Description
Technical field
The utility model relates to a kind of carpenter's processing machine, particularly relates to a kind of planer lifting actuator.
Background technology
As shown in Figures 1 and 2, existing a kind of carpenter's flat plane machine includes a base 1, four and is arranged on screw rod 2 on this base 1, one to should base 1 and be installed in the cover 3 at described screw rod 2 tops, a tool rest unit 4 and a gear unit 5 that is arranged on the described screw rod 2 along a vertical direction Y.This gear unit 5 has chain 502 on described sprocket wheel 501 of most sprocket wheels that are installed in screw rod 2 bottoms 501, winding, one and is installed in the tumbler 503 of screw rod 2 top ends wherein and two in order to adjust the adjustment idle pulleys 504 of chain 502 tension force.When rotating this tumbler 503 and drive wherein a screw rod 2, just can see through the continuous action relation of sprocket wheel 501 and this chain 502, drive other screw rod 2 and rotate, and make this tool rest unit 4, to be applicable to the sheet material processing of different-thickness along screw rod 2 upper and lower lifting displacements.
Though utilize above-mentioned structure can make this tool rest unit 4 reach the purpose of adjusting displacement, but after using a period of time, this chain 502 tends to get loose situation, so that screw rod 2 can't be successfully by Synchronous Transmission, must operation adjust idle pulley 504 this moment, to finish the maintenance work that tightens this chain 502, so in operation, comparatively bother.
The utility model content
The purpose of this utility model is not need to adjust chain tension and just can produce synchronously driven planer lifting actuator providing a kind of.
Planer lifting actuator of the present utility model, this planer also comprise a base and a tool rest unit that is arranged on this base top.This transmission device has two and is located in this base and first screw rod that supplies this tool rest unit spiral shell to establish along a vertical direction axle, two fulcrums are located in this base and second screw rod that supplies this tool rest unit spiral shell to establish, two first driving wheels that are installed in described first screw rod one end, two second driving wheels that are installed in described second screw rod one end, two are attached at described first respectively, drive link between two driving wheels, two sprocket wheel and the chains of a winding on described sprocket wheel that are installed on the first screw rod opposed end, described drive link respectively have first drive and second drive that meshes with second driving wheel that mesh with first driving wheel.
The beneficial effects of the utility model are: utilize this transmission device overall co-ordination, when wherein one first screw rod is driven, just can makes that first and second screw rod reaches synchronous rotation, and make the tool rest unit reach the lifting purpose with respect to base.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated:
As shown in Figure 3, the utility model planer lifting actuator 100, this planer also comprise a base 200, a tool rest unit 300 that is arranged on these base 200 tops.
This transmission device 100 has two and is located at first screw rod 10 in this base 200 along a vertical direction Y-axis, two be parallel to described first screw rod 10 and also axle be located at second screw rod 20 in this base 200, two first driving wheels 30 that are installed in described first screw rod 10 bottoms, two second driving wheels 40 that are installed in described second screw rod 20 bottoms, two respectively along being attached at described first perpendicular to vertical direction Y, two driving wheels 30,40 drive link 50, two sprocket wheel 60 and the chains 70 of a winding on described sprocket wheel 60 that are installed on first screw rod, 10 bottoms.
The top ends of described first and second screw rod 10,20 is to establish for these tool rest unit 300 spiral shells, and first screw rod 10 and second screw rod 20 are reverse thread.
First and second driving wheel 30,40 of present embodiment is a bevel type gear, and the position is below this base 200.
Described drive link 50 also is that axle is located at this base 200 belows, and respectively have one along horizontally extending rotating shaft 51, one be installed in these rotating shaft 51 1 ends and with first drive 52 of first driving wheel, 30 engagements and one be installed in these rotating shaft 51 the other end and with second drive 53 of second driving wheel, 40 engagements.Described first and second drive 52,53 also is a helical gear.
Described sprocket wheel 60 is arranged on 30 of this base 200 and first driving wheels.
But this chain 70 is interlock first screw rods 10 to rotate synchronously and in the same way.
Fig. 4 and shown in Figure 5 for another example, when the operator drives wherein one first screw rod 10 rotations, utilization is installed in the sprocket wheel 60 of first screw rod, 10 bottoms and the setting of chain 70, other one first screw rod 10 also can be rotated synchronously and in the same way, and when first screw rod 10 rotates, utilize the effect of first drive 52 and 30 engagements of first driving wheel, second drive 53 and 40 engagements of second driving wheel, the rotational power of first screw rod 10 will see through drive link 50, drives two second screw rods 20 simultaneously and rotates towards the direction in contrast to first screw rod 10.Though the rotation direction of first and second screw rod 20 is on the contrary, because first screw rod 10 and second screw rod 20 are reverse thread, so just can drive the action that this tool rest unit 300 produces lifting synchronously.
Therefore, the utility model utilizes the setting of drive link 50 can make first screw rod, 10 synchronous interlock second screw rods 20, utilize cooperating and can making two first screw rods 10 produce synchronously, rotate in the same way of sprocket wheel 60 and chain 70, and make tool rest unit 300 reach the lifting purpose with respect to base 10.And the length of this chain 70 is short, even after using a period of time, this chain 70 also is not easy to get loose situation, thus the tension force of the chain 70 of length adjustment when not required, thus comparatively simple in operation, there is not the problem of keeping in repair yet.
