Description

Technical Field

[0001] The utility model relates to the technical field related to mechanical parts, and in particular to a positioning structure of a bending device for a mechanical part. Background Art

[0002] Mechanical parts are the basic elements that constitute the machine. When the machine is produced, in order to ensure the normal operation of the machine, the shapes of its basic elements will not all be regular shapes. In order to produce the mechanical parts into the corresponding shapes, the auxiliary work of the bending device is generally required. When the bending device is performing the bending work, the parts to be processed are generally transmitted to the bending position by the conveying device, and then the mechanical parts are positioned by the positioning structure. After that, the bending head is controlled to move downward, which will drive the mechanical parts to perform the bending work. The purpose of the positioning structure is to stably fix the mechanical parts in the position to be processed to ensure that the position of the mechanical parts will not be offset when the bending head is performing the downward impact bending. For example, the positioning bending mechanism for aluminum profile processing disclosed in application No. 202121208649.4 presses the parts through the movable rod 5. When it is necessary to control the movement of the workpiece, it is only necessary to control the electric telescopic rod to rise, and cooperate with the setting of the rubber roller to control the movement of the parts;

[0003] However, the above-mentioned positioning mechanism is only suitable for bending one side of a component. When a general factory bends a mechanical component, in order to ensure the bending efficiency, it usually bends all sides of the component on a bending machine. Since the bending angles and lengths on different sides are not fixed, when the bending angle and the bending length on the side are large, the electric telescopic rod in the comparison document needs to be moved up with a large displacement. When performing the large displacement upward movement, a lot of time will be wasted. In order to save processing time, the electric telescopic rod needs to be controlled to move to different degrees according to the different heights of different bent sides, which will bring difficulties to the subsequent control work.

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

[0030] See also Figure 1-6 The utility model provides a technical solution: a positioning structure of a mechanical parts bending device, including a transmission mechanism 1, a positioning structure is arranged at the top of the transmission mechanism 1, and the positioning structure includes:

[0031] The extrusion mechanism 2 is located at both sides of the top of the conveying mechanism 1. A driving mechanism 3 is also provided outside the top of the conveying mechanism 1. The top of the driving mechanism 3 is respectively connected to the extrusion mechanism 2 and the fixing mechanism 4, and the extrusion mechanism 2 squeezes the fixing mechanism 4 to complete the positioning work;

[0032] The utility model provides a novel positioning mechanism for a bending machine, which is composed of an extrusion mechanism 2 and a fixing mechanism 4 that cooperate to complete the positioning work. Figure 1-2 As shown, specifically, during operation, the external conveying mechanism 1 conveys the mechanical parts to be processed to the top end to be processed, and then the driving mechanism 3 and the extrusion mechanism 2 extrude the top end of the rotating fixing mechanism 4, so that the bottom of the fixing mechanism 4 completes the clamping work on the top end of the mechanical parts, and then the bending head at the top end of the mechanical parts moves downward to complete the bending work of the mechanical parts.

[0033] The conveying mechanism 1 is composed of two conveying rollers and a conveying belt, and the top of the conveying roller is rotated by the control of the servo motor. When the conveying roller rotates, it can drive the conveying belt to perform conveying work, which is used to convey mechanical parts. A support frame is also provided outside the conveying mechanism 1 for supporting the conveying mechanism 1. The inner side of the support frame is connected to the conveying roller on the conveying mechanism 1 through a bearing;

[0034] Specifically, when the servo motor is working, the conveying roller will rotate inside the support frame, so that the transmission belt will perform the conveying work, completing the effect of conveying the mechanical parts to be processed, so that they reach the position to be processed;

[0035] In this embodiment, the transmission mechanism 1 can also be composed of two screw rods and a movable plate. The two screw rods are controlled by a servo motor to rotate, and a threaded sleeve threadedly connected to the two screw rods is provided at the bottom of the movable plate, so that when the screw rod rotates, it can drive the movable plate to move back and forth, and the top ends of the two screw rods are connected to the outer wall of the support frame through a fixing part. The fixing part is composed of a circular ring and a fixed rod. The bearing connection is performed through the outside of the screw rod and the inside of the circular ring to complete the work of fixing the position of the screw rod, and the fixed rod is fixed to the inner wall of the support rod by bolts.

[0036] according to Figure 3-5 As shown, two extrusion mechanisms 2 are symmetrically arranged at the top of the conveying mechanism 1, and the extrusion mechanism 2 includes:

[0037] The extrusion block 21 is arranged in a rectangular structure, and the extrusion block 21 is located on the outer side of the conveyor belt of the conveyor mechanism 1 at one side of the central axis of the conveyor mechanism 1;

[0038] The top of the connecting column 22 is integrally installed with the bottom of the extrusion block 21, and the bottom of the connecting column 22 is arranged inside the fixed column 23. The interior of the fixed column 23 is hollow. A compression spring 24 is arranged inside the fixed column 23. The top of the compression spring 24 is connected to the bottom of the connecting column 22. The original length of the compression spring 24 is less than the height of the fixed column 23.

[0039] The driving mechanism 3 comprises:

[0040] The driving gear 33 and the driven gear 34 are bearing-connected to the support frame on the transmission mechanism 1. The driving gear 33 is coaxially connected to a cam 32 on the outside, and the top of the cam 32 is coaxially connected to a driving motor 31. The top of the driven gear 34 is connected to a fixing mechanism 4.

[0041] The cam 32 is arranged below the extrusion block 21, the driving gear 33 and the driven gear 34 are meshed with each other, and the cam 32 and the fixing mechanism 4 are arranged at 90 degrees;

[0042] Specifically, when the driving motor 31 controls the cam 32 to rotate, the cam will rotate clockwise and slowly separate from the bottom of the extrusion block 21. At this time, the compression spring 24 under the connecting column 22 at the bottom of the extrusion block 21 will shrink and reset, thereby causing the entire extrusion block 21 to move downward.

[0043] In the present application, the 90° setting between the cam 32 and the fixing mechanism 4 allows the cam 32 to rotate to the bottom. Due to the mutual meshing of the driving gear 33 and the driven gear 34, the driving gear 33 drives the cam 32 to rotate clockwise, and the driven gear 34 can cause the fixing mechanism 4 to rotate counterclockwise. At this time, the fixing mechanism 4 can be just above the top of the transmission mechanism 1. With the extrusion of the extrusion block 21 on the fixing mechanism 4, the effect of controlling the bottom of the fixing mechanism 4 to contact and fix with the top of the mechanical parts can be achieved.

[0044] according to Figure 3-6 As shown, the fixing mechanism 4 is arranged in a "U"-shaped structure, and the fixing mechanism 4 includes:

[0045] The connecting rod 41 is composed of a rectangular rod and a circular ring, the circular ring is connected to the outside of the intermediate shaft of the driven gear 34, the middle of the connecting rod 41 is connected to an intermediate plate 42 through a sliding mechanism, and the bottom of the intermediate plate 42 is evenly distributed with positioning plates 43 for positioning mechanical parts;

[0046] The sliding mechanism includes a reserved groove 44 provided on the connecting rod 41 and a pressing spring 45 provided inside the reserved groove 44. The top end of the pressing spring 45 is fixedly connected to the sliders on both sides of the middle plate 42.

[0047] Specifically, when the driven gear 34 rotates, it will first drive the connecting rod 41 to rotate until the cam 32 connected to the driving gear 33 is completely separated from the extrusion block 21. At this time, the connecting rod 41 is in a vertical state, and the middle plate 42 at this time also drives the positioning plate 43 at its bottom to work vertically downward. Since the extrusion block 21 is no longer limited by the cam 32 at this time, it will move downward. In fact, the bottom of the extrusion block 21 will push the middle plate 42 to work downward, so that the sliders on both sides of the middle plate 42 squeeze the extrusion spring 45 in the reserved groove 44 to descend, so that the positioning plate 43 will also descend and contact and squeeze with the components to achieve the positioning effect.

[0048] In the present application, after one side of the mechanical component is extruded, rotational displacement work is required. At this time, it is only necessary to control the drive motor 31 to rotate in the opposite direction, and the rotation angle of the drive motor 31 only needs to be rotated slightly. It is only necessary to make the driven gear 34 drive the entire fixing mechanism 4 to offset the position directly above the transmission mechanism 1, which will not affect the normal rotation work of the mechanical components. Therefore, the rotation work of the mechanical components will not be affected by the fixing mechanism 4.

[0049] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
