Description

Technical Field

[0001] The invention relates to the technical field of grinding machines, in particular to a grinding machine with a feed correction function and a method thereof. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders and polishing machines. Grinding machines can process materials with higher hardness, such as hardened steel, cemented carbide, etc. Grinding machines can perform high-precision and very small surface roughness grinding, and can also perform high-efficiency grinding, such as high-power grinding.

[0003] There are many existing technologies for grinding machine devices, such as:

When the rubber roller rotates, the blowing assembly is driven to blow air on the surface of the workpiece.

[0014] As a further improvement of the present technical solution, the blowing assembly includes a rack slidably arranged on the inner wall of the movable frame, and when the half gear rotates, the rack is driven to move upward in a vertical direction. A reset rod is provided between the rack and the movable frame, an air pipe is provided above the rack, a piston push rod is provided on the inner wall of the air pipe, and a rotating nozzle is provided at the end of the air pipe.

[0015] As a further improvement of the technical solution, a return spring is provided at the bottom of the piston push rod and the air pipe to push the piston push rod to move in a vertical direction.

The second motor output end is controlled to drive the reciprocating screw rod to rotate, and a moving plate provided on the surface of the reciprocating screw rod moves relatively. A detection table provided on the top of the moving plate simultaneously detects the top and bottom of the workpiece. When the moving block moves horizontally to drive the detection table to move on the workpiece surface, the rotation direction of the top pin of the detection table can be observed, thereby avoiding the workpiece and the main shaft of the grinder from being out of center, thereby improving the grinding accuracy and efficiency.

[0024] In the grinder with feed correction function, the servo motor drives the rubber roller to rotate, so that the rubber roller fits the surface of the workpiece and rotates. Since the rubber roller is made of rubber material, there is a large friction force when it fits the surface of the workpiece and rotates, so that the workpiece clamped in the three-jaw chuck rotates, and the rubber roller is driven to move by the moving block, so that the surface of the workpiece is fully dusted, which reduces the operator's misjudgment of whether the clamping position of the workpiece is offset, thereby improving the detection efficiency.

[0025] In the grinding machine with feed correction function, the half gear rotates to drive the rack to move in the vertical direction, and the rack pushes the piston push rod to move, so that the piston push rod squeezes the air inside the air pipe, so that the air is ejected from the rotating nozzle, and the floating dust on the surface of the workpiece is quickly blown away, thereby improving the efficiency of blowing away the dust on the surface of the workpiece.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] One of the purposes of the present invention is to provide a grinding machine with a feed correction function, referring to Figure 1-Figure 8 As shown, it includes a body 100, a workbench 101 is provided on the surface of the body 100, a vertical plate 102 is provided on one side of the workbench 101, a telescopic rod 103 is provided on one side of the end of the vertical plate 102, a grinding head 104 is provided on the end of the telescopic rod 103, a slide plate 200 is slidably provided on the top of the workbench 101, a workpiece head frame is provided on the surface of the slide plate 200, a three-jaw chuck 201 is provided on the end of the workpiece head frame, a top seat 202 is provided on the side of the surface of the slide plate 200 away from the workpiece head frame, and a workpiece to be ground is clamped between the three-jaw chuck 201 and the top seat 202;

[0042] A mobile correction component 300 is provided on one side of the slide plate 200, and the mobile correction component 300 is used to correct the workpiece to be polished. A dust removal component 400 is provided inside the mobile correction component 300, and the dust removal component 400 is used to remove dust from the workpiece to reduce the influence of dust on the workpiece during the correction process of the mobile correction component 300. A blowing component 500 is provided on one side of the dust removal component 400, and the blowing component 500 is used to blow air on the surface of the workpiece after the dust removal by the dust removal component 400, so as to keep dust away from the surface of the workpiece.

[0043] The improvement of this embodiment is that: the servo motor 403 drives the rubber roller 404 to rotate, so that the rubber roller 404 rotates in contact with the surface of the workpiece. Since the rubber roller 404 is made of rubber material, there is a large friction force when it rotates in contact with the surface of the workpiece, so that the workpiece clamped in the three-jaw chuck 201 rotates, and the rubber roller 404 is driven to move by the moving block 303, so that the surface of the workpiece is fully dusted, which reduces the operator's misjudgment of whether the clamping position of the workpiece is offset, thereby improving the detection efficiency. The half gear 405 rotates to drive the rack 501 to move in the vertical direction. The rack 501 pushes the piston push rod 504 to move, so that the piston push rod 504 squeezes the air inside the air pipe 503, so that the air is ejected from the rotating nozzle 506, and the floating dust on the surface of the workpiece is quickly blown away, thereby improving the efficiency of blowing away dust on the surface of the workpiece.

[0044] In the process of clamping the workpiece, in order to avoid the workpiece clamping offset, resulting in dimensional deviation during the grinding process of the workpiece, affecting the use of the workpiece, the mobile correction component 300 includes a first motor 301 arranged on one side of the slide 200, the output shaft at the end of the first motor 301 is provided with a rotating screw 302, the surface of the rotating screw 302 is provided with a moving block 303 for horizontal movement, the end of the moving block 303 is provided with a dust removal component 400, the top of the moving block 303 is provided with a second motor 304, the output end of the second motor 304 is provided with a reciprocating screw 305, the surface thread of the reciprocating screw 305 is symmetrical, the surface of the reciprocating screw 305 is provided with a symmetrical moving plate 306, the surface of the moving plate 306 is provided with a detection table 307, the moving detection table 307 performs horizontal detection on the top and bottom of the workpiece at the same time, the surface of the moving plate 306 is provided with an electronic recognition device 308, the electronic recognition device 308 is used to monitor the recognition status of the detection table 307, when the workpiece is clamped between the three-jaw chuck 201 and the top seat 202, the rotating screw 302 is driven to rotate by the output end of the first motor 301, and the moving block 303 provided on the surface of the rotating screw 302 moves horizontally and reciprocatingly, and the output end of the second motor 304 is controlled to drive the reciprocating screw 305 to rotate, and the moving plate 306 provided on the surface of the reciprocating screw 305 moves relatively, and the detection table 307 provided on the top of the moving plate 306 simultaneously detects the top and bottom of the workpiece, when the moving block 303 moves horizontally and drives the detection table 307 to move on the workpiece surface, when the workpiece axis is at the same level as the first motor 301, the ejector pin of the detection table 307 remains unchanged during the movement, and when the clamping position of the workpiece is offset, the ejector pin of the detection table 307 will be irregularly offset and rotated due to different pressures, and the position offset is recorded by the electronic identification device 308, so as to adjust the workpiece so that its axis is at the same level as the first motor 301, so as to avoid dimensional deviation caused by the offset of the workpiece during the grinding process, thereby ensuring the grinding processing accuracy.

[0045] Considering that when dust adheres to the surface of the workpiece, the movement of the ejector pin of the detection gauge 307 on the surface of the workpiece is easily affected by the dust, which may cause the operator to misjudge the clamping angle stubbornly. Therefore, the dust removal component 400 includes a second cylinder 401 arranged on the side wall of the moving block 303, and a piston rod at the end of the second cylinder 401 is provided with a moving frame 402, and a servo motor 403 is provided on one side of the moving frame 402. A rubber roller 404 is provided on the output shaft at the end of the servo motor 403. Before correcting the workpiece, in order to remove the influence caused by dust adhering to the surface of the workpiece, a rubber roller 404 is provided at the end of the second cylinder 401. The piston rod of the part drives the moving frame 402 to move horizontally along the axial direction, and the servo motor 403 is started to drive the rubber roller 404 to rotate, so that the rubber roller 404 is in contact with the surface of the workpiece and rotates. Since the rubber roller 404 is made of rubber material, there is a large friction force when it is in contact with the surface of the workpiece and rotates, so that the workpiece clamped in the three-jaw chuck 201 is rotated, and the rubber roller 404 is driven to move by the moving block 303, so that the surface of the workpiece is fully dusted, which is convenient for improving the accuracy of the workpiece correction and reducing the operator's misjudgment of whether the clamping position of the workpiece is offset, thereby improving the detection efficiency.

[0046] When the rubber roller 404 is used to rub the surface of the workpiece for dust removal, in order to improve the dust removal efficiency, a groove is provided at the center of the rubber roller 404, a half gear 405 is provided in the groove, and a blowing assembly 500 is provided on the inner wall of the mobile frame 402. When the rubber roller 404 rotates, the blowing assembly 500 is driven to blow air on the surface of the workpiece. The blowing assembly 500 includes a rack 501 slidably arranged on the inner wall of the mobile frame 402. When the half gear 405 rotates, the rack 501 is driven to move upward in a vertical direction. A reset rod 502 is provided between the rack 501 and the mobile frame 402, an air pipe 503 is provided above the rack 501, and a piston push rod 50 is provided on the inner wall of the air pipe 503. 4. A rotating nozzle 506 is provided at the end of the air pipe 503. When the rubber roller 404 drives the half gear 405 to rotate coaxially, the half gear 405 drives the rack 501 to move in the vertical direction. Since a reset rod 502 is provided at the bottom of the rack 501, the half gear 405 drives the rack 501 to move back and forth in the vertical direction when it rotates. During the movement of the rack 501, the piston push rod 504 is pushed to move, so that the piston push rod 504 squeezes the air inside the air pipe 503, so that the air is ejected from the rotating nozzle 506 to quickly blow away the floating dust on the surface of the workpiece. At the same time, the blowing direction of the rotating nozzle 506 can be adjusted, thereby improving the efficiency of blowing away the dust on the surface of the workpiece.

[0047] Taking into account the different surface areas of the workpieces, in order to improve the efficiency of blowing away dust, it is necessary to blow air on the surface of the workpiece multiple times. Therefore, a return spring 505 is provided at the bottom of the piston push rod 504 and the air pipe 503 to push the piston push rod 504 to move in the vertical direction. When the piston push rod 504 stops pushing, the piston push rod 504 is reset by the force of the return spring 505. When the piston push rod 504 is pushed by the rack 501, the air inside the air pipe 503 is squeezed, so that the air blows the workpiece surface through the rotating nozzle 506. Since the rack 501 reciprocates under the force of the half gear 405, when the force of the rack 501 on the bottom of the piston push rod 504 disappears, the piston push rod 504 is reset by the force of the return spring 505, which is convenient for the next time the rack 501 squeezes and blows the piston push rod 504, thereby achieving multiple blowing of the loose dust on the workpiece, accelerating the rapid falling of the dust attached to the surface of the workpiece, and improving the cleaning efficiency of the workpiece surface.

[0048] In summary, the working principle of the present invention is as follows: by clamping one side of the workpiece on the inner wall of the three-jaw chuck 201, the top seat 202 is moved to support and fix the other side of the workpiece, and at the same time, the piston rod at the end of the first cylinder 205 is started to drive the base 206 to move in the vertical direction, so that the support roller 207 rotating on the inner wall of the base 206 supports the bottom of the workpiece, the output end of the first motor 301 drives the rotating screw 302 to rotate, and the moving block 303 provided on the surface of the rotating screw 302 moves horizontally, and the output end of the second motor 304 is controlled to drive the reciprocating The screw rod 305 rotates, and the moving plate 306 provided on the surface of the reciprocating screw rod 305 moves relatively. The detection table 307 provided on the top of the moving plate 306 detects the top and bottom of the workpiece at the same time. When the moving block 303 moves horizontally to drive the detection table 307 to move on the workpiece surface, when the axis of the workpiece and the three-jaw chuck 201 are at the same level, the ejector pin of the detection table 307 remains unchanged during the movement. When the clamping position of the workpiece is offset, the ejector pin is subjected to different pressures and will rotate irregularly. The position is detected by the electronic recognition device 308. The offset is recorded, so that the workpiece is adjusted so that its axis is at the same level with the three-jaw chuck 201, so as to avoid the deviation of the workpiece and cause dimensional deviation during the grinding process, so as to ensure the grinding processing accuracy. The servo motor 403 drives the rubber roller 404 to rotate, so that the rubber roller 404 rotates in contact with the surface of the workpiece. Since the rubber roller 404 is made of rubber, there is a large friction force when it rotates in contact with the surface of the workpiece, so that the workpiece clamped in the three-jaw chuck 201 rotates, and the rubber roller 404 is driven to move by the moving block 303. Thereby, the surface of the workpiece is completely dusted, which is convenient for improving the accuracy of workpiece correction and reducing the operator's misjudgment of whether the clamping position of the workpiece is offset, thereby improving the detection efficiency. The rack 501 moves in the vertical direction, pushing the piston push rod 504 to move, so that the piston push rod 504 squeezes the air inside the air pipe 503, and the air is ejected from the rotating nozzle 506 to quickly blow away the floating dust on the surface of the workpiece. At the same time, the blowing direction of the rotating nozzle 506 can be adjusted to improve the efficiency of blowing away dust on the workpiece surface.

[0049] When the axial length of the workpiece is long, its middle position is easily bent due to gravity, which affects the accuracy of the feeding detection process and causes the operator to misjudge the clamping position of the workpiece. Therefore, a tooth plate 203 is provided on the surface of the slide plate 200, and a tooth pattern seat 204 is provided above the tooth plate 203. The horizontal movement of the tooth plate 203 drives the tooth pattern seat 204 to mesh and rotate. A first cylinder 205 is provided on the top of the tooth pattern seat 204. A piston rod at the end of the first cylinder 205 is provided with a base 206. A support roller 207 is provided on the inner wall of the base 206. The support roller 207 is in contact with the bottom of the workpiece for support. The piston rod at the end of the first cylinder 205 pushes the base 206 along the vertical direction. The support roller 207 is rotated in the base 206 to support the center bottom of the workpiece, thereby reducing the bending of the workpiece due to gravity and affecting the feed correction judgment of the workpiece, thereby improving the feed correction efficiency. At the same time, since the surface of some workpieces is tapered, in order to make the support roller 207 fit the tapered surface, the tooth plate 203 is moved to make the tooth pattern seat 204 rotate in the horizontal direction, thereby adjusting the support angle of the support roller 207 on the bottom of the workpiece, so that the support roller 207 fits the workpiece closely, improves the support of the support roller 207 for different workpieces, avoids the bending of the longer middle part of the workpiece and affects the misjudgment of the horizontality of the workpiece, and improves the production grinding efficiency.

[0050] A second object of the present invention is to provide a grinding method with a feed correction function, comprising any one of the above-mentioned grinding machines with a feed correction function, comprising the following steps:

[0051] S1. Clamp one side of the workpiece on the inner wall of the three-jaw chuck 201, move the top seat 202 to support and fix the other side of the workpiece, and at the same time start the piston rod at the end of the first cylinder 205 to drive the base 206 to move in the vertical direction, so that the support roller 207 rotating on the inner wall of the base 206 supports the bottom of the workpiece;

[0052] S2, inspect and correct the workpiece surface by moving the correction component 300, and drive the dust removal component 400 to remove impurities from the workpiece surface during the movement of the correction component 300, so that the dust attached to the workpiece surface falls off, and the dust accumulation on the workpiece surface is reduced to affect the judgment of the mobile correction component 300 on the deviation of the workpiece clamping position;

[0053] S3. When the dust removal component 400 performs friction dust removal on the workpiece surface, the dust removal component 400 drives the blowing component 500 to blow the loose dust on the workpiece surface, thereby accelerating the falling of the dust attached to the workpiece surface;

[0054] S4. When the workpiece is corrected, the sliding plate 200 is moved on the surface of the machine body 100 so that the grinding head 104 grinds the moving workpiece.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
