Description

Technical Field

[0001] This invention relates to the field of bearing testing technology, specifically to a batch testing device for the roundness of high-precision bearing rings. Background Technology

[0002] Bearings are components that fix and reduce the coefficient of friction of loads during mechanical transmission. When other machine parts move relative to each other on the shaft, they are used to reduce the coefficient of friction during power transmission and keep the center position of the shaft fixed. During the bearing production process, it is necessary to check the flatness of the outer circle of the product to verify whether the product meets the requirements.

[0003] For example, the bearing roundness detection device disclosed in CN209605792U can clamp bearings of different sizes and perform external roundness detection, but its actual operation has significant limitations. First, it can only clamp and perform external roundness detection on a single set of bearing rings. Second, it is difficult to pre-exclude bearing rings with severe surface dents and dimensional abnormalities in the same batch. The mixing of these bearing rings will greatly reduce the detection efficiency and data analysis effect of bearing rings.

[0004] To address this technical deficiency, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to enable the individual screening of abnormal bearing rings within the same batch while simultaneously clamping multiple sets of bearing rings, thereby reducing the inspection time for subsequent bearing rings. Furthermore, it allows for the simultaneous roundness inspection and orderly unloading of the inner and outer walls of the bearing rings within the same batch, significantly improving the roundness inspection efficiency of the bearing outer rings.

[0006] The objective of this invention can be achieved through the following technical solution: a batch inspection device for the roundness of high-precision bearing rings, comprising an inspection frame, wherein the front and rear ends of the inspection frame are provided with feeding ports at the upper middle part, and the two sides of the inspection frame are provided with unloading ports at the lower middle part, wherein the front and rear ends of the inspection frame are provided with limiting grooves at the lower end of the feeding ports, and the inner wall of the top of the limiting grooves is provided with a double-arch curved surface structure, wherein an inspection piece is provided at the center of the inner wall of the top of the inspection frame, and a batch clamping mechanism is provided at the center of the inspection frame corresponding to the inspection piece above and below;

[0007] The detection component includes a cylinder, which is located at the center of the inner wall of the top of the detection frame. A long plate is fixedly connected to the bottom of the cylinder via a push rod. Several sets of cross-hinged hinge rods are arranged at equal intervals at the bottom of the long plate. Sensor 1 and Sensor 2 are respectively mounted on the bottom ends of two adjacent sets of hinge rods via hinged mounting blocks. A probe head is respectively provided at the bottom of Sensor 1 and Sensor 2.

[0008] Furthermore, the batch clamping mechanism includes a receiving frame, which is movably installed at the center inside the detection frame, and rotating rods are fixedly installed at the top of both sides of the receiving frame. The two sets of rotating rods extend to the front and rear limit grooves respectively, and the front and rear ends of the rotating rods are semi-embedded and snapped into the inner wall of the bottom of the limit groove. The front ends of the two sets of rotating rods extend to the outside of the limit groove and are fixedly installed with toothed rings. A flipping component is provided between the two sets of toothed rings.

[0009] Furthermore, the top of the receiving frame is rotatably connected to a toothed disc at equal intervals, and a clamping cylinder is fixedly installed on the toothed disc. Several sets of inclined L-shaped clamping rods are hinged at equal intervals at the center of the frame of the clamping cylinder. A double-axis pressure plate is installed through the center of the inside of the clamping cylinder, and the double-axis pressure plate passes through the inside of the clamping cylinder and the toothed disc and extends into the inside of the receiving frame. The raised ends of the bottom rods of the several sets of L-shaped clamping rods press against the top plate of the double-axis pressure plate.

[0010] Furthermore, a second cylinder is provided at the center of the bottom inner wall of the receiving frame, and a mounting plate is fixedly connected to the top of the second cylinder via a push rod. Several sets of sleeves are sleeved on the top surface of the mounting plate, and the bottom of the dual-axis pressure plate passes through the corresponding sleeve.

[0011] Furthermore, the top surface of the receiving frame is rotatably connected to limit gears between two adjacent sets of gear discs, and the bottom shaft of one set of limit gears extends into the receiving frame and is equipped with a motor.

[0012] Furthermore, the material turning assembly includes an I-shaped push frame, which is movably disposed on the front end face of the detection frame and located between two sets of toothed rings. The two ends of the bottom edge of the I-shaped push frame are respectively connected to the double-shaft transmission wheel sleeve at the front end of the detection frame by rotation. The bottom surface and the top inner wall of the I-shaped push frame are provided with toothed groove groups.

[0013] Furthermore, the inner wall of the top of the I-shaped push frame is at the same height as the top surface of the toothed ring, a transmission gear is meshed at the center of the bottom of the I-shaped push frame, and a motor is provided between the center of the rear end of the transmission gear and the front end of the detection frame.

[0014] Furthermore, the bottom inner wall of the detection frame is provided with a base plate on both sides of the receiving frame, and the top surface of the base plate is fixedly installed with insert rods at equal intervals. The four sets of insert rods are sleeved with a top plate on the outside and at the top. A spring damping ring is wound around the outside of each set of insert rods between the top plate and the base plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention combines a detection component with a batch clamping mechanism. The batch clamping mechanism simultaneously clamps several sets of bearing rings and enables the bearing rings to rotate. The detection component then sinks to the corresponding bearing ring and performs roundness detection on the inner and outer rings. Data analysis is then performed to obtain the roundness data of the bearing rings. This structure enables batch clamping of multiple sets of bearing rings and also enables the rotation of multiple sets of bearing rings, thus effectively improving the inspection efficiency of bearing rings.

[0017] 2. The present invention also includes a material-turning assembly and a rod structure, which work in conjunction with a batch clamping mechanism. The material-turning mechanism drives the receiving frame to rotate clockwise and counterclockwise to screen and unload the bearing rings. Therefore, this structure can not only screen out abnormal bearing rings from the same batch of clamped bearing rings to reduce the inspection time of bearing rings, but also collect the inspected bearing rings separately to avoid bearing confusion, further improving the inspection efficiency of bearing rings.

[0028] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1 - Figure 8 As shown, a batch inspection device for the roundness of high-precision bearing rings includes an inspection frame 1. The front and rear ends of the inspection frame 1 are provided with feeding ports at the middle and upper ends, and the two sides of the inspection frame 1 are provided with unloading ports at the middle and lower ends. The front and rear ends of the inspection frame 1 are provided with limiting grooves 101 at the lower ends of the feeding ports, and the top inner wall of the limiting grooves 101 is provided with a double arch curved surface structure. An inspection piece 2 is provided at the center of the top inner wall of the inspection frame 1.

[0030] A batch clamping mechanism 3 is set at the center of the inner side of the detection frame 1 and at the corresponding positions above and below the detection piece 2. First, several sets of bearing rings are clamped in batches using the batch clamping mechanism 3. Then, the roundness of the inner and outer walls of the bearing rings in the same batch is detected using the detection piece 2, and the data of the bearing rings is analyzed.

[0031] Furthermore, the batch clamping mechanism 3 includes a receiving frame 31, which is movably installed at the center inside the detection frame 1. Rotating rods 32 are fixedly installed at the top of both sides of the receiving frame 31. The two sets of rotating rods 32 extend to the front and rear sets of limiting grooves 101 respectively. The front and rear ends of the rotating rods 32 are semi-embedded and snapped into the bottom inner wall of the limiting groove 101. The front ends of the two sets of rotating rods 32 extend to the outside of the limiting groove 101 and are fixedly installed with toothed rings 33.

[0032] The top of the receiving frame 31 is rotatably connected to a toothed disc 34 at equal intervals, and a clamping sleeve 35 is fixedly installed on the toothed disc 34. Several sets of inclined L-shaped clamping rods 36 are hinged at equal intervals at the center of the frame of the clamping sleeve 35. A double-axis pressure plate 37 is installed through the center of the inside of the clamping sleeve 35, and the double-axis pressure plate 37 passes through the inside of the clamping sleeve 35 and the toothed disc 34 and extends into the inside of the receiving frame 31. The raised ends of the bottom rods of the several sets of L-shaped clamping rods 36 press against the top plate of the double-axis pressure plate 37. A second cylinder 38 is installed at the center of the bottom inner wall of the receiving frame 31, and a mounting plate 39 is fixedly connected to the top of the second cylinder 38 through a push rod. Several sets of sleeves 310 are sleeved on the top surface of the mounting plate 39, and the bottom of the double-axis pressure plate 37 passes through the corresponding sleeve 310.

[0033] The process of the batch clamping mechanism 3 includes: firstly, inserting several sets of bearing rings into the corresponding chucks 35, with the top half of the bearing ring extending to the outside of the chucks 35. At this time, the cylinder 38 is activated, which uses the mounting plate 39 to pull several sets of sleeves 310 downwards, and the sleeves 310 pull the double-shaft pressure plate 37 downwards. The top plate of the double-shaft pressure plate 37 presses against the lifting rods at the bottom of the L-shaped clamping rods 36, thereby causing multiple sets of L-shaped clamping rods 36 to flip into a vertical position, so that the inner walls of the top of multiple sets of L-shaped clamping rods 36 can be used to press and clamp the outer wall of the bearing rings, thereby achieving simultaneous clamping of multiple sets of bearing rings. Then, the detection piece 2 is used for detection.

[0034] The detection component 2 includes a cylinder 201, which is located at the center of the inner top wall of the detection frame 1. The bottom of the cylinder 201 is fixedly connected to a long plate 202 via a push rod. The bottom of the long plate 202 is provided with several sets of cross-hinged hinge rods 203 at equal intervals. The bottom ends of two adjacent sets of hinge rods 203 are respectively provided with a sensor 1 and a sensor 2 via hinged mounting blocks. The bottom of the sensor 1 and the sensor 2 are respectively provided with a probe.

[0035] The detection process of test piece 2 includes: starting cylinder 201, using push rod to push long plate 202 and several sets of hinge rods 203 to sink until the probe of each set of intersecting hinge rods 203 sinks to the inner and outer walls of the corresponding bearing rings, using the probe to detect the roundness of the inner and outer walls of the bearing, and then transmitting the data to the display for data comparison through the sensor.

[0036] Meanwhile, the top surface of the receiving frame 31 is rotatably connected to the limiting gears 311 between the two adjacent sets of gear discs 34. The bottom shaft of one set of limiting gears 311 extends into the receiving frame 31 and is equipped with a motor 312. After multiple sets of bearing rings are clamped in batches, the motor 312 is started, which drives one set of limiting gears 311 to rotate. This set of rotating limiting gears 311 rotates with the adjacent gear discs 34.

[0037] Under the action of meshing transmission, multiple sets of toothed discs 34 and limit gears 311 are forced to rotate, and the bearing rings clamped inside the multiple sets of toothed discs 34 also rotate and rotate relative to the corresponding probe head, thereby performing roundness detection of the inner and outer walls of the circumferentially rotating bearing rings, thus achieving the effect of batch detection of bearing rings.

[0038] In addition to enabling batch clamping of multiple sets of bearing rings, it can also enable the rotation of multiple sets of bearing rings to perform roundness testing of the inner and outer walls of multiple sets of bearing rings, effectively improving the testing efficiency of bearing rings.

[0039] Example 2: Please refer to Figure 1 , Figure 5 and Figure 8 As shown, a material-turning assembly 4 is provided between the two sets of toothed rings 33. The material-turning assembly 4 includes an I-shaped push frame 41, which is movably disposed on the front end face of the detection frame 1 and located between the two sets of toothed rings 33. The two ends of the bottom frame of the I-shaped push frame 41 are respectively connected to the double-shaft transmission wheel 42 at the front end of the detection frame 1 by rotation. The bottom surface and the top inner wall of the I-shaped push frame 41 are provided with tooth grooves. The top inner wall of the I-shaped push frame 41 is at the same height as the top surface of the toothed rings 33. A transmission gear 43 is meshed at the bottom center of the I-shaped push frame 41, and a motor 44 is provided between the rear center of the transmission gear 43 and the front end face of the detection frame 1.

[0040] Please see Figure 1 and Figure 3 As shown, the bottom inner wall of the detection frame 1 is provided with a base plate 5 on both sides of the receiving frame 31, and the top surface of the base plate 5 is fixedly installed with a rod 501 at equal intervals. The four sets of rods 501 are sleeved on the top plate 502. The top plate 502 is wrapped around the outside of each set of rods 501 between the top plate 502 and the base plate 5.

[0041] It is worth noting that after multiple sets of bearing rings are clamped in batches, the bearing rings of the same batch are clamped in sequence. Under the same clamping force, some bearing rings that are not clamped have abnormalities such as dents on their outer walls or are smaller than the bearings of the same batch. Therefore, screening out abnormal bearings before testing the bearings of the same batch can improve the bearing testing efficiency.

[0042] Therefore, before inspecting the bearing rings in the same batch, the second motor 44 is started first. It drives the transmission gear 43 to rotate counterclockwise and meshes with the bottom tooth groove group of the I-shaped push frame 41, causing the I-shaped push frame 41 to move closer to the toothed ring 33 on one side. At the same time, the tooth groove group on the top inner wall of the I-shaped push frame 41 meshes with the nearby toothed ring 33, thereby realizing the counterclockwise rotation of this set of toothed rings 33 and the rotating rod 32.

[0043] Thus, the rotating rod 32 serves as the fulcrum, causing the receiving frame 31 to rotate counterclockwise by 180 degrees until several sets of bearing rings on the top surface of the receiving frame 31 correspond to several sets of insert rods 501 in the vertical row on one side of the detection frame 1. At this time, the abnormal bearing rings that are not clamped fall straight down and are fitted onto the outside of the corresponding insert rods 501. As the abnormal bearing rings fall, they press against the top plate 502 and the spring damping ring 503 to compress, thereby receiving and collecting bearing rings of abnormal size.

[0044] After the abnormal bearing rings are screened out, the motor 2 44 drives the transmission gear 43 to rotate clockwise, causing the I-shaped push frame 41 to move in the opposite direction and mesh with the gear ring 33 in the opposite direction. This forces the gear ring 33 and the rotating rod 32 to rotate clockwise. The rotating rod 32 then drives the receiving frame 31 to rotate 180 degrees clockwise, forcing the receiving frame 31 to rotate and reset, so as to perform the inner and outer wall inspection of the bearing rings.

[0045] It is also worth noting that after the roundness of the inner and outer walls of the same batch of bearing rings is tested, the above-mentioned flipping placement can be used to achieve the orderly unloading of the tested bearing rings. The unloading process specifically includes: in the reset state of the receiving frame 31, the motor 2 44 drives the transmission gear 43 to rotate clockwise, causing the I-shaped push frame 41 to move in the opposite direction and mesh with the corresponding toothed ring 33, forcing this set of toothed rings 33 and the rotating rod 32 to rotate clockwise, and using the rotating rod 32 as the fulcrum, driving the receiving frame 31 to rotate clockwise by 180 degrees until several sets of bearing rings on the top surface of the receiving frame 31 correspond to several sets of insert rods 501 in the vertical row on the other side of the testing frame 1.

[0046] At this time, the bearing rings being tested correspond vertically to the insert rod 501. After the batch clamping mechanism 3 is released, several sets of bearing rings being tested fall straight down and fit onto the outside of the corresponding insert rod 501. This facilitates the batch and individual unloading of the tested bearing rings, preventing confusion between the tested sets of bearing rings and making it easier to individually remove bearing rings with roundness defects, thereby improving the testing efficiency of bearing rings.

[0047] In use, the present invention first inserts several sets of bearing rings into the corresponding clamping sleeves 35, with the top half of the bearing ring extending to the outside of the clamping sleeve 35. At this time, the cylinder 38 is activated, which uses the mounting plate 39 to pull several sets of sleeves 310 downward, and the sleeves 310 pull the double-axis pressure plate 37 downward. The top plate of the double-axis pressure plate 37 presses against the lifting rod at the bottom of the L-shaped clamping rod 36, thereby causing multiple sets of L-shaped clamping rods 36 to flip into a vertical position, so that the inner walls of the top of multiple sets of L-shaped clamping rods 36 can be used together to press and clamp the outer wall of the bearing ring, thereby achieving simultaneous clamping of multiple sets of bearing rings.

[0048] Next, the motor 44 is started to drive the transmission gear 43 to rotate counterclockwise and mesh with the bottom tooth groove group of the I-shaped push frame 41, causing the I-shaped push frame 41 to move closer to the toothed ring 33 on one side. At the same time, the tooth groove group on the inner wall of the top of the I-shaped push frame 41 meshes with the approaching toothed ring 33, thereby realizing the counterclockwise rotation of this set of toothed rings 33 and the rotating rod 32. Thus, with the rotating rod 32 as the fulcrum, the receiving frame 31 is rotated counterclockwise by 180 degrees until several sets of bearing rings on the top surface of the receiving frame 31 correspond to several sets of insert rods 501 in the vertical row on one side of the detection frame 1. At this time, the abnormal bearing rings that are not clamped fall straight down and are sleeved on the outside of the corresponding insert rods 501. As the abnormal bearing rings fall, they press against the top plate 502 and the spring damping ring 503 to compress, thereby receiving and collecting the abnormally sized bearing rings.

[0049] Then, after the abnormal bearing rings are screened out, the motor 2 44 drives the transmission gear 43 to rotate clockwise, causing the I-shaped push frame 41 to move in the opposite direction and mesh with the gear ring 33 in the opposite direction, forcing this set of gear rings 33 and rotating rod 32 to rotate clockwise. Again, with the rotating rod 32 as the fulcrum, the receiving frame 31 is rotated 180 degrees clockwise, thereby forcing the receiving frame 31 to rotate and reset, so as to perform the inner and outer wall inspection of the bearing rings.

[0050] Furthermore, cylinder 201 is activated, and the push rod pushes the long plate 202 and several sets of hinge rods 203 to sink until the probes of each set of intersecting hinge rods 203 sink to the inner and outer walls of the corresponding bearing rings. At the same time, motor 312 is activated, which drives one set of limiting gears 311 to rotate. The rotating limiting gears 311 and the adjacent gear disks 34 rotate. Under the action of meshing transmission, multiple sets of gear disks 34 and limiting gears 311 are forced to rotate. The bearing rings clamped inside the multiple sets of gear disks 34 also rotate and rotate relative to the corresponding probes, thereby detecting the roundness of the inner and outer walls of the circumferentially rotating bearing rings.

[0051] Finally, the receiving frame 31 is reset, and the second motor 44 drives the transmission gear 43 to rotate clockwise, causing the I-shaped push frame 41 to move in the opposite direction and mesh with the corresponding gear ring 33. This forces the gear ring 33 and the rotating rod 32 to rotate clockwise. With the rotating rod 32 as the fulcrum, the receiving frame 31 is rotated 180 degrees clockwise until several sets of bearing rings on the top surface of the receiving frame 31 correspond to several sets of insert rods 501 in the vertical row on the other side of the detection frame 1. At this time, the detected bearing rings correspond vertically to the insert rods 501. After the batch clamping mechanism 3 is released, several sets of detected bearing rings fall straight down and fit onto the outside of the corresponding insert rods 501, which facilitates the batch individual unloading of the detected bearing rings.
