[0002] In the prior art, there are multiple flange holes on the upper end of the part to be processed. Since the flange holes are densely arranged, it is not convenient to perform one-time processing after clamping. It is necessary to clamp twice and then process the flange holes at the clamping position. This requires two processes, so the processing cycle is relatively long, and it wastes manpower and machinery equipment. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a positioning and hole-avoiding press-fitting tool for processing circular holes, comprising a disc, a plurality of pressure plates are arranged on the upper end of the disc, a semicircular groove is opened on the head of the pressure plate, and the semicircular groove corresponds to one of the flange holes of the part to be processed.

[0005] Preferably, the disc is provided with a plurality of flange-processed clearance holes at the upper end at the edge, the plurality of flange-processed clearance holes have the same depth, and the flange-processed clearance holes are concentrically arranged at equal angles.

[0006] Preferably, a threaded hole is opened at the upper end of the disc, a screw is threadedly connected inside the threaded hole, and the screw passes through the pressure plate.

[0007] Preferably, a rectangular groove is provided at the upper end of the disc, and a raised rectangular protrusion is provided at the lower end of the tail of the pressure plate. The rectangular protrusion is slidably connected to the rectangular groove to limit the horizontal and vertical positions of the pressure plate.

[0008] Preferably, a U-shaped groove opening outward is provided at the upper end of the edge of the disc.

[0009] Preferably, the lower end of the disc is fixedly connected to the base, and the lower end of the base is milled with grooves parallel to each other, and there are two U-shaped grooves, which are arranged at both ends of the diameter position of the disc.

[0010] Preferably, the disc and the base are both circular.

[0011] Beneficial effects of the utility model:

[0012] Since the head of the pressure plate has a semicircular groove, all flange holes that need to be processed are not blocked, so the flange holes around the parts to be processed can be processed and formed at one time, which greatly improves the processing efficiency. In addition, the position of the pressure plate is stable, which is convenient for clamping. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. For the purpose of clarity, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not necessary. In addition, for the purpose of simplifying the illustration, some conventional structures and components will be depicted in a simple schematic manner in the illustration.

[0020] like Figure 1-5 As shown, the utility model is a positioning hole-avoiding press-fitting tool for processing circular holes, including a disc 1, a plurality of pressure plates 2 are arranged on the upper end of the disc 1, a semicircular groove 202 is opened on the head of the pressure plate 2, and the semicircular groove 202 corresponds to one of the flange holes of the part to be processed. This structure makes it convenient for the milling machine to process all the flange holes on the upper end of the part to be processed 5 at one time.

[0021] Furthermore, a plurality of flange processing clearance holes 101 are provided at the upper end of the disc 1 at the edge position, and the plurality of flange processing clearance holes 101 have the same depth and are arranged concentrically at equal angles. All flange holes at the upper end of the workpiece 5 to be processed can be processed by one clamping, thereby improving the processing efficiency.

[0022] Furthermore, a threaded hole 104 is provided at the upper end of the disc 1, and a screw 3 is threadedly connected inside the threaded hole 104, and the screw 3 passes through the pressing plate 2. The pressing plate 2 is pressed by tightening the screw 3.

[0023] Furthermore, a rectangular groove 103 is opened at the upper end of the disc 1, and a raised rectangular protrusion 201 is set at the lower end of the tail of the pressure plate 2. The rectangular protrusion 201 is slidably connected with the rectangular groove 103 to limit the horizontal and vertical positions of the pressure plate 2. When in use, the orientation of each pressure plate 2 is fixed, so the position of the semicircular groove 202 at the head of the pressure plate 2 is also stable, which is convenient for the pressure plate 2 to clamp the workpiece 5 to be processed.

[0024] Furthermore, a U-shaped groove 102 with an opening facing outward is provided at the upper edge of the disk 1, and there are two U-shaped grooves 102, which are arranged at both ends of the diameter of the disk 1. The U-shaped groove 102 is used for the dial indicator to assist in straightening and correction during tooling clamping.

[0025] Furthermore, the lower end of the disc 1 is fixedly connected to the base 4, and both the disc 1 and the base 4 are circular. The lower end of the base 4 is milled with grooves 401 parallel to each other, and the base 4 is fixed to the working table of the milling machine through the grooves 401.

[0026] Embodiment: When using the utility model, the groove 401 of the base 4 is clamped by an external fixing device, and the base 4 is fixed to the upper end of the workbench of the milling machine. Then, the part to be processed 5 is placed on the upper end of the disc 1, and then the upper end of the part to be processed 5 is pressed by the pressing plate 2. After tightening the screw 3, the pressing plate 2 can fix the part to be processed 5. Since the head of the pressing plate 2 has a semicircular groove 202, all the flange holes that need to be processed are not blocked, so the flange holes around the part to be processed 5 can be processed and formed at one time, which greatly improves the processing efficiency.

[0027] The above description is only a specific implementation of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and variations.
