Description

Technical Field

[0001] This utility model relates to a tire changer, and more particularly to a single gripper component for a tire clamping device of a tire changer. Background Technology

[0002] During vehicle tire maintenance and repair, a tire changer is needed to remove or install tires from the rim. The tire changer typically uses a type of tire clamping device with claws to hold the tire during the removal and installation process. The structure of the claws has a significant impact on the effectiveness of holding the tire.

[0003] Existing gripper components are mostly modular structures. On the one hand, the gripper head and the hull are generally composed of multiple parts, requiring assembly due to the large number of components. On the other hand, the gripping force of the gripper teeth is poor, which affects the gripping of the tire. In addition, the contact surface between the gripper component and the tire is generally flat, which also affects the gripping of the rim and the fit between the tire, rim and gripper component is not tight enough. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a single gripper component for a tire changer clamping device with fewer parts and better clamping effect.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a single gripper component for a tire changer, including a hull, a gripper body is provided on the upper part of the hull, and a spacer block is provided at the bottom of the hull. The gripper component is a single multi-arc surface gripper integrally formed.

[0006] In a preferred embodiment of the gripper component of this utility model, the gripper body includes an inner clamping part and an outer supporting surface facing opposite to the inner clamping part. The inner clamping part includes an inner toothed surface with locking teeth and an inclined transition surface. The outer supporting surface includes an outer toothed surface with locking teeth and an upper inclined surface.

[0007] In a preferred embodiment of the gripper component of this utility model, the inner tooth surface is a concave arc surface.

[0008] In a preferred embodiment of the gripper component of this utility model, the surface of the inclined transition surface is an inwardly concave spherical crown-shaped surface.

[0009] In a preferred embodiment of the gripper component of this utility model, the outer tooth surface is an outwardly raised arc surface.

[0010] Furthermore, at least one spacer plane is provided in the middle of the internal tooth surface, and at least one spacer plane is provided in the middle of the external tooth surface.

[0011] In a preferred embodiment of the gripper component of this utility model, the hull includes an outer inclined surface and an inner inclined surface, both of which are curved surfaces that bulge towards the center in the vertical direction.

[0012] In a preferred embodiment of the gripper component of this utility model, the bottom of the spacer block is provided with a first fixing hole and a second fixing hole.

[0013] Compared with the prior art, the gripper component of this utility model has the following advantages: the one-piece molding makes the gripper component only a single part, and fewer parts can reduce manufacturing costs and maintenance costs; the use of arc-shaped toothed surfaces can better fit the wheel rim and improve the clamping effect; the use of inwardly concave spherical transition surfaces can make the contact angle between the edge of the wheel rim and the gripper body smaller; the use of curved surfaces on the inclined surface of the hull can reduce the frictional resistance between the tire and the gripper body during clamping.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Please see Figure 1-3As shown, in this embodiment, the gripper component 2 is a single-piece multi-arc gripper, which is integrally formed. This single-piece forming means the gripper component is only one part, reducing manufacturing costs and maintenance expenses. The gripper component 2 includes a hull 25, with a gripper body 20 disposed on the upper part of the hull 25. A spacer block 253 is provided at the bottom of the hull 25. The bottom of the spacer block 253 has a first fixing hole 254 and a second fixing hole 255.

[0019] In this embodiment, the gripper body 20 includes an inner gripping portion and an outer support surface facing opposite to the inner gripping portion. The inner gripping portion of the gripper body 20 is used to grip the outer edge of the rim. The inner gripping portion includes an inner tooth surface 23 with locking teeth and an inclined transition surface 231. The inner tooth surface 23 of the inner gripping portion grips the edge of the rim through the locking teeth of the gripper. The inner tooth surface 23 is a concave arc surface. The surface of the inclined transition surface 231 is a concave spherical crown-shaped surface. The outer support surface includes an outer tooth surface 21 with locking teeth and an upper inclined surface 211. The locking teeth of the outer tooth surface 21 are used to contact and support the edge of the rim. The outer tooth surface 21 is an outwardly convex arc surface. At least one spacer plane 200 is provided in the middle of the inner tooth surface 23 and the middle of the outer tooth surface 21, respectively. The tooth surface divided by the spacer plane has a better gripping effect. The hull 25 includes an outer inclined surface 251 and an inner inclined surface 252. Both the outer inclined surface 251 and the inner inclined surface 252 are curved surfaces that bulge towards the middle in the vertical direction. The middle part of the hull 25 is a hollow structure 256.

[0020] Using a rounded tooth surface can better fit the rim and improve the clamping effect. Using an inwardly concave spherical transition surface can make the contact angle between the tire rim edge and the clamping body smaller. Using a curved surface on the hull's inclined surface can reduce the frictional resistance between the tire and the clamping body during clamping.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
