[0002] The switch trigger of the electric tool angle grinder is composed of four parts: a cylindrical pin, a self-locking button, a button spring, and a trigger. The assembly of the switch trigger is divided into four steps: first, insert the cylindrical pin into the hole on the right side of the trigger, then install the self-locking button, put in the spring, and then put in the positioning tool to knock the cylindrical pin into the trigger with the help of external force. During the installation of the cylindrical pin, it is necessary to use external force to knock the cylindrical pin into the trigger hole. However, in this process, it is easy for the limit lengths of the two ends of the cylindrical pin to be different, and the cylindrical pin is easy to skew when knocking the trigger. The knocked surface of the trigger will have pits or bumps, and the manual assembly efficiency is low, and there is even a safety issue of hurting the hands. In order to solve the above problems, a pneumatic tool for assembling the switch trigger is proposed. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-4 As shown, a pneumatic tooling for assembling a switch trigger includes a mounting base 1, one end of the mounting base 1 is provided with a pneumatic mechanism 2 for assembling the switch trigger, the other end of the mounting base 1 is provided with a positioning assembly 3 used in conjunction with the pneumatic mechanism 2, a positioning mold 4 is provided between the pneumatic mechanism 2 and the positioning assembly 3, and the positioning mold 4 is fixed on the mounting base 1.

[0021] The present invention changes the original step of manually tapping the trigger to install the cylindrical pin 11 into a pneumatic installation through the cooperation of the provided pneumatic mechanism 2 and the positioning component 3, which not only improves the degree of automation of the trigger assembly, but also ensures the installation accuracy. After the cylindrical pin 11 is inserted into the trigger, it can be concentric and the limit lengths at both ends are the same. The installation of the pneumatic mechanism 2 accelerates the speed of installing the cylindrical pin 11, greatly shortens the production cycle, and reduces the labor intensity and physical consumption of the operator by manually installing the cylindrical pin 11, as well as the fatigue and work-related injury risks that may be caused. It is safe and improves efficiency.

[0022] Specifically, the pneumatic mechanism 2 includes a cylinder 21, which is mounted on one end of the mounting base 1. A first fixing base 22 is fixedly connected to the end of the mounting base 1 closest to the cylinder 21. The piston rod of the cylinder 21 extends through the first fixing base and outward. This design, through the provision of the first fixing base 22, can provide a positioning function for the piston rod of the cylinder 21, while also facilitating the securement of the cylinder 21 on the mounting base 1, thereby providing a pneumatic effect for trigger assembly.

[0023] Specifically, the positioning assembly 3 includes a second fixing base 31, which is fixed to the other end of the mounting base 1. A guide rod 32 is fixedly connected to the second fixing base 31. The above design facilitates the installation of the guide rod 32 through the provision of the second fixing base 31, and can provide a guiding and positioning function when the cylindrical pin 11 is installed.

[0024] Specifically, the position of the guide rod 32 corresponds to the position of the piston rod of the cylinder 21. A slot 5 is defined on the opposing sides of the guide rod 32 and the piston rod of the cylinder 21. An ejector pin 6 is secured within the slot 5, and a buckle 7 is secured to the outside of the slot 5 for securing the ejector pin 6. This design allows ejector pin 6 to be mounted in the slots 5 defined in the guide rod 32 and the piston rod of the cylinder 21. This allows for quick installation of the cylindrical pin 11, while also ensuring that the two ends of the cylindrical pin 11 are not at the same length during installation.

[0025] Specifically, one side of the surface of the positioning mold 4 is provided with a trigger shape positioning mold cavity 8, and the other side is provided with a groove 9. Through holes 10 are provided on both sides of the positioning mold 4 and between the groove 9 and the trigger shape positioning mold cavity 8. A cylindrical pin 11 is placed in the groove 9 at a position corresponding to the through hole 10. The above design, by providing the trigger shape positioning mold cavity 8 on the positioning mold 4 to facilitate the placement of the trigger, then placing the cylindrical pin 11 in the groove 9, and through the through hole 10, the cylinder 21 pushes the cylindrical pin 11 to quickly install it on the trigger, thereby improving the efficiency of trigger installation.

[0026] Specifically, one end of the ejector pin 6 mounted on the guide rod 32 is inserted into the through-hole 10 on one side of the positioning mold 4, while the ejector pin 6 mounted on the piston rod of the cylinder 21 is movably connected to the through-hole 10 on the other side of the positioning mold 4. This design ensures that the two ends of the cylindrical pin 11 are aligned during installation, providing a position limit for the insertion of the cylindrical pin 11.

[0027] Specifically, the groove 9 includes an upper notch 91 and a lower notch 92. In order to facilitate the manual placement of the cylindrical pin 11 on the positioning mold 4, the cylindrical pin 11 is placed at the connection between the upper notch 91 and the lower notch 92 and corresponds to the position of the through hole 10, ensuring that the position of the cylindrical pin 11 can be aligned with the position of the through hole 10.

[0028] During specific use, first, the positioning assembly 3, the positioning mold 4 and the pneumatic mechanism 2 are installed on the mounting seat 1 in sequence and fixed, and then the trigger model is placed in the trigger shape positioning mold cavity 8 opened by the positioning mold 4, and then the cylindrical pin 11 is placed at the connection between the upper recess 91 and the lower recess 92 to ensure that the position of the cylindrical pin 11 can be aligned with the position of the through hole 10, and then the cylinder 21 in the pneumatic mechanism 2 is started to drive the ejector pin 6 on the piston rod to push the cylindrical pin 11, so that the cylindrical pin 11 can be quickly installed on the trigger, solving the operation of manually tapping the trigger to install the cylindrical pin 11, avoiding the cylindrical pin 11 from being easily skewed when tapping the trigger and the occurrence of pits or bumps on the tapped surface of the trigger. When the cylindrical pin 11 is inserted into the trigger, the guide rod 32 in the positioning assembly 3 and the ejector pin 6 installed on the guide rod 32 play a positioning and guiding role on the cylindrical pin 11, thereby ensuring that the length of the two ends of the cylindrical pin 11 is uniform, thereby improving the safety and processing efficiency of the trigger assembly.
