Description

Technical Field

[0001] This utility model relates to the field of bushing processing technology, and more specifically to a bushing inner diameter grinding device. Background Technology

[0002] Bushings are commonly assembled on mechanical parts, mainly to reduce friction between parts and to provide a certain guiding function, so as to ensure that the mechanical parts can operate smoothly during operation.

[0003] Bushings are usually cylindrical, and their processing methods include rolling and welding or mechanical chip forming, to ensure that the size and accuracy of the bushing are within the qualified range, and to ensure high assembly accuracy with other mechanical parts.

[0004] During the production of bushings, when the bushings are initially formed into a cylindrical shape, their inner diameter needs to be ground to improve the assembly accuracy of the bushings. Workers often use sandpaper to grind the inner diameter of the bushings. However, for some bushings that are too long or have a small inner diameter, it is difficult to reach in with your hands, resulting in some areas not being ground properly, which in turn affects the production quality of the bushings.

[0029] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0030] like Figure 1-4 As shown, a bushing inner diameter grinding device includes a bushing body 3, and further includes:

[0031] The base plate 1 is provided with a support frame 7 and an electric push rod 6 is provided on the support frame 7.

[0032] The drive base 5 is slidably mounted on the support frame 7 and engages with the output end of the electric push rod 6. The drive base 5 is equipped with a motor 56.

[0033] Grinding unit 4 is mounted on drive base 5 and includes rotating rod 41 and support member 43 mounted on rotating rod 41. Grinding disc 42 is mounted on support member 43. Rotating rod 41 is engaged with output end of motor 56.

[0034] Clamping plate 2 is set on base plate 1. Clamping plate 2 is provided with a shim 22 for clamping bushing body 3 so that bushing body 3 is fixed directly below grinding disc 42.

[0035] Specifically, the bushing body 3 is placed on the shim block 22 to fix the bushing body 3 away from the clamping plate 2, thereby adapting to the grinding unit 4 for grinding. Then, the electric push rod 6 controls the drive seat 5 to slide down along the support frame 7 so that the grinding disc 42 contacts the inner wall of the bushing body 3. Subsequently, under the linkage of the motor 56 controlling the rotation of the rotating rod 41 and the electric push rod 6, the grinding disc 42 is located at the inner diameter of the bushing body 3 for grinding, thereby improving the grinding efficiency and effect of the bushing body 3.

[0036] As a further embodiment of this utility model, the support member 43 includes a fixing block 436, a turntable 431, and a slider 437 disposed on the turntable 431. A guide cylinder 433 is disposed on the slider 437, and a connecting rod 434 rotatably connected to the grinding disc 42 is slidably disposed on the guide cylinder 433. A spring 432 is disposed between the connecting rod 434 and the guide cylinder 433. The fixing block 436, the turntable 431, and the slider 437 are all disposed on the rotating rod 41. A support rod 435 rotatably connected to the grinding disc 42 is disposed on the fixing block 436. When the bushing body 3 is fixed to the clamping plate 2, the turntable 431 is rotated to control the slider 437 to slide downward in the vertical direction. At this time, the support rod 435 will extend outward under the sliding of the slider 437, and the connecting rod 434 will also extend outward under the elastic push of the spring 432, so that the two grinding discs 42 are tapered with a smaller bottom and a larger top, so as to adapt to bushing bodies 3 with different inner diameters.

[0037] As a further embodiment of this utility model, one end of the rotating rod 41 is provided with a three-joint 441, and the three-joint 441 is provided with a conveying pipe 442 that cooperates with the support rod 435. The grinding disc 42 is provided with a support block 443 that communicates with the conveying pipe 442, and the support block 443 is provided with a feeding cylinder 444. The grinding agent at the center of the rotating rod 41 is received by the three-joint 441, and the grinding agent is pushed into the conveying pipe 442 by pressure, and then along the conveying pipe 442 to the feeding cylinder 444. The grinding agent is evenly coated onto the inner wall of the bushing body 3 through the feeding cylinder 444, thereby improving the grinding effect on the bushing body 3.

[0038] As a further embodiment of this utility model, a window 4351 is provided on the support rod 435, and the conveying pipe 442 is fixed to the window 4351 by a cable tie, thereby limiting the conveying pipe 442 and reducing the phenomenon of the conveying pipe 442 swinging around during the grinding process.

[0039] As a further embodiment provided by this utility model, the rotating rod 41 is provided with a threaded portion 411 and a sliding groove portion 412. The turntable 431 is threadedly connected to the threaded portion 411, while the slider 437 slides on the sliding groove portion 412. The fixing block 436 is fixedly connected to the end of the rotating rod 41. During the rotation of the turntable 431 on the threaded portion 411, the slider 437 is driven to slide downward along the sliding groove portion 412, thereby controlling the grinding disc 42 to extend outward, thereby adapting to the bushing body 3 with different inner diameters. The slider 437 does not contact the threaded portion 411.

[0040] As a further embodiment provided by this utility model, a first pulley 52 and a second pulley 53 are rotatably mounted on the drive base 5. A synchronous belt 51 is provided between the first pulley 52 and the second pulley 53. The first pulley 52 is engaged with the rotating rod 41, while the second pulley 53 is engaged with the output shaft of the motor 56. The number of teeth on the second pulley 53 is greater than the number of teeth on the first pulley 52, thereby accelerating the movement and increasing the rotation speed of the rotating rod 41. The model of the motor 56 is MHMF042L1U4-1116.

[0041] As a further embodiment of this utility model, the drive seat 5 is provided with a connector 55 that cooperates with the electric push rod 6. The connector 55 is threadedly connected to the electric push rod 6. During the grinding process, the electric push rod 6 is used to control the drive seat 5 to move closer to or away from the bushing body 3.

[0042] As a further embodiment of this utility model, the drive seat 5 is provided with an abrasive connector 57, which is connected to the rotating rod 41. The abrasive connector 57 receives the abrasive required during the abrasive process. The abrasive can be polishing paste, which is poured into the shaft of the rotating rod 41 through the abrasive connector 57.

[0043] As a further embodiment of this utility model, the shim block 22 is provided with a first bolt 21 and a second bolt 23. The first bolt 21 abuts against the outer wall of the bushing body 3, while the second bolt 23 is grounded with the clamping plate 2. The first bolt 21 is used to support and fix the bushing body 3, while the second bolt 23 is used to support the shim block 22. At least four sets of shim blocks 22 are provided, and the four sets slide on the clamping plate 2 to accommodate bushing bodies 3 of different specifications. Furthermore, the bushing body 3 is raised by the shim block 22, so that the bushing body 3 is away from the clamping plate 2, thereby adapting to the grinding process of the grinding unit 4.

[0044] As a further embodiment of this utility model, a slide rail 71 is provided on the support frame 7, and the drive seat 5 is slidably connected to the slide rail 71. The slide rail 71 is symmetrically arranged on the support frame 7.
