Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment assembly technology, specifically to an auxiliary measuring tool for mechanical equipment assembly. Background Technology

[0002] In the field of mechanical manufacturing and assembly, the machining, inspection and assembly of shaft parts are common processes. In this process, it is often necessary to support the shaft workpiece stably and accurately so as to perform operations such as scribing, centering, radial runout measurement, keyway machining or assembly with other parts. V-blocks are one of the most commonly used basic tooling tools to complete such tasks. They use V-grooves to position cylindrical surfaces and have the advantages of simple structure and easy use.

[0003] However, the angle of the V-groove in some existing fixed V-blocks is fixed. When two or more shafts of different diameters need to be installed, multiple V-blocks of different sizes are required to match so that the shaft centers of the different diameters are on the same horizontal line. This means that every time two or more shafts of different diameters are installed, the corresponding V-blocks need to be selected and replaced to make the shaft centers of the multiple shafts horizontal, which affects work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary measuring tool for assembling mechanical equipment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary measuring tool for assembling mechanical equipment, comprising a mounting base installed on the surface of a workbench, and further comprising: A first track groove is formed inside the mounting base. A support mechanism is installed on the surface of the first track groove. An extrusion block is provided on the top of the support mechanism. A threaded rod is internally threaded to the extrusion block. A second track groove is formed inside the mounting base, and a drive mechanism is mounted on the surface of the second track groove.

[0006] Preferably, the support mechanism includes a first V-shaped iron slidably connected to the surface of the first track groove, a second V-shaped iron slidably connected to the surface of the first track groove, and a guide rod fixedly connected inside the mounting base.

[0007] Preferably, the driving mechanism includes a sliding block slidably connected to the surface of the second track groove, a support seat fixedly connected to the top of the mounting base, a lead screw rotatably connected to the inner wall of the support seat, a rotating support fixedly connected to the top of the mounting base, and connecting rods fixedly connected to both sides of the sliding block.

[0008] Preferably, the surface of the first V-shaped iron is provided with a cylindrical rod, and the interior of the second V-shaped iron is provided with a circular hole, which is slidably connected to the cylindrical rod on the surface of the first V-shaped iron.

[0009] Preferably, the tops of the first V-shaped iron and the second V-shaped iron are provided with slots that have the same shape and size as the top of the extrusion block.

[0010] Preferably, the threads on the lead screw surface are arranged in opposite symmetrical configurations, and the height of the rotating support is lower than the axial height of the maximum diameter shaft to be tested when placed on the V-block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the drive mechanism and the support mechanism, allows the spacing between the V-blocks on both sides to be adjusted synchronously by rotating the lead screw. This enables the measuring tool to quickly and accurately adapt to shaft workpieces of different diameters, keeping the axis of the mounting shafts of different diameters on the same horizontal line, thus improving the work efficiency of the operator. At the same time, after the workpiece is placed, the workpiece can be stably pressed from above by the cooperation of the pressing block and the threaded rod, effectively restricting the axial and rotational degrees of freedom of the workpiece and ensuring the stability of the workpiece during measurement or scribing. This solves the problem of poor work efficiency caused by the need to prepare multiple V-blocks of different sizes when dealing with shafts of different diameters in some existing fixed V-blocks.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 As shown, an auxiliary measuring tool for assembling mechanical equipment includes a mounting base 1, which is mounted on the surface of a workbench to provide support and fixation for the device.

[0016] The mounting base 1 has two first track grooves 2 inside, which are symmetrically distributed at both ends of the mounting base 1.

[0017] A support mechanism 3 is installed on the surface of the first track groove 2. The support mechanism 3 includes two first V-shaped irons 31 that are slidably connected to the surface of the first track groove 2. Two second V-shaped irons 32 are slidably connected to the surface of the first track groove 2. A guide rod 33 is fixedly connected inside the mounting base 1. The inner cavity of the second V-shaped iron 32 is slidably connected to the guide rod 33.

[0018] The surface of the first V-shaped iron 31 is provided with a cylindrical rod, and the interior of the second V-shaped iron 32 is provided with a circular hole, which is slidably connected to the cylindrical rod on the surface of the first V-shaped iron 31, thereby making the first V-shaped iron 31 more stable when connected to the second V-shaped iron 32.

[0019] The support mechanism 3 is provided with a pressing block 4 on the top. There are four pressing blocks 4. The top of the first V-shaped iron 31 and the second V-shaped iron 32 are provided with slots that are the same shape and size as the top of the pressing block 4. The pressing block 4 is inserted into the slots on the top of the first V-shaped iron 31 and the second V-shaped iron 32.

[0020] The extrusion block 4 has internal threaded connections with threaded rods 5. The number of threaded rods 5 is the same as the number of extrusion blocks 4, and the threaded rods 5 are connected to the threaded holes at the top of the first V-shaped iron 31 and the second V-shaped iron 32.

[0021] By cooperating with the extrusion block 4, the first V-shaped iron 31 and the second V-shaped iron 32 can limit the position of the shaft to be tested, so that the shaft to be tested can be stably placed on the surface of the first V-shaped iron 31 and the second V-shaped iron 32.

[0022] The mounting base 1 has a second track groove 6 inside, which is located in the middle of the mounting base 1. A drive mechanism 7 is installed on the surface of the second track groove 6.

[0023] The drive mechanism 7 includes a sliding block 71 slidably connected to the surface of the second track groove 6, a support 72 fixedly connected to the top of the mounting base 1, a lead screw 73 rotatably connected to the inner wall of the support 72, the lead screw 73 being threadedly connected to the sliding block 71, a rotating support 74 fixedly connected to the top of the mounting base 1, the rotating support 74 being rotatably connected to the lead screw 73, and connecting rods 75 fixedly connected to both sides of the sliding block 71, the other end of the connecting rods 75 being fixedly connected to the surface of the first V-shaped iron 31 and the second V-shaped iron 32 on the same side.

[0024] There are two sliding blocks 71 and two support seats 72. The threads on the surface of the lead screw 73 are arranged in opposite directions and symmetrically, so that when the lead screw 73 is rotated, the two sliding blocks 71 can slide synchronously in opposite directions along the second track groove 6. The height of the rotating support 74 is lower than the axis height when the maximum diameter shaft to be measured is placed on the V-shaped iron, so as to avoid interference with the shaft to be measured.

[0025] By cooperating with the support base 72, rotating the lead screw 73 can drive the two sliding blocks 71 to slide in opposite directions along the surface of the second track groove 6. At the same time, under the action of the connecting rod 75, the two sliding blocks 71 can synchronously drive the first V-shaped iron 31 and the second V-shaped iron 32 on both sides to slide in opposite directions along the first track groove 2, thereby adjusting the distance between the first V-shaped iron 31 and the second V-shaped iron 32. This allows the device to adapt to shafts of different diameters, thereby aligning the axis of the shaft to be measured with the axis of another shaft to be measured, which facilitates installation by the staff. Furthermore, when the lead screw 73 rotates, under the joint support of the support base 72 and the rotating support 74, the lead screw 73 can rotate stably.

[0026] It is worth noting that the technical features such as the threaded rod 5 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0027] Working principle: First, install the mounting base 1 on the workbench surface. Then, adjust the distance between the first V-shaped iron 31 and the second V-shaped iron 32 according to the diameter of the shaft to be measured. Then, rotate the lead screw 73. Under the support of the support base 72 and the rotating support 74, the lead screw 73 drives the two sliding blocks 71 to slide symmetrically in opposite directions along the surface of the second track groove 6. At this time, under the action of the connecting rod 75, when the sliding block 71 slides, it drives the first V-shaped iron 31 and the second V-shaped iron 32 on the same side to move synchronously along the surface of the first track groove 2, thereby adjusting the distance between the first V-shaped iron 31 and the second V-shaped iron 32. Then, place the shaft to be measured... The shaft to be tested is placed on the surfaces of the first V-shaped iron 31 and the second V-shaped iron 32. The distance between the first V-shaped iron 31 and the second V-shaped iron 32 is then finely adjusted so that the axis of the shaft to be tested is on the same horizontal line as the axis of the other shaft with a side shaft. This aligns the axes of the two shafts, making it easier for the staff to install them. During this process, the height of the rotating support 74 will not affect the placement of the shaft to be tested. After the shaft to be tested is placed, the pressing block 4 is inserted into the top slot of the first V-shaped iron 31 and the second V-shaped iron 32. Finally, the threaded rod 5 is tightened to limit the position of the shaft to be tested, so that the staff can accurately measure the axis of the shaft to be tested.
