Description

Technical Field

[0001] The utility model belongs to the technical field of spring detection, and particularly relates to a spring screening machine. Background Technique

[0002] A spring is a mechanical part that works by using elasticity. A part made of elastic material deforms under the action of an external force and returns to its original state after the external force is removed. It is generally made of spring steel. Springs are complex and diverse in types. According to the shape, there are mainly helical springs, scroll springs, leaf springs, and special-shaped springs, etc. When springs are produced and processed, the quality of the springs needs to be detected to realize the screening function of good and bad springs.

[0003] After retrieval, the patent publication number CN208555059U discloses a spring screening device, which includes a frame, a rotary mechanism and a camera respectively installed on the frame, and a screening mechanism. The rotary mechanism includes a turntable rotatably arranged on the frame. The camera is located above the turntable. The screening mechanism includes a receiving bin located below the turntable, a distributing bin located below the receiving bin, a first blanking bin and a second blanking bin, an electromagnet, a magnetic part and an elastic part arranged on one side of the distributing bin. The receiving bin and the distributing bin are both inclined at a high and low level. The upper end of the distributing bin is hinged to the lower end of the receiving bin. The lower end of the distributing bin is provided with a distributing port. The first blanking bin is provided with a first blanking port, and the second blanking bin is provided with a second blanking port. The first blanking port and the second blanking port are respectively located on both sides below the distributing port. The magnetic part is arranged on the distributing bin corresponding to the electromagnet, and the elastic part elastically abuts between the electromagnet and the distributing bin. The utility model realizes the spring screening function by deflecting the distributing bin, with convenient operation and high efficiency.

[0004] In actual implementation of the above technical solution, although it can realize the automatic detection of the appearance of the spring, during the screening process, due to the elastic factor of the spring itself, the spring cannot accurately fall into the receiving bin, and the overall structure of the device is relatively complex, with a high manufacturing cost. Therefore, we propose a spring screening machine to solve the existing problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a spring screening machine to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A spring screening machine, comprising a support plate: a top plate is installed at the top end of the support plate, a CCD camera is installed on the lower surface of the top plate, a computer is installed on the upper surface of the top plate, a turntable is arranged below the CCD camera, a connecting shaft is installed at the center position of the rear end wall of the turntable, the other end of the connecting shaft penetrates through a bearing on the end face of the support plate and is connected to a stepping motor through a coupling, mounting posts are installed on the outer wall of the turntable, guide plates are installed on both sides of the front end face of the support plate, a soft sponge pad and a baffle are installed on one side surface of the guide plate, and the baffle is located in front of the soft sponge pad, a mounting plate is installed below the front end face of the support plate, a qualified product collection tank and an unqualified product collection tank are respectively installed on both sides of the upper surface of the mounting plate.

[0008] Further, the stepping motor is installed on the upper surface of a support block, and the support block is installed on the rear end wall of the support plate.

[0009] Further, the bottom end of the support plate is installed at the rear end of the upper surface of a base, and support feet are installed at the four corners of the lower surface of the base.

[0010] Further, U-shaped handles are installed on the front end faces of the qualified product collection tank and the unqualified product collection tank.

[0011] Further, strip-shaped blocks are installed on both sides of the bottom ends of the qualified product collection tank and the unqualified product collection tank, and the bottom ends of the strip-shaped blocks are installed in strip-shaped slots.

[0012] Further, a clearance connection is provided between the outer wall of the strip-shaped block and the hole wall of the strip-shaped slot, and the strip-shaped slots are opened on both sides of the surface of the mounting plate.

[0013] Further, there are three mounting posts on the turntable, and the three mounting posts are distributed in a ring array.

[0014] With the above technical solution, the present utility model provides a spring screening machine, which has at least the following beneficial effects: Through the coordinated setting of a series of structures, when a staff member needs to detect the appearance of a spring, the staff member sleeved the spring on the mounting post, and the CCD camera detects the appearance of the spring on the mounting post. When the appearance of the spring is detected to be qualified, the stepping motor starts and drives the turntable to rotate counterclockwise by a certain angle. Then, due to its own gravity, the spring will slide out from the mounting post. When the spring slides onto the soft sponge pad on the guide plate, the setting of the soft sponge pad can effectively avoid the situation that the spring rebounds due to the collision between the spring and the soft sponge pad and splashes out. When the spring falls onto the soft sponge pad, it will slide into the qualified product collection tank along the inclination angle of the soft sponge pad. When the appearance of the spring is detected to be unqualified, the stepping motor starts and drives the turntable to rotate clockwise by a certain angle. Then, due to its own gravity, the spring will slide out from the mounting post. When the spring falls onto the soft sponge pad, it will slide into the unqualified product collection tank along the inclination angle of the soft sponge pad. Therefore, the present utility model can automatically detect the appearance of the spring and screen the qualified and unqualified springs, automatically screen the springs into the qualified product collection tank or the unqualified product collection tank, and effectively avoid the situation that the spring cannot accurately fall into the qualified product collection tank or the unqualified product collection tank due to its own elastic factor, with strong practicability.
