Description

Technical Field

[0001] This invention relates to the field of variable intake timing mechanism processing equipment, specifically a variable intake timing mechanism and its processing equipment. Background Technology

[0002] The basic structure of a variable valve timing mechanism mainly consists of a variable valve camshaft timing adjuster, a hydraulic control valve, a crankshaft position sensor, a camshaft position sensor, and an engine management system. The crankshaft position sensor transmits the engine speed signal to the engine management system, and the crankshaft position sensor also transmits the cylinder identification signal to the engine management system. The engine management system analyzes and calculates the signal, then issues commands, outputting current (duty cycle) to control the hydraulic control valve. This changes the high-pressure oil passage of the hydraulic control valve, which in turn controls the variable valve timing actuator to adjust the intake camshaft phase to achieve optimal valve timing. The camshaft is a component in a piston engine; its function is to control the opening and closing of the valves. Although the camshaft rotates at half the speed of the crankshaft in a four-stroke engine, it still rotates at a very high speed and needs to withstand a large torque. Therefore, the design of the camshaft requires high strength and support. Its material is generally special cast iron, and occasionally forgings are used. The machining of the camshaft mainly includes drilling the center hole, precision turning the journal, machining the hole and timing groove, precision turning the thrust surface, precision grinding the wheelbase, precision grinding the cam, polishing, assembly, and final measurement. In the precision grinding process, a grinding machine specially designed for precision grinding of camshafts is required. A grinding machine is a machine tool that uses abrasives to grind workpieces to obtain the required shape, size, and precision machined surface.

[0003] Existing grinding machines require the camshaft to be placed on a headstock and tailstock connected to the worktable during operation. An internal drive mechanism rotates the camshaft, and a grinding wheel holder is located on the side of the camshaft. The grinding wheel inside the holder grinds the hub side of the camshaft. Before grinding, the camshaft and the headstock / tailstock must be aligned using a detector to ensure the camshaft rotates around its axis, guaranteeing a fixed grinding distance. However, existing equipment cannot detect the camshaft's axis during operation, potentially causing slight misalignment that is difficult to detect visually, affecting product quality. Furthermore, existing equipment cannot detect the thickness of the grinding wheel during use; it can only be visually inspected after use, resulting in untimely inspection, reduced production precision, and lower product quality. Therefore, we propose a variable intake timing mechanism and its processing equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a variable intake timing mechanism and its processing equipment to solve the problems mentioned in the background art.

Simultaneously, the sensing components detect the grinding wheel's surface, providing rapid detection and early warning when grinding wheel wear is severe, preventing reduced camshaft machining performance and ensuring greater stability during grinding.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-8 The present invention provides a technical solution:

[0030] Example 1,

[0031] A variable intake timing mechanism processing device, comprising:

[0032] The main frame 1 is a cuboid structure, with its bottom end connected to the ground; the top end of the main frame 1 is equipped with a fixing component 2 for fixing the processed parts.

[0033] Grinding assembly 4 is provided at the top of the main frame 1 for grinding the side of the workpiece to meet the workpiece's usage standards;

[0034] The detection component 5 is located at the top of the main frame 1 and contacts one end of the processing part;

[0035] The sensing component 6 is located on the side of the grinding component 4, and one end of the sensing component 6 is in contact with the side of the grinding component 4.

[0036] The sensing component 6 includes a main body base 61, which is fixedly connected to the bottom of the main frame 1. A horizontal plate 62 is slidably connected to the inner wall of the main body base 61 via a horizontal shaft. A transmission gear 64 is provided at the bottom of the horizontal plate 62. A rotating wheel 63 is rotatably connected to the inner wall of the main body base 61. An alarm 65 is fixedly connected to the front of the main body base 61. A crossbeam 66 is fixedly connected to the side of the horizontal plate 62. A spring shaft 68 is slidably connected to one end of the crossbeam 66. A support cover 67 is fixedly connected to the bottom of the crossbeam 66. The top of the crossbeam 66 is fixedly connected to one end of a tension spring 69. The side of the crossbeam 66 is at the center of the side of the horizontal plate 62. When the grinding component 4 slides along the surface hub of the camshaft 3, it will slide back and forth. The roller 42 and the abrasive... The plate 43 moves back and forth together, and at the same time the rotating wheel 63 starts to rotate, ensuring that the horizontal plate 62 slides steadily inside the main body 61. Then, the side of the rotating wheel 63 drives the bottom of the crossbeam 66 and the spring shaft 68 to always contact the lowest point of the inner wall of the abrasive plate 43. Since the tension spring 69 is in the tension state in the original state, when the abrasive plate 43 is damaged after wear, one end of the tension spring 69 will no longer be supported by the side of the abrasive plate 43, so that the tension spring 69 can be in the retracted state. Thus, the relative position of the spring shaft 68 and the crossbeam 66 can be used to judge whether the abrasive plate 43 is worn. During the sliding of the spring shaft 68, the side of the support cover 67 and the side of the spring shaft 68 play a supporting and protective role.

[0037] The detection component 5 includes a base 51. The base 51 is fixedly connected to the bottom of the main frame 1. The top of the base 51 is slidably connected to a slide plate 52. The inside of the slide plate 52 is slidably connected to a fixing rod 53. The outer edge of the fixing rod 53 is provided with a return spring 54. The inside of the slide plate 52 is rotatably connected to a rotating shaft 55. The side of the rotating shaft 55 is fixedly connected to a first gear 56. One end of the rotating shaft 55 is fixedly connected to a pointer 57. The side of the slide plate 52 is fixedly connected to a scale 58. The surface of the scale 58 is provided with a disc 59. The side of the slide plate 52 is fixedly connected to a toothed bar 510.

[0038] A small gear 511 is rotatably connected to the side plate of the rack 510. A large gear 512 is rotatably connected to the side of the small gear 511. A slider 514 is rotatably connected to the side of the large gear 512. A limit shaft 513 is slidably connected inside the slider 514. A reference ruler 515 is fixedly connected to the side of the base 51. A second rotating shaft 516 is rotatably connected inside the slide plate 52. A second gear 517 is fixedly connected to the side of the second rotating shaft 516. A slide rail 518 is fixedly connected to the side of the second rotating shaft 516. The interior of the slide rail 518 is connected to the transmission rod. One end of the transmission rod 519 is slidably connected. Since the top of the transmission rod 519 has a ring located at one end of the camshaft 3, and limiting rings are provided on both sides of the ring to prevent changes in the relative position of the transmission rod 519 and the camshaft 3, before using the detection component 5, one end of the transmission rod 519 must first be fitted onto one end of the camshaft 3. During the rotation of the camshaft 3 as the fixing component 2 opens, if the position of one end of the camshaft 3 shifts, it will cause the transmission rod 519 to shift as well. Simultaneously, the bottom end of the transmission rod 519 has a cylindrical section that can... The slide rail 518 slides inside, allowing the transmission rod 519 to move and transmit the movement of the slide rail 518. During the rotation of the slide rail 518, the rotating shaft 516 and the second gear 517 rotate together, which in turn causes the first gear 56 and the pointer 57 to rotate together, thus causing the pointer 57 to be displayed on the surface of the disc 59. This reduces the vertical deflection angle of the slide rail 518 and the transmission rod 519, preventing shrinkage. If the transmission rod 519 moves laterally, it will cause the slide rail 518 and the slide plate 52 to move back and forth. The return spring 54 provides guidance, and the fixing rod 53 provides reset. The rack tooth 510 on the side of the slide plate 52 will cause the small gear 511 and the large gear 512 to deflect together, which will cause the slider 514 to slide horizontally along the two sets of limit shafts 513. The positional relationship between the side of the slider 514 and the reference ruler 515 can be used to determine the back and forth deflection angle of the transmission rod 519, and thus determine the deflection angle of the camshaft 3 during the processing, thereby realizing the detection of the position offset of the camshaft 3.

[0039] The fixing component 2 includes a tailstock 21, which is slidably connected to the top of the main frame 1. A fixing frame 22 is fixedly connected to the side of the tailstock 21. A headstock 23 is provided at the opposite position of the fixing frame 22. A stabilizing frame 24 is rotatably connected to the side of the headstock 23. A driving block 25 is rotatably connected to the side of the headstock 23. One end of the driving block 25 is engaged with one end of the connecting pin 26. The stabilizing frame 24 is divided into upper and lower ends and holds one end of the camshaft 3. At the same time, one end of the camshaft 3 is embedded in the drive block 25 and the connecting pin 26. When the connecting pin 26 rotates and heats one end of the drive block 25, the connecting pin 26 is in a tightened state and holds one end of the camshaft 3. The other end of the camshaft 3 is held by one end of the fixing frame 22, so that the camshaft 3 can be horizontally fixed. At the same time, the headstock 23 drives the drive block 25 and the camshaft 3 to rotate together, and the surface of the camshaft 3 is ground by the grinding component 4.

[0040] The grinding assembly 4 includes a drive component 41. The drive component 41 is fixedly connected to the top of the main frame 1. The output shaft of the drive component 41 is rotatably connected to a roller 42. The side of the roller 42 is fixedly connected to a grinding disc 43. The grinding assembly 4 can slide back and forth on the surface of the main frame 1, so that the side of the grinding disc 43 can perform grinding operations on the hub of the camshaft 3 during rotation, and meet the usage standards.

[0041] The side of the first gear 56 meshes with the side of the second gear 517. The diameter of the first gear 56 is three times the diameter of the second gear 517. The slider 514 is in the middle position of the reference ruler 515 in its original state. The first gear 56 can drive the second gear 517 to rotate. The different diameters can reduce the rotation angle of the pointer 57, making it easier for personnel to observe the deflection angle over a larger range.

[0043] Includes a camshaft 3, which is located inside the fixed assembly 2. The camshaft 3 has a hub and a cross shaft inside, and the surface of the hub of the camshaft 3 is rough before use.
