Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Fig. 1,2,3,4,5 and 6, a kind of change speed gear box transferring pallet, this pallet is mainly made up of base plate 1, column 2 and change speed gear box positioning compression structure etc. Wherein, described base plate 1 is rectangular steel plates, and its thickness is 2mm. Four edges at base plate 1 are all installed with a root post 2, and the bottom of this column 2 is fixed with base plate 1. The cross section of described column 2 is U-shaped, and two side upper ends of this column 2 have a through U-shaped breach in front and back. It addition, four edges of described base plate 1 lower face are welded with a quarter bend 22 respectively, the head and the tail of these four quarter bends 22 are connected with corresponding described column 2 respectively. The two ends of every quarter bend 22 bottom surface are respectively welded a L-shaped pipe 23, the upper end of this vertical section of L-shaped pipe 23 is welded with quarter bend 22, the termination of every L-shaped pipe 23 horizontal segment is welded and fixed with corresponding column 2, and the bottom surface of every L-shaped pipe 23 horizontal segment is concordant with described column 2 bottom surface.
From Fig. 1,2 and 3 can be seen that, the number of described change speed gear box positioning compression structure is at least two, and these change speed gear box positioning compression structures are located at the upper face of described base plate 1. In the present case, the number of change speed gear box positioning compression structure is eight, and every four change speed gear box positioning compression structure left and right are side-by-side.
Each change speed gear box positioning compression structure is mainly made up of first locating piece the 3, second locating piece 4, locating platform 5, first little positioning vertical column the 6, the 3rd locating piece the 7, second little positioning vertical column 8 and holding down assembly. Wherein, first locating piece the 3, second locating piece 4 and locating platform 5 are arranged in triangle disposition, first locating piece 3 and the second locating piece 4 are arranged side by side, the opposite side of the two locating piece end face is plane, and the end face of the two locating piece is lower than be set forth in locating platform 5 end face, and before and after the top of this locating platform 5, there are two first little positioning vertical columns 6 side by side. Described 3rd locating piece 7 and locating platform 5 set up separately on the both sides of the first locating piece 3,3rd locating piece 7 and the first locating piece 3 are arranged side by side, and the 3rd locating piece 7 identical with the structure of the first locating piece 3, and before and after the top of the 3rd locating piece 7, have two second little positioning vertical columns 8 side by side.
From Fig. 1 to 6 it is also seen that, being provided with one between described second locating piece 4 and locating platform 5 to hold down assembly, this holds down assembly and is mainly made up of connection column 9, adapter sleeve 10, tooth bar 11, fairlead 12, depression bar 13, compact heap 14, gear 15, gear shaft 16, n shape part 17, connecting plate 18, locking rod 19 and guide plate 20. Wherein, the upper face of the lower end and base plate 1 that connect column 9 is fixed, and this connection column 9 is installed with the adapter sleeve 10 of a up/down perforation, and is installed with a toothed rack 11 in this adapter sleeve 10.
The upper end of described tooth bar 11 is horizontally fixed with a fairlead 12, is sliding combined with a depression bar 13 in this fairlead 12. One end of depression bar 13 is for compressing end, and the bottom of this compression end has a "T"-shaped groove 13a. Described compact heap 14 is towards the region between first locating piece the 3, second locating piece 4 and locating platform 5, and this compact heap 14 is T-shaped structure, and the bottom surface of compact heap 14 is for workpiece pressing. Described compact heap 14 top is contained in the "T"-shaped groove 13a of depression bar 13, and spacing by this "T"-shaped groove, and the left end of depression bar 13 is coated with a baffle plate 24, and this baffle plate 24 is used for preventing compact heap 14 from exiting from "T"-shaped groove 13a. Vertically being provided with four compression springs 25 between the bottom land of described compact heap 14 upper surface and "T"-shaped groove 13a, these four compression springs 25 are arranged on four summits of same rectangle.
Described gear 15, after the via on adapter sleeve 10, engages with tooth bar 11, and this gear 15 empty set is on gear shaft 16, and gear shaft 16 is installed in outside adapter sleeve 10. Two sides of described n shape part 17 are hinged with gear shaft 16 two ends respectively, are installed with one piece of connecting plate 18 between the two side. Described locking rod 19 inner traverse n shape part 17 can contact with the profile of tooth of described gear 15 after connecting the via on limit and connecting plate 18, thus the rotation of limiting gear 15. The outer end of described locking rod 19 is bulb end, the inner of this locking rod 19 is installed with one piece of guide plate 20 simultaneously, corresponding with on described 17 two sides of the n shape part respectively bar hole in the two ends of this guide plate 20 is slidably matched, and clamping has a return spring 21 between guide plate 20 and described connecting plate 18, this return spring 21 is sleeved on locking rod 19 simultaneously.
