Background
Among the hardware tools, the monkey wrench is a very widely used hand tool. The existing adjustable spanner in China is manufactured by processes one by one. The manufacturing method has the defects of low production efficiency, high labor intensity, difficult control of product quality and the like. And the traditional manual operation has large labor amount and more transition conversion references among working procedures, so that the accumulated error is increased, the matching quality after processing is seriously influenced, and the high-quality requirement of a high-end market is hardly met. Referring to fig. 1, the adjustable wrench is composed of three major components, namely a wrench body 102, a movable tongue 100 and a worm 101, wherein the wrench body 102 is used as a main component, and the machining precision of the wrench body directly influences the appearance and the usability of the adjustable wrench. In the current mode of production, the blank of the wrench body 102 is machined from the profile material, typically by isothermal swaging, and then the mating surfaces are machined to meet the final machining requirements of the mating surfaces. Referring to fig. 2, the key processing surfaces of the wrench body are: a wrench body opening surface 106, a middle groove 105, a big hole 104 and a small hole 103. The processing quality of the wrench body opening surface 106 directly influences the matching with the movable tongue opening surface. If the processing quality of the wrench body opening surface 106 is too low, the matching surface of the wrench body 102 and the movable tongue 100 is irregular, unparallel or fractured, and meanwhile, the wrench body opening surface 106 is also a working surface directly contacted with a bolt or a nut, and the processing quality greatly affects the use performance of the wrench. The middle slot 105 and the large hole 104 are matching surfaces for ensuring the normal sliding of the movable tongue 100 in the wrench body 102, and the processing quality directly determines whether the wrench is clamped or not in the opening and closing process. The small hole 103 is used as an installation hole of the central shaft of the worm 101, and the processing quality of the small hole also meets the installation precision requirement of the central shaft of the worm 101. The existing distributed processing production mode directly restricts the improvement of production quality and production efficiency because materials are converted for many times between working procedures.
Referring to fig. 3, a wrench machine tool adopts an eight-station rotary worktable type production mode, each station simultaneously clamps two workpieces through a hydraulic power clamp 122, and the workpieces are sequentially fed into each station for machining through the rotation of the worktable. The station 111 No. 1 is a part taking and placing station, and is used for placing a workpiece to be processed into an operation worker or a manipulator and taking out the processed workpiece. The No. 2 station 112 and the No. 3 station 113 are processing stations of the wrench body opening surface 106. The processing of the wrench body opening surface 106 adopts a vertical installation transverse cutting mode of a formed milling cutter to process, and three processing surfaces of the wrench body opening surface are processed simultaneously. No. 4 station 114, No. 5 station 115 and No. 6 station 116 are wrench body large hole 104 processing stations, wherein No. 4 station 114 adopts a violent drilling processing mode to pre-drill large holes, and guide holes are pre-drilled for processing No. 5 station 115 and No. 6 station 116. Station No. 5 115 and station No. 6 116 are then machined using conventional high speed twist drills. The No. 7 station 117 is a processing station of the spanner body small hole 103 and is processed in a horizontal transverse feeding mode. No. 8 station 118 is a machining station for a middle groove 105 of the wrench body, and the middle groove of the wrench body is machined in a transverse feeding mode of transversely installing a sheet type milling cutter.
In order to realize the automatic machining of the wrench machining tool shown in fig. 3, a control system is needed to control the servo feeding system, the main shaft system, the hydraulic rotary table and the hydraulic power clamp of the machine tool, so that the servo feeding system, the main shaft system, the hydraulic rotary table and the hydraulic power clamp can act in a coordinated manner according to the production process requirements of the wrench body to complete the automatic production machining work of the wrench body.
