[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Example 1: Reference Figures 1 to 3 This application provides a plugging installation device for plugging workpiece holes, including a plugging head 1, which includes a plugging head 11, a limiting part 12, and a fixing member 13. A plugging member 4 is provided at one end of the plugging head 11 for inserting into the workpiece hole. The other end of the plugging head 11 is connected to one end of the limiting part 12, the outer diameter of which is larger than the outer diameter of the plugging head 11. The fixing member 13 is connected to the other end of the limiting part 12, and a fixing protrusion 14 is provided at the end of the fixing member 13 away from the limiting part 12. A clamp assembly 2 is also provided. It includes a fixing part 21 and a limiting member 26. The fixing part 21 has a cavity extending through both ends. The fixing member 13 is disposed in the cavity. The outer wall of the fixing part 21 has a limiting hole 27 communicating with the cavity. The limiting member 26 is disposed in the limiting hole 27 and abuts against the fixing protrusion 14 to restrict the movement of the fixing member 13 and fix the fixing member 13 in the cavity. The mounting part 3 is connected to the clamp assembly 2. The mounting part 3 is used to push the plugging head 1 so that the plugging member 4 on the plugging head 11 is inserted into the workpiece plugging hole.

[0025] In this embodiment, the plug head 11 is a cylindrical structure made of metal to withstand the friction and pressure during the insertion of the workpiece into the hole. The plug 4 covers the plug head 11 for easy assembly and disassembly. In one embodiment, the plug head 11 and the plug 4 are connected by a threaded connection. The end of the plug head 11 is provided with an internal thread, while the plug 4 is provided with a matching external thread. This facilitates the secure installation of the plug 4 and allows for timely disassembly and replacement. The shape of the plug 4 can also be adapted to the shape of the workpiece hole. If it is a circular hole, the plug 4 is a cylinder of the corresponding size, and its outer surface can be appropriately frosted to increase the friction with the inner wall of the hole and achieve a better sealing effect.

[0026] The limiting part 12 is cylindrical, and its outer diameter is larger than that of the plug head 11 to prevent the plugging head 1 from being excessively inserted into other parts of the mounting device. The limiting part 12 and the plug head 11 are integrally formed to make the connection between the limiting part 12 and the plug head 11 more secure.

[0027] The fastener 13 is elongated and is used to be stably installed in the cavity of the clamp assembly 2. The material of the fastener 13 is consistent with that of the plug head 11 and the limiting part 12. It is also integrally formed with the limiting part 12 to ensure the overall strength and stability.

[0028] The fixing protrusion 14 is located at the end of the fixing member 13 away from the limiting part 12. The fixing protrusion 14 is an annular boss structure, which is arranged around the outer circumference of the fixing member 13. Its height is based on the depth of the limiting hole 27 to ensure that when it cooperates with the limiting part 26, it can stably restrict the axial movement of the fixing member 13 in the cavity.

[0029] The fixing part 21 has an overall cylindrical structure, and the inner diameter of its cavity is adapted to the outer diameter of the fixing member 13. The two are in a clearance fit, which ensures that the fixing member 13 can move smoothly in the cavity without the fixing member 13 shaking in the cavity due to excessive clearance, thus affecting the accuracy of the blocking operation. The fixing part 21 can be made of high-strength engineering plastics or metal materials to have sufficient strength to withstand the forces generated when the fixing member 13 moves inside it and connects with other components.

[0030] The limiting hole 27 is formed on the outer wall of the fixing part 21. It is circular in shape and its diameter is slightly larger than the outer diameter of the limiting member 26, so as to facilitate the installation and removal of the limiting member 26. The position of the limiting hole 27 corresponds to the position of the fixing protrusion 14 on the fixing member 13, so that the limiting member 26 can abut against the fixing protrusion 14 after insertion, thereby playing a limiting role.

[0031] When the limiting member 26 is inserted into the limiting hole 27, its other end abuts tightly against the fixing protrusion 14, which can restrict the movement of the fixing member 13 in the cavity and ensure that the blocking head 1 is in a stable installation position when not in operation.

[0032] One end of the mounting component 3 is connected to the fixing part 21 of the clamp assembly 2. The connection method can be threaded connection or snap-fit ​​connection, etc., to ensure a firm and reliable connection. The other end of the mounting component 3 is provided with a handle structure that is easy to hold and operate. The shape of the handle can be designed according to ergonomics, such as using an arc shape and a non-slip texture, to make it easy for the operator to grip and apply pushing force.

[0033] In use: Insert the fastener 13 into the fixing part 21, and the fastener 13 is fixed in the fixing part 21 by the limiting member 26 and the fixing protrusion 14, so as to prevent the fastener 13 from falling out of the fixing part 21. When it is necessary to insert the plug 4 into the plug hole, when the plugging operation is required, the limiting part 26 is taken out, the operator holds the handle of the mounting part 3, and by applying axial thrust, the mounting part 3 pushes the plugging head 1 in the clamp assembly 2 to move towards the workpiece plugging hole, and finally the plug 4 on the plug head 11 is accurately inserted into the workpiece plugging hole to achieve the purpose of plugging. Then the plug head 11 is removed from the plug 4 to complete the plugging.

[0034] In one feasible embodiment, the mounting component 3 can also be an automatically pushing device. Taking a rivet gun as an example, the operator holds the rivet gun and applies an axial thrust to the mounting component 3 through the rivet gun, so that the mounting component 3 pushes the plugging component 4 in the clamp assembly 2 toward the workpiece plugging hole direction, and inserts the plugging component 4 into the plugging hole.

[0035] By adopting the above technical solution, the plugging component 4 can be automatically inserted into the process hole, the plugging component 4 can be quickly installed and replaced, and the whole device has a simple structure and can effectively ensure the installation depth.

[0036] Example 2: Reference Figure 2 In one feasible embodiment, the plug 4 is sleeved on the end of the plug head 11, and the end of the plug head 11 has an annular groove 16. An O-ring 15 is provided in the annular groove 16, and the O-ring 15 is used to fix the plug 4 on the plug head 11.

[0037] In this embodiment, the depth and width of the annular groove 16 222 at the end of the plug head 11 are determined according to the specifications of the selected O-ring 15. The depth of the groove 222 is slightly smaller than the cross-sectional diameter of the O-ring 15, so that a portion of the O-ring 15 can protrude from the groove 222 after installation, thus providing a sealing and fixing function. The width of the groove 222 is used to ensure that the O-ring 15 is tightly placed within it, preventing it from easily coming out under pressure or other conditions.

[0038] The inner wall of the annular groove 16 is polished to make its surface smooth, reducing wear on the O-ring 15 and extending its service life. Meanwhile, chamfers are provided at both edges of the annular groove 16 to facilitate the installation of the O-ring 15 and prevent scratching it during installation.

[0039] The connection between the plug head 11 and the plug 4 is assisted by an O-ring 15 for fixation. When the plug 4 is fitted onto the end of the plug head 11, the O-ring 15 is squeezed and deformed in the annular groove 16, filling the gap between the plug 4 and the plug head 11. On the one hand, it can prevent the plug 4 from axially displacing relative to the plug head 11 due to vibration or other reasons during use, ensuring that the plug 4 can always maintain an accurate position aligned with the workpiece hole. On the other hand, the O-ring 15 also plays a certain sealing role, preventing external impurities from entering the connection between the plug head 11 and the plug 4, affecting the fit between the two and the overall plugging effect.

[0040] Example 3: Continue to refer to Figure 2 In one feasible embodiment, along the extending direction of the plug head 11, the plug head 11 is also provided with a stepped annular protrusion 17. When the plug 4 is installed on the plug head 11, the end of the plug 4 abuts against the annular protrusion 17 to limit the plug 4.

[0041] In this embodiment, the plug head 11 has a stepped annular protrusion 17 along its extension direction. The height of the annular protrusion 17 is slightly less than the thickness of the plug 4 in the installation direction. When the plug 4 is fitted onto the plug head 11, the end of the plug 4 abuts tightly against the annular protrusion 17, which plays a precise limiting role.

[0042] The outer periphery of the annular protrusion 17 is rounded to prevent the edge from scratching the plug 4 or affecting its smooth installation during the installation process. The rounded corners also make the entire structure smoother in appearance, reduce stress concentration points, and improve the overall durability of the structure.

[0043] The annular protrusion 17 and the plug head 11 are integrally formed, which improves the overall connection strength and prevents the protrusion from falling off or being damaged due to force during use, thereby ensuring a stable and reliable limiting function for the plug part 4.

[0044] Meanwhile, there is a certain distance between the annular groove 16 and the annular protrusion 17, ensuring that the O-ring 15 can fully play its role in fixing the plug 4, while also ensuring that the annular protrusion 17 can effectively limit the plug 4. In this application, the annular groove 16 is close to the edge of the end of the plug head 11, while the annular protrusion 17 is located slightly inside the end, so that the plug 4 is installed on the plug head 11 in a firm and precise manner.

[0045] Example 4: Continue to refer to Figure 1 and Figure 2 In one feasible embodiment, the outer diameter of the limiting part 12 is larger than the outer diameter of the plug 4, and the limiting part 12 is also provided with an anti-collision pad 18 on the side facing the plug head 11. When the mounting part 3 pushes the plug head 1 to insert the plug 4 into the workpiece plug hole, the anti-collision pad 18 abuts against the outer surface of the workpiece.

[0046] In this embodiment, the outer diameter of the limiting part 12 is larger than the outer diameter of the blocking part 4. This is to maximize the contact area with the workpiece without interfering with the normal insertion of the blocking part 4 into the workpiece hole, so as to better distribute the pressure and ensure that the workpiece surface will not be damaged due to excessive local pressure when it comes into contact with the workpiece through the anti-collision pad 18.

[0047] The anti-collision pad 18 can be made of materials with good elasticity and cushioning properties, such as rubber or polyurethane. Its shape can be a ring structure that fits snugly against the limiting part 12, and it can be fixed to the side of the limiting part 12 facing the plug head 11 using appropriate installation methods such as adhesive or clips. The thickness of the anti-collision pad 18 is determined based on the magnitude of the potential impact force and the requirements for protecting the workpiece surface, generally around 3-8 mm, to avoid insufficient cushioning while affecting the compactness and operational flexibility of the entire device.

[0048] The outer surface of the anti-collision pad 18 has textures or tiny protrusions. On the one hand, this increases the friction with the workpiece surface, preventing relative slippage during operation and affecting the anti-collision effect; on the other hand, it also helps to disperse pressure to a certain extent, further protecting the workpiece surface. At the same time, the edges of the anti-collision pad 18 are rounded to avoid sharp edges scratching the workpiece.

[0049] Example 5: Continue to refer to Figure 1 In one feasible embodiment, the clamp assembly 2 further includes a limiting sleeve 22, which is sleeved on the outer wall of the fixing part 21. When the limiting member 26 fixes the fixing member 13 in the cavity, the limiting sleeve 22 can move to the limiting hole 27 to fix the limiting member 26 in the limiting hole 27.

[0050] In this embodiment, the limiting sleeve 22 is cylindrical in shape. Its inner diameter is designed according to the outer diameter of the part of the limiting member 26 that extends out of the limiting hole 27 to ensure that there is a suitable clearance fit between the two. The length of the limiting sleeve 22 is sufficient to completely cover the limiting hole 27 and the part of the extending limiting member 26 to ensure that the limiting member 26 can be stably fixed in the limiting hole 27 and prevent it from accidentally coming out.

[0051] On the outer peripheral surface of the limiting sleeve 22, some anti-slip textures or protrusions can be provided to facilitate the operator to hold and push it on the outer side wall of the fixing part 21 and accurately position it at the limiting hole 27.

[0052] The limiting sleeve 22 can be made of engineering plastic, which has a certain strength to ensure the fixing effect of the limiting part 26, and is lightweight, making it convenient for operators to move and operate.

[0053] Example 6: Continue to refer to Figure 1 In one feasible embodiment, the outer wall of the fixing part 21 is also provided with an annular groove 25, and the limiting sleeve 22 is sleeved on the annular groove 25. The clamp assembly 2 also includes a retaining spring 23 and an elastic member 24. The retaining spring 23 is disposed on one side of the groove wall of the annular groove 25, and one side of the elastic member 24 is connected to the other side of the groove wall of the annular groove 25. The limiting sleeve 22 is connected to the other side of the elastic member 24. The elastic member 24 is used to push the limiting sleeve 22 to abut against the retaining spring 23. When the limiting sleeve 22 abuts against the retaining spring 23, the limiting sleeve 22 is located at the limiting hole 27.

[0054] In this embodiment, an annular groove 25 is formed on the outer wall of the fixing part 21. The retaining spring 23 is installed on one side of the groove wall of the annular groove 25, and the part that contacts the limiting sleeve 22 has an optimized shape, so that the limiting sleeve 22 and the retaining spring 23 make arc-shaped contact, increasing the contact area with the limiting sleeve 22. This makes the force on the limiting sleeve 22 more uniform when it abuts against the retaining spring 23, improving the stability of the fixation. The retaining spring 23 should be made of spring steel with high elastic modulus and good fatigue resistance, and manufactured by precision stamping or winding process to ensure that it will not deform or break during long-term repeated stress.

[0055] The elastic element 24 is a helical spring. The steel wire of its material has suitable elasticity and strength. Its mechanical properties are adjusted through heat treatment to provide stable and appropriate elastic force, pushing the limiting sleeve 22 to abut against the retaining ring 23. The pitch, outer diameter, inner diameter, and effective number of turns of the helical spring must be precisely calculated and designed to ensure that it fits the installation space in the annular groove 25 and that there will be no jamming or skewing during compression and rebound.

[0056] The connection between the elastic element 24 and the wall of the annular groove 25 and the limiting sleeve 22 can be achieved by fixing one end to the other side of the annular groove 25 by welding, riveting, or other means, and the other end to the limiting sleeve 22 can be connected by hooks, slots, or other structures to ensure that the elastic element 24 will not detach during the extension and retraction process, so that the entire limiting sleeve 22 can move accurately to the limiting hole 27 under the action of elastic force and stably abut against the snap ring 23.

[0057] The limiting sleeve 22 has an overall cylindrical structure. Its inner diameter needs to be precisely designed in conjunction with the outer diameter of the portion of the limiting member 26 extending out of the limiting hole 27 and the size of the retaining spring 23 to ensure a good fit between the three components. This allows the limiting sleeve 22 to smoothly abut against the retaining spring 23 under the push of the elastic member 24, and to tightly fix the limiting member 26, preventing it from accidentally coming off. The length of the limiting sleeve 22 must take into account the length requirements of covering the limiting hole 27 and the extended portion of the limiting member 26.

[0058] Example 7: Continue to refer to Figure 1 In one feasible embodiment, the limiting sleeve 22 is further provided with an abutment protrusion 221, and the elastic member 24 is connected to the abutment protrusion 221. When the elastic member 24 pushes the limiting sleeve 22 to abut against the retaining spring 23, the abutment protrusion 221 is located at the limiting hole 27, and the limiting member 26 abuts against the abutment protrusion 221. The limiting sleeve 22 is also provided with a groove 222. When the limiting sleeve 22 moves to the other side of the annular groove 25, the groove 222 faces the limiting hole 27. The side of the fixing protrusion 14 facing the limiting member 26 is set at an angle to the axis of the fixing member 13. When the groove 222 faces the limiting hole 27, the fixing member 13 can push the limiting member 26 partially into the groove 222.

[0059] In this embodiment, the abutment protrusion 221 on the limiting sleeve 22 can be semi-circular, trapezoidal, etc., with appropriate height and width. This ensures sufficient contact area with the limiting member 26 for stable abutment, while avoiding excessive size that could affect the overall structural strength of the limiting sleeve 22 and its flexibility of movement within the annular groove 25. Similarly, the groove 222 on the limiting sleeve 22 should be rationally designed based on the dimensions of the limiting member 26 and the mounting part fixing protrusion 14. The depth of the groove 222 should ensure that when the limiting sleeve 22 moves to the corresponding position, the mounting part fixing protrusion 14 can smoothly push the limiting member 26 out of the limiting hole 27 and accommodate it within the groove 222. Simultaneously, the width of the groove 222 should be slightly larger than the outer diameter of the limiting member 26 to ensure sufficient movement space for the limiting member 26 within the groove 222, preventing jamming. The inner wall of the groove 222 should be smoothed to reduce the friction when the limiting member 26 enters and exits the groove 222, and a chamfer can be set at the edge of the groove 222 to prevent the limiting member 26 from being scratched when entering and exiting.

[0060] The inclined surface of the fixed protrusion 14 facilitates the ejection of the limiting member 26 from the limiting hole 27, preventing the fixed protrusion 14 from getting stuck with the limiting member 26 and causing damage to the fixing member 13 when it is pushed.

[0061] Example 8: Continue to refer to Figure 1 In one feasible embodiment, the limiting member 26 is a steel ball. When the fixing member 13 is installed in the fixing part 21, the steel ball is placed into the limiting hole 27, and the fixing member 13 is fixed in the fixing part 21 by the steel ball. Under the push of the elastic member 24, the abutting protrusion 221 of the limiting sleeve 22 abuts against the steel ball, restricting the steel ball in the limiting hole 27 and preventing the fixing member 13 from sliding. When installation is required, the limiting sleeve 22 is pulled so that the groove 222 is aligned with the steel ball. When the fixing member 13 is pushed out of the fixing part 21, the fixing protrusion 14 pushes the steel ball out of the limiting hole 27 to the groove 222 of the limiting sleeve 22, so that the steel ball will not pop out after the fixing member 13 leaves the fixing part 21.

[0062] Example 9: In one feasible embodiment, the mounting member 3 is installed in the cavity, and the inner sidewall of the cavity is provided with an internal thread. The mounting member 3 is provided with an external thread corresponding to the internal thread, so that the cavity and the mounting member 3 are threadedly connected.

[0063] In this embodiment, the mounting part 3 and the inner wall of the cavity of the fixing part 21 are threaded together to achieve a tight and smooth thread fit, improve reliability and anti-loosening ability, avoid the mounting part 3 from shifting or shaking due to loosening during the operation of the device, and ensure the accuracy and stability of the blocking operation.

[0064] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
