[0016] The present utility model will be described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments and descriptions of the present utility model are used to explain the present utility model, but not to limit the present utility model.

[0017] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the present utility model provides a floating structure for a polishing machine, which includes a motor fixing seat 12 arranged on the reciprocating motion assembly 11 of the polishing machine. The motor fixing seat can reciprocate on the reciprocating motion assembly, so that the entire floating structure of the present utility model realizes reciprocating motion, ensuring that the polishing wheel can move to any specified position, and improving the polishing efficiency and effect. A vertical linear guide 131 is vertically arranged on the motor fixing seat. A floating plate 132 is vertically arranged on one side of the motor fixing seat. A sliding seat 133 cooperating with the vertical linear guide is arranged on one side of the floating plate. A polishing wheel 134 is arranged on the other side of the floating plate. A driving motor 135 installed on the motor fixing seat drives a horizontally arranged eccentric shaft 136 to rotate. The eccentric shaft drives the floating plate to move. The floating plate drives the polishing wheel to move up and down along the vertical linear guide through the sliding seat, thereby realizing the up and down floating of the polishing wheel and improving the polishing quality.

[0018] Specifically, a bearing 137 is installed on the eccentric circle feature of the eccentric shaft 136. An outer ring of the bearing is fixedly sleeved with a floating block 138. A transverse sliding groove 139 adapted to place the floating block is formed on one side of the floating plate. The floating block driven by the eccentric shaft through the bearing drives the floating plate to move up and down through the transverse sliding groove. During the implementation process, when the driving motor drives the eccentric shaft to rotate, the bearing can ensure that the floating block does not rotate itself but revolves around the driving central axis of the driving motor. At the same time, the transverse sliding groove can ensure the transverse sliding of the floating block. Thus, when the eccentric shaft rotates, the floating block can drive the floating plate to move vertically, that is, the floating plate moves up and down along the vertical linear guide through the sliding seat. It can be seen that this transmission structure is relatively simple and the transmission is stable and reliable.

[0019] The motor fixing seat 12 of the present utility model includes a bottom plate 120, a vertically arranged mounting plate 121 connected to the bottom plate, and fixing frames 122 arranged at both ends of the mounting plate and connected to the bottom plate. The driving motor is installed in the installation space 123 formed by the bottom plate, the mounting plate and the two fixing frames. The vertical linear guide is arranged on the mounting plate. The structure of this motor fixing seat has good rigidity, is simple, practical, and has low cost. The installation space with openings on both sides not only has a large space, the driving motor can be directly fixed on the base, and the installation is convenient; moreover, it can reduce the pollution of dust and waste chips. Preferably, two vertical linear guides are arranged on the mounting plate, and one end of each of the two vertical linear guides can abut against the bottom plate to ensure that the vertical linear guide is more stable. Two sliding seats are arranged in cooperation with each vertical linear guide, and each sliding seat is fastened to the floating plate by screws. Thus, through the cooperation of the linear guide and the sliding seat, it can be ensured that the floating plate of the load moves smoothly without causing deviation or falling off; and the design of two linear guides and four sliding seats further improves the stability and reliability of the transmission.

[0020] The drive motor of the present utility model is connected to a speed reducer 124 arranged in the installation space to drive the speed reducer to drive the eccentric shaft to move, which is beneficial to controlling the rotation speed of the eccentric shaft. Specifically, the output shaft 125 of the speed reducer passes through the mounting plate and is connected to the eccentric shaft. A through hole 1210 is formed in the mounting plate for the output shaft to pass through, and the through hole can install and fix the speed reducer, further improving the smoothness of transmission. At the same time, the protruding eccentric shaft facilitates the installation of bearings and floating blocks. During implementation, a shaft pin 1360 is arranged on the eccentric shaft to fix the inner ring of the bearing, further improving the convenience of installation.

[0021] Preferably, a fixed support frame 126 is provided on the other side of the floating plate, and the polishing wheel is installed on the fixed support frame, so that the floating plate drives the polishing wheel to move up and down through the fixed support frame. Specifically, the polishing wheel is driven to rotate by a vertically arranged polishing shaft 127, and the polishing shaft is driven to rotate by a polishing motor 128 installed on the floating plate. Thus, when the polishing wheel rotates, the polishing motor, the polishing shaft and the polishing wheel can move up and down integrally to achieve floating polishing. During implementation, the polishing shaft is connected to the polishing motor through a synchronous pulley 129 to improve the smoothness of transmission, and the polishing shaft is installed in a bearing sleeve 130, and the bearing sleeve is fixed on the fixed support frame, which is not only beneficial to firm installation, but also can avoid damaging the polishing shaft.
