Description

Technical Field

[0001] The utility model relates to the field of gear ring processing, in particular to a gear ring component press-fitting die. Background Art

[0002] The ABS ring gear is a key component in the anti-lock braking system. It is usually mounted on the wheel axle or wheel hub to monitor the rotational speed of the wheel. The ABS ring gear is usually made of steel or other high-strength materials and has a uniformly distributed tooth structure. The sensor monitors the rotational speed of the wheel by reading the change in the tooth profile of the ring gear. Ring gear assembly press die is a die used to press the ring gear to other components (such as bearings). The die is designed to ensure that the ring gear and components remain accurately aligned and firmly connected during the press-fit process.

[0003] For example, Chinese patent 201821751881.0 discloses an ABS gear ring press-fitting tool, which places the ABS gear ring on a positioning seat, and then sets the brake disc and wheel hub assembly on an elastic floating mechanism. The clamping mechanism overcomes the elastic force of the elastic floating mechanism and then increases pressure, thereby pressing the ABS gear ring into the brake disc and wheel hub assembly. However, the above tool still has the following shortcomings in specific applications: when the gear ring assembly is press-fitted, the gear ring needs to be press-fitted and connected to the wheel bearing, but the prior art does not heat the gear ring, and the material deformation resistance is large, which is not conducive to the press-fitting effect.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

The top of the guide rod passes through the guide sleeve and extends to the top of the top plate; a connecting plate is arranged at the top of the guide rod, and a buffer is arranged at the bottom of the connecting plate.

[0009] Furthermore, in order to ensure that the gear ring remains accurately aligned during the press-fitting process, the gear ring positioning mechanism includes two first positioning plates arranged inside the installation groove, and the first positioning plate is provided with a first arc surface at one end close to the gear ring, and a first chamfer is provided at the top of the first arc surface.

[0028] With the aid of the above scheme, the utility model can complete the press-fitting of the ring gear assembly, overcome the material deformation resistance during the press-fitting process, improve the press-fitting effect and press-fitting quality, and provide reliable technical support for the production of the ring gear assembly.

[0029] In one embodiment, for the above-mentioned top plate 3, a plurality of guide sleeves 14 are arranged inside the top plate 3, and a guide rod 15 is arranged at the top end of the stamping plate 5, and the top end of the guide rod 15 passes through the guide sleeve 14 and extends to the top of the top plate 3; a connecting plate 16 is arranged at the top end of the guide rod 15, and a buffer 17 is arranged at the bottom end of the connecting plate 16, so as to ensure that the movement trajectory of the stamping plate 5 is stable, and the buffer 17 can reduce the vibration and impact during the pressing process, thereby protecting the mold and the workpiece.

[0030] In one embodiment, for the above-mentioned ring gear positioning mechanism 9, the ring gear positioning mechanism 9 includes two first positioning plates 901 arranged inside the mounting groove 8, the first positioning plate 901 is provided with a first arc surface 902 at one end close to the ring gear 10, and the top of the first arc surface 902 is provided with a first chamfer; the bearing positioning mechanism 11 includes two L-shaped mounting frames 1101 arranged at the top of the die 7, and the top of the L-shaped mounting frame 1101 is provided with a second positioning plate 1102; the second positioning plate 1102 is provided with a second arc surface 1103 at one end close to the bearing 12, and the top of the second arc surface 1103 is provided with a second chamfer, so as to ensure that the ring gear 10 and the bearing 12 are accurately aligned during the press-fitting process, prevent the components from shifting or misaligning during the press-fitting process, and improve the accuracy and stability of the press-fitting.

[0031] In addition, the first positioning plate 901 is connected to the die 7 via screws and positioning pins, and the bottom of the L-shaped mounting frame 1101 is connected to the die 7 via screws and positioning pins.

[0032] The working principles of the gear ring positioning mechanism 9 and the bearing positioning mechanism 11 are as follows: the first arcuate surface 902 matches the shape of the gear ring 10, and the first chamfer helps the gear ring 10 to smoothly enter the positioning position; the second arcuate surface 1103 of the second positioning plate 1102 matches the shape of the bearing 12, and the second chamfer helps the bearing 12 to smoothly enter the positioning position, thereby ensuring the accurate positioning of the bearing 12 during the press-fitting process.

[0033] In one embodiment, for the above-mentioned heating component 13, the heating component 13 includes a heating plate 1301 arranged at the bottom end of the ring gear 10 and located inside the die 7. The heating plate 1301 is connected to an external power source through an electric wire and is made of a high-resistance material, such as nickel-chromium alloy or constantan alloy.

[0034] The working principle of the heating assembly 13 is as follows: after the heating plate 1301 is powered on, heat is generated and transferred to the ring gear 10. By heating, the material of the ring gear 10 becomes softer, reducing deformation resistance.

[0035] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0036] In actual application, the ring gear 10 is placed in the ring gear positioning mechanism 9 inside the die 7. The bearing 12 is placed in the bearing positioning mechanism 11 at the top of the die 7. At this time, the bottom end of the bearing 12 is aligned with the hole in the middle of the ring gear 10. Start the heating component 13 to heat the ring gear 10. Start the booster cylinder 4, which applies pressure downward through its output shaft to drive the punch plate 5 and the punch head 6 to move downward. The punch head 6 applies pressure to press the bearing 12 onto the heated ring gear 10. The setting of the connecting plate 16 and the buffer 17 reduces the vibration and impact during the press-fitting process and protects the mold and the workpiece. After the press-fitting is completed, check the connection quality of the ring gear and the bearing to ensure that there is no looseness or misalignment.

If the booster cylinder 4 is a pneumatic booster cylinder, ensure that it is correctly connected to the air source. If the booster cylinder 4 is a hydraulic booster cylinder, ensure that it is correctly connected to the hydraulic oil source.

[0038] In summary, the utility model can complete the press-fitting of the gear ring assembly, overcome the material deformation resistance during the press-fitting process, improve the press-fitting effect and press-fitting quality, and provide reliable technical support for the production of the gear ring assembly. By setting the guide rod 15 and the guide sleeve 14, the movement trajectory of the stamping plate 5 is ensured to be stable, and the buffer 17 can reduce the vibration and impact during the press-fitting process to protect the mold and the workpiece. By setting the gear ring positioning mechanism 9 and the bearing positioning mechanism 11, it is possible to ensure that the gear ring 10 and the bearing 12 remain accurately aligned during the press-fitting process, prevent the components from shifting or misaligning during the press-fitting process, and improve the accuracy and stability of the press-fitting. By setting the heating component 13, the gear ring 10 is heated by the heating plate 1301, which can effectively reduce the deformation resistance of the gear ring 10 material and make the press-fitting process smoother.
