Abstract
The utility model discloses a rotation coupling device for the oil channel system of a forging manipulator, which is characterized in that a rotation body is connected with a coupling sleeve by a bearing; the rotation body is capable of rotating in the coupling sleeve; the inner wall of the coupling sleeve is provided with two annular grooves which correspond to the two oil-channel outlets of therotation body; the coupling sleeve is also provided with two oil openings which are communicated with the two annular grooves; and a stop retainer ring is connected with a flange and the coupling sleeve by a bolt. The device can be applied to the oil channel mechanism of the similar system widely; and the device has simple structure and good effect.
Description
Technical field
The utility model belongs to oil circuit interconnection technique field in the hydraulic system, relates in particular to the swivel coupling device in a kind of forging operation oil way system.
Background technology
In the existing equipment as the forging equipment forging manipulator, clamping cylinder is also followed its rotation simultaneously in its structure when its clamp spinning movement is carried out, if the oil pipe that link to each other with oil cylinder this moment directly links to each other with oil cylinder, then the oil pipe wrapping phenomena can occur, cause abnormalities such as oil pipe explosion or leakage of oil take place in the work.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of swivel coupling device that can solve the oil pipe wrapping phenomena in hydraulic oil pipe system.
To achieve these goals, the technical solution of the utility model is that the swivel coupling device mainly comprises revolving body parts that are connected the oil cylinder bottom and the fitting sleeve parts that are enclosed within above it, there is bearing its inside, can make that revolving body is relative with fitting sleeve to be rotated, two oil circuits are arranged in the revolving body, link to each other with oil return opening with the oil cylinder oil-in respectively, two grooves are arranged in fitting sleeve inside, and at surface and groove opposite position opening, two mouthfuls can be regarded as one and be oil-in, another is an oil return opening, this two groove is also corresponding with the outlet of two oil circuits in the revolving body, therefore two hydraulic fluid ports just are equivalent to two hydraulic fluid ports of fitting sleeve in the oil cylinder, sealing prevents that with the sealing of YX circle oil is moving at the inside string in the fitting sleeve, avoids leakage of oil.Therefore also accompanying rotation of revolving body when oil cylinder rotate, because of fitting sleeve and the relative motion of swivel coupling energy, so oil pipe is connected on the fitting sleeve, and fitting sleeve does not change, thereby plays the effect of avoiding oil pipe winding in the oil circuit.
The utility model improves, and the sealing mechanism in the fitting sleeve encloses with YX, and opening is to the direction that oil pressure is arranged during installation.
The utility model further improves, and at the revolving body end face bolt hole is arranged, and can directly be fixed by bolts on the oil cylinder bottom surface, and is easy for installation.The swivel coupling bottom surface can be fixed on the device body with fixed mount, thereby can prevent better that fitting sleeve maintains static when revolving body rotates.
The beneficial effects of the utility model are as follows: when equipment was carried out spinning movement, oil cylinder rotated and oil pipe is not rotated, thereby has prevented the oil pipe wrapping phenomena, and then has also removed a series of problems (as leakage of oil, booster etc.) that cause because of wrapping phenomena; This device can be widely used in the oil circuit mechanism of class formula system, and simple in structure, result of use is good.

1-revolving body, 2-packing ring, 3-fitting sleeve, 4-adjust packing ring, 5-flange, 6 stop back-up rings 7, hydraulic fluid port 8, hydraulic fluid port
The specific embodiment
By shown in Figure 1, revolving body 1 is connected with fitting sleeve 3 by bearing, revolving body 1 can rotate in fitting sleeve 3, on the inwall of fitting sleeve 3, be provided with two annular grooves, this two annular groove is corresponding with two oil circuit outlets in the revolving body, also be provided with two hydraulic fluid ports 7 and 8 on fitting sleeve 3, this two hydraulic fluid port and two annular grooves connect, and stop back-up ring 6 is connected with fitting sleeve 3 with flange 5 by bolt.
Operation principle: when equipment was carried out action, revolving body 1 was followed oil cylinder and is rotated, and fitting sleeve 3 is fixed by stop-motion seat by stop back-up ring 6, prevents that it from rotating, and this moment, oil pipe was connected on two hydraulic fluid ports of fitting sleeve, and YX encloses good sealing effectiveness in the structure of the inside.
