Description

TECHNICAL FIELD

[0001] The application relates to the spring hook production field, in particular to a spring hook deviation correction device. BACKGROUND

[0002] The spring hook is a common hardware product, which is widely used in mountaineering buckles, cord buckles, pet chains, key accessories, special-shaped chains, luggage buckles, connecting hooks, anti-skid chains and the like. The spring hook is mostly in the shape of a gourd, which is formed by a C-shaped long section and a straight short section being hingedly connected into a closed ring by a rivet. The long section and the short section are hingedly connected at one end by the rivet, and the other end of each is provided with a groove and a protrusion, so as to be engaged with each other to realize connection. After the spring hook is assembled, the spring hook usually needs to be detected, which includes pressing the short section to check whether the short section is convenient to open, whether the short section can be reliably reset under the action of a spring or a torsion spring, and whether the long section and the short section are deviated left and right.

[0003] The patent No. CN 202110286311.9 provides a spring hook testing machine, which comprises a testing device for pressing the short section of the spring hook and a detection device for detecting the closing condition of the short section of the spring hook, so as to detect the short section recovery closing condition after the testing device is pressed, thereby realizing sorting and screening. The spring hook testing machine only completes the basic screening, and the waste rate is high. If the long section and the short section are deviated left and right, the subsequent maintenance of the spring hook needs to be performed by manual work, which is troublesome, low in efficiency, large in subjectivity, high in labor cost, and cannot guarantee the product quality. SUMMARY

[0004] The application provides a spring hook deviation correction device, which is used for correcting the left and right deviation of the assembled spring hook, improving the production efficiency, guaranteeing the product quality and reducing the waste rate.

[0005] The spring hook deviation correction device provided by the application is installed corresponding to the clamping device on the rotating disc, and comprises a deviation correction tool and a rotating material transfer tool for transferring the spring hook between the clamping device of the rotating disc and the deviation correction tool; the deviation correction tool comprises a spring hook correction groove, a first correction support, a first correction driving member and a first correction pressing rod connected with the first correction driving member and used for pressing the short section of the spring hook; the deviation correction tool further comprises left and right symmetrically arranged deviation correction units, and each deviation correction unit comprises a deviation correction support, a deviation correction driving member and a deviation pushing rod connected with the deviation correction driving member and used for pushing the short section according to the deviation between the short section and the long section of the spring hook.

[0006] Further, the rotating transfer tool comprises a rotating transfer driving member and transfer clamping jaws connected to both sides of the top end of the rotating transfer driving member. The rotating transfer driving member can be combined by multiple air cylinders and is installed between the rotating disc and the correction tool. The rotating transfer driving member can rotate to drive the transfer clamping jaws to move away from or close to the clamping device, drive the transfer clamping jaws to clamp or release the spring hook, so as to realize the transfer between the clamping device on the rotating disc and the spring hook correction slot. The rotating transfer driving member comprises a first air cylinder at the bottom for driving in the height direction. A second air cylinder is installed above the first air cylinder. A connecting member is sleeved above the second air cylinder. Third air cylinders are connected to both sides of the connecting member. The third air cylinders can drive the transfer clamping jaws to release or close. The second air cylinder is used to drive the connecting member to move circumferentially, so as to rotate; and the transfer clamping jaws move between the clamping device and the correction tool.

[0007] Further, the spring hook correction slot is used to accommodate the spring hook to be corrected. The spring hook stands in the spring hook correction slot and the long section is attached to the bottom of the spring hook correction slot. The short section is higher than the slot opening of the spring hook correction slot, so that the first correction top pressing rod and the offset pressing rod can press or push the short section.

[0008] Further, the offset correction support is arranged on both sides of the spring hook correction slot. An offset correction driving member is arranged on one side of the offset correction support, and an offset pressing rod is arranged on the other side. The offset pressing rod is driven by the offset correction driving member to push the short section of the spring hook.

[0009] Further, the first correction driving member, the offset correction driving member and the rotating transfer driving member are composed of air cylinders. The rotating transfer driving member can be combined by multiple air cylinders to drive the transfer clamping jaws to complete the actions of up and down, rotation, clamping and separation. The first correction driving member and the offset correction driving member are each composed of a single air cylinder to drive the first correction top pressing rod and the offset pressing rod to move linearly.

[0010] In the present application, the offset refers to the left and right offset between the short section of the spring hook and the long section of the spring hook.

[0011] After the spring hook is transferred to the spring hook correction slot by the rotating transfer tool, the first correction driving member drives the first correction top pressing rod to press the short section several times. Then, if the short section is offset to the left relative to the long section, the left offset correction driving member drives the left offset pressing rod to push the short section to the right. If the short section is offset to the right relative to the long section, the right offset correction driving member drives the right offset pressing rod to push the short section to the left, so as to realize offset correction. After the offset correction is completed, the spring hook is transferred to the clamping device on the rotating disc by the rotating transfer tool.

[0012] The offset of the spring hook can be detected by a detection device arranged before the correction device, and the detection device uploads the detection result to a controller. The actions of the first correction driving member, the offset correction driving member and the rotary transfer driving member are all controlled by the controller.

[0013] The spring hook offset correction device provided by the embodiments of the present application can achieve the following beneficial effects:

[0014] The present application can correct the offset between the long section and the short section in a targeted manner, improve production efficiency, ensure product quality and reduce the waste rate. BRIEF DESCRIPTION OF DRAWINGS
