Abstract
The invention discloses a chuck device. The chuck device comprises a body, transmitting steel balls, an inner cam rotating sleeve, a spring, a pressing plate, a mandrel and a double-V chuck body, wherein the mandrel, the transmitting steel balls and the spring are positioned in the body; the pressing plate is fixedly connected with the body; the radius of the inner cam rotating sleeve becomes small to generate radial force on the steel balls to overcome the elastic force of the spring and to act on the mandrel to realize the radial opening of the double-V chuck body; the radius of the inner cam rotating sleeve becomes big, and the chuck is closed for clamping by utilizing the elastic recovery of the spring and the double-V chuck body. The chuck device can quickly and accurately clamp a flexible rod, clamping coaxiality control can be guaranteed through one-time assembly, high repeatability and stability are achieved, a busbar retaining mode can be matched with detection equipment for use to perform busbar track tests and the like on parts, and the adjustment efficiency is obviously improved.
Description
Technical field
The present invention relates to clamp fixture technical field, and in particular to a kind of high accuracy circular column axis positioning collet device.
Background technology
In the dynamic tuning gyroscope platform that certain delivery model is used, flexibility bar diameter of part is only 0.8mm or so, belongs to key component,
Accurate measurement is carried out to which, flexibility bar directly affects the repeated measure error of flexibility bar with center of collet dead in line precision,
Set and Positioning and repeatable accuracy is asked to be less than 0.0005mm.Therefore, how reliable and stable on the premise of high duplication is ensured dress
Folder flexibility bar, it is ensured that product overall performance is most important.
During flexibility bar rigidity precision measuring instrument is developed, positioning and repetition are debug precision and are difficult to meet
The requirement of 0.0005mm, causes flexibility bar rigidity precision measuring instrument to can not meet the micro- rigidity test requirement to flexibility bar, scratches
Center superposition degree accurately cannot ensure both during property bar clamping, and clamping method is very high to operator's skill set requirements.Which is basic
Principle is that flexibility bar is put into precision spring chuck, is headed into flexibility bar embedded part with a screw through installing hole.
Tighten flexibility bar during collet easily to come off or cause part injury, and it is fixed after with central axes precision compared with
, easily there is " sticking up tail " phenomenon, also can not meet the unscreened requirement of two side bus in difference.This debugs flow process complexity, and efficiency is low.
Therefore, industry needs a kind of symmetrical bus that can meet whole part unobstructed and while the high precision of axis location
Device, improve precision screening measurement process in operate.
The content of the invention
The present invention is intended to provide a kind of cartridge device, can fast and accurately clamping flexibility bar, can be by once assembling
Ensure the control of clamping axiality, efficiency is debug in raising.
In order to reach it is above-mentioned witness, the present invention proposes a kind of cartridge device, including：Body, transmission steel ball, convex rotation
Set, spring, pressing plate, mandrel, double V-shaped collet body；The mandrel, transmission steel ball and spring are located within body, the pressing plate and
Body is fixedly connected, and the cam ring pivoted housing radius diminishes and the elastic force of spring is overcome to the radial force that steel ball is produced, and acts on
Realize radially expanding for double V-shaped collet body on mandrel, the radius of cam ring pivoted housing becomes big, using spring and double V-shaped collet body
Elastic return realizes that closure is clamped.
In some embodiments, the double V-shaped collet body radially expands parallelogram structure, it is ensured that chucking power is equal
Weighing apparatus.
In some embodiments, the double V-shaped collet body is fastened with body by three screws.
In some embodiments, the double V-shaped collet body is made up of highly elastic material.
In some embodiments, the double V-shaped collet body is in symmetric clamp, symmetrical double V-shaped collet body elastic restoring force
Interact with cam ring pivoted housing and spring compression force and produce stabilization clamp holding force, it is ensured that repetitive positioning accuracy.
The present invention due to adopting such scheme, can fast and accurately clamping flexibility bar, can guarantee by once assembling
Clamping axiality is controlled, and possesses high duplication, stability, and bus hold mode can arrange in pairs or groups testing equipment using the mother for carrying out part
The work such as line tracking test, significantly improve and debug efficiency.
Description of the drawings
A kind of cartridge device of the present invention is described in detail with reference to the following drawings by reading；Fig. 1 is present invention tool
The unobstructed double V-shaped drawback collet device schematic diagram of bus of body embodiment.
Specific embodiment
Referring to the accompanying drawing for illustrating the embodiment of the present invention, the present invention is described in more detail.However, the present invention can be with
Many multi-forms realize, and should not be construed as and limited by the embodiment for herein proposing.
As shown in figure 1, being the double V-shaped drawback collet device schematic diagram of the unobstructed high duplication of bus of the present invention.The dress
Put including：Body 1, transmission steel ball 2, cam ring pivoted housing 3, spring 4, pressing plate 5, mandrel 6, double V-shaped collet body 7, the mandrel 6,
Transmission steel ball 2 is located within body with spring 4, and double V-shaped collet body 5 is fastened with body 1 by three screws 7, cam ring pivoted housing 3
The extruding force to steel ball 2 is produced by the difference of radius after rotation opening for double V-shaped chuck 7 is realized on mandrel 6 with 4 collective effect of spring
Open, after micro- diameter part is loaded, rotation pivoted housing to initial position, due to spring restoring force and the recovery elasticity of double V-shaped chuck 7
Power, makes bare terminal end close so as to Clamp blocks.Double V-shaped chuck 7 is made up of highly elastic material, and its parallelogram sturcutre ensures folder
Hold side to move in parallel in the range of certain displacement, make chucking power balanced.Also, the thin design of chuck can make micro- diameter part exist
After completing clamping, two side bus are unobstructed, use with testing equipment collocation, facilitate the test of bus track.Meet flexibility bar firm
The measurement clamping of degree fine measuring instrument is required.
The present invention has the advantage that：A kind of cartridge device is provided, can fast and accurately clamping flexibility bar, one can be passed through
Secondary assembling can ensure the control of clamping axiality, and possess high duplication, stability, and bus hold mode testing equipment of can arranging in pairs or groups makes
With the work such as the bus track testing of part are carried out, significantly improve and debug efficiency..
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of spirit or essential attributes without departing substantially from the present invention, the present invention can be realized in other specific forms.
