Abstract
The utility model relates to a chain sliding sleeve type balancing-weight mechanism with a rapidly moving, stably and safely operating main spindle box, comprising an upright column, a hold fast and a main spindle box which are arranged on the upright column, the upright column is provided with a balancing-weight hammer, the hold fast is provided with a guide wheel wrapped by a connecting piece, two ends of the connecting piece are respectively connected with the main spindle box and the balancing-weight hammer, which is characterized in that, the upright column is provided with the guide wheel, the balancing-weight hammer is provided with a guide bar socket, when the balancing-weight hammer rapidly operates, the utility model moves up and down without swinging, always moving up and down in direction of the guide bar, thereby having the advantages of high accuracy, relative safety and stability.
Description
Technical field
The utility model relates to a kind of balance weight mechanism of lathe, especially relates to a kind of main spindle box and moves fast the Link Chain Sliding Bush Type Balance Weight Organization of stable and safe in operation.
Background technology
Counterweight for lathe headstock, general employing steel wire rope and weight are by the connection of guide wheel, inertia owing to counter weight when the main spindle box oscilaltion is bigger, in main spindle box fast moving and the moment that stops, counter weight causes end play to increase owing to its own inertial is impacted the feed screw nut, can not guarantee the precision of lathe Z to coordinate.Steel wire rope is owing to friction fracture easily on guide wheel for a long time, and wire cable rupture causes main spindle box slide car, and weight comes off and smashes the lathe miscellaneous part.The manufacturer that has adopts the weight of hydraulic cylinder balancing main shaft case, has not only increased the cost of lathe, and hydraulic cylinder is difficult to reach same moved further with main spindle box when the lathe headstock rapid traverse simultaneously, has limited the fast moving of lathe.
The utility model content
The utility model mainly is that solution existing in prior technology lathe Z is lower to machining accuracy, the technical problem that cost is more high, a kind of guide rod that is provided with on column is provided, counter weight and guide rod cooperatively interact, and make lathe Z higher, and the lower Link Chain Sliding Bush Type Balance Weight Organization of production cost to machining accuracy.
The utility model also solves the rub technical problem of easily fracture etc. of existing in prior technology steel wire rope simultaneously on guide wheel, provide a kind of chain that adopts to replace the not Link Chain Sliding Bush Type Balance Weight Organization of easy fracture of steel wire rope.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of Link Chain Sliding Bush Type Balance Weight Organization, comprise column and support and the main spindle box which is provided with, be provided with counter weight in the column, support is provided with guide wheel, be wound with connector on the guide wheel, the two ends of connector link to each other with counter weight with main spindle box respectively, it is characterized in that: also be provided with guide rod on the described column, counter weight is provided with the guide rod seat, and described guide rod passes the guide rod seat and both cooperatively interact.By guide rod is set on column, guide rod passes counter weight and is provided with the guide rod seat, when counter weight moves fast, moves up and down and does not swing, and move up and down along the guide rod direction all the time, thereby precision is higher, and is safer and stable.
As preferably, be provided with sliding sleeve in the described guide rod seat, the internal diameter of sliding sleeve is suitable mutually with the external diameter of guide rod.Be provided with sliding sleeve in the guide rod seat, the internal diameter of sliding sleeve is suitable mutually with the external diameter of guide rod, has guaranteed that counter weight moves up and down along the guide rod direction all the time.
As preferably, described connector is a chain.Chain is comparatively firm as connector, not easy fracture.
Therefore, the utlity model has following characteristics: 1. simple in structure, reasonable in design; 2. column is provided with guide rod, and guide rod passes counter weight and is provided with the guide rod seat, and counter weight moves up and down along the guide rod direction all the time, and precision is higher, and is also safer and stable; 3. to replace original steel wire rope comparatively firm as connector for chain, not easy fracture.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is A portion enlarged drawings of accompanying drawing 1.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: a kind of Link Chain Sliding Bush Type Balance Weight Organization, and the support 2 and main spindle box 4 that comprise column 1 and which is provided with are provided with counter weight 5 in the column 1, and support 2 is provided with guide wheel 3, is wound with chain 9 on the guide wheel 3.The two ends of chain 9 link to each other with counter weight 5 with main spindle box 4 respectively, also be provided with guide rod 6 on the column 1, counter weight 5 is provided with guide rod seat 7, is provided with sliding sleeve 8 (referring to accompanying drawing 1) in the guide rod seat 7, the internal diameter of sliding sleeve 8 is suitable mutually with the external diameter of guide rod 6, by guide rod is set on column, guide rod 6 passes counter weight 5 and is provided with guide rod seat 7, when counter weight 5 moves fast, move up and down and do not swing, all the time move up and down along guide rod 6 directions, thereby precision is higher, safer and stable.Guide rod 6 passes sliding sleeve 8 and both cooperatively interact, and the sliding sleeve 8 that is provided with in the guide rod seat 7 has guaranteed that counter weight 5 moves up and down along the direction of guide rod 6 all the time.
