Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing, and specifically relates to an automatic processing fixture for automotive parts. Background Technology

[0002] In the existing technology, when automotive parts are processed by machine tools, manual loading and unloading is required. There is a lack of automated equipment to automatically send the workpieces to the machine tool for machining. Furthermore, when the automotive parts are finished, manual unloading is still required. This not only poses a risk of arm injury to the workers, but also results in low efficiency for manual loading and unloading, which affects the machining efficiency of automotive parts. Utility Model Content

[0003] The purpose of this invention is to provide an automatic machining fixture for automotive parts, which can automatically load and unload materials for machine tools and improve the machining efficiency of automotive parts.

[0004] The purpose of this utility model is achieved as follows: an automatic machining fixture for automotive parts includes a machine body, a clamping mechanism and a machining mechanism on the machine body, and a gantry frame corresponding to the clamping mechanism and machining mechanism on the machine body. The frame includes a fixed beam, and vertical support legs are provided on the lower sides of both ends of the fixed beam. The two support legs are symmetrically distributed on the left and right sides of the machine body. A sliding seat that can move along the length direction is provided on the fixed beam, and a mounting frame is provided on the sliding seat. A gripping mechanism is provided on the lower side of the mounting frame.

[0005] In operation, this invention involves a robotic arm placing the automotive part to be processed between the three-jaw chuck and the clamping head of the clamping mechanism. As the automotive part rotates, a cutting tool on the tool holder performs machining on it. After machining, the cutting tool separates from the automotive part, and the robotic arm grasps the part. The three-jaw chuck and clamping head then separate, and the robotic arm delivers the automotive part to the side of the machine tool, removing the finished workpiece. Compared with existing technologies, the advantages of this invention are: it enables automatic loading and unloading of materials for the machine tool, improves the processing efficiency of automotive parts, eliminates manual loading and unloading, has a high degree of automation, and is safer.

[0006] As a further improvement of this utility model, the clamping mechanism includes a first support and a second support. A rotatable three-jaw chuck is provided on the first support, and a clamping head is provided on the second support. The three-jaw chuck and the clamping head are correspondingly arranged. The automotive parts are clamped by the three-jaw chuck and the clamping head.

[0007] As a further improvement of this utility model, the machining mechanism includes a movable base, a plurality of transverse guide rails are provided on the machine tool body, the movable base is movably connected to each guide rail, a plurality of longitudinal guide rails are provided on the movable base, a movable base is movably connected to the guide rails, and a tool holder for mounting a lathe tool is provided on the movable base. A set of lead screw mechanisms is provided on the machine tool body corresponding to the movable base and the movable base, respectively, to drive the movable base to move.

[0008] As a further improvement of this utility model, the fixed beam is arranged along the width direction of the machine tool body, and two guide rails are arranged along the length direction on the fixed beam. The sliding seat is movably connected to the two guide rails via two sliders. Two symmetrical supports are arranged on the fixed beam, and a lead screw is rotatably arranged between the two supports. The lead screw is located below the sliding seat, one end of the lead screw is driven by a reduction motor, and the lead screw nut is driven by the sliding seat. When the lead screw rotates, it drives the sliding seat to move through the lead screw nut, and the robotic arm can move back and forth.

[0009] As a further improvement of this utility model, the mounting bracket includes two L-shaped fixing plates arranged on the left and right sides of the sliding seat, and a horizontal plate is provided between the bottom of the two fixing plates.

[0010] As a further improvement of this utility model, the gripping mechanism includes a screw jack disposed on the underside of the base plate. A vertical mechanical arm is provided at the lifting end of the screw jack, and a robotic hand is provided at the lower end of the mechanical arm.
