Abstract
The hydraulic clamping and rotating device is a set of clamping and rotating device which is provided for columnar workpieces, and can clamp and rotate the columnar workpieces in various diameter ranges by changing the specification of the elastic clamping body.
Description
Technical Field
The utility model relates to a hydraulic pressure presss from both sides tight slewer specifically is to provide one set of tight slewer that presss from both sides for the column work piece, through the specification of changing the elastic clamp body, can press from both sides tight gyration to the column work piece of multiple diameter scope.
Background
Most of the current columnar workpiece clamping and rotating modes of adopting a pneumatic chuck or a hydraulic chuck belong to rigid clamping, certain damage is caused to the surface of a workpiece, the clamping stroke is small, the transmission torque is small, the chuck of one specification cannot adapt to the requirements of various diameters, the universality is poor, and the replacement cost is high. With the development of industry and the demand of market environment, new structural forms must be innovated.
Disclosure of Invention
The utility model relates to a hydraulic clamping slewer of column work piece, the security is high, compatible good, the transmission moment of torsion is big, the device that the outward appearance uniformity is high.
The hydraulic clamping and rotating device consists of a driving gear, a rotating outer sleeve, a rotating inner sleeve, an oil way, a seal, a piston, an elastic clamping body and a bearing gland, and is characterized in that: the rotary outer sleeve is fixed, the oil cylinder piston displaces to enable the elastic clamping body to deform and extend inwards to clamp a workpiece, the drive gear rotates to drive the rotary inner sleeve to rotate, the clamped workpiece indirectly rotates, the surface of the workpiece cannot be damaged due to elastic clamping, and the transmission torque is large.
By adopting the scheme, the efficiency can be improved, the cost can be reduced, the labor intensity of workers can be reduced, the device is composed of common structural members, the structure is simple, the realization is easy, and the economic benefit is remarkable.
Drawings
FIG. 1 is a schematic view of the structure of the present invention
In the figure, the device comprises a driving gear 1, a driving gear 2, a rotary outer sleeve 3, a rotary inner sleeve 4, an oil path and a seal 5, a piston 6, an elastic clamping body 7 and a bearing gland.
Detailed Description
The rotary outer sleeve 2 is fixedly connected with equipment, the rotary inner sleeve 3 is arranged in an inner hole of the rotary outer sleeve 2, bearings are arranged at two ends of the rotary outer sleeve, a bearing gland 7 presses an outer ring of the bearing and is fixed on the rotary outer sleeve 2 through screws, a piston 5 is arranged in the inner hole of the rotary inner sleeve 3, an elastic clamping body 6 is arranged in two clamping blocks in the piston, a workpiece enters the inner hole of the hydraulic clamping rotary device, oil enters an oil inlet hole, the piston 5 moves towards one side, the elastic clamping body 6 is clamped by the clamping blocks in the piston, the elastic clamping body 6 deforms under pressure, the volume extends inwards, the workpiece is clamped, the driving gear 1 rotates to drive the rotary inner sleeve 3 to rotate, and the clamped workpiece rotates accordingly.
