Abstract
The utility model relates to a gear box supports positioner, including the gyro wheel dolly, be fixed with central nut on the gyro wheel dolly, the dish that shakes that has the crank is connected through flat housing in the last plane of central nut, shakes dish and central nut and has all offered screw, lead screw screw in shake the screw of dish and central nut, the top of lead screw is connected with the supporting platform who is used for supporting the gear box. The utility model discloses the gear box supports steadily in the time of can guaranteeing effectively that axletree processing is rotatory, and the inside gear of gear box operates steadily, has reduced because the gear box rocks the axletree diameter runout phenomenon that arouses, guarantees the quality AND operation person operational safety of axletree turning, has improved production efficiency.
Description
Technical field
The utility model relates to support and the location of gear-box when rail truck axletree is processed.
Background technology
When axletree carries out turnery processing, due to the lasting rotation of axletree, cause gear-box internal gear High Rotation Speed, add that again gear-box volume weighs greatly, therefore the gear-box supporting and positioning device that need one are firm.Traditional method supports with wooden unit, is placed on by wooden unit on lathe track, the axletree overhead traveling crane of band gear-box carried out handling, after adjusting axle center height, is fallen on wooden unit by gear-box.This method not only labour intensity is large, and wooden unit intensity is low, the compressing of gear-box very easily causes the damage of wooden unit (fall block, upper surface is unequal), add that wooden unit cannot fixation on lathe track, thus aggravation gear-box rocks, and have a strong impact on axletree turning quality, and the play of wooden unit very easily causes the hidden danger of personal security, cause a large amount of doing over again and the waste of manpower and materials, lean beat demand can not be met.
Summary of the invention
Technical problem to be solved in the utility model is, overcome the turning quality difficulty existed in existing axletree turning process and control, labour intensity is large, very easily causes the defect of personal security hidden danger, provides a kind of gear-box supporting and positioning device.
In order to solve above technical problem, the gear-box supporting and positioning device that the utility model provides, it is characterized in that: comprise roller trolley, described roller trolley is fixed with center nut, the upper plane of center nut is by the shaking tray of plane bearing connection with crank, described shaking tray and center nut all offer screw, and leading screw screws in the screw of described shaking tray and center nut, and the top of described leading screw is connected with the support platform for support teeth roller box.
When the utility model effectively can ensure that axletree processing rotates, gear-box supports steadily, gear-box internal gear operates steadily, reduce because gear-box rocks the axletree circular runout phenomenon caused, ensure quality and operator's processing safety of axletree turning, improve production efficiency.
The utility model also has following improvement:
1, described roller trolley has the roller being suitable for carrying out in orbit sliding.
2, described roller trolley also has roller locking mechanism.
Utilize the principle of drving sprial mechanism, center nut is motionless, rotate the adjustment that crank can realize support platform height, can according to the height of the different adjustment support platform of gear box height, thus make bottom gear-box closely connected with support platform, reach the stationarity of support, avoid rocking of gear-box.In order to easier rotation crank, crank lower plane and plane on center nut adopt plane bearing to be connected.In addition, this bottom of device adopts roller trolley, can move freely, can regulate arbitrarily the position of dolly, and trolley idler wheels has the function of locking, can ensure the firm position of gear-box during axletree turning according to the difference of gearbox position along track.
The beneficial effects of the utility model are as follows: decrease axletree turning front gear box positioning time, reduce labour intensity, avoid the instability of wooden unit support, affect turning quality and the potential problem that there is personal security, improve chassis lean production, meet beat-type technological process, improve operating efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is gear-box supporting and positioning device structural representation.
Number in the figure is schematically as follows:
1-support platform; 2-leading screw; 3-shaking tray; 4-plane bearing; 5-center nut; 6-roller trolley.
Detailed description of the invention
As shown in Figure 1, the present embodiment gear-box supporting and positioning device, comprises roller trolley 6, and roller trolley 6 has the roller being suitable for carrying out in orbit sliding, and the locking mechanism of locking roller.Roller trolley 6 is fixed with center nut 5, the upper plane of center nut 5 connects the shaking tray 3 with crank by plane bearing 4, shaking tray 3 and center nut 5 all offer screw, leading screw 2 screws in the screw of shaking tray 3 and center nut 5, and the top of leading screw 2 is connected with the support platform 1 for support teeth roller box.
This device adopts drving sprial formula support platform.By shake crank, regulate support platform upper-lower height, ensure bottom gear-box steadily closely connected with platform.By locking roller trolley behind location, when can realize turning, gear-box fixedly positioning.Effectively decrease rocking of gear-box.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (3)
