Description

Technical Field

[0001] The invention relates to the technical field of automatic processing of nuts, and in particular to a multi-process composite automatic processing system for nuts. Background Art

[0002] The forming process of the nut is to cut the heated steel bar into small pieces, and then make it into a hexagonal shape through the extrusion of the mold, and then use a punch to drill a round hole in the middle, and after cooling, use a tap to carve a thread in the round hole; the nut blank needs to be fixed during the tapping process to prevent the nut from shaking during the tapping process; in order to facilitate the tapping of the round hole in the middle of the nut blank, the nut is usually fixed by fixing the outer six sides of the nut, and then the punch will have errors during long-term use. The round hole drilled by the punch in the middle of the nut blank and the inscribed circle of the hexagon will be eccentric due to the error, and the tap is often set to be coaxial with the fixture, which will cause the internal thread depth of the nut to be inconsistent when the tap is tapped, which will greatly affect the quality of the nut and reduce the tightening effect during subsequent use.

DETAILED DESCRIPTION

[0024] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 6 The present invention provides a technical solution: a multi-process composite nut automated processing system, comprising a processing table 1, a partition baffle 2, a tap 3 and a clamping and positioning mechanism 4; the partition baffle 2 is fixedly connected to the top of the processing table 1 and divides the processing table 1 into a clamping area and an execution area; the tap 3 is located in the execution area and can self-drive to execute the tapping command; the clamping and positioning mechanism 4 is located in the clamping area and can position the nut through the inner hole of the nut while clamping the calibrated nut.

[0026] The staff places the nut into the clamping area on the top of the processing table 1, and the nut is located between the clamping positioning mechanism 4 and the partition baffle 2; then the clamping positioning mechanism 4 can start to work, and the clamping positioning mechanism 4 will position the nut through the circular hole in the middle of the nut blank, so that the circular hole in the middle of the nut and the tap 3 are in a coaxial state, and the nut is clamped at the same time; after the nut position adjustment is completed, the tap 3 can perform tapping work, and after the tapping work is completed, the staff will remove the processed nut from the processing table 1.

[0027] Specifically, Figure 1-Figure 3As shown, the clamping and positioning mechanism 4 includes a clamping disk 5, a slide bar 6, a correction rod 7 and a driving part; the clamping disk 5 is slidably connected to the processing table 1 in the horizontal direction and is coaxially arranged with the tap 3; the slide bar 6 is arranged to be a plurality of the clamping disk 5 distributed in a circular array, and all are elastically slidably connected to the clamping disk 5 in the radial direction; the correction rod 7 is arranged to be a plurality of the same number as the slide bar 6, and all are elastically slidably connected to the slide bar 6 in the horizontal direction; the correction rod 7 can be inserted into the inner hole of the nut and can adjust the position of the nut so that the inner hole of the nut is coaxial with the clamping disk 5; the driving part is arranged on the side of the clamping disk 5, and the driving part can drive the clamping disk 5 to clamp the nut and drive the correction rod 7 to correct the position of the nut; the driving part includes a slider 8, a first traction rope 9, a detection rod 10, a limit block 1 1, a second traction rope 12 and a linear drive mechanism; the slider 8 is elastically slidably connected to the clamping disk 5 in the axial direction; the first traction rope 9 is set to be a plurality of the same number as the slide bar 6, one end of which is fixedly connected to the slider 8, and the other end passes through the side wall of the clamping disk 5 and is fixedly installed on the top of the slide bar 6; the detection rod 10 is slidably connected to the clamping disk 5 in the axial direction, and one end is located on the same side of the correction rod 7; the limit block 11 is elastically slidably connected to the clamping disk 5 in the radial direction and can limit the slider 8; the second traction rope 12 is used to connect the detection rod 10 and the limit block 11, and when the detection rod 10 moves to the left, the limit block 11 can be driven by the second traction rope 12 to move outward to cancel the limit on the slider 8; the linear drive mechanism is used to drive the slider 8 to slide in the horizontal direction.

[0028] After the nut to be tapped is placed on the top of the processing table 1, the linear drive mechanism drives the slider 8 to move horizontally to the right; Figure 2 As shown, since the slider 8 is limited by the limit block 11 at this time, the slider 8 will drive the clamping plate 5 to move to the right synchronously through the limit block 11; the detection rod 10 on the clamping plate 5 will first move to contact the side wall of the nut. When the clamping plate 5 continues to move to the right, the detection rod 10 will move to the left relative to the clamping plate 5, and the detection rod 10 will drive the limit block 11 to move outward through the second traction rope 12. When the clamping plate 5 moves to fit the nut, the limit block 11 moves to a position where it is out of contact with the slider 8 to cancel the limit on the slider 8; then the linear drive mechanism will drive the slider 8 to move to the right relative to the clamping plate 5, and the slider 8 will pass through the first traction rope The rope 9 drives the slide bar 6 to move outward, and multiple slide bars 6 will move outward synchronously. The slide bar 6 will drive the correction rod 7 to move synchronously. After multiple correction rods 7 move to contact the circumferential side wall in the middle of the nut, the correction rod 7 will correct the position of the nut through the circular hole in the middle of the nut. At this time, the circular hole in the middle of the nut is coaxial with the clamping disk 5 and the tap 3; at this time, the position adjustment of the nut is completed, and it is clamped by the clamping disk 5 and the partition baffle 2 at the same time; then the tap 3 can start working, and during the tapping process of the tap 3, the left end of the tap 3 can push the correction rod 7 to slide inwardly of the slide bar 6, so as to avoid the correction rod 7 hindering the work of the tap 3.

[0029] Specifically, Figure 2 As shown, the linear drive mechanism includes a first cylinder 13 installed on the top of the processing table 1, and the output end of the first cylinder 13 is fixedly connected to the slider 8; the first cylinder 13 can drive the slider 8 to move in the horizontal direction.

[0030] Specifically, Figure 5 As shown, a second cylinder 18 is installed on the top of the processing table 1, and a slide 19 is fixedly connected to the output end of the second cylinder 18. A motor 20 for driving the tap 3 to rotate is fixedly installed on the slide 19.

[0031] The second cylinder 18 can drive the slide 19, the click 20 and the tap to move in the horizontal direction, and the motor 20 can drive the tap 3 to rotate to complete the tapping work on the inner hole of the nut.

[0032] Specifically, Figure 5 and Figure 6 As shown, two fixed blocks 21 located in the clamping area are installed on the partition baffle 2, and the first cylinder body 22 is fixedly installed on the two fixed blocks 21 and the top of the processing table 1, and the first piston 23 is slidably installed in the first cylinder body 22; the outer ends of the first pistons 23 are fixedly connected to the clamping baffles 24; the three clamping baffles 24 are distributed in a circular array about the axis of the clamping disk 5; the second cylinder body 25 is installed on the top of the processing table 1, and the first cylinder body 22 is connected to the second cylinder body 25 through a hose; the second piston 26 is elastically slidably connected in the second cylinder body 25, and the push plate 27 is elastically slidably installed on the second piston 26, and the push plate 27 is located in the execution area and on the side of the slide 19.

[0033] like Figure 6As shown, in this embodiment, the staff needs to place the nut to be processed on the clamping baffle 24 below. It should be noted that the two clamping baffles 24 on the front and rear sides do not contact the side walls of the nut in the initial state, which can facilitate the removal and placement of the nut; when the second cylinder 18 drives the slide 19 to move to the left, the slide 19 will drive the push plate 27 to move to the left after moving to contact with the push plate 27, and the push plate 27 will drive the second piston 26 to move to the left through elastic parts such as springs to squeeze the hydraulic oil in the second cylinder body 25. The hydraulic oil in the second cylinder body 25 will enter the first cylinder body 22 through a hose. Under the pressure of the hydraulic oil, the first piston 23 will drive the clamping baffle 24 to move to the side close to the nut until the clamping baffle 24 moves to fit the nut; it should be noted that when the tap 3 moves to the left to prepare for tapping, the clamping and positioning mechanism has adjusted and clamped the position of the nut; therefore , if the circular hole in the middle of the nut is in an eccentric state with its hexagonal inscribed circle, the moving distances of the three clamping baffles 24 will be different, and each clamping baffle 24 will stop moving after moving to fit with the nut. Due to the incompressibility of the hydraulic oil, the three clamping baffles 24 move to fit with the nut, and the second piston 26 does not retreat to the right. The three clamping baffles 24 can cooperate with the clamping disk 5 and the partition baffle 2 to achieve complete positioning of the nut, which can better ensure that the nut will not shake during the tapping process, ensure the tapping quality of the nut, and protect the tap 3; after completing the tapping work, after the tap 3 moves back to the initial position to the right, the force applied to the second piston 26 disappears, and at this time, the second piston 26 can move back to the initial position to the right under the action of the spring force, and then the clamping force of the three clamping baffles 24 on the nut disappears, and the staff can easily remove the nut after processing.

[0034] Specifically, Figure 6 As shown, a mounting frame 28 is fixedly connected to the partition baffle 2, and a belt conveyor assembly 29 is installed inside the mounting frame 28. The belt conveyor assembly 29 is arranged in an inclined shape near one end of the partition baffle 2.

[0035] The nuts to be processed can be placed on the top of the belt conveyor assembly 29, and the belt conveyor assembly 29 will convey the nuts to the left. After moving to the inclined end of the belt conveyor assembly 29, the nuts will automatically fall downward. Under the action of the mounting frame 28, the nuts will fall vertically to the top of the clamping baffle 24 below; automatic loading of nuts can be realized, which can greatly reduce the workload of staff.

[0036] Specifically, Figure 2-Figure 4As shown, a fixing rod 14 fixedly connected to the clamping plate 5 is provided on the side of the slider 8, and a wedge-shaped clamping block 15 is fixedly connected to the fixing rod 14; an inserting block 16 is slidably connected to the inner side of the slider 8 in the vertical direction, and the wedge-shaped clamping block 15 can limit the inserting block 16; a wedge-shaped push rod 17 capable of driving the inserting block 16 to disengage from the wedge-shaped clamping block 15 is fixedly connected to the processing table 1.

[0037] When the clamping plate 5 moves to fit the nut, the slide block 8 starts to move rightward relative to the clamping plate 5, and the slide block 8 will drive the plug block 16 to move rightward synchronously. The plug block 16 will move upward when it contacts the wedge-shaped block 15, and will move downward under the action of gravity or spring force after it loses contact with the wedge-shaped block 15. After the plug block 16 moves to the right, the wedge-shaped block 15 can limit the plug block 16; after completing the tapping work, when the tap 3 moves to the right, the extrusion force of the tap 3 on the correction rod 7 disappears, and the correction rod 7 extends out from the slide bar 6 to support the nut, and the three clamping baffles 24 cancel the limit on the nut. Then, when the first cylinder 13 drives the slide block 8 to move leftward, since the plug block 16 is stuck by the wedge-shaped block 15, the slide block 8 can only drive the clamping plate 5 to move leftward synchronously through the fixing rod 14. Since the nut is hung on the correction rod 7, the clamping plate 5 will drive the nut to move left synchronously through the correction rod 7; Figure 4 As shown, until the insert block 16 moves to the left and contacts with the wedge-shaped push rod 17, the wedge-shaped push rod 17 will drive the insert block 16 to move upward. After the insert block 16 is staggered with the wedge-shaped block 15, the clamping plate 5 will move to the right relative to the slider 8 under the elastic force of the spring, and the slider 8 will drive the limit block 11 to move synchronously. After moving to the right side of the slider 8, the limit block 11 will move toward the inner side of the clamping plate 5 under the elastic force of the spring. The limit block 11 will drive the detection rod 10 to move to the right through the second traction rope 12, and the detection rod 10 will push the processed nut to the right, thereby realizing automatic unloading of the nut, which can greatly improve the efficiency of nut tapping.
