Description

Technical Field

[0001] This utility model belongs to the field of testing technology, specifically relating to a cover assembly testing mechanism. Background Technology

[0002] Cover parts generally refer to cap-like parts, which are widely used in machinery, mold making, and other fields. Examples include valve covers on valve bodies, cover plates for punch press parts, and box covers, which serve functions such as protection, sealing, and support. They are made of various materials, such as plastics and metals, and the appropriate material must be selected according to the specific application scenario, while also meeting requirements such as wear resistance, corrosion resistance, and high surface quality.

[0003] Cover assembly inspection agencies are professional technical organizations that conduct assembly inspections of cover-type parts. They utilize instruments, equipment, environmental facilities, and other technical conditions and professional skills to conduct comprehensive inspections of the assembly quality of cover parts in accordance with relevant standards or technical specifications.

[0004] In existing cover assembly and testing mechanisms, bolt connection is a common method for connecting the sensor and the testing mechanism. Specifically, the sensor is securely installed in the designated position of the testing mechanism using matching bolts and nuts through pre-designed mounting holes on the sensor and the testing mechanism. This connection method ensures that the sensor remains stable during the testing process and is not prone to loosening or displacement, thereby guaranteeing the accuracy and reliability of the measurement.

[0005] While connecting the detection sensor with bolts can ensure its stability, in actual use, installing and removing the sensor often requires the use of tools such as screwdrivers, which consumes a lot of time and results in low work efficiency. Utility Model Content

[0006] The purpose of this invention is to solve the problem of low work efficiency when installing and removing detection sensors in the prior art, and to provide a cover assembly detection mechanism.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A cover assembly inspection mechanism includes a base frame, a support frame mounted on one side of the base frame, a mounting plate connected below the support frame, a fixing plate connected above the mounting plate, and a component to be inspected positioned below the mounting plate. The mounting plate and fixing plate each have four through holes corresponding to the component to be inspected. A height sensor is installed in each of the four through holes. A power connector is electrically connected to the upper end of the height sensor, and a detection sensor head is connected to the lower end of the height sensor. A clamping housing is located in the middle of the outer side of the height sensor. A set of first, second, third, and fourth inserts are respectively connected to the lower outer sides of the four clamping housings. A first slot, second slot, third slot, and fourth slot are respectively provided above the fixing plate corresponding to the positions of the first, second, third, and fourth inserts. A first groove, second groove, third groove, and fourth groove are respectively provided below the fixing plate corresponding to the positions of the first, second, third, and fourth inserts.

[0009] Preferably, a mounting connector is fitted onto the outside of the height sensor at a position corresponding to the clamping housing, and the mounting connector is fitted inside the clamping housing.

[0010] Preferably, each group of first, second, third and fourth insert blocks is arranged in a circumferential array of three blocks, and the sizes of the three first, second, third and fourth insert blocks are all different.

[0011] Preferably, sleeves are connected to the positions of the first, second, third, and fourth insert blocks inside the mounting plate, and sliders are slidably connected inside the sleeves, with semi-circular locking blocks connected above the sliders.

[0012] Preferably, a semi-circular locking block is connected above the slider, and positioning grooves are opened below the first, second, third, and fourth insert blocks at the positions corresponding to the semi-circular locking blocks. The semi-circular locking blocks are located in the positioning grooves, and a spring is connected between the slider and the sleeve.

[0013] Preferably, a number mark is provided on the outer side of the clamping housing at a position corresponding to the position above the fixing plate, and an auxiliary mark is provided on the upper surface of the fixing plate at a position corresponding to the number mark.

[0014] Preferably, the base frame is connected to symmetrically arranged slide rails on the side near the support frame, the support frame is slidably connected to the slide rails, and a cylinder is connected above the base frame, with the cylinder output end connected to the support frame.

[0015] Preferably, a reference probe is connected to the mounting plate at the position corresponding to the part to be tested, and multiple detection sensors are set on the support frame at the position corresponding to the part to be tested.

[0016] The beneficial effects of this utility model are:

[0017] Based on the numerical and auxiliary markings, place the corresponding height sensor into the corresponding through hole, and then place the first, second, third, and fourth inserts into the first, second, third, and fourth slots respectively. Since the dimensions of the three inserts are different, incorrect placement can be avoided. After placement, rotate the clamping housing, causing each insert to rotate and engage with its corresponding slot. During insertion, each insert contacts the semi-circular locking block, compressing it and pushing it into the sleeve, thus compressing the slider. The slider slides within the sleeve and compresses the spring. The spring contracts and stores its restoring force. After the first, second, third, and fourth inserts are fully inserted into their respective slots, the semi-circular block aligns with the positioning groove. Under the spring's restoring force, the slider and semi-circular block reset, allowing the semi-circular block to enter the positioning groove, further securing the height sensor and preventing displacement. To remove the height sensor, rotate the clamping housing in the opposite direction, causing the first, second, third, and fourth inserts to move out of their respective slots, thus dislodging the height sensor. The first, second, third, and fourth inserts can then be removed from their slots, completing the removal process. This method is convenient for installing and removing height sensors and improves work efficiency. Attached Figure Description

[0033] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0034] Please see Figure 1 - Figure 9 As shown, a cover assembly and inspection mechanism includes a base frame 1, and a support frame 11 is provided on the upper side of one side of the base frame 1. The support frame 11 is used to connect the mounting plate 2 and support and fix the mounting plate 2.

[0035] The base frame 1 is connected to a symmetrically arranged slide rail 12 on the side near the support frame 11. The support frame 11 is slidably connected to the slide rail 12. The slide rail 12 is used to limit the movement position of the support frame 11, so that the support frame 11 can only be raised and lowered.

[0036] A cylinder 13 is connected above the base frame 1. The output end of the cylinder 13 is connected to the support frame 11. The cylinder 13 is used to drive the support frame 11 to lift and lower.

[0037] A mounting plate 2 is connected to the bottom of the support frame 11, a fixing plate 21 is connected to the top of the mounting plate 2, and a test piece 6 is set below the mounting plate 2. The mounting plate 2 and the fixing plate 21 cooperate to fix the position of the height sensor 22.

[0038] The mounting plate 2 is connected to the reference probe 25 at the position corresponding to the part 6 to be tested. The reference probe 25 is used to provide a stable reference for measurement, ensure detection accuracy and consistency, and capture minute errors.

[0039] The mounting plate 2 and the fixing plate 21 each have four through holes 4 at the positions corresponding to the parts to be tested 6. The through holes 4 are used to allow the height sensor 22 to pass through.

[0040] Each of the four through holes 4 is equipped with a height sensor 22. The upper end of the height sensor 22 is electrically connected to a power connector 23, and the lower end of the height sensor 22 is connected to a detection sensor head 24. The power connector 23 is used to supply power to the height sensor 22. The height sensor 22, together with the detection sensor head 24, can detect the workpiece 6 to be tested. The four height sensors 22 are used to determine whether the workpiece 6 to be tested is qualified.

[0041] A clamping housing 3 is provided on the middle of the outer side of the height sensor 22. The clamping housing 3 is used to connect the height sensor 22, so as to realize quick installation and removal of the height sensor 22.

[0042] An installation connector 5 is fitted onto the outside of the height sensor 22 at the position corresponding to the clamping housing 3, and the installation connector 5 is fitted into the clamping housing 3. Through the cooperation of the installation connector 5, the clamping housing 3 and the height sensor 22 are connected and fixed.

[0043] Each of the four clamping housings 3 has a set of first inserts 301, second inserts 302, third inserts 303 and fourth inserts 304 connected to its lower outer side. Each set of first inserts 301, second inserts 302, third inserts 303 and fourth inserts 304 is arranged in a circumferential array of three, and the three first inserts 301, second inserts 302, third inserts 303 and fourth inserts 304 are all different in size. This arrangement can prevent the height sensor 22 from being installed in the wrong position.

[0044] A number mark 7 is provided on the outer side of the clamping housing 3 at the position above the fixing plate 21. An auxiliary mark 71 is provided on the upper surface of the fixing plate 21 at the position corresponding to the number mark 7. By cooperating with the number mark 7 and the auxiliary mark 71, the installation position of the height sensor 22 can be further determined.

[0045] The upper part of the fixing plate 21, corresponding to the positions of the first insert block 301, the second insert block 302, the third insert block 303, and the fourth insert block 304, respectively, has a first slot 311, a second slot 312, a third slot 313, and a fourth slot 314. The lower part of the fixing plate 21, corresponding to the positions of the first insert block 301, the second insert block 302, the third insert block 303, and the fourth insert block 304, has a first slot 321, a second slot 322, a third slot 323, and a fourth slot 324. Through the first insert block... The cooperation of slot 311, second slot 312, third slot 313 and fourth slot 314 can initially determine the installation positions of first insert 301, second insert 302, third insert 303 and fourth insert 304. By rotating the clamping housing 3, and with the cooperation of first slot 321, second slot 322, third slot 323 and fourth slot 324, the first insert 301, second insert 302, third insert 303 and fourth insert 304 can be fixed.

[0046] Sleeves 33 are connected to the positions of the first insert 301, the second insert 302, the third insert 303 and the fourth insert 304 in the mounting plate 2. Sliding sliders 331 are slidably connected in the sleeves 33. The sleeves 33 are used to house the sliders 331 and the springs 333.

[0047] A semi-circular locking block 332 is connected above the slider 331. Positioning grooves 334 are provided below the first insertion block 301, the second insertion block 302, the third insertion block 303, and the fourth insertion block 304 corresponding to the position of the semi-circular locking block 332. The semi-circular locking block 332 is located in the positioning groove 334. The semi-circular locking block 332 cooperates with the positioning groove 334 to fix the position of the first insertion block 301, the second insertion block 302, the third insertion block 303, and the fourth insertion block 304, preventing the height sensor 22 from shifting.

[0048] A spring 333 is connected between slider 331 and sleeve 33. Spring 333 is used to reset slider 331 and semi-circular locking block 332.

[0049] The support frame 11 is equipped with multiple detection sensors 14 at the positions corresponding to the parts to be tested 6. The detection sensors 14 are used to detect whether the product cover meets the assembly requirements after assembly, GT detects the height, and IX detects that the buckle cannot break.

[0050] In practical use, according to the numerical mark 7 and auxiliary mark 71, the corresponding height sensor 22 is placed in the corresponding through hole 4, and the first insert 301, the second insert 302, the third insert 303, and the fourth insert 304 are placed in the first slot 311, the second slot 312, the third slot 313, and the fourth slot 314, respectively. Because the three first inserts 301, the second insert 302, the third insert 303, and the fourth insert 304 are all different in size, so that misplacement can be avoided when placing the first insert 301, the second insert 302, the third insert 303, and the fourth insert 304. After placement, the clamp is rotated respectively. Holding the outer shell 3, the clamping mechanism drives the first insertion block 301, the second insertion block 302, the third insertion block 303, and the fourth insertion block 304 to rotate, causing them to engage with the first slot 321, the second slot 322, the third slot 323, and the fourth slot 324 respectively. During insertion, the rotating first insertion block 301, the second insertion block 302, the third insertion block 303, and the fourth insertion block 304 all contact the semi-circular locking block 332 and compress it. The semi-circular locking block 332 is compressed into the sleeve 33, further compressing the slider 331. The slider 331 slides within the sleeve 33 and compresses the spring 333. The spring 333, under compression, contracts and stores restoring force. After the first insert 301, second insert 302, third insert 303, and fourth insert 304 are fully inserted into the first slot 321, second slot 322, third slot 323, and fourth slot 324, the semi-circular block 332 aligns with the positioning groove 334. Under the restoring force of the spring 333, the slider 331 and the semi-circular block 332 reset, causing the semi-circular block 332 to enter the positioning groove 334, thereby further securing the height sensor 22 and preventing it from shifting. When it is necessary to remove the height sensor 22, rotate the clamping housing 3 in the opposite direction to move the first insert 301, the second insert 302, the third insert 303, and the fourth insert 304 out of the first slot 321, the second slot 322, the third slot 323, and the fourth slot 324 respectively. This causes the height sensor 22 to lose its fixation. Then, remove the first insert 301, the second insert 302, the third insert 303, and the fourth insert 304 from the first slot 311, the second slot 312, the third slot 313, and the fourth slot 314 to complete the removal work. This method is convenient for installing and removing the height sensor 22 and can improve work efficiency.

[0051] Working principle:

[0052] Place the part to be tested 6 under the fixed plate 21. After placement, start the cylinder 13 to make the support frame 11 drive the height sensor 22 to descend. After the height sensor 22 descends, the detection sensor head 24 contacts the part to be tested 6. After the detection sensor head 24 contacts the part to be tested 6, it retracts to calculate the height. By using the four detection sensor heads 24 to detect four different positions of the part to be tested 6, the assembly can be judged as qualified based on the detection values, avoiding detection errors caused by detecting a single position.
