Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical clamps and relates to a mechanical clamp driven by a steering gear. Background Art

[0002] In the manufacturing process, mechanical grippers are used to pick up and place workpieces to improve efficiency and save labor. These grippers mimic certain movements of the human hand and arm, automatically grasping and moving objects or manipulating tools according to a fixed program. Existing mechanical grippers often use pneumatic or hydraulic cylinders as a driving force, leveraging the cylinder's expansion and contraction to drive the jaws' swing to clamp and release the workpiece. Current mechanical grippers used in manufacturing suffer from complex structures and poor stability. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a mechanical clamp driven by a steering gear, which uses the steering gear as the driving force to drive the clamp to move. The two clamps move closer or farther away along the linear guide rail, thereby achieving smooth and reliable operation of the clamp.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a mechanical clamp driven by a servo, comprising a support base, a servo, and a clamping member, characterized in that the servo is fixed to the back of the support base, a guide rail bracket is fixed to the front of the support base, a steering wheel is fixed to the output shaft of the servo, a ferry disk is fixed to the outer side of the steering wheel through a stud, two parallel linear guide rails are fixed on the guide rail bracket, the clamping member comprises two clamping jaws, a clamping jaw and a slider, the clamping jaw is fixed to the front end of the clamping jaw seat, two sliders are fixed to the rear end of the clamping jaw seat, the two sliders are respectively engaged with and slidably matched with the two linear guide rails, the tail of the clamping jaw seat has a protruding connecting part, and a swing arm is hinged between the connecting part of the ferry disk and the clamping jaw seat.

[0005] Furthermore, both ends of the guide rail bracket are provided with embedding grooves, and both ends of the linear guide rail are embedded in the embedding grooves and fixed by stud two.

[0006] Furthermore, the swing arm is arc-shaped, the ferry plate is diamond-shaped, the inner end of the swing arm is rotatably connected to one end of the ferry plate through a step stud, and the outer end of the swing arm is rotatably connected to the connecting part through a step stud.

[0007] Furthermore, a hollow clamping hole is provided on the clamping surface of the clamping claw, so that the goods can be clamped more easily.

[0008] Furthermore, a dovetail groove is provided at the front end of the clamping jaw seat, and the clamping jaw has a trapezoidal bar embedded in the dovetail groove. Aligned connecting holes are provided on the clamping jaw seat and the trapezoidal bar, and bolts are inserted into the connecting holes to fix the trapezoidal bar.

[0009] This servo-driven mechanical gripper generates rotational power from the servo, driving the steering wheel and ferry disc. The ferry disc and swing arm convert this rotational angle into linear motion, driving two sliders mounted on linear guides in reciprocating linear motion. The sliders then drive the gripper's fixed jaw base and the jaws together, opening and closing the gripper. This servo-driven mechanical gripper features a simple structure, reliable motion, good operational stability, and economical operation. Furthermore, the gripper can be replaced to suit different scenarios, and its dovetail mounting structure provides enhanced stability and reliability.

[0010] Compared with the existing technology, this servo-driven mechanical gripper has the following advantages:

[0011] 1. Use the servo as the driving force to drive the gripper to move.

[0012] 2. Double linear guide structure to ensure smooth and reliable operation of the gripper.

[0013] 3. The gripper and gripper base can be quickly separated, which can be used for quick replacement of grippers to adapt to different scenarios.

[0014] 4. The linear guide rail is embedded in the groove of the guide rail bracket to prevent damage caused by scratches and protect the linear guide rail well. BRIEF DESCRIPTION OF THE DRAWINGS
