[0001] The present application relates to the technical field of bearing processing, and in particular to a multifunctional grinding machine for bearing processing. Background Art

[0002] The grinding machine used for bearing processing is a kind of grinding equipment specially used for processing bearing parts. Bearings are usually common parts in mechanical equipment, used to support and position rotating shafts, so the processing accuracy requirements are relatively high. The grinding machine used for bearing processing can perform precision grinding of the inner ring, outer ring, raceway and other parts of the bearing to ensure that the dimensional accuracy, surface quality and geometric shape of the bearing meet the requirements. When grinding and cutting the bearing, it is generally clamped and fixed by its fixture or corresponding fixing parts to ensure its stability during the grinding and cutting process;

[0003] With respect to the above-mentioned related technologies, the inventor believes that the existing bearings are clamped and fixed by the clamps or corresponding fixing parts. Since both the outer ring and the inner ring need to be cut and ground when the bearing is ground and processed, when the inner ring needs to be ground and processed, the outer side needs to be fixed by the clamps or fixing parts. After the inner ring is processed, it may be necessary to manually remove it from the clamp fixing parts on the outer side, and then use the clamp fixing parts on the inner ring to fix the inner side of the bearing, so that the outer ring can be cut and ground. The overall operation is relatively cumbersome, which will also affect the actual processing efficiency.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] The multifunctional grinding machine for bearing processing provided in this application adopts the following technical solution:

The repairing machine as claimed in claim 1, wherein the two said adjusting base are connected to each other with a bolt, and the bolt has a round shank to contact with the two said bearings. The two said bearings are connected by a bolt, and the two said bolts are connected by a screw thread to contact the two said bearings.

[0008] Preferably, the first fixing member includes a fixing frame, the bottom of the fixing frame is fixedly connected to the top of the second cylinder by bolts, a sliding groove is provided on the inner cavity side wall of the fixing frame, and one side of the fixing frame is fixedly connected to the driving motor by bolts.

[0009] Preferably, the driving motor is fixedly connected to a bidirectional screw via an output shaft, and one end of the bidirectional screw away from the driving motor rotates through a fixed frame and extends to the interior of the slide slot, and one end of the bidirectional screw passes through the fixed frame and is rotatably connected to the inner cavity side wall of the slide slot via a rotating shaft.

[0010] Preferably, the surface of the bidirectional screw rod is threadedly connected with two groups of threaded sleeves, and the tops of the two groups of threaded sleeves are fixedly connected to the bottom of the inner clamping plate by bolts.

[0011] Preferably, the second fixing member includes two groups of first cylinders, the bottoms of the two groups of first cylinders are fixedly connected to the top of the processing table by bolts, and the ends of the two groups of first cylinders close to each other are fixedly connected to the side of the outer clamping plate away from each other by bolts.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] Through the coordinated use of the first fixing piece, the second fixing piece and other related components, when the inner ring of the bearing is clamped, the second fixing piece can be raised, thereby transmitting through the driving motor and other components, and fixing the inner ring with the inner clamping plate. When the outer ring needs to be clamped and fixed, the two groups of first cylinders are used to output, and the outer ring is clamped and fixed with the outer clamping plate. At this time, the driving motor is reversed, the two groups of inner clamping plates are loosened, and the second cylinder contracts, driving the fixing frame and related components to enter the chip collecting groove through the through groove. Compared with the prior art, the overall operation is simple and easy to use, and the clamping position can be quickly adjusted according to the cutting and grinding requirements of the inner and outer rings of the bearing, which can effectively improve the actual processing efficiency. At the same time, the elastic anti-slip pad is used to not only improve the stability of the clamping, but also avoid excessive clamping force, which causes wear on the bearing surface.

[0020] By adopting the above technical solution, the bearing to be processed can be placed on the processing table 3 of the grinder body 1, so that the bearing can be cut and ground by using the cutting tool and other components on the grinder body 1, and the grinding debris can enter the chip collection groove 2 below through the chip removal groove 4 opened on the processing table 3, which is convenient for cleaning. At the same time, the first fixing member provided on the top of the second cylinder 12 is used for transmission, which can drive the two groups of inner clamping plates 8 to move, so that the inner ring of the bearing can be supported and fixed, which is convenient for cutting and grinding the outer ring of the bearing. When the outer ring is polished and the inner wall needs to be polished, it can be output through the two groups of first cylinders 6 to drive the two groups The outer clamping plate 7 moves to clamp and fix the outer side of the bearing. At this time, the transmission can be carried out through the first fixing piece to loosen the two sets of inner clamping plates 8, and then the second cylinder 12 is contracted to allow the first fixing piece to pass through the through groove 10 and enter the chip collecting groove 2 below, thereby avoiding it from affecting the cutting and grinding of the inner wall of the bearing by the cutting tool. When the first fixing piece is contracted into the chip collecting groove 2, the inner wall of the bearing can be cut and ground by the relevant cutting components provided on the grinder body 1, and the elastic anti-slip pad 9 can improve its stability in the clamping and fixing process, and at the same time, it can also avoid the wear of the bearing surface due to the clamping force being large enough, thereby affecting its product quality.

[0021] Reference Figure 1 , Figure 2 and Figure 3The first fixing member includes a fixing frame 5, the bottom of the fixing frame 5 is fixedly connected to the top of the second cylinder 12 by bolts, a slide groove 13 is opened on the inner cavity side wall of the fixing frame 5, one side of the fixing frame 5 is fixedly connected to the driving motor 11 by bolts, and the driving motor 11 is fixedly connected to a bidirectional screw rod 14 through an output shaft, and one end of the bidirectional screw rod 14 away from the driving motor 11 rotates through the fixing frame 5 and extends to the inside of the slide groove 13, and the bidirectional screw rod 14 passes through one end of the fixing frame 5 and is rotatably connected to the inner cavity side wall of the slide groove 13 through a rotating shaft, and the surface of the bidirectional screw rod 14 is threadedly connected with two groups of threaded sleeves 15, and the tops of the two groups of threaded sleeves 15 are fixedly connected to the bottom of the inner clamping plate 8 by bolts;

[0022] By adopting the above technical solution, a driving motor 11 is fixedly connected to one side of the fixed frame 5 for output, which can drive the bidirectional screw rod 14 to rotate. Because the surface of the bidirectional screw rod 14 is provided with two sets of opposite thread patterns, and the two sets of threaded sleeves 15 are limited by the sliding groove 13, that is, the two-way screw rod 14 is rotated to drive the two sets of threaded sleeves 15 to move inward or outward at the same time. When moving outward, the two sets of inner clamping plates 8 can be driven to support and fix the inner wall of the bearing. Conversely, the driving motor 11 is reversed, which can drive the bidirectional screw rod 14 to reverse, thereby causing the two sets of inner clamping plates 8 to loosen the bearing.

[0023] The implementation principle of a multifunctional grinding machine for bearing processing in the embodiment of the present application is as follows: first, the bearing to be processed can be placed on the processing table 3 of the grinding machine body 1, so that the bearing can be cut and ground by using the cutting tool and other components on the grinding machine body 1, and the grinding debris can enter the chip collection groove 2 below through the chip discharge groove 4 opened on the processing table 3, which is convenient for cleaning. A driving motor 11 is fixedly connected to one side of the fixing frame 5 for output, which can drive its bidirectional screw rod 14 to rotate, because its bidirectional screw rod 14 surface is provided with two sets of opposite thread patterns, and the two sets of thread sleeves 15 are limited by its slide groove 13, that is, through the rotation of the bidirectional screw rod 14 , driving its two sets of threaded sleeves 15 to move inward or outward at the same time. When moving outward, it can drive its two sets of inner clamping plates 8 to support and fix the inner wall of the bearing, which is convenient for cutting and grinding the outer ring of the bearing. When the outer ring is polished, it is necessary to grind the inner wall, and the two sets of first cylinders 6 can be output to drive the two sets of outer clamping plates 7 to move, so as to clamp and fix the outer side of the bearing. Conversely, the driving motor 11 is reversed, which can drive the bidirectional screw rod 14 to reverse, so that the two sets of inner clamping plates 8 loosen the bearing, and then the second cylinder 12 is contracted to make the first fixing member pass through the through slot 10 into the chip collecting groove 2 below, thereby avoiding It affects the cutting tool's cutting and grinding of the inner wall of the bearing. When the first fixing part is retracted into the chip collecting groove 2, the inner wall of the bearing can be cut and ground by the relevant cutting components provided on the grinder body 1, and the stability of the clamping and fixing process can be improved by the elastic anti-skid pad 9 provided. At the same time, it can also avoid the wear of the bearing surface caused by the clamping force being large enough, thereby affecting the product quality. The above-mentioned first cylinder 6 can choose the DSNU-32-50-PA model. The cylinder is a double-acting cylinder, which means that the cylinder can control the intake and exhaust respectively through two different pipelines to realize the push-pull action. When the cylinder is inflated, the cylinder piston will push outward, thereby And drive the clamping plate to clamp the workpiece. When the air is exhausted, the cylinder piston will retract inward to release the clamping force. By controlling the on and off of the air source, the function of clamping and releasing the workpiece can be realized. The second cylinder 12 can use the CDQ2B32-25DMZ model cylinder. This cylinder belongs to the double-rod cylinder type and adopts the design that both ends of the piston can output force. When working, by controlling the on and off of the air source, the gas pressure in the cylinder will push the piston to move outward or inward, thereby driving the stable extension and retraction of the lifting component. This cylinder has a simple structure and good stability. It is suitable for lifting equipment that requires high stability and precise control. The above-mentioned drive motor 11 can use a NEMA 17 stepper motor. The NEMA 17 stepper motor is a synchronous motor that controls the movement of the rotor by applying a pulse signal. Controlling the rotation angle of the stepper motor is usually achieved by controlling the number of input pulses. Each time a pulse signal is received, the stepper motor will rotate a fixed angle. This angle is called the step angle.The rotation direction of the stepper motor is determined by the sequence of the input pulse signal and the direction of the current. The forward and reverse rotation of the motor can be achieved by controlling the pulse sequence and the current direction. The stepper motor controller is an electronic product that can send uniform pulse signals. After the signal it sends enters the stepper motor driver, it will be converted by the driver into a strong current signal required by the stepper motor to drive the stepper motor to operate. The stepper motor controller can accurately control the stepper motor to rotate through every angle. The overall operation is simple to use. The clamping position can be quickly adjusted according to the cutting and grinding requirements of the inner and outer rings of the bearing, which can effectively improve its actual processing efficiency.
