Description
Technical Field
[0001] This invention relates to the field of automobile manufacturing technology, specifically to an automatic axle housing alignment device, which is suitable for automatically aligning and tightening the axle housing before machining the inner hole of the axle housing reinforcing ring and the large threaded hole. Background Technology
[0002] With the intensification of competition and technological updates in the automotive manufacturing industry, production line automation has become a direction for enterprise upgrading. Traditional production modes are difficult to meet the needs of large-scale production. Currently, before machining the inner hole of the reinforcing ring and the large threaded hole of the heavy truck axle housing, it is necessary to manually align the reinforcing ring of the axle housing to a vertical state and then press it. The degree of automation is low, the labor intensity of workers is high, the production time is long, and the processing quality of the axle housing is inconsistent. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic bridge housing alignment device.
[0004] The technical solution provided by this invention is: an automatic bridge housing alignment device, which is characterized in that it consists of a base plate, a clamping device, an alignment device, a connecting plate, a guide rail, a flange-type hydraulic cylinder and a third support base; The base plate is fixed with clamping devices on the left and right sides respectively. Each clamping device is equipped with a V-shaped iron and a clamping cylinder. The clamping cylinder is equipped with a pressure plate. The lower plane of the connecting plate is fixedly connected to the upper plane of the base plate. The upper plane of the connecting plate is provided with a groove, and the guide rail is fixed in the groove. The alignment device consists of a fixed plate, a support base assembly, a second support base, a swing-shaft hydraulic cylinder, a second pin, a second bushing, a rotating shaft, a third bushing, and a positioning plate. A slider is fixed to the lower plane of the fixed plate, and the slider has a groove that fits the guide rail with a clearance fit. A flanged hydraulic cylinder is fixed to the fixed plate, and the two are threaded together. The flanged hydraulic cylinder is fixed to the third support base. The extension and retraction of the flanged hydraulic cylinder on the third support base causes the slider to slide back and forth on the guide rail, simultaneously causing the alignment device to slide. The support base assembly, the second support base, and the third support base are fixed to the fixed plate. The second support base has two pin holes, and the two second bushings are interference-fitted with the two pin holes on the second support base. The cylindrical ends of the swing-shaft hydraulic cylinder are clearance-fitted with the inner holes of the second bushings. The positioning plate has two pin holes at each end. The two pin holes at one end are connected to the first pin of the support assembly with clearance fit, and the two pin holes at the other end are connected to the third bushing with interference fit. The two ends of the third pin are connected to the inner holes of the two third bushings with clearance fit. The rotating shaft has pin holes. The pin hole at one end of the rotating shaft is connected to the second pin with clearance fit, and the other end is connected to the swing shaft type hydraulic cylinder. The side of the positioning plate has two pin holes, and the two positioning pins are connected to the pin holes with interference fit. The swing shaft type hydraulic cylinder extends and drives the positioning plate to rotate counterclockwise around the first pin, so that the two positioning pins rotate to the upper and lower positions. At the same time, the flange type hydraulic cylinder retracts and drives the alignment device to slide close to the reinforcing rib surface of the axle housing, so as to correct the reinforcing ring surface of the axle housing to a vertical state. The clamping cylinder on the clamping device retracts and drives the pressure plate to clamp and fix the axle housing.
[0005] Furthermore, the support assembly consists of a first support, a first pin, and a first bushing; the first support has two pin holes, the two first bushings are interference-fitted with the two pin holes on the first support, and the outer circles at both ends of the first pin are clearance-fitted with the inner holes of the first bushings.
[0006] The beneficial effects of this invention are as follows: 1. By using V-shaped iron to support the outer circles of both ends of the axle housing, and driven by the swing shaft hydraulic cylinder and the flange hydraulic cylinder, the axle housing is automatically aligned and pressed before machining the inner hole of the reinforcing ring and the large threaded hole, ensuring that the axle housing is in a vertical state of the reinforcing ring during machining, reducing manual alignment actions and alignment time, and significantly reducing labor intensity; 2. It has a high degree of automation and high production efficiency, while ensuring the machining quality of the axle housing. Attached Figure Description

A flange-type hydraulic cylinder 25 is installed on the fixed plate 13, and the two are threaded together. The flange-type hydraulic cylinder 25 is fixed to the third support 23, and the extension and retraction of the flange-type hydraulic cylinder 25 fixed to the third support 23 drives the movement of the cylinder. The slider 12 slides back and forth on the guide rail 11, simultaneously driving the alignment device 3 to slide; the support base assembly 9, the second support base 16, and the third support base 23 are fixed to the fixing plate 13 with screws; the support base assembly 9 consists of a first support base 14, a first pin 15, and a first bushing 18. The first support base 14 has two pin holes, and the two first bushings 18 are interference-fitted with the two pin holes on the first support base 14. The outer circles of both ends of the first pin 15 are clearance-fitted with the first bushings 18 and the positioning plate 26; the positioning plate 26 has two pin holes on its side, and two positioning pins 2 4. With an interference fit between the pin holes, the flange-type hydraulic cylinder 25 retracts, causing the slider 12 to slide, and simultaneously causing the positioning pin 24 to approach the reinforcing ring surface of the axle housing; the second support seat 16 has two pin holes, and the two second bushings 19 are interference-fitted with the two pin holes. The left and right end cylinders of the swing shaft type hydraulic cylinder 17 are clearance-fitted with the inner holes of the second bushings 19; the positioning plate 26 has two pin holes at each end.

[0011] The present invention discloses an automatic bridge housing alignment device. After installation, the specific operation is as follows: Place the unmachined bridge housing with the inner hole of the reinforcing ring and the large threaded hole on the device. The outer circumferences at both ends of the bridge housing are placed on the two V-shaped surfaces of the left and right V-shaped blocks, with the reinforcing ring facing the alignment device. The left end face is pressed against the boss of the left V-shaped block (e.g., ...). Figure 1After the above operations are completed, activate the swing-shaft hydraulic cylinder. The swing-shaft hydraulic cylinder extends and drives the positioning plate to rotate counterclockwise around the first pin until the positioning pin is in an up-and-down position and stops. After the above operations are completed, activate the flange hydraulic cylinder. The flange hydraulic cylinder retracts and drives the slider to slide on the guide rail close to the axle housing reinforcing ring surface. The two positioning pins on the positioning plate press against the axle housing reinforcing ring surface, adjusting the entire axle housing reinforcing ring to a vertical position relative to the base plate. After the above operations are completed, rotate the pressure plate to above the outer circles at both ends of the axle housing and activate the clamping cylinder. The clamping cylinder retracts and drives the pressure plate to press the axle housing onto the V-block. After the above operations are completed, activate the flange hydraulic cylinder. The flange hydraulic cylinder extends and pushes the fixing plate to slide on the guide rail away from the axle housing reinforcing ring. After the above operations are completed, start the swing-shaft hydraulic cylinder. The swing-shaft hydraulic cylinder retracts, causing the positioning plate to rotate clockwise around the first pin to the lowest position. After the above operations are completed, start the equipment to complete the machining of the inner hole and large threaded hole of the axle housing reinforcing ring. After machining, start the clamping cylinder. The clamping cylinder extends, causing the pressure plate to loosen the axle housing. Then rotate the pressure plate to the outside of this device and lift the axle housing away. This completes the machining of the inner hole and threaded hole of one axle housing reinforcing ring. Then install the next workpiece and repeat the above cycle to complete the machining of the inner hole and threaded hole of the axle housing reinforcing ring in batches. By simply selecting the swing-shaft hydraulic cylinder with the specified stroke and making different V-blocks according to the height of the axle housing, it can be applied to different axle housing alignments.
