Description

Technical Field

[0001] This utility model relates to the field of CNC tool processing technology, and in particular to a heating and quenching device for CNC tools. Background Technology

[0002] In CNC tool machining, the tool needs to be quenched and then rapidly cooled with coolant. However, existing quenching devices have several problems: metal chips are generated on the tool surface during cooling. These chips deposit or suspend in the coolant, which can affect the coolant's performance and significantly reduce its lifespan; contamination of the coolant can also lead to a decrease in the surface quality of the tool, affecting its cutting performance; and once metal chips enter the coolant, cleaning them is very troublesome.

[0003] To address the aforementioned issues, CN217173812U discloses a heating and quenching device for CNC cutting tools. The solution involves a motor-driven threaded rod that moves the cutting tool horizontally between the quenching equipment and a water tank. A pneumatic telescopic rod lowers the tool into the water tank for cooling. A filter screen is installed inside the water tank to collect metal debris generated during cooling. However, this solution still has problems: ① The size of the tool placement slot is fixed, making it impossible to place tools of different specifications; ② It is best to replace the filter screen after each cooling cycle, but the filter screen is bolted to the water tank, making installation or removal inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heating and quenching device for CNC cutting tools, suitable for cutting tools of different specifications.

[0005] In order to achieve the purpose of this utility model, the following solution is proposed:

[0006] A heating and quenching device for CNC cutting tools includes a housing and a cooling box disposed inside the housing, two linear stroke mechanisms, two lifting rods, and two placement racks.

[0007] Two linear travel mechanisms are arranged side by side, each linear travel mechanism is connected to a lifting rod, which is used to move the lifting rod and the placement rack horizontally toward the cooling box;

[0008] The placement rack includes a horizontal plate and multiple support blocks. The middle section of the top of the support block is rotatably connected to the horizontal plate. The two ends of the top of the support block are respectively provided with grooves of different sizes. The bottom of the lifting rod is connected to the corresponding horizontal plate. The long axis of the horizontal plate is consistent with the direction of the linear stroke mechanism and perpendicular to the long axis of the support block. The positions of the support blocks at the bottom of the two horizontal plates correspond one-to-one. The two grooves of the corresponding support blocks are used to place the same tool.

[0009] Furthermore, it also includes a conveying platform, a pallet, and multiple connectors for automatically placing and removing the filter screen from the cooling box. The conveying platform is located on the outside of the box, and a first window is provided on the side wall of this side of the box. The cooling box is located below the first window. A slide rail is provided on the top of the conveying platform, and the slide rail connects to the pallet. The filter screen is placed at a preset position on the top of the pallet. The slide rail is used to allow the pallet to pass through the first window until the filter screen is located directly above the cooling box. Multiple connecting posts are symmetrically located on the outer periphery of the top of the filter screen, and multiple connectors are respectively located below the horizontal plate. When the placement rack moves to the top of the cooling box, the connectors move down to clamp the corresponding connecting posts.

[0010] Furthermore, a total of four connectors are provided, symmetrically arranged in pairs at the ends of the horizontal plate. Each connector includes two clamping plates, a spring, and an L-shaped support plate. The longitudinal section of the L-shaped support plate is connected to the horizontal plate. The clamping plate includes an adjustment part and a clamping part located at the bottom of the adjustment part. The adjustment part is inclined, and the included angle between the two is an obtuse angle. The adjustment parts of the two clamping plates are rotatably connected to both sides of the horizontal section of the L-shaped support plate. The two side walls of the horizontal section of the L-shaped support plate are provided with guide posts. The corresponding position of the adjustment part is provided with an arc-shaped guide groove. The guide posts match the guide grooves. The clamping part is L-shaped, and the two clamping parts are connected by a spring. The connecting post includes a first cylinder and a second cylinder located at the top of the first cylinder. The diameter of the second cylinder is larger than that of the first cylinder. When the connector moves down aligned with the connecting post, the second cylinder will open the two clamping parts.

[0011] Furthermore, a second window is provided on the side wall of the box where the first window is located. The second window and the placement rack are located on both sides of the cooling box. Four columns are provided on the top plate of the box, which are located above the second window. When the placement rack moves to the second window, the lifting rod is used to move the placement rack up until the column contacts and presses down the adjustment part of the corresponding connector, so that the connector loosens the connecting column.

[0012] Furthermore, an L-shaped limiting plate is provided at the diagonal position at the top of the tray to restrict the filter screen.

[0013] Furthermore, the bottom surface of the tray is flush with the top surface of the cooling box.

[0014] The beneficial effects of this utility model are as follows: the middle section of the top of the support block is rotatably connected to the horizontal plate, and the two ends of the top of the support block are respectively provided with grooves of different sizes. In this way, various different specifications of knives can be placed in the grooves of corresponding sizes. The operation is simple. The support block has two rotation positions. By rotating the support block, the required groove can be rotated to the inside of the horizontal plate. Attached Figure Description

[0022] like Figure 1 , Figure 3 , Figure 4 As shown, this embodiment provides a heating and quenching device for CNC cutting tools, including a housing 1 and a cooling box 2 disposed in the housing 1, two linear stroke mechanisms 3, two lifting rods 4, and two placement racks 5.

[0023] Specifically, two linear stroke mechanisms 3 are arranged side by side, and each linear stroke mechanism 3 is connected to a lifting rod 4, which is used to move the lifting rod 4 and the placement frame 5 horizontally in the direction of the cooling box 2. The lifting rod 4 is used to move the placement frame 5 vertically. There are many ways to implement the linear stroke mechanism 3, such as using a motor to drive the lead screw. There are also many ways to implement the lifting rod 4, such as using a cylinder, oil cylinder or hydraulic cylinder to drive it.

[0024] Specifically, such as Figures 2-4 As shown, each placement rack 5 includes a horizontal plate 51 and three support blocks 52. The middle section of the top of the support block 52 is rotatably connected to the horizontal plate 51. The two ends of the top of the support block 52 are respectively provided with grooves 53 of different sizes. The bottom of the lifting rod 4 is connected to the corresponding horizontal plate 51. The long axis of the horizontal plate 51 is in the same direction as the long axis of the linear stroke mechanism 3. The long axis of the horizontal plate 51 is perpendicular to the long axis of the support block 52. The positions of the support blocks 52 at the bottom of the two horizontal plates 51 correspond one-to-one. The two grooves 53 of the corresponding support blocks 52 are used to place the same tool.

[0025] The method of use is as follows: Select the required groove 53 size in advance according to the specifications and dimensions of the tool. The support block 52 has two rotation positions. By rotating the support block 52, the required groove 53 can be rotated to the inside of the horizontal plate 51.

[0026] When the cutting tool is cooled in the cooling tank 2, metal shavings will be generated on the surface of the cutting tool. These shavings will be deposited or suspended in the coolant. To solve this problem, a filter screen 61 needs to be installed in the cooling tank 2. To facilitate the installation or removal of the filter screen 61, the following measures are taken in this embodiment:

[0027] like Figures 1-3 , Figure 6 As shown, the device also includes a conveying platform 62, a pallet 63, and multiple connectors 64. The number of connectors 64 can be set according to actual conditions. In this embodiment, there are four connectors 64 for clamping the filter screen 61, automatically placing the filter screen 61 into the cooling box 2, and automatically removing the filter screen 61. The conveying platform 62 is located on the outside of the box body 1. The side wall of the box body 1 on this side has a first window 11. The cooling box 2 is located below the first window 11. The top of the conveying platform 62 has a slide rail, which connects to the pallet 63. The bottom surface of the pallet 63 is flush with the top surface of the cooling box 2. The filter screen 61 is placed at a preset position on the top of the tray 63. An L-shaped limiting plate 631 is provided at the diagonal position on the top of the tray 63. The L-shaped limiting plate 631 is used to limit the position of the filter screen 61. The slide rail is used to allow the tray 63 to pass through the first window 11 until the filter screen 61 is located directly above the cooling box 2. Four connecting posts 65 are provided symmetrically on the outer periphery of the top of the filter screen 61. Four connecting pieces 64 are respectively provided below the horizontal plate 51. When the placement frame 5 moves to the top of the cooling box 2 under the action of the linear travel mechanism 3, the connecting pieces 64 are used to clamp the corresponding connecting posts 65.

[0028] The specific implementation methods of connector 64 and connecting post 65 are as follows: Figures 3-5 , Figure 7 As shown, the connectors 64 are symmetrically arranged at the ends of the horizontal plate 51 in pairs. Each connector 64 includes two clamping plates 641, a spring 642, and an L-shaped support plate 643. The top of the longitudinal section of the L-shaped support plate 643 is connected to the horizontal plate 51. The clamping plate 641 includes an adjustment part and a clamping part located at the bottom of the adjustment part. The adjustment part is inclined, and the angle between the adjustment part and the clamping part is an obtuse angle. The adjustment parts of the two clamping plates 641 are X-shaped, and the adjustment parts of the two clamping plates 641 are... The L-shaped support plate 643 is connected to both sides of the horizontal section of the L-shaped support plate 643. The two side walls of the horizontal section of the L-shaped support plate 643 are provided with guide posts 644. The corresponding position of the adjustment part is provided with an arc-shaped guide groove 645. The guide posts 644 are matched with the guide groove 645. The clamping part is L-shaped. The two clamping parts are connected by a spring 642. The connecting post 65 includes a first cylinder 651 and a second cylinder 652 provided on the top of the first cylinder 651. The diameter of the second cylinder 652 is larger than that of the first cylinder 651.

[0029] The method of use is as follows: First, use the slide rail to pass the tray 63 through the first window 11 until the filter screen 61 is directly above the cooling box 2; then... Figure 2From the perspective, the cutting tool on the placement rack 5 completes the quenching step on the left side of the housing 1; using two linear stroke mechanisms 3, the two placement racks 5 are moved synchronously to directly above the filter screen 61, at which point the connecting piece 64 is directly above the corresponding connecting post 65; using two lifting rods 4, the two placement racks 5 are moved synchronously downward until the connecting piece 64 contacts the connecting post 65. The second cylinder 652 will first open the clamping parts of the two connecting pieces 64, and then pass over the horizontal section of the clamping parts. The two clamping parts clamp the connecting post 65 under the action of the spring 642. Then, the two lifting rods 4 are used to move the two... The two placement racks 5 are moved upwards synchronously for a certain distance until the filter screen 61 is released from the L-shaped limiting plate 631. First, the slide rail is used to remove the tray 63 from the first window 11, thereby exposing the cooling box 2. The two placement racks 5 are moved downwards synchronously using the two lifting rods 4 until the filter screen 61 is lowered into the cooling box 2 and the coolant in the cooling box 2 covers the tool. Metal debris generated during the cooling process is deposited on the filter screen 61. After the cooling step is completed, the two placement racks 5 are moved upwards synchronously using the two lifting rods 4, and the filter screen 61 is also removed.

[0030] After the cooling process is completed, the filter screen 61 is removed from the cooling box 2. At this time, the filter screen 61 is still connected to the placement rack 5. In this embodiment, the filter screen 61 is removed in the following manner:

[0031] like Figure 1 , Figure 2 , Figure 4 As shown, the side wall of the box 1 with the first window 11 is also provided with a second window 12. The second window 12 and the placement rack 5 are located on both sides of the cooling box 2. The top plate of the box 1 is provided with four columns 13, which are located above the second window 12.

[0032] The method for removing the filter screen 61 is as follows: Use two linear travel mechanisms 3 to move the two placement racks 5 synchronously to the second window 12. At this time, the connector 64 is located directly below the corresponding column 13. Use the lifting rod 4 to move the placement rack 5 upward until the column 13 contacts and presses down the adjustment part of the corresponding connector 64. This will cause the connector 64 to loosen the connecting column 65, and the filter screen 61 will fall down. Remove the filter screen 61 from the second window 12.
