[0008] As one of the preferred solutions of the present invention, the limit block is arranged behind the limit step, and the moving pipe sets another damping production point in the pipe processing groove of the lower pressing block. The driving mechanism drives the upper pressing plate to move downward, and the pressing protrusion presses the pipe downward until it stops when it contacts the top of the limit block.

One side of the pipeline is ventilated and connected to a gas flow meter. The driving mechanism drives the upper pressing block to press the damping downward. When the preset flow rate is reached, the driving mechanism stops, thereby realizing the automatic suppression of the damping. The pipeline can be moved to complete all the damping on the pipeline with high consistency. At the same time, when the first damping of the pipeline is completed, the limit block is placed, and the subsequent damping can be made without measuring the gas flow every time, which is convenient and quick.

[0024] The driving mechanism composed of stepper motor, coupling and lead screw is used to move the upper pressure block up and down, which can achieve high-precision control, ensure the accuracy of damping, and achieve the purpose of precise flow control. At the same time, the height of the stepper motor can be adjusted through the support seat and slider, which improves the convenience of pipeline processing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The technical solution of the present invention is further described below through specific embodiments. The pipeline damping automatic manufacturing device and automatic manufacturing method of the present invention are not only applicable to intelligent gas chromatography detection systems, but also can be used in pipelines of various instruments that need to manufacture damping.

[0033] Example 1

[0034] like Figure 1-4 As shown, the automatic pipeline damping manufacturing device provided in this embodiment includes a driving mechanism 10, an upper pressing block 15, a lower pressing block 16 and a gas flow meter 40, the lower pressing block 16 is provided with a pipeline processing groove, and the upper pressing block 15 is provided with a pressing protrusion; the gas flow meter 40 is arranged on the pipeline 30 to be damped, and one side of the pipeline 30 is ventilated; the gas flow meter 40 is electrically connected to the driving mechanism 10, the pipeline 30 extends into the pipeline processing groove of the lower pressing block, and is positioned at a damping manufacturing point, the driving mechanism 10 drives the upper pressing block 15 to move downward, and the pressing protrusion of the lower pressing block 16 presses the pipeline downward until the gas flow meter 40 reaches the required flow value, and the driving mechanism 10 stops.

[0035] The driving mechanism 10 used in this embodiment includes a stepper motor 11, a coupling 12, a screw 13, a connecting splint 14 and a base 17. The upper pressing plate 15 is fixed at the bottom of the connecting splint 14, and the lower pressing plate 16 is fixed at the top of the base 17. The stepper motor 11 drives the upper pressing plate 15 to move up and down through the coupling 12, the screw 13 and the connecting splint 14. The gas flow meter 40 is electrically connected to the stepper motor. When the gas flow reaches the required flow value, the stepper motor stops working, and the damping production point of the pipeline is completed, thereby realizing automatic damping production with high precision. Optionally, the driving mechanism can also be a manual pressing mechanism or a hydraulic system. Any power mechanism that can provide the upper pressing plate to press downward is within the protection scope of this patent.

[0036] In actual operation, the installation heights of pipelines are all different. In order to meet the processing requirements of pipelines at different heights, a height adjustment mechanism 50 is also provided on one side of the driving mechanism. The height adjustment mechanism 50 includes a support seat 51 and an optical axis 52. The optical axis 52 is installed on one side of the support seat 51 through an optical axis 55 bracket. A slider 53 is provided on the optical axis 52. One side of the slider 53 is connected to the stepper motor 11 through a motor bracket 54. The height of the stepper motor 11 is adjusted by adjusting the slider 53 to meet the processing requirements of different pipelines. At the same time, in order to improve the stability of the support seat, a support plate 56 is also provided on the side of the support seat 51 facing away from the optical axis 52. Preferably, a rotating wheel can be installed at the bottom of the support seat 51 to facilitate the movement of the driving mechanism and increase the convenience in actual use.

[0037] This embodiment can automatically produce damping by measuring the gas flow rate of the pipeline multiple times, that is, each time the pressure is pressed, the gas flow rate is used as the judgment standard to reach the required flow rate value, such as Figure 3 and Figure 4 As shown, automatic and accurate production of pipeline damping can be achieved, which has higher precision and consistency than manual hammering.

[0038] To further improve the convenience of operation, after the first pipeline damping is completed, that is, when the driving mechanism 10 stops moving, a limit groove is formed between the upper pressing block 15 and the lower pressing block 16, and one or two limit blocks 30 are arranged in the limit groove, such as Figure 5 and Figure 6 As shown, the pipeline processing groove of the lower pressing block 16 is provided with limiting steps on both sides, and the pressing protrusion of the upper pressing block 15 is provided with corresponding steps on both sides. The limiting block 30 is set on the limiting step, and the height of the limiting block 30 is equal to the distance L between the limiting step and the step when the driving mechanism stops. After the limiting block 30 is set on the limiting step, the moving pipeline 30 sets another damping production point in the pipeline processing groove of the lower pressing block 16, and the driving mechanism 10 drives the upper pressing plate 15 to move downward, and the pressing protrusion presses the pipeline downward until it stops when it contacts the top of the limiting block 30.

[0039] The height of the limit block 30 is determined by the pipeline damping requirements. If different damping is produced, only the limit block needs to be adjusted and replaced, which is convenient and reliable, and the quality can also be monitored during the process.

[0040] Example 2

[0041] This embodiment also provides a method for automatically making a pipeline damper, using the automatic pipeline damper making device described in Embodiment 1, and comprising at least the following steps:

[0042] S1, connect the pipeline to be damped to the gas measuring instrument and ventilate one side of the pipeline;

[0043] S2, inserting the pipe to be damped into the pipe processing groove of the lower pressing block and positioning it to a damping manufacturing point;

[0044] S3, the driving mechanism drives the upper pressing block to move downward, and the pressing protrusion of the upper pressing block presses the pipeline downward until the gas flow meter reaches the required flow rate, and the driving mechanism stops moving;

[0045] S4, setting a limit block in the limit groove between the upper pressing block and the lower pressing block;

[0046] S5, moving the pipeline to place another damping manufacturing point into the pipeline processing groove of the lower pressing block;

[0047] S6, the driving mechanism drives the upper pressing block to move downward until the upper pressing block contacts the top of the limit block, and the driving mechanism stops moving;

[0048] S7, move the pipeline in sequence, put different damping production points into the pipeline processing groove of the lower pressing block, and repeat step S6 until the damping production of the entire pipeline is completed.

[0049] It can be seen that the automatic pipeline damping production device and method described in the present invention can realize batch production of damping, ensure the consistency and interchangeability of damping, reduce workload, shorten working hours, and improve efficiency.

[0050] The embodiments of the present invention are described in detail above.
