Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a device for high-precision grinding of end faces of small batches of gears. Background Technology

[0002] Conventional single-sided and double-sided grinding machines perform excellently in mass production. They are highly automated, suitable for long-term, continuous production operations, and their accuracy and efficiency are well guaranteed in a large number of repetitive processes.

[0003] For small-batch or single-piece production, these machine tools are not utilized well. The time cost of setting up and adjusting the machine tools is relatively high, which greatly increases the cost of each product. Moreover, since small-batch production often lacks the statistical process control and standardized processes found in large-scale production, it is more difficult to control the size of the processed parts and the processing accuracy cannot be guaranteed.

[0004] Therefore, conventional single-sided or double-sided grinding machines are only suitable for mass production. For single-piece or small-batch production, the performance utilization rate of the equipment cannot be effectively achieved, and the dimensional accuracy is unstable. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] This utility model relates to a preferred embodiment of a device for high-precision grinding end face processing of small batches of gears.

[0030] Please see Figures 1 to 8 The device for high-precision grinding of small batch gear end faces includes: a worktable and a gear fixture fixedly supported on the worktable.

[0031] The gear fixture includes a fixture base 1, a hollow rotary platform reducer 2, a transition plate 3, and a fixture body 4. The hollow rotary platform reducer 2 is supported on the fixture base 1. The power input end of the hollow rotary platform reducer 2 is connected to a servo motor 5. The power output end of the hollow rotary platform reducer 2 is rotatably equipped with the transition plate 3. The fixture body 4 for clamping the gear 6 to be processed is installed on the transition plate 3. The servo motor 5 drives the hollow rotary platform reducer 2 to drive the transition plate 3 to rotate.

[0032] Furthermore, the tooling base 1 includes a base plate 101 connected to the workbench 7, two side support plates 102 longitudinally symmetrically supported on the base plate 101, and a top support plate 103 connected to the two side support plates 102. The hollow rotary platform reducer 2 is installed on the top support plate 103. The tooling base 1 supports and fixes the hollow rotary platform reducer 2 to ensure sufficient stability during use.

[0033] More preferably, the base plate 101 is locked to the workbench 7 by hexagonal screws, the top support plate 103 and the side support plate 102 are locked by hexagonal screws, the hollow rotary platform reducer 2 is locked to the top support plate 103 by hexagonal screws, and the servo motor 5 is locked to the hollow rotary platform reducer 2 by hexagonal screws.

[0034] Furthermore, the base plate 101 is provided with a waterproof cover 8 that can cover the servo motor 5. The waterproof cover 8 is locked onto the base plate 101 by hexagonal screws to prevent water, dust or other contaminants from entering the servo motor 5 and to avoid damage to the servo motor 5.

[0035] The bottom of tooling body 4 is pressed into the guide rod on the guide block to achieve centering between the tooling body and the adapter plate.

[0036] In this utility model, a guide block 9 is also provided between the adapter plate 3 and the tooling body 4. The guide block 9 is installed on the adapter plate 3 by means of hexagon socket screws. The bottom center of the tooling body 4 is connected to the guide block 9 by a locking member, so that the tooling body 4 and the adapter plate 5 are centered and connected.

[0037] The design of guide block 9 enhances the stability of the tooling body. The centering connection effectively controls the relative movement between tooling body 4 and adapter plate 3, thereby improving the reliability of the entire tooling body during operation.

[0038] To ensure that the gear 6 being processed can rotate synchronously with the tooling body 4 and the adapter plate 3, this utility model provides a limiting pin 10 on the tooling body 4 that can rotate the gear. The limiting pin 10 forms an integral part with the tooling body 4 and the adapter plate 3. The adapter plate is driven to rotate by the servo motor 5, which drives the tooling body and the limiting pin on the adapter plate to rotate synchronously, thereby making the gear being processed rotate synchronously.

[0039] This invention achieves precise rotation and positioning of the gear being processed through the rapid response and precise control of the servo motor. The gear being processed rotates synchronously with the adapter plate, ensuring overall stability and reliability, and improving processing accuracy and efficiency.

[0040] Furthermore, the present invention also includes a grinding head 11, which is disposed above the gear tooling. The grinding head includes a grinding wheel 1101, a connecting spindle 1102, and a pull stud 1103. The grinding wheel 1101 is detachably connected to the spindle 1104 of the machining center. One end of the connecting spindle 1102 is inserted into the center hole of the grinding wheel 1101 and connected to the grinding wheel 1101 by a locking nut 1105. The other end of the connecting spindle 1102 is connected to the spindle 1104 by the pull stud 1103.

[0041] Using the above solution, when in use:

[0042] First, install the tooling base 1 on the worktable 7 of the machining center, and then install the servo motor 5, the hollow rotary platform reducer 2 and the adapter plate 3. At this time, the guide block 9 and the gear tooling are not installed. First, use a grinding wheel to grind the adapter plate until it is smooth, and ensure that the grinding end face of the grinding wheel is absolutely parallel to the workpiece surface.

[0043] Then, the guide block 9 is installed on the adapter plate 3, and the tooling body 4 is pressed onto the guide block 9 to ensure the centering installation between the tooling body 4 and the adapter plate 3;

[0044] Finally, the center hole of the gear 6 to be processed is fitted onto the central shaft of the tooling body 4, the grinding head 11 is started, and the grinding wheel 1101 begins to descend. When the grinding wheel 1101 contacts the end face of the gear 6 to be processed, the end face grinding officially begins. After the grinding is completed, the grinding wheel 1101 begins to rise and return to the initial position.

[0045] This utility model device is an auxiliary device added to a conventional vertical machining center. It can achieve single-piece and small-batch production, and the processed products have very high precision and stability. It can effectively solve problems such as machine adjustment, output and efficiency when different parts of the same process are produced and the equipment is under pressure. It is especially reliable in terms of safe production.

[0046] The beneficial effects of this utility model for high-precision grinding end face processing device for small batches of gears are:

[0047] It can respond quickly and control precisely, enabling accurate rotation and positioning of the gears being processed, thus improving processing accuracy and efficiency. It is suitable for high-precision grinding of end faces of different gears in single-piece and small-batch production.

[0048] The tooling has a simple structure, can be modified using existing equipment to reduce costs, and is easy to use. It only needs to be installed on the worktable of a vertical machining center. When the device is removed, the equipment is restored to a regular vertical machining center, achieving dual or even multiple uses in one machine.

[0049] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
