Description

Technical Field

[0001] The utility model relates to the field of detection fixtures, and more specifically, to a leak-proof processing detection fixture. Background Art

[0002] As Figures 1 to 3 shown in the workpiece 10, it includes a first top plate portion 101, a second top plate portion 102, and three flange portions 103. The first top plate portion 101 and the second top plate portion 102 are located at different heights respectively, and the three flange portions 103 are all arranged on the bottom of the first top plate portion 101. A plurality of perforations 104 are respectively and penetratingly formed in the first top plate portion 101 and the second top plate portion 102, and a plurality of through holes 105 and cutouts 106 are formed in the flange portions 103. Mounting holes 107 are further formed at both ends of the workpiece 10, and the inner wall of the mounting holes 107 is provided with chamfers. Since the number of hole positions and cutouts 106 of the workpiece 10 is large, during the processing, it is easy to have the situation of missed processing, especially it is easy to miss the chamfering process of the mounting holes 107. Therefore, it is necessary to detect each hole position and cutout 106 one by one. If visual inspection is used for detection, not only is the efficiency low, but also the inspectors are prone to fatigue due to the long detection time, and then missed detection may occur. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a leak-proof processing detection fixture that can detect whether the chamfer inside the mounting hole is missed in processing.

[0004] To achieve the above purpose, the leak-proof processing detection fixture provided by the utility model includes a bottom plate, an end detection component, and a control unit. A workpiece placement position is arranged on the bottom plate, and a stop block is arranged at one end of the workpiece placement position; the end detection component is arranged at one end of the bottom plate, and the end detection component includes a driving device, a movable seat, a chamfer detection rod, and a chamfer detector. The chamfer detection rod is arranged on the movable seat and protrudes towards the workpiece placement position. The driving device can drive the movable seat to move towards the workpiece placement position. The chamfer detector is arranged on the movable seat and is arranged opposite to the stop block. The chamfer detector can move synchronously with the chamfer detection rod. The chamfer detector is used to sense whether the stop block enters its detection range; the control unit is respectively connected to the driving device and the chamfer detector. The control unit is provided with an alarm module, and both the workpiece in-place detector and the chamfer detector can trigger the alarm module to issue an alarm.

[0005] As can be seen from the above solution, a chamfer detection rod is provided and is arranged corresponding to the mounting hole at the end of the workpiece; a chamfer detector is arranged opposite to the stop block. When the chamfer detection rod can be inserted into the mounting hole at the end of the workpiece, the stop block can enter the detection range of the chamfer detector, and the control unit can determine that the mounting hole of the workpiece has been chamfered; if the chamfer detection rod cannot be inserted into the mounting hole at the end of the workpiece, the stop block is outside the detection range of the chamfer detector. At this time, the control unit can determine that the mounting hole of the workpiece has not been chamfered and control the alarm module to give an alarm. The utility model can quickly detect whether the mounting hole of the workpiece has been chamfered and has the advantage of high working efficiency.

[0006] A further solution is that the free end of the chamfer detection rod is provided with a tip.

[0007] As can be seen from the above solution, by providing the tip, it is used to cooperate with the chamfer of the workpiece mounting hole.

[0008] A further solution is that the stop block is provided with two stop surfaces on the side facing the workpiece placement position, and the two stop surfaces are arranged in a stepped manner, or the stop block is provided with a protrusion on the side facing the workpiece placement position.

[0009] As can be seen from the above solution, through the above setting, it is used to cooperate with the concave and convex of the end face of the workpiece to realize the positioning of the end of the workpiece and facilitate the chamfer detection rod to align with the mounting hole of the workpiece.

[0010] A further solution is that a workpiece in-place detector is arranged in the workpiece placement position, and the workpiece in-place detector is connected to the control unit and is used to detect whether the workpiece is placed in place in the up and down direction; a plurality of detection rods and / or detection blocks are also arranged on the bottom plate, and both the detection rods and the detection blocks protrude upward.

[0011] As can be seen from the above solution, through the above setting, when any one of the detection rods and the detection blocks cannot be inserted into the corresponding hole position or notch of the workpiece, the detection rod or the detection block will lift the workpiece, so that the workpiece cannot trigger the workpiece in-place detector, and the control unit can determine that at least one hole position or notch of the workpiece is missing processing. At this time, the workpiece in-place detector triggers the alarm module to give an alarm to remind the staff, which has the advantage of high detection efficiency.

[0012] A further solution is that the plurality of detection rods at least include one of the following: a flange detection rod, a first top plate detection rod, and a second top plate detection rod; the plurality of detection blocks at least include one of the following: a flange detection block, a first top plate detection block, and a second top plate detection block.

If there is a missing processing phenomenon, the convex top plate detection rod and / or the top plate detection block will lift the workpiece, causing the workpiece to move away from the detection range of the workpiece in-place detector. At this time, the workpiece in-place detector triggers the alarm module to issue an alarm.

[0014] A further solution is that the protruding height of the flange detection rod is lower than the protruding height of the first top plate detection rod; the protruding height of the flange detection block is lower than the protruding height of the first top plate detection block.

[0015] As can be seen from the above solution, through the above settings, the flange detection rod and the flange detection block can only penetrate the holes on the workpiece flange part, and cannot contact the bottom wall of the first top plate part, avoiding misalignment and lifting of the workpiece.

[0016] A further solution is that the alarm includes at least one of the following: sound, light, vibration.

[0017] A further solution is that a limiting block is also arranged on the bottom plate, and the limiting block is arranged on one side of the workpiece placement position to limit the movement of the workpiece along the width direction of the bottom plate.

[0018] A further solution is that a limiting part is arranged on the side of the limiting block facing the workpiece placement position, and the limiting part is set as a planar structure, or the limiting part is set as a concave-convex structure.

[0019] A further solution is that at least two supporting blocks are also arranged on the bottom plate, and the two supporting blocks are respectively arranged at both ends in the length direction of the workpiece placement position. Description of the Drawings

[0031] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. Specific embodiments

[0032] Refer to Figures 4 to 9 , the leak-proof processing detection fixture provided in this embodiment includes a bottom plate 1, a control unit (not shown in the figure), and end detection components 2. The number of end detection components 2 is preferably set to two, and the two end detection components 2 are respectively arranged at both ends of the bottom plate 1 in the length direction.

[0033] A workpiece placement position for placing the workpiece 10 is provided on the bottom plate 1. A first stop block 3 and a second stop block 7 are respectively arranged at both ends of the workpiece placement position. The workpiece 10 is placed between the first stop block 3 and the second stop block 7 to limit the movement of the workpiece 10 along the length direction of the bottom plate 1.

[0034] Two end detection components 2 are respectively arranged on one side of the first stop block 3 and the second stop block 7. Each end detection component 2 includes a driving device 21, a movable seat 22, a chamfer detection rod 23 and a chamfer detector 24. The chamfer detection rod 23 is arranged on the movable seat 22 and protrudes towards the workpiece placement position, and the chamfer detector 24 is arranged on the movable seat 22 and is arranged opposite to the first stop block 3 or the second stop block 7. The driving device 21 can be a cylinder or a hydraulic cylinder, and the driving device 21 can drive the movable seat 22 to move towards the workpiece placement position, thereby driving the chamfer detection rod 23 and the chamfer detector 24 to move synchronously. The chamfer detection rod 23 is correspondingly arranged with the mounting hole 107 at the end of the workpiece 10. When the mounting hole 107 has a chamfer, the chamfer detection rod 23 can be inserted into the mounting hole 107; when the chamfer of the mounting hole 107 is missed in processing, the chamfer detection rod 23 cannot be inserted into the mounting hole 107, or the depth of the chamfer detection rod 23 inserted into the mounting hole 107 is relatively shallow. The chamfer detector 24 is used to sense whether the first stop block 3 or the second stop block 7 enters its detection range.

[0035] The control unit is respectively connected to the driving device 21 and the chamfer detector 24. The control unit is provided with an alarm module, and the chamfer detector 24 is preferably a proximity switch.

[0036] After the driving device 21 drives the chamfer detection rod 23 and the chamfer detector 24 to move towards the workpiece placement position, when the depth of the chamfer detection rod 23 inserted into the mounting hole 107 reaches the standard, the first stop block 3 or the second stop block 7 enters the detection range of the chamfer detector 24, triggering the chamfer detector 24 to send a in-place signal to the control unit, and it can be determined that the mounting hole 107 has a chamfer; when the chamfer detection rod 23 cannot be inserted into the mounting hole 107 or the depth of the chamfer detection rod 23 inserted into the mounting hole 107 does not reach the standard, the chamfer detector 24 fails to sense that the first stop block 3 or the second stop block 7 enters its detection range, and the chamfer detector 24 will not send a in-place signal to the control unit, or sends a not-in-place signal to the control unit, and it can be judged that the chamfer of the mounting hole 107 is missed in processing. At this time, the control unit controls the alarm module to issue an alarm. The alarm includes at least one of the following: sound, light, vibration.

[0037] Further, a tip is provided at the free end of the chamfer detection rod 23. The outer diameter of the tip becomes smaller closer to its end face, such that an annular inclined surface is formed on the outer peripheral wall of the tip. This inclined surface matches the chamfer of the mounting hole 107, enabling the entire tip to be inserted into the chamfered mounting hole 107. For the mounting hole 107 that has not been chamfered, the tip cannot be inserted into the mounting hole 107 or can only be inserted into the mounting hole 107 by a small part at most. At this time, a reaction force is exerted on the chamfer detection rod 23 by the periphery of the mounting hole 107 to block the chamfer detection rod 23 from moving further, that is, to block the movable seat 22 and the chamfer detector 24 from moving closer to the first stop block 3 or the second stop block 7. In this embodiment, the driving force of the driving device 21 is less than the reaction force exerted on the chamfer detection rod 23 by the mounting hole 107, which helps to avoid deformation of the workpiece 10 during the detection process.

[0038] Further, in combination with Figure 6 and Figure 3 , two stop surfaces 31 are provided on one side of the first stop block 3 facing the workpiece placement position. The two stop surfaces 31 are arranged in a stepped manner and are used to match the end of the workpiece 10, which can not only limit the movement of the workpiece 10 along the length direction of the bottom plate 1 but also limit the movement of the workpiece 10 along the width direction of the bottom plate 1, realizing the positioning of the end of the workpiece 10 to ensure that the chamfer detection rod 23 is aligned with the mounting hole 107. The first stop block 3 is provided with a first avoidance hole 32 penetratingly, and the first avoidance hole 32 is correspondingly arranged with the chamfer detection rod 23 and the mounting hole 107 of the workpiece 10 respectively, such that the chamfer detection rod 23 can pass through the first avoidance hole 32 and be inserted into the mounting hole 107.

[0039] In combination with Figure 7 and Figure 3 , a protrusion 71 is provided on one side of the second stop block 7 facing the placement position of the workpiece 10, which is used to cooperate with the end groove of the workpiece 10, and can not only limit the movement of the workpiece 10 along the length direction of the bottom plate 1 but also limit the movement of the workpiece 10 along the width direction of the bottom plate 1, realizing the positioning of the end of the workpiece 10 to ensure that the chamfer detection rod 23 is aligned with the mounting hole 107.

[0040] A third stop block 8 is provided on one side of the second stop block 7. The third stop block 8 is in an "L" shape and is used to cooperate with the end of the workpiece 10. A second avoidance hole 81 is provided on the third stop block 8, and the second avoidance hole 81 is correspondingly arranged with the chamfer detection rod 23 and the mounting hole 107 of the workpiece 10 respectively, such that the chamfer detection rod 23 can pass through the second avoidance hole 81 and be inserted into the mounting hole 107.

[0041] In Figure 5 and Figure 7Among them, a workpiece arrival detector 4 is provided inside the workpiece placement position. The workpiece arrival detector 4 is used to detect whether the workpiece 10 is placed in place in the up and down directions. The workpiece arrival detector 4 can be a pressure sensor, a distance sensor, or a proximity sensor.

[0042] A plurality of detection rods and / or a plurality of detection blocks are further provided on the bottom plate 1. The detection rods and the detection blocks both protrude upward and are used to be correspondingly arranged with each hole position or notch in the workpiece 10 one by one.

[0043] The plurality of detection rods include a flange detection rod 51, a first top plate detection rod 61, and a second top plate detection rod 62; the plurality of detection blocks include a flange detection block 52, a first top plate detection block 63, and a second top plate detection block 64. Specifically:

[0044] Corresponding to the three flange portions 103 of the workpiece 10, a flange detection assembly 5 is provided on the bottom plate 1. The flange detection assembly 5 includes a plurality of flange detection rods 51 and a plurality of flange detection blocks 52, which are used to be correspondingly arranged with the through holes 105 and notches 106 of the workpiece 10 one by one.

[0045] Corresponding to the first top plate portion 101 of the workpiece 10, a plurality of first top plate detection rods 61 and a plurality of first top plate detection blocks 62 are provided on the bottom plate 1, which are used to be correspondingly arranged with the perforations 104 on the first top plate portion 101 one by one.

[0046] Corresponding to the second top plate portion 102 of the workpiece 10, a plurality of second top plate detection rods 63 and a plurality of second top plate detection blocks 64 are provided on the bottom plate 1, which are used to be correspondingly arranged with the perforations 104 on the second top plate portion 102 one by one.

[0047] The protruding height of the flange detection rod 51 is lower than the protruding height of the first top plate detection rod 61, and the protruding height of the flange detection block 52 is lower than the protruding height of the first top plate detection block 62. That is, the protruding heights of the flange detection rod 51 and the flange detection block 52 do not exceed the bottom wall of the first top plate portion 101 of the workpiece 10, so as to avoid misaligned jacking of the workpiece 10.

[0048] A plurality of limit blocks 11 are further provided on the bottom plate 1. The plurality of limit blocks 11 are all arranged on the same side of the workpiece placement position and are used to limit the movement of the workpiece 10 along the width direction of the bottom plate 1. The limit blocks 11 are provided with limit portions on the side facing the workpiece placement position. The limit portions can be set as a planar structure, or the limit portions are set as a concave-convex structure. The shape of the limit portions is preferably matched with the shape of the side wall of the workpiece 10.

[0049] At least two supporting blocks 12 are further arranged on the bottom plate 1. The two supporting blocks 12 are respectively arranged at two ends in the length direction of the workpiece placing position. The two ends of the workpiece 10 are respectively supported on the supporting blocks 12 to control the height position of the workpiece 10 in the up and down direction, ensuring that the mounting holes 107 of the workpiece 10 can be aligned with the chamfer detection rod 23.

[0050] In summary, in the present utility model, the chamfer detection rod 23 is arranged to correspond to the mounting hole 107 at the end of the workpiece 10; the chamfer detector 24 is arranged opposite to the stop block. When the chamfer detection rod 23 can be inserted into the mounting hole 107 at the end of the workpiece 10, the stop block can enter the detection range of the chamfer detector 24, and the control unit can determine that the mounting hole 107 of the workpiece 10 has been chamfered; if the chamfer detection rod 23 cannot be inserted into the mounting hole 107 at the end of the workpiece 10 or the insertion depth is too shallow, the stop block is located outside the detection range of the chamfer detector 24. At this time, the control unit can determine that the mounting hole 107 of the workpiece 10 has not been chamfered and control the alarm module to issue an alarm. The present utility model can quickly detect whether the mounting hole 107 of the workpiece 10 has been chamfered and has the advantage of high working efficiency.

[0051] Finally, it should be emphasized that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
