Description

Technical Field

[0001] The utility model relates to the technical field of outer diameter detection, in particular to an output shaft outer diameter detection device. Background Art

[0002] In the field of vehicle manufacturing, output shafts of transmission systems such as gearboxes and axles are key basic components. The machining accuracy of their outer diameter directly determines the fitting quality with bearings, wheel hubs, gears and other components, and further affects the stability, reliability, noise level and service life of the whole vehicle transmission.

[0003] For such large and heavy-duty output shafts, the "go / no-go gauge" method is usually used to inspect the outer diameter size in the final process. First, according to the design tolerance, a precision go / no-go gauge ring with a "go end" (maximum material size) and a "no-go end" (minimum material size), which is referred to as a ring gauge for short, is manufactured. During detection, an operator manually carries the metal ring gauge and sleeves it horizontally onto the outer diameter surface of the shaft. If the "go end" can pass smoothly and the "no-go end" cannot pass, the outer diameter is determined to be qualified. The ring gauge is usually a solid steel part, and high-frequency and repeated manual handling, lifting and alignment operations are performed on the production line or at the detection station, which greatly consumes the physical strength of operators and results in extremely high labor intensity. Therefore, there is an urgent need for an output shaft outer diameter detection device to solve the above problems. Summary of Invention

[0004] The utility model provides an output shaft outer diameter detection device aiming at the deficiencies of the prior art.

[0005] The utility model is realized through the following technical solutions, and provides an output shaft outer diameter detection device, which comprises a worktable, a limiting mechanism installed on the worktable for limiting a workpiece, and a detection mechanism installed above the worktable for detecting the outer diameter of the workpiece; the limiting mechanism comprises a limiting stop bar with both ends fixed to the worktable and two limiting adjustment rods installed on the limiting stop bar with adjustable spacing; the detection mechanism comprises a horizontally arranged cross bar, a ring gauge located below the cross bar, and two guide pull rods whose lower ends are connected with the ring gauge, and the upper ends of the two guide pull rods are connected through a connecting rod after penetrating through the cross bar.

[0006] Preferably, two sleeves are sleeved on the limiting stop bar, each sleeve is fixed to the limiting stop bar respectively through a first tightening bolt, and one end of each of the two limiting adjustment rods is correspondingly fixed to one sleeve. By loosening the first tightening bolt, the position of the sleeves is adjusted to change the spacing between the two limiting adjustment rods, the spacing between the two limiting adjustment rods is adjusted according to the outer diameter of the bottom of the workpiece, and the workpiece is limited by the limiting stop bar and the two limiting adjustment rods.

[0007] Preferably, the crossbar is provided with a long through hole for the guide rod to pass through, and the upper end of each guide rod is connected to the connecting rod through the upper connecting seat, and the lower end is connected to the ring gauge through the lower connecting seat.

[0008] Preferably, the upper end of each guide rod is rotatably connected to the upper connecting seat, and the lower end is rotatably connected to the lower connecting seat. Each guide rod has a limiting rod at the bottom and a handwheel at the top. Rotating the handwheel causes the guide rod to rotate, changing the direction of the limiting rod. When the limiting rod needs to pass through the elongated through hole, rotating the handwheel makes the limiting rod parallel to the elongated through hole. When the ring gauge needs to be limited, rotating the handwheel makes the limiting rod perpendicular to the elongated through hole, placing the limiting rod above the crossbar. The cooperation between the crossbar and the limiting rod limits the ring gauge. When the ring gauge moves up and down, the crossbar guides the ring gauge, limiting its movement in the horizontal direction and facilitating alignment between the ring gauge and the workpiece.

[0011] Preferably, a lifting ring for connection with a lifting device is provided on the connecting rod. When inspecting the outer diameter of the workpiece, the lifting ring is connected to the hook of the lifting device, and the ring gauge is moved up and down by the lifting device.

[0012] Preferably, each end of the crossbar is connected to the workbench via a vertical pole.

[0013] Preferably, the upright is movably connected to the worktable. Specifically, two parallel slide rails are provided on the worktable, perpendicular to the direction of the crossbar. A slider that can move along each slide rail is installed on each rail. The two sliders are respectively fixed to one upright, and a second tightening bolt is installed on each slider to secure it. After adjusting the positions of the upright and crossbar, the sliders are fixed using the second tightening bolts. This allows for easy adjustment of the crossbar position according to different workpieces, adapting to the outer diameter inspection requirements of different workpieces.

[0014] Preferably, the worktable is a non-powered roller worktable.

[0015] Preferably, the non-powered idler roller worktable includes a support and a plurality of parallel idler rollers rotatably mounted on the support, wherein the limiting stop bar is parallel to the idler rollers.

[0019] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0020] like Figure 1-7 As shown, this utility model includes a worktable, a limiting mechanism installed on the worktable to limit the workpiece 4, and a detection mechanism installed above the worktable for detecting the outer diameter of the workpiece 4.

[0021] The limiting mechanism includes a limiting stop 1 fixed at both ends to the worktable and two adjustable limiting rods 2 mounted on the limiting stop 1. Two sleeves 3 are fitted onto the limiting stop 1, each sleeve 3 being fixed to the limiting stop 1 by a first tightening bolt. One end of each of the two limiting adjusting rods 2 is fixed to one sleeve 3. By loosening the first tightening bolt, the position of the sleeves 3 is adjusted to change the distance between the two limiting adjusting rods 2. The distance between the two limiting adjusting rods 2 is adjusted according to the outer diameter of the bottom of the workpiece 4, thus limiting the workpiece 4 through the limiting stop 1 and the two limiting adjusting rods 2.

[0022] The detection mechanism includes a horizontally arranged crossbar 5, a ring gauge 6 located below the crossbar 5, and two guide rods 7 whose lower ends are connected to the ring gauge 6. The upper ends of the two guide rods 7 pass through the crossbar 5 and are connected by a connecting rod 8.

[0023] A long through hole 9 is provided on the crossbar 5 for the guide rods 7 to pass through. The upper end of each guide rod 7 is connected to the connecting rod 8 via an upper connecting seat 10, and the lower end is connected to the ring gauge 6 via a lower connecting seat 11. The upper end of each guide rod 7 is rotatably connected to the upper connecting seat 10, and the lower end is rotatably connected to the lower connecting seat 11. Each guide rod 7 has a limiting rod 12 at the bottom and a handwheel 13 at the top. Rotating the handwheel 13 rotates the guide rod 7, which changes the direction of the limiting rod 12. When the limiting rod 12 needs to pass through the long through hole 9, rotating the handwheel 13 makes the limiting rod 12 parallel to the long through hole 9. When the ring gauge 6 needs to be limited, rotating the handwheel 13 makes the limiting rod 12 perpendicular to the long through hole 9, so that the limiting rod 12 is positioned above the crossbar 5. The cooperation between the crossbar 5 and the limiting bar 12 can limit the ring gauge 6. When the ring gauge 6 moves up and down, the crossbar 5 also guides the ring gauge 6, so that the ring gauge 6 is limited in the horizontal direction, which makes it convenient for the ring gauge 6 to be aligned with the workpiece 4.

[0024] In this embodiment, each upper connecting seat 10 is movably connected to the connecting rod 8, and each lower connecting seat 11 is movably connected to the ring gauge 6. Specifically, the movable connection is a bolted connection. Based on the outer diameter detection of different workpiece models 4, the connection positions of the two guide rods 7 and the connecting rod 8 are adjusted, and different models of ring gauges 6 are selected.

[0025] A lifting ring 14 for connecting to a lifting device is provided on the connecting rod 8. When the outer diameter of the workpiece 4 is being inspected, the lifting ring 14 is connected to the hook of the lifting device, and the ring gauge 6 is moved up and down by the lifting device. The lifting device adopts a structure that is not part of the innovation of this utility model, and its specific structure will not be described in detail here.

[0026] The crossbar 5 is connected to the worktable at both ends via uprights 15. In this embodiment, the uprights 15 are movably connected to the worktable. Specifically, two parallel slide rails 16 are provided on the worktable, and the slide rails 16 are perpendicular to the direction of the crossbar 5. A slider 17 that can move along the slide rail 16 is installed on each slide rail 16. The two sliders 17 are respectively fixed to one upright 15. A second tightening bolt is installed on each slider 17 to fix the slider 17. After adjusting the positions of the uprights 15 and the crossbar 5, the sliders 17 are fixed by the second tightening bolts. This allows for easy adjustment of the position of the crossbar 5 according to different workpieces 4 to meet the outer diameter detection requirements of different workpieces 4.

[0027] In this embodiment, the worktable is a non-powered idler roller worktable, which includes a support 18 and a plurality of parallel idler rollers 19 rotatably mounted on the support 18. The limiting stop 1 is parallel to the idler rollers 19. The non-powered idler roller 19 worktable is prior art, and its specific structure will not be described in detail here.

[0028] In practice, the workpiece 4 is transported to the workbench using a lifting device. The workpiece 4 is pushed along the roller 19 so that its bottom rests between the limit stop 1 and the two limit adjustment rods 2. Once the workpiece 4 is in place, the hook of the lifting device is connected to the lifting ring 14 on the connecting rod 8. The handwheel 13 is turned so that the guide rod 7 drives the limit rod 12 to rotate parallel to the elongated through hole 9. The lifting device is then controlled to move the ring gauge 6 downward to inspect the outer diameter of the workpiece 4. After the inspection is completed, the lifting device is controlled to move the ring gauge 6 upward. Once the limit rod 12 has moved above the crossbar 5, the handwheel 13 is turned so that the guide rod 7 drives the limit rod 12 to rotate perpendicular to the elongated through hole 9, thus limiting the ring gauge 6.

[0029] This utility model has a simple structure and is easy to operate, enabling convenient inspection of the outer diameter of large, heavy-duty output shafts, saving time and effort and greatly reducing the labor intensity of workers. The limiting mechanism limits the workpiece 4, ensuring the alignment of the ring gauge 6 with the workpiece 4. The cooperation of the crossbar 5 and guide rod 7 of the inspection mechanism further ensures the alignment of the ring gauge 6 with the workpiece 4. The combination of the limiting mechanism and the inspection mechanism improves the efficiency of workpiece outer diameter inspection.
