Clamping device and system, control method and bar clamping and conveying method

Abstract

The invention relates to the field of machining, in particular to a clamping device and system, a control method and a bar clamping and conveying method. According to the clamping device, when a boosting rod is driven by a driving piece to move in the first direction, a first pressing roller support is driven to move in the first direction, and a transmission assembly drives a second pressing roller support to move in the opposite direction, so that the first pressing roller support and the second pressing roller support get close to each other to reduce a clamping space or get away from each other to expand the clamping space; an adjusting mechanism elastically acts on the driving piece and the boosting rod in the axial direction so that a connecting gap can be eliminated, precision is guaranteed, and accumulative errors are avoided; and the first pressing roller support is connected to the boosting rod in a floating mode such that a large displacement floating compensation function can be achieved, the problem of deviation such as vertical shaking in the workpiece conveying process is solved, and it is guaranteed that the axes of clamped bars and the center of a rotating cutter wheel are always kept consistent in the machining process such that the product quality problems that in the cutting process of the surfaces of the bars, the cutting thicknesses are different or some bars are not cut off and the like can be solved.

Description

technical field [0001] The present application relates to the field of processing, in particular, to a clamping device, a system and a control method, and a clamping and conveying method for bars. Background technique [0002] During the peeling and chipping process of the bar, a layer of skin parallel to the axis of the bar is usually cut off by rotating the cutter wheel along the diameter of the bar. [0003] At present, the above operations are generally completed by moving the bar through a fixed rotating cutter wheel, that is to say, the bar is first fixed by the clamping device, and then the bar and the clamping device are sent to the rotating cutter wheel by the transfer mechanism. Make chips. In order to ensure that the axis of the bar and the center of the cutter wheel are always consistent during the pinching process, the existing clamping mechanism generally uses two push rods to clamp the bar from two directions, but the movement of the two push rods cannot Kee...

Problems solved by technology

In order to ensure that the axis of the bar and the center of the cutter wheel are always consistent during the pinching process, the existing clamping mechanism generally uses two push rods to clamp the bar from two directions, but the movement of the two push rods cannot Always keep synchronous, and at the same time, after the push rod has been used for a long time, the movement synchronization will also have errors, which makes the axis of the bar deviate from the center of the rotating cutter wheel, and it is easy to cause chip thickness to vary or have irregularities on the surface of the bar during the chip cutting process. If the bar is not cut off, and the bar after being chipped is prone to ellipse, it will cause product quality problems, and it will also affect the service life of the rotary cutter wheel, resulting in an increase in the use and maintenance costs of the peeling equipment.
