Gear modulus as an important parameter to measure the size of the gear specification, its accuracy is crucial to ensure the good meshing between gears.

[0003] At present, gears are mostly detected by detection machines after production. First, the root circle diameter of an authenticated standard gear part is accurately measured, and the micrometer is adjusted to zero state. Then, other gear parts of the same model to be detected are installed one by one on the detection machine and aligned with the standard measurement position. The root circle diameter of the gear to be measured is measured again using the micrometer. If the micrometer shows deflection, it means that the root circle diameter of the gear to be measured is different from the standard gear, thus indirectly reflecting the deviation of the gear modulus. However, in the above detection method, the gear alignment is generally manually operated. Due to human factors, it is often difficult for the staff to accurately grasp the size of the force applied. Excessive force may cause scratches on the surface of the gear, or even damage. CONTENT OF THE UTILITY MODEL

[0028] In one embodiment of the utility model, as shown in Figures 1-6 A gear simulation detection machine is provided, which comprises a base 10, a detection table 20 and a detection mechanism. The base 10 is provided with a workbench 11, and the workbench 11 is provided with a guide rail. The detection table 20 is movably connected to the center of the workbench 11 and is used for placing the gear. Two groups of limiting components 21 for limiting the gear are arranged on one end of the detection table 20. The detection mechanism comprises a fixed seat 30 and a sliding detection seat 40. The fixed seat 30 is movably arranged on the workbench 11 and located on the side of the detection table 20 close to the limiting component 21. The fixed seat 30 is provided with a pressure sensor 31. The sliding detection seat 40 is movably arranged on the workbench 11 and located on the other side of the detection table 20. The side of the sliding detection seat 40 away from the detection table 20 is connected with a moving driving part 41. The moving driving part 41 is electrically connected with the pressure sensor 31.

[0029] In the embodiment, the base 10 bottom end is also provided with four groups of circumferentially distributed buffer seats, when the object supported by the base 10 is impacted by external force, the buffer seats can effectively absorb and disperse the impact force, thereby reducing the interference of the gear detection.

[0030] By setting the pressure sensor 31 and the moving driving part 41, the worker places the gear on the detection table 20, and under the action of the limiting parts 21 on both sides, the gear can be quickly positioned on the detection table 20, the moving driving part 41 drives the sliding detection seat 40 to move towards the fixed seat 30, and then the fixed seat 30 and the sliding detection seat 40 abut against both ends of the gear, and whether the modulus of the gear deviates from the modulus of the standard gear is judged according to the micrometer 44 on the sliding detection seat 40, the moving driving part 41 controls the movement of the sliding detection seat 40 to replace manual movement, so that the force of the sliding detection seat 40 always remains consistent, avoiding the phenomenon that the gear is damaged due to the inability to control the force when manually moving, and at the same time, the pressure sensor 31 is arranged in the fixed seat 30, the pressure sensor 31 monitors the force applied to the gear in the alignment process in real time, when it is detected that the applied force exceeds the preset safety range, the moving driving part 41 will slow down or stop moving, effectively avoiding scratching or damaging the gear surface by excessive force.

[0031] Further, the fixed seat 30 is provided with a first detection head 32. The pressure sensor 31 is located at the end of the fixed detection head. The first locking screw 33 is arranged between the fixed seat 30 and the fixed detection head. By setting the first locking screw 33, the worker can replace the first detection head 32 by loosening or tightening the first locking screw 33, so as to adapt to the detection of gears with different modulus.

[0032] Further, the fixed seat 30 is also provided with a digital display instrument 34, and the digital display instrument 34 is electrically connected with the pressure sensor 31. By setting the digital display instrument 34, it can display the reading of the pressure sensor 31 in real time, so that the worker can intuitively understand the size of the current applied force, and make a judgment according to the size of the force, thereby avoiding the problem of scratching or damaging the gear due to excessive force.

[0033] Further, the fixed seat 30 is provided with an outwardly extending boss 35 away from the detection table 20. The boss 35 is provided with a second locking screw 36 abutting against the detection table 20. By setting the second locking screw 36, when detecting different types of gears, the fixed seat 30 is moved to the specified position, and then the second locking screws 36 on both sides are tightened, so that the second locking screws 36 are locked with the top surface of the detection table 20, realizing the quick fixing of the fixed seat 30, simplifying the positioning steps of the positioning seat, and further improving the adjustment efficiency of the fixed seat 30.

[0034] Further, the sliding detection seat 40 is provided with a second detection head 42. The second detection head 42 is connected with a detection rod 43 at the end, and the detection rod 43 is arranged in the sliding detection seat 40. The detection rod 43 is connected with a micrometer 44 at the end. The second detection head 42 is in contact with the gear, and under the action of the detection rod 43, the force of the contact with the gear is transmitted to the micrometer 44, so that the worker can judge whether the modulus of the detected gear meets the standard according to the value on the micrometer 44.

[0035] Further, the detection rod 43 is provided with a clamping pin 45 between the second detection head 42. The clamping pin 45 is provided with a reset spring 46 between the detection rod 43. The second detection head 42 and the detection rod 43 are provided with a third locking screw 47. In this embodiment, the detection rod 43 includes an outer layer and an inner layer. The clamping pin 45 is clamped in the inner layer, and the end of the clamping pin 45 is in contact with the side surface of the second detection head 42, thereby playing a role in preliminarily fixing the second detection head 42, facilitating the subsequent locking of the second detection head 42. At the same time, the reset spring 46 is located between the clamping pin 45 and the inner layer. When the outer layer and the inner layer are misaligned and separated, the clamping pin 45 moves upward under the action of the reset spring 46, thereby contacting and fixing the second detection head 42, facilitating the replacement of the second detection head 42.

[0036] Further, the moving drive 41 is provided with a connecting rod 48 between the sliding detection seat 40. The moving drive 41 is a gas cylinder. By arranging the connecting rod 48, the micrometer 44 and the moving drive 41 have a certain distance, thereby avoiding the phenomenon of positional interference between the two.

[0037] Further, the limiting part 21 includes a vertical plate 211 and a limiting block 212. The vertical plate 211 is vertically arranged on one side of the detection table 20. The limiting block 212 is movably connected to the vertical plate 211, and a adjusting rail is arranged between the limiting block 212 and the vertical plate 211. The adjusting rail is provided with a clamping piece between the adjusting rail and the vertical plate 211. By arranging the limiting block 212 and the clamping piece, the worker adjusts the position of the limiting block 212 according to the type of the detected gear, and the clamping piece and the vertical plate 211 are clamped with each other, thereby realizing the quick fixing of the limiting block 212, simplifying the adjustment and installation steps of the limiting block 212, and improving the detection efficiency of the gear modulus.

[0038] Further, the clamping piece comprises a moving block 213 and a telescopic rod 214. The moving block 213 is arranged on the side of the vertical plate 211 away from the limiting block 212. The telescopic rod 214 is arranged between the moving block 213 and the limiting block 212, and the two ends of the telescopic rod 214 are connected with the limiting block 212 and the moving block 213 respectively. The moving block 213 is provided with a bolt 215. The bolt 215 is provided with a fastening head 216 at one end. The bolt 215 and the vertical plate 211 are provided with a fixing groove therebetween. The fastening head 216 is tightly connected with the fixing groove. In the embodiment, the fastening head 216 is an elastic rubber head, which can be wedge-shaped or drum-shaped with a small head and a large middle. When the limiting block 212 is adjusted to the required position, the moving block 213 is pressed towards the side of the vertical plate 211, the fastening head 216 at the end of the bolt 215 is inserted into the fixing groove, and the fastening head 216 is tightly connected with the fixing groove, so that the quick fixing of the limiting block 212 is realized, the adjusting and installing steps of the limiting block 212 are simplified, and the detection efficiency of the gear modulus is improved.
