Detailed Implementation
[0018] This utility model provides a milling and turning device for machining the keyway on the end face of a camshaft.
[0019] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a base 1, a support frame 2 fixedly connected to one side of the top of the base 1, a keyway milling cutter body 3 mounted on the top of the support frame 2, a rotating seat 10 on one side of the support frame 2, a rotating structure, an adjustment structure one, and an adjustment structure two on the outer side of the rotating seat 10, two fixed seats 17 on one side of the rotating seat 10, and a hydraulic structure on the outer side of the fixed seats 17. The hydraulic structure includes a hydraulic cylinder three 15, which is fixedly connected to one side of the rotating seat 10. A connecting plate 16 is fixedly connected to the telescopic end of the hydraulic cylinder three 15, and one end of the connecting plate 16 is fixedly connected to the fixed seat 17. A through-shaft slot 11 and two protrusions two 14 are opened on one side of the rotating seat 10, and both protrusions two 14 are connected to the through-shaft slot 11. Both of the two protrusions 14 have protrusions 20 slidably disposed inside them. The two protrusions 20 are fixedly connected to the two fixed seats 17 respectively. The two fixed seats 17 have V-shaped clamping grooves 18 formed at opposite ends. The two V-shaped clamping grooves 18 are adapted to each other. The two fixed seats 17 have V-shaped clamping grooves 19 formed at opposite ends. The two fixed seats 17 are provided with clamping groove adapting clamps 21 at opposite ends. The V-shaped clamping grooves 19 are adapted to the clamping groove adapting clamps 21. A connecting member is provided between the clamping groove adapting clamps 21 and the rotating seat 10. The connecting member includes an L-shaped connecting frame 22. The L-shaped connecting frame 22 is fixedly connected to the outside of the clamping groove adapting clamps 21. One end of the L-shaped connecting frame 22 is fixedly connected to the rotating seat 10.
[0020] Specifically, the camshaft is placed between the clamping groove adapter 21 and the V-shaped clamping groove 19. The hydraulic cylinder 15 is activated, and its extension end drives the fixed seat 17 to move towards the clamping groove adapter 21 through the connecting plate 16. The second protrusion 20 on the fixed seat 17 slides inside the second protrusion 14, thereby improving the movement stability of the fixed seat 17. Through the movement of the fixed seat 17, the clamping groove adapter 21 is embedded inside the V-shaped clamping groove 19, thereby completing the fixation of the camshaft in the vertical state. At this time, the keyway end face of the camshaft can be machined by the keyway milling cutter equipment body 3.
[0021] When keyway machining is required on the camshaft surface, the camshaft is inserted into the through-shaft slot 11, so that the camshaft to be machined is below the keyway milling cutter body 3. The two hydraulic cylinders 15 are activated to move the two fixed seats 17 in opposite directions. The camshaft is horizontally fixed by the cooperation of the two V-shaped clamping slots 18, so that the keyway milling cutter body 3 can be used to machine the keyway on the camshaft surface.
[0022] Example 2, please refer to Figure 3The rotating structure includes a hollow support 7, which is rotatably connected to the outside of the rotating seat 10. The hollow support 7 is provided with a worm gear 12 and a worm 13 inside. The worm gear 12 is fixedly connected to the outside of the rotating seat 10, and the worm 13 is meshed with the bottom of the worm gear 12. Both ends of the worm 13 pass through the inside of the hollow support 7 and are rotatably connected to the hollow support 7. A forward and reverse motor is fixedly connected to the front side of the hollow support 7, and the output end of the forward and reverse motor is fixedly connected to the worm 13.
[0023] Specifically, starting the forward and reverse motors (the specific model is not limited, but depends on the compatible equipment) causes the output of the forward and reverse motors to drive the worm gear 13 to rotate. The worm gear 13 meshes with the worm wheel 12, and the worm wheel 12 drives the rotating seat 10 to rotate. Through this structural design, the horizontally fixed camshaft can be rotated so that the main body 3 of the keyway milling cutter can process its outer side. In addition, this rotating structure can also switch the two end faces of the vertically fixed camshaft, improving the practicality of the device.
[0024] Example 3, please refer to Figure 1 , Figure 2 and Figure 3 The first adjustment structure includes a mounting base 4, which is located at the bottom of the hollow bracket 7. The top of the mounting base 4 has a groove 400, and a protrusion 700 is slidably provided inside the groove 400. The protrusion 700 is fixedly connected to the bottom of the hollow bracket 7. The first adjustment structure also includes a fixing plate 8, which is fixedly connected to the rear side of the hollow bracket 7. Two hydraulic cylinders 9 are fixedly connected to one side of the fixing plate 8, and both hydraulic cylinders 9 are fixedly connected to the top of the mounting base 4.
[0025] The second adjustment structure includes two hydraulic cylinders 5 and two T-shaped slide rails 6. Both hydraulic cylinders 5 are fixedly connected to one side of the mounting base 4. One end of each hydraulic cylinder 5 passes through the support frame 2 and is fixedly connected to the support frame 2. Both T-shaped slide rails 6 are fixedly connected to the top of the base 1. The mounting base 4 is slidably positioned between the two T-shaped slide rails 6.
[0026] Specifically, the two hydraulic cylinders 9 are activated, and their extension ends drive the fixed plate 8 to move. The fixed plate 8 drives the protrusion 700 on the hollow bracket 7 to slide inside the groove 400, thereby realizing the position adjustment of the hollow bracket 7 and the rotating seat 10, and adjusting the vertically fixed camshaft to the position to be processed.
[0027] Two hydraulic cylinders 5 are activated, and their extension ends drive the mounting base 4 to move. The mounting base 4 slides on two T-shaped slide rails 6, thereby fine-tuning the horizontally fixed camshaft so that the main body 3 of the keyway milling cutter can process it.
[0028] It should be noted that the synchronous operation of the two hydraulic cylinders 9 and the two hydraulic cylinders 5 is achieved through mechanical control technology, which is existing technology and will not be described in detail here.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
