Description

Technical Field

[0001] The utility model belongs to the field of production equipment, in particular to a reducer rollover fixing device and a multi-station pressing machine. Background Art

[0002] The multi-station pressing machine includes a main shaft located in the middle of the pressing machine, and a plurality of pressing stations arranged in a circular array around the main shaft. The component used for pressing is arranged above one of the pressing stations. After a pressing action, the motor drives the main shaft to rotate a certain angle, so that the next pressing station comes under the component used for pressing and performs the next pressing action, and so on, in a continuous cycle.

[0003] like Figure 1 As shown, the main shaft 8 of the multi-station press machine is driven by the motor 11 driving the reducer 1, and the output shaft 2 of the reducer 1 is connected to the main shaft 8 through the transmission chain 10. When the motor 11 drives the main shaft 8 to rotate, the transmission chain 10 is tightened, and the output shaft 2 of the reducer 1 is subjected to radial force. In order to fix the reducer 1, a reducer fixing device is provided on the side wall of the reducer 1 to connect it to the chassis of the multi-station press machine. However, over time, under the action of the radial force brought by each rotation, the side of the reducer 1 away from the main shaft 8 will become loose, causing each rotation to cause the reducer 1 to tip over toward the side close to the main shaft 8, thereby moving away from the frame, affecting the structural stability of the machine during operation. Utility Model Content

[0004] In order to solve the above deficiencies existing in the prior art, the utility model aims to provide a reducer rollover fixing device to achieve the purpose of preventing the reducer from rolling over. The utility model also aims to provide a multi-station pressing machine to fix the reducer to achieve the purpose of making the operation process of the machine more stable.

[0009] As a limitation of the present invention: the fixing hole is an oblong hole arranged along the direction in which the fixing pressure plate extends out of the reducer.

[0010] As a limitation of the present invention: the first fixing component is a threaded fastener.

[0011] The utility model also discloses a multi-station pressing machine, comprising a frame, on which a main shaft and a plurality of pressing stations arranged in a circumferential array in the circumferential direction of the main shaft are arranged. The main shaft is driven by a motor fixed to a bottom plate of the frame and a reducer fixed to the bottom plate of the frame, and the output shaft of the reducer is connected to the main shaft through a transmission chain or a transmission belt.

[0022] Example 1

[0023] In this embodiment, Figure 2 The figure shows a reducer rollover fixing device. The reducer rollover fixing device in this embodiment can be used to fix any reducer 1 with rollover phenomenon. One of the reducers 1 is used as an example for explanation. The lower end face of the reducer 1 is fixed on the frame bottom plate 9, and the output shaft 2 of the reducer 1 extends from the rear side of the upper end face of the reducer 1 along the height direction. The main shaft 8 connected to the output shaft 2 is arranged on the rear side of the reducer 1 (not shown in the figure). Therefore, after a period of use, the front side of the reducer 1 will roll upward at the beginning of each action. The reducer rollover fixing device in this embodiment is used to improve the above-mentioned rollover phenomenon.

[0024] Specifically, the reducer rollover fixing device includes a fixed pressure plate 3, which is arranged on a surface corresponding to the rollover direction of the reducer 1. The reducer 1 rolls upward, so the surface corresponding to the rollover direction of the reducer 1 here refers to the upper end surface, that is, the fixed pressure plate 3 in this embodiment is arranged on the upper end surface of the reducer 1. The end of the fixed pressure plate 3 away from the rollover of the reducer 1 is fixed to the reducer 1 through the first fixing component 4, and the end of the fixed pressure plate 3 facing the rollover of the reducer 1 is fixed to the frame for setting the reducer 1 through the second fixing component. In this embodiment, the front end of the fixed pressure plate 3 is fixed to the upper end surface of the reducer 1 through the first fixing component 4, and the rear end of the fixed pressure plate 3 is fixed to the frame bottom plate 9 through the second fixing component.

[0025] Furthermore, the first fixing component 4 is a hexagon socket bolt, and the fixed pressure plate 3 is provided with an inner concave arc matching the main shaft 8 at one end facing the main shaft 8, and a plurality of threaded through holes matching the inner hexagon socket bolts are provided along the circumference of the inner concave arc, and the rear end of the fixed pressure plate 3 is directly fixed to the upper end surface of the reducer 1 by using the inner hexagon socket bolt. Of course, the first fixing component 4 can also be other threaded fasteners, such as screws, etc.

[0026] The front end of the fixed pressure plate 3 extends out of the reducer 1, and two fixing holes 5 for installing the second fixing component are provided in the part extending out of the reducer 1. The second fixing component is provided with two groups, including studs 6. The upper ends of the studs 6 extend through the two fixing holes 5 respectively, and the lower ends of the studs 6 extend through the frame bottom plate 9. The two through ends of the studs 6 are detachably fixed with anti-loosening nuts 7 adapted thereto. In this embodiment, the anti-loosening nuts 7 are realized by a double nut structure, which can effectively prevent the second fixing component from loosening and ensure the stability of the structure. The fixing hole 5 is an oblong hole provided along the direction in which the fixed pressure plate 3 extends out of the reducer 1, which is convenient for installation and debugging and can improve adaptability. Of course, the second fixing component can also use other threaded fasteners, such as bolts and nuts, as long as one end of the threaded fastener is provided through the fixing hole 5 and the other end of the threaded fastener is provided through the frame bottom plate 9, so that the reducer 1 can be clamped by the threaded fastener.

[0027] Example 2

[0028] In this embodiment, Figure 3 As shown, a multi-station pressing machine includes a frame, on which a main shaft 8 and a plurality of pressing stations (not shown in the figure) are arranged in a circular array around the main shaft 8. The main shaft 8 is driven by a motor 11 fixed to the bottom plate 9 of the frame to drive a reducer 1 fixed to the bottom plate 9 of the frame, and the output shaft 2 of the reducer 1 is connected to the main shaft 8 through a transmission chain 10 or a transmission belt. Since the main shaft 8 is arranged on the rear side of the reducer 1 and the output shaft 2 of the reducer 1 extends upward, the front side of the reducer 1 will flip upward at the beginning of each action, and the reducer 1 is provided with a reducer flip fixing device in Example 1.

[0029] Among them, the fixed pressure plate 3 is arranged on the upper end surface of the reducer 1, the rear end of the fixed pressure plate 3 is fixed to the reducer 1 near the main shaft 8 through the first fixing component 4, and the front end of the fixed pressure plate 3 is fixed to the frame bottom plate 9 through the second fixing component.

[0030] When the multi-station pressing machine is working and the front side of the reducer 1 has a tendency to tip over, the fixed pressing plate 3 clamps the front end of the reducer 1 on the bottom plate of the frame, so the reducer 1 remains stable and avoids tipping over.
