[0002] Gears are an important transmission component that can change the direction of power, transmit power, and adjust speed and torque. The processing of gears involves multiple steps, mainly including blank manufacturing, cutting and heat treatment. Gears are widely used in various mechanical equipment.

[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Figure 1-3 As an embodiment of the utility model, a drilling device for gear forgings comprises a workbench 1, a drilling unit 2 is arranged above the workbench 1, and a positioning mechanism 3 for positioning and adjusting the position of the gear is arranged on the upper surface of the workbench 1;

[0027] The positioning mechanism 3 includes a turntable 31 rotatably connected to the upper surface of the workbench 1, and three positioning blocks 32 arranged in a circumferential array are slidably connected to the upper surface of the turntable 31. The lower surface of the turntable 31 is rotatably connected to a driving disk 33, and the driving disk 33 is provided with three inclined grooves 34. The bottom of the positioning block 32 is slidably connected in the inclined groove 34.

[0028] The positioning mechanism 3 further includes a driving component 35 for rotating the driving disk 33 .

[0029] In actual use, when it is necessary to drill a hole in the gear, the gear is placed on the turntable 31, so that the driving disk 33 rotates, and the position of the inclined groove 34 on the driving disk 33 changes, so that the positioning block 32 slides under the guidance of the inclined groove 34 and the restriction of the slide groove on the turntable 31, and the positioning block 32 moves toward the gear. When the positioning block 32 moves to contact the outer surface of the gear, the position of gears of different sizes is fixed. The drilling unit 2 is adjusted according to the drilling position and needs for drilling. The gear position is stable during the drilling process, which can effectively improve the accuracy of the drilling process.

[0030] Specifically, the driving component 35 includes a worm wheel 351 fixed to the bottom of the driving disk 33, and a worm 352 meshing with the worm wheel 351 is arranged on the side of the worm wheel 351, and one end of the worm 352 passes through the outer circumferential surface of the turntable 31 and is fixed with a knob 353; in actual use, when it is necessary to fix the gear on the upper surface of the turntable 31, the knob 353 is turned to rotate the worm 352, and the worm wheel 351 rotates under the drive of the worm 352, thereby rotating the driving disk 33, so that the positioning block 32 moves to realize the positioning of the gear.

[0031] More specifically, the positioning block 32 is shaped like an inverted T, and a rubber pad 36 is fixed on the inner side of the positioning block 32 to protect the outer surface of the gear. In actual use, when the positioning block 32 is driven by the driving disk 33 to move to contact the outer surface of the gear, by arranging the rubber pad 36 on the side of the positioning block 32, when the positioning block 32 contacts the gear, the rubber pad 36 can protect the outer surface of the gear and make the positioning block 32 more stable when fixing the gear.

[0032] More specifically, a groove is provided on the upper surface of the workbench 1, and the turntable 31 is located in the groove. A rotating cylinder 37 is fixed in the groove. A circular hole penetrating the worm gear 351 is opened on the driving disk 33, and the protruding end of the rotating cylinder 37 is fixed to the bottom surface of the turntable 31 through the circular hole. The longitudinal cross-section of the turntable 31 is a U-shape with the opening facing downward. In actual use, when drilling is required at different positions on the gear, the turntable 31 is rotated by controlling the rotating cylinder 37, thereby driving the gear fixed on the turntable 31 to rotate to a suitable position, so as to facilitate drilling at different positions on the gear.

[0033] Specifically, a plurality of sockets are provided on the upper surface of the workbench 1, and baffles 4 are inserted in the sockets to prevent debris generated during the drilling process from splashing. In actual use, after the gear is fixed with the positioning block 32, the baffle 4 is moved above the workbench 1 so that the insertion rod at the bottom of the baffle 4 corresponds to the socket, and the baffle 4 is inserted on the workbench 1 to block the debris splashed during the drilling process, thereby improving the safety of the drilling process.

[0034] More specifically, a filter screen 5 is fixed on the inner circumferential surface of the baffle 4 for filtering debris generated during the drilling process. The filter screen 5 is annular, and the inner circumferential surface of the filter screen 5 is slidably connected to the outer circumferential surface of the turntable 31. In actual use, the filter screen 5 is arranged on the inner circumferential surface of the baffle 4 to block the gap between the turntable 31 and the inner wall of the groove, so that the splashing debris or the debris blocked by the baffle 4 falls on the filter screen 5, which can effectively reduce the debris from falling into the groove. After the drilling is completed, the baffle 4 is taken out to dump and clean the debris on the filter screen 5, thereby improving the debris cleaning efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
