Description

CNC automatic double-sided polishing machine

technical field

The utility model relates to a mechanical processing machine, in particular to a numerically controlled full-automatic double-sided polishing machine capable of automatically polishing two opposite planes of a hand tool.

Background technique

Before the invention of the utility model, the polishing and grinding technology of hand tools was backward, and it was completely done manually, and the labor intensity was very high. Due to the long-term monotonous and repetitive work, it was easy to cause fatigue to the workers and cause safety accidents, which had serious safety hazards. At the same time, a large amount of dust generated by polishing and grinding will cause serious pollution to the environment, and will cause hidden physical diseases to workers who have been engaged in production and processing for a long time, which is not conducive to the physical and mental health of employees and the long-term development of enterprises. At the same time, due to the above reasons, it has been difficult for enterprises to recruit a large number of employees engaged in polishing work. At present, manipulators are used to replace labor. Due to the high investment cost of manipulators and high quality requirements for workers, it is difficult for enterprises to accept it, and it is difficult to realize fully enclosed operations for manipulators, and it is still difficult to eradicate environmental pollution.

Detailed ways

As shown in Figure 1 and Figure 2:

The column 2 is installed in the middle of the bed 1, the lower end of the ball screw assembly 4 is connected to the column 2, the servo motor 5 is connected to the upper end of the ball screw assembly 4, and the ball nut 4-1 on the ball screw assembly 4 is connected to the vertical slide 3 , two (cylindrical) linear guide rails 6 are separated on the left and right sides of the column 2, and are arranged symmetrically. The linear bearing housing 6-1 on the two linear guide rails 6 is connected to the vertical slide plate 3; The side and the right side are connected, the driving wheel 7 is connected with the motor 8, the two throwing wheel assemblies 9 are respectively connected with the vertical slide plate 3 left and right, and the two tensioning wheel assemblies 11 are left and right, respectively connected to the left and right sides of the column 2 bottoms. The right sides are connected, and are respectively connected to the bed 1 through springs 18. Two driven wheel assemblies 12 are on both sides of the column 2 and connected to the bed 1. The abrasive belt 13 is connected to the driving wheel 7, the throwing wheel assembly 9, and the driven wheel assembly 12. and the tensioning wheel assembly 11 closed-loop connection, the throwing wheel cylinder 10 is connected with the throwing wheel assembly 9; (fully enclosed) the protective cover 15 is installed on the bed 1, and the dust collector 14 is connected with the rear of the bed 1; (automatic) The feeding mechanism 16 is installed in front of the bed 1 , and the workpiece 17 is discharged in the feeding mechanism 16 .

Description of the utility model application process:

The servo motor 5 controls the rotation of the ball screw on the ball screw assembly 4, drives the vertical slide 3 to move up and down through the ball nut 4-1, the vertical slide 3 drives the two throwing wheel assemblies 9 to move up and down, and the two linear guide rails 6 Guiding effect, two throwing wheel cylinders 10 respectively drive two throwing wheel assemblies 9 to move in the horizontal direction.

The two motors 8 respectively drive the two driving wheels 7 to rotate in opposite directions, thereby driving the abrasive belt 13 to rotate in the opposite direction. The tightness of the abrasive belt 13 can be adjusted by adjusting the inclination angle α of the tensioning wheel assembly 11 and the tension of the spring 18. For optimum polishing preparation.

Before the work starts, the vertical slide 3 drives the two throwing wheel assemblies 9 to be at the upper starting position of the polishing workpiece, and the two throwing wheel cylinders 10 push the two throwing wheel assemblies 9 to separate; the feeding mechanism 16 sends the workpiece 17 to be processed At the same time, the two throwing wheel cylinders 10 push the two throwing wheel assemblies 9 closer to the workpiece 17, so that the abrasive belt 13 forms a certain pressure on the polishing surface of the workpiece 17; the vertical slide 3 drives the two throwing wheel assemblies 9 to move downward to The lower end of the polishing surface of the workpiece 17 completes the polishing work; in order to make the abrasive belt 13 wear evenly in the polishing process so as to improve the service life of the abrasive belt 13, during the up and down movement of the two polishing wheel assemblies 9, the workpiece 17 also moves along the transverse direction of the abrasive belt 13 under the drive of the feeding mechanism 16, covering the width of the abrasive belt 13, and at the same time, the spring 18 also automatically compensates the tension of the tension wheel assembly 11; the feeding mechanism 16 Take back the workpiece 17 and send the next workpiece 17 to the processing position again; the next workpiece 1 repeats the above steps to complete the automatic polishing work.

The dust generated by polishing is inhaled by the dust collector 14 for centralized treatment.

The protective cover 15 is rotatably connected to the bed 1, which is convenient for opening and closing, and achieves a fully enclosed effect.
