Description

Technical Field

[0001] This application relates to the field of welding processing technology, specifically to a high-precision plasma welding device for processing textile machinery frames. Background Technology

[0002] The beat-up mechanism is a common component of textile machinery. Its function is to forcefully and evenly push the weft yarn introduced into the shed towards the weft end, so that it interweaves with the warp yarn to form a tight and flat fabric. Common beat-up mechanisms usually include a reed foot, a rocker shaft, a reed seat, and a steel reed. One end of the reed foot is fixed to the rocker shaft through an open sleeve, and the other end (upper part) is used to install the reed seat, which converts the thrust from the cam or connecting rod into a reciprocating oscillation around the center of the rocker shaft.

[0003] Typically, a reed base includes the main structure (stiffening plates and web plates), the rocker arm connection (mounting flange), and the reed mounting surface (top platform). When machining large reed bases, to facilitate demolding, the rocker arm connection and the main structure are machined separately. Then, the machined rocker arm connection flange is welded to the main frame. To make the connection between the rocker arm connection and the main structure more stable, plasma welding is usually used (because plasma welding has better penetration, it can make the weld position between the rocker arm connection and the main structure more secure). However, the common welding method in the existing technology requires welding one side of the rocker arm connection to the main structure first, then flipping or reversing the rocker arm connection to the main structure, and then welding the other side. This welding method is not very efficient in actual processing. Summary of the Invention

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the prior art, this application provides a high-precision plasma welding device for textile machinery frame processing, which can effectively solve the problem that the common welding method of reed seat feet in the prior art requires welding the rocker shaft connection part to one side of the main structure first, and then flipping or turning the rocker shaft connection part to the main structure over, and then welding the other side. This welding method has low welding efficiency in actual processing.

[0006] Technical solution

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] This application provides a high-precision plasma welding device for textile machinery frame processing, including a frame, and further including: a divider fixedly installed inside the frame, a dividing plate rotatably installed above the divider, and a plurality of fixing components for fixing workpieces are provided on the dividing plate. When the fixing components rotate with the dividing plate, they drive the workpieces to rotate.

[0009] The mounting frame is located on the outside of the machine frame, and the middle part is respectively equipped with a first plasma welding gun and a second plasma welding gun. The first plasma welding gun and the second plasma welding gun respectively weld the front and back sides of the workpiece.

[0010] A fixed platform is fixedly installed on the frame below the dividing plate. The fixed platform is used to drive the fixed component and the workpiece above it to rotate when the dividing plate rotates, so as to adjust the welding surface.

[0011] Furthermore, a central gear is provided on the outer side of the fixed platform. The central gear is used to drive the fixed assembly to rotate when the dividing disk rotates. The fixed assembly includes a rotating sleeve rotatably mounted on the dividing disk. A fixed seat for fixing the workpiece is fixedly installed above the rotating sleeve. A planetary gear that meshes with the central gear is provided on the outer side of the rotating sleeve.

[0012] Furthermore, a sliding member is installed in the middle of the rotating sleeve, and a lifting plate is fixedly installed above the sliding member. The lifting plate is used to press the workpiece onto the fixed seat, and a limiting groove is provided on the side of the sliding member for sliding up and down with the inner wall of the rotating sleeve.

[0013] Furthermore, a connecting rod is rotatably mounted below the sliding member, a rotating wheel is provided on the side of the connecting rod, and an annular guide rail is provided on the outer side of the fixed platform for driving the connecting rod to move up and down.

[0014] Furthermore, the dividing disk has a first station, a second station, a third station, and a fourth station, which are equally spaced on the dividing disk. The first plasma welding gun and the second plasma welding gun are respectively installed on the sides of the second station and the third station. When the planetary gear rotates from the second station to the third station, the planetary gear rotates at a certain angle. The annular guide rail is used to make the corresponding sliding parts located at the lowest point when the workpiece moves to the second station and the third station.

[0015] Furthermore, a base plate is fixedly installed on the dividing plate, the base plate is supported below the fixed seat, the fixed seat has a fixed groove with an opening on one side in the middle, and the lifting plate is lifted and installed directly above the middle of the fixed groove.

[0016] Furthermore, a slide rail is fixedly installed above the mounting bracket, and several clamping members are slidably installed on the slide rail. The clamping members are driven to be installed on the slide rail above, and a telescopic member is provided in the middle of the clamping member. The clamping member is used to carry the workpiece to a designated position and remove the welded workpiece from the dividing plate.

[0017] Furthermore, the middle part of the lifting plate is provided with a connecting groove for connecting with the sliding component, and a bolt is threadedly installed on the upper part of the lifting plate, and the lower part of the bolt is threadedly connected to the sliding component.

[0018] Furthermore, mounting grooves are provided on both sides of the lower end face of the lifting plate, and a bent plate is fixedly installed inside the mounting groove. The middle part of the bent plate is inclined in the direction away from the opening of the fixed groove. The lower part of the bent plate extends out of the mounting groove, and the lower end of the bent plate is provided with a plane that contacts the inner wall of the workpiece. When the lifting plate moves downward, the lower end face of the bent plate contacts the inner wall of the workpiece and causes the workpiece to tend to move away from the opening of the fixed groove.

[0019] Furthermore, the lower end face of the bent plate is provided with an anti-slip rubber pad.

[0020] Beneficial effects

[0021] The technical solution provided in this application has the following advantages compared with the known public technology:

[0022] This application uses multiple fixing components above the dividing plate to fix the position of the workpiece. When the fixing components rotate with the dividing plate, they will cause the workpiece to rotate as well. When the workpiece moves to different stations, different welding surfaces will face the outside of the dividing plate, which makes it easier for the first and second plasma welding guns installed on the outside of the dividing plate to move up, down, left, and right, so as to achieve more precise welding processing of the workpiece. In addition, since one workpiece is being welded on the front side at the second station, another workpiece will be welded on the reverse side at the third station, which can quickly complete the continuous welding processing of multiple workpieces.

[0023] This application uses a sliding component installed inside a rotating sleeve and an annular guide rail below the fixed platform. When the workpiece moves from the first station to the second station, the annular guide rail drives the sliding component to move downward by limiting the horizontal height of the rotating wheel. When the workpiece moves from the third station to the fourth station, the annular guide rail drives the sliding component to move upward by limiting the horizontal height of the rotating wheel. This achieves the fixing and loosening of the workpiece, facilitating the loading and unloading of the workpiece. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] The present application will be further described below with reference to embodiments.

[0040] like Figure 1 - Figure 10 As shown, this embodiment proposes a high-precision plasma welding device for textile machinery frame processing, including a frame 1, in which a divider 11 is fixedly installed, and a dividing disk 3 is rotatably installed on the top. The divider 11 is used to drive the dividing disk 3 to rotate. The dividing disk 3 is provided with a plurality of fixing components for fixing workpieces 4. When the fixing components follow the dividing disk 3 to rotate, they drive the workpieces 4 to rotate.

[0041] Mounting frame 2 is located outside the frame 1. It is equipped with a first plasma welding gun 21 and a second plasma welding gun 22. The first plasma welding gun 21 and the second plasma welding gun 22 weld the front and back sides of the workpiece, respectively. The dividing plate 3 is formed with a first station, a second station, a third station and a fourth station. The first station, the second station, the third station and the fourth station correspond to the workpiece 4 processing states of loading, front welding, back welding and unloading, respectively. The first station, the second station, the third station and the fourth station are equally spaced on the dividing plate 3. The first plasma welding gun 21 and the second plasma welding gun 22 are respectively installed on the side of the second station and the third station.

[0042] A slide rail 23 is fixedly installed above the mounting frame 2. Several clamping members 24 are slidably installed on the slide rail 23. The clamping members 24 are driven to be installed on the slide rail 23. A telescopic member is provided in the middle of the clamping member 24. The clamping member 24 is used to carry the workpiece 4 to a designated position and remove the welded workpiece 4 from the dividing plate 3. When the rocker shaft connection part of the workpiece 4 is in the second position, the main structure of the workpiece 4 can be clamped and moved above the rocker shaft connection part of the workpiece 4 in the second position by one of the clamping members 24. Then, the first plasma welding gun 21 can be controlled to weld the rocker shaft connection part of the workpiece 4 to the main structure. The clamping member 24 can be a common robotic gripper in the prior art. Each clamping member 24 is driven by an independent drive device (such as a servo motor and lead screw, or a linear module) to move on the slide rail 23. Each clamping member 24 is provided with a telescopic member (such as a cylinder or electric push rod) in the middle. These are common implementation methods in the prior art, and their related principles will not be described in detail here.

[0043] A fixed platform 37 is fixedly installed on the frame 1 below the dividing disk 3. A plane bearing 372 is provided on the fixed platform 37. The fixed platform 37 is rotatably connected to the dividing disk 3 through the plane bearing 372, which can support the lower part of the dividing disk 3. The fixed platform 37 is used to drive the fixed assembly and the workpiece 4 above it to rotate when the dividing disk 3 rotates, so as to adjust the welding surface. A central gear 36 is provided on the outer side of the fixed platform 37. The central gear 36 is used to drive the fixed assembly to rotate when the dividing disk 3 rotates. The fixed assembly includes a rotating sleeve 34 rotatably installed on the dividing disk 3. A fixed base 32 for fixing the workpiece 4 is fixedly installed on the top. A planetary gear 341 that meshes with the central gear 36 is provided on the outer side of the rotating sleeve 34. When the planetary gear 341 rotates from the second station (front welding station) to the third station (reverse welding station), the planetary gear 341 rotates exactly 180 degrees, thereby causing the workpiece 4 to rotate 180 degrees, so that the front side after welding faces the inside of the dividing plate 3 and the reverse side to be welded faces the second plasma welding gun 22, and the two welding surfaces are welded separately. In addition, the separate welding station can also reduce the heat accumulation on the welding end face.

[0044] In this embodiment, by setting multiple fixing components above the dividing plate 3, the position of the workpiece 4 can be fixed. When the fixing components rotate with the dividing plate 3, the fixing components will drive the workpiece 4 to rotate, so that when the workpiece 4 moves to different workstations, different welding surfaces will face the outside of the dividing plate 3, which makes it easier for the first plasma welding gun 21 and the second plasma welding gun 22 installed on the outside of the dividing plate 3 to move up, down, left and right, so as to achieve more precise welding processing of the workpiece 4. In addition, since one workpiece 4 is welded on the front side at the second workstation, another workpiece 4 will be welded on the reverse side at the third workstation, the continuous welding processing of multiple workpieces 4 can be completed quickly.

[0045] The first plasma welding gun 21 and the second plasma welding gun 22 both adopt technologies commonly used in the prior art, and their principles will not be described in detail here. The mounting frame 2 is provided with a drive structure for moving the first plasma welding gun 21 and the second plasma welding gun 22 up, down, left and right. Both adopt drive methods commonly used in the prior art, which are unrelated to the core solution of this application, and their related principles will not be described in detail here.

[0046] In the above technical solution, by setting a central gear 36 and a planetary gear 341 on the fixed platform 37 and the rotating sleeve 34 respectively, the dividing disk 3 can not only switch the workstation of the workpiece 4 during rotation, but also switch the welding surface of the workpiece 4 simultaneously (during the switch from the second workstation to the third workstation). However, since the welding operation of the workpiece 4 is performed at the second and third workstations, the workpiece 4 needs to have a certain stability during welding, that is, the workpiece 4 and the fixed seat 32 need to remain relatively stationary. In order to achieve this purpose, in this embodiment, a sliding member 35 is installed in the middle of the rotating sleeve 34. A lifting plate 33 is fixedly installed above the workpiece 4, which is used to press the workpiece 4 onto the fixed seat 32. The side of the sliding member 35 is provided with a limiting groove 3501 that slides up and down with the inner wall of the rotating sleeve 34. A protrusion is provided on the inner wall of the rotating sleeve 34 to insert into the limiting groove 3501. The protrusion is used to drive the sliding member 35 to rotate synchronously with the rotating sleeve 34. A base plate 31 is fixedly installed on the dividing plate 3, which is supported below the fixed seat 32. A fixing groove with an opening on one side is formed in the middle of the fixed seat 32. The lifting plate 33 is lifted and installed directly above the middle of the fixing groove. A connecting rod 351 is rotatably installed below the sliding member 35. The side of the connecting rod 351 A rotating wheel 352 is provided, and an annular guide rail 371 is provided on the outer side of the fixed platform 37 to drive the connecting rod 351 to move up and down. When the planetary gear 341 rotates from the second station to the third station, the planetary gear 341 rotates 180 degrees. The annular guide rail 371 is used to keep the corresponding sliding member 35 at the lowest point when the workpiece 4 moves to the second and third stations. When the workpiece 4 moves from the first station to the second station, the annular guide rail 371 drives the sliding member 35 to gradually move downward by limiting the horizontal height of the rotating wheel 352. When the workpiece 4 moves from the third station to the fourth station, the annular guide rail 371 limits the lifting of the rotating wheel. The horizontal height of 352 drives the sliding member 35 to gradually move upward, so as to fix and release the workpiece 4, which facilitates the loading and unloading of the workpiece 4. The recessed part of the annular guide rail 371 is set below the corresponding second and third stations, which is used to drive the sliding member 35 to move downward at these two stations where the workpiece 4 needs to be stabilized for welding, so that the lifting plate 33 presses the workpiece 4 tightly on the fixed seat 32, which can reduce the adjustment range of the first plasma welding gun 21 and the second plasma welding gun 22 in the initial stage of welding. At the first station (loading) and the fourth station (unloading), the annular guide rail 371 moves upward horizontally, so that the lifting plate 33 is raised.

[0047] It should be noted that the circular guide rail 371 includes a high section and a low section. The low section is located below the second and third workstations, and the high section is located below the fourth and first workstations. The section from the first workstation to the second workstation is a gradually downward section (the sliding member 35 moves down, which has the effect of fixing the workpiece 4), and the section from the third workstation to the fourth workstation is a gradually upward section (the sliding member 35 moves up, which has the effect of releasing the workpiece 4).

[0048] As workpiece 4 moves from the first station to the second station, the annular guide rail 371 will drive the sliding member 35 downwards. However, it takes a certain distance for the lifting plate 33 above the sliding member 35 to be fully pressed against the inner wall of workpiece 4. During this process, the dividing disc 3 has already started to rotate. At this time, workpiece 4 may experience relative displacement with the fixed seat 32 under the action of centrifugal force. The relative displacement between workpiece 4 and fixed seat 32 will affect the positioning of subsequent welding processing (the welding position needs to be adjusted back and forth). In order to make the positioning of subsequent welding processing more convenient, this embodiment has a lifting plate 33 The middle part of the lifting plate 33 is provided with a connecting groove 3301 for connecting with the sliding member 35. A bolt is threaded on the upper part of the lifting plate 33, and the lower part of the bolt is threaded to the sliding member 35. Both sides of the lower end face of the lifting plate 33 are provided with mounting grooves 3302. A bent plate 331 is fixedly installed inside the mounting groove 3302. The middle part of the bent plate 331 is inclined in the direction away from the opening of the fixed groove. The lower part of the bent plate 331 extends out of the mounting groove 3302. The lower end of the bent plate 331 is provided with a plane that contacts the inner wall of the workpiece 4. When the lifting plate 33 moves downward, the lower end face of the bent plate 331 contacts the workpiece 4. The inner wall contacts the workpiece 4, causing it to tend to move away from the opening of the fixed slot. When the lifting plate 33 moves downward, the bending plate 331 will first contact the inner wall of the rocker shaft connection of the workpiece 4 and generate friction (at this time, the bending plate 331 is equivalent to giving the workpiece 4 a pre-fixed force). Then, as the lifting plate 33 continues to move downward, the bending plate 331 can bend. When the bending plate 331 bends, since the bottom of the bending plate 331 is tilted away from the opening of the fixed slot, the bending plate 331 will generate a force that causes the inner wall of the rocker shaft connection to move away from the fixed opening. The movement on one side can compensate for the position of the rocker shaft connection (part of the workpiece 4), so that one end of the rocker shaft connection is always against the inner wall of the fixed groove. This allows the rocker shaft connection of the workpiece 4 to be more stably fixed inside the fixed groove, which facilitates the positioning of subsequent welding processing and the docking of the other part of the workpiece 4 (main structure). The lower end face of the bending plate 331 is provided with an anti-slip pad, which can increase the friction between the bottom of the bending plate 331 and the inner wall of the workpiece 4, so that the friction between the bending plate 331 and the inner wall of the workpiece 4 is sufficient to overcome the tendency of the workpiece 4 to slide inside the fixed seat 32.

[0049] Overall working state description: In the initial state, the dividing disc 3 stops rotating, and the first station is in the loading position. The rocker shaft connection part of the workpiece 4 to be welded is taken from the outside with manual assistance or mechanical means and placed horizontally into the opening fixing slot of the fixing seat 32 of the first station. Then, the divider 11 drives the dividing disc 3 to rotate 90 degrees clockwise, bringing the fixing assembly with the rocker shaft connection part into the second station (front welding station). During this process, when the fixing assembly passes the starting section of the annular guide rail 371 on the fixing table 37 corresponding to the first to second station, the rotating wheel 352 rolls along the descending surface of the annular guide rail 371, driving the sliding part 35 and the lifting plate 33 to move down through the connecting rod 351, pressing the workpiece 4. Inside the fixed slot, the main structure of workpiece 4 is moved and placed above the rocker shaft connection of workpiece 4 by one of the clamping members 24. Then, the first plasma welding gun 21 is driven to weld the two parts of workpiece 4. After welding, the dividing plate 3 rotates 90 degrees again, bringing workpiece 4 into the third station (reverse welding station). During the rotation from the second station to the third station, the planetary gear 341 rotates exactly 180 degrees under the continuous meshing transmission with the stationary central gear 36, thereby causing the rotating sleeve 34, the fixed seat 32 and the clamped workpiece 4 to rotate 180 degrees together, so that the welded front side faces the inside of the dividing plate 3 and the unwelded reverse side faces the outside. At this time, the lifting plate 33 is still kept in a clamped state under the action of the annular guide rail 371. After reaching the third station, the second plasma welding gun 22 is started to weld the reverse side of the workpiece. After the reverse welding is completed, the dividing plate 3 continues to rotate 90 degrees, bringing the workpiece 4 into the fourth station (unloading station); before entering the fourth station, the rotating wheel 352 passes through the upper section of the annular guide rail 371, and the sliding part 35 moves up synchronously, driving the lifting plate 33 to lift and release the workpiece 4; at the fourth station, another set of clamping parts 24 moves over, takes the welded workpiece 4 from the fixed seat 32 and transfers it to the unloading area.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this application.
