Abstract
The utility model relates to a transmission mechanism of a plate shearing machine, which belongs to the technical field of metal plate processing machinery. The transmission mechanism of the plate shearing machine comprises a sliding block, a screw rod, a screw rod nut, an upper ball head, an upper ball head base, an upper press cover, a lower ball head, a lower ball head base and a lower press cover, wherein sliding block guide rails are arranged at the two sides of the sliding block; the sliding block can move up and down along the sliding block guide rails; the upper press cover is pressed on a lower port of the upper ball head base, so that the head part of the upper ball head is positioned in the upper ball head base to form an upper rotation pair; the tail part of the upper ball head extends downwards out of a center hole of the upper press cover; the lower press cover is pressed on an upper port of the lower ball head base, so that the head part of the lower ball head is positioned in the lower ball head base to form a lower rotation pair; the tail part of the lower ball head extends upwards out of a center hole of the lower press cover; the tail part of the upper ball head is connected with the tail part of the lower ball head through a connecting seat; the tail part of the upper ball head base is connected with the lower end of the screw rod; and the lower part of the lower ball head base is connected with the sliding block. In the transmission mechanism, the screw rod and the sliding block are connected through the two rotation pairs, so that the manufacturing difficulty is reduced, and the reliability is improved.
Description
Technical field
The utility model relates to a kind of plate shearing machine, relates in particular to a kind of transmission mechanism of plate shearing machine, belongs to sheet-metal working machine tool technical field.
Background technology
The transmission mechanism of existing plate shearing machine comprises screw mandrel and the feed screw nut who cooperatively interacts; Feed screw nut's periphery is provided with protruding circle and is supported on the frame through protruding circle; Feed screw nut's rotation under the driving of synchronous band, and drive screw mandrel and do oscilaltion campaign, link to each other with slide block below the screw mandrel; The both sides of slide block are provided with the slide block guide rail of control slide block movement direction, and the up-down of screw mandrel affects slide block to move up and down along slide block guide rail.Such structure must let movement locus and the slide block guide rail of screw mandrel keep highly parallel, if guarantee its precision through the means of processing and assembling, realizes that cost is very high, also suitable big of assembly difficulty, and reliability is difficult to guarantee.In case the precision between screw mandrel and the slide block guide rail does not reach requirement, will cause slide block not to be free to slide along slide block guide rail.
The utility model content
The purpose of the utility model is, overcomes the problem that exists in the prior art, and a kind of transmission mechanism of plate shearing machine is provided, and difficulty of processing is low, and reliability is high.
For solving above technical problem; The transmission mechanism of a kind of plate shearing machine that the utility model provided; Comprise slide block, screw mandrel and the feed screw nut who matches with screw mandrel; The both sides of said slide block are equipped with slide block guide rail and can move up and down along slide block guide rail, also comprise bulb, last ball cup, upper press cover, following bulb, following ball cup and lower cover; The head that the lower port that said upper press cover is pressed in ball cup will go up bulb is positioned to constitute in the ball cup goes up revolute pair, and said tail down of going up bulb is stretched out from the centre bore of said upper press cover; Said lower cover is pressed in down the port of ball cup and will descends the head of bulb to be positioned at down the following revolute pair of formation in the ball cup, and the said afterbody of bulb down upwards stretches out from the centre bore of said lower cover; The said afterbody of going up bulb links to each other with the said afterbody of bulb down through Connection Block, and said top of going up ball cup is connected the lower end of said screw mandrel, and the said bottom of ball cup down links to each other with said slide block.
With respect to prior art; The utility model has been obtained following beneficial effect: link to each other through two revolute pairs between screw mandrel lower end and the slide block; Last bulb can rotate as the joint in last ball cup, and following bulb can be rotating as the joint in the ball cup down, even the depth of parallelism generation deviation of the movement locus of screw mandrel and slide block guide rail; Because the regulating action of two revolute pairs, slide block still can move in slide block guide rail very swimmingly.This transmission mechanism is simple in structure, and is reliable and stable, greatly reduces process and assemble difficulty and manufacturing cost, shortened installation time, and improved the reliability of lathe.
Description of drawings
Fig. 1 is the sketch map of the transmission mechanism of the utility model plate shearing machine.
Among the figure: 1 frame, 2 screw mandrels, 3 feed screw nuts; The last ball cup of 4a, the last bulb of 4b, 4c upper press cover, 5 Connection Blocks, ball cup under the 6a, bulb under the 6b, 6c lower cover, 7 slide blocks, 8 slide block guide rails.
The specific embodiment
As shown in Figure 1; The transmission mechanism of the plate shearing machine of the utility model; Comprise screw mandrel 2, feed screw nut 3, go up ball cup 4a, go up bulb 4b, upper press cover 4c, bulb, ball cup 6a, lower cover 6c and slide block 7 down down, the both sides of slide block are equipped with slide block guide rail 8 and can move up and down along slide block guide rail.
The head that the lower port that upper press cover 4c is pressed in ball cup 4a will go up bulb 4b is positioned to constitute among the ball cup 4a goes up revolute pair, and the tail down of last bulb 4b is stretched out from the centre bore of upper press cover 4c.
The afterbody of last bulb 4b links to each other with the afterbody of following bulb 6b through Connection Block 5, and the top of last ball cup 4a is connected the lower end of screw mandrel 2, and the bottom of following ball cup 6a links to each other with slide block 7.
Link to each other through two revolute pairs between screw mandrel 2 lower ends and the slide block 7; Last bulb 4b can rotate as the joint in last ball cup 4a; Following bulb 6b can rotate as the joint among the ball cup 6a down; Even the depth of parallelism generation deviation of the movement locus of screw mandrel and slide block guide rail, because the regulating action of two revolute pairs, slide block still can move in slide block guide rail very swimmingly.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
