Abstract
The invention relates to a positioning and clamping device, in particular relates to a power-driven excircle positioning and clamping device and belongs to the technical field of clamps. The positioning and clamping device comprises an upper positioning plate and a lower positioning plate, wherein a power cylinder is fixed on the lower positioning plate; a positioning sleeve is supported on the upper positioning plate; a positioning sleeve inner cavity is formed in the positioning sleeve; a clamping body is arranged in the positioning sleeve inner cavity; the clamping body is a cone frustum; the positioning sleeve inner cavity is a cone cavity which is matched with the clamping body; the lower end of the clamping body is connected with a pull rod; and the pull rod penetrates through the positioning plate to be connected with a push rod of the power cylinder. According to the positioning and clamping device, the precision for positioning the parts is greatly improved; compared with the current V-shaped block manner, the repositioning precision of a rotation center is more than doubled; the stress evenness of the parts is improved, especially for thin-wall parts; and the error caused due to deformation is greatly reduced.
Description
Technical field
The present invention relates to a kind of positioning clamping device, a kind of power drive excircle orientation clamping device, belongs to clamp technology field specifically.
Background technology
At present, during Cutter Body Processing with Machining Center machine components, the part to need with excircle orientation and clamping, is to adopt two relative V-block mechanisms that part outer is positioned and clamped.First analysis from locating, because different part outers is discrepant, adopt V-block mechanism location time, the each location of the centre of gyration of part is all inconsistent, brings adverse effect to postorder precision machining location; From clamping mode, analyze again in addition, current clamping is to rely on to adjust screw by manually one in two V-blocks being moved left and right part outer is clamped, this mode efficiency is low, each not of uniform size causing of power clamping, also can cause part stress different, part is yielding, thereby part processing precision is exerted an influence.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby provide a kind of power drive excircle orientation clamping device, for the processing parts that needs excircle orientation, carry out power drive fast positioning clamping, can effectively improve the repetitive positioning accuracy of the part work in-process that relies on excircle orientation, reduce the distortion of part, shorten location and clamping time.
According to technical scheme provided by the invention, power drive excircle orientation clamping device comprises location-plate and lower location-plate, between upper location-plate and lower location-plate, by two support plates, link into an integrated entity, it is characterized in that: stationary power cylinder on lower location-plate, upper location-plate upper support positioning sleeve, in positioning sleeve, be provided with positioning sleeve inner chamber, in positioning sleeve inner chamber, be provided with clamping body.Described clamping body is the frustum of a cone, and positioning sleeve inner chamber is the conical cavity coordinating with clamping body.Clamping body lower end cylinder lever connecting rod, pull bar is connected with the push rod of power cylinder through upper location-plate.
Further, power cylinder is oil cylinder or cylinder.
Further, in clamping body, be provided with and clamp chamber, along clamping body circumferencial direction, be evenly provided with a plurality of expansion slots; Clamping body upper outer circumference is provided with limiting stand.
Further, positioning sleeve lower end is provided with positioning sleeve support plate.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, rationally, adopt pneumatic or hydraulic power, by clamping body to foreign round class part position and clamp, location clamping time is less than 2 seconds, has reduced labour intensity; The precision of part location improves greatly, the centre of gyration, and the more existing V-block mode of repetitive positioning accuracy is enhanced about more than once; Improve the uniformity of part stress, particularly to thin wall component, greatly reduced the error that modification produces.
Accompanying drawing explanation
Fig. 1 is explosive view of the present invention.
Fig. 2 is that the present invention partly cuts open figure.
Description of reference numerals: 1-clamping body, 1.1-clamp location-plate, 8-positioning sleeve inner chamber, 9-positioning sleeve support plate under chamber, 1.2-expansion slot, 1.3-limiting stand, 2-pull bar, 3-positioning sleeve, the upper location-plate of 4-, 5-power cylinder, 6-support plate, 7-.。
The specific embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention mainly comprises location-plate 4 and lower location-plate 7, between upper location-plate 4 and lower location-plate 7, by two support plates 6, link into an integrated entity, and stationary power cylinder 5 on lower location-plate 7.Described power cylinder 5 is oil cylinder or cylinder.
Upper location-plate 4 upper support positioning sleeves 3, are provided with positioning sleeve inner chamber 8 in positioning sleeve 3, be provided with clamping body 1 in positioning sleeve inner chamber 8.Described clamping body 1 is the frustum of a cone, and positioning sleeve inner chamber 8 is the conical cavity coordinating with clamping body 1.Clamping body 1 lower end cylinder lever connecting rod 2, pull bar 2 is connected with the push rod of power cylinder 5 through upper location-plate 4.
In described clamping body 1, be provided with and clamp chamber 1.1, along clamping body 1 circumferencial direction, be evenly provided with a plurality of expansion slots 1.2.During work, power cylinder 5 pulls clamping body 1 downwards by pull bar 2, and clamping body 1 is shunk by positioning sleeve 3 extruding in positioning sleeve inner chamber 8, thus Quick-clamped cylindrical class part.
Described clamping body 1 upper outer circumference is provided with limiting stand 1.3, relies on limiting stand 1.3 to carry out spacing before clamping body 1 enters in positioning sleeve inner chamber 8 completely.
Described positioning sleeve 3 lower ends are provided with positioning sleeve support plate 9, and positioning sleeve 3 is bearing on upper location-plate 4 by positioning sleeve support plate 9.
Operation principle of the present invention is: the present invention has the part to be processed of cylindrical for clamping location.During work, part to be processed is put into clamping body, starts power cylinder and pulls clamping body downwards by pull bar, and clamping body is shunk by positioning sleeve extruding in positioning sleeve inner chamber, thus Quick-clamped cylindrical class part.Clamping body is provided with expansion slot, stressed after-contraction, thus the part axle center that makes to insert in clamping body is concentric and clamped with the axle center of axle sleeve, now can process part.
