Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, specifically an automatic tapping machine. Background Technology

[0002] A tapping machine is a machining device that processes internal threads, screws, or threads on the inner surface of holes in various sizes of parts such as nuts, flanges, or metal pillars, whether through holes or blind holes. Current automatic tapping machines require a clamping device to hold the metal pillar on a worktable during operation, and then the tapping head taps the metal pillar.

[0003] Chinese Patent CN223418511U discloses an automatic tapping machine for screw production and processing, including a base, a support block, a tapping spindle head, a support plate, and a feeding mechanism. The support plate is located on one side of the base, and multiple support columns are fixedly arranged between the support plate and the base. The feeding mechanism is located on the support plate and is used to drive the multiple support columns to move sequentially to the bottom of the tapping spindle head for tapping. An clearance opening is provided on the support plate, and a dust collection bin is placed on the base, with the dust collection bin aligned with the clearance opening. Through the above technical solution, the problem of cumbersome workpiece feeding in related technologies, which affects tapping efficiency, is solved.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the structural dimensions of the feed channel, feed cylinder and other components are fixed, which can only be adapted to metal columns of specific specifications and cannot meet the processing needs of screws of multiple specifications. Furthermore, since they only rely on the arc plate and the feed channel for fixation, the metal column is prone to slight displacement during tapping, which affects the thread accuracy.

[0015] Example 1, as Figures 1 to 4 As shown, this utility model proposes an automatic tapping machine, including a base 1, a telescopic component 2, a feed plate 4, and a limiting mechanism. A translation mechanism 101 is installed on one side of the top of the base 1. The tapping machine body 102 is detachably mounted on the translation component of the translation mechanism 101. The translation mechanism 101 is existing technology and can drive the tapping machine body 102 to translate a suitable distance towards the feed plate 4. An infrared distance sensor is horizontally arranged between the translation component and the intermittent rotation mechanism 3 to monitor the distance between them in real time, improving adjustment accuracy. The tapping machine body 102... The tapping spindle head can be driven to move downwards to tap the workpiece at a suitable position on the feed plate 4. Both the tapping machine body 102 and the intermittent rotation mechanism 3 are existing technologies; their specific structures and principles are detailed in the patent with authorization announcement number CN223418511U, and will not be elaborated further. An industrial camera is installed at a suitable position on the tapping machine body 102, working in conjunction with an infrared ranging sensor to achieve precise alignment of the tapping position. The telescopic component 2 is detachably installed on the support column in the tapping machine body 102, and a retaining device is detachably installed at the output end of the telescopic component 2. The receiving seat A201 and the telescopic component 2 are hydraulic rods equipped with displacement sensors to detect the distance the receiving seat A201 moves towards the relief opening 401. This can be adjusted adaptively according to the workpiece model. A pressure sensor is installed between the telescopic component 2 and the receiving seat A201 to monitor the abutment force on the workpiece clamped in the relief opening 401 in real time. The feed plate 4 is driven to rotate intermittently by an intermittent rotation mechanism 3 installed on the other side of the top of the machine base 1. Multiple relief openings 401 are evenly distributed on the feed plate 4. The relief openings 401 are connected to the tapping machine... The main body 102 corresponds to the tapping spindle head, and the abutment seat A201 corresponds to the relief port 401. The bottom end of the relief port 401 is detachably installed with a placement seat 403, and the placement seat 403 has a through port 404. The limiting mechanism is installed in the relief port 401, including a sliding rod 505 and an abutment seat B503. Two sets of sliding rods 505 are provided, and the two sets of sliding rods 505 are symmetrically slidably connected in the relief port 401, and the sliding rods 505 are elastically connected to the side wall of the relief port 401. The abutment seat B503 is detachably connected to the end of the sliding rod 505.

[0016] Furthermore, a slot 402 is provided at the bottom of the relief opening 401 and on the feed tray 4. The placement seat 403 is slidably connected to the slot 402. An abutment plate 405 is integrally formed on the placement seat 403. The abutment plate 405 abuts against the side wall, and the abutment plate 405 and the feed tray 4 are limited and fixed by bolts.

[0017] Furthermore, the feed tray 4 has mounting grooves 501 on both sides of the relief opening 401. The side wall of the relief opening 401 has a guide opening 5, which communicates with the mounting groove 501. The top of the feed tray 4 is detachably mounted with a cover plate 502 corresponding to the open end of the mounting groove 501 by bolts. One end of the sliding rod 505 away from the abutment seat B503 extends through the guide opening 5 into the mounting groove 501 and is detachably mounted with an elastic element 506. The elastic element 506 is a spring. The other end of the elastic element 506 is detachably connected to the side wall of the mounting groove 501. A limit plate is provided on the sliding rod 505 near the elastic element 506. The limit plate abuts against the periphery of the guide opening 5 to prevent the sliding rod 505 from detaching from the mounting groove 501.

[0018] Furthermore, the guide opening 5 is set as a square opening, and the sliding rod 505 is set as a square rod. The sliding rod 505 is slidably connected to the guide opening 5 to prevent the sliding rod 505 from rotating along the guide opening 5 and interfering with the elastic element 506.

[0019] In this embodiment, the workpiece is placed into the clearance opening 401 of the feed tray 4, and the bottom of the workpiece is supported on the periphery of the opening 404 of the placement seat 403. Under the elastic force of the elastic element 506, the two sets of sliding rods 505 drive the abutment seat B503 to press against the workpiece laterally, realizing the initial positioning of the workpiece. The intermittent rotation mechanism 3 is started to drive the feed tray 4 to rotate, so that the clearance opening 401 containing the workpiece moves to the tapping station. The translation mechanism 101 is started to drive the tapping machine body 102 to translate towards the feed tray 4. The infrared distance sensor monitors the distance between the translation slider and the positioning reference block in real time. The industrial camera captures the image of the workpiece to be tapped position. The data of both are transmitted to the controller to adjust the horizontal position of the tapping machine body 102 to ensure that the tapping spindle head is coaxial with the workpiece to be tapped. The telescopic element 2 is started to drive the abutment seat. A201 moves towards the top of the workpiece, and the pressure sensor monitors the contact force in real time. When the contact force reaches the set value, the telescopic component 2 stops moving, completing the final fixation of the workpiece and making the workpiece stably limited in the relief port 401. The controller starts the tapping machine body 102 to drive the tapping spindle head to move down to tap the workpiece. The waste generated during the tapping process falls into the top of the machine base 1 through the through port 404 of the placement seat 403. After the tapping is completed, the tapping spindle head resets, the telescopic component 2 drives the contact seat A201 to retract, and the intermittent rotation mechanism 3 drives the feed plate 4 to rotate, moving the next relief port 401 with the workpiece to the tapping station and starting the next work cycle. The processed workpiece can be quickly removed from between the two sets of contact seats B503 and replaced with a new workpiece to be processed, making loading and unloading convenient and fast.

[0020] Example 2, as Figure 3 and Figure 4 As shown, the automatic tapping machine proposed in this utility model, compared with the first embodiment, has multiple sets of abutment seats B503. The end of the abutment seat B503 away from the sliding rod 505 is set as the abutment end. The abutment end is preset with various shapes such as arc shape, V shape, etc. The shape of the abutment end is adapted to the model of the workpiece to be processed, which improves the clamping tightness. The end of the mounting groove 501 away from the abutment end is integrally formed with a socket 504. The sliding rod 505 slides into the inner wall of the socket 504 and is limited and fixed by fastening bolts. The structure of the abutment seat A201 is the same as that of the abutment seat B503.

[0021] Furthermore, the placement seat 403 is provided with multiple sets, and the through-holes 404 on the placement seat 403 are prefabricated with various models and sizes. The through-holes 404 are adapted to the model of the workpiece to be processed, which facilitates the support of the workpiece, facilitates tapping, and at the same time facilitates the processing waste to fall into the machine base 1 through the through-holes 404 for easy cleaning.

[0022] In this embodiment, by removing the fastening bolts, the socket 504 and the sliding rod 505 can be separated, allowing other types of abutment seats B503 to be installed and fixed to the sliding rod 505. Simultaneously, the corresponding type of abutment seat A201 is installed to the output end of the telescopic component 2 in the same manner, and then the corresponding type of placement seat 403 is installed to the slot 402, ensuring that the through port 404 matches the type of workpiece to be processed. Before processing different types of workpieces, the controller activates the translation mechanism 101 to move the tapping machine body 102 a suitable distance toward the feed plate 4. During this process, the industrial camera and infrared ranging sensor work together to ensure stable clamping and support of the workpiece, preventing deviation during tapping, improving tapping quality, and broadening the applicability range.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
