Description

The subject of the invention is an automatic machine for grinding the side surfaces of the blade of a dangerous razor.

Known machines for the same purpose with the use of two parallel grinding spindles mounted in the movable in the radial direction of the heads, and movable in the axial direction of the slide, drying the clip for razors. The grinding of the blades on these machines is done by manually mounting razors and manually checking the thickness of the blades.

The proposed machine allows you to fully automate the process of grinding the side surfaces of razors. This is achieved by the fact that the machine uses a magazine and an automatic revolving drum, on which sliders with sockets for securing razors are located, which receive a reciprocating movement from the distribution system associated with the machine measuring electromechanical device.

FIG. 1 shows a general kinematic diagram of a machine for grinding razors, side view; in fig. 2 is a section along A-A in FIG. one.

The machine has a horizontal turret drum with sliders 2, equipped with sockets for razor blanks 3, two grinding wheels 4, CiMOHTHpOBaHHbix on swinging plane of spindle headstock 5 perpendicular to their axes, loaded with weights 6 and connected by spring 7, controlled by lever 8 solenoid I switchgear in the form of a permanently vrashayusC from the electric motor 10 of the camshaft //, on which a single-toothed driving disk 12, turning a revolving drum /, and a cam shaft Raban 13, resulting in the carrier shy J4, soobshaet reciprocating movement of the sliders 2 and coupled through a system of levers and rods 15, 16 with the cam 17 controlling measuring devices with r1chazhnymi headstock 5.

The driver disk 12 and the cam drum 13 are connected to the camshaft 11 by means of a two-sided end clutch 18, which is moved through the lever 19 by an electromagnet 20, which controls No. 82341-2 -

It is equipped with a track switch that interacts with a revolving drum and a measuring device.

The measuring device, designed to measure the blade thickness during the grinding process, consists of two spring-pullable 22 and arm 4 extended by a cam P, supported by tabs 24 on the side surfaces of the blade and provided with a two limit contact 25.

 a revolving drum / magazine store 21 is located to feed the blanks to the slide blocks 2. When the machine is started up, the coupling 18 is in the extreme left position and connects the driving disk 12 to the camshaft //. The disk 12, interacting with my tooth. With the protrusion of the revolving drum, turns it one step.

The blank coming from the magazine into the slider is transferred when the revolving drum is rotated to a working position in which the roller of the slider 2 engages with the carrier 14.

At the same time, the track switch turns on the electromagnet 20. which moves the clutch 18 to the right by means of the lever 19 and connects the cam drum 13 to the camshaft 13. The cam drum 13 via the drive 14 communicates a reciprocating movement of the slider 2 with the razor located in it, which is polished with cylindrical surfaces grinding wheels 4. At each stroke of the slider 2, the carrier 14 through the system tg and the levers 15, 16 and 26 rotates the cam 17, as a result of which the levers 23 of the Control and Measuring Device approach each other. Measure the razor blade thickness. When a certain predetermined blade thickness is reached, the first contact 25 closes, turning on the electromagnet I, which turns the lever 8 and, releasing the spring 7, reduces the force of pressing the grinding wheels to the razor blade. Further grinding continues at a softer level until, when the final blade size is reached, the second contact 25 closes, which turns off the electromagnet 20, as a result of which the clutch 18 turns off the cam drum 13 and turns on the drive disk 12. The revolving drum revolves and the cycle repeats is. The polished razor falls in the next position of the turret drum.
