Bolts are indispensable in daily life and industrial production and manufacturing. Bolts are also known as the rice of industry, indicating the wide application of bolts. The application scope of bolts includes: electronic products, mechanical products, digital products, power equipment, electromechanical machinery products, ships, vehicles, water conservancy projects, and even chemical experiments.

[0003] In the prior art, during the process of bolt installation by an automated bolt processing and assembly device, the processing turntable will periodically stop working, and then the feeding, processing, and discharging processes will be completed one by one through multiple starts and stops, which means that the entire assembly process will also be interrupted accordingly.

[0016] 2. During the rotation of the operation table, through the interaction between the second magnet and the first magnet, the sliding rod is driven to slide inside the movable hole, and at the same time, the reset spring is stretched. When the sliding plate moves towards the fixed seat side, through the elastic recovery of the compression spring, the arc-shaped plate moves downward and approaches the upper end of the fitting, and finally the pressing plate presses on the upper surface of the fitting, thereby further promoting the positioning of the fitting, improving its stability effect, avoiding the situation of displacement and sliding due to insufficient positioning during the assembly process, so as to improve the installation accuracy, and the plurality of protective balls arranged on the lower surface of the pressing plate are all made of rubber material. On the one hand, it protects the surface of the fitting and absorbs the impact force during processing. On the other hand, after the assembly is completed, it avoids mutual friction between the fitting and the pressing plate, so as to realize the separation of the fitting and the pressing plate.

Specific implementation mode

[0020] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] Example 1, refer to Figures 1 - 13 , a multi-station bolt processing machine tool, including a support platform 1 and a fixed seat 2, the fixed seat 2 is connected with a robotic arm 3, and further includes: A stabilizing component 4, the stabilizing component 4 is fixedly connected to the support platform 1, and the stabilizing component 4 is used for stabilizing the assembled parts after positioning; A positioning component 5, the positioning component 5 is located above the support platform 1, and the positioning component 5 is used for positioning the assembled parts; A transmission component 6, the transmission component 6 is connected to the support platform 1, and the transmission component 6 is used for intermittently driving the assembled parts.

[0022] Further, there are several fixing seats 2, and the several fixing seats 2 are circumferentially arrayed about the central axis of the support table 1. One end of the fixing seat 2 is fixedly connected to the side wall of the support table 1, and the other end of the fixing seat 2 is fixedly connected to the corresponding robotic arm 3; there are several fixing seats 2, and the several fixing seats 2 are circumferentially arrayed about the central axis of the support table 1. One end of the fixing seat 2 is fixedly connected to the side wall of the support table 1, and the other end of the fixing seat 2 is fixedly connected to the corresponding robotic arm 3; the positioning assembly 5 includes a placement rack plate 51. There are three groups of placement rack plates 51, and each group has three placement rack plates 51. A second magnet 7 is fixedly connected to the side wall of one of the placement rack plates 51 in each group. A first bidirectional lead screw 54 and a second bidirectional lead screw 57 are respectively rotatably connected inside the placement rack plate 51. A first motor 52 and a second motor 56 are respectively fixedly connected to the two side walls of the placement rack plate 51. One end of the first bidirectional lead screw 54 is fixedly connected to the first motor 52, and one end of the second bidirectional lead screw 57 is fixedly connected to the second motor 56. The first bidirectional lead screw 54 and the second bidirectional lead screw 57 are vertically staggered inside the placement rack plate 51; both ends of the first bidirectional lead screw 54 are threadedly connected to a first clamping plate 53. Several rotation rods 531 distributed linearly in an array are rotatably connected to the side plate of the first clamping plate 53. Both ends of the second bidirectional lead screw 57 are threadedly connected to a second clamping plate 55. Both the first clamping plate 53 and the second clamping plate 55 are slidably connected to the placement rack plate 51.

[0023] Initial fixing of the assembled parts by the positioning assembly 5: During the process of installing bolts on the assembled parts, first, the assembled parts are placed on the surface of each group of placement rack plates 51 by an external manipulator. Then, the external controller first starts the first motor 52 to drive the first bidirectional lead screw 54 to rotate, and then the first bidirectional lead screw 54 moves through the threaded connection with the first clamping plate 53, and then the clamping is adjusted adaptively according to the size of the assembled parts. Moreover, the rotation rods 531 are made of rubber material, which can protect the outer surface of the assembled parts and avoid damage during the positioning process. After that, the second motor 56 is controlled to drive the second bidirectional lead screw 57 to rotate, so that the second clamping plates 55 approach each other, thereby adjusting and positioning the other two sides of the assembled parts. During this process, if the assembled parts are not in the middle position, then one side of the assembled parts is pushed during the process of the second clamping plates 55 approaching each other, and the rotation of the rotation rods 531 promotes the change of the position of the assembled parts, so as to complete the position calibration of the assembled parts for the subsequent precise installation of bolts. And through the setting of multiple robotic arms 3, multiple bolts can be clamped and assembled synchronously, improving the processing efficiency.

[0024] Refer to Figures 8 - 13, Further, the transmission assembly 6 includes an operating table 61 which is located above the support table 1. A limiting ring 67 is fixedly connected to the side wall of the support table 1, and a number of tooth teeth 66 distributed in a circumferential array are fixedly connected to the inner wall of the limiting ring 67; the transmission assembly 6 further includes a third motor 62 and a support ring 63. The support ring 63 is fixedly connected to the upper side wall of the support table 1, and the third motor 62 is fixedly connected to the lower side wall of the support table 1. The inner wall of the support ring 63 is slidably limited between the limiting ring 67. A number of grooves 632 distributed in a circumferential array are formed on the upper side wall of the support ring 63. A convex block 631 and a stabilizing spring 633 are provided inside the groove 632. The convex block 631 is slidably limited between the inner wall of the groove 632. The two ends of the stabilizing spring 633 are respectively fixedly connected to the side wall of the convex block 631 and the inner wall of the groove 632; an active turntable 64 is provided inside the support ring 63. The side wall of the active turntable 64 is fixedly connected to one end of the third motor 62. A receiving groove 68 is formed on one side of the active turntable 64. A plug rod 65 meshing with the tooth teeth 66 is slidably connected to the inner wall of the receiving groove 68. A telescopic spring 69 is provided inside the receiving groove 68. The two ends of the telescopic spring 69 are respectively fixedly connected to the inner wall of the receiving groove 68 and the side wall of one end of the plug rod 65.

[0025] Adjustment of the assembly by the transmission assembly 6: After the assembly is initially fixed, the third motor 62 is controlled to start working through external programming, so that it drives the active turntable 64 to start rotating. In this process, as the active turntable 64 rotates, it will drive the outer plug rod 65 to mesh with the corresponding tooth teeth 66. Then, as the active turntable 64 continues to rotate, the plug rod 65 will contract into the inside of the receiving groove 68 and compress the telescopic spring 69. At the same time, the operating table 61 is driven to rotate through the sliding limit between the limiting ring 67 and the support ring 63, so that the multiple positioning assemblies 5 change their initial positions, so as to adjust the assembly to below the robotic arm 3 and wait for the installation of the bolts. And every time the active turntable 64 rotates one circle, the operating table 61 can be driven to rotate one-third of a circle, so as to transport each assembled workpiece to below the corresponding robotic arm 3. At this time, the robotic arm 3 can be controlled to dock and install the clamped bolt with the mounting hole on the assembly, so as to complete the assembly of the bolt; During the rotation of the active turntable 64, when driving the operation table 61 to rotate, each group of positioned fittings will be transported below the robotic arm 3 at this time, and the assembled ones will be sent out from below the robotic arm 3, and the manipulator in the blanking area will take them off. After blanking, the positioning component 5 will rotate to the feeding area to wait for feeding. With the continuous rotation of the active turntable 64, the plugging rod 65 will gradually move away from the tooth 66, and the plugging rod 65 will also gradually reset through the elastic recovery of the telescopic spring 69. When the plugging rod 65 is separated from the tooth 66, the operation table 61 stops rotating, but the active turntable 64 will continue to rotate. At this time, the operation table 61 is in an idle period. At this time, not only the feeding and assembly processes are synchronously completed, but also the blanking of the fittings can be completed. When the plugging rod 65 contacts the tooth 66 next time, the robotic arm 3 has completed the installation and achieved reset, and at the same time, the positioning component 5 has also completed the positioning. Through the intermittent rotation of the operation table 61, non-stop operation is realized, improving the processing efficiency. In addition, in the initial state, the stabilizing spring 633 is in a compressed state. At this time, the elastic force of the stabilizing spring 633 will push up the convex block 631, so that the upper end of the convex block 631 is in close contact with the side wall of the operation table 61. When the operation table 61 stops rotating, the mutual force between the two is used to ensure the stability effect of the operation table 61 to improve the accuracy during bolt installation. And when the operation table 61 rotates, the side wall of the operation table 61 will slide relative to the convex block 631 to ensure the smooth rotation of the operation table 61.

[0026] Embodiment 2, refer to Figure 6 and Figure 7, further; a movable hole 205 is formed in the side wall of one of the fixed seats 2, a sliding rod 204 is slidably connected to the inner wall of the movable hole 205, one end of the sliding rod 204 is fixedly connected to a return spring 203, and the end of the return spring 203 away from the sliding rod 204 is fixedly connected to the side wall of the fixed seat 2. A sliding plate 201 is fixedly connected to the side wall of the sliding rod 204. The sliding plate 201 is trapezoidally arranged. A first magnet 202 is fixedly connected to the end of the sliding plate 201 away from the fixed seat 2; the stabilizing assembly 4 includes an arc-shaped plate 44. Fixed cylinders 41 and movable rods 42 are provided at both ends of the arc-shaped plate 44. The movable rod 42 is "T"-shaped. A pressing spring 47 is sleeved on the outer wall of the movable rod 42. One end of the movable rod 42 is fixedly connected to the side wall of the arc-shaped plate 44, and the other end of the movable rod 42 is slidably connected to the inner wall of the fixed cylinder 41. One end of the fixed cylinder 41 is fixedly connected to the side wall of the support table 1. The fixed cylinder 41 is located outside the operation table 61. Both ends of the pressing spring 47 are respectively fixedly connected to the inner wall of the fixed cylinder 41 and the side wall of the movable rod 42; a plurality of pressing plates 43 distributed in a circumferential array are fixedly connected to the side wall of the arc-shaped plate 44. The pressing plate 43 is "U"-shaped. A plurality of protective balls 431 distributed in a linear array are rotatably connected to the side wall of the pressing plate 43. A vertical plate 45 is fixedly connected to the side wall of the arc-shaped plate 44. A sliding hole 46 is formed in the side wall of the vertical plate 45. The inner wall of the sliding hole 46 is slidably connected to the sliding plate 201.

[0027] The stabilizing component 4 strengthens the assembled parts after positioning: a magnetic block 27 is installed on the placement frame 51 in the middle of each group, and the magnetism of the end of the magnetic block 27 away from the placement frame 51 is of the same polarity as the magnetism of the end of the magnetic block 1 202 away from the fixed seat 2. Therefore, during the rotation of the operating table 61, when the corresponding magnetic block 27 moves to an appropriate range, an interaction force will be generated between the magnetic block 27 and the magnetic block 1 202. Through the principle of like-sex magnets repelling each other, the sliding rod 204 is driven to slide inside the movable hole 205, and the reset spring 203 is stretched at the same time. The size of the movable hole 205 is larger than the sliding plate 201. When the sliding rod 204 moves, the sliding plate 201 is driven to move synchronously. In addition, in the initial state, the mutual limitation between the sliding plate 201 and the sliding hole 46 makes the arc plate 44 in a lifted state, and the height of the arc plate 44 is higher than that after positioning. The height of the assembly part, and the action of the movable rod 42 makes the clamping spring 47 in a compressed state. When the sliding plate 201 moves to one side of the fixed seat 2, the sliding connection between the inclined surface at one end and the sliding hole 46, and the elastic recovery of the clamping spring 47 can drive the arc plate 44 to move downward and close to the upper end of the assembly part, and the sliding between the movable rod 42 and the fixed cylinder 41 can ensure the stability of the arc plate 44 during the downward movement. When the magnetic block 27 moves to the same horizontal line as the magnetic block 1 202, the force between the two is the largest, and the sliding plate 201 also moves to the farthest distance. At this time, the elastic recovery of the clamping spring 47 makes the clamping plate 43 pressed against the upper surface of the assembly part, thereby further promoting the positioning of the assembly part, improving its stabilization effect, avoiding displacement and sliding during the assembly process, and improving the accuracy of installation; In addition, the assembly part has a certain height, and the length of the vertical plate 45 is limited. When the sliding plate 201 moves to the farthest distance, it will not disengage from the sliding hole 46, but keep a certain distance between its inclined surface and the sliding hole 46 to ensure the smooth extrusion of the pressure plate 43, and the multiple protective balls 431 arranged on the lower surface of the pressure plate 43 are all made of rubber material. On the one hand, the surface of the assembly part is protected, and when the impact force generated during the bolt assembly acts, it can absorb part of the impact energy through its own deformation, thereby playing a buffering effect. On the other hand, after the assembly is completed, with the rotation of the operating table 61, in order to avoid mutual friction between the assembly part and the pressure plate 43, the assembly part and the pressure plate 43 are separated by squeezing and rotating the protective balls 431. When the corresponding magnetic block 207 gradually moves away from the magnetic block 1 202, the sliding plate 201 is reset by the elastic recovery of the reset spring 203, thereby lifting the arc plate 44 to reset it, and the elasticity of the reset spring 203 is greater than the elasticity of the clamping spring 47 to ensure the smooth reset of the pressure plate 43 and wait for the next work.

[0028] It should be noted that the specific model and specifications of the motor need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail here.
