Description

Technical Field

[0001] This utility model relates to an automatic feed receiving device for machine tools. Background Technology

[0002] Typically, after a machine tool finishes processing a material, the material needs to be manually removed and placed into a storage box; and in most cases, this process involves processing once and retrieving the material manually once. Workers need to frequently load and unload materials. To reduce repetitive actions, this invention designs a material ejection and receiving structure. Workers only need to place the workpiece; after processing, the machine tool will eject the workpiece and drop it into the receiving box, greatly reducing the worker's workload. Furthermore, the receiving box can be flipped; after receiving materials multiple times, it can rotate and flip to send the material into the workpiece storage box, avoiding the tedious process of repeatedly storing materials.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings: An automatic material feeding and receiving device for a machine tool includes a material feeding device and a material receiving device 2. The material feeding device is located at the position directly opposite the tool holder, and the material receiving device 2 is located on one side of the material feeding device. Material receiving is achieved by rotation and flipping. The material feeding device is located in the positioning sleeve 10 of the locking device 4, and the locking device is installed on the machine tool 1.

[0014] Specifically, the receiving device consists of a first motor 5, a first bushing 6, a second motor 7, a rocker arm 8, and a receiving frame 9. The first motor 5 is mounted on the machine tool 1 on one side of the material ejector device. The first bushing 6 is mounted on the output shaft of the first motor 5, and the rotation of the first motor 5 can drive the first bushing 6 to rotate. The second motor 7 is vertically mounted on the side of the first bushing 6, and the rocker arm 8 is vertically mounted on the output shaft of the second motor 7. The receiving frame 9 is mounted at the end of the rocker arm 8. The axes of the first motor and the second motor are set at 90 degrees. The receiving frame can rotate axially under the drive of the first motor and can rotate around the output shaft of the first motor under the drive of the second motor. When the receiving frame is horizontal, it is located below the material ejector device. When the receiving frame is flipped to a vertical position, it cooperates with the discharge port 3 located on one side of the material ejector device.

[0015] Working process: During material receiving, the receiving frame is in its initial position, below the ejector device, and is horizontal. The finished workpiece falls into the receiving frame. After a period of operation, when the material in the receiving frame needs to be transferred, the first motor rotates, causing the receiving frame to rotate clockwise until it is on the same plane as the discharge port. Then, the second motor rotates, causing the receiving frame to flip upwards, thus pouring the workpiece into the discharge port. It should be noted that workpieces can be transferred one at a time, or transferred after a period of operation. Motor drive programs can be set according to different situations. Motor drive technology is existing and will not be elaborated upon here.

[0016] Specifically, the spring-loaded device includes a clamping rod 11, a locking sleeve 12, a limiting claw 13, a base plate 14, a limiting seat 15, a limiting sleeve 16, a spring rod 17, a spring 18, and a spring rod boss 19. The positioning sleeve 10 of the locking device has a hollow structure, and the clamping rod 11 is installed inside the positioning sleeve 10. A conical cavity is provided on the right side of the positioning sleeve 10 for connecting the limiting claw 13 to the right end of the clamping rod 11. The left end of the clamping rod 11 extends out of the positioning sleeve 10 and cooperates with the pulling device. When the pulling device pulls, the clamping rod will drive the limiting claw to move to the left, thereby locking the claw of the limiting claw into the workpiece 20. The pulling device is existing technology, and currently most of them use cylinders to push and pull to achieve the pulling effect, which will not be described in detail here.

[0017] A base plate 14 is provided between the clamping rod 11 and the limiting claw 13. A limiting seat 15 is provided on the right side of the base plate. The limiting seat 15 has external threads and a concave hole in its center to extend the stroke of the spring rod 17. The external threads of the limiting seat can be screwed into the limiting sleeve 16 located inside the limiting claw. A through hole is provided on the right side of the limiting sleeve 16. The right end of the spring rod 17 extends out of the through hole of the limiting sleeve and is exposed in the cavity of the limiting claw. A spring 18 is sleeved on the spring rod located inside the limiting sleeve. One end of the spring 18 is limited by the limiting seat, and the other end of the spring is limited by the spring rod boss 19 located on the spring rod. The diameter of the spring rod boss 19 is larger than the diameter of the through hole on the right side of the limiting sleeve. A locking sleeve 12 is fixed to the right side of the positioning sleeve 10 by bolts. The opening on the right side of the locking sleeve 12 is funnel-shaped, matching the shape of the multiple limiting claws. When the limiting claws move to the left, they are converged and locked along the funnel-shaped opening of the locking sleeve, and the workpiece located at the center of the limiting claws is pressed. A small protrusion 21 is provided on the right end of the clamping rod 11, and a small groove 22 is provided on the left end of the limiting claw 14. The clamping rod and the limiting claw are limited in the conical cavity on the right side of the positioning sleeve by the cooperation of the small protrusion and the small groove.

[0018] The working process of the spring feeding device is as follows: When the workpiece is placed in the limiting claw, the workpiece will push the spring rod to the left, the spring on the spring rod will be compressed, and at the same time the pulling device at the left end of the clamping rod will be pulled. The clamping rod moves to the left, which in turn drives the limiting claw to move to the left. After the limiting claw moves to the left, it clamps the workpiece, and the workpiece can be processed at this time. When the workpiece is processed, the pulling device at the left end of the clamping rod is reset, and the clamping rod will be driven to move to the right. At this time, the clamping limiting claw will be released, and the workpiece will be released. At this time, the spring on the spring rod will restore its deformation, push the spring rod to the right, and the spring rod will push the workpiece to the right, and then the workpiece will fall into the receiving frame.

[0019] The material ejector device of this utility model consists of a clamping rod, a limiting claw, a spring rod, and a spring. When the clamping rod is pulled by the pulling device, the limiting claw retracts into the locking sleeve under tension, thereby limiting the workpiece. At the same time, the workpiece presses against the spring rod, and the spring rod compresses the spring. When the workpiece is finished and the bolt locking the clamping rod is loosened, the limiting claw releases the workpiece, the spring returns to its original deformation, and pushes the spring rod to push the workpiece away from the workpiece clamping area. The workpiece falls into the receiving frame. The mechanical material ejector structure can reduce costs and avoid the increased cost of a large number of electrical control components. The receiving device consists of a receiving frame and a rotating assembly. During use, the receiving frame can collect the processed workpieces. When a sufficient number are collected, the rotating assembly drives the receiving frame to the discharge port, where the workpieces fall into the storage frame, thus realizing the external conveying of the workpieces inside the receiving frame.
