[0022] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.
[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 A mechanical parts welding positioning device is shown.
[0024] The first embodiment of the utility model refers to Figure 1 , Figure 2 and Figure 3 As shown, a mechanical part welding positioning device comprises a base plate 1, the base plate 1 is a quadrilateral plate structure with a certain thickness, an upwardly protruding fixed frame 5 is fixedly arranged on the upper surface of the base plate 1, a vertical support 51 is also extended upwardly at the plane position on the base plate 1, a protruding rod 52 is protruded upwardly at the top of the vertical support 51, a support ring 55 and a limiting rod 54 are fixedly connected on the upper plane of the base plate 1, a frame block 53 is fixedly connected to the limiting rod 54, and the frame block 53 is fixedly installed on the upper surface of the base plate 5 by the limiting rod 54. When in use, a mechanical part 4 is placed on the top of the frame block 53, and a steel cap 41 is placed at the welding position on the top of the mechanical part 4;
[0025] A support frame 3 is fixedly provided on the upper plane of the substrate 1 and extends upward. A cylinder 32 is provided on the top of the support frame 3. A push piece 33 is fixedly provided on the bottom of the cylinder 32 through the support frame 3. A welding head 34 for welding the steel cap 41 and the mechanical part 4 is provided on the push piece 33. A guide column 31 is provided on the top of the push piece 33. The guide column 31 passes through the support frame 3 and extends upward. The guide column 31 is slidably connected to the support frame 3, and the push piece 33 is vertically limited by the guide column 31.
[0026] When in use, the mechanical part 4 is placed on the upper surface of the support ring 55 and the frame block 53 on the fixed frame 5, and the steel cap 41 is placed at the welding position on the mechanical part 4. The mechanical part 4 can be kept horizontal by the support ring 55 and the frame block 53 to avoid the steel cap 41 on the mechanical part 4 sliding at the welding position due to the mechanical part 4 not being placed horizontally during welding, thereby causing the welding position of the steel cap 41 to deviate. Then, the cylinder 32 on the support frame 3 is controlled to operate, and the cylinder 32 drives the push piece 33 to move downward, and the push piece 33 drives the welding head connected to the bottom to move toward the welding position in the mechanical part 4, so as to weld the mechanical part 4 and the steel cap 41; at the same time, the guide column 31 on the push piece 33 slides on the support frame 3, thereby limiting the stability of the push piece 33 in the up and down displacement, and preventing the push piece 33 from deviating left and right during the movement, thereby ensuring the accuracy of the welding position.
[0027] The second embodiment of the utility model refers to Figure 1-Figure 4 As shown, a support seat 2 is fixedly installed on the upper plane of the base plate 1. The support seat 2 includes a bracket 21, a tooling block 22 fixedly arranged on the bracket 21, and a slot pushing block 24 slidably arranged on the bracket 21. The center position of the slot pushing block 24 has a notch, and a pressure handle 25 is hingedly connected to the notch. Preferably, the slot pushing block 24 and the pressure handle 25 are hingedly matched by a rotating pin; a hinge 23 is hingedly connected between the tooling block 22 and the pressure handle 25, and a rotating shaft is installed at the upper and lower parts of the hinge 23, and the rotating shaft is rotatably connected to the outer wall of the tooling block 22 and the pressure handle 25 respectively. A lifting ear 42 is fixedly provided on the convex rod 52 at the top of the vertical support 51, and a pressure plate is provided at the bottom of the lifting ear 42 extending toward the fixed frame 5. The position of the mechanical part 4 can be temporarily fixed by the pressure plate at the bottom of the lifting ear 42. The bracket 21 is built with a motor for driving the slot pushing block 24 to extend or shorten;
[0028] After the mechanical part 4 is placed on the limit rod 53 and the fixed frame 55, the position of the mechanical part 4 is initially limited by the pressure plate at the bottom of the ear 42. After the mechanical part 4 is placed, the motor built into the bracket 21 is started to operate, and the driving end of the motor pushes the groove pushing block 24 to extend or shorten on the bracket 21; when the motor drives the groove pushing block 24 to shorten on the bracket 21, the groove pushing block 24 pulls the pressing handle 25 to detach upward from the surface of the mechanical part 4; when the motor drives the groove pushing block 24 to extend on the bracket 21, the groove pushing block 24 pushes the pressing handle 25 to move toward the upper surface of the mechanical part 4, thereby squeezing and fixing the mechanical part 4 downward, so that the mechanical part 4 can be firmly fixed on the top of the fixed frame 5.
[0029] One end of the fixed frame 5 close to the upper plane of the substrate 1 is fixedly connected with a docking plate 56 . The docking plate 56 is fixedly arranged at an inner position of the fixed frame 5 . The fixed frame 5 and the substrate 1 are firmly fixed by the docking plate 56 .
[0030] When using the utility model, a fixed frame 5 is arranged on the surface of the substrate 1, and a frame block 53 and a support ring 55 are arranged on the fixed frame 5. The mechanical part 4 is supported by the frame block 53 and the support ring 55 to prevent the steel cap 41 from deviating from the position when the mechanical part 4 and the steel cap 41 are assembled; the motor built into the start bracket 21 is operated, and the driving end of the motor pushes the groove pushing block 24 to extend or shorten. After shortening, the pressing handle 25 is pushed to detach from the upper surface of the mechanical part 4. On the contrary, the groove pushing block 24 is extended, and the connected pressing handle 25 is displaced toward the upper surface of the mechanical part 4, thereby squeezing and fixing the mechanical part 4, so that it is firmly fixed on the top support ring 55 and the frame block 53 of the fixed frame 5. The cylinder 32 on the control support frame 3 is operated, and the cylinder 32 drives the push piece 33 to move downward. The push piece 33 drives the welding head connected to the bottom to move to the welding position in the mechanical part 4, so as to weld the mechanical part 4 and the steel cap 41; at the same time, the guide column 31 on the push piece 33 slides on the support frame 3, so as to limit the stability of the push piece 33 in the up and down displacement, and prevent the push piece 33 from shifting left and right during the movement, so as to ensure the accuracy of the welding position.
