Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be further described:
Embodiment 1
Referring to shown in Fig. 1, is the schematic diagram of the tool changing device for machine cutter holder of this creation, and this creation comprises pedestal 10, clamping device 20 and a positioner 30.
Pedestal 10, be that side arranges a fixed part 11, it has a spatial accommodation 12.
Clamping device 20, system is hubbed on pedestal 10, clamping device 20 can move by opposite base 10 between a primary importance and the second place, clamping device 20 is in order to clamp the broach shell 21 that can accept cutter, and clamping device 20 comprises axostylus axostyle 22 and one first oil hydraulic cylinder 23, the both sides of broach shell 21 have one first draw-in groove 211 and one second draw-in groove 212 respectively, and the both sides of axostylus axostyle 22 set firmly a substrate 24 and side plate 241 respectively, first oil hydraulic cylinder 23 is arranged between substrate 24 and side plate 241, and be provided with two guide rods 25 being parallel to axostylus axostyle 22 between substrate 24 and side plate 241, in order to guide the first oil hydraulic cylinder 23 relative to slippage on axostylus axostyle 22, can clamp or discharge broach shell 21 to make clamping device 20.
Positioner 30, system be arranged on pedestal 10, in order to clamping device 20 in the second place time, restriction clamping device 20 traversing, positioner 30 comprises the locating hole 31 that is arranged at the side of the fixed part 11 of pedestal 10, and the pneumatic cylinder 32 of a corresponding locating hole 31.
One second oil hydraulic cylinder 40 is the bottom being arranged at pedestal 10, moves in a rotative pattern between primary importance and the second place in order to order about clamping device 20 opposite base 10.
Consult shown in Fig. 2, be that the clamping device of this creation is in release broach shell schematic diagram, clamping device 20 also includes fixed clip 26 and a movable folder 27, fixed clip 26 is fixedly arranged on the side of the first oil hydraulic cylinder 23, movable folder 27 to be hubbed on axostylus axostyle 22 and relative to the another side of the first oil hydraulic cylinder 23, fixed clip 26 has a card division 261 and establishes the first draw-in groove 211 in order to card, and movable folder 27 also has a card division 271 and establishes the second draw-in groove 212 in order to card.
Consult shown in Fig. 3 and Fig. 4, when clamping device 20 is positioned at primary importance, establish when the first oil hydraulic cylinder 23 opposite shaft 22 is sliding, first oil hydraulic cylinder 23 is moved toward side plate 241 direction, fixed clip 26 moves with the first oil hydraulic cylinder 23, the first draw-in groove 211 is arranged in make the card division 261 of fixed clip 26, and the first oil hydraulic cylinder 23 moves a segment distance to hold the end of movable folder 27, movable folder 27 is pushed and pivot pendulum, its card division 271 is made to be arranged in the second draw-in groove 212, therefore, fixed clip 26 synchronously can be held on broach shell 21 with the start of single first oil hydraulic cylinder 23 of movable folder 27 mat, so broach shell 21 firmly can be positioned middle position, avoid broach shell 21 accept cutter that vibrations produced was crooked, cause the situation of broach shell 21 and member impacts, also there is the effect of the usage quantity simplifying drive member.
Consulting shown in Fig. 5, is that this creation clamping device is positioned at second place schematic diagram, after ordering about clamping device 20 opposite base 10 90-degree rotation by the second oil hydraulic cylinder 40, to make clamping device 20 include in spatial accommodation 12, to carry out tool changing operation.
Consult shown in Fig. 6, it is this creation positioner illustrative view, due in clamping device 20 opposite base 10 rotary course, broach shell 21 perhaps still has slightly crooked situation to occur, the pneumatic cylinder 32 that can pass through positioner 30 extends rod portion 321 fast, with the broach shell 21 of conflicting crooked, broach shell 21 Fast Correction is made to be positioned tram, and make bar portion 231 be positioned locating hole 31, as which limit the traversing of clamping device 20, also avoid broach shell 21 and cutter in cohesive process, cause the damage situation of mechanism member because of collision.
In sum, the tool changing device for machine cutter holder of this creation, system utilizes the first oil hydraulic cylinder synchronously fixed clip and movable folder to be held on broach shell, so that broach shell is firmly positioned at middle position, exempt broach shell crooked and cause situation that is easy and mechanism member collision, moreover, when after the clamping broach shell of clamping device, rotate to the second place relative to pedestal, can pass through the conflict broach shell edge fast, bar portion of the pneumatic cylinder of positioner, so that broach shell is positioned tram, also the vibrations of clamping device generation in time rotating can be exempted, the situation that institute causes broach shell crooked, avoid occurring not broach shell just to collide the possibility of mechanism member.
It will be recognized by those skilled in the art, under the prerequisite not departing from protection scope of the present invention, various amendment, change and combination can be carried out to above-mentioned embodiment, and think that this amendment, change and combination are within the scope of originality thought.
