Description

Technical Field

[0001] This utility model relates to the field of milling and turning machine tool technology, and in particular to a tailstock hydraulic locking structure. Background Technology

[0002] For lathes, the ejector assembly is located on top of the tailstock. The jaws connected to the spindle hold one end of the workpiece, while the other end of the workpiece is pushed and clamped by the ejector assembly. The lathe spindle must be coaxial with the ejector assembly. Typically, the tailstock is fixed to the guide rails of the machine tool base, with the ejector assembly horizontally mounted on top. However, the tailstock is very heavy, making it difficult to install it on the guide rails and ensure that the ejector assembly is coaxial with the spindle; in other words, the installation and calibration of the tailstock are quite inconvenient.

[0003] Therefore, this application provides a tailstock hydraulic locking structure, which divides the traditional tailstock into two parts: a tailstock mounting base and a tailstock. The weight of each part is nearly halved, and the step-by-step installation reduces the difficulty of installation. At the same time, a fine-tuning component is provided to enable fine-tuning of the tailstock's left-right and front-back positions, so as to facilitate the coaxial setting of the ejector pin assembly (tailstock) and the main shaft. Utility Model Content

[0004] The purpose of this utility model is to provide a tailstock hydraulic locking structure with a simple and reasonable structural design and stable and reliable operation. It divides the traditional tailstock into two parts: a tailstock mounting base and a tailstock. The weight of each part is nearly halved, and the step-by-step installation reduces the difficulty of installation. At the same time, a fine-tuning component is set to realize the fine adjustment of the tailstock's left and right and front and back positions, so as to facilitate the coaxial setting of the ejector pin assembly (tailstock) and the main shaft.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A tailstock hydraulic locking structure includes a machine tool base, a tailstock mounting base, a tailstock, and a push plate;

[0007] The machine tool base is horizontally positioned and has horizontally positioned guide rails on it;

[0008] The tailstock mounting base is located on the upper surface of the guide rail, and its bottom is provided with a gripper that grips the inner side of the guide rail.

[0009] Preferably, the tailstock mounting base is provided with a hydraulic component, and the gripper is a hydraulic gripper.

[0010] The upper surface of the tailstock mounting base is provided with a push plate lower slot, and the left side of the push plate lower slot is provided with a right fine-tuning groove for adjusting the position of the push plate to the right.

[0011] The push plate is vertically arranged, with flat surfaces on its left and right sides and two push blocks on its top.

[0012] The push plate is located in the slot below the push plate; the right fine-tuning groove is provided with a plurality of right fine-tuning wedges; the left side of the right fine-tuning groove is a right-inclined slope one; the left outer wall of the right fine-tuning wedge is a left-inclined slope two; slope one and slope two are in contact.

[0013] The right fine-tuning wedge has a threaded through hole; the tailstock mounting base corresponding to the fine-tuning wedge has a threaded hole, and a screw passes through the threaded through hole of the right fine-tuning wedge and connects to the threaded hole. As the screw is turned down, the right fine-tuning wedge is pushed to the right by the inclined surface to make a fine adjustment, that is, to push the push plate to the right and adjust the position of the push plate.

[0014] The tailstock has a slot on the push plate at its bottom, and a left fine-adjustment groove on the right side of the slot for adjusting the push plate position to the left. The tailstock is mounted on the tailstock mounting base, and the upper and lower ends of the push plate are inserted into the upper and lower slots of the push plate, respectively, thus completing the connection between the tailstock, the tailstock mounting base, and the machine tool base. This is mainly used to pre-fix the position between the tailstock and the tailstock mounting base. After calibrating the position, mounting holes are drilled on the upper surface of the tailstock mounting base to align the mounting holes on the tailstock with those on the tailstock mounting base.

[0015] The right side of the left fine-tuning sloping groove is slope three, and its rear side has threaded hole three. A movable left fine-tuning wedge is located inside the left fine-tuning sloping groove. The left fine-tuning wedge has a threaded through hole three in its center, and a slope four on its right side. A screw passes through the threaded through hole three and the threaded hole three to connect the left fine-tuning wedge to the left fine-tuning sloping groove. When the screw is turned down or fed in, the left fine-tuning wedge moves inward and is pushed to the left by slope three, thus pushing the push plate and fine-tuning push plate to the left.

[0016] The push plate has a horizontally arranged front adjustment through hole on the front side of the slot and a horizontally arranged rear adjustment through hole on the rear side. Adjustment screws are installed in both the front and rear adjustment through holes. The adjustment screws are threaded into the front adjustment through hole, pass through the front adjustment hole, and are attached to the push block of the top push plate. The adjustment screws are also threaded into the rear adjustment through hole, pass through the rear adjustment hole, and are attached to the push block of the top push plate. By turning the adjustment screws on the front or rear side of the knob, the push block (push plate) can be moved backward or forward.

[0017] The top of the tailstock is provided with a horizontal mounting cavity for mounting the ejector pin and hydraulic power components.

[0018] The beneficial effects of this utility model are:

[0019] It divides the traditional tailstock into two parts: a tailstock mounting base and a tailstock. The weight of each part is nearly halved, and the step-by-step installation reduces the difficulty of installation. At the same time, it is equipped with a fine-tuning component, which can make fine adjustments to the left-right and front-back positions of the tailstock, so as to facilitate the coaxial setting of the ejector pin assembly (tailstock) and the main shaft.
