Description

Technical Field

[0001] This utility model belongs to the technical field of gear hobbing equipment, specifically relating to a cutting fluid delivery mechanism for a gear hobbing machine. Background Technology

[0002] As automotive components, bushings require tooth profile machining on their end faces. During the machining process using a gear hobbing machine, the cutting tools need to be cooled and lubricated to ensure tool life and optimal machining results.

[0003] Traditionally, adding cutting fluid is mostly done manually. Existing cutting fluid delivery mechanisms are generally large, independent systems that continuously deliver water-like cutting fluid during the gear hobbing process, resulting in high gear hobbing costs. Although cutting fluid delivery mechanisms are often accompanied by cutting fluid circulation and collection systems to reduce processing costs, these systems also increase processing costs.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 In this embodiment, the gear hobbing machine includes a movable base and a tool holder 6 mounted on the movable base. The tool holder 6 includes a connecting part 61 and a mounting part 62, with the connecting part 61 and the mounting part 62 forming an included angle of 130°. The cutting fluid delivery mechanism mounted on the gear hobbing machine includes a dripping pot 1, a delivery pipe 2, and a bracket 3. The dripping pot 1 is suspended on a column. The input end of the delivery pipe 2 is connected to the output end of the dripping pot. A flow controller 4 is provided on the delivery pipe 2 to control the flow rate of the cutting fluid, so that the cutting fluid cools the tool in the form of dripping liquid. The bracket 3 is connected to the mounting part 62, and the top of the bracket 3 is provided with a mounting hole that matches the output end of the delivery pipe 2 for mounting the output end of the delivery pipe 2.

[0025] In this invention, the cutting fluid is delivered to the cutting tool by dripping, which ensures the cooling effect of the tool and reduces processing costs.

[0026] Reference Figures 2-4 In one embodiment, the bracket 3 includes a vertical plate 32 and a flat plate, the flat plate being perpendicular to the vertical plate 32. The flat plate includes a first flat plate 331 and a second flat plate 332, the first flat plate 331 and the second flat plate 332 being partially overlapped. The second flat plate 332 is connected to the vertical plate 32 through the first flat plate 331. An angle adjustment component is provided between the first flat plate 331 and the second flat plate 332 to achieve precise delivery of cutting fluid under different knurling requirements. Specifically, refer to... Figure 5The angle adjustment assembly includes a housing 341, a worm gear 342 and a worm 343 rotatably mounted in the housing 341 via bearings, and a wheel axle 344 connected to the worm gear 342 shaft. A housing 341 mounting groove is provided on the top of the first plate 331 to fit the housing 341, and the housing 341 is embedded in the first plate 331 through the housing 341 mounting groove. One end of the worm 343 passes through the housing 341 and extends to the outside of the first plate 331. The first plate 331 has a rod groove to fit the worm 343 outside the housing 341. A first knob 345 is fixedly provided at the end of the extension of the worm 343. The top of the wheel axle 344 passes through the housing 341 and is fixedly connected to the bottom of the first plate 331. By manually rotating the knob, the worm 343 is driven to rotate, and the worm gear 342 rotates under the drive of the worm 343, realizing the synchronous rotation of the wheel axle 344, thereby adjusting the angle of the second plate 332. Multiple through holes can be provided on the second plate to cooperate with the conveying pipe, and they can be arranged in an array along the vertical plate direction to assist the angle adjustment component in adjusting its position.

[0027] In this invention, since the cutting fluid flows down in the form of droplets, the cross-sectional area of ​​the droplets is smaller than that of the water flow. By setting an angle adjustment component, the position can be adjusted for different specifications of tools. For example, if the tapered knurling wheel on the tool holder is replaced with a cylindrical knurling wheel, the cutting fluid can be dripped onto the tool by using the angle adjustment component.

[0028] The drip pot 1 is equipped with a liquid level sensor, which can be connected to the controller in the gear hobbing machine. The controller determines whether to sound an alarm based on the liquid level information to prevent the cutting fluid from running out.

[0029] Furthermore, referring to Figure 3 A sliding groove, T-shaped, is formed on the side of the vertical plate 32 near the first plate 331, preventing relative sliding between the vertical plate 32 and the first plate 331 on the horizontal plane. A slider 5 is provided on the side of the first plate 331 corresponding to the sliding groove. The slider 5 moves within the sliding groove to achieve the raising and lowering of the plate. (Refer to...) Figure 4 The mounting part 62 has a screw 71 fixedly mounted on its top. A threaded sleeve 72 is fitted over the screw 71. A mounting hole is provided on the first plate 331 to accommodate the sleeve 72. The sleeve 72 passes through the mounting hole and penetrates the first plate 331. A limiting ring 73 is fixedly fitted around the sleeve 72 at the bottom of the first plate 331 to support the first plate 331. The sleeve 72 can move up and down while rotating, thereby driving the first plate 331 to rise and fall, preventing the bracket 3 from affecting the knurling of workpieces of different specifications. Furthermore, a second knob 74 is provided on the top of the sleeve 72 for easy manual rotation of the sleeve 72.

[0030] Furthermore, referring to Figure 1 The tool holder 6 is equipped with a latch 8, the structure of which is as follows: Figure 6As shown, the conveying pipe 2 can be fixed to the knife bar 6 by the buckle 8. Of course, the buckle 8 can also be set on the first plate 331 or simultaneously. The number of buckles 8 can be set according to the actual situation. By setting the buckle 8, the movement of the conveying pipe 2 is restricted, preventing the conveying pipe 2 from sliding off the second plate 332 during the movement of the moving seat.
