[0002] The splines for constant velocity joints need to be quality inspected during production, and during the inspection process, ring gauges are needed to inspect them.

[0003] Generally, when inspecting external splines, workers usually manually take a ring gauge that matches the spline and put the ring gauge on the outer surface of the spline to achieve the purpose of inspecting the spline. However, the above operation steps are cumbersome and require the spline and the ring gauge to be taken separately and the two to be manually plugged in, which is inefficient, time-consuming and greatly increases the labor intensity of the operator.

[0011] Preferably, a rotation groove for accommodating the base is provided at the bottom of the turntable, and a second motor for driving the turntable to rotate is provided in the base.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] refer to Figure 1 As shown, the utility model provides a spline ring gauge inspection device for a constant velocity joint, comprising: a liftable inspection member, a turntable 2 and a base 1 are sequentially arranged below the inspection member, the turntable 2 is rotatably mounted on the base 1, a plurality of inspection areas are distributed in a circular array on the top of the turntable 2, and the plurality of inspection areas pass through the bottom of the inspection member sequentially based on rotation.

[0024] Combination Figure 4-Figure 5 As shown, the top of the turntable 2 is provided with placement grooves 17 in a circular array, and each detection area is formed in a corresponding placement groove 17 , and a positioning inner spline seat 18 for positioning can be detachably installed in each placement groove 17 .

[0025] As mentioned above, when using the detection part, turntable 2 and base 1 provided by the utility model, multiple spline workpieces are positioned in the corresponding placement grooves 17 by positioning the inner spline seat 18. When the turntable 2 rotates on the base 1, it drives multiple spline workpieces to pass under the detection part in turn. When the spline workpiece is under the detection part, the detection part descends to detect the spline workpiece. After the inspection, the processing workshop resets to allow the next spline workpiece to enter under the detection part. During this process, the spline workpiece after inspection can be unloaded, and the new spline workpiece can be placed in the placement groove 17. A robot arm can be added to load and unload the spline workpiece. The above steps are repeated to realize the automatic inspection of the spline workpiece by the equipment.

[0026] Further, in order to facilitate the replacement of the positioning inner spline seat 18, refer to Figure 4As shown, two positioning posts 19 are longitudinally symmetrically arranged at the bottom of the positioning inner spline seat 18, and positioning holes 20 are symmetrically opened in each placement groove 17, and each positioning post 19 is respectively inserted into the corresponding positioning hole 20. The positioning inner spline seat 18 in the placement groove 17 can be positioned through the positioning holes 20 and the positioning posts 19, and the spline workpiece can be positioned in the placement groove 17 at this time, so that the inner splines on the ring gauge seat 10 correspond to the outer splines of the spline workpiece one by one, which is convenient for the ring gauge seat 10 to detect the spline workpiece.

[0027] In the present utility model, combined with Figure 3 As shown, the detection component of this embodiment is provided with a mounting column 7, a ring gauge seat 10 and a contact sensor 15 in sequence from top to bottom. A mounting hole 14 for accommodating the mounting column 7 is opened at the top of the ring gauge seat 10. The ring gauge seat 10 is movably mounted on the bottom end of the mounting column 7 through the mounting hole 14. The contact sensor 15 is arranged at the bottom of the mounting hole 14, and the contact sensor 15 can abut against the bottom end of the mounting column 7.

[0030] 1. The ring gauge seat 10 is directly mounted on the spline workpiece. At this time, the spline workpiece is qualified;

[0031] 2. The ring gauge seat 10 abuts against the spline workpiece.

When the mounting column 7 contacts the contact sensor 15, the equipment automatically resets, and the contact sensor 15 sends an electrical signal to the external terminal, so that the terminal sends an alarm, and the maintenance personnel directly take out the unqualified spline workpiece.

[0032] In the present utility model, combined with Figure 2As shown, the longitudinal direction of the outer side of the base 1 of this embodiment is sequentially provided with a column 4 and a lifting column 5 from bottom to top, a rectangular telescopic hole 13 is opened at the top of the column 4 along the axial direction to accommodate the lifting and lowering of the lifting column 5, a screw 12 is rotatably installed in the rectangular telescopic hole 13 along the axial direction, a threaded hole 11 for accommodating the screw 12 is opened at the bottom of the lifting column 5, a first motor 3 for driving the screw 12 to rotate is provided at the bottom of the column 4, and a top plate 6 connected to the top of the mounting column 7 is provided at the top of the lifting column 5.

[0033] As described above, when using the column 4, lifting column 5 and screw 12 provided by the utility model, the lifting column 5 can be lifted and lowered on the column 4 through the rectangular telescopic hole 13, and the lifting column 5 can be automatically lifted and lowered in the rectangular telescopic hole 13 through the screw 12 and the threaded hole 11. The screw 12 can be driven to rotate by the first motor 3, thereby driving the ring gauge seat 10 to approach the spline workpiece, thereby facilitating the ring gauge seat 10 to detect the spline workpiece.
