Description

Technical Field

[0001] This invention relates to the field of mechanism assembly technology, and in particular to an assembly and adjustment method for ensuring coaxiality consistency of a rotary support mechanism. Background Technology

[0002] Gear transmission, as the most important form of mechanical motion and power transmission, relies on the meshing between gear teeth to transmit motion and power. It is widely used due to its high transmission efficiency, compact structure, stability and reliability. However, problems that occur during assembly, adjustment and maintenance still need to be paid special attention to. Improper assembly and adjustment of gear transmission will aggravate tooth surface wear and even lead to tooth breakage and transmission failure.

[0003] The assembly and adjustment method of the mechanism is of great significance to the quality and performance of the entire transmission chain. Efficiency is an important parameter for evaluating the transmission performance of the mechanism. Transmission efficiency not only requires high-precision machining and manufacturing methods for parts, but also the installation accuracy and assembly and adjustment method of the mechanism are important factors affecting transmission efficiency. Excellent assembly and adjustment methods can ensure the stability of the transmission process, reduce noise and impact vibration during the process, and thus maintain the overall performance of the machine.

[0004] Existing gear assembly and adjustment methods generally rely on instruments such as dial indicators. This method is only suitable for the assembly and adjustment of conventional gears. The distance between the C-side of the slewing support mechanism clamping pair and the D-side of the mounting base is 16.5mm. The coaxiality consistency is controlled by measuring the distance between the two sides. Due to the limitations of testing time and space, it is not possible to obtain the deviation of 8 sets of slewing support mechanisms at the same time. Summary of the Invention

[0005] The technical problem solved by this invention is: This invention proposes an assembly and adjustment method for the coaxiality consistency of a rotary support mechanism. Combining the structural characteristics of the rotary support mechanism itself, it solves the technical problem that conventional assembly and adjustment methods cannot solve for the assembly and adjustment of rotary support mechanisms. It can achieve high-precision assembly and adjustment of special gear transmissions, which is of great significance for the long-term, efficient and stable operation of gears.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for adjusting the coaxiality consistency of a rotary support mechanism, comprising:

[0007] Several slewing support mechanisms are mounted on the guide rail;

[0008] Measure the distance between the mounting base and the mounting flange mounting surface of each slewing support mechanism, and adjust the shims by grinding to make each slewing support mechanism fit snugly with the mounting flange;

[0009] The professional measuring fixture is installed on one side of the slewing support mechanism through the mounting interface of the main clamping arm of the slewing support mechanism;

[0010] Use a feeler gauge to check the gap S between the special measuring fixture and the side surface D of the mounting base of the rotary support mechanism, and obtain the gap value, that is, measure the gap deviation of each rotary support mechanism at various points on the guide rail.

[0011] Based on the measured clearance deviations of each rotary support mechanism at various points on the guide rail, the relative positions of the clamping part of the rotary support mechanism and the mounting base are adjusted by adjusting the lead screw to ensure the coaxiality consistency of each rotary support mechanism, so that the coaxiality of the guide rail and the mounting flange meets the set requirements.

[0012] Furthermore, the dedicated measuring fixture has an L-shaped structure, including a mounting surface A and a measuring surface B. The mounting surface A is located on the side of the long side of the L-shaped structure, and the measuring surface B is located on the end face of the short side of the L-shaped structure. The mounting surface A and the measuring surface B are parallel to each other. The distance between the side C of the main clamping arm of the rotary support mechanism and the side D of the mounting base is converted into a gap S between the measuring surface B of the dedicated measuring fixture and the side D of the mounting base through the dedicated measuring fixture.

[0013] Furthermore, the distance between the mounting surface A and the measuring surface B of the special measuring fixture is equal to the distance between the side C of the main clamping arm of the rotary support mechanism and the side D of the mounting base.

[0014] Furthermore, the mounting surface A of the special measuring fixture has an opening in the middle, and the L-shaped structure has an acute-angle slot at the bend, which is used to cooperate with the rotary support mechanism for installation and to avoid interference with the rotary support mechanism.

[0015] Furthermore, the surface roughness of the mounting surface A of the special measuring fixture is Ra1.6 and the flatness is 0.015, the surface roughness of the measuring surface B of the special measuring fixture is Ra1.6 and the flatness is 0.015, and the parallelism of surface B relative to the mounting surface A is 0.025.

[0016] Furthermore, the coaxiality of the guide rail and the mounting flange is better than the requirement of φ0.2mm.

[0017] Compared with the prior art, the present invention has the following technical advantages:

[0018] (1) The method for coaxiality consistency of the rotary support mechanism provided by the present invention uses a special measuring tool to convert the distance between the clamping arm C surface of the rotary support mechanism and the mounting base D surface into the gap between the measuring surface B of the special measuring tool and the mounting base D surface, thereby simultaneously obtaining the deviation of 8 sets of rotary support mechanisms.

[0019] (2) The method for coaxiality consistency of the slewing support mechanism provided by the present invention solves the technical problem that the existing assembly and adjustment method cannot simultaneously obtain the deviation of 8 sets of slewing support mechanisms due to time and space limitations.

[0020] (3) The method for coaxiality consistency of the rotary support mechanism provided by the present invention, combined with the characteristics of the rotary support mechanism, designs a special tooling that can realize high-precision assembly and adjustment of the guide rail, laying the foundation for the meshing transmission of gear and guide rail, and is of great significance for efficient assembly and adjustment of special gear transmission methods.

[0027] The present invention will now be described in detail with reference to the accompanying drawings:

[0028] A method for coaxiality consistency of a slewing support mechanism, wherein the guide rail is connected to the mounting flange through the slewing support mechanism, and the slewing motion can be achieved by rolling friction generated by three rolling amplitudes in the slewing support mechanism;

[0029] Step 1: Install 8 sets of rotary support mechanisms 3 on the guide rail 2, so that the rollers 538 on the main clamping arm 531, the auxiliary clamping arm 532 and the bottom clamping arm 533 of each set of rotary support mechanisms 3 are completely in contact with the guide rail 2;

[0030] Step 2: Measure the distance between the mounting base 534 of the 8 sets of slewing support mechanisms 3 and the mounting surface of the mounting flange 1. Adjust the shims by grinding to make the 8 sets of slewing support mechanisms 3 fit completely with the mounting flange 1.

[0031] Step 3: Install the professional measuring fixture 4 on one side of the rotary support mechanism 3 through the mounting interface of the main clamping arm 531 of the rotary support mechanism 3.

[0032] Adjust the positional relationship of the 8 sets of rotary support mechanisms 3 relative to the mounting flange 1 to ensure that the coaxiality of the guide rail 2 and the mounting flange 1 is better than the requirement of φ0.2mm. Design a special measuring fixture 4 to convert the distance between the clamping arm C surface of the rotary support mechanism and the mounting base D surface into the gap between the measuring surface B of the special measuring fixture and the mounting base D surface, thereby obtaining the positional relationship of the 8 sets of rotary support mechanisms 3 relative to the mounting flange 1.

[0033] A special measuring fixture 4 is designed. Combining the structural characteristics of the rotary support mechanism 3, an installation interface 6 is provided in the main clamping arm 531 of the rotary support mechanism 3, which can be connected and fixed to the special measuring fixture 4 by screws.

[0034] The special measuring fixture 4 has an L-shaped structure, including a mounting surface A and a measuring surface B. The mounting surface A is located on the side of the long side of the L-shaped structure, and the measuring surface B is located on the end face of the short side of the L-shaped structure. The mounting surface A and the measuring surface B are parallel to each other. The special measuring fixture 4 converts the distance between the side surface of the clamping pair 304 of the control rotary support mechanism 3 and the side surface D of the mounting base 534 into the gap S between the measuring surface B of the special measuring fixture 4 and the surface D of the mounting base 534.

[0035] The special measuring fixture 4 has an opening designed in the mounting surface A to avoid interference with the structure of the rotary support mechanism 3;

[0036] Step 4: Using a special measuring tool 4 and a feeler gauge, check the fit between the special measuring tool 4 and the mounting base 534D of the rotary support mechanism 3, thereby measuring the gap deviation of the 8 sets of rotary support mechanisms 3 at various points on the guide rail 2.

[0037] Step 5: Based on the gap deviation of the 8 sets of rotary support mechanisms 3 installed at various points on the guide rail 2 as measured in Step 4, the relative position of the clamping part of the rotary support mechanism 3 and the mounting base 534 is adjusted by adjusting the lead screw 306, thereby ensuring the coaxiality consistency of the 8 sets of rotary support mechanisms 3 and achieving the requirement that the coaxiality of the guide rail 2 and the mounting flange 1 is better than φ0.2mm.

[0038] The rotary support mechanism 3 includes a clamping part and a mounting base 534. The clamping part is used to clamp the guide rail 2, and the mounting base 534 is fixedly connected to the mounting flange 1.

[0039] The clamping part includes a main clamping arm 531, a secondary clamping arm 532, and a bottom clamping arm 533. The bottom clamping arm 533 is directly mounted on the mounting base 534. The main clamping arm 531 and the secondary clamping arm 532 are respectively connected to the mounting base 534 via pins 535 and are capable of rotating around the axis. The main clamping arm 531 and the secondary clamping arm 532 are connected by clamping bolts 536. Each clamping arm is equipped with a freely rotatable roller assembly 537, and the roller assembly 537 has a retractable... The roller 538 rotates freely; the main clamping arm 531, the auxiliary clamping arm 532, and the bottom clamping arm 533 correspond to the outer inclined surface 522, the inner inclined surface 521, and the end face 523 of the guide rail, respectively; by tightening the clamping bolt, the outer ring surfaces of the rollers of the main clamping arm, the auxiliary clamping arm, and the bottom clamping arm can respectively adhere to the outer inclined surface, the inner inclined surface, and the end face of one end of the guide rail, forming a stable clamping state; by loosening and disengaging the clamping bolt from the auxiliary clamping arm, the auxiliary clamping arm can rotate around the pin shaft, so that the clamping part is in an open state.

[0040] Example:

[0041] like Figure 1 As shown, the present invention proposes an assembly and adjustment method for ensuring the coaxiality consistency of a rotary support mechanism, which includes using a specially designed measuring fixture 4 to measure the gap between the main clamping arm 531 and the mounting base 534 of 8 sets of rotary support mechanisms 3. By ensuring the consistency of the gap between the 8 sets of rotary support mechanisms 3, the coaxiality consistency between the 8 sets of rotary support mechanisms 3 and the guide rail 2 is ensured.

[0042] like Figure 2 , 3 As shown, the guide rail 2 is connected to the mounting flange 1 through the rotary support mechanism 3, and can achieve rotary motion by relying on the three rolling bearings in the rotary support mechanism 3. The left rolling bearing 301, the right rolling bearing 302, and the bottom rolling bearing 303 in the rotary support mechanism 3 form rolling friction with the left rolling surface, the right rolling surface, and the bottom rolling surface of the guide rail 2, respectively, which can reduce wear and stabilize the fluctuation of friction torque during rotation.

[0043] like Figure 4 , 5 As shown, in combination with the characteristics of the rotary support mechanism 3, a special measuring fixture 4 is designed. An installation interface is left on the main clamping arm 531 of the rotary support mechanism 3. It is fixed to the fixture 4 by four M3 mounting screws. The mounting surface A of the fixture 4 is connected to the C surface of the rotary support mechanism 3.

[0044] like Figure 6As shown, the distance between the main clamping arm 531C surface of the rotary support mechanism 3 and the mounting base 534D surface is 16.5mm. The purpose of controlling the coaxiality consistency is achieved by measuring the distance between the two surfaces C and D. Due to time and space limitations, the current method cannot simultaneously obtain the deviation of 8 sets of rotary support mechanisms 3. Therefore, a special measuring fixture 4 is designed.

[0045] like Figure 4 As shown, the distance between the mounting surface A and the measuring surface B of the special measuring fixture 4 is 16.5mm. The distance between the clamping pair 305C surface of the control rotary support mechanism 3 and the mounting base 534D surface is converted into the gap between the measuring surface B of the control special measuring fixture 4 and the mounting base 534D surface, thereby obtaining the deviation of 8 sets of rotary support mechanisms 3 at the same time.

[0046] like Figure 4 As shown, to ensure the accuracy of the measurement, the surface roughness of the mounting surface A of the special measuring fixture 4 is Ra1.6 and the flatness is 0.015, the surface roughness of the surface B of the special measuring fixture 4 is Ra1.6 and the flatness is 0.015, and the parallelism of surface B relative to the mounting surface A is 0.025.

[0047] like Figure 5 As shown, the special measuring fixture 4 has an opening to avoid structural interference between the special measuring fixture 4 and the rotary support mechanism 3;

[0048] like Figure 6 As shown, the distance between the mounting surface A and the measuring surface B of the special measuring fixture 4 is 16.5 mm. The distance between the main clamping arm 531C surface of the control rotary support mechanism 3 and the mounting base 534D surface is converted into the gap S between the measuring surface B of the special measuring fixture 4 and the mounting base 534D surface. The gap S between the measuring surface B of the special measuring fixture 4 and the mounting base 534D surface can be measured using a feeler gauge, thereby obtaining the deviation of 8 sets of rotary support mechanisms 3 at the same time.

[0049] like Figure 5 , 6 As shown, the slewing support mechanism 3 and the base 305 are connected in the form of a sliding table. The installation position of the slewing support mechanism 3 and the base 305 is adjusted according to the deviation to ensure the coaxiality consistency of the 8 sets of slewing support mechanisms 3 relative to the guide rail 2.

[0050] The parts of this invention not described in detail are well-known to those skilled in the art.
