Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 3, in a saw tooth machining apparatus, a first traverse plate 10 capable of repeatedly moving back and forth along a horizontal X-axis direction and a horizontal Y-axis direction is disposed in a machine box 24, a clamping plate 11 repeatedly moving up and down along a vertical direction is disposed on the first traverse plate 10, a fixing member 12 is disposed on the clamping plate 11, a scale plate 18 for adjusting a cutting distance is disposed on the first traverse plate 10, and a grinding wheel 13 is disposed on one side of the first traverse plate 10.

Before the teeth grinding operation, according to the length requirement of the tooth form after the teeth grinding, the hand saw 17 is placed on the first traverse plate 10 and extends out of the first traverse plate 10 towards one side of the grinding wheel 13, according to the length requirement of the tooth form, the hand saw 17 is moved and is compared with the scale plate 18 to be moved to the corresponding scale, the clamping plate 11 is moved downwards to be close to the hand saw 17 along the vertical direction and is fixed on the first traverse plate 10 through the fixing part 12, then the first traverse plate 10 is close to the grinding wheel 13 rotating at high speed along the horizontal Y-axis direction so that the grinding wheel 13 cuts the hand saw 17, and after the cutting is finished, the first traverse plate 10 enables the grinding wheel 13 to be corresponding to the position of the next cutting point of the hand saw 17 along the horizontal X-axis direction.

The whole cutting work is completed by placing the clamping plate 11 in the case 24, metal chips which are cut at high speed and splashed collide with the inner end face of the case 24, the metal chips cannot splash out of the case 24 to cut workers or other devices, when the clamping plate 11 moves to be close to the bottommost end of the hand saw 17, a gap is formed between the clamping plate 11 and the hand saw 17, the fixing part 12 is adjusted according to the thickness of the hand saw 17, and the hand saw 17 is fixed by the fixing part 12.

The fixing part 12 comprises a plurality of limiting shafts 14 arranged at the bottom of the clamping plate 11, the limiting shafts 14 can move up and down repeatedly along the vertical direction, clamping blocks 15 are arranged at the bottom of the limiting shafts 14, gaps are formed between the clamping blocks 15 and the first traverse plate 10, and a hand saw 17 is arranged between the clamping blocks 15 and the first traverse plate 10.

When the clamping plate 11 drives the limiting shaft 14 to move downwards along the vertical direction to be close to the hand saw 17 to the bottom end, the limiting shaft 14 continues to move downwards along the vertical direction, so that the clamping block 15 at the end part of the limiting shaft 14 is abutted against the end face of the hand saw 17 and extrudes the hand saw 17, and the hand saw 17 is fixed between the clamping block 15 and the first traverse plate 10.

The limiting shaft 14 is in threaded connection with the clamping plate 11, the clamping blocks 15 are in a hexagon nut shape, and the shape and the size of each clamping block 15 in the hexagon nut shape are the same. It should be understood by those skilled in the art that the limiting shaft 14 may also be connected with an air cylinder or an oil cylinder, and the limiting shaft 14 is pushed by the operation of the air cylinder or the oil cylinder to drive the clamping block 15 to move towards the panel saw 17, but in this example, the thickness of the panel saw 17 may be changed according to the manufacturing requirement, and the distance for pushing the limiting shaft 14 by the operation of the air cylinder or the oil cylinder is a certain distance, if the panel saw 17 is too thick, the limiting shaft 14 may hit the panel saw 17 and cause the panel saw 17 to deform, and if the panel saw 17 is too thin, the panel saw 17 cannot be fixed, so in this example, the limiting shaft 14 is screwed with the clamping plate 11, and the clamping block 15 in a hexagon nut shape is screwed by a manipulator (not shown in the figure), so that the clamping block 15 moves downwards and presses the panel saw 17.

The limiting shafts 14 are arranged at equal intervals along the clamping plate 11. Because the hand saw 17 is longer, a larger reaction force can be generated in the cutting process of the grinding wheel 13, the limiting shafts 14 which are arranged at equal intervals can be evenly distributed and offset the reaction force, so that the hand saw 17 offsets the smaller reaction force through the self strength, if the two adjacent limiting shafts 14 are far apart, the part of the hand saw 17 between the two limiting shafts 14 can bear the larger reaction force in the cutting process, and the hand saw is easy to break under the condition of high-speed vibration.

The bottom of each clamping block 15 is provided with an elastic rubber cushion block 16, the rubber cushion block 16 is bowl-shaped, and the bowl opening of the bowl-shaped rubber cushion block 16 is placed towards the first traverse plate 10. Because the fixture block 15 and the hand saw 17 both have certain hardness and rigidity, in the process of extruding and fixing the hand saw 17 through the fixture block 15, if the limiting shaft 14 moves downwards for an overlong distance, the fixture block 15 can be extruded into the hand saw 17 to cause the damage of the hand saw 17, a rubber cushion block 16 is added between the fixture block 15 and the hand saw 17, the rubber cushion block 16 has elasticity, and has a buffering effect when the fixture block 15 extrudes the hand saw 17 to prevent the fixture block 15 from extruding and damaging the hand saw 17, the rubber cushion block 16 is in an inverted bowl shape, the rubber cushion block 16 extruded on the hand saw 17 extrudes air in the end face of the bowl shape, so that the internal pressure of the rubber cushion block 16 is smaller than the external pressure, the rubber cushion block 16 is adsorbed on the end face of the hand saw 17, and the fixed state of the hand saw 17 can be more stable.

The first traverse plate 10 is provided with two parallel scale plates 18, and the scale plates 18 are parallel to two sides of the panel saw 17. The hand saw 17 is placed in the two scale plates 18, the direction and the angle of the hand saw 17 are the same as those of the two scale plates 18, when the scales on the scale plates 18 are checked, the two ends of the hand saw 17 can be checked with the adjacent scale plates 18, the accuracy is improved, and meanwhile, the situation that the two ends of the hand saw 17 are not placed in parallel and the hand saw 17 inclines and the tooth form is different in the cutting process can be prevented.

The horizontal distance between the two scale plates 18 is the same as the length of the hand saw 17, and the hand saw 17 can extend into the space between the two scale plates 18 and is propped against and movably connected with the two scale plates 18. The distance between the two scale plates 18 is the same as the length of the hand saw 17, the hand saw 17 slides into the space between the two scale plates 18, the end surfaces of the two sides of the hand saw 17 are respectively contacted with the adjacent scale plates 18, the two ends of the hand saw 17 are prevented from being placed at a non-flush state, the manufacturing cost is reduced, and in addition, the end part of the hand saw 17 far away from the grinding wheel 13 is kept level with the corresponding scale number on the scale plates 18 according to the manufacturing requirement of the tooth-shaped length.
