Description

Technical Field

[0001] The utility model relates to the technical field of rotating tooling lock shafts, and particularly relates to a lock shaft tooling mechanism. Background Art

[0002] The lock shaft mechanism plays a key role in mechanical equipment and is widely used in the movement of rotating tooling. Its purpose is to ensure the stability and precision of mechanical components by locking the position of the shaft. Traditional lock shaft mechanisms usually use mechanical methods such as top bead screws, oil seals, and O-rings to lock the shaft. These methods achieve the locking of the shaft through mechanical extrusion or sealing.

[0003] Firstly, the top bead screw lock shaft method relies on the pressure of the screw to press the bead against the shaft. However, in actual operation, it is difficult to control the force. Excessive pressure may cause damage to the surface of the shaft, and conversely, insufficient pressure cannot effectively lock the shaft, affecting the normal operation of the equipment.

[0004] Secondly, although seals such as oil seals and O-rings can provide the lock shaft function to a certain extent, since they mainly rely on the friction with the shaft to achieve locking, long-term friction easily causes wear of the seals, thereby affecting their lock shaft performance. This wear not only shortens the service life of the seals but also reduces the lock shaft effect of the shaft under high-speed rotation, resulting in a decrease in the accuracy of the equipment.

[0005] Therefore, these defects of the prior art seriously affect the reliability and durability of the lock shaft mechanism and cannot meet the increasingly strict industrial requirements. To solve the above problems, a lock shaft tooling mechanism is proposed. Summary of the Utility Model

[0006] The main purpose of the utility model is to provide a lock shaft tooling mechanism, aiming to solve the problems that the existing lock shaft methods have uncontrollable force and are prone to cause wear of the seals.

[0007] To achieve the above utility model purpose, the utility model proposes a lock shaft tooling mechanism, which includes a base, and also includes a tooling shaft. The tooling shaft is arranged in the axial direction of the base central axis, the tooling shaft protrudes from the upper surface of the base, and a magnetic member is arranged on the base, and the magnetic member abuts against the tooling shaft.

[0008] Further, an installation seat is also arranged on the base for installing the magnetic member.

[0009] Further, the installation seat is provided with a magnetic attraction surface, and the magnetic attraction surface fits on the surface of the tooling shaft.

[0010] Further, the magnetic attraction surface is arc-shaped.

[0011] Further, the installation seat is provided with a through hole.

[0012] Further, a chamfer is provided on one side of the mounting base close to the tooling shaft.

[0013] Beneficial effects:

[0014] A locking shaft tooling mechanism of the present utility model includes a tooling shaft. The tooling shaft is arranged in the central axis direction of the base and protrudes from the upper surface of the base. A magnetic member is provided on the base and abuts against the tooling shaft. The magnetic member provided on the base contacts the tooling shaft through magnetic force to achieve locking. Since the magnetic member adsorbs the tooling shaft through magnetic force instead of relying on mechanical contact to achieve shaft locking, the problems of friction and wear in the traditional mechanical locking method are avoided. This design extends the service life of the tooling mechanism and reduces the frequency of maintenance and replacement. Description of the drawings

[0030] Referring to Figure 1 and Figure 2 As shown in [reference], an embodiment of a lock shaft tooling mechanism of a utility model includes a base 1, and further includes a tooling shaft 2. The tooling shaft 2 is arranged along the central axis direction of the base 1, the tooling shaft 2 protrudes from the upper surface of the base 1, and a magnetic member 3 is arranged on the base 1, and the magnetic member 3 abuts against the tooling shaft 2.

[0031] An installation base 4 is further provided on the base 1 for installing the magnetic member 3;

[0032] The installation base 4 is provided with a magnetic attraction surface 6, and the magnetic attraction surface 6 is attached to the surface of the tooling shaft 2;

[0033] The magnetic attraction surface 6 is arc-shaped;

[0034] The installation base 4 is provided with a through hole 5;

[0035] A chamfer 7 is provided on one side of the installation base 4 close to the tooling shaft 2.

[0036] In the embodiment of the present application, the base 1 is cylindrical. A positioning groove is provided in the axial center direction of the base 1, and the tooling shaft 2 is installed in the positioning groove. An installation base 4 is provided on the upper surface of the base 1, and a magnetic member 3 is installed on the installation base 4. The installation base 4 is fixed on the base 1 to play a role in stably supporting the magnetic member 3. After the tooling shaft 2 is installed in the positioning groove of the base 1, the magnetic member 3 is fixed on the installation base 4 and contacts the surface of the tooling shaft 2 through magnetic force. This magnetic force can stably lock the tooling shaft 2 in place without using traditional mechanical contact or pressure to achieve locking. The design of the installation base 4 ensures the stable installation of the magnetic member 3 and also ensures that the magnetic member 3 generates sufficient magnetic force to lock the tooling shaft 2, thereby realizing the non-contact shaft locking function. In the embodiment of the present application, the magnetic member 3 is a magnet.

[0037] An arc-shaped magnetic attraction surface 6 is provided on one side of the installation base 4 close to the tooling shaft 2. Through this arc-shaped design, the magnetic attraction surface 6 can better fit the surface of the tooling shaft 2. The arc-shaped design enables the magnetic member 3 to be in close contact with the surface of the tooling shaft 2 over a larger contact area, thereby enhancing the effect of the magnetic force. This design ensures that the magnetic force can be evenly distributed on the contact surface of the tooling shaft 2, making the tooling shaft 2 more stable in the locked state and less likely to move or loosen in position; at the same time, since the arc-shaped magnetic attraction surface 6 provides a more uniform force distribution, compared with the plane contact method, the stress concentration problem in the contact area is reduced. This not only reduces wear but also avoids potential damage caused by excessive local stress, thereby extending the service life of the equipment.

[0038] A through hole 5 is provided on the installation base 4. The design of the through hole 5 can provide a certain operating space for the installation of the magnetic member 3, making the installation and adjustment more convenient. Through the through hole 5, it is easier to insert tools or equipment to help fix or adjust the position of the magnetic member 3 to ensure good fit with the surface of the tooling shaft 2; at the same time, the magnetic material may generate a certain amount of heat during operation. The presence of the through hole 5 can promote air circulation and help dissipate heat, thereby maintaining the stable performance of the magnetic member 3 and avoiding magnetic weakening caused by overheating.

[0039] On both sides of the length direction of the mounting base 4 close to the tooling shaft 2, chamfers 7 are provided. The purpose of the chamfer 7 design is to reduce the sharpness of the edge, avoid stress concentration, and at the same time facilitate the assembly and adjustment of components.

[0040] In the lock shaft tooling mechanism of the embodiment of the present application, the tooling shaft 2 is attracted by a magnet to achieve the purpose of locking the shaft. The suction force of the magnet is determined by its inherent magnetic material and the distance from the tooling shaft 2. During the process of locking the shaft, the magnetic force will automatically adjust according to the proximity of the tooling shaft 2, and there is no need to manually adjust the force like the mechanical locking method. Therefore, the situation of excessive or insufficient force caused by improper operation is avoided; traditional mechanical lock shaft methods (such as top bead screws, O-rings, etc.) rely on physical contact to apply pressure, and surface wear of parts is likely to occur after long-term use. On the contrary, magnetic lock shaft is a non-contact method, and the tooling shaft 2 is locked by the acting force of the magnetic field. Therefore, it will not cause wear to the tooling shaft 2 or the magnet itself. This frictionless locking method extends the service life of the equipment and reduces the maintenance requirements.

[0041] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
