Abstract
Description
Technical Field
[0001] This utility model proposes a flipping device for lock testing, which belongs to the field of precision lock testing devices. Background Technology
[0002] In the lock manufacturing process, multi-face inspection of locks is a key step in ensuring product quality. Traditional lock flipping inspection methods mainly rely on manual operation or simple mechanical structures. However, traditional flipping methods are prone to detachment and it is difficult to ensure the consistency of the angle after flipping, resulting in fluctuations in inspection results. This is especially true in mass production, where it cannot meet the demand for efficient inspection. In addition, existing flipping devices mostly use fixed clamps, which are difficult to adapt to the differences in the shape of different lock models. Furthermore, workpieces are prone to loosening or shifting after flipping, affecting the accuracy of subsequent inspections. Moreover, traditional flipping equipment has poor integration with the production line, requiring manual loading and unloading or frequent parameter adjustments, which cannot achieve a fully automated lock inspection process and limits inspection efficiency.

[0004] The flipping device includes a testing platform, a turntable, and a flipping assembly mounted on the testing platform. The testing platform has a pre-drilled mounting hole, and the flipping assembly has a connecting hole for fixing. The flipping assembly includes a lifting part and a rotating part fixed by a connecting plate. The end of the rotating part is connected to a mechanical gripper. The head end of the mechanical gripper is detachably connected to the rod. The inner side of the gripper head end fits into the outer contour of the lock to be tested.
[0005] Preferably, the turntable includes a fixed inner plate and a movable outer plate. The movable outer plate is provided with a detection station, and a detection fixture is installed at the detection station. The flipping component is aligned with the detection station position on the turntable.
[0006] Preferably, the lifting unit includes a base fixed on the testing table. The base is connected to a fixing plate by a right-angle reinforcing member. A lifting cylinder is fixed on one side of the fixing plate, and two rows of fixed sliders are provided on the other side. A limiter matching the end of the cylinder is provided in the middle of the slider.
[0007] Preferably, the connecting plate is provided with a slide rail that matches the slider, and the connecting plate is provided with a long groove for the limiter to move.
[0008] Preferably, the fixing plate is provided with a cylinder end clamp on one side of the lifting cylinder.
[0009] Preferably, the top of the connecting plate has a connecting hole that matches the rotating part.
[0010] Preferably, the rotating part includes a cylinder seat fixedly connected to a connecting plate via a connecting column, a rotary cylinder fixedly connected to the outside of the cylinder seat, a coupling connected to the rotary cylinder through the cylinder seat, a connecting shaft connected to one end of the coupling, a bearing with a seat fixed in a connecting hole through a flange, and a clamping device connected to the other end of the connecting shaft.

[0014] The beneficial effects of this utility model are as follows:
[0015] This invention effectively solves the problems of precision, efficiency, adaptability, and maintenance cost in the traditional lock flipping process. Specifically, the combination design of a rotary cylinder and coupling, along with precise adjustment of the limit bolts, reduces the angle error during the 180° flipping of the lock. The mechanical gripper head adopts a detachable design that fits into the outer contour of the lock, allowing for compatibility with various lock models by changing the gripper head. This enables precise gripping of the lock under test, achieving accurate flipping and positioning. The adjustable design of the limit bolts extends the service life of the limit blocks, reducing the frequency of component replacement due to frequent collisions. Simultaneously, the modular design reduces the use of non-standard parts, shortens replacement time, and lowers equipment maintenance costs.
[0016] The lifting unit adopts a slider rail structure and cylinder end clamp for double limiting, which effectively suppresses shaking during the lifting process and reduces the positional deviation of the lock before and after flipping. The combination design of the seated bearing and connecting shaft enhances the rigidity of the rotating part. Combined with the support structure of the fixed baffle and L-shaped connecting block, it ensures no vibration during high-speed flipping and improves the stability and reliability of the flipping process.
[0017] The detachable gripper head and modular structure design reduce the adjustment time for different lock models. The alignment design between the flipping component and the turntable inspection station, combined with the horizontal adjustment axis of the fixed adjustment device, shortens the equipment installation and debugging time, improves the controllable accuracy of debugging, and enhances product testing efficiency.

A clamping device 34 is connected to the other end of the connecting shaft. The connecting shaft passes through a seated bearing 321. The seated bearing 321 is fixed to the connecting hole 318 via a flange.
[0044] The coupling 322 has a groove, in which a limiting protrusion 325 is fixed. The cylinder seats 323 located at both ends of the coupling 322 are also provided with limiting blocks 326.

A fixed baffle 329 is provided on the outside of the gripper cylinder 334 and the connecting shaft to prevent horizontal displacement of the gripper cylinder 334 and the connecting shaft. An L-shaped connecting block 330 is fixed to the bottom of the connecting shaft by bolts. A linear slide rail is installed on the L-shaped connecting block. A pair of sliders are provided on the slide rail. The moving arm of the gripper cylinder is connected to the mechanical gripper 331 through a right-angle block 332. The lower end of the mechanical gripper 331 is fixed on the slider. The mechanical gripper 331 is connected to the guide rail through the slider to form a rigid sliding pair. The head end of the mechanical gripper 331 adopts a detachable design and is connected to the rod by an internal hex bolt. The inner side of the head end is matched with an appropriate fitting block according to the shape of the lock.
