DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-Figure 4 The utility model provides a universal joint device in a tapping machine, including a shell 1, the shell 1 is the main body of the tapping machine, and a rotating block 7, a connecting block 12 and a tapping head 3 together constitute a universal joint device. The tapping head 3 rotates inside the connecting block 12 by turning the rotating block 7 up and down, so that the tapping head 3 can adapt to the tapping requirements of different positions. The outer wall of the shell 1 is fixedly connected with a fixed block 2, and the rotating block 7 can rotate up and down on the inner wall of the fixed block 2, thereby driving the tapping head 3 to rotate up and down according to the required position. The outer wall of the fixed block 2 is fixedly connected with a mounting block 4, and the inner wall of the mounting block 4 is elastically connected with a clamping block A6 through a spring A5. When the rotating block 7 is rotated to a suitable angle, the clamping block A6 pops up downward due to the elastic force of the spring A5 itself, and is clamped with the clamping slot A10 to fix the position of the rotating block 7.

[0027] Furthermore, one end of the spring A5 is fixedly connected to the inner wall of the mounting block 4, and the other end of the spring A5 is fixedly connected to the outer wall of the card block A6. The outer wall of the card block A6 is slidably connected to the inner wall of the mounting block 4. The outer wall of the card block A6 is provided with a protrusion. When the protrusion is pulled upward, the card block A6 moves upward and disengages from the slot A10, so that the rotating block 7 can be rotated. The inner wall of the fixed block 2 is rotatably connected with the rotating shaft 9. The outer wall of the rotating shaft 9 is provided with multiple groups of slots A10, and the card block A6 is engaged with the slots A10. The setting of multiple groups of slots A10 can make the rotating block 7 conveniently and quickly rotate to multiple positions and fix them, without the need to rotate the bolts for adjustment, which is more time-saving and labor-saving.

[0028] Furthermore, the outer wall of the rotating shaft 9 is fixedly connected with a rotating block 7, and the outer wall of the rotating block 7 is provided with two sets of limiting grooves 8. The limiting grooves 8 can fix the connecting block 12 on the inner wall of the rotating block 7, and the connecting block 12 can be driven to rotate synchronously by rotating the rotating block 7. The inner wall of the rotating block 7 is clamped with the connecting block 12, and the inner wall of the connecting block 12 is elastically connected with the clamping block B14 through the spring B13. When the tapping head 3 needs to be rotated, the clamping block B14 can be moved upward to make the spring B13 contract under force, and the clamping block B14 is out of contact with the clamping groove B11, so that the tapping head 3 can be rotated.

[0029] Furthermore, one end of the spring B13 is fixedly connected to the inner wall of the connecting block 12, and the other end of the spring B13 is fixedly connected to the outer wall of the clamping block B14. The outer wall of the clamping block B14 is slidably connected to the inner wall of the connecting block 12. When the tapping head 3 is rotated to a suitable angle, the spring B13 drives the clamping block B14 to pop up downward due to its own elastic force and engages with the clamping groove B11, so that the position of the tapping head 3 can be fixed to meet the tapping requirements at different positions. The inner wall of the connecting block 12 is rotatably connected to the tapping head 3, and the outer wall of the tapping head 3 is provided with multiple groups of clamping grooves B11, and the clamping block B14 is engaged with the clamping groove B11. The setting of multiple groups of clamping grooves B11 can enable the tapping head 3 to be rotated to multiple positions and fixed, which is more convenient and improves applicability.

[0030] The inner wall of the connecting block 12 is elastically connected to the limit block 15 through the spring C16. When the connecting block 12 needs to be installed, the two sets of limit blocks 15 can be pressed inward to make the limit blocks 15 move inward under force. Then, the connecting block 12 is inserted inward along the inner wall of the rotating block 7 to complete the installation. One end of the spring C16 is fixedly connected to the outer wall of the limit block 15, and the other end of the spring C16 is fixedly connected to the inner wall of the connecting block 12. The outer wall of the limit block 15 and the inner wall of the connecting block 12 are fixedly connected. Sliding connection, when the connecting block 12 moves to the position corresponding to the limit block 15 and the limit groove 8, the spring C16 drives the limit block 15 to pop outward due to its own elastic force and engages with the limit groove 8, so that the connecting block 12 can be fixed on the inner wall of the rotating block 7, and the limit block 15 is engaged with the limit groove 8. When the connecting block 12 needs to be removed, the two groups of limit blocks 15 can be pressed inward to make the limit block 15 disengage from the limit groove 8, so that the connecting block 12 can be removed conveniently and quickly.

[0031] In the utility model, during use, when it is necessary to adjust the angle of the tapping head 3, the operator can first pull up the protrusion set on the outer wall of the block A6, so that the block A6 moves upward and disengages from the slot A10, and then contacts the limit of the rotating shaft 9, and rotates the rotating block 7 up and down, and drives the tapping head 3 to rotate up and down. When the tapping head 3 is rotated to a suitable position, the spring A5 drives the block A6 to pop out downward due to its own elastic force, and engages with the slot A10, fixing the position of the rotating block 7 and the rotating shaft 9, and preliminarily fixing the position of the tapping head 3.

[0032] Then the operator can pull the block B14 upwards to disengage the block B14 from the slot B11, release the limit of the tapping head 3, and rotate the tapping head 3 inside the connecting block 12. When the tapping head 3 is rotated to a suitable position, the spring B13 drives the block B14 to pop outward due to its own elastic force and engages with the slot B11, thereby fixing the position of the tapping head 3, so that the tapping head 3 can be adapted to the tapping requirements at different positions, and there is no need to adjust the position of the tapping head 3 by rotating the bolt, which is more time-saving, labor-saving, convenient and quick.

[0033] When it is necessary to remove the tapping head 3 and the connecting block 12 for maintenance, the operator can press the two sets of limit blocks 15 to move the limit blocks 15 inward and disengage from the limit groove 8, thereby releasing the limit of the connecting block 12 and removing the connecting block 12 and the tapping head 3. When it is necessary to install the connecting block 12, the operator can first press the two sets of limit blocks 15 inward, and then insert the connecting block 12 inward along the inner wall of the rotating block 7. When the connecting block 12 moves to the position corresponding to the limit block 15 and the limit groove 8, the spring C16 drives the limit block 15 to pop out outward due to its own elastic force and engage with the limit groove 8, thereby completing the installation of the connecting block 12 and the tapping head 3. There is no need to disassemble and install by rotating the bolts multiple times, which is simple and convenient.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
