[0029] See also Figures 1 to 3 As shown, a laser engraving fixture device includes a base 1 connected to the processing station of the laser engraving machine, a fixture assembly 3 connected to the base 1, and a contact button assembly 4 arranged on the base 1. Among them, the base 1 has a mounting groove 2, the fixture assembly 3 is installed and fixed in the mounting groove 2, the contact button assembly 4 is connected to the laser engraving machine signal, and the laser engraving operation of the laser engraving machine can be turned on by touching the contact button assembly 4. In this embodiment, the contact button assembly 4 is a conventional contact start button, and the signal connection between the contact button assembly 4 and the laser engraving machine can be realized through a conventional logic circuit, which is a mature existing technology and will not be described in detail here.

[0030] As described above, a placement hole 31 suitable for placing the workpiece 5 to be measured is formed on one side of the top of the gauge assembly 3, and the contact button assembly 4 is located directly below the placement hole 31. One end of the workpiece 5 to be measured passes through the placement hole 31 and abuts against the contact button assembly 4, and the other end is clamped with the edge of the placement hole 31. Therefore, the length of the workpiece 5 is detected by the distance between the placement hole 31 and the contact button assembly 4. If it is qualified, the workpiece 5 can touch the contact button assembly 4, and the laser engraving machine is turned on to perform laser engraving on the top of the workpiece 5. If it is unqualified and the length is not enough, the contact button assembly 4 cannot be touched. The entire detection process is incorporated into the laser engraving process, which will not waste processing time and greatly improve production efficiency.

[0031] Specifically, the gauge assembly 3 includes a fixed portion 32 connected to the base 1, and an adjusting portion 33 that can be raised and lowered relative to the fixed portion 32, and the above-mentioned placement hole 31 is formed on the adjusting portion 33. The adjusting portion 33 includes an adjusting knob 331 that is covered on the top of the fixed portion 32 and can rotate relative to the adjusting portion 33, and a lifting member 332 that is threadedly connected to the adjusting knob 331. Rotating the adjusting knob 331 can raise or lower the lifting member 332, thereby adjusting the distance between the placement hole 31 and the contact button assembly 4, so as to facilitate the measurement of workpieces 5 with different length requirements.

[0032] The top outer wall of the fixing portion 32 is partially recessed inward to form a first clamping portion 61321 of the clamping portion 61. The adjusting knob member 331 has a second clamping portion 613311 of the clamping portion 61. The inner diameter of the second clamping portion 613311 of the clamping portion 61 is equal to or slightly smaller than the outer diameter of the first clamping portion 61321 of the clamping portion 61, so that the adjusting knob member 331 can be covered on the fixing portion 32 and can rotate relatively. The adjusting knob member 331 extends from the second clamping portion 613311 of the clamping portion 61 to a direction away from the fixing portion 32 to form a first protruding portion 3312. The outer wall of the first protruding portion 3312 is formed with a first thread 3313. The inner wall of the lifting member 332 has a second thread 3321 adapted to the first thread 3313. The first thread 3313 and the second thread 3321 are connected in a threaded connection, so that the lifting member 332 can be raised or lowered when the adjusting knob member 331 is rotated.

[0033] The top of the lifting member 332 protrudes toward the side to form a second protruding portion 3322, and the placement hole 31 is formed on the second protruding portion 3322. The placement hole 31 includes a first through hole 311 and a second through hole 312 connected from top to bottom, and the workpiece 5 includes a screw 51 and a screw head 52 connected to the screw 51. The diameter of the first through hole 311 is larger than the diameter of the screw 51 and smaller than the diameter of the screw head 52, so as to facilitate the insertion operation of the workpiece 5, and the diameter of the second through hole 312 is equal to the diameter of the screw 51, so as to play a stable guiding role for the workpiece 5. In this embodiment, the connection between the first through hole 311 and the second through hole 312 is a slope 313, so as to prevent the workpiece 5 from being stuck between the first through hole 311 and the second through hole 312.

[0034] In order to limit the adjustment distance of the adjustment knob 331, in this embodiment, the gauge assembly 3 further includes a movable limiting component 6, one end of the movable limiting component 6 is fixedly connected to the fixed portion 32, and the other end extends into the lifting component 332, and the end extending into the lifting component 332 has a clamping portion 61, and the clamping portion 61 can be clamped with the top of the first protruding portion 3312. The clamping portion 61 is threadedly connected to the movable limiting component 6, and rotating the clamping portion 61 can make the clamping portion 61 rise or fall along the height direction of the movable limiting component 6, thereby limiting the adjustment distance by the distance between the clamping portion 61 and the adjustment knob 331.

[0035] In order to facilitate adjustment, an adjustment slot 3323 is opened on the side wall of the lifting member 332, and part of the clamping portion 61 is located in the adjustment slot 3323. The adjuster only needs to rotate the clamping portion 61 in the adjustment slot 3323 to make adjustments, which is simple and convenient.

[0036] To sum up: the laser engraving inspection fixture device of the utility model is provided with a base connected to the processing station of the laser engraving machine, a inspection fixture assembly installed in the mounting groove of the base, and a contact button assembly arranged on the base, wherein the laser engraving operation of the laser engraving machine can be started by touching the contact button assembly, and a placement hole suitable for placing the workpiece to be measured is formed on one side of the top of the inspection fixture assembly, and the contact button assembly is located directly below the placement hole, one end of the workpiece to be measured passes through the placement hole and abuts against the contact button assembly, and the other end is clamped with the edge of the placement hole, so that the length of the workpiece is detected whether it is qualified through the distance between the placement hole and the contact button assembly, if qualified, the workpiece can touch the contact button assembly, and the laser engraving machine is turned on to perform laser engraving operation on the top of the workpiece, and if it is unqualified and the length is insufficient, the contact button assembly cannot be touched, and the entire detection process is incorporated into the laser engraving process, which will not waste processing time and greatly improves production efficiency.
