Description

Technical Field

[0001] The present invention relates to the technical field of tapping machines, and specifically relates to a numerically controlled tapping machine for the production of steel bar sleeves. Background Art

[0002] Numerically controlled tapping machines are applicable to many mechanical manufacturing industries, machine tools, die machines, plastic machines, printing machines and other industries. Numerically controlled tapping machines have the advantages of being portable, flexible, efficient and irreplaceable by some other equipment during use. After the numerically controlled tapping machine is powered on, the power controller is turned on, the tapping speed is set, the forward rotation is pressed, and the servo motor converts the voltage and signal into torque and speed output for tapping operations. After tapping to a certain height, the reverse rotation is pressed to retract the thread. The tapping accuracy is high, and the height can be adjusted, and tapping can be performed at any position within the operating radius.

[0003] At present, numerically controlled tapping machines for the production of steel bar sleeves on the market generally use a clamping method by cylinders or electric telescopic rods to fix the steel bar sleeves, and the cost is relatively high. For example, the patent with the Chinese utility model publication number CN221910132U discloses a numerically controlled tapping machine for the production of steel bar sleeves. Through the setting of structures such as a connecting seat and a clamping assembly, during operation, the workpiece is placed on the connecting seat, and the tapping machine body is driven to descend by a cylinder. Since a gear cylinder is fixedly connected to the bottom of the tapping machine body, the gear cylinder meshes with the spur gear. When the tapping machine body descends, it drives the gear cylinder to move downward, and then drives the synchronous shaft and the circular gear to rotate, driving the thread ring to rotate. The four sliding clamping blocks move synchronously through the synchronous belt, clamp and fix the workpiece, realizing the rapid positioning of the workpiece. However, in actual use, it requires more transmission structures, and during the tapping process, a large amount of debris will be generated. If the debris comes into contact with the transmission structures, it will seriously affect the normal use of the equipment, bringing inconvenience to the fixing work of the steel bar sleeves, and having certain limitations.

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0030] In this application, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] In addition, in this application, descriptions such as "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0032] After the numerical control tapping machine for producing steel bar sleeves fixes the steel bar sleeves by means of clamping with an air cylinder or an electric telescopic rod, the power supply of the tapping machine is turned on, the power controller is turned on, the tapping speed is set, the forward rotation is pressed, and the servo motor converts the voltage and signal into torque and rotational speed output for tapping operations. After tapping to a certain height, press the reverse rotation to retract the thread.

[0033] In the related art, through the setting of structures such as a connecting seat and a clamping assembly, during operation, the workpiece is placed on the connecting seat, and the tapping body is driven by an air cylinder to descend. Since a gear cylinder is fixedly connected to the bottom of the tapping body, the gear cylinder meshes with a spur gear. When the tapping body descends, it drives the gear cylinder to move downward, thereby driving the synchronous shaft and the circular gear to rotate, driving the thread ring to rotate, and the four sliding clamping blocks move synchronously through a synchronous belt to clamp and fix the workpiece, achieving the rapid positioning of the workpiece. However, in actual use, it requires more transmission structures, and during the tapping process, a large amount of debris will be generated. If the debris contacts the transmission structures, it will seriously affect the normal use of the equipment, bringing inconvenience to the fixing work of the steel bar sleeves and having certain limitations.

[0034] To solve the problems in the related art to a certain extent, the embodiment of this application provides a numerical control tapping machine for producing steel bar sleeves. When in use, only

[0035] , which is more convenient and fast, improving the convenience of the device.

[0036] The following describes this application with reference to the accompanying drawings and specific embodiments:

[0037] Combined with Figures 1 - 5 In an embodiment of the present application, a numerically controlled tapping machine for producing steel bar sleeves is provided, including: a tapping machine body 10, on which an adjusting mechanism 20 is provided. The adjusting mechanism 20 is symmetrically installed with mounting plates 21. The adjusting mechanism 20 is used to adjust the position of the mounting plates 21. A connecting plate 22 is slidably connected inside one side of the mounting plate 21. One end of the connecting plate 22 is fixedly connected with a clamping plate 23. A first limiting plate 24 is slidably connected inside the mounting plate 21. One end of the first limiting plate 24 is rotatably connected with the connecting plate 22 through a connecting seat 25. A set screw 26 is threadedly connected to the mounting plate 21. A hole 27 is formed in the connecting plate 22. One end of the set screw 26 is inserted into the hole 27 to fix the connecting plate 22.

[0038] During processing, after installing the tapping machine body 10 at a designated position, place the steel bar sleeve to be processed between the two clamping plates 23. Then, through the adjusting mechanism 20, adjust the position of the mounting plate 21 so that the mounting plate 21 and the connecting plate 22 drive the two clamping plates 23 to slide towards the opposite surfaces. Subsequently, after the two clamping plates 23 clamp the steel bar sleeve, turn on the power supply of the tapping machine, open the power controller, set the tapping speed, press the forward rotation button, and the servo motor will convert the voltage and signal into torque and rotational speed output for tapping operation. After tapping to a certain height, press the reverse rotation button to retract the thread to complete the tapping operation (the tapping operation belongs to the prior art, so it will not be elaborated too much). Until the tapping is completed, operate the adjusting mechanism 20 to adjust the position of the mounting plate 21 again. After the clamping plate 23 is separated from the steel bar sleeve, directly take out the steel bar sleeve from between the two clamping plates 23 to complete a cycle. Then repeat the above steps to realize the tapping processing of multiple steel bar sleeves. Finally, rotate the set screw 26 so that one end of the set screw 26 slides out of the hole 27, cancel the fixation of the connecting plate 22, pull the clamping plate 23 outwards, and when the clamping plate 23 drives the connecting plate 22 and the first limiting plate 24 to slide out of the mounting plate 21, expose the connecting seat 25. Then rotate the clamping plate 23 so that the clamping plate 23 drives the connecting plate 22 to rotate. After the clamping plate 23 and the connecting plate 22 rotate 90 degrees, they are separated from the tapping machine body 10, which is convenient for cleaning the debris remaining on the tapping machine body 10.

[0039] In some embodiments, holes 27 are provided in both the connecting plate 22 and the first limiting plate 24. When the clamping plate 23 is pulled to slide the first limiting plate 24 out of the mounting plate 21, after the hole 27 on the first limiting plate 24 is aligned with the set bolt 26, the set bolt 26 is rotated to insert the set bolt 26 into the hole 27 to fix the first limiting plate 24. Subsequently, after the connecting plate 22 is rotated by more than ninety degrees, the angle between the top of the first limiting plate 24 and the side of the connecting plate 22 is an acute angle, and then the clamping plate 23 can be directly released, facilitating subsequent cleaning operations.

[0040] In some embodiments, the width of the connecting plate 22 is less than the width of the first limiting plate 24, and a T-shaped sliding groove is provided inside the mounting plate 21 to prevent the first limiting plate 24 from detaching from the mounting plate 21.

[0041] In some embodiments, the adjusting mechanism 20 is composed of a box body and a bidirectional threaded rod. The box body is fixedly connected to the tapping machine body 10, the bidirectional threaded rod is rotatably connected inside the box body, and both mounting plates 21 are threadedly connected to the bidirectional threaded rod.

[0042] During adjustment, the bidirectional threaded rod is rotated, and then through the threaded connection between the mounting plate 21 and the bidirectional threaded rod, the left and right positions of the mounting plate 21 are adjusted (the direction is for reference Figure 1 ).

[0043] In some embodiments, a bellows is provided between the mounting plate 21 and the adjusting mechanism 20 to prevent debris from entering the adjusting mechanism 20 and affecting the normal use of the adjusting mechanism 20.

[0044] In some embodiments, a sliding groove 30 is provided at the top of the clamping plate 23, a round-headed rod 31 is slidably connected in the sliding groove 30, a second hole 33 is provided at the top of the connecting plate 22, one end of the round-headed rod 31 is inserted into the second hole 33, a first spring 32 is sleeved outside the round-headed rod 31, and both ends of the first spring 32 are fixedly connected to the round-headed rod 31 and the clamping plate 23 respectively.

[0045] When the clamping plate 23 needs to be disassembled, the round-headed rod 31 is pulled outwards. While the round-headed rod 31 slides out of the sliding groove 30, the first spring 32 is pulled. Subsequently, the clamping plate 23 is pulled outwards. After the clamping plate 23 is separated from the connecting plate 22, the disassembly of the clamping plate 23 is completed, and then the clamping plate 23 can be replaced, improving the practicality.

[0046] In some embodiments, a housing 40 is provided at the top of the mounting plate 21. A second limiting plate 41 is slidably connected inside the housing 40. A second spring 42 is provided inside the housing 40. Both ends of the second spring 42 are fixedly connected to the second limiting plate 41 and the housing 40 respectively. A limiting groove 43 is provided on one side of the clamping plate 23.

[0047] Before cleaning, when adjusting the angle of the clamping plate 23, while the clamping plate 23 drives the connecting plate 22 and the connecting seat 25 to rotate on the first limiting plate 24, after the clamping plate 23 contacts the second limiting plate 41, the second limiting plate 41 is pushed into the housing 40, and the second limiting plate 41 compresses the second spring 42. Then, after the second limiting plate 41 is aligned with the limiting groove 43, due to the resilience of the second spring 42, the second limiting plate 41 is inserted into the limiting groove 43 to fix the angles of the clamping plate 23 and the connecting plate 22, thereby facilitating subsequent cleaning operations and improving practicability.

[0048] In some embodiments, a slide rail is provided at the top of the mounting plate 21, and the housing 40 is slidably connected to the slide rail. A plurality of limiting grooves 43 are provided. By directly pushing the housing 40, the positions of the housing 40 and the second limiting plate 41 are adjusted. When the housing 40 is located at both ends of the slide rail, after rotating the clamping plate 23, the second limiting plate 41 is aligned with the limiting groove 43, which is convenient for fixing the clamping plate 23. Or when the housing 40 is located in the middle of the slide rail, the round head rod 31 is aligned with the second limiting plate 41. After rotating the clamping plate 23, the round head rod 31 contacts the second limiting plate 41. Then, the round head rod 31 pushes the second limiting plate 41 into the housing 40. Subsequently, due to the resilience of the second spring 42, the second limiting plate 41 is pressed against the round head rod 31 to limit the round head rod 31. Then, when pulling the clamping plate 23, due to the limitation of the second limiting plate 41, when the clamping plate 23 rotates, the round head rod 31 directly slides out of the clamping plate 23. After canceling the limitation of the clamping plate 23, after a batch of reinforcing bar sleeves are processed and cleaned, the clamping plate 23 can be disassembled at the same time, which is convenient for later maintenance and replacement.
