Description

Technical Field

[0001] This invention belongs to the field of machining cooling technology, specifically relating to a coolant intelligent tool-following system. Background Technology

[0002] Cutting is a common method in metal processing. During cutting, there is intense friction between the cutting tool and the workpiece. To avoid excessive temperature rise that could damage the tool and workpiece, coolant is usually injected into the cutting area to effectively reduce the temperature of the cutting zone.

[0003] Current machine tool oil spraying devices can only be manually and roughly aligned with the cutting tools. Furthermore, adjusting the coolant alignment requires repeatedly moving the spray nozzle, resulting in poor timeliness and hindering timely production. Because only a small portion of the cutting tools can be effectively sprayed, some special tools (too long or too short) cannot receive sufficient coolant during machining. This inevitably affects surface finish and can even lead to tool breakage and product scrap due to inadequate coolant spraying, increasing production costs. Summary of the Invention

[0004] The purpose of this invention is to provide a coolant-guided intelligent tool with a simple structure and reasonable design to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A coolant-following intelligent tool includes a tool holder and a tool body. The tool body is mounted on the drive end of the tool holder, and the tool holder is mounted on a tool post. The coolant-following intelligent tool further includes: The oil injection pipe is disposed on one side of the tool body, with the injection end of the oil injection pipe facing the tool body. A supply assembly is disposed on one side of the tool holder. The supply assembly includes a first supply pipe, an adjusting block, and an execution drive. The output end of the first supply pipe is rotatably connected to the adjusting block. The execution drive is mounted on the adjusting block and is used to drive the adjusting block to rotate around the axis of the first supply pipe. An oil injection pipe is fixedly connected to one side of the adjusting block. The oil injection pipe communicates with the output end of the first supply pipe through the inner cavity of the adjusting block. The rotation plane of the adjusting block coincides with the rotation axis of the tool body.

[0006] As a further optimization of the present invention, the supply assembly further includes a mounting base, a second supply pipe, a third supply pipe, and a fourth supply pipe. The input end of the first supply pipe is fixedly mounted on the mounting base, and the second supply pipe is also fixedly mounted on one side of the mounting base. The first supply pipe and the second supply pipe are connected through the inner cavity of the mounting base. The input end of the second supply pipe is connected to the third supply pipe, the input end of the third supply pipe is connected to the fourth supply pipe, the input end of the fourth supply pipe is connected to the output end of the supply pump, and the input end of the supply pump is connected to the coolant reservoir. A limiting seat is sleeved on the third supply pipe, and the limiting seat is fixedly mounted on the tool holder.

[0007] As a further optimization of the present invention, there are multiple second supply pipes, the input ends of the multiple second supply pipes are respectively connected to the second supply pipes, and the multiple second supply pipes are respectively provided with fuel injection pipes.

[0008] As a further optimization of the present invention, the fuel injection pipe includes segments, sleeve parts, and a first spring. Multiple segments are provided. A sleeve part is fixedly connected to the side of each segment facing the cutter body. The sleeve part is inserted into the through hole of an adjacent segment, and the outer peripheral surface of the sleeve part is sealed and fitted to the inner wall of the through hole of the segment. A first spring is sleeved on the outside of the sleeve part, and the two ends of the first spring are fixedly connected to the corresponding segments respectively. The first segment closest to the adjusting block is fixedly connected to the adjusting block, and the through hole of the segment communicates with the inner cavity of the adjusting block. The sleeve part on the last segment furthest from the adjusting block serves as a nozzle structure.

[0009] As a further optimization of the present invention, the segment corresponding to the nozzle structure is fixedly connected to a support plate, and the support plate has a sliding groove on the side facing the adjustment block. The other segments are slidably connected to the support plate through the sliding groove.

[0010] As a further optimization of the present invention, a limiting component is provided on one side of the pallet, and the output end of the limiting component is driven to cooperate with the pallet. The limiting component is used to adjust the extension distance of the pallet toward the tool body.

[0011] As a further optimization of the present invention, the limiting component includes a bracket, a guide rod, a second spring, a limiting rod, and a stop. The bracket is fixedly installed on the mounting base. The guide rod passes through the bracket and is slidably connected to the bracket. A limiting rod is fixedly connected to one end of the guide rod facing the support plate. The second spring is sleeved on the part of the guide rod located between the limiting rod and the bracket. The stop is fixedly installed on the upper end of the support plate. The limiting end of the limiting rod rubs against the support plate.

[0012] As a further optimization of the present invention, the third supply pipe has a circular structure and a toothed ring is installed on the third supply pipe. The toothed ring meshes with a gear, and the input end of the gear is connected to a rotating drive component, which is mounted on the tool holder.

[0013] As a further optimization of the present invention, the limiting seats are arranged in pairs, one limiting seat is slidably connected to the third supply pipe, and the other limiting seat is sleeved on the toothed ring, and the toothed ring is slidably connected to the other limiting seat.

[0014] As a further optimization of the present invention, a purging component is installed on the tool holder, and the purging end of the purging component is located on one side of the tool body.

[0015] The present invention has at least the following beneficial effects: The present invention provides a coolant intelligent following tool, including a tool holder, a tool body, an oil injection pipe and a supply assembly. The supply assembly includes a first supply pipe, an adjusting block and an execution drive component. By driving the execution drive component, the adjusting block causes the oil injection pipe to rotate and adjust to adapt to the current length of the tool body, so that the tool body can fully receive the coolant sprayed by the oil injection pipe. This effectively prevents tool breakage and scrap caused by insufficient coolant spray due to errors in manual adjustment, extends tool life, reduces production costs and improves machining efficiency. Moreover, the fuel injection pipe includes segments, sleeve parts and a first spring. Multiple segments are provided so that when coolant is injected, the foremost segment slides away from the adjusting block, causing multiple subsequent segments to move in the same direction, and the entire fuel injection pipe is stretched and extended. When coolant is not injected, under the reset action of the first spring, the segments move closer to each other, causing the overall length of the fuel injection pipe to shrink. This allows the retracted fuel injection pipe to provide more operating space when coolant injection is not needed, making the overall structure more flexible. In addition, a limiting component is provided on one side of the pallet. The limiting component includes a bracket, a guide rod, a second spring, a limiting rod, and a stop. When a longer tool body needs to be replaced, the limiting rod re-abuts and limits the pallet, thereby increasing the moving distance of the pallet. This further reduces the increase in the distance between the tool body and the nozzle structure caused by the adjustment of the oil injection pipe angle, and keeps the distance between the replaced tool body and the nozzle structure within the allowable range.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] like Figure 1 , Figure 2 As shown, the present invention provides a coolant-intelligent following tool, comprising a tool holder 2 and a tool body 3, wherein the tool body 3 is mounted on the drive end of the tool holder 2, and the tool holder 2 is mounted on a tool post 1. The coolant-intelligent following tool further includes: The oil injection pipe 5 is disposed on one side of the tool body 3, with the injection end of the oil injection pipe 5 facing the tool body 3, such as... Figure 1 As shown, the fuel injection pipe 5 is installed at an angle; Supply assembly 4 is disposed on one side of tool holder 2. Supply assembly 4 includes a first supply pipe 45, an adjusting block 46, and an execution drive 47. The output end of the first supply pipe 45 is rotatably connected to the adjusting block 46. The execution drive 47 is mounted on the adjusting block 46 and is used to drive the adjusting block 46 to rotate and adjust around the axis of the first supply pipe 45. An oil injection pipe 5 is fixedly connected to one side of the adjusting block 46. The oil injection pipe 5 communicates with the output end of the first supply pipe 45 through the inner cavity of the adjusting block 46. The rotation plane of the adjusting block 46 coincides with the rotation axis of the tool body 3.

[0020] It should be noted that this invention uses program control. The current tool body 3 number is obtained, and then the length of the current tool body 3 is obtained based on the tool body 3 number. After each tool change, the program is run and the tool length is stored in a fixed variable. The PLC then uses the tool length to determine the driving speed of the actuator 47, causing the oil injection pipe 5 to rotate to a specified angle. For example, the actuator 47 can be a servo motor or a drive motor; this is not limited here.

[0021] Driven by the actuator 47, the adjusting block 46 causes the oil injection pipe 5 to rotate and adjust to match the current length of the tool body 3. This allows the tool body 3 to fully receive the coolant sprayed from the oil injection pipe 5, effectively preventing tool breakage and scrap caused by insufficient coolant spraying due to errors in manual adjustment, thus extending tool life and improving machining efficiency.

[0022] It should be noted that existing coolants are mainly divided into two categories: water-based coolants and oil-based coolants. Oil-based coolants are based on mineral oil or synthetic oil. For example, mineral oil-based cutting oils are directly blended from mineral oil; extreme pressure cutting oils are made by adding extreme pressure additives such as sulfur, phosphorus, and chlorine to mineral oil. They can be selected according to the physical and chemical properties of the tool body and the workpiece, and no restrictions are imposed here.

[0023] For example, see below. Figure 1 and Figure 2The supply assembly 4 also includes a mounting base 44, a second supply pipe 43, a third supply pipe 42, and a fourth supply pipe 41. The input end of the first supply pipe 45 is fixedly mounted on the mounting base 44. The second supply pipe 43 is also fixedly mounted on one side of the mounting base 44. The first supply pipe 45 and the second supply pipe 43 are connected through the inner cavity of the mounting base 44. The input end of the second supply pipe 43 is connected to the third supply pipe 42. The input end of the third supply pipe 42 is connected to the fourth supply pipe 41. The input end of the fourth supply pipe 41 is connected to the output end of the supply pump. The input end of the supply pump is connected to the coolant reservoir. A limiting seat 48 is sleeved on the third supply pipe 42, and the limiting seat 48 is fixedly mounted on the tool holder 1. The supply pump delivers the coolant in the coolant reservoir sequentially through the fourth supply pipe 41, the third supply pipe 42, the second supply pipe 43, and the first supply pipe 45 to the fuel injection pipe 5.

[0024] For example, see below. Figure 4 and Figure 5 The oil injection pipe 5 includes a segment 51, a sleeve part 511, and a first spring 52. Multiple segments 51 are provided. The sleeve part 511 is fixedly connected to the side of the segment 51 facing the tool body 3. The sleeve part 511 is inserted into the through hole of the adjacent segment 51, and the outer peripheral surface of the sleeve part 511 is sealed and fitted with the inner wall of the through hole of the segment 51. The first spring 52 is sleeved on the outside of the sleeve part 511. The two ends of the first spring 52 are fixedly connected to the corresponding segments 51. The first segment 51 near the adjusting block 46 is fixedly connected to the adjusting block 46, and the through hole of the segment 51 communicates with the inner cavity of the adjusting block 46. The sleeve part 511 on the last segment 51 away from the adjusting block 46 serves as a nozzle structure.

[0025] like Figure 4 As shown, the oil injection pipe 5 is in its initial position, i.e., when it is not extended. At this time, there is no need to spray coolant onto the tool body 3. When coolant needs to be supplied, under the pressure of the coolant, the foremost segment 51 slides away from the adjusting block 46, and the first spring 52 is stretched, causing multiple segments 51 behind to move in the same direction. At this time, the oil injection pipe 5 is stretched and extended as a whole, so that when coolant spraying is not needed, the retracted oil injection pipe 5 provides more operating space, such as for replacing and adjusting the tool body 3, installing the workpiece, etc., making the overall structure more flexible.

[0026] Among them, such as Figure 4 As shown, the segment 51 corresponding to the nozzle structure is fixedly connected to a support plate 53. The support plate 53 has a groove on the side facing the adjusting block 46, and the other segments 51 are slidably connected to the support plate 53 through the grooves. The support plate 53 supports the segments 51, ensuring the stability of the segment 51's expansion and contraction.

[0027] Furthermore, continue to refer to Figure 1 and Figure 4 A limiting component 6 is provided on one side of the support plate 53. The output end of the limiting component 6 is in transmission cooperation with the support plate 53. The limiting component 6 is used to adjust the extension distance of the support plate 53 toward the tool body 3.

[0028] For example, see below. Figure 4 and Figure 6 The limiting component 6 includes a bracket 61, a guide rod 62, a second spring 63, a limiting rod 64, and a stop 65. The bracket 61 is fixedly installed on the mounting base 44. The guide rod 62 passes through the bracket 61 and is slidably connected to the bracket 61. The end of the guide rod 62 facing the support plate 53 is fixedly connected to the limiting rod 64. The portion of the guide rod 62 located between the limiting rod 64 and the bracket 61 is fitted with the second spring 63. The stop 65 is fixedly installed on the upper end of the support plate 53. The limiting end of the limiting rod 64 rubs against the support plate 53.

[0029] In the above embodiments, it should be noted that the position of the fuel injection pipe 5 indicated by the upper dotted line corresponds to the shortest tool body 3. When a longer tool body 3 needs to be replaced, the tilt angle of the fuel injection pipe 5 is changed by controlling the actuator 47, such as... Figure 6 As shown, the inclination direction of the fuel injection pipe 5 rotates counterclockwise from the position indicated by the upper dotted line to the position indicated by the lower dotted line, that is, the fuel injection pipe 5 and the limiting assembly 6 are in the swing angle position. At this time, the support plate 53 presses the limiting rod 64, and the second spring 63 is further compressed. Then, under the spray of coolant, the last segment 51 away from the adjusting block 46 drives the support plate 53 to move towards the position indicated by the lower dotted line. The movement of the support plate 53 is terminated by the contact and limiting of the stop block 65 and the limiting rod 64. That is, at this time, the extension length of the fuel injection pipe 5 is limited, and the moving distance of the support plate 53 is a. During the process of the inclination direction of the fuel injection pipe 5 rotating counterclockwise from the position indicated by the upper dotted line to the position indicated by the lower dotted line, the moving distance a of the support plate 53 also increases, thereby further reducing the degree of increase in the distance between the tool body 3 and the nozzle structure caused by the angle adjustment of the fuel injection pipe 5, so that the distance between the replaced tool body 3 and the nozzle structure is controlled within the allowable range. This prevents the distance between the tool body 3 and the nozzle structure from being too large, which would cause the coolant to experience pressure drop and flow rate reduction when it reaches the tool body 3, making it unable to effectively penetrate the cutting area. This would also significantly reduce the cooling and lubrication effects, and cause severe coolant splashing due to the unconcentrated coolant spray, increasing waste. At the same time, it would be difficult to form a stable lubricating film, exacerbating the friction and wear between the tool body 3 and the workpiece.

[0030] For example, see below. Figure 2 , Figure 7 and Figure 8The third supply pipe 42 has a circular structure and a gear ring 49 is mounted on it. The gear ring 49 meshes with a gear 410, and the input end of the gear 410 is connected to a rotation drive component, which is mounted on the tool holder 1. For example, the rotation drive component is a drive motor. Under the drive of the drive motor, the gear 410 meshes with the gear ring 49, causing the third supply pipe 42 to rotate, thereby changing the position of the oil injection pipe 5 on the circumference of the tool body 3. It should be noted that because the rotation of the third supply pipe 42 causes a circumferential change in the connection position between the fourth supply pipe 41 and the third supply pipe 42, the fourth supply pipe 41 can be configured as a spiral flexible hose to accommodate the distance between the input end of the fourth supply pipe 41 and the input end of the third supply pipe 42.

[0031] Among them, such as Figure 8 As shown, the limiting seats 48 are arranged in pairs. One limiting seat 48 is slidably connected to the third supply pipe 42, and the other limiting seat 48 is sleeved on the toothed ring 49. The toothed ring 49 is slidably connected to the other limiting seat 48 to ensure that the other limiting seat 48 constrains and supports the meshing rotation trajectory of the toothed ring 49.

[0032] For example, multiple second supply pipes 43 are provided, with the input ends of each second supply pipe 43 connected to the second supply pipe 43, and each second supply pipe 43 is correspondingly provided with an oil injection pipe 5. That is, multiple oil injection pipes 5 are distributed around the tool body 3, which can spray coolant from multiple angles and improve the cooling efficiency of the tool body 3.

[0033] It should be noted that, as Figure 1 As shown, a blower 7 is installed on the tool holder 1. The blower end of the blower 7 is located on one side of the tool body 3. When the tool body 3 is being machined, if the coolant is not required to be sprayed, the cutting chips can be blown away by the blower 7.

[0034] It should be noted that the coolant intelligently follows the tool. When in use, the coolant supply stops. At this time, under the elastic force of the first spring 52, multiple sections 51 are contracted together to shorten the length of the oil injection pipe 5 as a whole. This makes it convenient for the staff to replace the tool body 3. Then, based on the length of the replaced tool body 3, the drive actuator 47 is driven to cause the adjusting block 46 to deflect the oil injection pipe 5 so that the coolant is sprayed toward the tool body 3. Under the drive of the supply pump, the coolant is delivered to the oil injection pipe 5 and sprayed onto the tool body 3 by the nozzle. At this time, the sprayed coolant drives multiple segments 51 to move, which, compared to the oil injection pipe 5 in the contracted state, ultimately achieves the overall length extension of the oil injection pipe 5. Furthermore, when adjusting the tilt angle of the fuel injector 5, for example, Figure 6 As shown, the tilt direction of the oil injection pipe 5 rotates counterclockwise from the position indicated by the upper dotted line to the position indicated by the lower dotted line. The support plate 53 presses against the limiting rod 64, and the second spring 63 is further compressed. At this time, under the spray of coolant, the oil injection pipe 5 extends, which increases the moving distance a value of the support plate 53, thereby further reducing the degree of increase in the distance between the tool body 3 and the nozzle structure caused by the angle adjustment of the oil injection pipe 5. Furthermore, driven by the rotating drive, the gear 410 meshes with the gear ring 49, causing the third supply pipe 42 to rotate around the rotation axis of the tool body 3, so as to adjust the position of the oil injection pipe 5 on the periphery of the tool body 3.

[0035] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
