Description

Technical Field

[0001] The utility model relates to the technical field of cam divider detection devices, in particular to a cam divider operation detection device. Background Art

[0002] Cam divider, also known as cam indexer or intermittent divider in engineering. It is a high-precision rotary device. In the prior art, the utility model patent with authorization announcement number CN218725316U, named a cam divider inspection platform, discloses a cam divider detection platform, which includes a platform plate, a mounting seat and a testing mechanism. The rotating shaft of the cam divider is driven to rotate by the testing mechanism, and the rotation speed always remains unchanged, which is convenient for detection. However, in the prior art, only one cam divider can be detected at a time. When multiple cam dividers need to be used, a large number of cam dividers need to be detected, which means that the efficiency of detecting one cam divider is low and the time required is long.

[0019] like Figure 1-5 As shown, the utility model includes a test bench 2 for a cam divider 3, which includes a frame 1, on which a test bench 2 is arranged, the test bench 2 includes a plurality of intermediate pads 5, on which a plurality of cam dividers 3 are fixed, and a rotating shaft 4 for driving the plurality of cam dividers 3 to operate simultaneously is arranged at the front end of the cam divider 3, on which a plurality of sprocket wheels 41 are mounted, and the sprocket wheels 41 and the driving shaft 31 of the cam divider 3 are linked and driven by a chain. For the convenience of description, it is assumed that Figure 1 The left and right directions are horizontal, and the up and down directions are longitudinal. The cam divider 3 is provided with a driving shaft 31, and the axes of the driving shafts 31 of the multiple cam dividers 3 are parallel to each other. Similarly, the axes of the rotating shaft 4 and the driving shaft 31 are parallel to each other. The rotating shaft 4 is driven to rotate by the driving device, thereby driving the multiple cam dividers 3 to operate simultaneously. After operation, the detection device can be used to detect whether the cam divider 3 trembles and shakes when running at high speed. After running for a period of time, the working temperature of the cam divider 3 is detected. If the working temperature of the cam divider 3 is too high, it means that there is a problem with the quality of the cam divider. At the same time, it can be observed whether the cam divider leaks oil during operation. By operating multiple cam dividers 3 at the same time, the detection efficiency of the cam divider 3 can be improved. At the same time, the cam divider 3 can be compared, and the different states of the cam divider 3 can be compared, thereby completing the detection of the cam divider 3.

[0020] like Figure 1-5As shown, an inverted T-shaped groove is provided between the intermediate pads 5. The inverted T-shaped groove is longitudinally arranged in the front-to-back direction. The inverted T-shaped groove is composed of a first groove located at the bottom and a second groove located at the top, and the width of the first groove in the left-right direction is greater than the width of the second groove in the left-right direction. A T-shaped nut is installed at the lower end of the cam divider 3, and the width of the lower end of the T-shaped nut is greater than the width of the upper end. By placing the T-shaped nut in the inverted T-shaped groove, the lower end of the T-shaped nut enters the first groove, and the upper end of the T-shaped nut enters the second groove, and the components at the upper end of the intermediate pad 5 can be fixed by fastening with the T-shaped nut and screws. The cam divider 3 is placed on the intermediate pad 5, and the position of the cam divider 3 is fixed by bolts and T-shaped nuts. A long baffle 6 is installed at the front end of each cam divider 3, and a short baffle 7 is installed at the rear end. The long baffle 6 and the end baffle respectively limit the position of the front and rear directions of the cam divider 3, thereby playing a limiting role. Two U-shaped holes are provided on the long baffle 6, and the U-shaped holes vertically penetrate the long baffle 6, and the width of the U-shaped hole in the left-right direction is greater than the width in the front-back direction. The two U-shaped holes are arranged on the left and right, and a T-shaped nut is provided under the long baffle 6, which is fastened to the T-shaped nut by screws passing through the U-shaped holes, thereby fastening the position of the long baffle 6. The setting of the two U-shaped holes sets two fixing points to fix the position of the long baffle 6. The short baffle 7 is located at the rear side of the cam divider 3, and two toad clamps 71 are installed on the upper end of the short baffle 7. The jaws of the toad clamp 71 are ahead, so that the jaws of the toad clamp 71 can fit with the rear end face of the cam divider 3, and the front and rear positions of the toad clamp 71 can be adjusted, thereby ensuring the stability of the cam divider 3 installed on the test bench 2.

[0021] like Figure 1-5As shown, the driving device includes a horizontally arranged rotating shaft 4, and a plurality of keyways 42 are arranged on the rotating shaft 4. A plurality of bearing seats 8 are installed on the test bench 2, and bearings are installed in the bearing seats 8. The rotating shaft 4 is installed in the bearing, and the position of the rotating shaft 4 is fixed by the bearing seats 8, while the rotating shaft 4 is supported during rotation. The plurality of bearing seats 8 are respectively arranged on the left and right sides and the middle of the rotating shaft 4 to ensure the stability of the rotating shaft 4 during rotation. A driving motor is installed in the frame 1. A pulley and a plurality of sprockets 41 are mounted on the rotating shaft 4, and the pulley is connected to the driving motor through a belt. The driving motor drives the pulley to rotate through the belt, and then drives the rotating shaft 4 to rotate. A plurality of sprockets 41 are mounted on the rotating shaft 4, and the position of the sprockets 41 corresponds to the position of the driving shaft 31 of the cam divider 3. A flat keyway is arranged on the inner diameter of the sprocket 41, and the sprocket 41 is installed between the flat keyway of the sprocket 41 and the keyway 42 of the rotating shaft 4 through a key 43 to fix the relative position between the rotating shaft 4 and the sprocket 41. In this embodiment, the rotating shaft 4 is provided with a plurality of key slots 42, and the length of the key slots 42 is much greater than the width of the key 43, so there is a large selection space for the installation position of the key 43. The key 43 is installed according to the required position of the sprocket 41, so the sprocket 41 can be installed at the required position of the rotating shaft 4 at will. When the length of the key slot 42 is longer than the length of the plurality of keys 43, a plurality of sprockets 41 can be installed in one key slot 42. By fitting a chain on the sprocket 41, and fitting the other end of the chain on the driving shaft 31 of the cam divider 3, when the sprocket 41 rotates, the chain drives the cam divider 3 to start running. In the utility model, four cam dividers 3 are installed on the test bench 2, and four sprocket wheels 41 corresponding to the driving shafts 31 of the cam dividers 3 are provided on the rotating shaft 4. The chains are mounted on the sprocket wheels 41 and the corresponding driving shafts 31. When the rotating shaft 4 rotates, the four cam dividers 3 are driven to operate simultaneously, thereby detecting the quality of the cam dividers 3, improving the detection efficiency, and forming a comparison between multiple cam dividers. When there is a cam divider 3 failure, it can be discovered as soon as possible, thereby ensuring the quality of the experiment. The test bench 2 is provided with multiple chain baffles 9, which block the chain position through the chain baffles 9, thereby ensuring safety during operation.
