The top end of the hook body is connected to one end of the hook tongue via a first pin, allowing the hook tongue to rotate around the first pin. The tail end of the hook body is the hook opening, and the bottom end of the hook tongue is the tongue opening. The hook opening has a protruding structure, and the tongue opening has a groove, with the protruding structure of the hook opening engaging with the groove of the tongue opening. A notch is also provided on one side of the hook tongue. The self-locking safety device includes a safety body, a spring, and a first cylindrical pin. The safety body has a T-shaped structure, with its left side engaging with the notch of the hook tongue and its right side having a thumb-shaped arc structure. One side of the spring abuts against the safety body, and the other side of the spring contacts the hook body. The groove designed at the tongue opening of this invention engages with the protruding structure designed at the hook opening of the hook body, effectively preventing the hoisted goods from detaching, improving the load-bearing capacity of the safety hook, and increasing the safety factor of the safety hook.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0029] The safety hook latch milling positioning and fixing fixture includes a base 1. A support plate 2 is fixedly mounted on the base 1. A limit plate 3 is mounted on the upper part of the support plate 2. A bracket 4 is mounted between the limit plate 3 and the base 1 via a lifting structure. A top block 5 is hinged to the bracket 4. A Y-axis power component 6 for driving the bracket 4 to lift is fixedly mounted on the base 1. A positioning shaft 7 is fixedly mounted on the inner side of the right support plate 2. An X-axis power component 8 is fixedly mounted on the base 1 to the left of the support plate 2 via a fixed structure. The X-axis power component 8 has an insertion positioning shaft 7. The slide 10 is also equipped with a claw 9 with a slot 11. The claw 9 is connected to the positioning shaft 7 by a plug-in structure. The positioning shaft 7 passes through the shaft holes of multiple hook tongues, and the top block 5 presses the hook tongues onto the limiting plate 2. Then, the X-axis power component 8 is used to press the hook tongues and the claw 9 together. Multiple hook tongues are positioned and fixed in multiple dimensions, reducing the positioning and fixing time of the hook tongues and improving milling efficiency. In addition, the bracket 4 is hinged to the top block 5. Even if there is a dimensional error between two hook tongues, it can be balanced by the hinge structure to ensure that they are pressed under the limiting plate 3, which improves the stability of the hook tongues after fixing.

[0030] It should be noted that the support plate 2 has two parallel sliding grooves 12 along the Z direction. Bolts are installed in the sliding grooves 12. One end of the bolt passes through the sliding groove 12 and is connected to the limiting plate 3 by thread engagement. By setting the sliding grooves 12, the limiting plate 3 can be adjusted to meet the positioning and fixing of hooks of different sizes, thereby improving practicality.

[0031] Specifically, the bracket 4 and the top block 5 are connected by a hinged shaft, and a cotter pin is provided on the shaft to facilitate the replacement of the top block 5 for maintenance.

[0032] To improve structural stability, the bracket 4 is U-shaped and the lower end face of the top block 5 is arc-shaped, which can improve the rotation angle of the top block. The top block 5 is set along the X direction.

[0033] Specifically, the Y-axis power component 6 is a cylinder, and the cylinder output shaft is connected to the bracket 4. There are two cylinders, which can simultaneously satisfy the positioning and fixing of four hooks.

[0034] It should be noted that the X-axis power component 8 is a hydraulic cylinder, and the output shaft of the hydraulic cylinder is provided with a slide 10, which can fix the free end of the positioning shaft 7.

[0035] Specifically, the chuck 9 includes a plate 91, a connecting rod 92, and several spaced-apart chuck blocks 93. The chuck blocks 93 are connected to the plate 91 via the connecting rod 92 through a fixed structure. The cavity between two adjacent connecting rods 92 and chuck blocks 93 is a chuck groove 11. The connecting rods 92 are fixedly provided with stop bars 94 on both sides. The chuck 9 can quickly separate multiple hooks, facilitating milling operations. The stop bars 94 can hook and push the lower part of the hooks to fit against the limiting plate 3, facilitating the clamping of the subsequent top block.

[0036] In order to increase the contact area with the upper surface of the hook tongue and improve the stability after fixing, the lower end face of the limiting plate 3 near the positioning shaft 7 is provided with an inclined surface 13.

[0037] The working principle and process of this utility model are as follows:

[0038] like Figure 4 As shown, firstly, the four hook tongues are sleeved on the positioning shaft 7 through the shaft hole. Then, the adjacent hook tongues are separated by the locking block 93, and the locking claw 9 is pressed down by the plate 91. Then, the hook tongues are rotated around the positioning shaft 7 by the stop rod 94, so that the tail of the hook tongues is close to the limiting plate 3. Then, the hydraulic cylinder 8 and the air cylinder 6 are started. The air cylinder 6 drives the bracket 4 and the top block 5 to move upward until the tail of the hook tongues is pressed tightly on the limiting plate 3 by the top block 5. The slide 10 on the output shaft of the hydraulic cylinder 8 is connected to the positioning shaft 7. The end face of the output shaft of the hydraulic cylinder 8 continues to press the hook tongues and the locking block 93 to complete the fixing work. The four hook tongue locks are milled simultaneously by the milling cutter.
