Description

The invention relates to devices for disassembling tight joints of parts, in particular, for removing technological half rings from rubber-metal joints after vulcanization.

The rubber-metal hinge has a cylindrical-spherical shape with cylindrical connecting elements on both sides (two-bearing rubber-metal hinge). A layer of vulcanized rubber is glued to the outer and end landing surfaces of rubber-metal hinges, which is pressed on both sides by pressure cups (bushings) (see application RU No. 2008107486, IPC 8 F16C 7/00, 2008). Prior to vulcanization, technological half rings, which are in contact with pressure cups, determine the filling volume of vulcanized rubber and the shape of the end surfaces of the part are installed on two-way rubber-metal hinge on both sides. Together with the installed half rings, the rubber-metal joint is placed in the vulcanization mold. After the end of the vulcanization process, technological half rings must be removed. The connecting elements of the two-bearing rubber-metal hinge are made equally stepped on both sides, and the end sections have a larger diameter. And direct movement to remove the half rings is not possible.

Known manual removal of technological half rings using a screwdriver included in the ledges along the connector line of the half rings.

This method of removal is not technologically advanced and has a great complexity.

A device for removing parts containing a frame, a removable mechanism mounted on it with grippers (see patent RU No. 2261162, IPC 7 V23P 11/02, V23P 19/02, 2005).

The closest to the claimed technical solution (adopted as a prototype) in terms of essential features is a device for extracting a sector mandrel from a molded tire, containing a mechanism for extracting sectors of the mandrel, including a base, mounted on it rotary grippers by means of two-arm levers connected with each other and with the base by means of a common hinge, and a gripper drive (see patent RU No. 1561400, IPC 6 В29С 35/02, В29С 33/48, 1995).

The disadvantage of this device is the lack of technology and the inability to use to remove the half rings from the rubber-metal hinge, since the shape-forming profile of the half rings enters the formed rubber at a certain angle (e.g. 45 °) and half rings must be removed from both sides without deforming the product.

The task was to create a design of a device for removing technological half rings that meets the requirements of manufacturability, reliability, quality of the rubber-metal hinge and with less laboriousness.

This problem is solved in that in a device for removing parts containing a base with means for fixing the part placed on it, grippers in the form of two shoulders levers connected with each other and the base, the gripper drive, the means for fixing the part is made in the form of a lodgement, emphasis and grooves for placement of grippers in the removed parts, the levers are interconnected by means of a wedge mechanism, each lever is connected to the base with its axis, the gripper drive is made in the form of a pneumatic cylinder, and the grooves in the removed parts are made od angle to the workpiece, with which the

I’ll eat, and the ends of the levers opposite to the grips are placed in the grooves of the wedge mechanism made at an angle to each other with the possibility of translational movement.

In the inventive device for removing parts (technological half rings from a rubber-metal hinge) new features are: the implementation of means for fixing the details (rubber-metal joint with technological half-rings) in the form of a lodgement, emphasis and grooves in the removed parts made at an angle to the part from which it is being removed (technological half rings) for placement of captures; the levers are interconnected by means of a wedge mechanism, and with the base, each lever is connected by its axis; the gripper drive is made in the form of a pneumatic cylinder; the ends of the levers opposite to the grips are placed in the grooves of the wedge mechanism made at an angle to each other with the possibility of translational movement.

The inventive utility model is illustrated in the drawings:

Figure 1 - device for removing parts, front view;

Figure 2 - device for removing parts, top view;

Figure 3 - removable half rings, front view in section;

Figure 4 - removable half rings, side view.

The device for removing parts consists of a base 1, on which a lodgement 2 is mounted to accommodate a rubber hinge 3 with technological half rings 4 located on it on both sides and in contact with pressure cups 5 of the rubber hinge 3. The lodgement 2 is mounted on the base 1 with the possibility of its rotation on 180 °. The surface of the technological semirings 4, with cups 5 in contact with them, adjacent to the rubber-metal hinge 3 has a shape-forming profile, which must be obtained on the part after vulcanization, and determines the filling volume of the vulcanized rubber and the shape

end surfaces. After the vulcanization process is completed, the technological half rings 4 must be removed. To fix the rubber-metal hinge 3 on the lodgement 2, a stop 6 is provided and grooves 7 are made in the technological half rings 4 to accommodate the grippers 8 of the levers 9. The grips 8 are made on one side of the mirrored two-arm levers 9. The levers 9 are pivotally mounted on the axes 10, fixedly mounted on the base 1. The levers 9 are interconnected by means of a wedge mechanism 11, in the grooves 12 of which the ends of the levers 9 are located opposite to the grips 8. The grooves 12 of the wedge mechanism 11 are made at an angle to each other with the possibility of translational movement of the ends of the levers 9. The drive of the levers 9 with grippers 8 is made in the form of a pneumatic cylinder 13, the rod 14 of which moves the wedge mechanism 11 together with the levers 9.

A device for removing half rings works as follows.

The rubber-metal hinge 3 removed from the vulcanization mold with the forming half rings 4 is mounted on the lodgement 2 until it stops 6 so that the grooves 7 coincide with the grips 8 of the levers 9 and when the lodgement 2 moves towards the levers 9, the grips enter the grooves 7 of the half rings 4. When turning levers 9 using a wedge mechanism 11, moved by the rod 14 of the pneumatic cylinder 13, the grips 8 of the levers 9 move the half rings 4 at a certain angle (in the example of 45 °) to the axis of the rubber-metal hinge 3 and separate them from the rubber part of the rubber-metal ball ira 3. To remove the second pair of half-rings 4 rubber mount 3 is rotated through 180 °, without removing from the cradle 2, and repeating the execution of half rings removably as described above.

A device for removing technological half rings from a rubber-metal hinge has adaptability, reliability in working with less laboriousness. Rubber joint,

manufactured using such a device meets the quality requirements.

The technical result is achieved by making grips in the form of two shoulders levers, interconnected by means of a wedge mechanism, by placing grippers in grooves made at an angle in the removed parts.

The inventive device for removing parts can be manufactured on standard equipment from known materials using known technologies.
