[0019] Embodiment 1

[0020] This embodiment provides a fixture for drilling a rod end spherical bearing as Figures 1 to 4 shown, which includes a fixture body 1 arranged horizontally. A base 2 protruding downward is provided in the middle of the bottom surface of the fixture body 1. A boss 3 protruding upward is provided in the middle of the upper surface of the fixture body 1. A positioning mandrel 4 is vertically provided in the middle of the upper surface of the boss 3. The lower end of the positioning mandrel 4 is vertically inserted into the fixture body 1. The upper end of the positioning mandrel 4 is located above the boss 3. A through hole 5 penetrating the fixture body 1 is vertically provided in the middle of the positioning mandrel 4. A bolt 6 is vertically provided in the through hole 5. The bolt 6 passes through the positioning mandrel 4 and is threadedly connected to the fixture body 1. Fixing components 7 for fixing the rod end spherical bearing are provided on both the left and right sides of the boss 3.

[0021] During use, first install the parts on the fixture. After installation, place the rod end spherical bearing to be drilled on the positioning mandrel 4, and tightly fix the rod end spherical bearing on the fixture body 1 through the fixing components 7. After placing it, place the entire fixture body 1 vertically and fix it on the lathe, and then the rod end spherical bearing can be drilled by the lathe, thus solving the problem that the rod end spherical bearing cannot be well fixed during each drilling process, resulting in the rod end spherical bearing shaking during drilling, thereby improving the qualified rate of the finally processed finished product and enhancing the work efficiency.

[0022] Further, the fixing component 7 includes two first screw holes 71 vertically formed in the fixture body 1. A first stud 72 threadedly connected to the fixture body 1 is vertically arranged in each first screw hole 71. The first stud 72 can be a double-headed stud. A pressing plate 73 is horizontally arranged on the first stud 72. The pressing plate 73 slidably passes through the first stud 72, and a nut 74 is threadedly sleeved on the first stud 72 above the pressing plate 73.

[0023] Through the provided first screw holes 71, the first studs 72 are firmly fixed to the fixture body 1. Then, the rod end spherical bearing on the fixture body 1 is firmly fixed to the fixture body 1 through the pressing plate 73. Finally, the pressing plate 73 is firmly fixed by the cooperation of the nut 74 and the first stud 72, so that when drilling the rod end spherical bearing, the rod end spherical bearing can be firmly fixed to the fixture body 1, increasing the stability and avoiding the rod end spherical bearing from shaking during processing, thereby improving the qualified rate of the finished product.

[0024] Further, two second screw holes 8 are vertically formed in the fixture body 1. The two second screw holes 8 are respectively located on the left and right sides of the two first screw holes 71. A second stud 9 threadedly connected to the fixture body 1 is vertically arranged in each second screw hole 8. The upper end of the second stud 9 vertically passes through the pressing plate 73, and the second stud 9 is slidably connected to the pressing plate 73. A rotating ring 10 is threadedly sleeved on the part of the second stud 9 between the fixture body 1 and the pressing plate 73.

[0025] When fixing the rod end spherical bearing to the fixture body 1, through the provided rotating ring 10, the height of the pressing plate 73 can be adjusted according to the size specifications of the rod end spherical bearing, so that when the pressing plate 73 fixes spherical bearings of different size specifications, it can firmly fix them, further improving the effect of fixing the spherical bearing to the fixture body 1.

[0026] Further, a counterweight 11 is arranged at the rear side of the upper surface of the fixture body 1. The counterweight 11 is fixed to the fixture body 1 by screws.

[0027] Through the provided counterweight 11, when the fixture body 1 is erected for processing, the counterweight is at the lowermost end, avoiding the rod part of some rod end spherical bearings being too long and shaking due to unstable center of gravity when fixed to the fixture body 1, thereby further improving the stability and fixing effect.

[0028] Further, a round table 12 for placing the head of the bolt 6 is formed at the upper end of the through hole 5 where the positioning mandrel 4 is located.

[0029] Through the provided frustum 12, when the positioning mandrel 4 is fixed by the bolt 6, the head of the bolt 6 (i.e., the nut part) can be stuck inside the positioning mandrel 4, thereby improving the fixing effect of the positioning mandrel 4 fixed on the fixture body 1, making the positioning mandrel 4 tightly fixed on the fixture body 1 and preventing the positioning mandrel 4 from shaking or falling off during machining.

[0030] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or replacements can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
