Description

Technical Field

[0001] The utility model relates to the technical field of volute clamps, in particular to a volute fixing device with adjustable angle. Background Art

[0002] The volute is the abbreviation of the volute water diversion chamber. Its appearance is very similar to a snail shell, so it is usually referred to as the volute. In order to ensure uniform water supply to the water diversion mechanism, the cross-section of the volute is gradually reduced. At the same time, it can form a necessary ring in front of the water diversion mechanism to reduce the working intensity of the water diversion mechanism.

[0003] In the mechanical processing of the volute, drilling is an indispensable process, and a fixing device is required for drilling. Since the shape of the volute is irregular, it is usually necessary to use a support plate at a specific angle and fix it on the support plate so that the position of the volute to be drilled can correspond to the upper and lower parts of the drilling machine, thereby ensuring the accuracy of the drilling machine processing. Usually, multiple holes in different positions are required on the volute, and the existing method can only replace the support plates at different angles multiple times to ensure that the hole position corresponds to the drilling machine. However, the multiple disassembly and installation of the support plates at different angles obviously have low work efficiency and high labor intensity. Utility Model Content

[0020] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0021] According to the instruction manual Figure 1-4It can be known that when the utility model is used, firstly, the fixing screw 10 is unscrewed, and the volute is buckled on the support plate 11 of the base plate 8, and the fixing screw 10 is screwed onto the threaded sleeve 9 of the support plate 11 to fix the volute on the support plate 11. This fixing method is a prior art and is well known to those skilled in the art. Then, the adjusting rod 7 is rotated by the driving member to drive the adjusting plate 12 to rotate, thereby driving the base plate 8 and the support plate 11 and the volute on the support plate 11 to rotate around the axis of the adjusting rod 7, changing the angle of the volute, and the adjusting plate 12 rotates stably in the limit opening 6. Of course, the volute can also be rotated around the axis of the fixing screw 10 by adjusting the fixing screw 10, thereby adjusting the position of the volute to be drilled, and quickly aligning the position to be drilled with the top drilling machine. The drilling machine here is not drawn, which is a prior art and is generally arranged directly above the workbench 1, which can be understood by those skilled in the art. After alignment, the lower end of the adjustment plate 12 is fixed by the fixing assembly at the bottom of the workbench 1 to ensure stability, and finally the drilling operation is performed. According to the drilling position requirements, the entire drilling operation is completed. Compared with the prior art, the utility model does not need to install the support plate 11 multiple times, but drives the adjustment plate 12 to rotate by rotating the adjustment rod 7, thereby driving the bottom plate 8 and the support plate 11 to rotate, so that the support plate 11 and the volute fixed on the support plate 11 can be adjusted in angle, so as to achieve the purpose of quickly aligning the position to be drilled with the top drilling machine, which is convenient to adjust and improves work efficiency.

[0022] Among them, the fixing assembly includes a pair of fixing plates 2 and a limiting rod 3. The pair of fixing plates 2 are arranged on the lower bottom surface of the workbench 1 and are located on both sides of the adjusting plate 12. The pair of fixing plates 2 are respectively provided with arc-shaped sliding openings 5 ​​with the axis of the adjusting rod 7 as the center of the circle. The limiting rod 3 passes through the bottom of the adjusting plate 12 and is fixedly connected to the adjusting plate 12. Both ends of the limiting rod 3 pass through the sliding opening 5 and are slidably connected to the sliding opening 5. External threads 15 are provided on both sides of the center of the limiting rod 3, and nuts 16 are screwed on the limiting rod 3 through the external threads 15.

[0023] During operation, when the adjusting rod 7 drives the adjusting plate 12 to rotate, the limiting rod 3 at the bottom of the adjusting plate 12 rotates accordingly, and slides in the sliding opening 5 of the fixed plate 2 to ensure the stability of the adjusting plate 12 during rotation. After adjusting the position, the nut 16 is screwed onto the external thread 15 of the limiting rod 3, and squeezed tightly onto the fixed plate 2, so that the limiting rod 3 is fixed to the fixed plate 2, ensuring the stability of the adjusting plate 12, thereby ensuring the stability of the support plate 11 and the volute on the support plate 11 during operation, and further ensuring the quality of drilling processing. A scale mark 17 is provided on the edge of the fixed plate 2 corresponding to the sliding opening 5, so that personnel can check the rotation angle conveniently. A reinforcing fixing strip 4 is provided between a pair of fixed plates 2. When the nut 16 is fixed, the strength between the fixed plates 2 is increased to avoid breaking with the bottom of the workbench 1.

[0024] The driving member is a motor 13, which drives the adjusting rod 7 to rotate electrically, which is easy and labor-saving. Of course, manual adjustment can also be performed by a handle.

[0025] 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.
