Description

Technical Field

[0001] The utility model relates to a supporting mechanism for box body processing, in particular to a hydraulic auxiliary supporting mechanism for box body processing. Background Art

[0002] When hydraulically pressing the corners of a box body, when the box body approaches the hydraulic pressing mechanism, the box body is likely to interfere with the oil cylinder of the hydraulic pressing mechanism, so that a standard oil cylinder cannot be used for hydraulic processing of the corners of the box body. Therefore, it is necessary to improve the structure of the hydraulic pressing mechanism. After the size of the upper end of the jacking oil cylinder on the hydraulic pressing mechanism is made smaller and longer, although there will be no interference with the box body, the slender structure of the upper end of the jacking oil cylinder will become unstable. Especially when the slender upper end of the jacking oil cylinder is press-fitted, the upper end of the jacking oil cylinder is easily inclined and offset under a large extrusion force. Therefore, how to prevent the upper end of the jacking oil cylinder from tilting and offsetting when hydraulically pressing the corners of the box body, so as to prevent damage to the jacking oil cylinder, still requires further research. Summary of the Utility Model

Specific embodiments

[0016] The following further describes the present utility model in conjunction with embodiments and the accompanying drawings: Embodiment 1

[0017] As Figure 1 and Figure 2 shown, the hydraulic auxiliary support mechanism for box body processing includes a base 1, an upper jacking mechanism, a lower support seat, and an upper support seat. The upper jacking mechanism includes an upper jacking oil cylinder 41, a middle plate 52, and a jacking rod 51. The upper jacking oil cylinder 41 is provided with an upper jacking piston rod 42. A through mounting hole is opened on the middle plate 52, and an internal thread is provided in the mounting hole. External threads are provided at the upper end of the upper jacking piston rod 42 and the lower end of the jacking rod 51, and the upper end of the upper jacking piston rod 42 and the lower end of the jacking rod 51 are screwed into the mounting hole of the middle plate 52, connecting the upper jacking piston rod 42 and the jacking rod 51 together through the middle plate 52.

[0018] A downwardly concave mounting hole is opened at the top of the base 1, and the lower end of the upper jacking oil cylinder 41 is embedded in the concave mounting hole. A through mounting hole is opened on the upper jacking oil cylinder 41, and a threaded hole corresponding to the through mounting hole is opened on the base 1. A bolt passes through the mounting hole of the upper jacking oil cylinder 41 and is screwed into the threaded hole of the base 1 to fixedly connect the upper jacking oil cylinder 41 and the base 1.

[0019] A pressing oil cylinder 21 is further provided on one side of the upper jacking oil cylinder 41. A through mounting hole is opened at the corner of the upper end of the pressing oil cylinder 21, and a threaded hole corresponding to the mounting hole is opened on the base 1. A bolt passes through the mounting hole of the pressing oil cylinder 21 and is screwed into the threaded hole of the base 1 to fixedly connect the pressing oil cylinder 21 and the base 1. The pressing oil cylinder 21 is provided with a hydraulic piston rod 22, and the upper end of the hydraulic piston rod 22 is connected to a rotating pressing arm. The rotating pressing arm includes a main body 31 and an arm rod 32. One side of the upper end of the rotating pressing arm extends laterally to form an arm rod 32, so that the main body 31 and the arm rod 32 are seamlessly connected into a whole. A mounting hole is opened at the lower end of the main body 31 of the rotating pressing arm, an internal thread is provided in the mounting hole, an external thread is provided at the upper end of the hydraulic piston rod 22, and the hydraulic piston rod 22 is in threaded fit connection with the rotating pressing arm. Starting the pressing oil cylinder 21 can make the hydraulic piston rod 22 extend and retract, thereby driving the rotating pressing arm to move vertically downward or vertically upward.

[0020] As Figures 1 to 3As shown in the figure, the lower support base includes a chassis 61 and a lower seat body 63. The lower seat body 63 is arranged above the chassis 61, and the lower seat body 63 and the chassis 61 are integrally formed as a whole. Through mounting holes are formed in the chassis 61, and threaded holes corresponding to the through mounting holes are formed in the base 1. Bolts pass through the mounting holes of the chassis 61 and are tightened in the threaded holes of the base 1, so that the lower support base is fixedly connected to the base 1. Since the distance between the upper jacking oil cylinder 41 and the pressing oil cylinder 21 is relatively small, in order to prevent the chassis 61 of the lower support base from interfering with the pressing oil cylinder 21. In this embodiment, the chassis 61 on the side close to the pressing oil cylinder 21 is vertically cut, so that a flat disk cutting surface 62 is formed on the chassis 61.

[0021] The upper support base includes a guide rod 71, a limit cone 72, an upper seat body 73 and a seat sleeve 74. The top of the limit cone 72 is seamlessly connected to the bottom of the guide rod 71, the bottom of the limit cone 72 is seamlessly connected to the top of the upper seat body 73, the bottom of the upper seat body 73 is seamlessly connected to the top of the seat sleeve 74. The seat sleeve 74 is circular tubular, and the guide rod 71, the limit cone 72, the upper seat body 73 and the seat sleeve 74 are integrally formed as a whole. The upper end of the lower seat body 63 is sleeved on the seat sleeve 74. Through mounting holes are formed in the circumferential direction of the upper seat body 73, and threaded holes corresponding to the mounting holes are formed in the top of the lower seat body 63. Bolts pass through the mounting holes and the threaded holes, so that the upper seat body 73 and the lower seat body 63 are fixedly connected together.

[0022] Both the lower support base and the upper support base are provided with through cavities. The upper jacking mechanism is arranged in the cavities of the lower support base and the upper support base. The guide rod 71 of the upper support base is sleeved on the jacking rod 51 of the upper jacking mechanism. Starting the upper jacking oil cylinder 41 can make the hydraulic piston rod 22 drive the jacking rod 51 to move vertically upward or downward, and the guide rod 71 of the upper support base can prevent the jacking rod 51 from tilting and offsetting when pressing the box body. Therefore, the guide rod 71 of the upper support base can support the jacking rod 51 in the horizontal direction and play a guiding role in the vertical direction.

[0023] In order to prevent the box body from interfering with the upper seat body 73, one side of the guide rod 71 and the limit cone 72 of the upper support base is vertically cut, and a vertical cutting surface 75 is formed on the guide rod 71 and the limit cone 72. And the limit cone 72 is also horizontally cut, and a horizontal cutting surface 76 is formed on the limit cone 72. The vertical cutting surface 75 and the horizontal cutting surface 76 are on the same side of the limit cone 72. The bottom of the box body can be placed on the horizontal cutting surface 76 of the limit cone 72, and the side of the box body can lean against the vertical cutting surface 75 of the guide rod 71 and the limit cone 72. At this time, the corners of the box body can extend into the space between the jacking rod 51 and the arm rod 32. When processing the corners of the box body, the box body will not interfere with the upper support base.

[0024] Obviously, without departing from the principle described in the present invention, several improvements or modifications made should be regarded as the protection scope of the present invention.
