Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, specifically to a tooling and fixture for machining. Background Technology
[0002] Machining, or machining, is a key process that uses specialized equipment to precisely cut and remove material to shape parts, transforming raw materials into mechanical components that meet various requirements. During machining, the processing equipment exerts significant forces on the workpiece, causing it to shift and introduce considerable errors. Specialized tooling fixtures are typically used to position the workpiece. However, the dimensions of machining equipment and the size of the processing area vary. In environments with limited space, the size and range of motion of the fixtures are restricted, affecting the accuracy of workpiece clamping and leading to quality issues. Therefore, this paper presents a tooling fixture for machining. Utility Model Content
[0003] The purpose of this utility model is to provide a tooling fixture for machining to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for machining, comprising a base, two sets of movable stages at the top of the base, and two sets of grippers at the top of the movable stages. A fixed shaft passes through the interior of each of the two sets of grippers and is installed inside a movable groove. A connecting hole is provided at the bottom of each of the two sets of grippers, and the connecting hole forms a movable connection with a push rod. A push plate is installed at the end of the push rod, and a spring is installed at the top of the push plate located outside the push rod. A cylinder is installed at the bottom of the movable stages, and a top block is installed at the top of the cylinder.
[0005] Preferably, the base has a reserved groove inside, and the size of the reserved groove is larger than the size of the cylinder.
[0006] Preferably, the two sets of grippers are symmetrically distributed at the top of the moving platform, and the two sets of push rods are distributed in a "V" shape inside the moving platform.
[0007] Preferably, a slide rail assembly is provided between the top end of the base and the bottom end of the moving platform, and the slider in the slide rail assembly is fixedly connected to the moving platform. Two sets of slide rail assemblies are provided, and the slide rail assemblies are symmetrically distributed on the base.
[0008] Preferably, a positioning plate is installed on the outer side of the mobile platform, and the positioning plate and the mobile platform are welded together as an integral structure.
[0009] Preferably, a positioning bolt is installed at the bottom end of the positioning plate, and a threaded connection is formed between the positioning bolt and the positioning plate. The positioning bolt passes through the interior of the positioning plate and contacts the outer wall of the base.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] (1) By setting up a moving table, grippers, cylinder, top block, fixed shaft, push rod, connecting hole, push plate and spring, the workpiece is accurately clamped. The operation of the cylinder will push the top block to move upward and push the push plate to move to the side, and compress the spring, which will push the two sets of grippers to rotate around the fixed shaft as the axis, accurately clamping both sides of the workpiece. The fixture has a small range of motion, which is convenient for accurately and quickly clamping and positioning the workpiece in a space-limited environment, thus improving the processing quality of the workpiece.
[0012] (2) By setting a base, positioning plate, moving table, slide rail assembly and positioning bolt, the size of the fixture can be adjusted. The two moving tables are installed between the base and the base, which makes it easy for the two moving tables to move horizontally on the top of the base and adjust the position and distance of the two moving tables to adapt to workpieces of different lengths. At the same time, the rotation of the positioning bolt can press against the outer wall of the base, increase friction, lock the position of the moving table, and thus improve the flexibility of use.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] Please see Figure 1-4 This utility model provides an embodiment of a tooling fixture for machining, comprising a base 1, two sets of movable tables 3 at the top of the base 1, and two sets of grippers 4 at the top of the movable tables 3. A fixed shaft 11 passes through the interior of the two sets of grippers 4 and is installed inside the movable groove 9. A connecting hole 13 is provided at the bottom of each set of grippers 4, and the connecting hole 13 is movably connected to a push rod 12. A push plate 14 is installed at the end of the push rod 12, and a spring 15 is installed at the top of the push plate 14 at the outer position of the push rod 12. A cylinder 8 is installed at the bottom of the movable table 3, and a top block 10 is installed at the top of the cylinder 8. A reserved groove 7 is provided inside the base 1, and the size of the reserved groove 7 is larger than the size of the cylinder 8. The two sets of grippers 4 are symmetrically distributed at the top of the movable table 3, and the two sets of push rods 12 are distributed in a "V" shape inside the movable table 3.
[0023] Specifically, as shown in the figure, during use, the operation of the cylinder 8 will push the top block 10 to move upward and push the push plate 14 to move to the side, and compress the spring 15, which will push the two sets of grippers 4 to rotate around the fixed shaft 11 as the axis, so as to accurately clamp the two sides of the workpiece.
[0024] A slide rail assembly 5 is provided between the top end of the base 1 and the bottom end of the moving platform 3, and the slider in the slide rail assembly 5 is fixedly connected to the moving platform 3. Two sets of slide rail assemblies 5 are provided and are symmetrically distributed on the base 1. A positioning plate 2 is installed on the outside of the moving platform 3, and the positioning plate 2 and the moving platform 3 are welded together. A positioning bolt 6 is installed at the bottom end of the positioning plate 2, and the positioning bolt 6 is threadedly connected to the positioning plate 2. The positioning bolt 6 passes through the interior of the positioning plate 2 and contacts the outer wall of the base 1.
[0025] Specifically, as shown in the figure, during use, a slide rail assembly 5 is installed between the two sets of moving platforms 3 and the base 1, which facilitates the translation of the two sets of moving platforms 3 on the top of the base 1, and adjusts the position and distance of the two sets of moving platforms 3 to accommodate workpieces of different lengths.
[0026] Working principle: In use, first, the fixture is taken out, moved to the target area, and fixed with fasteners. The positioning bolt 6 is rotated outward to move it away from the outer wall of the base 1, pushing the moving table 3 to slide along the direction of the slide rail assembly 5. The two moving tables 3 are moved to the appropriate position, and the positioning bolt 6 is rotated in the opposite direction to lock the position of the moving table 3 against the outer wall of the base 1, preventing the moving table 3 from shifting. Then, the two sets of cylinders 8 are electrically connected to the control device using wires to control the operation of the cylinders 8. When the cylinder 8 extends upward, it pushes the top block 10 upward and pushes the push plate 14 to move to the side, compressing the spring 15 and pushing the two sets of grippers 4 to rotate around the fixed shaft 11, accurately clamping the workpiece on both sides. When the cylinder 8 retracts, the push plate 14 is not pushed from below but is pushed by the spring 15, pulling the grippers 4 to flip outward, releasing the clamping state, and finally completing the use of the fixture.
[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
