[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application (for the convenience of description and understanding, the following is Figure 2All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] See also Figure 1-2 The present application provides a technical solution: a device for detecting the roundness and straightness of an electric spindle, comprising a support base 9, clamping devices for placing shaft members are arranged on both sides of the support base 9, a linear slide rail 12 is arranged on the upper surface of the straight section of the support base 9, and a sliding mounting plate 6 is slidably arranged on the linear slide rail 12.

[0017] The support base 9 has a stable structure to ensure stability during the detection process. The clamping device is used to firmly fix and position the shaft to be detected to ensure that the shaft will not move or deform unnecessarily during precision measurement, thereby affecting the accuracy of the measurement result.

[0018] The linear guide rail 12 provides a stable linear motion track for the sliding mounting plate 6 , so that the micrometer 11 mounted thereon can be accurately and smoothly adjusted in the horizontal direction.

[0019] A support guide frame 4 is arranged on the upper surface of the sliding mounting plate 6. The support guide frame 4 is of arched design, and a sliding connecting seat 13 is slidingly arranged in the sliding groove on the arch. A column vertical support 3 is arranged on the upper surface of the sliding connecting seat 13. A rotating guide sleeve 14 is sleeved on the outer side surface of the column vertical support 3. A connecting plate is arranged on one side of the rotating guide sleeve 14, and a micrometer 11 is connected to the connecting plate.

[0020] The slide groove on the arched structure of the support guide frame 4 enables the sliding connection seat 13 to slide smoothly therein, giving it adjustability in the front and rear directions. The relative position between the micrometer 11 and the spindle 2 to be tested can be adjusted according to actual needs to adapt to the detection requirements of spindles of different diameters or lengths.

[0021] The column support 3 is the mounting carrier of the rotating guide sleeve 14 and allows the micrometer 11 to be accurately adjusted in a certain angle range, ensuring that the measuring head of the micrometer 11 can accurately fit the outer side of the spindle 2 to be tested, thereby realizing precise detection of the spindle rotation angle change.

[0022] The micrometer 11 is tangent to the outer side surface of the main shaft 2 to be tested which is arranged on the clamping device. A connecting support plate 7 is arranged on one side of the lower surface of the sliding mounting plate 6. The connecting support plate 7 is connected to a screw driving device.

[0023] The micrometer 11 is tangent to the outer side of the spindle 2 to be tested, which is set on the clamping device. When the spindle 2 to be tested rotates, the measuring end of the micrometer 11 will slide along the outer circumferential surface of the spindle, so that the angle change of each degree or even smaller units of the spindle can be accurately captured. The high accuracy and sensitivity of the detection are ensured, and the manufacturing error and dynamic performance of the spindle can be accurately evaluated.

[0024] The screw drive device can realize precise control and adjustment of the position of the spindle 2 to be detected. In actual operation, by manipulating the screw drive device, the sliding mounting plate 6 can be driven to move smoothly along the linear guide rail 12, thereby changing the contact position between the micrometer 11 and the spindle, realizing detection of different positions of the spindle, and further improving the functionality and flexibility of the equipment.

[0025] Furthermore, the clamping device includes a clamping seat 1 and a shaft placement plate 5 , a rotating sleeve is provided in the clamping seat 1 , the rotating sleeve is sleeved with the main shaft 2 to be detected, and the other end of the main shaft 2 to be detected is sleeved with the shaft placement plate 5 .

[0026] A rotating sleeve is arranged inside the clamp seat 1. The rotating sleeve can flexibly adapt to spindles of different diameters or specifications, and firmly clamp them by fastening, ensuring that the spindle will not shake or deviate from the predetermined position during the detection process.

[0027] The rotating sleeve accurately positions and clamps the main shaft 2 to be detected, and at the same time allows the main shaft 2 to be detected to rotate smoothly and without damping when being driven, so as to measure the angle change.

[0028] The shaft placement plate 5 provides a stable support point for the main shaft 2 to be detected, and is sleeved with the other end of the main shaft 2 to be detected, forming a constraint state with both ends fixed. The bending deformation of the main shaft 2 to be detected due to uneven force during rotation is effectively avoided, thereby improving the accuracy of detection.

[0029] Furthermore, the shaft placement plate 5 is arranged on the other side of the support base 9, and is connected to the lead screw 8 on the lead screw drive device.

[0030] Furthermore, the clamp seat 1 is arranged on a support located at one end of the support base 9, and a sleeve shaft is arranged on the support, one end of the sleeve shaft is connected to the clamp seat 1, and the other end of the sleeve shaft is connected to a rotating motor.

[0031] In the electric spindle roundness and straightness detection device, the clamp seat 1 is arranged on a specific support at one end of the support base 9. This design ensures that the clamp seat 1 and the spindle 2 to be detected in the internal rotating sleeve have sufficient stability and force support during operation.

[0032] The rotating motor is used as a power source to achieve precise control and continuous rotation of the spindle 2 to be tested. During the testing process, by adjusting the working state of the drive motor, the spindle 2 to be tested rotates within the set angle range or speed. The micrometer 11 can accurately capture the changes in each angular position of the spindle 2 to be tested, thereby completing high-precision measurement of the spindle accuracy.

[0033] Furthermore, the screw drive device includes a screw mounting seat 10, a screw 8 and a drive motor 15. The screw mounting seat 10 is provided on one side of the support base 9. The screw 8 is sleeved between the screw mounting seat 10 and the shaft placement plate 5 located in the clamping device. One end of the screw 8 is connected to the output end of the drive motor 15, and the screw rotating sleeve on the screw 8 is connected to the connecting support plate 7.

[0034] Furthermore, a guide groove is provided on the shaft placement plate 5 , and a bar material holder 16 is provided on the guide groove.

[0035] A guide groove is provided on the shaft placement plate 5 to enhance the stability of the main shaft 2 to be tested thereon and the flexibility of position adjustment. The guide groove can cooperate with the bar clamping frame 16 to facilitate clamping of the main shaft 2 to be tested with different diameters, thereby improving the applicable scope of the test.

[0036] When in use: install the spindle 2 to be tested into the clamping device. Sleeve one end of the spindle 2 to be tested on the rotating sleeve in the clamp seat 1, and ensure that it is firmly fixed and does not shake by tightening; the other end of the spindle 2 to be tested is clamped with the bar clamp 16 on the shaft placement plate 5, forming a fixed constraint state at both ends, and the accuracy and stability of the spindle position can be maintained during the high-precision rotation detection process.

[0037] When performing a straightness test, the drive motor 15 is controlled to rotate the lead screw 8, thereby driving the sliding mounting plate 6 to move smoothly on the linear guide rail 12, and the position of the micrometer 11 is adjusted so that it contacts the outer side of the spindle 2 to be tested. By analyzing the data, the straightness test of the spindle 2 to be tested is obtained.

[0038] When testing the roundness, the rotating motor is used as a power source and is connected to the clamping seat 1 through a sleeve shaft. After starting, the spindle 2 to be tested can be accurately controlled to rotate continuously or within a set range, and the position of the micrometer 11 can be adjusted to make it contact with the spindle 2 to be tested, ensuring that the measuring head is always accurately fitted on the outer side of the spindle 2 to be tested, and capturing and recording every tiny angle change of the spindle 2 to be tested in real time to analyze the roundness.
