Description

A pipe internal and external grinding machine

technical field

The invention belongs to the technical field of material forming automation, and in particular relates to a device for quickly grinding the inside and outside of the pipe end during the manufacturing process of the closed pipe.

Background technique

In industries such as shipbuilding and chemical industry, a large number of pipelines need to be laid. When two pipelines need to be connected, flanges need to be welded at both ends of the pipes, and then the two flanges are connected with bolts. When the pipe needs to be welded with the flange, the inside and outside of the end of the pipe need to be ground to ensure the welding quality. Due to the large number of required pipes of different sizes, it is faced with the problem of grinding both ends of a large number of pipes.

Most production enterprises mainly use manual grinding, that is: workers hold electric or pneumatic grinding machines to first grind the outer wall of the pipe and then polish the inner wall. It has the following main problems, that is, the efficiency of manual grinding is low, and the inside and outside grinding cannot be done at the same time; for some large pipe fittings, auxiliary rotating equipment is needed to help the grinding; the labor intensity of workers is high, and the working environment is harsh.

Contents of the invention

The purpose of the present invention is to provide a pipe internal and external grinding machine, which can effectively grind the internal and external walls of the pipe simultaneously, so as to solve the problem of low efficiency existing in the prior art.

To achieve the above object, the present invention adopts the following technical solutions:

A pipe internal and external grinding machine, including a fixed guide rail, a mobile platform, a lifting platform, a grinding system, transmission rollers, a fixed frame and a roller support transmission frame,

Among them, the fixed guide rail is installed on the horizontal plane;

The mobile platform is installed on the fixed guide rail and can move horizontally along the fixed guide rail;

The lifting platform is installed on the mobile platform and can be lifted up and down along the mobile platform;

The grinding system is installed on the lifting table, including the outer grinding wheel grinding system and the inner grinding wheel grinding system. The outer grinding wheel grinding system is used for grinding the outer wall of the pipe, and the inner grinding wheel grinding system is used for grinding the inner wall of the pipe;

The roller support drive frame is installed on the fixed guide rail and can move horizontally along the fixed guide rail;

The transmission roller is installed on the roller support transmission frame;

The fixed frame is installed on the roller support transmission frame.

The mobile platform is a platform on which wheels are installed below and can slide back and forth along a fixed guide rail on a horizontal plane; a control system is installed above it.

The lifting platform is slidingly connected with the mobile platform through the parallel guide rails installed on the vertical horizontal plane.

Both the outer grinding wheel grinding system and the inner grinding wheel grinding system are composed of a set of driving motor, transmission wheel, transmission belt and grinding wheel. The motor drives the grinding wheel to rotate through the transmission wheel.

The fixed frame is a Z-shaped steel, one end of the Z-shaped steel is provided with a cylinder top wheel, and the other end is connected with the roller support transmission frame through two cylinders.

The roller support drive frame is a support platform with wheels installed on the fixed guide rail at the bottom, and driven by a motor.

Two wheels are respectively arranged on both sides of the said roller supporting transmission frame, and the distance between the two wheels is adjusted manually.

The fixed guide rail is two parallel guide rails fixedly installed on the ground.

As a further improvement, the above-mentioned grinding machines are two symmetrically arranged. Both ends of the pipe can be sanded at the same time.

The two grinding machines are arranged oppositely on the same fixed guide rail.

Place the pipe on the roller support drive frame, and fix the pipe against movement through the two cylinders of the Z-shaped fixed frame; by adjusting the height of the lifting platform, the two grinding wheels of the grinding system are at the same height as the inner wall and outer wall of the pipe The two mobile platforms of the pipe grinding machine will automatically move to the corresponding positions at both ends of the pipe; the inner and outer walls of the pipe are pneumatically clamped;

The beneficial effects of the present invention are: the present invention is simple in structure, safe in use in terms of adjustment, replaces traditional manual operation with automatic grinding, has high efficiency, and is especially suitable for batch grinding. Compared with manual grinding, it has high efficiency, can grind inside and outside at the same time, and the labor intensity of workers is low. Moreover, the inner and outer walls of both ends of the pipe can be polished at the same time, which greatly improves the grinding efficiency.
