Description

Technical Field

[0001] This utility model relates to thread processing technology, and more particularly to a mechanism for processing internal threads in a pen holder. Background Technology

[0002] A tap is a tool for machining internal threads. According to its shape, it can be divided into spiral flute taps, angled taps, straight flute taps, and pipe thread taps, etc. According to its application environment, it can be divided into hand taps and machine taps. According to its specifications, it can be divided into metric taps, US taps, and imperial taps, etc. Taps are the most mainstream machining tool used by operators in manufacturing for tapping. In automated operations, taps need to be connected to a motor to achieve forward and reverse rotation, enabling automated tapping. However, when replacing taps, it is often necessary to remove the entire tap shaft, increasing replacement costs and being very inconvenient. Furthermore, some taps are already installed on equipment, and the equipment's workstation is small, making it difficult to use larger tools for disassembly and assembly. This necessitates the removal of some parts, resulting in longer operation times, lower efficiency, and impacting normal work progress. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes a pen holder internal thread processing mechanism.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A pen holder internal thread machining mechanism includes a rotating shaft with a tapping tool mounted on it. The tapping tool has a receiving hole in its center, and a positioning sleeve is provided within this hole. The positioning sleeve has an insertion hole in its center, and symmetrically arranged notches communicate with the insertion holes.

[0006] The rotating shaft is provided with a mounting end that cooperates with the tapping tool. The mounting end has a mounting hole in the middle that cooperates with the positioning sleeve. The mounting end is provided with a mounting groove and a through groove. A limiting member is provided in the middle of the mounting groove. One end of the limiting member extends through the through groove into the mounting hole and is placed in the notch on the positioning sleeve.

[0007] In this pen holder internal thread processing mechanism of the present invention, the outer wall of the tapping tool is provided with a threaded part, the threaded part is provided with multiple chip removal grooves, and the rotating shaft is provided with a guide groove that cooperates with the chip removal grooves.

[0008] In this pen holder internal thread processing mechanism of the present invention, the rotating shaft is provided with a retaining hole in the middle that mates with the mounting hole, and a spring is provided in the retaining hole. One end of the spring contacts the inner wall of the retaining hole, and the other end contacts the positioning sleeve.

[0009] In this pen holder internal thread processing mechanism of the present invention, the limiting member is composed of an installation section, an elastic section and an inclined section. The installation section is disposed in the installation groove, the elastic section is located in the through groove, and the inclined section is located in the notch.

[0010] In this pen holder internal thread processing mechanism of the present invention, the positioning sleeve is provided with a guide slope that cooperates with the inclined section.

[0011] In this pen holder internal thread processing mechanism of the present invention, the outer wall of the mounting end is provided with symmetrically arranged limiting grooves, and the inner wall of the receiving hole is provided with a limiting block that cooperates with the limiting grooves.

[0012] The pen holder internal thread processing mechanism of this utility model has the following beneficial effects: The mechanism uses an insert-type mating limiting structure to limit the tapping tool, making installation and disassembly convenient in confined spaces. During disassembly, simply inserting a rod longer than the insertion hole pushes the elastic segment on the limiting member, causing it to deform and no longer restrict the position of the tapping tool, thus achieving disassembly. Not only does installation require no tools, but disassembly also only requires a shorter rod, facilitating quick disassembly in confined spaces, improving replacement efficiency, and reducing costs.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1 to 9 As shown, the pen holder internal thread processing mechanism of this utility model has a rotating shaft 2 in the thread processing mechanism 1, and a tapping tool 3 on the rotating shaft 2. The tapping tool 3 can be replaced in time according to the usage time and the presence of damage to the threaded part 4, so that the rotating shaft 2 does not need to be replaced, reducing the difficulty of replacement and the cost, and maximizing the benefits.

[0024] like Figure 1 As shown, the equipment for processing metal pen holders can perform multiple steps. It includes a worktable 5 with a material unloading bin 6 for storing pen holders to be processed. It also includes a pushing mechanism 7, a pen tip cutting and leveling component 8, a boring mechanism 9, a clamping and moving mechanism 10, and a material unloading mechanism 11. The pushing mechanism 7 pushes the pen holders discharged from the material unloading bin 6 into the clamping and moving mechanism 10 for clamping and positioning. The pen tip cutting and leveling component 8 then cuts the pen holder head. The pen holder is then moved between the boring mechanism 9 and the thread processing mechanism 1 via the clamping and moving mechanism 10, allowing for simultaneous boring and thread tapping. Finally, the pen holder is moved to the material unloading mechanism 11 and ejected from the clamping and moving mechanism 10.

[0025] The tapping tool 3 is mounted on the rotating shaft 2. The upper end of the rotating shaft 2 is provided with an outer cover 211. A receiving hole 12 is formed in the middle of the tapping tool 3. A positioning sleeve 13 is provided in the receiving hole 12. An insertion hole 14 is formed in the middle of the positioning sleeve 13. A notch 15 is provided on the positioning sleeve 13, and the notch 15 communicates with the insertion hole 14.

[0026] The tapping tool 3 has a threaded part 4 on its outer wall, and multiple chip removal grooves 16 on the threaded part 4. The rotating shaft 2 has a guide groove 17 that cooperates with the chip removal grooves 16.

[0027] The rotating shaft 2 is provided with a mounting end 18 that cooperates with the tapping tool 3. The mounting end 18 has a mounting hole 19 in the middle that cooperates with the positioning sleeve 13. The mounting end 18 is provided with a mounting groove 20 and a through groove 21. A limiting member 22 is provided in the middle of the mounting groove 20. One end of the limiting member 22 extends through the through groove 21 into the mounting hole 19 and is placed in the notch 15 on the positioning sleeve 13.

[0028] The rotating shaft 2 has a retaining hole 23 in the middle that mates with the mounting hole 19. A spring 24 is installed inside the retaining hole 23. One end of the spring 24 contacts the inner wall of the retaining hole 23, and the other end contacts the positioning sleeve 13. When the tapping tool 3 is installed on the mounting end 18, the spring 24 can apply an external force to the tapping tool 3, causing it to act on the limiting member 22, thereby ensuring that the position of the tapping tool 3 remains unchanged and achieving stable installation.

[0029] The limiting member 22 consists of an installation section 25, an elastic section 26, and an inclined section 27. The installation section 25 is located in the installation groove 20, the elastic section 26 is located in the through groove 21, and the inclined section 27 is located in the notch 15. The installation section 25 is provided with a screw 28, and the installation groove 20 is provided with a threaded hole 29 that mates with the screw 28.

[0030] Meanwhile, the positioning sleeve 13 is provided with a guide slope 30 that cooperates with the inclined section 27. After the elastic section 26 is pushed, the guide slope 30 can cause the elastic section 26 to drive the inclined section 27 to move. The elastic potential energy of the compressed spring 24 pushes the tapping tool 3, so that the guide slope 30 guides the inclined section 27 and makes it disengage from the notch 15.

[0031] Furthermore, symmetrically arranged limiting grooves 31 are provided on the outer wall of the mounting end 18, and limiting blocks 32 that cooperate with the limiting grooves 31 are provided on the inner wall of the receiving hole 12. The positioning and installation of the tapping tool 3 are achieved through the cooperation of the limiting grooves 31 and the limiting blocks 32.

[0032] When installing the tapping tool 3, simply insert the limiting groove 31 and the limiting block 32 together, so that the positioning sleeve 13 pushes the elastic section 26 to deform, then compresses the spring 24, and so that the connection between the inclined section 27 and the elastic section 26 passes the end of the positioning section and reaches the notch 15, thus realizing the position of the tool and completing the installation. No tools are required for quick installation, and installation can be carried out in the confined environment of the equipment, improving the replacement efficiency.

[0033] During disassembly, only a rod with a diameter matching the insertion hole 14 and a length greater than the insertion hole 14 is needed. The rod is then inserted into the insertion hole 14. The rod pushes the elastic segment 26, causing the inclined segment 27 to move. The inclined segment 27 is then held at the guide slope 30. The elastic potential energy of the compressed spring 24 pushes the tapping tool 3, allowing it to disengage from the limiting member 22, thus completing the disassembly.

[0034] The length of its rod can be 1.5 times or 2 times the length of the insertion hole 14.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
