Description

Technical Field

[0001] The invention relates to the technical field of wheel production equipment, in particular to a wheel production milling device. Background Art

[0002] During the milling process of wheel production, a large amount of heat is generated in the cutting area. If it is not cooled in time, the temperature of the milling cutter and the workpiece surface will rise rapidly, which may cause increased wear of the milling cutter, burns on the workpiece surface, and even affect the processing accuracy. In order to reduce the temperature of the processing area, cutting fluid is usually used for cooling and lubrication. In the prior art, the cutting fluid is sprayed into the processing area through a cooling pipe, and the cooling pipe is usually equipped with a fixed-caliber nozzle, which keeps the flow rate and flow velocity of the cutting fluid constant throughout the entire processing process.

[0003] However, this constant spraying method has obvious drawbacks. When the area to be processed is small, the amount of cutting fluid sprayed often far exceeds the actual demand, resulting in a waste of resources. In addition, excessive spraying of cutting fluid may also cause too much coolant to adhere to the surface of the workpiece, thereby affecting subsequent processing steps and even causing environmental problems. For example, excessive overflow and loss of cutting fluid not only increases the difficulty of cleaning, but also poses potential hazards to the workshop environment and the health of operators.

[0004] On the other hand, when the area to be milled is large, the cutting fluid sprayed by the fixed nozzle cannot completely cover the entire processing surface, which may cause insufficient cooling in some areas. This uneven cooling effect will cause quality problems on the processed surface, such as local overheating, deformation, and even cracking, which directly affects the processing accuracy and product quality of the wheel. Therefore, the existing cooling system is difficult to adapt to the needs of processing areas of different sizes and shapes, and cannot flexibly adjust the spray flow and coverage of the coolant, which limits the working efficiency and processing quality of the equipment.

[0005] Based on the above problems, the existing technology still lacks an effective solution that can automatically adjust the coolant injection flow rate according to the size of the processing area. Although the use of cutting fluid can be optimized by manual adjustment or adding control systems such as sensors, these methods are complex and costly, easily increase the equipment failure rate, and operation and maintenance are more cumbersome. Summary of the invention

[0006] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a wheel production milling processing device to realize automatic adjustment of the cutting fluid injection amount, avoid the problems of cutting fluid waste and insufficient cooling effect, and improve the working efficiency and cooling effect of the equipment.

[0007] To achieve the above object, the present invention adopts the following technical solution:

[0008] A wheel production milling device includes a CNC milling machine, a cooling pipe is installed on the CNC milling machine, and a nozzle module is installed at the front end of the cooling pipe; the nozzle module includes:

[0014] The transmission assembly is configured with multiple ends, one end of which is mounted on the first vertical pole and the other end is mounted on the second vertical pole, and is in frictional contact with the inner side of the rubber sleeve; when the rotating cylinder rotates, the transmission assembly controls the change in the diameter of the end of the rubber sleeve away from the cooling pipe.

[0015] Preferably, the transmission assembly includes a transmission plate and a support rod; one end of the transmission plate is provided with a mounting hole adapted to the second vertical pole, and the other end is provided with a guide hole adapted to the second vertical pole; the transmission plate is rotatably mounted on the second vertical pole through the mounting hole; the first vertical pole is slidably passed through the guide hole; one end of the support rod is fixed to one end of the transmission plate close to the guide hole, and the other end is in frictional contact with the inner side surface of the rubber sleeve.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The device of the present invention is designed with a nozzle module with an adjustable function, which can dynamically adjust the injection flow and coverage of the cutting fluid according to the actual milling processing area. When the processing area is small, the nozzle module can reduce the injection amount by adjusting the diameter of the rubber sleeve to prevent excessive waste of cutting fluid and save resources; when the processing area is large, the nozzle module can expand the injection area of ​​the cutting fluid to ensure that the cutting fluid covers the entire processing surface and avoid insufficient cooling in local areas. Through this automatic adjustment mechanism, the device can adapt to wheel milling tasks of different sizes and complex shapes, ensuring the rational use of cutting fluid during the processing process.

[0023] In addition, by using the structural change of the rubber sleeve to adjust the injection flow of the cutting fluid, the present invention avoids the traditional switch valve or complex flow control system. This design not only reduces the wear of parts, but also further reduces the energy consumption and noise of the device, making it more environmentally friendly and economical in actual use. In the long-term continuous processing process, the present device can significantly reduce the waste of cutting fluid, reduce operating costs, and meet the needs of industrial production for high efficiency and energy saving.

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] like Figures 1 to 7 As shown, a wheel production milling device includes a CNC milling machine 1, a cooling pipe 2 is installed on the CNC milling machine 1, and a nozzle module 3 is installed at the front end of the cooling pipe 2. The nozzle module 3 is used to adjust the injection amount and coverage area of ​​the cutting fluid to adapt to milling processing areas of different sizes, ensure that the cutting fluid can accurately cover the processing surface, and improve the cooling effect.

[0035] The nozzle module 3 includes the following main components:

[0036] The sleeve 31 is sleeved and mounted on the cooling pipe 2, and a plurality of first vertical rods 311 are fixedly arranged at the front end thereof. The first vertical rods 311 are distributed in a circular array around the axis of the sleeve 31. This structure can not only ensure the diversification of the spray direction of the coolant, but also improve the uniformity of the coolant coverage area. The first vertical rods 311 are usually made of high-strength materials, have strong impact resistance and corrosion resistance, and are suitable for stability requirements in long-term working environments.

[0037] The rotating cylinder 33 is rotatably mounted on the sleeve 31, and a plurality of second vertical rods 39 adapted to the first vertical rods 311 are fixedly arranged on the front end surface of the rotating cylinder 33. The arrangement of the second vertical rods 39 matches the first vertical rods 311 to ensure that the entire nozzle module 3 can be effectively driven to adjust during rotation. The rear end of the rotating cylinder 33 is sleeved with a gear ring 310, which cooperates with the subsequent drive assembly to drive the rotating cylinder 33 to rotate by rotating the gear ring 310, thereby adjusting the injection angle and range of the cutting fluid. The outer surface of the rotating cylinder 33 is precisely processed to ensure that it can rotate smoothly in the sleeve 31, reduce friction and wear, and increase the service life of the device.

[0038] The drive assembly is fixed on the sleeve 31 and is mainly used to drive the ring gear 310 to rotate. The drive assembly generally includes a motor 37, a gear 36 and other transmission elements. The output shaft of the motor 37 is equipped with a gear 36, which meshes with the ring gear 310 on the rotating cylinder 33. The motor 37 drives the gear 36 to rotate, thereby realizing the rotation of the rotating cylinder 33. The motor 37 can accurately control the rotation angle and speed of the rotating cylinder 33 through the design of the transmission mode, ensuring that the amount of cutting fluid spray matches the processing area.

[0039] The positioning cylinder 32 is sleeved on the outside of the rotating cylinder 33 and is used to fix one end of the rotating cylinder 33 and keep it in a predetermined position. One end of the positioning cylinder 32 is fixedly connected to the sleeve 31, which can provide stable support when the rotating cylinder 33 rotates. The positioning cylinder 32 is made of thicker material to enhance its shock resistance and durability, and prevent the rotating cylinder 33 from deflecting due to vibration or external force during operation.

[0040] One end of the rubber sleeve 34 is sleeved on the positioning cylinder 32 and fixedly connected to the positioning cylinder 32. The diameter of the rubber sleeve 34 gradually decreases from the end close to the cooling tube 2 to the end away from the cooling tube 2. This conical design can effectively guide the flow of the cutting fluid and control the injection amount by changing the diameter. When the rotating cylinder 33 drives the transmission component to operate, the diameter of the rubber sleeve 34 will expand or shrink as needed, thereby controlling the injection flow of the cutting fluid. The rubber sleeve 34 is made of high temperature resistant and corrosion resistant materials, which can maintain its shape and function in a long-term industrial environment and avoid affecting its service life due to high temperature or chemical corrosion.

[0041] The transmission assembly is provided with a plurality of transmission assemblies, which are respectively installed between the first vertical rod 311 and the second vertical rod 39, and are used to convert the rotational motion of the rotating cylinder 33 into the radial change of the rubber sleeve 34. The transmission assembly is in frictional contact with the inner side of the rubber sleeve 34. When the rotating cylinder 33 rotates, the transmission assembly controls the diameter change of the end of the rubber sleeve 34 away from the cooling pipe 2, thereby adjusting the injection flow of the cutting fluid. The transmission assembly includes a transmission plate 38 and a support rod 35.

[0042] In this embodiment, a mounting hole 382 adapted to the second vertical rod 39 is provided at one end of the transmission plate 38 in the transmission assembly, and a guide hole 381 adapted to the second vertical rod 39 is provided at the other end. The transmission plate 38 is rotatably mounted on the second vertical rod 39 through the mounting hole 382, ​​and the first vertical rod 311 can slide through the guide hole 381. This sliding structure design ensures that the transmission plate 38 can smoothly follow the movement of the rotating cylinder 33 when rotating, and at the same time ensures that it maintains stability during the processing. The material of the transmission plate 38 is a lightweight and high-strength alloy material, which can reduce energy loss during rotation and improve work efficiency while ensuring the stability of the device.

[0043] One end of the support rod 35 is fixed to one end of the transmission plate 38 near the guide hole 381, and the other end is in frictional contact with the inner side of the rubber sleeve 34. The main function of the support rod 35 is to transmit the movement of the transmission plate 38 to the rubber sleeve 34 and adjust the diameter of the rubber sleeve 34 through friction. The support rod 35 is made of wear-resistant material, which can effectively reduce friction and ensure the stability and accuracy of the device during long-term operation.

[0044] In this embodiment, a connecting plate 352 is fixedly provided at one end of the support rod 35. The main function of the connecting plate 352 is to make the force transmission between the support rod 35 and the transmission plate 38 more stable and prevent the support rod 35 from deforming or falling off during operation. The material of the connecting plate 352 is selected from a high-hardness material to enhance its fatigue resistance and ensure that it can still maintain high efficiency in multiple reciprocating motions.

[0045] In addition, a ball head 351 is fixedly provided on one end of the support rod 35 away from the transmission plate 38, and the ball head 351 is in frictional contact with the inner side of the rubber sleeve 34. The design of the ball head 351 can reduce the friction surface and the friction coefficient through point contact between the ball and the rubber sleeve 34, thereby extending the service life of the rubber sleeve 34 and the support rod 35. The ball head 351 is made of high temperature resistant and wear resistant materials to ensure that it can maintain stability in high-speed rotation and high temperature environment.

[0046] The driving assembly also includes a motor 37 and a gear 36. The motor 37 is mounted on the sleeve 31, and the gear 36 on the output shaft of the motor 37 meshes with the ring gear 310 on the rotating cylinder 33. The motor 37 drives the gear 36, and the rotating cylinder 33 achieves precise rotation, thereby effectively controlling the expansion or contraction of the rubber sleeve 34, and then adjusting the injection flow and coverage of the cutting fluid.

[0047] In this embodiment, in order to ensure the normal operation of the transmission assembly and the gear 36, an opening for accommodating the gear 36 is provided on the positioning cylinder 32. The opening ensures that the gear 36 can mesh smoothly with the gear ring 310, and also facilitates the subsequent maintenance and repair of the equipment.

[0048] How it works

[0049] The core principle of the wheel production milling device is to control the injection amount and injection angle of the cutting fluid by rotating and adjusting the diameter of the rubber sleeve 34 of the nozzle module 3. Specifically:

[0050] When the device is started, the motor 37 drives the rotating cylinder 33 to rotate through the meshing of the gear 36 and the gear ring 310 , and the rotation of the rotating cylinder 33 causes the second vertical rod 39 connected thereto to rotate synchronously.

[0051] The rotation of the rotating cylinder 33 is transmitted through the transmission plate 38 connected to the first vertical rod 311. The transmission plate 38 rotates around the axis of the second vertical rod 39, and the first vertical rod 311 slides in the guide hole 381 to ensure the smooth rotation of the transmission plate 38.

[0052] When the transmission plate 38 rotates, the support rod 35 thereon moves accordingly, and the support rod 35 contacts the inner side surface of the rubber sleeve 34. The movement of the support rod 35 pushes or pulls the inner wall of the rubber sleeve 34, causing the rubber sleeve 34 to move away from or close to one end of the cooling pipe 2, thereby changing the diameter of the end of the rubber sleeve 34.

[0053] As the diameter of the rubber sleeve 34 changes, the amount and range of the cutting fluid sprayed will also be adjusted accordingly. When the diameter of the rubber sleeve 34 decreases, the amount of cutting fluid sprayed decreases, which is suitable for milling of a smaller area; when the diameter of the rubber sleeve 34 increases, the amount of spraying increases, covering a larger area, meeting the cooling needs of large-area milling.

[0054] This design can achieve precise control of the cutting fluid in different processing areas, avoid the problem of fixed water output of the traditional cooling pipe 2, reduce energy waste, and ensure that the cutting fluid can cover the entire processing surface during large-area processing, thereby improving the cooling effect.

[0055] How to use

[0056] Preparation:

[0057] First, the workpiece to be milled is fixed on the CNC milling machine 1, and the processing parameters of the milling machine are set according to the milling requirements.

[0058] Confirm that the cooling pipe 2, nozzle module 3 and rotating mechanism are connected normally, and ensure that there are no abnormalities in the driving components such as the motor 37 and gear 36.

[0059] Start the device:

[0060] Start the CNC milling machine 1 and turn on the cooling system.

[0061] After the motor 37 is started, it drives the rotating cylinder 33 of the nozzle module 3 to start working, and the transmission component rotates with the rotating cylinder 33 to gradually adjust the diameter of the rubber sleeve 34.

[0062] Cutting fluid adjustment:

[0063] During the milling process, the system automatically adjusts the diameter of the rubber sleeve 34 according to the size of the area to be processed. When the processing area is small, the diameter of the rubber sleeve 34 is reduced and the amount of cutting fluid sprayed is reduced to avoid cutting fluid waste; when the processing area is large, the diameter of the rubber sleeve 34 is increased and the amount of cutting fluid sprayed is increased to ensure that sufficient coolant covers the processing surface.

[0064] The speed of the motor 37 can be manually adjusted or the rotation of the motor 37 can be stopped on the operation panel to adjust the rotation speed of the nozzle module 3 and the amount of cutting fluid sprayed.

[0065] Processing:

[0066] As the milling process progresses, cutting fluid is continuously sprayed onto the machining surface to keep the workpiece cool and avoid overheating. The system automatically adjusts the spray volume and coverage according to the machining area to ensure optimal cooling effect.

[0067] When processing a large-area workpiece, the diameter of the rubber sleeve 34 will be enlarged, and the injection volume will increase, so that the entire processing surface can be completely covered to ensure uniform cooling.

[0068] Shutdown and Maintenance:

[0069] After the processing is completed, the motor 37 and the milling machine are stopped and the cooling system is turned off.

[0070] Check the cooling pipe 2 and the nozzle module 3, clean the remaining cutting fluid and chips, and ensure that the device remains clean and functions normally when used next time.

[0071] Check the gear 36, the gear ring 310 and the transmission components for wear regularly, and lubricate and replace them when necessary.

[0072] Through this device, users can efficiently control the flow rate and coverage area of ​​the cutting fluid to ensure the best cooling effect during the milling process, improve processing efficiency and reduce energy waste.
