A sealing and waterproof mechanism for the output end of an angle head

Abstract

This utility model relates to the field of sealing and waterproofing technology for the output end of an angle head, and particularly to a sealing and waterproofing mechanism for the output end of an angle head. The sealing assembly includes an embedded sealing cover, which is installed on the output end of the angle head. A boss is fixedly installed on one side of the embedded sealing cover, and an oil seal is provided on the inner wall of the boss. This utility model forms a double-sealing design through the combined use of the embedded sealing cover and the oil seal. The embedded sealing cover is pressed tightly against the output end of the angle head by its end face, and the sealant effectively prevents external cutting fluid, oil, and metal shavings from entering along the contact surface between the sealing cover and the output end of the angle head, and the gap between the sealing cover boss and the bearing hole. The oil seal further prevents splashed liquid from seeping into the interior along the output shaft. This double protection significantly improves the sealing reliability, thereby preventing the intrusion of external contaminants and avoiding bearing contamination.

Description

Technical Field

[0001] This utility model belongs to the field of sealing and waterproofing technology for the output end of an angle head, and specifically relates to a sealing and waterproofing mechanism for the output end of an angle head. Background Technology

[0002] In the field of machine tool processing, the angle head is a key component for achieving multi-faceted and multi-angle machining. The sealing and waterproofing performance of its output end directly affects the overall machining accuracy and the service life of the equipment. Currently, the output end of the machine tool angle head is often in harsh working conditions where it is directly flushed by cutting fluid because it needs to hold the cutting tool for cutting operations. This area contains a large amount of cutting fluid residue, oil, metal shavings, and other contaminants.

[0003] Existing angle head output end sealing structures typically use an external cover plate to seal the angle head output end. The mating surface between the cover plate and the angle head housing is prone to gaps due to assembly errors or long-term vibration, causing external residual liquids, oil stains, etc. to seep into the internal bearing area through the gaps and contaminate the bearing.

[0004] Therefore, we need to propose a sealing and waterproof mechanism for the output end of the angle head to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing and waterproof mechanism for the output end of an angle head. By setting an embedded sealing cover and an oil seal, it can effectively prevent oil and residual liquid from entering the inner wall of the output end of the angle head, thereby avoiding contamination of the bearing and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing and waterproof mechanism for the output end of an angle head, comprising an angle head output end, wherein a sealing component is installed on the angle head output end;

[0007] The sealing assembly includes an embedded sealing cap, which is installed on the output end of the angle head. A boss is fixedly installed on one side of the embedded sealing cap, and an oil seal is provided on the inner wall of the boss.

[0008] Furthermore, the oil seal is a double-lip skeleton oil seal, and the oil seal lip is provided with a dustproof lip.

[0009] Furthermore, an installation groove is provided on the output end of the angle head, the installation groove is fitted with the end face of the embedded sealing cover, and a sealant is provided between the installation groove and the embedded sealing cover.

[0010] Furthermore, a bearing hole is provided in the mounting groove, and the bearing hole is used in conjunction with the boss.

[0011] Furthermore, a bearing is fixedly installed in the bearing hole, and an output shaft is rotatably connected inside the bearing. The output shaft is used in conjunction with an oil seal.

[0012] Furthermore, the mounting groove has multiple sets of threaded grooves, and the embedded sealing cover has multiple sets of threaded holes. The embedded sealing cover is detachably mounted on the mounting groove by bolts, and the multiple sets of bolts are evenly distributed along the axial direction of the embedded sealing cover.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes an embedded sealing cap and an oil seal to create a double-sealing design. The embedded sealing cap presses tightly against the output end of the angle head, and the sealant effectively prevents external cutting fluid, oil, and metal shavings from entering through the contact surface between the sealing cap and the output end of the angle head, as well as the gap between the sealing cap boss and the bearing hole. The oil seal further prevents splashed liquid from seeping into the interior along the output shaft. This double protection significantly improves sealing reliability, thereby preventing external contaminants from entering and avoiding bearing contamination. Attached Figure Description

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A sealing and waterproof mechanism for the output end of an angle head.

[0024] It includes an angle head output end 100, on which a sealing component 200 is installed;

[0025] The sealing assembly 200 includes an embedded sealing cover 210, which is installed on the angle head output end 100. A boss 220 is fixedly installed on one side of the embedded sealing cover 210, and an oil seal 230 is provided on the inner wall of the boss 220.

[0026] The boss 220 is an annular boss, and the boss 220 and the embedded sealing cover 210 are integrally formed. There is a fit tolerance between the boss 220 and the bearing 130 to ensure the positioning accuracy between the embedded sealing cover 210 and the bearing hole 120 and reduce the change in fit clearance caused by vibration.

[0027] The oil seal 230 is a double-lip skeleton oil seal, and the lip of the oil seal 230 is provided with a dustproof lip.

[0028] The inner ring of the oil seal 230 fits tightly against the outer side of the output shaft 140 to form a radial seal, preventing splashed cutting fluid and oil from seeping into the angle head output end 100 along the output shaft 140. The oil seal 230 is made of nitrile rubber or fluororubber.

[0029] An installation groove 110 is provided on the output end 100 of the angle head. The installation groove 110 is in contact with the end face of the embedded sealing cover 210, and a sealant is provided between the installation groove 110 and the embedded sealing cover 210.

[0030] The mounting groove 110 has a planar structure, and the embedded sealing cover 210 fits flush with the plane of the mounting groove 110. Sealant is applied between the mounting groove 110 and the embedded sealing cover 210 to fill the gap between them, preventing external residual liquid from entering the angle head output shaft 140 and avoiding contamination of the bearing 130. The sealant is a high-temperature resistant and cutting fluid-resistant silicone sealant or polyurethane sealant.

[0031] The mounting groove 110 is provided with a bearing hole 120, which is used in conjunction with the boss 220.

[0032] A bearing 130 is fixedly installed in the bearing hole 120, and an output shaft 140 is rotatably connected in the bearing 130. The output shaft 140 is used in a sealing cooperation with an oil seal 230.

[0033] The mounting groove 110 has multiple sets of threaded grooves 330, and the embedded sealing cover 210 has multiple sets of threaded holes 320. The embedded sealing cover 210 is detachably mounted on the mounting groove 110 by bolts 310, and the multiple sets of bolts 310 are evenly distributed along the axial direction of the embedded sealing cover 210.

[0034] Bolt 310 is an internal hexagonal head bolt with a specification of M6-M12. The corresponding specification is selected according to the outer diameter of the embedded sealing cover 210 to ensure that the embedded sealing cover 210 is pressed tightly against the mounting groove 110, avoiding vibration that could cause the bolt 310 to loosen, thereby ensuring the sealing effect of the sealant.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
