Description

Technical Field

[0001] The present invention belongs to the field of hexagon nut processing, and particularly relates to an automatic processing device and processing method for hexagon nuts. Background Art

[0002] Hexagon nuts are common fasteners and are widely used in fields such as mechanical assembly and construction engineering. The main processing steps of hexagon nuts include raw material cutting, extrusion molding, turning, etc.

[0003] Some heavy machinery, mining equipment, or wind power generation equipment usually require the use of larger-sized hexagon nuts to meet the requirements of high-strength connection and bearing large loads.

[0004] Currently, when processing larger hexagon nuts, after the conveying device conveys the hexagon nuts to the designated position, in order to ensure the stability of the hexagon nuts during processing, generally, a clamping robot with visual recognition is required to pick up the hexagon nuts from the conveying device, then place them on the designated processing table, and then fix the hexagon nuts for turning processing. After the processing is completed, they are put back on the conveying device. This processing method requires the use of a clamping robot for loading and unloading each hexagon nut, and the efficiency needs to be improved. Moreover, since the hexagon nut has six outer sides when placed horizontally, usually only two outer side walls of the hexagon nut are fixed during processing, which is prone to deviation and the stability is not high. At the same time, clamping robots with vision systems and high-precision clamping functions are usually expensive, and the subsequent maintenance cost is high, and the equipment usage cost is large, which is not conducive to popularization and use.

[0021] Compared with the prior art, the hexagonal nut automatic processing device and processing method provided by the embodiment of the present invention have the following beneficial effects:

[0022] 1. In the present invention, by cooperating with the conveying mechanism 1 and the conveying mechanism 2 and the pressure detector on the baffle bar, not only can the hexagonal bolts be accurately conveyed to the specified position, but also the two conveyor belts 2 symmetrically distributed on the conveying platform can provide sufficient space for the processing of the hexagonal nuts. By cooperating with the fixing mechanism and the turning mechanism, the hexagonal nuts can be fixed and processed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following is a further detailed description of this application Figure 1-6 in conjunction with the appended

[0034] Please refer to Figure 1 , the drawings and Figure 3, An automatic processing device for hexagonal nuts, including a conveying table 1. Conveying mechanisms one 2 are provided at both the front and rear ends of the conveying table 1, and a conveying mechanism two 3 is provided in the middle of the conveying table 1. An installation frame 4 is also provided in the middle of the conveying table 1. The installation frame 4 includes a horizontal plate 41, and four columns 42 are fixedly arranged at the bottom of the horizontal plate 41. A turning mechanism 5 is arranged on the installation frame 4. The turning mechanism 5 includes an electric push rod one 51 fixedly arranged on the upper part of the horizontal plate 41. The telescopic end of the electric push rod one 51 is fixedly connected to a motor three. The output shaft of the motor three is connected to a rotating shaft, and a tapping head 52 and a drilling head 53 are fixedly connected to the rotating shaft in sequence from top to bottom. And a fixing mechanism 6 for positioning the hexagonal nut is also arranged on the installation frame 4. The hexagonal nut is conveyed to the lower part of the turning mechanism 5 through the cooperation of the conveying mechanism one 2 and the conveying mechanism two 3. Then, the hexagonal nut is directly fixed on the conveying table 1 through the fixing mechanism 6, and then processed by the turning mechanism 5.

[0035] Refer to Figure 1 , Figure 5 , Figure 6 , A conveying channel is opened on the conveying table 1. The conveying mechanism one 2 includes two conveying rollers one 21 rotatably arranged on the left and right inner walls of the conveying channel. A conveyor belt one 22 is sleeved between the two conveying rollers one 21. One end of any one of the conveying rollers one 21 is connected to a motor one fixedly arranged on the right side wall of the conveying table 1. The conveying mechanism two 3 includes two conveying rollers two 31 rotatably arranged between the left and right inner walls in the middle of the conveying channel. Two conveyor belts two 32 are sleeved between the two conveying rollers two 31. The two conveyor belts two 32 are symmetrically distributed left and right on the conveying rollers two 31, and an activity opening 33 is formed between the two conveyor belts two 32. One end of any one of the conveying rollers two 31 is connected to a motor two fixedly arranged on the right side wall of the conveying table 1. A support plate 7 is fixedly arranged on both the left and right inner walls in the middle of the conveying channel, which can improve the support effect of the conveyor belt. The upper part of the support plate 7 is movably attached to the bottom of the upper horizontal section of the conveyor belt two 32. A guiding strip is fixedly arranged on both the left and right inner walls at the front end of the conveying channel. The upper end surface of the conveyor belt one 22 at the front end is higher than the upper end surface of the conveyor belt two 32, and the upper end surface of the conveyor belt one 22 at the rear section is lower than the upper end surface of the conveyor belt two 32, so that the hexagonal nut can move between the conveyor belt one 22 and the conveyor belt two 32 more smoothly and easily.

[0036] In order to facilitate the processing of hexagon nuts on the conveying table 1, the first conveyor belt 22 drives the rotation of the first conveying roller 21 through the first motor to drive the hexagon nuts to move, and the second conveyor belt 32 drives the rotation of the second conveying roller 31 through the second motor to drive the hexagon nuts to move. When the hexagon nuts move to the middle of the conveying table 1, both ends of the bottom of the hexagon nuts are supported by a second conveyor belt 32. The movable opening 33 formed between the left and right second conveyor belts 32 can provide sufficient space for the processing of the hexagon nuts, facilitating the positioning of the hexagon nuts by the fixing mechanism 6 without hindering the processing of the hexagon nuts when the turning mechanism 5 moves downwards.

[0037] Refer to Figure 1 - Figure 5 , the fixing mechanism 6 includes alignment plates 61 respectively movably arranged on the upper parts of the left and right sides of the conveying table 1. A support assembly 62 is arranged below the middle of the conveying table 1. Driving assemblies 63 for driving the alignment plates 61 and the support assembly 62 to act are commonly arranged on both the mounting frame 4 and the left and right sides of the conveying table 1. A U-shaped bracket 64 is fixedly arranged between the upper parts of the left and right sides of the conveying table 1. Two retaining bars 65 are movably inserted on the bracket 64. A pressure detector is arranged on the front side of the lower end of the retaining bar 65, and two stoppers 66 are fixedly arranged on the front side wall of the horizontal section of the bracket 64.

[0038] In order to facilitate the fixation of the left and right outer side walls of the hexagon nuts to be processed at the middle position of the conveying channel, when the hexagon nuts to be processed in the conveying channel move to the middle position of the conveying channel, the hexagon nuts will abut against the two retaining bars 65. After the pressure detector on the retaining bar 65 detects a pressure signal, the first conveying mechanism 2 and the second conveying mechanism 3 are controlled to stop working through an external controller, and then the left and right alignment plates 61 are driven to move towards the hexagon nuts in the conveying channel through the driving assembly 63, so that the two alignment plates 61 abut against the left and right outer side walls of the hexagon nuts. And when the two alignment plates 61 approach each other, the alignment plates 61 will also align the hexagon nuts to be processed inside the front end of the conveying channel, so that the hexagon nuts inside the front end of the conveying channel can be centered and conveyed on the front first conveyor belt 22.

[0039] Refer to Figure 2 and Figure 6, a sliding plate 67 is slidably arranged on one side of the alignment plate 61 close to the hexagonal nut, and a clamping jaw 68 is rotatably arranged on one side of the alignment plate 61 close to the hexagonal nut. A linkage assembly 69 is arranged between the sliding plate 67 and the clamping jaw 68. A second chute and a receiving groove 8 communicating with the second chute are formed on one side of the alignment plate 61 close to the hexagonal nut. The sliding plate 67 is slidably arranged in the second chute. A third spring is fixedly connected between one end of the sliding plate 67 away from the hexagonal nut and the inner wall of the second chute. The clamping jaw 68 is rotatably arranged in the receiving groove 8. The linkage assembly 69 includes a linkage gear set 691 rotatably arranged in the receiving groove 8 and the second chute. The linkage gear set 691 is composed of two meshing gears. Tooth grooves are formed on the outer wall of one side of the sliding plate 67 close to the linkage gear set 691. A plurality of toothed plates 692 composed of tooth blocks are fixedly arranged in the tooth grooves. The toothed plates 692 are meshed with the adjacent gears on the linkage gear set 691. One end of the clamping jaw 68 is fixedly connected with the corresponding gear on the linkage gear set 691.

[0040] In order to further fix the outer wall of the hexagonal nut, when the left and right alignment plates 61 approach each other under the action of the driving assembly 63 until the alignment plates 61 are attached to the left and right outer walls of the hexagonal nut, the sliding plate 67 of the alignment plate 61 that originally protruded from the second chute will be compressed into the interior of the second chute. The movement of the sliding plate 67 cooperates with the toothed plate 692 on its side wall, which will drive the linkage gear set 691 to act, causing the linkage gear set 691 to drive the clamping jaw 68 to rotate, and finally making the left and right clamping jaws 68 abut against the two front outer walls of the hexagonal nut. At this time, the two rear outer walls of the hexagonal nut will abut against the two stop bars 65, so that the six outer walls of the hexagonal nut are simultaneously limited and fixed, having a good positioning effect on the hexagonal nut in the horizontal direction.

[0041] Refer to Figure 2 - Figure 5 , the support assembly 62 includes a fixed platform 621 arranged below the middle of the conveying table 1. A support column 622 is slidably arranged on the upper part of the fixed platform 621. An activity groove 6221 for the downward movement and processing of the turning mechanism 5 to enter is formed on the upper part of the support column 622. The first support blocks 623 are slidably arranged on the outer walls of the left and right sides at the lower end of the fixed platform 621. The first springs are fixedly arranged on the outer walls of the left and right sides of the fixed platform 621. One end of the first spring away from the fixed platform 621 is fixedly connected with the corresponding first support block 623. The first guide rollers are rotatably arranged on the outer walls of the two sides at the lower end of the support column 622. The inclined slopes are arranged at one end of the two first support blocks 623 close to each other.

[0042] In order to position the upper and lower surfaces of the hexagonal nut to further improve its stability during processing, two first supporting blocks 623 can move closer to each other under the action of their respective driving components 63, so that the two first supporting blocks 623 can simultaneously squeeze the lower end of the supporting column 622 to move the supporting column 622 upward. The guiding roller at the lower end of the supporting column 622 contacts the first supporting block 623, which can reduce the friction when the two are in contact. When the supporting column 622 moves upward, it will contact the hexagonal nut directly above and lift the hexagonal nut to a certain height. Eventually, when the hexagonal nut is separated from the second conveyor belt 32, it will contact the bottom of the two upper stoppers 66. While the lower end of the hexagonal nut is supported by the upper end of the supporting column 622, the upper surface of the hexagonal nut can be limited by the lower end surfaces of the two stoppers 66, so as to support and limit the upper and lower surfaces of the hexagonal nut, and further improve the stability of the hexagonal nut during processing.

[0043] Refer to Figure 2 - Figure 5 , the driving component 63 includes a second electric push rod 631 fixedly arranged on the upper part of the cross plate 41. The telescopic end of the second electric push rod 631 is fixedly connected with a second supporting block 632. A guiding block 421 is fixedly arranged on one side of the column 42 close to the second supporting block 632. Guiding grooves matching the guiding block 421 are formed on the front and rear outer walls of the supporting block. Two pulleys are arranged at the front and rear ends of the bottom of the lower end of the sliding seat 634. Fixed seats 633 are fixedly arranged on the left and right sides of the conveying table 1. A first chute is formed in the fixed seat 633. A sliding seat 634 is slidably arranged in the first chute. A first connecting plate 635 is fixedly connected between the outer wall of the sliding seat 634 corresponding to the conveying table 1. The upper end of the sliding seat 634 is in a slope shape. A second guiding roller is rotatably arranged at the bottom of the lower end of the second supporting block 632. Two guiding rods 636 are fixedly arranged in the first chute. Second springs are sleeved on the surfaces of the two guiding rods 636. A through hole is formed at the bottom of the first chute. A second connecting plate 637 is fixedly arranged at the bottom of the lower end of the sliding seat 634. The second connecting plate 637 is slidably arranged in the through hole. One connecting rod 638 is movably inserted into the lower end of the second connecting plate 637. Two limiting discs 639 are fixedly arranged at one end of the connecting rod 638 close to the corresponding second connecting plate 637. The second connecting plate 637 is movably arranged between the two limiting discs 639.

[0044] In order to drive the alignment plate 61 and the support assembly 62 to act simultaneously through a single driving component 63, when the second electric push rod 631 extends, the second top support block 632 will move downward and abut against the inclined plane of the lower slide 634. At this time, the guide block 421 on the column 42 will be inserted into the guide groove on the second top support block 632. The guide block 421 can guide and support the second top support block 632. The downward movement of the second top support block 632 forces the slide 634 to move towards the conveying table 1. The pulley at the bottom of the slide 634 can reduce the friction between the slide 634 and the first chute, facilitating the movement of the slide 634. Thus, the slide 634 can push the alignment plate 61 to move and abut against the left and right outer walls of the hexagonal nut. At the same time, the jaws 68 on the two alignment plates 61 can abut against the front two outer walls of the hexagonal nut, enabling the six outer walls of the hexagonal nut to be limited simultaneously. And the second connecting plate 637 below the slide 634 moves towards the conveying table 1 synchronously when the slide 634 moves. During the movement, it will come into contact with the limit disk 639 at the right end of the connecting rod 638. Then, the second connecting plate 637 drives the connecting rod 638 to move towards the conveying table 1 together. At the same time, the connecting rod 638 pushes the first top support block 623 to move, enabling the first top support block 623 to drive the support column 622 to move upward, so that the support column 622 can lift the hexagonal nut directly above and make the upper end face of the hexagonal nut abut against the stop block 66, limiting the upper and lower surfaces of the hexagonal nut.

[0045] In addition, the present invention also provides an automatic processing method for hexagonal nuts, which is completed in cooperation with the above-mentioned automatic processing device for hexagonal nuts, including the following steps:

[0046] S1. Feeding: Transport the hexagonal nuts to be processed onto the first conveyor belt 22 at the front end of the conveying table 1. The first conveyor belt 22 drives the hexagonal nuts to move under the cooperation of the first conveyor roller 21 and the first motor.

[0047] S2. Conveying: Convey the hexagonal nuts from the first conveyor belt 22 at the front end of the conveying table 1 to the second conveyor belt 32 in the middle of the conveying table 1. The second conveyor belt 32 drives the hexagonal nuts to move through the cooperation of the second conveyor roller 31 and the second motor until the hexagonal nuts come into contact with the stop bar 65 and reach the specified position.

[0048] S3. Positioning: Fix the hexagonal nuts through the fixing mechanism 6 so that the hexagonal nuts can be fixed at the middle position of the conveying table 1.

[0049] S4. Drilling and tapping: The first electric push rod 51 extends to drive the drill head 53 and the tapping head 52 to move downward. At the same time, the drill head 53 and the tapping head 52 are driven to rotate by the third motor to drill and tap the hexagonal nuts.

[0050] S5. Discharging: The fixing mechanism 6 releases the fixation of the hexagon nut. Meanwhile, the first electric push rod 51 contracts to drive the stop bar 65 to move upward, so that the stop bar 65 no longer limits the rear outer wall of the hexagon nut. At this time, the hexagon nut is completely released from the limit, and is conveyed again through the second conveying mechanism 3 and the first conveying mechanism 2 at the rear end of the conveying table 1, and is transferred to the next process for processing. When the processed hexagon nut is removed, the first electric push rod 51 extends again to reset the stop bar 65 to its original position to wait for the next hexagon nut.

[0051] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
