Description

Technical Field

[0001] This utility model belongs to the technical field of roughness testing equipment, specifically relating to an adjustable roughness testing clamping device. Background Technology

[0002] Roughness inspection is a crucial inspection item for metal parts. Rough surfaces can increase friction, leading to faster wear, or compromise sealing, causing leaks. Furthermore, excessive roughness during assembly can prevent parts from fitting properly, and rough surfaces can also harbor microcracks, affecting fatigue life and reducing durability. When performing roughness inspection on metal parts, they typically need to be stably clamped before being probed by a roughness tester. Existing clamping mechanisms are usually simple grippers or positioning slots that embed or clamp the metal part before pushing it in front of the roughness tester. To facilitate pushing the part, a pusher rail is often added to the bottom of the clamping mechanism. This type of clamping mechanism can only push the fixed surface of the part towards the tester; the tester cannot inspect multiple positions of the part simultaneously, resulting in low inspection efficiency. Moreover, the clamping stability of existing mechanisms is poor, failing to securely hold irregularly shaped parts, thus affecting inspection accuracy. Utility Model Content

[0003] To address the aforementioned problems and technical requirements, this utility model provides an adjustable roughness detection clamping device. This device can securely clamp metal parts of different shapes and can detect multiple positions of metal parts at once. It has the advantages of convenient operation and high detection efficiency.

[0004] The technical solution of this utility model is as follows: An adjustable roughness testing clamping device includes a testing platform, a Y-axis moving component, an X-axis moving component, an angle adjustment stage, and a part fixing mechanism. A Y-axis slide groove is provided in the middle of the testing platform. A roughness tester is fixedly mounted on one side of the Y-axis slide groove. The Y-axis moving component is locked in the Y-axis slide groove, and its locking position within the groove is adjustable. An X-axis moving component is connected to the Y-axis moving component, and an angle adjustment stage is provided on the X-axis moving component. A part fixing mechanism is connected to the top surface of the angle adjustment stage, which clamps and fixes the part to be tested. The X-axis moving component drives the angle adjustment stage to move along the X-axis, and the angle adjustment stage drives the part fixing mechanism to swing back and forth around the X-axis, adjusting the alignment angle with the roughness tester.

[0005] Furthermore, the cross-sectional shape of the Y-axis slide is an inverted T-shape, narrower at the top and wider at the bottom. The Y-axis moving assembly includes a mounting plate, bolts, an adjusting gear plate, a base, and a manual adjusting wheel. The mounting plate has a mounting hole symmetrically located on both the front and rear sides, which is opposite to the Y-axis slide. Two clamping blocks are embedded in the Y-axis slide, and the clamping blocks have screw holes corresponding to the mounting holes. Two bolts pass through the front and rear mounting holes and are tightened to the screw holes on the clamping blocks, thus fixing and locking the mounting plate in the Y-axis slide. The adjusting gear plate is fixedly connected to the middle of the mounting plate, and the base is slidably connected to the adjusting gear plate. A manual adjusting wheel is located between the base and the adjusting gear plate. Rotating the manual adjusting wheel allows the base to move along the Y-axis on the adjusting gear plate.

[0006] Furthermore, the middle part of the adjusting toothed plate is provided with a V-shaped protrusion along the Y-axis. The top surface of the V-shaped protrusion is flat, and both sides of the V-shaped protrusion are inclined surfaces. The bottom of the base is embedded in the V-shaped protrusion, and the base can slide along the V-shaped protrusion. A rack is also provided in the middle of the top surface of the V-shaped protrusion. The rack is arranged along the Y-axis. A gear that meshes with the rack is provided inside the base. A manual adjusting wheel that extends inward is provided on the side of the base. The inner end of the manual adjusting wheel is fixedly connected to the gear. Rotating the manual adjusting wheel from the outside can drive the gear to move along the rack, thereby driving the base to move along the Y-axis.

[0007] Furthermore, the X-axis moving assembly includes a base plate, a sliding plate, and a rotating telescopic rod. The base plate is fixedly mounted on the base, and an X-axis slide rail is provided on the base plate. The sliding plate is connected to the X-axis slide rail, and a rotating telescopic rod is provided on the side of the sliding plate and the base plate. The rotating telescopic rod can drive the sliding plate to slide on the X-axis slide rail.

[0008] Furthermore, the angle adjustment platform includes a guide platform, an adjustment block, and a drive rod. The top surface of the guide platform is an inner arc guide surface arranged along the Y-axis, and the bottom surface of the adjustment block is an outer arc surface with the same curvature as the inner arc guide surface. The outer arc surface is slidably connected to the inner arc guide surface. Limiting blocks are provided on the front and rear end faces of the guide platform and the adjustment block. The limiting blocks restrict the relative movement between the guide platform and the adjustment block along the X-axis. A drive rod is provided on one side of the angle adjustment platform. The drive rod is fixedly connected to the side of the guide platform along the Y-axis. The front end of the drive rod is connected to the adjustment block. The drive rod drives the adjustment block to slide back and forth along the inner arc guide surface to adjust the pitch angle of the part fixing mechanism.

[0009] Furthermore, the other side of the angle adjustment platform is provided with an angle limiting component, which includes a fixing nut and a positioning plate. The bottom of the positioning plate is fixedly connected to the side of the guide platform by screws. An arc-shaped elongated hole is opened on the upper part of the positioning plate. The fixing nut passes through the arc-shaped elongated hole and is fixedly connected to the side of the adjustment block. The drive rod drives the adjustment block to slide along the inner arc guide surface. The arc-shaped elongated hole limits the swing angle of the adjustment block by restricting the back-and-forth swing angle of the fixing nut.

[0010] Furthermore, the part fixing mechanism includes a placement platform, an arched support frame, and a top rod. The placement platform is fixedly connected to the top surface of the adjusting block. A T-shaped boss is provided in the middle of the placement platform along the Y-axis. The two ends of the arched support frame are slidably connected to the two sides of the T-shaped boss. The T-shaped boss is provided with a positioning groove for accommodating the workpiece. The bottom of the arched support frame is provided with a screw hole. The top rod is screwed into the screw hole. A knob is provided at the top of the top rod. The bottom of the top rod is a conical clamping head. Rotation can drive the top rod to descend, so that the conical clamping head presses the workpiece in the positioning groove.

[0011] Furthermore, the positioning groove includes a V-shaped groove and a rectangular groove. The V-shaped groove is arranged along the Y-axis, and the rectangular groove and the V-shaped groove are arranged perpendicularly to each other. The rectangular groove has a rounded chamfer inside.

[0012] The beneficial effects of this utility model are as follows: 1) This device can stably clamp parts. The V-groove can accommodate conventional rod-shaped parts. For parts with irregular shapes, the combination of the V-groove and the rectangular groove can stably support and accommodate the parts. The top rod set at the top can press the parts from the top. The conical clamping head has a small force-bearing area and precise pressing position, which has a good clamping and holding effect; 2) The Y-axis moving component and the X-axis moving component can adjust the position of the parts from the Y-axis and X-axis respectively, while the angle adjustment table can adjust the rotation of the parts. Through the adjustment in three directions, the roughness of different positions of the parts can be detected at one time, which improves the detection efficiency and detection flexibility.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-5 The present invention discloses an adjustable roughness testing clamping device, comprising a testing platform 1, a Y-axis moving assembly 2, an X-axis moving assembly 3, an angle adjustment table 4, and a part fixing mechanism 5. The testing platform 1 has a Y-axis slide groove 11 in its middle, and a roughness tester (not shown) is fixedly mounted on one side of the Y-axis slide groove 11. The Y-axis moving assembly 2 is locked in the Y-axis slide groove 11, and its locking position within the groove is adjustable. The X-axis moving assembly 3 is connected to the Y-axis moving assembly 2, and the angle adjustment table 4 is mounted on the X-axis moving assembly 3. The top surface of the angle adjustment table 4 is connected to the part fixing mechanism 5, which clamps and fixes the part to be tested. The X-axis moving assembly 3 drives the angle adjustment table 4 to move along the X-axis, and the angle adjustment table 4 drives the part fixing mechanism 5 to swing back and forth around the X-axis, adjusting the alignment angle with the roughness tester.

[0021] The Y-axis slide 11 has an inverted T-shape with a narrower top and a wider bottom. The Y-axis moving assembly 2 includes a mounting plate 21, bolts 22, an adjusting gear plate 23, a base 24, and a manual adjusting wheel 25. The mounting plate 21 has a mounting hole 211 symmetrically arranged on its front and rear sides, which is opposite to the Y-axis slide 11. Two clamping blocks 26 are embedded in the Y-axis slide 11. The clamping blocks 26 have screw holes corresponding to the mounting holes 211. The two bolts 22 pass through the front and rear mounting holes 211 and are tightened to the screw holes on the clamping blocks 26, thus fixing and locking the mounting plate 21 in the Y-axis slide 11. The adjusting gear plate 23 is fixedly connected to the middle of the mounting plate 21, and the base 24 is slidably connected to the adjusting gear plate 23. A manual adjusting wheel 25 is provided between the base 24 and the adjusting gear plate 23. Rotating the manual adjusting wheel 25 can move the base 24 along the Y-axis on the adjusting gear plate 23.

[0022] By tightening the bolt 22 to the clamping block 26, the mounting plate 21 can be fixed at different positions on the Y-axis slide groove 11. This allows for a large range of adjustment in the Y-axis direction. Subsequently, the base 24 is moved by adjusting the toothed plate 23, which is a slow adjustment in the Y-axis direction. This facilitates contact between the detection surface and the detector, preventing damage from hard contact.

[0023] The adjusting toothed plate 23 has a V-shaped protrusion 231 along the Y-axis in the middle. The top surface of the V-shaped protrusion 231 is flat, and both sides of the V-shaped protrusion 231 are inclined. The bottom of the base 24 is embedded in the V-shaped protrusion 231 and can slide along the V-shaped protrusion 231. A rack 232 is also provided in the middle of the top surface of the V-shaped protrusion 231. The rack 232 is arranged along the Y-axis. A gear that meshes with the rack 232 is provided inside the base 24. A manual adjusting wheel 25 is provided on the side of the base 24 that extends inward. The inner end of the manual adjusting wheel 25 is fixedly connected to the gear. Rotating the manual adjusting wheel 25 externally can drive the gear to move along the rack 232, thereby driving the base 24 to move along the Y-axis. The base 24 is slidably connected to the V-shaped protrusion 231. The manual adjustment wheel 25, which extends into the base 24, meshes with the rack 232. Rotating the manual adjustment wheel 25 drives the base 24 to move forward or backward, which can achieve the purpose of slow adjustment. The V-shaped protrusion 231 also has a limiting effect on the base 24 in the vertical direction, preventing the base 24 and the V-shaped protrusion 231 from disengaging.

[0024] The X-axis moving assembly 3 includes a base plate 31, a sliding plate 32, and a rotating telescopic rod 33. The base plate 31 is fixedly installed on the base 24. An X-axis slide rail is provided on the base plate 31. The sliding plate 32 is connected to the X-axis slide rail. The rotating telescopic rod 33 is provided on the side of the sliding plate 32 and the base plate 31. The rotating telescopic rod 33 can drive the sliding plate 32 to slide on the X-axis slide rail.

[0025] The angle adjustment platform 4 includes a guide platform 41, an adjustment block 42, and a drive rod 43. The top surface of the guide platform 41 is an inner arc guide surface 411 arranged along the Y-axis. The bottom surface of the adjustment block 42 is an outer arc surface 421 with the same curvature as the inner arc guide surface 411. The outer arc surface 421 is slidably connected to the inner arc guide surface 411. The front and rear end faces of the guide platform 41 and the adjustment block 42 are provided with limiting blocks 44, which restrict the relative movement between the guide platform 41 and the adjustment block 42 along the X-axis. A drive rod 43 is provided on one side of the angle adjustment platform 4. The drive rod 43 is fixedly connected to the side of the guide platform 41 along the Y-axis. The front end of the drive rod 43 is connected to the adjustment block 42. The drive rod 43 drives the adjustment block 42 to slide back and forth along the inner arc guide surface 411 to adjust the pitch angle of the part fixing mechanism 5. An angle limiting component 45 is provided on the other side of the angle adjustment table 4. The angle limiting component 45 includes a fixing nut 451 and a positioning plate 452. The bottom of the positioning plate 452 is fixedly connected to the side of the guide table by screws. The upper part of the positioning plate 452 has an arc-shaped elongated hole 453. The fixing nut 451 passes through the arc-shaped elongated hole 453 and is fixedly connected to the side of the adjustment block 42. The drive rod 43 drives the adjustment block 42 to slide along the inner arc guide surface 411. The arc-shaped elongated hole 453 limits the swing angle of the adjustment block 42 by limiting the back-and-forth swing angle of the fixing nut 451.

[0026] The part fixing mechanism 5 includes a placement platform 51, an arched support frame 52, and a top rod 53. The placement platform 51 is fixedly connected to the top surface of the adjusting block 42. A T-shaped boss 511 is provided in the middle of the placement platform 51 along the Y-axis. The two ends of the arched support frame 52 are slidably connected to the two sides of the T-shaped boss 511. The T-shaped boss 511 is provided with a positioning groove 54 for accommodating the workpiece. The bottom of the arched support frame 52 is provided with a screw hole 521. The top rod 53 is screwed into the screw hole 521. The top of the top rod 53 is provided with a knob 531. The bottom of the top rod 53 is a conical clamping head 532. Rotation can drive the top rod 53 to descend, so that the conical clamping head 532 presses the workpiece in the positioning groove 54. The positioning groove 54 includes a V-shaped groove 541 and a rectangular groove 542. The V-shaped groove 541 is arranged along the Y-axis, and the rectangular groove 542 and the V-shaped groove 541 are arranged perpendicularly. The rectangular groove 542 is provided with a rounded chamfer. The V-groove 541 can accommodate conventional rod-shaped parts. For irregularly shaped parts, the combination of the V-groove 541 and the rectangular groove 542 can stably support and accommodate the parts. The top rod 53 set at the top can press the parts from the top. The conical pressing head 532 has a small force-bearing area and precise pressing position, and has a good pressing and clamping effect.

[0027] The operation process of this utility model is as follows: After sliding the mounting plate 21 to the detection position, the mounting plate 21 is fixed to the Y-axis slide groove 11 by bolts 22 and clamping blocks 26. Then, the workpiece to be tested is placed into the V-groove 541 or rectangular groove 542. The arched support frame 52 is slid along the T-shaped boss to a position opposite to the workpiece. The push rod 53 is turned downward by the knob 531, so that the conical clamping head 532 contacts and presses the workpiece. During the tightening process of the conical clamping head 532, the arched support frame 52 and the T-shaped boss 541 are also tightened simultaneously. 11. Locking securely clamps the workpiece. By rotating the manual adjustment wheel 25, the base 24 is adjusted slightly along the Y-axis. By rotating the telescopic rod 33, the part above the slide plate 32 is adjusted along the X-axis. The adjustment block 42 and the part fixing mechanism 5 are driven by the drive rod 43 to slide along the inner arc guide surface 411 to adjust the pitch angle of the workpiece. The adjustment range of the angle does not exceed the central angle angle corresponding to the arc-shaped elongated hole 453. After the Y-axis, X-axis and pitch angle are all adjusted to the correct positions, the roughness tester inspects the workpiece.
