Description

Technical Field

[0001] The invention relates to the technical field of tightening shaft auxiliary equipment, and in particular to a tightening shaft quick-change tool. Background Art

[0002] Threaded connection is one of the most common ways to connect machine parts. It has the advantages of high precision, convenient assembly, easy maintenance, and high degree of standardization. Therefore, it is one of the most economical and widely used manufacturing methods in modern machine manufacturing. However, the failure of threaded connection is also one of the common machine failures. Therefore, countries around the world attach great importance to the research on the mechanism and failure causes of threaded connection. On this basis, they continue to develop thread tightening technology and control methods, apply advanced microelectronics technology and computer technology, and produce a new generation of CNC bolt tightening machines.

[0003] At present, when the existing tightening shaft machine is in use, the mounting frame is connected to the frame of the tightening machine, the fixed part of the brake unit is connected to the mounting frame, and the reaction force part is connected to the movable part of the brake unit. This realizes that before tightening the bolt output torque of the axial equipment to be assembled, the brake unit can be started so that its movable part is connected to the fixed part, so that the reaction force part is fixed and pressed against the equipment to be assembled. Furthermore, in the process of tightening the bolt output torque of the axial equipment to be assembled, the reaction force part can offset the reaction force generated by the tightening shaft on the equipment to be assembled during the process of tightening the bolt, thereby ensuring that the equipment to be assembled will not rotate, so that the tightening action can be completed smoothly and the operation is convenient.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] The replacement of tightening shafts is cumbersome: During the installation process, since there are many types of bolts that need to be tightened, there are certain differences in size and shape. Therefore, it is necessary to use two or more tightening shafts of different specifications at the same time. When switching between each tightening shaft, the user needs to spend a lot of time and energy to disassemble (or install), which seriously affects the efficiency of installation. For this reason, we propose a tightening shaft quick-change tooling. Summary of the invention

[0006] 1. Technical issues to be solved

[0007] In view of the deficiencies in the prior art, the present invention provides a tightening shaft quick-change tool to solve the technical problem that a lot of time and effort is required when replacing the tightening shaft of the existing tightening machine.

[0008] (II) Technical solution

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] A fast-changing tool for tightening a shaft, the tool comprising a base and a main board connected to each other, and the base and the main board are connected to form an "L" shape, such as Figure 1 As shown, a bolt hole is provided on the top of the base to facilitate connection with the tightening shaft through bolts, and a joint is connected to the outside of the main board, and the main board is connected to the vertical tightening arm through the joint, and a movable pin is provided on the outside of the joint. By rotating the movable pin, the vertical tightening arm and the tooling are connected together, as shown Figure 4 As shown;

[0011] A base, on which the main board is connected and which is perpendicular to the base;

[0012] Among them, the base is connected to the tightening shaft, the main board is connected to the tightening arm, a joint is connected to the main board, and the main board is connected to the tightening arm through the joint. After the vertical tightening arm is inserted into the joint, the movable pin outside the joint is rotated so that one end of the movable pin is inserted into the joint, thereby squeezing and fixing the vertical tightening arm inside the joint. Figure 1 shown.

[0013] Preferably, a movable pin hole is provided on the outer wall of the joint, and a movable pin is threadedly connected to the inside of the movable pin hole. Since the movable pin and the movable pin hole are threadedly connected, when the movable pin is rotated, the movable pin can be driven to move forward and backward along the movable pin hole (central axis), thereby connecting or loosening the tightening arm.

[0014] Preferably, the main board and the base are perpendicular to each other and have an "L" shape, which avoids the relative influence between the tightening arm and the tightening shaft, and at the same time can transmit the reaction force generated when the tightening shaft is tightened to the tightening arm, providing stability for the tightening shaft connection.

[0015] Preferably, two side panels (similar to reinforcing ribs) are connected between the base and the main board, and the two side panels are respectively located on both sides of the base. Figure 1 As shown, it is used to maintain the stability of the connection between the base and the motherboard.

[0016] Preferably, the outside of the side panel is plugged with a cylindrical pin, and the side panel is connected to the base and the main board respectively through the cylindrical pin. When in use, the side panel is first docked with the designated position of the base, and then the cylindrical pin is inserted into the outer wall of the side panel, and the cylindrical pin is inserted into the connection between the side panel and the base (that is, one end of the cylindrical pin is plugged into the side panel, and the other end is plugged into the side panel), forming Figure 2 The shape shown is used to connect the side panel and the base together. Similarly, the main panel and the side panel are connected together to facilitate subsequent welding.

[0017] Preferably, a welding strip is provided at the connection between any two adjacent components, so as to weld any two adjacent components together.

[0018] (III) Beneficial effects

[0019] Since the tightening shaft is installed on the tightening arm by using a joint, when the tightening shaft needs to be replaced, it is only necessary to rotate the movable pin. Therefore, the technical problem that a lot of time and energy need to be spent when replacing the tightening shaft in the existing tightening machine is effectively solved, and the vertical tightening arm can quickly replace the tightening shaft, adapt to the tightening process requirements, and improve work efficiency.

[0026] The embodiment of the present application solves the technical problem that a lot of time and effort need to be spent on replacing the tightening shaft of the existing tightening machine by providing a tightening shaft quick-change tool. When the tightening shaft is replaced by the vertical tightening arm, a joint is used to install the tightening shaft on the tightening arm. When the tightening shaft needs to be replaced, it is only necessary to rotate the movable pin, so that the vertical tightening arm can quickly replace the tightening shaft, adapt to the tightening process requirements, and improve work efficiency.

[0027] The technical solution of this application is to solve the technical problem that a lot of time and effort is required when replacing the tightening shaft of the existing tightening machine. The overall idea is as follows:

[0028] In view of the problems existing in the prior art, the present invention provides a tightening shaft quick-change tool, which includes a base 1 and a main board 3 connected to each other, and the base 1 and the main board 3 are connected to form an "L" shape, such as Figure 1As shown, a bolt hole is provided on the top of the base 1 to facilitate connection with the tightening shaft through bolts, and a joint 4 is connected to the outside of the main board 3, and the main board 3 is connected to the vertical tightening arm through the joint 4, and a movable pin 8 is provided on the outside of the joint 4. By rotating the movable pin 8, the vertical tightening arm and the tooling are connected together, as shown in FIG. Figure 4 As shown;

[0029] A base 1, on which a main board 3 is connected, which is perpendicular to the base 1;

[0030] Among them, the base 1 is connected to the tightening shaft, the main board 3 is connected to the tightening arm, the main board 3 is connected to the joint 4, and the main board 3 is connected to the tightening arm through the joint 4. After the vertical tightening arm is inserted into the joint 4, the movable pin 8 outside the rotating joint 4 is inserted into the joint 4, so that one end of the movable pin 8 is inserted into the joint 4, thereby squeezing and fixing the vertical tightening arm inside the joint 4. Figure 1 shown.

[0031] In some examples, the outer wall of the joint 4 is provided with a movable pin hole 7, and the movable pin hole 7 is threadedly connected with a movable pin 8. Since the movable pin 8 and the movable pin hole 7 are threadedly connected, when the movable pin 8 is rotated, the movable pin 8 can be driven to move forward and backward along the movable pin hole 7 (central axial direction), thereby connecting or loosening the tightening arm. The main board 3 and the base 1 are perpendicular to each other and are in an "L" shape to avoid relative influence between the tightening arm and the tightening shaft, and at the same time, the reaction force generated when the tightening shaft is tightened can be transmitted to the tightening arm, providing stability of the tightening shaft connection.

[0032] In some examples, two side panels 2 (similar to reinforcing ribs) are connected between the base 1 and the main board 3, and the two side panels 2 are respectively located on both sides of the base 1. Figure 1 As shown, it is used to maintain the stability of the connection between the base 1 and the main board 3. The side panel 2 is plugged with a cylindrical pin 5 on the outside, and the side panel 2 is connected to the base 1 and the main board 3 respectively through the cylindrical pin 5. When in use, the side panel 2 is first docked with the designated position of the base 1, and then the cylindrical pin 5 is inserted into the outer wall of the side panel 2, and the cylindrical pin 5 is inserted into the connection between the side panel 2 and the base 1 (that is, one end of the cylindrical pin 5 is plugged into the side panel 2, and the other end is plugged into the side panel 2), forming as shown in FIG. Figure 2 The shape shown is used to connect the side panel 2 and the base 1 together. Similarly, the main panel 3 and the side panel 2 are connected together to facilitate subsequent welding.

[0033] In some examples, welding strips 6 are provided at the connection between any two adjacent components, so as to weld any two adjacent components together.

[0034] When installing the device, first dock the side plate 2 with the designated position of the base 1, then insert the cylindrical pin 5 into the outer wall of the side plate 2, and insert the cylindrical pin 5 into the connection between the side plate 2 and the base 1 (that is, one end of the cylindrical pin 5 is plugged into the side plate 2, and the other end is plugged into the side plate 2), forming a Figure 2 The shape shown in FIG. 1 is formed so that the side plate 2 and the base 1 are connected together. Similarly, the main plate 3 and the side plate 2 are connected together. Then, the components are connected together by welding along the welding strip 6 to form a structure as shown in FIG. Figure 1 Shape shown.

[0035] When in use, first insert the tightening shaft into the through hole on the surface of the base 1, and then use bolts to connect the tightening shaft and the base 1 together. After completion, insert the end of the vertical tightening arm into the joint 4, and rotate the movable pin 8 outside the joint 4. Since the movable pin 8 and the movable pin hole 7 are connected by threads, when the movable pin 8 is rotated, the movable pin 8 can be driven to move forward along the movable pin hole 7 (central axial direction), thereby connecting the tightening arm. At this time, the tightening shaft and the tightening arm can be connected together to form a Figure 4 Shape shown.

[0036] When replacing, it is only necessary to rotate the movable pin 8 in the opposite direction so that the movable pin 8 moves backward along the movable pin hole 7 (central axial direction) to separate from the tightening arm. At this time, the tightening shaft can be removed from the tightening arm. Similarly, another tooling (with a tightening shaft of a different model installed) can be installed on the vertical tightening arm to complete the replacement of the tightening shaft.

[0037] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
