Abstract

The utility model provides a positioning mandrel device which comprises a positioning mandrel, wherein the positioning mandrel adopts an integral structure in which a connecting flange, a tapered journal and a threaded journal are arranged in sequence. A first elastic expansion sleeve and a second elastic expansion sleeve are arranged on the tapered journal, a rubber elastic sleeve is arranged between the first elastic expansion sleeve and the second elastic expansion sleeve, a gland nut is screwed on the threaded journal, an open-end pressure plate is arranged on the inner side of the gland nut, and the gland nut and the open-end pressure plate form a clamping mechanism. During use, two loop-type parts are respectively sleeved on the first elastic expansion sleeve and the second elastic expansion sleeve, the open-end pressure plate is placed in a required position, the gland nut is screwed, the second elastic expansion sleeve is expanded, the thickness of the rubber elastic sleeve is compressed, and the first elastic expansion sleeve is also expanded, so that the loop-type parts are clamped at the same time. According to the positioning mandrel device, through the arrangement of the rubber elastic sleeve, the first elastic expansion sleeve and the second elastic expansion sleeve can be expanded to clamp the two loop-type parts, and the two loop-type parts are clamped in one step, so that the processing efficiency is improved.

Description

A kind of positioning core axle device
Technical field
The utility model relates to the positioning core axle device of processing ring set class part.
Background technology
At present, at the cylindrical of grinding machine, lathe or Digit Control Machine Tool processing ring set class part, all be to adopt positioning core axle to cooperate with elastic expansion-sleeve, ring set class part is clamped.At every turn, can only process a ring set class part, working (machining) efficiency is low.Under present design means, also do not occur, once clamp the positioning core axle device of two ring set class parts.
Summary of the invention
In order to guarantee two ring set classes of reliable grip part, enhance productivity, the utility model proposes a kind of positioning core axle device.
For achieving the goal, the technical solution adopted in the utility model is: a kind of positioning core axle device, comprise positioning core axle, positioning core axle consists of as a whole by adpting flange, tapering axle journal, threaded journal successively, it is characterized in that: be provided with the first elastic expansion-sleeve, the second elastic expansion-sleeve at the tapering axle journal, be provided with the caoutchouc elasticity cover between the first elastic expansion-sleeve and the second elastic expansion-sleeve; Be installed with clamp nut in threaded journal, the clamp nut inboard is provided with the opening pressing plate, and clamp nut, opening pressing plate consist of clamp mechanism.
Beneficial effect: during use, two ring set class parts are enclosed within respectively on the first elastic expansion-sleeve, the second elastic expansion-sleeve, put into the opening pressing plate, screw clamp nut, the second elastic expansion-sleeve spreading, the thickness of caoutchouc elasticity cover is compressed, and the first elastic expansion-sleeve is spreading also, simultaneously two ring set class parts is clamped.The utility model by the caoutchouc elasticity cover that arranges, guarantees that the first elastic expansion-sleeve, the second elastic expansion-sleeve can both spreadings, respectively two ring set class parts is clamped; Once clamp two ring set class parts, improved working (machining) efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, further describe the utility model as follows: a kind of positioning core axle device, comprise positioning core axle 1, positioning core axle 1 consists of as a whole by adpting flange 1a, tapering axle journal 1b, threaded journal 1c successively, be provided with at the tapering axle journal and be provided with caoutchouc elasticity cover 3 between the first elastic expansion-sleeve 2, the second elastic expansion-sleeve 4, the first elastic expansion-sleeves 2 and the second elastic expansion-sleeve 4; Be installed with clamp nut 5 in threaded journal, the clamp nut inboard is provided with opening pressing plate 6, and clamp nut 5, opening pressing plate 6 consist of clamp mechanism.
During use, two ring set class parts 7 are enclosed within respectively on the first elastic expansion-sleeve 2, the second elastic expansion-sleeve 4, put into opening pressing plate 6, screw clamp nut 5, the second elastic expansion-sleeve 4 spreadings, the thickness of caoutchouc elasticity cover 3 is compressed, and the first elastic expansion-sleeve 2 is spreading also, simultaneously two ring set class parts 7 is clamped.
Innovation of the present utility model is: the caoutchouc elasticity cover is set between two elastic expansion-sleeves, realizes the spreading of two elastic expansion-sleeves, reach the purpose that clamps simultaneously two parts, thereby in the situation that guarantee reliable grip and enhance productivity.
