The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing the utility model is described in further detail.
As shown in Figure 1, a kind of positioning fixture of welded sleeve, comprise the clamp arm 8 that base with the first cylinder 3, an end and the first cylinder 3 are hinged and be arranged on the base along with the suitable some compact heaps 12 of clamp arm 8.Base comprises that supporting seat 1 and installing plate 2, the first cylinders 3 that are fixed on the supporting seat 1 are fixed on the installing plate 2, and along being provided with compact heap 12, at least one compact heap is provided with alignment pin 11b in the compact heap 12 on the installing plate 2.The side of contiguous the first cylinder 3 is provided with mount pad 5, fitting machine control reversal valve 6 on the mount pad 5 on the installing plate 2.Wherein, machine control reversal valve 6 is roller lever machine control reversal valve.The side of installing plate 2 is provided with guide post 4.As shown in Figure 2, when anchor clamps are in releasing orientation, start the first cylinder 3, the thrust that clamp arm 8 is subject to the first cylinder 3 moves down, for not being offset in the process that clamp arm 8 is rotated, make things convenient for the location of its position, therefore in installing plate 2 sides guide post 4 is set.Installing plate 2 is provided with limited block 9, and clamp arm 8 is provided with the projection suitable with limited block 9.When clamp arm 8 was rotated down compression installing plate 2, projection and the limited block 9 on the installing plate 2 that clamp arm 8 belows arrange were suitable, thereby fixedly positioning clamp arm 8, and it is not offset in the process of clamping and positioning, so that did not cause the coarse problem in location.
On the clamp arm 8 away from hinged the first cylinder 3 places long-pending the second cylinder 10 less than the first cylinder 3 that is fixed as one, be of a size of φ 63-100 such as the first cylinder 3, the second cylinder 10 is square cylinder, is of a size of 30*30, it is the bolted by 4 M8, can adjust up and down.
Referring to Fig. 3, Fig. 3 is the connection pneumatic diagram of the first cylinder 3, the second cylinder 10, shuttle valve 14 and machine control reversal valve 6, and wherein a, b two ends connect source of the gas.The starter motor control the reversal valve 6 but drive rod of the first cylinder 3 rises.
In conjunction with Fig. 1, Fig. 2 and Fig. 3, the workflow of this positioning fixture is as follows:
Compaction process: after the mounting bracket part on the side bar of cabin is put on the alignment pin 11b, press clamp switch, thereby by switch activated gas circuit the first cylinder 3 is opened, when the first cylinder 3 rises, band motivation control valve clamping switch 7 rises and clamp arm 8 rotates, when clamp arm 8 compressing component, and 6 ventilations of machine control valve clamping switch 7 starter motor control reversal valves, drive shuttle valve 14 ventilations, make like this 10 ventilations of the second cylinder open downward compression.
Release process: be to open by master switch when opening, after but gas circuit is reverse, the second cylinder 10 is opened in shuttle valve 14 ventilations, cause the second cylinder 10 to the first cylinders 3 are little, so the second cylinder 10 to the first cylinders 3 are opened first, utilize this point time difference, just can not cause positioning compression pin 11a and part interference when opening.
