Description
Technical Field
[0001] This utility model belongs to the field of parts tapping technology, specifically relating to a dual-servo automatic tapping machine. Background Technology
[0002] A tapping machine is a mechanical processing device that processes internal threads, screws, or threads on the inner surface of holes in various parts such as machine housings, equipment end faces, nuts, and flanges with different specifications of through holes or blind holes; tapping machines are also called thread tapping machines, thread tapping machines, automatic tapping machines, etc.
[0003] Currently, the processing and production of similar products in the industry generally involves positioning parts using simple fixtures, and completing the tapping process by manual feeding, semi-automatic tapping machine processing, and manual material removal. This method is inefficient, and the processing quality is difficult to guarantee, and there may even be instances of missed processing. Utility Model Content
[0004] In order to overcome the problems of low production efficiency caused by the need for manual loading and unloading of current tapping machines and the use of single-axis tapping, this utility model provides a dual-servo automatic tapping machine, which aims to automate loading and unloading to reduce labor costs while improving product production efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A dual-servo automatic tapping machine includes a frame, a machine platform mounted on the frame, a vibratory feeder on one side of the frame, a linear vibrator connected to the vibratory feeder's discharge port, the linear vibrator being fixedly mounted on the machine platform, and an automatic feeding mechanism connected to the end of the linear vibrator away from the vibratory feeder. A tapping mechanism is also provided on the machine platform, located on one side of the automatic feeding mechanism.
[0007] Furthermore, the tapping mechanism includes a stand, which is fixedly disposed on one side of the surface of the machine base plate. A mounting platform is slidably disposed on the side of the stand near the automatic feeding mechanism near the top. A second servo motor is provided at the top of the mounting platform, and two tapping taps are evenly disposed at the bottom of the mounting platform. Vertical and parallel first slide rails are provided on both sides of the end of the stand near the mounting platform, and a first slider that slides and adapts to the first slide rails is provided on the side of the mounting platform near the stand. A first servo motor for driving the mounting platform is provided at the top of the side of the stand where the mounting platform is disposed.
[0008] Furthermore, the automatic feeding mechanism includes a feeding platform, which is fixedly mounted on the machine base plate. A material sliding channel is provided in the middle of the feeding platform. The material sliding channel includes two oppositely arranged slide rails. A horizontally arranged groove is opened on the opposite side surface of the two slide rails. Both ends of the groove are designed to be through. One side of the material sliding channel is connected to the linear vibrator. Several notches are evenly and spaced apart at the top of the two slide rails near the discharge port. The notches are connected to the grooves.
[0009] An induction feeding mechanism is also mounted above the side of the material feeding channel near the vibrator, and a clamping mechanism is also movably mounted on the feeding platform. The clamping mechanism is located on the side of the induction feeding mechanism away from the vibrator and is located below the tapping tap.
[0010] Furthermore, the inductive feeding mechanism includes two opposing second slide rails, which are located on both sides of the material channel. Each second slide rail is fitted with a second slider. A second mounting plate is provided at the top of each slider. A cylinder is mounted on the top center of the second mounting plate via several support columns. A top shaft is movably mounted at the end of the cylinder near the second mounting plate, and the end of the top shaft away from the cylinder passes through the second mounting plate. The vertical projection of the top shaft falls entirely within the gap between the two slide rails. An infrared sensor is also provided at the bottom of the second mounting plate. An electric telescopic rod is connected to the top of the second mounting plate near the vibrator. The electric telescopic rod is horizontally positioned and fixedly mounted on a first mounting plate. The first mounting plate is supported on two opposing fixed blocks located on both sides of the material channel. The signal output point of the infrared sensor is connected to the signal input ends of the cylinder and the electric telescopic rod.
[0011] Furthermore, the clamping mechanism includes two opposing clamping blocks. The bottom end of the opposing side of each clamping block is provided with a plurality of protrusions that correspond to and fit the notch. The clamping blocks are movably connected to the feeding platform via an electric rotating rod, which is movably embedded in the feeding platform.
[0012] Furthermore, a discharge roller is movably provided near the end of the discharge port of the material sliding channel, and the projection of the discharge roller in the vertical direction falls completely within the gap between the two side rails of the sliding channel.
[0013] The beneficial effects of this utility model are:
[0014] By incorporating an induction feeding mechanism and unloading rollers, the tapping machine achieves automated loading and unloading, replacing manual loading and unloading. The dual-axis tapping system saves manpower and improves production efficiency. Furthermore, the automatic feeding mechanism features a sliding channel with two opposing slide rails. Each of the opposing slide rails has a horizontally positioned groove on its side surface, with both ends of the groove being through-holes. These grooves perfectly align with the straight edges of the workpiece on both sides, allowing the workpiece's edges to engage with the two opposing grooves and move along them. This provides initial positioning of the workpiece, facilitating further fixing and tapping. Additionally, after entering the sliding channel, the workpiece slides smoothly against the grooves, and the two opposing slide rails lift several workpieces, suspending their bottoms. This ensures that the holes in the workpiece are unobstructed from both above and below, facilitating tapping operations and eliminating concerns about the tapping tap damaging the bottom feeding platform, thus guaranteeing the safety of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 As shown, this utility model is a dual-servo automatic tapping machine, including a frame 1, a machine base plate 11 mounted on the frame 1, a vibratory feeder 2 on one side of the frame 1, a linear vibrator 13 connected to the vibratory discharge port 21 of the vibratory feeder 2, the linear vibrator 13 being fixedly mounted on the machine base plate 11, and an automatic feeding mechanism connected to the end of the linear vibrator 13 away from the vibratory feeder 2. A tapping mechanism is also mounted on the machine base plate 11, located on one side of the automatic feeding mechanism. The tapping mechanism includes a stand 12, which is fixedly mounted on one side of the surface of the machine base plate 11, with the stand 12 positioned near the top of the side closest to the automatic feeding mechanism. A mounting platform 124 is slidably arranged. A second servo motor 122 is provided at the top of the mounting platform 124, and two tapping taps 125 are evenly arranged at the bottom of the mounting platform 124. The second servo motor 122 is used to drive the two tapping taps 125 to operate. A vertical and parallel first slide rail 123 is provided on both sides of the end of the stand 12 near the mounting platform 124. A first slider 1240 that is slidably adapted to the first slide rail 123 is provided on the side of the mounting platform 124 near the stand 12. A first servo motor 121 for driving the mounting platform 124 is provided at the top of the side of the stand 12 where the mounting platform 124 is located.
[0023] The automatic feeding mechanism includes a feeding platform 126, which is fixedly mounted on the machine base plate 11. A material conveying channel is provided in the middle of the feeding platform 126. The material conveying channel includes two opposing slide rails 127. Each of the opposing sides of the two slide rails 127 has a horizontally arranged groove 1271. Both ends of the groove 1271 are through-holes. One side of the material conveying channel is connected to the vertical vibrator 13. Furthermore, the grooves 1271 are adapted to the straight edges on both sides of the workpiece 3 in this invention. That is, when several workpieces 3 are sequentially conveyed to the material conveying channel by the vertical vibrator 13, the edges of the workpieces 3 are precisely engaged in the two opposing grooves 1271 and move along the grooves 1271. On the one hand, the workpiece 3 is initially limited, which facilitates the subsequent fixation and tapping of the workpiece 3. On the other hand, after the workpiece 3 enters the sliding channel, the two sides of the workpiece 3 slide and adapt to the groove 1271, and the two opposite sliding side rails 127 support several workpieces 3, so that the bottom of the workpiece 3 is suspended, and thus the hole in the middle of the workpiece 3 is unobstructed from top to bottom. This not only facilitates the tapping operation of the workpiece 3, but also eliminates the worry that the tapping tap 125 will damage the bottom feeding platform 126, ensuring the safety of the equipment operation. In addition, in order to facilitate the subsequent clamping of the workpiece 3, several notches 1272 are evenly and spaced at the top of the two sliding side rails 127 near the discharge port. The notches 1272 are connected to the groove 1271.
[0024] To facilitate the automatic sliding of several workpieces 3 on the slide channel and achieve automatic feeding, an inductive feeding mechanism 14 is also installed above the side of the slide channel near the vibrator 13. Specifically, the inductive feeding mechanism 14 includes two opposing second slide rails 146, which are located on both sides of the slide channel. Each of the two second slide rails 146 is fitted with a second slider 145. A second mounting plate 144 is provided at the top of each of the two second sliders 145. The top of the second mounting plate 144 is connected by several... A cylinder 147 is mounted on the dry support column 148. A top shaft 149 is movably mounted on one end of the cylinder 147 near the second mounting plate 144. The end of the top shaft 149 away from the cylinder 147 passes through the second mounting plate 144, and the vertical projection of the top shaft 149 falls completely within the gap between the two slide rails 127. An infrared sensor is also provided at the bottom of the second mounting plate 144, and an electric telescopic rod 143 is connected to the top of the second mounting plate 144 near the vibrator 13. The electric telescopic rod 143 extends... The device is horizontally positioned, with the electric telescopic rod 143 fixedly mounted on the first mounting plate 142. The first mounting plate 142 is mounted on two opposing fixed blocks 141, which are located on both sides of the material sliding channel. The signal output point of the infrared sensor is connected to the signal input terminals of the cylinder 147 and the electric telescopic rod 143. When the workpiece 3 enters the material sliding channel through the vibrator 13 and passes through the induction feeding mechanism 14, the infrared sensor immediately sends a drive signal to the cylinder 147 and the electric telescopic rod 143 after sensing the workpiece 3. The cylinder 147 starts and drives the top shaft 149 to extend towards the workpiece 3 and abut against the surface of the workpiece 3. Then, the electric telescopic rod 143 extends and drives the second mounting plate 144 to slide along the second slide rail 146, thereby driving a workpiece 3 to move and be transferred along the material sliding channel towards the bottom of the tapping mechanism. After the transfer of a workpiece 3 is completed, the top shaft 149 retracts and the electric telescopic rod 143 shortens, driving the second mounting plate 144 back to its initial position and continuing the induction feeding operation.
[0025] Meanwhile, a clamping mechanism 15 is also movably installed on the feeding platform 126. The clamping mechanism 15 is located on the side of the induction feeding mechanism 14 away from the direct vibrator 13, and is located below the tapping tap 125. Specifically, the clamping mechanism 15 includes two opposing clamping blocks 151. The bottom end of the opposing side of the clamping blocks 151 is provided with several protrusions that correspond to and fit the notch 1272. The clamping blocks 151 are movably connected to the feeding platform 126 through an electric rotating rod 152. The workpiece 3 is dynamically embedded in the feeding platform 126. When the workpiece 3 moves along the sliding channel, it passes through the clamping mechanism 15. At this time, the electric rotating rod 152 rotates and drives the clamping block 151 to move, so that the protrusion at the bottom of one side of the clamping block 151 is engaged with the notch 1272 at the top of the corresponding slide rail 127 that matches the protrusion. At this time, the protrusion abuts against the two sides of the workpiece 3 through the notch 1272, thereby limiting and clamping it to prevent the workpiece 3 from shifting during subsequent tapping operations and affecting the quality of the workpiece.
[0026] In order to achieve automated material feeding, a feeding roller 16 is also movably installed near the end of the material feeding channel near the discharge port. The projection of the feeding roller 16 in the vertical direction falls completely into the gap between the two slide rails 127.
[0027] The working principle of this utility model:
[0028] In use, this device is installed at the discharge port of the production parts. The vibratory feeder 2 is aligned with the discharge port. By starting the vibratory feeder 2, the parts are arranged sequentially through the vibratory discharge port 21 and enter the linear vibrator 13. The linear vibrator 13 continues to vibrate, thereby pushing several workpieces 3 to be transported linearly along the linear vibrator 13 and sequentially enter the sliding channel. When the parts pass the induction feeding mechanism 14, the infrared sensor at the bottom of the second mounting plate 144 senses the workpiece 3. At this time, the cylinder 147 starts the belt. The moving top shaft 149 extends towards the workpiece 3 and abuts against the surface of the workpiece 3. Then, the electric telescopic rod 143 extends, driving the second mounting plate 144 to slide along the second slide rail 146. When the inductive feeding mechanism 14 moves a workpiece 3 to one side of the clamping mechanism 15, the length of the second slide rail 146 is limited, and the workpiece 3 cannot be completely fed into the clamping mechanism 15. At this time, since the vibrator 13 is still continuously transmitting several workpieces 3 into the sliding channel, each workpiece 3 entering the sliding channel will push the workpiece 3 in front of it along the sliding channel. The material conveyor moves, allowing the workpiece 3 to smoothly reach the clamping mechanism 15. At this time, the electric rotary rod 152 is rotated, causing the clamping block 151 to move. This causes the protrusion at one bottom edge of the clamping block 151 to engage with the corresponding notch 1272 at the top of the slide rail 127. The protrusion then abuts against the two edges of the workpiece 3 through the notch 1272, thus clamping and limiting its position. After positioning, the first servo motor 121 is driven, causing the tap 125 to move downwards towards the clamped workpiece 3. At the same time, the second servo motor 122 is started, driving two tapping taps 125 to tap the workpiece 3 simultaneously. When the tapping of the part is completed, the tapping mechanism is reset under the drive of the first servo motor 121. At the same time, the clamping mechanism 15 releases the tapped workpiece 13. Under the push of the workpiece 3 continuously entering the sliding channel and the drive of the unloading roller 16, the processed workpiece 3 is removed from the sliding channel, realizing automatic unloading. In specific operation, the last workpiece 3 to be processed needs to be loaded and unloaded with manual assistance.
