Description

Technical Field

[0001] The utility model belongs to the field of component detection, and in particular relates to an arc measuring device. Background Art

[0002] With the rapid development of the economy, cars are becoming more and more popular and entering every household. Cars have added more functions on the basis of providing convenient travel, such as sunroofs. Open the car sunroof and use its superior negative pressure ventilation principle to filter the air in the car to protect the health of the driver and passengers.

[0003] Existing skylights are all electrically opened, so they need to be matched with guide rails. Due to installation requirements, the guide rails need to be made into an arc shape. Currently, the industry uses manual bending to form the arc of the guide rails, which has low precision. Moreover, the guide rails are hollow structures, which can easily cause the hollow part to be flattened, affecting the installation of the rollers.

[0004] A Chinese utility model patent with announcement number CN205593471U discloses a device for detecting the curvature of a bending rod of a car luggage rack. The device includes a gauge body, a base plate and a dial indicator for placing the automobile bending rod. The gauge body and the dial indicator are both arranged on the base plate. The dial indicator includes a meter body, a sleeve and a measuring rod. The meter body is connected to the sleeve, and the measuring rod extends into the meter body along the sleeve. The gauge body is provided with a measuring through hole. One side of the gauge body contacts the meter body, and the other side of the gauge body constitutes a bending rod placement area. The end of the measuring rod extends into the bending rod placement area along the measuring through hole of the gauge body. In the bending rod placement area where the curvature of the bent aluminum rod is matched, the outer wall of the bending rod squeezes the measuring rod during placement, forcing the measuring rod to retract into the gauge body. When the car luggage rack is completely placed in the bending rod placement area and close to the inner wall of the gauge body, the dial indicator measures the gap between the inner wall of the gauge body and the bending rod and reads the curvature value. Then the worker observes the reading of each dial indicator. According to the error value set for the production of the bending rod, if the dial indicator reading is within the error value range, it is a qualified product.

[0005] However, the device's inspection fixture body is arc-shaped and needs to fit the product to be inspected, and the solution can only be used to inspect products with one length dimension or arc dimension, with poor versatility. It also requires manual reading of the dial indicator and judgment of whether the measurement results meet the design requirements, and the measurement is slow. Summary of the invention

[0006] In order to solve the problems existing in the above-mentioned prior art, the purpose of the utility model is to provide a radian measuring device which can meet the radian measurement needs of products with various length sizes or radian sizes.

[0008] As can be seen from the above, the curvature measuring device of the utility model has two end positioning parts, and the accommodation depth of the end positioning parts is adjustable, so that when both ends of the product to be measured are positioned stably, products with various curvatures can be measured by the detection member. In addition, each end positioning part also includes a first abutting wall, and the spacing between the first abutting walls of the two end positioning parts is adjustable, which can meet the needs of curvature measurement of products of different lengths.

[0009] A further solution is that each end positioning portion also includes a supporting wall, each supporting wall is opposite to the first abutting wall along the length direction, each supporting wall is close to the accommodating portion relative to the corresponding first abutting wall, and each supporting wall is provided with a supporting portion for supporting the product to be detected.

[0010] As can be seen from the above, the support part on the support wall makes the product more stable during measurement, convenient to operate and low in cost.

[0016] As can be seen from the above, the container is made of silicone or rubber, which can effectively prevent the product from being scratched or damaged, and the height of the support wall can be changed according to the curvature of the product.

[0017] A further solution is that each end positioning portion is also provided with a first adjustment position and a second adjustment position, and each first adjustment position is closer to the accommodating portion relative to the second adjustment position; two positioning members are also detachably installed at the end positioning portion, and the two positioning members are symmetrically arranged on both sides of the accommodating portion with the accommodating portion as the center, and each first abutment wall is located on the corresponding positioning member, and each positioning member is installed at the corresponding first adjustment position at the same time, or is installed at the corresponding second adjustment position at the same time.

[0020] It can be seen from the above that the first positioning cavity surrounded by the second positioning side wall, the first positioning side wall and the first abutting wall can allow products with a relatively narrow width to be stably placed on the placement table for inspection.

[0021] A further solution is that a first baffle and a second baffle which are opposite to each other along the width direction of the detection position are further provided on the accommodating portion, and the first baffle, the second baffle and the upper surface of the bottom wall of the accommodating portion form a second positioning cavity.

[0022] It can be seen from the above that the provision of the first baffle and the second baffle can effectively improve the stability of product placement.
