Description

Technical Field

[0001] This invention relates to the field of compressor welding technology, specifically to a compressor component processing and welding equipment. Background Technology

[0002] During the machining and welding process of compressor components, it is necessary to position the components to be welded before welding to ensure their stability during the welding process. The compressor components involved in this application are mainly cylindrical, annular, arc-shaped, or near-cylindrical metal parts that require stable positioning during welding, including compressor housings, compressor cylinders, upper housing covers, lower housing covers, end covers, liquid receiver cylinders, muffler housings, connecting sleeves, pipe fittings, flanges, and mounting brackets. Because these compressor components have cylindrical, annular, or arc-shaped structural features, effective positioning of their sidewalls is required during welding to ensure that the compressor components are in the required machining positions.

[0003] When positioning compressor components, clamping only a single position is insufficient to meet the positioning needs of different positions on the side wall. It is necessary to clamp or press the lower and upper areas of the side wall of the compressor components separately, and to ensure that the positioning actions at different positions can cooperate with each other. At the same time, different compressor components have different external dimensions, and the clamping and pressing structure also needs to be able to be adjusted according to the size of the compressor components to adapt to the positioning requirements of different compressor components.

[0004] During the clamping process, the clamping structure may continue to generate a certain relative displacement after contacting the compressor components. Therefore, it is necessary to form a corresponding buffer during the clamping process to avoid a sudden increase in clamping force and to ensure that the clamping action of the lower side wall of the compressor components and the pressing action of the upper side wall can be coordinated. At the same time, when positioning the compressor components at different positions, it is also necessary to coordinate the driving actions between different positioning mechanisms to complete the synchronous positioning of the compressor components.

[0005] In view of this, this technical solution proposes a compressor component processing and welding equipment. Summary of the Invention

[0013] As a further embodiment of the present invention: the buffer clamping plate (109) includes a contact plate (1090) and a fixed back plate (1091) arranged in parallel. The bottom of the fixed back plate (1091) is fixed on the connecting base plate (104). A buffer cavity (1092) is provided between the contact plate (1090) and the fixed back plate (1091). An elastic buffer member is provided in the buffer cavity (1092). A guide hole is provided on the fixed back plate (1091).

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the lower part of the side wall of the compressor component is clamped and fixed by the bottom side clamping mechanism, and the upper part of the side wall of the compressor component is flipped and squeezed and fixed by the flipping side pressing mechanism. While the servo motor drives the flipping side pressing mechanism to run, the bottom side clamping mechanism is driven to run synchronously through the power connection component, so that different positions of the compressor component can be positioned synchronously; when the flipping ring rotates, the contact area between the spiral outer pressure plate and the compressor component gradually transitions from a smaller radial dimension area to a larger radial dimension area, so that the lateral pressing force is gradually formed, and the lateral pressing can be gradually released when rotating in the opposite direction. By detachably connecting the spiral outer pressure plate to the outer wall of the rotating ring cylinder, spiral outer pressure plates with different spiral thicknesses can be replaced according to different compressor parts. The buffer clamping plate provides buffer stroke through the contact plate, fixed back plate and elastic buffer in the buffer cavity. When the ball nut continues to move, it can absorb part of the displacement, avoid sudden increase of clamping force, and provide synchronous action margin for the spiral outer pressure plate to continue to complete the rotating clamping. This enables the rapid positioning of compressor parts and improves energy utilization. Attached Figure Description

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Please see Figures 1-6 A compressor component processing and welding equipment includes a base 1, a component fixing platform 2 is provided at the top center of the base 1, the component fixing platform 2 is used to quickly position the compressor component to be processed and welded, and a welding device is provided on one side of the top of the component fixing platform 2. After the compressor component is fixed to the required position, the welding device is started to perform welding operation. Specifically, the welding device is used to weld compressor parts that have been positioned by the bottom side clamping mechanism 10 and the flip-type side pressing mechanism 20; the welding device is any one of a gas metal arc welding device, a tungsten inert gas welding device or a laser welding device, preferably a gas metal arc welding device suitable for welding steel compressor housings, connecting pipes, mounting brackets and end caps.

[0031] In a preferred embodiment, the welding apparatus includes a welding power source, a welding torch, a wire feeding mechanism, a shielding gas supply mechanism, a welding torch position adjustment mechanism, and a controller; the welding torch is mounted on one side of the component fixing platform 2 via the welding torch position adjustment mechanism, which can adjust at least the lateral position, longitudinal position, and height position of the welding torch, so that the end of the welding torch can correspond to the welding position of compressor components of different sizes.

[0032] The welding torch position adjustment mechanism can be a manual adjustment mechanism consisting of a linear guide rail, a slider and a lead screw adjustment assembly, or an automatic adjustment mechanism consisting of an electric linear module; when an automatic adjustment mechanism is used, its driving part is a servo motor or a stepper motor.

[0033] Preferably, when the compressor parts to be welded are ordinary carbon steel or low alloy steel structural parts, the welding device adopts a gas metal arc welding structure, the welding wire diameter can be 0.8 to 1.2 mm, the welding current is selected according to the thickness of the workpiece plate as 80 to 300 A, and the shielding gas flow rate is 10 to 20 L / min; the above values ​​are only as an feasible preferred range and do not constitute a limitation on the scope of protection of the present invention.

[0034] Its working principle is as follows: an electric arc is established between the welding wire or welding electrode and the area to be welded of the compressor component by the welding power source, so that the position to be welded is locally melted to form a molten pool, and the possibility of oxidation or porosity caused by contact between oxygen and nitrogen in the air and the molten pool is reduced by the shielding gas; as the welding torch moves along the welding trajectory, the molten pool cools and solidifies to form a weld, thereby realizing the fixed connection between different compressor components.

[0035] When the workpiece has high requirements for heat input, weld width or deformation, a laser welding device can also be used. A focused laser beam is used to act on the part to be welded to form a molten pool, and the welding is completed by moving the welding gun or laser welding head along the predetermined weld trajectory.

[0036] Two sets of longitudinally distributed positioning units are provided on the upper side of the component fixing platform 2. These are a bottom lateral clamping mechanism 10, which moves horizontally relative to the upper side of the component fixing platform 2 for clamping, and a flipping lateral pressing mechanism 20 located above the bottom lateral clamping mechanism 10. The bottom lateral clamping mechanism 10 is used to clamp and fix the lower part of the side wall of the compressor component placed on the component fixing platform 2. The flipping lateral pressing mechanism 20 performs longitudinal flipping and pressing to fix the upper part of the side wall of the compressor component. At the same time, the flipping lateral pressing mechanism 20 is driven by a servo motor 3, and the power end of the servo motor 3 also drives the bottom lateral clamping mechanism 10 to run synchronously through a power connection component 30. This enables the bottom lateral clamping mechanism 10 and the flipping lateral pressing mechanism 20 to be driven synchronously by a single servo motor 3 to fix the lower part and upper middle part of the side wall of the compressor component placed on the component fixing platform 2. This facilitates fast and efficient positioning while also improving energy utilization.

[0037] Specifically, such as Figures 1-4 , Figure 7 As shown, the flipping lateral pressing mechanism 20 includes a rotating base ring 206 supported by multiple evenly distributed support columns 4. Multiple flipping ring cylinders 200 are evenly spaced along the upper edge of the rotating base ring 206. The inner wall of the flipping ring cylinder 200 is provided with a ring of flipping ring cylinder inner tooth grooves 202. At the same time, a ring of flipping drive toothed columns 207 is installed on the top wall of the rotating base ring 206. The flipping drive toothed columns 207 are meshed and rotatably connected with the flipping ring cylinder inner tooth grooves 202. That is, when the rotating base ring 206 rotates, it controls the rotating base ring 206 to rotate along the flipping ring cylinder inner tooth grooves 202 on the inner wall of the flipping ring cylinder 200, thereby driving the flipping ring cylinder 200 to rotate. The rotating base ring 206 has a horizontally arranged circular structure, and its central axis is substantially coincident with the central axis of the component fixing platform 2. This allows the multiple rotating ring cylinders 200 arranged circumferentially around the compressor components placed on the component fixing platform 2 to be evenly distributed. Preferably, there are 3 to 8 rotating ring cylinders 200, more preferably 4, 6, or 8, arranged at equal angles along the circumference of the rotating base ring 206. The included angle between the centers of two adjacent rotating ring cylinders 200 can be determined based on the number of rotating ring cylinders 200. For example, when there are 4 rotating ring cylinders, the included angle between the centers of adjacent rotating ring cylinders 200 is approximately 90°, and when there are 6, it is approximately 60°.

[0038] Furthermore, a lateral toothed groove 208 is provided on the outer circumferential wall of the rotating base ring 206. A drive gear 209 meshes with one side of the lateral toothed groove 208. The top of the drive gear 209 is connected to the drive shaft of the servo motor 3 through a connecting shaft 210. That is, under the operation of the servo motor 3, the connecting shaft 210 is driven to control the drive gear 209 to rotate, which in turn drives the lateral toothed groove 208 to drive the rotating base ring 206 to rotate. Then, by utilizing the meshing rotation between the flipping drive toothed column 207 and the toothed groove 202 inside the flipping ring cylinder, the flipping ring cylinder 200 is controlled to flip. That is, by adjusting the rotation direction of the servo motor 3, the flipping direction of the flipping ring cylinder 200 can be indirectly controlled. To achieve the flipping and pressing of the compressor component sidewall placed on the component fixing platform 2 by utilizing the flipping of the flipping ring cylinder 200, a detachable spiral pressing outer plate is provided on the outer wall 201 of the outer flipping ring cylinder 200. The spiral pressing outer plate is composed of multiple spiral outer pressing plates 203. A locking pin 204 is installed on the inner side of the spiral outer pressing plate 203. The locking pin 204 has a corresponding locking groove 205 on the outer wall of the outer flipping ring cylinder 201. Through the locking between the locking pin 204 and the locking groove 205, the detachable connection between the spiral outer pressing plate 203 and the outer wall 201 of the flipping ring cylinder is realized. In this way, according to the size of different compressor components, spiral outer pressing plates 203 with different spiral thicknesses can be replaced to form a spiral pressing outer plate that can stably contact and gradually flip and press the sidewall of the compressor component, thereby increasing the applicability of this technical solution. The number of 204 pins can be set depending on the actual installation situation, and there is no limit to it here.

[0039] It should be noted that the structural form and meshing transmission principle between the flipping drive tooth 207 and the inner tooth groove 202 of the flipping ring cylinder are as follows: the flipping drive tooth 207 is set on the rotating base ring 206 and moves synchronously with the rotating base ring 206; the inner tooth groove 202 of the flipping ring cylinder is set along the inner circumferential wall of the flipping ring cylinder 200; the flipping drive tooth 207 and the inner tooth groove 202 of the flipping ring cylinder mesh with each other, thereby forming a meshing transmission structure that can convert the rotational motion of the rotating base ring 206 into the flipping motion of the flipping ring cylinder 200 itself.

[0040] Specifically, the flipping drive tooth 207 is configured with multiple tooth-shaped protrusions spaced apart circumferentially along the rotating base ring 206, the tooth shape, tooth pitch and tooth thickness of which are adapted to the tooth groove 202 inside the flipping ring cylinder; the tooth groove 202 inside the flipping ring cylinder is provided with multiple tooth grooves that cooperate with the flipping drive tooth 207 along the inner circumferential direction of the flipping ring cylinder 200; the flipping drive tooth 207 and the tooth groove 202 inside the flipping ring cylinder adopt a straight tooth meshing structure, or an oblique tooth meshing structure according to the requirements of transmission smoothness, preferably adopting a straight tooth meshing structure that is simple in structure and easy to process and assemble.

[0041] When the servo motor 3 drives the rotating base ring 206 to rotate via the drive gear 209 and the lateral toothed groove 208, the tilting drive pinion 207 mounted on the rotating base ring 206 moves synchronously with the rotating base ring 206. Since the tilting drive pinion 207 is engaged with the toothed groove 202 inside the tilting ring cylinder, the tilting drive pinion 207 applies a driving force along the tooth surface direction to the toothed groove 202 inside the tilting ring cylinder during its movement. This driving force generates a torque around the axis of the tilting ring cylinder 200, thereby driving the tilting ring cylinder 200 to rotate around its own axis.

[0042] When the rotation direction of the rotating base ring 206 changes, the driving direction of the flipping drive tooth column 207 relative to the inner tooth groove 202 of the flipping ring cylinder changes accordingly, causing the flipping ring cylinder 200 to rotate in the opposite direction, thereby realizing the pressing and releasing action of the spiral outer pressure plate 203.

[0043] Preferably, the tilting drive gear 207 and the tilting ring inner tooth groove 202 are made of 45 steel, 40Cr steel, or other metal materials with high strength and wear resistance; their meshing tooth surfaces can be tempered, surface hardened, or nitrided to improve wear resistance and service life. A tooth flank clearance is maintained between the tilting drive gear 207 and the tilting ring inner tooth groove 202 to ensure normal meshing rotation, thus avoiding jamming due to machining or assembly errors.

[0044] Preferably, each spiral outer pressure plate 203 has a reinforcing strip 212 on its outer pressing surface, which extends along the length or inclination of the spiral outer pressure plate 203. The reinforcing strip 212 serves two purposes: firstly, to improve the bending stiffness of the spiral outer pressure plate 203 under radial reaction force; and secondly, to increase the contact friction between the reinforcing strip and the surface of the compressor components. The reinforcing strip 212 can be a metal rib integrally machined with the spiral outer pressure plate 203, or a wear-resistant polyurethane strip or rubber strip fixed by screws or adhesive. When the surface of the components to be processed has been coated or has high appearance requirements, an elastic wear-resistant material is preferred. Preferably, the two sides of the servo motor 3 are fixed to the base 1 by fixing rods 211, and the bottom center of the drive gear 209 is connected to the bottom side clamping mechanism 10 by power connection assembly 30.

[0045] It should be noted that multiple spiral external pressure plates 203 are connected sequentially along the outer circumference of the rotating ring cylinder 200, forming a spiral pressing surface with a gradually changing thickness along the circumference of the rotating ring cylinder 200. The term "spiral" refers to the fact that the radial distance of the spiral external pressure plates 203 relative to the central axis of the rotating ring cylinder 200 is different at different circumferential positions, so that the effective radial dimension at the contact position with the compressor components gradually increases or decreases during the rotation of the rotating ring cylinder 200.

[0046] When rotating in the clamping direction, the contact area between the spiral outer pressure plate 203 and the compressor components gradually transitions from a smaller radial dimension area to a larger radial dimension area, thereby gradually reducing the gap between the spiral outer pressure plate 203 and the compressor components and forming a lateral clamping force; when rotating in the opposite direction, the contact area moves to a smaller radial dimension position, thereby gradually releasing the lateral clamping force.

[0047] Preferably, 3 to 8 spiral outer pressure plates 203 are installed on the outer periphery of each rotating ring cylinder 200, more preferably 4 to 6; the difference between the maximum radial thickness and the minimum radial thickness of a single spiral outer pressure plate 203 can be 3 to 20 mm, preferably 5 to 12 mm, so as to form a continuous and relatively gentle pressing stroke.

[0048] The main body of the spiral external pressure plate 203 can be made of 45 steel, 40Cr steel or aluminum alloy. It is preferable to provide a polyurethane, nitrile rubber or other wear-resistant elastic layer with a thickness of 2 to 8 mm on the side close to the compressor parts to reduce metal hard contact that could cause scratches or local indentations on the compressor housing.

[0049] The locking pin 204 is preferably configured as a cylindrical pin, a ball-head locating pin, or a T-shaped locating pin, and the locking groove 205 is machined as an axial insertion groove or an L-shaped locking groove that matches the locking pin 204. Each spiral outer pressure plate 203 is preferably provided with at least two locking pins 204 to suppress the warping and circumferential movement of the spiral outer pressure plate 203 during the compression process.

[0050] like Figure 1 , Figure 8 As shown, the bottom of the support column 4 is fixed on the base 1, and a T-shaped slider 31 is installed on the top. The T-shaped slider 31 is set as a T-shaped structure. At the same time, the bottom of the rotating base ring 206 corresponding to the T-shaped slider 31 is provided with an annular T-shaped groove 32 that is adapted to rotate with the T-shaped slider 31. That is, the T-shaped slider 31 is placed in the annular T-shaped groove 32 and rotates. Then, under the action of multiple support columns 4, the rotating base ring 206 is kept to rotate stably.

[0051] Furthermore, such as Figures 1-6As shown, the bottom-side clamping mechanism 10 includes a clamping moving groove 100 opened inside the component fixing platform 2. The top of the clamping moving groove 100 and the end facing the servo motor 3 are both open. Two lead screws 101 are rotatably arranged inside the clamping moving groove 100. The threads of the two lead screws 101 are opposite and are fixedly connected by a connecting block 102. A ball nut 103 is threadedly connected to each of the two lead screws 101. The ball nut 103 is provided with a guide device for limiting its rotation. The end of the lead screw 101 away from the end opening of the clamping moving groove 100 is rotatably arranged in the inner wall of the clamping moving groove 100 through a connecting rod and a bearing. The other end of the lead screw 101 is connected to the power connection assembly 30 through a connecting rod. That is, the two lead screws 101 are driven to rotate by the power connection assembly 30, and then the ball nut 103 is controlled to move along the corresponding lead screw 101. That is, the movement direction of the two ball nuts 103 is adjusted by changing the rotation direction of the servo motor 3. A support base plate 105 is mounted on the top of the ball nut 103, and an mounting plate 108 is mounted on the top of the support base plate 105. The two mounting plates 108 are connected to a connecting base plate 104 on the side that is close to each other through a telescopic component. A buffer clamping plate 109 with a "V" shaped structure is mounted on the top of the connecting base plate 104. That is, the initial position of the buffer clamping plate 109 is adjusted by the telescopic component, and then the movement of the ball nut 103 controls the two buffer clamping plates 109 to move closer to each other to clamp the lower side wall of the compressor component, or to move away to release. That is, the clamping movement and the flipping of the upper flipping ring cylinder 200 control the spiral external pressure plate 203 to press the side wall of the compressor component synchronously. It should be noted that the lead screw 101 is preferably a ball screw or a trapezoidal lead screw; when a smaller transmission resistance and a higher positioning accuracy are required, a ball screw is preferred; the two lead screws 101 are arranged coaxially and have opposite thread directions, and the two lead screws 101 are coaxially fixedly connected by a connecting block 102 so that the two lead screws 101 can rotate synchronously. Two ball nuts 103 are threadedly connected to two lead screws 101 with opposite directions of rotation. Therefore, when the two lead screws 101 rotate synchronously in the same direction, the two ball nuts 103 can synchronously approach or move away from each other along the axial direction of the lead screws 101. The support base plate 105 is a rectangular or approximately rectangular metal plate and is connected to the top of the ball nuts 103 by bolt fixing, positioning pin fixing or welding.

[0052] The guiding device is used to restrict the ball nut 103 from rotating along with the lead screw 101. Preferably, the guiding device includes a linear guide rail arranged along the length of the clamping moving groove 100 and a slider that slides with the linear guide rail. The slider is fixedly connected to the support base plate 105 or the ball nut 103. When the lead screw 101 rotates, the linear guide rail restricts the ball nut 103 from rotating around the axis of the lead screw 101, so that the rotational motion between the lead screw 101 and the ball nut 103 is converted into linear motion of the ball nut 103 along the length of the clamping moving groove 100.

[0053] The linear guide is preferably provided in one set on one side of the lead screw 101 or in two sets parallel to each other on both sides of the lead screw 101 to improve the anti-sway capability of the support base plate 105 during movement; or a guide device can be formed by a guide groove provided on the side wall of the clamping moving groove 100 and a guide block provided on the ball nut 103 or the support base plate 105.

[0054] Preferably, the telescopic component includes two screws 107 and a screw cylinder 106. The two screws 107 are threaded to both ends of the screw cylinder 106. The length of the two screws 107 at both ends is adjusted by rotating the screw cylinder 106. The ends of the two screws 107 away from the screw cylinder 106 are connected to the mounting plate 108 and the connecting base plate 104, thereby realizing the initial position adjustment of the buffer clamping plate 109. To maintain the movement of the two side buffer clamping plates 109 closer to each other, and to ensure that the lateral clamping of the compressor components is consistent with the flipping and pressing of the upper spiral outer pressure plate 203, a certain buffering process is required. That is, the buffer clamping plate 109 includes: a contact plate 1090 and a fixed back plate 1091 arranged parallel on both sides. The bottom of the fixed back plate 1091 is fixed on the connecting base plate 104. A buffer cavity 1092 is provided between the contact plate 1090 and the fixed back plate 1091. That is, the buffer cavity 1092 provides a buffer stroke for the contact clamping between the contact plate 1090 and the compressor components. Specifically, an elastic buffer is provided in the buffer cavity 1092. The elastic buffer is one or more of a compression spring, a disc spring, a polyurethane elastic block, or a rubber elastic block. Preferably, 2 to 6 compression springs are evenly distributed along the length of the contact plate 1090. At least two guide holes are provided on the fixed back plate 1091. A guide rod that slides with the guide hole is provided on the side of the contact plate 1090 near the fixed back plate 1091, thereby limiting the contact plate 1090 to only undergo buffer displacement in the clamping direction and reducing the possibility of the contact plate 1090 tilting after being subjected to force. A limiting nut or a limiting retaining ring is provided at the end of the guide rod to prevent the contact plate 1090 from detaching from the fixed back plate 1091.

[0055] In a preferred embodiment, the buffer stroke is 2 to 10 mm, more preferably 3 to 8 mm; the elastic preload of the single-sided buffer clamping plate 109 can be set to 100 to 1000 N, and adjusted according to the wall thickness, material and allowable clamping deformation of the compressor components.

[0056] Therefore, when the two buffer clamping plates 109 first contact the lower side wall of the compressor components, even if the ball nut 103 continues to move a small distance, the contact plate 1090 can absorb the displacement through the elastic buffer in the compression buffer chamber 1092, thereby avoiding a sudden increase in clamping force and providing a synchronous action margin for the upper spiral outer pressure plate 203 to continue to complete the flipping and pressing.

[0057] Preferably, the side of the contact plate 1090 that contacts the compressor components is provided with a reinforcing strip 1093 to increase friction.

[0058] Furthermore, the power connection assembly 30 includes a transmission shaft 303 fixed to the end of the lead screw 101. The transmission shaft 303 extends to the outside of the clamping moving groove 100 and is connected to a second bevel gear 302. The top of the second bevel gear 302 is vertically meshed with a first bevel gear 301. The top of the first bevel gear 301 is fixedly connected to the bottom of the drive gear 209 through a rotating shaft 300, thereby realizing the power transmission to the servo motor 3. Preferably, when the drive gear 209, rotating shaft 300, bevel gear one 301, bevel gear two 302 and other structures are actually installed, a protective shell is provided on their outer side to cover them, thereby providing safety and aesthetics.

[0059] The compressor components in this technical solution refer to cylindrical, annular, arc-shaped, or near-cylindrical metal parts that need to be stably positioned during the welding process, including but not limited to compressor housing, compressor cylinder, upper cover, lower cover, end cover, liquid receiver cylinder, muffler housing, connecting sleeve, pipe joint, flange, mounting bracket, and other metal components that need to be welded and fixed to the compressor housing.

[0060] It is particularly suitable for cylindrical or near-cylindrical compressor parts with an outer diameter of approximately 80–300 mm and a height of approximately 100–400 mm. The above dimensions are only a typical implementation range. By changing the component fixing platform 2, the stroke of the lead screw 101, the diameter of the rotating base ring 206, and the thickness of the spiral outer pressure plate 203, it can also be applied to parts of other sizes.

[0061] The working principle of this invention is as follows: Step 1: Place the compressor component to be welded on the component fixing platform 2; According to the position of the compressor component, adjust the length of the screws 107 located at both ends of the screw barrel 106 by rotating the screw barrel 106. Since one screw 107 is connected to the mounting plate 108 and the other screw 107 is connected to the connecting base plate 104, the connecting base plate 104 and the buffer clamping plate 109 mounted on the connecting base plate 104 are moved to the required initial position by adjusting the screw barrel 106 and the screws 107; According to the position to be welded, adjust the lateral position, longitudinal position and height position of the welding torch by the welding torch position adjustment mechanism.

[0062] Step 2: Start the servo motor 3. The drive shaft of the servo motor 3 drives the connecting shaft 210 to rotate. The connecting shaft 210 drives the drive gear 209 to rotate. The drive gear 209 meshes with the lateral tooth groove 208 on the circumferential outer wall of the rotating base ring 206, thereby driving the rotating base ring 206 to rotate. The rotating base ring 206 maintains rotation under the combined action of the support column 4, the T-shaped slider 31 and the annular T-shaped groove 32.

[0063] Step 3: When the base ring 206 rotates, the tilting drive tooth 207 set on the base ring 206 moves synchronously with the base ring 206. The tilting drive tooth 207 meshes with the tilting ring inner groove 202 on the inner circumferential wall of the tilting ring cylinder 200, so that the tilting ring cylinder 200 rotates around its own axis. During the rotation of the tilting ring cylinder 200, multiple spiral external pressure plates 203 installed on the outer cylinder wall 201 of the tilting ring cylinder rotate with the tilting ring cylinder 200. The contact area between the spiral external pressure plates 203 and the compressor components gradually transitions from a smaller radial dimension area to a larger radial dimension area, gradually reducing the gap between the spiral external pressure plates 203 and the compressor components, and forming a lateral clamping force on the upper side wall area of ​​the compressor components.

[0064] Step 4: While the drive gear 209 rotates, the bottom of the drive gear 209 drives the rotating shaft 300 to rotate. The rotating shaft 300 drives the first bevel gear 301 to rotate. The first bevel gear 301 drives the second bevel gear 302 to rotate through perpendicular meshing with the second bevel gear 302. The second bevel gear 302 drives the transmission shaft 303 to rotate, and drives the lead screw 101 to rotate through the transmission shaft 303. Since the threads of the two lead screws 101 are opposite and are fixedly connected by the connecting block 102, and the two ball nuts 103 are threadedly connected to the two lead screws 101 respectively, when the two lead screws 101 rotate synchronously, the two ball nuts 103 move closer to each other synchronously along the axial direction of the lead screws 101. The ball nuts 103 sequentially drive the support base plate 105, the mounting plate 108, the connecting base plate 104 and the buffer clamping plate 109 to move, so that the two buffer clamping plates 109 on both sides move closer to each other and clamp the lower side wall of the compressor components.

[0065] Step 5: When the two buffer clamping plates 109 contact the lower side wall of the compressor components, as the ball nut 103 continues to move, the contact plate 1090 is acted upon by the compressor components. By compressing the elastic buffer in the buffer cavity 1092 located between the contact plate 1090 and the fixed back plate 1091, the corresponding displacement is absorbed. The guide hole on the fixed back plate 1091 slides with the guide rod on the contact plate 1090, causing the contact plate 1090 to move in the clamping direction. This provides a synchronous action margin for the upper spiral outer pressure plate 203 to continue to complete the flipping and pressing, until the bottom side clamping mechanism 10 and the flipping side pressing mechanism 20 jointly complete the positioning of the compressor components.

[0066] Step Six: After the compressor components are positioned to the required level, the welding device set on one side of the component fixing platform 2 is activated. The welding torch is used to weld the compressor components at the positions to be welded. When using a gas metal arc welding device or a tungsten inert gas welding device, an arc is established between the welding wire or welding electrode and the area to be welded on the compressor components through the welding power source, so that the position to be welded is locally melted to form a molten pool. The shielding gas reduces the possibility of oxidation or porosity caused by contact between oxygen and nitrogen in the air and the molten pool. As the welding torch moves along the welding trajectory, the molten pool cools and solidifies to form a weld. When using a laser welding device, a focused laser beam is used to act on the part to be welded to form a molten pool, and the welding is completed by moving the welding torch or laser welding head along the predetermined weld trajectory.

[0067] Step 7: After welding is completed, adjust the rotation direction of the servo motor 3 to change the rotation direction of the rotating base ring 206. The driving direction of the flip drive tooth column 207 relative to the inner tooth groove 202 of the flip ring cylinder will change accordingly, causing the flip ring cylinder 200 to rotate in the opposite direction. The contact area between the spiral outer pressure plate 203 and the compressor components will move to a smaller radial dimension position, thereby gradually releasing the lateral clamping. At the same time, the power connection assembly 30 drives the lead screw 101 to rotate in the opposite direction, causing the two ball nuts 103 to move away from each other synchronously, and also causing the buffer clamping plates 109 on both sides to move away from each other, thereby releasing the clamping on the lower side wall of the compressor components and completing the release of the compressor components.

[0068] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
