Description

Technical Field

[0001] The invention relates to the technical field of forging inspection, in particular to a rapid correction inspection tool for automobile flanges. Background Art

[0002] In automobile forging production, forgings often bend, twist and other deformations during forging, cooling, trimming, punching, heat treatment and other processes and their transfer due to uneven cooling, local stress, collision and other reasons; some forgings, such as forgings with thin flanges, are more likely to have this situation due to their shape characteristics. If this deformation exceeds the allowable range of the forging technical conditions, the forging will be scrapped. Correction is to correct this deformation so that the shape and size of the forging meet the requirements.

[0003] Traditional calibration often involves placing the flange on a fixed stamping table, and then using a steel fork or other tool to adjust the position of the flange to ensure that the top calibration die is just above the flange to be calibrated, and then the die is dropped to perform a stamping calibration. During the calibration process, the staff also needs to constantly use tools to adjust the specific position of the flange, which is very laborious and requires a huge workload. In addition, the manually adjusted flange position is not accurate, which often results in a large disc thickness error and uneven disc surface, affecting the processing quality of the product. To this end, we propose a quick calibration fixture for automotive flanges. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that the position adjustment of automobile forging flanges is relatively troublesome during the calibration process, the accuracy of the disc surface calibration is not high, and the product quality is poor, and a rapid calibration fixture for automobile flanges is proposed.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] In this embodiment, refer to Figure 1-6 The automobile flange quick calibration fixture comprises a base 1, which is a round table. A round pad 2 is arranged on the table of the base 1. The base 1 and the pad 2 are arranged concentrically. A fixing column 3 is arranged at the center of the table of the pad 2. The base 1, the pad 2 and the fixing column 3 are designed as an integrated whole. Figure 3 The fixed column 3 has a plurality of notch grooves 301 on its outer wall, and the notch grooves 301 are circumferentially arranged. The notch grooves 301 are located at the lower half of the column body of the fixed column 3. The pad 2 is provided with a circle of adjustment platforms 4 outside the fixed column 3. Figure 2 The number of the adjustment platforms 4 is the same as the number of the notched slots 301. The adjustment platforms 4 are arranged one by one with the notched slots 301. A connector 403 is provided at the front end of the adjustment platform 4. The adjustment platform 4 is rotatably installed in the notched slots 301 through the rotating shaft on the connector 403. The adjustment platforms 4 are arranged radially, and gaps are maintained between adjacent adjustment platforms 4. In addition, a slope 402 is provided on the surface of the adjustment platform 4 facing the fixed column 3. The purpose of providing the slope 402 is that when the adjustment platform 4 rotates, it will not be restricted by its own structure. In this way, the rotation of each adjustment platform 4 can be relatively independently controlled and adjusted.

[0026] A plurality of radially distributed slide grooves 302 are provided on the surface of the pad 2. The slide grooves 302 are located below the adjustment platform 4. The slide grooves 302 correspond to the adjustment platform 4 one by one. A guide groove 401 is provided at the corresponding position of the adjustment platform 4 toward the slide groove 302. The top wall of the guide groove 401 at the bottom of the adjustment platform 4 is composed of a horizontal surface 401a and an inclined surface 401b. A push block 5 is slidably matched in the slide groove 302. The top of the push block 5 is slidably matched with the guide groove 401. The push block 5 slides in the direction close to or away from the center of the fixed column 3. A smooth push surface 501 is provided on the upper half of the side of the push block 5 facing the fixed column 3. The push surface 501 contacts the bottom surface of the adjustment platform 4. In this way, as the push block 5 moves in the slide groove 302, the top of the push block 5 gradually slides along the horizontal surface 401a toward the inclined surface 401b, and the adjustment platform 4 is gradually lifted up, so that it rotates to a certain angle.

[0027] The base 1 is provided with a plurality of identical push cylinders 8 along its edge, and the push cylinders 8 correspond to the adjustment platform 4 one by one. The output end of the push cylinder 8 is provided with a push telescopic rod 6, which is radially arranged, and the end of the push telescopic rod 6 passes through the concave groove 303 and docks on the push block 5. In addition, as shown in the attached Figure 3 As shown, the tabletop of the pad 2 is provided with a radial concave groove 303 on the side of the slide groove 302 away from the fixed column 3. The concave groove 303 is used to insert and place the push telescopic rod 6. The push cylinder 8 is installed on the support frame 7. The support frame 7 is located on the tabletop of the base 1. The push cylinder 8 pushes the push block 5 to slide in the slide groove 302, thereby achieving the purpose of adjusting the lifting angle of the adjustment table 4. Finally, a correction die 9 for correcting the workpiece is arranged above the base 1.

[0028] Specific working process: Under normal circumstances, each adjustment platform 4 is placed on the pad 2, and the table tops of each adjustment platform 4 are kept horizontal, and the table tops of all adjustment platforms 4 are on the same horizontal plane. At this time, the flange to be calibrated is inserted on the adjustment platform 4 along the fixing column 3. If the disk surface of the flange is completely in full contact with the adjustment platform 4 corresponding to its bottom, it can be considered that the disk surface of the flange is well formed; when the disk surface of the flange is not well formed, the disk surface of the flange is uneven. Once a certain area of ​​the disk surface does not fit with the surface of the adjustment platform 4 at the corresponding position at the bottom, the adjustment process can be started. The pushing cylinder 8 outside the adjusting platform 4 controls the pushing block 5 to slide along the slide groove 302 toward the center position by pushing the cylinder 8. The pushing block 5 continuously pushes up the adjusting platform 4 on its top during the sliding process, so as to achieve the purpose of gradually fitting the adjusting platform 4 to the bottom surface of the flange. After the position of the adjusting platform 4 is adjusted, the correction die 9 is finally started to move downward and act on the surface of the flange. Since the surface of the flange is fully fitted with the adjusting platform 4 at the bottom at this time, the falling correction die 9 can fully press the flange, making its surface smoother and significantly improving the processing quality of the product.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
