Abstract
The utility model relates to a lathe center device, which comprises a lathe center body (5) gripped in an expanding core (2). A bolt (1) is connected the expanding core (3) with a expanding sleeve (4). A spring is arranged between the lathe center body and the expanding core and the expanding core is embedded between a guard plate (2) and the expanding sleeve (4). A baffle (6) used to fix the lathe center body is connected with the expanding core (3) with a screw (7). The utility model can ensure the fastening rigidity and the concentricity of the lathe center body and the lathe main shaft, which can improve the precision and efficiency for machining long axis effectively.
Description
Technical field
The utility model belongs to the mechanical device field, particularly relates to a kind of lathe Finial device.
Background technology
In textile machinery industry, roller is important parts.Along with the client is more and more higher to the required precision of textile machine, also more and more higher to the processing request of roller.Because roller is a kind of slender axles part, the guide hole of processing is at the front end of part, and in the process, the endoporus of requirement assurance part and cylindrical circular runout are less than 0.012mm, and the guide hole circularity that requires part simultaneously is less than 0.005mm.The center bearing bracket that processing technology in the past adopts is in the outside picking-up mode of main shaft, but processing mode can't improve owing to cutting linear velocity like this, cause working (machining) efficiency too low, work in-process is easy to damage the outer surface of roller part in addition, thereby cause part scrap (annotate: part before Vehicle Processing outside the garden be grinding, surface roughness is Ra0.8).Because processing line speed is low, the roughness of guide hole inwall and garden degree also can't reach higher requirement simultaneously, need to increase grinding process and could guarantee that part arrives the product quality requirement.
Summary of the invention
The purpose of this utility model be at traditional lathe top when the processing slim axle machining accuracy and inefficient situation, a kind of Finial device with precision of raising the efficiency of processing slim axle usefulness is provided.
The technical solution of the utility model is such.The embedded top fixed sharp body that comprises of this lathe, top body is clamped in the core that rises, and bolt is connected with the core that rises by ringfeder, top body and rise and be mounted with spring between the core, the core that rises is inlaid between backplate and the ringfeder, and the baffle plate of stationary center body is connected with the core that rises by screw.The principle of this device is: top behind spindle hole good position decided at the higher level but not officially announced, pull back by the bolt core that will rise, the conical structure that the core that rises matches with backplate is with the backplate spreading, and the backplate support behind the spreading realizes top location by stiction on the inwall of lathe hollow type main shaft.Top in spindle hole the location after, in the end retraction spindle hole that roller can not be processed, by embedded top holding out against.Like this, because clamping point and processing stand distance shorten greatly, processing conditions becomes and is equal to minor axis class part, has increased substantially the processing rigidity of part.Part in the part retraction spindle hole can not swung in the process of High-speed machining because embedded top holding out against arranged, and can carry out High-speed machining fully, has effectively guaranteed the efficient and the precision of roller processing.
The utlity model has following remarkable result: 1, can adjust rapidly and change the position of fixed sharp body in the main shaft endoporus; 2, can be fixing in the main shaft endoporus reliably, guarantee the rigidity that holds out against; 3, the fixed concentricity that can well keep top body and main shaft; 4 can effectively improve the precision and the efficient of processing slim axle.
Brief Description Of Drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of the utility model Fig. 1 is to schematic diagram.
Each parts of the present utility model are: the 1-bolt 2-backplate 3-top body 6-of the core 4-ringfeder 5-baffle plate 7-screw 8-spring 9-clamping screw 10-fabrication hole that rises
As shown in the figure, top body (5) is clamped in the core that rises (2), and bolt (1) is connected with the core that rises (3) by ringfeder (4).Be mounted with spring (8) between top body (5) and the core that rises (3), the core that rises (3) is inlaid between backplate (2) and the ringfeder (4), and the baffle plate (6) of stationary center body (5) is connected with the core that rises (3) by screw (7).Clamping screw (9) is used at assembling process fixedly ringfeder (4) and the core that rises (3).Fabrication hole (10) is used for the attrition process of backplate (2).
The specific embodiment
Embodiment is in conjunction with Fig. 1, Fig. 2 explanation.
This device is to use in numerically controlled lathe, in order to processing textile machine tool part-roller.Bolt (1) adopts the M12 bolt.Pull back by bolt (1) core (3) that will rise, the core that rises (3) is when displacement backward, and with 4 backplates (2) spreading, the outer side stay of the backplate behind the spreading realizes the location of top body (5) by stiction on the inwall of numerically controlled lathe hollow type main shaft.Processing is during roller, can guarantee the rigidity that holds out against and with the concentricity of main shaft, improved machining accuracy.The backplate number of the utility model embodiment is 4.Actual backplate number can be between 3-6.
Claims (2)
1, lathe spindle is embedded top, comprise top body (5), it is characterized in that, top body (5) is clamped in the core that rises (2), bolt (1) is connected with the core that rises (3) by ringfeder (4), be mounted with spring (8) between top body (5) and the core that rises (3), the core that rises (3) is inlaid between backplate (2) and the ringfeder (4), and the baffle plate (6) of stationary center body (5) is connected with the core that rises (3) by screw (7).
2, lathe spindle according to claim 1 is embedded top, and the quantity that it is characterized in that backplate (2) is between 3-6.
