Description

Technical Field

[0001] The utility model relates to the technical field of mechanical assembly, in particular to a mechanical assembly fastening connector. Background Art

[0002] Fasteners are commonly used connectors in mechanical equipment. They ensure a tight connection between two or more cooperating parts. Mechanical equipment is made up of a variety of different mechanical parts that are connected to each other. Different parts require different structural components to assemble and connect.

[0003] Existing connectors adopt a single form of connection structure, such as a mechanical assembly fastening connector disclosed in announcement number CN213981633U, which sets a pad at the front end of the bearing groove on both sides, so that it is fixed to the front side of the bearing groove by inserting a column into the slot. After the bearing is placed in the bearing groove and the connector is connected to the mechanical equipment, the pad is attached to the surface of the connecting plate and locked when the two rotate, avoiding wear on the surface of the connecting plate. However, screw fixing is the most common method for fixing mechanical components. Although simple, the operation of tightening a large number of bolts and screws is very time-consuming and labor-intensive, and also has certain requirements on the degree of connection assembly, making the connection method between mechanical components extremely single and unable to meet diverse assembly needs.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Refer to Figure 1-Figure 4 , a mechanical assembly fastening connector, including a connection end 1. A first set hole 2 and a first locking hole 3 that are connected and communicated are opened in one end of the connection end 1, and a thread cavity 4, a guide hole 5 and a second locking hole 6 that are connected and communicated are opened in the other end of the connection end 1. The connection end 1 is fixedly connected to a mechanical component through the first set hole 2.

[0022] An engagement mechanism is provided on the connection end 1 through the thread cavity 4, the guide hole 5 and the second locking hole 6. The connection end 1 adjusts the length of the telescopic rod 8 through the engagement mechanism so as to assemble and connect another mechanical component according to actual needs. Specifically, refer to the attached drawings of the specification Figure 3 And the attached Figure 4 :

[0023] On the one hand, the engagement mechanism includes a thread plug 7 threadedly connected to the thread cavity 4. A telescopic rod 8 is fixedly connected to the thread plug 7. A load-carrying turntable 9 is rotatably installed on the telescopic rod 8, and a guide rod 10 extending into the guide hole 5 is integrally connected to the load-carrying turntable 9. The guide rod 10 is fixed through the second locking hole 6 to ensure the fixed length of the telescopic rod 8. An engagement convex block 11 is integrally connected to the load-carrying turntable 9. A rear cavity 12, a C-shaped cavity 13 and a second set hole 14 that are sequentially connected and communicated are opened in the engagement convex block 11. Utilize the second set hole 14;

[0024] On the other hand, a handle 15 is rotatably installed in the rear cavity 12, and a ball screw 16 rotatably installed in the cavity 13 is fixedly installed on the handle 15. It should be noted that two damping bearings for rotatably supporting the ball screw 16 are fixedly provided in the connecting protrusion 11 to ensure that the ball screw 16 does not rotate on its own. A movable nut 17 is matched with the ball screw 16. A steering lever 18 movably pulled by the movable nut 17 is rotatably installed in the cavity 13. A locking plug 20 movably pulled by the steering lever 18 and extending to the second set hole 14 is slidably sleeved in the cavity 13. The locking plug 20 is driven to extend into the second set hole 14 to lock and fix another mechanical component sleeved in the second set hole 14.

[0025] The guide holes 5 are symmetrically arranged on both sides of the threaded cavity 4 , and the second locking hole 6 is located outside the guide hole 5 , so as to fix the length of the guide rod 10 that is telescopic in the guide hole 5 .

[0026] The load turntable 9 is connected to one end of the telescopic rod 8 outside the threaded cavity 4, and the guide rod 10 is slidably sleeved in the guide hole 5 to provide a guiding and limiting function for the telescopic rod 8 in spiral motion.

[0027] A traction link 19 is connected to the pin between the movable nut 17 and one end of the steering lever 18. A traction long hole 21 is opened in the other end of the steering lever 18, and a sliding sleeve is integrally connected to the locking bolt 20 with a traction long bolt 22 in the traction long hole 21. By driving the steering lever 18 to deflect, the locking bolt 20 can realize linear reciprocating telescopic movement adjustment in the cavity 13 and the second set hole 14.

[0028] The locking bolt 20 has a Y-shaped structure, which ensures that the steering lever 18 can smoothly pull and drive the locking bolt 20 .

[0029] It should be noted that the specific model and specifications of the connecting terminal 1 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0030] The functional principle of this utility model can be explained through the following operation modes:

[0031] Insert one of the mechanical components into the first inserting hole 2 and lock and secure the mechanical component in the first locking hole 3;

[0032] Screw the telescopic rod 8 in the other end of the connecting end 1 to make the threaded plug 7 and the threaded cavity 4 move spirally, so that the engaging protrusion 11 moves to the required length;

[0033] Another mechanical component is mounted through the second mounting hole 14, and the ball screw 16 is screwed through the handle 15 to move the movable nut 17. The movable nut 17 drives the steering lever 18 to deflect through the pulling link 19. The steering lever 18 drives the locking bolt 20 to extend into the second mounting hole 14 through the pulling long bolt 22 to lock and fix the mechanical component.
