Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing, in particular to an automatic production line for automobile brake calipers. Background Art

[0002] The automotive brake caliper automated production line is one of the key equipment in modern manufacturing. It is used for mass production and assembly of caliper components in automotive brake systems. Since the outer shell and bracket of the automotive brake caliper have slight size deviations or shape errors during the processing, these errors will cause unstable performance of the assembled caliper or even failure if they are not corrected during the assembly process. Therefore, correction technology has become a key link in ensuring assembly quality. Through correction, these errors can be eliminated or reduced, making the fit between the outer shell and the bracket tighter and more accurate.

[0003] During the operation of the existing automobile brake caliper automated production line, there are slight deviations in the screw hole position or errors in the sensor itself, which will lead to inaccurate alignment during the assembly process, thereby affecting the assembly quality and performance stability of the brake caliper. Relying on a single alignment sensor for correction is difficult to adapt to the production needs of all types of calipers. When calipers of different models or specifications need to be produced, the parameters or position of the alignment sensor may need to be adjusted.

The shell 71 is dispersedly distributed, and a connecting plate 710 is fixedly connected to the inside of the shell 71. The connecting plate 710 is in a cross shape. A sliding groove is provided on the surface of the connecting plate 710. There are four groups of sliding grooves, and the insides of the four groups of sliding grooves are correspondingly slidably connected with a slide plate 79. One end of the connecting plate 710 is rotatably connected to the driven disk 76 through an axis. There are four groups of arc plates 711 distributed at equal intervals. The four groups of arc plates 711 are in contact with the inner walls of the screw holes provided on the surface of the shell 5 and the bracket. A notch 72 is provided on the surface of the shell 71, and the notch 72 corresponds to the arc plate 711 one by one, so that the arc plate 711 is adjusted according to the size of the screw hole, which is convenient for adjusting the screw holes of the shell 5 or the bracket of different sizes.

[0034] A fitting structure 8 is provided on one side of the clamping plate of the clamp 3. The fitting structure 8 includes a groove formed on the surface of the clamping plate. An inner plate 81 is fixedly connected to the inside of the groove. A convex plate 82 is provided on one side of the inner plate 81. Two groups of convex plates 82 are symmetrically provided with respect to the inner plate 81. One end of each of the two groups of convex plates 82 is rotatably connected to a swing plate 83 through an axis. Both ends of one group of swing plates 83 are rotatably connected to a fixed plate 84 through an axis. The fixed plate 84 is composed of two circular plates. The two circular plates are symmetrically provided on both sides of the axis. One end of the fixed plate 84 is symmetrically provided to the inner plate 81. A pressure rod 86 is provided on the side, one end of the pressure rod 86 is connected to a spring 85, both ends of the spring 85 are respectively connected to the fixed plate 84 and the pressure plate 87, one end of the pressure rod 86 is provided with a pressure plate 87, the pressure plate 87 is in contact with both ends of the shell 5 or the bracket, one end of the other set of swing plates 83 is also rotatably connected to the fixed plate 84 through the axis, a pressure rod 86 is provided on one side of the fixed plate 84, the surface of the pressure rod 86 is sleeved with a spring 85, and one end of the pressure rod 86 is provided with a pressure plate 87, so that the shell 5 or the bracket is fixed more firmly.

[0035] Specifically, first, the cylinder 11 embedded on the top surface of the assembly table 1 is driven to start, and the cylinder 11 drives the receiving plate 10 at the output end to move upward to be flush with the clamp 3, and then the housing 5 and the bracket that have been inspected in the previous step on the production line are clamped and fed to the clamps of the clamp 3 fixed by the side plates 2 at both ends of the assembly table 1 by an external manipulator, and the housing 5 and the bracket are clamped and fixed by adjusting the driving of the clamp 3;

[0036] Since grooves are provided on the inner sides of the clamps of the two groups of clamps 3, a fitting structure 8 is provided inside the grooves. When the clamps 3 drive the clamps to approach the housing 5 or the bracket, the housing 5 or the bracket first contacts and squeezes the multiple groups of pressing plates 87. The pressing plates 87 squeeze the springs 85, and the springs 85 squeeze the fixed plates 84. The fixed plates 84 automatically adjust the angles through the shafts, and the swinging plates 83 automatically adjust the swinging inclination according to the housing 5 or the bracket by rotating to the connected shafts. Since the surface of the housing 5 or the bracket is irregular, the multiple groups of pressing plates 87 automatically extend and retract to fit the surface according to the irregular surface of the housing 5 or the bracket, thereby fixing the housing 5 or the bracket more firmly.

[0037] When the housing 5 or the bracket is fixed by the clamp 3, the track and the alignment sensor of the alignment sensor component 4 are driven to start, and the screw holes of the housing 5 and the bracket are respectively corrected relative to each other, so that the clamp of the clamp 3 is fine-tuned, and the guide rail 9 is driven to make the correction structure 6 slidably connected to the top of the guide rail 9 adjust the position of the alignment screw hole. Due to the bottom plate 61 slidably connected to the top of the guide rail 9, the bidirectional motor 62 fixedly installed on the top of the bottom plate 61 is driven to start, and the bidirectional motor 62 drives the screw rods 63 at both ends to rotate. The screw rod 63 is threadedly connected to the sleeve 64, and the sleeve 64 drives the surface ring 65 to slide on the surface of the guide rod 66 Since the two sets of sleeves 64 are on the same horizontal line, the two sets of sleeves 64 align and correct the screw holes above the same horizontal line of the housing 5 and the bracket, so that the sleeves 64 move to both ends and penetrate the screw holes of the housing 5 and the bracket. If both sets of sleeves 64 can penetrate the screw holes, the alignment is successful. However, if the two sets of sleeves 64 do not penetrate the screw holes, the clamping plate of the clamp 3 can be adjusted so that the sleeves 64 can pass through the screw holes for correction. The automated correction reduces the waiting time and manual adjustment time during the assembly process, thereby significantly improving the production efficiency. In addition, the precise alignment reduces the rework rate caused by alignment errors, further improving the overall production efficiency.

[0038] When the screw holes of the outer shell 5 and the bracket of different sizes are to be corrected, the motor 73 arranged inside the shell 71 at one end of the sleeve 64 is started, and the motor 73 drives the gear 74 at the output end to mesh with the ring gear 75, and the ring gear 75 drives the driven plate 76 to rotate, and the driven plate 76 drives the four groups of equally spaced grooves 77 on the surface to rotate, so that the slider 78 inside the groove 77 slides from one end close to the center of the driven plate 76 to the other end, so that the slider 78 drives the slide plate 79 to slide straightly toward the outer end in the corresponding slide groove on the surface of the cross-shaped connecting plate 710, and the slide plate 79 drives the arc plate 711 to move toward the outer end in the groove 72, so that the arc plate 711 is adjusted according to the size of the screw hole, which is convenient for adjusting the screw holes of the outer shell 5 or the bracket of different sizes, and has high flexibility.
