As shown in fig. 1 to 3, an automatic liquid-letting burn-prevention loading platform includes a substrate 1, a limiting plate 2, a main platform 3 for mounting a workpiece to be ground and a console assembly for controlling the reciprocating motion of the burn-prevention loading platform, wherein the limiting plate 2, the main platform 3 and the console assembly are all disposed at the top of the substrate 1 and are sequentially disposed along the length direction of the substrate 1, the limiting plate 2 is disposed along the vertical direction, the main platform 3 includes a sliding carriage 301 slidably disposed on the substrate 1 and a sliding seat 302 disposed at the top of the sliding carriage 301 and used for mounting the workpiece to be ground, a substrate dovetail spring seat 4 for resetting the sliding carriage 301 is disposed between the sliding carriage 301 and the limiting plate 2, a guide rail 9 for sliding the main platform 3 is disposed at the top of the substrate 1, and in this embodiment, in order to improve the stability of sliding, the guide rail adopts a groove-type guide rail.

The console assembly comprises a console support 5 fixedly arranged at the top of the base plate 1, a first torsion spring mechanism 6, a second torsion spring mechanism 7 and a drawing switch mechanism 8 are arranged on the inner side of the console support 5, wherein the first torsion spring mechanism 6 comprises a drawing torsion spring knob 601, a first torsion spring 602 and a first cam 603 used for driving the sliding frame 301 to reciprocate, which are sequentially connected through a first rotating shaft, and the first torsion spring mechanism 6 is used for driving the first cam 603 to rotate, so that the main rack 3 is pushed to reciprocate, namely to draw, towards the grinding advancing direction along a guide rail 9 on the base plate.

The second torsion spring mechanism 7 comprises a twitch control knob 701 and a second torsion spring 702 which are sequentially connected through a second rotating shaft, the outer sides of the first torsion spring 602 and the second torsion spring 702 are respectively provided with a first torsion spring seat 604 and a second torsion spring seat 703, and the outer walls of the first torsion spring seat 604 and the second torsion spring seat 703 are respectively provided with a single-tooth ratchet 605; the twitch switch mechanism 8 comprises a control pawl 801, a twitch switch 802 and a second cam 803 which are sequentially connected through a third rotating shaft, the control pawl 801 is provided with two control ends, the two control ends are respectively matched with single-tooth ratchets 605 arranged on the outer walls of a first torsion spring seat 604 and a second torsion spring seat 703, and the second torsion spring mechanism 7 is used for driving the single-tooth ratchets 605 to rotate and further used for controlling the interval of twitch actions of the main rack.

In the invention, the first torsion spring 602 is a main power component which continuously pushes the main rack 3 to reciprocate, the first cam 603 under the first torsion spring is continuously driven to rotate by the elastic torsion of the first torsion spring 602, the first cam 603 can continuously push the main rack 3 to reciprocate, and the second torsion spring 702 is a component which releases or closes the action of the first torsion spring 602, so that the grinding process cannot be influenced by continuous drawing due to overlarge elastic force of the first torsion spring 602.

When the reciprocating twitching of the burn prevention loading table is not needed, the twitching switch 802 can be rotated counterclockwise, and the second cam 803 below the twitching switch 802 blocks the rotation of the single-tooth ratchet 605, so that the control pawl 801 cannot swing to release the rotation of the first torsion spring 602, and the twitching of the main table frame 3 can be closed.

The twitching torsion spring knob 601, the twitching control knob 701 and the twitching switch 802 are all arranged on the outer side of the top of the console support 5, in order to achieve the best using effect, anti-reverse ratchets are arranged right below the twitching torsion spring knob 601 and the twitching control knob 701, and an anti-reverse pawl matched with the anti-reverse ratchets is arranged on the top of the console support 5.

Further optimize this scheme, the cavity is seted up to the bottom of second torsion spring seat 703 and is provided with the rubber pad in the cavity, this frequency that prevents burn mount table twitch can be adjusted through increasing rubber pad thickness, the thickness of rubber pad is big more, the frictional force between its and base plate 1 is big more, thereby can slow down the time that second

torsion spring mechanism

7 and 6 single rotations of first torsion spring mechanism need, adopt the rubber pad of different thickness to carry out the experiment respectively, as shown in fig. 4, the thickness of rubber pad in the picture (a) is greater than the thickness in the picture (b), obviously, when adopting the great rubber pad of thickness, this frequency that prevents burn mount table twitch will obviously be low, therefore, this frequency that prevents burn mount table twitch can be adjusted through increasing rubber pad thickness.

The principle of the invention is as follows: due to the existence of the anti-reverse ratchet wheel, the first torsion spring 602 and the second torsion spring 702 both rotate clockwise, when the twitch switch 802 rotates counterclockwise for a certain angle, the rotation of the single-tooth ratchet wheel 605 can not be blocked any more, so the single-tooth ratchet wheel 605 rotates clockwise due to the elastic force of the second torsion spring 702, the control pawl 801 is shifted once every time the single-tooth ratchet wheel rotates once, the control pawl 801 releases the rotation of the first cam and the first torsion spring once, the first cam 603 rotates for a circle to drive the main rack 3 to twitch for one time in a reciprocating way, in the twitch process of the main rack 3, a certain gap is generated between a ground workpiece and a grinding wheel, and grinding fluid enters a grinding arc area to be formed instantly.

Before the grinding machine is used, the corresponding torsion springs need to be tightened through the twitching torsion spring knob 601 and the twitching control knob 701, then the elastic force of the torsion springs is slowly released through an automatic mechanism, when a ground workpiece is machined, the grinding machine can automatically and uninterruptedly twitch in the grinding advancing direction, so that a gap is instantly formed between a grinding wheel and the ground workpiece, a large amount of grinding fluid is timely sent into a grinding arc area, and the twitch action is very small and the time is very fast, so that the whole grinding machining process is not influenced, the sufficient supply of the grinding fluid in the machining process is ensured, and the burning of the workpiece can be avoided.
