[0018] A double-servo automatic tapping machine, comprising two columns 1 arranged in parallel, the column 1 is provided with a fixture 2 sleeved on the column 1 and capable of moving up and down along the column 1, the fixture 2 is provided with a mounting plate 3 connected to the fixture 2, the mounting plate 3 is provided with a linear guide rail 4, and a tap mounting frame 5 is provided on the linear guide rail 4 and can move along the linear guide rail 4;

[0019] The upper parts of the two columns 1 are arranged on a workbench 6 , and the lower part of the workbench 6 is provided with front and rear linear guide rails 7 for driving the workbench 6 to move forward and backward, and left and right linear guide rails 8 for driving the workbench 6 to move left and right.

[0020] Further, a mounting structure 9 for mounting the tap is provided at the lower part of the tap mounting frame 5, the mounting structure 9 includes a mounting sleeve 91 for mounting the tap, the mounting sleeve 91 is provided with a mounting hole 92 corresponding to the tap profile, and a receiving cavity 93 of the mounting structure 9 for accommodating the mounting sleeve 91 is larger than the size of the mounting sleeve 91, and the receiving cavity 93 forms a space for horizontal movement of the mounting sleeve 91;

[0021] A plurality of positioning holes 94 are provided on the side of the mounting structure 9 corresponding to the side of the mounting sleeve 91 , and a fastener 10 is provided to pass through the positioning holes 94 and abut against the surface of the mounting sleeve 91 to position the mounting sleeve 91 .

[0022] Furthermore, the positioning hole 94 is a threaded hole, the fastener 10 is screwed into the positioning hole 94 and abuts against the surface of the mounting sleeve 91, and the contact surface between the mounting sleeve 91 and the fastener 10 is a plane.

[0023] Furthermore, each positioning hole 94 is provided with a movable elastic rod 95 on the inner surface edge of one side of the mounting sleeve 91. When the fastener 10 is screwed into the positioning hole 94, the elastic rod 95 is pushed out to both sides. The two adjacent elastic rods 95 in contact are arranged on different straight lines to form rotation constraints on each other.

[0024] The present invention is further described below to better understand the present invention: the worktable 6 of the dual-servo automatic tapping machine of the present invention can move in the X and Y directions through linear guides, the dual-servo tapping machine is connected to the special machine column 1 through a clamp 2, and the height can be adjusted up and down, the dual-servo tapping machine can move in the X direction through a linear guide, the X and Y displacements of the worktable 6 and the X-direction displacement of the dual-servo tapping machine are driven by stroke-adjustable cylinders respectively, the strokes at both ends of the cylinders can be adjusted, and the extension and retraction of the cylinder and the dual-servo tapping machine are controlled by a programmable controller.

[0025] An innovation of the present invention lies in the design of the mounting structure 9. When the position of the tap needs to be adjusted during use, the fastener 10 is first screwed out of the positioning hole 94, and then the mounting sleeve 91 is moved along the sliding groove 93. When the mounting sleeve 91 moves to the preset position, the fastener 10 is screwed into the positioning hole 94 and abuts against the surface of the mounting sleeve 91 to position the mounting sleeve 91. At the same time, the fastener 10 pushes the elastic rod 95 to both sides. Due to the constraints of the adjacent elastic rods 95, the fastener 10 is subject to certain constraints during use and will not rotate, thereby further ensuring the tightness of the connection between the fastener 10 and the mounting sleeve 91 and ensuring that the mounting sleeve 91 is tightened.
