Description
Technical Field
[0001] This invention relates to the field of metal coating technology, and in particular to a high-efficiency positioning and clamping device for thermal spraying. Background Technology
[0002] With the development of industry, metals are being used more and more widely, and the technology of metal surface coating is constantly being optimized. The coating formed by spraying on the surface of metal greatly improves the corrosion resistance of metal. At the same time, thermal spraying can be used to spray a wide range of coating materials, and thermal spraying technology can be used to spray most solid engineering materials.
[0003] Currently, in the process of thermal spraying steel pipes, the steel pipe is clamped and rotated, and the surface of the steel pipe is sprayed by the reciprocating motion of the thermal spray nozzle. However, existing equipment fixes one end of the steel pipe with the gripper of the machine tool and then rotates it. This method means that the position gripped by the gripper cannot be sprayed during the spraying process, and a second spraying is required, which greatly affects the efficiency of the spraying.
[0004] Based on this, the present invention designs a high-efficiency positioning and clamping device for thermal spraying to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a high-efficiency positioning and clamping device for thermal spraying, which aims to solve the technical problems existing in the prior art mentioned in the background.
[0006] The present invention is implemented as follows: a high-efficiency positioning and clamping device for thermal spraying, the device comprising:
[0007] Main frame: including mounting platform on the main frame, on which steel pipes to be sprayed are placed, and clearance grooves are provided on the mounting platform;
[0008] Fixed mechanism: includes multiple movable swing arms mounted on the mounting platform, each movable swing arm has a limit wheel rotatably mounted on its surface, and a fixed swing arm is rotatably mounted on the other end of the limit wheel;
[0009] Counter-pressure mechanism: used to drive the limit wheel to press tightly against the inner wall of the steel pipe to be sprayed;
[0010] Lateral movement mechanism: Through its cooperation with the drive mechanism, it drives the limit wheel to extend into the interior of the steel pipe to be sprayed;
[0011] Support mechanism: It works in conjunction with the drive mechanism to detach from the steel pipe to be coated.
[0012] Furthermore, the counter-pressure mechanism includes two conical blocks mounted on the mounting platform. Each conical block has a counter-pressure spring fixedly mounted on its inner wall. The end of the counter-pressure spring away from the conical block is connected to the surface of the moving column. The conical block and the surface of the moving column are slidably connected. A linkage rod is fixedly mounted on the surface of the conical block. The linkage rod passes through the moving column and is slidably connected to the moving column. A movable swing rod is rotatably connected to the surface of the linkage rod. A fixed swing rod is rotatably connected to the surface of the moving column.
[0013] Furthermore, the transverse movement mechanism includes a rotating cylinder mounted on a mounting platform. A bidirectional lead screw is fixedly installed inside the rotating cylinder. The bidirectional lead screw and two lead screw sliders form a helical pair transmission. Each lead screw slider is slidably connected to the mounting platform. A moving column passes through the lead screw slider and is rotatably connected to the lead screw slider. The surface of the rotating cylinder is provided with a first straight groove, a helical groove, and a second straight groove that cooperate with the driving mechanism. The first straight groove, the helical groove, and the second straight groove are connected in sequence.
[0014] Furthermore, the support mechanism includes a support cylinder rotatably mounted on the mounting platform. The surface of the support cylinder is provided with a first arc-shaped groove, a support straight groove, and a second arc-shaped groove that cooperate with the drive mechanism. The first arc-shaped groove, the support straight groove, and the second arc-shaped groove are connected in sequence. A support rod is fixedly mounted on the surface of the support cylinder, and the surface of the support rod is in contact with the steel pipe to be sprayed.
[0015] Furthermore, the driving mechanism includes a drive motor fixedly mounted on the mounting platform. The output end of the drive motor passes through the mounting platform and is rotatably connected to the mounting platform. A rotating lead screw is fixedly mounted on the output end of the drive motor. The rotating lead screw and the drive slider form a helical pair transmission. A thrust rod is fixedly mounted on the surface of the drive slider. The two ends of the thrust rod contact the inner walls of the support straight groove and the helical groove, respectively.
[0016] Furthermore, the device also includes a rotating mechanism, which includes a rotating motor fixedly mounted on the mounting platform. The output end of the rotating motor passes through the mounting platform and is rotatably connected to the mounting platform. A rotating slide rod is fixedly mounted on the output end of the rotating motor, and the rotating slide rod is slidably connected to the moving column.
[0017] Furthermore, the contact ends of the thrust rod with the support straight groove and the spiral groove are all provided with rolling balls.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] 1. This invention uses an external driving device to drive a counter-pressure mechanism to rotate. The rotation of the counter-pressure mechanism drives the limiting wheel to rotate synchronously, which in turn drives the steel pipe to be sprayed to rotate. Due to the circular design of the limiting wheel, the inside of the steel pipe to be sprayed is stably limited, preventing the steel pipe from slipping during rotation. Combined with the external reciprocating thermal spray nozzle, the surface of the steel pipe to be sprayed is automatically and evenly sprayed, avoiding the need for secondary back spraying on the outer circumference and improving the spraying efficiency of thermal spraying.
[0020] 2. In this invention, the supporting mechanism is driven by the driving mechanism to rotate. As the supporting mechanism drives the steel pipe to be coated to rotate into the relief groove, the steel pipe to be coated is blocked by the mounting platform and rolls down the slope of the mounting platform into the collection device, thereby completing the automatic unloading of the steel pipe to be coated.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0034] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.
[0035] like Figure 1 and Figure 2 As shown, in one embodiment, a high-efficiency positioning and clamping device for thermal spraying is proposed, the device comprising:
[0036] Main frame 1: includes a mounting platform 101 set on the main frame 1, on which a steel pipe 102 to be sprayed is placed, and a clearance groove 103 is provided on the mounting platform 101;
[0037] Fixed mechanism 2: includes multiple movable rocker arms 202 mounted on the mounting platform 101, each movable rocker arm 202 has a limit wheel 201 rotatably mounted on its surface, and a fixed rocker arm 203 is rotatably mounted on the other end of the limit wheel 201;
[0038] Counter-pressure mechanism 3: used to drive the limit wheel 201 to adhere tightly to the inner wall of the steel pipe 102 to be sprayed;
[0039] Transverse movement mechanism 4: Through its cooperation with the drive mechanism 6, it drives the limit wheel 201 to extend into the interior of the steel pipe 102 to be sprayed;
[0040] Support mechanism 5: It works in conjunction with drive mechanism 6 to detach from the steel pipe 102 to be sprayed.
[0041] In practical applications, when performing thermal spraying on the steel pipe 102 to be coated, as in the embodiments of the present invention... Figure 1 As shown, the steel pipe 102 to be coated is placed on the support groove 503 by external equipment. The drive mechanism 6 and the transverse movement mechanism 4 then drive the counter-pressure mechanisms 3 at both ends to move towards the middle position of the steel pipe 102, thereby causing the limit wheel 201 to move into the interior of the steel pipe 102. At this point, under the reaction force of the counter-pressure mechanism 3 squeezed by the steel pipe 102, as... Figure 2 As shown, at this time, the movable swing arm 202 and the fixed swing arm 203 swing, which in turn drives the limiting wheel 201 to move away from the central axis of the steel pipe 102 to be sprayed, until the limiting wheel 201 is pressed tightly against the inner wall of the steel pipe 102 to be sprayed, thereby automatically clamping and fixing the steel pipe 102 to be sprayed. Through the action of the drive mechanism 6 and the support mechanism 5, the support mechanism 5 no longer supports the steel pipe 102 to be sprayed. At this time, the steel pipe 102 to be sprayed is completely fixed and limited by the limiting wheel 201. At this time, the external drive device drives the counter-pressure mechanism 3 to rotate. The rotation of the counter-pressure mechanism 3 drives the limiting wheel 201 to rotate synchronously, which in turn drives the steel pipe 102 to rotate. Figure 2 As shown, due to the circular design of the limiting wheel 201, the inside of the steel pipe 102 to be sprayed is stably limited, preventing the steel pipe 102 from rotating and slipping. Combined with the reciprocating thermal spray nozzle, the surface of the steel pipe 102 is automatically and evenly sprayed, avoiding the need for secondary back spraying on the outer circumference and improving the spraying efficiency of thermal spraying. After spraying is completed, the device is reset by the reverse movement of the drive mechanism 6. The device is still supported by the support mechanism 5. After the drive mechanism 6 reverses to the reset, it continues to reverse. At this time, the drive mechanism 6 drives the support mechanism 5 to rotate. As the support mechanism 5 drives the steel pipe 102 to be sprayed to rotate into the relief groove 103, it is blocked by the mounting platform 101, causing the steel pipe 102 to roll down the slope of the mounting platform 101 into the collection device, thus completing the automatic unloading of the steel pipe 102.
[0042] like Figure 3 and Figure 4As shown, in a preferred embodiment of the present invention, the counter-pressure mechanism 3 includes two conical blocks 301 mounted on the mounting platform 101. A counter-pressure spring 302 is fixedly mounted on the inner wall of each conical block 301. The end of the counter-pressure spring 302 away from the conical block 301 is connected to the surface of the moving column 304. The conical block 301 is slidably connected to the surface of the moving column 304. A linkage rod 303 is fixedly mounted on the surface of the conical block 301. The linkage rod 303 passes through the moving column 304 and is slidably connected to the moving column 304. A movable swing rod 202 is rotatably connected to the surface of the linkage rod 303. A fixed swing rod 203 is rotatably connected to the surface of the moving column 304.
[0043] In practical application, when the steel pipe 102 to be sprayed is fixed, the conical blocks 301 at both ends move towards the middle of the steel pipe 102 under the action of the driving mechanism 6 and the transverse moving mechanism 4. As the conical blocks 301 contact the steel pipe 102, the reaction force of the steel pipe 102 causes the conical blocks 301 at both ends to move in opposite directions relative to the moving column 304. At this time, the counter-pressure spring 302 is compressed. Figure 4 As shown, from Figure 4 Looking from the front, the leftward movement of the conical block 301 drives the linkage rod 303 to move to the left simultaneously. This, in turn, causes the limiting wheel 201 to move away from the central axis of the steel pipe 102 to be sprayed through the swinging of the moving swing rod 202 and the fixed swing rod 203. At this time, the limiting wheel 201 presses against the inner wall of the steel pipe 102 to be sprayed, thereby achieving the purpose of automatically fixing and clamping the steel pipe 102 to be sprayed. At the same time, the conical shape of the conical block 301 allows for fixing steel pipes 102 of different diameters, thereby increasing the versatility of the device and improving the stability of the lateral fixing of the steel pipe 102 to be sprayed.
[0044] like Figure 9 , Figure 10 and Figure 11 As shown, in another preferred embodiment of the present invention, the transverse movement mechanism 4 includes a rotating cylinder 401 mounted on a mounting platform 101. A bidirectional lead screw 402 is fixedly mounted inside the rotating cylinder 401. The bidirectional lead screw 402 and two lead screw sliders 403 form a helical transmission pair. Each lead screw slider 403 is slidably connected to the mounting platform 101. A moving column 304 passes through the lead screw slider 403 and is rotatably connected to the lead screw slider 403. The surface of the rotating cylinder 401 is provided with a first straight groove 404, a helical groove 405 and a second straight groove 406 that cooperate with the drive mechanism 6. The first straight groove 404, the helical groove 405 and the second straight groove 406 are connected in sequence.
[0045] In practical applications, when fixing the steel pipe 102 to be sprayed, as in the embodiments of the present invention... Figure 10As shown, at this time, the rotating cylinder 401 is driven to rotate by the action of the drive mechanism 6 and the spiral groove 405. Figure 11 As shown, the rotation of the rotating cylinder 401 drives the bidirectional lead screw 402 to rotate synchronously. The rotation of the bidirectional lead screw 402 drives the lead screw sliders 403 at both ends to move towards each other through the reverse thread and helical pair transmission, which in turn drives the conical blocks 301 to move towards each other. Through the cooperation of the counter-pressure mechanism 3 and the fixing mechanism 2, the steel pipe 102 to be sprayed is clamped and fixed. After the steel pipe 102 to be sprayed is fixed by the limit wheel 201, the drive mechanism 6 drives the support mechanism 5 to move. At the same time, due to the action of the second straight groove 406, the drive mechanism 6 will not drive the rotating cylinder 401 to rotate. At this time, the movement of the support mechanism 5 no longer affects the rotation of the steel pipe 102. The sprayed steel pipe 102 is supported to prevent friction between the pipe and the support mechanism 5 when the pipe rotates, thus avoiding affecting the quality of thermal spraying. After spraying is completed, the drive mechanism 6 moves in the opposite direction to reset the support mechanism 5. At the same time, the limit wheel 201 is reset through the cooperation of the drive mechanism 6 and the transverse mechanism 4. As the drive mechanism 6 continues to move in the opposite direction, the rotating cylinder 401 will not rotate due to its cooperation with the first straight groove 404. The support mechanism 5 is rotated through the cooperation of the drive mechanism 6 and the support mechanism 5 to unload the steel pipe 102, thus avoiding motion interference during unloading.
[0046] like Figure 7 and Figure 8 As shown, in another preferred embodiment of the present invention, the support mechanism 5 includes a support cylinder 501 rotatably mounted on the mounting platform 101. The surface of the support cylinder 501 is provided with a first arc-shaped groove 502, a support straight groove 503 and a second arc-shaped groove 504 that cooperate with the drive mechanism 6. The first arc-shaped groove 502, the support straight groove 503 and the second arc-shaped groove 504 are connected in sequence. A support rod 505 is fixedly mounted on the surface of the support cylinder 501. The surface of the support rod 505 is in contact with the steel pipe 102 to be sprayed.
[0047] In practical applications, when the steel pipe 102 to be sprayed is fixed by the action of the driving mechanism 6 and the transverse moving mechanism 4, as shown in the embodiments of the present invention... Figure 8As shown, at this time, the drive mechanism 6, through its cooperation with the support groove 503, prevents the support cylinder 501 from rotating, meaning the support rod 505 also does not rotate. The support rod 505 continuously supports the steel pipe 102 to be sprayed. Once the steel pipe 102 is fixed, the drive mechanism 6, through the action of the second arc groove 504, drives the support cylinder 501 to rotate, which in turn drives the support rod 505 to rotate. At this point, the support rod 505 no longer supports the steel pipe 102 to be sprayed, thus preventing the steel pipe 102 from rotating. 2. Friction is caused during spraying. After the hot spraying of the steel pipe 102 to be sprayed is completed, the reverse movement of the drive mechanism 6 drives the support mechanism 5 to support the steel pipe 102 to be sprayed again. As the drive mechanism 6 drives the limit wheel 201 to reset through the transverse movement mechanism 4, the continued movement of the drive mechanism 6 drives the support rod 505 to rotate through the first arc groove 502. Then, when the support rod 505 passes through the clearance groove 103, the steel pipe 102 to be sprayed is stably fed under the limiting action of the mounting platform 101.
[0048] like Figure 5 , Figure 6 and Figure 11 As shown, in another preferred embodiment of the present invention, the driving mechanism 6 includes a driving motor 601 fixedly mounted on the mounting platform 101. The output end of the driving motor 601 passes through the mounting platform 101 and is rotatably connected to the mounting platform 101. A rotating lead screw 602 is fixedly mounted on the output end of the driving motor 601. The rotating lead screw 602 and the driving slider 603 form a helical pair transmission. A thrust rod 604 is fixedly mounted on the surface of the driving slider 603. The two ends of the thrust rod 604 are in contact with the inner walls of the supporting straight groove 503 and the helical groove 405, respectively.
[0049] In practical applications, when clamping and fixing the steel pipe 102 to be sprayed, as in the embodiments of the present invention... Figure 5 and Figure 11 As shown, at this time, the drive motor 601 starts running. The operation of the drive motor 601 drives the rotating lead screw 602 to rotate, which in turn drives the drive slider 603 to move laterally through the helical pair transmission. The movement of the drive slider 603 drives the push rod 604 to move laterally in sync. Figure 6 As shown, at this time, the thrust rod 604 clamps and fixes the steel pipe 102 to be sprayed by cooperating with the sliding groove on the rotating cylinder 401 and the supporting cylinder 501, without affecting the thermal spraying quality of the steel pipe 102. After the steel pipe 102 is sprayed, the reverse operation of the drive motor 601, and the cooperation of the thrust rod 604, the rotating cylinder 401 and the sliding groove on the supporting cylinder 501, complete the reset of the device and the stable feeding of the steel pipe 102 to be sprayed.
[0050] like Figure 1 and Figure 2 As shown, in another preferred embodiment of the present invention, the device further includes a rotating mechanism 7, which includes a rotating motor 701 fixedly mounted on the mounting platform 101. The output end of the rotating motor 701 passes through the mounting platform 101 and is rotatably connected to the mounting platform 101. A rotating slide rod 702 is fixedly mounted on the output end of the rotating motor 701 and is slidably connected to the moving column 304.
[0051] In practical applications of this invention, after the steel pipe 102 to be sprayed is fixed, as follows: Figure 1 and Figure 2 As shown, the rotating motor 701 starts running at this time. The operation of the rotating motor 701 drives the rotating slide bar 702 to rotate, which in turn drives the moving column 304 to rotate. The rotation of the moving column 304 drives the limit wheel 201 to rotate through the connection of the mechanism, which in turn drives the steel pipe 102 to be sprayed to rotate, thereby achieving the purpose of stable rotation for spraying.
[0052] like Figure 6 As shown, in another preferred embodiment of the present invention, the contact ends of the thrust rod 604 with the support straight groove 503 and the spiral groove 405 are provided with rolling balls.
[0053] In practical applications, the embodiments of the present invention, such as Figure 6 As shown, by setting a ball on the thrust rod 604, the thrust rod 604 converts the sliding groove into rolling friction during movement, thereby increasing the service life and stability of the device.

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