Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to an automatic tapping machine. Background Art

[0002] Tapping machine is a kind of machine tool that uses taps to process internal threads. It is the most widely used type of internal thread processing machine tool. According to the national machinery industry standards, the tapping machine series is divided into: desktop tapping machine-semi-automatic desktop tapping machine, vertical tapping machine, horizontal tapping machine.

[0003] At present, a Chinese utility model patent application with publication date of December 22, 2023 and publication number CN220216981U proposes an automatic tapping machine, including a base, the top of the base is fixedly connected to a machine tool, the top of one side of the base is fixedly connected to a conveyor rack, a positioning electric pusher is arranged at the top of the end of the base away from the conveyor rack, the outer walls of the positioning electric pushers are fixedly connected to two positioning racks, a tapping motor is arranged at the top of the end of the machine tool away from the positioning electric pusher, the tapping motor is fixedly connected to a fixed rack, and the positioning pusher head is pushed by the positioning electric pusher so that the positioning pusher head and the positioning block limit the nut, thereby solving the problem of stable position of the nut during processing and achieving the effect of positioning processing of the nut, and driving the tapping motor to solve the problem of processing the internal thread of the nut and achieving the effect of processing the nut, and driving the discharge pusher head by the discharge electric pusher to solve the problem of discharging the nut after processing is completed and achieving the effect of pushing the nut for discharging.

[0004] However, in reality, most nuts are square in shape. When the positioning pusher head is pushed by the positioning electric pusher so that the positioning pusher head and the positioning block limit the square nut, if the positioning block abuts against the corner of the nut edge, the thread processing position of the nut is far away from the processing position of the positioning block. When the positioning block abuts against the side wall of the nut edge, the thread processing position of the nut is close to the processing position of the positioning block. Therefore, when the positioning pusher head and the positioning block limit the square nut, it is easy to cause the thread processing position to shift, resulting in unqualified tapping, affecting production quality and efficiency; and, when the positioning pusher head and the positioning block limit different nuts, the thread processing position of the nut will also shift, resulting in unqualified tapping, affecting production quality and efficiency.

[0030] Tapping machine is a kind of machine tool that uses taps to process internal threads. It is the most widely used type of internal thread processing machine tool. According to the national machinery industry standards, the tapping machine series is divided into: desktop tapping machine-semi-automatic desktop tapping machine, vertical tapping machine, horizontal tapping machine.

[0031] However, in reality, most nuts are square in shape. When the positioning pusher is pushed by the existing positioning electric pusher so that the positioning pusher and the existing positioning block limit the square nut, if the positioning block abuts against the corner of the nut edge, the thread processing position of the nut is far away from the processing position of the positioning block. When the positioning block abuts against the side wall of the nut edge, the thread processing position of the nut is close to the processing position of the positioning block. Therefore, when the positioning pusher and the positioning block limit the square nut, it is easy to cause the thread processing position to shift, resulting in unqualified tapping, affecting production quality and efficiency; and, when the positioning pusher and the positioning block limit different nuts, the thread processing position of the nut will also shift, resulting in unqualified tapping, affecting production quality and efficiency.

[0032] Based on this, in order to improve the technical problem existing in the related art that when limiting square nuts or nuts of different specifications, the thread processing position of the nut is easily offset, affecting the processing effect, the embodiment of the present application provides the following solution.

[0033] The present application embodiment provides an automatic tapping machine, comprising:

[0034] The tapping machine body 10, the limit assembly 20, the control structure 30, the conveying mechanism 40 and the discharge mechanism 50, the tapping machine body 10 includes a workbench 11 and a tapping device 12, the tapping device 12 is arranged on the workbench 11, the limit assembly 20 includes a first clamping plate 21 and a second clamping plate 22 slidably mounted on the workbench 11, the control structure 33 controls the first clamping plate 21 and the second clamping plate 22 to move in a direction close to or away from each other, the control structure 33 includes a turntable 31, a limit plate 32, a plurality of square sliders 33 and a plurality of round sliders 34, the turntable 31 is rotatably installed in the workbench 11, the limit plate 32 is fixedly installed in the workbench 11, the turntable 31 is slidably connected to the circular slider 34 by opening a plurality of arc holes 311, the limit plate 32 is slidably connected to the square slider 33 by opening a plurality of limit holes 321, the square slider 33 is connected to the circular slider 34, the first clamping plate 21 is connected to the square slider 33 on one side of the workbench 11, the first clamping plate 21 is connected to the square slider 33 on the other side of the workbench 11, the conveying mechanism 40 is used for feeding, and the discharging mechanism 50 is used for discharging.

[0035] As can be seen from the above, in an automatic tapping machine provided by an embodiment of the present application, when it is necessary to perform internal thread processing on a nut, the conveying mechanism 40 conveys the nut to the workbench 11, rotates the turntable 31, and makes the mutually connected square slider 33 and the circular slider 34 move centripetally under the constraints of the arc hole 311 and the limit hole 321 respectively, the first clamping plate 21 and the second clamping plate 22 move in a direction approaching each other, and clamp and limit a nut on the workbench 11, start the tapping device 12, perform internal thread processing on the nut, and then perform a discharge operation on the processed nut through the discharge mechanism 50, so that the first clamping plate 21 and the second clamping plate 22 move in a direction approaching each other, and clamp and limit a nut on the workbench 11, start the tapping device 12, perform internal thread processing on the nut, and then discharge the processed nut through the discharge mechanism 50. The arrangement of the clamping plate 22, the turntable 31, the limiting plate 32, the multiple square sliders 33 and the multiple circular sliders 34, by rotating the turntable 31, the interconnected square sliders 33 and the circular sliders 34 can make centripetal motion under the constraints of the arc hole 311 and the limiting hole 321 respectively, the first clamping plate 21 and the second clamping plate 22 move in the direction of approaching each other, and the first clamping plate 21 and the second clamping plate 22 move in the direction of approaching each other The distance moved by the first clamping plate 21 and the second clamping plate 22 are the same, so that the first clamping plate 21 and the second clamping plate 22 have the same fixed position for clamping and limiting nuts of different specifications or square shapes, the nut thread processing position is not easy to shift, and the thread processing effect is improved.

[0036] Optionally, in some embodiments, please read Figure 1 to Figure 2A conveying groove 112 and a positioning groove 111 are provided on the top of the workbench 11. The conveying groove 112 is connected to the positioning groove 111. The conveying mechanism 40 includes a material sorter 41 and a first conveying plate 42. A material sorter 41 is provided on one side of the workbench 11. The material sorter 41 conveys the nuts in the material sorter 41 to the conveying groove 112 through the first conveying plate 42.

[0037] With such arrangement, when it is necessary to convey the nuts to the workbench 11, the material sorter 41 is started to sort the nuts in the material sorter 41, and the nuts are conveyed to the first conveying plate 42 in sequence by vibration. The inclined first conveying plate 42 conveys the nuts to the conveying groove 112 in sequence by vibration. The nuts in the first conveying plate 42 generate thrust on the nuts in the conveying groove 112, and move the nuts in the conveying groove 112 toward the positioning groove 111 until a single nut moves into the positioning groove 111 and abuts against the side wall of the positioning groove 111, and the conveying is stopped. Therefore, the arrangement of the material sorter 41 and the first conveying plate 42 can convey the nuts to the positioning groove 111 in sequence, and the operation is simple and convenient.

[0038] Optionally, in some embodiments, see Figure 1 to Figure 2 One end of the first conveying plate 42 is arranged on the material sorting machine 41 , and a gap is arranged between the other end and the workbench 11 .

[0039] With such arrangement, when the food processor is started, the material processor 41 will drive the first conveying plate 42 to vibrate, and the inclined first conveying plate 42 conveys the nuts through the gap to the conveying groove 112 by vibration. Therefore, the setting of the gap is used to make it difficult for the first conveying plate 42 to rub against the side wall of the workbench 11 when the first conveying plate 42 vibrates, thereby increasing the service life of the workbench 11.

[0040] Optionally, in some embodiments, see Figure 1 to Figure 2 The discharge mechanism 50 includes an electric telescopic rod 51 and a push plate 52. The push plate 52 is slidably installed on the top of the workbench 11 by opening a discharge trough 113. The electric telescopic rod 51 is set on the workbench 11, and the output end of the electric telescopic rod 51 is connected to the push plate 52.

[0041] With such arrangement, after the thread processing is completed, the electric telescopic rod 51 is started, and the push plate 52 moves until it contacts the processed nut, and the electric telescopic rod 51 is started again, and the push plate 52 moves, so that the nut moves away from the electric telescopic rod 51 and moves in the discharge trough 113, completing the pushing operation; therefore, the arrangement of the electric telescopic rod 51 and the push plate 52 can perform a pushing operation on the processed nut, and the operation is simple and convenient.

[0042] Optionally, in some embodiments, see Figure 1 to Figure 2 The discharging mechanism 50 also includes a storage box 53 and a second conveying plate 54. The storage box 53 is arranged on a side of the workbench 11 away from the electric telescopic rod 51. One end of the second conveying plate 54 is arranged on the storage box 53, and the other end is connected to the notch of the discharge trough 113.

[0043] With such arrangement, when pushing the material, the electric telescopic rod 51 is started, the pushing plate 52 moves, causing the nut to move in the direction away from the electric telescopic rod 51 until it is separated from the discharge chute 113 and moves into the second conveying plate 54, where it is accumulated in sequence. The multiple nuts in the second conveying plate 54 will fall into the storage box 53 in sequence under the thrust of the pushing plate 52. Therefore, the second conveying plate 54 and the arrangement of the second conveying plate 54 can perform storage operations on the processed nuts, and the operation is simple and convenient.

[0044] Optionally, in some embodiments, see Figures 1 to 4 The top of the workbench 11 is provided with a positioning groove 111 to slide and install the first clamping plate 21 and the second clamping plate 22. The first clamping plate 21 and the second clamping plate 22 are provided with an arc-shaped notch 23 along the side wall close to each other.

[0045] With such arrangement, when the nut is limited, the control structure 30 is used to drive the first clamping plate 21 and the second clamping plate 22 in the positioning groove 111 to move in a direction approaching each other, and the side walls on both sides of the nut abut against the side walls at the arc-shaped recess 23 to complete the limiting operation. Therefore, the arrangement of the positioning groove 111 and the arc-shaped recess 23 makes it difficult for the first clamping plate 21 and the second clamping plate 22 to shake during the sliding process, thereby improving the limiting effect of the first clamping plate 21 and the second clamping plate 22.

[0046] Optionally, in some embodiments, see Figure 3 A motor 36 is disposed at the bottom of the workbench 11 , and an output end of the motor 36 is connected to the turntable 31 .

[0047] With such arrangement, when limiting the position of the nut, the motor 36 is started, the turntable 31 rotates, and the square slider 33 and the circular slider 34 connected to each other make centripetal motion under the constraints of the arc hole 311 and the limiting hole 321 respectively, and the first clamping plate 21 and the second clamping plate 22 move in a direction approaching each other, and clamp and limit the nut on the workbench 11 to complete the limiting operation; therefore, the arrangement of the motor 36 makes it convenient for the user to use the control structure 30 to drive the first clamping plate 21 and the second clamping plate 22 in the positioning groove 111 to limit the nut.

[0048] Optionally, in some embodiments, see Figure 3 to Figure 4 A stopper 35 is fixedly connected to the bottom of the circular slider 34 , and the stopper 35 is in contact with the bottom wall of the rotating disk 31 .

[0049] With such arrangement, when the control structure 30 is started, the motor 36 is started, the turntable 31 is rotated, and the square slider 33 and the circular slider 34 connected to each other respectively make centripetal or centrifugal motion under the constraints of the arc hole 311 and the limit hole 321, and the first clamping plate 21 and the second clamping plate 22 move in the direction of approaching or moving away from each other, and the stop block 35 abuts against the bottom wall of the turntable 31, and the first clamping plate 21 and the second clamping plate 22 both abut against the bottom wall of the positioning groove 111; therefore, the setting of the stop block 35 is used to reduce the probability of the first clamping plate 21 and the second clamping plate 22 shaking during the movement.

[0050] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
