Abstract
The utility model discloses a differential pressure valve spring adjusting device, which is characterized in that the adjusting device comprises a main bar and a guide seat; the front end of the main bar, which is composed of a short column and a long column, is step-shaped; a full-length step hole is formed in the guide seat; and the front end of the main bar is in clearance fit with the step hole in the guide seat. The adjusting device can conveniently adjust the elastic force of the spring, particularly adjust the elastic force of a vehicle differential pressure valve spring, is simple for operation, has a small volume, is convenient for storage, greatly improves the work efficiency, and saves human resources and material resources at the same time.
Description
Technical field
The utility model relates to a kind of passenger train defferential valve inner spring regulating device, especially can adjust the device of spring force easily.
Background technique
When defferential valve carries out the test stand performance detection, the serious overproof quality of lot problem of defferential valve working value once took place, it is former because defferential valve inner spring elastic force value exceeds critical field, because production task is tight, and defferential valve all is an import parts, makes spring again and is dealt into domesticly again, needs very long period, can't satisfy production requirement, not guarantee friendship car task.
The model utility content
Technical problem to be solved in the utility model is to guarantee to make the defferential valve working value meet standard-required under the prerequisite of production task, thereby a kind of convenience, time saving and energy saving and can adjust the regulating device of defferential valve spring force is provided.
For solving the problems of the technologies described above, the utility model provides a kind of spring adjusting device, it is characterized in that: comprise mobile jib and guide bracket, the mobile jib front end constitutes step-like by short cylindrical and long cylinder, have elongated step hole in the guide bracket, step hole Spielpassung in mobile jib front end and the guide bracket.
The utility model can be adjusted spring force easily, and for the adjustment of vehicle defferential valve spring force, this regulating device is simple to operate, volume is small and exquisite, keeping is convenient, has greatly improved working efficiency, simultaneously, has saved the man power and material especially.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
With reference to accompanying drawing, the utility model comprises mobile jib 1 and guide bracket 5, and the mobile jib front end is made of step-like short cylindrical 2 and long cylinder 3, have elongated step hole 4 in the guide bracket, step hole Spielpassung in mobile jib front end and the guide bracket.
When carrying out the adjustment of defferential valve spring force, spring housing is gone on the mobile jib 1, spring one end is positioned by the short cylindrical 2 of mobile jib 1 front end and the step of long cylinder 3 formations, again mobile jib 1 is packed in the guide bracket 5, the spring the other end is positioned by step hole in the guide bracket 5, make mobile jib 1 and guide bracket 5 thresh relative movement with hand or other external force, make spring in constantly compression and elongation, and then the spring free height obtains small adjustment, because of there are causality in spring force and spring free height, the final result spring force has obtained adjustment, the defferential valve working value has met standard-required, and detect its stable performance by continuous tracking to first batch of adjusted defferential valve a year and a half, meet standard-required.So, realized adjustment to spring force by spring adjusting device.
