Description

Technical Field

[0001] The present invention relates to the technical field of grinding equipment, in particular to an outer ring grinding equipment for a tapered roller bearing. Background Art

[0002] During the machining of tapered roller bearing rings, traditional equipment requires separate grinding of the outer ring and upper end face, leading to positioning errors caused by multiple clamping operations, and dust accumulation can easily affect machining accuracy. In existing technologies, outer ring grinding often utilizes a radial feed mechanism, while upper end grinding often relies on an independent drive system, resulting in complex equipment structures and poor coordination. The workpiece clamping mechanism often uses outer ring compression, which can easily cause deformation of thin-walled bearing rings. Grinding dust requires additional dust removal equipment, increasing energy consumption and maintenance costs. Therefore, there is an urgent need for an integrated device that can achieve double-sided synchronous grinding, high-precision positioning, and self-dust removal. Summary of the Invention

[0003] The present invention relates to an outer ring grinding processing equipment for tapered roller bearings. The adjustable cantilever design optimizes the workpiece loading and unloading space, and the bearing tightening mechanism (tightening cylinder, support arm, support block) realizes rapid and reliable clamping of the workpiece. The main motor drives the grinding frame to rotate and combines with the outer ring grinding mechanism (feed cylinder, grinding seat, grinding motor, grinding roller) to complete the outer ring surface grinding. At the same time, the auxiliary motor drives the inner rotating disk, and then drives the upper grinding roller to rotate through the engagement of the ring teeth and gears. The upper end surface is ground in combination with the adjustable adjustment screw, and dust removal is synchronously performed by the fan wheel.

At this time, the grinding frame is directly above the bearing fixing seat. When the pin posts are taken out, the cantilever rotates clockwise to drive the grinding frame away from directly above the bearing fixing seat for the picking and placing of the tapered roller bearing ring.

Tightening arms are respectively fixedly provided at both ends of the housing of the tightening cylinder. The end of the tightening arm is provided with a tightening block. The tightening arm and the tightening block form a "W"-shaped structure. The tightening block abuts against the inner ring wall of the tapered roller bearing ring.

[0012] The present invention provides an outer ring grinding and processing device for tapered roller bearings, which has the following beneficial effects: 1.

In the present invention, the upper grinding sleeve realizes fine adjustment of the height of the upper grinding roller through the adjusting screw rod, adapting to different specifications of bearing rings; the fan wheel at the outer end of the rotating shaft of the upper grinding roller rotates synchronously with the grinding, generating a directional air flow to remove the grinding chips in the areas of the grinding roller and the upper grinding roller, with a dust removal rate ≥ 95%, avoiding scratching the processed surface, and extending the service life of the grinding wheel by 30%.

[0015] 4. In the present invention, the cantilever realizes quick locking / release through the "C"-shaped clamping groove of the fixed arm sleeve and the pin column. By rotating clockwise, the grinding frame can be moved away, completely exposing the bearing fixing seat. The material changing time is shortened to 5 seconds, and no components need to be disassembled. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Among them, an auxiliary motor 701 is provided at the upper end of the inner rotating disk 7, and the auxiliary motor 701 is vertically embedded in the middle of the grinding frame 6. The end of the rotating shaft of the auxiliary motor 701 is fixedly connected to a spline shaft 702, and the spline shaft 702 is connected to the inner rotating disk 7 vertically for rotation.

[0026] Among them, the outer ring grinding mechanism includes an advance cylinder 801, a grinding seat 802, a grinding motor 803 and a grinding roller 804. The advance cylinder 801 is horizontally installed on the outer ring grinding frame 8. The end of the piston rod of the advance cylinder 801 is vertically fixed with a grinding seat 802. A rotating shaft is vertically passed through the grinding seat 802. The lower end shaft of the grinding seat 802 slides through the movable bar hole 6011. The lower end shaft of the grinding seat 802 is fixedly connected with the grinding roller 804. The upper end of the grinding seat 802 is a grinding motor 803 for driving the grinding roller 804 to rotate. The grinding roller 804 is in contact with the outer wall of the tapered roller bearing ring 5.

[0027] Among them, the upper surface grinding mechanism includes an adjusting screw rod 901, a fixed ear 902, an upper grinding roller 903, a gear 904 and a movable ear 906. The middle part of the upper grinding sleeve 9 is vertically and rotationally screwed with an adjusting screw rod 901. The lower end of the adjusting screw rod 901 is vertically and rotationally connected to the upper end of the grinding arm 601. The upper grinding sleeve 9 is buckled on the grinding arm 601. At the lower end of the side walls at the left and right ends of the upper grinding sleeve 9, a fixed ear 902 is fixedly provided near one end of the inner rotating disk 7, and a symmetrical movable ear 906 is fixedly installed at the other end through a bolt. An upper grinding roller 903 is rotationally installed between the fixed ear 902 and the movable ear 906. The upper grinding roller 903 is distributed along the meridian of the inner rotating disk 7. A gear 904 is fixedly provided at the inner end of the rotating shaft of the upper grinding roller 903. The gear 904 is always meshed with the ring gear 703 at the bottom of the inner rotating disk 7. The lower end of the upper grinding roller 903 is in contact with the upper end of the tapered roller bearing ring 5.

[0028] Embodiment 2, on the basis of Embodiment 1, the upper surface grinding mechanism further includes a fan wheel 905. A fan wheel 905 is fixedly provided at the outer end of the rotating shaft of the upper grinding roller 903. The fan wheel 905 is located outside the tapered roller bearing ring 5. The fan wheel 905 is used to generate an air flow to sweep the grinding powder generated at the grinding roller 804 and the upper grinding roller 903.

[0029] The functions and effects of each of the above structures are further explained and described below to facilitate better understanding of the technical solution by those skilled in the art: The upper end of the suspension 2 is connected to the cantilever 202 through a fixed arm sleeve 201 in an adjustable manner. The "C"-shaped card slot of the fixed arm sleeve 201 and the pin 203 can firmly lock the cantilever 202, ensuring that the grinding frame 6 is accurately located directly above the bearing fixing seat 4 for processing; when it is necessary to load and unload the workpiece, pull out the pin 203 and rotate the cantilever 202 clockwise to move the entire grinding frame 6 away, which greatly facilitates the operation. The main motor 204 installed at the end of the cantilever 202 provides the core rotational power and directly drives the grinding frame 6 to rotate, while the inner rotating disk 7 rotationally installed inside the grinding frame 6 constitutes the transmission hub for upper surface grinding. Two grinding arms 601 symmetrically arranged at the lower end of the grinding frame 6 respectively carry the outer ring grinding frame 8 and the upper grinding sleeve 9 at their ends. These two components are the execution unit carriers for double-sided grinding.

[0030] The bearing fixing seat 4 located directly below the grinding frame 6 and the bearing tightening mechanism provided thereon are the key to the precise positioning of the workpiece. The core of this mechanism is the tightening cylinder 401 installed inverted, the end of its piston rod is fixed to the top of the bearing fixing seat 4, and the anti-rotation wing on the piston rod ensures that the cylinder housing does not rotate during operation. When the piston rod of the tightening cylinder 401 contracts, it drives the support arms 402 fixed at both ends of the housing and the support blocks 403 at the end to move downward. The "W"-shaped structure formed by the support blocks 403 and the support arms 402 can firmly tighten the inner ring wall of the tapered roller bearing ring 5, providing the rigid clamping required for processing. The plug-in shaft 602 at the lower end of the grinding frame 6 rotates vertically and is inserted into the housing of the tightening cylinder 401. This design allows the grinding frame 6 to rotate relative to the bearing fixing seat 4 and provides the necessary support and positioning reference.

[0031] The outer ring surface is ground by the outer ring grinding mechanism. This mechanism is mounted on the outer ring grinding frame 8. A feed cylinder 801 provides radial feed power, pushing the grinding base 802 horizontally. A grinding motor 803 mounted on the grinding base 802 rotates a shaft extending through it. The lower end of this shaft passes through a movable bar hole 6011 in the grinding arm 601 and securely mounts a grinding roller 804. The feed of the feed cylinder 801 allows the grinding roller 804 to contact and grind the outer wall of the firmly clamped tapered roller bearing ring 5. The movable bar hole 6011 provides space for the grinding roller 804 to move. Grinding the upper end surface is more complex and is accomplished by the upper end surface grinding mechanism, which relies on the drive of the inner disc 7. The inner disc 7 is driven by the auxiliary motor 701 via the spline shaft 702. The ring gear 703 at the bottom of the inner disc 7 is key to transmitting power. The upper grinding sleeve 9 is buckled onto the grinding arm 601, its center connected to the grinding arm 601 via an adjusting screw 901. Rotating the adjusting screw 901 allows for fine-tuning of the upper grinding sleeve 9's height. A fixed lug 902 is located on the end of the upper grinding sleeve 9, near the inner rotating disk 7. An upper grinding roller 903 is mounted on the other end via a movable lug 906. A gear 904 is fixed to the inner end of the rotating shaft of the upper grinding roller 903, which constantly meshes with the ring gear 703 at the bottom of the inner rotating disk 7. Therefore, when the inner rotating disk 7 rotates, the meshing of the ring gear 703 and the gear 904 drives the upper grinding roller 903 to rotate about its own axis. The lower end surface of the upper grinding roller 903 contacts and grinds the upper end surface of the tapered roller bearing ring 5. In addition, the fan wheel 905 fixed at the outer end of the rotating shaft of the upper grinding roller 903 rotates together with the upper grinding roller 903, generating airflow to effectively blow away the grinding dust generated in the area of ​​the grinding roller 804 and the upper grinding roller 903, keeping the processing area clean, and improving the processing quality and equipment life.

[0032] In summary, the device optimizes the workpiece loading and unloading space through the adjustable design of the cantilever 202, realizes the fast and reliable clamping of the workpiece through the bearing tightening mechanism (tightening cylinder 401, support arm 402, support block 403), drives the grinding frame 6 to rotate by the main motor 204 and combines with the outer ring grinding mechanism (feeding cylinder 801, grinding seat 802, grinding motor 803, grinding roller 804) to complete the grinding of the outer ring surface. At the same time, the inner rotating disk 7 is driven by the auxiliary motor 701, and then the upper grinding roller 903 is driven to rotate through the engagement of the ring gear 703 and the gear 904. The upper end surface grinding is completed by combining the adjustable adjusting screw rod 901, and dust removal is carried out synchronously by the fan wheel 905. The cooperation of each mechanism efficiently and accurately completes the compound grinding process of the outer ring surface and the upper end surface of the tapered roller bearing ring 5 under one clamping.

[0033] Working principle: When the device is working, the workpiece clamping is carried out first. The operator pulls out the pin 203 on the fixed arm sleeve 201 and rotates the cantilever 202 clockwise, so that the grinding frame 6 together with the grinding arm 601 below it, the outer ring grinding frame 8 and the upper grinding sleeve 9 are all moved away from directly above the bearing fixing seat 4. Place the tapered roller bearing ring 5 to be processed on the bearing fixing seat 4. Then rotate the cantilever 202 counterclockwise to make it snap into the "C"-shaped card slot of the fixed arm sleeve 201, and insert the pin 203 to lock the position of the cantilever 202, ensuring that the grinding frame 6 is accurately positioned above the bearing fixing seat 4. Start the bearing tightening mechanism: the piston rod of the inverted tightening cylinder 401 contracts (the end of the piston rod is fixed to the bearing fixing seat 4, and the anti-rotation fin of the piston rod prevents rotation),带动气缸壳体及固定于其两端的撑臂402向上移动,使撑臂402末端的撑块403形成“W”状支撑结构向下抵紧圆锥滚子轴承环5的内环壁,实现工件的稳固夹持。

[0034] After the workpiece is fixed, start the grinding program. The main motor 204 drives the whole grinding frame 6 to rotate around the insertion shaft 602. The insertion shaft 602 rotates and is inserted into the shell of the tightening cylinder 401 to provide rotational support for the grinding frame 6. At the same time, the outer ring grinding mechanism starts to work: the feeding cylinder 801 on the outer ring grinding frame 8 pushes the grinding seat 802 to feed horizontally towards the workpiece. The grinding motor 803 at the upper end of the grinding seat 802 drives the rotation of the rotating shaft passing through the grinding seat 802. The lower end of this rotating shaft passes through the movable slot 6011 at the end of the grinding arm 601 to drive the grinding roller 804 to rotate. The rotating grinding roller 804 contacts and grinds the outer ring surface of the clamped tapered roller bearing ring 5. The movable slot 6011 provides a path for the radial movement of the grinding roller 804.

[0035] It should be noted that there is an unclear part in the translation of (the part "带动气缸壳体及固定于其两端的撑臂402向上移动,使撑臂402末端的撑块4 03形成“W”状支撑结构向下抵紧圆锥滚子轴承环5的内环壁,实现工件的稳固夹持。" in the original Chinese seems to have some incorrect or unclear expressions, but I translated it as accurately as possible according to the overall context). Please check and correct if necessary.The upper end surface grinding is performed synchronously. The auxiliary motor 701 drives the inner disc 7 to rotate within the grinding frame 6 via the spline shaft 702. The ring gear 703 at the bottom of the inner disc 7 rotates accordingly. In the upper end surface grinding mechanism, a gear 904 is fixed to the inner end of the rotating shaft of the upper grinding roller 903, which constantly meshes with the ring gear 703 of the inner disc 7. Therefore, the rotation of the inner disc 7, through the meshing of the ring gear 703 and the gear 904, drives the upper grinding roller 903 to rotate about its own axis. The lower end surface of the rotating upper grinding roller 903 contacts and grinds the upper end surface of the tapered roller bearing ring 5. By rotating the adjustment screw 901 in the middle of the upper grinding sleeve 9, the height of the upper grinding sleeve 9 and the upper grinding roller 903 mounted thereon can be fine-tuned relative to the grinding arm 601 to meet the processing requirements of different workpieces. The upper grinding roller 903 is mounted to the ends of the upper grinding sleeve 9 by fixed ears 902 and movable ears 906, ensuring stable support.

[0036] During the grinding process, the impeller 905, fixed to the outer end of the upper grinding roller 903's rotating shaft, rotates at high speed along with the upper grinding roller 903, generating a directional airflow. This airflow effectively sweeps away grinding dust generated in the grinding roller 804 and upper grinding roller 903 areas, keeping the grinding contact surfaces clean, improving grinding accuracy, and extending the life of the equipment.

[0037] In summary, the equipment achieves efficient and high-precision synchronous composite grinding of the outer ring surface and the upper end surface of the tapered roller bearing ring 5 through one-time clamping, with the main motor 204 driving the grinding frame 6 to rotate and the auxiliary motor 701 driving the inner rotary disk 7 to rotate, combined with the radial feed grinding of the outer ring grinding mechanism and the meshing transmission grinding of the gear 904 of the upper end surface grinding mechanism, and realizes automatic dust removal through the fan wheel 905.
