Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and fig. 2, the processing apparatus includes a machine base 1, a carrier plate 2 slidably connected to the machine base 1, and a motor 3 disposed on the carrier plate 2, the machine base 1 is further provided with a hydraulic cylinder 4, a push rod of the hydraulic cylinder 4 is fixedly connected to the carrier plate 2, an output shaft of the motor 3 is connected to an installation shaft 5, the output shaft of the motor 3 is provided with a jack 31, the upper end of the installation shaft 5 is provided with a plug 33 adapted to the jack 31 and an outer sleeve 51 located outside the plug 33, the output shaft of the motor 3 is inserted between the plug 33 and the outer sleeve 51, the plug 33 is connected to the jack 31 through a spline, an outer wall surface of the output shaft of the motor 3 is provided with a ring groove 32, the outer sleeve 51 is uniformly provided with a plurality of first positioning holes 52 corresponding to the ring groove 32 in a circumferential direction, a first protrusion 53 is slidably connected to the first positioning hole 52, an inner end of the first protrusion, the upper surface of the first bump 53 is provided with a first inclined surface 55, the outer sleeve 51 is provided with a plurality of guide holes 56 corresponding to the first positioning holes 52 one by one, a guide rod 57 is inserted into each guide hole 56, the lower end of the guide rod 57 is provided with a second inclined surface 58 matched with the first inclined surface 55, the guide rod 57 moves downwards to drive the first bump 53 to move towards the outer side of the first positioning hole 52, and the first positioning hole 52 is internally provided with a compression spring 59 driving the first bump 53 to move towards the inner side.
Through the cooperation of annular 32 and first lug 53, make and install the dismouting between the output shaft of axle 5 and motor 3, guide bar 57 moves down compression spring 59, makes first lug 53 move outward, realizes the separation between installation axle 5 and the motor 3 output shaft, and the dismouting is very light simple, and the workman only needs the dismouting that the installation axle 5 can be accomplished in several seconds, and efficiency improves greatly.
Because the guide bar 57 for controlling the separation between the output shaft of the motor 3 and the installation shaft 5 is positioned at the top end of the installation shaft 5, and is far away from the processing part at the lower end of the installation shaft 5, the processing temperature is relatively low, the disassembly can be completed without cooling, the disassembly process does not need the labor-consuming operation of workers, and the unreliable condition that the installation shaft 5 is loosened does not exist.
Each guide rod 57 is fixedly connected to a pressure plate 34, and the pressure plate 34 is located above the outer casing 51. The guide bar stretches out the longer distance of installation axle upper end, makes the clamp plate keep away from the installation axle, and the clamp plate receives the thematic influence of processing friction less, the operation of being convenient for.
The base 1 is provided with a die holder 61 matched with a workpiece to be processed, the base 1 is transversely provided with a plurality of threaded holes, the threaded holes are internally threaded with a compression screw 62, and the inner side of the compression screw 62 can abut against the workpiece to be processed. The inner end of the compression screw is provided with a fan-shaped pressing sheet for extruding the outer side wall of a workpiece, the end cover of the valve body is taken as the workpiece in the drawing, and the processed inner hole is a valve hole on the valve body.
