Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a component inner hole detector. Background Art

[0002] The component inner hole detector is a precision instrument used to measure and detect the size and defects of the inner holes of mechanical components. It can quickly and accurately detect the size, shape and internal defects of the inner hole, thereby ensuring product quality control and providing theoretical data basis for production parameter optimization.

[0003] Existing component bore detectors typically use gas-electricity meters for bore testing, utilizing the principle of air pressure for measurement. These instruments offer advantages such as high speed and accuracy. They utilize the pressure differential generated when compressed gas passes through a specific pipe or channel to determine gas flow or pressure parameters. This gas signal is then converted into an electrical signal via a gas-to-electricity converter.

[0004] However, when using existing detectors to inspect the inner holes of parts, workers are still required to place the parts in the inspection position. Because it is an inner hole inspection, workers need to adjust the coaxial precision by themselves when manually placing the parts to ensure that the parts to be inspected can be inserted into the inspection position. They can also manually rotate the parts to ensure complete inspection of the inner holes of the parts. The entire inspection process requires manual control, and the inspection efficiency is also low. When conducting assembly line inspection of a large number of parts, it is difficult to conduct rapid inspections in line with production. Utility Model Content

[0031] Example

[0032] Please refer to Figures 1-6 The utility model provides a component inner hole detector, including a detection platform 1, a gas volume measuring head 2, a gas volume display 3, an air pipe 4, a rotating component 5, a lifting structure 6, and a guide head 7.

[0033] In the prior art, a gas-volume meter is usually used to detect the inner holes of components. The gas-volume meter is generally configured by setting up a detection platform 1 on which the components are placed. A gas volume measuring head 2 is provided on the detection platform 1 and extends into the inner hole of the component to be detected. The gas volume measuring head 2 is connected to the gas volume display 3 through the gas volume channel 202.

[0034] Among them, the gas volume display instrument 3 is provided with a voltage stabilizer for stabilizing the compressed gas, a gas pressure gauge for measuring the air pressure, and an air pressure index display pointer. When performing internal hole detection on components, compressed gas is introduced into the gas volume measuring head 2, and air pressure is ejected to the internal hole of the component outside the gas volume measuring head 2. Due to different aperture error ranges, the air pressure to which the compressed gas is subjected after being ejected is also different. Therefore, the change in air pressure during the flow of gas is utilized to convert the gas signal into an observable index signal through the gas pressure gauge and the air pressure index display pointer.

[0035] In this embodiment, in order to increase the detection efficiency, a lifting structure 6 is added to automatically clamp the parts and transport them to the inner hole detection position; by adding a rotating component 5, the gas flow measuring head 2 is driven to select and automatically perform circularity detection on the entire inner hole of the part.

[0036] Furthermore, the gas volume measuring head 2 is rotatably connected to the detection platform 1 . The gas volume measuring head 2 is mounted on the rotating end of the rotating assembly 5 , and the rotating assembly 5 is fixed on the detection platform 1 .

[0037] Preferably, when the component is placed on the gas flow measuring head 2 of the detection platform 1, the gas flow measuring head 2 blows air to detect the inner hole, but the air blowing port of the gas flow measuring head 2 is in a fixed position, so the component needs to be rotated at least one circle before the gas flow measuring head 2 can completely detect the inner hole of the component. Therefore, a rotating component 5 is provided to drive the gas flow measuring head 2 to rotate. While keeping the component stationary on the detection platform 1, the inner hole of the component is automatically fully detected, and the manual rotation of the component is no longer used, thereby improving the detection efficiency.

[0038] Furthermore, a lifting structure 6 is provided on the detection platform 1, and the lifting structure 6 includes a lifting component and a clamping component. The lifting component is provided on the detection platform 1, and a clamping component is provided on the lifting end of the lifting component; wherein, the clamping position of the clamping component corresponds vertically to the detection position of the gas volume measuring head 2.

[0039] A guide head 7 is also fixedly provided on the top of the gas flow measuring head 2 .

[0040] In the prior art, when manually placing components into the gas flow measuring head 2, since the outer diameter of the gas flow measuring head 2 is a standard aperture, and the inner aperture of the component is an aperture with an error range, the gap between the two hole positions and the wall surface is very small. During the manual placement process, the component may be difficult to place into the gas flow measuring head 2 or directly stuck on the gas flow measuring head 2 due to tilted placement.

[0041] Preferably, the parts are placed manually in the clamping assembly, and the inner hole of the parts is put on the guide head 7. The parts are clamped and fixed by the clamping assembly, and then moved up and down by the lifting assembly. The inner hole of the parts is gradually moved down to the outer diameter position of the gas measuring head 2 through the guidance of the guide head 7 to achieve coaxial vertical displacement. The automatic and precise displacement of the mechanical structure is used to achieve horizontal placement of the parts.

[0042] In addition, when the gas flow measuring head 2 performs inner hole detection on a component, the clamping assembly will clamp and fix the component, thereby ensuring that the component is fixed when the gas flow measuring head 2 rotates for detection.

[0043] Please refer to Figure 3 and Figure 4 In this embodiment, the gas flow measuring head 2 includes an inner diameter head 201 , a gas flow channel 202 , and a connecting ring 203 .

[0044] Specifically, the inner diameter head 201 is vertically fixedly installed on the detection plane of the detection platform 1, and the outer wall diameter of the inner diameter head 201 is the standard aperture of the component to be detected.

[0045] A plurality of gas flow channels 202 are provided inside the inner diameter head 201. The openings of the plurality of gas flow channels 202 pass through the outer wall of the inner diameter head 201 to detect multiple positions of the inner hole of the component. The openings are arranged up and down, and different heights of the inner hole of the component can be detected. It can be suitable for stepped inner holes with different apertures. The plurality of gas flow channels 202 are connected to the main pipe of the inner diameter head 201. The main pipe passes through the bottom surface of the inner diameter head 201. The main pipe is connected to the air pipe 4, which is responsible for introducing compressed gas into each gas flow channel 202.

[0046] Among them, a connecting ring 203 is rotatably provided on the inner wall of the main pipe near the bottom surface of the inner diameter head 201, and the connecting ring 203 is also rotatably connected to the air pipe 4 connected to the main pipe at this location. The main pipe, the air pipe 4 and the inner diameter head 201 are coaxially arranged, thereby ensuring that the gas flow measuring head 2 will not cause the rotation of the air pipe 4 to which it is connected under the drive of the rotating component 5, thereby avoiding entanglement and interference of the air pipe 4.

[0047] Please refer to Figure 3 、 Figure 5 and Figure 6 In this embodiment, the rotating assembly 5 includes a gear ring 501 , a gear 502 , and a first motor 503 .

[0048] Specifically, a gear ring 501 is coaxially fixed to the bottom surface of the bore head 201 and meshes with a gear 502. The gear 502 is rotatably mounted on the bottom of the detection platform 1. The gear 502 is coaxially fixed to the drive shaft of a first motor 503, which is also fixed to the bottom of the detection platform 1. When the first motor 503 is in operation, it drives the bore head 201 to rotate through the gear ring 501 meshing with the gear 502, thereby achieving automatic rotation detection of the gas flow measuring head 2.

[0049] Please refer to Figure 3 and Figure 4 In this embodiment, the lifting assembly includes a slot plate 601, a screw 602, a second motor 603, a slide 604

[0050] Specifically, a slot plate 601 is fixedly mounted on one side of the inspection platform 1. A screw 602 is vertically rotatably disposed within the slot of the slot plate 601. One end of the screw 602 is fixedly connected to the drive shaft of the second motor 603. A slide 604 is threadedly matched with the screw 602. The slide 604 slides vertically within the slot of the slot plate 601. When the second motor 603 is operating, the slide 604 moves up and down within the slot plate 601, thereby driving the vertical movement of the clamping assembly.

[0051] The clamping assembly includes a clamping cylinder 605 and a clamping plate 606.

[0052] Specifically, the clamping cylinder 605 is fixedly mounted on the slide 604 , a clamping plate 606 is fixedly mounted on the clamping claw of the clamping cylinder 605 , and a supporting plate is horizontally fixed on the clamping plate 606 .

[0053] The two clamping jaws (forming a clamping structure) disposed opposite to each other on the clamping jaw cylinder 605 also correspond to the two clamping plates 606 and the supporting plate disposed opposite to each other.

[0054] The support plate is located directly above the inner diameter head 201 and has a circular groove on the support plate to avoid the gas flow measuring head 2, so as to avoid interference with the gas flow measuring head 2 when the support plate lifts the parts and moves up and down.

[0055] When the component to be inspected is manually placed on the pallet, the clamping cylinder 605 drives the clamping plate 606 to clamp the component to the center of the gas flow measuring head 2, and then through the guide head 7 arranged in the inner hole of the component, when the component is clamped and moved down, the placement margin error generated in the direction perpendicular to the clamping direction is slowly offset by the guide displacement of the component using the guide head 7, thereby achieving the action of precise placement on the gas flow measuring head 2.

[0056] Among them, the upper end diameter of the guide head 7 is smaller than the diameter of the inner diameter head 201 in the gas flow measuring head 2, and the lower end diameter of the guide head 7 is consistent with the diameter of the inner diameter head 201 in the gas flow measuring head 2, ensuring the guiding function of the guide head 7.

Based on the above description, those skilled in the art will fully understand how to implement the technical solutions of the present invention.
