DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] A multi-angle automatic tapping machine, see Figure 1 and Figure 3 , including a base 1, a support platform 2 is arranged on the upper side of the base 1, a workpiece to be processed is placed on the support platform 2, a frame 31 is fixed on the upper end of a body 3, a first hydraulic telescopic rod 32 is arranged at the rear end of the frame 31, an output end of the first hydraulic telescopic rod 32 is fixed to the inside of the frame 31, the first hydraulic telescopic rod 32 is fixed to the upper end of the base 1, a tap is arranged on the lower side of the body 3, starting the first hydraulic telescopic rod 32 can drive the body 3 to rise and fall as a whole, so as to use the tap on the lower side of the body 3 to process the workpiece, wherein the body 3, the frame 31 and the tap are all necessary components for tapping, belonging to the prior art, so they are not described in detail herein.

[0028] In the embodiments of this application, please refer to Figure 1 and Figure 2 Two groups of clamping structures and a placement groove 23 are provided on the upper side of the support table 2. The placement groove 23 is located between the two groups of clamping structures. The workpiece to be processed is placed in the placement groove 23, and the workpiece is clamped and fixed by the clamping structure.

[0029] Specifically, the clamping structure is composed of a fixed plate 40, a second hydraulic telescopic rod 41 and a clamping plate 42. The fixed plate 40 is fixed to the left and right sides of the upper end of the support platform 2, respectively. The second hydraulic telescopic rod 41 is fixed to the opposite sides of the fixed plates 40 on both sides, respectively. The clamping plate 42 is fixed to the output end of the second hydraulic telescopic rod 41. When the second hydraulic telescopic rods 41 on both sides are started at the same time, the clamping plates 42 on both sides can be driven to move, and the workpiece can be clamped by the clamping plates 42 and fixed on the support platform 2.

[0030] For further information, see Figure 1 , Figure 3 and Figure 4A connecting block 21 is fixed to the lower side of the right end of the support platform 2, and a docking block 11 is rotatably connected to the outer side of the connecting block 21. The docking block 11 is fixed to the upper end of the base 1, so that the support platform 2 can perform circular motion with the connection between the connecting block 21 and the docking block 11 as the axis.

[0031] For further information, see Figure 1-4 , two groups of adjustment components connected to the base 1 are arranged on the left side of the lower end of the support platform 2, and the adjustment structure also includes a second electric telescopic rod 50 fixed inside the base 1, and a support block 51 is fixed to the output end of the second electric telescopic rod 50, and a pulley 52 is arranged on the outer side of the support block 51. At the same time, a limited cavity 22 is arranged on the left side of the lower end of the support platform 2, and a limited groove 221 is arranged on the inner wall of one side of the limited cavity 22. The support block 51 is movably connected to the inside of the limited cavity 22, and the pulley 52 is movably connected to the limited groove 221. The movable range of the pulley 52 is limited by the limited groove 221, and when the second electric telescopic rod 50 is started and the support block 51 is driven to rise, the side of the support platform 2 close to the adjustment structure is lifted, and the connection between the connecting block 21 and the docking block 11 is used as the axis to perform circular motion. At this time, the support platform 2 is deflected and the angle changes. The extension and retraction of the second electric telescopic rod 50 can drive the support platform 2 to perform multi-angle adjustment.

[0032] Working principle: the workpiece to be processed is placed in the upper placement groove 23 of the support table 2, and the second hydraulic telescopic rod 41 is started to drive the clamping plate 42 to move and clamp the workpiece. After the workpiece is clamped, the second electric telescopic rod 50 is started to drive the support block 51 to rise. During the rising process of the support block 51, the movement of the pulley 52 is limited by the limit groove 221, so that the support block 51 can drive the support table 2 to move in a circle with the connection between the connecting block 21 and the docking block 11 as the axis during the rising process, so that the support table 2 is deflected. When the angle of the threaded hole required to be processed in the workpiece is determined, the second electric telescopic rod 50 is stopped so that the support table 2 maintains this angle to facilitate processing of the workpiece.
