Description

Technical Field

[0001] The invention relates to the technical field of polishing lenses with a polishing machine, and more specifically, to a detection method for a fine grinding polishing machine. Background Art

[0002] The lens grinding equipment for optical instruments usually refers to the upper swing type grinding and polishing machine and the lower swing type grinding and polishing machine. The grinding and polishing machine includes a mounting fixture for mounting the grinding ball and a pressure mechanism. The lens to be polished is placed on the grinding ball of the mounting fixture and pressed by the pressure structure. First, the grinding is performed by the rotation of the mounting fixture. Secondly, the grinding angle of the grinding ball is also controlled by the swing of the upper or lower swing arm.

[0003] However, when polishing, the existing polishing machine may cause the pressure shaft to vibrate during the polishing process due to the misalignment of the installation position of the grinding ball, the downward pressure position of the pressure shaft in the pressure mechanism, and the swing center position of the upper and lower swing mechanisms. The vibration of the pressure shaft is an external manifestation, but the impact of the poor stability of its installation position is that the quality of the polished lens will inevitably be affected.

[0004] In the prior art, when the pressure shaft vibrates, it is impossible to analyze the cause of the vibration, and thus it is impossible to accurately adjust the misaligned installation position of the polishing machine, resulting in low work efficiency and poor lens polishing quality. Summary of the invention

[0005] In response to the technical problem raised in the background technology that the cause of the vibration of the pressure shaft cannot be analyzed, the present invention uses a dimensional meter to display the vibration form, and performs vibration analysis based on the specific vibration form caused by the polishing machine part, so as to determine the installation misalignment position and achieve accurate adjustment.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A detection method for a fine grinding and polishing machine comprises the following steps:

[0008] S1. Install a dimensional gauge on the pressure shaft mechanism of the polishing machine, and use the dimensional gauge to measure the jitter form of the pressure shaft, that is, the jitter form of the pressure shaft is more intuitively displayed through the pointer of the dimensional gauge;

[0009] S2. The vibration amplitude and frequency of the pressure axis vary according to the different dislocation installation forms of the polishing machine, so the swing amplitude and frequency of the inch gauge pointer are also different;

[0010] S3. According to the swing amplitude and frequency of the pointer of the dimensional gauge, the possible cause of the jitter state and the misaligned installation cause and the misaligned installation position are inferred, and the installation accuracy is accurately adjusted for the misaligned installation position to reduce the jitter of the pressure shaft;

[0011] S4, judging whether the misaligned installation position of the polishing machine is correct by the reduction degree of the vibration of the pressure shaft;

[0012] S5. Compare the data between the vibration of the pressure shaft and the offset installation position of the polishing machine, and finally form an accurate offset installation and debugging process.

[0013] Through the above technical scheme, the present invention uses a dimensional meter to display the jitter form, and performs jitter analysis based on the specific jitter form caused by the polishing machine part, so as to achieve the purpose of determining the installation misalignment position and achieving accurate adjustment.

[0014] The present invention is further configured as follows: the staggered installation form in step S2 is as follows:

[0015] The first type of misaligned installation is that the grinding balls are installed on different axes on the mold;

[0016] Since the rotation frequency of the mold is 3000r / min, the swing form of the sizing gauge pointer is: high-frequency small-amplitude swing;

[0017] The second type of misaligned installation is: the ball center height of the swing axis is high, that is, it deviates from the standard ball center height;

[0018] Since the swing frequency of the swing shaft is 50 swings / min, the swing form of the fixed-size indicator pointer is: low-frequency small-amplitude swing;

[0019] The third type of misaligned installation is: the pressure head and the pressure axis are not coaxial, that is, the pressure head is installed skewed;

[0020] Due to the deviation of the pressing position of the pressure head, the swing form of the dimensional gauge pointer is: jumping swing.

[0021] The present invention is further configured as follows: in step S5, data comparison is formed between the vibration of the pressure shaft and the misaligned installation position of the adjustment polishing machine, and finally intelligent debugging software can be formed.

[0022] Based on claims 1-4 above, a fine grinding and polishing machine using a precise correction process method is proposed, comprising a frame, a pressure shaft, a pressure head, grinding balls, a rotating shaft and a mounting mold, wherein the pressure shaft is vertically slidably mounted on the frame, the pressure head is detachably mounted on the bottom end of the pressure shaft, and a dimensional gauge for testing the shaking state of the pressure shaft is mounted on the frame.

[0023] The present invention is further configured such that: the dimension gauge is a dial gauge or a micrometer.

[0024] In summary, the present invention has the following beneficial effects:

[0025] (1) The misaligned position of the polishing machine can be accurately found;

[0026] (2) Be able to intuitively perceive whether the polishing machine is working normally;

[0027] (3) The precision of lens processing and polishing is greatly improved;

[0036] S2. The vibration amplitude and frequency of the pressure axis vary according to the different dislocation installation forms of the polishing machine, so the swing amplitude and frequency of the inch gauge pointer are also different;

[0043] The second type of misaligned installation is: the spherical center height of the rotating axis is higher, that is, it deviates from the standard spherical center height;

[0044] Since the swing frequency of the rotating shaft is 50 swings / min, the swing form of the fixed-size indicator pointer is: low-frequency small-amplitude swing;

[0045] The third type of misaligned installation is: the pressure head and the pressure axis are not aligned, that is, the pressure head is installed skewed;

[0046] Due to the deviation of the pressing position of the pressure head, the swing form of the dimensional gauge pointer is: jumping swing.

[0047] In step S5, data comparison is formed between the vibration of the pressure shaft and the misaligned installation position of the polishing machine, and finally intelligent debugging software can be formed.
