Description

Technical Field

[0001] The invention relates to the technical field of metal processing equipment, and more particularly to an adjustable drilling and tapping equipment for vise processing. Background Art

[0002] A bench vise, also known as a vice or bench vise, is an important tool widely used to clamp and fix workpieces for various processing operations. It is not only an indispensable basic equipment for bench workers, but also gets its name because most of the bench work is done on the bench vise, such as sawing, filing, chiseling, and assembly and disassembly of parts.

[0003] The vise drilling and tapping equipment currently on the market generally follows the two major steps of drilling and tapping when processing parts. However, during the drilling process, these devices often lack an efficient heat dissipation mechanism, resulting in damage to the parts and the drill bit due to the high temperature generated by friction, and the durability of the drill bit cannot be effectively guaranteed. On the other hand, during the tapping stage, since the parts usually need to be heated to a certain extent to soften the material and reduce the difficulty of cutting, excessive strength and hardness may cause a sharp increase in cutting resistance, thereby causing the risk of material cracking and accelerating the wear of the tap. In severe cases, it may even cause the tap to break during the tapping process. In view of this, we propose an adjustable vise drilling and tapping equipment for processing. Summary of the invention

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. By designing a rotating component, an exhaust component and an air inlet component, during drilling, the drill bit presses the workpiece to be processed, causing the workpiece to be processed to push the gripper to press the pressure component. During tapping, the exhaust component will extract the air in the heat exchange component through the heater, and then discharge the heated gas to the surface of the workpiece to be processed, so as to heat-treat the workpiece to be processed. On the one hand, during drilling, the air flow rate below the workpiece to be processed can be accelerated, so as to accelerate the heat dissipation of the workpiece to be processed and avoid damaging the workpiece to be processed and the drill bit during the drilling stage. On the other hand, during tapping, the lower part of the workpiece to be processed will also be heated. By continuously heating, the hardness of the workpiece to be processed is reduced, the loss of the tap is reduced, and the workpiece to be processed and the tap are prevented from being damaged. The device ensures the quality of the workpiece to be processed and improves the processing efficiency.

[0027] 2. The present invention also designs a rotating component, an air inlet component and a pressure component. During drilling, the drill bit continuously presses the workpiece to be processed, causing the workpiece to be processed to push the gripper, so that the first sliding rod slides into the first sliding sleeve. During this process, the toothed plate will push the gear. When the air in the first sliding sleeve completely enters the second sliding sleeve, the toothed plate will disengage from the gear, causing the gear to reset under the elastic force of the coil spring. At this time, the liquid in the heat exchange cylinder will adsorb impurities and transfer heat, so that the device can, on the one hand, dissipate heat from the workpiece to be processed during drilling, and on the other hand, during the heat dissipation process of the workpiece, the metal chips generated during drilling can be collected and stored synchronously, avoiding resource waste and protecting the personnel.

[0028] 3. The present invention also designs an exhaust component and a rotating component. During tapping, since the tap does not need to continuously extrude the workpiece, the second slide rod will keep the toothed plate and the gear in contact. At this time, the flipped first slide plate will push the rubber pad on the sealing plate to dock with the plug, ensuring that air can be directly injected into the first slide plate and preventing air leakage. Similarly, when the plug is not docked with the rubber pad, the air will be discharged along the pressure valve, preventing a large amount of hot air from being directly discharged onto the surface of the workpiece during heat dissipation treatment, ensuring that the device can stably heat the workpiece during the tapping stage and stably dissipate heat from the workpiece during the drilling stage, improving the stability of the device during use.

[0048] As Figures 1 to 8 shown, an adjustable drilling and tapping device for bench vice processing according to the present invention includes

[0049] The vise mechanism 1 includes a base 101, an adjusting rod 102 disposed above the base 101, a protective shell 103, a control grip 104, a driver 105 located outside the protective shell 103, and an adjusting sleeve 106 located outside the adjusting rod 102. Among them, the protective shell 103 is located at the top of the adjusting rod 102, and the control grip 104 is located outside the protective shell 103. And the protection mechanism 2 includes a platform assembly 201, a pressure assembly 202 connected to the platform assembly 201, a rotating assembly 203 located inside the platform assembly 201, an exhaust assembly 204, an intake assembly 205, a heat exchange assembly 207 connected to the exhaust assembly 204 and the intake assembly 205, an adjusting assembly 206 connected to the rotating assembly 203, and a workpiece 208 to be processed located inside the platform assembly 201. Among them, the exhaust assembly 204 is connected to the rotating assembly 203, and the intake assembly 205 is connected to the pressure assembly 202. During drilling, the drill bit presses the workpiece 208 to be processed, causing the workpiece 208 to push the gripper 2013 to press the pressure assembly 202, and by pushing the internal pressure of the pressure assembly 202 into the adjusting assembly 206. At this time, the adjusting assembly 206 will adjust the angle of the rotating assembly 203, and as the adjusting assembly 206 continues to extend, the adjusting assembly 206 will separate from the rotating assembly 203, and the rotating assembly 203 will reset. And the intake assembly 205 will continue to operate, extract the air below the workpiece 208 to be processed and discharge it into the heat exchange assembly 207, and the liquid in the heat exchange assembly 207 absorbs the heat and metal impurities in the gas to complete the heat dissipation and dust collection effects during drilling. And during tapping, since the tap does not need to be tapped by a continuously downward pressing force, after the tap is initially pressed into the workpiece 208 to be processed, a slight pressure can be maintained to continuously tap downward. When the pressure assembly 202 extends the adjusting assembly 206 by pressure, the angle of the exhaust assembly 204 will be adjusted through the rotating assembly 203. Subsequently, the exhaust assembly 204 will extract the air in the heat exchange assembly 207 through the heater, and then discharge the heated gas to the surface of the workpiece 208 to be processed, thereby heating the workpiece 208 to be processed. On the one hand, the device can accelerate the air flow rate below the workpiece 208 to be processed during drilling, thereby accelerating the heat dissipation of the workpiece 208 to be processed and avoiding damage to the workpiece 208 to be processed and the drill bit during the drilling stage. On the other hand, during tapping, the lower part of the workpiece 208 to be processed will also be heated. By continuously heating, the hardness of the workpiece 208 to be processed is reduced, the loss of the tap is reduced, and damage to the workpiece 208 to be processed and the tap is avoided, ensuring the quality of the workpiece 208 to be processed by the device and improving the processing efficiency.

[0050] In an embodiment of the present invention, the upper part of the base 101 is fixedly connected to the bottom end of the adjusting rod 102, the top end of the adjusting rod 102 is fixedly connected to the lower part of the protective shell 103, the outer wall of the protective shell 103 is clamped with the control grip 104, the lower part of the protective shell 103 is fixedly connected to the driver 105, the adjusting sleeve 106 is clamped outside the adjusting rod 102, the platform assembly 201 is fixedly connected to four pressure assemblies 202, and the four pressure assemblies 202 are respectively fixedly connected to two air inlet assemblies 205. Among them, two pressure assemblies 202 are respectively communicated with two adjusting assemblies 206. The inner wall of the platform assembly 201 is clamped with two rotating assemblies 203. The two rotating assemblies 203 are respectively fixedly connected to two exhaust assemblies 204. The two exhaust assemblies 204 are respectively communicated with the heat exchange assembly 207. The other end of the air inlet assembly 205 is communicated with the heat exchange assembly 207. The workpiece 208 to be processed is located inside the platform assembly 201. The heat exchange assembly 207 is fixedly connected above the base 101. One side of the platform assembly 201 is fixedly connected to the adjusting sleeve 106. During drilling, the drill bit continuously presses the workpiece 208 to be processed, so that the workpiece 208 to be processed pushes the gripper 2013 to make the first slide bar 2022 slide into the first slide sleeve 2021. At this time, the gas in the first slide sleeve 2021 will be pushed by the first piston pad 2023 and enter the second slide sleeve 2061 along the first conduit 2026, and push the second piston pad 2063 and the second slide bar 2062 to move upward. During this process, the toothed plate 2064 will push the gear 2033 to make the rotating shaft 2032 rotate. As the workpiece 208 to be processed continues to move downward, when the air in the first slide sleeve 2021 completely enters the second slide sleeve 2061, the toothed plate 2064 will disengage from the gear 2033, so that the gear 2033 returns to its original position under the elastic force of the coil spring 2034, and the air inlet cover 2051 will also move together with the gripper 2013 to ensure that during drilling, the air inlet cover 2051 can timely extract the air under the workpiece 208 to be processed and discharge the air into the heat exchange cylinder 2071. At this time, the liquid in the heat exchange cylinder 2071 will adsorb impurities and transfer heat, so that the device can dissipate heat from the workpiece 208 to be processed on the one hand during drilling, and on the other hand, during the process of dissipating heat from the workpiece, it can synchronously collect and store the metal chips generated during the drilling process, avoid wasting resources, and protect the personnel.

[0051] In an embodiment of the present invention, the platform component 201 includes a processing platform 2011. Two grooves 2012 are formed above the processing platform 2011. Two grippers 2013 are arranged above the processing platform 2011. The upper part of the processing platform 2011 is fixedly connected to the two grippers 2013 through four pressure components 202 respectively. The inner walls of the two grippers 2013 are clamped with the same processed workpiece 208. The pressure component 202 includes a first sliding sleeve 2021. A first sliding rod 2022 is slidably connected inside the first sliding sleeve 2021. The bottom end of the first sliding rod 2022 is fixedly connected to a first piston pad 2023. The first piston pad 2023 is slidably connected inside the first sliding sleeve 2021. A spring 2024 is arranged inside the first sliding sleeve 2021. The top end and the bottom end of the spring 2024 are fixedly connected to the lower part of the first piston pad 2023 and the lower part of the inner wall of the first sliding sleeve 2021 respectively. The top end of the first sliding rod 2022 is fixedly connected to a bracket 2025. The lower part of the first sliding sleeve 2021 is fixedly connected to a first conduit 2026. The first sliding sleeve 2021 is communicated with the adjusting component 206 through the first conduit 2026. The first sliding sleeve 2021 is fixedly connected above the processing platform 2011. The upper part of the bracket 2025 is fixedly connected to the gripper 2013. The other side of the bracket 2025 is fixedly connected to the air inlet component 205. The rotating component 203 includes two bearings 2031. The same rotating shaft 2032 is sleeved inside the two bearings 2031. A gear 2033 is fixedly connected to the outside of the rotating shaft 2032. Two torsion springs 2034 are sleeved outside the rotating shaft 2032. The two torsion springs 2034 are fixedly connected to the two bearings 2031 and the rotating shaft 2032 respectively. The gear 2033 is meshed with the adjusting component 206. The two bearings 2031 are both clamped on both sides of the inner wall of the same groove 2012. The rotating shaft 2032 is fixedly connected to the exhaust component 204. When tapping, since the tap does not need to continuously press the processed workpiece 208, therefore, the second sliding rod 2062 will keep the toothed plate 2064 in contact with the gear 2033. With the operation of the heater, the heater will extract external air through the spiral tube 2074, so that the liquid absorbing heat in the heat exchange cylinder 2071 preliminarily heats the air entering the spiral tube 2074, and then is injected into the exhaust shell 2041 after secondary heating by the heater. And at this time, the flipped first slide plate 2042 will push the rubber pad 2045 on the surface of the sealing plate 2044 to dock with the plug 2048, ensuring that the air can be directly injected into the first slide plate 2042 to avoid air leakage. Similarly, when the plug 2048 is not docked with the rubber pad 2045, the air will be discharged along the pressure valve 2046, avoiding a large amount of hot air being directly discharged on the surface of the processed workpiece 208 during the heat dissipation process, ensuring that the device can stably heat the processed workpiece 208 during the tapping stage, and stably dissipate heat from the processed workpiece 208 during the drilling stage, improving the stability of the device during use.

[0052] As another embodiment of the present invention, the exhaust assembly 204 includes an exhaust housing 2041. A first slide plate 2042 is fixedly connected above the exhaust housing 2041. The first slide plate 2042 is slidably connected within a second slide plate 2043. Both the first slide plate 2042 and the second slide plate 2043 are arc-shaped. The other side of the first slide plate 2042 is fixedly connected to a sealing plate 2044. A rubber pad 2045 is fixedly connected within a through hole formed outside the sealing plate 2044. The rubber pad 2045 is composed of a plurality of gaskets butt-jointed together. A pressure valve 2046 is provided outside the second slide plate 2043. A partition plate 2047 is fixedly connected within the second slide plate 2043. The partition plate 2047 is communicated with the second slide plate 2043 through a plurality of plugs 2048. The sealing plate 2044 is communicated with the first slide plate 2042 through a plurality of rubber pads 2045.

The exhaust housing 2041 is snap-fitted within the groove 2012. The second slide plate 2043 is fixedly connected within the groove 2012. The positions of the plurality of rubber pads 2045 correspond to the positions of the plurality of plugs 2048. The pressure of the rubber pad 2045 is greater than the pressure of the pressure valve 2046. The other end of the first expansion tube 2049 is communicated with the heat exchange assembly 207 through a heater. The intake assembly 205 includes an intake hood 2051. The intake hood 2051 is communicated with a second expansion tube 2052. The other end of the second expansion tube 2052 is communicated with a second conduit 2053. The second conduit 2053 is communicated with an air extractor 2054. One side of the intake hood 2051 is fixedly connected to a bracket 2025. The air extractor 2054 is communicated with the heat exchange assembly 207. When air enters the heat exchange tank 2073 along the intake groove 2072, the heat in the air is absorbed by the liquid within the heat exchange tank 2073. And since the density of the gas is less than the density of the liquid, the gas gradually floats upward, while the impurities are retained in the liquid, and the gas is discharged along the exhaust groove 2076. Similarly, when extracting gas, the gas enters the spiral tube 2074 through the intake port 2075 above the spiral tube 2074. When passing through the spiral tube 2074, the liquid heats the air within the spiral tube 2074. This device can recycle metal resources and heat resources, reducing the energy consumption of the device.

[0053] As another embodiment of the present invention, the adjusting assembly 206 includes a second sliding sleeve 2061. A second sliding rod 2062 is slidably connected inside the second sliding sleeve 2061. A second piston pad 2063 is arranged inside the second sliding sleeve 2061. The upper part of the second piston pad 2063 is fixedly connected to the bottom end of the second sliding rod 2062. The top end of the second sliding rod 2062 is fixedly connected to a toothed plate 2064. The lower part of the second sliding sleeve 2061 is fixedly connected to a mounting frame 2065. The mounting frame 2065 is fixedly connected to the processing platform 2011. The toothed plate 2064 is engaged with a gear 2033. The second sliding sleeve 2061 is communicated with the first sliding sleeve 2021 through a first conduit 2026. The heat exchange assembly 207 includes a heat exchange cylinder 2071. An air inlet groove 2072 is opened at the top end of the heat exchange cylinder 2071. A heat exchange groove 2073 is opened inside the heat exchange cylinder 2071. The heat exchange groove 2073 is communicated with the bottom of the inner wall of the air inlet groove 2072. A spiral tube 2074 is arranged inside the heat exchange groove 2073. The top end of the spiral tube 2074 is located above the heat exchange cylinder 2071. A plurality of air inlets 2075 are opened at the top end of the spiral tube 2074. A plurality of exhaust grooves 2076 are opened at the top end of the heat exchange cylinder 2071. The plurality of exhaust grooves 2076 are all communicated with the heat exchange groove 2073. The inner wall of the heat exchange groove 2073 is fixedly connected to a plurality of partition plates 2077. The first telescopic tube 2049 is communicated with the bottom end of the spiral tube 2074 through a heater. The bottom end of the air extractor 2054 is communicated with the air inlet groove 2072. The heat exchange cylinder 2071 is fixedly connected above the base 101. Since a plurality of partition plates 2077 are arranged inside the heat exchange groove 2073 and the plurality of partition plates 2077 are all processed in a staggered manner, the path of the liquid discharged inside the heat exchange groove 2073 is increased, so as to ensure that the liquid inside the heat exchange groove 2073 absorbs the heat in the air more fully and avoid the situation of resource waste.

[0054] Working principle: This embodiment provides an adjustable drilling and tapping device for a bench vice. When in use, the workpiece 208 is clamped by the gripper 2013, and a liquid is injected into the heat exchange assembly 207. After the height of the platform assembly 201 is adjusted by the adjusting sleeve 106, the adjusting sleeve 106 is fixed and the height of the drill bit is adjusted by controlling the grip 104, so as to perform drilling or tapping on the workpiece 208.

[0055] During drilling, the drill bit presses against the workpiece 208, causing the workpiece 208 to push the gripper 2013 and squeeze the pressure component 202. By pushing the internal pressure of the pressure component 202 into the adjustment component 206, at this time, the adjustment component 206 will adjust the angle of the rotating component 203. As the adjustment component 206 continues to extend, the adjustment component 206 will separate from the rotating component 203, and the rotating component 203 will reset. The air intake component 205 will continue to operate, extract the air below the workpiece 208, and discharge it into the heat exchange component 207. The liquid in the heat exchange component 207 absorbs the heat and metal impurities in the gas, completing the heat dissipation and dust collection effects during drilling. During tapping, since the tap does not require a continuously downward pressing force for the tapping step, after the tap is initially pressed into the workpiece 208, a slight pressure can be maintained to continuously tap downward. When the pressure component 202 extends the adjustment component 206 by pressure, it will adjust the angle of the exhaust component 204 through the rotating component 203. Subsequently, the exhaust component 204 will extract the air in the heat exchange component 207 through the heater, and then discharge the heated gas onto the surface of the workpiece 208, thereby heating the workpiece 208;

[0056] During drilling, the drill bit continuously presses against the workpiece 208, causing the workpiece 208 to push the gripper 2013 and the first slide rod 2022 to slide into the first slide sleeve 2021. At this time, the gas in the first slide sleeve 2021 will be pushed by the first piston pad 2023 along the first conduit 2026 into the second slide sleeve 2061, and push the second piston pad 2063 and the second slide rod 2062 upward. During this process, the toothed plate 2064 will push the gear 2033, causing the rotating shaft 2032 to rotate. As the workpiece 208 continues to move downward, when the air in the first slide sleeve 2021 completely enters the second slide sleeve 2061, the toothed plate 2064 will disengage from the gear 2033, causing the gear 2033 to reset under the elastic force of the coil spring 2034. The air intake hood 2051 will also move together with the gripper 2013 to ensure that during drilling, the air intake hood 2051 can timely extract the air below the workpiece 208 and discharge the air into the heat exchange cylinder 2071. At this time, the liquid in the heat exchange cylinder 2071 will adsorb impurities and transfer heat;

[0057] When tapping, since the tap does not need to continuously extrude and process the workpiece 208, the second sliding rod 2062 will keep the toothed plate 2064 in contact with the gear 2033. As the heater operates, the heater will extract outside air through the spiral tube 2074, so that the liquid absorbing heat in the heat exchange cylinder 2071 preliminarily heats the air entering the spiral tube 2074, and then after secondary heating by the heater, it is injected into the exhaust housing 2041. At this time, the flipped first slide plate 2042 will push the rubber pad 2045 on the surface of the sealing plate 2044 to dock with the plug 2048, ensuring that air can be directly injected into the first slide plate 2042. Similarly, when the plug 2048 is not docked with the rubber pad 2045, the air will be discharged along the pressure valve 2046.
