Abstract

The utility model relates to a woodworking tool, particularly a universal angle ruler for replacing woodworkers to mark lines. The utility model comprises a horizontal angle scale and a level angle ruler which are assembled on a saw table by a saw blade bedplate. The horizontal angle scale is fixedly arranged on a stroke sliding plate which can slide in the guiding groove between the saw blade bedplate and the saw table. The inner part of a groove of the level angle ruler is provided with horizontal alignment fine adjustment which can be replaced by a vertical angle disc with vertical alignment fine adjustment and a vertical angle ruler. The required components can be directly processed without marking lines, and the work efficiency and the quality of the member can be increased greatly.

Description

Universal angle board for woodworker

The utility model relates to a kind of wood working tool, the rule universal protractor of usefulness of particularly a kind of carpenter of replacement.

At present, for improving carpentry efficient and alleviating operator's labour intensity, various woodworking machinerys arise at the historic moment.But, when woodworks such as making door and window, furniture, in line, usually spend many times, and occur the bigger phenomenon of same specification error sometimes; Simultaneously because of manual operations, blanking is inaccurate, also easily produces the collimation error, causes goods after the processing to have to walk chi, outer disadvantage such as not tight in tight, does not reach designing requirement, can't guarantee Products Quality.Especially the member in the goods of going into operation in enormous quantities, lap-joint is 45 or 60 ° of angles mutually, or is polygon goods member, angle during line generally all requires accurately, yet after the processing, formed angle is often inaccurate, do not reach designing requirement, so more cannot say for sure to demonstrate,prove Products Quality.

The purpose of this utility model provides a kind of improved wood working tool, and it can overcome above-mentioned shortcoming fully, does not need line can directly process desired member, can significantly improve operating efficiency and component quality.

The purpose of this utility model is achieved in that on the buck of existing annular saw, utilize saw blade platen assembling horizontal angle scale and level angle chi, wherein the horizontal angle scale is packed on the stroke slide plate, the stroke slide plate can slide in the gathering sill between saw blade platen and buck, one end of level angle chi is hinged on the horizontal angle scale, and utilize the clamping screw location, in the groove of level angle chi level is housed line is finely tuned.The diverse location of adjustment level angle chi and level need not be rule to the position to the line chi in the line fine setting, can process desired member shape.If the level of level angle chi is had vertically the vertical angle scale replacement of line fine setting and vertical angle chi the line microcall, then can rule, directly process member and horizontal plane become various angles with vertical plane shape.

Because the utility model adopts and may rotate to level angle chi at any angle, on the level angle chi level is housed line is finely tuned, so can saw out member becomes plumbness with the saw blade plane end face at any angle.By adjust on the vertical angle chi vertically to line fine setting and level angle chi, can also saw out and saw blade plane off plumb end face at any angle.All can locate after each parts adjustment of this device, thus the member that processes, although do not rule, its processing dimension can both be controlled on the same specification, each junction, assembling back can not occur walking chi and outer tight in not tight phenomenon, can guarantee effectively to significantly improve operating efficiency by component quality.

Below in conjunction with accompanying drawing the utility model is further described.

Describe concrete structure of the present utility model and working condition in detail according to Fig. 1～6.This device comprises stroke slide plate 3, horizontal angle scale 4, level angle chi 5, level is to line fine setting, scale 7, vernier 8 and have vertical angle chi 15 and vertical vertical angle scale 16 to line fine setting 14, wherein horizontal angle scale 4 is loaded into one with stroke slide plate 3, utilize saw blade platen 2 that stroke slide plate 3 is assembled on the buck 1, and stroke slide plate 3 can be slided in the gathering sill of 1 of saw blade platen 2 and buck.Horizontal angle scale 4 is processed with two annular concentric slotted eyes, is hinged with level angle chi 5 on it.When level angle chi 5 rotates to institute's required angle, utilize the clamping screw location that is assembled in the cannelure, in level angle chi 5 grooves level is housed line is finely tuned, level is finely tuned by line chi 9, bearing 10, sleeve pipe 12 and tightening screw rod 11 are formed line.Can in sleeve pipe 12, move and utilize tightening screw rod 11 location vertically to line chi 9.Scale 7 also is housed on the level angle chi 5, utilizes fixing card 6 to be packed on the level angle chi 5.The long and short vernier 8 of control member is enclosed within on the scale 7, and reinforces with the holding screw location.During operation, when utilizing horizontal angle scale 4 tool member, level angle chi 5 transferred to saw blade become arbitrarily angled, can saw member facet (side) and saw blade plane at an angle of 90, head-on (top) becomes end face at any angle.When member need be sawed joint tongue, its head-on, when shoulder all need be sawed in the back side (following), it is dark earlier buck 1 to be transferred to desired saw, level angle chi 5 transfers the location, back to reinforce, and member head-on down, an end is close to the vernier 8 on the scale 7 again, carry out journey slide plate 3 forward, can saw out shoulder head-on.The member upset back side down, the adjustment level to line fine setting to reinforcing behind line chi 9 location, make shoulder rest head-on tightly to line chi 9, carry out journey slide plate 3 forward, can saw out desired flat shoulder (head-on, the shoulder at the back side is all at same vertical plane), move back shoulder or rise shoulder (head-on, the shoulder at the back side is not at same vertical plane).

Level to line fine setting taking-up, is replaced with vertical angle scale 16, adjust the angle of level angle chi 5 and vertical angle chi 15 respectively, can saw out desired member shape.After wherein hinged vertical angle chi 15 is adjusted angle on the vertical angle scale 16, reinforce with the clamping screw location.Be fixed on the vertical angle scale 16 vertically in the line fine setting 14 to line chi 13, reinforce by the holding screw location that is assembled in movable guide rod end.Scale 7 on the vertical angle chi 15 is still reinforced with fixing card 6, utilizes vernier 8 control members long and short.When member need be sawed out facet and saw blade plane out of plumb, head-on or the back side is parallel with saw blade or when becoming at any angle end face, earlier vertical angle chi 15 location are reinforced on the desired angle of facet, adjusting level angle chi 5 again makes it and saw blade plane at an angle of 90 or after arbitrarily angled, reinforce the location, member one end is close on the vernier 8 of vertical angle chi 15 scales 7, carries out journey slide plate 3 forward, can saw out desired member shape.Suitably adjust the angle of vertical angle chi 15 and level angle chi 5, can process the oblique shoulder of member requirement or facet and head-on all become end face at any angle.
