Description

Technical Field

[0001] This utility model relates to the field of round nut processing, specifically an automatic tapping device for round nuts. Background Technology

[0002] Round nuts are often used with locking washers. During assembly, the inner tongue of the washer is inserted into the groove on the shaft, and the outer tongue of the washer is inserted into the groove of the round nut, thus locking the nut. Tapping refers to using a certain torque to screw a tap into the hole to be drilled to produce internal threads. Round nuts have internal threads, requiring a tapping device. A search reveals an automatic tapping device for round nuts disclosed in application number CN202222125411.6, which describes a device including damping pads evenly spaced inside and at the lower end of the fixture, which can reduce vibration during the tapping process of round nuts. Vibration improves machining quality, the tap descent speed is adjustable, the slider descends rapidly during idle stroke, and after machining is completed, the clamp is opened, and the round nut automatically falls onto the conveyor belt, improving machining and transportation efficiency and solving the problem of unloading round nuts. However, the above description still has the following defects in actual use: the tapping machine cannot automatically feed round nuts and continuously process them. At the same time, during the unloading process, the round nuts are prone to falling and rolling to the side, affecting work efficiency. Therefore, it is necessary to design a more practical automatic tapping machine for round nuts. Utility Model Content

[0022] Please see Figure 1-Figure 4 An automatic tapping device for round nuts includes a worktable 1, a mounting plate 11 on one side of the top of the worktable 1, a rotating plate 12 rotatably connected to the top of the mounting plate 11, a feeding component 2 on one side of the mounting plate 11, and a limiting component 3 on the other side of the mounting plate 11.

[0023] Please see Figure 3 The feeding assembly 2 includes a strip block 21 installed on one side of the mounting plate 11. A strip groove 22 is opened on the top of the strip block 21. A drive motor 23 is provided on the lower side of one side of the inner wall of the strip groove 22. The output shaft of the drive motor 23 is fixedly connected to one end of the drive roller 24. The other end of the drive roller 24 is rotatably connected to the lower side of the other side of the inner wall of the strip groove 22. A conveyor belt 25 is sleeved on the surface of the drive roller 24. The other side of the inner wall of the conveyor belt 25 is sleeved on the surface of the driven roller 26. The two ends of the driven roller 26 are rotatably connected to the lower sides of the inner wall of the strip groove 22. An auxiliary groove 27 is opened on the upper side of both sides of the inner wall of the strip groove 22. Several rubber auxiliary rollers 28 are provided on the inner wall of each of the two auxiliary grooves 27.

[0024] In practical use: the drive motor 23 drives the active roller 24 to rotate, the active roller 24 drives the conveyor belt 25 and the driven roller 26 to rotate, thereby causing the conveyor belt 25 to move several round nuts on its surface. In conjunction with several rubber auxiliary rollers 28 on the inner wall of the two auxiliary grooves 27, the movement of several round nuts is limited, increasing the stability of automatic feeding, so that the round nuts can stably enter the placement groove 110 on the side of the rotating disk 12 to complete the feeding.

[0025] Please see Figure 4The limiting component 3 includes a strip plate 31 installed on the other side of the mounting plate 11. A mounting base 32 is provided on one side of the top of the strip plate 31. An electric push rod 33 is provided on one side of the mounting base 32.

The guide rod 39 of the inner wall of the through hole is inserted and connected to the inner wall of the sliding groove 38.

[0026] In practical use: the electric push rod 33 on the mounting base 32 drives the moving block 34 to move, and the moving block 34 drives the slider 37 to move on the surface of the guide rod 39 in the groove 38, thereby limiting its movement. The moving block 34 drives the limiting tooth 35 to engage with the two through grooves 18 on the arc-shaped limiting ring 17, so that the inner wall of the groove 36 engages with the protrusion. At this time, the end of the limiting tooth 35 engages with the gap between the placement groove 110 and the round nut, completing the engagement and fixation of the round nut.

[0027] Please see Figure 4 The top of the mounting plate 11 has a groove 13, and the bottom of the inner wall of the groove 13 has a rotary motor 14. The surface of the output shaft of the rotary motor 14 is inserted and connected to the surface of the load-bearing plate 15. The top surface of the output shaft is rotatably connected to the middle of the surface of the rotating plate 12. A fixing ring 16 is provided at the top of the output shaft.

[0028] In practical use: the rotary motor 14, together with the output shaft and the fixed ring 16, drives the rotary disk 12 to rotate, and the rotary disk 12 drives several round nuts to rotate, thereby realizing processing. When the processing is completed, the round nuts enter the storage box 118 according to the inertia of rotation to complete the unloading.

[0029] Please see Figure 4 The top edge of the mounting plate 11 is provided with an arc-shaped limiting ring 17. The inner wall of the arc-shaped limiting ring 17 is rotatably connected to the side of the rotating plate 12. The inner wall of the arc-shaped limiting ring 17 has two through grooves 18. The inner walls of the two through grooves 18 are interlocked with the teeth of the limiting teeth 35. The protrusion between the inner walls of the two through grooves 18 is engaged with the inner wall of the slot 36.

[0030] The top side of the load-bearing plate 15 has several processing grooves 19, and the top side of the rotating plate 12 has several placement grooves 110. The inner walls of the several placement grooves 110 can be fitted with round nuts, and the gap between the inner wall of the placement groove 110 and the round nuts is engaged with the surface of the limiting teeth 35.

[0031] In practical use: the moving block 34 drives the limiting tooth 35 to engage with the two through slots 18 on the arc-shaped limiting ring 17, so that the inner wall of the slot 36 engages with the protrusion. At this time, the end of the limiting tooth 35 engages with the gap between the placement slot 110 and the round nut, thus completing the engagement and fixation of the round nut.

[0032] Please see Figure 2 The workbench 1 has a mounting bracket 111 on one side of the top edge. The mounting bracket 111 has an electric hydraulic rod 112 on one side of the top. The telescopic end of the electric hydraulic rod 112 is fixedly connected to a mounting block 113. The bottom of the mounting block 113 is equipped with a servo motor 114. The output shaft of the servo motor 114 is fixedly connected to a tapping head 115.

[0033] In practical use: the electric hydraulic rod 112 drives the mounting block 113 to move, and the mounting block 113 drives the tapping head 115 to move until it approaches the round nut. Then, the servo motor 114 drives the tapping head 115 to rotate, thereby processing the inner wall of the round nut.

[0034] Please see Figure 2 A slot is provided on the edge of the other side of the top of the workbench 1. A support frame 116 is engaged with the inner wall of the slot. One side of the inner wall of the support frame 116 is rotatably connected to the connecting shaft 119 on one side of the storage box 118 through a bushing 117. The connecting shaft 119 on the other side of the storage box 118 is rotatably connected to the other side of the inner wall of the support frame 116. A rotating handle 120 is provided at the port of the other end of the connecting shaft 119.

[0035] In practical use: The storage box 118 collects the processed round nuts. When a certain number are collected, the rotating handle 120 is rotated, which drives the two connecting shafts 119, the storage box 118 and the bushing 117 to rotate, thereby adjusting the angle of the storage box 118 so that the large round nuts inside can be tilted out.

[0036] Please see Figure 1 A control panel 121 is located at one corner of the top of the workbench 1. The rotary motor 14, the electric hydraulic rod 112, the servo motor 114, the drive motor 23, and the electric push rod 33 are all electrically connected to an external power source through the control panel 121.

[0037] In practical use: The control panel 121 is used to control the rotary motor 14, the electric hydraulic rod 112, the servo motor 114, the drive motor 23 and the electric push rod 33, so as to facilitate the automatic feeding, fixing and processing of round nuts by the device.

[0038] In use, the drive motor 23 drives the active roller 24 to rotate, which in turn drives the conveyor belt 25 and the driven roller 26 to rotate. This causes the conveyor belt 25 to move several round nuts on its surface. In conjunction with several rubber auxiliary rollers 28 on the inner walls of the two auxiliary grooves 27, the movement of the round nuts is limited, increasing the stability of automatic feeding. This allows the round nuts to stably enter the placement groove 110 on the side of the rotating disk 12 to complete the feeding. The electric push rod 33 on the mounting base 32 drives the moving block 34 to move. The moving block 34 drives the slider 37 to move on the surface of the guide rod 39 in the slide groove 38, limiting its movement. The moving block 34 drives the limiting tooth 35 to engage with the two through grooves 18 on the arc-shaped limiting ring 17, so that the inner wall of the groove 36 engages with the protrusion. At this time, the end of the limiting tooth 35 engages with the gap between the placement groove 110 and the round nut, completing the engagement and fixation of the round nut.
