Description

Technical Field

[0001] The invention relates to the technical field of spring processing, and in particular to an anti-deviating tool for processing high-strength butterfly springs. Background Art

[0002] The butterfly spring is an elastic element with unique structure and performance, which is widely used in the field of mechanical engineering. It is usually made of high-strength spring steel or stainless steel, in the shape of a conical disc, and is processed by stamping and forming. Its main feature is that it has a variable stiffness characteristic, that is, when it is deformed by force, the stiffness will gradually increase with the increase of deformation. It can withstand a large load under a small deformation. At the same time, the structure is compact and occupies a small space. The butterfly spring is widely used in clutches, brakes, shock absorbers, aerospace equipment, automotive suspension systems and other fields. Due to its high stiffness, high fatigue life and corrosion resistance, it is particularly suitable for use in places where space is limited or performance requirements are high. During installation and use, it is necessary to pay attention to the installation of guide parts to prevent lateral slippage, and to carry out proper lubrication, while avoiding exceeding the design load range to ensure its performance and service life.

[0003] In the prior art, the offset problem is a serious challenge in the processing of butterfly springs. Due to its butterfly structure and the existence of the center hole, the butterfly spring is prone to positional offset during stamping, forming and other links. This offset not only reduces the processing accuracy and affects the accuracy of its size and shape, but may also cause damage to the inner diameter of the center hole, thereby affecting the assembly accuracy and sealing performance. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose an anti-deviating tool for processing high-strength butterfly springs.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: an anti-deviation tooling for high-strength butterfly spring processing, comprising a base plate and a processing seat mounted on the base plate, the processing seat is fixedly mounted with a controller; a support block is mounted on the processing seat, the top of the support block is connected with a cover box with a downward opening, the top of the cover box is provided with a lower tooling die to provide support for the bottom end of the butterfly spring, a push rod capable of vertically passing through the central circular hole of the butterfly spring and limiting it is slidably provided at the top center of the lower tooling die, a plurality of monitoring units for monitoring whether the butterfly spring is deviated are provided on the outer wall of the push rod, and a retraction mechanism for protecting the butterfly spring when it is deviated under force is provided between the push rod and the inside of the cover box;

[0006] A power frame is fixedly connected to the top of the processing seat, and a multi-stage telescopic rod is installed between the power frame and the processing seat. A power mechanism is arranged inside the power frame, and a down-pressing rod is arranged on the power frame. The power mechanism provides corresponding power to the down-pressing rod. The end of the down-pressing rod is connected to a down-pressing piece matched with the top rod, and the butterfly spring is processed by the down-pressing piece.

[0007] Preferably, the retraction mechanism includes a top tube with an opening facing downward, the end of the top tube is fixedly connected to the top surface of the support block, the end of the top tube is slidably provided with a sliding rod connected to the bottom end of the top rod, and the diameter of the sliding rod is smaller than the diameters of the top rod and the top tube, the top end of the top tube is fixedly connected to an elastic telescopic rod, the telescopic end of the elastic telescopic rod is equipped with a hanging plate connected to the end of the top rod, and a rigid support mechanism is provided between the top rod and the sliding tube.

[0008] Preferably, the rigid support mechanism includes a transmission rod, a through hole and an electric push rod, the transmission rod is fixedly connected to the bottom end of the top rod, the through hole is opened on the top tube, the fixed part of the electric push rod is fixedly connected to the side wall of the cover box, the telescopic end of the electric push rod is fixedly connected to a connecting block, the bottom surface of the connecting block is fixedly connected to the top holding rod, and the diameter of the through hole is greater than or equal to the diameter of the transmission rod.

[0009] Specifically, the contraction of the electric push rod is controlled to drive the connecting block to move, and the connecting block drives the supporting rod to move. The supporting rod will leave the through hole and become gradually exposed. As the connecting block separates from the transmission rod, the transmission rod that loses the support of the connecting block will, under the action of the elastic telescopic rod, on the one hand, pull the top rod downward, so that the top rod is separated from the butterfly spring. On the other hand, when the transmission rod moves downward with the top rod, it will enter the interior of the through hole.

[0010] Preferably, the diameter of the supporting rod is larger than the diameter of the through hole, so that the supporting rod cannot directly pass through the through hole due to the size difference.

[0011] Preferably, a sliding roller used in conjunction with the conveying rod is rotatably provided on the top surface of the connecting block, and the sliding roller contacts the end of the conveying rod.

[0012] Preferably, the outer wall of the top rod is provided with a soft sleeve with an opening facing downward, and the hanging plate is fixed to the bottom surface of the soft sleeve.

[0013] The present invention, through the provision of a soft sleeve, firstly, helps to reduce possible damage to the butterfly spring; secondly, the deformation and displacement of the soft sleeve can buy time for the elastic telescopic rod to pull the push rod to separate from the butterfly spring; thirdly, the push rod is disposed inside the soft sleeve, and because it does not contact the push rod when separating, the push rod is more likely to slide toward the inside of the cover box, which helps to reduce the damage caused by mutual friction after the push rod and the butterfly spring come into contact.

[0014] Preferably, a first cavity is opened inside the top rod, and a plurality of first adsorption ports connected to the first cavity are opened at the end of the top rod, a second cavity is opened inside the conveying rod, and the second cavity is connected to the first cavity, a fan is fixedly installed on the outer surface of the top cylinder, and the cover box is provided with distribution holes that enable air flow.

[0015] Preferably, a second adsorption opening is provided on the outer wall of the push rod, and the second adsorption opening is used to adsorb the inner wall of the soft sleeve when the push rod moves downward.

[0016] Preferably, the monitoring unit comprises a plurality of mounting grooves and a plurality of pressure sensors, the mounting grooves are formed on the outer wall of the push rod, and the pressure sensors are installed inside the mounting grooves.

[0017] Preferably, the lower pressing member comprises a connecting seat, which is fixedly mounted on the bottom end of the lower pressing rod, and an upper tooling die used in conjunction with the lower tooling die is fixedly mounted on the bottom of the connecting seat.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides a retraction mechanism. When the butterfly spring is offset, the support for the push rod is released through the intervention of the retraction mechanism, and the push rod is quickly driven to move toward the inside of the cover box, which is beneficial for timely separation of the two after the center circular hole of the butterfly spring is stressed, thereby protecting the butterfly spring and improving the yield rate.

[0020] 2. The present invention arranges a soft sleeve on the outer wall of the push rod so that the soft sleeve contacts the central circular hole of the butterfly spring, and after the contact, even if the butterfly spring contacts the soft sleeve, it can give way by generating deformation. On the first hand, it is helpful to reduce possible damage to the butterfly spring. On the second hand, the deformation and giving way of the soft sleeve can buy time for the elastic telescopic rod to pull the push rod and the butterfly spring to separate. On the third hand, the push rod is arranged inside the soft sleeve, and because it does not contact the push rod when separating, the push rod is easier to slide into the inside of the cover box, which is helpful to reduce the damage caused by mutual friction after the push rod and the butterfly spring come into contact.

[0021] 3. The present invention sets a fan and a first adsorption port, and controls the fan to start. The fan discharges the air inside the top cylinder to the outside and flows out through the emission hole. After the transmission rod enters the inside of the through hole, an adsorption path such as top cylinder-second cavity-first cavity-first adsorption port is formed. At this time, a negative pressure space is formed at the first adsorption port. Because the top of the soft sleeve is sealed as a whole, the first adsorption port adsorbs the inside of the soft sleeve and causes the soft sleeve to deform, which is conducive to the separation of the soft sleeve from the top rod and the subsequent removal of the butterfly spring.

DETAILED DESCRIPTION

[0031] 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 described below are only examples, and those skilled in the art may think of other obvious variations.

[0032] Application scenarios: During the processing of butterfly springs, the offset problem is a serious challenge. Due to its disc-shaped structure and the existence of the center hole, the butterfly spring is prone to positional offset during stamping and forming. This offset will not only reduce the processing accuracy and affect the accuracy of its size and shape, but if the limit part contacts the center hole, it may also cause damage to the inner diameter of the center hole, thereby affecting the assembly accuracy and sealing performance.

[0033] like Figures 1 to 8 The anti-deviating tooling for processing high-strength butterfly springs shown in the figure comprises a base plate 1 and a processing seat 2 mounted on the base plate 1, the processing seat 2 is fixedly mounted with a controller 30; a support block 3 is mounted on the processing seat 2, the top of the support block 3 is connected with a cover box 4 with a downward opening, the top of the cover box 4 is provided with a lower tooling die 5 for providing support for the bottom end of the butterfly spring, a push rod 6 which can vertically pass through the central circular hole of the butterfly spring and limit it is slidably provided at the top center of the lower tooling die 5, a plurality of monitoring units for monitoring whether the butterfly spring is deviated are provided on the outer wall of the push rod 6, and a retraction mechanism for protecting the butterfly spring when it is deviated under force is provided between the push rod 6 and the inside of the cover box 4;

[0034] A power frame 7 is fixedly connected to the top of the processing seat 2, and a multi-stage telescopic rod 31 is installed between the power frame 7 and the processing seat 2. A power mechanism is arranged inside the power frame 7, and a down-pressing rod 8 is arranged on the power frame 7. The power mechanism provides corresponding power to the down-pressing rod 8. The end of the down-pressing rod 8 is connected to a down-pressing piece that cooperates with the top rod 6, and the butterfly spring is processed by the down-pressing piece.

[0035] It should be understood that during the processing of the butterfly spring, the butterfly spring to be processed must first be placed on the lower tooling die 5, and the central circular hole of the butterfly spring must be passed through the push rod 6. With the support of the push rod 6, the butterfly spring can be firmly limited to prevent it from shifting. Under normal processing conditions, the lower pressing piece will exert downward pressure on the butterfly spring, thereby pushing it into the processing link. However, during the processing, the butterfly spring may shift after being stressed, and at this time, the push rod 6 will play a key role in effectively limiting the butterfly spring that may shift, preventing it from causing processing failure due to the shift, which is conducive to ensuring the stability and reliability of the entire processing process.

[0036] When the butterfly spring is offset, although the sliding can be restricted by the push rod 6, in the actual processing process, the center circular hole of the butterfly spring may be damaged after contacting the push rod 6, thereby affecting the quality of the butterfly spring. Therefore, a monitoring unit is set on the outer wall of the push rod 6. During the processing, if the butterfly spring does not contact the push rod 6, it means that the processing is proceeding normally. If the monitoring unit detects pressure information, it means that the butterfly spring has been offset during the processing. In order to prevent the offset from causing damage to the center circular hole of the butterfly spring, the retraction mechanism will intervene to release the support for the push rod 6 and quickly drive the push rod 6 to move toward the inside of the cover box 4, which is beneficial for the two to be separated in time after the center circular hole of the butterfly spring is subjected to force, thereby protecting the butterfly spring and improving the yield rate.

[0037] As a further embodiment of the present invention, the retraction mechanism includes a top tube 9 with an opening facing downward, the end of the top tube 9 is fixedly connected to the top surface of the support block 3, the end of the top tube 9 is slidably provided with a sliding rod 10 connected to the bottom end of the top rod 6, and the diameter of the sliding rod 10 is smaller than the diameters of the top rod 6 and the top tube 9, the top end of the top tube 9 is fixedly connected with an elastic telescopic rod 11, the telescopic end of the elastic telescopic rod 11 is installed with a hanging plate 12 connected to the end of the top rod 6, and a rigid support mechanism is provided between the top rod 6 and the sliding tube.

[0038] It should be understood that the push rod 6 is supported by the rigid support mechanism. When its intervention is needed, the rigid support mechanism is controlled to start working, and the rigid support mechanism will release the support for the push rod 6. At this time, under the action of the elastic telescopic rod 11, the push rod 6 will be pulled along the lower tooling mold 5 to slide toward the inside of the cover tube, thereby separating the push rod 6 from the center circular hole of the butterfly spring, which is beneficial to prevent the butterfly spring from being damaged by force.

[0039] As a further implementation scheme of the present invention, the rigid support mechanism includes a transmission rod 13, a through hole 14 and an electric push rod 15. The transmission rod 13 is fixedly connected to the bottom end of the top rod 6. The through hole 14 is opened on the top tube 9. The fixed part of the electric push rod 15 is fixedly connected to the side wall of the cover box 4. The telescopic end of the electric push rod 15 is fixedly connected to a connecting block 16. The bottom surface of the connecting block 16 is fixedly connected to a supporting rod 17. The diameter of the through hole 14 is greater than or equal to the diameter of the transmission rod 13.

[0040] It should be understood that by controlling the contraction of the electric push rod 15 to drive the connecting block 16 to move, the connecting block 16 drives the supporting rod 17 to move, and the supporting rod 17 will leave the through hole 14 and make it gradually exposed. As the connecting block 16 is separated from the transmission rod 13, the transmission rod 13 that has lost the support of the connecting block 16, under the action of the elastic telescopic rod 11, on the one hand, pulls the top rod 6 downward, so that the top rod 6 is separated from the butterfly spring, and on the other hand, when the transmission rod 13 moves downward with the top rod 6, it will enter the interior of the through hole 14.

[0041] As a further embodiment of the present invention, the diameter of the supporting rod 17 is larger than the diameter of the through hole 14 , and the supporting rod 17 cannot directly pass through the through hole 14 due to the size difference.

[0042] It should be understood that by setting the diameter of the supporting rod 17 to be larger than the diameter of the through hole 14 in the initial state, it is convenient for the supporting rod 17 to provide supporting force.

[0043] As a further embodiment of the present invention, a sliding roller 18 is rotatably provided on the top surface of the connecting block 16 for use with the conveying rod 13 , and the sliding roller 18 contacts the end of the conveying rod 13 .

[0044] It should be understood that by adding a sliding roller 18 to the top surface of the rectangular block, the contact surface between the sliding roller 18 and the conveying rod 13 is converted from static friction to rolling friction, which is conducive to faster separation of the rectangular block from the conveying rod 13; similarly, a roller with the same function as the sliding roller 18 can be added to the end of the supporting rod 17, so that the supporting rod 17 can quickly slide out from the top surface of the hanging drum.

[0045] As a further embodiment of the present invention, the outer wall of the top rod 6 is provided with a soft cover 19 with an opening facing downward, and the hanging plate 12 is fixed to the bottom surface of the soft cover 19 .

[0046] It should be understood that in order to prevent the push rod 6 from being damaged by friction with the butterfly spring when it moves with the elastic telescopic rod 11, a soft sleeve 19 is sleeved on the outer wall of the push rod 6 so that the soft sleeve 19 is in contact with the central circular hole of the butterfly spring, and after the contact, even if the butterfly spring is in contact with the soft sleeve 19, it can give way by producing deformation. On the first hand, it is helpful to reduce possible damage to the butterfly spring. On the second hand, the deformation and giving way of the soft sleeve 19 can buy time for the elastic telescopic rod 11 to pull the push rod 6 and the butterfly spring to separate. On the third hand, the push rod 6 is arranged inside the soft sleeve 19, and because it does not contact the push rod 6 when separating, the push rod 6 is easier to slide into the inside of the cover box 4, which is helpful to reduce the damage caused by mutual friction after the push rod 6 and the butterfly spring come into contact.

[0047] As a further implementation scheme of the present invention, a first cavity 20 is opened inside the top rod 6, and a plurality of first adsorption ports 21 connected to the first cavity 20 are opened at the end of the top rod 6, a second cavity 22 is opened inside the conveying rod 13, and the second cavity 22 is connected to the first cavity 20, a fan 23 is fixedly installed on the outer surface of the top tube 9, and a distribution hole 24 that enables air flow is provided on the cover box 4.

[0048] It should be understood that based on the above-mentioned embodiments, the friction damage between the top rod 6 and the central circular hole of the butterfly spring can be solved by adding a soft sleeve 19 to the outer wall of the top rod 6. Therefore, when the elastic telescopic rod 11 pulls the top rod 6 to move toward the inside of the cover box 4, the fan 23 is started by controlling the fan 23 to discharge the air inside the top tube 9 to the outside and flow out through the emission hole 24. After the transmission rod 13 enters the inside of the through hole 14, an adsorption path such as the top tube 9-the second cavity 22-the first cavity 20-the first adsorption port 21 will be formed. At this time, a negative pressure space is formed at the first adsorption port 21. Because the top of the soft sleeve 19 is sealed as a whole, the first adsorption port 21 will adsorb the inside of the soft sleeve 19 and cause the soft sleeve 19 to deform, which is beneficial to the separation of the soft sleeve 19 from the top rod 6 and the subsequent removal of the butterfly spring.

[0049] As a further embodiment of the present invention, a second suction port 25 is provided on the outer wall of the push rod 6 , and the second suction port 25 is used to suction the inner wall of the soft cover 19 when the push rod 6 moves downward.

[0050] It should be understood that by opening the second suction port 25 on the side wall of the push rod 6 and making the suction port of the second suction port 25 smaller than the first suction port 21, the inner wall of the soft cover 19 can be adsorbed when the first suction port 21 descends, so that the soft cover 19 is deformed, which is helpful to further prevent the soft cover 19 from adhering to the push rod 6.

[0051] As a further embodiment of the present invention, the monitoring unit includes a plurality of mounting grooves 29 and a plurality of pressure sensors 28 . The mounting grooves 29 are opened on the outer wall of the top rod 6 , and the pressure sensors 28 are installed inside the mounting grooves 29 .

[0052] It should be understood that by setting up the pressure sensor 28, when the pressure sensor 28 senses pressure information, it means that an offset occurs between the butterfly spring and the push rod 6. At this time, the controller 30 controls the electric push rod 15 to start working, wherein the number of mounting grooves 29 corresponds to the number of pressure sensors 28, and the opening position of the mounting grooves 29 is not restricted and can be opened according to actual needs.

[0053] As a further embodiment of the present invention, the lower pressing member includes a connecting seat 26 , which is fixedly mounted on the bottom end of the lower pressing rod 8 , and an upper tooling die 27 used in conjunction with the lower tooling die 5 is fixedly mounted on the bottom of the connecting seat 26 .

[0054] It should be understood that the butterfly spring can be processed by using the lower tooling die 5 in conjunction with the upper tooling die 27 .

[0055] Working principle of the present invention:

[0056] During the processing of the butterfly spring, the butterfly spring to be processed must first be placed on the lower tooling die 5, and the central circular hole of the butterfly spring must be passed through the push rod 6. With the support of the push rod 6, the butterfly spring can be firmly limited to prevent it from shifting. Under normal processing conditions, the lower pressure piece will exert downward pressure on the butterfly spring, thereby pushing it into the processing link. However, during the processing, the butterfly spring may shift after being stressed, and at this time, the push rod 6 will play a key role in effectively limiting the butterfly spring that may shift, preventing it from causing processing failure due to the shift, which is conducive to ensuring the stability and reliability of the entire processing process.

[0057] When the butterfly spring is offset, although the sliding can be restricted by the push rod 6, in the actual processing process, the center circular hole of the butterfly spring may be damaged after contacting the push rod 6, thereby affecting the quality of the butterfly spring. Therefore, a monitoring unit is set on the outer wall of the push rod 6. During the processing, if the butterfly spring does not contact the push rod 6, it means that the processing is proceeding normally. If the monitoring unit detects pressure information, it means that the butterfly spring has been offset during the processing. In order to prevent the offset from causing damage to the center circular hole of the butterfly spring, the retraction mechanism will intervene to release the support for the push rod 6 and quickly drive the push rod 6 to move toward the inside of the cover box 4, which is beneficial for the two to be separated in time after the center circular hole of the butterfly spring is subjected to force, thereby protecting the butterfly spring and improving the yield rate.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
