Description

Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to an auxiliary drilling fixture for a diaphragm pump column. Background Technology

[0002] A diaphragm pump is a new type of conveying machinery that can transport various corrosive liquids, liquids containing particles, and high-viscosity, volatile, flammable, and highly toxic liquids. Its structural feature is that two columns are mounted on both sides of the pump body, which, together with the intermediate body, form a diaphragm cavity for liquid transfer.

[0003] like Figures 2 to 3 The product 10 shown includes an arc-shaped body 11, multiple bolt holes 12 on the body 11, a column 13 passing through the body 11, two end faces 14 at both ends of the column 13, and a sealing ring groove 15 within the body 11. The body 11 is used to engage with the intermediate body of a diaphragm pump to form a membrane cavity for transporting liquid. The bolt holes 12 are used to fix the product 10 to both sides of the intermediate body of the diaphragm pump. The column 13 is used to connect pipelines for liquid delivery. The end faces 14 are used for pipeline connections to ensure a tight fit at the interface. The sealing ring groove 15 is located on the body 11 and inside the center of the arc-shaped structure to fill the sealing ring when the product 10 is engaged with the diaphragm pump.

[0004] In actual production, the product 10 is usually cast as a whole, so the main body 11 needs to be drilled to form the bolt fixing holes 12. However, due to the special shape of the product 10, conventional jigs are used for clamping, which makes it impossible to uniformly drill the angle. In addition, multiple sets of drilling jigs need to be designed for different sizes of the product 10, resulting in low drilling efficiency, low production capacity, and the inability to meet production requirements in terms of quality.

[0018] The specific embodiments of the utility model are further explained below. It should be understood that the explanation of the utility model embodiments herein is not used to limit the protection scope of the utility model.

[0019] As shown in the structure schematic view of the diaphragm pump stand auxiliary drilling tool provided by the utility model. The diaphragm pump stand auxiliary drilling tool includes a product 10, a tool mold sleeve 20 for placing the product 10, and a limiting structure 30 arranged on one side of the tool mold sleeve 20. It can be conceived that the diaphragm pump stand auxiliary drilling tool also includes other functional modules such as a feeding mechanism, a drilling mechanism and the like, which are the technology known to the person skilled in the art, and will not be repeated here. Figures 1 to 4 The tool mold sleeve 20 includes a tool bottom plate 21, at least one positioning convex strip 22 arranged on the tool bottom plate 21, and a plurality of drilling reserved holes 23 arranged on one side of the positioning convex strip 22.

[0020] The tool mold sleeve 20 includes a tool bottom plate 21, at least one positioning convex strip 22 arranged on the tool bottom plate 21, and a plurality of drilling reserved holes 23 arranged on one side of the positioning convex strip 22.​​​

[0021] The tooling base plate 21 is a disc-shaped structure, which is placed and fixed on the equipment plane or operation platform, and is used for positioning and fixing the product 10.

[0022] The positioning convex strip 22 is an annular convex strip arranged on the tooling base plate 21, which can be integrally formed with the tooling base plate 21, so that when the product 10 is placed on the tooling base plate 21, the sealing ring groove 15 is clamped on the positioning convex strip 22, which ensures that the product 10 does not shake and displace during drilling operation. Two openings can be arranged on the positioning convex strip 22 for easy taking, so as to prevent the product 10 from being adsorbed on the tooling base plate 21 due to buckling. In addition, multiple positioning convex strips 22 with different diameters can be arranged in concentric circles on the tooling base plate 21 to be compatible with multiple models, and the tooling repetition rate is high.

[0023] The drilling reserved hole 23 is a through hole penetrating through the tooling base plate 21, which is arranged in an annular array outside the positioning convex strip 22, and the annular diameter of the array is greater than the diameter of the positioning convex strip 22, so that after the product 10 is positioned and clamped by the positioning convex strip 22, the drilling tool can drill the surface of the product 10 through the drilling reserved hole 23. A circle of drilling reserved holes 23 is arranged outside the positioning convex strip 22 with different diameters to cooperate with the drilling operation of the product 10 with different sizes.

[0024] The limiting structure 30 includes a limiting base plate 31 arranged on one side of the tooling base plate 21, a sliding rail assembly 32 arranged on the limiting base plate, a connecting plate 33 arranged on the sliding rail assembly 32, a limiting plate 34 arranged on the connecting plate 33, and a locking handle 35 arranged on the connecting plate 33.

[0025] The limiting base plate 31 is fixedly connected to the tooling base plate 21 and located on one side of the tooling base plate 21, so as to serve as a base plate for bearing various components of the limiting structure 30.

[0026] The sliding rail assembly 32 includes a sliding rail 321 and a sliding block 322 arranged on the sliding rail 321. The extension direction of the sliding rail 321 is the radial direction of the tooling base plate 21, so that the sliding block 322 can slide towards the center of the tooling base plate 21.

[0027] The connecting plate 33 is a rectangular plate, which is fixed to the sliding block 322 by fasteners and is arranged in parallel and spaced apart from the limiting base plate 31. A threaded hole is formed in the end of the connecting plate 33 away from the tooling base plate 21, so as to insert the locking handle 35.

[0028] The limiting plate 34 is a rectangular plate, which is fixed at one end of the connecting plate 33 close to the tool base plate 21 and is arranged perpendicularly to the connecting plate 33, so that the product placed on the tool sleeve 20 cannot rotate by pushing the limiting plate 34 against the end face 14.

[0029] The locking handle 35 is connected to the connecting plate 33 by a bolt and penetrates the connecting plate 33, so that the sliding block 322 is locked by rotating the locking handle to tighten the bolt against the sliding rail 321.

[0030] In use, the product 10 to be processed is placed on the tool sleeve 20 and positioned by the positioning convex strip 22, then the connecting plate 33 is manually or mechanically driven to move, so that the limiting plate 34 is against the end face 14, the locking handle 35 is tightened to make the bolt against the sliding rail 321 to lock the product 10, and the drilling operation can be started.

[0031] Compared with the prior art, the diaphragm pump stand auxiliary drilling tool provided by the utility model can position and abut the product 10 through the sealing ring groove 15 and the positioning convex strip 22 and drill through the drilling reserved hole 23, so that the drilled opening angle is uniform and arranged in order, and the limiting structure 30 is arranged, the limiting plate 34 is against the end face 14, so that the product 10 is prevented from rotating and displacing during drilling, the drilling accuracy is ensured, and the good product rate of finished products is improved.

[0032] The above is only a preferred embodiment of the utility model and is not used to limit the protection scope of the utility model, any modification, equivalent replacement or improvement within the spirit of the utility model is covered in the claim scope of the utility model.
