Abstract
Provided is an apparatus for preventing false pressing for supporting member comprising hoodles filled in the positioning pin, the hoodles being supported by a spring installed inside the positioning pin with part being exposed out of the positioning pin, the diameter of the positioning pin being smaller than the internal diameter of the hole of a first supporting member and the internal diameter of the hole of the second supporting member, the equivalent diameter of the part of the positioning pin which is filled with hoodles being larger than the internal diameter of the hole of the first supporting member but being smaller than the internal diameter of the hole of the second supporting member.
Description
Technical field
The utility model relates to a kind of mistake proofing pressure device.
Background technology
Press-fit two supporting members on a kind of connecting rod, the situation that on automatic assembly line, makes a mistake easily and assemble, for example supporting member A, B external diameter are identical, (supporting member A internal diameter is 12mm to the only poor 2mm of internal diameter, supporting member B internal diameter is 14mm), the alignment pin diameter of supporting member A is 11.5mm, and the alignment pin of supporting member A can be put among the supporting member B easily, is press-fited alignment pin so have no idea to control supporting member B (internal diameter 14mm) by mistake.
The utility model content
The object of the present invention is to provide a kind of mistake proofing pressure device that is used for supporting member.
For realizing the mistake proofing pressure device that is used for supporting member of described purpose, be characterized in, comprise the hoodle of can in alignment pin, this hoodle is replaced by the spring that is installed in this alignment pin, and the part exposes to this alignment pin, the diameter of this alignment pin is less than the internal diameter in the hole of the internal diameter in the hole of first supporting member and second supporting member, and the equivalent diameter of the part that is filled with this hoodle of this alignment pin is greater than the internal diameter in the hole of first supporting member but less than the hole internal diameter of second supporting member.
The described mistake proofing pressure device that is used for supporting member, its further characteristics be, is filled with two described hoodles in this alignment pin, and described spring is compressed between two these hoodles.
The described mistake proofing pressure device that is used for supporting member, its further characteristics are, also comprise the Laser emission detector, assembly station at the alignment pin and first supporting member, the light path of this Laser emission detector is positioned at the below of this hoodle, and this Laser emission detector is coupled to the equipment that this alignment pin and first supporting member are installed.
The described mistake proofing pressure device that is used for supporting member, its further characteristics be, is provided with plane mirror between the reflector of Laser emission detector and its configuration, formed to be positioned at two light paths under the described hoodle.
The beneficial effects of the utility model are: because the equivalent diameter of the part that is filled with this hoodle of this alignment pin is greater than the internal diameter in the hole of first supporting member but less than the hole internal diameter of second supporting member, can't fall when being enclosed within first supporting member on the alignment pin, when being enclosed within on the alignment pin, second supporting member will fall, if adopting sniffer such as Laser emission detector or additive method surveys this, therefore, first supporting member and the automatic difference of second supporting member can be come, when on hoodle, applying external force, can be with in the hoodle compression and back alignment pin, guarantee that alignment pin is press fit in the hole of first supporting member, thereby prevent misloading effectively.
Description of drawings
Fig. 1 is the structural map of the alignment pin of band hoodle.
Fig. 2 is the schematic diagram that alignment pin is inserted into first supporting member.
Fig. 3 is the schematic diagram that alignment pin is inserted into second supporting member.
Fig. 4 is the fundamental diagram of Laser Detecting Set.
The specific embodiment
As shown in Figures 2 and 3, first supporting member 21 is identical or close with second supporting member, 22 external diameters, and the internal diameter in the hole 210 of first supporting member 21 is 12mm, and the internal diameter in the hole 220 of second supporting member 22 is 14mm.The diameter R2 of alignment pin 10 is 11.5mm, and alignment pin 10 is press fit in first supporting member 21, is used for first supporting member 21 is positioned.
As shown in Figure 1, in order to prevent misloading, be filled with hoodle 11 in the alignment pin 10, the quantity of hoodle 11 is at least one, among the embodiment shown in the figure be two, hoodle 11 is by the spring 12 outside bias voltages that are arranged in the alignment pin 10, the outside that alignment pin 10 is exposed in hoodle 11 parts, with two hoodles 11 is example, because the outside at alignment pin 10 is exposed in the hoodle part, be equivalent to increase the external diameter of alignment pin 10, if the distance in the cross section of definition alignment pin 10 (containing hoodle 11) farthest 2 is equivalent diameter R1, then R1 is greater than R2.
As shown in Figure 2, though the diameter R2 of alignment pin 10 is 11.5mm, less than the internal diameter 12mm of first supporting member 21, first supporting member 21 is enclosed within on the alignment pin 10 by means of its hole 210, and first supporting member 21 will supported by hoodle, can not fall.
As shown in Figure 3, because the internal diameter in the hole 220 of second supporting member 22 is much larger than the diameter of alignment pin 10, even and hoodle 11 outer being exposed at outside the alignment pin 10, the equivalent diameter of alignment pin 10 is also less than the internal diameter in hole 220, therefore, when second supporting member 22 is enclosed within on the alignment pin 10, second supporting member 22 will fall.
As shown in Figure 4, go up installation Laser emission detector 30 at workbench (showing in the drawings), mounting plane reflective mirror between Laser emission detector 30 and reflector 32, a light beam is become two, the light path of Laser emission detector 30 is through the below of the hoodle 11 of alignment pin 10, like this, whether Laser emission detector 30 just can detect the supporting member 21 or 22 that is enclosed within on the alignment pin 10 and fall, Laser emission detector 30 and press-fit alignment pin, the devices, coupled of supporting member, when detecting supporting member and fall, this equipment is by locked, can't start, when detecting supporting member and do not fall, this equipment can start, thereby has played the generation that prevents wrong installation situation effectively.
