TECHNICAL FIELD

[0001] The utility model relates to endoscope technical field, and specifically is a kind of endoscope snake bone circumferential forming device. BACKGROUND

[0002] Endoscope includes a snake bone assembly, which is composed of snake bones connected in sequence. By adjusting the positions of different snake bones, the rotation angle of the entire endoscope can be adjusted to facilitate the operation of the diagnostician.

[0003] The snake bones are connected, and a connecting sleeve needs to be installed at the end of the snake bone. As shown in Figure 6 The side of the connecting sleeve needs to be provided with two or four symmetrical planes to realize the connection.

[0004] The conventional connecting sleeve is integrally cast, which needs to open a special mold. Not only the process is complex, but also the production time is long, the efficiency is low, and the cost is high.

[0005] Therefore, how to overcome the above defects has become a problem to be solved by the technical personnel in the field. SUMMARY

[0006] To solve the technical problems in the background art, the utility model discloses an endoscope snake bone circumferential forming device.

[0011] The beneficial effects of the above setting are: connecting sleeve is round pipe shape before forming, only needs to be formed by round pipe cutting, then plane is formed by extruding by top block, so that the device compared to traditional mold, not only simple structure, low cost, but also high efficiency.

[0012] To improve the moving stability of top block, further design is: the upper end surface of support is also provided with linear guide rail;Top block is installed on the slider of linear guide rail.

[0013] When the connecting sleeve of different models is replaced, the corresponding top block also needs to be replaced; if the top block is directly connected to the slider of the linear guide rail, the replacement involves bolt disassembly, which is slow, based on this, further improvement lies in that the upper end of the slider of the linear guide rail is provided with a connecting block; the top block is horizontally inserted into the connecting block.

[0014] The conventional driving assembly needs to be provided with multiple corresponding top blocks, and the synchronism is poor, which leads to low precision of the connecting sleeve after forming, based on this, further improvement lies in that the driving assembly comprises a roller and a lifting assembly for driving the roller to lift; the connecting block is provided with a first driving slope located directly below the roller; the first driving slope is pressed by the roller to drive the connecting block to move close to the connecting sleeve.

[0015] Since the top block cannot be automatically reset after work, based on this, further improvement lies in that a fixing block is further installed on the support, and a connecting rod is threadedly connected to the connecting block through the fixing block; the outer end of the connecting rod is provided with a radially extending lug plate; a reset spring is sleeved with the connecting rod, one end of which abuts against the fixing block, and the other end of which abuts against the lug plate.

[0016] When the connecting sleeve of different diameters is replaced, the moving distance of the push rod also needs to be changed accordingly, such as replacing push rods of different lengths, which will lead to increased cost, based on this, further improvement lies in that a vertical guide column is installed on the support; a guide sleeve sleeved with the guide column is fixedly installed on the lifting plate; the driving end of the lifting assembly is fixedly connected to the lifting plate; a sliding groove is formed in the lower end surface of the lifting plate; a sliding plate is clamped in the sliding groove; the roller is installed on the sliding plate. In this way, the position of the sliding plate in the sliding groove is adjusted, the length of the roller acting on the first driving slope is adjusted, and thus the extension distance of the push rod is adjusted.

[0017] To further improve the adjustment range of the extension distance of the push rod, specifically, a second driving slope is further arranged on the connecting block and located opposite to the first driving slope; the inclination angles of the first driving slope and the second driving slope are different. In this way, the direction of the connecting block is changed, and the adjustment range of the extension distance of the push rod is changed by locating the second driving slope directly below the roller.

[0018] Since the connecting sleeve has high connection strength with the tooling column after deformation, it is difficult to be taken out from the tooling column, based on this, further improvement lies in that a stripper sleeve is further sleeved on the tooling column, and the stripper sleeve is located below the flat end surface; the connecting sleeve is separated from the tooling column by driving the stripper sleeve to ascend. The specific structure of the stripper sleeve lifting is that a radially extending driving rod is connected to the outer side of the stripper sleeve; a stripper plate is installed on the support and driven by a stripper cylinder to move horizontally; a driving groove is formed in one end of the stripper plate close to the driving rod, and the driving groove is obliquely downward and opposite to the driving rod.

[0019] The utility model discloses beneficial effect is: the connecting sleeve is the round pipe shape before forming, only needs to be formed through round pipe cutting, and then extrudes through the top block to make the plane forming, thereby making the device compared with the traditional mould, not only simple structure, low cost, and high efficiency still.
