Abstract

The utility model relates to a packing cutter and mainly resolves problems of having burr, being easy to loosen and deform, and length inaccuracy affecting sealing effect of a packing notch. The packing cutter is characterized in that a notch capable of leading a knife to cut into is arranged at the left end of the longitudinal portion of a base with an L-shaped cross section, the transversal portion of the base is provided with scale, and a clamping device parallel to the longitudinal portion of the base is horizontally fixed on the top portion of the scale of the transversal portion; the middle portion of the clamping device is U-shaped, a fastening screw fixed on a fixing frame of the base is connected to the U-shaped middle portion of the clamping device, a packing is arranged in the space between the clamping device and the longitudinal portion, and a vernier is connected onto the base at the right end of the clamping device; and a V-shaped opening with a horizontal upper end is disposed at a position corresponding to the packing on the vernier, one end of the V-shaped opening is a sloping side which is parallel to the notch of the longitudinal portion of the base, and an opening arranged at a position corresponding to the scale of the base on the vernier is the central end face of the vernier. The packing cutter has the advantages of accurate cutting length and high production quality.

Description

The packing cutter

Technical field:

The utility model relates to a kind of cutter, particularly a kind of packing cutter.

Background technology:

Valve rod, axle sleeve or pump shaft etc. often use this filler of packing to seal, if want packing_seal effective, the packing two ends should contact closely, so the packing otch will have angle and neat.Artificial cutter cutting packing commonly used at present, be about to packing around valve rod that will twine or pump shaft one circle, measure approximate size, cut one section packing with artificial cutter commonly used in the daily life at ordinary times by this length, Qie Ge packing otch has burr like this, the easy loose distortion of packing, especially cutting angle and length are inaccurate, influence sealing effectiveness.

The utility model content:

Technical problem to be solved in the utility model is to overcome that the packing otch that exists in the background technology has burr and easy loose distortion, length is inaccurate and the problem that influences sealing effectiveness, and provide a kind of packing cutter, this packing cutter have Cutting Length accurately, make the high characteristics of quality.

The invention for solving the technical problem can reach by following technical solution: this packing cutter comprises base, the cross section is that the longitudinal component left end of L shaped base has the otch that can make the cutter incision, there is scale the lateral part, lateral part scale top, horizontal fixedly is parallel to the binding clasp of base longitudinal component, the binding clasp middle part is a U-shaped, be fixed in the U-shaped middle part that trip bolt on the fixed mount of base is connected in binding clasp, binding clasp and longitudinal component space are equipped with packing, connect vernier on the base of binding clasp right-hand member, there is the V-arrangement opening of a upper end level at the corresponding packing of vernier place, the other end of V-arrangement opening is a hypotenuse, this hypotenuse is parallel with the otch of base longitudinal component, it is vernier center end face that there is opening at scale place on the corresponding base of vernier, and the vertical edge of vernier center end face opening aligns with the top point of the V-arrangement of V-arrangement opening.

The scale unit of described base lateral part is 3.14mm; Align with an end of otch the zero point of described base lateral part scale; Described otch is a miter angle; Described base longitudinal component incision is fixed with cutter shaft, and cutter is connected on the base by cutter shaft.

The utility model is compared with the above-mentioned background technology can have following beneficial effect: this packing cutter is owing to adopt said structure, cutting angle and length are accurate, and defectives such as non-incision burr or the loose distortion of packing are made the quality height, this tool construction is simple, and is easy to carry.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

Among the figure: 1-cutter, 2-base, 3-opening, 4-vernier, 5-trip bolt, 6-vernier center end face, 7-packing, 8-binding clasp, 9-fixed mount, 10-otch, 11-cutter shaft.

The specific embodiment:

Below in conjunction with accompanying drawing will the utility model is described in further detail:

As shown in Figure 1, this packing cutter comprises base 2, and base 2 cross sections are L shaped, the longitudinal component left end has the otch 10 that can make cutter 1 incision above the base 2, fix a cutter shaft 11 near the base 2 longitudinal component otch 10, cutter 1 is connected on the base 2 by cutter shaft 11, so that the cutter cutting is more convenient; There is scale the lateral part below the base 2, and this scale is used to measure packing length; The scale top, horizontal fixes to clamp device 8, and binding clasp 8 is parallel to the base longitudinal component, and binding clasp 8 middle parts are U-shaped, and binding clasp 8 is equipped with packing 7 with the longitudinal component space, and longitudinal component is used for alignment packing 7 above the base 2, and binding clasp 8 is used for the clamping packing; Be fixed with fixed mount 9 on the base, trip bolt 5 on the fixed mount 9 is connected in the U-shaped middle part of binding clasp 8, connect vernier 4 on the base 2 of binding clasp 8 right-hand members, vernier 4 can slide on base 2, and there is a V-arrangement opening 3 at vernier 4 corresponding packings 7 places, and V-arrangement opening 3 upper ends are level on one side, the limit of the other end of V-arrangement opening is a hypotenuse, this hypotenuse is parallel with the otch 10 of base longitudinal component, and described otch is a miter angle, and purpose is to make the packing two ends of cutting be easy to tight connection; It is vernier center end face 6 that there is opening at scale place on the vernier 4 corresponding bases, and the vertical edge of vernier center end face 6 openings aligns with the top point of the V-arrangement of the V-arrangement opening 3 of vernier 4, is convenient to measure and reads scale numerical value; The scale unit of base lateral part is 3.14mm, and for the ease of measuring the length of packing 7, align with an end of otch 10 zero point of base lateral part scale.

This packing cutter using method and principle are: during the cutting packing, clamp packing, cut off along otch 10 with cutter, the packing corner cut is inserted in the vernier V-arrangement opening 3, base 2 unit scales are 3.14mm, press valve rod or pump shaft diameter and packing filling width sum, on the scale of base, get analog value, again vernier 4 is slided on this value, vernier center end face 6 vertical edges are aimed at corresponding graduation mark, and be screwed vernier 4, and packing 7 is placed binding clasp 8 and base longitudinal component space, clamp with binding clasp 8.For example the pump shaft diameter is 40mm, and the packing width is 12mm, itself and be 52mm, aim at scale 52 lattice on the base 2, downcut the length of packing, promptly the footpath girth is (40mm+12mm) π=163.28mm in the packing annular.

This tool construction is simple, and is easy to carry, and cutting angle and length are accurate, and defectives such as non-incision burr or the loose distortion of packing are made the quality height.
