Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically a wedge feeler gauge calibration device. Background Technology

[0002] Wedge gauges, typically made of metal with graduations on their beveled side, are field measuring tools used in construction. They are also known as gap gauges or thickness gauges. The main purpose of wedge gauges is to measure the gaps between two surfaces, such as those on machine tools, piston ring grooves and rings, cylinders and pistons, crosshead slides and guide plates, the tops of intake and exhaust valves and rocker arms, and gear meshing clearances.

[0003] Current wedge gauges require manual calibration, which is wasteful of manpower and resources and inefficient. It also places high demands on the operators, and improper operation by the operator directly affects the accuracy of the measurement results. Summary of the Invention

[0004] The purpose of this invention is to provide a wedge gauge calibration device to solve the problems mentioned in the background art.

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

[0006] A wedge feeler gauge calibration device includes a calibration table. Support plates are symmetrically arranged on the top of the calibration table. A first slide rail is provided on the top of the calibration table, located between the support plates. A left moving block and a right moving block are slidably arranged on the first slide rail from left to right. A fixing bolt is threaded to the bottom front side of the left moving block. A CCD camera is provided on the top of the left moving block. A mounting hole is provided inside the left moving block near the right moving block. A distance sensor is installed inside the mounting hole and connected to an external display device. The side of the distance sensor is flush with the side of the left moving block. A second electric push rod is connected to the right side of the right moving block, and the bottom end of the second electric push rod is fixed to the support plate on the right side.

[0007] As a further aspect of the present invention: the distance between the mounting hole and the top of the left moving block is greater than the height of the inclined surface of the wedge gauge.

[0008] As a further embodiment of the present invention: a horizontal plate is provided on the top of the support plate, a slider is slidably provided below the horizontal plate, a first electric push rod is connected to the bottom of the slider, a clamping device housing is connected to the bottom of the first electric push rod, a lead screw is provided through the middle of the clamping device housing and extending to both ends, the part of the lead screw inside the clamping device housing is provided with opposite threaded areas, both ends of the lead screw extend out of the clamping device housing, a rotating handle is fixedly connected to both ends of the lead screw, sliding grooves are opened on both sides of the bottom end of the clamping device housing, sleeves are symmetrically arranged in the sliding grooves, threaded holes are provided in the sleeves, the lead screw is helically connected to the sleeves, a clamping plate is provided at the bottom of the clamping device housing, and the bottom of the sleeve is fixedly connected to the top of the clamping plate.

[0009] As a further embodiment of the present invention, a limit block is provided in the middle of the slide.

[0010] As a further embodiment of the present invention: a second slide rail is provided at the bottom of the horizontal plate, and the slider is slidably installed below the second slide rail.

[0011] As a further embodiment of the present invention: the support plate is provided with corresponding bearing seats, and the bearing seats are connected by threaded columns, which pass through the slider and are threadedly connected to the slider; a reduction motor is fixedly mounted on the support plate on the right side by a bracket, and the motor shaft of the reduction motor is fixedly connected to the right end of the threaded column.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. By setting the first slide rail, the left moving block and the right moving block, a detection gap can be formed between the right moving block and the left moving block. At the same time, by setting the distance sensor, the distance between the right moving block and the left moving block can be measured in real time, which is convenient for accurately setting the gap.

[0014] 2. By using the CCD camera located at the top of the left moving block, the measurement point of the scale above the moving block of the wedge feeler gauge can be automatically found when the wedge feeler gauge is placed in the detection gap, replacing the human eye alignment and avoiding errors caused by human eye reading.

[0015] 3. The wedge gauge is calibrated based on the data measured by the CCD camera and distance sensor. The data is automatically measured. The wedge gauge is held vertically after clamping, and its left and right movement and lifting are controllable, making the calibration convenient and highly accurate.

[0016] 4. By rotating the handle, the lead screw is driven to rotate, which in turn causes the sleeve to slide inside the groove, thereby causing the clamping plates to move in opposite directions, clamping and fixing the wedge gauge, which is easy to adjust and has a good fixing effect.

[0022] Example 1

[0023] Please see Figure 1In this embodiment of the invention, a wedge feeler gauge calibration device includes a calibration table 1. Support plates 2 are symmetrically arranged on the top of the calibration table 1. A first slide rail 3 is arranged on the top of the calibration table 1, located between the support plates 2. A left moving block 15 and a right moving block 12 are slidably arranged on the first slide rail 3 from left to right. A fixing bolt 13 is threadedly connected to the bottom front side of the left moving block 15. A CCD camera 14 is arranged on the top of the left moving block 15. A mounting hole 16 is provided inside the left moving block 15 near the right moving block 12. The distance between the mounting hole 16 and the top of the left moving block 15 is greater than the height of the inclined surface of the wedge feeler gauge. A distance sensor 17 is arranged inside the mounting hole 16. The distance sensor 17 is connected to an external display device. The distance sensor 17 is flush with the side of the left moving block 15. The right moving block 12 is connected to the right side of the second electric push rod 18, and the bottom end of the second electric push rod 18 is fixed on the right side support plate 2. Through the set 27, the first slide rail 3, the left moving block 15 and the right moving block 12, a detection gap can be formed between the right moving block 12 and the left moving block 15. At the same time, the distance sensor 17 can measure the distance between the right moving block 12 and the left moving block 15 in real time. Through the CCD camera 14 set on the top of the left moving block 15, the measurement point position of the scale of the wedge gauge above the moving block can be automatically found, replacing the human eye alignment and avoiding the error caused by human eye reading.

[0024] Example 2

[0025] Please see Figure 2-3Based on embodiment 1, a horizontal plate 4 is provided at the top of the support plate 2, a second slide rail 5 is provided at the bottom of the horizontal plate 4, and a slider 7 is slidably provided below the second slide rail 5. Corresponding bearing seats 10 are provided inside the support plate 2, and threaded posts 6 are connected between the bearing seats 10. The threaded posts 6 pass through the slider 7 and are threadedly connected to the slider 7. A reduction motor 11 is fixedly provided on the right support plate 2 via a bracket, and the motor shaft of the reduction motor 11 is fixedly connected to the right end of the threaded post 6. A first electric push rod 8 is connected to the bottom of the slider 7, and a clamping device housing 9 is connected to the bottom of the first electric push rod 8. A lead screw 23 is provided through the middle of the clamping device housing 9 at both ends. The portion of the lead screw 23 located inside the clamping device housing 9 is provided with… Conversely, in the threaded area 22, both ends of the lead screw 23 extend into the clamping device housing 9. A rotating handle 19 is fixedly connected to both ends of the lead screw 23. Slide grooves 26 are provided on both sides of the bottom of the clamping device housing 9. Sleeves 21 are symmetrically arranged within the slide grooves 26, each with a threaded hole 20. The lead screw 23 is helically connected to the sleeve 21. A clamping plate 24 is provided at the bottom of the clamping device housing 9, with the bottom of the sleeve 21 fixedly connected to the top of the clamping plate 24. A limit block 25 is provided in the middle of the slide groove 26. By rotating the rotating handle 19, the lead screw 23 rotates, causing the sleeve 21 to slide within the slide groove 26, which in turn causes the clamping plate 24 to move in opposite directions, clamping and fixing the wedge gauge. This facilitates adjustment and provides a good fixing effect.

[0026] After the wedge feeler gauge is clamped and fixed, the slider 7 is moved to a suitable position, and the first electric push rod 8 is extended so that the inclined surface of the wedge feeler gauge abuts against the left moving block 15. The CCD camera 14 automatically finds the measurement point position of the scale of the wedge feeler gauge above the moving block. During this process, the left moving block 15 is automatically moved to the left under force. After the measurement point position is determined, the left moving block 15 is fixed by tightening the fixing bolt 13. The second electric push rod 18 is extended until the right moving block 12 abuts against the straight surface of the wedge feeler gauge and then stops. The distance sensor 17 can then measure the distance between the left moving block 15 and the right moving block 12. The wedge feeler gauge is then calibrated based on the data. The data is automatically measured. After the wedge feeler gauge is clamped, it remains in a vertical state. Its left and right movement and lifting are controllable, making the calibration convenient and highly accurate.
