Problems solved by technology

[0002] After the hub hole of the locomotive integral wheel is processed on the vertical lathe, there are tool marks distributed in the hub hole, and the surface roughness of the hub hole cannot meet the assembly requirements. Due to the interference fit between the integral wheel and the axle, during assembly, It will cause damage to the installation end face of the axle, affect the service life of the axle, and even lead to the scrapping of the assembled product
[0003] At present, the knife marks in the hub hole are processed by manual sandpaper grinding, but this method is inefficient, the quality of grinding is difficult to be guaranteed, and there is a great safety risk
By using a grinding machine to process the hub hole, additional equipment is required, which increases the production cost, and adds a part transfer, clamping and positioning process, which reduces the processing efficiency

Embodiment Construction

[0021] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the integral wheel hub hole rolling tool provided by the present invention includes a cutter bar 1, a cutter body 2, a rolling wheel 3, and a pressing block 4; the cutter bar 1 is fixedly connected to the cutter body 2, and the cutter bar 1 can be It is connected with the cutter body 2 by welding, and the cutter bar 1 and the cutter body 2 can also be an integral part. The shape of the cutter bar 1 is not limited. The cutter bar 1 is installed horizontally on the main shaft of the vertical lathe, so that the rolling tool can make a circular motion around the main shaft on the plane, that is, to polish the roughness of the surface of the hub hole of the integral wheel. Such as figure 2 As shown, the rolling wheel 3 includes a roller 6 and a roller 7, the roller 6 and the roller 7 are integral parts, the rolli...

Abstract

The invention relates to the technical field of rolling cutters, in particular to a rolling cutter for machining a hub hole of a whole wheel. The rolling cutter for the hub hole of the whole wheel comprises a cutter rod, a cutter body, a rolling wheel and a pressing block. The cutter rod is fixedly connected with the cutter body. A cavity matched with the rolling wheel is formed in the cutter body. The rolling wheel is located in the cavity. The rolling wheel comprises a rolling wheel body and a rolling shaft. The pressing block is located at the upper end of the cavity. The pressing block and the cutter body are detachably connected. A groove matched with the rolling shaft is formed in the bottom of the pressing block. A threaded hole communicating with the groove is formed in the top of the pressing block. An adjusting bolt is located in the threaded hole. After the hub hole is machined through a vertical lathe, the rolling cutter is replaced on the vertical lathe, the surface of the hub hole is rolled, cutter marks are eliminated, the surface roughness of the hub hole is improved, no extra grinding device is needed, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of rolling tools, in particular to a rolling tool used for machining the hub hole of an integral wheel. Background technique [0002] After the hub hole of the locomotive integral wheel is processed on the vertical lathe, there are tool marks distributed in the hub hole, and the surface roughness of the hub hole cannot meet the assembly requirements. Due to the interference fit between the integral wheel and the axle, during assembly, It will cause damage to the installation end face of the axle, affect the service life of the axle, and even cause the product after assembly to be scrapped. [0003] At present, the knife marks in the hub hole are processed manually by grinding with sandpaper, but this method is inefficient, the quality of grinding is difficult to be guaranteed, and there is a great safety risk. By using a grinding machine to process the hub hole, additional equipment is required, which incre...
