Description
Technical Field
The invention relates to an eccentric bearing turning clamp device.
Background
The eccentric bearing developed by our factory has been changed from trial production to mass production. Although the clamp for the eccentric turning process in the turning process can meet the requirement of machining precision, the clamp is designed for machining on a common lathe, and an operator with large turning amount needs to feed and measure the tool setting for many times because the machined raceway and the inner diameter of the existing clamp are eccentric. Then the outer raceway or the inner diameter of the vehicle can be machined, the outer raceway or the inner diameter of the vehicle can be disassembled, the opening is expanded by using a tool, and the workpiece is taken down. The processes are repeated so as to install, clamp and align. The whole operation process is basically manual operation. It is seen that the labor intensity is great. The processing efficiency of the common lathe is obviously lower than that of the special lathe, and the defects of the common lathe fixture need to be correspondingly improved so that the common lathe fixture is suitable for being used on the special lathe.
Disclosure of Invention
The invention provides a turning clamp device for an eccentric bearing, aiming at overcoming the defects of the prior art.
The technical scheme of the invention is as follows:
a turning clamp device for an eccentric bearing comprises a tire body, a disc, a pull rod, a clamping tire, a positioning pin, a positioning ring and a connecting cylinder; the disc, the pull rod, the clamping tire, the positioning pin, the positioning ring and the connecting cylinder are arranged in the tire body; the positioning device comprises a disc, a connecting cylinder, a pull rod, a positioning ring, a clamping tire, a positioning hole, a positioning pin and a positioning hole, wherein one end of the pull rod is inserted into the disc, the disc is fixedly arranged on the tire body and the connecting cylinder, the positioning ring is fixedly arranged on the end surface of the connecting cylinder to realize axial positioning of a workpiece, the clamping tire is fixedly arranged at the end part of the tire body, the positioning pin is arranged in the groove at the end part of the clamping tire, the positioning pin is inserted into the positioning hole on the outer peripheral surface of the workpiece, and a gap is reserved between the positioning pin and the clamping tire.
Compared with the prior art, the invention has the following effects:
the invention has reasonable structure and appearance size design, compact structure, simplicity and practicability. The precision of the product of the die is verified to meet the requirement through actual processing, and the production requirement is met. The improvement of the clamp is verified through experiments, so that the production efficiency can be improved, and the product quality can be ensured. The operator has simple processing and is very beneficial to mass production. Meanwhile, the clamp is a special lathe clamp, and the standardization and serialization of the clamp are greatly facilitated.
Drawings
FIG. 1 is a schematic view of the present invention;
FIG. 2 is an enlarged view of the alignment pin and tire clamp connection of the present invention.
Detailed Description
The first embodiment is as follows: the present embodiment is described with reference to fig. 1 to 2, and an eccentric bearing turning jig device of the present embodiment includes a carcass 1, a disc 2, a pull rod 3, a clamping tire 5, a positioning pin 6, a positioning ring 8 and a connecting cylinder 9;
the disc 2, the pull rod 3, the clamping tire 5, the positioning pin 6, the positioning ring 8 and the connecting cylinder 9 are arranged in the tire body 1;
the utility model discloses a tire clamping device, including connecting cylinder 9, locating pin 5, disc 2, locating ring 6, locating pin 6, disc 2, locating ring 8, locating ring 6, locating pin 6, locating hole, locating pin 6 and clamp child 5, the disc 2 is in the cartridge, disc 2 fixed mounting is in on matrix 1 and the special section of thick bamboo 9, locating ring 8 fixed mounting is in the terminal surface of connecting cylinder 9 realizes the axial positioning to work piece 10, clamp child 5 fixed mounting be in the tip of matrix 1, the locating pin 6 is arranged in the recess of clamping child 5 tip, and the locating pin 6 cartridge leaves the clearance between locating pin 6 and the clamp child 5 on the outer peripheral face of work piece 10.
The distance between the positioning pin 6 and the upper surface of the clamping tire 5 is delta 1-0.2-0.5, and the distance between the positioning pin 6 and the left side surface of the clamping tire 5 is delta 0.2-0.5.
The gap is designed, the workpiece is clamped freely, and the machining efficiency is improved.
The second embodiment is as follows: the present embodiment is described with reference to fig. 1 to 2, and the carcass 1 of the present embodiment is fixedly mounted on the carcass fixing disk by the carcass fixing bolt 4. The rest is the same as the first embodiment.
The third concrete implementation mode: the present embodiment is described with reference to fig. 1 to 2, in which the other end of the tie rod 3 is screwed on the carcass fixed disk, and the surface of the tie rod 3 is a threaded surface. The rest is the same as the first embodiment.
The fourth concrete implementation mode: the present embodiment will be described with reference to fig. 1 to 2, and the connecting cylinder 9 of the present embodiment is mounted on the carcass 1 by the disk fixing bolt 7. The rest is the same as the first embodiment.
The fifth concrete implementation mode: the present embodiment is described with reference to fig. 1 to 2, and the axes of the carcass 1, the disc 2, the tie rod 3, the positioning ring 8, and the connecting cylinder 9 of the present embodiment are collinear. The rest is the same as the first embodiment.
The working principle is as follows:
the pull rod 3 moves rightwards under the action of the oil cylinder to cause the clamping tire 5 to expand, then a workpiece is loaded into the clamping tire 5 by hand, after the end face of the workpiece abuts against the positioning ring 8, the tire body 1 moves leftwards under the action of the oil cylinder to clamp the workpiece, the positioning surface of the workpiece is the positioning ring 8, the inner diameter of the tire body 1 is uniformly clamped to clamp the outer diameter of the workpiece, and the machine tool automatically feeds to process the workpiece.
The present invention has been described in terms of the preferred embodiments, but it is not limited thereto, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention will still fall within the technical scope of the present invention.
