Abstract

A wheel line type high-efficiency carpenter line drawing device mainly depends on a single grooved wheel, a double grooved wheel, a line feeding wheel, a bottom line wheel and ink boxes matched with each other, which are connected by an annular line, to form a group of complete line drawing units for carrying out rapid line drawing work. The device can be made of wood or plastic, iron, aluminum metal and other materials.

Description

Carpenters scriber

This device belongs to the field of carpenter's operation tool.

Be engaged in the workman of carpenter processing in the past, in operations such as system tenon, grooving, normally adopted artificial setting-out, with ruler, angle square one by one workpiece draw somely, dimensional accuracy is not high, inefficiency, poor repeatability between each workpiece.

Afterwards in order to overcome above-mentioned shortcoming, adapt to the needs of producing in batches, some light instruments have been made, someone nails on several nails on little plank, adjust the distance of the head of a nail to little plank, during setting-out little plank and blank be close to and make vertical motion, the head of a nail is inscribed a rule vestige on blank, as the processing foundation, developed into again with the pattern fixation afterwards and carried out setting-out, promptly on a solid wood, saw several slits by concrete workpiece size, imbed the steel scrap saw blade, at the plank end nail lumps of wood be shelves heads, nails on batten in plank one side and does pattern, during setting-out blank is pushed against shelves and a pattern, knock blank with instrument, saw blade just carves a rule vestige, changes a dimensional requirement and will make cover instrument like this again, and is very inconvenient.Also having found further instrument in the recent period, is a key name of 87211446 patent for carpenter's vernier scriber as the patent No., though make moderate progress on comfort level, does not all obviously increase work efficiency and the setting-out degree of accuracy.

The design's purpose is exactly at above-mentioned shortcoming, for increasing work efficiency in batch process and workpiece accuracy, operation yield rate, and designs a kind of efficient line tool of line formula of taking turns.In large-scale pipeline production, can carry out rapidly mortise, the grooving operation of various different size workpiece, setting-out accurately.

Structure of the present utility model can be illustrated in conjunction with the accompanying drawings.

Fig. 1 is the efficient carpenter's line-plotting device of wheel line formula overall pattern.

Fig. 2 is wheel line formula setting-out cell schematics.

Fig. 3 is the line-plotting device vertical view.

Wherein, (single groove and double grooved pulley are equipped with respectively in its up and down both sides to setting-out post ［ 1 ］, post itself is screwed on the lateral strut ［ 4-2 ］ at support), (it comprises single sheave ［ 2-1 ］ to single sheave parts ［ 2 ］, print cartridge ［ 2-2 ］ they be assembled together soak the black degree of depth and account for 1/2 and take turns the place), (it comprises double grooved pulley ［ 3-1 ］ to double grooved pulley parts ［ 3 ］, print cartridge ［ 3-2 ］, they also are to be assembled together to soak the black degree of depth about 1/2 and take turns the place, all have aperture on the print cartridge wall, walk for toroid), (it comprises vertical steady arm ［ 4-1 ］ with the support ［ 4 ］ of vernier scale, be carved with the size sign on it, lateral strut ［ 4-2 ］, marked too the vernier size, vertical rod ［ 4-3 ］ supports whole framework), (each setting-out unit comprises three groups of toroids to toroid ［ 5 ］, from the aperture that the print cartridge wall is opened, walk, form the setting-out unit, wherein two groups of loop wires connect self setting-out post on place an order, double grooved pulley. They bear the setting-out function of former and later two faces of workpiece. Another loop wire connects two double grooved pulleys staggered relatively. In this line-plotting device bottom synchronizing bar ［ 6 ］ is housed, it is fixed on the downside of cradle ［ 7 ］, and with each setting-out unit in link to each other around the upper toroid of double grooved pulley, to reach the synchronous operation between each setting-out unit. Wherein on the cradle ［ 7 ］ centralizer ［ 7-1 ］ is housed also, to guarantee that workpiece is unlikely crooked in the setting-out process. The parallel sliding track ［ 7-2 ］ that is contained in frame bottom is for providing cradle to come and go movable track. The setting-out function of bottom surface is finished by two slotless wheel components ［ 8 ］, ［ 9 ］ on the processing work, wherein two no sheaves ［ 8-1 ］, ［ 9-1 ］ also soak respectively among separately print cartridge ［ 8-3 ］, ［ 9-3 ］, and be separately fixed on bottom line bar ［ 8-2 ］ and the steady arm ［ 9-2 ］, steady arm ［ 9-2 ］ is screwed on each corresponding setting-out post ［ 1 ］ again, extended position can be regulated by the scale of vertical vernier scale, to adapt to different setting-out workpiece.

In this device when operation, be placed on lineman's part to be painted and be close to centralizer on the cradle, carries out forward opposite one side, just can with the front and back sides of workpiece and upper bottom surface totally 4 lines once draw. Only need adjust screw when changing when setting-out requires, the relative position of setting-out post on band vernier scale support ［ 4 ］ be changed get final product, when drawing oblique line simultaneously with setting-out post ［ 1 ］ furnishing obliquity state, the at any angle oblique line section of can drawing.

Most preferred embodiment: made and tested into a line-plotting device, its lateral dimension is 2.5 meters, and vertically width is 40cm, vertical height is the large-scale plant of 35cm, 10 pairs of setting-out posts are installed, energy painter part full-size 15 * 15(cm), the batten of minimum dimension 1 * 1.5(cm), once finish 40 setting-outs, than improving 40 times of work efficiency with some setting-outs, this example gross weight 30Kg has characteristics such as setting-out is accurate, speed is fast, operating efficiency height, and cheap, be easy to make and operation.
