Description

Technical Field

[0001] The present invention relates to the technical field of worm assembly, and particularly to a guiding tool for worm installation on a machining center. Background Art

[0002] When the B-axis of a machining center is disassembled, repaired and assembled, the worm needs to be disassembled and installed. During the installation process of the worm, the requirement for centering is high. However, due to the small installation operation space and the inability to reach in with hands for operation, only a small pry bar can be used to slowly align and install, which easily causes the step surface of the inner ring of the bearing on the worm to hit the connection hole and easily damage the bearing, resulting in a very low installation efficiency of the worm. During the process of disassembling, repairing and assembling the B-axis once, the worm needs to be disassembled and assembled at least five times for disassembly, installation and adjustment. Due to the extremely low installation efficiency of the worm, it has a great impact on the entire repair, resulting in more than two shifts of time for each disassembly and repair of the B-axis, which has a greater impact on production. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a guiding tool for worm installation on a machining center aiming at the above deficiencies of the prior art. The guiding tool can quickly center and install the worm, reduce the workload of maintenance personnel, improve the maintenance efficiency, and has the characteristics of convenient use and strong practicability.

[0004] The technical solution adopted by the present invention is as follows: A guiding tool for worm installation on a machining center includes an installation sleeve body. The front section of the installation sleeve body is a guiding sleeve, and the rear section of the installation sleeve body is a connecting sleeve. The outer diameter of the connecting sleeve is equal to the outer diameter of the bearing on the crankshaft, and the outer diameter of the guiding sleeve is smaller than the outer diameter of the bearing on the crankshaft. An inclined structure is provided between the guiding sleeve and the connecting sleeve. The connecting sleeve is connected to the larger end of the inclined structure, and the guiding sleeve is connected to the smaller end of the inclined structure. A connecting hole for installing the crankshaft is provided on the installation sleeve body, and a support plate is provided in the connecting hole. A positioning cone is provided at the center of the support plate.

[0005] As a further improvement, the connecting sleeve, the guiding sleeve and the inclined structure are of an integral structure.

[0006] Furthermore, a plurality of first magnetic strips are inlaid on the inner wall of the connecting hole, and the plurality of first magnetic strips are arranged in parallel.

[0007] Furthermore, the installation sleeve body is composed of a left guiding sleeve and a right guiding sleeve symmetrically arranged and connected.

[0008] Furthermore, second magnetic strips are provided on the left guiding sleeve on both the upper and lower sides of the connecting hole, and magnetic strip grooves adapted to the second magnetic strips are provided on the right guiding sleeve on both the upper and lower sides of the connecting hole.

[0009] Furthermore, the outer diameter of the guiding sleeve is 5-10 mm smaller than the outer diameter of the bearing on the crankshaft.

[0010] Beneficial effects

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] A worm installation guiding tool for a machining center according to the present invention inserts the crankshaft into the connecting hole from the connecting sleeve section. Under the action of the positioning cone, the crankshaft is automatically installed and aligned in the connecting hole. When installing, the guiding sleeve is inserted into the installation hole of the crankshaft. Since the guiding sleeve is smaller than the outer diameter of the bearing, the guiding sleeve can be easily inserted into the installation hole. Then, under the action of the inclined structure, the connecting sleeve and the installation hole are automatically aligned, and at the same time, the bearing and the installation hole are aligned. After pushing forcefully, the crankshaft can be installed in alignment. The installation process can be aligned and installed at one time, greatly improving the installation efficiency, and at the same time avoiding damage to the bearing. It has the characteristics of convenient use and wide application range. Description of the drawings

Specific embodiments

[0018] The following further describes the present invention with reference to specific embodiments in the drawings.

[0019] Refer to Figures 1-4As shown in the figure, a worm installation guiding tool for a machining center according to the present invention includes an installation sleeve body 1. The front section of the installation sleeve body 1 is a guiding sleeve 2, and the rear section of the installation sleeve body 1 is a connecting sleeve 4. The outer diameter of the connecting sleeve 4 is equal to the outer diameter of the bearing 9 on the crankshaft 8, and the outer diameter of the guiding sleeve 2 is smaller than the outer diameter of the bearing 9 on the crankshaft 8. An inclined structure 3 is provided between the guiding sleeve 2 and the connecting sleeve 4. The connecting sleeve 4 is connected to the larger end of the inclined structure 3, and the guiding sleeve 2 is connected to the smaller end of the inclined structure 3. A connecting hole 15 for installing the crankshaft 8 is provided on the installation sleeve body 1. A support plate 5 is provided in the connecting hole 15, and a positioning cone 6 is provided at the central position of the support plate 5. The crankshaft 8 is inserted into the connecting hole 15 from the connecting sleeve 4 at the rear section. Under the action of the positioning cone 6, the crankshaft 8 is automatically installed and aligned in the connecting hole 15. During installation, the guiding sleeve 2 is inserted into the installation hole 10 of the crankshaft 8. Since the guiding sleeve 2 is smaller than the outer diameter of the bearing 9, the guiding sleeve 2 can be easily inserted into the installation hole 10. Then, under the action of the inclined structure 3, the connecting sleeve 4 and the installation hole 10 are automatically aligned, and at the same time, the bearing 9 and the installation hole 10 are aligned. After pushing forcefully, the crankshaft 8 can be installed in alignment. The installation process can be aligned and installed at one time, greatly improving the installation efficiency and avoiding damage to the bearing.

[0020] Specifically, the connecting sleeve 4, the guiding sleeve 2 and the inclined structure 3 are of an integral structure, which is integrally designed and formed, reducing subsequent processing procedures. At the same time, the coaxiality of the connecting sleeve 4 and the guiding sleeve 2 is better, which is beneficial to installation.

[0021] Preferably, a plurality of first magnetic strips 7 are inlaid on the inner wall of the connecting hole 15. The plurality of first magnetic strips 7 are arranged parallel to each other. When the crankshaft 8 is inserted into the connecting hole 15, the first magnetic strips 7 adsorb the crankshaft 8 to play a positioning role.

[0022] Furthermore, the installation sleeve body 1 is composed of a left guiding sleeve 11 and a right guiding sleeve 12 symmetrically arranged and connected. When disassembly is required, only the left guiding sleeve 11 and the right guiding sleeve 12 need to be separated, which is simple and fast.

[0023] Furthermore, second magnetic strips 14 are provided on the left guiding sleeve 11 on both the upper and lower sides of the connecting hole 15, and magnetic strip grooves 13 adapted to the second magnetic strips 14 are provided on the right guiding sleeve 12 on both the upper and lower sides of the connecting hole 15. Under the action of the second magnetic strips 14, the left guiding sleeve 11 and the right guiding sleeve 12 are adsorbed together.

[0024] Furthermore, the outer diameter of the guiding sleeve 2 is 5 - 10 mm smaller than the outer diameter of the bearing 9 on the crankshaft 8, so that the guiding sleeve 2 can be easily inserted into the installation hole 10. Then, under the action of the inclined structure 3, the connecting sleeve 4 and the installation hole 10 are automatically aligned, and at the same time, the bearing 9 and the installation hole 10 are aligned. After pushing forcefully, the crankshaft 8 can be installed in alignment. The installation process can be aligned and installed at one time, greatly improving the installation efficiency.

[0025] When a worm installation guiding tool for a machining center in this embodiment is in use, the crankshaft 8 is inserted into the connecting hole 15 from the connecting sleeve 4 at the rear section. Under the action of the positioning cone 6, the crankshaft 8 is automatically installed and aligned in the connecting hole 15. During installation, the guiding sleeve 2 is inserted into the installation hole 10 of the crankshaft 8. Since the guiding sleeve 2 is smaller than the outer diameter of the bearing 9, the guiding sleeve 2 can be easily inserted into the installation hole 10. Then, under the action of the inclined structure 3, the connecting sleeve 4 and the installation hole 10 are automatically aligned, and at the same time, the bearing 9 and the installation hole 10 are aligned. After pushing forcefully, the crankshaft 8 can be installed in alignment. The installation process can be aligned and installed at one time, greatly improving the installation efficiency and avoiding damage to the bearing. A worm installation guiding tool for a machining center according to the present invention can quickly align and install the worm, reduce the workload of maintenance personnel, improve the maintenance efficiency, and has the characteristics of convenient use and strong practicability.

[0026] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which will not affect the implementation effect of the present invention and the practicability of the patent.
