Description
Technical field
The utility model relates to the compression beam elevating mechanism on the folding brake.
Background technology
Manually folding brake is provided with and compresses upper slitter and compress down cutter.Compress upper slitter and be fixed on the compression beam, when compression beam moves up and down, compress upper slitter and can compress down cutter motion relatively, thereby finish tool setting, compress plate, unclamp action such as plate with compression beam.The elevating mechanism of existing manual folding brake compression beam is too simple, can not make compression beam hover over the function of a certain position, and loosely organized, kinematic accuracy is very low, this will have a strong impact on the quality of plate flanging and the durability of complete machine.
Summary of the invention
The purpose of this utility model provides and a kind ofly makes compression beam have hovering and the elevating mechanism of auto-lock function.
For achieving the above object, the utility model is taked following technical scheme:
Manual folding brake compression beam elevating mechanism, the nut that links together with compression beam that comprises that the screw shaft that only can rotate around self axis on the frame that is installed in folding brake, one and screw thread on the described screw shaft be complementary, and a handwheel that is used to make described screw shaft rotation; Described nut is installed on the described screw shaft, and the screw thread on the described screw shaft is a self-locking thread.
Design principle of the present utility model is as follows:
A side that screw shaft is had vertically or slightly the compression beam of being mounted obliquely within, nut and compression beam are linked together, when then driving screw shaft by handwheel, because screw shaft only can rotate around self axis and can not do axially-movable along self axis, the rotation military order of screw shaft and the nut that compression beam links together produce and move up and down, so compression beam can be done translation up and down with the rotation of handwheel.And because the screw thread on the screw shaft is a self-locking thread, compression beam is not having also can to hover over the optional position under the external force effect except that obtaining the holding power of screw shaft by nut.Remedied weak point of the prior art.
For obtaining enough holding power and self-locking effect preferably, the preferred rectangular thread of the screw thread of the above screw shaft to compression beam.
Screw shaft needs vertically to be provided with or to have slightly obliquely to be provided with usually, and the wheel shaft of handwheel is normally horizontally disposed, though the wheel shaft of handwheel can be considered to be connected with screw shaft is coaxial, but operate for ease of the workman, preferably meet at right angles between the axis of the axis of screw shaft and the wheel shaft of handwheel, carry out transmission by bevel gear.
The utlity model has following advantage: 1) compression beam can self-locking, and compression beam can be parked in the optional position, conveniently puts plate, tool setting; 2) compression beam can play when stressed to compress upper slitter, and sound construction is operated light, safety; 3) low to the machined requirement of side plate slideway, when tilting, screw shaft can adjust.

The specific embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
As shown in Figure 1, the elevating mechanism of present embodiment comprises screw shaft 1, nut 2 and handwheel 3.
Wherein, the top of screw shaft 1 is threaded portion 4, and the screw thread of threaded portion 4 is rectangular thread and is self-locking thread; The bottom of screw shaft 1 is a shaft 5, and shaft 5 matches with the bearing 6 of band mount pad.In addition, screw shaft 1 is by being arranged on the chimb 7 on the shaft 5 and being installed in relative position between the bearing 6 that 2 stop nuts 8 on the shaft 5 limit screw shaft 1 self and band mount pad.So after the bearing 6 of band mount pad was fixed to the frame 9 of folding brake, screw shaft 1 only can rotate around self axis, and can not do axially-movable along self axis.In the present embodiment, between the bearing 6 of chimb 7 and band mount pad, be provided with thrust ball bearing 10 and back-up ring 18; Between the bearing 6 of stop nut 8 and band mount pad, also be provided with thrust ball bearing 10, so screw shaft 1 can smooth and easyly rotate still under the situation of the weight of carrying compression beam 11.For the wheel shaft 12 with handwheel 3 carries out transmission, in the present embodiment, be provided with a driven wheel of differential 13 in the bottom of screw shaft 1, adopt key to be connected between described driven wheel of differential 13 and the screw shaft 1.
As shown in Figure 1, the handwheel 3 of present embodiment is installed in frame 9 sides of folding brake by ball bearing 14, the wheel shaft 12 of handwheel 3 is horizontally disposed, on wheel shaft 12, be provided with the drive bevel gear 15 that matches with driven wheel of differential 13, also adopt key to be connected between described drive bevel gear 15 and the wheel shaft 12.
As shown in Figure 1, the nut 2 of present embodiment is to be connected with compression beam 11 with the nut gland 17 that is used for clamp nut by Connection Block 16.
Rotate handwheel 3, screw shaft 1 also will rotate simultaneously.Because the axially-movable of screw shaft 1 is limited, so the nut 2 that is complementary with the screw thread of the threaded portion 4 of screw shaft 1 will produce axially-movable, consequently compression beam 11 will rise or decline together with nut 2.And because the screw thread of threaded portion 4 is a self-locking thread, compression beam 11 will possess the function of hovering with self-locking.
Should be noted that the rotation of screw shaft also can adopt motor-driven mode to realize except that driving by handwheel.
What this specification was enumerated is better embodiment of the present utility model only, and all equivalent technologies conversion of being done under operation principle of the present utility model and thinking all are considered as protection domain of the present utility model.
