Example 1

The present embodiment specifically provides an extended stroke tool rest for a vertical lathe to explain the above technical contents, and aims to solve the practical problem of processing a columnar workpiece by a vertical lathe through the tool rest. This knife rest mainly includes: the machine tool seat, the tool rest seat and the lifting adjusting mechanism are respectively designed as follows as shown in figure 1:

seat of machine tool

Install the lathe seat on vertical lathe, when in-service use, one side of lathe seat is equipped with the location grip block, and the grip block of just fixing a position and the looks adaptation of vertical lathe, and concrete accessible a plurality of bolt locking is fixed to the realization is fixed to the installation of lathe seat, if: the machine tool base is provided with a plurality of threaded mounting holes, and the machine tool base is clamped and fixed at the corresponding position of the vertical machine tool through each threaded mounting hole.

Seat of tool rest

The tool rest is designed in a sliding assembly mode with the tool rest base and the machine tool base, the tool rest base is used for clamping a machining tool, a plurality of threaded mounting holes are arranged on the tool rest base in a similar mode, and the turning tool is clamped and fixed through the threaded mounting holes.

When the tool rest is actually applied, a sliding groove is formed in the machine tool seat along the vertical lifting direction of the vertical lathe, a sliding block is arranged in the sliding groove and connected with the tool rest seat, the sliding block and the tool rest seat can be integrally formed, when the sliding block on the tool rest seat slides along the sliding groove, the tool rest seat can do lifting motion relative to the machine tool seat, and then the height of the tool can be adjusted, so that the tool can meet the maximum axial machining size of different workpieces.

In order to achieve the sliding stability of the slider in the slide groove, the slide groove is formed in a dovetail groove shape as shown in fig. 3, whereby the sliding stability of the slider in the slide groove can be ensured. On the other hand, in order to ensure that the cutter can bear enough torque during turning machining while sliding, the sliding grooves are symmetrically arranged relative to the central shaft of the machine tool seat, and at the moment, when the sliding blocks on the tool rest seat slide in the corresponding sliding grooves, the sliding blocks can have enough stability and bear enough turning force, so that the machining precision of the cutter is reliably guaranteed.

Lifting adjusting mechanism

In order to realize that the working length of the cutter can be adaptively changed according to the maximum axial size of the workpiece to be machined and the axial stroke of the tool rest of the machine tool, as shown in fig. 2, a lifting adjusting mechanism is arranged on the machine tool seat, and the tool seat frame is driven by the lifting adjusting mechanism to freely lift and self-lock along the sliding direction of the tool seat frame.

In practical application, the machine tool seat is provided with the through hole, the screw rod is movably sleeved in the through hole, the through hole is used for penetrating through the screw rod, and the screw rod and the through hole cannot interfere with each other. One end of a screw rod is rotatably assembled on the tool rest base, the screw rod can rotate relative to the tool rest base, a nut matched with the screw rod is arranged at the other end of the screw rod, and the nut is rotatably assembled on the machine tool base through a bearing. When the processing stroke of the tool needs to be adjusted, a worker can do sliding lifting motion on the tool rest seat relative to the machine tool seat by screwing the nut and under the relative action of the nut and the screw rod, so that the stroke of the whole tool rest can be flexibly changed, and the tool on the tool rest seat can also adapt to processing column parts of different specifications.

Example 2

On the basis of the extended stroke tool rest of the vertical lathe provided in this embodiment 1, in order to further improve the self-locking property after adjusting the tool rest base, the extended stroke tool rest provided in this embodiment is provided with a locking mechanism for unidirectionally limiting the nut. In practical use, as shown in fig. 4, the locking mechanism includes: the ratchet wheel arranged on the outer circumference of the nut and the ring seat sleeved outside the nut are hinged to be provided with a locking block, and the locking block is provided with a spring for driving the locking block to reset.

As shown in fig. 5, if the nut needs to be rotated to adjust the machining stroke of the tool, the nut is rotated counterclockwise, and the locking block does not block the rotational movement of the ratchet wheel in the counterclockwise rotation process, at this time, the nut can normally rotate to realize the descending movement of the screw rod, so as to lengthen the machining stroke of the tool on the tool rest; after the nut is rotated to a proper position, the locking block is clamped into the ratchet of the ratchet wheel under the action of the spring to lock the clockwise rotation of the nut, at the moment, in the machining process of the cutter, the nut cannot rotate due to the influence of external factors (such as self vibration of a machine tool, mistaken touch of workers and the like), and the screw cannot loosen, so that the machining precision of the cutter is effectively guaranteed.

On the contrary, as shown in fig. 6, when the nut needs to be rotated clockwise, since the locking block can block the rotation of the ratchet wheel, at this time, the nut cannot rotate normally to realize the ascending movement of the screw rod, at this time, the worker can insert a bolt into the corresponding bolt hole, the bolt blocks the locking block, so as to prevent the ratchet wheel from being contacted with the nut, after the nut is rotated to a proper position (the cutter is also lifted to a proper position, the length of the tool rest can meet the requirement of a worker), the bolt is loosened, the locking block is clamped into the ratchet of the ratchet wheel under the action of the spring, the clockwise rotation of the nut can be locked, at the moment, the whole length of the tool rest is adjusted to a proper length, in the machining process of the cutter, the nut cannot rotate due to the influence of external factors, so that the screw cannot loosen, and the machining precision of the cutter can be effectively guaranteed.

The present invention is not limited to the above-mentioned optional embodiments, and any other products in various forms can be obtained by anyone under the teaching of the present invention, and any changes in the shape or structure thereof, all the technical solutions falling within the scope of the present invention, are within the protection scope of the present invention.
