Abstract
Description
Technical Field
[0001] The present application relates to the technical field of component welding, and in particular to a right-angle welding fixture for mechanical mold components. Background Art
[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure.
[0003] However, in actual applications, when performing direct welding operations on most existing mold parts, the two parts are usually manually aligned and corrected first, then spot welded for positioning, and finally welded as a whole. However, during the overall welding process, due to the influence of thermal expansion and contraction, the angle between the two parts is easily offset, which in turn leads to a decrease in welding quality and an increase in the defective rate, which is not conducive to promotion and use.
[0004] Therefore, those skilled in the art provide a right-angle welding fixture for mechanical mold parts to solve the problems raised in the above background technology. Utility Model Content
[0005] In order to solve the problem raised in the above background technology that during the overall welding process, due to the influence of thermal expansion and contraction, the angle between the two parts is easily offset, which in turn leads to a decrease in welding quality and an increase in the defective rate, which is not conducive to promotion and use, the present application provides a right-angle welding tool for mechanical mold parts.
[0006] The present application provides a right-angle welding tool for mechanical mold parts adopts the following technical solution: it includes a welding table, the top side of the welding table is fixedly connected to an L-shaped bending angle frame, the top side of the welding table is fixedly connected to a mounting block, the center of the mounting block is spirally connected to a spiral rod, the left end of the spiral rod is rotatably connected to an angle transmission plate, the angle transmission plate is slidably connected to the surface of the welding table, both ends of the angle transmission plate are fixedly connected to a pressure plate, and the two pressure plates are respectively parallel to the two side plates on the L-shaped bending angle frame.
[0007] Preferably, the top side of the welding platform is rotatably connected to two screw rods, and the outer sides of the two screw rods are threadedly connected to a U-shaped pressure rod.
[0008] Preferably, two guide holes are provided on the outer side of the mounting block, the inner walls of the two guide holes are slidably connected with guide rods, and the two guide rods are fixedly connected to the angle transmission plate.
[0009] Preferably, four limiting rods are fixedly connected to the top side of the L-shaped angle frame, and the four limiting rods are respectively slidably connected to the two U-shaped pressure rods.
[0010] Preferably, the top ends of the two screw rods are fixedly connected with a hexagonal transmission block.
[0011] In summary, this application has the following beneficial technical effects:
[0012] 1. By setting a pressure plate, the two parts to be welded are placed against the inner side of the L-shaped angle frame, and the two parts are in contact. The spiral rod is twisted, and the spiral rod gradually approaches the L-shaped angle frame as it rotates. The spiral rod drives the angle transmission plate gradually close to the L-shaped angle frame, and the angle transmission plate drives the pressure plate gradually close to the L-shaped angle frame. At this time, the pressure plate will squeeze the placed parts and make the parts and the L-shaped angle frame close together to form an extrusion fixation. At this time, when performing overall welding, the two parts can still be welded at right angles without the need for spot welding positioning, and the welding process will not be affected by thermal expansion and contraction to cause the angle to shift, effectively ensuring the welding quality and facilitating popularization and use.
[0013] 2. By setting up a U-shaped pressure rod, when the placed parts are squeezed and fixed, the screw is turned. When the screw rotates, it drives the U-shaped pressure rod to move downward to press and fix the parts from the top side, thereby further improving the stability of the right-angle welding of the parts and improving the welding quality.

At this time, the pressure plate 6 will squeeze the placed parts and make the parts and the L-shaped angle frame 2 fit tightly together to form an extrusion fixation. At this time, when the overall welding is performed, the two parts can still be welded at right angles without the need for spot welding positioning, and the welding process will not be affected by thermal expansion and contraction to cause the angle to shift, effectively ensuring the welding quality and being conducive to promotion and use.
[0020] In this application, the top side of the welding table 1 is rotatably connected to two screws 7, and the outer sides of the two screws 7 are threadedly connected to U-shaped pressure rods 8; by setting the U-shaped pressure rods 8, when the placed parts are squeezed and fixed, the screws 7 are turned, and when the screws 7 rotate, the U-shaped pressure rods 8 are driven to move downward to press and fix the parts from the top side, thereby further improving the stability of the right-angle welding of the parts and improving the welding quality.
[0021] In this application, two guide holes are opened on the outer side of the mounting block 3, and the inner walls of the two guide holes are slidably connected with guide rods 9, and the two guide rods 9 are fixedly connected to the angle transmission plate 5; by setting the guide holes and guide rods 9, when the angle transmission plate 5 moves, the guide holes and guide rods 9 cooperate with each other, so that the angle transmission plate 5 can maintain a straight line direction of movement to avoid deviation and affect the stability of subsequent extrusion fixation.
[0022] In the present application, four limit rods 10 are fixedly connected to the top side of the L-shaped bending angle frame 2, and the four limit rods 10 are respectively slidably connected to the two U-shaped pressure rods 8; by setting the limit rods 10, when the screw 7 rotates to drive the U-shaped pressure rod 8 to move downward, the limit rods 10 can be used to limit the U-shaped pressure rod 8 to prevent the U-shaped pressure rod 8 and the screw 7 from rotating.

[0024] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings.

At this time, when performing overall welding, the two parts can still be welded at right angles without the need for spot welding positioning, and the welding process will not be affected by thermal expansion and contraction to cause the angle to deviate, which is effective It ensures the welding quality and is conducive to promotion and use. After the placed parts are extruded and fixed, the screw rod 7 is turned. When the screw rod 7 rotates, it drives the U-shaped pressure rod 8 to move downward to press and fix the parts from the top side, thereby further improving the stability of the right-angle welding of the parts and improving the welding quality. When the bending angle transmission plate 5 moves, the guide hole and the guide rod 9 cooperate with each other, which can keep the bending angle transmission plate 5 moving in a straight line to avoid deviation and affect the stability of subsequent extrusion and fixation. When the screw 7 rotates to drive the U-shaped pressure rod 8 to move downward, the limit rod 10 can be used to limit the U-shaped pressure rod 8 to avoid the U-shaped pressure rod 8 and the screw 7 from rotating. When the screw 7 is twisted, the hexagonal transmission block 11 can be used to facilitate workers to use tools to twist, thereby achieving the purpose of saving effort.
