Description

Reciprocal impact type bruin

Affiliated technical field

The utility model belongs to carving and pecks technical field of tools, and what relate generally to is a kind of reciprocal impact type bruin.

Background technology

At present, the domestic and international carving that uses in engraving fields such as technology gardens pecks instrument and is still traditional chisel, bell and icking tool etc. basically, because these instruments mainly are to carve article by manpower or with the impulsive force that hammer impacts generation in use, thereby have that production efficiency is low, labour intensity is big, tool wear is serious, the replacing instrument is frequent and drawback such as not easy to operate.

Summary of the invention

The purpose of this utility model promptly produces thus, proposes a kind of reciprocal impact type bruin, thereby effectively increases work efficiency, and reduces labour intensity, prolongs the service life of instrument.

For achieving the above object, the utility model is achieved through the following technical solutions: it is by graver and be arranged on drive link in the sleeve pipe, spring, fairlead, yoke, permanent magnet, magnetostrictive rod and solenoid constitute, the front end of the drive link graver outer with being arranged on sleeve pipe is connected, the center that the rear end has positioning step and a rear end has the boss to outer lug, fairlead is the Portuguese bowline structure, be enclosed within on the drive link and drive link is moved back and forth along it, positioning step of the following end distance drive link of cover has the gap in it, spring housing puts in fairlead, one end of sleeve pipe inserts two inner rooms of fairlead and spring is positioned between fairlead cover and sleeve pipe, two ends at magnetostrictive rod are equipped with yoke, the yoke of one end is arranged on drive link between the boss and magnetostrictive rod of outer lug, the yoke of the other end is arranged between sleeve bottom and the magnetostrictive rod, outside yoke, be equipped with permanent magnet, solenoid is arranged on outside the magnetostrictive rod, and the lead of this solenoid is drawn by sleeve pipe and connect power supply.

The utility model utilizes the magnetostriction bar material can produce the characteristic of deformation under magnetic field effect, and by laying a solenoid in the magnetostrictive rod periphery, and a logical electric current forms powerful magnetic field, acts on magnetostrictive rod, makes it increase by one vertically

Promote drive link and icking tool and impact the article of being carved, this moment, spring was compressed; When the current interruptions in the coil, magnetic field disappears, and magnetostrictive rod returns to original length, by spring drive link and graver is reset to the origin-location, finishes a double vibrations impact process.Because the power supply of solenoid is an AC frequency modulation, pressure regulation electric current, a tuning range reliability service between tens Hz-hundreds of KHz, therefore, determines the vibration frequency of system; By adjusting the increment of Control of Voltage magnetostrictive rod, realize that the purpose of adjusting amplitude and exciting force is easy to realize.The permanent magnet that is provided with, is not fully exerted the performance of magnetostrictive rod, and plays the effect that saves energy to the additional bias magnetic field of magnetostrictive rod by prefabricated powerful magnetic field.By front end mosaic gold hard rock, improve service life at graver.Can increase work efficiency more than the 2-8 with these reciprocating type impact bruin engraving article, reduce the amount of labour 80%, and the service life that can improve instrument more than 10 times, the replacing trimming time that shortens instrument is more than 90%.

The specific embodiment

In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:

As shown in Figure 1, present embodiment is made of graver 1 and the fairlead 3, spring 4, drive link 14, permanent magnet 5, yoke 10, magnetostrictive rod 6 and the solenoids 13 that are arranged in the sleeve pipe 7, drive link 14 is rectangular cross section or hexagonal cross-section (as shown in Figure 2), its front end center has whorl brace rod, be threaded with the graver 1 outside being arranged on sleeve pipe 7, promptly be provided with the internal thread connecting hole in the rear end of graver 1, graver 1 is threaded with whorl brace rod on the drive link 14 by this internal thread connecting hole.The center that the rear end of drive link 14 is provided with positioning step and rear end has the boss to outer lug.Fairlead 3 is enclosed within on the drive link 14, and this fairlead 3 is the Portuguese bowline structure, has to make drive link reciprocating direction location and caput and drive link that the dual-use function of locking is installed.The fit system of itself and drive link 14 can adopt cylinder to add the mode of keyway, positioning key, also can adopt modes such as rectangular cross section, hexagon or elliptic jet.In drive link 14, put and be with spring 4, the front end of sleeve pipe 7 inserts in two covers of fairlead 3, and make spring 4 between the interior cover and sleeve pipe 7 of fairlead 3, and the interior cover of fairlead 3 and the positioning step of drive link have a gap, and this gap should be greater than the reciprocal distance of impacting of icking tool.The two ends of magnetostrictive rod 6 are equipped with yoke 10, and effect is to guarantee that magnetostrictive rod is stressed evenly, thus the service life of improving magnetostrictive rod, and have the magnetic conduction effect.The yoke 10 of magnetostrictive rod 6 front ends is arranged on drive link 14 between the boss and magnetostrictive rod of outer lug, and the yoke 12 of rear end is arranged between sleeve pipe 7 inner bottom parts and the magnetostrictive rod.Be equipped with permanent magnet 5 outside yoke 10,12, this permanent magnet 5 is a circulus, is enclosed within outside the yoke.Solenoid 13 is located at outside the magnetostrictive rod 6, it is wound on the skeleton 11 that non-magnet material makes, and its lead-in wire 8 is drawn external power supply by sleeve pipe 7, is provided with terminal plate 9 and connector cover 15 in the rear end of sleeve pipe 7, the outside is provided with rubber finger sleeve 2, is convenient to hand-held and the buffering vibration.The front end of graver 1 can be designed to taper or in-line structure (as shown in Figure 3-4), and studs with diamond, and effect is the service life of improving graver.The utility model in use, when solenoid lead-in wire two ends add a voltage, electric current produces magnetic field simultaneously by coil, act on magnetostrictive rod, it is increased to the right along axis direction, produce thrust, move right by yoke promotion drive link and graver, impact the engraving article, this moment, spring was compressed.When voltage vanishing that solenoid lead-in wire two ends add, electric current by coil stops magnetic field disappearance simultaneously, magnetostrictive rod returns to original state left along axis direction, thrust gradually is zero, this moment, spring promotion drive link and graver were moved to the left, get back to relative initial position, finish an oscillatory surge cycle.When solenoid lead-in wire two ends add be alternating voltage the time, electric current by coil is an alternating current, produce action of alternating magnetic field simultaneously in magnetostrictive rod, make it along the axis direction side-to-side vibrations, drive drive link and graver simultaneously and also carry out side-to-side vibrations, the powerful carved object that impacts of its graver reaches the purpose of carving article.
