Description

Technical Field

[0001] The invention relates to the technical field of metal surface treatment, in particular to a grinding device and method for a metal surface treatment system. Background Art

[0002] Metal surface treatment is a series of processes used to improve the surface properties of metals, including cleaning, pretreatment, coating of protective layers and other steps. These steps can improve the corrosion resistance, wear resistance, aesthetics and bonding strength of metals with other materials. In particular, some metals, such as molybdenum targets, are prone to form oxide films on the surface after being placed naturally, so it is generally necessary to remove the oxide film coating on the surface before use. The removal method is generally physical removal, that is, first grinding and then sandblasting, and then repeating the grinding several times to ensure complete removal.

[0003] In the prior art, the grinding methods for cylindrical metal parts such as molybdenum rods are all through general clamping and fixing methods, and then surface grinding. Most of them will be ground in a direction tangential to the axis of the material rod. This grinding method has high requirements for the clamping fixture, especially when the material rod is too long, the tangential grinding force is easy to cause the material rod to slip and the clamping to loosen, resulting in poor grinding effect; a small number of them use the method of grinding along the axis of the material rod to reduce the tangential rotational force received by the material rod, but this grinding method is inconvenient to operate, and it is necessary to perform a slight rotation after each grinding to grind in another angle direction. The rotation angle is inconvenient to control, and the grinding position is easy to deviate after the rotation angle, resulting in incomplete grinding.

[0004] Therefore, there is an urgent need for a grinding device and an operating method for conveniently grinding cylindrical metal parts to achieve a thorough and good metal surface grinding effect. Summary of the invention

DETAILED DESCRIPTION

[0045] In order to make the objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0048] Example 1

[0049] Reference Figure 1-Figure 7, which is the first embodiment of the present invention, provides a grinding device for a metal surface treatment system, which can prevent cylindrical metal parts from slipping and loosening due to the grinding force during grinding. It includes: a fixing component 100, a positioning component 200 and a grinding component 300. The grinding position can be adjusted by the positioning component 200, the cylindrical metal parts can be limited and fixed by setting the fixing component 100, and the grinding is completed by setting the grinding component 300.

[0050] Specifically, the fixing assembly 100 includes a workbench 101, a clamping portion 102 disposed on the top of the workbench 101 and used to prevent the cylindrical metal piece from rotating along the central axis, and a limiting portion 103 disposed on the top of the workbench 101 and used to prevent the cylindrical metal piece from moving in at least one direction along the central axis. The positioning assembly 200 is disposed on the top of the workbench 101, and includes a positioning box 201 disposed on the top of the workbench 101, a grinding notch 202 disposed on the top of the positioning box 201, a loading port 203 disposed on both sides of the positioning box 201 and capable of accommodating the cylindrical metal piece to enter and exit, and a positioning portion 204 disposed inside the positioning box 201 and used to push the cylindrical metal piece toward the grinding notch 202, wherein the grinding notch 202 is a strip groove, and its direction is adapted to the axial direction of the cylindrical metal piece.

[0051] Among them, the grinding assembly 300 is arranged on the top of the positioning box 201, including a grinder 301 installed on the top of the workbench 101 and adapted to the grinding notch 202. When the grinding wheel of the grinder 301 grinds the cylindrical metal part through the grinding notch 202, the direction of the tangential force F1 applied by the grinding wheel to the cylindrical metal part is parallel and opposite to the direction of the blocking force F2 of the limiting part 103 on the cylindrical metal part. In this way, there is direct blocking by the support roller 1 204b and the clamping part 102 in the vertical direction, and direct blocking by the limiting part 103 in the axial direction, so that the cylindrical metal part will not slip or deflect due to the grinding force. In this embodiment, each group of support rollers 1 204b includes two parts symmetrically arranged at the center of the grinding notch 202, so as to provide stable support for cylindrical metal parts of different diameters.

[0052] Furthermore, the positioning part 204 includes a telescopic member 204a disposed longitudinally at the bottom of the positioning box 201, a supporting roller 204b disposed at the output end of the telescopic member 204a, a flexible pad 204c disposed on the inner wall of the top of the positioning box 201, and a pushing member 204d disposed in the positioning box 201 and pushing the cylindrical metal member to a direction parallel to the center axis and the grinding notch 202. In this embodiment, the telescopic member 204a is an electric telescopic rod, and when the telescopic member 204a is activated, the supporting roller 204b can drive the cylindrical metal member to rise, thereby making the cylindrical metal member close to the grinding notch 202 above, and the flexible pad 204c is made of elastic material, which has the effect of buffering and reducing wear.

[0053] Among them, there are at least two groups of pushing members 204d, and the interval between two adjacent groups of pushing members 204d is not less than the minimum length of the cylindrical metal member. Each group of pushing members 204d includes two groups of pushing rods 204e symmetrically arranged on the inner wall of the positioning box 201, and the pushing rods 204e are rotatably connected to the inner wall of the positioning box 201 through a rotating shaft; the pushing rods 204e are divided into a pressing section 204e-1 and a driving section 204e-2 connected as one body by the rotating shaft, and an anti-slip pad 204e-3 for squeezing the cylindrical metal member is provided on one side of the pressing section 204e-1, and a driving member 204f is also provided at the bottom of the positioning box 201 for pushing the driving section 204e-2 to rotate relative to the rotating shaft. When the push rod 204e rotates relative to the inner wall of the positioning box 201 through the rotating shaft, the pressing section 204e-1 squeezes the cylindrical metal part through the anti-slip pad 204e-3 on one side. Since the pressing sections 204e-1 on both sides are symmetrical, the cylindrical metal part can be pushed to the grinding groove 202 in the middle position, which is convenient for adapting to cylindrical metal parts of different diameters.

[0054] Preferably, the driving member 204f includes a limit block 204f-1 slidably connected to the bottom of the positioning box 201, a limit groove 204f-2 penetrating the limit block 204f-1, a connecting shaft 204f-3 provided on one side of the driving section 204e-2 and adapted to the limit groove 204f-2, and a connecting rod 204f-4 connected between the limit blocks 204f-1 of different groups of push members 204d on the same side of the inner wall of the positioning box 201, and the positioning box 2 01 is provided with a driving motor 104f-5 on one side, and the output end of the driving motor 104f-5 is provided with a bidirectional threaded rod 204f-6 which is rotatably connected to the top of the workbench 101, and the connecting rod 204f-4 is threadedly connected to the bidirectional threaded rod 204f-6, and the threaded connection directions of the connecting rods 204f-4 and the bidirectional threaded rod 204f-6 on both sides are opposite, and the axial direction of the bidirectional threaded rod 204f-6 is parallel to the sliding direction of the limit block 204f-1. When the telescopic member 104a is started, the driving motor 104f-5 is also started, so that the bidirectional threaded rod 204f-6 rotates and drives the connecting rods 204f-4 on both sides to slide in the back direction, and the limit block 204f-1 follows the connecting rod 204f-4 to slide relative to the bottom of the positioning box 201, and then pushes the connecting shaft 204f-3 and the driving section 204e-2 through the limit groove 104f-2, and then the push rod 204e generates a driving force.

[0055] Working principle: insert the cylindrical metal piece to be polished into the positioning box 201 from the loading port 203 on one side of the positioning box 201, and move the end of the cylindrical metal piece out at the loading port 203 on the other side until it is blocked by the limiting part 103, and then lower the cylindrical metal piece to be temporarily supported between two adjacent groups of supporting rollers 204b, and at the same time make the cylindrical metal piece at least cover the interval between two adjacent groups of pushing members 204d; then start the telescopic member 204a, so that the supporting roller 204b drives the cylindrical metal piece to rise, so that the cylindrical metal piece is close to the polishing slot 202 above;

[0056] When the telescopic member 204a is started, the driving motor 204f-5 is also started, so that the bidirectional threaded rod 204f-6 rotates and drives the connecting rods 204f-4 on both sides to slide in the back direction, and the limit block 204f-1 follows the connecting rod 204f-4 to slide relative to the bottom of the positioning box 201, and then pushes the connecting shaft 204f-3 and the driving section 204e-2 through the limit groove 204f-2, so that the pushing rod 204e rotates relative to the inner wall of the positioning box 201 through the rotating shaft, and then the pressing section 204e-1 squeezes the cylindrical metal part through the anti-slip pad 204e-3 on one side. 04e-1 is symmetrical, so the cylindrical metal part can be pushed to the grinding groove 202 in the middle position, and finally the cylindrical metal part squeezes the flexible pad 204c on the top inner wall of the positioning box 201, and is fixed by the clamping part 102, and then the grinder 301 is started, so that the grinding force applied by the grinding wheel of the grinder 301 to the cylindrical metal part is parallel to the axial direction of the cylindrical metal part. Since there are direct obstructions of the support roller 204b and the clamping part 102 in the vertical direction and direct obstructions of the limiting part 103 in the axial direction, the cylindrical metal part will not slip or deflect due to the grinding force.

[0057] Example 2

[0058] Reference Figure 1-Figure 11 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a moving part 302, a tangential adjustment part 303 and an axial adjustment part 304, which solves the problems of inconvenient operation and incomplete grinding during grinding.

[0059] Specifically, the grinding assembly 300 also includes a moving part 302 arranged on the top of the positioning box 201, and the moving part 302 is used to drive the grinder 301 to move along the axial direction of the cylindrical metal part. It includes a slider 302a arranged at the bottom of the grinder 301 and located on both sides of the grinding groove 202, a slide rail 302b parallel to the axial direction of the cylindrical metal part and arranged on the top of the positioning box 201, and a reciprocating screw 302c rotatably connected to one end of the slide rail 302b, the slider 302a is slidably connected to the slide rail 302b, the slider 302a and the reciprocating screw 302c are threadedly slidably, and the reciprocating screw 302c is driven by a motor. The reciprocating screw 302c is driven by a motor to rotate, so that the grinder 301 moves back and forth along the slide rail 302b through the slider 302a, thereby achieving complete grinding of the cylindrical metal parts located in the positioning box 201 in the length direction, and the grinding direction is a straight line, which is relatively stable and not easy to deviate.

[0060] Furthermore, the limiting portion 103 includes a telescopic member 103a longitudinally arranged on the top of the workbench 101, a support frame 103b arranged at the output end of the telescopic member 103a, a limiting plate 103c arranged on one side of the support frame 103b, and an anti-slip pad 103d arranged on one side of the limiting plate 103c and adapted to the end of the cylindrical metal member; in this embodiment, the telescopic member 103a is also an electric telescopic rod. In the initial position, the cylindrical metal member is inserted into the positioning box 201 from the loading port 203 on one side of the positioning box 201, and the end of the cylindrical metal member is moved out at the loading port 203 on the other side until it is blocked by the limiting plate 103c, and the anti-slip pad 103d is squeezed and deformed to buffer and reduce the wear of the limiting plate 103c.

[0061] It is worth noting that when changing to a cylindrical metal piece of a different diameter, the stroke of the telescopic piece 1 204a for adjusting the initial lowest position is twice the stroke of the telescopic piece 2 103a. This is because the adjustment stroke distance of the telescopic piece 1 204a is the diameter difference of the two cylindrical metal pieces, while the adjustment stroke distance of the telescopic piece 2 103a is the radius difference of the two cylindrical metal pieces. After completing the initial position setting, the subsequent movement speeds of the telescopic piece 1 204a and the telescopic piece 2 103a are consistent, so that the central axis of the cylindrical metal piece and the center of the clamping portion 102 can always be kept in line during the upward movement of the cylindrical metal piece.

[0062] Among them, the clamping part 102 includes a connecting column 102a fixedly arranged at the center of the limiting plate 103c, a guide groove 1 102b distributed in a circular array at the center of the connecting column 102a and no less than three groups on one side of the limiting plate 103c, a turntable 102c rotatably connected to one side of the connecting column 102a, and a guide groove 2 102d distributed in a circular array at the center of the connecting column 102a on one side of the turntable 102c, the number of the guide groove 2 102d and the guide groove 1 102b being the same and corresponding one to one; the guide groove 1 102b is a strip groove pointing to the center of the connecting column 102a, the guide groove 2 102d is an arc groove, and the distances from the two ends of the arc groove to the center of the connecting column 102a are different, a guide column 102e is provided between the guide groove 1 102b and the guide groove 2 102d, and a clamping block 102f is provided on the side of the guide column 102e close to the cylindrical metal part. Twist the extrusion sleeve 102a-1 on the surface of the connecting column 102a so that the clutch plate 102a-2 no longer presses the turntable 102c, and then rotate the turntable 102c so that the arc groove of the guide groove 2 102d squeezes the guide column 102e until it moves along the strip groove of the guide groove 1 102b toward the center of the connecting column 102a, until each group of clamping blocks 102f simultaneously clamps and fixes the cylindrical metal part at the center.

[0063] Furthermore, the grinding assembly 300 also includes a tangential adjustment part 303 arranged on the support frame 103b, and the tangential adjustment part 303 is used to adjust the grinding angle direction of the cylindrical metal part. It includes a second drive motor 303a installed on the support frame 103b, and the output end of the second drive motor 303a is connected to the connecting column 102a through a coupling. The surface of the connecting column 102a is threadedly connected with an extrusion sleeve 102a-1, and a clutch plate 102a-2 is fixedly connected between the extrusion sleeve 102a-1 and the turntable 102c. After the oxide film coating on the surface of the cylindrical metal part is polished in a certain angle direction, the telescopic part 204a and the driving motor 204f-5 are started in reverse to rotate until the cylindrical metal part is no longer clamped by the flexible pad 204c and the push rod 204e and is not subject to excessive friction resistance, but the cylindrical metal part is still limited by the clamping part 102. At this time, the clamping part 102 is driven by the driving motor 2 303a to rotate a small angle. The angle can be simply controlled by the program so that the cylindrical metal part of the corresponding radius rotates within the angle. The arc length of the cylindrical metal part rotates within the angle is compatible with the width of the polishing slot 202; then, after each angle direction is polished, it continues to rotate a constant small angle until it is completely polished by rotating 360°.

[0064] Preferably, the grinding assembly 300 also includes an axial adjustment portion 304 provided on the support frame 103b, the axial adjustment portion 304 is used to adjust the grinding position of the cylindrical metal part in the length direction, and includes a support column 304a provided on the support frame 103b, a limiting groove 304b extending through the surface of the support column 304a, a tooth plate 304c slidably connected in the limiting groove 304c and parallel to the axial direction of the cylindrical metal part, a support roller 304d provided on the inner wall of the limiting groove 304b, and a slide rail 304e provided on the side of the tooth plate 304c and adapted to the support roller 304d, the top of the support frame 103b is rotatably connected to a driving gear 304f adapted to the tooth plate 304c, and the driving motor 303a is installed on one side of the tooth plate 304c. In the length direction of the cylindrical metal part, the tooth plate 304c can be moved axially along the limiting groove 304b by rotating the driving gear 304f, thereby adjusting the position of the cylindrical metal part relative to the positioning box 201. During grinding, the rotating shaft of the driving gear 304f can be squeezed and fixed by a threaded sleeve to prevent the blocking effect of the limiting plate 103c from being weakened.

[0065] The rest of the structure is the same as that of Example 1.

[0066] Working principle: In the initial position, insert the cylindrical metal piece into the positioning box 201 from the loading port 203 on one side of the positioning box 201, and move the end of the cylindrical metal piece out at the loading port 203 on the other side until it is blocked by the limit plate 103c, and the center of the clamping part 102 is exactly in line with the central axis of the cylindrical metal piece. Then drive the telescopic part 1 204a and the telescopic part 2 103a to move upward at the same moving speed, so that the central axis of the cylindrical metal piece is always in line with the center of the clamping part 102 during the upward movement of the cylindrical metal piece;

[0067] When the cylindrical metal piece is pushed to the middle grinding notch 202 by the push rods 204e on both sides and is moved to clamp the flexible pad 204c on the top inner wall of the positioning box 201, the extrusion sleeve 102a-1 on the surface of the connecting column 102a can be twisted first, so that the clutch plate 102a-2 no longer presses the turntable 102c, and then the turntable 102c is rotated, so that the arc groove of the guide groove 2 102d squeezes the guide column 102e to move along the strip groove of the guide groove 1 102b toward the center of the connecting column 102a, until each group of clamping blocks 102f simultaneously clamps and fixes the cylindrical metal piece at the center;

[0068] Then, the reciprocating screw 302c is driven by the motor to rotate, so that the grinder 301 moves back and forth along the slide rail 302b through the slider 302a, thereby achieving complete grinding of the cylindrical metal part located in the inner part of the positioning box 201 in the length direction, and the grinding direction is a straight line, which is relatively stable and not easy to deviate; in a certain angle direction, when the oxide film coating on the surface of the cylindrical metal part is polished, the telescopic part 204a and the driving motor 204f-5 are started in the reverse direction to rotate until the cylindrical metal part is no longer The cylindrical metal piece is clamped by the flexible pad 204c and the push rod 204e and is subjected to excessive friction resistance, but the cylindrical metal piece is still limited by the clamping part 102. At this time, the clamping part 102 is driven by the second driving motor 303a to rotate a small angle. The angle can be simply controlled by a program so that the cylindrical metal piece of the corresponding radius rotates within the angle so that the arc length of the cylindrical metal piece is matched with the width of the grinding notch 202; and then after each angle direction is polished, it continues to rotate a constant small angle until it is completely polished by rotating 360°.

[0069] In the length direction of the cylindrical metal part, the tooth plate 304c can be moved axially along the limiting groove 304b along the cylindrical metal part by rotating the driving gear 304f, thereby adjusting the position of the cylindrical metal part relative to the positioning box 201. During grinding, the rotating shaft of the driving gear 304f can be squeezed and fixed by the threaded sleeve to prevent the blocking effect of the limiting plate 103c from being weakened. By adjusting the position of the cylindrical metal part relative to the positioning box 201, after the surface of the cylindrical metal part except the end near the clamping part 102 is completely polished, the clamping and fixing of the cylindrical metal part is released, and then the other end of the cylindrical metal part is inserted through the positioning box 201 and then clamped and fixed by the clamping part 102 to complete the grinding of the remaining part. The above scheme can be used to perform deeper grinding of the oxide layer on the metal surface. The deeper the grinding depth, the greater the resistance, and the more significant the effect of the device of this scheme. After the initial grinding is completed by using this device, a shallower finishing grinding is performed in the traditional direction tangential to the axis of the material rod using an ordinary grinding device. This completely solves the problem of the difficulty in removing the surface oxide film coating, and ensures that the shaped metal parts maintain the arc surface.
