Description

Technical Field

[0001] This application relates to the field of fin installation, and in particular to a mechanical device for installing fins. Background Art

[0002] The traditional positioning method is to make a mold, install the fins on the mold, and sleeve them on the upright post in a stacked form (analogous to a CD case). The holes in the fins correspond to four upright posts passing through. However, once the product specifications change, a new mold is required, resulting in high production costs. The welding process is inconvenient and the welding is uneven, easily causing the problem of mold jamming. To improve the solution, after welding the first fin, spacers with the unit thickness required for production are padded according to the spacing. However, this production method is inefficient.

[0003] The invention patent with the publication number CN113669919A discloses a method for installing finned heat pipes. Symmetrically arranged rib portions are provided in the fins along the diameter direction to connect the outer wing portions and the middle mounting portions. The feature is that an installation force application portion deviating from the diameter direction is provided on the rib portion. When installing the fin, first press the installation force application portion to compress the rib portion inward, so that the wing portions are in an inward extrusion state, then the fin is inserted into the inner sleeve of the heat pipe, and then the installation force application portion is released, and the rib portion provides elastic force to press the wing portions against the inner side wall of the inner sleeve of the heat pipe.

[0004] This fin installation method requires the operator to manually place the fin at the target location and press the force application portion with force. However, relying on manual operation by the operator not only has the problem of low accuracy but also is relatively inconvenient to operate. Utility Model Content

[0005] In order to facilitate welding the fins to the flange, this application provides a mechanical device for installing fins.

[0006] The mechanical device for installing fins provided by this application adopts the following technical solution:

[0007] A mechanical device for installing fins includes a workbench. A vertical first sliding rod and a fixing mechanism for fixing the flange are provided at the upper end of the workbench. A robotic arm is slidably connected to the first sliding rod in the vertical direction. A clamping mechanism and a welding torch are provided on the robotic arm. A driving member for driving the robotic arm to move is provided on the workbench. A loading tray for placing the fins is provided on the workbench.

[0008] By adopting the above technical solution, after the operator places the flange on the fixing mechanism, the robotic arm clamps the fins on the loading tray through the clamping mechanism, the driving member transports the robotic arm to a suitable position, the robotic arm places the fins on the flange, and the welding torch is used to weld the fins and the flange. By transporting and positioning the fins through the driving member and the robotic arm, compared with the traditional method of sleeving gaskets on the flange to position the fins, the operation is more convenient.

[0009] Optionally, the driving member includes a stepping motor, a first sliding block, and a lead screw. A vertical first sliding groove is formed on the first sliding rod. The first sliding block is slidably connected to the first sliding groove in the vertical direction. The lead screw is rotatably connected to the first sliding groove in the vertical direction and is in threaded cooperation with the first sliding block. The transmission shaft of the stepping motor is coaxially connected to the lead screw.

[0010] By adopting the above technical solution, the stepping motor drives the lead screw to rotate. When the lead screw rotates, it drives the first sliding block to move up and down along the first sliding groove. Compared with ordinary motors, the stepping motor has higher precision, making the positioning of the robotic arm more accurate.

[0011] Optionally, the clamping mechanism includes a telescopic rod, a first clamping rod, and a second clamping rod. One end of the first clamping rod and the first clamping rod are both rotatably connected to the robotic arm. The two ends of the telescopic rod are respectively connected to the first clamping rod and the second clamping rod and are used to drive the first clamping rod and the second clamping rod to approach or separate from each other.

[0012] By adopting the above technical solution, when the telescopic rod extends or contracts, it drives the first clamping rod and the second clamping rod to separate from or approach each other, thereby completing the clamping or releasing of the fins.

[0013] Optionally, guide plates are provided on the mutually approaching surfaces of the first clamping rod and the second clamping rod. The upper ends of the guide plates are arranged in an inclined plane, and the thicknesses of the two guide plates gradually become thinner in the mutually approaching direction.

[0014] By adopting the above technical solution, when clamping the fins, the first clamping rod and the second clamping rod drive the guide plates to move towards the fins. The inclined plane at the upper end of the guide plate is convenient for inserting into the gaps between the fins, playing a role in facilitating the clamping of the fins.

[0015] Optionally, the telescopic rod includes an installation cylinder, a first cylinder, and a second cylinder. The installation cylinder is arranged on the robotic arm. The first cylinder and the second cylinder are coaxially arranged at both ends of the robotic arm respectively. The piston rod of the first cylinder is connected to the first clamping rod, and the piston rod of the second cylinder is connected to the second clamping rod.

[0016] By adopting the above technical solution, the first cylinder is used to drive the first clamping rod to move, the second cylinder is used to drive the second clamping rod to move, and the mounting cylinder is used to fix the first cylinder and the second cylinder. Driving the first clamping rod and the second clamping rod through the cylinder is more stable.

[0017] Optionally, on the surfaces of the first clamping rod and the second clamping rod that are close to each other, second sliding grooves are provided. Second sliding blocks are slidably connected in the second sliding grooves along the length direction of the second sliding grooves. The two second sliding blocks are respectively rotatably connected to the piston rods of the first cylinder and the second cylinder.

[0018] By adopting the above technical solution, the first cylinder and the second cylinder respectively drive the two sliding blocks to move along the second sliding groove. When the two sliding blocks move, they drive the first clamping rod and the second clamping rod to approach or separate. The transmission of the sliding blocks and the second sliding grooves reduces the occurrence of jamming.

[0019] Optionally, limiting strips are provided on the inner side walls of the second sliding grooves, and limiting grooves for limiting with the limiting strips are provided on the side walls of the second sliding blocks.

[0020] By adopting the above technical solution, the limiting strips are engaged with the limiting grooves on the second sliding blocks, reducing the occurrence of the second sliding blocks sliding out.

[0021] Optionally, a horizontal fixing rod is provided on the robotic arm. A fixing ring is provided at the end of the fixing rod away from the robotic arm. The fixing ring is sleeved on the mounting cylinder.

[0022] By adopting the above technical solution, the mounting cylinder is fixedly connected to the robotic arm through the fixing rod and the fixing ring, and the connection is more stable.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The robotic arm clamps the fins on the loading tray through the clamping mechanism, and the driving member transports the robotic arm to a suitable position. The robotic arm places the fins on the flange. The welding torch is used to weld the fins and the flange.

Detailed implementation manners

[0033] The following further elaborates on the present application in conjunction with the attached Figures 1-5 to make a more detailed description of the present application.

[0034] An embodiment of the present application discloses a mechanical device for installing fins. Referring to Figure 1 , a mechanical device for installing fins includes a horizontal workbench 1, on the upper end of which are installed a fixing mechanism 11 for fixing flanges, a vertically upward first sliding rod 13, and a loading tray 12 for placing fins.

[0035] Referring to Figure 1 , Figure 2 and Figure 3, a driving member 3 is installed on the first sliding rod 13. The driving member 3 includes a stepping motor 31, a first sliding block 32 and a lead screw 33. A vertical first sliding groove 34 is formed on the first sliding rod 13. The first sliding block 32 is slidably connected to the first sliding groove 34 in the vertical direction. The lead screw 33 is rotatably connected to the first sliding groove 34 in the vertical direction. The first sliding block 32 is sleeved on the lead screw 33 and is in threaded cooperation with the lead screw 33. The stepping motor 31 is installed on the workbench 1, and the transmission shaft of the stepping motor 31 is coaxially connected to the lead screw 33. The stepping motor 31 drives the lead screw 33 to rotate. When the lead screw 33 rotates, it drives the first sliding block 32 to move up and down.

[0036] Refer to Figure 1 , Figure 4 and Figure 5 , a robotic arm 2 is installed on the first sliding block 32. A clamping mechanism 4 for clamping fins and a welding torch 21 for welding the fins to the flange are installed on the robotic arm 2. The clamping mechanism 4 includes a telescopic rod 43, a first clamping rod 41 and a second clamping rod 42. Two horizontal fixing rods 7 are fixedly connected to the robotic arm 2. A fixing ring 8 is fixed at the end of the fixing rod 7 away from the robotic arm 2. The fixing ring 8 is sleeved on the telescopic rod 43 to fix the telescopic rod 43. The first clamping rod 41 and the second clamping rod 42 are both rotatably connected to the robotic arm 2. The first clamping rod 41 and the second clamping rod 42 are respectively located at both ends of the telescopic rod 43 in the length direction. The telescopic rod 43 is used to drive the first clamping rod 41 and the second clamping rod 42 to approach or separate from each other. Horizontal guide plates 5 are installed on the mutually approaching surfaces of the first clamping rod 41 and the second clamping rod 42. The upper ends of the two guide plates 5 are arranged in an inclined plane, and the thicknesses of the two guide plates 5 gradually become thinner in the mutually approaching direction, so as to facilitate insertion into the gap between the fins and play a role in facilitating the clamping of the fins.

[0037] Refer to Figure 1 , Figure 4 and Figure 5, the telescopic rod 43 includes a mounting cylinder 431, a first cylinder 432 and a second cylinder 433. The fixing ring 8 is sleeved on the mounting cylinder 431. The first cylinder 432 and the second cylinder 433 are respectively coaxially arranged at both ends of the robotic arm 2. Second sliding grooves 61 are formed on the mutually approaching surfaces of the first clamping rod 41 and the second clamping rod 42. Second sliding blocks 62 are slidably connected in the second sliding grooves 61 along the length direction of the second sliding grooves 61. The two second sliding blocks 62 are respectively rotatably connected to the piston rods of the first cylinder 432 and the second cylinder 433. The first cylinder 432 and the second cylinder 433 respectively drive the two sliding blocks to move along the second sliding grooves 61. When the two second sliding blocks 62 move, they drive the first clamping rod 41 and the second clamping rod 42 to approach or separate. The transmission of the second sliding blocks 62 and the second sliding grooves 61 reduces the occurrence of jamming. A limiting strip 63 arranged along the length direction of the second sliding groove 61 is fixed on the inner side wall of the second sliding groove 61. A limiting groove 654 for engaging with the limiting strip 63 is formed on the second sliding block 62. The engagement of the limiting strip 63 and the limiting groove 654 reduces the sliding out of the second sliding block 62.

[0038] The implementation principle of a mechanical device for installing fins in an embodiment of this application is as follows: After an operator fixes the flange on the fixing mechanism 11, the stepping motor 31 conveys the robotic arm 2 to the feeding tray 12 through the transmission of the lead screw 33 and the first sliding block 32. The first cylinder 432 and the second cylinder 433 drive the two second sliding blocks 62 to move away from each other, causing the first clamping rod 41 and the second clamping rod 42 to separate. After the first clamping rod 41 and the second clamping rod 42 are located on both sides of the fin, the first cylinder 432 and the second cylinder 433 drive the two second sliding blocks 62 to approach each other, causing the first clamping rod 41 and the second clamping rod 42 to clamp the fin. The stepping motor 31 conveys the robotic arm 2 to the flange through the transmission of the lead screw 33 and the first sliding block 32. After the fin is conveyed to the designated position, the welding torch 21 welds the fin to the flange. By driving the fin to move with the stepping motor 31, the positioning of the fin is more accurate, reducing the welding error.

[0039] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
