Description

Technical Field

[0001] This utility model relates to a device for removing sprue marks, and more specifically, to a device for removing sprue marks in wheel hub casting. Background Technology

[0002] Die casting is a type of pressure casting of parts. It is a process in which a pressure casting machine equipped with a casting mold is used to pour molten metal such as copper, zinc, aluminum or aluminum alloy into the feed port of the casting machine, and then the casting machine casts parts of the shape and size limited by the mold.

[0003] After casting, the sprue needs to be removed and the burrs need to be polished to achieve a relatively smooth surface. In the current traditional process, the sprue and burrs are usually manually punched and polished. This operation method involves high labor intensity and is dangerous for workers, which can easily cause hand injuries. It also requires a high level of technical skill and attention from the workers, which can easily lead to over-polishing and scrapping of the product. Utility Model Content

[0020] See Figure 1-4 As shown, the present invention provides a wheel hub casting sprue removal device, which includes a machine platform 1 set between two roller conveyors. A lifting assembly 2 is provided on the roller conveyor on the feed end side of the machine platform 1, and a vibration sprue removal assembly 3 is provided on the lifting assembly 2.

[0021] The machine base 1 is equipped with a rotating platform 4. A unidirectional pushing assembly 5 is located above the roller conveyor on the side of the machine base 1 facing the material inlet direction. A positioning and clamping assembly 6 that mates with the wheel hub is located on the side of the machine base 1 perpendicular to the conveying direction of the roller conveyor. A movable grinding wheel assembly 7 is located on the side of the machine base 1 opposite to the positioning and clamping assembly 6. A positioning cylinder 8 that mates with the wheel hub is located above the rotating platform 4. The rotating platforms and the grinding wheel assembly are arranged in opposite directions of rotation to ensure that the grinding wheel assembly can effectively grind the sprue.

[0022] The hub is deburred by a vibratory deburring assembly. After being conveyed to a rotating platform, the hub is clamped by a grinding wheel assembly and a positioning clamping assembly to grind the sprue. The entire grinding process is automated, which effectively reduces the labor intensity of workers, improves safety, and increases the removal efficiency. In addition, the equipment has high grinding precision and is controllable, making it less likely to cause over-grinding and scrapping of products.

[0023] In this embodiment, the vibratory deburring assembly 3 includes a mounting bracket 3a hinged to the lifting assembly 2. A deburring plate 3c with an inverted trapezoidal cross-section is suspended below the mounting bracket 3a by several chains 3b. An oscillating motor 3d is mounted on the deburring plate 3c. Because the deburring plate is inverted trapezoidal, when the oscillating motor drives the deburring plate to vibrate, its chamfered ends rub against the upper surface of the hub, scraping away the burrs.

[0024] A positioning head 3e, which mates with the inner hole of the wheel hub, is located at the bottom of the deburring plate 3c. Several arc-shaped protrusions 3f are evenly distributed circumferentially on the outer wall of the positioning head 3e. This structure facilitates the insertion of the positioning head into the inner hole of the wheel hub. When the deburring plate vibrates, the arc-shaped protrusions rub against the inner wall of the wheel hub's inner hole, scraping off the burrs on the inner hole. These scrapes then fall through the gaps between the arc-shaped protrusions and into the lower part of the wheel hub, preventing debris from remaining between the positioning head and the inner wall of the wheel hub and affecting the subsequent deburring effect.

[0025] In this embodiment, the unidirectional pushing assembly 5 includes a guide rail 5a disposed above the roller conveyor, a first horizontal cylinder 5b disposed on the guide rail 5a, and a sliding seat 5c cooperating with the guide rail 5a connected to the piston rod of the first horizontal cylinder 5b.

[0026] The sliding seat 5c is hinged at its front end to a one-way push rod 5d that rotates upwards. Initially, the free end of the one-way push rod 5d is vertically downwards. The free end of the one-way push rod 5d, near the material feeding direction, has an inclined pushing surface 5e that mates with the upper end of the hub. When the one-way push rod 5d rotates to a horizontal position, the inclined pushing surface 5e is in contact with the upper end of the hub. After the inclined pushing surface is in contact with the upper end of the hub, the piston rod of the first horizontal cylinder extends to push the hub onto the rotating platform. Then, the piston rod retracts, causing the one-way push rod to leave the upper end of the hub and return to a vertical position. After grinding is completed, the piston rod of the first horizontal cylinder extends again, and the one-way push rod pushes the hub onto the roller conveyor on the other side.

[0027] In this embodiment, the positioning and clamping assembly 6 includes a second horizontal cylinder 6a hinged to a machine base 1 on a side perpendicular to the conveying direction of the roller conveyor. An arc-shaped push plate 6b is connected to the piston rod of the second horizontal cylinder 6a. A sliding wheel 6c is provided at the bottom of the arc-shaped push plate 6b, and a guide groove 6d that cooperates with the sliding wheel 6c is provided on the machine base 1. Two guide rollers 6e are provided at both ends of the arc-shaped push plate 6b. The second horizontal cylinder is hinged and can swing horizontally to prevent the horizontal thrust generated when the hub rotates from being transmitted to the second horizontal cylinder and causing damage.

[0028] By setting guide rollers to work with the hub, the hub can be positioned while avoiding friction that would cause wear on the hub surface during rotation.

[0029] In this embodiment, preferably, the grinding wheel assembly 7 includes a mounting base 7a hinged to the machine base 1, a drive motor 7b mounted on the mounting base 7a, and a grinding wheel 7c connected to the drive motor 7b; a connecting rod 7d is provided at the free end of the mounting base 7a, and a third horizontal cylinder 7e is hinged to the machine base 1, the piston rod of the third horizontal cylinder 7e being hinged to the connecting rod 7d. Initially, the grinding wheel is located outside the rotating platform. When the wheel hub is transported to the rotating platform, the piston rod of the third horizontal cylinder retracts, clamping the grinding wheel with the opposing positioning and clamping assembly to position the wheel hub and perform grinding.

[0030] During operation, the wheel hub is conveyed to the lower part of the lifting assembly via a roller conveyor. The lifting assembly descends to make the deburring plate fit against the upper end of the wheel hub and the positioning head is located in the inner hole of the wheel hub. The vibrating motor causes the deburring plate to vibrate and clean the deburring on the upper surface of the wheel hub.

[0031] After removing the burrs from the upper end face, the hub continues to be conveyed along the roller conveyor to one side of the machine platform. When the one-way push rod is lifted to a horizontal state, the roller conveyor stops working. The first horizontal cylinder pushes the hub onto the rotating platform and the front end of the hub contacts the positioning block. The piston rod of the positioning cylinder descends and enters the inner hole of the hub for positioning. After positioning is completed, the first horizontal cylinder retracts.

[0032] Then the piston rod of the second horizontal cylinder extends, while the piston rod of the third horizontal cylinder retracts, causing the guide roller and the grinding wheel to contact the outer surface of the hub. The rotating platform and the grinding wheel then begin to rotate to grind the hub.

[0033] After grinding is completed, the piston rods of the second and third horizontal cylinders return to their initial positions, and the piston rod of the first horizontal cylinder extends to drive the one-way push rod to push the hub onto the roller conveyor on the other side for transport.

[0034] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
