Description
Technical field
The utility model belongs to undergauge equipment technical field, more particularly, to a kind of novel reducing device.
Background technology
Bush type damper is mainly used in machinery field, most common, is the industries such as automobile, motorcycle, and bush type subtracts
The rubber material of shake device itself has many advantages, such as light weight, shock resistance and easily absorbs high-frequency vibration, in addition rubber and metal bond
The raising of technology, bush type damper are widely used in the support group parts such as automotive suspension, can allow vehicle frame and vehicle body
Vibration velocity slow down.
Bush type damper is cold after the completion of vulcanization since there are certain thermal contractions for heating in producing sulfidation
There are gaps for rubber interlayer when but getting off, and tensile strength is inadequate, and to reduce the internal stress that rubber generates, improving the fatigue of product makes
It with performance, meets customer need, so needing to carry out undergauge processing to such cushioning product after the completion of vulcanization, application is answered in advance
Power keeps rubber arrangement finer and close, improves fatigue strength, extends the service life of metal and rubber assembly.
But it in the prior art, needs to be pressed downward by press mostly when carrying out undergauge operation, the stroke of such oil cylinder is long, whole
Gymnastics work is slower, and a product need to make a set of reducing device, not only cost of idleness, and operation and maintenance gets up all quite
Cumbersome, product takes out difficult, low production efficiency.
Invention content
Problem to be solved in the utility model is to provide a kind of compact-sized, and swift to operate, stroke is short, versatility and production
Efficient novel reducing device.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of novel reducing device, including cylinder
Body, the cylinder interior are provided with piston, and the cylinder side wall positioned at piston side is provided with hydraulic fluid port；Piston upper end center position
It installs and is equipped with more valve voussoirs, more valve voussoirs are surrounded by class circular ring shape undergauge structure, pass through spring phase between voussoir and voussoir
Even；It is provided with the V-arrangement guide ring being matched therewith on the outside of the voussoir, which is provided with gland.
The cylinder body upper end is provided with screwed adjustable knob, and the adjustable knob is connected through a screw thread with gland,
The adjustable knob can drive gland to move up and down.
The internal piston is provided with mandrel, and the mandrel and the class circular ring shape undergauge structure that more valve voussoirs are surrounded by are coaxial
Setting.
The piston outer wall and inboard wall of cylinder block joint, are provided with ring type seal.
The hydraulic fluid port includes oil inlet and oil outlet.
Due to the adoption of the above technical scheme, the utility model is equivalent to increases undergauge tooling, overall structure in oil cylinder
Simple and compact controls the lifting of piston, piston lifts the lifting that can drive V-arrangement guide ring, more by the oil inlet and oil extraction of hydraulic fluid port
The class circular ring shape undergauge structure that valve voussoir is surrounded by is located on the inside of V-arrangement guide ring, is connected by spring between voussoir and voussoir, work
When making, the class circular ring shape undergauge structure that more valve voussoirs are surrounded by is scattered, and is put the workpiece at this time, and piston rises, and squeezes contracting
Gauge structure is closed, and completes to squeeze the undergauge of workpiece, stroke is short, swift to operate, and production efficiency is high；In addition, cylinder body upper end is arranged
There are screwed adjustable knob, the adjustable knob to be connected through a screw thread with gland, which can drive gland or more
Movement, because the stroke of piston is certain, after adjusting gland height, piston is raised to highest point undergauge structure and does not also close completely
It closes, is equivalent to and has adjusted undergauge diameter, increase the versatility of the utility model and convenient for safeguarding.
The utility model has the beneficial effects that：With compact-sized, swift to operate, stroke is short, versatility and production efficiency
High advantage.
