Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a shell detection device. Background Art

[0002] The housing is a pipe used to transport liquids or gases. It is typically constructed from multiple layers of composite materials and offers excellent corrosion resistance, pressure resistance, and sealing properties. Currently, housings are manufactured using CNC machine tools to drill holes to ensure concentricity between the holes at both ends, but there is no practical way to verify this. Problems with the CNC machine's spindle can prevent the concentricity of the holes at both ends of the housing from being consistent. The membrane tube in the housing is made of alumina, which is hard but very brittle. Therefore, it is crucial to ensure that the O-rings apply uniform pressure to the tube to provide a seal and secure it. If the concentricity of the upper and lower membrane tube mounting holes deviates, or the gland end face is uneven, the O-rings will apply uneven pressure to the membrane tube, causing the tube to fail sealantly or break, thereby compromising the equipment's effectiveness and resulting in material loss. Using only water for equipment verification during commissioning is insufficient to assess equipment performance; however, testing with materials can result in significant losses if problems are discovered.

[0003] Therefore, there is an urgent need to design a detection device with simple structure and easy operation to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a shell detection device, which effectively solves the problems of the existing penetration drilling of the shell, but no actual detection method to ensure the concentricity of the tube holes at both ends, resulting in inconsistent concentricity at both ends, causing membrane tube sealing failure or membrane tube breakage, loss of equipment effect and material loss.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a shell detection device, comprising:

[0006] It is composed of base, driving assembly, positioning assembly and measuring assembly;

[0007] The base is provided with components such as a driving component, a positioning component and a measuring component;

[0008] The driving assembly includes a rotating crank, a transmission structure and a driving pin, and is connected to and drives the positioning assembly through the transmission structure;

[0009] The measuring component includes a vertical pole, a movable cantilever and a dial indicator, and the dial indicator is arranged above the positioning component.

[0010] Preferably, the rotating crank is connected to the transmission structure, and the transmission structure is further connected to the detection positioning pin, so that the rotating crank is rotated to transmit the detection positioning pin, so that the detection positioning pin rotates around its own longitudinal center axis.

[0011] Preferably, the transmission structure is one of gear, belt and chain transmission.

[0012] Preferably, the detection positioning pin is provided on the detection positioning seat, and the detection positioning pin is inserted into the tube hole of the shell to be detected to achieve the positioning effect on the shell.

[0013] Preferably, a driving groove is further provided on the side of the detection positioning pin, and the driving pin is inserted into the oil inlet and the driving groove on the side of the shell in sequence.

[0014] Preferably, a level ruler is further included, which is arranged on the base to measure the levelness of the base.

[0015] The utility model provides a shell detection device and detection method, which have the following beneficial effects:

[0016] The shell detection device has a simple structure and is easy to operate. It effectively solves the problem that existing CNC machine tools penetrate and punch the shell, but have no actual detection means to ensure the concentricity of the tube holes at both ends, resulting in inconsistent concentricity at both ends, causing the membrane tube seal inside the shell to fail or the membrane tube to break, losing the equipment effect and causing material loss.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4 The present invention provides a technical solution: a shell detection device, comprising:

[0024] The base 1 is composed of components such as a level ruler 7, a drive component, a positioning component and a measuring component; the level ruler 7, the drive component, the positioning component and the measuring component are all arranged on the base 1, and the base supports the operation of the drive component, the positioning component and the measuring component; the level ruler 7 is arranged on the base 1 to measure the levelness of the base 1.

[0025] The positioning assembly includes a detection positioning seat 4 and a detection positioning pin 5. The detection positioning pin is arranged on the detection positioning seat 4, and the detection positioning seat provides support for the shell; the detection positioning pin 5 is inserted into the tube hole of the shell to be detected to position the shell. The positioning assembly is used to position the shell to be detected.

[0026] The driving assembly includes a rotating crank 3, a transmission structure 2 and a driving pin 6. The rotating crank provides power for the rotation of the shell. The transmission structure 2 can adopt one of gear transmission, belt transmission and chain transmission, and is connected and driven by the transmission structure 2 to connect and drive the positioning assembly, so that the detection positioning pin 5 rotates about its own longitudinal center axis. The driving pin 6 is inserted into the oil inlet 11 of the shell and falls into the driving groove at the upper end of the detection positioning pin 5, thereby driving the shell to slowly rotate about the longitudinal center axis of the driving pin 6.

[0027] The measuring assembly includes a vertical pole 8, a movable cantilever 9 and a dial indicator 10; the vertical pole 8 is vertically arranged on the base 1, and the other end of the base 1 is connected to the movable cantilever 9, the movable cantilever 9 is connected to the other end of the vertical pole 8 and then connected to the dial indicator 10, and the dial indicator 10 is set above the end face of the shell tube hole positioned on the detection positioning pin 5, and the position of the dial indicator probe for measurement is adjusted according to the measurement requirements.

[0028] The operating principle of this utility model is as follows:

[0029] By adjusting the detection position of the dial indicator 10, different detection requirements can be met.

[0030] First, place the detection device on the platform and check the spirit level 7 on the base 1 to ensure that the detection device remains level; then insert the shell tube hole 13 into the detection positioning pin 5 to detect whether the plane of one end of the shell is in contact with the detection positioning seat 4; secondly, insert the drive pin 6 into the oil inlet 11 and the drive groove of the shell; finally, according to the detection requirements, place the dial indicator 10 probe in the corresponding position, manually rotate the drive crank, and through the transmission parts, make the shell to be measured slowly rotate around the longitudinal center axis of the detection positioning pin 5, and record the error value of the dial indicator 10 to see if it is within the qualified range. For example, when checking the concentricity of the pipe hole, the dial indicator probe needs to be placed on the inner wall side of the O-ring groove 14. If the upper and lower pipe holes are concentric, the dial indicator 10 will not fluctuate much; if they are not on the same axis, the rotational motion trajectories of the upper hole and the lower hole are different, and the dial indicator 10 will fluctuate greatly; when checking the flatness of the gland end face 12 and the O-ring groove 14, the dial indicator probe can be directly placed on the horizontal surfaces of the gland end face 12 and the O-ring groove 14 respectively, and the fluctuation of the dial indicator 10 can be observed and recorded.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
