Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a special lathe for machining rubber waterline device components. Background Technology

[0002] The CS6140 series general-purpose lathes can handle various turning operations, including turning internal and external cylindrical surfaces, end faces, and other rotating surfaces. A turning tool is a cutting tool with a cutting edge used in turning operations. Currently, the common practice for installing and removing turning tools is to use a square tool holder and tighten it with bolts. This method is cumbersome for tool changes, and the rotation of the bolts during tightening can cause tool misalignment, resulting in chip angle deviation, affecting cutting quality, and accelerating tool wear. Utility Model Content

[0003] The purpose of this invention is to solve the problem of reduced accuracy caused by the tool holder easily shifting during tool installation in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A special lathe for processing rubber waterline device components includes a lathe and a tool holder with an angle rotation function. The tool holder is equipped with a handle for locking the rotation angle of the tool holder. The tool holder is equipped with a reference frame, which is square in shape. A fixing plate is provided on the reference frame. A pre-compression mechanism is provided below the fixing plate and is sleeved on the reference frame. A locking device is provided on the reference frame and is connected to the pre-compression mechanism. Both the locking device and the pre-compression mechanism are sleeved on the tool holder.

[0006] Preferably, the pre-compression mechanism includes a movable pressure plate located below the fixed plate and sliding relative to the fixed plate. An elastic mechanism is provided between the movable pressure plate and the reference frame. The top of the movable pressure plate is connected to the locking device. The elastic mechanism includes a first spring and a second spring. The first spring is located between the movable pressure plate and the locking device, and the second spring is located between the movable pressure plate and the reference frame. The elastic force of the first spring is greater than that of the second spring. A plurality of guide rods are provided at the bottom of the movable pressure plate, and a plurality of straight holes are provided on the reference frame. The number of straight holes matches the number of guide rods, and the guide rods are slidably connected to the straight holes.

[0007] Preferably, a guide block is provided at the edge of the movable pressure plate, and a limiting block is provided between the guide block and the movable pressure plate.

[0008] Preferably, the limiting block slides relative to the movable pressure plate, and an adjusting rod passes through the side of the movable pressure plate, with one end of the adjusting rod connected to the limiting block.

[0009] Preferably, the locking device includes a threaded sleeve, which is fixed on the reference frame. An annular knob is fitted on the threaded sleeve and threadedly connected to the threaded sleeve. The bottom of the annular knob is connected to the movable pressure plate through a first spring. Both the first spring and the second spring are fitted on the threaded sleeve.

[0010] Preferably, the annular knob is provided with an auxiliary bracket.

[0011] The beneficial effects proposed by this utility model are as follows:

[0012] When the worker installs the cutting tool on the tool holder, the tool is first placed against the reference frame. Then the pre-compression mechanism pre-compresses the tool, at which point the tool is fixed relative to the reference frame. Then the locking device is activated, and the locking device drives the pre-compression mechanism to continuously increase the pressure on the tool until the locking device locks. The pre-compression mechanism completely compresses the tool, so that the tool is placed against the reference frame and locked in place. In the above process, the pre-compression mechanism initially fixes the tool, making the tool fit against the mounting reference surface of the reference frame. During this process, the pre-compression mechanism moves downward until it contacts the tool. The locking force applied by the locking device acts on the pre-compression mechanism and does not directly act on the tool. Compared with traditional screw locking, where screws need to rotate continuously during tool locking, and when rotating the screw, a rotational force is applied to the tool, causing the tool to shift on the tool holder, the pre-compression mechanism achieves initial fixation of the tool, improving the installation accuracy of the tool on the tool holder. Furthermore, the locking device acting on the pre-compression mechanism reduces the direct contact between the locking device and the tool, thus reducing the problem of tool installation position shift.

[0020] 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.

[0021] Reference Figures 1 to 6A special lathe for processing rubber waterline device components includes a lathe 1 and a tool holder 2 with an angle rotation function. The tool holder 2 is provided with a handle 3 for locking the rotation angle of the tool holder 2. The tool holder 2 is provided with a reference frame 5, which is square in shape. The reference frame 5 is provided with a fixing plate 6. A pre-compression mechanism is provided below the fixing plate 6 and is sleeved on the reference frame 5. The reference frame 5 is provided with a locking device, which is connected to the pre-compression mechanism. Both the locking device and the pre-compression mechanism are sleeved on the tool holder 2. Specifically, the lathe 1 is a CS6140 series ordinary lathe. When the worker installs the tool 4 on the tool holder 2, the tool 4 is first placed against the reference frame 5. Then, the pre-pressing mechanism pre-presses the tool 4. At this time, the tool 4 is fixed relative to the reference frame 5. Then, the locking device is activated. The locking device drives the pre-pressing mechanism to continuously increase the pressure on the tool 4 until the locking device locks. The pre-pressing mechanism completely compacts the tool 4, so that the tool 4 is placed against the reference frame 5 and locked and fixed. In the above process, the pre-pressing mechanism initially fixes the tool 4, making the tool 4 fit against the mounting reference surface of the reference frame 5. During this process, the pre-pressing mechanism moves downward until it contacts the tool 4. The locking force applied by the locking device acts on the pre-pressing mechanism and does not directly act on the tool 4. Compared with traditional screw locking, where screws need to rotate continuously during the locking process of the tool 4, and when the screw is rotated, it also applies a rotational force to the tool 4, causing the tool 4 to shift on the tool holder 2, the pre-pressing mechanism achieves the initial fixation of the tool 4, improving the installation accuracy of the tool 4 on the tool holder 2. Furthermore, by using the locking device on the pre-pressing mechanism, the direct contact between the locking device and the tool 4 is reduced, thus reducing the problem of tool 4 shifting its installation position.

[0022] It should be noted that, as described above, both the preload mechanism and the locking device bypass the structure of the angle rotation function in the tool post 2, and their operation does not affect the operation of the angle rotation function in the tool post 2. The angle rotation function in the tool post 2 is a common component in the CS6140 lathe and a technical method commonly used by those skilled in the art; it is existing technology and will not be described in detail here.

[0023] Specifically, the pre-compression mechanism includes a movable pressure plate 7 located below the fixed plate 6. The movable pressure plate 7 slides relative to the fixed plate 6. An elastic mechanism is provided between the movable pressure plate 7 and the reference frame 5. The top of the movable pressure plate 7 is connected to the locking device. The elastic mechanism includes a first spring 8 and a second spring 9. The first spring 8 is located between the movable pressure plate 7 and the locking device, and the second spring 9 is located between the movable pressure plate 7 and the reference frame 5. The elastic force of the first spring 8 is greater than that of the second spring 9. The bottom of the movable pressure plate 7 is provided with a plurality of guide rods 16. The reference frame 5 is provided with a plurality of straight holes 17. The number of straight holes 17 matches the number of guide rods 16, and the guide rods 16 are slidably connected to the straight holes 17. During the installation of the cutting tool 4 on the tool holder 2, the operator first applies an upward lifting force to drive the movable pressure plate 7 upward. Then, the cutting tool 4 is placed below the movable pressure plate 7, with one side of the cutting tool 4 in contact with the reference frame 5. Next, the lifting force applied to the movable pressure plate 7 is released. At this time, the movable pressure plate 7 moves downward under the action of the first spring 8 and acts on the cutting tool 4. Since the elastic force of the first spring 8 is greater than that of the second spring 9, the elastic force output by the first spring 8 can overcome the reverse elastic force generated by the second spring 9 and drive the movable pressure plate 7 to pre-press the cutting tool 4. After the pre-pressing is completed, the operator then drives the locking device to press and fix the cutting tool 4 onto the reference frame 5 using the movable pressure plate 7. During this process, the second spring 9 is compressed by the movable pressure plate 7 and stores its elastic force, while the first spring 8 is in a stretched state. When the locking device releases the locking force on the movable pressure plate 7, the second spring 9 releases its stored elastic force. At this time, the second spring 9 drives the movable pressure plate 7 to move upward, and the first spring 8 contracts synchronously. The movable pressure plate 7 releases the clamping state on the tool 4, and the operator can remove the tool 4 from the reference frame 5. This achieves quick assembly and disassembly of the tool 4, and the pre-pressing function can improve the installation accuracy of the tool 4. In the above description, during the up-and-down movement of the movable pressure plate 7, in order to reduce the rotation of the movable pressure plate 7 around its axis, the movable pressure plate 7 is limited in its rotation direction by the connection between the guide rod 16 and the straight hole 17, so that the movable pressure plate 7 can only move in a straight line up and down.

[0024] Specifically, a guide block 10 is provided at the edge of the movable pressure plate 7, and a limiting block 11 is provided between the guide block 10 and the movable pressure plate 7. The guide block 10 can assist the tool 4 in being placed on the reference frame 5 through the movable pressure plate 7. When the tool 4 is placed on the reference frame 5, it will deviate when pressed by the movable pressure plate 7. The limiting block 11 is added between the guide block 10 and the movable pressure plate 7. The limiting block 11 and the reference frame 5 form a limiting effect on the tool 4. When the locking device continuously drives and presses, it reduces the amplitude of the tool 4 shaking during the pressing process and improves the installation accuracy of the tool 4.

[0025] Specifically, the limiting block 11 slides relative to the movable pressure plate 7. An adjusting rod 12 passes through the side of the movable pressure plate 7, and one end of the adjusting rod 12 is connected to the limiting block 11. Because the cutters 4 vary in size, a fixed connection between the limiting block 11 and the movable pressure plate 7 cannot accommodate different cutters 4. Consequently, during pre-pressing, the cutter 4 may still wobble. Therefore, the limiting block 11 slides relative to the movable pressure plate 7. The distance between the limiting block 11 and the reference frame 5 is adjusted by the adjusting rod 12, which passes through the side of the movable pressure plate 7 and is threaded together. The operator rotates the adjusting rod 12, causing the limiting block 11 to move on the movable pressure plate 7. This achieves pre-pressing fixation for cutters 4 of different sizes. In the above description, the adjusting rod 12 and the limiting block 11 can be connected by bearings or other auxiliary components of annular rotating bodies, so that when the adjusting rod 12 rotates, the limiting block 11 will not rotate synchronously with the adjusting rod 12, and will be driven by the adjusting rod 12 to move linearly.

[0026] Specifically, the locking device includes a threaded sleeve 13, which is fixed on the reference frame 5. An annular knob 14 is fitted onto the threaded sleeve 13 and is threadedly connected to it. The bottom of the annular knob 14 is connected to the movable pressure plate 7 via a first spring 8. Both the first spring 8 and the second spring 9 are fitted onto the threaded sleeve 13. When the operator rotates the annular knob 14, it moves linearly along the axis on the threaded sleeve 13. At this time, the bottom of the annular knob 14 compresses the first spring 8 and drives the movable pressure plate 7 downwards until it presses against the tool 4. At this point, the first spring 8 is compressed and stores its elasticity. The pre-compression mechanism is locked and fixed as described above. When the pressure of the annular knob 14 on the movable pressure plate 7 is gradually released, the first spring 8 releases the stored elastic force. In this process, the elastic force released by the first spring 8 replaces the pressure of the annular knob 14 to press the cutter 4, which can effectively reduce the risk of the cutter 4 loosening and falling off when the locking device is released, and further improve the pre-compression effect on the cutter 4.

[0027] Specifically, the annular knob 14 is provided with an auxiliary frame 15. The auxiliary frame 15 is used to assist in tightening and loosening the annular knob 14. The auxiliary frame 15 is a round rod. The operator applies a pushing force to the auxiliary frame 15, so that the annular knob 14 can rotate on the threaded sleeve 13. Furthermore, the operator can also place an extended tube on the auxiliary frame 15 to save force during the tightening and loosening process.

[0028] 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.
