Description

Technical Field

[0001] This utility model relates to the field of milling cutter mounting technology, specifically a positioning device for milling cutter mounting. Background Technology

[0002] A milling cutter is a rotary cutting tool used for milling operations. Milling cutters are widely used in machining and other fields. They are typically mounted on the spindle of a milling machine, and installation is usually done manually.

[0003] When installing milling cutters, the cutting edge of the milling cutter is quite sharp. Any angular deviation or accidental contact with the cutting edge by the operator may cause serious scratches. This not only reduces installation efficiency but also increases workplace safety risks. Therefore, a positioning device for milling cutter installation is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problem that when installing milling cutters, the cutting edge of the milling cutter is relatively sharp, and any angular deviation or accidental contact with the cutting edge by the operator may lead to serious scratches. This not only reduces installation efficiency but also increases workplace safety risks.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A positioning device for milling cutter installation includes a housing, two threaded rods are rotatably connected inside the housing, the same connecting shaft is fixedly connected to the opposite side of the two threaded rods, a transverse block is threadedly connected to the outer side of each of the two threaded rods, a clamping block is fixedly connected to the top of each of the two transverse blocks, a spring is fixedly connected to the top of the housing, a telescopic rod is fixedly connected to the top of the housing, and the same pressure block is fixedly connected to the top of the spring and the telescopic rod.

[0008] The beneficial effects of this utility model are: by using the pressure block and two clamping blocks, the circular milling cutter can be limited to the top of the outer shell, thereby blocking the cutting edge of the circular milling cutter by the outer shell and preventing accidents caused by improper installation of the cutting edge of the circular milling cutter.

[0009] The positioning device for mounting this milling cutter has the advantage of preventing cuts.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the outer shell is circular, and a circular milling cutter is provided on the top of the pressure block.

[0012] The advantage of adopting the above-mentioned further solution is that, through the circular arrangement, the outer casing can isolate the cutting edge of the circular milling cutter.

[0013] Furthermore, buffer pads are fixedly connected to the outer sides of the pressure block and the two clamping blocks, and the outer sides of the three buffer pads are in contact with the same circular milling cutter.

[0014] The advantage of adopting the above-mentioned further solution is that the buffer pad prevents the circular milling cutter from being damaged during the limiting process.

[0015] Furthermore, an extension shaft is fixedly connected to the right side of the threaded rod on the right side, and a rotating block is fixedly connected to the right side of the extension shaft.

[0016] The advantage of adopting the above-mentioned further solution is that the right-side threaded rod can be rotated by extending the shaft.

[0017] Furthermore, the outer side of the rotating block is knurled, and a support column is fixedly connected to the bottom of the outer shell.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the knurling setting gives the outer side of the rotating block greater friction.

[0019] Furthermore, a rubber handle is fixedly connected to the outside of the support column, and two transverse grooves adapted to the two transverse blocks are opened inside the outer shell.

[0020] The advantage of adopting the above-mentioned further solution is that the two transverse blocks can move through the transverse groove. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the embodiments, by Figure 1-4 The present invention provides a positioning device for mounting a milling cutter. The device includes a housing 1, with two threaded rods 2 rotatably connected inside the housing 1. The two threaded rods 2 are fixedly connected to the same connecting shaft 3 on opposite sides. The outer sides of the two threaded rods 2 are threadedly connected to transverse blocks 4. The top of the two transverse blocks 4 are fixedly connected to clamping blocks 5. The top of the housing 1 is fixedly connected to a spring 6. The top of the housing 1 is fixedly connected to a telescopic rod 7. The top of the spring 6 and the telescopic rod 7 are fixedly connected to the same pressure block 8.

[0028] The outer casing 1 is circular, and the top of the pressure block 8 is provided with a circular milling cutter 9;

[0029] The circular design allows the housing 1 to isolate the cutting edge of the circular milling cutter 9.

[0030] The outer sides of the pressure block 8 and the two clamping blocks 5 are all fixedly connected with buffer pads 10, and the outer sides of the three buffer pads 10 are in contact with the same circular milling cutter 9.

[0031] The buffer pad 10 prevents the circular end mill 9 from being damaged during the limiting process;

[0032] An extension shaft 11 is fixedly connected to the right side of the right threaded rod 2, and a rotating block 12 is fixedly connected to the right side of the extension shaft 11.

[0033] The right-side threaded rod 2 can be rotated via the extension shaft 11;

[0034] The outer side of the rotating block 12 is knurled, and a support column 13 is fixedly connected to the bottom of the outer shell 1;

[0035] The knurling design gives the outer side of the rotating block 12 a greater frictional force.

[0036] A rubber handle 14 is fixedly connected to the outside of the support column 13, and two transverse grooves 15 are provided inside the outer shell 1 to match the two transverse blocks 4.

[0037] The two transverse blocks 4 can move through the transverse groove 15.

[0038] Working principle:

[0039] The circular end mill 9 is placed on top of the pressure block 8 and pressed down, causing the circular end mill 9 to compress the spring 6 through the pressure block 8. Then, the rotating block 12 is rotated, causing the right threaded rod 2 to rotate through the extension shaft 11. The right threaded rod 2 drives the left threaded rod 2 to rotate through the connecting shaft 3, thereby causing the two transverse blocks 4 to move the two clamping blocks 5 to the opposite side. This allows the two clamping blocks 5 to clamp the circular end mill 9, and through the pressure block 8 and the spring 6, the circular end mill 9 is further limited. Then, the circular end mill 9 is installed on the milling machine through the support column 13 and the rubber handle 14. The outer shell 1 isolates the cutting edge of the circular end mill 9 to prevent accidents.
