Description

Technical Field

[0002] As we all know, servo drive technology, as one of the key technologies for CNC machine tools, industrial robots, and other industrial machinery control, has received widespread attention both at home and abroad. In the last decade of the 20th century, the development of microprocessor technology, power electronics technology, network technology, and control technology laid a good foundation for the further development of servo drive technology. However, existing pump sets usually require the use of bolts to fix them during installation. Therefore, with long-term use, the bolts will corrode and rust due to air and dust, and then the bolts will break or loosen, causing the pump set to lose its fixing ability, thereby affecting its normal use. At the same time, after the bolts are rusted or corroded, they are difficult to remove. Therefore, when the pump set needs to be repaired, it becomes extremely troublesome and time-consuming, which increases the difficulty of maintenance.

[0003] A search revealed a servo hydraulic station disclosed in a Chinese patent application (Application No. CN202322690851.0). The motor mounting structure of this servo hydraulic station includes a horizontal support platform and a pump assembly. The pump assembly is movably mounted on the upper surface of the horizontal support platform. Fixed plates are fixedly connected to the left and right sides of the pump assembly. Two sets of support plates are mounted on the top of the horizontal support platform. The fixed plates fit into the support plates, and a movable block is movably mounted within the movable groove.

Now, to address this problem, another method is proposed to realize the installation of the pump group and the horizontal support platform. Utility Model Content

Several universal wheel bodies 2 are fixed on the surface of the servo hydraulic station body 1. A working groove 4 is opened in the inner cavity of the servo hydraulic station body 1. A power motor 5 is fixed on the surface of the working groove 4. The surface of the power motor 5 is provided with a clamping mechanism 6 for clamping the motor body 3. The surface of the clamping mechanism 6 is provided with a transmission mechanism 7 for limiting the motor body 3. The surface of the transmission mechanism 7 is provided with a ball 8. An auxiliary mechanism 9 is provided on one side of the surface of the transmission mechanism 7. When the motor body 3 is installed in the utility model, the staff first places the motor body 3 in the working area of ​​the clamping mechanism 6, and then uses the power motor 5 to drive the clamping mechanism 6 to clamp the motor body 3 in the horizontal direction. During the operation of the clamping mechanism 6, under the action of the transmission mechanism 7, the ball 8 and the auxiliary mechanism 9, the motor body 3 is pressed in the vertical direction, thereby achieving the purpose of installing the motor body 3.

[0022] The power motor 5 is a servo motor and has a built-in brake device. In this embodiment, through this setting, the accuracy of the power motor 5 during operation is improved under the action of the servo motor. In addition, under the action of the brake device, the output shaft of the power motor 5 can be stably stopped.

[0023] The clamping mechanism 6 includes a rotating shaft 61 driven by bevel gears and the output shaft of the power motor 5. Threaded bodies 62 are provided on both sides of the surface of the rotating shaft 61. The surface of the threaded body 62 is engaged with a clamping block 63. The surface of the clamping block 63 is fixed with an extension block 64. In this embodiment, through the arrangement of the rotating shaft 61, the threaded body 62, the clamping block 63 and the extension block 64, when the power motor 5 is working, the rotating shaft 61 can be rotated under the action of the bevel gear, and the threaded bodies 62 provided on both sides of the surface of the rotating shaft 61 can be engaged with the clamping block 63, so that the extension block 64 and the clamping block 63 can clamp the machine foot of the motor body 3.

[0024] The thread lead angle of the threaded bodies 62 on both sides is smaller than the equivalent friction angle, and the threaded bodies 62 on both sides have the same specifications but opposite directions. In this embodiment, through this setting, the threaded body 62 has self-locking properties, and under the setting of the specifications of the threaded body 62, the clamping blocks 63 on both sides move in opposite directions but have the same displacement.

[0025] The transmission mechanism 7 includes a first piston tube 73 that slides in the inner cavity of the clamping block 63, and a first piston block 72 is slidably provided in the inner cavity of the first piston tube 73. A force-bearing rod 71 is fixed to one side of the surface of the first piston block 72. The other end of the first piston tube 73 is connected to a connecting tube 74, and the other end of the connecting tube 74 is connected to a second piston tube 75. The second piston tube 75 is provided in the inner cavity of the extension block 64, and the inner cavity of the second piston tube 75 is connected to a second piston block 76. The ball 8 is fixed to one side of the second piston block 76. In this embodiment, the force-bearing rod 71, the first piston block 72, the first piston tube 73, the connecting tube 74, the second piston tube 75 and the second piston block 76 are arranged so that when the clamping blocks 63 on both sides move the machine feet of the motor body 3, the force-bearing rod 71 can be squeezed under the action of the machine feet, and then under the action of the first piston block 72, the pressure in the inner cavity of the first piston tube 73 changes, and then under the action of the connecting tube 74, the second piston block 76 drives the ball 8 to move, and then under the action of the ball 8, the machine feet of the motor body 3 are pressed.

[0026] The auxiliary mechanism 9 includes a fixed block 91 fixed to one side of the surface of the first piston tube 73. Both sides of the surface of the fixed block 91 are slidably provided with a limit shaft 93. The other end of the limit shaft 93 is fixed to the surface of the clamping block 63. The surface of the limit shaft 93 is sleeved with a spring 92. One end of the spring 92 is fixed to the surface of the clamping block 63, and the other end of the spring 92 is fixed to the surface of the fixed block 91. In this embodiment, by setting the fixed block 91, the spring 92 and the limit shaft 93, when the ball 8 acts on the motor body 3, the force rod 71 The first piston tube 73 can be pushed to move in the clamping block 63, and with the assistance of the fixed block 91, the spring 92 and the limiting shaft 93, the first piston tube 73 is provided with limiting and supporting force. When the force rod 71 can slide relative to the first piston tube 73, the position of the first piston tube 73 can be supported under the action of the spring 92. When the force rod 71 is stationary and squeezed relative to the first piston tube 73, the first piston tube 73 can move under the action of the fixed block 91, the spring 92 and the first piston tube 73.

[0027] Working principle: When in use, if the motor body 3 needs to be fixed to the surface of the servo hydraulic station body 1, the staff first places the motor body 3 on the surface of the servo hydraulic station body 1, and then uses the power motor 5. Under the action of the power motor 5, the rotating shaft 61, the threaded body 62, the clamping block 63 and the extension block 64 are moved. The machine foot of the motor body 3 can be clamped by the clamping block 63 and the extension block 64. In addition, the force rod 71 arranged in the inner cavity of the clamping block 63 first contacts the machine foot of the motor body 3, and the force rod 71 drives the first piston block 72 in the inner cavity of the first piston tube 73 Slide, and then under the action of the connecting tube 74, the second piston block 76 in the inner cavity of the second piston tube 75 moves. After the ball 8 fits the surface of the machine foot of the motor body 3, the second piston block 76 cannot move, and then under the action of pressure, the first piston tube 73 slides in the inner cavity of the clamping block 63, and with the assistance of the fixing block 91, the spring 92 and the limiting shaft 93, the stability of the first piston tube 73 during movement is improved. After the clamping blocks 63 on both sides completely clamp the machine foot of the motor body 3, the motor body 3 can be fixed and installed under the action of the ball 8 and the clamping block 63.
