As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0029] Please see Figure 1-6 This utility model provides a technical solution:
[0030] A spring mounting fixture includes a support frame 1. A pressure mechanism 2 is bolted to one side of the support frame 1. A placement mechanism 3 is fixedly connected to the outside of the support frame 1. A component to be installed 4 is installed inside the placement mechanism 3. A limit mechanism 5 is provided below the placement mechanism 3. The pressure mechanism 2 includes a fixed seat 21. A rotating pin 22 is installed inside the fixed seat 21. A pressure rod 23 is rotatably connected to the outside of the rotating pin 22. A connecting rod 24 is rotatably connected to one end of the pressure rod 23. A sliding sleeve 25 is fixedly connected to one side of the fixed seat 21. A sliding column 26 is slidably connected inside the sliding sleeve 25. A pressure plate 27 is fixedly connected to the lower end of the sliding column 26. The placement mechanism 3 includes a placement plate 31. A limit support column 32 is slidably connected inside the placement plate 31. A return spring 33 is fixedly connected to the bottom end of the placement plate 31. A placement groove 34 is provided inside the placement plate 31. The inner side is provided with a rounded corner 35. The inner side of the placement plate 31 is provided with a locking groove 36. The inner side of the placement plate 31 is provided with a sliding hole 37. A spring column 38 is slidably connected to the inner side of the sliding hole 37. A locking block 39 is fixedly connected to the inner side of the placement groove 34. The part to be installed 4 includes a workpiece base 41. The inner side of the workpiece base 41 is provided with a positioning groove 42. A positioning column 43 is fixedly connected to one side of the workpiece base 41. A support piece 44 is fixedly connected to the inner side of the workpiece base 41. The inner side of the workpiece base 41 is provided with a positioning groove 42. A positioning hole 46 is provided to the inner side of the workpiece base 41. The limiting mechanism 5 includes a limiting base 51. The inner side of the limiting base 51 is provided with an installation limiting groove 52. A rubber strip 53 is provided inside the installation limiting groove 52. A buffer pad 54 is glued and fixed to the bottom of the inner side of the installation limiting groove 52. A baffle 55 is fixedly connected to the inner side of the installation limiting groove 52.
[0031] As a further implementation of this solution, the central axis of the limiting support column 32 and the central axis of the return spring 33 are on the same straight line. The number of limiting support columns 32 corresponds to the number of return springs 33. There are four limiting support columns 32, which are distributed in a rectangular array in the four corner areas of the placement plate 31. The limiting support columns 32 provide stable support for the placement plate 31. At the same time, the placement plate 31 can be quickly reset by the set return springs 33, which improves the working efficiency of the device.
[0032] As a further implementation of this solution, the inner side of the placement groove 34 fits against the outer side of the workpiece base 41. Two rounded corners 35 are provided, which are symmetrically distributed at the front end of the placement groove 34. The position of the sliding hole 37 corresponds to the position of the spring column 38. The upper end of the spring column 38 is arc-shaped, and the bottom end of the spring column 38 is fixedly connected to the placement plate 31. This arrangement enables the spring column 38 to play a certain guiding role for the workpiece base 41, and the rounded corners 35 facilitate the removal of the workpiece base 41.
[0033] As a further implementation of this solution, the included angle between the rotating pin 22 and the pressure rod 23 is 90°, the pressure rod 23 is L-shaped, the included angle between the sliding column 26 and the sliding sleeve 25 is 90°, the inner side of the sliding column 26 is rotatably connected to the connecting rod 24, the sliding column 26 and the pressure plate 27 are on the same axis, the pressure plate 27 is located above the placement plate 31, the pressure plate 27 and the placement plate 31 are parallel to each other, and the pressure plate 27 and the part to be installed 4 are on the same axis. This design is conducive to the mutual transmission of force between components. The setting of the pressure rod 23 utilizes the lever principle, further saving the force required to use the device and facilitating the realization of the device effect.
[0034] As a further implementation of this solution, the upper end face of the limiting base 51 is parallel to the bottom end face of the placement plate 31. Several rubber strips 53 are provided, and the rubber strips 53 are evenly and equidistantly distributed in a ring array inside the mounting limiting groove 52. The outer side of the buffer pad 54 is in contact with the inner side of the mounting limiting groove 52. This arrangement can make the rubber strips 53 and the buffer pad 54 hinder the rotation of the spring to a certain extent, so as to avoid the situation that the installation is not in place due to the rotation of the spring.
[0035] As a further implementation of this solution, the inner side of the positioning groove 42 is fitted with the outer side of the locking block 39, the outer side of the positioning post 43 is fitted with the inner side of the locking groove 36, the inner side of the positioning hole 46 is fitted with the outer side of the spring post 38, and four support plates 44 and four positioning plates 45 are provided. The support plates 44 and the positioning plates 45 are arranged in a ring array and alternately distributed on the inner side of the workpiece base 41. This arrangement allows the support plates 44 to provide outward expansion stress for the spring and allows the positioning plates 45 to better limit the spring, thereby improving the structural strength of the spring.
[0036] Workflow: When using the spring mounting fixture, check for foreign objects inside the mounting limit groove 52. After confirming that the mounting limit groove 52 is clean, place the spring to be installed into the mounting limit groove 52 and slowly rotate the spring until one end of the spring contacts the stop plate 55 and the lower end of the spring contacts the buffer pad 54. This allows the stop plate 55 and rubber strip 53 to prevent the spring from rotating to a certain extent during installation, and allows the buffer pad 54 to absorb and mitigate vibrations from the outside or the spring itself, reducing the impact of vibration on the spring and the mounting structure, and extending the service life of the spring. Next, invert the workpiece base 41 and insert it into the placement groove 34, so that the locking block 39 is engaged in the positioning groove 42, the positioning pin 43 is engaged in the engagement groove 36, and the spring pin 38 is engaged in the positioning hole 46. The arc-shaped design of the upper end of the spring pin 38 makes it easier for the spring pin 38 to enter the positioning hole 46, and also plays a certain guiding role. At this time, hold the upper handle of the pressure rod 23 and turn it downwards. The moving pressure rod 23 moves downward, which in turn drives the sliding column 26 to slide downward inside the sliding sleeve 25 via the connecting rod 24. The downward sliding of the sliding column 26 drives the fixedly connected pressure plate 27 to move downward. When the pressure plate 27 moves a certain distance, it pushes the workpiece base 41, causing the workpiece base 41 to drive the placement plate 31 to move downward. When the workpiece base 41 moves downward a certain distance, the support plate 44 and the positioning plate 45 will accurately engage with the spring, preventing the surface of the workpiece 4 to be installed from being scratched during the installation process. At the same time, the support plate 44 provides the spring with outward expansion stress, and the positioning plate 45 limits the spring. In this way, even if the inner diameter of the spring is larger than the diameter of the installation part of the workpiece 4, the spring can still be well fixed on the workpiece 4. After the installation is completed, simply lift the pressure rod 23, and the placement plate 31 will be quickly reset by the force of the return spring 33 to restore its deformation. The rounded corner 35 makes it easy to remove the workpiece base 41 from the placement slot 34. The whole process is time-saving, labor-saving, simple and efficient.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
