Description

The utility model relates to the field of automobile transport, in particular, to the field of car service and can be used in the conditions of both a large and the smallest workshop for editing (repairing) steel disks of automobile wheels of mainly passenger cars. The proposed stand is designed for restoration of shelves and flanges of rims of stamped wheel disks with a diameter of 13 to 18 inches of domestic passenger cars Volga, Niva, Sobol, Gazelle, as well as foreign cars.

The well-known "Machine for editing wheels of automobile wheels" according to the patent of the Russian Federation for utility model No. 77187, IPC class B21B 3/02, published on 10/20/2008 Bull. No. 29 (1).

The dressing of disks on this machine is carried out by rolling using the correct rollers mounted on two carriages: two correct pressure rollers of the landing shelf and one correct roller at the edges of each wheel rim at the same time.

This machine contains installed on a common bed: an electric drive, a gearbox connected to a spindle mounted on bearings on a support and with a faceplate mounted on the spindle for mounting the wheel disk on it, as well as two carriages mounted on the desktop, each of which is equipped with on bearings, two regular rollers at an equidistant distance relative to the horizontal axis of rotation of the spindle with the possibility of simultaneous editing from the inner surface of the flanges of two rims of the wheel disk; the rotation axes of the right rollers are mounted in the horizontal plane of rotation of the spindle and at a predetermined angle to the axis of rotation of the spindle with the ability to move the right roller along its axis of rotation in the casing-pintles back and forth by a predetermined amount, and the desktop and carriages are mounted to move by screw mechanisms; while the carriages move perpendicular to the direction of movement of the desktop.

The disadvantages of this machine for editing wheels of automobile wheels according to the patent of the Russian Federation No. 77187 are:

1. The gearbox with high torque is used on the output shaft of the gearbox 790 N⋅m, the gearbox has a large weight and overall dimensions;

2. A high-power electric motor is used - 1100 watts;

3. In this regard, the machine bed has increased strength and rigidity, as well as high weight and overall dimensions.

The goal in the development of the proposed utility model is to create an inexpensive bench for dressing automobile wheels with improved performance characteristics, as well as weight, power consumption and dimensions at high rates of quality and accuracy of dressing of the rims of the rims and flange of the wheels of automobile wheels compared to the analogue.

The specified goal and technical result are implemented as follows.

The proposed stand for editing wheels of automobile wheels, like an analogue, contains installed on a common frame: an electric drive, a reducer connected to a spindle mounted horizontally on bearings on a support and with a face plate mounted on the spindle for mounting the wheel disk on it, as well as installed on the bed of the desktop, made in the form of a lower carriage mounted movably on two supporting guide pins, fixed motionless on the bed of the machine on supports in the horizontal plane parallel flax each other and with the lower carriage movably on these guide pins by means of a screw mechanism of the stand perpendicular to the longitudinal axis of the spindle; mounted movably on two support guide pins fixed motionlessly on the lower carriage in a horizontal plane parallel to each other and perpendicular to the direction of movement of the lower carriage - the left and right upper carriages with the possibility of moving each carriage with its own screw mechanism relative to the lower carriage along two support guide pins with the possibility of simultaneous editing with rollers fixed on each upper carriage by two rollers along the landing flange of the wheel disc and one correctly at the roller from the inner surface of the flanges of the two rims of the disk, while the axis of rotation of the right rollers are installed in the horizontal plane of rotation of the spindle and at a given angle to the axis of rotation of the spindle with the ability to move the correct roller along its axis of rotation in the casing-pinhole back and forth by a predetermined amount, and the desktop and carriages are mounted with the possibility of reciprocating movement by means of screw mechanisms perpendicular to the direction of movement of the desktop.

But unlike the known analogue, in the proposed stand on the lower carriage there is only one upper carriage, on which a guide roller is installed in parallel with the axis of movement of the lower carriage and in the horizontal plane of rotation of the spindle, and on this roller, in turn, a mounting unit for the correct rollers is installed , with the possibility of its rotation through 180 ° relative to the guide roller from one rim to another rim of the wheel disk.

As an analogue of the proposed stand for editing wheels of automobile wheels, you can take the machine according to the source of scientific and technical information (1).

The list of figures in the drawings.

In FIG. 1 shows the proposed stand for editing wheels of automobile wheels, a general view of the wheel disk mounted on the stand plate.

In FIG. 2 the same, general view of the disc without wheels on the faceplate.

In FIG. 3 same front view.

In FIG. 4 same, plan view.

The proposed stand for editing wheels of automobile wheels consists of the following units, assemblies and parts.

On a welded steel frame bed 1, made in the form of a horizontally arranged parallelepiped, a steel rectangular plate 2 is fastened, for example, 800 × 600 × 15 mm (Fig. 1). On the plate 2, with the help of several bolts with countersunk heads, a steel wall 3 is fixed and two steel rectangular supports 4 (Figs. 1 and 2) are fixed at a certain distance from the wall 3, intended for fastening on them in the horizontal plane of two supporting guide pins 5. A lower carriage 6 is mounted on the pins 5 with the possibility of moving along the guide pins 5 along the longitudinal axis of the stand and perpendicular to the longitudinal axis of rotation of the spindle 7 with the faceplate 8 (Fig. 2).

The carriage 6, mounted on the supporting guide pins 5, with the help of four sliding bushes has the ability to move back and forth relative to the wall 3 using a screw pair mounted on the wall 3 using the handle 9 (Fig. 1, 2). A gearbox 10 is mounted on the plate 2 of the frame body, comprising two worm gears connected in series and transmitting rotation to the spindle 7 from an electric motor installed inside the frame 1 and connected to the gearbox.

Thus, the gearbox 10 provides a spindle speed of approximately 9 revolutions per minute. On the upper surface of the gearbox 10 is a shelf for working tools.

A disk of a car wheel 11 is mounted on the faceplate 8 of the spindle 7, which is centered when a centering washer is installed on the faceplate and is attached (pressed motionlessly) to the faceplate 8 with six bolts 12 (Figs. 1 and 2).

In the housing of the frame 1 is installed a drawer 13 for tools and devices (Fig. 1). On the carriage 6 along its edges, two steel walls 14 are strengthened parallel to each other by means of several bolts with countersunk heads (Figs. 1 and 2), and in each wall 14 in the corresponding two holes are fixed two support guide pins 15 (Fig. 2) in horizontal plane and parallel to each other.

The upper carriage 16 is mounted on the supporting guide pins 15 with the possibility of moving on the pins 15 parallel to the horizontal axis of rotation of the spindle 7. On the upper carriage 16, a guide roller 17 is fixed (Fig. 3 and 4) in parallel with the axis of movement of the lower carriage 6 and in the horizontal plane of rotation of the spindle 7, intended to be mounted on it pivotally of the mounting unit 18 of the right rollers in such a way that the mounting unit 18 can rotate 180 ° relative to the guide roller 17 from one rim to another rim of the wheel disk but.

The upper carriage 16 is moved along the guide support pins 15 back and forth with a screw pair mounted on the wall 14 using the handle 19 (Fig. 3). A mounting unit for straightening the rollers 18 is pivotally mounted on the guide roller 17, on which, using a screw pair and a handle 20, it is possible to control the movement of the right rollers for each of the two rims of the wheel disk before the dressing process. After editing one rim of the wheel disk, it is enough to turn the attachment point of the right rollers 18 through 180 ° around the guide roller 17 and the node is located at the second rim of the wheel disk to edit it.

The proposed stand for editing wheels of automobile wheels works as follows.

On the faceplate 8 of the spindle 7 coaxially with the faceplate axis, the wheel disk 11 is mounted and secured with the centering disc. The lower carriage 6 and the upper carriage 16 were previously moved using screw mechanisms 9 and 19 along their supporting guide pins 5 and 15, respectively, out of operation the position in which the wheel disk 11 can be freely and unhindered installed and mounted on the faceplate 8.

Then, the upper carriage 16 is moved by means of a screw mechanism 9 to one of the rims of the wheel disk so that the correct rollers of the roller mounting unit 18 are brought closer to the wheel disk shelf and inner surface, for example, of the right wheel rim of the wheel disk, and with the help of screw pairs 19 and 20 without a gap tightly press the roller against the rim of the wheel disk (Fig. 1) and turn on the spindle of the stand, after which the right rim of the wheel disk is edited.

Then, using the screw pairs 19 and 20, the attachment point of the rollers 18 is withdrawn to the inoperative position and by turning the assembly 18 about the axis of the guide roller 17 through 180 °, the attachment point of the rollers is already installed, for example, at the left rim of the wheel disk.

Then, the left wheel rim is edited in the same technological order as the right wheel rim. Thus, separately editing one and the second rims of a disk of an automobile wheel is carried out.

The proposed stand differs from the well-known analogue in that at one operational moment the surface is machined only on one rim of the disk (left or right) from two rims of the wheel disk and the work of the operator of the stand is facilitated.

In addition, it allows the use of a gearbox with a lower output torque on the gearbox shaft, which leads to a significant reduction in the cost of the gearbox used, a decrease in its weight and overall characteristics, and ultimately leads to a decrease in the power of the electric motor used, the weight of the stand and its cost.

A prototype of the proposed bench for dressing wheels of automobile wheels called “Premier Grant” was made in Omsk at the Sibek enterprise in November 2015 and tested with a positive result in terms of quality of dressing and labor productivity. In the presented figures 1-4 to this application, the stand is shown after its manufacture.
