Description

Technical Field

[0001] This utility model relates to measuring devices, and in particular to a high-precision measuring device for CNC machine tools. Background Technology

[0002] The high-precision measuring device for CNC machine tools is used to monitor and calibrate the machining accuracy of the machine tool in real time, ensuring that the size and shape of the parts meet the design requirements. The device collects data through high-precision sensors and feeds it back to the CNC system for automatic adjustment and correction, improving machining quality and efficiency. At the same time, it can perform online detection, promptly detect and correct machining errors, reduce material waste, extend tool life, and ensure the stability and reliability of the production process.

[0003] In practical work, existing high-precision measuring devices can be used together to basically meet the measurement needs of materials. However, when dealing with materials with large size differences, their fixing ability is insufficient and they cannot firmly fix the materials. This may cause the materials to shift or shake during the measurement process, which seriously affects the accuracy of the measurement and makes it impossible to obtain accurate measurement data. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, this utility model proposes a high-precision measuring device for CNC machine tools, which realizes the accurate measurement of material data of different sizes through the cooperation between the clamping component and the first measuring component and the second measuring component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-precision measuring device for CNC machine tools includes a horizontally arranged support base plate, a second support plate vertically arranged on the upper surface of the support base plate, a clamping assembly arranged on the second support plate along the vertical direction, a second measuring assembly for measuring vertical dimensions arranged on one side of the clamping assembly on the second support plate, and a first measuring assembly for measuring horizontal dimensions arranged on the support base plate perpendicular to the second measuring assembly.

[0007] The clamping assembly includes a support slide plate fixed vertically to a second support plate. A first motor is provided at the upper end of the support slide plate. A groove is vertically formed in the middle of the support slide plate. A fixed block, a sliding clamping block, and a first lead screw are respectively provided at the upper and lower ends of the groove. One end of the first lead screw passes through the fixed block and the support slide plate in sequence and is connected to the power output shaft of the first motor. The other end is threadedly connected to the sliding clamping block. The first motor drives the first lead screw to rotate in the groove, thereby driving the sliding clamping block to move in the groove. Damping springs are respectively provided on opposite sides of the fixed block and the sliding clamping block. A second clamping plate is provided at the other end of the damping spring.

[0008] The second measuring component includes a first fixing plate and a second fixing plate fixedly mounted on a second support plate. A second motor is mounted on the upper end of the first fixing plate. The power output shaft of the second motor is connected to a second lead screw. The second lead screw passes through the first fixing plate and the second fixing plate and is movably connected. A transmission plate is threaded onto the second lead screw between the first fixing plate and the second fixing plate. A second measuring plate is mounted on the transmission plate near the clamping component. A vertical measuring ruler is mounted between the first fixing plate and the second fixing plate, parallel to the second lead screw.

[0009] The first measuring component includes a lifting rod fixedly mounted on the upper surface of a support base plate. A first support plate is connected above the lifting rod. A sliding groove and a horizontal measuring ruler are arranged parallel above the first support plate. A sliding block is slidably mounted in the sliding groove. A support block is mounted on the sliding block. A first measuring plate is mounted on the side of the support block near the clamping component.

[0010] The support base plate is provided with fixing components on both sides of the second support plate. The fixing components include a positioning plate located on the lower surface of the support base plate, which is fixedly connected to the top of the positioning plate through the first support column passing through the support base plate. The top of the two adjacent first support columns on the same side of the second support plate is provided with a first clamping plate, and a positioning bolt is provided through the first clamping plate.

[0011] The first measuring plate is set in the vertical direction of the horizontal measuring ruler.

[0012] A second support column is provided on the first support plate, and the horizontal measuring ruler is fixed on the second support column.

[0013] The second support plate has a clamping assembly on one side and a support frame fixedly connected to the other side to improve the stability of the second support plate.

[0014] The outer perimeter of the supporting base plate and the upper half of the second supporting plate are chamfered.

[0015] This utility model has the following beneficial effects:

[0016] This invention uses a first motor to drive a first lead screw to rotate. When the first lead screw rotates, it causes a sliding clamping block to move on a supporting slide plate, allowing it to cooperate with a fixed block to clamp the object. The supporting slide plate provides stable support for the entire clamping device. The combination of a damping spring and a second clamping plate acts as a buffer during clamping, effectively preventing damage to the material due to excessive clamping force and ensuring that the clamping operation is both firm and safe. The second motor drives a second lead screw to rotate, and the transmission plate on the second lead screw can be raised and lowered under its influence, thereby enabling the vertical measuring ruler to measure the object. The first measuring plate can directly contact the material for measurement, while the horizontal measuring ruler can accurately measure data, providing accurate quantitative basis for the measurement results. At the same time, the lifting rod can flexibly adjust the height of the entire assembly to meet the needs of different measuring parts. Attached Figure Description

The first measuring plate 35 can directly contact the material for measurement, and the horizontal measuring ruler 37 at the top of the second support column 36 can accurately measure the data and provide accurate quantitative basis for the measurement results.

[0032] like Figure 3As shown, fixing components 2 are provided on both sides of the second support plate 4 on the supporting base plate 1. The fixing components 2 include a positioning plate 21 located on the lower surface of the supporting base plate 1.

When the first lead screw 56 rotates, it drives the sliding clamping block 54 to move on the support slide plate 51, so that it cooperates with the fixing block 53 to achieve the clamping operation of the item. The support slide plate 51 provides stable support for the entire clamping device. The combination of the damping spring 55 and the second clamping plate 57 plays a buffering role during the clamping process, which can effectively prevent damage to the material due to excessive clamping force and ensure that the clamping operation is both firm and safe.
