According to an aspect of the application, be connected with one on the assembly end and prevent changeing the bolt, prevent changeing the bolt with the stopper contact to make through preventing changeing the bolt and supporting tightly the stopper.
With this kind of mode, through the mode that will prevent changeing bolted connection at the main part outer wall with it support tight stopper for the stopper is more stable, has further promoted the top stability of assembly.
According to another aspect of the application, the angle of taper of the horn receiving opening is α, wherein α =40 °.
With this kind of mode above-mentioned, wherein the determination of taper angle is through getting in practice many times, if this taper angle is less than 20 can influence taper fit's compactness for stability is not enough, and can be difficult when processing completion dismantlement after being greater than 40 degrees, so this application has selected 40 that the degree of adaptability is moderate with the dismantlement degree of difficulty as the taper angle of its horn mouth.
According to one aspect of the application, the base is internally provided with an inner cavity hole, a piston and a gland are arranged in the inner cavity hole, the piston is connected in the inner cavity hole in a sealing mode, the gland is connected to the base and blocks the piston, a hydraulic gap is reserved between the piston and the gland, and the hydraulic gap is communicated with an oil inlet and outlet channel, so that the piston can move in the inner cavity hole along the axial direction to push the assembling tip.
Above this kind of mode for after processing is accomplished, drive the piston through hydraulic mode and remove, the piston removes and can contact and exert thrust with the jam of stopper one side, and prevents changeing the bolt and make the stopper can only follow axial displacement, promotes top removal from this and releases the work piece, makes it more convenient to take out the work piece.
According to another aspect of the present application, a positioning post is further disposed between the piston and the gland.
In the above way, the assembly can be referred to the above way, and the guide function of the piston movement can be realized.
