Utility model content
To solve the defect that prior art is present, the purpose of this utility model is to provide a kind of simple in construction, it is to avoid chip
The blind rivet finger setting fixture of the lathe of entrance.
The technical solution of the utility model is：A kind of blind rivet finger setting fixture of lathe, including clamp system, clamp system
Both sides are arranged with locating piece, and the clamp system includes being provided with anti-exfoliation device, briquetting between the briquetting being oppositely arranged, briquetting
It is connected with drive device, briquetting is provided with pressure rack, pressure rack surface is provided with blind rivet finger setting face, and the anti-exfoliation device includes and pressure
Frame be slidably connected and palette chip block, chip stop bottom connection back-moving spring, the glide direction of chip block with
The compaction direction of briquetting is vertical, and the pressure rack is circumferentially with to the anti-inclined lozenges in exfoliation device direction.
The detection hole passed through for detection liquid, the detection hole insertion locating piece, the detection hole are provided with the locating piece
By switching connection feed flow source.
The feed flow source is high pressure feed flow source.
The blind rivet finger setting face includes end face positioning and conical surface positioning.
The drive device is hydraulic cylinder.
The fixture is two, during work, and the blind rivet pin at workpiece bottom two ends is clamped respectively.
The blind rivet pin at workpiece bottom two ends, is the positioning datum of workpiece, is fixed on positioning bolt hole.
The beneficial effects of the utility model are：Blind rivet pin is assembled in the positioning bolt hole on workpiece, workpiece is used as
Positioning datum, the positioning that binding clasp clamps blind rivet to realize workpiece is clamped, simple and practical；It is internal when without piece-holder
The top that anti-exfoliation device is risen by spring reset, it is ensured that iron filings cannot be introduced into inside binding clasp, when there is piece-holder, i.e.,
Blind rivet pin enters binding clasp and depresses anti-exfoliation device, and binding clasp makes two side pressing blocks laterally be moved to center by hydraulic-driven, profit
Blind rivet is tensed downwards in the axial direction with lozenges, while utilizing the end face and the conical surface and the end face and the conical surface of binding clasp of blind rivet
Coordinate positioning, realize positioning clamping and synchronously complete.

Embodiment
1-4 is described further to the utility model below in conjunction with the accompanying drawings：
A kind of blind rivet finger setting fixture of lathe, including clamp system, clamp system both sides are arranged with locating piece 1, institute
State and be provided with anti-exfoliation device between the briquetting 3 that clamp system includes being oppositely arranged, briquetting 3, briquetting 3 is connected with drive device, is pressed
Block 3 be provided with pressure rack 4, the surface of pressure rack 4 be provided with blind rivet finger setting face, the anti-exfoliation device include be slidably connected with pressure rack 4 and
The chip block 5 of palette, the bottom of chip block 5 connection back-moving spring 6, the glide direction of chip block 5 and the pressure of briquetting 3
Tight direction is vertical, and the pressure rack 4 is circumferentially with to the inclined lozenges 7 in anti-exfoliation device direction.
The detection hole 2 passed through for detection liquid, the insertion locating piece 1 of detection hole 2, the inspection are provided with the locating piece 1
Gaging hole 2 is by switching connection feed flow source.
The feed flow source is high pressure feed flow source.
The blind rivet finger setting face includes end face positioning and conical surface positioning.
The drive device is hydraulic cylinder.
The fixture is two, during work, and the blind rivet pin at workpiece bottom two ends is clamped respectively.
The blind rivet pin at workpiece bottom two ends, is the positioning datum of workpiece, is fixed on positioning bolt hole.
Positioning method of the workpiece on fixture is a variety of, and the utility model discloses a kind of blind rivet pin positioning structure, if
Meter thought is the workpiece using machined completion locating surface and positioning bolt hole, and blind rivet pin is assembled on workpiece and is used as workpiece
A kind of positioning datum, the positioning for clamping blind rivet using special binding clasp to realize workpiece is clamped.This special binding clasp exists
During without piece-holder, internal anti-exfoliation device rises to top by spring reset, i.e. be brought into close contact with the inner peripheral surface of pressure rack 4, protects
Card iron filings cannot be introduced into inside binding clasp, when there is piece-holder, i.e., blind rivet pin enters the anti-exfoliation device of binding clasp pressure, clamps
