Description

Technical Field

[0001] This utility model relates to the field of car key processing, and in particular to a car key processing tray machine that facilitates mold replacement. Background Technology

[0002] As a core component of a car's security system, the manufacturing process of car keys involves multiple steps, including stamping, cutting, coding, and assembly. In mass production, automated feeding and precise placement of key blanks are crucial for improving processing efficiency and ensuring product quality. When processing the car key shell, it needs to be placed in a mold using a placement machine for easy processing.

[0003] A search of Chinese patents revealed an automatic key-opening machine with publication number CN217344654U, comprising an automatic key-opening machine's automatic tray-positioning mechanism. The mechanism includes a frame, an engraving machine, a feeding table, and a feeding tray. The frame has an engraving machine and an engraving platform arranged vertically on its outer side. A feeding table is located on the front side of the engraving platform, and its surface is equipped with feeding grippers for key gripping. A first slide rail is fixedly mounted on the side of the frame, and a first connecting frame is connected to the outer side of the first slide rail. A second slide rail is fixedly mounted to the outer side of the first connecting frame, and a telescopic cylinder is mounted at the top of the second slide rail. The end of the telescopic cylinder is connected to the second connecting frame, and the bottom outer side of the second connecting frame is equipped with tray-positioning grippers. This automatic key-opening machine's automatic tray-positioning mechanism facilitates key gripping in conjunction with the engraving and feeding mechanism, allowing for easy key placement and ensuring stable key retrieval.

[0004] Existing key slab machines are inconvenient for changing molds. They typically place car keys on key molds for slab arrangement, but the mold size is only suitable for one type of car key. For different types of car keys, the mold needs to be changed. Molds are usually fixed in place with a large number of bolts, which is troublesome to change, increases workload, and reduces efficiency. To solve the above problems, we propose a key slab machine for car key processing that allows for easy mold changing. Utility Model Content

A spring 12 is provided on the surface of the slide rod 7, and a pull rod 13 is bolted to the surface of the slide rod 7. By pulling the pull head 24, the pull head 24 moves and drives the pull rod 13 to move the slide rod 7. The movement of the slide rod 7 causes the snap-fit ​​connector 8 to disengage from the snap-fit ​​hole 9, allowing the key mold 5 to be removed and replaced. This method facilitates mold replacement, reduces workload, and improves replacement efficiency.

[0032] refer to Figure 1 The plate-swing mechanism 2 includes a fixed frame 16, a linear motor 17 is bolted to the surface of the fixed frame 16, a fixed plate 18 is bolted to the surface of the moving part of the linear motor 17, a lifting cylinder 19 is bolted to the top of the fixed plate 18, a double-headed synchronous cylinder 20 is bolted to the bottom of the lifting cylinder 19, and the double-headed synchronous cylinder 20 is slidably connected to the inner wall of the fixed plate 18. Both ends of the double-headed synchronous cylinder 20 are bolted with clamping heads 21. By setting up the plate-swing mechanism 2, it is convenient to place the key shell on the plate.

[0033] refer to Figure 1The moving mechanism 3 includes a support plate 22, which is bolted to the top of the operating table 1. An electric push rod 23 is bolted to the surface of the support plate 22, and the electric push rod 23 is bolted to the surface of the fixed base 4.

[0034] refer to Figure 3 One end of the card connector 8 is wedge-shaped, which facilitates the fixing of the key mold 5.

[0035] refer to Figure 1 , Figure 2 and Figure 3 One end of the pull rod 13 is bolted with a pull head 24, which facilitates the movement of the pull rod 13.

[0036] Example 2:

[0037] refer to Figure 1 and Figure 2 The inner wall of the slide rod 7 is slidably connected to the slide plate 14, and the two springs 12 are respectively bolted to the surfaces of the slide plate 14 and the slide rod 7. The inner wall of the slide plate 14 is connected to the surface of the pull rod 13. The surface of the slide plate 14 is rotatably connected to the adjusting bolt 15, and the inner wall of the adjusting bolt 15 fixing seat 4 is threaded. By loosening the fixing nut 25 and rotating the adjusting bolt 15, the adjusting bolt 15 rotates and drives the slide plate 14 to move. The movement of the slide plate 14 changes the elastic force of the spring 12, thereby adjusting the tension of the spring 12, thus ensuring the stability of the snap-fit ​​joint 8 and the snap-fit ​​hole 9.

[0038] refer to Figure 2 The adjusting bolt 15 has a threaded connection to a fixing nut 25. By setting the fixing nut 25, the adjusting bolt 15 is fixed, thereby improving stability.

[0040] Brief description of operation: This device is used in conjunction with a conveyor belt. The coordination of each component is controlled by a PLC controller. The conveyor belt transports the key shells to the loading point. Linear motor 17 moves the clamping head 21 to the key shell. Then, lifting cylinder 19 lowers the clamping head 21, and double-head synchronous cylinder 20 moves the clamping head 21 to clamp the key shell. Then, lifting cylinder 19 raises it, and linear motor 17 moves the key shell to the mold. The key shells are placed sequentially into the mold cavity, thus achieving the purpose of tray placement. Moving pull head 24 causes pull rod 13 to drive slide rod 7 to move, which in turn drives rack 10 to move. The movement of rack 10 drives gear 11 to rotate, and the rotation of gear 11 drives another rack 1... 0 drives another slide bar 7 to move, causing the two slide bars 7 to move in opposite directions. The movement of the slide bars 7 in opposite directions causes the snap-fit ​​connector 8 to move in opposite directions. The snap-fit ​​connector 8 disengages from the snap-fit ​​hole 9, allowing the key mold 5 to be removed. The mounting rod 6 on the required key mold 5 is then inserted into the fixing base 4. Under the action of the spring 12, the slide bar 7 drives the snap-fit ​​connector 8 to snap into the snap-fit ​​hole 9, fixing it in place and completing the replacement. This facilitates mold replacement. By loosening the fixing nut 25 and rotating the adjusting bolt 15, the adjusting bolt 15 rotates, causing the slide plate 14 to move. The movement of the slide plate 14 changes the elastic force of the spring 12, thereby adjusting the tension of the spring 12 and ensuring the stability of the snap-fit ​​connector 8 and the snap-fit ​​hole 9.
