However, existing detection device, often purely manual or automanual, detection efficiency is not high；And it detected
Human error is easy to produce in journey.
Based on the above issues, it is necessary to which the prior art is improved.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide thread measurement mechanism.
The utility model is achieved by the following technical solution: thread measurement mechanism, including workbench, in the work
It is provided with the conveying mechanism for conveying workpiece to be detected on platform, the end of the conveying mechanism is provided with the first piece-holder
Arm is provided with workpiece placement mechanism positioned at the first workpiece clamp gripping arm side, and the workpiece placement mechanism includes that interval is opposite
Two plate washers being arranged, two baffle are pushed by a driving mechanism so that two baffles can mutually be drawn close or mutually divide
From, any side baffle on be provided with motor, another side baffle is provided with respect to the position of motor output shaft to be turned
Dynamic fulcrum bearing；The first workpiece clamp gripping arm is used for piece-holder to be detected to the position being located between two baffles, and at this time two
Baffle is mutually drawn close, so that workpiece two sides to be detected are limited by motor output shaft and rotary branching holder, it further include using
In the visual sensor of detection workpiece thread parameter.
In above-mentioned technical proposal, the first workpiece clamp gripping arm includes L-shaped first and connect with described first
Second with v-shaped opening.
In above-mentioned technical proposal, the first workpiece clamp gripping arm level height is lower than the workpiece placement mechanism.
In above-mentioned technical proposal, the conveying mechanism includes delivery wheel and the belt that is stretched on delivery wheel, the table of belt
Face is provided with the seat for limiting the workpiece to be detected.
In above-mentioned technical proposal, the rear of the workpiece placement mechanism is provided with second workpiece clamping limb.
The utility model has the following beneficial effects: the utility model realizes the continuous high-efficient that axis class has thread part
The detection of rate thread parameter, structure is simple, and operation stability is high.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model.
Fig. 2 is the sectional perspective structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing: referring to Fig. 1 to Fig. 2,
Thread measurement mechanism, including workbench 1 are provided with the conveying mechanism 2 for conveying workpiece to be detected on the workbench 1,
The conveying mechanism 2 includes delivery wheel 20 and the belt (attached to be not shown in the figure) being stretched on delivery wheel, the surface setting of belt
Have a seat (attached drawing is not shown) for limiting the workpiece to be detected, above-mentioned seat tool has the notch of matching workpiece, for limit to
Workpiece is detected, prevents it from generating the offset of position in transmission process on belt, and then influences subsequent mechanical hand to work to be detected
The clamping of part.
The end of the conveying mechanism 2 is provided with the first workpiece clamp gripping arm 3, is located at the first workpiece clamp gripping arm side
It is provided with workpiece placement mechanism 4, the first workpiece clamp gripping arm 3 includes L-shaped first 30 and connect with described first
Second with v-shaped opening 31, when workpiece from the end of conveying mechanism 2 be detached from when, the axle portion at workpiece both ends, which is fallen into, to be located at
In second 31 with v-shaped opening, workpiece is clamped by above-mentioned first workpiece clamp gripping arm 3 at this time.The workpiece placement mechanism 4
Including being spaced two plate washers 40 being oppositely arranged, two baffle 40 is pushed by a driving mechanism 42 so that two baffles being capable of phase
It mutually draws close or is separated from each other, and be provided with motor 41 on the baffle 40 of any side, another side baffle is opposite
The position of motor output shaft is provided with rotary branching holder 43.The first workpiece clamp gripping arm level height is placed lower than the workpiece
Mechanism.
Firstly, working as the first workpiece clamp gripping arm 3 by way of rising and lifting workpiece for piece-holder to be detected to position
Position (detecting above-mentioned position by sensor) between two baffles, two baffles 40 are driven by driving mechanism 42 at this time
It mutually draws close, so that the two sides of workpiece to be detected are limited by motor output shaft and rotary branching holder, electric motor starting, passes through at this time
Preset revolving speed drives the workpiece rotation to be detected, further includes the visual sensor for detecting workpiece thread parameter, to
Workpiece is detected when rotating in preset speed, visual sensor, which passes through, scans workpiece to be detected in rotation, each position
Image, and described image is used to be compared with Workpiece standard parameter, and then judge whether the screw thread parameters of workpiece accord with
Close processing criterion.
The rear of the workpiece placement mechanism is provided with second workpiece clamping limb 5.When visual sensor judge it is to be detected
When workpiece complies with standard, by second workpiece clamping limb by above-mentioned piece-holder to the first station；When visual sensor judge to
When workpiece to be detected is not up to standard, by second workpiece clamping limb by above-mentioned piece-holder to second station.It is set by above-mentioned
It sets, will comply with standard automatically and not standard compliant workpiece distinguishes.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments.Above-described embodiment and explanation in the application
It is the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model the utility model described in book
