Abstract

The invention relates to the machining of materials by cutting, in particular to universal adjustment tools for machining parts on CNC machines operating as part of flexible manufacturing systems. The invention makes it possible to shorten the changeover time of the device for processing a different nomenclature of parts. On the clamping element 3 in its lower part 17 there are placed a retaining ring 18, an anvil ring 19 and a packet of cup springs 20. A package of disc springs 20 is placed between the stop ring 19 and the flange 21 of the base element 3. The plate is filled in the form of a set of plane-parallel rectangular the upper 2 and lower 7.8 parts mounted on the base 9 with the possibility of relative displacement with the aim of forming with their ends 14 walls of T-shaped grooves. A hydraulic mandrel fixed in the CNC machine spindle fits to the clamping element 3, while the clamping element enters the inside of the mandrel hole, and with its end it compresses the package of the belleville springs 20, acting on it through the stop ring 19. This position of the clamping element 3 relative to the mandrel is fixed, after which the mandrel moves to the desired position according to the program, moving element 3 along the T-shaped grooves. In this position, the clamping element 3 is unlocked and it is by means of package The leaf springs 20 are fixed in the T-slot of the slab. 1 hp f-ly, 10 id. B P (L 1C ate

Description

The invention relates to the processing of materials by cutting, in particular, to uni-aerial adjustment tools for machining parts on CNC machines working on flexible production systems. j The aim of the invention is to reduce the changeover time of a device for processing a different item of files.

Fig, 4 - based: shement in the initial position; oig, 5 - the same, with the spring pack compressed; FIG. 6, the same, before its movement relative to the walls of the T- (the rib of the plate; FIG. 7 - (|; hem of the movement of the base element fa along the walls of the T-shaped groove of the plate; FIG. 8) to the working position; in Fig. 9 - pas lies B-B in Fig. 5; in Fig. 10 - section G-Y in Fig "6,

In the upper plane-parallel patterns of parts 1 - and 2 there are Phasing elements 3-5, designed for the base of the machining part My 6, the dimensions of which are given AND by the coordinates XqOf, in, Moving the executive element of the CNC machine (not are shown)

Upper 1 and 2 and lower 7 and 8 flat 11: opaque rectangular parts: are attached with relative displacement on the base 9 with fastening elements O and form a plate with T-grooves P

Between the base elements 3 and the T-shaped walls 1 1 there are always guaranteed gaps I and b.

The upper plane 12 of the plate is designed to accommodate the part 6,; J the lower plane 13 - to be mounted on the table of a CNC machine (not shown). The ends 14 of the upper 1 and 2 and lower 7 and 8 plane-parallel rectangular portions form the vertical walls T-ofijiasHoro of the groove 11, and the upper plane of the base 9-- its bottom 15, Groove 16 is the source) 1 m by element 3-5,

. On the lower part 17 of each base element 3-5 there is a retaining ring 8, a stopper is 19

and a packet of springs of springs 20. A pack of disc springs 20 is placed between the stop ring and the flange 21 of each base element 3-5. The mandrel 22 is designed to move the base elements 3-5, the base elements 3-5 are fixed in the mandrel 22 by means of the locking axis 23 with bevel C.

The device works as follows. ,

In the initial position in the CNC shaft of the CNC machine, for example, there is a hydraulic-mounted mandrel 22. In addition, the assembled clamping element, for example, the element 3, having a package of disc springs 20, the retaining ring 19 and the stop ring 18, is in the initial position. the machine moves to the loading position — to the groove 16; then, according to the program, fluid is supplied to the hydraulic cylinder cavity of the mandrel 22, which moves the locking axis 23 (FIG. 5) in the direction from the axis of the spindle, releasing the fitting hole of the base 22 the spindle with the mandrel 22 moves along the axis of the pins in the direction of the clamping element 3, pressing the mandrel 22 onto the stop ring 18 (FIG. 5), which, in turn, compresses the stack of springs 20 by a certain amount A from the middle plane of the T-shaped groove 11; Next, according to the program, the fluid pressure in the hydraulic cylinder of the mandrel is relieved, and the locking axis 23 under the force of the cup springs 20 is displaced towards the clamping element 3, wedging it with a bevel C along the corresponding counter surface, In this position, the pinch with the clamping element 3 moves along its axis in the direction opposite to the lower plane - the bottom 15 of the T-shaped groove 11, retaining some guaranteed clearance H between the middle plane of the T-shaped groove II and by the stop ring 9 (fig. b), and further along the program moves along the T-shaped grooves 11 to the working position necessary to base the part 6 and form the coordinate system Y of the part 6, - the core is fed again to the hydraulic system

22, with the locking axis 23 (FIG. 9) moving away from the clamping element 3, and it, released from the mandrel 22, is fastened in this position (FIG. 8) and in The T-slot II of the device, and the spindle moves along its axis, releasing the clamping element 3, and then moves to the loading zone — the groove 16 for repeating the cycle in order to install the remaining clamping elements 4 and 5.

Claims (2)

1. Device for installation of parts, made in the form of slots, in T-shaped grooves of which flanging elements are arranged in two mutually perpendicular directions, differing in the fact that, in order to reduce changeover time, each clamping element is fitted with axial movement by the thrust ring and placed between the flange and the thrust ring by a packet of disc springs, while the flange of the clamping element is designed to interact with the bottom of the slot-like slot you, and the upper end face of the thrust ring - with the plane of the T-shaped slot opposite its bottom. 2. The device according to A.1, about tl and is that. The plate is made composite in the form of a base (Upper and lower plane-parallel rectangular parts, while the upper and lower parts are installed on the base with the possibility of relative displacement and are intended to form the ends of the vertical walls of the T-shaped grooves of the plate.
