Description
Technical field
The utility model belongs to mechanical package applied technical field, is specifically related to a kind of dust cover for machine tool lead screw bearing block, and when working for lathe, pair bearing block be connected with leading screw seals, and ensures the stability of bearing block support and connection work, ageing.
Background technology
Lathe (English name: machinetool) refers to the machine of manufacturing machine, also known as machine-tool or toolroom machine, is called for short lathe traditionally.Generally be divided into Metal Cutting Machine Tool, forging machine tool and wood craft machines etc.In modern mechanical manufacturing, the method for processing equipment part is a lot, except machining, also has casting, forging, welding, punching press, extruding etc., in every case the part that required precision is higher and surface roughness requirements is thinner is belonged to, generally all finally need process by the method for cutting on lathe, lathe plays significant role in the construction of national economic modernization, be widely used in machine-building and repair factory, as numerically controlled lathe, it is a kind of automated machine tool that program control system is housed, this control system can logically process has control coding or other symbolic instruction regulated procedures, and by its decoding, thus make machine tool action and the control unit of processing parts, operation and the monitoring of Digit Control Machine Tool all complete in this numerical control unit, it is the brain of Digit Control Machine Tool, there is machining accuracy high, and stable crudy, the interlock of multi-coordinate can be carried out, the part of energy machining shape complexity, when processing parts changes, generally only need to change numerical control program, the Operational preparation time can be saved, the precision of lathe itself is high, rigidity large, can select favourable machining dosage, productivity ratio high (being generally the 3-5 of machine tool doubly), Machinery Tool Automation degree is high, can reduce labor intensity.
Traditional Digit Control Machine Tool is usually by main frame, numerical control device, drive unit, the parts such as servicing unit composition, its composition and assembly structure more complicated, as main frame comprises bed piece, column, main shaft, the mechanical parts such as feed mechanism, it is the mechanical part for completing various machining, and drive unit comprises main shaft drives unit, feed unit, spindle motor and feeding motor etc., it realizes main shaft and Feed servo system by electric or electrohydraulic servo system under the control of numerical control device, when several feeding interlock, can complete location, straight line, the processing of plane curve and space curve, in order to ensure precision and the high efficiency of lathe production operation, the feed mechanism of main frame and the feed unit of drive unit during installation, spindle motor and feeding motor etc., need stable, be arranged on accurately bed piece lead screw shaft bearing on, namely directly the installation of traditional leading screw and bearing block, uses, the dust produced of operating table surface after long-term work after it assembles debugging, greasy dirt, cutting fluid, iron filings, aluminium bits etc. enter the two joint face, cause bearing block service wear, corrosion is comparatively large, and then affects positioning precision and the repetitive positioning accuracy of driving work, has a strong impact on leading screw life-span and bearing life simultaneously, transmission accuracy is caused not reach production requirement, cause production product percent of pass low, waste of raw materials is serious, and this is current urgently to be resolved hurrily.
Therefore, based on the problems referred to above, the utility model provides a kind of dust cover for machine tool lead screw bearing block.
Utility model content
Utility model object: the purpose of this utility model is to provide a kind of dust cover for machine tool lead screw bearing block, its reasonable in design and be convenient to assembling, effectively stopped entering of various foreign, extended the service life of leading screw and bearing block.
Technical scheme: the utility model provides a kind of dust cover for machine tool lead screw bearing block, comprise connection centring ring, and be evenly arranged on the nut locating hole connected on centring ring, and be arranged on the sealing and dustproof groove connected on centring ring, and be arranged on the connection stopper slot of sealing and dustproof groove one end.
The technical program, described with bearing block with the use of the quantity of nut locating hole at least arrange six.
The technical program, the described dust cover for machine tool lead screw bearing block, also comprises the passage being arranged on and connecting in the middle of stopper slot.
The technical program, described connection stopper slot is set to spill smooth structure.
The technical program, described sealing and dustproof groove is cylindrical structural.
Compared with prior art, the beneficial effect of a kind of dust cover for machine tool lead screw bearing block of the utility model is: 1, its reasonable in design and be convenient to assembling, effectively stop entering of various foreign, extend the service life of leading screw and bearing block, improve production quality and efficiency; 2, sealing and dustproof groove after this structure is installed, effectively stop entering of the foreign matters such as external dust, greasy dirt, cutting fluid, iron filings, aluminium bits, and foreign matter enters the forfeiture of the rear wearing and tearing that cause bearing block inside and lubricating grease, ensure that the clean and lubrication of leading screw and bearing block joint face, effectively extend service life, improve positioning precision and the repetitive positioning accuracy of lathe, produce the steady quality of product, efficiency is high.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of a kind of dust cover for machine tool lead screw bearing block of the present utility model;
Fig. 2 is the vertical TV structure schematic diagram of a kind of dust cover for machine tool lead screw bearing block of the present utility model;
Wherein, in figure, sequence number mark is as follows: 1-connection centring ring, 2-nut locating hole, 3-sealing and dustproof groove, 4-connect stopper slot, 5-passage.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
A kind of dust cover for machine tool lead screw bearing block as depicted in figs. 1 and 2, comprise and connect centring ring 1, and be evenly arranged on the nut locating hole 2 connected on centring ring 1, and be arranged on the sealing and dustproof groove 3 connected on centring ring 1, and be arranged on the connection stopper slot 4 of sealing and dustproof groove 3 one end.
