[0027] The following describes in detail a gear pump housing outer end face auxiliary processing tooling provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it is hereby explained that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative ways for implementation; and the accompanying drawings part is only for more specifically describing the embodiments and is not intended to specifically limit the present utility model.
[0028] Such as Figure 1 -Figure 5 As shown in the figure, an embodiment of the present utility model provides an auxiliary processing tooling for the outer end face of a gear pump housing, including a base 1 with a box-shaped structure. An installation groove 11 is provided on the top side wall of the base 1; a workbench 2 is clamped inside the installation groove 11. A first chute 22 and a second chute 23 distributed in a cross shape are provided on the top of the workbench 2. Among them, there are two first chutes 22 and two second chutes 23, and they are respectively distributed collinearly; a clamping assembly 3 is slidably connected in cooperation with the first chute 22. There are two clamping assemblies 3, and they are symmetrically distributed about the center; an adjusting assembly 4 is slidably connected in cooperation with the second chute 23. There are two adjusting assemblies 4, and they are symmetrically distributed about the center.
[0029] By arranging two adjusting assemblies 4 to abut against the arc-shaped surfaces at both ends of the end cover and contract inward, and at the same time cooperating with two clamping assemblies 3 to abut against the parallel surfaces on both sides of the end cover, the two cooperate to realize central clamping of the end face to be processed.
[0030] As Figure 2 shown, a plurality of strip-shaped grooves 21 distributed at equal intervals and in parallel are provided on the top of the workbench 2. The strip-shaped grooves 21 are parallel to the second chute 23. Slideways 24 are provided on both sides of the second chute 23. Among them, the second chute 23 straddles two strip-shaped grooves 21, and the slideways 24 are located at the bottom of the strip-shaped grooves 21 on both sides of the second chute 23.
[0031] By arranging the strip-shaped grooves 21, while providing a place to place the end cover, a gap is reserved at its bottom, reducing the sliding friction force when the end cover is adjusted and slid, and at the same time, it can temporarily collect the debris generated by the drilling work, avoiding the debris being clamped between the workbench 2 and the workpiece and rubbing and damaging the surface of the end cover.
[0032] As Figure 3 shown, it further includes two rotating seats 81, which are respectively fixedly connected to the bottom of the workbench 2 at both ends of the first chute 22. A bidirectional lead screw 82 is rotatably connected between the two rotating seats 81.
[0033] Among them, the bidirectional lead screw 82 is distributed parallel to the first chute 22, and the bidirectional lead screw 82 is located directly below the first chute 22
[0034] As Figure 2 and Figure 3 shown, it further includes a first motor 51, which is fixedly connected to the outer side wall of one of the rotating seats 81. The output end of the first motor 51 is fixedly connected to one end of the bidirectional lead screw 82. A through groove 12 for fitting and installing the first motor 51 is provided on the top of the side wall of the base 1.
[0035] By arranging the first motor 51 to drive the bidirectional lead screw 82 to rotate, and by arranging the through groove 12, it is convenient to install the workbench 2.
[0036] AsFigure 4 As shown, the clamping assembly 3 includes a first slider 31, on which a threaded hole 32 is provided and is threadedly connected to the bidirectional lead screw 82. The top of the first slider 31 is fixedly connected to a clamping plate 34 through a connecting plate 33. The clamping plate 34 is located on the top of the workbench 2, and the connecting plate 33 is slidably connected in cooperation with the first chute 22.
[0037] By setting the first slider 31 to be threadedly connected to the bidirectional lead screw 82, during operation, the top of the first slider 31 contacts and slides against the bottom of the workbench 2 for rotational limitation, thereby realizing the contraction and expansion actions of the two clamping assemblies 3.
[0038] As Figure 3 shown, it further includes a bracket 71, which is fixedly connected to the center position of the bottom of the workbench 2. The bracket 71 has a trapezoidal frame structure, and a bottom plate structure is provided at the center position of the bottom. Each strut on the bracket 71 avoids the first chute 22 and the second chute 23 and is fixedly connected to the bottom of the workbench 2 for avoiding the bidirectional lead screw 82 and the clamping assembly 3. The bottom of the bracket 71 is rotatably connected to a lead screw 72 in a vertical shape, and the bottom end of the lead screw 72 is rotatably connected in cooperation with the center position of the bottom of the base 1. A driven gear 62 is fixedly connected to the lead screw 72 near the bottom position.
[0039] As Figure 3 shown, it further includes a second motor 52, which is fixedly connected to the inner bottom of the base 1 through a mounting seat 53. A driving gear 61 is provided at the output end of the mounting seat 53, and the driving gear 61 is meshed and connected with the driven gear 62 in cooperation.
[0040] By setting the second motor 52 to drive the driving gear 61 to rotate, and in cooperation with the meshing of the driven gear 62, the lead screw 72 is driven to rotate.
[0041] As Figure 5 shown, the adjusting assembly 4 includes a second slider 41. The top of the second slider 41 is provided with an adjusting plate 44. The adjusting plate 44 is located on the top of the workbench 2. Four rollers 43 are provided in a rectangular array near the bottom of both sides of the second slider 41. The rollers 43 are in rolling connection with the slideway 24. A rotating shaft 42 is provided at the bottom of the second slider 41.
[0042] By setting the rollers 43 to be in rolling connection with the slideway 24, the sliding friction of the adjusting assembly 4 is reduced.
[0043] As Figure 3 shown, it further includes a nut seat 73, which is threadedly connected to the lead screw 72 in cooperation. Ear plates are symmetrically provided on the side wall of the lead screw 72; it further includes a connecting rod 74. One end of the connecting rod 74 is rotatably connected to the nut seat 73 through the ear plate, and the other end of the connecting rod 74 is rotatably connected to the rotating shaft 42. Two connecting rods 74 are provided and are symmetrically distributed.
[0044] By setting the connecting rod 74, when the lead screw 72 rotates, the nut seat 73 cannot rotate under the limiting action of the two connecting rods 74, and thus performs a linear displacement in the up and down directions. When the nut seat 73 moves downward, the two adjusting components 4 are pulled closer and contracted under the pulling action of the connecting rod 74.
[0045] For the technical solution provided by the present utility model, when performing the end cover tooling, first place the end cover to be drilled on the top of the workbench 2, and make the curved end face of the end cover face the two adjusting components 4 on both sides. Start the first motor 51 to drive the bidirectional lead screw 82 to rotate, drive the two clamping components 3 to move relatively closer to the straight surfaces on both sides of the end cover, and turn off the first motor 51, so that the arc surface directions at both ends of the end cover are parallel to the connection line of the two adjusting components 4. At this time, the clamping components 3 do not clamp the end cover. Subsequently, start the second motor 52 to drive the driving gear 61 to rotate, cooperate with the meshing of the driven gear 62, and then drive the lead screw 72 to rotate. At the same time, the nut seat 73 moves downward, so that the two adjusting components 4 converge and tightly adhere to the arc surfaces at both ends of the end cover, and drive the end cover to slide, so that the end cover is centrosymmetric in the connection line direction of the two adjusting components 4. Finally, start the first motor 51, tighten the clamping components 3 to clamp the end cover, and continuously apply pressure to complete the tooling.

In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components and circuits are not described in detail.
[0047] The above are only the preferred embodiments of the present utility model.
