Description

Technical Field

[0001] This utility model relates to the technical field of screw feeding devices, specifically a lathe feeding device for screw processing. Background Technology

[0002] Screws are indispensable industrial necessities in daily life: extremely small screws are used in cameras, eyeglasses, watches, and electronics; general screws are used in televisions, electrical products, musical instruments, and furniture; large screws and nuts are used in engineering, construction, and bridges; and screws of various sizes are used in transportation equipment, airplanes, trams, and automobiles. Screws play an important role in industry, and as long as industry exists on Earth, the function of screws will always be important. When processing screws, a lathe is needed to cut them. Lathe processing requires a stable feeding device. Traditional feeding devices are mostly fixed in their conveyor frame, which makes it inconvenient to adjust according to the screw specifications, resulting in poor practicality. Therefore, we propose a lathe feeding device for screw processing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a lathe feeding device for screw processing. The device uses an adjustable conveyor frame to feed screws of different specifications, while the brush and limit frame can sweep the screws to limit their movement. This makes the screw feeding more stable and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lathe feeding device for screw processing, comprising a housing and a feeding unit;

[0005] Box body: A material trough is provided on the top surface, and a main motor is fixed on the rear side of the box body. The output shaft of the main motor is connected to the rear side of the feeding tray.

[0006] Feeding unit: includes a conveyor frame, a fixed base, springs, a placement groove and a vibrating motor. The placement groove is opened on the front side of the box. Springs are fixed on both the left and right sides inside the placement groove. The inner ends of the springs are respectively installed on the left and right sides of the fixed base. Two conveyor frames are slidably installed inside the fixed base. The top surface of the conveyor frame is inclined from back to front. The vibrating motor is fixed on the bottom surface of the fixed base. The side of the fixed base is provided with a limiting unit.

[0007] It also includes a controller, which is located on the front side of the top surface of the housing. The input terminals of the main motor and the vibration motor are electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power source.

[0008] The main motor is started to drive the feeding tray to rotate and put the screws into the two conveyor frames. The vibrating motor, together with the spring, drives the conveyor frames to vibrate, which can feed and transport the screws on the conveyor frames.

[0009] Furthermore, the feeding unit also includes a support plate, a frame, a counting sensor, a mounting base, and a sensing sensor. The support plate is fixed to the front side inside the material trough, and a mounting base is fixed to the center of the top surface of the support plate. A sensing sensor is placed inside the mounting base. The frame is located on the bottom surface of the support plate, and a counting sensor is placed inside the frame. The output terminals of the counting sensor and the sensing sensor are electrically connected to the input terminal of the controller. The sensing sensor can detect the screws being fed, thus enabling automatic replenishment. The counting sensor can detect the number of screws being fed, facilitating recording by personnel.

[0010] Furthermore, the feeding unit also includes screws, guide plates, and rubber pads. There are two screws, each rotatably mounted on the outer side of a corresponding conveyor frame. The screws are threadedly connected to the screw holes on the surface of the fixed base. There are two guide plates, each mounted on the rear side of the top surface of a corresponding conveyor frame. Rubber pads are adhered to the top surface of the guide plates. Rotating the screws can adjust the position of the conveyor frames to meet the feeding and conveying of screws of different specifications.

The motor is fixed to the rear side of the top surface of the support plate. The output shaft of the motor is connected to the middle of the top surface of the brush. The input end of the motor is electrically connected to the output end of the controller. Starting the motor drives the brush to rotate and sweep the screw. The contraction of the second spring causes the limiting frame to press against the surface of the screw, thus limiting the screw and preventing it from protruding and affecting subsequent material feeding.

[0012] Furthermore, it also includes a transparent cover and lighting. The transparent cover is hinged to the top surface of the box, and there are two lighting lamps installed on the left and right sides inside the material trough, respectively. The input end of the lighting lamp is electrically connected to the output end of the controller.
