Description

Technical Field

[0001] This utility model relates to a tire clamping device for a tire changer, and more particularly to a connector for the tire clamping device for a tire changer. Background Technology

[0002] When repairing vehicle tires, tire changers are generally used to remove and install tires. Tire changers use tire clamping devices to clamp the tires before removing and installing them. The tire clamping devices usually have multiple jaws on a support plate, and the jaws are controlled by a pneumatic cylinder to clamp the tires. This type of tire clamping device has a simple structure and is easy to operate.

[0003] Tire clamping devices typically require multiple pneumatic cylinders to control the movement of the grippers and multiple drive medium lines connecting the cylinders. These drive lines are all exposed externally, resulting in a relatively large number of lines that are messy and take up a lot of space, making the clamping components larger and affecting their compactness. Operating the tire changer can also easily damage the pneumatic lines, affecting tire removal efficiency and increasing maintenance costs. The large space occupied by the drive lines also increases the size and compactness of the tire clamping device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a connector for connecting the clamping disc and the drive cylinder for a tire clamping device that can reduce the number of drive lines and arrange them in an orderly manner.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a connector for a tire clamping device of a tire changer, the connector comprising a hexahedral structure consisting of three evenly distributed drive component mounting surfaces and three truncated surfaces arranged alternately with the drive component mounting surfaces, the connector having an internal channel, the drive component mounting surfaces communicating with each other through the internal channel, and the truncated surfaces being drive medium input / output connection parts.

[0006] Furthermore, the radial cross-section of the hexahedral structure is a truncated equilateral triangle.

[0007] A preferred embodiment of this invention is a connector in which the internal channel includes a first driving medium inlet / outlet hole on a truncated face, and three first internal channels are provided inside the connector. The first internal channels are connected to one of the first driving medium inlet / outlet holes, and each driving component mounting surface is connected to two of the first internal channels.

[0008] A preferred embodiment of the present invention is a connector in which the internal channel further includes a second driving medium inlet / outlet hole and a third driving medium inlet / outlet hole provided on the truncated surface, and a second internal channel connecting the second driving medium inlet / outlet hole and the third driving medium inlet / outlet hole is provided inside the connector.

[0009] A preferred embodiment of this invention is a connector in which the upper part of the connector has a necked structure.

[0010] A preferred embodiment of this invention is a connector in which a shaft hole is provided at the center.

[0011] A preferred embodiment of this invention is a connector in which a mounting protrusion is provided on the surface of the mounting surface of the drive component, and a through groove is provided inside the mounting protrusion.

[0012] A preferred embodiment of this invention is a connector in which a sealing groove is provided on the outside of the mounting convex ring.

[0013] Compared with the prior art, the connector of this utility model has the following advantages: the three faces of the connector's triangular structure serve as the mounting surfaces for the drive component. Mounting the drive component on these surfaces minimizes the distance from the outer end face to the rotation center, thereby reducing the volume of the clamping component. The connector's internal channel design allows most of the external drive gas pipelines to be replaced by internal channels, optimizing the spatial layout and making the clamping device compact and smaller in size, thus avoiding mechanical damage caused by messy pipelines.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-3 As shown, in this embodiment, the connector 4 used to connect the clamping disc and the driving cylinder has a hexahedral structure, consisting of three evenly distributed driving component mounting surfaces 42 and three truncated surfaces 43 arranged alternately with the driving component mounting surfaces 42. Its radial cross-section is approximately the shape formed by removing three corners from an equilateral triangle; the face with the three corners removed is the truncated surface 43. The upper part of the connector 4 is a necked structure 49, and the upper surface of the necked structure 49 is fixedly connected to the clamping disc 1. The driving component mounting surfaces 42 and the truncated surfaces 43 are spaced apart to form a hexahedral structure on the side surfaces. The connector 4 has a shaft hole 41 at its center. Each drive component mounting surface 42 has a mounting protrusion 420 for mounting the drive component. The mounting protrusion 420 has a sealing groove 421 on its outside. The cylinder end 31 of the piston drive component 3 is fitted onto the mounting protrusion 420 of the drive component mounting surface 42 and sealed by the rubber sealing ring provided in the sealing groove 421. The piston drive component 3 is fixed to the connector 4 with bolts.

[0021] In this embodiment, an inner channel connector is provided on the truncated surface 43 to form an inlet and outlet for introducing or exporting driving gas to the connector 4. The driving component mounting surfaces 42 are interconnected through the internal channels. Each driving component mounting surface 42 is connected to two first inner channels 45. A first driving medium inlet / outlet hole 44 is provided on one of the truncated surfaces 43 of the connector 4. An air inlet pipeline can be connected to the first driving medium inlet / outlet hole 44. A first inner channel 45 is provided inside the connector 4. One of the first inner channels 45 is connected to the first driving medium inlet / outlet hole 44. The driving component mounting surface 42 has mounting screw holes 422 on its surface, and the driving component (not shown in the figure) is fixedly installed by bolts. After the driving component is connected and fixedly installed, the three driving component mounting surfaces 42 are connected to the first inner channels 45 in pairs through through grooves 423, so that the three first inner channels 45 are interconnected. After connection, the driving gas entering the three first inner channels 45 can drive the piston to move. A second driving medium inlet / outlet hole 46 and a third driving medium inlet / outlet hole 47 are provided on one of the truncated surfaces 43 of the connector 4. A second inner channel 48 is provided inside the connector 4 to connect the second driving medium inlet / outlet hole 46 and the third driving medium inlet / outlet hole 47. The second driving medium inlet / outlet hole 46 introduces an external gas source and enters the third driving medium inlet / outlet hole 47 through the second inner channel 48. The third driving medium inlet / outlet hole 47 can be connected to the driving component.
