Self-feeding guiding anti-breaking thread tapping device

Abstract

The patent technology belongs to the field of machining tool design, and specifically relates to a self-feeding guide breakage-preventing tapping device, which is suitable for all tapping machines. During tapping, the machine does not need to provide feeding, but only provides a rotating action, the feeding speed is controlled through the rotating speed, the spindle rotation drives the tapping device to rotate, the tap rotation can tap threads on the workpiece, the threads can drive the tap to advance along the increased guide groove and into the workpiece, and tapping is completed. The tap only needs to be reversed by the spindle to retreat along the guide groove. The safety pin shaft will break before the tap, which can protect the tap from breaking.

Description

Technical Field

[0001] This application relates to the field of machining tool design, specifically a self-feeding guided anti-breakage tapping device suitable for all tapping machine tools. Background Technology

[0002] In the machinery manufacturing industry, tap breakage is a common occurrence in machine tool tapping, posing a significant challenge for machine tool operators. Once a tap breaks inside the workpiece, it requires manual removal or electrolytic corrosion, impacting production efficiency and potentially leading to workpiece scrap. Currently, anti-tap breakage devices on the market are relatively expensive. Utility Model Content

[0003] To overcome the above problems, this application proposes a new type of tap protection device that is suitable for all tapping machine tools.

[0004] According to one aspect of this application, a self-feeding guided anti-breakage tapping device is provided, comprising a Morse pin 1, a safety pin 2, a safety pin nut 3, a guide rod 4, and a tap 5;

[0005] The Mo-type sleeve 1 is machined with symmetrical long grooves on both sides, which serve as guide grooves.

[0006] The guide rod 4 has different diameters at both ends, with the larger diameter end having an inner square opening.

[0007] One end of the tap is provided with a square head;

[0008] The smaller diameter end of the guide rod 4 is inserted into the inner hole of the Mo-type sleeve 1, and the smaller diameter end of the guide rod 4 slides within the inner hole of the Mo-type sleeve 1.

[0009] The safety pin 2 passes through the long groove of the Morse pin sleeve 1 and the small through hole of the guide rod 4, and is fixed at both ends by two safety pin nuts 3, thereby constraining the circumferential rotation of the guide rod 4.

[0010] The effective stroke is 89mm. The effective stroke can be varied by changing the length of the long slot of the 1-Mo type sleeve according to the needs of the product.

[0011] The advantages of this application are:

[0012] During tapping, the machine tool does not need to provide feed, only rotational motion. The feed rate is controlled by the rotational speed. The spindle rotation drives the tapper to rotate, and the tap's rotation creates threads on the workpiece. The threads then propel the tap along an added guide groove, pulling it into the workpiece to complete the tapping. Tap retraction is achieved simply by reversing the spindle, causing the tap to retract along the guide groove. A safety pin mechanism prevents the tap from breaking. Attached Figure Description

[0015] The components include: 1. Mo-type bushing, 2. Safety pin, 3. Safety pin nut, 4. Guide rod, and 5. Tap. Detailed Implementation

[0016] The present application is described in detail below with reference to the embodiments, but the present application is not limited to these embodiments.

[0017] Example 1

[0018] An autonomous feed-guided anti-breakage tapping device includes a Morse pin sleeve 1, a safety pin 2, a safety pin nut 3, a guide rod 4, and a tap 5;

[0019] The Mo-type sleeve 1 is machined with symmetrical long grooves on both sides, which serve as guide grooves.

[0020] The guide rod 4 has different diameters at both ends, with the larger diameter end having an inner square opening.

[0021] One end of the tap is provided with a square head;

[0022] The smaller diameter end of the guide rod 4 is inserted into the inner hole of the Mo-type sleeve 1, and the smaller diameter end of the guide rod 4 slides within the inner hole of the Mo-type sleeve 1.

[0023] The safety pin 2 passes through the long groove of the Morse pin sleeve 1 and the small through hole of the guide rod 4, and is fixed at both ends by two safety pin nuts 3, thereby constraining the circumferential rotation of the guide rod 4.

[0024] The effective stroke is 89mm. The effective stroke can be varied by changing the length of the long slot of the 1-Mo type sleeve according to the needs of the product.
