Abstract
The utility model discloses a kind of anti-lock hydraulic breaking hammer piston, includes the body of rod, and body of rod one end is strike position, and the other end is piston fixed position, and body of rod middle is piston compensating groove, and piston compensating groove periphery offers axial U-type groove.The lubricity that the utility model is effectively increased between cylinder body and piston reduces friction coefficient, and U-type groove plays the role of draining, effectively improves this point, so as to greatly improve production efficiency.
Description
Technical field
Hydraulic crushing field is the utility model is related to, particularly a kind of anti-lock hydraulic breaking hammer piston.
Background technology
Hydraulic breaking hammer is formed by numerous assembling parts, each part plays the role of vital, hydraulic crushing
Hammer piston is the core part that high intensity, high vibration and high-frequency impact energy are produced after hydraulic-driven is subject to, its is durable
Degree and raising hitting dynamics are just particularly important, once it can make in hydraulic breaking hammer by lateral force or chip off-falling deformation
Cylinder body and reversal valve pull locking, cause whole hydraulic breaking hammer to be scrapped, or even badly damaged hydraulic pump of excavator.Thus can make
Delay into huge economic loss and seriously normal production.
Utility model content
The utility model provides a kind of anti-lock hydraulic breaking hammer piston, and improve hydraulic breaking hammer uses the longevity
Life, adds hitting dynamics.
The technical solution of the utility model：
Anti-lock hydraulic breaking hammer piston, includes the body of rod, and body of rod one end is strike position, and the other end is fixed for piston
Position, body of rod middle are piston compensating groove, and piston compensating groove periphery offers axial U-type groove.
The wide 6-20mm of the U-type groove, depth 1.5-3mm, long 30-50mm, quantity are 4.
The advantages of the utility model：
1. the lubricity effectively increased between cylinder body and piston reduces friction coefficient.
2. piston impact drill steel is subject to lateral force, the verticality of piston up-down can be adjusted rapidly, significantly
Reduce and pull risk between piston and middle cylinder body, so as to extend the service life of hydraulic breaking hammer.
3. piston is moved up and down in middle cylinder body with 600-1000 high-frequencies per minute impacts drill steel, often cause under piston
The difficult situation not come is removed, U-type groove plays the role of draining, effectively improves this point, so as to greatly improve production
Efficiency.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
As shown in the figure 1, anti-lock hydraulic breaking hammer piston, includes the body of rod 1, and 1 one end of the body of rod is strike position 2, separately
One end is piston fixed position 3, and 1 middle of the body of rod is piston compensating groove 4, and 4 periphery of piston compensating groove offers the U of 4 axial directions
Type groove 5, the width of U-type groove 5 6-20mm, depth 1.5-3mm, long 30-50mm.
After piston heat treatment, with using CNC milling machine, special metals milling cutter is process, and is set using special grinding
It is standby to carry out deburring and chamfering.
Claims (2)
1. anti-lock hydraulic breaking hammer piston, it is characterised in that：Include the body of rod, body of rod one end is to hit position, the other end
