Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of nut processing technology, and more specifically, to a nut tapping machine with a loading and unloading device. Background Technology
[0002] Nut tapping is a metal cutting process for machining threads on the inner wall of a nut. It typically uses a tap to create a standard thread in a pre-drilled hole through rotational cutting. The steps include: first, drilling a hole to the thread root diameter; then, selecting a matching tap, applying axial pressure and rotating it to cut a helical groove, forming a female thread that can fit the bolt. When tapping, attention should be paid to lubrication and cooling, feeding in stages to avoid tap breakage, and ensuring thread accuracy. This process is widely used in mechanical assembly, automobile manufacturing, and other fields, and is one of the core links in fastener production.
[0003] In the existing technology, operators often use corresponding nut tapping machines to tap the inside of the nuts during the nut processing process, and most of them use nut vibratory feeders for feeding. However, in actual use, although existing nut tapping machines have basic tapping functions, they generally need to stop frequently during the processing to wait for the equipment to complete the loading and unloading operations, which significantly reduces the overall tapping efficiency of the equipment. Therefore, it is necessary to improve them. Utility Model Content

[0006] As a preferred technical solution of this disclosure, a fixing ring is movably connected to the bottom of the material tray, the fixing ring is fixedly installed inside the base, and fixing rods are fixedly connected to the front and rear sides of the bottom of the fixing ring. A collection box is movably connected to the left side of the bottom of the base cavity.
[0007] As a preferred technical solution of this disclosure, hexagonal grooves are evenly formed around the top of the tray, and the number of hexagonal grooves is four, with all four hexagonal grooves having the same size.
[0008] As a preferred technical solution of this disclosure, the bottom of the fixing ring is fixedly connected to a feeding plate, and the bottom end of the feeding plate is located directly above the top of the inner cavity of the collection box.
[0009] As a preferred technical solution of this disclosure, a nut vibrating plate body is fixedly connected to the right side of the top of the base, a fixing frame is fixedly connected to the rear of the top of the base, and a reinforcing rib is fixedly connected to the inner side of the fixing frame.
[0010] As a preferred technical solution of this disclosure, a second pneumatic cylinder is fixedly connected to the top of the fixed frame, the bottom end of the second pneumatic cylinder passes through the fixed frame and extends to the bottom of the fixed frame and is fixedly connected to a second protective shell, a second motor is fixedly connected inside the second protective shell, a second rotating shaft is fixedly sleeved at the other end of the output shaft of the second motor, and a tap is fixedly connected to the other end of the second rotating shaft.
[0011] As a preferred technical solution of this disclosure, the bottom of both sides of the second protective shell is fixedly connected to a fixing plate, a telescopic rod is movably sleeved inside the fixing plate, and a fixing block is fixedly connected to the top of the telescopic rod.
[0012] As a preferred embodiment of this disclosure, a spring is movably sleeved on the outer surface of the telescopic rod, the top of the spring is fixedly connected to the bottom end of the fixing block, and the bottom end of the spring is fixedly connected to the top of the fixing plate.
[0013] As a preferred technical solution of this disclosure, the bottom end of the telescopic rod passes through the fixed plate and extends to the bottom of the fixed plate and is fixedly connected to a connecting plate, and a pressure ring is fixedly connected between the connecting plates.
[0014] As a preferred embodiment of this disclosure, the number of telescopic rods is two, the two telescopic rods are of the same size, and the outer surfaces of the two telescopic rods are smooth.
[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] 1. This disclosure uses a first rotating shaft, a rotating rod, a mounting rod, a fixed rod, and a material tray. Starting the first motor causes the first rotating shaft to rotate, which in turn pushes the mounting rod, causing the material tray to rotate under the limiting action of the base. When the rotating rod rotates 90 degrees, it collides with the fixed rod, thus limiting the rotation angle of the rotating rod. At this point, the material tray rotates 90 degrees, causing the next hexagonal groove to move directly below the tap. Then, the first pneumatic cylinder is activated, causing the first protective shell and the rotating rod to move vertically downwards. When the rotating rod disengages from the mounting rod, the first motor is activated again, causing the rotating rod to rotate in the opposite direction. Similarly, when the rotating rod is blocked by the fixed rod, the first pneumatic cylinder is activated again, causing the first motor to drive the rotating rod to reset, thus achieving a 90-degree directional rotation. This avoids frequent waiting for loading and unloading after processing, improving the processing efficiency of the equipment.
[0017] 2. This disclosure incorporates a telescopic rod, a fixing block, a connecting plate, a pressure ring, and springs. When the second pneumatic cylinder is activated, the second protective shell causes the pressure ring to move vertically downwards. Once the pressure ring and connecting plate contact the nut located inside the hexagonal groove, they cannot move further downwards. At this point, the downward pressure of the second pneumatic cylinder causes the two springs to be in a stretched state. Through the elastic force of the two springs, the nut is clamped. After processing is completed, the tap is rotated in the opposite direction, causing the tap to disengage from the nut. The second pneumatic cylinder is then activated again, causing the second protective shell to move the pressure ring upwards. Since the pressure ring has not returned to its initial position, the springs still have an elastic force, ensuring that the pressure ring and connecting plate maintain downward pressure on the nut until the tap is completely disengaged. This design eliminates the need for complete nut fixing, saving the step of fixing the nut separately and improving the processing efficiency of the equipment. Attached Figure Description

Detailed Implementation
[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0028] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0029] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.
[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] like Figures 1-5 As shown, a nut tapping machine with loading and unloading device according to an embodiment of the present disclosure is illustrated. It includes a base 1, a first pneumatic cylinder 2 fixedly connected to the bottom of the inner cavity of the base 1, a first protective shell 3 fixedly connected to the top of the first pneumatic cylinder 2, a first motor 4 fixedly connected inside the first protective shell 3, a first rotating shaft 5 fixedly sleeved at the other end of the output shaft of the first motor 4, a rotating rod 6 fixedly sleeved at the other end of the first rotating shaft 5, an installation rod 7 movably connected inside the rotating rod 6, a material tray 9 fixedly connected to the top of the installation rod 7, and the outer surface of the material tray 9 movably sleeved with the inner part of the top of the base 1.
[0032] The design of the first protective shell 3 achieves the function of sealing the first motor 4, preventing dust and tapping debris from entering the interior of the first motor 4 and affecting its service life. At the same time, there are four mounting rods 7, and the four mounting rods 7 are the same size and the outer surface of the four mounting rods 7 is smooth, which makes the sliding of the mounting rods 7 inside the rotating rod 6 smoother.
[0033] In some examples, a fixing ring 10 is movably connected to the bottom of the tray 9. The fixing ring 10 is fixedly installed inside the base 1. Fixing rods 8 are fixedly connected to the front and rear sides of the bottom of the fixing ring 10. A collection box 13 is movably connected to the left side of the bottom of the inner cavity of the base 1.
[0034] The symmetrical design of the two fixed rods 8 is to limit the rotation angle of the rotating rod 6, so that the rotation range of the rotating rod 6 is always ninety degrees.
[0035] In some examples, hexagonal grooves 11 are evenly distributed around the top of the tray 9. There are four hexagonal grooves 11, and the four hexagonal grooves 11 are all the same size.
[0036] The design of the four hexagonal slots 11 allows the device to feed materials on one side while unloading them on the other, eliminating the need for the equipment to stop and wait for the loading and unloading process, thus improving the processing efficiency of the equipment.
[0037] In some examples, the bottom of the retaining ring 10 is fixedly connected to the discharge plate 12, and the bottom end of the discharge plate 12 is located directly above the top of the inner cavity of the collection box 13.
[0038] The inclined design of the inner wall of the feed plate 12 allows the processed nuts to slide down to the bottom of the inner cavity of the feed plate 12 under the guidance of the feed plate 12 before falling, thus avoiding the nuts from falling directly from a height and causing surface damage.
[0039] In some examples, a nut vibrating plate body 14 is fixedly connected to the right side of the top of the base 1, a fixing frame 15 is fixedly connected to the rear of the top of the base 1, and a reinforcing rib 21 is fixedly connected to the inner side of the fixing frame 15.
[0040] The design of the reinforcing rib 21 improves the connection strength of the fixed frame 15 and reduces the amplitude of vibration or shaking during equipment operation.
[0041] In some examples, a second pneumatic cylinder 16 is fixedly connected to the top of the mounting bracket 15. The bottom end of the second pneumatic cylinder 16 passes through the mounting bracket 15 and extends to the bottom of the mounting bracket 15 and is fixedly connected to a second protective shell 17. A second motor 18 is fixedly connected inside the second protective shell 17. A second rotating shaft 19 is fixedly sleeved at the other end of the output shaft of the second motor 18. A tap 20 is fixedly connected to the other end of the second rotating shaft 19.
[0042] Due to the design of the second protective shell 17, wire chips are prevented from flying into the interior of the second motor 18 during the tapping process, thus avoiding short circuits in the second motor 18 and improving the service life of the second motor 18.
[0043] In some examples, the bottom of the left and right sides of the second protective shell 17 is fixedly connected to a fixing plate 22, and a telescopic rod 23 is movably sleeved inside the fixing plate 22. A fixing block 24 is fixedly connected to the top of the telescopic rod 23.
[0044] The design of the fixing block 24 is to prevent the telescopic rod 23 from moving too much during subsequent telescopic movements, thereby causing it to detach from the inside of the fixing plate 22, and thus limiting the travel of the telescopic rod 23.
[0045] In some examples, a spring 27 is movably sleeved on the outer surface of the telescopic rod 23, with the top of the spring 27 fixedly connected to the bottom of the fixing block 24 and the bottom of the spring 27 fixedly connected to the top of the fixing plate 22.
[0046] Due to the elastic force of spring 27, telescopic rod 23 has a good reset effect during subsequent movement.
[0047] In some examples, the bottom end of the telescopic rod 23 passes through the fixing plate 22 and extends below the fixing plate 22 and is fixedly connected to the connecting plate 25, and a pressure ring 26 is fixedly connected between the connecting plates 25.
[0048] Both connecting plates 25 and the pressure ring 26 are made of hard rubber, which prevents the surface of the nut from being scratched during the subsequent tightening and fixing process.
[0049] In some examples, there are two telescopic rods 23, both of which are the same size and have smooth outer surfaces.
[0050] This design allows the telescopic rod 23 to move more smoothly inside the fixed plate 22 and reduces the friction between the telescopic rod 23 and the fixed plate 22.
[0051] The working principle and usage process of this disclosure are as follows:
[0052] First, the second pneumatic cylinder 16 is activated, causing the second motor 18 to drive the tap 20 downwards. When the pressure ring 26 and connecting plate 25 contact the nut located inside the hexagonal groove 11, they cannot move further downwards. At this time, due to the downward pressure of the second pneumatic cylinder 16, the two springs 27 are in a stretched state. The elastic force of the two springs 27 achieves the clamping effect on the nut. Then, the second motor 18 is activated, causing the second rotating shaft 19 to drive the tap 20 to start rotating. At this time, the tapping operation of the nut will be performed. After the processing is completed, the second motor 18 is activated to rotate the tap 20 in the opposite direction, causing the tap 20 to disengage from the nut. The second pneumatic cylinder 16 is activated again, causing the second protective shell 17 to drive the pressure ring 26 upwards. At this time, since the pressure ring 26 has not returned to its initial position, the springs 27 still have an elastic effect, thus ensuring that the pressure ring 26 and connecting plate 25 can always apply downward pressure to the nut before the tap 20 completely disengages from the nut. This design eliminates the need to completely fix the nut, saving the step of fixing the nut separately and improving the processing efficiency of the equipment.
[0053] After one machining operation is completed and tap 20 is reset, the first motor 4 is started, causing the first rotating shaft 5 to drive the rotating rod 6 to rotate. This causes the rotating rod 6 to press and push the mounting rod 7, which in turn causes the mounting rod 7 to drive the material tray 9 to rotate under the limiting action of the base 1. When the rotating rod 6 rotates 90 degrees, it will collide with the fixed rod 8, thus limiting the rotation angle of the rotating rod 6. At this time, the material tray 9 rotates 90 degrees, causing the next hexagonal groove 11 to move directly below tap 20. Then, the first pneumatic cylinder 2 is started, causing the first protective shell 3 and the rotating rod 6 to move vertically downwards. After the rotating rod 6 disengages from the inside of the mounting rod 7, the first motor 4 is started again, causing the rotating rod 6 to rotate vertically downwards. The moving rod 6 rotates in the opposite direction. Similarly, after the rotating rod 6 is blocked by the fixed rod 8, the first pneumatic cylinder 2 is activated again, causing the first motor 4 to drive the rotating rod 6 to reset, thereby achieving the purpose of directional rotation of 90 degrees. This avoids the equipment from having to wait frequently for loading and unloading after processing, thus improving the processing efficiency of the equipment. At the same time, after the material tray 9 rotates 90 degrees, the nuts that were processed last time will fall into the collection box 13 through the through hole opened on the fixed ring 10 and under the guidance of the unloading plate 12, realizing automatic unloading. Since the specific structure and working principle of the nut vibrating plate body 14 are existing technologies well known to those skilled in the art, they will not be elaborated on here.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
