[0002] Precision machining of clutch housings plays an important role in automobile manufacturing. Clutch housings need to go through multiple machining processes, involving separate processing of the front and back sides; in the traditional machining process, changing the fixed surface of the clutch housing to complete the machining of the front and back sides often relies on multiple sets of fixtures, or requires the operator to manually adjust the position of the fixtures. This approach is not only time-consuming and labor-intensive, but also prone to positioning errors, resulting in reduced machining accuracy and poor product consistency.

[0003] Existing universal fixture designs usually focus on fixing in a single posture and lack the flexibility to accommodate the different geometric features of the front and back sides of the shell. Purchasing multiple sets of fixtures increases the company's equipment investment costs and also limits the improvement of production efficiency. Especially in the field of modern automotive parts manufacturing that pursues high efficiency and high quality, frequent fixture replacement or positioning adjustments not only slows down the production cycle, but may also introduce human operational errors, affecting product quality stability and production efficiency.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Reference Figure 1 , Figure 2 The utility model provides a clamp for processing a clutch housing, comprising a base plate 1, a plurality of supporting mechanisms 2 are installed on the upper surface of the base plate 1, the upper ends of the supporting mechanisms 2 are inserted into bolt holes of a clutch housing 3 to fix the base plate 1, a slide groove 101 is provided on the lower surface of the base plate 1, a slider 5 and a screw rod 4 are installed in the slide groove 101, the screw rod 4 is threadedly matched with the slider 5 to drive it to slide in the slide groove 101; in actual applications, the screw rod 4 is replaced by a power component such as a cylinder or an oil cylinder.

[0020] Reference Figure 3 , Figure 4 The support mechanism 2 includes a support column 201, a telescopic cavity 202 is arranged in the support column 201, and the cross section of the telescopic cavity 202 is designed to be elliptical. A locking column 204 that penetrates the support column 201 is installed in the telescopic cavity 202. A reset spring 203 and a locking disk 206 are arranged on the locking column 204 in the telescopic cavity 202. The upper end of the reset spring 203 is rotatably connected to the locking column 204, and the lower end is connected to the bottom of the telescopic cavity 202. The locking disk 206 is elliptical and its short axis is less than or equal to the length of the telescopic cavity 202. The short axis of the locking plate 206 is smaller than the long axis of the telescopic cavity 202 and larger than the short axis of the telescopic cavity 202. When the locking column 204 rotates in the telescopic cavity 202, the long axis of the locking plate 206 is aligned with the long axis of the telescopic cavity 202, and the locking plate 206 can slide freely in the telescopic cavity 202. When the long axis of the locking plate 206 rotates toward the short axis of the telescopic cavity 202, the outer annular surface of the locking plate 206 is pressed against the inner wall of the telescopic cavity 202, thereby fixing the locking column 204 on the support column 201.

[0021] The upper end of the locking column 204 is provided with a connecting plate 205, which is eccentrically arranged on the locking column 204. A limiting column 207 is installed on the locking column 204 between the locking plate 206 and the connecting plate 205. The cross section of the limiting column 207 is an elliptical shape that matches the telescopic cavity 202. A connecting sleeve 7 is also provided on the lower surface of the bottom plate 1. The connecting sleeve 7 is threadedly connected to the lower end of the support column 201 so that the two are fixed to the bottom plate 1. A bearing 8 is installed in the connecting sleeve 7. The outer ring of the bearing 8 is fixedly connected to the connecting sleeve 7. The inner ring is provided with a spline sleeve 9. The spline sleeve 9 is splined with the lower end of the locking column 204. A push rod 6 is installed on the spline sleeve 9. One end of the push rod 6 is connected to the spline sleeve 9, and the other end is provided with a strip through hole 601. A limiting bolt 10 is provided on the slider 5. The limiting bolt 10 passes through the strip through hole 601 and is connected to the slider 5.

[0022] Before connection, the reset spring 203 is in a free state, the connecting plate 205 is inserted into the bolt hole of the clutch housing 3, and the upper end of the limiting column 207 abuts against the outer edge of the bolt hole of the clutch housing 3 to play a limiting and supporting role, pressing the clutch housing 3 downward so that its mating surface remains parallel to the bottom plate 1. This process can be achieved with the aid of external equipment; then, by rotating the screw 4, the slider 5 is driven to slide in the slide groove 101, and then through the cooperation of the limiting bolt 10 and the strip through hole 601, the push rod 6 is driven to drive the spline sleeve 9 to rotate. When the locking column 204 rotates, the outer annular surface of the locking plate 206 is tightly pressed against the inner wall of the telescopic cavity 202 to fix the locking column 204 on the support column 201. At the same time, the eccentric position of the connecting plate 205 can produce a lever effect, thereby achieving a stable connection with the clutch housing.

[0023] Since the position of the bolt hole of the clutch housing 3 relative to the base plate 1 remains unchanged during forward and reverse installation, the retractable locking column 204 makes up for the height difference between the outer edge of the bolt hole and the base plate 1 during forward and reverse installation, thereby achieving the fixation of the front and back sides of the clutch housing 3 by the same set of clamps.

[0024] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
