For achieving the above object, the technical solution used in the present invention is: the manual self-locking compressing fixture of a kind of columnar workpiece, comprise base plate, to be fixedly installed on the upside of described base plate for the V-shaped groove cushion block one of support drum workpiece and V-shaped groove cushion block two, it is characterized in that: also comprise the thread bush one that cooperatively interacts and form screw thread pair and screw rod one, the cooperatively interact thread bush two that forms screw thread pair and screw rod two, for installing the portal trestle one of described thread bush one and the portal trestle two for installing described thread bush two; Described portal trestle one and described portal trestle two is symmetrically arranged with on the upside of described base plate, described portal trestle one is fixedly installed thread bush one, screw rod one is provided with in described thread bush one, described screw rod one lower end is rotatablely equipped with the V-shaped groove pressure head one for compressing described columnar workpiece, described portal trestle two is fixedly installed thread bush two, be provided with screw rod two in described thread bush two, described screw rod two lower end is rotatablely equipped with the V-shaped groove pressure head two for compressing described columnar workpiece.
The manual self-locking compressing fixture of above-mentioned columnar workpiece, is characterized in that: described V-shaped groove pressure head one is hinged on described screw rod one lower end, and described V-shaped groove pressure head two is hinged on described screw rod two lower end.
The manual self-locking compressing fixture of above-mentioned columnar workpiece, is characterized in that: described V-shaped groove cushion block one and described V-shaped groove cushion block two are all welded or be fixedly mounted on the upside of described base plate by screw.
The present invention compared with prior art has the following advantages:
(1) design of this columnar workpiece manual self-locking compressing fixture is very reasonable, and compress columnar workpiece by screw thread pair, thus its reliable clamping, reinforcement is large, and self-locking property is good.
(2) structure of the manual self-locking compressing fixture of this columnar workpiece is very simple, and operating personnel only need rotary motion handle can clamp or unclamp columnar workpiece, operate very easy.
(3) in use there is not rigid shock in the manual self-locking compressing fixture of this columnar workpiece, and thus its service life is very long.
(4) the manual self-locking compressing fixture of this columnar workpiece is not only applicable to Machining Technology field, and be also applicable to the place that other needs to clamp columnar object, thus its scope of application widely.
(5) requirement on machining accuracy of this columnar workpiece manual self-locking compressing fixture is low, and a lot of parts are convenient to produce, buy all very much, and thus its production cost is very low, is convenient to promote the use of
Below by drawings and Examples, the present invention is described in further detail.
