The middle part of the plate 15 is provided with a plurality of second slide grooves 18 in a circumferential array; a slide post 19 is fixed to the bottom of the slider 17; the slide post 19 is rotatably and slidably connected to the inside of the second slide groove 18; a top block 110 is fixed to the top of the slider 17; a fixed rod 111 is fixed to the middle part of the movable plate 15; a gear ring 112 is rotatably connected to the top of the bottom plate 1; a connecting rod 113 is fixed to the top of the gear ring 112; the middle part of the connecting rod 113 is fixed to the top block 110; the gear ring 112 is concentrically arranged with the fixed plate 14 and the movable plate 15; a motor 114 is fixed to the top of the bottom plate 1; the output end of the motor 114 is fixed The gear 115 is connected to the gear 115; the gear 115 is meshed with the gear ring 112; when working, the half-axle of the automobile to be drilled is placed longitudinally between the multiple top blocks 110, and then the motor 114 is started to drive the gear 115 to rotate, and then the connecting rod 113 is driven to rotate by the cooperation of the gear 115 and the gear ring 112, thereby driving the movable plate 15 to rotate. When the movable plate 15 rotates, the intersection point of the first slide groove 16 and the second slide groove 18 will change position. At this time, the slide column 19 will move along the second slide groove 18, thereby driving the slider 17 to slide along the first slide groove 16, so that the multiple top blocks 110 move toward the middle half-axle of the automobile, so that Multiple top blocks 110 clamp the middle automobile half-axle, thereby increasing the stability of the automobile half-axle when drilling automobile half-axles of different diameters. This process is simply to drive multiple top blocks 110 to slide a short distance through the short operation of motor 114, which takes a short time. When drilling is completed, start the motor 114 to reverse and drive multiple top blocks 110 away from each other. At this time, the automobile half-axle with completed drilling can be easily removed. Through the above structure, automobile half-axles of different diameters can be clamped and fixed conveniently and quickly when drilling automobile half-axles of different diameters, and the clamping of the automobile half-axle can be quickly released after drilling is completed.
[0025] like Figures 1 to 5As shown, the top of the fixed plate 14 is fixedly connected to a top cover 2; the top cover 2 surrounds a plurality of top blocks 110 and is arranged inside; the bottom of the top cover 2 is fixedly connected to a baffle 21; the top edge of the baffle 21 is provided with a collecting groove 22; during operation, in the process of drilling the automobile half-axle, some debris will be thrown out from the end of the half-axle to the surroundings as the turning tool rotates, and some of the debris will be blocked by the top cover 2 and the baffle 21 when falling, and it is difficult for the debris to fall on the clamping assembly 13 and near the gear ring 112, thereby reducing the impact of the processing debris on the operation of the fixture.
[0026] like Figures 1 to 4 As shown, a plurality of rubber sleeves 3 are fixedly connected to one end of the top block 110 facing the center of the fixed plate 14; the plurality of rubber sleeves 3 are densely distributed at the end of the top block 110; when the plurality of top blocks 110 squeeze and clamp the middle automobile half-axle, the plurality of rubber sleeves 3 will contact the surface of the automobile half-axle and deform as the top block 110 squeezes. After the clamping is completed, the plurality of rubber sleeves 3 will fully contact the arc-shaped surfaces of the half-axles of different diameters and generate greater friction, thereby increasing the contact area of the squeezing and clamping when drilling automobile half-axles of different diameters, improving the clamping stability of automobile half-axles of different diameters, and reducing the occurrence of automobile half-axle self-rotation offset during drilling.
[0027] like Figures 1 to 4 As shown, a plurality of elastic wires 4 are fixedly connected to the interior of the rubber sleeve 3; both ends of the plurality of elastic wires 4 are embedded in the top block 110; during operation, when clamping the automobile half-axle, the plurality of elastic wires 4 are elastically deformed along with the rubber sleeve 3, and the deformed rubber sleeve 3 will fully contact the surfaces of the half-axles of different diameters. However, after the half-axle is removed, the plurality of rubber sleeves 3 may be tightly combined with each other, and the elastic force of the plurality of rubber sleeves 3 themselves may not be sufficient for restoration. At this time, the elastic wires 4 will drive the plurality of rubber sleeves 3 to restore during elastic restoration, so that when clamping half-axles of other diameters, the plurality of rubber sleeves 3 can be deformed again according to the diameter of the half-axle, and the contact area can be stably increased when clamping half-axles of different diameters.
[0028] like Figure 1 As shown, the top of the base plate 1 is provided with a plurality of limit columns 5 rotatably connected in a circular array; the plurality of limit columns 5 are located inside the gear ring 112 and are fitted with the inner wall of the gear ring 112; when working, the plurality of limit columns 5 will rotate with the rotation of the gear ring 112. When the gear ring 112 rotates, it will be subjected to the torsion from the connecting rod 113. The gear ring 112 will transmit part of the torsion to the base plate 1 through the rotating connection between the gear ring 112 and the base plate 1, and the other part will be transmitted to the plurality of limit columns 5 for bearing, thereby reducing the occurrence of stress deformation of the gear ring 112 and improving the service life of the device.
[0029] like Figure 1 As shown, a plurality of clamping assemblies 13 are installed in the middle of the bracket 12; the top cover 2 is fixed to the top of the uppermost fixed plate 14; during operation, when drilling the half-shaft, the half-shaft is clamped by multiple clamping assemblies 13, so that the end face of the half-shaft processing can stably face the turning tool, thereby reducing the occurrence of a decrease in drilling accuracy.
[0030] like Figure 5 As shown, a water-absorbing belt 6 is fixed to the bottom of the collecting tank 22; the height of the water-absorbing belt 6 is not higher than the top of the collecting tank 22; when drilling the half-axle, a blowing device is used to blow away the debris, so that the debris inside the collecting tank 22 can be easily blown out again. At this time, some liquid can be added to the inside of the collecting tank 22, and this part of the liquid is absorbed by the water-absorbing belt 6. When the debris falls in, the debris will be wetted and absorbed by the wet water-absorbing belt 6, thereby reducing the occurrence of debris flying around again.
[0031] When working, the automobile half-axle that needs to be drilled is placed longitudinally between the multiple top blocks 110, and then the motor 114 is started to drive the gear 115 to rotate, and then the connecting rod 113 is driven to rotate through the cooperation of the gear 115 and the gear ring 112, thereby driving the movable plate 15 to rotate. When the movable plate 15 rotates, the intersection point of the first slide groove 16 and the second slide groove 18 will change position. At this time, the slide column 19 will move along the second slide groove 18, and then drive the slider 17 to slide along the first slide groove 16, so that the multiple top blocks 110 move toward the middle automobile half-axle, so that the multiple top blocks 110 clamp the middle automobile half-axle, thereby increasing the stability of the automobile half-axle when drilling automobile half-axles of different diameters. This process is simply to drive the multiple top blocks 110 to slide a short distance through the short operation of the motor 114, which takes a short time. When the drilling is completed, the motor 114 is started to reverse, driving the multiple top blocks 110 When the plurality of top blocks 110 squeeze and clamp the middle automobile half-axle, the plurality of rubber sleeves 3 will contact the surface of the automobile half-axle and deform as the top blocks 110 squeeze. After the clamping is completed, the plurality of rubber sleeves 3 will fully contact the arc surfaces of the half-axles of different diameters and generate greater friction. When the automobile half-axle is clamped, the plurality of elastic wires 4 elastically deform along with the rubber sleeves 3, and the deformed rubber sleeves 3 will fully contact the surfaces of the half-axles of different diameters. However, after the half-axle is removed, the plurality of rubber sleeves 3 may be tightly combined with each other, and the elastic force of the plurality of rubber sleeves 3 themselves may not be sufficient for recovery. At this time, the elastic wires 4 will drive the plurality of rubber sleeves 3 to recover during the elastic recovery.
