[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model discloses a multifunctional fixture, including a bottom plate 10. A pair of columns 20 are fixedly connected to the top surface of the bottom plate 10. An outer frame 30 is rotatably connected between the two columns 20. A motor 40 is bolt-mounted on one side of one of the columns 20. The motor 40 is in transmission connection with the outer frame 30. A left and right screw rod 50 and a guide rod 60 are arranged inside the outer frame 30. A pair of limiting mechanisms 70 are sleeved on the guide rod 60. The limiting mechanisms 70 are in threaded connection with the left and right screw rod 50. A positioning mold 80 is arranged between the two limiting mechanisms 70.

[0023] Specifically, both ends of the guide rod 60 are fixedly connected to the inner walls of both sides of the outer frame 30 respectively. Both ends of the left and right screw rod 50 are axially connected to the inner walls of both sides of the outer frame 30 respectively. A turning handle 90 is rotatably connected to the other side of the outer frame 30. One end of the turning handle 90 is fixedly connected to the other end of the left and right screw rod 50 by screws.

[0024] In this implementation scheme, the installation methods of the guide rod 60 and the left and right screw rod 50 are disclosed, and the provided turning handle 90 facilitates driving the rotation of the left and right screw rod 50.

[0025] Specifically, a support plate 100 is arranged between the two columns 20 and is slidably connected to the two columns 20 up and down. Mounting holes 110 are respectively opened above the sides of the two columns 20 away from each other.

[0026] In this embodiment, when machining and assembling workpieces (devices), etc., the position of the support plate 100 can be adjusted upward to support the placement of the workpieces (devices). When welding the workpieces, the position of the support plate 100 is lowered and attached to the bottom plate 10, without interfering with the rotation of the outer frame 30.

[0027] Specifically, the limiting mechanism 70 includes a slider 71. The slider 71 is slidably connected to the guide rod 60, and the slider 71 is threadedly connected to the left and right screw rods 50. A pair of circular holes 72 are formed on one side of the slider 71. A groove 73 is formed on the side of the slider 71 close to the positioning die 80. A limiting pressing piece 74 is provided in the groove 73 and is inclinedly slidably connected to the front and rear inner walls thereof. A spring is welded to the end of the limiting pressing piece 74 away from the positioning die 80, and the spring is welded to the inner wall of the groove 73 away from the positioning die 80. A fastening bolt 75 is threadedly connected to the top surface of the slider 71. The bottom end of the fastening bolt 75 is integrally connected with a circular pressing piece, and the circular pressing piece is attached to the top surface of the limiting pressing piece 74. The positioning die 80 is a die body 81, and a pair of clamping columns 82 are integrally connected to both sides of the die body 81.

[0028] In this embodiment, the shape and size of the die body 81 can be flexibly adjusted according to the size and shape of the two workpieces to be welded. When welding is required, align the clamping columns 82 with the circular holes 72, and snap the pair of clamping columns 82 into the circular holes 72. Rotate the rotating handle 90 clockwise, and the left and right screw rods 50 rotate clockwise and drive the two limiting mechanisms 70 to move closer to each other. Finally, each clamping column 82 is correspondingly snapped into the circular hole 72. Place the two workpieces to be welded on the die body 81, and then rotate the fastening bolt 75 clockwise. At this time, the circular pressing piece below the fastening bolt 75 rotates and moves downward, and the circular pressing piece squeezes the limiting pressing piece 74 to move downward obliquely. The bottom surface of the limiting pressing piece 74 is attached to the top surface of the workpiece, and the spring is elastically stretched, so as to lock the workpiece. First, weld the top connection end of the workpiece. After the welding is completed, start the motor 40 to drive the outer frame 30 to rotate 180 degrees, and then the bottom surface of the workpiece can be welded, with high welding quality.

[0029] Specifically, the positioning die 80 is a pair of clamping blocks 83. A pair of stud bolts 84 are integrally connected to the mutually remote sides of the two clamping blocks 83. The stud bolts 84 penetrate through the circular holes 72, and the stud bolts 84 are threadedly connected with nuts 85.

[0030] In this embodiment, the shape and size of the clamping block 83 can be flexibly adjusted according to the workpiece (device) to be processed or assembled. During use, the stud 84 is passed through the round hole 72, and then the nut 85 is threadedly connected to achieve fixed installation. Then, the support plate 100 is moved upward along the column 20 until it can no longer move upward. The screw is passed through the mounting hole 110 and threadedly fixed to the support plate 100, which can achieve the fixed installation of the support plate 100. The support plate 100 places the workpiece (device). Rotating the handle 90 clockwise drives the left and right screw rods 50 to rotate clockwise, and the two limiting mechanisms 70 move closer to each other. The two clamping blocks 83 move closer to each other and firmly clamp the workpiece (device), facilitating subsequent processing or assembly, etc.
