Description

Technical Field

[0001] This utility model relates to the technical field of polishing machine equipment, and in particular to a lower plate cleaning device for a double-sided polishing machine. Background Technology

[0002] Currently, grinding and polishing machines are used in an increasingly wide range of industries, and the types of polishing slurries used as intermediate media in grinding and polishing are also increasing. They are no longer limited to ordinary polishing slurries, but increasingly include those with added special chemicals. This has created several problems, one of which is product handling. After a batch of products has been polished, we need to quickly rinse off the chemical solution. This is not only for easy manual handling, but more importantly, the polishing process is timed and quantitative. If the product remains in the chemical solution after polishing, it will significantly affect the product quality.

[0003] However, manual rinsing is very inconvenient when cleaning existing double-sided polishing machines, and it can also result in uneven cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device for the lower plate of a double-sided polishing machine to solve the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a lower plate cleaning device for a double-sided polishing machine, comprising a worktable with supporting legs connected to its bottom. Four arc-shaped slag discharge holes are formed at the top of the worktable, and a slag collection bucket is connected below each of the four arc-shaped slag discharge holes. A lower grinding disc is connected above the worktable via a first driving assembly. A protective cover is provided on the outer side of the lower grinding disc and is fixed to the worktable. Two symmetrically arranged clamping assemblies are installed on the protective cover, and a cleaning assembly is provided between the two clamping assemblies. The cleaning assembly is mounted on the protective cover and includes an adjusting motor installed on the inner wall of the protective cover. A swing arm is vertically connected to the rotating shaft of the adjusting motor. A brush is provided at the bottom of the swing arm, and a water distribution pipe is fixed to the front end face of the swing arm. Several nozzles are connected to the bottom of the water distribution pipe, which is connected to an external water source via an inlet pipe. A top plate is connected above the lower grinding disc via a lifting assembly, and an upper grinding disc is connected below the top plate via a second driving assembly.

[0007] Furthermore, the first drive assembly includes a first motor fixed to the bottom surface of the worktable, the output end of the first motor is connected to a rotating shaft, and the rotating shaft passes through the worktable via a bearing and is connected to the lower grinding disc.

[0008] Furthermore, the clamping assembly includes a clamping plate and a first hydraulic cylinder mounted on the outer wall of the protective cover, wherein the telescopic end of the first hydraulic cylinder passes through the protective cover and is connected to the clamping plate.

[0009] Furthermore, an anti-slip pad is provided on the end face of the clamping plate away from the first hydraulic cylinder.

[0010] Furthermore, the lifting assembly includes two symmetrically arranged second hydraulic cylinders and a fixed rod connected to the telescopic end of the second hydraulic cylinders. The other end of the fixed rod is connected to the top plate, and the second hydraulic cylinders are fixed to the outer wall of the protective cover.

[0011] Furthermore, the second drive assembly includes a second motor mounted on the top plate, the output end of the second motor being connected to a rotating shaft, the rotating shaft passing through the top plate via a bearing and being connected to the upper grinding disc.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This invention uses a motor to move a brush onto a lower grinding disc, and a nozzle sprays water onto the lower grinding disc. As the lower grinding disc rotates, it cleans the surface, reducing manual labor, lowering costs, and greatly improving work efficiency. Attached Figure Description

[0018] like Figure 1-2 As shown, a bottom plate cleaning device for a double-sided polishing machine includes a worktable 1, with a support leg 2 connected to the bottom of the worktable 1, and four arc-shaped slag discharge holes 3 opened on the top of the worktable 1, with a slag receiving bucket 4 connected below the four arc-shaped slag discharge holes 3.

[0019] A lower grinding disc 5 is connected above the worktable 1 via a first drive assembly. The first drive assembly includes a first motor 14 fixed on the bottom surface of the worktable 1. The output end of the first motor 14 is connected to a rotating shaft. The rotating shaft passes through the worktable 1 via a bearing and is connected to the lower grinding disc 5.

[0020] The outer side of the lower grinding disc 5 is provided with a protective cover 6, which is fixed on the worktable 1. Two symmetrically arranged clamping assemblies are installed on the protective cover 6. The clamping assembly includes a clamping plate 15 and a first hydraulic cylinder 16 installed on the outer wall of the protective cover 6.
