Description

Technical Field

[0001] This invention belongs to the field of handwheel technology, specifically relating to a handwheel and a processing mold. Background Technology

[0002] The handwheel drives the mating screw to move along the axis by rotating. To make the screw move more smoothly, a lubricant needs to be added to the screw surface to reduce friction and improve smoothness.

[0003] The existing method of adding lubricant is mainly manual. Manual addition has the problem of lubricant falling off, which leads to pollution of the production environment, waste of lubricant, and is also a high-frequency waste of human resources.

[0004] In summary, a handwheel with a lubrication structure is provided to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a handwheel and a processing mold.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides a handwheel having a boss; The boss is provided with a lubrication cavity; The boss is detachably connected to a cover plate for covering the outlet side of the lubrication cavity; The cover plate is provided with a through hole for the screw to pass through.

[0007] In this invention, the lubrication cavity in the boss is used to store grease or lubricating oil. When used to store lubricating oil, it is necessary to use a carrier that can absorb lubricating oil for assistance, such as asbestos rope. This invention stores grease or lubricating oil through the lubrication cavity, thereby avoiding dripping and environmental pollution caused by manual application. The cover plate completely seals off the lubrication chamber to prevent a large amount of lubricating oil or grease from leaking out. The through holes on the cover plate are for the screw to pass through. When the screw passes through the lubrication chamber, it will adhere to the lubricating oil or grease therein, thus playing a lubricating role. Or in some cases, the lubricating oil or grease will leak from the gap between the screw and the through hole, and self-lubricate the screw along the thread. When the lubricating oil or grease is used up, you only need to remove the cover plate and add it again. This invention enables automatic lubrication of the screw when using the handwheel, which can effectively reduce the workload, improve the timeliness of lubrication, and ensure the smooth operation of the screw. This invention integrates the lubrication chamber into the handwheel, resulting in a simple and reliable overall structure. Lubricating oil or grease can be added after removing the cover plate, making operation convenient.

[0008] Secondly, the present invention provides a processing mold for producing the aforementioned handwheel.

[0009] The beneficial effects of this invention are: 1. The lubrication chamber stores grease or oil, thus avoiding dripping and environmental pollution caused by manual application; 2. The lubrication chamber is integrated into the handwheel, resulting in a simple, reliable overall structure that also facilitates the production and processing of the handwheel; 3. When the screw passes through the lubrication cavity, it will adhere to the lubricating oil or grease therein, thus playing a lubricating role. In some cases, the lubricating oil or grease may leak from the gap between the screw and the through hole, and self-lubricate the screw along the thread. This can greatly improve the automation of lubrication, reduce manual intervention, and free up workers. Attached Figure Description

[0011] The technical solutions of the present invention will be described in detail below with reference to specific embodiments and accompanying drawings. The embodiments described herein are specific implementations of the present invention, used to illustrate the concept of the present invention; these descriptions are explanatory and exemplary, and should not be construed as limiting the implementation methods or the scope of protection of the present invention. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein. Example 1

[0012] like Figure 1 , 2 As shown, this embodiment provides a handwheel with a boss 1 and a mounting hole for mounting a screw. The lubrication cavity 2 is coaxially distributed with the mounting hole and is interconnected with it. The boss 1 is provided with a lubrication cavity 2; The boss 1 is detachably connected to the cover plate 3 used to cover the outlet side of the lubrication chamber 2; The cover plate 3 is provided with a through hole 32 for the screw to pass through.

[0013] In this embodiment, the handwheel is adapted to the situation in actual production where it rotates along with the screw and moves about the axial direction. This situation is common when the screw is arranged vertically. The screw is installed through the mounting hole of the handwheel and passes through the lubrication chamber 2, which stores lubricating oil. The lubricating oil is attached by the asbestos rope. Under the influence of gravity, the lubricating oil flows down through the gap between the screw and the through hole 32, and self-lubricates the entire screw along the threads on the screw surface. Example 2

[0014] like Figure 3 , 4 As shown, this embodiment provides a handwheel with a boss 1 and a mating hole for driving a screw. The lubrication cavity 2 is coaxially distributed with the mating hole and is connected to it. The boss 1 is provided with a lubrication cavity 2; The boss 1 is detachably connected to the cover plate 3 used to cover the outlet side of the lubrication chamber 2; The cover plate 3 is provided with a through hole 32 for the screw to pass through.

[0015] In this embodiment, the handwheel is adapted to the actual production situation where the handwheel only rotates and does not move axially with the screw. This situation is common when the screw is arranged vertically or horizontally. In this case, the screw will move relative to the handwheel. The lubrication chamber 2 can store both lubricating oil and lubricating grease. When the screw passes through the lubrication chamber 2, the screw comes into contact with the lubricating oil or lubricating grease inside, thereby adhering the lubricating oil or lubricating grease to the threads on its own surface, thus playing a lubricating role. Example 3

[0016] like Figure 2 , 4 As shown in Figures 5 and 6, this embodiment provides a handwheel. The difference from embodiment 1 or 2 is that a sealing element is connected between the cover plate 3 and the lubrication cavity 2. The side of the cover plate 3 facing the boss 1 is provided with a limiting ring 31 that matches the inner diameter of the lubrication cavity 2. The outer wall of the limiting ring 31 is provided with an installation groove 35 for installing the sealing element.

[0017] In this embodiment, when the cover plate 3 is installed, the limiting ring 31 is inserted into the matching lubrication cavity 2, thereby determining the relative positional relationship between the cover plate 3 and the boss 1. The seal is used to seal the joint between the cover plate 3 and the lubrication chamber 2 to prevent lubricating oil or grease from leaking from the joint and causing contamination.

[0018] In some optional instances, the seal is a sealing ring, such as a lip seal. Example 4

[0019] like Figure 2 , 4 As shown in Figures 5 and 6, this embodiment provides a handwheel, which differs from Embodiments 1 or 2 in that the cover plate 3 and the boss 1 are magnetically connected. The side of the cover plate 3 that contacts the boss 1 is provided with a mounting groove 34, in which a magnet 4 with adsorption capacity is installed.

[0020] In this embodiment, in order to facilitate the disassembly and assembly of the cover plate 3 when adding lubricating oil or grease, a magnetic connection is adopted, in which the magnet 4 in the mounting groove 34 is attracted to the boss 1, thereby installing the cover plate 3 on the boss 1.

[0021] In some alternative examples, a groove 33 is provided on the circumference of the cover plate 3 to facilitate the application of force when moving the cover plate 3. Example 5

[0022] This embodiment provides a handwheel, which differs from embodiments 1 or 2 in that the cover plate 3 and the boss 1 are bolted together.

[0023] In this embodiment, in order to ensure the complete reliability of the connection and to prevent the cover plate 3 from accidentally falling off, the cover plate 3 is installed by bolt connection.

[0024] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
