Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, in particular to a bearing steel ball polishing machine. Background Art

[0002] Steel balls are divided into grinding steel balls, forging steel balls, and casting steel balls according to the production and processing technology. They are divided into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, etc. according to the processing materials. Alloy steel balls are a kind of spherical iron alloy wear-resistant body with carbon, chromium, manganese, molybdenum and other metal elements added as the main elements, and are produced by forging, spinning, rolling and casting. In the process of producing steel balls, a ball polishing machine is often required to pressurize and file the cold heading ball embryos.

[0003] After the existing bearing steel ball polishing machine polishes the steel balls, it is necessary to manually screen out the steel balls that meet the size standards, and then perform secondary processing on the steel balls that do not meet the standards, which wastes manpower and reduces efficiency.

[0004] For example, a high-efficiency light ball machine (authorization announcement number CN220427829U) can reduce the impact force exerted by the top grinding disc on the steel balls and bottom grinding disc. The four compression springs ensure the stability of pressure transmission after compression, keeping the steel balls in a stable pressure state. This prevents a decrease in pressure and fit between the steel balls and the top grinding disc, thereby improving the filing speed and processing efficiency of the steel balls. However, this device has the following problem: during use, it cannot effectively and automatically screen out substandard steel balls, wasting manpower and reducing efficiency. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bearing steel ball polishing machine, comprising: a box body and a connecting frame arranged at the top of the box body; a circular groove is provided at the top of the connecting frame, a fixing plate is welded to the inner wall of the circular groove, a telescopic rod is installed at the top of the fixing plate, a connecting plate is installed on the movable part of the telescopic rod, a collecting cylinder is welded to the top of the connecting disk, a bottom grinding disk is installed at the top of the collecting cylinder, a leakage groove extending upward for the polished bearing steel balls to pass through is provided at the bottom end of the collecting cylinder, a plurality of material discharge chutes are provided at the top of the connecting disk, a connecting cylinder is welded to the top of the connecting disk, a forward and reverse motor is installed at the top of the connecting cylinder, and a mounting groove extending upward is provided at the bottom end of the connecting cylinder;

[0007] The driving end of the forward and reverse motor is sleeved with a mounting plate that fits the inner wall of the mounting groove through an automatic rod, and a limiting ring that wraps the circular groove is fixed on the top of the connecting frame.

[0008] In a further embodiment, four supporting frames are welded to the top of the connecting frame, and connecting plates are welded to the vertical inner walls of the four supporting frames.

[0010] In a further embodiment, the top end of the top plate is connected to a mounting plate via bolts, and a hydraulic cylinder is installed on the top end of the mounting plate.

[0011] In a further embodiment, the driving end of the hydraulic cylinder is connected to a rotary motor via a hydraulic rod, and the driving end of the rotary motor is fixed to a top grinding disc via a connecting rod.

[0012] In a further embodiment, a bellows is fixed to the vertical side surface of the box body, and a plurality of fans are installed on the vertical side surface of the bellows.

[0013] In a further embodiment, a collection box is closely attached to the vertical inner wall of the box body, and a filter screen is installed on the vertical side surface of the collection box.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are:

[0015] After the grinding is completed, the bearing steel ball polishing machine uses the telescopic rod arranged at the top of the fixed plate to extend and retract, driving the connecting plate to move upward, so that the bottom grinding plate lifts the steel ball, and then under the limit of the limiting ring, the steel ball slides from the bottom grinding plate, so that the steel balls that meet the standards fall into the collection cylinder through the leakage groove, and the steel balls of larger sizes are left outside the collection cylinder for secondary processing. At the same time, the forward and reverse motors arranged at the top of the connecting cylinder drive the mounting plate to rotate, breaking up the steel balls on the top of the connecting plate, so that the smaller steel balls that do not meet the standards fall into the collection box through the discharge chute, and the steel balls that meet the standards are left inside the collection cylinder.

[0016] This device is different from the existing device that requires manual screening of steel balls. It automatically screens steel balls during use, saving manpower, facilitating secondary processing of larger steel balls, screening out smaller steel balls, and improving efficiency. This bearing steel ball polishing machine saves manpower, facilitates secondary processing of larger steel balls, screening out smaller steel balls, and improving efficiency.

At the same time, the forward and reverse motor 20 provided at the top of the connecting tube 21 drives the mounting plate 23 to rotate, breaking up the steel balls at the top of the connecting disc 26, so that the smaller steel balls that do not meet the size standards fall into the collection box 10 through the discharge chute 19, and the qualified steel balls remain inside the collecting tube 27.

[0030] Unlike existing devices that require manual screening of steel balls, this device automatically screens steel balls during use, saving manpower, facilitating secondary processing of larger steel balls, and screening out smaller steel balls, thereby improving efficiency. The driving end of the forward and reverse motor 20 is connected to a mounting plate 23 that fits the inner wall of the mounting groove 22 via an automatic rod, and a limiting ring 7 that wraps around the circular groove 12 is fixed to the top of the connecting frame 9.

[0031] The leakage trough 16 is for the steel balls of the largest size that meet the standards to pass through, and the discharge trough 19 is for the steel balls of smaller size than the standard to pass through. Four support frames 2 are welded to the top of the connecting frame 9, and the vertical inner walls of the four support frames 2 are welded with connecting plates 8.
