[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0019] Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0020] refer to Figure 1 The utility model discloses a device for detecting the inner spline hole of a half-axle gear, comprising a platform 1, on which a support plate 2 is vertically arranged, and the support plate is arranged on a side close to the platform, and a position for placing the half-axle gear is reserved. A movable plate 3 capable of vertical reciprocating motion is arranged on the support plate 2, and a floating probe 4 is arranged on the movable plate 3. The movable plate can reciprocate in the vertical direction, driving the floating probe to rise and fall, thereby adjusting the distance between the floating probe and the half-axle gear, so that the floating probe can be extended into the half-axle gear to achieve the purpose of measuring the inner hole. A positioning seat 5 is arranged on the platform 1 and below the movable plate 3, which moves toward the bottom of the floating probe 4. It should be noted that the positioning seat is preferably annular, and the shaft end of the half-axle gear is inserted into the positioning seat to position the half-axle gear. The gap between the shaft end of the half-axle gear and the positioning seat is set so that the half-axle gear can freely enter and exit the positioning seat.

[0021] Furthermore, in order to increase the stability between the locating seat and the half-shaft gear, a circle of elastic balls is arranged on the inner wall of the locating seat. Specifically, the balls can be connected to the inner wall of the locating seat through springs or spring leaves. At the same time, the balls and springs or spring leaves are embedded in the inner wall of the locating seat. Part of the arc surface of the balls is located in the locating seat. Under the action of the balls, the half-shaft gear can be tightly fixed to avoid or reduce the shaking of the half-shaft gear in the locating seat during movement.

[0022] Furthermore, the platform 1 is provided with a first slide rail 6. As one embodiment, the first slide rail is arranged in parallel with the support plate, the positioning seat is located below the floating probe, the first slide rail 6 is provided with a placement plate 7, and the placement plate 7 is provided with a plurality of positioning seats 5. The positioning seats 5 are arranged in columns or rows. According to the setting situation, the positioning seats are arranged along the length direction of the placement plate, that is, along the direction in which the first slide rail is set. Multiple rows or columns can be set according to the actual situation. A dislocation cylinder 8 is provided on one side of the placement plate 7 to drive the placement plate 7 to move along the first slide rail 6, driving the positioning seat 5 to move toward the bottom of the floating probe 4 in sequence, thereby measuring multiple half-shaft gears in sequence and increasing the measurement efficiency. In order to ensure the stability of the placement plate during movement, two or more first slide rails can be provided as needed, and they are parallel to each other.

[0023] Furthermore, in order to facilitate the placement of the half-axle gear on the mounting seat, the first slide rail 6 is arranged on the translation plate 9, and the translation plate 9 is arranged on the platform 1 through the second slide rail 10. The platform 1 is provided with a translation cylinder 11 for driving the translation plate 9 to move along the second slide rail 10, and the first slide rail 6 and the second slide rail 10 are arranged vertically. It should be noted that the translation cylinder drives the translation plate to move away from or close to the support plate, so as to facilitate the manipulator to clamp the half-axle gear to the positioning seat. The movement direction of the translation plate is perpendicular to the movement direction of the placement plate, that is, the second slide rail is arranged perpendicular to the support plate. In order to increase the stability of the translation plate during movement, two or more second slide rails are provided, and they are parallel to each other.

[0024] Furthermore, in order to make the offset cylinder drive the placement plate to move without affecting the movement of the translation cylinder, a positioning bar 12 is provided in the middle of the placement plate 7, one end of which extends out of one side of the placement plate 7. The cylinder seat of the offset cylinder 8 is fixed on the platform 1 or the translation plate 9, and the output end is fixed on the plate surface of the positioning bar 12. When the offset cylinder is started, it drives the placement plate to move along the first slide rail. At the same time, when the translation cylinder is started, it will move with the offset cylinder and the placement plate and other structures, so that the movement of the translation cylinder and the offset cylinder does not interfere with each other.

[0025] Furthermore, in order to facilitate installation and disassembly, the second slide rail 10 and the support plate 2 are both fixed on the pad 13, and the pad 13 is fixed on the platform 1. At the same time, the cylinder seat of the translation cylinder is also fixed on the pad.

[0026] Furthermore, a third slide rail 14 is vertically arranged on the support plate 2, the movable plate 3 is arranged on the third slide rail 14, and a lifting cylinder 15 with an output end fixed on the movable plate 3 is arranged on the support plate 2. It should be noted that: two or more third slide rails 14 can be arranged as needed and are parallel to each other to ensure the stability of the movable plate when it moves up and down. The cylinder seat of the lifting cylinder is fixed on the support plate, and the output end is fixed on the top of the movable plate. The movable plate is driven up and down by the lifting cylinder, and then the floating probe is driven to move up and down, extending in and out from the center of the half-shaft gear.

[0027] Furthermore, in order to better fix the floating probe, a mounting frame 16 is provided on the plate surface of the movable plate 3 , and the floating probe 4 is arranged on the mounting frame 16 .

[0028] Furthermore, in order to accurately measure or control the distance of the floating probe moving up and down, and the position of the floating probe in the inner hole of the half-shaft gear, a displacement sensor 17 is provided on the movable plate 3, and the floating probe 4 is connected to the displacement sensor 17, and the floating probe 4 is arranged downward. Specifically: the displacement sensor is fixed on the mounting frame and connected to the floating probe.

[0029] When using this utility model, according to Figure 1 As shown, when there are two positioning seats, the robot puts two workpieces (such as half-axle gears) into the positioning seats at the same time, and the translation cylinder pushes the translation plate to move the workpieces into the detection position; the lifting cylinder moves the floating probe into the inner hole of the first workpiece to detect the workpiece size; after the measurement is completed, the measurement structure status is reported.

[0030] The lifting cylinder drives the floating probe to rise, and the offset cylinder moves another workpiece to the detection position, and the floating probe repeats the detection action; the translation cylinder moves the workpiece out to the robot's material picking position, waiting for the robot to grab it and put in the next group of workpieces.
