Description

Technical Field

[0001] This patent relates to the field of nut detection technology, and specifically to a multi-angle nut detection device. Background Art

[0002] In the parts manufacturing industry, such as Figure 1 As shown, some small parts 20 need to weld the first nut 21 and the second nut 22 on the back of the matching hole 2001 on the front or side thereof, so as to make them threadedly connected with other accessories. In order to facilitate subsequent processing, the first nut 21 and the second nut 22 must be accurately welded to the matching hole 2001 of the part 20 without misalignment. In the prior art, manual inspection is required to detect whether the nuts are welded accurately, which consumes manpower and time. Therefore, there is an urgent need for a detection device that can quickly determine whether the nuts on the front and side of small parts are welded accurately to improve the detection efficiency. Summary of the invention

[0003] The purpose of this patent is to design a multi-angle nut detection device so that it can quickly determine whether the nuts on the front and side of the part are welded accurately, so as to improve the detection efficiency.

[0004] To achieve the above purpose, this patent provides the following technical solutions:

[0005] A multi-angle nut detection device comprises a base, on which a workbench and a detection device are arranged;

[0006] The workbench includes a placement seat that is symmetrically arranged on the left and right, and the placement seat includes a first support column, the upper surface of the first support column matches the placement surface of the part to be detected, and a through hole is provided in the middle of the axis of the first support column. When the part to be detected is placed on the first support column, the first nut located on the front and back sides of the part to be detected is located in the through hole, and a gap is left between the second nut located on the side and back sides of the part to be detected and the placement seat; a clamping device is provided between the two placement seats, and the clamping device includes a first driving device and a clamping rod, and the clamping rod is driven by the first driving device to clamp the part to be detected on the placement seat;

[0007] The detection device corresponds to the placement seat, and the detection device includes a longitudinal detection mechanism and a transverse detection mechanism. The longitudinal detection mechanism and the transverse detection mechanism have the same structure, and both include a second driving device, a first sliding plate, a rotating motor and a detection screw; the second driving device is fixedly connected to the base through a fixing frame, and the driving end of the second driving device is fixedly connected to the first sliding plate through a connecting piece. The rotating motor is connected above the first sliding plate, and the driving end of the rotating motor is connected to the detection screw, and the detection screw is threadedly matched with the first nut and the second nut.

[0008] Furthermore, the first driving device is a rotary clamping cylinder, and the second driving device is a hydraulic cylinder. With such an arrangement, the rotary clamping cylinder and the hydraulic cylinder have simple structures and strong practicality. At the same time, when the parts to be inspected are placed, the rotary clamping cylinder drives the clamping rod to rotate to an angle that does not hinder the placement operation; when the placement is completed, the rotary clamping cylinder drives the clamping rod to rotate to an angle that enables the clamping rod to clamp the parts to be inspected. While facilitating placement, it can also ensure that the parts to be inspected are clamped.

[0009] Furthermore, a marking rod is provided on one side of the detection screw, and the marking rod is parallel to the detection screw; one end of the marking rod is fixedly connected to the rotating motor, and the other end of the marking rod is designed as a tip, and the tip end of the marking rod is shorter than the free end of the detection screw. With such a configuration, when the second drive device drives the rotating motor to move closer to the part to be detected, if the detection screw successfully passes through the first nut or the second nut, the tip of the marking rod will score the surface of the part to be detected to indicate that the part is a qualified product that has passed the test, and the structure is simple and practical.

[0010] Furthermore, the placement seat is also provided with a plurality of second support columns, the upper surfaces of which match the placement surface of the part to be detected. In this arrangement, the part to be detected is supported by the first support column and the second support column at the same time, so as to ensure the stability of the part to be detected after being placed on the placement seat.

[0011] Furthermore, the fixing frame is provided with a first slide rail, and the lower part of the first sliding plate is provided with a first slider slidably connected to the first slide rail. In this way, the first slide rail and the first slider cooperate to improve the stability of the first sliding plate when sliding relative to the fixing frame.

[0012] Furthermore, a contact sensor is provided on the connecting member, and a detection end of the contact sensor is aligned with the fixing frame; the contact sensor is electrically connected to the second driving device. In this way, the contact sensor is provided to ensure that a proper distance is maintained between the connecting member and the fixing frame, so as to avoid the connecting member and the fixing frame being too close to each other under the driving of the second driving device, thereby causing damage to the equipment.

[0013] Furthermore, a second sliding plate is provided between the first sliding plate and the rotating motor, the second sliding plate is fixedly connected to the rotating motor, and the second sliding plate is lockably slidably connected to the first sliding plate. With such an arrangement, considering the differences in the shapes of each batch of parts to be inspected, the distance between the detection screws and the placement seat of the transverse detection mechanism and the longitudinal detection mechanism also needs to be adjusted accordingly. In order to improve the adjustment efficiency, the rotating motor is fixedly mounted on the second sliding plate, and the second sliding plate is designed to be lockably slidably connected to the first sliding plate. In this way, the second sliding plate can be adjusted to a suitable distance and then locked. The structure is simple and practical.

[0014] Furthermore, the first sliding plate is provided with a second slide rail, and the lower part of the second sliding plate is provided with a second slider slidably connected to the second slide rail; an adjusting screw is connected to the side of the second sliding plate away from the placement seat, and the other end of the adjusting connection passes through the connecting member, and an adjusting nut is rotatably connected to the connecting member, and the adjusting screw is threadedly connected to the adjusting nut. In this arrangement, the stability of the second sliding plate when sliding relative to the first sliding plate is improved through the cooperation of the second slide rail and the second slider. In addition, when the distance needs to be adjusted, the adjusting screw can be driven by the second sliding plate to slide by rotating / reversely rotating the adjusting nut, and the structure is simple and practical.

[0015] Furthermore, a stop block is provided at one end of the second slide rail close to the placement seat, and a photoelectric sensor is provided at one end of the second slide rail away from the placement seat. In this way, the stop block is used to prevent the second sliding plate from being adjusted too close to the placement seat; when the photoelectric sensor detects that the second sliding plate is adjusted too far away from the placement seat, an alarm is given in time. If the second sliding plate needs to be disassembled and repaired from the rear end, the alarm can be ignored.

[0016] Furthermore, a torque sensor is provided inside the rotating motor, and an alarm device is also provided, and the alarm device is electrically connected to the torque sensor; the alarm device includes a buzzer and a flash light. In this arrangement, when the first nut or the second nut is misaligned with the matching hole of the part to be detected, and the detection screw driven by the rotating motor cannot smoothly pass through the part to be detected along the first nut or the second nut, the torque sensor detects that the rotation of the rotating motor will encounter resistance, and then the alarm device is activated, and the buzzer sounds and the flash light flashes, so as to promptly remind the operator to pay attention.

[0017] Compared with the prior art, the beneficial effects of this patent are:

[0018] Place the part to be tested on the placement seat, and then use the detection screws of the longitudinal detection mechanism and the transverse detection mechanism to move closer to the part to be tested, and observe whether the detection screw can pass through the first nut and the second nut of the part to be tested. If it can pass smoothly, it proves that the welding position of the first nut and the second nut on the part to be tested is correct.

[0019] The device can simultaneously detect and determine the first nut and the second nut located on the front and side of the part to be detected, thereby achieving multi-angle detection to improve detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to clearly and completely describe the technical solution in this patent in conjunction with the drawings in this patent, it is obvious that only a part of the embodiments of this patent is described, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0030] Example:

[0031] A multi-angle nut detection device comprises a base 1, on which a workbench 2 and a detection device 5 are arranged;

[0032] The workbench 2 includes a placement seat 3 that is symmetrically arranged on the left and right, and the placement seat 3 includes a first support column 301. The upper surface of the first support column 301 matches the placement surface of the part to be detected 20. A through hole 3011 is provided in the middle of the axis of the first support column 301. When the part to be detected 20 is placed on the first support column 301, the first nut 21 located on the front and back sides of the part to be detected 20 is located in the through hole 3011, and a gap is left between the second nut 22 located on the side and back sides of the part to be detected 20 and the placement seat 3; a clamping device 4 is provided between the two placement seats 3, and the clamping device 4 includes a first driving device 401 and a clamping rod 402. The clamping rod 402 is driven by the first driving device 401 to clamp the part to be detected 20 located on the placement seat 3;

[0033] The detection device 5 corresponds to the placement seat 3, and the detection device 5 includes a longitudinal detection mechanism 501 and a transverse detection mechanism 502. The longitudinal detection mechanism 501 and the transverse detection mechanism 502 have the same structure, and both include a second drive device 6, a first sliding plate 7, a rotating motor 8 and a detection screw 9; the second drive device 6 is fixedly connected to the base 1 through a firmware frame 10, and the driving end of the second drive device 6 is fixedly connected to the first sliding plate 7 through a connecting piece 12. The rotating motor 8 is connected above the first sliding plate 7, and the driving end of the rotating motor 8 is connected to the detection screw 9, and the detection screw 9 is threadedly matched with the first nut 21 and the second nut 22.

[0034] The first driving device 401 is a rotary clamping cylinder, and the second driving device 6 is a hydraulic cylinder. With such a configuration, the rotary clamping cylinder and the hydraulic cylinder have simple structures and strong practicality. At the same time, when the part 20 to be inspected is placed, the rotary clamping cylinder drives the clamping rod 402 to rotate to an angle that does not hinder the placement operation; when the placement is completed, the rotary clamping cylinder drives the clamping rod 402 to rotate to an angle that enables the clamping rod 402 to clamp the part 20 to be inspected. While facilitating placement, it can also ensure that the part 20 to be inspected is clamped.

[0035] A marking rod 11 is provided on one side of the detection screw 9, and the marking rod 11 is parallel to the detection screw 9; one end of the marking rod 11 is fixedly connected to the rotating motor 8, and the other end of the marking rod 11 is designed as a tip, and the tip end of the marking rod 11 is shorter than the free end of the detection screw 9. In this way, when the second driving device 6 drives the rotating motor 8 to move toward the part 20 to be detected, if the detection screw 9 successfully passes through the first nut 21 or the second nut 22, the tip of the marking rod 11 will score the surface of the part 20 to be detected, indicating that the part is a qualified product that has passed the test, and the structure is simple and practical.

[0036] The placement seat 3 is also provided with a plurality of second support columns 302, the upper surfaces of which match the placement surface of the part to be detected 20. In this way, the first support column 301 and the second support column 302 simultaneously support the part to be detected 20 to ensure the stability of the part to be detected 20 after being placed on the placement seat 3.

[0037] The first slide rail 1001 is provided on the fixture frame 10, and the first sliding plate 7 is provided with a first slider 701 slidably connected to the first slide rail 1001 at the lower part. In this way, the first slide rail 1001 cooperates with the first slider 701 to improve the stability of the first sliding plate 7 when sliding relative to the fixture frame 10.

[0038] The connecting member 12 is provided with a contact sensor 1201, and the detection end of the contact sensor 1201 is aligned with the fixture frame 10; the contact sensor 1201 is electrically connected to the second driving device 6. In this way, by providing the contact sensor 1201, it is ensured that a proper distance is maintained between the connecting member 12 and the fixture frame 10, so as to avoid the connecting member 12 and the fixture frame 10 being too close to each other under the drive of the second driving device 6, thereby causing damage to the device.

[0039] A second sliding plate 13 is provided between the first sliding plate 7 and the rotating motor 8, the second sliding plate 13 is fixedly connected to the rotating motor 8, and the second sliding plate 13 is connected to the first sliding plate 7 in a lockable sliding manner. With such a configuration, considering the differences in the shapes of the parts 20 to be inspected in each batch, the distance between the inspection screw 9 of the lateral inspection mechanism 502 and the longitudinal inspection mechanism 501 and the placement seat 3 also needs to be adjusted accordingly. In order to improve the adjustment efficiency, the rotating motor 8 is fixedly mounted on the second sliding plate 13, and the second sliding plate 13 is designed to be connected to the first sliding plate 7 in a lockable sliding manner, so that the second sliding plate 13 can be adjusted to a suitable distance and then locked, and the structure is simple and practical.

[0040] The first sliding plate 7 is provided with a second slide rail 702, and the lower part of the second sliding plate 13 is provided with a second slider 1301 slidably connected to the second slide rail 702; the side of the second sliding plate 13 away from the placement seat 3 is connected with an adjusting screw 1302, and the other end of the adjusting connection passes through the connecting member 12, and the connecting member 12 is rotatably connected with an adjusting nut 1202, and the adjusting screw 1302 is threadedly connected with the adjusting nut 1202. In this arrangement, the stability of the second sliding plate 13 when sliding relative to the first sliding plate 7 is improved through the cooperation of the second slide rail 702 and the second slider 1301. In addition, when the distance needs to be adjusted, the adjusting nut 1202 can be rotated / reversely rotated to make the adjusting screw 1302 drive the second sliding plate 13 to slide, and the structure is simple and practical.

[0041] A stop block 14 is provided at one end of the second slide rail 702 close to the placement seat 3, and a photoelectric sensor 15 is provided at one end of the second slide rail 702 away from the placement seat 3. In this way, the stop block 14 prevents the second slide plate 13 from being adjusted too close to the placement seat 3; when the photoelectric sensor 15 detects that the second slide plate 13 is adjusted too far away from the placement seat 3, an alarm is given in time. If the second slide plate 13 needs to be disassembled and repaired from the rear end, the alarm can be ignored.

[0042] The rotating motor 8 is provided with a torque sensor (not shown in the drawings) and an alarm device (not shown in the drawings), which is electrically connected to the torque sensor; the alarm device includes a buzzer and a flash light. In this arrangement, when the first nut 21 or the second nut 22 is misaligned with the matching hole 2001 of the part 20 to be detected, and the detection screw 9 driven by the rotating motor 8 cannot smoothly pass through the part 20 to be detected along the first nut 21 or the second nut 22, the torque sensor detects that the rotation of the rotating motor 8 will encounter resistance, and then the alarm device is activated, and the buzzer sounds and the flash light flashes to promptly remind the operator to pay attention.

[0043] The working principle of this embodiment:

[0044] The part to be detected 20 is placed on the first support column 301 and the second support column 302 of the placement seat 3, and the first nut 21 located on the front and back of the part to be detected 20 is located in the through hole 3011 of the first support column 301, and a gap is left between the second nut 22 located on the side and back of the part to be detected 20 and the placement seat 3. Then the first driving device 401 is started, and the first driving device 401 drives the clamping rod 402 to descend, and clamps and fixes the part to be detected 20.

[0045] The second drive device 6 and the rotating motor 8 of the longitudinal detection mechanism 501 and the transverse detection mechanism 502 are started at the same time, and the second drive device 6 drives the first sliding plate 7 to move closer to the placement seat 3 through the connecting piece 12, so that the detection screw 9 approaches the first nut 21 and the second nut 22. For the longitudinal detection mechanism 501, it is observed whether the detection screw 9 can pass through the first nut 21 of the part to be detected 20 and extend into the through hole 3011 of the first support column 301; for the transverse detection mechanism 502, it is observed whether the detection screw 9 can pass through the second nut 22 of the part to be detected 20 and extend into the gap. If it can pass through smoothly, it proves that the welding position of the matching hole 2001 of the part to be detected 20 and the first nut 21 and the second nut 22 is accurate and there is no misalignment.

[0046] The device can simultaneously detect and determine the first nut 21 and the second nut 22 located on the front and side of the part 20 to be detected, thereby achieving multi-angle detection to improve detection efficiency.

[0047] At the same time, the placement seat 3 and the detection device 5 are symmetrically arranged on the left and right sides, so that two parts can be detected at one time, and the detection efficiency is further improved.
