Description

Technical Field

[0001] The utility model relates to the technical field of roundness detection devices, in particular to a roundness detection device for a transmitter mirror blind cover. Background Art

[0002] Pressure transmitter is a commonly used sensor in industrial production. It is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, oil wells, electricity, ships, machine tools, pipelines and many other industries. Specifically, the pressure transmitter detects the pressure of the working medium in the pipeline, and converts the pressure information into an electrical signal for display and transmission to a remote monitoring and control device. It can convert physical parameters such as pressure of gas, liquid, etc. measured by sensors such as pressure-sensitive elements into standard electrical signals (such as 4-20mADC, etc.) to supply secondary instruments such as indicator alarms, recorders, regulators, etc. for measurement, monitoring and process control.

[0003] After the transmitter mirror blind cover is produced, it needs to be inspected so that it can be connected to the transmitter housing. At present, during the inspection, it is only inspected multiple times by calipers, which is inefficient, and the inspection is randomly stuck in several positions, with low accuracy, resulting in problems in the later assembly, which requires rework or scrapping. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a roundness detection device for a transmitter mirror blind cover which has a simple structure, low cost, is easy to use on site, and is easy to manufacture.

[0007] An auxiliary pressing structure is also installed on the base.

[0008] In this way, during inspection, the mirror blind cover is placed in the arc-shaped supporting opening on the supporting seat, the auxiliary pressing structure assists in pressing down the mirror blind cover, the probe of the micrometer abuts against the mirror blind cover, and then the mirror blind cover is manually rotated. During the rotation process, observe whether the needle of the micrometer is within a reasonable range. If it is within a reasonable range, the roundness of the mirror blind cover is qualified, otherwise it is unqualified.

[0009] Among them, the auxiliary downward pressure structure includes a rotating shaft fixedly installed on the base, a pressure arm is rotatable on the rotating shaft, the pressure arm is L-shaped, one end of the pressure arm is a pressure head, and the other end of the pressure arm is fixedly connected to a compression spring, a top block is fixed on the base, and the end of the compression spring away from the pressure arm is fixedly connected to the top block.

[0010] Wherein, a lower pressing wheel is rotatably mounted on the pressing head end of the pressing arm.

[0011] Wherein, support wheels are rotatably mounted on both sides of the arc-shaped support opening of the support seat.

[0012] Wherein, a threaded seat is fixedly installed on the base, a threaded hole is opened on the threaded seat, a limiting screw is threadedly connected on the threaded seat, and the limiting screw is arranged opposite to the end of the pressure arm away from the pressure head.

[0013] Wherein, two ribs are fixed at both ends of one side of the detection substrate where the support seat is not installed, and the detection substrate is arranged tilted.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0018] like Figure 1-2 As shown, a roundness detection device for a transmitter mirror blind cover 100 comprises a detection substrate 1, a support seat 2 is fixedly mounted at the lower end of the detection substrate, the support seat has an arc-shaped support opening at the beginning, a micrometer 3 is fixedly mounted on the base through a table seat, and a probe 4 of the micrometer passes through the center of the circle where the arc-shaped support opening is located;

[0019] An auxiliary pressing structure is also installed on the base.

[0020] In this way, during inspection, the mirror blind cover is placed in the arc-shaped supporting opening on the supporting seat, the auxiliary pressing structure assists in pressing down the mirror blind cover, the probe of the micrometer abuts against the mirror blind cover, and then the mirror blind cover is manually rotated. During the rotation process, observe whether the needle of the micrometer is within a reasonable range. If it is within a reasonable range, the roundness of the mirror blind cover is qualified, otherwise it is unqualified.

[0021] During implementation, the auxiliary pressing structure includes a rotating shaft fixedly mounted on the base, a pressing arm 5 is rotated on the rotating shaft, the pressing arm is L-shaped, one end of the pressing arm is a pressing head 6, the other end of the pressing arm is fixedly connected to a pressing spring 7, a top block 8 is fixed on the base, and one end of the pressing spring away from the pressing arm is fixedly connected to the top block. Under the action of the pressing spring, the pressing head of the pressing arm will have a force close to the support seat, which is convenient for auxiliary pressing of the mirror blind cover and improves the stability of the process of manually rotating the mirror blind cover.

[0022] During implementation, the pressure head end of the pressure arm is rotatably mounted with a lower pressure wheel 9, thereby reducing friction and improving the smoothness of the rotation of the mirror blind cover.

[0023] During implementation, supports 10 are rotatably mounted on both sides of the arc-shaped support opening of the support seat, thereby reducing friction and improving the smoothness of the rotation of the mirror blind cover.

[0024] During implementation, a threaded seat 11 is fixedly mounted on the base, a threaded hole is provided on the threaded seat, and a limiting screw 12 is threadedly connected to the threaded seat, and the limiting screw is arranged opposite to the end of the pressing arm away from the pressing head. By setting the limiting screw, the rotation of the pressing arm is limited to avoid excessive downward pressure.

[0025] During implementation, two ribs 13 are fixed at both ends of the side of the detection substrate where the support seat is not installed, and the detection substrate is tilted. The detection substrate is tilted to facilitate operation by operators.

[0026] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
