Abstract
The utility model discloses a guide rail unloading mechanism for a transverse slide carriage, belonging to the machine equipment field, which comprises a slide carriage. The utility model is characterized in that the upper plane of the transverse slide carriage is provided with an inclined hole of 75 degrees which is connected with a fixing nut via screws, the beam is processed with a slope guide rail inclined of 15 degrees and is embedded with a steel band, the inclined hole of the slide carriage is provided with a bearing support for guiding function, the lower end is provided with a heart regulation roller bearing via a pin for rolling on the steel band of the beam and a Belleville spring washer is provided between the upper end and the fixing nut. The utility model reduces the pressure on the reference guide rail of the beam, reduces the abrasion on the inlaid strip between the beam and the transverse slide carriage, uniformly distributes the force on the beam, reduces the deformation of the beam, changes the motion type from sliding to rolling and reduces the dragging force of the transverse slide carriage, thereby improving the accuracy of a machine.
Description
Technical field
The utility model belongs to machine tool field, specifically a kind of lathe guide rails unloading gear for transverse slide carriage.
Background technology
As everyone knows, along with the development of Machining Technology and the needs of mechanical processing industry, the large-sized gantry machine that can carry out large-scale workpiece processing arises at the historic moment, in order to adapt to the process requirements of high-power high pulling torque, crossbeam staged rectangular guideway becomes the design of large-sized gantry machine main flow, is widely used.In order to guarantee machining accuracy, the frame rigidity of machine-tool is strengthened greatly, and the deadweight of transverse slide carriage and ram milling head enlarges markedly, and has produced a series of problems thus:
One, the deadweight of transverse slide carriage and ram milling head all has been loaded on the crossbeam basic rack, has increased the load of crossbeam basic rack supporting surface greatly, easily causes the guide rail distortion.
Two, along with the operation of lathe, be subjected under the situation of enormous pressure at crossbeam basic rack supporting surface, the panel wearing and tearing between crossbeam and the transverse slide carriage aggravate, and have a strong impact on the precision of lathe.
Three, the pressure between crossbeam basic rack supporting surface and transverse slide carriage increases, and frictional force increases thereupon, and transverse slide carriage drive motors required torque increases, and has caused the extra duty of lathe, influences the operation of lathe.
Summary of the invention
In order to overcome the above-mentioned drawback of existing lathe, the utility model provide a kind of can be with the guide rails unloading gear for transverse slide carriage of deadweight 80% above off-load on the appointment steel guide rail of transverse slide carriage and ram milling head.
The utility model adopts following technical solution: be provided with slide carriage, it is characterized in that, 75 ° of inclined holes are opened on the plane on the transverse slide carriage, by the hold-down nut that is threaded, and 15 ° of slant rails of crossbeam processing, the insert steel band, the support of bearing is installed in the slide carriage inclined hole, is play the guiding role, the lower end is equipped with self-aligning roller bearing by bearing pin, on the crossbeam steel band, roll, between upper end and the hold-down nut disc spring film is installed.
The beneficial effects of the utility model: the pressure that greatly reduces the crossbeam basic rack; Reduce the panel wearing and tearing between crossbeam and the transverse slide carriage; Make the stressed even distribution of crossbeam, reduce beam deformation; It is to roll that forms of motion becomes slip, reduces the transverse slide carriage drawing force, finally improves machine tool accuracy.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1. nut 2.T shape is overlapped 6. 7. covers of 4. 5. supports of bearing of 3. axis of guides, 8. self-aligning roller bearings, 9. steel bands, 10. disk spring sheets, 11. keys.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, to help to understand content of the present utility model.
In Fig. 1, T shape cover 2 is fixed on the transverse slide carriage, impetus as sleeve mechanism, nut 1 is by being threaded on the T shape cover 2, the support of bearing 5 and transverse slide carriage inclined hole matched in clearance, play the guiding role, self-aligning roller bearing 8 is fixed on the support of bearing 5 by axle 6, to overlap 7 location self-aligning roller bearings 8, the axis of guide 3 is fixed on the support of bearing 5 by axle 4, general service disk spring sheet 10 is installed between the nut 1 and the support of bearing 5, and identical two cover mechanisms prevent deflection by key 11 location, regulate the decrement of general service disk spring sheet 10 by rotation nut 1, change the size of pressure, pressure finally is delivered on the steel band 9, realizes off-load.
75 ° of inclined holes are opened on the plane on the transverse slide carriage, by the hold-down nut 1 that is threaded; 15 ° of slant rails of crossbeam processing, insert quenching 65Mn steel band 9; The support of bearing 5 is installed in the slide carriage inclined hole, is play the guiding role, the lower end is equipped with self-aligning roller bearing 8 by bearing pin, rolls on crossbeam steel band 9; General service disc spring film 10 is installed, adjustable pressure between upper end and the hold-down nut 1; Whole slide carriage is equipped with four groups of mechanisms altogether, connects by key 11, guarantees that the directionality and the self-aligning roller bearing 8 of mechanism contacts with the line of crossbeam steel band 9.
Sleeve mechanism is installed on the transverse slide carriage, and by the key location, the centre is equipped with the disk spring sheet, and adjustable in pressure saves, and contacts with the crossbeam steel band to be bearing element.Sleeve mechanism is installed by the transverse slide carriage inclined hole, with long key with the same apparatus stationary positioned of connecting, general service disk spring sheet is installed between the nut and the support of bearing, can be changed pressure by adjusting nut, mechanism is finally with bearing element line way of contact contacting crossbeam steel band.
