Description

The multistation clamping device
Technical field
The utility model belongs to a kind of clamping device, is specifically related to the multistation clamping device.
Background technology
Clamping device is widely used in manufacturing.Be mainly used in clamping and the location of workpiece, so that workpiece obvious displacement does not take place adding man-hour, thereby improve machining accuracy.Application number is: 201110003039.5 disclose a kind of clamping device, comprising: axostylus axostyle, nut, collet and left and right sides tapered sleeve, and by tightening or unclamp nut, thus extruding or unclamp collet and realize the clamping of workpiece and unclamp.
Though this clamping device can satisfy the clamping demand of workpiece to a certain extent, but in actual use, still have the following disadvantages: 1, operation wastes time and energy 2, can only once clamp a workpiece or can only the single position of workpiece be clamped, efficient is low.
Summary of the invention
The purpose of this utility model is to provide a kind of time saving and energy saving and multistation clamping device that efficient is high.
For achieving the above object, the technical solution of the utility model is: a kind of multistation clamping device is provided, comprises matrix, rotating shaft and clamping device, described rotating shaft laterally runs through matrix; Described rotating shaft is provided with cam; Described cam contacts with clamping device; Described clamping device is positioned at matrix; Described clamping device comprises elastic jacket, expand body and slip cap, and described elastic jacket contacts with bloated body; Described bloated body passes slip cap; Described bloated body comprises pedestal, screw rod and bloated piece, and described screw rod one end embeds in the pedestal fixed with pedestal, and other end axially-extending goes out pedestal and bloated piece is fixed; Described bloated piece is positioned at elastic jacket and is used for strutting elastic jacket; Described slip cap and matrix are hinged; Be provided with spring in the described slip cap; One end of described spring is fixed in the slip cap, and the other end contacts with bloated body; The parallel placement arranged side by side of a plurality of described clamping devices is arranged in the described matrix; Described rotating shaft is provided with a plurality of cams and the corresponding contact respectively of described a plurality of clamping devices.
When adopting technique scheme, it is the distal end of cam that rotating shaft drives the contact-making surface that cam turns to the body that expands, and makes the cam jack-up body that expands, and the body extrusion spring that expands compresses spring, and place work piece is on work stage then.Rotating shaft drives cam and turns to contact-making surface with the body that expands when being the proximal part of cam, recoil of spring, and the body that promotes to expand moves downward, thus the bloated piece that drives the body that expands struts elastic jacket to pressing down, and allows the elastic jacket workpiece pressing, thus realize clamping; Rotating shaft drives cam and turns to contact-making surface with the body that expands when being the distal end of cam again, the cam jack-up body that expands, and the bloated piece on the body that expands pops up, and discharges the extruding to elastic jacket, and elastic jacket discharges the pressure to workpiece, thus workpiece is unclamped in realization; So only just can realize the clamping of workpiece fast with less power rotating shaft and unclamp, time saving and energy saving.And a plurality of above-mentioned same clamping devices are arranged in the matrix, and can clamp a plurality of workpiece simultaneously or a plurality of positions of workpiece are clamped, efficient improves.
Further, there is pin described rotating shaft one end perpendicular to shaft axis and is close to the matrix outer wall and passes rotating shaft; The other end of described rotating shaft is provided with cylindrical handle; Described cylindrical handle is fixed with rotating shaft and contact with the matrix outer wall; Such structure stops rotating shaft laterally to be slided, and the position of stationary cam prevents that cam and bloated body break away from.
Further, described cylindrical handle is provided with a through hole perpendicular to the cylindrical handle axis.Such structure can be so that pass through hole with bar, convenient drive rotating shaft rotation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model multistation clamping device.
The specific embodiment
Embodiment 1: as shown in Figure 1, the utility model provides the multistation clamping device, comprises matrix 1, rotating shaft 3 and clamping device, and described rotating shaft 3 laterally runs through matrix 1 and is positioned at base 2 tops; Described rotating shaft 3 is provided with cam 4; Described cam 4 contacts with clamping device; Described clamping device is positioned at matrix 1, and described clamping device comprises elastic jacket 12, expand body 7 and slip cap 8, and described elastic jacket 12 contacts with bloated body 7; Described bloated body 7 passes slip cap 8; Described bloated body 7 comprises pedestal 9, screw rod 10 and bloated piece 11, and described screw rod 10 1 ends embed in the pedestal 9 fixed with pedestal 9, and other end axially-extending goes out pedestal 9 and bloated piece 11 is fixed; Described bloated piece 11 is positioned at elastic jacket 12 and is used for strutting elastic jacket 12; Described slip cap 8 is hinged with matrix 1; Be provided with spring 14 in the described slip cap 8; One end of described spring 14 is fixed in the slip cap 8, and the other end contacts with bloated body 7; The parallel placement arranged side by side of a plurality of described clamping devices is arranged in the described matrix 1; Described rotating shaft 3 is provided with a plurality of cams 4 and the corresponding contact respectively of described a plurality of clamping devices.
During use, it is the distal end of cam 4 that first rotating shaft 3 drives the contact-making surface that cams 4 turn to bloated body 7, makes the cam 4 jack-up body that expands, and body 7 extrusion springs 14 that expand compress spring 14, and place work piece is on work stage then.Rotating shaft 3 drives cams 4 and turns to contact-making surface with bloated body 7 when being the proximal part of cam 4, spring 14 pressures are removed, spring 14 resiliences, the body 7 that promotes to expand moves downward, thereby drive the bloated piece 11 of the body 7 that expands to pressing down, the piece 11 that expands struts elastic jacket 12, allows elastic jacket 12 workpiece pressings, thereby realizes clamping; Rotating shaft 3 drives cams 4 and turns to contact-making surface with bloated body 7 when being the distal end of cam 4 again, the cam 4 jack-up body 7 that expands, the bloated piece 11 that drives on the body 7 that expands pops up, and discharges the extruding to elastic jacket 12, the pressure that elastic jacket 12 discharges workpiece, thus realize unclamping workpiece.
The difference of the multistation clamping device of 2: the second kinds of embodiments of embodiment and the multistation clamping device of first kind of embodiment only is that there is pin 13 described rotating shaft 3 one ends perpendicular to rotating shaft 3 axis and is close to matrix 1 outer wall and passes rotating shaft 3; The other end of described rotating shaft 3 is provided with cylindrical handle 5; Described cylindrical handle 5 and rotating shaft 3 are fixed and contact with matrix 1 outer wall.Such structure stops rotating shaft 3 laterally to be slided, and the position of stationary cam prevents that cam and bloated body break away from.
Embodiment 3: the difference of the multistation clamping device of the third embodiment and the multistation clamping device of second kind of embodiment only is that described cylindrical handle 5 is provided with a through hole 6 perpendicular to cylindrical handle 5 axis.Such structure can make things convenient for the application of force to drive rotating shaft 3 and rotate so that pass through hole 6 with bar.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
