Abstract
The invention provides an automatic positioning mechanism of a steel rail. Two sides of the steel rail are clamped by using a bearing 5, and the surface hardness of the bearing is high, therefore, the abrasion resistance between the bearing and the steel rail is improved; one side of the bearing is positioned, and the other side of the bearing can be automatically adjusted on a connecting rod 4 and always clamps the steel rail; the connecting rod is rotated by taking an intermediate shaft 8 as a pivot and a spherical gasket 3 as an adjusting point to realize any angle within a small range; and a disc spring 2 is used for providing an automatic clamping force, and the excellent positioning performance of the bearing on the steel rail can be ensured after the disc spring is adjusted, and meanwhile, the bearing can freely roll and run. The automatic positioning mechanism is mainly used for automatically positioning the device on the steel rail in a gapless way.
Description
Technical field
The invention belongs to plant equipment, be mainly used in automatic location rail.
Background technology
In the design that rail is in the past located and clamped, what adopt is inboard two bearings location, outside two bearings eccentric shaft structure, this kind structure is having relatively high expectations to processing on the one hand, and eccentric adjustment amount is generally all in 1.5mm, so cause very big difficulty to installing to adjust when rail is very long, because the straightness accuracy of rail is all in 2mm under the normal condition.On the other hand, under the improper crooked situation of rail, very easily cause the stressed excessive of bearing, make eccentric change, and between the bearing that clamps, produce the gap, and influence the precision of machine, on the other hand,, the rail face is squeezed hinder because of being subjected to bigger power.
The objective of the invention is to, the nut on the linkage leading screw that utilization adjusting connecting rod right side is used for clamping makes bearing that suitable clamping force be arranged, and to guarantee frame good steering capability is arranged, and moves freely again simultaneously.
Summary of the invention
Major programme of the present invention is achieved in that
The present invention mainly adopts connecting rod, screw mandrel, dish spring to be connected on the equipment rack, bearing of fixing on the connecting rod and the bearing on the frame clamp vertical rail by the adjusting of screw mandrel, and the nut on the adjusting connecting rod just can be applied to power on the dish spring on the screw mandrel, thereby the angle of adjusting connecting rod makes bearing clamp rail all the time.
The specific embodiment
Be further described below in conjunction with the example in the accompanying drawing:
The present invention mainly is made up of parts such as screw mandrel 1, dish spring 2, spheric washer 3, connecting rod 4, bearing 5, minor axis 6, major axis 7, jackshafts 8.
Screw mandrel 1 one ends are fixed on the side plate of frame, and the other end links to each other with connecting rod 4 by the contact of spheric washer 3, utilize dish spring 2 and nut that screw mandrel 1 and connecting rod 4 is fixing.The center of connecting rod 4 is fixed on the base plate vertical with the machine side plate by jackshaft 8, connecting rod 4 floats, can center on jackshaft 8 rotating certain angle, connecting rod 4 other ends have major axis 7, bearing on the minor axis on one location bearing and the frame is arranged together with the location, rail side of machine on the major axis 7.Adopt this elastic construction, after minor axis was effectively located rail, the bearing on the major axis 7 was by regulating, all the time be in contact condition with rail, dish spring 2 can clamp at rail and realize under the situation of dimensional variations regulating automatically, and compares with eccentric shaft structure, and the gap of adjusting is bigger.
Description of drawings:
Fig. 1 always schemes for detent mechanism of the present invention
Fig. 2 is the structure chart of connecting rod 4
Fig. 3 is the structure chart of spheric washer 3.
Claims (3)
1. detent mechanism, adopt connecting rod (4) to be fixed on the frame by jackshaft (8), one end of connecting rod adopts leading screw (1) and dish spring (2), spheric washer (3) and the frame vertical with jackshaft to fix, and the other end has the bearing on the major axis (7) parallel with jackshaft (8) to make the rail location.
2. a kind of detent mechanism according to claim 1 is characterized in that described adjustment constitutes an end of connecting rod with nut and dish spring (2) and spheric washer (3).
3. a kind of detent mechanism according to claim 1, the other end that it is characterized in that using fixing major axis (7) and bearing (5) to constitute connecting rod (4).
