Description

Technical Field

[0001] This utility model relates to the field of laser engraving technology, and in particular to a positioning and fixing device for laser engraving hard disk casings. Background Technology

[0002] In the process of laser engraving hard drive shells using a laser engraving machine, in order to ensure laser engraving accuracy, improve production consistency, and avoid product damage, a positioning and fixing device is usually installed on the laser engraving machine to position and fix the hard drive shell to be laser engraved. The existing positioning and fixing device usually consists of a support base, a positioning base, and a clamping plate.

[0003] For example, utility model application CN202222238740.1 discloses a laser engraving machine with a workpiece auxiliary positioning structure. Specifically, it includes a carrier plate, a fixed shell fixedly connected to the bottom surface of the carrier plate, a dual-head motor fixedly connected to the inner bottom wall of the fixed shell, two sliding grooves on the upper surface of the carrier plate, a clamping plate slidably connected to the inner wall of each sliding groove, and a threaded hole on the right side of each clamping plate. Two bearings are fixedly embedded in the inner wall of the fixed shell. This device, through the cooperation of the dual-head motor, threaded rod, clamping plate, threaded hole, carrier plate, and sliding grooves, uses the sliding grooves to position the clamping plate, and the operation of the dual-head motor allows the threaded rod to rotate within the threaded hole, enabling the two clamping plates to clamp and position the engraving material. This improves upon the slowness of manual operation, allowing workers to operate more quickly and further enhancing processing efficiency.

[0004] However, with current traditional positioning and fixing devices, the laser engraving process of the hard drive casing generates waste such as metal shavings or plastic microparticles. Due to their small size and easy adsorption, these wastes tend to accumulate in hidden locations such as the gaps formed when the clamping plate and the positioning base are in contact. To avoid the waste residue affecting the subsequent clamping accuracy and processing quality, the staff must wait for the clamping plate to move to both sides to loosen the hard drive casing before they can clean these exposed positioning blind spots. This operation is cumbersome and inconvenient to use. Utility Model Content

[0005] In view of this, the present invention provides a positioning and fixing device for laser engraving of hard disk casings, which has a collection tube that automatically cleans the waste residue in the exposed positioning blind area when the hard disk casing is released from its fixing. During the movement of the clamping frame, the first rack moves, and the movement of the first rack drives the control gear meshing with it to rotate. The rotation of the control gear drives the second rack to move, and the movement of the second rack drives the connecting slide to move. The movement of the connecting slide drives the mounting base to move. At the same time as the second motor starts, the drive fan starts to draw air and collect the metal chips or plastic particles generated during the laser engraving process through the collection tube.

[0006] This utility model provides a positioning and fixing device for laser engraving hard disk casings, specifically including: a laser engraving worktable; a fixed base is fixedly connected to the top surface of the laser engraving worktable; a sliding base is provided on the top surface of the fixed base; a control sliding base is fixedly connected to the bottom surface of the sliding base; the control sliding base is slidably connected inside the fixed base; two clamping frames are symmetrically slidably connected inside the sliding base; a mounting box is fixedly connected to the front surface of the sliding base; two connecting slides are symmetrically slidably connected inside the mounting box; the two connecting slides are respectively aligned with the positions of the two clamping frames; a mounting base is fixedly connected to the front surface of each of the two connecting slides; and a collection box is slidably connected inside each of the two mounting bases.

[0007] Optionally, a first motor is bolted to the front end of the fixed seat; an adjusting screw is coaxially fixed to the rear of the first motor shaft; and a control slide is threaded to the outside of the adjusting screw.

[0008] Optionally, a second motor is bolted to the right side of the sliding seat; a double-ended screw is coaxially fixed to the left side of the second motor shaft; the double-ended screw is rotatably connected inside the sliding seat; both clamping frames are threaded to the outside of the double-ended screw; a guide slide rod is fixedly connected to the left side of the sliding seat; the guide slide rod is disposed inside the two clamping frames.

[0009] Optionally, a first rack is fixedly connected to the front of each of the two clamping frames; both first racks are housed in the mounting box; two control gears are symmetrically rotatably connected to the front end of the sliding seat; both control gears are housed in the mounting box; the two first racks are respectively meshed with the upper parts of the two control gears; a second rack is respectively meshed with the lower parts of the two control gears; the two second racks are respectively fixedly connected to the rear of the two connecting slides; a guide slider is fixedly connected to the bottom end face of each of the two connecting slides; a guide slide is fixedly connected to the front end face of the mounting box; and the two guide sliders are slidably connected within the guide slide.

[0010] Optionally, a drive fan is bolted to the lower part of each of the two mounting bases; the drive fan is electrically connected to the second motor; a filter screen is provided on the bottom end face of each of the two collection boxes; a collection pipe is fixedly connected to the upper part of each of the two mounting bases; the ends of the two collection pipes are respectively fixedly connected to the two connecting slides.

[0011] Optionally, a connecting seat is fixedly connected to the front end face of each of the two mounting seats; a limiting block is slidably connected inside each of the two connecting seats; a set of support springs is fixedly connected to the bottom end face of each of the two limiting blocks; and the ends of the two sets of support springs are respectively fixedly connected to the top end face of the two connecting seats. Beneficial effects

[0012] During use, this invention starts the drive fan simultaneously with the second motor, which then draws air. As the clamping frame moves, it moves the first rack, which in turn rotates the control gear. This rotation of the control gear then moves the second rack, which in turn moves the connecting slide. During the movement of the connecting slide, the drive fan and collection pipe collect metal shavings or plastic particles generated during laser engraving and store them in a collection box. The synchronous movement of the connecting slide cleans the waste residue exposed in the gap after clamping, preventing it from affecting the positioning accuracy of the hard drive casing in subsequent operations. The operation is simple and quick, effectively improving the practicality of the positioning and fixing device and making it more convenient to use. Attached Figure Description

A mounting base 118 is fixedly connected to the front surface of each of the two connecting slides 115. A collection box 122 is slidably connected inside each of the two mounting bases 118.

[0025] A first motor 104 is bolted to the front end of the fixed base 101; an adjusting screw 105 is coaxially fixed to the rear of the first motor 104 shaft; and a control slide 102 is threaded to the outside of the adjusting screw 105.

[0026] A second motor 107 is bolted to the right side of the sliding seat 103; a double-ended screw 108 is coaxially fixed to the left side of the rotating shaft of the second motor 107; the double-ended screw 108 is rotatably connected inside the sliding seat 103; two clamping frames 106 are threaded to the outside of the double-ended screw 108; a guide slide rod 109 is fixedly connected to the left side of the sliding seat 103; the guide slide rod 109 is set inside the two clamping frames 106.

[0027] A first rack 112 is fixedly connected to the front of each of the two clamping frames 106; both first racks 112 are housed in the mounting box 110; the front end face of the sliding seat 103 is symmetrically rotatably connected to two control gears 113; both control gears 113 are housed in the mounting box 110; the two first racks 112 are respectively meshed with the upper parts of the two control gears 113; a second rack 114 is respectively meshed with the lower parts of the two control gears 113; the two second racks 114 are respectively fixedly connected to the rear of the two connecting slides 115; a guide slider 116 is fixedly connected to the bottom end face of each of the two connecting slides 115; a guide slide 111 is fixedly connected to the front end face of the mounting box 110; both guide sliders 116 are slidably connected in the guide slide 111.

[0028] A drive fan 123 is bolted to the lower part of each of the two mounting bases 118; the drive fan 123 is electrically connected to the second motor 107; a filter screen is provided on the bottom surface of each of the two collection boxes 122; a collection pipe 117 is fixedly connected to the upper part of each of the two mounting bases 118; the ends of the two collection pipes 117 are respectively fixedly connected to the two connecting slides 115.

[0029] The specific usage and function of this embodiment are as follows: Starting the first motor 104 drives the adjusting screw 105 to rotate. As the adjusting screw 105 rotates, it causes the control slide 102 to slide within the fixed base 101. The sliding of the control slide 102 causes the slide 103 to move, allowing the hard disk case on the slide 103 to move longitudinally, thus better aligning the hard disk case with the laser engraving head. Starting the second motor 107 causes the double-headed screw 108 to rotate. As the double-headed screw 108 rotates, it causes the two clamping frames 106 to move inward simultaneously, clamping and fixing the hard disk case. The guide slide 109 guides the clamping frames 106, facilitating laser engraving on the hard disk case via the laser engraving worktable 1. During the movement of the clamping frames 106, the first rack 112 moves. The movement of 112 will drive the control gear 113 to rotate, and the rotation of the control gear 113 will drive the second rack 114 to move. As the second rack 114 moves, it will drive the connecting slide 115 to move. During the movement of the connecting slide 115, the guide slider 116 will slide in the guide slide 111 to provide guidance for the connecting slide 115. The movement of the connecting slide 115 will drive the mounting base 118 to move. At the same time as the second motor 107 starts, the drive fan 123 will start. The drive fan 123 will start to draw air and collect the metal chips or plastic particles generated during the laser engraving process through the collection pipe 117 and store them in the collection box 122. The filter screen can block the metal chips or plastic particles and prevent them from entering the drive fan 123. Example 2
