Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of cutting and grinding material supporting mechanisms of shaft parts. BACKGROUND

[0002] Shaft parts are one of the typical parts often encountered in hardware fittings, which are mainly used to support transmission parts, transmit torque and bear load. Micro shaft is a kind of shaft parts, which is relatively small and high-precision. Micro shaft can also be called precision shaft, small shaft, shaft core, rotor shaft, pin, rivet, guide rod, etc. Micro shaft is used in many industries, such as the rotating shaft in motor, printer, copying machine and scanner. When shaft parts are processed by cutting and grinding, shaft parts need to be axially positioned by cutting and grinding positioning mechanism. However, the existing cutting and grinding material supporting mechanism has the defects of complex structure design and inconvenient operation. SUMMARY

[0003] The utility model aims at overcoming the defects of prior art, and provides a kind of cutting and grinding material supporting mechanisms of shaft parts, which has simple structure, stable and reliable performance and convenient operation.

[0004] To achieve the above-mentioned purpose, the utility model adopts a kind of cutting and grinding material supporting mechanisms of shaft parts, which includes a fixed frame, a support rod arranged on the fixed frame, a rotating block rotatably arranged on the support rod, and a pressing strip for pressing shaft parts. The rotating block is provided with a positioning groove matched with the pressing strip. One end of the pressing strip is inserted into the positioning groove, and a plurality of adjusting bolts are arranged on the rotating block corresponding to the positioning groove to press one end of the pressing strip into the positioning groove. The other end of the pressing strip has a limiting part abutting against the outer peripheral wall of the shaft part.

[0005] The cutting and grinding material supporting mechanism has the following beneficial effects: the pressing strip of the cutting and grinding material supporting mechanism is fixed on the rotating block, which can freely rotate on the support rod. The sagging force of the pressing strip presses on the outer peripheral wall of the shaft part, so that the shaft part is positioned on the centerless grinding plate for processing, realizing the radial positioning of the shaft part. The pressing strip is fixed in the positioning groove of the rotating block by adjusting bolts. The operator can replace different specifications of the pressing strip according to different specifications of the shaft part, so that the operation of the cutting and grinding material supporting mechanism is more convenient and has better versatility. Therefore, the cutting and grinding material supporting mechanism of the shaft part has the advantages of simple structure, stable and reliable performance and convenient operation.

[0006] In particular, two limiting blocks are arranged on the support rod corresponding to both sides of the rotating block, and a positioning space for placing the rotating block is formed between the two limiting blocks. The two limiting blocks position the rotating block, so that the position of the rotating block can be adjusted by adjusting the position of the two limiting blocks, which is more convenient to operate.

[0007] Particularly, the rotating block is provided with a through hole through which the supporting rod passes, a bearing is arranged in the through hole and sleeved on the supporting rod, and a gasket is arranged between the bearing and the supporting rod. The bearing can ensure that the rotating block can rotate flexibly, thereby improving the working reliability of the cutting and grinding material supporting mechanism.

[0008] Particularly, the rotating block is provided with a flange covering the bearing on one side. The flange can ensure that the bearing can be positioned in the through hole reliably and that the rotating block can rotate reliably.

[0009] Particularly, the fixing frame is L-shaped, one end of the fixing frame is provided with a plurality of fixing holes, the other end of the fixing frame is provided with a positioning hole matched with the supporting rod, the fixing frame is provided with a slot communicated with the positioning hole, and a bolt is connected to the slot. The fixing frame is provided with a plurality of fixing holes, thereby facilitating the installation of the cutting and grinding material supporting mechanism, the supporting rod is inserted into the positioning hole, thereby facilitating the assembly of the supporting rod and the fixing frame, and the assembly is more convenient.

[0013] As Figs. 1-3As shown, this utility model embodiment is a cutting and grinding support mechanism for shaft parts, including a fixed frame 10, a support rod 11 mounted on the fixed frame 10, a rotating block 12 rotatably mounted on the support rod 11, and a pressure strip 14 for pressing the shaft part 13. The rotating block 12 is provided with a positioning groove 121 that cooperates with the pressure strip 14. One end of the pressure strip 14 is inserted into the positioning groove 121, and the rotating block 12 is provided with multiple adjusting bolts 15 corresponding to the positioning groove 121 to press one end of the pressure strip 14 into the positioning groove 121. The other end of the pressure strip 14 has a limiting part 141 that abuts against the outer peripheral wall of the shaft part 13. The support rod 11 is provided with two limiting blocks 16 on both sides of the rotating block 12, and a positioning space 120 for placing the rotating block 12 is formed between the two limiting blocks 16. The two limiting blocks play a positioning role for the rotating block, so that the position of the rotating block can be adjusted by adjusting the position of the two limiting blocks, making the operation more convenient. The rotating block 12 is provided with a through hole 121 through which the support rod 11 can pass. A bearing 17 is installed in the through hole 121 and fitted onto the support rod 11. A washer 18 is provided between the bearing 17 and the support rod 11. The bearing ensures that the rotating block can rotate flexibly, thereby improving the working reliability of the cutting and grinding material support mechanism.

[0014] like Fig. 2 As shown, a flange 19 covering the bearing 17 is provided on one side of the rotating block 12. The flange ensures that the bearing can be reliably positioned in the through hole, and that the rotating block can rotate reliably. The fixing frame 10 is L-shaped, with multiple fixing holes 101 at one end and a positioning hole 102 that mates with the support rod 11 at the other end. The fixing frame 10 has a slot 103 communicating with the positioning hole 102, and bolts 20 connected to the slot 103 are provided on the fixing frame 10. The fixing frame has multiple fixing holes, which facilitates the installation of the cutting and grinding material support mechanism, and the support rod is inserted into the positioning hole, which facilitates the assembly of the support rod and the fixing frame, making assembly more convenient.

[0015] The pressure bar of this cutting and grinding support mechanism is fixed to a rotating block, which can rotate freely on a support rod. The downward force of the pressure bar presses against the outer peripheral wall of the shaft part, thus positioning the shaft part on the centerless grinding plate for processing, achieving radial positioning of the shaft part. Furthermore, the pressure bar is fixed in the positioning groove of the rotating block by adjusting bolts, allowing operators to change the pressure bar to different specifications for different shaft parts. This makes the operation of the cutting and grinding support mechanism more convenient and versatile. Therefore, this cutting and grinding support mechanism for shaft parts has the advantages of simple structure, stable and reliable performance, and convenient operation.
