Description

Technical Field

[0001] The invention relates to the technical field of thread rolling machines, in particular to a fully automatic high-precision thread rolling machine. Background Art

[0002] The thread rolling machine is a multifunctional, warm spinning forming machine tool. The thread rolling machine can perform high-precision cold or warm rolling processing on aviation threads or precision screws with high precision requirements (high precision of thread and size) in cold or warm state within its rolling force range.

[0003] The thread rolling machine is a machine that places two main shaft assemblies close to each other and uses two rolling wheels to roll the product in the middle. The main shaft assembly in the thread rolling machine is composed of a main shaft, a reduction gearbox, and a drive motor. In the existing thread rolling machine, the main shaft, reduction gearbox, and drive motor are connected end to end in sequence, with the tail end of the main shaft connected to the output end of the reduction gearbox, and the input end of the reduction gearbox connected to the output end of the drive motor. This will cause the adjustment of the end face flushness of the thread rolling wheel (spindle axial position adjustment) to be complex and unstable. The reference changes after each adjustment, and the repeatability is poor. Secondly, the overall structure is very long, and the weight of the reduction gearbox and the drive motor is heavy, which will cause the center of gravity of the overall structure of the main shaft to move backward, and its center of gravity will be biased toward one end of the reduction gearbox and the drive motor. In this way, when the main shaft slides with the slide, the center of gravity of the slide will be away from the top of the guide rail, and the slide will be relatively If the guide rail is tilted to one side, it will affect the tightness of the connection between the slide and the guide rail. At the same time, the center of gravity shifts backward, causing the spindle bearing to wear more severely, which will have the following consequences: First, it will affect the positioning of the spindle assembly, the rapid wear of the spindle bearing, and the repeated positioning accuracy of the axial position (flushness of the end face of the rolling wheel) between the two spindle assemblies will deteriorate, which will have a serious impact on the processing accuracy of the product, especially the aviation thread processing quality with extremely high requirements for thread accuracy (thread error requirement is less than 1 wire); second, it will increase the overturning torque value between the slide and the guide rail and cause uneven friction of the slider, resulting in rapid wear of the guide rail and generation of gaps, thereby affecting the processing accuracy of aviation threads and high-precision screws with high precision requirements. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned problems. A fully automatic high-precision thread rolling machine is designed to solve the problems that the center of gravity of the existing spindle assembly is far back, causing the slide to tilt to one side relative to the guide rail, affecting the service life of the guide rail and the axial repeat positioning accuracy of the spindle.

DETAILED DESCRIPTION

[0048] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] like Figure 1-Figure 5 As shown, a fully automatic high-precision thread rolling machine mainly includes a lower body 1, an upper body 2, a slide 3, a first support adjustment plate 5, a second support adjustment plate 6, a spindle assembly, an automatic feeding and heating device, a product positioning device 24, an electric control cabinet 19, a control and display module 20, etc., wherein the upper body 2 is installed and fixed on the lower body 1. Since a mounting groove is provided in the middle of the upper part of the upper body 2, the shape of the entire upper body 2 is U-shaped, or it can be said to be "concave". The upper body 2 is cast in one piece, so its overall strength is very high and it will not be easily deformed.

[0050] A slide rail 31 is arranged on the upper body 2, and the bottom of the slide seat 3 is horizontally slidably connected to the slide rail 31. The above-mentioned first support adjustment plate 5 is rotatably connected to the inner wall of the upper body 2, and the second support adjustment plate 6 is arranged on the slide seat 3 on the side close to the first support adjustment plate 5, and is vertically rotatably connected to the slide seat 3. Two main shaft assemblies are arranged on the first support adjustment plate 5 and the second support adjustment plate 6 respectively. The product positioning device 24 is located in the middle of the first support adjustment plate 5 and the second support adjustment plate 6. The distance between the two main shaft assemblies can be adjusted by moving the slide seat 3, and the product on the product positioning device 24 can be thread rolled.

[0051] like Fig.10 As shown, the spindle assembly is mainly composed of a reduction box 36, a servo drive motor 37, a spindle 23, etc. A thread rolling wheel 38 is arranged on the spindle 23. The overall shape of the first support adjustment plate 5 and the second support adjustment plate 6 is "convex". The front bearing support seat 26 and the axial adjustment seat 34 are respectively arranged at the front and rear ends of the first support adjustment plate 5 and the second support adjustment plate 6. The spindle 23 passes through the support adjustment plate, and its two ends are rotatably connected with the front bearing support seat 26 and the axial adjustment seat 34 respectively. The reduction box 36 is arranged between the support adjustment plate and the axial adjustment seat 34. A hollow shaft is arranged at the output end of the reduction box 36. One end of the spindle 23 passes through the support adjustment plate and the hollow shaft in turn and is rotatably connected with the axial adjustment seat 34. The spindle 23 is clamped with the hollow shaft through a key and a keyway. The top end of the reduction box 36 is the input end, and the input end is perpendicular to the output end. The servo drive motor 37 is drivingly connected to the input end of the reduction box 36.

[0052] refer to Fig.10A bearing cover 39 and an adjustment seat end cover 40 are respectively provided at the front and rear ends of the main shaft 23. The bearing cover 39 is installed on the front bearing support seat 26, and the adjustment seat end cover 40 is installed on the axial adjustment seat 34, which plays a sealing role to prevent external dust from entering the bearings on the front bearing support seat 26 and the axial adjustment seat 34. A bearing cover 39 is also provided at the connection between the main shaft 23 and the first support adjustment plate 5 and the second support adjustment plate 6, both of which play a protective role. An axial adjustment screw 35 is also threadedly connected to the axial adjustment seat 34, and the axial adjustment screw 35 is abutted against the rear end of the main shaft 23. The axial position of the main shaft 23 can be adjusted by rotating the axial adjustment screw 35, and the main shaft 23 can be prevented from sliding in the axial direction.

[0053] Compared with the conventional motor and reduction box 36 drive structure, the center of gravity of the spindle assembly is more biased towards the center. The conventional method is to connect the spindle 23 with the reduction box 36, and the reduction box 36 is connected to the motor on one side, so that the spindle 23, the reduction box 36 and the motor are in a straight line. Due to the heavy weight of the motor and the reduction box 36, this design has two defects. First, the center of gravity of the entire structure is relatively far back, and the center of gravity is at the end where the motor is located, which will cause a great burden on the spindle 23. Second, due to the relatively far center of gravity, it will cause the slide 3 and the slide The connection between the rails 31 creates a burden, and the slide 3 tends to tilt to one side when sliding, which will increase the wear of the slide rail 31 and affect the service life of the slide rail 31. With our design, the overall length of the spindle assembly is shortened, the rigidity of the spindle and its support seat is enhanced, and the spindle bearing group is effectively protected. At the same time, the center of gravity of the spindle assembly will be biased toward the middle, and the center of gravity will be close to the slide rail 31, so that the slide 3 will reduce the burden on the slide rail 31 when sliding, thereby improving the service life of the slide rail 31 and the consistency of machining accuracy.

[0054] like Figure 5 and Figure 8As shown, in order to facilitate the adjustment of the taper between the two spindle assemblies, a rotating shaft 27 and a taper adjustment assembly 7 are arranged between the first support adjustment plate 5 and the upper body 2. The rotating shaft 27 is semi-cylindrical or cylindrical, wherein the taper adjustment assembly 7 is mainly composed of an adjusting screw seat 701, a wedge-shaped body 702, a taper adjustment screw 703, an adjusting nut 704, etc., wherein the shape of the wedge-shaped body 702 is also semi-cylindrical, thick at the top and narrow at the bottom, and two grooves respectively matching the rotating shaft 27 and the wedge-shaped body 702 are provided on the inner wall of the upper body 2, the rotating shaft 27 is located in the groove, and the first support adjustment plate is horizontally rotatably connected to the upper body 2 through the rotating shaft 27, and the above-mentioned adjusting screw seat 701 is fixed at the top of another groove, and the wedge-shaped body 702 is located at the top of the other groove. In the groove, the wedge body 702 is provided with a slot, the lower end of the taper adjustment screw 703 is located in the slot and can rotate relative to the wedge body 702, the upper end of the taper adjustment screw 703 passes through the adjustment screw seat 701 and is connected with the adjustment nut 704, and the taper adjustment screw 703 and the adjustment screw seat 701 are also threadedly connected. By rotating the taper adjustment screw 703, the wedge body 702 can be controlled to move up and down along the groove. In the process of moving up and down, the wedge body 702 will squeeze the first support adjustment plate 5, and the first support adjustment plate 5 will rotate through the rotating shaft 27, so that the parallelism between the first support adjustment plate 5 and the second support adjustment plate 6 (it can also be said to be the angle or taper between the first support adjustment plate 5 and the second support adjustment plate 6) can be adjusted.

[0055] like Figure 7 As shown, a plurality of material reduction holes 201 are provided at one end of the upper fuselage 2 close to the first support adjustment plate 5, so as to reduce its own weight without affecting the structural strength of the upper fuselage 2. A fastening bolt 30 is provided in each material reduction hole 201. When the taper of the first support adjustment plate 5 is adjusted, the fastening bolt 30 is respectively connected to the rotating shaft 27 and the wedge body 702 for fixing the first support adjustment plate 5.

[0056] like Figure 5 and Figure 6As shown, the second support adjustment plate 6 is rotatably connected to the slide 3 through a rotating shaft, and two inclination adjustment components 8 corresponding to the front and rear ends of the second support adjustment plate 6 are arranged on the slide 3, respectively. The inclination adjustment component 8 is mainly composed of a fixing member 801, an inclination adjustment screw 803, a fastening nut 802, etc., wherein the fixing member 801 is installed and fixed on the slide 3, and the fastening nut 802 is sleeved on the inclination adjustment screw 803. The lower end of the inclination adjustment screw 803 passes through the fixing member 801 and abuts against the upper surface of the second support adjustment plate 6. In this way, when the inclination of the spindle assembly needs to be adjusted, it is only necessary to rotate the front and rear inclination adjustment screws 803 to make the second support adjustment plate 6 rotate vertically along the slide 3. At the same time, in order to facilitate the measurement of the inclination, a dial indicator 28 is also arranged on the slide 3, and the measuring rod of the dial indicator 28 abuts against the upper surface of the second support adjustment plate 6. By reading the value of the dial indicator 28, the inclination of the second support adjustment plate 6 can be obtained.

[0057] like Figure 7 As shown, a plurality of elongated holes 301 corresponding to the front and rear ends of the second support adjustment plate 6 are provided on the side wall of the slide seat 3. The shape of the elongated holes 301 is an arc. The distribution trajectory of the plurality of elongated holes 301 matches the rotation trajectory of the front and rear ends of the second support adjustment plate 6. After adjusting the inclination of the second support adjustment plate 6, it is only necessary to lock the second support adjustment plate 6 with bolts to prevent the second support adjustment plate 6 from rotating. When the inclination needs to be adjusted, the bolts need to be removed first.

[0058] like Figure 4 , Figure 5 , Fig.10 , Fig.11 As shown, a rotating body 42 fixing frame 41 and a rotating body 42 are provided at the front ends of the first support adjustment plate 5 and the second support adjustment plate 6. The rotating body 42 and the rotating body 42 fixing frame 41 are horizontally rotatably connected. A T-shaped slot 421 is provided on one side of the rotating body 42 and the first support adjustment plate 5 and the second support adjustment plate 6. The above-mentioned front bearing support seat 26 is horizontally slidably connected to the T-shaped slot 421. Initially, the T-shaped slot 421 on the rotating body 42 is docked with the T-shaped slot 421 on the support adjustment plate. When it is necessary to replace the thread rolling wheel 38 on the main shaft 23, it is only necessary to slide the front bearing support seat 26 along the T-shaped slot 421 from the support adjustment plate to the rotating body 42, and then rotate the rotating body 42 to drive the front bearing support seat 26 to rotate together. In this way, the front bearing support seat 26 can be removed from the main shaft 23, which is convenient and quick.

[0059] If the front bearing support seat 26 needs to be assembled, the front bearing support seat 26 is slid onto the support adjustment plate again, and then the front bearing support seat 26 and the support adjustment plate are locked with bolts, so that the front bearing support seat 26 will not move at will.

[0060] In the prior art, when the thread rolling wheel 38 needs to be replaced, the front bearing support seat 26 is usually directly disassembled and placed on the ground or a table. After the replacement is completed, the front bearing support seat 26 is reassembled. This practice may contaminate the surface of the front bearing support seat 26. Dirt may adhere to the surface of the front bearing support seat 26 on the ground or the table, affecting the subsequent processing of the thread rolling wheel 38. However, if our method is used, there is no need to worry about this situation.

[0061] like Figure 12-14 As shown, the above-mentioned product positioning device 24 is located between the first support adjustment plate 5 and the second support adjustment plate 6 (i.e., two spindle assemblies), and is slidably connected to the slide rail 31 on the upper fuselage 2. The product positioning device 24 can position the product to be processed and automatically unload the product. The product positioning device 24 is mainly composed of a base 241, a rolling support plate seat 242, a mounting support 243, a screw drive assembly, a cylinder fixing frame 246, a bracket 245, a support plate 244, a downward pressure cylinder 247, a pressure plate 248, a push rod 256, a limit block 254, a push assembly, etc., wherein the bottom of the base 241 is horizontally slidably connected to the slide rail 31, and the rolling support plate seat 242 is fixedly mounted. It is fixed on the base 241, and a slide groove is arranged on the rolling support plate seat 242. The bottom of the mounting support 243 is slidably connected to the slide groove. The cylinder fixing frame 246, the bracket 245 and the support plate 244 are all installed and fixed on the mounting support 243. The three are on the same connecting line. A row of fixing holes is arranged on the top of the mounting support 243, and the lower ends of the cylinder fixing frame 246, the bracket 245 and the support plate 244 are all provided with a number of oblong holes. The spacing between the cylinder fixing frame 246, the bracket 245 and the support plate 244 can be adjusted through the fixing holes, and the upper and lower relative heights of the cylinder fixing frame 246, the bracket 245 and the support plate 244 can be adjusted through the oblong holes.

[0062] The downward pressure cylinder 247 is vertically installed at the front end of the cylinder fixing frame 246 and is located directly above the support plate 244. The pressing plate 248 is connected to the output end of the downward pressure cylinder 247. The downward pressure cylinder 247 drives the product to be processed to be pressed against the support plate 244. The overall shape of the bracket 245 is U-shaped. The push rod 256 is horizontally inserted into the bracket 245, one end of which passes through the U-shaped groove on the bracket 245, and the other end extends to the top of the top surface of the support plate 244. The limit block 254 can push the push rod 256 in the U-shaped groove of the bracket 245. 56 slides, according to the different specifications of the products to be processed, the length of the push rod 256 extending to the support plate 244 can be adjusted, and the limit block 254 is used to limit the sliding distance of the push rod 256. When the products to be processed are positioned, it is only necessary to abut the end of the products to be processed against the front end of the push rod 256, and then pre-tighten the products to be processed through the pressure plate 248, and then the two thread rolling wheels 38 can approach the products to be processed to clamp them, and then the pressure plate 248 will release the products to be processed, and the two thread rolling wheels 38 can process them.

[0063] like Fig.14 As shown, the above-mentioned screw drive assembly is composed of a tension seat 251, a screw, a locking piece 253, a knob 252, etc. One end of the screw passes through the tension seat 251 and is driven and connected to the bottom of the mounting support 243, and the other end is connected to the knob 252, and the locking piece 253 is threadedly connected to the tension seat 251 to adjust the tightness of the tension seat 251; when the position of the mounting support 243 needs to be adjusted, it is only necessary to rotate the knob 252 to drive the screw to rotate, thereby driving the mounting support 243 to slide along the rolling support plate seat 242. After adjustment, tighten the locking piece 253 to lock the screw to prevent the screw from rotating. In this way, the length of the rolled thread on the product to be processed can be adjusted.

[0064] refer to Fig.15 The processed products will be pushed down from the support plate 244 through the pushing assembly, which is composed of a pushing cylinder 249 horizontally arranged on one side of the cylinder fixing frame 246 and a pushing plate 250 connected to the output end of the pushing cylinder 249. A U-shaped avoidance groove 2501 is arranged at the bottom of the pushing plate 250. When pushing the material, the push rod 256 will be accommodated in the avoidance groove 2501 to avoid interference between the push rod 256 and the pushing plate 250.

[0065] like Fig.12 As shown, a blanking slide 44 is also provided on one side of the support plate 244, and a receiving trough 45 is provided at the discharge port of the blanking slide 44. The processed products will be pushed by the pushing cylinder 249 to push the stripping plate horizontally, and the products will be pushed onto the blanking slide 44, and the products will fall into the receiving trough 45 along the blanking slide 44.

[0066] When processing the product, the slide 3 will be moved to make the two spindle assemblies close to the product positioning device 24. In order to ensure the accuracy of product processing, it is necessary to ensure that the product positioning device 24 is always in the middle of the two spindle assemblies. A connecting rod centering mechanism 22 is also provided at the bottom of the product positioning device 24. Every time the slide 3 moves a certain distance, the product positioning device 24 moves half of the distance. The moving distance of the two is 2:1.

[0067] like Fig.17 As shown, the connecting rod centering mechanism 22 is mainly composed of a first connecting rod 223, a second connecting rod 224, a first connecting member 221, a second connecting member 222, etc., a limiting member 46 is provided at the middle of the bottom of the base 241 in the product positioning device 24, and a limiting groove is provided on the limiting member 46, the ends of the first connecting rod 223 and the second connecting rod 224 are hinged through a follower shaft 225, the other end of the first connecting rod 223 is hinged to the first connecting member 221, the other end of the second connecting rod 224 is hinged to the second connecting member 222, and the first connecting member 221 and the second connecting member 224 are hinged to each other. The two connecting members 222 are respectively installed and fixed on the inner wall of the upper body 2 and the outer wall of the slide 3. The upper end of the follower shaft 225 is embedded in the limiting groove on the limiting member 46. The follower shaft 225 can slide along the limiting groove. Blocking plates 47 are provided at both ends of the limiting groove to prevent the follower shaft 225 from sliding out of the limiting groove. When the slide 3 slides, the product positioning device 24 will be driven to slide together through the connecting rod and the follower shaft 225. The moving distance of the product positioning device 24 is half of the moving distance of the slide 3. In this way, it can be ensured that the product positioning device 24 is always in the middle of the two main shaft assemblies.

[0068] refer to Fig.14 In order to drive the slide 3 to move, a support frame 49, a reduction box 36 and a servo drive motor 37 are also provided at one end of the upper body 2 close to the slide 3, wherein the support frame 49 is fixedly mounted on the end of the upper body 2, and the reduction box 36 is fixedly mounted on the support frame 49. A hollow shaft is also provided at the output end of the reduction box 36, and a screw rod is inserted in the hollow shaft. One end of the screw rod is clamped with the hollow shaft through the cooperation of a key and a keyway, and the other end passes through the upper body 2 and is driven and connected to the slide 3. The servo drive motor 37 is driven and connected to the output end on one side of the reduction box 36, which can save installation space. The servo drive motor 37 drives the output shaft of the reduction box 36 to rotate, driving the screw rod to rotate, thereby driving the slide 3 to press the upper body 2 to slide horizontally, controlling the two spindle assemblies to approach each other, and processing the product to be processed on the product positioning device 24.

[0069] refer to Figure 5 and Fig. 9, because the two thread rolling wheels 38 will give an oblique upward force to the two ends of the upper fuselage 2 when rotating, so that the upper fuselage 2 will produce a slight deformation at both ends, and the deformation amount generally ranges from a few threads to more than twenty threads. For this reason, we set a crossbeam 9 at the upper opening of the upper fuselage 2, and set two card slots at the two ends of the bottom of the crossbeam 9, which are named as the first card slot 91 and the second card slot 92 for the convenience of description. A card block 25 is set at each end of the top of the upper fuselage 2, and the card block 25 is fixedly connected to the upper fuselage 2 by bolts. The two card blocks 25 are respectively matched with the first card slot 91 and the second card slot 92, wherein the width of the first card slot 91 is consistent with the width of the card block 25, and the width of the second card slot 92 is greater than the width of the card block 25, so If the upper fuselage 2 is deformed, the distance between the two clamping blocks 25 will become larger, and the cross beam 9 can also be clamped with the two clamping blocks 25. At the same time, two threaded holes connected to the second clamping groove 92 are arranged on the end face of the cross beam 9 close to one end of the second clamping groove 92. After the cross beam 9 is assembled on the upper fuselage 2, the whole will form a "U"-shaped structure, and a tightening bolt is arranged in the threaded hole, and the tightening bolt is in abutment with the clamping block 25 to realize a closed bearing structure with adjustable preload in the rolling area. By tightening the tightening bolt, the two ends of the upper fuselage 2 will be subjected to a tensile force under the action of the cross beam 9, pulling the two ends of the upper fuselage 2 toward the center, so that the two ends of the upper fuselage 2 can be prevented from expanding and deforming outward, and the preload can be adjusted by adjusting the tightness of the tightening bolt.

[0070] refer to Figure 6 and Figure 7 When the thread rolling machine is working, the slide 3 will also be subjected to an oblique upward force, which will cause the slide 3 to have an upward tendency. In this way, the connection between the slide 3 and the slide rail 31 at the bottom is not tight enough, and the wear of the slide rail 31 will increase, affecting its service life. Therefore, we also set a slide rail 31 on the top of the slide 3, and an upper slider 32 is slidably connected to the slide rail 31. There is an oblique slot between the bottom surface of the crossbeam 9 and the upper surface of the upper slider 32. The oblique slot is wide outside and narrow inside. A wedge plate 33 is set in the oblique slot. By knocking the wedge plate 33 The wedge plate 33 is inserted into the inclined slot until there is no gap between the upper slider 32, the slide rail 31 and the wedge plate 33. The wedge plate 33 can suppress the upward tilting tendency and micro-displacement of the slide seat 3 when the thread rolling machine is working, thereby ensuring that the slide seat 3 does not tilt upward. This can improve the service life of the slide rail 31 and the processing accuracy of the product. The close fit between the wedge plate 33, the crossbeam 9 and the upper slider 32 can prevent the slide seat 3 from being displaced upward when the slide rail 31 is subjected to the overturning torque.

[0071] refer to Figure 4A water supply pipe 29 is also provided on the cross beam 9, and the outlet end of the water supply pipe 29 faces the product to be processed between the two thread rolling wheels 38. During processing, the water supply pipe 29 will spray water to the product to be processed to cool it down and prevent it from being deformed due to excessive temperature. A cooling system 21 is provided on the lower fuselage 1, and the cooling system 21 is connected to the water supply pipe 29 to provide cooling water to the water supply pipe 29.

[0072] like Figure 1 , Fig.18 As shown, in order to prevent the automatic feeding and heating device from hindering the workers' work when replacing the thread rolling wheel 38, the automatic feeding and heating device here can be rotated and shifted. The automatic feeding and heating device is mainly composed of a rotating seat 13, a vibrating feeding mechanism 14, a feeding robot 17, a dividing mechanism 16, a heating mechanism 15, etc., wherein one end of the rotating seat 13 is horizontally rotatably connected to the lower body 1 through a rotating shaft, and the other end is connected to the upper body 2 through a connecting component 43, and the connecting component 43 is detachably connected to the upper body 2, and the vibrating feeding mechanism 14, the feeding robot 17, the dividing mechanism 16 and the heating mechanism 15 are all installed and fixed on the rotating seat 13, and rotate with the rotating seat 13.

[0073] like Fig.18 As shown, the vibration feeding mechanism 14 is mainly composed of two parts: a vibration disk assembly 141 and a direct vibration assembly 142. The bottoms of the vibration disk assembly 141 and the direct vibration assembly 142 are fixed to the base 241 by bolts. The inlet of the direct vibration assembly 142 is connected to the outlet of the vibration disk assembly 141. The direct vibration assembly 142 and the dividing mechanism 16 are vertically distributed. The product to be processed is transferred from the vibration disk assembly 141 to the direct vibration assembly 142, and then the direct vibration assembly 142 transfers the product to be processed to the tail end, waiting for the dividing mechanism 16 to transfer and divide the material.

[0074] refer to Fig. 20 and Fig. 22The material distribution mechanism 16 is mainly composed of a stand 161, a material distribution cylinder 162, a slide plate 163, a mounting plate 164, a material distribution plate 165, etc., wherein the material distribution cylinder 162 is horizontally mounted and fixed on one side of the stand 161, and the slide plate 163 is horizontally slidably connected to one side of the material distribution cylinder 162, and the output end of the material distribution cylinder 162 is connected to the slide plate 163, which can drive the slide plate 163 to slide horizontally; the mounting plate 164 is mounted and fixed on one side of the slide plate 163, and the material distribution plate 165 is mounted and fixed on the side of the mounting plate 164, A stopper 48 matching the transfer direction of the dividing plate 165 is provided at the tail end of the direct vibration component 142, and a transfer groove 1651 for transferring a single product is provided on the side of the dividing plate 165. The stopper 48 is used to prevent the workpiece from separating from the transfer groove 1651 on the dividing plate 165 when the workpiece moves with the dividing plate 165. The dividing cylinder 162 drives the dividing plate 165 to move horizontally, and the dividing plate 165 transfers the product to be processed to the designated position through the transfer groove 1651, waiting for the heating mechanism 15 to heat it.

[0075] On the left and right sides of the stand 161, there are also two through-shooting sensors 166, which are respectively facing the two ends of the dividing plate 165, and are used to detect the presence of products to be processed on the dividing plate 165. If there are no products to be processed on the dividing plate 165, the transfer slot 1651 on the dividing plate 165 will move to the position of the direct vibration component 142 for loading.

[0076] like Fig.21 As shown, the heating mechanism 15 is arranged on one side of the material distribution mechanism 16, and the material distribution mechanism 16 and the heating mechanism 15 are both located between the vibration feeding mechanism 14 and the feeding robot 17. The heating mechanism 15 mainly includes a first mounting seat 151, a lifting cylinder 152, a second mounting seat 153, a heater 154 and other components, wherein the lifting cylinder 152 is vertically arranged on one side of the first mounting seat 151, the second mounting seat 153 is slidably connected to the side of the lifting cylinder 152 up and down, and the output end of the lifting cylinder 152 is fixedly connected to the second mounting seat 153, and the heater 154 is fixedly installed on the second mounting seat 153. A coil 155 is provided on the heater 154, and the coil 155 has a heating hole for accommodating the product to be processed. The lifting cylinder 152 can drive the coil 155 to move up and down. When the dividing plate 165 transfers the product to be processed to the top of the coil 155, the lifting cylinder 152 can drive the coil 155 to lift upward, so that the product to be processed can be inserted into the heating hole of the coil 155. The heater 154 energizes the coil 155 to increase the temperature, and uses the coil 155 to heat the product to be processed. After heating, the plasticity of the product will be improved, so that it can be rolled into shape, and the service life of the thread rolling wheel 38 can also be improved.

[0077] refer to Fig.19A suction component 171 is provided on the loading robot 17. The loading robot 17 can use the suction component 171 to suck the heated product to be processed on the dividing plate 165 and transfer it to the support plate 244 in the product positioning device 24. After the product positioning device 24 positions it, the two thread rolling wheels 38 will roll it.

[0078] When replacing the thread rolling wheel 38, the worker only needs to separate the connecting assembly 43 from the upper body 2, and then rotate the rotating seat 13 to move the automatic feeding heating device away. Fig.19 As shown, the connecting assembly 43 is mainly composed of an inclined rod 431, a first fixing member 432 and a second fixing member 433, wherein both ends of the inclined rod 431 are provided with oblong holes, one end of the inclined rod 431 is connected to the rotating seat 13 by bolts, and the other end is connected to the upper fuselage 2 by bolts, and the first fixing member 432 is fixedly installed on the end of the rotating seat 13, and the second fixing member 433 is installed and fixed at the corresponding position of the upper fuselage 2, and a plurality of bolt holes are provided on the first fixing member 432 and the second fixing member 433, and the first fixing member 432 is overlapped on the second fixing member 433 and fixedly connected by bolts.

[0079] refer to Fig.23 and Fig.24 In order to ensure that the first fixing member 432 and the second fixing member 433 do not slide up and down, an inclined surface 4331 is provided on the contact surface between the second fixing member 433 and the first fixing member 432, and a lap joint 4321 matching with the second fixing member 433 is provided at the bottom of the first fixing member 432. When installing, the first fixing member 432 will slide along the inclined surface 4331 of the second fixing member 433, and one end of the second fixing member 433 will overlap with the lap joint 4321 at the bottom of the first fixing member 432, so that the first fixing member 432 and the second fixing member 433 can be installed. The two fixing members 433 are pressed against each other to position the upper and lower positions of the first fixing member 432 and the second fixing member 433 to prevent a gap from being left between the first fixing member 432 and the second fixing member 433, and then the first fixing member 432 and the second fixing member 433 are fixed with bolts. The oblong hole on the diagonal rod 431 can ensure that the diagonal rod 431 can leave a moving displacement gap in the vertical direction so that the diagonal rod 431 can be better connected to the upper fuselage 2. After the first fixing member 432 and the second fixing member 433 are positioned up and down, the rotating seat 13 can be prevented from moving up and down.

[0080] like Fig.19As shown, a handle is also provided on one side of the rotating seat 13. When it is necessary to move, it is only necessary to remove the bolts at the connection between the first fixing member 432 and the second fixing member 433, and then remove the bolts between the inclined rod 431 and the upper fuselage 2. The handle can be manually held and pulled outward to drive the automatic feeding and heating device to rotate and move it away from the working position so that subsequent workers can replace the thread rolling wheel 38.

[0081] like Figure 1 As shown, a connecting plate 10 is vertically arranged on one side of the top of the cross beam 9, and a front cover shell 11 and a rear cover shell 12 are respectively arranged on the front and rear sides of the upper fuselage 2, the front cover shell 11 is hinged to the connecting plate 10, and the rear cover shell 12 is hinged to the cross beam 9. The front and rear sides of the thread rolling machine are covered by the front cover shell 11 and the rear cover shell 12, which can play a protective role. Since the front cover shell 11 and the rear cover shell 12 are both hinged, when the thread rolling machine needs to be repaired, it is only necessary to flip the front cover shell 11 and the rear cover shell 12 upwards, so that the internal structure of the thread rolling machine can be exposed to the outside, so that the front cover shell 11 and the rear cover shell 12 do not need to be disassembled to repair them, which is convenient and quick. At the same time, a protective cover 4 is also arranged on the upper fuselage 2 to cover the slide seat 3 to protect the slide seat 3 and prevent dust from entering the slide seat 3.

[0082] The above-mentioned control and display module 20 is connected to the electric control cabinet 19, and the electric control cabinet 19 is connected to the corresponding components in the upper body 2 to supply power to it and control its operation. The control and display module 20 can be manually controlled to adjust the operating parameters. Various parameters during the working process of the thread rolling machine will also be displayed in real time on the control and display module 20. The control and display module 20 can control the heating temperature and the operation of the thread rolling machine.

[0083] After actual processing, the thread rolling machine used continuous rolling to process 1,000 pieces of aviation industry-grade 0.25-28UNJF-3A high-precision titanium alloy threads. The processing verification result was that the thread diameter discrete value was 3 microns, and there was no deviation in the thread (the highest level of thread diameter discrete value of other thread rolling machines is 30 microns, and the thread deviation is within 3 threads). It can be clearly seen that the processing accuracy has been greatly improved. Fig.25 As shown in the figure, this is a test report issued after the workpiece is processed. It is not difficult to find from the test report that the deviation of the workpiece after processing is very small and the processing accuracy is significantly improved.

[0084] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
