Description

Tumble polisher

[Technical Field] The mechanical processing equipment of the present utility model is specifically a drum polishing machine.

[Background Art] There are generally phenomena such as burrs, sharp edges, and oxide scales in machined parts, which must be processed before they can be processed or used. The traditional method mainly relies on manual processing with tools such as hand grinding wheels, which is not only low in efficiency, high in labor intensity, low in safety, but also prone to omissions, resulting in incomplete polishing. Some mechanical processing enterprises have begun to use shot blasting machines for polishing, but the shot blasting machine needs to add an additional container for holding small workpieces when processing smaller workpieces. Blocking or mutual blocking between workpieces, the blocked parts cannot effectively remove burrs, resulting in poor polishing quality.

[Summary of the invention] The utility model provides a drum polishing machine for the above problems.

This drum type polishing machine includes a bracket, a drum body and a motor, and is characterized in that a timing switch is installed on the bracket, and a motor is provided at the lower part of the bracket; the drum body is an inner hollow octahedron, and a stirring block is installed on the inner wall thereof There is a detachable inlet and outlet door on the top, and a locking beam is installed on the detachable inlet and outlet door through bolts. There is also a handle on the detachable inlet and outlet door; there are limit rings installed on both sides of the main body of the drum, and one end of the main body of the drum The support shaft and the bearing seat are connected by a flange, and the other end of the main body of the drum is connected to the drive shaft and the bearing seat through the flange, and the support shaft and the drive shaft are fixed on the bracket through the bearing seat; a large pulley is installed on the drive shaft, and the motor A small pulley is installed on the top, and the large pulley is connected with the small pulley by a belt.

The beneficial effects of the utility model: 1. It has the advantages of small size, light weight, low energy consumption, convenient operation and easy movement; 2. It solves the problems of low efficiency and high labor intensity of manual polishing; 3. Different sizes and thicknesses All workpieces can be polished and have a wide range of applications; 4. The workpieces collide with each other more violently in the closed drum body, which can effectively remove burrs; 5. The drum body is designed as an octahedron with an inner hollow. The stirring block drives the workpiece to roll, collide and rub continuously, improving the polishing efficiency and quality.

【Description of drawings】

Fig. 1 is the structural representation of the utility model

In the figure: 1. Bracket, 2. Bearing seat, 3. Support shaft, 4. Limit ring, 5. Flange, 6. Drum main body, 7. Stirring block, 8. Detachable inlet and outlet door, 9. Locking beam, 10, bolt, 11, handle, 12, transmission shaft, 13, large pulley, 14, timing switch, 15, belt, 16, small pulley, 17, motor.

[Specific implementation] Below in conjunction with accompanying drawing, the implementation of the present utility model is set forth as follows:

In Fig. 1, the drum polishing machine includes a bracket 1, a drum main body 6 and a motor 17, a timing switch 14 is installed on the bracket 1, and a motor 17 is provided at the bottom of the bracket 1; the drum main body 6 is an inner hollow octahedron, and a There are multiple mixing blocks 7 interlaced with each other. The main body of the drum 6 is provided with a detachable inlet and outlet door 8. The detachable inlet and outlet door 8 is equipped with a locking beam 9 through bolts 10. The detachable inlet and outlet door 8 is equipped with There is also a handle 11; the limit ring 4 is installed on both sides of the drum body 6, the left side of the drum body 6 is connected to the support shaft 3 and the bearing seat 2 through the flange 5, and the right side of the drum body 6 is connected to the flange 5 Transmission shaft 12 and bearing seat 2, support shaft 3 and transmission shaft 12 are fixed on the bracket 1 through bearing seat 2; large belt pulley 13 is installed on the transmission shaft 12, small belt pulley 16 and large belt pulley 13 are installed on the motor 17 Connect with small pulley 16 by belt 15.

Open the detachable inlet and outlet door 8, put the workpiece into the drum body 6, then close the detachable inlet and outlet door 8, insert the locking beam 9 into the limit circle 4 on both sides of the drum body 6, and fix it with bolts 10 Lock beam 9. During work, turn on the power supply, set the polishing working time by the timing switch 14, start the motor 17, and the motor 17 drives the small pulley 16 → belt 15 → large pulley 13 → drive shaft 12 → flange plate 5 → cylinder main body 6, cylinder The main body 6 drives the inner workpiece to roll, and the stirring block 7 can promote the inner workpiece to roll. Through the collision and friction between the workpiece and the collision and friction between the workpiece and the drum main body 6 and the stirring block 7, the burrs, sharp edges, rust and scale on the surface of the workpiece are removed.

Iron sand can be added to the main body of the drum 6 as needed to buffer the collision and make the polishing more efficient and thorough, especially suitable for thinner workpieces.
