Description

For the transverse positioning mechanism before chopping block longitudinally transmission

Technical field

The utility model belongs to technical field of board processing, is related to the plant equipment for processing chopping block, more particularly to side Shape chopping block vertically move before transverse positioning mechanism.

Background technology

Chopping block is a kind of aily life necessitys, is divided from material, and common mainly has Wood chopping block and the major class of bamboo chopping block two, Plastic chopping block is comparatively used less.The shape of chopping block is based on square and circular, wherein minimal waste when square chopping block is processed, and Process is simple, relatively the most common.

In chopping block process, typically there are two kinds of situations to need to transmit chopping block, the first transmission is that chopping block exists Transmission between different station, it is not related to the process operation to chopping block in transmit process, thus it is very low to transmission required precision, herein It is called general transmission.Realize that the transport mechanism typically transmitted is relatively simple, common conveyer belt transmission, cylinder push, push away Disk transmission etc. can be directly applicable.Second of transmission is in the processing mode that cutter fixes chopping block movement, realizes that chopping block moves The transmission of dynamic processing, this transmission is because being related to processing action, and to ensure machining accuracy, the required precision to transmission is very high, herein Referred to as precisely transmission.

Precisely in transmission, chopping block needs can not in any direction outside moving direction by strict clamping position, chopping block Shift.Realize the transport mechanism that precisely transmits because and meanwhile be related to positioning clamping, its structure is relative complex.Therefore add in chopping block In the design of construction equipment, it will not will normally realize that the transport mechanism precisely transmitted is used to typically transmit, but for general transmission Transport mechanism is separately designed with accurate transmission, then the Origin And Destination of two kinds of transport mechanisms is linked up to form complete transmission Process.Exemplified by chopping block lateral end panel Xiyanping injection, its transmit process includes feeding transmission, Xiyanping injection transmission, discharging biography Send, wherein feeding transmission is low to required precision using general transmission with the transmission that discharges, and Xiyanping injection transmission is because being related to groove milling Precision, then should use precisely transmission.

In general transmission with precisely transmitting connecting points, because the chopping block lateral attitude precision typically transmitted is very low, accurate , it is necessary to first carry out located lateral to chopping block before transmission, clamping transmission is then performed again.The existing transverse direction for square chopping block is determined Position mode is that the anchor point of former and later two fixations is set in the side of chopping block first, and the second side sets activity orientation part, and activity orientation part is to anvil Plate is moved, and chopping block is pushed against on the anchor point of the first side fixation and completes to position.Chopping block is clamped by accurate transport mechanism after positioning And transmit.

But in reality, anyway anchor point is accurately set, it is still accidental to clamp chopping block by accurate transport mechanism Positioning runout positioning be present.

The content of the invention

The purpose of this utility model is, unavoidably even for being currently used for the located lateral before chopping block longitudinal direction is precisely transmitted Hair deviates the problem of positioning, where finding out questions and prospect, and proposes a solution.

Where finding out questions and prospect, through studying discovery repeatedly：Due to cutting accuracy problem in chopping block process, mostly It is preferable flat side that the side that number survey seems straight chopping block, which is not, but certain bending be present.This bending has very Big is irregular and uncertain, when this side of the corresponding two fixed anchor points of chopping block is recessed for middle protrusion front and back end Bending when, chopping block is needed after being positioned to during accurate transmission, and the part of protrusion can occur with preceding anchor point among side Conflict.Under the shock of preceding anchor point, chopping block it some times happens that skew (precisely transmission in clamping dynamics can not possibly be too Greatly, otherwise the clamped surface of chopping block can be destroyed), cause clamped chopping block to deviate positioning.

For above-mentioned reason, the utility model is improved detent mechanism, proposes that a kind of chopping block that is applied to longitudinally passes Transverse positioning mechanism before sending, the positioning before the accurate transmission in chopping block longitudinal direction that is particularly suitable for use in, it is characterised in that determined including corresponding The first keeper that first side of position chopping block horizontal direction is set, the second keeper and correspondingly it is positioned chopping block horizontal direction The 3rd keeper that second side is set；First keeper and the second keeper are set in the first side time interval for being positioned chopping block (direction transmitted when being processed using chopping block is before), the first keeper are located in front of the second keeper, and in a longitudinal direction the 3rd Keeper is between the first keeper and the second keeper；Both first keeper and second keeper combine composition to chopping block The first side lateral attitude restriction, the 3rd keeper forms the restriction to the second side lateral attitude of chopping block；First keeper, Second keeper, the 3rd keeper three combine the restriction formed to chopping block angle；At least the first keeper in three keepers With the activity orientation part that the 3rd keeper is movable setting.

The forward stroke for being arranged on the activity orientation part of the side of chopping block first is equal to start of a run target anchor point distance.3rd The forward stroke of keeper is more than the distance of start of a run target anchor point.

Further, the piston rod of first keeper and the first positioning cylinder is fixed, the first positioning cylinder cylinder Body phase is fixed for horizontal table.

Further, second keeper is preferably a positioning block, and the locating piece is fixed relative to horizontal station platform Set.

Alternatively, second keeper is similarly the activity orientation part of movable setting.Second keeper can also be adopted With the first keeper identical setting structure, i.e. the piston rod of the second keeper and a positioning cylinder is fixed, the positioning cylinder cylinder Body phase is fixed for horizontal table.

The piston rod of 3rd keeper and the second positioning cylinder is fixed, and the second positioning cylinder cylinder body is relative to water Flat workbench is fixed.

As an improvement, the piston glide direction of first positioning cylinder is obliquely installed relative to horizontal direction；When described When first keeper is in low level, the positioning action face of the first keeper flushes with the positioning action face of locating piece.

If the piston rod glide direction of the first positioning cylinder and the second positioning cylinder be arranged in parallel relative to horizontal direction, Then require that the positioning pressure of the first positioning cylinder have to be larger than the positioning pressure at least equal to the second positioning cylinder, it is no fixed second Under the promotion of position cylinder, the first keeper will be reversed, and can not realize positioning.The improvement side being obliquely installed using above-mentioned cylinder Case, then the cylinder of the pressure very little compared with the second positioning cylinder can be selected to be positioned to realize.

Similarly, if the second keeper is fixed using the piston rod also with a positioning cylinder identical with the first keeper, use In set the second keeper positioning cylinder piston glide direction it is also preferred that being obliquely installed relative to horizontal direction；

3rd keeper can have a variety of set-up modes, and chopping block is positioned in another side of chopping block as long as realizing .

The utility model beneficial effect is：

1st, by the way that preceding keeper in former and later two keepers of chopping block side is arranged into mobilizable mode, positioning After the completion of, keeper can exit anchor point, efficiently avoid when chopping block edge is not straight, be sent out in prelocalization part and chopping block The problem of life is collided and causes chopping block to offset；

2nd, on the one hand the first positioning cylinder being obliquely installed can effectively save the horizontal space shared by detent mechanism, make to add Construction equipment overall structure is more compact；On the other hand, without in order to avoid cylinder is horizontally disposed with when because detenting force be less than pair Side positioning cylinder thrust and the problem of caused legal position, it has to select the big cylinder body cylinder that thrust is bigger, it is small from thrust Small cylinder body cylinder, cylinder cost can be reduced, and further reduce occupancy of the cylinder to space.

It is apparent that transverse positioning mechanism described in the utility model is applicable not only to the processing of square chopping block, can also be applied In the processing of the other shapes of chopping block of one straight flange of band, other there is side injustice in be equally readily applicable to beyond chopping block The locating and machining of the sheet material of straight situation, can reach same technique effect.
