Description of the Invention: [Technical Field] The present invention relates to an improved clamp for holding the blank key during cutting of a blank key, and is designed to be identical j is used to cut the key to the key cutter. [Prior Art] The prior art key-cutting machine is known to generally include a clamp and insert and clamp a blank key therein for subsequent milling. The operation assigns the desired mechanical code to the two white spoons, that is, the key tooth notch pattern: two types of the tongs or vise are typically provided in a conventional key cutter, and the spoon is used for the blank. a first clamp and a second clamp for holding the original key, the original key has been cut with the desired mechanical code therein. However, the updated key cutter is generally only used to hold the blank key. A single clamp, because it needs to be encoded, that is, cut desired: all information of the tooth = mouth pattern is selected and retrieved by an electronic storage memory, and the operation is directly transmitted to the cutting machine from there. zero Depending on the type of key involved, it can be suitably used for this particular purpose by using the locator device provided in the tongs itself, or by locking as much as possible, selectively inserted into the tongs. With reference to the components of the socket, the correct position of each key or blank key in its individual clamps is obtained. The fact that the two white extensions and the keys have different lengths depending on the application to which the keys belong or will be used may be optional. The positioning of the lock, that is, the component to be used for the clamp is a basic requirement. As for the key or the blank key itself, the top or the rear can be used as a locator mechanism, or another selection system, ^4723^ 1272148 A reference surface can be used as a shoulder mechanism for the blank key or as a positioner mechanism for the blank key.

Additionally, as best illustrated in the figures, The bridge member 102 has its outer or uppermost edge 1 〇 8 chamfered (defining the φ cut corner portions 108a, l 8b and l 8c) for better interface of the bridge 100 For the purpose of the edge of a shield (not shown), the shield is placed on the key cutter to protect the operator from the cutting tool. The 忒& plate 90 additionally includes a lower edge or inclined portion 1 1 局部 that partially defines the bottom of the insertion hole 96. In particular, the inclined lower edge 倾斜 is inclined or downward toward one of the outside of the clamp Gradually smaller, defined by the outer side surface 112 of the end plate 9 so as to be able to drop and leave the milling pieces caused during the cutting of the blank key, that is, to maintain a key cutting area. The purpose of continually cleaning and flaking the shavings is smoothly discharged or effectively transported away, and the key cutting area is defined as the area where the milling cutter is cutting the blank key κ. Correspondingly, one of the protruding surface portions 52 The angled surface 114 has a similar bevel that is generally engaged with the angled edge in a snap-fit relationship to provide a continuous oblique path for the blade to be detached from the cutting region. The clamp 12 further includes a mechanism for engaging the tip or distal end of the designated blank key to be encoded or cut by the key cutter. More particularly, in the particular embodiment shown, the mechanism for engaging the tip of the designated blank spoon or the distal end of 104723.doc -16 - 1272148 includes an upper edge 116 of the second end plate 92, the upper edge The plane of the jaw surface 52a is raised or raised upwardly, thereby forming a sharp stop stab or joint 丨丨8. The tip stop joint 丨丨 8 is particularly useful for a blank key having a relatively large length, such as the blank such that the (four) leading edge 104a engages or closely abuts the notch portion 1 〇 6 and a distal side thereof The end portion 120 circumscribes the tip stop joint (1). The distal end (2) of the stomach blank is also referred to herein as a tip and/or a tip portion.

For blanks of different lengths, in particular a blank key having a relatively short length, in the particular embodiment shown, the mechanism for engaging the tip or the retracted end of the designated blank is further comprised of a movable Tip abutment member 122. More specifically, the tip abutment member 122 is capable of providing a guide rib (not shown) as a chute on the inner surface 124 of the end plate 92, respectively, and a jaw 4Q extending parallel to the opposite surface 124. - the corresponding surface 126 slides 0 έ 对应 corresponds to the sweet claw surface 1 2 6 Ρ, the animal / si ^ Jr jaw surface 128 defines a recess in the jaw 40, which together with the surface 124, 126 form a groove 13 〇, The tip abutment member 122 is slidable within the groove as indicated by the double arrow 132. In the illustrated embodiment, the upper surface 134 of the tip abutment member 122 is attached to the listening surface 48, 5 (four) plane, and the member prevents the member 122 from becoming an obstruction on the cutting plane of the d. Additionally and advantageously, in the shackle specific κ embodiment, for example, a stop guide sleeve that limits the extent of its sliding is provided, and a plurality of adjacent mechanisms (not shown) of the squat type are provided, and along the grooves A slot (not shown) slides both to keep the tip abutment member 122 continuously grounded to the clamp 12, as is familiar to those skilled in the art, 104723.doc 1272148 and thus in the figures Not shown in the face. In operation, the tip abutment member 122 is movable between a projected position and a retracted position as indicated by arrow 132. In the retracted position (illustrated in Fig. 1), the tip abutment member 122 allows the distal end 120 of the blanking pocket κ to extend to and as close as possible to the tip stop joint 1] L8 of the end plate 92. In the extended position, the tip abutment member 122 extends toward the movable jaw 42' and provides a stop action for the distal end φ portion of the blank key having an appropriate or relatively short length. Thus, the clamp 12 is designed to accommodate a plurality of blank keys having different lengths. The distal second end plate 92 includes or defines an insertion aperture 140 therethrough. The end plate 92 additionally includes a lower edge or sloped portion 142 that defines the bottom of the insertion aperture 14''. In particular, the inclined lower edge 142 slopes downwardly or gradually toward the outside of the clamp and is defined by the outside of the surface 144 of the end plate 92 so as to be able to be caused during the cutting of the blank key K. The milling chips fall and leave, that is, to keep the key cutting area continuously cleaned and without the purpose of milling the chip, smoothly discharging or effectively transporting away. Correspondingly, the inclined surface 146 of the protruding surface portion 52 has a similar inclined surface which is generally engaged with the inclined edge 142 in a snap-fit relationship to provide a continuous inclined path for the chip on a large body. The crucible can cause the chips to fall off from the cutting area. The tongs 12 further comprise a confirmation member or mechanism, which in the particular embodiment shown is provided in the form of a stationary inspection member 150 formed on the upper surface 116 of the end plate 92.

In one embodiment, the cutter includes a contoured plate that is in contact with the stationary inspection member 150 on its sides. On the first side, the contoured plate determines whether the clamp 12 is correct for the selected key to be made or produced. The stationary inspection member 15 can have a particular size relative to the other clamps that enable the cutter to determine whether the clamp 12 is a suitable clamp for one of the selected keys. On the second side, when needed or desired, the y-plate is subjected to a setting and adjustment operation, and the clip can be established for the cutting tool (that is, the milling cutter of the cutting machine and the contouring plate itself). The reference dimension of a working plane of the pliers 12 and to be corrected. The clamp 12 of the non-specific embodiment also includes a reference or second inspection member 52 disposed on the movable jaw 42. More specifically, the second inspection member 152 of the particular embodiment shown is generally rectangular in shape and extends upwardly from the movable jaw top surface 50. The second inspection member 152 can be used in a variety of applications where it is desirable to consider the axis of the key blade 1 为 as a reference for a land cut. In a specific embodiment, after the blank key κ system is mounted and clamped to the clamp 12 to determine the width of the key blade 100, the inspection member 15 2 is detected by the profile plate of the cutting machine. Test or provide a reference. The cutting machine can include a mechanism for accommodating different blank key widths, and the mechanism operates with the second inspection member 152 when a certain width is detected by the engagement between the contour plate and the second inspection member 52 And/or being framed, 104723.doc -19- 1272148 will be corrected for an additional reference space. As illustrated, the clamp 12 may additionally include an indicator mark 154 on the cymbal, such as the end plate work 々 + λ ^ field of the embodiment towel, similar to the easy area (four), such The clips (4) are designed to be suitable for the work of the white type of the same type.

In operation, the 延 blank extension κ is inserted through the insertion hole 96 of the measurement, and the 〆 blade 100 is sinned on the surface 52a, wherein the blank spoon is tied in its cutting position. In the particular embodiment shown, the insertion of the blank key & occurs until the distal end 120 contacts or closely abuts the tip stop joint 118 and the head leading edge portion 10 is in contact or tight Adjacent to the notch portion 106. Since the portion 10 is matched or loaded into the notch portion 106, the user is notified or the blank key K is confirmed as a correct match for the clamp 12. In the case where the head of the blank key does not match the notch portion 106, the user is notified or the blank key is confirmed as an incorrect match for the clamp 12. If the blank key is a match, but a distal portion does not contact or closely rests adjacent the joint 118, the movable key tip abutment member 122 is moved toward its protruding position. The blank key K is properly inserted and confirmed as a match for the clamp. The handle 74 is formed to sandwich the blade 100 between the jaws 40, 42. More specifically, the rotation The handle 74 causes the threaded engagement pin 104723.doc -20 - 1272148. The pin 70 forcibly moves the movable jaw 42 toward the fixed jaw 4, I against the spring 6G' 62. The blank blade 100 is sandwiched therebetween. The bridge member 102 extends beyond the blade 1〇〇 to prevent the blank key κ from tipping over during cutting by a suitable key cutter. The clamp is mounted in the key cutter before or after the blank key κ is installed in the clamp 12, as is known and appreciated by those skilled in the art.

The clamp 12 can be used with any type of suitable key cutter; however, it is particularly suitable for use with the key cutter type described above with reference to the U.S. Patent Application, entitled "' Key Cutting Machine. Advantageously, the key cutter uses a low number of clamps, such as clamps, and in a preferred configuration, only four clamps are used, each clamp being similar to the clamp 12 but designed to fit Used with blank keys of various sizes. Furthermore, the key cutting machine is particularly suitable for establishing and/or replicating the field-type space currently used in the automotive industry, where one of the correct clamps and the matching blank key is the most important for quick and easy confirmation.
