A multi-station grinding machine fine adjustment mechanism is disclosed, referring to fig. 1, and comprises a small bottom plate 21 capable of sliding along an X axis and a Y axis and a driving part 22 for driving the small bottom plate 21 to slide along the X axis and the Y axis, wherein a measuring part 23 is arranged on the small bottom plate 21, and a workpiece clamping part 24 is arranged on the measuring part 23; the device also comprises a control module, and the measuring part 23 and the driving part 22 are respectively electrically connected with the control module. In addition, the large bottom plate 1 is also provided with a protective cover 11, and a driving structure for driving the whole structure above the large bottom plate 1 to slide along the X axis and the Y axis is arranged below the large bottom plate 1.
Before the workpiece is polished, the workpiece is fed back to the control module through the measuring part 23 when being polished, and then the control module regulates and controls the driving part 22 to give an instruction for compensation, so that the position of a corrected product is achieved, and the consistency of multi-station output is ensured. The measuring part 23 is matched with the driving part 22 for use, and workpieces can overcome error factors to achieve consistency; the multi-station grinding and polishing machine has the advantages of being capable of independently and simultaneously working at multiple stations, reducing energy consumption, reducing precision errors of all stations of multi-station grinding and polishing equipment, enabling grinding and polishing quality to be higher, and being high in good machining precision, high in product consistency, low in machining cost, low in assembly cost and high in production efficiency.
In the present embodiment, the measuring unit 23 is a force control sensor. The force control sensor ensures that the forces applied to the workpieces during polishing are equal by detecting the micro-movement of the workpiece clamping part 24, and indirectly ensures that the distances between the workpieces and the grinding disc are the same; in addition, the force-controlled sensor can actively realize small compensation for small displacements (several millimeters) in the X-axis, Y-axis and Z-axis.
The force control sensor is used for measuring the reaction force when the workpiece is in contact with the grinding disc, the control module calculates the reaction force, the reaction force is converted into the number of turns of the rotation of the motor, and the motor drives the small bottom plate 21 to move forwards or backwards slightly, so that the size of the reaction force is changed, and the reaction force is stabilized in a set range. The force is stabilized in the set range, the grinding amount of grinding workpieces of all stations can be guaranteed to be the same, the grinding amount is the same, and finally products obtained by grinding have high consistency.
Of course, the measuring part 23 may be a distance sensor according to actual conditions. The distance sensor dynamically detects the distance deviation of the workpiece relative to the grinding disc during grinding, dynamically and automatically inputs a corrected numerical value, and independently moves the workpiece clamping part 24 to ensure that the distance of the workpiece relative to the grinding disc is equal.
In addition to the force control sensor and the distance sensor, the workpiece clamping portion 24 can be moved independently by manually measuring the height difference of each grinding disc and inputting a correction value, thereby ensuring that the distance of the workpiece relative to the grinding disc is equal.
In this embodiment, the small bottom plate 21 is provided with a sliding block at the bottom, and the large bottom plate 1 is provided with a sliding groove for sliding the sliding block.
Specifically, the workpiece clamping portion 24 includes an installation seat 241 installed on the measuring portion 23, a rotary table mechanism 242 is installed on the installation seat 241, a hollow rotary output shaft 243 is connected to the upper end of the rotary table mechanism 242 in a rotating mode, a motor 244 used for driving the hollow rotary output shaft 243 to rotate is installed on one side of the rotary table mechanism 242, an air cylinder 245 is installed on the hollow rotary output shaft 243, and a jig clamping member 246 penetrating through a jig is installed on an output shaft of the air cylinder 245. The motor 244 is a servo motor, a stepper motor, or a linear motor.
Of course, depending on the actual situation, the workpiece may be clamped by the air cylinder 245, and a magnet-attraction or vacuum-attraction manner may be adopted.
In the present embodiment, the turntable mechanism 242 is a divider. Of course, a speed reducer or a DD motor may be used according to the actual situation.
Specifically, the driving portion 22 is a screw mechanism driven by a motor. The motor is a servo motor, a stepping motor or a linear motor.
