DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention are described clearly and completely below. 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.

[0031] Embodiment 1: A bearing seat performance testing device, combined with the attached Figure 1 To Attachment Figure 7 , including a workbench 1, a transmission slot is opened on the front side of the workbench 1, and an external transmission component and a pushing component are used to transport the bearing seat to be tested to the detection position. A support frame 2 is fixedly connected to the top of the workbench 1, and a card frame 3 is fixedly connected to the middle of the rear side of the top of the workbench 1. A display screen 4 is fixedly connected to the upper part of the card frame 3, and an inner diameter measuring instrument 5 is fixedly connected to the lower part of the card frame 3. The inner diameter measuring instrument 5 is used to detect the inner diameter value and change of the bearing seat. The display screen 4 is electrically connected to the inner diameter measuring instrument 5. The support frame 2 is connected to a rotating frame 6 along an arc sliding. The rotating frame 6 An electric push rod 7 is fixed on the top, and the rotating frame 6 is slidably connected to the pressing frame 8 in the up and down directions. When the electric push rod 7 is extended, it contacts the pressing frame 8. A first spring 9 symmetrically distributed along the pressing frame 8 is fixed between the rotating frame 6 and the pressing frame 8. The rotating frame 6 is slidably connected to a limit frame 10 symmetrically distributed along the front and back of the rotating frame 6. A second spring 11 is fixed between the limit frame 10 and the rotating frame 6. The left, middle and right sides of the support frame 2 are all provided with card slots 12. The three card slots 12 are distributed at equal intervals. The limit frame 10 is limited by the card slot 12. The support frame 2 is fixedly connected with a third spring 13 symmetrically distributed along the left and right sides of the support frame 2, and the third spring 13 contacts the rotating frame 6. The left and right sides of the support frame 2 are slidably connected with arc plates 14 symmetrically distributed along the front and back of the support frame 2. When the limit frame 10 slides in an arc shape with the rotating frame 6, the limit frame 10 contacts the arc plate 14, and the end faces of the two contacting are set as wedge-shaped surfaces. The arc plate 14 is used to support the limit frame 10 upward, and the arc plate 14 guides the limit frame 10. A fourth spring 15 is fixedly connected between adjacent arc plates 14. The support frame The left and right sides of the electric push rod 7 are slidably connected with L-shaped push rods 16 symmetrically distributed along the front and back of the support frame 2. The L-shaped push rods 16 are used to lift the limit frame 10 to the top of the arc plate 14. The top of the L-shaped push rod 16 contacts the limit frame 10. The lower part of the electric push rod 7 is fixedly connected with a fixing frame 17 symmetrically distributed along the front and back of the electric push rod 7. The fixing frame 17 is rotatably connected with a rotating plate 18 for lifting the adjacent L-shaped push rod 16. The fixing frame 17 limits the rotating plate 18 to rotate upward in one direction, and the rotating plate 18 moves to contact the adjacent L-shaped push rod 16.

[0032] Before using the present device to perform a performance test on a bearing seat, the bearing seat to be tested is first automatically transported to the bracket 3 through an external transmission component and a pushing component, the inner diameter measuring instrument 5 contacts the inner wall of the bearing seat, detects the initial inner diameter value of the bearing seat, and displays the test result on the display screen 4, then the electric push rod 7 is controlled to extend downward so that the electric push rod 7 contacts the pressure frame 8 and pushes the pressure frame 8 to move downward, the first spring 9 is compressed, and the pressure frame 8 applies a gradually increasing load to the bearing seat from directly above, during the pressure application process, the inner diameter measuring instrument 5 collects a large number of data points along the circumference of the inner wall of the bearing seat, and then analyzes and detects whether the inner diameter value of the bearing seat has changed, and displays the test result on the display screen 4.

[0033] Starting loading from directly above can ensure that the force is perpendicular to the pressure-bearing surface of the bearing seat, making the force distribution more uniform. Uniform loading helps to truly reflect the overall load-bearing performance and structural stability of the bearing seat, avoid introducing unnecessary lateral force or torque, thereby avoiding interference with the test results, and reduce local stress concentration caused by eccentric loading, thereby obtaining more accurate test results.

[0034] After the pressure is applied, the electric push rod 7 is controlled to disengage from the pressure frame 8, and the first spring 9 is reset to drive the pressure frame 8 to slide upward and reset. Then, the rotating frame 6 is pushed to slide to the left along the support frame 2 in an annular manner. The rotating frame 6 drives the electric push rod 7, the pressure frame 8, the first spring 9, the limit frame 10 and the second spring 11 to move along the support frame 2 in an annular manner. The limit frame 10 is first squeezed out of the middle slot 12, and the second spring 11 is compressed. When the limit frame 10 moves to the left slot 12, the second spring 11 is reset to drive the limit frame 10 to be stuck in the left slot 12, so that the pressure frame 8 is positioned to the fixed point to be measured on the left side of the bearing seat, and then a gradually increasing load is applied to the bearing seat from the left side in the same way as above. After completing the detection of this point, the rotating frame 6 is pushed to the right to slide along the support frame 2 in an annular manner, so that the pressure frame 8 is positioned to the fixed point to be measured on the right side of the bearing seat, and then a gradually increasing load is applied to the bearing seat from the right side in the same way as above.

[0035] If the bearing seat can still maintain its structural integrity after the above multi-point test, without excessive deformation or damage, and the inner diameter value test results are all within the qualified evaluation range, then it is a bearing seat with qualified performance, otherwise it is an unqualified bearing seat.

[0036] After completing the pressure test directly above, in the process of pushing the rotating frame 6 to slide in an annular direction to the left or right, taking the annular sliding to the right as an example, the rotating frame 6 compresses the third spring 13 on the right, and the rotating frame 6 drives the limiting frame 10 to contact with the top end of the L-shaped push rod 16 on the right. At this time, the limiting frame 10 is positioned in the right slot 12. In the process of controlling the electric push rod 7 to contact with the pressure frame 8, the electric push rod 7 drives the rotating plate 18 to move downward through the fixed frame 17. The rotating plate 18 rotates upward to pass over the L-shaped push rod 16 on the right, and reverses and resets under the action of gravity after passing. In the process of controlling the electric push rod 7 to reset, the electric push rod 7 drives the rotating plate 18 to move upward through the fixed frame 17. When the rotating plate 18 contacts the L-shaped push rod 16 on the right, it is limited by the fixed frame 17 and cannot rotate downward, thereby The L-shaped push rod 16 on the right cannot pass upward and can only push the L-shaped push rod 16 on the right to slide upward. The L-shaped push rod 16 on the right pushes the limit frame 10 upward, and the second spring 11 is compressed, so that the limit frame 10 disengages from the right-side slot 12. At the same time, the limit frame 10 squeezes the two arc plates 14 on the right side to move closer to the middle, and the fourth spring 15 on the right side is compressed, so that the limit frame 10 passes upward to above the arc plate 14 on the right side, so that the third spring 13 on the right side is reset and drives the arc plate 14 on the right side to reset. At this time, the third spring 13 on the right side is reset and drives the rotating frame 6 to slide and reset in the middle annular manner. The rotating frame 6 drives the limit frame 10 and the second spring 11 to move synchronously. When the limit frame 10 moves to the middle slot 12, under the action of the second spring 11, the limit frame 10 is stuck in the middle slot 12.

[0037] In this way, after detecting the side point position on one side, the rotating frame 6, the electric push rod 7 and the pressing frame 8 and other components will automatically return to the middle quickly, thereby shortening the time for detecting the side point position on the other side and improving the efficiency of multi-point detection.

[0038] Embodiment 2: Based on embodiment 1, Figure 8 To Attachment Fig. 9 , also includes a slide 19, the slide 19 is slidably connected to the support frame 2, the bottom of the slide 19 is in contact with the pressure frame 8, a fifth spring 191 is fixed between the slide 19 and the support frame 2 and is symmetrically distributed along the slide 19, the workbench 1 is slidably connected to the pull frame 20 along the front and rear directions, the pull frame 20 is limited by the slide 19 through the inclined groove, the workbench 1 is slidably connected to the baffle 21 for limiting the bearing seat during testing in the up and down directions, and the pull frame 20 is squeezed and matched with the baffle 21.

[0039] When the pressure frame 8 applies downward pressure to the bearing seat, the fifth spring 191 in the compressed state resets and drives the slide 19 to slide downward. The slide 19 squeezes the pull frame 20 to slide backward through the inclined groove, thereby squeezing the baffle 21 to slide upward and block the front side of the bearing seat to prevent the bearing seat from sliding forward at will during pressure testing, thereby avoiding affecting the test results. When the pressure frame 8 slides upward and resets, the pressure frame 8 drives the slide 19 to slide upward and reset, the fifth spring 191 is compressed, and the slide 19 drives the pull frame 20 to slide forward through the inclined groove. The baffle 21 is embedded downward into the workbench 1 under the action of gravity, and does not affect the removal of the bearing seat after the test.

[0040] Embodiment 3: Based on Embodiment 2, Fig.10 , also includes a sensor 22, the sensor 22 is fixedly connected to the arc plate 14 on the rear side, and the arc plate 14 on the front side is fixedly connected to a sensing switch 23. When adjacent arc plates 14 are close to each other, adjacent sensors 22 contact the sensing switches 23. The front side of the support frame 2 is fixedly connected to warning lights 24 symmetrically distributed along the left and right sides of the support frame 2. When the left and right warning lights 24 are on at the same time, it means that the left and right side points of the bearing seat have completed the test, and the sensing switch 23 is electrically connected to the warning light 24 on the same side through the control module.

[0041] After the middle point is detected, since the points on the left and right sides need to be detected separately, the detection personnel are prone to memory confusion after testing multiple bearing seats for a long time, which leads to forgetting whether the other side is detected after testing one side, resulting in re-inspection or missed inspection. To avoid this phenomenon, the specific operation is as follows: When one side of the bearing seat is detected, the arc plates 14 on the same side move closer to each other, and the third spring 13 on the same side is reset to drive the rotating frame 6 to slide back to the middle ring. At this time, the induction switch 23 on the same side contacts the adjacent sensor 22, controlling the warning light 24 on the same side to light up for 5 seconds. Within 5 seconds, the other side of the bearing seat is also detected and lit. The warning lights 24 on the left and right sides are lit at the same time, which means that the left and right side points of the bearing seat have completed the test.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
