Description
Technical Field
The utility model relates to a nut detection device, concretely relates to projection welding nut leak protection mistake proofing detects frock.
Background
In automobile manufacturing, workpieces are mostly connected by projection welding nuts, the projection welding nuts are firstly welded in nut holes of one workpiece during welding, and the projection welding nuts are artificially missed or misplaced during production, so that the subsequent manufacturing process cannot be carried out, repair is caused, and even scrapped results can be caused. The problem that the missed placement of the projection welding nut is difficult to solve for a long time is that the rigidity mistake proofing and manual detection are adopted after the welding of the workpiece, the cost is high, active prevention cannot be achieved, the missed placement of the nut can only be detected, the inner diameter size of the nut cannot be detected, and the missed placement of the projection welding nut cannot be effectively detected.
The design of a detection device capable of effectively detecting the missing and misplacement of a projection welding nut in a workpiece is a problem to be solved urgently by researchers.
Disclosure of Invention
The utility model aims at providing a projection nut leak protection mistake proofing detects frock solves the projection nut that current detection means can't effectively prevent on the work piece and leaks to put, put assembly difficulty, inefficiency, rework that arouse by mistake and reprocess, lead to condemned problem even.
The utility model discloses a projection nut leak protection mistake proofing detection frock, including mount pad, fixed plate and guide pin bushing are fixed on the mount pad, and the guide pin bushing is located the lower part of mount pad, the fixed plate is located the same side of mount pad with the guide pin bushing, and is located guide pin bushing upper portion; the fixing plate and the guide sleeve are provided with mounting holes which are positioned on the same straight line, the guide pillar is sleeved in the mounting holes, the guide pillar is provided with a limiting block, and the limiting block is positioned on the upper part of the guide sleeve.
Furthermore, a proximity switch is arranged on the mounting seat, the proximity switch is located on the upper portions of the fixing plate and the guide post, and the proximity switch is connected with the indicating lamp.
Furthermore, a spring is arranged on the guide post between the limiting block and the fixing plate.
The utility model has the advantages that: because the guide pillar is sleeved on the fixed plate and the guide sleeve, the guide pillar is provided with the limiting block, the limiting block is positioned on the upper part of the guide sleeve, the guide pillar is sleeved on the fixed plate and the guide sleeve and cannot fall out, and when the lower part is stressed, the guide pillar can move upwards.
So when examining, the staff will wait to detect the work piece and aim at the guide pillar, go in establishing the nut hole that sets up the projection nut to the guide pillar cover, when waiting to detect and do not set up the projection nut in the work piece, the guide pillar stretches to the nut hole that sets up the projection nut in, does not receive ascending resistance, and the guide pillar is not mobilizable.
When the projection welding nut arranged in the workpiece to be detected is the staggered projection welding nut with the larger inner diameter, the guide pillar passes through the staggered projection welding nut hole, upward resistance is not applied, and the guide pillar does not move.
When a qualified projection welding nut is arranged in a workpiece to be detected, the guide column cannot penetrate through a nut hole of the correct projection welding nut, upward resistance is received, and the guide column moves upwards.
The utility model discloses simple structure can effectively detect out the work piece and leak and put projection nut, in time discovers and solves, has solved that current detection means can't effectively prevent projection nut on the work piece from leaking put, the assembly difficulty that the mistake was put and arouses, inefficiency, rework reprocess, lead to condemned problem even.

Detailed Description
The invention will be further described with reference to the accompanying drawings:
referring to fig. 1-4, a leak-proof and error-proof detection tool for projection welding nuts comprises a mounting base 1, a fixing plate 2 and a guide sleeve 3, wherein the fixing plate 2 and the guide sleeve 3 are fixed on the mounting base 1, the guide sleeve 3 is positioned at the lower part of the mounting base 1, and the fixing plate 2 and the guide sleeve 3 are positioned at the same side of the mounting base 1 and at the upper part of the guide sleeve 3; the fixing plate 2 and the guide sleeve 3 are provided with mounting holes on the same straight line, the guide pillar 4 is sleeved in the mounting holes, the guide pillar 4 is provided with a limiting block 41, and the limiting block 41 is positioned on the upper part of the guide sleeve 3.
During installation, the guide sleeve 3 is firstly installed on the installation seat 1, the guide post 4 is inserted into the installation hole of the guide sleeve 3, then the fixing plate 2 is sleeved on the guide post 4, and then the fixing plate 2 is fixed on the installation seat 1. During the detection, the worker aligns the guide pillar 4 to the workpiece 7 to be detected, and sets the nut hole of the projection welding nut 71 to the guide pillar 4, and when the projection welding nut 71 is not set in the workpiece 7 to be detected, the guide pillar 4 stretches into the nut hole of the projection welding nut 71, so that the upward resistance is not applied, and the guide pillar 4 is not moved. When the projection welding nut 71 arranged in the workpiece 7 to be detected is the staggered projection welding nut 71 with the larger inner diameter, the guide post 4 passes through the hole of the staggered projection welding nut 71 and is not subjected to upward resistance, and the guide post 4 does not move. When the qualified projection welding nut 71 is arranged in the workpiece 7 to be detected, the guide post 4 cannot pass through the nut hole of the correct projection welding nut 71, and receives upward resistance, so that the guide post 4 moves upward.
Furthermore, a proximity switch 6 is arranged on the mounting base 1, the proximity switch 6 is positioned on the upper portions of the fixing plate 2 and the guide column 4, and the proximity switch 6 is connected with an indicator light. When the qualified projection welding nut 71 is arranged in the workpiece 7 to be detected, the guide post 4 moves upwards, the top of the guide post is close to the proximity switch 6, the proximity switch 6 detects the guide post 4, so that an indication lamp opening instruction is sent, the indication lamp is bright, and a detector can visually observe that the workpiece 7 to be detected is a qualified piece.
The proximity switch 6 is a position switch that can be operated without mechanical direct contact with a moving part, and when the sensing surface of the object proximity switch reaches an operating distance, the switch can be operated without mechanical contact and any pressure applied, thereby driving a direct current electric appliance or providing a control command to a computer (plc) device.
Furthermore, a spring 5 is arranged on the guide post 4 between the limiting block 41 and the fixing plate 2. Therefore, when the guide post 4 moves upwards, the guide post needs to be moved upwards by a certain force, and the detection is more stable and accurate.
