the lifting mechanism 10, on which the lever 13 with the handle 14 'and the thrust ball bearing 15 is mounted. The sleeve has a screw thread that allows the faceplate to be lowered until it touches the fixed plate. The ring-shaped track 16 of the fixed plate 7 passes in front of the ejector 11 into a different groove 17. Fixed, the plate is bolted to the machine (not shown).

Attachments 9 for attaching parts are installed in the cylindrical nests of the faceplate 8 and move vertically along the rails and pins 18. The fixtures 19 are pressed by springs 20 ft of the ring track of the bottom plate. The protruding part 21 of each fixture serves to _λ install the part along its central hole. Each device is equipped with interchangeable rings 22 and interchangeable fix. satators 23, allowing to drill blind holes on both sides in parts with different central landing 25 holes. The equilibrium of the nashpipe is maintained by means of spring-loaded balls (not shown) installed in a fixed plate. Fixing the position of the part under the Tools is carried out by> 30 spring-loaded cylindrical clamps. rum 24 with a conical end that engages in the hole in the faceplate of the corresponding table position. In the faceplate installed. spring-loaded pins (not shown) to translate the lever from left to right. The lever has a latch 25, which protects it from accidental movement when it is clamped in the left position. The table is equipped with a limiter for turning the faceplate in the opposite direction (not shown).

To ensure the drilling of holes located on different circles, two conductive plates are provided.

A device for drilling holes in the details is as follows. The part ^ mounted on the fixture 9 for fastening the details of the first position of the table, by turning the faceplate 8 is fed under the tools 2 of the multi-spindle head 1. At the same time, the lever 13 with spring pins (not shown) is translated, from the left position to the right, under the action of the released spring 26, the retainer 24 sinks into the hole of the faceplate 8, and the faceplate itself, • falling together with the rotating lever along the screw thread of the sleeve 12, touches the fixed plate 7. The head 1 with the tools comes down and the holes are drilled in detail to the faceplate 8 is preloaded sprung of conductor plate 5. After drilling and lifting of the head 1 with the plate 5 of conductor lever 13 via the handle 14 is translated to the left, and on the working device of the second table position is placed ^- detail. When translating the lever, the faceplate, rising with it up along the screw thread of the sleeve, departs from the bottom plate. The lever, pressing on the spring 26, brings the latch out of the hole of the faceplate. By turning the faceplate, the detail of the second position is brought under the tools, in which then the holes are drilled. Working pri-, aptitude first; position in front of the ejector 11 under the action of the spring 20 is lowered down and installed on it part with holes is released. After moving the lever to the left position on the working fixture of the third position of the table, the part becomes, which then turns the faceplate under the tools. At this time, the part with holes lying on the platform, interacting with the ejector, is removed from the table, the working device of the first position, having reached the installation position of the part, rises, the working device of the second position goes down before the ejector. Further operations are repeated.

Claims (1)

The invention relates to the field of trunking and can be used for drilling holes in control valve parts. A device for drilling holes with a rotary table consisting of a fixed plate with a lifting mechanism and a rotary faceplate with attachments for part 1 mounted on it is known. A disadvantage of this device. ow; rc low productivity due to the cost of manual labor for fixing the part and removing it from the table. In order to increase productivity, the described device is equipped with a tripper on the axis of rotation of the faceplate and connected with a lifting mechanism by a lever connected to a spring and a retainer with which the fixed plate is fitted, and the part attachments are spring-loaded and equipped with balls to interact with the groove made on the fixed plate FIG. 1 shows schematically the device, a general view; FIG. 2 shows a rotary table, section, FIG. 3 - table, plan view, fig. 4 - section A-A in FIG. 1. The device for drilling holes in the parts of the control valves contains a multi-spindle Gusku 1 with sliding spindles carrying the tool 2, a rotary TABLE 3. The multi-spindle head moves back and forth along the columns 4, on which is placed the underside of the conductor plate 5, retained on the board, retaining it. The rotary TABLE consists of a fixed PLATE 7, a rotary faceplate 8, fixtures 9 for fastening parts and a lifting mechanism 1O. On the fixed plate 7 are mounted kolnki 4, one of which serves as the axis of the fastening of the faceplate 8. On the same column fixedly the resetter 11. In the fixed plate 7 is mounted the sleeve 12 of the lifting mechanism 10, on which the mouth, arm 13 and the handle 14 and the stop ball bearing 15, the sleeve has a screw thread that allows the faceplate to be lowered until it touches the fixed plate. A tread-shaped track 16 of the fixed plate 7 passes in front of the ejector 11 and a different groove 17. Stationary. The plate is fastened on the machine with bolts (not shown). The attachments 9 for fastening the parts are mounted in the cylindrical sockets of the platen 8 and are moved in the vertical plane along the guide pins 18. The fixture balls 19 are pressed by the springs 20 ft of the ring track of the lower plate. The protruding portion 21 of each fixture serves to install the part through its center hole. Each device is equipped with different rings 22 and interchangeable latches 23, which allow drilling of blind holes on both sides in parts with different central mounting holes. The balance of the flange is maintained by means of a spring-loaded ball mounted in a fixed plate (not shown). Fixing the position of the part under the tools is carried out by a spring-loaded cylindrical retainer 24 with a tapered end, which falls into the faceplate hole of the corresponding position of the table. Spring pins (not shown) are installed in the mounting plate to move the lever from the left to the right position. The lever has a retainer 25 preventing it from accidentally moving when it is installed in the left position. The table is equipped with a rotation limiter of Shchash, in the opposite direction (not shown). To ensure the drilling of holes located on different circles, two conductor plates are provided. A device for drilling holes in the parts works as follows. The part is mounted on the fixture 9 for fastening the details of the position of the table, turning the Handle 8, is fed under the tools 2 of the multi-spindle head 1. The lever 13 under the spring pins (not shown) is translated from the left position to the right. Under the action of the released spring 26, the latch 24 falls into the opening of the faceplate 8, and the faceplate itself,. 01 starts together with a rotating lever on the screw sleeve 12, so788945 touches the fixed plate 7. The head 1 goes down with the tools and the holes in the part pressed to the faceplate 8 of the spring-loaded conductor 5 are drilled. After drilling the holes and raising the head 1 with the conductor plate 5, the lever 13 is shifted to the left position by means of the handle 14, and a detail is put on the working attachment of the second seat behind the table. When translating the lever, the faceplate, lifting together with it upwards through the screw threading of the sleeve, moves away from the bottom plate. The lever, pressing the spring 26, removes the retainer from the faceplate hole. By turning the faceplate, the detail of the second position is fed under the tools in which the holes are then drilled. Working first; helping first; The position in front of the ejector li is lowered down by the action of the spring 20 and the part with the holes mounted on it is released. After the lever is moved to the left position, the part becomes the working tool of the third table, which is then turned to the tools by turning the faceplate. At this time, the part with holes on the platform, interacting with the ejector, is removed from the table, the work tool of the first position, passed to the position of the part installation, rises up, the work tool of the second position in front of the gate valve goes down. Further, the operations are repeated.
