Description

Technical Field

[0001] The utility model relates to the field of chip removal devices for machining centers, in particular to a device which can automatically shut down a chip conveyor when the chip is full. Background Art

[0002] The chip removal device of the machining center is generally started and stopped manually, which is inconvenient to use. Some chip removal devices with automatic start and stop systems are mostly determined according to the machine tool running time or spindle running time, but there are many uncertain factors and the actual effect is not ideal.

[0003] During chip removal, operators must constantly monitor the transfer cart to ensure it is full. Downtime for maintenance reduces machine utilization and impacts production efficiency. Failure to provide timely or neglectful maintenance can lead to chip overflow, polluting the surrounding environment. However, most production sites lack centralized, 24 / 7, non-stop chip removal systems. To address this, we offer a device that automatically shuts down the chip conveyor when it is full, meeting the needs for cost-effective, effective, and highly practical performance. Utility Model Content

[0004] The utility model aims to provide a device which can automatically shut down a chip conveyor when the chip conveyor is full.

[0005] The technical problems solved by the present utility model are:

[0006] (1) In the prior art, the operator needs to always pay attention to whether the waste chips in the transfer vehicle are full during the chip removal process, which easily causes the problem of waste chips overflowing and contamination;

[0007] (2) In the prior art, the transfer vehicle is fixed in one position when the debris is loaded, and the debris is difficult to spread throughout the entire vehicle compartment, resulting in a decrease in loading efficiency.

[0008] The utility model can be realized by the following technical solution: a device for automatically shutting down a chip conveyor when full of chips, comprising a chip conveyor and a transfer vehicle, a carrying platform being provided just below the chip discharge port of the chip conveyor, and the transfer vehicle being placed on top of the carrying platform during loading;

[0009] During the chip removal process, the transfer vehicle oscillates back and forth on top of the carrier platform, so that the chips are flattened inside the transfer vehicle;

[0010] Infrared detection components with adjustable installation height are installed on both side walls of the chip discharge port of the chip conveyor. The infrared detection components detect the chip accumulation height of the transfer vehicle.

[0011] The further technical improvement of the present invention is that a reciprocating screw is installed horizontally in the supporting platform, and a reciprocating nut is connected to the supporting platform in a sliding manner through a thread on the outer side of the reciprocating screw. A roller that can be raised and lowered is provided on the top of the reciprocating nut, and the roller contacts and cooperates with a strip-shaped annular sleeve fixed in the middle position of the bottom of the transfer vehicle to pull the transfer vehicle.

[0012] A further technical improvement of the present invention is that the length of the strip-shaped annular sleeve relative to the moving direction of the roller is greater than the diameter of the roller.

[0013] A further technical improvement of the utility model is that a threaded shaft that can be driven to rotate by a motor is vertically arranged on the reciprocating nut, a threaded sleeve is provided on the outer threaded sleeve of the threaded shaft, a roller is rotatably installed on the top of the threaded sleeve, and the threaded sleeve and the reciprocating nut are slidably matched through splines.

[0014] A further technical improvement of the present invention is that a rotating shaft is rotatably arranged on the carrier and is perpendicular to the reciprocating screw in a horizontal plane, the two are driven by a bevel gear pair, and the rotating shaft is connected to the power end of the chip conveyor through a belt drive.

[0015] A further technical improvement of the present invention is that the infrared detection component includes adjustment slide rails symmetrically fixed on the two outer side walls of the chip discharge port. Each adjustment slide rail is provided with an adjustment slider on one side that can slide up and down, and the adjustment slider can be locked in position at any time by a screw. The two adjustment sliders are respectively penetrated and fixed with an infrared transmitter and an infrared receiver at the same horizontal height near the bottom end.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The utility model detects the debris accumulation height in the transfer vehicle in real time by setting an infrared detection component. When the debris accumulation height blocks the infrared reception, the chip conveyor is automatically shut down to prevent the continued loading of debris from overflowing and polluting the production environment.

[0018] 2. The utility model drives the nut to move back and forth by arranging a reciprocating screw in the bearing platform, and uses the liftable roller and the strip ring sleeve to pull the transfer vehicle to move, thereby changing the landing point of the debris, making it as flat as possible inside the transfer vehicle, and increasing the actual loading capacity; in addition, the length of the strip ring sleeve is greater than the diameter of the roller, which can also make the transfer vehicle move a certain distance by inertia after losing traction to form an impact with the buffer pin, and further vibrate to make the internal debris accumulate evenly, preventing the phenomenon of excessive local accumulation.

[0032] A clearance groove is provided in the middle of the support platform 3 along the extending direction of the reciprocating screw 303, in which a reciprocating nut 306 is slidably installed. The reciprocating nut 306 is sleeved on the outer periphery of the reciprocating screw 303 and is engaged with its thread transmission;

[0033] A small motor is fixed inside the reciprocating nut 306, and a threaded shaft 309 is fixed to the output end of the motor.
