Description
Technical field
The present invention relates to machine tools technical fields, more particularly to a kind of broaching fixture for end-tooth workpiece
And its handling method and horizontal broaching machine.
Background technique
In car transmissions, joining part constantly subjects the impact of shearing and stretching, once failure, will cause to pacify
Full accident.The connection design scheme of domestic heavy goods vehicles transmission system is generally flange arrangement, and end face seam allowance cooperates, bolted on connection,
Transmission system leans on friction and the bolt of both ends of the surface to transmit torque at work, and bolt carrying torque is big during the work time,
Under the impact for being constantly sheared and stretching, Yi Yinqi bolt shears phenomenon, causes to fail.To guarantee the enough intensity of bolt,
In design, increase the volume of part as much as possible, increases bolt quantity, to bring the increase of various economic costs, safety wind
Danger is big, meanwhile, end face seam allowance cooperates required precision high, and flange threaded hole position requires high.
To solve the above-mentioned problems, occurred end-tooth part, i.e. the connection end face of part in transmission system at present
It is equipped with two groups of tooth sockets being distributed at an angle.This solves running failure is driven, transmission performance is improved
And product quality, increase security performance.Meanwhile two groups of tooth sockets being distributed at an angle can guarantee part in operation
It is self-centering, it is ensured that the transmission of torque is steady.
At home, end-tooth part is gradually applied, and milling is usually used in the end-tooth of processing end-tooth part
Cut processing or wire pulling method.Currently, the means that two groups of end-tooths of processing end-tooth part use are: positioning clamps primary first
Workpiece processes one group of end-tooth；Workpiece is removed again, and rotating by a certain angle positioning and clamps workpiece, processes another group of end face
Tooth.1) this manufacturing process has the following deficiencies: since using the processing end-tooth of clamping twice, position error is accumulative big, workpiece
Unstable quality, be easy to appear waste product；2) since processing end-tooth needs clamping twice, thus the non-cutting time of separate room processing
Longer, production efficiency is low.
In addition, the type of cooling of traditional horizontal broaching machine is directly to spray to coolant liquid outside the top of workpieces processing by outside
Side, the characteristic then to flow downward by coolant liquid gradually flow to workpiece bottom end, and this mode is can to play certain cooling
Effect, but effect is not significant.Because the mating surface of workpiece and broaching tool is in horizontal direction substantially, coolant liquid flow to the mating surface
When only a fraction can act on the machined surface of broaching tool and workpiece, but there is more part coolant liquid not play Essential Action.
Summary of the invention
To overcome technological deficiency of the existing technology, the present invention provides a kind of broaching fixture of end-tooth workpiece, once
Clamping improves production efficiency, and can avoid damage of the pressing device to workpiece, processing quality good stability.

It is stretched on the crossbeam answered and under opposite crossbeam.
Preferably, the rotary barrel is same by rotating cylinder, with respect to the angle scale of rotating cylinder top diameter convex and by bolt
The composition of the axial limiting block on angle scale is arranged in axis, is equipped with rolling bearing and plane axis between the rotating cylinder and mounting rack
It holds, the axial limiting block matches face with operation disk equipped with annular card convex, and the operation disk is equipped with and annular
The annular groove that card convex matches.
Preferably, circumferentially spaced positioning spline there are two being set on the angle scale, the angle control mechanism packet
Include the hand driving lever being connected with angle scale and with the positioning spline rotatable engagement for keeping rotary barrel to rotate angle
Positioning cylinder.
Preferably, the tension shaft outer wall is symmetrically arranged with two keys, the rotary barrel with the radial corresponding inner circumferential of key
Axial keyway is equipped at the position of face, the key on tension shaft slides up and down the axial keyway being matched on rotary barrel and makes described
Tension shaft and rotary barrel rotate synchronously.
Preferably, chamber resettling and tensioner component, the top opening and tool of the chamber resettling are equipped in the tension shaft
There is internal screw thread, there are two radial through-hole, chamber resettling inside middle section is equipped with platform for the bottom symmetrical setting of the chamber resettling
Terrace；The tensioner component includes that thrust axis, motion bar, link block, reset spring and two are movably connected in work by pin
The tightening piece of lever bottom, the motion bar are plugged in chamber resettling and are bolted to connection the connection on its top
Block, for the reseting spring sleeve outside motion bar and between link block and step surface, the thrust axis is threaded in accommodating
It is abutted against at the top of chamber interior top and its bottom end and link block, each tightening piece is with the pushing or rising of motion bar and through phase
The radial through-hole answered is overhanging or inside contracts.
Preferably, the bottom end of the chamber resettling is also connected with adjusting screw, and the adjusting screw is vertically arranged and it is pushed up
End offsets with tightening piece.
The present invention furthermore provides a kind of horizontal broaching machine, including rack, broaching tool, tool apron, positioning disk and above-mentioned end face
The broaching fixture of tooth workpiece, the tool apron are concavely provided with broaching tool sliding slot, and the positioning disk is installed on tool apron and is located at broaching tool and slides
Above slot and below clamp sleeve, the broaching tool move along a straight line along broaching tool sliding slot and to compress setting clamp sleeve and tool apron it
Between workpiece bottom carry out broaching operation.
Preferably, it is respectively equipped at least one set of cooling duct in the tool apron of broaching tool trough width direction two sides, it is each cold
But the liquid outlet in channel is opposite with workpiece bottom；The horizontal broaching machine further includes cooling system, and the cooling system includes cooling tube

Face.
The present invention furthermore provides a kind of handling method of broaching fixture for end-tooth workpiece, specifically includes as follows
Step:
Promoting lifting support makes Workpiece clamping device and Workpiece rotating device rise to preset height with lifting support, adjusts
Then workpiece is covered outside tension shaft bottom and makes tightening piece overhanging and support workpiece by the first angle of whole good rotary barrel,
Then rotation operation disk ramps tension shaft and workpiece to clamp sleeve bottom end closely to offset；
Reducing lifting support makes workpiece be folded in the end-tooth drawing for carrying out first angle between clamp sleeve and tool apron
It cuts；
After the completion of the end-tooth broaching of first angle, rises lifting support, adjust the second angle of rotary barrel and make
Workpiece synchronous rotary；
Reducing lifting support makes workpiece be folded in the end face for carrying out second angle between clamp sleeve and tool apron again
Tooth broaching, this process do not need to unload workpiece；
Second angle end-tooth broaching after the completion of, rise lifting support, backwards rotation operation disk make tension shaft and
The decline of workpiece straight line is detached from clamp sleeve, and then contrary operation inside contracts tightening piece with workpiece mutually from so that two will be processed
The workpiece of group end-tooth is removed.
Beneficial effects of the present invention:
Since workpiece pressuring clamping device includes clamp sleeve, tension shaft and the operation disk being threadedly engaged with tension shaft, tensioner
