Problems solved by technology

[0003] Existing bushings with large internal diameters are reamed by manually using a cutting knife to cut off the redundant part of the inner frame. However, during the process of expanding the inner diameter of the inner frame, since the inner frame is generally made of aluminum, the cutting Some debris may be generated, these debris splash around and are not easy to collect, resulting in the inability to recycle the debris, resulting in waste of resources. The influence of thermal stress itself makes cutting more difficult and cutting efficiency lower. Therefore, how to reasonably solve this problem is what we need to consider

Abstract

The invention discloses a dual-station reaming tool for an automobile chassis bushing, which includes a base, two support columns are arranged symmetrically above the base, and a top plate is fixedly connected to the top of the two support columns. The lower end of the top plate is rotatably connected with two rotating rods, the lower ends of the two rotating rods are fixedly connected with electric telescopic rods, the telescopic ends of the two electric telescopic rods are fixedly connected with mounting plates, and the lower ends of the two mounting plates are An annular blade is fixedly connected; a moving cavity is arranged in the top plate, and the upper end of the rotating rod on the left side extends into the moving cavity. When the device is reaming, it will generate hot airflow to heat up the inner frame and reduce its thermal stress, so that the cutting can be facilitated and the efficiency of reaming the inner diameter of the inner frame can be improved. Cooling treatment, so that it is convenient for subsequent workers to take it out, and the debris can be automatically collected after the reaming is completed, which is convenient for recycling.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a dual-station reaming tool for an automobile chassis bushing. Background technique [0002] With the development of the automobile field, in order to reduce the overall weight of the car, a lightweight rubber shock absorbing bush will be used. The existing rubber shock absorbing bush reduces the outer diameter of the product through certain technical means in the manufacturing process. The size eliminates the rubber internal stress between the outer frame and the middle frame, and increases the inner diameter of the inner frame of the bushing to expand the hole to eliminate the rubber internal stress between the inner frame and the middle frame and improve the durability of the product. However, the existing bushing The skeleton inner diameter reaming device still has the following problems: [0003] Existing bushings with large internal diameters are reamed by manually usi...
