Often need to increase float support and compress point, if supported using traditional regulation and mobile presser device, not only clamping time
It is long, and support and compress unreliable, easily cause workpiece to deform, influence processing efficiency and machining accuracy.Therefore, pressed from both sides in frock
, it is necessary to develop a kind of float support and hold-down gear of special holding workpiece in tool application.Therefore, we are in long-term work
In practice, a kind of float support and hold-down gear are developed, achieve good effect.
Utility model content
The purpose of this utility model is to provide a kind of float support and hold-down gear, it is to avoid because the workpiece that clamping causes becomes
Shape, preferably realizes fixation of the work in-process to workpiece.
To realize as above purpose, the technical solution adopted in the utility model is：A kind of float support and hold-down gear, including
Pressing plate, sphere band shoulder nut, taper faced washer, spring, regulation support, hexagon thin nut, float support, conehead screw rod, anti-rotation circle
Pin, bearing, chuck body and guide cylinder pin；Large and small two holes being parallel to each other are provided with bearing, bearing is arranged on folder
On tool body, float support end portion is arranged to be provided with the female cone thin-wall sleeve of four grades point groove, float support upper part
It is arranged to fan-shaped plank frame, its side is provided with a small bullport, on the external cylindrical surface and bearing of float support lower end
Macropore is slidably matched, and lower end internal conical surface and the conehead screw rod male cone (strobilus masculinus) of float support are slidably matched, and pressing plate is sleeved on conehead spiral shell
On bar, spring is provided between pressing plate and float support.
Aperture and the tight fit of guide cylinder pin end portion, guide cylinder pin upper part and float support on bearing
On small bullport gap coordinate, be provided with float support regulation support and hexagon thin nut.
Conehead screw tip is provided with sphere band shoulder nut, taper faced washer, and bottom is provided with anti-rotation straight pin, anti-rotation cylinder
Pin two ends and float support bottom etc. divide a groove to be slidably matched.
Elongated slot is provided with pressing plate, pressing plate can be along conehead screw rod, regulation support direction displacement.
Due to using technical scheme as described above, the utility model has following superiority：The utility model structure is tight
Gather, operate nimble, formed similar to collet structure by float support, conehead screw rod, by float support tensioner in branch
In seat macropore, and with pressing plate workpiece pressing, it is to avoid clamping workpiece deformation, improve clamping efficiency.
Brief description of the drawings
Fig. 1 is the cross-sectional view of a kind of float support of the utility model and hold-down gear.
Fig. 2 is the overlooking the structure diagram of Fig. 1.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.As shown in figure 1, a kind of float support and compression dress
Put, including：Including pressing plate 2, sphere band shoulder nut 3, taper faced washer 4, spring 5, regulation support 6, hexagon thin nut 7, branch of floating
Support 8, conehead screw rod 9, anti-rotation straight pin 10, bearing 11, chuck body 12 and guide cylinder pin 13.
Large and small two holes being parallel to each other are machined with bearing 11, the end portion of float support 8 is arranged to be provided with four etc.
Divide the female cone thin-wall sleeve of groove, the upper part of float support 8 is arranged to fan-shaped plank frame, and there is a small bullport its side,
The external cylindrical surface of the lower end of float support 8 is slidably matched with the macropore of bearing 11, lower end internal conical surface and the conehead spiral shell of float support 8
The male cone (strobilus masculinus) of bar 9 is slidably matched.Pressing plate 2 is sleeved on conehead screw rod 9, and spring 5 is provided between pressing plate 2 and float support 8.
The aperture tight fit of the end portion of guide cylinder pin 13 and bearing 11, the upper part of guide cylinder pin 13 and floating
The small bullport gap of support 8 coordinates, and float support 8 drives regulation branch in the case where the macropore of bearing 11 and guide cylinder pin 13 are limited
Support 6 and hexagon thin nut 7 can only move up and down.
The top of conehead screw rod 9 is provided with sphere band shoulder nut 3, taper faced washer 4, and bottom is provided with anti-rotation straight pin 10, prevents
Turn point groove such as the two ends of straight pin 10 and the bottom of float support 8 to be slidably matched.Conehead screw rod 9 can only move up and down.
