Abstract
Disclosed is a lead wire clamping device for a stator wire rod. The lead wire clamping device comprises a pressure plate, and a current conducting plate, a copper pressure block and a screw clamp which are fixedly connected to the pressure plate, wherein the screw clamp comprises a round nut; a left shoe plate and a right shoe plate are arranged at two sides of the round nut; the left shoe plate and the right shoe plate are opposite to each other and are in symmetrical arrangement with the center line of the round nut; the left shoe plate and the right shoe plate are fixedly connected with the pressure plate respectively; and a holding down bolt is in threaded connection with the round nut inside the round nut. As the screw clamp of the utility model is of a separated structure composed of a round nut, a left shoe plate, and a right shoe plate, when the round nut is out of use, the user just needs to replace the round nut with a new one and welds the new round nut with the left shoe plate and the right shoe plate. Therefore, the interchangeability is enhanced and the cost of making the screw clamp is decreased.
Description
Technical field
The utility model belongs to through-flow unit stator winding processing and fabricating technical field, particularly a kind of stator bar lead-in wire clamping device.
Background technology
At present, through-flow unit stator winding bar line stick adopts mould pressing process processing, the gel mould and over the ground shaping mould need dispose the lead-in wire clamping device, realize compressing of bar line stick two ends lead-in wire by the copper briquetting that is connected the hold-down bolt on the down-lead card orchid and be fixed on the pressing plate, heating in the pressing process with coil itself as heater element, pass to low-voltage, high-current with voltage regulator, adopt the pressure oil of Hydraulic Station output, produce by compacting technology.So the lead-in wire clamping device plays crucial effects in the production process of whole bar line stick.Present lead-in wire clamping device, the blue global design structure that adopts of down-lead card, the quantity of every through-flow unit bar line stick is more, need the frequent down-lead card orchid of using, the utilance height of down-lead card orchid, temperature distortion is serious, screw thread is impaired serious in the course of the work, thereby influence the pressurization dynamics of hold-down bolt, influence bar line stick compacting quality, cause the down-lead card orchid to scrap, finish a through-flow unit stator winding bar line stick and will scrap a plurality of down-lead card orchids usually, throw the new down-lead card orchid of system, cost of manufacture is higher.
Summary of the invention
The utility model provides a kind of cost of manufacture lower stator bar lead-in wire clamping device for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of stator bar lead-in wire clamping device, comprise pressing plate, be fixed in conductive plate, copper briquetting and Ka Lan on the pressing plate, described card orchid comprises round nut, the both sides of described round nut respectively are provided with a left supporting bracket and a right supporting bracket, the center line symmetry of described left supporting bracket and described round nut relative with described right supporting bracket, described left supporting bracket and described right supporting bracket are affixed with described pressing plate respectively, and described round nut internal thread is connected with hold-down bolt.
The utility model can also adopt following technical scheme:
The height of described round nut is greater than the width of described left supporting bracket and described right supporting bracket.
The internal thread of described round nut is a trapezoidal thread.
Described left supporting bracket and described right supporting bracket are affixed by 45 soldered and described round nut respectively.
The blue two ends of described card are affixed by bearing pin and split pin and described pressing plate respectively.
Advantage and the good effect that the utlity model has are: by blocking the blue branch body structure of being arranged to comprise round nut, a left supporting bracket and a right supporting bracket, after round nut is scrapped, only need to change round nut, again with left supporting bracket and the welding of right supporting bracket, interchangeability is strong, has reduced the blue cost of manufacture of card; Round nut adopts trapezoidal thread, makes the blue stressed intensity enhancing of card, has prolonged the useful life of round nut; Adopt the structure of the height of round nut, improved the blue connection stability of card greater than left supporting bracket and right supporting bracket width.And the utility model is simple in structure, is convenient to operation, and convenient disassembly is time saving and energy saving, has alleviated operator's labour intensity.
