[0021] In order to further understand the structure, features and other purposes of the present invention, the following is a detailed description with reference to the attached preferred embodiments and accompanying drawings. The embodiments described in the drawings are only used to illustrate the technical solutions of the present invention and do not limit the present invention.

[0022] In the first embodiment of the present utility model, as Figure 1 shown, the present utility model provides an automatic protection safety baffle mechanism for the feeding port of a machining equipment, which includes a power mechanism 1, a transmission mechanism 2 and a baffle mechanism 3. The baffle mechanism 3 is erected at one end of the feeding ports of the feeding channels 36 and 36' of the machining equipment. The transmission mechanism 2 is erected on the sides of the feeding channels 36 and 36'. One end of the transmission mechanism 2 is connected to the baffle mechanism 3, and the other end of the transmission mechanism 2 is connected to the power mechanism 1. The power mechanism 1 is erected at the end opposite to the feeding channels 36 and 36'.

[0023] As Figure 1 and Figure 2 shown, the baffle mechanism 3 includes a safety protection baffle 31, and the safety protection baffle 31 is installed directly above the feeding channels 36 and 36'. Rack bars 32 and 32' are respectively installed on both sides of the safety protection baffle 31. Transmission shafts 33 are provided on both sides of the front part of the safety protection baffle 31 and extend to the outside of the feeding channel 36. Gears 34 and 34' are respectively sleeved on both sides of the transmission shaft 33. The gears 34 and 34' are respectively meshed and connected with the rack bars 32 and 32' on both sides of the safety protection baffle 31, so as to drive the gears 34 and 34' to rotate through the transmission shaft 33 and drive the safety protection baffle 31 to lift and lower to control the opening and closing of the feeding port.

[0024] As Figure 1 and Figure 2 shown, the transmission mechanism 2 includes a transmission shaft 33 extending to the outside of the feeding channel 36. A rack and pinion bearing 21 is installed at the extending end of the transmission shaft 33, and a transmission rack 22 is horizontally placed. The rack and pinion bearing 21 is meshed and connected with the transmission rack 22, so as to drive the rack and pinion bearing 21 to drive the transmission shaft 33 to rotate and control the lifting and lowering of the safety protection baffle 31 through the reciprocating motion of the transmission rack 22, providing power transmission and motion direction control for the baffle mechanism 3.

[0025] As Figure 1 and Figure 2 shown, the power mechanism 1 includes a reciprocating feeding oil cylinder 11, and the reciprocating feeding oil cylinder 11 is installed at the end opposite to the feeding channel. The piston push rod of the reciprocating feeding oil cylinder 11 is connected to a workpiece clamp 12. The transmission rack 22 is fixedly connected to the side surface of the workpiece clamp 12. The reciprocating feeding oil cylinder 11 drives the workpiece clamp 12 and the transmission rack 22 to move reciprocally together, providing power for the automatic opening and closing of the baffle mechanism 3. The reciprocating feeding oil cylinder 11 is an original component of the equipment and provides the power required by the device, so there is no need to additionally increase a power device. The reciprocating feeding oil cylinder 11 can push the workpiece clamp 12 to move back and forth on the feeding channel and push the clamped workpiece into the feeding port.

[0026] In this embodiment, after the device is started, an operator places the workpiece on the workpiece fixture 12 of the reciprocating feeding oil cylinder 11. The workpiece fixture 12 automatically clamps the workpiece, and the reciprocating feeding oil cylinder 11 automatically pushes the clamped workpiece into the feeding port. During the forward movement of the reciprocating feeding oil cylinder 11, the driving rack 22 is pushed forward. During the forward movement of the driving rack 22, the rack gear bearing 21 fixed on the transmission shaft 33 is driven to rotate, and the rack gear bearing 21 drives the rotation of the other two sets of gears on the same axis. The rotating gears drive the rack fixed on the safety protection baffle 31, and the safety protection baffle 31 is lifted together. With the completion of the feeding of the processing part, the reciprocating feeding oil cylinder 11 returns and drives the safety protection baffle 31 to descend through the cooperation of the above three sets of gears and racks, and the feeding channel is closed, thus forming a complete cycle.

[0027] In the second embodiment of the present utility model, as Figure 1 shown, gear positioning members 35 and 35' are respectively installed inside the two sets of gears 34 and 34' on the transmission shaft 33 to limit the two sets of gears 34 and 34' by adjusting the positions of the gear positioning members 35 and 35'. By fixing the positions of the gear positioning members on the transmission shaft, the meshing connection between the gears and the racks on both sides of the safety protection baffle is ensured to prevent faults such as the detachment and inclination of the safety protection baffle.

[0028] In the third embodiment of the present utility model, as Figure 1 shown, a positioning plate 38 is provided on the transmission shaft 33 between one side of the feeding channel 36 and the rack gear bearing 21 to limit the transmission shaft 33. By fixing the transmission shaft 33 with the positioning plate 38, the meshing connection between the gears and the racks on both sides of the safety protection baffle is ensured to prevent faults such as the detachment and inclination of the safety protection baffle.

[0029] In the fourth embodiment of the present utility model, as Figure 1 shown, a support frame 37 is installed on the side of the feeding channel 36, and the driving rack 22 is horizontally placed on the support frame 37. The driving rack 22 slides freely on the support frame 37 to improve the stability of the reciprocating movement of the driving rack 22. In this embodiment, the driving rack 22 moves back and forth following the reciprocating feeding oil cylinder 11 and meshes with the gear structure of the rack gear bearing 21 at one end of the transmission shaft 33, and it is required that the horizontal degree of the installation of the driving rack 22 is relatively high. The support frame 37 is in sliding contact with the driving rack, which can minimize the friction generated by the movement, increase the stability of the movement and the service life.

[0030] In the fifth embodiment of the present utility model, as Figure 1As shown, the workpiece fixture 12 reciprocates between the reciprocating feeding oil cylinder 11 and the feeding channel, so that when the reciprocating feeding oil cylinder 11 is in the retracted state, the safety protection baffle 31 descends to completely close the feeding port, and when the workpiece fixture 12 is pushed to the position of the feeding port, the safety protection baffle 31 ascends to open the feeding port. In this embodiment, when the reciprocating feeding oil cylinder 11 is in the retracted state, the safety protection baffle 31 is in the fully closed state, and when the workpiece fixture 12 is pushed to the position of the feeding port, the safety protection baffle 31 is in the fully open state, so as to prevent the workpiece fixture 12 from colliding with the safety protection baffle 31 and causing mechanical failures.

[0031] In the sixth embodiment of the present utility model, as Figure 1 shown, the reciprocating feeding oil cylinder 11 is connected to the first hydraulic pump 13 to provide power for the reciprocating feeding oil cylinder 11 through the first hydraulic pump 13.

[0032] In the seventh embodiment of the present utility model, as Figure 1 shown, a hydraulic cylinder is connected to the top of the workpiece fixture 12, and the hydraulic cylinder is connected to the second hydraulic pump 14 to provide power for the hydraulic cylinder through the second hydraulic pump 14 and drive the workpiece fixture 12 to clamp or release the workpiece.
