5results about How to "Affect machining accuracy" patented technology

The present invention discloses a terminal processing device, which specifically relates to the field of terminal processing technology, including a base, a processing assembly is arranged on the base, the processing assembly includes a horizontal plate arranged on the top of the base, one end of the horizontal plate extends to the middle of the base and is rotatably connected to the base, and a position-adjustable slide plate is slidably connected to the horizontal plate. The present invention prevents the material belt from being displaced during transportation and processing, thereby affecting the processing accuracy. The second cutting and processing knife and the first cutting and processing knife can be appropriately deflected to process the material belt, and the cutting and processing efficiency is high and the continuity is strong. The second mold frame and the first mold frame can be displaced to different positions of the material belt, so that the material belt can be combined with the adjustment range of the deflection frame and the screw transmission module when processing the material belt to adapt to different processing requirements.

This utility model provides a clamping device for slender tubes with a large length-to-diameter ratio, belonging to the field of machining technology. The clamping device includes a clamping body, the right side of which is connected to an elastic clamping cone. A rolling element retainer passes through the elastic clamping cone, and the rolling element retainer has an elongated hole containing a rolling column. A clamping nut is threaded to the outer surface of the clamping body. The left side of the clamping body passes through a needle roller bearing, and the other end of the needle roller bearing is located within a limiting sleeve. By using clamping bolts, this utility model allows the rolling body to move and clamp the tube when the clamping nut is tightened, facilitating clamping or limiting the tube and preventing it from jumping during processing, thus affecting the processing accuracy. By using guide columns, the limiting sleeve can be limited, allowing the limiting sleeve to move stably and preventing deviation during movement.

The invention discloses a cutting device and method for automobile air conditioner plastic part machining, and relates to the technical field of plastic part cutting machining. According to the cutting device and method for machining the plastic parts of the automobile air conditioners, the cutting device comprises a shell and a cutting tool bit which is arranged in the shell and used for cutting the plastic parts of the automobile air conditioners, and an electric push rod is fixed in the shell; a cutting assembly used for cutting the automobile air conditioner plastic part and a maintaining assembly used for keeping the flatness of a cutting tool bit are arranged in the shell, the cutting assembly comprises a supporting column, and one end of the supporting column is detachably connected with the cutting tool bit and used for providing supporting force for the cutting tool bit; the surface quality and the size precision of the automobile air conditioner plastic parts are prevented from being affected, the interval duration of cutting machining of each cutting tool bit is prolonged, the cooling time of the cutting tool bits is prolonged, and therefore the product quality of the automobile air conditioner plastic parts obtained after cutting machining is improved.

This utility model discloses an automotive wiring harness welding device, relating to the field of welding equipment. It includes a machine body with a worktable inside. An electric telescopic rod is mounted above the worktable, and a welding head is fixedly installed at the bottom of the electric telescopic rod. A partition is located at the lower end of the electric telescopic rod, and a cleaning mechanism is located above the partition. The cleaning mechanism includes an air pump, which is fixedly installed on both sides of the partition. When the operator welds the metal wiring harness, they first operate the automatic telescopic rod to move it down. A striking rod fixedly connected to the bottom of the welding head moves down along with the automatic telescopic rod. At this time, the striking rod strikes a seesaw, causing the other end of the seesaw to lift a protective plate, thereby preventing sparks or other impurities such as broken welding wire from being ejected onto the operator's body and endangering their health. The protective plate improves the safety performance of the automotive wiring harness welding machine.

The utility model provides a minimum quantity lubrication supply device and a numerical control machine tool. The minimum quantity lubrication supply device comprises a machine tool spindle with a containing groove in one end. The cutter is mounted on the machine tool spindle and internally provided with a particle supply channel; the conveying pipeline is installed in the machine tool spindle, the output end of the conveying pipeline is connected into the containing groove, and an inner-layer channel and an outer-layer channel which are not communicated with each other are arranged in the conveying pipeline; the gas inlet and the lubricating oil inlet are formed in the machine tool spindle and communicate with the outer-layer channel and the inner-layer channel through a gas conveying channel and an oil conveying channel correspondingly; the sealing bracket is arranged in the accommodating groove and is provided with a mixing cavity for connecting the inner-layer channel and the outer-layer channel; the premixing unit is arranged in the mixing cavity, a premixing cavity is formed in the premixing unit, one end of the premixing unit is provided with an oil gas inlet communicated with the premixing cavity, and the other end of the premixing unit is provided with a first filtering structure communicated with the premixing cavity; gas and lubricating oil are input into the premixing cavity through the gas conveying channel and the oil conveying channel to be premixed, and an oil-gas mixture forms aerial fog particles in the mixing cavity through the first filtering structure and is output out of the tool through the particle supply channel.
