DETAILED DESCRIPTION

[0030] The technical scheme in the embodiments of the present invention will be explained clearly below in conjunction with the drawings in the embodiments of the present invention; it will be described completely. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figure 1-Figure 12A thread forming device for copper nut processing comprises a bracket 1, an automatic clamping seat 2 is installed in the bracket 1, the bracket 1 comprises a fixing frame 11 and a bottom plate 12 fixedly connected together, the automatic clamping seat 2 comprises a workbench 21, two fixing plates 22 are symmetrically fixedly connected between the outer surface of the workbench 21 and the inner surface of the fixing frame 11, a waste liquid discharge port 23 is opened at the center of the workbench 21, a guide pipe 231 facing the waste liquid discharge port 23 is fixedly connected to the bottom surface of the workbench 21, a plurality of equally spaced limiting grooves 24 are opened on the workbench 21, a sliding seat 241 is slidingly connected in the limiting groove 24, a clamping rod 242 is fixedly connected to the side surface of the sliding seat 241 close to the driving mechanism 3, and a plurality of first A mounting plate 243, a synchronous connecting ring 244 is slidably connected to the outer surface of the guide tube 231, and a plurality of second mounting plates 245 are fixedly connected to the outer surface of the synchronous connecting ring 244, a connecting rod 246 is installed between the first mounting plate 243 and the second mounting plate 245, and both ends of the connecting rod 246 are rotatably connected to the first mounting plate 243 and the second mounting plate 245 through a rotating shaft, wherein a first return spring 247 is installed in two limit grooves 24, and the first return spring 247 is fixedly connected between the limit groove 24 and the slide seat 241, an automatic ejection component is installed on the workbench 21, and an adjustment component is installed in the limit groove 24, and a feed pipe 26 is fixedly connected to the bottom side surface of the synchronous connecting ring 244, and the feed pipe 26 is slidably connected to the guide tube 231;

[0032] A driving mechanism 3 facing the automatic clamping seat 2 is installed on the top of the bracket 1, and the driving mechanism 3 includes an electric cylinder 31. The electric cylinder 31 is installed on the side surface of the top of the fixed frame 11 close to the workbench 21. A tapping machine 32 is installed on the output end of the electric cylinder 31, and a tap 33 is installed on the tapping machine 32. A baffle 34 is fixedly connected to the bottom surface of the tapping machine 32, and the inner surface of the baffle 34 is inclined at 45°. One side surface of the top of the clamping rod 242 matches the baffle 34. A waste liquid recovery mechanism 4 facing the automatic clamping seat 2 is installed on the bottom end of the bracket 1.

[0033] Since the fixed seat on the existing thread cutting machine is generally of fixed size, it can only be applied to a single type of copper nut, and needs to be fixed manually, and cannot be automatically fixed. In order to solve this problem, the present invention provides an automatic clamping seat 2 and a driving mechanism 3. In the automatic clamping seat 2, since the limiting groove 24 has a limiting effect on the slide 241, the slide 241 is limited to slide only in the limiting groove 24, and the guide tube 231 has a limiting effect on the synchronous connection ring 244, which limits the synchronous connection ring 244 to slide up and down only in the vertical direction. In addition, since the slide 241 and the synchronous connection ring 244 are connected by The first mounting plate 243, the second mounting plate 245 and the connecting rod 246 are rotatably connected, and the connecting rod 246 acts as a connecting rod between the slide 241 and the synchronous connecting ring 244. The synchronous connecting ring 244 and the connecting rod 246 connect the multiple slides 241 into a synchronously moving whole. Whenever a slide 241 moves along the limiting groove 24, the slide 241 will drive the synchronous connecting ring 244 to move in the vertical direction through the first mounting plate 243, the connecting rod 246 and the second mounting plate 245, and then drive other slides 241 to move synchronously through the movement of the synchronous connecting ring 244.

[0034] When fixing the copper nut before processing, first place the copper nut on the workbench 21, then start and control the electric cylinder 31 to extend, and the output end of the electric cylinder 31 drives the tapping machine 32, the tap 33 and the blocking cover 34 to move downward synchronously. In the process of the blocking cover 34 moving downward, the inclined inner surface of the blocking cover 34 will contact and squeeze the inclined surface of the clamping rod 242. Due to the limiting effect of the limiting groove 24 on the slide 241 and the clamping rod 242, as the blocking cover 34 moves downward, under the squeezing effect of the inner wall of the blocking cover 34, multiple clamping rods 242 drive the slide 241 to move synchronously toward the waste liquid discharge port 23 and approach each other until multiple clamping rods 242 are all held on the outer surface of the copper nut, and the blocking cover 34 moves downward. The lateral extrusion of the clamping rod 242 drives multiple clamping rods 242 to synchronously clamp the outer surface of the copper nut, thereby clamping and fixing the copper nut. Because the movement of multiple clamping rods 242 is synchronous, the clamping and fixing effect is good, and the position and angle of the copper nut can be automatically adjusted and corrected during the clamping and fixing process. Because the automatic clamping seat 2 can be driven by the downward movement of the driving mechanism 3 to realize automatic clamping and fixing of the copper nut, the operation is simple and easy to use. Because the clamping and fixing method is adopted, it can be suitable for clamping and fixing of various different types of nuts. After the copper nut is clamped and fixed, the tapping machine 32 can be controlled to drive the tap 33 to perform internal thread processing on the copper nut.

[0035] The automatic ejection assembly includes a through hole 25 formed on the workbench 21 , the through hole 25 is directly opposite to the synchronous connecting ring 244 , a slide rod 251 is slidably connected in the through hole 25 , and an ejection platform 252 is fixedly connected to one end of the slide rod 251 extending upward from the through hole 25 .

[0036] After the inner thread of the copper nut is processed, in order to facilitate the removal of the copper nut, the present invention is provided with an automatic ejection component. When placing the copper nut, the copper nut is placed on the ejection platform 252. In the process of clamping and fixing the copper nut, as the blocking cover 34 moves downward to squeeze the clamping rod 242 laterally, multiple clamping rods 242 move synchronously and approach each other. Under the action of the connecting rod 246, the synchronous connecting ring 244 moves downward. As the synchronous connecting ring 244 moves downward, the slide bar 251 slides down along the through hole 25, and the ejection platform 252 and the copper nut also move downward with the sliding of the slide bar 251, and finally fall onto the workbench 21, and then are synchronously clamped and fixed by multiple clamping rods 242. In the process of the clamping rods 242 moving synchronously and approaching each other, the first return spring 24 7 is squeezed to accumulate elastic potential energy. Therefore, after the internal thread processing of the copper nut is completed, when the electric cylinder 31 is controlled to drive the tapping machine 32, the tap 33 and the baffle 34 to move upward, the elastic potential energy accumulated in the first return spring 247 is released, thereby driving the multiple clamping rods 242 to move away from each other synchronously through the slide 241, releasing the clamping fixation of the copper nut. Then, as the clamping rods 242 move away from each other synchronously, the clamping rod 242 drives the synchronous connecting ring 244 to move upward through the slide 241, the first mounting plate 243, the connecting rod 246 and the second mounting plate 245. During the upward movement of the synchronous connecting ring 244, the synchronous connecting ring 244 first contacts the slide bar 251, and then pushes the slide bar 251 and the ejection platform 252 upward to realize the automatic ejection of the copper nut for removal.

[0037] A drainage pipe 253 is fixedly connected to the inner surface of the ejector platform 252, and the drainage pipe 253 is arranged to converge from top to bottom. With the help of the ejector platform 252 and the drainage pipe 253, the coolant mixed with metal scraps generated during the internal thread processing of the copper nut is guided to flow into the waste liquid discharge port 23 and the guide pipe 231, so as to facilitate unified recycling and avoid waste.

[0038] The adjustment component includes a threaded hole 248 formed on an inner surface of the limiting groove 24 away from the waste liquid discharge port 23 , a threaded rod 249 is threadedly connected to the threaded hole 248 , and a rotary handle is fixedly connected to one end of the threaded rod 249 away from the workbench 21 .

[0039] When it is necessary to adjust the final ejection height of the copper nut, the handle can be rotated to drive the threaded rod 249 to rotate. With the help of the threaded connection between the threaded rod 249 and the threaded hole 248, the length of the threaded rod 249 extending into the limit groove 24 can be adjusted. The threaded rod 249 extending into the limit groove 24 will limit the displacement stroke of the slide 241 in the limit groove 24, and then limit the lifting stroke of the synchronous connecting ring 244, thereby realizing the control and adjustment of the ejection height.

[0040] The waste liquid recovery mechanism 4 includes a recovery box 41, which is fixedly connected to a side surface of the base plate 12 close to the workbench 21. A filter screen 42 is slidably connected inside the recovery box 41, and a second return spring 44 is fixedly connected between an inner surface of the recovery box 41 and the filter screen 42.

[0041] The filter screen 42 is inclined, and the bottom surface of the feed pipe 26 is inclined to match the filter screen 42 . A waste chip outlet 43 is opened on one side surface of the recovery box 41 , and the waste chip outlet 43 is located below the filter screen 42 .

[0042] In the process of clamping and fixing the copper nut, the clamping rod 242 will drive the synchronous connecting ring 244 to move downward through the slide seat 241, the first mounting plate 243, the connecting rod 246 and the second mounting plate 245, and the synchronous connecting ring 244 will drive the feeding tube 26 to move downward, so that the feeding tube 26 is pressed tightly on the filter screen 42. Subsequently, in the process of machining the internal thread of the copper nut, as the coolant is injected, the coolant mixed with copper chips enters the guide tube 231 along the drainage pipe 253, and then falls on the filter screen 42 along the feeding tube 26. The copper chips are intercepted by the filter screen 42 and remain on the filter screen 42. The coolant enters the recovery box 41 through the filter screen 42, so as to separate the copper chips and the coolant and collect the coolant uniformly. After the machining is completed, the injection of coolant is stopped. Cooling liquid, when taking out the copper nut, the clamping rod 242 will drive the synchronous connecting ring 244 to move up through the sliding seat 241, the first mounting plate 243, the connecting rod 246 and the second mounting plate 245, and the synchronous connecting ring 244 will then drive the feeding tube 26 to move up, so that the feeding tube 26 leaves the filter screen 42, and the copper chips trapped on the filter screen 42 slide along the inclined surface of the filter screen 42 to the lowest point of the filter screen 42. In the next process of clamping and fixing the copper nut, the filter screen 42 can be pressed down by the feeding tube 26 to move the filter screen 42 downward, and the lowest point of the filter screen 42 is connected to the waste chip discharge port 43, so that the previously retained copper chips are discharged through the waste chip discharge port 43, and waste is avoided by extending the time for the coolant to drain out of the copper chips.

[0043] In the present invention, when the copper nut is fixed before processing, the copper nut is first placed on the ejection platform 252, and then the electric cylinder 31 is started and controlled to extend, and the output end of the electric cylinder 31 drives the tapping machine 32, the tap 33 and the blocking cover 34 to move downward synchronously. In the process of the blocking cover 34 moving downward, the inclined inner surface of the blocking cover 34 will contact and squeeze the inclined surface of the clamping rod 242. Due to the limiting effect of the limiting groove 24 on the sliding seat 241 and the clamping rod 242, as the blocking cover 34 moves downward, under the squeezing effect of the inner wall of the blocking cover 34, the multiple clamping rods 242 drive the sliding seat 241 and the clamping rod 242 to move downward. The seats 241 synchronously move toward the direction of the waste liquid discharge port 23 and approach each other until the multiple clamping rods 242 are all held on the outer surface of the copper nut. With the help of the downward movement of the blocking cover 34 to lateral squeeze the clamping rods 242, the multiple clamping rods 242 are driven to synchronously clamp the outer surface of the copper nut to achieve clamping and fixing of the copper nut. In the process of the clamping rods 242 synchronously moving and approaching each other, the first return spring 247 is squeezed to accumulate elastic potential energy. After the copper nut is clamped and fixed, the tapping machine 32 can be controlled to drive the tap 33 to perform internal thread processing on the copper nut.

[0044] After the internal thread processing of the copper nut is completed, when the electric cylinder 31 is controlled to drive the tapping machine 32, the tap 33 and the baffle 34 to move upward, the elastic potential energy accumulated in the first return spring 247 is released, thereby driving the multiple clamping rods 242 to move away from each other synchronously through the slide 241, releasing the clamping fixation of the copper nut, and then as the clamping rods 242 move away from each other synchronously, the clamping rod 242 drives the synchronous connecting ring 244 to move upward through the slide 241, the first mounting plate 243, the connecting rod 246 and the second mounting plate 245. During the upward movement of the synchronous connecting ring 244, the synchronous connecting ring 244 first contacts the slide bar 251, and then pushes the slide bar 251 and the ejection platform 252 upward to realize the automatic ejection of the copper nut for removal;

[0045] In the process of clamping and fixing the copper nut, the clamping rod 242 will drive the synchronous connecting ring 244 to move downward through the slide seat 241, the first mounting plate 243, the connecting rod 246 and the second mounting plate 245, and the synchronous connecting ring 244 will drive the feeding tube 26 to move downward, so that the feeding tube 26 is pressed against the filter screen 42. Subsequently, in the process of machining the internal thread of the copper nut, as the coolant is injected, the coolant mixed with copper chips enters the guide tube 231 along the drainage pipe 253, and then falls onto the filter screen 42 along the feeding tube 26. The copper chips are intercepted by the filter screen 42 and remain on the filter screen 42. The coolant enters the recovery box 41 through the filter screen 42, so as to realize the separation of copper chips and coolant and the unified collection of coolant. After the processing is completed, stop injecting coolant. When taking out the copper nut, the clamping rod 242 will drive the synchronous connecting ring 244 to move upward through the slide seat 241, the first mounting plate 243, the connecting rod 246 and the second mounting plate 245. The synchronous connecting ring 244 then drives the discharge pipe 26 to move upward, so that the discharge pipe 26 leaves the filter screen 42, and the copper chips trapped on the filter screen 42 slide along the inclined surface of the filter screen 42 to the lowest point of the filter screen 42. In the next process of clamping and fixing the copper nut, the filter screen 42 can be pressed down by the discharge pipe 26 to move the filter screen 42 downward, and the lowest point of the filter screen 42 is connected to the waste chip discharge port 43, so that the previously retained copper chips are discharged through the waste chip discharge port 43.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
