Description

Technical Field

[0001] This utility model relates to the field of key processing technology, specifically a car key head forming and feeding device. Background Technology

[0002] A car key cylinder typically refers to the mechanical part of a key that is inserted into a vehicle's lock cylinder or ignition switch. Its core function is to mechanically unlock the car or start the engine through physical structures (such as toothed designs). For traditional keys, the key cylinder is a crucial component that directly engages with the vehicle's mechanical lock cylinder. Some modern keys also integrate electronic chips, such as magnetic chip systems, into their key cylinders for communication with the vehicle's anti-theft system.

[0003] When forming car key tips, the key tip needs to be inserted into the processing equipment to process the tooth shape. Traditional car key forming feeding structures only limit the key tip by clamping it and then insert it into the equipment by moving it. This feeding method cannot accurately position the key tip, which can easily cause positional deviations when processing the tooth shape. At the same time, the upper and lower clamps cannot completely fix the key tip, and the key tip is prone to wobbling from side to side at the clamping part during processing. Utility Model Content

[0004] The purpose of this utility model is to provide a key head forming feeding device. By moving the movable frame downward, the key head blank is clamped by the upper and lower conveying rollers. Then, the position of the key head blank is calibrated from both sides by limiting blocks, and clamped and fixed at the same time, thereby ensuring the stability of the key head blank during processing and improving the processing accuracy, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car key tip forming and feeding device, comprising: Fixed frame and moving frame; Both the fixed frame and the movable frame are rotatably connected by bearings to two sets of conveying rollers. Limiting blocks are slidably arranged on both sides of the inner cavity of the fixed frame and the movable frame. The opposite side of the limiting blocks extends outward to the outside of the fixed frame and the movable frame to position and clamp the key head blank, preventing the key head blank from shifting during the feeding process. It also includes a clamping component that moves the limiting blocks in opposite directions, so that the limiting blocks move synchronously towards the center and restrict the key head blank in the middle position; The fixed frame is fixedly installed inside the box, and the movable frame is located above the fixed frame and is movably disposed inside the box.

[0017] 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.

[0018] This utility model provides, for example Figures 1-6 The illustrated car key tip forming and feeding device includes: Fixed frame 1 and movable frame 2; Two sets of conveying rollers 3 are rotatably connected to the fixed frame 1 and the movable frame 2 through bearings. Limiting blocks 4 are slidably arranged on both sides of the inner cavity of the fixed frame 1 and the movable frame 2. The opposite side of the limiting block 4 extends outward to the outside of the fixed frame 1 and the movable frame 2 to position and clamp the key head blank, preventing the key head blank from shifting during the feeding process. It also includes a clamping component 5 that moves the limiting block 4 in opposite directions, so that the limiting block 4 moves synchronously towards the middle, thus restricting the key head blank to the middle position. The fixed frame 1 is fixedly installed inside the box 6, and the movable frame 2 is located on the upper side of the fixed frame 1 and is movably installed inside the box 6. Feeding ports 7 are opened at the front and rear ends of the box 6. By installing the housing 6 at the feed inlet of the key head processing equipment, the internally installed optical grating sensor detects the insertion of an object into the feed port 7. Subsequently, the electric push rod 8 in the movable frame 2 is driven to press down, and the key head blank is clamped by the upper and lower conveying rollers 3. Then, the clamping assembly 5 drives the two sets of limit blocks 4 to move towards the middle, moving the key head blank to the middle position of the feed port 7 and clamping and fixing it from left and right. This ensures the stability of the key head blank during processing and avoids shaking that would reduce processing accuracy.

[0019] Among them, such as Figure 3-4 As shown: The clamping assembly 5 includes a first drive motor 51 fixed to the bottom of the inner cavity of the housing 6. The output shaft of the first drive motor 51 is fixed with a bidirectional screw 52. One end of the bidirectional screw 52 away from the first drive motor 51 is rotatably connected to the other side of the inner cavity of the housing 6 through a bearing. Movable blocks 53 are threaded to both sides of the bidirectional screw 52. Limiting grooves 54 are opened on both sides of the bottom of the fixed frame 1. A moving rod 55 is fixed to the top of the movable block 53. The moving rod 55 moves upward and passes through the limiting blocks 4 on the fixed frame 1 and the movable frame 2 in sequence. The first drive motor 51 drives the bidirectional screw 52 to rotate, so that the bidirectional screw 52 drives the two sets of movable blocks 53 in opposite directions, so that the movable blocks 53 move the two sets of limiting blocks 4 through the moving rod 55. When the limiting blocks 4 move towards the middle, they can not only adjust the position of the inserted key blank, but also clamp the key blank. At the same time, the limiting blocks 4 are slidably set on the moving rod 55, which can ensure that the upper limiting blocks 4 can be moved by the moving rod 55 after moving up and down.

[0020] Furthermore, such as Figure 3 As shown: An electric push rod 8 is fixed at the top of the inner cavity of the movable frame 2. The piston rod of the electric push rod 8 passes through the movable frame 2 and is fixedly connected to the upper end face of the inner cavity of the box 6. The height of the movable frame 2 is adjusted by the electric push rod 8, and the position of the upper conveying roller 3 is moved by the movable frame 2, so as to realize the clamping of the key head blank by the conveying roller 3.

[0021] Preferred, such as Figure 5 As shown: It also includes a drive assembly 9 for driving the conveyor rollers 3. The drive assembly 9 includes a second drive motor 91 fixed on the inner side wall of the fixed frame 1. The output shaft of the second drive motor 91 is fixed with a drive synchronous wheel 92. Two sets of conveyor rollers 3 inside the fixed frame 1 are fixed with driven synchronous wheels 93. The outer sides of the drive synchronous wheel 92 and the driven synchronous wheel 93 are connected by a synchronous belt 94. The second drive motor 91 drives the drive synchronous wheel 92 to rotate. Then, the synchronous belt 94 drives the two sets of driven synchronous wheels 93 and the conveyor rollers 3 to rotate synchronously and in the same direction, which facilitates feeding and unloading of the key head blank.

[0022] It is worth noting that, such as Figure 6 As shown: It also includes a T-shaped limiting frame 10 located inside the movable frame 2, which is used to limit the key head blank before the movable frame 2 is pressed down. A limiting frame 11 is fixed on the upper end surface of the inner cavity of the movable frame 2. The top of the T-shaped limiting frame 10 extends into the limiting frame 11 and is fixed with a support spring 12. The top of the support spring 12 is fixed on the upper end surface of the inner cavity of the limiting frame 11. Through the elastic limitation of the T-shaped limiting frame 10, the key head blank is initially limited before the upper conveyor roller 3 is pressed down, preventing the key head blank from slipping into the processing equipment due to unstable center of gravity.

[0023] In a further preferred embodiment, such as Figure 6 As shown: The T-shaped limiting frame 10 has two sets of sliding grooves 13. The moving rod 55 is located in the sliding groove 13. The bottom of the limiting block 4 below the movable frame 2 has a storage groove 14 for storing the T-shaped limiting frame 10. The sliding groove 13 on the T-shaped limiting frame 10 facilitates the movement of the moving rod 55 under the action of the movable block 53. The moving rod 55 slides in the sliding groove 13 without affecting the use of the T-shaped limiting frame 10. Then, the storage groove 14 is opened at the bottom of the limiting block 4. After the movable frame 2 moves down, it drives the upper conveying roller 3 to contact the key head blank, preventing the T-shaped limiting frame 10 from being placed between the key head blank and the conveying roller 3.

[0024] In addition, such as Figure 6 As shown: A curved chamfer is provided on one side of the bottom of the T-shaped limit frame 10, and the curved chamfer is located at the end of the T-shaped limit frame 10 near the key head blank insertion feeding port 7. The curved chamfer helps to prevent the key head blank from colliding with the T-shaped limit frame 10 when the key head blank is inserted. The curved chamfer can guide and misalign the key head blank.

[0025] In this embodiment, as Figure 2 As shown: Two sets of limiting rods 15 are vertically fixed on both sides of the inner cavity of the box 6. The movable frame 2 is slidably set on the outside of the limiting rods 15. By setting the limiting rods 15, the stability of the movable frame 2 in the box 6 is limited, and the movable frame 2 is prevented from shaking during the up and down movement.

[0026] It is worth noting that sensors are also installed inside the housing 6, such as grating sensors for detecting whether the key head blank is inserted. The grating sensors are installed on both sides of the inner cavity of the housing 6, located between the fixed frame 1 and the movable frame 2. Pressure sensors are also included to detect the contact between the conveying roller 3 and the limiting block 4 and the key head blank. The control unit of the device adopts a PLC controller, and the operation process is carried out by the pre-programmed molding.

[0027] In practical use, the key head blank to be processed is inserted into the feed port 7. The grating sensor detects the key head blank, and then the electric push rod 8 is activated. The electric push rod 8 drives the movable frame 2 to move down, so that the upper conveying roller 3 and the lower conveying roller 3 initially clamp the key head blank. Before the movable frame 2 moves down, the T-shaped limit frame 10 limits the key head blank under the support of the support spring 12. With the help of the lower conveying roller 3, the key head blank can be kept stable. Then, the second drive motor 91 drives the bidirectional screw 52 to rotate. The bidirectional screw 52 drives the movable block 53 to move to the middle. Then, the limit block 4 moves to the middle under the drive of the moving rod 55 to move the key head blank that is not in the middle position. Then, it is clamped and limited. Then, the first drive motor 51 drives the drive synchronous wheel 92 to rotate. The drive synchronous wheel 92 drives the driven synchronous wheel 93 and the conveying roller 3 in the fixed frame 1 to rotate through the synchronous belt 94, transferring the key head blank inward.
