Description

Technical Field

[0001] This utility model relates to the field of rotating shaft technology, specifically to a damping rotating shaft structure for an operating box. Background Technology

[0002] The machine tool control panel is the main device used for direct operation of a machine tool, often referred to as a machine-side control panel. It consists of a panel, controller, buttons, switches, etc., allowing for convenient and quick operation of various functions, parameter settings, and monitoring of the machine tool's operating status even during downtime.

[0003] The main function of the machine tool control panel is to control and manage the machine tool, including parameter setting and monitoring of its operating status. By understanding the meaning of each letter in the control panel, the operator can effectively control the machine tool's operating status and adjust parameters according to processing requirements, thereby improving the machine tool's processing efficiency and quality.

[0004] The machine tool control box has many internal structural components, including the use of a rotating shaft structure. However, when the traditional rotating shaft structure is used in the control box, it is inconvenient to position and lock the internal rotating structure of the shaft, which cannot meet more work requirements and has certain limitations. Therefore, this utility model proposes a damped rotating shaft structure for the control box. Utility Model Content

[0005] The purpose of this invention is to provide an operating box damping shaft structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a damping shaft structure for an operating box, comprising a shaft base, a fixed cylinder fixedly mounted on the upper surface of the shaft base, a plurality of positioning holes provided on the outer wall of the upper surface of the fixed cylinder, the plurality of positioning holes being circumferentially distributed at equal intervals through the center point of the fixed cylinder, a rotating seat rotatably mounted inside the fixed cylinder, the upper surface of the rotating seat being provided with a plurality of uniformly distributed primary holes and secondary holes, each of the primary holes being fitted with a ball screw.

[0007] Preferably, a plurality of the primary holes and secondary holes are circumferentially distributed at equal intervals around the center point of the rotating seat, and the diameter of the primary holes is larger than the diameter of the secondary holes.

[0008] Preferably, an inner limiting ring is fixedly installed on the inner wall of the fixed cylinder.

[0009] Preferably, a connecting column is fixedly connected to the lower surface of the rotating seat.

[0010] Preferably, a limiting plate that cooperates with the inner limiting ring is fixedly installed at the bottom end of the connecting column.

[0011] Preferably, the rotating seat, connecting column, and limiting plate are designed as an integral molded structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] After the rotating seat is assembled inside the fixed cylinder, the limiting plate can be placed below the inner limiting ring. In this way, the upper and lower limits of the rotating seat can be limited by the cooperation of the limiting plate and the inner limiting ring, so as to prevent the rotating seat from moving up and down inside the fixed cylinder. This effectively prevents the rotating seat from falling out of the fixed cylinder, and has a good limiting effect, effectively improving the operational stability of the rotating shaft structure of this utility model.

[0014] The operating box shaft structure of this utility model, when actually locked, has a ball screw installed in each primary hole. Therefore, when the rotating seat rotates inside the fixed cylinder, the ball is pushed by the spring with a certain pressure of the ball screw to move, so that it can lock and position the rotation between the fixed cylinder and the rotating seat. It has a good actual use effect of positioning and locking the internal rotation structure of the shaft, which can meet the different use needs of the operating box for the shaft and reduce the limitation of use.

[0015] During the locking and rotating process, the pressure spring of the ball screw can provide a certain damping effect to ensure normal use. Attached Figure Description

[0023] Please see Figure 1-3 The present invention provides an embodiment of a damping shaft structure for an operating box, comprising a shaft base 1, a fixed cylinder 2 fixedly mounted on the upper surface of the shaft base 1, a plurality of positioning holes 3 provided on the outer wall of the upper surface of the fixed cylinder 2, the plurality of positioning holes 3 being circumferentially distributed at equal intervals through the center point of the fixed cylinder 2, a rotating seat 5 being rotatably mounted inside the fixed cylinder 2, the upper surface of the rotating seat 5 being provided with a plurality of evenly distributed primary holes 8 and secondary holes 9, each primary hole 8 being fitted with a ball screw;

[0024] A ball screw is a fastener with a special structure, also known as a positioning screw or positioning bead screw. It consists of a spring, steel balls, and a housing.

[0025] The working principle of a ball screw is that a spring pushes a steel ball to move within the housing, thereby positioning and fixing the locking component. This design allows the ball screw to provide a stable positioning effect under pressure, making it particularly suitable for applications requiring high-precision positioning.

[0026] When used in this utility model, the ball is pushed by a spring with a certain pressure to move, so that it can lock and position the rotation between the fixed cylinder 2 and the rotating seat 5. It has a good actual use effect of positioning and locking the internal rotation structure of the rotating shaft, which can meet the different use requirements of the control box for the rotating shaft and reduce the limitations of use.

[0027] For further details, please refer to the appendix to the instruction manual. Figure 1 and Figure 3As shown, the primary hole 8 and the secondary hole 9 are distributed circumferentially at equal intervals around the center point of the rotating seat 5, and the diameter of the primary hole 8 is larger than the diameter of the secondary hole 9.

[0028] Based on the above structure, the operating box rotating shaft structure of this utility model, in actual use, since each primary hole 8 is equipped with a ball screw, when the rotating seat 5 rotates inside the fixed cylinder 2, the ball is pushed by a spring with a certain pressure of the ball screw to move, so that it can lock and position the rotation between the fixed cylinder 2 and the rotating seat 5. It has a good actual use effect of positioning and locking the rotating structure inside the shaft, which can meet the different use requirements of the operating box for the rotating shaft and reduce the limitations of use.

[0029] In this embodiment, in order to internally limit the rotation of the rotating seat 5 and prevent the rotating seat 5 from moving up and down and getting out of the fixed cylinder 2, an inner limiting ring 4 is fixedly installed on the inner wall of the fixed cylinder 2.

[0030] Among them, a connecting column 6 is fixedly connected to the lower surface of the rotating seat 5, and a limiting plate 7 that cooperates with the inner limiting ring 4 is fixedly installed at the bottom end of the connecting column 6.

[0031] After the rotating seat 5 is assembled inside the fixed cylinder 2, its limiting plate 7 can be placed below the inner limiting ring 4. In this way, the upper and lower limits of the rotating seat 5 can be limited by the cooperation of the limiting plate 7 and the inner limiting ring 4, so as to prevent the rotating seat 5 from moving up and down inside the fixed cylinder 2. This effectively prevents the rotating seat 5 from falling out of the fixed cylinder 2, and has a good limiting effect, effectively improving the operational stability of the rotating shaft structure of this utility model.

[0032] In this embodiment, in order to facilitate the integrated production of the internal rotating structure, the rotating seat 5, the connecting column 6, and the limiting plate 7 are designed as an integrated molding structure.

[0033] Working principle: When in use, this utility model can be installed inside the machine tool's control box by rotating the base 1, thereby ensuring the normal use of the rotating shaft structure of this utility model;

[0034] This utility model allows the rotating seat 5 to rotate inside the fixed cylinder 2, thereby ensuring the normal rotation effect of the rotating shaft;

[0035] When it is necessary to lock and position the rotating seat 5, a ball screw can be installed in the first-stage hole 8 of the rotating seat 5. The ball screw is a fastener with a special structure, also known as a positioning screw or positioning ball screw. It consists of a spring, a steel ball and a housing.

[0036] The working principle of a ball screw is that a spring pushes a steel ball to move within the housing, thereby positioning and fixing the locking component. This design allows the ball screw to provide a stable positioning effect under pressure, making it particularly suitable for applications requiring high-precision positioning.

[0037] The operating box shaft structure of this utility model, when actually locked, has a ball screw installed in each primary hole 8. Therefore, when the rotating seat 5 rotates inside the fixed cylinder 2, the ball is pushed by the spring under a certain pressure of the ball screw, so that it can lock and position the rotation between the fixed cylinder 2 and the rotating seat 5. It has a good actual use effect of positioning and locking the internal rotation structure of the shaft, which can meet the different use requirements of the operating box for the shaft and reduce the limitation of use.

[0038] During the tightening and rotation process, the pressure spring of the ball screw provides a certain degree of damping, ensuring normal operation.

[0039] After the rotating seat 5 is assembled inside the fixed cylinder 2, its limiting plate 7 can be placed below the inner limiting ring 4. In this way, the upper and lower limits of the rotating seat 5 can be limited by the cooperation of the limiting plate 7 and the inner limiting ring 4, so as to prevent the rotating seat 5 from moving up and down inside the fixed cylinder 2. This effectively prevents the rotating seat 5 from falling out of the fixed cylinder 2, and has a good limiting effect, effectively improving the operational stability of the rotating shaft structure of this utility model.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
