Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, specifically to a milling device for processing faucets. Background Technology

[0002] As the kitchen and bathroom hardware industry continues to demand higher precision in product appearance and processing efficiency, the stability of tool clamping in faucet milling is receiving increasing attention. Faucets, as core components of kitchen and bathroom hardware, are mostly made of copper alloys and stainless steel. Milling is a crucial process for shaping the faucet's form and machining its holes, and the stability of the milling cutter clamping directly determines processing accuracy and production safety. Existing milling equipment for faucet processing generally uses a manual locking mechanism with a tapered chuck and a clamping cap, relying on the mechanical pressure generated by tightening the threads to hold the milling cutter shank and secure the tool.

[0003] This type of clamping structure can only provide a constant static clamping force and cannot automatically adjust the clamping force according to changes in machining conditions. During high-speed cutting of the workpiece by the milling cutter, the continuous friction between the cutting edge and the metal workpiece generates a large amount of cutting heat. The heat is conducted along the tool holder to the tapered collet and collet seat, causing the metal clamping components to expand and deform due to heat. The initially set clamping force continuously decreases as the temperature rises. During long-term continuous high-speed machining, the thermal expansion of the tool continues to increase, and the fit clearance of the clamping interface changes. This easily leads to problems such as milling cutter loosening and slippage, and excessive radial runout, resulting in increased surface roughness of the faucet, deviation of dimensional accuracy from design requirements, and directly increasing the product scrap rate. Summary of the Invention

[0004] This invention provides a milling device for faucet processing, which can adaptively adjust the clamping force according to the temperature change of the milling cutter itself.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: In a first aspect, a milling device for processing faucets includes: a base and a frame disposed on the base, and further includes: Adjusting components are fixed to the base and frame; the work box is fixed above the adjusting components and located on the frame; the function box is fixed to the work box; the power component is fixed inside the work box; the mounting cylinder is rotatably inserted into the bottom of the work box; the clamping seat is rotatably positioned below the mounting cylinder; sixteen sets of temperature compensation components are provided, and the sixteen sets of temperature compensation components are distributed at equal angles around the clamping seat as the axis within the clamping seat; the conical clamping cylinder is slidably inserted into the bottom of the clamping seat; the clamping cap is threaded onto the bottom of the clamping seat; and the worktable is fixed below the adjusting components and located at the base.

[0007] Furthermore, the adjusting member includes: There are two first guide rails, each bolted to the frame; four first sliders, each pair slidably mounted on two first guide rails; a first displacement plate, bolted on one side to the first slider and on the other side to the work box; a first motor base, fixed to the frame; a first drive motor, fixed to the first motor base; a first lead screw, one end fixed to the first drive motor and the other end rotatably mounted below the frame and oriented vertically; and a first nut seat, fixed to the first displacement plate and threaded onto the first lead screw.

[0008] Furthermore, the adjusting member also includes: There are two second guide rails, each fixed to one side of the base; there are four second sliders, each pair sliding on two second guide rails; a second displacement plate is fixed to the second sliders with screws; a second motor base is fixed to the rear end of the base; a second drive motor is fixed to the second motor base; a second lead screw has one end fixed to the second drive motor and the other end rotatably mounted at the front end of the base, and is positioned in a front-rear direction; a second nut seat is fixed to the second displacement plate and threaded onto the second lead screw.

[0012] Furthermore, the power component also includes: The power motor is fixed above the mounting bracket; the first power gear is fixed on the power motor; the power shaft is rotatably inserted into the mounting cylinder, and one end of the shaft inside the mounting cylinder is connected to the clamp seat; the second power gear is fixed above the power shaft; the synchronous belt has one end fitted onto the first power gear and the other end fitted onto the second power gear.

[0013] Furthermore, the end face of the curved block is provided with an anti-slip groove.

[0014] Furthermore, it also includes: The function knob is located at the front of the function box; the first handle is located at the front of the work box; the second handle is located at the front of the work box.

[0015] The above-described solution of the present invention has at least the following beneficial effects: This invention utilizes a milling cutter to continuously generate heat during the cutting of a faucet workpiece. The milling cutter's own temperature gradually increases, and this heat is transferred to a tapered collet, which in turn transfers heat to a heat-conducting plate. The heat-conducting plate then conducts the heat to the temperature-sensing cavity inside the temperature-sensing box, causing the temperature inside the cavity to rise synchronously. This temperature action acts on a shape memory alloy spring, causing it to deform and contract upon heating. The resulting tension drives a ring seat downwards, which in turn drives a guide rod and an extension rod to slide downwards simultaneously. The guide rod pulls an elastic piston downwards along the movable cavity, and the extension rod drives a first hydraulic piston downwards within the hydraulic cavity. The first hydraulic piston compresses the hydraulic oil inside the hydraulic cavity, forcing it to be transported through a supply pipe to the hydraulic cylinder, which is fixedly installed inside the hydraulic tank. As the amount of hydraulic oil inside the hydraulic cylinder increases, it pushes a second hydraulic piston outwards, which in turn drives a pressure rod. As the chuck moves towards the conical chuck, the pressure rod pushes the slanted block out of the groove. The limiting blocks on the upper and lower sides of the slanted block slide along the limiting groove, limiting the movement path of the slanted block and ensuring stable movement without deviation. The inclined surface of the slanted block abuts against the conical surface of the conical chuck, applying a thrust towards the clamping cap. The movement of the conical chuck is restricted by the clamping cap. The slanted block and the clamping cap together form an additional clamping force on the conical chuck. The faster the milling cutter rotates, the higher the heat generated by cutting, the greater the contraction of the shape memory alloy spring, and the greater the thrust output of the hydraulic transmission. The greater the force with which the slanted block and the clamping cap clamp the conical chuck and the milling cutter, the higher the stability of the milling cutter's rotation. The device can adaptively adjust the clamping force according to the temperature change of the milling cutter itself. The higher the temperature, the tighter the clamping, preventing loosening and slippage of the milling cutter during high-speed machining, and ensuring machining safety and accuracy.

The first displacement plate 303 slides along the first guide rail 301 through the first slider 302 to ensure that the movement is smooth and does not deviate. When the first displacement plate 303 moves, it synchronously drives the work box 4, mounting cylinder 7, clamping cylinder seat 8, conical clamping cylinder 10 and clamping cap 11 to move upward or downward as a whole, adjusting the height position of the milling operation to adapt to different processing requirements. The first motor seat 304 provides a fixed support for the first drive motor 305 to ensure stable operation of the motor.

[0033] The second drive motor 3012 is started, which drives the second lead screw 3013 to rotate. The rotation of the lead screw 3013 causes the second nut seat 3014 to move in the front-back direction. The second nut seat 3014 drives the second displacement plate 3010 to move synchronously. The second displacement plate 3010 slides along the second guide rail 308 via the second slider 309, ensuring smooth and stable front-back movement. This adjusts the front-back position of the worktable 12 to match different milling machining positions. The second motor seat 3011 provides a fixed support for the second drive motor 3012, ensuring stable motor operation.

[0034] The third drive motor 3018 is started, which drives the first transmission gear 3019 to rotate. The first transmission gear 3019 drives the second transmission gear 3020 to rotate synchronously through the transmission belt 3021. The second transmission gear 3020 drives the third lead screw 3022 to rotate. The rotation of the third lead screw 3022 drives the third nut seat 3023 to move in the left and right directions. The third nut seat 3023 drives the worktable 12 to move synchronously. The worktable 12 slides along the third guide rail 3015 through the third slider 3016 to ensure smooth and precise left and right movement. This adjusts the left and right position of the worktable 12, which works in conjunction with the clamping sleeve seat 8, the conical clamping sleeve 10, and the clamping cap 11 to complete the milling operation. The third motor seat 3017 provides a mounting and fixing support for the third drive motor 3018. The dust cover 3024 is placed on the outside of the transmission components to prevent machining debris and dust from entering the transmission structure and ensure smooth transmission.

[0035] The power motor 604 is started, which drives the first power gear 605 to rotate. The first power gear 605 drives the second power gear 607 to rotate synchronously via the synchronous belt 608. The second power gear 607 drives the power shaft 606 to rotate. The rotation of the power shaft 606 drives the chuck seat 8 to rotate synchronously. The chuck seat 8 drives the tapered chuck 10 and the clamping cap 11 to rotate together, ultimately driving the milling cutter clamped in the tapered chuck 10 to rotate, outputting the rotational power required for milling. The intermediate plate 601 and the mounting bracket 602 provide mounting support for the power components, and the sleeve seat 603 forms a rotational support for the mounting cylinder 7, ensuring stability during rotation.

[0036] Function knob 13 is provided on function box 5 to start the corresponding processing function of the device; rotating the first handle 14 and the second handle 15 can adjust the corresponding power supply parameters of the device; when clamping the milling cutter, first loosen the clamping cap 11 from the collet seat 8, then put the tail end of the milling cutter into the tapered collet 10, and finally tighten the clamping cap 11. Through the threaded engagement between the collet seat 8 and the clamping cap 11, the tapered collet 10 is squeezed inward to produce a contraction deformation, which firmly fixes the milling cutter inside the tapered collet 10, thus completing the preparation work for clamping the milling cutter.

[0037] During continuous processing, the milling cutter generates heat as it cuts the faucet workpiece. The milling cutter's temperature gradually rises, and this heat is transferred to the tapered chuck 10, which in turn transfers it to the heat-conducting plate 908. The heat-conducting plate 908 then conducts the heat to the temperature-sensing cavity 907 inside the temperature-sensing box 905, causing the temperature inside the temperature-sensing cavity 907 to rise synchronously. The temperature-sensing box 905 is fixedly installed inside the temperature-sensing groove 901 to ensure a stable heat conduction path. The temperature acts on the shape memory alloy spring 9014, causing it to deform and contract upon heating. The resulting tension drives the ring seat 9013 downwards. The ring seat 9013 then drives the guide rod 9012 and the extension rod 9016 to slide downwards simultaneously. The guide rod 9012 pulls the elastic piston 9010 downwards along the movable cavity 906, compressing the return spring 9011 and storing the return force. The extension rod 9016 drives the first hydraulic piston 9015 to move downward in the hydraulic chamber 909. The first hydraulic piston 9015 squeezes the hydraulic oil inside the hydraulic chamber 909, so that the hydraulic oil is delivered to the hydraulic cylinder 9017 through the supply pipe 9018. The hydraulic cylinder 9017 is fixedly installed inside the hydraulic tank 902.

[0038] After the hydraulic oil inside the hydraulic cylinder 9017 increases, it pushes the second hydraulic piston 9019 to move outward. The second hydraulic piston 9019 drives the pressure rod 9020 to move towards the cone clamp 10. The pressure rod 9020 pushes the curved block 9021 to extend out of the inclined groove 903. The limiting blocks 9022 on the upper and lower sides of the curved block 9021 slide along the limiting groove 904, limiting the movement path of the curved block 9021 and ensuring that the movement direction is stable and does not deviate. The inclined surface of the curved block 9021 abuts against the conical surface of the cone clamp 10. A thrust is applied to the tapered collet 10 in the direction of the clamping cap 11. The movement of the tapered collet 10 is restricted by the clamping cap 11. The slant block 9021 and the clamping cap 11 together form an additional clamping force on the tapered collet 10. The faster the milling cutter rotates, the higher the heat generated by cutting, the greater the contraction of the shape memory alloy spring 9014, the greater the thrust output by the hydraulic transmission, and the greater the clamping force of the slant block 9021 and the clamping cap 11 on the tapered collet 10 and the milling cutter. The stability of the milling cutter's rotation is also higher. The device can adaptively adjust the clamping force according to the temperature change of the milling cutter itself. The higher the temperature, the tighter the clamping, avoiding loosening and slippage of the milling cutter during high-speed machining, and ensuring machining safety and accuracy.

[0039] When the processing stops and the temperature drops, the shape memory alloy spring 9014 returns to its original length, and the return spring 9011 pushes the elastic piston 9010 upward to reset, causing the guide rod 9012, ring seat 9013, extension rod 9016, and first hydraulic piston 9015 to return to their positions in sequence. Hydraulic oil flows back from hydraulic cylinder 9017 to hydraulic chamber 909, and the second hydraulic piston 9019, pressure rod 9020, and slant block 9021 retract synchronously, restoring the clamping force to the initial clamping state. The first sealing ring 9024 in the sealing groove 9023 forms a seal at the insertion position of the extension rod 9016, and the second seal... The rubber ring 9025 moves synchronously with the first hydraulic piston 9015 to ensure the sealing effect of the upper part of the hydraulic chamber 909. The third sealing rubber ring 9026 moves synchronously with the second hydraulic piston 9019 to ensure the sealing effect inside the hydraulic cylinder 9017. The three sealing structures work together to prevent hydraulic oil leakage and ensure the stability of hydraulic transmission. The limiting post 9027 limits the maximum stroke of the second hydraulic piston 9019 to prevent the second hydraulic piston 9019 from dislodging from the hydraulic cylinder 9017. The end face of the curved block 9021 has an anti-slip groove 9028 to increase the friction with the contact surface of the cone clamping cylinder 10 and improve the clamping stability.
