[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 The utility model provides an embodiment: a high-precision CNC centerless grinder transfer device, including a grinder body 1, a support frame 2 is installed on the top of the grinder body 1 through an electric slide rail, a driving component 3 is installed on the top of the support frame 2, two electric telescopic rods 4 are arranged outside the driving component 3, the output ends of the two electric telescopic rods 4 are fixedly connected to a limiting plate 6, the bottom of the limiting plate 6 is fixedly connected to two support rods 7, the bottom of the limiting plate 6 is fixedly connected to a second motor 9, the output end of the second motor 9 is fixedly connected to a clamping component 8, and a dust removal component 5 is arranged outside the driving component 3.

[0025] Specifically, electric slide rails are installed at both ends of the grinder body 1, and the support frame 2 can move back and forth through the electric slide rails, thereby realizing the transportation of the processed parts. The support frame 2 supports the drive assembly 3, so that the drive assembly 3 moves more smoothly and the device runs more stably. The clamping assembly 8 is moved above the part through the drive assembly 3, and then the limit plate 6 is pushed to move by the electric telescopic rod 4, so that the clamping assembly 8 is close to the part, and the limit plate 6 fixes the second motor 9, so that the structure can run stably, and then the part is clamped by the clamping assembly 8 for convenient transportation. The two support rods 7 play a role in fixing and connecting the clamping assembly 8, so that it can work normally. At the same time, through the operation of CNC technology, the parts are clamped and transported more accurately.

[0026] Reference Figure 1 and Figure 2 The driving assembly 3 includes a first motor 301, which is fixedly connected to the outer top of the support frame 2. Two slide grooves 302 are provided on the top of the support frame 2. A threaded rod 303 is fixedly connected to the output end of the first motor 301. The outer thread of the threaded rod 303 is connected to a slider 304. The inner part of the other slide groove 302 is fixedly connected to a guide rod 305. The tops of the two electric telescopic rods 4 are fixedly connected to the bottom of the slider 304. The outer part of the guide rod 305 is slidably connected to the inner part of the slider 304, and one end of the threaded rod 303 is rotatably connected to the inner wall of the slide groove 302.

[0027] Specifically, by fixing the first motor 301 on the outer top of the support frame 2, the first motor 301 does not shake during operation, and the device runs more stably. Then, the first motor 301 drives the threaded rod 303 to rotate, so that one end of the slider 304 slides along the direction of the slide groove 302, and the other end is connected to the outside of the guide rod 305 for sliding, so that the slider 304 is more stable when moving. The guide rod 305 guides the movement of the slider 304, thereby driving the clamping assembly 8 to move above the part through the slider 304, and finally completing the part transfer operation.

[0028] Reference Figure 1 and Figure 3 The dust removal component 5 includes a sleeve 501, which is fixedly connected to the bottom of the slider 304. The piston 502 is slidably connected inside the sleeve 501, and the bottom of the piston 502 is fixedly connected to a connecting rod 503. Two one-way valves 504 are installed inside the sleeve 501, and the outside of the sleeve 501 is fixedly connected to an air outlet pipe 505; one end of the external air outlet pipe 505 of one of the one-way valves 504 is fixedly connected, and one end of the air outlet pipe 505 is fixedly connected to the outside of the mounting shell 801, and the other end of the connecting rod 503 is fixedly connected to the top of the limit plate 6.

[0029] Specifically, the sleeve 501 is fixed by the slider 304, so that when the piston 502 inside the sleeve 501 moves, the sleeve 501 will not move, so that air enters the interior of the sleeve 501 from one of the one-way valves 504, and when the electric telescopic rod 4 pushes the limit plate 6 to move, the connecting rod 503 drives the piston 502 to move, so that the interior of the sleeve 501 is filled with air, and when the electric telescopic rod 4 contracts, the air is discharged to the air outlet pipe 505 through the other one-way valve 504, and then the air is sprayed to the clamped parts through the nozzle at the other end of the air outlet pipe 505, thereby removing dust on the surface thereof, ensuring the accuracy of subsequent part processing and the quality of processing, wherein one end of the air outlet pipe 505 is fixed to the outside of the mounting shell 801, so that the air outlet pipe 505 does not shake when spraying air, and the dust removal effect is more stable.

[0030] Reference Figure 1 and Figure 4 The clamping assembly 8 includes a mounting shell 801, which is fixedly connected to the bottom ends of the two support rods 7. Four sliding rods 803 are fixedly connected inside the mounting shell 801, and the four sliding rods 803 are slidably connected to the outside of the limiting rod 805. The output end of the second motor 9 is fixedly connected to a rotating disk 802, and the outside of the rotating disk 802 is rotatably connected to four arc rods 804, one end of the arc rod 804 is rotatably connected to the outside of the limiting rod 805, and the top of the rotating disk 802 is rotatably connected to the inner top of the mounting shell 801.

[0031] Specifically, by fixing the mounting shell 801 at the bottom ends of the two support rods 7, the second motor 9 can drive the rotating disk 802 to rotate when running, thereby rotating the four arc rods 804, so that the four limit rods 805 can slide along the sliding rods 803 respectively, thereby realizing the clamping operation of the parts. The movement of the limit rods 805 can be guided by the multiple sliding rods 803, and the parts can be clamped by the multiple limit rods 805. At the same time, different types of parts can be clamped, which has a wider applicability and a better clamping effect, thereby completing the part transfer operation.

[0032] Working principle: When using this device, first start the electric slide rail to drive the support frame 2 to move, then use the first motor 301 to drive the threaded rod 303 to rotate, so that the slider 304 starts to slide along the direction of the slide groove 302, and at the same time, it moves more smoothly under the action of the guide rod 305, moves to the top of the parts that need to be transported, and then the two electric telescopic rods 4 push the limit plate 6 to move downward. At this time, the piston 502 inside the sleeve 501 moves downward under the action of the connecting rod 503, and the air enters the inside of the sleeve 501 from the one-way valve 504 installed on one side of the sleeve 501, and then start the second motor 9 to make the rotating disk 802 rotate. 02 drives the four arc rods 804 to rotate, and then the four limit rods 805 slide along the slide rod 803 respectively, so that the distance between them is reduced, and finally the processed parts are clamped, and then the electric telescopic rod 4 contracts, so that the piston 502 moves upward inside the sleeve 501, so that the air inside the sleeve 501 is discharged through the air outlet pipe 505, and sprayed to the parts through the nozzle installed at one end of the air outlet pipe 505, so as to remove the dust on the surface of the parts, thereby ensuring the quality of part grinding and the accuracy of part processing. Through the above steps, the transfer of parts on the grinding machine is finally realized, and the parts are sent to the grinding bin for processing.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
