Description

Technical Field

[0001] The invention relates to a rotary clamp, in particular to a quick-installation rotary clamp and a rotary clamp installation process based thereon. Background Art

[0002] like Figure 1 As shown, the rotating fixture includes: a first supporting seat 1, a second supporting seat 2, a first rotating shaft 3, a second rotating shaft 4, a first connecting block 5, a second connecting block 6, a product fixture 7, a rotating drive mechanism 8 and a connecting mechanism 9. The first supporting seat 1 is provided with a first rotating shaft 3 capable of rotating, the second supporting seat 2 is provided with a second rotating shaft 4 capable of rotating, the first connecting block 5 is fixed to the first rotating shaft 3, the second rotating shaft 4 is connected to the second connecting block 6, one end of the first connecting block 5 is connected to one end of the product fixture 7, and the second connecting block 6 is connected to the other end of the product fixture 7. The rotating drive mechanism 8 is used for driving the first rotating shaft 3 and the second rotating shaft 4 to rotate, and the first rotating shaft 3 and the second rotating shaft 4 are on a rotating axis 30.

[0003] The connecting mechanism 9 includes: a cylindrical pin 91, a diamond pin 96, a first screw connection group 94 and a second screw connection group 95. The product fixture 7 is symmetrical along the center plane of symmetry 70. A first positioning point is set at one end of the product fixture 7, and a second positioning point is set at the other end of the product fixture 7. The first positioning point is for the cylindrical pin 91 to pass through and then be inserted into the first connecting block 5, and the second positioning point is for the diamond pin 96 to pass through and then be inserted into the second connecting block 6. During installation, the cylindrical pin 91 is inserted first, and then the diamond pin 96 is inserted. Subsequently, the first screw connection group 94 is used to connect the product fixture 7 to the first connecting block 5, and the second screw connection group 95 is used to connect the product fixture 7 to the second connecting block 6.

[0004] During the installation of the product fixture 7, the cylindrical pin 91 and the diamond pin 96 are first used to position the product fixture 7 on the first connecting block 5 and the second connecting block 6. In terms of design concept, the line between the cylindrical pin 91 and the diamond pin 96 is located on the symmetry center plane 70. However, after production and processing, the line between the cylindrical pin 91 and the diamond pin 96 will deviate from the symmetry center plane 70, so it is difficult to align the rotating axis 30 on the symmetry center plane 70. If it is not aligned, the loads on both sides of the rotating axis 30 are different during rotation, which can easily cause damage to the first rotating axis 3 and the second rotating axis 4, resulting in a shorter service life of the entire rotating fixture. Summary of the invention

[0005] The present invention aims to provide a quick-installation rotary clamp and a rotary clamp installation process based thereon, so as to solve the problem in the prior art that it is difficult to make the rotary axis on the symmetrical center plane of the product clamp by using cylindrical pins and diamond pins.

[0006] To achieve the above object, the present invention adopts the following technical solutions: The present invention firstly discloses a quick-installation rotating fixture, comprising: a first supporting seat, a second supporting seat, a first rotating shaft, a second rotating shaft, a first connecting block, a second connecting block, a product fixture, a rotating driving mechanism and a connecting mechanism, wherein a first rotating shaft capable of rotation is installed on the first supporting seat, a second rotating shaft capable of rotation is installed on the second supporting seat, a first connecting block is fixed on the first rotating shaft, a second rotating shaft is connected to the second connecting block, one end of the first connecting block is connected to one end of the product fixture, and the second connecting block is connected to the other end of the product fixture, and the rotating driving mechanism is used for driving the first rotating shaft and the second rotating shaft to rotate, and the first rotating shaft and the second rotating shaft are on a rotating orbit; The connection mechanism includes: a cylindrical pin, a positioning seat, an alignment positioning mechanism, a first screw connection group and a second screw connection group. The cylindrical pin is inserted into the center of one end of the product fixture and the first connection block. The positioning seat is relatively fixed to the second connection block. The alignment positioning mechanism located next to the other end of the product fixture is installed on the positioning seat. The alignment positioning mechanism is used to make the rotation around the line on the symmetrical center plane of the product fixture. The end of the product fixture where the cylindrical pin is located is connected to the first connection block through a first screw connection group, and the end of the product fixture located next to the alignment and positioning mechanism is connected to the second connection block through a second screw connection group.

[0007] Preferably, the alignment and positioning mechanism includes: a positioning bolt, a positioning screw hole is opened at the end of the product fixture next to the alignment and positioning mechanism, the positioning screw hole is perpendicular to the symmetry center, the positioning bolt is threadedly connected to the positioning block, and the positioning bolt is threadedly connected to the positioning screw hole.

[0008] Preferably, the positioning block is connected to the second connecting block via fixing bolts.

[0009] Preferably, the first connecting block and the second connecting block are both symmetrically arranged along the rotation line.

[0010] The present invention also discloses a rotating fixture installation process, which is implemented based on the quick-install rotating fixture as described above; The rotating fixture installation process comprises the following steps: S1, prepare the first support base, the second support base, the first rotating shaft, the second rotating shaft, the first connecting block, the second connecting block and the rotating drive mechanism which have been assembled with each other; S2, moving the product fixture to one end of the first connecting block and one end of the second connecting block; S3, insert a cylindrical pin into the center of one end of the product fixture and the first connecting block; S4, adjusting the product fixture to rotate around the axis of the cylindrical pin so that the rotation axis where the first rotation axis and the second rotation axis are located is on the symmetry center plane of the product fixture; S5. Adjust the alignment and positioning mechanism to position the product fixture, and keep the rotation axis on the symmetrical center plane of the product fixture; S6. Use a first screw connection group to connect the end of the product fixture where the cylindrical pin is located to the first connection block, and use a second screw connection group to connect the end of the product fixture located next to the alignment and positioning mechanism to the second connection block.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this application, the cylindrical pin and diamond pin of the prior art are no longer used to locate the symmetry center plane in the product fixture. Since the cylindrical pin opening, diamond pin opening, cylindrical pin size and diamond pin size on the product fixture will affect the relative position of the product fixture and the rotation around the line, the processing difficulty is very large, and the relative position of the symmetry center plane and the rotation around the line in the product fixture cannot be adjusted during installation. Therefore, in this application, a cylindrical pin is used to first locate the center of one end of the product fixture, and then the product fixture is adjusted to rotate around the rotation around the line, so as to rotate to the position where the symmetry center plane in the product fixture and the rotation around the line are on the same plane. After adjustment, the alignment positioning mechanism is used to locate the symmetry center plane in the product fixture and the rotation around the line on the same plane, so as to ensure the alignment effect, avoid the asymmetry of the weight of the product fixture on both sides of the rotation around the line during rotation, avoid the first rotation axis and the second rotation axis being easily worn due to misalignment, and extend the service life of the entire quick-installation rotary fixture. At the same time, it will not cause the installation efficiency of the entire quick-installation rotary fixture to decrease, which not only ensures the accuracy after installation, but also achieves the requirement of quick installation.

[0012] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
