Description

Easily-disassembled and assembled screw base

Technical Field

The utility model relates to an easy dismouting screw rod base for tube-shape structure processing belongs to machining technical field.

Background

Aiming at the tubular structural members produced in batch, the screw rod needs to be frequently disassembled and assembled for part processing, the traditional scheme is that a T-shaped nut is arranged in a T-shaped groove of a working table surface of a machine tool, the screw rod is screwed into the T-shaped nut, and the T-shaped nut is matched with the T-shaped groove of the machine tool and the nut is screwed up to play roles in positioning and clamping. After the parts are machined, the parts can be disassembled only after the nuts are completely screwed out of the T-shaped grooves. If parts are needed to be machined urgently, the screw rod needs to be repeatedly installed and removed, the process occupies the time of the machine tool, the dismounting operation is labor-consuming, and the product manufacturing efficiency is influenced. Therefore, an easily detachable screw base is urgently needed to realize quick assembly and disassembly and save the period.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem existing in the prior art and providing an easy dismounting screw base that can quick assembly disassembly and cycle are short.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an easy dismouting screw rod base, the lower extreme of base is T type structure for cooperate with the T type groove of lathe table surface, the upper end be T type groove breach, be used for with T type nut cooperation.

Preferably, the T-shaped groove notch is in clearance fit with the T-shaped nut.

Preferably, the T-shaped structure is coaxial with the T-shaped groove notch.

Preferably, the base is of an integrated structure.

The screw base easy to disassemble and assemble is designed to be a double-T-shaped structure, and the lower end T-shaped structure is matched with a T-shaped groove of a machine tool working table top and used for being fixed with the machine tool table top; the upper end is provided with a T-shaped groove notch which is in clearance fit with the T-shaped nut, so that the T-shaped nut can be smoothly installed and removed from the T-shaped groove notch. In the batch part production process, easy dismouting screw rod base is fixed at the T type inslot on the lathe workstation, and the screw rod is connected with T type nut, when the renewal part, only need slightly loosen the screw rod, with T type nut from T type notch take out can, when the installation part, only need with T type nut high-speed fit to T type notch, screw up the screw rod can, realize the quick assembly disassembly of screw rod.

Compared with the prior art, the utility model has the advantages of as follows: the quick positioning and clamping of the cylindrical structural member can be realized, the production efficiency is improved in the production process of the batch structural members, and the installation labor intensity is reduced.

Drawings

FIG. 1 is a schematic structural diagram of an embodiment of the present invention;

FIG. 2 illustrates a screw and T-nut used in an embodiment of the present invention;

fig. 3 is a schematic view of the use of an embodiment of the invention;

in the figure, 1, a screw base is easy to disassemble and assemble; 2. a T-shaped nut; 3. a screw; 4. a workpiece; 5. pressing a plate; 6. a machine tool table surface; 7. t-shaped groove.

Detailed Description

It should be noted that, in the present embodiment, the directional words "upper" and "lower" are all described according to the drawings, and do not limit the present invention.

The present invention will be described in further detail with reference to the accompanying drawings 1-3: as shown in figure 1, an easily detachable screw base 1 is designed into an integrated double-T-shaped structure, the lower end T-shaped structure is matched with a T-shaped groove 7 of a machine tool working table top and used for being fixed with the machine tool table top, a T-shaped groove notch is designed at the upper end of the structure and is in clearance fit with a T-shaped nut 2, and the T-shaped nut 2 can be smoothly installed and detached from the T-shaped groove notch.

The specific implementation steps are as follows:

step 1: the screw base 1 easy to disassemble and assemble is installed in a T-shaped groove 7 of a machine tool working table surface 6, so that the positioning with a machine tool is realized;

step 2: the screw rod 3 passes through a hole on the pressing plate 5, and the lower end of the screw rod 3 is connected with the T-shaped nut 2 through threads;

and step 3: the T-shaped nut 2 is installed in a T-shaped groove notch on the screw base 1 easy to disassemble and assemble, the pressing plate 5 presses the workpiece 4, the screw 3 is screwed tightly, and positioning and clamping of the workpiece 4 are achieved. Because T type groove breach and T type nut 2 are clearance fit, consequently can realize quick installation.

And 4, step 4: and after the workpiece 4 is machined, slightly loosening the screw rod 3, and taking the T-shaped nut 2 out of the notch of the T-shaped groove to finish the disassembly of the part.

When the workpieces 4 are continuously produced, the workpieces 4 can be quickly disassembled and assembled by repeating the steps 2 to 4.

Above-mentioned embodiment is only the utility model discloses a preferred embodiment, the structure of easy dismouting screw rod base 1 upper end can be adjusted according to production needs, as long as satisfy can be quick, install smoothly and demolish can.
