Description

Linkage double-acting mechanical gripper device
Technical Field
The invention relates to a linkage double-acting mechanical gripper device, and belongs to the field of forging machinery.
Background
The forging post workers have high labor intensity, high temperature, high heat, dust resistance and poor working environment, so that more and more enterprises face difficulty in job recruitment and low production efficiency, more and more forging enterprises tend to use mechanical arms or forging robots to replace manual work, or the labor intensity of the workers is reduced, the efficiency is improved, and the cost is saved. The existing manipulator is single in functional structure, and for saving equipment cost, under the condition that one forging equipment is matched with one forging robot, the robot gripper is required to grab bars and place the bars into a forging die, and grab forged forgings, so that the economic benefit is higher.
Disclosure of Invention
In order to solve the problem, the utility model provides a two effect machinery tongs devices of linkage.
The technical scheme of the invention is as follows:
a linkage double-acting mechanical gripper device comprises a bottom plate, wherein a double-acting oil cylinder is fixedly arranged on the upper side of the bottom plate, the output end of the double-acting oil cylinder is connected with a slide block rack, and gears are respectively connected to two sides of the slide block rack; the gear is connected with the crank arm through a connecting rod; one end of the crank arm is connected with the clamping assembly, and the other end of the crank arm is connected with the auxiliary connecting rod through a pin; the other end of the auxiliary connecting rod is connected to the bottom plate through a pin;
the clamping assembly comprises symmetrically arranged connecting plates, and V-shaped blocks are arranged on the connecting plates; the lower side of the connecting plate is connected with an inverted L-shaped second connecting plate; the second connecting plate is provided with a V-shaped supporting plate.
Clamping a bar stock through a V-shaped block; the flange of the formed forging piece can be clamped by the V-shaped supporting plate, and the placement of the bar stock and the taking out of the formed forging piece are completed by one device; the diameter of the object to be clamped can be adjusted by adjusting the lengths of the connecting rod and the crank arm according to the requirement.
Preferably, the distance between the V-shaped blocks is smaller than that between the V-shaped supporting plates.
Because the bar is cylindric, the diameter of shaping forging is greater than the bar, and the distance between the V type piece is less than the distance between the V type layer board, can guarantee that bar and shaping forging all can press from both sides and get.
Preferably, a groove is formed in the bottom plate, and the rack is arranged in the groove.
The rack is arranged in the groove and slides in the groove, so that the position is ensured not to deviate.
Further preferably, a sliding limit pin penetrates through the rack.
The limiting pin can ensure that the moving distance of the rack is within a set range.
Preferably, the crank arm is an arc-shaped plate.
Preferably, the crank arm is connected with the connecting rod through a pin.
The invention has the beneficial effects that:
the V-shaped blocks and the V-shaped supporting plates are arranged at the same time, and the distance between the V-shaped blocks is smaller than that between the V-shaped supporting plates, so that the bars can be clamped by the V-shaped blocks without replacement; and the formed forging piece can be clamped by the V-shaped supporting plate.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the internal structure of the present invention;
FIG. 3 is a schematic structural view of the clamping of the formed forging of the present invention;
1. a double-acting oil cylinder; 2. a rack; 3. an auxiliary link; 4. a connecting rod; 5. a crank arm; 6. a V-shaped block; 7. a V-shaped supporting plate; 8. a gear; 9. a connecting plate; 10. a second connecting plate; 11. forming a forged piece; 12. a base plate.
Detailed Description
The present invention will be further described by way of examples, but not limited thereto, with reference to the accompanying drawings.
Example 1:
a linkage double-acting mechanical gripper device comprises a bottom plate, wherein a double-acting oil cylinder is fixedly arranged on the upper side of the bottom plate, the output end of the double-acting oil cylinder is connected with a slide block rack, and gears are respectively connected to two sides of the slide block rack; the gear is connected with the crank arm through a connecting rod; the gear is fixedly connected with the connecting rod through a central connecting shaft, and the connecting lever is an arc-shaped plate and is in pin connection with the connecting rod. One end of the crank arm is connected with the clamping assembly, and the other end of the crank arm is connected with the auxiliary connecting rod through a pin; the other end of the auxiliary connecting rod is connected to the bottom plate through a pin; the clamping assembly comprises symmetrically arranged connecting plates, and V-shaped blocks are arranged on the connecting plates; the lower side of the connecting plate is connected with an inverted L-shaped second connecting plate; a V-shaped supporting plate is arranged on the second connecting plate; clamping a bar stock through a V-shaped block; the flange of the formed forging piece can be clamped by the V-shaped supporting plate, and the placement of the bar stock and the taking out of the formed forging piece are completed by one device; the clamping device can be adjusted by adjusting the lengths of the connecting rod and the connecting lever according to the diameter of an object to be clamped, and the distance between the V-shaped blocks is smaller than that between the V-shaped supporting plates. Because the bar is cylindric, the diameter of shaping forging is greater than the bar, and the distance between the V type piece is less than the distance between the V type layer board, can guarantee that bar and shaping forging all can press from both sides and get. The bottom plate is provided with a groove, and the rack is arranged in the groove; the rack is arranged in the groove and slides in the groove, so that the position is ensured not to deviate.
The working principle is as follows: the oil cylinder drives the rack to retreat to drive the V-shaped block to clamp the heated bar, the rack advances to place the bar on a working part after reaching a designated position, and the rack retreats to drive the V-shaped supporting plate to clamp the flash of the formed forged piece after forging and pressing, so that the forged piece is taken out.
Example 2:
a linkage double-acting mechanical gripper, the structure of which is the same as that of embodiment 1, except that: a sliding limiting pin penetrates through the rack; the limiting pin can ensure that the moving distance of the rack is within a set range.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and all equivalent structures or equivalent flow transformations made by using the contents of the present specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
