[0028] Example

[0029] See also Figure 1-Figure 3 The utility model provides a four-way joint clamping tool for helicopters. In practical application, it is used to solve the shortcomings of the prior art that the product clamping error leads to low overall processing efficiency. The utility model includes a mounting platform 1, a positioning shaft 2 and two fastening components 3.

[0030] It should be clear that, in the present invention, the cross-connector 4 to be processed is a semi-finished product in which a through hole has been formed through preliminary processing.

[0031] The mounting platform 1 is a cylindrical structure, and a short shaft 11 is arranged at one end of the mounting platform 1. The short shaft 11 is a cylindrical structure and is fixedly connected to the mounting platform 1. The short shaft 11 is clamped by using a triangular chuck of an external lathe, so that the mounting platform 1 is connected to the external lathe. A mounting plane 15 is arranged on the mounting platform 1 away from the short shaft 11. The mounting plane 15 is parallel to the short shaft 11 on the mounting platform 1, that is, the quadrilateral section in the mounting platform 1 is the mounting plane, so that the four-way joint 4 to be processed can be After being placed stably and in a horizontal state, a groove 12 is provided on the installation plane 15, and the groove 12 is used to limit the four-way joint 4 to be processed, so as to ensure that the four-way joint 4 to be processed will not shake in the groove 12 during processing and ensure that the reference line of the part during processing remains unchanged. A mounting hole 13 is provided in the groove 12 and vertically penetrates the installation platform 1. The mounting hole 13 is provided at the center of the groove 12, and the center of the internal through hole of the four-way joint 4 to be processed is aligned with the mounting hole 13 to determine the center distance of the four-way joint 4 to be processed.

[0032] The positioning shaft 2 is inserted into the mounting hole 13, and the top of the positioning shaft 2 is sleeved with the four-way joint 4 to be processed. The two ends of the positioning shaft 2 extend out of the top of the four-way joint 4 to be processed and the bottom of the mounting platform 1, respectively. The positioning shaft 2 is used to pass through the center of the four-way joint 4 to be processed and limit it, so as to fix the four-way joint 4 to be processed, thereby preventing it from being offset during processing. The diameter of the positioning shaft 2 matches the opening size of the mounting hole 13, so that the positioning shaft 2 will not shake excessively when inserted into the mounting hole 13 and can ensure that the positioning shaft 2 passes through the through hole of the four-way joint 4 to be processed.

[0033] Furthermore, the length of the positioning shaft 2 is greater than the sum of the depth of the mounting hole 13 and the height of the four-way joint 4 to be processed, so as to ensure that the positioning shaft 2 has sufficient length to limit the four-way joint 4 to be processed after being inserted into the mounting hole 13.

[0034] The two fastening components 3 are respectively arranged at the two ends of the positioning shaft 2, and the two fastening components 3 are both threadedly connected to the positioning shaft 2, one of the fastening components 3 is abutted against the top end of the four-way joint 4 to be processed, and the other fastening component 3 is abutted against the bottom end of the mounting platform 1, and the fastening component 3 is used to cooperate with the positioning shaft 2 to limit the four-way joint 4 to be processed, and the fastening component 3 is used to further fix the four-way joint 4 to be processed on the mounting platform 1 and can be quickly disassembled. In this embodiment, the staff fixes the mounting platform 1 on the external lathe through the short shaft 11, and then places the four-way joint 4 to be processed in the groove 12 on the mounting platform 1. After finding the reference line and determining the center distance, the positioning shaft 2 is inserted into the mounting hole 13 and the four-way joint 4 to be processed, and then the four-way joint 4 to be processed is fixed in the groove 12 through the fastening component 3, so that the four-way joint 4 to be processed can be quickly clamped and stopped, ensuring that its reference line and center distance will not be offset during processing. That is, the disadvantage of low overall processing efficiency caused by product clamping error in the prior art is effectively solved.

[0035] In a preferred embodiment, one end of the groove 12 is located at the edge of the mounting platform 1 and is provided with a groove 121 for taking the four-way joint 4 to be processed. The groove 121 is arranged on the other end plane of the working platform away from the short axis 11, so as to reduce the probability of damage caused by collision with the groove 12 when the staff takes the four-way joint 4 to be processed.

[0036] In a preferred embodiment, a cleaning groove 14 is also provided on the mounting platform 1, and the cleaning groove 14 is connected to the end of the groove 12 away from the groove 121. The cleaning groove 14 is a through groove parallel to the groove 121 and runs through the mounting platform 1, and is used to collect and clean the iron filings after processing, so that after processing a group of parts, the iron filings can be easily removed by a brush or an air gun, thereby preventing the iron filings remaining in the groove 12 from causing inaccurate baselines of the four-way joint 4 to be processed.

[0037] In a preferred embodiment, the groove 12 is adapted to the four-way joint 4 to be processed, that is, the shape of the groove is adapted to the contact surface shape of the four-way joint 4 to be processed, that is, when the four-way joint 4 to be processed is placed on the mounting plane 15 of the mounting platform 1, the mounting platform 1 uses the shape of the groove 12 to limit the entire four-way joint 4 to be processed (such as setting the corresponding groove shape according to the bottom end shape of the four-way joint 4 to be processed). In addition, during multi-directional processing, gaskets can be used to pad the groove 12 according to the difference in center heights of the four-way joint 4 to be processed to solve the clamping problem of multi-directional joints.

[0038] In a preferred embodiment, the installation platform 1 is an integrally formed structure, so that iron filings are not easily entered into the installation platform 1, thereby ensuring a long service life thereof.

[0039] In this embodiment, threads are provided at both ends of the positioning shaft 2. To facilitate the overall description of the two fastening components 3, one fastening component 3 is used as an example. Specifically, one fastening component 3 includes a nut 31 and a washer 32. The washer 32 is sleeved on the outside of the positioning shaft 2 and abuts against the top end of the four-way joint 4 to be processed. The nut 31 is threadedly connected to the top end of the positioning shaft 2 extending from the four-way joint 4 to be processed, and the bottom end of the nut 31 abuts against the top end of the washer 32. The fastening component 3 at the lower end of the mounting platform 1 adopts the same installation method as the above steps. The washer 32 is sleeved on the outside of the positioning shaft 2 and abuts against the bottom end of the mounting platform 1. The nut 31 is threadedly connected to the bottom end of the positioning shaft 2 extending from the mounting platform 1, and the top end of the nut 31 abuts against the bottom end of the washer 32. In this embodiment, the nut 31 cooperates with the thread on the positioning shaft 2 so that the four-way joint 4 to be processed is firmly abutted in the groove 12, and the washer 32 is used to fill the gap between the nut 31 and the mounting platform 1 and the four-way joint 4 to be processed to prevent the nut 31 from loosening, and at the same time can disperse the pressure of the nut 31 on the mounting platform 1 and the four-way joint 4 to be processed to prevent damage to parts. In a preferred embodiment, in order to increase the service life of the washer 32, the washer 32 is made of aluminum material.
