Description

Technical Field

[0001] This application relates to the field of bearing processing technology, specifically to a high-efficiency bearing inner ring groove grinding device. Background Technology

[0002] Bearings, as key basic components in mechanical equipment, are widely used in various industrial fields such as automobiles, aerospace, wind power generation, high-speed railways, and precision machine tools. With the increasing demands of modern industry for equipment precision, reliability, and service life, the manufacturing precision and surface quality standards for bearings are becoming increasingly stringent. The surface roughness, geometric accuracy, and dimensional consistency of the bearing inner ring raceway directly affect the bearing's operating accuracy, service life, and noise level, making it a critical process in bearing manufacturing. Currently, the finishing of bearing inner ring raceways mainly employs traditional mechanical grinding equipment and existing automated grinding equipment. While this improves processing efficiency to some extent, it generally suffers from drawbacks such as complex structure, difficulty in adjustment, and poor adaptability. Especially when processing bearings of different specifications, the long equipment adjustment cycle and extended production preparation time affect overall production efficiency. Furthermore, most methods use single-point or double-point grinding, resulting in limited grinding coverage. Multiple positioning and repetitive processing are required to complete the grinding of the entire raceway, which not only prolongs the processing cycle but also increases the risk of accumulated positioning errors.

[0009] As a preferred technical solution of this application, the grinding wheel adopts a replaceable structure and is installed on the rotating shaft by threaded connection or snap-fit ​​method.

[0010] As a preferred technical solution of this application, the adjusting shaft is a threaded shaft, and the grinding seat is connected to the adjusting shaft through a threaded pair.

The grinding wheel adopts a replaceable structure and is installed by threaded connection or snap-fit ​​method. Different specifications and materials of grinding wheels can be quickly replaced according to different processing requirements, enhancing the process adaptability of the equipment.

Detailed Implementation

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0017] Please see Figure 1-3 This application provides a technical solution: a high-efficiency bearing inner ring groove grinding device, including a lower support 9, a guide groove 10 is provided on the upper surface of the lower support 9, a rotating support shaft 2 is provided in the guide groove 10, and a connecting support is provided on one side of the guide groove 10, the connecting support being connected to a grinding mounting seat 4.

[0018] The lower support 9 is the supporting structure for the entire grinding device, bearing the function of the upper components and ensuring the stability and rigidity of the overall operation of the equipment. It is made of high-strength cast iron or steel and has good compressive and vibration resistance.

[0019] The guide groove 10 provides an installation position for the grinding mounting seat 4, and plays a supporting and positioning role, ensuring that the entire device has a compact structure and stable movement.

[0020] Rotary support shaft 2 is used to mount the bearing inner ring to be processed; it rotates under the drive of the drive system, so that the bearing inner ring can be uniformly ground around its entire circumference.

[0021] The connecting support securely connects the guide groove 10 to the grinding mounting seat 4, ensuring that the relative positions of the two are fixed and preventing displacement due to vibration or force.

[0022] The grinding mounting base 4 supports the grinding assembly and forms an integral structure with the connecting support and guide groove 10, ensuring the coordinated work of each component during the grinding process. It can be adjusted laterally or longitudinally as needed to adapt to the processing of bearings of different specifications.

[0023] A guide plate 13 is provided on the outer side of the mounting bushing of the grinding mounting seat 4. A guide groove is provided on the guide plate 13. A grinding seat is slidably arranged in the guide groove. The grinding seat is connected to the adjusting shaft 3 provided on the guide plate 13.

[0024] The grinding mounting base 4 is used to fix and support the guide plates 13. There are four guide plates 13. The grinding base can grind from four directions, which can effectively improve the grinding efficiency. The mounting bushing is fixed in the position of the guide plate 13 to ensure its stable installation on the grinding mounting base 4, and plays a guiding and supporting role.

[0025] The guide plate 13 is equipped with a guide groove, which is the guide rail for the sliding movement of the grinding seat; by cooperating with the adjusting shaft 3, it can achieve precise control of the position of the grinding seat.

[0026] The grinding base includes a grinding wheel 6, a driven synchronous pulley 12, and an intermediate support 5. The intermediate support 5 is slidably disposed in a guide groove. A rotating shaft is sleeved in the through hole of the intermediate support 5. One end of the shaft is provided with the driven synchronous pulley 12, and the other end is sleeved with the grinding wheel 6.

[0027] The intermediate support 5 fixes the rotating shaft and carries the driven synchronous pulley 12 and the grinding wheel 6; it slides in the guide groove and is connected to the adjusting shaft 3 to realize the feeding action of the grinding seat.

[0028] The rotating shaft supports the grinding wheel and the driven synchronous pulley 12, and drives them to rotate synchronously. The driven synchronous pulley 12 at its end receives power from the drive motor 8 and transmits the rotational motion to the grinding wheel 6; and performs actual grinding work on the inner ring groove of the bearing.

[0029] Furthermore, a drive motor 8 is provided on the lower surface of the guide groove 10, and an active synchronous pulley 7 is provided at the output end of the drive motor 8. The active synchronous pulley 7 is connected to the synchronous pulley provided in the grinding seat through a synchronous belt.

[0030] The drive motor 8 is the power source for the entire grinding device. It drives the active synchronous pulley 7 to rotate and transmits the power to the driven synchronous pulley 12 through the synchronous belt transmission system, thereby driving the grinding wheel 6 to rotate at high speed.

[0031] Furthermore, a motor mounting base 11 is provided on the lower surface of the guide groove 10, and the motor mounting base 11 is connected to the drive motor 8 by fasteners.

[0032] Furthermore, the motor mounting base 11 is formed by hinged two mounting plates, and the two folded mounting plates are connected by a connecting shaft.

[0033] The motor mounting bracket 11 fixes the drive motor 8, ensuring stable operation of the drive system and reducing power transmission instability caused by vibration. One mounting plate is used to fix it to the bottom of the guide slot 10, and the other is used to install the drive motor 8. The hinged structure facilitates the later maintenance of the drive motor 8 and the adjustment of the tension between the synchronous belts.

[0034] Furthermore, a driven gear 14 is sleeved on the outer side of the rotating support shaft 2, and a driving rotating component 15 is also provided on the pad seat 1 on the guide groove component 10. The output end of the driving rotating component 15 is also provided with a driving gear, and the driving gear and the driven gear 14 mesh with each other.

[0035] The rotating component 15 drives the drive gear to rotate, which in turn meshes with the driven gear 14, thereby driving the rotating support shaft 2 to rotate, thus enabling the inner ring of the bearing placed on the rotating support shaft 2 to rotate, and thus achieving full grinding of the inner ring of the bearing.

[0036] Furthermore, the grinding wheel 6 adopts a replaceable structure and is installed on the rotating shaft by threaded connection or snap-fit ​​method.

[0037] Furthermore, the adjusting shaft 3 is a threaded shaft, and the grinding seat is connected to the adjusting shaft 3 through a threaded pair. Rotating the adjusting shaft 3 can achieve precise position adjustment of the grinding seat along the guide groove.

[0038] In use: Fit the inner ring of the bearing to be processed onto the rotating support shaft 2 and fix it with a self-centering chuck. Adjust the position of the inner ring so that it is within the effective working range of the grinding wheel 6. Install the appropriate grinding wheel 6 onto one end of the rotating shaft using threads or snap-fit. Install the driven synchronous pulley 12 onto the other end of the rotating shaft and secure it with a lock nut. Embed the intermediate support 5, along with the rotating shaft and the grinding wheel 6, into the guide groove on the guide plate 13, ensuring smooth and unobstructed sliding. Slowly rotate the adjusting shaft 3 to push the grinding seat along the guide groove towards the inner ring of the bearing, beginning micro-feed grinding. Turn on the drive motor 8 to make the grinding wheel 6 rotate at high speed. Start the drive rotating component 15 to slowly rotate the inner ring of the bearing. Complete the full grinding process.

[0039] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
