Description

Technical Field

[0001] This utility model relates to the field of irregular part processing technology, and in particular to a single-axis transmission tool angle head for irregular part processing. Background Technology

[0002] The demand for machining irregularly shaped parts, such as those with complex inclined surfaces, irregular hole systems, and irregular contours, is increasing. Due to their special structure, these parts often require cutting tools to operate at non-standard angles. However, traditional vertical or horizontal machining centers have fixed spindle directions, making it difficult to directly meet multi-angle machining requirements. Single-axis drive tool angle heads, as an important machine tool function extension component, can connect to the machining center spindle to change the cutting direction of the tool, enabling precise machining of specific parts of irregularly shaped parts. Their core function is to expand the machining range of the machine tool, reduce the number of workpiece clamping operations, and improve production efficiency while ensuring transmission stability and machining accuracy.

[0003] However, in the aforementioned prior art, the angle adjustment flexibility of the angle head is poor, and it can usually only achieve the switching of fixed angles (such as 45°, 90°). For the machining parts with non-standard angles on irregular parts, it is necessary to frequently change angle heads of different specifications or adjust the workpiece clamping posture, which not only increases the complexity of the operation process, but also easily causes positioning errors due to multiple clamping, reducing machining efficiency and dimensional accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a single-axis transmission tool angle head for machining irregularly shaped parts. It aims to solve the problem that the angle adjustment flexibility of the existing angle head is poor. It can usually only achieve the switching of fixed angles. For machining parts with non-standard angles on irregularly shaped parts, it is necessary to frequently change angle heads of different specifications or adjust the workpiece clamping posture. This not only increases the complexity of the operation process, but also easily causes positioning errors due to multiple clamping, reducing machining efficiency and dimensional accuracy.

[0005] To achieve the above objectives, this utility model provides a single-axis transmission tool angle head for machining irregularly shaped parts, including a mounting base, an assembly plate, a connecting housing, a bottom shell, a rotating head, a transmission shaft, a worm gear transmission mechanism, and multiple connecting components. The assembly plate is detachably connected to the mounting base and is located below the mounting base. The connecting housing is disposed below the assembly plate. The multiple connecting components are respectively connected to the assembly plate and the connecting housing. The bottom shell is detachably connected to the connecting housing and is located below the connecting housing. The worm gear transmission mechanism is rotatably connected to the connecting housing and the bottom shell and is located between the connecting housing and the bottom shell. The transmission shaft is rotatably connected to the connecting housing and is located on the inner sidewall of the connecting housing. The transmission shaft is detachably coupled to the worm gear transmission mechanism. The rotating head is detachably connected to the transmission shaft and is located at the end of the transmission shaft away from the worm gear transmission mechanism.

[0006] The single-axis transmission tool angle head used for machining irregularly shaped parts also includes a scale ring, which is disposed on the outer side wall of the connecting housing.

[0007] The single-axis transmission tool angle head for machining irregular parts also includes a locking spring, which is disposed on the inner side wall of the rotating head and contacts the transmission shaft.

[0008] The connecting assembly includes a countersunk hexagonal bolt and a trapezoidal block. The assembly plate has a trapezoidal groove that slides with the trapezoidal block. The assembly plate has a countersunk hole that rotates with the countersunk hexagonal bolt. The trapezoidal block has a threaded hole that threadedly engages with the countersunk hexagonal bolt.

[0009] This utility model discloses a single-axis transmission tool angle head for machining irregularly shaped parts. In use, the angle head is installed to the output end of the worm gear transmission mechanism by threading. The rotating head is inserted into the top of the transmission shaft and locked in place, then drives the transmission shaft to rotate. The worm gear transmission mechanism converts axial rotation into lateral rotation, thereby realizing the rotation of the angle head. This makes the angle head more adaptable to workpieces of different depths, and the tool can easily machine irregularly shaped parts. The connecting assembly is used to install the connecting housing. This method solves the problem of poor angle adjustment flexibility of angle heads, which usually only allow for switching to fixed angles. For machining non-standard angle parts on irregularly shaped parts, it is necessary to frequently change angle heads of different specifications or adjust the workpiece clamping posture, which not only increases the complexity of the operation process but also easily causes positioning errors due to multiple clamping, reducing machining efficiency and dimensional accuracy.

Detailed Implementation

[0015] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0016] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the single-axis transmission tool angle head for machining irregularly shaped parts according to this utility model. Figure 2 This is a front view of the single-axis transmission tool angle head for machining irregularly shaped parts according to this utility model. Figure 3 This is the utility model Figure 2 A sectional view along line AA.

[0017] This utility model provides a single-axis transmission tool angle head for machining irregularly shaped parts, including a mounting base 101, an assembly plate 102, a connecting housing 103, a bottom shell 104, a rotating head 105, a transmission shaft 106, a worm gear transmission mechanism 107, a scale ring 108, a locking spring 109, and multiple connecting components. The connecting components include countersunk hexagonal bolts 110 and trapezoidal blocks 111. The assembly plate 102 has a trapezoidal groove 112 and a countersunk hole 113. The trapezoidal block 111 has a threaded hole 114.

[0018] The assembly plate 102 is detachably connected to the mounting base 101 and is located below the mounting base 101. The connecting housing 103 is disposed below the assembly plate 102. A plurality of connecting components are respectively connected to the assembly plate 102 and the connecting housing 103. The bottom shell 104 is detachably connected to the connecting housing 103 and is located below the connecting housing 103. The worm gear transmission mechanism 107 is rotatably connected to the connecting housing 103 and the bottom shell 104 and is located between the connecting housing 103 and the bottom shell 104. The transmission shaft 106 is rotatably connected to the connecting housing 103 and is located on the inner sidewall of the connecting housing 103. The transmission shaft 106 is detachably engaged with the worm gear transmission mechanism 107. The rotating head 105 is detachably connected to the transmission shaft 106 and is located at the end of the transmission shaft 106 away from the worm gear transmission mechanism 107.

[0019] In this embodiment, the angle head is installed to the output end of the worm gear transmission mechanism 107 by tightening it with a thread. The rotating head 105 is inserted into the top of the transmission shaft 106 and locked in place. Then, the transmission shaft 106 is rotated. The worm gear transmission mechanism 107 converts the axial rotation into lateral rotation, thereby realizing the rotation of the angle head. This makes the angle head more adaptable to workpieces of different depths, and the cutting tool can easily process irregular parts. The connecting component is used to install the connecting housing 103. This method solves the problem of poor angle adjustment flexibility of the angle head, which can usually only achieve fixed angle switching. For non-standard angle processing parts on irregular parts, it is necessary to frequently change angle heads of different specifications or adjust the workpiece clamping posture. This not only increases the complexity of the operation process, but also easily causes positioning errors due to multiple clamping, reducing processing efficiency and dimensional accuracy.

[0020] Furthermore, the scale ring 108 is disposed on the outer side wall of the connecting housing 103.

[0021] In this embodiment, the scale ring 108 is used for angle and position calibration, helping operators to accurately determine parameters such as the rotation angle and displacement of the components, ensuring that the device operates accurately according to design requirements; in situations where precise control of the rotation angle is required, the mechanical action can be precisely controlled by reading the value of the scale ring 108.

[0022] Furthermore, the locking spring 109 is disposed on the inner sidewall of the rotating head 105, and the locking spring 109 is in contact with the transmission shaft 106.

[0023] In this embodiment, the locking spring 109 can provide reverse pressure when the rotating head 105 is installed, to help the worker fix the rotating head 105.

[0024] Furthermore, the assembly plate 102 has a trapezoidal groove 112, which slides in conjunction with the trapezoidal block 111. The assembly plate 102 has a countersunk hole 113, which rotates in conjunction with the countersunk hexagonal bolt 110. The trapezoidal block 111 has a threaded hole 114, which threaded in conjunction with the countersunk hexagonal bolt 110.

[0025] In this embodiment, when installing the connecting housing 103, the countersunk hexagonal bolt 110 passes through the countersunk hole 113 and the trapezoidal groove 112 and is threadedly connected to the threaded hole 114 on the trapezoidal block 111. The trapezoidal block 111 can slide in the trapezoidal groove 112 to realize the axial rotation of the adjusting head, which facilitates the cutting tool to perform processing.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
