[0025] Please see Figure 1 This utility model discloses a boring and milling shaft honing equipment for honing the surface of a shaft 100 to be honed, thereby improving the machining accuracy and surface accuracy of the shaft.

[0026] The boring and milling shaft honing equipment includes a bed 10, a drive structure 20, a chuck 30, a tailstock 40, a honing sleeve 50, a moving component 60, and a limit block 70.

[0027] Please continue reading. Figure 2 The bed 10 includes a main body 11, a support column 12, and a control box 14. The main body 11 is provided with a slide rail 110 for moving the moving component 60. The support column 12 is fixed to the bottom of the main body 11 to support the main body 11. The control box 14 is fixed to one end of the main body 11 and is used to control the rotation of the honing shaft 100.

[0028] The drive structure 20 is used to drive the moving assembly 60 to move, thereby causing the honing sleeve 50 to move axially along the shaft 100 to be honed. Specifically, the drive structure 20 includes a mounting base 21, a drive member 22, a first transmission member 23, and a second transmission member 24. The mounting base 21 is fixed to the main body 11, and the drive member 22 is fixed to the mounting base 21. The drive member 22 drives the moving assembly 60 to move through the first transmission member 23 and the second transmission member 24. In this embodiment, the drive member 22 is a motor, the first transmission member 23 is a pulley, and the second transmission member 24 is a lead screw. The motor drives the pulley to rotate through a belt. The pulley is fixedly connected to the end of the lead screw, and the pulley drives the lead screw to rotate. The lead screw converts the rotation into linear movement, thereby causing the slide box 61 to move along the length direction of the shaft 100 to be honed.

[0029] The chuck 30 is fixed to the control box 14. The chuck 30 is used to clamp the shaft to be honed 100 and drive the shaft to be honed 100 to rotate.

[0030] The tailstock 40 is mounted on the main body 11 and is used to hold the honing shaft 100.

[0031] Please continue reading. Figure 3 as well as Figure 4 The honing sleeve 50 includes an inner sleeve 51, an outer sleeve 52, a locking nut 53, and a loosening nut 54. The inner surface of the inner sleeve 51 is cylindrical and serves as the honing surface. The outer surface of the inner sleeve 51 is tapered to allow the inner sleeve 51 to contract, with a taper of 1:10.

[0032] Specifically, the inner sleeve 51 includes a body 510 and a first connecting end 511 and a second connecting end 512 located at both ends of the body 510. The outer surfaces of both the first connecting end 511 and the second connecting end 512 are provided with external threads. The surface of the body 510 forms the outer wall 513 of the inner sleeve 51. The outer wall 513 is conical and has grooves 5130. These grooves 5130 allow the inner sleeve 51 to contract. The grooves 5130 are straight, and multiple grooves 5130 are evenly distributed on the outer wall 513. The inner surface of the body 510 is cylindrical and has a chip removal groove 514 extending from one end of the inner sleeve 51 to the other. The chip removal groove 514 is used to remove chips generated during honing and also promotes the contraction or opening of the inner sleeve 51. The chip removal groove 514 is staggered from the grooves 5130 to prevent the inner sleeve 51 from having insufficient structural strength and being easily damaged.

[0033] The inner wall 520 of the outer sleeve 52 is a conical surface, with the same taper as the outer wall 513 of the inner sleeve 51. The outer surface of the outer sleeve 52 is cylindrical, and the outer sleeve 52 is also provided with a connecting hole 521 for connecting the outer sleeve 52 to the connecting rod 63.

[0034] The locking nut 53 is provided with a first internal thread 530. The locking nut 53 is rotatably installed on the external thread of the second connecting end 512 through the first internal thread 530. When the locking nut 53 rotates, it abuts against the outer sleeve 52, causing the outer sleeve 52 to move axially relative to the inner sleeve 51. Since both the outer sleeve 52 and the inner sleeve 51 are provided with tapered surfaces, the outer sleeve 52 will compress the inner sleeve 51 when it moves relative to the inner sleeve 51, thus adjusting the inner hole size of the inner sleeve 51.

[0035] The loosening nut 54 is provided with a second internal thread 540, and the loosening nut 54 is rotatably mounted on the first connecting end 511 through the second internal thread 540. When the loosening nut 54 rotates, it abuts against the outer sleeve 52, causing the outer sleeve 52 to move axially in the opposite direction relative to the inner sleeve 51, causing the outer sleeve 52 to move in the opposite direction relative to the inner sleeve 51, and the inner sleeve 51 to expand.

[0036] The moving component 60 includes a slide box 61, a connecting frame 62, and a connecting rod 63. The slide box 61 is slidably mounted on the slide rail 110, the connecting frame 62 is fixed to the top of the slide box 61, and one end of the connecting rod 63 is installed in the connecting hole 521 of the outer sleeve 52, and the other end is installed in the connecting frame 62.

[0037] When using a boring and milling spindle honing machine, first, the honing sleeve 50 is placed on the surface of the spindle 100 to be honed, and then the spindle 100 to be honed is clamped between the chuck 30 and the tailstock 40. One end of the connecting rod 63 of the moving component 60 is installed in the connecting hole 521 of the outer sleeve 52, and the other end is installed in the connecting bracket 62. The bed 10 drives the spindle 100 to be honed to rotate, and the honing sleeve 50 hones the surface of the spindle 100. After honing at one position, the drive structure 20 drives the honing sleeve 50 to move axially through the moving component 60 until the surface of the spindle 100 to be honed is completely honed. During the honing process, when it is necessary to adjust the inner diameter of the honing shaft 100, the locking nut 53 is rotated. When the locking nut 53 rotates, it abuts against the outer sleeve 52, causing the outer sleeve 52 to move axially relative to the inner sleeve 51. Since both the outer sleeve 52 and the inner sleeve 51 are provided with tapered surfaces, the outer sleeve 52 will compress the inner sleeve 51 when it moves relative to the inner sleeve 51, thus adjusting the inner diameter of the inner sleeve 51.

[0038] With the above design, the shrinkage of the honing sleeve 50 can be adjusted simply by rotating the locking nut 53. The adjustment range is controllable, simple, and the inner hole shrinkage dimension is accurate.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
