Description

Technical Field

[0001] The utility model relates to the technical field of workpiece detection, in particular to a hole position detection device for a carbon fiber tube. Background Art

[0002] Carbon fiber reinforced plastic (CFRP) is a material formed by compounding carbon fiber and resin under certain pressure and temperature. It has the characteristics of high strength, light weight, corrosion resistance and long life. The unique properties of carbon fiber reinforced plastics have led to an increasing demand for carbon fiber tubes, especially in applications where weight is an important factor. Carbon fiber tubes are increasingly replacing steel tubes, titanium tubes and aluminum tubes. In addition, carbon fiber tubes are made of a combination of carbon fiber braids and unidirectional carbon fiber fabrics. They have excellent torsional properties and compressive strength and are also suitable for high torque applications.

[0003] Currently in the semiconductor field, carbon fiber tubes are mainly used in LCD and chip assembly process equipment. They replace bulky metal robotic arms, significantly reduce amplitude, improve stability and production efficiency, and have high strength, light weight, low thermal expansion coefficient, fatigue resistance and high temperature resistance. In practical applications, the side walls of carbon fiber tubes usually need to be processed with holes, which are generally through holes. In the process of mechanical processing, the shape of the holes is easily deformed, which affects the stability and reliability of the carbon fiber tubes. They cannot meet production requirements and can only be scrapped.

[0004] CN217384037U provides a special inspection tool for carbon fiber tubes, which is a rectangular plate provided with a semi-enclosed groove; the structure of the semi-enclosed groove is adapted to the structure of the carbon fiber tube to be inspected; at least two hole spacing positioning columns are provided at the bottom of the semi-enclosed groove. The special inspection tool for carbon fiber tubes realizes the rapid and effective detection of the size and root end flatness of the carbon fiber tube, improves the detection efficiency and accuracy, and reduces the detection cost. However, the inspection tool cannot detect whether the hole position of the carbon fiber tube is deformed.

[0005] Therefore, it is of great significance to provide a device that can accurately detect whether the hole position of the carbon fiber tube is deformed. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a hole position detection device for a carbon fiber tube, which can quickly detect whether the hole is deformed, handle abnormal products in time, reduce the scrapping of parts, reduce production costs, and improve production efficiency.

[0007] To achieve this purpose, the utility model adopts the following technical solutions:

[0008] The utility model provides a hole position detection device for a carbon fiber tube, the hole position detection device comprising a detection platform;

[0009] The detection platform is provided with a first support rod and a second support rod, and the axial directions of the first support rod and the second support rod are both perpendicular to the upper surface of the detection platform;

[0010] A mounting base is provided on one side of the upper end of the first support rod, and the axis of the mounting base is parallel to the upper surface of the detection platform;

[0011] A through hole is provided in the second support rod, and the axial direction of the through hole is parallel to the upper surface of the detection platform;

[0012] One end of the carbon fiber tube is connected to the mounting base on the first support rod, and the other end passes through the through hole on the second support rod, and the axial direction of the carbon fiber tube is parallel to the upper surface of the detection platform;

[0013] A hole is provided on the outer wall of the carbon fiber tube, a detection accessory is provided in the hole, and an infrared rangefinder is provided above the detection accessory;

[0014] The infrared rangefinder is connected to a vertical bracket through a connecting rod. The vertical bracket is arranged on the detection platform and the axial direction of the vertical bracket is perpendicular to the upper surface of the detection platform.

[0015] The hole position detection device provided by the utility model fixes the carbon fiber tube and controls the axial direction of the carbon fiber tube to be parallel to the upper surface of the detection platform through the arrangement of the first support rod and the second support rod. One end of the carbon fiber tube is connected to the mounting base on the first support rod, and the other end passes through the through hole on the second support rod. If the hole position on the carbon fiber tube is deformed, the roundness error increases, and the detection accessory will also be deformed after being inserted into the hole position, and the horizontality of the upper end face of the detection accessory will deteriorate. Therefore, an infrared rangefinder is used to measure the vertical distance between two points on the same circumference and the same diameter on the upper end face and the infrared rangefinder. If the difference in the vertical distance exceeds 0.4mm, it means that the hole position is severely deformed, the product is unqualified, and needs to be repaired.

[0016] In the utility model, the material of the detection fitting is polyetheretherketone PEEK.

[0017] Preferably, the detection accessory is a T-shaped structure; the upper end surface of the detection accessory is circular; and the lower end of the detection accessory is a cylindrical structure.

[0020] Preferably, the diameter of the upper end surface is 8-10 mm, for example, it can be 8 mm, 8.2 mm, 8.4 mm, 8.6 mm, 8.8 mm, 9 mm, 9.2 mm, 9.4 mm, 9.6 mm, 9.8 mm or 10 mm, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0021] Preferably, the hole is circular in shape.

[0022] Preferably, the diameter of the hole is 2-4 mm, for example, it can be 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3 mm, 3.2 mm, 3.4 mm, 3.6 mm, 3.8 mm or 4 mm, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0023] In the utility model, the cylindrical structure of the detection accessory is inserted into the hole of the carbon fiber tube, so the diameter of the lower end of the detection accessory should match the diameter of the hole, that is, the matching tolerance of the two is ±0.1mm.

[0024] Preferably, the mounting base comprises a base platform and a connecting tube; one end of the connecting tube is connected to the base platform via a screw, and the other end is connected to the carbon fiber tube.

[0025] Preferably, the side wall of the first support rod is connected to a right-angled side of the triangular bracket, and the other right-angled side of the triangular bracket is arranged on the detection platform.

[0026] Preferably, the triangular bracket is in the shape of an isosceles right triangle.

[0027] The operation process of the hole position detection device provided by the utility model for detecting the hole positions contained in the carbon fiber tube is as follows:

[0028] Connect one end of the carbon fiber tube to the connecting tube with glue, and pass the other end through the through hole on the second support rod. Fasten the connecting tube and the base platform with screws, and finally make the axial direction of the carbon fiber tube parallel to the upper surface of the detection platform. Install the detection accessories into the hole to be tested of the carbon fiber tube, and use an infrared rangefinder to measure the vertical distance between two points on the same circle and the same diameter on the upper end surface and the infrared rangefinder. If the difference in vertical distance exceeds 0.4mm, it means that the hole has undergone severe deformation, the product is unqualified, and needs to be repaired.

[0029] Compared with the prior art, the beneficial effects of the utility model are:

[0030] The hole position detection device provided by the utility model can quickly detect whether the hole position is deformed, handle abnormal products in time, reduce the scrapping of parts, reduce production costs, and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
