Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a detection device for a universal shaft type clamping device. Background Art

[0002] In large steel enterprises and heavy industrial enterprises, rolling mill equipment is a relatively important equipment component. The transmission part of the rolling mill uses a universal shaft to drive the working roll. Some rolling mills use different hole types in different rolling passes, which requires the universal shaft of the working roll to have a retractable function, which highlights the importance of the shaft head clamping device. The shaft head clamping device can ensure that the universal shaft and the roll can be locked. When there is a problem with the shaft head clamping, the roll cannot be locked, which will affect the movement of the rolling mill and the roll changing procedure of the rolling mill.

[0003] In the process of testing the universal shaft head clamping device, the universal shaft needs to be positioned and clamped. When positioning universal shafts of different specifications and types, the clamping plate needs to be replaced with a type that is compatible with it, so as to better achieve the positioning of the universal shaft. However, the clamping plates currently on the market are often installed by fasteners such as bolts. This installation method takes a long time to install the clamping plates, which is not convenient for users to replace, thereby reducing the user's detection efficiency of the universal shaft head clamping device. Utility Model Content

[0007] In addition, a preferred structure is that screw rod pairs are movably provided on both sides of the screw rod positioning mechanism, and the top of the screw rod pair extends out from the screw rod groove and is fixedly connected to the main splint.

[0011] In addition, a preferred structure is that a female limit cavity is opened on the mounting member, and when the mounting member is located in the mounting cavity, the sub-limit cavity is adapted and aligned with the female limit cavity.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-6 A detection device for a universal shaft clamping device includes a detection device body 1, a screw slot 11 is provided on the top of the detection device body 1, a screw positioning mechanism 3 is provided in the screw slot 11, and main plates 2 are movably provided on both sides of the screw positioning mechanism 3. A detachable auxiliary plate 4 is installed on the main plate 2, and a plurality of mounting parts 41 are fixedly provided on the auxiliary plate 4. The main plate 2 is adapted to have a mounting cavity 21 corresponding to the mounting parts 41, and one end of the mounting cavity 21 is closed, and a plurality of limit columns 6 are movably provided in the main plate 2. The detection of the universal shaft head clamping device can be realized by the detection device body 1, and it is worth noting that the specific structure of the detection device body 1 and its working mode are both existing technologies currently disclosed on the market, and they do not belong to the main technical problems to be solved in the present technical solution, so they are not elaborated in the present utility model.

[0022] Among them, both sides of the screw positioning mechanism 3 are movably provided with screw pairs 31, and the top of the screw pair 31 extends out from the screw slot 11 and is fixedly connected to the main clamping plate 2. The screw positioning mechanism 3 is a bidirectional screw, which is driven by a driving motor and drives the screw pairs 31 on both sides of the bidirectional screw to move, thereby driving the main clamping plates 2 on both sides to move and clamp. This is a prior art, so it is not elaborated.

[0023] A plurality of sub-limiting cavities 22 are provided downwardly on the top of the main plate 2, and the sub-limiting cavities 22 are communicated with the installation cavity 21. A plurality of guide columns 23 are arranged transversely in the sub-limiting cavities 22, and the limiting column 6 moves in the sub-limiting cavities 22 through the guide columns 23, and a top seat 61 is fixedly arranged on the top of the limiting column 6. The limiting column 6 can be guided by the arrangement of the guide columns 23.

[0024] Among them, a fixing seat 5 is fixedly arranged at the top of the main plate 2 behind the sub-limiting cavity 22, and a plurality of springs 51 are installed on the fixing seat 5, and the other ends of the springs 51 are connected to the top seat 61. Through the arrangement of the springs 51, the top seat 61 can be pushed, thereby realizing the pushing of the limiting column 6.

[0025] The mounting member 41 is provided with a female limiting cavity 42. When the mounting member 41 is located in the mounting cavity 21, the sub-limiting cavity 22 is aligned with the female limiting cavity 42. By clamping the limiting column 6 in the female limiting cavity 42 in the mounting member 41, the mounting member 41 can be clamped and fixed, so that the auxiliary clamping plate 4 can be fixed by the mounting member 41.

[0026] In this embodiment, by setting the screw positioning mechanism 3, the user can clamp the cardan shaft through the auxiliary clamping plate 4 on the main clamping plate 2, so that the cardan shaft can be detected through the detection device body 1. In addition, the auxiliary clamping plate 4 can be replaced, and the user can replace the auxiliary clamping plate 4 adapted to the type of the cardan shaft to be detected, thereby ensuring the positioning effect of the cardan shaft.

[0027] Furthermore, when the user needs to install the secondary clamping plate 4, he only needs to insert the mounting piece 41 on the secondary clamping plate 4 into the mounting cavity 21 on the main clamping plate 2. Before the mounting piece 41 is inserted, the user needs to push the top seat 61 outward, so that the limiting column 6 can leave the mounting cavity 21 and return to the secondary limiting cavity 22, and then the mounting piece 41 can be smoothly inserted into the mounting cavity 21.

[0028] When the user inserts the mounting member 41 into the mounting cavity 21, the female limiting cavity 42 on the mounting member 41 is aligned with the sub-limiting cavity 22 in the main clamping plate 2. At this time, the user only needs to loosen the top seat 61, and the top seat 61 can automatically move and reset due to the elastic force of the spring 51. At this time, the limiting column 6 can move into the female limiting cavity 42 on the mounting member 41, so that the mounting member 41 can be fixed, and the installation of the auxiliary clamping plate 4 is completed.

[0029] Furthermore, when the user needs to remove the auxiliary splint 4, he only needs to push the top seat 61 on the top of the main splint 2 outward. At this time, the limiting column 6 leaves the main limiting cavity 42 and enters the sub-limiting cavity 22. At this time, the user can remove the auxiliary splint 4.

[0030] In the utility model, the universal joint shaft can be clamped by setting the auxiliary clamping plate 4 on the main clamping plate 2, and then the universal joint shaft clamping device can be detected through the detection device body 1, and the auxiliary clamping plate 4 can be quickly assembled through the clamping arrangement between the mounting member 41 and the mounting cavity 21. This makes it convenient for users to easily replace the auxiliary clamping plate 4 when they need to clamp different types of universal joints, thereby improving the user's detection efficiency of the universal joint shaft clamping device.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
