Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining fixture technology, and in particular to a fixture for machining support plates. Background Technology
[0002] In the machining process, in order to ensure the machining accuracy and quality of the workpiece, a fixture is generally used to fix the workpiece on the worktable.
[0003] like Figure 1 The support plate workpiece a shown is an aluminum part made by casting. After the casting process is cooled and formed, the support plate workpiece a still needs to be turned, milled, drilled, polished and ground by equipment such as lathes, milling machines, drilling machines and grinding machines to correct the dimensional deviations and surface roughness of the casting process, improve the dimensional and shape accuracy of the support plate workpiece a, and realize the processing of complex structures such as grooves of the support plate workpiece a. During machining, the support plate workpiece a is clamped onto the worktable of the corresponding machine tool using a fixture. However, since the support plate workpiece a includes an L-shaped bracket part a1 and a connecting plate part a2, the structure of this type of workpiece is relatively complex. It is necessary to rotate and flip to adjust the clamping posture in order to achieve machining of different parts. However, some existing machining fixtures can only clamp the support plate workpiece a in a single posture and cannot meet the requirements of clamping the support plate workpiece a in multiple postures. Therefore, different machining fixtures need to be used for clamping when machining different parts. Disassembling and changing different machining fixtures on the machine tool worktable increases the operation time. Moreover, some existing machining fixtures can only clamp a single support plate workpiece a at a time and cannot clamp multiple support plate workpieces a at the same time, which reduces the machining efficiency.

[0021] like Figures 2-6As shown in the embodiment of this application, a fixture for processing a support plate includes a base 1, a backing plate 2, and a side plate 3. The top of the base 1 is provided with at least two sets of first positioning pins 4 and at least two sets of second positioning pins 5. The first positioning pins 4 are used to position the connecting plate portion a2 that is horizontally placed in the front-back direction, and the second positioning pins 5 are used to position the connecting plate portion a2 that is horizontally placed in the left-right direction. The top of the base 1 is also provided with at least two sets of horizontal positioning grooves 6, which are used to position the L-shaped support portion a1 that is horizontally placed in the front-back direction. The backing plate 2 is parallel to the top of the base 1 and the front end of the backing plate 2 is shorter than the base 1. At least three spaced positioning blocks 21 are fixedly connected to the front side of the backing plate 2. A vertical positioning groove 7 corresponding to the horizontal positioning groove 6 is formed between two adjacent positioning blocks 21. The vertical positioning groove 7 is used to position the vertically placed connecting plate portion a2. The side plate 3 is vertically fixedly connected between the rear side of the backing plate 2 and the rear side of the base 1.
[0022] Optionally, each group has at least three first positioning pins 4 and at least three second positioning pins 5.

The first positioning pins 4 are inserted into the first positioning pin holes 8 and the second positioning pins 5 are inserted into the second positioning pin holes 9. The first positioning pins 4 and the first positioning pin holes 8 are fitted with a small clearance, and the second positioning pins 5 and the second positioning pin holes 9 are fitted with a small clearance, which facilitates the insertion and removal of the first positioning pins 4 and the second positioning pins 5. The first positioning pins 4 or the second positioning pins 5 can be inserted for positioning according to the placement posture of the support plate workpiece a.
[0023] Specifically, the top of the base 1 is also provided with a vertical positioning through hole 10 located behind the horizontal positioning groove 6. The vertical positioning through hole 10 is used to position the vertical plate of the L-shaped support part a1 that is placed horizontally in the front-back direction. That is, when the L-shaped support part a1 of the support plate workpiece a is in a horizontal position and the vertical plate of the L-shaped support part a1 faces the rear of the base 1, the vertical plate of the L-shaped support part a1 can be inserted into the vertical positioning through hole 10, and the horizontal plate of the L-shaped support part a1 is placed in the horizontal positioning groove 6, thereby realizing the positioning of the L-shaped support part a1.
[0024] A support block 22 is fixedly connected to the top of the support plate 2 above the vertical positioning groove 7. The support block 22 matches the top of the connecting plate a2. When the connecting plate a2 is in a vertical position, the connecting plate a2 is placed in the vertical positioning groove 7, and the top of the connecting plate a2 can abut against the support block 22.
[0025] The bottom of the horizontal positioning groove 6 is provided with an upwardly protruding positioning protrusion 61. The positioning protrusion 61 matches the groove structure a11 on the L-shaped bracket a1. When the horizontal plate of the L-shaped bracket a1 is placed in the horizontal positioning groove 6, the positioning protrusion 61 can be inserted into the groove structure a11 to further realize the positioning of the L-shaped bracket a1.
[0026] The method of using this fixture is as follows:
[0027] The fixture is installed on the machine tool's worktable. This fixture can clamp the support plate workpiece a in various postures: When the connecting plate part a2 of the support plate workpiece a is processed in a horizontal posture in the front-to-back direction, the connecting plate part a2 is positioned and fixed by the first positioning pin 4. At this time, the L-shaped bracket part a1 is vertically suspended on the front side of the base 1; When the connecting plate part a2 of the support plate workpiece a is processed in a horizontal posture in the left-to-right direction, the connecting plate part a2 is positioned and fixed by the second positioning pin 5. At this time, the L-shaped bracket part a1 is vertically suspended on the left or right side of the base 1; When the connecting plate part a2 of the support plate workpiece a is processed in a vertical posture, the connecting plate part a2 is positioned and fixed by the vertical positioning groove 7. At this time, the L-shaped bracket part a1 is in a horizontal posture. The horizontal positioning groove 6 fixes and limits the L-shaped bracket part a1. The vertical plate of the L-shaped bracket part a1 can be suspended on the front side of the base 1, or the vertical plate of the L-shaped bracket part a1 can be inserted into the vertical positioning through hole 10 for positioning. The fixture uses a structure consisting of a first positioning pin 4, a second positioning pin 5, a horizontal positioning groove 6, and a vertical positioning groove 7 to position and fix the support plate workpiece a, which can prevent incorrect installation and makes the clamping operation simple and quick, thus improving processing efficiency. In addition, since there are at least two sets of the first positioning pin 4, the second positioning pin 5, the horizontal positioning groove 6, and the vertical positioning groove 7, the fixture can clamp multiple support plate workpieces a at once, thereby improving processing efficiency and increasing output.
[0028] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
