Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of three-way clamps, and particularly relates to a lathe clamp for a special-shaped three-way pipe joint. Background Art
[0002] Pipe joints are widely used in hydraulic systems, and are divided into two-way, three-way, four-way, five-way and corresponding special-shaped pipe joints, etc. Usually, the pipe joints are distributed at 90°, with simple processing and convenient positioning. However, the angle between the two ends of the special-shaped pipe joint is not 90°, and the usual clamping method can no longer meet the requirements, and the processing has a certain degree of difficulty.
[0003] The branch ends of the special-shaped three-way pipe joint are all of a rotary body structure, and the processing features are basically all turning features. Usually, the turning clamp is a three-jaw or four-jaw one, which cannot firmly clamp the special-shaped three-way, resulting in a reduction in the processing efficiency of the special-shaped three-way pipe joint. Content of the Utility Model
[0004] In view of this, the lathe clamp for the special-shaped three-way pipe joint provided by the utility model solves the technical problem that the three-jaw or four-jaw cannot firmly clamp the special-shaped three-way, resulting in a reduction in the processing efficiency of the special-shaped three-way.
[0005] A lathe clamp for a special-shaped three-way pipe joint is suitable for processing a special-shaped three-way on a numerical control machine tool. The numerical control machine tool includes a processing table, and comprises a base body and a clamping assembly arranged on the base body. The base body is installed on the processing table. Among them,
[0006] After the special-shaped three-way is placed on the base body and aligned, it is firmly clamped by the clamping assembly to realize the rapid processing of the special-shaped three-way by the numerical control machine tool.
[0007] Preferably, a ring ear is arranged at a preset position on the main end or branch end of the special-shaped three-way.
[0008] Preferably, the base body is arranged in an L-shaped structure, and a first groove is opened at the edge position of one end, and a first hole is opened at a position adjacent to the first groove. The first groove is used for placing part of the clamping assembly.
[0009] Preferably, the clamping assembly includes a pressing plate, a fixing plate and a support block. The shape of the support block is adapted to the shape of the first groove, and a protrusion is arranged on the top surface; a second groove is opened at one end of the pressing plate, and the shape of the second groove is adapted to the shape of the protrusion and can socket part or all of the protrusion; a second hole is opened at a position corresponding to the first hole on the pressing plate; third holes are respectively opened at positions on both sides of the first groove on the base body, and fourth holes are opened at positions corresponding to the third holes on the fixing plate for fixing the support block to the base body. Among them,
[0010] One end of the special-shaped tee with a ring ear is sleeved on the protrusion and aligned. When the main end of the special-shaped tee is sleeved in the second groove, the ring ear is pressed down by the pressing plate, and the special-shaped tee is fixedly clamped by screwing a screw through the first hole and partially embedding it into the second hole. In addition, the fastener sequentially passes through the fourth hole and the third hole to fix the fixing plate to the support block installed in the first groove.
[0011] Advantageous effects
[0012] After the special-shaped tee is aligned, this clamping method does not require realignment again, solving the problem of difficult clamping of the special-shaped tee pipe joint. At the same time, the situation of misalignment of the special-shaped tee is avoided, ensuring the machining quality and efficiency of the parts. Description of the drawings

[0024] As Figures 1 to 4 shown, the lathe fixture for the special-shaped three-way pipe joint is applicable to the processing of special-shaped three-ways on a numerically controlled machine tool. The numerically controlled machine tool includes a processing table, which includes a base 2 and a clamping assembly provided on the base 2. The base 2 is installed on the processing table. Among them, after the special-shaped three-way is placed on the base 2 and aligned, it is firmly clamped by the clamping assembly to achieve the rapid processing of the special-shaped three-way by the numerically controlled machine tool. This structure can quickly align the special-shaped three-way to ensure that the axis of the three-way is concentric or coaxial with the processing axis of the numerically controlled machine tool.
[0025] As a specific embodiment provided in this case, a ring ear 1 is provided at a preset position on the main end of the special-shaped tee. The ring ears 1 can be continuously arranged or discontinuously arranged. When discontinuously arranged, it is at least greater than one-half of the circumferential area of the main end. The preset position is at one-third to one-half of the height of the main end. The special-shaped tee is processed by milling from a steel forging. For example, the angle between the two branch ends of the special-shaped tee is greater than 90°.
[0026] As a specific embodiment provided in this case, the base body 2 is arranged in an L-shaped structure, and a first groove 21 is opened at the edge position of one end, and a first hole 22 is opened near the first groove 21. The first groove 21 is used to place part of the clamping assembly, and the first hole 22 is used for fastening the clamping assembly. For example, screws are used for fastening.
[0027] Further, the clamping assembly includes a pressing plate 31, a fixing plate 32 and a support block 33. Preferably, the pressing plate 31 is arranged in an L-shaped structure. Specifically,
[0028] The shape of the support block 33 is adapted to the shape of the first groove 21, and a protrusion 4 is provided on the top surface. Preferably, the protrusion 4 is a cylinder and is integrally structured with the support block 33;
[0029] A second groove 311 is opened at one end of the pressing plate 31. The shape of the second groove 311 is adapted to the circumferential dimension of the main end of the special-shaped tee to realize the pressing down of the ring ear 1 by the pressing plate 31. A second hole 312 is opened at the position corresponding to the first hole 22 on the pressing plate 31, and third holes 23 are respectively opened at the positions on both sides of the first groove 21 on the base body 2. Fourth holes 321 are opened at the positions corresponding to the third holes 23 on the fixing plate 32 for fixing the support block 33 and the base body 2.
[0030] The operation method or principle of the component for firmly clamping the tee is as follows:
[0031] One end of the special-shaped tee with the ring ear 1 is sleeved on the protrusion 4 and aligned. For example, the tee is rotated on the protrusion 4;
[0032] After alignment, the second groove 311 is sleeved on the main end of the special-shaped tee (sleeved above the ring ear 1), so that the pressing plate 31 can press down the ring ear 1, and the special-shaped tee is fixedly clamped by screws passing through the first hole 22 and partially embedded in the second hole 312;
[0033] Fasteners (such as screws or pins) sequentially pass through the fourth holes 321 and the third holes 23 to fixedly connect the fixing plate 32 and the base body 2, so as to fix the support block 33 installed in the first groove 21, and prevent the support block 33 from shaking or moving during the processing of the tee, thereby affecting the processing quality of the tee.
[0034] As a specific implementation mode provided in this case, the second groove 311 is an arc groove, nesting at least more than one-half of the outer circumference of the main end of the three-way joint, and the first hole 22, the second hole 312, the third hole 23 and the fourth hole 321 are all threaded holes.
[0035] Overall, after alignment, subsequent part clamping does not require re-alignment, solving the problem of difficult clamping of special-shaped three-way pipe joints and avoiding the situation of aligning each part, greatly ensuring the machining quality and efficiency of the parts.
[0036] The above is only a specific implementation mode of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present disclosure should be covered by the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
