The inner part of the elbow pipe orifice is processed with internal threads, and the outer part of the pipe head is processed with external threads. When processing the internal threads of the elbow, however, the existing lathe processing is time-consuming due to clamping and tool adjustment, that is, it is difficult to effectively fix the position of the elbow, and it is impossible to position elbows with special structural shapes. It requires the tool adjuster to have excellent skills and highly relies on experience, which not only lacks reliability but also easily leads to low output and high production costs. Summary of the Invention

The output end of the driving cylinder is bolted to a guide rail, and a moving support corresponding to the fixed support and used for pressing the elbow is fixedly installed on the guide rail. The machine table is provided with a locking mechanism for clamping the elbow through the fixed support.

[0007] Preferably, the guide rail is slidably installed on the machine table through the driving cylinder.

[0008] Preferably, a first chamfer groove and a second chamfer groove for sleeving the elbow are respectively formed in the fixed support and the moving support.

[0009] Preferably, the locking mechanism includes a hollow cavity and a locking counterbore respectively formed in the fixed support. A telescopic support fixed by the locking counterbore is slidably sleeved in the hollow cavity. An extension support is integrally connected to the telescopic support.

Two limiting grooves are symmetrically formed in the extension support. A lifting slider movably pulled by the deflection swing rod is slidably sleeved in the limiting grooves. A clamping member for clamping one end of the elbow is integrally connected to the lifting slider.

[0010] Preferably, a locking screw for fixing the telescopic bracket is threadedly installed in the locking counterbore.

[0011] Preferably, a traction connecting rod is pin-connected between the end of the deflection swing rod and the lifting slider.

[0012] Preferably, the clamping member corresponds to the first chamfer groove and the second chamfer groove.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figures 1 - 4 A new type of elbow tapping tooling includes a machine table 1 mounted on a tapping machine, a first bracket 2 and a fixed support 3 for carrying the elbow are fixedly mounted on both ends of the machine table 1, and a driving cylinder 4 is fixedly mounted on the first bracket 2, and a guide rail 5 is bolted to the output end of the driving cylinder 4, and a movable support 6 corresponding to the fixed support 3 and used to press the elbow is fixedly mounted on the guide rail 5. For details, please refer to the attached manual Figure 1 By placing the elbow on the fixed support 3 and driving the movable support 6 toward one side of the fixed support 3, the elbow is clamped and fixed by using the fixed support 3 and the movable support 6 that are in abutment connection.

[0023] The machine 1 is provided with a locking mechanism for clamping the elbow through the fixed support 3, and the locking mechanism includes a hollow cavity 9 and a locking countersunk hole 10 respectively opened in the fixed support 3, and a telescopic bracket 11 fixed by the locking countersunk hole 10 is slidably sleeved in the hollow cavity 9, and an extension bracket 12 is integrally connected to the telescopic bracket 11. The telescopic bracket 11 and the extension bracket 12 can be horizontally adjusted according to the length of the end of the elbow extending outside the fixed support 3 and the movable support 6, so that the locking mechanism can stably operate the end of the elbow that needs to be tapped, and a driving bracket 12 is fixedly installed on the extension bracket 12. The driving motor 13 is provided, and a deflection rocker arm 14 is key-connected to the output end of the driving motor 13. Two limit slots 15 are symmetrically provided in the extension bracket 12. A lifting slider 16 movably pulled by the deflection rocker arm 14 is slidably sleeved in the limit slot 15. A clamping piece 18 for clamping one end of the elbow is integrally connected to the lifting slider 16. The driving action of the driving motor 13 causes the clamping piece 18 to move toward or in the opposite direction. A rubber pad is embedded in the arc-shaped clamping piece 18. The clamping piece 18 in the closed state forms a ring structure sleeved on the elbow to clamp and fix one end of the elbow.

[0024] The guide rail 5 is slidably installed on the machine platform 1 through the driving cylinder 4 to provide a guiding and supporting function for the horizontally moving support 6.

[0025] The fixed support 3 and the movable support 6 are respectively provided with a first chamfered groove 7 and a second chamfered groove 8 for fitting the elbow. It is worth noting that by combining the first chamfered groove 7 and the second chamfered groove 8, the elbow can be confined in a closed space, thereby achieving preliminary positioning of the elbow.

[0026] A locking screw for fixing the telescopic bracket 11 is threadedly installed in the locking counterbore 10 to lock and fix the telescopic bracket 11.

[0027] A pin shaft is connected between the end of the deflection swing rod 14 and the lifting slider 16, and a traction connecting rod 17 is provided. For details, please refer to the attached Figure 2 to the attached Figure 4 . By driving the deflection of the deflection swing rod 14, the lifting slider 16 is pulled through the traction connecting rod 17, so as to drive the clamping member 18 to close, and limit and fix one end of the elbow extending outside the fixed support 3 and the moving support 6.

[0028] For details, please refer to the attached Figure 1 to the attached , the clamping member 18 corresponds to the first chamfer groove 7 and the second chamfer groove 8, and the first chamfer groove 7 and the second chamfer groove 8 are right-angled structures.

[0029] It should be noted that the specific model specifications of the driving cylinder 4 and the driving motor 13 need to be selected according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0030] The functional principle of the present utility model can be described through the following operation mode:

[0031] Insert the elbow into the first chamfer groove 7 on the fixed support 3 and control the driving cylinder 4 to start;

[0032] The output end of the driving cylinder 4 drives the moving support 6 to move horizontally through the guide rail 5 until the second chamfer groove 8 fits with the elbow, and at the same time, the moving support 6 closely abuts against the fixed support 3;

[0033] Control the telescopic support 11 to horizontally expand and contract on the fixed support 3, and lock and fix the telescopic support 11 in the locking counterbore 10;

[0034] Control the driving motor 13 to start on the extension support 12, so that the deflection swing rod 14 deflects. The deflection swing rod 14 pulls the two lifting sliders 16 to move towards each other through the traction connecting rod 17, so that the two clamping members 18 clamp and fix one end of the elbow extending outside the fixed support 3 and the moving support 6 in the closed state.

[0035] Adopting the above-mentioned limiting method not only saves the product processing cost, but also shortens the processing time, improves the product processing output, and enables the enterprise to obtain more benefits.

[0036] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
