Description

Technical Field

[0001] The utility model relates to a mechanical processing device, in particular to a multi-bevel milling processing device for shaft parts. Background Art

[0002] In the manufacturing of engineering machinery, the end faces of some shaft parts need to be processed in multiple places. The existing clamping of such end faces with multiple bevels is clamped on a horizontal milling machine with a dividing head. One piece is clamped at a time, and the dividing head needs to be rotated manually. Moreover, one workpiece needs to be clamped twice, which makes the processing operation very inconvenient. The disadvantages of this processing using a horizontal milling machine are: the dividing head is set with the required angle of the process, and the shaft to be processed is installed in the three-jaw chuck of the dividing head. After the milling machine processes one position, the dividing head is manually rotated 180 degrees to process the other side. There are four positions on a shaft that need to be processed, which requires clamping twice and the dividing head is rotated twice. The processing operation is very troublesome, with many steps, high labor intensity and low work efficiency. Utility Model Content

[0003] The utility model aims to solve the problems existing in the prior art and provide a multi-bevel milling device for a shaft. The multi-bevel milling device for a shaft has simple processing operation, high working efficiency and strong practicality.

[0004] The technical solution of the multi-bevel milling processing device of the shaft of the utility model includes a clamping table and a clamping device. The clamping table is an inclined clamping table, and the inclination of the inclined clamping table corresponds to the inclination of the corresponding processing inclined surface of the workpiece. The clamping device includes a plurality of V-groove pads corresponding to the corresponding workpieces and arranged on the inclined clamping table, and a clamping body arranged between the inclined clamping table and the corresponding workpiece through a corresponding fastening device. The inclined clamping table is provided with a plurality of adaptive limit devices corresponding to one end of the corresponding workpiece.

[0005] The self-adaptive limiting device comprises a limiting guide seat fixedly arranged on the inclined clamping platform, a limiting block connected to the guide cavity of the limiting guide seat, and a spring connected between the limiting block and the limiting guide seat.

[0006] The fastening device of the clamping device comprises a fastening column and a fastening nut fixedly connected between the inclined clamping platform and the clamping body.

[0007] The clamping body is a pressure plate.

[0008] Compared with the prior art, the multi-bevel milling processing device for shafts of the utility model has the following beneficial effects: 1. There is no need to tilt the dividing head to the process angle during processing. By using V-groove pads and positioning blocks, the shaft to be processed is quickly clamped and positioned, thereby avoiding the need for workers to repeatedly shake the dividing head angle. The workpiece can be rotated 180 degrees by hand, and the processed notch can be directly aligned with the limit block of the processing device for processing, thereby shortening the workpiece clamping time, improving productivity, and reducing the labor intensity of workers; 2. Since the processing device has its own slope angle, workers do not need to calibrate the angle of the dividing head, thereby ensuring processing accuracy, reducing processing errors caused by human factors, and improving product processing quality.

DETAILED DESCRIPTION

[0010] In order to further understand the technical solution of the present invention, the technical solution of the present invention is now clearly and completely described through embodiments in combination with the accompanying drawings.

[0011] like Figure 1-3 The multi-bevel milling device for a shaft of the utility model comprises an inclined clamping table 1, clamping devices respectively arranged on the inclined clamping table 1, and an adaptive limit device for a workpiece. The workpiece in the utility model is a shaft 12.

[0012] In this example, the inclined clamping table 1 includes an angle frame and an inclined table top 11 fixedly connected to the angle frame in an inclined shape. The inclination of the inclined table top 11 of the inclined clamping table corresponds to the inclination of the corresponding processing inclined surface of the workpiece.

[0013] The clamping device includes two V-groove pads 2 fixedly arranged in the middle of the inclined table 11 of the inclined clamping table 1, a pressing plate 4 corresponding to the two V-groove pads 2, a fastening column 3 located between the two V-groove pads 2 and fixedly connected to the inclined table 11 of the inclined clamping table, and a corresponding fastening nut 6. The two V-groove pads 2 are arranged in parallel. The length of the fastening column 3 is greater than the diameter of the corresponding workpiece.

[0014] An adaptive limiting device corresponding to the two V-groove pads 2 and the two corresponding workpieces is provided at the upper end of the inclined table 11 of the inclined clamping table. The adaptive limiting device includes a limiting guide seat 8 fixedly arranged on the inclined table 11 of the inclined clamping table, a limiting block 9, and a corresponding spring 7. The limiting guide seat 8 is provided with a guide cavity 10, one end of the limiting block 9 is connected to the guide cavity of the limiting guide seat 8, and the spring 7 is located between the guide cavity connected to one end of the limiting block 9 and the limiting guide seat, and the free end of the limiting block 9 can correspond to one end of the workpiece.

[0015] During operation, the multi-bevel milling device of the shaft is bolted onto the workbench of the vertical machining center machine tool, the two shafts 2 to be processed are placed on the V-groove pads, the pressure plate 4 is used to cover the upper part of the two shafts 2 on the fastening column, the open washer 5 is covered on the upper end of the fastening column, and then the fastening nut 6 is connected to the upper threaded part of the fastening column and tightened to press the shaft 12; after the upper end grooves of the two shafts are milled during processing, the pressure plate 4 is released, and the shaft 2 is manually rotated 180 degrees, and the spring 7 in the limit guide seat 8 pops out the limit block 9, and the limit block supports the position in the milled groove of the shaft, and the processing is continued after being pressed with the pressure plate; after processing one end, the pressure plate is released to turn the two shafts around and repeat the above process.

[0016] The V-shaped block precision of the utility model can ensure that two shafts are processed at the same height. When the adaptive limit device is not processed, the shaft is placed on the inclined table 11, and the limit block 9 is compressed by its spring, which does not affect the initial processing. After processing one place, the shaft is rotated, and the spring pushes out the limit block to clamp the processed groove for rapid positioning.
