Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary support devices for workpiece processing, and specifically relates to a weight reduction device for workpiece processing. Background Technology

[0002] In the field of machining, especially when machining large or heavy workpieces, the weight of the workpiece often places a significant load on the fixture. Traditional fixture designs primarily ensure workpiece stability by enhancing the rigidity of the clamping mechanism or increasing the clamping force. However, this leads to the following problems: accelerated fixture wear, as excessive clamping pressure accelerates wear on the fixture contact surfaces, reducing fixture life and increasing maintenance costs; and increased risk of workpiece deformation, as heavy workpieces may experience minor deformations during clamping due to uneven local stress, affecting machining accuracy, especially for high-precision components (such as those in aerospace and energy equipment). Currently, some solutions use auxiliary supports (such as jacks and pads) to share the workpiece weight, but this method suffers from inconvenient adjustment and poor flexibility, affecting machining efficiency and failing to meet the demands of modern high-efficiency machining. Therefore, there is an urgent need for a weight-reducing device that can dynamically adjust the support force and automatically adapt to changes in workpiece weight to reduce the load on the fixture while ensuring workpiece stability and accuracy during machining.

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components. Example

[0028] like Figures 1-6 As shown, a weight reduction device for workpiece processing includes an inner support rod 1, an elastic element 2 disposed on the inner support rod 1, an outer support rod 3 sleeved on the inner support rod 1, and a support ball 4 disposed on the outer support rod 3; the elastic element 2 has an elastic force that causes the outer support rod 3 to slide up and down on the outer wall of the inner support rod 1.

[0029] In this embodiment, as a specific solution, the outer support rod 3 is provided with a partition 31 inside, the elastic element 2 is located below the partition 31, and the support ball 4 is located above the partition 31.

[0030] In this embodiment, as a specific solution, a bearing block 5 is provided on the outside of the supporting ball 4, and the bearing block 5 is disposed above the partition 31 of the outer support rod 3.

[0031] In this embodiment, as a more specific solution, the bearing block 5 can be removed from the outer support rod 3. When the support ball 4 wears out, the bearing block 5 can be removed and the support ball 4 replaced. Furthermore, by setting the bearing block 5, the force of the workpiece pressing on the support ball 4 is not directly transmitted to the outer support rod 3, but is buffered by the bearing block 5, thus providing a certain degree of protection for the outer support rod 3. In addition, bearing blocks 5 of various specifications can be set, with different specifications of bearing blocks 5 matching support balls 4 of different diameters, thereby making them suitable for workpieces of different specifications.

[0032] In this embodiment, as a specific solution, the partition 31 is provided with a through hole 32; the through hole 32 can be used as an operating hole to remove the support block 5 by means of a tool during assembly and disassembly, and can also be used as a heat dissipation channel for the support block 5 during processing, so that the heat generated by the friction between the workpiece and the support ball 4 can be dissipated through the through hole 32 after passing through the support block 5.

[0033] In this embodiment, as a specific solution, the top of the support block 5 is an arc-shaped structure.

[0034] In this embodiment, as a specific solution, the inner support rod 1 is provided with a receiving groove 11, and the elastic element 2 is disposed in the receiving groove 11; the receiving groove 11 plays a certain limiting role for the elastic element 2, and more specifically, the elastic element 2 moves within the space formed below the partition 31 between the receiving groove 11 and the outer support rod 3.

[0035] In this embodiment, as a specific solution, the outer wall of the receiving groove 11 is provided with a plurality of slots 12; this slot design can reduce weight on the one hand, and reduce the constraint on the movement of the elastic element 2 on the other hand, so as to ensure that the elastic element 2 can stretch and contract smoothly.

[0036] In this embodiment, as a specific solution, the inner support rod 1 is also provided with a limiting hole 13; a pin or other component can be installed at the limiting hole 13 to limit the range of motion of the outer support rod 3 and prevent the outer support rod 3 from being pressed down too much and damaging the workpiece processing base 6.

[0037] In this embodiment, as a specific solution, the bottom of the inner support rod 1 is provided with a mounting part 14, which is used to install the inner support rod 1 onto the workpiece processing base 6.

[0038] In this embodiment, as a specific solution, the inner support rod 1 is detachably mounted on the workpiece processing base 6 via the mounting part 14.

[0039] The working principle of this utility model is as follows:

[0040] During operation, the workpiece to be processed is positioned on the workpiece processing base 6 using other positioning tools, fixtures, etc. This utility model is used to hold the workpiece to be processed, thereby reducing the weight of the workpiece. The specific weight reduction principle is as follows: When the workpiece contacts the supporting ball 4, under the elastic force of the elastic element 2, the outer support rod 3 has a buffer space to slide up and down on the outer wall of the inner support rod 1, thereby reducing the weight of the workpiece. In addition, besides reducing the weight, this utility model also plays an auxiliary positioning role because the spherical contact helps the workpiece slide during workpiece positioning.

[0041] This utility model has the following beneficial effects:

[0042] 1. This utility model achieves weight reduction by supporting the ball bearings to contact the workpiece and by using the elastic force of the elastic element itself to adapt to the weight of the workpiece. This helps to accurately position the workpiece and is convenient and flexible to use, meeting the needs of modern high-efficiency processing.

[0043] 2. This utility model has a bearing block set on the outside of the supporting ball, which can be removed to replace the supporting ball as needed, making the replacement operation more convenient;

[0044] 3. The inner support rod of this utility model is also provided with a limiting hole, which can limit the movement range of the outer support rod to a certain extent and avoid damage to the workpiece processing base.

[0045] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations.
