Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing detection, in particular to a pre-grinding detection device for a bearing outer ring. Background Art

[0002] Bearings are one of the most important and indispensable components in mechanical equipment. Their quality directly affects the working efficiency and service life of the mechanical equipment. As an important component of bearings, the outer ring of the bearing needs to go through multiple processes during the production process, including grinding. To ensure the quality of the outer ring of the bearing, it is usually strictly inspected before grinding to detect and eliminate unqualified products in a timely manner.

[0003] During the rotation detection process of the existing detection device, the bearing may fall off the detection platform due to the centrifugal force generated during the rotation, thereby resulting in poor detection effect. Utility Model Content

[0004] The present invention aims to solve the problems existing in the prior art and proposes the following technical solutions:

[0005] The pre-grinding detection device for the outer ring of a bearing includes a base plate, a bracket installed on the upper end of the base plate, a detection device installed inside the bracket, a turntable installed on the base plate, and a supporting plate installed on the turntable. An inner column is fixedly installed on the top of the supporting plate; and a clamping member is installed on the side wall of the inner column through an elastic mechanism.

[0006] Under the limiting clamping action of the clamping member, the limiting operation of the bearing is completed from the inner ring of the bearing, so that the main bearing to be inspected can be stably mounted on the bearing plate, completing the inspection operation of the inspected device.

[0007] As a preferred embodiment of the above technical solution, the elastic mechanism includes an inner groove opened on the side wall of the inner column, and a limiting groove is opened on the inner wall of the inner groove, a sliding rod is installed in the limiting groove, and the outer walls of the sliding rods are slidably connected to the sliders, and the outer walls of the two groups of sliders are connected by elastic parts, the middle part of the elastic part surrounds the outer wall of the sliding rod, the outer wall of the slider is movably connected to the support part, and the outer side of the support part is movably connected to the inner wall of the clamping part.

[0008] When the bearing needs to be limited, the sliding action of the slide rod and the slider and the elastic potential energy of the elastic part will move the clamping part toward the inner column. At this time, the inner ring of the bearing is sleeved on the outer wall of the clamping part in accordance with the special shape of the clamping part as shown in the figure. After the bottom end of the bearing contacts the surface of the load-bearing plate, the clamping part is released. With the elastic potential energy of the elastic part and the supporting effect of the support part, the limiting operation of the bearing can be completed from the inside of the bearing.

[0009] As a preferred embodiment of the above technical solution, an abutment pad is installed on the outer wall of the clamping member.

[0010] Under the protective effect of the abutment pad, the outer wall of the clamping part is prevented from direct contact with the inner wall of the bearing inner ring, and the damage to the bearing inner ring caused by scratches caused by direct contact during the detection process is avoided. At the same time, under the use of the abutment pad, the friction between the clamping part and the bearing inner ring is increased, further improving the stability efficiency of the limit.

[0011] As a preferred embodiment of the above technical solution, a ball is rotatably embedded in the bottom end of the clamping member, and the bottom end of the ball rolls in a slide rail, and the slide rail is provided on the bearing plate.

[0012] The rolling action between the balls and the slide rails reduces the friction between the clamping member and the bearing plate during movement, thereby making the movement of the clamping member smoother and more efficient.

[0013] The beneficial effects of the utility model are:

[0014] In this application, with the cooperation of the limiting mechanism, the bearing is limited and clamped from the inside, so that when the outer ring of the bearing is inspected, the limit is sufficiently stable, and the elastic parts inside the limiting mechanism are cooperated to complete the stable limiting operation of the bearing, thereby ensuring the inspection effect.

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] This application addresses the problem in the prior art that due to the centrifugal force generated during rotation, the bearing may fall off the detection platform, thereby resulting in poor detection effect. With the cooperation of the limiting mechanism, the bearing is limited and clamped from the inside, so that when the outer ring of the bearing is tested, the limit is sufficiently stable, and the elastic part 11 inside the limiting mechanism is cooperated to complete the stable limiting operation of the bearing, thereby ensuring the detection effect.

[0022] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the bearing outer ring pre-grinding detection device includes a base plate 1, a bracket 2 installed on the upper end of the base plate 1, a detection device 3 installed inside the bracket 2, a turntable 4 installed on the base plate 1, and a supporting plate 5 installed on the turntable 4; in the prior art, the detection operation of the bearing outer ring placed on the supporting plate 5 is completed by the detection device 3 installed in the bracket 2, and the detection device 3 is provided with a visual detection system, which is installed just above the supporting plate 5 and consists of a high-resolution camera, a light source and an image processing computer. The camera is responsible for capturing the image of the surface of the bearing outer ring, and the light source is used to provide uniform lighting conditions to ensure image quality; at the same time, the detection device 3 is also provided with a visual detection system. An automatic positioning mechanism is provided: for accurately controlling the position of the outer ring of the bearing, ensuring that the outer ring of the bearing is in the same position each time it is tested, which is convenient for comparative analysis; a control system is also provided: integrated in the detection device, for controlling various operations during the detection process, such as the rotation of the outer ring of the bearing, image acquisition, etc., and processing the collected data to determine whether the outer ring of the bearing is qualified; and an alarm and recording module is provided: when unqualified products are detected, the device will sound an alarm and record relevant information of the unqualified products for easy traceability; the bearing for detection on the supporting plate 5 is rotated under the action of the turntable 4 to be detected, which is well known to those skilled in the art and will not be elaborated in this application.

[0023] like Figure 2 and Figure 3 As shown, an inner column 6 is fixedly installed on the top of the carrying plate 5; and a clamping member 13 is installed on the side wall of the inner column 6 through an elastic mechanism; under the limiting clamping action of the clamping member 13, the limiting operation of the bearing is completed from the inner ring of the bearing, so that the main bearing to be tested can be stably installed on the carrying plate 5, and the detection operation of the detected device 3 is completed; the elastic mechanism includes an inner groove 7 opened on the side wall of the inner column 6, and a limiting groove 8 is opened on the inner wall of the inner groove 7, a slide bar 9 is installed in the limiting groove 8, and the outer wall of the slide bar 9 is slidably connected to the slider 10, and the outer walls of the two groups of sliders 10 are connected by an elastic member 11, and the middle part of the elastic member 11 surrounds the outer wall of the slide bar 9. The outer wall of the slider 10 is movably connected to the support member 12, and the outer side of the support member 12 is movably connected to the inner wall of the clamping member 13; when the bearing needs to be limited, the sliding action of the slide bar 9 and the slider 10 and the elastic potential energy of the elastic member 11 inwardly move the clamping member 13 toward the inner column 6. At this time, in conjunction with Figure 2 The special shape of the clamping member 13 shown is used to fit the inner ring of the bearing onto the outer wall of the clamping member 13. After the bottom end of the bearing contacts the surface of the load-bearing plate 5, the clamping member 13 is released. With the elastic potential energy of the elastic member 11 and the supporting effect of the support member 12, the bearing limiting operation can be completed from the inside of the bearing.

[0024] like Figure 1 、 Figure 2 and Figure 3 As shown, an abutment pad 14 is installed on the outer wall of the clamping member 13; under the protective effect of the abutment pad 14, the outer wall of the clamping member 13 is prevented from direct contact with the inner wall of the bearing inner ring, and the situation of damage to the bearing inner ring caused by scratches due to direct contact during the detection process is avoided. At the same time, under the use of the abutment pad 14, the friction between the clamping member 13 and the bearing inner ring is increased, and the stability efficiency of the limit is further improved; a ball 15 is rolled and embedded in the bottom end of the clamping member 13, and the bottom end of the ball 15 rolls in the slide rail 16, and the slide rail 16 is opened on the bearing plate 5; under the coordinated use of the rolling action between the ball 15 and the slide rail 16, the friction generated between the clamping member 13 and the bearing plate 5 during the movement is reduced, so that the movement of the clamping member 13 is smooth and efficient.
