Description

The invention relates to a machine tool industry and can be used on profile machines. The grinding head of a profile-grinding machine is known, which contains a drive made in the form of a worm gearbox, on the output shaft of which a crank-connecting rod mechanism is mounted, a carriage with a grinding wheel mounted on guides, the rotation of the electric motor is transmitted to the gearbox and then the curve is drawn. -accessible movement of carriages yi with a grinding wheel, which performs machining of part ij. During dressing the grinding wheel it is necessary to stop the carriage at the bottom, i.e. at the bottom dead center of the crank. In this position, the primer mechanism diamond carries out the PROCESS straightening. Accurately stopping the carriage in the edit position is very difficult due to the high speeds and masses of the moving parts. The aim of the invention is to improve positioning accuracy. The goal is achieved by the fact that the grinding head of a profile grinding machine, containing a drive mechanism with one bearing and a carriage of a spin wheel, is equipped with an overrunning clutch installed between a curved spike and the axis of its drive, and a brake for changing the torque value of the idling overrunning clutch, jSacon on the axis crank mechanism. At 4ng. Figure 1 shows the design of the grinding head; FIG. 2 shows the position of the connecting rod at the moment when the electric motor is turned off. The head contains the housing 1, the electric motors 2 and 3 of the carriage drive and rotation of the grinding wheel. In the housing 1 there is a gearbox consisting of a screw 4 and a worm wheel, 5, on the end of the shaft of which there is an overrunning clutch 6 bearing a spike 7, a connecting rod 8, a brake 9, for example, a friction clutch, with an adjusting screw 10. A connecting rod 8 is connected to a round 11, on which a grinding wheel 12 is mounted. On the body 1 there is a sensor 13 and on the crank there is a 7 petal 14. On the base of the body there is a device for straightening circle 15 with diamond diamond tool 16. The grinding head works as follows. The rotation of the electric motor 3 is transmitted by a belt drive to the grinding wheel 12. The rotation of the electric motor 2 is transmitted to the worm 4, then to the worm gear 5 and through the overrunning clutch 6 to the crank 7, the connecting rod 8 and the carriage 11. The carriage 11 performs a reciprocating movement along its guides. When commanding the motor to stop, it is turned off by the sensor 13. Petal 14 is installed so that the drive is detuned in an area that does not prevent the carriage from free-falling under its own weight (Fig. 2). After the drive is stopped, the overrunning clutch 6 does not prevent the crank 7 from turning freely in the direction of rotation of the drive and the carriage is lowered under its own weight, turning the crank 7 on the worm gear shaft 5. Reaching the lower extreme position the carriage stops. In the process of free movement of the carriage and the crank rotation associated with it, the position of the carriage relative to the teeth of the worm wheel is shifted, and consequently, the cycle loads on the worm gear teeth change. Such a shift occurs at each stop of the grinding head, which leads to uniform loading of all drive elements. The lowering speed of the carriage 11 is regulated by the screw 10 of the brake 9. When the drive is turned on, the overtaking is activated, the clutch 6 and the carriage 11 are rigidly engaged with the drive. With each remains -. The carriage 11 is in the lower position under the force of gravity, the overrunning clutch can be made in the form of a ball, ratchet, etc., and the brake - electromagnetic, pneumatic, etc. The application of the proposed grinding head increases the durability of the drive by uniformly distributing the load on all the transmission elements, and also increases the positioning accuracy of the carriage in its lowest position.
