Description

Technical Field

[0001] The utility model belongs to the technical field of polishing equipment, and in particular relates to a polishing equipment for quickly replacing a polishing disc. Background Art

[0002] In the polishing equipment, polishing consumables are attached to the surface of the polishing disc, and the motor is used to drive the polishing disc to rotate and contact the workpiece for polishing. Since the bearings connected to the polishing disc are wearing parts with limited life, they need to be replaced regularly to ensure the normal operation of the polishing disc.

[0003] However, in the related art, the polishing disc and the motor are directly connected to form an integral structure. During the bearing replacement process, the polishing equipment needs to be shut down, and then the connection structure between the polishing disc and the motor needs to be removed before the bearing can be replaced. The bearing replacement steps are relatively cumbersome, and after replacing the new bearing, the polishing disc's equal height concentricity and other parameters need to be readjusted, which takes a lot of time.

[0004] In view of this, this application is proposed. Utility Model Content

[0005] The purpose of this application is to provide a polishing device with a quick replacement of polishing discs to solve the above-mentioned technical problems existing in the prior art.

[0006] This application is implemented as follows:

[0007] The present application provides a polishing device for quickly replacing polishing discs, comprising a base, a motor, a polishing disc assembly and a coupling; the motor is mounted on the base, and the output shaft of the motor is connected to the polishing disc assembly via a coupling, wherein the coupling comprises a first sub-coupling and a second sub-coupling, the first sub-coupling is fixed to the output shaft of the motor, the second sub-coupling is fixed to the polishing disc assembly, and the first sub-coupling and the second sub-coupling are detachably connected.

[0008] The technical solution adopted in this application can achieve the following beneficial effects:

[0009] In the present application, the first sub-coupling is fixed to the output shaft of the motor, and the second sub-coupling is fixed to the polishing disk assembly. By virtue of the feature that the first sub-coupling can be detachably connected to the second sub-coupling, the polishing disk assembly on the motor output shaft can be quickly replaced, thereby simplifying the replacement steps and improving the replacement efficiency. Moreover, since all the polishing disk assemblies on the motor output shaft are replaced, the position of the polishing disk in the new polishing disk assembly can be adjusted in advance, and the parameters such as the equal height and concentricity of the polishing disk can be adjusted in advance, so that after the polishing disk assembly is replaced, there is no need to spend too much time to adjust the position of the polishing disk again, thereby saving the replacement time of the polishing disk and improving the replacement efficiency of the polishing disk. In addition, the downtime of the polishing equipment is also shorter, which has less impact on the operation of the polishing equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0025] Some embodiments of the present application provide a polishing device for quickly replacing a polishing disc 310, referring to Figures 1 to 12 As shown, it includes a base 100, a motor 200, a polishing disc assembly 300 and a coupling 400, which can quickly replace the polishing disc 310 and improve the polishing efficiency of the polishing disc 310.

[0026] The base 100 serves as an installation body and provides an installation body for the motor 200. The motor 200 is installed on the base 100 and fixed to the base 100. The output shaft 210 of the motor 200 is connected to the polishing disc assembly 300 through a coupling 400. Through the connection of the coupling 400, the rotational motion of the output shaft 210 drives the polishing disc 310 to rotate after a series of transmissions, and the polishing disc 310 is used to polish the object.

[0027] The coupling 400 includes a first sub-coupling 410 and a second sub-coupling 420. The first sub-coupling 410 is fixed to the output shaft 210 of the motor 200, and the second sub-coupling 420 is fixed to the polishing disk assembly 300. The first sub-coupling 410 and the second sub-coupling 420 are detachably matched and plug-in-connected to achieve quick installation and disassembly, so that the polishing disk assembly 300 to be replaced can be quickly removed from the output shaft 210 of the motor 200, and the new polishing disk assembly 300 can be quickly installed to the output shaft 210 of the motor 200, thereby completing the replacement of the polishing disk assembly 300. The replacement procedure is simple, the operation is convenient, and the replacement efficiency is high.

[0028] Furthermore, since the polishing disc assembly 300 is directly replaced, the installation method and installation position of the first sub-coupling 410 and the second sub-coupling 420 are stable and unchanged, and the first sub-coupling 410 and the second sub-coupling 420 can be stably docked. Therefore, the parameters such as the height and concentricity of the polishing disc 310 in the polishing disc assembly 300 can be adjusted in advance. After replacing the polishing disc assembly 300, it is not necessary to spend too much time to re-adjust the height and concentricity of the polishing disc 310, which can shorten the downtime of the polishing equipment and reduce the impact of replacing the polishing disc 310 on the production and operation of the polishing equipment. Fig. 9 As shown, the polishing disc assembly 300 is connected to the second sub-coupling 420, referring to Fig.12 As shown, the motor 200 is connected to the first sub-coupling 410. The second sub-coupling 420 has a metal claw plate, and the first sub-coupling 410 is formed by connecting the metal claw plate and the plum blossom pad. The second sub-coupling 420 can be directly snapped into the first sub-coupling 410 to complete the connection between the polishing disc assembly 300 and the output shaft 210 of the motor 200.

[0029] The coupling 400 can be directly selected from the coupling 400 on the market for use, with the same specifications. Even if a new polishing disc assembly 300 is replaced, the second sub-coupling 420 connected to the new polishing disc assembly 300 can still be quickly and stably connected to the first sub-coupling 410. In some preferred embodiments, the coupling 400 can select a plum key coupling 400, which can quickly and easily connect and correct the universal connection to prevent the occurrence of accelerated wear between components due to eccentric connection.

[0030] The motor 200 is generally installed inside the base 100, and the housing of the base 100 is used to protect the motor 200 to a certain extent. The polishing disc assembly 300 is arranged outside the base 100 to facilitate the polishing and grinding work of the polishing disc 310. In addition to the polishing disc 310, the polishing disc assembly 300 also includes a rotating shaft 320, a chassis 330 and a first bearing 340. Figures 3 to 7 As shown, one end of the rotating shaft 320 is fixed to the second sub-coupling 420, and the other end is fixed to the polishing plate 310. The output shaft 210 of the motor 200 transmits the rotational motion to the rotating shaft 320 by means of the first sub-coupling 410 and the second sub-coupling 420, and then the rotating shaft 320 drives the polishing plate 310 to rotate. The rotating shaft 320 and the polishing plate 310 are usually connected by a key. The chassis 330 and the first bearing 340 are both sleeved outside the rotating shaft 320, and the first bearing 340 is fixed between the inner peripheral wall of the chassis 330 and the outer peripheral wall of the rotating shaft 320 to ensure the smooth rotation of the rotating shaft 320. In addition, in the axial direction of the rotating shaft 320, the end of the chassis 330 away from the polishing plate 310 is detachably connected to the base 100.

[0031] The chassis 330 is detachably connected to the base 100, and the positions of the chassis 330 and the base 100 can be fixed. In addition, the chassis 330 can also stabilize the installation position of the first bearing 340, thereby stabilizing the positions of the rotating shaft 320 and the polishing disc 310 fixed to the rotating shaft 320, ensuring that the polishing disc 310 can rotate stably and avoiding the shaking of the polishing disc 310 during the rotation process. In addition, since the polishing disc assembly 300 is located outside the base 100 and the motor 200 is located inside the base 100, the surface of the base 100 is provided with an assembly hole 110 to match the positions of the two, so that the output shaft 210 of the motor 200 can be smoothly connected to the rotating shaft 320 through the coupling 400. The chassis 330 is fixed outside the base 100, and the assembly hole 110 can also be covered and sealed to prevent impurities from falling and affecting the normal rotation of the motor 200 and the rotating shaft 320.

[0032] In some preferred embodiments, the base 100 is provided with a receiving groove 120, and a sealing ring 600 is installed in the receiving groove 120. Figure 4 As shown, the sealing ring 600 is tightly disposed between the chassis 330 and the base 100 to seal the gap between the chassis 330 and the base 100 , thereby improving the sealing effect of the chassis 330 on the inside of the base 100 .

[0033] In some embodiments provided in the present application, a base 100 is installed with at least two sets of polishing disc assemblies 300, each set of polishing disc assemblies 300 is connected to the output shaft 210 of the motor 200 through a coupling 400, and the polishing discs 310 of each polishing disc assembly 300 can be used normally. In order to improve the polishing effect of the polishing equipment, there are two types of polishing disc assemblies 300, namely, a first-class polishing disc assembly and a second-class polishing disc assembly. The first-class polishing disc assembly or the second-class polishing disc assembly can be installed on the output shaft 210 of the motor 200 according to actual needs. The first-class polishing disc assembly reference Figure 3 and Figure 4 As shown, the rotation center axis of the polishing disc 310 is coaxially arranged with the output shaft 210. Figures 5 to 7 As shown, the rotation center axis of the polishing disc 310 is eccentrically arranged relative to the axis of the output shaft 210, and the rotation range of the polishing disc 310 is larger, which is different from the processing effect and processing range of the first type of polishing disc assembly. The two types of polishing disc assemblies 300 are used together to improve the application range and polishing effect of the polishing equipment.

[0034] In a specific implementation, the second type of polishing disc assembly also includes an eccentric shaft 350, a second bearing 360 and a counterweight 370. The end of the rotating shaft 320 of the second type of polishing disc assembly away from the second sub-coupling 420 is provided with a mounting groove 321. The axis of the mounting groove 321 is eccentrically arranged relative to the axis of the output shaft 210. Part of the eccentric shaft 350 is installed in the mounting groove 321. The second bearing 360 is sleeved outside the eccentric shaft 350 and fixed between the peripheral wall of the eccentric shaft 350 and the groove wall of the mounting groove 321 to ensure the smooth rotation of the eccentric shaft 350. The end of the eccentric shaft 350 away from the mounting groove 321 is fixed to the polishing disc 310, and the polishing disc 310 is driven to rotate by the rotation of the eccentric shaft 350. The counterweight 370 is fixed to the rotating shaft 320, and the axis of the eccentric shaft 350 is located on both sides of the axis of the output shaft 210, refer to Fig.10 and Fig.11 As shown, Fig.11 In order to more clearly see the eccentric shaft 350 which is eccentrically arranged, the polishing disc 310 is not shown.

[0035] When the motor 200 rotates at high speed, the output shaft 210 drives the rotating shaft 320 to rotate. The friction between the rotating shaft 320 and the eccentric shaft 350 and the inertia of the eccentric shaft 350 can make the eccentric shaft 350 rotate, so that the polishing disc 310 can rotate for polishing. The counterweight 370 is fixed to the rotating shaft 320 to prevent the eccentric shaft 350 and the polishing disc 310 from vibrating and jumping during high-speed rotation, thereby ensuring the stable rotation of the polishing disc 310. The weight of the counterweight 370 needs to be obtained by testing on a dynamic balancing instrument, and the weight of the counterweight 370 is determined according to the size of the polishing disc 310, and the weight of the counterweight 370 needs to be accurate to grams.

[0036] In some specific embodiments, reference Figure 7 As shown, the mounting groove 321 includes a first sub-groove 321a and a second sub-groove 321b arranged in sequence from the output shaft 210 to the polishing plate 310. The radial dimension of the second sub-groove 321b is greater than the radial dimension of the first sub-groove 321a. The second bearing 360 is located inside the second sub-groove 321b. Due to the size difference between the second sub-groove 321b and the first sub-groove 321a, the outer ring of the second bearing 360 can abut against the bottom wall of the second sub-groove 321b. The bottom wall of the second sub-groove 321b supports the second bearing 360 and stabilizes the position of the second bearing 360. A gland is provided at the other end of the second bearing 360 to fix the second bearing 360.

[0037] The second polishing disc assembly also includes a fastener 380, reference Figure 7As shown, the fastener 380 is installed at the end position of the eccentric shaft 350 away from the polishing disk 310, and is located in the first sub-groove 321a of the mounting groove 321. The fastener 380 abuts against the inner ring of the second bearing 360 to fix the position of the inner ring of the second bearing 360 and ensure the stability of the position of the second bearing 360.

[0038] In some embodiments of the present application, the polishing device further includes a connecting member 500, and a mounting hole 110 is provided on the surface of the base 100. Figure 8 The connector 500 is installed in the assembly hole 110, referring to Figures 3 to 7 As shown, the connecting member 500 is sleeved outside the coupling 400, and the coupling 400 is connected to the motor 200 located in the base 100 and the polishing disc assembly 300 located outside the base 100 through the assembly hole 110. Part of the connecting member 500 is located inside the base 100 and is fixedly connected to the motor 200, and part of the connecting member 500 is located outside the base 100 and is fixedly connected to the base 100, and the connection stability between the motor 200 and the base 100 is improved by the connecting member 500.

[0039] In some preferred embodiments, the motor 200 may be a motor 200 having output shafts 210 at both ends. Figure 3 and Figure 5 As shown, both ends of the motor 200 are provided with output shafts 210, and both output shafts 210 can be connected to the polishing disc assembly 300. Under such a layout, the number of motors 200 can be reduced, and the layout space in the base 100 can be optimized, so that the volume of the base 100 can be reduced with the same number of polishing disc assemblies 300, thereby reducing the installation space required for the entire polishing device. In addition, both ends of the motor 200 are fixed with connectors 500, and the motor 200 is directly fixed by two connectors 500, so as to stabilize the position of the motor 200 in the base 100 and improve the convenience of installing the motor 200.

[0040] In some other preferred embodiments, there may be multiple motors 200, all of which are located inside the base 100, and the multiple motors 200 are arranged in sequence along the length direction of the base 100, and the projections of the output shafts 210 of any two adjacent motors 200 along the length direction of the base 100 are arranged perpendicular to each other. Figures 1 to 3 as well as Figure 5As shown, under such a layout, the output shafts 210 of adjacent motors 200 can be extended in different directions, and the polishing disc assembly 300 fixed with the output shaft 210 can have enough space to be placed, which can avoid the polishing disc assemblies 300 installed with the output shafts 210 of two adjacent motors 200 from squeezing each other, and further optimize the layout space of the base 100. The space between the two motors 200 whose output shafts 210 extend in the same direction can be fully utilized. In addition, the polishing disc assembly 300 is located on different sides of the base 100, and the types of the polishing disc assemblies 300 on different sides can be set to be inconsistent. In this way, by rotating the base 100, the polishing disc 310 in contact with the object to be polished can be quickly replaced, thereby improving the polishing efficiency. Furthermore, the output shaft 210 is set at both ends of the motor 200, which can further increase the number of polishing disc assemblies 300 that can be installed on the base 100, and improve the processing efficiency of the polishing equipment.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
