[0002] With the development of society and the advancement of science and technology, cars have become an indispensable means of transportation in people's daily lives. The leaf spring in the car is composed of a group of alloy spring steels of unequal lengths, which are similar to spring beams of equal strength, and play a buffering and guiding role in the suspension system. The fixing of the leaf spring requires the use of a leaf spring fixing bracket. The prior art CN213892089U discloses a leaf spring fixing bracket, in which one of the shaft holes in the leaf spring fixing bracket is provided with a cross hole, that is, the shaft hole is provided with a through hole orthogonal to the axis of the shaft hole, and both ends of the through hole need to be countersunk. The traditional countersunk device can only perform countersunk processing on one end of the hole. When the other end of the hole needs to be countersunk, the workpiece needs to be removed from the countersunk device, clamped and fixed in another countersunk device, and then the other end face is countersunk. In this way, two sets of countersunk devices are needed to countersunk a workpiece, and clamping is performed twice, which not only increases the cost of the enterprise, but also reduces the work efficiency and increases the labor intensity of the workers. Utility Model Content

[0003] The utility model aims to provide a flip-type countersinking device to address the deficiencies of the prior art. The device has a reasonable design and is easy to use. After the workpiece is clamped and one end of the hole is countersunk, the workpiece is flipped 180 degrees and then the other end of the hole is countersunk. Both ends of the hole can be countersunk in one clamping, thereby reducing production costs and improving work efficiency.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a flip-type countersinking device, including a frame and a rotating disk, the axis of the rotating disk is horizontally arranged, the rotating disk is provided with a rotating shaft and a driving device for driving the rotating disk to rotate, the rotating shaft is rotatably connected to the frame, the outer surface of the rotating disk is provided with a plurality of groups of positioning columns and fixing columns, the axes of the fixing columns and the rotating shaft are parallel to each other and are located in the same plane, and the end of the fixing column is provided with a clamping device.

[0005] Furthermore, a plurality of groups of the positioning columns and the fixing columns are evenly distributed on both sides of the rotating shaft.

[0006] Furthermore, the frame is provided with an annular slide rail, and the rotating disk is slidably connected to the annular slide rail.

[0007] Furthermore, at least one first fixing hole is provided on the edge of the rotating disk, and second fixing holes are provided on both sides of the annular slide rail, and the axes of the two second fixing holes and the axis of the rotating shaft are located in the same plane.

[0008] Furthermore, the clamping device includes a clamping block, a screw rod and a locking nut. The screw rod passes through the clamping block and is connected to the fixing column. The locking nut is threadedly connected to the end of the screw rod.

[0009] Furthermore, the rotating disk is coaxial with the rotating shaft.

[0010] The beneficial effect of the utility model is that the utility model can realize the locking and fixing of multiple leaf spring fixing brackets by arranging several groups of positioning columns and fixing columns on the surface of the rotating disk, and then the countersinking tool performs countersinking processing on one end of the through hole with a vertical axis. After the processing is completed, the driving device drives the rotating disk to rotate 180 degrees, and the other end of the through hole to be countersunk of the workpiece is turned over to the top to perform countersinking processing on the other end of the through hole. The utility model can clamp and fix multiple workpieces, and simultaneously perform countersinking processing on both ends of the through holes of multiple workpieces, thereby improving work efficiency and reducing production costs.

When the aperture diameters of the two axial holes of the leaf spring fixing bracket are unequal, the fixing column 6 is a stepped shaft. When the aperture diameter of the axial hole at the end away from the rotating disk 2 is larger, the end of the fixing column 6 is sleeved with a sleeve matching the axial hole, which is beneficial to ensure that the axis of the hole to be leveled is vertical after fixation; the axes of the fixing column 6 and the rotating shaft 3 are parallel to each other and are located in the same plane, and the end of the fixing column 6 is provided with a clamping device 7.

[0020] During operation, the fixing column 6 passes through the coaxial axial hole of the leaf spring fixing bracket, and the positioning column 5 passes through the through hole in the base of the leaf spring fixing bracket. The positioning column and the fixing column 6 are used to realize the positioning of the leaf spring fixing bracket, and then the outer end of one of the axial holes is pressed by the clamping device 7, and a force is applied to the leaf spring fixing bracket in the direction of the rotating disk 2, so that the leaf spring fixing bracket is fixed and pressed, and the axis of the through hole to be countersunk of the leaf spring fixing bracket fixed on the rotating disk 2 is vertical; when countersinking, the countersinking tool first countersinks one end of the hole. After completion, the driving device 4 drives the rotating disk 2 to rotate 180° so that the other end of the through hole to be countersunk is flipped to the top, which is convenient for countersinking the other end of the through hole.

[0021] Several groups of the positioning columns 5 and the fixing columns 6 are evenly distributed on both sides of the rotating shaft 3. Preferably, 2 or 4 groups of the positioning columns 5 and the fixing columns 6 are provided, and then 1 or 2 groups of the positioning columns 5 and the fixing columns 6 are distributed on both sides of the rotating shaft 3, respectively, so as to balance the two ends of the rotating shaft 3 and facilitate the driving device 4 to drive the rotating disk 2 to rotate.

[0022] The frame 1 is provided with an annular slide rail 11, and the rotating disk 2 is slidably connected to the annular slide rail 11; at least one first fixing hole 21 is provided on the edge of the rotating disk 2, and second fixing holes 111 are provided on both sides of the annular slide rail 11, and the axes of the two second fixing holes 111 are located in the same plane as the axis of the rotating shaft 3. When countersinking one end of the through hole, the latch passes through the first fixing hole 21 and the second fixing hole 111 to lock the rotating disk 2, which is convenient for the countersinking tool to countersink one end of the through hole; when countersinking the other end, the latch is removed, and the driving device 4 drives the rotating disk 2 to rotate 180°, and then the latch passes through the first fixing hole 21 and the second fixing hole 111 to lock the rotating disk 2, which is convenient for countersinking processing.
