Description

Technical Field

[0002] Precision instrument processing is to carry out corresponding processing on precision workpieces according to implementation requirements, such as laser welding, cutting, punching, laser coding and other processing. Among them, laser coding is to process the surface of the workpiece. Some workpieces are cylindrical. Since the outer surface is curved, corresponding rotary laser equipment is required for processing. The cylindrical workpiece is mainly clamped and rotated to achieve the effect of comprehensive coding.

[0003] During the laser coding process on the outer ring of the cylindrical shaft, the cylindrical shaft needs to be manually installed on the device and then manually disassembled after laser coding. If a large number of workpieces are processed, the workpieces need to be repeatedly disassembled and assembled, which leads to slow workpiece processing efficiency and increases the labor intensity of the staff in vain. To address the above problems, we have launched a rotary laser processing equipment for precision instruments. Utility Model Content

[0026] The utility model discloses a rotary laser processing device for a precision instrument, which is mainly used in the scene of laser processing of precision workpieces.

[0027] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5A rotary laser processing device for precision instruments comprises a housing 1, wherein the lower ends of the front and rear sides of the housing 1 are provided with first chutes 2; a clamping mechanism 4 is slidably arranged inside the first chutes 2, and the clamping mechanism 4 is used for clamping and fixing the cylindrical shaft; a conveying mechanism 3 is arranged at the lower end of the housing 1, and the conveying mechanism 3 is used for conveying the cylindrical shaft material; the clamping mechanism 4 comprises a rotating motor 402 slidably connected to the inside of the first chutes 2, and a disc 403 is connected to the output end of the rotating motor 402, and the disc 403 is provided at the middle of one side close to the horizontal vertical center axis of the housing 1 There is a second slide groove 404, and arc-shaped clamps 405 are slidably connected at the left and right ends of the second slide groove 404. Air pipe joints 407 are installed at the left and right ends of the disc 403. A micro cylinder 406 is connected to the arc-shaped clamp 405 away from the vertical central axis of the disc 403. A telescopic cylinder 401 is installed in the middle of the side of the support frame 301 away from the horizontal vertical central axis of the shell 1. The telescopic cylinder 401 is transmission-connected to the rotating motor 402. A laser emitter 8 is installed at the lower end of the slider 6. Arc-shaped placement boxes 304 are equidistantly installed on the outer surface of the rack 303.

[0028] In the present embodiment, in order to reduce the phenomenon of manual repeated disassembly and assembly of cylindrical shafts during batch processing of cylindrical shafts, the cylindrical shafts are first transported to the inside of the housing 1 by the transport mechanism 3 and then stop. At this time, the unprocessed cylindrical shaft is flush with the position of the rotating motor 402. The telescopic cylinder 401 is driven to extend, prompting the rotating motor 402 to slide upward along the first slide groove 2. The disc 403 and the arc-shaped clamp 405 are synchronously displaced upward. During the upward displacement of the arc-shaped clamp 405, it contacts the unprocessed cylindrical shaft, lifts the cylindrical shaft upward, and takes it out of the arc-shaped placement box 304. After the cylindrical shaft is separated from the arc-shaped placement box 304, the telescopic cylinder 401 stops extending, and air pressure is connected through the air pipe joint 407 to drive the micro cylinder 406 to extend, prompting the left and right groups of arc clamps 405 to slide toward the middle along the second slide groove 404. The cylindrical shaft is clamped and fixed by the two groups of arc clamps 405 to ensure that it cannot be separated. At this time, the laser emitter 8 is used to move the outer surface of the cylindrical shaft The surface is coded. Since the outer surface of the cylindrical shaft needs to be processed all around, the rotating motor 402 is driven to drive the disc 403 to rotate, prompting the two groups of arc-shaped clamps 405 to clamp the cylindrical shaft and rotate, thereby achieving the effect of processing the other surfaces of the cylindrical shaft. After the cylindrical shaft is processed, the rotating motor 402 is started to ensure that the direction of the cylindrical shaft is reset, and then the micro cylinder 406 is driven to shrink, and the clamping of the cylindrical shaft by the two groups of arc-shaped clamps 405 is released. The telescopic cylinder 401 shrinks and resets, and the rotating motor 402 carries the disc 403, the arc-shaped clamp 405 and the cylindrical shaft to descend synchronously. During the descent, the cylindrical shaft falls back into the arc-shaped placement box 304, and then the conveying mechanism 3 conveys the processed cylindrical shaft to the right, and the other group of unprocessed cylinders are flush with the position of the rotating motor 402. The above processing is repeated, thereby automatically installing and disassembling the cylindrical shaft through the equipment, reducing the labor intensity of the staff and improving the production and processing efficiency.

[0029] Reference Figure 1 and Figure 2 In a preferred embodiment, the conveying mechanism 3 includes support frames 301 installed at the front and rear ends below the housing 1, and the left and right bearings on the inner sides between the two sets of support frames 301 are connected with gear shafts 302, and the outer surface of the gear shaft 302 is installed with a rack 303. A material receiving box 5 is arranged on the right side of the conveying mechanism 3, and the height of the material receiving box 5 is lower than the height of the support frame 301;

[0030] This embodiment: In the above scheme, the unprocessed cylindrical shaft needs to be transported. However, in order to improve processing efficiency and reduce labor, first, the staff only needs to place the unprocessed cylindrical shaft in the arc-shaped placement box 304 on the left side of the upper end of the equipment, and the gear shaft 302 is driven by the motor to rotate, and the transmission rack 303 circulates. At this time, the arc-shaped placement box 304 with the cylindrical shaft is transported to the right to the inside of the shell 1 and then stops. The cylindrical shaft is laser-coded. At that time, the arc-shaped placement box 304 installed on the left side of the outer surface of the rack 303 is in The machine is in an empty state, and the staff puts the unprocessed cylindrical shaft into it for processing. At this time, the cylindrical shaft that was originally in laser coding is processed, and the motor drives the processed cylindrical shaft to continue to be transported to the right again. The unprocessed cylindrical shaft is transported to the outer shell 1 for processing, and when the processed cylindrical shaft is transported to the rightmost position, the angle of the arc-shaped placement box 304 is changed to pour the processed cylindrical shaft into the receiving box 5 for collection, thereby achieving the effect of simple loading and automatic unloading, indirectly improving the processing efficiency and reducing the labor intensity of the staff.

[0031] Reference Figure 1 and Figure 3 In a preferred embodiment, a slider 6 is slidably connected to the upper end of the housing 1, and a screw rod 7 is threadedly connected to the middle of the slider 6;

[0032] Supplementary explanation: During the process of coding the outer surface of the cylindrical shaft by the laser emitter 8, since the position of the laser emitter 8 is fixed, it is impossible to process other positions of the cylindrical shaft. The motor drives the screw rod 7 to cause the slider 6 to move forward and backward, thereby facilitating the laser emitter 8 to process other positions of the cylindrical shaft.

[0033] Working principle: When in use, in the process of batch processing of cylindrical shafts, in order to reduce the phenomenon of manual repeated disassembly and assembly of cylindrical shafts, the cylindrical shaft is first transported to the inside of the shell 1 through the conveying mechanism 3 and then stops. At this time, the unprocessed cylindrical shaft is flush with the position of the rotating motor 402, and the telescopic cylinder 401 is driven to extend, prompting the rotating motor 402 to slide upward along the first slide groove 2, and the disc 403 and the arc clamp 405 are synchronously displaced upward. During the upward displacement of the arc clamp 405, it contacts the unprocessed cylindrical shaft, lifts the cylindrical shaft upward, and takes it out from the arc placement box 304. After the cylindrical shaft is separated from the arc placement box 304, the telescopic cylinder 401 stops extending, and air pressure is connected through the air pipe joint 407 to drive the micro cylinder 406 to extend, prompting the left and right groups of arc clamps 405 to slide toward the middle along the second slide groove 404, and the cylindrical shaft is clamped and fixed by the two groups of arc clamps 405 to ensure that it cannot be separated. At this time, the laser emitter 8 The outer surface of the shaft is coded. Since the outer surface of the cylindrical shaft needs to be processed all around, the rotating motor 402 is driven to drive the disc 403 to rotate, prompting the two groups of arc-shaped clamps 405 to clamp the cylindrical shaft and rotate, thereby achieving the effect of processing the other surfaces of the cylindrical shaft. After the cylindrical shaft is processed, the rotating motor 402 is started to ensure that the direction of the cylindrical shaft is reset, and then the micro cylinder 406 is driven to shrink and release the clamping of the cylindrical shaft by the two groups of arc-shaped clamps 405. The telescopic cylinder 401 shrinks and resets, and the rotating motor 402 carries the disc 403, the arc-shaped clamp 405 and the cylindrical shaft to descend synchronously. During the descent, the cylindrical shaft falls back into the arc-shaped placement box 304, and then the conveying mechanism 3 conveys the processed cylindrical shaft to the right, and the other group of unprocessed cylinders are flush with the position of the rotating motor 402. The above processing is repeated, thereby automatically installing and disassembling the cylindrical shaft through the equipment, reducing the labor intensity of the staff and improving the production and processing efficiency.

[0034] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
