Description

Technical Field

[0001] The present invention relates to the technical field of brake disc conveying, and in particular to a conveying device for producing automobile brake discs. Background Art

[0002] Among existing published patents, the publication number CN222388936U, entitled "A Brake Disc Conveying Device," comprises a base having a rotating shaft rotatably mounted thereon, a first motor disposed on one side of the base for driving the rotating shaft, a conveying turntable with a plurality of frames mounted on its circumferential sidewalls disposed at the upper end of the rotating shaft, a support rod disposed oppositely at one end of the frame, one end of the support rod extending through the frame and fixedly connected to a drive block, and the other end fixedly connected to an arc-shaped holder; an electric push rod having a connecting plate mounted on its output shaft disposed within the frame, and a connecting rod rotatably connected between the connecting plate and the two drive blocks, with a connecting shaft fixedly mounted on either side of the connecting plate. This utility model brake disc conveying device achieves both clamping and conveying of the brake disc, significantly improving the positioning accuracy of the brake disc and facilitating improved spraying effects.

[0003] This device can avoid the slipping of the brake disc during transfer and transportation to a certain extent, and effectively improve the subsequent spraying effect; but when it is applied to petal-shaped brake discs, its clamping effect is obviously insufficient. Since the inner surface of the arc-shaped fixture is designed as a continuous arc, and the outer edge of the petal-shaped brake disc has a wavy concave-convex structure, the mismatch of this structure causes the arc-shaped fixture to only be able to form contact with a single crest (convex part), and the remaining crests and troughs (concave parts) cannot obtain effective support. This incomplete contact method will greatly reduce the clamping stability. In actual operation, it is easy to cause the brake disc to tilt or shift due to uneven force, which ultimately affects the subsequent spraying effect.

[0004] For this reason, a kind of automobile brake disc production conveying device is designed to solve the above-mentioned problem. Summary of the Invention

The upper end of the collecting box 9 is provided with a collecting port, and the trapezoidal rubber scraper 7 is fixedly mounted on the collecting port of the collecting box 9 through the mounting seat 35.

A telescopic hose 40 is fixedly connected to the left side of the collecting box 9. The upper ends of the two telescopic hoses 40 respectively pass through the outside of the rotating shaft 11 and are fixedly connected to the outside of the rotating tube 41. The rotating tube 41 is fixedly installed at the inner rotating groove of the rotating shaft 11 through a fixing plate. The bottom end of the rotating tube 41 is rotatably connected to a guide box 42. The bottom of the guide box 42 is fixedly installed at the inner bottom end of the fixed base 1 through a connecting base. The rear side of the guide box 42 is fixedly connected to a connecting pipe 43.

[0046] The rotating motor 21 is started, and the rotating motor 21 drives the rotating shaft 45 and the petal-shaped brake disc 46 fixed at the bottom end of the rotating shaft 45 to rotate counterclockwise. When the petal-shaped brake disc 46 passes through the paint spray nozzle, it is evenly sprayed with paint. Subsequently, when it passes through the area of ​​the trapezoidal rubber scraper 7, the fourth telescopic cylinder 32 is synchronously started. The fourth telescopic cylinder 32 drives the trapezoidal rubber scraper 7 to move along the extension of the petal-shaped brake disc 46. The trapezoidal rubber scraper 7 scrapes off the excess paint at the peak of the petal-shaped brake disc 46. The paint is then directed to the collection box 9 through the inclined guide plate 44 for recycling and reuse. At the same time, the paint replenishing pipe connected to the left end of the connecting pipe 43 continuously delivers an appropriate amount of paint to the collection box 9. The paint spraying motor 48 drives the gear pump 38 to work. The gear pump 38 delivers the paint in the collection box 9 to the conduit 36 ​​through the suction pipe 39 and the delivery pipe 37. The conduit 36 ​​then uses multiple replenishing nozzles 8 to perform paint touch-up operations on the troughs of the petal-shaped brake disc 46, and the trapezoidal rubber scraper 7 is used to scrape it flat at the same time.

[0047] During use, the device is placed between the petal-shaped brake disc 46 conveyor belt and the paint spraying device, and the first telescopic cylinder 15 is started, which drives the support frame 16 to move horizontally until the stable clamping mechanism is located directly above the petal-shaped brake disc 46 on the conveyor belt. Subsequently, the second telescopic cylinder 17 is started, which drives the movable frame 2 and the stable clamping mechanism to move downward until the two support plates 5 are fully inserted into the middle mounting hole of the petal-shaped brake disc 46;

[0048] Next, the first motor 24 is started, and the first motor 24 drives the middle second gear 23 to rotate 90 degrees clockwise. The middle second gear 23 then drives the two second gears 23 on the front and right sides to rotate counterclockwise respectively, so that the two support shafts 22 respectively drive the two support plates 5 to rotate outward to a horizontal state, and the second telescopic cylinder 17 is started again to drive the support plates 5 to move upward until their upper surfaces are close to the upper ends of the inner sides of the petal-shaped brake discs 46. At the same time, the two third telescopic cylinders 25 and the two second motors 29 are started, and the two third telescopic cylinders 25 drive the two groups of support rollers 6 to move outward. The two second motors 29 respectively drive the two connecting shafts 28 and the two groups of support rollers 6 connected by the rotating member 30 to rotate outward, so that the two groups of support rollers 6 are respectively supported on the inner walls of the petal-shaped brake discs 46.

[0049] Afterwards, the drive motor 12 is started, which drives the right first gear 10 to rotate. The right first gear 10 then drives the meshed left first gear 10 to rotate, thereby driving the rotating shaft 11 to rotate, and then driving the rotating disk 13 and the right mechanism and the petal-shaped brake disc 46 to rotate as a whole, transferring them to the painting area. Since the spraying trajectory of the paint spray nozzle is usually uniform, it is easy for too much paint to accumulate at the crest of the petal-shaped brake disc 46, resulting in an excessively thick paint film, which may cause sagging; and the trough of the wave is concave, which makes it difficult for the paint to be fully covered, which may result in the bottom being exposed or leaking. Therefore, before the painting operation is carried out, the fourth telescopic cylinder 32 and the fifth telescopic cylinder 34 are first started to drive the trapezoidal rubber scraper 7 to move backward and downward to the outside of the petal-shaped brake disc 46;

[0050] The existing painting device is generally equipped with two nozzles at the front and back, one of which is a paint spray nozzle for spraying paint on the petal-shaped brake disc 46; the other is a drying nozzle for synchronously drying the petal-shaped brake disc 46 after painting. The rotary motor 21 is started, and the rotary motor 21 drives the rotating shaft 45 and the petal-shaped brake disc 46 supported and fixed at the bottom end of the rotating shaft 45 to rotate counterclockwise. When the petal-shaped brake disc 46 passes through the paint spray nozzle, it is evenly sprayed with paint. Then, when it passes through the area of ​​the trapezoidal rubber scraper 7, the fourth telescopic cylinder 32 is synchronously started. The fourth telescopic cylinder 32 drives the trapezoidal rubber scraper 7 to move along the extension of the petal-shaped brake disc 46. The trapezoidal rubber scraper 7 scrapes off the excess paint at the peaks of the petal-shaped brake disc 46, and the excess The paint is then directed to the collection box 9 through the inclined guide plate 44 for recycling and reuse. At the same time, the paint replenishing pipe connected to the left end of the connecting pipe 43 continuously delivers an appropriate amount of paint to the collection box 9. The paint spraying motor 48 drives the gear pump 38 to work. The gear pump 38 delivers the paint in the collection box 9 to the conduit 36 ​​through the suction pipe 39 and the delivery pipe 37. The conduit 36 ​​then uses multiple replenishing nozzles 8 to perform paint touch-up operations on the troughs of the petal-shaped brake disc 46, and the trapezoidal rubber scraper 7 is used to scrape the paint flat at the same time.

[0051] When the outer side of the petal-shaped brake disc 46 is painted and dried, the first telescopic cylinder 15 is started. The first telescopic cylinder 15 drives the stabilizing clamping mechanism and the petal-shaped brake disc 46 to move backward and out of the spraying area. The worker removes it and resets the stabilizing clamping mechanism. Then, the flip motor 20 is started. The flip motor 20 drives the flip seat 19 and the mechanism thereon to flip upward 180 degrees as a whole. The above fixing operation is repeated. The worker places the petal-shaped brake disc 46 on the two support plates 5. At the same time, the two sets of support rollers 6 clamp its outer side. The second telescopic cylinder 17 is started again.
