The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As depicted in figs. 1 and 2, the cam stopping means that is used for welding tooling of the present utility model comprises by a base plate 1 and is fixed on
A cam chair 2 and two push rod support 7 common holders that constitute on the base plate 1, cam chair 2 is fixed by bolts on the base plate 1, two push rod supports 7 also are fixed by bolts on the base plate 1, cam 3 is installed in rotation on the cam chair 2, two push rods 4 are slidably mounted in respectively on two push rod supports 7, two push rods 4 lay respectively at the both sides of cam 3, one end of every push rod 4 contacts with the wheel rim of cam 3, the other end of every push rod 4 is provided with confined planes 10, the other end that specifically can be every push rod 4 is by bolting one jacking block 6, confined planes 10 is positioned on the end face of jacking block 6, and an action bars 9 is fixedlyed connected with cam 3 screw threads.
As shown in Figure 6, each push rod support 7 comprises a horizontal push rod carrier base 701 and two sidewalls 702 perpendicular to horizontal push rod carrier base, two sidewalls 702 lay respectively at the two ends of horizontal push rod carrier base 701, each sidewall 702 is provided with push rod bracket holes 703, and push rod 4 passes two push rod bracket holes 703 slidably.
As shown in Figure 1, the top of cam chair 2 also is provided with a upper cover plate 8, and upper cover plate 8 two ends are separately fixed on two push rod supports 7, and upper cover plate 8 is provided with a stopper slot 801 that supplies action bars 9 to pass, as shown in Figure 4.
As shown in Figure 2, push rod 4 is provided with a steady pin 11, be specially push rod 4 and be provided with an installing hole, steady pin 11 insert in the installing holes and with the installing hole interference fit, thereby steady pin 11 and push rod 4 are formed a fixed connection, one spring 5 is enclosed within on the push rod 4, and an end of spring 5 withstands on the steady pin 11, and the other end withstands on the inboard of push rod support 7.
As shown in Figure 5, cam chair 2 is provided with a U type groove 201 that is used to install cam 3, is respectively equipped with a hole 202 on two U-shaped arms of U type groove 201, and cam 3 is provided with a cam hole, and cam shaft 301 passes two seat holes 202 and cam hole.
Figure 7 shows that the assembling schematic diagram of the utility model device on welding tooling.
