Abstract
The utility model discloses a kind of positioning and clamping mechanism automatically.Comprise collet chuck chuck, pull bar and revolution oil hydraulic cylinder, described collet chuck chuck is made up of collet chuck and collet chuck shell, by 30 degree of tapering positioning and lockings between collet chuck and collet chuck shell, described collet chuck end is provided with screw thread makes it be connected with pull bar one end, described pull bar is arranged in inner hole of spindle, and the pull bar other end is connected with revolution oil hydraulic cylinder.Be provided with positioning anchor in described collet chuck, make workpiece play location in put procedure, in described pull bar, be provided with annular backer, make workpiece ensure concentricity at position fixing process.The mobile transmission of revolution oil hydraulic cylinder piston is converted into the clamping of front end fixture or unclamps effect, its Stability Analysis of Structures, convenient disassembly.No matter clamping workpiece, clamp or unclamp, and need only just can realize by hand rotation reversal valve, and part is accurately located by positioning anchor and annular backer, substantially increases the stability of production efficiency and clamping power.
Description
Technical field
The utility model relates to a kind of fixture, especially a kind of positioning and clamping mechanism automatically.
Background technology
Automatic positioning and clamping mechanism fixture is in a lot of field extensive use.As the automatic hydraulic fixture of numerical control machining center, but in the application of bearing grinder industry or very few.Quality requirement but along with product parts is more and more higher, and some bearing producers also meet instructions for use at the corresponding frock clamp of import that adopts, and the frock clamp one of import is that input cost is higher, but the spare part production cycle of special consumable accessory is longer.
The clamping mode of this type of part all adopted hand-operated clamping in the past, this type of mode clamps and can produce location inaccurate (often operator can spend long time to correct part clamping, this working (machining) efficiency carrying out whole part is not high), and precision affects to some extent during part grinding, tighten by hand due to during clamping, clamping torque is unstable, cause repetitive positioning accuracy poor, while main shaft rotary course in gland get loose and easily cause security incident.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of positioning and clamping mechanism automatically, to improve the production efficiency of part.
The technical solution of the utility model is as follows:
A kind of positioning and clamping mechanism automatically comprises collet chuck chuck, pull bar and revolution oil hydraulic cylinder, described collet chuck chuck is made up of collet chuck and collet chuck shell, by 30 degree of tapering positioning and lockings between collet chuck and collet chuck shell, described collet chuck end is provided with screw thread makes it be connected with pull bar one end, described pull bar is arranged in inner hole of spindle, and the pull bar other end is connected with revolution oil hydraulic cylinder.
Be provided with positioning anchor in described collet chuck, make workpiece play location in put procedure, in described pull bar, be provided with annular backer, make workpiece ensure concentricity at position fixing process.
The beneficial effects of the utility model are, the mobile transmission of revolution oil hydraulic cylinder piston is converted into the clamping of front end fixture or unclamps effect, its Stability Analysis of Structures, convenient disassembly.No matter clamping workpiece, clamp or unclamp, and need only just can realize by hand rotation reversal valve, and part is accurately located by positioning anchor and annular backer, substantially increases the stability of production efficiency and clamping power.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of positioning and clamping mechanism automatically comprises collet chuck chuck, pull bar 7 and revolution oil hydraulic cylinder 8, described collet chuck chuck is made up of collet chuck 2 and collet chuck shell 1, by 30 degree of tapering positioning and lockings between collet chuck 2 and collet chuck shell 1, described collet chuck 2 end is provided with screw thread makes it be connected with pull bar 7 one end, described pull bar 7 is arranged in work spindle 5 endoporus, and pull bar 7 other end is connected with revolution oil hydraulic cylinder 8.
Location, positioning anchor 3(workpiece front end is provided with in described collet chuck), make workpiece 4 play location in put procedure, in described pull bar, be provided with annular backer 6(workpiece end location), make workpiece 4 ensure concentricity at position fixing process.
The operation principle of automatic positioning and clamping mechanism:
Collet chuck chuck is made up of collet chuck 2 and collet chuck shell 1, by 30 degree of tapering positioning and lockings between collet chuck 2 and collet chuck shell 1, one section of screw thread is had to make it be connected with pull bar at collet chuck end, again pull bar 7 is connected with revolution oil hydraulic cylinder 8 by turn round oil hydraulic cylinder to one individual mutually after pulling force, such collet chuck is just in locking state.Grinding part, in placement collet chuck, designs a positioning anchor (location, workpiece front end) and makes its workpiece 4 play location in put procedure in collet chuck, and in pull bar, the annular backer of bamboo product one (workpiece end location) makes its workpiece 4 ensure concentricity at position fixing process.After all location put in place, part is locked by revolution oil hydraulic cylinder, and main shaft starts rotation, grinding is carried out in the feeding of grinding spindle planker.To be ground complete after, workpiece locking is unclamped, then by manually being taken out by workpiece by revolution oil hydraulic cylinder.
Clamping workpiece flow process: in workpiece placement collet chuck, its workpiece is contacted in collet chuck completely and locate, after it contacts completely, starts revolution oil hydraulic cylinder and is locked by workpiece, provides after locking signal carry out grinding to workpiece again until revolution oil hydraulic cylinder.
