Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; may be a mechanical connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
As shown in fig. 1 to 5, the anti-separation feed screw and nut seat comprises a feed screw 1, a feed screw nut 4, a nut seat 2 and a bolt in a shape like a Chinese character '7', wherein an external thread 301 is arranged at the tail end of the feed screw nut 3, the external thread 301 is matched with the nut, when the nut seat 2 is sleeved on the feed screw nut 3, the feed screw nut 3 passes through the nut seat 2, the feed screw nut 3 passes through the tail end of the nut seat 2 and is fixed by the bolt, and the anti-separation strength of the nut seat 2 and the feed screw nut 3 is enhanced. The nut seat 2 is provided with a fastening hole 5 and an auxiliary hole 4, the auxiliary hole 4 is in a long strip shape on the surface of the nut seat 2, the auxiliary hole 4 is provided with a fan-shaped channel 6 inside the nut seat 2, the fastening hole 5 is arranged at one end point of the fan-shaped channel 6, the auxiliary hole 4 is communicated with the fastening hole 5 inside the nut seat 2, and one end of the 7-shaped bolt is provided with a fastening nut 11. Specifically, the "7" style of calligraphy bolt includes: rotating head 8, dwang 9, fastening rod 10, fastening nut 11 is established in fastening rod 10 one end, fastening rod 10 is perpendicular with dwang 9, fastening nut 11's external diameter is greater than fastening rod 10 diameter. The purpose is, when fastening rod 10 rotated to preset position, when using fastening bolt fixed, the condition that "7" style of calligraphy bolt looseness rocked can not appear. The 7-shaped bolt is inserted from the auxiliary hole 4, after the bolt is inserted, the rotating head 8 is screwed, so that the whole bolt rotates by taking the rotating rod 9 as an axis, the fastening rod 10 rotates along the fan-shaped channel 6 at the bottom of the auxiliary hole 4 until the fastening nut 11 is matched with the fastening hole 5, and then the fastening bolt is used to penetrate into the fastening hole 5 to be matched and screwed with the fastening nut 11. The open position of the fastening hole 5 is matched with the through hole 7 on the screw rod nut 3. The spindle nut 3 can thus be fixed to the nut holder 2. The screwing direction of the internal thread of the fastening hole 5 is the same as the moving direction of the bolt in the shape of the Chinese character '7' in the fan-shaped channel 6. The design can avoid the phenomenon that the 7-shaped bolt retreats due to the rotation of the fastening bolt when the bolt is installed.
The specific working principle is as follows: when the nut seat is used, the nut seat 2 is firstly sleeved on the feed screw nut 3, the bolt is used for fixing the external thread at the tail end of the feed screw nut 3, the nut seat 2 is pre-fixed, then the bolt in the shape of the Chinese character '7' is inserted into the auxiliary hole 4 and rotates until the fastening nut 11 is matched with the fastening hole 5, and at the moment, the fastening hole 5 in the feed screw nut 3, the through hole in the nut seat 2 and the fastening nut are coaxially matched. And a fastening bolt penetrates through the feed screw nut 3, is inserted into the nut seat 2, and is finally screwed into the fastening nut 11 to complete the fastening action. When the lead screw during operation, screw-nut 3 moves along 1 direction of lead screw, and the pulling force direction that nut seat 2 bore is the dwang direction of "7" style of calligraphy bolt, because anchorage bar 10 is perpendicular with dwang 9, and the end of anchorage bar 10 is fastened the bolt fastening moreover, the condition that consequently the bolt is not hard up or withdraws from can not appear, solves because the problem that the lead screw-nut that the bolt sent to and lead to breaks away from with the nut seat, convenient operation, and the effect is showing.
