Description

Technical Field

[0001] This utility model relates to the field of lathe cutting tools, and in particular to an integrated milling and chamfering tool. Background Technology

[0002] A plunge milling cutter with chamfering is a commonly used machining tool, primarily used for plunge milling of metals, plastics, and other materials. This tool has two parts: a plunger and a chamfering section, enabling both plunge and chamfering to be completed in a single machining operation.

[0003] In existing technologies, when fixing an integrated milling and chamfering cutter, the cutter head is clamped onto a mounting head, which is then screwed onto the lower end of the motor shaft. This fixing is done via threads, and the threaded connection in the same direction can loosen due to the rotation of the motor shaft, making the device unusable for extended periods and requiring periodic checks of the cutter, which is quite cumbersome. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the material becomes loose due to the rotation of the motor shaft, and to propose an integrated milling and chamfering tool.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A single-piece milling and chamfering cutter includes a cutter body with a positioning mechanism on top. The positioning mechanism includes a mounting block, with multiple elastic plates fixedly mounted at the lower end of the mounting block. Positioning plates are fixedly mounted on the inner sides of each elastic plate, and fixing blocks are fixedly mounted on the inner sides of each elastic plate. Multiple positioning grooves are formed on the cutter body, each groove being larger at the top and smaller at the bottom, and these grooves engage with the positioning plates. Multiple fixing grooves are also formed on the cutter body, and these grooves engage with the fixing blocks. A tensioning mechanism is located on top of the cutter body.

[0007] Preferably, the positioning mechanism and the tensioning mechanism are independent of each other.

[0008] Preferably, the tensioning mechanism includes a cylinder, which is threaded to the lower end of a plurality of elastic plates, and a ring is fixedly provided at the upper end of the cylinder. The ring is movably connected to a mounting block, and a tensioning hole is provided inside the cylinder.

[0009] Preferably, the tensioning hole is wider at the top and narrower at the bottom.

[0010] Preferably, a pair of bolts are provided on the outer side of the cylinder, a pair of threaded holes are provided on the cylinder, a pair of threaded grooves are provided on each of the elastic plates, and the bolts are threadedly connected to the threaded holes and threaded grooves.

[0011] Preferably, the lower end of the tool body has two textures.

[0012] Preferably, the mounting block has two pairs of mounting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the bolts are screwed into the threaded holes and threaded grooves to restrict the position of the cylinder and the elastic plate, preventing the cylinder and the elastic plate from shifting due to the rotation of the motor shaft. This allows the device to be used for a long time without the need to check the cutter every once in a while, which is more convenient. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example: This example provides a one-piece plunge milling and chamfering cutter. See [link to example]. Figure 1-7 Specifically, the tool body 1 is provided with a positioning mechanism on the top of the tool body 1. The positioning mechanism includes a mounting block 2. Multiple elastic plates 21 are fixedly provided at the lower end of the mounting block 2. Positioning plates 22 are fixedly provided on the inner side of each elastic plate 21. Fixing blocks 23 are fixedly provided on the inner side of each elastic plate 21. Multiple positioning grooves 24 are provided on the tool body 1. The positioning grooves 24 are larger at the top and smaller at the bottom. The positioning grooves 24 are engaged with the positioning plates 22. Multiple fixing grooves 25 are provided on the tool body 1. The fixing grooves 25 are engaged with the fixing blocks 23. A tensioning mechanism is provided on the top of the tool body 1. The positioning mechanism and the tensioning mechanism are independent of each other.

[0026] The tool body 1 is placed between multiple elastic plates 21 along the positioning plate 22 and the positioning groove 24 until the fixing block 23 is inserted into the fixing groove 25, thus completing the pre-positioning of the tool body 1. The positioning groove 24 is designed to be larger at the top and smaller at the bottom, which facilitates the entry of the fixing block 23 into the positioning groove 24.

[0027] The tensioning mechanism includes a cylinder 3, which is threaded to the lower end of multiple elastic plates 21. A ring 31 is fixedly provided at the upper end of the cylinder 3, and the ring 31 is movably connected to the mounting block 2. A tensioning hole 32 is provided inside the cylinder 3, and the tensioning hole 32 is larger at the top and smaller at the bottom.

[0028] Pull the cylinder 3 down, rotate the cylinder 3 and the elastic plate 21 to engage with the thread, the cylinder 3 moves downward, the tension hole 32 is larger at the top and smaller at the bottom, which will slowly squeeze the elastic plate 21. The tension hole 32 squeezes the elastic plate 21 to fix the tool body 1.

[0029] A pair of bolts 4 are provided on the outer side of the cylinder 3. A pair of threaded holes 41 are provided on the cylinder 3. A pair of threaded grooves 42 are provided on each of the pair of elastic plates 21. The bolts 4 are threadedly connected to the threaded holes 41 and the threaded grooves 42.

[0030] Bolt 4 is screwed into threaded hole 41 and threaded groove 42 to restrict the position of cylinder 3 and elastic plate 21, preventing displacement of cylinder 3 and elastic plate 21 caused by motor shaft rotation. This allows the device to be used for a long time without the need to check the tool every once in a while, which is more convenient.

[0031] The lower end of the blade body 1 has two textures;

[0032] The two textures produce different effects when rotated, enabling the tool body 1 to perform insertion and chamfering operations;

[0033] The mounting block 2 has two pairs of mounting holes 5;

[0034] Mounting hole 5 is used to mount block 2 onto the motor shaft.

[0035] Specifically, the working principle and operation method of this utility model are as follows:

[0036] Mounting hole 5 is used to mount block 2 onto the motor shaft;

[0037] The tool body 1 is placed between multiple elastic plates 21 along the positioning plate 22 and the positioning groove 24 until the fixing block 23 is inserted into the fixing groove 25, thus completing the pre-positioning of the tool body 1. The positioning groove 24 is designed to be larger at the top and smaller at the bottom, which facilitates the entry of the fixing block 23 into the positioning groove 24.

[0038] Pull the cylinder 3 down, rotate the cylinder 3 and the elastic plate 21 to engage with the thread, the cylinder 3 moves downward, the tension hole 32 is larger at the top and smaller at the bottom, which will slowly squeeze the elastic plate 21. The tension hole 32 squeezes the elastic plate 21 to fix the tool body 1.

[0039] Bolt 4 is screwed into threaded hole 41 and threaded groove 42 to restrict the position of cylinder 3 and elastic plate 21, preventing displacement of cylinder 3 and elastic plate 21 caused by motor shaft rotation. This allows the device to be used for a long time without the need to check the tool every once in a while, which is more convenient.

[0040] The two textures produce different effects when rotated, enabling the tool body 1 to perform insertion and chamfering operations.
