Abstract
Abstract The invention provides a circumference scriber which comprises a scale, a scribing pen disposed on the end part of the scale, and a slide block arranged on the scale and corresponding to the scribing pen. The circumference scriber can accurately draw lines on the radial circumference of a cylinder and has convenient use.
Description
D e s c r i p t io n CIRCUMFERENCE SCRIBER Field of the invention The invention relates to the casting field, in particular to a circumference scriber used in a casting process. Background of the invention A cylindrical mould is needed in the course of a casting process, lineation requires to be performed on the radial circumference of the cylindrical mould, and the traditional tool has much trouble in use. Usually, a ruler is used to draw straight lines, and because circumference is curved, the ruler is straight and thus can not accurately draw a line; and alternatively, a caliper can be used for lineation, but it is inconvenient that different circumference diameters require different calipers. Summary of the invention The object of the invention is to provide a circumference scriber which can accurately draw lines on the circumference of a cylinder and has convenient use. In view of the above technical problems, the invention employs the following scheme: a circumference scriber comprises a scale, a scribing pen disposed on the end part of the scale, and a slide block arranged on the scale and corresponding to the scribing pen. Preferably, a fastening bolt corresponding to the scale is arranged on the slide block to positioning the slide block on the scale.
D e s c r i p t io n Preferably, the bottom of the slide block is lower than the bottom of the scribing pen so as to be convenient for lineation. The invention has the following advantages: The technical scheme of the invention provides a circumference scriber which can accurately draw lines on the radial circumference of a cylinder and has convenient use. Brief description of the drawings Figure 1 is a structural diagram of the invention; and Figure 2 is a schematic diagram of the invention in use. Detailed description of the embodiment Referring to figure 1, a circumference scriber comprises a scale 1, a scribing pen 2 disposed on the end part of the scale 1, and a slide block 3 arranged on the scale I and corresponding to the scribing pen 2, a fastening bolt 4 corresponding to the scale I is disposed on the slide block 3, and the bottom of the slide block 3 is lower than the bottom of the scribing pen 2. Referring to figure 2, in practice use, the slide block 3 moves on the scale I freely to adjust the length and can be fixed by screwing the fastening bolt 4 for fixation, the lower part of the slide part 3 is butted on the end surface of a cylindrical structure, the lower end of the scribing pen is a penpoint which contacts with the curved surface, an accurate and clear line appears on the circumference by holding and radially moving the slide block 3, and the operation is very convenient.
