[0002] A key duplication fixture is a specialized device used to hold the key prototype and key blank during the key duplication process. Its main function is to ensure that the key prototype and key blank remain stable and accurately positioned during the duplication process, allowing the key duplicator to precisely process the key blank according to the tooth shape, groove shape, and other features of the prototype key, thereby improving the accuracy and quality of key duplication. A common clamp-type fixture consists of two clamping parts with a groove between them for holding the key. The distance between the clamping parts is adjusted manually by turning a threaded handle to accommodate keys of different thicknesses. This type of fixture has a simple structure, but its applicability to different keys is limited, and manual adjustment is prone to errors.

[0003] To accommodate more key blanks, Chinese utility model CN216990858U (publication date: 2022.03) discloses a multi-functional flat milling and vertical milling integrated fixture for key machines, including a fixture and a base. The fixture and the base are connected by a first fixing component. The fixture includes a first fixture component, a second fixture component, a gasket, and a baffle. The first fixture component and the second fixture component are slidably connected by a first connecting component. The first fixture component and the second fixture component are each provided with a first boss, a second boss, and a third boss. The fixture is provided with a first slide rail, and the gasket and the baffle are slidably connected to the fixture through the first slide rail.

[0004] The aforementioned key-cutting clamp can achieve the purpose of multiple uses in one machine, but it still cannot meet the processing needs of some special keys, such as cloverleaf hollow keys and short handle keys. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a multifunctional key-cutting clamp that can be adapted to the processing of various keys, especially some special keys.

[0006] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

[0007] A multifunctional key-cutting clamp includes a first fixed clamping block, a sliding clamping block, and a second fixed clamping block. The sliding clamping block is slidably disposed between the first and second fixed clamping blocks, forming multiple workstations with the first and second fixed clamping blocks respectively. A first workstation and a second workstation are provided between the sliding clamping block and the first fixed clamping block. The first workstation is formed by an upper step, and the second workstation is formed by a lower groove. The first workstation is adapted to a short-handled key with a detachable pressure plate. After installation, the pressure plate covers the upper part of the side of the short-handled key. The opposite sides of the first fixed clamping block and the sliding clamping block are provided with clamping notches. The clamping notches form a processing station adapted to a hollow key with a plum blossom shape. The clamping notches penetrate through the first and second workstations.

[0008] In the aforementioned multifunctional key-cutting clamp, the front end of the sliding clamp block is formed with an upwardly protruding sliding protrusion, and the front end of the second fixed clamp block is formed with an upwardly protruding fixed protrusion. A third station and a fourth station are provided between the sliding protrusion and the fixed protrusion. The third station is formed by an upper step, and the fourth station is formed by a lower step. The third station and the fourth station are used in conjunction with a gasket.

[0009] In the aforementioned multifunctional key-cutting fixture, the rear end of the sliding clamp and the rear end of the second fixed clamp form a fifth station and a sixth station, respectively. The fifth station is formed by an upper step, and the sixth station is formed by a lower step.

[0010] In the aforementioned multi-functional key cutting fixture, the second station is adapted to dotted keys (keys that require dotting, such as Wangli third-generation keys), the third station is adapted to internal and external milled groove keys, the fourth station is adapted to cross keys or irregular keys, the fifth station is adapted to dotted and internally milled groove keys, and the sixth station is adapted to punched semi-circular keys or side-milled groove keys.

[0011] In the aforementioned multifunctional key-cutting clamp, a laterally extending positioning structure is provided between the first fixed clamping block and the sliding clamping block, and between the second fixed clamping block and the sliding clamping block, respectively. The positioning structure includes mutually cooperating grooves and protrusions.

[0012] In the aforementioned multifunctional key-cutting clamp, the top of the first fixing block is provided with a mounting hole, and the pressure plate is detachably connected to the first fixing block by fasteners screwed into the mounting hole; furthermore, the pressure plate is provided with various specifications to adapt to short-handle keys of different specifications.

[0013] In the aforementioned multifunctional key-cutting clamp, the first fixing block and the second fixing block form an integral U-shaped structure.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 :

[0025] A multifunctional key cutting clamp includes a first fixed clamping block 1, a sliding clamping block 2, and a second fixed clamping block 3. The sliding clamping block 2 is slidably disposed between the first fixed clamping block 1 and the second fixed clamping block 3, forming multiple workstations with the first fixed clamping block 1 and the second fixed clamping block 3 respectively. A first workstation 4 and a second workstation 5 are provided between the sliding clamping block 2 and the first fixed clamping block 1. The first workstation 4 is formed by an upper step, and the second workstation 5 is formed by a lower groove. The first workstation 4 is adapted to a short handle key with a detachable pressure plate. After installation, the pressure plate covers the upper part of the side of the short handle key. The second workstation 5 is adapted to a dotted key. The opposite sides of the first fixed clamping block 1 and the sliding clamping block 2 are provided with clamping notches 6. The clamping notches 6 form a processing station adapted to a hollow key with a plum blossom shape. The clamping notches 6 penetrate the first workstation 4 and the second workstation 5.

[0026] The specific installation method of the pressure plate is as follows: the top of the first fixing block 1 is provided with a mounting hole 13, and the pressure plate is detachably connected to the first fixing block 1 by fasteners screwed into the mounting hole 13; furthermore, the pressure plate is provided with various specifications to adapt to short handle keys of different specifications.

[0027] When processing a short handle key using the first station 4, a suitable pressure plate is installed on the first fixed clamping block 1, and then the short handle key is placed. The sliding clamping block 2 is moved towards the first fixed clamping block 1 so that the sliding clamping block 2 clamps the short handle key with the first fixed clamping block 1. The steps and clamping plates formed on the sliding clamping block 2 and the first fixed clamping block 1 of the first station 4 jointly position and fix the short handle key, and then the short handle key can be processed to open the teeth.

[0028] When processing a key with dots (such as a Wangli third-generation key) using the second station 5, remove the pressure plate and move the sliding clamp 2 towards the first fixed clamp 1 so that the sliding clamp 2 clamps the key with the first fixed clamp 1. The grooves formed on the sliding clamp 2 and the first fixed clamp 1 of the second station 5 are used to position and fix the key, and then the key can be processed with dots.

[0029] When machining a hollow plum blossom key, remove the pressure plate, place the hollow plum blossom key at the corresponding position of the clamping notch 6, and then move the sliding clamping block 2 towards the first fixed clamping block 1 so that the sliding clamping block 2 clamps the key with the first fixed clamping block 1. Then the key can be milled.

[0030] Furthermore, the front end of the sliding clamping block 2 is formed with an upwardly protruding sliding protrusion 7, and the front end of the second fixed clamping block 3 is formed with an upwardly protruding fixed protrusion 8. A third station 9 and a fourth station 10 are provided between the sliding protrusion 7 and the fixed protrusion 8. The third station 9 is formed by an upper step, and the fourth station 10 is formed by a lower step. The third station 9 and the fourth station 10 are used in conjunction with a gasket. The third station 9 is adapted to an internal or external milling groove key, and the fourth station 10 is adapted to a cross key or an irregular key.

[0031] When machining internal and external milled groove keys using the third station 9, the sliding clamp 2 is moved towards the second fixed clamp 3, clamping the key between the sliding clamp 2 and the second fixed clamp 3. The steps formed on the sliding clamp 2 and the second fixed clamp 3 of the third station 9 jointly position and fix the key, allowing for internal and external milled groove machining. When machining cross keys or irregular keys using the fourth station 10, the sliding clamp 2 is moved towards the second fixed clamp 3, clamping the key between the sliding clamp 2 and the second fixed clamp 3. The steps formed on the sliding clamp 2 and the second fixed clamp 3 of the fourth station 10 jointly position and fix the key, allowing for the necessary machining. When using the third station 9 and the fourth station 10, a shim can also be used. The shim is placed in the gap between the second fixed clamp 3 and the sliding clamp 2, below the key, to support it. This, together with the sliding protrusion 7 and the fixed protrusion 8, forms the key's positioning and fixing structure.

[0032] Furthermore, the rear end of the sliding clamp 2 and the rear end of the second fixed clamp 3 form a fifth station 11 and a sixth station 12. The fifth station 11 is formed by an upper step, and the sixth station 12 is formed by a lower step. The fifth station 11 is adapted to a dotting and internal milling groove key, and the sixth station 12 is adapted to a drilling semi-circular key or a side milling groove key.

[0033] To facilitate the use of the fifth station 11 and the sixth station 12, the rear end of the fixture needs to be turned around to move to the front end. The specific turning structure is as follows: the first fixed clamping block 1 and the second fixed clamping block 3 are fixed on the mounting plate 16, and the mounting plate 16 is detachably connected to the base 17. The switching between the front and rear stations is achieved by turning the mounting plate 16 around. Specifically, the first station 4, the second station 5, the third station 9 and the fourth station 10 are front-end stations, and the fifth station 11 and the sixth station 12 are rear-end stations.

[0034] Furthermore, the mounting plate 16 is mounted on the base 17 via a dovetail groove. The base 17 is provided with a locking mechanism for locking the mounting plate 16. The locking mechanism includes a locking plate 18 and a locking screw 19. The locking plate 18 is fixed to the front end of the base 17, and the locking screw 19 is screwed to the locking plate 18 and passes through a through hole on the base 17 to abut and lock against the mounting plate 16. Furthermore, a wrench is provided at the outer end of the locking screw 19 to drive its rotation. When it is necessary to turn around, the locking screw 19 is unlocked, the mounting plate 16 is pulled out, it is turned around and reinstalled into the base 17, and then locked again by the locking screw 19.

[0035] When using the fifth station 11 to process dotted and internally milled keys, the sliding clamp 2 is moved towards the second fixed clamp 3, so that the sliding clamp 2 and the second fixed clamp 3 clamp the key. The steps formed on the sliding clamp 2 and the second fixed clamp 3 of the fifth station 11 are used to position and fix the key. Then, the key can be processed for dotting and internal milling. When using the sixth station 12 to process drilled semi-circular keys or side-milled keys, the sliding clamp 2 is moved towards the second fixed clamp 3, so that the sliding clamp 2 and the second fixed clamp 3 clamp the key. The grooves formed on the sliding clamp 2 and the second fixed clamp 3 of the sixth station 12 are used to position and fix the key. Then, the semi-circular key can be drilled or the key can be side-milled.

[0036] The first fixed clamping block 1 and the sliding clamping block 2, and the second fixed clamping block 3 and the sliding clamping block 2 are respectively provided with laterally extending positioning structures, the positioning structures including mutually cooperating grooves and protrusions.

[0037] In this embodiment, the sliding structure of the sliding clamp 2 is as follows: the first fixed clamp 1 and the second fixed clamp 3 form an integral U-shaped structure, and a pair of slide rods 14 are provided between the first fixed clamp 1 and the second fixed clamp 3. The sliding clamp 2 is slidably mounted on the slide rods 14 and driven by the adjusting threaded rod 15. Furthermore, the outer end of the adjusting threaded rod 15 is provided with an adjusting knob for driving its rotation, and the adjusting knob is located outside the first fixed clamp 1. By rotating the adjusting knob in different directions, the sliding clamp 2 can be driven to slide towards the first fixed clamp 1 or the second fixed clamp 3.

[0038] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
