Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and in particular relates to a guide rod tapping device. Background Art

[0002] In the current machinery manufacturing industry, the role of tapping devices in the guide rod processing process cannot be ignored. It has a significant effect on improving product quality, increasing production efficiency and reducing production costs. However, there are still some problems with the existing tapping devices in my country during the actual processing process, which to a certain extent affect the stability and efficiency of the tapping devices.

[0003] First, the existing tapping device is prone to causing the guide rod to be clamped during the processing process. This is because in the traditional tapping process, manual loading and unloading operations are prone to errors, causing the guide rod to be damaged during the transmission process. This situation not only affects the processing quality of the guide rod, but may also cause wear and tear on the equipment, reducing the service life of the equipment.

[0004] Secondly, the existing tapping device still needs to be improved in terms of automation. At present, most automated equipment directly drops the guide rod into the material frame after completing the automatic loading process. Although this operation method simplifies the manual loading and unloading process, it does not fundamentally solve the efficiency problem of subsequent production operations. Utility Model Content

A plc controller 20 is arranged in the workbench 2, and a control switch 21 is arranged on the outer wall of the workbench 2. The control switch 21, the automatic tapping machine 1, the clamping cylinder 11, the loading cylinder 12, the ejection cylinder 15, and the unloading cylinder 16 are connected in lines.

[0024] In this embodiment, the clamping assembly includes a first connecting block 8, a second connecting block 9, and a displacement block 10. The two ends of the first connecting block 8 are respectively hinged to the second clamping block 6 and the displacement block 10, the two ends of the second connecting block 9 are respectively hinged to the displacement block 10 and the working frame 7, the push rod of the clamping cylinder 11 is hinged to the displacement block 10, and the first clamping block 5, the second clamping block 6, the first connecting block 8, and the second connecting block 9 are arranged in sequence in the working frame 7.

[0025] By adopting the above structure, the displacement block 10 is driven to move by the clamping cylinder 11 to adjust the distance between the first connecting block 8 and the second connecting block 9, so as to move the second clamping block 6 a certain distance away from the first clamping block 5. By adopting this structure, there is no need to adopt a cylinder with more accurate stroke movement. By setting the first connecting block 8 and the second connecting block 9, the distance between the first clamping block 5 and the second clamping block 6 can be effectively controlled to avoid clamping the guide rod 25.

[0026] In this embodiment, the push rod of the unloading cylinder 16 is connected to a plunger head 22 .

[0027] With the above structure, the plunger head 22 can extend out of the bottom hole of the guide rod 25, ensuring that the relative position of the plunger head 22 and the guide rod 25 does not change.

[0028] In this embodiment, a proximity sensor 23 is provided on a side of the positioning track 13 away from the loading track 3, and the proximity sensor 23 is connected to the PLC controller 20 through a wire.

[0029] With the above structure, the proximity sensor 23 plays a role of movement protection. Only when the proximity sensor 23 does not detect the guide rod 25, the feeding cylinder 12 will operate once to prevent multiple guide rods 25 from moving in the direction of the feeding port 18.

[0030] In this embodiment, the unloading cylinder 16 is installed at the bottom of the unloading track 4 through an extension frame 24 .

[0031] The above structure is adopted to prevent the push rod end of the unloading cylinder 16 from not fully extending from the guide rod 25, so that the push rod of the ejection cylinder 15 drives the guide rod 25 to move in the unloading track 4.

[0032] Working principle: connect the vibration plate to the feeding track 3. When the proximity sensor 23 does not detect the guide rod 25 in the positioning track 13, the PLC controller 20 controls the ejection and unloading cylinder 16 to operate. The unloading cylinder 16 drives the plunger head 22 to move up a set distance. After the plunger head 22 moves to the set position, the feeding cylinder 12 moves the guide rod 25 to the feeding port 18 through the picking frame 14. The guide rod 25 falls naturally and is blocked by the plunger head 22. The clamping cylinder 11 drives the displacement block 10 moves forward, the first connecting block 8 and the second connecting block 9 are enlarged, the second clamping block 6 moves toward the first clamping block 5 to clamp the guide rod 25, and the automatic tapping machine 1 taps the guide rod 25. After the tapping is completed, the unloading cylinder 16 drives the plunger head 22 to move down to the initial position. At this time, the guide rod 25 falls on the unloading track 4, and the ejecting cylinder 15 ejects the guide rod 25, so that there is no guide rod 25 at the unloading port 19; the above steps are repeated to realize the assembly line tapping operation.
