Description

Technical Field

[0001] The invention relates to the technical field of welding tooling for vehicle air compressors, and in particular to a base positioning tooling for intelligent series bulk truck air compressors and a use method thereof. Background Art

[0002] The vehicle air compressor, also known as the air compressor (English: air compressor), is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy and is a compressed air pressure generating device. Bulk vehicle air compressors are used to discharge the powder in the bulk tank out of the bulk tank through air compression. The air compressor base in the existing workshop is manually welded. During the process, it is impossible to ensure that the welded parts of the air compressor base remain stationary. If there is a position shift, the entire base will be scrapped or cut off and re-welded, which greatly reduces production efficiency. At the same time, during the welding process, the welded parts will undergo a certain amount of deformation at the weld due to the lack of external pressure objects, which makes subsequent assembly difficult, welding quality poor, work efficiency low, and employee labor intensity high. Summary of the invention

After rotating to degrees, the horizontal part becomes vertical, the vertical part becomes horizontal, and the lower part of the air compressor base is limited by the pusher;

[0015] B. Then adjust nut 1 to the appropriate position, and then rotate the adjusting rod 1, which rotates through the sleeve and the shaft until the pressure plate is placed flat on the upper part of the air compressor base;

[0016] C. Adjust the second nut to a suitable position, and then rotate the second adjusting rod so that the second adjusting rod is inserted into the inside of the connecting notch. At this time, the second nut and the second wedge block are located above the connecting notch;

[0017] D. Adjust nut 2 downward until wedge block 2 fits with wedge block 1 and the pressure plate is in a horizontal state, then weld the air compressor base. After welding is completed, reverse the operation to separate the adjustment rod 2 and the connecting notch, and remove the air compressor base.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1.

The wedge block 1 and the wedge block 2 are used in combination with the nut 2, the nut 1 and the connecting groove to achieve a more efficient clamping effect, while ensuring that the pressure plate is in a horizontal state after clamping.

[0022] 4. The compression spring provided on the adjusting rod 1 in the present invention can ensure the clamping effect of the device and the leveling effect after the pressure plate presses the air compressor base, and can also prevent the pressure plate from being deformed after a long time due to the height of nut 1 and nut 2 not being completely consistent and affecting the welding quality, thereby indirectly improving the reliability of the device.

[0023] 5. In the present invention, a mounting hole is provided on the limit plate and a sub-plate with an L-shaped structure is rotatably connected inside the mounting hole.

DETAILED DESCRIPTION

[0029] 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.

[0030] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] Embodiment 1:

[0032] like Figures 1 to 3As shown, the intelligent series of bulk truck air compressor base positioning tooling includes a working platform 1, on which a limit plate 2, a clamping unit and a locking unit are installed. The clamping unit includes a fixed seat 3, a rotating shaft 4 and a clamping structure. The fixed seat 3 is fixedly connected to the left side of the upper surface of the working platform 1, and the rotating shaft 4 is installed on the fixed seat 3. The rotating shaft 4 is provided with a clamping structure. The locking unit includes a fixed seat 2 5 and a locking structure. The fixed seat 2 5 is fixedly connected to the right side of the upper surface of the working platform 1, and the fixed seat 2 5 is rotatably connected with the locking structure. After the air compressor base is clamped by the clamping structure, it is adapted to be connected and locked with the locking structure. The clamping structure is rotated to the top of the air compressor base through the rotating shaft 4, and then the clamping structure is locked by the locking structure to ensure the clamping effect to prevent deviation during welding, thereby ensuring the welding quality of the air compressor base, and effectively solving the technical problems that the current workshop personnel cannot reduce the welding deformation during welding when operating the welding of the air compressor base, resulting in great difficulty in subsequent assembly, poor welding quality, low work efficiency, and high labor intensity for employees.

[0033] In the further preferred solution of the present embodiment, the clamping structure comprises a sleeve 6, an adjusting rod 7, a nut 8 and a pressing plate 9, the sleeve 6 is rotatably connected to the rotating shaft 4, one end of the adjusting rod 7 is fixedly connected to the sleeve 6, and the other end is matched and connected with a nut 8, the pressing plate 9 is movably arranged on the outside of the adjusting rod 7 and located between the nut 8 and the sleeve 6, and a connecting notch 10 is provided at one end of the pressing plate 9 away from the adjusting rod 7. The sleeve 6 and the pressing plate 9 are driven to rotate together toward the upper side of the air compressor base by rotating the adjusting rod 7, and the nut 8 limits the clamping height of the pressing plate 9.

[0034] In a further preferred solution of this embodiment, the locking structure includes an adjusting rod 11 and a nut 12, wherein the adjusting rod 11 is rotatably connected to the fixing seat 5, and the nut 12 is connected to the outer side of the adjusting rod 11 through thread matching and is located on a side away from the fixing seat 5. The adjusting rod 11 is rotated so that the adjusting rod 11 is inserted into the connecting notch 10, and then the nut 14 is adjusted so that the pressing plate 10 is pressed, thereby achieving the effect of pressing the entire air compressor base.

[0035] In a further preferred embodiment of the present invention, a positioning groove 16 adapted to the second nut 12 is provided on the pressure plate 9 at the connection notch 10. The positioning groove 16 is used to limit the position of the second nut 12 to prevent the connection notch 10 from separating from the second adjustment rod 11.

[0036] In a further preferred solution in this embodiment, a mounting opening is opened on the limit plate 2, and a sub-plate 17 is rotatably connected inside the mounting opening. The sub-plate 17 is an L-shaped structure. When the air compressor base is installed on the working platform 1, the sub-plate 17 is rotated 90 degrees to limit the lower part of the air compressor base.

[0037] In the further preferred solution of the present embodiment, the sub-plate 17 includes a horizontal part and a vertical part connected in an integral manner, the horizontal part is rotatably connected to the limit plate 2, a blind hole is provided on the horizontal part, a pusher 18 is provided inside the blind hole, the pusher 18 is arranged inside the blind hole by a spring, and a part of the pusher 18 extends to the outside of the blind hole. The positioning effect of the lower part of the air compressor base is controlled by the action of the horizontal part and the vertical part of the sub-plate 17 on the lower part of the air compressor base in different states, so as to further improve the positioning effect and welding quality of the device. At the same time, when the vertical part is in a horizontal state, the lower part of the air compressor base cannot be automatically separated by the action of the pusher 18 and the spring, and an external force needs to be applied to separate the sub-plate 17 from the air compressor base, thereby ensuring the positioning effect of the lower part of the air compressor base.

The combination of the wedge block 13 and the wedge block 14 with the nut 12, the nut 18 and the connection notch 10 can achieve a more efficient clamping effect, and at the same time ensure that the pressure plate is in a horizontal state after being clamped.

[0040] In the present embodiment, a further preferred solution is that a compression spring 15 is mounted on the adjusting rod 1 7, and the compression spring 15 is arranged between the pressure plate 9 and the nut 1 8. This can ensure the pressing effect of the device and the leveling effect after the pressure plate presses the air compressor base, and can also prevent the pressure plate 9 from being deformed after a long time due to the height of the nut 1 8 and the nut 2 14 not being completely consistent and affecting the welding quality, thereby indirectly improving the reliability of the device.

After rotating to 90 degrees, the horizontal part becomes vertical, the vertical part becomes horizontal, and the lower part of the air compressor base is limited by the pusher 18;

[0044] B. Then adjust the nut 8 to a suitable position, and then rotate the adjusting rod 7, which rotates with the rotating shaft 4 through the sleeve 6 until the pressure plate 9 is placed flat on the upper part of the air compressor base;

[0045] C. Adjust the nut 12 to a suitable position, and then rotate the adjusting rod 11 so that the adjusting rod 11 is inserted into the connecting notch 10. At this time, the nut 12 and the wedge block 14 are located above the connecting notch 10.

[0046] D. Adjust nut 2 12 downward until wedge block 2 14 fits with wedge block 1 13 and pressure plate 9 is in a horizontal state, then weld the air compressor base.
