Description
The utility model is to belong to a kind of metal-cutting machine tool, and specifically a kind of Recoilless hydraulic shovel is scraped head, can be used for shoveling the mating surface of scraping the finishing machine components.Blademan in machine-building and repairing trades skill is continued to use manual blademan's tool always, and not only labor strength is big, and work efficiency is low, and is engaged in this work for a long time and can causes occupational disease.In recent years, still the someone attempts to scrape cutter with motor-driven shovel and shovels and scrape cutting, all scrapes recoil in the process because of not eliminating shovel, and the uncontrollable shovel of operator is scraped the position, scrapes a degree of depth and knife mark shape and dies young.
The purpose of this utility model provides a kind of Recoilless hydraulic shovel and scrapes head, utilizes hydraulic actuation power to replace human body to have an effect, and to reduce labor intensity, guarantees the healthy of operator, improves work efficiency and machining accuracy.
Accompanying drawing is the structural representation of a kind of specific embodiments of the utility model.
Number in the figure: 1. shovel scraper head, 2. piston rod, 3. cylinder body, 4. spring, 5. piston, 6. end cap, 7. end cap, 8. crossbeam, 9. plug screw, 10. cylinder body, 11. pistons, 12. springs, 13. check valves, shower nozzles in 14., 15. outer shower nozzle, 16. radiators, 17. pipe joints, 18. oil pipes, 19. holder handles, 20. lining bars.
The technical solution of the utility model is as follows.
The Recoilless hydraulic shovel is scraped head, mainly comprises shovel scraper head, operating cylinder, inverse recoil power cylinder, lining bar, petroleum pipeline, check valve, radiator, interior shower nozzle and outer shower nozzle.The inverse recoil power cylinder is clamped between the two lining bars 20, the crossbeam 8 that its end cap 7 passes lining bar 20 is connected with operating cylinder end cap 6, petroleum pipeline 18 is stretched nearly operating cylinder by the center of inverse recoil power cylinder piston 11, also be connected with end cap 6, the rod end of inverse recoil power cylinder piston 11 then is connected with the crossbeam 8 of lining bar 20.
The utility model is to have an effect for human body for the power band with hydraulic oil, pressure oil in the described operating cylinder is by oil pipe 18 inputs, be marked with Seal Oil in the inverse recoil power cylinder, the recoil that the shovel scraper head is produced when acting on workpiece hydraulic oil in operating cylinder is passed to the inverse recoil power cylinder with the form of kinetic energy, whole course of action is to convert the kinetic energy that recoil produces to heat energy by heat sink radiates, eliminates recoil with this.
The piston rod 2 of operating cylinder stretches out outer one of cylinder body 3 and fixes a shovel scraper head 1, suit one back-moving spring 4 on the body of rod in cylinder body 3, hydraulic oil from hydraulic control box during work is closely gone into operating cylinder from petroleum pipeline 18, promote piston 5, overcome the resistance of spring 4, piston rod 2 is stretched out and feed, and when hydraulic fluid pressure disappeared, back-moving spring 4 forced piston rod 2 withdrawals and withdrawing.Because from control cabinet hydraulic oil is pulse signal,, realize the action of blademan's part so shovel scraper head 1 can be done the quick-expansion motion.The operating frequency that shovel is scraped cutting is consistent with pulse frequency from the pressure oil of control cabinet, generally is selected in per minute and is advisable for 40～60 times.The size that shovel is scraped cutting force is relevant with the diameter of the pressure of hydraulic oil and operating cylinder piston 5, generally be advisable to obtain 50～120kgf, it is relevant that shovel is scraped the internal diameter factors such as (that is piston diameters) of interior feed time of flow, each cycle, operating cylinder of the amount of feeding of when cutting cutter and hydraulic oil, is typically chosen in 0～20mm according to processing object and is advisable.
The recoil of head when reducing machining, the utility model is established a radiator 16 at the other end of inverse recoil power cylinder cylinder body 10, radiator 16 is fin in addition, in establish oil storage cavity, make inverse recoil power cylinder two Room about piston body two forms, suit one back-moving spring 12 on the body of rod of inverse recoil power cylinder piston 11, establish a check valve 13 in the piston body, a distaff body annular spread number jet aperture, aperture with piston body about two Room be communicated with, all filling with hydraulic oil with radiator 16 oil storage cavities in the inverse recoil power cylinder, interspace slightly, and shut with plug screw 9.When the reaction force of workpiece reaches inverse recoil power cylinder cylinder body by operating cylinder, back-moving spring 12 is compressed, inverse recoil power cylinder left chamber body is long-pending to be dwindled rapidly, right ventricle's volume increases rapidly, force hydraulic oil to inject the right ventricle from the jet aperture, in this process, the workpiece reaction force makes the part of kinetic energy that head obtains be transformed into heat energy and distributes by radiator 16.In addition, because the compression of spring 12 and the cushioning effect of hydraulic oil high-speed jet, prolonged the action time of head recoil to human body.So, the recoil that reaches human body reduces greatly, when the reaction force of workpiece disappears, the pressure of chamber, inverse recoil power cylinder left side hydraulic oil disappears thereupon, and under the effect of back-moving spring 12, the oil pressure of right ventricle is higher than left chamber, set check valve 13 is opened in piston 11 bodies, inverse recoil power cylinder cylinder body 10 resets rapidly, waits for the arrival of reaction force next time, makes the inverse recoil power cylinder have the function of eliminating recoil all the time.
Shovel speed and the efficient that the kinetic energy of scraping head acquisition in the process changes heat energy in order to hit further raising, be provided with cavity in the piston body of the utility model inverse recoil power cylinder piston 11, be provided with a shower nozzle 14 and a tubaeform outer shower nozzle 15 in the taper in the chamber, and interior shower nozzle 14 is fixed on the petroleum pipeline 18, and outer shower nozzle 15 is fixed on the chamber wall of piston body internal cavity.During work, outer shower nozzle 15 is fixed on the piston 11 motionless, under the effect of workpiece reaction force, interior shower nozzle 14 and petroleum pipeline 18 follow inverse recoil power cylinder cylinder body 10 to move to right simultaneously and rapidly, interior shower nozzle 14 enters in the horn mouth of outer shower nozzle 15, it forms an annular jet mouth between the two, the hydraulic oil of chamber, an inverse recoil power cylinder left side on piston body the jet aperture and described annular jet mouth with higher speed directive right ventricle, thereby speed and efficient that kinetic energy becomes heat energy have further been improved, and the big more described annular jet mouth of reaction force is more little, it is just fast more that kinetic energy changes the speed of heat energy into, that is it is just big more to eliminate recoil.Therefore the recoil that is transmitted on the human body is very little, and the not linear increase with the increase of reaction force.
Advantage of the present utility model is to eliminate recoil 70%～80%, easy to use, during use, the operator is as long as connect the hydraulic control box power supply, can be sitting in to shovel on the chair and scrape cutting, alleviate working strength of workers widely, shovel is scraped the position, is scraped a degree of depth and knife mark shape and be easy to control simultaneously, can improve 3～4 times of work efficiency, improve 1～2 grade of precision of workpiece.
