Description

Technical Field

[0001] The utility model relates to the technical field of key tooth pattern machines, and particularly relates to a flagpole key tooth pattern machine. Background Art

[0002] Flagpole-shaped keys are one of the most common keys in the world, and their history can be traced back to the early Roman Empire. The locks that match these keys rely on certain obstacles or notches inside the keyhole to hold. If the key does not have a properly matching notch on the wheel piece, it cannot pass through these obstacles and cannot rotate, so the lock cannot be opened. To configure a flagpole key, a notch of the appropriate size and position needs to be filed on the wheel piece so that it can rotate after being inserted into the keyhole. However, there is no tooth pattern machine on the market today that can adapt to different models of flagpole keys. Most single-model tooth pattern machines can only manufacture single-model flagpole keys, which requires purchasing the corresponding model of tooth pattern machine when producing different models of flagpole keys, increasing the production cost.

[0003] For the above reasons, it is necessary to improve the existing technology. Summary of the Utility Model

Specific embodiments

[0027] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0028] Please refer to Figures 1-5 , the present utility model provides a flagpole key tooth pattern machine, including a machine tool main body 1, and a fixing part 10 for clamping the key is arranged on the machine tool main body 1;

[0029] A tooth pattern device 2, the tooth pattern device 2 includes a milling cutter seat 20, a milling cutter 21 arranged on the milling cutter seat 20, and a transmission device 22 for driving the milling cutter 21;

[0030] A first driving device 3, the first driving device 3 is used to drive the milling cutter seat 20 to move horizontally;

[0031] A second driving device 4, the second driving device 4 is used to drive the milling cutter seat 20 to move longitudinally;

[0032] A first limiting device 5, the first limiting device 5 includes a fixing seat 50 fixedly arranged on the milling cutter seat 20, a screw 51 arranged at one end of the fixing seat 50, and a tooth depth dial mechanism 52 fixedly arranged on one side of the screw 51;

[0033] A second limiting device 6, the second limiting device 6 includes a positioning rack 60 arranged on the milling cutter seat 20 and a pawl 61 cooperating with the positioning rack 60, the second driving device 4 is fixedly arranged on the path of the positioning rack 60, and the pawl 61 is arranged at one end of the second driving device 4.

[0034] In the above structure, after the staff uses the fixing part to fix the key, the transmission device is started to run the milling cutter. The first driving device is used to move the tooth device horizontally. At the same time, the screw rod abuts against the corresponding tooth depth pick to limit the horizontal movement distance of the tooth device, thereby pressing out tooth marks of different depths. The second driving device is used to drive the tooth device to move longitudinally. At the same time, the teeth at different positions on the positioning rack are engaged with the pawl to accurately locate the longitudinal movement distance. Through a simple structure, it is ensured that the tooth machine can make flagpole keys of different models. In this way, the utility model can be used to process various types of flagpole keys, thereby saving unnecessary expenses caused by the need to manufacture different types of tooth machines for processing different types of flagpole keys.

[0035] Specifically, a thimble bracket 11 is fixedly provided on the machine tool body 1, and a thimble 12 for limiting the position of the key is provided on the top of the thimble bracket 11. The thimble can be used to limit the position of the flagpole key during processing, effectively ensuring that the flagpole key is not displaced by force when a milling cutter is used to file the notch of the flagpole key.

[0036] Specifically, the machine tool body 1 includes a base plate 100, on which two first guide rails 101 are symmetrically arranged. The milling cutter seat 20 includes a large slide 200 used in conjunction with the first guide rail 101, a middle slide 202 used in conjunction with a second guide rail 201 horizontally arranged on the large slide 200, and a fixed plate 204 used in conjunction with a third guide rail 203 longitudinally arranged on the middle slide 202. The use of two symmetrically arranged first guide rails can effectively ensure that the overall position of the large slide does not shift when the large slide moves, and at the same time play the role of fixing the large slide and preventing the large slide from shaking.

[0037] Specifically, the first driving device 3 is a screw rod 30 for horizontally moving the middle drag plate 202 and a rotating rod 31 arranged at one end of the screw rod 30. The screw rod drives the longitudinal movement of the middle drag plate, thereby ensuring the accuracy and efficiency of the movement of the tooth flower device, effectively ensuring that no errors occur during manual operation. At the same time, the rotating rod is rotated to drive the screw rod to move the longitudinal tooth flower device, and the overall operation is simple.

[0038] Specifically, the second driving device 4 is a stepping swing arm used for the longitudinal movement of the fixed plate 204. The stepping swing arm is manually moved to drive the high-precision lateral movement of the middle carriage, thereby driving the tooth flower device to accurately change the lateral position.

[0039] Specifically, the tooth depth paddle mechanism 52 includes a paddle seat 520 and a plurality of tooth depth paddles 521 rotatably disposed on the paddle seat 520 , the tooth depth paddle 521 includes a plurality of teeth 522 of varying depths disposed thereon and a handle 523 disposed on one side of the tooth depth paddle 521 , and using the handle to move the position of the tooth depth paddle is more labor-saving.

[0040] Specifically, the transmission device 22 is a worm and worm gear reducer. Using a worm and worm gear reducer has the advantages of stable transmission, good transmission performance, low noise, high efficiency, etc.

[0041] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
