[0023] The technical solutions of specific embodiments of this utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the teachings of the following embodiments are within the protection scope of this utility model.

[0024] likeFigure 4 and Figure 5 As shown in the figure, it is one of the nail gun parts 100 in the application, the overall shape of the part 100 is special, the hole is not centrally arranged, and it has many convex and concave structures. The overall structure and shape are very complex. If the conventional hole positioning method is used for clamping, the clamping will not be firm. In order to solve this problem and make the part 100 be reliably and firmly clamped and fixed, the application proposes a new structure of nail gun part processing tool. The processing tool uses the shape and structure of the part 100 itself, and adopts the way of top lap, side positioning and side pressure to realize firm clamping and fixing.

[0025] Specifically, referring to Figures 1-5 In this embodiment, the nail gun part processing tool comprises a base 1, a lap positioning base 2 and a base assembly. The base 1 is integrally formed with a connecting body 1-1 on the front and rear sides. The top of the connecting body 1-1 is lower than the top of the base 1, and the top of the connecting body 1-1 gradually inclines downward from inside to outside. A plurality of connecting holes 1-2 are formed in the connecting body 1-1. Thus, the structure of the base 1 has a higher and central top and lower connecting bodies 1-1 on the front and rear sides. The higher and central top can be used as the installation carrier of each part, and the lower connecting bodies 1-1 can shorten the depth of the connecting holes 1-2, so as to facilitate the installation of the base 1 on the processing equipment.

[0026] The lap positioning base 2 is fixedly installed on one end of the top of the base 1, and the base assembly comprises a fixed base 3 fixedly installed on the other end of the top of the base 1, a pressing base 4 slidingly installed on the top of the fixed base 3, and a driver 5 driving the pressing base 4 to slide along the fixed base 3. The pressing base 4 can approach or move away from the lap positioning base 2. The lap positioning base 2 forms top loading and side positioning for the member to be clamped (the part 100), and the pressing base 4 forms side pressure for the member to be clamped.

[0027] Therefore, through the cooperation of the above-mentioned structure parts, when the pressing base 4 moves away from the lap positioning base 2, there is enough distance between the pressing base 4 and the lap positioning base 2. At this time, the part 100 can be placed between the two, and initially placed on the lap positioning base 2 in the way of top loading and side positioning. Then, the driver 5 is started to drive the pressing base 4 to press the part 100, so as to realize firm clamping and fixing.

[0028] In the embodiment, the pressing base 4 is mainly realized by the following structure. Specifically, the pressing base 4 comprises a bottom sliding block 4-1, a main base body 4-2 and a pressing block 4-3 which are sequentially fixedly connected. The bottom sliding block 4-1 is slidingly connected in a sliding groove 3-1 on the top of the fixed base 3. The pressing block 4-3 is fixedly installed on the main base body 4-2 at the side opposite to the lapping positioning base 2. Through the cooperation of the sliding groove 3-1 and the bottom sliding block 4-1, the pressing base 4 can run along the sliding groove 3-1 on the fixed base 3, thereby ensuring smooth sliding along the desired path.

[0029] In actual assembly, the driver 5 preferably drives a cylinder whose cylinder body is fixedly installed at the other end of the top of the base 1. The output end of the cylinder is connected with the end of the bottom sliding block 4-1. Under the driving of the cylinder, the bottom sliding block 4-1 can slide along the sliding groove 3-1 to press the component 100, and after machining, the bottom sliding block 4-1 can also slide along the sliding groove 3-1 away from the lapping positioning base 2 to realize the disassembly of the component 100.

[0030] The lapping positioning base 2 in the embodiment comprises a connecting base body 2-1 and a lapping positioning base body 2-2. The connecting base body 2-1 is fixedly installed at one end of the top of the base 1. The lapping positioning base body 2-2 is fixedly installed at the side of the connecting base body 2-1 opposite to the pressing base 4. Thus, the lapping positioning base 2 and the base assembly are correspondingly arranged at the two ends of the top of the base 1.

[0031] In the embodiment, in order to realize the top lapping and lateral positioning of the component 100, the side of the lapping positioning base body 2-2 opposite to the pressing base 4 is configured with a positioning top cavity 7 which is penetrated at the top and the outer side. Symmetrical lapping concave cavities 8 are arranged at the two sides of the top of the positioning top cavity 7. The positioning top cavity 7 is used for sleeving the top side 100-1 of the to-be-clamped member for positioning. The lapping concave cavities 8 are used for lapping the radially protruding top connecting blocks 100-2 on the to-be-clamped member.

[0032] Meanwhile, the side of the lapping positioning base body 2-2 opposite to the pressing base 4 is also configured with a pasting shallow cavity 9 which is used for sleeving the side wall 100-3 of the to-be-clamped member for positioning. The side of the lapping positioning base body 2-2 opposite to the pressing base 4 is also configured with an end cavity 10 which is penetrated at the side and the end. The end cavity 10 is used for sleeving the end connecting section 100-4 of the to-be-clamped member for positioning. The side of the lapping positioning base body 2-2 opposite to the pressing base 4 is also configured with a bottom cavity 11 which is penetrated at the side, the bottom and the two ends. The bottom cavity 11 is used for sleeving the main connecting section 100-5 of the to-be-clamped member for positioning.

[0033] In actual clamping, the part 100 can be initially placed on the lap joint positioning base 2-2 in a way of being sleeved by the side and overlapped by the top. The top and side of the lap joint positioning base 2-2 are not all shaped according to the side of the part 100, but are optimized and screened, and each cavity which must be added and has a better effect on firmness is cooperatively arranged. Thus, the large-area shaped design is saved, and the part 100 is firmly clamped.

[0034] As further structural optimization of the lap joint positioning base 2-2, a middle convex body 12 is further arranged on the side of the lap joint positioning base 2-2 opposite to the pressing base 4, and the to-be-clamped component is sleeved into the middle convex body 12 to be positioned. With the middle convex body 12, the positioning stability is further improved.

[0035] The side of the pressing block 4-3 opposite to the lap joint positioning base 2 is provided with a pressing side wall 13 which presses the top side wall 100-7 of the to-be-clamped component opposite to the top side 100-1. The top side wall 100-7 has a relatively flat wall surface, and the to-be-clamped component 100 is tightly pressed on the lap joint positioning base 2-2 by the pressing side wall 13, thereby achieving stable clamping.

[0036] Further, the pressing side wall 13 is further provided with an inner recessed groove 14 which is opposite to the top cylindrical side wall 100-8 of the to-be-clamped component opposite to the top side 100-1. For some parts 100 with an inaccurate size of the top cylindrical side wall 100-8, the inner recessed groove 14 can avoid and press the slightly convex top cylindrical side wall 100-8.

[0037] The embodiments of the application are described above in combination with the drawings, but the application is not limited to the above specific embodiments, and the above specific embodiments are only illustrative but not restrictive. Those skilled in the art can make many forms under the guidance of the application without departing from the scope of the application and the protection scope of the claims.
