Description

Technical Field

[0001] This utility model relates to the field of induction hardening technology, specifically a height detection device suitable for wheel hub bearings. Background Technology

[0002] Wheel bearings are a key component of automobiles. Their main function is to bear weight and provide precise guidance for the rotation of the wheel hub. They require high hardness and wear resistance, and since wheel bearings must withstand long-term loads, they also need a certain degree of toughness. Induction hardening can meet these processing requirements. Induction hardening allows for precise control of the hardened layer depth (e.g., treating only the surface 1-3mm), ensuring surface hardness while preserving the toughness of the core. During induction hardening, the height detection of the workpiece is critical. Even slight deviations can cause collisions with the inductor, damaging both the workpiece and the inductor, increasing production costs, and reducing efficiency. Therefore, a height detection device needs to be designed. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a height detection device suitable for wheel hub bearings. This device is mounted on a workpiece gripper and primarily detects the gripper's descent height via a position detection switch. The workpiece height is determined by comparing the actual descent height with the set descent height, thus achieving workpiece height detection.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a height detection device suitable for wheel hub bearings, including a mounting plate, a height detection switch, several pressing mechanisms, and a lifting plate and a pressing plate arranged sequentially below the mounting plate; the mounting plate is connected to the lifting plate through several lifting guide rods, and a position detection plate is provided at the upper end of one of the lifting guide rods; the height detection switch is connected to the mounting plate and is used to detect the height of the position detection plate; the pressing plate is used to press against the workpiece and is connected to the lifting plate through several pressing connecting rods; the pressing mechanism is connected to the mounting plate, and the lower end of the pressing mechanism is used to hold the lifting plate.

[0005] A further improvement is that the mounting plate has a ring structure, and the mounting plate is provided with connecting holes for connecting workpiece grippers. The outer edge of the mounting plate is provided with a plurality of first ears corresponding to the lifting guide rods and a plurality of second ears corresponding to the pressing mechanism. The first ears are provided with first mounting holes for installing the lifting guide rods, and the second ears are provided with second mounting holes for installing the pressing mechanism.

[0006] A further improvement is that: the lifting plate has a ring structure, and the diameter of the lifting plate is larger than the diameter of the mounting plate; the lifting plate is provided with a number of third mounting holes corresponding to the lifting guide rods, and the inner edge of the lifting plate is provided with a number of third ears corresponding to the pressing connecting rods; the third ears are provided with fourth mounting holes for installing the pressing connecting rods.

[0007] A further improvement is that: two lifting guide rods and two pressing mechanisms are provided, and they are evenly distributed on the mounting plate. The two lifting guide rods are arranged longitudinally opposite each other, and the two pressing mechanisms are arranged laterally opposite each other.

[0008] A further improvement is that the lifting guide rod includes a sleeve and a central rod. The sleeve is fixedly inserted into the mounting plate, and the central rod is slidably inserted into the sleeve. The lower end of the central rod extends out of the sleeve and is fixedly connected to the lifting plate, while the upper end of the central rod extends out of the sleeve and expands to form a limiting block.

[0009] A further improvement is that the pressing mechanism includes an adapter plate, one end of which is provided with a fifth mounting hole for connecting to the mounting plate, and the other end of which is provided with a pressing cylinder, and the piston rod of the pressing cylinder is connected downward to a pressing rod.

[0010] A further improvement is that the height detection switch is located on the side of the mounting plate and opposite to the position detection plate.

[0011] A further improvement is that the pressure plate is circular.

[0012] A further improvement is that the pressure plate has a Y-shaped structure.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention indirectly measures the workpiece height by detecting the displacement of the position detection plate through a position detection switch, avoiding damage to parts caused by direct detection; it adopts a quick-change pressure plate, which facilitates machine tool changeover and improves processing efficiency; after the pressure plate presses down on the workpiece, it is tightened again by a cylinder to ensure data accuracy and also plays an auxiliary positioning role, ensuring the accuracy of detection and processing, promoting production and improving economic efficiency.

[0040] See Figure 5 As shown, the mounting plate 1 has a ring structure. The mounting plate 1 is provided with a connecting hole 11 for connecting the workpiece gripper. The outer circle of the mounting plate 1 is provided with a number of first ears 12 corresponding to the lifting guide rod 4 and a number of second ears 14 corresponding to the pressing mechanism 7. The first ears 12 are provided with a first mounting hole 13 for installing the lifting guide rod 4, and the second ears 14 are provided with a second mounting hole 15 for installing the pressing mechanism 7.

[0046] The working principle of this utility model is as follows:

[0047] During operation, after the workpiece is transported to the corresponding position by the conveyor chain, the workpiece gripper moves the height detection device to the corresponding position and then descends. First, the pressure plate contacts the workpiece, and then the workpiece presses against the pressure plate, causing the lifting plate to rise, which in turn raises the lifting guide rod and the position detection plate until the workpiece gripper descends to the set position. The pressure cylinder guide rod extends to press and fix the workpiece. The position detection switch transmits the movement distance and compares the data transmitted by the position detection switch with the system set data to detect the workpiece height. If the workpiece height is within a reasonable range after comparison, the workpiece gripper picks up the workpiece to proceed to the next process; otherwise, the system reports an error and the workpiece is manually removed.
