Description

Technical Field

[0001] The utility model relates to the technical field of roller frame inspection tooling, in particular to a three-way adjustable double-position coaxiality measuring tooling for a roller frame. Background Art

[0002] Welding roller frames are primarily used for the welding, polishing, rubber lining, and assembly of cylindrical barrels. They can also be used in conjunction with other tooling for the assembly and welding of cones and segmented, unequal-diameter rotating bodies. The coaxiality of the roller frame's balance beam hole is a key indicator for inspecting the roller frame's quality. Because the balance beam holes are distributed on both sides of the roller frame's width and the span of the holes on the same side is large, existing balance beam hole coaxiality measurements require multiple datum conversions. This is not only prone to measurement errors, but also time-consuming and labor-intensive, resulting in low measurement efficiency. Large deviations in balance beam hole coaxiality can seriously affect subsequent boring accuracy and increase production costs. Different roller frames have different balance beam hole heights, widths, and lengths, often requiring a single hole coaxiality measurement tool, which has a narrow scope of application.

[0020] The specific embodiments of the utility model will be further explained in detail below in combination with the drawings.

[0021] As Figure 7 shown, Figure 7 is the three-dimensional structure diagram of the roller stand; it can be seen from the figure that the balance beam hole positions are distributed on both sides of the width of the roller stand, the hole span on the same side is large, and the existing balance beam hole coaxiality measurement needs to be converted multiple times to carry out measurement, which not only is easy to cause measurement error, but also is time-consuming and laborious, and the measurement efficiency is low; the utility model scheme is proposed to solve the above problems.

[0022] As Figure 1 , 2 , 3, 4 shown, Figure 1 is the three-dimensional structure diagram of the utility model; Figure 2 is the front view structure diagram of the utility model; Figure 3 is the side view structure diagram of the utility model; Figure 4 is the top view structure diagram of the utility model; a three-way adjustable double-position coaxiality measuring tool for roller stand, comprising a bracket 1, two crossbeams 2, two upper longitudinal beams 3, two lower longitudinal beams 4, a measuring arm 5, a measuring ring 6 and a plurality of fasteners, the bracket 1 in the shape of rectangle is arranged below the crossbeam 2, a plurality of reserved holes 101 for adjusting the distance between the two crossbeams 2 are arranged on the bracket 1, and the bracket 1 is fixed below the crossbeam 2 through the fasteners; the vertical measuring arm 5 is arranged at the lower end of the end of each crossbeam 2, the top of the measuring arm 5 is connected to the lower end of the crossbeam 2 through the fastener, the measuring ring 6 is arranged at the end of the measuring arm 5, and one lower longitudinal beam 4 is horizontally arranged between the two adjacent measuring arms 5, each lower longitudinal beam 4 is fixed on the two adjacent measuring arms 5 through the fastener, and a plurality of length adjustment holes 401 for adjusting the distance between the two measuring arms 5 are formed in the lower longitudinal beam 4; a plurality of width adjustment holes 201 for adjusting the width of the two lower longitudinal beams 4 are arranged on the crossbeam 2; the upper longitudinal beam 3 is in the structure of sleeve sleeve rod, the upper longitudinal beam 3 is vertically connected with the inner side of the crossbeam 2 through a connecting plate at both ends to form a rectangular frame, and the sleeve rod in the upper longitudinal beam 3 is adjusted in length following the fastener fixing position on the bracket 1.

[0023] A plurality of height adjustment pads 7 for adjusting the height of the two crossbeams 2 are arranged below the bracket 1.

[0024] A plurality of handles 8 for gripping are arranged on the crossbeam 2.

[0025] The fasteners include bolts, nuts and spring washers.

[0026] The measuring ring 6 is replaceable with a measuring ring 6 having different inner diameters.

[0027] The working process of this utility model is as follows: Figure 5 、 6 As shown, Figure 5 This is a side view of the utility model in the installation and measurement state; Figure 6 This is a front view of the utility model during installation and measurement. First, the length, width, and height dimensions of the balance beam holes are determined based on the roller frame. Next, the widths of the adjacent measuring arms 5 and measuring rings 6 are adjusted by adjusting the positions of the fasteners in the reserved holes 101 on the bracket 1. This adjustment is done in terms of width between the two adjacent balance beam holes on the same side. The length of the balance beam holes on either side of the roller frame is adjusted by adjusting the positions of the fasteners in the width adjustment holes 201 on the crossbeam 2. Height adjustment is achieved by replacing height adjustment pads 7 of varying heights. The upper longitudinal beam 3 is a sleeve-and-rod structure. Each end of the upper longitudinal beam 3 is vertically fixed to the inside of the crossbeam 2 via a vertical connecting plate, forming a rectangular frame. The extension of the sleeve rods within the upper longitudinal beam 3 is adjusted according to the position of the fasteners on the bracket 1. Fasteners (bolts, nuts, and spring washers) are then used to secure the unit. The unit is then hoisted onto the roller frame using handles 8 for operation.

[0028] In actual application, since the size of the roller frame balance beam hole is not fixed, it is necessary to perform adaptive adjustment by replacing the measuring ring 6 with a different size, but the present invention is not limited to this.

[0029] The utility model is cleverly designed and can adjust the height, width and length in three directions at the same time, and can measure the coaxiality of the balance beam holes on both sides at the same time. It has a wide range of applications, greatly improves the inspection accuracy, reduces labor intensity, and solves the problem that the existing balance beam hole coaxiality measurement requires multiple conversions of the reference before measurement, which is not only prone to measurement errors, but also time-consuming and labor-intensive, with low measurement efficiency. The coaxiality deviation of the balance beam hole is large, which will also seriously affect the subsequent boring accuracy. The single measuring tool has a narrow scope of application and increases the production cost of the enterprise. Compared with the existing technology, it has good market prospects and development space.
