A positioning component 6 is arranged at one side part of the bottom plate 1, and the positioning component 6 comprises a storage box 601, a notch 602, a rotating shaft 603, a tape 604, a limiting disc 605 and an elastic rope 606;

receiver 601 is installed in the embedding of bottom plate 1 one side middle part, receiver 601 one side surface corresponds 1 one side position department of bottom plate and has seted up notch 602, the inside middle part of receiver 601 rotates and is connected with pivot 603, pivot 603 bottom is glued there is tape 604, the other end of tape 604 passes notch 602 and installs the iron sheet, avoid tape 604 to take in the condition that is difficult to take out in the receiver 601 completely, spacing dish 605 has all been cup jointed at corresponding tape 604 top position department in the middle part of the pivot 603 and top, pivot 603 top corresponds between two spacing dishes 605 position department and runs through installation elasticity rope 606, elasticity rope 606 both ends respectively with the inside relative both sides fixed surface connection of receiver 601, when making pivot 603 rotate, can drive elasticity rope 606 winding in the pivot 603 outside.

The working principle and the using process of the invention are as follows: when the machine tool positioning device convenient for assembly and fixation is installed, firstly, all the internal thread pipes 401 are rotated, so that two limiting plates 402 of the same internal thread pipe 401 are parallel to a T-shaped groove of a workbench, then the two limiting plates 402 at the bottom of the internal thread pipe 401 are placed into the T-shaped groove, then a tape 604 is pulled, the position data of a bottom plate 1 is obtained by attaching the end part of the tape 604 to the end part of the workbench, the tape 604 is ensured to be parallel to the side surface of the bottom plate 1 during measurement, errors caused by bending of the tape 604 are reduced, according to actual processing requirements, the position of the bottom plate 1 is adjusted until the data of the tape 604 is the data required for positioning, when the tape 604 is pulled out, the rotating shaft 603 is driven to rotate, the rotating shaft 603 rotates, so that the elastic rope 606 can be wound on the outer side of the rotating shaft 603, after the positioning data is obtained, the tape 604 is loosened, and when the elastic rope 606, the rotating shaft 603 is driven to rotate reversely, the tape 604 is collected into the storage box 601 to be stored, positioning is carried out when the tape is mounted on other machine tool workbenches next time, and meanwhile the limiting disc 605 can separate the tape 604 and the elastic rope 606 to ensure stable work of the tape 604 and the elastic rope 606;

after the position adjustment is finished, sequentially locking each locking assembly 4, when locking operation is performed on a single locking assembly 4, firstly rotating the internal thread tube 401 to enable two limiting plates 402 at the bottom of the internal thread tube 401 to be perpendicular to a T-shaped groove of a workbench, because the T-shaped groove of the workbench is inverted T-shaped, the two limiting plates 402 at the bottom of the internal thread tube 401 abut against the bottom of the inverted T-shaped groove, then rotating the bolt 404 clockwise, because the limiting plates 402 at the top of the internal thread tube 401 are blocked by the limiting columns 3, the internal thread tube 401 cannot synchronously rotate along with the bolt 404, therefore, under the action of threads, the bolt 404 moves downwards, after the bottom end of the bolt 404 is attached to the bottom end of the T-shaped groove of the workbench, the bolt 404 cannot continuously move downwards, so that the internal thread tube 401 can move upwards by continuously rotating the bolt 404, the rubber gasket 403 is arranged at the top end of the, the limiting plate 402 moves upwards along with the internal threaded pipe 401, so that the rubber gasket 403 is tightly attached to the inner wall of the inverted T-shaped bottom, the locking purpose is achieved, and meanwhile, the bolt 404 only needs to be rotated anticlockwise during disassembly;

after the bottom plate 1 is installed through the locking assembly 4, the installation cover 9 is rotated, the installation cover 9 rotates by taking the fixed disc 7 as an axis, the adjusting holes 8 are observed through the positioning holes 10, when the clamp 5 is at a proper angle, the adjusting holes 8 closest to the positioning holes 10 are selected at the moment and aligned with the positioning holes 10, then the positioning pins 11 are inserted into the positioning holes 10, the fixation of the installation cover 9 and the fixed disc 7 is completed, and the angle adjustment and the fixation of the clamp 5 are further completed.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
