Description

Technical Field

[0001] This utility model relates to the technical field of bridge housing processing limiting equipment, specifically, to a limiting device for bridge housing processing. Background Technology

[0002] In the machining of axle housings, precise positioning and reliable clamping are crucial for ensuring machining accuracy and quality. Traditional axle housing machining fixtures have several shortcomings. For example, some fixtures use a single positioning method, making it difficult to adapt to the positioning requirements of axle housings of different specifications, resulting in significant machining errors; the clamping structure of some fixtures is not stable enough, allowing the axle housing to easily shift during machining, affecting machining accuracy; and some fixtures are complex to operate, with long loading and unloading times for axle housings, reducing production efficiency. To solve these problems, there is an urgent need for a new type of more efficient and practical limiting pivot for axle housing machining. Utility Model Content

Through the cooperation of the support shaft, limiting frame, limiting rod, set screw and positioning block in the end limiting assembly, this invention can accurately limit the two ends of the axle housing, ensure that the position of the axle housing is fixed during the processing, and effectively improve the processing accuracy.

[0004] A limiting device for axle housing processing includes a base with a plurality of mounting holes. End limiting components are respectively provided at both ends of the upper side of the base. Each end limiting component includes a support column, a positioning block, a set screw, a limiting rod, a slot, and a support shaft. The slots are in pairs and are respectively fixed to one end of the base. Each pair of slots can engage both ends of the support shaft. The support shaft and a connecting block are fixedly connected. A limiting frame is fixedly connected to the connecting block. The connecting block is fixed to both ends of the limiting frame. The two limiting frames can limit the two ends of the axle housing.

[0005] Each of the limiting frames is rotatably connected to the limiting rod, and the other end of the limiting rod is threadedly connected to a set screw. The set screw can abut against the positioning block. The positioning block is fixed to one side of the support column, and the support column is fixed to the base.

[0006] Furthermore, the end of the limiting frame corresponding to the bridge housing is made of soft rubber.

[0007] Furthermore, the base is also provided with a lower support member, which is installed on the base by bolts and nuts.

[0008] Furthermore, support plates are fixedly installed on both sides of the upper part of the base. There are two sets of support plates, and each set is evenly arranged. The fixed end of the linear track is fixedly connected to the support plate. The movable end of all the linear tracks is fixedly connected to the moving rod. The moving rod is fixedly connected to the abutment block. The abutment block can abut against the lower outer side of the bridge shell.

[0009] Furthermore, symmetrical guide blocks are fixedly connected to the upper parts of both sides of the base, and the guide blocks are passed through by electric push rod telescopic rods.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0024] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described in terms of the embodiments and implementation methods.

[0025] The specific embodiments of this utility model are as follows:

[0026] A limiting device for axle housing processing includes a base 5 with a plurality of mounting holes. End limiting components are respectively provided at both ends of the upper side of the base 5. Each end limiting component includes a support column 10, a positioning block 11, a set screw 13, a limiting rod 12, a slot 14, and a support shaft 151. There are two pairs of slots 14, each fixed to one end of the base 5. Each pair of slots 14 can engage both ends of the support shaft 151. The support shaft 151 is fixedly connected to a connecting block 15. A limiting frame 9 is fixedly connected to the connecting block 15. The connecting block 15 is fixed to both ends of the limiting frame 9. The two limiting frames 9 can limit the two ends of the axle housing 1.

[0027] Each of the limiting frames 9 is rotatably connected to the limiting rod 12. The other end of the limiting rod 12 is threadedly connected to the set screw 13. The set screw 13 can abut against the positioning block 11. The positioning block 11 is fixed to one side of the support column 10. The support column 10 is fixed on the base 5.

[0028] The limiting frame 9 is made of soft rubber at one end corresponding to the bridge housing 1.

[0029] In this embodiment, the support shaft 151 is inserted into the slot 14 at one end of the base 5 to fix the connecting block 15 and the limiting frame 9. The two limiting frames 9 initially limit the two ends of the bridge housing 1. When the limiting rod 12 is rotated, the limiting rod 12 is threadedly engaged with the set screw 13, and the set screw 13 will move with the rotation of the limiting rod 12. When the set screw 13 abuts against the positioning block 11, the position of the limiting frame 9 is further fixed by tightening the set screw 13, thereby more accurately limiting the position of the end of the bridge housing 1.

[0030] The base 5 is also provided with a lower support member 16, which is installed on the base 5 by bolts and nuts.

[0031] In this embodiment, the lower support member 16 is installed on the base 5 by bolts and nuts, and can be adjusted according to the curvature and height of the bridge housing 1 to provide stable lower support for the bridge housing 1.

[0032] Support plates 8 are fixedly installed on both sides of the upper part of the base 5. There are two sets of support plates 8, and each set is evenly arranged. The fixed end of the linear track 7 is fixedly connected to the support plate 8. The movable end of all the linear tracks 7 is fixedly connected to the moving rod 20. The moving rod 20 is fixedly connected to the abutment block 21. The abutment block 21 can abut against the lower outer side of the bridge shell 1.

[0033] Symmetrical guide blocks 3 are fixedly connected to the upper parts of both sides of the base 5. The guide blocks 3 are passed through by the electric push rod telescopic rod 4. The electric push rod telescopic rod 4 is fixedly connected to the contact head 2. The contact head 2 can abut against the upper part of the outer shell of the bridge housing 1 (the outer shell of the electric push rod is not shown in the figure, only the electric push rod telescopic rod 4 is shown. The outer shell of the electric push rod is fixed to the base 5 by the electric push rod bracket).

[0034] The moving rod 20 is connected to a drive assembly, which includes a motor 19, a rotating rod 18, and a connecting rod 17. The motor 19 is fixed to the upper center of the base 5. The output shaft of the motor 19 is fixedly connected to the center of the rotating rod 18. The two ends of the rotating rod 18 are rotatably connected to one end of the connecting rod 17, and the other end of the connecting rod 17 is rotatably connected to the lower center of the moving rod 20.

[0035] In this embodiment, the motor 19 starts, and its output shaft drives the rotating rod 18 to rotate. The connecting rods 17 at both ends of the rotating rod 18 move with the rotation of the rotating rod 18. The movement of the connecting rods 17 pushes the moving rod 20 to move on the linear track 7, so that the abutment block 21 abuts against the lower outer side of the bridge housing 1.

[0036] The electric push rod extension rod 4 extends and pushes the contact 2 against the upper part of the bridge housing 1, clamping and fixing the bridge housing 1 from multiple directions.

[0037] The method of using this utility model is as follows:

[0038] According to the specifications of the bridge housing 1, adjust the position of the lower support 16 on the base 5, and fix the lower support 16 by tightening the bolts and nuts. Place the bridge housing 1 on the lower support 16 so that both ends of the bridge housing 1 are between the two limit frames 9. After the limit frames 9 are installed, pull the limit rod 12. After the limit rod 12 corresponds to the positioning block 11, rotate the set screw 13 so that the set screw 13 abuts against the positioning block 11 to limit both ends of the bridge housing 1. Start the motor 19. The motor 19 drives the drive component to work, so that the abutment block 21 gradually abuts against the lower outer side of the bridge housing 1. Start the electric push rod so that the electric push rod extension rod 4 extends and the contact 2 abuts against the upper part of the outer shell of the bridge housing 1 to complete the clamping and fixing of the bridge housing 1. Then the bridge housing 1 can be processed.

[0039] After processing is completed, first retract the electric push rod telescopic rod 4, then turn off the motor 19 to make the stop block 21 leave the bridge housing 1, and finally release the limit rod 12, remove the limit frame 9, and then remove the processed bridge housing 1.
