Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, specifically to a multi-station fastener production and tapping machine. Background Technology

[0002] Multi-station fastener tapping machines are core equipment in the fastener production field and are widely used in industries such as automobiles, construction machinery, and aerospace. They are mainly used for internal thread processing of fastener nuts, and their processing efficiency and processing stability directly affect the production quality and capacity of fasteners.

[0003] In actual production, existing multi-station tapping machines usually have separate liquid supply mechanisms and anti-splash structures to achieve tap cooling and lubrication and protection of the machining environment. These structures are mostly designed with separate control, requiring operators to operate them separately to open and close them. This makes it difficult to accurately synchronize the timing of liquid supply with the tapping action of the tapping components. This can easily lead to ineffective waste of cutting fluid and may also cause the tap to wear too quickly due to untimely liquid supply in the early stages of tapping, affecting the service life of the tap and the machining accuracy.

[0004] Meanwhile, the existing equipment's anti-splash structure and tapping components move asynchronously, and the protective gap is prone to deviation. Cutting chips and cutting fluid are easily splashed onto the equipment's transmission parts, increasing the equipment failure rate. Furthermore, some equipment relies on electrical control to achieve structural reset and fluid supply switching, which further increases the equipment's structural complexity, manufacturing costs, and subsequent maintenance costs. Therefore, there is an urgent need to develop a multi-station fastener manufacturing tapping machine to solve these practical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-station fastener manufacturing tapping machine, which solves the technical problems of asynchronous liquid supply and anti-splash structure separation in existing multi-station tapping machines, reliance on electrical control, and easy increase in failures and equipment costs.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a multi-station fastener manufacturing tapping machine, including a housing, three sets of equidistant mounting brackets are fixed to one side of the top of the housing, an electric rod runs through the inside of the mounting bracket, and a tapping component for tapping fasteners is provided at the bottom of the electric rod, and a protective cover is provided on the top of the tapping component.

[0007] It also includes a linkage liquid supply anti-splash mechanism, which includes a connecting frame fixed to one side of the tapping assembly. An elastic compression component is provided on the top of the connecting frame. A support rod is driven at the bottom of the elastic compression component. A hollow enclosure for anti-splash protection of the tapping rod is fixed to the bottom of the support rod. A rack is also fixed to one side of the support rod.

[0008] Two sets of corresponding placement platforms are fixed to the top of the enclosure on the side away from the mounting frame.

[0009] Preferably, the linkage liquid supply anti-splash mechanism further includes a valve body fixed to one side of the connecting frame. A ball valve for opening and closing the liquid passage is rotatably installed inside the valve body. A gear plate coaxially connected to the ball valve is rotatably installed on the front of the valve body. The gear plate meshes with a rack and pinion, and the rack passes through the inside of the connecting frame and slides with the connecting frame. A pressure rod for driving the hollow enclosure to reset is also provided at the bottom of the mounting frame.

[0010] Preferably, the meshing parameters of the rack and the toothed disc are matched, and the linear travel of the rack matches the meshing travel of the toothed disc rotating around its own axis. The linear travel of the rack along the connecting frame can drive the toothed disc to rotate once, thereby driving the ball valve to rotate once synchronously in the valve body, so that the liquid passage inside the valve body is opened.

[0011] Preferably, the elastic compression assembly includes a housing fixed to the top of the connecting frame, an axially arranged spring fixed inside the housing, and the top end of the support rod passing through the connecting frame and the housing in sequence, and being fixedly connected to the bottom end of the spring. When the support rod is forced to move, it can drive the spring to perform axial elastic compression.

[0012] Preferably, the holding rod is vertically fixed to the bottom of the mounting frame, and the bottom end of one side of the holding rod abuts against the top of the hollow enclosure. When the hollow enclosure moves upward, the holding rod drives the hollow enclosure to return to its original position downward through the abutting force.

[0013] Preferably, the inner side of the placement platform is provided with a positioning groove for positioning the fastener nut. The position of the positioning groove is coaxial with the position of the tapping rod in the tapping assembly. After the tapping rod completes the tapping process, it rotates in the opposite direction to disengage the fastener nut from the external thread of the tapping rod.

[0014] Preferably, a liquid circulation assembly is also provided inside the box. The liquid circulation assembly includes a collection box that is slidably connected to the inner wall of the box. A perforated metal plate for filtering metal cutting debris is horizontally fixed inside the collection box. A drain pipe for discharging filtered liquid is also connected to the side of the collection box away from the box. The collection box can slide out along the inner wall of the box to clean the filtered metal cutting debris.

[0015] Preferably, the tapping assembly includes three sets of equidistant sliding rods fixed to the top of the housing near the mounting bracket. A movable bracket is slidably mounted on the outside of the sliding rods. A motor is fixed to one side of the movable bracket. A tapping rod is rotatably mounted on the side of the movable bracket away from the motor. A transmission assembly is provided on the top of the motor. The two ends of the transmission assembly are respectively connected to the output shaft of the motor and the top end of the tapping rod to drive the tapping rod to rotate around its own axis.

[0016] Preferably, the top of the box is also provided with an auxiliary feeding component. The auxiliary feeding component includes three sets of equidistant and movable contact frames that pass through the top of the box. A return spring is fixedly connected to the rod inside the box of the contact frame. The top of the return spring is fixedly connected to the top of the inside of the box. The top of the contact frame extends to the bottom of the positioning groove inside the placement platform and is fixedly connected with a contact head.

[0017] The top side of the contact frame abuts against the top of the protective cover. The protective cover moves upward, and the contact frame moves upward synchronously through the contact force. This causes the contact head to lift the fastener nut upward and disengage it from the positioning groove. After the contact frame loses its contact force, it returns to its original position downward through the elastic restoring force of the return spring.

[0018] Preferably, the return spring is fixed to the top of the contact frame, and both ends of the return spring are fixed to the top of the inner side of the box and the rod of the contact frame, respectively, to provide a stable axial return force.

[0019] This invention provides a multi-station fastener manufacturing tapping machine. Compared with the prior art, it has the following advantages:

[0020] 1. The connecting frame drives the support rod and hollow enclosure to move synchronously. The rack and pinion meshing transmission controls the on / off state of the ball valve. Combined with the mechanical reset of the holding rod and the elastic reset of the spring, the tapping, fluid supply, and anti-splash linkage is realized. This prevents cutting fluid and chip splashing, accurately controls the timing of fluid supply, avoids excessive wear of the tap and waste of cutting fluid, reduces dependence on electrical control components, simplifies the equipment structure, reduces manufacturing and maintenance costs, and improves equipment stability and processing efficiency.

[0021] 2. By linking the protective cover with the contact frame, the contact head lifts the processed nut and automatically resets it with the help of the return spring. The unloading can be completed without manual intervention, avoiding nut bumps and misalignment caused by manual operation, reducing manual operation steps, improving unloading efficiency and product qualification rate, ensuring processing continuity, and further improving the overall processing efficiency of the equipment.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] First implementation method:

[0035] refer to Figure 1-5 , Figure 7-10 A multi-station fastener manufacturing tapping machine includes a housing 1. Three sets of equidistant mounting brackets 101 are fixed to one side of the top of the housing 1. An electric rod 102 passes through the inside of the mounting bracket 101. A tapping assembly 103 for tapping fasteners is provided at the bottom of the electric rod 102. A protective cover 104 is also provided on the top of the tapping assembly 103.

[0036] It also includes a linkage liquid supply anti-splash mechanism 2, which includes a connecting frame 201 fixed to one side of the tapping assembly 103. An elastic compression assembly 202 is provided on the top of the connecting frame 201. A support rod 203 is driven at the bottom of the elastic compression assembly 202. A hollow enclosure cover 204 for anti-splash protection of the tapping rod 1035 is fixed to the bottom of the support rod 203. A rack 2031 is also fixed to one side of the support rod 203.

[0037] Two sets of corresponding placement platforms 3 are fixedly connected to the top of the box 1 on the side away from the mounting bracket 101;

[0038] The linkage-type liquid supply anti-splash mechanism 2 also includes a valve body 205 fixed to one side of the inside of the connecting frame 201. A ball valve 206 for opening and closing the liquid passage is rotatably installed inside the valve body 205. A gear plate 207 coaxially connected to the ball valve 206 is rotatably installed on the front of the valve body 205. The gear plate 207 meshes with the rack 2031 for transmission. The rack 2031 passes through the inside of the connecting frame 201 and slides with the connecting frame 201. A pressure rod 208 for driving the hollow enclosure cover 204 to reset is also provided at the bottom of the mounting frame 101.

[0039] The meshing parameters of rack 2031 and gear disc 207 are matched. The linear travel of rack 2031 matches the meshing travel of gear disc 207 rotating around its own axis. The linear movement of rack 2031 along connecting frame 201 can drive gear disc 207 to rotate one revolution, thereby driving ball valve 206 to rotate one revolution synchronously in valve body 205, so that the liquid passage inside valve body 205 is opened.

[0040] The elastic compression assembly 202 includes a housing 2021 fixed to the top of the connecting frame 201. An axially arranged spring 2022 is fixed inside the housing 2021. The top end of the support rod 203 passes through the connecting frame 201 and the housing 2021 in sequence and is fixedly connected to the bottom end of the spring 2022. When the support rod 203 is forced to move, it can drive the spring 2022 to perform axial elastic compression.

[0041] The holding rod 208 is vertically fixed to the bottom of the mounting bracket 101. The bottom end of one side of the holding rod 208 abuts against the top of the hollow enclosure 204. When the hollow enclosure 204 moves upward, the holding rod 208 drives the hollow enclosure 204 to return to its original position downward through the abutting force.

[0042] The inner side of the placement table 3 is provided with a positioning groove for positioning the fastener nut. The opening position of the positioning groove is coaxial with the axis position of the tapping rod 1035 in the tapping assembly 103. After the tapping is completed, the tapping rod 1035 rotates in the opposite direction to disengage the fastener nut from the external thread of the tapping rod 1035.

[0043] The tapping assembly 103 includes three sets of equidistant slide rods 1031 fixed to the top of the housing 1 near the mounting bracket 101. A movable bracket 1032 is slidably mounted on the outside of the slide rods 1031. A motor 1033 is fixed to one side of the movable bracket 1032. A tapping rod 1035 is rotatably mounted on the side of the movable bracket 1032 away from the motor 1033. A transmission assembly 1034 is provided on the top of the motor 1033. The two ends of the transmission assembly 1034 are respectively connected to the output shaft of the motor 1033 and the top end of the tapping rod 1035 to drive the tapping rod 1035 to rotate around its own axis.

[0044] Working principle: After the operator places the fastener nut into the positioning groove inside the placement platform 3, the telescopic pipe at the top of the valve body 205 is connected to the external cutting fluid supply pump. The linkage-type fluid supply and anti-splash mechanism 2 in this embodiment completely solves the technical problems of separate control of fluid supply and anti-splash in traditional multi-station tapping machines, cumbersome fluid supply and inaccurate fluid supply timing leading to excessive wear of the machining tap through mechanical linkage structure. The specific working process and optimization effect are as follows;

[0045] The motor 1033 drives the transmission component 1034 to drive the tapping rod 1035 to rotate around its own axis. At the same time, the electric rod 102 drives the moving frame 1032 to move vertically down along the slide rod 1031, thereby moving the tapping rod 1035 down to the top of the placement table 3 and tapping the fastener nut in the positioning groove.

[0046] The vertically moving frame 1032 synchronously drives the connecting frame 201 to move down, which in turn drives the support rod 203 and the hollow enclosure 204 to move down synchronously, so that the hollow enclosure 204 abuts against the top of the placement table 3, forming a full-coverage anti-splash protection for the outside of the tapping rod 1035. This design avoids the problems of traditional equipment splash guards and tapping components being out of sync and having too large protective gaps, which cause cutting chips and cutting fluid to splash onto the equipment surface, the operator's workbench and the ground. It not only protects the cleanliness of the processing environment, but also avoids mechanical failures caused by chip accumulation in the transmission parts of the equipment, and also reduces the safety hazard of operators being scratched by chips.

[0047] As the electric rod 102 continues to operate, the tapping rod 1035 penetrates into the nut to tap the thread. At this time, the bottom of the hollow enclosure 204 is subjected to the resistance force of the placement platform 3. Through the support rod 203, the spring 2022 inside the housing 2021 is compressed, causing the support rod 203 to retract into the housing 2021. Simultaneously, the rack 2031 moves upward. The setting of the spring 2022 can realize the self-adaptive resistance of the hollow enclosure 204, adapting to the processing of nuts of different thicknesses and specifications. This avoids the problems of traditional splash guards having a fixed height, being unable to adapt to multiple specifications of workpieces, easily damaging the nut surface, or being inadequate in protection.

[0048] The upward-moving rack 2031 drives the gear disk 207 to rotate around its own axis by precise meshing with the gear disk 207, thereby driving the ball valve 206 to rotate synchronously within the valve body 205, forming a liquid conduction passage inside the valve body 205. This linkage structure realizes the precise control of automatic liquid supply when the tapping rod is deeply engaged in tapping, completely solving the technical problems of traditional equipment requiring manual activation of liquid supply, asynchronous liquid supply timing with tapping action, resulting in no cooling and lubrication of the tap in the early stage of tapping, excessive wear, and excessive liquid supply and waste of cutting fluid in the later stage of tapping.

[0049] The cutting fluid supplied by the external pump is delivered to the interior of the hollow baffle 204 through the valve body 205, and then precisely sprayed into the contact area between the tap rod 1035 and the nut through the slots on the inner side of the hollow baffle 204. This not only provides sufficient cooling and lubrication to the tap rod 1035, reducing the wear rate of the tap and extending its service life, but also precisely flushes and cleans the metal chips generated during processing, avoiding the problems of rough thread surface and reduced machining accuracy caused by chips remaining in the thread groove. At the same time, the fully enclosed structure of the hollow baffle 204 allows the cutting fluid and chips to be collected in a concentrated manner, avoiding the drawbacks of traditional fluid supply dispersion, excessively rapid loss of cutting fluid, and difficulty in chip cleaning.

[0050] After the tapping operation is completed, the electric rod 102 drives the moving frame 1032 to move upward along the slide rod 1031, and simultaneously drives the connecting frame 201, support rod 203, and hollow enclosure 204 to move upward. At this time, the bottom end of the holding rod 208 abuts against the top of the hollow enclosure 204, and the abutting force drives the hollow enclosure 204 to reset downward, and simultaneously drives the support rod 203 and rack 2031 to move downward. The mechanical reset structure of the holding rod 208 avoids the problems of traditional equipment requiring an additional reset motor, increasing equipment costs, and being prone to electrical faults that cause reset failure.

[0051] The downward-moving rack 2031 drives the gear plate 207 to rotate in the opposite direction through meshing transmission, which in turn drives the ball valve 206 to rotate to the closed state, cutting off the liquid passage inside the valve body 205, realizing the linkage control of automatic liquid cut-off when tapping ends, further avoiding the ineffective loss of cutting fluid, reducing processing costs, and also avoiding the problems of equipment corrosion and processing environment pollution caused by continuous dripping of cutting fluid.

[0052] After tapping is completed, the tapping rod 1035 immediately rotates in the opposite direction, causing the internal thread of the nut to disengage from the external thread of the tapping rod 1035.

[0053] In summary, the linkage-type liquid supply and anti-splash mechanism 2 achieves the linkage function of anti-splash protection and automatic liquid cut-off through the mechanical linkage design of the tapping component and the liquid supply and anti-splash structure. It solves the technical problems of traditional multi-station tapping machines, such as separate control of liquid supply and anti-splash, cumbersome operation, and untimely liquid supply leading to rapid tap wear and cutting fluid waste.

[0054] Meanwhile, the hollow enclosure cover 204 automatically applies pressure to prevent splashing by mechanically resetting the pressure rod 208 and elastically resetting the spring 2022, which reduces the device's dependence on electrical control components, simplifies the equipment structure, and reduces the equipment manufacturing and maintenance costs.

[0055] Second implementation method:

[0056] In the actual use of traditional multi-station tapping machines, due to the design defects of direct discharge of cutting fluid and difficulty in chip cleaning, the processing cost is easily increased due to waste of cutting fluid and accumulation of metal chips. Therefore, this device is also designed with a liquid circulation component, the structure and working principle of which are as follows.

[0057] refer to Figure 3-5 In a second embodiment of the present invention, a liquid circulation assembly 4 is further provided inside the housing 1. The liquid circulation assembly 4 includes a collection box 401 slidably connected to the inner wall of the housing 1. A perforated metal plate 402 for filtering metal cutting debris is horizontally fixed inside the collection box 401. A drain pipe for discharging filtered liquid is also connected to the side of the collection box 401 away from the housing 1. The collection box 401 can slide out along the inner wall of the housing 1 to clean up the filtered metal cutting debris.

[0058] Working principle: Metal chips and cutting fluid generated from wire cutting flow into the collection tank 401 through the drain hole of the positioning slot of the placement platform 3. The metal porous plate 402 filters the mixture. The metal chips are intercepted at the top of the metal porous plate 402, and the filtered cutting fluid flows into the bottom of the collection tank 401 through the pores of the metal porous plate 402.

[0059] The drain pipe 403 on one side of the collection tank 401 is connected to an external cutting fluid circulation pump, which can transport the filtered cutting fluid back to the supply pump, realize the recycling of cutting fluid, and avoid the waste of resources and environmental pollution caused by the direct discharge of cutting fluid in traditional equipment.

[0060] When the debris on the top of the perforated metal plate 402 accumulates to a certain amount, the operator can slide the collection box 401 along the inner wall of the box 1 to directly clean the debris on the top of the perforated metal plate 402 without disassembling the equipment, which improves the convenience of debris cleaning and solves the problems of decreased processing accuracy and increased equipment wear caused by debris accumulation in traditional equipment.

[0061] The third implementation method:

[0062] In the actual use of traditional multi-station tapping machines, manual feeding is inefficient and prone to nut collisions and misalignment due to human error. Therefore, this device is also designed with an auxiliary feeding component, the structure and working principle of which are as follows.

[0063] refer to Figure 5-6In the third embodiment of the present invention, an auxiliary feeding component 5 is also provided on the top of the box 1. The auxiliary feeding component 5 includes three sets of equidistant and movable contact frames 501 that pass through the top of the box 1. A return spring 503 is fixedly connected to the rod inside the box 1 of the contact frame 501. The top end of the return spring 503 is fixedly connected to the top of the inner side of the box 1. The top end of the contact frame 501 extends to the bottom of the positioning groove inside the placement platform 3 and is fixedly connected to the contact head 502.

[0064] The top side of the contact bracket 501 abuts against the top of the protective cover 104. The protective cover 104 moves upward and drives the contact bracket 501 to move upward synchronously through the contact force, thereby driving the contact head 502 to lift the fastener nut upward and disengage it from the positioning groove. After the contact bracket 501 loses the contact force, it is reset downward through the elastic restoring force of the return spring 503.

[0065] The return spring 503 is fixed to the top of the abutment frame 501, and the two ends of the return spring 503 are fixed to the top of the inner side of the housing 1 and the rod of the abutment frame 501, respectively, to provide a stable axial return force.

[0066] Working principle: After the tapping operation is completed, the moving frame 1032 moves upward along the slide rod 1031, and simultaneously drives the protective cover 104 to move upward. The top of the protective cover 104 abuts against one side of the top of the contact frame 501. Through the contact force, the contact frame 501 moves upward synchronously. At this time, the return spring 503 is compressed and produces elastic deformation.

[0067] The upward-moving contact frame 501 drives the contact head 502 to move upward into the positioning groove of the placement table 3, lifting the processed nut upward and causing the nut to leave the positioning groove, thus realizing automatic unloading and avoiding the inefficiency and nut damage caused by manual unloading.

[0068] When the moving frame 1032 moves the protective cover 104 down to the initial position, the contact force between the protective cover 104 and the contact frame 501 disappears. The contact frame 501 resets downward under the elastic restoring force of the return spring 503, driving the contact head 502 back to the initial position at the bottom of the positioning groove, preparing for the next feeding action.

[0069] The auxiliary feeding component 5, through its linkage with the tapping component 103, enables automatic feeding after tapping, thereby improving production efficiency and solving the problems of long processing cycles and low product qualification rates caused by traditional manual feeding.

[0070] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
