Description

Technical Field

[0001] The utility model relates to the technical field of measuring length, width or thickness, in particular to a PCD tool changing measuring tool. Background Art

[0002] Diamond has been used in cutting as a superhard tool material for hundreds of years. In the 1970s, people used high-pressure synthesis technology to synthesize polycrystalline diamond (PCD) to solve the problem of small quantities and high prices of natural diamonds, and expanded the application range of diamond tools to aviation, aerospace, automobiles, electronics, stone and other fields. PCD tools have the characteristics of high hardness, high compressive strength, good thermal conductivity and wear resistance, and can achieve high processing accuracy and processing efficiency in high-speed cutting. At the same time, PCD tools are replaceable, that is, after wear or chipping, they can be reused many times by replacing PCD tool heads and processing cutting edges.

[0003] like Figure 1 As shown, the PCD tool includes a tool base 10, and the end of the tool base 10 has a plurality of tool grooves 20 of different specifications for assembling PCD blades of different gears. When the cutting edge of the blade is worn or chipped, a PCD blade matching the tool groove is manufactured and processed, and then the PCD blade is replaced and continued to be used. After receiving the need to replace the blade, the tool technician generally observes whether the tool body is damaged and determines whether the blade can be replaced and trimmed. Then, the blade size is obtained by measuring the size of the tool groove, and then the margin is added on the basis of the measured blade size to draw the blade diagram. The blade measurement and drawing is crucial. If the blade measurement is larger than the actual value, it will make it difficult to put the blade into the original tool groove; if the blade measurement is smaller than the actual value, there will be a weld, which affects the appearance, and it is also easy to get chips during use, affecting the workpiece processing quality.

[0004] When measuring specifically, there are two types of slots for PCD inserts. The first type is that the slot bottom only includes the slot arc segment. In this case, a vernier caliper can be used to measure the length and width of the PCD insert, and a radius gauge can be used to measure the size of the positioning arc to finally obtain the size of the PCD insert. However, for another type of slot, the slot bottom includes two slot arc segments and a straight slot bottom segment between the two slot arc segments. A vernier caliper and a radius gauge are first used to measure the width of the insert and the size of the slot arc segment. However, for the measurement of the straight slot bottom segment between the two slot arc segments, a vernier caliper is generally used for rough measurement, and the size of the straight slot bottom segment between the two slot arc segments of the insert is inferred based on the measurement experience of the technicians. This is limited by the work experience of the designers, and the dimensional measurement is unstable and prone to errors. Alternatively, professional instruments and equipment such as optical measuring instruments and tool microscopes are used for measurement. This measurement method will occupy production equipment, use more production resources, and tool clamping and measurement will greatly waste the designer's time and work efficiency is extremely low. Utility Model Content

[0021] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0022] First, the technical solution of the utility model is generally described as follows:

[0023] PCD cutting tools are widely used in various fields due to their high hardness, high compressive strength, good thermal conductivity and wear resistance. Figure 1The PCD tool shown in the figure is designed and conceived. Since the end of the tool base 10 of this type of PCD tool has blades of different gears, when the PCD blade is replaced after the blade is damaged, the blade size needs to be re-measured to process and manufacture the PCD blade. The PCD blade is generally assembled in the tool groove 20. For some tool grooves that include two tool groove arc segments and a groove bottom straight segment between the two tool groove arc segments, since the boundary between the groove bottom straight segment between the two tool groove arc segments and the tool groove arc segments on both sides cannot be accurately viewed by the naked eye, the vernier caliper can only be used for rough measurement, and the size measurement is unstable and prone to errors. The use of professional instruments and equipment such as optical measuring instruments and tool microscopes for measurement is costly and has extremely low work efficiency.

[0024] The utility model is based on the problems of the prior art to conceive a PCD tool blade changing measurement tool, which is convenient to use and ensures accurate measurement results. The PCD tool blade changing measurement tool of the utility model comprises comparison calipers arranged in groups, each comparison caliper has a comparison contour line matching tool grooves of different specifications. Specifically, the comparison contour line of the comparison caliper has a comparison arc segment corresponding to the tool groove arc segments of different specifications, and the comparison contour line of the comparison caliper also has a comparison straight segment corresponding to the groove bottom straight segment of each different specification. By setting each comparison caliper to a different comparison size according to the tool groove size, it is used to match with blades of different sizes, and a suitable comparison caliper is selected to compare with the tool groove to realize the size acquisition of the blade of the PCD tool. When using, it is only necessary to select the comparison caliper for comparison, and the later drawing and processing are completed by comparing with the size of the suitable comparison caliper. It is easy to use and can be used repeatedly for many times, and the data is accurate, ensuring a good measurement effect.

[0025] Specific embodiment of the PCD tool change measuring tool of the utility model:

[0026] The structural schematic diagram of the PCD tool changer measuring tool of the utility model is as follows Figure 2-3 As shown, a PCD tool changing measuring tool includes comparison calipers arranged in groups. Since each comparison caliper is independently arranged, in order to facilitate use and not be easily confused during long-term use, the PCD tool changing measuring tool also includes a accommodating box 8 for placing each comparison caliper. Each comparison caliper has a comparison contour line for matching with tool grooves 20 of different specifications. In this embodiment, the PCD tool has two tool groove arc segments and a groove bottom straight section between the two tool groove arc segments. Therefore, the comparison contour line includes two comparison arc segments 2 for matching with the two tool groove arc segments of the blade. In this embodiment, taking the comparison arc segments 2 of the comparison calipers of each group having the same size as an example, the comparison contour line also includes a comparison straight section 1 between the two comparison arc segments 2. The comparison straight section 1 of each comparison caliper has a different comparison size for comparison and matching with the groove bottom straight section of the tool groove 20.

[0027] In order to facilitate comparison and use, the comparison caliper is a sheet structure. Since the comparison caliper is thicker, it is easy to produce errors in measurement due to its own thickness. Therefore, preferably, the thickness of the comparison caliper is between 0.3-0.6mm. In this embodiment, the thickness is specifically selected to be 0.4mm. Of course, in other embodiments, the thickness can also be selected to be 0.3mm or 0.6mm. When the blade is thinner, it is convenient for technicians to compare more accurately and ensure the reliability of the comparison results. Or in other embodiments, the thickness of the comparison caliper can be slightly less than 0.3mm or slightly greater than 0.6mm.

[0028] The structure of the comparison caliper other than the comparison contour line can be used without surface treatment, but because it has sharp edges, it is easy to scratch the operator's hands when in use. Therefore, in order to facilitate operation and use and ensure a certain degree of safety, preferably, one side of the comparison caliper in the thickness direction is the observation surface facing the observer when in use, and the edge of the observation surface is set as a rounded structure 6, and the other side is the fitting surface for fitting with the knife groove, and the edge of the fitting surface is set as a chamfered structure 7. Since one side of the comparison caliper still needs to be measured and compared, only the edge of the comparison caliper in the thickness direction facing the observer is set as a rounded structure 6. The rounded structure 6 can remove sharp edges and prevent cutting the user, and then the edge of the other side used for comparison is set as a chamfered structure 7, which will not affect the comparison effect, and can reduce wear, remove burrs and other effects. Of course, in other embodiments, all edges can be set as chamfered structures 7, or all edges except the comparison contour line can be set as rounded structures 6.

[0029] The comparison straight section 1 of the comparison caliper can be set to a straight structure, but when the human eye observes the comparison result, it is not easy to observe because the comparison straight section 1 is thick. Therefore, in order to facilitate the naked eye to check the comparison result, preferably, the comparison straight section 1 is set to a draft angle. In this way, when the comparison is performed, the comparison straight section 1 is set to an inclined setting, which is convenient for checking the comparison result and will not cause errors.

[0030] In order to facilitate the selection of the comparison caliper, in this embodiment, preferably, the comparison caliper includes a handheld end 5 and a comparison end, and a comparison scale 3 for comparing the arc segment 2 and the straight segment 1 is provided on one side of the comparison end. In this way, when in use, the comparison scale 3 for comparing the arc segment 2 and the straight segment 1 is provided on one side of the comparison end, which is convenient for selecting the comparison caliper. The comparison scale 3 of the comparison caliper is located at the comparison end, and the comparison scale 3 can be directly viewed and recorded while measuring, which is intuitive and convenient. Of course, in other embodiments, the comparison scale 3 can also be set on the handheld end 5 of the comparison caliper.

[0031] Since the blade also needs to be measured in height, a vernier caliper can be used to measure it separately, but in order to further facilitate the measurement of the blade height, preferably, a height scale 4 is provided along the height direction of the comparison caliper. In this way, the blade height can be measured while measuring the size of the straight section of the blade, which is convenient to use and does not require additional separate measurement.

[0032] The scale drawn by conventional inkjet is easily worn out and unclear during long-term use. Therefore, in order to improve the durability of the comparison caliper, in this embodiment, the comparison scale 3 and the height scale 4 are both laser scales. The laser scale has good wear resistance, is clear and easy to view, and is more reliable during long-term use. The laser-printed scale is more accurate, so that the measurement result is more accurate.

[0033] In this embodiment, the storage box 8 is a square box body, and the edges and corners of the box body are rounded. In order to facilitate the placement of the comparison caliper, a plurality of storage slots 9 are provided on the storage box 8. The comparison calipers in groups are inserted into the respective storage slots 9 of the storage box 8. The depth of the storage slots 9 is less than the height of the comparison caliper. In this way, each comparison caliper has a protruding part in the storage box 8, which is convenient for users to access. The comparison calipers of various sizes are collected in the storage box 8 for easy use and storage to avoid loss.

[0034] Furthermore, in order to intuitively and conveniently take out the required comparison caliper, preferably, the comparison end of the comparison caliper is protruding from the receiving groove 9, so that the comparison scale 3 can be intuitively seen during use, which is convenient for personnel to choose a suitable comparison caliper, and ensure that one end of the comparison straight section 1 will not be worn during storage.

[0035] In order to facilitate the placement of the comparison caliper in the storage box 8 to make it more stable and to facilitate the manufacture of the storage box 8, preferably, the storage slot 9 is set as a rectangular slot, and the handheld end 5 of the comparison caliper is set as a handheld straight structure, and the handheld straight structure matches the size of the bottom of the rectangular slot. In this way, the storage slot 9 is a rectangular slot for easy manufacture, and matches the size of the handheld straight structure of the comparison caliper, which can ensure that the comparison caliper is more compact after placement. Of course, in other embodiments, the storage slot 9 of the storage box 8 can also be set as an arc slot, and the corresponding handheld end 5 of the comparison caliper can be set as an arc structure.

[0036] In this embodiment, since the PCD insert is made of black material, setting the comparison caliper to a bright material or setting the surface coating to a light color can make comparison easier, ensuring that the comparison contour line of the comparison caliper coincides more clearly with the contour of the PCD insert, making it easier to view.

[0037] Through the above description of the specific embodiment of the PCD tool changing measuring tool of the utility model, it can be seen that the PCD tool changing measuring tool of the utility model is provided with a group of comparison calipers. Since each comparison caliper has a comparison contour line for matching with tool grooves of different specifications, the comparison arc segment of the comparison contour line is used to match with the tool groove arc segment, and the comparison straight segment of the comparison contour line is used to match with the straight segment of the groove bottom. Each comparison caliper has a different comparison size for matching with blades of different sizes. A suitable comparison caliper is selected to compare with the tool groove to realize the size acquisition of the blade of the PCD tool. When using it, it is only necessary to select the comparison caliper for comparison, and the later drawing and processing are completed by comparing with the size of the suitable comparison caliper. It is easy to use and can be used repeatedly. The data is accurate, and a good measurement effect is guaranteed.
