Technical Field
[0001] This utility model relates to the field of flatness measurement technology, and in particular to an in-situ flatness measurement device for a horizontal spindle table surface grinder. Background Technology
[0002] A horizontal-spindle rectangular-table surface grinder is a type of surface grinder with a horizontal grinding head spindle and a rectangular worktable. It is mainly used for high-precision grinding of flat surfaces, bevels, grooves, and flanges on workpieces. When using a horizontal-spindle rectangular-table surface grinder for grinding, to ensure machining accuracy, it is necessary to perform in-situ measurement of flatness during the grinding process. This allows for real-time feedback of the workpiece flatness, facilitating timely adjustments.
[0003] Flatness in-situ measurement devices typically employ non-contact measurement technologies such as laser displacement sensors or capacitive displacement sensors. These sensors perform real-time detection of the workpiece's machined surface, thus achieving in-situ measurement. However, some existing measuring devices mount the sensor on the grinding head or workpiece, where vibrations generated during grinding affect measurement accuracy. Others mount the sensor on the machining platform using a bracket, reducing the impact of grinding vibrations. However, this fixed setup prevents adjustment of the device's position on the machining platform, resulting in poor flexibility and adaptability. Utility Model Content
[0004] The main objective of this invention is to provide a flatness measurement device for a horizontal spindle table surface grinder, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] Preferably, a column is installed on the grinding machine base, and a drive box is provided on the column. The drive box contains a drive motor, and a grinding wheel connected to the drive motor is provided at the end of the drive box.
[0008] Preferably, the sliding seat is provided with a screw hole, and the sliding seat is threadedly connected to the lead screw through the screw hole, and the sliding seat is slidably installed on the inner side of the cross frame.
[0009] Preferably, the bottom sliding structure includes a slider, a support plate, a groove, and a clamping component. The slider is fixedly connected to the support plate and is slidably mounted on the processing platform. The groove is formed on the slider, and the clamping component is installed in the groove on the slider.
[0010] Preferably, the clamping assembly includes a connecting post, a lifting block, a round block, a clamping spring, a ball bearing, and a connecting cover. The connecting post is fixed in a groove, the lifting block is fixedly connected to the round block, and the lifting block and the round block are located in the groove. The upper end of the clamping spring is sleeved on the connecting post, and the lower end of the clamping spring is connected to the round block. The connecting cover is connected to the lifting block, and the lifting block and the connecting cover have spherical grooves inside.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] like Figures 1-4 As shown, a flatness measuring device for a horizontal spindle surface grinder includes a grinder base 1, a processing platform 2 on the grinder base 1 with a sliding groove, a fixed column 3 on the processing platform 2, and a bottom sliding structure 4 connected to the processing platform 2 at the lower end of the fixed column 3. A crossbeam 5 is provided at the upper end of the fixed column 3, and an end cap 6 is fixed to the end of the crossbeam 5. A servo motor 7 is mounted on the fixed column 3. A lead screw 8 and a sliding seat 9 are provided inside the crossbeam 5, and a laser sensor 10 is fixed on the sliding seat 9. A column 11 is mounted on the grinder base 1, and a drive box 12 is provided on the column 11. A drive motor is located inside the drive box 12, and a grinding wheel 13 connected to the drive motor is located at the end of the drive box 12. The sliding seat 9 has a screw hole and is threadedly connected to the lead screw 8 through the screw hole. The sliding seat 9 is slidably mounted inside the crossbeam 5.
[0019] When machining a workpiece using a horizontal spindle rectangular table surface grinder, the measuring device is mounted on the machining platform 2 via a bottom sliding structure 4 located in a groove. The workpiece to be machined is mounted on the machining platform 2 near the grinding wheel 13. The controller on the grinder base 1 activates the internal mechanisms of the column 11 and drive box 12, causing the drive motor to rotate and grind the grinding wheel 13, thus grinding the workpiece surface. During grinding, the laser sensor 10 on the sliding seat 9 is activated to detect the workpiece surface. During this process, the servo motor 7 at the upper end of the fixed column 3 operates, rotating the lead screw 8 between the fixed column 3 and the end cover 6. Driven by the lead screw 8, the sliding seat 9 moves inside the crossbeam 5, thereby moving the laser sensor 10 and achieving the purpose of measuring the flatness of the workpiece surface. The measurement result is fed back to the industrial computer via a cable, and the industrial computer issues instructions for real-time adjustments to ensure the grinding accuracy of the horizontal spindle rectangular table surface grinder.
[0020] According to the above implementation scheme, the bottom sliding structure 4 includes a slider 401, a support plate 402, a groove 403 and a clamping component 404. The slider 401 is fixedly connected to the support plate 402 and the slider 401 is slidably mounted on the processing platform 2. The groove 403 is opened on the slider 401 and the clamping component 404 is installed in the groove 403 on the slider 401. The clamping assembly 404 includes a connecting post 4041, a lifting block 4042, a round block 4043, a clamping spring 4044, a ball bearing 4045, and a connecting cover 4046. The connecting post 4041 is fixed in the groove 403. The lifting block 4042 is fixedly connected to the round block 4043, and the lifting block 4042 and the round block 4043 are located in the groove 403. The upper end of the clamping spring 4044 is sleeved on the connecting post 4041, and the lower end of the clamping spring 4044 is connected to the round block 4043. The connecting cover 4046 is connected to the lifting block 4042, and the lifting block 4042 and the connecting cover 4046 have spherical grooves inside. The ball bearing 4045 is disposed in the spherical grooves, and a portion of the ball bearing 4045 passes through the connecting cover 4046.
[0021] When installing the bottom sliding structure 4, the slider 401 is set into the groove on the processing platform 2, and the support plate 402, as the support base of the fixed column 3, is located on the upper surface of the processing platform 2. At this time, the clamping spring 4044 in the clamping component 404 in the groove 403 is in a compressed state. The clamping spring 4044 connected to the connecting column 4041 applies an elastic force to the lifting block 4042 at the lower end of the round block 4043. The lifting block 4042 causes the lower end of the ball 4045 to contact the bottom surface of the groove, thereby applying a clamping force to ensure that the slider 401 is stably set in the groove on the processing platform 2, thus ensuring the stability of the measuring device during use. When the measuring device needs to be moved, the fixed column 3 applies force to the bottom sliding structure 4. Although the clamping spring 4044 causes the ball 4045 to abut against the bottom surface of the slide groove, due to the rolling characteristics of the ball 4045, under the push of the external force, the ball 4045 can rotate in the spherical groove on the lifting block 4042 and the connecting cover 4046, thereby moving along the slide groove, so that the bottom sliding structure 4 can move and adjust normally. After adjustment, the clamping component 404 is used to clamp and fix it.
[0022] It should be noted that the entire device is mounted on the processing platform 2 by means of the fixed column 3, bottom sliding structure 4, crossbar 5, end cover 6, servo motor 7, lead screw 8, sliding seat 9, and laser sensor 10. While ensuring measurement accuracy, the sliding seat 9 and laser sensor 10 can move horizontally, improving detection flexibility. The bottom sliding structure 4 is equipped with a slider 401, support plate 402, and clamping component 404. Due to its elasticity, the clamping component 404 can provide clamping, ensuring effective support and stable operation of the device. At the same time, the clamping component 404 is equipped with clamping spring 4044, ball bearing 4045, etc., which does not affect the normal movement of slider 401 on the processing platform 2, making it easy to adjust the position of the entire measuring device and providing high adaptability.
[0023] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
