DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings to make it easier to understand and grasp.

[0020] like Figure 1 As shown, the utility model describes a vehicle manual shift lever detection device, comprising a gear selection mechanism 1, a gear lifting and shifting mechanism 2, a gear shift lever positioning and clamping mechanism 3, a workbench 4, a touch screen (not shown in the figure), a PLC controller (not shown in the figure) and a marking machine (not shown in the figure); the gear selection mechanism 1 and the gear shift lever positioning and clamping mechanism 3 are both installed on the workbench 4, the gear selection mechanism 1 is horizontally U-shaped, and the mechanism can realize gear selection action when driven by a motor; the gear lifting and shifting mechanism 2 is vertically inverted U-shaped, and can realize gear lifting and shifting action.

[0021] like Figure 1 and Figure 2As shown, the cylinder 11 and the reducer 12 are fixedly mounted on the workbench 4 via a mounting plate; the actuator of the cylinder 11 is hinged to the connecting plate 13; the connecting plate 13 is fixedly connected to the reducer output shaft 15. The output end of the gear selection motor 110 is connected to the input end of the reducer 12. The controller issues a command to drive the gear selection motor 110 to rotate, and the reducer 12 realizes deceleration and changes the direction of power transmission. An output end of the reducer 12 is connected to the gear selection arm 111, and drives it to move as required. Figure 2 As shown, it rotates around the Y-axis, thereby realizing the gear selection action; the other output end of the reducer 12 transmits the same speed to the pulley 17 through the synchronous belt (pulley 14, belt 16, pulley 17), and further transmits it to the coupling A18 and encoder A19, so that the encoder A19 is used to synchronously record the steering, angle and other information of the gear selection arm 111, and transmit the information to the controller, which is then displayed on the touch screen.

[0022] like Figure 3 As shown, the gear lifting and shifting mechanism 2 mainly includes a gear lifting assembly 24 and a gear shifting actuator 210, both of which are installed on the gear shifting arm 25; the input end of the ball screw 21 is connected to the output end of the gear shifting motor 23, and the output end of the ball screw 21 is connected to the output end of the gear shifting motor 23. Figure 4 The back of the connecting plate B 249 is hinged. The controller sends a command to drive the gear shifting motor 23 to rotate, and the ball screw 21 converts the motor's rotational motion into linear motion, pushing the back of the fixed plate B 249, and then pushing the gear lifting assembly 24 and the gear shifting arm 25 around. Figure 1 As shown, point A realizes rotation around the X axis, thereby realizing the gear shifting action.

[0023] like Figure 4 As shown, the lifting cylinder 241 is installed on the connecting plate B 2410, and its executive part is connected to the displacement sensor connecting plate 242 and the cylinder body of the pushing cylinder 243 in sequence; the executive part of the pushing cylinder 243 is connected to the slide connecting plate 245, the force sensor A 246, and the U-shaped slot 247 in sequence; therefore, when the executive part of the lifting cylinder 241 is lifted up and down, it can drive the displacement sensor connecting plate 242, the pushing cylinder 243, the pushing cylinder slide 244, the slide connecting plate 245, the force sensor A 246, and the U-shaped slot 247 to move up and down synchronously; when the pushing cylinder 243 is extended and retracted, it can drive the slide connecting plate 245, the force sensor A 246, and the U-shaped slot 247 to move forward and backward.

[0024] like Figure 5As shown, the lifting cylinder 2101 is installed on the horizontal plate 2102, and its telescopic rod is connected to the transition plate 2103; the rotating cylinder 2104, the sensor connector 2107, the force sensor B 2106, the U-shaped hook 2105, and the transition plate 2103 are connected in sequence; when the lifting cylinder 2101 is in operation, the part from the transition plate 2103 to the U-shaped hook 2105 can be lifted up and down under the guidance of the guide column 2109 and the guide sleeve 2108; when the rotating cylinder 2104 is in operation, it drives the part from the U-shaped hook 2105 to the sensor connector 2107 to rotate.

[0025] When in use, the worker places the gear lever to be tested on the Figure 1 The clamping and positioning mechanism shown in the figure mainly relies on Figure 6 The positioning block A 31 and the positioning block B 35 are used to locate the bottom of the test piece. After that, the "Clamp" button on the touch screen is manually pressed, and the rotary cylinder A 33 and the rotary cylinder B 37 are simultaneously actuated to control the clamping arm A 32 and the clamping arm B 38 to rotate to the positions shown in FIG. Figure 6 At the position shown, the bottom of the shift lever to be tested is pressed tightly; at the same time, the push column cylinder 39 is energized to control the push column 34 to be pushed out and just stuck under the shift lever to prevent it from swinging at will.

[0026] Confirm the gear selection, gear engagement and gear lifting parameters through the touch screen, and press the "Start" button on the workbench with both hands to start the automatic test program. The above-mentioned top column cylinder 39 drives the top column 34 to withdraw downward, so that the bottom of the gear shift lever of the test piece is in a free state; at the same time, Figure 5 The lifting cylinder 2101 is energized to drive the transition plate 2103 to move downward under the push of the guide column 2109, that is, the U-shaped hook 2106 moves downward and blocks the shift lever handle of the column;

[0027] Furthermore, the controller controls Figure 2 The gear selection motor 110 rotates and drives the gear selection arm 111 to swing around the Y axis to the target position after passing through the reducer 12. Figure 7 At the center line of gear 1 as shown; stay for 1 second and record the value measured by force sensor B 2106, which is the gear selection force for gear 1-2; at the same time, record the value of encoder A19, which is the gear selection angle for gear 1-2.

[0028] Then, the controller drives the rotating cylinder 2104 to rotate the U-shaped hook 2105 90 degrees around the Z axis to prepare for the gear shifting. The controller controls the gear shifting motor 23 to rotate, and through the ball screw 21, pulls the gear lifting assembly 24 and the gear shifting arm 25 to A (as shown in FIG. Figure 1When the shift arm 25 rotates in the positive direction around the X-axis, the 1st gear can be engaged, and when it rotates in the negative direction around the X-axis, the 2nd gear can be engaged. After reaching the specified position, it stays for 1 second and records the value measured by the force sensor B 2106, which is the 1-2 gear engaging force. At the same time, the value of the encoder B 27 is recorded, which is the 1-2 gear selecting angle.

[0029] The controller then controls the shift motor 23 to rotate in the reverse direction, returning the shift mechanism to the 1-2 gear selection position. Once in the target position, the controller activates the rotary cylinder 2104, rotating the U-shaped hook 2105 90° around the Z axis, returning it to the selected gear position. The controller then controls the shift motor 110 to rotate in the reverse direction, which, after passing through the reducer 12, drives the shift arm 111 to its initial position around the Y axis. The lift column cylinder 39 then raises the lift column 34, securing the bottom of the gear lever under test and allowing it to be tested in the next gear. The same procedure applies to gears 3-6.

[0030] When you need to test reverse gear (such as Figure 7 The steps of testing 1-6 gears are similar, except that: ① before the gear selection motor 110 is driven, the gear lifting action is completed first, that is, the controller controls the gear selection motor 110 to Figure 4 As shown, the push-out cylinder 243 is in action, and its piston rod extends to push the slide connecting plate 245, the force sensor A 246, and the U-shaped slot 247 forward, so that the U-shaped slot 247 is just stuck in the shift lever's shift-lifting part; then the controller controls the lifting cylinder 241 to retract, and finally drives the U-shaped slot 247 and the shift lever's shift-lifting part upward to complete the shift-lifting action; and records the value of the displacement sensor 2410, which is the shift-lifting stroke, and at the same time records the value of the force sensor A 246, which is the shift-lifting force. ② Before engaging the gear, remove the shift-lifting force, that is, after reaching the R gear selection position, exhaust the shift-lifting cylinder 241 to make it free, and record the R gear selection force and angle. The other test steps are similar for gears 1-6.

[0031] like Figure 2 The piston rod of cylinder 11 is hingedly connected to connecting plate 13, forming a slider-crank mechanism. Reducer 15 is fixedly attached to connecting plate 13, allowing connecting plate 13 to rotate synchronously with the gear selector arm 111, converting this rotation into movement of the piston rod of cylinder 11. A magnetic piston within cylinder 11 interacts with magnetic sensors mounted on either side of the cylinder barrel to detect the two extreme positions of gear selector mechanism 1, preventing it from swinging beyond its limits.

[0032] like Figure 3 As shown, the sensing rod 29 installed on the shift arm 25 senses the limit sensors (not shown) installed on both sides of the dial 28, which can detect the two extreme positions of the shift lifting and shifting mechanism 2 to prevent the mechanism from swinging beyond the limit.

[0033] The test data of encoder A 19, encoder B 27, force sensor A 246, force sensor B2106, and displacement sensor 2410 in this device can all be displayed in real time on the touch screen. If the gear selection, gear lifting, and gear engagement angles / displacements are within the allowable range, and the force values ​​measured by the two force sensors are also within the allowable range, the product test has passed and the marking machine will immediately print a "qualified" label. If the data is abnormal, an alarm window will immediately pop up on the touch screen and the marking machine will not operate.

[0034] After all gear tests are completed, the controller directly drives the rotary cylinder A 33 and the rotary cylinder B 37 to drive the clamping arm A 32 and the clamping arm B 38 to rotate 90 degrees, loosening the bottom of the shift lever; at the same time, the push column cylinder 39 is driven to retract, so that the push column withdraws. The worker removes the shift lever after testing and replaces the shift lever to be tested. The above test steps are repeated to start the test of the next shift lever, and the cycle is repeated.

[0035] From the above description, it can be seen that the utility model adopts a PLC controller to control the rotation of the drive motor or the movement / rotation of the cylinder, which further drives the action of the gear selection mechanism, the gear lifting and shifting mechanism and the positioning and clamping mechanism, and can fully simulate the actual operation of the shift lever by personnel to each gear position. Its action is stable and reliable, and the test force consistency is good, which can ensure the repeatability of the test action and data, thereby ensuring the integrity and reliability of the test data; in addition, the angles of gear selection and shifting can be set and adjusted through the touch screen, and the position of the positioning and clamping device of the device can be disassembled and adjusted; therefore, this detection device is suitable for testing different models of gear levers, has strong versatility, and is suitable for promotion within the industry.

[0036] Of course, for those skilled in the art, the technical solutions disclosed in this utility model are not limited to the details of the above exemplary descriptions. Without departing from the spirit or basic features of this utility model, this utility model can be implemented in other specific forms. Therefore, no matter from which point of view, the above specific examples should be regarded as exemplary and non-restrictive. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection of the claims of this utility model.
