Description

Technical Field

[0001] This utility model relates to the field of experimental tooling technology, specifically a tool capable of disassembling parts on a mounting plate. Background Technology

[0002] For blind rivets, such as pop rivets, different types of blind rivets manufactured for different fields and specific applications require installation tests to determine their performance. Current installation tests involve mounting the blind rivet onto a mounting plate. Taking a titanium alloy blind rivet as an example, which includes the rivet body and the rivet core, the product needs to be riveted to the mounting plate using specialized riveting tools such as a rivet gun for measurement during testing. Figure 1 As shown, the mounting plate has multiple mounting holes. Multiple blind rivets are installed during installation tests. However, blind rivets have high strength, making it difficult to remove them from the mounting plate after the test. Therefore, most mounting plates used for installation tests are disposable, increasing the cost of the tests. Alternatively, the rivets can be milled off the mounting plate, but this method is costly. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem solved by this utility model is to provide a tool that can disassemble parts on the mounting plate, thereby solving the problem of high installation and testing costs of existing pull-pin fasteners.

[0004] To solve the above problems, the technical solution adopted by this utility model is: a tool for disassembling parts on a mounting plate, including a base, a fixing frame, a ejector pin, and a pressure plate. The base has several through holes, the positions of which correspond to the positions of the blind rivets on the mounting plate. The rivet body of the blind rivet can freely pass through the through holes. The fixing frame has several guide holes corresponding to the positions of the through holes. An ejector pin is provided in the guide holes. The ejector pin is a stepped cylinder. The large end of the ejector pin slides with the guide hole. The diameter of the small end of the ejector pin is smaller than the diameter of the core of the blind rivet. The base has an annular groove. The fixing frame has an annular boss corresponding to the annular groove. The annular boss can extend into the annular groove. The pressure plate is installed on the fixing frame and abuts against the ejector pin.

[0005] Furthermore, the length of the guide hole on the fixing frame is less than the length of the ejector pin.

[0006] Furthermore, the length of the through hole in the base is greater than that of the pop rivet.

[0007] Furthermore, the pressure plate and the fixing frame are fitted with a clearance.

[0008] Furthermore, the large end cylindrical surface of the ejector pin is rounded at the connection with the two side end faces.

[0009] Furthermore, the height of the annular boss is greater than the thickness of the mounting plate.

[0010] The beneficial effects of this solution are as follows: Compared with the prior art, this utility model fixes and limits the mounting plate by setting a base and a fixing frame. The base is provided with a through hole to accommodate the core-pulling rivet on the mounting plate, and the guide hole on the fixing frame is provided with a pin. The pressure plate is used to apply pressure to the pin to push out the core, thereby removing the core-pulling rivet on the mounting plate, so that the mounting plate can be reused and thus reducing the test cost.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Implementation, for example, attached Figures 2 to 5As shown: A tool for disassembling parts on a mounting plate includes a base 1, a fixing frame 2, ejector pins 3, and a pressure plate 4. The base 1 has several through holes 11, the positions of which correspond to the positions of the blind rivets 6 on the mounting plate 5. The rivet body of the blind rivet 6 can freely pass through the through holes 11. The fixing frame 2 has several guide holes 21 corresponding to the positions of the through holes 11. Ejector pins 3 are installed in the guide holes 21. The ejector pins 3 are generally stepped cylinders. The large end of the ejector pin 3 slides in fit with the guide hole 21. The diameter of the small end of the ejector pin 3 is smaller than the diameter of the core of the blind rivet 6. The base 1 has an annular groove 12. The fixing frame 2 has an annular boss 22 corresponding to the annular groove 12. The annular boss 22 can extend into the annular groove 12 to play a positioning role, ensuring the accurate position of the base 1 and the fixing frame 2, and thus ensuring that the ejector pins 3 and the blind rivets 6 are in position. The pressure plate 4 is installed on the fixing frame 2 and abuts against the ejector pins 3. The pressure plate 4 and the fixing frame 2 are in clearance fit for easy removal and placement of the pressure plate 4.

[0019] The length of the guide hole 21 on the fixing frame 2 is less than the length of the ejector pin 3. When the ejector pin 3 is installed into the guide hole 21, its upper part protrudes, making it easy to apply pressure. The length of the through hole 11 of the base 1 is greater than that of the pop rivet 6. The through hole 11 can accommodate the ejected rivet core, making it easy to remove the pop rivet 6. The large end cylindrical surface of the ejector pin 3 is rounded at the connection with the two side end faces, making it easy to put the ejector pin 3 into the guide hole 21. The height of the annular boss 22 is greater than the thickness of the mounting plate 5. In use, the fixing frame 2 presses the mounting plate 5 tightly onto the base 1, and the annular boss 22 can extend into the annular groove 12 on the base 1 to limit the mounting plate 5.

[0020] The specific implementation process is as follows:

[0021] With the base 1 laid flat and its annular groove 12 facing upwards, place the tested mounting plate 5 containing the blind rivet 6 on the base 1, ensuring the rivet body of the blind rivet 6 is positioned within the through hole 11 of the base 1. The lower end face of the mounting plate 5 should abut against the upper end face of the base 1. Install the fixing bracket 2 above the base 1, ensuring the annular boss 22 engages with the annular groove 12. At this point, the fixing bracket 2 presses down on and limits the mounting plate 5, making the guide control hole on the fixing bracket 2 coaxial with the through hole 11. Based on the core size of the blind rivet 6, insert an appropriate ejector pin 3 into the guide hole 21 of the fixing bracket 2. The small end of the ejector pin 3 is brought downwards to abut against the core of the pop rivet 6. At this time, the upper end of the ejector pin 3 protrudes from the guide hole 21 of the fixing frame 2. After the ejector pin 3 is installed, the pressure plate 4 is installed on the fixing frame 2. When the pressure plate 4 is installed, the lower end face of the pressure plate 4 abuts against the upper end face of the ejector pin 3, and pressure is applied to the pressure plate 4. A hydraulic press can be used to apply pressure to the pressure plate 4. Press the ejector pin 3 downwards to push out the core. After the core is pushed out, the rivet body can be easily removed. Multiple pop rivets 6 on the mounting plate 5 can be removed at the same time. The mounting plate 5 can be reused to reduce costs. For rivets of different specifications, the corresponding ejector pin 3 can be replaced.

[0022] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
