Abstract

The utility model discloses a macro-porous positioning and locking device. The macro-porous positioning and locking device comprises a connecting base, a cylinder fixedly arranged at the bottom of the connecting base, a support plate fixedly arranged on the top of the connecting base, a base fixedly arranged in the center of the upper portion of the support plate, and positioning blocks which are arranged on both sides of the base respectively and are fixedly connected with the support plate, wherein a through hole is formed in the center of the base; two intersecting pressure arms are arranged in the through hole, and are hinged to the base through the same rotating shaft; the lower ends of the pressure arms are in transmission connection with the cylinder respectively through pull rods; the upper ends of the pressure arms can be pressed against corresponding positioning blocks respectively. A macro-porous positioning mechanism is simple in structure and skillful in design, and positioning and locking at macro-porous positions are realized. Meanwhile, both sides of the two pressure arms are positioned simultaneously, thereby ensuring the stability of positioning at the macro-porous positions, effectively avoiding deformation at the macro-porous positions, and bringing convenience to subsequent machining and detection.

Description

Macropore positioning and locking device

Technical field

The utility model relates to Machining Technology field, particularly relates to a kind of macropore positioning and locking device.

Background technology

Machining as auto manufacturing in, automobile component needs to process before dispatching from the factory, the detection of assembling and Performance Detection or machining accuracy, when processing or detection, automobile component need to be fixed on checkout gear, on automobile component, there are a lot of feature holes, and on checkout gear, also there is the alignment pin corresponding with feature holes position on automobile component to be detected, after parts to be assembled or detection automobile component are in place, utilize the cooperation of alignment pin and locating hole that various operations are carried out in automobile component location then.

But, in real work, because each feature holes position size shape is different, especially while processing or detect for macropore periphery, if can not be accurate and locate and lock and will impact follow-up in macropore place, so with regard to a kind of fixture that can position to parts macropore place locking of needs.

Utility model content

The purpose of this utility model is for the technological deficiency existing in prior art, and provide a kind of simple in structure and can realize simultaneously location and locking macropore positioning and locking device.

For realizing the technical scheme that the purpose of this utility model adopts be:

A kind of macropore positioning and locking device, comprise Connection Block, be fixedly installed the cylinder of described Connection Block bottom, be fixedly installed on the gripper shoe at described Connection Block top, be fixedly installed on the pedestal at gripper shoe central upper portion place, and the locating piece that is separately positioned on pedestal both sides and is fixedly connected with described gripper shoe, wherein, described pedestal center offers through hole, in described through hole, be provided with two pressure arms that are crisscross arranged, two described pressure arms with rotating shaft with the described hinged setting of pedestal, described pressure arm lower end is connected with described cylinder-driven through pull bar respectively, the upper end of described pressure arm can be pressed in respectively on the locating piece of respective side.

Described locating piece is L shaped structure.

Described end, pressure arm upper end is fixedly installed briquetting with enlarge active surface.

Compared with prior art, the beneficial effects of the utility model are:

Large hole locating device of the present utility model design simple in structure is ingenious, visual operating mode is located at the position of any needs, in location, front air cylinder is regained piston rod, now pressure arm is gathering state, it can not be inserted in and form impact macropore, when the edge of macropore is positioned behind piece upper surface location, at this moment drive the piston rod of cylinder to stretch out, under the effect of pull bar, two pressure arms are depressed respectively also and the EDGE CONTACT of macropore compression, realize location and the locking at macropore place, two pressure arms are located both sides respectively simultaneously simultaneously, also guaranteed the stationarity of location, macropore place, effectively avoid macropore place that deformation occurs, for following process or detection facilitate.

Accompanying drawing explanation

Figure 1 shows that macropore positioning and locking device perspective view of the present utility model;

Figure 2 shows that the internal structure schematic diagram shown in Fig. 1.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As depicted in figs. 1 and 2, macropore positioning and locking device of the present utility model comprises Connection Block 1, be fixedly installed the cylinder 2 of described Connection Block bottom, be fixedly installed on the gripper shoe 3 at described Connection Block top, be fixedly installed on the pedestal 4 at gripper shoe central upper portion place, and two locating pieces 5 that are separately positioned on pedestal both sides and are fixedly connected with described gripper shoe, wherein, described pedestal center offers through hole, in described through hole, be provided with two pressure arms that are crisscross arranged 6, two pressure arms with rotating shaft with the described hinged setting of pedestal, described pressure arm lower end is connected with described cylinder-driven through pull bar 7 respectively, the upper end of described pressure arm can be pressed in respectively on the upper surface of locating piece of respective side.Wherein, described pressure arm is L shaped or arcuate structure or other arbitrary structures, with can be in the time that rotating shaft rotates its end, upper end can and locating piece interfere and be advisable.Described Connection Block is preferably L shaped, its vertical plate can be fixedly connected with miscellaneous part, described cylinder is fixed on the level board below of L shaped Connection Block, described gripper shoe be arranged in parallel with described L shaped Connection Block level board and is fixedly connected with the vertical plate top of L two Connection Blocks, utilize the design of L shaped Connection Block can increase the distance of pedestal and cylinder, improve the smoothness of pressure arm and backward stick action, guarantee the stationarity of fixture overall operation.Specifically, arranging of described rotating shaft adopts both sides, pedestal front and back to be respectively arranged with U-lag 11, the end of described rotating shaft 12 is embedded in described U-lag, and the orifice plate being fixedly connected with described pedestal is confined in U-lag rotating shaft to realize the location of rotating shaft.

Large hole locating device of the present utility model design simple in structure is ingenious, visual operating mode is located at the position of any needs, in location, front air cylinder is regained piston rod, now pressure arm is gathering state, it can not be inserted in and form impact macropore, when the edge of macropore is positioned behind piece upper surface location, at this moment drive the piston rod of cylinder to stretch out, under the effect of pull bar, two pressure arms are depressed respectively also and the EDGE CONTACT of macropore compression, the location and the locking that realize macropore place synchronously completing, for following process or detection facilitate.

Further, for avoiding the excessive macropore edge that causes of pressure arm local pressure to occur impression, described end, pressure arm upper end is fixedly installed briquetting with enlarge active surface.

The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
