The circular hole and the sensor clamped on the fixing mechanism are coaxially arranged, and the diameter of the circular hole is greater than the outer diameter of the sensor. The opening assembly presents a cylindrical structure composed of a plurality of arc segments. The outer diameter of the cylindrical structure is smaller than the inner diameter of the rubber ring. The opening assembly extends downward through the cylinder, and the axis of the opening assembly is in the same straight line as the axis of the circular hole.

[0040] The opening assembly is connected with the expanding assembly, and under the action of the expanding assembly, the opening assembly has two states of being separated and dispersed in an arc segment and being combined in a cylindrical shape;

[0042] In this embodiment, the opening assembly of the cylindrical structure composed of a plurality of arc segments is provided, wherein the size of the cylindrical structure is smaller than the inner diameter of the rubber ring, so as to facilitate the sleeving of the rubber ring on the opening assembly. Then the opening assembly and the rubber ring are expanded as a whole by the expanding assembly, and the size of the overall expansion of the opening assembly and the rubber ring is determined by the outer diameter of the sensor; in addition, the diameter of the circular hole limits the maximum expansion range of the expanding assembly and the rubber ring, and only the diameter of the circular hole needs to be larger than the maximum diameter in the sensor, so that the expansion range of the opening assembly can be adjusted by the expanding assembly, thereby being suitable for the expansion work of the rubber ring of various outer diameter sensors. The sensor is clamped by the fixing mechanism directly below the cylindrical structure, and the two are coaxially arranged.

[0043] After the rubber ring is sleeved on the extrusion assembly, there are two ways to extrude the rubber ring to the sensor. The first way is that the bottom of the opening assembly is placed on the upper part of the sensor, and the extrusion assembly directly extrudes the rubber ring to the sensor; the second way is that the opening assembly needs to be sleeved on the sensor, and then the extrusion assembly extrudes the rubber ring to the sensor.

[0044] In the first way, the height of the moving plate is first adjusted by the power unit, so that the bottom end of the cylindrical structure is fitted with the top end of the sensor; then the rubber ring is extruded from the cylindrical structure to the sensor by the extrusion assembly, that is, the installation work of the rubber ring on the sensor is completed.

[0045] In the second way, the height of the moving plate is adjusted by the power unit, so that the bottom end of the cylindrical structure is fitted with the top end of the sensor; secondly, the opening assembly is expanded by the expanding assembly, and the height of the moving plate is continuously adjusted, so that the cylindrical structure is sleeved on the outside of the sensor; then the rubber ring is extruded from the cylindrical structure to the sensor by the extrusion assembly, that is, the installation work of the rubber ring on the sensor is completed.

[0046] Based on the above measures, the device has the characteristics of simple structure and low investment, and is suitable for early use in small processing plants; in addition, compared with manually sleeving the rubber sleeve on the sensor, the device does not need the workers to manually expand the rubber ring frequently, thereby reducing the labor intensity of the workers and improving the assembly efficiency of the rubber ring.

[0082] Specifically, the rack comprises a bottom plate 1-1 and a U-shaped frame 1-2 fixed vertically on the bottom plate, a vertical limiting sliding groove 1-3 is arranged on the U-shaped frame, and a fixing mechanism is arranged on the bottom plate. The power unit comprises a threaded rod 5-1 arranged vertically on the limiting sliding groove of the U-shaped frame, and a second motor 5-2 for driving the threaded rod to rotate; a second threaded hole 4-2 matched with the threaded rod is arranged on the moving plate; the two ends of the threaded rod are arranged on the bottom and the bottom of the U-shaped frame through bearings respectively, the top end of the threaded rod penetrates through the U-shaped frame and is connected with the output shaft of the second motor, and the moving plate is sleeved on the threaded rod and abuts against the inner wall of the limiting sliding groove.

[0083] The working process of the present application (taking four arc-shaped plates and the opening assembly sleeved on the sensor as an example):

[0084] Mainly includes the following steps:

[0085] 1. In operation, align the rubber ring with the annular shallow groove, start the first pneumatic telescopic rod, lower the circular table support, open the four arc-shaped plates, and make the rubber ring open and embed in the annular shallow groove. When the four arc-shaped plates are opened, the two pressing plates are pushed to the two sides, and the two pressing plates are tightly attached to the outer walls of the four arc-shaped plates under the action of the second spring.

[0086] 2. Put the sensor between the four T-shaped arc plates of the fixed structure, and start the first motor to complete the fixing work of the sensor.

[0087] 3. Start the second motor to drive the threaded rod to rotate, thereby driving the moving plate and the tensioning mechanism to move downward as a whole until the bottom end of the cylindrical structure abuts against the top of the sensor. Then, continue to lower the circular table support until the four arc-shaped plates wrap the top end of the sensor.

[0088] 4. Start the second pneumatic telescopic rod to move the two pressing plates downward, so that the two pressing plates can extrude the rubber ring downward to the outer wall of the sensor.

[0089] 5. After installation, start the second pneumatic telescopic rod again to make the two pressing plates rise and be sleeved on the outer walls of the four arc-shaped plates.

[0090] The above is only a preferred embodiment of the present application, and of course cannot limit the scope of the present application, therefore equivalent changes made within the scope of the present application patent application are still within the protection scope of the present application.
