Description
Technical Field
[0001] This utility model belongs to the field of vacuum welding furnace technology, specifically relating to a material transfer device for a continuous vacuum welding furnace. Background Technology
[0002] Vacuum welding furnaces perform high-quality welding on products in a vacuum environment. During the heating or cooling process, N2 is introduced to protect the products and solder from oxidation. At the same time, the furnace is in a vacuum state and is not connected to the outside world, which reduces the oxidation reaction on the surface of the products and solder, thereby improving the surface quality of the weld and reducing the porosity of the weld. Continuous vacuum welding furnaces require the materials to be welded to be continuously transported to the welding station inside the furnace for welding.
[0003] Current material conveying structures within vacuum welding furnaces cannot reciprocate the conveying of workpieces to be welded, reducing welding efficiency. Furthermore, they cannot hoist and fix workpieces of different specifications, failing to meet the stability requirements for conveying workpieces of different specifications. Therefore, we propose a continuous material transfer device for vacuum welding furnaces. Utility Model Content

[0023] 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.
[0024] Please see Figures 1-2 This utility model provides a technical solution: a material transfer device for a continuous vacuum welding furnace, including a reciprocating transfer mechanism 1;
[0025] The reciprocating transfer mechanism 1 includes a first support and a second support symmetrically fixed inside the vacuum welding furnace body 4. Specifically, the front sealing door 3 and the rear sealing door 6 are respectively hinged to both sides of the vacuum welding furnace body 4 to facilitate the loading and unloading of the workpiece to be welded. A first drive sprocket 11 is rotatably arranged inside the first support, and a second drive sprocket 15 is rotatably arranged inside the second support. The first drive sprocket 11 is connected to a first driven sprocket 14 through a first transmission chain 13. The first driven sprocket 14 is rotatably arranged on the other side inside the first support. The second drive sprocket 15 is connected to a second driven sprocket 17 through a second transmission chain 16. The second driven sprocket 17 is rotatably arranged on the other side inside the second support. Six sets of crossbars 12 are evenly arranged between the first transmission chain 13 and the second transmission chain 16. A locking mechanism 2 is also provided on the crossbars 12.
[0026] The first drive sprocket 11 and the second drive sprocket 15 are respectively connected to the output shaft of their corresponding drive motors 5. The drive motors 5 are located on both sides of the vacuum welding furnace body 4 and can simultaneously drive the first drive sprocket 11 and the second drive sprocket 15 to rotate synchronously in the same direction.
[0027] First, the workpiece to be welded is fixed in the locking mechanism 2 on each crossbeam 12. Then, the first drive sprocket 11 and the second drive sprocket 15 are driven to rotate synchronously and in the same direction by two sets of drive motors 5. The first drive sprocket 11 and the second drive sprocket 15 are driven by the first driven sprocket 14 and the second driven sprocket 17, which can drive the first transmission chain 13 and the second transmission chain 16 to move synchronously. The synchronous movement of the first transmission chain 13 and the second transmission chain 16 drives the crossbeam 12 to move. The movement of the crossbeam 12 drives the workpiece to be welded to be continuously conveyed, so that the workpiece to be welded is moved to the welding station for welding.
[0028] Please see Figures 3-5 The locking mechanism 2 includes a first upright 21 and a second upright 24. The first upright 21 and the second upright 24 are respectively set at the bottom of the horizontal frame 12. The horizontal frame 12 is also provided with a bidirectional transmission component that controls the opposing movement of the first upright 21 and the second upright 24. The bottom of the first upright 21 is fixed with a first clamping seat 22, and the second upright 24 is fixed with a second clamping seat 23 on one side, which can clamp and fix the workpieces to be welded of different specifications. The first clamping seat 22 is fixed with a hanging rod 25 on one side, and one end of the hanging rod 25 is movably set in the positioning port 26. The positioning port 26 is set in the middle of the second clamping seat 23, which can suspend and fix the workpieces to be welded of different specifications.
[0029] The bidirectional transmission assembly includes a bidirectional ball screw 121, which is rotatably mounted in a mounting groove 122 located at the bottom of the crossbeam 12. A first screw nut 123 and a second screw nut 124 are symmetrically arranged on both sides of the bidirectional ball screw 121. The first screw nut 123 is connected to the first upright 21, and the second screw nut 124 is connected to the second upright 24, enabling control of the opposing movement of the first screw nut 123 and the second screw nut 124.
[0030] When fixing the workpiece to be welded, the workpiece is first suspended on the hanging rod 25. Then, the bidirectional screw is rotated to drive the first screw nut 123 and the second screw nut 124 to move in opposite directions. The first screw nut 123 and the second screw nut 124 drive the first upright 21 and the second upright 24 to move in opposite directions. The first upright 21 and the second upright 24 simultaneously drive the first clamping seat 22 and the second clamping seat 23 to move in opposite directions. The first clamping seat 22 drives the hanging rod 25 to move and moves the hanging rod 25 within the positioning port 26. When the first clamping seat 22 and the second clamping seat 23 are in contact with both sides of the workpiece to be welded, the first clamping seat 22 and the second clamping seat 23 clamp and fix the workpiece to be welded. This method can clamp workpieces of different specifications.
[0031] As a specific embodiment of this application, a driven bevel gear 127 is also provided on one side of the bidirectional ball screw 121. The driven bevel gear 127 meshes with the driving bevel gear 126. The driving bevel gear 126 is provided at one end of the knob 125. The knob 125 is rotated on one side of the top of the crossbeam 12, which can control the rotation direction of the bidirectional ball screw 121.
[0032] The knob 125 drives the active bevel gear 126 to rotate, which in turn drives the driven bevel gear 127 to rotate. The driven bevel gear 127 then drives the bidirectional ball screw 121 to rotate. By controlling the rotation direction of the bidirectional ball screw 121, the clamping and releasing operations of the first clamping seat 22 and the second clamping seat 23 can be controlled, thereby enabling rapid loading and unloading of workpieces.
[0033] Furthermore, a guide groove 128 is provided on one side of the mounting groove 122. Two sets of guide sliders are slidably arranged in the guide groove 128. The guide sliders are fixedly connected to the first wire nut 123 and the second wire nut 124 respectively. The first wire nut 123 and the second wire nut 124 drive the guide sliders to move in the guide groove 128, thereby improving the guiding performance of the first wire nut 123 and the second wire nut 124 when they move.
[0034] 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.
