In order to solve the technical problem, the utility model provides a following technical scheme:

a notch milling tool comprises a bottom plate and a panel which forms a preset angle with the bottom plate, wherein a panel notch is formed in the top of the panel; the panel is provided with positioning blocks which are positioned at two sides of the panel gap, the bottom of the panel is provided with a nut, and a compression screw is screwed in the nut; the panel is also provided with a pressing plate, and the pressing plate is connected with the panel through a bolt and an adjusting nut.

Wherein, a rib plate is arranged between the panel and the bottom plate.

The number of the rib plates is two, and the two rib plates are symmetrically arranged.

The positioning blocks are symmetrically arranged on two sides of the panel gap.

The inner side wall of the positioning block is matched with the outer diameter of the workpiece to be machined.

Wherein the panel is octagonal, and the panel notch is located in the middle of the top edge of the panel.

The number of the pressing plates is two, and the two pressing plates are symmetrically arranged along the central axis of the panel.

Wherein, the compression screw is arranged opposite to the panel gap.

The utility model discloses an above-mentioned technical scheme's beneficial effect as follows:

according to the scheme, the notch milling tool can be used for processing the notch of the groove ring by adopting a milling method, so that the processing cost is greatly reduced compared with that of linear cutting processing, and the notch milling tool is simple in structure, easy to manufacture and low in production cost.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 5, an embodiment of the present invention provides a notch milling tool, which includes a bottom plate 11 and a panel 13 forming a predetermined angle with the bottom plate 11, wherein a panel notch 131 is formed at the top of the panel 13; the panel 13 is provided with positioning blocks 1, the positioning blocks 1 are positioned on two sides of the panel gap 131, the bottom of the panel 13 is provided with a nut 6, a compression screw 7 is screwed in the nut 6, a workpiece to be processed is placed between the positioning blocks 1 and the nut 6 during processing, and the compression screw 7 and the nut 6 are combined to clamp the workpiece; the panel 13 is further provided with a pressing plate 3 for pressing a workpiece, and the pressing plate 3 is connected with the panel 13 through bolts and adjusting nuts 2.

As shown in fig. 3, a rib 12 is disposed between the face plate 13 and the bottom plate 11 to play a role of reinforcing support. The bottom plate 11, the rib plate 12 and the face plate 13 are connected by assembly welding, and an included angle alpha between the face plate 13 and the bottom plate 11 is consistent with an included angle beta between the notch of the groove ring and the end face.

As shown in fig. 5, the number of the rib plates 12 is two, and the two rib plates 12 are symmetrically arranged.

As shown in fig. 4, the number of the positioning blocks 1 is two, and the two positioning blocks 1 are symmetrically disposed on two sides of the panel notch 131.

In this embodiment, the inner side wall of the positioning block 1 is adapted to the outer diameter of the workpiece to be machined, so as to play a role in positioning when the workpiece to be machined is placed.

As shown in fig. 4, the panel 13 is octagonal, and the panel notch 131 is located at the middle of the top edge of the panel 13.

Specifically, the number of the pressing plates 3 is two, and the two pressing plates 3 are symmetrically arranged along the central axis of the panel 13 and are respectively arranged at the upper left and the upper right.

As shown in fig. 4, the compression screw 7 is disposed opposite to the panel notch 131, and the workpiece to be processed is clamped and fixed by the combined action of the compression screw 7 and the positioning block 1.

In this embodiment, each of the pressing plates 3 is connected to the panel 13 through a bolt, and the adjusting nut 2 is located outside the workpiece to be processed, so that the pressing plate 3 is rotated to place the workpiece to be processed when the tool is used.

The utility model provides a mill use of breach frock as follows:
