Description

Technical Field

[0001] This utility model relates to the field of bearing processing equipment technology, and in particular to a demagnetizing mechanism for a bearing processing production line. Background Technology

[0002] As a high-precision basic mechanical component, bearings often develop residual magnetism during manufacturing processes such as grinding and turning due to the use of electromagnetic chucks or the inherent properties of the material. This residual magnetism attracts ferromagnetic particles from the production environment, such as metal dust and grinding debris. Once these contaminants enter the bearing, they severely affect its rotational accuracy, increase operating noise and friction, and ultimately shorten its service life. Therefore, effective demagnetization treatment before finished or semi-finished bearings enter subsequent processes is an indispensable and crucial step in ensuring their final quality.

[0003] In existing automated production lines, a common demagnetizing method involves placing the demagnetizing mechanism, such as a demagnetizing coil, directly above a continuously running conveyor belt. The bearing moves at a constant speed through the demagnetizing field area with the conveyor belt to complete the demagnetization. However, because the conveyor belt runs continuously, the residence time of the bearing in the demagnetizing field depends entirely on the conveyor belt speed. In pursuit of production efficiency, the conveyor belt speed is usually relatively high, which results in the bearing having too short an effective magnetic field period. This leads to insufficient correction and disturbance of magnetic domains, easily causing incomplete demagnetization.

[0004] Furthermore, since the bearing simply "passes through" the magnetic field on the conveyor belt, it is difficult to ensure that the exposure time and intensity of different parts of the bearing in the magnetic field are completely uniform. This further leads to the problem of uneven demagnetization, which means that some areas of the bearing may still retain strong residual magnetism, failing to fundamentally solve the quality problems caused by residual magnetic tape.

[0005] Therefore, this utility model proposes a demagnetizing mechanism for a bearing processing production line to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing bearing processing production line demagnetizing mechanism, such as short demagnetizing time and uneven effect of bearings during continuous movement, resulting in incomplete and uneven demagnetization, as well as lack of automated cleaning function, this utility model aims to provide a demagnetizing mechanism for bearing processing production line with improved structure that can achieve precise positioning demagnetization and automated cleaning.

[0007] This utility model provides a demagnetizing mechanism for a bearing processing production line, including: a support table, a control box, a conveyor belt, a sensor, and a demagnetizing mechanism body spanning above the conveyor belt; it also includes a support plate fixed to the support table and a lifting assembly disposed on the support plate.

[0008] The lifting assembly includes an electric push rod, a protective shell, a baffle, an outer shell, and a limiting plate; the top of the support plate has an elongated groove, the outer shell has a slot, and the outer side of the baffle has a sliding column.

[0009] Furthermore, the electric push rod is fixed to the support plate and its push rod output end is connected to the protective shell; the limiting plate is set at the bottom of the protective shell and slides in cooperation with the elongated groove; the outer shell is fixed inside the protective shell; the sliding column slides in cooperation with the groove. Through the linkage of this series of structures, the horizontal movement of the electric push rod is converted into the vertical lifting and lowering movement of the baffle.

[0010] Preferably, the sensor is located at the outlet of the demagnetizing mechanism body along the conveyor belt conveying direction.

[0011] Preferably, the slot is an inclined slot to achieve stable motion conversion.

[0012] Preferably, limit blocks are symmetrically arranged on the outside of the baffle to stably clamp the intercepted bearing.

[0013] Preferably, the baffle is located on the downstream side of the demagnetizing mechanism body along the conveyor belt conveying direction.

[0014] Preferably, the demagnetizing mechanism for the bearing processing production line further includes a U-shaped frame, which is disposed above the end of the conveyor belt along its conveying direction.

[0015] Preferably, the U-shaped frame is provided with a soft brush.

[0016] Preferably, the demagnetizing mechanism for the bearing processing production line further includes a fan, which is located downstream of the soft brush along the conveyor belt conveying direction.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting up a lifting component, after the sensor detects the bearing position, uses the linkage of an electric push rod, protective shell, outer shell, baffle, sliding column and slot to lower the baffle to intercept and temporarily fix the bearing. This solves the problem in the prior art of incomplete and uneven demagnetization caused by the bearing moving continuously on the conveyor belt and not being able to stay in the demagnetizing field for a sufficient time. It achieves the technical effect of accurately positioning the bearing inside the demagnetizing mechanism body for all-round and full demagnetization, significantly improving the demagnetization quality and product qualification rate.

[0018] 2. This utility model solves the problem that when a bearing is intercepted by the baffle, it may shift laterally or rotate due to the continuous friction of the conveyor belt, thus deviating from the optimal demagnetization position. By symmetrically setting limiting blocks on the baffle, this invention achieves the technical effect of stable clamping and secondary limiting of the bearing, further ensuring the stability and reliability of the demagnetization process.

[0019] 3. This utility model solves the problem that metal shavings or dust may adhere to the bearings during demagnetization or conveying, affecting subsequent processing or product cleanliness, by adding a U-shaped frame at the end of the conveyor belt and integrating a soft brush and a fan on the U-shaped frame. It achieves the technical effect of automatically cleaning and blowing the demagnetized bearings, ensuring the cleanliness of the products and improving the automation integration of the production line.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Please refer to Figures 1 to 4This utility model provides a demagnetizing mechanism for a bearing processing production line, aiming to solve the technical problem of uneven and incomplete demagnetization of bearings during movement in existing bearing production lines. Figure 1 As shown, the demagnetizing mechanism for the bearing processing production line includes a support table 1 as the overall mounting base, a control box 2 for controlling the operation of the equipment is fixedly connected to the support table 1, and a conveyor belt 4 for conveying the bearings 5 ​​to be demagnetized is also provided on the support table 1. The demagnetizing mechanism body 3 is straddling the conveyor belt 4, and a sensor 6 is located at the exit of the demagnetizing mechanism body 3 along the conveyor belt 4. Specifically, please refer to Figure 1 , Figure 3 and Figure 4 The demagnetizing mechanism for the bearing processing production line also includes a support plate 8 fixedly connected to the support table 1, and a lifting assembly 9 set on the support plate 8. The lifting assembly 9 is used to intercept and limit the bearing 5 to be demagnetized on the conveyor belt 4 when the sensor 6 detects the bearing 5 to be demagnetized.

[0024] The structure of each component and its connection relationship are described in detail below: The top of the support plate 8 is provided with an elongated groove 906, which is used to guide the movement trajectory of the lifting assembly 9.

[0025] The lifting assembly 9 includes an electric push rod 901, a protective shell 902, a baffle 903, a housing 904, and a limiting plate 907. The body of the electric push rod 901 is fixedly connected to the support plate 8, and the push rod output end of the electric push rod 901 is fixedly connected to the protective shell 902, thereby providing driving force for the lifting assembly 9.

[0026] A limiting plate 907 is fixedly connected to the bottom of the protective shell 902. The limiting plate 907 is slidably engaged with the elongated groove 906 on the support plate 8. This slidable engagement restricts the movement of the protective shell 902 to linear reciprocating motion along the direction of the elongated groove 906.

[0027] The outer shell 904 is fixedly connected to the inside of the protective shell 902, so the outer shell 904 moves synchronously with the protective shell 902. A slot 905 is provided on the outer side wall of the outer shell 904. The slot 905 is an inclined slot used to convert horizontal movement into vertical movement.

[0028] The baffle 903 is located on the downstream side of the demagnetizing mechanism body 3 along the conveyor belt 4. A sliding column 908 is fixedly connected to the outer side of the baffle 903. The sliding column 908 slides in cooperation with the slot 905 on the outer shell 904. When the electric push rod 901 pushes the protective shell 902 and the inner outer shell 904 to slide horizontally along the elongated slot 906, the sliding column 908 slides in the inclined slot 905, thereby driving the baffle 903 to move up and down.

[0029] The electrical connection and control logic between the electric actuator 901, the control box 2, and the sensor 6 can be selected and configured by those skilled in the art as needed. This is a well-known technology in the field and will not be described in detail here.

[0030] As a preferred embodiment, in order to provide a more stable limit when intercepting the demagnetizing bearing 5 and prevent it from shifting or rotating under the friction of the conveyor belt 4, such as Figure 2 As shown, a limiting block 12 is symmetrically fixedly connected to the outside of the side of the baffle 903 facing the bearing 5 to be demagnetized. The limiting block 12 can effectively clamp the outer ring of the bearing 5 to be demagnetized of different specifications.

[0031] As another preferred embodiment, in order to clean the surface of the bearing 5 to be demagnetized after demagnetization and remove impurities adhering to its surface, such as... Figure 1 As shown, the equipment also includes a U-shaped frame 7, which is fixedly connected to the support table 1 and spans over the end of the conveyor belt 4 along its conveying direction.

[0032] Based on the above solution, in order to achieve physical brushing of the bearing, such as Figure 1 As shown, a soft brush 10 is fixedly connected to the U-shaped frame 7. The bristles of the soft brush 10 face the conveyor belt 4. When the bearing to be demagnetized 5 passes under it, the soft brush 10 can brush away impurities on its surface and the surface of the conveyor belt 4.

[0033] Furthermore, in order to blow clean the product after it has been cleaned by the soft brush 10, ensuring the product surface is clean, such as... Figure 1 As shown, the equipment also includes a fan 11, which is fixedly connected to the support table 1. Its air outlet is located downstream of the soft brush 10 along the conveyor belt 4 and faces the conveyor belt 4. The fan 11 is used to blow away the tiny impurities remaining on the surface of the bearing to be demagnetized 5 and the conveyor belt 4.

[0034] Working principle: When the demagnetizing mechanism of this utility model is working, the equipment is started through the control box 2. The bearing to be demagnetized 5 is placed on the conveyor belt 4. The conveyor belt 4 transports the bearing to be demagnetized 5 to the bottom of the demagnetizing mechanism body 3. When the bearing to be demagnetized 5 is about to completely pass through the demagnetizing mechanism body 3, the sensor 6 set at its outlet detects the position of the bearing to be demagnetized 5 and triggers the electric push rod 901 to move. The push rod output end of the electric push rod 901 extends and pushes the protective shell 902. The limiting plate 907 at the bottom of the protective shell 902 slides horizontally along the elongated groove 906 on the support plate 8. The outer shell 904 fixed inside the protective shell 902 also slides horizontally synchronously. At this time, the sliding column 908 fixed on the outside of the baffle 903 moves outward. The bearing slides within the inclined slot 905 on the shell 904. This sliding engagement converts the horizontal movement of the shell 904 into the vertical descent of the baffle 903. The baffle 903 descends to a position where it abuts against the outside of the bearing 5 to be demagnetized. At the same time, the limiting block 12 on it clamps and limits the bearing, thereby temporarily intercepting and fixing the bearing 5 to be demagnetized inside the demagnetizing mechanism body 3 for all-round demagnetization. After demagnetization is completed, the electric push rod 901 moves in the opposite direction, driving the baffle 903 to rise vertically, releasing the interception of the bearing. The conveyor belt 4 continues to transport the demagnetized bearing to the U-shaped frame 7. The bearing passes through the brush 10 on the U-shaped frame 7 and the blower 11 in sequence to remove surface impurities, completing the entire demagnetization and cleaning process.
