The first embodiment is as follows:
a high-efficiency periphery polishing machine is shown in figures 1 and 2 and comprises a frame, a workpiece clamping device and a polishing brush device, wherein the workpiece clamping device and the polishing brush device are installed on the frame. The workpiece clamping device is positioned below the rack, and the polishing hairbrush device is positioned above the rack. The machine can polish a plurality of sheet-shaped workpieces, and can take a glass screen as an example. Of course, other sheet-like workpieces are also possible. The difference of processing the workpieces is that a plurality of workpieces can be stacked, a plurality of workpieces can be processed at one time, and the stacking mode and the position arrangement can be further understood by referring to the figure 1.
As will be understood from fig. 5, the workpiece clamping device includes a square clamping housing, a side supporting mechanism, a side abutting mechanism, and a lower supporting mechanism. The stacked workpieces stand on the lower support mechanism to be placed. The side supporting mechanisms positioned on the two sides of the clamping shell limit or keep away from the edge of the laminated workpiece. The side jacking mechanism jacks and rotates the side surface of the stacked workpiece. The lower support mechanism supports or moves away the lower edge of the stacked workpieces. The laminated workpieces are placed on the lower supporting mechanism firstly, and are limited and sorted through the lower supporting mechanism, the side supporting mechanism and the side jacking mechanism, so that a group of edges to be polished of the laminated workpieces are reserved towards the polishing brush device.
The polishing brush device comprises a two-axis driving mechanism, a moving seat, a brush disc and a brush driving mechanism. The two-axis driving mechanism is connected with the moving seat and drives the moving seat to be randomly positioned and move on an X axis and a Z axis, and the brush driving mechanism is assembled on the moving seat and drives the brush disc to rotate. The two-axis driving mechanism is composed of a screw rod driving mechanism and can drive in the X axis and the Z axis.
As can be seen in fig. 1 and 4, the back surface of the brush plate is provided with a liquid tank for storing polishing liquid, the bottom of the liquid tank is provided with a liquid outlet hole, and the bottom surface of the brush plate is provided with a replaceable polishing brush.
In fig. 5 it can be seen that the bottom of the clamping shell is provided with a Y-axis drive mechanism which drives the clamping shell to move back and forth with a stroke in the Y-axis direction.
In the scheme, the movement in the three-axis direction is realized through a screw rod transmission mode. For other moving means, the modes of cylinder expansion and contraction, hydraulic cylinder driving and the like can also be adopted.
The working process is as follows: firstly, an operator puts a stacked workpiece into a clamping shell, at the moment, the lower part of the stacked workpiece is supported, then the stacked workpiece is driven by stretching and contracting in the Y-axis direction, a side supporting mechanism is used for arranging and flattening the side surface of the stacked workpiece, then the X-axis of the stacked workpiece is flattened by a side jacking mechanism, the position of the stacked workpiece can be kept limited at the moment, then the upper surface, namely the upper edge of the stacked workpiece, is reserved, a polishing brush device starts to work, falls to the processing position of the stacked workpiece, then moves back and forth in the X-axis direction and is washed and showered along with the continuous injection of polishing liquid, and during the polishing process, a Y-axis driving mechanism positioned below the clamping shell can be driven to drive the clamping shell to move back in the Y-axis direction. After the edge machining is finished, the edge is reset completely, only the side jacking mechanism is reserved for clamping the laminated workpiece, the rotation is finished, the edge changing is realized, and the subsequent machining is carried out. The subsequent processing process is as above, wherein the supporting and limiting of the plurality of side surfaces are carried out, and then the polished edge surface to be processed is left, and the processing steps are continuously completed.
With reference to fig. 6, it should be noted that, in the present embodiment, after the first edge processing is completed, when the edge is changed, the processed edge is taken as the bottom edge, that is, the edge is rotated by 180 degrees to process the opposite edge. The sides are then reworked. According to the scheme, the workpiece with the rectangular structure is taken as an example, so that after the first edge of the rectangular workpiece is polished, the workpiece is rotated by 180 degrees, the first edge is positioned below and attached to the lower supporting mechanism, the edge after machining is used for positioning, and the polished edge can be kept smooth and the consistency of products can be kept.
A schematic view of the processing state of the product in which the workpiece has burrs and burrs is understood in conjunction with fig. 6, and the processing is performed by installing the product as described in fig. 6 until the four edges of the product are finished.
It can be seen from this that: the workpieces are stacked in an accumulated manner, the consistency of products is guaranteed, the machining efficiency is greatly improved, the products can be limited and tidy in machining through positioning and arranging of four side surfaces and supporting of the lower portion, then the polishing brush device performs polishing operation, the automation degree is high, manpower is reduced, edge changing operation and 360-degree rotation can be achieved to drive the products to change edges automatically together, and the machining efficiency is greatly improved; the productivity is improved. The integration of the working platform and the transmission device ensures the flatness of the equipment, also ensures the uniformity of cutting force and improves the efficiency. The liquid tank is automatically utilized to provide the polishing liquid, and the polishing quality is improved. During polishing work, the workpiece can move on the Y axis back and forth, the polishing brush device can also move in the X axis direction and is synchronously carried out, polishing one-way traces can be overcome, polishing traces are eliminated, and product quality is improved.

Before polishing, the intelligent control module receives stress data fed back by the stress sensor to determine polishing pressure, when the detected stress data is in a preset stress position, the intelligent control module determines that the pressing pressure of the polishing brush device is preset pressure, and if the detected stress data does not fall into a preset range, the pressing pressure of the polishing brush device is adjusted according to the difference between the preset stress range data and the detected stress data.
After the downforce of the polishing brush device is determined, the intelligent control module adjusts the downforce pressure of the polishing brush device according to the difference between the thickness data fed back by the ultrasonic thickness measuring sensor and the preset thickness, if the thickness difference data are within the preset range, the downforce pressure of the polishing brush device is not adjusted, and if the thickness difference data are not within the preset range, the downforce pressure of the polishing brush device is adjusted differently according to different ranges of the thickness difference.

Furthermore, when the intelligent control module receives the stress data detected by the stress sensor to control the pressure of the polishing brush device, the detected stress data is set as Y s Setting the preset stress data as Y 0 Setting the preset pressure of the polishing brush device to W 0 The maximum pressure of the polishing brush device is set to W max ，1.4*W 0 ＜W max ；
If Y is s ≤Y 0 The intelligent control unit determines W 1 ＝W 0 ；
