Description

Technical Field

[0001] This utility model relates to the field of advance advance cover processing technology, specifically a drilling and positioning device for advance advance cover processing. Background Technology

[0002] The engine injection advance mechanism is a crucial intelligent adjustment device in the engine's fuel system. Its core function is to automatically adjust the injection advance angle based on changes in engine speed.

[0003] In the prior art, patent announcement number CN210829567U discloses a good protective advance device, including a cover, an advance device body is provided in the inner cavity of the cover, one side of the advance device body extends to the outside of the cover, a sealing gasket is fixedly connected to the inner cavity of the cover and located on the surface of the advance device body, the cover includes an inner shell part and an outer end part, the cover is a grooved thin shell structure, a reinforcing rib is fixedly connected to the rear end of the inner shell part, and the reinforcing rib is equidistantly and symmetrically distributed at the rear end of the inner shell part.

[0004] The edge of the advance advance cover has a series of mounting holes, which are usually arranged in a circular array on the outer circumference of the cover. These mounting holes are generally machined using a bench drill press. In actual production, operators use special fixtures to firmly fix the advance advance cover to the drill press table. Because the mounting holes are arranged in a circular array on the edge of the cover, the position of the clamping device must be adjusted multiple times during drilling: after each hole is machined, the clamp must be released, the workpiece rotated to the next predetermined angle position, and then re-clamped. This process is repeated until all holes are machined, making it relatively cumbersome and time-consuming. To address this, a drilling and positioning device for machining the advance advance cover is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a drilling and positioning device for processing advance cover, so as to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling and positioning device for processing an advance cover, comprising a base, a connecting through hole at the edge of the base, a pedestal fixedly mounted on the base, a turntable rotatably mounted on the pedestal, an adjustment mechanism mounted on the pedestal, the adjustment mechanism comprising a drive shaft rotatably mounted within the pedestal, the upper end of the drive shaft fixedly mounted on the bottom of the turntable, a worm gear fixedly mounted on the drive shaft, one side of the worm gear rotatably mounted on a worm, the end of the worm fixedly mounted on a first knob, and a positioning mechanism mounted on the turntable.

[0018] 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.

[0019] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a drilling and positioning device for processing advance cover, including a base 1, a connecting through hole 2 at the edge of the base 1, a base 4 fixedly installed on the base 1, a turntable 3 rotatably installed on the base 4, an adjustment mechanism 5 installed on the base 4, and a positioning mechanism 6 installed on the turntable 3.

[0020] Specifically, the entire device is fixed to the bench drill by bolts and base 1, and the guide hole 602 is aligned vertically with the drill rod on the bench drill. Through the coordinated use of adjustment mechanism 5 and positioning mechanism 6, the advance mechanism cover connected to the upper end of turntable 3 can be rotated smoothly and steadily, so as to quickly open multiple mounting holes on the edge of the advance mechanism cover.

[0021] Example 2: Figure 2 and Figure 3As shown, the adjustment mechanism 5 includes a drive shaft 507 rotatably mounted in the base 4, with the upper end of the drive shaft 507 fixedly mounted on the bottom of the turntable 3. A worm gear 506 is fixedly mounted on the drive shaft 507, and one side of the worm gear 506 is rotatably mounted on a worm 504. The end of the worm 504 is fixedly mounted on a first knob 505. A rotating ring seat 501 is fixedly mounted on the upper end of the base 4. The upper end of the drive shaft 507 is fixedly mounted on a connecting plate 502. A connecting hole 503 is provided on the connecting plate 502, and a bolt is provided in the connecting hole 503. The connecting plate 502 is fixedly mounted on the bottom of the turntable 3 by bolts.

[0022] Specifically, the user can rotate the first knob 505, which will drive the worm gear 504 to rotate, the worm gear 504 to rotate, the worm wheel 506 to rotate, the worm wheel 506 to rotate, the drive shaft 507 to rotate, and the drive shaft 507 to rotate, which will drive the advance cover at the top of the turntable 3 to rotate, so as to quickly open multiple mounting holes on the edge of the advance cover.

[0023] Example 3: Figure 2 and Figure 4 As shown, the positioning mechanism 6 includes a threaded screw 604 and a movable shaft 608 rotatably mounted in the turntable 3, with the threaded screw 604 and the movable shaft 608 perpendicular to each other. A bevel gear 606 is fixedly mounted on the threaded screw 604. One end of the movable shaft 608 is fixedly mounted on a bevel gear 607, and the other end of the movable shaft 608 is fixedly mounted on a second knob 609. A screw nut 605 is threaded onto the threaded screw 604, and a linkage frame 603 is fixedly mounted on the screw nut 605. A pressure ring 601 is fixedly mounted on the upper end of the linkage frame 603, and a guide hole 602 is provided on the pressure ring 601. Slide grooves are provided on both sides of the turntable 3, and the linkage frame 603 is slidably mounted on the turntable 3 through the slide grooves. A rotation groove is provided inside the turntable 3, and the movable shaft 608 is rotatably mounted inside the turntable 3 through the rotation groove.

[0024] Specifically, after rotating the second knob 609, the movable shaft 608 will drive the bevel gear 607 at its end to rotate. The rotation of the bevel gear 607 will drive the bevel gear disc 606 to rotate. The rotation of the bevel gear disc 606 will then drive the threaded screw 604 to rotate. The rotation of the threaded screw 604 will cause the screw nut 605 to move downwards. After the screw nut 605 moves downwards, it will cause the pressure ring 601 at the upper end of the linkage frame 603 to move downwards. As the pressure ring 601 continuously applies downward pressure, the advance mechanism cover is firmly pressed against the upper working plane of the turntable 3. This pressing action ensures that the advance mechanism cover remains stable and does not shift throughout the drilling operation, providing a reliable positioning reference for subsequent drilling processes.

[0025] Working principle: The entire device is fixed to the bench drill by bolts and base 1, aligning the guide hole 602 with the drill rod on the drill. In use, the advance mechanism cover is placed on the top of the turntable 3. After placement, the second knob 609 is turned. Turning the knob causes the movable shaft 608 to rotate, which in turn rotates the bevel gear 607 at its end. This rotation then drives the bevel gear disc 606, which in turn rotates the threaded screw 604. The threaded screw 604 then moves the screw nut 605 downwards, which in turn moves the pressure ring 601 at the top of the linkage frame 603 downwards, thus tightening the advance mechanism cover and fixing it to the top of the turntable 3. This facilitates drilling operations. Furthermore, the user can rotate the first knob 505, which will drive the worm gear 504 to rotate. After the worm gear 504 rotates, it will drive the worm wheel 506 to rotate. After the worm wheel 506 rotates, it will drive the drive shaft 507 to rotate. After the drive shaft 507 rotates, it will drive the advance cover at the top of the turntable 3 to rotate, so as to quickly open multiple mounting holes on the edge of the advance cover.
