Description

Technical Field

[0001] The invention relates to the technical field of coupling equipment, in particular to a coupling position limiting automatic press-fitting machine. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. The two shafts rotate together during the process of transmitting motion and power and do not disengage under normal circumstances. It is sometimes also used as a safety device to prevent the connected parts from being subjected to excessive loads and play an overload protection role. Its main function is to firmly connect the driving shaft and the driven shaft in different mechanisms so that they rotate together and transmit motion and torque. In addition, it can also compensate for the offset (including axial offset, radial offset, angular offset or combined offset) between the two shafts due to inaccurate manufacturing and installation, deformation during operation or thermal expansion, as well as mitigate impact and absorb vibration.

[0003] The coupling needs to be pressed during the processing, but the traditional press-fitting method is not only inefficient but also has low precision, which affects subsequent use. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides an automatic limit-limiting press-fitting machine for a coupling, which solves the problem that the coupling needs to be pressed during the processing process, while the traditional press-fitting method is not only inefficient but also has low precision, thus affecting subsequent use.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a coupling limit automatic press-fitting machine, comprising a processing box, a servo motor and a feeding mechanism, the driving end of the servo motor penetrates the side wall of the processing box, extends to the interior thereof and is fixedly connected to a driving rod, the driving rod one end away from the driving end of the servo motor is fixedly connected to a driving wheel, a feeding roller is arranged inside the processing box, the left and right side walls of the feeding roller are fixedly connected to a mounting rod, the end of the mounting rod away from the feeding roller is rotatably connected to the inner side wall of the processing box, the driving rod is connected to the transmission wheel below it through a transmission belt transmission, the transmission wheel is fixedly sleeved on the outer surface of the mounting rod, a plurality of mounting notches are opened on the outer surface of the feeding roller, the plurality of mounting notches are distributed in a ring array, a plurality of limiting notches are arranged inside the mounting notches, and elastic limiting notches are arranged inside the plurality of limiting notches The top of the transmission plate is fixedly connected with a plurality of transmission tooth plates, and the plurality of transmission tooth plates are distributed in an annular array. The bottom of the transmission plate is fixedly connected with an adjusting cylinder through a telescopic rod, and the bottom of the adjusting cylinder is fixedly connected with a negative pressure plate, and the outer surface of the adjusting cylinder is surrounded by an adjusting notch, and the adjusting notch extends in a vertical direction. The inner side wall of the processing box is fixedly connected with a fixed shaft, and the end of the fixed shaft away from the processing box is slidably engaged with the inner side wall of the adjusting notch, and a driving wheel is arranged above the transmission plate, and the driving wheel is transmission-connected to the driving wheel below it through a transmission belt.

[0006] Preferably, the teeth on the outer surface of the transmission wheel are retractable and adjustable teeth.

[0007] Preferably, the feeding mechanism is located below the feeding roller.

[0008] Preferably, the top center position of the transmission plate is rotatably connected to the inner top of the processing box through a rotating shaft.

[0009] Working principle: When in use, the coupling base to be assembled is transported through the feeding mechanism, and the base is limited by the installation notch opened on the outer surface of the feeding roller and the limiting notch inside the installation notch. When a group of bases to be pressed into place have all entered the installation notch, the servo motor is started. At this time, the teeth on the outside of the transmission wheel are in an extended state. When the feeding roller transports the base inside the installation notch to the top, the teeth on the outside of the transmission wheel are in a retracted state. At this time, the servo motor continues to work, and the teeth on the outer surface of the drive wheel are in an extended state, and the transmission plate belt can be driven through the transmission tooth plate. As the adjusting cylinder makes a rotational motion, since the adjusting slot on the outer surface of the adjusting cylinder extends in the vertical direction and the fixed shaft is slidably engaged in the inside of the adjusting slot, the negative pressure plate will slowly rotate downward to press the components elastically limited inside the elastic positioning piece into the base. Compared with the traditional press-fitting method, this equipment can not only press-fit multiple pieces at one time, but also realize gentle press-fitting to avoid excessive residual stress between components and affect subsequent use. After the press-fitting explanation, it can cooperate with the unloading shaft installed on the outer surface of the feeding mechanism to drive the components to be unloaded, which is convenient and quick.

After the press-fitting explanation, it can cooperate with the unloading shaft installed on the outer surface of the feeding mechanism to drive the components to be unloaded, which is convenient and quick.
