DETAILED DESCRIPTION

[0017] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0018] A welding tool for an engine base, such as Figure 1-Figure 4As shown, it includes an operating table 1, a motor 2, a bidirectional screw 3, a clamp 4 and an extrusion mechanism. The motor 2 is installed on the top right side of the operating table 1, and the bidirectional screw 3 is installed on the output shaft of the motor 2. The motor 2 is connected to the bidirectional screw 3 through a coupling, and the bidirectional screw 3 is rotatably connected to the operating table 1. The left and right sides of the bidirectional screw 3 are threadedly connected with clamps 4. Two through holes are opened on the top of the operating table 1. The left and right clamps 4 are slidably connected to the operating table 1 through corresponding through holes. The tops of the clamps 4 are connected with extrusion mechanisms, which are used to squeeze and fix the engine base. When the engine base needs to be welded, the engine base is placed on the operating table 1 so that the engine base is located between the left and right clamps 4. The left and right clamps 4 are made to approach each other and clamp the engine base through the motor 2, and then the extrusion mechanism is used to squeeze and fix the engine base, and then the engine base is welded. After welding, the left and right clamps 4 are moved away from each other by the motor 2 to loosen the engine base, and then the engine base is taken out to complete the welding. The motor 2 is used to control the clamp 4 to clamp the engine base, and the operation is simple and convenient.

[0019] like Figure 1-Figure 4 As shown, it also includes a slide bar 5, a first elastic member 6 and a pressure plate 7. The top of the clamping block 4 is slidably connected to the slide bar 5, and the top of the slide bar 5 is fixedly connected to the pressure plate 7. The first elastic member 6 is fixedly connected between the pressure plate 7 and the clamping block 4, and the first elastic member 6 is set as a spiral spring. When the engine base is placed between the left and right clamping blocks 4, the left and right pressure plates 7 are pulled upward to stretch the first elastic member 6, and then the clamping block 4 is driven by the motor 2 to clamp the engine base, and the left and right pressure plates 7 are released to restore the first elastic member 6 to its original state, so that the left and right pressure plates 7 move downward to clamp the engine base. After the engine base is welded, the left and right pressure plates 7 are pulled upward, and then the clamping block 4 is driven by the motor 2 to release the engine base. Finally, the engine base can be taken out, and the engine base is pressed and fixed by the pressure plate 7, which further improves the fixing effect of the tooling.

[0020] like Figure 1-Figure 4 As shown, a protective cover 8 is also included. The side of the pressing plates 7 that are close to each other is fixedly connected with the protective cover 8. The protective cover 8 is made of rubber material, which can increase the friction between the protective cover 8 and the engine base and protect the engine base. When the pressing plate 7 is moved downward to press the engine base, friction between the pressing plate 7 and the engine base is prevented to cause wear of the engine base.

[0021] like Figure 1 , Figure 3 and Figure 4As shown, it also includes a seesaw 9, a rotating plate 10, a telescopic rod 11 and a top plate 12. Two slide grooves are opened on the left and right sides of the top of the operating table 1. The bottom of the operating table 1 is hinged with a seesaw 9, and the rear left and right sides of the seesaw 9 are hinged with a rotating plate 10. The top of the rotating plate 10 is rotatably connected with the telescopic rod 11. The maximum extension distance of the telescopic rod 11 is equal to half of the distance from the top of the operating table 1. The inner rods of the left and right telescopic rods 11 are located on the side of the rotating plate 10 away from each other. The inner rods of the telescopic rods 11 are fixedly connected with the top plate 12. The top of the top plate 12 is fixedly connected to the pressure plate 7, and the top plate 12 is slidably connected to the slide groove of the operating table 1. A circular avoidance hole is opened in the middle of the top plate 12 to prevent the top plate 12 from contacting the bidirectional screw rod 3. The seesaw 9 is in a flat state when there is no external force.

[0022] When it is necessary to lift the pressure plate 7 upward, step on the rocker 9 downward to move its rear side upward, and the rocker 9 drives the rotating plate 10 to rotate and move upward at the same time, and the rotating plate 10 moves upward and drives the top plate 12 to move upward through the telescopic rod 11, so that the top plate 12 drives the pressure plate 7 to move upward and drives the first elastic member 6 to stretch. After the engine base is clamped by the clamping block 4, the rocker 9 is released, and the first elastic member 6 is reset so that the top plate 12, the telescopic rod 11, the rotating plate 10 and the rocker 9 are reset at the same time. When the engine base is large, the top plate 12 can cooperate with the movement of the clamping block 4 through the extension of the telescopic rod 11, and there is no need to manually lift the pressure plate 7, making the use of this tooling more convenient.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, a pedal 16 is also included, and the front side of the seesaw 9 is fixedly connected to the pedal 16, the front and rear sides of the pedal 16 are open, and the top of the pedal 16 is provided with a pattern. When the pressing plate 7 needs to be lifted upward, the seesaw 9 is rotated by stepping on the pedal 16, which can protect the seesaw 9 and improve the efficiency of the seesaw 9.

[0024] like Figure 1 and Figure 3 As shown, it also includes a fixed rod 13, a shielding rod 14 and a second elastic member 15. A sliding hole is opened on the top of the front side of the operating table 1, and the fixed rod 13 is fixedly connected in the sliding hole. The shielding rod 14 is slidably connected to the fixed rod 13. The second elastic member 15 is fixedly connected between the shielding rod 14 and the sliding hole. The fixed rod 13 passes through the second elastic member 15. The bottom of the shielding rod 14 is a triangle. The right end of the triangle at the bottom of the shielding rod 14 is longer than the left side of the pedal 16, and its inclined surface is smooth and close to the pedal 16. A handle is provided on the top of the shielding rod 14 to facilitate the movement of the shielding rod 14.

[0025] At first, the bottom of the shielding rod 14 is located below the pedal 16. When the pedal 16 is stepped on to move the pressure plate 7 upward through the rocker 9, the pedal 16 moves downward to squeeze the triangular inclined surface at the bottom of the shielding rod 14, so that the shielding rod 14 moves to the left along the fixing rod 13, and the second elastic member 15 is squeezed. When the pedal 16 moves downward to the bottom of the shielding rod 14, the pedal 16 no longer squeezes the shielding rod 14, and the second elastic member 15 returns to its original state to reset the shielding rod 14, so that the bottom triangle of the shielding rod 14 is located at the top of the pedal 16, thereby jamming the pedal 16. After releasing the pedal 16, the pedal 16 will not reset. When the pedal 16 needs to be reset, it is only necessary to move the shielding rod 14 to the left. When the bottom of the shielding rod 14 is located at the top of the pedal 16, the rocker 9 can be kept in a tilted state. There is no need to keep stepping on the pedal 16, which is more convenient for fixing the engine base.

[0026] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications and equivalent structures and functions.
