Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] See Figures 1 to 5 This utility model provides a combined drilling part fixing fixture, including a movable connector 2, a fixture base 1, and a tooling fixture mold 7. The movable connector 2 includes a first movable seat 21 and a second movable seat 25 arranged opposite to each other. The first movable seat 21 is provided with a first connecting frame 3, and the first connecting frame 3 is provided with a first adjusting stand 5. The second movable seat 25 is provided with a second connecting frame 4, and the second connecting frame 4 is provided with a second adjusting stand 6. The first adjusting stand 5 and the second adjusting stand 6 are simultaneously movably connected to the tooling fixture mold 7. The movable connector 2 is disposed on the fixture base 1. The first connecting seat 21 is connected to the tooling fixture mold 7 via a first connecting frame 21. The connecting structure of the connecting frame 3 establishes a connection to the first adjusting frame 5, and the second moving seat 25 establishes a connection to the second adjusting frame 6 through the connecting structure of the second connecting frame 4. This solution requires simultaneous adjustment of the two sets of moving seats to change the distance between the first moving seat 21 and the second moving seat 25 on the fixture base 1, so as to change the spacing between the first adjusting frame 5 and the second adjusting frame 6, in order to adapt to the installation and use of tooling fixture molds 7 with different diameters. The tooling fixture mold 7 can be designed to match the diameter of the pump body end to be drilled. The tooling fixture mold 7 is fitted on the pump body, which makes it convenient for workers to manually and quickly drill the pump body.

[0027] See Figure 1 The movable connector 2 is slidably connected to the fixture base 1. The fixture base 1 has an adjustment groove 101 on its panel. The first movable seat 21 and the second movable seat 25 are respectively provided with a set of sliding blocks at the adjustment groove 101. The adjustment groove 101 has a center seat 102 in the center. The center seat 102 is movably connected to the adjustment groove 101. The movable connector 2 establishes a positional relationship with the first adjusting frame 5 and the second adjusting frame 6 respectively through the first movable seat 21 and the second movable seat 25. The first movable seat 21 and the second movable seat 25 move in the adjustment groove 101 through their respective sliding blocks to change the distance between the first movable seat 21 and the second movable seat 25. The center seat 102 is set to abut against the lower end of the pump body to be drilled to prevent the pump body limit from loosening. The specific structure of the center seat 102 connected to the fixture base 1 can be changed to adapt to the use of pump bodies with different diameters and heights.

[0028] The first connecting frame 3 is welded to the first movable seat 21, and the second connecting frame 4 is welded to the second movable seat 25. The first adjusting frame 5 and the second adjusting frame 6 are respectively provided with a set of fixing pins. While the first connecting frame 3 and the second connecting frame 4 are welded to each other, the connection strength between the first movable seat 21 and / or the second movable seat 25 and the first connecting frame 3 and / or the second connecting frame 4 is strengthened by a set of independent fixing pins, so as to avoid the support structure from becoming loose or shaking during the pump body drilling process.

[0029] See Figure 2 The first movable seat 21 has a first connecting seat 22 at one end. A first adjusting screw 24 is located on the side of the first connecting seat 22 near the second movable seat 25, passing through the second movable seat 25 and having a first positioning end. The second movable seat 25 has a second connecting seat at the end away from the first adjusting screw 24. A second adjusting screw 27 is located on the side of the second connecting seat near the first movable seat 21, passing through the first movable seat 21 and having a second positioning end. This controls the rotation of the first connecting seat 22, preventing axial linear displacement between the first connecting seat 22 and the first movable seat 21; that is, the first connecting seat 22 is always in contact with the first movable seat 25. When the movable seat 21 is in the connected state, it controls the rotation of the second connecting seat. The second connecting seat does not produce axial linear displacement with the second movable seat 25, that is, the second connecting seat is always in the connected state with the second movable seat 25. The first connecting seat 22 sets the first positioning end on the outside of the second movable seat 25, and the second connecting seat sets the second positioning end on the outside of the first movable seat 21. That is, no matter how the first connecting seat 22 rotates on the first movable seat 21, the first adjusting screw 24 will not disengage from the second movable seat 25, and no matter how the second connecting seat rotates on the second movable seat 25, the second adjusting screw 27 will not disengage from the first movable seat 21.

[0030] The first movable seat 21 and the second movable seat 25 change their distance under the rotation of the first connecting seat 22 and the second connecting seat, respectively. That is, the first adjusting screw 24 extends from the second movable seat 25 under the rotation, and the second adjusting screw 27 extends from the first movable seat 21 under the rotation. Then the first movable seat 21 and the second movable seat 25 run relative to each other, and the distance between them decreases, which can be used to fix a smaller pump body. If the first adjusting screw 24 reduces the extension amount from the second movable seat 25 under the rotation, and the second adjusting screw 27 reduces the extension amount from the first movable seat 21 under the rotation, then the first movable seat 21 and the second movable seat 25 run in opposite directions, and the distance between them increases, which can be used to fix a larger pump body.

[0031] The panel of the clamp base 1 is provided with an adjustment scale line 103 between the first movable seat 21 and the second movable seat 25. The displacement and spacing of the first movable seat 21 and the second movable seat 25 can be calibrated and adjusted, which can quickly adapt to the clamping and fixing of pump bodies of various specifications.

[0032] See Figure 3 The first connecting seat 22 has a first movable end 221 inside the first movable seat 21. The first movable end 221 is movably connected to the first movable seat 21. The outer tube wall of the first connecting seat 22 has a first reinforcing sleeve 222. The other end of the first reinforcing sleeve 222 has a first rotating handle 23. The first connecting seat 22 sets the first movable end 221 inside the first movable seat 21. That is, the first rotating handle 23 drives the first connecting seat 22 to rotate. The first movable end 221 always rotates within the accommodating cavity of the first movable seat 21 and does not generate displacement with the first movable seat 21. It only drives the first adjusting screw 24 to rotate, changing the distance between the first connecting seat 22 and the second movable seat 25. The first connecting seat 22 enhances the structural strength of the connecting rod of the first rotating handle 23 through the first reinforcing sleeve 222, avoiding the rotation control force on the first rotating handle 23 from affecting the structural strength of the connecting rod.

[0033] The arrangement of the second adjusting screw 27 and the second connecting seat is the same as that of the first connecting seat 22, and will not be described again here; the second connecting seat is provided with a second rotating handle 26 on the outside of the second moving seat 25. The second connecting seat is rotated by the second rotating handle 26, which changes the rotation of the second adjusting screw 27 and changes the distance between the first connecting seat 22 and the second moving seat 25.

[0034] Multiple sets of alignment ports are vertically arranged on the first adjusting stand 5 and the second adjusting stand 6 respectively. The size of each row of alignment ports and the spacing between adjacent ports are the same. That is, when the two sets of connecting and limiting stands 75 of the tooling fixture mold 7 need to be connected, the fixing pin is inserted into the target alignment port and the connecting port to restrict the pump body to be drilled between the fixture base 1 and the tooling fixture mold 7. The design of multiple sets of alignment ports enables the fixture assembly to adapt to the limiting drilling operation of pump bodies of different heights, thereby improving the applicability of the fixture assembly.

[0035] See Figure 4 and Figure 5The tooling fixture mold 7 includes an annular drilling mold sleeve 71. The top of the drilling mold sleeve 71 is provided with a pump body abutment panel 72. The pump body abutment panel 72 is provided with a drill bit extending into the mold hole 74. The bottom of the pump body abutment panel 72 is provided with a reserved positioning post 73. The inner cavity space of the drilling mold sleeve 71 is used to restrict the end of the pump body to be drilled. The top of the pump body abuts against the pump body abutment panel 72, and the end face of the pump body is aligned with the drill bit extending into the mold hole 74. The drill bit of the drilling machine extends into the mold hole 74 and drills out the structure at the corresponding position of the pump body, thereby obtaining a pump body with relevant drill holes that meet the production requirements. Before drilling, the pump body has a pre-set insertion hole that matches the reserved positioning post 73. When the reserved positioning post 73 is inserted into the insertion hole, the pump body can be accurately drilled.

[0036] The size and thickness of the drilling mold sleeve 71 of the tooling fixture mold 7, i.e. the diameter of the cavity between the drilling mold sleeves 71, can be designed according to specific drilling requirements. The position, spacing and specifications of the drill bit entering the mold hole 74 can be designed according to specific requirements, so that tooling fixture molds 7 of different specifications can be adapted to assemble with movable connecting parts 2 of different spacings, and complete the limit drilling treatment of pump body with different mode of assembly structure and different drilling requirements.

[0037] The reserved positioning post 73 has a marking strip 76 on the radially extended outer wall of the tooling fixture mold 7, which makes it easy for workers to quickly align and insert the reserved positioning post 73 into the insertion hole, and complete the quick alignment and installation of the tooling fixture mold 7 and the pump body.

[0038] The inner wall of the drilling die sleeve 71 is made of finely ground metal panel, and the top of the pump body abutment panel 72 is also made of finely ground metal panel. That is, the only contact surfaces between the entire fixing fixture structure and the pump body are the inner wall of the drilling die sleeve 71 and the top of the pump body abutment panel 72. The finely ground structures at these two locations will hardly cause frictional impact on the pump body and will not damage the non-drilling structures during the pump body drilling process.

[0039] The bottom of the drilling mold sleeve 71 is provided with two sets of connecting and limiting brackets 75. Each of the two sets of connecting and limiting brackets 75 has multiple sets of vertically arranged connecting ports. The tooling fixture mold 7 establishes a connection with the first adjusting bracket 5 and the second adjusting bracket 6 through the two sets of connecting and limiting brackets 75, which facilitates the quick assembly of the fixing fixture. Among them, after the exposed target connecting port is aligned with the pump body to be drilled, a positioning pin is inserted; after the hidden connecting port is aligned with a set of alignment ports, a connecting pin is inserted to establish a connection between the two sets of adjusting brackets, the tooling fixture mold 7 and the pump body to be drilled.

[0040] This utility model provides a combined drilling part fixing fixture, which includes a fixture base 1 and a movable connecting member 2 as the base, and two sets of adjusting uprights to establish a connection with the tooling fixture mold 7. The pump body to be drilled is restricted in the space formed between the center seat 102 and the drilling mold sleeve 71, so as to limit the pump body to align the surface to be drilled with the pump body abutting panel 72. The drill bit of the drilling machine extends into the mold hole 74 from the drill bit and drills out the excess tissue from the pump body to obtain the target drilling pump body.

[0041] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
