Description

Technical Field

[0001] The utility model relates to the technical field of protection mechanisms, in particular to a protection mechanism for a tapping machine. Background Art

[0002] A tapping machine is a type of mechanical processing equipment that processes internal threads, screws, or threads on the inner side surfaces of various parts with through holes or blind holes of different specifications, such as machine casings, equipment end faces, nuts, flanges, etc. Tapping machines are also called tapping machines, thread tapping machines, thread tapping machines, automatic tapping machines, etc.

[0003] During the tapping process, flying metal debris will be generated, so the tapping machine is usually installed with a protective mechanism to cooperate to provide safety protection, but there are still certain problems: 1) The debris generated by the processing will pile up on the processing table, which is inconvenient to clean frequently and poses certain safety hazards; 2) The top of the existing protective structure is an open structure, and the tapping debris can still fly out through the top opening, and the protective effect is poor; therefore, in view of the above situation, there is an urgent need to develop a protective mechanism for the tapping machine to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of the present utility model is to provide a protection mechanism for a tapping machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a protective mechanism for a tapping machine, comprising a tapping machine and a processing table, wherein the processing table is fixedly mounted on one side of the tapping machine, a protective cabinet is detachably connected to the top edge of the processing table, a side cover is hingedly connected to an opening on one side of the protective cabinet, and a protective cover is slidably connected to the top of the protective cabinet;

[0006] The inner top edge of the processing table is equipped with multiple collection troughs for initially collecting tapping chips, and the inner bottom of the processing table is equipped with a collection tank for collecting tapping chips. The bottom end of the collection trough is equipped with a Y-shaped tube for guiding the tapping chips to the collection tank;

[0007] A through hole is provided in the middle of the protective cover, an outer ring is embedded in the through hole, a magnetic ring is movably provided inside the outer ring, an elastic soft film is installed between the outer ring and the magnetic ring, and a collar is magnetically connected to the top of the magnetic ring.

[0008] Preferably, two through slots are installed at the inner edge of the protective cabinet and penetrate into the interior of the processing table. The through slots are connected to and fixed with the aggregate trough. Specifically, the provided through slots can facilitate the discharge of debris generated during tapping into the aggregate trough.

[0009] Preferably, there are two aggregate troughs, which correspond to the through grooves one by one. The bottom end of the aggregate trough is designed to be inclined toward the collection tank. Specifically, the set aggregate trough can initially collect tapping debris and guide it into the collection tank in conjunction with the Y-shaped tube.

[0010] Preferably, an air pipe joint is provided on the top edge of the collection tank. Specifically, the air pipe joint can be connected to a vacuum device when necessary to create a negative pressure environment in the collection tank, thereby encouraging debris to enter the collection tank and avoid blockage of the aggregate trough and the Y-shaped tube. It should be noted here that a filter element is installed near the air pipe joint in the collection tank to prevent debris from entering the external vacuum equipment.

[0011] Preferably, a plurality of mounting seats are installed on the top edge of the protective cabinet, and a rotatable universal ball is installed on the top of the mounting seat. The highest point of the universal ball is 2 mm higher than the upper surface of the protective cabinet. Specifically, the universal ball can allow the protective cover to slide freely on the upper surface of the protective cabinet to reduce friction. It should be noted here that the size of the protective cover is larger than the size of the top of the protective cabinet. Therefore, when the protective cover is displaced a certain distance, it can still maintain a sealed protection effect on the top opening of the protective cabinet to prevent tapping debris from splashing out.

[0012] Preferably, a processing platform is installed in the middle of the processing table. Specifically, the processing platform is used to place and fix the workpiece to be tapped.

[0013] Compared with the prior art, the present invention provides a protective mechanism for a tapping machine, which has the following beneficial effects:

[0014] 1. The set aggregate trough, Y-shaped tube and collection tank can temporarily store tapping chips to prevent chips from piling up on the processing table, thereby preventing workers from being scratched by metal chips when loading and unloading workpieces, reducing safety hazards to a certain extent and improving chip cleaning efficiency;

[0015] 2. It uses a protective cover and a protective cabinet to fully surround the processing position, which can prevent the tapping debris from splashing out to the greatest extent. The protective cover and the protective cabinet are connected by a universal ball sliding connection, and the protective cover and the tapping machine are driven by a soft film, which makes the protective cover slide smoothly and will not cause a large load on the tapping machine.

[0024] Example:

[0025] See also Figure 1-Figure 4 The utility model provides a technical solution: a protective mechanism for a tapping machine, comprising a tapping machine 10 and a processing table 20, wherein the processing table 20 is fixedly mounted on one side of the tapping machine 10, and a protective cabinet 30 is detachably connected to the top edge of the processing table 20, a side cover 40 is hingedly connected to an opening position on one side of the protective cabinet 30, and a protective cover 50 is slidably connected to the top of the protective cabinet 30;

[0026] The inner top edge of the processing table 20 is equipped with multiple collection troughs 301 for initially collecting tapping chips. The inner bottom of the processing table 20 is equipped with a collection tank 303 for collecting tapping chips. The bottom end of the collection trough 301 is equipped with a Y-shaped tube 302 for guiding the tapping chips to the collection tank 303.

[0027] A through hole is provided in the middle of the protective cover 50, in which an outer ring 501 is embedded. A magnetic ring 503 is movably provided inside the outer ring 501. An elastic soft film 502 is installed between the outer ring 501 and the magnetic ring 503. A sleeve ring 504 is magnetically connected to the top of the magnetic ring 503.

[0028] Preferably, two through grooves 305 that penetrate into the interior of the processing table 20 are installed at the inner edge position of the protective cabinet 30. The through grooves 305 are connected and fixed to the aggregate trough 301. Specifically, the provided through grooves 305 can facilitate the discharge of debris generated during tapping into the aggregate trough 301.

[0029] Preferably, there are two aggregate troughs 301, which correspond one-to-one to the through grooves 305. The bottom end of the aggregate trough 301 is designed to be inclined toward the collection tank 303. Specifically, the set aggregate trough 301 can initially collect tapping debris and introduce it into the collection tank 303 in conjunction with the Y-shaped tube 302.

[0030] Preferably, an air pipe joint 304 is provided on the top edge of the collection tank 303. Specifically, the air pipe joint 304 can be connected to a vacuum device when necessary to create a negative pressure environment in the collection tank 303, thereby prompting debris to enter the collection tank 303 and avoid blockage of the aggregate trough 301 and the Y-shaped tube 302. It should be noted here that a filter element is installed near the air pipe joint 304 in the collection tank 303 to prevent debris from entering the external vacuum device.

[0031] Preferably, a plurality of mounting seats 306 are installed on the top edge of the protective cabinet 30, and a rotatable universal ball 307 is installed on the top of the mounting seat 306. The highest point of the universal ball 307 is 2 mm higher than the upper surface of the protective cabinet 30. Specifically, the universal ball 307 can allow the protective cover 50 to slide freely on the upper surface of the protective cabinet 30, reducing friction. It should be noted that the size of the protective cover 50 is larger than the size of the top of the protective cabinet 30. Therefore, when the protective cover 50 is displaced a certain distance of 0-200 mm, it can still maintain a sealed protection effect on the top opening of the protective cabinet 30 to prevent tapping debris from splashing out.

[0032] Preferably, a processing platform 201 is installed in the middle position of the processing table 20. Specifically, the processing platform 201 is used to place and fix the workpiece to be tapped.

[0033] Working principle: The collar 504 is placed on the outside of the shaft sleeve of the tapping machine 10, and then the magnetic ring 503 is magnetically connected to the collar 504. During processing, the workpiece to be tapped is fixed on the processing platform 201, and then the side cover 40 is closed. The tapping machine 10 drives the cutter head to perform the tapping operation. After the tapping is completed, the side cover 40 is opened to remove the workpiece. The metal debris generated during processing is blocked by the protective cabinet 30 and the protective cover 50 and will remain in the processing chamber. The staff can use a brush to move it into the through grooves 305 on both sides, and then fall into the collecting trough 301 , and is introduced into the collection tank 303 through the Y-shaped tube 302 to realize the collection of metal debris. If necessary, an external vacuum device can be connected through the air pipe joint 304 to generate negative pressure inside the collection tank 303 to realize active collection of debris. It should be noted here that since the soft film 502 is connected to the magnetic ring 503 inside the protective cover 50, for the tapping machine 10 in which the position of part of the cutter head can be horizontally displaced, when the cutter head part moves horizontally, it will cooperate with the soft film 502 to drive the protective cover 50 to slide horizontally on the universal ball 307 to adapt to the tapping position.

[0034] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
