Description
Technical field
The invention belongs to synchronizer production technical fields, specifically, in particular to a kind of synchronizer gear sleeve internal tooth M value inspection
Tool.
Background technique
Since transmission input shaft and output shaft are rotated with respective speed, there are one " synchronizations " to ask for conjunction when converting gear
Topic.Two different gears of rotation speed engage by force will necessarily occur impact, damage gear.Therefore, old-fashioned speed changer
Gear shift to upshift and be stopped a moment in neutral position by the way of " bipod clutch ", downshift will in neutral position open out, with
Reduce the rotational speed difference of gear.But this operation is more complicated, it is difficult to grasp accurate.Therefore designer creates " synchronizer ", leads to
Crossing synchronizer makes that meshed gears will be wanted to reach consistent revolving speed and smoothly engage.
The component of reverse gear synchronizer includes tooth set, and annularly, tooth is on inner wall.It can pacify inside tooth set when specifically used
Toothing hub assembles integral use.In order to guarantee that the tooth set produced meets the requirements, need to cover tooth tooth on inner wall into
The detection of row M value, existing M value detection method are using hand-held cubing, and artificial detection is cumbersome, inefficiency.
M value is distance over bar for external gear.To internal gear, stick spacing is.It is also applied for external splines and internal spline.M value
It is control transverse tooth thickness as the effect of common normal.For even number tooth, pole is located at gear tooth slot farthest, pole line of centres
Cross gear centre.For odd number gear, pole is located at gear tooth slot farthest, pole line of centres only gear centre.
Distance over bar is an indirect parameter for indicating transverse tooth thickness, is stuck in opposite tooth socket, is measured outside it with two small poles
The size of edge, here it is distance over bar M, this small pole is known as pitch circle rod.Pay attention to pitch circle rod will with it is tangent at flank of tooth pitch circle.Rack gear
Distance over bar can with a pitch circle rod.
Distance over bar M value is to reflect a measurement index of gear compound graduation knuckle-tooth thickness.It is practical in production because measurement accuracy is higher
Middle application is wider.Pins diameter is standard straight (is similar to standard gauge block), when measurement, by suitably placing it in tooth across the number of teeth
In slot, the distance between two length bars, as distance over bar M are then measured.
Summary of the invention
In view of the above drawbacks of the prior art, technical problem to be solved by the invention is to provide a kind of synchronizer gear sleeves
Internal tooth M value cubing.
Technical solution of the present invention is as follows: a kind of synchronizer gear sleeve internal tooth M value cubing, including bottom plate, the upper table of the bottom plate
The movable measuring head base that has fixed measuring head base and can be moved forward and backward, the fixed measuring head base and movable measuring head base is arranged side by side afterwards in front
On be each provided with a spherical gauge head, two gauge heads settings point-blank, and the fixed measuring head base and activity
The gauge head on measuring head base is respectively directed to front and back；Being provided on the bottom plate can be by the movable measuring head base to pusher
Spring out, the activity measuring head base is connected to can be in the detection block of fore-aft travel, and the detection block is located at the movable gauge head

Using above technical scheme, fixed measuring head base and movable measuring head base cooperate, fixed measuring head base and movable gauge head
Seat is substantially two claws for constituting internal caliber gauge, and passes through the position of centimeter check detection block, indirectly two surveys of measurement
The distance between head.Definition based on the measurement of M value, it is therefore necessary to select spherical gauge head.Due to, needing to live in actual use
Dynamic measuring head base is moved along front-rear direction, needs to reset backward after forward movement, therefore is realized and resetted by setting spring
Movement.Detection block and movable measuring head base are rigidly connected, and detection block is directly touched with the gauge head of dial gauge and realizes detection when detecting,
Detect that tooth covers internal tooth M value indirectly.
Further, mobile towards the direction far from fixed test block under the resilient force of spring due to movable jaw, be
Facilitate and tooth set to be measured is installed on the claw formed by fixed measuring head base and movable measuring head base, needs stationary jaw and work
It reduces between dynamic claw, is realized by the scheme for pushing detection block to retract；Therefore it is provided with control handle on the bottom plate, the control
Handle processed is made of eccentric wheel and handle, and eccentric wheel is rotatably arranged on the bottom plate, and eccentric wheel is for pushing the inspection
Survey the compression that block is mobile, with formation to the spring；The handle is fixed on the eccentric wheel.
Further, for the ease of holding workpiece when in use, it is made to laterally retain smooth, stable state, to guarantee
The accuracy of measurement is provided with tray for work pieces on the bottom plate, a strip-shaped hole is provided in the middle part of the tray for work pieces, described solid
Determine measuring head base and movable measuring head base passes through the strip-shaped hole from the bottom up.
Further, in order to improve the comfort level of measurement by the way that dial gauge is steadily arranged, the dial gauge passes through peace
Dress seat is mounted on the bottom plate.
Further, described in order to which the setting for fixing measuring head base and movable measuring head base is convenient easy to use with entire cubing
The upper surface of bottom plate is provided with the setting slot of bar shaped along the longitudinal direction；The fixed measuring head base is fixedly installed in the setting slot；Institute
Movable measuring head base is stated to be slidably fitted in the setting slot.
Further, in order to facilitate the setting of spring, measuring head base is opposite is respectively provided on one side for the fixed measuring head base and activity
There are spring groove, and position face, the spring is installed in the spring groove.
Further, for the structure feature of combining movement measuring head base, so that movable measuring head base and detection block easily connect,
The lower part of the activity measuring head base is bent backward, and is fixedly connected in the end of bending with the detection block.
The utility model has the advantages that present inventive concept is novel, design is reasonable and easy to use, pass through fixed measuring head base and movable measuring head base
The clamping jaw structure of formation is indirectly measured come the M value for covering internal tooth to tooth, and compared with the existing technology, operation is simpler, whole
Body is more efficient.
