Description

Technical Field

[0001] This utility model relates to the field of universal joint technology, specifically to a shot blasting equipment for surface strengthening treatment of universal joint cross shafts. Background Technology

[0002] Universal joint cross shafts are core components in mechanical transmissions used to connect non-collinear shafts. They consist of a cross-shaped bearing housing and four radially symmetrical journals. Their core function is to transmit power when the included angle between two shafts changes, while compensating for axial, radial, and angular deviations to ensure smooth torque transmission. This structure uses the rotation of the hinge point to offset axial offset and is widely used in automotive transmission systems, industrial equipment, and marine propulsion systems. Universal joint cross shafts are characterized by their compact structure, high load-bearing capacity, and wear resistance, but they require regular lubrication to reduce friction loss. Variations can further eliminate speed fluctuations and improve transmission efficiency.

[0003] When universal joint cross shafts are shot blasted, traditional shot blasting machines, in order to ensure the precision of the parts, often do not stack the universal joints together for processing, but can only perform shot blasting on the universal joints individually. However, when there are many universal joints, this processing method will result in low efficiency. Based on this, this utility model designs a shot blasting device for surface strengthening treatment of universal joint cross shafts to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a shot blasting device for surface strengthening treatment of universal joint cross shafts, so as to solve the problem mentioned in the background art that universal joints cannot achieve both processing accuracy and processing efficiency during shot blasting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shot blasting device for surface strengthening treatment of a universal joint cross shaft, comprising a shot blasting device housing, a shot blasting box fixed to the top surface of the shot blasting device housing, an impeller inside the shot blasting box, a first servo motor fixed to one side of the shot blasting box, the output end of the first servo motor being fixedly connected to the impeller inside the shot blasting box, a second servo motor fixed to the side of the shot blasting device housing near the first servo motor, a rotating wheel fixed to the output end of the second servo motor, the rotating wheel being rotatably disposed inside the shot blasting device housing, a plurality of connecting arms fixed to the outer side of the rotating wheel, a fixing plate fixed to the end of each connecting arm away from the rotating wheel, two fixing ports symmetrically fixed to the end of each fixing plate away from the rotating wheel, a fixing bolt threadedly connected to the outer side of each fixing port, a sealing structure provided on one side of the shot blasting device housing, and a recovery port opened at the bottom of the shot blasting device housing.

[0006] Preferably, the sealing structure includes a rotating shaft, and the rotating shaft is fixed on the top and bottom surfaces of one side of the shot blasting equipment housing. An upper sealing plate and a lower sealing plate are respectively provided on one side of the shot blasting equipment housing. The top end of the upper sealing plate is rotatably connected to the upper rotating shaft, and the bottom end of the lower sealing plate is rotatably connected to the lower rotating shaft. The upper sealing plate and the lower sealing plate are fixedly connected to the shot blasting equipment housing through a snap-fit ​​structure.

[0007] Preferably, the connecting arms are fixed at equal intervals on the rotating wheel, and each pair of adjacent connecting arms is perpendicular to each other.

[0008] Preferably, the fixing bolt is an embedded hexagonal bolt, and the width of the top surface of the fixing bolt is smaller than the width of the fixing opening.

[0009] Preferably, the snap-fit ​​structure includes snap-fit ​​blocks, and snap-fit ​​blocks are fixed to the sides of both the upper and lower sealing plates. Two snap-fit ​​plates are rotatably connected to one side of the shot blasting equipment housing, and the snap-fit ​​blocks are snapped into the inside of the snap-fit ​​plates.

[0010] Preferably, the height of the upper sealing plate is the same as the height of the lower sealing plate, and the height between the opposite surfaces of the upper and lower sealing plates is the same as the height of the connecting arm.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) This utility model solves the problem mentioned in the background art that the universal joint cannot solve the problem of simultaneous processing accuracy and processing efficiency when shot blasting.

[0013] (2) By setting an upper sealing plate and a lower sealing plate on one side of the shot blasting equipment shell, and rotating the upper sealing plate and the lower sealing plate to the shot blasting equipment shell via a rotating shaft, when the shot blasting box is working, the shot blasting equipment shell prevents the shot inside the shot blasting equipment shell from being thrown out by closing the upper sealing plate and the lower sealing plate. At the same time, when the upper sealing plate and the lower sealing plate are closed, the operator can replace the universal joint that has been treated on the fixed port exposed on the outside of the shot blasting equipment shell. This allows the universal joint to be treated while being shot blasted through the shot blasting equipment shell, and the treated universal joint can be recovered and replaced at the same time, thus improving the efficiency of shot blasting.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a shot blasting device for surface strengthening treatment of universal joint cross shafts, including a shot blasting device shell 1, a shot blasting box 2 fixed on the top surface of the shot blasting device shell 1, an impeller inside the shot blasting box 2, a first servo motor 3 fixed on one side of the shot blasting box 2, the output end of the first servo motor 3 fixedly connected to the impeller inside the shot blasting box 2, a second servo motor 4 fixed on the side of the shot blasting device shell 1 near the first servo motor 3, a rotating wheel 5 fixed on the output end of the second servo motor 4, the rotating wheel 5 rotatably disposed inside the shot blasting device shell 1, a plurality of connecting arms 6 fixed on the outer side of the rotating wheel 5, a fixing plate 7 fixed on the end of each connecting arm 6 away from the rotating wheel 5, two fixing ports 8 symmetrically fixed on the end of each fixing plate 7 away from the rotating wheel 5, a fixing bolt 9 threadedly connected to the outer side of each fixing port 8, a sealing structure on one side of the shot blasting device shell 1, and a recovery port 15 opened at the bottom of the shot blasting device shell 1, and shot blasting treatment is performed simultaneously by multiple separations of the universal joint through the connecting arms 6.

[0023] Among them, the connecting arms 6 are fixed at equal intervals on the rotating wheel 5, and each two adjacent connecting arms 6 are perpendicular to each other. The fixing bolts 9 are embedded hexagonal bolts, and the width of the top surface of the fixing bolts 9 is smaller than the width of the fixing opening 8 to avoid mutual interference between adjacent fixing bolts 9.

[0024] Please see Figure 1-4 The sealing structure includes a rotating shaft 10. The rotating shaft 10 is fixed on the top and bottom surfaces of one side of the shot blasting equipment shell 1. An upper sealing plate 11 and a lower sealing plate 12 are respectively provided on one side of the shot blasting equipment shell 1. The top end of the upper sealing plate 11 is rotatably connected to the upper rotating shaft 10, and the bottom end of the lower sealing plate 12 is rotatably connected to the lower rotating shaft 10. The upper sealing plate 11 and the lower sealing plate 12 are fixedly connected to the shot blasting equipment shell 1 through a snap-fit ​​structure, so that the shot blasting equipment shell 1 seals the side of the shot blasting equipment shell 1 through the upper sealing plate 11 and the lower sealing plate 12.

[0025] The snap-fit ​​structure includes snap-fit ​​blocks 13. Snap-fit ​​blocks 13 are fixed to the sides of both the upper sealing plate 11 and the lower sealing plate 12. Two snap-fit ​​plates 14 are rotatably connected to one side of the shot blasting equipment housing 1. The snap-fit ​​blocks 13 are snapped into the inside of the snap-fit ​​plates 14. The height of the upper sealing plate 11 is the same as the height of the lower sealing plate 12. The height between the opposite surfaces of the upper sealing plate 11 and the lower sealing plate 12 is the same as the height of the connecting arm 6, thereby improving the sealing of the shot blasting equipment housing 1.

[0026] The overall working principle is as follows: by opening the locking blocks 13, the two locking blocks 13 are released from fixing the upper sealing plate 11 and the lower sealing plate 12. At the same time, the operator inserts one end of the universal joint into the fixing port 8 and turns the fixing bolt 9 with a hex wrench to fix the universal joint inside the fixing port 8. At this time, by lifting the upper sealing plate 11 to prevent it from blocking the movement of the connecting arm 6, the second servo motor 4 is started, causing the rotating wheel 5 to rotate. The rotating wheel 5 then moves the connecting arm 6, causing the connecting arm 6 to move into the shot blasting equipment shell 1. At this time, the other connecting arm 6 passes through the lower part of the shot blasting equipment shell 1. The machine moves to one side of the shot blasting equipment housing 1. At this time, the upper sealing plate 11 and the lower sealing plate 12 are closed, and the locking block 13 is locked and fixed by the locking plate 14, so that the upper sealing plate 11 and the lower sealing plate 12 are fixedly connected to the shot blasting equipment housing 1 through the locking plate 14. Then, the first servo motor 3 is started, so that the first servo motor 3 drives the impeller inside the shot blasting box 2 to rotate, and then the shot is put into the shot blasting box 2. At this time, the impeller drives the shot to perform shot blasting treatment on the universal joint inside the shot blasting equipment housing 1. At this time, the operator can fix the untreated universal joint inside other fixing ports 8 in the above manner. The shot after shot blasting is discharged through the recovery port 15 and recycled.
