Description

Technical Field

[0001] The invention relates to the technical field of cutting tool manufacturing, in particular to a hole position measuring device for indexable inserts, and also specifically to a hole position measuring method. Background Art

[0002] The indexable insert includes multiple cutter heads that are ground and formed. The front and rear angles of the cutting edge are formed by the combination of the cutter head and the tool bar groove. During use, when a cutting edge becomes blunt, it can be quickly indexed and the adjacent new cutting edge can be replaced with the main cutting edge to continue working. The blades are not removed until all the cutting edges are blunt, and then replaced with new blades to continue working. The frequency of tool replacement can be reduced and production efficiency can be improved. However, the inventors found the following problems in the process of manufacturing indexable inserts:

[0003] Due to the limitations of existing manufacturing equipment, the position of the mounting hole of the indexable insert is prone to deviation during the powder pressing stage, sintering stage and finishing stage of the existing production process, resulting in deviations in the size of the mounting hole to the edges of the insert. At present, as more and more indexable inserts are fixed to the tool bar by screws, the position of the mounting hole on the insert is becoming more and more important. If the size of the mounting hole to the edges of the insert is too large, after the blade and the tool bar are installed, the fit between the various cutting heads on the blade and the tool bar groove will decrease, making it difficult for the cutting edge formed by the combination to perform cutting actions, or the blade and the tool bar groove are not tightly fitted, causing the blade to shake. Therefore, during the manufacturing process, it is necessary to ensure that the deviation of the size of the mounting hole to the edges of the blade meets the manufacturing requirements.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0056] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0057] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0058] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0060] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0061] The indexable insert is equipped with at least two cutter heads. When one of the cutter heads is severely worn, the adjacent cutter head can be indexed to continue working as the main cutter. When the cutter heads on the indexable insert are blunt, the cutter heads are removed and scrapped for recycling, and then replaced with new cutters to continue working. The indexable insert can avoid the defects of welding and mechanical clamping cutters caused by welding and re-grinding. There is no need to sharpen or change the cutter, the cutting performance is stable, and the production efficiency and quality are greatly improved. It is one of the cutters currently being promoted and applied in my country.

[0062] However, when manufacturing indexable inserts, the position of the mounting hole of the insert is not taken seriously. Specifically, the defects in the manufacturing process of the insert include: (i) the indexable insert is affected by the mold assembly gap during the powder pressing stage and the position deviation of the mounting hole is not taken seriously; (ii) the mounting hole is deformed during the sintering process of the insert, resulting in dimensional deviations between the mounting hole and the edges; (iii) the mounting hole is generally not selected as a reference for positioning during the finishing process, resulting in excessive position deviations between the mounting hole and the convertible reference surface. As more and more tool bars and discs are connected to indexable inserts by screws to achieve fixed installation. The gap between the mounting hole and the tool bar and disc is fixed. Once the deviation of the mounting hole on the indexable insert is too large, when the indexable insert is installed, the side with the smaller size of the mounting hole and the reference surface will not be able to fit tightly with the tool bar and disc reference surface, resulting in the blade still shaking after the screws are tightened. The side with the larger size of the mounting hole and the reference surface will cause the screws to fail to tighten normally.

[0063] In order to timely detect excessive deviation of the mounting hole on the indexable insert during the manufacturing process. Figure 1 , 2 , Figure 1 is a schematic diagram of the three-dimensional structure of a measuring device according to some embodiments of the present application, Figure 2Schematic diagram of an explosion of a measuring device according to some embodiments of the present application. The present application provides a hole position measuring device for indexable inserts, which monitors the inserts after various manufacturing processes such as pressing, sintering, and precision grinding. The hole position measuring device includes: a base 100, a sliding assembly 200 slidably connected to the base 100, and a detection assembly 300 installed on the sliding assembly 200. Among them, the base 100 is provided with a pin 13 for connecting the mounting hole on the indexable insert. Driven by the sliding assembly 200, the detection assembly 300 moves along the first straight line a located on one side of the pin 13. The detection assembly 300 includes a detection head 31 and an adjustment element 33 driving the detection head 31. Driven by the adjustment element 33, the detection head 31 moves along the first straight line a. The detection assembly 300 can accurately read the distance data parameters of the adjustment element 33 adjusting the detection head 31.

[0064] In this solution, the pin 13 is located in the direction of the first straight line a, and the sliding assembly 200 is at one side of the pin 13, and the detection assembly 300 moves along the first straight line direction on one side of the pin 13. The pin 13 is connected to the base 100. The mounting hole of the indexable blade is sleeved on the pin 13, so that the indexable blade is rotatably connected to the pin 13. At the same time, since the indexable blade is sleeved on the pin 13, other connection relationships are omitted, and thus, the indexable blade can be quickly disassembled and assembled, so that the blade can be placed in the hole position measuring device for measurement after each manufacturing process to ensure the accuracy of the mounting hole position.

[0065] Under the action of external force, the sliding assembly 200 moves along the first straight line a, and the adjusting element 33 drives the detection head 31 to move along the first straight line a, so that the sliding assembly 200 and the detection head 31 move along the same straight line. Driven by the sliding assembly 200 and the adjusting element 33, the detection head 31 is close to the edge of the indexable insert. In a specific embodiment, the detection assembly 300 is a differential head. During the measurement process of the hole position measurement device, the sliding assembly 200 first drives the detection assembly 300, so that the detection head 31 is close to the edge of the indexable insert, and a certain gap is ensured between the detection head 31 and the edge. The detection head 31 is driven by the adjusting element 33 to move the gap distance until the detection head 31 contacts the edge of the insert. The detection head 31 is driven by the sliding assembly 200 to move a large distance. Then, the detection head 31 is driven by the adjusting element 33 to fine-tune the data parameters obtained to compare the deviations between different heads on the same indexable insert. Since the hole position measuring device will be suitable for indexable tools of different sizes, the adjustment element 33 drives the detection head 31 to adjust a small range of distances. Therefore, the sliding component 200 is used to drive the detection head 31 to transfer within a larger distance range, making way for the blade to facilitate the installation of the blade. Since the sliding component 200 has a large amplitude to adjust the distance, it is difficult to control the distance accuracy when transferring the distance. Therefore, the sliding component 200 greatly reduces the distance between the detection head 31 and the indexable blade. And then the adjustment element 33 is used for small-amplitude fine-tuning. The small step of the adjustment element 33 to adjust the detection head 31 can adjust the distance more accurately, and the specific distance parameters must be read out after the adjustment element 33 adjusts the detection head 31. According to the specific parameters, the distance deviation data of each side of the tool head can be conveniently calculated, which is more convenient to judge whether the position of the mounting hole on the indexable blade meets the manufacturing requirements. However, the small step of the corresponding adjustment element 33 will result in more time spent on adjusting the same distance and lower efficiency. In this solution, the detection head 31 is driven by the sliding assembly 200 and the adjustment element 33, which takes into account both the high efficiency of large-scale transfer and the high precision of small-scale movement, and facilitates accurate monitoring of the position of the mounting hole of the indexable insert during the manufacturing process.

[0066] In some embodiments of the present application, the base 100 includes a base 11, and the base 11 includes a first plate portion and a second plate portion. The second plate portion extends outward from the side of one end of the first plate portion to form an L-shaped base 11; the sliding component 200 is slidably connected to the first plate portion, and the pin shaft 13 is installed on the end surface of the second plate portion. When the sliding component 200 slides along the direction of the first straight line a, the detection component 300 moves toward the second plate portion.

[0067] The second plate portion is a boss located at one end of the first plate portion, and the pin 13 is installed on the second plate portion. The receiving platform of the blade is raised by the second plate portion, so that the detection head 31 of the detection component 300 located on the same side of the first plate portion can measure the blade accordingly. Since the detection head 31 of the detection component 300 is installed on the sliding component 200, there is a height difference between the detection head 31 and one side of the first plate portion; if the second plate portion as a boss is not provided, when the blade is received on the base 11, the blade will be attached to one side of the first plate portion. It will be difficult for the detection head 31 to measure the edge of the blade. On the other hand, the second plate portion is located on the moving path of the sliding component 200, and the movement of the sliding component 200 can be stopped by the second plate portion, limiting the distance that the detection head 31 moves toward the pin 13. It is effective to avoid the collision between the detection head 31 and the pin 13 due to interference, thereby causing damage to the detection head 31 and / or the pin 13.

[0068] Furthermore, the pin 13 uses cemented carbide as a substrate and is surface coated, which increases the wear resistance of the pin 13 and reduces the wear caused by the friction between the indexable blade and the pin 13 during use, thereby effectively increasing the service life of the pin 13.

[0069] In some embodiments of the present application, further, the other end face of the first plate portion opposite to the second plate portion is the first end face 111; a slide groove 113 is provided on the first plate portion, and the slider 24 on the sliding assembly 200 is located in the slide groove 113. The slide groove 113 extends along the first straight line a to the first end face 111 and forms an opening on the first end face 111. A receiving plate 14 is installed on the first end face 111, and the receiving plate 14 is located on the opening, and the receiving plate 14 is used to stop the slider 24 of the sliding assembly 200.

[0070] The receiving plate 14 is fixedly connected to the first end surface 111 by screws, and the receiving plate 14 blocks the opening to limit the slider 24 from being separated from the slide groove 113 from the opening. More specifically, the cross-sectional shape of the slide groove 113 is an inverted T-shaped space. The cross-sectional shape of the slider 24 is consistent with or partially consistent with the cross-sectional shape of the slide groove 113, so that the slider 24 is limited by the slide groove 113 and slides along the extension direction of the slide groove 113, that is, the first straight line a.

[0071] The opening of the slide groove 113 is provided at the first end surface 111, so that the hole position measuring device can be easily assembled, and the slider 24 can be easily installed into the slide groove 113 from the opening. In addition, after the slider 24 is installed, the opening is blocked by the receiving plate 14 to prevent the slider 24 from falling out of the opening, and the receiving plate 14 and the second plate portion can conveniently limit the sliding distance of the sliding assembly 200.

[0072] In some embodiments of the present application, Figure 2 As shown, further reference Figure 4 , Figure 4 The schematic diagram of the partial structure of the measuring device according to some embodiments of the present application. The receiving plate 14 receives the adjusting part 23 for adjusting the sliding assembly 200; one end of the adjusting part 23 is connected to the base 11 through a thread, and the adjusting part 23 is rotated forward / reversely, and the sliding assembly 200 is limited by the slide groove 113 to reciprocate along the first straight line a.

[0073] A threaded portion 233 is provided at one end of the adjusting portion 23, and a threaded hole is opened at a corresponding position on the base 11. The threaded portion 233 is connected to the threaded hole for transmission. When the adjusting portion 23 is rotated, the sliding assembly 200 slides along the direction of the first straight line a, so as to achieve the fixing of the sliding assembly 200 at any position within the sliding distance range.

[0074] In some embodiments of the present application, a receiving groove 141 is provided on the upper surface of the receiving plate 14, and the adjusting portion 23 includes a limiting portion 232, which is embedded in the receiving groove 141; the limiting portion 232 is embedded in the receiving groove 141 to limit the position of the adjusting portion 23 in the direction of the first straight line a. The adjusting portion 23 also includes a hand-held portion 231; wherein the hand-held portion 231 is in the shape of a flat disk, and a notch is provided on the circumference of the hand-held portion 231 to increase friction, and the hand-held portion 231 is convenient for the operator to hold. The hand-held portion 231 is located at the other end of the adjusting portion 23 away from the base 11, and the limiting portion 232 is arranged close to the hand-held portion 231.

[0075] The receiving groove 141 is formed with an opening on the upper surface of the receiving plate 14, so that the limiting portion 232 can be inserted into the receiving groove 141 from the opening on the upper surface. The outer surfaces of both ends of the limiting portion 232 extend outward to form bosses, so that the cross-sectional outer contour of the limiting portion 232 is in the shape of an industrial line. The bosses on both sides of the limiting portion 232 fit on the two side surfaces of the receiving groove 141 to limit the movement of the adjusting portion 23 in the direction of the first straight line a. More specifically, referring to Figure 5 , Figure 5 for Figure 4 A partial enlarged schematic diagram of the center A. The receiving groove 141 includes a first groove 1411 and a second groove 1412 which are arranged concentrically. The first groove 1411 and the second groove 1412 form a stepped receiving groove 141. The cross-sectional area of ​​the first groove 1411 is smaller than the cross-sectional area of ​​the second groove 1412, and the boss on one side of the limiting portion 232 is received in the second groove 1412.

[0076] The user can hold the handheld portion 231 and rotate the handheld portion 231 to drive the adjusting portion 23 to rotate, thereby providing an external force to drive the sliding assembly 200 to slide. Under the transmission of the threaded portion 233 and the threaded hole, the rotational motion is converted into a linear motion of the sliding assembly 200.

[0077] In some embodiments of the present application, reference Figure 3 , Figure 3 Schematic diagram of the three-dimensional structure of the sliding assembly in the measuring device according to some embodiments of the present application. The sliding assembly 200 includes a receiving seat 21 and a slider 24, and the slider 24 is connected to the bottom of the receiving seat 21. The receiving seat 21 is provided with a mounting position for the detection assembly 300, and the detection assembly 300 is installed at the mounting position and limited to the receiving seat 21.

[0078] Specifically, the receiving seat 21 includes a first extension portion 211 and a second extension portion 212. The second extension portion 212 is located on the first plate portion, and the first extension portion 211 extends upward in a vertical direction from the side of the second extension portion 212. The mounting position is provided on the first extension portion 211, and more specifically, the mounting position is a hole position, and the detection component 300 is inserted into the mounting position so that the detection component 300 is supported on the receiving seat 21 by the mounting position. The detection head 31 passes through the mounting position and extends from the side of the first extension portion 211 close to the second plate portion.

[0079] In this solution, the second extension portion 212 includes a plate-shaped member 2121 and a connecting block 2122. The plate-shaped member 2121 is attached to the side of the first plate portion. The connecting block 2122 is located at the bottom of the plate-shaped member 2121. The connecting block 2122 and the plate-shaped member 2121 form a T-shaped second extension portion 212. The connecting block 2122 extends into the slide groove 113. The connecting block 2122 is connected to the slider 24 so that the second extension portion 212 is limited in movement direction by the slide groove 113.

[0080] In some embodiments of the present application, further, the detection assembly 300 is fixed on the receiving seat 21 through a clamping portion 22. The receiving seat 21 is provided with a clearance opening 2111 as a mounting position, and the clamping portion 22 controls the gap size in the clearance opening 2111 so as to clamp and fix the detection assembly 300 by closing the two inner walls of the clearance opening 2111.

[0081] The clearance opening 2111 includes a gap and a hole. The clamping part 22 drives the two inner walls of the clearance opening 2111 to close inward to reduce the volume of the clearance opening 2111. By reducing the volume of the clearance opening 2111, the inner wall of the hole is pressed against the detection component 300. Specifically, the gap extends to the inner wall of the hole, so that the inner wall of the hole has a C-shaped profile. The clamping part 22 is a screw, and the clamping part 22 connects the two inner walls of the gap. By turning the screw, the gap distance is reduced, thereby driving the hole to be reduced.

[0082] Furthermore, a sleeve 25 is embedded in the hole, and the sleeve 25 is a C-shaped elastic block, and the detection component 300 passes through the sleeve 25. When the inner wall of the hole is compressed, the sleeve 25 is forced to press the detection component 300. Since the sleeve 25 is an elastic block, it elastically deforms under the reverse force of the rigid inner wall of the hole and the detection component 300, thereby tightening the detection component 300 by elastic force. Because the sleeve 25 is an elastic block, the deformation of the sleeve 25 during extrusion prevents the rigid inner wall of the hole from directly contacting and extruding the rigid detection component 300, thereby damaging the detection component 300.

[0083] In some embodiments of the present application, Figure 2 As shown, one end of the base 100 where the pin shaft 13 is installed is the second end surface 112 ; the second end surface 112 is connected to the gasket 12 , and part of the pin shaft 13 passes through the gasket 12 and extends to the outside of the gasket 12 .

[0084] The second end face 112 is the upper surface of the second plate portion. Since the hole position measuring device uses different indexable blades. The thickness of various types of blades is inconsistent, and the height of the detection head 31 is relatively fixed. In order to ensure that the detection head 31 corresponds to the blade edge of various types of blades, gaskets 12 of different heights can be detachably connected on the second end face 112 to facilitate the adjustment of the height of various types of blades so that the blade height adapts to the height of the detection head 31. On the other hand, the hole position measuring device needs to rotate the blade when measuring the blade. If the blade directly contacts the second plate portion, the blade will wear the second plate portion after long-term use, thereby causing the surface quality of the second plate portion to deteriorate, and when replacement is required, the base 11 needs to be replaced in its entirety, which is costly. In the present embodiment, by arranging the gasket 12 on the second end face 112, the blade is in contact with the gasket 12, and the gasket 12 is small in size and easy to disassemble and assemble, which can reduce the maintenance cost.

[0085] Furthermore, a protruding block 121 extending upward is provided on the upper surface of the gasket 12, and the pin 13 extends from the protruding block 121. The protruding block 121 reduces the contact area between the gasket 12 and the cutter head, thereby reducing friction. At the same time, the protruding block 121 is provided at the center of the gasket 12 to raise the cutter head to prevent the cutting edge from directly contacting the gasket 12 and damaging the gasket 12.

[0086] In some embodiments of the present application, the present application further provides a hole position measurement method, which is applicable to the hole position measurement device provided in the above embodiments, the indexable insert includes at least two tool heads, and the measurement method includes:

[0087] The position of the detection head 31 is adjusted via the adjustment element 33, the detection head 31 locates the position of the first cutting head in the indexable insert, and the detection component 300 reads the first distance of the first cutting head;

[0088] After obtaining the first distance, the indexable insert is rotated around the axis of the pin shaft 13 until the second cutter head in the indexable insert corresponds to the detection head 31, the detection head 31 locates the position of the second cutter head, and the detection component 300 reads the second distance of the second cutter head;

[0089] The distance deviation between the second cutter head and the axis of the pin shaft 13 is calculated based on the first distance and the second distance, and whether the distance between the second cutter head and the axis of the pin shaft 13 meets the manufacturing requirements is determined based on the distance deviation.

[0090] If the number of indexable insert heads is greater than two, the indexable insert is rotated to the detection head 31 corresponding to the Nth insert head. The detection head 31 locates the position of the Nth insert head. The detection component 300 reads the Nth distance of the Nth insert head. It is determined whether the Nth insert head meets the manufacturing requirements based on the first distance and the Nth distance.

[0091] It should be noted that, in order to ensure the consistency of detection, the detection head 31 corresponds to the same position of each cutter head. Preferably, the detection head 31 corresponds to the cutting edge position, and the cutting edge of the cutter head is the farthest point from the axis of the pin 13 to the cutter head of the indexable insert. The cutting edge of the cutter head is detected by the detection head 31 to determine whether the position of the mounting hole is located at the center position.

[0092] The method for determining whether the Nth tool head meets the manufacturing requirements includes: determining whether the difference between the distance of the corresponding tool head measured by the detection head 31 and the distance of the first tool head measured by the detection head 31 is within the allowable error range; if so, determining that it is qualified; if not, determining that it is unqualified.

[0093] The distance measured by the detection head 31 for each cutter head is compared with the distance measured by the detection head 31 for the first cutter head, and the distance measured by the detection head 31 for the first cutter head is used as a reference to determine whether the mounting hole to the cutting edges on the blade are consistent, and further determine whether the processed blade meets the manufacturing requirements.

[0094] In some embodiments of the present application, the method for the detection component 300 to read the distance deviation between the first cutting head and the second cutting head further includes:

[0095] Before measuring, the detection assembly 300 is reset to zero, and the sliding assembly 200 drives the detection assembly 300 to bring the detection head 31 into contact with the cutting edge of the first cutting head in the indexable insert; at this time, the sliding assembly 200 is fixed to limit the movement of the sliding assembly 200;

[0096] The indexable insert is rotated until the cutting edge of the second cutter head corresponds to the detection head 31, and the detection head 31 is adjusted to contact the cutting edge of the second cutter head. The distance adjusted by the adjustment element 33 is the distance deviation between the first cutter head and the second cutter head.

[0097] The detection assembly 300 also includes a reading window 32, which can display the mechanism detected by the detection head 31. The sliding assembly 200 can be fixed by the threaded portion 233 to limit the movement of the sliding assembly 200. According to the data displayed in the reading window 32 when the detection head 31 detects different tool heads, the deviation between each tool head and the first tool head can be intuitively displayed, thereby facilitating the user to judge whether the processed blade meets the manufacturing requirements. The omission of the calculation step makes the measurement process faster and improves the detection efficiency.

[0098] In some embodiments of the present application, reference Figure 6 , Figure 6 It is a front view of the measuring device according to some embodiments of the present application. The detection head 31 includes a contact surface 311 in contact with the cutter head. The contact surface 311 and the cutting edge surface of the cutter head adopt the contact method of an arc surface and a plane, that is, if the cutting edge surface of the cutter head is an arc surface, then the contact surface 311 is a plane. When the cutting edge surface of the cutter head is a plane, the contact surface 311 is replaced by an arc surface. The working principle that the highest point of contact between the arc surface and the plane is always used to avoid multiple contact points that affect the detection results. Accurately measure the cutting edge in the indexable insert.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
