Description

Disposable high-speed turbine head

technical field

This invention relates to disposable high speed turbine handpieces.

Background technique

At present, the pneumatic turbine heads on the market all adopt the nose shell, and the upper end cover of the nose shell is provided with a loam cake structure. In the production process of the machine head shell, it is necessary to set up air intake channels, water vapor channels, and exhaust channels. The production process is complex and troublesome, and it cannot be supported by simple die-casting or injection molding. In addition, during the working process of the machine head, due to the small weight of the running block and the uniform thickness of the wall surface of the machine head, it is easy to generate vibration.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the existing turbine head, the present invention provides a disposable high-speed turbine head.

The technical solution of the present invention to solve its technical problems is: a disposable high-speed turbine head, including a head casing with a connecting handle at the rear end, an air inlet passage and an exhaust passage are arranged on the connecting handle, and the head casing is composed of The left shell and the right shell are composed of the left shell and the right shell, and the middle part of the left shell and the right shell is connected to form an air turbine chamber.

Further, the front ends of the left shell and the right shell are provided with convex parts, and the convex parts of the front ends of the left shell and the right shell are respectively provided with fixing holes and fixing columns. The column is fixed. The convex part is set to increase the counterweight, which improves the stability of the machine head.

Preferably, the rear ends of the left shell and the right shell are respectively provided with a second fixing hole and a second fixing column.

Preferably, the handle of the left housing is provided with a left water vapor tank, the handle of the right housing is provided with a right water vapor tank, and the left water vapor tank and the right water vapor tank form a water vapor channel.

Preferably, the first fixing hole is a riveting hole, and the first fixing post is a riveting post.

Preferably, the upper air intake slot is provided with an inclined section close to the chamber of the air turbine, and the inclined section is approximately tangential to the side wall of the chamber of the air turbine.

Preferably, the contact surface between the left shell and the right shell is a refined grinding surface. The fine grinding surface contact is used to ensure the firm contact between the upper shell and the lower shell. Further, a rubber sealing ring can also be used for sealing, and the rubber sealing ring is arranged between the contact surface of the upper shell and the lower shell.

To further play a sealing role, the outside surface of the left shell and the right shell is wrapped with a sealing layer after fastening.

When in use, the head counterweight reduces the vibration of the side wall of the machine head and improves the stability of the product. When in use, you only need to put the pneumatic components in, and the left shell and the right shell are buckled and sealed to use.

The invention has the beneficial effects of simple structure, convenient production, greatly reduced production cost, improved product production rate, greatly reduced product vibration, and improved operational stability.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 and 2: a disposable high-speed turbine head, including a head shell 2 with a connecting handle 1 at the rear end, the connecting handle 1 is provided with an air inlet channel and an exhaust channel, and the head shell 2 It consists of a left shell 2-1 and a right shell 2-2, the left shell 2-1 and the right shell 2-2 are connected in the middle to form an air turbine cavity.

In this embodiment, the front ends of the left shell 2-1 and the right shell 2-2 are provided with protrusions 2-3, and the front ends of the left shell 2-1 and the right shell 2-2 are respectively provided with fixing holes. 2-4. The fixing column 2-5, the front ends of the left shell 2-1 and the right shell 2-2 are fixed to the fixing column 2-5 through the fixing hole 2-4. The convex part is set to increase the counterweight, which improves the stability of the machine head.

In this embodiment, the rear ends of the left shell 2-1 and the right shell 2-2 are respectively provided with a second fixing hole 2-6 and a second fixing post 2-7.

In this embodiment, the handle of the left shell 2-1 is provided with a left water vapor tank, the handle of the right shell 2-2 is provided with a right water vapor tank, and the left water vapor tank and the right water vapor tank form a water vapor channel.

In this embodiment, the first fixing hole is a riveting hole, and the first fixing post is a riveting post.

In this embodiment, the upper air inlet slot is provided with an inclined section close to the air turbine chamber, and the inclined section is approximately tangential to the side wall of the air turbine chamber.

In this embodiment, as a sealing method: the contact surface between the left shell and the right shell is a finely ground surface. The fine grinding surface contact is used to ensure the firm contact between the upper shell and the lower shell. A rubber sealing ring can also be used for sealing, and the rubber sealing ring is arranged between the contact surface of the upper shell and the lower shell. This embodiment lists two sealing methods, but is not limited to these two, and conventional sealing methods in the prior art can also be used.

In this embodiment, it further functions as a seal, and the outer surface of the left shell 2-1 and the right shell 2-2 is clasped with a sealing layer after fastening.
