[0002] The ejector pipe is a common gas equipment part. The ejector pipe includes an ejector pipe body, a first connecting plate connected to the top of the ejector pipe body, and a second connecting plate connected to the bottom of the ejector pipe body. The ejector pipe body has a first mounting hole, and the first connecting plate has a second mounting hole. During production and manufacturing, accurate drilling and tapping operations are required. In order to ensure the machining precision and efficiency, a specially designed drilling and tapping jig is usually used to fix the ejector pipe.

[0003] The drilling and tapping jig for the ejector pipe mainly includes a rack, a mounting base mounted on the rack for arranging the ejector pipe, a clamping block for pressing the ejector pipe to the mounting base, and a clamping driving member for driving the clamping block to act. The mounting base is fixed on the rack so that the above-mentioned drilling and tapping jig for the ejector pipe can only adapt to the clamping and fixing of one type of ejector pipe.

[0004] For the related technology in the above, the inventors believe that a drilling and tapping jig capable of adapting to multiple types of ejector pipes is needed. CONTENT OF THE UTILITY MODEL

[0005] In order to enable the drilling and tapping jig for the ejector pipe to adapt to the clamping of multiple types of ejector pipes, the present application provides a drilling and tapping jig for an ejector pipe.

[0006] The drilling and tapping jig for the ejector pipe provided by the present application adopts the following technical scheme:

[0007] A drilling and tapping jig for an ejector pipe, comprising a rack, a mounting plate rotatably mounted on the top surface of the rack, a turnover mechanism for driving the mounting plate to horizontally turn over, and a clamping mechanism mounted on the mounting plate and used for clamping the ejector pipe; the clamping mechanism comprises a mounting base used for arranging the ejector pipe and detachably mounted on the mounting plate, a clamping block used for pressing the ejector pipe to the mounting base, and a clamping driving assembly for driving the clamping block to act; the mounting plate has a plug-in protruding column extending towards the mounting base, the mounting base has a plug-in groove for the plug-in protruding column, the outer side wall of the plug-in protruding column is horizontally provided with a mounting groove, and the mounting groove is provided with an elastic locking member, and the inner wall of the plug-in groove is provided with a locking groove matched with the elastic locking member.

[0008] By adopting the above technical solution, in the processing of the ejector tube, the ejector tube is first placed in the mounting base. The clamping drive assembly drives the clamping block to press the ejector tube firmly into the mounting base, thereby machining the first mounting hole on the ejector tube. Then, the mounting plate is flipped by the flipping mechanism to machine the second mounting hole on the ejector tube. The engagement between the elastic locking element and the locking groove enables a detachable connection between the mounting base and the mounting plate. A suitable mounting base can be replaced according to different ejector tube models, thus enabling the clamping of different ejector tube models. This allows the ejector tube drilling and tapping jig to adapt to the clamping of various ejector tube models.

[0009] Optionally, the elastic locking member includes a locking housing disposed in the mounting groove, a locking block slidably mounted on the locking housing, and a locking spring mounted on the locking housing. The locking block has a limiting protrusion and a locking protrusion for engaging with the locking groove. The locking housing has a locking opening for the locking protrusion to extend out and for limiting the limiting protrusion. One end of the locking spring abuts against the limiting protrusion and the other end abuts against the bottom surface of the inner cavity of the locking housing. The locking spring causes the locking protrusion to always have a tendency to disengage from the locking housing.

[0010] By adopting the above technical solution, the specific structure of the elastic locking component is disclosed. The locking spring ensures that the locking protrusion of the locking block always has a probability of disengaging from the locking housing, enabling automatic locking between the mounting base and the mounting plate when the locking protrusion slides into the locking groove. The locking opening helps to prevent the limiting disc from protruding from the locking housing.

[0011] Optionally, the locking groove is a through groove extending to the outer wall of the mounting base; the locking groove is provided with an unlocking mechanism for unlocking the elastic locking member; the locking groove has a first groove and a second groove connected to the side of the first groove away from the elastic locking member, the diameter of the first groove is larger than the diameter of the second groove; the unlocking mechanism includes an unlocking member slidably arranged in the locking groove, an unlocking spring sleeved on the unlocking member, and an unlocking nut installed on the unlocking member; the unlocking member includes an unlocking disc slidably arranged in the first groove and an unlocking rod connected to the unlocking disc and extending to the outside of the mounting base; one end of the unlocking spring abuts against the unlocking nut and the other end abuts against the mounting base.

[0012] By adopting the technical scheme, the specific structure of the unlocking structure is disclosed, when the elastic locking assembly needs to be unlocked, the operator pushes the unlocking rod to slide towards the direction of the plug-in convex column, so that the locking disc abuts against the end face of the plug-in convex column, so that the locking part of the locking convex column is out of the locking groove, thereby realizing the quick separation of the mounting base and the mounting plate, which is helpful for clamping different types of ejector tubes. The setting of the unlocking spring helps the automatic reset of the unlocking rod.

[0013] Optionally, the mounting base further has an arrangement groove for arranging the unlocking spring and the unlocking nut.

[0014] By adopting the technical scheme, the arrangement groove is arranged, so that the structure of the unlocking mechanism is more compact, and the unlocking mechanism can accurately cooperate with the elastic locking assembly, thereby realizing the quick mounting and dismounting of the mounting base and the mounting plate.

[0015] Optionally, the top of the plug-in groove is provided with a driving spring for abutting against the plug-in convex column and driving the plug-in convex column to always be out of the plug-in groove.

[0016] By adopting the technical scheme, the elastic member is arranged at the top of the plug-in groove, and the top surface of the plug-in convex column abuts against the elastic member, so that the plug-in convex column always has the tendency to be out of the plug-in groove, which is helpful for the operator to separate the clamping plate and the abutting plate.

[0017] Optionally, the clamping driving assembly comprises a clamping cylinder and a transmission connecting rod set for transmission connecting the clamping cylinder and the clamping block, and the clamping block has an arc-shaped groove matched with the surface of the ejector tube.

[0018] By adopting the technical scheme, the specific structure of the clamping driving assembly is disclosed, and the accurate and quick clamping of the clamping block on the ejector tube is realized through the driving of the clamping cylinder on the clamping block.

[0020] By adopting the technical scheme, the clamping block comprises a first clamping block and a second clamping block, the telescopic adjustment of the clamping block is realized through the cooperation between the adjusting hole on the first clamping block and the mounting through hole on the second clamping block, thereby the clamping of the different ejection pipes is adapted, and the probability of the ejection pipe from moving in the machining process is reduced.

[0021] Optionally, the mounting base has a layout groove for arranging the ejection pipe, the layout groove comprises a first machining groove matched with the ejection pipe body and a second machining groove for abutting the bottom surface of the first connecting plate.
