Description

Technical Field

[0001] The utility model relates to the technical field of deburring machines, in particular to an automatic turning and cleaning mechanism for a deburring machine. Background Art

[0002] During the deburring process, the workpiece is usually loaded and unloaded through a material frame. Currently, some deburring machines can achieve full automation of loading and unloading.

[0003] Some deburring machines fail to clean impurities from the frame during the conveying process. Currently, this process relies mainly on manual cleaning with a handheld air gun, which is quite cumbersome. Failure to clean the impurities from the frame can easily result in the finished product being mixed with the impurities. This can cause the workpiece to be improperly assembled during the subsequent assembly process, affecting the precision and quality of the finished product, and ultimately, the quality of the product being shipped.

[0004] Therefore, the present application proposes an automatic flipping and cleaning mechanism for a deburring machine that has good cleaning effect on impurities in the material frame. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an automatic flipping and cleaning mechanism for a deburring machine, which solves the problem that impurities in the material frame are not cleaned and easily affect the delivery quality.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an automatic flipping and cleaning mechanism for a deburring machine, comprising:

[0007] A turning frame, the turning frame being rotatably connected to a conveyor table of the deburring machine;

[0008] A conveying unit, the conveying unit being arranged between the left and right inner side walls of the turning frame;

[0010] The support plate is fixedly connected to the conveyor platform of the deburring machine, the turning frame is rotatably connected between the two support plates, and the rotating shaft of the turning frame is also meshed with a motor through a transmission chain;

[0011] At least two material frame fixing mechanisms are provided, and each of them comprises a base rod and a support frame fixedly connected to the base rod;

[0012] The material frame blocking mechanism is also included, and the material frame blocking mechanism is arranged on the front side of the turning frame.

[0013] It also includes a position contact, which is arranged on the front side of the blocking mechanism of the flip rack loading frame, and the position contact includes an infrared transmitter and an infrared receiver arranged opposite to each other;

[0014] Among them, when the material frame C passes through the position contact, the infrared ray is blocked and the infrared receiver cannot receive the infrared ray. When the material frame C completely passes through the position contact, the infrared receiver receives the infrared ray again, thereby sending a signal. The controller receives the signal and controls the flip rack to clean the next material frame C, including the extension of the lifting cylinder, the operation / stop of the electric roller, the forward and reverse rotation of the motor, and the operation of the material frame fixing mechanism.

[0015] Preferably, the support frame in at least one of the material frame fixing mechanisms is a long rod, and the long rod is fixed at the middle position of the base rod;

[0016] The support frame in the other material frame fixing mechanism is a short rod, and the two short rods in each material frame fixing mechanism are respectively fixed at the left and right edges of the base rod.

[0017] Preferably, the supports in all the material frame fixing mechanisms are short rods, and the two short rods in each material frame fixing mechanism are respectively fixed at the left and right edges of the base rod.

[0018] Preferably, a guide mechanism is further provided at the top of the front end of the turnover frame, and the guide mechanism includes a spring hinge and a roller rotatably connected to the free end of the spring hinge.

[0019] Preferably, the conveying unit includes several motorized rollers.

The top height of the limit column is aligned with the horizontal height of the rotation axis of the turning frame, and an eccentric limit plate is also provided on the side of the turning frame close to the limit column.

[0021] Preferably, a detection contact and a buffer head are fixedly mounted on each of the limit columns.

[0022] Compared with the prior art, the present invention provides an automatic flipping and cleaning mechanism for a deburring machine, which has the following beneficial effects:

[0023] The automatic flipping and cleaning mechanism for the deburring machine flips the material frame about 180 degrees during the process of conveying the empty material frame, so that impurities in the material frame can be thoroughly cleaned, avoiding the presence of debris in the material frame causing the workpiece after deburring to be stuck with impurities when placed in the material frame, and preventing the workpiece from being assembled in place later, which affects the delivery quality.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] See also Figure 1-3The utility model provides the following technical solutions: an automatic turning and cleaning mechanism for a deburring machine, comprising a turning frame 1, a conveying unit 2, a material frame fixing mechanism 3, a support plate, a material frame blocking mechanism and a position contact; the turning frame 1 is rotatably connected to the conveyor table A of the deburring machine; the conveying unit 2 is arranged between the left and right inner walls of the turning frame 1; the material frame fixing mechanisms 3 are both rotatably connected between the two inner walls of the turning frame 1 and are located above the conveying unit 2; the support plates 1-2 are fixedly connected to the conveyor table A of the deburring machine, the turning frame 1 is rotatably connected between the two support plates 1-2, and the rotating shaft of the turning frame 1 is also meshed with a motor 9 through a transmission chain 8; at least two material frame fixing mechanisms 3 are provided, and both include a base rod 4 and a resisting frame 5 fixedly connected to the base rod 4; it also includes a material frame blocking mechanism 6, the material frame blocking mechanism Mechanism 6 is arranged on the front side of the turning frame 1; the material frame blocking mechanism 6 includes a lifting cylinder and a baffle, the baffle is fixedly connected to the ejection end of the lifting cylinder, and the cylinder is fixedly connected to the crossbeam 1-1 at the lower front side of the turning frame 1; it also includes a position contact 7, the position contact 7 is arranged on the front side of the material frame blocking mechanism 6 of the turning frame 1, and the position contact 7 includes an infrared transmitter and an infrared receiver arranged opposite to each other; wherein, when the material frame C passes through the position contact 7, the infrared ray is blocked and the infrared receiver cannot receive the infrared ray. When the material frame C completely passes through the position contact 7, the infrared receiver receives the infrared ray again, thereby sending a signal. The controller receives the signal and controls the turning frame 1 to perform the cleaning work of the next material frame C, including the extension of the lifting cylinder, the operation / stop of the electric roller, the forward and reverse rotation of the motor 9, and the operation of the material frame fixing mechanism 3.

[0032] As an optional implementation scheme of the present invention, a channel for the material frame C to pass through is formed in the turning frame 1, and the conveying unit 2 provides support for the material frame C and driving force through the turning frame 1. When the material frame C enters the turning frame 1, the base rod 4 in the material frame fixing mechanism 3 rotates, driving the abutment 5 to rotate and finally abutting against the material frame C, thereby fixing the material frame C in the turning frame 1, preventing the material frame C from falling when the turning frame 1 is turned over. When the turning frame 1 rotates, it drives the material frame C to rotate synchronously so that impurities in the material frame C can fall out, thereby achieving the cleaning of the material frame C, avoiding the presence of debris in the material frame C causing the workpiece after deburring to be stuck with impurities when placed in the material frame C, and preventing the subsequent assembly of the workpiece from being in place, which affects the quality of shipment. In addition, this cleaning method can make the impurities in the material frame C be cleaned more thoroughly.

[0033] When the motor 9 is running, it can drive the turning frame 1 to rotate forward or reverse, thereby realizing the turning of the turning frame 1. Other ways can also be used to make the turning frame 1 rotate, which is not limited in this embodiment.

[0034] After the material frame C enters the turning frame 1 or the last material frame C that has been cleaned is moved out of the turning frame 1, the material frame C in the turning frame 1 can be blocked by the operation of the material frame blocking mechanism 6. On the one hand, it has the effect of positioning the material frame C, ensuring that the material frame C can be fixed by the material frame fixing mechanism 3. On the other hand, when the material frame C is fixed by the material frame fixing mechanism 3, it is flipped approximately at the midline position along its own length direction, so that the impurities that fall out will accurately fall into the hopper B in the conveyor platform A without being scattered everywhere.

[0035] When the lifting cylinder is in operation, it drives the baffle to extend and retract, thereby blocking or releasing the front end of the material frame C. In this embodiment, the lifting cylinder can also be set at the upper part of the front end of the material frame C, or a rotary cylinder can be used to drive the baffle. The advantage of setting the lifting cylinder at the front end of the turning frame 1 in this embodiment is that it does not require a large space, ensuring that the gap between the turning and cleaning mechanism and the next process is not too large, causing the entire conveyor line to be sparse and affecting the movement of the material frame C.

[0036] like Figure 2-3 As shown, the support frame 5 in at least one of the material frame fixing mechanisms 3 is a long rod 5-1, and the long rod 5-1 is fixed to the middle position of the base rod 4;

[0037] The support frame 5 in the other material frame fixing mechanism 3 is a short rod 5 - 2 , and the two short rods 5 - 2 in each material frame fixing mechanism 3 are fixed at the left and right edges of the base rod 4 respectively.

[0038] As an optional implementation scheme of the present invention, after the base rod 4 in one material frame fixing mechanism 3 rotates, the short rod 5-2 clamps the top edge of the material frame C, and after the base rod 4 in the other material frame fixing mechanism 3 rotates, the long rod 5-1 clamps the bottom of the material frame C. This method of fixing the material frame C is more suitable for the case where the material frame C has a detachable carrying tray. When fixing the material frame C, it can not only fix the material frame C but also fix the carrying tray in the material frame C, thereby preventing the tray from falling out when the turning rack 1 is turned over. After the material frame C is cleaned, the base rods 4 in all the material frame fixing mechanisms 3 rotate, so that all the support racks 5 rotate out of the range of the material frame C, ensuring that the subsequent movement of the material frame C out of the turning rack 1 will not be hindered.

[0039] In this embodiment, the number of long rods 5-1 or short rods 5-2 on each base rod 4 can be determined according to the situation. In this application, it is preferred that two long rods 5-1 or two short rods 5-2 are respectively carried on each base rod 4. If the width of the material frame C is large, the number of long rods 5-1 can be increased to ensure sufficient supporting force. Similarly, the number of material frame fixing mechanisms 3 can also be increased accordingly.

[0040] like Figure 2-3As shown, a guide mechanism 14 is further provided at the top of the front end of the turnover frame 1. The guide mechanism 14 includes a spring hinge 14-1 and a roller 14-2 rotatably connected to the free end of the spring hinge 14-1.

[0041] As an optional implementation scheme of the present invention, the spring hinge 14-1 can be installed on the crossbeam 1-1 at the upper front end of the turning frame 1. When the material frame C moves out of the turning frame 1, if the front end of the material frame C is tilted, it will contact the spring hinge 14-1. The elasticity of the spring hinge 14-1 prevents the material frame C from tilting excessively and thus smoothly enters the next workstation. Combined with the roller 14-2, the movement of the material frame C is smoother.

[0042] like Figure 3 As shown, the conveying unit 2 includes several motorized rollers.

[0043] As an optional implementation scheme of the present invention, the advantage of using a motorized roller is that impurities can pass through the gaps between each motorized roller and fall smoothly into the hopper B below the turning frame 1. Even if impurities fall on the motorized roller, they can continue to fall due to the rotation of the motorized roller. Compared with conveyor belts, conveyor chains and other methods, this conveying method makes it easier to collect and process the cleaned impurities.

[0044] like Figure 3 As shown, it also includes a limit column 10, and the two limit columns 10 are respectively arranged on the front and rear sides of the rotation axis of the turning frame 1, and are fixedly connected to the conveyor platform A of the deburring machine. The top height of the limit column 10 is aligned with the horizontal height of the rotation axis of the turning frame 1, and an eccentric limit plate 11 is also provided on the side of the turning frame 1 close to the limit column 10.

[0045] As an optional implementation scheme of the present invention, when the turning frame 1 turns over or rotates, such two limit columns 10 can allow the turning frame 1 to rotate about 180 degrees, which can not only ensure the cleaning effect of impurities, but also enable the turning frame 1 to be in a horizontal state when not turned over, and remain parallel to the conveying unit 2 of the previous and next processes, ensuring that the material frame C moves more smoothly in the previous and next processes.

[0046] like Figure 3 As shown, a detection contact 12 and a buffer head 13 are fixedly mounted on each limiting column 10 .

[0047] As an optional implementation scheme of the present invention, the buffer head 13 can use an elastic component to block the limit plate 11 on the flip frame 1 to prevent the flip frame 1 from being damaged by a large collision with the limit column 10 or the detection contact 12. The detection contact 12 is used to detect whether the limit plate 11 is in contact with the limit column 10, thereby ensuring that the flip angle of the flip frame 1 meets the standard and thus ensuring the cleaning effect of impurities. After the flip frame 1 is flipped into place, the detection contact 12 is squeezed and sends a signal, and the controller controls the motor 9 to rotate according to the signal. In this implementation scheme, the detection contact 12 and the buffer head 13 are both relatively mature existing technologies on the market, and this technical method does not make specific limitations or excessive elaboration.

[0048] Example 2:

[0049] Specifically, the supports 5 in all the material frame fixing mechanisms 3 are short rods 5 - 2 , and the two short rods 5 - 2 in each material frame fixing mechanism 3 are fixed at the left and right edges of the base rod 4 , respectively.

[0050] As another optional implementation scheme of the present invention, when there is no detachable carrier tray in the material frame C, or the carrier position is integrally formed with the material frame C, all the material frame fixing mechanisms 3 can also be used to fix the top edge of the material frame C, so that the adaptability of this cleaning mechanism is stronger.

[0051] The working principle and usage process of the utility model are as follows: after the material frame C in the turning frame 1 is cleaned, it is transported to the next process by the electric roller. After the position contact 7 detects that the material frame C has been completely sent out, the controller controls the lifting cylinder to push out the baffle, and at the same time the electric roller sends the empty material frame C in the previous process into the internal space of the turning frame 1. The rotating cylinder in the material frame fixing mechanism 3 drives the base rod 4 to rotate, so that the short rod 5-2 is against the top of the left and right edges of the material frame C, and the long rod 5-1 is against the bottom surface of the inner part of the material frame C. Then the motor 9 is started, causing the turning frame 1 to turn 180 degrees, and the impurities inside the material frame C fall out. Then the motor 9 rotates, all the base rods 4 rotate, the lifting cylinder descends, and the electric roller restarts to bring the empty material frame C to the next process.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
