Description

Technical Field

[0001] The utility model relates to the technical field of positioning fixtures, in particular to a five-axis grinding machine fixture. Background Art

[0002] In modern manufacturing, the requirements for component machining precision are becoming increasingly stringent. For example, in the aerospace sector, components such as engine blades and aircraft structures require extremely high dimensional accuracy and surface quality. Five-axis grinding machines, as high-precision machining equipment, play an important role in meeting these demands.

[0003] The automotive manufacturing industry also has a continuously growing demand for precision parts, such as key components of automobile engines and high-precision transmission parts. The manufacturing accuracy of these parts directly affects the performance, reliability and fuel efficiency of the car.

[0004] Traditional grinding machine fixtures are often only able to adapt to simple machining shapes and limited machining directions. For some complex-shaped workpieces, such as parts with irregular surfaces, traditional fixtures have difficulty ensuring accurate machining positioning in multiple directions.

[0005] Traditional fixtures also have stability issues during five-axis grinding. Because five-axis grinding involves the linkage of multiple coordinate axes, traditional fixtures may experience slight displacement or vibration during processing, thus affecting processing accuracy.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example

[0025] like Figure 1-4As shown, a five-axis grinding machine fixture proposed in one embodiment of the present invention includes a base body 1, a slider groove 2 is integrally cast on the upper end surface of the base body 1, a T-shaped bevel groove 3 is provided on the base body 1, a positioning surface 1 4 is formed on the bottom end surface of the base body 1, and air escape grooves 5 are staggeredly distributed in the positioning surface 1 4, a positioning surface 2 6 is integrally cast on the front end surface of the base body 1, and a sliding wall 7 is formed on the bottom of the base body 1;

[0026] Base body 1

[0027] This is the core part of the fixture, providing the basic structural framework for the entire fixture. All other structural components are built based on the base body 1 or are associated with the base body 1.

[0028] Slider slot 2

[0029] The slider groove 2 is located on the upper end surface of the base body 1 and is formed by integral casting. The slider groove 2 plays the role of guiding the slider movement or accommodating the slider in the fixture.

[0030] T-type chute 3

[0031] The inclined surface of the base body 1 is inclined. This inclined T-shaped bevel slot 3 may be used to cooperate with other components with T-shaped structures, and can be used to install positioning blocks or clamping devices of specific shapes. The inclined design is related to the special processing angles or motion trajectories of the five-axis grinder.

[0032] Positioning surface 4

[0033] It is formed on the bottom end surface of the base body 1. The positioning surface 1 4 is an important surface for contact and positioning of the fixture with the workbench when the fixture is installed on the grinder workbench, and plays a key role in ensuring the accurate position of the fixture on the grinder.

[0034] Avoidance slot 5

[0035] Staggered distribution in the positioning surface 4. The existence of the avoidance groove 5 is mainly to avoid interference between certain components and the bottom surface of the fixture during the processing, so as to ensure the smooth progress of the processing.

[0036] Positioning surface 26

[0037] It is integrally cast on the front end of the base body 1. It is another surface for positioning, and together with the positioning surface 14, it accurately defines the position of the fixture from different directions, which helps to improve the positioning accuracy of the fixture in multiple dimensions.

[0038] Sliding wall 7

[0039] Located at the bottom of the base body 1. The sliding wall 7 may be to enable the fixture to slide on a specific guide rail or support structure, thereby facilitating the adjustment of the position of the fixture on the grinding machine, or cooperating with certain movable parts of the grinding machine.

[0040] This fixture is primarily used for centering five-axis grinders. It is positioned on the grinder via its locating surface and secured to the grinder via a T-shaped bevel slot 3. Screws secured via the T-shaped co-slot ensure that both locating surface 1 (4) and locating surface 2 (6) are in full contact with the grinder, guaranteeing precise positioning. A clearance groove 5 is designed on locating surface 1 (4) to prevent the formation of an oil film between the fixture and the grinder's worktable, which could cause the fixture to be sucked onto the grinder's worktable. The sliding wall 7 and sliding slot are precision-machined to ensure the accuracy of the positioning accessory during sliding.

[0041] like Figure 2 As shown, in some embodiments, both sides of the slider slot 2 need to be higher than the plane of the base body 1; this height difference can also accurately limit the lateral movement range of the slider. In some processing scenarios that require high-precision positioning, the movement range of the slider must be strictly controlled.

[0042] like Figure 3 As shown, in some embodiments, the positioning surface 1 4 and the air-avoiding groove 5 are provided on the sliding wall 7; providing the positioning surface 1 4 and the air-avoiding groove 5 on the sliding wall 7 is a way to optimize the use of space.

[0043] like Figure 3 As shown, in some embodiments, the T-shaped bevel slot 3 is arranged with an inclined surface on the base body 1. During the machining process of a five-axis grinder, the fixture is subjected to various forces, such as cutting force and clamping force. The T-shaped bevel slot 3 is arranged with an inclined surface on the base body 1. This structure can effectively decompose and transmit the forces acting on the fixture.

[0044] In some embodiments, the base body 1 is made of a high-strength aluminum alloy. During the five-axis grinding process, a certain amount of heat is generated, especially near the cutting area. High-strength aluminum alloy has excellent thermal conductivity, which can quickly transfer the heat generated during the machining process. This helps prevent deformation of the fixture due to local overheating or affect its mechanical properties. Good thermal conductivity also helps maintain the temperature stability of the machining environment, which plays a certain auxiliary role in improving machining accuracy.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
