Description

Technical Field

[0001] The invention relates to the technical field of bearing detection, in particular to a profile detector for one-way testing of bearing chamfers. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The bearing sleeve of the bearing has a chamfer. The chamfer requirements of bearing products are very strict, with very good consistency and good appearance quality. In order to eliminate the problems in bearing application and appearance quality caused by the chamfer size, it is necessary to carefully check the chamfer size and angle of the bearing sleeve. The chamfer of the bearing sleeve is detected by a profilometer.

[0003] The profiler is a two-coordinate measuring instrument. The instrument sensor slides at a constant speed relative to the surface of the workpiece being measured. The sensor's stylus senses the geometric changes of the surface being measured and converts them into electrical signals. The electrical signals are amplified and processed, and then converted into digital signals and stored in the memory of the computer system. The computer digitally filters the original surface contour, separates the surface roughness component, and then calculates. The measurement result is the actual value of a certain curve calculated and its coordinates from the reference point, or the enlarged actual contour curve. The measurement result is output through the display. It can measure the groove depth, groove width and various chamfer angles, width, depth, radius of fillet, position and other parameters of various groove parts. As a precision measuring instrument, it is widely used in automobile manufacturing, railway industry and bearing manufacturing.

[0004] When the profiler detects the chamfer of the bearing sleeve, it is necessary to clamp and fix the bearing sleeve through the clamping parts on the profiler to facilitate the profiler to detect the chamfer of the bearing sleeve. However, most of the clamping parts on the current profiler require manual placement of the bearing sleeve on the clamping parts for clamping. After the inspection, the bearing sleeve is removed from the clamping parts, and then the next bearing sleeve to be inspected is placed on the clamping parts for clamping. Manual placement of the bearing sleeve on the clamping parts wastes manpower and is inconvenient to use. Therefore, the applicant has developed a new technical solution in the actual production process to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0031] 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.

[0032] A profile detector for one-way testing of bearing chamfers, such as Figure 1 , including a testing platform 1, on which a storage mechanism 2 and a collecting mechanism 3 are provided. The storage mechanism 2 is used to store the bearing sleeve 4 to be tested. A swing plate 5 is hinged on the testing platform 1 through a hinge, and the swing plate 5 is provided with a clamping member for clamping the bearing sleeve 4 on the storage mechanism 2 and transferring the clamped bearing sleeve 4 to the collecting mechanism 3. When the clamping member clamps the bearing sleeve 4 and the swing plate 5 is vertical, a profiler 6 for chamfering the bearing sleeve 4 clamped by the clamping member is provided at the top of the testing platform 1. The storage mechanism 2 is opposite to the swing plate 5, and the collecting mechanism 3 is located on one side of the storage mechanism 2.

[0033] like Figure 1When in use, the swing plate 5 is driven by the hinge to rotate in the direction close to the storage mechanism 2 until the swing plate 5 is rotated to a horizontal state, and then the first bearing sleeve 4 on the storage mechanism 2 is clamped by the clamping piece on the swing plate 5. At this time, the bearing sleeve 4 is horizontal, and the swing plate 5 is driven by the hinge to rotate in the direction away from the storage mechanism 2 until the swing plate 5 is rotated to a vertical state. At this time, the bearing sleeve 4 is vertical, and then the bearing sleeve 4 clamped by the clamping piece is chamfered and detected by the profilometer 6. After the detection is completed, the swing plate 5 is driven by the hinge to rotate in the direction close to the storage mechanism 2 until the swing plate 5 is rotated to a horizontal state, and then the first bearing sleeve 4 after the detection is placed on the collecting mechanism 3 by the clamping piece on the swing plate 5, and the second bearing sleeve 4 on the storage mechanism 2 is clamped by the clamping piece, and so on, the automatic removal and placement of the bearing sleeve 4 on the clamping piece can be realized, thereby saving manpower.

[0034] The profiler 6 is an existing structure, and this application will not describe it in detail here.

[0035] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The storage mechanism 2 includes a storage barrel 7 and a bottom plate 8 vertically slidably connected to the storage barrel 7. A mounting groove 9 is provided at the top of the detection table 1. The bearing sleeve 4 is placed at the top of the bottom plate 8. The opening of the storage barrel 7 faces upward, and the top of the storage barrel 7 passes through the mounting groove 9. At this time, the outer wall of the storage barrel 7 is fixedly connected to the groove wall of the mounting groove 9. The bottom end of the storage barrel 7 is provided with a first electric cylinder 10 for pushing the bottom plate 8 to move vertically. A central column 12 is vertically provided at the bottom end of the storage barrel 7. A central groove 13 is provided at the center of the bottom plate 8. The top of the central column 12 passes vertically through the central groove 13 and is flush with the top of the storage barrel 7. Multiple bearing sleeves 4 placed on the top of the bottom plate 8 are arranged from bottom to top, and the top of the central column 12 passes through the bearing sleeve 4. The storage barrel 7 is provided with a limiting member for limiting the bearing sleeve 4 arranged from bottom to top on the bottom plate 8. The structure of the collecting mechanism 3 is consistent with that of the storage mechanism 2.

[0036] like Figure 1 and Figure 2 and Figure 3 and Figure 4 After the swing plate 5 rotates to a horizontal state in the direction close to the storage mechanism 2, the first electric cylinder 10 is opened, and the piston rod of the first electric cylinder 10 pushes the bottom plate 8 to move vertically upward. At this time, the bottom plate 8 pushes the bearing sleeve 4 to move upward until the first bearing sleeve 4 is exposed from the barrel mouth of the storage barrel 7 and enters the clamping piece on the swing plate 5. At this time, the bearing sleeve 4 is horizontal, and then the first bearing sleeve 4 is clamped by the clamping piece, and the piston rod of the first electric cylinder 10 pushes the bottom plate 8 to move vertically downward, so that the bearing sleeves 4 on the bottom plate 8 are all located in the storage barrel 7;

[0037] When the first bearing sleeve 4 is inspected and the swing plate 5 is rotated to a horizontal state in a direction close to the storage mechanism 2, the first bearing sleeve 4 after inspection is placed on the bottom plate 8 in the collection mechanism 3 by the clamping piece on the swing plate 5, and then the bottom plate 8 is moved vertically downward by the first electric cylinder 10 in the collection mechanism 3 until the first bearing sleeve 4 enters the storage barrel 7 in the collection mechanism 3, and then the second bearing sleeve 4 is exposed from the barrel mouth of the storage barrel 7 and enters the clamping piece on the swing plate 5 by the cooperation of the first electric cylinder 10 in the storage mechanism 2 and the bottom plate 8, and then the second bearing sleeve 4 is clamped by the clamping piece, and so on, the bearing sleeve 4 on the clamping piece can be automatically taken and placed, saving manpower;

[0038] By limiting the bearing sleeves 4 on the bottom plate 8 through the limiting member, it is possible to reduce the possibility of the bearing sleeves 4 arranged from bottom to top tipping over, which would cause the bearing sleeves 4 to be unable to horizontally protrude from the barrel opening of the storage barrel 7 .

[0039] like Figure 3 The limiting member includes a slide groove 14 horizontally arranged at the bottom end of the storage barrel 7, and two sliders 15 are horizontally slidably connected in the slide groove 14, and the tops of the two sliders 15 are vertically provided with limiting rods 16, and the top of the bottom plate 8 is provided with a transition groove 17 corresponding to the slide groove 14, and the transition groove 17 is connected to the central groove 13, and the tops of the two limiting rods 16 pass through the transition groove 17 and are flush with the top of the storage barrel 7, and the end of the central column 12 close to the two limiting rods 16 is rotatably connected with a threaded barrel 18, and the two threaded barrels 18 are threadedly connected with screws 19, and the ends of the two screws 19 away from the central column 12 extend to the outside of the threaded barrel 18 and are fixedly connected to the limiting rod 16, and the sides of the two limiting rods 16 facing away from each other are in contact with the inner wall of the bearing sleeve 4.

[0040] like Figure 3 When the bottom plate 8 moves vertically, the limiting rods 16 and the center column 12 will not move with the bottom plate 8. At this time, the two limiting rods 16 in contact with the inner wall of the bearing sleeve 4 can limit the bearing sleeve 4, thereby reducing the possibility of the bearing sleeve 4 being tilted from bottom to top, which causes the bearing sleeve 4 to be unable to horizontally expose the barrel opening of the storage barrel 7.

[0041] By rotating the two threaded barrels 18, since the threaded barrels 18 are threadedly connected to the screw rod 19, and the screw rod 19 is fixedly connected to the limit rod 16, the distance between the limit rod 16 and the center column 12 can be adjusted by rotating the threaded barrels 18 to adapt to bearing sleeves 4 of various diameters.

[0042] like Figure 1The hinged part includes two baffles 20 relatively arranged at the top of the detection platform 1, and the swing plate 5 is rotatably connected between the two baffles 20. A first servo motor 21 for driving the swing plate 5 to rotate is provided on one of the baffles 20. The purpose of this setting is that when it is necessary to drive the swing plate 5 to rotate, it is only necessary to turn on the first servo motor 21. At this time, the rotating shaft of the first servo motor 21 will rotate the swing plate 5 between the two baffles 20, which is simple and convenient to use.

[0043] like Figure 1 and Figure 5 The clamping member includes a connecting groove 22 provided on the side of the swing plate 5 close to the baffle 20, and the connecting groove 22 is connected to the top of the swing plate 5, and a rotating plate 23 is rotatably connected between the groove walls on the opposite sides of the connecting groove 22, and a second servo motor 24 for driving the rotating plate 23 to rotate is provided on the swing plate 5, and the top of the rotating plate 23 is located outside the connecting groove 22, and a circular pick-up and place groove 25 is provided on one side of the rotating plate 23, and second electric cylinders 26 are provided on the opposite sides of the rotating plate 23, and the piston rod of the second electric cylinder 26 One end of each of them passes through the rotating plate 23 and is provided with a clamping plate 27 located in the pick-and-place groove 25 for clamping the bearing sleeve 4. A clamping groove 28 that penetrates the swing plate 5 and is connected to the connecting groove 22 is opened on one side of the swing plate 5. When the two clamping plates 27 clamp the bearing sleeve 4, the rotating plate 23 is driven to rotate by the second servo motor 24 until the pick-and-place groove 25 on the rotating plate 23 is aligned with the clamping groove 28. A fixing part is provided on the swing plate 5 for fixing and clamping the bearing sleeve 4 in the pick-and-place groove 25.

[0044] like Figure 1 and Figure 5 , when the swing plate 5 rotates to a horizontal state in a direction close to the storage mechanism 2, the pick-and-place groove 25 on the rotating plate 23 corresponds to the storage barrel 7 in the storage mechanism 2. At this time, the piston rod of the first electric cylinder 10 in the storage mechanism 2 pushes the bottom plate 8 to move vertically upward until the first bearing sleeve 4 is exposed from the barrel mouth of the storage barrel 7 and enters the pick-and-place groove 25 on the rotating plate 23. At this time, the first bearing sleeve 4 is located between the two clamping plates 27, and then the piston rods of the two second electric cylinders 26 push the two clamping plates 27 closer to each other until the two clamping plates 27 clamp the first bearing sleeve 4. The bottom plate 8 is pushed to move vertically downward by the piston rod of the first electric cylinder 10, so that the bearing sleeves 4 on the bottom plate 8 are all located in the storage barrel 7, and then the swing plate 5 is rotated in a direction away from the storage mechanism 2 through the hinge until the swing plate 5 rotates to a vertical state, and then the rotating plate 23 is driven to rotate 180 degrees by the rotating shaft of the second servo motor 24. At this time, the pick-and-place groove 25 on the rotating plate 23 will be aligned with the clamping groove 28 on the swing plate 5 (such as Figure 8 ), and then the bearing sleeve 4 in the pick-and-place groove 25 is fixedly clamped by the fixing piece on the swing plate 5, and then the chamfering of the bearing sleeve 4 clamped by the clamping piece is detected by the profilometer 6, and after the detection is completed;

[0045] The fixing member is released from the fixing clamping of the bearing sleeve 4, and the rotating plate 23 is driven by the rotating shaft of the second servo motor 24 to rotate 180 degrees again, so that the pick-up and put-down groove 25 is located above the swing plate 5 (such as Figure 5 ), and then the swing plate 5 is driven to rotate in the direction close to the storage mechanism 2 through the hinge until the swing plate 5 is rotated to a horizontal state, and then the rotating shaft of the second servo motor 24 drives the rotating plate 23 to rotate in the direction close to the collecting mechanism 3 until the pick-up and placement groove 25 on the rotating plate 23 is aligned with the storage barrel 7 in the collecting mechanism 3, and then the two clamping plates 27 are released from the clamping of the first bearing sleeve 4, at this time, the first bearing sleeve 4 will fall onto the bottom plate 8 in the collecting mechanism 3, and then the rotating shaft of the second servo motor 24 drives the rotating plate 23 to rotate in the direction close to the storage mechanism 2 until the pick-up and placement groove 25 on the rotating plate 23 is aligned with the storage barrel 7 in the storage mechanism 2, and then through the cooperation of the first electric cylinder 10 in the storage mechanism 2 and the bottom plate 8, the second bearing sleeve 4 is exposed from the barrel mouth of the storage barrel 7 and enters the pick-up and placement groove 25 on the swing plate 5, and then the second bearing sleeve 4 is clamped by the two clamping plates 27, and so on, the automatic pick-up and placement of the bearing sleeve 4 can be achieved, thereby saving manpower;

[0046] The bearing sleeve 4 in the pick-and-place groove 25 is clamped by two clamping plates 27 and fixedly clamped by a fixing member, thereby improving the stability of the bearing sleeve 4 and reducing the displacement or rotation of the bearing sleeve 4 when the bearing sleeve 4 is detected.

[0047] like Figure 5 The fixing member includes two opposite moving plates 29, and the two moving plates 29 are respectively located on both sides of the swing plate 5. Two opposite slots 30 are provided on the side of the two moving plates 29 close to the swing plate 5. Two sliding columns 31 are horizontally arranged on the opposite sides of the swing plate 5, and the ends of the two sliding columns 31 away from the swing plate 5 respectively pass horizontally through the two slots 30 on the moving plates 29. Two vertical plates 32 are vertically arranged on the top of the two moving plates 29, and a clamping plate 33 is horizontally arranged above the side of the vertical plates 32 close to the swing plate 5. The swing plate 5 is provided with a pushing member for simultaneously driving the two moving plates 29 to move closer to or away from each other.

[0048] like Figure 8 When the pick-up and placement groove 25 on the rotating plate 23 is aligned with the clamping groove 28 on the swing plate 5, and the bearing sleeve 4 in the pick-up and placement groove 25 needs to be fixedly clamped, it is only necessary to drive the two movable plates 29 to approach each other at the same time through the pushing member. At this time, the vertical plate 32 and the clamping plate 33 will move with the movable plate 29 until the four clamping plates 33 are all pressed against the side wall of the bearing sleeve 4. At this time, the bearing sleeve 4 can be fixedly clamped by the four clamping plates 33. There is a gap between two adjacent clamping plates 33, which will not affect the detection of the chamfer of the bearing sleeve 4 by the profiler 6.

[0049] like Figure 8 The pushing member includes fixed plates 34 that are both arranged on the two movable plates 29, and the two fixed plates 34 are both located on one side of the swing plate 5. The two fixed plates 34 are opposite to each other, and the side of the swing plate 5 close to the fixed plate 34 is rotatably connected to a gear 35 located between the two fixed plates 34. The sides of the two fixed plates 34 close to each other are both provided with a rack 36 meshing with the gear 35. The swing plate 5 is provided with a third electric cylinder 37 for pushing one of the fixed plates 34 to move horizontally.

[0050] like Figure 8 When it is necessary to drive the two movable plates 29 closer to or farther from each other at the same time, it is only necessary to open the third electric cylinder 37. At this time, the piston rod of the third electric cylinder 37 will push one of the fixed plates 34 to move horizontally. At this time, because the racks 36 on the two fixed plates 34 are meshed with the gear 35, and the gear 35 is located between the two racks 36, when one of the fixed plates 34 moves horizontally, the other fixed plate 34 can be driven to move in the opposite direction at the same time through the cooperation of the gear 35 and the two racks 36. At this time, the two fixed plates 34 will respectively drive the two movable plates 29 closer to or farther from each other, which is simple and convenient to use.

[0051] like Figure 1 and Figure 6 When the pick-up and placement groove 25 is aligned with the clamping groove 28, a cleaning member for cleaning the inner wall of the bearing sleeve 4 in the pick-up and placement groove 25 is provided on the detection platform 1. The cleaning member includes a vertical plate 38 vertically arranged at the top of the detection platform 1, and a brush 39 is provided on the side of the vertical plate 38 close to the swing plate 5. The vertical plate 38 is horizontally slidably connected to the top of the detection platform 1 in the direction of approaching or moving away from the swing plate 5, and a horizontal plate 40 is horizontally provided on one side of the vertical plate 38, and a bolt 41 is threadedly connected to the horizontal plate 40, and one end of the bolt 41 passes through the horizontal plate 40 and contacts the top of the detection platform 1.

[0052] like Figure 7 and Figure 8 , when the pick-and-place groove 25 on the rotating plate 23 is aligned with the clamping groove 28 on the swing plate 5, and the fixing part on the swing plate 5 fixes and clamps the bearing sleeve 4 in the pick-and-place groove 25, the swing plate 5 is first driven by the hinge to rotate to a horizontal state in the direction close to the storage mechanism 2. At this time, the vertical plate 38 will enter the bearing sleeve 4 in the pick-and-place groove 25. At this time, the bristles 39 on one side of the vertical plate 38 can be used to clean the side of the inner wall of the bearing sleeve 4 that needs to be inspected, and then the swing plate 5 is driven by the hinge to rotate to a vertical state in the direction away from the storage mechanism 2, and the bearing sleeve 4 clamped by the clamping part can be chamfered and inspected by the profilometer 6, thereby reducing the impact of impurities on the inner wall of the bearing sleeve 4 on the accuracy of inspection. Figure 6By loosening the bolt 41, the vertical plate 38 is pushed to move toward or away from the swing plate 5. At this time, the position of the vertical plate 38 can be adjusted to adapt to bearing sleeves 4 of different diameters.

[0053] like Figure 1 A waste area 42 is provided on the testing table 1, and the waste area 42 corresponds to the collecting mechanism 3. The purpose of this setting is that the collecting mechanism 3 is used to collect the bearing sleeves 4 that have passed the test. When the tested bearing sleeves 4 are unqualified and the swing plate 5 rotates to a horizontal state in the direction close to the storage mechanism 2, the rotating plate 23 is driven by the rotating shaft of the second servo motor 24 to rotate in the direction close to the waste area 42 until the pick-up and placement groove 25 is aligned with the waste area 42, and then the clamping of the clamping plate 27 on the bearing sleeve 4 is released. At this time, the unqualified bearing sleeve 4 can be placed in the waste area 42, which is simple and convenient to use.

[0054] The working process is as follows:

[0055] In the first step, the first servo motor 21 is turned on, and the rotating shaft of the first servo motor 21 drives the swing plate 5 to rotate between the two baffles 20 toward the storage mechanism 2 to a horizontal state, at which time the access slot 25 on the rotating plate 23 corresponds to the storage barrel 7 in the storage mechanism 2;

[0056] In the second step, the piston rod of the first electric cylinder 10 in the storage mechanism 2 pushes the bottom plate 8 to move vertically upward until a bearing sleeve 4 is exposed from the barrel mouth of the storage barrel 7 and enters the pick-up and release groove 25 on the rotating plate 23. At this time, the bearing sleeve 4 is located between the two clamping plates 27. Then, the piston rods of the two second electric cylinders 26 push the two clamping plates 27 closer to each other until the two clamping plates 27 clamp the bearing sleeve 4. Then, the piston rod of the first electric cylinder 10 pushes the bottom plate 8 to move vertically downward, so that the bearing sleeves 4 on the bottom plate 8 are all located in the storage barrel 7.

[0057] In the third step, the swing plate 5 is rotated upward to a vertical position away from the storage mechanism 2 by the first servo motor 21, and then the rotating plate 23 is driven to rotate 180 degrees by the rotating shaft of the second servo motor 24, so that the pick-and-place groove 25 on the rotating plate 23 is aligned with the clamping groove 28 on the swing plate 5;

[0058] The fourth step is to push one of the fixed plates 34 to move horizontally by the piston rod of the third electric cylinder 37. At this time, because the racks 36 on the two fixed plates 34 are meshed with the gear 35, and the gear 35 is located between the two racks 36, when one of the fixed plates 34 moves horizontally, the other fixed plate 34 can be driven to move in the opposite direction at the same time through the cooperation of the gear 35 and the two racks 36. When the two fixed plates 34 approach each other, the two fixed plates 34 will respectively drive the two moving plates 29 to approach each other. At this time, the vertical plate 32 and the clamping plate 33 will move with the moving plate 29 until the four clamping plates 33 are pressed against the side wall of the bearing sleeve 4 to fix and clamp the bearing sleeve 4.

[0059] Step 5: The swing plate 5 is rotated downward to a horizontal state toward the storage mechanism 2 by the first servo motor 21. At this time, the vertical plate 38 enters the bearing sleeve 4 in the pick-and-place groove 25, and the bristles 39 on one side of the vertical plate 38 clean the inner wall of the bearing sleeve 4 that needs to be inspected;

[0060] Step 6: The swing plate 5 is rotated upward to a vertical position away from the storage mechanism 2 by the first servo motor 21, and then the bearing sleeve 4 clamped by the clamping member is chamfered by the profilometer 6;

[0061] Step 7: After the detection is completed, the four clamping plates 33 in the fourth step are released from fixing the bearing sleeve 4, and then the rotating plate 23 is driven to rotate 180 degrees by the rotating shaft of the second servo motor 24, so that the pick-and-place slot 25 is located above the swing plate 5, and then the swing plate 5 is rotated downward to a horizontal state in a direction close to the storage mechanism 2 by the first servo motor 21;

[0062] In the eighth step, the rotating plate 23 is driven by the rotating shaft of the second servo motor 24 to rotate in the direction close to the collecting mechanism 3 until the pick-up and placement groove 25 on the rotating plate 23 is aligned with the storage barrel 7 in the collecting mechanism 3, and then the clamping of the two clamping plates 27 on the bearing sleeve 4 is released, and the bearing sleeve 4 after inspection will fall onto the bottom plate 8 in the collecting mechanism 3, and then the bottom plate 8 is moved vertically downward by the first electric cylinder 10 in the collecting mechanism 3 until the bearing sleeve 4 after inspection enters the storage barrel 7 in the collecting mechanism 3;

[0063] In the ninth step, the rotating shaft of the second servo motor 24 drives the rotating plate 23 to rotate toward the storage mechanism 2 until the access groove 25 on the rotating plate 23 is aligned with the storage barrel 7 in the storage mechanism 2, and then repeat the second step, the third step, the fourth step, the fifth step, the sixth step, the seventh step, the eighth step, and the ninth step in sequence.

[0064] In the eighth step, when the detected bearing sleeve 4 is unqualified, the rotating plate 23 is driven by the rotating shaft of the second servo motor 24 to rotate toward the scrap area 42 until the pick-up and placement groove 25 on the rotating plate 23 is aligned with the scrap area 42, and then the two clamping plates 27 are released from clamping the bearing sleeve 4, and the unqualified bearing sleeve 4 can be placed in the scrap area 42.

[0065] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
