Description

A grinding device for precision bearing processing

Technical Field

The utility model relates to the field of grinding devices, in particular to a grinding device for precision bearing processing.

Background Art

At present, a Chinese utility model with announcement number CN209868136U discloses a grinding device for precision bearing processing, including a workbench, a telescopic table and a clamping part. A placement cavity is opened in the middle of the workbench, and the bottom of the placement cavity is fixedly connected to the telescopic table. A fixing seat is welded at the lower end of the telescopic table, and the fixing seat is fixedly connected to the bottom of the placement cavity by fixing bolts. A cavity is opened inside the upper end of the telescopic table, and a clamping part is provided in the cavity. The beneficial effects are: it has higher stability, and can fix both the outer ring and the inner ring of the bearing. When replacing the inner and outer rings of the bearing for grinding, there is no need to replace the fixing device, which is more convenient and quick to use, and the height can be adjusted to cooperate with the grinding device for grinding, thereby improving the grinding work efficiency.

Although the existing grinding device can fix the outer ring and inner ring of the bearing by adjusting the position of the clamping block, there are still other problems during use, such as poor positioning effect, which cannot meet the requirements of fixing the outer ring and inner ring of the bearing at the same time. If only a single circle can be fixed, it needs to be removed and readjusted after the single circle processing, which reduces the processing efficiency of the bearing. In addition, it does not have the dust collection and purification function. The upper grinding part will generate a large amount of dust in the process of grinding the bearing burrs. The dust will float after formation. If inhaled by the human body, it will cause certain damage to the respiratory tract. The practicality is low. In order to solve the above problems, we propose a grinding device for precision bearing processing.

Utility Model Content

The utility model aims to provide a grinding device for precision bearing processing, which solves the problems that the existing grinding device has poor bearing positioning effect and does not have dust collection and purification functions.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a grinding device for precision bearing processing, comprising a machine frame, two grille plates welded inside the machine frame, a fixed frame installed inside the machine frame, a first bidirectional screw and a second bidirectional screw rotatably connected inside the machine frame and the fixed frame respectively, the surfaces of the first bidirectional screw and the second bidirectional screw are threadedly connected with two first threaded blocks and a second threaded block respectively, the tops of the first threaded blocks and the second threaded blocks are respectively welded with a first connecting plate and a second connecting plate, the other ends of the first connecting plate and the second connecting plate are respectively welded with an outer clamping plate and an inner clamping plate, a partition plate is installed inside the machine frame, a suction fan is bolted to the inside of the machine frame through a pad, a filter screen plate is arranged at the bottom of the partition plate, an air outlet is opened on one side of the machine frame, and a door panel is hinged on the front of the machine frame by a hinge.

The adoption of the above technical solution can improve the positioning effect of the device on the bearing, and can fix the outer ring and the inner ring at the same time, reducing the burden of disassembly, assembly and adjustment for personnel. At the same time, it can have a dust collection and purification function to prevent dust from being inhaled into the body with the breathing of surrounding people, thereby improving the surrounding environment.

The utility model is further configured as follows: a first slide rail and a first slider are bolted to the inside of the machine frame and the fixed frame respectively; a second slide rail slidably connected to the first slide rail is welded to the bottom of the first threaded block; and a second slider slidably connected to the first slider is welded to the bottom of the second threaded block.

By adopting the above technical solution, the first slide rail, the first slider, the second slide rail and the second slider are arranged to limit the first thread block and the second thread block respectively, so as to prevent the first thread block and the second thread block from flipping during the lateral movement.

The utility model is further configured as follows: the other ends of the first bidirectional screw and the second bidirectional screw both penetrate the outside of the frame and are respectively welded with a first turning handle and a second turning handle.

By adopting the above technical solution, through the provision of the first turning handle and the second turning handle, it is convenient for personnel to rotate the first bidirectional screw and the second bidirectional screw.

The utility model is further configured as follows: the top and the bottom of the filter screen plate are both clamped with clamping seats, and the other sides of the two clamping seats are bolted to the partition plate and the machine frame respectively.

By adopting the above technical solution, the filter screen plate can be limited by setting the holder to prevent the filter screen plate from falling down when being blown by wind.

The utility model is further configured as follows: a guide plate is welded between the top of the partition plate and the machine frame.

By adopting the above technical solution, the dust and impurities can be guided by setting the guide plate, so that the fallen dust and impurities can fall onto the partition plate and be sucked in by the suction fan.

The utility model is further configured as follows: a dustproof net is bolted to one side of the machine frame.

By adopting the above technical solution, the dust can be intercepted by setting the dustproof net, thereby preventing external dust from entering the frame through the air outlet.

The utility model is further configured as follows: the first bidirectional screw and the second bidirectional screw are both made of stainless steel.

By adopting the above technical solution, the first bidirectional screw and the second bidirectional screw have the characteristics of high strength, low density and excellent corrosion resistance.

In summary, the utility model has the following beneficial effects:

1. The utility model fixes the machine frame below the grinding piece first, and then puts the bearing into the grid plate so that the outer ring and the inner ring are between the outer clamping plate and the inner clamping plate. After the bearing is placed, first hold the first handle by hand to rotate it. When the first handle is rotated, the two first thread blocks will move together. When the first thread blocks move together, they will drive the outer clamping plate to fix the outer ring of the bearing through the fixation of the first connecting plate. Then hold the second handle by hand to rotate it. When the second handle is rotated, the two second thread blocks will move outward synchronously. When the second thread block moves outward, it will drive the inner clamping plate to move outward to fix the inner ring of the bearing through the fixation of the second connecting plate, which can improve the positioning effect of the device on the bearing, and can fix the outer ring and the inner ring at the same time, reducing the burden of disassembly, assembly and adjustment for personnel.

2. The utility model starts the suction fan through the bearing during grinding. After the suction fan is started, the internal impeller will rotate. The impeller will generate suction when rotating and suck in the dust and impurities above through the suction end. After being sucked in, the dust and impurities will be sent to the partition plate through the air outlet end. The dust-containing gas will pass through the filter screen when being discharged through the air outlet. The filter screen will intercept the dust and impurities in the gas, and can have the dust collection and purification function to prevent dust from being inhaled into the body with the breathing of surrounding people, thereby improving the surrounding environment.
