Portable automatic clamping and rotating mechanism

Abstract

This utility model discloses a convenient automatic clamping and rotating mechanism, including a clamping platform connected to a quick-change disc, a linear sliding assembly, clamping arms symmetrically arranged on the left and right, a clamping cylinder, a push-rotating assembly, and a rotating clamping block. The lower end face of the clamping platform is provided with a linear sliding assembly, which includes a slider rail assembly symmetrically arranged at the front and rear centers, a sliding plate, and a limiting block for limiting the sliding displacement. The push-rotating assembly includes a push-cylinder, a mounting base, gears and racks that mesh with each other, and a rotating platform coaxially connected to the gears. This mechanism uses the push-rotating assembly to accurately achieve stable control of the rotation angle, and uses the push-cylinder with a non-high-pressure supply to push the rack. By changing the transmission ratio, the gears are driven to rotate in a low-torque manner, thereby controlling the rotation of the rotating platform and the rotating clamping block. Compared with traditional rotating cylinders, the push-rotating assembly, combined with a high-pressure exhaust structure assembly, significantly reduces the space occupied.

Description

Technical Field

[0001] This utility model relates to the field of automation equipment, specifically to a convenient automatic clamping and rotating mechanism. Background Technology

[0002] In advanced manufacturing and intelligent manufacturing, automated equipment is widely used. To accelerate production pace, increase efficiency, and maintain product consistency, automated operations effectively meet these technical requirements. The automation requirements for material handling and transfer are particularly numerous, including actions such as gripping, transporting, and flipping. Since many workstations on automated production lines occupy significant space, each mechanism in the automated assembly process needs to be streamlined to free up more usable space. This requires improving the design structure of existing automated transfer equipment to reduce its footprint while ensuring that automated material gripping, transporting, and flipping are not affected. Furthermore, when greater rotational power is required, existing rotary cylinders rely on significant air pressure to rotate and maintain sufficient rotation angle and accuracy. Therefore, it is necessary to design streamlined and practical automated transfer equipment. Utility Model Content

[0003] The purpose of this invention is to simplify the size of each module in the automated assembly to reduce space occupation while ensuring that the automatic clamping, handling, and flipping of materials are not affected. Furthermore, it abandons the traditional rotary cylinder solution that requires high-pressure air to maintain rotation. Instead, it designs an automatic detection device to reduce the space occupied by the flipping mechanism after clamping. It utilizes a push-rotation component to precisely control the stable rotation angle and a push-rotation cylinder with a non-high-pressure air supply to push the rack. By changing the transmission ratio, it can drive the gears to rotate with low torque, thereby controlling the rotation of the rotary table and the rotary clamping block. This design is practical and convenient.

[0004] The technical solution adopted to solve the above problems is:

[0005] A convenient automatic clamping and rotating mechanism includes a clamping table connected to a quick-change plate, a linear sliding assembly, clamping arms arranged symmetrically on the left and right sides, a clamping cylinder, a push-rotating assembly connected to the clamping arms, and a rotating clamping block.

[0006] The lower end face of the clamping platform is provided with a linear sliding assembly, which includes a slider rail assembly, a sliding plate, and a limiting block for limiting the sliding displacement, all arranged symmetrically at the front and rear centers. The slider of the slider rail assembly is connected to the sliding plate, and the sliding plate is connected to the clamping arm, which is arranged perpendicularly to the rail. The two sets of sliders move in parallel or opposite directions. A clamping cylinder is provided between the two clamping arms to drive the two clamping arms to move under force.

[0007] The push-rotating assembly is located inside the clamping arms on both sides and includes a push-cylinder, a mounting base, gears and racks that mesh and drive each other, and a rotary table coaxially connected to the gears. The rotary table is connected to a rotating clamping block. The push-cylinder is connected to the rack in parallel through a connecting block. The meshing relationship between the rack and the gear is maintained and limited by the mounting base. The mounting base is connected to the clamping arms. A bearing perpendicular to the inner side of the clamping arm is provided at the center of the mounting base. The bearing is fitted with a rotating shaft, which is fitted with the keyway of the gear. The inner side of the rotating shaft is fitted with the rotary table.

[0008] Furthermore, the limiting block includes an inner limiting block and an outer limiting block to limit the inward or outward displacement of the sliding plate, and a buffer is provided at the contact point between the sliding plate and the inner limiting block or the sliding plate and the outer limiting block.

[0009] Furthermore, a directional guide rod is provided between the connecting block and the mounting base, and the directional guide rod cooperates with the directional sliding groove provided on the mounting base to assist the linear sliding movement of the push rod of the push cylinder.

[0010] Furthermore, the mounting base is provided with a starting angle limiting plate and an ending angle limiting plate on the outer side of the cylindrical rotating table. The two angle limiting plates are provided with limiting pins in the tangential direction with the outer wall of the rotating table. The limiting pins alternately engage with the stop blocks provided on the outer wall of the rotating table to limit the starting and ending angles of the gear being pulled and driven to rotate by the rack.

[0011] Furthermore, the push cylinder is securely connected to the clamping arm to ensure the stability and reliability of the push rotation assembly structure.

[0012] The beneficial effects of this utility model are:

[0013] This convenient automatic clamping and rotating mechanism uses a push-rotating component to precisely control the rotation angle and uses a push-rotating cylinder with a non-high-pressure air supply to push the rack. By changing the transmission ratio, the gear is driven to rotate in a low-torque manner, thereby controlling the rotation of the rotary table and the rotating clamping block. Compared with traditional rotary cylinders, the push-rotating component, along with the high-pressure air exhaust structure assembly, significantly reduces the space occupied, making it practical and convenient.
