Description

High-precision worm shaft deburring machine easy to adjust Technical Field The invention relates to the technical field of worm shaft processing equipment, in particular to a high-precision worm shaft deburring machine easy to adjust. Background The worm shaft is used as a common transmission part, burrs often appear in the machining process of the worm shaft, the burrs not only affect the appearance of the worm shaft and reduce the quality of the worm shaft, but also seriously affect the transmission efficiency in the use process, and therefore, the deburring process is a process necessary for machining the worm shaft. At present, mainly through burr machine deburring, current burr machine generally carries out the burring to the worm axle through grinding wheel grinding machanism, but grinding wheel grinding machanism's structure sets up unreasonably, can't adjust grinding wheel driving motor's every single move angle during operation, lead to the use limitation stronger, can't adapt to not unidimensional worm axle work piece, in addition, because its grinding wheel grinding machanism adopts the cylinder to carry out lifting control, also there is the defect that motion precision is lower, stability is relatively poor, moreover, because the cylinder is fixed stroke generally, when the emery wheel appears wearing and tearing, the cylinder can't carry out position automatic compensation to the emery wheel, the machining precision of product has been reduced. Chinese patent CN106826443B discloses an automatic deburring machine for a worm shaft, wherein the worm shaft is pushed onto a feeding belt through a pushing cylinder and a pushing rod, then the feeding belt transports the worm shaft to a workpiece clamping position, a lifting cylinder works to push a jacking block to drive the worm shaft to lift, when the worm shaft is lifted to a certain height, the jacking block is contacted with a triangle belt, then the triangle belt drives the worm shaft to rotate, and meanwhile, a grinding wheel grinding assembly is controlled to be close to the worm shaft for grinding. According to the scheme, the grinding wheel polishing assembly can be conveniently and accurately adjusted in position in a certain range through the cooperation of the screw rod and the motor, partial paragraphs are in contact with the ejector block when the worm shaft is used for deburring, the worm part of the worm shaft is not in the middle section, and therefore the worm part of the worm shaft is in contact with the ejector block, so that no matter how the grinding wheel polishing assembly is adjusted, the grinding wheel polishing assembly cannot be in contact with the worm part of the worm shaft and perform deburring treatment on the worm part, time and energy are spent for each time of position adjustment before feeding of the worm shaft, the efficiency of the whole deburring work is reduced, the attention of operators is not concentrated due to long-term repeated work, incorrect position adjustment of the worm shaft is easy to occur, and the part of deburring work is output to the outside of equipment. Disclosure of Invention In view of the above problems, there is provided a high-precision worm shaft deburring machine which is easy to adjust, wherein the position of the worm shaft before entering the feeding belt is detected by a detection plate, and the position of the worm shaft with incorrect position is adjusted by a movable frame and a first U-shaped frame. In order to solve the prior art, the high-precision worm shaft deburring machine easy to adjust is provided, which comprises a frame, the material loading subassembly, the pay-off area, spacing seat and sand wheel polishing subassembly, the material loading subassembly includes the fixed plate, the movable frame, first U type frame and pick-up plate, the fixed plate is fixed to be set up in the one end of frame, sliding arrangement has the push pedal on the fixed plate, the slip direction of push pedal is parallel with the transportation direction of pay-off area, push pedal and the output fixed connection of cylinder, the movable frame sets up the one end that is close to sand wheel polishing subassembly on the fixed plate, the worm shaft of putting into on the fixed plate can pass the movable frame under the promotion of push pedal, the axis level of the worm shaft of passing the movable frame is perpendicular with the transportation direction of pay-off area, first U type frame comprises a diaphragm and two longitudinal strips, the diaphragm and the inside top surface swivelling joint of movable frame of first U type frame, the two longitudinal strips of first U type frame point to the bottom surface of movable frame, the output fixed connection of servo motor, the pick-up plate slides and sets up between two longitudinal strips of first U type frame, the worm shaft and the worm shaft of the slip direction of first U type frame and the worm shaft can pass through the worm shaft
