Description

Steel ball classifying and screening device

Technical Field

The utility model relates to the technical field of steel ball production, in particular to a steel ball classifying and screening device.

Background

The steel ball is the most important component of bearing, also the rolling element that the bearing trade used the most, and the steel ball is consequently the processing error after production, and the size of steel ball is uneven, and some sizes are too big, and some sizes are undersize, only rely on the naked eye to be unable separately, and it is common to use the screen tray, will fall on the screen tray, manual rocking screen tray, let the big screen tray of leaving of size, the small size falls, generally need use the screen tray of big net and the screen tray of little net to carry out twice screening operation, and manual labor intensity is big, inefficiency.

Disclosure of Invention

In order to solve the problems that the existing steel ball screening operation needs to consume a large amount of manual labor and is low in efficiency, the utility model provides the steel ball classifying and screening device which can greatly save the manual labor and improve the screening efficiency.

The technical scheme is as follows: the utility model provides a steel ball classifying and screening device, its includes the screen tray, its characterized in that, the screen tray includes two and installs in the screening box, install two roating seats of arranging from top to bottom on the inner wall of one side of screening box, screen tray one side pass through the pivot with the roating seat is connected, two the screen tray opposite side passes through the riser to be connected, the drive box is connected to the screening box, install the motor that the level was arranged in the drive box, install the cam plate on the output shaft of motor, the diaphragm is connected in the riser outside, the diaphragm bottom support in cam plate, top install two at least first go-between, drive box top internally mounted have two at least with the second go-between that the first go-between corresponds, first go-between with the second go-between passes through the spring coupling that both ends band hook, the mesh size on the screen tray of upper strata is greater than the mesh size on the screen tray of lower floor.

The screening box is further characterized in that a ball inlet is formed in the top of the screening box body, a ball inlet hopper is arranged at the ball inlet, and an openable box door is arranged on the front face of the screening box body;

the screening box body and the driving box body are provided with communicated gaps, and the gaps are larger than the up-and-down movement area of the transverse plate;

four springs are arranged;

the side wall of the driving box body is provided with a limiting groove, and the end part of the transverse plate is provided with a limiting block movably clamped in the limiting groove.

After the screening device is adopted, the steel balls pass through the upper layer screening disc to screen, the larger size of the steel balls are reserved on the upper layer screening disc, the rest of the steel balls fall on the lower layer screening disc, the smaller size of the steel balls are reserved, the steel balls with the required size are driven by the motor to swing to enable the screening disc to vibrate up and down, so that screening operation is completed, operators only need to perform ball pouring and ball collecting operation, labor intensity is greatly reduced, the synchronous vibration of the upper layer screening disc and the lower layer screening disc is equivalent to that the screening operation can be completed through one-time screening operation, and screening efficiency is improved.

Detailed Description

See fig. 1, fig. 2, fig. 3, fig. 4 shows, a steel ball classification sieving mechanism, it includes sieve tray 1, sieve tray 1 includes two and installs in screening box 2, install two roating seat 3 that arrange from top to bottom on the inner wall of one side of screening box 2, sieve tray 1 one side is connected with roating seat 3 through the pivot, sieve tray 1 can use the pivot to swing from top to bottom as the center, two sieve tray 1 opposite sides are connected through riser 4, screening box 2 connects drive box 5, install the motor 6 that the level was arranged in the drive box 5, install cam plate 7 on the output shaft of motor 6, riser 4 outside is connected diaphragm 8, the breach 16 of intercommunication has been seted up on screening box 2 and the drive box 5, breach 16 are greater than diaphragm 8 up-down motion's region, diaphragm 8 bottom support is in cam plate 8, four first go-between 9 are installed at the top, the inside second go-between 10 that correspond with first go-between 9, first go-between 9 and second go-between passes through the couple 11 and connect the drive plate 7, can jack-up the mesh tray 1 with the size of screen tray is realized with the rotation of the upper and lower mesh tray 1 when the screen tray of the size of the upper and lower drive plate 7, the size of the screen tray is connected through the lift up through the coupler 7, the upper and the size of the upper-down of the motor of the drive plate is realized.

The top of the screening box body 2 is provided with a ball inlet, a ball inlet hopper 12 is arranged at the ball inlet, the front of the screening box body 2 is provided with an openable box door 13, all steel balls enter from the ball inlet hopper 12, firstly fall onto a screen disc at the upper layer, after vibration screening, the steel balls with bigger sizes are left, the steel balls with smaller sizes fall down smoothly and enter onto the screen disc at the lower layer, after vibration screening, the steel balls with smaller sizes fall down, the steel balls meeting the requirements are left, and a material receiving disc can be placed below the screen disc at the lower layer.

The limiting groove 14 is formed in the side wall of the driving box body 5, the limiting block 15 movably clamped in the limiting groove 14 is arranged at the end part of the transverse plate 8, the limiting effect of the transverse plate 8 is achieved, the transverse plate cannot swing left and right, only can swing up and down, up and down reliable vibration is finally achieved, and screening is completed.
