The polishing between the polishing wheel 13 and the workpiece is performed, at this time, the diameter of the polishing wheel 13 is reduced due to friction, at this time, the diameter of the polishing wheel 13 is reduced slightly, but sufficient polishing of the workpiece cannot be satisfied, at this time, the change of the value of the polishing wheel 13 is small, accurate movement of the polishing wheel 13 cannot be realized by moving the cantilever 12, further, the movement of the transmission assembly 35 is realized by adjusting the length of the telescopic rod 34, further, the transmission assembly 35 moves in the sliding groove 312, and further, the diameter compensation of the polishing wheel 13 is realized by moving the sliding groove 312, so that normal performance of polishing of the workpiece is maintained, and the difference is compensated by measuring the workpiece by a worker in the process of identifying whether the polishing of the workpiece is completed.
After the loss of the polishing wheel 13 increases, the position of the abutting piece 15 is adjusted through the gear rack set 162, so that the abutting piece 15 is abutted against the cantilever 12, the position of the cantilever 12 is moved through the movement of the abutting piece 15, the position adjustment of the polishing wheel 13 is completed, meanwhile, in order to avoid the position of the cantilever 12 from shifting after adjustment, the abutting wheel 21 is driven to abut against the cantilever 12 by the air cylinder 222, the constraint of the cantilever 12 and the polishing wheel 13 is achieved, and then the workpiece is processed.
Through the transmission component 35 and the connecting rod 19 that set up, can realize carrying out polishing to the work piece of equidimension not, simultaneously take place wearing and tearing at the polishing wheel 13 and can't satisfy the polishing demand after, accomplish the compensation to the wearing and tearing part of polishing wheel 13 through transmission component 35, and when polishing wheel 13 continuously wearing and tearing the back, adjust the position of cantilever 12 again to this reduces the adjustment number of times to cantilever 12 in the polishing process, when improving polishing efficiency, also can realize the polishing machine and polish the work piece of equidimension not.
Wherein a controller for controlling the electric elements is connected to the device, and a distance sensor for detecting the distance between the transmission assembly 35 and the polishing wheel 13 is mounted on the transmission assembly 35.
When the workpiece with the same size is processed, the transmission component 35 moves to the limit value under the action of the telescopic rod 34 along with the abrasion of the polishing wheel 13, at this time, the transmission component 35 cannot meet the compensation of the polishing wheel 13, the telescopic rod 34 is in the limit telescopic length, and the distance between the transmission component 35 and the polishing wheel 13 is detected to be increased along with the loss distance sensor of the polishing wheel 13, at the moment, the transmission component 35 is reset through the telescopic rod 34, meanwhile, in the resetting process, in order to maintain the stable distance between the polishing wheel 13 and the transmission component 35, the distance sensor is enabled to upload data to the controller, the controller controls the connecting rod 19 to rotate on the sliding block 18, further the height adjustment of the cantilever 12 is achieved, the adjusting speed of the cantilever 12 is the same as the telescopic speed of the telescopic rod 34, the height adjustment of the polishing wheel 13 is completed, and when the polishing wheel 13 and the transmission component 35 are in the moving process, namely, the distance between the polishing wheel 13 and the transmission component 35 is kept constant, at this moment, the processing requirement on the workpiece can be normally met, in order to maintain the stable distance between the transmission component 35 and the polishing wheel 13 and the transmission component 35, at the moment, in order to maintain the stable distance between the transmission component 35 and the polishing wheel 35 and the air suction fan 331 is increased, at the same time, the distance between the fan and the fan is increased, namely, the fan is enabled to fully move the air suction fan and the air suction fan 32, and the distance between the fan is increased to be increased, and the air suction fan 331, and the distance can be increased, and the air suction space can be greatly, and the distance can be increased, and the air suction space can be the air gap can be increased, and the air suction space and the air gap and the air can and the air gap 35 and the air can and the air.
It should be emphasized that the difference between the present technical solution and 201910850757.2 is that, by the mutual cooperation between the connecting rod 19 and the transmission assembly 35, the position adjustment of the polishing wheel 13 is reduced while the polishing wheel is ensured to continuously maintain high precision polishing, that is, when the diameter of the abrasion of the polishing wheel 13 is smaller, the position of the transmission assembly 35 is adjusted only by the telescopic rod 34 at this time, so as to drive the workpiece to compensate the abrasion of the polishing wheel 13, in the process of compensation, the polishing wheel 13 can be always in a working state, and meanwhile, when the position of the transmission assembly 35 adjusts the workpiece polishing process, the distance between the workpiece and the ventilation hole 311 is changed, so as to satisfy the requirement that the dust absorption cavity 32 fully absorbs the smoke generated by polishing, the position of the transmission assembly 35 can adjust the suction force of the blower 331, and ensure that the user can always be in a safe and clean space.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
