[0032] The bottom plate 19 is installed at the lower end of the vertical drilling machine body 6, and support rods 18 are symmetrically arranged on the bottom plate 19. The support rods 18 are made of iron or stainless steel, so that the support rods 18 can bear pressure. The combination of the front hub 4 and the brake drum 5 is placed on the support rods 18. The brake drum 5 and the front hub 4 are assembled together on the assembly platform to form the combination. The bottom of the front hub 4 is provided with bolts 20, which are wheel bolts for installing wheels. The number of the bolts 20 is five, and they are arranged in a circular array along the center of the front hub 4. The top end of the front hub 4 is sleeved with a gear ring 16, which is in interference fit with the outer surface of the top end of the front hub 4. The inner circle of the upper end of the front hub 4 is adapted to the outer surface of the guide block 15. When the gas-liquid supercharged cylinder 9 drives the pressure head rod 10 to move downward, it will drive the gland 14 to move downward. When the gland 14 comes into contact with the gear ring 16, it will push the gear ring 16 to move downward until the lower end surface of the gear ring 16 is in close contact with the gear ring mounting surface of the front hub 4, and the gear ring 16 is completed. The work of pressing is completed. One end of the support rod 18 is fixedly connected with a flow guide rod 1. The end of the flow guide rod 1 away from the support rod 18 extends to the edge of the bottom plate 19 and expands outward to form a trumpet mouth. The ends of the two support rods 18 away from the flow guide rod 1 are provided with positioning rods 2. The outer sides of the two support rods 18 are provided with fixed seats 21. One end of the positioning rod 2 is rotatably connected with one of the fixed seats 21. The other end of the positioning rod 2 is threadedly connected with a plug rod 22. The other fixed seat 21 is provided with a groove matched with the plug rod 22. When the bottom end of the plug rod 22 is inserted into the groove, the positioning rod 2 will be fixed and will play a positioning role. When the plug rod 22 is rotated and driven to move upward and the bottom end of the plug rod 22 is separated from the fixed seat 21, the positioning rod 2 can be easily rotated aside, and the combination after pressing can be easily pushed to the next process along the support rod 18. One side of one of the support rods 18 is provided with a positioning pin 3. When the outer surface of the front hub 4 abuts against the positioning rod 2 and the positioning pin 3 at the same time, the gear ring 16 is located directly below the gland 14.

[0033] The height of the flow guide rod 1 gradually increases from the end away from the support rod 18 to the end close to the support rod 18. A plurality of pre-positioning holes 13 are formed in the bottom plate 19 between the two flow guide rods 1. The pre-positioning holes 13 are tapered counterbores. The pre-positioning holes 13 are arranged in positions and numbers corresponding to the bolts 20. The depth of the pre-positioning holes 13 is 1 mm. The number of the pre-positioning holes 13 is five.

[0034] The bottom plate 19 between the two support rods 18 is provided with a circular groove, which facilitates the suspension of the bottom end of the assembly during the pressing process. Two intermediate guide rods 17 are arranged in the circular groove. The intermediate guide rods 17 are made of copper and have a height lower than that of the support rods 18. When the outer surface of the front hub 4 abuts against the positioning rod 2 and the positioning pin 3, the bolt 20 has a certain gap with the intermediate guide rods 17 and the support rods 18. When the front hub 4 rotates, the bolt 20 first contacts the intermediate guide rods 17. In this way, since the bolt 20 first contacts the intermediate guide rods 17, the intermediate guide rods 17 limit the further rotation of the front hub 4, so that the bolt 20 does not contact the support rods 18 during the pressing process. This is conducive to the arrangement of the support rods 18 close to the center of the assembly. Since the shape of the bottom of the assembly is circular, the support area of the support rods 18 is increased, so that the support rods 18 stably support the assembly and improve the stability during the pressing process. The intermediate guide rods 17 are made of copper, which is soft and will not damage the bolt during the rotation of the assembly. The intermediate guide rods 17 are made of iron or stainless steel and can withstand the pressure during the pressing process of the assembly.

[0035] In some optional embodiments, a sensor mounting plate can be arranged on the outer surface of the lower end of the pressing head rod 10. A displacement sensor can be installed on the sensor mounting plate to control the stroke of the piston rod of the gas-liquid pressure cylinder 9. In this way, it is not necessary for the staff to visually observe whether the lower end surface of the gear ring 16 abuts against the gear ring mounting surface of the front hub 4.

[0036] The working principle of the present application: in specific use, after the current hub 4 and the brake drum 5 are combined on the assembly platform, the workers manually drag the combined assembly along the guide rod 1 to the pressing device platform, when the combined assembly is completely transported on the guide rod 1, the combined assembly is rotated, so that the bolt 20 on the combined assembly corresponds to the pre-positioning hole 13 opened on the bottom plate 19, the bottom end of the bolt 20 is placed in the pre-positioning hole 13, (the combined assembly is pre-positioned); after the combined assembly is pre-positioned, the relative position of the bolt 20 of the combined assembly is kept unchanged, and the combined assembly is dragged along the middle guide rod 17 to the supporting rod 18, until the combined assembly abuts against the positioning rod 2, and one side of the combined assembly abuts against the positioning pin 3, so that the combined assembly is accurately positioned; after the combined assembly is accurately positioned, the workers can place the gear ring 16 on the gear ring mounting shaft neck of the front hub 4, and then start the double-hand button switch with both hands, so that the piston rod of the gas-liquid booster cylinder 9 moves downward, and then drives the pressure head rod 10, the pressure cover 14 and the guide block 15 to move downward together, the guide block 15 enters the inside of the gear ring mounting shaft neck, so that the combined assembly does not slide on the supporting rod 18 during the pressing process, and the guide sleeve 12 can ensure the downward movement precision of the pressure head rod 10 and the pressure cover 14; when the lower end surface of the gear ring 16 abuts against the gear ring mounting surface of the front hub 4, the workers can release the double-hand button switch, so that the piston rod of the gas-liquid booster cylinder 9 moves upward, the gear ring 16 is assembled, the positioning rod 2 is rotated and opened, and the combined assembly can flow into the next process along the supporting rod 18 on the assembly platform.

[0037] In this process, the workers control the double-hand button switch to drive the gas-liquid booster cylinder 9 to press the gear ring 16, which replaces the previous process of knocking the pressure cover with a hammer to realize the gear ring assembly; the pressing device can effectively avoid the safety hazard of workers being injured during operation, and can well ensure the assembly quality of the gear ring 16, and in addition, different pressure covers 14 and guide blocks 15 can be switched to realize the rapid switching of products according to the different shapes and structures of the ABS gear rings.
