A screw one is arranged on the surface of the pressing plate, and the positioning component for product positioning is arranged at the upper end of the pressing plate. The positioning component includes a support pin, a screw two, a part, and a soft jaw. A screw two is arranged at the upper end of the support pin, and a part is arranged inside the support pin. A soft jaw is arranged on the side of the part.

[0007] Further, three support pins are arranged in a circular distribution about the center point of the pressing plate, and the support pins and the soft jaws are arranged at intervals.

[0008] Further, a fixing groove is arranged on the surface of the soft jaw, and a screw three is arranged inside the fixing groove.

[0009] Further, a machine tool hydraulic chuck is arranged at the lower end of the pressing plate, and an adjustment groove is arranged on the side of the machine tool hydraulic chuck.

[0010] Further, mounting holes are arranged on the surface of the adjustment groove, and hydraulic rods are arranged inside the mounting holes.

[0011] Further, the output end of the hydraulic rod is connected with a control component for adjustment, and the number of the control components is three groups.

[0012] Further, the control component includes a movable frame and a mounting pad, and a mounting pad is installed at the upper end of the movable frame.

[0013] Furthermore, the movable frame and the movable frame are slidably connected, and the shape of the movable frame is an I-shape.

[0014] The utility model provides a split positioning tool for a cam ring product, which has the following beneficial effects:

[0015] 1. The utility model uses three groups of soft claws to perform axial positioning of the cam ring product under the action of the hydraulic rod. The positioning is accurate and stable. When the tooling wear affects the accuracy, the support pins can be installed on the pressure plate according to the processing requirements under the action of screw two, and the cam ring product can be split-positioned in cooperation with the soft claws to achieve the repair of positioning accuracy. When replacing the soft claws, the screw three can be removed to meet the clamping requirements of the same family of cam ring products.

[0016] 2. The utility model uses the adjustment groove to control the installation of the assembly. The interior of the installation hole is used for the installation of the hydraulic rod and also serves to limit the movable frame, thereby increasing the stability of the clamping positioning. The installation pad is used for the installation and fixation of the soft claw. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1 and Figure 3As shown in the figure, a split positioning tooling for a cam ring product includes a pressing plate 1 and a positioning component 3. A first screw 2 is provided on the surface of the pressing plate 1. The positioning component 3 for product positioning is arranged at the upper end of the pressing plate 1, and the positioning component 3 includes a support pin 301, a second screw 302, a part 303, and a soft jaw 304. A second screw 302 is provided at the upper end of the support pin 301. When the tooling wears and affects the accuracy, the support pin 301 can be installed on the pressing plate 1 according to the processing requirements under the action of the second screw 302. A part 303 is arranged inside the support pin 301, and a soft jaw 304 is arranged on the side of the part 303.
