Description

Technical Field

[0001] This utility model relates to the field of machining tool technology, specifically a T-slot machining tool with a built-in cooling channel. Background Technology

[0002] T-slot machining tools are specialized cutting tools used to machine "T"-shaped cross-section grooves, or T-slots, onto the surface of workpieces. They are widely used in machinery manufacturing, mold making, tooling and fixtures, and other fields. The function of a T-slot is to fix, slide, or position parts. For example, the T-slot on a machine tool table can be used to fix the workpiece with bolts, and the T-slot in a mold is used to install sliders. T-slot machining tools are the core tools for achieving this special groove shape machining.

[0003] In the prior art, such as the carbide T-slot end mill disclosed in publication number CN220838118U, a T-slot is provided on a part, and an end mill is provided in the T-slot. The end mill includes a shank located outside the T-slot, and a screw barrel extending into the T-slot is provided on the shank. A first tool and a second tool that mate with the T-slot are sleeved on the screw barrel, and a screw extending into the screw barrel is provided at the bottom of the second tool. It can simultaneously machine the opening and bottom of the T-slot from the edge of the part, resulting in high machining efficiency; the first and second protrusions can respectively limit the movement of the first and second tools.

[0004] While existing cutting tools can simultaneously process the opening and bottom of the T-slot from the edge of the part, resulting in high processing efficiency, and the protrusions one and two can limit the cutting tools one and two respectively, it is inconvenient to dissipate heat from the cutting tools during use. When the cutting tools rotate and cut the workpiece, they generate a lot of heat, and the inability to dissipate heat in time will affect the cutting effect on the workpiece. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology has the problem of inconvenience in dissipating heat from the cutting tool during use, and that the tool generates a lot of heat when rotating and cutting the workpiece, the inability to dissipate heat in time will affect the cutting effect on the workpiece.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A T-slot machining tool with a built-in cooling channel includes a fixed tool holder, an adjustable tool holder, a limiting bolt, and a limiting hole. The adjustable tool holder is telescopically connected to the front end of the fixed tool holder. The limiting bolt is installed on the outer surface of the fixed tool holder, and its end is inserted into the limiting hole formed on the adjustable tool holder. The tool also includes: The water inlet pipe is located at the rear end of the fixed tool holder, and the fixed base is located on one side of the fixed tool holder.

[0008] As a further embodiment of this utility model: the water inlet pipe includes a fixed bearing, the fixed bearing is fixed on the outer surface of the water inlet pipe, and a limit plate is fixed at one end of the water inlet pipe.

[0009] As a further embodiment of this utility model: a limit block is fixed at one end of the adjusting handle, and a flow cavity communicating with the interior of the fixed handle is provided inside the adjusting handle.

[0010] As a further improvement of this utility model: the end of the adjusting handle is provided with a fixed blade head, and a buffer cavity is provided inside the fixed blade head.

[0011] As a further improvement of this utility model, the outer surface of the fixed blade is provided with a water spray hole that communicates with the buffer cavity.

[0012] As a further improvement of this utility model: two limiting grooves are provided inside the fixed knife handle, and guide blocks that are fixedly connected to the limiting blocks are slidably connected inside the two limiting grooves.

[0013] As a further improvement of this utility model: the fixing base includes two locking blocks, which are inserted and connected inside the fixing base.

[0014] As a further improvement of this utility model: a cutting blade is fixed on one side of each of the two clamping blocks, and a fixing screw that is threadedly connected to the fixing seat is installed inside the cutting blade.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a fixed bearing set on the inner wall of the fixed tool holder. The cooling water in the fixed tool holder will enter the flow chamber inside the adjusting tool holder through the limiting block and flow into the fixed tool head. Through the buffer chamber, the cooling water will be sprayed out through several water spray holes corresponding to the cutting blade, thereby cooling the cutting blade and effectively reducing the possibility of the tool overheating.

[0016] 2. This utility model loosens the limiting bolt on the fixed tool handle, separating the limiting bolt from the limiting hole on the adjusting tool handle, thus releasing the fixing of the adjusting tool handle. With the cooperation of the limiting groove and the guide block, the adjusting tool handle can be pulled horizontally, thereby adjusting the overall length of the tool. Attached Figure Description

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Example 1: Please refer to Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a T-slot machining tool with a built-in cooling channel, including a fixed tool holder 1, an adjustable tool holder 2, a limiting bolt 3, and a limiting hole 4. The adjustable tool holder 2 is telescopically connected to the front end of the fixed tool holder 1. The limiting bolt 3 is installed on the outer surface of the fixed tool holder 1, and the end of the limiting bolt 3 is inserted into the limiting hole 4 opened on the adjustable tool holder 2. It also includes: The water inlet pipe 5 and the fixing seat 6 are provided. The water inlet pipe 5 is located at the rear end of the fixed tool holder 1, and the fixing seat 6 is located on one side of the fixed tool holder 1.

[0022] Specifically, the water inlet pipe 5 includes a fixed bearing 51, which is fixed on the outer surface of the water inlet pipe 5. One end of the water inlet pipe 5 is fixed with a limit plate 52, and one end of the adjusting handle 2 is fixed with a limit block 53. The interior of the adjusting handle 2 is provided with a flow cavity 54 that communicates with the interior of the fixed handle 1.

[0023] Furthermore, the water inlet pipe 5 provided on the fixed tool holder 1 is connected to an external cooling water source, allowing cooling water to enter the fixed tool holder 1 through the water inlet pipe 5. The fixed bearing 51 provided on the inner wall of the fixed tool holder 1 prevents the water inlet pipe 5 from rotating when the fixed tool holder 1 rotates, ensuring the normal delivery of cooling water. The limiting plate 52 provided on the water inlet pipe 5 can play a limiting role. The cooling water entering the fixed tool holder 1 will pass through the limiting block 53 and enter the flow cavity 54 inside the adjusting tool holder 2.

[0024] Specifically, the end of the adjusting handle 2 is provided with a fixed cutter head 55, the inside of the fixed cutter head 55 is provided with a buffer cavity 56, and the outer surface of the fixed cutter head 55 is provided with a water spray hole 57 that communicates with the buffer cavity 56.

[0025] Furthermore, the cooling water is sprayed out through several water spray holes 57 corresponding to the cutting blade 62 through the buffer chamber 56, thereby cooling the cutting blade 62 and effectively reducing the possibility of the tool overheating.

[0026] In use, the water inlet pipe 5 on the fixed tool holder 1 is connected to an external cooling water source, allowing cooling water to enter the fixed tool holder 1 through the water inlet pipe 5. The fixed bearing 51 on the inner wall of the fixed tool holder 1 prevents the water inlet pipe 5 from rotating when the fixed tool holder 1 rotates, ensuring normal cooling water delivery. The limiting plate 52 on the water inlet pipe 5 can limit the flow of cooling water into the fixed tool holder 1. The cooling water entering the fixed tool holder 1 passes through the limiting block 53 into the flow chamber 54 inside the adjusting tool holder 2, and then flows into the fixed tool head 55. The cooling water is sprayed out through several spray holes 57 corresponding to the cutting blade 62 through the buffer chamber 56, thereby cooling the cutting blade 62 and effectively reducing the risk of the tool overheating, thus improving its practicality.

[0027] In summary, when the T-slot machining tool with built-in cooling channel is in use, the cooling water in the fixed tool holder 1 will enter the flow cavity 54 inside the adjusting tool holder 2 through the fixed bearing 51 set in the inner wall of the fixed tool holder 1, and flow into the fixed tool head 55. Through the buffer cavity 56, the cooling water will be sprayed out through several water spray holes 57 corresponding to the cutting blade 62, thereby cooling the cutting blade 62 and effectively reducing the possibility of the tool overheating.

[0028] Example 2: Please refer to Figures 1-5 This is the second embodiment of the present utility model.

[0029] Specifically, the fixed tool holder 1 has two limiting grooves 58 inside, and the two limiting grooves 58 are slidably connected to guide blocks 59 which are fixedly connected to limiting blocks 53.

[0030] Furthermore, by loosening the limiting bolt 3 on the fixed tool holder 1, the limiting bolt 3 is separated from the limiting hole 4 on the adjusting tool holder 2, thus releasing the fixing of the adjusting tool holder 2. With the cooperation of the limiting groove 58 and the guide block 59, the adjusting tool holder 2 can be pulled horizontally, thereby adjusting the overall length of the tool.

[0031] Specifically, the fixing base 6 includes two locking blocks 61. The two locking blocks 61 are inserted into the interior of the fixing base 6. A cutting blade 62 is fixed on one side of each of the two locking blocks 61. A fixing screw 63 that is threadedly connected to the fixing base 6 is installed inside the cutting blade 62.

[0032] Furthermore, by unscrewing the fixing screw 63 on the cutting blade 62, the fixing screw 63 is separated from the fixing seat 6. With the cooperation of the locking block 61, the cutting blade 62 can be pulled vertically, thereby disassembling and replacing the cutting blade 62.

[0033] In use, by fixing the fixed tool holder 1 to the machine tool output shaft, the machine tool can drive the fixed tool holder 1 to rotate, driving the tool to process the workpiece. Through the several locking blocks 61 set on the fixed seat 6, when the cutting blade 62 is driven to move, a T-slot can be machined on the workpiece. By unscrewing the fixing screw 63 on the cutting blade 62, the fixing screw 63 is separated from the fixed seat 6. With the cooperation of the locking blocks 61, the cutting blade 62 can be pulled vertically, thereby disassembling and replacing the cutting blade 62 for easy use. By loosening the limiting bolt 3 on the fixed tool holder 1, the limiting bolt 3 is separated from the limiting hole 4 on the adjusting tool holder 2, releasing the fixing of the adjusting tool holder 2. With the cooperation of the limiting groove 58 and the guide block 59, the adjusting tool holder 2 can be pulled horizontally, thereby adjusting the overall length of the tool.

[0034] In summary, when using the T-slot machining tool with built-in cooling channel, the cooling water inside the fixed tool holder 1 enters the flow chamber 54 inside the adjusting tool holder 2 through the fixed bearing 51 set on the inner wall of the fixed tool holder 1, and flows into the fixed tool head 55. Through the buffer chamber 56, the cooling water is sprayed out through several water spray holes 57 corresponding to the cutting blade 62, thereby cooling the cutting blade 62 and effectively reducing the possibility of the tool overheating. Furthermore, by loosening the limiting bolt 3 on the fixed tool holder 1, the limiting bolt 3 is separated from the limiting hole 4 on the adjusting tool holder 2, releasing the fixing of the adjusting tool holder 2. With the cooperation of the limiting groove 58 and the guide block 59, the adjusting tool holder 2 can be pulled horizontally, thereby adjusting the overall length of the tool.

[0035] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
