DETAILED DESCRIPTION

[0027] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0030] like Figure 1-3 As shown, the utility model specifically relates to a milling fixture for an oil pan, comprising a base 100, wherein the upper end of the base 100 is provided with a clamping assembly capable of abutting against the oil pan;

[0031] The clamping assembly includes a vertical plate 241 arranged on the base 100, a bearing block 242 and a pressing block 243 arranged on the vertical plate 241. The side wall of the vertical plate 241 is provided with a through groove for the bearing block 242 to pass through. The bearing block 242 is inserted into the through groove and can move linearly relative to the vertical plate 241; the pressing block 243 is detachably arranged on the upper end surface of the vertical plate 241, and the end of the bearing block 242 is provided with a supporting column used in conjunction with the pressing block 243. The pressing block 243 and the supporting column are used in conjunction with each other to fix the edge of the oil pan placed between the pressing block 243 and the supporting column.

[0032] It should be noted that the vertical plate 241 is fixed on the base 100, and the vertical plate 241 is provided with a through groove, one end of the supporting block 242 passes through the through groove and extends out of the vertical plate 241, and is fixed by bolts. When the relative position of the supporting block 242 and the vertical plate 241 needs to be adjusted, the supporting block 242 is moved in the through groove by adjusting the tightness of the bolts.

[0033] A support column for abutting the bottom of the oil pan is provided at the end of the through groove, and the lower end surface of the oil pan at the edge is abutted by the support column, and the upper end surface of the oil pan is fixed by a pressure block 243 detachably provided on the upper end of the vertical plate 241, thereby fixing the edge of the oil pan.

[0034] A limiting column 2422 is also provided at the end of the bearing block 242. The limiting column 2422 is located between the support and the vertical plate 241. The position of the oil pan is limited by the limiting column 2422 to ensure processing accuracy and avoid the clamping assembly from abutting against other parts of the oil pan to affect the processing accuracy.

[0035] The height of the limiting column 2422 is greater than the height of the supporting column, and the upper end surface of the limiting column 2422 is lower than the upper end surface of the vertical plate 241 .

[0036] By arranging the limiting pillars 2422 and the supporting pillars in a stepped shape, the oil pan is limited under the premise that the edges of the oil pan are sufficiently supported, which not only ensures the processing accuracy of the oil pan, but also ensures the stability of the oil pan during processing.

[0037] The pressing block 243 is an L-shaped structure. A transverse groove 2432 for bolts to pass through is provided at the upper end of the pressing block 243. The pressing block 243 is detachably connected to the vertical plate 241 by bolts.

[0038] It should be noted that when the relative position of the pressing block 243 and the vertical plate 241 needs to be adjusted, the bolts are first loosened, and the pressing block 243 can move relative to the vertical plate 241, and at the same time, the bolts are moved in the transverse groove 2432. When the bolts are loosened, not only can the pressing block 243 be moved linearly to adjust the relative position of the pressing block 243 and the vertical plate 241, but also the relative angle between the pressing block 243 and the vertical plate 241 can be adjusted. After the position of the pressing block 243 is adjusted according to the size or model of the oil pan, the pressing block 243 is fixed by tightening the bolts, and then the edge of the oil pan can be fixed.

[0039] The pressing block 243 includes a pressing tongue and a support block fixed to one end of the pressing tongue. The pressing tongue and the support block are an integrally formed structure, and the other end of the pressing tongue abuts against the edge of the oil pan, and one end of the support block abuts against the bearing block 242.

[0040] When the edge of the oil pan needs to be fixed, first loosen the bolts, adjust the relative positions of the pressing block 243 and the vertical plate 241, so that the pressing tongue abuts against the edge of the oil pan, and tighten the bolts. At this time, the support block abuts against the bearing block 242. In order to ensure the stability of the oil pan, the upper end surface of the pressing tongue is parallel to the upper end surface of the vertical plate 241. Only in this way can the pressing block 243 be stable, thereby ensuring the firmness of the edge of the oil pan.

[0041] The clamping assemblies are provided in four and include a first clamping assembly 230, a second clamping assembly 240, a third clamping assembly 210 and a fourth clamping assembly 220, and two clamping assemblies are defined as a group. The clamping assemblies are provided in two groups, and the two groups of the clamping assemblies are arranged opposite to each other to fix the oil pan placed between the two groups of clamping assemblies.

[0042] The relative position of the oil pan is fixed by four clamping components, so that the oil pan can be stabilized and the processing accuracy is guaranteed.

[0043] The support column is detachably disposed at the end of the bearing block 242 .

[0044] The bearing block 242 is provided with an internal thread, and the support column is provided with an external thread used in conjunction with the internal thread. The support column is threadedly connected to the bearing block 242 .

[0045] Personnel can adjust the position of the support column relative to the bearing block 242 according to the size of the oil pan, and then lift the oil pan to avoid rigid contact between the lower end surface of the oil pan and the base 100, thereby ensuring the processing accuracy under the premise of perfectly bearing the processing cutting force.

[0046] In addition, the support column of the first clamping assembly 230 and the second clamping assembly 240 is defined as the first support column 2421, and the first support is threadedly adjusted downward from the upper end surface of the bearing block 242; the support column of the third clamping assembly 210 and the fourth clamping assembly 220 is defined as the second support column 211, and the second support is threadedly adjusted upward from the lower end surface of the bearing block 242, so as to lift the oil pan and at the same time ensure the flatness of the main mating surface of the oil pan during processing.

[0047] The base 100 further includes a positioning block 300 , which is arranged on the base 100 . The positioning block 300 further defines the position of the oil pan, thereby ensuring the machining accuracy.

[0048] The oil pan includes a shell 400 , and a pressing groove 410 is provided at the edge of the shell 400 for use with the pressing block 243 . The pressing block 243 abuts against the pressing groove 410 to fix the oil pan.

[0049] During the processing, the pressing tongue abuts against the pressing groove 410 to fix the oil pan.

[0050] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solution of the present invention rather than to limit it. The protection scope of the present invention is not limited thereto. Although the present invention is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the aforementioned embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution of the embodiment of the present invention, and should all be covered within the protection scope of the present invention.
