Description

Technical Field

[0001] The invention belongs to the field of machine tool processing and relates to a modular tooling for a gear cutting machine spindle and a use method thereof. Background Art

[0002] As gear turning machine equipment, gear turning tools and processing technology become increasingly mature, gear turning machines have gradually replaced gear shaping machines and become the mainstream equipment for internal gear ring processing, and have entered the mass production stage. Standard gear turning machines are usually composed of multiple axes such as X-axis, Y-axis, Z-axis, A-axis, B-axis, and C-axis. Among them, the main axis B axis is the core functional axis of the gear turning machine. During the gear turning process, there is a relatively inclined angle with the center line of the C axis, that is, the axis intersection angle. This angle is the key to generating the cutting force of the gear turning.

[0003] In the process of producing machine tools, in order to ensure the accuracy and performance of the machine tools, a series of precise calibration and measurement work is required for the spindle (B axis), including but not limited to the concentric assembly calibration of the spindle axis and the C axis axis, the calibration of the spindle Z direction and the worktable plane, the measurement of the distance between the spindle end face and the A axis center, spindle greasing, and continuous towing of the spindle. However, the traditional spindle tooling is an integrated design, that is, the tooling is directly connected to the inner taper hole of the spindle by the taper shank, and then the other end of the taper shank is processed according to the required function. This design results in the need to use more than five types of tooling to complete all the above steps during the production process, which not only has a long processing cycle, but also serious material waste.

[0004] In view of the above problems, the industry urgently needs a new type of tooling for the spindle of a gear turning machine. The tooling must have a modular design and be able to meet more than four tooling functions at the same time, thereby simplifying the production process, shortening the processing cycle, reducing material consumption, and improving production efficiency. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a modular tooling for a gear cutting machine spindle and a method of using the same, so as to solve the problems existing in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions: a modular tooling for a gear turning machine spindle, comprising a taper shank head, and a concentric parallel calibration shaft and a distance measuring head detachably connected to the taper shank head; the taper shank head has a dynamic balance adjustment structure, a first taper surface is provided at the connection between the top of the taper shank head and the spindle, and a second taper surface is provided at the connection between the bottom and the concentric parallel calibration shaft or the distance measuring head; the concentric parallel calibration shaft, the distance measuring head and the taper shank head are connected by screws to form a modular combination structure. .

[0007] Optionally, the tooling has three combination states: the first is the use of the tapered shank head alone; the second is the use of the tapered shank head and a concentric parallel calibration shaft in combination; the third is the use of the tapered shank head and a distance measuring head in combination. The above three combination states can all be installed in the tapered hole of the gear turning machine spindle for operation.

[0008] Optionally, when the taper shank head is used alone, it is used for spindle greasing and continuous towing, and has the function of a dynamic balancing head; when the taper shank head is used in combination with a concentric parallel calibration axis, it is used for concentric assembly calibration of the B-axis centerline and the C-axis centerline and calibration of the spindle Z direction and the worktable plane; when the taper shank head is used in combination with a distance measuring head, it is used to measure the distance between the spindle end face and the A-axis center.

[0009] Optionally, a quick-change interface is designed between the concentric parallel calibration axis, the distance measuring head and the tapered handle head, and the quick-change interface is provided with four gourd holes arranged around the circumference.

[0010] Optionally, the gourd hole is a variable diameter hole, the large diameter end is a round hole and its size is larger than the maximum size of the screw, and the small diameter end is smaller than the maximum size of the screw but larger than the minimum size of the screw.

[0011] A method for using a modular tooling for a gear cutting machine spindle, using the modular tooling for a gear cutting machine spindle as described above, comprises the following steps:

[0012] S1, select the appropriate combination state according to the processing requirements, assemble the corresponding components and install them into the spindle taper hole of the gear cutting machine;

[0013] S2, start the machine tool and perform the required calibration, measurement or processing operations;

[0014] S3, when it is necessary to replace a part, by loosening the screws, rotating the part to be replaced, and then replacing it with the required part, there is no need to unscrew all the screws, so that quick replacement can be achieved, and subsequent operations can be continued after the replacement is completed.

[0015] Optionally, the taper shank head can be used alone during spindle greasing and continuous towing. The taper shank head and the concentric parallel calibration axis can be used in combination when performing concentric assembly calibration between the B-axis centerline and the C-axis centerline and calibration between the spindle Z direction and the worktable plane. The taper shank head and the distance measuring head can be used in combination when measuring the distance between the spindle end face and the A-axis center.

[0016] The beneficial effects of the present invention are:

[0017] 1) Improve production efficiency: Through modular design, this tooling can be flexibly combined into different functional states to meet various requirements such as spindle greasing, continuous towing, concentric assembly calibration of the spindle (B axis) axis centerline and the C axis axis centerline, calibration of the spindle Z direction and the worktable plane, and measurement of the distance between the spindle end face and the A axis center. This feature significantly reduces the time and labor costs required to replace tooling, thereby greatly improving production efficiency.

[0018] 2) Reduce costs: The modular design allows tooling components to be reused, avoiding the waste of materials caused by the single function of traditional one-piece tooling. At the same time, by reducing the types and quantity of tooling, the cost of inventory management and procurement is also reduced.

[0019] 3) Improve machining accuracy: Each tooling component is precision machined and strictly tested to ensure that it can maintain a high degree of accuracy and stability when used in combination. This helps to improve the overall machining accuracy of the gear turning machine and ensure product quality.

[0020] 4) Enhanced versatility and flexibility: The modular tooling of the present invention adopts a standardized design and is compatible with different types of gear turning machine spindles, which enhances its versatility. At the same time, users can quickly replace tooling components according to actual needs, realize flexible switching of functions, and meet diverse processing needs.

[0021] 5) Simplified operation process: Through the quick-change interface and simple disassembly and installation process, users can easily replace tooling components without complicated adjustment or calibration process, thus simplifying the operation process and reducing the difficulty of operation.

The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on the present invention. In order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of actual products. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0033] See also Figure 1 to Figure 5, which is a modular tooling for a gear turning machine spindle and a method of using the same, comprising a taper shank head 1, and a concentric parallel calibration shaft 4 and a distance measuring head 5 detachably connected to the taper shank head 1. The taper shank head 1 has a dynamic balance adjustment structure, which can provide stable dynamic balance during spindle grease and continuous towing. A first conical surface 11 is provided at the connection between the top of the taper shank head 1 and the spindle 2, which is used to fit tightly with the inner tapered hole of the spindle 2. A second conical surface 12 is provided at the bottom of the taper shank head 1, which is used to connect with the concentric parallel calibration shaft 4 or the distance measuring head 5.

[0034] The concentric parallel calibration shaft 4 and the distance measuring head 5 are connected to the cone handle head 1 by screws 3. This connection mode is not only firm and reliable, but also easy to disassemble and replace. Through the modular combination structure, the tooling can flexibly adapt to different processing requirements.

[0035] Specifically, the tooling has three combination states:

[0036] The first is that the taper handle head 1 is used alone. In this case, the tooling is mainly used for greasing and continuous towing operations of the spindle. The dynamic balancing adjustment structure of the taper handle head 1 can ensure the stability of the spindle during operation.

[0037] The second type is to use the tapered shank head 1 and the concentric parallel calibration axis 4 in combination. In this case, the tooling can realize the concentric assembly calibration of the spindle B axis centerline and the C axis centerline, as well as the calibration of the spindle Z direction and the worktable plane, to ensure the accuracy and performance of the machine tool;

[0038] The third type is the combined use of the taper shank head 1 and the distance measuring head 5. In this case, the tooling can measure the distance between the spindle end face and the center of the A-axis, providing accurate data support for subsequent processing operations.

[0039] In order to further improve the convenience of replacing parts, a quick-change interface 6 is also designed between the concentric parallel calibration shaft 4, the distance measuring head 5 and the cone handle head 1. The quick-change interface 6 is provided with four gourd holes 61 evenly distributed around the circumference. The gourd holes 61 are variable diameter holes. The large diameter end is a round hole and the size is larger than the maximum size of the screw 3, and the small diameter end is smaller than the maximum size of the screw 3 but larger than the minimum size of the screw 3. This design makes it easy to replace parts by simply loosening the screw 3 and rotating the part to be replaced, without having to unscrew all the screws 3, thereby greatly improving the replacement efficiency.

[0040] The present invention, when used, comprises the following steps:

[0041] S1, select the appropriate combination state according to the processing requirements, assemble the corresponding components and install them into the spindle taper hole of the gear cutting machine;

[0042] S2, start the machine tool and perform the required calibration, measurement or processing operations;

[0043] S3, when it is necessary to replace a part, by loosening the screws, rotating the part to be replaced, and then replacing it with the required part, there is no need to unscrew all the screws, so that quick replacement can be achieved, and subsequent operations can be continued after the replacement is completed.

[0044] Through the description of the above embodiments, it can be seen that the modular tooling for the spindle of the gear cutting machine and the method of using the same proposed by the present invention have significant beneficial effects, which not only improve production efficiency and reduce costs, but also improve processing accuracy and enhance universal flexibility. At the same time, the quick-change interface and the simple disassembly and installation process also further simplify the operation process and reduce the difficulty of operation.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
