Description

A kind of symmetry cubing
Technical field
The utility model relates to gear cubing field, especially relates to a kind of symmetry cubing.
Background technology
In the auto parts and components process, reverse idler gear processing key operation---detect invert shape angle, detection mode mainly adopts universal tool-measuring microscope or expensive detection equipment to add expensive detection software and realizes, adopt the accuracy of detection of universal tool-measuring microscope can not satisfy existing design accuracy requirement far away, and expensive detection equipment is when detecting multiple tooth data product, detection efficiency is very low, and, can not adapt to production in enormous quantities and detect needs efficiently, accurately environment for use, harshness that the place requires.In sum, the detection mode of symmetry can not satisfy actual needs well in the prior art, and its accuracy of detection is low, detect the cost height, detection efficiency is low, it is big to detect error, has increased processing cost.
Summary of the invention
The purpose of this utility model is to provide a kind of easy to detect and symmetry cubing that can accurate reading.
The technical solution of the utility model is:
A kind of symmetry cubing comprises base plate, is connected with guide rail on the described base plate, guide rail one slide that has been dynamically connected that breaks away, and described slide one side is connected with ejector pin mechanism, and the slide opposite side is connected with positioning core axle; The opposite side of described base vertically is connected with riser, is connected with two tong-test ammeter framves on the side side of described riser, and two tong-test ammeter framves have clamped a dial gauge about the center line symmetry of guide rail on each tong-test ammeter frame; Described positioning core axle is between ejector pin mechanism and tong-test ammeter frame; The downside of described riser is connected with the dog screw bar.
Described positioning core axle is provided with step, is placed with cushion cover on the described step.
Described dog screw bar and riser be for being threaded, the setting nut that has been threaded on the described dog screw bar, and setting nut is positioned at dog screw bar and riser junction.
The bearing of trend of described dog screw bar and guideway centreline's line parallel.
The utility model adopts high-precision fixed guide, fixedly slide block solves the accuracy problem that measurement is advanced and retreat back and forth, and its flexible operation is quick, the repeatability precision height.Guideway centreline and riser center are controlled on the center line, and two measure tong-test ammeter frame endoporus to tong-test ammeter frame bottom size tolerance control unanimity, guarantee measuring accuracy.The center that tong-test ammeter frame angle is installed is consistent with guide rail center line center on base plate, and the angle angle [alpha] conforms to product cydariform angle between two dial gauges of laying, and the angle of tong-test ammeter frame generally obtains with angular templet on the riser.Spacing dog screw bar scalable is spacing, is installed in riser below proper site, effectively control gear drum planar survey spot size position.Tip mechanism can satisfy the requirement of the adjusting of test product location, angle.Tip mechanism is fixed on the rational position of slide.The spring of rolling center detent mechanism is scalable to be made things convenient for product to take into to take out, and can effectively regulate the skew of the angle position, measurement dial gauge center of tong-test ammeter frame on the center of tested cydariform face gear teeth and the riser.The utility model is easy to detect, and is accurately quick.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that K among Fig. 1 is to view.
Embodiment
As shown in Figure 1, the utility model comprises base plate 1, and base plate 1 upside is connected with guide rail 2, slidely connects slide 3 on the guide rail 2.Slide 3 left sides are connected with positioning core axle 10, positioning core axle 10 is provided with axle, and the hole of gear to be detected is put into and can be realized in the axle fixing, and positioning core axle 10 is provided with step surface, be placed with cushion cover 15 on the step surface, the height of cushion cover 15 should be set according to the thickness of gear 14 to be measured; Slide 3 right sides are connected with tip mechanism, and tip mechanism comprises that the location clamps upright cover 11 and rolling center 13, and the location clamps in the upright cover 11 and slidely connects rolling center 13, and rolling center 13 right-hand members connect location handle 12.Be arranged with back-moving spring on the rolling center 13 right-hand part split axles, pulling location handle 12 to the right, and back-moving spring is compressed, unclamp location handle 12 after, rolling center 13 is got back to original position.
The left end of base plate 1 is connected with riser 4, and riser 4 vertically is provided with.The right flank of riser 4 upsides is connected with two tong-test ammeter framves 8 by bolt, and as shown in Figure 2, two tong-test ammeter frame 8 left-right symmetric tilt to install, and have clamped dial gauge 9 on the tong-test ammeter frame 8.The center of the center of guide rail 2 and riser 4 should be controlled on the same center line.
The center of tong-test ammeter frame 8 angles should be consistent with the center line of guide rail 2, and the cydariform angle of angle angle [alpha] and gear 14 to be measured conforms between two dial gauges 9.
The downside of riser 4 laterally is provided with screw 7, and dog screw bar 5 screws in the screw 7, and dog screw bar 5 is provided with setting nut 6 with riser 4 junctions, is the length that scalable dog screw bar 5 exposes riser 4 by screwing setting nut 6.Dog screw bar 5 exposes the length of riser 4 should be according to the distance setting of the gear 14 top and to be measured of dial gauge 9.When slide 3 slid into high order end, dog screw bar 5 ends and slide 3 were abutted against and are spacing.
According to the difference of product endoporus to be measured, high low dimensional, replaceable corresponding positioning core axle 10 and cushion cover 15.If want the gear cydariform angle difference of testing product, available angular templet requires to regulate the angle of two tong-test ammeter framves 8 on the riser 4 according to angle.
Job step: at first master body is placed in 10 li of positioning core axles, the location of right hand pulling simultaneously handle 12, the back-moving spring compression that rolling center is 13 li, master body is put into, rolling center 13 is facing to the loosening right hand between master body gear two teeth, and the top ball of rolling center 13 utilizes the power of back-moving spring the automatic positioning and fixing of master body.Promote location handle 12 slide 3 is advanced along the gathering sill of guide rail 2, during the in-position, dog screw bar 5 is spacing, uses the fix stopper gear.The tooth cydariform face of tested master body just in time between two dial gauges 9, begins to show reading, and dial gauge 9 readings are located at " 0 " position, and with this as detecting foundation.After having surveyed, take off the fix stopper gear, retract slide 3, take out master body.
During detection, pulling location handle 12 is put into gear 14 to be measured, loosens location handle 12, and the ball of rolling center 13 is automatically gear 14 positioning and fixing to be measured.Promote mechanism's feeding on the guide rail 2, stop screw bar 5 is spacing, and observation dial gauge 9 shows readings, and according to the reading size of measuring dial gauge, whether the center of judging tooth is offset and what size is offset.Retract slide 3 then, pulling location handle 12, the angle of a tooth of transmitting gear is loosened location handle 12 then, promotes slide 3 to the detection position, detects another tooth, and repetitive operation can detect the center of whole teeth successively.
