The technical solution of the multi-station parallel gripper mechanism according to the invention will be described in more detail below with reference to a schematic drawing, in which a preferred embodiment of the invention is shown, it being understood that a person skilled in the art may modify the invention described herein while still achieving the advantageous effects of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
As shown in fig. 1, 2, 3 and 4, in the present embodiment, a multi-station parallel jaw 10 mechanism for metal processing includes: the hydraulic clamping jaw mounting device comprises an oil cylinder mounting base 1, a plurality of oil cylinders 2, paired guide mounting seats 5, a top-pull inclined wedge 4, paired guide blocks 7, paired translation blocks 6, paired clamping jaw supporting seats 8 and clamping jaws 10.
Specifically, a plurality of mounting positions are arranged on the oil cylinder mounting base 1; each cylinder 2 is fixed in one mounting position. In the present embodiment, the number of the cylinders 2 is 4. The guide mounting base 5 is fixed on the upper part of the oil cylinder mounting base 1 along the length direction of the oil cylinder mounting base 1; the paired guide mounting seats 5 and the oil cylinder mounting base 1 jointly enclose a working cavity, and the top-pull inclined wedge 4 and the translation block 6 are located in the working cavity. The lower end face of the top-pulling inclined wedge 4 is fixedly connected with the output end of the oil cylinder 2 through a screw 3; the upper end surface of the top-pulling inclined wedge 4 is positioned in the working cavity; the top-pulling inclined wedge 4 can move up and down in the working cavity along with the oil cylinder 2; the two sides of the top-pull inclined wedge 4 along the length direction are provided with top-pull inclined grooves 41; the top-pulling inclined groove 41 penetrates through the upper end surface and the lower end surface of the top-pulling inclined wedge 4; the guide block 7 is oppositely arranged on the guide mounting seat 5; in the embodiment, two guide blocks 7 are arranged on one installation position, and the guide blocks 7 are horizontally arranged on the guide installation base 5 so as to ensure that the translation block 6 moves horizontally and ensure the machining precision of a machined workpiece; the translation blocks 6 are bridged between the paired guide blocks 7; the upper part of the translation block 6 is clamped on the guide block 7; the lower part of the translation block 6 is inserted into the top pull chute 41 and is matched with the top pull chute 41; the lower part of the translation block 6 realizes translation in the left-right direction along with the up-down movement of the jacking chute 41; the clamping jaw supporting seat 8 is fixed on the upper end face of the translation block 6; the jaws 10 are disposed on opposite sides of a pair of jaw supports 8.
in this embodiment, the through groove of installation clamping jaw 10 is set up on clamping jaw supporting seat 8, avoids external force too big for the impact that the jack catch received is too big, damages the jack catch. Further, the clamping jaw 10 is installed in the through groove through the cylindrical pin 9, and the clamping jaw 10 can rotate slightly within a certain angle around the cylindrical pin 9.
In the present embodiment, the front end surface and the rear end surface of the clamping jaw 10 are both parallel to the through groove; the side surface of the clamping jaw 10 comprises a first vertical surface, a second inclined surface, a third clamping surface and a fourth inclined surface which are sequentially connected in the clockwise direction; the third clamping surface is an arc-shaped surface. The third clamping surface is beneficial to the fixation of deep hole processing of the round bar type parts.
In the embodiment, the clamping jaw clamping device further comprises an adjusting screw rod 11, wherein the adjusting screw rod 11 is horizontally arranged on the clamping jaw supporting seat 8; the output end of the adjusting screw 11 is in contact with the fourth inclined surface. The included angle between the fourth inclined plane and the horizontal plane is adjusted by adjusting the screwing-in and screwing-out of the screw rod 11, so that the included angle is changed; the distance between the third clamping surfaces is fine-tuned, namely the clamping position of the same workpiece is fine-tuned.
As shown in fig. 3, when the oil cylinder 2 extends to reach the stroke end to form a loose state, the upper end surface of the top-pull inclined wedge 4 is flush with the upper end of the working cavity; the bottom surface of the upper part of the translation block 6 is contacted with the top-pulling inclined wedge 4; the lower part of the translation block 6 is completely located in the top pull chute 41.
As shown in fig. 4, when the oil cylinder 2 is retracted to reach the stroke end to form a clamping state, the upper end face of the top-pull inclined wedge 4 is positioned in the working cavity; the bottom surface of the upper part of the translation block 6 is separated from the top-pulling inclined wedge 4; the lower portion of the translation block 6 is located within the top pull chute 41. After the clamping state, the oil cylinder 2 does not act, the jacking inclined groove 41 always applies pulling force to the translation block 6, so that the two clamping jaws always apply pressure to the machined workpiece, namely, the machined workpiece is always in the clamping state.
when the device works, the oil cylinder 2 is retracted, the jacking inclined wedge 4 moves downwards along with the output end of the oil cylinder 2, namely a piston, and the device starts to transition from a loosening state to a clamping state: in the process that the top-pull inclined wedge 4 moves downwards, the side face of the top-pull inclined groove 41 generates pressure on the translation blocks 6, the translation blocks 6 move towards each other under the action of the pressure, the distance between the two translation blocks 6 is gradually reduced along with the downward movement of the oil cylinder 2, and when the oil cylinder 2 is retracted to reach a stroke end mode, a clamping state is formed. The invention has similar action principle when the clamping state is transited to the loosening state.
In summary, in the station parallel clamping jaw 10 mechanism provided by the embodiment of the invention, the oil cylinder 2 is used for driving the push-pull inclined wedge 4 to move up and down, that is, the push-pull inclined groove 41 moves up and down along with the push-pull inclined wedge 4, and the translation block 6 moves along the guide block 7 under the action of the push-pull inclined groove 41, so that the actions of loosening and clamping are realized, that is, the workpiece is taken. According to the invention, the loosening and clamping actions are realized only through the mutual matching of the oil cylinder 2, the guide mounting seat 5, the top-pulling inclined wedge 4, the guide block 7 and the translation block 6, and the workpiece is convenient to take, simple in structure, simple to operate and low in cost.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
