[0037] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0038] In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0039] Refer to Figures 1 to 12 , the present application provides a screw tightening tooling, including:

[0040] The length adjustment mechanism includes a first sleeve 1 and a second sleeve 2; one end of the first sleeve 1 is a first connection end 3, and an opening is provided at the other end of the first sleeve 1 for the second sleeve 2 to be inserted. A positioning pin 5 is provided on the outer wall of the second sleeve 2, and a sliding groove 6 is provided on the side wall of the first sleeve 1. The position of the positioning pin 5 in the sliding groove 6 is adjustable and fixed, so that after the first sleeve 1 and the second sleeve 2 are telescoped to a predetermined length, they are locked.

[0041] It should be noted that both the first sleeve 1 and the second sleeve 2 are made of Q235A carbon steel. Considering that Q235A carbon steel has good toughness and plasticity, a certain elongation rate, good welding performance and hot workability, it is convenient for processing.

[0042] The angle adjustment mechanism, such as Figure 7 and Figure 8 shown, includes a first tooth surface seat 7 and a second tooth surface seat 8; one side of the first tooth surface seat 7 is connected to the second sleeve 2, the other side of the first tooth surface seat 7 is meshed and connected to the second tooth surface seat 8, and a second connection end 4 is provided on the side of the second tooth surface seat 8 away from the first tooth surface seat 7; by rotating the first tooth surface seat 7 or the second tooth surface seat 8, the meshing position of the first tooth surface seat 7 and the second tooth surface seat 8 is adjusted to adjust the angle between the first tooth surface seat 7 and the second tooth surface seat 8;

[0043] The rotating mechanism is connected to the first connection end 3 and controls the rotation of the first connection end 3, thereby driving the second connection end 4 to rotate; or is connected to the second connection end 4 and controls the rotation of the second connection end 4, thereby driving the first connection end 3 to rotate.

[0044] In an implementable manner, as Figure 5 shown, the sliding groove 6 includes an elongation section 61 and a positioning section 62. The elongation section 61 is arranged along the axial direction of the first sleeve 1, and the positioning section 62 is perpendicular to the elongation section 61. When the positioning pin 5 slides into the positioning section 62, the length of the length adjustment mechanism is fixed.

[0045] In an implementable manner, the sliding groove 6 includes a plurality of positioning sections 62, so that the length adjustment mechanism has a variety of adjustable lengths, increasing the scope of use.

[0046] In an implementable manner, as Figure 6 shown, a spring 9 is inserted into the first sleeve 1. One end of the spring 9 abuts against the first sleeve 1, and the other end of the spring 9 abuts against the insertion end. Through the arrangement of the spring 9, it is convenient to reset the first sleeve 1 and the second sleeve 2 after use, which is beneficial for the next use.

[0047] It should be noted that the spring 9 is made of 65MN spring steel. Considering that after heat treatment and cold drawing hardening, 65MN spring steel has relatively high strength, good flexibility and plasticity.

[0048] In an implementable manner, the first tooth surface seat 7 and the second tooth surface seat 8 are locked by a locking member.

[0049] In an implementable manner, as Figure 2 shown, the locking member includes a connecting rod 10. Both ends of the connecting rod 10 are hinged to the outer sides of the first tooth surface seat 7 and the second tooth surface seat 8 respectively. A positioning bead is arranged on one side of the connecting rod 10 close to the first tooth surface seat 7. As Figure 7 shown, a plurality of positioning grooves 11 are arranged on the side surface of the first tooth surface seat 7. One side of the positioning bead is fixedly connected to the connecting rod 10, and the other side of the positioning bead protrudes for being clamped in the positioning groove 11. After adjusting the angle between the first tooth surface seat 7 and the second tooth surface seat 8, the positioning bead is clamped in a predetermined positioning groove 11 to limit the rotation between the first tooth surface seat 7 and the second tooth surface seat 8 and keep the angle between the first tooth surface seat 7 and the second tooth surface seat 8 unchanged.

[0050] Specifically, the adjustment angles corresponding to the plurality of positioning grooves 11 are 0°, 30°, 45°, 60° and 90° respectively. By setting a plurality of predetermined angles, the application range of the present application can be increased, and the needs of different projects can be flexibly met.

[0051] It should be noted that both the connecting rod 10 and the positioning bead are made of Q235A carbon structural steel. Considering that Q235A carbon steel has good toughness and plasticity, a certain elongation rate, good welding performance and hot workability, which is convenient for processing.

[0052] In an implementable manner, as Figure 9 and Figure 10 shown, the first tooth surface seat 7 includes a first flange fork head 12, and the second tooth surface seat 8 includes a second flange fork head 13. A double universal joint structure is formed after the first flange fork head 12 and the second flange fork head 13 are connected by a cross shaft. The free end of the second flange fork head 13 is the second connection end 4. By setting the double universal joint structure, normal transmission of rotation can be achieved after setting an included angle between the first tooth surface seat 7 and the second tooth surface seat 8.

[0053] It should be noted that the first flange fork head 12 can rotate within the first tooth surface seat 7, and the second flange fork head 13 can rotate within the second tooth surface seat 8.

[0054] In an implementable manner, the cross shaft at least includes a grooved transmission shaft 14 and a stroke transmission shaft 15; one end of the grooved transmission shaft 14 is a hollow shaft, and a plurality of strip grooves are provided on the outer wall of the hollow shaft. A plurality of guiding strips are provided on the outer surface of the stroke transmission shaft 15. The stroke transmission shaft 15 is inserted into the grooved transmission shaft 14 so that the guiding strips are correspondingly clamped in the strip grooves. Through the setting of the cross shaft, by changing the length of the stroke transmission shaft 15 inserted into the grooved transmission shaft 14, the position change caused by the angle adjustment between the first tooth surface seat 7 and the second tooth surface seat 8 is adapted, and it is ensured that there is no rotation between the grooved transmission shaft 14 and the stroke transmission shaft 15.

[0055] In an implementable manner, a connecting shaft is inserted into the first sleeve 1. The connecting shaft sequentially passes through the first sleeve 1 and the second sleeve 2 and then extends out of the second sleeve 2; one end of the connecting shaft is a first connecting end 3, and the other end extends out of the second sleeve 2 and is hinged to the first flange fork head 12. The connecting shaft is used to transmit torque.

[0056] In an implementable manner, the connecting shaft is a pull-out type connecting shaft, which at least includes a first shaft section 16 and a second shaft section 17; one end of the second shaft section 17 is a hollow shaft, and the first shaft section 16 is inserted into the second shaft section 17; a flat key is provided on the inner wall of the second shaft section 17, and a flat key groove is provided at the corresponding position on the first shaft section 16. The flat key is arranged in the flat key groove, and only torque is transmitted after the first shaft section 16 and the second shaft section 17 are connected. Through the setting of the pull-out type connecting shaft, on the premise of ensuring normal torque transmission, the length of the connecting shaft can be adjusted along with the length adjustment mechanism.

[0057] It should be noted that as Figures 1 to 3 shown, the first connecting end 3 and / or the second connecting end 4 is a hexagonal connecting end. The hexagonal connecting end is used to connect with the component to be installed or with the power component, so that both ends of the present application can be connected with the component to be installed. It is also possible to set the first connecting end 3 and the second connecting end 4 as connecting heads of different specifications to increase the application range of the present application.

[0058] It should also be noted that the connecting shafts are all made of 45# steel. Considering that 45# steel has good plasticity and toughness, high strength, high recovery rate, has relatively high strength and good machinability, and can obtain excellent physical and mechanical properties under different heat treatments.

[0059] In an implementable manner, as Figure 6 shown, the first shaft section 16 is connected to the first sleeve 1 through a first shaft sleeve 18, and the second shaft section 17 is connected to the second sleeve 2 through a second shaft sleeve 19, so as to avoid wear of the first sleeve 1 or the second sleeve 2 when the connecting shaft rotates.

[0060] It should be noted that the second bushing 19 is an oil-free bushing, and both the first bushing 18 and the second bushing 19 are made of H62 brass, which has good mechanical properties.

[0061] In summary, the present application provides a screw tightening tooling. Through the setting of the length adjustment mechanism, length adjustment can be achieved, and it can adapt to different scenarios on the ship. By setting the positioning section 62 on the sliding groove 6, locking can be performed after the length adjustment is completed. Through the setting of the angle adjustment mechanism, the installation angle of the tooling can be adjusted to adapt to different installation scenarios on the ship. Through the setting of the first connection end 3 and the second connection end 4, the torque can be stably transmitted to disassemble and assemble screws of different specifications. Through the setting of the positioning beads and the plurality of positioning grooves 11, angle locking can be performed after the angle adjustment is completed. This application can be used in relatively dangerous areas on the ship, replacing manual disassembly and assembly of bolts, avoiding physical injuries to construction workers, improving work efficiency, and ensuring work quality; this application has strong safety, a simple structure, is convenient to use, and is conducive to popularization and use.

[0062] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
