Description

Technical Field

[0001] This application relates to the technical field of gear shaft detection technology, and in particular to a detection device for detecting the axial position of a gear shaft. Background Technology

[0002] In the field of mechanical manufacturing, small gears and shafts are often manufactured using a one-piece molding process. After machining, the actual axial position of the gear on the shaft needs to be checked to verify whether the gear is consistent with the preset position. This check is crucial because even a slight axial deviation in the gear's position can directly affect the meshing accuracy with other gears, leading to reduced transmission system efficiency, abnormal noise, or equipment failure.

[0003] Currently, mainstream testing tools consist of a fixed support and a digital dial indicator mounted on the support. During testing, the workpiece (gear shaft) needs to be stably supported, and the end face of the gear shaft away from the gear must be kept horizontal so that the testing probe of the digital dial indicator can press vertically against the surface for measurement. However, when the workpiece is a structure where the gear shaft completely penetrates the gear (i.e., both ends of the shaft significantly protrude from the gear), because the gear shaft is a slender cylinder, if it is placed horizontally on the platform, the shaft will tip over due to the lack of lateral support, making measurement impossible.

[0004] To overcome this deficiency, a special support block with a center hole is used during operation: the end of the gear shaft that penetrates the gear is inserted into the hole of the support block, making the shaft vertical with the end face of the shaft to be tested facing upwards. However, adding a support block has the following drawbacks: the difference in shaft diameter between different gear shafts requires a library of support blocks with multiple hole diameters. Frequent replacement of matching support blocks is necessary during testing, significantly increasing preparation time and thus affecting testing efficiency. Utility Model Content

[0005] To address the problem of low efficiency caused by frequent shim replacements when inspecting gear shafts with different diameters, this application provides a detection device for detecting the axial position of gear shafts.

[0006] The detection device for detecting the axial position of a gear shaft provided in this application adopts the following technical solution:

[0007] A detection device for detecting the axial position of a gear shaft includes a support mechanism, a lateral adjustment mechanism, and a digital dial indicator. The support mechanism includes a base plate, a lifting assembly, and a mounting support plate. The lower end of the lifting assembly is connected to the base plate, and the upper end of the lifting assembly is connected to the mounting support plate. The mounting support plate has a row of mounting holes of different diameters for positioning workpieces. A support rod is vertically connected to the base plate, and a support block is connected to the support rod.

The lateral adjustment block is slidably connected to the support block, and the digital dial indicator is mounted on the lateral adjustment block. The lateral adjustment assembly is mounted on the support block and the lateral adjustment block, and is used to adjust the horizontal position of the lateral adjustment block.

[0008] By adopting the above technical solution, workpieces with different shaft diameters can be directly adapted through a row of mounting holes of different diameters on the mounting support plate, eliminating the need for shim replacement; the horizontal adjustment mechanism achieves precise adjustment of the horizontal position of the digital micrometer through the sliding fit between the support block and the horizontal adjustment block and the drive of the horizontal adjustment component.

[0009] Preferably, the lifting assembly includes a lifting support cylinder, a lifting block, and a spring pin. The lifting support cylinder is vertically connected to the top wall of the base plate, the lifting block is slidably fitted inside the lifting support cylinder, and the mounting support plate is connected to the upper end of the lifting block. The spring pin is installed on the side wall of the lifting support cylinder and is used to position the lifting block inside the lifting support cylinder.

[0010] By adopting the above technical solution, the lifting assembly uses spring pins to lock the position of the lifting block inside the lifting support cylinder, thereby achieving rapid adjustment and fixation of the installation support plate height.

[0011] Preferably, an auxiliary support column is vertically connected to the lower bottom wall of the mounting support plate, and an auxiliary support cylinder is fixedly connected to the upper top wall of the base plate, with the auxiliary support column slidably fitted onto the auxiliary support cylinder.

[0012] By adopting the above technical solution, the sliding cooperation between the auxiliary support column and the auxiliary support cylinder enhances the stability of the installation support plate lifting process.

[0013] Preferably, the lateral adjustment assembly includes a drive rod and a lateral adjustment component. The drive rod is connected to a support block and a drive gear is connected to the drive rod. The lateral adjustment component is a lateral adjustment screw, which is rotatably connected to the support block. A driven gear is connected to the end of the lateral adjustment screw near the drive rod, and the drive gear meshes with the driven gear. The end of the lateral adjustment screw away from the drive rod is threadedly connected to the lateral adjustment block.

[0014] By adopting the above technical solution, the drive rod drives the transverse adjusting screw through the meshing of the drive gear and the driven gear, converting the rotational motion into the linear displacement of the transverse adjusting block, thereby realizing the horizontal fine adjustment of the digital dial indicator.

[0015] Preferably, the lateral adjustment block is connected to a first connecting block and a second connecting block, and there is a gap between the first connecting block and the second connecting block; the digital micrometer is connected to a positioning post, which is disposed in the gap between the first connecting block and the second connecting block; the first connecting block is connected to the second connecting block through a positioning element, which is used to position the positioning post between the first connecting block and the second connecting block.

[0016] By adopting the above technical solution, the positioning component clamps the positioning column by tightening the first connecting block and the second connecting block, thereby enabling the rapid assembly and disassembly of the digital dial indicator.

[0017] Preferably, a detection device for detecting the axial position of a gear shaft further includes a height adjustment component, which is vertically connected to a base plate and also connected to a support block. The height adjustment component is used to adjust the height of the support block.

[0018] By adopting the above technical solution, the height adjustment component drives the support block to rise and fall along the support rod, thereby realizing the height adjustment of the digital dial indicator.

[0019] Preferably, a detection device for detecting the axial position of a gear shaft further includes a clamping assembly. The clamping assembly includes a first clamping block, a second clamping block, and a clamping adjustment member. A clamping support plate is connected to the mounting support plate. The first clamping block and the second clamping block are both connected to the clamping support plate. The first clamping block and the second clamping block are respectively located on both sides of a row of mounting holes of different diameters. The clamping adjustment member connects the first clamping block and the second clamping block. The clamping adjustment member clamps the workpiece through the first clamping block and the second clamping block.

[0020] By adopting the above technical solution, the clamping assembly drives the first clamping block and the second clamping block to move towards each other through the clamping adjustment screw, clamping the workpiece shaft from both sides.

[0021] Preferably, the clamping adjustment component is a clamping adjustment screw, which has external threads with opposite directions at both ends, and the first clamping block and the second clamping block are both threadedly connected to the clamping adjustment screw.

[0022] By adopting the above technical solution, the reverse thread design at both ends of the clamping adjustment screw enables the first clamping block and the second clamping block to move synchronously in opposite directions, thereby improving clamping efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] Workpieces of different shaft diameters can be directly positioned via a row of mounting holes on the support plate, eliminating the need for shim replacement. A height adjustment mechanism allows for height adjustment of the digital dial indicator. A lateral adjustment mechanism converts gear meshing into linear screw motion, driving the digital dial indicator for precise horizontal positioning. The clamping assembly uses a bidirectional screw to synchronously drive clamping blocks to fix the workpiece shaft from both sides. This testing device effectively solves the problem of frequent shim replacement during the testing of multi-specification gear shafts, improving testing efficiency. Attached Figure Description

[0032] This application discloses a detection device for detecting the axial position of a gear shaft, referring to...

[0033] Reference Figures 1-3 The support mechanism 1 includes a base plate 11, a lifting assembly 12, a mounting support plate 13, and a support block 15. The lifting assembly 12 is mounted on the base plate 11. The lifting assembly 12 includes a lifting support cylinder 121, a lifting block 122, and a spring pin 123. The lifting support cylinder 121 is vertically fixed to the top wall of the base plate 11. A first positioning hole 1211 is provided at the upper end of the lifting support cylinder 121. The axis of the first positioning hole 1211 is perpendicular to the axis of the lifting support cylinder 121. The lifting block 122 is slidably fitted inside the lifting support cylinder 121. The lifting block 122 is provided with a plurality of second positioning holes 1221 in the vertical direction, and the second positioning holes 1221 are parallel to the axis of the first positioning holes 1211. A spring pin 123 is fixedly connected to the outer wall of the lifting support cylinder 121, and the pin in the spring pin 123 extends from the first positioning hole 1211 into the second positioning hole 1221, thereby positioning the lifting block 122 on the lifting support cylinder 121. The mounting support plate 13 is fixedly connected to the upper end of the lifting block 122.

[0034] Reference Figures 2-3 An auxiliary support column 131 is vertically fixedly connected to the bottom wall of the mounting support plate 13, and an auxiliary support cylinder 111 is fixedly connected to the top wall of the base plate 11. The auxiliary support column 131 is slidably fitted onto the auxiliary support cylinder 111.

[0035] Reference Figure 1 In this embodiment, the height adjusting component 2 is a height adjusting screw, which is vertically rotatably connected to the top wall of the base plate 11 and is also located on one side of the base plate 11. A support rod 112 is vertically fixedly connected to the top wall of the base plate 11. The support rod 112 is close to the height adjusting screw, and its upper end passes through a sliding hole opened in the mounting support plate 13. A support block 15 is installed on the height adjusting screw and the support rod 112. Specifically, the support block 15 has a threaded hole that is threaded to the height adjusting screw, and a sliding hole that is slidably engaged with the support rod 112.

[0036] Reference Figure 1 and Figure 4 The lateral adjustment mechanism 3 includes a lateral adjustment block 31, a lateral adjustment component 32, and a positioning element 33. A slide rod 151 is fixedly connected to the end of the support block 15 away from the height adjustment component 2, and the length direction of the slide rod 151 is perpendicular to the axis of the height adjustment component 2. The lateral adjustment block 31 is slidably connected to the slide rod 151. A digital dial indicator 4 is installed at the end of the lateral adjustment block 31 away from the height adjustment component 2, and the digital dial indicator 4 is also located opposite to the height adjustment component 2. The lateral adjustment component 32 includes a drive rod 321 and a lateral adjustment element 323. In this embodiment, the lateral adjustment element 323 is a lateral adjustment screw. The drive rod 321 is vertically rotatably connected to the support block 15, and a drive gear 3211 is fixedly connected to the drive rod 321. The axis of the lateral adjusting screw is perpendicular to the axis of the drive rod 321 and parallel to the length direction of the slide rod 151. The end of the lateral adjusting screw near the drive rod 321 is rotatably connected to the support block 15, and a driven gear 3231 is fixedly connected to the end of the screw. The driven gear 3231 meshes with the drive gear 3211. In this embodiment, both the driven gear 3231 and the drive gear 3211 are bevel gears. The end of the lateral adjusting screw away from the drive rod 321 is threadedly connected to the lateral adjusting block 31.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The operator can manually adjust the vertical position of the lifting block 122 in the support mechanism 1 within the lifting support cylinder 121. Specifically, when the lifting block 122 moves to the required height, the spring pin 123 is inserted into the first positioning hole 1211 and the corresponding second positioning hole 1221 to achieve quick locking of the lifting block 122. The mounting support plate 13 rises and falls synchronously with the lifting block 122, and its bottom auxiliary support column 131 slides along the auxiliary support cylinder 111 to enhance structural stability. Subsequently, rotating the height adjustment screw drives the support block 15 to move vertically along the support rod 112, thereby driving the slide rod 151 mounted on the support block 15 and the lateral adjustment mechanism 3 to rise and fall as a whole, achieving fine-tuning of the height of the digital micrometer 4. Subsequently, rotating the drive rod 321 causes the drive gear 3211 fixed to the drive rod 321 to rotate, and the drive gear 3211 meshes with the driven gear 3231 and drives the lateral adjustment screw to rotate. The rotational motion of the lateral adjustment screw is converted into the displacement of the lateral adjustment block 31 along the long axis of the slide bar 151, which ultimately adjusts the horizontal position of the digital micrometer 4 installed at the end of the lateral adjustment block 31.

[0038] Reference Figure 4The end of the lateral adjusting block 31 furthest from the support block 15 is fixedly connected to a first connecting block 311 and a second connecting block 312. The length directions of both the first connecting block 311 and the second connecting block 312 are parallel to the axis of the lateral adjusting member 323. A gap exists between the first connecting block 311 and the second connecting block 312, and a clamping groove 313 is formed between them. In this embodiment, the positioning member 33 is a positioning screw, and the axis of the positioning screw is perpendicular to the length direction of the connecting block. One end of the positioning screw is rotatably connected to the first connecting block 311, and the other end of the positioning screw is threadedly connected to the second connecting block 312. The positioning component 33 is used to position the digital micrometer 4 in the clamping groove 313. Specifically, the digital micrometer 4 is fixedly connected to the positioning post 41. The positioning post 41 of the digital micrometer 4 is placed in the clamping groove 313, and then the positioning screw is rotated to pull the second connecting block 312 toward the first connecting block 311, thereby positioning the digital micrometer 4 between the first connecting block 311 and the second connecting block 312.

[0039] Reference Figure 1 and Figure 5 The clamping assembly 5 includes a first clamping block 51, a second clamping block 52, and a clamping adjustment member 53. In this embodiment, the clamping adjustment member 53 is a clamping adjustment screw. A clamping support plate 14 is vertically fixedly connected to the mounting support plate 13. A support groove 141 is provided on the clamping support plate 14. The length direction of the support groove 141 is perpendicular to the length direction of the mounting support plate 13. The first clamping block 51 and the second clamping block 52 are slidably connected in the support groove 141 on the clamping support plate 14. The length direction of the first clamping block 51 is parallel to the length direction of the second clamping block 52, and the length directions of the first clamping block 51 and the second clamping block 52 are also perpendicular to the length direction of the support groove 141. The clamping adjustment screw is rotatably connected to the clamping support plate 14. The clamping adjustment screw is also located in the support groove 141, and the axis of the clamping adjustment screw is parallel to the length direction of the support groove 141. The clamping adjustment screw has external threads with opposite directions at both ends. The first clamping block 51 and the second clamping block 52 both have threaded holes with opposite directions of rotation. The first clamping block 51 and the second clamping block 52 are both threadedly connected to the clamping adjustment screw.

[0040] Reference Figure 5 The first clamping block 51 is slidably connected to the first telescopic block 511 along the length direction, and the long axis of the first telescopic block 511 is parallel to the long axis of the first clamping block 51. The second clamping block 52 is slidably connected to the second telescopic block 521 along the length direction, and the long axis of the second telescopic block 521 is parallel to the long axis of the second clamping block 52.

[0041] Reference Figure 1 and Figure 5 The mounting support plate 13 has a row of mounting holes 132 of different diameters along its long axis. The mounting holes 132 are located away from the height adjustment component 2, and the axis of the mounting holes 132 is parallel to the axis of the height adjustment component 2. The mounting holes 132 are used to place the workpiece, and the diameter of the mounting holes 132 gradually decreases from near the height adjustment component 2 to far away from the height adjustment component 2.

[0042] Reference Figure 1 and Figure 4 The digital micrometer 4 includes a measuring probe 42, an electronic screen 43, and a reset button 44. The measuring probe 42 is slidably connected to the digital micrometer 4, and the electronic screen 43 is used to display measurement data. The measurement principle of the digital micrometer 4 is as follows: The digital micrometer 4 is raised above the workpiece using the height adjustment component 2; the lower end of the measuring probe 42 of the digital micrometer 4 contacts the surface of the mounting support plate 13; the reset button 44 of the digital micrometer 4 is pressed, and the value displayed on the electronic screen 43 returns to zero (at this time, the reference plane is the upper surface of the mounting support plate 13); the workpiece is placed below the digital micrometer 4; the lower end of the measuring probe 42 contacts the end face of the gear shaft away from the gear; the electronic screen 43 displays the displacement of the measuring probe 42 relative to the reference plane in real time, which is the absolute axial value between the lower end face of the gear and the end face of the shaft. Digital micrometers are existing technology and will not be described in detail here.

[0043] The implementation principle of a detection device for detecting the axial position of a gear shaft according to an embodiment of this application is as follows: The operator selects the corresponding mounting hole 132 on the mounting support plate 13 according to the diameter of the gear shaft to be measured and places the workpiece there. When the workpiece is a through gear structure and the lower end of the shaft protrudes a long distance, the installation height is pre-adjusted by the lifting assembly 12: the spring pin 123 is released, and the lifting block 122 is slid upward in the lifting support cylinder 121 to the required position, so that the distance between the mounting support plate 13 and the base plate 11 is greater than the length of the lower end of the workpiece. The spring pin 123 is then reinserted to lock the position of the lifting block 122. The auxiliary support column 131 moves upward synchronously along the auxiliary support cylinder 111 to provide stable support. The rotating clamping adjustment component 53 drives the first clamping block 51 and the second clamping block 52 to move towards each other in the support slide groove 141, while simultaneously sliding the first telescopic block 511 and the second telescopic block 521 to the outside of the corresponding mounting hole 132, clamping the workpiece shaft to keep it in a vertical state with the end face of the shaft to be measured facing upward. The rotating height adjustment component 2 drives the support block 15 to rise and fall along the support rod 112, causing the slide rod 151 and the lateral adjustment mechanism 3 to make fine adjustments to the overall height. The rotating drive rod 321, through the meshing of the drive gear 3211 and the driven gear 3231, drives the lateral adjustment component 323, causing the lateral adjustment block 31 to move horizontally along the slide rod 151, so that the measuring probe 42 of the digital micrometer 4 is accurately positioned at the center of the workpiece's end face to be measured. After zeroing the digital micrometer 4 with the upper surface of the mounting support plate 13 as a reference, the measuring probe 42 is lowered to contact the workpiece end face. The electronic screen 43 displays the absolute axial position value of the end face, and the gear position deviation is determined by comparing it with the preset value. The entire testing process directly adapts to workpieces of different shaft diameters through the clamping component 5 and the mounting hole 132, without the need for additional pads.
