It is mainly used to grind high-precision planes, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other surfaces in the workpiece.

[0003] The existing air gap grinder is generally a single-sided air gap grinder, and it is not convenient to perform air gap grinding and plane grinding continuously, and the processing efficiency needs to be improved. In response to the above technical problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent publication number CN217194666U. When in use, the surface of the material is ground by a flat grinding chassis, and then two sets of air gap grinding wheels are used to perform air gap grinding on the ground surface.

When the height of the air gap grinding wheel is subsequently adjusted, the surface of the material cannot be positioned, and it is difficult to determine the depth of the air gap, resulting in inaccurate depth of air gap grinding and poor quality of air gap grinding.

[0011] Further technical solution: A second telescopic member is fixedly installed on the horizontal section of the bracket, and the second telescopic member drives the limit frame to move. The limit frame is a U-shaped structure and is used to limit the position of the lifting frame.

[0012] Further technical solution: the air gap grinding assembly includes a mounting frame, which is an L-shaped structure and is arranged on a positioning frame, and a third telescopic member that drives the mounting frame to move is fixedly installed on the positioning frame.

[0013] Further technical solution: The vertical section of the mounting frame is rotatably mounted with a transmission rod, the cross-section of the transmission rod is a non-circular structure and a second rotating power component that drives the transmission rod to rotate is fixedly mounted on the mounting frame, and two sets of spaced-apart air gap grinding discs are arranged on the transmission rod.

After the detection is completed, the detection component will limit the positioning frame from above to prevent the positioning frame from moving upward, so that the positioning frame is at a stable height to ensure the stability of the air gap grinding.

[0020] 3. Since the two sets of air gap grinding discs are on the same set of transmission rods, the two sets of air gap grinding discs are at the same height, and the height of the two sets of air gap grinding discs can be adjusted simultaneously, thereby ensuring that the depth of the two sets of air gaps subsequently ground is the same, ensuring the consistency of air gap grinding, and improving the quality of air gap grinding.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1-Figure 5 As shown, a planar double air gap through-type grinder provided by the present invention comprises a base 1, a placement plate 3 is slidably mounted on the base 1, a screw servo module 2 for driving the placement plate 3 to move is arranged on the base 1, and a clamping module 4 for clamping materials is arranged on the placement plate 3;

[0030] A top plate 5 is provided on the base 1, and a first telescopic member 6 is fixedly installed on the base 1 to drive the top plate 5 to move up and down. A first rotating power member 7 is fixedly installed on the surface of the top plate 5 close to the base 1, and the first rotating power member 7 drives the flat grinding disc 8 to rotate;

[0031] A positioning frame 10 is arranged on the top plate 5, and two groups of positioning plates 11 are slidably installed in the positioning frame 10. A first threaded rod 13 is rotatably installed in the positioning frame 10 to drive the two groups of positioning plates 11 to move in opposite directions at the same time. The positioning plates 11 are rotatably installed with multiple groups of balls 12 close to the surface of the base 1. A detection component 31 for detecting the position of the positioning frame 10 is arranged on the top plate 5, and an air gap grinding component 32 is arranged on the positioning frame 10.

[0032] In actual application of this embodiment, the material is placed on the placement plate 3 so that its air gap surface faces upward and is fixed by the clamping module 4. According to the depth and position of the air gap grinding, the two groups of positioning plates 11 are driven to move simultaneously by the first threaded rod 13, so as to avoid the positioning plates 11 blocking the position of the air gap grinding. Then, the height of the air gap grinding assembly 32 is adjusted. After the adjustment is completed, the placement plate 3 is driven to move horizontally by the screw servo module 2. At this time, the first telescopic member 6 drives the top plate 5 to move downward, and the flat grinding disc 8 is driven to rotate by the first rotating power member 7 so that the flat grinding disc 8 moves downward and contacts the upper surface of the material for grinding. The placement plate 3 continues to move driven by the screw servo module 2. When the positioning frame 10 is in the lowest position, the lowest position of the ball 12 is slightly lower than the grinding plane of the flat grinding disc 8, and the ball 12 is in contact with the flat grinding disc 8, so that the material after the upper surface grinding is completed contacts with the ball 12 and pushes the positioning frame 10 to move upward, and then the ball 12 can roll on the upper surface of the material. At this time, the detection component 31 can detect whether the ball 12 is in contact with the upper surface of the material, ensuring that the ball 12 is in contact with the upper surface of the material to achieve positioning of the upper surface of the material, thereby ensuring the accuracy of the depth during subsequent air gap grinding. After the detection is completed, the detection component 31 will limit the positioning frame 10 from above, thereby preventing the positioning frame 10 from moving upward, so that the positioning frame 10 is at a stable height, and then the placement plate 3 drives the material to continue to move, so that the air gap grinding component 32 can perform air gap grinding on the upper surface of the material. After the grinding is completed, the clamping module 4 releases the fixation of the material, and then the placement plate 3 is reset to continue the air gap grinding operation.

[0033] In an example of the present embodiment, the first rotating power component 7 is a first motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The first motor drives the flat grinding disc 8 to rotate, thereby grinding the upper surface of the material. The first telescopic component 6 is a first electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The first electric telescopic rod drives the top plate 5 to move up and down, thereby adjusting the height of the flat grinding disc 8.

[0034] like Figure 1-Figure 3 As shown, a flat double air gap through-type grinder provided by the present invention is provided, wherein a lifting frame 9 is slidably mounted on a top plate 5, the lifting frame 9 is a U-shaped structure, the lifting frame 9 passes through the top plate 5 and the end of the lifting frame 9 is fixedly connected to a positioning frame 10, and the moving tracks of the positioning frame 10 and the ball 12 pass through the grinding plane of the flat grinding disc 8.

[0035] Specifically, the detection component 31 includes a bracket 14, which is an L-shaped structure and is fixedly installed on the top plate 5. A pressure sensor 16 is fixedly installed on the horizontal section of the bracket 14, and a slide plate 15 is slidably installed on the vertical section of the bracket 14. An elastic member 17 is fixedly installed on the slide plate 15, and the end of the elastic member 17 away from the slide plate 15 is fixedly connected to the lifting frame 9.

[0036] Specifically, a second telescopic member 18 is fixedly installed on the horizontal section of the bracket 14 , and the second telescopic member 18 drives a limiting frame 19 to move. The limiting frame 19 is a U-shaped structure and is used to limit the position of the lifting frame 9 .

[0037] In actual application of this embodiment, when the lifting frame 9 is in the lowest position, the side of the ball bearing 12 close to the base 1 is slightly lower than the grinding plane of the flat grinding disc 8, and the slide plate 15 is in contact with the pressure sensor 16 but without pressure. When the flat grinding disc 8 finishes grinding the upper surface of the material, the material moves to the rear side. At this time, the material contacts the ball bearing 12. Since the side of the ball bearing 12 close to the base 1 is slightly lower than the grinding plane of the flat grinding disc 8, the material will push the positioning frame 10 upward through the ball bearing 12, so that the ball bearing 12 can roll on the upper surface of the material. At this time, the ball bearing 12 The upper surface of the material can be positioned, and the air gap grinding component 32 is installed on the positioning frame 10, so it is only necessary to adjust the height of the air gap grinding component 32 according to the positioning frame 10 and the ball 12. The position of the upper surface of the material determined by the ball 12 can provide a determined position for the height adjustment of the air gap grinding component 32, so that the air gap grinding component 32 can be quickly moved to an accurate grinding height, and the height positioning of the air gap grinding component 32 is realized. When the upper surface of the material moves to the position of the air gap grinding component 32, the air gap can be directly ground, ensuring the accurate grinding depth of the air gap;

[0038] The positioning frame 10 drives the lifting frame 9 to move upward. The upward movement of the lifting frame 9 will compress the elastic member 17 and generate pressure on the pressure sensor 16. The deformation of the elastic member 17 can be calculated through the pressure value of the pressure sensor 16. The deformation of the elastic member 17 is the distance that the lifting frame 9 is raised. When the flat grinding disc 8 is not worn, when the ball 12 is at the lowest position, the distance between its lowest surface and the lower surface of the flat grinding disc 8 is determined by a fixed value. If the fixed value is the same as the calculated deformation of the elastic member 17, it means that the positioning of the positioning ball 12 is accurate and there is no error. If the fixed value is smaller than the calculated deformation of the elastic member 17, since the ball 12 and the material are in rolling friction, the ball 12 There is almost no wear. If there is a difference, it means that the flat grinding disc 8 is worn. The wear height is the difference between the two. The indication of the pressure sensor 16 shows that the ball 12 is in contact with the upper surface of the material, ensuring that the ball 12 can position the upper surface of the material to avoid positioning errors caused by the ball 12 hanging in the air. By calculating the deformation of the elastic member 17, auxiliary detection of the position of the ball 12 after contact with the material is achieved. At the same time, calculating the deformation of the elastic member 17 can detect the wear of the flat grinding disc 8. The larger the deformation of the elastic member 17, the more severe the wear of the flat grinding disc 8, so as to remind the staff to replace the worn flat grinding disc 8 in time to ensure the grinding quality of the upper surface of the material, thereby improving the quality of air gap grinding.

[0039] When the ball 12 contacts the upper surface of the material, the second telescopic member 18 drives the limit frame 19 to move downward so that the end of the limit frame 19 contacts the upper surface of the lifting frame 9, and the limit frame 19 limits the lifting frame 9 from continuing to move upward. Then, the limit frame 19 cooperates with the material to make the positioning frame 10 at a fixed height, thereby ensuring that the height of the air gap grinding assembly 32 is in a fixed state during air gap grinding, thereby ensuring the quality of air gap grinding.

[0040] In one example of the present invention, the second telescopic member 18 is a second electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The second electric telescopic rod drives the limit frame 19 to move, thereby realizing the limitation of the lifting frame 9. The elastic member 17 is a spring, and of course it can also be other elastic components such as an elastic ball. The deformation of the spring can generate pressure on the pressure sensor 16.

[0041] like Figure 1-Figure 4 As shown, a planar double air gap through-type grinder provided by the present invention, the air gap grinding assembly 32 includes a mounting frame 21, the mounting frame 21 is an L-shaped structure and is arranged on a positioning frame 10, and a third telescopic member 20 is fixedly installed on the positioning frame 10 to drive the mounting frame 21 to move.

[0042] Specifically, a transmission rod 22 is rotatably mounted on the vertical section of the mounting frame 21 . The cross section of the transmission rod 22 is a non-circular structure and a second rotating power member 23 that drives the transmission rod 22 to rotate is fixedly mounted on the mounting frame 21 . Two sets of air gap grinding discs 26 are arranged at intervals.

[0043] Specifically, two sets of connecting tubes 24 are slidably installed on the transmission rod 22, and the air gap grinding disk 26 is slidably installed on the connecting tube 24. The connecting tube 24 is fixedly installed with a pad 25 for limiting the position of the air gap grinding disk 26, and the connecting tube 24 is threadedly connected with a fixing nut 27 for fixing the air gap grinding disk 26.

[0044] Specifically, two groups of second threaded rods 29 are rotatably installed on the vertical section of the mounting frame 21 , and the two groups of second threaded rods 29 respectively drive a group of connecting plates 28 to move. The two groups of connecting plates 28 correspond to the two groups of connecting tubes 24 , respectively, and the connecting plates 28 are rotatably connected to the connecting tubes 24 .

[0045] Specifically, a fixing block 30 is slidably mounted on the horizontal section of the mounting frame 21 , and two groups of second threaded rods 29 penetrate the fixing block 30 and are movably connected to the fixing block 30 .

[0046] In actual application of this embodiment, the positions of the two groups of positioning plates 11 are adjusted by the first threaded rod 13 according to the positions of the two groups of air gap grinding, and then the second threaded rod 29 is rotated, and the second threaded rod 29 adjusts the position of the connecting tube 24 through the connecting plate 28, thereby adjusting the position of the air gap grinding disc 26, and the two groups of air gap grinding discs 26 are respectively adjusted to the grinding position by the two groups of second threaded rods 29, and the ends of the second threaded rod 29 are supported by the fixing block 30, thereby increasing the stability of the second threaded rod 29 when in use, and the transmission rod 22 can be supported by the second threaded rod 29 and the connecting plate 28 during subsequent grinding, thereby preventing the transmission rod 22 from being bent by external forces during the grinding process, thereby improving the stability of the device in use;

[0047] When the air gap grinding disc 26 moves to the top, the distance between its lowest position and the lowest position of the ball 12 is a fixed value. During adjustment, the mounting frame 21 is driven downward by the third telescopic member 20 according to the depth of the air gap. The distance moved by the mounting frame 21 is the fixed value plus the air gap depth. At this time, the lowest point of the air gap grinding disc 26 exceeds the lowest position of the ball 12 downward, and the distance from the lowest point of the air gap grinding disc 26 to the lowest position of the ball 12 is the air gap depth. At this time, the position and height of the air gap grinding disc 26 are adjusted. Since the two groups of air gap grinding discs 26 are on the same group of transmission rods 22, it is ensured that the two groups of air gap grinding discs 26 are at the same height, thereby ensuring that the depths of the two groups of air gaps to be subsequently polished are the same, ensuring the consistency of the air gap polishing and improving the quality of the air gap polishing. The second rotating power member 23 drives the transmission rod 22 to rotate, and the transmission rod 22 drives the air gap grinding disc 26 to rotate through the connecting tube 24, and the rotating air gap grinding disc 26 performs air gap polishing on the material;

[0048] When the air gap grinding disc 26 needs to be replaced, the fixing block 30 is removed at this time, and then the second threaded rod 29 is rotated to remove the connecting tube 24 from the transmission rod 22. After that, the fixing nut 27 on the air gap grinding disc 26 can be released and the air gap grinding disc 26 can be removed and replaced. In this way, the air gap grinding disc 26 can be easily disassembled, which is convenient for subsequent maintenance and replacement, and improves the convenience of using the device.

[0049] In one example of the present invention, the second rotating power component 23 is a second motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The second motor drives the air gap grinding disc 26 to rotate through the transmission rod 22. The third telescopic component 20 is an electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The third electric telescopic rod drives the mounting frame 21 to move, thereby adjusting the height of the air gap grinding disc 26.

[0051] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
