Abstract
The utility model discloses a spring roll ball type top apex device which comprises a top apex body, a top apex head, a pulling claw, a spring, a spring seat and a steel ball. The top apex head and the pulling claw are arranged on the same end of the top apex body and are connected with the top apex body in a sliding mode. A cavity is arranged at one end where the top apex body is close to the top apex head, the steel ball is arranged in the cavity, the spring seat is arranged at the bottom end of the cavity, and the spring is fixed on the lower portion of the spring seat. Through the adoption of the technical scheme, workpieces can be machined at a time, and at the same time, a machine is not needed to be stopped for clamping the workpieces, operation is simple and convenient, and machining efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of Finial device, particularly relates to a kind of spring ball type Finial device.
Background technology
Finial device uses when the machining usually as a kind of machining tool, and workpiece is interacted with instrument under the condition that pivots, and the site error of workpiece rotating axis has material impact to processing result and even lathe and instrument.There is following shortcoming in the Finial device that adopts at present: 1, traditional Finial device can not make the disposable processing of workpiece to the end, needs the parking clamping workpiece; 2, the top structural formula that adopts of present most of Finial device directly utilizes carbide alloy to make or connects tapered sleeve at the centre head outer surface by ratio-frequency welding top, when workpiece adds man-hour, because rotating speed is higher, excessive at the workpiece volume, in the situation of preponderance, cause easily the fracture of centre head; 3, on the top body of Finial device protective sleeve is not set, when workpiece adds man-hour, because rotating speed is higher, causes easily the wearing and tearing of top body.
Summary of the invention
The purpose of this utility model be provide in order to address the above problem a kind of use simple, working (machining) efficiency is high, the spring ball type Finial device of long service life.
The utility model is achieved through the following technical solutions:
A kind of spring ball type Finial device, comprise top body, centre head, pusher dog, spring, spring base and steel ball, described centre head and described pusher dog are arranged at the same end of described top body, described centre head and described pusher dog and described top body are slidingly connected, described top body is provided with cavity near an end of centre head, described steel ball is arranged in the described cavity, and the bottom of described cavity is provided with spring base, and described spring is fixed on the below of described spring base.
When with top body top tight workpiece, move after centre head is compressed, extrusion spring seat and steel ball move forward thereby promote pusher dog simultaneously, the end cutting edge of pusher dog thrusts workpiece end face and stirs workpiece rotating, when unclamping top body, under the effect of spring or spring base, centre head and workpiece are ejected, make workpiece can time processing complete, simultaneously do not need the clamping workpiece that stops, easy and simple to handle, efficient is high.
Further, the outer surface of described top body is provided with protective sleeve, and described protective sleeve is connected with described top body by screw.Outer surface at top body arranges protective sleeve, can effectively weaken because rotating speed causes the wearing and tearing of top body when higher.
Particularly, described protective sleeve is the polyurethane rubber protective sleeve.The polyurethane rubber protective sleeve has the following advantages: (1) anti-wear performance is remarkable: anti-wear performance is the highest in all rubber.(2) bumper and absorbing shock is good.Under the room temperature, the UR damper element can absorb the 10%-20% vibrational energy, vibration frequency is higher, energy absorption is larger.(3) coefficient of friction is higher, generally more than 0.5.
Further, the outer surface of described centre head is provided with taper sheath, and described taper sheath is fixedly connected with described centre head by screw thread.By at centre head taper sheath being set, can avoid because rotating speed situation higher or excessive at the workpiece volume, preponderance causes the fracture of centre head.
Particularly, described taper sheath is the carbide alloy taper sheath.
The beneficial effects of the utility model are:
By adopting technique scheme, make workpiece can time processing complete, do not need the clamping workpiece that stops simultaneously, easy and simple to handle, efficient is high.In addition, at the outer surface of top body protective sleeve is set, can effectively weakens because rotating speed causes the wearing and tearing of top body when higher.By at centre head taper sheath being set, can avoid because rotating speed situation higher or excessive at the workpiece volume, preponderance causes the fracture of centre head.
Description of drawings
Fig. 1 is the cutaway view of a kind of spring ball type Finial device of the utility model.
Among the figure: the top body of 1-, 2-spring support, 3-protective sleeve, 4-centre head, 5-pusher dog, 6-steel ball, 7-spring, 8-taper sheath.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments:
As shown in Figure 1, a kind of spring ball type of the utility model is top, comprise top body 1, centre head 4, pusher dog 5, spring 7, spring base 2 and steel ball 6, centre head 4 and pusher dog 5 are arranged at the same end of top body 1, centre head 4 is slidingly connected with pusher dog 5 and top body 1, and top body 1 is provided with cavity near an end of centre head 4, and steel ball 6 is arranged in the cavity, the bottom of cavity is provided with spring base 2, and spring 7 is fixed on the below of spring base 2.
When with top body 1 top tight workpiece, move after centre head 4 is compressed, extrusion spring seat 2 and steel ball 6 move forward thereby promote pusher dog 5 simultaneously, the end cutting edge of pusher dog 5 thrusts workpiece end face and stirs workpiece rotating, when unclamping top body 1, under the effect of spring 7 or spring base 2, centre head 4 and workpiece are ejected, make workpiece can time processing complete, simultaneously do not need the clamping workpiece that stops, easy and simple to handle, efficient is high.
The outer surface of top body 1 is provided with protective sleeve 3, and protective sleeve 3 is connected with top body 1 by screw.Protective sleeve 3 is the polyurethane rubber protective sleeve.Outer surface at top body 1 arranges protective sleeve 3, can effectively weaken because rotating speed causes the wearing and tearing of top body 1 when higher.The outer surface of centre head 4 is provided with taper sheath 8, and taper sheath 8 is fixedly connected with described centre head 4 by screw thread.Taper sheath 8 is the carbide alloy taper sheath.By at centre head 4 taper sheath 8 being set, can avoid because the fracture that rotating speed is higher or excessive at the workpiece volume, situation preponderance causes centre head 4.
