Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing, and in particular to a vehicle axle housing transfer frame. Background Technology

[0002] The domestic axle industry prioritizes high efficiency and low cost in meeting the precision requirements for axle housing machining surfaces and the overall appearance quality requirements. Employing efficient, practical, and economical tooling is crucial for improving production efficiency and ensuring product quality. Appropriate tooling can significantly reduce the probability of axle housing failure modes, decrease subsequent rework and repairs, improve production efficiency, reduce production cycle time, and guarantee product quality.

[0003] Currently, there are many types of drive axle housings in China. The axle housings need to be transferred between processes. During the actual transfer stage, there is a phenomenon of collision between the machined surfaces of the axle housing and shaft head and the transfer frame, which affects the subsequent production accuracy and appearance quality of the axle housing.

[0004] To address this issue, a vehicle axle housing transfer frame is proposed, which has the advantage of preventing collisions between the axle housing and the machined surfaces of the axle head, thereby solving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vehicle axle housing transfer frame.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle axle housing transfer frame, comprising a frame body, a bearing plate welded to the inner side of the frame body, and a plurality of spherical mounting holes equally spaced on the top surface of the bearing plate, each of the spherical mounting holes being provided with an axle housing body, U-bolts being inserted and installed at the two side edges of the bearing plate corresponding to the spherical mounting holes, and arc-shaped pads connected to the shaft of the axle housing body being provided on the U-bolts, both ends of the U-bolts being provided with threaded heads, the portion of the threaded head passing through the bearing plate being threadedly connected to a wing nut, guide frames being welded to the lower surfaces of the front and rear ends of the frame body, and handles being welded to the upper surfaces of the front and rear ends of the frame body, an adjusting block being slidably installed in the guide frame, and a roller being rolledly installed at the bottom of the adjusting block.

[0007] As a further description of the above technical solution: the guide frame has a U-shaped cross-section, and a dovetail groove is provided on the inner side of the guide frame. A dovetail block is provided on the left side wall of the adjusting block and is slidably connected to the dovetail groove. A positioning post is inserted and installed on the right side wall of the adjusting block. A spring is installed in the cavity inside the adjusting block, and one end of the spring abuts against a support block. The side of the support block away from the spring is connected to the positioning post. An adjusting port is provided on the top surface of the adjusting block and communicates with its inner cavity. An upper through hole and a lower through hole are provided on the lower surface of the guide frame from top to bottom. The positioning post extends to the inner side of the upper through hole of the guide frame. An adjusting post is fixed on the side of the support block, and the adjusting post extends through the adjusting port to the outside of the adjusting block.

[0008] As a further description of the above technical solution: the bearing plate is provided with multiple sets of U-bolts and spherical mounting holes at equal intervals, and each set of U-bolts and spherical mounting holes forms a mounting position for the main body of the bridge shell.

[0009] As a further description of the above technical solution: mounting holes are provided at the edge of the surface of the bearing plate corresponding to the U-bolts, and the ratio of the number of mounting holes to the number of U-bolts is 2:1.

[0010] As a further description of the above technical solution: the diameter of the positioning post matches the inner diameter of the upper through hole and the lower through hole, and a spherical part is provided at the end of the positioning post away from the support block.

[0011] As a further description of the above technical solution: the arc pad has an arc groove, and the size of the arc groove matches the axial size of the bridge housing body.

[0012] This utility model has the following beneficial effects:

[0013] In this utility model, multiple sets of U-bolts and spherical mounting holes are equidistantly installed on the support plate of the frame. Each set of U-bolts and spherical mounting holes forms a bridge housing body mounting station. By setting the convex spherical surface of the bridge housing body towards the spherical mounting hole and making the shaft part at both ends of the bridge housing body contact the arc pad of the U-bolt, the U-bolt is tightened by rotating the wing nut installed at the two threaded heads of the U-bolt. This makes the shaft part at both ends of the bridge housing body reliably connected to the arc pad of the corresponding U-bolt, and the spherical mounting hole is used to position the convex spherical surface of the bridge housing body. On the one hand, the bridge housing body is reliably locked, and on the other hand, collisions are avoided between the machined surface of the bridge housing and the shaft head and the transfer frame.

[0014] In this invention, a set of guide frames is set in pairs at the front and rear ends of the frame, and an adjusting block with a roller is slidably installed in each guide frame. By pushing the adjusting column to move in the adjusting port, the adjusting column causes the supporting block to compress the spring in the inner cavity of the adjusting block, thereby causing the supporting block to disengage the positioning column from the upper through hole. At this time, as the dovetail block on the side of the adjusting block slides with the dovetail groove on the inner side of the guide frame, when the positioning column descends to the position of the lower through hole, the force applied to the adjusting column is released, allowing the spring to return to its original position and push the positioning column to engage with the lower through hole until the roller of the adjusting block extends out of the guide frame, thus meeting the needs of frame movement and turnover.

Adjustment blocks 8 are slidably installed in the guide frames 7, and rollers 21 are rolled on the bottom of the adjustment blocks 8. In order to facilitate the adjustment of the U-bolt 5, the height of the bearing plate is greater than the length of the thread head 11 of the U-bolt 5, and the height of the bearing plate 2 is higher than the height of the bottom of the frame 1. In order to meet the batch transfer requirements of the production line, several bearing plates 2 can also be stacked on the frame 1.

[0023] In one embodiment, the guide frame 7 has a U-shaped cross-section, and a dovetail groove 14 is provided on the inner side of the guide frame 7. A dovetail block 13 is provided on the left side wall of the adjusting block 8 and is slidably connected to the dovetail groove 14. A positioning post 9 is inserted and installed on the right side wall of the adjusting block 8. A spring 15 is installed in the cavity inside the adjusting block 8, and one end of the spring 15 abuts against a support block 16. The side of the support block 16 facing away from the spring 15 is connected to the positioning post 9. An adjusting port 18 communicating with its inner cavity is provided on the top surface of the adjusting block 8. An upper through hole 19 and a lower through hole 20 are provided on the lower surface of the guide frame 7 from top to bottom. The positioning post 9 extends to the inner side of the upper through hole 19 of the guide frame 7. An adjusting post 17 is fixed on the side of the support block 16, and the adjusting post 17 extends to the outside of the adjusting block 8 through the adjusting port 18.

[0024] In one embodiment, multiple sets of U-bolts 5 and spherical mounting holes 10 are equidistantly arranged on the bearing plate 2, and each set of U-bolts 5 and spherical mounting holes 10 forms a mounting position for the bridge shell body 4. The multiple sets of U-bolts 5 and spherical mounting holes 10 facilitate the equidistant mounting of the bridge shell body 4 and avoid collisions.

[0025] In one embodiment, mounting holes are provided at the edge of the surface of the bearing plate 2 corresponding to the U-bolts 5, and the ratio of the number of mounting holes to the number of U-bolts 5 is 2:1, that is, each U-bolt 5 has two mounting holes.

[0026] In one embodiment, the diameter of the positioning post 9 matches the inner diameter of the upper through hole 19 and the lower through hole 20, and the end of the positioning post 9 away from the support block 16 is provided with a spherical part.

[0028] Working principle:

[0029] In use, first, align the spherical protrusion of the axle housing body 4 with the spherical mounting hole 10, and make the shaft portions at both ends of the axle housing body 4 contact the arc-shaped pads 6 of the U-bolts 5.

The spherical protrusion of the axle housing body 4 is positioned through the spherical mounting hole 10, thus installing the axle housing body 4. Simultaneously, by pushing the adjusting column 17 into the adjusting port 18... The movement causes the adjusting column 17 to drive the support block 16 to compress the spring 15 in the inner cavity of the adjusting block 8, thereby causing the support block 16 to drive the positioning column 9 to disengage from the upper through hole 19. At this time, as the dovetail block 13 on the side of the adjusting block 8 slides with the dovetail groove 14 on the inner side of the guide frame 7, when the positioning column 9 descends to the position of the lower through hole 20, the force applied to the adjusting column 17 is released, so that the spring 15 returns to its original position and pushes the positioning column 9 to engage with the lower through hole 20, until the roller 21 of the adjusting block 8 extends out of the guide frame 7 to meet the needs of the frame 1 for movement and turnover.
