13 is provided on the side of the movable connecting piston 14. Because traditional limiting structures are usually rigid compression, their structure is usually fixed, making it difficult to adapt to shells of different shapes. After the improvement of this utility model, the elastic material properties of the compression airbag layer 12 can be used to adapt to shells of different shapes. Then, the rotation and movement of the central connecting threaded post 13 pushes the movable connecting piston 14 to compress the gas, so that the compression airbag layer 12 is compressed stably. After the improvement of this utility model, the adaptability of the limiting structure of the automatic centering mechanism for measuring the inner hole of the shell can be effectively improved, thereby effectively improving the practicality of the automatic centering mechanism for measuring the inner hole of the shell.

[0027] like Figure 4 As shown, a connecting knob 15 is provided at the end of the central connecting threaded post 13. The outer side of the connecting knob 15 is textured. The texture on the outer side of the connecting knob 15 can increase the friction between the knob and the user's hand, thereby making it easier for the user to rotate the connecting knob 15 for adjustment.

[0028] like Figure 4 As shown, a side connecting slot block 20 is provided at the corner position of the automatic centering mechanism body 1. The side connecting slot block 20 is provided with a through slot.
