Description

Technical Field

[0001] This utility model relates to the technical field of rapid positioning device for eccentric blocks of vibrating motors, and in particular to a rapid positioning device for eccentric blocks of vibrating motors with angular scale markings. Background Technology

[0002] In traditional methods for adjusting the angle of the eccentric block of a vibratory motor, one approach is to pre-set several fixed-angle positioning holes on the eccentric block to achieve rapid positioning. However, this method can only provide a limited number of fixed angles and cannot achieve stepless or more precise angle adjustment.

[0003] When fine adjustments of non-preset angles are required, traditional adjustment methods mainly rely on manual operation, which requires repeated disassembly and reassembly of the protective cover and multiple measurements using tools such as protractors. This results in low adjustment efficiency, poor accuracy, and cumbersome operation. Adjusting the eccentric blocks on both sides of the vibratory motor requires multiple measurements and adjustments. Therefore, this application provides a rapid positioning device for the eccentric blocks of a vibratory motor with angle scale markings to meet the requirements. Utility Model Content

[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 1-4The diagram illustrates a rapid positioning device for an eccentric block of a vibratory motor with angular scale markings. It includes a vibratory motor 1 and a positioning device 5. Eccentric blocks 4 are connected to both ends of the vibratory motor 1. The vibratory motor 1 also has a protective cover 2 for protecting the eccentric blocks 4. Threaded holes 3 are provided on the vibratory motor 1 for installing the protective cover 2. The positioning device 5 is used to position the adjustment angle of the eccentric blocks 4. To enable faster adjustment of the eccentric blocks 4 of the vibratory motor 1, the positioning device 5 also includes a base plate 6, a fixing rod 7, and a positioning plate 8. The fixing rod 7 is used to fix the base plate 6 to the vibratory motor 1. The positioning device 5 is slidably connected to the base plate 6, and a positioning plate 8 for rapid positioning is rotatably connected to the base plate 6. There are four sets of positioning plates 8. The base plate 6 also includes an inner plate 61 and an outer ring plate 62. The outer ring plate 62 is connected to the inner plate 61 through connecting rods 63. There are three sets of connecting rods 63, each set being 120 degrees apart. Angle scale markings are set on the inner plate 61. A positioning rod 9 for mounting the positioning plate 8 is connected to the inner plate 61. The connecting rods 63 have mounting holes 64 for mounting the fixing rod 7. There are four sets of mounting holes 64. The mounting holes 64 correspond to the positions of the threaded holes 3, so that the positioning device 5 does not require additional adjustment. The position of the positioning plate 8 can be determined by simply adjusting the position of the fixing rod 7 in the mounting hole 64. This allows for a single measurement to determine the required angle of the eccentric blocks 4 on both sides of the vibratory motor 1. Four sets of fixing rods 7 are provided, and their positions are matched to the threaded holes 3, facilitating the connection of the positioning device 5 to the vibratory motor 1. The positioning plate 8 has a measuring hole 81, a positioning hole 82, and an observation hole 83. The size of the positioning hole 82 matches the positioning rod 9, and the observation hole 83 corresponds to the position of the angle scale markings. The observation hole 83 is positioned between the measuring hole 81 and the positioning hole 82. Through the observation hole 83, and with the positioning device... The device 5 also includes a stop bar that matches the size of the measuring hole 81. There are two sets of stop bars. When the positioning plate 8 is adjusted to the required position, the stop bar can be inserted into the measuring hole 81 in the positioning plate 8. This allows the positioning reference to be adjusted by the stop bar when adjusting the position of the eccentric block 4. In order to fix the position of the positioning plate 8 after the angle adjustment, positioning rods 9 are provided on both sides of the inner plate 61. Each pair of four sets of positioning plates 8 is a pair. A pair of positioning plates 8 is installed on the positioning rods 9 on both sides of the inner plate 61. The positioning rods 9 are threaded for installing the fixing nuts 91. The fixing nuts 91 are engaged on the positioning rods 9.

[0022] As one embodiment of this invention, in order to enable the positioning device 5 to be quickly disassembled from the vibration motor 1, the two ends of the fixing rod 7 are provided with threaded sections 71 that are compatible with the threaded holes 3, and the two ends of the fixing rod 7 are provided with limiting nuts 72 for limiting the position.

[0023] The working principle of this utility model is as follows: First, remove the protective cover 2 from the threaded hole 3 on the vibratory motor 1. Then, install the positioning device 5 onto the vibratory motor 1. Install the four sets of fixing rods 7 in the positioning device 5 onto the vibratory motor 1. One end of the fixing rod 7 is inserted into the threaded hole 3 through the threaded section 71. Then, remove the limiting nut 72 on the other end of the fixing rod 7. Next, align the mounting hole 64 on the outer ring plate 62 of the base plate 6 with the fixing rod 7. Then, install the base plate 6 onto the fixing rod 7. Simultaneously, make the positioning rod 9 connected to the inner plate 61 abut against the rotating shaft of the vibratory motor 1. Then, through the limiting nut 7... 2. Fix the base plate 6 to the fixing rod 7. Then, first adjust the pair of positioning plates 8 on the front side of the inner plate 61 that are farther away from the vibration motor 1. Observe the angle scale markings on the inner plate 61 through the observation hole 83 on the positioning plate 8 to adjust the included angle between the two sets of positioning plates 8 on the same side of the inner plate 61. After adjustment, fix the position of the two sets of positioning plates 8 by rotating the fixing nut 91 on the positioning rod 9 on the same side as the two sets of positioning plates 8. Then, adjust the pair of positioning plates 8 on the other side of the inner plate 61 to approximately the same position as the pair of positioning plates 8 on the front side. Finally, insert the stop rod into the measuring hole 81 in the positioning plate 8. Connect the positioning plates 8 on both sides of the inner plate 61 so that the position of the positioning plate 8 on the rear side of the inner plate 61 is fixed and the stop rod is positioned above the eccentric block 4. Then, the operator can adjust the included angle between the two sets of eccentric blocks 4 on the same side of the vibration motor 1 with the position of the stop rod as a reference. After the adjustment is completed, first rotate the limiting nut 72 at the end of the fixing rod 7 that is farther away from the vibration motor 1 in the opposite direction. Then rotate the fixing rod 7 so that the fixing rod 7 is removed from the threaded hole 3 on the vibration motor 1. Then slide the fixing rod 7 in the mounting hole 64 so that the limiting nut 72 at the other end of the fixing rod 7 is aligned with the base plate 6. The outer ring plate 62 of the device is in contact with the device. Then, the positioning device 5 is moved to the eccentric block 4 at the other end of the vibration motor 1. The positioning device 5 is then fixed to the vibration motor 1 by the fixing rod 7. The base plate 6 is then fixed to the fixing rod 7 by the limiting nut 72. There is no need to adjust the position of the positioning plate 8. The angle of the eccentric block 4 of the vibration motor 1 can be adjusted by simply moving the stop bar above the eccentric block 4, which improves the positioning efficiency. After the positioning adjustment of the eccentric block 4 is completed, the positioning device 5 is removed from the vibration motor 1. After the protective cover 2 is installed on the vibration motor 1, it can be used normally.
