Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a CNC machine tool tool post structure. Background Technology

[0002] The CNC machine tool turret is a key actuator installed on the main body of a CNC machine tool. Its main function is to enable rapid tool changing and precise positioning, thereby ensuring that the machine tool can operate efficiently and continuously in multiple machining processes such as turning, milling, boring, and drilling.

[0003] Traditional CNC machine tool single-tool holders lack cooling functionality during machining, typically relying on external nozzles to spray large amounts of coolant to reduce the high temperature in the cutting area. However, this cooling method suffers from low actual cooling efficiency and persistent localized high temperatures due to the non-adjustable spray direction and excessively large spray range, preventing the coolant from being precisely concentrated on the cutting edge of the tool and the contact point with the workpiece. Furthermore, the large amount of coolant splashing and spreading not only results in significant waste and increases workshop recycling and operating costs but also creates a slippery machining environment, affecting operational safety. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a CNC machine tool tool post structure, including a support base, the support base being used to connect the three-axis moving part of the machine tool, and a clamping part provided inside the support base being connected to the output end of the machine tool's motor. A drill rod is rotatably mounted inside the support base and clamped in the clamping part. The structure also includes an input pipe, the input pipe being used to connect to a coolant supply system; an output pipe, the output pipe being used to connect to a coolant recovery and filtration system; a micro-liquid pump, which synchronously drives the micro-liquid pump to perform coolant transfer when the drill rod rotates; and a cooling channel, the cooling channel located inside the support base having both ends penetrating the input pipe and the output pipe respectively, for cooling the main body of the drill rod rotatably mounted inside the cooling channel.

[0006] In at least some embodiments, the cooling channel includes a sleeve, the sleeve including a tube body fixed inside the support, and the drill rod being rotatably mounted inside the tube body.

[0007] In at least some embodiments, a plurality of support plates fixed inside the tube body roll in contact with the drill rod, and a cooling cavity is formed between the tube body and the drill rod.

[0008] In at least some embodiments, a spiral channel is provided inside the tube body for guiding and slowly releasing coolant. The drill rod includes a screw, the upper part of which is a clamping part, and the upper part of the screw is provided with several guide grooves that communicate with the cooling cavity. In use, a portion of the coolant sprayed out from the guide grooves is directed to cool the screw part.

[0009] In at least some embodiments, a rotating rod is fixedly connected to the upper part of the screw, the rotating rod is located inside the cooling chamber, and a square rod fixed to the upper part of the rotating rod is inserted into the micro liquid pump fixed inside the support base.

[0010] In at least some embodiments, the input seat fixed to the upper part of the tube body is fixedly connected to the output end of the micro liquid pump via a transmission pipe, the input end of the micro liquid pump is fixedly connected to the input pipe, and the output seat fixed to the lower part of the tube body is fixedly connected to the output pipe.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, during actual use, the support base is stably connected to the three-axis moving part of the machine tool. The clamping part inside the support base closely cooperates with the output end of the machine tool motor, thereby achieving reliable installation and efficient rotation of the drill rod. During rotation, the drill rod not only undertakes the cutting task but also drives the linked micro-hydraulic pump to operate synchronously. When working, the micro-hydraulic pump continuously draws coolant from the input pipe and introduces it into the cooling channel inside the support base. The cooling channel is precisely arranged to fit closely with the main body of the drill rod, allowing the coolant to form a stable circumferential flow along the high-heat area of ​​the drill rod, promptly removing the large amount of heat generated by cutting friction, achieving efficient directional cooling of the drill rod, and avoiding the waste of coolant caused by large-area spraying in traditional cooling methods. After completing the cooling effect on the drill rod, the coolant is guided to the other end of the channel and quickly discharged through the output pipe into the recycling and filtration system. After treatment, it can be recycled again, thereby greatly improving the utilization rate of coolant while ensuring the cutting stability and machining accuracy of the drill rod, reducing workshop environmental pollution and liquid costs, demonstrating the working principle of high integration, energy saving and environmental protection, and high cooling efficiency of this structure.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Implementation examples, based on Figures 1-4 As shown in the figure, the present invention provides a CNC machine tool tool post structure, including a support base 1, which is used to connect the three-axis moving part of the machine tool, and a clamping part provided inside the support base 1 is connected to the output end of the machine tool motor. A drill rod 2 is rotatably mounted inside the support base 1 and clamped by the clamping part. The support base 1 also includes an input pipe 3, which is used to connect to a coolant supply system; an output pipe 4, which is used to connect to a coolant recovery and filtration system; a micro liquid pump 7, which synchronously drives the micro liquid pump 7 to perform coolant transmission when the drill rod 2 rotates; and a cooling channel, which is provided inside the support base 1 and has its two ends connected to the input pipe 3 and the output pipe 4, respectively, for cooling the main body of the drill rod 2 rotatably mounted inside the cooling channel.

[0017] In actual use, the above-mentioned CNC machine tool tool post structure is stably connected to the three-axis moving part of the machine tool through the support base 1. The clamping part set inside the support base 1 is closely matched with the output end of the machine tool motor, thereby realizing the reliable installation and efficient rotation of the drill rod 2. During the rotation, the drill rod 2 not only undertakes the cutting task, but also drives the micro liquid pump 7 linked with it to operate synchronously. When the micro liquid pump 7 is working, it continuously draws the coolant delivered from the input pipe 3 and introduces it into the cooling channel inside the support base 1. The cooling channel is precisely arranged to fit closely with the main body of the drill rod 2, so that the coolant can form a stable circumferential flow along the high heat area of ​​the drill rod 2, and promptly remove the large amount of heat generated by cutting friction, thereby achieving efficient directional cooling of the drill rod 2, while avoiding the waste of coolant caused by large-area spraying in traditional cooling methods. After cooling the drill rod 2, the coolant is guided to the other end of the channel and quickly discharged through the output pipe 4 into the recycling and filtration system. After treatment, it can be recycled again, thereby ensuring the cutting stability and machining accuracy of the drill rod 2 while greatly improving the utilization rate of the coolant and reducing workshop environmental pollution and liquid costs.

[0018] In this embodiment, the cooling channel includes a sleeve 5, which includes a tube body 501 fixed inside the support base 1. The drill rod 2 is rotatably installed inside the tube body 501. Several support plates 505 fixed inside the tube body 501 roll and fit against the drill rod 2. A cooling cavity 504 is formed between the tube body 501 and the drill rod 2. A spiral channel 506 is provided inside the tube body 501 for guiding and slowly releasing coolant. The drill rod 2 includes a screw 101. The upper part of the screw 101 is a clamping part, and several guide grooves 104 communicating with the cooling cavity 504 are provided on the upper part of the screw 101. In use, part of the coolant is sprayed out of the guide grooves 104 to guide and cool the screw 101. A rotating rod 102 is fixedly connected to the upper part of the screw 101. The rotating rod 102 is located inside the cooling cavity 504. A square rod 103 fixed to the upper part of the rotating rod 102 is inserted into a micro liquid pump 7 fixed inside the support base 1.

[0019] During operation, the drill rod 2 is connected to the output end of the machine tool motor through the clamping part and rotates at high speed. The screw 101 part at the bottom of the drill rod 2 also rotates accordingly. The cooling chamber 504 formed between the screw 101 and the tube 501 fixedly installed inside the support seat 1 becomes the main flow space of the coolant. After entering through the input pipe 3, the coolant is slowly released and transmitted along the inside of the tube 501 under the guidance of the spiral channel 506, forming a uniform surrounding flow and dissipating heat from all directions on the outer wall of the drill rod 2. Meanwhile, several support plates 505 arranged inside the tube body 501 roll and fit with the drill rod 2, which not only plays a role in stabilizing support, but also ensures that the gap of the cooling chamber 504 is constant so as to maintain smooth flow of coolant. The guide groove 104 on the upper part of the screw 101 is connected to the cooling chamber 504. When the liquid flows, some of the coolant will be sprayed out in a direction to further cover and cool the high-temperature cutting area of ​​the screw 101, effectively solving the problem of local overheating. Unlike the traditional direct coating cooling, this method is more efficient and more environmentally friendly. Meanwhile, the rotating rod 102, which is fixedly connected to the upper part of the screw 101, is located inside the cooling chamber 504. The square rod 103 mounted on its upper end is inserted into the micro liquid pump 7 inside the support base 1. When the drill rod 2 rotates, it synchronously drives the micro liquid pump 7 to operate, thereby realizing the continuous extraction and circulation of coolant. Finally, after completing the heat dissipation task, the coolant is discharged through the output pipe 4 into the recycling and filtration system for reuse. The whole working principle not only significantly improves the cooling efficiency and cutting stability of the drill rod 2, but also avoids the large amount of coolant waste under the traditional spraying method, demonstrating the technical advantages of precise liquid supply, automatic circulation and high efficiency and energy saving.

[0020] In this embodiment, the input seat 502 fixed on the upper part of the tube body 501 is fixedly connected to the output end of the micro liquid pump 7 through the transmission pipe 6, the input end of the micro liquid pump 7 is fixedly connected to the input pipe 3, and the output seat 503 fixed on the lower part of the tube body 501 is fixedly connected to the output pipe 4.

[0021] The input seat 502, fixed on the upper part of the tube body 501, is stably connected to the output end of the micro liquid pump 7 through the transmission pipe 6, so that the coolant can be delivered to the cooling chamber 504 inside the tube body 501 in a controlled manner by the liquid pump. At the same time, the input end of the micro liquid pump 7 is connected to the input pipe 3, thereby forming a closed liquid circulation path, so that the coolant continuously enters the tool holder cooling system to efficiently and directionally cool the drill rod 2 and its screw 101. After absorbing the heat generated by the cutting of the drill rod 2, the coolant flows out through the output seat 503 fixed at the bottom of the tube body 501, and is introduced into the recovery and filtration system through the connection with the output pipe 4 to realize the recycling and reuse of the liquid. The entire system achieves stable delivery, precise guidance and circulation of coolant through the orderly cooperation of the input seat 502, the liquid pump and the output seat 503. This ensures that the heat during the machining of the drill rod 2 is quickly removed, improving the machining accuracy, and significantly reduces the waste of traditional spray-type coolant, thus improving energy saving and environmental protection.

[0022] The working principle of this utility model is as follows: In actual use, the support base 1 is stably connected to the three-axis moving part of the machine tool. The clamping part set inside the support base 1 is closely matched with the output end of the machine tool motor, thereby realizing the reliable installation and efficient rotation of the drill rod 2. During the rotation, the drill rod 2 not only undertakes the cutting task, but also drives the linked micro liquid pump 7 to operate synchronously. When the micro liquid pump 7 is working, it continuously draws the coolant delivered from the input pipe 3 and introduces it into the cooling channel inside the support base 1. The cooling channel is precisely arranged to fit closely with the main body of the drill rod 2, so that the coolant can form a stable circumferential flow along the high-heat area of ​​the drill rod 2, and promptly remove the large amount of heat generated by cutting friction, thereby achieving efficient directional cooling of the drill rod 2. At the same time, it avoids the waste of coolant caused by large-area spraying in traditional cooling methods. After completing the cooling effect on the drill rod 2, the coolant is guided to the other end of the channel and quickly discharged through the output pipe 4 and enters the recycling and filtration system. After treatment, it can be recycled again, thereby ensuring the cutting stability and machining accuracy of the drill rod 2, greatly improving the utilization rate of coolant, and reducing workshop environmental pollution and liquid costs.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
