Background technology

In the industrial production, need after work piece production to store and transhipment.At present, the general wooden case that adopts packs change speed gear box, then transports.The defect of existing mode is: 1, need dismounting wooden case during transhipment, use inconvenience, efficiency low; 2, the structural strength of wooden case is poor; 3, the cost of wooden case is high.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of compact conformation simple, easy to use holding down assembly, for being held down assembly Work-sheet pressing on base plate by this.

The technical solution of the utility model is as follows: one holds down assembly, it is characterized in that: comprise and connect 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 level is fixed with an orienting sleeve (12), a horizontally disposed depression bar (13) is sliding combined with in this orienting sleeve, 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 be provided with four Compress Springs (23) between the bottom land of described compact heap (14) upper surface and "T"-shaped groove (13a), these four Compress Springs (23) are arranged on four summits of same rectangle;

Described gear (15) is through after the via hole on adapter sleeve (10), engage with described tooth bar (11), this gear empty set is on gear wheel shaft (16), and gear wheel shaft (16) is installed in adapter sleeve (10) outside; Two sides of described n shape part (17) are hinged with gear wheel shaft (16) two ends respectively, one piece of connecting panel (18) is installed with between these two sides, described locking rod (19) the inner is through after the via hole on n shape part (17) connection side and connecting panel (18), 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), the bar hole bearing fit that the two ends of this guide plate are corresponding with on described n shape part (17) two sides respectively, and between guide plate (20) and described connecting panel (18), clamping a return spring (21), 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 is connected with one piece of base plate.During use, first by Workpiece fixing on base plate, then pull out locking rod (19), at this moment can move up and down tooth bar (11), thus move 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), thus the inner of locking rod (19) is contacted with the profile of tooth of gear (15), the so just rotation of energy limiting gear (15), thus prevent tooth bar (11) from moving up and down, and then preliminary by Work-sheet pressing on base plate.Simultaneously, between profile of tooth due to tooth bar (11), there is gap, so not easily workpiece pressing very effectively, at this moment the end face of compact heap (14) and workpiece just can be very effectively made to be close to by four Compress Springs (23), thus workpiece pressing effectively further.

Adopt above technical scheme, the structure originally held down assembly is simple, compact, easy to implement, and easy to use laborsaving, and by tooth bar and Compress Spring reliably by Work-sheet pressing, thrust is large, so just conveniently stores and transports.

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 convenient to pull out locking rod (19), and the inner of locking rod (19) is tip end, the inner of locking rod (19) so just can be made reliably to contact with the profile of tooth of described gear (15).

Beneficial effect: the structure originally held down assembly is simple, compact, easy to implement, and easy to use laborsaving, by tooth bar and Compress Spring reliably by Work-sheet pressing, thrust is large, so just conveniently stores and transports.
