The quick clamping device has the characteristics of being reasonable in design, simple and convenient to operate, wide in application scope, low in production cost, easy to operate and quick to clamp work-pieces, so that the quick clamping device can be conveniently popularized and used.

Description

Shaft-like workpiece fast fixture

Technical field

The utility model belongs to Machining Technology field, relates to a kind of clamping device, is specifically related to a kind of shaft-like workpiece fast fixture.

Background technology

At present, clamping device is all widely used in all trades and professions, helical clamping apparatus is current modal clamping device, the direct clamping work pieces of its general using screw thread, or form compound clamp mechanism with other elements or mechanism, there is the advantages such as reliable clamping in helical clamping apparatus, but helical clamping apparatus equally also exists and clamps the shortcomings such as slow motion, clamping efficiency are low.Particularly, when using helical clamping apparatus frequently alternately to clamp the workpiece varying in size, need the frequent rotating screw bolt of operating personnel with clamping work pieces, greatly increased operating personnel's labour intensity, reduced production efficiency.

Utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of shaft-like workpiece fast fixture is provided, and it is reasonable in design, and clamping work pieces is quick, rapid, simple to operation, simple in structure, rapid operation, applied widely, production cost is low, is convenient to promote the use of.

For achieving the above object, the technical solution adopted in the utility model is: a kind of shaft-like workpiece fast fixture, comprise the base playing fixed supporting role, it is characterized in that: described base left end upside is fixedly installed V-type buting iron, described base middle part upside is fixedly installed pusher bar support, described base right-hand member upside is fixedly installed drag link bearing, on described pusher bar support, be slidably fitted with L-type push rod, described L-type push rod one end is provided with the V-type pressure head for coordinate workpiece pressing with described V-type buting iron, the described L-type push rod other end is slidably mounted on the chute that is positioned at pull bar middle part by rolling bearing, described pull bar lower end and described drag link bearing are rotationally connected, between described V-type pressure head and described pusher bar support, be provided with the holddown spring for apply thrust to described V-type pressure head.

Above-mentioned shaft-like workpiece fast fixture, is characterized in that: described pull bar is connected by rotating shaft with described drag link bearing.

Above-mentioned shaft-like workpiece fast fixture, is characterized in that: described V-type buting iron, described pusher bar support and described drag link bearing all weld or be arranged on described base by bolt.

The utility model compared with prior art has the following advantages:

(1) this shaft-like workpiece fast fixture design is very reasonable, and operating personnel only need pull pull bar and workpiece is put into appropriate location, and releasing lever gets final product clamping work pieces, thereby its clamping work pieces is quick, rapid, operates very simple and convenient.

(2) this shaft-like workpiece fast fixture is simple in structure, and leverage makes its operation very laborsaving.

(3) this shaft-like workpiece fast fixture is not only applicable to shaft-like workpiece Machining Technology field, is applicable to non-shaft-like workpiece Machining Technology field yet, be also applicable to the place that other needs Quick-clamped, thereby its scope of application is very extensive.

(4) requirement on machining accuracy of this shaft-like workpiece fast fixture is low, and a lot of parts are all convenient to produce very much, purchase, thereby its production cost is very low, is convenient to promote the use of.

Below by drawings and Examples, the utility model is described in further detail.

The specific embodiment

A kind of shaft-like workpiece fast fixture as depicted in figs. 1 and 2, comprise the base 1 playing fixed supporting role, described base 1 left end upside is welded with V-type buting iron 2, described base 1 middle part upside is welded with pusher bar support 6, described base 1 right-hand member upside is welded with drag link bearing 10, on described pusher bar support 6, be slidably fitted with L-type push rod 7, described L-type push rod 7 one end are provided with the V-type pressure head 4 for coordinate workpiece pressing 3 with described V-type buting iron 2, described L-type push rod 7 other ends are slidably mounted on the chute 8-1 that is positioned at pull bar 8 middle parts by rolling bearing 9, described pull bar 8 lower ends and described drag link bearing 10 are rotationally connected, described pull bar 8 is connected by rotating shaft with described drag link bearing 10.Between described V-type pressure head 4 and described pusher bar support 6, be provided with the holddown spring 5 for apply thrust to described V-type pressure head 4.

The course of work of the utility model shaft-like workpiece fast fixture is: first this shaft-like workpiece fast fixture is fixedly mounted on platen, operating personnel pull pull bar 8, pull bar 8 clockwise rotates and drives L-type push rod 7 to slide backward around drag link bearing 10, L-type push rod 7 drives V-type pressure head 4 to move backward, now operating personnel put into workpiece 3 groove of V-type buting iron 2, releasing lever 8, V-type pressure head 4 can be under the effect of holddown spring 5 workpiece pressing 3.When workpiece 3 is processed complete after, operating personnel pull pull bar 8, the workpiece processing 3 can be taken out, it is very convenient to operate.

The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification, change and equivalent structure transformation of above embodiment being done according to the utility model technical spirit, all still belongs in the protection domain of technical solutions of the utility model.
