Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and specifically to an integrated welding and grinding device for a glass water tank bracket. Background Art

[0002] With the improvement of people's living standards, the requirements for the quality and aesthetics of sanitary products are also increasing day by day. As an important part of sanitary facilities, the glass water tank of a toilet has gradually gained favor in the market due to its beautiful appearance and strong modern sense.

[0003] A glass water tank usually consists of a glass panel, a bracket, and other functional components. Among them, the bracket plays a key role in supporting and fixing the glass panel, ensuring the stability and reliability of the water tank during use. The manufacturing process of the glass water tank bracket is crucial for ensuring the overall quality of the water tank.

[0004] In the production process of a glass water tank bracket, welding and grinding are key processing procedures. Traditional welding and grinding operations are often carried out separately, and lack effective quality monitoring and automatic repair mechanisms. There are many drawbacks to this traditional method. For example, it is difficult to ensure the uniformity and quality of each welding during manual welding, and lack of welding is likely to occur; if the subsequent grinding process is carried out under the condition of poor welding quality, not only can the effect of a flat surface not be achieved, but rework may also be required due to the discovery of welding defects during the grinding process, resulting in low production efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide an integrated welding and grinding device for a glass water tank bracket, which solves the problem of low efficiency caused by the separate welding and grinding of the existing technology for glass water tank brackets.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An integrated welding and grinding device for a glass water tank bracket, including a workbench, on which an installation frame is slidably connected. A first welding frame and a second welding frame are vertically slidably connected to the installation frame. Welding heads are connected to both the first welding frame and the second welding frame. A welding table is connected to the workbench, and a bracket to be welded is placed on the welding table. There are two groups of welding points on the bracket to be welded. The two welding heads on the first welding frame and the second welding frame are respectively used to weld the two groups of welding points. When the installation frame moves to the upper part of the two groups of welding points, the first welding frame and the second welding frame respectively move downwards and weld the two groups of welding points successively;

[0007] A grinding frame is slidably connected to the workbench, and a grinding disc for grinding the welding points is rotatably connected to the grinding frame. When the welding points are evenly distributed, the fluctuation amplitude of the resistance when the grinding disc moves to the position of the welding points is low. When there is a lack of welding at the welding points, the fluctuation of the resistance when the grinding disc moves to the position of the welding points is high. And when the fluctuation of the resistance when the grinding disc moves to the position of the welding points is high, the mounting frame moves in the reverse direction and welds the welding points again.

[0008] Preferably, two lead screws are symmetrically and rotatably connected to the workbench, and two sliders are symmetrically connected to the mounting frame. Two threaded holes adapted to the two lead screws are respectively formed in the two sliders.

[0009] Preferably, a set of first wedges corresponding to one set of welding points and a set of second wedges corresponding to the other set of welding points are symmetrically arranged on both sides of the welding table. A first sliding rod is connected to the first welding frame, and a second sliding rod is connected to the second welding frame. When the mounting frame moves, the first sliding rod and the second sliding rod respectively slide along the inclined surfaces of the first wedges and the second wedges and move downward, so that the first welding frame and the second welding frame move downward at the two sets of welding points respectively, so that the welding heads weld the welding points.

[0010] Preferably, first springs are connected between the first welding frame and the mounting frame and between the second welding frame and the mounting frame.

[0011] Preferably, the two lead screws are driven by an external motor to rotate at the same speed. First pressure-sensitive switches for controlling the reduction of the rotation speed of the external motor are arranged at the lower parts of the first wedges and the second wedges. After the first sliding rod and the second sliding rod move downward, they respectively abut against the first pressure-sensitive switches.

[0012] Preferably, a sliding seat is connected to the workbench, a connecting rod is slidably connected to the sliding seat, a round rod is connected to the side of the grinding frame, a hole adapted to the round rod is formed in the connecting rod, and a second spring is connected between the round rod and the connecting rod;

[0013] A displacement sensor for detecting the round rod is arranged in the connecting rod. When the grinding disc moves to the welding point, the round rod slides towards the connecting rod. When the grinding disc moves from the non-lack-of-welding part of the welding point to the lack-of-welding part, the round rod slides away from the connecting rod.

[0014] Preferably, an electromagnetic driver for driving the connecting rod to slide is arranged in the sliding seat. When the grinding disc moves to the welding point, the load of the electromagnetic driver increases, so that the current increases.

[0015] Preferably, a lifting seat is connected to the lower part of the first pressure-sensitive switch. The load of the electromagnetic driver first increases and then decreases. When the round rod slides slightly away from the connecting rod, the lifting seat moves downward.

[0016] Preferably, a vertical seat is connected to the workbench. A rectangular piston rod is slidably connected in the vertical seat. The end of the rectangular piston rod is connected with a rectangular piston plate. An air pipe is communicated between the sliding cavity in the vertical seat that cooperates with the rectangular piston plate and the sliding cavity of the lifting seat. One end of the connecting rod away from the grinding frame is connected with an electric telescopic rod. The load of the electromagnetic driver first increases and then decreases. When the round rod slides slightly away from the connecting rod, the electric telescopic rod extends;

[0017] After the grinding disc moves past two sets of welding points, the connecting rod slides back toward the vertical seat. When the electric telescopic rod is in the extended state, the reset of the connecting rod can cause the electric telescopic rod to push the rectangular piston rod to slide, so that the lifting seat moves downward.

[0018] Preferably, a baffle is connected to the side of the vertical seat away from the rectangular piston rod. A third spring is connected between the baffle and the rectangular piston plate;

[0019] A second pressure-sensitive switch for controlling the reverse rotation of the lead screw is arranged on the baffle. When the rectangular piston plate slides, it can abut against the second pressure-sensitive switch.

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

[0021] 1. In the present invention, by controlling the sliding of the mounting rack on the workbench, the mounting rack slides successively over the upper parts of two sets of welding points. The first welding rack and the second welding rack descend successively when passing through the two sets of welding points. When the first welding rack or the second welding rack descends, the control system controls the corresponding welding head to start and weld the two sets of welding points one by one. After the first welding rack or the second welding rack passes the corresponding welding point, it moves upward. At this time, the control system controls the corresponding welding head to stop operating. When the mounting rack drives the first welding rack and the second welding rack to pass through the two sets of welding points and move to the end of one end of its stroke, it stops moving. Subsequently, the grinding disc moves to grind the welding points, making the surface of the welded bracket smooth, thus facilitating the subsequent installation of the glass panel. When the grinding disc grinds the welding points, if the welding points are uniform and there is no lack of welding, the resistance fluctuation of the grinding rack when moving above the welding points is low and tends to be uniform. However, when there is a lack of welding at the welding points and the lack of welding part is large, when the grinding rack moves to the lack of welding part of the welding point, its moving resistance will suddenly decrease, that is, at this time, the resistance fluctuation of the grinding rack when moving above the welding point is large, indicating poor welding quality. Therefore, the grinding rack resets, and the mounting rack moves in the reverse direction, repeating the above welding steps to re-weld the welding points and ensure the welding quality. During this process, the reverse movement of the mounting rack completes the welding. And after the mounting rack moves to the other end of its stroke, the grinding rack moves again to grind the welding points to ensure the welding quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figures 1-8 , this embodiment provides a technical solution: an integrated welding and grinding device for a glass water tank bracket, including a workbench 1, a mounting frame 3 is slidably connected to the workbench 1, a first welding frame 33 and a second welding frame 35 are vertically slidably connected to the mounting frame 3, welding heads 37 are connected to both the first welding frame 33 and the second welding frame 35, a welding table 11 is connected to the workbench 1, a bracket 2 to be welded is placed on the welding table 11, there are two sets of welding points on the bracket 2 to be welded, and the two welding heads 37 on the first welding frame 33 and the second welding frame 35 are respectively used to weld the two sets of welding points. When the mounting frame 3 moves to the upper part of the two sets of welding points, the first welding frame 33 and the second welding frame 35 respectively move downwards and successively weld the two sets of welding points; a grinding frame 42 is slidably connected to the workbench 1, a grinding disc 43 for grinding the welding points is rotatably connected to the grinding frame 42. When the welding points are uniform, the resistance fluctuation amplitude of the grinding disc 43 moving at the welding point part is low. When there is a lack of welding at the welding point, the resistance fluctuation of the grinding disc 43 moving at the welding point part is high. And when the resistance fluctuation of the grinding disc 43 moving at the welding point part is high, the mounting frame 3 moves in the reverse direction and welds the welding point again.

[0033] The welding table 11 is provided with a groove that matches the bracket 2 to be welded. Each part of the bracket 2 to be welded is placed in the groove on the welding table 11. At this time, the two welding parts of the bracket 2 to be welded can be in contact with each other. Control the mounting frame 3 to slide on the workbench 1. The mounting frame 3 slides over the upper parts of the two welding points in sequence. The first welding frame 33 and the second welding frame 35 descend in sequence when passing through the two welding points. When the first welding frame 33 or the second welding frame 35 descends, the control system controls the corresponding welding head 37 to start and weld the two welding points one by one. After the first welding frame 33 or the second welding frame 35 passes through the corresponding welding point, it moves upward. At this time, the control system controls the corresponding welding head 37 to stop running. When the mounting frame 3 drives the first welding frame 33 and the second welding frame 35 to pass through the two welding points and move to the end of one end of its stroke, it stops moving. Subsequently, the grinding disc 43 moves to grind the welding points, making the surface of the welded bracket smooth, so as to facilitate the subsequent installation of the glass panel 21;

[0034] When the grinding disc 43 grinds the welding points, if the welding points are uniform and there is no lack of welding, the resistance fluctuation of the grinding frame 42 when moving above the welding points is low and tends to be uniform. When there is a lack of welding at the welding points and the lack of welding part is large, when the grinding frame 42 moves to the lack of welding part of the welding point, its moving resistance will suddenly decrease. That is, at this time, the resistance fluctuation of the grinding frame 42 when moving above the welding points is large, indicating that the welding quality is poor. Thus, the grinding frame 42 resets, and the mounting frame 3 moves in the reverse direction, repeating the above welding steps to re-weld the welding points to ensure the welding quality. During this process, the reverse movement of the mounting frame 3 completes the welding. After the mounting frame 3 moves to the other end of its stroke, the grinding frame 42 moves again to grind the welding points to ensure the welding quality;

[0035] In addition, the control system monitors the remaining amount of the welding material in real time. The specific monitoring technology is the existing technology. If there is a lack of welding due to insufficient welding material, an alarm will be issued. After the welding material is replenished, the device will repeat the above actions for welding and grinding.

[0036] Two lead screws 31 are symmetrically and rotatably connected to the workbench 1. Two sliders 32 are symmetrically connected to the mounting frame 3. Two threaded holes that match the two lead screws 31 are respectively provided in the two sliders 32.

[0037] The two lead screws 31 rotate synchronously and at a constant speed to drive the two sliders 32 to slide synchronously, so that the mounting frame 3 moves on the workbench 1.

[0038] On both sides of the soldering table 11, a set of first wedges 341 corresponding to one set of welding points and a set of second wedges 361 corresponding to the other set of welding points are symmetrically arranged. A first sliding rod 34 is connected to the first welding frame 33, and a second sliding rod 36 is connected to the second welding frame 35. When the mounting frame 3 moves, the first sliding rod 34 and the second sliding rod 36 slide along the inclined surfaces of the first wedge 341 and the second wedge 361 respectively and move downward, so that the first welding frame 33 and the second welding frame 35 move downward at the two sets of welding points respectively, so that the welding head 37 welds the welding points.

[0039] As the mounting frame 3 continues to move, the first sliding rod 34 and the second sliding rod 36 slide along the inclined surfaces of the first wedge 341 and the second wedge 361 respectively. Due to the guiding action of the inclined surfaces, the first welding frame 33 and the second welding frame 35 will move downward at the two sets of welding points respectively, so that the corresponding welding heads 37 approach the welding points and start to weld the welding points.

[0040] A first spring 38 is connected between the first welding frame 33 and the mounting frame 3 and between the second welding frame 35 and the mounting frame 3.

[0041] The setting of the first spring 38 enables both the first welding frame 33 and the second welding frame 35 to be supported, so that they will not move downward relative to the mounting frame 3 when the first sliding rod 34 and the second sliding rod 36 do not move to the first wedge 341 or the second wedge 361. At the same time, after the first sliding rod 34 and the second sliding rod 36 move past the first wedge 341 or the second wedge 361, the spring can push up the corresponding first welding frame 33 and second welding frame 35, so that they are away from the bracket 2 to be welded, and the welding head 37 can be closed in time;

[0042] It should be noted again that both the first wedge 341 and the second wedge 361 are trapezoidal in reverse. When the first sliding rod 34 or the second sliding rod 36 moves to the lowest point, the welding head 37 can just be located above the welding point. At this time, the welding head 37 starts, so that the welding effect of the welding point is not affected by the moving factor of the welding head 37.

[0043] Both of the two lead screws 31 are driven by an external motor to rotate at the same speed. First pressure-sensitive switches 39 for controlling the reduction of the rotation speed of the external motor are arranged at the lower parts of the first wedge 341 and the second wedge 361. After the first sliding rod 34 and the second sliding rod 36 move downward, they both abut against the first pressure-sensitive switch 39.

[0044] After the first sliding rod 34 and the second sliding rod 36 move downward, they will abut against the first pressure-sensitive switch 39 at the lower parts of the first wedge block 341 and the second wedge block 361. The first pressure-sensitive switch 39 will control the reduction of the external motor speed, so that the welding process can be more stable, avoiding the decline of welding quality caused by too fast welding speed. At the same time, when the mounting bracket 3 does not pass through the welding point, the rotation speed of the lead screw 31 is relatively fast, so as to ensure that the mounting bracket 3 can quickly move to the welding point position and ensure the welding efficiency.

[0045] A sliding seat 4 is connected to the workbench 1. A connecting rod 41 is slidably connected to the sliding seat 4. A round rod 44 is connected to the side of the grinding frame 42. A hole matching the round rod 44 is formed in the connecting rod 41, and a second spring 45 is connected between the round rod 44 and the connecting rod 41; A displacement sensor for detecting the displacement of the round rod 44 is arranged in the connecting rod 41. When the grinding disc 43 moves to the welding point, the round rod 44 slides towards the connecting rod 41. When the grinding disc 43 moves from the non-weld-deficient part of the welding point to the weld-deficient part, the round rod 44 slides away from the connecting rod 41.

[0046] A displacement sensor is arranged in the connecting rod 41 to detect the displacement of the round rod 44. When the grinding disc 43 just contacts the welding point, the welding point forms a resistance to the movement of the grinding disc 43. At this time, the round rod 44 slides towards the connecting rod 41, providing a stroke space for the subsequent sliding of the round rod 44 away from the connecting rod 41. When the grinding disc 43 moves from the non-weld-deficient part of the welding point to the weld-deficient part, since there is no solder at the weld-deficient part to block the movement of the grinding disc 43, the second spring 45 pushes the round rod 44 to slide away from the connecting rod 41, and this displacement change is detected by the displacement sensor, thereby judging that the welding point is weld-deficient.

[0047] An electromagnetic driver for driving the sliding of the connecting rod 41 is arranged in the sliding seat 4. When the grinding disc 43 moves to the welding point, the load of the electromagnetic driver increases, so the current increases.

[0048] The electromagnetic driver in the sliding seat 4 on the workbench 1 drives the connecting rod 41 to slide. The connecting rod 41 slides on the sliding seat 4. Since the round rod 44 on the side of the grinding frame 42 cooperates with the connecting rod 41 and is connected with a second spring 45, the grinding frame 42 can move along with the sliding of the connecting rod 41. When the grinding disc 43 moves to the welding point, the welding point causes resistance to the movement of the connecting rod 41. At this time, the load of the electromagnetic driver increases and the current increases. When the control system detects the increase in current, it indicates that the grinding disc 43 has moved to the welding point position to perform the grinding operation. At this time, the displacement sensor will be started under the control of the control system, reducing the interference factors during the movement process.

[0049] The lower part of the first pressure-sensitive switch 39 is connected to a lifting seat 57. When the load of the electromagnetic driver first increases and then decreases, and the round rod 44 slides a small amount away from the connecting rod 41, the lifting seat 57 moves downward.

[0050] When the grinding disc 43 moves to the lack-welding part, the resistance received by the connecting rod 41 also decreases. Therefore, the load of the electromagnetic driver can be reduced at this time. Combined with the detection of the displacement sensor, the detection of whether there is lack of welding at the welding point during the grinding process is more accurate.

[0051] A vertical seat 5 is connected to the workbench 1. A rectangular piston rod 51 is slidably connected inside the vertical seat 5. The end of the rectangular piston rod 51 is connected to a rectangular piston plate 52. A trachea 56 is communicated between the sliding cavity in the vertical seat 5 that cooperates with the rectangular piston plate 52 and the sliding cavity of the lifting seat 57. One end of the connecting rod 41 away from the grinding frame 42 is connected to an electric telescopic rod 46. When the load of the electromagnetic driver first increases and then decreases, and the round rod 44 slides a small amount away from the connecting rod 41, the electric telescopic rod 46 extends; after the grinding disc 43 moves past two groups of welding points, the connecting rod 41 slides and resets towards the vertical seat 5. When the electric telescopic rod 46 is in the extended state, the reset of the connecting rod 41 can make the electric telescopic rod 46 push the rectangular piston rod 51 to slide, so that the lifting seat 57 moves downward.

[0052] In the above actions, when the load of the electromagnetic driver first increases and then decreases, and the round rod 44 slides a small amount away from the connecting rod 41, it indicates that there is a lack-welding part at the welding point at this time. After the control system receives the above signal, it will control the electric telescopic rod 46 to extend. Thus, after the connecting rod 41 resets, the extended electric telescopic rod 46 can push the rectangular piston rod 51 to slide. At this time, the rectangular piston rod 51 drives the rectangular piston plate 52 to slide synchronously. The sliding of the rectangular piston plate 52 generates negative pressure, so that the air in the sliding cavity of the lifting seat 57 is extracted through the trachea 56. Therefore, at this time, the lifting seat 57 drives the first pressure-sensitive switch 39 to move downward. Subsequently, the external motor drives the mounting frame 3 to move in the reverse direction to perform the repair welding operation on the welding point. At this time, the first pressure-sensitive switch 39 is in the downward movement state. Therefore, the downward movement of the first slide bar 34 and the second slide bar 36 will not collide with the first pressure-sensitive switch 39. Furthermore, the moving speed of the mounting frame 3 during the repair welding process will not be reduced, so that there will not be too much welding material at the welding point. On the one hand, it reduces the consumption of welding materials, and on the other hand, it is convenient for subsequent grinding;

[0053] During the process of the control system controlling the grinding frame 42 to move again, when the current changes of the displacement sensor and the electromagnetic driver are transmitted to the control system, the control system no longer controls the electric telescopic rod 46 to extend, because the welded point after repair welding will not be flat, thus eliminating the influence of this factor.

[0054] On one side of the upright seat 5 away from the rectangular piston rod 51, a baffle 53 is connected. A third spring 54 is connected between the baffle 53 and the rectangular piston plate 52. A second pressure-sensitive switch 55 for controlling the reverse rotation of the lead screw 31 is provided on the baffle 53, and the rectangular piston plate 52 can abut against the second pressure-sensitive switch 55 when sliding.

[0055] When the control system controls the movement of the connecting rod 41 and grinds the welded joint after repair welding, the electric telescopic rod 46 shortens. After the second grinding, the welded joint can basically meet the required quality requirements. At this time, the welded bracket is removed, and then the bracket 2 to be welded is placed for welding.

[0056] In addition, when the electric telescopic rod 46 extends and the rectangular piston plate 52 is pushed, the rectangular piston plate 52 can abut against the second pressure-sensitive switch 55. At this time, without manual operation, the second pressure-sensitive switch 55 will control the lead screw 31 to reverse to perform the repair welding action. Moreover, when the connecting rod 41 moves after repair welding to grind the welded joint, the third spring 54 can push the rectangular piston plate 52 to reset, so that the first pressure-sensitive switch 39 resets, thereby enabling the mounting frame 3 to still move to the welded joint at a reduced speed when welding the next bracket 2 to be welded.

[0057] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
