Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, specifically, it relates to an automotive engine bracket drilling jig flipping device. Background Technology

[0002] In the process of automobile production and processing, the engine mount is a major working component. During the processing of the engine mount, holes need to be drilled in different parts to install different parts. Most factories use radial drilling machines to drill holes. When drilling, the engine mount needs to be clamped by a drill jig and restricted during drilling.

[0003] A document with publication number (CN217166629U) discloses a universal rotating drill jig for transmission frames, including a base frame, a rotating frame, a sliding plate, and a connecting frame. Two base frames are connected to rollers via connecting plates. The rotating frame is connected to rotating rollers via fixed plates, and the rotating rollers are inserted into the rollers. Two second inserts are fixed below the fixed plate on one side of the rotating frame, and second inserts are also fixed on the rotating frames on both sides. The connecting plate is movably connected to a rod via a first insert. One end of the rod is inserted into the first insert and then into the corresponding second insert. The connecting frame is connected to the rotating frame via a side plate. The sliding plate is movably connected to the rotating frame via a clamping plate. This invention solves the problems of existing rotating drill jigs for transmission frames being unable to perform multi-face drilling and being unsuitable for various transmission frames. The above device can perform multi-face drilling after a single installation and is suitable for drilling various transmission frames.

[0004] In actual use, the aforementioned device has an issue with adjusting the slide plate. By directly engaging and sliding the slide plate, the position adjustment of the slide plate becomes unstable. During adjustment, it is impossible to accurately position the slide plate in the corresponding position, causing it to move within the drill jig and affecting the drilling.

[0005] In view of this, this utility model is proposed. Utility Model Content

The drilling jig assembly includes a mounting frame, a mounting frame, a mounting block, and a drilling jig cylinder. The mounting frame is fixedly connected to the mounting frame, and the mounting block is slidably connected to the mounting frame. The drilling jig cylinders are symmetrically arranged on the mounting blocks, and each drilling jig cylinder is engaged with the mounting block by other components.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] Please see Figure 1-5 A drilling jig flipping device for an automobile engine bracket includes a drilling jig assembly for drilling the bracket. The drilling jig assembly includes a mounting frame 1, a mounting frame 2, a mounting block 3, and a drilling jig cylinder 5. The mounting frame 2 is fixedly connected to the mounting frame 1, and the mounting block 3 is slidably connected to the mounting frame 2. The drilling jig cylinders 5 are symmetrically arranged on the mounting blocks 3, and each drilling jig cylinder 5 is engaged with the mounting block 3 through other components. Through the mutual cooperation of the internal components of the drilling jig assembly, the position of the drilling jig cylinder 5 can be adjusted. The movable block 4 can achieve self-locking to prevent the position of the drilling jig cylinder 5 from moving arbitrarily during the adjustment of the drilling jig cylinder 5 and affecting the drilling.

[0028] The mounting block 3 has symmetrically arranged grooves, and each groove has a movable block 4 slidably connected to it. Each movable block 4 is fixedly connected to the corresponding drill jig cylinder 5. The mounting block 3 has symmetrically arranged racks 41, each rack 41 is fixedly connected to the mounting block 3, and each movable block 4 has a toothed block 44 elastically connected to it. Each toothed block 44 meshes with the rack 41. Each movable block 4 has a sliding rod 42 slidably connected to it, each sliding rod 42 is fixedly connected to the corresponding toothed block 44, and each sliding rod 42 is fitted with a spring 43. The end of each spring 43 is fixedly connected to the corresponding movable block 4 and toothed block 44. When the operator applies force inward to the movable block 4, since the meshing direction of the toothed block 44 and the rack 41 is designed to be towards the central axis of the mounting block 3, this direction of movement is not constrained by the mechanism, and the displacement of the movable block 4 will synchronously drive the drill jig cylinder 5 to adjust its position. When external adjustment is required, the operator must first pull the slide bar 42 outward. At this time, the toothed block 44 and the rack 41 are disengaged. Then, the movable block 4 is pushed to move the drill jig cylinder 5 outward for positioning. After moving to the target position, the displacement of the slide bar 42 will compress the spring 43, causing it to undergo elastic deformation and react on the toothed block 44, prompting the toothed block 44 and the rack 41 to re-engage and lock. This self-locking mechanism effectively ensures the positioning stability of the drill jig cylinder 5, avoids displacement deviation caused by equipment vibration or external force interference during processing, and ensures the positional accuracy of drilling operations. The mechanism design specifically adopts the matching calculation of spring preload and tooth profile angle, so that the meshing torque is always greater than the drilling reaction torque, thereby achieving a reliable position holding function.

[0029] Each movable block 4 is connected to a threaded rod 45 by a thread. The end of each threaded rod 45 is in close contact with the wall surface of the mounting block 3. When the threaded rod 45 is rotated manually, it is brought into close contact with the mounting block 3, thereby restricting the position between the movable block 4 and the mounting block 3. This restricts the position of the movable block 4 during inward movement and prevents the movable block 4 from moving arbitrarily during inward adjustment.

[0030] The mounting frame 2 is fixedly connected to a drive motor 22, and the output end of the drive motor 22 is fixedly connected to a lead screw 21. The lead screw 21 is threadedly connected to a sliding block 23, and the sliding block 23 is fixedly connected to the mounting block 3. The drive motor 22 drives the lead screw 21 to rotate through the output end, and the lead screw 21 drives the sliding block 23 to move through the thread. The position of the mounting block 3 is changed during the movement of the sliding block 23, and the lateral position is precisely changed through the thread drive of the lead screw 21.

[0031] Working principle: When the operator applies inward force to the movable block 4, since the meshing direction of the toothed block 44 and the rack 41 is designed towards the central axis of the mounting block 3, this direction of movement is not constrained by the mechanism. The displacement of the movable block 4 will synchronously drive the drill jig cylinder 5 to adjust its position. When outward adjustment is required, the operator must first pull the slide rod 42 outward. At this time, the toothed block 44 and the rack 41 are disengaged, and then the movable block 4 is pushed to drive the drill jig cylinder 5 to move outward for positioning. When it moves to the target position, the displacement of the slide rod 42 will compress the spring 43, causing it to undergo elastic deformation and react on the toothed block 44, prompting the toothed block 44 and the rack 41 to re-engage and lock. This self-locking mechanism effectively ensures the positioning stability of the drill jig cylinder 5, avoids displacement deviation caused by equipment vibration or external force interference during processing, and ensures the positional accuracy of drilling operations. The mechanism design specifically adopts the matching calculation of spring preload and tooth profile angle, so that the meshing torque is always greater than the drilling reaction torque, thereby achieving a reliable position holding function. After manually rotating the threaded rod 45 and making it tightly contact the mounting block 3, the position between the movable block 4 and the mounting block 3 is restricted, thereby restricting the position of the movable block 4 during inward movement and preventing the movable block 4 from moving arbitrarily during inward adjustment. The drive motor 22 drives the lead screw 21 to rotate through the output end, and the lead screw 21 drives the sliding block 23 to move through the thread. The movement of the sliding block 23 changes the position of the mounting block 3, and the thread drive of the lead screw 21 achieves precise change of lateral position.
