Abstract
A kind of machine tool element technical field is the utility model is related to, more specifically to a kind of clamping device of thin-walled parts.In existing thin-wall rotation-type part processing, it is clamped with magnetic chuck, multi-jaw chuck or expansion sleeve type fixture, in clamping process, part can be extruded necessarily.In process, since thin-walled parts wall thickness is thin, poor rigidity, it is vulnerable to the influence of the factors such as clamping, thermal deformation, it is difficult to ensure that the machining accuracy of workpiece.A kind of clamping device of thin-walled parts, base of the carrier head are equipped with multiple intermediate plates to clamp, and intermediate plate is equipped with multiple radially-arranged clamping beads, and bead is fixed on intermediate plate by axis pin and compression spring, and intermediate plate is equipped with aperture, and the diameter of aperture is less than the diameter of bead.Simple using this utility structure, easy to operate, clamping device is in contact with thin-wall part circular arc, therefore will not produce damage to the finished surface of thin-wall part, and can improve the distribution of force at piece-holder end, ensures machining accuracy and quality.
Description
Technical field
This practicality is related to a kind of machine tool element technical field, and the clamping more specifically to a kind of thin-walled parts fills
Put.
Background technology
In existing thin-wall rotation-type part processing, it is first used to magnetic chuck, multi-jaw chuck or expansion sleeve type fixture by thin-walled
From being simultaneously clamped, the cutter then processed is processed part according to processing request slewing parts, in clamping mistake
Cheng Zhong, to ensure that process keeps enough rigidity, part can be extruded necessarily.In process, due to thin-walled zero
Part wall thickness is thin, poor rigidity, is vulnerable to the influence of the factors such as clamping, gravity, vibration and thermal deformation caused by cutting, it is difficult to protect
Demonstrate,prove the machining accuracy and requirement of workpiece.
Utility model content
A kind of deficiency of this practical purpose aiming at the prior art, there is provided folder for thin-wall rotation-type part processing
Tight device, the defects of solving easily to be deformed in existing fixture processing, influence processing quality.
A kind of clamping device of thin-walled parts, including base of the carrier head, the base of the carrier head are equipped with multiple folders to clamp
Piece, the intermediate plate are equipped with multiple radially-arranged clamping beads, and the bead is fixed on intermediate plate by axis pin and compression spring
On, the intermediate plate is equipped with aperture, and the diameter of the aperture is less than the diameter of bead.
As further improving and supplementing to such scheme, this practicality further includes following additional technical feature：
The material of the bead is rubber, and part will not be caused to damage.
Bead on the intermediate plate has two rows, adds clamping force.
The axis pin is equipped with Hexagon hole, installs and easy to adjust.
It can reach following beneficial effect using the utility model：The utility model is simple in structure, easy to operate, economical real
With, since clamping device is in contact with thin-wall part circular arc, therefore damage will not be produced to the finished surface of thin-walled cylindrical workpiece, and energy
Improve the distribution of force at piece-holder end, thin-walled cylindrical workpiece outer wall stress deformation will not be made, ensure machining accuracy and quality.
Brief description of the drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the top view of the utility model.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, the utility model is a kind of clamping device of thin-walled parts.
The clamping device of thin-walled parts described in the present embodiment, including base of the carrier head 1, the base of the carrier head 1 are equipped with multiple
To the intermediate plate 2 clamped, the intermediate plate 2 is with 3,4,6,8 circumference uniform distributions, and the present embodiment is 6, each intermediate plate 2
At least one radially-arranged clamping bead 5 is equipped with, the bead 5 is fixed on intermediate plate 2 by axis pin 3 and compression spring 4,
Axis pin 3 is threadedly coupled with intermediate plate 2, extrudes compression spring 4 by axis pin 3, bead 5 is fixed and positioned, and is set on the intermediate plate 2
There is aperture 21, the diameter of the aperture 21 is less than the diameter of bead 5, and 5 part of bead can be pierced by aperture 21, according to the zero of clamping
Part 6 is different, and the distance that 5 part of bead is pierced by aperture 21 is also different.
Further, the material of the bead 5 is rubber.
Further, the bead 5 on the intermediate plate 2 has two rows.
Further, the axis pin 3 is equipped with Hexagon hole.
When the clamping device of this thin-walled parts is in use, 6 one end of part is resisted against on backer 7, the positioning of height is carried out,
By adjusting upper-lower position of the axis pin 3 in intermediate plate 2, bead 5 is set slightly to stretch out intermediate plate 2, base of the carrier head 1 is connected by other correlated parts
It is connected on power source, when intermediate plate 2 is clamped, bead 5 inside contracts, and part 6 is clamped, because bead 5 and 6 circular arc of part clamp, stress
Small, the deformation of generation can be ignored, and because bead 5 is upper and lower twice, clamping force is enough with Clamp blocks 6, process
It is solid and reliable, quality assurance.
It is the preferred embodiment of the utility model above, the scope of protection of the utility model is not limited, for ability
The deformation and improvement that field technique personnel mentality of designing according to the present utility model is made, should all be considered as the protection of the utility model
Within the scope of.
