Description

Technical Field

[0001] This application relates to the field of hardware manufacturing technology, and in particular to a workpiece fixing structure for a vertical tapping machine. Background Technology

[0002] Hardware components, with their high strength, corrosion resistance, and excellent mechanical properties, are widely used in machinery manufacturing, architectural decoration, and electronics. From precision instrument parts to structural components of large buildings, all rely on the support of hardware components. In practical applications, to achieve reliable connections and assembly between parts, it is often necessary to machine internal threads onto the workpiece, i.e., tapping. Tapping allows standard parts such as bolts and screws to fit tightly with hardware components, ensuring a stable connection between parts and meeting the needs of various usage scenarios.

[0003] The process of tapping metal parts mainly includes three stages: preparation, machining, and inspection. In the preparation stage, appropriate taps and tapping equipment must be selected based on the workpiece material, size, and design requirements. The workpiece surface must also be checked for smoothness and burrs. During machining, a pilot hole is first drilled using a drill bit. Then, a tap is screwed into the pilot hole using a tapping machine or manual tools. Cutting is performed according to the predetermined speed and feed rate to form an internal thread.

[0004] Most existing tapping machines transport workpieces to the tapping mechanism via a conveyor plate, and then use structural limiters to simply restrict and fix the workpieces before the tapping mechanism processes them. However, during the tapping process, the workpieces are subjected to forces that cause them to vibrate or shift. If the workpieces are not clamped and fixed, it will lead to deviations in thread size and incomplete tooth profiles, affecting processing accuracy and product quality, which is not conducive to the processing of workpieces. Utility Model Content

[0005] The purpose of this application is to solve the problem in the above-mentioned background technology that when tapping a workpiece, the workpiece will vibrate or shift due to the force applied. If the workpiece is not clamped and fixed, it will lead to deviation in thread size and incomplete tooth profile, affecting the processing accuracy and product quality, which is detrimental to the processing of the workpiece. This application provides a workpiece fixing structure for a vertical tapping machine.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A workpiece fixing structure for a vertical tapping machine includes a base, an installation platform fixedly connected to the center of the base, a material shaking disc fixedly connected to one side of the base, a turntable mounted on the installation platform, a through-hole mechanism fixedly connected to one side of the top end of the installation platform, a tapping mechanism fixedly connected to the other side of the top end of the installation platform, mutually symmetrical fixing components fixedly connected to one side of the installation platform, the fixing components corresponding to the turntable, a material discharge component mounted on one side of the installation platform, and a limit plate mounted on one side of the installation platform.

[0008] By adopting the above technical solution, when the through-hole mechanism or tapping mechanism processes the workpiece, the operation of the fixing component can drive the internal components of the fixing component towards the workpiece. The internal components squeeze the workpiece and fix it on the turntable, thereby fixing the workpiece in conjunction with the turntable. This prevents the possibility of shaking or displacement when the through-hole mechanism or tapping mechanism processes the workpiece, improves the processing quality of the workpiece, and thus increases the yield of the workpiece.

[0009] Furthermore, the discharge component includes a guide plate fixedly connected to one side of the mounting platform, and a discharge tray is fixedly connected to the lower end of one side of the mounting platform.

[0010] By adopting the above technical solution, the workpiece in the feed trough is limited and moved by the guide plate, and the workpiece is pulled out of the feed trough as the turntable rotates.

[0011] Furthermore, the outer arc of the turntable is provided with multiple equidistant material conveying troughs.

[0012] By adopting the above technical solution, the workpiece can enter the conveying trough and be transported as the turntable rotates.

[0013] Furthermore, an oil reservoir is provided on one side of the interior of the base, and an injector is fixedly connected to the top of the oil reservoir.

[0014] By adopting the above technical solution, the cutting oil inside the oil tank can be delivered to the workpiece through the oil injector.

[0015] Furthermore, the fixing assembly includes a base fixedly connected to one side of the mounting platform, a cylinder fixedly connected to one side of the base, a cylinder rod connector fixedly connected to the output end of the cylinder, and a pressing member installed at one end of the cylinder rod connector.

[0016] By adopting the above technical solution, the operation of the cylinder can drive the cylinder rod connector to operate, thereby driving the extruded part.

[0017] Furthermore, the extrusion component includes a drive block installed at one end of the cylinder rod connector, a detachable fixing block installed at one end of the drive block, a guide rail fixedly connected to the base, and the drive block slidably mounted on the guide rail.

[0018] By adopting the above technical solution, the workpiece can be squeezed and fixed by the fixing block.

[0019] Furthermore, the fixed block has a fixed arc opening at one end away from the driving block, and the fixed arc opening corresponds to the material conveying trough.

[0020] By adopting the above technical solution, the workpiece is fixed inside the feed trough by the inner wall of the fixed arc and the outer wall of the workpiece being in contact with each other.

[0021] Furthermore, an anti-slip layer is provided on the inner arc side of the fixed arc opening.

[0022] By adopting the above technical solution, the anti-slip layer can increase the friction between the inner wall of the fixed arc and the outer wall of the workpiece, thereby improving the fixing strength of the workpiece.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when the through-hole mechanism or tapping mechanism processes the workpiece, the operation of the fixing component can drive the internal components of the fixing component toward the workpiece, and the internal components squeeze the workpiece and fix it on the turntable. In turn, the turntable fixes the workpiece, thereby preventing the possibility of shaking or displacement when the through-hole mechanism or tapping mechanism processes the workpiece, improving the processing quality of the workpiece, and thus improving the yield of the workpiece.

[0025] 2. In this application, before the through-hole mechanism or tapping mechanism processes the workpiece, the fixing component can be adjusted according to the size of the workpiece, and the extrusion component of the fixing component can be replaced to adapt to extrusion components of different sizes. This is used in conjunction with the turntable to fix workpieces of different sizes, making it convenient for the tapping machine to process workpieces of different sizes, thereby improving workpiece production efficiency.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0033] This application discloses a workpiece fixing structure for a vertical tapping machine.

[0034] Reference Figure 1 and Figure 2 A workpiece fixing structure for a vertical tapping machine includes a base 1, an mounting platform 2 fixedly connected to the middle of the base 1, a material shaking disc 4 fixedly connected to one side of the base 1, a turntable 3 mounted on the mounting platform 2, a through-hole mechanism 5 fixedly connected to one side of the top end of the mounting platform 2, a tapping mechanism 6 fixedly connected to the other side of the top end of the mounting platform 2, symmetrical fixing components 7 fixedly connected to one side of the mounting platform 2, the fixing components 7 corresponding to the turntable 3, a material discharge component mounted on one side of the mounting platform 2, a limit plate 8 mounted on one side of the mounting platform 2, the material discharge component including a guide plate 9 fixedly connected to one side of the mounting platform 2, a discharge disc 10 fixedly connected to the lower end of one side of the mounting platform 2, and multiple equidistant material conveying grooves 31 provided on the outer arc of the turntable 3.

[0035] When processing a workpiece, it is first placed in the shaking disc 4. The shaking disc 4 then transports the workpiece to the conveying trough 31. Next, the turntable 3 transports the workpiece directly below the tapping mechanism 6. During movement, the limiting plate 8 guides and blocks the workpiece, thus coordinating with the turntable 3 for transport. When the workpiece reaches the area directly below the tapping mechanism 6, the fixing component 7 on one side rotates, causing its internal components to drive the workpiece and thus fix it in place within the conveying trough 31. Finally, the tapping mechanism 6 performs tapping processing on the workpiece. After processing, the fixing component 7 on one side can be released from fixing the workpiece. At this time, the workpiece is transported to the through hole mechanism 5 by the rotation of the turntable 3. The workpiece is fixed again by the fixing component 7 on the other side. The workpiece can be enlarged by the operation of the through hole mechanism 5. After enlarging the hole, the fixing component 7 on the other side can be released from fixing the workpiece. At this time, the turntable 3 can rotate again to transport the processed workpiece. The workpiece in the feed trough 31 is limited and moved by the guide plate 9. As the turntable 3 rotates, the workpiece is pulled out from the feed trough 31, so that the workpiece falls into the discharge plate 10. The workpiece is guided into the external storage box by the discharge plate 10, thereby realizing the processing of the workpiece.

[0036] Reference Figure 3 An oil reservoir 11 is provided on one side of the base 1, and an injector 12 is fixedly connected to the top of the oil reservoir 11.

[0037] The oil injector 12 can extract cutting oil from the oil tank 11 and deliver it to the machining area of ​​the through-hole mechanism 5 and the tapping mechanism 6. This sprays the workpiece and the cutting head of the through-hole mechanism 5 or the tapping mechanism 6, thereby cooling and lubricating them, preventing the workpiece or cutting head from deforming and being damaged due to excessive temperature rise, and improving the machining quality of the workpiece.

[0038] Reference Figure 4 The fixing component 7 includes a base 71 fixedly connected to one side of the mounting platform 2. A cylinder 73 is fixedly connected to one side of the base 71. A cylinder rod connector 74 is fixedly connected to the output end of the cylinder 73. An extrusion component is installed at one end of the cylinder rod connector 74. The extrusion component includes a drive block 75 installed at one end of the cylinder rod connector 74. A detachable fixing block 76 is installed at one end of the drive block 75. A guide rail 72 is fixedly connected to the base 71. The drive block 75 is slidably installed on the guide rail 72. A fixing arc opening 77 is opened at the end of the fixing block 76 away from the drive block 75. The fixing arc opening 77 corresponds to the material conveying trough 31. An anti-slip layer 78 is provided on the inner arc side of the fixing arc opening 77.

[0039] When fixing the workpiece, the operation of cylinder 73 causes cylinder rod connector 74 to extend and drive drive block 75, causing drive block 75 to slide on guide rail 72, thereby moving fixed block 76 toward the workpiece. This causes the inner wall of fixed arc opening 77 to fit against the outer wall of the workpiece, thus fixing the workpiece inside the feed trough 31, so that through hole mechanism 5 or tapping mechanism 6 can process the workpiece. During this process, anti-slip layer 78 can increase the friction between the inner wall of fixed arc opening 77 and the outer wall of the workpiece, thereby improving the fixing strength of the workpiece. Here, drive block 75 and fixed block 76 are fixedly connected by bolts. When it is necessary to replace fixed block 76 according to workpiece size, the bolts can be manually removed to replace fixed block 76.

[0040] Working Principle: When processing a workpiece, the workpiece is first placed in the shaking disc 4. The shaking disc 4 rotates, conveying the workpiece into the feed trough 31. Then, the turntable 3 rotates, conveying the workpiece directly below the tapping mechanism 6. During the movement, the workpiece is blocked and guided by the limiting plate 8, thus coordinating with the turntable 3 for conveying. When the workpiece reaches directly below the tapping mechanism 6, the fixing component 7 on one side rotates, causing the cylinder 73 to extend the cylinder rod connector 74, which in turn drives the drive block 75. The drive block 75 slides on the guide rail 72, causing the fixing block 76 to move towards the workpiece. This allows the inner wall of the fixing arc 77 to contact the outer wall of the workpiece, thus fixing the workpiece inside the feed trough 31. The workpiece is processed by the through-hole mechanism 5 or the tapping mechanism 6. After that, the tapping mechanism 6 performs tapping on the workpiece. After processing, the fixing component 7 on one side can be released from fixing the workpiece. At this time, the workpiece is transported to the through-hole mechanism 5 by the rotation of the turntable 3. The workpiece is fixed again by the fixing component 7 on the other side. The through-hole mechanism 5 can enlarge the hole in the workpiece. After enlarging the hole, the fixing component 7 on the other side can be released from fixing the workpiece. At this time, the turntable 3 can rotate again to transport the processed workpiece. The workpiece in the feed trough 31 is limited and moved by the guide plate 9. As the turntable 3 rotates, the workpiece is pulled out from the feed trough 31 and falls into the discharge plate 10. The discharge plate 10 guides the workpiece into the external storage box, thereby realizing the processing of the workpiece.
