For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a base connection hole processing device for a rear support of an automobile engine in this embodiment includes a base plate 1, a connecting block 2 and a clamping device 3. A first support plate 4 and a second support plate 5 are arranged above the base plate 1. One end of the connecting block 2 is fixedly connected to the first support plate 4, and the other end is fixedly connected to the second support plate 5. The clamping device 3 includes a clamping block 31. Columnar clamping blocks 32 are arranged at both ends of the bottom of the clamping block 31. The columnar clamping block 32 is a hollow cylinder. The columnar clamping block 32 is fixedly connected to the clamping block 31. The clamping block 31 is connected to the connecting block 2 by bolts 33.

[0021] The working principle of the utility model is as follows: rear brackets are placed on both sides of the connecting block 2, and the rear brackets are placed above the first support plate 4 and the second support plate 5, and the front bracket of the rear bracket is located below the base and between the first support plate 4 and the second support plate; the columnar pressing block 32 of the clamping device 3 is placed in the weight-reducing groove of the front bracket, and the side wall of the columnar pressing block 32 is squeezed with the notch of the weight-reducing groove, and under the action of the locking bolt 33, the pressing block 31 is fixed, so that the columnar pressing blocks 32 at both ends respectively clamp and fix the rear brackets on both sides of the connecting block 2, which is convenient for drilling and countersinking of the base connection hole.

[0022] A baffle is provided above the first support plate 4, and the baffle is integrally formed with the first support plate 4. After the base of the rear bracket 6 is placed above the first support plate 4 and the second support plate 5, one side of the base abuts against the inner side of the baffle, and the other side can abut against the side of the connecting block 2, thereby realizing the positioning of the rear bracket and ensuring the drilling or countersinking accuracy of the connecting hole of the product base.

[0023] The distance between the first support plate 4 and the second support plate 5 is greater than the thickness d of the front bracket 62 of the rear bracket 6 and less than the length l of the base 61. After the base of the rear bracket is placed above the first support plate 4 and the second support plate 5, the front bracket 62 is located below and between the first support plate 4 and the second support plate 5. The distance is greater than the thickness d of the front bracket 62, which is conducive to placing the front bracket 62 between the first support plate 4 and the second support plate 5. The distance is less than the length l of the base 61, which is conducive to placing the edge and connecting hole of the base 61 on the first support plate 4 and the second support plate 5.

[0024] A groove 7 is provided on the top of the first support plate 4 and the second support plate 5. After the rear bracket is fixed above the first support plate 4 and the second support plate 5, the groove 7 corresponds to the connection hole of the base 61 of the rear bracket 6. After the rear bracket 6 is placed on the first support plate 4 and the second support plate 5, since the connection holes of the base are located at the four corners of the base, the positions of the connection holes will correspond to the first support plate 4 and the second support plate 5. By providing the groove 7, it is convenient to drill or expand the connection holes of the base.

[0025] The first support plate 4 and the second support plate 5 are arranged perpendicular to the bottom plate 1 .

[0026] The top of the connecting block 2 is higher than the top of the first support plate 4 and the second support plate 5, and the top of the connecting block 2 is higher than the top of the first support plate 4 and the second support plate 5. After the rear bracket is placed above the first support plate 4 and the second support plate 5, the side of the base 61 contacts the side of the connecting block 2 to achieve the positioning of the rear bracket.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
