Description

The invention relates to mechanical engineering, in particular, to pneumatic mechanical devices of impact action, and can be used for branding, riveting, hammering, punching, coreing and pressing

The purpose of the invention is to increase the impact energy and its adjustment at the expense of a change in the mass of the impactor and the force of compression of the springs.

FIG. 1 shows the pneumatic device in the initial position, the section; in figs 2 - the same, the position before the impact; in fig. 3 is a section through I-A-A in FIG. ten

The pneumatic mechanical impact device contains a hollow cylindrical body. 1, a pneumatic cylinder 2 coaxially mounted therein, a hollow rod 3 with a piston 4, and a cylindrical drummer 5 with a shank 6 located in the hollow rod 3, an air distributor 7 containing a spring 9 spring-loaded valve 9 and having holes 10 and 11. The device also has a locking mechanism mounted on hollow stem 3 for engaging with shank 6. For this, shank 6 has a collar 12. There is a locking mechanism in the two-arm vice 13 mounted on axles 14 on the hollow stem 3 and spring-loaded with ring springs 15. For tim work on motsilindre pneumatic grippers 2 are 16 and pushers 170 in the hollow cylindrical body 1, a work tool 18, the spring-loaded by a spring 19, and at the end of the housing 1, opposite

The working tool 18 has an axial bore 20. The pneumatic cylinder 2 is mounted in the housing 1 with the possibility of axial movement and filled with a radial collar 21, izgayuschim axial bore 22 and dividing the pneumatic cylinder 2 into two cavities 23 and 24 "Hollow rod 3 is installed in about TM hole 22 of the radial shoulder 21 and secured in the axial bore 20 of the housing 1 by a nut 25. The piston 4 forms in the cavity 24 of the pneumatic cylinder 2 working chambers 26 and 27 connected to the air distributor 7 by flexible air ducts 28 and 29 s. A series of axial bores 30, the device is equipped with guiding fingers 31 with a number equal to the number of axial bores 30 of the striker 5, the guide fingers 31 are fixed at one end on the radial collar 21E and others are installed in the alternate holes 30 of the striker 5. In the device there are also springs 32, their number is chosen equal to the number of guide pins 31 "The springs 32 are located on the guide pins 31, with one end in contact with the radial collar 21, and the other with the impactor 5. The device also has replaceable rods 33 for fixing it on the free the end face of the shank 6. Compressed air is supplied to the air distributor 7 via air line 34.

Pneumatic-mechanical percussion device operates as follows.

as well as the instrument used. When the spool 9 is working, it is carried out with water, by electric or manually

Formula iso In the initial position, the air ducts 34 and 29 are connected, and the compressed air enters the working chamber 27 of the pneumatic cylinder 2 (Fig. 1). When the spool 9 is moved to its working position, the air lines 34 and 28 are connected. Compressed air enters the working chamber 26 of the pneumatic cylinder 2, which together with the pushers 17 and Q grips 16 moves in the axial direction along the hollow rod 3, compressing the spring 32. The energy of the compressed air passes into the energy of the compressed spring 32, When the pneumatic cylinder 15 15 moves and compressing the spring 32 of the collet 12 of the stem 6, resting against one of the shoulders of the double-arm levers 13, holds the hammer 5. At the end of the stroke of the pneumatic cylinder 2 pushers 17, act on the shaft with the stem, Pneumatic percussion, with a cylindrical hub mounted in it a hollow rod with a piston, a cue drummer with a tailing shaft in the hollow stem, and a lockable, mechanically hollow stem on the hollow shaft Do you want to increase the energy of the adjustment due to the drummer and the strength of the but from the shoulders of the two shoulders levers 13, the latter are turned around the axes 14, thereby freeing the drummer 5 (Fig. 2). Under the action of compressed springs 32, the hammer 5 accelerates and, at the end of the stroke, strikes the working tool 18 ". When the valve 9 moves, the air lines 34 and 29 are connected to the initial position by the spring 8. Compressed air enters the working chamber 27 of the pneumatic cylinder 2, the latter with pushers 17 and grippers 16 are moved in the axial direction. In this case, the grippers 16, interacting with the drummer 5, return it to its original position. At the end of the reverse stroke of the striker 5, the two shoulders levers 13, compressed by the end springs 15, fix the drummer 5 in the initial position. In order to provide the necessary impact energy, a certain number of springs 32 are installed: two, four, six and TODO. The impact energy can also be changed by changing the mass of the impactor 5, while removing the replaceable rod 33. When performing various jobs, the device can be installed in automated assembly systems for performing various operations, and also used as a hand tool. When this is moved, the IP of the spool 9 to the working position can be carried out mechanically by a drive, by means of electromagnets or manually shank with shank Invention Formula  shank with shank  shank with shank Pneumatic mechanical device percussion, containing a hollow cylindrical body, a pneumatic cylinder, a hollow rod with a piston and a cylindrical drummer with a shank installed coaxially in it, accommodating: - in the hollow rod, an air distributor, a locking mechanism mounted on the hollow rod / joint - springs, which are concerned, in order to increase the impact energy and to adjust it by changing the mass of the impactor and the force of the preloaded spring, The axial bore is made at the end opposite to the working tool; the pneumatic cylinder is mounted in the casing with axial displacement and made with a radial collar having an axial bore and dividing the pneumatic cylinder into two cavities; the hollow rod is installed in the axial bore of the radial collar and fixed in the axial bore of the body , its pores i - him are formed in the cavity of the pneumatic cylinder working chambers connected to the air distributor, in the drummer a series of paired axial holes are concentrically made, and the device is equipped with guide your fingers to the number, equal to the number of axial perforations of the percussion fixed by one ends on the radial collar, and the other mounted in the axial orifices of the impactor, and interchangeable rods for 3: fastening at the free end of the shank, and the number of springs being equal to the number of guide pins are located on one for contacting one end with a radial collar, and others - with a drummer.
