Description

Technical Field

[0001] This invention relates to the field of key machines, and more specifically, to a horizontal key machine integrated fixture and its method of use. Background Technology

[0002] A horizontal key-making machine is a specialized device for processing keys. It features a horizontal design, typically with a robust body and a precise machining system. Its working principle involves a motor-driven cutting tool cutting and grinding the key blank to replicate or create a key that meets specific requirements. Horizontal key-making machines are designed with stability and precision in mind, capable of handling various types and complexities of keys, including common household keys and car keys. They are equipped with adjustable clamps to ensure the key blank remains in a stable position during processing. The user interface is usually simple and intuitive, facilitating parameter settings and operation control. Some high-end horizontal key-making machines also feature automation functions, such as automatic tool feed and automatic measurement, further improving processing efficiency and accuracy. In summary, the horizontal key-making machine, with its high efficiency, precision, and stability, has become an indispensable tool in the key processing industry.

[0003] The existing horizontal key cutting machine integrated fixture consists of a lower positioning block and an upper slider, fixed on a horizontally movable guide rail. It can clamp the key that needs to be cut open, bring it close to the cutting blade, and cut it into a new key. However, since it can only move horizontally in a straight line and cannot tilt, it cannot process keys with a certain angle in the tooth shape, resulting in poor performance.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a horizontal key machine integrated fixture and its usage method. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a horizontal key machine integrated fixture and its usage method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a horizontal key-making integrated fixture, comprising a base plate and clamps located on both sides of the top plate, one for clamping a cloned key and the other for clamping a key blank to be processed. Each clamp includes an upper clamping block and a lower clamping block, with a spring placed in the middle to control the rebound between the upper and lower clamping blocks. The horizontal key-making integrated fixture further includes: Angle switch: It includes an upper cover installed at the bottom of the lower clamping block, and a left base installed below the upper cover. The mating part of the two is provided with a diamond-shaped edge for changing the angle of the clamp. Clamping assembly: It is rotatably connected to the left base. By pressing down the upper clamping block, the distance between the upper and lower clamping blocks is brought closer, and pressure is also applied to the lower clamping block. Finally, the pressure is transmitted to the upper cover, which also presses the upper cover and the left base together. Thus, while controlling the tightness of the clamping blocks, the left and right angles of the clamp are also locked simultaneously.

[0007] Preferably, the surface of the upper cover is fixedly connected to a cover plate by M4 screws to prevent the corner bracket from loosening and falling off.

[0008] Preferably, the clamping assembly includes a screw that passes sequentially through the upper clamping block, the lower clamping block, and the upper cover into the left base. The spring is sleeved on the screw located between the upper and lower clamping blocks. The screw is fixed inside the left base by a D4 pin. The screw can rotate along the outer wall of the D4 pin. The head of the screw is threadedly connected to a locking wrench.

[0009] Preferably, a right base is fixedly connected to the right side of the left base, a support plate A is fixedly connected to the top of the base plate, and a guide rail is fixedly connected to the surface of the support plate A. The slider on the guide rail is connected to the support plate B by an M2.5 screw. The right base is installed on the support plate B by a D12 screw and locked with a D12 nut. The right base can rotate along the outer side of the D12 screw. Both the support plate A and the support plate B are equipped with locking components to loosen or lock the right base for height adjustment and vertical floating adjustment.

[0010] Preferably, the locking component includes a wrench A mounted on the support plate A and a wrench B mounted on the support plate B.

[0011] Preferably, both wrench A and wrench B are fixed by a set-off screw, which can effectively prevent wrench A and wrench B from loosening and slipping. When an object tends to detach, the head or nut of the set-off screw will directly block the movement of the object and limit its detachment stroke.

[0012] Preferably, a handle is fixedly connected to the right base for controlling its height adjustment and vertical floating adjustment, making it convenient for staff to perform adjustment operations.

[0013] Preferably, the lower clamping block is provided with a protrusion, and the upper clamping block is provided with a groove with the same cross-section as the protrusion. When the clamp is in use, the protrusion slides along the inside of the groove to maintain the linear movement between the upper and lower clamping blocks and avoid misalignment between the two, thereby affecting the normal clamping of the cloned key or key blank.

[0014] The method of using the above-mentioned horizontal key machine integrated fixture includes the following steps: Step 1: Mount the base plate onto the key machine, then place the key to be cloned on the clamping part of the left side of the base plate and the key blank to be processed on the clamping part of the right side. Step 2: Align the appropriate diamond-shaped edges on the top cover and the left base, then use the clamping components to clamp the key to be cloned or the key blank to be processed, and fix the adjusted left and right angles. Step 2: After both the cloned key and the key blank to be processed are clamped and their angles fixed, the clamp holding the key blank to be processed is then adjusted. This involves tightening wrench A and loosening wrench B, and using the handle to control the right base to rotate up and down around screw D, thereby causing the clamp to rotate up and down. Step 4: Tighten wrench B and loosen wrench A. Use the handle to control the right base to float up and down, thereby causing the clamp to float up and down. The right base drives the slider on the guide rail to move up and down along the guide rail through the support plate. After the positions of the up and down rotation and up and down movement are adjusted, tighten both wrench A and wrench B. Step 5: Perform contour cutting on the key blank to be processed.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the key to be cloned or the key blank to be processed is placed between the two clamping parts of the upper and lower clamping blocks. The appropriate rhomboid edges on the upper cover and the left base are aligned. Then, the upper clamping block is pressed by the clamping assembly to clamp the key to be cloned or the key blank to be processed, and the left and right angles can be changed. In this way, the clamp can be clamped at an angle. When encountering a key with a certain angle of tooth shape, it can also be processed, resulting in better performance. This solves the problem in the background technology that it cannot be tilted and cannot be processed when encountering a key with a certain angle of tooth shape, resulting in poor performance. 2. When wrench A controls the tightening and wrench B controls the loosening, the right base rotates up and down around screw D via the handle; thereby driving the fixture to rotate up and down. The up and down rotation facilitates arc processing; the small up and down floating can prevent the groove of the thick key from being not straight. 3. When wrench B controls the locking and wrench A is released, the right base is controlled to float up and down by the handle, thereby driving the clamp to float up and down. The right base drives the slider on the guide rail to move up and down along the guide rail. The small up and down floating can prevent the groove of the thick key from being not straight.

[0018] Example 1 like Figures 1 to 2 As shown, the present invention provides a horizontal key machine integrated fixture, including a base plate 1 and clamps 2 located on both sides of the top plate, one for clamping a cloned key and the other for clamping a key blank to be processed. The clamp 2 includes an upper clamping block 21 and a lower clamping block 22, with a spring 3 placed in the middle to control the rebound between the upper clamping block 21 and the lower clamping block 22. The horizontal key machine integrated fixture 2 also includes: Angle switch 4: It includes an upper cover 41 installed at the bottom of the lower clamping block 22, and a left base 42 installed below the upper cover 41. The two are fitted with a diamond-shaped edge for changing the angle of the clamp 2. Clamping assembly 5: It is rotatably connected to the left base 42.

[0019] In use, the key to be cloned or the key blank to be processed is placed between the two clamping parts of the upper clamping block 21 and the lower clamping block 22 (placed separately). The appropriate diamond-shaped edges on the upper cover 41 and the left base 42 are aligned. Then, the upper clamping block 21 is squeezed by the clamping component 5. The upper clamping block 21 will move downward under pressure, thereby bringing it closer to the lower clamping block 22. At the same time, pressure is also generated on the lower clamping block 22. Finally, the pressure is transmitted to the upper cover 41, which also presses the upper cover 41 and the left base 42 together. Thus, while controlling the tightness of the clamp 2, the left and right angles of the clamp 2 are locked simultaneously. This allows for the clamping of the cloned key or the key blank to be processed, as well as the conversion of the left and right angles. In this way, the clamp 2 can be clamped at an angle. When encountering a key with a certain angle in the tooth shape, it can also be processed, resulting in better performance.

[0020] Furthermore, the surface of the upper cover 41 is fixedly connected to the cover plate 43 by M4 screws 45. The connection method of M4 screws 45 makes the fixation more secure, thereby preventing the corner bracket 4 from loosening and falling off. In addition, the lower clamping block 22 is provided with a protrusion 15, and the upper clamping block 21 is provided with a groove 16 with the same cross-section as the protrusion 15. When the clamp 2 is in use, the protrusion 15 slides along the inside of the groove 16 to maintain the linear movement between the upper clamping block 21 and the lower clamping block 22, and avoid misalignment between the two, thereby affecting the normal clamping of the cloned key or key blank.

[0021] Example 2 like Figure 1 , Figure 2 as well as Figure 6 The specific structure of the clamping component 5 in Embodiment 1 is described in this embodiment: The clamping component 5 includes a screw 51 that passes through the upper clamping block 21, the lower clamping block 22 and the upper cover 41 in sequence and enters the left base 42. The spring 3 is sleeved on the screw 51 between the upper clamping block 21 and the lower clamping block 22. The screw 51 is fixed in the left base 42 by the D4 pin 52. The screw 51 can rotate along the outer wall of the D4 pin 52. The head of the screw 51 is threadedly connected to a locking wrench 53.

[0022] That is, the screw 51 can rotate along the outer wall of the pin, so that it can always remain perpendicular to the top of the upper clamping block 21. After the angle of the clamp 2 is adjusted, the locking wrench 53 is rotated clockwise, so that the locking wrench 53 moves downward along the screw 51 to press down the upper clamping block 21, thereby bringing it closer to the lower clamping block 22. At the same time, pressure is applied to the lower clamping block 22. Finally, the pressure is transmitted to the upper cover 41, which also presses the upper cover 41 and the left base 42 together. Thus, while controlling the tightness of the clamp 2, the left and right angles of the clamp 2 are locked simultaneously, so as to realize the clamping of the cloned key or key blank and the conversion of the left and right angles.

[0023] Example 3 like Figures 1-5 As shown, the existing horizontal key-cutting machine integrated fixture 2, when encountering thick keys, will result in a non-perpendicular cut, leading to inaccurate key cutting and difficulty in processing arcs. This embodiment further improves upon embodiment 1 by: a right base 44 is fixedly connected to the right side of the left base 42; a support plate A7 is fixedly connected to the top of the base plate 1; and a guide rail 8 is fixedly connected to the surface of the support plate A7. The slider on the guide rail 8 is connected to the support plate B10 via an M2.5 screw 9. The right base 44 is connected via a D... Screw 11 is installed on support plate B10 and locked with nut 12. The right base 44 can rotate along the outer wall of screw 11. Both support plate A7 and support plate B10 are equipped with locking components 13 to loosen or lock the height adjustment and vertical floating adjustment of the right base 44. The locking component 13 includes a wrench A1301 installed on support plate A7 and a wrench B1302 installed on support plate B10. A handle 6 is fixedly connected to the right base 44 for controlling its height adjustment and vertical floating adjustment.

[0024] It should be noted that the above structure is mainly applicable to the processing of key blanks. The above structure may not be installed on the clamp 22 that holds the cloned key in order to save costs.

[0025] After the key blank is clamped and the angle is adjusted according to the structure in Embodiment 1, wrenches A1301 and B1302 can be adjusted. When wrench A1301 controls the locking and wrench B1302 is released, the handle 6 controls the right base 44 to rotate up and down around screw D12 11, thereby driving the clamp 2 to rotate up and down. When wrench B1302 controls the locking and wrench A1301 is released, the handle 6 controls the right base 44 to float up and down, thereby driving the clamp 2 to float up and down. The side base 44 drives the slider on the guide rail 8 to move up and down along the guide rail 8 via the support plate B10. After the positions of the up and down rotation and up and down movement are adjusted, the wrench A1301 and the wrench B1302 are locked to fix the state of the fixture 2 (locking up and down rotation and up and down floating). Up and down rotation facilitates the processing of arcs; small up and down floating can prevent the groove of the thick key from being crooked. Based on the embodiment, the above problems are solved, making the integrated fixture 2 more effective.

[0026] Furthermore, both wrench A1301 and wrench B1302 are fixed by the locking screw 14, which can effectively prevent wrench A1301 and wrench B1302 from loosening and slipping off.

[0027] The present invention also provides a method for using the above-mentioned horizontal key machine integrated fixture: Step 1: Mount the base plate 1 onto the key machine, then place the cloned key on the clamping part of the clamp 2 on the left side of the base plate 1, and place the key blank to be processed on the clamping part of the clamp 2 on the right side. Step 2: Align the appropriate diamond-shaped edges on the top cover 41 and the left base 42, then use the clamping component 5 to clamp the key to be cloned or the key blank to be processed, and fix the adjusted left and right angles. Step 2: After both the cloned key and the key blank to be processed are clamped and the angle is fixed, the clamp 2 holding the key blank to be processed is then adjusted, that is, the control wrench A1301 is tightened and the wrench B1302 is loosened. The right base 44 is controlled to rotate up and down around the D12 screw 11 through the handle 6, thereby driving the clamp 2 to rotate up and down. Step 4: Tighten wrench B1302 and loosen wrench A1301. Control the right base 44 to float up and down through handle 6, thereby causing the clamp 2 to float up and down. The right base 44 drives the slider on the guide rail 8 to move up and down along the guide rail 8 through support plate B10. After the positions of the up and down rotation and up and down movement are adjusted, tighten both wrench A1301 and wrench B1302. Step 5: Perform contour cutting on the key blank to be processed.

[0028] The horizontal key machine integrated clamp and its method of use of the present invention have the following advantages: The key to be cloned or the key blank to be processed is placed between the two clamping parts of the upper clamping block 21 and the lower clamping block 22. The appropriate rhomboid edges on the upper cover 41 and the left base 42 are aligned. Then, the upper clamping block 21 is pressed by the clamping component 5 to clamp the key to be cloned or the key blank to be processed, and the left and right angles can be switched. In this way, the clamp 2 can clamp at an angle. When encountering a key with a certain angle of tooth shape, it can also be processed, and the use effect is better. This solves the problem in the background technology that it cannot be tilted and cannot be processed when encountering a key with a certain angle of tooth shape, resulting in poor use effect. When wrench A1301 controls the locking and wrench B1302 releases, the right base 44 is controlled by handle 6 to rotate up and down around screw D12 11; thereby driving the clamp 2 to rotate up and down. The up and down rotation facilitates the processing of arcs; the small up and down floating can prevent the groove of the thick key from being not straight.

[0029] When wrench B1302 controls the locking and wrench A1301 is released, the handle 6 controls the right base 44 to float up and down, thereby causing the clamp 2 to float up and down. The right base 44 drives the slider on the guide rail 8 to move up and down along the guide rail 8. The small up and down movement can prevent the groove of the thick key from being not straight.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
