Description
Technical field
The utility model relates to a kind of ball screw positioning device of achievable resetting, which is able to achieve ball wire
The resetting of bar and safe and reliable, is well positioned to meet the needs of user.
Background technique:
Currently, the positioning method of existing ball screw bearing block generallys use taper pin with internal thread positioning, because of corresponding zero
It is difficult to realize high-precision at the cooperation of part and taper pin with internal thread to process, practical repetitive positioning accuracy is difficult to meet requirement.
It is serious to will lead to taper pin with internal thread deformation after lathe collides, it is caused to be difficult to take out.
Summary of the invention:
The utility model provides a kind of ball screw positioning device of resetting, ensure that and meets wanting for resetting
It asks and convenient for disassembly and assembly, reduces user to the maintenance difficulty of lathe.
The specific technical solution of the utility model is as follows:
The ball screw positioning device of resetting, for being located by connecting the bearing block at ball screw both ends to lathe
Crossbeam on, including crossbeam mounting groove, ball screw and bearing block further include baroclinic block and bearing block cushion block, work as ball screw
When the bearing block at both ends is installed to the crossbeam mounting groove of two sides, first passes through bolt and bearing block is located by connecting to crossbeam, each
Bearing block two sides also pass through baroclinic block and bearing block cushion block is located by connecting.
The further design of the utility model is:
Baroclinic block and bearing block cushion block installation site are provided on the crossbeam mounting groove of two sides.
Two side shaft holders are equipped with the shaft shoulder, and by connecting at the shaft shoulder with crossbeam mounting groove, crossbeam mounting groove corresponding shaft bearing seat
The shaft shoulder on the outside of on be provided with installation site, baroclinic block and bearing block cushion block correspondence are mounted on the crossbeam mounting groove inner pedestal shaft shoulder
Outside.
Baroclinic block and bearing block cushion block are installed to mutual in 180 degree Angle Position along bearing block circumference.
Baroclinic block uses 30 degree of angles of baroclining.
The utility model has the advantages that compared with prior art
1. the ball screw positioning device of the utility model design is convenient for disassembly and assembly, it is difficult to the maintenance of lathe to reduce user
Degree, improves the maintainability of lathe.
2. the utility model reduces the difficulty of the secondary assembly in scene to make ball screw realize repeatable positioning with more preferable
The needs for meeting user.
Detailed description of the invention

Specific embodiment
The utility model is further described with reference to the accompanying drawing:
Embodiment one:
As shown in Figure 1 and Figure 2, the ball screw positioning device of the repeatable positioning of the numerically-controlled machine tool of the utility model design, can
Realize that the resetting of ball screw reduces being located by connecting to the crossbeam of lathe for the bearing block at ball screw both ends
The difficulty of the secondary assembly in scene.
The device mainly includes: baroclinic block 1, ball screw 3, bearing block 2, bearing block cushion block 4 etc.；When ball screw both ends
The installation of bearing block 2 in two sides crossbeam mounting groove 5 when, first pass through bolt 7 and bearing block be located by connecting to crossbeam, each axis
Hold that 2 two sides of seat also pass through baroclinic block 1 and bearing block cushion block 4 is located by connecting.Two bearing block cushion blocks 4 of the present apparatus and two baroclinic blocks
Cooperation between 1 can meet resetting of the ball screw bearing block in one direction.Baroclinic block 1 uses 30 degree of angles of baroclining, can
Sufficiently meet positioning requirements.Realize that the assembly precision of ball screw is wanted when assembling for the first time by adjusting the thickness of bearing block cushion block 4
It asks, when needing to adjust ball screw assembly precision again, it is only necessary to adjust the thickness of bearing block cushion block 4.
Two side shaft holders are equipped with the shaft shoulder, and by connecting at the shaft shoulder with crossbeam mounting groove 5, crossbeam mounting groove corresponding shaft bearing seat
The shaft shoulder on the outside of on be provided with installation site, baroclinic block 1 and the correspondence of bearing block cushion block 4 are mounted on crossbeam mounting groove inner pedestal axis
On the outside of shoulder.Baroclinic block and bearing block cushion block are installed to mutual in 180 degree Angle Position along bearing block circumference.
The particularity of the fixed form of the utility model ball screw bearing block, one side use a bearing block cushion block
4 realize precision positioning between ball screw bearing block 2 and crossbeam mounting surface respectively, and the other side then uses two 30 degree to barocline
Block 1 realizes radial locking.When ball screw needs to adjust again, it need to only remove and face upward a side shaft holder cushion block and it is carried out in right amount
It is ground to ball screw and is in horizontality.
The utility model resetting type positioning device with lead screws, 3 both ends of ball screw are respectively charged into bearing block 2, to axis
Seat 2 is held slightly to pre-tighten.Ball screw bearing block cushion block 4 and baroclinic block 1 are separately fixed on crossbeam.
Utility model works process:
All components of the present apparatus are installed according to the step of embodiment one.
1. will face upward head first when ball screw needs to adjust and sidewinder ballscrew bearing block, ball screw bearing block cushion block
It is unclamped with baroclinic block.
2. adjusting the thickness of ball screw bearing block cushion block until ball screw is in horizontality.
3. respectively by ball screw bearing block, ball screw bearing block cushion block and two baroclinic block lockings.
Embodiment two:
This example is different from one place of implementation and is, baroclinic block and bearing block cushion block are along bearing block circumference to being mutually in an angle of 90 degrees
Or 120 Angle Position installation, can also realize positioning, remaining is the same as embodiment one.
