Description

Technical Field

[0001] This utility model relates to the field of milling and turning equipment technology, and in particular to an adjustable tool holder magazine for a vertical machine tool. Background Technology

[0002] The background technology of power turrets originated from the improvement of traditional lathe tool post. It has gradually evolved into a turret with a power source, which can independently provide the main motion and feed motion for the tool to complete various machining processes such as milling and drilling. The emergence of power turrets has greatly improved the machining efficiency and flexibility of machine tools and has become one of the core technologies in milling and turning composite machine tools.

[0003] During the process of disassembling and replacing the tool holder of the power turret, the fit between the tool holder and the turret is so tight that even if the screws on the tool holder are removed, it is difficult to remove the tool holder. Often, it is necessary to use a screwdriver or other tools to pry the frame off with brute force. During the prying process, a large vibration is often generated, which leads to a decrease in the overall precision of the turret. Based on this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vertical adjustable tool holder magazine that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable tool holder magazine for a vertical machine tool includes a support platform on which a fixture and a frame are fixedly connected. It also includes a tool turret fixedly connected to the movable end of the frame, and a tool holder body fixedly connected to the turret. A movable plate is slidably connected inside the turret, and a push plate is slidably connected to the turret. Multiple air passages are provided on the turret. When the push plate moves outward, it pushes the movable plate to move together, pushing the tool holder body out of the turret. When the push plate is pushed back into the turret by the tool holder body, the air passages clean the inner surface of the tool holder body by blowing air.

[0007] Preferably, a fixing plate is fixedly connected to the turret, and a rotating bolt is rotatably connected to the fixing plate.

[0008] Furthermore, the rotating bolt is threadedly connected to a sliding baffle, and a sliding rod is slidably connected inside the sliding baffle, the sliding rod being fixedly connected to the push plate.

[0009] Preferably, the turret has a guide groove, and the push plate is slidably connected to the guide groove.

[0010] Preferably, the turret has a cavity, the movable plate is slidably connected in the cavity, and the cavity is connected to the air passage. When the movable plate compresses the air in the cavity, the gas is discharged through the air passage.

[0011] Preferably, a limit rod and a push rod are fixedly connected to the movable plate, and the limit rod is slidably connected to the turret.

[0012] Furthermore, a limit block is slidably connected inside the push rod, and a compression spring is connected between the limit block and the turret.

[0013] Preferably, the turret has a limiting groove.

[0014] Compared with the prior art, this utility model provides an adjustable tool holder magazine for vertical machine tools, which has the following advantages:

[0015] 1. The adjustable tool holder magazine of this vertical machine tool can push the movable plate out by rotating the rotating bolt, thereby pushing out the tool holder body. This can avoid the vibration and displacement of the tool turret caused by brute force disassembly, which would lead to a decrease in turning accuracy.

[0016] 2. The adjustable tool holder magazine of this vertical machine tool, when the tool holder body is installed, pushes the movable plate to reset and squeezes the air inside the cavity to discharge, which helps to clean the dust and debris on the surface of the tool holder body, and avoids the tool holder body and the turret not being able to fully engage due to debris on the surface of the tool holder body.

[0017] The parts not covered in this device are the same as or can be implemented using existing technology. This utility model can push out the tool holder body, avoiding the impact of brute force disassembly on the tool turret, such as vibration and displacement, which would lead to a decrease in turning accuracy. At the same time, it can assist in cleaning the dust and debris on the surface of the tool holder body during installation, preventing the tool holder body and the tool turret from not being able to fully engage due to debris adhering to the surface of the tool holder body.

[0025] 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.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1: Refer to Figures 1-6 An adjustable tool holder magazine for a vertical machine tool includes a support platform 1, on which a clamp 11 and a frame 12 are fixedly connected. It also includes a tool turret 2 fixedly connected to the movable end of the frame 12, and a tool holder body 4 fixedly connected to the tool turret 2. A movable plate 3 is slidably connected inside the tool turret 2, and a push plate 24 is slidably connected to the tool turret 2. Multiple air passages 27 are provided on the tool turret 2. When the push plate 24 moves outward, it pushes the movable plate 3 to move together, pushing the tool holder body 4 out of the tool turret 2. When the push plate 24 is pushed back into the tool turret 2 by the tool holder body 4, the air passages 27 clean the inner surface of the tool holder body 4 by blowing air.

[0028] In this invention, the frame 12 can drive the turret 2 to perform multi-axis movement to turn the workpiece clamped on the fixture 11. The tool is fixed on the tool holder body 4, which is bolted to the turret 2. The tool holder body 4 is generally tightly fitted to the turret 2. When the bolts on the tool holder body 4 are removed, normally the tool holder body 4 would be pried out by brute force or by using a tool. However, this device can push the movable plate 3 outward by moving the push plate 24. During the pushing process, the movable plate 3 will push the tool holder body 4 outward and separate it from the turret 2, thereby avoiding the vibration and displacement of the turret 2 caused by brute force disassembly, which would lead to a decrease in turning accuracy.

[0029] When installing the tool holder body 4, the tool holder body 4 will push the movable plate 3 to reset. During the reset process, the movable plate 3 will compress air and discharge it from the air passage 27. The discharged air can be blown vertically onto the contact surface between the tool holder body 4 and the turret 2, thereby assisting in cleaning the dust and debris on the surface of the tool holder body 4 and preventing the tool holder body 4 from being unable to fully engage with the turret 2 due to debris adhering to the surface of the tool holder body 4.

[0030] Example 2: Refer to Figures 1-6 Similar to Embodiment 1, but with a further improvement: a fixed plate 21 is fixedly connected to the turret 2, a rotating bolt 22 is rotatably connected to the fixed plate 21, a sliding baffle 23 is threadedly connected to the rotating bolt 22, a sliding rod 25 is slidably connected inside the sliding baffle 23, the sliding rod 25 is fixedly connected to the push plate 24, a guide groove 26 is provided on the turret 2, the push plate 24 is slidably connected to the guide groove 26, a cavity 29 is provided inside the turret 2, a movable plate 3 is slidably connected inside the cavity 29, the cavity 29 is connected to the air passage 27, when the movable plate 3 compresses the air in the cavity 29, the gas is discharged through the air passage 27, a limit rod 32 and a push rod 31 are fixedly connected to the movable plate 3 respectively, the limit rod 32 is slidably connected to the turret 2, a limit block 33 is slidably connected inside the push rod 31, a compression spring 34 is connected between the limit block 33 and the turret 2, and a limit groove 28 is provided on the turret 2.

[0031] In this utility model, the user can use an Allen wrench to rotate the rotating bolt 22, thereby driving the sliding baffle 23 and the push plate 24 to move together, which in turn allows the push plate 24 to push the limiting block 33 and the movable plate 3 to move outward and push out the knife holder body 4.

[0032] The push plate 24 is slidably connected to the sliding baffle 23 via the sliding rod 25. During the movement of the sliding baffle 23 and the push plate 24, under the action of the guide groove 26, the push plate 24 will slide upward after moving a certain distance, thereby disengaging from the contact with the limit block 33, which makes it convenient for the user to quickly press and reset the movable plate 3 when installing the tool holder body 4.

[0033] The movable plate 3 pushes the tool holder body 4 out through the limiting rod 32. During installation, the tool holder body 4 can also push the movable plate 3 back into position through the limiting rod 32. The limiting rod 32 can prevent the movable plate 3 from shifting when it is pushed.

[0034] When the user rotates the rotating bolt 22 to reset the sliding baffle 23 and the push plate 24, the push plate 24 will move down by squeezing the inclined surface of the limiting block 33 during the reset process, so that the limiting block 33 will not obstruct the reset of the push plate 24.

[0035] A guide block is provided on the tool holder body 4, which corresponds to the limiting groove 28, so that the two can be engaged when the tool holder body 4 is installed. When the tool holder body 4 is installed, the tool holder body 4 will press the movable plate 3 to reset. During the reset process, the movable plate 3 will compress the space in the cavity 29, so that the air in the cavity 29 can be discharged outward through the air passage 27, thereby enabling the surface of the tool holder body 4 to be cleaned by blowing air.

[0036] When disassembling, the user first removes the bolts fixing the tool holder body 4, and then uses an Allen wrench to turn the rotating bolt 22 to drive the sliding baffle 23 and push plate 24 to push out the movable plate 3, thereby causing the movable plate 3 to push out the tool holder body 4. During installation, the user can directly fasten the tool holder body 4 onto the turret 2 through the limiting groove 28. During the fastening process, the tool holder body 4 pushes the movable plate 3 back into position. Then, the user fixes the tool holder body 4 onto the turret 2 with bolts, and rotates the rotating bolt 22 to reset the sliding baffle 23 and push plate 24.

[0037] 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.
