Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a tool for testing the pressure resistance of a bearing sealing ring. Background Art

[0002] In order to increase the service life of the bearing, a sealing ring is set between the inner ring and the outer ring of the bearing. The sealing ring can prevent dust from entering the bearing. The existing bearing sealing rings include rubber sealing rings and metal sealing rings. Metal sealing rings need to be tested for bearings to determine whether the quality of the produced metal sealing rings meets the standards;

[0003] For example, patent application number CN202320766881.2 discloses a tooling for testing the pressure resistance of a bearing sealing ring. In this patent, the staff first installs two L-shaped support frames 102 on the test workbench by bolts, and then the staff places the bearing sealing ring body 5 to be tested between three rubber pads A202 and three rubber pads B402. Then the staff starts the electric telescopic rod 304. At this time, the three drive seats 301 drive the three clamping blocks 401 to move, thereby achieving simultaneous clamping of the three bearing sealing ring bodies 5, improving the efficiency of the pressure resistance test, and because the three rubber pads A202 are fixedly installed on the right side of the three support blocks 201, and the three rubber pads B402 are fixedly installed on the left side of the three clamping blocks 401, the friction between the three bearing sealing ring bodies 5 is increased, making the three bearing sealing ring bodies 5 more stable during the pressure resistance test;

[0004] During the use of this patent in the prior art, the bearing sealing ring may slip out when the clamping block clamps the bearing sealing ring. Due to the strong clamping force, the bearing sealing ring may pop out, posing a greater safety hazard. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a bearing seal ring pressure resistance test tool to solve the problem that the bearing seal ring may jump out and injure people in the prior art described in the background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a bearing seal ring pressure resistance test tool, comprising

[0007] Two covers are fixedly connected to the bottom plate;

[0008] Two movable plates are movably arranged on the bottom plate;

[0009] Two support plates are respectively fixedly connected to the moving plate, and a plurality of vertically arranged positioning plates are arranged on one side of the support plate corresponding to the cover body;

[0010] A plurality of limit plates are V-shaped and fixedly connected to the positioning plates;

[0011] A plurality of movable cylinders are respectively fixedly connected to positions corresponding to the limit plates on the cover body;

[0012] A plurality of clamping plates are V-shaped and fixedly connected to the output ends of the moving cylinders;

[0013] A plurality of baffles are respectively fixedly connected to the upper surface of the clamping plate.

[0014] Preferably: a double-extension shaft motor is fixedly connected to the vertical plate body of the base plate, and screws and guide rods are rotatably arranged between the vertical plate body of the base plate and the inner walls of the two cover bodies, and the output ends of the double-extension shaft motor are respectively fixedly connected to the two screws, and the two screws are respectively connected to the movable plate by threads, and the guide rod slides through the movable plate.

[0015] Preferably, the baffle is U-shaped.

[0016] Preferably, a layer of anti-slip rubber pad is provided on the opposite surfaces of the clamping plate and the limiting plate.

[0017] The beneficial effects of adopting the above technical solution are:

[0018] The movable plate set in the present application can drive the support plate to move, so that the support plate blocks the open end of the cover body, and the clamping plate and the limit plate can apply an extrusion force to the sealing ring on the positioning plate, so that the sealing ring can be squeezed, thereby detecting the performance of the sealing ring. The baffle in the present application can limit the sealing ring that pops out, and the cover body liquid can play a limiting role, thereby improving the safety of the detection.

[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3 In the first embodiment, a bearing seal ring pressure resistance test tool includes:

[0025] Two covers 50 are fixedly connected to the base plate 10;

[0026] Two movable plates 30 are movably disposed on the bottom plate 10;

[0027] Two support plates 41 are respectively fixedly connected to the moving plate 30, and a plurality of vertically arranged positioning plates 40 are arranged on one side of the support plate 41 corresponding to the cover body 50;

[0028] A plurality of limit plates 70 are V-shaped and fixedly connected to the positioning plates 40;

[0029] A plurality of movable cylinders 61 are respectively fixedly connected to positions of the cover body 50 corresponding to the limit plates 70;

[0030] A plurality of clamping plates 60 are V-shaped and fixedly connected to the output ends of the moving cylinders 61;

[0031] A plurality of baffles 80 are respectively fixedly connected to the upper surface of the clamping plate 60 .

[0032] This embodiment is implemented as follows:

[0033] When the present application is in use, the sealing ring is placed on the positioning plate 40, and then the movable plate 30 drives the support plate 41 to move, so that the movable plate 30 drives the support plate 41 to enter the cover body 50, and then the movable cylinder 61 drives the clamping plate 60 to move, so that the clamping plate 60 can clamp the sealing ring on the positioning plate 40, thereby realizing the detection of the sealing ring. When the sealing ring pops out during the clamping process, the cover body 50 and the support plate 41 can play a blocking role, and the baffle 80 plays a limiting role, thereby effectively ensuring the safety of the workers.

[0034] The advantage of the present application over the prior art is that it can improve the safety of detecting bearing sealing rings.

[0035] See also Figure 1 , 2 3. A double-extension shaft motor 20 is fixedly connected to the vertical plate body of the base plate 10. Screws 21 and guide rods 22 are rotatably arranged between the vertical plate body of the base plate 10 and the inner walls of the two cover bodies 50. The output ends of the double-extension shaft motor 20 are fixedly connected to the two screws 21 respectively. The two screws 21 are respectively connected to the movable plate 30 by threads, and the guide rod 22 slides through the movable plate 30.

[0036] The dual-axis motor 20 can drive the two screws 21 to rotate, so that the screws 21 can drive the moving plate 30 to move along the guide rods 22 on the bottom plate 10, thereby enabling the moving plate 30 to drive the supporting plate 41 to move.

[0037] See also Figure 2 , the baffle is cross-shaped;

[0038] The cross-shaped baffle can prevent the sealing ring from popping out in a larger range.

[0039] See also Figure 3 , the opposite surfaces of the clamping plate 60 and the limiting plate 70 are provided with a layer of anti-skid rubber pad;

[0040] The anti-skid rubber pad can increase the friction between the sealing ring and the clamping plate 60 and the limiting plate 70 .

[0041] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
