Description

[0002] During the production process of bearings, raw materials (bearing blanks) need to be transported. The transported raw materials will roll down an inclined plane to a stop station for screening. However, since the raw materials have been placed for a long time, rust will appear on the surface of the raw materials, resulting in the raw materials not being able to roll down the inclined plane at a uniform speed. The raw materials are likely to fall off the inclined plane before the stop station.

[0003] Therefore, in order to solve the technical problem that the stock raw materials are prone to fall off the rolling slope during transportation after rusting, it is necessary to design a new feeding equipment and production process for bearing production.

[0069] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0070] like Figure 1 As shown, in at least one disclosed embodiment, a feeding device for bearing production is provided, comprising: a control module, and a conveying device 1 and a unloading device 2 controlled by the control module; the unloading device 2 is arranged at the tail end of the conveying device 1 in the conveying direction; the control module is configured to control the conveying device 1 to convey the raw material it carries to the unloading device 2; the raw material is cylindrical; the control module is configured to control the rotation of the unloading device 2 so that the raw material rolls smoothly to the stop position provided on the unloading device 2; the unloading device 2 is regulated during the rolling process of the raw material to prevent the raw material from falling out of the unloading device 2.

[0071] like Figure 2As shown, in an optional embodiment, the blanking device 2 includes: a first blanking strip 21 and a second blanking strip 22; the first blanking strip 21 is rotatably connected to the corresponding support strip 11 in the conveying device 1; the second blanking strip 22 is rotatably connected to the corresponding support strip 11 in the conveying device 1; the first blanking strip 21 and the second blanking strip 22 are arranged in parallel, and the distance between the first blanking strip 21 and the second blanking strip 22 is less than the length of the raw material, ensuring that the raw material can be placed on the first blanking strip 21 and the second blanking strip 22; the first blanking strip 21 is connected to the corresponding first motor 211, the first motor 211 is arranged on the corresponding support strip 11, and the first motor 211 is suitable for driving the first blanking strip 21 to rotate; the second blanking strip 22 is connected to the corresponding second motor 221, The second motor 221 is arranged on the corresponding support bar 11, and the second motor 221 is suitable for driving the second material strip 22 to rotate; the first motor 211 and the second motor 221 are both electrically connected to the control module, and the control module is suitable for obtaining the torque of the first motor 211 and the second motor 221. The control module can obtain the torque through the corresponding torque sensor or voltage and current detection calculation; the raw material is guided by the inclined surfaces on the first and second material strips 21 and 22, so that the raw material rolls to the stop station, and the raw material can be screened at the stop station; the first motor 211 can drive the first material strip 21 to rotate, and the second motor 221 can drive the second material strip 22 to rotate, and the rotation direction is shown as F in the figure; the first motor 211 and the second motor 221 can directly use motors that can obtain their own torque.

[0072] In an optional embodiment, the top surfaces of the first blanking strip 21 and the second blanking strip 22 are both inclined surfaces, and the closer the inclined surface is to the corresponding support strip 11, the higher the inclined surface is; a recess 23 is provided at the lowest point of the inclined surface of the first blanking strip 21 and the second blanking strip 22, and the two recesses 23 constitute a stop position; the raw material rolls down the inclined surface to the stop position.

[0073] In an optional embodiment, a first grating ruler is provided on the first blanking strip 21; a second grating ruler is provided on the second blanking strip 22; the first grating ruler and the second grating ruler are electrically connected to the control module; the first grating ruler is suitable for detecting a first distance moved by the raw material on the first blanking strip 21; the second grating ruler is suitable for detecting a second distance moved by the raw material on the second blanking strip 22; the control module is configured to compare the first distance with the second distance at a first preset time, and lift the first blanking strip 21 or the second blanking strip 22 corresponding to the larger value by a corresponding angle according to the absolute value of the difference between the two; since the friction force at the contact position between the raw material and the first blanking strip 21 will be different from the friction force at the contact position between the raw material and the second blanking strip 22, one end of the raw material will be closer to the stop position than the other end during the sliding process of the raw material. At this time, the first blanking strip 21 or the second blanking strip 22 needs to be adjusted, otherwise the raw material will slide off the first blanking strip 21 or the second blanking strip 22. Falling; the first preset time can be half of the time required for the standard raw material to roll along the first material strip 21 and the second material strip 22 to the stop position. For example, if the total rolling time of the standard raw material is 1.5S, the first preset time is 1S. After rolling for 1S, the first distance and the second distance are obtained. If the first distance is 1m and the second distance is 0.99m, it means that the position of the raw material on the first material strip 21 is closer to the stop position than the position of the raw material on the second material strip 22. At this time, the first material strip 21 needs to be turned upward and lifted to prevent the raw material from rolling down. The angle at which the first material strip 21 is lifted upward can be controlled according to the difference of 0.01m between the two, so that the angle to be lifted can be set according to actual experience. According to actual experience, the angle corresponding to the distance difference can be tabulated and stored. Each distance difference can correspond to a preset angle. After the difference is obtained, it is directly adjusted according to the preset angle corresponding to the difference to prevent the raw material from rolling down from the first material strip 21 and the second material strip 22.

[0074] In an optional embodiment, the control module is configured to obtain the first torque and the second torque when the raw material rolls to the stop position, and obtain the average value of the first torque and the second torque, and control the first motor 211 or the second motor 221 according to the difference between the average value and the preset torque standard value;

[0075] A≤[(T1+T2) / 2-T3]≤B;

[0076] Among them, T3 is the preset torque standard value, which can be 32N·M; A is the preset torque comparison range minimum value; B is the preset torque comparison range maximum value; B can be 2N·M, and A is -2N·M; when the difference between the average value and the preset torque standard value is greater than B, it is judged that the weight of the raw material is greater than the qualified weight. At this time, the control module controls the first motor 211 to drive the first unloading bar 21 to rotate upward, so that the raw material at the stop position slides from the outside of the second unloading bar 22; when the difference between the average value and the preset torque standard value is less than A, it is judged that the weight of the raw material is less than the qualified weight. At this time, the control module controls the second motor 221 to drive the second unloading bar 22 to rotate upward, so that the raw material at the stop position slides from the outside of the first unloading bar 21; the raw material that meets the standard can be pre-set. The quasi-weight raw material (standard raw material) is placed at the stop station, the first torque and the second torque are detected at this time, and the average value is obtained, and the average value is used as the preset standard value. When the actual average value of the first torque and the second torque is subtracted from the preset standard value, if the difference is within the preset comparison range, it is judged that the weight of the raw material at this time meets the requirements. If the difference is greater than the maximum value of the preset comparison range, the raw material is judged to be too heavy. If the difference is less than the maximum value of the preset comparison range, the raw material is judged to be too light. The overweight and underweight raw materials are screened by rotating the first feeding bar 21 and the second feeding bar 22, and the qualified raw materials can be grabbed from the stop station to the subsequent station by a robot arm, etc. According to the actual historical situation, T1 and T2 will not differ too much, for example, the difference between the two will not exceed 20.

[0077] like Figure 3 As shown, in an optional embodiment, the conveying device 1 includes: a pair of support bars 11; the support bars 11 are arranged in parallel, and the distance between the two support bars 11 is less than the length of the raw material; the tail end of one support bar 11 in the raw material transportation direction is rotatably connected to the first unloading bar 21, and the tail end of the other support bar 11 in the raw material transportation direction is rotatably connected to the second unloading bar 22; a plurality of support grooves 111 are equidistantly provided on the support bar 11 along the length direction of the support bar 11, and two support grooves 111 on the two support bars 11 that are perpendicular to the support bars 11 and on the same straight line constitute a support station; a support groove 111 is provided with a support A support assembly is provided, wherein the support assembly is suitable for supporting raw materials; a transport mechanism is provided between the two support bars 11, wherein the transport mechanism is suitable for transporting raw materials; the transport mechanism can lift the raw materials so that the raw materials are separated from the support bars 11, and then move the raw materials toward the feeding device 2, so that the raw materials are moved to above the next support station, at which time the transport mechanism descends, so that the raw materials enter the next support station, and the raw materials are transported to the feeding device 2 through the support stations one by one in a reciprocating cycle, and the raw materials at the last support station are lifted and moved to above the inclined surfaces of the first feeding bar 21 and the second feeding bar 22, and the raw materials are placed on the inclined surface when the transport mechanism descends to facilitate the rolling of the raw materials.

[0078] In an optional embodiment, the support assembly includes: a support block 12; the support block 12 is slidably connected to the side wall of the support groove 111, and the support block 12 is suitable for moving up and down in the support groove 111; the bottom surface of the support block 12 is connected to a lifting block 121 through a spring 123, and the lifting block 121 is slidably connected to the side wall of the support groove 111, and the lifting block 121 is suitable for moving up and down in the support groove 111; a V-shaped groove 122 is provided on the top surface of the support block 12, and the V-shaped groove 122 is suitable for supporting raw materials; in the initial position, the length direction of the first blanking strip 21 is in the same straight line as the length direction of the corresponding support strip 11, and the length direction of the second blanking strip 22 is in the same straight line as the length direction of the corresponding support strip 11; the inner wall of the V-shaped groove 122 is a polished surface; the width of the inner wall of the V-shaped groove 122 is greater than the width of the top surface of the first blanking strip 21 and the second blanking strip 22.

[0079] Since there may be rust on the surface of the raw material, the shape of the rust will cause the surface of the raw material to be deformed, so that the raw material cannot roll smoothly on the inclined surfaces of the first material strip 21 and the second material strip 22. Therefore, in the process of conveying the raw material by the conveying device 1, two positions on the raw material are polished through the contact between the raw material and the polishing surface. Since the width of the inner wall of the V-shaped through groove 122 is greater than the width of the top surface of the first material strip 21 and the second material strip 22, when the raw material is transported to the inclined surfaces of the first material strip 21 and the second material strip 22, the position where the inclined surface contacts the raw material is polished, which is convenient for the raw material to roll down. In addition, if the raw material cannot roll down at a uniform speed during the rolling process, that is, the raw material and the first material strip are not in contact, the raw material and the first material strip will not roll down smoothly. The speed of the contact position of the inclined surface 21 and the speed of the contact position of the raw material and the inclined surface of the second feed strip 22 are different. The contact position of the raw material and the inclined surface changes. Since the width of the grinding position on the raw material is greater than the width of the inclined surface, even if the position changes, it can be ensured that the contact position of the raw material and the inclined surface has been polished. The influence of rust on the rolling process of the raw material is reduced by grinding. The effects of grinding at two positions on the raw material may be different, resulting in the raw material being unable to roll down at a uniform speed during the process of rolling along the inclined surface. Therefore, the first feed strip 21 and the second feed strip 22 need to be adjusted during the rolling process of the raw material to prevent the raw material from falling from the first feed strip 21 and the second feed strip 22 during the process of rolling to the stop position.

[0080] like Figure 4As shown, in an optional embodiment, the transport mechanism includes: a drive component 13 controlled by the control module; a pair of transport bars 14 are arranged on the top surface of the drive component 13; a plurality of arc-shaped through grooves 141 are equidistantly provided on the top surface of the transport bar 14 along the length direction of the transport bar 14, and the raw material is supported by the arc-shaped through grooves 141 during the lifting process; the transport bar 14 is located between two support bars 11; the control module drives the transport bar 14 to move synchronously through the drive component 13 to transport the raw material; the drive component 13 makes the movement trajectory of the transport bar 14 approximate to a circle, so that the surface of the raw material can be more in contact with the polishing surface during the lifting process of the raw material by the transport bar 14, thereby ensuring the polishing effect.

[0081] like Figure 5 As shown, since the grinding effects of the two positions on the raw material on the corresponding grinding surfaces are inconsistent, it is necessary to adjust the height of the support block 12 to adjust the grinding effect so that the grinding effects of the two positions on the raw material are close or the same; in the process of the raw material rolling down the inclined surface, the control module will record the number of rotations of the first material strip 21 and the second material strip 22. If it is determined that the first material strip 21 needs to rotate upward during the rolling of the raw material, the first material strip 21 will be recorded to rotate once. When the number of times needs to be recorded during the rolling process of the same raw material, it will only be recorded once; a movable plate 15 is provided on one side of the support bar 11, and the movable plate 15 is connected to a driving motor 151. The driving motor 151 can make the movable plate 15 move along the length direction of the support bar 11. A protrusion 152 corresponding to the lifting block 121 is provided on the side wall of the movable plate 15, and the top surface of the protrusion 152 is an inclined surface, and an inclined surface is also provided on the bottom surface of the lifting block 121. The inclined surface can be provided on the extension portion of the lifting block 121 so that the inclined surface is located at the support The support groove 111 is supported outside so that the inclined surface of the bottom surface of the lifting block 121 can contact the inclined surface of the top surface of the protrusion 152. When the grinding effect needs to be increased, the control module controls the driving motor 151 to drive the moving plate 15 to move, and the lifting block 121 is lifted upward by the inclined surface of the protrusion 152 and the inclined surface of the lifting block 121, so that the support block 12 moves upward, so that the contact time between the raw material and the grinding surface during the transportation process is increased, so as to increase the grinding effect; | t1-t2 | ≥ t3, where t1 is The first material strip 21 rotates times, t2 is the number of times the second material strip 22 rotates, t3 is a preset comparison value, and the specific value may be 5. When the absolute value is greater than the preset comparison value, it is determined that the grinding effect needs to be adjusted. If t1 is greater than t2, it means that the grinding effect of the grinding surface on the support bar 11 corresponding to the first material strip 21 is better. At this time, the control module controls the moving plate 15 on the side of the support bar 11 corresponding to the second material strip 22 to move, so that the support block 12 on the support bar 11 moves upward to increase the grinding effect.

[0082] In an optional embodiment, the transport bar 14 lifts the raw material above the top surface of the support bar 11 during the upward movement, the transport bar 14 moves forward to move the raw material above the next support station, and the transport bar 14 moves downward to place the raw material in the support station.

[0083] At least one disclosed embodiment also provides a production process using the above-mentioned loading equipment for bearing production, including: a control module controls the conveying device 1 to transport the raw materials it carries to the unloading device 2; the control module controls the rotation of the unloading device 2 to allow the raw materials to roll smoothly to the stop position provided on the unloading device 2.

[0084] In summary, the feeding equipment for bearing production includes: a control module, and a conveying device 1 and a unloading device 2 controlled by the control module; the unloading device 2 is arranged at the tail end of the conveying device 1 in the conveying direction; the control module is configured to control the conveying device 1 to convey the raw materials it carries to the unloading device 2; the control module is configured to control the rotation of the unloading device 2 so that the raw materials can roll smoothly to the stop position provided on the unloading device 2; the unloading device 2 is regulated during the rolling process of the raw materials to prevent the raw materials from falling out of the unloading device 2.
