technical field

The utility model relates to an automatic acquisition device for the running state of a press, in particular to a signal transmission device for the rotational speed of an eccentric gear type closed double-point press.

Background technique

For the closed two-point press with eccentric gear, since the gear shaft supporting the eccentric gear does not rotate with the eccentric gear, the press signal cannot be output synchronously through the gear shaft. Therefore, for a press with automation requirements, it is necessary to configure a signal acquisition device that can obtain the working status of the press online.

Detailed ways

The utility model is shown in Figures 1 and 2, the press includes an eccentric gear and a gear shaft meshed according to a transmission ratio of X: 1, wherein X is 2-5, and the signal transmission device includes a gear shaft fixedly connected to the gear shaft The shaft 1 on the end face, the small sprocket 2 fixedly connected to the other end of the shaft 1, the large sprocket 3 connected to the small sprocket 2 through a transmission chain, the speed receiving conversion device and the mounting seat 4; the speed receiving conversion The device is fixedly connected to the mounting base 4, and the rotational speed receiving conversion device includes a transmission shaft 10, a rotary encoder 8 and a housing 11, and the transmission shaft 10 is movably connected in the housing 11, and the rotary encoder 8 It is connected with one end of the sending shaft 10 ; the large sprocket 3 is connected with the other end of the sending shaft 10 .

The transmission ratio of the small sprocket 2 and the large sprocket 3 is 1:X.

The transmission shaft 10 is connected to the rotary encoder 8 through an elastic coupling 7 .

During specific manufacture: shaft 1 is installed on the end face of the gear shaft (dual dot dash line shows in Fig. 1) meshed with the eccentric gear, and small sprocket 2 is connected with shaft 1 by key. The mounting base 4 is fixed on the back of the fuselage, the bracket 5 is installed on the mounting base 4, and the left and right positions can be adjusted by set screws. Housing 11 is installed on the support 5, built-in bearing, and separates with spacer 6, and sending shaft 10 is installed in the cover 11, and large chain wheel 3 is connected with sending shaft 10 by key. The gland 12 is installed on the end face of the sleeve 11 . The small sprocket 2 and the large sprocket 3 are driven by a chain. The rotary encoder 8 is fixed on the end cover 9, and the end cover 9 is connected with the sleeve 11. The rotary encoder 8 is connected with the transmission shaft 10 through the elastic coupling 7 .

The working principle of the utility model is: when the machine tool is working, the gear shaft meshed with the eccentric gear drives the shaft 1 connected to it to rotate, and the small sprocket 2 fixed on the shaft 1 drives the large sprocket through the roller chain (transmission chain) 3 rotate, and then drive the sending shaft 10 to rotate together. Suppose the transmission ratio between the eccentric gear and the gear shaft is 4:1, that is, the speed of the gear shaft is 4 times the speed of the eccentric gear, so the transmission ratio between the small sprocket 2 and the large sprocket 3 must be 1:4, that is, the small sprocket The rotational speed of 2 must be 4 times of the rotational speed of the large sprocket 3, so as to ensure that the rotational speed of the transmission shaft is synchronized with the eccentric gear; and then ensure that the rotational speed of the rotary encoder 8 connected to the transmission shaft 10 through the elastic coupling 7 is synchronized with the eccentric gear , thus ensuring the accurate output of various signals between the press through the rotary encoder 8 and the host PLC.
