Abstract

The utility model relates to a back-and-forth moving device of a bridge type stone cutting machine, which mainly comprises a side beam sliding ram, a side beam, a screw and a bevel gear. The side beam sliding ram is sleeved on convex side parts on the two sides of a U-shaped groove in thea side beam through matching of a groove at the bottom of the side beam sliding ram, and the side beam sliding ram is driven through transmission of the screw to slide smoothly on the side beam. The traditional rolling friction is changed into sliding friction, the contact area is large, the operation is smooth with no shaking, the force is uniform, and a cutter holder can be driven to rotate in different sections through movement of the moving mechanism, so that the processed surface of stone is smooth and good effects can be achieved.

Description

A kind of bridge-type stonecutter move forward and backward device

Technical field

The utility model belongs to a kind of device in the processing stone material plant equipment, and what be specifically related to is a kind of device that moves forward and backward that is used for a kind of bridge-type stonecutter.

Background technology

The bridge-type stonecutter is a kind of processing of stone machinery, and this machinery can process the stone material of wide format, and therefore, the bridge-type stonecutter is widely used in the field of stone processing.

Present existing bridge-type stonecutter generally includes a crossbeam, two side bars, and moves the knife rest that seat, a movable stand and are equipped with saw blade; Crossbeam is to be erected between two side bars; And be equipped with between crossbeam and the side bar along side bar direction mechanism movably, described travel mechanism includes movable stand and moves seat, and movable stand is mounted in and moves on the seat; Movable stand is to move rolling on the seat through roller; And move before passing on from one to another trend through gear, the knife rest that saw blade is housed is mounted on the bottom part of movable stand, carries out the burst displacement thereby drive knife rest through moving of travel mechanism.

In view of the side bar device of above traditional structure bridge-type stonecutter, in cutting stone material, movable stand leans on two rollers moving rolling on the seat; And move forward through gear drive, its shortcoming is: movable stand is little with mobile seat contact-making surface, when the cutting of machining large wide format stone material; As easy as rolling off a log generation shake, stressed not steady, thus cause the cutting power of grafting saw blade on knife rest not steady; Cutting stone material surface irregularity, machining accuracy are not high, make side bar short service life simultaneously; Scrap easily, need troubles such as often maintenance.

Summary of the invention

The purpose of the utility model provides a kind of reasonable in design, and long service life changes sliding friction into by the rolling friction on traditional side bar, and contact area is big, steadily, the bridge-type stonecutter that does not rock move forward and backward device.

The utility model is realized through following technical scheme: a kind of bridge-type stonecutter move forward and backward device, mainly form by side bar ram, side bar, screw mandrel and conical gear;

The said wedge protuberance that is structure as a whole with side bar that is provided with along the axis direction of side bar and at side bar outer side edges medium position; The axis direction of the upper end edge side bar of side bar also is provided with the U-shaped groove, the limit portion of the both sides protrusion of U-shaped groove upper edge axis direction;

The bottom of side bar ram be provided with the U-shaped groove on the corresponding groove of limit portion of both sides protrusions; The side bar ram is installed in the limit portion of U-shaped groove both sides protrusion in the side bar through the identical socket of the groove of its bottom; The inboard of side bar ram is to be anchored on the screw mandrel through feed screw nut and hex bolts, and promptly the side bar ram is made the translation slide action on side bar with the transmission of screw mandrel.

Two tops of side bar are respectively equipped with side bar front end-plate and side bar end plate; And screw mandrel is mounted in this U-shaped groove; And an end of this screw mandrel couples together through taper roll bearing and side bar end plate, and the top of extending its screw mandrel one end is equipped with burst dial and conical gear; The other end of screw mandrel couples together through thrust ball bearing and side bar front end-plate, and the top of extending its screw mandrel other end is equipped with the burst counting device.

The beneficial effect of the utility model embodies and is: the side bar ram is installed in the limit portion of U-shaped groove both sides protrusion in the side bar through the identical socket of the groove of its bottom, and drives side bar ram smooth sliding on side bar through the screw mandrel transmission, changes sliding friction into by traditional rolling friction; Contact area is big; Steadily, do not rock and it is stressed evenly, carry out the burst displacement thereby drive knife rest through moving of travel mechanism; Make the stone surface that processes smooth, effective.

Description of drawings

Below in conjunction with accompanying drawing the utility model is carried out detailed explanation.

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A place profile among Fig. 1.

Fig. 3 is the C place enlarged diagram among Fig. 1.

Fig. 4 is the B place enlarged diagram among Fig. 1.

Be the concrete title of each sign among the figure below: 1 screw mandrel, 2 side bar rams, 3 feed screw nuts, 4 hex bolts, 5 side bars, 6 burst counting devices, 7 side bar front end-plates, 8 side bar end plates, 9 burst dials, 10 conical gears, 11 taper roll bearings, 12 thrust ball bearings, 51 wedge protuberances, 52U connected in star, 53 limit portions, 54 limit portions, 21 grooves, 22 grooves.

The specific embodiment

Like Fig. 1 to shown in Figure 4, a kind of bridge-type stonecutter move forward and backward device, mainly form by side bar ram 2, side bar 5, screw mandrel 1 and conical gear 10;

Saidly be provided with the wedge protuberance 51 that is structure as a whole with side bar 5 along the axis direction of side bar 5 and at side bar 5 outer side edges medium positions; The axis direction of the upper end edge side bar of side bar 5 also is provided with U-shaped groove 52, the limit portion (53,54) of the both sides protrusion of U-shaped groove 52 upper edge axis directions;

The bottom of side bar ram 2 be provided with U-shaped groove 52 on the corresponding groove of limit portion (53,54) (21,22) of both sides protrusions; Side bar ram 2 is installed in the limit portion (53,54) of U-shaped groove 52 both sides protrusion in the side bar 5 through the identical socket of the groove (21,22) of its bottom; The inboard of side bar ram 2 is to be anchored on the screw mandrel 1 through feed screw nut 3 and hex bolts 4, and promptly side bar ram 2 is made the translation slide action with the transmission of screw mandrel 1 on side bar 5.

Two tops of side bar 5 are respectively equipped with side bar front end-plate 7 and side bar end plate 8; And screw mandrel 1 is mounted in this U-shaped groove 52; And an end of this screw mandrel 1 couples together through taper roll bearing 11 and side bar end plate 8, and the top of extending its screw mandrel 1 one ends is equipped with burst dial 9 and conical gear 10; The other end of screw mandrel 1 couples together through thrust ball bearing 12 and side bar front end-plate 7, and the top of extending its screw mandrel 1 other end is equipped with burst counting device 6.

The utility model moves forward and backward device, applies on the bridge-type stonecutter, and its side bar skid need mate two covers, can make things convenient for machining large wide format stone material; This side bar skid slides on side bar 5 through side bar ram 2, and it is stressed steadily, changes sliding friction into by traditional rolling friction; Contact area is big, steadily, does not rock and it is stressed evenly; Carry out the burst displacement thereby drive knife rest, make the stone surface effect that processes smooth, effective through moving of travel mechanism.
