Description

Technical Field

[0001] The present application relates to the field of hydraulic tapping machines, and in particular to an adjustable tapping mechanism of a hydraulic tapping machine. Background Art

[0002] A tapping machine is a machine tool that uses a tap to process internal threads. It is the most widely used machine tool for processing internal threads. According to the type of driving power, tapping machines can be divided into manual tapping machines, pneumatic tapping machines, electric tapping machines and hydraulic tapping machines. During the operation of a hydraulic tapping machine, the tapping head is easily damaged due to long-term use or the quality of the tapping head itself. When the tapping head is damaged, it is necessary to replace the tapping head in time. However, when a general tapping machine replaces the tapping head, a threaded connector is set at the top of the tapping head, which is fixed to the machine body through the threaded connector. This fixing method is prone to loosening or becoming more and more tight and difficult to remove when the tapping head is processing the hole groove, which in turn affects production and processing and needs to be improved.

[0007] By adopting the above technical solution, by setting an adjustable element and using a bidirectional threaded rod to move the two connecting rods closer or farther away, the connecting plug is driven to insert or disengage from the locking hole, and tapping heads of different sizes can be installed and disassembled, which facilitates the replacement of tapping heads, has a simple structure and strong applicability.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The embodiments of the present application disclose an adjustable tapping mechanism of a hydraulic tapping machine.

[0022] Reference Figure 1-3 The adjustable tapping mechanism of the hydraulic tapping machine includes a driving mechanism 1, an adjustable element 2 is fixedly installed at the bottom end of the driving mechanism 1, and a tapping head 3 is arranged on the bottom surface of the adjustable element 2. The adjustable element 2 is used to connect the driving mechanism 1 and the tapping head 3. The adjustable element 2 includes a mounting block 4, a bidirectional threaded rod 8, a connecting rod 11 and a connecting plug block 13. The connecting rod 11 and the connecting plug block 13 are both set in two. A connecting block 5 is fixedly connected to the top surface of the tapping head 3. Locking holes 14 are opened on both sides of the connecting block 5. The inner wall of the locking hole 14 matches the outer wall of the connecting plug block 13. By setting the adjustable element 2, the bidirectional threaded rod 8 is used to drive the two sliding blocks 9 to move toward or away from each other, so that the two connecting rods 11 are close to or away from each other, driving the connecting plug block 13 to insert into or disengage from the locking hole 14, and tapping heads 3 of different sizes can be installed and disassembled, which provides convenience for replacing the tapping head 3, has a simple structure and strong applicability.

[0023] Reference Figure 2-3 The outer wall of the two-way threaded rod 8 is movably connected with two sliding blocks 9, the bottom surface of the sliding block 9 is fixedly connected to the top of the connecting rod 11, and the side of the connecting rod 11 is fixedly connected to the side of the connecting plug block 13. The outer wall of the mounting block 4 is rotatably connected with an anti-slip screw block 15, one end of the anti-slip screw block 15 is fixedly connected to one end of the two-way threaded rod 8, the connecting block 5 is placed in the mounting block 4, and the anti-slip screw block 15 is rotated to drive the two-way threaded rod 8 to rotate, thereby driving the two sliding blocks 9 to move toward each other. The movement of the sliding block 9 drives the connecting rod 11 on the bottom surface to move accordingly, and the connecting plug block 13 is inserted into the locking hole 14 to fix the tapping head 3. During disassembly, the anti-slip screw block 15 is reversed to drive the two sliding blocks 9 to move away from each other, thereby driving the connecting plug block 13 to disengage from the locking hole 14, and then the connecting block 5 is pulled out of the mounting block 4 to complete the disassembly.

[0024] Reference Figure 2-3, positioning grooves 7 are provided on both sides of the connecting block 5, and arc-shaped slide bars 6 are fixedly connected to both sides of the inner wall of the mounting block 4, and the outer wall of the arc-shaped slide bar 6 fits with the inner wall of the positioning groove 7. The connecting block 5 is inserted into the mounting block 4. At this time, the two arc-shaped slide bars 6 are respectively located in the two positioning grooves 7 on both sides of the connecting block 5, and the connecting block 5 is limited to facilitate alignment and correction, so that the connecting plug block 13 and the locking hole 14 are located on the same horizontal line;

[0025] The inner wall of the mounting block 4 is fixedly connected to the partition plate 10, and two limiting slide grooves are provided on the upper surface of the partition plate 10. The inner wall of the limiting slide groove is provided with a groove. A protrusion 12 is fixedly connected to the side of the connecting rod 11, and the outer wall of the protrusion 12 is slidably connected to the inner wall of the groove. The connecting rod 11 extends through the limiting slide groove to the bottom of the sliding block 9. When the two sliding blocks 9 drive the connecting rod 11 to move, the protrusion 12 moves along the inner wall of the groove, thereby improving the stability of the movement of the connecting rod 11.

[0026] The implementation principle of the adjustable tapping mechanism of the hydraulic tapping machine in the embodiment of the present application is as follows: when in use, the connecting block 5 is placed in the mounting block 4, and the anti-skid twisting block 15 is rotated to drive the bidirectional threaded rod 8 to rotate, thereby driving the two sliding blocks 9 to move toward each other. The movement of the sliding block 9 drives the connecting rod 11 on the bottom surface to move accordingly, thereby driving the connecting plug block 13 to be inserted into the locking hole 14 to achieve the fixation of the tapping head 3. The connecting rod 11 passes through the limiting slide groove and extends to the bottom of the sliding block 9. When the two sliding blocks 9 drive the connecting rod 11 to move, the protrusion 12 moves accordingly on the inner wall of the groove, thereby improving the stability of the movement of the connecting rod 11. When disassembling, the reverse anti-skid twisting block 15 drives the two sliding blocks 9 to move away from each other, thereby driving the connecting plug block 13 to disengage from the locking hole 14, and then the connecting block 5 is pulled out of the mounting block 4 to complete the disassembly work.
