DETAILED DESCRIPTION

[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0017] Embodiments of the present utility model: Figure 1 and Figure 2As shown, an auxiliary tooling for installing the camshaft of a packaging machine includes a support plate 1, a first circular hole 2 is opened at one end of the support plate 1, a flange 3 is installed on the support plate 1, 8 threaded holes 4 are opened on the flange 3, and the 8 threaded holes 4 are all threadedly connected with a top screw 5, and the top screw 5 passes through the first circular hole 2 and penetrates the support plate 1.

[0018] The support plate 1 is a rectangular plate. The main function of the support plate 1 is to install the flange 3 and the rear seat of the first wheel. The 8 threaded holes 4 on the flange 3 in this embodiment are specially customized. When the flange 3 and the rear seat of the first wheel are fixed on the support plate 1, the 8 threaded holes 4 are opposite to and coaxial with the 8 camshaft mounting holes on the first wheel, ensuring that the 8 top screws 5 can enter the 8 camshaft mounting holes respectively. The top screws are M5 top screws. The function of the top screws 5 is to limit the axial movement of the 8 camshafts, so that the camshafts are blocked by the top screws after moving to the accurate position and cannot move further, thereby improving the installation accuracy and efficiency.

[0019] In a specific embodiment, four first mounting holes 6 are provided at equal intervals around the first circular hole 2, and second mounting holes 7 are provided on the flange 3, which are opposite to the first mounting holes 6. The four first mounting holes 6 are all circular holes. In order to prevent the screw hole 4 from being misaligned with the camshaft mounting hole on the first wheel due to processing errors, the four second mounting holes 7 on the flange 3 are preferably designed as waist-shaped arc holes, so that the flange 3 can be fine-tuned to solve the processing error problem.

[0020] Furthermore, a second circular hole 8 is formed on the flange 3 , a connecting tube 9 is fixedly disposed on the flange 3 , a circular ring plate 10 is formed at one end of the connecting tube 9 away from the flange 3 , and eight guide tubes 11 are disposed on the circular ring plate 10 .

[0021] The connecting cylinder 9 is coaxial with the second circular hole 8, and the inner diameter of the connecting cylinder 9 is equal to the inner diameter of the second circular hole 8. The eight guide cylinders 11 are arranged opposite to the eight threaded holes 4. The function of the guide cylinder 11 is to provide guidance and support for the "Z"-shaped wrench 13.

[0022] Further, a hexagonal groove 12 is formed at one end of the top screw 5, and a hexagonal rod 15 is formed at one end of the "Z"-shaped spanner 13, and the hexagonal rod 15 is plugged into and matched with the hexagonal groove 12. A clamping seat 14 is fixed on the side wall of the support plate 1, and the "Z"-shaped spanner 13 is clamped and fixed on the clamping seat 14.

[0023] Working principle of the utility model: when in use, fix one end of the support plate 1 on the bench vise, make the other end of the support plate 1 at a suitable height, then place the rear seat of the No. 1 wheel on one side of the support plate 1, place the flange 3 on the other side of the support plate 1, use 4 M8 mounting bolts to pass through the second mounting hole 7 and the first mounting hole 6 respectively and connect with the threaded hole on the rear seat of the No. 1 wheel, adjust the angle of the flange 3, make the 8 top screws 5 accurately align with the 8 camshaft mounting holes on the No. 1 wheel, and then tighten the 4 M8 mounting bolts. Remove the "Z"-shaped wrench 13 from the holder 14, insert it into the 8 guide cylinders 11 in turn according to the needs to adjust the 8 top screws 5, so that the 8 top screws 5 enter the corresponding camshaft mounting holes to a suitable depth. The top screws 5 of this embodiment are marked with scales, and the staff can judge the depth of the top screws 5 according to the scales. Of course, a caliper can also be used to accurately measure the depth of the top screws 5 entering the camshaft mounting holes. After adjusting the eight top screws 5, install the camshaft from the other side of the No. 1 wheel. After the camshaft is installed to the precise position, it cannot move further due to the limitation of the top screws 5. At this time, other components can be installed.

[0024] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
