Description
Technical field
The present invention relates to a kind of for holding down assembly Work-sheet pressing, in order to storage, transporting work pieces.
Background technology
In the industrial production, storage and transhipment are needed after work piece production.At present, it is generally adopted wooden case to pack change speed gear box, is then transported through.Existing mode has the drawback that: 1, transhipment time need dismounting wooden case, in-convenience in use, efficiency low；2, the structural strength of wooden case is poor；3, the cost of wooden case is high.
Summary of the invention
The technical problem to be solved is in that to provide a kind of compact conformation simple, easy to use holding down assembly, and is intended to be held down assembly Work-sheet pressing on base plate by this.
Technical scheme is as follows: one holds down assembly, it is characterized in that: include connecting column (9), compact heap (14), gear (15), n shape part (17) and locking rod (19), the lower end wherein connecting column (9) is installation end, this connection column is installed with the adapter sleeve (10) of a up/down perforation, and in this adapter sleeve, is installed with a toothed rack (11)；Described tooth bar (11) upper end is horizontally fixed with a fairlead (12), this fairlead is sliding combined with a horizontally disposed depression bar (13), the left end of this root 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 T-shaped structure, the bottom surface of this compact heap is used for workpiece pressing, and compact heap (14) top is contained in the "T"-shaped groove (13a) of described depression bar (13), and it is spacing by this "T"-shaped groove, and the left end of depression bar (13) is coated with a baffle plate (22), this baffle plate is used for preventing compact heap (14) from exiting from "T"-shaped groove (13a)；Vertically being provided with four compressions spring (23) between the bottom land of described compact heap (14) upper surface and "T"-shaped groove (13a), these four compressions spring (23) are arranged on four summits of same rectangle；
Described gear (15) is after the via on adapter sleeve (10), engage with described tooth bar (11), this gear empty set is on gear shaft (16), and gear shaft (16) is installed in adapter sleeve (10) outside；Two sides of described n shape part (17) are hinged with gear shaft (16) two ends respectively, one piece of connecting plate (18) it is installed with between the two side, after the inner via connected through n shape part (17) on limit and connecting plate (18) of described locking rod (19), can contact with the profile of tooth of described gear (15), thus the rotation of limiting gear (15)；Described locking rod (19) the inner is installed with one piece of guide plate (20), corresponding with on (17) two sides of the described n shape part respectively bar hole in the two ends of this guide plate is slidably matched, and clamping has a return spring (21) between guide plate (20) and described connecting plate (18), this return spring is sleeved on locking rod (19) simultaneously.
Before employing, first the installation end of middle connection column (9) lower end that originally holds down assembly and one piece of base plate are connected.During use, first workpiece is positioned on base plate, then pulls out locking rod (19), at this moment can move up and down tooth bar (11), thus moving up and down depression bar (13)；When the compact heap (14) on depression bar (13) is adjacent to workpiece end face, decontrol locking rod (19), at this moment locking rod (19) can reset rapidly under the effect of return spring (21), so that the inner of locking rod (19) contacts with the profile of tooth of gear (15), thus can the rotation of limiting gear (15), thus preventing tooth bar (11) from moving up and down, so preliminary by Work-sheet pressing on base plate.Simultaneously, owing to there is gap between the profile of tooth of tooth bar (11), thus not easily very effectively workpiece pressing, at this moment just can very effectively make the end face of compact heap (14) and workpiece be close to by four compressions spring (23), thus effectively further workpiece pressing.
Adopt above technical scheme, the simple in construction that originally holds down assembly, compact, it is easy to implement and easy to use laborsaving, can by tooth bar and compression spring reliably by Work-sheet pressing, thrust is big, thus convenient storage and transporting.
As preferably, the outer end of described locking rod (19) is bulb end, and the inner of this locking rod (19) is tip end.Adopt above structure, the outer end of locking rod (19) is that bulb end is easy to pull out locking rod (19), and the inner of locking rod (19) is tip end, the inner of locking rod (19) thus can be made reliably to contact with the profile of tooth of described gear (15).
Beneficial effect: the simple in construction that originally holds down assembly, compact, it is easy to implement, and easy to use laborsaving, can by tooth bar and compression spring reliably by Work-sheet pressing, and thrust is big, thus convenient storage and transporting.

Fig. 1 is the structural representation of the present invention；
Fig. 2 is the A direction view of Fig. 1；
Fig. 3 is the scheme of installation of compact heap 14 in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, 2, 3, one holds down assembly, and 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, guide plate 20, return spring 21, baffle plate 22 and compression spring 23.Wherein, the lower end connecting column 9 is link, and this link is for being connected with base plate (not shown in FIG.), in order to be arranged on originally holding down assembly on base plate.Connect the adapter sleeve 10 being installed with a up/down perforation on column 9, and in this adapter sleeve 10, be installed with a toothed rack 11.The upper end of described tooth bar 11 is horizontally fixed with a fairlead 12, is sliding combined with a horizontally disposed depression bar 13 in this fairlead 12.The left 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 T-shaped structure, and the bottom surface of this compact heap 14 is used for workpiece pressing, and compact heap 14 top is contained in the "T"-shaped groove 13a of depression bar 13, and spacing by this "T"-shaped groove.Further, the left end of depression bar 13 is fixed with a baffle plate 22 by screw, and the left side of depression bar 13 is covered by this baffle plate 22, and is used for preventing compact heap 14 from exiting from "T"-shaped groove 13a.Four compression springs 23 vertically it are provided with between the bottom land of described compact heap 14 upper surface and "T"-shaped groove 13a, these four compression springs 23 are arranged on four summits of same rectangle, so it is easy to apply pressure to compact heap 14 equably, in order to compact heap 14 is pressed on workpiece end face equably.
From Fig. 1,2 can be seen that, 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.The inner of described locking rod 19 is tip end, and this tip end can contact with the profile of tooth of described gear 15 after connecting the via on limit and connecting plate 18 through n shape part 17, 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.
The foregoing is only presently preferred embodiments of the present invention, not with the present invention for restriction, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
