[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Specific implementation method 1: Figure 1-10 As shown, this embodiment describes an aircraft assembly docking positioning device, including two groups of frames Ⅰ1 and multiple groups of frames Ⅱ2; the lower ends of the frames Ⅰ1 and Ⅱ2 are fixedly connected with support rods 3, a connecting device 5 is provided between the frames Ⅰ1 and Ⅱ2, and the upper and lower ends of the frames Ⅰ1 and Ⅱ2 are provided with clamps 4;

[0025] The frame I1 is set in a U shape, and multiple frames II2 are arranged between the two frames I1; there is a gap between the adjacent frames I1 and II2, so that the staff can pass through the gap between the frames I1 and II2, so that the staff can get closer to the workpiece, and then after the arms are unfolded, the coverage area is larger, so that the range of processing on the workpiece surface is larger when standing in this position.

[0026] The connecting device 5 includes a connecting rod 51 and a plurality of transmission rods 52; a plurality of transmission rods 52 are fixedly connected to one side of the connecting rod 51. The frame I1 and the frame II2 are connected by the connecting device 5, thereby preventing the frame I1 and the frame II2 from moving relative to each other.

[0027] The upper and lower ends of the frame Ⅰ1 and frame Ⅱ2 are provided with limit devices 11;

[0028] The limiting device 11 includes two limiting plates 111; the two limiting plates 111 are fixedly connected to the frame body Ⅰ1 or the frame body Ⅱ2, and a gap is left between the two limiting plates 111 for the clamp 4 to pass through; the limiting plates 111 are provided with a circular hole for the shaft rod 112 to pass through, the shaft rod 112 is slidably matched with the circular hole, and the outer circumferential surface of the shaft rod 112 is provided with a slideway 113 arranged along the direction of its central axis; the slideway 113 is provided with an elastic telescopic rod 114 slidably matched with it, and the side of the elastic telescopic rod 114 is fixedly connected to a spring 115, and the other end of the spring 115 is fixedly connected to a transmission block 118; the transmission block 118 is connected to the slide The channel 113 is interference fit, and the transmission block 118 is fixedly connected to the hole wall of the central connecting hole of the transmission gear 117; the part of the transmission gear 117 close to the frame Ⅰ1 and the frame Ⅱ2 passes through the through holes on the frame Ⅰ1 and the frame Ⅱ2, and is located in the cavity inside the frame Ⅰ1 and the frame Ⅱ2; the side surfaces of the frame Ⅰ1 and the frame Ⅱ2 are provided with a through hole 12 connected with the internal cavity of the frame Ⅰ1 and the frame Ⅱ2; the transmission rod 52 is slidably matched with the through hole 12, and the upper and lower ends of the transmission rod 52 are provided with tooth grooves 53 meshing with the corresponding transmission gear 117; a circular groove 116 is provided on the limit plate 111 close to the transmission gear 117.

[0029] The clamp 4 includes a mounting rod 41 and a connecting member 42; the mounting rod 41 is fixedly connected to the upper ends of both sides of the connecting member 42, and the limiting rods 43 are fixedly connected to the lower ends of both sides of the connecting member 42; the side of the connecting rod 51 is provided with a limiting hole 54 that is slidably matched with the limiting rod 43; the mounting rod 41 is provided with a hole that is slidably matched with the shaft rod 112. The limiting hole 54 cooperates with the limiting rod 43 to prevent relative movement between the clamps 4, so as to ensure the positioning effect of the workpiece.

[0030] The hole is a tapered groove 44, and a spiral groove 45 is provided on the inner wall of the tapered groove 44 to slide with the elastic telescopic rod 114. The elastic telescopic rod 114 rotates with the shaft 112, so that the pressure between the free end of the elastic telescopic rod 114 and the inner wall of the spiral groove 45 gradually increases, until the elastic telescopic rod 114 finally presses the corresponding mounting rod 41 against the surface of the corresponding frame body Ⅰ1 and frame body Ⅱ2, so as to prevent the relative movement of the limiting rod 43 and the limiting hole 54 due to the processing error of the limiting rod 43 and the limiting hole 54, and the vibration generated when processing the workpiece will cause the two clamps 4 to move relative to each other, resulting in a poor fixation effect of the workpiece. Therefore, the cooperation between the elastic telescopic rod 114 and the spiral groove 45 can further ensure the positioning effect of the workpiece.

[0031] The inner diameter of one end of the tapered groove 44 close to the groove 116 is larger than the inner diameter of the other end of the tapered groove 44 away from the groove 116 .

[0032] The connecting rod 51 is located on the inner side of the frame body Ⅰ1 and the frame body Ⅱ2.

[0033] When the elastic telescopic rod 114 is located inside the groove 116 , the spring 115 is in a compressed state.

[0034] A method for using an aircraft assembly docking positioning device, the method comprising the following steps:

[0035] Step 1: Install the frame Ⅰ1 and the frame Ⅱ2 together through the connecting device 5;

[0036] Step 2: Install a portion of the clamp 4 on the limiting device 11 at the lower end of the frame Ⅰ1 and the frame Ⅱ2;

[0037] Step 3: Place the workpiece on the upper end of the fixture 4;

[0038] Step 4: Install another part of the clamp 4 on the limiting device 11 at the upper end of the frame Ⅰ1 and the frame Ⅱ2;

[0039] Step 5: Push the connecting rod 51 until the connecting rod 51 contacts the outer wall of the connecting member 42, so that the worker can pass through the gap between the frame body Ⅰ1 and the frame body Ⅱ2 and get closer to the workpiece.

[0040] The working principle of the present invention is: when using the device, the frame I1 and the frame II2 are placed on the ground according to the installation position, and then the connecting rod 51 and the transmission rod 52 are moved to the inner side of the frame I1 and the frame II2, and the transmission rod 52 is inserted into the corresponding through holes 12 on the frame I1 and the frame II2, so that the frame I and the frame II2 cannot move in the setting direction of the connecting rod 51;

[0041] Then, the corresponding clamp 4 is installed on the limiting device 11 at the lower end of the frame body Ⅰ1 and the frame body Ⅱ2. During the installation process, the shaft rod 112 is pulled in the direction of the transmission gear 117, so that the distal ends of the elastic telescopic rod 114 and the shaft rod 112 are both located in the groove 116, and then the installation rod 41 is inserted between the two limiting plates 111, and then the shaft rod 112 is pushed to make the shaft rod 112 pass through the tapered hole 44 and the limiting plate 111 away from the transmission gear 117;

[0042] Then place the workpiece on the upper end of the installed fixture 4, and finally install the corresponding fixture 4 of the other part on the limit device 11 at the upper end of the frame body Ⅰ1 and the frame body Ⅱ2 in the above manner, and then push the connecting devices 5 on both sides toward each other, so that the two connecting devices 5 move in the direction of the workpiece, until the limit hole 54 on the side of the connecting rod 51 on the connecting device 5 is sleeved on the limit rod 43 at the lower end of the side of the connecting piece 42, thereby limiting the up and down movement of the fixture 4 to prevent the fixing effect from deteriorating. At the same time, in the process of the connecting device 5 moving toward each other, the connecting rod 51 also drives the transmission rod 52 to move. The transmission rod 52 is provided with a tooth groove 53 and meshes with the corresponding transmission gear 117. Therefore, in the process of the transmission rod 52 moving, the transmission gear 117 is also driven to rotate. The transmission gear 117 drives the shaft rod 112 to rotate through the transmission block 118, and the shaft rod 112 drives the elastic telescopic rod 114 to rotate around the shaft rod 112 through the slide 113. Since the elastic telescopic rod 114 is located inside the groove 116, the spring 115 The elastic telescopic rod 114 is in a compressed state. Therefore, when the elastic telescopic rod 114 rotates around the shaft 112 to the entrance of the spiral groove 45, the elastic force of the spring 115 causes the elastic telescopic rod 114 to slide into the spiral groove 45. In the subsequent rotation of the shaft 112, the free end of the elastic telescopic rod 114 slides in the spiral groove 45. Since the hole is a conical groove 44, the length of the elastic telescopic rod 114 gradually shortens with the rotation of the shaft 112, and the pressure between the free end of the elastic telescopic rod 114 and the inner wall of the spiral groove 45 gradually increases. After the limiting hole 54 is sleeved on the limiting rod 43, the free ends of the elastic telescopic rods 114 corresponding in the two vertical directions are arranged relatively, so that the elastic telescopic rod 114 presses the mounting rod 41 tightly against the frame body Ⅰ1 and the frame body Ⅱ2 to prevent the limiting hole 54 and the limiting rod 43 from having a relatively movable space due to the processing error, resulting in the vibration generated during the assembly of the workpiece causing the clamp 4 to vibrate together, thereby affecting the fixing effect of the workpiece;

[0043] Since there is a gap between the adjacent frames Ⅰ1 and Ⅱ2, and the connecting rod 51 moves to abut against the connecting piece 42 during the process of fixing the workpiece, the worker can pass through the gap between the frames Ⅰ1 and Ⅱ2 and work closer to the workpiece, so that the area covered by his arms after unfolding is larger on the workpiece, which is more conducive to operation and reduces position movement.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other forms of assembly without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
