Specific embodiment
Specific embodiment of the utility model is further described with reference to the accompanying drawing.
Fig. 1 illustrates a kind of jaw means, this jaw means includes claw main body connection claw pallet 10, the claw support
Disk 10 connects guide rail, and the guide rail includes that upper strata guide rail 4 that is parallel to each other and being linked together and lower floor guide rail 5, the upper layer are led
Rail 4 and the lateral surface of lower floor guide rail 5 are respectively corresponded equipped with upper layer rack 13 and lower layer rack 14, are matched below the lower floor guide rail 5
Close connection support frame 11；In the present embodiment, the guide rail include guide rail bracket 6 top and bottom be respectively equipped with it is parallel to each other
Upper strata guide rail 4 and lower floor guide rail 5 are further fixed on the upper layer rack 13 and corresponding matching of corresponding matching upper strata guide rail 4 on guide rail bracket 6
The lower layer rack 14 of lower floor guide rail 5, support frame as described above 11 connect lower floor guide rail 5 in underside；Specifically, as shown in Figure 1, institute
The double-layer guide rail that guide rail is two guide rails is stated, 10 bottom end of claw pallet is connected with the cunning of at least two cooperation upper strata guide rails 4
Block, generally two or four, sliding block are equipped with sliding slot, and sliding slot cooperation upper strata guide rail 4 can drive claw pallet 10 to slide.
Claw main body includes U-shaped fixed frame 9, and the U-shaped fixed frame 9 is hinged there are two claw, and hinge joint is located at the bottom of close to
It holds but is not end, so two claws are substantially lever, two claw bottom end is articulated with 16 both ends of a lifting shaft, institute
It states and connects 3 output shaft of cylinder below 16 midpoint of lifting shaft, the cylinder 3 is fixedly connected with claw pallet 10；Since cylinder 3 needs
Claw clamp or release is driven while following claw pallet 10 to move together, it requires that the guide rail bracket 6 is for described
The frame that cylinder 3 moves back and forth in it, the bottom end of the U-shaped fixed frame 9 are equipped with the through-hole of cooperation 3 output shaft of cylinder；In this way,
3 output shaft of cylinder moves up and down, and lifting shaft 16 is driven to move up and down, and the claw at 16 both ends of lifting shaft does opening or tightening movement,
The release or clamping to workpiece so can be achieved.
Upper layer rack 13 is connected with the first motor 7 for being fixedly connected with claw pallet 10, and the lower layer rack 14 cooperates
It is connected with the second motor 8 for being fixedly connected with support frame 11, support frame as described above 11 is fixed；In this way, first motor 7 provides power, lead to
It crosses layer rack 13 and imparts power to claw pallet 10, so that claw pallet 10 drives claw main body sliding in upper strata guide rail 4
It is dynamic.Second motor 8 imparts power to 6 entirety of guide rail bracket by lower layer rack 14, and 6 mass motion of guide rail bracket is so as to band simultaneously
Dynamic claw bulk motion greatly accelerates the transport transmission speed of workpiece, simultaneously in this way, claw bulk motion speed is stackable
It can provide Double-stroke, guide rail can spread out recoverable, improve space utilization rate.
First motor 7 and the second motor 8 are servo motor, because servo motor can make to control speed, position precision is non-
It is often accurate, voltage signal can be converted to torque and revolving speed with drive control object.Servo motor rotor revolving speed is believed by input
Number control, and can fast reaction be used as executive component in automatic control system, and have that electromechanical time constant is small, the linearity
The characteristics such as height, pickup voltage, the angular displacement that the electric signal received can be converted on motor reel or angular speed output.Such as
This, realizes signal interaction convenient for this jaw means in automatic control system.
Each claw includes the finger 1 of arcuate stream line type and is connected at least two of 1 inside of finger by hinge 12
2 are padded, the liner 2 on two claw is distributed in mirror image.When the finger 1 of arcuate stream line type can make to clamp workpiece and the patch of workpiece
Conjunction face is bigger, and clamping is more stable, meanwhile, the center of gravity of workpiece can be reduced, 2 material is padded as the metal material of stainless steel, is resistance to
High temperature, high fire-retardance material, because workpiece surface temperature is up to 450~500 DEG C when automotive hub forges and presses, liner 2 can make claw exist
Rigidity is lasting under the condition of high temperature.
It is hinged with a guide rod 17 between lifting shaft 16 and two claw bottoms, so may make claw hinged place articulated shaft
Load is more smooth, and the motion amplitude reduced when claw is opened or tightened increases claw so that clamping workpiece is more steady
Service life.The riser guide 15 that a pair of of cooperation lifting shaft 16 moves is fixedly connected on the inside of the U-shaped fixed frame 9；So make
It is more steady to obtain 16 elevating movement of lifting shaft, meanwhile, so that claw clamping and release are more stable, reliable.
In this way, the obvious beneficial effect of the utility model has:
1. using the form by lower clamping, to space sufficient above workpiece, and can be by the self weight of workpiece by clamping jaw ontology
Itself bears, rather than the situation of upper crawl is born workpiece self weight by finger 1, is increased the service life of claw, is improved and turn
Rate is moved, dynamic stability is increased.
2. double-layer guide rail motion structure provides Double-stroke, space utilization rate is high, and movement velocity is stackable, transporting velocity
Fastly, high-efficient；
3. 1 material of finger of claw is stainless steel material resistant to high temperature, it is lasting to grab rigidity under the condition of high temperature；
4. finger 1 is contacted using symmetric form distribution line, the posture for clamping workpiece can reduce workpiece center of gravity；
5. being suitable for the pattern draft of workpiece by the connection of hinge 12 liner 2 on the inside of finger 1, effectively clamping workpiece.
The present invention is not limited to the above embodiments, using knot identical or approximate with the utility model above-described embodiment
Structure, and other obtained jaw means, it is within the protection scope of the present utility model.
