Description

Technical Field

[0001] This utility model relates to the technical field of casting grinding equipment, specifically to a casting edge grinding device. Background Technology

[0002] In the automotive manufacturing industry, there are many types of castings, such as crankcases, valve seats, generator cylinder blocks, crankshafts, camshafts, steering knuckles, etc., which usually need to be made into castings through casting processes.

[0003] In related technologies, after the casting of the steering knuckle is manufactured, a riser is left on the steering knuckle. The riser is punched by a punching machine. However, after punching, burrs will remain on the edge of the riser of the steering knuckle. In order to improve the subsequent assembly quality, a grinding device is needed to grind the burrs on the edge of the riser.

[0004] Most existing steering knuckle riser burr grinding devices use a positioning fixture to place the steering knuckle to be ground, and then the grinding device grinds the riser edge of the steering knuckle. However, after grinding, burr debris usually remains on the positioning fixture. This burr debris falls into the grinding machine through the grinding port on the positioning mold. Usually, the operator places a collection bucket below the corresponding grinding port in the grinding machine to collect the debris. However, because there is a height difference between the grinding port and the collection bucket, some debris will scatter and fall to the ground. Over time, debris will still accumulate on the ground, resulting in poor debris collection. To solve the above problems, a casting edge grinding device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a grinding device for the edge of castings. The debris enters the feeding pipe through the discharge port, enters the protective groove through the sliding hopper, and then enters the feeding nozzle through the protective groove and the discharge square pipe. Finally, the debris falls into the collection box, thereby collecting the debris. When it is necessary to clean the debris in the collection box, the electric push rod on the pushing component drives the sliding plate to move, thereby pushing the collection box installed on the sliding plate to the discharge end of the slide rail. Then the collection box is taken out to process the waste, thereby improving the efficiency of debris collection.

[0006] To solve the above-mentioned technical problems, this utility model provides a grinding device for the edge of castings, including a positioning device set on the grinding machine table, a grinding device set on the upper part of the positioning device, a fixed plate connected to the bottom of the positioning device, a discharge port in the middle of the fixed plate, a sliding hopper below the discharge port, a protective groove at the discharge end of the sliding hopper, a discharge square tube at the bottom of the protective groove, a collection box at the bottom of the discharge square tube, a sliding plate at the bottom of the collection box, a sliding rail slidably set at the bottom of the sliding plate, and a pushing component on one side of the sliding rail.

[0007] The pushing assembly includes a connecting block connected to the sliding plate. The connecting block is used to connect the sliding plate to the telescopic end of the electric push rod. An electric push rod is provided on the side of the connecting block away from the sliding plate. The electric push rod is used to drive the sliding plate to move within the slide rail. A limiting plate is provided on each of the left and right sides of the driving end of the electric push rod. The limiting plate is used to prevent the sliding plate from falling off the driving end of the electric push rod.

[0008] The upper surface of the sliding plate is provided with a placement groove, which is used to fix the collection box and prevent it from falling off when moving. The opening of the placement groove fits tightly with the bottom of the collection box.

[0009] The discharge end of the discharge square tube is equipped with a discharge nozzle, which is used to reduce the diffusion area of ​​grinding waste, so that the grinding waste can fall accurately into the collection box. The discharge end of the discharge nozzle corresponds to the inlet of the collection box.

[0010] A positioning angle iron is provided on one side of the bottom of the feeding nozzle. The positioning angle iron is used to fix the positioning plate to the outer wall of the feeding nozzle. A positioning plate is provided at the bottom of the positioning angle iron. The positioning plate is used to fix the positioning angle iron to the level gauge. A level gauge is provided at the bottom of the positioning plate. The level gauge is used to monitor the material storage in the collection box. When a certain material level is reached, the electric push rod is activated to push the sliding plate out. A baffle is provided on the side of the level gauge near the feeding end of the feeding nozzle. The baffle is used to prevent grinding debris from hitting the level gauge.

[0011] The discharge port is concentric with the grinding port on the positioning device. A feeding pipe is connected to the bottom of the discharge port. The feeding pipe is used to ensure that the waste residue passing through the discharge port can fall accurately into the sliding hopper. The discharge end of the feeding pipe corresponds to the feed end of the sliding hopper.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. Grinding debris enters the discharge pipe through the discharge port, then flows into the protective trough through the sliding hopper, and finally enters the discharge nozzle through the discharge square pipe connected to the protective trough. The debris then falls into the collection box through the discharge nozzle to collect the grinding debris. When it is necessary to clean the debris in the collection box, the electric push rod on the pushing component drives the sliding plate to move, thereby pushing the collection box mounted on the sliding plate to the discharge end of the slide rail. The collection box is then removed to process the waste, thus improving the efficiency of debris collection.

[0014] 2. The placement slot is used to fix the collection box in place, thereby preventing the collection box from falling off when it is moved.

[0015] 3. The level gauge is used to monitor the material level in the collection box. When the material level in the collection box reaches a certain height, the electric push rod is activated to push the sliding plate out, which improves the intelligence of the equipment.

The sliding hopper 200 has an inclined sliding plate inside, which is inclined towards the protective groove 201. The sliding hopper 200 is used for the grinding waste material to slide into the protective groove 201. Inside, the discharge end of the hopper 200 is equipped with a protective groove 201 to prevent grinding waste from splashing. The top of the protective groove 201 is welded and fixed to the bottom of the support frame 106 on the grinding machine base 100, and the bottom of the protective groove 201 is welded and fixed to the top of the support frame 105 on the grinding machine base 100.
