Description

Technical Field

[0001] This utility model relates to the field of gauge technology for measuring and controlling the parallelism of dual guide rails in oxygen chambers, specifically to gauges for controlling the parallelism of dual guide rails. Background Technology

[0002] In the structure of a low-pressure oxygen-enriched rigid oxygen chamber, the smooth operation of the door is directly related to the safety and reliability of the oxygen chamber. The doors of this type of oxygen chamber are usually equipped with double guide rails along the axial direction to achieve sliding opening and closing. The parallelism of the double guide rails is the core element to ensure the sliding quality of the door. If the parallelism deviation exceeds the allowable range, it will cause the door to jam, wear to increase, and may even cause safety hazards such as reduced sealing performance due to uneven force. Currently, existing instruments for measuring and controlling the parallelism of dual guide rails in oxygen chambers have many limitations. Firstly, dimensional deviations are inevitable during the manufacturing process of the oxygen chamber, and the curved structure of the chamber places special demands on the adaptability of measuring instruments. Conventional general-purpose measuring instruments are difficult to fit the installation environment of the chamber and guide rails, making operation easily constrained by space limitations and compromising measurement accuracy. Secondly, existing instruments are mostly designed with fixed dimensions, unable to flexibly adapt to the spacing adjustment requirements of dual guide rails in oxygen chambers of different specifications. During on-site assembly and debugging, frequent instrument changes or complex calculations are required, which not only reduces work efficiency but may also affect the parallelism control effect due to the cumulative error of multiple measurements. Therefore, it is urgent to design a gauge to control the parallelism of dual guide rails to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a gauge for controlling the parallelism of dual guide rails, so as to solve the above-mentioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A gauge for controlling the parallelism of dual guide rails includes a gauge main frame, one end of which has an insertion slot into which a gauge sub-frame is inserted. A manual lock nut is sleeved on one end of the gauge main frame, the inner diameter of which has an internal thread. The outer wall of the gauge sub-frame has an external thread, which engages with the internal thread. A positioning plate is provided on the outer wall of one end of both the gauge main frame and the gauge sub-frame.

[0005] In a preferred embodiment of this utility model, a limiting block is provided on the outer wall of one end of the gauge main frame, and a plurality of guide screws are provided on the inner wall of the outer wall of one end of the insertion groove on the gauge main frame.

[0006] In a preferred embodiment of this utility model, a guide groove is provided on the outer wall of the gauge subframe, and the guide screw is engaged in the guide groove.

[0007] In a preferred embodiment of this utility model, a limiting groove is formed in the inner diameter of the manual lock nut, a limiting block is engaged in the limiting groove, and a notch is formed on one side of the limiting groove on the manual lock nut, the size of the notch matching the direction of the limiting block.

[0008] In a preferred embodiment of this utility model, the outer wall of the manual lock nut is provided with anti-slip texture, and the protrusions in the anti-slip texture are diamond-shaped.

[0009] In a preferred embodiment of this utility model, one end face of the positioning plate is an arc-shaped groove.

[0010] In a preferred embodiment of this utility model, the guide screw surface is provided with a hexagonal screw hole, and the guide screw is threadedly connected to the gauge main frame.

[0011] In the above technical solution, the gauge for controlling the parallelism of the dual guide rails provided by this utility model has the following beneficial effects: (1) By setting up a manual lock nut and a gauge subframe, and a thread transmission structure of the manual lock nut and the external thread, it can flexibly adapt to double guide rails with different spacings. The positioning plate is designed as an arc groove, which can closely fit the arc surface of the oxygen chamber guide rail, solving the problem of inconvenient operation caused by the deviation of the chamber structure of traditional measuring tools, and facilitating quick installation and measurement on site.

[0012] (2) By setting guide screws and guide grooves, the gauge subframe is restricted to slide only along the axial direction, avoiding radial offset during adjustment and ensuring measurement accuracy. The manual lock nut achieves circumferential positioning through the cooperation of the limit groove and the limit block. When rotating, it can stably drive the subframe to move. With the anti-slip texture, the controllability of the adjustment process is improved and the slip error is reduced.

[0013] (3) By setting up a main gauge frame and a secondary gauge frame, the special gauge directly measures and adjusts the parallelism of the double guide rails, which can quickly identify deviations and guide corrections, avoiding problems such as door sliding jamming and poor sealing caused by excessive parallelism, significantly improving the assembly quality of the oxygen chamber door. At the same time, the integrated adjustment structure reduces the frequency of tool replacement, shortens the on-site debugging time, and improves work efficiency. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-6 As shown, the gauge for controlling the parallelism of the dual guide rails provided in this embodiment of the utility model includes a gauge main frame 1, one end of which is provided with an insertion groove 6, and a gauge sub-frame 2 is inserted into the insertion groove 6. A manual lock nut 3 is sleeved on one end of the gauge main frame 1, and the inner diameter of the manual lock nut 3 is provided with an internal thread 8. The outer wall of the gauge sub-frame 2 is provided with an external thread 10, and the external thread 10 and the internal thread 8 are threadedly engaged. A positioning plate 4 is provided on the outer wall of one end of both the gauge main frame 1 and the gauge sub-frame 2.

[0024] In this embodiment, the main gauge frame 1 has a slot 6 at one end, and the auxiliary gauge frame 2 is inserted into the slot 6. The slot 6 of the main gauge frame 1 and the auxiliary gauge frame 2 form a nested structure. With the thread transmission of the internal thread 8 of the manual lock nut 3 and the external thread 10 of the auxiliary frame, a precise length adjustment mechanism is formed. The manual lock nut 3 is sleeved at one end of the main gauge frame 1. The inner diameter of the manual lock nut 3 has an internal thread 8. The outer wall of the auxiliary gauge frame 2 has an external thread 10. The external thread 10 and the internal thread 8 are threadedly engaged. The outer wall of one end of both the main gauge frame 1 and the auxiliary gauge frame 2 is provided with a positioning plate 4 for positioning the position of the two parallel guide rails.

[0025] In this embodiment, a limit block 7 is provided on the outer wall of one end of the main gauge frame 1 to limit the axial displacement of the manual lock nut 3, and a number of guide screws 5 are provided on the outer wall of one end of the insertion groove 6 on the main gauge frame 1 to limit the radial rotation of the secondary gauge frame 2.

[0026] In this embodiment, a guide groove 11 is provided on the outer wall of the gauge sub-frame 2, and the guide screw 5 is engaged in the guide groove 11 to form a double guide constraint. On the one hand, it restricts the radial rotation of the gauge sub-frame 2 and ensures that the arc groove of the positioning plate 4 is always in contact with the guide rail during the extension and retraction process.

[0027] In this embodiment, a limiting groove 9 is provided on the inner diameter of the manual lock nut 3, and a limiting block 7 is engaged in the limiting groove 9. When the manual lock nut 3 is rotated, the limiting block 7 slides in the limiting groove 9, which restricts the axial displacement of the manual lock nut 3 and forces the gauge subframe 2 to extend and retract axially, thereby realizing stepless adjustment of the spacing between the positioning plates 4 and adapting to the measurement requirements of different specifications of dual guide rails. A notch 13 is provided on one side of the limiting groove 9 on the manual lock nut 3. The size of the notch 13 matches the direction of the limiting block 7, and the notch 13 ensures that the manual lock nut 3 can be installed and removed.

[0028] In this embodiment, the outer wall of the manual lock nut 3 is provided with anti-slip texture 12. The protrusions in the anti-slip texture 12 are diamond-shaped. The diamond-shaped anti-slip texture 12 increases the friction and can effectively prevent slipping.

[0029] In this embodiment, one end face of the positioning plate 4 is an arc-shaped groove, which matches the curved contour of the circular oxygen chamber guide rail, improving the fit and reducing the reading deviation caused by the measurement gap.

[0030] In this embodiment, the guide screw 5 has a hexagonal screw hole on its surface. The guide screw 5 is threadedly connected to the gauge main frame 1. The threaded connection between the guide screw and the main frame facilitates tool operation and allows for locking of the sub-frame position as needed, preventing errors caused by loosening during measurement.

[0031] Working steps: 1. Rotate the manual lock nut 3, and use the threaded engagement to drive the gauge sub-frame 2 to slide axially along the insertion slot 6 of the gauge main frame 1. At the same time, the guide screw 5 slides synchronously in the guide slot 11 until the distance between the two positioning plates 4 matches the distance between the double guide rails to be measured. 2. Secure the positioning plates 4 on the main frame 1 and the auxiliary frame 2 of the gauge to both sides of the double guide rail, so that the arc groove of the positioning plate 4 fits tightly with the surface of the guide rail, ensuring that the gauge and the double guide rail form a stable measurement posture. 3. Observe the fit between the two positioning plates 4 and the double guide rails. By judging the parallelism deviation of the double guide rails through the relative positional relationship between the main gauge frame 1 and the auxiliary gauge frame 2, adjust the installation position of the double guide rails according to the measurement results until their parallelism meets the tolerance requirements. 4. If it is necessary to maintain the current state of the gauge to assist in fixing the guide rail, the set screw can be tightened through the hexagonal screw hole on the surface of the guide set screw 5 to further restrict the sliding of the gauge sub-frame 2 and ensure the stability of the adjusted guide rail position.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
