Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a cooling device for cutting automotive parts. Background Technology

[0002] Cutting processes are mainly divided into rotary machining (turning, drilling, boring, milling), linear motion machining (planing, slotting), and abrasive machining (grinding). Currently, milling is commonly used in the machining of automotive parts to process complex shapes such as planes, grooves, and curved surfaces. During milling, it is often necessary to cool the cutting tool to prevent thermal deformation of the tool and workpiece due to high temperatures, thereby ensuring the machining accuracy of automotive parts and extending tool life.

[0003] Currently, the cooling operation for milling automotive parts often involves installing a spray pipe on the side of the cutting head to spray high-pressure coolant to cool the cutting head. However, since the spray pipe is fixed in place by a bracket, the coolant can only be sprayed from a fixed position. This results in the coolant spray at the fixed position failing to cover the entire cutting head, especially in areas far from the spray point where heat dissipation is insufficient, easily leading to localized high temperatures. This accelerates tool wear and affects the surface quality of the milled parts.

[0004] Therefore, we propose a cooling device for machining automotive parts. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling device for cutting automotive parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cooling device for cutting automotive parts includes: a circular ring plate disposed on the side of a cutting head; multiple connectors mounted on the circular ring plate for fixing to the main body of the cutting head; multiple support plates mounted on the bottom wall of the circular ring plate, the support plates being distributed in a circular array, each support plate having a mounting bracket rotatably connected to its side wall via a rotating seat, the mounting bracket having a cooling nozzle mounted thereon; and a power mechanism on the circular ring plate for spraying cooling liquid onto different positions on the side of the cutting head using the cooling nozzles.

[0008] Preferably, the power mechanism includes a plurality of sliding rods that are slidably connected to the top wall of the annular plate, the mounting bracket has rectangular holes symmetrically opened on its side wall, and limit rods are symmetrically fixedly connected to the side wall of the sliding rods.

[0009] Preferably, the power mechanism further includes a mating plate fixedly connected to the side wall of the slide rod, a ball guide rod fixedly connected to the bottom of the mating plate, and an annular guide block slidably connected to the top wall of the annular plate.

[0010] Preferably, the limiting rod and the adjacent rectangular hole slide through each other, and a return spring is fixedly connected to the side wall of the sliding rod, and the return spring is fixedly connected to the bottom wall of the annular plate.

[0011] Preferably, the top wall of the annular plate has an annular groove, the inner wall of the annular groove is fitted with an annular electric guide rail, an electric slider is slidably fitted on the annular electric guide rail, and the electric slider and the annular guide block are fixedly connected.

[0012] Preferably, the ball guide rod and the upper surface of the annular guide block slide against each other, and the top wall of the annular guide block is evenly provided with multiple continuous arc-shaped protrusions.

[0013] This utility model has the following beneficial effects:

[0014] 1. The installed annular plate is located diagonally above the side of the cutting head. By evenly distributing multiple cooling nozzles on the side of the cutting head, the coverage of the coolant sprayed by the cooling nozzles on the circumference of the side of the cutting head is improved, thereby enhancing the cooling effect on the cutting head.

[0015] 2. By setting up structures such as electric sliders, annular guide blocks, and sliding rods, the electric slider is turned on, and the sliding rod drives the mounting frame to rotate alternately in both directions around the rotating seat within a certain angle range through the limit rod and rectangular hole. Then the mounting frame will drive the cooling nozzle to rotate alternately in both directions synchronously, so that the coolant sprayed by the cooling nozzle can be sprayed at different positions along the axis of the cutting head, further improving the cooling effect on the cutting head.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A cooling device for cutting automotive parts, comprising:

[0024] A circular ring plate 1 is disposed on the side of the cutting head; multiple connectors 15 are mounted on the circular ring plate 1, and the connectors 15 are used to fix the cutting head body; multiple support plates 6 (such as...) are mounted on the bottom wall of the circular ring plate 1. Figure 1 As shown, multiple support plates 6 are distributed along a circular array. Each support plate 6 has a rotating seat 2 fixedly installed on its side wall. The rotating part of the rotating seat 2 is fixedly connected to a mounting frame 8. A cooling nozzle 9 is installed on the mounting frame 8. The cooling nozzle 9 is connected to an external connecting pipe and is provided with high-pressure coolant sprayed out through a coolant drive system. The annular plate 1 is provided with a power mechanism that enables the cooling nozzle 9 to spray coolant at different positions along the axial direction on the side of the cutting tool head.

[0025] The power mechanism includes multiple sliding rods 3 that are slidably connected to the top wall of the annular plate 1. The sliding rods 3 slide vertically along the inner wall of the top wall of the annular plate 1. Rectangular holes 16 are symmetrically opened on the side wall of the mounting bracket 8 (in conjunction with...). Figure 1 and Figure 2 As shown), the slide bar 3 is symmetrically and fixedly connected to the limit rod 10 on its side wall.

[0026] The power mechanism also includes a mating plate 11 fixedly connected to the side wall of the slide bar 3. A ball guide rod 12 is fixedly connected to the bottom of the mating plate 11. A ball is embedded at one end of the ball guide rod 12 and freely rolling balls are embedded therein. An annular guide block 4 is slidably connected to the top wall of the annular plate 1.

[0027] The limiting rod 10 and the adjacent rectangular hole 16 slide through each other. A return spring 13 is fixedly connected to the side wall of the slide rod 3. The return spring 13 is fixedly connected to the bottom wall of the annular plate 1. The ball guide rod 12 and the upper surface of the annular guide block 4 slide against each other. The top wall of the annular guide block 4 is evenly provided with multiple continuous arc-shaped protrusions. Under the action of the return spring 13, the ball part of the ball guide rod 12 always slides against the top wall of the annular guide block 4.

[0028] The top wall of the annular plate 1 has an annular groove 5 (combined with...) Figure 3 and Figure 4 As shown), an annular electric guide rail 7 is installed on the inner wall of the annular groove 5, and an electric slider 14 is slidably fitted on the annular electric guide rail 7. (The annular electric guide rail 7 and the electric slider 14 are both existing technologies, and can be referred to the patent document CN113232113B. They will not be described in detail here.) The electric slider 14 and the annular guide block 4 are fixedly connected.

[0029] In this invention, the device is installed on the main body of the cutting head via the connector 15. At this time, the annular plate 1 is located at the side and slightly above the cutting head. The cooling nozzle 9 is supplied with high-pressure coolant by an external connecting pipe and coolant drive system, so that the high-pressure coolant is sprayed onto the side of the cutting head. By evenly distributing multiple cooling nozzles 9 on the side of the cutting head, the device can improve the coverage of the coolant sprayed by the cooling nozzles 9 on the circumferential side of the cutting head, thereby improving the cooling effect on the cutting head.

[0030] When it is necessary to improve the cooling effect at different positions on the side of the cutting head, the electric slider 14 is activated. The electric slider 14 will slide on the annular electric guide rail 7, which will drive the annular guide block 4 to slide on the circular plate 1 to produce a rotational effect. Under the action of the return spring 13, the ball part of the ball guide rod 12 always slides against the annular guide block 4. The top wall of the annular guide block 4 is evenly distributed with multiple continuous arc-shaped protrusions. During the process of the annular guide block 4 sliding along the circular trajectory, the annular guide block 4 will cause multiple ball guide rods 12 to move back and forth in the vertical direction. 12 will drive the corresponding slide bar 3 to reciprocate synchronously in the vertical direction through the mating plate 11. Since the slide bar 3 is symmetrically fixed with the limit rod 10 on the side wall, and the mounting frame 8 is symmetrically provided with rectangular holes 16 on the side wall, the limit rod 10 and the rectangular hole 16 slide through each other. Then the slide bar 3 will drive the mounting frame 8 to rotate alternately in the forward and reverse directions around the rotating seat 2 as the center within a certain angle range through the limit rod 10 and the rectangular hole 16. Then the mounting frame 8 will drive the cooling nozzle 9 to rotate alternately in the forward and reverse directions synchronously, so that the coolant sprayed by the cooling nozzle 9 can be sprayed at different positions in the axial direction of the cutting head, further improving the cooling effect on the cutting head.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
