[0024] Figure 1 It is a schematic diagram of the side structure of a workpiece provided in the prior art. Figure 2 It is a front cross-sectional schematic diagram of a workpiece provided in the prior art, such as Figure 1 、 Figure 2 As shown, a certain type of workpiece has a roughly cylindrical shape, and the diameter of its two circular end faces is φ10mm. The workpiece is provided with a side groove 101, the width of the side groove is 8mm, and the eccentric part of the side groove needs to be processed with an M3 thread, that is, the following hole 102 to be processed.

[0025] The current processing technology requires a fitter to clamp and align the thread bottom hole with an alignment pin for tapping. Due to the small size of the parts, clamping and alignment are difficult, and the tapping efficiency is low, which seriously affects the overall processing efficiency and quality of the workshop.

[0026] To solve this problem, the present invention provides an internal thread tapping device. Figure 3 Schematic diagram of the structure of the internal thread tapping device provided by the embodiment of the present utility model. Figure 3 As shown, the device includes: a processing table 6, a positioning groove 1 is provided on the bearing surface of the processing table 6, and the positioning groove 1 is used to accommodate the workpiece to be processed; a positioning boss 2 is provided at the bottom of the positioning groove 1, and the positioning boss 2 is used to clamp the side groove 101 of the workpiece to be processed; a tool drop hole 4 is provided on the positioning boss 2.

[0027] like Figure 3 As shown, the processing table 6 is roughly a rectangular parallelepiped, and a positioning groove 1 is formed on the top end surface thereof. The positioning groove 1 is used to accommodate the workpiece to be processed. When the workpiece to be processed is placed, one side of the workpiece with the side groove facing the bottom of the positioning groove 1 can be installed into the positioning groove 1.

[0028] A positioning boss 2 is provided in the positioning groove 1. Figure 3 、 Figure 4 As shown, the two side walls of the positioning boss 2 are respectively at a certain distance from the side walls of the positioning groove 1 on the corresponding side. In this way, a side groove of the workpiece to be processed can be installed on the positioning boss 2, and the two side edges of the side groove are arranged in the space formed between the positioning boss 2 and the side walls of the positioning groove 1.

[0029] like Figure 4 、 Figure 5 As shown, a tool drop hole 4 is provided on the positioning boss 2. When the workpiece to be processed is mounted on the positioning boss 2, the position of the hole to be processed of the workpiece to be processed can be aligned with the tool drop hole 4, and the tap can be operated to complete the processing of the internal threaded hole of the workpiece to be processed.

[0030] As an optional embodiment, a positioning hole 5 is provided on the positioning boss 2, and the distance between the center of the positioning hole 5 and the center of the tool drop hole 4 is set according to the eccentric distance of the to-be-machined hole 102 of the to-be-machined workpiece.

Preferably, the positioning hole 5 is located in the middle position of the positioning boss 2. The distance between the center of the positioning hole 5 and the center of the tool hole 4 is set according to the eccentric distance of the processing hole of the workpiece to be processed. That is, when the workpiece to be processed is mounted on the positioning boss 2, one end thereof is against the positioning hole 5. At this time, the center of the hole to be punched in the workpiece to be processed coincides with the center of the tool hole 4. At this time, the position of the hole to be punched in the workpiece to be processed can be quickly positioned without manual positioning. At this time, the tap is operated to punch a hole at this position, thereby obtaining a completed workpiece.

[0032] As an optional embodiment, two tool drop holes 4 are provided on the positioning boss 2 , and the two tool drop holes 4 are symmetrically arranged with the central axis of the positioning hole 5 as the axis.

[0036] As an optional embodiment, the diameter of the tool drop hole 4 is larger than the diameter of the hole to be machined.

[0037] The diameter of the tool drop hole 4 is larger than the diameter of the hole to be machined, which can ensure that the operating space is increased when machining the internal thread and ensure that the internal thread hole can be smoothly penetrated.

[0038] In a specific embodiment, the diameter of the hole to be machined is 0.5 mm, and the diameter of the tool drop hole 4 should be greater than 0.5 mm.

[0039] As an optional embodiment, the width of the positioning groove 1 is consistent with the thickness of the workpiece to be processed.

[0040] The width of the positioning groove 1 is consistent with the thickness of the space to be processed, so as to ensure that the workpiece to be processed is supported by the side walls on both sides when it is placed in the positioning groove 1, and will not cause the workpiece to be processed to move left or right.

[0041] As an optional embodiment, the width of the positioning boss 2 is consistent with the width of the side groove of the workpiece to be processed.

[0042] The width of the positioning boss 2 is consistent with the width of the side groove of the workpiece to be processed, ensuring that the side groove of the workpiece to be processed can be stably clamped on the positioning boss 2.

[0043] As an optional embodiment, the processing table 6 is provided with a plurality of fixing holes, which are provided horizontally and are used to fix the processing table 6 on the workbench.

[0044] The processing table 6 is provided with a plurality of fixing holes, which are opened horizontally. The processing table 6 can be fixed to the workbench through the fixing holes, thereby ensuring the stability of the fixing table during tap processing and avoiding the movement of the processing table 6 due to the force generated during tap processing.

[0045] As an optional embodiment, a detachable positioning pin is provided in the positioning hole 5 .

[0046] A detachable positioning pin is provided in the positioning hole 5 , and the positioning pin can be inserted into the positioning hole 5 to position the workpiece to be processed.

[0047] The process of using this device is as follows:

[0048] 1. Insert the positioning pin into the positioning hole;

[0049] 2. Place the two workpieces to be processed into the positioning groove symmetrically in the eccentric direction;

[0050] 3. The tapping machine chuck clamps the M3 tap;

[0051] 4. Complete the internal thread processing of threaded holes in one go;

[0052] 5. Take out the workpiece and proceed with the internal thread tapping of the next batch of workpieces.

[0053] The above technical solution has the following beneficial effects: by setting positioning grooves and positioning bosses corresponding to the workpiece to be processed, and opening tool drop holes at corresponding positions of the positioning bosses, the workpiece can be quickly positioned and clamped, thereby improving processing efficiency and workpiece processing quality.
