Description
Technical Field
The utility model relates to the field of machinary, specifically indicate to have a lead screw protection device suitable for digit control machine tool.
Background
The numerically controlled lathe is one of the widely used numerically controlled machines at present. The cutting tool is mainly used for cutting and processing inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces with any taper angles, complex rotary inner and outer curved surfaces, cylindrical threads, conical threads and the like, and can perform grooving, drilling, reaming, boring and the like.
The lead screw on the numerical control lathe can bear great pressure when the part is processed usually, in order not to let the lead screw warp, can connect lead screw protection mechanism in the workstation below usually, but traditional lead screw protection mechanism often produces the condition of mechanical wear to the lead screw itself when the workstation round trip movement easily, leads to the lead screw precision to descend, hinders the removal production of workstation even.
The utility model discloses a lead screw protection device suitable for digit control machine tool is to the problem design that foretell prior art exists the utility model discloses the purpose of research.
SUMMERY OF THE UTILITY MODEL
To the problem that above-mentioned prior art exists, the utility model provides a lead screw protection device suitable for digit control machine tool can effectively solve the problem that above-mentioned prior art exists.
The technical scheme of the utility model is that:
a lead screw protection device suitable for a numerical control machine tool comprises a machine body and a lead screw arranged on the machine body, wherein a workbench capable of moving back and forth along the direction of the lead screw is arranged on the lead screw, and the lead screw is driven by a corresponding motor; guide rails are arranged below the screw rods in parallel, and at least 1 screw rod protection mechanism can be movably arranged on the guide rails; the screw rod protection mechanism comprises a screw rod bracket, a bracket seat and a base which are sequentially connected from top to bottom, and the base is movably arranged on the guide rail; the screw rod bracket and the screw rod are arranged in a clearance mode, and a positioning pin and a spring are arranged between the screw rod bracket and the bracket seat; one side rigid coupling of base has the connecting plate, the connecting plate upper half is the U type and top rigid coupling in workstation.
And the bracket seat is provided with a groove for mounting the screw rod bracket.
And the connecting plate is provided with a threaded hole matched and locked to the workbench.
The utility model has the advantages that:
when the workbench of the utility model moves, the lead screw protection mechanism can move synchronously with the workbench through the connecting plate, and when the workbench moves normally, a gap is arranged between the lead screw bracket and the lead screw, so that the lead screw bracket is prevented from blocking the rotation of the lead screw; when the workbench is used for drilling and other operations, the lead screw is bent downwards due to the large stress of the workbench, and the lead screw bracket can effectively support the lead screw to prevent the lead screw from further deforming; and even if the workbench needs to be moved while drilling, the influence on the rotation of the screw rod can be reduced as much as possible under the action of the spring. The utility model is not only simple in structure, play effectual protection effect to the lead screw moreover.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an exploded view of the components of the lead screw protection mechanism.
Detailed Description
To facilitate understanding of those skilled in the art, the structure of the present invention will now be described in further detail with reference to the following examples:
referring to fig. 1-2, a lead screw protection device suitable for a numerical control machine tool comprises a machine body 1 and a lead screw 2 arranged on the machine body 1, wherein a workbench 3 capable of moving back and forth along the direction of the lead screw 2 is arranged on the lead screw 2, and the lead screw 2 is driven by a corresponding motor 4; a guide rail 5 is arranged below the screw rod 2 in parallel, and at least 1 screw rod protection mechanism 6 can be movably arranged on the guide rail 5; the screw rod protection mechanism 6 comprises a screw rod bracket 7, a bracket seat 8 and a base 9 which are sequentially connected from top to bottom, and the base 9 can be movably arranged on the guide rail 5; a gap is formed between the screw rod bracket 7 and the screw rod 2, and a positioning pin 10 and a spring 11 are arranged between the screw rod bracket 7 and the bracket seat 8; one side rigid coupling of base 9 has connecting plate 12, connecting plate 12 upper half is the U type and top rigid coupling in workstation 3.
The bracket seat 8 is provided with a groove 13 for installing the screw rod bracket 7.
The connecting plate 12 is provided with a threaded hole 14 which is matched and locked to the workbench 3.
When the workbench 3 of the utility model moves, the screw rod protection mechanism 6 can move synchronously with the workbench 3 through the connecting plate 12, and when the workbench moves normally, a gap is kept between the screw rod bracket 7 and the screw rod 2, so that the screw rod bracket 7 is prevented from blocking the rotation of the screw rod 2; when the workbench 3 is drilled and other operations, the lead screw 2 bends downwards due to the large stress of the workbench 3, the lead screw bracket 7 can effectively support the lead screw 2 to prevent the lead screw from further deformation; even if the workbench 3 needs to be moved while drilling, the influence on the rotation of the screw rod 2 can be reduced as much as possible by the action of the spring 11.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made within the scope of the claims of the present invention should belong to the scope of the present invention.
