Description

Technical Field

[0001] The present application relates to the technical field of processing tooling, and specifically to a parts processing tooling fixture. Background Art

[0002] Parts are the basic elements of a machine. A machine generally consists of one or more prime movers that receive external energy; an executive part that performs the machine's production functions, transmitting the prime mover's motion and power to the executive part; and a detection and control system that ensures the coordinated operation of all parts in the machine. Further decomposition of the machine reveals various parts.

[0003] Parts are used in machinery manufacturing, electronics industry, aerospace, automobile industry, medical equipment and other fields. For example, when machining aviation parts, machining tooling is required to reliably position and clamp them to prevent displacement and shaking during the machining process.

[0004] For example, the patent with publication number CN219837683U specifically discloses a fixed tooling for processing long-axis parts, including a base, two screws, a positioning plate, a nut, a positioning pad and an elastic clamping strip, so that the nut is adjusted to slide the positioning pad downward and make close contact with the outer wall of the part, while squeezing the outer wall of the part and the outer wall of the elastic clamping strip into close contact until the outer wall of the elastic clamping strip is fully in contact with the part, so that the positioning pad and the elastic clamping strip cooperate to fix the long-axis part between them.

[0005] The above patent fixes the parts by adjusting two sets of nuts to slide the positioning pad downward and bring the parts into close contact with the outer wall of the elastic clamp when clamping aviation parts. In this way, when processing shaft parts of different diameters, a knob operation must be performed each time the parts are fixed and released. The overall fixing operation is relatively cumbersome, which reduces the efficiency of part processing. Therefore, it is necessary to design a part processing fixture to solve the above problems.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0009] Furthermore, an elastic pad is provided at the contact position between the clamp and the pressure rod.

[0010] Furthermore, an open side groove adapted to the diameter of the rotating shaft is formed at one end of the pressure rod, and an anti-slip pad is provided at the contact position between the rotating shaft and the open side groove.

[0024] like Figure 1-Figure 3 As shown, the present application provides a parts processing fixture, which is used for processing aviation parts, including a base 1, on which support legs 101 are fixedly mounted, and the support legs 101 are used to provide auxiliary support for the base 1, and a workbench 103 is fixedly mounted on the base 1;

[0025] A fixing assembly 2 is mounted on the base 1. The fixing assembly 2 includes two sets of screw rods 201 fixedly mounted on the base 1. A fixing foot 202 is fixedly mounted on one end of the screw rods 201 close to the base 1. The screw rods 201 are fixedly mounted on the base 1 through the fixing foot 202.

[0026] A sliding post 203 is threadedly connected to the screw rod 201. The sliding post 203 includes two sets of annular grooves 212. A screw groove adapted to the screw rod 201 is opened on the sliding post 203. The sliding post 203 is adapted to rotate along the linear direction of the screw rod 201. A pressure rod 208 is movably sleeved on the two sets of screw rods 201. A sleeve hole 210 adapted to the diameter of the screw rod 201 is opened on the pressure rod 208.

[0027] A locking unit is mounted on the sliding column 203. The locking unit includes a movable ring 204 that is movably sleeved on a set of circular grooves 212. Two sets of side protrusions 205 are fixedly mounted on the movable ring 204. A connecting rod 206 is connected between the two sets of side protrusions 205. A rotating shaft 207 is movably sleeved on the connecting rod 206.

[0028] An open side groove 209 is formed at one end of the pressure rod 208, which is adapted to the diameter of the rotating shaft 207. The rotating shaft 207 is adapted to rotate along the rod core of the connecting rod 206 so as to be engaged in the open side groove 209. A clamp 211 is fixedly mounted at one end of the rotating shaft 207. The clamp 211 is adapted to be engaged in the open side groove 209 along with the rotating shaft 207, thereby being adapted to fit on the pressure rod 208 and further adapted to fix the pressure rod 208 on the sliding column 203.

[0029] In the present application, an elastic pad is provided at the contact position between the clamp 211 and the pressure rod 208 so as to fit the clamp 211 tightly onto the pressure rod 208;

[0030] In the present application, an anti-slip pad is provided at the contact position between the rotating shaft 207 and the open side groove 209 to prevent the rotating shaft 207 from falling out of the open side groove 209;

[0031] A clamping assembly 3 is mounted on the pressure rod 208. The clamping assembly 3 includes an upper clamping block 301 mounted on the pressure rod 208 near the workbench 103. The upper clamping block 301 has a fixed sleeve, which is connected to the pressure rod 208 through the fixed sleeve. A lower clamping block 302 is fixedly mounted on the workbench 103.
