DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] Such as Figures 1 to 4As shown in the figure, a positioning adjustment and detection device for milling the surface of a bridge housing according to an embodiment of the present utility model includes a base plate 1; a pair of mounting plates 12 are fixedly connected to the top of the base plate 1; a first side plate 13 is fixedly connected to the top of the mounting plate 12; a first bolt 14 is threadedly connected to the middle of the first side plate 13; one end of the first bolt 14 is rotatably connected to a clamping circular plate 15; the clamping circular plate 15 is arranged at one end of the first bolt 14 facing the other first bolt 14; during work, the bridge housing to be milled is placed between a pair of clamping circular plates 15, then first rotate a first bolt 14 to drive a clamping circular plate 15 to move, so that the position when the end of the bridge housing abuts against the side wall of this clamping circular plate 15 corresponds to the processing position, then adjust the position of the bridge housing so that the circular tubes at both ends of the bridge housing are concentric with the clamping circular plate 15, and then rotate the other first bolt 14 to drive the other clamping circular plate 15 to squeeze the bridge housing. After completion, the bridge housing will be squeezed and fixed in the middle by a pair of clamping circular plates 15 and then milled by a tool. Through the above structure, by observing whether the circular end faces at both ends of the bridge housing and the clamping circular plate 15 are in a concentric state, it can be quickly judged whether the bridge housing is in the correct initial processing position.
[0024] As Figures 1 to 3 shown, a pair of second side plates 2 are fixedly connected to the top of the mounting plate 12; a second bolt 21 is threadedly connected to the side wall of one of the second side plates 2; one end of the second bolt 21 close to the second side plate 2 is rotatably connected to a first wedge-shaped slider 22; the top of the first wedge-shaped slider 22 is slidably connected to a second wedge-shaped slider 23; the second wedge-shaped slider 23 is simultaneously slidably connected between a pair of second side plates 2; the top of the second wedge-shaped slider 23 is slidably connected to a bearing block 24; a V-shaped groove 25 is formed in the top of the bearing block 24; third bolts 26 are threadedly connected to the middle of a pair of second side plates 2; the bearing block 24 is located between a pair of third bolts 26; during work, the two ends of the bridge housing are respectively placed on a pair of bearing blocks 24, and the two ends of the bridge housing will slide into the inside of a pair of V-shaped grooves 25. Then, by rotating the second bolt 21 and the third bolt 26, the position of the bearing block 24 is adjusted so that the circular end faces at both ends of the bridge housing are in a concentric position with the clamping circular plate 15. Then, a pair of clamping circular plates 15 are used to clamp the bridge housing. After milling one bridge housing, move one clamping circular plate 15 away, then remove the bridge housing, and then place the two ends of a new bridge housing of the same specification on a pair of bearing blocks 24. Since the positions of a pair of bearing blocks 24 have not changed, after the two ends of the bridge housing sink into the inside of a pair of V-shaped grooves 25, the circular end faces at both ends of the bridge housing will directly be in a concentric position with a pair of clamping circular plates 15, thus quickly completing the determination of the initial processing position. Then, use the clamping circular plate 15 to clamp the bridge housing, and the bridge housing can be milled. Through the above structure, the same-specification bridge housings can be quickly positioned, thus facilitating the milling processing of a large number of same-specification bridge housings.
[0025] As shown Figures 1 to 4 in the figure, a pair of rotating rods 3 are rotatably connected to the top of the substrate 1; the other ends of the pair of rotating rods 3 are fixedly connected with a connecting rod 31; a clamping groove 32 is formed in the middle of the rotating rod 3; a pressing rod 33 is detachably installed in the middle of the clamping groove 32; a elastic cord 34 is fixedly connected to the middle of the pressing rod 33; the other end of the elastic cord 34 is fixedly connected to the middle of the connecting rod 31. During operation, after placing the axle housing on a pair of bearing blocks 24, rotate and place the pressing rod 33 inside the pair of clamping grooves 32. Then, under the pulling force of the elastic cord 34, the pressing rod 33 will not easily detach from the inside of the clamping groove 32. Then rotate the rotating rod 3 to make the pressing rod 33 press on the top plane of the axle housing. By pressing down the pressing rod 33, the inclined machining surface of the axle housing is rotated to the angle of the straight machining tool. After completion, then use the clamping circular plate 15 to clamp the axle housing. By observing whether the circular end faces at both ends of the axle housing and the clamping circular plate are concentric, it can be quickly detected whether the axle housing is in the correct initial machining position, thereby making the initial machining position of the axle housing more accurate, and further improving the milling surface accuracy of the axle housing.
[0026] As shown Figures 1 to 3 in the figure, a pair of cushion blocks 4 are symmetrically and fixedly connected to the middle of the V-shaped groove 25; a plurality of rollers 41 are rotatably connected to the opposite side walls of the pair of cushion blocks 4. During operation, after placing the axle housing on a pair of bearing blocks 24, the round tube at the end of the axle housing will contact the plurality of rollers 41. When using the pressing rod 33 to press down to adjust the angle of the machining surface of the axle housing, the axle housing will rotate. The setting of the rollers 41 can change the sliding friction between the end of the axle housing and the V-shaped groove 25 into rolling friction, thereby reducing the wear on the surface of the axle housing.
[0027] As shown Figures 1 to 4 in the figure, a plurality of clamping grooves 32 are formed in the middle of the rotating rod 3; the plurality of clamping grooves 32 are evenly distributed in the middle of the rotating rod 3. During operation, when it is necessary to adjust the angle of the machining surface of the axle housing, due to the unevenness of the machining surface of the axle housing, the pressing rod 33 can be placed inside the corresponding pair of clamping grooves 32, so that when the pressing rod 33 is pressed down, it can contact the flat part of the machining surface of the axle housing, thereby adjusting the angle of the axle housing. Through the above structure, the position of the pressing rod 33 can be adjusted according to the specific conditions of different machining surfaces of the axle housing, improving the applicability of the device.
[0028] As shown Figures 1 to 4As shown, a hook 5 is fixedly connected to the side wall of the rotating rod 3; the length of the rotating rod 3 is set to be greater than the distance between a pair of first side plates 13; during operation, after the angle adjustment of the machined surface of the axle housing is completed, the pressure rod 33 is taken out from the corresponding clamping groove 32, then the pressure rod 33 is placed inside a pair of hooks 5, and then the rotating rod 3 is rotated so that the movable end of the rotating rod 3 falls above the substrate 1, thereby reducing the space occupied by the rotating rod 3 during the machining of the axle housing, and further reducing the influence on surrounding objects.
[0029] As Figure 3 shown, a plurality of circular observation lines 6 are formed in the side wall of the clamping circular plate 15; the diameters of the plurality of circular observation lines 6 are different from each other, and the plurality of circular observation lines 6 are concentric with the clamping circular plate 15; during operation, when adjusting the position of the bearing block 24, the clamping circular plate 15 is brought close to the end of the axle housing, so that when adjusting the bearing block 24 to drive the end face of the axle housing to move, it is convenient to observe whether the end of the axle housing is concentric with the clamping circular plate 15 through the plurality of circular observation lines 6, improving the accuracy of the initial machining position of the axle housing, and further improving the accuracy of the milling surface of the axle housing.
[0030] During operation, the bridge housing to be milled is placed between a pair of clamping circular plates 15, and then a first bolt 14 is rotated to drive a clamping circular plate 15 to move, so that the position of the end of the bridge housing against the side wall of the clamping circular plate 15 corresponds to the processing position, and then the position of the bridge housing is adjusted to make the round tubes at both ends of the bridge housing concentric with the clamping circular plate 15, and then another first bolt 14 is rotated to drive another clamping circular plate 15 to squeeze the bridge housing. After completion, the bridge housing will be squeezed and fixed in the middle by a pair of clamping circular plates 15 and then milled by a tool, and the two ends of the bridge housing are respectively placed on a pair of bearing blocks 24. The two ends of the bridge housing will slide into a pair of V-shaped grooves 25, and then the position of the bearing block 24 will be adjusted by rotating the second bolt 21 and the third bolt 26, so that the circular end faces at both ends of the bridge housing are in a concentric position with the clamping circular plate 15, and then the bridge housing is clamped by a pair of clamping circular plates 15. After completing the milling of a bridge housing, a clamping circular plate 15 is removed, and then the bridge housing is removed, and then the two ends of a new bridge housing of the same specification are placed on a pair of bearing blocks 24. Since the position of a pair of bearing blocks 24 has not changed, after the two ends of the bridge housing are sunk into a pair of V-shaped grooves 25, the circular end faces at both ends of the bridge housing will be directly in and A pair of clamping circular plates 15 are concentrically positioned to quickly determine the initial processing position, and then the clamping circular plates 15 are used to clamp the bridge shell to mill the bridge shell. After the bridge shell is placed on a pair of bearing blocks 24, the pressure rod 33 is rotated to be placed inside a pair of card slots 32, and then the pressure rod 33 will not easily detach from the inside of the card slot 32 under the tension of the elastic rope 34, and then the rotating rod 3 is rotated to press the pressure rod 33 on the top plane of the bridge shell, and the inclined bridge shell processing surface is rotated to the angle of facing the processing tool by pressing the pressure rod 33 downward. After completion, the bridge shell is clamped using the clamping circular plate 15 After the bridge housing is placed on a pair of bearing blocks 24, the round tube at the end of the bridge housing will contact multiple rollers 41. When the angle of the bridge housing processing surface is adjusted by pressing down the pressure rod 33, the bridge housing will rotate, and the setting of the roller 41 can convert the sliding friction between the end of the bridge housing and the V-shaped groove 25 into rolling friction. When the angle of the bridge housing processing surface needs to be adjusted, due to the unevenness of the bridge housing processing surface, the pressure rod 33 can be placed inside the corresponding pair of grooves 32, so that the pressure rod 33 can contact the flat part of the bridge housing processing surface when pressed down, thereby adjusting the bridge housing angle.
