Operation principle: referring to fig. 1, an orientation position 6 in the overall structure is used for placing a gear to be polished, in a specific operation process, firstly, the gear to be polished is placed on the orientation position 6, and firstly, a second electric push rod 11 is started to drive an L-shaped sliding seat 10 to move upwards, so that the gear to be polished is gradually contacted with a sand grinding belt 3, and the sand grinding belt 3 is in a relatively tight state through the gear to be polished and four disc wheels 4;
then, when the drive motor 2 and the servo motor 9 are started, it is necessary to ensure that the direction of rotation of the sanding belt 3 is opposite to the direction of rotation of the blank to be polished, for example: the sand grinding belt 3 rotates clockwise, the blank to be polished needs to rotate anticlockwise, the rotation speeds of the sand grinding belt 3 and the blank to be polished are equal, the sand grinding belt 3 continuously passes through the surface of the outer edge of the blank to be polished, so that the polishing and grinding actions of the blank to be polished are completed, and the blank to be polished can be polished in multiple positions in the rotation process between the sand grinding belt 3 and the blank to be polished;
it should be noted that: referring to fig. 3, the sanding belt 3 is fastened and tightened by four disc wheels 4, but in actual state, the lower side of the sanding belt 3 is "squeezed" upwards by the orientation site 6 to form a triangular area, so that the contact area between the blank to be polished and the sanding belt 3 is increased, and the stability in the belt transmission process can be promoted, here, the basic principle of sanding/polishing of the flexible sanding belt is that, in order to ensure that the flexible sanding belt can normally perform the sanding/polishing process, the flexible sanding belt does not maintain the contact state with the blank to be polished in a horizontal state, but contacts with the blank to be polished in a bending direction, and the essence is that: the flexible sand grinding belt is fully contacted with the blank to be polished, if the grinding/polishing force needs to be increased, the bending degree of the flexible sand grinding belt can be increased, and the process is shown in fig. 2, and the L-shaped sliding seat 10 is driven by the second electric push rod 11 to move upwards to increase the contact degree between the flexible sand grinding belt and the blank to be polished, so that two states of tight edges and loose edges appear at the positions of the two sides of the sand grinding 3 corresponding to the position 6 of the fixed position, and the two states are common problems in belt transmission;
for precision gear's machining precision, because the tight limit and the loose limit on the sanding belt are different to treat the "degree of contact" of polishing blank, can understand to treat that polishing blank applyed the power inequality, to this, add two first electric putter 5, drive guide post 19 and carry out the self-adaptation and remove, specifically: the tight edge is in a 'loose' state, thereby driving the 'contact degree' on the tight edge to be reduced and tending to loose edge, or the loose edge is in a 'tightening' state, thereby driving the 'contact degree' on the loose edge to be improved and tending to tight edge, and the aim is that: it is ensured that the degree of "contact" between the sanding belt 3 and the blank to be polished tends to be equal, thereby ensuring the polishing effect in the overall polishing process.

Technical advantage
Referring to fig. 3, in theory, the total length of the sand belt 3 is unchanged, only by changing the diameter of the blank to be polished, but changing the deformation state of the sand belt 3, then after a blank to be polished is placed on the orientation position 6, and after the gear finished to be polished is removed, the tight sand belt is "rebounded" under the elastic action, so that the sand belt 3 can be dislocated and deviated from the spindle reel 4, for which a quick response structure is required to be added, and the operation principle is matched with the overall polishing action, specifically as follows:
1) The sanding belt 3 is first passed through each connecting holder 7 during normal rotation, and polishing is started, i.e. the driving motor 2 and the servo motor 9 are simultaneously energized and started, in which process the energized electromagnet blocks 14 in the connecting holders 7 are also energized to generate an electromagnetic field, with the difference that: limiting the direction of energization in the energization electromagnetic block 14, such as: when polishing starts, repulsive force is generated between the two electrified electromagnetic blocks 14 to keep away, so that normal rotation of the sand grinding belt 3 is not interfered;
2) Similarly, when the polishing action is completed and the gear for completing polishing needs to be removed, the second electric push rod 11 needs to be started, the second electric push rod 11 is in an electrified state to enable the L-shaped sliding seat 10 to slide downwards, the electrified direction in the electrified electromagnetic blocks 14 is limited again by taking the motion state of the second electric push rod 11 as a reference, suction force is generated between the two electrified electromagnetic blocks 14, the two electrified electromagnetic blocks 14 are enabled to be in quick contact with each other, clamping of the abrasive belt 3 is completed, and the mounting positions of the quick reaction structures are limited, so that the abrasive belt 3 at the key positions is prevented from being deviated or misplaced, and the like.

a2: the first electric push rod 5 at the left side is not started, and the first electric push rod 5 at the right side drives the guide column 19 at the position to move to the right side;
a3: the first electric push rods 5 at the left side position and the right side position are started at the same time, and the two first electric push rods 5 drive the guide column 19 at the position to move leftwards;
when the force difference is negative:
a1-1: the first electric push rod 5 at the right side is not started, and the first electric push rod 5 at the left side drives the guide column 19 at the position to move to the right side;
a2-2: the first electric push rod 5 at the left side is not started, and the first electric push rod 5 at the right side drives the guide column 19 at the position to move to the right side;
a3-3: the first electric push rods 5 at the left side position and the right side position are started at the same time, and the two first electric push rods 5 drive the guide posts 19 at the positions to move to the right side.
Firstly, it should be explained that: in terms of the technical content of the first embodiment, when the sanding belt 3 rotates clockwise, the sanding belt 3 corresponding to the left position of the positioning bit 6 is a tight edge, and the sanding belt corresponding to the right position of the positioning bit 6 is a loose edge, and in theory, the force applied on the tight edge is greater than the force applied on the loose edge, so that the balance system is important, and the balance system is firstly combined to the diameter dimension D of the blank to be polished, wherein the dimension D is related to the gear product, and is not limited in detail herein: the initial position of the position 6 is preset, including the relative position of the L-shaped slide 10 and the diameter D in the orientation position 6 0 In the initial position, the entire sanding belt 3 is in a relatively tight state, and in this initial position, the two guide posts 19 are in a tangential state with respect to the tight sanding belt 3, i.e. without causing deformation of the sanding belt 3;
but when it is desired to switch between gears, e.g. D > D 0 When the belt polishing sand belt is placed on the orientation position 6, the sand belt 3 is more easily tightened under constant length, and the second electric push rod 11 is required to drive the L-shaped sliding seat 10 to move downwards by the distance D-D 0 The distance of i/2 and the inclination angle of the sanding belt 3 corresponding to the position of the positioning bit 6 will also decrease, which here needs to be combined with the principle of trigonometry, the sanding belt 3 corresponding to the positioning bit 6 forming an opposite triangular area;
and it should be noted that: with reference to the description of fig. 3, the force Fp to which the blank to be polished is subjected in the contact position with the sanding belt 3: fp= (pc×d0)/2 μ, where Pc is the output power of the servo motor 9, where μ is the coefficient of friction between the sanding belt 3 and the blank to be polished, but there is a difference in the forces experienced on the loose edge and the tight edge in actual positions;
the above triangle areas are described as follows: along with the continuous rotation process of the sand grinding belt 3, for the positions of two sides of the sand grinding belt passing through the blank to be polished, the guide posts 19 on the two sides do not participate in and interfere with the continuous rotation process of the sand grinding belt 3, but the guide posts 19 and the sand grinding belt 3 need to keep a contact state, so that the sand grinding belt 3 can be extruded towards the guide posts 19, the pressure of the sand grinding belt 3 on the guide posts 19 can be detected by the pressure sensor 20, the pressure value is used for judging the tight side and the loose side of the sand grinding belt 3, and as shown above, a pressure difference value is needed to be existed on the positions of two sides of the corresponding positioning bit 6 of the sand grinding belt 3, F1 and F2 replace the display value on the pressure sensor 20 on the left side position and the right side position respectively, so that the force difference value is represented by F0, and then F0=F1-F2;
and it is to be explained again that: if f1=f2 is the optimal ideal state of polishing the blank to be polished by the sand grinding belt 3, the moving mode of the guide post 19 is adjusted to further promote the sand grinding belt 3 on two sides of the blank to be polished to generate local deformation, so that two states of clamping or loosening of the sand grinding belt 3 are realized, namely the states A1, A2 and A3 or the states A1-1, A2-2 and A3-3 corresponding to the states;
binding to fp= (Pc x D0)/2 μ and f0=f1-F2; if one of F1 and F2 is used to "close" to Fp, the purpose is to: referring to fig. 3, there are three points on the blank to be polished, wherein only one point is used as the polishing position of the blank to be polished and the sanding belt 3, the other two sides are respectively in a tight side state and a loose side state, and the same "contact degree" of the blank to be polished on the three points is a more ideal polishing state, so that:
if F1 > F2, then the left-hand sanding belt 3 is in the tight state, the right-hand sanding belt 3 is in the loose state, and the force difference is positive, and the adjustment process is performed according to A1, A2 and A3, specifically: the contact degree born by the tight side state is reduced, the contact degree born by the loose side state is improved, or the two sides are performed simultaneously, if F1 is less than F2, the adjustment mode is consistent, and the adjustment mode is only a region in the direction;
while the purpose of simultaneous progress in respect of the two-sided direction is: the contact degree born by the two sides after adjustment is ensured to slowly trend to Fp, so that the contact degree at three points on the blank to be polished is ensured to trend to Fp, the contact degree of the whole blank to be polished is in a more ideal state, and the whole polishing process is ensured to be in an optimal and non-differential state.
To sum up: the polishing and grinding action is executed by taking the sand grinding belt as a main structure in the polishing action of the precise gear and by combining a belt transmission and bidirectional rotation operation principle, and the polishing and grinding action is specifically expressed as follows: the gear to be polished and the sand belt rotate in opposite directions, so that the sand belt can polish the gear in multiple directions, in the process, the gear polishing requirements of multiple different diameters can be met, on the basis, the force difference on the tight side and the loose side is used as reference data, the deformation action of the two first electric push rods on the sand belt is regulated, the stress on the tight side and the loose side corresponding to the two sides of the orientation position is kept balanced, and the polishing effect is promoted to be uniform.
