Description
TECHNICAL FIELD
[0001] The present application belongs to the field of mechanical processing, and particularly relates to a device for processing high-interchangeability bracket parts. BACKGROUND
[0002] The bracket part is a kind of part commonly used in mechanical processing, and is usually used for the connection with other functional parts or the support of moving parts and other parts, so that the dimensional accuracy and the geometric tolerance of the part are required to be high. When the processing method is selected, the common three-axis processing machine tool is usually used for processing, and generally multiple steps and multiple clamping are required to complete the processing of one part. However, for some bracket parts with high interchangeability requirements, the conventional processing method will cause the accumulation of multiple errors, resulting in poor consistency of the dimensional accuracy and the geometric tolerance of the batch parts, and the interchangeability requirements of the batch parts cannot be met.
[0003] The accumulation of errors is caused by the following factors: (1) the clamping positioning error caused by the multiple clamping times; (2) the random error caused by the slight differences in the environment, equipment, clamping force and the like during each clamping; and (3) the system error caused by the technical level and the adjustment error of the process system of the operator. The accumulation of the above errors causes the dimensional accuracy and the geometric tolerance of the batch parts to be randomly distributed between the upper and lower deviations during the processing, although the single part is qualified in inspection, but the interchangeability of the batch parts is poor. For parts with high dimensional consistency requirements or used in group assembly, the subsequent use requirements cannot be met. Therefore, a processing method capable of reducing the error of the bracket part is required to improve the dimensional accuracy, consistency and interchangeability of the batch parts.

[0018] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in more detail below by combining with the drawings of the specification, but the utility model is not limited to this.
[0019] The utility model will be described in further detail below by specific example and combining with the drawings.
[0020] As Figure 2 The device for processing high interchangeability support class parts includes rotary body 1, adjustable positioning groove 2, positioning screw 3, pressing plate 4, clamping bolt 5.As Figure 1 The one end of rotary body 1 is cylindrical body, and is coupled with the rotary indexing head of processing equipment, and the other end is cuboid, and is used for the clamping positioning of part, and the height of cuboid is 1mm lower than the height of the high interchangeability support class part.The cylindrical body is integrally formed with cuboid, and the material is quenched steel.Positioning screw 3 is coupled with rotary body 1 through two adjustable positioning grooves 2 on one side of rotary body 1.According to the size of the processed support part, positioning screw 3 can be moved in adjustable positioning groove 2, so that the correct position of the part on the device is found, that is, the center line of the processed part in the direction is coaxial with the rotary center of the device, and is locked after finding.The length of adjustable positioning groove 2 is 10mm.Clamping bolt 5 passes through pressing plate 4 and is coupled with bolt hole 6 on both sides of rotary body 1, and plays the role of pressing the high interchangeability support part.
[0021] The working principle and process of the device for processing high interchangeability support class parts of the utility model are as follows:
[0022] As Figure 3 And Figure 4As shown, the three-jaw chuck of the equipment with rotation machining capability or the dividing head clamps the cylinder at one end of the rotating body 1, the positioning screw 3 is coupled with the rotating body 1 through the two adjustable positioning grooves 2 on one side of the rotating body 1, and is aligned and locked. The bracket part to be machined is attached to the two positioning screws 3, the clamping bolt 5 passes through the pressing plate 4 and is pressed on the machined part, and the two ends are coupled and tightened with the threaded holes 6 on both sides of the rotating body 1, so that the clamping and positioning are completed. Before each batch is used, the two positioning screws 2 are adjusted in the front and back of the positioning groove 3 according to the size of the part, and the position is recorded. The part is machined only once. Then the equipment with rotation machining capability or the dividing head drives the device and the machined part to rotate to the first machining surface (b) for machining, and then the device is driven to rotate to the second machining surface (c) for machining, so as to ensure the consistency and high accuracy of the size required by the drawing. This machining method can eliminate the cumulative error caused by the operator and the process system, and theoretically only produces the repeated positioning error of the machining equipment, which is much lower than the consistency error required by the drawing, and can well meet the machining requirements of the high interchangeability bracket parts.
