DETAILED DESCRIPTION

[0043] 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.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Reference Figure 1-Figure 7 The present invention provides an iron accessory positioning turning device, comprising:

[0046] A fixed platform 1 and a mobile platform 2 are distributed along the same horizontal height;

[0047] The first turning plate 3 is rotatably connected to the fixed platform 1, and one side is movably matched with the first claw group 5. The other side of the first turning plate 3 is provided with a positioning assembly, which includes a transport part and a plurality of positioning plates 7. The first turning plate 3 is provided with a control member, and the control end of the control member is connected to the positioning plate 7. The plurality of positioning plates 7 are matched with the center of the first turning plate 3 to define a turning channel 8, and the transport part can transport the blank along the direction of the turning channel 8;

[0048] The second wheel plate 4 is rotatably connected to the moving platform 2, and a second wheel claw group 6 is movably matched on a side close to the first wheel plate 3;

[0049] A first driving assembly, connected to the mobile platform 2, and used to drive the mobile platform 2 to move in at least four directions;

[0050] The tool disc 9 is arranged on one side of the fixed platform 1 and is connected to the second driving assembly. The tool disc 9 can move between the first turning disc 3 and the second turning disc 4 to turn the blank on the first turning jaw group 5 or the second turning jaw group 6.

[0051] The present invention fixes the blank by the first claw group 5 on the first disc 3. When the turning operation of the tool disc 9 on the first disc 3 is completed, the second claw group 6 on the second disc 4 can be used to take out the blank. Then the second drive assembly drives the tool disc 9 to move with the second disc 4 and continue turning on the second disc 4. Not only can the unturned area covered by the first disc 3 be turned, but the whole process does not require personnel to convert the blank. It can be completed through the cooperation of the first drive assembly and the second drive assembly, which effectively reduces the work efficiency of positioning and turning of iron accessories.

[0052] In addition, the present patent also provides a positioning assembly for the first chuck on the fixed table 1, and controls the positioning plate 7 through the control part so that several positioning plates 7 can enclose a turning channel 8, and the turning channel 8 is located at the center of the first turning plate 3, and the transport part transports the blank along the turning channel 8, so that the subsequent repeated turning of the blank can ensure the precise positioning of the first turning position, thereby improving the turning effect of batch blank processing, and the second drive assembly drives the second turning plate 4 to move, so that the second claw group 6 on the second turning plate 4 can directly correspond to the center of the first turning plate 3, that is, the turning channel 8 when grabbing the blank.

[0053] It can be understood that the blank proposed in the present technical solution is a common iron galvanized or iron copper-plated core column 37. The longer core column 37 structure can be directly transported through the transportation part. During the turning process of the turning tool disc 9, after completing the turning of a single iron accessory, the core column 37 in the corresponding area is cut by the cutting tool, and the second claw group 6 can grip the blank during cutting. After the turning operation on the second turning disc 4 is completed, the second drive assembly moves the second claw group 6 to transport the turned iron accessory out of the turning room.

[0054] In the present technical solution, the first jaw group 5 and the second jaw group 6 are common three-jaw centripetal structures. Correspondingly, the centers of the first chuck and the second chuck are provided with through holes penetrating both sides, and the turning channel 8 runs through the through holes of the first chuck and the second chuck.

[0055] Furthermore, a positioning ring 10 is connected to the side of the first disc 3 away from the first claw group 5 through a bearing 39, and a plurality of positioning plates 7 are arranged at equal intervals circumferentially on the inner ring side of the positioning ring 10. The positioning plates 7 are arc-shaped structures, and the recessed parts of the plurality of positioning plates 7 face the axis of the positioning ring 10 to enclose a turning channel 8. A through hole connected to the turning channel 8 is opened in the center of the first disc 3.

[0056] By setting a positioning ring 10 that is connected to the first disc 3, the positioning plates 7 are evenly spaced on the inner ring side of the positioning ring 10, and the arc-shaped recess of the positioning plate 7 is utilized to enclose a turning channel 8 with a circular cross-section, and the turning channel 8 is directly connected to the through hole in the middle of the first disc 3.

[0057] In one embodiment of the present invention, the positioning plate 7 can be tilted toward the axis of the positioning ring 10 along the forward direction of the turning channel 8, thereby forming a conical turning channel 8 with a large port on one side close to the transportation part, which is beneficial for the transportation part to directly pass the core column 37 structure of the blank into the turning channel 8, thereby improving the positioning effect and accelerating the efficiency of the turning operation.

[0058] Furthermore, the control element includes:

[0059] A plurality of calibration cylinders 11 are fixedly connected to the inner ring side of the positioning ring 10 at equal intervals along the circumferential direction and are connected to the positioning plates 7 one by one. The piston ends of the calibration cylinders 11 face the axis of the positioning ring 10.

[0060] The pressure plate 12 has two ends fixedly connected to the piston end of the calibration cylinder 11 and the positioning plate 7 respectively. The pressure plate 12 is used to obtain the pressure signal of the positioning plate 7.

[0061] In the present technical solution, the pressure plate 12 is driven by the calibration cylinder 11 to push the positioning plate 7, and the positioning plate 7 contacts the side wall of the blank to feedback the pressure signal. A pressure sensor (not shown in the figure) is arranged in the pressure plate 12 to obtain the pressure signal formed between the positioning plate 7 and the blank, thereby improving the positioning accuracy of the blank.

[0062] Specifically, when the blank is conveyed along the turning channel 8, the positioning plate 7 is moved by the calibration cylinder 11. When the positioning plate 7 is initially enclosed to form the turning channel 8, due to the different structural dimensions of the blank or the error in the encoding of the moving stroke of the calibration cylinder 11, the turning channel 8 can support the blank, but in fact there are still different gaps between the positioning plates 7 and the blank, that is, the blank cannot be accurately and effectively positioned and supported. Therefore, the end of the blank is clamped based on the above-mentioned three-jaw centripetal first turning jaw group 5 structure. At this time, the pressure signal obtained on the pressure plate 12 corresponds to the gap between the positioning plate 7 and the blank. When the pressure value is greater than the set value of the calibration cylinder 11, the positioning plate 7 is moved by the calibration cylinder 11 to reduce the contact pressure between the positioning plate 7 and the blank. When the pressure value is less than the set value of the calibration cylinder 11 or is zero, the positioning plate 7 is moved by the calibration cylinder 11 to increase the contact pressure with the blank, thereby achieving accurate positioning of the blank.

[0063] Since the blank needs to be turned repeatedly, the blank will be offset from the original position when the first jaw group 5 is released. Therefore, by calibrating and positioning the position when the blank is processed for the first time, the accuracy of the core column 37 continuously transported by the transportation part can be guaranteed during subsequent repeated turning, thereby improving the processing effect when turning and preparing a number of iron accessories.

[0064] The pressure signal is received by an external signal transceiver, and the movement stroke of the piston end of the calibration cylinder 11 is obtained through processor calculation. The encoding program adopts the common ADC calibration system for calculation. The calibration cylinder 11 controls the movement of the positioning plate 7 according to the calculated movement stroke to realize the calibration of the positioning of the turning channel 8.

[0065] Furthermore, the Ministry of Transport includes:

[0066] The conveying platform 13 is arranged on the fixed platform 1. A lifting cylinder 14 is fixedly connected to the top surface of the fixed platform 1. The piston end of the lifting cylinder 14 is fixedly connected to the conveying platform 13. A conveying groove is provided on the top surface of the conveying platform 13. The conveying groove has an opening on one side facing the turning channel 8.

[0067] The conveying wheel 15 is connected to the conveying platform 13, and one side of the conveying wheel 15 extends into the conveying groove and is connected to the blank, so that the blank moves along the opening direction.

[0068] The conveying platform 13 is controlled to be at the same horizontal height as the first turning plate 3 by the lifting cylinder 14, and the conveying wheel 15 is rotated and slidably contacted with the blank, so that the blank is conveyed along the opening direction. Since the opening on the conveying trough faces the turning channel 8, the blank is transported along the turning channel 8.

[0069] The above-mentioned blank is a core column 37 structure, so the length of the blank corresponds to the length of the conveying trough. Combined with this patent, the first turning plate 3 and the second turning plate 4 cooperate to achieve cyclic turning preparation of the blank, which effectively improves the efficiency of turning iron accessories.

[0070] Furthermore, the conveying wheel 15 is a polyurethane rubber-coated wheel, and at least two conveying wheels 15 are arranged opposite to each other on both sides of the conveying groove, and the two opposite conveying wheels 15 respectively roll against the blank.

[0071] Polyurethane rubber-coated wheels are used to increase the contact friction between the conveying wheel 15 and the blank. At least two conveying wheels 15 arranged opposite to each other are used to roll against the blank on both sides of the blank, thereby increasing the contact friction and improving the conveying effect on the blank.

[0072] Furthermore, it also includes:

[0073] The mounting plate 16 is fixedly connected to the side wall of the conveying platform 13. A rotating motor 17 is fixedly connected to the outer wall of the mounting plate 16.

[0075] The screw 18 is rotated by rotating the motor 17, and the screw 18 is threadedly sleeved with a sleeve 20, and the conveying seat 19 and the groove limit slide groove make the conveying seat 19 slide along the groove direction, drive the conveying wheel 15 to move toward the conveying groove, and the conveying wheel 15 is abutted against the blank, and then the driving motor 21 drives the conveying wheel 15 to rotate, so as to realize the axial conveying of the blank along the conveying groove.

[0076] Furthermore, the first driving component includes:

[0077] A first linear slide rail 22 and a second linear slide rail 23, wherein the slider end of the first linear slide rail 22 is fixedly connected to the second linear slide rail 23, and the slider end of the second linear slide rail 23 is fixedly connected to the bottom surface of the moving platform 2;

[0078] The axis direction of the first linear guide rail 22 is perpendicular to the turning channel 8 , and the axis direction of the second linear guide rail 23 is coaxially distributed with the turning channel 8 .

[0079] The first linear slide 22 and the second linear slide 23 cooperate to drive the movable table 2, so that the movable table 2 moves at the same horizontal height as the fixed table 1, so that the second turning plate 4 can connect the blank from the first turning plate 3, and the turned iron accessories can be transported out of the turning room, thereby improving the turning operation efficiency.

[0080] Further, the second driving assembly includes:

[0081] The third linear slide rail 24 and the fourth linear slide rail 25, the slider end of the third linear slide rail 24 is fixedly connected to the fourth linear slide rail 25, and the slider end of the fourth linear slide rail 25 is connected to the turning tool disc 9, wherein the third linear slide rail 24 is installed on one side of the fixed table 1 in the vertical direction, the fourth linear slide rail 25 is arranged parallel to the turning channel 8, and the stroke of the fourth linear slide rail 25 is not less than the distance from the first turning disc 3 to the far end of the second linear slide rail 23.

[0082] Similarly, the third linear slide rail 24 and the fourth linear slide rail 25 can improve the movement freedom of the tool disc 9, so that the tool disc 9 can be switched to the first turning disc 3 or the second turning disc 4 for turning work, and the stroke of the fourth linear slide rail 25 is not less than the distance from the first turning disc 3 to the far end of the second linear slide rail 23, which can ensure that the turning range of the tool disc 9 effectively covers the second claw group 6 on the second turning disc 4.

[0083] Furthermore, it also includes:

[0084] The first telescopic cylinder 26 is fixedly connected to the slider end of the fourth linear slide rail 25, and the piston end of the first telescopic cylinder 26 is fixedly connected to the rotary cylinder 27.

The plurality of tool seats 29 are used to fix different tooling tools.

[0085] Under the action of the first telescopic cylinder 26, the rotary cylinder 27 moves in the direction away from the fourth linear slide rail 25 and close to the fixed platform 1, and then the tool disc 9 is controlled to rotate by the rotary cylinder 27, so that one of the several turning tools arranged circumferentially on the tool disc 9 corresponds to the grasping end of the first claw group 5 or the second claw group 6, and the different turning tools are used to achieve the turning effect on the different turning requirements of the iron accessories. The corresponding tool seat 29 is controlled by the second telescopic cylinder 28 to move in the direction away from the tool disc 9, and the corresponding tool is moved to the turning position to prevent the remaining tool seats 29 from hindering the rotation of the first claw group 5 or the second claw group 6.

[0086] Furthermore, it also includes:

[0087] The adapter ring 30 is fixedly connected to the top surface of the fixed platform 1 and the movable platform 2. The inner ring side of the adapter ring 30 is limitedly connected with a driven pulley 31. The fixed platform 1 and the movable platform 2 are respectively connected with driving pulleys 32. The adjacent driving pulleys 32 are transmission-connected with the driven pulleys 31. The first disc 3 and the second disc 4 are respectively fixedly connected to the mutually adjacent sides of the two driven pulleys 31 on the fixed platform 1 and the movable platform 2.

[0088] By fixing the stepper motor 33 on the fixed table 1 and the movable table 2, the output shaft of the stepper motor 33 is fixedly connected to the axis of the driving pulley 32, and a transmission belt is sleeved between the driving pulley 32 and the driven pulley 31, a transmission hole is opened on the adapter ring 30 accordingly to ensure the transmission connection of the transmission belt, so that the driven pulley 31 can rotate on the inner ring side of the adapter ring 30, and the first disc 3 and the second disc 4 are driven to rotate by the driven pulley 31 to realize the turning operation of the grasped blank.

[0089] In one embodiment of the present invention, one side of the driven pulley 31 on the fixed platform 1 is fixedly connected to the first disc 3, and the other side is connected to the positioning ring 10 through a bearing 39, while one side of the driven pulley 31 located on the movable platform 2 is fixedly connected to the second disc 4, and the other side is fixedly connected to a fixed seat 34, a multi-stage telescopic rod 35 is fixedly connected to the fixed seat 34, and a top 36 is fixedly connected to the telescopic end of the multi-stage telescopic rod 35. When turning is performed on the first disc 3, the top 36 is passed through the second disc 4 and extended to abut against the blank, thereby improving the stability of the turning operation, and when turning is performed on the second disc 4, the top 36 is retracted to ensure that the second claw group 6 effectively grasps the blank.

[0090] The working principle of the iron accessory positioning turning device of the present invention is:

[0091] Taking the turning of the pagoda-shaped terminal 38 as an example, an iron galvanized core column 37 is used as a blank, which is placed in the conveying trough, and the screw 18 is rotated by the rotating motor 17. The screw 18 drives the conveying seat 19 to move the conveying wheel 15. When the conveying wheels 15 on both sides of the conveying trough are against the blank, the driving motor 21 rotates the conveying wheel 15 to transport the blank along the direction of the first turning plate 3, and the calibration cylinder 11 is used to move the positioning plate 7 to form a turning channel 8. The turning channel 8 is used for guiding and positioning, and the end of the blank is moved to the first claw group 5 and extended to a length greater than the pagoda-shaped terminal 38. The end of the blank is gripped by the first claw group 5 to avoid the pressure effect of the gravity of the blank on the positioning plate 7. Then, the calibration cylinder 11 continues to move the positioning plate 7, and the pressure plate 12 is used to obtain the pressure signal, so that the contact pressure of each positioning plate 7 and the blank is the same, so as to achieve accurate positioning of the turning channel 8 and ensure the accuracy of subsequent continuous conveying of the blank.

[0092] The tool disc 9 is driven to move to the position of the first claw group 5 by the third linear slide rail 24 and the fourth linear slide rail 25, and then the first telescopic cylinder 26 and the second telescopic cylinder 28 cooperate to move the tool seat 29, and the tool seat 29 with the inclined tool fixed is moved to the position of the pagoda-shaped terminal 38, and the driven pulley 31 is rotated by the active pulley 32 to rotate the first turning disc 3 for turning. During the turning process, the second telescopic cylinder 28 and the third linear slide rail 24 and the fourth linear slide rail 25 cooperate to control the position of the turning pagoda. During the process, the top 36 on the second turning disc 4 extends out and abuts against the blank.

[0093] After turning out the pagoda structure, the turning tool is changed by rotating the turning tool disc 9 through the rotating cylinder 27, and the top 36 is retracted. The second turning disc 4 is moved by the first linear slide 22 and the second linear slide 23, and the pagoda area of ​​the blank is fixed by the second claw group 6. Then the turning tool disc 9 is switched to the cutting tool to cut the iron accessory and the core column 37, and the second turning disc 4 is moved in the direction away from the first turning disc 3. At the same time, the turning tool disc 9 moves with the second turning disc 4, and the turning tool is switched again to perform external threads on the remaining areas of the iron accessory and turn the hexagonal bolt head. After the turning is completed, the second turning disc 4 directly transports the iron accessory in the direction away from the fixed platform 1 to achieve the turning processing of the iron accessory.

[0094] Then the conveying wheel 15 repeats the above steps to extend the core column 37 of the blank out of the first claw group 5.
