Abstract
The utility model discloses an automatic clamping device for machining a super-long pipe fitting. The automatic clamping device consists of an annular body, support piles, a swinging rod and a pin, wherein the annular body is an annular component, an eccentric inner hole is formed in the annular component, a connecting line of two circle centers of the annular body is taken as a longitudinal datum line, the thinnest side of the annular body is located at an upper position, the thickest side of the annular body is located at a lower position, a support pile which is radially rotated and connected is respectively obliquely arranged at each of two sides of the thinnest side, the larger ends of the support piles face towards the circle center of the outer wall of the annular body, and an axial pin hole and an interlayer radial groove for communicating the inner wall with the outer wall are centrally formed in the thickest side of the annular body. The swinging rod is a rod component provided with an eccentric cam structure, the eccentric cam end of the swinging rod is inserted into the interlayer radial groove, and the eccentric cam end of the swinging rod and the interlayer radial groove are positioned and connected by the pin to form a lever type clamping structure which is externally provided with a moment arm. The automatic clamping device for machining of the super-long pipe fitting machine is simple in structure, reliable in clamping and easy in mounting and dismounting, and is very suitable for clamping and batch machining of the super-long pipe fitting.
Description
Technical field
The utility model relates to a kind of axle spare machined clamping device, and specifically, the utility model relates to a kind of for overlength pipe fitting machined automatic clamping device.
Background technology
Oil drill rocker, drill collar, sleeve pipe are the overlength pipe fitting, need to shape through machine cut.This type of workpiece material is steel alloy, and from great, length length, difficult cutting, machine cut adds man-hour, and pipe end will have enough large chucking power could satisfy the cutting requirement.Using maximum pipe end clamping devices in the prior art is heart carrier, although this clamping device is simple in structure, reliable clamping must be regulated clamping screw and could be realized clamping or unclamping pipe end during loading and unloading.Because the caliber of oil drill rocker, drill collar, sleeve pipe is thicker, the clamping screw that heart carrier is equipped with is corresponding also thicker, and the production line operation workman frequently regulates the large scale clamping screw need consume corresponding muscle power and man-hour, and so operating mode must reduce production efficiency.
The utility model content
The utility model is mainly for the deficiencies in the prior art, propose that a kind of syndeton is simple, loading and unloading are quick, the overlength pipe fitting machined automatic clamping device of reliable clamping, this device utilizes the lever eccentric wheel construction to realize that clamping force increases by on a year-on-year basis with cutting force, guarantees reliable grip.Automatically unclamp because losing the cutting force effect when unloading, can easily take off for subsequent use.
The utility model is achieved through the following technical solutions technical goal.
Overlength pipe fitting machined automatic clamping device, it is comprised of ring body, supporting pile, fork and pin.Its improvements are: described ring body is the circular member that is equipped with eccentric inner hole, take two circle center line connectings of ring body as vertical datum line, the featheredge of ring body is in upper, webbing is in the next, the tilting supporting pile that connects of spiral radially respectively in featheredge both sides, the large end of supporting pile is towards the center of circle of ring body outer wall, and the webbing of ring body is provided with between two parties axial pin-and-hole and links up the interlayer radial slot of inside and outside wall.Described fork is the rod member that is provided with the eccentric cam structure, and the eccentric cam end of fork is inserted in the interlayer radial slot, and both connect and compose the lever type clamping structure of the external arm of force by finger setting.
In the said structure, tilting supporting pile is positioned at the vertical datum line of ring body both sides 45
0～60
0On the RADIAL.
The utility model compared with prior art has following good effect:
1, the equipped radially supporting pile of adjustable position on the ring body, any clamping in the certain size scope is installed easily;
2, the fork that is provided with the eccentric cam structure cooperates with ring body and consists of the lever type clamping structure, and clamping force increases with cutting force, reliable clamping;
3, fork is the eccentric cam structure, and losing external force constraint can easily withdraw from, and loads and unloads laborsaving, quick.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Overlength pipe fitting machined automatic clamping device shown in Figure 1, it is by ring body 1, supporting pile 2, fork 3 and sell 4 and form.Described ring body 1 is for being equipped with the circular member of eccentric inner hole, take 1 two circle center line connectings of ring body as vertical datum line, ring body 1 featheredge is in upper, webbing is in the next, the tilting supporting pile 2 that connects of spiral radially respectively in featheredge both sides, supporting pile 2 is positioned at ring body 1 vertical datum line both sides 60 in the present embodiment
0On the line, supporting pile 2 is held towards the center of circle of ring body 1 outer wall greatly, and the webbing of ring body 1 is provided with between two parties axial pin-and-hole and links up the interlayer radial slot of inside and outside wall.Described fork 3 is for being provided with the rod member of eccentric cam structure, and the eccentric cam end of fork 3 is inserted in the interlayer radial slot, and both are located by connecting by pin 4 and consist of the lever type clamping structure of the external arm of force.
During the utility model practical application, regulate supporting pile 2 radial positions according to pipe fitting external diameter to be processed first, then cover installs on the pipe fitting end to be processed, withstand pipe fitting to be processed two ends at lathe, when pipe fitting rotation to be processed, the guide pile that fork 3 outer ends brush up against the machine tool chief axis end just forms clamping force, and the cutting force that cutting produces further increases clamping force, guarantees reliable clamping.Machined is removed an end bearing after finishing, and it is for subsequent use just can to take off the utility model from pipe end.
