Technical Field

The invention relates to the technical field of machine tool machining equipment, in particular to a novel indexing type numerical control machine tool structure.

Background

According to the design complexity and the product batch performance of the existing industrial requirement special industry, machine tool parts with different performances are designed for different products to be conveniently and effectively processed. When a part is installed, the traditional machine tool is often matched by multiple persons, and after the installation is finished, the adjustment is required for multiple times, and for parts needing special angle use, the angle adjustment cannot be easily carried out, so that the use has great limitation.

Therefore, the existing machine tool mechanism needs to be correspondingly improved, the characteristics of saving time, increasing yield and reducing labor are achieved, the time for manually installing workpieces is greatly saved through the design, the batch processing can be realized through one-time clamping, and the secondary positioning is not needed.

Disclosure of Invention

The present invention is directed to a novel indexing type numerical control machine tool structure, so as to solve the problems mentioned in the above background art.

In order to achieve the purpose, the invention provides the following technical scheme: the novel indexing numerical control machine tool structure comprises a fixing plate, an indexing table, a servo motor and a speed reducer; the speed reducer is fixedly installed on the upper surface of the fixing plate, the servo motor is arranged on the upper portion of the front side of the speed reducer, the rotation speed of the speed reducer is started and controlled through the servo motor, and then the rotation speed of the machine tool during working is controlled. The left side output of speed reducer rotates and is connected with the transmission shaft, and the terminal fixed mounting of transmission shaft has the chuck, and the left side limit portion of chuck is equidistant all around to be provided with four groups of the same buckles, can be with the inside of waiting the one end joint to the chuck of the work piece of processing through the buckle, and then rotate through the rotatory transmission shaft that drives of speed reducer, then carry out rotary machining through chuck drive work piece again. A set of indexing table is detachably installed downwards on the front side and the rear side of the fixing plate through screws, a semicircular structure is arranged at the bottom of the indexing table, an indexing table base of an arch structure is arranged on the lower side of the indexing table, and the top of the indexing table base is matched with the semicircular structure at the bottom of the indexing table. Slide rails are fixedly arranged on the upper portions of the front side and the rear side of the indexing table base, a limiting opening is formed in the slide rails, a slide block is fixedly mounted on the lower side of the indexing table corresponding to the limiting opening, and the slide block is connected in the limiting opening in a sliding mode and is matched with the limiting opening in a sliding mode to limit the sliding distance of the indexing table on the indexing table base. The top middle part of dividing table base upwards fixed mounting has the worm wheel of a set of arc structure, and threaded connection has four sets of worms that set up middle part downside in the dividing table on the worm wheel, and the right-hand member portion fixedly connected with rocker of worm moves on the worm wheel through the manually-rotated rocker drive worm, and then drives the dividing table and moves about along the arc on the dividing table base, and then adjusts the processing angle of the work piece of the side left part of dividing table.

As a further scheme of the invention: the bottom of the indexing table base is supported by an indexing table fixing plate in a rectangular structure.

As a further scheme of the invention: the middle part of transmission shaft supports through the axle supporting seat, and the bottom fixed mounting of axle supporting seat can improve the equilibrium of the transmission shaft left and right sides at the upper surface of fixed plate, the setting of axle supporting seat, prevents that the atress is uneven to take place the slope.

As a further scheme of the invention: the chuck is set to be a cylindrical structure with an opening at the left side.

As a further scheme of the invention: the internal surface of chuck is provided with the arch that is used for improving frictional force between work piece and the chuck inboard, improves the stability of work piece joint in the chuck.

As a further scheme of the invention: the upper surface of the front side of the fixed plate of the dividing table is fixedly provided with a control switch for controlling the whole machine tool structure to operate. Four groups of stabilizing blocks for improving the stability of the bottom of the fixed plate of the indexing table are fixedly arranged on the lower surface of the bottom of the fixed plate of the indexing table.

As a still further scheme of the invention: radiating holes are formed in the front side wall and the rear side wall of the speed reducer, and the radiating holes are used for improving the ventilation and heat dissipation capacity inside the speed reducer. A plurality of groups of ventilation holes are annularly formed in the right side face of the chuck and are used for improving the ventilation effect inside the chuck.

Compared with the prior art, the invention has the beneficial effects that: by arranging the chuck, the part to be processed can be clamped in place at one time, and the installation is stable; the worm is driven to rotate on the worm wheel by manually rotating the rocker, and then the indexing table moves left and right on the indexing table base, so that the angle of the workpiece is adjusted, and the workpiece with different angles can be conveniently machined, manufactured and used; the part bed adopts multi-part integration, is flexible and convenient to manufacture and has stronger stability; the time for manually installing the workpiece is greatly saved through the design, the workpiece can be machined in batches by one-time clamping, and secondary positioning is not needed; through setting up manual control's angular adjustment, very big improvement the suitability of this mechanism.
