Description
Technical Field
The utility model relates to a welding wire production technical field especially relates to a guide pulley mechanism tests speed.
Background
In the welding wire production process, the conveying speed needs to be monitored constantly through a speed measuring mechanism. The traditional speed measuring mechanism is characterized in that a wire pressing wheel is arranged above a speed measuring wheel, welding wires are pressed on the speed measuring wheel, and the moving speed of the welding wires can be obtained through the rotating speed and the rotating number of the speed measuring wheel. However, the wire pressing wheel has a large mass, so that the wire may slip between the welding wire and the speed measuring wheel, the speed measuring wheel rotates, the welding wire does not move, the monitoring speed is higher than the actual speed, and the welding wire is easy to deform due to too tight pressing. If the weight of the wire pressing wheel is reduced, the welding wire is likely to move, the speed measuring wheel does not rotate, and the monitoring speed is lower than the actual speed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a guide pulley mechanism that tests speed that simple structure and monitoring result are accurate is provided.
The utility model discloses a realize through following technical scheme:
the utility model provides a guide pulley mechanism tests speed, its includes the mounting bracket, install the pivot of testing speed at the mounting bracket middle part, install at the outer tip of pivot that tests speed wheel, two push down the back shaft and install two on two push down back shafts and push down the bearing, install the encoder on the speed wheel, the mount has seted up the hole of stepping down in the top of pivot that tests speed, and the gliding backup pad that has clamped of hole department of stepping down, two push down the back shaft and install in the backup pad that pushes down, hole department fixed mounting that steps down has two springs, the top of spring and the bottom fixed connection who pushes down the backup pad.
Further, the mounting bracket is L-shaped structure, and comprises a horizontal mounting plate and a vertical mounting plate, mounting holes are formed in the horizontal mounting plate, and the speed measuring rotating shaft and the downward pressing supporting shaft are respectively mounted on the vertical mounting plate.
Furthermore, the speed measuring wheel and the two pressing bearings are respectively provided with welding wire grooves which correspond to each other along the circumferential direction.
The beneficial effects of the utility model
The utility model discloses a guide pulley mechanism tests speed has following advantage:
1. the structure is simple, and the cost is low;
2. the operation speed of the welding wire can be monitored in real time, and the monitoring result is accurate;

Detailed Description
The utility model provides a guide pulley mechanism tests speed, its includes the mounting bracket, install the pivot 10 that tests speed at the mounting bracket middle part, install at the outer tip of pivot that tests speed wheel 8, two back shaft 5 that push down and install two on two back shaft that push down and push down bearing 6, install encoder 4 on the speed wheel, the hole 11 of stepping down has been seted up in the top of pivot that tests speed to the mounting bracket, and the gliding backup pad 12 that has pressed down that clamps of hole department of stepping down, two back shaft that push down are installed in the backup pad that pushes down, hole department fixed mounting that steps down has two springs 9, the top of spring and the bottom fixed connection who pushes down the backup pad.
Further, the mounting bracket is L-shaped structure, including horizontal mounting panel 2 and vertical mounting panel 3, has seted up mounting hole 1 on the horizontal mounting panel, and horizontal mounting panel passes through bolt and frame fixed connection in mounting hole department, and the pivot that tests the speed and push down the back shaft and install respectively on vertical mounting panel, simple structure, the installation of conveniently making.
Furthermore, the speed measuring wheel and the two pressing bearings are respectively provided with a welding wire groove 7 which correspond to each other along the circumferential direction, so that the welding wire is prevented from sliding randomly, and the operation of the welding wire is more stable.
The utility model discloses a guide pulley mechanism tests speed, welding wire pass through the drive of drive mechanism, from the velocity measuring wheel top process to press the welding wire on the velocity measuring wheel through two lower pressure bearings, the welding wire operation drives the velocity measuring wheel rotation, and the encoder will calculate the speed that the welding wire moved according to the rotatory number of turns of velocity measuring wheel unit interval.
Because the utility model discloses a guide pulley mechanism tests speed changes a wire pressing wheel into two bearings and pushes down the welding wire, has reduced the deformation of welding wire, has increased the area of contact between welding wire and the velocity measuring wheel, and the welding wire can not skid, also can not be too tight because the welding wire presses, and the welding wire operation and the velocity measuring wheel do not change, and the monitoring result coincide with the speed of welding wire actual operation, and the monitoring result is accurate.
And let a hole department fixed mounting have two springs, the top of spring and the bottom fixed connection who pushes down the backup pad, through the buffering answer effect of spring, drive and push down the backup pad and slide from top to bottom, make and push down the bearing and give a stable pressure of welding wire all the time, further guarantee the accuracy of monitoring result.
To sum up, the utility model discloses a guide pulley mechanism tests speed, simple structure and monitoring result are accurate.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
