Description
Technical Field
The invention relates to the technical field of polishing equipment, in particular to a polishing device and a calibration method.
Background
In the surface automatic grinding and polishing of castings and injection molding parts, three track modes are commonly used: a position mode, a passive float mode, and an active control mode.
The position mode is that the track of automatic polishing is fixed, and is generally obtained in a mode based on manual teaching, and is characterized in that the track is fixed, and the defect is that the shape error caused by workpiece manufacturing and clamping cannot be self-adapted. Passive floating mode means that the tool is fixed in a floating manner, and the position of the tool can be passively adjusted when external force is applied, typically represented by an air floating spindle. This approach is suitable for situations where a large abrasive contact force is allowed, such as metal polishing with high-mesh abrasive sheets, while for softer materials, the contact force allowed is smaller and the general floating device stiffness is not satisfactory for passive changes in its position. The main power control mode generally refers to a mode of measuring the stress condition of the polishing positive pressure direction through a force sensor, and the offset of an automatic polishing track in the direction is regulated through a control method, so that the contact force between a polishing tool and a workpiece is controlled, the application scene is similar to that of a passive floating mode, and the defect of the main power control mode is also that the output capability of the micro contact force is limited due to the insufficient bandwidth and precision of the power control. The latter two keep a limited working interval of constant force: theoretically, floating polishing relies on the passive flexibility of a floating tool, can be approximately considered as a constant force in small floating, and after exceeding the working interval, the constant force is difficult to ensure, and overgrinding and overpolishing can occur for plastic materials; the main shaft rotates to cause large force noise when the main power is controlled, and the control precision is insufficient for plastic materials, so that the surface is difficult to be prevented from being damaged.
Summarizing: for the position mode, because the position change of the actual workpiece cannot be self-adapted, an area which is not machined or is over-machined may occur; for passive float and active control modes, the actual control accuracy of the system is not satisfactory when a small contact force needs to be maintained.

Referring to fig. 1 and 2, in one aspect, an embodiment of the present invention discloses a sanding polishing device including a support 10, a sanding assembly, and a force control mechanism.
Specifically, the bracket 10 has a mounting portion 11, the mounting portion 11 being for connection with the outside; the polishing assembly comprises a rotating main shaft 21 and a grinding disc 22, wherein the rotating main shaft 21 is arranged on the bracket 10, the grinding disc 22 is arranged on the rotating main shaft 21, and the grinding disc 22 has elasticity; the force control mechanism comprises a force sensor 31 and contact wheels 32, the force sensor 31 is mounted on the support 10, the contact wheels 32 are provided with two contact wheels 32 which are respectively arranged on two sides of the millstone 22, the force sensor 31 is used for detecting the pressure of the contact wheels 32, and the contact wheels 32 are used for being abutted with a workpiece.
When the polishing device is used for polishing, the polishing device is mounted on a robot or a machine tool, and the robot or the machine tool is used for driving the polishing device to move on the surface of a workpiece. During polishing, the robot or the machine tool drives the contact wheel 32 to extrude with the surface of the workpiece, so that the contact wheel 32 maintains a certain extrusion force with the surface of the workpiece, and the extrusion wheel is always abutted with the workpiece during polishing. The force sensor 31 feeds back the detected pressure of the contact wheel 32 to the robot or the machine tool to guide the robot or the machine tool to act in the axial direction of the rotating spindle 21, so that the pressure is maintained at a set value, and the contact wheel 32 is prevented from crushing the surface of the workpiece.
It should be understood that the rotating spindle 21 may be selected as a pneumatic spindle or an electric spindle according to the application, and may be selected as a spindle that is driven to rotate by other driving methods, and the driving method of the rotating spindle 21 does not affect the technical effects of the grinding and polishing apparatus according to the embodiment of the present invention.
In the embodiment of the invention, the bracket 10 is connected with a robot or a machine tool through the mounting part 11, and the robot or the machine tool drives the grinding and polishing device of the embodiment to move on the surface of a workpiece. The two sides of the grinding disc 22 are provided with contact wheels 32 which are in contact with the surface of the workpiece, the pressure received by the contact wheels 32 is detected by using a force sensor 31, the force sensor 31 feeds back the pressure of the contact wheels 32 to a robot or a machine tool, the robot or the machine tool acts according to the pressure, the pressure between the contact wheels 32 and the surface of the workpiece is maintained within a set contact pressure range, the grinding disc 22 and the surface of the workpiece are ensured to be always attached, and the self-adaption of the position of the workpiece is realized.
When polishing work is performed, the grinding disc 22 and the surface of the workpiece are mutually extruded, and the pressure for polishing the workpiece only comes from the deformation pressure of the grinding disc 22 due to the fact that the relative positions of the grinding disc 22 and the two contact wheels 32 are fixed, so that the pressure between the grinding disc 22 and the workpiece can be kept constant. Furthermore, the contact wheel 32 is arranged such that the pressure between the grinding disc 22 and the workpiece is only related to the deformation of the grinding disc 22, whereas the deformation of the grinding disc 22 in a flat surface is substantially uniform, such that the grinding and polishing device has a strong force-drying resistance and a high constant force accuracy.
In some embodiments, referring to fig. 1, the force control mechanism includes a base 33 and a fixing rod 34, the base 33 is connected with the force sensor 31, the fixing rod 34 is symmetrically disposed on two sides of the rotating main shaft 21, and the contact wheel 32 is fixed on the fixing rod 34. Wherein the axis of the fixing rods 34 at both sides of the grinding disc 22 and the rotation axis of the rotating main shaft 21 are in the same vertical plane.
In some embodiments, the contact wheel 32 is cylindrically shaped, with the direction of rolling of the contact wheel 32 coinciding with the direction of movement of the abrasive disc 22. The cylindrical contact wheel 32 can increase the contact area with the workpiece surface, effectively preventing the contact wheel 32 from crushing the workpiece surface.
It should be noted that the contact wheel 32 is a rigid wheel and that the contact wheel 32 does not deform when subjected to reasonable compressive forces. The contact wheel 32 is a rigid wheel, and the distance between the rotating main shaft 21 and the surface of the workpiece is not changed due to pressure change, so that the deformation generated by the grinding disc 22 in the grinding and polishing process is equal, namely the grinding and polishing pressure of the grinding disc 22 on the surface of the workpiece is equal.
In the embodiment of the invention, the pressure of the grinding disc 22 when grinding and polishing the workpiece is only provided by the elastic deformation of the grinding disc 22, and the contact wheels 32 arranged on the two sides of the rotating main shaft 21 can prevent the distance between the rotating main shaft 21 and the surface of the workpiece from being influenced by other factors (such as pressure change), so that the grinding and polishing pressure is prevented from being influenced by external factors, and the constant grinding and polishing pressure is ensured. The contact wheel 32 is connected with the force sensor 31 through the fixed rod 34 and the base 33, the pressure of the contact force is directly transmitted to the force sensor 31, and the force sensor 31 feeds back the pressure to the robot or the machine tool, so that the pressure between the contact wheel 32 and the surface of the workpiece is maintained at a set value, and the grinding and polishing process is ensured to be always in effective contact with the surface of the workpiece. In addition, since the pressure between the grinding disc 22 and the workpiece surface is provided only by the elastic deformation of the grinding disc 22, irrespective of the pressure to which the contact wheel 32 is subjected, the force-drying resistance of the grinding and polishing apparatus is improved.
In some embodiments, as shown in fig. 1, the polishing assembly further includes a spindle fixture 23 and an adjusting mechanism, the adjusting mechanism is connected to the bracket 10, the spindle fixture 23 is mounted on the adjusting mechanism, the spindle fixture 23 is used for fixing the rotating spindle 21, and the adjusting mechanism is used for adjusting the height of the rotating spindle 21. It should be appreciated that the rotating spindle 21 is not directly connected to the base 33 or the force sensor 31. As can be seen from the figure, the grinding disc 22 is attached to one end of the rotating main shaft 21, and the distance between the grinding disc 22 and the surface of the workpiece can be changed by changing the height of the rotating main shaft 21 by the adjusting mechanism. In other words, the degree of extrusion of the abrasive disc 22 against the workpiece surface, i.e., the polishing pressure, can be adjusted by the adjustment mechanism.
In actual use, the polishing pressures required by different polishing procedures are different, and the height of the rotating main shaft 21 can be correspondingly adjusted according to the process requirements, so that the pressure of elastic deformation generated by the grinding disc 22 is equal to the required polishing pressure.
In some embodiments, the bracket 10 includes a support plate 12, the adjusting mechanism includes a fixing post 241 and a tightening member 242, the fixing post 241 is fixedly mounted on the support plate 12, one end of the tightening member 242 is fixedly connected with the spindle clamp 23, the tightening member 242 has a through hole cooperatively connected with the fixing post 241, and the tightening member 242 is locked and fixed by using a connecting piece. By changing the relative position of the elastic member 242 on the fixed column 241, the height of the rotating main shaft 21 is changed, so that the purpose of adjusting the distance between the grinding disc 2222 and the surface of the workpiece is achieved.
In this embodiment, the connecting member is a bolt, the elastic member 242 is sleeved on the fixing post 241, and the elastic member 242 can be tightened or loosened by tightening or loosening the bolt, so as to facilitate adjusting the height of the rotating spindle 21.
In some embodiments, the fixed column 241 is provided with graduation 2411 lines, which can intuitively reflect the height change of the rotating spindle 21, and facilitate height adjustment.
In some embodiments, the abrasive disc 22 includes a base disc, an elastic member, and a polishing member, which are sequentially stacked, and the base disc is fixed to the rotating main shaft 21. When the surface of the workpiece is polished, the elastic piece generates elastic deformation, and provides extrusion force for the polishing piece, so that the polishing piece and the surface of the workpiece are mutually extruded. It will be appreciated that the base plate is a rigid member that does not deform over a range of pressures. In this embodiment, the elastic member is a sponge.
The embodiment of the invention discloses a calibration method, which comprises the following steps: the height of the grinding disc 22 at the tail end of the rotary main shaft 21 is adjusted to be lower than the lowest position of the contact wheel 32; abutting and extruding the grinding disc 22 with the pressure calibration table until the pressure of the pressure calibration table is equal to the pressure of the grinding disc 22 for grinding and polishing the workpiece; the height of the contact wheel 32 is adjusted so that the contact wheel 32 abuts against the pressure calibration table. At this time, the calibration work is completed, and when the grinding disc 22 is used, only the contact wheels 32 on the two sides of the grinding disc 22 are ensured to be in effective contact with the surface of the workpiece, so that the grinding and polishing pressure of the grinding disc 22 on the workpiece can be considered to be equal to the calibration pressure.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
