Description

Technical Field

[0001] The present application belongs to the field of dry mill shock absorbing structures, and in particular relates to a dry mill shock absorbing mechanism. Background Art

[0002] The dry grinder relies on an eccentric structure to achieve vibration and then grind the surface. The grinding process usually takes a long time, and the vibration of the machine body is transmitted to the arm, causing the arm to easily fatigue. The current shock absorption methods mainly focus on providing shock-absorbing rubber on the hand grip, or providing shock-absorbing rubber between the hand grip and the machine body. The shock-absorbing rubber is very easy to degenerate in a high temperature environment, thereby affecting the shock-absorbing function. The present technical solution mainly solves this problem. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a dry grinder damping mechanism that can solve the problems in the related art.

[0004] The present application provides a dry mill vibration reduction mechanism, comprising:

[0005] The shock-absorbing member is located between the vibration component and the shell, providing a preload force to play a buffering role. The shock-absorbing member is provided with a base, a notch and a protrusion; the notch and the protrusion correspond to each other, and the notch and the protrusion are located on the base. The base is a rotating body structure, and the base is hollow, and the vibration component motor is accommodated in the hollow part; the protrusion is an arc structure, and the protrusion part is bent away from the port at one end connected to the base, so that the protrusion is easy to contact with the shell.

[0006] Furthermore, the number of the notches and protrusions is several and they correspond one to one, which is convenient for sheet metal stamping manufacturing. The notches and protrusions are evenly distributed on the base body, which can make the vibration component evenly stressed in the circumferential direction. At the same time, it also prolongs the service life of the shock absorbing component.

[0007] Furthermore, it also includes a rubber piece arranged on the protrusion; the rubber piece matches the protrusion, and the rubber piece is sleeved on the protrusion to prevent the protrusion from scratching the inner wall of the shell.

[0008] The technical solution is mainly to preset notches and protrusions on the shock absorbing member, and the protrusions can be arc-shaped. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Example

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0016] In the following, in conjunction with the accompanying drawings, a dry grinder damping mechanism provided by the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0017] refer to Figure 1-3 , a dry mill shock absorbing mechanism provided in an embodiment of the present application may include:

[0018] The shock absorbing member 3 is located between the vibration component 4 and the housing 1. The vibration component 4 mainly refers to the motor, and F refers to the rotation direction of the dry grinder motor. It should also include other vibration structures, such as a transmission structure or a bearing structure.

[0019] Combination Figure 1 The switch assembly 2 of the dry grinder is located on the housing 1, and the housing 1 also contains a vibration component 4 and an eccentric assembly 5 in order. The above components are essential components of the dry grinder. The shock absorbing component 3 of the technical solution is located between the vibration component 4 and the housing 1, and the shock absorbing component 3 is sleeved around the vibration component 4, so that the shock absorbing component 3 and the vibration component 4 are in good contact and the force is evenly applied. When the eccentric assembly 5 rotates, it will drive the vibration component 4 and the housing 1 to vibrate.

[0020] The shock-absorbing member 3 is provided with a base 31, a notch 32 and a protrusion 33; the base 31 is a stamped sheet metal part, which is enclosed into a rotating body structure after stamping. The notch 32 and the protrusion 33 are located on the base 31, and there are a plurality of notches 32 and protrusions 33, which correspond to each other one by one and are formed by stamping. The protrusion 33 is an arc-shaped structure, and the protrusion 33 is bent away from the port connected to the base 31, and its arc curvature is preferably matched with the inner cavity of the shell 1 accommodating the structure, so that the shock-absorbing member 3 and the shell are in good contact, the force is evenly applied, and the service life of the shock-absorbing member 3 is extended.

[0021] The base 31 is a rotating body structure, and the base 31 is hollow, and the motor is accommodated in the hollow part. The base 31 can be a discontinuous structure. When the base 31 contacts the vibration component 4 at several points, the point contact referred to here should be uniform circumferential point contact, so that the body 31 is evenly stressed. The base 31 contacts the shell 1 at one point, and the point contact referred to here should also be uniform circumferential point contact. The above two types of point contacts, the several point contacts between the base 31 and the vibration component 4 and the point contact between the base 31 and the shell 1, should not be on the same plane to avoid the shock absorber 3 only acting as an intermediate component without a shock absorbing effect.

[0022] A rubber piece matching the protrusion 33 is also provided on the protrusion 33. The rubber piece can be made of drip glue, or made in advance and put on the protrusion 33. Silicone is preferred. The main purpose is to prevent the protrusion 33 from scratching the inner wall of the shell 1, and it can also buffer part of the vibration. Since the shock absorbing member 3 is located between the vibration component 4 and the shell 1, and the protrusion 33 provides a pre-tightening force, the pre-tightening force can well buffer part of the vibration, and the sheet metal is not easy to deteriorate after the dry grinder has worked for a period of time and the temperature rises, and the stability is high. Therefore, the shock absorbing structure has a good effect and a long service life.

[0023] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
