Description

Technical Field

[0001] The utility model belongs to the technical field of tool holders, and particularly relates to an adjustable tool holder. Background Technique

[0002] A tool holder, also known as a tool rest or turret, is a component installed on a lathe for fixing a turning tool. It is an indispensable part of turning machining, ensuring that the turning tool can be stably and accurately positioned at the required position for machining the workpiece. The design of the tool holder usually allows adjustment of the position and angle of the turning tool to adapt to different machining requirements, such as turning the outer diameter, turning the inner hole, grooving, facing, etc. During the use of the existing tool holder, after installing the turning tool, it is often found that the height of the tool is inconsistent with the center height of the part to be machined, which requires adjustment of the height of the turning tool. The existing adjustment device requires manual assistance for adjustment, thus affecting the overall use efficiency of the device and the replacement efficiency of the turning tool.

[0003] For example, the utility model with the publication number CN215615175U discloses a height-adjustable tool holder, including an upper tool holder and a lower tool holder. A tool groove is provided on the upper tool holder, and an inclined guide block is provided on the lower surface of the upper tool holder. An inclined guide groove is provided on the upper surface of the lower tool holder. The inclined guide block is slidably arranged in the inclined guide groove. As the inclined guide block slides and is limited to different positions in the inclined guide groove, the height of the tool groove is different. During the use of this device, when adjusting the height of the device, the adjustment efficiency is low, which will affect the machining of parts, thus affecting the working condition of the device during use and the overall use efficiency of the device. Therefore, an adjustable tool holder is proposed. Summary of the Utility Model

[0004] In view of this, in order to overcome the deficiencies of the prior art, the utility model provides an adjustable tool holder, which can not only adjust the device in the horizontal direction, but also better adjust the height direction by a motor, thereby improving the overall use condition and overall convenience efficiency of the device.

[0005] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: An adjustable turning tool holder includes a bottom plate. A lifting mechanism is provided on the top of the bottom plate. The lifting mechanism includes fixing blocks arranged on the front and rear sides of the top of the bottom plate. A chute with an upward opening is arranged in the middle of the two fixing blocks. Two sliders are respectively arranged inside the two chutes. U-shaped plates are respectively arranged on the tops of the four sliders. Connecting rods are respectively and hingedly arranged inside the four U-shaped plates. The tops of the two connecting rods on the front side and the tops of the two connecting rods on the rear side are respectively and commonly hingedly arranged with a U-shaped frame. The tops of the two U-shaped frames are commonly provided with a top plate. A bidirectional lead screw passing through the sliders is respectively arranged inside the two chutes. First rotating motors connected to the bidirectional lead screw are respectively arranged on the right sides of the two sliders. The first rotating motor and the bidirectional lead screw are connected through a coupling. A lateral moving mechanism is arranged at the bottom of the bottom plate.

[0006] As a further improvement of the present utility model, the lateral moving mechanism includes two fixing plates arranged on the front and rear sides of the bottom of the bottom plate. Slide grooves are respectively arranged at the bottoms of the two fixing plates. Slide rods are respectively arranged at the bottoms of the two slide grooves. Cross bars are respectively arranged at both ends of the two slide rods. Guide plates are respectively arranged on the left and right sides of the bottom of the bottom plate. A threaded rod passing through the guide plate is arranged at the front side between the two cross bars. A guide rod passing through the guide plate is arranged at the rear side between the two cross bars. A second rotating motor connected to the threaded rod is arranged at the right end of the right cross bar. A longitudinal moving mechanism is arranged on the top of the top plate.

[0007] As a further improvement of the present utility model, the longitudinal moving mechanism includes guide blocks arranged on the left and right sides of the top of the top plate. A V-shaped groove is arranged in the middle of the left guide block. A circular groove with an upward opening is arranged in the middle of the right guide block. Connecting plates are respectively arranged at the front and rear ends of the top of the top plate. A V-shaped block is arranged at the top of the V-shaped groove. A circular block is arranged inside the circular groove. A moving plate is commonly arranged at the tops of the V-shaped block and the circular block. A connecting block is arranged in the middle of the bottom of the moving plate. A lead screw passing through the connecting block is commonly arranged in the middle of the two connecting plates. A third rotating motor connected to the lead screw is arranged at the front end of the front connecting plate. The third rotating motor and the lead screw are connected through a coupling.

The switch is electrically connected to the first rotating motor, the second rotating motor, and the third rotating motor. Mounting plates are respectively arranged at the four corners of the two cross bars. Round holes are respectively arranged on the four mounting plates. Screws are respectively arranged in the four round holes.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] First, start the rotation of the first rotary motor to drive the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw drives the slider to move inside the chute, thereby driving the connecting rod inside the U-shaped plate to rotate, and then driving the end of the connecting rod away from the slider to rotate inside the U-shaped frame, so that the U-shaped frame drives the top plate to rise and fall, thereby increasing the height of the tool holder and facilitating the adjustment of the tool height.

[0011] Second, start the second rotary motor. The rotation of the second rotary motor drives the threaded rod to drive the guide plate to move in the left-right direction inside the cross bar, so that the bottom plate on the top of the guide plate moves in the left-right direction. At this time, the slide bar slides inside the sliding groove, making the operation of the device more stable.

[0012] Third, start the third rotary motor. The rotation of the third rotary motor drives the lead screw to rotate inside the connecting plate. The rotation of the lead screw drives the connecting block to move back and forth, so that the moving plate moves in the front-back direction. The V-shaped block slides inside the V-shaped groove, and the circular block slides inside the circular groove, making the moving plate move more smoothly and with a smaller displacement.

[0013] Fourth, when the tool needs to be changed, rotate the rotary tool block, which can facilitate the replacement of the tool. BRIEF DESCRIPTION OF THE DRAWINGS
