Description

Technical Field

[0001] The utility model belongs to the technical field of drilling technology, in particular to a connecting frame drilling device. Background Art

[0002] The pump parts connecting bracket is used to connect the motor and pump body and other parts. The relative positions of the bolt holes on the flanges at both ends of the connecting bracket determine the relative positions of the motor and pump body and other parts in the assembly. When drilling holes in the connecting bracket, the existing technology has the following shortcomings:

[0003] First, there are two manual steps before drilling.

[0004] (1) The operator first drills the bolt holes on one side of the flange;

[0005] (2) The operator connects the pump body to the connecting bracket with a hole drilled on one side, then levels it with the motor, places it on the base, and marks the hole in the connecting bracket;

[0006] (3) Remove the connecting frame, put on the drilling jig, and drill holes at the marked lines;

[0007] (4) Furthermore, the marking and positioning quality may be affected due to the limited experience of the operator or the labor intensity.

[0008] Second, during the drilling process, the bolt holes on one side must be drilled first, and then, after assembly, the holes on the other side must be marked and disassembled before drilling. This results in non-interchangeability of connectors of the same specification, and low drilling efficiency. During the production and processing of connectors, the motor holes on one side must be drilled first, and then the holes on the other side are drilled during assembly. Similarly, when producing aftermarket parts, the holes on the other side must be reshaped into waist-shaped holes, making the connectors non-interchangeable and reducing their strength. Summary of the Invention

[0009] The purpose of this utility model is to provide a connecting frame drilling device that improves drilling accuracy and interchangeability of connecting frames. The technical solution adopted is as follows:

[0010] A connecting frame drilling device, comprising:

[0011] A No. 1 drill template 1 is provided with a No. 1 drill sleeve hole 102 and a No. 1 positioning rod hole 103. A No. 1 drill sleeve 101 is sleeved in the No. 1 drill sleeve hole 102. The inner hole of the No. 1 drill sleeve hole 102 is corresponding to the through hole on the No. 1 flange.

[0012] The second drilling template 3 is provided with a second drill sleeve hole 302 and a second positioning rod hole 303. The second drill sleeve 301 is sleeved in the second drill sleeve hole 302. The inner hole of the second drill sleeve hole 301 is corresponding to the through hole on the second flange.

[0013] When drilling the connecting frame for the first time, the second drilling template 3 is located on the connecting frame and is set upwards;

[0014] When drilling the connecting frame for the second time, the No. 1 drilling template 1 is located on the connecting frame and above the No. 2 drilling template 3;

[0015] Positioning rod 2, downwardly passes through the first positioning rod hole 103, the inner cavity of the connecting frame and the second positioning rod hole 303 in sequence;

[0016] and fixing device, connecting the connecting frame and No. 2 drilling template 3.

[0017] Preferably, the No. 1 drilling template 1 includes a No. 1 eccentric lug 104 and a No. 1 boss 105;

[0018] The first eccentric lug 104 is provided on the outer circle of the first boss 105; the first eccentric lug 104 defines the first positioning rod hole 103;

[0019] The No. 1 boss 105 is matched with the No. 1 inner stop of the connecting frame, and the No. 1 eccentric lug 104 is provided with the No. 1 drill sleeve hole 102 .

[0020] Preferably, the first eccentric lug 104 and the first boss 105 are integrally formed.

[0021] Preferably, the second drilling template 3 includes a second eccentric lug 304 and a second boss 305;

[0022] The second boss 305 is formed on the second non-planar lug 304;

[0023] The second boss 305 is matched with the second inner stop of the connecting frame, and the second eccentric lug 304 is provided with the second drill sleeve hole 302 .

[0024] Preferably, the fixing device includes a locking bolt 4 and a nut 5 matched with one end of the locking bolt 4 .

[0025] Preferably, the number of the positioning rods 2 is 2 and they are symmetrically distributed about the connecting frame.

[0026] Compared with the prior art, the advantages of the present invention are:

[0027] 1. When drilling holes in the connecting frame, first mate the boss of the drilling template with the stop of the connecting frame, and drill a hole on one side through the drilling template and the drill sleeve; pass the locking bolt through the threaded sleeve on the drilling template and secure it with a nut, turn it 180°, insert the two positioning rods into the drilling template, and then mate another drilling template with the stop of the connecting frame through the positioning rod and the boss to drill a hole on the other side.

[0028] As a result, the need for marking and drilling, milling waist-shaped holes, etc. is avoided, and the drilling error is reduced, thereby improving the drilling accuracy, reducing labor intensity, and improving work efficiency.

[0029] 2. Improved the interchangeability of the connecting frame.

[0030] Since the inner hole of the drill sleeve is arranged correspondingly to the through hole on the flange, the inner diameter of the drill sleeve has various specifications.

[0031] Since the through-holes on different flanges have different specifications, a drill sleeve corresponding to the specific specifications of the flange can be selected. Therefore, the connecting frame can be applicable to first flanges and second flanges of various specifications, thereby increasing its interchangeability.

[0032] 3. This device is also suitable for drilling parts that need to ensure the relative positions of the bolt holes at both ends. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is a more detailed description of a connecting frame drilling device according to the present invention, with reference to schematic diagrams. These diagrams illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention as described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as a general guideline for those skilled in the art and not as a limitation of the present invention.

[0039] like Figure 1 As shown, a connecting frame drilling device includes:

[0040] A No. 1 drill template 1 is provided with a No. 1 drill sleeve hole 102 and a No. 1 positioning rod hole 103. A No. 1 drill sleeve 101 is sleeved in the No. 1 drill sleeve hole 102. The inner hole of the No. 1 drill sleeve hole 102 is corresponding to the through hole on the No. 1 flange.

[0041] The second drilling template 3 is provided with a second drill sleeve hole 302 and a second positioning rod hole 303. The second drill sleeve 301 is sleeved in the second drill sleeve hole 302. The inner hole of the second drill sleeve hole 301 is corresponding to the through hole on the second flange.

[0042] When drilling the connecting frame for the first time, the second drilling template 3 is located on the connecting frame and is set upwards;

[0043] When drilling the connecting frame for the second time, the No. 1 drilling template 1 is located on the connecting frame and above the No. 2 drilling template 3;

[0044] Positioning rod 2, downwardly passes through the first positioning rod hole 103, the inner cavity of the connecting frame and the second positioning rod hole 303 in sequence;

[0045] And a fixing device, connecting the connecting frame and the second drilling template 3. The fixing device further improves the stability of the second drilling template 3 on the connecting frame, thereby reducing the drilling error.

[0046] Specifically, the No. 1 drilling template 1 includes a No. 1 unequal-surface lug 104 and a No. 1 boss 105 ; the No. 1 unequal-surface lug 104 and the No. 1 boss 105 are integrally formed, thereby improving the mechanical strength and stability of the No. 1 drilling template 1 .

[0047] The first eccentric lug 104 is disposed on the outer circumference of the first boss 105; the first eccentric lug 104 defines a first positioning rod hole 103;

[0048] The No. 1 boss 105 is matched with the No. 1 inner stop of the connecting frame, and the No. 1 convex ear 104 is provided with a No. 1 drill hole 102 .

[0049] The second drilling template 3 includes a second unequal-surface lug 304 and a second boss 305 , which are integrally formed, thereby improving the mechanical strength and stability of the second drilling template 3 .

[0050] The second boss 305 is formed on the second non-conforming lug 304;

[0051] The second boss 305 is matched with the second inner stop of the connecting frame, and the second eccentric lug 304 is provided with a second drill sleeve hole 302.

[0052] In this embodiment, the fixing device includes a locking bolt 4 and a nut 5 that cooperates with one end of the locking bolt 4. The number of nuts 5, that is, the number of locking bolts 4, is three.

[0053] Furthermore, the number of the positioning rods 2 is 2 and they are symmetrically distributed about the connecting frame.

[0054] In this embodiment, the No. 1 drill sleeve 101 is embedded (interference fit) in the No. 1 drill sleeve hole 102, and the No. 2 drill sleeve 301 is embedded in the No. 2 drill sleeve hole 302, thereby improving the stability of the No. 1 drill sleeve 101 in the No. 1 drill sleeve hole 102 and the No. 2 drill sleeve 301 inside the No. 2 drill sleeve hole 302, thereby further reducing the drilling error.

[0055] The drill sleeve 101 is embedded in the drill sleeve hole 102 , and the machining accuracy can be guaranteed relative to the “clearance fit between the drill sleeve 101 and the drill sleeve hole 102 ”.

[0056] The No. 1 drilling template 1 and the No. 2 drilling template 3 are both adapted to the corresponding flanges.

[0057] Taking drilling template No. 1 as an example, the following describes how to adapt to the corresponding flange:

[0058] The centerline of the No. 1 drill sleeve hole 102 on the No. 1 drill template 1 is located at the same position as the centerline of the through hole on the No. 1 flange;

[0059] The centerline of the No. 1 drill sleeve 101 on the No. 1 drill template 1 is located at the same position as the centerline of the No. 1 drill sleeve hole 102 .

[0060] The inner diameter of the No. 1 drill sleeve 101 on the No. 1 drill template 1 is the same as the inner diameter of the through hole on the No. 1 flange.

[0061] Furthermore, if the centerline positions of the through holes on flange No. 1 remain the same, but only the through hole sizes differ, a different size of drill template No. 1 can be replaced without removing the drill sleeve to ensure positioning accuracy. This means that a drill sleeve of the same size is always mounted on the corresponding flange.

[0062] Similarly, if the centerline position of the through hole of flange No. 2 is the same and only the hole size is different, the No. 2 drill template 3 of different specifications can be replaced. The drill sleeve does not need to be removed during the replacement process to ensure positioning accuracy.

[0063] In this embodiment, the No. 1 drilling template 1 is used to process the through hole corresponding to the pump body flange (No. 1 flange), and the No. 2 drilling template 1 is used to process the through hole corresponding to the motor flange.

[0064] In other embodiments, the No. 1 drilling template 1 is used to process the through hole corresponding to the motor flange (No. 2 flange), and the No. 2 drilling template 1 is used to process the through hole corresponding to the pump body flange.

[0065] Working principle of a connecting frame drilling device:

[0066] Step 1: Place the connecting frame with the end connected to the second flange facing upward.

[0067] Step 2: Place the No. 2 drill template 3 on the connecting frame, and place the No. 2 drill sleeve 301 in the corresponding No. 2 drill sleeve hole 302.

[0068] Step 3: Drilling with a tool. The tool can move in three directions: X, Y, and Z.

[0069] Step 4: Fix the No. 2 drilling template 3 to the connecting frame by tightening the bolts 4 and nuts 5.

[0070] That is, the locking bolt 4 is passed through the through holes that have been processed on the No. 2 drill sleeve 302 and the No. 2 flange, and then the nut is matched with the locking bolt 4.

[0071] Step 5. Turn the connecting frame 180 degrees and place the end of the connecting frame connected to flange No. 1 facing upwards. Figure 1 shown.

[0072] Figure 1 In the figure, only one of the through holes that have been machined on flange No. 2 is shown, and the others are not shown.

[0073] Step 6: Install the positioning rod 2 to radially position the No. 1 drilling template 1 and the No. 2 drilling template 3 on the connecting frame.

[0074] The No. 1 drilling template 1 is provided with a No. 1 positioning rod hole 103 that cooperates with the positioning rod 2, and the No. 2 drilling template 3 is provided with a No. 2 positioning rod hole 303 that cooperates with the positioning rod 2, and then the positioning rod 2 passes through the No. 1 positioning rod hole 103 and the No. 2 positioning rod hole 303 on the drilling template 1 and the drilling template 3 respectively.

[0075] Step 7: Place the No. 1 drill template 1 on the connecting frame, and place the No. 1 drill sleeve 101 in the corresponding No. 1 drill sleeve hole 102.

[0076] Step 8: Drilling with a tool. The tool can move in three directions: X, Y, and Z.

[0077] Figure 1 Among them, only one of the No. 1 drill sleeve holes 102 on the No. 1 flange is shown, and the others are not shown.

[0078] In other embodiments other than this embodiment, the first drilling may also be performed based on the No. 1 drilling template 1 .
