Description

A kind of self-centering auxiliary clamping device
Technical field
The present invention relates to the machining apparatus field of precision castings, it is particularly suitable for being not easy to feel relieved, structure is complicated, not easy to control The stationary positioned of the blank precision castings of part rotation direction etc, specially a kind of self-centering auxiliary clamping device.
Background technique
Traditional centring means lean on fixed structure, cannot change with blank itself adjustment, motion mode it is single, can only be simple Ground translation or rotation, and the pressing force compressed often has big difference, and compressing point at this time possibly can not be placed on accurate position On, the geometric center of part positioning surface is deviated from, the working position relative displacement of part, accurate to dimension is easy to cause to become Difference, What is more there is part shaking in process, and fall off separation, eventually leads to part rejection and threatens personal safety.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of self-centering auxiliary clamping devices, and realization can be facilitated steady Fixed reliable clamping, guarantees processing quality.
Its technical solution is such that a kind of self-centering auxiliary clamping device comprising bottom plate is provided on the bottom plate Positioning mechanism and clamp system, which is characterized in that the positioning mechanism includes vertical positioning pin and horizontal location pin, the clamping Mechanism includes the vertical plate for surrounding rectangular cavities, offers guide groove on the vertical plate of transverse ends respectively and is equipped with lateral push away Plate also has guide groove on the vertical plate at longitudinal both ends and is equipped with longitudinal push plate, the transverse direction push plate and described vertical Be respectively arranged with hold-down head to push plate medial surface, lateral surface is inclined-plane, installation with the transverse direction there are two pushing away on the vertical plate The laterally wedge-shaped pushing block of the inclined-plane cooperation of plate, two longitudinal wedge-shaped pushing blocks with the inclined-plane cooperation of longitudinal push plate, two institutes It states laterally wedge-shaped pushing block and passes through lateral pressure plate connection, two longitudinal wedge-shaped pushing blocks pass through longitudinal pressure plate connection, described Lateral pressure plate and longitudinal pressure plate are installed on the vertical plate by being set with the lock-screw of first back-moving spring respectively, It is separately installed with link block in the transverse direction push plate and longitudinal push plate, passes through second between the link block and the vertical plate Reset spring connection.
It is further characterized by the vertical positioning pin is located on the bottom plate among the rectangular cavities, the level Positioning pin is through the vertical plate and is provided with latch segment;
Between longitudinal wedge-shaped pushing block and longitudinal pressure plate, the laterally wedge-shaped pushing block and the lateral pressure plate Between pass through split pin connection.
Using structure of the invention, part, which is put, realizes positioning by vertical positioning pin and horizontal location pin, due to longitudinal wedge The inclined-plane cooperation of shape pushing block and longitudinal push plate, laterally wedge-shaped pushing block and the inclined-plane of lateral push plate cooperate, and lock-screw rotation pushes When longitudinal pressure plate and lateral pressure plate move inward, drive two lateral push plates simultaneously to part it is mobile realize horizontal clamping, Two longitudinal push plates realize that longitudinal direction clamps to part is mobile simultaneously, and both lateral sides clamping force is identical, and longitudinal two sides clamping force is identical, It is clamped from four direction, realizes reliable and stable clamping, avoid phenomena such as deviating in the prior art, ensure that processing quality.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention;
Fig. 2 is sectional view along A-A in Fig. 1;
Fig. 3 is B-B direction cross-sectional view in Fig. 1.
Specific embodiment
See Fig. 1, Fig. 2, shown in Fig. 3, a kind of self-centering auxiliary clamping device comprising bottom plate 1, it is fixed to be provided on bottom plate 1 Position mechanism and clamp system, positioning mechanism include vertical positioning pin 2 and horizontal location pin 3, and clamp system includes surrounding rectangular cavity The vertical plate 4 of body offers guide groove on the vertical plate 4-1 of transverse ends respectively and is equipped with lateral push plate 5, the vertical plate at longitudinal both ends Also guide groove is had on 4-2 and longitudinal push plate 6 is installed, and lateral push plate 5 is respectively arranged with pressure with longitudinal 6 medial surface of push plate Tight head 7, lateral surface are inclined-plane, and there are two the laterally wedge-shaped pushing blocks 8, two cooperated with the inclined-plane of lateral push plate 5 for installation on vertical plate 4 Longitudinal wedge-shaped pushing block 9 that a inclined-plane with longitudinal push plate 6 cooperates, two lateral wedge-shaped pushing blocks 8 pass through lateral pressure plate 10 and connect, Two longitudinal wedge-shaped pushing blocks 9 pass through longitudinal pressure plate 11 and connect, and lateral pressure plate 10 passes through suit with longitudinal pressure plate 11 respectively There is the lock-screw 13 of first back-moving spring 12 to be installed on vertical plate 4, is separately installed with and connect in lateral push plate 5 and longitudinal push plate 6 Block 14 is connected between link block 14 and vertical plate 4 by second back-moving spring 15, in order to guarantee reset effect, with a guiding spiral shell Nail 19 passes through link block 14 and second back-moving spring 15 and is fixedly connected with vertical plate 4, slides between link block 14 and guider screw 19 Cooperation.Vertical positioning pin 2 is located on the bottom plate 1 among rectangular cavities, and horizontal location pin 3 is through vertical plate 4 and is provided with latch segment 16, realize the horizontal and vertical positioning of part 17;Between longitudinal wedge shape pushing block 9 and longitudinal pressure plate 11, lateral wedge-shaped pushing block 8 It is connect by split pin 18 between lateral pressure plate 10, can there is some moderate fluctuations, it is ensured that both lateral sides and longitudinal two sides Compression.
