Description
Technical field
This utility model technology relates to the Machining Technology field, is specifically related to the thick cogging fixture of a kind of herringbone bear.
Background technology
The processing of forcing press herringbone bear is to carry out thick cogging at planer, then carries out adjustable cast iron planes.In the process of thick cogging, herringbone bear needs to fix by fixture and planing machine platen.The structure of fixture as shown in Figure 1, comprise fixed block 1, mandrel 2, pressing plate 3, herringbone bear installation sleeve 12, fixed block 1 is locked by set bolt 4 and planing machine platen 11, at the corresponding surface welding mandrel 2 of fixed block 1 with planing machine platen 11 stationary planes, herringbone bear 5 is installed on the mandrel 2, adopts pressing plate 3 and pressing plate set bolt 4 that herringbone bear 5 is fixedly connected with mandrel 2.Because fixed block 1 adopts the right-angled trapezium cube, herringbone bear 5 forms certain angle with the X-axis of planer, and the teeth groove on the herringbone bear and the X-axis of planer are on same axis, thereby planing tool digs teeth groove in the X-direction motion at herringbone bear.But there is following limitation in this fixture in process: namely the operator is when the processing herringbone bear, whenever process a teeth groove, when reprocessing next teeth groove, herringbone bear all must rotate to Working position around mandrel, because the weight of herringbone bear is very big, the people is very large for pulling its revolving force of herringbone bear, has not only increased labour intensity, and has reduced working (machining) efficiency.
Summary of the invention
For overcoming present herringbone bear in thick cogging process, large, the technical problem that affect working (machining) efficiency of existing labour intensity when conversion herringbone bear Working position, the utility model provides a kind of thick cogging fixture of herringbone bear light, that can significantly improve working (machining) efficiency that operates.
The technical solution adopted in the utility model is: the thick cogging fixture of herringbone bear, comprise fixed block, mandrel, the herringbone bear pressing plate, fixed block is provided with the bolt hole fixing with planing machine platen, the outer end of mandrel is provided with the pressing plate fixed bolt hole, when herringbone bear is installed on the mandrel, pressing plate is pushed down herringbone bear and by set bolt pressing plate and mandrel end is fixed, it is characterized in that: the middle part of described fixed block is provided with the mandrel through hole, the mandrel through hole runs through the contact-making surface of fixed block and planing machine platen and the contact-making surface of fixed block and herringbone bear, be provided with bearing erecting bed and bearing cover erecting bed in the mandrel through hole, bearing is installed in the mandrel through hole and by the bearing cover shutoff, mandrel is positioned at the mandrel through hole and is supported by bearing.
Described fixed block is the right-angled trapezium cube.
For solving when processing the herringbone bear of disalignment bore dia, the difference of its shaft hole diameter and axle diameter, described fixture also comprises the herringbone bear installation sleeve that is installed on the mandrel, the external diameter of described installation sleeve is consistent with the shaft hole diameter of herringbone bear, the internal diameter of installation sleeve is consistent with axle diameter, and the width of installation sleeve is consistent with the herringbone gear shaft hole length.
Described bearing is deep groove ball bearing.
The beneficial effects of the utility model are: by at the fixed block inner fixed bearing, herringbone bear and mandrel can freely rotate in the mandrel through hole, after processing a teeth groove, when the rotation herringbone bear arrived next Working position, because the existence of bearing, its rotatory force alleviated greatly, operating personnel one people can finish, namely alleviated labour intensity, also improved the position and regulated the speed, working (machining) efficiency is greatly improved.This fixture structure is scientific and reasonable, and is easy and simple to handle, can be widely used in the process operation of herringbone bear.
Description of drawings
Accompanying drawing 1 is the structure cutaway view of the fixture of prior art.
Accompanying drawing 2 is structure cutaway view of the present utility model.
Among the figure, 1, fixed block, 2, mandrel, 3, pressing plate, 4, set bolt, 5, herringbone bear, 6, the mandrel through hole, 7, the bearing erecting bed, 8, the bearing cover erecting bed, 9, bearing, 10, bearing cover, 11, planing machine platen, 12, installation sleeve, 13, T-shaped bolt.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 2, the thick cogging fixture of herringbone bear comprises fixed block 1, mandrel 2, herringbone bear pressing plate 3.
As shown in Figure 2, fixed block 1 is the right-angled trapezium cube, inclined-plane and planing machine platen 11 at fixed block 1 are fixed by T-shaped bolt 13, fixed form is that the tail end of T-shaped bolt 13 is arranged in the T-shaped groove on planing machine platen 11 table tops, and the bolt hole that T-shaped bolt 13 passes on the fixed block adopts nut lock to fasten.
As shown in Figure 2, the middle part of fixed block 1 is provided with mandrel through hole 6, mandrel through hole 6 runs through the contact-making surface of fixed block and planing machine platen and the contact-making surface of fixed block and herringbone bear, be provided with bearing erecting bed 7 and bearing cover erecting bed 8 in the mandrel through hole 6, bearing 9 is installed in the mandrel through hole and by bearing cover 10 shutoff, mandrel 2 is positioned at mandrel through hole 6 and is supported by bearing 9.
