Abstract

The invention relates to a carpenter saw which comprises a power supply box, a bracket and a working platform, wherein, the power supply box is internally provided with a motor, the right end of the power supply box is provided with a saw bit driven by the motor, one end of the bracket is connected with the right end of the power supply box in an inserting way, the upper end of the bracket is provided with at least two sliding rods which are arranged in parallel along the longitudinal direction by a support seat, each of the sliding rods is sheathed and connected with at least two sliding linear bearings, and the working platform is fixedly installed on the linear bearings; when the working platform slides, the linear bearings move along with the working platform in real time, so that the good matching between the linear bearings and the sliding rods can be ensured when in sliding, the vibration can be effectively reduced, and the processing quality of wood can be improved; in addition, the linear bearings can be directly used for limiting the movement of the working platform along the vertical direction and need not to be in virtue of other structures. Therefore, the carpenter saw is very simple in structure and convenient in installation and maintenance.

Description

A kind of carpenter's saw

Technical field:

The present invention relates to a kind of carpenter's saw that timber is processed of being used for.

Background technology:

In the prior art, as Chinese patent 200510016346.1 disclosed a kind of cutting board saw work bench for carpenter, comprise firm banking, sliding table, roller and polished rod bearing, upper surface, holder bottom and sliding table inner face are respectively equipped with groove, above-mentioned rollers one side is single roller, opposite side is two rollers, its two ends are respectively equipped with and holder and sliding table corresponding groove, roller is inlaid between firm banking and the sliding table, crouch respectively in the groove between firm banking and sliding table and the single roller polished rod bearing is housed, crouch in the groove between firm banking and two roller the polished rod bearing is housed, dress polished rod bearing crouches in another groove between sliding table and two roller, this structure in use, workbench adopts the line slip that fits into of polished rod bearing and roller, has effectively reduced friction, has prolonged service life, but this structure also exists deficiency:

First, in this structure, because roller is fixed on the mandrel, can not move axially with workbench and polished rod bearing, and in assembling process, certainly existing certain mismatch error between polished rod bearing and the roller, this will cause workbench to be easy to generate bigger vibration in slip, thereby reduce the crudy to timber;

The second, in this structure, slide with the level that realizes workbench that cooperates of roller by the polished rod bearing, the restraining force of workbench vertical direction need realize that its structure is very complicated by special constraint mechanism, maintenance, installation be difficulty relatively.

Summary of the invention:

The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of little and maintenance, carpenter's saw easy for installation of vibrating is provided.

According to a kind of carpenter's saw provided by the invention, comprise headstock, support and workbench, headstock inside is equipped with motor, right-hand member is provided with by motor-driven saw blade, support one end and headstock right-hand member are pegged graft, the support upper end is equipped with at least two by bearing and is the slide bar that parallel longitudinal is provided with, all be socketed with at least two slidably linear bearings on each slide bar, stationary table is installed on the linear bearing.

The present invention also has following attached technical characterictic:

Described support comprises a rectangular frame, this rectangular frame lower surface one side is provided with at least two legs, the opposite side that are vertical setting and is welded with at least two connecting axles that are vertical setting, described headstock right-hand member is welded with adapter sleeve, and connecting axle is plugged in the adapter sleeve.

All be connected with a latch on the described headstock front and back ends, described workbench medial surface is provided with the lock hole that cooperates with latch.

Have the chute of horizontally set on the described workbench upper surface, an assist location part that vertically is provided with is connected with dismountable baffle plate near assist location part one end place by being installed on the chute that bolt slides on the workbench on its longitudinal direction.

Described workbench upper surface and described headstock upper surface are contour.

On the described headstock dust cover is installed.

According to a kind of carpenter's saw provided by the invention, be with respect to the advantage of prior art:

First, among the present invention, linear bearing cooperates with the socket of slide bar can effectively eliminate alignment error, simultaneously, linear bearing is socketed on the slide bar, stationary table on linear bearing, and by linear bearing and slide bar slidably fit into line slip, when workbench slides, linear bearing is followed movable workbench in real time, good fit when having guaranteed to slide between linear bearing and the slide bar can effectively reduce vibration, improves the crudy of timber;

The second, among the present invention, stationary table is on linear bearing, and by linear bearing and slide bar slidably fit into line slip, simultaneously, but the moving of linear bearing immediate constraint workbench vertical direction, do not need by other structures, its structure is very simple again, and installation, maintenance is convenient.

Description of drawings:

Introduce the present invention in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present invention;

Fig. 2 extracts structural representation (dust cover is not shown) behind the adapter sleeve for connecting axle among the present invention.

The specific embodiment:

With reference to Fig. 1, Fig. 2, a kind of carpenter's saw of carrying according to the present invention, comprise headstock 1, support 2 and workbench 3, headstock 1 inside is equipped with motor 11, right-hand member is provided with the saw blade 12 that is driven by motor 11, headstock 1 right-hand member is welded with adapter sleeve 13, support 2 upper ends are equipped with at least two by bearing 4 and are the slide bar 41 that parallel longitudinal is provided with, all be socketed with at least two slidably linear bearings 42 on each slide bar 41, workbench 3 is fixedly mounted on the linear bearing 42, and on slide bar 41, slide by this linear bearing 42, when workbench 3 slides, linear bearing 42 can be followed workbench 3 in real time and be moved, good fit when having guaranteed to slide between linear bearing 42 and the slide bar 41, can effectively reduce vibration, improve the crudy of timber, support 2 comprises a rectangular frame 21, this rectangular frame 21 lower surfaces one side is provided with at least two legs 22 that are vertical setting, opposite side is welded with at least two connecting axles 23 that are vertical setting, connecting axle 23 is plugged in the adapter sleeve 13, realization support 2 is connected with headstock 1, support an end of this support 2 by headstock 1, make overall structure compact more, rationally, and, this structure is dismountable, during dismounting, connecting axle 23 is extracted adapter sleeve 13 get final product, after the dismounting, can change saw blade 12 easily, in addition, dust cover 9 is installed on the headstock 1, and the wooden night that saw blade 12 throws away in the time of can preventing work disorderly flies, and has guaranteed the cleaning of working environment and has avoided the injury of wooden night at random to operator's eyes.
