Description

Technical Field

[0001] The utility model belongs to the technical field of pistons, and in particular relates to a quality detection device for finished piston products. Background Art

[0002] The piston is an important component in the engine. It reciprocates in a straight line in a closed space. The main function of the piston is to withstand the combustion pressure in the cylinder and transmit this pressure to the crankshaft through the piston pin and connecting rod, thereby driving the engine to rotate and output power. The material of the piston needs to have sufficient strength, hardness, heat resistance and wear resistance. Quality inspection can ensure that the piston material has no defects, such as loose structure, low hardness, poor thermal stability, etc. The size and shape of the piston must be precise to ensure its correct movement and sealing effect in the cylinder. This includes checking the wear of the piston ring groove and whether the overall shape of the piston meets the design specifications.

[0003] In the quality inspection device for finished pistons in the prior art, the staff needs to put the finished pistons into the piston loader, use the control panel to operate the quality detector, and inspect the pistons in the piston loader one by one. When unqualified pistons are detected, the staff needs to manually take the unqualified pistons out of the piston loader and put them into the unqualified loading box, and the qualified ones into the qualified loading box. This operation is too cumbersome and requires the staff to pay attention to the data given by the quality inspection device all the time to see whether the pistons are qualified. If the staff misreads the data, the staff will confuse qualified pistons with unqualified pistons, which reduces the efficiency of piston quality inspection and increases the fault tolerance of piston quality inspection.

When an unqualified piston is detected, the piston falls from the piston loader and falls onto the inner surface of the positioning block, so that it falls steadily onto the pressure sensor. When falling, the piston applies downward pressure to the pressure sensor. The pressure sensor inputs an electrical signal to the motor through the controller, so that the motor starts working. The operation of the motor indirectly drives the clamping block, so that the clamping block pushes the piston into the upper surface of the conveyor belt.

When an unqualified piston falls into the pressure sensor, the pressure sensor starts the motor to operate through the controller. When the motor operates, the worm starts to rotate. Since the worm and the worm wheel are in a meshing relationship with each other, the rotation of the worm drives the worm wheel to start rotating. The worm wheel drives the connecting column to rotate together. The rotation of the connecting column drives the gear to rotate. Since the gear and the tooth plate are in a meshing relationship with each other, the rotation of the gear drives the tooth plate to move. The tooth plate moves along the sliding groove through the slider, so that the clamping block can move back and forth under the movement of the tooth plate, so that it completes the pushing and holding work.

[0048] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0049] like Figures 1 to 6 As shown, the embodiment of the utility model provides a quality inspection device for a piston finished product, comprising:

[0050] Box body 1: a storage assembly 2 is arranged inside the box body 1;

[0051] Detector 3: The lower surface of the detector 3 is fixedly connected to the inside of the box 1;

[0052] Piston loader 4: The lower surface of the piston loader 4 is fixedly connected to the inside of the box body 1;

[0053] Piston group 5: The piston group 5 is arranged inside the piston loader 4, and includes:

[0054] First piston 501: The first piston 501 is movably connected to the inner surface of the box body 1;

[0055] Second piston 502: A plurality of second pistons 502 are provided, and the lower surfaces of the plurality of second pistons 502 are movably connected to the inside of the piston loader 4;

[0056] Pressure sensor 6: The pressure sensor 6 is disposed inside the box body 1, and the upper surface of the pressure sensor 6 is movably connected to the lower surface of the first piston 501;

[0057] Motor 7: The upper surface of motor 7 is fixedly connected to the inside of box body 1;

[0058] Conveyor belt 8: The outer surface of the conveyor belt 8 is movably connected to the inside of the box 1;

[0059] Pushing and holding assembly 9: The pushing and holding assembly 9 is arranged inside the box 1, and a transmission assembly 10 is arranged at the right end of the pushing and holding assembly 9, including:

[0060] Clamping block 901: The outer surface of the clamping block 901 is movably connected to the outer surface of the first piston 501;

[0061] Positioning block 902 : The lower surface of the positioning block 902 is fixedly connected to the inside of the box body 1 .

[0062] refer to Figure 1 and Figure 3 As shown, a connecting assembly 12 is provided below the transmission assembly 10, and the transmission assembly 10 includes:

[0063] Tooth plate 1001: The left end surface of the tooth plate 1001 is fixedly connected to the right end surface of the clamping block 901, and a sliding component 11 is arranged below the tooth plate 1001;

[0064] Gear 1002: The outer surface of the gear 1002 is in meshing relationship with the outer surface of the toothed plate 1001 , and a power assembly 13 is disposed below the gear 1002 .

[0065] The above scheme is adopted: when the detector 3 detects that the piston on the piston loader 4 is unqualified, the first piston 501 falls from the piston loader 4, and the first piston 501 falls into the pressure sensor 6 along the inner wall of the positioning block 902. When the upper surface of the pressure sensor 6 senses the pressure of the first piston 501 falling, the pressure sensor 6 transmits an electrical signal to the motor 7 through the controller, so that the motor 7 starts to operate, and indirectly causes the gear 1002 to start rotating. Since the gear 1002 and the tooth plate 1001 are in a mutually meshing relationship, the rotation of the gear 1002 causes the tooth plate 1001 to start moving, and the tooth plate 1001 drives the clamping block 901, so that the clamping block 901 moves with the movement of the tooth plate 1001, and the movement of the clamping block 901 pushes the first piston 501 into the conveyor belt 8, so that the conveyor belt 8 drives the first piston 501.

[0066] refer to Figure 6 As shown, the sliding assembly 11 includes:

[0067] Sliding groove 1101: The sliding groove 1101 is provided on the lower surface of the tooth plate 1001;

[0068] Slider 1102 : The upper surface of the slider 1102 is slidably connected to the inner surface of the sliding groove 1101 , and the lower surface of the slider 1102 is fixedly connected to the inside of the box 1 .

[0069] With the above solution, the slider 1102 mainly supports the tooth plate 1001 , so that the sliding groove 1101 slides on the upper surface of the slider 1102 .

[0070] refer to Figure 4 As shown, the connection assembly 12 includes:

[0071] Connecting column 1201: The upper surface of the connecting column 1201 is fixedly connected to the lower surface of the gear 1002;

[0072] Connecting rod 1202: The left end surface of the connecting rod 1202 is rotatably connected to the output end of the motor 7;

[0073] Fixed block 1203: The upper surface of the fixed block 1203 is fixedly connected to the inside of the box body 1, and the right end surface of the fixed block 1203 is rotatably connected to the left end surface of the connecting rod 1202.

[0074] By adopting the above scheme, the rotation of the connecting column 1201 can drive the gear 1002 to rotate together; when the motor 7 starts to operate, it can drive the connecting rod 1202 to rotate; the fixing block 1203 mainly plays a role in keeping the connecting rod 1202 and the output end of the motor 7 in the same plane.

[0075] refer to Figure 3 As shown, the power assembly 13 includes:

[0076] Worm gear 1301: The upper surface of the worm gear 1301 is fixedly connected to the lower surface of the connecting rod 1202;

[0077] Worm 1302 : The outer surface of the worm 1302 is in meshing relationship with the outer surface of the worm wheel 1301 , and the inner surface of the worm 1302 is fixedly connected to the outer surface of the connecting rod 1202 .

[0078] Adopting the above scheme: when the connecting rod 1202 is driven by the motor 7 to start rotating, the connecting column 1201 can drive the worm 1302 to rotate synchronously. Since the worm 1302 and the worm wheel 1301 are in a mutually meshing relationship, the rotation of the worm 1302 drives the worm wheel 1301 to rotate, and the rotation of the worm wheel 1301 can drive the connecting rod 1202 to rotate.

[0079] refer to Figure 2 and Figure 5 As shown, the storage assembly 2 includes:

[0080] Storage tank 201: The bottom of the storage tank 201 is fixedly connected to the inside of the box body 1, and a pressure relief component 14 is arranged inside the storage tank 201;

[0081] Handle 202 : The right end surface of the handle 202 is fixedly connected to the left end surface of the storage slot 201 .

[0082] Adopting the above scheme: the first piston 501 falls into the storage groove 201 with the transmission of the conveyor belt 8. When the storage groove 201 is full of unqualified pistons, the staff can pull out the handle 202. Since the handle 202 is fixedly connected to the storage groove 201, the storage groove 201 can be pulled out at the same time when the handle 202 is pulled, and then it can be cleaned.

[0083] refer to Figure 2 As shown, the pressure relief assembly 14 includes:

[0084] Pressure relief spring 1401: four pressure relief springs 1401 are provided, and the bottoms of the four pressure relief springs 1401 are fixedly connected to the inside of the storage slot 201;

[0085] Pressure relief pad 1402 : The bottom of the pressure relief pad 1402 is fixedly connected to the upper end of the pressure relief spring 1401 .

[0086] With the above solution, when the first piston 501 falls into the receiving groove 201 , the falling first piston 501 applies downward pressure to the pressure relief pad 1402 . At this time, the pressure relief spring 1401 relieves the pressure of the first piston 501 falling and protects the receiving groove 201 .

[0087] The working principle of this utility model:

[0088] When in use, the staff puts the finished piston into the piston loader 4, and then controls the detector 3 to detect the piston in the piston loader 4. When the piston is detected to be unqualified, the unqualified piston falls safely along the positioning block 902 onto the upper surface of the pressure sensor 6. When the unqualified piston falls, downward pressure is applied to the pressure sensor 6. The pressure sensor 6 transmits an electrical signal to the motor 7 through the controller to start the motor 7. The operation of the motor 7 drives the connecting rod 1202 to cause the connecting rod 1202 to start rotating. Since the connecting rod 1202 is fixedly connected to the worm 1302, the rotation of the connecting rod 1202 drives the worm 1302 to rotate together. Since the worm 1302 and the worm wheel 1301 are in a mutually meshing relationship, the rotation of the worm 1302 drives the worm wheel 1301 to rotate. The worm wheel 1301 can drive the connecting column 1201 to cause the connecting column 1201 to rotate with the rotation of the worm wheel 1301. Since the connecting column 1201 is fixedly connected to the gear 1002, The connecting column 1201 rotates to drive the gear 1002 to start rotating. Since the gear 1002 and the tooth plate 1001 are in a mutually meshing relationship, the rotation of the gear 1002 drives the tooth plate 1001 to move. The tooth plate 1001 slides along the sliding groove 1101 under the support of the slider 1102. The tooth plate 1001 can drive the clamping block 901 to move. When the clamping block 901 moves, a thrust is applied to the unqualified piston to make it enter the conveyor belt 8. Under the action of the conveyor belt 8, the unqualified pistons fall into the storage groove 201. When the storage groove 201 is full, the staff can pull the handle 202. Since the handle 202 is fixedly connected to the storage groove 201, the handle 202 drives the storage groove 201 to be pulled out together. At this time, the staff can clean the unqualified pistons in the storage groove 201, thereby achieving the effect that when the detector 3 detects an unqualified piston, the staff does not need to manually put the unqualified piston into the unqualified storage groove 201.

[0089] To sum up: this quality inspection device for finished pistons, through the box body 1, storage component 2, detector 3, piston loader 4, piston group 5, pressure sensor 6, motor 7, conveyor belt 8, pushing component 9, transmission component 10, sliding component 11, connecting component 12, power component 13 and pressure relief component 14, solves the problem that in the existing quality inspection device for finished pistons, the staff needs to manually take out the unqualified pistons from the piston loader and put them into the unqualified loading box, and the staff needs to pay attention to the data given by the quality inspection device all the time to see whether the piston is qualified. If the staff misreads the data, the staff will confuse the qualified pistons with the unqualified pistons, thereby reducing the efficiency of piston quality inspection and increasing the fault tolerance rate of piston quality inspection.
