Specific embodiment
To make to have further understanding to the purpose of the present invention, construction, feature and its function, hereby cooperate embodiment detailed
It is described as follows.
Please refer to Fig. 1 and Fig. 2.A kind of electromagnetic piston type tool changing device of one embodiment of the invention, as shown in Figure 1,
Including tool change arm 1 and tool changing hand 2, in exchanging knives process, tool change arm 1 can around rotary shaft at its center rotate and on move down
Dynamic, two tool changing hands 2 are located at the both ends of tool change arm 1, and tool changing hand 2 is for clamping cutter.The both ends of tool change arm 1 penetrate through respectively
A holding holes are offered, are installed with tool changing hand 2 in two holding holes.
As shown in Fig. 2, tool changing hand 2 includes grip slipper 21, elastic component 22, piston 23, supporting piece 24 and electromagnet 25.Clamping
Seat 21 constructs for T-type, and the holding holes of tool change arm 1 are fixed in the annular flange support that grip slipper 21 is relatively large in diameter by the upper end
In.Perforation offers multiple pilot holes 211 on the peripheral wall of 21 lower part of grip slipper, pilot hole 211 grip slipper 21 peripheral wall it is same
One height was distributed around grip slipper one week.It is actively installed with supporting piece 24 in each pilot hole 211, in the present embodiment, supports
Gripping member 24 is steel ball.Due to the shape that pilot hole 211 is the small two sides perforation of interior big mouth, 24 both ends of supporting piece are extended to assembly
Two outsides in hole 211, but supporting piece 24 can not be deviate from out of pilot hole 211, to enable supporting piece 24 relative to clamping
Seat 21 moves left and right in a certain range.
Elastic component 22, piston 23 and electromagnet 24 are sheathed on the periphery of grip slipper 21.Wherein, the both ends of elastomer 22
It is flexibly supported respectively with electromagnet 24 and piston 23, piston 23 can be that guiding moves up and down with grip slipper 21.
Electromagnet 24 is annular, and including annular core and the coil for being wound in iron core, electromagnet 24 can be fixed by iron core
It is arranged in the groove of grip slipper 21 or fixing card is set in the groove of the holding holes of tool change arm 1, the purpose is to make electromagnet
24 are kept fixed position relative to piston 23, and when coil and external dc power connection, electromagnet 24 generates magnetic field, the magnetic field
Piston 23 can be attracted, the elastic force for making piston 23 overcome elastomer 22 moves up, also, passes through the electric current and the elasticity of compression of coil
There are substantial linear corresponding relationships between the size of power needed for body 22, i.e. electric current in coil is bigger, and the magnetic field strength of generation is got over
Greatly, also bigger to the suction of piston 23.
Piston 23 is sheathed on grip slipper 21, and the upper end of piston 23 leans with elastomer 22 and supporting piece 24, piston 23
Lower end elastomer 22 elastic force effect under be resisted against on tool change arm 1.For guarantee electromagnet 25 to the attraction effect of piston 23,
Piston 23 can be made of ferrimagnet and shape is annular.
In addition, the magnetic field in order to avoid electromagnet 25 has an adverse effect to elastomer 22, elastomer 22 can be by by magnetic
The nonferromugnetic material that field influences is made, and elastomer 22 can be helical compression spring, be also possible to disk spring.
The working principle of the electromagnetic piston type tool changing device is, when not needing clamping cutter, in the coil of electromagnet 25
Obstructed electric current, electromagnet 25 do not generate magnetic field, at this point, piston 23 is located at bottom, piston under the elastic force effect of elastomer 22
23 do not squeeze supporting piece 24, and supporting piece 24 can be move freely left and right in pilot hole 211, and cutter can smoothly enter grip slipper
It is exited in 21 internal cavities or from the internal cavities for holding seat 21；When needing to clamp cutter, the clamp groove of cutter with support
The position of gripping member 24 corresponds to each other, and electric current is passed in the coil of electromagnet 25, and electromagnet 25 generates magnetic field, magnetic field suction piston
23, piston 23 overcomes the elastic force of elastomer 22 to move up and gradually squeezes supporting piece 24, extruding of the supporting piece 24 in piston 23
It is lower mobile to the clamp groove direction of cutter, and realize the clamping to cutter.
Compared with prior art, when needing to clamp cutter, piston 23 overcomes 22 elastic force of elastomer gradually to squeeze supporting piece
24 clamp-on tools will not generate generation shock in the clamping process of cutter, can prevent the abrasion of cutter and tool changing hand 1, deformation and
Damage, and tool-changing speed is faster.When loosening cutter, piston 23 is resetted in the case where the elastic force of elastomer 22 pushes, and makes supporting piece 24
Loosening cutter, loose knife will not generate generation shock in the process.In addition, cutter executes clamping by several supporting pieces 24 and locking is dynamic
Make, acted independently of each other between each supporting piece 24, individual failures of supporting piece 24 not will cause entire tool changing device can not be just
Often work, equipment safety operation coefficient are high.Meanwhile the locking action of cutter by electromagnet 25 drive realize, can effectively avoid by
Cutter can not be locked caused by the reasons such as spring aging, fracture and falls knife phenomenon.
The present invention is described by above-mentioned related embodiment, however above-described embodiment is only to implement example of the invention.
It must be noted that the embodiment disclosed is not limiting as the scope of the present invention.On the contrary, do not depart from spirit of the invention and
It is changed and retouched made by range, belongs to scope of patent protection of the invention.
