Workpiece roundness on-line detection device for turning center

Abstract

This utility model relates to the field of workpiece roundness detection technology, specifically to an online workpiece roundness detection device for a turning center. It includes a base, a processing and detection mechanism mounted on the top of the base, a turning machine mounted on the top of the base, and a roundness detector mounted on the top of the base. The processing and detection mechanism includes an operating table, which is fixedly connected to the top of the base. A gear ring is rotatably connected to the front of the inner wall of the operating table via a bearing. In this utility model, a motor drives a first rotating rod to rotate clockwise, which, through a ratchet and a second rotating block, squeezes a first hydraulic rod, increasing the internal pressure of the hydraulic system and driving a second hydraulic rod to move backward. This allows the clamping blocks to move towards each other and clamp the workpiece. When the motor reverses direction, a ratchet, pawl, collar, and pulley assembly drives a second rotating rod and a circular gear to rotate, which in turn drives the gear ring and a fixed plate to rotate, causing the workpiece to rotate to the bottom of the roundness detector for detection.

Description

Technical Field

[0001] This utility model relates to the field of workpiece roundness detection technology, specifically to an online workpiece roundness detection device for turning centers. Background Technology

[0002] Turning refers to the process of machining a workpiece using a lathe (a type of machine tool). During turning, the workpiece is fixed on the spindle of the lathe and rotates at high speed, while the cutting tool (a type of cutting tool) moves along the surface of the workpiece, removing excess material through cutting action, thereby achieving the machining of the workpiece's shape, size, and surface quality.

[0003] Traditional roundness inspection is usually done offline, which requires removing the workpiece from the turning center and then measuring it with a special roundness inspection instrument. This not only increases the workpiece loading and unloading time but also reduces production efficiency.

[0004] Therefore, an online workpiece roundness detection device for turning centers is proposed to solve the problems mentioned above. Utility Model Content

The motor drives the first rotating rod to rotate clockwise, which, through the ratchet and the second rotating block, squeezes the first hydraulic rod, increasing the internal pressure of the hydraulic system, and drives the second hydraulic rod to move backward, so that the clamping blocks move towards each other to clamp the workpiece. When the motor reverses, it drives the second rotating rod and the spur gear to rotate through the ratchet, pawl, collar and pulley assembly, which in turn drives the gear ring and the fixed plate to rotate, so that the workpiece rotates to the bottom of the roundness detector for inspection.

[0014] Second, the automated clamping, processing and inspection process significantly improves processing efficiency, reduces manual operation time, reduces the need for manual intervention, and reduces the labor intensity of operators. Attached Figure Description
