Problems solved by technology

[0003] Because traditional pneumatic clamping cannot adjust the spacing of the jaws, when producing different types of workpieces, due to the size change of the workpieces, it is necessary to replace the jaws as a whole to adapt to its clamping action. In this way, the efficiency of type change Low, and the repeated positioning accuracy is affected after replacement

Embodiment 1

[0037] like Figure 1-8, a grabbing mechanism that can quickly adjust the position of the jaws, it includes a base body 1, the interior of the base body 1 is processed with a through chute, on the chute is installed a symmetrically reversed arrangement of the first sliding slant through sliding fit Block 5 and the second sliding block 8; the first sliding block 5 and the second sliding block 8 are matched with a power mechanism for driving both clamping and reverse release along the chute; The end face of the first sliding slant block 5 is connected with a first adjusting screw 10, and the end face of the second sliding slanting block 8 is connected with a second adjusting screw 19; The first slide block 11 is installed in transmission cooperation, and the second slide block 18 is installed on the second adjusting screw rod 19 through the left-hand thread transmission cooperation; the first slide block 11 is fixedly installed with the The first jaw 14, the second slider 18 is...

Embodiment 2

[0048] The use method of any one of the grasping mechanisms that can quickly adjust the position of the jaws is characterized in that:

[0049] Loosening and clamping action: After the hydraulic cylinder 23 receives the signal, the piston rod descends, and the ejector rod 3 is pressed down for a certain distance, and at the same time, the guide slant block 2 also moves downward for the same distance, passing through the left and right slopes 27 of the guide slant block 2 , apply opposite forces to the first sliding block 5 and the second sliding block 8 respectively, thereby driving the first adjusting screw 10 and the second adjusting screw 19 to separate, passing through the first sliding block 11 and the second right sliding block 18, The first jaw mounting base 12 and the second jaw mounting base 17 realize the separation of the first jaw 14 and the second jaw 15, thereby releasing the workpiece;

[0050] On the contrary, when the hydraulic oil cylinder 23 receives the sig...

Abstract

The invention relates to a grabbing mechanism capable of quickly adjusting the positions of clamping jaws and a using method thereof. A chute penetrates through a base body; a first sliding inclined block and a second sliding inclined block are symmetrically and reversely arranged and are arranged on the chute in a sliding fit mode; the end face of the first sliding inclined block is in fit connection with a first adjusting screw; the end face of the second sliding inclined block is in fit connection with a second adjusting screw; a first sliding block is arranged on the first adjusting screwin a transmission fit mode through a right-hand thread; a second sliding block is arranged on the second adjusting screw in a transmission fit mode through a left-hand thread; a first clamping jaw isfixedly arranged on the first sliding block through a first clamping jaw mounting seat; a second clamping jaw is fixedly arranged on the second sliding block through a second clamping jaw mounting seat; and the first adjusting screw rod and the second adjusting screw rod match and are connected through an internal spline sleeve. According to the grabbing mechanism, the manipulator claws are rapidly adjustable clamping claws, so that the shape changing efficiency of the claws is greatly improved, and the repeated positioning precision is guaranteed.

Description

technical field [0001] The invention belongs to the field of manipulators, and in particular relates to a grasping mechanism capable of quickly adjusting the position of claws and a use method thereof. Background technique [0002] In various mechanical processing fields such as automobile gearboxes, wind power, aerospace, etc., high-efficiency and high-speed automatic loading and unloading complete sets of equipment have become the target of choice for various enterprises. The end clamping and releasing mechanism of automatic loading and unloading is useful either pneumatically or oil-driven. Pneumatic clamping and releasing technology has been blocked by the technology of foreign imported clamping system manufacturers, and the price of the clamping system is very expensive. There are also very few domestic manufacturers of oil-operated clamping systems, and they are basically made by themselves, and the clamping reliability needs to be verified. [0003] Because traditio...
