Description

TECHNICAL FIELD

[0001] The present application relates to the field of cutters, in particular to a variable-diameter waterline processing tool. BACKGROUND

[0002] The sealing surface of the valve is provided with a waterline, which plays a sealing role.

[0003] Since the waterline is composed of concentric multiple circles, the waterline cutter needs to be precisely adjusted in position multiple times, which is time-consuming and labor-intensive. For example, using a fixed cutter for processing is not convenient for adjustment, and replacing the cutter is time-consuming and labor-intensive. Using a machining center with turning function for processing is expensive and has high manufacturing cost.

[0004] In summary, how to realize the rapid processing of waterline has become a problem that researchers in the field urgently need to solve. CONTENT OF THE UTILITY MODEL

[0005] The technical problem to be solved by the present application is how to realize rapid adjustment and processing of waterline spacing.

[0006] To solve the above technical problems, the technical scheme adopted by the present application is as follows:

[0007] The utility model discloses a variable-diameter waterline processing tool, which comprises a tool shank, a plurality of cutting assemblies, a tire expander and a locking assembly.

[0008] In the present application, since the cutting tips of the waterline cutters on each cutting assembly are on circles of different diameters, rotating the tool shank drives the plurality of cutting assemblies to rotate, thereby realizing one-time processing of multiple circles of waterline.

[0009] When it is necessary to increase the processing diameter of the waterline, the lower pressing piece is rotated to make the wedge-shaped part descend. Since the wedge-shaped part and the tire expander are wedge-shapedly matched, the tire expander expands outward, driving the cutting tips of the waterline cutters of the cutting assemblies to move outward synchronously, thereby increasing the diameter of each circle of waterline. In addition, the spacing between the waterlines is also increased synchronously.

[0010] Because the inflation tire and the cutting assembly are connected by inserting, the inflation tire expands outward or shrinks inward, and the cutting assembly moves outward or inward synchronously with the inflation tire.

[0011] Because the cutting edges of the waterline cutter are at different positions, the waterline cutter can facilitate chip removal during cutting, and the cutting assembly in which the waterline cutter is arranged can be replaced conveniently when a cutting edge is damaged.

[0012] In order to illustrate the specific structure of the cutting assembly, the utility model adopts the cutting assembly comprising: a bracket arranged in a radial groove at the end face of the cutter handle; and the waterline cutter arranged on the bracket.

[0013] The waterline cutter is arranged on the bracket, and the bracket moves relatively in the radial groove to protect the waterline cutter from being damaged.

[0014] In order to illustrate the structure of the cutter holder, the utility model adopts the bracket being of L-shaped structure, which comprises: a horizontal section on which the waterline cutter is adapted to be placed; and a vertical section provided with a dovetail protrusion on the side close to the inflation tire.

[0015] The horizontal section is used for supporting and positioning the waterline cutter, and the vertical section is used for adjusting the spacing of waterline; when it is required to process waterline of other diameters, the bracket is replaced, that is, the thickness of the vertical section is increased or decreased to change the diameter of the processed waterline.

[0016] In order to realize the positioning of the waterline cutter and the bracket, the utility model adopts the horizontal section being provided with a limiting protrusion at the top; and the waterline cutter being provided with a limiting groove matched with the limiting protrusion.

[0017] The limiting protrusion and the limiting groove are matched to realize the positioning of the waterline cutter and the bracket.

[0018] In order to illustrate the specific structure of the inflation tire, the utility model adopts the inflation tire being of elastic ring structure; first deformation grooves and second deformation grooves are arranged on the circumference of the inflation tire at intervals; the first deformation grooves are arranged by extending downward from the top of the inflation tire; the second deformation grooves are arranged by extending upward from the bottom of the inflation tire; a groove is arranged on the circumference of the inflation tire, and a dovetail groove matched with the dovetail protrusion is arranged in the groove.

[0019] In the scheme, the inflation tire is an elastic member, the inflation tire expands outward, and the spacing of the first deformation grooves and the second deformation grooves increases; when the inflation tire is subjected to less force, the inflation tire will automatically shrink, and the spacing of the first deformation grooves and the second deformation grooves decreases.

[0020] The dovetail groove and the dovetail protrusion are matched to realize the inserting connection of the inflation tire and the cutting assembly, so that the cutting assembly is convenient to replace.

[0021] The purpose of the groove is to cooperate with the cutting assembly, and the waterline spacing is changed by the gradual change of the groove depth, the tire expanding elastic member gradually changes according to the different groove depth, and there are multiple specifications that can be adjusted and replaced, and the waterline processing with different spacings is suitable.

[0022] In order to illustrate the specific structure of the locking assembly, the utility model adopts the locking assembly, which comprises: a plurality of hole bodies which are arranged at the tool handle and located on the side corresponding to the cutting assembly; a locking part which is threadedly connected with the hole body and has an end portion abutting against the side surface of the waterline cutter;

[0023] In the scheme, by rotating the locking part, the end portion of the locking part abuts against the side surface of the waterline cutter, so as to limit the movement of the waterline cutter and realize the locking of the tool handle and the cutting assembly.

[0024] In order to further realize the locking of the waterline cutter, the utility model adopts the V-shaped groove which is arranged on the side surface of the waterline cutter and extends in the movement direction of the waterline cutter; and the end portion of the locking part has a tapered portion which is matched with the V-shaped groove.

[0025] When the tapered portion contacts the V-shaped groove, the locking of the tool handle and the cutting assembly is realized; when the tapered portion does not contact the V-shaped groove, the cutting assembly can only move linearly along the length direction of the V-shaped groove due to the limiting of the tapered portion.

[0026] In order to illustrate the reset of the expanded tire, the utility model adopts the reset blocking ring which is arranged at the center of the tire.

[0027] When the downward pressing part is rotated upward, the wedge-shaped portion gradually reduces the force acting on the tire, until the downward pressing part is rotated to the position where the reset blocking ring abuts against the wedge-shaped portion, the downward pressing part transmits the force to the wedge-shaped portion through the reset blocking ring, and drives the wedge-shaped portion to move upward synchronously, until the tire is completely reset.

[0028] The utility model has the advantages that the utility model is a variable-diameter waterline processing tool, since the cutting edges of the waterline cutters on each cutting assembly are located on circles with different diameters, the rotation of the tool handle drives the rotation of the multiple cutting assemblies, so that the multiple-circle waterline can be processed at one time, and the rapid processing of the waterline is realized.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0043] like Figures 1-5 As shown, this utility model is a tooling for machining watermark lines with variable diameter, comprising: a tool holder 1; a plurality of cutting components 2, which are equally distributed radially on the tool holder 1, wherein the tips of the watermark cutters 21 on each cutting component 2 are on circles of different diameters on the same plane; an expansion piece 3, which is disposed at the center of the tool holder 1, and its outer side is inserted and connected to the cutting components 2; a wedge-shaped part 4, which is disposed at the center of the expansion piece 3, and its inner wall of the expansion piece 3 is wedge-shaped; a lowering member 5, which is disposed at the center of the wedge-shaped part 4, and has a limiting part that abuts against the top of the wedge-shaped part 4, and its bottom end is threadedly connected to the tool holder 1; by rotating the lowering member 5, the wedge-shaped part 4 rises or falls, realizing the inward or outward expansion of the wedge-shaped part 3, driving the plurality of cutting components 2 to move synchronously inward or outward; and a locking component 6, which is adapted to fix the moved cutting components 2 to the tool holder 1;

[0044] In this solution, since the tips of the water ripple cutters on each cutting component are on circles of different diameters, the rotation of the tool holder drives the rotation of multiple cutting components, thus enabling the one-time processing of multiple water ripple lines.

[0045] When it is necessary to increase the machining diameter of the watermark line, simply rotate the lower pressure part to make the wedge part move downward. Since the wedge part and the expansion tire are wedge-shaped, the expansion tire expands outward, which drives the tip of the watermark cutter of the cutting component to move outward synchronously, increasing the diameter of each watermark line. In addition, the spacing between the watermark lines also increases synchronously.

[0046] Because the expansion tire and the cutting assembly are connected by an insert, the expansion tire expands outward or contracts inward, and the cutting assembly moves outward or inward synchronously with the expansion tire.

[0047] Because the cutting tips of the watermark cutter are all in different positions, it is beneficial for chip removal during cutting; if a cutting tip is damaged, it is also convenient to replace the cutting component where the watermark cutter is located.

[0048] To illustrate the specific structure of the cutting assembly, this utility model uses a cutting assembly 2 comprising: a bracket 22, which is disposed in a radial groove at the end face of the tool holder 1; and a water-patterned cutter 21, which is disposed on the bracket 22.

[0049] The watermark cutter is mounted on a bracket, which moves relative to the watermark cutter within a radial groove, protecting it from damage.

[0050] like Figure 5 As shown, in order to specifically illustrate the structure of the knife holder, the present invention adopts an L-shaped structure for the bracket, which includes: a horizontal section 221, on which the water ripple knife 21 is placed; and a vertical section 222, on which a dovetail protrusion 223 is provided on one side near the expansion tire 3.

[0051] The horizontal section is used to support and position the watermark cutter, while the vertical section is used to adjust the spacing of the watermark lines. When it is necessary to process watermark lines of other diameters, the diameter of the watermark lines can be changed by changing the bracket, i.e., increasing or decreasing the thickness of the vertical section.

[0052] like Figure 5 As shown, in order to achieve the positioning of the water ripple cutter and the bracket, the present invention adopts a limiting protrusion 224 at the top of the horizontal section 221; and a limiting groove that cooperates with the limiting protrusion 224 is provided at the bottom of the water ripple cutter 21.

[0053] The positioning of the water ripple cutter and the bracket is achieved through the cooperation of the limiting protrusion and the limiting groove.

[0054] like Figure 4As shown, to illustrate the specific structure of the expanded tire, the expanded tire 3 of this utility model is an elastic annular structure; the expanded tire 3 is provided with a first deformation groove 31 and a second deformation groove 32 spaced apart on its circumference; the first deformation groove 31 extends downward from the top of the expanded tire 3; the second deformation groove 32 extends upward from the bottom of the expanded tire 3; a groove 33 is provided on the circumference of the expanded tire 3, and a dovetail groove 34 that cooperates with the dovetail protrusion 223 is provided in the groove 33;

[0055] In this design, the expanding tire is an elastic element. As the expanding tire expands outward, the distance between the first deformation groove and the second deformation groove increases. When the force on the expanding tire decreases, the expanding tire will automatically retract, and the distance between the first deformation groove and the second deformation groove will decrease.

[0056] The dovetail groove and dovetail protrusion work together to enable the insertion and connection of the expansion and cutting components, which also facilitates the replacement of the cutting components.

[0057] The purpose of setting the groove is to cooperate with the cutting component. By gradually changing the depth of the groove, the spacing of the water ripples can be changed. The expansion tire elastic component has a variety of specifications that can be changed according to the different groove depths, and is suitable for processing water ripples with different spacings.

[0058] like Figure 1 , 3 As shown, in order to illustrate the specific structure of the locking assembly, the present invention uses the locking assembly 6, which includes: a plurality of holes 61, which are opened at the tool holder 1 and located on the side corresponding to the cutting assembly 2; and a locking member 62, which is threadedly connected to the holes 61, and whose end abuts against the side of the water ripple knife 21.

[0059] In this solution, by rotating the locking component, the end of the locking component abuts against the side of the water-pattern cutter, thus restricting the movement of the water-pattern cutter and locking the handle and the chip assembly.

[0060] like Figure 3 As shown, in order to further lock the water ripple cutter, the present invention employs a V-groove 212 on the side of the water ripple cutter 21 along its movement direction; the end of the locking member 62 has a tapered part 621 that is adapted to the V-groove 212.

[0061] When the tapered part contacts the V-groove, the tool holder and the chip assembly are locked together; when the tapered part does not contact the V-groove, the chip assembly can only move linearly along the length of the V-groove due to the limiting effect of the tapered part.

[0062] like Figure 3 As shown, in order to illustrate the reset after the tire expands outward, this utility model uses a reset retaining ring 7 at the center of the expanded tire 3;

[0063] When the pressing part 3 is rotated upward, the wedge-shaped part 4 gradually reduces the force on the expanded tire 5 until it is rotated out to the point where it abuts the reset retaining ring 7. Then, the pressing part 3 transmits the force to the wedge-shaped part 4 through the retaining ring 7, causing the wedge-shaped part 4 to move upward synchronously until the expanded tire is completely reset.

[0064] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
