A tapping device for producing precision high-strength nuts

Abstract

This utility model discloses a tapping device for producing precision high-strength nuts, including a frame. A tapping head is mounted on the top of the frame. A movable frame is slidably engaged with the frame, and a rotating gear is rotatably mounted on the movable frame. The rotating gear has several limiting grooves, and several limiting blocks are slidably engaged with the movable frame. Limiting rods are mounted on the limiting blocks and slidably engaged within the limiting grooves. An exhaust pipe is slidably and sealingly connected to the rotating gear. By limiting the limiting rods through the limiting grooves on the rotating gear, the rotating gear can drive the limiting rods on the limiting blocks to move when it rotates, thereby compressing the nuts. A single drive source can be used to fix different nuts, reducing production costs. When the nut tapping is completed and the movable frame descends, it can compress the exhaust nozzle to open and collect debris, eliminating the need for solenoid valves or other valves to control air extraction, further reducing production costs.

Description

Technical Field

[0001] This utility model relates to the technical field of nut tapping devices, and in particular to a tapping device for the production of precision high-strength nuts. Background Technology

[0002] In existing technologies, such as the tapping device for producing precision high-strength nuts with patent number CN216151366U, multiple drive sources are generally required to fix different nuts, which increases production costs. Utility Model Content

[0003] Therefore, it is necessary to provide a tapping device for producing precision high-strength nuts to address the aforementioned technical problems.

[0004] To achieve the above objectives, this utility model provides a tapping device for producing precision high-strength nuts, including a frame, a tapping head mounted on the top of the frame, a movable frame slidably connected to the frame, a rotating gear rotatably mounted on the movable frame, a plurality of limiting grooves provided on the rotating gear, a plurality of limiting blocks slidably connected to the movable frame, limiting rods mounted on the limiting blocks, the limiting rods slidably connected to the limiting grooves, an exhaust pipe slidably and sealingly connected to the rotating gear, the output end of the exhaust pipe being connected to a vacuum generating device, an exhaust nozzle being installed inside the exhaust pipe, and a linear actuator mounted on the frame, the output end of the linear actuator being connected to the movable frame.

[0005] Preferably, a drive gear is rotatably mounted on the movable frame, and a rotary drive device is mounted on the movable frame. The output end of the rotary drive device is connected to the drive gear, and the drive gear is meshed with the rotary gear.

[0006] Preferably, the rotating gear is rotatably mounted on the movable frame via a slide rod, and the exhaust pipe is slidably and sealed to the slide rod.

[0007] Preferably, the exhaust pipe is provided with several flat grooves, and a V-shaped spring is installed in the flat groove. The output end of the V-shaped spring abuts against one of the pieces on the exhaust nozzle.

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Please see Figures 1 to 4This application provides a tapping device for producing precision high-strength nuts, including a frame 1. A tapping head 2 is mounted on the top of the frame 1. The tapping head 2 rotates to tap and can be replaced as needed. This is prior art and will not be described in detail. A movable frame 3 is slidably connected to the frame 1. A rotating gear 4 is rotatably mounted on the movable frame 3. A chip removal through hole is opened at the center of the rotating gear 4. Several limiting grooves 5 are opened on the rotating gear 4. The limiting grooves 5 are arranged in a ring around the center of the rotating gear 4 and can be arc-shaped or straight. Several limiting grooves 5 are slidably connected to the movable frame 3. A limit block 6 is provided, and a limit rod 7 is fixedly installed on the limit block 6. The limit rod 7 is slidably engaged in the limit groove 5. An exhaust pipe 8 is slidably and sealed to the rotating gear 4. The output end of the exhaust pipe 8 is connected to a vacuum generating device 9, which can be a vacuum pump. An exhaust nozzle 10 is fixedly installed inside the exhaust pipe 8. The structure of the exhaust nozzle 10 is similar to a squealing drinking spout. It will only open when the negative pressure is large enough. A linear actuator 11 is fixedly installed on the frame 1. The linear actuator 11 can be an electric cylinder. The output end of the linear actuator 11 is connected to the moving frame 3.

[0020] In this embodiment, the nut can be placed on the rotating gear 4, and then the rotating gear 4 is driven to rotate, and the limiting groove 5 on it presses the limiting rod 7, so that the limiting rod 7 can drive the limiting block 6 to slide inward. Thus, nuts of different diameters can be pressed and fixed according to the different moving distances of the limiting rods 7. After fixing, the linear actuator 11 on the frame 1 drives the moving frame 3 to move upward, so that the nut fixed on the rotating gear 4 can move to the tapping nozzle 2, and be tapped by its rotation. After tapping is completed, the linear actuator 11 drives the moving frame 3 to move downward, and after moving downward, the rotating gear 4 can be controlled to release. The nut is replaced, and the gear 4 rotates during the downward movement, which will squeeze the exhaust nozzle 10 in the exhaust pipe 8, allowing it to open. The negative pressure generated by the vacuum generator 9 can then collect the debris. The input end of the vacuum generator 9 is equipped with an air filter, dust collection box, and other waste debris collection devices to collect the debris after tapping. The input end of the vacuum generator 9 should be connected to multiple exhaust pipes 8 through a multi-head connecting hose to avoid wasting the negative pressure of the suction and to avoid excessive suction on a single exhaust nozzle 10, which would shorten its lifespan. If only one exhaust pipe 8 is connected, a small-power air pump can be used.

[0021] In some embodiments, to facilitate the rotation of the rotating gear 4, a drive gear 12 is rotatably mounted on the movable frame 3, and a rotary drive device 13 is fixedly mounted on the movable frame 3. The rotary drive device 13 can be a servo motor, and its output end is connected to the drive gear 12. The drive gear 12 meshes with the rotating gear 4. The speed of the servo motor can be customized according to actual needs, and the speed of the rotating gear 4 can be controlled by controlling the transmission ratio between the drive gear 12 and the rotating gear 4, thereby precisely controlling the rotation angle of the rotating gear 4.

[0022] In some embodiments, to facilitate the installation of the rotating gear 4, the rotating gear 4 is rotatably mounted on the movable frame 3 via a slide rod 14. The slide rod 14 is hollow and is rotatably mounted on the movable frame 3 via a bearing. The exhaust pipe 8 is slidably and sealingly connected to the slide rod 14.

[0023] In some embodiments, to increase the service life of the exhaust nozzle 10, a plurality of flat grooves are provided on the exhaust pipe 8, and a V-shaped spring piece 15 is fixedly installed in the flat groove. The output end of the V-shaped spring piece 15 abuts against one of the pieces on the exhaust nozzle 10. The flat grooves allow one end of the V-shaped spring piece 15 to be better installed in the exhaust pipe 8; in addition to the exhaust nozzle 10 being able to retract automatically, the V-shaped spring piece 15 can assist it in retracting and closing.

[0024] In some embodiments, to facilitate the fixing and limiting of the nut, a plurality of protrusions are fixedly installed on the limiting rod 7, and a locking block 16 is slidably engaged on the limiting rod 7. The locking block 16 is provided with a groove that matches the protrusions, thereby realizing the sliding engagement between the two. There should be a certain friction between the limiting rod 7 and the locking block 16, so as to prevent the nut from being taken out with it when the tapping head 2 rotates back after tapping is completed. After the previous nut is tapped and removed, the locking block 16 can be repeatedly driven forward, thereby pushing down the debris on the rotating gear 4, which facilitates the collection of debris.

[0025] In some embodiments, to facilitate the installation of the rotary drive device 13 on the movable frame 3, an L-shaped plate 17 is fixedly installed on the movable frame 3, and the rotary drive device 13 is fixedly installed on the L-shaped plate 17.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
