Abstract

The utility model relates to mechanical engineering and can be used in the automotive industry for pressing a bearing into a thin-walled bushing followed by caulking, for example, in the manufacture of the upper pillar support of a car. The device is a spring-loaded plate, making a stroke in a vertical plane under the action of the press rod. The plate has spring-loaded punches for mounting bolts and bearings. A housing is fixed on the bearing punch, in the slots of which three embossments are movably mounted at an angle of 30 ° to the horizontal plane, which allows to reduce the vertical component of the caulking force. The embossers contact the rear ends with the inclined flat platforms of the “floating” ring installed in the plate with a radial clearance to ensure self-installation of the embossing unit along the outer ring of the bearing. 2 ill.

Description

The utility model relates to mechanical engineering and can be used in the automotive industry for pressing a bearing into a thin-walled bushing followed by caulking, for example, in the manufacture of the upper pillar support of a car.

A device [1] is known for pressing and caulking bearings, comprising a movable plate mounted on racks with spring-loaded rods for pressing bearings and bolts and a punch for pressing bearings, as well as a tool for caulking bearings.

The disadvantage of this device is that the chasing of the bearing is carried out by axial movement of the tool. At the same time, the thin-walled bearing sleeve, not possessing sufficient rigidity due to the presence of a step, is deformed under the action of significant axial forces, and with lesser forces, the bearing is undermined, which during operation of the assembled part leads to its play in the bearing sleeve.

The technical task of the utility model is to improve the manufacturing quality of car parts.

The technical result of the use of the utility model is to ensure reliable mounting and caulking of the bearing, the exclusion of its play and deformation of the bearing sleeve.

The specified technical result is achieved due to the fact that the device contains mounted on racks, with the ability to move under the action of springs, a plate with located on it

spring-loaded rods for mounting bearings and bolts and a punch for pressing a bearing, as well as a tool for caulking, and the device is equipped with a housing mounted on the rod of a punch for pressing in a bearing, which has three windows equally spaced around the circumference and made obliquely at an angle of 30 ° to the horizontal plane, in which are movably installed tools for chasing (chasing). At the same time, the rear ends of the embossments are in contact with inclined flat platforms of the “floating” ring installed in the plate with a radial clearance to ensure self-assembly of the embossing unit relative to the pressed bearing and to ensure uniform embossing at three points.

The angle of the embossments at 30 ° was chosen based on the fact that, with a larger value, the vertical component of the effort of engraving the bearing increases significantly, and at an angle less than 30 ° the stroke of the press increases.

Figure 1 shows a General view of the device in its original position.

Figure 2 shows a General view of the device in the final position.

The device comprises a plate 1, in which rods 2 and 3 are installed, spring-loaded with cup springs 4 and held by nuts 5. A rod 6 has a punch 6 for mounting the bearing 7. In the rod 3 there are punch 8 for pressing the bolts 9 (3 pieces). A housing 10 with movable coins 11 is installed on the rod 2. A ring 12 is mounted in the plate 1 with the possibility of moving in the radial direction. The plate 1 is mounted on the rolling pins 13 of the press plate and spring-loaded with springs 14 until it contacts the washers 15. A movable device 16 with a pin 17 is installed on the press plate for mounting the support 18 and bearing 7.

The drive of the device is a hydraulic press rod.

The device operates as follows. In the initial position, the plate 1 by the springs 14 is held in the upper position. The setting tool 16 extends to the operator. The operator establishes a support

18 and the bearing 7 on the finger 17, the bolts 9 into the holes of the support, retracts the device under the press rod and presses the buttons of the two-armed control panel. The press rod acts on the plate 1 and moves it to the bottom. The punch 6 by the force of the springs 4 presses the bearing 7 all the way into the ledge of the support sleeve, and the housing 10 closes on the fixture 16. The plate 1 moves further downward, compressing the spring package 4. The ring 12 with an inclined surface biases the embossments 11 towards the center, making caulking. At the same time, the punches 8 press-fit the bolts 9 by the force of the springs 4. The next command is to return the press rod to its original position. Plate 1 with all incoming parts under the action of the springs 14 is returned to its original position. The cycle is completed.
