Description

Technical Field

[0001] This invention mainly relates to the technical field of diaphragm compressor processing, specifically to a robotic welding process for diaphragm compressor chassis. Background Technology

[0002] A diaphragm compressor is a compressor that relies on the deformation of a diaphragm to change the cylinder volume. Currently, in order to speed up production efficiency, the chassis of diaphragm compressors are often welded by robots.

[0003] When welding a diaphragm compressor to its chassis, the welding slag produced during the welding process falls into the weld seam, obstructing the view and making it difficult to inspect the welding quality. In addition, the large area of ​​welding slag spatter will also lead to a large amount of labor and time being spent on subsequent grinding and cleaning, increasing manufacturing costs. Summary of the Invention

[0004] This invention provides a robotic welding process for diaphragm compressor chassis to solve the technical problems mentioned in the background section.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A robotic welding process for a diaphragm compressor chassis includes the following steps:

[0007] Step 1: The welding head is moved by the multi-axis connecting arm in the welding robot until it can be moved to the part to be welded on the chassis of the diaphragm compressor.

[0008] Step 2: Use the telescopic lever to block the welding slag generated during the welding of the diaphragm compressor chassis until the welding of the diaphragm compressor chassis is completed;

[0009] Step 3: Drive the telescopic lever through the power mechanism to shorten the telescopic lever and bring it closer to the welding head.

[0010] Furthermore, the welding robot includes a base, with a multi-axis connecting arm connected to the top of the base. A welding head is connected to the end of the multi-axis connecting arm away from the base, and the outside of the welding head is connected to a shielding mechanism. In this invention, the base provides support for the multi-axis connecting arm, and the multi-axis connecting arm drives the welding head to move.

[0011] Furthermore, the shielding mechanism includes a connecting ring connected to the outer surface of the welding head, a support plate connected to the lower surface of the connecting ring and sleeved on the outside of the welding head, and rotating shielding components connected to both sides of the support plate. The two rotating shielding components are connected to the power mechanism.

[0012] The upper surface of the support plate is connected to two protruding plates at both ends. The protruding plates are symmetrically arranged on both sides of the rotating shielding assembly. In this invention, the support plate provides support for the rotating shielding assembly, and the rotating shielding assembly shields the welding slag generated when welding the diaphragm compressor chassis.

[0013] Furthermore, the rotating shielding assembly includes a rotating rod connected between the two protruding plates at the same end, and a plurality of telescopic stops inserted into the rotating rod. In this invention, the two rows of telescopic stops can maintain their contact with the diaphragm compressor and the chassis respectively, thereby providing shielding function while providing support for the welding head.

[0014] Furthermore, the telescopic stop lever includes a guide rod inserted into the rotating rod housing, a shielding sleeve sleeved on the outside of one end of the guide rod, and a spring sleeved on the outside of the other end of the guide rod. One end of the spring abuts against the outer surface of the shielding sleeve, and the other end of the spring abuts against the outer surface of the guide rod. In this invention, the guide rod provides guidance for the sliding of the shielding sleeve, and the sliding of the shielding sleeve on the guide rod enables the telescopic stop lever to extend and retract according to the shape of the diaphragm compressor and its chassis surface.

[0015] Furthermore, one end of the guide rod is connected to an electromagnet, and one side of the electromagnet is connected to a permanent magnet. The permanent magnet is connected to the inner surface of one end of the shielding sleeve. The electromagnet and the permanent magnet are placed in a manner where their magnetic poles attract each other. In this invention, the magnetic attraction force generated by the electromagnet is used to attract the permanent magnet. Since the permanent magnet is connected to the shielding sleeve, it pulls the shielding sleeve back.

[0016] Furthermore, an anti-sucking sleeve is connected inside the shielding sleeve, and a sliding ring is slidably connected inside the anti-sucking sleeve. The sliding ring is sleeved on the outside of the electromagnet. Both the sliding ring and the anti-sucking sleeve are made of rubber. In this invention, the anti-sucking sleeve reduces the influence of the electromagnet on the shielding sleeve, and the sliding ring slides inside the anti-sucking sleeve.

[0017] Furthermore, the power mechanism includes a motor connected to the upper surface of the convex plate and symmetrically arranged, a worm gear connected to the output shaft of the motor, and a worm wheel meshing with the worm gear. The worm wheel is coaxially arranged with the adjacent rotating rod. In this invention, the motor drives the worm gear connected to its output shaft, the worm gear drives the worm wheel connected to it, and the worm wheel drives the rotating rod, so that multiple telescopic stops connected to the rotating rod rotate synchronously.

[0018] Furthermore, a gear is connected to the end of the worm gear away from the motor, and a rack is meshed with one end of the gear. The rack is slidably connected to the lower surface of the support plate, and a sliding rheostat is connected to one side of the rack. The sliding rheostat is connected to the lower surface of the support plate and is electrically connected to the electromagnet. In this invention, the sliding rheostat changes the magnetic force of the electromagnet connected to it, so that when the telescopic lever approaches the convex plate, the telescopic lever shortens.

[0019] Furthermore, the lower surface of the support plate is connected to a guide groove, and a slider is slidably connected in the groove. The slider is connected to the upper surface of the rack. In this invention, the slider is guided to slide by the guide groove.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] Firstly, the present invention can provide slag shielding according to the plane of the diaphragm compressor and its chassis, thereby reducing the impact of slag on welding. Specifically, a guide rod is used to guide the sliding of the shielding sleeve. By sliding the shielding sleeve on the guide rod, the telescopic stop bar can extend and retract according to the surface shape of the diaphragm compressor and its chassis, thereby fitting the diaphragm compressor and its chassis surface to shield the slag.

[0022] Secondly, the present invention uses the magnetic attraction force generated by the electromagnet to attract the permanent magnet. Since the permanent magnet is connected to the blocking sleeve, it pulls the blocking sleeve back, thereby shortening the telescopic stop bar. This reduces the obstruction caused by the telescopic stop bar, making it easier to determine the position of the diaphragm compressor and the chassis, thus facilitating the welding between the diaphragm compressor and the chassis.

Detailed Implementation

However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] For an example, please refer to the appendix. Figure 1-6 A robotic welding process for a diaphragm compressor chassis includes the following steps:

[0035] Step 1: The welding head 13 is moved by the multi-axis connecting arm 12 in the welding robot 10 until the welding head 13 can be moved to the part to be welded on the chassis of the diaphragm compressor.

[0036] Step 2: Use telescopic lever 232 to block the welding slag generated during the welding of the diaphragm compressor chassis until the welding of the diaphragm compressor chassis is completed;

[0037] Step 3: Drive the telescopic stop bar 232 through the power mechanism 24, so that the telescopic stop bar 232 shortens and moves closer to the welding head 13.

[0038] For details, please refer to the appendix. Figure 1-3 The welding robot 10 includes a base 11, a multi-axis connecting arm 12 connected to the top of the base 11, a welding head 13 connected to the end of the multi-axis connecting arm 12 away from the base 11, and the outside of the welding head 13 connected to the shielding mechanism 20.

[0039] The shielding mechanism 20 includes a connecting ring 21 connected to the outer surface of the welding head 13, a support plate 22 connected to the lower surface of the connecting ring 21 and sleeved on the outside of the welding head 13, and rotating shielding components 23 connected to both sides of the support plate 22. The two rotating shielding components 23 are connected to the power mechanism 24.

[0040] The upper surface of the support plate 22 is connected to both ends of the protruding plates 223, which are symmetrically arranged on both sides of the rotating shielding assembly 23.

[0041] The rotating shielding assembly 23 includes a rotating rod 231 connected between the two protruding plates 223 at the same end, and a plurality of telescopic stops 232 inserted into the rotating rod 231;

[0042] It should be noted that in this embodiment, the base 11 provides support for the multi-axis connecting arm 12, and the multi-axis connecting arm 12 drives the welding head 13 to move so that the welding head 13 can be moved to the welding part of the diaphragm compressor chassis.

[0043] Furthermore, the support plate 22 provides support for the rotating shielding assembly 23, which in turn shields the welding slag generated during the welding of the diaphragm compressor chassis, reducing slag spatter and facilitating simultaneous welding by the welding robot and workers.

[0044] Furthermore, by rotating the lever 231, the telescopic lever 232 is rotated to adjust the angle of the telescopic lever 232 so that the two rows of telescopic levers 232 can maintain contact with the diaphragm compressor and the chassis respectively. Thus, the telescopic lever 232 provides a shielding function while providing support for the welding head 13.

[0045] For details, please refer to the appendix. Figure 3-5The telescopic stop lever 232 includes a guide rod 2321 inserted into the housing of the rotating rod 231, a cover sleeve 2322 sleeved on the outside of one end of the guide rod 2321, and a spring 2323 sleeved on the outside of the other end of the guide rod 2321. One end of the spring 2323 abuts against the outer surface of the cover sleeve 2322, and the other end of the spring 2323 abuts against the outer surface of the guide rod 2321.

[0046] One end of the guide rod 2321 is connected to an electromagnet 2324, and one side of the electromagnet 2324 is connected to a permanent magnet 2325. The permanent magnet 2325 is connected to the inner surface of one end of the shielding sleeve 2322. The electromagnet 2324 and the permanent magnet 2325 are placed in a manner where their magnetic poles attract each other.

[0047] The shielding sleeve 2322 is internally connected to an anti-sucking sleeve 2326, and the anti-sucking sleeve 2326 is internally slidably connected to a sliding ring 2327. The sliding ring 2327 is sleeved on the outside of the electromagnet 2324. Both the sliding ring 2327 and the anti-sucking sleeve 2326 are made of rubber.

[0048] It should be noted that in this embodiment, the guide rod 2321 provides guidance for the sliding of the shielding sleeve 2322. The sliding of the shielding sleeve 2322 on the guide rod 2321 enables the telescopic stop rod 232 to extend and retract according to the shape of the diaphragm compressor and its chassis surface, thereby fitting the diaphragm compressor and its chassis surface to shield the welding slag.

[0049] Furthermore, the magnetic attraction force generated by the electromagnet 2324 is used to attract the permanent magnet 2325. Since the permanent magnet 2325 is connected to the blocking sleeve 2322, it pulls the blocking sleeve 2322 back, thereby shortening the telescopic lever 232. This reduces the obstruction caused by the telescopic lever 232, making it easier to judge the position of the diaphragm compressor and the chassis, and thus facilitating the welding between the diaphragm compressor and the chassis.

[0050] Furthermore, the anti-sucking sleeve 2326 reduces the influence of the electromagnet 2324 on the blocking sleeve 2322, and the sliding ring 2327 slides within the anti-sucking sleeve 2326, thereby providing resistance to the sliding and reducing the influence of inertia, so that the telescopic lever 232 can extend and retract stably.

[0051] For details, please refer to the appendix. Figure 2 and 3 The power mechanism 24 includes a motor 241 connected to the upper surface of the convex plate 223 and symmetrically arranged, a worm 242 connected to the output shaft of the motor 241, and a worm wheel 243 meshing with the worm 242. The worm wheel 243 is coaxially arranged with the adjacent rotating rod 231.

[0052] The end of the worm gear 242 away from the motor 241 is connected to a gear 244, and one end of the gear 244 is meshed with a rack 245. The rack 245 is slidably connected to the lower surface of the support plate 22. A sliding rheostat 246 is connected to one side of the rack 245. The sliding rheostat 246 is connected to the lower surface of the support plate 22 and is electrically connected to the electromagnet 2324.

[0053] The lower surface of the support plate 22 is connected to a guide groove 221, and a slider 222 is slidably connected in the groove of the guide groove 221. The slider 222 is connected to the upper surface of the rack 245.

[0054] It should be noted that in this embodiment, the motor 241 drives the worm 242 connected to its output shaft, the worm 242 drives the worm wheel 243 connected to it, and the worm wheel 243 drives the rotating rod 231, so that the multiple telescopic stops 232 connected to the rotating rod 231 rotate synchronously. The cooperation between the worm wheel 243 and the worm 242 forms a self-locking structure, reducing the rotation of the telescopic stops 232 caused by external forces.

[0055] Furthermore, when the worm gear 242 rotates, it drives the gear 244 on its rod to rotate, which in turn drives the sliding rheostat 246 connected to it, so that the sliding rheostat 246 changes the magnetic force of the electromagnet 2324 connected to it, thereby shortening the telescopic lever 232 when it approaches the convex plate 223.

[0056] Furthermore, the slider 222 is guided to slide by the guide groove 221.

[0057] The specific operation method of this invention is as follows:

[0058] The welding head 13 is moved by the multi-axis connecting arm 12 in the welding robot 10 until it can be moved to the part of the diaphragm compressor chassis to be welded; the welding slag generated during the welding of the diaphragm compressor chassis is blocked by the telescopic stop bar 232 until the welding of the diaphragm compressor chassis is completed.

[0059] The power mechanism 24 drives the telescopic stop bar 232, causing the telescopic stop bar 232 to shorten and approach the welding head 13, waiting for the next welding.

[0060] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
