Description

Technical Field

[0001] This utility model relates to the field of garage door motor technology, and in particular to a brazing bracket for a brazing furnace. Background Technology

[0002] A brazing furnace is a device used for brazing and bright heat treatment of metals. It is suitable for the mass production of small and medium-sized stainless steel parts (tableware, knives, hardware, etc.), such as bright quenching and tempering of martensitic stainless steel and bright annealing of austenitic stainless steel. In the brazing process, a mold is used to connect two or more workpieces to be brazed together; then the workpieces and the mold are placed together on a brazing support, which is then transported to the brazing furnace; the brazing furnace heats the workpieces to complete the brazing process; after the workpieces are brazed together, they are output from the brazing furnace together through the brazing support. Traditional brazing supports are mostly specialized and have relatively single use. In order to better place and support different processed workpieces, a brazing support for a brazing furnace is proposed.

[0003] As disclosed in the authorization announcement number CN222944670U, a brazing bracket for a brazing furnace includes a first telescopic rod and a base plate. Support plates are fixedly connected to the top of the crossbars on both the left and right sides, and to the front and rear sides. A first support rod is fixedly connected to the top of each support plate. A fixing plate is fixedly connected to the other end of each first support rod. A gripper is provided at the bottom of each fixing plate. A first screw is threaded to the top of the inner wall of each gripper. A first nut is threaded to the front side of each first screw. A cleaning mechanism is provided on the rear side of the top of the base plate.

[0004] Although it achieves the goal of drawing cleaning fluid from the water tank via a water pump and then delivering it to the rectangular nozzle through a water pipe to clean the workpiece, it also achieves automated cleaning by using an electric motor to drive the lead screw and nut assembly to move the second support rod and the rectangular nozzle horizontally. This ensures cleanliness before and after welding and reduces the impact of impurities on weld quality.

[0005] However, it does not solve the problems that existing brazed brackets are not conducive to adjusting and adapting to clamp and fix materials of different shapes, nor to moving and blowing away dust on the surface of the bracket, and are not conducive to flexibly adjusting the height of use, thus affecting the convenience of use.

A support arm is disposed at the end of the adjusting arm away from the integrated block, a linkage shaft is disposed at the end of the support arm near the adjusting arm, and the support arm is movably connected to the adjusting arm through the linkage shaft, and the support arm is movably connected to the third telescopic rod.

[0012] Preferably, the base has an integrated frame at its top, a slide bar at the top of the base on one side of the integrated frame, and an air pump on the outside of the base.

[0013] Preferably, a lead screw is movably mounted inside the integrated frame, and a servo motor is provided on the side wall of the integrated frame, with the output end of the servo motor connected to the lead screw.

[0014] Preferably, the surface of the lead screw is provided with a threaded sleeve, and the threaded sleeve is threadedly connected to the lead screw. An air jet frame is provided on the side wall of the threaded sleeve, and the air jet frame is slidably connected to the slide rod.

[0015] Preferably, the top of the air pump is provided with a flexible hose, and the flexible hose is connected to the air jet frame.

[0016] Preferably, a PLC controller is provided on the side wall of the air pump, and the output terminal of the PLC controller is electrically connected to the servo motor and the input terminal of the air pump.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this brazing bracket not only enables adjustment and adaptation to clamp and fix materials of different shapes and to move and blow away dust on the surface of the rack, facilitating flexible adjustment of the usage height, but also improves the convenience of use. (1) Place the material on the placement rack, loosen the first locking pin to disengage the first telescopic rod from the first sleeve, move the first telescopic rod, and the first telescopic rod will drive the limiting ring, clamping arm and clamping block to move upward. After moving to the use position, tighten the first locking pin to fix the first telescopic rod to the first sleeve. At the same time, loosen the second locking pin to separate the clamping arm from the limiting ring. Move the clamping arm, and the clamping arm will drive the clamping block to move and contact the surface of the material. Then tighten the second locking pin to fix the clamping arm to the limiting ring. Under the combined action of multiple sets of clamping blocks, the material is clamped and fixed. If the material is irregularly shaped, different distances can be adjusted by moving different first telescopic rods and clamping arms to adapt to different fixing points of irregularly shaped materials. If the material is high, in order to avoid To prevent materials from touching the inner wall of the brazing furnace, loosen the third locking pin to separate the second telescopic rod from the second sleeve. Move the second telescopic rod inward, causing the adjusting arm to rotate around the hinge shaft. Loosen the fourth locking pin to separate the third telescopic rod from the third sleeve. Move the third telescopic rod inward, causing the support arm to rotate around the linkage shaft, thereby lowering the height of the placement rack. Then tighten the third and fourth locking pins to fix the third telescopic rod to the third sleeve and the second telescopic rod to the second sleeve. As the height of the placement rack decreases, the material on it also decreases, allowing materials of higher height to be pushed into the brazing furnace. This allows for adjustable and adaptable clamping and fixing of materials of different shapes, facilitating flexible adjustment of the rack's operating height and improving ease of use.

[0018] (2) When the bracket comes out of the brazing furnace after use, it is placed above the base. The air pump pumps gas into the air jet frame through the flexible hose and sprays it onto the surface of the placement rack to clean the dust adhering to the surface of the placement rack. At the same time, the servo motor is turned on and the servo motor drives the lead screw to rotate. Under the threaded connection between the lead screw and the threaded sleeve, and the sliding cooperation between the air jet frame and the slide bar, the lead screw drives the air jet frame to move through the threaded sleeve. The air jet frame moves and blows air to clean the placement rack, which facilitates the comprehensive blowing and cleaning of the placement rack and improves the dust cleaning effect and convenience.
