Description

Technical Field

[0001] The invention relates to the technical field of transmission shaft system assembly, and in particular to a dial indicator bracket used for transmission shaft system assembly. Background Art

[0002] The assembly of the transmission shaft system has certain requirements for coaxiality. In the actual operation process, each shaft section needs to be adjusted to meet the shaft alignment requirements. If the shaft is not aligned, the shaft system will vibrate and cause damage to related components. To detect shaft alignment, the dial indicator support is usually adsorbed on the mounting surface of one shaft section, the needle is pressed against the mounting surface of the other shaft section, and the shaft section adsorbed with the dial indicator support is rotated to measure the end face runout and radial runout of the mounting surface of the other shaft section. Specifically, if Figure 1 , Figure 2 As shown in the figure, when measuring shaft alignment, the dial indicator support is adsorbed on the first shaft segment, the dial indicator needle is pressed against the end face of the second shaft segment, and the first shaft segment is rotated to measure the end face runout; the dial indicator needle is pressed against the circumferential surface of the second shaft segment, and the first shaft segment is rotated to measure the radial runout. Figure 2 As shown in the figure, if the distance between the two shaft sections is large and the dial indicator is not long enough, the needle will not be able to reach the mounting surface of the second shaft section and shaft alignment measurement cannot be performed.

[0026] like Figures 1 to 12 As shown, some embodiments of the present invention disclose a support for a dial indicator 4 for assembling a transmission shaft system, including a base 1, an adjustment assembly and a dial indicator mounting seat 2. The base 1 has a mounting assembly that can be mounted to the first shaft segment 5. The adjustment assembly is mounted on the side of the base 1 away from the first shaft segment 5, and the dial indicator mounting seat 2 is arranged at the end of the adjustment assembly away from the base 1; the adjustment assembly is used to adjust the distance between the dial indicator mounting seat 2 and the base 1. In this embodiment, by providing an adjustment assembly, when in use, the base 1 is installed and fixed on the flange of the first shaft segment 5, and an elongated hole can be provided on the base 1 to accommodate flange installations of different diameters. The dial indicator 4 is installed on the dial indicator mounting seat 2, and by adjusting the distance between the base 1 and the dial indicator mounting seat 2, the use of the dial indicator 4 to perform shaft alignment measurement on two shaft segments at a long distance is achieved.

[0027] The dial indicator bracket 4 for assembling a transmission shaft system disclosed in some embodiments of the present invention is based on the above embodiments, such as Figure 3a , Figure 3bAs shown, the adjustment assembly may include a first rod 31, a second rod 32, a third rod 33, a hinge mechanism 36, a slide rod 34 and a slider 35; the slider 35 is adaptively mounted on the slide rod 34, and the second end of the third rod 33 is rotatably connected to the slider; two hinge seats are arranged at intervals on the base 1, and the first end of the first rod 31 and the first end of the second rod 32 are respectively rotatably connected to the hinge seats through the hinge mechanism 36; the second end of the first rod 31 and the first end of the third rod 33 are rotatably connected through the hinge structure. Through the connection mode of positionable rotation connection, the angle and position between different rods can be adjusted and positioned according to the required distance. Due to the existence of the slide rod 34 and the slide, the distance between the base 1 and the dial indicator 4 can be effectively increased. When in use, the base 1 is fixed on the first shaft section 5. By adjusting the angles between the first rod 31, the second rod 32, and the third rod 33 and the position of the slider 35 on the slide rod 34, the dial indicator 4 can be located at a position that can just resist the second shaft section 6, thereby realizing the axis alignment measurement. In order to better adjust the length and angle of the bracket, the length of the first rod 31 and the second rod 32 is designed to be equal in length L, but its length L is greater than the distance D between the two hinge holes on the base 1. In addition, a square sink area can be processed at the end of the slide rod 34 to improve its surface roughness and also to prevent scratches by other components. This area is set as the adsorption area of ​​the dial indicator 4, that is, the dial indicator mounting seat 2, which can better ensure the stability of the adsorption of the dial indicator 4.

[0028] In the above embodiment, in order to achieve a positionable rotatable connection, the hinge mechanism 36 may include a first connecting circular plate 361, a second connecting circular plate 362, an elastic member 363 and a connecting bolt 364; wherein, a first bolt hole is provided in the middle of the first connecting circular plate 361, and a second bolt hole is provided in the center of the second connecting circular plate 362; the first connecting circular plate 361 has a first contact surface with a concave-convex structure, and the second connecting circular plate 362 has a second contact surface with a concave-convex structure, the first contact surface and the second contact surface are arranged relatively closely, and the concave-convex structure of the first contact surface and the concave-convex structure of the second contact surface can be connected in an occlusive manner; the connecting bolt 364 passes through the first bolt hole, the second bolt hole and the elastic member 363; and the elastic member 363 clamps the first contact surface and the second contact surface in a tightly fitted manner during the occlusal connection. There are multiple first connecting circular plates 361, which are respectively fixedly mounted on the first end of the slide rod 34, the first end of the third rod 33 and one side of the hinge seat. The hinge seat has a third bolt hole, and the connecting bolt 364 passes through the third bolt hole; the second connecting circular plate 362 is fixed on the first end of the first rod 31, the first end of the second rod 32 and the second end of the second rod 32.

[0029] Specifically, the concave-convex structure may include a plurality of concave sector surfaces or convex sector surfaces arranged circumferentially around the center line of the connecting bolt 364. When the mounting surfaces (the first contact surface and the second contact surface) of the control hinge mechanism 36 are clamped and fitted, the concave and convex surfaces can be completely "engaged" to prevent loosening and sliding, thereby improving the stability of the hinge connection.

[0030] The dial gauge 4 bracket for assembling a transmission shaft system disclosed in some embodiments of the present invention is based on the above embodiments. The concave sector surface includes an arc-shaped concave bottom and two first side walls extending obliquely symmetrically from both sides of the bottom, and the extension line of the first side wall passes through the center line of the connecting bolt 364; the convex sector surface includes an arc-shaped convex top and two second side walls extending obliquely symmetrically from both sides of the top, and the extension line of the second side wall passes through the center line of the connecting bolt 364. The angle between the two first side walls is 145°; the angle between the two second side walls is 145°; the angle between the center lines of two adjacent concave sector surfaces is 30°; the angle between the center lines of two adjacent convex sector surfaces is 30°; the depth of the concave sector surface is 5mm, and the depth of the convex sector surface is 5mm. The concave and convex sector surfaces are dispersed from the center of the bolt light hole to the circumference, and a concave surface or a convex surface appears every 30°. It is more conducive to the movement and tightening between the two. When two rods (such as the second rod 32 and the third rod 33) are fastened together by the hinge mechanism 36, the engagement of the concave and convex sectors is as follows: Figure 8 As shown, the convex surface of the first connecting circular plate 361 fits with the concave surface of the second connecting circular plate 362 to prevent the two frame rods from rotating relative to each other, which can better play a stabilizing role. The setting of the concave and convex surfaces at the cover is only an example and can be selectively installed accordingly as long as they can achieve a tight fit with each other.

[0031] In the dial indicator bracket 4 for assembling a transmission shaft system disclosed in some embodiments of the present invention, based on the above embodiments, the elastic member 363 is an elastic disc, such as Fig. 9 As shown, the elastic disc includes an annular structure 3631; an elastic ring 3632 extending obliquely from the outer edge of the annular structure 3631 to the first side of the annular structure 3631; a cylindrical stop pressure platform 3633 extending vertically from the inner edge of the annular structure 3631 to the first side of the annular structure 3631; and a flanged arc 3634 extending obliquely from the outer edge of the elastic ring 3632 to the direction of the second side of the annular structure 3631; and the angle between the elastic ring 3632 and the plane where the annular structure 3631 is located is an obtuse angle; the height of the cylindrical stop pressure platform 3633 is less than the total height of the elastic disc. The height of the cylindrical stop pressure platform 3633 is one third of the total height of the elastic disc, and the height difference between the total height of the elastic disc and the cylindrical stop pressure platform 3633 is greater than 5 mm.

[0032] An elastic disc can be provided on both sides of the first connecting circular plate 361 and the second connecting circular plate 362, and fastened together by bolts and nuts (i.e., connecting bolts 364). Figure 1 As shown in . The main function of the elastic disc is to tightly fit the concave and convex surfaces of the first connecting circular plate 361 and the second connecting circular plate 362 together through its elastic deformation. Since the concave and convex surfaces have an inclined angle of 145° (small inclination) and a depth of only 5mm, when the length of the bracket needs to be adjusted, several rods are directly rotated for adjustment, without the need to loosen the bolts first and then rotate to adjust, which saves the process of loosening and tightening the bolts and improves efficiency; at this time, the elastic disc has been deformed, and when the convex surface of the first connecting circular plate 361 and the second connecting circular plate 362 is facing the convex surface, the deformation of the discs on both sides is 5mm in total, but the two rods are still in a clamping state. Continue to rotate the frame rod until the convex surface is positioned and engaged with the concave surface. The adjustment angle between the first connecting circular plate 361 and the second connecting circular plate 362 is a multiple of 30°, but the bracket as a whole has 5 hinge points, which can be freely combined and adjusted until it is adjusted to the desired position.

[0033] The elastic disc can be made of elastic steel, and the bottom is designed as a flanged arc 3634. When the elastic disc is deformed, the flanged arc 3634 at the bottom can reduce the sliding resistance caused by the deformation, and can also prevent the contact surface of the frame rod from being scratched. The pressure stop table (cylindrical pressure stop table 3633) designed inside the elastic disc has the main function of preventing the disc from being excessively deformed and damaged and losing its elastic effect when the elastic disc is compressed and deformed. The height M of the pressure stop table is 1 / 3 of the overall height N of the elastic disc, and NM>5mm.

[0034] The dial indicator 4 bracket for assembling a transmission shaft system disclosed in some embodiments of the present invention is based on the above embodiments. The cross section of the slide rod 34 is an inverted T-shaped structure. The slider 35 includes two straps placed on the two shoulders of the inverted T-shaped structure, two third side walls extending downward from the outer sides of the two straps, and a bottom wall connecting the bottom ends of the two third side walls. A plurality of ball sockets 351 are provided at the lower part of the straps. A ball 37 is installed in each ball socket 351. The radius of the ball socket 351 is 1.2 times the radius of the ball 37. The depth of the ball socket 351 is half the radius of the ball 37. The upper surfaces of the two shoulders are provided with arc-shaped rollers 341. The radius of the arc-shaped rollers 341 is 1.2 times the radius of the ball 37. The depth of the arc-shaped rollers 341 is half the radius of the ball 37. A mounting plate can be provided at the lower end of the bottom wall, and the hinge seat is fixedly mounted on the mounting plate.

[0035] In this embodiment, the slide rod 34 is a ⊥-shaped structure, and ball raceways (arc raceways 341) are arranged on both sides of the bottom (shoulder). In order to allow the ball to roll smoothly in the raceway, the raceway radius should be greater than the radius of the ball 37. The radius of the ball 37 is r, and the radius of the raceway is 1.2 times the radius of the ball 37, that is, 1.2r, and the raceway depth is r / 2. At the top of the slider 35, there are 6 ball sockets 351 for the ball 37 on both sides. Similarly, the ball sockets 351 have a radius of 1.2r and a depth of r / 2. The surface at the bottom of the slider 35 connected to the third rod 33 can be a plane, which can be adjusted at any angle. The ball 37 rolls between the slider 35 and the slide rod 34, and the slider 35 moves left and right to adjust the position. When adjusted to the appropriate position, tighten the bolts to support the slide rod 34, fix the position of the slider 35 and the ball 37, and then perform centering measurement. The rotation of several rods (the first rod 31, the second rod 32 and the third rod 33) combined with the sliding adjustment of the slider 35 can adjust the overall length and position of the bracket, which can be applied to the dial indicator 4 to measure the alignment runout of the shaft system over a long distance.

[0036] like Fig.12 As shown, some embodiments of the present invention disclose a dial indicator 4 bracket for assembling a transmission shaft system, wherein bolts pass through the elongated holes of the base 1 to fix the bracket on the flange of the first shaft segment 5, and the dial indicator 4 is adsorbed on the end of the bracket. According to the distance and position between the first shaft segment 5 and the second shaft segment 6, the rod and the slider 35 are adjusted so that the needle of the dial indicator 4 can be pressed against the mounting end face or circumferential face of the flange of the second shaft segment 6, and the first shaft segment 5 is rotated to measure the end face runout and radial runout respectively.

In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.

It should be understood by those skilled in the art that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present disclosure.
