Description

Technical Field

[0001] The invention relates to a spring hook installation device, in particular to a spring hook installation machine and a spring hook assembly method. Background Art

[0002] Spring hooks are a common hardware product, widely used in products such as mountaineering buckles, rope buckles, pet chains, key accessories, special-shaped chains, luggage buckles, connecting hooks, and anti-skid chains. Spring hooks are mostly gourd-shaped, with a C-shaped long section and a straight short section hinged into a closed loop by rivets. Existing spring hooks usually include a long section and a short section. The long section is provided with an upper notch and a lower notch, and the short section is provided with a lower notch and a mounting groove. The mounting groove is provided with a spring and a spring washer. The spring washer is inserted into the spring, and the upper notch of the long section is inserted into the spring washer and hinged with the short section at this end, so that when the short section is pressed to insert into the rope or other spring hook, the short section will reset and self-lock under the action of the spring and the spring washer, and the lower notch of the short section matches the lower notch of the long section and is at the other end where the long section and the short section are relatively hinged. In the actual production process, since the mounting hole is small and the short section of the spring hook needs to maintain a certain elastic force, the spring washer and the spring are small in size and have elastic force, it is very difficult to assemble the long section of the spring hook. If you are not careful, the spring washer and the spring will pop out of the short section.

The present invention also has the advantages of simple structure, convenient assembly, reliable action, long service life, etc.

[0050] The mounting frame 71 is provided with a support mechanism 77, which includes a support block 771 and a support driving member 772. The support driving member 772 is connected to the support block 771 and is used to drive the support block 771 to move. The support block 771 is arranged below the clamping assembly 75.

[0051] The support driving member 772 is connected to the support block 771 through the sliding block 773. The support mechanism 77 includes a sliding sleeve 774. The support block 771 has a first position extending out of the sliding sleeve 774 for supporting the short section of the spring hook and a second position when retracted. After the long section of the spring hook is assembled, the support block is pushed out of the sliding sleeve 774 to push the assembled spring hook down, so that the product can be collected reliably.

[0052] The sliding sleeve 774 is fixed to the bottom of the mounting frame 71, the sliding block 773 and the supporting block 771 are both arranged in the sliding sleeve 774 and slideably cooperate with the sliding sleeve 774, the sliding block 773 is provided with a driving groove 7731 or a driving block 7711, the supporting block 771 is provided with a driving block 7711 or a driving groove 7731, the driving groove 7731 and the driving block 7711 cooperate with each other so that the movement direction of the sliding block 773 and the movement direction of the supporting block 771 are mutually perpendicular. Specifically, the driving groove drives the driving block to move through the sliding of the sliding block, thereby realizing the linear movement of the supporting block, the product has a simple structure, convenient operation, and reliable control, specifically, the supporting block can be made to tend to the first position by an elastic member, etc., more specifically, the driving groove is arranged in an arc shape or an inclined surface.

[0053] The clamping assembly 75 includes a clamping block 751, a pressure block 752 and a clamping elastic member 753. The pressure block 752 cooperates with the clamping block 751 to form a clamping space 754 for clamping the spring hook short section. The clamping elastic member 753 abuts against the pressure block 752 and has a movement tendency that makes the pressure block 752 move toward the clamping block 751. Specifically, the clamping block can be an integrated structure with the mounting frame. Such a structure can reliably drive the clamping assembly to clamp the material, and make the clamping block tend to clamp, so that the clamp can operate reliably in the machine.

[0054] The mounting frame 71 is provided with a fixing block 78, and the fixing block 78 is provided with a push rod slider 781 that slides and cooperates with the fixing block 78. The second driving member 742 is connected to the push rod slider 781 and is used to drive the push rod slider 781 and the second push rod 741 to move linearly. In this way, the second push rod can be reliably driven to move by the second driving member, and the push rod elastic member can keep the second push rod in an ejected state, and can support the spring pad when in use.

[0055] The mounting frame 71 is provided with a movable block 782 that matches with the push rod slider 781.

Specifically, the movable block 782 is provided with a push rod elastic member 7821 and a limit block 7822 that facilitates the push of the second driving member 742. The push rod elastic member 7821 is connected to the mounting frame 71 and has a movement tendency to drive the second push rod 741 toward the first position through the movable block 782. Such a structure enables the second driving member to reliably push the movable block, and the limit block facilitates the push.

[0056] The first push rod 731 is disposed below the second push rod 741, and the first push rod 731 passes through the push rod slider 781 and is driven by the first driving member 732 to move linearly relative to the push rod slider 781. The first push rod can reliably support the spring, making it easier for the spring washer to cooperate with the spring.
