[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides as Figures 1-4The shown rapid positioning support component for the tool head of a numerically controlled machine tool includes a support base 1. A tool head is slidably arranged inside the tool seat support base 1. The cross-section of the support base 1 is of a rectangular structure. The support base 1 is installed on the tool rest of the numerically controlled machine tool. Through the rectangular structure, it is convenient for the support base 1 to be fixed more stably on the tool rest of the numerically controlled machine tool, avoiding the problem of easy slipping of the circular cross-section. The support base 1 and the tool head form the tool of the numerically controlled machine tool.

[0025] Considering that the existing connection stability of the tool head 2 on the tool is not good and the support strength of the tool for the tool head 2 is poor, therefore, the tool head part in the present utility model includes a tool head 2, a connecting rod 3 and a fixing rod 4. The tool head 2, the connecting rod 3 and the fixing rod 4 are fixedly connected and are distributed successively from top to bottom. The diameters of the connecting rod 3 and the fixing rod 4 are the same. A chute 5 is arranged inside the support base 1. The fixing rod 4 is adapted to the chute 5, and the upper surfaces of the fixing rod 4 and the chute 5 are on the same plane. A locking assembly is arranged between the fixing rod 4 and the support base 1. When it is necessary to install the tool head 2, insert the fixing rod 4 into the chute 5, and then fix the fixing rod 4 in the chute 5 through the locking assembly, thereby fixing the tool head 2.

[0026] Furthermore, the locking assembly includes a first jack 8 and a second jack 9. The first jack 8 and the second jack 9 are respectively fixedly arranged on the support base 1 and the fixing rod 4 and respectively penetrate through the two side walls of the support base 1 and the fixing rod 4 at the same time. A screw rod 10 is slidably arranged between the first jack 8 and the second jack 9. One end of the screw rod 10 that extends out of the support base 1 is fixedly provided with a handle. A fastening nut 11 is threadedly connected to the outer circle of the other end of the screw rod 10 that extends out of the support base 1.

[0027] Specifically, after inserting the fixing rod 4 into the inside of the chute 5, insert the threaded end of the screw rod 10 into the first jack 8 and the second jack 9 in sequence, and then tighten the threaded end of the screw rod 10 with the fastening nut 11, thereby fixing the fixing rod 4 inside the chute 5. With such a setting, it is convenient to perform rapid disassembly and replacement processing on the tool head 2. In addition, through the mutual plug-in fit of the fixing rod 4 inserted into the chute 5, more stable support is provided for the tool head 2, and it will not be easily bent and broken during processing, solving the problems that the existing connection stability of the tool head 2 on the tool is not good, the support strength of the tool for the tool head 2 is poor, and in addition, it is not convenient to perform rapid disassembly and replacement processing on the tool head 2.

[0028] In order to quickly align the first jack 8 and the second jack 9, a limiting component is provided between the fixed rod 4 and the sliding groove 5. The limiting component includes four limiting rods 6. The four limiting rods 6 are all fixedly arranged on the inner wall of the sliding groove 5 and are evenly distributed in a ring shape. A limiting groove 7 that engages with the limiting rod 6 is fixedly arranged on the outer side wall of the fixed rod 4. When the fixed rod 4 is inserted into the sliding groove 5, if the positions of the limiting rod 6 and the limiting groove 7 do not align, gently rotate the fixed rod 4 and apply pressure at the same time, then the limiting rod 6 can be easily inserted into the limiting groove 7. After the fixed rod 4 is inserted to the bottom, the first jack 8 and the second jack 9 can overlap in position, realizing the quick positioning and installation of the cutter head 2.

[0029] Considering that the existing cutter head 2 has poor heat dissipation performance, is prone to metal fatigue and damage, and has a short service life. Therefore, a heat dissipation component fixed to the top of the support base 1 is provided on the outer ring of the connecting rod 3. The heat dissipation component includes a heat insulation plate 12. The heat insulation plate 12 is fixedly arranged on the top of the support base 1. In the middle of the top of the heat insulation plate 12, there is a heat dissipation cylinder 13. Through holes for the connecting rod 3 and the fixed rod 4 to pass through are fixedly arranged in the middle of the heat insulation plate 12 and the heat dissipation cylinder 13. The diameter of the through hole is the same as that of the sliding groove 5, and the through hole is adapted to the connecting rod 3. A number of vertically evenly distributed heat dissipation fins 14 are fixedly arranged on the outer ring of the heat dissipation cylinder 13.

[0030] Specifically, the cutter head 2 transfers heat to the connecting rod 3 with good heat conduction performance, and then the heat dissipation cylinder 13 and the heat dissipation fins 14 absorb the heat on the connecting rod 3 and transfer it to the external air, so that the heat generated by the cutter head 2 of the numerical control tool during operation can be quickly dissipated, enabling the numerical control tool to have more functional use effects, and solving the problems that the existing tools do not have other functional effects, have a single use, and poor practicability.

[0031] In addition, through the installation of the heat insulation plate 12, heat is prevented from being transferred to the support base 1, avoiding the problem that the support base 1 will also cause metal fatigue due to long-term heating.

[0032] Furthermore, the screw 10 is located above the limiting rod 6, so that the positions of the screw 10 and the limiting rod 6 will not conflict with each other.

[0033] Further, a floor drain pipe 15 fixedly arranged in the internal structure layer of the support base 1 is communicated with the bottom of the sliding groove 5. A drain pipe 16 is also fixedly arranged inside the support base 1. One end of the drain pipe 16 penetrates through the side wall of the support base 1, and the other end of the drain pipe 16 is communicated with the bottom of the floor drain pipe 15. When there are sundries on the inner wall of the sliding groove 5, such as iron filings, the fixing rod 4 will not be inserted to the bottom, and it will be difficult for the fixing rod 4 to slide into the sliding groove 5 from the inner wall of the sliding groove 5. Therefore, by spraying the inside of the sliding groove 5 with an external water gun, the sundries at the bottom of the sliding groove 5 are flushed out through the floor drain pipe 15 and the drain pipe 16, ensuring the cleanliness inside the sliding groove 5 and facilitating the fixing rod 4 to smoothly fit the inner wall of the sliding groove 5 and slide into and be inserted to the bottom of the sliding groove 5.
