100 are put to clamp cutter and comprising pedestal 200, grip slipper 300 and spacing group 400.
Pedestal 200 includes body 210, reception hole 220 and non-circular guide groove 230, reception hole 220 be arranged at body 210 and
Comprising inwall 221 and perforate 222, perforate 222 is located on inwall 221；Non-circular guide groove 230 is located at body 210 and passes through perforate
222 connect with reception hole 220, and non-circular guide groove 230 has axial I1.Grip slipper 300 is arranged at pedestal 200 and comprising setting
Portion 310 and base shank 320, setting unit 310 are set for cutter group, and base shank 320 connects setting unit 310, and base shank 320 is inserting
Reception hole 220 and comprising handle body 322 and at least one location division 321, handle body 322 is located in reception hole 220, and location division 321 is recessed
Located at handle body 322 and position it is corresponding with perforate 222.Be arranged at non-circular guide groove 230 for spacing group 400 and comprising clamp holder 420 and
Bolt 410, clamp holder 420 are located in non-circular guide groove 230, the section of the cross sectional shape of clamp holder 420 and non-circular guide groove 230
Shape is corresponding, and bolt 410 passes through clamp holder 420；Wherein swivel bolt 410 can make clamp holder 420 I1 is moved to out vertically
Location division 321 is supported in hole 222, so that the packing handle body 322 of clamp holder 420.
Whereby, the rotation of the noncircular cross section limitation clamp holder 420 of non-circular guide groove 230, after making it be driven by bolt 410
Can I1 displacements vertically with packing base shank 320, therefore can reach simple in construction and group sets easy purpose；Pedestal simultaneously
200 structure simply enables the integrality of structure be maintained, and is with the increase of the intensity of pedestal 200, and when can also resist use
Reaction force.The CONSTRUCTED SPECIFICATION of cutter holding device 100 will be described in greater detail below.
Reception hole 220 and non-circular guide groove 230 are all the hole for being opened in body 210, reception hole 220 and non-circular guide groove
230 both are staggered and have connected component.That is, the perforate 222 on the inwall 221 of reception hole 220 is simultaneously and not rounded
Perforate on the inwall of shape guide groove 230, and reception hole 220 and non-circular guide groove 230 are interconnected.
Grip slipper 300 is by the way that base shank 320 is inserted in reception hole 220 to be mounted on pedestal 200, in order that folder
The group for holding seat 300 and pedestal 200 sets more firm, and the setting unit 310 of grip slipper 300 can be made to include the chimeric linker shank of section 311
320, reception hole 220 includes round mouth 223 and connects external environment, and pedestal 200 is also arranged at this comprising positioning recessed 240, positioning recessed 240
Body 210 and section 311 is correspondingly fitted together to comprising the shape of embeded slot 241, and embeded slot 241 includes bottom wall 2411, and wherein round mouth 223 is located at
Bottom wall 2411, after handle body 322 inserts reception hole 220 by round mouth 223, chimeric section 311 is embedded in embeded slot 241；In addition, setting unit
310 can be also comprising multiple composition surfaces 312 around connected embedding section 311, and position recessed 240 and also surround comprising multiple locating surfaces 242
Embeded slot 241 and corresponding with composition surface 312.
In more detail, embeded slot 241 is to be depressed in body 210 and general rectangular shallow slot structure, multiple locating surfaces 242
Indent is formed in the positioning of body 210 recessed 240 with embeded slot 241 around embeded slot 241, because round mouth 223 is located at embeded slot
241 bottom wall 2411, be with when the handle body 322 of grip slipper 300 via round mouth 223 enter reception hole 220 after, setting unit 310
Chimeric section 311, which can be installed with, is limited in embeded slot 241, while allows the composition surface 312 and Xiang Hu Arrived of locating surface 242 tops to coordinate.
In the present embodiment, each composition surface 312 and the shape of each locating surface 242 correspond to each other, and multiple composition surfaces 312 are rings
Shape is distributed in chimeric section 311, and multiple locating surfaces 242 and annular distribution are in embeded slot 241, so when each composition surface 312 and respectively
After locating surface 242 is corresponding, self-centering function can be provided to avoid handle body 322 eccentric with reception hole 220, there is provided enough branch
Support force is to increase the stability of cutter when in use.
Clamp holder 420 includes the screw thread couple of screw 425, screw 425 and bolt 410, and due to non-circular guide groove 230
Non-circular shape can cause clamp holder 420 to be restricted in the rotation of non-circular guide groove 230, therefore when bolt 410 rotates, packing
Block 420 can not follow rotation and be forced along axial I1 movements.So when the base shank 320 of grip slipper 300 inserts reception hole 220
Afterwards, location division 321 can correspond exactly to the position of perforate 222, and now rotating bolt 410 allows clamp holder 420 to be displaced to perforate
222 position, location division 321 can be caught in, and cause base shank 320 can not be pulled out reception hole 220.
The cross sectional shape of non-circular guide groove 230 can be in generally ellipse, and clamp holder 420 is in oval rod structure.When clamp holder 420
When being oval rod structure, smoothness when can increase it I1 being moved vertically, while can avoid any position stress concentration and
Increase service life, but in other embodiments, the section of non-circular guide groove 230 can also be any non-round shape, such as
It is triangle, square, rectangle or polygon, comprising above-mentioned but be not limited.
The clamp holder 420 of the present embodiment also includes first end face 421, second end face 422, rank portion 424 and inclined-plane 423, the
Biend 422 is relative with first end face 421, and rank portion 424 connects first end face 421, and inclined-plane 423 is connected to rank portion 424 and second
Between end face 422.And location division 321 is the depressed part on handle body 322, location division 321 can include support surface 3211, support surface
3211 from the opposite side of the oblique handle body 322 in the side of handle body 322, and support surface 3211 is supported by inclined-plane 423.That is, support
The gradient and incline direction of top surface 3211 coordinate gradient and the direction on the inclined-plane 423 of clamp holder 420, therefore clamp holder 420 is vertically
, can gradual packing location division 321 when I1 is moved up.
Referring to Fig. 6, wherein Fig. 6 illustrates a kind of cutter holding device 100a according to another embodiment of the utility model
Diagrammatic cross-section.Cutter holding device 100a is similar with the cutter holding device 100 described in Fig. 1 to Fig. 5, but reception hole 220a
Comprising a section 224a is inside contracted, grip slipper 300a base shank 320a also coordinates comprising cone section 323a inside contracts a section 224a.As shown in fig. 6,
Reception hole 220a is formed towards the gradual narrow contracting in end and is inside contracted a section 224a, and base shank 320a handle body 322a meat thickness is also gradual towards end
Inside contract and form cone section 323a, by inside contracting section 224a and boring section 323a setting, grip slipper 300a base shank can be allowed
320a is easier to insert in reception hole 220a, and the cooperation bored section 323a and inside contract section 224a can also have self-centering effect
Fruit.
Referring to Fig. 7, wherein Fig. 7 illustrates a kind of cutter holding device 100b according to the utility model a further embodiment
Application schematic diagram.Cutter holding device 100b is arranged at the milling and planing drum 500b of road milling machine, cutter holding device 100b's
Structure is identical with Fig. 1 to Fig. 5 cutter holding device 100, and wherein pedestal 200b reception hole 220b has hole axle to I2 (x-axis
Direction) vertical milling and planing drum rouses axially (vertical paper, z-axis direction), rather than circular guide 230b has axial I1 (y-axis direction)
Upright opening axial direction I2 and drum are axially.Whereby, when the cutter N clamped by cutter holding device 100b will be changed, can directly grasp
Make spacing group and release grip slipper 300b, will not be interfered by other cutter holding devices, increase operation convenience.
Although the utility model is disclosed as above with embodiment, so it is not limited to the utility model, any
