[0002] In the field of mechanical processing, the oil pan is a key mechanical component, and its processing accuracy is directly related to the performance and reliability of mechanical equipment. The processing quality of the oil pan end face is particularly critical because it directly affects the matching accuracy and sealing performance of the oil pan and other engine components. Traditional oil pan processing fixtures have some limitations in practical applications, especially in terms of clamping stability. These limitations limit the improvement of processing efficiency and product quality.

[0003] The end surface of the oil pan is usually processed on a machine tool, and the traditional fixture can only provide clamping force in one direction. This one-way clamping method is difficult to adapt to complex and precise processing requirements. For example, when performing end milling or grinding, if the fixture cannot provide stable clamping, it may cause vibration and deviation during the processing, thus affecting the flatness and dimensional accuracy of the processed surface.

[0004] Therefore, in view of this, the inventor proposes an oil pan end surface machining fixture. Utility Model Content

[0009] The fixing plate is arranged on the upper surface of the oil pan placing platform. The fixing plate is provided with a limiting hole. The position of the limiting member is adjusted by the adjusting assembly so that the limiting member is threadedly matched with the limiting hole.

[0010] Furthermore, the clamping structure includes a base and a mechanical clamp, the mechanical clamp is fixedly mounted on the base, and the base is detachably mounted on the workbench.

[0011] Furthermore, the mechanical clamp includes a clamp and a mounting plate, the clamp is fixedly mounted on a side of the mounting plate close to the oil pan placement platform, and the mounting plate is fixedly connected to the base.

[0012] Furthermore, the mechanical clamp also includes a driving motor, which is fixedly mounted on a side of the mounting plate away from the oil pan placement platform and is used to drive the clamp to clamp the oil pan placement platform.

[0013] Furthermore, there are a plurality of clamping jaws, and a clamping block is provided at the end of each clamping jaw, and the clamping block is made of rubber material.

[0014] Furthermore, the positioning assembly includes a first positioning structure and a second positioning structure, the limiting member is fixedly mounted on the first positioning structure, and the first positioning structure is configured through the second positioning structure to be able to move away from or close to the oil pan placement platform in a first direction.

[0015] Furthermore, there are multiple limiting holes which are evenly distributed along the first direction, and the limiting member is configured to slide and adjust in the second direction through the first adjustment structure so that the limiting member is threadedly matched with one of the limiting holes.

[0017] The utility model proposes a clamp for machining the end face of an oil pan. By introducing a clamping structure on both sides and a rear limit structure, the device can provide a stable clamping force in multiple directions.

DETAILED DESCRIPTION

[0024] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0025] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0026] To solve the technical problem that the traditional clamps in the prior art can only provide clamping force in one direction, and this one-way clamping method is difficult to adapt to complex and precise processing requirements, such as Figures 1 to 3 As shown, this embodiment provides an oil pan end surface processing fixture 1, which is used to clamp the oil pan when processing the end surface of the oil pan, and the oil pan end surface processing fixture 1 is installed on a workbench 2. In this embodiment, the oil pan end surface processing fixture 1 preferably includes:

[0027] The oil pan placing platform 5, the oil pan placing platform 5 is provided with clamping structures 3 on both sides thereof. As a preferred solution of this embodiment, the clamping structures 3 are provided with two groups, one group on each side of the oil pan placing platform 5, so as to limit the oil pan in a first direction; and

[0028] The limiting structure 4 is arranged behind the oil pan placement platform 5. The limiting structure 4 includes a positioning assembly 41 and a limiting member 42. A fixing plate 51 is provided on the oil pan placement platform 5. A limiting hole 511 is formed on the fixing plate 51. The positioning assembly 41 is configured to adjust the position of the limiting member 42 so that the limiting member 42 is threadedly matched with the limiting hole 511. In this embodiment, the limiting member 42 is a limiting threaded rod, which is threadedly connected with the internal thread of the limiting hole 511, so as to limit the oil pan in the second direction. Through this design, the clamp of this embodiment can provide a stable clamping force in two main directions, effectively avoiding the problem of oil pan displacement or vibration that may occur when the traditional clamp is clamped in one direction, and significantly improving the processing accuracy and stability.

[0029] This embodiment is preferred, as Figure 2 As shown, the clamping structure 3 includes a base 31 and a mechanical clamp 32. The mechanical clamp 32 is fixedly mounted on the base 31. The base 31 is detachably mounted on the workbench 2. A slide groove is provided on the workbench 2 along the first direction. When in use, the screws on the base 31 can be removed to slide the base 31 along the slide groove, so that the position of the mechanical clamp 32 in the first direction is changed to adapt to different sizes of oil pans in the first direction to meet diverse processing requirements. This design not only improves the applicability of the fixture, but also facilitates the rapid adjustment and replacement of the oil pan, thereby improving work efficiency.

[0030] The mechanical clamp 32 includes a clamp 321 and a mounting plate 322. The clamp 321 is fixedly mounted on a side of the mounting plate 322 close to the oil pan placement platform 5. The mounting plate 322 is fixedly connected to the base 31. The mechanical clamp 32 also includes a drive motor 323. The drive motor 323 is fixedly mounted on a side of the mounting plate 322 away from the oil pan placement platform 5, and is used to drive the clamp 321 to clamp the oil pan placement platform 5. Through the precise control of the drive motor 323, the uniformity and stability of the clamping force can be ensured, and the problem of loose clamping or damage to the oil pan due to improper manual operation can be avoided.

[0031] There are multiple clamping jaws 321, and a clamping block 3211 is provided at the end of each clamping jaw 321. The clamping block 3211 is made of rubber. The clamping block 3211 made of rubber not only provides a good friction coefficient to ensure a stable clamping, but also the elasticity of the rubber can effectively protect the surface of the oil pan to avoid scratches or damage during the clamping process.

[0032] like Figure 1 to Figure 2As shown, the positioning assembly 41 includes a first positioning structure 43 and a second positioning structure 44, and the limiting member 42 is fixedly mounted on the first positioning structure 43. The first positioning structure 43 is configured to be able to move away from or approach the oil pan placement platform 5 in a first direction through the second positioning structure 44. Specifically, the second positioning structure 44 is provided with an adjusting threaded rod 441 and a second adjusting handle 442, and the second adjusting handle 442 is fixedly connected to the adjusting threaded rod 441. An adjusting block 431 is provided at the bottom of the first positioning structure 43, and a threaded hole is provided in the adjusting block 431. The adjusting threaded rod 441 is threadedly matched with the threaded hole, and the second adjusting handle 442 is rotated to make the first positioning structure 43 slide along the first direction to move away from or approach the oil pan placement platform 5, so that the positioning assembly 41 can flexibly adjust the position of the limiting member 42 to adapt to oil pans of different sizes and ensure that the position of the oil pan is accurate during the processing.

[0033] like Figure 1 to Figure 2 As shown, there are multiple limiting holes 511 evenly distributed along the first direction, and the limiting member 42 is configured to slide and adjust in the second direction through the first adjustment structure 43, so that the limiting member 42 is threadedly engaged with one of the limiting holes 511. The sliding part of the first adjustment structure 43 is similar to the second adjustment structure 44, and thus, not only multiple positioning points are provided to ensure the stability of the oil pan in the second direction, but also the position of the limiting member 42 can be accurately controlled by threaded engagement, further improving the processing accuracy and repeatability.

[0034] That is, this embodiment provides an oil pan end surface processing fixture 1, which can provide stable clamping force in multiple directions by introducing the clamping structures 3 on both sides and the rear limiting structure 4, and can realize accurate positioning of the oil pan by cooperating with the adjustable positioning component 41. The stability and precision of the processing process are improved by multi-directional clamping and accurate positioning of the oil pan, so that the fixture can adapt to various processing requirements, thereby effectively solving the technical problem that the traditional fixture in the prior art can only provide clamping force in one direction, and this unidirectional clamping method is difficult to adapt to complex and precise processing requirements.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
