Description

Technical Field

[0001] The invention belongs to the technical field of carbon fiber plate thickness measurement, in particular to a device for measuring the thickness of a carbon fiber plate. Background Art

[0002] The background technology of carbon fiber plate thickness measurement mainly involves the field of composite material manufacturing and quality control. Carbon fiber plate has the characteristics of high strength, light weight and corrosion resistance;

[0003] When measuring the thickness of the carbon fiber plate, since it is necessary to use a laser to detect it, the position of the carbon fiber plate needs to be limited. The use of a support will block part of the position of the carbon fiber plate, resulting in inaccurate thickness detection results of the carbon fiber plate;

[0004] In view of this, a device for measuring the thickness of a carbon fiber plate is proposed. Summary of the Invention

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0006] In view of the following technical problems in the existing technology: when measuring the thickness of the carbon fiber plate, since laser detection is required, the position of the carbon fiber plate needs to be limited. Then, when the position is limited, the four edges of the carbon fiber plate will become loose under long-term action, affecting the measurement accuracy. The use of a support will block part of the position of the carbon fiber plate, resulting in inaccurate thickness detection results of the carbon fiber plate.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a device for measuring the thickness of a carbon fiber plate, comprising a complete device, a measuring cavity and a thickness measuring mechanism;

[0008] The measuring cavity is milled on the complete equipment, a door panel is hinged at the opening of the measuring cavity, a control button is installed on the complete equipment, and the thickness measuring mechanism is arranged in the measuring cavity;

[0009] The thickness measuring mechanism includes an auxiliary component and a measuring component, wherein the auxiliary component is located above the measuring component;

[0010] The auxiliary assembly includes a bidirectional screw, a guide rod, an adjustment frame, a load-bearing arm and a contact pad. The bidirectional screw is hinged in the complete equipment, the guide rod is fixed in the complete equipment, the bidirectional screw and the guide rod are arranged in parallel, a pair of internal threaded sleeves are threaded on the bidirectional screw, a pair of guide sleeves are slidably connected on the guide rod, the sides of the internal threaded sleeves and the guide sleeves are jointly installed with a load-bearing arm, the other end of the load-bearing arm is installed with a contact pad, the four contact pads touch the edges of the four corners of the carbon fiber plate, and the adjustment frame is slidably installed outside the load-bearing arm;

[0011] The measuring unit includes a threaded rod 1, a guide column, a threaded rod 2, a laser sensor housing and a convex ring. The threaded rod 1 is hinged in the complete equipment, the guide column is fixed in the complete equipment, a pair of internal threaded sleeves 2 are threadedly transmitted on the threaded rod 1, a pair of guide sleeves 2 are slidably connected on the guide column, and a supporting frame is jointly configured on the internal threaded sleeves 2 and the guide sleeves 2. The middle position of the supporting frame is hinged with the threaded rod 2, the threaded rod 2 is threaded with the internal threaded sleeve 3, and the laser sensor housing is installed on the top surface of the internal threaded sleeve 3.

[0012] As an optimal technical solution for a device for measuring the thickness of a carbon fiber plate, a driving motor is provided at one end of the bidirectional screw, and a lower positioning plate and an upper positioning plate are installed on opposite surfaces of a pair of the internal threaded sleeve and the guide sleeve, the upper positioning plate is located above the lower positioning plate, and the upper positioning plate is parallel to the lower positioning plate, and a linkage frame is provided on the lower positioning plate for telescopic movement, a linkage plate is installed at the position where the linkage frame extends out of the lower positioning plate, and an arc plate is installed at the edge of the linkage plate, and when the laser sensor housing is displaced to the position of the adjustment frame, the convex ring will act on the arc plate to enable the position of the linkage plate to be lifted upward.

[0013] As an optimal technical solution for a device for measuring the thickness of a carbon fiber plate, a spring is connected between the linkage plate and the lower positioning plate. When the convex ring and the arc plate do not correspond in position, the spring can assist the linkage plate in resetting.

[0014] As an optimal technical solution for a device for measuring the thickness of a carbon fiber plate, a gear is hinged on the back of the upper positioning plate, and the gear is engaged with a linkage frame, wherein the linkage frame is milled with teeth on a side facing the gear, and a U-frame is provided on the upper positioning plate for horizontal telescopic movement, and the bottom surface of the U-frame is milled with teeth, and the U-frame is engaged with the gear. When the linkage plate is acted upon to perform telescopic movement, the linkage frame engages with the gear, causing the gear to rotate, and the gear rotates to engage the U-frame for horizontal telescopic movement.

[0015] As an optimal technical solution for a device for measuring the thickness of a carbon fiber plate, a driven plate is installed on the upper part of the U frame, and the driven plate is connected to the adjustment frame. The lateral movement of the U frame can link the driven plate and the adjustment frame to move together.

[0016] As a preferred technical solution for an apparatus for measuring the thickness of a carbon fiber plate, a protrusion is provided on the side of the contact pad facing the carbon fiber plate, wherein the protrusion can increase the contact friction between the contact pad and the carbon fiber plate.

[0017] As an optimal technical solution for a device for measuring the thickness of a carbon fiber plate, the adjustment frame consists of an arc portion and a U portion. The U portion telescopically moves on the carrying arm, the U portion is connected to the driven plate, and the arc portion is installed at the opening of the U portion. The U portion can ensure and adjust the parallel state of the carbon fiber plate when measuring, thereby improving the measurement accuracy.

The drive motor 2 controls the rotation of the threaded rod 2, and a guide plate is installed on the side of the carrier frame. The side of the internal threaded sleeve 3 is in contact with the inner edge of the guide plate, so that the internal threaded sleeve 3 will not rotate during the position movement.

[0019] As an optimal technical solution for a device for measuring the thickness of a carbon fiber plate, a laser displacement sensor is installed in the laser sensor housing, and a set of threaded rods 1 are also installed on the top of the inner edge of the measuring cavity. The threaded rods 1 do not require guide columns, and the subsequent measurement of the carbon fiber plate is performed through the relative laser displacement sensor.

[0020] As an optimal technical solution for measuring the thickness of carbon fiber plates, a convex ring is installed on the outer periphery of the laser sensor housing, which is used to act on the linkage plate to perform lifting movement when the laser sensor housing moves to the corresponding position of the adjustment frame.

[0021] Beneficial effects of the present invention:

[0022] 1. This device for measuring the thickness of carbon fiber plates enables the laser sensor housing to move in the X and Y directions through threaded rods 1 and 2, which facilitates all-round thickness measurement of carbon fiber plates. At the same time, when the laser sensor housing moves to the position of the adjustment frame, the adjustment frame partially blocks the carbon fiber plate, resulting in a blind angle during measurement. The convex ring acts on the linkage plate through the arc plate. The linkage plate, under the linkage of the linkage frame, gear and U frame, enables a single adjustment frame at the corresponding position to not limit the carbon fiber plate. Since the corner position detection is fast and is restricted by the other three, the carbon fiber plate will not fall at one corner and affect the accuracy of the measurement structure, thereby enabling the carbon fiber plate to be accurately measured without blind angles.

[0023] 2. The device for measuring the thickness of the carbon fiber plate enables the carbon fiber plate to be placed horizontally under the restriction of the arc and the contact pad, and the arc can be adjusted to the same height for the lower part of the carbon fiber plate, thereby improving the accuracy of the measurement structure.

The purposes and other advantages of the present invention can be realized and obtained through the structures particularly pointed out in the description and the drawings.
