Description

Technical Field

[0001] This utility model relates to the field of milling lathe technology, and more specifically, to a cooling device for bushing turning. Background Technology

[0002] There are many places where bushings are needed. The manufacturing of bushings requires multiple processes. When producing bushings, the material can be cut into blanks first. Then, the blanks need to be turned externally to clean the waste and rust on the outer surface of the blanks. Then, the inner surface of the bushing can be turned. When turning the bushings, coolant needs to be used to cool the turned surfaces of the bushings.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The embodiments disclosed in this application are as follows: Figures 1-7 The cooling device shown includes a base 1, a turning equipment body 2 on the top of the base 1, a mounting seat 3 on the outside of the turning equipment body 2, a milling cutter holder 4 mounted inside the mounting seat 3, a cavity 5 on the inside of the base 1, a hose 6 fixedly connected to one side of the base 1, a water pump 19 on the outside of the hose 6, and a cooling mechanism on the outside of the base 1 and the turning equipment body 2. The cooling mechanism includes multiple positioning frames 20, an annular pipe 7 fixedly connected to the inside of the positioning frames 20, one side of the annular pipe 7 fixedly connected to one end of the hose 6, multiple hoses 8 fixedly connected to one side of the annular pipe 7, a water supply pipe 9 fixedly connected to one end of the hose 8, and an electric cylinder 11 hinged to the bottom of the water supply pipe 9. The bottom end of the electric cylinder 11 is connected to the milling cutter holder 4. The tool holder 4 is hinged on the outside, and the water supply pipe 9 is hinged to the outside of the support 12. One end of the support 12 is fixedly connected to the outside of the milling cutter holder 4. One end of the water supply pipe 9 has an outlet 10. Multiple water supply pipes 9 are arranged in a ring array on the outside of the ring pipe 7. A collection mechanism is set on the inside of the base 1. Multiple electric cylinders 11 are used to push the water supply pipe 9 and the outlet 10 to deflect, so that the outlet 10 can adjust the spray angle of the coolant, so that the coolant is delivered directly to the tool tip, effectively reducing the cutting temperature of the turning tool head and the bushing workpiece, allowing the coolant to have better contact with the surface of the tool head and the bushing workpiece, maintaining uniform cooling of the tool head and the bushing workpiece, and keeping the bushing workpiece at a stable temperature throughout the machining process, thereby greatly reducing thermal deformation and ensuring the machining dimensional accuracy.

[0020] Reference Figure 4 , Figure 5 and Figure 7As shown, the collection mechanism includes a filter plate 13, the outer side of which is fixedly connected to the inner side of the base 1. The filter plate 13 has a "V" shaped cross section. A baffle 14 is hinged to one side of the base 1. A handle 15 is fixedly connected to one side of the baffle 14. A retaining seat 16 is fixedly connected to one side of the baffle 14. A fixed shaft 17 is fixedly connected to the outer side of the base 1. A rotating rod 18 is rotatably connected to the outer side of the fixed shaft 17. One side of the rotating rod 18 is engaged with the inner side of the retaining seat 16. The "V" shaped filter plate 13 can collect chips and filter coolant simultaneously. The rotation of the rotating rod 18 can engage the retaining seat 16. The deflection of the baffle 14 can clean the chips on the surface of the filter plate 13 inside the base 1.

[0021] The working principle of this utility model is as follows: During the turning process of the bushing, the bushing workpiece is first placed in the main body 2 of the turning equipment. The bushing workpiece is clamped by a three-jaw chuck, and the main body 2 of the turning equipment is started, which drives the bushing workpiece to rotate through the three-jaw chuck. Then, the operator operates the mounting base 3 to drive the milling cutter 4 to turn the rotating bushing workpiece. When the turning head at one end of the milling cutter 4 is inserted into the bushing workpiece, some coolant is injected into the cavity 5 in advance. The water pump 19 is started to draw the coolant from the cavity 5 into the annular pipe 7 through the hose 6. Then, the four electric cylinders 11 push one end of the water supply pipe 9 to deflect around the support 12. The outlet 10 on one side of the water pipe 9 allows adjustment of the coolant spray angle, enabling better contact between the coolant and the machined area of ​​the bushing workpiece. This achieves a better cooling effect on the surface of the machining tool and the bushing workpiece. Simultaneously, the machined bushing workpiece residue and coolant fall into the base 1. The residue is filtered by the filter plate 13, allowing the coolant to pass through the filter plate 13 and re-accumulate inside the cavity 5 for circulation via the hose 6. Then, rotating the lever 18 moves one end out from the inside of the retainer 16, opening the baffle 14 from one side of the base 1. This allows for cleaning of the residue filtered by the filter plate 13. (See attached diagram.) Figure 7 As shown, attached Figure 7 It can be seen that the deflected lever 18 is engaged with the card holder 16, and finally completes the opening and closing of the baffle 14.
