DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0021] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0022] Example 1:

[0023] Combine Figure 1-4 As shown, this embodiment provides a servo tailstock eccentric mechanism, including: a main body mechanism 100.

[0024] Among them, the main mechanism 100 includes a servo motor body 110, a shell 120 fixed on one side of the servo motor body 110, a fixed shaft 130 arranged in the inner cavity of the shell 120 and fixedly connected to the axis of the servo motor body 110 at one end and extending out of the shell 120 at the other end, a first eccentric block 140 fixedly sleeved on the fixed shaft 130, a second eccentric block 150 rotatably sleeved on the fixed shaft 130, and a locking member 160 installed on the end of the fixed shaft 130.

[0025] The servo motor body 110 is used to drive the eccentric block to rotate, and vibration is generated by the rotation of the eccentric block. The shell 120 is fixed to the servo motor body 110 by bolts, and is used to provide protection for the first eccentric block 140 and the second eccentric block 150 to prevent dust, oil, etc. from adhering to their surfaces and causing corrosion.

[0026] The fixed shaft 130 is used to install the first eccentric mass 140 and the second eccentric mass 150. A bearing 122 is fixed in the middle of the housing 120. The fixed shaft 130 includes a circular shaft 131 with one end fixedly connected to the shaft of the servo motor body 110 and the other end fixed to the inner ring of the bearing 122, and a limiting ring 132 symmetrically fixed on the outer side of the circular shaft 131. Grooves 1311 are provided on both sides of the circular shaft 131. The shaft of the servo motor body 110 extends into the groove 1311 on one side of the circular shaft 131, and the circular shaft 131 is fixedly connected to the shaft of the servo motor body 110 by bolts to ensure that when the shaft of the servo motor body 110 rotates, the circular shaft 131 can be driven to rotate synchronously. The limiting ring 132 is used to limit the second eccentric mass 150 to prevent the second eccentric mass 150 from moving axially after losing the locking member 160.

[0027] The first eccentric block 140 is fixedly sleeved on the circular shaft 131, and the first eccentric block 140 is rotatably sleeved on the circular shaft 131, and is between the first eccentric block 140 and the limiting ring 132 on one side, and a first plug hole 1321 is opened in a circular array on the limiting ring 132, a second plug hole 141 is opened in a circular array in the middle of the first eccentric block 140, and a third plug hole 151 is opened in a circular array in the middle of the second eccentric block 150, so that the locking piece 160 can lock the three together.

[0028] The locking member 160 includes a base plate 161 provided at the end of the fixed shaft 130, an insertion rod 162 fixed to the base plate 161 in an annular array and passing through the fixed shaft 130, the first eccentric block 140 and the second eccentric block 150, a spring 163 connecting the base plate 161 and the inner wall of the fixed shaft 130, a pull ring 164 fixed to one side of the base plate 161, and an indicator pin 165 fixed to the base plate 161. An arc-shaped scale 121 is fixed to one side of the housing 120, and the base plate 161 is used to fix the insertion rod 162, and drives the insertion rod 162 to move, the insertion rod 162 is movably engaged in the first hole 1321, the second hole 141, and the third hole 151, locking the fixed shaft 130, the first eccentric block 140, and the second eccentric block 150 together, one end of the spring 163 is fixed to the bottom plate 161, and the other end is fixed to the inner bottom wall of the groove 1311 at one end of the circular shaft 131, ensuring the stability of the insertion rod 162, and the pulling plate makes it convenient for the user to pull the bottom plate 161 to move, thereby driving the insertion rod 162 to move.

[0029] An arc-shaped scale 121 is fixed on one side of the housing 120, which cooperates with the indicator needle 165 on the base plate 161. When the base plate 161 is rotated, the insertion rod 162 is driven to rotate, and the rotation of the insertion rod 162 drives the fixed shaft 130 to rotate, that is, the first eccentric block 140 fixedly sleeved on the fixed shaft 130 is driven to rotate, thereby adjusting the angle between the first eccentric block 140 and the second eccentric block 150. When adjusting, the worker observes the degree marked by the indicator needle 165 on the arc-shaped scale 121 to accurately adjust the angle between the first eccentric block 140 and the second eccentric block 150.

[0030] The working principle and use process of the present invention are as follows: when it is necessary to adjust the amplitude of the servo motor body 110, the pull ring 164 is pulled outward, and the insertion rod 162 is driven to move outward through the bottom plate 161, so that the end of the insertion rod 162 is retracted from the third insertion hole 151 on the second eccentric block 150 to the second insertion hole 141 on the first eccentric block 140. At this time, the second eccentric block 150 loses its lock, and the pull ring 164 is rotated to drive the insertion rod 162 to rotate through the bottom plate 161. The rotation of the insertion rod 162 drives the fixed shaft 130 to rotate, that is, drives the first fixed sleeve on the fixed shaft 130 to rotate. The eccentric mass 140 rotates to adjust the angle between the first eccentric mass 140 and the second eccentric mass 150. The worker observes the degree marked by the indicator needle 165 on the arc scale 121 during adjustment. When the indicator needle 165 rotates to the target angle, the pull ring 164 is released. At this time, under the action of the spring 163, the base plate 161 is driven to close to the end of the fixed shaft 130. The base plate 161 is reset to drive the insertion rod 162 to be reinserted into the third socket 151 on the second eccentric mass 150, locking the first eccentric mass 140 and the second eccentric mass 150 together, and the adjustment of the eccentric mass angle can be completed.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
