The technical scheme is further defined, and the base is structured as follows: the support seat is arranged on the back of the bottom plate, the bottom plate is arranged in an inclined mode through the support seat, and upright posts are outwards protruded on the support surface of the bottom plate.
The technical scheme is further improved, and the supporting seat is provided with a fixing hole.
The technical scheme is further limited, the positioning piece and the guiding piece are formed by bending steel plates, the positioning block is fixedly connected with the upright post, a space is reserved between the bottom of the positioning block and the bottom plate, the guiding piece is fixed on the bottom plate, and a positioning groove cavity on the positioning piece and a guiding groove cavity on the guiding piece are oppositely arranged;
the technical scheme is further improved, and the base is provided with a handle.
The technical scheme is further defined that the inclination of the inclined plane on the base is 15-25 degrees.
The beneficial effects are that: according to the invention, the assembly cutting-in angle among the sliding block seat, the balance pressure spring and the cam sliding block is changed through the inclined plane on the base, so that the assembly operation can be rapidly completed, the working efficiency is improved, and the production cost is reduced; the invention has simple integral structure, low manufacturing cost, light weight and convenient taking by operators.

Description of the embodiments
As shown in fig. 2, the cam system assembling tool comprises a base 5, wherein a positioning piece 6 and a guiding piece 7 are arranged on the inclined surface of the base; during assembly, the positioning piece on the base is used for positioning the sliding block seat and the balance pressure spring assembly, the inclined plane on the base is used for adjusting the assembly cutting angle between the sliding block seat, the balance pressure spring and the cam sliding block, and the guide piece is used for guiding the elastic limiting block on the cam sliding block to the position which is in limiting fit with the sliding block seat;
as shown in fig. 2, the base 5 has a structure: the bottom plate comprises a bottom plate 501, wherein a supporting seat 502 is arranged on the back surface of the bottom plate, the bottom plate is obliquely arranged through the supporting seat, and an upright post 503 is outwards protruded on the supporting surface of the bottom plate; the structure is simple, the manufacturing cost is low, and the weight is light;
as shown in fig. 2, the supporting seat is provided with a fixing hole 504, and the supporting seat is fixedly connected with the workbench through a bolt in the fixing hole, so that the problem of displacement of the supporting seat during assembly is prevented;
as shown in fig. 2, the positioning piece 6 and the guiding piece 7 are formed by bending steel plates, the positioning block is fixedly connected with the upright post, a space is reserved between the bottom of the positioning block and the bottom plate, the reserved space is used for preventing the elastic limiting block from interfering with the bottom plate in the press mounting process, the guiding piece is fixed on the bottom plate, and the positioning groove cavity on the positioning piece and the guiding groove cavity on the guiding piece are oppositely arranged; the structure is simple, the manufacturing cost is low, and the weight is light;
