(54) DEVICE FOR TWO-SIDED SLEEVE STRESSES 'The invention relates to mechanical assembly, in particular for double-sided press-fit of bushes, and can be used when pressing bushes on parts having curved ends, for example, bicycle handlebars.

A device for double-sided pressing bushings on a part containing symmetrically mounted on the base and mounted on the same axis of the pressing head, lodgements for laying the ends of the part and clamping mechanisms [1].

The disadvantage of this device is that when napressovka bushings on the part, the ends of which are bent and have deviations in angle due to different elastic springs after bending, the reliability of simultaneous two-sided mounting of the bushings on the ends of the part is not ensured, since all the mechanisms of the device are rigidly installed one by one axis.

The purpose of the invention is to increase the reliability of pressing bushings ‘onto a part with curved ends made, for example, of an elastic material.

This goal is achieved due to the fact that the device containing the pressing heads located on the base, lodgements for the ends of the parts and clamping mechanisms, is equipped with platforms mounted on the base and pivotally attached at one end thereof, while the pressing heads, lodgements and clamping mechanisms mounted on platforms.

In FIG. 1 ’shows a device, a general view in plan; figure 2 - section aa in figure 1, * in fig. 3 - section BB in figure 1, ‘in figure 4 - · section BB in figure 1; in FIG. 5 - section

GG in figure 1.

The device comprises platforms 2 installed on the base 1, one ends of which are pivotally fixed to the base by means of axles 3 pressed into it 25, and the second ends are freely supported on rollers 4 placed on the axes 5 in the grooves of the base. On each platform, a lodgement 6 with a longitudinal groove 7 for. 30 laying the ends in a bent having assembled 837726 my parts, a clamping mechanism made in the form of a power cylinder 8 with a rod 9 connected to a pivot arm 10 placed in a vertical groove of the tool box 6. In addition, a pressing head containing - * power cylinder is fixed on each platform 11 with rods 12 connected to a carriage 13 having a socket for laying a press-fit sleeve. The axes of 3 platforms are placed so that they coincide with the vertices of the corners of the bend of the ends of the assembled part.

The device operates as follows.

In the initial position, the clamping heads of the levers 10 are raised, which 15 is provided by air supply to the piston cavities of the cylinders 8, i.e. the rods 9 of the cylinders 8 are in the lower position, and the rods 12 of the cylinders 11 are diverted together with the carriages 13 20 from the lodgements 6. The sleeves 14 are laid in the slots of the carriages 13, and the ends of the other assembled part 15 (steering wheel) manufactured in the grooves 7 of the lodgements 6 flexible __ from the pipe. If there is a difference in the angles of the platforms 2 and the bent ends of the part 15 when laying its ends in the grooves 7 of the cradles 6 due to the articulated installation of the platform on the basis of the 1 axis of symmetry 30 of the platforms and the ends of the part 15 are combined, i.e. platforms 2 are rotated at the required angle to the desired side ^ under the action of the ends of the installed part 15. The ends of the part 15 are stacked in 35 grooves 7 of the tool holders 6 until they stop in the carriage 13. After that, air is supplied to the rod cavities of the clamping cylinders 8, rods 9 of which the levers 10 are turned, which by their means themselves clamp simultaneously the ends of the parts 15 in the grooves of the lodgements.

One of the levers 10 is made with a shank, which includes in the working position a pusher of a three-way valve that supplies air to the piston cavities of the press-fit cylinders '11, the rods 12 of which begin to move the carriages 13 with the bushings 14, two bushings 14 are pressed simultaneously onto the ends of the part 15. After mounting, the rods of cylinders 8 and 11 are returned to their original position, and the assembled parts are freely removable.

This design of the device allows you to press two parts simultaneously on another part, made flexible, the ends of which are located at an angle to the axis and have a deviation in angle during manufacture, for example, the assembly of handles with a bicycle handle ·.

Claims (1)

MY part, the clamping mechanism, made in the form of a power cylinder 8 with a rod 9 connected with a pivoting lever 10 placed in the vertical slot of the cradle 6. In addition, on each platform a pressing head is fixed, containing the power cylinder 11 with rods 12, connected with a carriage 13 having a socket for laying the pressed-in sleeve. The axes of the 3 platforms are placed so that they coincide with the vertices of the corners of the bend of the ends of the assembled part. The device operates as follows. In the initial position, the clamping heads of the levers 10 are raised, which is ensured by supplying air to the piston cavities of the cylinders 8, i.e. the rods 9 of the cylinders 8 are in the lower position, and the rods 12 of the cylinders 11 are retracted together with the carriages 13 from the cradle 6. In the sockets of the carriages 13 there are pressed-in sleeves 14, and the grooves 7 of the cradles b put the ends of the other assembled part 15 (roll) made flexible of pipe. When there is a difference in the corners of the platforms 2 and the bent ends of the part 15, when its ends are placed in the grooves 7 of the cradle b due to the hinged installation of the platform on the base of axis 1 of the platforms and the ends of the part 15 are aligned, i.e. the platforms 2 are rotated to the desired angle in the desired direction, well, under the action of the ends of the installed rods 15. The ends of the part 15 are placed in the slots 7 of the cradle 6 until they stop in the carriage 13. After that, air is fed into the rod cavities of the cylinder 8, the rods 9 of which turn the levers 10, which at their own clamp at the same time the ends of the parts 15 in the slots of the cradle. One of the levers 10 is made with a shank that includes, in the working position, a pusher of a three-way valve providing air supply is the piston cavities of the pressing-in cylinders 11, the rods 12 of which begin to move the carriage 13 with the sleeves 14, two press-fittings 14 are simultaneously pressed onto the ends of the part 15. After pressing the rods of the cylinders 8 and 11 back to their original position, and the assembled parts are freely removed. This design of the device allows the pressing of two parts at the same time onto another part, made flexible, the ends of which are angled to the axis and have a deviation in the angle during manufacture, for example, assembling handlebars with a steering-bicycle. Apparatus of the Invention Device for two-sided pressing of sleeves onto the ends of a part, comprising press-fit heads symmetrically located on the base, cradles for the ends of the part, and clamping mechanisms, characterized in that, in order to increase the reliability of the press-fit sleeves on the part with angled ends, it is equipped with a platform, mounted on the base and pivotally fixed to it by one end, while eapressovoe heads, cradles and clamping mechanisms mounted on the platforms.
