Detailed Description
The invention will be further described with reference to the following examples and figures 1 to 5.
The utility model provides a split type bearing excircle location quick change frock, is applicable to the bearing location frock on the intelligent manufacturing assembly line, as shown in figure 1, including frock clamp plate 1, frock dead lever 2, frock transition pressure head 3, quick change location overcoat 4 and upper spring 5 and lower spring 6. The tool pressing plate 1 is installed above the tool fixing rod 2, the tool pressing plate 1 is fixedly connected with the tool fixing rod 2 through a fixing bolt 9, and the diameter of the tool pressing plate 1 is larger than that of the tool fixing rod 2. The tool fixing rod 2 is used for penetrating through the equipment positioning pressure plate 10 and can move up and down relative to the equipment positioning pressure plate 10, the tool transition pressure head 3 is detachably and fixedly connected with the lower thick rod, the tool transition pressure head and the lower thick rod are connected through a fastening jackscrew 8, the quick-change positioning outer sleeve 4 is sleeved on the tool transition pressure head 3, and the tool transition pressure head 3 can move up and down relative to the quick-change positioning outer sleeve 4; the tool fixing rod 2 is composed of an upper thin rod and a lower thick rod which are fixedly connected, and the upper thin rod and the lower thick rod are of an integrated structure. The upper spring 5 is sleeved on the upper thin rod, one end of the upper spring 5 is abutted to the tool pressing plate 1, and the other end of the upper spring is abutted to the equipment positioning pressing plate 10.
The lower thick rod is provided with a limiting part, the tool fixing rod 2 penetrates through the mounting hole in the equipment positioning pressing plate 10 and is arranged on the equipment positioning pressing plate 10, the diameter of the limiting part is larger than that of the mounting hole, and therefore the tool fixing rod 2 can only move up and down in the mounting hole through the upper thin rod part. The lower spring 6 is sleeved on the lower thick rod, one end of the lower spring 6 is abutted to the limiting part, and the other end of the lower spring is abutted to the quick-change positioning outer sleeve 4.
The end of the lower thick rod is provided with an inward concave mounting groove for mounting the tool transition pressure head 3. The depth of the installation groove is smaller than the height of the tooling transition pressure head 3, in other words, only part of the tooling transition pressure head 3 is installed in the installation groove, and the other part of the tooling transition pressure head is positioned in the quick-change positioning outer sleeve 4. The tooling transition pressure head 3 is at least provided with two steps, namely a first step and a second step, the diameter of the circle where the second step is located is larger than that of the circle where the first step is located, the end face of the lower thick rod is abutted against the first step, the quick-change positioning outer sleeve 4 is sleeved on the second step, and the tooling transition pressure head 3 can move up and down in the quick-change positioning outer sleeve 4 under the action of the pressure head of the pressurizing equipment. 6 bearing positioning glass bead screws 7 are uniformly distributed on the quick-change positioning outer sleeve 4, the glass bead screws are internally provided with springs and support external steel beads, the steel beads compress the internal springs when receiving external force and shrink inwards, and 6 bearing positioning glass bead screws are uniformly distributed on the quick-change positioning outer sleeve and used for temporarily fixing the bearings.
