By installing a plurality of sets of different fixture assemblies which are used for machining the same workpiece on the operating platform according to the certain sequence, the different end surfaces of the same workpiece can be fixed on the operating platform, the machining center controls a tool to be positioned and rotate, different end surfaces of the same workpiece can be sequentially machined through the plurality of fixture assemblies, then the workpiece is sequentially moved forward to the next fixture assembly, finally the machined workpiece is taken out, a new workpiece is fixed on the first fixture assembly, the machining of different end surfaces of the same workpiece can be completed through the plurality of fixture assemblies, and a finished product is obtained after machining at the last fixture assembly is completed. The machining center operating platform has the advantages that the structure is simple, the operating platform is easy to manufacture, the structure of the operating platform is simplified, and the working efficiency of the machining center is improved.

Description

A kind of machining center operating platform

Technical field

The utility model belongs to machining center technical field, specifically, is a kind of machining center operating platform.

Background technology

Machining center is integrated numerical control system on common milling machine, can under the control of program code, more accurately carry out the lathe of Milling Process.Machining center has the function of milling machine, boring machine, drilling machine, makes operation high concentration, has greatly improved production efficiency.In addition, the speed of mainshaft of CNC milling machine and feed speed are all infinite variable speed, are therefore conducive to select optimized cutting consumption.

But the operating platform of traditional machining center is generally only fixed a workpiece, thereby drive workpiece rotation rotation to complete the processing of a plurality of end faces of workpiece by operating platform.

In aforesaid operations method, need to will after workpiece rotation, just can carry out the processing of other end faces, so the complex structure of operating platform, and need to wait for that operating platform drives the time of workpiece rotation, thereby wasted a large amount of time, reduced the operating efficiency of machining center.

By retrieval, the technological means that finds no effect solves the problems of the technologies described above.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, the machining center operating platform and the control method thereof that do not need rotational workpieces and can process a plurality of workpiece end faces are provided.

Scheme of the present utility model is achieved in that

A kind of machining center operating platform, it is characterized in that: on this operating platform, according to a definite sequence, a plurality of clamp assemblies are installed, the clamp assembly that described clamp assembly is the different end faces of fixing same workpiece, described clamp assembly is according to being arranged on clockwise on operating platform;

Described clamp assembly comprises rotation clamping support, bracing frame, hydraulic cylinder and framework, symmetrically arranged bracing frame is installed respectively on the operating platform at these left and right both ends of framework, this bracing frame is fitted together with the front end hinge of rotation clamping support, the rear end of this rotation clamping support connects a driving mechanism, by this driving mechanism, drive rotation clamping support to be rotated action, thereby workpiece can be fixed on operating platform.

And described driving mechanism is hydraulic cylinder or pneumatic cylinder.

Advantage of the present utility model and good effect are:

By the different clamp assemblies of many covers of the same workpiece of processing are installed according to this definite sequence on operating platform, therefore can on operating platform, be fixedly mounted with the different end face of identical workpiece simultaneously, machining center is controlled cutter positioning rotation, by a plurality of clamp assemblies, can process successively a plurality of different end face of same workpiece, and then workpiece is moved forward to next clamp assembly successively, the workpiece finally processing is taken out, and on the first clamp assembly, fix new workpiece, by a plurality of clamp assemblies, can complete the processing of the different end faces of same workpiece, after last clamp assembly completion of processing, be finished product.This operating platform does not need rotation, has simplified its structure, and has shortened process time, has improved operating efficiency; And by the action of Driven by Hydraulic Cylinder clamp assembly, workpiece firmly can be fixed on operating platform.The utility model is simple in structure, is easy to make, and has simplified the structure of operating desk, and has improved the operating efficiency of machining center.

Fig. 2 is the top view of Fig. 1;

Fig. 3 is I portion enlarged drawing in Fig. 1;

Fig. 4 is II portion enlarged drawing in Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail.

A kind of machining center operating platform, for example, a workpiece need to complete processing by four procedures, therefore, make respectively four groups of clamp assemblies, be that each group clamp assembly can complete manufacturing procedure one, and four groups of clamp assemblies are separately fixed on operating platform, as Fig. 1, shown in Fig. 2, the upper surface of this operating platform 1 is separately installed with the fixedly clamp assembly 8 of first operation, the fixing clamp assembly 5 of second operation work, fix the clamp assembly 6 and the clamp assembly 7 of fixing the 4th procedure of three process, each clamp assembly is one operational sequence of machining center, therefore can once process clockwise four procedures, as shown in the direction of arrow in Fig. 2, after completing, the 4th procedure is finished product.

In the present embodiment, what described clamp assembly 8 was realized is workpiece to be carried out to the fixture of horizontal direction clamping, as shown in Figure 3, comprise rotation clamping support 2, bracing frame 10, the framework 3 of hydraulic cylinder 9 and positioning workpieces (not shown), described framework is a rectangle frame body structure and is packed on operating platform, according to the difference of preprocessing Workpiece structure, its frame structure is not identical yet, this framework is left, symmetrically arranged bracing frame is installed respectively on the operating platform at right both ends, this bracing frame is fitted together with the front end hinge of rotation clamping support, the rear end of this rotation clamping support and the load of the tailpiece of the piston rod of hydraulic cylinder hinge are connected together, by Driven by Hydraulic Cylinder, rotate clamping support and be rotated action, thereby workpiece can be fixed on operating platform.

Described rotation clamping support also can drive its action by pneumatic cylinder.

Described clamp assembly 5 is similarly the fixture that horizontal direction clamps, and its structure is identical with clamp assembly 8, and just the frame structure of positioning workpieces is different, need determine according to the structure of workpiece, so no longer be described in detail in present patent application.

What described clamp assembly 7 was realized is workpiece to be carried out to the fixture of vertical clamping, as shown in Figure 4, comprise vertical clamping support 4, vertical bracing frame 12, hydraulic cylinder 13 and locating rack 11, described locating rack is packed on operating platform, this locating rack is determined according to the structure of workpiece, locating rack in the present embodiment accompanying drawing is rectangular configuration, on the operating platform of this locating rack one side, be fixed with symmetrically arranged vertical bracing frame, this vertical bracing frame is fitted together with the front end hinge of vertical clamping support, the rear end of this vertical clamping support and the load of the tailpiece of the piston rod of hydraulic cylinder hinge are connected together, by the vertical clamping support of Driven by Hydraulic Cylinder, be rotated action, thereby workpiece (not shown) can be fixed on operating platform.

Described vertically tight frame also can drive its action by pneumatic cylinder.
