DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] The utility model provides a welding piece surface quality detection device, comprising a workbench 1. Figure 1 As shown, the workbench 1 is disc-shaped and placed horizontally. The bottom of the workbench 1 is fixedly equipped with support legs 2 for support. The center position of the top of the workbench 1 is rotatably connected to the rotating block 5. Four horizontal rotating rods 6 are welded on the rotating block 5, and the four rotating rods 6 are distributed in a cross shape along the rotation center of the rotating block 5 and are arranged radially along the rotation circumference of the rotating block 5. The ends of the four rotating rods 6 away from the rotating block 5 are rotatably connected to the placement plate 8 through the rotating shaft, and the welding parts are placed in the placement plate 8. The rotating shaft is fixedly connected to the placement plate 8 and rotatably connected to the rotating rod 6 to ensure that the placement plate 8 can rotate in a vertical plane to approach or move away from the workbench 1. A second stepper motor 7 is bolted to each rotating rod 6, and the output shaft of the second stepper motor 7 is coaxially fixedly connected to the rotating shaft on the rotating rod 6. When the placement plate 8 needs to rotate in a vertical plane and unload the welding parts, it is used to drive the rotating shaft to rotate; when the placement plate 8 does not need to rotate, it is used to ensure that the placement plate 8 is always placed horizontally.

[0025] like Figure 2 As shown, the first stepper motor 4 is fixed by bolts at the bottom of the workbench 1, and the output shaft of the first stepper motor 4 rotates vertically upward coaxially through the workbench 1 and is fixedly connected to the rotating block 5 to drive the rotating block 5 to rotate.

[0026] like Figure 1 As shown, the placement plate 8 is a rectangular plate and a notch is cut at the end away from the rotating block 5. An annular baffle 3 is welded on the side circumferential surface of the workbench 1, and the end of the placement plate 8 where the notch is located is in sliding contact with the annular baffle 3. It is ensured that when the placement plate 8 rotates with the rotating rod 6, the welded parts will not be thrown out of the placement plate 8 under the action of centrifugal force.

[0027] The baffle plate 3 is radially cut with a first opening, a second opening, a third opening and a fourth opening. The first opening, the second opening, the third opening and the fourth opening are uniformly distributed along the circumference of the baffle plate 3 in sequence. The first opening, the second opening, the third opening and the fourth opening all match the notch on each placement plate 8, and the welded parts can slide in or out through the first opening, the second opening, the third opening and the fourth opening. A first clamping plate 11 is limitedly slidably matched in each placement plate 8, and each first clamping plate 11 slides close to or away from the notch on the placement plate 8. Two first springs 10 are placed in each placement plate 8, and the two first springs 10 are arranged along the sliding direction of the first clamping plate 11, one end of each first spring 10 is fixedly connected to the first clamping plate 11, and the other end of each first spring 10 is fixedly connected to the placement plate 8. Used for buffering and resetting of the first clamping plate 11.

[0028] A first collection box 12 and a second collection box 13 are fixedly placed below the workbench 1. The first collection box 12 is used to collect welded parts that have passed the inspection, and the second collection box 13 is used to collect welded parts that have failed the inspection. The first collection box 12 is located below the second opening of the baffle 3, and the second collection box 13 is located below the third opening of the baffle 3. Figure 2 As shown, two through slots 9 are provided on the workbench 1, and both through slots 9 penetrate the workbench from top to bottom, and the ends away from the center of the workbench 1 both pass through the workbench 1. Each through slot 9 matches with the placement tray 8, so that the placement tray 8 can rotate and pass through the through slot 9. One of the two through slots 9 corresponds to and communicates with the second opening of the baffle 3, and the other corresponds to and communicates with the third opening of the baffle 3. It is ensured that the weldment can slide out of the placement tray 8.

[0029] like Figure 1 As shown, a support plate 14 is welded on the workbench 1, and a cylinder 15 is fixed by bolts on the top of the support plate 14. The output end of the cylinder 15 is vertically downward and fixedly connected to a fixing rod 16. The fixing rod 16 is horizontally placed and arranged along the radial direction of the workbench 1. A detector 17 is fixedly assembled on the bottom surface of the end of the fixing rod 16 close to the workbench 1. The detector 17 is located above the workbench 1 and is used to detect the surface quality of the welded parts.

[0030] like Figure 3 and Figure 4 As shown, two parallel and T-shaped slide seats 23 are welded on the support plate 14, and the upper limit sliding of the two slide seats 23 is matched with the same slide plate 22, and the slide plate 22 slides along the radial direction of the workbench 1 to approach or move away from the center of the workbench 1. A horizontal connecting shaft 24 is mounted on the slide plate 22 to slide along the radial direction of the workbench 1, and the connecting shaft 24 slides through the slide plate 22. The end of the connecting shaft 24 close to the center of the workbench 1 is fixedly connected to the second clamping plate 26, and the second clamping plate 26 corresponds to the first opening of the baffle 3 and matches the notch on the placement plate 8. The second clamping plate 26 is in contact sliding cooperation with the placement plate 8. When the second clamping plate 26 is in sliding cooperation with the placement plate 8, the second clamping plate 26 cooperates with the first clamping plate 11 in the placement plate 8 to clamp and position the welded parts in the placement plate 8. A third spring 25 is sleeved on the end of the connecting shaft 24 away from the center of the workbench 1, and one end of the third spring 25 is fixedly connected to the slide plate 22, and the other end is fixedly connected to the connecting shaft 24, which is used for buffering and resetting the second clamping plate 26.

[0031] The fixed rod 16 and the slide plate 22 are connected by a transmission mechanism, which is used to drive the slide plate 22 to slide closer to or away from the center of the workbench 1. The transmission mechanism includes a pressure plate 18, a second spring 20 and a connecting rod 21. A vertical guide rod 19 is welded on the support plate 14, and the pressure plate 18 is slidably matched with the guide rod 19. The pressure plate 18 is an L-shaped plate, consisting of a horizontal plate and a vertical plate. The guide rod 19 passes through the horizontal plate and slides with the horizontal plate, and the vertical plate is in contact transmission with the fixed rod 16, which is used to drive the pressure plate 18 to slide downward along the guide rod 19.

[0032] The second spring 20 is sleeved on the guide rod 19 , the top end of the second spring 20 is fixedly connected to the transverse plate of the pressure plate 18 , and the bottom end of the second spring 20 is fixedly connected to the support plate 14 , so as to push the pressure plate 18 to slide upward along the guide rod 19 .

[0033] The connecting rod 21 is located between the pressing plate 18 and the sliding plate 22, and the connecting rod 21 is arranged obliquely in the vertical plane. The top end of the connecting rod 21 is hinged to the horizontal plate of the pressing plate 18, and the bottom end of the connecting rod 21 is inclined toward the center of the workbench 1 and is hinged to the sliding plate 22. When the pressing plate 18 slides downward along the guide rod 19, the connecting rod 21 pushes the sliding plate 22 to slide along the slide seat 23 toward the center of the workbench 1, and when the pressing plate 18 slides upward along the guide rod 19, the connecting rod 21 drives the sliding plate 22 to slide along the slide seat 23 away from the center of the workbench 1.

[0034] like Figure 1 As shown, the fourth opening of the baffle 3 is used to place the welded part to be inspected into the placement tray 8 .

[0035] Working principle: in the initial state, the first opening, the second opening, the third opening and the fourth opening are respectively connected to a corresponding placement plate 8.

[0036] When in use, first place the welded part to be inspected in the corresponding placement tray 8 through the fourth opening of the baffle 3 through the notch of the corresponding placement tray 8. Then start the first stepper motor 4, the output shaft of the first stepper motor 4 drives the rotating block 5 to rotate, and the rotating block 5 drives all the rotating rods 6 to rotate 90 degrees. The rotating rods 6 drive the connected placement tray 8 to rotate. The placement tray 8 with the welded part to be inspected rotates 90 degrees around the rotation center of the rotating block 5 along with the connected rotating rods 6. In this process, since the end of the placement tray 8 away from the rotating block 5 is in sliding contact with the baffle 3, the notch of the placement tray 8 is blocked to prevent the welded part from being thrown out due to centrifugal force during rotation.

[0037] At this time, the notch of the placement tray 8 on which the welded parts to be detected are placed overlapped with and connected to the first opening of the baffle 3, and the second clamping plate 26 is directly opposite to the notch of the placement tray 8 on which the welded parts to be detected are placed, and at the same time, the placement tray 8 on which the welded parts to be detected are placed reaches the bottom of the detector 17. Then the cylinder 15 is started, and the output end of the cylinder 15 extends vertically downward and drives the fixed rod 16 to move vertically downward, and the fixed rod 16 drives the detector 17 to move downward and close to the welded parts to be detected. In this process, the fixed rod 16 contacts and abuts the vertical plate of the pressure plate 18, and then the fixed rod 16 pushes the pressure plate 18 to slide downward along the guide rod 19, the second spring 20 is compressed, and the pressure plate 18 drives the end of the hinged connecting rod 21 to move downward. The end of the connecting rod 21 hinged to the slide plate 22 pushes the slide plate 22 to slide along the slide seat 23 toward the center of the workbench 1. The slide plate 22 drives the connecting shaft 24 to move toward the center of the workbench 1 through the third spring 25, and the connecting shaft 24 drives the second clamping plate 26 to move toward the placement tray 8 where the welded parts to be inspected are placed.

[0038] When the second clamping plate 26 slides into the placement tray 8 where the welded parts to be inspected are placed, the second clamping plate 26 contacts the welded parts to be inspected and pushes the welded parts to be inspected to contact the first clamping plate 11. Then, as the slide plate 22 gradually moves, the first clamping plate 11 and the second clamping plate 26 cooperate with each other to clamp and position the welded parts to be inspected. At this time, the third spring 25 is stretched, the first spring 10 in the placement tray 8 where the welded parts to be inspected are placed is compressed, and the detector 17 just reaches the detection height and detects the positioned welded parts.

[0039] After the detection is completed, the output end of the cylinder 15 retracts and resets, and drives the fixed rod 16 to move upward and reset. The fixed rod 16 drives the detector 17 to move upward away from the weldment and reset. In the process of the fixed rod 16 moving upward and resetting, due to the disappearance of the pressure of the fixed rod 16, the second spring 20 extends, and under the action of the elastic force of the second spring 20, the pressing plate 18 is pushed to slide upward along the guide rod 19, and the pressing plate 18 drives the end hinged with the connecting rod 21 to move upward, and the connecting rod 21 pulls the slide plate 22 to slide along the slide seat 23 away from the center of the workbench 1. At this time, due to the disappearance of the pulling force of the slide plate 22, the third spring 25 retracts and restores its natural length. At the same time, under the push of the slide plate 22, the third spring 25 pushes the connecting shaft 24 away from the weldment, and the connecting shaft 24 drives the second clamping plate 26 to move away from the weldment and gradually slide out of the placement tray 8. In this process, the second clamping plate 26 gradually breaks contact with the weldment, the first spring 10 gradually extends and restores its natural length, and at the same time, the first spring 10 pushes the first clamping plate 11 to reset.

[0040] When the pressing plate 18 is out of contact with the fixed rod 16, the second clamping plate 26 is reset and remains stationary. When the fixed rod 16 is reset, the first stepper motor 4 is started again, and the output shaft of the first stepper motor 4 drives the rotating block 5 to rotate 90 degrees again along the previous rotation direction, and all the rotating rods 6 rotate 90 degrees again along the previous rotation direction with the rotating block 5. At this time, the welded parts to be tested are placed in the next placement tray 8 through the fourth opening of the baffle 3. At the same time, the placement tray 8 on which the tested welded parts are placed rotates to the second opening of the baffle 3. If the test result of the tested welded parts is qualified, the second stepper motor 7 on the rotating rod 6 where the placement tray 8 is located is started, and the output shaft of the second stepper motor 7 drives the connected rotating shaft to rotate, and the rotating shaft drives the placement tray 8 to rotate downward along the through groove 9 corresponding to the second opening by a certain angle, and the tested welded parts in the placement tray 8 slide into the first collection box 12. If the test result of the tested welded parts is unqualified, the second stepper motor 7 is not started. When the next weld is inspected, all the rotating rods 6 rotate 90 degrees in the previous rotation direction again, and then the second stepping motor 7 is started to make the welds in the placing tray 8 slide into the second collecting box 13 .

[0041] Since the inspection process of other welded parts can be carried out by repeating the above process, it will not be described in detail here.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
