Automatic grinding machine for workpiece edges

Abstract

The invention discloses an automatic grinding machine for workpiece edges. The automatic grinding machine comprises a machine case, a machine case cover, a distribution box, a control panel, a power line, a storage battery, a rack, a transverse sliding mechanism, a first motor, a vertical sliding mechanism, a second motor, a machine head, a third motor, a grinding tool, an infrared sensor, a single chip microcomputer, a circuit breaker, an alarm, a waste chipping collection device, a push mechanism, an angle adjustment mechanism and a clamping device; the machine case cover is welded to the periphery of the outer side of the top of the machine case, a workpiece can be adjusted to be at the appropriate angle after being clamped and fixed, rotation is firstly carried out to release a lockingbolt, then an adjusting plate is rotated to drive the clamping device to conduct left-and-right angle adjustment, the angle of the workpiece can be subjected to left-and-right adjustment, a pointer points to the number of degrees of a scaleplate, the workpiece adjusting angle can be quickly understood, and therefore the problems that after the workpiece is clamped and fixed, the left and right angles cannot be changed, the flexibility is insufficient, and the work efficiency is low are solved, and the flexibility and work efficiency are increased.

Description

technical field [0001] The invention relates to the related field of grinding machines, in particular to an automatic grinding machine for workpiece edges. Background technique [0002] At present, the shapes of wood products are various, especially the workpieces with curved surfaces are difficult to process, and the processing efficiency is relatively low. For the processing of such wood products, grinding machines are mostly used to grind the edges of the workpieces. The subsequent processing of wood products is more convenient and the quality is better. [0003] After searching, it is found that the invention of patent No. CN201420053959.7 discloses a grinding machine for grinding the metal surface of a workpiece, including: at least one grinding assembly; at least one grinding table, the grinding table has at least one a conveyor belt for conveying the workpiece through the grinding machine; and a housing in which the grinding assembly is disposed. [0004] After sear...

Problems solved by technology

[0012] The present invention provides an automatic grinding machine for the edge of a workpiece through improvement. During the grinding work, the infrared sensor scans and detects the bottom of the machine head. When the human body is detected, a signal is sent to the single-chip microcomputer to make it turn on the breaker for work. After it works, disconnect the circuit of the third motor, so that the grinding tool stops rotating, and at the same time, the single-chip microcomputer turns on the alarm to work, and sends out an audible and visual alarm to warn, thus solving the problem that the human body accidentally touches the grinding tool when the machine is running Afterwards, safety accidents are prone to occur, and the safety is not high; when the workpiece is being ground, the air compressor pump is turned on, and the gas in the gas storage box is pumped out and pressurized, and then transported to the spray nozzle by the gas pipeline. At the air pipe, it is sprayed from the nozzle at the bottom to the contact between the grinding tool and the workpiece, and the waste chips on the surface are blown to the waste chip inlet and fall, and then collected by the collection tube, thus solving the problem of grinding the workpiece. A large amount of waste will be generated, which is not easy to collect and clean, and adheres to the workpiece, which affects the grinding quality of the workpiece; when changing the workpiece, turn on the fourth motor to drive the screw to rotate, and its slide plate is threaded with the screw. And it is slidingly connected with the slide rail, so that the slide plate moves to the front of the fixed part, and the clamper is transported to the outside, which changes the original equipment and requires the staff to replace the workpiece inside the machine, which is inconvenient to install and prone to safety accidents , which makes it more convenient to replace the workpiece and increases the speed of workpiece replacement, improving safety and work efficiency; after the workpiece is clamped and fixed, the appropriate angle of the workpiece can be adjusted, first turn to loosen the locking bolt, and then turn the adjustment plate to drive The clamper adjusts the left and right angles, so that the angle of the workpiece can be adjusted left and right, and the pointer points to the scale number, which can quickly understand the angle of the workpiece adjustment, thus solving the problem that after the workpiece is clamped and fixed, the left and right angles cannot be changed, and the flexibility is insufficient. The problem of low work efficiency, increased flexibility and work efficiency
