Embodiment Construction
[0022] The present invention will be further described in detail below with reference to the drawings and specific embodiments.
[0023] The present invention uses a milling machine instead of a car to process both ends of a slender shaft at the same time. The device includes a body 1 and a camshaft 3 that runs through the body 1 and is driven by a first motor 2. The camshaft 3 is provided with two cams and A sprocket is a first cam 4, a second cam 5, and a first sprocket 40. The first cam 4 drives the first prying rod 7 to pry the first push rod 8 to move, and the first push rod 8 is sleeved in the first sleeve 9 to push the slender shaft blank falling into the first sleeve; the second cam 5 drives the second pry bar 10 to pry the second push bar 11 to move, so The second push rod 11 is connected to the traveling tool post 12 to drive the traveling tool post to move when the second push rod is pushed. The traveling tool post 12 is provided with a cutter head 14 driven to rotate ...

The invention relates to a device and method for machining the two ends of a long and thin shaft simultaneously with turning replaced by milling. The device for machining the two ends of the long and thin shaft simultaneously with turning replaced by milling is characterized by comprising a machine body and a cam shaft which is arranged on the machine body in a penetrating manner and driven by a first motor, and the cam shaft is provided with a first cam, a second cam and a first chain wheel; the first cam drives a first prying rod to pry a first push rod, the first push rod is made to move, and the first push rod is sleeved with a first sleeve so as to push a long and thin shaft blank fallen into the first sleeve; and the second cam drives a second prying rod to pry a second push rod, the second push rod is made to move, the second push rod is connected with an advancing cutter rest so as to drive the advancing cutter rest to move when the second push rod is pushed, and a cutter head which is driven by a second motor to rotate is arranged on the advancing cutter rest. According to the device for machining the two ends of the long and thin shaft simultaneously with turning replaced by milling, because one single first motor is used for feeding and clamping workpieces, driving the workpieces to rotate and achieving cutter feeding through the three cam mechanisms, the mechanical structure is simple and compact, and the manufacturing cost is low. Besides, because repeated locating and clamping of the same long and thin shaft are not needed, the production efficiency is significantly improved, and the coaxiality of the two ends of the machined long and thin shaft is guaranteed beneficially.
Description
Technical field: [0001] The invention relates to a device and method for simultaneously processing both ends of a slender shaft by using a milling instead of a car. Background technique: [0002] In the processing and production of mechanical parts, it is often encountered that both ends of the slender rod must be processed and the same size requirements (such as simple needle roller bearing cage column, toy car wheel axle, etc.). The number of such parts is large, and the accuracy requirements are not very high. At present, such parts are mostly processed by instrument lathes, small CNC lathes and other equipment. After turning one end, the other end of the turning must be turned around. The processing steps are troublesome, the efficiency is low, and the coaxiality of the two ends is not easy to guarantee. Summary of the invention: [0003] The purpose of the present invention is to provide a device and method for simultaneously processing both ends of a slender shaft by using ...
