[0003] Therefore, this application provides a vibration motor counterweight anti-loosening component based on an elastic preload mechanism to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a counterweight anti-loosening component for a vibratory motor based on an elastic pre-tightening mechanism, which aims to solve the problem that the fixing bolts may loosen due to vibration in the long-term high-frequency vibration working environment of the vibratory motor, resulting in the failure of the connection between the eccentric cam and the counterweight, thereby affecting the normal operation of the equipment, or even causing equipment damage or safety accidents.

[0005] To achieve the above objectives, this application provides the following technical solution: a vibration motor counterweight anti-loosening component based on an elastic pre-tightening mechanism, comprising a vibration motor, with an eccentric cam and a counterweight connected to both ends of the vibration motor via a rotating shaft.

Both the eccentric cam and the counterweight are provided with fixing holes for installing the fixing bolts, and multiple sets of fixing holes are provided. Protective covers for protecting the eccentric cam and the counterweight are connected to both ends of the vibration motor. The protective covers are provided with an anti-loosening component for pre-tightening the counterweight, effectively preventing the fixing bolts from loosening and improving connection reliability.

The mounting plate has a through hole adapted to the bearing seat and a limiting hole adapted to the fixing hole. The pre-tightening mechanism is installed in the limiting hole, which enhances the stability of the anti-loosening assembly connection.

[0008] Preferably, the limiting holes are provided in six sets, of which five sets of the limiting holes are connected to the pre-tightening mechanism, and the sixth set of the limiting holes is used to connect the limiting rod, thereby improving the reliability and applicability of the anti-loosening mechanism.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] refer to Figure 1-4 The vibratory motor counterweight anti-loosening component based on an elastic preload mechanism is shown. It includes a vibratory motor 1, with eccentric cams 4 and counterweights 5 connected to both ends of the motor via shafts. The counterweights 5 are fixed to the eccentric cams 4 by fixing bolts 6. Both the eccentric cams 4 and the counterweights 5 have fixing holes for mounting the fixing bolts 6, with three sets of holes. The fixing bolts 6 are hexagonal socket head cap screws. Protective covers 2 are also provided on both sides of the motor to protect the eccentric cams 4 and counterweights 5. To prevent the fixing bolts 6 connecting the eccentric cams 4 and counterweights 5 from loosening due to vibration during equipment operation, an anti-loosening component 3 is provided inside the protective cover 2. An elastic telescopic rod 22 is connected to the base plate 21 of the protective cover 2. The telescopic end of the elastic telescopic rod 22 is connected to a bearing seat 23. The anti-loosening component 3 is connected to the bearing seat 23 so that when the counterweight 5 rotates, the anti-loosening component 3 rotates synchronously. At the same time, in order to more easily fix the anti-loosening component 3, three sets of pressure plates 24 are connected to the bearing seat 23, and one set of pressure plates 24 is connected to a limiting rod 25 for fixing the anti-loosening component 3. The anti-loosening component 3 also includes a mounting plate 31. The mounting plate 31 has through holes adapted to the bearing seat 23 and six sets of limiting holes 39. Five sets of limiting holes 39 are connected to a pre-tightening mechanism 38, and the sixth set of limiting holes 39 is used to connect the limiting rod 25. The position of the limiting hole 39 is adapted to the fixing hole, so that even if the equipment changes due to changes in usage requirements and the position of the eccentric cam 4 and the counterweight 5 is adjusted, the fixing bolt 6 can still be protected against loosening by the pre-tightening mechanism 38.

[0022] As one embodiment of this invention, to better protect the fixing bolt 6 from loosening, the pre-tightening mechanism 38 further includes a mounting block 33 and an anti-loosening pressure block 37. The mounting block 33 is installed in the limiting hole 39. A mounting groove 32 is provided on the mounting block 33, and an anti-loosening spring 35 and a sliding sleeve 36 are provided within the mounting groove 32. The anti-loosening spring 35 is positioned between the mounting plate 31 and the sliding sleeve 36. The inner diameter of the sliding sleeve 36 is smaller than the size of the anti-loosening pressure block 37. A spiral guide rod 34 for installing the anti-loosening pressure block 37 is connected to the mounting block 33. The anti-loosening pressure block 37 slides on the spiral guide rod 34. The anti-loosening pressure block 37 has a portion that corresponds to the spiral guide rod 34. The spiral guide rod 34 is fitted with a cylindrical positioning block 7 that is compatible with the fixing bolt 6. The size of the cylindrical positioning block 7 is the same as the inscribed circle of the internal hexagonal groove of the fixing bolt 6. In use, the cylindrical positioning block 7 on the spiral guide rod 34 is inserted into the internal hexagonal groove of the fixing bolt 6, so that the anti-loosening pressure block 37 contacts the fixing bolt 6. Under the action of friction, the fixing bolt 6 is initially prevented from loosening. At the same time, the anti-loosening spring 35 pushes the anti-loosening pressure block 37 to rotate and move on the spiral guide rod 34 through the sliding sleeve 36, so that the anti-loosening pressure block 37 presses against the fixing bolt 6 and applies a pre-tightening force to the fixing bolt 6, further improving the anti-loosening effect of the component on the fixing bolt 6.

[0023] The working principle of this utility model is as follows: First, the operator adjusts the eccentric cam 4 and counterweight 5 on the vibratory motor 1 to the required positions. Then, the eccentric cam 4 is connected to the counterweight 5 using fixing bolts 6. Next, the operator assembles the corresponding pre-tightening mechanism 38 on the anti-loosening component 3 according to the position of the fixing bolts 6. The anti-loosening spring 35 and sliding sleeve 36 in the pre-tightening mechanism 38 are installed in the mounting groove 32 on the mounting block 33 in sequence. Then, the anti-loosening pressure block 37 is installed on the spiral guide rod 34. Finally, the operator assembles the pre-tightening mechanism 38. Align the cylindrical positioning block 7 on the spiral guide rod 34 with the fixing bolt 6, install the anti-loosening component 3 onto the counterweight block 5, and simultaneously position the cylindrical positioning block 7 in the fixing bolt 6 so that the fixing bolt 6 contacts the anti-loosening pressure block 37. Then, align the bearing seat 23 and the limiting rod 25 connected to the bottom plate 21 in the protective cover 2 with the through hole and the limiting hole 39 on the mounting plate 31, respectively, and install the protective cover 2 onto the vibration motor 1. The elastic telescopic rod 22 connected to the bottom plate 21 pushes the anti-loosening component 3 through the pressure plate 24, making the connection between the anti-loosening component 3 and the vibration motor 1 more secure.
