Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of polishing equipment, and particularly relates to a flexible polishing and grinding device. BACKGROUND

[0002] The existing polishing equipment is mostly used for polishing small workpieces such as mobile phone screens and backshells. Due to the limitation of the workpiece disc and the brush disc, the polishing equipment cannot be used for polishing large-size workpieces. In addition, the polishing trajectory is fixed, which can easily cause repeated polishing, resulting in the problem that the edge part cannot be effectively polished and the yield is low. On the other hand, the driving component is fixedly connected with the polishing disc. The polishing effect is affected by the placement of the workpiece to be polished and the unevenness of the workpiece surface. There is a possibility that the workpiece is scrapped due to poor polishing. At the same time, the existing polishing cannot adaptively adjust the contact surface due to the uneven surface of the workpiece, which affects the polishing effect. Therefore, the present application provides a flexible polishing and grinding device for replacing the existing technology. SUMMARY

[0003] The purpose of the present application is to provide a flexible polishing and grinding device to solve the technical problem that the existing polishing equipment cannot compensate for the unevenness of the workpiece surface and the poor polishing effect caused by the inclination of the workpiece placement.

[0004] The above technical purpose of the present application is achieved by the following technical scheme: a flexible polishing and grinding device, comprising a bearing part for placing a workpiece and a polishing part for polishing and grinding the workpiece, characterized in that it comprises: a first driving part arranged in a first direction of the bearing part, the first driving part driving a second driving part to reciprocate in the first direction of the bearing part, the second driving part being arranged transversely to the first direction, the second driving part driving the polishing part to reciprocate in a second direction of the bearing part, so as to realize polishing and grinding of the workpiece.

[0005] Further, the polishing part comprises a polishing disc, and a plurality of column members are arranged on the upper surface of the polishing disc along the axis;

[0006] The positioning disc is axially distributed with a plurality of sleeve pipes penetrating the positioning disc, the sleeve pipes are slidingly installed on the column members and slide along the column members, and the sleeve pipes are used for connecting the main shaft of the positioning disc, the main shaft is driven by a third driving part to drive the positioning disc to ascend or descend, so as to drive the sleeve of the positioning disc to axially slide along the column member and ascend or descend.

[0007] Further, the outer diameter of the column member is smaller than the inner diameter of the sleeve pipe.

[0008] Compared with the prior art, the present application has the following advantages: by adopting the cooperation of the sleeve and the column, the inner diameter of the sleeve is larger than the outer diameter of the column, after the polishing disc is connected with the part to be polished, the local protrusions on the surface of the part to be polished are compensated due to the slight angle of the inclination of the polishing disc, the flexible fitting of the polishing disc is realized, the phenomenon of unevenness after polishing caused by the ups and downs of the size and thickness of the part to be polished and the ups and downs during placement is avoided, and good applicability and popularization are achieved.

[0012] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0013] In the description of the present application, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0014] In the first embodiment of the present application, as shown in Figure 1 A flexible polishing and grinding device, comprising a bearing part 1 for placing a workpiece and a polishing part 2 for polishing and grinding the workpiece, characterized in that it comprises: a first driving part 3 arranged in a first direction of the bearing part 1, the first driving part 3 driving a second driving part 4 to reciprocate in the first direction of the bearing part 1, the second driving part 4 being arranged transversely to the first direction, the second driving part 4 driving the polishing part 2 to reciprocate in a second direction of the bearing part, so as to realize polishing and grinding of the workpiece.

[0015] The embodiment of the technical scheme is as follows: the component to be polished is placed on the upper surface of the bearing part 1, the second driving part 4 is driven to move along the first direction of the bearing part 1 by the first driving part 3, and the polishing part 2 is driven to move along the second direction of the bearing part by the second driving part 4, so that the polishing part 2 reaches the initial polishing side of the component to be polished.

[0016] In the above technical scheme, the bearing part 1 needs to be as flat as possible, the first driving part 3 and the second driving part 4 adopt one of the following driving modes: screw transmission, gear and rack transmission, hydraulic drive, and pneumatic drive, and the above modes are all conventional technical means for those skilled in the art, so they are not described in detail in the present application.

[0017] The polishing part 4 comprises a polishing disc 5, and a plurality of column members 6 are arranged on the upper surface of the polishing disc 5 along the axis.

[0018] The positioning disc 7 is axially provided with a plurality of sleeve pipes 8 penetrating the positioning disc, the sleeve pipes 8 are slidingly installed on the column members 6 and slide along the column members 6, the outer diameter of the column members 6 is smaller than the inner diameter of the sleeve pipes 8, a main shaft 9 for connecting the positioning disc 7 is provided, the main shaft 9 is driven to rotate by a third driving part 10, and a fourth driving part 11 drives the third driving part 10 to ascend or descend to drive the shaft sleeve of the positioning disc 7 to ascend or descend along the column members in the axial direction.

[0019] By adopting the above technical scheme, after the component to be polished is placed on the bearing table 1, the third driving part 10 is driven to descend by the fourth driving part 11, and the main shaft 9 driven to rotate by the third driving part 10 is synchronously driven to descend, the sleeve pipes 8 of the positioning disc 7 are located at the topmost point of the column members 6 under the action of the gravity of the polishing disc 5 during the descending process of the main shaft 9, the main shaft 9 continues to descend for a distance after the polishing disc 5 contacts the component to be polished, and the polishing disc 5 is attached to the component to be polished by the weight of the polishing disc 5, and at the same time, since the inner diameter of the sleeve pipes 8 is larger than the outer diameter of the column members 6, the polishing disc 5 will tilt by a certain angle after the polishing disc 5 contacts the component to be polished due to the local protrusions on the surface of the component to be polished, so that the flexible attachment of the polishing disc 5 to the component to be polished is realized, and then the main shaft 9 is driven to rotate by the third driving part 10, so that the synchronous rotation of the positioning disc 7 and the polishing disc 5 is realized to polish the component to be polished.
