(5) METHOD FOR MONITORING THE MEASUREMENT OF MEDIUM DIAMETER. THREAD 8 PROCESS. PROCESSING

one

The acquisition refers to the measurement technique, in particular, to the methods of active control of the dimensions of the parts. in the process of their processing on thread grinding machines.

The closest in technical essence to the present invention is a method for controlling the size of the average thread diameter in the process, which consists in placing the thread surfaces of the contact sensing element, transferring the controlled size to the sensitive element, and determining the amount of movement of the sensitive element jj In a known way, the contact element is designed in the form of tips 1.1

The disadvantage of the known method is the point contact between the controllable threaded surface and the groping element. Under active control conditions, this is the reason for the increased wear of the groping element, which limits the technological capabilities of the method.

The aim of the invention is to expand the technological capabilities of the method of controlling the size of the average diameter of the thread.

Claims (1)

This goal is achieved by the method of controlling the size of the average thread diameter during processing, which consists in placing a contact groping element on the surface of the thread, transferring a controlled size to the sensitive element and determining the amount of movement of the sensitive element as a contact sensing element. use a flexible element, cover them with several adjacent threads, and the transfer of a controlled size to a sensitive element is carried out This same flexible element, forming an infinite transmission by a flexible link. 3 .9 FIG. 1 shows a control diagram of the size of an average diameter of a thread; FIG. 2, view A of FIG. one; in fig. 3 shows the implementation of the method during processing. The method for controlling the size of the average diameter of the thread during processing is carried out as follows. On one of the supports 1, for example, a rotating center, of the thread-grinding equipment 2, a sleeve 3 with an external thread corresponding to a controlled thread is installed. Sleeve 3 serves as a reference. It can be fixed in the required position on the support 1. A flexible contact element of infinite length spans several adjacent threads of the sleeve 3 and connects the sleeve 3 with the sensitive element 5 to form a flexible coupling transmission between them. Then install the workpiece, part 6 and align the screw groove of the sleeve 3 and part 6 so that one is a continuation of the second, and the end of the sleeve 3 tightly pressed against the end of the part 6. At the same time between the thread-processing tool 7 and the contact. element 4 provides a dimension interval B satisfying the measurement conditions during processing. In this position, the sleeve 3 is fixed on support 1. During the machining of the part 6, the contact element k, rolling the thread, follows tool 7, not preventing the processing of the thread. Together, with the thread-forming tool 7, it moves along the part 6 and the sensitive element 5. The current value of the size of the average diameter of the thread is determined by the displacement of the sensitive element 5 relative to the part 6 in the radial direction of the thread by means of the measuring means 8. 5 checking the adjustment of the measuring system on the thread of the sleeve 3, on which the contact element 4 is at that moment. Based on the measurement results of the current size of the average diameter of the thread, and 6, the positioning of the thread-forming tool 7 is corrected. After obtaining the required size of the part 6, the contact element is returned to its original position on the thread of the sleeve 3. The finished part 6 is removed and the next is installed. This method provides an expansion of the technological capabilities of the control of threaded parts during processing. Claim Method The method of controlling the size of the average thread diameter during processing, consisting in TQM, that a contact groping element is placed on the surface of the thread, transferring a controlled size to the sensitive element, and determining the amount of its displacement, characterized in that , as a contact groping element, they use a flexible element, cover them with several adjacent threads, and the transmission of a controlled size sensing element th element is carried out with the same flexible element forming an endless flexible transmitting bond.
