DETAILED DESCRIPTION

[0032] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] See also Figure 1-7 , the present invention provides a tapered roller bearing ring primary grinding and fine grinding integrated machine, comprising a base 1;

[0034] A conveying mechanism 2, the conveying mechanism 2 is movably arranged on the base 1 and is used to convey the bearing ring 100;

[0035] A first oilstone swing mechanism 3, which is fixedly arranged on one side of the conveying device 2 and symmetrically arranged at the input end and the output end of the conveying device 2;

[0036] A positioning device 4, wherein the positioning device 4 is fixedly arranged below the first oilstone swing mechanism 3;

[0038] The pushing device 6 is arranged at one side of the conveying device 2 and is used to transport the bearing ring 100 from the conveying device 2 to the positioning device 4 .

[0039] In the above structure, if Figure 2 In the embodiment 1, two sets of symmetrically arranged first oilstone swing mechanisms are arranged on the side of the transmission mechanism. The first oilstone swing mechanism near the input end of the transmission mechanism uses an oilstone with a low friction coefficient to initially grind the bearing rings, and the first oilstone swing mechanism near the output end of the transmission mechanism uses an oilstone with a high friction coefficient to finely grind the bearing rings.

[0040] When the staff starts the conveying mechanism, the bearing ring placed on it is transported to the specified position, and the pushing device pushes the bearing ring to the positioning device. After the clamping mechanism presses and fixes the bearing ring, the first oilstone swing mechanism with an oilstone with a low friction coefficient is used to initially grind the bearing ring. After the initial grinding is completed, the pushing device pushes the bearing ring back to the conveying mechanism. After the bearing ring is transported to the specified position again by the conveying mechanism, the pushing device pushes the bearing ring to the positioning device. After the clamping mechanism presses and fixes the bearing ring, the first oilstone swing mechanism with an oilstone with a high friction coefficient is used to fine-grind the bearing ring. The conveying, initial grinding and fine grinding functions are integrated into one, reducing the space required for the equipment.

[0041] Specifically, a protective shell 10 is provided on the base 1, and the protective shell can prevent the entry of external dust and can also block the ejection and flying of waste chips when grinding the bearing ring.

[0042] Specifically, a discharge slide 20 is fixedly provided at the output end of the conveying mechanism 2, and a collecting device 101 for collecting the bearing ring 100 is provided at the output end of the discharge slide 20, and the discharge slide has a guiding effect on the bearing ring.

[0043] Specifically, the transmission mechanism 2 includes a transmission frame 21 movably arranged on the base 1, a rotating gear 22 rotatably arranged at both ends of the transmission frame 21, and a synchronous belt 23 used in conjunction with the rotating gear 22. The use of the rotating gear and the synchronous belt can achieve high-speed transmission and high-torque transmission. At the same time, the rotating gear and the synchronous belt are precision transmission tools, and their combined use can ensure the stability and accuracy of the transmission.

[0044] Specifically, a height adjustment device 24 for adjusting the overall height of the conveying mechanism 2 is provided on one side of the conveying frame 21. The height adjustment device can adjust the height of the conveying mechanism according to workpieces of different heights and thicknesses, thereby increasing the application range of the conveying mechanism.

[0045] Specifically, the first oilstone swing mechanism 3 includes a bracket 30 fixedly arranged on the base 1, a first support plate 31 movably arranged on the bracket 30, a second support plate 32 movably arranged on the first support plate 31, a first transmission device 33 for driving the second support plate 32 to perform a linear reciprocating motion up and down on the first support plate 31, a second transmission device 34 arranged on the second support plate 32, a swing device 35 connected to the second transmission device 34 at one end, and an oilstone unit 36 ​​arranged at the bottom end of the swing device 35, the second transmission device 34 drives the oilstone unit 36 ​​to perform a reciprocating motion up and down through the swing device 35, the first oilstone swing mechanism cooperates with the second transmission device to swing and oscillate the oilstone unit through the swing device, the swing device plays a positioning role in the overall oilstone friction processing, and can improve the overall processing quality.

[0046] Specifically, the bracket 30 includes an arc-shaped guide groove 300 recessed on one side of the bracket 30 and a screw nut device 301 for driving the first support plate 31 to move on the arc-shaped guide groove 300. The use of the arc-shaped guide groove allows the first support plate to be accurately positioned when the angle changes without positional displacement. The use of the screw nut device as a transmission device for the first support plate can ensure accuracy when the angle changes, and at the same time, the transmission efficiency of the screw nut is higher.

[0047] Specifically, the clamping mechanism 5 includes a clamping frame 50 fixedly arranged on the base 1, an axle seat 51 fixedly arranged on the clamping frame 50, an axle 52 rotatably supported on the axle seat 51, support blocks 53 sleeved on both ends of the axle 52, clamps 54 symmetrically arranged on the support blocks 53 on both sides, and a cylinder 55 whose ends are hinged to the support blocks 53, the clamps 54 are located above the positioning device 4, and are used to clamp the bearing ring 100 to the positioning device 4, the clamping mechanism uses a clamping structure of double clamps controlled by double cylinders to prevent the bearing ring from having an uneven end surface due to the clamping of a single-sided clamp.

[0048] Specifically, the pushing device 6 includes a first guide rail 60 fixedly arranged on the side of the conveying mechanism 2, a first slider 61 movably arranged on the first guide rail 60, a first limit block 62 fixedly arranged on the first slider 61, a second limit block 63 movably arranged on the first slider 61, a pushing arm 64 movably arranged on the conveying mechanism 2, and a driving device 65 for driving the pushing arm 64 to move from above the conveying mechanism 2 to above the positioning device 4. One end of the first guide rail 60 corresponds to the position of the positioning device 4, and the bearing ring is transported to the output end by the conveying mechanism. When the conveying mechanism is transported to the position of the first limit block, the first limit block blocks the bearing ring and then the second limit block pops out, so that the bearing ring is blocked in the middle by the first limit block and the second limit block, and the first slider moves on the first guide rail, thereby driving the first limit block and the second limit block to move synchronously, and the bearing ring moves to the specified position synchronously, and the driving device drives the pushing arm with the bearing ring to the positioning device, and uses the pushing device to push the bearing ring to the specified position, which can increase the overall accuracy, and at the same time, using the first limit block and the second limit block to limit the positions of the two ends of the bearing ring can prevent the bearing ring from shifting when it is displaced.

[0049] Specifically, a second oilstone swing mechanism 7 is provided between the first oilstone swing mechanism 3 , and the second oilstone swing mechanism 7 is used to grind the rib of the bearing ring 100 . The independent provision of the second oilstone swing mechanism to grind the rib can make the rib more precise.

[0050] like Figure 3 The difference between the embodiment 2 and the embodiment 1 is that in the embodiment 2, two symmetrically arranged second oilstone swing mechanisms are added to the two first oilstone swing mechanisms, and a conventional clamping mechanism is used instead of a double cylinder to control the clamping structure of the double clamps.

[0051] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
