Description

Technical Field

[0001] The utility model relates to the field of synchronous wheels, in particular to a synchronous wheel inner hole processing device. Background Art

[0002] A synchronous pulley is a transmission accessory that can mesh with a synchronous belt. It is mainly driven by the synchronous belt and is widely used in new mechanical belt drives in various industries such as automation equipment, machine tools, textiles, printing, food packaging, wires and cables, instruments and meters, petrochemicals, tobacco, and communications.

[0003] When processing the synchronous wheel, according to different common customization requirements, the inner hole of the synchronous wheel needs to be fine-machined according to the diameter of the bearing. When fine-machining the inner hole of the synchronous wheel, the synchronous wheel needs to be fixed on the machining fixture. At this time, the inner hole of the synchronous wheel needs to correspond to the center axis of the machining tool. The existing clamping device has relatively poor positioning accuracy of the center hole when positioning the synchronous wheel, which may result in the inner hole of the synchronous wheel being unusable after fine-machining. Moreover, depending on the size of the synchronous wheel, in order to stably clamp the synchronous wheel during machining, the synchronous teeth of the synchronous wheel may be damaged, which is inconvenient to use.

[0027] The cam 12 is fixed to the workbench 2 and is fixed with two guide rails 6 on both sides, and the guide rails 6 are fixed with two guide rails 6 on both sides.

[0028] A placement table 11 is provided in the center of the groove 10. The cross-section of the customized assembly clamp 7 is an L-shaped structure. The upper end surface of the horizontal section of the customized assembly clamp 7 is flush with the upper end of the placement table 11. The lower end of the synchronous wheel 12 contacts the placement table 11 and the customized assembly clamp 7. The upper end of the customized assembly clamp 7 is provided with an L-shaped upper limit plate 9. The lower end of the horizontal section of the L-shaped upper limit plate 9 contacts the upper end surface of the synchronous wheel 12, and the side of the L-shaped upper limit plate 9 close to the synchronous wheel 12 is an inclined surface. When the synchronous wheel 12 is placed on the placement table 11, the three fixed clamps 5 move toward the position of the synchronous wheel 12 at the same time. After the customized assembly clamp 7 is clamped with the synchronous wheel 12, the upper and lower ends of the synchronous wheel 12 are located in the placement area between the L-shaped upper limit plate 9 and the customized assembly clamp 7 to prevent the synchronous wheel 12 from jumping up, and the side of the customized assembly clamp 7 that contacts the outer peripheral surface of the synchronous wheel 12 is an arc structure.

[0029] In this embodiment, according to the different diameters and thicknesses of the synchronous wheel 12, suitable customized assembly clamps 7 and fixed jaws 5 can be selected for assembly. During assembly, the alignment of the assembly guide plate 6 and the positioning of the assembly screw 8 are coordinated to ensure that the position of the customized assembly clamps 7 is accurate and reliable. Then, when the fixed jaw 5 moves toward the synchronous wheel 12 above the placement table 11, the three customized assembly clamps 7 will assist the placement table 11 to lift the synchronous wheel 12, and then the L-shaped upper limit plate 9 is clamped at the upper end of the synchronous wheel 12. At the same time, in order to avoid the customized assembly clamps 7 from damaging the synchronous teeth of the synchronous wheel 12, the position where the customized assembly clamps 7 contact it is an arc structure of the same size.

[0030] Embodiment 2, on the basis of embodiment 1, a positioning component is provided to assist in positioning the position of the synchronous wheel 12, a chip removal chamber 13 is provided through the center of the processing mounting seat 2, a protective cover 14 is provided at the center of the upper end of the assembly base 1, and the upper end of the protective cover 14 is plugged into the chip removal chamber 13, the positioning component includes a lifting control rod 15 and a conical positioning block 17, and the lifting control rod 15 is placed in the protective cover 14, the upper end of the chip removal chamber 13 is provided through the placement table 11, the diameter of the chip removal chamber 13 is larger than the inner diameter of the center hole of the synchronous wheel 12, the diameter of the chip removal chamber 13 is larger than the diameter of the protective cover 14, a telescopic support rod 16 is vertically provided at the upper end of the lifting control rod 15, the upper end of the telescopic support rod 16 is vertically movable through the top of the protective cover 14, the conical positioning block 17 is vertically provided at the upper end of the telescopic support rod 16 through the protective cover 14, and the upper end diameter of the conical positioning block 17 The conical positioning block 17 is smaller than the inner diameter of the center hole of the synchronous wheel 12, and the lower end diameter of the conical positioning block 17 is larger than the inner diameter of the center hole of the synchronous wheel 12. When the synchronous wheel 12 is located between the L-shaped upper limit plate 9 and the customized assembly clamp 7, the conical positioning block 17 is lifted by the lifting control rod 15. At this time, the conical positioning block 17 is inserted into the inner hole of the synchronous wheel 12 through the conical structure at the upper end, and as the conical positioning block 17 gradually rises, when the synchronous wheel 12 deviates, during the lifting process of the conical positioning block 17, the synchronous wheel 12 cannot be lifted. Therefore, the synchronous wheel 12 can only adjust its posture to adapt to the conical surface of the conical positioning block 17. Therefore, after the conical positioning block 17 assists in positioning the synchronous wheel 12, the three fixed clamps 5 move at the same time through the customized assembly clamp 7 to clamp the synchronous wheel 12, thereby improving the inner hole finishing stability of the synchronous wheel 12.
