[0002] Machining is any process within the production process that changes the shape, size, position, or properties of a product to produce a finished or semi-finished product. It is a key component of the production process. Processes can be further categorized as casting, forging, stamping, welding, machining, and assembly. Mechanical manufacturing processes generally refer to the combined machining of parts and assembly of machines.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] like Figure 1-3The precision machining welding device with a docking positioning mechanism shown in the figure includes a processing table 1, a clamping seat 2 is set on the processing table 1, and also includes a positioning mechanism, which is composed of a moving seat 3 and a rotating seat 4. The clamping seat 2 is fixed on the moving seat 3 and the rotating seat 4 respectively. The moving seat 3 is connected to the output end of the electric push rod 31 and is pushed and slidably connected to the processing table 1 by the electric push rod 31. The rotating seat 4 is rotatably connected to the processing table 1 through a rotating shaft 41. A helical gear 42 is fixed on the rotating shaft 41, and the helical gear A worm shaft 43 is meshedly connected to 42, and the worm shaft 43 is driven to rotate by a motor 44. A slide groove 21 is provided on the clamping seat 2, and sliders 22 are provided on both sides of the slide groove 21. A screw rod 23 is provided in the slide groove 21, and the screw rod 23 is composed of a pair of screw shafts 24 with opposite thread rotation directions. A nut 25 is provided on the screw shaft 24, and the nut 25 is connected and fixed to the slider 22 on the corresponding side. A splint 5 is fixed on the slider 22, and one end of the screw rod 23 passes through the clamping seat 2 and is connected to a knob 26.

[0021] As a preferred embodiment, an embedding groove 51 is provided on the inner side of the splint 5 , a limiting block 52 is inserted into the embedding groove 51 , and the limiting block 52 is slidably connected to the embedding groove 51 via a spring 53 .

[0022] As a further improvement, the clamping plate 5 is in sliding contact with the clamping seat 2 .

[0023] As a further improvement, the embedding grooves 51 are provided in pairs on the clamping plates 5 on both sides of the clamping base 2 in multiple groups.

[0024] As a further improvement, a fastening pad 54 is provided at one end of the limiting block 52 extending out of the embedding groove 51 .

[0025] The present invention mentions a precision machining welding device with a docking positioning mechanism, which can position and adjust the welding docking position and the angle between the two rod workpieces to be welded after clamping, thereby ensuring the quality of the welding.

[0026] Specifically, when in use, a rod workpiece can be placed on the clamping seat 2 on the movable seat 3, and by rotating the knob 26, the screw mechanism controls the contraction of the clamping plate 5 until the clamping plates 5 on both sides clamp and fix the outer wall of the workpiece, thereby achieving the fixation of the workpiece.

[0027] Next, another workpiece is placed on the clamping seat 2 on the rotating seat 4. At the same time, the knob 26 is also rotated so that the screw mechanism controls the clamping plate 5 to clamp the outer walls on both sides of the workpiece. As the clamping plate 5 contracts, the limit block 52 on its inner side gradually fits tightly and is limited to the outer wall of the workpiece, thereby achieving fit and limit of the workpiece. Then, the worm shaft 43 is driven by the motor 44 to rotate, so that it engages with the bevel gear 42, and then drives the rotation of the rotating shaft 41, that is, controls the rotation of the rotating seat 4, so that the angle of the workpiece clamped and limited on the clamping seat 2 is adjusted and controlled. At this time, after the workpiece contacts the workpiece on the clamping seat 2 on the moving seat 3, it begins to adjust and position according to demand.

[0028] During adjustment, as the rotating base 4 continues to rotate, the workpiece on the clamping base 2 on the mobile base 3 is clamped and fixed. As the rotating base 4 continues to rotate, the workpiece on the clamping base 2 on the rotating base 4 is subjected to the resistance force of the workpiece on the clamping base 2 on the mobile base 3, that is, it is pushed backward in the opposite direction. At the same time, the contact point between the workpiece on the clamping base 2 on the mobile base 3 is also translated horizontally on the workpiece. Then, due to the change in the translation of the contact point, the angle between the two is also adjusted. When the angle is adjusted to the desired position, the motor 44 is turned off and the knob 26 is rotated again, so that it drives the control clamping plate 5 to continue to retract until the clamping plate 5 on the clamping base 2 on the rotating base 4 clamps the workpiece.

[0029] At this point, the angle between the two workpieces is adjusted, and then the electric push rod 31 can be used to push the movable base 3 to move horizontally, thereby achieving the positioning adjustment control of the welding contact point between the two workpieces after the angle adjustment. Finally, the contact position can be welded by the welding gun.

[0030] In addition, the clamping plate 5 on the clamping seat 2 is provided with multiple sets of limit blocks 52 on its inner side. When the clamping plate 5 is clamped on the outer wall of the workpiece, the limit blocks 52 can also simultaneously apply a clamping force to the outer wall of the clamped workpiece under the elastic force of the spring 53, further improving the clamping and fixing effect. At the same time, when it is used on the clamping plate 5 on the clamping seat 2 on the rotating seat 4, during the angle adjustment process, when the clamping plate 5 is not completely clamped on the outer wall of the workpiece, the limit blocks 52, under the action of the spring 53, provide an elastic clamping force on the outer wall of the workpiece, which can not only ensure the position of the workpiece, but also enable the workpiece to achieve radial movement in the radial direction formed by the two clamping plates 5, facilitating the angle adjustment when the workpieces are docked.

Any modifications and improvements made to the technical solution of the present invention by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention.
