Description

Technical Field

[0001] This utility model belongs to the field of casting repair technology, and more specifically, it relates to a device for repairing micro-defects on the surface of castings. Background Technology

[0002] During the production process, castings are prone to surface defects such as dents and scratches, and dust and impurities can easily remain at these defects.

[0003] The existing repair devices have the following problems: First, the dust in the dented areas of the casting is not thoroughly cleaned, which affects the bonding effect between the repair material and the casting, resulting in insufficient repair accuracy; second, the position adjustment flexibility of the repair mechanism is poor, making it difficult to cover micro-defects in different locations, thus limiting the repair range; third, the casting cannot be easily rotated after being fixed, which increases the operational difficulty of repairing multi-directional defects and reduces repair efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a device for repairing micro-defects on the surface of castings, thereby solving the problems of incomplete dust removal, limited repair range, and low repair efficiency of existing devices.

[0005] The purpose and effectiveness of this utility model's device for repairing micro-defects on the surface of castings are achieved through the following specific technical means: A device for repairing micro-defects on the surface of a casting includes a base; a rotating shaft is rotatably located at the center of the upper end face of the base, and a clamping seat is welded to one end of the rotating shaft. The clamping seat holds the casting, and auxiliary grooves are equidistantly provided on the outer wall of the clamping seat. A base block is fixed on the left side of the upper end face of the base, and a threaded rod is threadedly connected to the base block. A spring rod is rotatably connected to one end of the threaded rod, and the extended end of the spring rod is aligned with the auxiliary groove.

[0006] Furthermore, the auxiliary groove is a semi-cylindrical groove structure, and the protruding end of the spring rod is polished, resulting in an arc-shaped structure.

[0007] Furthermore, a first gear is welded onto the rotating shaft, a motor is fixed to the upper end face of the base, and a second gear is fixed to the output shaft of the motor, the second gear meshing with the first gear.

[0008] Furthermore, the rotating shaft, clamping seat, first gear, motor, second gear, auxiliary groove, base block, threaded rod and spring rod together form a drive assembly; a mounting block is fixed at the rear side of the upper end face of the base, and an air jet pipe is fixed on the mounting block. The air jet pipe is connected to an external air supply pump, and the air outlet of the air jet pipe is aligned with the casting.

[0009] Furthermore, a repair assembly is installed on the base. The repair assembly consists of an installation arm, a sliding seat, a first hydraulic cylinder, a guide rod, a scraper, and a second hydraulic cylinder. The installation arm is fixed to the right side of the upper end face of the base. A sliding seat slides on the installation arm. A first hydraulic cylinder is fixed on the installation arm, and the extended end of the first hydraulic cylinder is fixed on the sliding seat.

[0010] Furthermore, two guide rods slide symmetrically on the sliding seat, and the lower end of each guide rod is welded to the scraper block. A second hydraulic cylinder is fixed on the sliding seat, and the extended end of the second hydraulic cylinder is fixed to the scraper block. When the second hydraulic cylinder extends, the bottom surface of the scraper block contacts the upper surface of the casting.

[0011] Compared with the prior art, the present invention has the following beneficial effects: When the drive component of this application drives the casting to rotate, the spring rod and the auxiliary groove continuously and elastically engage to generate vibration, which loosens the dust in the recess. Combined with the air jet from the jet pipe, the dust is thoroughly cleaned, preventing impurities from affecting the adhesion of the repair material and improving the repair accuracy.

[0012] The repair component of this application uses a first hydraulic cylinder to drive a sliding seat to move along the mounting arm, a second hydraulic cylinder to control the lifting and lowering of the scraper, and two guide rods to ensure smooth movement of the scraper. It can quickly adapt to micro-defects in different locations of the casting and expand the repair coverage.

[0013] The motor in this application drives the casting to rotate via gear transmission, enabling multi-directional repair without the need for manual adjustment of the casting angle. The hydraulically driven repair mechanism responds quickly, simplifies the operation process, and significantly improves repair efficiency. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a device for repairing micro-defects on the surface of castings, including a base 1; a rotating shaft 201 is rotatably located at the center of the upper end face of the base 1, and a clamping seat 202 is welded to one end of the rotating shaft 201. The clamping seat 202 clamps the casting 3, and auxiliary grooves 206 are equidistantly opened on the outer wall of the clamping seat 202. A base block 207 is fixed at the left side of the upper end face of the base 1, and a threaded rod 208 is threadedly connected to the base block 207. A spring rod 209 is rotatably located at the right end of the threaded rod 208, and the protruding end of the spring rod 209 is aligned with the auxiliary groove 206. When the threaded rod 208 is rotated, the protruding end of the spring rod 209 is engaged in the auxiliary groove 206 under the threaded drive of the threaded rod 208. When the clamping seat 202 rotates, vibration can be generated through the continuous elastic engagement between the spring rod 209 and the auxiliary groove 206. This vibration can loosen the dust in the recessed area of ​​the casting 3, making it easier to clean the dust later, thus ensuring the accuracy of subsequent repair.

[0025] The rotating shaft 201 is welded with a first gear 203, and a motor 204 is fixed on the upper end face of the base 1. A second gear 205 is fixed on the output shaft of the motor 204. The second gear 205 meshes with the first gear 203, driving the motor 204 to rotate. Under the meshing transmission of the second gear 205 and the first gear 203, the rotating shaft 201 and the casting 3 can be rotated.

[0026] The drive assembly 2 is composed of a rotating shaft 201, a clamping seat 202, a first gear 203, a motor 204, a second gear 205, an auxiliary groove 206, a base block 207, a threaded rod 208, and a spring rod 209. A mounting block 4 is fixed to the rear side of the upper end face of the base 1. An air jet pipe 401 is fixed on the mounting block 4. The air jet pipe 401 is connected to an external air supply pump. The air outlet of the air jet pipe 401 is aligned with the casting 3. When the external air supply pump is started, gas is sprayed out through the air jet pipe 401 and comes into contact with the casting 3, thus cleaning the surface of the casting 3.

[0027] The base 1 is equipped with a repair component 5, which consists of an installation arm 501, a sliding seat 502, a first hydraulic cylinder 503, a guide rod 504, a scraper 505, and a second hydraulic cylinder 506. The installation arm 501 is fixed on the right side of the upper end face of the base 1. The sliding seat 502 slides on the installation arm 501. The first hydraulic cylinder 503 is fixed on the installation arm 501. The extended end of the first hydraulic cylinder 503 is fixed on the sliding seat 502.

[0028] Two guide rods 504 slide symmetrically on the sliding seat 502. The lower end of each guide rod 504 is welded to the scraper block 505. A second hydraulic cylinder 506 is fixed on the sliding seat 502. The extended end of the second hydraulic cylinder 506 is fixed to the scraper block 505. When the second hydraulic cylinder 506 extends, the bottom surface of the scraper block 505 contacts the upper surface of the casting 3. During repair, the repair material is applied to the surface of the casting 3, and the second hydraulic cylinder 506 is driven to extend until the scraper block 505 contacts the surface of the casting 3. During the repair process, the first hydraulic cylinder 503 is driven to extend and retract, which can expand the repair range.

[0029] Example 2: Based on Example 1, the motor 204 is electrically connected to an external power supply and is controlled by an external control switch; the first hydraulic cylinder 503 and the second hydraulic cylinder 506 are driven by an external hydraulic pump.

[0030] Working principle: In use, first fix the casting 3 to be repaired onto the clamping seat 202. Rotate the threaded rod 208 to make the protruding end of the spring rod 209 engage with the auxiliary groove 206. Start the motor 204, which, through the meshing of the first gear 203 and the second gear 205, drives the rotating shaft 201, the clamping seat 202, and the casting 3 to rotate. During rotation, the spring rod 209 and the auxiliary groove 206 elastically engage, generating vibration that loosens the dust in the recessed areas of the casting 3. Simultaneously, start the external air pump; air is ejected through the jet pipe 401, blowing the loosened dust into the dust collection box. Clean the surface of casting 3; after cleaning, turn off the air supply pump and apply repair material to the micro-defects of casting 3; drive the second hydraulic cylinder 506 to extend, so that the rubber pad on the bottom end of the scraper 505 contacts the surface of casting 3, and then drive the sliding seat 502 to move along the mounting arm 501 through the first hydraulic cylinder 503, and the scraper 505 moves accordingly and scrapes the repair material flat; if it is necessary to repair defects in different positions of casting 3, the motor 204 can be kept running, and the casting 3 can be rotated to a suitable angle and then stopped. Repeat the above repair operation until all micro-defects are repaired.
