[0002] Tee or cross parts include but are not limited to pipe tees, crosses and other products. Generally, standard tee or cross parts are processed by dedicated highly automated processing machines, but for the processing of some small batches of non-standard workpieces such as tee or cross parts, such as the processing of threaded connections after the processing of non-standard workpiece blanks, since they are not suitable for standard special machine tools, if they are processed by machining centers, programming hours will be wasted, and the unit price of labor hours will be greatly increased, which seriously increases the processing cost.
[0003] In view of this, combined with the consideration of the processing technology of this type of workpiece, our company completes the processing work through ordinary lathes or general CNC lathes. However, when using lathes for processing, it is necessary to consider clamping the workpiece on the spindle to drive the workpiece to rotate at high speed. For this reason, we specially design clamping tooling for processing small batches of three-way or four-way parts, so that the processing of this type of workpiece can be completed by ordinary lathes or general CNC lathes.

[0022] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.
[0023] See also Figure 1-4The utility model discloses a fixture for machining three-way or four-way parts. The fixture for machining three-way or four-way parts is used to clamp a workpiece 500 when machining three-way or four-way parts, so that an irregular workpiece 500 can be set on the spindle of a lathe (ordinary lathe or digital lathe) to further complete the machining of the three-way or four-way parts.
[0024] Specifically, Figure 1 and Figure 2 The clamp for machining three-way or four-way parts includes a clamping body 100, a supporting block 200, a clamping mechanism 300 and a limiting block 400.
[0025] The clamping body 100 is cylindrical, and one end is provided with four mounting surfaces 101 evenly distributed around the circumference, and a circular limiting protrusion 102 is provided in the middle of the end surface of one end where the mounting surface 101 is provided.
[0026] The support block 200 is L-shaped, with one end fixedly connected to one of the mounting surfaces 101 , and the end surface of the other end extending toward the limiting protrusion 102 to form a support surface 201 .
[0027] Among them, the clamping mechanism 300 includes a mounting plate 301 fixedly connected to the mounting surface 101 on the opposite side of the support block 200, and a clamping block 302 that can slide toward or away from the support block 200 is arranged on the mounting plate 301, and a pushing mechanism 306 is arranged on the mounting plate 301 to push the clamping block 302 toward the support block 200.
[0028] Among them, the limit block 400 is L-shaped, and there are two of them. One end of the limit block 400 is detachably connected to the mounting surface 101 adjacent to the support block 200, and the other end extends toward the limit protrusion 102. A protruding structure 401 is provided in the middle of the end surface of the end extending toward the limit protrusion 102, and the end surfaces of the limit block 400 form limit platforms 402 on both sides of the protruding structure 401.
[0029] like Figure 3As shown, taking the clamping of a four-way part workpiece 500 as an example, when working, first remove the two limit blocks 400, and let the clamping block 302 of the clamping mechanism 300 be in a state away from the support block 200; then pick up the workpiece 500 and insert the opposite end of the end to be processed of the workpiece 500 on the limit protrusion 102, and use the limit protrusion 102 and the end face of the clamping body 100 to form support and limit for the opposite end of the end to be processed of the workpiece 500; at this time, one side of the workpiece 500 is against the supporting surface 201, and the two ends of the workpiece 500 adjacent to the end to be processed are set toward the two limit blocks 400. Then, we set the limit block 400, install the limit block 400 on the installation surface 101, insert the protruding structure 401 into the end of the workpiece 500, and make the limit table 402 support the end face of the workpiece 500, so as to further limit the workpiece 500; then use the pushing mechanism 306 to push the clamping block 302 toward the support block 200 to cooperate with the support surface 201 to clamp the workpiece 500; at this time, the clamping of the workpiece 500 is completed; after completing the clamping of the workpiece 500, the clamping body 100 is clamped on the spindle chuck of the lathe to start processing, such as processing such as Figure 3 The thread structure 501 is shown.
[0030] The protruding structures 401 extending into the two end portions adjacent to the end to be processed of the workpiece 500 can serve as a safety precaution during the processing to prevent the risk of the workpiece 500 being accidentally thrown off.
[0031] When it is necessary to disassemble the workpiece 500 or to change the processing part, the reverse operation can be performed.
[0032] In order to support the sliding requirements of the clamping block 302 , two parallel guide rods 303 are slidably provided on the upper part of the mounting plate 301 , and the ends of the two guide rods 303 close to one end of the supporting block 200 are connected to the clamping block 302 together.
[0033] At the same time, a large end portion 304 is provided at one end of the guide rod 303 away from the clamping block 302, and a spring 305 is sleeved on the guide rod 303, and the spring 305 is supported between the large end portion 304 and the mounting plate 301. In this way, when the pushing mechanism 306 does not act on the clamping block 302, the clamping block 302 can actively move away from the support block 200, thereby increasing the convenience of operation.
[0034] The pushing mechanism 306 includes a threaded hole 307 arranged on the mounting plate 301 opposite to the clamping block 302 , and a screw rod 308 is arranged on the threaded hole 307 . Rotating the screw rod 308 can make one end of the screw rod 308 push the clamping block 302 toward the support block 200 .
[0035] In order to solve the problem of detachable installation of the limit block 400, a first screw hole 103 is provided on the installation surface 101 of the limit block 400, and a first through hole 403 opposite to the first screw hole 103 is provided on the limit block 400. A first screw 404 is provided on the first through hole 403 and is threadedly connected with the first screw hole 103 after passing through the first through hole 403.
[0036] In order to solve the installation problem of the support block 200 and the mounting plate 301, second screw holes 104 are respectively provided on the mounting surfaces 101 of the support block 200 and the mounting plate 301, and second through holes 203 opposite to the second screw holes 104 are respectively provided on the support block 200 and the mounting plate 301, and each second through hole 203 is provided with a second screw 204 that passes through the second through hole 203 and is threadedly connected with the second screw hole 104.
[0037] Furthermore, two protrusions 202 are respectively arranged on both sides of the support surface 201 adjacent to the limit block 400, and the two protrusions 202 on each side are respectively arranged on both sides of the support block 200 in the thickness direction. Figure 3 and Figure 4 It can be seen that when the clamping block 302 cooperates with the supporting surface 201 of the supporting block 200 to clamp the workpiece 500, the protrusions 202 on both sides of the end of the workpiece 500 play a further limiting role on the side of the workpiece 500, thereby improving the reliability of clamping.
[0038] In addition, if Figure 4 As shown, the clamp for machining tee or cross parts can also be used for clamping tee parts 500. When clamping the tee parts 500, the end of the protruding structure 401 of one of the limit blocks 400 directly presses on the workpiece 500 to form a limit.
[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
