Abstract
The present invention relates to a kind of frock clamp of adjustable eccentric, comprise eccentric adjustment mechanism, holding workpiece cylindrical mechanism and connector, described eccentric adjustment mechanism is arranged on the front end of connector, described holding workpiece cylindrical mechanism comprises top pawl, sleeve and back-moving spring, some described tops pawl is uniformly distributed the rear end that is arranged on connector hollow, between described top pawl and connector, back-moving spring is installed, described connector middle part has external screw thread, described sleeve interior surface has internal thread, and sleeve and connector are threaded connection. The adjusting range of eccentric throw of the present invention has expanded to 0-40mm, can clamp reliably the cylindrical of sizes. In addition,, because the design of eccentric adjustment mechanism adopts standard component in a large number, be convenient to batch production and processing.
Description
Technical field
The present invention relates to technical field of tooling clamps, particularly relate to a kind of frock clamp of adjustable eccentric.
Background technology
To adopt Special Eccentric collet head tool mostly for the processing of eccentric orfice at present, and such special fixture is only only applicable to the workpiece of specific dimensions, also have certain methods as eccentric in adopted cushion block to produce, the method need to regulate repeatedly, and workman's experience is had relatively high expectations and is not suitable for batch production. The fixture that patent 201210498004 relates to is only applicable to the eccentric throw adjustment within the scope of 0-2mm, is only suitable for the comparatively processing of precise part, for helpless compared with large eccentricity distance. Other mechanism is too complicated, high cost, and be not suitable for using in process.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of this invention is to provide a kind of frock clamp of adjustable eccentric. This fixture can expand to 0-40mm by the adjustment of eccentric throw, and can be under the condition by other instrument not, the cylindrical of clamping sizes.
For achieving the above object, the present invention adopts following technical scheme:
A kind of frock clamp of adjustable eccentric, comprise eccentric adjustment mechanism, holding workpiece cylindrical mechanism and connector, described eccentric adjustment mechanism is arranged on the front end of connector, described holding workpiece cylindrical mechanism comprises top pawl, sleeve and back-moving spring, some described tops pawl is uniformly distributed the rear end that is arranged on connector hollow, between described top pawl and connector, back-moving spring is installed, described connector middle part has external screw thread, described sleeve interior surface has internal thread, and sleeve and connector are threaded connection.
Described eccentric adjustment mechanism comprises lathe hold assembly, slide block, leading screw, leading screw back-up block, feed screw nut, line slideway; Described line slideway is fixed on connector, described some slide blocks are arranged on line slideway, two described leading screw back-up blocks are fixed on connector, described leading screw two ends are arranged on leading screw back-up block, described feed screw nut is arranged on leading screw, described lathe hold assembly is fixed by the first bolt and feed screw nut, and is connected with slide block by the second bolt; Described leading screw is with handle and scale, by turning handle, and described feed screw nut rectilinear motion, described lathe hold assembly moves with feed screw nut, makes described connector and lathe hold assembly produce relative displacement, is the eccentric throw of part to be processed.
Described sleeve rear end inner side is conical, and pawl upper surface, described top tilts, and inclined-plane matches with the taper shape of sleeve; When described sleeve travels forward, compress top pawl and firmly grasp workpiece; When described sleeve moves backward, under the effect of back-moving spring, loosen top pawl and unclamp workpiece.
Compared with prior art, the present invention has following outstanding substantive distinguishing features and significant advantage:
The adjusting range of eccentric throw of the present invention has expanded to 0-40mm, can clamp reliably the cylindrical of sizes. In addition,, because the design of eccentric adjustment mechanism adopts standard component in a large number, be convenient to batch production and processing.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are described further.
As shown in Figure 1, a kind of frock clamp of adjustable eccentric, comprise eccentric adjustment mechanism, holding workpiece cylindrical mechanism and connector 7, described eccentric adjustment mechanism is arranged on the front end of connector 7, described holding workpiece cylindrical mechanism comprises top pawl 8, sleeve 9 and back-moving spring 13, three described top pawls 8 are uniformly distributed the rear end that is arranged on connector 7 hollows, between described top pawl 8 and connector 7, back-moving spring 13 is installed, described connector 7 middle parts have external screw thread, described sleeve 9 inner surfaces have internal thread 12, and sleeve 9 is threaded connection with connector 7.
As shown in Figure 2, described eccentric adjustment mechanism comprises lathe hold assembly 1, slide block 2, leading screw 3, leading screw back-up block 4, feed screw nut 5, line slideway 6; Described line slideway 6 is fixed on connector 7, described four slide blocks 2 are arranged on line slideway 6, two described leading screw back-up blocks 4 are fixed on connector 7, described leading screw 3 two ends are arranged on leading screw back-up block 4, described feed screw nut 5 is arranged on leading screw 3, described lathe hold assembly 1 is fixing with feed screw nut 5 by the first bolt 11, and is connected with slide block 2 by the second bolt 10; Described leading screw 3 is with handle and scale, by turning handle, and described feed screw nut 5 rectilinear motions, described lathe hold assembly 1 moves with feed screw nut 5, makes described connector 7 and lathe hold assembly 1 produce relative displacement, is the eccentric throw of part to be processed. The adjusting range of eccentric throw, also can change flexibly by leading screw 3 and the line slideway 6 of selecting different length. In an embodiment, line slideway 6 length are 100mm, and effectively eccentric throw adjusting range is 40mm, degree of regulation 0.01mm.
As shown in Figure 3 and Figure 4, described sleeve 9 rear inside are conical, and pawl 8 upper surfaces in described top tilt, and inclined-plane matches with the taper shape of sleeve 9; When described sleeve 9 travels forward, compress promptly workpiece of top pawl 8; When described sleeve 9 moves backward, under the effect of back-moving spring 13, loosen top pawl 8 and unclamp workpiece.
