Description
Technical field
The present invention relates to a kind of measurement frock, particularly three-dimensional coordinates measurement side plate series products universal fixture, belong to the manufacturing technology field of mechanical processing industry.
Background technology
Coordinate measuring machine is a kind of new and effective fine measuring instrument, has become the measuring equipment that modern industry detects and production quality control is indispensable.The critical component side plate series products of hydraulic gear pump, in 8 fonts, thickness is thin: 1.5-10mm, slenderness ratio value is large: be generally greater than 10, and the accuracy of form and position particularly the flatness of side plate both ends of the surface and the depth of parallelism require high, the existing pressing plate frock of three coordinate measuring machine and adopt that plasticine is fixing waits some to detect frocks, exists: 1) snap-in force is uncontrollable, cause product clamping deformation, affect the reliability of measurement result; 2) do not have adjustable support limit mechanism, test product Set and Positioning is inaccurate, should not repeat all automatic measurement continuously; For the product changing different size, change clamping tooling, this all affects measuring speed, causes inefficiency.Existing patent ZL 200420029658.7, ZL 200920227810.5 and ZL 201020131055.3 can not be applicable to the detection of side plate series products, once can not complete the flatness of side plate both ends of the surface and the measurement of the depth of parallelism.
Summary of the invention
The present invention seeks to the weak point for avoiding existing for above-mentioned prior art, there is provided one to be provided with and compress adjusting mechanism, locate reliable, clamping three-dimensional coordinates measurement side plate series products universal fixture fast, once can complete the measurement of side plate two faces parallels and flatness, increase work efficiency, reduce measuring error.
The present invention is that technical solution problem adopts following technical scheme:
The design feature of three-dimensional coordinates measurement side plate series products universal fixture of the present invention consists of by guide rail, pillar and cantilever the framework do not closed on one side with being threaded, and is provided with compression adjusting mechanism, guide rail is provided with support limit mechanism at the cantilever end of cantilever.
The design feature of three-dimensional coordinates measurement side plate series products universal fixture of the present invention is also:
Described compression adjusting mechanism is set to: pressure head fixed cover is fixed on the cantilever end of cantilever, and seaming chuck is arranged on depression bar lower end; Depression bar is arranged in pressure head fixed cover; Regulate swing arm with depression bar for being threaded, knob is contained in the upper end regulating swing arm, limiter adjusting knob is limited to the end face of knob by screw, the end face of limiter adjusting knob and knob leaves gap, in limiter adjusting knob, be provided with stepped hole, in described stepped hole, load steel ball, spring and limiter screw successively.
Described support limit organization establishes is: dovetails is arranged in the dovetail groove of guide rail, and dovetails and bearing are screwed, and support is contained in bearing upper end, is provided with limited block at support one side, is provided with latch segment and eccentric rotary axle in the holder.
Guide rail is provided with one or two support limit mechanism.
The surface contacted with test product at seaming chuck and support is provided with aluminium flake or rubber peel.
In the present invention, bearing settlement is on guide rail, unscrews eccentric rotary axle, and bearing at slide on rails, to adapt to the different length of side plate, can tighten eccentric rotary axle, bearing can be fixed on certain position of guide rail; " V " shape groove on support makes different size, can meet the needs of multiple product.
Regulate pressure head fixed cover at the fixed position relative of cantilever in the present invention, the height change of side plate can be adapted to; Adjustment limiter screw can adjust the elastic force of spring, and then adjustment steel ball is to the snap-in force size of knob end face, reaches and controls screwing force at a certain numerical value, avoids that snap-in force is excessive causes deformation of products or surface damage.
Compared with existing technology, the effect that the present invention is useful is embodied in:
The detection that the present invention is not only applicable to side plate series products is also applicable to the detection of the non-side plate series products of part, and such as gear ring, axle sleeve etc., once can complete the measurement of measured workpiece flatness and depth of parallelism equidimension and form and position tolerance; Compress when adjusting mechanism can ensure product clamping and do not deform, the reproducibility and reliability detecting data can be ensured; Support limit mechanism has good positioning function, easy to operate, and different types of product only need change support corresponding to adjustment, can one-time programming for identical product, reuses, is applicable to batch detection, raising detection efficiency.
