Abstract
The utility model relates to a wire winding resistance measuring apparatus mainly comprising a base plate, the base plate is fixedly connected with a lead rail and a bracket, the lead rail is connected with a sliding block is a sliding mode, the bracket and the sliding block are respectively and fixedly connected with a clamp head for disposing the two clamp heads of connecting resistance wires in a coaxial line, the two clamp heads are respectively connected with the resistance meter through conducting wires. The two clamp heads are clamped on a lead-out stick and the resistance wires are fixedly connected on the lead-out stick; the two clamp heads are connected with a pneumatic device. The utility model has useful effects that 1. the wire winding resistance measuring apparatus adopts copper which has a smaller resistivity as the material of clamp heads and adopts a pneumatic device to clamp the resistance wire tightly by using the clamp head, thus, direct contact between a human body and the resistance wire can be avoided; the clamping mode has a stable clamping force and a small constriction resistance and an improved accuracy degree of testing. 2. the resistance wires are undrawed by adopting a sliding block and lead rail mode, therefore, the undrawed resistance wires which are uniform and identical has a higher straightness.
Description
Technical field
The utility model relates generally to a kind of mechanical hook-up of protection and monitor field, mainly is a kind of wrapping wire measuring resistance device.
Background technology
Wrapping wire is the critical process in the electrothermal tube manufacturing process, and therefore the magnitude relationship of wrapping wire resistance can accurately measure wrapping wire resistance to the finished product resistance of electrothermal tube, to the big meaning of being manufactured with of electrothermal tube.Traditional wrapping wire resistance measurement method: when wrapping wire measured resistance value in the past, be that the resistance wire that will wind is set on the eduction rod, with the hands with the test pencil of ohmmeter by after to eduction rod, clutching, resistance wire drawn back reads resistance value.Because contacting of test pencil and eduction rod is that the degree of clutching with pointing is controlled, the contact resistance instability will cause the reading shakiness of resistance, causes error.And this method of testing, the resistance of human body also has been connected in parallel in the middle of the test loop, reading is not real resistance value, so this method measuring error is bigger.
Summary of the invention
The utility model will solve in the above-mentioned prior art not enough, and a kind of wrapping wire measuring resistance device is provided.
The utility model solves the technical scheme that its technical matters adopts: this wrapping wire measuring resistance device, mainly comprise base, be fixedly connected with guide rail and support on the described base, slidely connect slide block on the guide rail, be fixedly connected with a chuck on support and the slide block respectively, two chucks that are used to connect resistance wire are coaxially set, and two chucks are connected with ohmmeter by lead respectively.
Two chucks described in the utility model are clipped on the eduction rod, and resistance wire is fixedly connected on the eduction rod; Two chucks are connected with pneumatic means.
The effect that the utility model is useful is: 1, this device has adopted the material of the less copper of resistivity as chuck, and adopts pneumatic means with chuck resistance wire to be clamped, and has avoided human body directly to contact with resistance wire; This clamping mode clamping force is more stable, and contact resistance is little, has improved test accuracy.2, resistance wire draws back the mode that has adopted slide block and guide rail, makes the resistance wire linearity after drawing back higher, and uniformity.
