Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a constant pressure adaptive grinding device for curved metal surfaces. Background Technology

[0002] Metal surface polishing is an important process in metal processing. It is mainly used to remove defects such as burrs, oxide layers, and scratches caused by processing, so that the surface becomes smooth and flat, improving its surface quality and aesthetics. It also creates favorable conditions for subsequent processes such as coating and electroplating, ensuring the overall performance and appearance of metal products.

[0003] In the field of metal processing, there is a thorny problem when grinding existing curved metal surfaces: it is difficult to accurately control the contact pressure between the grinder and the curved metal surface. During the grinding process, it is difficult for operators to maintain the appropriate pressure by sight and touch. If the pressure is too low, the grinder cannot effectively remove the defects and unevenness of the metal surface; if the pressure is too high, it may excessively wear down the metal or even cause local dents. This uncontrollability of pressure control makes it difficult to achieve uniform grinding results, which seriously affects the quality and appearance of metal products and increases the risk and cost of subsequent rework. To address this, we propose a constant pressure adaptive grinding device for curved metal surfaces. Utility Model Content

[0004] One of the technical problems this application aims to solve is that the contact pressure between the grinding wheel and the curved metal surface is uncontrollable during grinding, making it difficult to achieve a uniform grinding effect.

[0005] To solve the above technical problems, this application provides a constant pressure adaptive grinding device for curved metal surfaces, including a base. The top of the base has a first groove, a second groove and a third groove. Four support columns are fixedly connected to the top of the base, and a top plate is fixedly connected to the top of the four support columns.

[0006] The detection unit is located on the top of the base. The detection unit includes a contact, a detection rod, and a detector. The contact cooperates with the detection rod and the detector to detect the curvature of the metal surface.

[0007] A grinding unit is disposed on the top of the base. The grinding unit includes a driving component and a grinding wheel. The driving component and the grinding wheel cooperate to grind the curved surface of the metal. The grinding unit cooperates with a detection unit for constant pressure adaptive grinding.

[0008] In some embodiments, the detection unit includes a first frame disposed at the top of a first groove, a first slider fixedly connected to the bottom of the first frame, the first slider slidably connected within the first groove, a first hydraulic rod fixedly connected to the outer side of the base, the drive end of the first hydraulic rod extending into the first groove and fixedly connected to the first slider, a detector fixedly connected to one side of the first frame, a detection rod slidably connected within the frame, one end of the detection rod extending out of the detector, and a connecting rod fixedly connected to the other end of the detection rod, with a contact element provided on one side of the connecting rod.

[0009] In some embodiments, the contact element includes a disc fixedly connected to one side of a first frame, a main rod extending through the disc, one end of the main rod extending through the first frame and fixedly connected to a connecting rod, and a limiting disc fixedly connected to the other end of the main rod. A contact wheel is rotatably connected to one side of the limiting disc, and three auxiliary rods are fixedly connected to the other side of the limiting disc. All three auxiliary rods extend through the disc and the first frame, and a spring is sleeved on the main rod.

[0010] In some embodiments, the contact elements are configured as three groups, and the main rods in the three groups of contact elements are all fixedly connected to the connecting rods.

[0011] In some embodiments, the grinding unit includes a second frame disposed at the top of the second groove, a second slider fixedly connected to the bottom of the second frame, the second slider being slidably connected within the second groove, a second hydraulic rod fixedly connected to the outer side of the base, the driving end of the second hydraulic rod extending into the second groove and fixedly connected to the second slider, a grinding wheel rotatably connected within the second frame, and a driving component disposed within the second frame.

[0012] In some embodiments, the drive unit includes a motor fixedly connected to the bottom of the second frame, a chain meshing with the drive end of the motor, a drive wheel meshing with one end of the chain, and the drive wheel being fixedly connected to the rotating end of the grinding wheel.

[0013] In some embodiments, a fixing unit is provided on the top of the base for clamping and fixing metal for polishing.

[0014] In some embodiments, the fixing unit includes a third slider slidably connected to a third groove, a base fixedly connected to the top of the third slider, a plurality of clamps fixedly connected to the top of the base, a third hydraulic rod fixedly connected to the outer side of the base, and the driving end of the third hydraulic rod extending into the third groove and fixedly connected to the third slider.

[0015] This utility model has at least the following beneficial effects:

[0016] Specifically, the detector detects the undulations of different locations on the sensing surface. Within a preset time, the detector continuously records the curvature of each contact point. This comprehensive curvature data reflects the local curvature characteristics of the surface.

[0017] Based on the collected curvature data, the system calculates and plots the surface curve using algorithms. This curve is not only a digital representation of the surface shape but also a key basis for subsequent grinding operations. The device drives the grinding unit to adjust its position according to the curve, ensuring that the grinding wheel can closely fit the surface contour. During the grinding process, since the grinding is performed based on the curvature of the metal surface, it will not deviate from the curvature. Therefore, the contact pressure between the grinding wheel and the metal surface remains constant. This process realizes a closed-loop operation from surface measurement to constant pressure grinding, ensuring high precision and consistency in metal surface grinding. Attached Figure Description

Example 1

[0025] Please see Figures 1-5 This utility model provides a technical solution:

Four support columns 24 are fixedly connected to the top of the base 1. A top plate 25 is fixedly connected to the top of the four support columns 24. It should be noted that the tops of the first frame 31 and the second frame 41 are slidably connected to the top plate 25 to enhance stability.

[0027] The detection unit 3 is located on the top of the base 1. The detection unit 3 includes a contact 37, a detection rod 35 and a detector 34. The contact 37 cooperates with the detection rod 35 and the detector 34 to detect the curvature of the metal surface.

[0028] Grinding unit 4 is located on the top of base 1. Grinding unit 4 includes driving component 45 and grinding wheel 44. Driving component 45 and grinding wheel 44 cooperate to grind the curved metal surface. Grinding unit 4 cooperates with detection unit 3 for constant pressure adaptive grinding.

[0029] The detection unit 3 includes a first frame 31 disposed at the top of the first groove 21, a first slider 32 fixedly connected to the bottom of the first frame 31, the first slider 32 slidably connected in the first groove 21, a first hydraulic rod 33 fixedly connected to the outside of the base 1, the driving end of the first hydraulic rod 33 extending into the first groove 21 and fixedly connected to the first slider 32, a detector 34 fixedly connected to one side of the first frame 31, a detection rod 35 slidably connected in the frame, one end of the detection rod 35 extending out of the detector 34, and a connecting rod 36 fixedly connected to the other end of the detection rod 35, and three sets of contact members 37, the main rod 372 in the three sets of contact members 37 being fixedly connected to the connecting rod 36, the connecting rod 36 being used to connect the three sets of contact members 37 for easy unified movement;

[0030] A contact element 37 is provided on one side of the connecting rod 36. The contact element 37 includes a disc 371 fixedly connected to one side of the first frame 31. A main rod 372 is connected through the disc 371. One end of the main rod 372 passes through the first frame 31 and is fixedly connected to the connecting rod 36. The other end of the main rod 372 is fixedly connected to a limiting disc 373. A contact wheel 374 is rotatably connected to one side of the limiting disc 373. Three auxiliary rods 375 are fixedly connected to the other side of the limiting disc 373. All three auxiliary rods 375 pass through the disc 371 and the first frame 31. A spring 376 is sleeved on the main rod 372. By setting the spring 376, it can return to its original position in time. It should be noted that by setting the auxiliary rods 375, the auxiliary rods 375 can play a damping role to prevent the contact element 37 from repeatedly vibrating back. In addition, the auxiliary rods 375 will not contact the connecting rod 36 and will not interfere with its movement.

[0031] The grinding unit 4 includes a second frame 41 disposed at the top of the second groove 22, a second slider 42 fixedly connected to the bottom of the second frame 41, the second slider 42 slidably connected in the second groove 22, a second hydraulic rod 43 fixedly connected to the outside of the base 1, the driving end of the second hydraulic rod 43 extending into the second groove 22 and fixedly connected to the second slider 42, and a grinding wheel 44 rotatably connected inside the second frame 41.

The drive wheel 453 is fixedly connected to the rotating end of the grinding wheel 44.

[0033] In operation, the third hydraulic rod 54 is first activated to move the fixed unit 5 to the position of the detection unit 3. Then, the first hydraulic rod 33 is activated, which drives the first frame 31 to move, thereby causing the contact wheels 374 in the three sets of contact members 37 to contact the curved metal surface. Then, the third hydraulic rod 54 is activated again to move the metal at a constant speed. At this time, the contact wheels 374 and the main rod 372 in the contact members 37 will move adaptively with the curvature of the curved surface, synchronously driving the detection rod 35 to move. At the same time, the detector 34 records the value of the movement of the detection rod 35. The curvature of the metal surface is calculated through a preset calculation program. Then, the third hydraulic rod 54 is activated again to move the metal to the position of the grinding unit 4. Then, the second hydraulic rod 43 is driven by the detector 34 through numerical control to move the second frame 41. At the same time, the drive component 45 is activated to drive the grinding wheel 44 to rotate. The grinding wheel 44 contacts the metal surface for grinding. Meanwhile, the third hydraulic rod 54 drives the metal to move again, while the second hydraulic rod 43 is driven along the detected curvature, thus coordinating to perform constant pressure grinding along the metal surface.
