In one embodiment, the present embodiments provide a method for processing a cotton picker chassis blank, and in particular, for scoring a cotton picker chassis blank to facilitate processing of the cotton picker chassis blank at a later stage to process a cotton picker chassis. Specifically, the processing method of the cotton picker chassis blank comprises the following steps.
Step 100: the workpiece is leveled on the workbench through the cushion block and the jack.
This step is used to lift the workpiece. Specifically, a plurality of cushion blocks 2 and jacks 3 are prepared on a workbench 1 for standby, so as to cushion according to the structural characteristics of a front axle frame assembly 8 of the cotton picker. Mainly used for cushioning the mechanism with concentrated weight at the bottom of the front axle frame component 8 of the cotton picker. Generally, two or one cushion block 2 are arranged, the height of the cushion block 2 is not changed, the cushion block is generally a metal block, a wood block can be adopted, one or more jacks 3 are generally arranged, two jacks 3 and two cushion blocks 2 with equal heights are generally arranged, so that the height of the jacking end of each jack 3 can be adjusted, and the levelness of a workpiece can be adjusted. The workbench 1 is a marking platform commonly used in the mechanical industry, and the precision grade is not lower than 3 grade. Or a cushion block 2 for heightening can be adopted at a place with a larger plane and a larger contact surface on the workpiece, and a jack 3 is adopted for supporting the place with a smaller contact surface.
Specifically, in order to ensure the leveling, it is preferable here that step 100 includes:
step 110: the workpiece is cushioned on the workbench through the cushion block 2 and the jack 3;
step 120: and measuring the height difference between the supporting surfaces at two sides of one end of the top end of the workpiece, measuring the height difference between the flat plates at two sides of the other end of the top end of the workpiece, judging whether the difference values are all within a set value, if not, adjusting the supporting position of the jack 3, then executing the step again, and if so, executing the next step.
Wherein step 110 is used for cushioning the workpiece, and during the cushioning process, the workpiece is approximately cushioned, i.e. initial cushioning is performed. Leveling is then performed to ensure the workpiece is leveled, via step 120. Wherein the set value is generally smaller than the machining allowance value and generally not larger than one tenth of the machining allowance value of the workpiece, and the smaller the set value is, the better. And when the difference value exceeds the set value, the top end of the jack 3 at the higher side is lowered or the top end of the jack 3 at the lower side is raised. Wherein measuring tool is specific, can adopt and take scale square 6 or equal altitude chi to measure, but equal altitude chi drawback lies in when the stroke is not enough, needs increase cushion 2 and comes the bed hedgehopping, can influence marking efficiency. Based on the height difference, the height difference L of the supporting surfaces at two sides of one end of the top end of the workpiece relative to the workbench 1 can be respectively measured by adopting the right-angle plate 6 with scales1、L1' separately measuring the height difference L between the two side plates at the other end of the top end of the workpiece and the workbench 12、L2', then judges L1And L1' difference between and L2And L2Whether the difference between' is within the set value range. And when the difference exceeds a set value, e.g. L1Greater than L1', then L can be adjusted1Lowering or adjusting L of the jack 3 on one side1' one side jack 3 ascends, e.g. L2Greater than L2', then L can be adjusted2Lowering or adjusting L of the jack 3 on one side2The' one-sided jack 3 ascends.
Step 200: and respectively measuring and determining a vertical central line and a horizontal central line on the flange surfaces at two sides of the workpiece.
This step is aimed at marking the center line for the convenience of later measurement with the center line as reference. According to the appearance of the flange surface 7, the vertical center line x and the transverse center line y of the flange surface on one side, and the vertical center line x 'and the transverse center line y' of the flange surface on the other side are determined by the square plate 6 with the scales so as to determine a reference center line. The flange surface 7 is the side surface on which the flange is milled, and the flange hole is arranged perpendicular to the flange surface 7.
In order to mark the central line better, a reference central connecting line is further determined according to the vertical central lines x and x 'and the horizontal central lines y and y', the reference central connecting line can be connected through a common thin line and is bound on a right-angle backup plate with scales, and the line is enabled to be coincident with the central lines of the two flange plates and has elasticity. It should be noted that the thin lines in the connection manner are only in a common manner, are simple and convenient, and may be connected in other manners, such as laser, and the laser receiver is installed at the center line positions of the two ends, so that the function of accurately positioning the reference center line can be realized. Namely, the vertical central line and the transverse central line can be marked by a line body or a line representation device such as a laser device. Specifically, it is preferable that the vertical center line and the horizontal center line are respectively measured and determined on the flange surfaces on both sides of the workpiece, specifically: measuring a vertical central line and a transverse central line on flange surfaces on two sides of a workpiece by using a measuring tool respectively, and representing the vertical central line and the transverse central line by using a line body or a laser device.
Step 300: and measuring the transverse distance between the corresponding processing reference point and the vertical center line, judging whether the requirement is met, adjusting the position of the vertical center line if the requirement is not met, executing the step again, and executing the next step if the requirement is met.
This step aims to check the machining allowance in the y direction, wherein the y direction is the transverse direction, and the transverse direction refers to the direction perpendicular to the vertical direction in the extending direction of the flange face. The distance between each processing reference point and the vertical center line on the corresponding side is the y-direction distance. According to the vertical center line x, x' and the scaled reference block, the distance Lq (q is 3y, 4y, 5y) can be viewed, where 3y, 4y, 5y refer to the corresponding respective machining positions, and the distance Lq (q is 3y, 4y, 5y) is the distance in the y direction from the center position of each machining position, specifically as shown in the drawing, the general reference points include the shaft sleeve group reference points, such as the first shaft sleeve group 4 and the second shaft sleeve group 5. And then specifically judging that a difference epsilon between the measurement pitch Lq and the design pitch Lq' meets the requirement, and determining that the difference epsilon meets the requirement, wherein the difference epsilon is mainly set according to the actual design requirement, and enough machining allowance is provided under the difference. That is, when the difference epsilon meets the requirement, the determined position of the vertical center line x, x 'is in the allowed range, if the position of the vertical center line x, x' is not in the allowed range, the horizontal center line needs to be properly adjusted until the epsilon value meets the requirement, the specific adjustment mode can be translation, and can also be rotation around the intersection point of the horizontal center line and the horizontal center line, wherein the translation amplitude and the center rotation amplitude are set according to the size of the difference epsilon, and the larger the difference epsilon is, the larger the amplitude of single movement is. It should be noted that the design pitch Lq' is the actual centerline-to-center dimension of the axle set. Specifically, the horizontal distance between the corresponding processing reference point and the vertical center line can be measured by adopting the calibrated reference device 9, the calibrated reference device 9 comprises an L-shaped calibrated reference block 91 with scales and a vertically arranged vertical plate 92, and the lower end of the vertical plate is connected to the horizontal rod part with scales of the L-shaped calibrated reference block in a sliding manner so as to slide along the horizontal rod part with scales. And wherein the upper end of riser can adjust the position from top to bottom to according to adjusting its position, in order to conveniently align.

It should be noted that the execution steps of step 300 and step 400 may be reversed, that is, step 300 may be executed first and then step 400 is executed, or step 400 may be executed first and then step 300 is executed.
This step aims to check the machining allowance in the x direction, wherein the x direction refers to the direction which is consistent with the vertical direction in the extending direction of the flange face. Specifically, Lp (q is 3x, 4x, 5x, 11) can be viewed from the transverse center lines y, y' and the right angle backup plate device with scale, where 3x, 4x, 5x, 11 refer to corresponding respective machining positions, and Lp (q is 3x, 4x, 5x, 11) refers to a distance in the x direction from the center position of each machining position. And then specifically judging that a difference epsilon between the measured pitch Lp and the designed pitch Lp' meets the requirement, and determining that the difference epsilon meets the requirement, wherein the difference epsilon is mainly set according to the actual design requirement, and enough machining allowance is provided under the difference. The scribe line position is within the allowable range, and if not, the lateral centerline position needs to be properly adjusted until the value of e is satisfied. It should be noted that the dimension from the actual center line of Lp' to the center of the axle sleeve group, the right angle backup plate with scale here can be replaced by a contour ruler, only when the stroke is not enough, the cushion block needs to be added to cushion up, and the scribing efficiency is affected. Specifically, can adopt the vertical interval that takes scale square 6 to measure corresponding processing reference point and horizontal central line, take scale square 6 including the right angle backup plate 61 of taking the scale and the clamp plate 62 that the level set up, the one end sliding connection of clamp plate 62 in on the right angle backup plate 61 vertical pole portion to can slide from top to bottom, the other end of clamp plate 62 can the horizontal direction adjusting position.
Step 500: and finishing corresponding scribing on the workpiece.
Namely, in the process of checking the allowance, if the allowance is within the allowance range, a line is directly marked through a marking pen, and marking is finished. In the marking process, the marking device comprises a right-angle backup plate with scales, a reference block with scales and an induction recording ruler, so that the processing efficiency is improved. Specifically, the front end of the platen may be a sharp corner capable of scribing on the surface of the blank so as to be capable of scribing in the vertical direction. Further, for better measurement, it is preferable that the bottom of the pressing plate is provided with a contact sensor to form a contact signal when contacting the surface of the workpiece, so as to form a perception prompt, and a reminder, such as a buzzer or a light alarm, may be further connected.
According to the marking method for the front axle frame assembly of the cotton picker, the workpiece is firstly leveled by the cushion block and the jack, the square type of the cushion is firm and convenient to adjust, and the cushion is conveniently adjusted to be in a leveling state. Furthermore, the center line of the flange surface is determined through the flange surface, then the center line of the flange surface is compared with the reference points, the center line of the flange surface is readjusted according to the difference, and further the reference points and the flange surface have machining allowance, and the adjusting mode is simple and convenient. So as to improve the scribing efficiency and reduce the production cost. In conclusion, the method for processing the cotton picker chassis blank can effectively solve the problem that the scribing operation efficiency is not high in the existing cotton picker chassis blank processing.
Further, before completing the corresponding scribing on the workpiece, the method further includes step 600: and measuring to obtain a central plane between flange surfaces on two sides of the workpiece, and measuring the distance between each corresponding reference point and the central plane.
This step aims to look at the machining allowance in the z direction, wherein the z direction is the parallel direction of the flange surfaces on the two sides. With the tape measure, the center plane is determined, and then Lm (m is 7, 8, 9, 10) is viewed, where 7, 8, 9, 10 refer to the corresponding respective machining positions, and Lm (m is 7, 8, 9, 10) is the distance in the z-direction from the center position of each machining position, as shown in the drawings in particular. And then specifically judging that a difference epsilon between the measurement pitch Lm and the design pitch Lm' meets the requirement, and considering that the difference epsilon meets the requirement, wherein the difference epsilon is mainly set according to the actual design requirement, and enough machining allowance is provided under the difference. It should be noted that Lm is actually measured, and Lm' is a theoretical size. The part can be checked through the measuring tape, and the distance between each corresponding reference point and the central plane can be measured through other modes, such as an induction recording ruler, when the part leans against the two flange plates, the central line can be automatically found out and recorded, and then when the part leans against the side of the shaft sleeve, the corresponding size can be checked.
