Description

Technical Field

[0001] This invention relates to the field of actuator processing equipment technology, and more specifically, to a multi-station welding apparatus for cylindrical actuator cylinder bodies. Background Technology

[0002] An actuator is a crucial component used in mechanical or automated systems, primarily for performing motion or control operations. Depending on the specific application, actuators vary in shape and structure. For applications such as conveyor belt systems or steering systems, actuators are often cylindrical, while for linear drive structures, such as assembly lines, pneumatic or hydraulic systems, actuators are typically rectangular.

[0003] The actuator cylinder body is the main body of the actuator, and the cylinder body contains components such as pistons, seals and other structural parts. Some structural parts, such as limiting parts, connecting parts and fixing parts, are welded to the actuator cylinder body. The welding method for actuator cylinder bodies is mostly plasma arc welding, which achieves fast and efficient welding results without contacting the object.

[0004] Currently, there are many methods using plasma arc welding on the market, including direct welding by connecting a welding torch to a plasma arc welding machine and welding with multiple clamping devices connected to the plasma arc welding machine and welding torches on a fixture device. As the fixture rotates or moves, a cyclic welding effect is achieved. Although the cyclic welding method can achieve the purpose of sequential welding, the actuator cylinder body needs to be fixed by the clamping device. The rotation of the fixture only changes the position of the actuator cylinder body, but the welding angle of the actuator cylinder body itself cannot be changed. Even if the clamping device is rotatable, it still needs to be adjusted manually or by control equipment. On the one hand, the process is cumbersome, and on the other hand, it only sorts and welds multiple actuator cylinder bodies, and does not change the independence between welding and transmission, resulting in no significant improvement in welding efficiency.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a multi-station welding device for cylindrical actuator cylinder bodies. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a multi-station welding device for cylindrical actuator cylinder bodies.

A fixed seat is connected to the inner wall of a ring-shaped limiting seat via a support rod. A shaft is rotatably connected to the fixed seat, passing through the rotating seat and connecting to the gear seat. One of the two fixed seats is equipped with a motor that drives the shaft. Gear a has an integral through-structure clamping sleeve at its center. One end of the clamping sleeve extends into the rotating seat and is rotatably connected to it. The other end of the clamping sleeve is nested with a connecting sleeve that is rotatably connected to gear a and is movable and limited by an annular groove on the outer wall of the adjusting seat. A transmission box is located on the side of the clamping sleeve and is used to clamp and control the clamping block inside the clamping sleeve.

[0008] Preferably, the number of welding components is the same as that of gears a. The welding component includes a sleeve rod that is connected to the connecting sleeves on the two gears a respectively by curved rods at both ends, an adjusting tube with a hollow structure that runs through the sleeve rod from top to bottom, and a welding end that is fitted inside the adjusting tube from the bottom. Power connectors that provide power transmission to the welding end are provided on both sides of the top of the adjusting tube. The welding end and the adjusting tube adopt an adjustable structure with a snap and hole. The power line of the welding end is connected to the power connector through the inside of the adjusting tube.

[0009] Preferably, a power box is provided on the outer end face of the power supply base, and an arc-shaped slide is provided on the inner end face of the power supply base. Conductive plates are provided on both sides of the slide to contact the power connector and to connect to the power interface of the power box through a line passing through the interior of the power supply base.

[0010] Preferably, the rotating seat includes an annular sleeve connected to the arcuate groove of the base and a disc-shaped seat that limits rotation within the annular sleeve. The disc-shaped seat has a through hole at its center for the shaft to pass through, and a groove is provided on the side of the through hole, which is circumferentially distributed around the through hole and fits into the clamping sleeve. The groove and the clamping sleeve are connected in a limiting rotational manner.

[0011] Preferably, the connecting sleeve is nested on the clamping sleeve and is limited and connected to the annular groove on gear a by a limiting ring provided on the fitting end of the connecting sleeve. The top of the connecting sleeve is provided with an arc-shaped slider connected by a support rod and fitted into the annular groove; wherein, the connecting sleeve and the clamping sleeve are connected by a limiting rotation.

[0012] Preferably, there are two clamping blocks, and adjusting rods that pass through the clamping sleeve and the transmission box are connected to the two clamping blocks in sequence. The transmission box is equipped with a transmission assembly for moving and controlling the two adjusting rods, and the outside of the transmission box is equipped with a control seat for driving the transmission assembly.

[0013] Preferably, the transmission assembly includes a transmission seat a and a transmission seat b with a double-belt connection structure and connected by a transmission belt, a gear b connected to the transmission seat a by a transmission belt and meshing with a toothed groove on an adjusting rod, a gear c connected to the transmission seat b by a transmission belt, and a gear d meshing with the toothed groove on the transmission seat b.

[0014] Preferably, the control base includes an adjustment disc disposed on the transmission box and an adjustment component that passes through the center of the adjustment disc and is connected to the transmission base a.

[0015] Preferably, the adjustment assembly includes two fixed disks, a rotating shaft a rotatably connected between the two fixed disks, a rotating shaft b connected to the inner wall of the two fixed disks and passing through the center of the adjustment disk and connected to the transmission seat a, and an L-shaped rocker arm connected to the rotating shaft a and capable of engaging with a limiting hole by rotation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This welding device, through the design of a planetary transmission mechanism, can drive the clamped actuator cylinder and the welding part to rotate synchronously via planetary gears. While changing positions, the welding angle is also adjusted. Based on this transmission, the device is also equipped with a welding component that rotates synchronously with the planetary gears, ensuring that the welding component always corresponds to the welding position. In conjunction with the synchronous rotation of the actuator cylinder and the welding part driven by the planetary gears, the welding position and angle are automatically adjusted during the cyclic welding process. This effectively achieves the overall integration of welding position and angle adjustment, reduces the process steps, and further improves welding efficiency.

[0018] 2. The welding components of this welding device adopt an intermittent start-stop control mode, dividing the welding device into a welding zone and a dwell zone. After the welding components, the actuator cylinder and the welded parts are loaded, enter the welding zone. Utilizing the conductivity of metal, the power supply at the welding end is connected to the power box. After welding, the actuator cylinder and the welded parts enter the dwell zone, and the power supply at the welding end is disconnected from the power box. This enables the welding components to achieve intermittent start-stop automated control, thereby effectively achieving energy saving. Attached Figure Description

[0050] like Figure 1-16As shown, the present invention provides a multi-station welding device for cylindrical actuator cylinder bodies, including two bases 1 with arc grooves, a limiting seat 4, a rotating seat 5 and an adjusting seat 6 arranged sequentially in the arc grooves, a power supply seat 3 located on the side of the base 1 and connected to the rotating seat 5 by multiple sets of support rods in an arc structure, and a welding assembly 2 connected between the two bases 1.

[0051] The adjusting seat 6 has an overall ring structure and is provided with a toothed seat 601 and at least two gears a602 that are respectively limited to the inner wall of the adjusting seat 6 and the toothed seat 601. The two toothed seats 601 are connected by a connecting rod 9. At the center of each of the two limiting seats 4, there is a fixed seat 401 connected to the inner wall of the ring-shaped limiting seat 4 by a support rod. A shaft is rotatably connected to the fixed seat 401, which passes through the rotating seat 5 and the toothed seat 601. One of the two fixed seats 401 is provided with a motor 8 that drives the shaft.

[0052] Furthermore, such as Figure 5 and Figure 6 As shown, the overall structure of the adjustment seat 6 adopts a planetary transmission mechanism. The sun tooth is the gear seat 601, the planetary tooth is the gear a602, and the outer gear sleeve is the adjustment seat 6 with tooth grooves arranged inside. The gear seat 601 is driven by the motor 8, and at the same time, it cooperates with the connecting rod 9 to achieve the effect of overall transmission of the gear seats 601 on the two bases 1.

[0053] Meanwhile, a clamping sleeve 10 with an integral through structure is provided at the center of the gear a602. One end of the clamping sleeve 10 extends into the rotating seat 5 and is rotatably connected to the rotating seat 5. The other end of the clamping sleeve 10 is nested with a connecting sleeve 7 that is rotatably connected to the gear a602 and is moved and limited by an annular groove 603 provided on the outer wall of the adjusting seat 6. A transmission box 11 is provided on the side end of the clamping sleeve 10 for clamping and controlling the clamping block 12 provided in the clamping sleeve 10.

[0054] Specifically, such as Figure 6 , Figure 7 and Figure 10 As shown, the gear a602 is driven by the rotation of the gear seat 601. According to the characteristics of the planetary transmission mechanism, the gear a602 will revolve between the adjusting seat 6 and the gear seat 601, that is, move along a circular trajectory. At the same time, the gear a602 will also rotate on its own axis through meshing transmission. By setting a clamping mechanism on the gear a602 to provide limit for the actuator cylinder and the welded parts, after the actuator cylinder and the welded parts are clamped, they can follow the gear a602 to revolve and rotate. On the one hand, multiple actuator cylinders can be cyclically welded for loading and unloading operations. On the other hand, during the welding process, the actuator cylinder can be welded at different angles by adjusting the rotation.

[0055] To facilitate welding of the clamped actuator cylinder body, such as Figure 4 and Figure 8 As shown, the number of welding components 2 is the same as that of gears a602. Welding components 2 include a sleeve rod 201 that is connected to the connecting sleeves 7 on the two gears a602 by curved rods at both ends, an adjusting tube 202 that has a hollow structure and runs through the sleeve rod 201 from top to bottom, and a welding end 204 that is fitted into the adjusting tube 202 from the bottom. Power connectors 203 that provide power transmission to the welding end 204 are provided on both sides of the top of the adjusting tube 202.

[0056] Furthermore, the welding assembly 2 adopts a rod-connected structure, which is connected to the connecting sleeves 7 on the two bases 1 respectively. In order to facilitate the longitudinal position adjustment of the welding end 204, the welding end 204 and the adjusting tube 202 adopt an interlocking telescopic structure. At the same time, the welding end 204 and the adjusting tube 202 adopt a buckle and hole adjustable structure. The power line of the welding end 204 is connected to the power connector 203 through the inside of the adjusting tube 202. In order to enhance the adaptability of the welding assembly 2, the curved rod and the sleeve rod 201 can adopt an integrated through structure, so that the sleeve rod 201 can slide laterally on the curved rod. At the same time, it can be used with the buckle and hole structure for limit control. For the lateral adjustment structure of the sleeve rod 201, the adjusting tube 202 adopts a top and bottom two-section design, which is the best. Meanwhile, the welding end 204 is the end used for plasma arc welding. Since it does not need to directly contact the welding part, the friction caused by the direct contact between the welding end 204 and the welding part is also avoided.

[0057] As further explained above, the sleeve 201 has a hollow internal structure, and the connection between the welded end 204 and the adjusting tube 202 is adjustable via a snap-fit ​​or hole mechanism. Figure 9 As shown, the spring buckles on both sides of the welding end 204 can be matched with the corresponding sets of holes on both sides of the adjusting tube 202 to achieve the purpose of adjusting the longitudinal position of the welding end 204. In order to improve the adjustment speed, a manually adjustable telescopic rod can be set inside the adjusting tube 202. The adjustable rod part will extend through the adjusting tube 202 to the outside for easy manual adjustment. The wiring part of the welding end 204 will pass through the wire groove set in the inner wall of the adjusting tube 202 and connect to the top of the adjusting tube 202, and connect to the power connector 203. Since the welding method is a circular structure with circular motion, to avoid wire entanglement, it is best to use a manual adjustment mechanism for the telescopic adjustment of the welding end 204. If an electric adjustment method is used, the number of turns should be limited if the wiring allows, and a reset operation is required.

[0058] Meanwhile, the start / stop control of the welding end 204 adopts an intermittent control method, such as... Figure 1, Figure 2 , Figure 8 and Figure 12 As shown, the specific circuit connection is that the positive and negative terminals of the power supply of the welding end 204 are connected to the power connectors 203 on both sides of the top of the regulating tube 202 through the line, so that the two power connectors 203 serve as the contact ends for the positive and negative terminals of the welding end 204 respectively. The power connectors 203 adopt a metal ball structure, and the selected metal may include copper, iron and other metals with good conductivity. At the same time, in order to reduce the friction effect, the ball structure of the power connector 203 can also be replaced with a metal ball structure.

[0059] To achieve the aforementioned intermittent welding effect, such as Figure 1 , Figure 2 , Figure 3 and Figure 12 As shown, a power box 301 is provided on the outer end face of the power supply base 3, and an arc-shaped slide 302 is provided on the inner end face of the power supply base 3. Conductive pieces 303 are provided on both sides of the slide 302, which can contact the power connector 203 and are connected to the power interface of the power box 301 through the inside of the power supply base 3 via a line.

[0060] Specifically, for the welding device, one side is the welding area, and the other side is the loading, unloading, and clamping control area, also known as the dwell area. When gear a602 revolves to one side of the power supply base 3, the welding end 204 will be activated to perform the welding operation. The power supply adopts a contact power supply method. After the welding component 2 enters the welding area, the regulating pipe 202 will enter the arc-shaped slide 302 set on the power supply base 3. Since the conductive plates 303 on both sides of the slide 302 are connected to the positive and negative terminals of the power box 301 through lines, the conductive plates... 303 and the power connector 203 are made of the same material, and the positions of the positive and negative conductive plates 303 correspond to the positions of the positive and negative power connectors 203. After the power connector 203 contacts the conductive plate 303, a series closed circuit is formed for the welding end 204. The welding end 204 will be in the open state. Welding is performed on the actuator cylinder and welding parts in the synchronous rotation state through the welding end 204. After the power connector 203 passes through the slide 302, the circuit will be automatically disconnected and the welding end 204 will be closed.

[0061] It should be noted that the arc-shaped power supply base 3 corresponds to the trajectory of the gear a602's revolution.

[0062] To improve the overall stability of gear A602 during operation, such as Figure 4 and Figure 6As shown, the rotating seat 5 includes an annular sleeve 501 connected to the arc groove of the base 1 and a disc seat 502 that limits the rotation within the annular sleeve 501. The disc seat 502 has a through hole 503 at its center for the shaft to pass through. The side of the through hole 503 has a groove 504 that is circumferentially distributed around the through hole 503 and fits into the clamping sleeve 10.

[0063] Further explanation, such as Figure 6 As shown, since the clamping sleeve 10 is involved in bearing and clamping the actuator cylinder and welded parts, the gear a602 itself is limited by its structure. Although it is an integral structure with the clamping sleeve 10, the clamping sleeve 10 is cylindrical and much longer than the thickness of the gear a602. It provides bearing by extending to the outside of the gear a602, which can lead to an imbalance of force on the gear a602. This can easily cause the gear a602 or the clamping sleeve 10 to deform.

[0064] To solve the above problems, the extended end of the clamping sleeve 10 is connected to the corresponding slot 504 on the disc-shaped base 502. The force generated by the revolution of gear a602 drives the disc-shaped base 502 to rotate adaptively. Since gear a602 also rotates in conjunction with the clamping sleeve 10, the slot 504 and the clamping sleeve 10 are connected in a limited rotational manner. Figure 6 and Figure 10 As shown, the clamping sleeve 10 and the slot 504 are respectively provided with annular buckles and slots with a rotating connection structure. The disc seat 502 and the gear a602 form an adaptive rotation form. The disc seat 502 can effectively enhance the load-bearing effect of the clamping sleeve 10 and improve the stability of the clamping sleeve 10 when bearing load.

[0065] To ensure that welding component 2 can revolve with gear a602, and to guarantee the correspondence and accuracy of the welding position, such as... Figure 4 and Figure 8 As shown, the connecting sleeve 7 is nested on the clamping sleeve 10, and is limited and connected to the annular groove opened on the gear a602 by the limiting ring buckle provided on the fitting end of the connecting sleeve 7. The top of the connecting sleeve 7 is provided with an arc-shaped slider 701 connected by a support rod and fitted into the annular groove 603.

[0066] Specifically, the connecting sleeve 7 has a cylindrical structure and serves as the connector for the welding assembly 2. The connecting sleeve 7 essentially drives the welding assembly 2 to revolve around the gear a602, while also accommodating the rotation of the gear a602. Furthermore, it must not affect the clamping of the clamping sleeve 10 on the actuator cylinder and the welding components. Therefore, the connecting sleeve 7 adopts a nested, rotatable connection structure, as detailed below. Figure 6As shown, the connecting sleeve 7 is directly rotatably connected to the annular groove opened on the gear a602 through the limiting ring buckle. At the same time, the fitting part of the connecting sleeve 7 and the clamping sleeve 10 also adopts the limiting rotation connection, which is the same buckle and groove limiting connection form as the connection structure of the clamping sleeve 10 and the disc seat 502.

[0067] To achieve the effect of limiting the rotation of the connecting sleeve 7, an annular groove 603 is provided on the outer wall of the adjusting seat 6. The connecting sleeve 7 moves with the gear a602 through the engagement of the slider 701 with the annular groove 603, and is not affected by the rotation of the gear a602. The overall connection structure of the connecting sleeve 7 and the clamping sleeve 10 is essentially the same as the connection structure of the rotating seat 5 and the clamping sleeve 10. According to the above, the welding assembly 2 can coordinate with the rotation of the gear a602 to make the welding end 204 of the welding assembly 2 always correspond to the welding part of the actuator cylinder and the welded part in the rotating state. Through the revolution of the gear a602, the actuator cylinder and the welded part can be welded in an integral and comprehensive manner.

[0068] It should be noted that since the power supply of the arc-shaped power supply base 3 and the welding end 204 is intermittent, it is necessary to ensure that the number of rotations of gear a602 is at least one revolution during the entire power supply period from the start of the welding assembly 2 entering the slide 302 to the end. If the number of revolutions is increased, it must be increased in whole numbers. Based on the specific number of revolutions, the size and transmission ratio between the tooth grooves on the inner wall of the gear base 601, gear a602 and adjusting base 6 should be adjusted accordingly.

[0069] In order to achieve clamping and fixing of the actuator cylinder and welded parts, such as Figure 10 , Figure 11 , Figure 13 and Figure 14 As shown, there are two clamping blocks 12. The two clamping blocks 12 are connected to adjusting rods 1201 that pass through the clamping sleeve 10 and the transmission box 11 in sequence. The transmission box 11 is equipped with a transmission assembly 13 for moving and controlling the two adjusting rods 1201. The transmission box 11 is equipped with a control seat 14 for driving the transmission assembly 13.

[0070] The aforementioned transmission assembly 13 includes a transmission seat a1301 and a transmission seat b1302 that are connected by a transmission belt in a double-belt connection structure; a gear b1303 that is connected to the transmission seat a1301 by a transmission belt and meshes with the toothed groove on the adjusting rod 1201; a gear c1304 that is connected to the transmission seat b1302 by a transmission belt; and a gear d1305 that meshes with the toothed groove on the transmission seat b1302.

[0071] Specifically, such as Figure 14As shown, the clamping block 12 is driven by a combination of belt and meshing transmission to control the clamping of the clamping block 12.

[0072] Specifically, such as 15 and Figure 16 As shown, the control base 14 includes an adjustment disk 1401 disposed on the transmission box 11 and an adjustment component 1402 passing through the center of the adjustment disk 1401 and connected to the transmission base a1301. The adjustment disk 1401 is provided with a limiting hole 1403 that is circumferentially distributed with the center of the adjustment disk 1401 as the center and limits the adjustment component 1402.

[0073] The adjustment assembly 1402 includes two fixed disks, a rotating shaft a rotatably connected between the two fixed disks, a rotating shaft b connected to the inner wall of the two fixed disks and passing through the center of the adjustment disk 1401 and connected to the transmission seat a1301, and an L-shaped rocker connected to the rotating shaft a and capable of engaging with the limiting hole 1403 by rotation.

[0074] To achieve convenient control and avoid the problem of tangled wires, such as Figure 16 As shown, the L-shaped rocker arm of the adjustment component 1402 has a structure that can be radially flipped, so that the adjustment component 1402 can act as a crank to manually drive the transmission component 13, and can also act as a limiting mechanism to limit the position of the clamping block 12.

[0075] In summary, when this welding device achieves automated welding through a planetary transmission mechanism, the rotation direction can be forward or reverse. The difference lies in the timing of welding, but the final effect is the same.

[0076] At the same time, this welding device can be used for excessively long actuator cylinders, such as... Figure 2As shown, loading and unloading can be performed through the gaps between multiple sets of support rods and clamping sleeves 10 between the fixed seat 401 and the limiting seat 4. For actuator cylinders of suitable length, loading and unloading can be performed through the gap between the two bases 1. By default, at least one of the two clamping sleeves 10 is directly below the connecting sleeve 7. The actuator cylinder and the welding part are placed in the two clamping sleeves 10 respectively. After adjusting the position and aligning the welding position with the welding end 204, the locking of the control seat 14 is released, and the L-shaped rocker arm is rocked to drive the transmission box. The transmission component 13 within 11 is used to limit and fix the actuator cylinder and welded parts. During the adjustment process, the accuracy of the welding position of both must also be ensured. After clamping, the L-shaped rocker arm can be flipped to insert the end of the rod into the corresponding limiting hole 1403 on the adjustment plate 1401. By adjusting the longitudinal position of the welding end 204, it is aligned with the welding point of the actuator cylinder and welded parts. The motor 8 is started. The motor 8 drives the gear seat 601 at the center position of the two adjustment seats 6 to rotate simultaneously through the shaft and connecting rod 9. The specific welding includes the following:

[0077] If motor 8 rotates towards the power supply base 3, gear a602 drives the actuator cylinder and welded parts to rotate in the opposite direction to the rotation of motor 8. This rotation includes the revolution and rotation of gear a602. Gear a602 will drive the connecting sleeve 7 and its welding component 2 to revolve together, so that the welding end 204 is always in contact with the welding position. After the welding component 2 enters the slide 302 of the power supply base 3, the electrical connection is achieved through the conductivity of metal, and the welding end 204 will start. In this state, as gear a602 continues to rotate, it drives the actuator cylinder and welded parts to rotate, coordinating with the corresponding positions. The welding end 204 effectively achieves the overall welding of the actuator cylinder and the welded parts. When the welding assembly 2 moves to the outside of the power supply base 3, the power connection of the welding end 204 will be disconnected. At this time, the welding is completed and it is directly above the adjustment base 6. Another clamping sleeve 10 driven by gear a602 will be directly below the adjustment base 6. The loading process is carried out according to the aforementioned loading process. The welding process is the same as the aforementioned process. After the clamping sleeve 10 is welded, the previously welded actuator cylinder and welded parts will rotate to the initial loading position of the adjustment base 6. After the locking of the control base 14 is released, the parts are unloaded and the new welded parts and actuator cylinder are installed.

[0078] It should be noted that this welding equipment can be used in conjunction with a loading and unloading robotic arm to improve welding efficiency. The welding component 2 is manually adjustable. This method is suitable for welding actuator cylinders that are cylindrical in shape or for applications limited to cylindrical circular openings. For cylindrical bodies with other components at the edges, the system can adaptively control the extension and retraction of the welding component 2, which has an automated adjustment structure. Based on the shape of the actuator cylinder, the system sets the welding trajectory, the extension and retraction time of the welding component 2, the intermittent start / stop control of the motor 8, and the rotation speed of the motor 8, thereby achieving an adaptive welding effect. This method requires the motor 8 to be used in both forward and reverse directions to avoid affecting the wiring.
