Description

Technical Field

[0001] This application relates to the field of cloth wheel polishing machine technology, and more specifically, to a mounting bracket and a multi-station cloth wheel polishing machine. Background Technology

[0002] The working principle of a cloth wheel polishing machine is as follows: the motor drives the cloth wheel to rotate at high speed, and the material removal or surface finishing is achieved through the friction and elastic deformation between the cloth wheel and the workpiece surface.

[0003] In existing technology, a pulley is installed on the drive shaft of the motor, and a pulley is also installed on the output shaft of the cloth wheel. The pulley on the drive shaft drives the pulley on the output shaft to rotate through the belt, so as to realize the motor driving the cloth wheel to rotate. Usually, only one cloth wheel is set, which results in low working efficiency of the cloth wheel polishing machine. Therefore, it is necessary to develop a multi-station cloth wheel polishing machine, that is, one motor can drive multiple parallel cloth wheels to rotate simultaneously, so as to realize the simultaneous processing and polishing of multiple workpieces.

[0004] However, the difficulty of multi-station cloth wheel polishing machines lies at least in the fact that when installing the cloth wheels, the cloth wheels are set in a vertical position and multiple cloth wheels need to be installed at the same horizontal height.

[0047] Example 1:

[0048] Please see Figure 1This embodiment provides a mounting bracket, which includes a first bracket 100 and several second brackets 200. The first bracket 100 includes a first mounting plate 110, a first connecting portion 120, and a horizontal mounting groove 130. The first connecting portion 120 and the horizontal mounting groove 130 are both disposed on the outer wall of the first mounting plate 110. The second brackets 200 include a second body 210, a fixing slider 220, a second connecting portion 230, and a third connecting portion 240. The fixing slider 220 is disposed on the back of the second body 210 and is used to be embedded in and slidably connected to the horizontal mounting groove 130. The second connecting portion 230 and the third connecting portion 240 are both disposed on the second body 210. The second connecting portion 230 is used to connect with the first connecting portion 120, and the third connecting portion 240 is used to connect with the cloth wheel unit 500. Figure 3 (as shown in the diagram) The connection allows several cloth wheel unit components 500 to be arranged side by side on the first mounting plate 110.

[0049] In this embodiment, the mounting bracket is used to mount a plurality of cloth wheel unit components 500. The cloth wheel unit components 500 can be driven to rotate by the drive component 300. The workpiece is polished by the friction and elastic deformation between the cloth wheel unit components 500 and the workpiece surface.

[0050] The mounting bracket includes a first bracket 100 and several second brackets 200. The first bracket 100 includes a first mounting plate 110, a first connecting portion 120, and a horizontal mounting groove 130. The first mounting plate 110 is provided with the first connecting portion 120 and the horizontal mounting groove 130. The second brackets 200 include a second body 210, a fixed slider 220, a second connecting portion 230, and a third connecting portion 240. The second body 210 is provided with the fixed slider 220, the second connecting portion 230, and the third connecting portion 240. The fixed slider 220 can be embedded in the horizontal mounting groove 130 and slidably connected to the horizontal mounting groove 130. The second connecting portion 230 is connected to the first connecting portion 120. The third connecting portion 240 is used to install the cloth wheel unit 500.

[0051] For example, when installing the second bracket 200, the fixing slider 220 on the second body 210 can be inserted into the horizontal mounting groove 130 of the first mounting plate 110. Then, the second body 210 can be pushed so that the fixing slider 220 moves along the horizontal mounting groove 130, so that the second connecting part 230 on the second body 210 cooperates with the first connecting part 120 on the first mounting plate 110 to fix the second bracket 200 on the first mounting plate 110 of the first bracket 100. Then, the other second brackets 200 are fixed on the first mounting plate 110 in sequence. Then, the cloth wheel unit 500 can be fixed on the second bracket 200 through the third connecting part 240 to realize that several cloth wheel unit 500 are arranged side by side on the first mounting plate 110.

[0052] The fixed slider 220 is slidably connected to the horizontal mounting groove 130. The sliding connection can provide guidance and has the advantages of flexible adjustment and quick installation. It can flexibly adjust the position of the second bracket 200 and allow the second bracket 200 to move freely in the horizontal direction. It is convenient to adjust the position of the second bracket 200 according to actual needs, and the installation is convenient and can enhance the structural stability.

[0053] Specifically, please refer to Figure 1 The first connecting part 120 includes: a plurality of first threaded holes 121 and a first fixing bolt. The first threaded holes 121 are disposed on the outer wall of the first mounting plate 110. The first fixing bolt is used to connect the first threaded holes 121 and the second connecting part 230 so that the second bracket 200 is fixed to the first mounting plate 110.

[0054] In this embodiment, the first mounting plate 110 is provided with a first threaded hole 121. The second bracket 200 can be fixed in the first threaded hole 121 by a first fixing bolt. Fixing with bolts can quickly lock the position of the second bracket 200 and facilitate disassembly, maintenance or replacement of parts. For example, after the second bracket 200 slides to the designated position along the horizontal mounting groove 130 by the fixing slider 220, the second bracket 200 can be fixed in the first threaded hole 121 by the first fixing bolt.

[0055] Specifically, please refer to Figure 2 The second body 210 includes: a base plate 211, an upper side plate 212 and a lower side plate 213.

A second connecting part 230 is provided on the base plate 211 and a third connecting part 240 is provided on the upper side plate 212 and the lower side plate 213.

[0056] In this embodiment, the upper side plate 212, the base plate 211, and the lower side plate 213 are sequentially connected to form a U-shaped groove structure. The fixing slider 220 is disposed on the back of the base plate 211. When the fixing slider 220 is embedded in the horizontal mounting groove 130, it can be understood that the base plate 211 is in close contact with the first mounting plate 110, while the upper side plate 212 and the lower side plate 213 are equivalent to uprighting the base plate 211. That is, the upper side plate 212 and the lower side plate 213 can ensure the cantilever space of the cloth wheel unit 500, so that the cloth wheel unit 500 and the base plate 211 maintain a certain distance, providing sufficient space for polishing and grinding the workpiece. The base plate 211 is provided with a second connecting part 230, which is equivalent to providing a second connecting part 230 in the groove of the U-shaped groove structure. This can avoid interference between the first fixing bolt in the groove and the cloth wheel unit 500.

[0057] Specifically, please refer to Figure 2 The second connecting part 230 includes: a plurality of elongated holes 231, which are disposed on the base plate 211. The elongated holes 231 are used to connect with the first threaded hole 121, so that the second bracket 200 is fixed to the first mounting plate 110 by the first fixing bolt.

[0058] In this embodiment, the base substrate 211 is provided with a plurality of elongated holes 231. The base substrate 211 can be connected to the first threaded hole 121 on the first mounting plate 110 through the elongated holes 231. Then, the elongated holes 231 and the first threaded hole 121 can be fixed together by the first fixing bolt, so that the second bracket 200 is fixed on the first mounting plate 110. This allows for flexible adjustment of the position of the second body 210. The first fixing bolt can be pre-tightened and then slidably positioned in the elongated hole 231, simplifying the installation process. During disassembly, the position of the second bracket 200 can be adjusted without completely removing the first fixing bolt. For example, the base substrate 211 is provided with two elongated holes 231, which are arranged parallel to each other vertically. Each elongated hole 231 can be fixed by two first fixing bolts.

[0059] Specifically, please refer to Figure 2 The third connecting part 240 is provided with a second threaded hole 241, which is provided on the upper side plate 212 and the lower side plate 213. The second threaded hole 241 is used to fix the cloth wheel unit 500.

[0060] In this embodiment, the cloth wheel unit 500 can be detachably connected to the second threaded hole 241 by bolts, which can achieve quick installation and disassembly.

[0061] Specifically, please refer to Figure 2The fixed slider 220 and the base plate 211 are integrally formed. The base plate 211 is provided with a left side surface 214 and a right side surface 215. The fixed slider 220 extends from the left side surface 214 to the right side surface 215.

[0062] In this embodiment, a fixing slider 220 is provided on the back of the base substrate 211, and the fixing slider 220 extends from the left side 214 to the right side 215 of the base substrate 211. Its structure is stable, easy to disassemble, and easy to implement.
