To address this, we propose a deformation-resistant support fixture for reactor desoldering. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 The present invention provides a reactor desoldering soldering anti-deformation support fixture, comprising a base plate 1, a support plate 2, a guide moving assembly 3, a drive linkage assembly 4, and a flexible clamping assembly 5. The base plate 1 serves as the installation foundation for the entire fixture and is made of high-strength alloy steel plate to ensure the stability of the overall structure of the fixture. A support plate 2 for placing the reactor is fixedly installed on the upper surface of the base plate 1. The support plate 2 is connected to the base plate 1 by bolts for easy disassembly and maintenance. Two guide moving components 3 are provided, symmetrically arranged on both sides of the bottom length of the base plate 1. Each guide moving component 3 includes a guide rail 301, a slider 302, and a moving plate 303. Two guide rails 301 are provided, extending along the length of the base plate 1 and symmetrically fixed on both sides of the bottom of the base plate 1. The guide rails 301 are connected to the base plate 1 by countersunk bolts to prevent the bolt heads from protruding and affecting the movement of the slider. The moving plate 303 is guided and slidably connected between the two guide rails 301 by the slider 302. The slider 302 and the guide rail 301 are in clearance fit to ensure that the moving plate 303 can slide smoothly along the guide rail 301. The drive linkage assembly 4 is located at the bottom of the base plate 1 and is used to drive the two guide moving assemblies 3 to move synchronously in opposite directions or in opposite directions. The drive linkage assembly 4 includes a drive cylinder 401, a central connecting rod 402, and an outer connecting rod 403. The drive cylinder 401 is fixed to the bottom of the base plate 1 by a cylinder bracket. The output end of the drive cylinder 401 is connected to one of the moving plates 303 through a floating joint to reduce the influence of installation errors on the cylinder action. The center position of the central connecting rod 402 is rotatably set at the center position of the bottom of the base plate 1 through a first bearing seat 404, which is welded and fixed to the base plate 1. There are two outer connecting rods 403. One end of the two outer connecting rods 403 is rotatably connected to both ends of the central connecting rod 402 through a pin, and the other end of the two outer connecting rods 403 is rotatably connected to the two moving plates 303 through a pin. The central connecting rod 402 and the two outer connecting rods 403 form a Z-shaped linkage structure. When the drive cylinder 401 extends or retracts, the two moving plates 303 can be driven to move synchronously in opposite directions through the Z-shaped linkage structure. Each guide moving assembly 3 has a flexible clamping assembly 5 at both ends, and the clamping end of the flexible clamping assembly 5 is higher than the upper surface of the support plate 2. The flexible clamping assemblies 5 on the two guide moving assemblies 3 cooperate to flexibly clamp and fix the reactor on the support plate 2. The flexible clamping assembly 5 includes a fixed frame 501, a second bearing seat 502, a rotating bracket 503, and clamping rollers 504. The fixed frame 501 is welded to the upper end of the moving plate 303 near the reactor and protrudes from the outside of the base plate 1 to ensure effective clamping of the reactor. The rotating bracket 503 is rotatably mounted on the fixed frame 501 through the second bearing seat 502 and is bolted to the fixed frame 501. The rotating bracket 503 is provided with at least two clamping rollers 504 to form a clamping structure on one side of the reactor. Furthermore, the rotating bracket 503 is an L-shaped bracket. The center of the rotating bracket 503 is rotatably connected to the fixed frame 501 through the second bearing seat 502. Both ends of the rotating bracket 503 are rotatably equipped with clamping rollers 504 through bearings. The outer side of the clamping rollers 504 is covered with a rubber sleeve. The rubber sleeve is made of wear-resistant elastic rubber, which can achieve flexible clamping and increase the friction with the surface of the reactor, thereby improving the clamping stability. A rubber pad 6 is provided on the support plate 2. The rubber pad 6 is attached to the upper surface of the support plate 2 with glue. The rubber pad 6 can buffer and protect the bottom of the reactor, and further prevent the bottom of the reactor from deforming due to hard contact.

[0017] The beneficial effects of this utility model are as follows: 1. Through the Z-shaped linkage structure of the drive linkage assembly 4, the two guide moving assemblies 3 can move synchronously towards or in opposite directions, ensuring that the clamping force of the flexible clamping assemblies 5 on both sides on the reactor is uniform, and avoiding deformation caused by uneven clamping force. 2. The flexible clamping component 5 adopts a structure of clamping roller 504 and rubber sleeve to achieve flexible clamping of the reactor. At the same time, the rotating bracket 503 can rotate around the second bearing seat 502, which can adapt to the shape of the reactor, reduce hard squeezing during the clamping process, and effectively prevent the reactor from deforming. 3. Flexible clamping components 5 are provided at both ends of each guide moving component 3 to form a multi-clamping point structure, which improves the firmness of the reactor clamping. At the same time, the rubber pad 6 on the support plate 2 plays a buffering and protective role on the bottom of the reactor, further ensuring the integrity of the reactor.

[0018] In summary, the method of using the anti-deformation support fixture for desoldering of reactors provided in this embodiment is as follows: During use, the reactor is placed on the rubber pad 6 of the support plate 2. The drive cylinder 401 is activated, and the piston rod of the drive cylinder 401 extends, pushing the connected moving plate 303 to move along the guide rail 301. The moving plate 303 drives the central connecting rod 402 to rotate around the first bearing seat 404 via the outer connecting rod 403. The other end of the central connecting rod 402 pulls another moving plate 303 to move synchronously in the opposite direction via the outer connecting rod 403, causing the two guide moving components 3 to move towards each other. This causes the flexible clamping component 5 to approach the reactor, and the rubber sleeve on the outside of the clamping roller 504 contacts the surface of the reactor. The rotating bracket 503 rotates around the second bearing seat 502 to adapt to the shape of the reactor, forming a stable flexible clamp. After welding is completed, the piston rod of the drive cylinder 401 retracts, causing the two guide moving components 3 to move in opposite directions. The flexible clamping component 5 releases the reactor, allowing the reactor to be removed.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
