Description

Technical Field

[0001] This invention relates to the field of sealing detection technology, and in particular to a sealing detection device for the spindle box of a needle punching machine. Background Technology

[0002] Currently, in the sealing test of the spindle box of the acupuncture machine, most of the manual methods are to seal the shaft holes, oil level holes, oil drain holes and vent holes at both ends of the spindle box one by one, and then connect an external air inflation device to carry out pressure holding and leak detection. The overall process is relatively scattered and cannot achieve simultaneous sealing and air inflation testing, resulting in poor work continuity.

[0003] Manually sealing the gas one by one is not only cumbersome and labor-intensive, but also inefficient. Furthermore, it is difficult to uniformly apply the sealing force, which can easily lead to problems such as incomplete sealing or misalignment of the seals, resulting in gas leaks and causing deviations in the detection data, making it difficult to guarantee the accuracy of the detection.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the further embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] like Figures 1-2 As shown, a sealing detection device for the spindle box of an acupuncture machine includes: a base plate 1, guide posts 8 symmetrically arranged on both sides of the base plate 1, a placement platform 9 slidably connected to the outer surface of the guide posts 8, a handle 10 fixedly connected to the outer surface of the placement platform 9, a side groove 7 opened on the side of the base plate 1 corresponding to the handle 10, a support frame 2 fixedly connected to the top of the base plate 1, a top plate 3 fixedly connected to the top of the support frame 2, and a first motor 4 fixedly connected to the top of the top plate 3. Also includes: The positioning unit 5 is installed at the output end of the first motor 4, and the detection unit 6 is installed at the bottom of the top plate 3; In operation, the acupuncture machine spindle box is first placed on the placement platform 9. Then, the placement platform 9 containing the acupuncture machine spindle box is dragged by the handle 10 to move below the top plate 3. The detection unit 6 first positions the hole of the acupuncture machine spindle box. Then, the positioning unit 5 drives the detection unit 6 to seal the hole of the acupuncture machine spindle box and perform a sealing test on the entire acupuncture machine spindle box.

[0034] like Figures 3-4 As shown, the detection unit 6 includes a first support rod 61, a track plate 62 fixedly connected to the bottom of the first support rod 61, a sliding groove 63 provided on the track plate 62, an guide plate 64 fixedly connected to the outer surface of the track plate 62, a bearing block 65 placed on the guide plate 64, a top insertion hole 613 provided on the top of the bearing block 65, a side insertion hole 614 provided on the outer surface of the bearing block 65, a detection assembly 66 inserted into the bearing block 65, a first support column 67 fixedly connected to the bottom of the track plate 62, a first frame plate 68 fixedly connected to the bottom of the first support column 67, four vision sensors 69 evenly arranged on the bottom of the first frame plate 68, and the vision sensors 69 arranged on the bottom of the first frame plate 68 collect data on the positions of each hole in the spindle box of the acupuncture machine in real time. The image is used to accurately identify and locate the hole position. Then, the positioning unit 5 cooperates with the grasping and transferring detection assembly 66 to accurately transport it to the shaft holes, oil level holes, oil drain holes, and vent holes at both ends of the spindle box of the needle punch machine. The outer surface of the guide plate 64 is fixedly connected to the first support plate 610, and the outer surface of the first support plate 610 is fixedly connected to the first telescopic rod 611. The output end of the first telescopic rod 611 is fixedly connected to the push plate 612. The first telescopic rod 611 extends and drives the push plate 612 to push the carrier block 65, so that it slides along the guide plate 64 and enters the sliding groove 63. Then, the detection assembly 66 is inserted and assembled on the carrier block 65, and the top insertion hole 613 and the side insertion hole 614 of the carrier block 65 are used to complete the alignment and limit. The testing assembly 66 sequentially performs pre-treatment cleaning of the holes, then seals and plugs various holes, and finally completes the airtightness test of the overall cavity of the needle punch machine spindle box.

[0035] By inserting and fixing the detection assembly 66 onto the bearing block 65, and then moving the detection assembly 66 to each hole position of the spindle box of the acupuncture machine via the positioning unit 5, the detection assembly 66 is used to complete the pretreatment and sealing airtightness test of the shaft holes, oil level holes, oil drain holes and vent holes at both ends of the spindle box of the acupuncture machine.

[0036] like Figure 14As shown, the positioning unit 5 includes a rotating arm 51, one end of which is fixedly connected to a second support plate 52. A third support column 53 is fixedly connected to the outer surface of the second support plate 52. A third sliding block 54 is slidably connected to the outer surface of the third support column 53. A second telescopic spring 55 is fixedly connected to the outer surface of the third sliding block 54. One end of the second telescopic spring 55 away from the third sliding block 54 is fixedly connected to the outer surface of the second support plate 52. A fourth telescopic rod 56 is fixedly connected to the bottom of the third sliding block 54. A second insertion post 57 is fixedly connected to the output end of the fourth telescopic rod 56.

[0037] The top of the rotating arm 51 is fixedly connected to the output end of the first motor 4, and the second insertion post 57 is adapted to the side insertion hole 614.

[0038] When it is necessary to dock the test assembly 66, the fourth telescopic rod 56 extends and drives the second insertion post 57 to move down, so that the second insertion post 57 is accurately inserted into the side insertion hole 614 of the support block 65, completing the quick insertion and locking with the support block 65 and the test assembly 66 above. After locking, the first motor 4 will drive the rotating arm 51 and the locked test assembly 66 to move to the specific hole position. After cooperating with the test assembly 66 to complete the cleaning and sealing work, the fourth telescopic rod 56 is retracted and drives the subsequent movement of other test assemblies 66.

[0039] like Figures 5-6 As shown, the detection assembly 66 includes a top block 661. A first insertion post 662 is fixedly connected to the outer surface of the top block 661. The detection assembly 66 is inserted into the top insertion hole 613 on the top of the support block 65 through the first insertion post 662 on the outer side of the top block 661, completing its positioning and assembly on the support block 65. It then completes the station transfer together with the support block 65. A second frame plate 663 is fixedly connected to the bottom of the top block 661. A second motor 664 is fixedly connected to the outer surface of the second frame plate 663. The output end of the second motor 664... A ball screw is fixedly connected, and a movable platform 667 is threadedly connected to the outer surface of the ball screw. A guide rod 666 is fixedly connected inside the second frame plate 663. The movable platform 667 is slidably sleeved on the outer surface of the guide rod 666. A cleaning mechanism 668 and a sealing mechanism 669 are respectively provided on the outer surface of the movable platform 667. The cleaning mechanism 668 and the sealing mechanism 669 work together. A pressurizer 6610 is also fixedly connected to the outer surface of the movable platform 667. The pressurizer 6610 is connected to the sealing mechanism 669 through an air pipe. When the positioning unit 5 moves the detection assembly 66 to the side of the hole to be tested in the spindle box of the needle punching machine, the second motor 664 drives the ball screw to rotate, which drives the moving platform 667 to slide smoothly along the guide rod 666, thereby moving the cleaning mechanism 668 and the sealing mechanism 669 to the same horizontal plane as the hole.

[0040] The top of the first support rod 61 is fixedly connected to the outer surface of the top plate 3. The top block 661 can slide along the guide plate 64 and the sliding groove 63. The first insertion post 662 is adapted to the top insertion hole 613.

[0041] like Figures 7-8 As shown, the cleaning mechanism 668 includes a third motor 6681. The output end of the third motor 6681 is fixedly connected to a rotating shaft 6682. One end of the rotating shaft 6682 is fixedly connected to a second telescopic rod 6683. The output end of the second telescopic rod 6683 is fixedly connected to a sludge storage tank 6685. A disassembly plate 6686 is provided at the bottom of the sludge storage tank 6685. A negative pressure machine 6687 is fixedly connected to the outer surface of the sludge storage tank 6685. The negative pressure machine 6687 is connected to the inside of the sludge storage tank 6685 through a connecting pipe 66811 to achieve negative pressure suction inside the sludge storage tank 6685. A fitting mechanism 6688 is provided at the top of the sludge storage tank 6685. A collection mechanism 6689 is also provided on the fitting mechanism 6688. The fitting mechanism 6688 is used to drive the collection mechanism 6689 to always fit against the end face of the hole of the needle punch machine spindle box. A collection hose 66810 is fixedly connected to the top of the sludge storage tank 6685.

[0042] First, the second telescopic rod 6683 will move the sludge storage tank 6685 and the connected bonding mechanism 6688, collection mechanism 6689, negative pressure machine 6687 and other components to a position flush with the test hole in the main shaft box. Then, the third motor 6681 will start, driving the rotating shaft 6682 to rotate, which will drive the sludge storage tank 6685 and the bonding mechanism 6688 and collection mechanism 6689 below to rotate synchronously. During this process, the centrifugal force generated by the rotation will cause the bonding mechanism 6688 to work and make the collection mechanism 6689 completely fit with the hole. The collection mechanism 6689 will collect the fiber shavings on the hole.

[0043] like Figure 9 As shown, the bonding mechanism 6688 includes a second support column 66881, a dome 66883 fixedly connected to the top of the second support column 66881, a first telescopic spring 66882 fixedly connected to the bottom of the dome 66883, a first sliding plate 66884 fixedly connected to the bottom of the first telescopic spring 66882, a conductive hollow tube 66886 fixedly connected to the top surface of the first sliding plate 66884, the conductive hollow tube 66886 passing through the inside and outside of the first sliding plate 66884, and a spade 66885 fixedly connected to the top of the dome 66883.

[0044] The top surface of the first sliding plate 66884 is fixedly connected to the conductive hollow tube 66886, which smoothly conducts the debris scraped off by the collection mechanism 6689 to the collection hose 66810, and then is sucked into the sludge storage tank 6685 by negative pressure, thus realizing the smooth conduction of debris collection.

[0045] As the third motor 6681 drives the bonding mechanism 6688 to rotate, the centrifugal force generated by the rotation causes the first sliding plate 66884 to move along the second support column 66881, thereby driving the conductive hollow tube 66886 and the collection mechanism 6689 to fully fit with the hole.

[0046] The base of the third motor 6681 is fixedly installed on the outside of the mobile platform 667. The bottom end of the second support column 66881 is fixedly connected to the top surface of the sludge storage tank 6685. The top surface of the first sliding plate 66884 is connected to one end of the collection hose 66810.

[0047] like Figures 10-11 As shown, the collecting mechanism 6689 includes an L-shaped scraper 66891, with its side end face designated as an outer wall pushing surface 66892. An inner scraper 66893 is symmetrically fixed to the outer side of the L-shaped scraper 66891, and a magnetic block is added inside the inner scraper 66893. A rotating column 66895 is symmetrically and rotatably mounted on the inner wall of the L-shaped scraper 66891. A roller 66894 is fixedly connected to one end of the rotating column 66895. Support bars 66896 are evenly fixed to the outer circumference of the rotating column 66895. A rotating knuckle column 66897 is rotatably mounted on the support bar 66896. A magnetic block that attracts the magnetic block inside the inner scraper 66893 is added inside the rotating knuckle column 66897. A first abutment is also fixedly connected to the support bar 66896. The first baffle 66898 has a second baffle 66899 fixedly connected to its outer side. The first baffle 66898 and the second baffle 66899 serve to limit the rotation of the rotating knuckle column 66897 and each knuckle assembly, ensuring stable linkage under the action of magnetic force and centrifugal force. The first baffle 66898 will block the rotating knuckle column 66897 from rotating in the opposite direction, while the second baffle 66899 will limit the rotation angle of the rotating knuckle column 66897. The second knuckle assembly 668910 is equipped at the end of the rotating knuckle column 66897 away from the support bar 66896, and the third knuckle assembly 668911 is equipped at the end of the second knuckle assembly 668910 away from the rotating knuckle column 66897.

[0048] As the collecting mechanism 6689 rotates around the hole, the outer wall push surface 66892 continuously scrapes away impurities such as fiber shavings and dust adhering to the outer end of the hole. Simultaneously, the inner scraper 66893 scrapes and carries the fiber shavings from the axial inner groove end face of the hole, achieving simultaneous cleaning of debris inside and outside the hole. However, as the collected shavings accumulate, the scraper cleaning becomes obstructed, reducing the debris cleaning efficiency. The roller 66894 at one end of the L-shaped scraper's inner wall rotating column 66895 rolls into contact with the axial end face of the hole, driving the rotating column 66895 under friction. The 895 rotates synchronously, thereby driving the support bars 66896, which are uniformly fixed on the outer periphery of the rotating column 66895, as well as the rotating knuckle column 66897, the second knuckle assembly 668910, and the third knuckle assembly 668911 mounted on the support bars 66896, to rotate together. Because a magnetic block is added inside the inner scraper 66893, and a magnetic block that attracts the magnetic block is added inside the rotating knuckle column 66897, when the rotating knuckle column 66897, the second knuckle assembly 668910, and the third knuckle assembly 668911 rotate to the outer side... When (near the inner scraper 66893), under the magnetic attraction, the three components rotate and form a hook shape. The hook-shaped structure precisely fits the surface of the inner scraper 66893, firmly hooking the fiber scraps carried on the inner scraper 66893. As the rotating column 66895 continues to rotate, when the three components rotate into the interior of the L-shaped scraper (away from the inner scraper 66893, in the area where the magnetic force disappears), the centrifugal force generated during the rotation overcomes the self-weight of each finger joint component, causing the originally hook-shaped rotating finger joint column 66897 and the second... The knuckle assembly 668910 and the third knuckle assembly 668911 automatically extend into a straight shape. At this time, the hooked fiber shavings are detached from the knuckle assembly under the action of centrifugal force and fall into the L-shaped scraper. At the same time, the negative pressure machine 6687 in the sludge storage tank 6685 continues to work, generating a stable negative pressure. Through the conduction hollow tube 66886 on the first sliding plate 66884 and the collection hose 66810, a negative pressure suction channel is formed, which smoothly sucks the fiber shavings and impurities inside the L-shaped scraper into the sludge storage tank 6685, completing the collection of debris.

[0049] The bottom of the L-shaped scraper 66891 is fixedly connected to the top of the conductive hollow tube 66886. The composition and connection relationship of the second finger assembly 668910 and the third finger assembly 668911 are consistent with the combined structure formed by the rotating finger column 66897, the first baffle plate 66898, and the second baffle plate 66899.

[0050] like Figures 12-13As shown, the sealing mechanism 669 includes a third telescopic rod 6691, a sealing disc 6692 is detachably installed at the output end of the third telescopic rod 6691, a sealing ring is fixedly fitted on the outer ring of the sealing disc 6692, the inner ring of the sealing disc 6692 is adapted to various detection hole diameters of the spindle box, an air inlet 6693 is provided on the outer side of the sealing disc 6692, and a pressure sensor 6694 is embedded inside the sealing disc 6692.

[0051] The base of the third telescopic rod 6691 is fixedly installed on the outside of the mobile platform 667, and the inflation interface 6693 is connected to the pressurizer 6610 through an air pipe.

[0052] The sealing mechanism 669 moves synchronously with the moving platform 667. After the cleaning mechanism 668 completes the hole pretreatment, the positioning unit 5 controls the sealing disc 6692 to align with the hole. Then, the third telescopic rod 6691 pushes the detachable sealing disc 6692 to fit against the hole to be tested in the spindle box, forming a sealed structure through the sealing ring. The pressurizer 6610 introduces low-pressure test gas into the spindle box through the air inlet 6693. The air pressure sensor 6694 embedded in the sealing disc 6692 monitors the air pressure change in the cavity in real time, completing the hole sealing and airtightness test. After the test is completed, the third telescopic rod 6691 drives the sealing disc 6692 to reset, and the sealing disc 6692 can be replaced according to different hole diameters.

[0053] It should be noted that all first telescopic poles 611, second telescopic poles 6683, third telescopic poles 6691, and fourth telescopic poles 56 have built-in backup power supplies 6684, which can independently power their own power to achieve stable telescopic movements without the need for external wiring, thus improving the operational flexibility of the equipment. The working principle of this invention is as follows: First, the spindle box of the needle punching machine is placed on the placement platform 9 and moved below the top plate 3. The vision sensor 69 completes the precise positioning of each hole. The first motor 4 drives the rotating arm 51 of the positioning unit 5 to rotate. The fourth telescopic rod 56 drives the second insertion post 57 to insert and lock the detection assembly 66 on the carrier block 65. Then, the detection assembly 66 is moved to the hole to be tested. The detection assembly 66 is positioned and limited by the first insertion post 662 and the carrier block 65. The second motor 664 drives the ball screw to move the moving platform 667 to switch positions. First, the second telescopic rod 6683 sends the cleaning mechanism 668 to the position flush with the hole. The third motor 6681 drives the collecting mechanism 6689 to rotate and operate with the help of centrifugal force. The bonding mechanism 6688 achieves adaptive bonding by relying on the first telescopic spring 66882. The L-shaped scraper cleans the fly debris and impurities in the holes simultaneously on the inner and outer sides. The roller 66894 rotates and drives each finger component to bend into a hook shape using magnetic force to pick up the debris. After leaving the magnetic area, the debris is unloaded under the action of centrifugal force. Then, the negative pressure machine 6687 collects the debris into the waste storage tank 6685 through the pipeline. After the hole cleaning is completed, the machine switches to the sealing mechanism 669. The third telescopic rod 6691 pushes the sealing disc 6692 to block the hole. A sealed space is formed by the sealing ring. The pressurizer 6610 introduces the detection gas and works with the air pressure sensor 6694 to monitor the air pressure change. This completes the overall airtightness test of the needle punch machine spindle box.
