Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tool crystal welding, and in particular to a tool crystal welding adjusting and positioning device and method. BACKGROUND

[0002] In the field of modern high-precision machining and manufacturing, the demand for micron-level or even nanometer-level machining precision puts extremely high requirements on the welding precision of tool crystals. Super-hard crystal materials (such as diamond and cubic boron nitride) are widely used in high-precision cutting tool crystals due to their excellent hardness, wear resistance and thermal stability. However, the particularity of such materials (such as anisotropy and high thermal sensitivity) poses great challenges to their welding process.

[0003] During the welding process of tool crystals, the anisotropy of crystal materials requires precise control of the orientation of the crystal during welding to ensure the optimal cutting performance of the tool crystal (for example, matching the cleavage plane of the crystal with the cutting direction, thereby reducing the cutting resistance and improving the service life of the tool crystal). In addition, modern multi-axis machining (such as five-axis machine tools) requires the tool crystal to work stably at different inclination angles, so the spatial posture of the crystal needs to be adjusted in advance during welding to meet the needs of complex machining scenarios.

[0004] Patent CN115740877B discloses a diamond automatic welding frame, which includes a lifting assembly for adjusting the up-down movement of the device, a sliding sleeve is fixedly connected to the outer wall of the hydraulic rod on both sides, and the sliding sleeve is slidably connected to the inside of the sliding sleeve; a sliding assembly for adjusting the left-right movement of the device to change the processing position of the bottom, which is composed of a mounting groove, an adjusting block and a moving rod, and the moving rod is arranged in the inside of the adjusting block and at the bottom end of the mounting groove; a fixed frame is installed with a clamping assembly in the inside of the fixed frame, and the fixed frame is provided with a fixed frame on both sides of the outer wall, and the fixed frames are connected by connecting rods. The patent adjusts the tool crystal up and down through the lifting assembly and adjusts the tool crystal left and right through the sliding device.

[0005] Patent CN109158748B discloses a polycrystalline diamond machine clamp blade high-frequency induction automatic welding device, which includes a base, a lead screw sliding table, a support seat and a turntable. The turntable includes a work station disc and a tool holder, four dovetail grooves are evenly arranged on the bottom end of the work station disc, and a movable tool holder is arranged in each dovetail groove. The head structure of the tool holder can not only adjust and position the polycrystalline diamond composite piece, but also apply downward pressure to it.

Therefore, a new type of welding tool that can realize multi-degree-of-freedom precise adjustment and adjust the spatial posture of the tool crystal according to the crystal orientation is needed.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0065] As described in the background, in the field of modern high-precision machining and manufacturing, the demand for micron-level or even nanometer-level machining precision puts forward very high requirements on the welding precision of tool crystals. In order to solve the technical problems that the existing superhard crystal material welding tooling has single adjustment capability and is difficult to adjust the spatial pose of the tool crystal according to complex machining scenes, in one aspect of the present application, a kind of adjusting and positioning device for tool crystal welding is provided, referring to Figures 1 to 9 which includes a supporting plate 1 and a planar adjusting mechanism 3 on the upper side thereof. Among them, the supporting plate 1 as the core bearing platform integrates the components of the planar adjusting mechanism 3, which supports the to-be-welded blade 32 and ensures the spatial pose stability of the tool crystal 4. The planar adjusting mechanism 3 is suitable for adjusting the position of the to-be-welded blade 32 and the tool crystal 4 as a whole and between them in the horizontal plane, to adapt to the size, shape and material of different to-be-welded blades 32 and tool crystals 4, and the requirements of welding process, etc.

[0066] Specifically, in the exemplary embodiment, the planar adjustment mechanism 3 comprises a rotating plate 31, a blade to be welded 32, a positioning assembly 33, a position adjustment assembly and a fixing assembly. Among them, the rotating plate 31 serves as the movement platform of the planar adjustment mechanism 3, and changes the horizontal orientation of the blade to be welded 32 by rotating itself; the blade to be welded 32 directly carries the tool crystal 4 and is finally welded and fixed with the tool crystal 4, and is the final carrier for all spatial attitude adjustments of the tool crystal 4; the positioning assembly 33 realizes accurate control of the position of the blade to be welded 32 in the horizontal plane through the precise movement of the driving slider in the orthogonal direction; the position adjustment assembly is suitable for pushing and adjusting the relative position of the tool crystal 4 and the blade to be welded 32, so as to realize the accurate welding of the two after the adjustment is completed; the fixing assembly stably presses the tool crystal 4 against the blade to be welded 32 from one side to prevent displacement of the tool crystal 4 during welding.

[0067] Specifically, in the exemplary embodiment, the rotating plate 31 is rotationally connected with the supporting plate 1 through a rotating adjustment piece. The rotating adjustment piece is not only used to transmit torque to drive the rotating plate 31 to rotate, but also integrates high-precision angle measurement and fine adjustment functions to realize accurate adjustment of the planar orientation of the blade to be welded 32 and the tool crystal 4, so as to better align with the fixing assembly. When the fixing assembly exerts pressure on the tool crystal 4, the tool crystal 4 can be stably and uniformly stressed to be tightly pressed against the blade to be welded 32. Further, the rotating adjustment piece comprises a connecting shaft 361, a differential knob (not shown) and a gear 363.

[0068] Further, the connecting shaft 361 is made of stainless steel material and is precisely ground to ensure that it has very high coaxiality and rotation accuracy. The connecting shaft 361 is rotationally connected and axially fixed with the rotating plate 31 through a pair of high-precision angular contact bearings to ensure smooth transmission. The upper end of the connecting shaft 361 is suitable for fixed connection with the differential knob, and the lower end is suitable for fixed connection with the gear 363.

[0069] Further, the outer circumference of the differential knob is treated with knurling to increase the friction force for fine operation. The end face is provided with circumferential scale lines, for example, divided into 120 sections, and the rotating plate 31 is provided with a fixed zero position indicating mark which cooperates with the scale of the differential knob to read the value. The differential knob and the connecting shaft 361 are coaxially fixed through interference fit. The scale value of the differential knob and the transmission ratio of the gear 363 and the arc-shaped rack 364 driven thereby are precisely designed correspondingly. For example, when the design is that one complete rotation (360°) of the differential knob corresponds to 1° rotation of the rotating plate 31, each scale section on the knob corresponds to 0.0083° (30 seconds) rotation of the rotating plate 31, thereby realizing high-resolution angle adjustment.

[0070] Further, the gear 363 is fixed to the lower end of the connecting shaft 361, and a small modulus (e.g. 0.5 modulus) precision spur gear 363 is adopted, and the tooth surface is quenched and ground to ensure wear resistance and transmission accuracy.

[0071] Further, an arc-shaped clearance hole 11 is formed on the support plate 1, which is a circular arc-shaped through hole with a width slightly larger than the addendum circle diameter of the gear 363, and the arc length determines the maximum rotatable angle range of the rotating plate 31 (e.g. ±30°). The arc-shaped clearance hole 11 not only provides a movement trajectory space for the gear 363, but also serves as the installation base of the arc-shaped rack 364. The arc-shaped rack 364 is fixedly installed on the hole wall of the arc-shaped clearance hole 11 formed on the support plate 1. The arc-shaped rack 364 has the same modulus as the gear 363, and the tooth shape center coincides with the rotation center of the rotating plate 31.

[0072] The rotating adjusting member is essentially a speed reduction fine adjustment mechanism that converts rotary motion into precise angular displacement. The working principle is that the operator rotates the differential knob exposed above the rotating plate 31, which drives the lower end gear 363 to rotate through the connecting shaft 361, and the gear 363 is engaged with the arc-shaped rack 364 fixed on the support plate 1. Due to the transmission ratio of the gear 363 and the arc-shaped rack 364 and the fine scale of the differential knob, the operator's large-amplitude rotary motion is converted into extremely small and precise angular displacement of the rotating plate 31. The rotating adjusting member enables the operator to adjust the horizontal orientation of the tool crystal 4 with micron-level precision, and cooperates with the positioning assembly 33 and the position adjusting assembly to realize precise adjustment of the spatial posture of the tool crystal 4, ensuring accurate alignment of the welding position of the tool crystal with the to-be-welded surface of the tool handle.

[0073] Specifically, in the exemplary embodiment, to realize precise positioning of the to-be-welded blade 32 in any direction in the plane of the rotating plate 31 and prevent it from moving beyond the range, a limiting structure is provided on the rotating plate 31, which can allow independent and composite motion of the to-be-welded blade 32 in two orthogonal directions in the horizontal plane and ensure controllability of the motion range.

[0074] Further, the limiting structure includes a limiting rod and a limiting plate. The limiting rod is preferably a hard alloy cylindrical pin, one end of which is fixed perpendicularly to the lower surface of the to-be-welded blade 32 by threads. Therefore, the position of the limiting rod directly represents the position of the to-be-welded blade 32, and the to-be-welded blade 32 can be replaced.

[0075] Further, the inside of the rotating plate 31 is formed with a cavity by machining, which is located directly below the limiting rod. The limiting plate is placed in the cavity, and its cross-sectional shape matches that of the cavity (usually rectangular), so that the limiting plate can slide in the X and Y directions in the cavity. Further, the upper surface of the rotating plate 31 is provided with a limiting hole that communicates with the cavity. The limiting hole is designed as a rectangular hole or an oval hole that is slightly larger than the diameter of the limiting rod in the X-Y direction. The length of the hole in the X direction defines the maximum allowable stroke of the welding blade 32 in the X direction, and the length in the Y direction defines the maximum allowable stroke in the Y direction.

[0076] Further, the end of the limiting rod away from the welding blade 32 passes through the limiting hole in the rotating plate 31 and is fixedly connected with the limiting plate in the cavity by screw threads. Therefore, the limiting plate and the welding blade 32 are rigidly connected through the limiting rod, and the movements of the two are completely synchronized.

[0077] When the welding blade 32 moves within the normal range, the limiting rod moves freely in the limiting hole. When the welding blade 32 moves to the limit position, the limiting rod will contact the hole wall of the limiting hole. Since the limiting rod is rigidly connected with the limiting plate and the welding blade 32, this contact will produce a direct mechanical interference, preventing the welding blade 32 from moving further in that direction.

[0078] Specifically, in the exemplary embodiment, the positioning assembly 33 is formed as a two-stage sliding table mechanism, and its core function is to accurately transmit linear motion in two directions to the welding blade 32. The positioning assembly 33 specifically includes a first sliding block 331, a first sliding adjustment member 332, a second sliding block 333, and a second sliding adjustment member 334.

[0079] Further, the upper surface of the rotating plate 31 is fixedly installed with two parallel transverse sliding shafts 311 by two precision pressing plates. The transverse sliding shafts 311 are made of quenched and polished steel, have very high straightness, surface finish, and hardness, and their axes define the first direction (X axis). The bottom of the first sliding block 331 is machined with a first sliding hole that accurately matches the transverse sliding shaft 311. A linear bearing or a self-lubricating bronze bushing is pressed into the first sliding hole, so that the first sliding block 331 can smoothly slide along the transverse sliding shaft 311 without shaking, while minimizing sliding friction.

[0080] Further, the first sliding block 331 is fixedly installed with two parallel longitudinal sliding shafts 3311 in the same way. The axes of the longitudinal sliding shafts 3311 are strictly orthogonal to the transverse sliding shaft 311, defining the second direction (Y axis). The second sliding block 333 is formed with a second sliding hole by machining, and a linear bearing or a bushing is also installed in the hole, so that it can slide along the longitudinal sliding shaft 3311.

[0081] Further, the first sliding adjustment member 332 and the second sliding adjustment member 334 are both tail-adjusting micrometers, which are rigidly fixed on the rotating plate 31 through a fixed clamp. The fixed clamp can constrain the radial and axial movement of the micrometer body, and only allow the micrometer to rotate, so that the transmission axis of the pushing force is consistent with the movement direction, and the lateral force is avoided.

[0082] Further, in order to realize the reliable driving connection between the telescopic rod of the second sliding adjustment member 334 and the second sliding block 333, and ensure the smoothness of the movement decoupling, the end structure of the telescopic rod is specially designed. The end of the telescopic rod of the second sliding adjustment member 334 (tail-adjusting micrometer) is machined to have a circumferential groove. The circumferential groove is turned around the circumference of the telescopic rod, so that the diameter of the part where the circumferential groove is located is significantly smaller than the diameter of the telescopic rod body and other parts, thereby forming a narrow neck part. At the same time, a third sliding hole is formed on the second sliding block 333 along the first direction (X-axis), and the narrow neck part is directly inserted into and clamped in the third sliding hole on the second sliding block 333.

[0083] Specifically, the diameter of the third sliding hole is slightly larger than the diameter of the narrow neck part of the telescopic rod, so that the narrow neck part can smoothly slide in the hole along the first direction (X-axis) without jamming. At the same time, the diameter of the third sliding hole is smaller than the diameter of the telescopic rod body, so that the telescopic rod body cannot enter the third sliding hole. When the telescopic rod of the second sliding adjustment member 334 is driven to extend along its axial direction, the side end face of the circumferential groove on the telescopic rod close to the body will abut against the hole end face of the third sliding hole. The axial pushing force of the telescopic rod is effectively transmitted to the second sliding block 333, pushing it to slide in the second direction. When it is retracted, it is pulled by the end face on the other side of the circumferential groove. When the first sliding block 331 pushes the second sliding block 333 to move in the first direction (X-axis), the narrow neck part of the telescopic rod of the second sliding adjustment member 334 slides in the third sliding hole, and does not interfere with the movement of the second sliding block 333 in the first direction. Compared with the traditional component stacking method, such arrangement can greatly improve the compactness of the device, avoid structural bulkiness, and significantly enhance the reliability of the device. At the same time, this structure perfectly absorbs the displacement caused by the movement of the first sliding block 331, completely eliminates the interference and internal stress between different movement directions, ensures the smoothness of the fine adjustment process, and makes the entire positioning assembly 33 have high running stability and long-term precision retention.

[0084] Specifically, in the exemplary embodiment, the blade 32 to be welded is a piece of precisely ground rhombic cemented carbide, with an edge groove machined on one side edge, which is suitable for accommodating the tool crystal 4. A V-shaped opening corresponding to the shape of the blade 32 to be welded is formed on the second sliding block 333, and the blade 32 to be welded is clamped in the V-shaped opening, so that the blade 32 to be welded can be carried by the second sliding block 333 to move in the first direction and the second direction.

[0085] Specifically, in the exemplary embodiment, the positioning assembly is used to push the tool crystal 4 out of the edge groove of the blade 32 to be welded by a preset distance to reach the welding position before the fixing assembly tightly abuts the tool crystal 4. Further, the positioning assembly includes a third telescopic adjusting member 351 and an abutting member 352.

[0086] Further, the third telescopic adjusting member 351 is the driving source of the ejection action, which adopts a tail-adjusting micrometer, and the third telescopic adjusting member 351 is fixedly installed on the rotating plate 31 through a fixing bracket.

[0087] Further, the abutting member 352 is a component directly performing the pushing function, and the abutting member 352 is a flat plate made of rigid material. One end of the abutting member 352 is fixed on the telescopic rod of the third telescopic adjusting member 351 through a plurality of fine bolts, and the other end of the abutting member 352 abuts against the end of the tool crystal 4 along the edge groove of the blade 32 to be welded, and thereby pushes the tool crystal 4 to be positioned in the edge groove of the blade 32 to be welded. In actual application, according to the size and shape of the tool crystal 4 and the blade 32 to be welded, and the structure of the surrounding components, the abutting member 352 is selected to perform the pushing function of the tool crystal 4 and prevent interference and friction with other components.

[0088] Specifically, in the exemplary embodiment, the fixing assembly is used to stably and reliably abut and fix the tool crystal 4 on the blade 32 to be welded after the spatial posture adjustment of the tool crystal 4 is completed, so as to prevent displacement in the subsequent welding operation. Further, the fixing assembly includes a second telescopic adjusting member 341 and an abutting head 342.

[0089] Further, the second telescopic adjusting member 341 is the driving source of the abutting force, which can specifically adopt a tail-adjusting micrometer or a digital micrometer, and the second telescopic adjusting member 341 is adjustably fixedly installed on the edge position of the supporting plate 1 through a fixing support.

[0090] Further, the abutting head 342 is a component directly performing the abutting function, and the abutting head 342 is detachably connected with the end of the second telescopic adjusting member 341, which can meet the welding requirements of the cutting tool crystal of more sizes and shapes. Under the action of the positioning assembly 33 and the adjusting assembly, the to-be-welded blade 32 and the cutting tool crystal 4 are basically positioned on the rotating plate 31. The rotating plate 31 is rotated by rotating the adjusting member to be in the initial position. According to the initial position, the position of the fixing assembly on the support plate 1 is adjusted, that is, the second telescopic adjusting member 341 is moved, so that the abutting head 342 is aligned and positioned with the cutting tool crystal 4 and the to-be-welded blade 32. Then, the second telescopic adjusting member 341 is operated to move the abutting head 342 towards the cutting tool crystal 4 and abut against the cutting tool crystal 4 placed in the edge groove of the to-be-welded blade 32. Before abutting, the angle of the rotating plate 31 and the position of the fixing assembly can be further adjusted to improve the alignment of the abutting head 342 with the to-be-welded surface. It can be seen that, by rotating adjustment of the rotating plate 31 and movement adjustment of the abutting head 342, the stable abutting force perpendicular to the surface of the cutting tool crystal (or the to-be-welded surface) can be accurately provided for cutting tool crystals of various sizes and shapes.

[0091] Further, the abutting part of the abutting head 342 and the cutting tool crystal 4 adopts rolling contact or flexible contact, which avoids scratching or crushing the cutting tool crystal 4 in the adjustment and abutting process.

[0092] Specifically, in the exemplary embodiment, the adjusting and positioning device can further include a space adjusting mechanism (not shown), which includes an inclination adjusting unit and a height adjusting unit, for adjusting the relative position of the abutting cutting tool crystal 4 and the to-be-welded blade 32 and the welding head.

[0093] Optionally, the inclination adjusting unit is arranged on the lower side of the support plate 1 opposite to the planar adjusting mechanism 3, and includes a bottom plate and an inclination adjusting assembly. The inclination adjusting assembly is arranged between the support plate 1 and the bottom plate to adjust the inclination direction and inclination angle of the support plate 1. Specifically, the inclination adjusting assembly includes a spherical hinge support, a plurality of first telescopic adjusting members and a rolling member. The spherical hinge support acts as a universal rotation support point, allowing the support plate 1 to incline around any axis in space, while bearing the main axial load. The plurality of first telescopic adjusting members are symmetrically distributed around the spherical hinge support, and adjust the gap between the support plate 1 and the bottom plate by telescoping, to cooperatively control the inclination angle and direction. The rolling member converts the sliding friction between the first telescopic adjusting member and the support plate 1 into rolling friction, eliminating the crawling phenomenon and prolonging the service life. Further, the spherical hinge support includes a ball head and a ball seat. The ball head is fixedly connected to the center of the lower surface of the support plate 1 to provide high-precision universal rotation support. The ball seat is fixedly installed on the bottom plate, and the inner tapered surface of the ball seat forms a self-centering fit with the ball head to ensure that the support plate 1 rotates without play during inclination adjustment. The ball seat is rigidly connected to the bottom plate by bolts.

[0094] Further, the first telescopic adjusting members adopt high-precision tail-adjusting type micrometers. There are three of them, which are installed on the bottom plate in a 120° equiangular distribution around the spherical hinge support. The three first telescopic adjusting members and the central spherical hinge support together constitute a spatial parallel mechanism. The spherical hinge support provides a central fulcrum, which constrains three translational degrees of freedom. The telescopic movement of the three first telescopic adjusting members together determines two rotational degrees of freedom (tilting direction and tilting angle) of the support plate 1 around the center of the spherical hinge. This configuration of central hinge and peripheral adjustment is the core of the realization of the universal tilting of the embodiment.

[0095] Further, the height adjusting unit is connected with the bottom plate of the tilting adjusting unit. The height adjusting unit changes the height in the vertical direction of the plane adjusting mechanism 3 and the tilting adjusting unit through a manual or automatic driving assembly. Thus, the whole set of adjusting and positioning device can cooperatively adjust the spatial posture of the tool crystal and the to-be-welded blade in multiple degrees of freedom and multiple angles in X / Y / Z directions through the coordinated operation of the plane adjusting mechanism and the spatial adjusting mechanism, so as to ensure the flexible and accurate alignment of the welding position and the welding head.

[0096] In the second aspect of the present application, an adjusting and positioning method using the above-mentioned tool crystal welding adjusting and positioning device is also proposed, which comprises the following steps:

[0097] Step 1: preliminary positioning of the to-be-welded blade in the horizontal plane

[0098] The to-be-welded blade 32 is placed on the rotating plate 31;

[0099] The differential cylinders of the first and second sliding adjusting members 332 and 334 are respectively rotated to drive the first and second sliding blocks 331 and 333 to move, so as to preliminarily position the to-be-welded blade 32 in the X and Y directions;

[0100] Step 2: preliminary positioning of the tool crystal in the horizontal plane

[0101] The tool crystal 4 to be welded is placed in the edge groove of the to-be-welded blade 32, and the differential cylinder of the third telescopic adjusting member 351 of the adjusting assembly is rotated to drive the abutting member 352 to move forward, so as to push the tool crystal 4 to slide and be preliminarily positioned in the edge groove of the to-be-welded blade 32, and ensure that the tool crystal is in good contact with the groove wall without shaking;

[0102] Step 3: precise alignment of the rotating plate and the fixed assembly in the horizontal plane

[0103] Slowly rotate the differential knob of the rotation adjusting member, finely adjust the rotation angle of the rotation plate 31 by reading the scale, move the second telescopic adjusting member 341 of the fixing assembly, and align the abutting head 342 of the fixing assembly with the to-be-welded blade 32 and the tool crystal 4; optionally, a fine adjustment step of the rotation plate 31 and the fixing assembly is further included to improve the alignment accuracy;

[0104] Step 4: Abutting and fixing of the to-be-welded blade and the tool crystal

[0105] Move the second telescopic adjusting member 341 of the fixing assembly to move the abutting head 342, and stably abut and fix the tool crystal 4 in the edge groove of the to-be-welded blade 32 to prevent the tool crystal 4 from being displaced in subsequent operations;

[0106] Optional step 5: Spatial position adjustment

[0107] Adjust the tilt direction and tilt angle of the support plate 1 through the tilt adjusting unit of the spatial adjustment mechanism, and adjust the working height of the support plate 1 through the height adjusting unit, so that the abutted tool crystal 4 and the to-be-welded blade 32 are adapted to the position of the welding head;

[0108] Step 6: Welding and combining the tool crystal 4 and the to-be-welded blade 32 by using the position-adapted welding head.

[0109] Although the preferred embodiments of the present application have been described, those skilled in the art can make further changes and modifications to the embodiments once they know the basic inventive concept. Therefore, the technical solutions of the present application are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application. Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the present application and equivalent technologies thereof, the present application also intends to include these modifications and variations.
