Description

Technical Field

[0001] This invention relates to the field of metal welding and processing technology, specifically to a welding fixture for food mixing machine processing. Background Technology

[0002] Welding generally refers to the welding of metals. It is a forming method that uses heat or pressure, or both, to create interatomic bonding forces between two separate objects, thus joining them into a single unit. Classification: Based on the degree of heating and process characteristics, welding methods can be divided into three main categories: First, fusion welding, where the workpiece is locally heated to a molten state, forming a weld pool that cools and crystallizes to form a weld seam. The welded workpieces are then joined into an inseparable whole. Common fusion welding methods include gas welding, electric arc welding, electroslag welding, plasma arc welding, electron beam welding, and laser welding. Second, pressure welding, which requires pressure regardless of whether heating is used during the welding process. Common pressure welding methods include resistance welding, friction welding, cold pressure welding, diffusion welding, and explosive welding. Third, brazing, which uses a filler metal with a melting point lower than that of the metal being welded. After melting, the filler metal fills the joint gap and diffuses with the metal being welded to achieve a connection. During brazing, the workpiece does not melt and generally does not undergo plastic deformation.

[0003] Chinese patent CN116571910A discloses a metal processing welding device, relating to the field of metal welding, including a welding torch arc-shaped positioning frame with the opening facing downwards. A welding torch for welding processing is fixedly embedded in the top of the welding torch arc-shaped positioning frame. Metal round tubes are provided on both sides of the welding torch arc-shaped positioning frame. Two round tube supports distributed at a fixed distance are installed on the outside of each metal round tube, and the round tube supports and the welding torch arc-shaped positioning frame are concentrically fixed.

[0004] The metal casing welding equipment of this invention and the prior art are inconvenient to roll the weld edge when welding metal workpieces, and the weld edge is prone to lifting during welding. In the prior art, the simple pressing operation has a single pressure direction and lacks a good leveling effect. At the same time, metal welding generates a lot of fumes. In the prior art, most of them use suction equipment such as fans to suck up and collect the fumes and impurities generated during metal welding. However, the collected fumes are directly transported through pipes to downstream bag filters and other devices to separate the fumes and impurities from the air. It is inconvenient to separate the fumes and impurities during the process, resulting in high resistance of the bag filter, easy clogging, and reduced service life. At the same time, it increases the operating resistance of the fan and affects long-term dust removal operation.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on existing welding equipment. Summary of the Invention

[0006] The purpose of this invention is to provide a welding fixture for food mixing processing, which solves the problems mentioned in the background art regarding the inconvenience of reciprocating rolling of the welded edge and the inconvenience of settling and separating dust and impurities during the process.

[0019] Compared with the prior art, the present invention provides a welding fixture for food mixing machine processing, which has the following beneficial effects:

[0020] 1. This invention includes a shear tube with shear plates evenly distributed inside. On one hand, the shear plates divide the dust-laden air, increasing the contact area between the air and the plates. On the other hand, one end of each shear plate is designed with a downward-curving inclination, effectively allowing fine powder to settle onto it, thus reducing the powder content in the fluid passing through the shear tube, decreasing dust concentration, and reducing the pressure on subsequent filtration and collection. Simultaneously, the reverse rotation of the welding gun, driven by the ratchet assembly, allows the upper and lower shear tubes to switch positions via the mounting shaft and mounting plate. When the upper shear tube rotates to the lower position, a flipping assembly flips it, ensuring it is vertical when it reaches the top of the collection frame. Furthermore, a vibration assembly vibrates the shear tubes, effectively discharging dust and impurities into the collection frame for collection. This allows the two shear tubes to be used repeatedly without clogging. Switching and vibration operations are achieved simply by the reverse rotation of the welding gun, requiring no additional power.

[0021] 2. In this invention, a flattening assembly is provided below the mounting base. The rotation of the welding gun can drive the rotation of the auxiliary toothed roller through the main toothed roller, which, together with the contact head, realizes the reciprocating movement of the piston plate. In turn, the T-shaped rod can drive the flattening frame to reciprocate, and the flattening roller at its bottom can repeatedly roll the two sides of the welding area. On the one hand, the rolling method can flatten the area through rolling friction, reduce friction, and improve the flattening effect. At the same time, the reciprocating rolling can eliminate the rolling blind zone between adjacent flattening rollers, which can effectively prevent the welding area from lifting and improve the integrity of metal welding processing.

Connecting shafts 10 are rotatably mounted on the inner walls at both the upper and lower positions of the mounting plate 9, and a shear tube 11 is fixed to one end of each connecting shaft 10. A shear plate 111 is fixed inside the transformer tube 11. A gas collecting pipe 12 is attached to and passes through the outer end of the shear tube 11 above the mounting plate 9, and the gas collecting pipe 12 is mounted on the multi-axis frame 2. A collection frame 15 is provided at the bottom of the shear tube 11 below the mounting plate 9, and the collection frame 15 is fixed to the outside of the mounting base 3. A dust suction head 165 is installed on the top of the outside of the mounting base 3, and the dust suction head 165 passes through and is attached to the shear tube 11 above.

A vibration assembly 14 is provided on the inside of the mounting plate 9, and the vibration assembly 14 is used to vibrate the shear tube 11.

[0037] Regarding the specific structure of the shear tube 11, the shear plates 111 are evenly distributed inside the shear tube 11, and the outer ends of the shear plates 111 are designed to be downwardly arc-shaped. The flipping assembly 13 includes a bevel gear 131, which is sleeved on the connecting shaft 10. A bevel roller 132 meshes with the inner side of the connecting shaft 10, and the bevel roller 132 is rotatably mounted at a protruding position on the inner wall of the mounting plate 9. A rack 133 meshes with the flat gear at the inner end of the bevel roller 132, and the rack 133 is fixed to the outer side of the mounting base 3.

[0039] Example 2

[0040] For details regarding the structure of the flattening component 16, please refer to [link / reference]. Figures 1-5 and Figure 7A flattening assembly 16 is provided in the bottom cavity of the mounting base 3, and the flattening assembly 16 is used to flatten the welding area of ​​the metal plate. A driving assembly 18 is provided at the lower position of the mounting base 3, and the driving assembly 18 is used to drive the flattening assembly 16 to move. The flattening assembly 16 includes a second elastic telescopic rod 161, and the second elastic telescopic rod 161 is vertically fixed at the position of the horizontal bar in the bottom cavity of the mounting base 3.

A flattening frame 163 is located on the outer side of the bottom of the welding gun 5, and a dust suction head 165 is mounted on the inner wall of the flattening frame 163. The dust suction head 165 is connected to the fan 17 through a pipe and is located at the bottom edge of the welding gun 5. The flattening rollers 164 are evenly distributed within the flattening frame 163, and two sets of flattening rollers 164 are symmetrically arranged within the flattening frame 163. The drive assembly 18 includes a main toothed roller 181, which is fixed to the outer rod of the welding gun 5. A secondary toothed roller 182 meshes with the bottom of the main toothed roller 181. Both the auxiliary toothed roller 182 and the main toothed roller 181 are rotatably mounted on the outside of the mounting base 3. A first oil tank 183 is located below the auxiliary toothed roller 182 and is fixed to a protruding position on the outside of the mounting base 3. A piston plate 184 is installed inside the first oil tank 183, and a push rod 185 is fixed to the top of the piston plate 184. A fourth elastic telescopic rod 186 is fixed between the protruding middle portion of the push rod 185 and the top of the first oil tank 183. An abutment head 187 is located above the push rod 185 and is fixed to the shaft of the auxiliary toothed roller 182. The first oil tank 182... 3. A second oil tank 188 is connected via a hose, and the second oil tank 188 is fixed to the outside of the fifth elastic telescopic rod 1810. The fifth elastic telescopic rod 1810 is fixed at the position of the crossbar in the bottom cavity of the mounting base 3. A T-shaped rod 189 is provided inside the second oil tank 188, and one end of the T-shaped rod 189 extends out of the second oil tank 188 and is fixed to the outside of the flattening frame 163. The diameter of the auxiliary toothed roller 182 is larger than the diameter of the main toothed roller 181. The contact head 187 is designed as a hemispherical structure. The fifth elastic telescopic rod 1810 and the second elastic telescopic rod 161 are distributed on both sides of the flattening frame 163.

[0041] Note: By using the power of the welding gun 5 and the drive assembly 18, the flattening frame 163 inside the flattening assembly 16 can reciprocate, and the flattening roller 164 can roll the welding edge of the metal part to prevent it from lifting.

[0042] Working principle: When using this dust-free and environmentally friendly welding equipment for metal parts processing, such as Figures 1-10In the process, the metal part is first placed on the base 1. The multi-axis frame 2 drives the mounting base 3 to move, and the motor 4 is started. The motor 4 drives the welding gun 5 to rotate, and the telescopic cylinder mounted on the top of the welding gun 5 performs the welding operation on the metal part. At the same time, the flattening roller 164 at the bottom of the flattening frame 163 contacts the side of the metal part to be welded. As the welding depth increases, the flattening frame 163 can move vertically and elastically abut against the second elastic telescopic rod 161 and the fifth elastic telescopic rod 1810. The welding gun 5 drives the main toothed roller 181 to rotate, and the main toothed roller 181 drives the auxiliary toothed roller 182 to rotate. The abutment on the auxiliary toothed roller 182... Contact 187 contacts push rod 185, pushing push rod 185 and piston plate 184 downward. At the same time, in coordination with fourth elastic telescopic rod 186, push rod 185 and piston plate 184 can move up and down as auxiliary toothed roller 182 rotates continuously. The movement of piston plate 184 pushes oil in first oil tank 183 into second oil tank 188. Through T-shaped rod 189, it pushes flattening frame 163 to move laterally. In coordination with the use of third elastic telescopic rod 162, piston plate 184 can realize the lateral reciprocating movement of flattening frame 163 when reciprocating, and perform reciprocating rolling operation on the welding edge of metal parts.

[0043] During welding, the fan 17 is started. The fan 17 is connected to the dust suction head 165 through a pipe. The dust suction head 165 adsorbs the dust and impurities at the welding gun 5. A channel with a large inner diameter is set at the connection between the fan 17 and the shear tube 11, which reduces the air velocity entering the shear tube 11. The dusty air enters the shear tube 11 and the fine powder is settled by the shear plate 111. Then, it is transported to the filter equipment such as a bag filter through the air collection pipe 12 to keep the exhaust air clean. The filter equipment such as the bag filter installed at the rear end of the air collection pipe 12 adopts the conventional installation and use method, which will not be described in detail here. When welding is finished, the motor 4 drives the welding gun 5 to rotate in the reverse direction. At this time, under the action of the ratchet assembly 7, the mounting shaft 8 is driven to rotate through the mounting sleeve 6. The mounting shaft 8 drives the mounting plate 9 to rotate, so that the mounting plate 9 drives the shear tube 11 to rotate through the connecting shaft 10, so that the upper and lower shear tubes 11 switch positions. At the same time, the conical roller 1... The 32 moves to the rack 133 position and rotates, driving the connecting shaft 10 and the shear tube 11 to rotate through the bevel gear 131. This keeps the shear tube 11 in a vertical position before it reaches the top of the collection frame 15. Due to the different lengths of the left and right racks 133, the shear plate 111 inside the shear tube 11 rotates to the top and is in the initial position. Furthermore, the length of the rack 133 is designed so that when the upper shear tube 11 returns to the top, it rotates 360° to return to its original position. During the switching process, the connecting shaft 10 drives the guide plate 144 to rotate. The contact head 145 on the guide plate 144 intermittently contacts the vibrating rod 143. In conjunction with the first elastic telescopic rod 142, the vibrating rod 143 can move back and forth. The vibration generated by the intermittent contact between the vibrating rod 143 and the outside of the shear tube 11 causes the tiny powder inside the shear tube 11 to fall into the collection frame 15, improving the recycling effect of the shear tube 11.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
