[0002] T-type cutter is a cutter installed on the milling machine for milling T-shaped grooves and side grooves of workpieces. T-type cutter is also called T-type milling cutter, semicircular milling cutter, keyway milling cutter, which can perfectly process T-shaped grooves and side grooves. It can maintain cutting performance normally under high temperature. There are several shapes of T-type cutter blades, including positive T-type cutter, T-type cutter with arc, T-type cutter with chamfer, spherical T-type cutter, dovetail T-type and other major shapes.

[0003] The existing pre-milling cutters are all fixedly welded on the pre-milling cutter body. If any milling cutter is damaged, it needs to be replaced as a whole, otherwise the milled surface will be uneven, causing waste, which is not conducive to the use effect of the T-type tool. Utility Model Content

[0004] The purpose of the utility model is to provide a disposable T-shaped cutter to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disposable T-shaped tool, comprising a tool handle, an inner screw hole is opened on the tool handle, an adjusting screw is inserted into the tool handle, a limiting plate is arranged at the end of the adjusting screw, a tool disc is slidably sleeved on the adjusting screw, and a milling blade is arranged on the outer side of the tool disc.

[0006] Preferably, the milling blades are provided in plurality, and the plurality of milling blades are distributed in a circle around the outer side of the cutter disc.

[0007] Preferably, the cutter disc and the milling blade are an integrally formed structure.

[0008] Preferably, the adjusting screw is connected to the inner screw hole by internal and external threads.

[0009] Preferably, a receiving groove is provided on the cutter disc, and the receiving groove is a "T"-shaped circular through-groove structure.

[0010] Preferably, the limiting plate is accommodated in the inner screw hole, and the length of the adjusting screw is smaller than the depth of the inner screw hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model realizes the rapid installation and disassembly of the T-shaped tool through the cooperation between the tool handle, the limit plate and the adjusting screw rod, and can ensure the stability of the assembly. If the part of the milling cutter is damaged, it can be replaced separately to avoid waste, which is beneficial to the use effect of the T-shaped tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of a discardable T-shaped cutter of the utility model.

[0014] Figure 2 The exploded schematic diagram of the T-type tool assembly of the utility model.

[0015] Figure 3 It is a structural schematic diagram of the cutter disc of the utility model.

[0016] In the figure: a tool handle 1; an inner screw hole 11; a tool disc 2; a receiving groove 21; a milling blade 3; a limit plate 4; and an adjusting screw 5. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 3 The utility model provides a technical solution: a disposable T-shaped tool, including a handle 1, an internal screw hole 11 is opened on the handle 1, an adjusting screw 5 is inserted on the handle 1, the adjusting screw 5 and the internal screw hole 11 are connected by internal and external threads, a limiting plate 4 is welded to the end of the adjusting screw 5, a cutter disc 2 is slidably sleeved on the adjusting screw 5, a milling blade 3 is welded on the outer side of the cutter disc 2, and the cutter disc 2 and the milling blade 3 form an integrated structure.

[0019] There are multiple milling blades 3, which are distributed in a circle around the outer side of the cutter disc 2. The cutter disc 2 is provided with a receiving groove 21, which is a "T"-shaped circular through-slot structure. The limiting plate 4 is accommodated in the inner screw hole 11 to reduce the space occupied by the T-shaped tool.

[0020] The length of the adjusting screw 5 is smaller than the depth of the inner screw hole 11 , and the relative distance between the adjusting screw 5 and the inner screw hole 11 can be adjusted according to the thickness of the cutter disc 2 , which is suitable for locking cutter discs 2 of different thicknesses.

[0021] During actual assembly, the cutter disc 2 is sleeved on the adjusting screw 5, and the adjusting screw 5 and the inner screw hole 11 on the tool handle 1 are screwed with each other. The end of the tool handle 1 squeezes the cutter disc 2, so that the limit plate 4 is embedded in the accommodating groove 21 on the cutter disc 2, and then the cutter disc 2 is locked between the tool handle 1 and the limit plate 4, so that the T-shaped tool can be quickly installed and the stability of the assembly can be guaranteed, which is suitable for locking cutter discs 2 of different thicknesses; when disassembling, it is only necessary to reversely screw the adjusting screw 5 and the tool handle 1 to disengage them. If the part of the milling cutter is damaged, it can be replaced separately to avoid waste, which is beneficial to the use effect of the T-shaped tool.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
