Description

Technical Field

[0001] This utility model relates to the field of eccentric shaft detection technology, specifically an eccentric shaft detection device. Background Technology

[0002] An eccentric shaft testing device is used to accurately measure various geometric parameters of an eccentric shaft to determine whether it meets design and usage requirements. An eccentric shaft is a type of shaft part whose axis does not coincide with its center of rotation. It is widely used in equipment such as engines and compressors, and its manufacturing precision directly affects the performance and reliability of the equipment.

[0003] An investigation revealed that a utility model patent (publication number: CN221992559U) discloses an eccentric shaft detection device, comprising a detection platform with two support plates slidably connected to it. The platform is connected to a drive assembly for driving the two support plates to slide towards or away from each other. A turntable is rotatably connected to one side of each support plate. A first drive member for driving the turntable to rotate is connected to each support plate. A clamping mechanism for clamping the eccentric shaft is connected to the turntable. A dial indicator is connected to the detection platform and positioned between the two support plates. This application places the eccentric shaft in a corresponding position, and the drive assembly drives the two support plates to move towards each other. When the turntable moves to the corresponding position, the clamping mechanism clamps both ends of the eccentric shaft, thereby improving the stability of the eccentric shaft placed on the turntable and increasing the accuracy of eccentric shaft detection.

[0004] Although the aforementioned patent uses components such as support plates, drive turntables, and drive components to quickly clamp the shaft during the eccentric shaft testing process through the cooperation of these components, ensuring its stability during testing, the outer wall of the shaft is prone to dust accumulation because the operator needs to place the shaft on the clamping table during the testing process. This can affect the accuracy and precision of the testing.

[0005] Therefore, this utility model provides an eccentric shaft detection device to solve the above problems. Utility Model Content

Synchronous cleaning can improve the comprehensiveness and effectiveness of the cleaning. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides an eccentric shaft detection device, such as Figures 1-4As shown, the eccentric shaft detection device includes a detection machine 1 and a cleaning assembly. The cleaning assembly includes a device frame 2 installed on the outer surface of the detection machine 1. A pneumatic motor 3 is installed inside the equipment frame 2. The output end of the pneumatic motor 3 is coaxially driven by a reciprocating screw 4 through a coupling. A rotating seat 5 is fixedly connected to the outer wall of the testing machine 1 corresponding to the end of the reciprocating screw 4. The end of the reciprocating screw 4 rotates on the inner wall of the rotating seat 5. A cleaning table 6 is threaded onto the outer wall of the reciprocating screw 4. The cleaning table 6 is hollow and a connecting plate 7 is fixedly connected to its bottom end. A soft brush 8 is fixedly connected to the bottom end of the connecting plate 7.

[0023] The cleaning assembly also includes an adsorption seat 9 fixedly connected to the bottom of the cleaning table 6. An adsorption tube 10 is fixedly connected to the outer wall of the adsorption seat 9. There are several adsorption tubes 10. A vacuum generator 11 is fixedly connected to one side of the outer surface of the detection machine 1.

[0026] Specifically, through the configuration of the cleaning components, the various parts work together to quickly clean the shaft during the feeding process. The soft brush 8, in conjunction with the reciprocating cleaning table 6, removes dust and impurities adhering to its outer wall, preventing dust from affecting the stability and accuracy of shaft detection.

This allows the soft brush 8 to clean the shaft. While the air pump 13 drives the pneumatic motor 3, its other output end, through the negative pressure pipe 12 and the vacuum generator 11, generates negative pressure suction to adsorb the dust from multiple adsorption pipes 10 on the outer wall of the cleaning table 6, thus quickly adsorbing the cleaned dust and improving the efficiency of dust removal. The conveying speed of the pneumatic motor 3 can be adjusted through the curved pipe 16 and the rotary valve on its outer wall to adapt to different cleaning rhythms.

[0029] Specifically, the feed rack 17 can work with the conveyor belt 18 to automatically feed and transport the shaft, which facilitates the testing machine 1 to quickly test the shaft. The multiple observation windows 19 make it easier for operators to record the testing process and improve the integrity of the data.

[0030] The testing machine 1 has two discharge racks 20 installed on one side wall of the observation window 19. The inner wall of the discharge rack 20 is equipped with a discharge belt 21.

[0031] The top of the testing machine 1 is fixedly connected with an indicator light 22, and there are multiple indicator lights 22.

[0032] The bottom end of the testing machine 1 is fixedly connected to a support frame 23, and there are several support frames 23.

[0034] Specifically, the two discharge racks 20 facilitate the conveying of the shaft according to the different test results, making it easier for operators to quickly identify qualified products. The indicator lights 22 facilitate the rapid display of test results, which can help remind operators. The maintenance cabinet 24 facilitates the daily maintenance and repair of the testing machine 1.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
