Description

Technical Field

[0001] This application relates to the field of grinding machine processing, and more specifically to a chip-blowing device for a grinding machine. Background Technology

[0002] Grinding machines are core equipment for the precision machining of shaft and rod components. They use high-speed rotating grinding tools to grind the surface of the workpiece to achieve the required dimensional accuracy and surface finish. During the grinding process, a large amount of fine metal chips and abrasive dust are generated. If these chips adhere to the workpiece surface or accumulate in the machining area, they will not only affect the grinding accuracy and surface quality, but may also scratch the machined surface, leading to a decrease in product yield. Therefore, timely and thorough cleaning of chips from the workpiece surface after the grinding process is a crucial step in ensuring machining quality.

[0003] Currently, common chip removal methods mostly involve manual handheld air gun blowing, which is labor-intensive, the chip removal effect is affected by the operator's experience, and uniformity and consistency are difficult to guarantee. Furthermore, manual operation poses safety hazards. Some automated solutions use fixed air nozzles, but their fixed positions make it difficult to adapt to the varying shapes of different sized shafts and workpieces, resulting in limited blowing coverage and potential chip removal blind spots. In addition, the above solutions are functionally limited, only completing the chip removal task and unable to directly perform online inspection of the workpiece's machining quality after chip removal. In actual production, chip removal and inspection are usually performed in separate steps, requiring the workpiece to move between different workstations, increasing auxiliary time and equipment occupancy costs. Therefore, there is an urgent need for a clamping and chip removal device that can efficiently remove chips and has online inspection capabilities to improve the automation level and production efficiency of grinding machines. Summary of the Invention

The external grinding machine includes a moving platform 10, a first clamping device (not shown) mounted on the moving platform 10, and a second clamping device 20 mounted on the moving platform 10. The first clamping device and the second clamping device 20 are spaced apart by a predetermined distance. Those skilled in the art should understand that the moving platform 10 is a conventional grinding machine moving platform with a mounting block at its bottom. A drive device is configured to cooperate with the mounting block, and the drive device is implemented as a lead screw and slider structure. That is, the slider is mounted on the mounting block, the lead screw cooperates with the slider, and the slider is driven by a drive motor to move on the lead screw, thereby moving the moving platform 10 left and right a predetermined distance. It is worth mentioning that the second clamping device 20 is a conventional ejector clamping device, that is, it has a retractable ejector rod, which moves back and forth manually. The first clamping device is a chuck device to fix the position of the parts. Since the ejector clamping device and the chuck device are conventional mechanisms, they will not be described in detail.

[0024] It should be noted that the top of the mobile platform 10 has a tooling table 11, on which the first clamping device and the second clamping device 20 are both mounted. The grinding tool of the grinding machine is located on one side of the tooling table 11. It should be noted that the tooling table 11, the first clamping device, the second clamping device 20 and the grinding tool are all set on the machine body 1, and the chip blowing device 30 is also set on the machine body 1. A guide rail 100 and a drive mechanism 110 set on the guide rail 100 are also set on the top of the machine body 1, wherein the drive mechanism 110 is implemented as a lead screw and slider mechanism.

[0025] Specifically, the grinding machine clamping and chip blowing device includes a chip blowing device 30, which includes a mounting block (not shown), a drive assembly 32, and a support assembly 33. The mounting block is disposed on the drive mechanism 110, and the drive assembly 32 is fixed to the top of the mounting block. The support assembly 33 is mounted on one end of the drive assembly 32. The drive assembly 32 is configured to move the support assembly 33 back and forth a predetermined distance, wherein the direction of movement of the support assembly 33 is perpendicular to the direction of movement of the moving platform 10. Specifically, the drive mechanism 110 is configured to move the mounting block along the direction of the guide rail 100. It should be noted that the drive assembly 32 has a telescopic rod 321, one end of which is fixedly connected to the support assembly 33. The drive assembly 32 can be implemented as a cylinder-driven mechanism to extend and retract the telescopic rod 321, thereby enabling the support assembly 33, which cooperates with the telescopic rod 321, to operate synchronously.

[0026] It should be noted that the structure of the frame assembly 33 is as follows: Figure 2 As shown, it includes a first connecting block 331, and the end of the telescopic rod 321 cooperates with the first connecting block 331 to drive the first connecting block 331 to move synchronously. The assembly method involves the first connecting block 331 having a connecting hole through which the telescopic rod 321 passes, and a limiting stop block being installed at the end of the telescopic rod 321 to fix the first connecting block 331 to the telescopic rod 321, with the limiting stop block threadedly connected to the telescopic rod 321.

[0027] Furthermore, the top of the first connecting block 331 has a guide protrusion 3311, and the frame assembly 33 also includes a first support block 332. The bottom of the first support block 332 has a sliding groove 3321, which cooperates with the guide protrusion 3311. In addition, the frame assembly 33 also includes a fixing block 333. One end of the fixing block 333 is fixedly connected to the first connecting block 331, and the other end is fixedly connected to the first support block 332 to limit the position of the first support block 332. It should be noted that a screw can be installed on one side of the first support block 332 to reduce the opening of the sliding groove 3321 by tightening the screw. At the same time, the fixing block 333 is installed on one side of the first support block 332 to limit the position of the first support block 332. The structure and connection method of the first support block 332 and the fixing block 333 are as follows. Figure 3 and 4 As shown. The first support block 332 mentioned above has an L-shaped structure.

[0028] Additionally, the frame assembly 33 further includes a second connecting block 334 and a second support block 335. The second connecting block 334 is mounted on the first support block 332 and located above the fixing block 333. One end of the second support block 335 is fixed to the second connecting block 334. The connection between the second connecting block 334 and the second support block 335 is implemented by screw fastening. The chip blowing device 30 further includes an air blowing assembly 40, and the other end of the second support block 335 cooperates with the air blowing assembly 40.

[0029] Specifically, the air blowing assembly 40 includes a housing 41, and the end of the second support block 335 is fixedly connected to the end of the housing 41 by means of screw fixing.

[0030] Specifically, the housing 41 has a cavity structure 411, and one end of the housing 41 has a protrusion 412. The protrusion 412 has a first mounting hole 4121, which communicates with the cavity structure 411. The end of the second support block 335 is located below the protrusion 412. In addition, the side of the housing 41 opposite to the protrusion 412 also has two spaced-apart second mounting holes 413, both of which communicate with the cavity structure 411. The cavity structure 411 is closed by an external cover plate.

[0031] Additionally, the air-blowing assembly 40 includes an air supply bracket 42, which is fixed within the cavity structure 411. One end of the air supply bracket 42 has an air inlet 421, and the other end has two air outlets 422. The two air outlets 422 pass through two second mounting holes 413 and are positioned externally. One end of an external hose is connected to the air inlet 421, and the other end extends out of the first mounting hole 4121 and cooperates with an external air supply device. Those skilled in the art should understand that the air supply bracket 42 has an air supply channel 423, meaning that gas enters from the air inlet 421 and exits through the air supply channel 423, exiting from the two air outlets 422 respectively. It is worth mentioning that the end of the air outlet 422 has an assembly cavity 4221, which is connected to the air supply channel 423. The air blowing assembly 40 also includes two positioning assemblies 43. One end of each positioning assembly 43 is installed in the assembly cavity 4221, and the other end is placed on the outside and arranged opposite to each other.

[0032] It should be noted that the externally located air outlet 422 also has an oblong groove 4222, which is a through hole and is perpendicular to the assembly cavity 4221. In addition, each positioning component 43 includes a connector 431, one end of which passes through the oblong groove 4222 and the assembly cavity 4221 and is placed on the side where the two air outlets 422 are opposite to each other, and the other end abuts against the side where the two air outlets 422 are close to each other.

[0033] Specifically, each positioning component 43 further includes a support rod 432 and a positioning element 433. One end of the support rod 432 is sleeved on the end of the connector 431, and the other end extends a predetermined distance away from the housing 41. Simultaneously, one end of the positioning element 433 is fastened to the end of the connector 431 and presses against the end of the support rod 432 to limit the position of the support rod 432. It should be noted that the positioning element 433 and the connector 431 are installed via a threaded connection, allowing the position of the positioning element 433 to be adjusted so that the end of the connector 431, away from the positioning element 433, is not pressed tightly against the air outlet 422, facilitating subsequent movement of the connector 431.

[0034] It should be noted that each of the positioning components 43 also includes a movable member 434, an elastic member 435, and a stop member 436. One end of the movable member 434 is placed in the corresponding air supply channel 423, and the other end is located in the assembly cavity 4221. The movable member 434 placed in the assembly cavity 4221 also has a first insertion hole 4341. The connecting member 431 is configured to pass through the first insertion hole 4341 so that the movable member 434 and the connecting member 431 can move synchronously. Specifically, when air is supplied to the air supply channel 423, the end of the movable member 434 placed in the air supply channel 423 is pressed, so that the movable member 434 moves a predetermined distance away from the air supply channel 423. At the same time, the connecting member 431 moves away from the housing 41, thereby driving the support rod 432 to move forward. Furthermore, both the elastic element 435 and the abutment element 436 are placed within the assembly cavity 4221. One end of the elastic element 435 abuts against the end of the movable element 434, and the other end abuts against the abutment element 436. The abutment element 436 is fixed within the assembly cavity 4221 to define the position of the elastic element 435. That is, when the movable element 434 moves, the elastic element 435 is compressed; conversely, it is reset by moving the movable element 434. The abutment element 436 can be fixed by interference fit or welding.

[0035] It is worth mentioning that the end of the support rod 432 opposite to the air outlet end 422 also has a third mounting hole 4321 with an opening, and a fastening screw 4322 is also provided at the opening of the third mounting hole 4321, so that the third mounting hole 4321 is narrowed by tightening the fastening screw 4322, thereby limiting the component located in the third mounting hole 4321. Specifically, a jet rod 50 is installed at the third mounting hole 4321 of the upper support rod 432. The jet rod 50 has an air inlet and an air outlet. The air blowing assembly 40 also includes an air guide frame 44 and a connecting pipe 45. One end of the air guide frame 44 is installed on the air supply bracket 42, and the other end extends out of the housing 41 and is placed in the air supply bracket 42. Externally, one end of the connecting pipe 45 cooperates with the externally placed air guide frame 44, and the other end is installed at the air inlet of the jet rod 50. That is, when air is supplied into the air supply channel 423, the gas passes through the air supply channel 423, the air guide frame 44, the connecting pipe 45 and the jet rod 50 in sequence, and is discharged from the air outlet of the jet rod 50. That is, those skilled in the art should understand that the jet rod 50 is set to face the surface of the shaft workpiece and is located on one side of the grinding tool. That is, after the shaft workpiece is processed, the grinding tool retracts a predetermined distance. At this time, the drive mechanism 110 drives the mounting block to move along the direction of the guide rail 100 so as to cut and blow off the surface of the shaft workpiece through the jet rod 50, and then the air is cut off.

[0036] It should also be noted that a detection rod 60 is installed at the third mounting hole 4321 of the lower support rod 432, and the length of the lower support rod 432 is greater than the length of the upper support rod 432. That is, when air is supplied, the air jet rod 50 is facing the shaft workpiece, and the detection rod 60 is misaligned with the shaft workpiece. After the chip blowing is completed, the air jet rod 50 is misaligned with the shaft workpiece, and the detection rod 60 is facing the shaft workpiece. At the same time, the aforementioned drive mechanism 110 operates in the reverse direction to move the mounting block in the reset direction, thereby detecting the straightness of the shaft workpiece through the detection rod 60. In addition, the detection rod 60 can be implemented as any instrument or meter that can detect the straightness of the shaft workpiece.

[0037] It is worth mentioning that, in the embodiments of this application, the grinding machine clamping and chip blowing device has a simple structure, does not involve complex manufacturing processes or expensive materials, and has high economic efficiency. At the same time, for manufacturers, the grinding machine clamping and chip blowing device provided in this application is easy to produce and has low cost, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0038] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from these principles.
