[0002] like Figure 1 As shown, the workpiece is called a gear, which includes a square groove at the top, a convex tooth in the middle, and a strip groove at the bottom. After the gear is produced, it needs to be inspected to check whether the position of the convex tooth relative to the square groove and the position of the strip groove meet the requirements. Currently, there is a lack of a device that can quickly complete the above inspections at the same time. Therefore, how to quickly complete the above inspections is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention
[0003] In view of this, the purpose of this utility model is to propose a gear inspection device to solve the problem of how to simultaneously and quickly inspect whether the positional accuracy of the convex teeth and the square groove and the positional accuracy of the strip groove meet the requirements.
[0004] To achieve the above objectives, this utility model provides a gear inspection device, including a base, and further comprising: a first support plate, a second support plate, a clamping assembly, a third support plate, an inspection plate, a bracket, a gauge block, and a limiting assembly, wherein:
[0005] The first support plate, the second support plate, and the third support plate are all disposed on the top of the base, and the second support plate is located between the first support plate and the third support plate;
[0006] The second support plate is provided with a protruding strip for the groove at the bottom of the gear;
[0007] The inspection plate is disposed on the top of the first support plate, and a toothed groove is provided on one side of the inspection plate for engaging with the convex teeth of the gear.
[0008] The clamping assembly is disposed on the top of the third support plate and is used to fix the gear;
[0009] The bracket is disposed above the base, the gauge block is slidably connected to the bracket, the bottom of the gauge block has a square block, the square block is used to cooperate with the square groove on the top of the gear, and the limiting component is used to limit the gauge block.
[0010] A qualified gear can simultaneously satisfy the fit between the groove and the convex strip at the bottom of the gear, the fit between the convex tooth and the tooth groove, and the fit between the square groove and the square block at the top of the gear.
[0011] Optionally, the clamping assembly includes a base frame mounted on the third support plate. The base frame has a handle, and a connecting rod is hinged to the handle. One end of the connecting rod is hinged to a clamping rod, which is slidably connected to the base frame.
[0012] Optionally, the contact sliding portion between the block gauge and the bracket is larger than the width of the square block. The limiting component includes a connecting block disposed on one side of the bracket, and a limiting rod is slidably connected to the connecting block. When the limiting rod is located below the contact sliding portion between the block gauge and the bracket, it plays a supporting and limiting role for the entire block gauge.
[0013] Optionally, handles are provided on both sides of the top of the base.
[0014] When using this device to test the positional accuracy of a gear, firstly, the groove and convex strip at the bottom of the gear are engaged. Then, with the groove and convex strip engaged, observe whether the gear teeth and grooves can be engaged. If they are engaged, the gear is qualified; if they are not engaged, the gear is unqualified. Once the gear teeth and grooves are engaged, the gear is clamped and fixed by the clamping assembly. Then, the limit assembly is controlled to release the limit on the gauge block, allowing the gauge block to slide down naturally. If the square block can slide into the square groove at the top of the gear, the gear is qualified; if the square block is blocked, the positional accuracy is unqualified.
[0015] As can be seen from the above, this device enables simultaneous and rapid inspection of whether the positional accuracy of the convex teeth and the square groove and the positional accuracy of the strip groove meet the requirements, which not only ensures the accuracy of the inspection, but also improves the efficiency of the inspection.

[0025] like Figures 1-4 As shown, a gear inspection device includes a base 1, and further includes: a first support plate 2, a second support plate 3, a clamping assembly, a third support plate 4, an inspection plate 5, a bracket 6, a gauge block 7, and a limiting assembly, wherein:
[0026] The first support plate 2, the second support plate 3 and the third support plate 4 are all disposed on the top of the base 1, and the second support plate 3 is located between the first support plate 2 and the third support plate 4;
[0027] The second support plate 3 is provided with a protrusion 8 for engaging with the strip groove 17 at the bottom of the gear 16;
[0028] The inspection plate 5 is disposed on the top of the first support plate 2, and a toothed groove is provided on one side of the inspection plate 5, which is used to cooperate with the protruding tooth 18 of the gear 16.
[0029] The clamping assembly is disposed on the top of the third support plate 4 and is used to fix the gear 16.
[0030] The bracket 6 is disposed above the base 1, the gauge block 7 is slidably connected to the bracket 6, the bottom of the gauge block 7 has a square block 9, the square block 9 is used to cooperate with the square groove on the top of the gear 16, and the limiting component is used to limit the gauge block 7.
[0031] A qualified gear 16 can simultaneously satisfy the following: the strip groove 17 at the bottom of the gear 16 matches the convex strip 8; the convex tooth 18 of the gear 16 matches the tooth groove; and the square groove at the top of the gear 16 matches the square block 9.
[0032] When using this device to test the position of gear 16, firstly, the strip groove 17 at the bottom of gear 16 is engaged with the convex strip 8. Then, with the strip groove 17 at the bottom of gear 16 engaged with the convex strip 8, observe whether the tooth 18 of gear 16 can engage with the tooth groove. If they engage, it is qualified; if they do not engage, it is unqualified. After the tooth 18 of gear 16 engages with the tooth groove, the gear 16 is clamped and fixed by the clamping assembly. Then, the limit assembly is controlled to release the limit on the gauge block 7, allowing the gauge block 7 to slide down naturally. If the square block 9 can slide into the square groove at the top of gear 16, it means that gear 16 is qualified. If the square block 9 is blocked, it means that the position is unqualified.
[0033] As can be seen from the above, this device enables simultaneous and rapid inspection of whether the positional accuracy of the protruding tooth 18 and the square groove and the positional accuracy of the strip groove 17 meet the requirements, which not only ensures the accuracy of the inspection, but also improves the efficiency of the inspection.
[0034] In some embodiments, the clamping assembly includes a base frame 10, which is mounted on the third support plate 4. A handle 11 is provided on the base frame 10, and a connecting rod is hinged to the handle 11. One end of the connecting rod is hinged to a clamping rod 12, which is slidably connected to the base frame 10. Controlling the swing of the handle 11 can move the clamping rod 12 via the connecting rod, thereby clamping or releasing the gear 16 by the clamping rod 12, preventing the gear 16 from moving during detection.
[0035] In some embodiments, the contact sliding portion between the gauge block 7 and the support 6 is larger than the width of the square block 9. The limiting component includes a connecting block 13 disposed on one side of the support 6, and a limiting rod 14 is slidably connected to the connecting block 13. When the limiting rod 14 is located below the contact sliding portion between the gauge block 7 and the support 6, it supports and limits the entire gauge block 7. When the gauge block 7 needs to fall, the limiting rod 14 is moved away from below the contact sliding portion of the support 6. Without the support of the limiting rod 14, the gauge block 7 will fall due to gravity. When the gauge block 7 needs to be limited, the gauge block 7 is first manually lifted so that the contact sliding portion on the gauge block 7 is above the limiting rod 14, and then the limiting rod 14 is moved below the contact sliding portion on the gauge block 7 to support and limit the gauge block 7.
[0036] In some embodiments, handles 15 are provided on both sides of the top of the base 1. The handles 15 facilitate the movement and other operations of the device.
