Technical Field

[0001] The utility model relates to the technical field of base surface grinders, in particular to a high-rigidity ball base surface grinder suitable for large curvature. Background Art

[0002] As the name implies, the ball base grinder is a finishing device for circular parts. It is used for finishing and grinding various products such as internal and external cylindrical surfaces, conical surfaces, and planes. Tapered rollers are important components of tapered roller bearings, and tapered rollers need to go through a grinding process before entering the next process. Among them, the tapered rollers need to have their ball base surfaces ground. This process can be processed using a grinder.

[0005] Therefore, we proposed a high-rigidity ball-based surface grinder that can adapt to large curvatures in order to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide a high-rigidity ball-based surface grinder that is adaptable to large curvatures, so as to solve the problem that the fixed grinding wheel cannot be raised or lowered in the above-mentioned background technology, so the tapered roller grinder can only adapt to tapered rollers with one curvature and cannot process large curvatures on the processed tapered roller surface.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-rigidity ball-based surface grinder adaptable to large curvature, comprising a lower base, a first hydraulic telescopic rod, a pulley assembly and a rotating wheel;

[0008] The invention is characterized in that an upper base is slidably mounted on the lower base, and a sleeve-type transmission lifting mechanism is arranged on the upper base. The sleeve-type transmission lifting mechanism can increase the axial rigidity of the transmission system when the grinder is working and control the lifting and lowering of the grinding mechanism, thereby making the grinding mechanism more precise and stable in grinding the tapered roller to be processed. At the same time, the grinding machine can also adapt to a larger curvature during the processing process as the grinding mechanism is lifted and lowered.

[0009] Furthermore, a second hydraulic telescopic rod is fixedly installed inside the lower base, and a first rotating rod is rotatably installed on the upper end surface of the second hydraulic telescopic rod.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The height of the working grinding disc can be adjusted by the first hydraulic telescopic rod, so that the grinding machine can adapt to tapered rollers with different curvatures. At the same time, the transmission shaft is driven by the motor through the rotating wheel and the pulley assembly, and multiple bearings are arranged on the transmission shaft, which ensures that the transmission shaft and the grinding disc have good rigidity during the rotation process, so that the grinding disc and the transmission shaft are not prone to shaking during the working process, so that the grinding mechanism can grind the tapered rollers to be processed more finely and stably. At the same time, the grinding machine can adapt to larger curvatures during the processing process as the grinding mechanism rises and falls;

[0017] 2. The movable block can prevent the upper base from tilting during its movement on the lower base, so that the upper base can move more stably. The movable block is fixedly mounted on the left and right sides of the outer surface of the upper base. The upper base will drive the movable block to move synchronously on the lower base during its movement. At the same time, the movable block is set in a groove opened on the lower base;

At the same time, the first moving rod and the second moving rod are both slidably mounted on the limit rod, and the first moving rod and the second moving rod are both provided with sliders to ensure that the first moving rod and the second moving rod will not be skewed during the movement, thereby enhancing the stability of the first moving rod and the second moving rod when moving;

[0019] 4. The first chuck and the second chuck can realize the function of automatically fixing the tapered roller to be processed. The first expansion plate is located outside the horizontal plane of the second expansion plate. When the threaded rod hits the impact head, the impact head will push the second expansion plate outward through the second rotating rod. The second expansion plate moves outward and drives the first expansion plate to move synchronously, realizing the function of automatically expanding and fixing the tapered roller to be processed;

[0020] 5. The threaded rod is set in the threaded hole opened on the first chuck. The telescopic distance between the threaded rod and the first chuck can be adjusted by rotating the threaded rod, and then the pressing position of the rotating threaded rod and the impact head can be adjusted. At the same time, the anti-loosening nut sleeved on the outside of the threaded rod can fix the adjusted threaded rod, so that the expansion position of the second expansion plate can be controlled by adjusting the threaded rod, thereby enhancing its practicality.
