TECHNICAL FIELD

[0001] The utility model relates to lathe processing technical field especially, relates to a main shaft box W axle oil pressure brake positioning mechanism. BACKGROUND

[0002] With the rapid development of manufacturing industry, the machining efficiency requirement of numerical control horizontal machining center is higher and higher, requires process concentration, and a large number of processes can be completed once clamped, and the spindle meets the high-speed finishing performance requirement and also meets the low-speed heavy cutting requirement.

[0003] Among them, the W-axis of the spindle plays an important role in the gantry machine tool, and the main functions include machining depth control, multi-axis linkage and improving machining efficiency. W-axis usually refers to the axis perpendicular to X-axis and Y-axis and moves along the direction of Z-axis, which is responsible for adjusting the position of the tool or workpiece in the vertical direction to ensure that the predetermined depth is reached in the machining process.

[0004] But the existing main shaft box W axis composition structure is relatively simple, and a certain brake positioning structure is lacked on the W axis, thereby affecting the use effect of the W axis. INVENTION CONTENTS

[0005] The utility model discloses a main shaft box W axle oil pressure brake positioning mechanism is provided to solve the problem that a certain brake positioning structure is lacked on the W axis in the background art.

[0006] In order to achieve the above object, the utility model adopts the following technical scheme:

[0007] A main shaft box W axle oil pressure brake positioning mechanism, including W axle connecting seat and two guide rails that are symmetrically arranged, the top of W axle connecting seat and guide rail is slidably connected through support sliding block, the bottom of W axle connecting seat is fixedly connected with brake sliding block, the brake sliding block is slidably sleeved on the top of guide rail, a plurality of oil inlets are arranged on the side of brake sliding block.

[0008] Preferably, the bottom of the support sliding block and the W axle connecting seat are fixedly connected through a plurality of fastening bolts.

[0009] Preferably, the both ends of the brake sliding block are fixedly connected with sealing rings through fixing bolts.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. In the utility model, the brake positioning of the W axis can be effectively realized through the brake sliding block structure, so that the use effect of the W axis is effectively improved.

[0012] 2. The fastening bolts in this utility model can facilitate the fixing of the support slider, while the sealing ring can ensure the sealing of the brake slider. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figs. 1-3 A hydraulic brake positioning mechanism for the W-axis of a spindle box includes a W-axis connecting seat 1 and two symmetrically arranged guide rails 2. The top of the W-axis connecting seat 1 and the guide rails 2 are slidably connected by a support slider 3.

[0019] In this embodiment, the support slider 3 is fixedly connected to the bottom of the W-axis connecting seat 1 by multiple fastening bolts 6, which facilitates the connection and fixation of the support slider 3 and the W-axis connecting seat 1. The bottom of the W-axis connecting seat 1 is fixedly connected to a brake slider 4, which is slidably sleeved on the top of the guide rail 2 for positioning and fixing the W-axis connecting seat 1.

[0020] In this embodiment, the brake slider 4 is provided with multiple oil inlets 5 on one side, and both ends of the brake slider 4 are fixedly connected with sealing rings 8 by fixing bolts 7 to ensure the sealing of the brake slider 4.

[0021] In this embodiment, when oil is introduced into the brake slider 4 through the oil inlet 5, the brake slider 4 will lock with the guide rail 2, and the W-axis connecting seat 1 connected to the brake slider 4 will also lock and remain stationary.

[0022] In this embodiment, the brake slider structure can effectively brake and position the W-axis, thereby improving the performance of the W-axis.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
