Description

Technical Field

[0001] The utility model belongs to the technical field of concentricity detection equipment, and particularly relates to a concentricity detection equipment positioning device. Background Art

[0002] Concentricity, also known as coaxiality, refers to the relative position relationship between the central axis of one circular component and the central axis of another circular component. Ideally, the two axes completely coincide. In the fields of mechanical engineering and precision instrument manufacturing, it is very important to ensure precise concentric alignment between components. It directly affects the stability of rotating equipment, reduces wear, improves work efficiency and extends service life. Concentricity detection equipment is a special instrument used to measure the degree of concentricity. This type of equipment usually includes key parts such as positioning devices, measuring sensors, and data processing systems. The role of the positioning device is to stabilize and correctly align the object being measured to ensure the accuracy of the measurement.

[0003] The positioning mechanism of the existing concentricity detection equipment positioning device is fixed and cannot be adjusted. It can only position cylinders of a specific diameter and can only be used for workpieces of a specific size, which limits the versatility and flexibility of the equipment. Different positioning devices are required for workpieces of different diameters, and a set of positioning devices is required for each diameter of cylinder, which increases inventory costs and replacement costs. In scenarios where frequent replacement and inspection of workpieces of different sizes are required, fixed-size positioning devices will lead to reduced operating efficiency. Utility Model Content

[0004] In view of this, the utility model aims to provide a concentricity detection equipment positioning device to address the deficiencies in the prior art. The positioning device can be quickly adjusted and adapted to cylinders of different diameters. The device can be applied to workpieces of various diameters, thereby improving the scope of application and utilization of the equipment. The time for replacing the positioning device is reduced, the detection process is accelerated, and the flexibility and efficiency of the production line are improved.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a concentricity detection equipment positioning device, including a positioning platform, a fixed plate is arranged on the left side of the upper end of the positioning platform, a sliding plate is slidably arranged on the right side of the interior of the positioning platform, the right side of the fixed plate and the left side of the sliding plate are both provided with frame plates that are rotated by a rotating column, a hand wheel is welded and fixed on the right end of the rotating column on the right side, rectangular plates are respectively arranged on the opposite inner sides of the two frame plates, four positioning columns are slidably arranged inside the two rectangular plates, and linkage moving mechanisms that drive the positioning columns to move are respectively arranged inside the two frame plates, and the linkage moving mechanisms The structure includes two rotating frames respectively slidably arranged inside the two frame plates, four connecting frames are rotatably connected inside the two rotating frames, rotating seats are respectively arranged on the outer ends of the eight sliding columns, and the eight connecting frames are respectively rotatably connected to the inner parts of adjacent rotating seats, screw rods 1 are rotatably arranged on the opposite outer sides of the two rectangular plates, the two rotating frames are respectively threadedly connected to the adjacent screw rods 1, and auxiliary rotating components 1 are respectively arranged on the outer ends of the two screw rods 1, and the auxiliary rotating components 1 include knobs respectively arranged on the outer ends of the two screw rods 1, and multiple evenly distributed anti-slip protrusions are arranged on the outer arc surfaces of the knobs.

[0006] As a further improvement of the utility model, two support plates corresponding to the left and right positions are provided at the lower end of the positioning platform, and a driving mechanism for driving the sliding plate to move is provided between the two support plates. The driving mechanism includes a screw rod 2 rotatably arranged between the two support plates, the sliding plate is threadedly connected to the screw rod 2, and an auxiliary rotating component 2 is provided at the right end of the screw rod 2. The auxiliary rotating component 2 includes a hand wheel 2 arranged on the right side of the screw rod 2.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0008] First, by placing the cylinder to be positioned between two rectangular plates, and then rotating handwheel two, screw rod two rotates to drive the rectangular plate on the sliding plate to move left, and cooperate with the fixed plate to quickly limit the left and right sides of the cylinder.

[0009] Secondly, by rotating the knobs on both sides, the screw rod rotates, and then the rotating frames on both sides move away from each other, so that the internal connecting frames rotate and gather together, and then the positioning columns inside the rectangular plate gather together to realize the full-scale positioning of cylinders of different diameters. Then the personnel can also rotate the handwheel to rotate the rotating column, so that the positioned cylinder can be rotated, which is convenient for the personnel to perform concentricity detection on the positioned cylinder. The positioning device can be quickly adjusted and adapted to cylinders of different diameters, can be suitable for workpieces of various diameters, improves the application range and utilization rate of the equipment, and also reduces the time of replacing the positioning device, speeds up the detection process, and improves the flexibility and efficiency of the production line.

[0010] Thirdly, the support plates on both sides of the lower end of the positioning platform can provide stable support when the positioning device is positioning the cylinder, making the positioning device run more stably.

[0011] Fourthly, when a person rotates the knob, the anti-slip protrusion can increase the friction, thereby preventing the person's hand from slipping when in contact with the knob, making it easier for the person to use. BRIEF DESCRIPTION OF THE DRAWINGS
