Description

Technical Field

[0001] The invention relates to a cutting and welding integrated machine, in particular to a sofa bracket cutting and welding machine applied in the technical field of welding and cutting equipment. Background Art

[0002] In order to improve the production efficiency of the sofa bracket, during the welding process of the sofa bracket, the metal bracket parts will have some defects, and the metal bracket parts will have some size differences. Therefore, in order to improve the welding effect of the sofa bracket, it is necessary to use cutting tools to repair the metal bracket parts, and then weld them to connect the various bracket parts.

[0003] The specification of Chinese invention patent CN202210902848.8 discloses "A steel strip cutting and welding integrated machine". By turning the joystick, the transmission rod can be driven to rotate through the No. 1 pulley and the belt, so that the conversion disk can be rotated to achieve the purpose of converting the cutting and welding heads, thereby avoiding the time-consuming and laborious disassembly and installation of the cutting head and the welding head, saving time and workers' energy. In addition, since this function is set on the joystick that can realize the welding and cutting function, the worker only needs the right hand to complete the operation, which is more convenient for the worker's operation and saves the time of training workers to learn and master the equipment.

[0004] Although the existing integrated cutting and welding machines can switch between cutting and welding, the switching methods are mostly to perform height dislocation and rotational position exchange. The above invention is the rotational exchange of the cutting structure and the welding structure. This switching method requires a relatively large switching space, which is not convenient for inserting in the sofa bracket, affecting the welding operation of the sofa bracket. At the same time, the non-working cutting structure and welding structure lack protection and are easily bumped by the bracket, and the structure used for switching between the cutting structure and the welding structure is more susceptible to bumps, affecting the overall stability of the integrated machine. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the non-working cutting structure and welding structure and the structure used for switching are easily bumped, which affects the overall stability of the integrated machine.

[0006] In order to solve the above problems, the present invention provides a sofa support cutting and welding machine, comprising an integrated box fixedly mounted on the movable end of a manipulator, wherein a track arm is movably connected inside the integrated box, and a welding module and a cutting module are slidably connected at the left and right ends of the track arm, respectively, the welding module and the cutting module correspond to the two ends inside the integrated box, and the combined width of one of the welding module and the cutting module and the track arm corresponds to the internal width of the integrated box;

[0007] The left and right ends of the integrated box are fixedly connected with fixed tubes, and a closed block door is hinged at one end of the fixed tube close to the inlet and outlet of the integrated box. The two groups of closed block doors correspond to the left and right ends of the inlet and outlet of the integrated box respectively, and a straight rib is fixedly connected between the closed block door and the outer wall of the integrated box. A door closing screw is inserted into the interior of the fixed tube, one end of the door closing screw is fixedly connected to the middle part of the closed block door, and the other end of the door closing screw extends from the end of the fixed tube away from the closed block door, and the other end of the door closing screw is fixedly connected to a tail gasket, and the tail gaskets correspond to the tails of the welding module and the cutting module.

[0008] In the above-mentioned sofa support cutting and welding integrated machine, by selectively retracting the welding module and the cutting module into the integrated box, the switching use and protection of the welding module and the cutting module can be achieved, which is convenient for interlaced work in the sofa support.

[0009] As a further improvement of the present application, the middle portion of the straight rib is bent in an Ω shape, and the straight rib is made of spring steel material. The straight rib made of spring steel material has good elasticity, which facilitates bending of the middle portion of the straight rib.

[0010] As a further improvement of the present application, a wire gap is opened on the outside of one end of the fixed tube close to the inlet and outlet of the integrated box, and the door closing wire passes through the wire gap, and the door closing wire is made of wear-resistant steel wire material. When the closing block door is pulled closed by the door closing wire, the taut door closing wire can pass through the wire gap, so that the fixed tube, the door closing wire and the closing block door are in a triangular state, effectively improving the closing and stability effect of the closing block door.

[0011] As a further improvement of the present application, the outer surfaces of the welding module and the cutting module are fixedly connected with interference wedges, and the middle part of the inner wall of the integrated box is fixedly connected with interference wedge slopes, and the interference wedges are in contact with the interference wedge slopes. After the welding module and the cutting module are retracted into the integrated box, the contact between the interference wedges and the interference wedge slopes is utilized to tighten the track arm in the integrated box, thereby effectively improving the stability of the track arm and further improving the stability of the use of the welding module and the cutting module retained outside the track arm.

[0012] As another improvement of the present application, the contact wedge slope is inclined with one end close to the inlet and outlet of the integrated box as the starting point, and the contact wedge block is made of elastic rubber material. The contact wedge block gradually extends along the inclined surface of the contact wedge slope, thereby gradually improving the contact and extrusion effect between the contact wedge block and the contact wedge slope. The contact wedge block made of elastic rubber material has good deformation effect, which further improves the contact and extrusion effect between the contact wedge block and the contact wedge slope.

[0013] As another improvement supplement of the present application, a door groove is opened in the middle of the track arm. The door groove is arranged in a triangular shape and is clamped with the closed block door. The clamping connection between the door groove and the closed block door is utilized to limit the closed block door from further rotating into the closed block door, thereby effectively improving the impact resistance of the closed block door.

[0014] As another improvement supplement to the present application, the outer surface of the closed block door is arranged in a triangular shape, and the outer surface of the closed block door is fixedly wrapped with an anti-collision pad, the anti-collision pad is made of rubber material, and the triangular outer surface of the closed block door is arranged to deflect the impact received by the closed block door, thereby effectively improving the protection capability of the closed block door, and at the same time the anti-collision pad effectively improves the impact resistance of the closed block door.

[0015] As another improvement of the present application, a bolt groove is opened in the middle part of the door groove, and a movable bolt is inserted into the inside of the closed block door, and the movable bolt is inserted into the bolt groove. When the closed block door is closed, the movable bolt is inserted into the bolt groove to realize automatic locking of the closed block door, thereby effectively improving the closing stability of the closed block door, and at the same time relieving the pressure of the welding module and the cutting module on the track arm on the tail pad, thereby effectively protecting the sliding effect of the welding module and the cutting module on the track arm.

[0016] To summarize, the present invention realizes the switching use of the cutting function and the welding function of the all-in-one machine by switching and sliding the welding module and the cutting module on the track arm. At the same time, the integrated box provides shielding protection for the retracted welding module and the cutting module, and squeezes the tail pad during the retraction of the welding module and the cutting module, and uses the closing wire to pull the closing block door to close the inlet and outlet of the integrated box, thereby further effectively improving the shielding protection effect of the integrated box on the internal welding module and the cutting module. At the same time, the retracted welding module and the cutting module cooperate with the track arm to plug the middle part of the integrated box, and the closing block door cooperates with the track arm to plug the inlet and outlet of the integrated box, thereby effectively improving the stability of the shielding protection of the welding module and the cutting module, and effectively improving the stability of the track arm, thereby providing a stable use environment for the welding module and the cutting module retained outside the track arm.

[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figures 1 to 6 The invention shows a sofa support cutting and welding machine, comprising an integrated box 1 fixedly mounted on the movable end of the manipulator, wherein the integrated box 1 is movably connected to a track arm 101, and the left and right ends of the track arm 101 are respectively slidably connected to a welding module 102 and a cutting module 103, wherein the welding module 102 and the cutting module 103 correspond to the two ends inside the integrated box 1, and the combined width of one of the welding module 102 and the cutting module 103 and the track arm 101 corresponds to the internal width of the integrated box 1, and the outer surfaces of the welding module 102 and the cutting module 103 are both fixedly connected to a resisting wedge 3, and the middle part of the inner wall of the integrated box 1 is fixedly connected to a resisting wedge slope 301, and the resisting wedge 3 is in contact with the resisting wedge slope 301, and the welding module 102 and the cutting module 103 are respectively connected to the inner ends of the integrated box 1. After the cutting module 103 is retracted into the integrated box 1, the contact between the friction wedge block 3 and the friction wedge slope 301 is utilized to plug the track arm 101 in the integrated box 1, thereby effectively improving the stability of the track arm 101, and further improving the use stability of the welding module 102 and the cutting module 103 retained outside the track arm 101. The friction wedge slope 301 is inclinedly arranged with one end close to the inlet and outlet of the integrated box 1 as the starting point. The friction wedge block 3 is made of elastic rubber material. The friction wedge block 3 gradually extends along the inclined surface of the friction wedge slope 301, thereby gradually improving the friction and extrusion effect between the friction wedge block 3 and the friction wedge slope 301. The friction wedge block 3 made of elastic rubber material has good deformation effect, which further improves the friction and extrusion effect between the friction wedge block 3 and the friction wedge slope 301.

[0031] When using the integrated machine to weld the sofa bracket, the cutting module 103 is first used to cut the defects on the metal bracket parts. Then, when the parts need to be welded, the welding module 102 slides out of the integrated box 1 along the track arm 101, and the track arm 101 moves horizontally to the end of the integrated box 1 close to the welding module 102, leaving space at the end of the integrated box 1 close to the cutting module 103, and the cutting module 103 retracts into the integrated box 1 along the track arm 101 to realize the switching of the cutting module 103 and the welding module 102, and fully utilizes the internal space of the integrated box 1 to minimize the size of the integrated box 1, so as to facilitate the insertion of the cutting and welding integrated machine in the sofa bracket. After the cutting module 103 retracts into the integrated box 1, the interference wedge 3 on the cutting module 103 conflicts with the interference wedge slope 301, that is, the cutting module 103 plugs the track arm 101 tightly into the integrated box 1, thereby effectively improving the stability of the track arm 101 after switching, and facilitating the welding module 102 on the track arm 101 to perform welding operations.

[0032] Figures 5 to 7 As shown, both left and right ends of the integrated box 1 are fixedly connected with a fixed tube 2, and one end of the fixed tube 2 close to the inlet and outlet of the integrated box 1 is hinged with a closed block door 201, and the two groups of closed block doors 201 correspond to the left and right ends of the inlet and outlet of the integrated box 1 respectively, and a straight rib 202 is fixedly connected between the closed block door 201 and the outer wall of the integrated box 1, and the middle part of the straight rib 202 is bent in an Ω shape, and the straight rib 202 is made of spring steel material. The straight rib 202 made of spring steel material has good elasticity, which is convenient for the middle part of the straight rib 202 to bend, and a closing wire 203 is inserted into the interior of the fixed tube 2, and one end of the closing wire 203 is fixedly connected to the middle part of the closing block door 201, and the other end of the closing wire 203 is fixedly connected to the middle part of the closing block door 201. The end extends from the end of the fixed tube 2 away from the closing block door 201, and the other end of the door closing wire 203 is fixedly connected to a tail pad 204, and the tail pad 204 corresponds to the tails of the welding module 102 and the cutting module 103. A wire notch 205 is opened on the outside of the end of the fixed tube 2 close to the inlet and outlet of the integrated box 1, and the door closing wire 203 passes through the wire notch 205. The door closing wire 203 is made of wear-resistant steel wire material. When the closing block door 201 is pulled closed by the door closing wire 203, the taut door closing wire 203 can pass through the wire notch 205, so that the fixed tube 2, the door closing wire 203 and the closing block door 201 are in a triangular state, which effectively improves the closing and stability effect of the closing block door 201.

[0033] When the cutting module 103 is retracted into the integrated box 1 along the track arm 101, the tail of the cutting module 103 applies pressure to the tail gasket 204, thereby using the tail gasket 204 to pull the door closing wire 203, and the closing block door 201 is pulled by the door closing wire 203 to close the inlet and outlet of the integrated box 1, that is, the integrated box 1 is close to one end of the cutting module 103. The original closing block door 201 is kept flush with the inlet and outlet of the integrated box 1 by the elastic force of the straight ribs 202. When the closing block door 201 is pulled by the door closing wire 203, the middle part of the straight ribs 202 is bent, so that the closing block door 201 closes the inlet and outlet of the integrated box 1. When the closing block door 201 closes the inlet and outlet of the integrated box 1, the closing block door 201 also contacts the track arm 101, further improving the fixing effect of the track arm 101.

[0034] The second implementation method:

[0035] Figure 3 and Figures 6 to 8 As shown, a door slot 302 is provided in the middle of the track arm 101, and the door slot 302 is arranged in a triangular shape, and the door slot 302 is engaged with the closed block door 201. The engagement between the door slot 302 and the closed block door 201 limits the closed block door 201 from further rotating into the closed block door 201, thereby effectively improving the impact resistance of the closed block door 201. The outer surface of the closed block door 201 is arranged in a triangular shape, and the outer surface of the closed block door 201 is fixedly wrapped with an anti-collision pad 303, and the anti-collision pad 303 is made of rubber material. The triangular outer surface of the closed block door 201 is arranged to deflect the impact received by the closed block door 201, thereby effectively improving the protection capability of the closed block door 201, and at the same time, the anti-collision pad 303 effectively improves the impact resistance of the closed block door 201.

[0036] When the closed block door 201 closes the inlet and outlet of the integrated box 1, the closed block door 201 is inserted into the door groove 302, thereby preventing the closed block door 201 from further penetrating into the integrated box 1, and the outer surface of the closed block door 201 is triangular in shape. When the closed block door 201 is impacted, the impact force is deflected by the triangular inclined surface of the closed block door 201, and the deformation buffering capacity of the anti-collision pad 303 is utilized, thereby effectively improving the impact resistance of the closed block door 201.

[0037] Figures 7 to 9As shown, a bolt groove 304 is provided in the middle of the door groove 302, and a movable bolt 305 is inserted into the interior of the closed block door 201, and the movable bolt 305 is inserted into the bolt groove 304. When the closed block door 201 is closed, the movable bolt 305 is inserted into the bolt groove 304 to realize automatic locking of the closed block door 201, effectively improving the closing stability of the closed block door 201, and at the same time relieving the pressure of the welding module 102 and the cutting module 103 on the track arm 101 on the tail pad 204, effectively protecting the sliding effect of the welding module 102 and the cutting module 103 on the track arm 101;

[0038] When the closing block door 201 is engaged with the door slot 302, the movable bolt 305 on the closing block door 201 is inserted into the bolt slot 304, thereby achieving a state fixing effect of the closing block door 201. At this time, the cutting module 103 on the track arm 101 no longer needs to apply pressure to the tail pad 204, and the drive of the track arm 101 to the cutting module 103 is stopped, which effectively avoids the long-term force application of the track arm 101 affecting its own stability and effectively improves the service life of the track arm 101.

[0039] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
