Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing technology, specifically an adjustable annular blower for wheel hub processing. Background Technology

[0002] During the pre-treatment cleaning process, residual water remains in the bolt holes of the wheel hubs. This water often cannot be completely dried when passing through the drying oven, thus affecting the painting quality. Existing equipment requires compressed air connected to a bamboo tube to blow water into the bolt holes before the product enters the drying oven, which can solve the problem of residual water in the bolt holes to some extent.

[0003] However, existing equipment cannot adjust the blowing area during actual use. As the variety of products increases, the number and depth of bolt holes on many products also increase. When cleaning products of different sizes simultaneously, there will be instances of missed blowing. To reduce this problem, two more identical blowing devices are added. Running all three blowing devices simultaneously results in a significant waste of compressed air and energy. Therefore, a new type of blowing device is needed to solve the current problem. In view of this, we propose an adjustable annular blowing device for wheel hub processing. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable annular blower for wheel hub processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable annular blower for wheel hub processing, comprising a duct frame, a rotating shell fixedly connected to the outer wall of the duct frame, an annular tube provided on the outer wall of the rotating shell, a blower nozzle fixedly connected to one end of the annular tube, a main air duct fixedly connected to the other end of the annular tube, a circular tube fixedly connected to the end of the main air duct away from the annular tube, a motor fixedly connected to the outer wall of the rotating shell, the output end of the motor penetrating the rotating shell, and an adjustment assembly provided inside the rotating shell, the adjustment assembly comprising:

[0006] A housing is fixedly connected to the output end of the motor. A telescopic rod is fixedly connected to the inner wall of the housing. A lower hinge plate is hinged to the output end of the telescopic rod. A lower clamping plate is hinged to the end of the lower hinge plate away from the telescopic rod.

[0007] The upper hinge plate is hinged to the side of the telescopic rod output end away from the upper hinge plate. The upper hinge plate is hinged to an upper clamping plate at the end away from the telescopic rod. The annular tube is arranged between the upper clamping plate and the lower clamping plate. Limiting blocks are fixedly connected to the outer walls of both the upper and lower clamping plates. The outer wall of the sleeve is provided with a limiting groove that matches the limiting block.

[0008] Preferably, the blower nozzle is provided with an air control assembly, which includes a push rod fixedly connected to the outer wall of the blower nozzle. A collar is fixedly connected to the output end of the push rod. A pull plate is hinged to the outer wall of the collar. A rotating plate is hinged to the end of the pull plate away from the collar. The rotating plate is rotatably connected to the outer wall of the blower nozzle. A torsion spring is provided at the connection between the rotating plate and the blower nozzle. A membrane is fixedly connected to the outer wall of the rotating plate. The blowing area of ​​the blower nozzle can be adjusted by controlling the opening angle of the pull plate.

[0009] Preferably, the blower nozzle consists of an air inlet pipe and a blower pipe. The collar is sleeved on the outer wall of the blower pipe and is slidably connected to the outer wall of the blower pipe, so that when the push rod is extended, it can push the collar to slide on the outer wall of the blower pipe, thereby causing the collar to drive the rotating plate to rotate through the pull plate, and thus the rotation angle of the rotating plate can be adjusted, and the blowing area of ​​the blower nozzle can be adjusted.

[0010] Preferably, the rotating plate is rotatably connected to the outer wall of the air outlet, one end of the torsion spring is fixedly connected to the outer wall of the air pipe, and the other end of the torsion spring is fixedly connected to the outer wall of the rotating plate. The torsion spring enables the rotating plate to always rotate in the direction of the air pipe, so that the rotating plate can remain fixed after being driven and rotated by the collar, and the opening angle of the air control assembly can be fixed.

[0011] Preferably, the inner wall of the casing has two sets of rotating grooves. The upper hinge plate and the lower hinge plate are rotatably connected to the inner wall of one set of rotating grooves, and the limiting block is slidably connected to the inner wall of the limiting groove. When the telescopic rod extends or retracts, the upper hinge plate and the lower hinge plate rotate in the rotating groove, so that the upper clamping plate and the lower clamping plate move more smoothly on the casing through the cooperation of the limiting groove and the limiting block.

[0012] Preferably, the output end of the telescopic rod is fixedly connected to a fixed plate, the upper hinge plate is hinged to the outer wall of the fixed plate, and the upper hinge plate and the lower hinge plate have the same length, so that when the telescopic rod is extended or retracted, the upper hinge plate and the lower hinge plate rotate at the same angle, thereby keeping the distance between the upper clamping plate and the lower clamping plate consistent.

[0013] Preferably, the distance between the upper clamping plate and the lower clamping plate is consistent with the diameter of the annular tube. The upper clamping plate is attached to the upper outer wall of the annular tube, and the lower clamping plate is attached to the lower outer wall of the annular tube. This allows the upper and lower clamping plates to better drive the annular tube to expand its deformation diameter when moving towards the outer wall of the rotating shell, thereby changing the position of the blower nozzle to adapt to the threaded hole on the outer side of the hub. When the upper and lower clamping plates move towards the axis of the rotating shell, they can better drive the annular tube to reduce its deformation diameter.

[0014] Compared with the prior art, this utility model provides an adjustable annular blower for wheel hub processing, which has the following advantages:

[0015] 1. This adjustable annular blower for wheel hub processing uses a telescopic rod to extend and retract, and the upper and lower hinge plates to rotate. The upper and lower clamping plates change the diameter of the annular tube and the position of the blower nozzle through the cooperation of the limiting groove and the limiting block. At the same time, the motor drives the rotating shell to rotate the blower nozzle, so that the blower nozzle can blow water to the threaded holes in different positions. The annular blower replaces the original single-pipe blower and solves the problem of insufficient blower coverage.

[0016] 2. The adjustable ring blower for wheel hub processing uses a push rod to extend and retract, causing the collar to slide on the outer wall of the blower pipe. The collar drives the rotating plate to rotate via a pull plate. The torsion spring fixes the opening angle of the rotating plate after rotation, allowing the area of ​​the blower nozzle to be adjusted, thus enabling the equipment to better blow water into the screw holes.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: an adjustable annular blower for wheel hub processing, including a duct frame 1, a rotating shell 2 fixedly connected to the outer wall of the duct frame 1, an annular pipe 3 provided on the outer wall of the rotating shell 2, a blower nozzle 4 fixedly connected to one end of the annular pipe 3, a main air pipe 5 fixedly connected to the other end of the annular pipe 3, a round pipe 6 fixedly connected to the end of the main air pipe 5 away from the annular pipe 3, a motor 7 fixedly connected to the outer wall of the rotating shell 2, the output end of the motor 7 penetrating through the rotating shell 2, and an adjustment component 8 provided inside the rotating shell 2. The adjustment component 8 includes a housing 81, a telescopic rod 82, a lower hinge plate 83, a lower clamping plate 84, an upper hinge plate 85, an upper clamping plate 86, a limiting block 87, and a limiting groove 88.

[0023] In one embodiment of this utility model, the housing 81 is fixedly connected to the output end of the motor 7, and the inner wall of the housing 81 is fixedly connected to the telescopic rod 82. The output end of the telescopic rod 82 is hinged to the lower hinge plate 83, and the end of the lower hinge plate 83 away from the telescopic rod 82 is hinged to the lower clamping plate 84.

[0024] In one embodiment of this utility model, the upper hinge plate 85 is hinged to the side of the output end of the telescopic rod 82 away from the upper hinge plate 85, and the upper clamping plate 86 is hinged to the end of the upper hinge plate 85 away from the telescopic rod 82. The annular tube 3 is arranged between the upper clamping plate 86 and the lower clamping plate 84. Limiting blocks 87 are fixedly connected to the outer walls of the upper clamping plate 86 and the lower clamping plate 84. The outer wall of the sleeve 81 is provided with a limiting groove 88 that matches the limiting block 87.

[0025] In one embodiment of this utility model, the annular tube 3 is connected in a bamboo-joint manner, and can be increased or decreased. The diameter of the annular tube 3 is determined according to the size of the wheel hub flange. Among all currently produced products, the diameter is designed to be 260mm based on the largest flange size, which can cover the air blowing area of ​​all product bolt holes.

[0026] In addition, an air control assembly 9 is provided on the outside of the blower nozzle 4. The air control assembly 9 includes a push rod 91, which is fixedly connected to the outer wall of the blower nozzle 4. A collar 92 is fixedly connected to the output end of the push rod 91. A pull plate 93 is hinged to the outer wall of the collar 92. A rotating plate 94 is hinged to the end of the pull plate 93 away from the collar 92. The rotating plate 94 is rotatably connected to the outer wall of the blower nozzle 4. A torsion spring 95 is provided at the connection between the rotating plate 94 and the blower nozzle 4. A membrane 96 is fixedly connected to the outer wall of the rotating plate 94. The blowing area of ​​the blower nozzle 4 can be adjusted by controlling the opening angle of the pull plate 93, so that the blower nozzle 4 can blow water to threaded holes of different sizes.

[0027] In an embodiment of this utility model, the blower nozzle 4 is composed of an air inlet pipe and a blower pipe. A collar 92 is sleeved on the outer wall of the blower pipe. The collar 92 is slidably connected to the outer wall of the blower pipe, so that when the push rod 91 extends, it can push the collar 92 to slide on the outer wall of the blower pipe. This allows the collar 92 to drive the rotating plate 94 to rotate through the pull plate 93, thereby allowing the rotation angle of the rotating plate 94 to be adjusted. This allows the area of ​​air blown by the blower nozzle 4 to be adjusted, enabling the device to better blow water into the screw hole.

[0028] In this embodiment of the utility model, the rotating plate 94 is rotatably connected to the outer wall of the air outlet, one end of the torsion spring 95 is fixedly connected to the outer wall of the air pipe, and the other end of the torsion spring 95 is fixedly connected to the outer wall of the rotating plate 94. The torsion spring 95 enables the rotating plate 94 to always rotate in the direction of the air pipe, so that the rotating plate 94 can remain fixed after being driven and rotated by the collar 92, so that the opening angle of the air control component 9 can be fixed, thereby enabling the air nozzle 4 to stably blow water to screw holes of different sizes.

[0029] In an embodiment of this utility model, the inner wall of the housing 81 is provided with two sets of rotating grooves. The upper hinge plate 85 and the lower hinge plate 83 are rotatably connected to the inner wall of one set of rotating grooves respectively. The limiting block 87 is slidably connected to the inner wall of the limiting groove 88. When the telescopic rod 82 extends or retracts, the upper hinge plate 85 and the lower hinge plate 83 rotate in the rotating grooves. This allows the upper clamping plate 86 and the lower clamping plate 84 to move more smoothly on the housing 81 through the cooperation of the limiting groove 88 and the limiting block 87, thereby driving the annular tube 3 to deform.

[0030] In this embodiment of the utility model, a fixed plate is fixedly connected to the output end of the telescopic rod 82, and the upper hinge plate 85 is hinged to the outer wall of the fixed plate. The upper hinge plate 85 and the lower hinge plate 83 have the same length, so that when the telescopic rod 82 is extended or retracted, the upper hinge plate 85 and the lower hinge plate 83 rotate at the same angle, thereby keeping the distance between the upper clamping plate 86 and the lower clamping plate 84 consistent, so that the upper clamping plate 86 and the lower clamping plate 84 can better change the shape of the annular tube 3.

[0031] In this embodiment of the utility model, the distance between the upper clamping plate 86 and the lower clamping plate 84 is consistent with the diameter of the annular tube 3. The upper clamping plate 86 is attached to the upper outer wall of the annular tube 3, and the lower clamping plate 84 is attached to the lower outer wall of the annular tube 3. When the upper clamping plate 86 and the lower clamping plate 84 move toward the outer wall of the rotating shell 2, they can better drive the annular tube 3 to expand its deformation diameter, thereby changing the position of the blower nozzle 4 to adapt to the threaded hole on the outer side of the hub. When the upper clamping plate 86 and the lower clamping plate 84 move toward the axis of the rotating shell 2, they can better drive the annular tube 3 to reduce its deformation diameter, thereby changing the position of the blower nozzle 4 to adapt to the threaded hole on the inner side of the hub.

[0032] In this invention, during use, an air inlet is provided on the circular tube 6, which is connected to compressed air to provide an air source. The air is then delivered through the main air pipe 5 to the annular pipe 3 and then to the blower nozzle 4. At this time, the motor 7 causes the rotating shell 2 to drive the blower nozzle 4 to rotate, so that the blower nozzle 4 can blow water onto the threaded holes at different positions. When water needs to be blown onto threaded holes with different arrangements, the telescopic rod 82 extends and retracts, and the upper hinge plate 85 and the lower hinge plate 83 rotate in the rotating groove. This allows the upper clamping plate 86 and the lower clamping plate 84 to cooperate more smoothly in the housing 8 through the cooperation of the limiting groove 88 and the limiting block 87. 1. When the upper clamping plate 86 and the lower clamping plate 84 move towards the outer wall of the rotating shell 2, they can better drive the annular tube 3 to expand its deformation diameter, thereby changing the position of the blower nozzle 4 to adapt to the threaded hole near the outer side of the hub. When the upper clamping plate 86 and the lower clamping plate 84 move towards the axis of the rotating shell 2, they can better drive the annular tube 3 to reduce its deformation diameter, thereby changing the position of the blower nozzle 4 to adapt to the threaded hole near the inner side of the hub. This allows the blower nozzle 4 to blow water onto threaded holes with different arrangements. At this time, the push rod 91 can be extended and retracted to make the collar 92 slide on the outer wall of the blower tube. The collar 92 drives the rotating plate 94 to rotate through the pull plate 93. The torsion spring 95 can make the rotating plate 94 always rotate towards the direction of the blower tube, thereby fixing the opening angle of the air control component 9 after the rotating plate 94 rotates. This allows the rotation angle of the rotating plate 94 to be adjusted, and the blowing area of ​​the blower nozzle 4 to be adjusted, so that the equipment can better blow water onto the threaded holes.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
