Detailed ways:

For better understanding of the utility model, below in conjunction with accompanying drawing and embodiment it is described in further detail:

Embodiment: As shown in Figure 1, a tailstock of a stepless speed regulation automatic advance and retreat lathe includes a Morse seat 1, a travel switch fixing frame 2, a travel switch 3, a tailstock 4, an adjustable travel switch frame 5, and a tailstock screw Revolving shaft 6, coupling 7, reducer output shaft 8, docking plate 9, electrical control switch 10, reducer 11, motor shaft 12, motor 13, frequency converter 14, distribution box 15, which is provided with tailstock direct connection structure, including tailstock 4 connected to docking plate 9, reducer 11 directly connected to motor 13, tailstock screw shaft 6 connected to coupling 7, reducer output shaft 8, through reducer 11, motor shaft 12 and reducer The input shafts of the machine are connected, and the rotation of the motor 13 drives the reducer 11 and the output shaft 8 of the reducer to rotate, and is connected to the tailstock screw shaft 6 through the coupling 7 to rotate and push the Morse seat 1 to advance and retreat to achieve automatic advance and retreat; it is equipped with The frequency conversion control structure of the tailstock electric appliance includes an electric appliance control switch 10. The electric appliance control switch 10 is provided with slow forward, slow backward, fast forward, fast reverse function keys and an analog speed regulating switch that can select slow forward. Or retreat speed, and establish emergency stop switch; Adjustable travel switch frame 5 is provided with travel switch 3 with limit protection function.

Morse seat 1 is mainly used to install cutting tools such as drill bits, boring tools, reamers, and tapping cones; travel switch holder 2 is used to install electromagnetic travel switch magnets; travel switch 3 can adjust the size of advance and retreat according to the depth of the workpiece To the protective effect; the tailstock 4 is connected to the docking plate 9; the reducer 11 is directly connected to the motor 13 to achieve the integration of the tailstock connection; the adjustable travel switch frame 5 is equipped with the travel switch 3, which is used to adjust the feed size of the tailstock for safety control Function: the tailstock screw shaft 6 is connected with the coupling 7 and the output shaft 8 of the reducer, and the reducer 11 and the motor shaft 12 are connected with the input shaft of the reducer, and the motor 13 rotates to drive the reducer 11 and the output shaft 8 of the reducer Rotate, connect the tailstock screw shaft 6 through the coupling 7 to rotate and push the Morse seat 1 to advance and retreat to achieve the automatic advance and retreat function. The motor control switch 10 utilizes the frequency converter 14 for stepless speed regulation. By setting the segment speed function of the frequency converter, four frequency segments of slow forward, fast forward, slow rewind and fast rewind are set, so that every time a function selection button is pressed , The motor works at a frequency, that is, at a speed to achieve a function. In order to adjust the feed speed conveniently according to different working conditions under the slow-moving working state, an analog speed regulating knob is specially set on the motor control switch 10 panel to adjust the motor speed in time. In order to prevent the tailstock from advancing or retreating beyond the limit and damaging the machine tool, a travel switch 3 is specially added to the adjustable travel switch frame 5. When the tailstock advances or retreats to the position of the travel switch, it will automatically stop and lock itself so that it cannot continue to move forward or backward. The control part of the motor control switch 10 is also provided with an emergency stop function, and the emergency stop switch is pressed in an emergency state, and the motor stops rotating to achieve safety purposes. The display panel of the frequency converter 14 shows the operating frequency and status. A frequency converter, a switch, and an intermediate relay are arranged in the distribution box 15 .
