Description

Technical Field

[0001] This utility model relates to the field of nail testing technology, and in particular to a device for testing the overall sealing performance of continuous-fired nails. Background Technology

[0002] Rapid-fired nails are a common fastening tool widely used in construction, decoration, and manufacturing industries. The sealing performance of rapid-fired nails is one of their most important performance indicators. Poor sealing can lead to insufficient power during firing, jamming, and even safety accidents. Therefore, rigorous testing of the overall sealing performance is necessary during the production process of rapid-fired nails.

[0003] Currently, the sealing performance of retardant launchers is mostly tested manually or using simple tooling. Manual testing is inefficient, subjective, and yields unreliable results; simple tooling methods are limited in function, unable to accurately detect minute leaks, and inconvenient to operate, making them unsuitable for batch testing. Therefore, we propose an overall sealing performance testing device for retardant launchers to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings mentioned above by proposing a device for detecting the overall sealing performance of continuous firing nails.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for detecting the overall sealing performance of breech-loading nails includes a base and two discs. A positioning platform is fixedly connected to the top of the base, and a positioning and fixing mechanism for positioning and fixing the breech-loading nails is provided on the positioning platform. A sealing head is fixedly connected to the inner side of each disc, and a channel is opened on one side of the sealing head, which communicates with the disc. A pressure sensor is provided on the left disc. A driving mechanism is provided between the positioning platform and the two discs. A mounting bracket is fixedly connected to the top of the base, and a pressurizing mechanism is provided between the mounting bracket and the left disc. A controller with a display screen is fixedly connected to one side of the mounting bracket, and a timer is fixedly connected to the front of the controller.

[0006] As a preferred embodiment of this utility model, the positioning and fixing mechanism includes a positioning groove for positioning the tandem firing nails on the top of the positioning platform and two connecting plates fixedly connected to the top of the positioning platform. A cylinder is fixedly connected to the outer side of the connecting plates, and a clamping plate is fixedly connected to the output shaft of the cylinder.

[0007] As a preferred embodiment of this invention, the two clamping plates are slidably connected to the top of the positioning platform.

[0008] In a preferred embodiment of this invention, the driving mechanism includes a drive motor fixedly connected to the front side of the positioning platform, and a bidirectional lead screw rotatably connected to the inner walls of both sides of the positioning platform. A drive shaft is fixedly connected to the output shaft of the drive motor, and a driving bevel gear is fixedly connected to the rear end of the drive shaft. A driven bevel gear is fixedly sleeved on the outer side of the bidirectional lead screw, and the driving bevel gear meshes with the driven bevel gear. A drive plate is threaded onto the outer side of the bidirectional lead screw, and a movable plate is fixedly connected to the outer side of each of the two drive plates. A vertical plate is fixedly connected to the top of the movable plate, and two discs are fixedly connected to the top of the vertical plate.

[0009] In a preferred embodiment of this invention, both drive plates are slidably fitted inside the positioning platform.

[0010] As a preferred embodiment of this utility model, the pressurizing mechanism includes a pressurizing pump and a storage tank fixedly connected to the top of the mounting frame. The pressurizing pump and the storage tank are connected in communication. The pressurizing pump and the disc on the left side are fixedly connected by the same flexible hose, and a solenoid valve is provided on the flexible hose.

[0011] In a preferred embodiment of this invention, the pressurizing pump, solenoid valve, air pressure sensor, and timer are all electrically connected to the controller.

[0012] As a preferred embodiment of this utility model, a threaded hole is provided on one side of the disc, and an external threaded tube is threaded into the threaded hole. The external threaded tube is fixedly connected to one end of the sealing head, and a sealing ring is fixedly connected to one side of the disc.

[0013] In this utility model, a continuous firing pin overall sealing performance testing device is described. A pre-programmed operating procedure is used via a controller. The continuous firing pin to be tested is placed in the positioning groove. Two cylinders are activated, causing two clamping plates to approach each other and clamp the front and rear sides of the continuous firing pin, completing the positioning and fixing. The controller then activates a drive motor, which drives the drive shaft and the active bevel gear to rotate. The active bevel gear drives the driven bevel gear and the double-acting screw to rotate. The double-acting screw drives two drive plates, a moving plate, a vertical plate, a disc, and two sealing heads to approach each other and insert into the openings at both ends of the continuous firing pin to achieve sealing. Because the sealing heads are designed with a smaller inner diameter and a larger outer diameter, they can be used to seal the openings at both ends of continuous firing pins of different bone specifications, improving the performance. The threaded connection between the threaded hole and the external threaded tube facilitates the disassembly and replacement of the sealing heads. In this utility model, a device for detecting the overall sealing performance of a tandem firing pin involves activating a pressurizing pump and a solenoid valve to pressurize compressed air in a storage tank and inject it through a hose into the channels of the disc and sealing head. This air is then delivered to the inside of the tandem firing pin until a pressure sensor detects that the internal pressure of the tandem firing pin has reached a preset value. After pressurization, the controller stops the pressurizing pump. Simultaneously, a timer is set to monitor the pressurization test time. After a period of time (e.g., 30 seconds, 1 minute, etc.), the pressure sensor detects the pressure change inside the tandem firing pin in real time to determine whether the sealing performance of the tandem firing pin is up to standard. If the pressure change is large, the sealing performance is unsatisfactory; otherwise, it is satisfactory. The test results are displayed on the screen on the controller. After the test is completed, the drive motor is activated in reverse to move the two sealing heads away from each other and disengage them from both ends of the tandem firing pin. The two cylinders are also activated in reverse to prevent the two clamping plates from clamping and fixing the tandem firing pin. The tested tandem firing pin is then removed, and the next test cycle begins. This utility model features a reasonable structural design and a high degree of automation. The controller manages the operation of each mechanism, reducing manual operation and improving testing efficiency. It is suitable for batch testing, offering high accuracy. Combined with a pressure sensor, it can accurately detect sealing issues in rapid-fired nails. Operation is convenient, and a positioning and fixing mechanism ensures accurate positioning of the rapid-fired nails. It is highly versatile; by adjusting the distance between the two sealing heads and replacing them with different specifications of sealing heads, it can be used for testing rapid-fired nails of various sizes.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-4 A device for detecting the overall sealing performance of a series of firing pins includes a base 1 and two discs 5. A positioning platform 2 is fixedly connected to the top of the base 1. A positioning and fixing mechanism 3 for positioning and fixing the series of firing pins is provided on the positioning platform 2. A sealing head 4 is fixedly connected to the inner side of the disc 5. A channel 11 is opened on one side of the sealing head 4 and communicates with the disc 5. A pressure sensor 10 is provided on the left disc 5. A driving mechanism 6 is provided between the positioning platform 2 and the two discs 5. A mounting bracket 15 is fixedly connected to the top of the base 1. A pressurizing mechanism 7 is provided between the mounting bracket 15 and the left disc 5. A controller 8 with a display screen is fixedly connected to one side of the mounting bracket 15. A timer 9 is fixedly connected to the front of the controller 8.

[0018] Furthermore, refer to Figure 1 and Figure 3 The positioning and fixing mechanism 3 includes a positioning groove 31 for positioning the tandem firing nails, which is opened on the top of the positioning platform 2, and two connecting plates 33 fixedly connected to the top of the positioning platform 2. A cylinder 32 is fixedly connected to the outside of the connecting plate 33, and a clamping plate 34 is fixedly connected to the output shaft of the cylinder 32. The two clamping plates 34 are slidably connected to the top of the positioning platform 2.

[0019] Using the above method: Place the continuous firing nail to be tested into the positioning groove 31, start the two cylinders 32, so that the two clamping plates 34 move closer to each other and clamp the front and rear sides of the continuous firing nail to complete the positioning and fixing.

[0020] Furthermore, refer to Figure 1 and Figure 2 The drive mechanism 6 includes a drive motor 61 fixedly connected to the front side of the positioning platform 2, and a bidirectional lead screw 66 rotatably connected to the inner walls on both sides of the positioning platform 2. A drive shaft 64 is fixedly connected to the output shaft of the drive motor 61. A drive bevel gear 63 is fixedly connected to the rear end of the drive shaft 64. A driven bevel gear 65 is fixedly sleeved on the outer side of the bidirectional lead screw 66. The drive bevel gear 63 meshes with the driven bevel gear 65. A drive plate 67 is threaded on the outer side of the bidirectional lead screw 66. A movable plate 68 is fixedly connected to the outer side of each of the two drive plates 67. A vertical plate 62 is fixedly connected to the top of the movable plate 68. Two discs 5 are fixedly connected to the top of the vertical plate 62.

[0021] The above scheme is adopted as follows: the drive motor 61 is started by the controller 8, the drive motor 61 drives the drive shaft 64 and the active bevel gear 63 to rotate, the active bevel gear 63 drives the driven bevel gear 65 and the double-acting screw 66 to rotate, and the double-acting screw 66 drives the two drive plates 67, the moving plate 68, the vertical plate 62, the disc 5 and the two sealing heads 4 to move closer to each other and insert into the openings at both ends of the continuous firing nail to achieve sealing. Because the sealing head 4 is set with the inner smaller and the outer larger, it can be used to seal the openings at both ends of continuous firing nails of different bone specifications, thereby improving the use effect. The threaded connection between the threaded hole 12 and the external threaded tube 13 facilitates the disassembly and replacement of the sealing head 4.

[0022] Furthermore, both drive plates 67 are slidably fitted inside the positioning stage 2, which facilitates the guidance of the drive plates 67 and makes their movement more stable.

[0023] Furthermore, refer to Figure 1 and Figure 4 The pressurization mechanism 7 includes a pressurization pump 71 and a storage tank 72 fixedly connected to the top of the mounting frame 15. The pressurization pump 71 and the storage tank 72 are connected. The pressurization pump 71 and the disc 5 on the left side are fixedly connected by the same hose 73. A solenoid valve 74 is provided on the hose 73. The pressurization pump 71, the solenoid valve 74, the air pressure sensor 10 and the timer 9 are all electrically connected to the controller 8.

[0024] The above scheme is adopted as follows: the pressurizing pump 71 and the solenoid valve 74 are started to pressurize the compressed air in the storage tank 72 and inject it into the channel 11 of the disc 5 and the sealing head 4 through the hose 73. Then it is delivered to the inside of the cascading nail until the air pressure sensor 10 detects that the internal pressure of the cascading nail has reached the preset value. After pressurization is completed, the controller 8 controls the pressurizing pump 71 to stop working. At the same time, the timer 9 can be set to pressurize the detection time. After a period of time (such as 30 seconds, 1 minute, etc.), the pressure sensor 10 detects the pressure change inside the cascading nail in real time to determine whether the sealing performance of the cascading nail is qualified.

[0025] Furthermore, a threaded hole 12 is provided on one side of the disc 5, and an external threaded tube 13 is fitted inside the threaded hole 12. The external threaded tube 13 is fixedly connected to one end of the sealing head 4. A sealing ring 14 is fixedly connected to one side of the disc 5, which facilitates the replacement of the sealing head 4 so that it can be used for firing pins of different specifications.

[0026] In this invention, during use, the controller 8 pre-programs the operation. The continuous firing pin to be tested is placed in the positioning groove 31. The two cylinders 32 are activated, causing the two clamping plates 34 to move closer together and clamp the front and rear sides of the continuous firing pin, completing the positioning and fixing. The controller 8 starts the drive motor 61, which drives the drive shaft 64 and the active bevel gear 63 to rotate. The active bevel gear 63 drives the driven bevel gear 65 and the double-acting screw 66 to rotate. The double-acting screw 66 drives the two drive plates 67, the moving plate 68, the vertical plate 62, the disc 5, and the two sealing heads 4 to move closer together and be inserted into the openings at both ends of the continuous firing pin to achieve sealing. Because the sealing head 4 is designed with a smaller inner diameter and a larger outer diameter, it can be used to seal the openings at both ends of continuous firing pins of different bone specifications, improving the effectiveness of use. The threaded connection between the threaded hole 12 and the external threaded tube 13 facilitates the disassembly and replacement of the sealing head 4.

[0027] The pressurizing pump 71 and solenoid valve 74 are started to pressurize the compressed air in the storage tank 72 and inject it into the channel 11 of the disc 5 and sealing head 4 through the hose 73. Then it is delivered to the inside of the cascading nail until the air pressure sensor 10 detects that the internal pressure of the cascading nail has reached the preset value. After pressurization is completed, the controller 8 controls the pressurizing pump 71 to stop working. At the same time, the timer 9 can be set to pressurize the detection time. After a period of time (such as 30 seconds, 1 minute, etc.), the air pressure sensor 10 detects the pressure change inside the cascading nail in real time to determine whether the sealing performance of the cascading nail is qualified. If the pressure change is large, it means that the sealing performance is unqualified, otherwise it is qualified. The detection result is displayed on the display screen on the controller 8. After the detection is completed, the drive motor 61 is started in reverse so that the two sealing heads 4 are moved away from each other and disengaged from both ends of the cascading nail. The two cylinders 32 are started in reverse so that the two clamping plates 34 do not clamp and fix the cascading nail. The cascading nail after detection is removed and the next detection cycle is performed.
