Description

Technical Field

[0001] The utility model belongs to the technical field of roller shaft processing, and more specifically, particularly relates to a roller shaft processing fixture. Background Art

[0002] When processing the roller shaft, it is necessary to perform milling on both ends of the roller shaft. When using a milling machine to process the roller shaft, it is generally necessary to use a fixture to clamp the roller shaft, and then use a milling cutter to process both ends of the roller shaft.

[0003] The utility model with the existing application number 201420706034.8 discloses a roller shaft groove flat processing fixture, including a support plate, a first fixed plate, a roller shaft, and a fixture. A first V-shaped groove is provided in the middle of the upper surface of the first fixed plate, and a first through hole is provided in the upper left and lower right parts of the upper surface respectively. The first fixed plate is fixed to the support plate by a first bolt passing through the first through hole. A fixture is provided on the left side of the first V-shaped groove, and a U-shaped groove is provided in the middle of the upper surface of the fixture. The shape of the U-shaped groove is adapted to the flat square at one end of the roller shaft. Two second through holes are provided at the lower part of the front end face of the fixture, and the fixture is fixed to the left side of the fixing plate by a second bolt passing through the second through hole. The flat end of the roller shaft is stuck in the U-shaped groove, and the other end is fixed in the second V-shaped groove of the second fixed plate. The utility model quickly ensures the consistency of the direction of the flat processing at both ends of the roller shaft flat groove processing, improves work efficiency, has a simple structure, low cost, and is suitable for practical use.

[0004] Based on the above, when clamping the roller shaft, workers usually place the roller shaft inside the clamp, and then the clamp clamps the roller shaft driven by the cylinder. However, due to the small debris generated during the processing of the roller shaft, it will adhere to the inside of the clamp, causing the roller shaft to tilt when placed, resulting in errors in the groove flatness at both ends of the roller shaft, affecting the production quality of the roller shaft.

The clamping cylinder is opened. The clamping cylinder clamps the shielding scraper. When the shielding scraper is processed, the shielding scraper is taken out. At this time, the shielding scraper moves upwards under the action of the protection reset spring. The upward movement of the shielding scraper can clean the debris inside the clamping fixture. At the same time, by adjusting the setting of the connecting plate, the shielding scraper can be suitable for roller shafts of different diameters, thereby increasing the application range of the entire clamp.

[0035] The utility model adopts the setting of the clamping detection mechanism, when the operating plate is pressed downward, the detection connection slider moves downward under the action of the detection extrusion spring, and the two groups of detection trigger plates are respectively overlapped on the top of the operating plate. When the roller shaft is clamped, the left and right ends of the roller shaft are tilted. At this time, the operating plate at the higher end of the roller shaft moves upward, and the operating plate moves upward to squeeze the detection trigger plate on the corresponding side. The detection trigger plate is squeezed to drive the detection connection shaft to rotate, and the rotation of the detection connection shaft drives the detection indicator needle to rotate. When the detection indicator needle rotates, the scale of the detection indicator disk changes. The worker can adjust the state of the roller shaft according to the change of the angle of the detection indicator needle, thereby ensuring the horizontal placement of the roller shaft, avoiding the tilt of the roller shaft, and ensuring the production and processing quality of the roller shaft.
