[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 4 As shown, a hydraulic mechanical safety device comprises a machine body 1 and a brake 2 installed in the machine body 1, the brake 2 is a hydraulic brake, a processing plate 3 is installed at the output end of the brake 2, an infrared sensor 6 is installed at the bottom of the processing plate 3, and a controller is arranged in the machine body 1. When the infrared sensor 6 detects that a human body part appears under the processing plate 3, the information can be fed back to the controller, and the controller interrupts the movement of the brake 2, so as to prevent the staff from being crushed by the processing plate 3;

[0026] A processing table 4 is installed on the front side of the machine body 1. A slide groove 13 is opened inside the processing table 4. A push rod 12 is slidably installed inside the slide groove 13. The push rod 12 is set as a U-shaped rod. The upper end of the push rod 12 is fixedly connected with a feeding plate 11 for pushing the workpiece. The workpiece is placed on the processing table 4. Pushing the push rod 12 can drive the feeding plate 11 to move. The feeding plate 11 can push the workpiece to the bottom of the processing plate 3. This arrangement can prevent the staff from directly sending the workpiece to the processing position by hand. When loading, the staff does not need to extend their hands under the processing plate 3, thereby further preventing the staff from being crushed and enhancing the safety of the equipment.

[0027] In order to facilitate the control of the processing position of the workpiece, the following settings are made: a positioning plate 5 is slidably installed on the top of the processing table 4, and an adjusting mechanism 7 for adjusting the position of the positioning plate 5 is arranged on the positioning plate 5. A driving part 8 for driving the adjusting mechanism 7 is arranged on one side of the body 1. The driving part 8 can drive the adjusting mechanism 7 to adjust the position of the positioning plate 5. By adjusting the position of the positioning plate 5, the final stop position of the workpiece on the processing table 4 can be controlled. When pushing the workpiece, it is only necessary to push the workpiece until it abuts against the positioning plate 5. The staff can adjust the position of the positioning plate 5 according to the processing requirements. In addition, when the equipment is processing some light workpieces that are prone to displacement, the staff can also push the push rod 12 to drive the feeding plate 11 to press the workpiece during the processing. The workpiece is clamped by the feeding plate 11 and the positioning plate 5, which can fix the workpiece and prevent the workpiece from shifting during the processing.

[0028] Furthermore, limit plates 9 are movably installed on both sides of the top of the processing table 4, and a plurality of installation grooves 10 for the limit plates 9 to be inserted are provided on the top of the processing table 4. The workpiece can be limited by the limit plates 9 to ensure that the workpiece can move vertically when the feeding plate 11 pushes the workpiece to prevent the workpiece from shifting. By setting a plurality of installation grooves 10, the distance between the two limit plates 9 can be changed, which is convenient for use with workpieces of different sizes.

[0029] Furthermore, a spring 14 is fixedly connected to the lower end of the push rod 12, and one end of the spring 14 away from the push rod 12 is fixedly connected to the inner wall of the slide groove 13. When the push rod 12 is pushed, the push rod 12 can squeeze the slide groove 13, and the slide groove 13 is deformed. After pushing the workpiece to the specified position, the push rod 12 can be reset by the elastic force of the slide groove 13, which is convenient for the next pushing work.

[0030] Specifically, the adjustment mechanism 7 includes a rotating shaft 71, which is rotatably installed in the body 1, and both ends of the rotating shaft 71 are fixedly connected with a gear 75, a connecting rod 73 is rotatably installed on one side of the gear 75, and a fixing rod 74 is rotatably installed on the lower end of the connecting rod 73. The end of the fixing rod 74 is fixedly installed on the side of the positioning plate 5. The rotation of the rotating shaft 71 drives the gear 75 to rotate, and the rotation of the gear 75 pulls the connecting rod 73. The connecting rod 73 can drive the positioning plate 5 to slide forward or backward through the fixing rod 74, so as to adjust the position of the positioning plate 5.

[0031] More specifically, the driving unit 8 includes a motor 81, and a hanger 84 for fixing the power supply motor 81 is installed on the side of the body 1. The output end of the motor 81 is fixedly connected to a gear 2 82, and the gear 2 82 is meshed with the gear 1 75. The driving motor 81 drives the gear 2 82 to rotate, and the rotation of the gear 2 82 can drive the gear 1 75 to rotate.

[0032] Reference Figure 3As shown, the front end of the processing table 4 is installed with a matching belt and belt buckle, and the belt and belt buckle are respectively arranged on both sides of the slide groove 13. When the equipment is not in use, the push rod 12 can be pushed into the slide groove 13 and fixed by the belt and belt buckle, which can save the space occupied by the equipment.

[0033] Working principle: When in use, place the workpiece at the front end of the processing table 4, push the push rod 12 to drive the feeding plate 11 to push the workpiece to abut against the positioning plate 5. At this time, the workpiece is under the processing plate 3. If you need to adjust the processing position of the workpiece, drive the adjustment mechanism 7 through the drive unit 8 to drive the positioning plate 5 to slide. The positioning plate 5 slides forward to push the workpiece forward, and the positioning plate 5 slides backward to continue to push the push rod 12 to push the workpiece backward. After the adjustment is completed, the brake 2 can be driven to process the workpiece. With this arrangement, the staff does not need to extend their hands under the processing plate 3 when loading materials, which can avoid the staff from being crushed. During the processing of the equipment, the infrared sensor 6 can be used to monitor the bottom of the processing plate 3. When it is detected that a human body part appears under the processing plate 3, the movement of the brake 2 can be interrupted in time to improve the safety of the equipment.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
