Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for welding equipment for mechanical parts. Background Technology

[0002] In the welding process, in order to ensure the stability of the welding of mechanical parts, the mechanical parts to be welded are clamped and fixed. Right angle clamps are commonly used clamps. However, when using right angle clamps, the movable clamping blocks cooperate with the fixed blocks to clamp and fix the welded parts. However, the upper part of the clamped workpiece cannot be effectively positioned. This can easily cause the welded parts to tilt at an imperceptible angle during the clamping process, which will affect the welding. Utility Model Content

[0003] The main purpose of this utility model is to provide a fixture for welding equipment of mechanical parts, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A fixture for welding mechanical parts includes a base and a clamping block. Fixing blocks are installed on the upper surface of the base and on both sides. A fixing plate is installed above the rear end of the base. A threaded sleeve is installed between the fixing plate and the base. A screw that passes through the threaded sleeve and is rotatable is installed behind the clamping block. A pressure plate is installed in front of the clamping block.

[0006] More preferably, the front surface of the clamping block has a groove in the middle, the inside of the groove has a vertically extending lifting groove, the upper surface of the clamping block has a knob in the middle, the lower surface of the knob has a threaded shaft extending into the lifting groove, and the front surfaces of both sides of the clamping block have longitudinally extending limiting grooves.

[0007] More preferably, a threaded sleeve block sleeved on the threaded shaft is installed on the rear surface of the pressure plate and in the middle, and a limiting block embedded in the limiting groove is installed on the rear surfaces of both ends of the pressure plate.

[0008] More preferably, the fixing plate is fixed to the base by fasteners, and the height of the clamping block is greater than the height of the fixing block.

[0009] Compared with the prior art, this utility model proposes a fixture for welding equipment of mechanical parts, which has the following beneficial effects:

[0010] In this invention, by setting up a clamping block and a pressure plate to cooperate with each other, when the screw is rotated, the screw pushes the clamping block to move and clamps the two mechanical parts that need to be welded together between the fixed blocks, the knob is rotated, the knob drives the threaded shaft to rotate, and the rotating threaded shaft causes the pressure plate with the threaded sleeve on it to descend until the pressure plate presses on the clamped mechanical parts. This can limit the upper part of the mechanical parts, thereby effectively clamping and positioning the mechanical parts. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] like Figure 1-3 As shown, a fixture for welding mechanical parts includes a base 1 and a clamping block 6. Fixing blocks 2 are installed on the upper surface of the base 1 and on both sides. A fixing plate 3 is installed above the rear end of the base 1. A threaded sleeve 4 is installed between the fixing plate 3 and the base 1. A screw 5 that passes through the threaded sleeve 4 and can rotate is installed behind the clamping block 6. A pressure plate 7 is installed in front of the clamping block 6.

[0019] In a preferred embodiment: a groove 605 is provided on the front surface of the clamping block 6 at the center, a lifting groove 601 is provided longitudinally inside the groove 605, a knob 602 is installed on the upper surface of the clamping block 6 at the center, a threaded shaft 603 extending into the lifting groove 601 is installed on the lower surface of the knob 602, and limit grooves 604 are provided longitudinally on the front surfaces of both sides of the clamping block 6.

[0020] In the above structure, the threaded shaft 603 can be rotated by rotating the knob 602 in both directions. The rotating threaded shaft 603 causes the pressure plate 7 with the threaded sleeve on it to rise and fall. When the pressure plate 7 falls, the two mechanical parts to be welded can be pressed on the base 1 and kept in a horizontal state. The groove 605 can keep the front end of the pressure plate 7 and the front end of the clamping block 6 horizontal, so as to avoid the front end of the pressure plate blocking the welding part and affecting the welding.

[0021] In a preferred embodiment: a threaded sleeve block 701 sleeved on the threaded shaft 603 is installed on the rear surface of the pressure plate 7 and located in the middle, and limit blocks 702 embedded in the limit grooves 604 are installed on the rear surfaces of both ends of the pressure plate 7.

[0022] In the above structure, since the limiting block 702 is embedded in the limiting groove 604, the pressure plate 7 can remain horizontal when it is raised or lowered.

[0023] In a preferred embodiment: the fixing plate 3 is fixed to the base 1 by fasteners, and the height of the clamping block 6 is greater than the height of the fixing block 2.

[0024] In the above structure, since the height of the clamping block 6 is greater than the height of the fixing block 2, when the pressure plate 7 is not in use, the pressure plate 7 can be raised by rotating the knob 602 until the pressure plate 7 exceeds the height of the fixing block 2. This prevents the clamping block 6 from being blocked by the pressure plate 7 when clamping mechanical parts with a width smaller than the pressure plate 7.

[0025] In use, when the screw 5 is rotated and moves within the threaded sleeve 4, pushing the clamping block 6 to hold the two mechanical parts to be welded together between the fixing block 2, the knob 602 is rotated. The knob 602 drives the threaded shaft 603 to rotate. The rotating threaded shaft 603 causes the pressure plate 7 threaded on it to descend until the pressure plate 7 presses down on the clamped mechanical parts. This limits the upper part of the mechanical parts, thus effectively clamping and positioning them. When the pressure plate 7 is not in use, the knob 602 is rotated in the opposite direction to raise the pressure plate 7 until the height of the pressure plate 7 exceeds the height of the fixing block 2.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
