Description

Technical Field

[0001] The present invention belongs to the field of nut production, and particularly relates to an efficient centrifugal degreasing method and device for fastening nuts. Background Art

[0002] During the production of fastening nuts, a large amount of oil stains will remain on their surfaces. If not removed, it will cause pollution, and at the same time, it will make it difficult to stack and store the fastening nuts, and will also affect the use experience.

[0003] A common method for degreasing fastening nuts is to perform degreasing by centrifugation. The fastening nuts are placed on a centrifugal device, and the oil stains on the fastening nuts are separated by centrifugal force. The existing centrifugal devices usually place the fastening nuts on the centrifugal device and rotate them at a certain speed for a certain period of time. This method has the following defects: First, the oil stains on the fastening nuts have been removed, but the centrifugal device is still performing centrifugal degreasing treatment on the fastening nuts, resulting in energy waste; Second, the oil stains on the fastening nuts have not been completely removed, but the set centrifugation time has reached, resulting in incomplete removal of the oil stains on the fastening nuts. Summary of the Invention

[0004] The main purpose of the present invention is to provide an efficient centrifugal degreasing method and device for fastening nuts, which are used to solve the two defects of the existing centrifugal devices for degreasing fastening nuts mentioned in the background art.

[0005] To achieve the above object, the present invention provides an efficient centrifugal degreasing method for fastening nuts, which includes:

[0006] Step S1: Receive the fastening nuts to be processed that need to be centrifugally degreased;

[0007] Step S2: Measure and determine the mass of the fastening nuts to be processed, and judge the magnitude between the mass of the fastening nuts to be processed and a preset standard value;

[0008] If the mass of the fastening nuts to be processed measured and determined is greater than or equal to the preset standard value, then execute Step S3: Calculate the difference between the mass of the fastening nuts to be processed and the preset standard value, and determine the initial rotation speed n0 for centrifugally degreasing the fastening nuts to be processed according to the magnitude of the difference;

[0009] Step S4: Monitor the mass change rate a1 when the fastening nuts to be processed are centrifugally degreased;

[0010] Step S5: Change the rotation speed n1 for centrifugally degreasing the fastening nuts to be processed according to the mass change rate a1.

[0011] When the oil stain on the fastening nut is removed, the mass of the fastening nut will change. According to the mass change rate a1 of the fastening nut, the rotation speed n1 during the centrifugal oil removal treatment of the fastening nut to be processed is adjusted accordingly. When the mass of the fastening nut no longer changes, it can be considered that the oil stain on the fastening nut has been removed. At this time, changing the rotation speed n1 to 0 can stop the oil removal treatment of the fastening nut, so that energy is no longer wasted. When the mass of the fastening nut is still changing, the rotation speed n1 will be adjusted in real time to perform the oil removal treatment on the fastening nut, thereby effectively reducing the occurrence of incomplete oil stain removal on the fastening nut.

[0012] As a further preferred technical solution of the above technical solution, the mass change rate a1 is equal to the difference between the mass M0 of the fastening nut to be processed at the moment T0 before the preset time period t and the mass M1 of the fastening nut to be processed at the current time point T1, divided by the preset time period t.

[0013] As a further preferred technical solution of the above technical solution, the rotation speed n1 during the centrifugal oil removal treatment of the fastening nut to be processed is positively correlated with the mass change rate a1. When the value of the mass change rate a1 becomes smaller, it indicates that the amount of oil stain that can be removed from the fastening nut to be processed becomes less. At this time, the rotation speed n1 for the centrifugal oil removal treatment of the fastening nut to be processed can be reduced to reduce energy consumption. When the value of a1 is zero, it indicates that the mass of the fastening nut to be processed does not change during the time period t, so it can be considered that the oil stain on the fastening nut to be processed has been completely removed. At this time, the treatment of the fastening nut to be processed can be stopped, thus avoiding energy waste.

[0014] As a further preferred technical solution of the above technical solution, after performing the step S5, it further includes:

[0015] Step S6: Determine the value of the rotation speed n1. When the rotation speed n1 is less than the threshold value, set the rotation speed during the centrifugal oil removal treatment of the fastening nut to be processed to 0;

[0016] If the mass of the fastening nut to be processed is within the preset error range of the preset standard value at this time, then perform step S7, otherwise perform step S8; Step S7: Unload the fastening nut to be processed;

[0017] Step S8: Send the fastening nut to be processed into the waste part box and issue an error alarm.

[0018] When the rotational speed n1 is less than the threshold value, it indicates that the mass change rate a1 has met the requirements, that is, it can be considered that the oil stain on the fastening nut to be processed has been removed. If the mass of the fastening nut to be processed is not within the preset error range of the preset standard value at this time, it means that the fastening nut to be processed does not meet the production specification requirements. Therefore, the fastening nut to be processed needs to be sent to the waste bin for scrapping.

[0019] As a further preferred technical solution of the above technical solution, after the step S2, if the measured and determined mass of the fastening nut to be processed is less than the preset standard value, it jumps to the step S8. After the step S2, when the measured mass of the fastening nut to be processed is less than the preset standard value, it means that the fastening nut to be processed does not meet the production specification requirements. Therefore, the fastening nut to be processed needs to be sent to the waste bin for scrapping.

[0020] The present invention also provides a high-efficiency centrifugal oil removal device for fastening nuts, which is used to execute any one of the above high-efficiency centrifugal oil removal methods for fastening nuts. The high-efficiency centrifugal oil removal device for fastening nuts includes a centrifugal rotating rod, a weighing instrument, and a processor;

[0021] The centrifugal rotating rod is used to receive the fastening nut to be processed that needs to be centrifugally oil-removed;

[0022] The weighing instrument is installed in the base of the centrifugal rotating rod, and the weighing instrument is used to measure and determine the mass of the fastening nut to be processed;

[0023] The processor is used to receive the mass of the fastening nut to be processed measured by the weighing instrument, and judge the magnitude between the mass of the fastening nut to be processed and the preset standard value; if the measured and determined mass of the fastening nut to be processed is greater than or equal to the preset standard value, calculate the difference between the mass of the fastening nut to be processed and the preset standard value, and determine the initial rotational speed n0 of the centrifugal rotating rod according to the magnitude of the difference;

[0024] The processor is also used to calculate the mass change rate a1 of the fastening nut to be processed during centrifugal oil removal according to the mass of the fastening nut to be processed determined by the weighing instrument in real time, and change the rotational speed n1 of the centrifugal rotating rod according to the mass change rate a1.

[0025] When the oil stain on the fastening nut is removed, the quality of the fastening nut will change. According to the mass change rate a1 of the fastening nut, the rotation speed n1 of the fastening nut to be processed during centrifugal degreasing is adjusted accordingly. When the mass of the fastening nut no longer changes, it can be considered that the oil stain on the fastening nut has been removed. At this time, changing the rotation speed n1 to 0 can stop the degreasing process of the fastening nut, so that energy is no longer wasted. When the mass of the fastening nut is still changing, the rotation speed n1 will be adjusted in real time to degrease the fastening nut, thus effectively reducing the occurrence of incomplete removal of the oil stain on the fastening nut.

[0026] As a further preferred technical solution of the above technical solution, the device further includes a timing device, the timing device is connected to the processor, and the processor is further configured to receive the time information recorded by the timing device; the mass change rate a1 is equal to the difference between the mass M0 of the fastening nut to be processed at the moment T0 before the preset duration t and the mass M1 of the fastening nut to be processed at the current time point T1 divided by the preset duration t.

[0027] As a further preferred technical solution of the above technical solution, the rotation speed n1 of the centrifugal rod is positively correlated with the mass change rate a1.

[0028] As a further preferred technical solution of the above technical solution, the device further includes a waste part box and an alarm device; the processor is further configured to determine the value of the rotation speed n1 of the centrifugal rod. When the rotation speed n1 is less than the threshold value, the rotation speed of the centrifugal rod is set to 0; if the mass of the fastening nut to be processed is within the preset error range of the preset standard value at this time, the processor controls the centrifugal rod to unload the fastening nut to be processed; otherwise, the processor controls the centrifugal rod to send the fastening nut to be processed into the waste part box and controls the alarm device to give an error alarm. If the mass of the fastening nut to be processed is not within the preset error range of the preset standard value at this time, it means that the fastening nut to be processed does not meet the production specification requirements. Therefore, the fastening nut to be processed needs to be sent to the waste part box for scrapping.

[0029] As a further preferred technical solution of the above technical solution, the processor is further configured to control the centrifugal rod to send the fastening nut to be processed into the waste part box and control the alarm device to give an error alarm when the measured and determined mass of the fastening nut to be processed is less than the preset standard value. The mass of the fastening nut to be processed being less than the preset standard value indicates that the fastening nut to be processed does not meet the production specification requirements. Therefore, the fastening nut to be processed needs to be sent to the waste part box for scrapping. Description of the Drawings

[0030] Figure 1It is a schematic flow chart of an efficient centrifugal degreasing method for fastening nuts provided by the present invention;

[0031] Figure 2 It is a schematic structural diagram of a possible efficient centrifugal degreasing device for fastening nuts provided by the present invention. Detailed implementation manners

[0032] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variants. The basic principles defined in the following description of the present invention can be applied to other implementation manners, variants, improvements, equivalent manners, and other technical solutions without departing from the spirit and scope of the present invention.

[0033] Refer to the Figure 1 , Figure 1 It is a schematic flow chart of an efficient centrifugal degreasing method for fastening nuts provided by the present utility model. As Figure 1 shown, the efficient centrifugal degreasing method for fastening nuts provided by the present utility model includes:

[0034] Step S1: Receive the fastening nut to be processed that needs to be centrifugally degreased;

[0035] In this step, the centrifugal rotating rod for centrifugation of the device that executes the efficient centrifugal degreasing method for fastening nuts can receive the fastening nut to be processed from the automatic feeding module of the device, or an operator can manually load the fastening nut to be processed onto the centrifugal rotating rod of the device. The present invention does not specifically limit how the fastening nut to be processed in step S1 is loaded, and various existing feeding methods can be used to complete the loading.

[0036] Step S2: Measure and determine the mass of the fastening nut to be processed, and judge the size between the mass of the fastening nut to be processed and a preset standard value;

[0037] The mass of the fastening nut to be processed includes the mass of the fastening nut itself and the mass of the oil stain on the fastening nut to be processed; the preset standard value is the mass standard of a qualified part of the fastening nut without oil stain set in advance.

[0038] If the mass of the fastening nut to be processed measured and determined is greater than or equal to the preset standard value, then execute step S3: Calculate the difference between the mass of the fastening nut to be processed and the preset standard value, and determine the initial rotation speed n0 when centrifugally degreasing the fastening nut to be processed according to the size of the difference;

[0039] The greater the difference between the quality of the fastening nut to be processed and the preset standard value, the greater the quality of the oil stain on the fastening nut to be processed. Therefore, in order to efficiently remove the oil stain on the fastening nut to be processed, the larger the initial rotation speed n0 needs to be set.

[0040] Step S4: Monitor the mass change rate a1 of the fastening nut to be processed during the centrifugal oil removal process;

[0041] Step S5: According to the mass change rate a1, change the rotation speed n1 of the fastening nut to be processed during the centrifugal oil removal process.

[0042] When the oil stain on the fastening nut is removed, the mass of the fastening nut will change. According to the mass change rate a1 of the fastening nut, the rotation speed n1 of the fastening nut to be processed during the centrifugal oil removal process is adjusted accordingly. When the mass of the fastening nut no longer changes, it can be considered that the oil stain on the fastening nut has been removed. At this time, changing the rotation speed n1 to 0 can stop the oil removal process of the fastening nut, so that energy is no longer wasted. When the mass of the fastening nut is still changing, the rotation speed n1 is adjusted in real time to carry out the oil removal process of the fastening nut, thereby effectively reducing the occurrence of incomplete removal of the oil stain on the fastening nut.

[0043] As a further preferred technical solution of the above technical solution, the mass change rate a1 is equal to the difference between the mass M0 of the fastening nut to be processed at the moment T0 before the preset time period t and the mass M1 of the fastening nut to be processed at the current time point T1 divided by the preset time period t.

[0044] Of course, during the centrifugal oil removal process, the rotation speed n1 of the fastening nut to be processed will affect the measured mass of the fastening nut to be processed. Therefore, further, the measured mass of the fastening nut to be processed can be corrected in combination with the current rotation speed n1 of the fastening nut to be processed. Specifically, the mass correction carried out at each rotation speed needs to be formulated according to the actual specifications of the fastening nut to be processed.

[0045] As a further preferred technical solution of the above technical solution, the rotation speed n1 of the fastening nut to be processed during the centrifugal oil removal process is positively correlated with the mass change rate a1.

[0046] The decrease in the value of the mass change rate a1 indicates that the amount of oil stain that can be removed on the fastening nut to be processed becomes less. At this time, the rotation speed n1 of the fastening nut to be processed for oil removal can be reduced to reduce energy consumption. When the value of a1 is zero, it indicates that the mass of the fastening nut to be processed no longer changes within the time period t, so it can be considered that the oil stain on the fastening nut to be processed has been completely removed. At this time, the processing of the fastening nut to be processed can be stopped, thus avoiding energy waste.

[0047] When the value of the mass change rate a1 changes at a relatively small mass change rate a1, the change in the rotational speed n1 is relatively large at this time; when the value of the mass change rate a1 changes at a relatively large mass change rate a1, the change in the rotational speed n1 is relatively small at this time. This is because when the remaining amount of oil stain on the fastening nut to be processed is small, the value of the mass change rate a1 will be relatively small at this time, and the rotational speed n1 still needs to maintain the basic rotational speed required for centrifugal degreasing.

[0048] As a further preferred technical solution of the above technical solution, after performing the step S5, it further includes:

[0049] Step S6: Determine the value of the rotational speed n1. When the rotational speed n1 is less than the threshold value, set the rotational speed for centrifugal degreasing the fastening nut to be processed to 0; if the mass of the fastening nut to be processed is within the preset error range of the preset standard value at this time, perform step S7, otherwise perform step S8; Step S7: Unload the fastening nut to be processed;

[0050] Step S8: Send the fastening nut to be processed into the waste part box and issue an error alarm.

[0051] The rotational speed n1 is less than the threshold value, indicating that the mass change rate a1 has met the requirements, that is, it can be considered that the oil stain on the fastening nut to be processed has been removed. If the mass of the fastening nut to be processed is not within the preset error range of the preset standard value at this time, it means that the fastening nut to be processed does not meet the production specification requirements. Therefore, the fastening nut to be processed needs to be sent into the waste part box for scrapping. That is, the mass of the fastening nut to be processed within the preset error range of the preset standard value indicates that the fastening nut to be processed is a qualified part, otherwise it is a non-qualified part.

[0052] As a further preferred technical solution of the above technical solution, after the step S2, if the measured and determined mass of the fastening nut to be processed is less than the preset standard value, jump to the step S8. After the step S2, the measured mass of the fastening nut to be processed is less than the preset standard value, indicating that the fastening nut to be processed does not meet the production specification requirements. Therefore, the fastening nut to be processed needs to be sent into the waste part box for scrapping.

[0053] The high-efficiency centrifugal degreasing device for fastening nuts provided by the present invention adjusts the rotational speed required for centrifugal degreasing in real time according to the mass of the fastening nut to be processed. When the mass of the fastening nut to be processed no longer changes or the change amount is small enough to be considered that the oil stain has been removed, the centrifugal degreasing process is stopped, thereby reducing energy waste. When the mass of the fastening nut to be processed is still changing, that is, the oil stain has not been completely removed, the rotational speed is adjusted in real time to perform centrifugal degreasing on the fastening nut to be processed, reducing the possibility that the oil stain on the fastening nut to be processed is not completely cleaned.

[0054] Based on the above high-efficiency centrifugal degreasing method for fastening nuts, the present invention further provides a high-efficiency centrifugal degreasing device for fastening nuts.

[0057] The processor is used to receive the mass of the fastening nuts to be processed measured by the weighing instrument, and judge the magnitude between the mass of the fastening nuts to be processed and a preset standard value; if the mass of the fastening nuts to be processed measured and determined is greater than or equal to the preset standard value, then calculate the difference between the mass of the fastening nuts to be processed and the preset standard value, and determine the initial rotation speed n0 of the centrifugal rotating rod according to the magnitude of the difference;

[0058] The processor is also used to calculate the mass change rate a1 of the fastening nuts to be processed during centrifugal degreasing treatment according to the mass of the fastening nuts to be processed determined in real time by the weighing instrument, and change the rotation speed n1 of the centrifugal rotating rod according to the mass change rate a1.

[0059] When the oil stains on the fastening nuts are removed, the mass of the fastening nuts will change. According to the mass change rate a1 of the fastening nuts, the rotation speed n1 of the fastening nuts to be processed during centrifugal degreasing treatment is adjusted accordingly. When the mass of the fastening nuts no longer changes, it can be considered that the oil stains on the fastening nuts have been removed. At this time, changing the rotation speed n1 to 0 can stop the degreasing treatment of the fastening nuts, so that energy is no longer wasted. And when the mass of the fastening nuts is still changing, the rotation speed n1 will be adjusted in real time to perform degreasing treatment on the fastening nuts, thereby effectively reducing the occurrence of incomplete removal of the oil stains on the fastening nuts.

[0061] As a further preferred technical solution of the above technical solution, the rotation speed n1 of the centrifugal rotating rod is positively correlated with the mass change rate a1.

[0062] As a further preferred technical solution of the above technical solution, the device further includes a waste part box and an alarm device; the processor is further configured to determine the value of the rotation speed n1 of the centrifugal rotating rod, and when the rotation speed n1 is less than a threshold value, set the rotation speed of the centrifugal rotating rod to 0; if at this time the mass of the fastening nut to be processed is within the preset error range of the preset standard value, control the centrifugal rotating rod to discharge the fastening nut to be processed; otherwise, control the centrifugal rotating rod to send the fastening nut to be processed into the waste part box and control the alarm device to give an error alarm. If the mass of the fastening nut to be processed is not within the preset error range of the preset standard value at this time, it means that the fastening nut to be processed does not meet the production specification requirements. Therefore, it is necessary to send the fastening nut to be processed into the waste part box for scrapping.

[0063] As a further preferred technical solution of the above technical solution, the processor is further configured to control the centrifugal rotating rod to send the fastening nut to be processed into the waste part box and control the alarm device to give an error alarm when the measured and determined mass of the fastening nut to be processed is less than the preset standard value. The mass of the fastening nut to be processed being less than the preset standard value indicates that the fastening nut to be processed does not meet the production specification requirements. Therefore, it is necessary to send the fastening nut to be processed into the waste part box for scrapping.

[0064] The working principle and effect of this high-efficiency centrifugal degreasing device for fastening nuts are the same as those described in the foregoing high-efficiency centrifugal degreasing method for fastening nuts, and reference can be made to the relevant descriptions in the foregoing method, which will not be elaborated here.

[0065] The following is a possible implementation manner of this high-efficiency centrifugal degreasing device for fastening nuts provided by the present invention, with reference to the attached drawings Figure 2 , Figure 2 is a schematic structural diagram of a possible high-efficiency centrifugal degreasing device for fastening nuts provided by the present utility model. As shown in Figure 2 , the degreasing device includes a housing 1, a centrifugal rotating rod 2, a rotating rod 3, a mounting seat 4, a finished product box 5, and a waste part box 6;

[0066] Both sides of the housing 1 bulge upward. The rotating rod 3 is connected between the bulges on both sides of the housing 1. The mounting seat 4 is installed on the rotating rod 3.

The finished product box 5 is arranged on the front side of the depression between the bulges on both sides of the housing 1, and the waste part box 6 is arranged on the rear side of the depression between the bulges on both sides of the housing 1.
