Description

Technical Field

[0001] The utility model relates to the technical field of automotive optical components, in particular to a five-axis processing device for refractive tooth patterns on the surface of a light guide lens. Background Technique

[0002] Vehicle lamps are tools for road lighting when vehicles are driving at night and also tools for emitting various vehicle driving signals. Vehicle lamps are generally divided into headlamps and combined taillights. Automotive vehicle lamps are an important part of a vehicle. They not only provide necessary lighting for the driver to ensure that the road ahead can be clearly seen at night or in low-light conditions, thereby improving driving safety. In addition, vehicle lamps also have the function of safety warning, and different light signals are used to prompt other road users. For example, the brake lamp is used to prompt the vehicle behind to decelerate or stop, and the turn signal is used to indicate the driving direction of the vehicle.

[0003] When vehicle lamps are produced, an array of refractive tooth patterns needs to be processed on the surface of the light guide lens of the vehicle lamp to meet the requirement of emitting a beam with specific requirements. Most of the existing refractive tooth patterns on the surface of light guide lenses are processed by five-axis equipment. The light guide lens is fixed in a centering clamp, the main shaft motor rotates to drive the cutting tool to rotate at high speed, and through the mutual cooperation of the three-axis module and the rotary table, refractive tooth patterns are processed on the surface of the light guide lens. When the traditional five-axis processing device for refractive tooth patterns on the surface of a light guide lens works, the centering clamp fixes the light guide lens and only fixes it through two contact points, and the fixing effect is poor. When processing the refractive tooth patterns, the light guide lens will displace in the direction where it is not fixed, affecting the processing accuracy of the refractive tooth patterns.

The stable clamping mechanism 4 further includes a knob 47. The knobs 47 are all arranged at the outer ends of the first lead screws 45, providing drive for the adjustment of the clamping blocks 46.

[0023] Among them, the stable clamping mechanism 4 further includes a driving component 48. The driving component 48 includes a second lead screw 481, a worm gear 482, a worm 483 and a driving motor 484.

Fixed through four contact points, displacement of the optical guide lens is avoided, and the processing accuracy of the refractive tooth pattern is improved.

[0025] The working principle of the present utility model is as follows:

[0026] When processing the refractive tooth pattern, first adjust the position of the clamping block 46 according to the size of the optical guide lens. Rotate the knob 47, and the first lead screw 45 also rotates accordingly. Since the outer surface of the first lead screw 45 is threadedly connected to the middle inside of the vertically adjacent clamping block 46, as the first lead screw 45 rotates, the four clamping blocks 46 move synchronously. When the clamping block 46 reaches the appropriate position, place the optical guide lens above the supporting block 9. The single-chip microcomputer 8 controls the driving motor 484 to operate. The output shaft of the driving motor 484 drives the worm 483 to rotate. Since the worm gear 482 is meshed with the worm 483, as the worm 483 rotates, the worm gear 482 also rotates accordingly, driving the second lead screw 481 to rotate synchronously. Since the outer surface of the second lead screw 481 is threadedly connected to the middle inside of the limit frame 44, as the second lead screw 481 rotates, the limit frame 44 also moves upward, driving the limit post 43 to move upward synchronously. The limit post 43 continuously presses the limit groove 42, causing the four limit grooves 42 to move inward synchronously, driving the four moving blocks 41 to move inward synchronously until the four clamping blocks 46 all contact the surface of the optical guide lens. At this time, the optical guide lens is fixed. The single-chip microcomputer 8 controls the main shaft motor 6 to operate. The output shaft of the main shaft motor 6 drives the cutting tool 7 to rotate at high speed. At the same time, the single-chip microcomputer 8 controls the three-axis module 5 and the rotary worktable 2 to work. The three-axis module 5 drives the main shaft motor 6 and the cutting tool 7 to move along the X, Y, and Z axes. The rotary worktable 2 drives the optical guide lens to rotate and deflect. The three-axis module 5 and the rotary worktable 2 cooperate with each other to quickly process the refractive tooth pattern on the surface of the optical guide lens.

[0027] It should be noted that in the above embodiments, the single-chip microcomputer 8 disclosed is the S7-200 single-chip microcomputer, the rotary worktable 2 is the KFR-320 rotary worktable, the driving motor 484 is the LS28A18 motor, the three-axis module 5 is the FSL120XYZ-L three-axis module, and the main shaft motor 6 is the FTD653B-18 / 2.2 motor.
