Description

Technical Field

[0001] This utility model belongs to the field of process equipment technology, specifically relating to an adjustable double-tool holder for a CNC slotting machine. Background Technology

[0002] CNC slotting machines are the primary means of machining keys and keyways for various parts, and especially for machining keys and keyways in the housings of electrical connectors. The coaxiality, positional accuracy, and symmetry of keys and keyways in housing parts significantly affect the connection between the connector plug and socket. Previously, machining convex keys in housing parts using CNC slotting machines required multiple clamping operations on one side (positioning, removing excess material) due to the single tool position. Such repeated clamping severely impacted the coaxiality, positional accuracy, symmetry, and consistency of the machining. Multiple repeated clamping operations also significantly limited machining efficiency. Therefore, there is an urgent need to design a suitable dual-tool positioner based on the characteristics of existing CNC slotting machine equipment. Utility Model Content

[0003] Purpose of the utility model: Based on the usage and installation characteristics of CNC slotting machines, a reasonable adjustable double-tool holder is designed and manufactured to achieve one-time clamping and one-time machining of multiple keys and keyways.

[0004] Technical Solution: To achieve the above-mentioned utility model objectives, this utility model designs an adjustable dual-tool holder for a CNC slotting machine, comprising a main tool holder, a secondary tool holder, and an adjusting screw; the main tool holder and the secondary tool holder are respectively provided with tool mounting holes; the main tool holder is also provided with a tool holder mounting handle; the main tool holder and the secondary tool holder are connected at their ends, and the adjusting screw is disposed between the main tool holder and the secondary tool holder for adjusting the coaxiality and position between the main tool holder and the secondary tool holder.

[0005] Furthermore, a dovetail groove is provided at the end where the main cutter holder contacts the secondary cutter holder, and a dovetail platform is provided on the end of the secondary cutter holder, the dovetail platform cooperating with the dovetail groove.

[0006] Furthermore, the dovetail groove is also provided with an adjustment screw hole for installing an adjustment screw. When the adjustment screw is adjusted, it pushes the dovetail table to move, thereby adjusting the coaxiality and position between the main tool holder and the secondary tool holder.

[0007] Furthermore, the end of the adjusting screw is provided with a boss, and the side of the dovetail platform is provided with an adjusting screw hole groove, and the boss is embedded in the adjusting screw hole groove; this method can realize that the dovetail platform moves with the adjusting screw when it moves.

[0008] Furthermore, the adjusting screw is also provided with an adjusting scale.

[0009] Furthermore, the end faces connecting the main tool holder and the secondary tool holder are also provided with threaded holes, which, together with the locking screw, enable the two tool holders to be fixed.

[0010] Furthermore, both the main tool holder and the secondary tool holder are provided with tool position locking holes at their ends, which are used in conjunction with tool position locking screws to fix the tool.

[0011] Furthermore, the tool mounting holes on both the main tool holder and the secondary tool holder are parallel to the tool holder mounting shank and perpendicular to the bottom surface of the tool holder.

[0012] Technical advantages: 1. The tooling adopts a purely mechanical structure, which has a long service life and high stability.

[0013] 2. The tooling has a simple and reasonable structure, is easy to install, and is also adjustable, making it convenient and quick to use.

[0014] 3. The tooling has low requirements for the slotting machine foundation, which greatly improves the current problems of slotting machine equipment such as single function, single tool holder, and low efficiency. Attached Figure Description

Detailed Implementation

[0016] To more clearly illustrate the technical solutions of the embodiments of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings or specific implementation examples. It should be noted that some (but not all) of the disclosed examples are shown in the drawings. In fact, many different examples can be described, and these examples should not be construed as limited to the examples set forth herein. Rather, these examples are described to better demonstrate the positive effects of this utility model, and all aspects not detailed herein are considered to be well-known or conventional techniques in the art.

[0017] See appendix Figure 1 , 2This utility model specifically designs an adjustable double-tool holder for a CNC slotting machine. The specific structure includes a tool position locking screw 1, a locking screw 2, a range adjusting screw 3, a secondary tool holder 4, a main tool holder 5, a main tool holder mounting hole 6, a tool position locking hole 7, a range adjusting hole 8, a range adjusting screw hole 9, a tool holder mounting handle 10, a dovetail groove 11, a secondary tool holder mounting hole 12, a tool position locking hole 13, a range adjusting screw hole groove 14, a dovetail platform 15, and a range adjusting scale 16. The secondary tool holder 4 has a secondary tool position mounting hole 12, a tool position locking hole 13, a range adjusting screw hole groove 14, and a dovetail platform 15 connected to the main tool holder. The range adjusting screw 3 has a range adjusting scale 16 and is connected and installed between the main tool holder 5 and the secondary tool holder 4. The locking screw 3 is used to lock the adjusted main tool holder 4 and secondary tool holder 5, specifically adjusting the movement distance of the secondary tool holder 4 along the Y direction. The main tool mounting hole 6 is parallel to the tool holder mounting handle 10 and perpendicular to the bottom surface of the main tool holder 5; the tool locking hole 13 is perpendicular to the main tool mounting hole 6 and is used to lock the tool; the adjustment hole 8 is perpendicular to the main tool holder 5 and is used to adjust the Y-axis movement distance of the secondary tool holder 4; the adjustment screw hole 9 is coaxial with the adjustment hole 8 and perpendicular to the main tool holder 5; the tool holder mounting handle 10 is perpendicular to the bottom surface of the main tool holder 5; the dovetail groove 11 connecting to the secondary tool holder 4 is perpendicular to the bottom surface of the secondary tool holder 4 and forms a mating connection with the dovetail platform 15 of the secondary tool holder; the secondary tool mounting hole 12 is perpendicular to the bottom surface of the secondary tool holder 4; the adjustment screw hole groove 14 is coaxial with the adjustment hole 8 and perpendicular to the main tool holder 4; the dovetail platform 15 connecting to the main tool holder is perpendicular to the bottom surface of the main tool holder 5 and connects to the dovetail groove of the main tool holder. In specific design, the adjustment scale is 2μm per division.

[0018] When this tool holder is installed on a CNC slotting machine, it is tightened in the tool holder locking groove by the machine tool's own locking screws. After the main and auxiliary tool holders are connected by dovetail grooves, dovetail platforms and adjustment screws, the tools are installed in the tool positions of the main tool holder and auxiliary tool holder respectively, and the tool position locking screws are tightened. The adjustment screw is used to quickly adjust the Y-axis offset of the auxiliary tool holder and the gap between the tool installed in the tool holder. With this tool holder, multiple types of keys and keyways on one side can be machined in one go, and the coaxiality, positional accuracy and consistency are effectively guaranteed, which greatly shortens the machining cycle and reduces the machining cost.
