Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic press auxiliary equipment, in particular to a hydraulic press locking mechanism. Background Art

[0002] A conventional hydraulic press includes a guide column, a top seat, a hydraulic cylinder and a slide. The top seat is fixed at the upper end of the guide column, and the hydraulic cylinder acts on the slide through the top seat, thereby ensuring that the slide slides up and down along the guide column, thereby achieving the extrusion, forming and other processing requirements of the workpiece. When the object to be compressed is placed at the bottom of the slide, the slide will be raised first by the hydraulic cylinder. During the process of placing the object, once the hydraulic cylinder fails, the slide is very likely to slide along the guide column, causing damage to the object or even personnel. How to avoid this situation has become a problem that people urgently need to solve, so it is necessary to develop a hydraulic press locking mechanism. Utility Model Content

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] See also Figure 1-Figure 4 , shows a schematic diagram of the structure of a hydraulic press locking mechanism implementation method of the utility model, please refer to Figure 1-Figure 4 , a hydraulic press locking mechanism is introduced in detail.

[0025] A locking mechanism for a hydraulic press includes a hydraulic press 100, wherein the hydraulic press 100 includes a placement base 110, wherein vertical columnar guide columns 120 are arranged around the top of the placement base 110, wherein a top seat 130 is commonly arranged on the top of the four guide columns 120, and a slide seat 140 is commonly slidably arranged on the rod body, wherein a vertical hydraulic cylinder 150 is arranged at the top center of the top seat 130, and an output end of the hydraulic cylinder 150 slides through the top of the top seat 130 and is connected to the top center of the slide seat 140;

[0026] A mounting frame 200 is disposed on the top of the slide 140. A through hole 210 is opened in the center of the mounting frame 200 for the output end of the hydraulic cylinder 150 to pass through. The through hole 210 prevents the output shaft of the hydraulic cylinder 150 from directly contacting the top of the mounting frame 200, thereby preventing the hydraulic cylinder 150 from causing pressure damage to the mounting frame 200 when working.

[0027] The inner cavity of the mounting frame 200 is provided with transverse threaded rods 220 which are symmetrically rotated left and right. The rod bodies of the two threaded rods 220 are respectively threaded with connecting plates 230 which are penetrated. The threads of the two threaded rods 220 run in opposite directions. The two ends of the two connecting plates 230 which are far away from each other are provided with locking pins 240 protruding therefrom. There are four locking pins 240. The side walls of the four guide columns 120 are respectively provided with plug holes 250 for inserting the other ends of the four locking pins 240. It should be noted that the height of the plug holes 250 is the horizontal position corresponding to the locking pin 240 when the output shaft of the hydraulic cylinder 150 is completely reset, that is, when it is not extended, which is the opening position of the plug holes 250.

[0028] A driving assembly for driving the two threaded rods 220 to rotate synchronously is disposed inside the mounting frame 200 .

[0029] Furthermore, a guide rod 260 is provided on the side walls of the two connecting plates 230 for sliding together. The guide rod 260 and the threaded rod 220 are provided in parallel with each other. Both ends of the guide rod 260 are provided on the inner wall of the mounting frame 200. The guide rod 260 serves as a limiting guide for the connecting plates 230. When the threaded rod 220 rotates, the connecting plates 230 will not rotate therewith, but move along the rod body of the guide rod 260.

[0030] The two ends of the guide rod 340 are arranged on the inner wall of the mounting frame 200, and the two ends of the guide rod 340 are arranged on the inner wall of the mounting frame 200. The guide rod 340 has a limiting value and a limiting value.

[0031] Furthermore, one end of the threaded column 300 is rotatably extended to the outer wall of the mounting bracket 200 , and a hand crank 350 is provided at the end of the threaded column 300 , so that the threaded column 300 can be conveniently driven to rotate by the external hand crank 350 .

[0032] During specific use, when it is necessary to lock the position of the slide 140, the output shaft of the hydraulic cylinder 150 is completely reset. At this time, the four locking pins 240 are aligned with the positions of the sockets 250 one by one, and the threaded column 300 is driven to rotate by the hand crank 350, so that the movable plate 310 pushes the rack 320 to move, thereby driving the gear 330 and the threaded rod 220 to rotate. At this time, the distance between the two connecting plates 230 becomes larger, driving the four locking pins 240 to be inserted into the holes of the four sockets 250 respectively, thereby assisting in fixing the slide 140, and to a certain extent reducing the risk of the slide 140 falling when the object to be compressed is placed on the base 110.

[0033] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
