Description

[0001] The present invention relates to the technical field of metal spraying, and in particular to an efficient conveying device for spraying metal pipe fittings. Background Art

[0002] At present, with the development of industry, the use of metal pipe fittings has improved the stability of liquid and gas transportation. At the same time, the service life of metal pipe fittings is longer than that of other materials. During the processing of metal pipe fittings, different technological processes are required to ensure that the quality of the processed pipe fittings meets the use standards.

[0003] Currently, when spraying metal pipe fittings, the pipe fittings need to be fixed first and then rotated at a constant speed. The spraying gun is used to spray evenly on the surface of the pipe fittings. However, during the conveying of the pipe fittings, due to the different diameters of the pipe fittings, when switching between pipe fittings of different diameters, it is necessary to manually adjust the height of the support frame, which greatly affects the spraying efficiency.

At this time, under the action of the moving mechanism and the adjusting mechanism, the linear distance of the rotation of the adjusting mechanism decreases.

[0021] 2. Through the rotational connection between the supporting rotating rod and the fixed inclined rod and the setting of the hard rubber material of the supporting rotating rod in the present invention, when the metal pipe fitting is being fixed, it will generate a horizontal displacement itself, effectively avoiding scratches on the metal pipe fitting during the moving process.

Detailed implementation manners

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] It can be understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0034] As Figure 1 , Figure 4 and Figure 5 shown, in one embodiment, an efficient conveying device for spraying metal pipe fittings is proposed, and the device includes:

[0035] Main body frame 1: including a mounting frame 101 provided on the main body frame 1;

[0036] Supporting mechanism 2: It includes four supporting rotating rods 201 that are inclinedly installed on the installation frame 101 for supporting metal pipe fittings. The supporting rotating rods 201 are made of rigid rubber, and each supporting rotating rod 201 is rotatably installed on the fixed inclined rod 202. The fixed inclined rod 202 is fixedly installed on the fixing plate 203, and the fixing plate 203 is fixedly installed on the surface of the connecting rod 204;

[0037] Feedback mechanism 3: It is used to feedback the displacement amount for metal pipe fittings with different diameters;

[0038] Moving mechanism 4: It changes the linear distance of rotation by cooperating with the adjusting mechanism 5;

[0039] Lifting mechanism 6: It is used to drive the supporting rotating rod 201 to run to the feeding position;

[0040] Driving mechanism 7: It is used to drive the supporting rotating rod 201 to rise.

[0041] When the embodiment of the present invention is actually applied, when spraying the metal pipe fittings, at this time, the metal pipe fittings are placed on the supporting rotating rod 201 through an external conveying device. As Figure 4 shown, when viewed from the Figure 4 front view direction, at this time, the outer wall of the metal pipe fitting squeezes the feedback mechanism 3 to move downward. Through the action of the feedback mechanism 3, the moving mechanism 4 and the adjusting mechanism 5 are driven to adjust the linear distance of rotation. At this time, through the driving action of the driving mechanism 7, the adjusting mechanism 5 drives the lifting mechanism 6 to move, and then drives the metal pipe fitting to rise a certain distance to reach a fixed position, so as to achieve the effect of automatically driving the metal pipe fitting to reach the pre-fixed position. At the same time, when the diameter of the metal pipe fitting changes, at this time, the moving distance of the extrusion feedback mechanism 3 also changes accordingly. Taking the increase in the diameter of the metal pipe fitting as an example, when the diameter of the metal pipe fitting increases, at this time, due to the inclined state of the supporting rotating rod 201, the distance that the metal pipe fitting squeezes the feedback mechanism 3 to move downward decreases accordingly. As Figure 5As shown, at this time, under the action of the moving mechanism 4 and the adjusting mechanism 5, the linear distance by which the adjusting mechanism 5 rotates is reduced. At this time, the rising distance of the rising mechanism 6 driven by the driving mechanism 7 also decreases accordingly, so that the central axis of the metal pipe fitting will still rise to the height of the central axis of the required fixed position. It should be noted here that when the diameter of the metal pipe fitting is changed, the distance from the center of the vertical section of the corresponding metal pipe fitting to the intersection point of the extension lines of the two fixed inclined rods 202 also changes accordingly. Different metal pipe fittings form a right triangle through the center of the circle, the tangent point in contact with the supporting rotating rod 201, and the intersection point of the extension lines of the fixed inclined rods 202. At the same time, the right triangles formed by different metal pipe fittings are similar. Therefore, the distance from the center of the vertical section of the metal pipe fitting to the intersection point of the extension line of the fixed inclined rod 202 is in a proportional relationship. Therefore, changing the distance of the extrusion feedback mechanism 3 is also in a proportional relationship, so as to achieve the purpose of automatically changing the rising height of the metal pipe fitting according to the diameter of the metal pipe fitting. At the same time, through the rotational connection between the supporting rotating rod 201 and the fixed inclined rod 202 and the setting of the hard rubber material of the supporting rotating rod 201, when the metal pipe fitting is fixed, it will generate a horizontal displacement itself, effectively avoiding scratches on the metal pipe fitting during the movement process.

[0042] As Figure 3 , Figure 4 , Figure 5 and Figure 8 shown, as a preferred embodiment of the present invention, the feedback mechanism 3 includes a pressure receiving rod 301 in contact with the metal pipe fitting. A rolling ball is rotatably installed at the contact end of the pressure receiving rod 301 with the metal pipe fitting. The pressure receiving rod 301 penetrates through the fixing plate 203 and the connecting rod 204 and is slidably connected to the fixing plate 203 and the connecting rod 204. The other end of the pressure receiving rod 301 is fixedly installed on the surface of the moving right-angle block 302. A tension spring 308 is fixedly installed on the surface of the moving right-angle block 302, and the other end of the tension spring 308 is connected to the rising mechanism 6. A swing rod 303 is rotatably installed on the surface of the moving right-angle block 302. One end of the swing rod 303 away from the moving right-angle block 302 is rotatably connected to the sliding block 304. The sliding block 304 is slidably connected to the rising mechanism 6. A driving tooth plate 305 is fixedly installed on the surface of the sliding block 304. The driving tooth plate 305 meshes with the rotating gear 306. The rotating gear 306 is rotatably installed on the rising mechanism 6, and the rotating gear 306 meshes with the driven tooth plate 307. The driven tooth plate 307 is slidably connected to the rising mechanism 6.

[0043] When the present invention embodiment is actually applied, when the metal pipe fitting is placed on the supporting rotating rod 201, as Figure 4 shown, from Figure 4When viewed from the front view direction, at this time, the outer wall of the metal pipe fitting presses the pressure rod 301 to move downward. The downward movement of the pressure rod 301 drives the moving right-angle block 302 to move downward synchronously, and then drives the sliding block 304 to move leftward through the swinging action of the swinging rod 303. As shown in Figure 5 shown, when viewed from the Figure 5 front view direction, the movement of the sliding block 304 drives the moving mechanism 4 to move leftward. As the radius of the metal pipe fitting increases, the distance that the pressure rod 301 moves downward decreases, and then the distance that the moving mechanism 4 moves leftward decreases. At this time, the rotation radius of the moving mechanism 4 decreases. As shown in Figure 8 shown, when viewed from the Figure 8 front view direction, at the same time, the movement of the sliding block 304 drives the adjusting mechanism 5 to move rightward through the transmission of the rack and gear. The decrease in the movement distance of the pressure rod 301 also drives the adjusting mechanism 5 to move rightward by a smaller distance, and then enables the adjusting mechanism 5 to always cooperate with the moving mechanism 4, thus ensuring the cooperation relationship between the adjusting mechanism 5 and the moving mechanism 4, so that under the driving action of the driving mechanism 7, metal pipe fittings with different diameters are driven to reach the corresponding pre-fixed positions.

[0044] As shown in Figure 5 shown, as another preferred embodiment of the present invention, the moving mechanism 4 includes a follower shaft 401 fixedly installed on the sliding block 304. The other end of the follower shaft 401 is fixedly installed with a moving cone pulley 402. The surface of the moving cone pulley 402 is fixedly installed with a sliding shaft 403, and the sliding shaft 403 is slidably connected to the driving mechanism 7.

[0045] In the actual application of the embodiment of the present invention, as shown in Figure 5 shown, when the sliding block 304 moves leftward, at this time, the moving cone pulley 402 is driven to move leftward synchronously through the follower shaft 401. As the diameter of the metal pipe fitting increases, the distance that the moving cone pulley 402 moves leftward decreases, thereby reducing the rotation radius of the moving cone pulley 402. At the same time, the state of the adjusting mechanism 5 is changed through the action of the feedback mechanism 3, so that the adjusting mechanism 5 always maintains a meshing relationship with the moving mechanism 4. Therefore, when the number of rotation turns of the driving mechanism 7 is constant, by increasing the diameter of the metal pipe fitting, the linear distance of the rotation of the moving cone pulley 402 is reduced, and then the rising height of the metal pipe fitting is reduced, so that for a large-diameter metal pipe fitting, its central axis still rises to a fixed central axis position, improving the positioning efficiency of the metal pipe fitting.

[0046] As shown in Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, as another preferred embodiment of the present invention, the adjusting mechanism 5 includes an L-shaped adjusting rod 501 fixedly installed on the driven tooth plate 307. A linkage cylinder 502 is rotatably installed on the surface of the L-shaped adjusting rod 501. A plurality of linkage rods 503 are rotatably installed on the surface of the linkage cylinder 502. The other end of each linkage rod 503 is rotatably connected to a moving tooth 504. The moving tooth 504 is slidably connected to the inner wall of the driven runner 505. One end of the moving tooth 504 is bent, and the bending angle is the same as the conical angle of the moving cone wheel 402. At the same time, the moving tooth 504 meshes with the moving cone wheel 402.

[0047] In the actual application of the embodiment of the present invention, as Figure 5 and Figure 8 shown, when the driven tooth plate 307 moves to the right, it drives the L-shaped adjusting rod 501 to move to the right synchronously at this time. The rightward movement of the L-shaped adjusting rod 501 drives the linkage cylinder 502 to move to the right. As Figure 6 shown, from Figure 6 the front view direction, and then drives the moving tooth 504 to move towards the central axis of the driven runner 505 through the swinging action of the linkage rod 503. When the diameter of the metal pipe fitting is increased, at this time, the feedback mechanism 3 reduces the leftward movement distance of the moving mechanism 4, that is, reduces the rotation radius of the moving mechanism 4. At this time, under the action of the feedback mechanism 3, the movement distance of the adjusting mechanism 5 is synchronously reduced, that is, the distance of the moving tooth 504 approaching the central axis of the driven runner 505 is reduced, so that the moving tooth 504 always cooperates and meshes with the moving cone wheel 402. At the same time, as the diameter of the metal pipe increases, the linear distance of the rotation of the driven runner 505 is reduced, so as to achieve the purpose that for metal pipe diameters of different sizes, they can all move to the central axis of the same pre-fixed position.

[0048] As Figure 2 and Figure 5 shown, as another preferred embodiment of the present invention, the rising mechanism 6 includes a rising shaft 601 fixedly installed on the surface of the driven runner 505. Rising gears 602 are fixedly installed at the other ends of the rising shafts 601. The rising gears 602 mesh with a tooth plate 603. The tooth plate 603 is fixedly installed on the mounting frame 101. The teeth on the two tooth plates 603 are rotationally symmetrically arranged. A guide rod 605 is fixedly installed on the surface of each tooth plate 603. The shaft end of the driven runner 505 is rotatably installed on a rising platform 604, and the guide rod 605 passes through the rising platform 604 and is slidably connected to the rising platform 604. The sliding block 304 is slidably connected to the rising platform 604. The other end of the tension spring 308 is connected to the rising platform 604. A rotating gear 306 is rotatably installed on the rising platform 604. The driven tooth plate 307 is slidably connected to the rising platform 604. The connecting rod 204 passes through the rising platform 604 and is fixedly connected to the rising platform 604.

[0049] In the actual application of the embodiment of the present invention, as Figure 5 shown, when the driving mechanism 7 drives the moving mechanism 4 to rotate, at this time, the moving mechanism 4 drives the adjusting mechanism 5 to rotate, and the rotation of the adjusting mechanism 5 drives the rising shaft 601 to rotate, thereby driving the rising gear 602 to rotate. At this time, through the meshing action of the rising gear 602 and the tooth plate 603, as Figure 2 shown, it drives the rising gear 602 to move upward, thereby driving the rising platform 604 to move upward, so that the metal pipe fitting rises to the pre-fixed position. By changing the diameter of the metal pipe fitting and adjusting the positions of the moving mechanism 4 and the adjusting mechanism 5 through the feedback mechanism 3, the rising height of the rising platform 604 is changed, so as to achieve the purpose of automatically adjusting the movement position.

[0050] As Figure 5 and Figure 9 shown, as another preferred embodiment of the present invention, the driving mechanism 7 includes a driving motor 701 fixedly installed on the rising platform 604. The output end of the driving motor 701 penetrates through the rising platform 604 and is rotatably connected to the rising platform 604. A driving bevel gear 702 is fixedly installed at the output end of the driving motor 701. The driving bevel gear 702 meshes with a driven bevel gear 703, and the driven bevel gear 703 penetrates through the rising platform 604 and is rotatably connected to the rising platform 604. The inner wall of the driven bevel gear 703 is slidably connected to the sliding shaft 403.

[0051] In the actual application of the embodiment of the present invention, when the adjustment of the moving mechanism 4 and the adjusting mechanism 5 is completed by the movement of the feedback mechanism 3 being extruded by the surface of the metal pipe fitting, as Figure 9 shown, at this time, the driving motor 701 starts to operate. The operation of the driving motor 701 drives the driven bevel gear 703 to rotate through the transmission of the bevel gear set, as Figure 5 shown, thereby driving the sliding shaft 403 to rotate. Through the cooperation of the moving mechanism 4 and the adjusting mechanism 5, the rising mechanism 6 is driven to rotate, thereby driving the metal pipe fitting to move upward, so as to achieve the purpose of automatically driving the metal pipe fitting to rise to the pre-fixed position.

[0052] As Figure 1 shown, as another preferred embodiment of the present invention, a rotating motor 102 is fixedly installed on the installation frame 101. The output end of the rotating motor 102 penetrates through the installation frame 101 and is rotatably connected to the installation frame 101. A rotating chuck 103 is fixedly installed at the output end of the rotating motor 102. A pipe fitting fixator 104 for fixing the metal pipe fitting is clamped on the rotating chuck 103. The installation frame 101 is also fixedly installed with a displacement connector 105, and another pipe fitting fixator 104 is fixedly installed on the displacement connector 105.

[0053] In the actual application of the embodiments of the present invention, after the position movement of the metal pipe fitting is completed, such as Figure 1 shown, at this time, the pipe fitting fixator 104 is driven by the displacement connector 105 to move towards the position of the metal pipe fitting. Through the pushing action of the pipe fitting fixator 104 on the displacement connector 105, the metal pipe fitting is moved horizontally. When the other end of the metal pipe fitting is squeezed by the pipe fitting fixator 104 on the rotating chuck 103, the displacement connector 105 stops moving at this time. At the same time, the two pipe fitting fixators 104 fix the inner wall of the metal pipe fitting to avoid the problem of slipping when driving the metal pipe fitting to rotate. After the fixation of the metal pipe fitting is completed at this time, the rotating motor 102 starts to operate, and the metal pipe fitting is driven by the rotating chuck 103 to rotate at a constant speed, so as to fully spray the surface of the metal pipe fitting through the spray gun.

For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
