Description

Technical Field

[0001] The utility model relates to the technical field of a lathe center frame, in particular to a lathe center frame. Background Art

[0002] The center frame is one of the main auxiliary tools of the lathe. When the lathe processes long shaft parts, in order to reduce the vibration and bending deformation of the workpiece during lathe processing, the center frame is often used to support and stabilize the workpiece; Patent No. CN202223312949.4 discloses a lathe center frame, with positioning grooves and bearings on the support arm. During the process of processing the workpiece, the bearings are used to enable the movable frame to cooperate with various types of parts, while the positioning grooves and bearings reduce the vibration of the movable frame; However, since there is no good measurement structure between the support arm, the movable frame and the base, the multiple groups of movable frames will appear long and short when they are moved later, and will have a certain impact on the subsequent workpiece limit. To this end, we propose a lathe center frame. Utility Model Content

[0005] A slide seat for support is slidably installed on the inner side of the rail seat, and there are two groups of slide seats. The inner circumferential surface of the rail seat is provided with tooth grooves for anti-slip, and there are multiple groups of tooth grooves. A fastening screw threadedly connected to the rail groove is threadedly installed on the outer wall surface of the slide seat, and a bearing body for support is rotatably installed on the outer side end surface of the rail seat.

[0006] By adopting the above technical solution, when the center frame of the lathe is used, the rail seat on the surface of the base and the clamping arm can be moved, so that the rail seat can slide and displace inside the rail groove and conveniently drive the bearing body to approach the workpiece in the center. At the same time, there are scale lines on the surface of the rail seat, the clamping arm and the base, so that the staff can more clearly understand the distance that the rail seat passes through the base and the clamping arm, so that the staff can more conveniently operate the center frame;

[0007] When the position of the rail seat in the rail groove is moved, the fastening screws on the surface of the slide seat slidably installed on the inner side of the rail seat can be rotated so that the fastening screws can be screwed with each other between the slide seat and can be screwed with the screw holes on the surface of the base or the clamp arm, and the slide seat can be pushed back conveniently so that the slide seat can be tightly abutted against the inner periphery of the rail seat, which is convenient for fixing the position of the rail seat, and the stability of the rail seat can be improved under the limitation of the two sets of fastening screws, so that the rail seat can support the bearing body more stably, and the bearing body can limit the workpiece being processed.

[0008] Specifically, a bracket for auxiliary support is welded on the bottom surface of the base, and a plate seat for limiting is fitted on the bottom surface of the bracket. The opposite sides of the bracket and the plate seat are equipped with threaded rods for connection, and a nut body for tightening is screwed on the outer periphery of the threaded rod.

[0009] By adopting the above technical solution, the bracket can conveniently support the base, and the bracket and the plate seat cooperate with each other, and the threaded rod and the nut body between the two can cooperate with each other, which is convenient for fixing the position of the base, so that the structure on the surface of the base can be used more stably.

[0010] Specifically, a fastening bolt for fixing is assembled between the base and the clamping arm.

[0011] By adopting the above technical solution, the fastening bolts can fix the position of the base and the clamp arm after they are fitted together, and are convenient for disassembly and assembly, and for controlling the opening and closing between the base and the clamp arm.

[0012] Specifically, the top surface and the bottom surface of the slide seat are both bonded with anti-slip rubber pads.

[0013] By adopting the above technical solution, the rubber pad has a certain anti-slip property, which is convenient for improving the tightness between the sliding seat and the inner side of the rail seat and the fastening screw when they are fitted together.

[0014] Specifically, a washer ring for support is sleeved and installed between the fastening screw and the sliding seat.

[0015] By adopting the above technical solution, the gasket ring can be used for auxiliary support, so that the stability between the fastening screw and the sliding seat is improved.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application, through the design of the clamp arm, rail groove, rail seat, scale lines and bearing body, can move the rail seat on the surface of the base and the clamp arm when the lathe center frame is in use, so that the rail seat can slide and displace inside the rail groove and conveniently drive the bearing body close to the workpiece in the center. At the same time, there are scale lines on the surface of the rail seat, the clamp arm and the base, so that the staff can more clearly understand the distance that the rail seat passes through the base and the clamp arm, so that the staff can operate the center frame more conveniently.

[0018] 2. The technical solution of the present application is designed with tooth grooves, sliding seats and fastening screws. When the position of the rail seat in the rail groove is moved, the fastening screws on the sliding seat surface slidably installed on the inner side of the rail seat can be rotated, so that the fastening screws can be screwed with each other between the sliding seat and can be screwed with each other with the screw holes on the surface of the base or the clamping arm, and the sliding seat can be pushed back conveniently, so that the sliding seat can be tightly abutted and fitted with the inner periphery of the rail seat, which is convenient for fixing the position of the rail seat, and under the limitation of the two sets of fastening screws, it is convenient to improve the stability of the rail seat, so that the rail seat can support the bearing body more stably, so that the bearing body can limit the workpiece being processed.
