Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub casting, in particular to a riser removal device for a cast-spun aluminum alloy wheel hub. Background Art

[0002] Aluminum alloy casting wheels are divided into low-pressure casting, gravity casting, and casting spinning. The casting spinning process is a more advanced process than other casting processes. The rim of the wheel is spun out using a strong spinning machine, making the rim thinner, denser, and better in performance. Its performance is similar to that of a forged wheel.

[0003] However, when producing cast-spinning hubs, a riser left by casting will be left at the center hole of the hub. The riser will affect the pressure of the upper die on the casting during spinning, and will also affect the positioning during milling.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1-6As shown, the utility model provides a technical solution:

[0033] A cast-spun aluminum alloy wheel hub riser removal device, comprising:

[0034] A support frame 1, on which a logistics line 2 is arranged, and the logistics line 2 is used to transport a wheel hub 17; a drilling unit is arranged on the support frame 1 below the logistics line 2, and the drilling unit includes a drill bit 3, and the drill bit 3 can move toward the direction of the logistics line 2, and is used to drill and mill the riser 18 in the center of the wheel hub 17, and the drill bit 3 can also be replaced with a drilling and milling cutter; a clamping unit includes a left clamping fixture 4 and a right clamping fixture 5, which are respectively arranged on both sides of the transportation direction of the logistics line 2, and the left clamping fixture 4 and the right clamping fixture 5 can move relatively close to or away from each other at the same time, and are used to center, clamp or loosen the wheel hub on the logistics line 2; a gantry frame 6 is arranged above the support frame 1, and a pressing unit is arranged on the gantry frame 6, and the pressing unit includes a pressing block 7, and the pressing block 7 can move toward the direction of the logistics line 2, and is used to press the wheel hub 17 onto the logistics line 2.

[0035] In this embodiment, the logistics line 2 is configured as a roller logistics line. The structure and application of the roller logistics line belong to the conventional settings of transportation in this field. It is mainly used to drive the hub 17 to move. Its specific principle does not need to be elaborated. The use of conventional roller logistics lines reduces the cost of the device and has good economy.

[0036] In this embodiment, a window is opened on the logistics line 2 at a position directly opposite to the drill bit 3. On the roller logistics line, the roller directly above the drill bit 3 that obstructs the movement of the drill bit 3 is removed to form a window. Alternatively, without affecting the movement of the wheel hub 17, a roller logistics line with a large spacing between adjacent rollers is selected, and the large gap between two adjacent rollers is used as a window to prevent the logistics line 2 from affecting the movement of the drill bit 3, thereby improving the practicability of the device.

[0037] In this embodiment, the drilling unit also includes a telescopic power part 8, which is a telescopic cylinder. The telescopic power part 8 is arranged on the support frame 1 below the logistics line 2, and the telescopic direction of the output end of the telescopic power part 8 is toward the logistics line 2. A mounting seat 9 is arranged on the output end of the telescopic power part 8, and a rotating power part 10 is arranged on the mounting seat 9. The rotating power part 10 is an electric motor, and a drill bit 3 or a drill milling cutter is arranged at the output end of the rotating power part 10 to achieve the removal of the riser, thereby improving the stability of the device.

[0038] In this embodiment, the clamping unit also includes a left clamping bracket 11 and a right clamping bracket 12, and the left clamping bracket 11 and the right clamping bracket 12 are respectively arranged on both sides of the conveying direction of the logistics line 2. A left clamping power member 13 is arranged on the left clamping bracket 11, and a right clamping power member 14 is arranged on the right clamping bracket 12. The left clamping power member 13 and the right clamping power member 14 are both electric push rods. The output ends of the left clamping power member 13 and the right clamping power member 14 are relatively arranged, and the axes of the output ends of the left clamping power member 13 and the right clamping power member 14 are in the same straight line. A left clamping fixture 4 is arranged at the output end of the left clamping power member 13, and a right clamping fixture 5 is arranged at the output end of the right clamping power member 14, so as to perform left and right centering positioning of the hub 17 on the logistics line 2, so that the position of the hub 17 is determined, and the riser below the center of the hub 17 is directly opposite to the drill bit 3, thereby improving the accuracy of device processing.

[0039] In this embodiment, the surfaces of the left clamping fixture 4 and the right clamping fixture 5 that contact the wheel hub are set to be arc surfaces that adapt to the curvature of the wheel hub edge, so as to better clamp the wheel hub 17 so that the freedom of the wheel hub 17 in the front, back, left and right directions can be restricted, thereby improving the stability of the device processing.

[0040] In this embodiment, the clamping unit also includes a clamping power member 15, which is an electric push rod. The fixed end of the clamping power member 15 is arranged on the gantry 6, and the output end of the clamping power member 15 is facing the drilling unit and can move. A clamping block 7 is arranged at the output end of the clamping power member 15 to drive the clamping block 7 to move toward the drilling unit, so as to clamp the hub 17 on the logistics line 2, prevent the drill bit 3 from moving up and down when drilling the riser 18, and improve the safety of the device.

[0041] In this embodiment, the axis of the output end of the rotating power member 10 is in the same straight line as the axis of the output end of the clamping power member 15, and the axes of the output ends of the rotating power member 10, the clamping power member 15, the left clamping power member 13 and the right clamping power member 14 are all located in the same plane. The axis of the output end of the rotating power member 10 is located at the midpoint of the line connecting the left clamping power member 13 and the right clamping power member 14, thereby avoiding quality problems caused by inaccurate positioning of the drill bit 3 before drilling the riser 18, thereby improving the practicability of the device.

[0042] In this embodiment, a groove 71 is provided at the position of the clamping block 7 corresponding to the riser, and the position where the clamping block 7 contacts the upper part of the hub 17 is set to correspond to the surface shape of the hub 17 to increase the contact area with the hub 17 and improve stability.

[0043] In another embodiment, the left clamping fixture 4, the right clamping fixture 5, the clamping block 7 and the drill bit 3 are all configured to be detachable. By replacing them to adapt to the hub 17 with different surface shapes, different sizes and different riser diameters, the application range of the device is increased and the practicality of the device is improved.

[0044] In this embodiment, a cooling unit is also included, which includes a cutting fluid nozzle 16, which is arranged on the support frame 1. The cutting fluid nozzle 16 is connected to the cutting fluid supply device, and the nozzle is directed toward the drill bit 3. It is used to spray cutting fluid to the drill bit 3 when milling the riser 18 to reduce the temperature of the drill bit 3 and improve efficiency. Preferably, the nozzle direction of the cutting fluid nozzle 16 can be adjusted to avoid affecting the movement of the wheel hub, thereby improving the safety of the device.

[0045] In this embodiment, a control component is also included, which connects the logistics line 2, the telescopic power member 8, the rotating power member 10, the left clamping power member 13, the right clamping power member 14 and the pressing power member 15 to efficiently control the overall operation of the device, reduce labor intensity and improve efficiency.

[0046] In another embodiment, an induction switch is provided on one side of the logistics line 2, and the induction switch is connected to the control component. When the hub 17 passes through the induction switch, the control component controls the logistics line 2 to pause conveying the hub 17, and at this time the hub 17 is located exactly between the left clamping fixture 4 and the right clamping fixture 5, so as to realize automatic positioning of the device and improve the practicability of the device.

[0047] Working principle: First, after the wheel hub comes out of the casting machine, it is transported to the position of the clamping unit through the logistics line 2. The logistics line 2 stops conveying, and the left clamping fixture 4 and the right clamping fixture 5 move toward each other to clamp the two sides of the wheel hub. Since the surfaces of the left clamping fixture 4 and the right clamping fixture 5 in contact with the wheel hub are set to be arc surfaces that adapt to the arc of the edge of the wheel hub, the freedom of the wheel hub to move forward, backward, left and right on the plane is restricted, and the position of the wheel hub is limited. At this time, the position of the center riser of the wheel hub is exactly the position of the drill bit 3 below it; start the clamping power piece 15, Drive the clamping block 7 to move toward the wheel hub and press the wheel hub onto the logistics line 2 to prevent the wheel hub from moving during drilling and milling by the drill bit 3, thereby improving stability; start the rotating power part 10 to drive the drill bit 3 to rotate, and at the same time start the telescopic power part 8 to move the drill bit 3 toward the riser direction, and the cutting fluid nozzle 16 sprays cutting fluid on the drill bit 3 to cool the drill bit 3. After the drill bit 3 cuts off the riser, it rotates back, the clamping block 7 rises, and the left clamping fixture 4 and the right clamping fixture 5 move in opposite directions to release the wheel hub. The logistics line 2 continues to transport and sends the hub after the riser is removed to the next operating surface.
