Description

Technical Field

[0002] A coaxial connector refers to a part used to connect the ends of two shafts to ensure that the center lines of the two shafts are on the same axis. It is generally used to connect the driving shaft and the driven shaft to transmit the rotational motion of the driving shaft to the driven shaft. During the production process of the coaxial connector, the various components are connected together by welding. However, the various components passing through the connector are basically not of the same diameter, which makes welding troublesome and easily makes the two not on the same axis.

The positioning drive mechanism is installed on the outer side of the shell 4511 and is connected to the multiple positioning clamping rods 452 to drive the multiple positioning clamping rods 452 to move synchronously along the radial direction of the positioning ring 451.

[0050] In the above-mentioned coaxial connector welding positioning device, through the coordinated arrangement of the positioning ring 451, the positioning clamping rod 452 and the positioning drive mechanism, multiple positioning clamping rods 452 can be synchronously moved along the radial direction of the positioning ring 451, so that the coaxial connector body is clamped on the inner side of the main positioning mechanism 4, and its accessories are clamped on the inner side of the auxiliary positioning mechanism 5, thereby positioning and aligning the coaxial line of the coaxial connector body and its accessories.

[0051] Among them, regarding the positioning drive mechanism, specifically, the positioning drive mechanism includes a second drive motor 4510, a transmission gear assembly and a transmission telescopic component. The second drive motor 4510 is installed on the outside of the outer shell 4511, and the transmission telescopic component is installed between the positioning ring 451 and the positioning clamp rod 452, and is connected to the output end of the second drive motor 4510 through the transmission gear assembly.

[0052] Regarding the transmission telescopic component, more specifically, the transmission telescopic component includes a threaded sleeve 453, a limiting block 454 and a limiting square sleeve 455. The threaded sleeve 453 is rotatably installed on the outer wall of the positioning ring 451, and the limiting square sleeve 455 is fixed on the outer wall of the positioning ring 451.

[0054] The docking mechanism 3 is installed between the fixed seat 1 and the movable seat 2 to adjust the distance between the fixed seat 1 and the movable seat 2. Specifically, the docking mechanism 3 includes a driving motor 31, a docking screw 32, a threaded tube 33, a limiting slide rod 34 and a limiting sleeve 35. The driving motor 31 is fixed to the side end of the fixed seat 1, the docking screw 32 is coaxially fixed to the output end of the driving motor 31, the threaded tube 33 is fixed to the side end of the movable seat 2 and is threadedly sleeved on the outer side of the docking screw 32, the limiting slide rod 34 and the limiting sleeve 35 are respectively fixed to the ends of the fixed seat 1 and the movable seat 2 that are close to each other, and the limiting sleeve 35 is slidably sleeved on the outer side of the limiting slide rod 34.

[0055] A roller 201 is installed at the lower end of the movable seat 2 to reduce the resistance of the movable seat 2 when it moves horizontally.

[0056] The coaxial connector body and its accessories are brought close to each other through the docking mechanism 3, and the welding auxiliary mechanism 7 drives the main positioning mechanism 4 and the auxiliary positioning mechanism 5 to respectively drive the coaxial connector body and the accessories to rotate synchronously along their axes to achieve rapid welding, making the operation more convenient and reliable.

[0057] An L-shaped extension clamp rod 45201 is horizontally fixed to the end of the positioning clamp rod 452 located on the inner side of the positioning ring 451. The short side of the L-shaped extension clamp rod 45201 is arranged toward the axial direction close to the positioning ring 451, and a ball 45205 is movably installed thereon. The L-shaped extension clamp rod 45201 can meet the clamping requirements of accessories of different specifications, and the set ball 45205 can reduce the wear on the accessories during the process of taking and placing the accessories.

[0059] Working principle: First, the main positioning mechanism 4 and the auxiliary positioning mechanism 5 are used to fix the coaxial connector body and its accessories on the same axis. Specifically, the driving motor 2 4510 on the main positioning mechanism 4 and the auxiliary positioning mechanism 5 is used to drive one of the flat gears 1 458 to rotate, and the flat gear 1 458 drives all the flat gears 1 458 to rotate synchronously through the outer gear ring 1 459. The flat gear 1 458 rotates the threaded sleeve 453 through the reversing transmission action of the bevel gear 1 456 and the bevel gear 2 457. Under the sliding limit action of the limit block 454 and the limit square sleeve 455, the threaded sleeve 453 drives the positioning clamp rod 452 to move along the radial direction of the positioning ring 451 to clamp the coaxial connector body or its accessories, so as to realize the coaxial positioning and alignment of the coaxial connector body and its accessories;

[0060] By setting up the docking mechanism 3, the driving motor 31 is used to drive the docking screw 32 to rotate. Under the sliding and limiting action of the limiting slide rod 34 and the limiting sleeve 35, the docking screw 32 and the threaded tube 33 are contracted, so that the movable seat 2 is moved closer to the fixed seat 1, thereby making the coaxial connector body and its accessories close to each other, and welding operation can be carried out at this time; in addition, this design makes it easy to shrink the device as a whole, thereby facilitating storage.

[0061] Second implementation method:

[0062] This embodiment is based on the embodiment 1, and the following structure is added to enable the present application to have the effect of rapid welding, and the specific configuration is as follows: Figure 1-4 As shown, it also includes a welding auxiliary mechanism 7, which is installed between the fixed seat 1, the movable seat 2, the main positioning mechanism 4 and the auxiliary positioning mechanism 5 to drive the main positioning mechanism 4 and the auxiliary positioning mechanism 5 to rotate synchronously along their axes.

[0063] The fixing frame 6 includes a fixing column 61 and a mounting ring 62 . The mounting ring 62 is fixed to the upper ends of the fixing seat 1 and the movable seat 2 through the fixing column 61 . The housing 4511 is rotatably sleeved on the inner side of the mounting ring 62 .

[0064] Specifically, the welding auxiliary mechanism 7 includes a driving motor three 71, a flat gear two 72, an outer gear ring two 73, a limiting square rod 74 and a limiting square tube 75. The driving motor three 71 is fixed to the side end of the movable seat 2, and the output end of the driving motor three 71 is coaxially fixed with the flat gear two 72. The outer gear ring two 73 is fixedly sleeved on the outer side of the outer shell 4511 and meshed with the flat gear two 72. The limiting square rod 74 is coaxially fixed on the flat gear two 72. The limiting square tube 75 is coaxially fixed on the flat gear two 72 corresponding to the lower side of the main positioning mechanism 4, and the limiting square tube 75 is slidably sleeved on the outer side of the limiting square rod 74.

[0065] Through the setting of the welding auxiliary mechanism 7, the driving motor three 71 is used to drive the flat gear two 72 to rotate, and the flat gear two 72 drives the outer gear ring two 73 to rotate along its axis with the auxiliary positioning mechanism 5. Under the sliding limiting action of the limiting square tube 75 and the limiting square rod 74, the main positioning mechanism 4 rotates synchronously along its axis, so that the coaxial connector body and its accessories rotate synchronously, realizing rapid welding, and the operation is more convenient and reliable.

[0066] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
