A rectangular center seat is drivenly connected to the lower end of the cylinder. Rectangular side strips are fixedly connected to the two side walls of the center seat. A motor base is movably connected to the outer side of the side strips. A screw is threadedly connected to the front top wall of the motor base. A motor is fixedly connected inside the motor base. A drill bit for drilling welded pipes is drivenly connected to the lower end of the motor base.

[0007] Preferably, a cylindrical rotating column is rotatably connected to the center of the bottom end wall inside the frame, and a disc-shaped support is fixed to the top wall of the rotating column.

[0008] Preferably, a sliding bar is radially movably connected to the end wall of the support, and four sliding bars are provided, which are distributed in a ring about the center of the support.

[0009] Preferably, a three-jaw clamp is fixedly connected to the end of the slider away from the support, and four three-jaw clamps are provided.

[0010] Preferably, the upper wall of the support is threaded with four screws for tightening the slider after adjusting its position.

[0011] Preferably, a screw is vertically threaded through and connected to the end wall of the support near the slide bar, and four screws are provided, which are distributed in a ring about the center of the support.

[0012] This utility model has at least the following beneficial effects:

[0013] The cylinder operates, driving the central seat to move downwards. The side strip and motor seat move downwards synchronously. As the motor moves downwards, the drill bit driven by the motor also moves downwards to drill holes in the automotive welded pipe fittings. There are two motors, which are used to drill two welded pipe fittings simultaneously, improving the efficiency of drilling. The side strip and motor seat are movable, allowing the motor seat to slide sideways along the length of the side strip. Changing the position of the motor seat makes it easier to change the drilling position on the welded pipe fittings, making the processing more flexible and convenient. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for an automotive welded pipe drilling machine:

[0022] like Figure 1-4As shown, an automotive welded pipe drilling machine includes a rectangular frame 1 with a rectangular cavity in the middle. A cylinder 2 is fixedly connected to the top wall of the frame 1. A rectangular middle seat 3 is drivenly connected to the lower end of the cylinder 2. Rectangular side strips 4 are fixedly connected to the two side walls of the middle seat 3. A motor seat 5 is movably connected to the outer side of the side strips 4. A screw 6 is threadedly connected to the front wall of the top of the motor seat 5. A motor 7 is fixedly connected inside the motor seat 5. A drill bit 8 for drilling welded pipes is drivenly connected to the lower end of the motor seat 5.

[0023] A cylindrical rotating column 9 is rotatably connected to the center of the bottom end wall inside the frame 1, and a disc-shaped support 10 is fixed to the top wall of the rotating column 9.

[0024] A slide bar 11 is radially movably connected to the end wall of the support 10. There are four slide bars 11, which are arranged in a ring around the center of the support 10. A three-jaw clamp 13 is fixed to the end of the slide bar 11 away from the support 10. There are four three-jaw clamps 13.

[0025] The upper end wall of the support 10 is threaded with screws 12 for tightening the slider 11 after adjusting its position. There are four screws 12. The end wall of the support 10 adjacent to the slider 11 is vertically threaded with screws 14. There are four screws 14, which are distributed in a ring around the center of the support 10.

[0026] Working principle:

[0027] When cylinder 2 operates, it drives the central seat 3 to move downward, and the side strip 4 and motor seat 5 move downward synchronously. The motor 7 moves downward, and the drill bit 8 driven by the motor 7 moves downward accordingly to drill holes in the automotive welded pipe fittings. There are two motors 7, which are used to drill two welded pipe fittings simultaneously, improving the efficiency of drilling. The side strip 4 and motor seat 5 are movable to slide the motor seat 5 sideways, so that the motor seat 5 moves along the length of the side strip 4. Changing the position of the motor seat 5 makes it easier to change the drilling position of the welded pipe fittings, making the processing more flexible and convenient. Tightening the screw 6 locks and limits the side strip 4.

[0028] The support 10 is connected to a three-jaw chuck 13 via a slide bar 11. The three-jaw chuck 13 is used to grip and position the welded pipe fittings. The slide bar 11 moves and moves laterally to change the position of the three-jaw chuck 13, which facilitates fine-tuning of the position of the welded pipe after positioning. It is used in conjunction with the drilling part for drilling. There are four slide bars 11 and four three-jaw chucks 13 to grip and position four pipe fittings. When the rotating column 9 rotates, the support 10 is rotated, which drives the four three-jaw chucks 13 on the side of the support 10 to rotate, so that the welded pipe fittings gripped by the three-jaw chucks 13 can be rotated to switch positions and alternately switch to below the drill bit 8 for convenient and rapid processing of pipe fittings.

[0029] A rectangular opening runs through the bottom of the side wall of frame 1, through which welded pipes extend out of frame 1, facilitating the positioning and placement of longer welded pipes.

[0030] Among them, tightening screw 12 is used to lock slide bar 11 after limit adjustment position, screw 14 is tightened, the lower end of screw 14 moves down and contacts the end wall of frame 1, which is used to limit the rotation of support 10, so that support 10 is in a stable state and the welded pipe is stably positioned.

[0031] 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 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 claimed utility model.
