The slewing drive motor 7 、, the shaft 7 is directly driven by the drive motor 7 〇, and is worn. One end of the machine A is combined with a machining tool B. In order to avoid foreign matter such as turning liquid, dust and metal chips generated during machining, the rotatable material rod 5 may be invaded. The shaft seat 60 between the shafts further affects the smoothness and safety of the shaft 5, and generally, a dustproof device is disposed between the machining end of the shaft 50 and the shaft seat 6〇. 9. As shown in FIG. 4 and FIG. 5, the conventional dustproof device 90 includes an end cover 1 and a dustproof ridge 92 which are adjacent to each other and have a contoured shape; wherein the end cover 91 is screwed to the shaft seat. An open end of the 60, and abutting against the bearing 61 disposed on the shaft 5 〇 and the shaft seat 6 , the dust cover 92 is threadedly coupled to the shaft * , The dust cover 92 is recessed toward the end surface of the end cover 91 with a ring groove 921 for inserting the end cover 91. The specification of the ring groove 921 The system is slightly larger than the end M415010 盍91, and a small gap can be reserved between the end cover 91 and the dust cover 92, thereby preventing the end cover 91 and the dust cover 92 from interfering with each other to generate contact friction. Between the dust cover 92 and the end cover 91, only the core groove 921 is used to form a waterproof and dustproof mechanism for positive and convex matching. When the machining fluid is processed for a long time or a large amount, the turning fluid and the dust it carries can be used. It is also possible that there is a possibility of invading the inside of the shaft seat 6 ,, and it is difficult to provide an optimized waterproof and dustproof effect.
如果為了防水防塵考量，該端蓋9彳與防塵蓋9 $之間 的間隙應盡可能地縮小，但是受限於以下兩種因素，導致 该間隙難以有效地縮小：（一）為避免該軸桿5〇轉動時與該 軸座60發生干涉而影響轉動的順暢性，該間隙必須足夠 大；（二）避免切削顆粒等細小異物侵入該間隙而發生卡死現 象’（三）現有防塵裝置90係以車削加工成型所製成，精密 度欠到一定的限制。基於前述各項因素，現有的迷宮式防 塵裝置90設置於該端蓋91及該防塵蓋92端面方向之間的 間隙大約在0.15咖至〇.5麵的範圍左右，在一般的運轉實 施時，利用離心力及氣旋作用，還可以達到正常運轉及防 塵防水效果，但是當切削環境較惡劣時，你 例如·切削液的 水量過大或水壓過大或切削顆粒小於〇彳5 _時，現有防塵 裝置90就容易發生異物侵入現象而污染轴承，在戸、積到 定量後，便會發生軸承磨損失效及影響轉動順暢性^問題。 【新型内容】 為解決現有工具機主軸的防塵裝置在咏u 钍防水防塵設計的 4 M4nUl(j 不足及限制，本創作的主 水防塵效果之具防塵… “供—種能夠提高防 ^ Μ μ Μ - " •工具機主軸，本創作利用於端 规每防塵盍之間形成兩道 為丨，砂人μ — 碾凹凸巴配的迷宮式防水防塵機 φ】 配&對端盍與防塵^:祐丨ν 几 理，將端^防塵㈠防鏽及精密研磨等處 /、塵-在為面方向的裝配間隙最小化到〇 〇〇2 ΠΠΠ至0.01咖的範圍， „ Λ 另双杈问工具機主軸的防水防塵效 果，解決現有防塵裝置的限制與不足。If it is waterproof and dustproof, the gap between the end cover 9彳 and the dust cover 9 $ should be reduced as much as possible, but it is limited by the following two factors, which makes it difficult to effectively reduce the gap: (1) To avoid the axis When the rod 5 turns, it interferes with the shaft seat 60 to affect the smoothness of the rotation, and the gap must be sufficiently large; (2) avoiding the intrusion of fine foreign matter such as cutting particles into the gap and causing a jam phenomenon' (3) The existing dustproof device 90 It is made by turning and forming, and the precision is not limited. Based on the above various factors, the gap between the end face 91 and the end face of the dust cover 92 is about 0.15 to 5,000. In the general operation, The centrifugal force and cyclone action can also achieve normal operation and dustproof and waterproof effect. However, when the cutting environment is bad, if the water volume of the cutting fluid is too large or the water pressure is too large or the cutting particles are smaller than 〇彳5 _, the existing dustproof device 90 It is prone to foreign matter intrusion and contaminate the bearing. After the enthalpy and accumulation, the bearing wear failure and the smoothness of the rotation will occur.

The dust cover is provided with a second joint that fits over the first joint and is externally The surface is provided with a second hardened layer which is hardened and precision ground, and a gap is formed between the first joint portion and the second joint portion. In the tool machine main shaft, the first joint portion is formed with a first resistance ring and a second resistance ring, and is formed between the first and second resistance rings. a spacer, the first joint portion is disposed at a center of the first joint portion, and is disposed at a center of the circumference, and is provided with a first ring groove, a convex ring and a second ring groove, the first ring, the convex ring and The second ring 5 M415010 is inserted into the corresponding first ring groove, the groove and the second ring groove. In the machine tool main shaft, the first resistance ring and the second resistance ring are arranged in a p-level differential shape, and the outer side walls of the first resistance ring and the spacer are set to face outward. Wide sloped shape. The gap between the end cover and the dust cover in the direction of the end face of the machine tool spindle of the month 'j is 〇.〇〇2 coffee to 〇〇1 coffee, and is deleted from 〇〇〇3 to 〇〇〇5 coffee. good. The machine tool spindle, wherein the first hardened layer and the second hardened layer are subjected to surface hardening by a high-frequency hardening method, a carbon deposition method, a nitriding method or a subtractive method, and an electroplating chrome method or a chemical nickel method. , rust-proof treatment by soft nitriding method or organic bismuth coupling agent method. The machine tool spindle described above, wherein the first hardened layer and the second hardened layer are hardened layers having an anti-smashing function. The advantages and enhancements that can be obtained by the tool machine spindle with dust-proof device include: 1. The creation of two labyrinth-type waterproof and dustproof mechanisms between the end cover and the dust cover, with hardening and rust prevention. And precision grinding, etc., minimize the assembly gap between the end 盍 and the dust cover in the end direction to the range of 〇〇〇2 mm to 〇.01 _, which can greatly improve the waterproof and dustproof effect of the machine tool spindle. Smooth operation and safety. 2. The first ring groove and the resistance ring between the end cover and the dust cover are formed in a slanted shape 能够' to further waterproof the dustproof effect of the high machine tool spindle. 3. The two ring grooves and the resistance ring between the end cover and the dust cover are arranged in a step-like shape, which can further improve the waterproof and dustproof effect of the M415010 of the machine tool spindle. 4. After the end cover and dust cover of the creation are formed by turning, the hardened layer with increased hardness is formed on the surface after hard treatment, because the hardened layer is broken: it can break the invading foreign matter and cooperate with the rotation. Centrifugal force and gas knowing and discharging, there is #接#, the dust-proof device of the dust-proof device and the intrusion of foreign matter are equivalent. (4) After the turning and dust-proof cover created by Luben, the flatness of the surface of the end cover and the dust cover can be precisely controlled after the turning and molding, and the end cover and the dust cover of the present invention are formed after turning. After the prevention of 2%: the machine tool has not been used for a long time (for example: vacation or conversion work), and the shape is cheap and the adhesive is stuck, which improves the durability and practicability of the dustproof device.
