Abstract
A lead screw protection device for deep hole drilling and boring machine is provided. The device mainly solves the problems of damage of a lead screw and a nut and transmission precision loss caused by deformation of an existing lead screw under the effect of self-gravity. The device is characterized in that a rail clamp (1) is in a U-steel shape, a top plate (5) is arranged in one side of the rail clamp (1), a fastening bolt (6) is connected onto a lateral wall of the rail clamp (1) corresponding to the top plate (5) , an adjusting bolt (2) is connected to the other side of the rail clamp (1), a lead screw support (3) is connected with the lower end of the adjusting bolt (2), a lead screw support seat (4) is connected onto the lead screw support (3), and a semi-circular groove matched with the lead screw is arranged on the lead screw support seat (4). The lead screw protection device for the deep hole drilling and boring machine has the advantages of protecting the lead screw and preventing transmission precision loss and damage of the lead screw and the nut caused by deformation of the lead screw.
Description
Technical field
The utility model relates to a kind of lathe long screw, especially deep hole drilling and boring machine screw mandrel protective device.
Background technology
In field of machining, long screw mainly plays the feeding power transmitting effect.And existing screw mandrel is because length is longer, causes transmission accuracy to be lost and the loss of leading screw and screw being subjected to produce distortion under the self gravitation effect, so affects crudy and efficient.
Summary of the invention
Cause transmission accuracy to be lost and the problem of the loss of leading screw and screw being subjected to produce distortion under the self gravitation effect in order to solve existing screw mandrel.The utility model provides a kind of deep hole drilling and boring machine screw mandrel protective device.This deep hole drilling and boring machine screw mandrel protective device has the protection screw mandrel, prevents that screw mandrel from producing distortion and causing transmission accuracy to be lost and the characteristics of the loss of leading screw and screw.
The technical solution of the utility model is: this deep hole drilling and boring machine screw mandrel protective device comprises railway clamp, adjusts bolt, holder for screw rod and screw mandrel bracket.Railway clamp is channel steel shape, and a side is built-in with top board, is connected with fastening bolt on the railway clamp sidewall of corresponding top board, adjust bolt and be connected to railway clamp one side, holder for screw rod is connected to adjusts the bolt lower end, and the screw mandrel bracket is connected on the holder for screw rod, and the semicircle groove that matches with screw mandrel is arranged on the screw mandrel bracket.
The utlity model has following beneficial effect: this deep hole drilling and boring machine screw mandrel protective device is because the employing railway clamp is channel steel shape; one side is built-in with top board; be connected with fastening bolt on the railway clamp sidewall of corresponding top board; adjust bolt and be connected to railway clamp one side; holder for screw rod is connected to adjusts the bolt lower end; the screw mandrel bracket is connected on the holder for screw rod; the structure that the semicircle groove that matches with screw mandrel is arranged on the screw mandrel bracket; utilize railway clamp that this deep hole drilling and boring machine screw mandrel protective device is fixed on the machine tool guideway; the screw mandrel bracket is connected on the railway clamp by adjusting bolt and holder for screw rod; hold screw mandrel by the screw mandrel bracket; and then eliminate and to be subjected to screw mandrel to be subjected to the self gravitation effect to produce distortion, and cause transmission accuracy to be lost and the phenomenon generation of the loss of leading screw and screw.This deep hole drilling and boring machine screw mandrel protective device has the protection screw mandrel thus, prevents that screw mandrel from producing distortion and causing transmission accuracy to be lost and the characteristics of the loss of leading screw and screw.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
1-railway clamp among the figure, 2-adjusts bolt, 3-holder for screw rod, 4-screw mandrel bracket, 5-top board, 6-fastening bolt.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing, this deep hole drilling and boring machine screw mandrel protective device comprises railway clamp 1, adjusts bolt 2, holder for screw rod 3 and screw mandrel bracket 4.Railway clamp 1 forms channel steel shape by transverse slat two risers, one cant board is built-in with top board 5, be connected with fastening bolt 6 on railway clamp 1 sidewall of corresponding top board 6, fastening bolt 6 one side outside welds are connected to vertical piece, the pressing plate that is pressed on below the machine tool guideway is arranged under the vertical piece, pressing plate and vertical piece axially have through hole, the through hole that pressing plate and vertical piece are passed in adjustment bolt 2 upper ends is fixedly connected on railway clamp 1 one sides by nut, holder for screw rod 3 is connected to by nut and adjusts bolt 2 lower ends, screw mandrel bracket 4 is bolted on holder for screw rod 3, and the semicircle groove that matches with screw mandrel is arranged on the screw mandrel bracket 4.
During actual the use; railway clamp 1 is placed on the machine tool guideway; by fastening bolt 6 top board 5 is held out against in the machine tool guideway side again; again screw mandrel bracket 4 and the holder for screw rod 3 that installs is connected to adjustment bolt 2 lower ends; adjust screw mandrel bracket 4 height; make screw mandrel bracket 4 hold screw mandrel, namely finish screw mandrel protection operation.
