Description

Adjustable spacing wheel

Technical Field

The invention relates to hardware tools, in particular to an adjustable spacing wheel for quickly marking the positions of equidistant holes.

Background

In the processing and manufacturing places of leather materials and the like, in particular to manual leather material processing workshops, a tool called a spacing wheel is commonly used for carrying out equidistant marking and positioning operation before sewing or thread taking, the tool is generally composed of a handle, a wheel arm, a wheel shaft, a rotating wheel and a conical tip, the rotating wheel is integrally in a round cake shape, the rotating wheel is sleeved on the wheel shaft through a central hole and can rotate around the shaft, the conical tip is uniformly fixed on the circumference of the outer edge surface of the rotating wheel, when the tool is used for operating, the fabric is rolled on the paved fabric through the rotating wheel and the conical tip, uniformly distributed conical tips fixed on the rotating wheel can sequentially prick uniformly distributed marks on the fabric, the straight line distance between the conical tips is the mark distance on the fabric, and therefore, an accurate and regular conical hole position is provided for the next sewing or thread taking operation; in actual work, because different work pieces differ in the size requirement of interval, the line pitch size requirement of receiving of same work piece in different position is also many to be different, for this reason, the interval wheel of this kind of fixed awl point just is difficult to satisfy the requirement that multiple interval was marked, and the processing place often needs to be equipped with the interval wheel that many intervals are different and come frequent change side and can satisfy the needs, and is more loaded down with trivial details and fragmentary, brings a great deal of inconvenience for the operation.

Disclosure of Invention

The invention aims to provide a novel technical scheme of an adjustable spacing wheel, which can solve the problems.

The technical scheme of the invention comprises the following steps: the rotary wheel is provided with a round cake-shaped part in the central area of one side surface of the rotary wheel, and then a round cavity is formed, and conical teeth are uniformly processed on one surface of the round cake-shaped part which faces the cavity, so that the round cake-shaped part becomes an adjusting wheel; the circumference of the outer edge surface of the rotating wheel is uniformly processed with a plurality of same screw holes distributed in a radial shape, each screw hole is internally connected with a screw rod-shaped conical rod in a threaded manner, the outer end of the conical rod is processed into a conical tip and extends outwards out of the screw hole, the inner end of the conical rod passes through the screw hole and extends into the containing cavity at the center of the rotating wheel, key grooves which are uniformly distributed and are along the axis of the conical rod are processed on the circumference of the wall surface of the conical rod, a key groove which is meshed and connected with the key groove on the conical rod is processed on the wall surface of the central circular hole of the conical rod, the conical rods are connected with the key grooves at the inner ends of the conical rods in a meshing and sliding manner through the key grooves at the centers of the conical rods to be connected with the conical rods, meanwhile, the adjusting wheel is meshed with the conical teeth connected with the inner ends of the conical rods in position through the conical teeth on the adjusting wheel, the, a locking nut is connected to the part of the rotating shaft, which is positioned on the outer side of the adjusting wheel, in a threaded manner so as to lock the position of the adjusting wheel; the adjusting wheel is rotated to drive the bevel gears to synchronously rotate and further drive the conical rods to rotate, and the conical rods axially move in the respective screw holes relative to the screw holes, so that the size of the circumference formed by the conical tips is adjusted, and the spacing distance between the conical tips is also adjusted.

The invention has the beneficial effects that: it can be adjusted to different distances to meet the process requirements for marking the impressions.

Detailed Description

The design is illustrated below with reference to the accompanying drawings.

As shown in fig. 1, 2, 3, 4, and 5, the spacing wheel of the present design includes a handle 8, a wheel arm 3, a cone tip 1, a rotating wheel 2, and a wheel shaft 4, wherein a pie-shaped part is cut out from a central area of one side surface of the rotating wheel 2, i.e., the left side surface in the example illustration, to form a circular cavity 11, as shown in fig. 4 and 5, a conical tooth 12 is uniformly machined on a surface of the cut-out pie-shaped part facing the cavity to make the pie-shaped part become an adjusting wheel 6, i.e., the adjusting wheel is actually a bevel gear capable of engaging with the bevel gear and transmitting motion force; a plurality of same screw holes 10 distributed in a radial shape are uniformly processed on the circumference of the outer edge surface of the rotating wheel 2, each screw hole is internally connected with a screw rod-shaped conical rod 5 in a threaded manner, the outer end of each conical rod is processed into a conical tip and extends outwards out of the screw hole, the inner end of each conical rod passes through the screw hole and then extends into the containing cavity 10 at the center of the rotating wheel, key grooves which are uniformly distributed and along the axis of the conical rod are processed on the circumference of the wall surface of the conical rod, a key groove which is meshed and connected with the key groove on the conical rod is processed on the wall surface of the central circular hole of each conical rod 9, the conical rods 9 are connected with the key grooves at the inner ends of the conical rods 5 in a meshed and sliding manner through the key grooves at the centers of the conical rods to be connected with the conical rods, when the conical rods rotate, the conical rods; the adjusting wheel 6 is meshed with the bevel gears 9 connected with the inner ends of the conical rods 5 in place through the conical teeth 12 on the adjusting wheel, the conical tips 1 at the outer ends of the conical rods are positioned on the circumference of the same circle and the circle is concentric with the center of the rotating wheel 2, and the part of the rotating shaft 4, which is positioned on the outer side of the adjusting wheel, is in threaded connection with a locking nut 7 so as to lock the position of the adjusting wheel 6; when the distance between the conical points needs to be adjusted, the adjusting wheel can be rotated clockwise or counterclockwise, the conical points at the outer ends of the corresponding conical rods can move outwards in a radial or inward convergent manner, the diameter of a circle formed by the conical points is adjusted and changed, and the distance between the conical points is adjusted, for example, the distance between the original conical points is 6mm, and the distance between the conical points is adjusted to be 4mm by convergence.
