Description

Technical Field

[0001] The utility model relates to a positioning component and belongs to the technical field of positioning devices. Background Art

[0002] For products in the 3C industry with a diameter of less than 30mm, a circular shape, and irregular internal structures, the assembly yield is very low during the assembly of parts because the products cannot be accurately positioned, and fast and convenient assembly cannot be achieved. The current assembly methods are generally the following two:

[0003] 1: Manual assembly, using human eyes to identify the direction and assemble two parts. This method has low assembly yield and low efficiency, and increases labor costs;

[0004] 2: The shape is elastically positioned by silicone pads, and the product is positioned by the elastic deformation of the silicone pads. The disadvantage is that the silicone pads are affected by the material properties, and are frequently deformed and worn after a period of use, resulting in positioning failure, frequent replacement, unstable positioning, and high later maintenance costs. Summary of the invention

[0005] The purpose of the utility model is to overcome the shortcomings of the above-mentioned traditional technology and provide a positioning component, which can realize the precise positioning of the product to be positioned, quickly and accurately, with high efficiency, and will not damage the product to be positioned.

[0011] The front end of the correction shaft is provided with a positioning opening.

[0012] The positioning block is provided with a through hole for accommodating the correction shaft to pass through. The correction shaft passes through one end of the through hole, and a first plug is provided at the other end of the through hole. A buffer spring is provided between the first plug and the correction shaft.

[0013] A pressure head is arranged on one side of the positioning block close to the product placement slot, and the bottom of the pressure head and the bottom of the positioning block are on the same plane.

[0014] Stop blocks are respectively arranged at both ends of the base, and tension springs are respectively arranged between the stop blocks and the left positioning component and the right positioning component.

[0015] The positioning block is provided with a through hole for accommodating the tension spring, the tension spring passes through one end of the through hole, the other end of the through hole is provided with a second plug, and the stopper is provided with a groove for accommodating the tension spring.

[0016] The upper end of the pneumatic clamp has two clamping parts that can be opened and closed. The two clamping parts have the same structure and are symmetrically arranged. The outer sides of the upper ends of the two clamping parts are respectively provided with clamping grooves, which correspond to the support columns.

[0017] Due to the adoption of the above technical scheme, compared with the prior art, the advantages of the utility model are as follows: when the utility model is operated, the pneumatic clamp operates to open the two clamp parts, and the two clamp parts push the support columns on both sides to move to both sides respectively, thereby driving the positioning blocks on both sides to move to both sides, and placing the product to be positioned in the product placement groove, and then, the two clamp jaws of the pneumatic clamp are closed, and the positioning blocks on both sides move inward under the action of the tensioning spring, and the pressure head presses the base of the product to be positioned to limit the product to be positioned in the Z-axis direction, and the positioning port of the correction shaft clamps the product to be positioned, and limits the product to be positioned in the X-axis and Y-axis directions, thereby realizing precise positioning of the product to be positioned, which is fast, accurate and efficient; during the process, the buffer spring plays a buffering role when the correction shaft moves, preventing the correction shaft from rigidly contacting the product to be positioned and damaging the product to be positioned.
