Description

Technical Field

[0001] This invention relates to the field of lathe accessories technology, specifically to an adjustable taper tool holder, a taper hole machining device, and a leveling method thereof. Background Technology

[0002] When machining tapered holes, a reamer is placed in the main body to perform tapered hole machining. For different tapered hole sizes, tapered hole machining is generally achieved by customizing non-standard taper (such as 1:10, 1:8, 1:6, etc.) reamers.

[0003] However, during the machining process, situations often arise where the reamer's machining angle needs to be offset to a certain extent. Since the main body of a typical machining center is a standard part, the angle cannot be adjusted, and the corresponding standard tool holder is also set vertically around its axis. Standard tool holders and reamers are difficult to use, and different taper reamers need to be customized for different taper and diameter. Taper hole machining is difficult to achieve with standardized tools. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of this invention is to provide an adjustable taper tool holder, a tapered hole machining device and a leveling method thereof, so as to solve the problem of difficulty in machining tapered holes with different tapers and different diameters in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] On the one hand, an adjustable taper tool holder is provided, comprising:

[0007] The main body has one end for connection to the drive mechanism and the other end is provided with multiple mounting holes for mounting milling cutters. The axis of each mounting hole is at a different mounting angle to the rotation axis of the main body. Multiple leveling holes are circumferentially spaced on the side wall of the main body.

[0008] A bolt, having at least one bolt, is threadedly connected to the aforementioned leveling hole for adjusting the dynamic balance of the aforementioned main body.

[0009] In some optional embodiments, the above-mentioned mounting holes are provided in three locations, and the mounting angles are 2°51′, 3°34′ and 4°05′ respectively.

[0010] In some alternative embodiments, a plurality of the aforementioned mounting holes are evenly spaced on the aforementioned main body.

[0011] In some optional embodiments, the leveling holes are provided in multiple sets, each set of leveling holes is spaced apart along the axial direction of the main body, and multiple leveling holes in each set are spaced apart along the circumferential direction of the main body.

[0012] In some alternative embodiments, the aforementioned bolts have different weights.

[0013] In some alternative embodiments, the main body is a cylinder with chamfered ends.

[0014] Secondly, a tapered hole machining apparatus is provided, comprising:

[0015] The main body has one end for connection with the drive mechanism and the other end is provided with multiple mounting holes. The axis of each mounting hole is at a different mounting angle to the rotation axis of the main body. Multiple leveling holes are circumferentially spaced on the side wall of the main body.

[0016] A bolt, having at least one bolt, is threadedly connected to the aforementioned leveling hole for adjusting the dynamic balance of the aforementioned main body.

[0017] The milling cutter is detachably connected to the aforementioned mounting hole.

[0018] In some alternative embodiments, the main body is connected to the drive mechanism via a connecting part.

[0019] In some optional embodiments, the connecting part is frustum-shaped, with its large-diameter end connected to the end of the main body that is away from the end connected to the milling cutter, and its small-diameter end used to connect to the drive mechanism.

[0020] Thirdly, a leveling method for a tapered hole machining apparatus is provided, for leveling the aforementioned tapered hole machining apparatus, comprising the following steps:

[0021] Select the appropriate mounting hole to install the milling cutter according to the required taper of the tapered hole;

[0022] Measure the dynamic balance of the tapered hole machining device. When the dynamic balance of the tapered hole machining device does not meet the requirements, install bolts of corresponding weight at the corresponding positions of the main body until the dynamic balance meets the requirements.

[0023] Compared with the prior art, the advantages of the present invention are as follows: By opening multiple mounting holes at intervals along the axial direction at the end of the main body, and making the angle between the mounting holes and the center line different preset angles, the appropriate mounting hole can be selected to install the milling cutter according to the machining requirements of tapered holes with different taper, so that the main body and the milling cutter are at a set angle; by opening multiple leveling holes on the side wall of the main body and configuring corresponding bolts to detachably connect with the leveling holes, the dynamic balance of the main body can be adjusted, solving the problem of lateral force caused by the deviation of the axis when the main body rotates at a set angle with the milling cutter, so that the tool can be adjusted according to different taper machining requirements, and the application range is wide.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, in the first aspect, an adjustable taper tool holder is provided, including a main body 1 and a bolt 2. One end of the main body 1 is used to connect to a drive mechanism, and the other end is provided with a plurality of mounting holes 11 for mounting milling cutters 3. The axis of each of the mounting holes 11 is at a different mounting angle to the axis of rotation of the main body 1. A plurality of leveling holes 12 are circumferentially spaced on the side wall of the main body 1. The bolt 2 is provided with at least one bolt, which is threadedly connected to the leveling hole 12 for adjusting the dynamic balance of the main body 1.

[0031] It is understood that one end of the main body 1 is connected to the drive mechanism, and the other end is connected to the milling cutter 3. When the drive mechanism starts working, the main body 1 rotates, driving the milling cutter 3 to rotate and thus machining a tapered hole. Therefore, mounting holes 11 with different mounting angles are provided on the main body 1, and the milling cutter 3 is installed in the mounting holes 11. Since the axis of the mounting hole 11 is at an angle to the axis of rotation of the main body 1, when the milling cutter 3 rotates, the milling cutter 3 is at an angle to the main body 1, thereby machining a tapered hole with a taper.

[0032] Since the milling cutter 3 is not on the axis of the main body 1, an imbalance will occur when the drive unit rotates the main body 1 and the milling cutter 3. The main body 1 and the milling cutter 3 will experience lateral vibration, and the milling cutter 3 will be subjected to unnecessary dynamic loads. At this time, a leveling hole 12 is opened on the main body 1. By installing bolts 2 on the leveling hole 12, the dynamic balance of the main body 1 after the milling cutter 3 is installed is corrected, thereby adjusting the position of the center of gravity of the tool holder. That is, dynamic balance is achieved by removing or counterweighting.

[0033] The purpose of this design is to allow the milling cutter 3 to be installed in the corresponding mounting hole 11 when machining tapered holes of different tapers, thus eliminating the need to customize different special tapered reamers or milling cutters according to different tapered holes, thereby reducing machining costs.

[0034] In this example, the taper corresponding to the different mounting holes 11 is marked on the main body 1 to facilitate installation.

[0035] In some optional embodiments, the mounting holes 11 are provided in three locations, with mounting angles of 2°51′, 3°34′ and 4°05′ respectively.

[0036] It is understandable that the number and angle of the mounting holes 11 on the main body 1 are determined by the different taper angles of the tapered holes to be machined as needed. In this example, three mounting holes with different angles of 2°51′, 3°34′, and 4°05′ are made according to the commonly used taper angles of 1:10, 1:8, and 1:7. The mounting angle can be determined according to the rotation angle corresponding to the taper in the commonly used taper table.

[0037] In some alternative embodiments, a plurality of the aforementioned mounting holes 11 are evenly spaced on the aforementioned main body 1.

[0038] In this example, multiple mounting holes 11 are arranged around the rotation axis of the main body 1, and the mounting holes 11 are opened to a preset depth to ensure the stability of the milling cutter 3 installation.

[0039] In some optional embodiments, the leveling holes 12 are provided in multiple sets, each set of leveling holes 12 is spaced apart along the axial direction of the main body 1, and multiple leveling holes 12 in each set are spaced apart along the circumferential direction of the main body 1.

[0040] The number, position, and spacing of the leveling holes 12 can be specifically set according to the actual needs of use. In this example, the leveling holes 12 are provided in three sets with equal spacing.

[0041] In some alternative embodiments, the plurality of bolts 2 described above have different weights.

[0042] It is understood that bolt 2 is used to install on different leveling holes 12, so bolt 2 can be configured with different weights to select the appropriate weight of bolt for counterweight as required.

[0043] In some alternative embodiments, the main body 1 is a cylinder with chamfered ends.

[0044] It is understandable that the main body 1 is designed as a cylinder with uniform mass, which facilitates dynamic balance adjustment. In this example, the end of the main body 1 near the end connected to the milling cutter 3 has a chamfer extending in the direction of the milling cutter 3.

[0045] Secondly, a tapered hole machining device is also provided, including a main body 1, a bolt 2, and a milling cutter 3. One end of the main body 1 is used to connect to a drive mechanism, and the other end is provided with a plurality of mounting holes 11. The axis of each mounting hole 11 is at a different mounting angle to the rotation axis of the main body 1. A plurality of leveling holes 12 are circumferentially spaced on the side wall of the main body 1. The bolt 2 is provided with at least one bolt and is threadedly connected to the leveling hole 12 for adjusting the dynamic balance of the main body 1. The milling cutter 3 is detachably connected to the mounting hole 11.

[0046] It is understood that the tapered hole machining device includes the aforementioned adjustable taper tool holder and a milling cutter 3. Specifically, one end of the main body 1 is connected to the drive mechanism, and the other end is detachably connected to the milling cutter 3. When the drive mechanism starts working, the main body 1 rotates, driving the milling cutter 3 to rotate and thus machining the tapered hole. Therefore, mounting holes 11 with different mounting angles are provided on the main body 1. The milling cutter 3 is installed in the mounting holes 11. Since the axis of the mounting holes 11 is at an angle to the axis of rotation of the main body 1, when the milling cutter 3 rotates, the milling cutter 3 is at an angle to the main body 1, thereby machining a tapered hole with a taper.

[0047] In some alternative embodiments, the main body 1 is connected to the drive mechanism via the connecting part 4.

[0048] In this example, the drive mechanism is a machine tool, and the main body 1 is detachably connected to the machine tool via the connecting part 4.

[0049] In some alternative embodiments, the connecting part 4 is frustum-shaped, with its large-diameter end connected to the end of the main body 1 away from the end connected to the milling cutter 3, and its small-diameter end used to connect to the drive mechanism.

[0050] The connecting part 4 is shaped like a frustum, and its smaller diameter end is connected to the drive mechanism for easy installation. Similarly, to facilitate the adjustment of the dynamic balance of the tapered hole machining device, both the main body 1 and the connecting part 4 are of uniform mass.

[0051] It is understandable that since dynamic balance cannot be completely zero, this can be overcome by increasing the diameter of the milling cutter and improving the rigidity of the main body and the milling cutter.

[0052] Thirdly, a leveling method for a tapered hole machining apparatus is also provided, for leveling the aforementioned tapered hole machining apparatus, comprising the following steps:

[0053] Select the appropriate mounting hole 11 to install the milling cutter 3 according to the required taper of the tapered hole.

[0054] The dynamic balance of the tapered hole machining device is measured. When the dynamic balance of the tapered hole machining device does not meet the requirements, bolts 2 of corresponding weight are installed at the corresponding positions of the main body 1 until the dynamic balance meets the requirements.

[0055] In this example, a dynamic balancing instrument is used to measure the dynamic balance of the tapered hole machining device. The dynamic balancing instrument will display the amount of imbalance and the angular position of the imbalance on the main body.

[0056] For example, the milling cutter 3 is installed on one of the mounting holes 11, and a dynamic balancing machine is used for measurement. Based on the position and weight displayed on the dynamic balancing machine, the bolt 2 of the corresponding weight is installed on the leveling hole 12 at the corresponding position. If the calculated counterweight angle is inconvenient to operate in the actual equipment, the counterweight can be decomposed. Enter two decomposition angles, and click "Decompose Counterweight" to decompose the counterweight to the other two angles. Then check the balance result. After adding the counterweight, check the result. If the result does not meet the required balance, click the "Further Balance" button to recalculate the counterweight and further correct it until the dynamic balance condition is met.

[0057] This invention discloses an adjustable taper tool holder, a tapered hole machining device, and a leveling method thereof. By providing multiple mounting holes on the main body and setting the mounting holes at different mounting angles to the rotation axis of the main body, a milling cutter can be installed in different mounting holes to machine tapered holes of different tapers. This allows for adaptation to different tapered hole machining requirements without replacing the tapered hole machining device, eliminating the need to customize multiple tapered hole machining devices and reducing machining costs. By opening multiple leveling holes on the side wall of the main body and configuring bolts of different weights to be threaded into the leveling holes, the dynamic balance of the tapered hole machining device can be adjusted, avoiding vibration and other problems during machining.
