Description
Technical field
The present invention relates to mandrel clamping fields, more particularly, to a kind of fluid pressure type expanding arbor.
Background technique
Distending mandrel is commonly used to thin-wall circular tube, annulus and bucket class part, such fixture makes from inner hole of workpiece outward by work
Part clamps, thus the periphery and both ends of the surface of workpieces processing, being a little of distending mandrel only carries out clamped one time to workpiece, i.e.,
The processing that can carry out multiple processes, has been widely used in every field now.
However, workpiece different for internal diameter at present, the mandrel for the expansion for needing size different clamps it, when more
When changing part, it is necessary to replace fixture, virtually increase the working efficiency of labourer, reduce production efficiency.Moreover, utilizing
When the mandrel clamping workpiece expanded at present, different technique, such as turning and polishing need the of different sizes of chucking power
The mandrel of different expansions is replaced, it is time-consuming and laborious, seriously reduce processing efficiency.
Therefore, in view of the above technical problems, it is necessary to further solution.
Summary of the invention
In order to overcome the above problem, the present invention, which provides, a kind of is applicable in the liquid that internal diameter is different and processing technology is different
Pressure type expanding arbor.
A kind of fluid pressure type expanding arbor, comprising: oil pump 1, pressure reducing valve 2, pressure gauge 3, solenoid valve 4, oil cylinder 5, shaft coupling 6,
Connector sleeve 7, disk 8, sliding block 9 and elastic component 10, oil pump 1, pressure reducing valve 2, pressure gauge 3 and solenoid valve 4 by an oil line pipe according to
Secondary series connection, solenoid valve 4 and oil cylinder 5 are connected in parallel later, two branches of solenoid valve 4 respectively with 51 liang of 5 the inside piston rod of oil cylinder
The shoe cream room of side is connected, and piston rod 51, which stretches out after oil cylinder 5, to be connected with the connecting rod of disk 8 by shaft coupling 6, and connector sleeve 7 is from outside
The connecting rod of cylinder piston rod 51, shaft coupling 6 and disk 8 is arranged, disk be connected with connecting rod side end face be plane, with its phase
Pair end face be inclined surface, along the circumferential direction three sliding slots are arranged in trisection on the inclined surface side of disk 8, set in each sliding slot
There is a sliding block 9, the bottom surface of sliding block 9 is matched with the inclined surface of disk, and sliding block 9 is moved in sliding slot by sliding rail, elastic component
10 are arranged in sliding block 9 along the outermost side of disk radial direction.
In use, the pressure oil of oil pump 1 flow to solenoid valve 4 after pressure reducing valve 2, pressure gauge 3, by solenoid valve 4 to oil cylinder 5
The control of oil pressure in the shoe cream room of 51 two sides of internal piston bar controls the movement of piston rod 51, to control the shifting of disk 8
It is dynamic, clamping of the final mobile realization for controlling sliding block 9 to workpiece, wherein solenoid valve 4 is controlled by digital control system.
Advantageous effects of the invention are mainly as follows:
(1) pass through solenoid valve control oil pressure, the final accurate control for realizing disk connecting rod moving distance, so as to adapt to
The processing of different inner diameters workpiece, and adapt to requirement of the different processing technologys to workpiece clamp clamp force；
(2) solenoid valve is controlled using digital control system, only need to inputs the internal diameter of workpieces processing and required clamping force can be real
Existing workpiece is disposably accurately fixed, and no longer needs to replace fixture in process, to improve production efficiency
(3) elastic component is set on the outside of sliding block, prevents interior expansive force excessive and damages inner hole of workpiece surface quality.
