Description

Mechanical arm

Technical Field

The utility model relates to a mechanical equipment, especially a mechanical force arm.

Background

In general mechanical production equipment, a lot of equipment which does cyclic reciprocating work actions are provided, and generally return stroke is realized by the working equipment, but under the condition that a working part is heavy and return stroke resistance is large, return stroke cannot be realized by the equipment, so that a mechanical force arm which is arranged outside the equipment and can automatically return the working part is needed to meet the requirement.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a mechanical arm of force is provided.

For solving the above-mentioned prior art problem, the utility model discloses a following scheme: the utility model provides a mechanical arm of force, includes frame, fixed axle, axle sleeve, the arm of force, be equipped with the fixed axle in the frame, be equipped with the axle sleeve on the fixed axle, the axle sleeve is fixed with the arm of force, arm of force tip passes through the piston rod connection on universal connector and the pneumatic cylinder, the pneumatic cylinder passes through hinge structure and fixes in the frame, arm of force tip below is equipped with stop screw, stop screw is connected with the pole cover in the frame, the last stop nut that is equipped with of stop screw, stop screw one side just is equipped with the spring between the arm of force and frame.

Preferably, the spring is a tension spring.

Has the advantages that: the utility model adopts the above technical scheme to provide a mechanical arm of force, remedied the not enough of prior art, reasonable in design, convenient operation.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in fig. 1, a mechanical arm of force, including frame 1, fixed axle 2, axle sleeve 3, the arm of force 4, be equipped with fixed axle 2 in the frame 1, be equipped with axle sleeve 3 on the fixed axle 2, axle sleeve 3 is fixed with the arm of

force

4, 4 tip of the arm of force are connected with piston rod 7 on the pneumatic cylinder 6 through universal connector 5, pneumatic cylinder 6 passes through hinge structure 8 to be fixed in

frame

1, 4 tip below of the arm of force are equipped with stop screw 9, stop screw 9 is connected with the rod cover 10 in the frame 1, the last stop nut 11 that is equipped with of stop screw 9, stop screw 9 one side just is equipped with spring 12 between the arm of force 4 and frame 1, spring 12 is tension spring.

During the in-service use, be connected to the arm of force 4 on the working part, start pneumatic cylinder 6 through power device, piston rod 7 on the pneumatic cylinder 6 releases, forms lever structure through fixed axle 2 and the cooperation of the arm of force 4 and pushes away power arm 4, passes to the working part with power on, but the working part atress is limited, consequently the utility model discloses a stop screw 9, stop nut 11 and rod cover 10's cooperation, it is spacing to carry out the working distance of 4 activities of arm of force, prevents that the too much work part atress from leading to damaging, and spring 12 of stop screw 9 one side can be when the arm of force 4 reaches the stroke limit, and pneumatic cylinder 6 stops doing the back, and spring 12's pretension can pull back the initial position with the arm of force 4, realizes the return stroke, to sum up, the utility model discloses simple structure, reasonable in design has higher practicality and novelty, is worth promoting.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
