Specific embodiment
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
The structure diagram of the present invention is as shown in Figure 1.A kind of Five-axis NC Machining Center angle head fixing device, including positioning member
Four part, retaining element, clamping element and locking element parts.The setting element is 1 locating piece；The retaining element is
1 retainer ring；The clamping element is 2 positioning screws, and locking element is 6 lock-screws.The inside groove size root of retainer ring
According to machine tool chief axis size design, two working faces of locating piece are closely connect respectively with retainer ring and angle head, and retainer ring is fixed
On the main shaft of lathe, lock-screw tightens main shaft, and the degree that lock-screw is tightened is subject to retainer ring and does not lock, do not glide.
Locating piece is sleeved on the positioning column of angle head, and orientation trouble is aligned to angle head handle of a knife slot.
Particularly, copper backing can be added between retainer ring and main shaft.
The angle head fixing device is four setting element, retaining element, clamping element and locking element parts, is ordered respectively
Entitled locating piece（As shown in Figure 1）, retainer ring（As shown in Figure 2）, positioning screw, lock-screw（As shown in Figure 3）.Because each
The specification of numerically-controlled machine tool is different, and the size of each part is also not quite similar in component, and this example, which is only used as, meets the lathe function requirement
Preferred embodiment.The inside groove size of retainer ring is according to machine tool chief axis size design, and outer profile size is without too big requirement.
The working face for positioning block size is more demanding, and two working faces are closely connect respectively with retainer ring and angle head.In order to shorten processing
Period, screw can be with selection standard elements.
Angle head fixing device as shown in Figure 4.In the device, 10 parts of totally 4 class, including fixed block 1, retainer ring
1, lock-screw 6, positioning screw 2.It is fixed since positioning reference plane and locating piece working surface contact area are smaller
Position accuracy demand between position block and retainer ring is higher.
Fig. 5 is clamping schematic diagram of the fixing device on machine tool chief axis.In order to limit the freedom between retainer ring and main shaft
Degree, it should be tightened with lock-screw to main shaft.For the ease of locking, copper backing should be added between retainer ring and main shaft.
Retainer ring is fixed on the main shaft of lathe, is moved to the upper end of main shaft in advance.Main shaft and fixation are connected with screw
Ring respectively adds a scale copper on the contact surface of main shaft and screw, prevents screw from weighing main shaft wounded.The degree of screw-driving will fit
When retainer ring of being subject to does not lock, do not glide.
Locating piece is sleeved on the positioning column of angle head, orientation trouble is aligned to angle head handle of a knife slot.By angle head
Upwards close to main shaft, the retainer ring for being moved to eminence in advance with the mounting hole of fixed block is aligned, the screw of retainer ring is unclamped,
Retainer ring is moved down into a certain distance from main shaft eminence.Retainer ring is locked, keeps its mounting hole in the process with consolidating
Determine the mounting hole alignment of block.The tightening pin of angle head is tightened, eliminates the gap between angle head and locating piece.Installation is complete,
Cutter is connected on the clamping device of angle head to work.
Common machine tool fixture material includes various steel, the copper materials such as Q235 steel, 45 steel, T8 steel, Cr12 steel, HT20
Material.According to the rigidity of machine tool chief axis, chucking power size, in line with use condition is met under the premise of reduce the principle of cost to the greatest extent,
This example selects the material of carbon structural steels or steel alloy 42CrMo as angle head positioning device, and hardness is 36~42HRC.It should
Material purchase is convenient, heat treatment performance is preferable.
In this example, Five-axis NC Machining Center is than the poor rigidity of machine tool, and parts to be processed belongs to thin-wall part, in process
The torque of cutter is smaller, not high to the intensity requirement of fixing device.
Although being described in conjunction with the accompanying embodiments of the present invention, patent owner can be in appended claims
Within the scope of make various deformations or amendments, as long as no more than the present invention the described protection domain of claim, all should
Within protection scope of the present invention.
