Description

Technical Field

[0001] This invention relates to the field of automotive brake manufacturing technology, specifically to an automated brake caliper casting processing technology. Background Technology

[0002] Brake calipers are a key component of automotive brake systems. They are the parts that apply force to the brake discs. The hydraulic pressure generated by the master cylinder ultimately acts on the piston inside the caliper. As the piston expands, it pushes the brake pads against the brake disc, thus completing the braking action. Currently, the industry standard for brake caliper casting manufacturing processes typically involves separate steps such as grinding, inspection, and shot blasting. This process cannot be continuous, resulting in low automation and production efficiency. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and / or defects, and to provide at least the advantages described below.

[0004] The purpose of this invention is to provide an automated brake caliper casting processing technology. It utilizes a conveyor belt to connect an automatic grinding equipment and an appearance inspection area and a spheroidization rate inspection area. The first material box with a weighing function automates the transportation of brake caliper castings and also meets the needs of intermittent quantitative feeding in shot blasting machines.

[0005] To achieve these objectives and other advantages according to the present invention, an automated brake caliper casting processing technology is provided, comprising, in sequence along the forward direction of the production line, an automatic grinding device, a visual inspection area, a spheroidization rate inspection area, a first material bin, a shot blasting machine, and a second material bin; the specific steps are as follows:

[0006] Step 1: Feed 6-12 brake caliper castings into the feed port of the automatic grinding equipment at the same time. The automatic grinding equipment grinds the brake caliper castings. After grinding, the brake caliper castings are output one by one from the discharge port of the automatic grinding equipment to the upper surface of the conveyor belt.

[0007] Step two: The conveyor belt carries the brake caliper castings sequentially through the appearance inspection area and the spheroidization rate inspection area. The operator manually performs a visual inspection on each brake caliper casting, and then uses a handheld spheroidization rate detector to test the spheroidization rate of the brake caliper castings. Brake caliper castings that pass both the visual inspection and the spheroidization rate test are placed back on the upper surface of the conveyor belt and carried forward by the conveyor belt; unqualified products that fail both the visual inspection and the spheroidization rate test are placed in the waste bin.

[0008] Step 3: The brake caliper casting is carried by the conveyor belt to the top of the first material box and automatically falls into the first material box equipped with a weighing device. The weighing device measures the total weight of the brake caliper casting in the first material box in real time. After the set weight is reached, the conveyor belt stops conveying and the first material box carries the brake caliper casting therein to the shot blasting machine automatically.

[0009] Step 4: After the first material box reaches the feed port of the shot blasting machine, the caliper casting in the first material box is poured into the feed box of the shot blasting machine. Then, the emptied first material box automatically returns to the starting position, the conveyor belt starts conveying again, and the first material box continues to receive brake caliper castings.

[0010] Step 5: The feed box of the shot blasting machine pours the brake caliper casting into the feed port of the shot blasting machine, where it is shot blasted. After shot blasting, the brake caliper casting is output from the discharge port of the shot blasting machine to the second feed box. Once the second feed box is full of brake caliper castings, it is automatically transferred to the warehouse by an AGV trolley.

[0011] Preferably, the automatic polishing equipment rotates at a speed of 5,400 to 12,000 revolutions per minute.

[0012] Preferably, in step four, after the first material box reaches the feed port of the shot blasting machine, the clamp casting in the first material box is poured into the feed box of the shot blasting machine with the assistance of the automatic tilting mechanism.

[0013] Preferably, the shot blasting machine has a shot blasting capacity of 0.5 tons per shot and a shot blasting time of 10-20 minutes.

[0014] Preferably, the automatic grinding equipment is located on one side perpendicular to the forward direction of the conveyor belt, and a robot is located on the other side of the automatic grinding equipment. After grinding, the brake caliper castings are picked up one by one by the robot from the discharge port of the automatic grinding equipment and output to the upper surface of the conveyor belt.

[0015] The present invention has at least the following beneficial effects: The present invention utilizes a conveyor belt to connect the automatic grinding equipment and the appearance inspection area and the spheroidization rate inspection area, so as to realize the continuous production of the two inspection and processing processes of grinding and appearance inspection and spheroidization rate inspection of brake caliper castings. The first material box with weighing function automates the transportation of brake caliper castings from the inspection area to the shot blasting machine, and also meets the needs of intermittent quantitative feeding of shot blasting machine.

[0016] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0017] Figure 1 This is a flowchart of an automated brake caliper casting machining process according to the present invention. Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0019] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0020] like Figure 1 As shown, an automated brake caliper casting processing technology includes an automatic grinding device, a visual inspection area, a spheroidization rate inspection area, a first material bin, a shot blasting machine, and a second material bin, arranged sequentially along the production line's forward direction; the specific steps are as follows:

[0021] Step 1: Feed 6-12 brake caliper castings into the feed port of the automatic grinding equipment at the same time. The automatic grinding equipment grinds the brake caliper castings. After grinding, the brake caliper castings are output one by one from the discharge port of the automatic grinding equipment to the upper surface of the conveyor belt.

[0022] Step two: The conveyor belt carries the brake caliper castings sequentially through the appearance inspection area and the spheroidization rate inspection area. The operator manually performs a visual inspection on each brake caliper casting, and then uses a handheld spheroidization rate detector to test the spheroidization rate of the brake caliper castings. Brake caliper castings that pass both the visual inspection and the spheroidization rate test are placed back on the upper surface of the conveyor belt and carried forward by the conveyor belt; unqualified products that fail both the visual inspection and the spheroidization rate test are placed in the waste bin.

[0023] Step 3: The brake caliper casting is carried by the conveyor belt to the top of the first material box and automatically falls into the first material box equipped with a weighing device. The weighing device measures the total weight of the brake caliper casting in the first material box in real time. After the set weight is reached, the conveyor belt stops conveying and the first material box carries the brake caliper casting therein to the shot blasting machine automatically.

[0024] Step 4: After the first material box reaches the feed port of the shot blasting machine, the caliper casting in the first material box is poured into the feed box of the shot blasting machine. Then, the emptied first material box automatically returns to the starting position, the conveyor belt starts conveying again, and the first material box continues to receive brake caliper castings.

[0025] Step 5: The feed box of the shot blasting machine pours the brake caliper casting into the feed port of the shot blasting machine, where it is shot blasted. After shot blasting, the brake caliper casting is output from the discharge port of the shot blasting machine to the second feed box. Once the second feed box is full of brake caliper castings, it is automatically transferred to the warehouse by an AGV trolley.

[0026] In another example, one implementation of the automated brake caliper casting processing technology involves using an automatic grinding machine with a rotation speed of 5400 to 12000 revolutions per minute. This method allows for thorough grinding of the brake caliper casting surface to meet the requirements of subsequent salt spray testing. Furthermore, this method is merely an illustrative example and is not limited thereto. When implementing this invention, various implementations can be tailored to the user's needs.

[0027] One implementation of the automated brake caliper casting processing technology in the above scheme is as follows: In step four, after the first material box arrives at the inlet of the shot blasting machine, the caliper casting in the first material box is poured into the feeding box of the shot blasting machine with the assistance of an automatic tilting mechanism. This scheme, utilizing the action of the automatic tilting mechanism to pour the caliper casting from the first material box into the feeding box of the shot blasting machine, further improves the automation level of the production line.

[0028] One implementation of the shot blasting machine in the above scheme is as follows: the shot blasting machine has a shot volume of 0.5 tons per blast and a shot blasting time of 10-20 minutes. Using this scheme, sharp corners or burrs formed on the surface of the ground caliper casting can be treated, creating compressive stress on the casting surface. This enhances the tensile strength, corrosion resistance, and fatigue strength of the casting, and can also correct thin-walled castings that have been twisted.

[0029] One implementation of the automated brake caliper casting processing technology in the above scheme is as follows: the automatic grinding equipment is set on one side perpendicular to the forward direction of the conveyor belt, and a robot is set on the other side opposite the automatic grinding equipment. After grinding, the brake caliper castings are picked up one by one by the robot from the discharge port of the automatic grinding equipment and output to the upper surface of the conveyor belt. With this scheme, the automatic grinding equipment and the robot are positioned on opposite sides of the conveyor belt, facilitating the robot to pick up and output the castings one by one from the discharge port of the automatic grinding equipment to the conveyor belt.

[0030] The number of devices and processing scale described herein are for the purpose of simplifying the description of the invention. Applications, modifications, and variations of the invention will be readily apparent to those skilled in the art.

[0031] As described above, the present invention utilizes a conveyor belt to connect the automatic grinding equipment and the appearance inspection area and the spheroidization rate inspection area, thereby realizing continuous production of two inspection and processing processes for brake caliper castings: grinding, appearance inspection, and spheroidization rate inspection. The first material box with weighing function automates the transportation of brake caliper castings from the inspection area to the shot blasting machine, and also meets the needs of the shot blasting machine for intermittent quantitative feeding.

[0032] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Other modifications can be readily made by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and examples shown and described herein.
