[0004] After the recliner is produced, it is necessary to detect the magnitude of its torque value to judge its qualification. In the prior art, most of them adopt manual rotation of the seat recliner, and judge its qualification by hand feeling or experience. This not only has a high labor intensity for workers, is time-consuming and laborious, and has low work efficiency, but also has low reliability of the detected parameters, and there is no data indicating the magnitude of its torque value, which does not meet the product detection standard. Content of the Utility Model

[0005] The purpose of the utility model is to provide a final detection equipment for a recliner, which solves the problems of low efficiency and low reliability of the detected parameters in the prior art when manually detecting the recliner.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A final detection equipment for a recliner includes a mounting plate arranged inside a control cabinet. One side of the top of the mounting plate is vertically provided with a support frame. The support frame is connected with a mounting frame through a lifting mechanism. An upper servo motor is arranged on the mounting frame. The output shaft of the upper servo motor is vertically downward and is drivingly connected with a vertically arranged ball spline shaft. An upper torque sensor is arranged on the ball spline shaft. And the bottom end of the ball spline shaft is provided with an upper unlocking head. The upper unlocking head is connected with a calibration assembly for calibrating the upper torque sensor. A quick-change tooling is arranged on the top of the mounting plate. A product placement seat aligned with the upper unlocking head is arranged on the quick-change tooling. One side of the bottom of the quick-change tooling is provided with a lower servo motor through a connecting frame. The output shaft of the lower servo motor is vertically oriented towards the product placement seat and is drivingly connected with a lower unlocking head through a vertically arranged unlocking shaft. A lower torque sensor is arranged on the unlocking shaft. The top of the lower unlocking head rotates through the product placement seat.

[0008] A further technical solution is that the lifting mechanism includes a lifting cylinder. The lifting cylinder is arranged at the top of the support frame. The mounting frame is slidably connected to the support frame through a slide rail, and the output end of the lifting cylinder is connected to the mounting frame.

[0009] An even further technical solution is that the calibration component includes a weight. A horizontally arranged connecting rod is connected to the side wall of the upper unlocking head. A pulley is rotatably arranged on the side wall of the support frame through a pulley frame. The weight is connected to one end of the connecting rod far away from the upper unlocking head through a steel wire rope, and the steel wire rope is arranged on the pulley.

[0010] An even further technical solution is that a code scanner gun and an unlocking head placement seat are arranged on one side of the top of the quick-change tooling.

[0011] An even further technical solution is that an industrial control computer is arranged inside the control cabinet. A touch screen is connected to the outer wall of the control cabinet. The touch screen, the upper servo motor, the upper torque sensor, the lower servo motor, the lower torque sensor and the lifting mechanism are all electrically connected to the industrial control computer.

Detailed implementation mode

[0018] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] Embodiment 1:

[0020] Refer to Figures 1 to 4It is shown that a final inspection device for an angle adjuster of the present utility model includes a mounting plate 2 provided inside a control cabinet 1. On one side of the top of the mounting plate 2, a support frame 4 is vertically provided. The support frame 4 is connected with a mounting frame 5 through a lifting mechanism. An upper servo motor 6 is provided on the mounting frame 5. The output shaft of the upper servo motor 6 is vertically downward and is drivingly connected with a vertically arranged ball spline shaft 7. An upper torque sensor 8 is arranged on the ball spline shaft 7, and an upper unlocking head 9 is provided at the bottom end of the ball spline shaft 7. A concave hole adapted to the top of the angle adjuster is provided at the bottom of the upper unlocking head 9 to better press the angle adjuster. The upper unlocking head 9 is connected with a calibration component for calibrating the upper torque sensor 8. By setting the calibration component, the value of the upper torque sensor 8 can be calibrated to ensure the numerical accuracy; a quick-change tooling 3 is provided at the top of the mounting plate 2, and a product placement seat 10 aligned with the upper unlocking head 9 is provided on the quick-change tooling 3; on one side of the bottom of the quick-change tooling 3, a lower servo motor 12 is provided through a connecting frame 11. The output shaft of the lower servo motor 12 is vertically oriented towards the product placement seat 10 and is drivingly connected with a lower unlocking head 14 through a vertically arranged unlocking shaft 13. The lower unlocking head 14 matches the shaft hole. A lower torque sensor 15 is arranged on the unlocking shaft 13, and the top of the lower unlocking head 14 rotates through the product placement seat 10; during use, the angle adjuster is placed on the product placement seat 10, the lower unlocking head 14 is connected with the shaft hole of the angle adjuster, the lifting mechanism drives the mounting frame 5 to descend, and then drives the upper unlocking head 9 to descend, so that the upper unlocking head 9 presses the angle adjuster. The lower servo motor 12 works to drive the lower unlocking head 14 connected with the shaft hole to rotate in a specified direction to achieve the unlocking purpose. At this time, the upper servo motor 6 works according to the set parameters to drive the upper unlocking head 9 to rotate through the ball spline shaft 7, and then drives the internal gear to rotate to achieve the running-in of the angle adjuster. After the running-in is completed, both the upper servo motor 6 and the lower servo motor 12 return to the origin. The upper servo motor 6 works to drive the upper unlocking head 9 to rotate through the ball spline shaft 7, and then drives the internal gear and the annular control member of the angle adjuster to rotate until the inner peripheral groove on the annular control member is engaged with the engaging protrusion on the external gear and is stuck, when the internal gear stops rotating, the upper servo motor 6 stops working. When the inner peripheral groove on the annular control member is engaged with the engaging protrusion on the external gear and is stuck, the external gear and the brake cam cooperate to lock the angle adjuster. During the detection process, if the upper servo motor 6 works to drive the upper unlocking head 9 to rotate through the ball spline shaft 7 and the situation where the internal gear stops rotating does not occur, it means that the inner peripheral groove on the annular control member does not engage with the engaging protrusion on the external gear, then it is determined that the annular control member is not installed in the angle adjuster. On the contrary, if the situation where the internal gear stops rotating occurs, it is determined that the annular control member is installed. In this way, it can be detected whether there is an annular control member in the angle adjuster. At the same time, when the inner peripheral groove on the annular control member is engaged with the engaging protrusion on the external gear and the annular control member is stuck, the internal gear has a maximum rotation angle relative to the plate frame. By recording the rotation angle of the annular control member driven by the upper servo motor 6 working, the maximum adjustment angle of the angle adjuster can be detected.After completing the detection of the presence or absence of the annular control part inside the angle adjuster and the detection of the maximum adjustment angle of the angle adjuster, the lower servo motor 12 operates to unlock the angle adjuster. The upper servo motor 6 and the lower servo motor 12 both return to the origin. At this time, the lower servo motor 12 operates in the corresponding torque mode set, and drives the lower unlocking head 14 to rotate through the shaft hole of the unlocking shaft 13 to drive the brake cam to unlock the angle adjuster. During the unlocking process, the lower torque sensor 15 detects the torque. When the torque of the lower servo motor 12 reaches the maximum torque set by the angle adjuster, the angle reached by the angle adjuster at the maximum torque is the maximum unlocking angle. At the same time, through the detection of the lower torque sensor 15, the unlocking torque and the critical unlocking torque can be obtained. After completing the detection of the maximum unlocking angle, unlocking torque and critical unlocking torque of the angle adjuster, the upper servo motor 6 drives the upper unlocking head 9 to rotate a certain angle clockwise and counterclockwise respectively through the ball spline shaft 7 according to the corresponding working parameters set, and then drives the internal gear of the angle adjuster to rotate a certain angle clockwise and counterclockwise respectively, and detects the torque during rotation through the upper torque sensor 8. Whether there is jamming inside the angle adjuster can be judged by the detected torque magnitude. Then the upper servo motor 6 and the lower servo motor 12 both return to the origin, that is, the final detection of the angle adjuster is completed. Through the above structure, the functions of running-in the angle adjuster, detecting the presence or absence of the annular control part inside the angle adjuster, detecting the maximum adjustment angle of the angle adjuster, detecting the maximum unlocking angle, unlocking torque and critical unlocking torque of the angle adjuster, and detecting whether there is jamming inside the angle adjuster can be realized, improving the practicability of the device.

During actual use, the lifting cylinder 16 extends and retracts through the output end of the controller, and then pushes the mounting frame 5 to move up and down along the slide rail 17.

[0023] Refer to Figure 2 As shown, the calibration component includes a weight 18. A horizontally arranged connecting rod 19 is connected to the side wall of the upper unlocking head 9. A pulley 21 is rotatably arranged on the side wall of the support frame 4 through a pulley frame 20. The weight 18 is connected to the end of the connecting rod 19 far from the upper unlocking head 9 through a steel wire rope 22. The steel wire rope 22 is arranged on the pulley 21. By comparing the weight of the weight 18 after calculation with the measured value of the torque sensor, the calibration of the torque sensor is completed. By arranging the pulley 21 through the pulley frame 20, a lane change is provided for the pulling direction of the steel wire rope 22.
