Description

Technical Field

[0001] This utility model relates to the field of CNC tool holder manufacturing technology, and more specifically, to a CNC tool holder heat treatment processing device. Background Technology

[0002] CNC tool holders are core components connecting the spindle of a machining center to the cutting tool. During production, CNC tool holders often require heat treatment. For example, application number "202323590753.6" proposes a tool holder heat treatment cooling device, which includes a cooling box, a cooling reflux assembly, and a storage assembly. The cooling box has a rotating door on its front wall, with a controller and handle on the front wall of the rotating door. Casters are installed on the lower wall of the cooling box. The cooling reflux assembly is installed on the outer wall of the cooling box, and the storage assembly is installed on the inner wall of the cooling box. A water inlet pipe is installed on the upper wall of the water tank in the cooling reflux assembly. A first telescopic column is installed on the upper wall of the storage frame in the storage assembly. However, in the above technical solutions, the cooling reflux component only relies on the water pump to drive the cooling water to circulate between the cooling tank and the water tank. It lacks a structure design that actively enhances heat exchange. After the cooling water continuously absorbs the heat of the tool holder, it is difficult to cool down quickly through natural heat dissipation. This can easily lead to a gradual increase in the temperature of the circulating water. After long-term use, the cooling efficiency will decrease significantly, which cannot meet the high precision requirements of CNC tool holders for cooling rate stability. Therefore, we propose a CNC tool holder heat treatment processing device to solve the above problems. Utility Model Content

[0003] The main purpose of this utility model is to provide a CNC tool holder heat treatment processing device, which solves the problem that its cooling return component relies solely on a water pump to drive the cooling water to circulate between the cooling tank and the water tank. It lacks a structural design that actively enhances heat exchange. After the cooling water continuously absorbs the heat from the tool holder, it is difficult to cool down quickly through natural heat dissipation. This easily leads to a gradual increase in the temperature of the circulating water, and a significant decrease in cooling efficiency after long-term use. This fails to meet the high precision requirements of CNC tool holders for cooling rate stability.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A CNC tool holder heat treatment processing device includes a housing. Several nozzles are located at the upper end of the housing. A second placement frame is placed inside the housing. A cooling mechanism is installed on one side of the housing. The cooling mechanism includes a first placement frame, which is mounted on one side of the housing. A placement block is installed on the side of the first placement frame away from the housing. A groove is provided on the side of the placement block away from the housing. A flexible hose is installed inside the groove. A turntable is movably installed inside the groove. Several fixed rods are installed on the side of the turntable away from the housing. Rollers are movably installed on the outer sides of the fixed rods, and the rollers are in contact with the flexible hose. A motor is installed on the side of the first placement frame near the housing, and the output end of the motor is connected to the turntable. A first heat exchange tube and a second heat exchange tube are installed at the upper and lower ends of the first placement frame, respectively. The ends of the first and second heat exchange tubes that are close to each other are connected to the flexible hose, and the ends that are far apart from each other are connected to the nozzles and the housing, respectively.

[0005] Preferably, a door is installed at the front end of the box, and support frames are installed on both sides of the lower end of the box, with the second placement rack placed on the upper end of the support frames.

[0006] Preferably, a support block is installed at the upper end of the inner part of the box, a temporary storage box is installed at the lower end of the support block, the nozzle is installed through the lower end of the inner part of the temporary storage box, a water storage tank is installed on the upper surface of the box, and a drainage groove is provided through the inner part of the support block of the water storage tank.

[0007] Preferably, the upper and lower ends of the drainage trough are connected to the water storage tank and the temporary storage tank, and valves are installed inside the drainage trough.

[0008] Preferably, the lower interior of the housing is inclined, a filter is installed on the lower surface of the housing, and a drain hole is provided through the lower interior of the housing, which is connected to the filter.

[0009] Preferably, the upper end of the first heat exchange tube is connected to the water storage tank, the lower end of the second heat exchange tube is connected to the filter, and flanges are respectively installed at the ends of the first and second heat exchange tubes that are close to each other and at both ends of the hose. The flanges that are close to each other are connected by screws.

[0010] Preferably, the groove has a movable slot inside, the turntable is movably installed inside the movable slot, several fixed blocks are installed between the first placement frame and the box, the motor is installed inside the fixed blocks, and the output end of the motor is movably installed through the movable slot and connected to the turntable.

[0011] Preferably, a transmission rod is installed on the side of the turntable away from the motor, and fan blades are installed on the transmission rod. Several exhaust grooves are provided through the interior of the first placement frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) In this utility model, an active heat exchange circulation system is constructed through a cooling mechanism. When the motor drives the turntable to rotate, the fixed rod drives the roller to squeeze the hose, forming a stable liquid transport force, so that the cooling liquid circulates efficiently between the second heat exchange tube, the hose, and the first heat exchange tube. At the same time, the turntable drives the fan blade to rotate through the transmission rod, and forms a directional airflow in combination with the exhaust groove of the first placement frame, continuously cooling the first heat exchange tube and the second heat exchange tube, actively reducing the temperature of the circulating liquid. Thus, even if multiple batches of CNC tool holders are processed continuously, the temperature of the circulating liquid can be kept stable, ensuring that the cooling rate always meets the cooling accuracy requirements of the CNC tool holder, and avoiding the impact of the heat treatment quality of the tool holder due to the decrease in cooling efficiency.

[0013] (2) In this utility model, the lower end of the box is set to be inclined. With the help of the drain hole, the cooling liquid containing impurities can be quickly guided to the filter to avoid the impurities from settling in the box. Then the filter performs deep filtration of the liquid and then drives the liquid circulation through the cooling mechanism. This effectively prevents impurities such as metal chips and oxide scale from entering the hose, heat exchange tube or nozzle, reducing the probability of pipe blockage and equipment failure. At the same time, it avoids impurities from adhering to the surface of the tool holder and affecting the cooling uniformity, ensuring the surface quality and performance stability of the CNC tool holder after heat treatment.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0017] like Figures 1 to 7 As shown in the figure, this utility model embodiment proposes a CNC tool holder heat treatment processing device, including a housing 1.

The ends of the first heat exchange tube 413 and the second heat exchange tube 414 that are close to each other are connected to the hose 406. The ends of the first heat exchange tube 413 and the second heat exchange tube 414 that are far apart from each other are connected to the nozzle 12 and the box 1, respectively.

[0018] like Figures 4 to 7As shown, in another embodiment of this utility model, a door 3 is installed at the front end of the box body 1, support frames 8 are respectively installed on both sides of the lower end of the box body 1, and a second placement rack 7 is placed on the upper end of the support frame 8. A support block 10 is installed at the upper end of the inside of the box body 1, and a temporary storage box 9 is installed at the lower end of the support block 10. A nozzle 12 is installed through the lower end of the inside of the temporary storage box 9. A water storage tank 2 is installed on the upper surface of the box body 1. A drain trough 11 is provided through the inside of the support block 10 of the water storage tank 2. The upper and lower ends of the drain trough 11 are connected to the water storage tank 2 and the temporary storage box 9. A valve is installed inside the drain trough 11. The lower end of the inside of the box body 1 is inclined. A filter 5 is installed on the lower surface of the box body 1. A drain hole 6 is provided through the lower end of the inside of the box body 1. The drain hole 6 is connected to the filter 5. The upper end of the first heat exchange tube 413 is connected to the water storage tank 2. The two heat exchange tubes are connected in a continuous manner. The lower end of the second heat exchange tube 414 is connected to the filter 5. Flanges 415 are installed at the ends of the first heat exchange tube 413 and the second heat exchange tube 414 that are close to each other and at both ends of the hose 406. The flanges 415 that are close to each other are connected by screws. The groove 405 has a movable groove 408 inside. The turntable 407 is movably installed inside the movable groove 408. Several fixing blocks 402 are installed between the first placement frame 401 and the box 1. The motor 403 is installed inside the fixing block 402. The output end of the motor 403 is movably installed through the movable groove 408 and connected to the turntable 407. A transmission rod 411 is installed on the side of the turntable 407 away from the motor 403. Fan blades 412 are installed on the transmission rod 411. Several exhaust grooves 416 are provided through the interior of the first placement frame 401.

[0019] Open the front door 3 of the housing 1, place the CNC tool holder to be heat-treated on the second placement rack 7, and then place the second placement rack 7 carrying the tool holder inside the housing 1, so that it is placed stably on the support racks 8 on both sides of the lower end inside the housing 1. Close the door 3 to complete the workpiece placement preparation. Then open the valve in the drain channel 11 that runs through the water storage tank 2 and the support block 10, so that the cooling liquid in the water storage tank 2 flows into the temporary storage tank 9 installed at the lower end of the support block 10 through the drain channel 11. The temporary storage tank 9 temporarily stores and buffers the cooling liquid, and then the cooling liquid flows through... Several nozzles 12, installed through the lower end of the temporary storage box 9, evenly spray the surface of the CNC tool holder on the second placement rack 7, initially cooling the tool holder. The sprayed coolant absorbs heat from the tool holder and falls into the inclined lower end of the box 1. Guided by the inclined surface, it flows through the drain hole 6 at the lower end of the box 1 into the filter 5 installed on the lower surface of the box 1. The filter 5 filters out impurities such as metal shavings and oxide scale from the coolant, obtaining clean coolant. Then, the first placement rack 401 is activated near the side of the box 1... A motor 403 installed inside the fixed block 402 drives a turntable 407 installed in the movable groove 408 inside the groove 405 to rotate. Several fixed rods 409 installed on the side of the turntable 407 away from the housing 1 rotate synchronously with the turntable 407. Rollers 410 movably installed on the outer side of the fixed rods 409 continuously squeeze the hose 406 installed inside the groove 405 due to rotation, forming a stable liquid conveying force. The clean cooling liquid in the filter 5 is drawn into the hose 406 through the second heat exchange tube 414 and then pushed to the first heat exchange tube 413. The transmission rod 411, which is installed on the side of the turntable 407 away from the motor 403, rotates synchronously with the turntable 407. The fan blade 412 installed on the transmission rod 411 rotates accordingly. Combined with the several exhaust slots 416 that are arranged through the inside of the first placement frame 401, a directional airflow is formed. The airflow continuously blows towards the first heat exchange tube 413 and the second heat exchange tube 414 installed at the upper and lower ends of the first placement frame 401, which cools the cooling liquid flowing in the tubes and reduces the liquid temperature. The cooled liquid flows into the water storage tank 2 through the upper end of the first heat exchange tube 413, completing the circulation of the cooling liquid. The water tank 2 can store enough coolant to meet the continuous cooling needs without frequent replenishment. The valve in the drain trough 11 can flexibly control the flow rate of coolant and adjust the liquid supply according to the cooling needs of the tool handle to avoid resource waste. The temporary storage tank 9 can buffer the coolant to prevent uneven spraying of the nozzle 12 due to unstable liquid flow rate. The design of multiple nozzles 12 can achieve full coverage of the coolant on the surface of the tool handle, avoid insufficient local cooling, and improve the cooling effect. The motor 403 drives the roller 410 to compress the hose 406 through the turntable 407 and the fixing rod 409 to form the conveying power. There is no need to set up an additional water pump, which simplifies the equipment structure and reduces the equipment cost and maintenance difficulty. The fixing block 402 stably fixes the motor 403 to ensure the stability of the motor 403 during operation and avoids the liquid conveying efficiency being affected by the shaking of the motor 403. The first heat exchange tube 413 and the second heat exchange tube 414 serve as channels for liquid circulation, ensuring that the cooling liquid can flow in an orderly and efficient manner inside the equipment and realize recycling. The transmission rod 411 drives the fan blade 412 to rotate, and combined with the directional airflow formed by the exhaust groove 416, it can actively cool the cooling liquid in the first heat exchange tube 413 and the second heat exchange tube 414.

[0020] The working principle of this CNC tool holder heat treatment processing device: In use, first open the front door 3 of the housing 1, place the CNC tool holder to be heat-treated on the second placement rack 7, then place the second placement rack 7 carrying the tool holder inside the housing 1, so that it is placed stably on the support racks 8 on both sides of the lower end inside the housing 1, close the door 3, and complete the workpiece placement preparation. Then open the valve in the drain channel 11 that runs through the water storage tank 2 and the support block 10, so that the cooling liquid in the water storage tank 2 flows into the temporary storage tank 9 installed at the lower end of the support block 10 through the drain channel 11. The temporary storage tank 9 temporarily stores and buffers the cooling liquid, and then cools it down. Liquid is evenly sprayed onto the surface of the CNC tool holder on the second placement rack 7 through several nozzles 12 installed through the lower end of the temporary storage tank 9, initially cooling the tool holder. After absorbing the heat from the tool holder, the sprayed cooling liquid falls into the inclined lower end of the tank 1. Guided by the inclined surface, it flows through the drain hole 6 installed through the lower end of the tank 1 into the filter 5 installed on the lower surface of the tank 1. The filter 5 filters out impurities such as metal shavings and oxide scale from the cooling liquid, resulting in clean cooling liquid. Then, the first placement rack 401 is activated and moved closer to the tank 1. A motor 403, installed inside a fixed block 402 on one side, drives a turntable 407 installed in a movable groove 408 inside a recess 405 to rotate. Several fixed rods 409 installed on the side of the turntable 407 away from the housing 1 rotate synchronously with the turntable 407. Rollers 410 movably installed on the outer side of the fixed rods 409 continuously squeeze the hose 406 installed inside the recess 405 due to rotation, forming a stable liquid transport force. The clean cooling liquid in the filter 5 is drawn into the hose 406 through the second heat exchange tube 414 and then pushed to the first heat exchange tube 413. Meanwhile, the transmission rod 411 installed on the side of the turntable 407 away from the motor 403 rotates synchronously with the turntable 407, and the fan blade 412 installed on the transmission rod 411 rotates accordingly. Combined with the several exhaust slots 416 that are arranged through the inside of the first placement frame 401, a directional airflow is formed. The airflow continuously blows towards the first heat exchange tube 413 and the second heat exchange tube 414 installed at the upper and lower ends of the first placement frame 401, and performs air cooling to dissipate heat on the cooling liquid flowing in the tubes, thereby reducing the liquid temperature. The cooled liquid that has been cooled flows into the water storage tank 2 through the upper end of the first heat exchange tube 413, completing the circulation of the cooling liquid.

[0021] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
