Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
The marks in the figure: 1. the quick-change pressing head comprises a pressing head fixing seat, a quick-change pressing head, a wrench bolt, a mounting hole, a positioning groove, a sliding groove, a bolt head, a positioning ring and a positioning ring.
Detailed Description
The utility model is described in further detail below with reference to the drawings and examples, which are not intended to be limiting.
Referring to the drawings, the quick-change pressure head device comprises a pressure head fixing seat 1, a quick-change pressure head 2 and a spanner bolt 3. The press head fixing seat 1 is fixed on the press machine by bolts, and a mounting hole 4 for mounting the quick-change press head 2 is formed in the center of the press head fixing seat 1. One end of the quick-change pressure head 2 is a connecting end, the connecting end is installed in the installation hole 4, a circle of positioning groove 5 is arranged on the circumferential surface of the connecting end along the circumferential direction, a sliding groove 6 extending along the axial direction is arranged between the positioning groove 5 and the end surface of the connecting end, one end of the sliding groove 6 is communicated with the positioning groove 5, and the other end of the sliding groove is opened on the end surface of the connecting end. The side of pressure head fixing base 1 still is provided with a screw hole, and the screw hole is the through-hole, spanner bolt 3 one end is equipped with the screw thread section, and the tip of bolt section is bolt head 7, and the spanner is installed to the other end, and spanner bolt 3 threaded connection is in the screw hole.
When the quick-change pressure head 2 needs to be installed in the installation hole 4 of the pressure head fixing seat 1, firstly, the sliding groove 6 at the connecting end is aligned with the bolt head 7 of the spanner bolt 3, the quick-change pressure head 2 is pushed into the installation hole 4 from bottom to top, the bolt head 7 of the spanner bolt 3 enters the positioning groove 5 through the sliding groove 6, then the quick-change pressure head 2 is rotated by a certain angle, generally by 90 degrees, and finally the spanner bolt 3 is rotated, so that the bolt head 7 of the spanner bolt 3 is propped against the positioning groove 5 of the quick-change pressure head 2 (generally by 90 degrees of wrench rotation), and locking of the quick-change pressure head 2 is realized, so that the quick-change pressure head 2 is prevented from rotating during bearing press-mounting. When the quick-change pressure head 2 needs to be replaced, the spanner bolt 3 is reversely rotated, the locking of the quick-change pressure head 2 is released, the quick-change pressure head 2 is reversely rotated again, the bolt head 7 of the spanner bolt 3 is aligned with the sliding groove 6, and finally the quick-change pressure head 2 is pulled downwards, so that the quick-change pressure head 2 can be taken down.
In order to ensure that the quick-change pressure head 2 is inserted into the pressure head mounting seat 1 and is inserted into place quickly and once, a circle of positioning ring 8 is arranged on the quick-change pressure head 2, when the quick-change pressure head 2 is inserted, the upper end face of the positioning ring 8 props against the lower end face of the pressure head mounting seat 1 to indicate that the quick-change pressure head 2 is mounted in place, and the rotation of the quick-change pressure head 2 and the locking of the spanner bolt 3 can be carried out in the next step.
In the embodiment, a spanner bolt is used as a locking and positioning piece and used for locking the quick-change pressure head. In other embodiments, other forms of locking and positioning members may be used, such as a locking pin sleeved with a spring, the locking pin is pulled outwards to compress the spring, the inner end of the locking pin is retracted, the quick-change press head can be assembled or taken out at this time, when the quick-change press head is assembled and rotated at a certain angle, the locking pin can be released, the spring is reset, and the locking pin is pressed on the quick-change press head by using the elastic force of the spring. When adopting this kind of structure, the spring assembly is in the pinhole of pressure head fixing base side to the spring needs to have enough elasticity to compress tightly quick change pressure head, therefore comparatively laborious when outwards pulling the locking pin, but this structure still can realize the locking location to quick change pressure head.
Or the spanner of the spanner bolt is replaced by a hand wheel, and the hand wheel is rotated to realize the advance and retreat of the bolt.
Alternatively, the positioning ring 8 on the quick-change ram 2 may be replaced by a plurality of positioning blocks, where the plurality of positioning blocks are located at axial positions of the positioning ring, so as to quickly determine the installation position of the quick-change ram.
The above embodiments are only for illustrating the technical solution of the present utility model and not for limiting it, and it should be understood by those skilled in the art that modifications and equivalents may be made to the specific embodiments of the present utility model with reference to the above embodiments, and any modifications and equivalents not departing from the spirit and scope of the present utility model are within the scope of the claims appended hereto.
