DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figure 1 — Fig.10As shown, the present invention provides: a laser chamfering device and a chamfering method for printer housing production, comprising a machine platform 1, a laser chamfering head 15, a clamping assembly 18 and a fixing assembly 19. The machine platform 1 is provided with a clamping assembly 18 for conveniently replacing the fixing assembly 19. The setting of the clamping assembly 18 makes it convenient to replace the fixing assembly 19, which greatly increases the flexibility and work efficiency of the device. When it is necessary to process printer housings of different sizes or shapes, the appropriate fixing assembly 19 can be quickly replaced. The printer housing body 2 is adsorbed on the fixing component 19; the fixing component 19 includes a connecting plate 193 and an adjusting plate 194, a driven gear 1943 for rotating the adjusting plate 194 is movably provided on the top of the connecting plate 193 through an axis, a driving gear 1942 for driving the driven gear 1943 to rotate is movably provided at the center position of the top of the connecting plate 193, and the driving gear 1942 and the driven gear 1943 are meshed with each other, the adjusting plate 194 is fixed to the driven gear 1943 by bolts, and a suction cup 1941 for adsorbing the printer housing body 2 is fixed at one end of the driven gear 1943, and the position of the adjusting plate 194 (and the suction cup 1941 thereon) can be easily adjusted through the meshing of the driving gear 1942 and the driven gear 1943, so as to adapt to printer housings of different sizes. One end of the suction cup 1941 is connected to the vacuum pump of the factory through a pipeline. By connecting to the vacuum pump of the factory, the suction cup 1941 can firmly absorb the printer housing to prevent displacement during the processing, ensuring the processing accuracy. Through precise fixing and adjustment, it can be ensured that the laser chamfering head 15 always maintains the correct position with the printer housing during the processing, thereby improving the processing accuracy. The clamping component 18 facilitates the replacement of the fixing component 19, and the flexible position adjustment of the suction cup 1941 greatly shortens the time for replacing the printer housing body 2 and improves work efficiency.

[0034] In this embodiment, when the driving gear 1942 rotates, the driving gear 1942 causes the driven gear 1943 to rotate, and then causes the adjustment plate 194 to rotate, so that the relative position between the adjustment plates 194 changes. The adaptive adjustment of the adjustment plate 194 and the suction cup 1941 can adapt to printer housings of different sizes, with a higher degree of adaptability and convenient adjustment.

[0035] There are four groups of adjustment plates 194, suction cups 1941 and driven gears 1943 evenly distributed on the connecting plate 193, and when the adjustment plate 194 rotates, it is used to change the position of the suction cup 1941 adsorbing the printer housing body 2. The adjustment plate 194 and the suction cup 1941 can ensure that the printer housing body 2 is evenly fixed at multiple points. This not only improves the stability of the fixation, but also helps to maintain the balance of the housing during the processing. The fixing assembly 19 also includes a fixing plate 191 and support columns 192, and the support columns 192 are distributed in a matrix on the fixing plate 191, one end of the support column 192 is fixedly connected to the surface of the fixing plate 191, and the other end of the support column 192 is fixedly connected to the bottom of the connecting plate 193.

[0036] A rotating driving member 1944 is fixed to the center position of the bottom of the connecting plate 193 by bolts. The rotating driving member 1944 is used to drive the driving gear 1942 to rotate. The output end of the rotating driving member 1944 passes through the connecting plate 193 and is connected to the shaft on the driving gear 1942.

[0037] In this embodiment, the operator only needs to control the rotating driving member 1944 to achieve precise control of the driving gear 1942, and then adjust the position of the driven gear 1943 and the suction cup 1941, so as to achieve adjustment and fixation according to the size of the printer housing. Since the adjustment process becomes more automated and precise, the operator can complete the fixing and position adjustment of the printer housing more quickly, thereby improving the efficiency of the entire processing process.

[0038] The clamping assembly 18 includes a support plate 181 and a first slide rail 1821. The first slide rail 1821 is fixed at the center position of the bottom of the support plate 181 along the length direction of the support plate 181. A first clamping block 182 for clamping the fixed plate 191 is slidably arranged on the first slide rail 1821. Two through grooves 1811 are symmetrically provided on the support plate 181. One end of the first clamping block 182 passes through the through groove 1811 and contacts the outside of the fixed plate 191. The first slide rail 1821 provides a sliding track for the first clamping block 182. By sliding the first clamping block 182, the fixed plate 191 can be clamped or released. Since the first clamping block 182 can slide on the first slide rail 1821, the operator can easily adjust the position of the clamping block to adapt to fixed plates 191 of different sizes. This design greatly improves the convenience of replacing the fixed assembly 19.

[0039] The clamping assembly 18 also includes a second clamping block 185 and a second slide rail 1851. The second clamping block 185 is slidably arranged on the second slide rail 1851, and the second slide rail 1851 is symmetrically arranged on the support plate 181 along the width direction of the support plate 181. The second clamping block 185 extends to the upper surface of the support plate 181 and contacts the outside of the fixed plate 191. In addition to the original clamping mechanism of the first clamping block 182 and the first slide rail 1821 along the length direction of the support plate 181, the second clamping block 185 and the second slide rail 1851 provide a clamping force along the width direction of the support plate 181. This double clamping mechanism ensures stable clamping of the fixed plate 191 and effectively prevents displacement or vibration during processing. This symmetrical design not only improves the stability of clamping, but also helps to extend the service life of the clamping assembly 18.

[0040] A slide 186 is also provided on the first slide rail 1821, and the slide 186 is symmetrical about the center position of the support plate 181, and the bottom surface of the slide 186 is movably connected to a connecting rod 184 for moving the second clamping block 185, and the other end of the connecting rod 184 is movably connected to the bottom surface of the second clamping block 185 through an axis, and a telescopic driving member 183 is connected to the side of one of the slides 186, and the output end of the telescopic driving member 183 is interconnected with the outer surface of the other slide 186.

[0041] The two slides 186 can move synchronously or independently along the first slide rail 1821. When the slides 186 move on the first slide rail 1821, they drive the second clamping block 185 to move on the second slide rail 1851 through the connecting rod 184. By controlling the extension and contraction of the telescopic drive member 183, the positions of the two second clamping blocks 185 on the second slide rail 1851 can be synchronously adjusted. When the telescopic drive member 183 is shortened, the two slides 186 will approach each other, and through the action of the connecting rod 184, the second clamping blocks 185 will also approach each other, thereby clamping the fixed plate 191. Conversely, when the telescopic drive member 183 is extended, the two second clamping blocks 185 will move away from each other, releasing the fixed plate 191, and similarly, the first clamping block 182 will also move closer and farther synchronously accordingly.

[0042] A longitudinal moving component 11 for reciprocating motion of the laser chamfering head 15 along the Y-axis is also provided at a position near the clamping component 18 on the top of the machine 1, a second lateral moving component 17 for reciprocating motion of the laser chamfering head 15 along the X-axis is provided on the longitudinal moving component 11, a vertical moving component 12 for reciprocating motion of the laser chamfering head 15 along the Z-axis is provided on the second lateral moving component 17, a first lateral moving component 13 for reciprocating motion of the laser chamfering head 15 along the X-axis direction is provided on the vertical moving component 12, a rotating head 14 for angle adjustment of the laser chamfering head 15 is provided on the first lateral moving component 13, a disassembly component 16 for convenient disassembly of the laser chamfering head 15 is provided on the top of the rotating head 14, the laser chamfering head 15 is inserted into the rotating head 14 and is used to chamfer the printer housing body 2.

[0043] In this embodiment, the laser chamfering head 15 is moved along the Y axis by the longitudinal moving component 11, the laser chamfering head 15 is moved along the X axis by the second transverse moving component 17, and the laser chamfering head 15 can also be moved along the X axis by the first transverse moving component 13. At this time, the vertical moving component 12 can make the first transverse moving component 13 move along the Z axis, so that the laser chamfering head 15 is close to the corresponding position of the printer housing body 2. By starting the laser chamfering head 15, the laser chamfering head 15 emits a high-energy laser beam to irradiate the corresponding position of the printer housing body 2. According to the preset program of the device, the longitudinal moving component 11, the vertical moving component 12, the first transverse moving component 13, the rotating head 14 and the second transverse moving component 17 cooperate with each other to chamfer the printer housing body 2. Through the flexible movement and angle adjustment function in the above three-dimensional space, the laser chamfering head 15 can be accurately positioned at any position of the printer housing body 2 and perform efficient chamfering processing. This helps to improve processing accuracy, reduce processing errors, and ensure that the appearance and quality of the printer housing meet the design requirements.

[0044] The disassembly assembly 16 includes a protective box 164, which is fixed on the top of the rotating head 14. Four screws 162 are distributed around the protective box 164. One end of the screw 162 is connected to a knob 161. The other end of the screw 162 passes through the protective box 164 and is movably connected to a clamp 163, and the clamp 163 is clamped to the surface of the laser chamfering head 15.

[0045] In this embodiment, by rotating each knob 161, the knob 161 can rotate the screw 162, and the screw 162 can separate the clamp 163 from the laser chamfering head 15. At this time, the laser chamfering head 15 can be removed for replacement, providing a convenient and safe operation method for replacement and maintenance of the laser chamfering head 15. This design not only improves the maintainability of the equipment, but also ensures the stability and safety of the laser chamfering head 15 during the replacement process.

[0046] Working principle of the present invention:

[0047] When in use, the driving member 1944 is rotated to drive the driving gear 1942 to rotate, and the driving gear 1942 is meshed with the driven gear 1943, so that the driven gear 1943 is rotated, so that the position of the adjustment plate 194 changes, and the suction cup 1941 is adjusted to a suitable position, and then the printer housing body 2 is placed on the suction cup 1941, and the printer housing body 2 is fixed by the suction cup 1941, and the laser chamfering head 15 is moved by the longitudinal moving component 11. The laser chamfering head 15 moves along the Y-axis, the second lateral moving assembly 17 makes the laser chamfering head 15 move along the X-axis, and the first lateral moving assembly 13 can also make the laser chamfering head 15 move along the X-axis. At this time, the vertical moving assembly 12 can make the first lateral moving assembly 13 move along the Z-axis, so as to make the laser chamfering head 15 close to the corresponding position of the printer housing body 2. By starting the laser chamfering head 15, the laser chamfering head 15 emits a high-energy laser beam to irradiate the corresponding position of the printer housing body 2. According to the preset program of the device, the longitudinal moving assembly 11 and the vertical moving assembly 13 move along the Y-axis, and the second lateral moving assembly 17 makes the laser chamfering head 15 move along the X-axis, and the first lateral moving assembly 13 can also make the laser chamfering head 15 move along the X-axis. At this time, the vertical moving assembly 12 can make the first lateral moving assembly 13 move along the Z-axis, so as to make the laser chamfering head 15 close to the corresponding position of the printer housing body 2. The part 12, the first lateral moving component 13, the rotating head 14 and the second lateral moving component 17 cooperate with each other to chamfer the printer housing body 2, which can achieve accurate cutting of the edge of the workpiece, meet the high-precision processing requirements, and greatly improve the production efficiency. The laser chamfering head 15 can also be easily disassembled and replaced. When the laser chamfering head 15 is to be replaced, the knobs 161 are turned, and the knobs 161 can rotate the screw 162, and the screw 162 can separate the clamp 163 from the laser chamfering head 15. At this time, the laser chamfering head 15 can be removed for replacement. In order to make the equipment adapt to different parts, the equipment adopts a modular design. By starting the telescopic driving member 183, the telescopic driving member 183 causes the slide 186 to move, and the movement of the slide 186 causes the connecting rod 184 to move, so that the second clamping block 185 can move, so that the first clamping block 182 can also move synchronously, and the first clamping block 182 and the second clamping block 185 are separated from the fixing assembly 19, so that the fixing assembly 19 can be removed, so that the equipment can replace different fixing assemblies 19 according to different parts.

It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
