Abstract
The utility model relates to a structural improvement of a pneumatic pick, and belongs to the technical field of a pneumatic tool. The pneumatic pick comprise a cylinder, a slide valve arranged on the upper part of the cylinder, a hammer body arranged in the cylinder, and a pick rod arranged on the bottom of the cylinder. The utility model is characterized in that the cylinder is composed of an outer cylinder sleeve and a cylinder body tightly fixed in an inner hole of the cylinder sleeve. The outer circle surface of the cylinder body is provided with a vent groove. Since the cylinder is divided into the cylinder sleeve and the cylinder body, an airflow passage can be milled and processed on the surface of the cylinder body. Therefore, in theory, the depth of the assembled airflow passage is unlimited. Accordingly, the utility model provides conditions for increasing the movement range of the hammer body and enhancing the work efficiency of the pick rod.
Description
Technical field
The utility model relates to a kind of gas pick, and especially a kind of architecture advances of gas pick belongs to the pneumatic tool technical field.
Background technology
Gas pick is a kind of hand-held pneumatic instrument commonly used, mainly by cylinder, be installed in air inlet place, cylinder top guiding valve, be placed in the hammer body that can move up and down in the cylinder, the pick rod that is placed in cylinder bottom is formed.During use, be power,, hammer body moved back and forth, impact pick rod by the switching controls gas channel of guiding valve and hammer body position with compressed air, thereby with the fragmentation of hitting object.
The applicant discovers that according to years'experiences the cylinder of existing gas pick is an overall structure, and the pore on the cylinder body is made by drilling processing, and the degree of depth is limited, has therefore limited the movement travel of hammer body.In addition, also there are problems such as hammer body and cylinder body wear and tear easily, the pick rod spring comes off easily in existing gas pick.
The utility model content
The utility model wants the technical solution problem to be: the cylinder body pore problems of drilling that exists at above prior art, and by improvement to air cylinder structure, propose that a kind of hammer body movement travel can significantly strengthen () efficient gas pick.
In order to solve above technical problem, efficient gas pick of the present utility model comprises cylinder, be installed in the guiding valve on cylinder top, be placed in hammer body in the cylinder, be placed in the pick rod of cylinder bottom, its improvements are: described cylinder is made of the cylinder block that the cylinder jacket and the close-fitting of outside is fixed in the cylinder cover inner hole, and the outer round surface of described cylinder block is shaped on air channel.
Understand easily, because cylinder is decomposed into cylinder jacket and cylinder block, therefore gas channel can be taked to make in the mode of cylinder block surface Milling Process, therefore in theory, the gas channel degree of depth that forms after assembling is unrestricted, thereby is that the movement travel of increase hammer body, raising pick rod task performance have been created condition.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Embodiment one
Present embodiment is the efficient gas pick of a kind of cross handle formula, its structure as shown in Figure 1, an end of cross handle is a fixed handle 4, and air inlet bolt 1, back-up ring 2 and torsion spring 3 wherein are housed; Other end plug-in mounting is equipped with flexible handle 5 by transposition pin 7 and the relatively-stationary rotary spool 6 of fixed handle in the rotary spool 6, thereby constitutes rotary switch.Cross handle grips connection with cylinder by connector 8, head flanges 13 under the effect of stay bolt 17.Cylinder is made of the cylinder block 10 that the cylinder jacket 11 and the close-fitting of outside is fixed in the cylinder cover inner hole, and the outer round surface of cylinder block 10 is shaped on air channel.The top and the valve body of cylinder block 10 are connected as a single entity, and guiding valve 9, middle part arrangement hammer body 12 wherein are installed, the bottom () head flanges 13 places installation pick rod.The cylindrical of hammer body 12 is coated with engineering plastics antifriction cover, and therefore, cylinder block 10 can be used the ordinary carbon steel manufacturing, even long-term the use, also (meeting) is not easy to wear.The outer head springs upper end of pick rod is shaped on notch, by pin 14 eccentric wheel 15 that can be stuck in described notch is housed on the head flanges 13, even therefore impact shock, head springs can not get loose yet.
During use, after installing pick rod for gas pick, hand-held gas pick handle, pick rod is against hit on the thing, finger is stirred rotary switch, and compressed air enters the connector inner chamber from the air inlet screw by switch, by moving up and down of guiding valve compressed air is allocated in the cylinder block two ends in turn again, hammer body promptly comes and goes ballistic motion, impacts pick rod and makes the pick rod work done.When unclamping the rotary switch handle, rotary spool automatically resets under the effect of torsion spring, and compressed air is blocked, the hammer body stop motion.
Conclusion is got up, and present embodiment has following design feature:
1) adopts normally closed type rotation air cock, reach the purpose of open and close with less corner; Functional unit is in the airtight relatively structure helps preventing dust, reduce the wearing and tearing of functional unit, guaranteed motion freely from structure.
2) adopt cylinder split design, the cylinder of Primordial Qi pick is formed port by a part be arranged on the method that adopts depth drill system on the cylinder wall, the cylinder that is designed to gas pick is made up of cylinder block and cylinder lagging.Cylinder block is selected seamless steel pipe milling air drain or directly hot investment casting moulding in the unit outside it for use, then cylinder jacket is inserted in cylinder block with certain quality of fit, thereby forms a cylinder assembly that does not need depth drill system port.This is for the lengthening cylinder, and the imagination that increases the power of hammer body movement travel raising gas pick becomes possibility, has solved the technology difficult problem of gas pick gun drilling processing.
3) structure of gas pick has been simplified in the integrated design of cylinder block and valve body, and it is loosening in vibrations to stop part, reduces the gas that produces therefrom and leaks the mutual impact between gentle pick self part, the too early damage.Hammer body flange end is from the head packed into.
4) hammer body adopts the antifriction Analysis of Nested Design, is inlaid with the antifriction cover that special engineering plastics is made in the outer unit of hammer body.So, the cylinder of gas pick can adopt general carbon steel manufacturing and need not to consume in a large number steel alloy; Also need not simultaneously the cylinder processing of quenching, the manufacturing energy consumption of having saved resource greatly, having saved unit product.
5) head springs has the eccentric wheel stop device.Head springs is that gas pick in use plays the function of helping pick rod.In use make troubles owing to becoming flexible to revolve to take off to the user.Present embodiment adopts the eccentric wheel principle, during non-installment state, eccentric wheel under the effect of gravity naturally downwards.Behind head spring upper end R precession eccentric wheel, pressure angle of eccentric wheel and the formation of head springs R place, thus make it can't revolve to move back and get loose.When needs revolve when moving back, if with head springs forward precession a little, the eccentric wheel that press...withes one's finger does not allow it fall and gets final product.Consider attached with φ 1mm steel wire for adapting to various working in eccentric wheel one side.Easy for installation, stop is reliable.Also simplified simultaneously the processing and fabricating of head springs.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
