Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, and in particular to an auxiliary structure for a benchtop tapping machine. Background Technology

[0002] A benchtop tapping machine is a type of machining equipment mainly used to process various threads, nuts, bolts and other fasteners on metal or non-metal materials. During the processing, the material is first fixed on the worktable, and then the feeding system feeds the material while the rotary system drives the cutting tool to rotate, thereby processing the required threads, nuts, bolts and other fasteners on the material.

[0003] A search revealed Chinese Patent Publication No. CN218745337U, which discloses a rotary table tapping machine. The machine includes a replaceable component on one end of its outer surface, a rotary table assembly at its lower center, and a base on the lower outer surface of the rotary table assembly. The base includes connecting blocks, a groove, a drainage port, a first connecting pipe, a water valve, a water collection tank, moving wheels, and a second connecting pipe. A groove is formed at the upper end of the base, with multiple sets of connecting blocks disposed within it. This rotary table tapping machine, with its base, facilitates the collection of rinsing liquid, preventing it from flowing outside the base. The replaceable component allows for easy replacement of the tap with a brush head after use to clean the base, preventing the liquid mixture from drying and solidifying in the groove.

[0004] While the aforementioned device has certain improvements, it still requires manual lubrication when processing harder plates. Lubrication is performed manually while the machining head rotates to cool the workpiece and head and prevent chipping. Furthermore, lubricating the tapping machine requires the operator to approach or contact the moving parts, increasing the risk of mechanical injury and making manual lubrication cumbersome. Therefore, an auxiliary structure for benchtop tapping machines is proposed to address these issues. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 2-4 This utility model provides an embodiment of an auxiliary structure for a benchtop tapping machine, comprising a housing 1, with a connecting seat 2 on the outer wall of the housing 1. Both the housing 1 and the connecting seat 2 are components of the benchtop tapping machine, and the connecting seat 2 can rotate (this is prior art and will not be explained in detail here). An oiling mechanism 4 is provided at the left end of the housing 1; the oiling mechanism 4 avoids manual oiling. The oiling mechanism 4 includes an oil tank 401, the outer wall of which is inserted into the left end of the housing 1. The oil tank 401 stores lubricating oil and can be disassembled, replaced, or cleaned. A movable column 411 is elastically connected to the inner wall of the oil tank 401 via a connecting spring 410. The bottom end of the movable column 411 is spherical. An oil outlet 412 is provided on the inner side wall of the oil tank 401 to discharge lubricating oil. An oil guide column 407 is fixedly connected to the bottom end of the connecting seat 2. The column 407 is truncated cone in shape and has a machining head at the bottom. A rotating ring 405 is fixedly connected to the outer wall of the oil guide column 407. An inclined groove 406 is opened on the inner wall of the rotating ring 405. The inner wall of the rotating ring 405 can temporarily store the lubricating oil discharged from the oil tank 401. The inclined groove 406 facilitates the discharge of lubricating oil from the inner wall of the rotating ring 405. A compression ring 404 is fixedly connected to the inner wall of the rotating ring 405. The compression ring 404 facilitates the opening of the movable column 411. A positioning block 408 is fixedly connected to the outer wall of the housing 1. A threaded rod 409 is threadedly connected to the inner wall of the positioning block 408. The threaded rod 409 serves as a limit. A movable seat 3 is provided on the outer wall of the housing 1. A scraping mechanism 5 is provided at the top of the movable seat 3. The height of the movable seat 3 can be adjusted. This is prior art and will not be explained in detail here. The scraping mechanism 5 can scrape off the debris on the movable seat 3.

[0035] Reference Figure 2 , Figure 4 and Figure 5One end of the connecting spring 410 is fixedly connected to the top of the movable column 411, and the other end of the connecting spring 410 is fixedly connected to the inner wall of the oil tank 401. The outer wall of the movable column 411 is slidably connected to the inner wall of the oil tank 401. The elasticity of the connecting spring 410 enables the movable column 411 to have a reset closing or opening function. The outer wall of the movable column 411 contacts the outer wall of the oil outlet 412. When the two are in contact, no oil is discharged. The extrusion ring 404 is semi-circular, which is half of the rotating ring 405, and has an inclined surface. The inclined surface is designed to facilitate the flow of lubricating oil discharged from the oil tank 401. The inner wall of the rotating ring 405 is filled with oil, and the top of the extrusion ring 404 contacts the bottom of the movable column 411. The contact between the two causes the movable column 411 to move upward, thereby enabling the oil discharge operation. The top of the oil tank 401 has a screw hole 403, and the bottom of the threaded rod 409 is threaded to the inner wall of the screw hole 403. The threaded connection between the two can fix the oil tank 401, and disassembly only requires rotating the threaded rod 409 in the opposite direction, making the operation simple and convenient. The left end of the oil tank 401 is provided with an oil filling cap 402, which can be opened to allow oil to be injected into the inner wall of the oil tank 401.

[0036] Reference Figure 1 and Figure 5 The scraping mechanism 5 includes a fixed plate 501, the bottom end of which is fixedly connected to the top end of the movable seat 3. The movable seat 3 provides support for the fixed plate 501. A scraper 504 is elastically connected to the inner wall of the fixed plate 501 via a return spring 503. One end of the return spring 503 is fixedly connected to the outer wall of the scraper 504, and the other end is fixedly connected to the inner wall of the fixed plate 501. The elasticity of the return spring 503 enables the scraper 504 to have a reset function, which facilitates subsequent operations. The movement of the scraper 504 can clean and scrape away debris. The bottom end of the scraper 504 is slidably connected to the inner wall of the fixed plate 501, and the sliding between the two serves as a guide. The bottom end of the scraper 504 contacts the top end of the movable seat 3, which facilitates the cleaning operation of the movable seat 3. A handle 502 is fixedly connected to the top end of the scraper 504, which facilitates manual movement of the scraper 504.

[0037] Working principle: When relevant personnel need to perform tapping operations, the workpiece to be processed is first clamped, and then the housing 1 is started to rotate. At this time, the connecting seat 2 will rotate, so that the processing operation can be performed. When the connecting seat 2 is processing, it will drive the rotating ring 405 to rotate. At the same time, the extrusion ring 404 will also rotate. When the inclined surface of the extrusion ring 404 contacts and extrudes the movable column 411, the movable column 411 will move upward. When the movable column 411 moves upward, it will extrude the connecting spring 410, so the movable column 411 will not contact the oil outlet 412. Therefore, the oil outlet 412 will be opened, and the oil inside the oil tank 401 will fall into the inner wall of the rotating ring 405. When the oil volume on the inner wall of the rotating ring 405 reaches a certain level, it will flow through the inclined groove 406 to the guide oil column 407. The guide oil column 407 will then flow the outflowing lubricating oil to the processing head, and then through the processing head, the lubricating oil will flow to the workpiece, thereby achieving the purpose of cooling and avoiding manual oiling, thus saving labor costs.

[0038] When there is a lot of debris on the movable seat 3, the collection box can be placed at the bottom of the movable seat 3. By moving the handle 502, the handle 502 will drive the scraper 504 to move, and the scraper 504 will scrape off all the debris on the movable seat 3, avoiding the need to manually clean the debris with a wiping cloth, thus reducing the safety hazard of debris sticking to people's hands. After scraping, the scraper 504 will reset and retract into the inner wall of the fixed plate 501 for easy use next time.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
