[0002] At present, most of the through-hole processes of lock core components are manual operations, with low mechanization degree, high requirements for human resources, and great subjectivity in manual operations. For different employees, the qualified rates of the processed lock cores are different, so the qualified rate of lock core processing cannot be well controlled. There are also some existing through-hole processing devices. For example, the utility model CN212469412U discloses a punching device for lock core production that is easy to fix, including a base. A rotary table bearing is fixedly embedded at the upper end of the base, a rotating disk is fixedly connected to the upper end of the rotary table bearing, a clamping block is arranged at the upper end of the rotating disk, a support frame is fixedly welded at the lower end of the base, a motor is arranged at the upper end of the support frame, and one end of the output shaft of the motor penetrates through the base and is fixedly connected to the lower surface of the rotating disk. An L-shaped column is fixedly welded on one side of the upper end of the base, and a hydraulic cylinder is fixedly installed at the upper end of the L-shaped column through a fixing frame. The utility model can drive the rotating disk to rotate through the motor, so that the clamping block rotates to the directly below of the punching knife for slot punching. And at the same time of punching, the lock core to be punched can be installed in another clamping block for punching, which saves the time of material taking and loading to a certain extent and improves the production efficiency. However, this punching device can only perform through-holes on one product at a time, with low punching efficiency, unable to process multiple parts at one time, and low automation degree. Summary of the Utility Model

[0003] The utility model discloses a lock core through-hole device, aiming to improve the problems of low production efficiency of the existing lock core through-hole device and poor stability of the turntable during through-holes.

[0004] The utility model adopts the following scheme:

[0005] A lock core through-hole device, comprising: a rotating platform, on which a pressing mechanism, a robot feeding mechanism and a plurality of fixture platforms are arranged, and the rotating platform is adapted to drive the fixture platforms to switch between a loading station, a through-hole station and a discharging station by rotation; wherein, the fixture platform includes a fixture plate adapted to mount at least two workpieces, a plurality of guide rods and elastic buffer members are arranged below the fixture plate, and a through-hole thimble assembly corresponding to each workpiece is arranged below the fixture plate; the pressing mechanism is arranged above the through-hole station to press the workpiece down when the fixture platform moves to directly below it, so that the through-hole thimble assembly performs through-hole on the workpiece from bottom to top; the robot feeding mechanism is arranged at the discharging station to discharge the workpieces that have completed through-holes; a supporting universal wheel corresponding to the through-hole thimble assembly is arranged on the bottom surface of the rotating platform directly below the pressing mechanism to support the rotating platform when the pressing mechanism presses down.

[0006] Further, the supporting universal wheel is in rolling friction with the bottom surface of the rotating platform, and one supporting universal wheel is correspondingly arranged for each group of through-hole thimble assemblies.

[0007] Further, two card slots adapted to place fixtures are arranged on the fixture plate, a thimble hole adapted to allow the through-hole thimble assembly to pass through is arranged on the fixture, and two pin holes are arranged on both sides of the fixture for easy fixing.

[0008] Further, the elastic buffer member includes two groups of through rods penetrating through the fixture plate and springs sleeved outside the through rods, and the springs are arranged between the fixture plate and the bottom plate to provide an elastic buffering effect for the fixture plate when the pressing mechanism drives the workpiece to descend and drives the fixture plate to descend.

[0009] Further, the through-hole thimble assembly includes a plurality of thimbles, and the thimbles are adapted to pass through the thimble holes to perform through-hole on the workpiece from bottom to top when the pressing mechanism drives the workpiece to descend.

[0010] Further, the pressing mechanism includes a pressing cylinder and a pressing block connected to the extending rod of the pressing cylinder, and the pressing block is adapted to act on two workpieces simultaneously to press the two workpieces down simultaneously.

[0011] Further, an avoidance hole is arranged on the pressing block for avoiding the thimbles ejected from the workpiece.

[0014] Furthermore, detection sensors are provided at the loading station, the through-hole station, and the unloading station to detect whether a workpiece is placed on the fixture plate.

[0015] Beneficial effects:

[0016] In this solution, the rotary platform rotates to drive the fixture platform to flow between the loading station, the through-hole station, and the unloading station. Each time, at least two lock core workpieces can be drilled with through-holes, realizing through-hole automation and improving the through-hole efficiency. The through-hole is drilled from the bottom up. By placing the workpiece in the fixture and driving the workpiece to move by pressing down the top block, on the one hand, the top block pressing on the workpiece can fix the workpiece to prevent the workpiece from shifting. On the other hand, the workpiece and the ejector pin can be in contact before the through-hole, so that the impact force of the ejector pin on the workpiece during the through-hole is small, which can prevent the workpiece from deforming due to force on other parts. In addition, support universal wheels are provided at the bottom of the rotary platform. The support universal wheels are arranged at the through-hole station and are located at the bottom of the pressing mechanism. When the pressing mechanism descends and the through-hole ejector pin assembly performs through-hole drilling, the support universal wheels support the bottom of the through-hole ejector pin assembly, which can effectively prevent the local pressure impact on the rotary platform during the through-hole process from causing the rotary platform to tilt, thereby affecting the through-hole quality. The support universal wheels are in contact with the bottom surface of the rotary platform through rolling friction. On the one hand, it does not affect the rotation of the rotary platform, and on the other hand, it is also beneficial to the stability of the rotary platform. Description of the drawings

[0023] Combined with Figures 1 to 5 As shown, this embodiment provides a lock core through-hole device, including: a rotating platform 1, on which a pressing mechanism 2, a robot unloading mechanism 3 and a number of fixture platforms 4 are arranged. The rotating platform 1 is adapted to drive the fixture platform 4 to switch between the loading station, the through-hole station and the unloading station by rotation; wherein, the fixture platform 4 includes a fixture plate 41 adapted to install at least two workpieces. A number of guide rods 44 and elastic buffers 45 are arranged below the fixture plate 41, and a through-hole thimble assembly 43 corresponding to the workpiece one by one is arranged below the fixture plate 41; the pressing mechanism 2 is arranged above the through-hole station to press the workpiece down when the fixture platform 4 moves to directly below it, so that the through-hole thimble assembly 43 performs through-holing on the workpiece from bottom to top; the robot unloading mechanism 3 is arranged at the unloading station to unload the workpiece that has completed the through-holing; a support universal wheel 6 corresponding to the through-hole thimble assembly 43 is arranged on the bottom surface of the rotating platform 1 directly below the pressing mechanism 2 to support the rotating platform 1 when the pressing mechanism 2 presses down.

[0024] Combined with Figures 1 to 3As shown, in this embodiment, the rotating platform 1 adopts a turntable mechanism, and a servo motor is connected to the bottom of the turntable to drive the turntable to rotate. Three fixture platforms 4 are arranged on the turntable. Thus, each time it rotates, there is a fixture platform 4 at the loading station, the through-hole station, and the unloading station. The fixture platform 4 loads materials at the loading station, makes through-holes at the through-hole station, and unloads materials at the unloading station. Through the turntable, the fixture platform 4 can circulate among the three stations to achieve automated operation. The supporting universal wheels 6 are in rolling friction with the bottom surface of the rotating platform 1, and one supporting universal wheel 6 is correspondingly arranged for each group of through-hole thimble assemblies 43. Here, the supporting universal wheels 6 are arranged at the through-hole station and are located at the bottom of the pressing mechanism 2. When the pressing mechanism 2 descends and the through-hole thimble assembly 43 makes a through-hole during the through-hole process, the supporting universal wheels 6 support the bottom of the through-hole thimble assembly 43, which can effectively prevent the rotating platform 1 from being damaged due to the local pressure effect during the through-hole process. Moreover, the supporting universal wheels 6 are in contact with the bottom surface of the rotating platform 1 in a rolling friction manner. On the one hand, it does not affect the rotation of the rotating platform 1, and on the other hand, it is also beneficial to the stability of the rotating platform 1. In this embodiment, through the local support method, only the through-hole station is supported, which can save equipment costs and simplify the equipment structure.

[0025] Combined with Figures 1 to 5 As shown, the fixture platform 4 includes a fixture plate 41 and a bottom plate 42. A guide rod 44 is arranged between the fixture plate 41 and the bottom plate 42 for guiding, and an elastic buffer 45 is arranged between the bottom plate 42 and the fixture plate 41. The elastic buffer 45 includes two through rods passing through the fixture plate 41 and springs sleeved outside the through rods. The springs are arranged between the fixture plate 41 and the bottom plate 42 to provide an elastic buffering effect for the fixture plate 41 when the pressing mechanism 2 drives the workpiece to descend and drives the fixture plate 41 to descend. Here, the elastic buffer 45 is arranged on the opposite sides of the fixture plate 41 to prevent the workpiece from being damaged due to excessive pressing stroke, and at the same time, it can drive the fixture plate 41 to rise to the initial position after the through-hole pressing is completed. Two slots suitable for placing the fixture 46 are arranged on the fixture plate 41. The fixture 46 is provided with a thimble hole suitable for the through-hole thimble assembly 43 to pass through, and two pin holes 462 are arranged on both sides of the fixture 46 for easy fixing. During loading, first fix the fixture 46 in the slot, and then place the workpiece in the fixture 46. It should be noted that the fixture 46 can be replaced when it is damaged or can be replaced according to different workpieces.

[0026] The through-hole ejector pin assembly 43 includes a number of ejector pins, which are adapted to pass through the ejector pin holes from bottom to top to perform through-holes on the workpiece when the pressing mechanism 2 drives the workpiece to descend. Here, the through-hole ejector pin assembly 43 is installed on the bottom plate 42, and its top is located in the ejector pin hole of the fixture 46; the through-hole ejector pin assembly 43 can be replaced as needed, for example, replacing ejector pins with different lengths, different shapes, and different quantities to meet different through-hole requirements.

[0027] Combined with Figure 4 As shown, the pressing mechanism 2 includes a pressing cylinder 21 and a pressing block 22 connected to the extending rod of the pressing cylinder 21. The pressing block 22 is adapted to act on two workpieces simultaneously to press the two workpieces down at the same time. The extending stroke of the pressing cylinder 21 is adjustable to meet different through-hole requirements. Preferably, an avoidance hole 221 is provided on the pressing block 22 to avoid the ejector pins ejected from the workpiece and prevent the ejector pins from being damaged by the pressing block 22.

[0028] Combined with Figure 1 As shown, the robotic unloading mechanism 3 includes a motion mechanism 31 and at least two jaw assemblies 32. The jaw assemblies 32 are adapted to grip the workpieces on the fixture plate 41 and place the workpieces into the unloading frame through the motion mechanism 31. The motion mechanism 31 can be a three-axis motion mechanism 31. The motion mechanism 31 and the jaw assemblies 32 can adopt existing mechanisms, which will not be elaborated here.

[0029] In a preferred embodiment, detection sensors 5 are provided at the loading station, the through-hole station, and the unloading station to detect whether there are workpieces placed on the fixture plate 41. Here, the detection sensors 5 can adopt infrared sensors to detect whether the loading is successful, etc.
