Detailed implementation manners

[0023] To more clearly illustrate the technical solutions of the embodiments of this specification, the accompanying drawings required for the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some examples or embodiments of this specification. For those of ordinary skill in the art, without creative efforts, this specification can also be applied to other similar scenarios based on these drawings. Unless obvious from the language context or otherwise stated, the same reference numerals in the figures represent the same structure or operation.

[0024] As shown in this specification and the claims, unless the context clearly indicates an exceptional situation, words such as "a", "an", "one", and / or "the" are not specifically singular and may also include plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of the clearly identified steps and elements, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0025] Figure 1 It is a schematic diagram of the circular insert as shown in some embodiments of this specification. As Figure 1 shown, the circular insert usually has a shape similar to a cylinder. As two typical examples, the diameter of the circular insert (a) in the figure is 8 mm, and the diameter of the circular insert (b) is 11.26 mm. More descriptions about the circular insert can be found in the relevant content later.

[0026] Figure 2 It is a schematic structural diagram of the fixture 100 for the circular insert as shown in some embodiments of this specification. Refer to Figure 2 , in some embodiments, the fixture 100 for the circular insert includes a fixture body 110, a positioning part 120, and a sliding block 130.

[0027] In some embodiments, the positioning part 120 is connected to the fixture body 110, and a plurality of V-shaped grooves 122 are formed along a first direction on one side of the positioning part 120. By providing a plurality of V-shaped grooves 122 on the positioning part 120, it is possible to clamp a plurality of circular inserts at one time for simultaneous machining.

[0028] In some embodiments, the positioning part 120 and the fixture body 110 can be detachably connected by structures such as bolts or pins. In some embodiments, the positioning part 120 and the fixture body 110 can be fixedly connected by means such as welding.

[0029] Meanwhile, referring to Figure 3 , in some embodiments, the sliding block 130 is disposed on the side of the positioning part 120 where the V-shaped grooves 122 are formed and is slidably arranged along a second direction, wherein the second direction is perpendicular to the first direction. In some embodiments, the sliding block 130 is configured such that when the sliding block 130 approaches the positioning part 120, a clamping space for fixing the circular insert is formed with the V-shaped grooves 122, and the circular insert is disposed in the clamping space with its axis parallel to the first direction. After the circular insert meets the fixing requirements in the clamping space, the end of the circular insert extending out of the fixture can be machined.

[0030] In some embodiments, the fixing requirements of the circular insert in the clamping space may be related to the structure of the circular insert and the machining accuracy. Assuming that there are a total of 6 degrees of freedom on the X, Y, Z axes and the corresponding rotation axes, without considering repeated positioning, the fixing requirements for some circular inserts are to restrict 5 degrees of freedom, and the fixing requirements for some circular inserts are to restrict 6 degrees of freedom. At this time, a positioning plane needs to be added to the circular insert fixing type to prevent the circular insert from rotating on the axis (such as the central axis). For specific details, reference can be made to the relevant descriptions later.

[0031] In some embodiments, the plurality of V-shaped grooves 122 on the positioning part 120 can be arranged along a third direction, and the third direction is perpendicular to the first direction and the second direction respectively. The plurality of V-shaped grooves 122 arranged along the third direction can improve the convenience of clamping a plurality of circular inserts.

[0032] In some embodiments, the fixture body 110 includes a fixing structure 140 in the first direction, and the fixing structure 140 is connected to the sliding block 130 by a first adjusting bolt 132. The first adjusting bolt 132 is configured to control the movement of the sliding block 130 along the second direction. In some embodiments, the operator can rotate the first adjusting bolt 132 to gradually move the sliding block 130 closer to the positioning part 120 and fix the circular insert in the clamping space. In some embodiments, due to the self-centering function of the V-shaped grooves 122 to a certain extent, the operator can rotate the first adjusting bolt 132 to achieve clamping to meet the above-mentioned fixing requirements of the circular insert.

[0033] In some embodiments, the sliding part can also approach or move away from the positioning part 120 through other mechanisms, such as a lead screw nut, a sleeve slide rail, or an adjusting bolt with one end fixed to the positioning part 120, etc. This specification does not make any restrictions.

[0034] With the fixing structure 140 and the first adjusting bolt 132, the operator can directly control the displacement of the sliding part by rotation.

[0035] In some embodiments, such as Figure 1 As shown in the circular insert, the bottom structure of the circular insert away from the end to be machined has a bottom structure similar to a cylinder (or frustum of a cone). Therefore, in order to fix the circular insert, the positioning part 120 and the sliding block 130 are provided with limiting grooves 150 along the third direction. In the first direction, the limiting grooves 150 on the positioning part 120 and the limiting grooves 150 on the sliding block 130 have the same height. When the positioning part 120 and the sliding block 130 approach each other, the limiting grooves 150 form a region similar to a T-shaped groove to accommodate the bottom structure of the circular insert. In some embodiments, the limiting grooves 150 can be in the form of square grooves or dovetail grooves, etc.

[0036] In some embodiments, in order to increase the adaptability of the fixture to circular inserts of different sizes, a plurality of limiting grooves 150 can be provided on the positioning part 120 and the sliding block 130, and the plurality of limiting grooves 150 are arranged along the first direction. When the positioning part 120 and the sliding block 130 approach each other, multiple groups of T-shaped grooves with different heights are formed in the first direction. The operator can fix the bottom structure of the circular insert in a suitable T-shaped groove according to the actual length of the circular insert, and make the table surface of the bottom structure contact the side surface of the T-shaped groove in the first direction, so that when the fixture clamps a plurality of circular inserts of the same size, the clamping heights of the plurality of circular inserts are consistent.

[0037] Such as Figure 1 As shown in the circular insert (b), when there is a special-shaped structure at one end of some circular inserts to be machined, usually the bottom structure of the circular insert requires additional planar positioning, that is, by contacting the positioning plane on the bottom structure with the fixture to ensure the machining accuracy.

[0038] In some embodiments, the fixture body 110 includes an adjusting mechanism 160; the adjusting mechanism 160 is connected to the side of the sliding block 130 close to the fixture body 110; the adjusting mechanism 160 is configured to control the sliding block 130 to move along the first direction. In some embodiments, by means of the adjusting mechanism 160, the sliding block 130 is raised in the first direction, and further the limiting grooves 150 on the positioning part 120 and the limiting grooves 150 on the sliding block 130 are offset, forming as shown in Figure 4When the bottom structure of the circular insert is placed in the limiting groove 150 on the positioning portion 120, the boss 152 between the limiting grooves 150 on the sliding block 130 contacts the positioning plane on the bottom structure of the circular insert to achieve plane positioning.

[0039] By adding the adjustment mechanism 160 , the clamp can lift or restore the position of the sliding block 130 according to actual needs, so as to adapt to the circular insert clamping scenarios requiring planar positioning and not requiring planar positioning.

[0040] like Figure 5 As shown, in some embodiments, the adjustment mechanism 160 may include a second adjustment bolt 161 and a top block 162 arranged in sequence along the first direction, the top block 162 abutting against the sliding block 130; the second adjustment bolt 161 is configured to control the movement of the sliding block 130 in the first direction. The operator can conveniently control the distance the top block 162 moves in the first direction by rotating the second adjustment bolt 161, thereby lifting the sliding block 130, and the height to which the sliding block 130 is lifted can also be controlled according to the number of turns of the second adjustment bolt 161. Figure 3 As shown, the operator can control the lifting block 162 to lift the sliding block 130 by 4 mm to achieve planar positioning of the circular insert.

[0041] In some embodiments, the adjustment mechanism 160 may further include a return spring 163, which is in transmission connection with the second adjustment bolt 161 to control the second adjustment bolt 161 and the top block 162 to return to the initial position when there is no need to lift the sliding block 130, that is, in the first direction, the limit groove 150 on the positioning portion 120 and the limit groove 150 on the sliding block 130 have the same height, which is convenient for the processing of circular inserts without plane positioning.

[0042] In some embodiments, the adjustment mechanism 160 may also be other mechanisms capable of controlling the movement of the sliding block 130 in the first direction, such as a cylinder, a screw nut, a gear rack, etc., which is not limited in this specification.

[0043] Since the circular insert has a cylindrical outer contour, when the circular insert is located in the clamping space, it is in line contact with the two surfaces of the sliding block 130 and the V-groove 122 respectively. Therefore, for any size of the V-groove 122, the clamping space formed by it and the sliding block 130 can clamp circular inserts with a diameter within a certain range.

[0044] For example, when the designed V-groove 122 and the sliding block 130 form a clamping space for fixing a circular insert with a diameter of 10 mm, the V-groove 122 can usually also fix a circular insert with a diameter of 9 mm or a circular insert with a diameter of 11 mm and meet the fixing requirements.

[0045] In some embodiments, the plurality of V-shaped grooves 122 have at least two different sizes to form a clamping space for fixing circular inserts of different sizes.

[0046] In some embodiments, the size of the V-shaped groove 122 can be represented by parameters such as the maximum distance between the two sides of the V-shaped groove 122 or the depth of the V-shaped groove 122. In some embodiments, the size of the V-shaped groove 122 is related to the diameter of the circular insert actually used for fixing. Therefore, the size of the V-shaped groove 122 can be marked by the diameter of the fixed circular insert. For example, in the foregoing example, the size of the V-shaped groove 122 for fixing a circular insert with a diameter of 10 mm can be marked as φ10.

[0047] By means of at least two different sizes of V-shaped grooves 122, compatibility with circular inserts of different diameters is achieved. At the same time, as described above, the plurality of limiting grooves 150 can achieve compatibility with circular inserts of different lengths. By combining the above two structures, it is possible to be applicable to the fixing and clamping of the vast majority of circular inserts without replacing the fixture, so as to facilitate subsequent processing.

[0048] In some embodiments, the V-shaped grooves 122 of different sizes are arranged in an interleaved manner. Since the fixture can only clamp one or more circular inserts with the same diameter in one operation, the interleaved arrangement of the V-shaped grooves 122 makes the clamping space longer and more uniform between adjacent circular inserts after fixing the circular inserts, avoiding the situation of uneven force on the circular inserts during clamping.

[0049] As Figure 6 shown, in some embodiments, according to the actual production requirements of circular inserts, the V-shaped groove 122 includes a first V-shaped groove 123, a second V-shaped groove 124, and a third V-shaped groove 125 from large to small.

[0050] In some embodiments, the first V-shaped groove 123 is configured to form a clamping space for fixing a circular insert with a diameter between 6.5 and 16 mm with the sliding block 130; adopting the marking method described above, the size of the first V-shaped groove 123 can be φ6.5 - 16.

[0051] The second V-shaped groove 124 is configured to form a clamping space for fixing a circular insert with a diameter between 3.5 and 6.5 mm with the sliding block 130; adopting the marking method described above, the size of the second V-shaped groove 124 can be φ3.5 - 6.5.

[0052] The third V-shaped groove 125 is configured to form a clamping space for fixing a circular insert with a diameter between 2 and 4 mm with the sliding block 130. Adopting the marking method described above, the size of the third V-shaped groove 125 can be φ2 - 4 mm.

[0053] In some embodiments, the first V-shaped groove 123, the second V-shaped groove 124, and the third V-shaped groove 125 can be arranged in a cyclic order. In some embodiments, the center distance between adjacent first V-shaped grooves 123 is not less than 20 mm. For example, the center distance between adjacent first V-shaped grooves 123 can be 26 mm.

[0054] By providing the first V-shaped groove 123, the second V-shaped groove 124, and the third V-shaped groove 125, the fixture can clamp circular inserts with a diameter in the range of 2 to 16 mm, meeting the production requirements of the vast majority. In addition, the fixture can clamp six circular inserts with the same diameter in one clamping and perform machining.

[0055] The fixture 100 for circular inserts shown in some embodiments of this specification can be applicable to circular inserts with different lengths, diameters, and positioning requirements, having strong machining adaptability. In addition, the fixture 100 can clamp circular inserts in batches, thus facilitating the batch production of circular inserts. The fixture 100 also includes an additional limiting mechanism, which can achieve the bottom plane positioning of circular inserts and is compatible with various insert machining requirements.

[0056] Combined Figure 7 , hereinafter, the fixed clamping process of the circular inserts (a) and circular inserts (b) as shown in Figure 1 will be taken as an example for illustration.

[0057] Since the diameters of the circular inserts (a) and circular inserts (b) are both in the range of 6.5 to 16 mm, the first V-shaped groove 123 can be selected to achieve fixed clamping. Taking the circular insert (a) as an example, first, the operator can place one or more (at most six) circular inserts (a) into the first V-shaped groove 123 respectively, and select a suitable limiting groove 150 according to the length of the circular insert (a) so that the bottom structure of the circular insert (a) is placed in the limiting groove 150. Then, the operator can gradually move the sliding block 130 closer to the positioning portion 120 by rotating the first adjusting bolt 132 until the fixed clamping of the circular insert (a) is completed, as shown in Figure 7 .

[0058] The clamping process of the circular insert (b) is similar to that of the circular insert (a). The difference is that: the operator also needs to raise the sliding block 130 by 4 mm by rotating the second adjusting bolt 161, control the positioning plane of the circular insert (b) to face the sliding block 130, and then gradually move the sliding block 130 closer to the positioning portion 120 by rotating the first adjusting bolt 132 until the fixed clamping of the circular insert (b) is completed. At this time, the positioning plane of the circular insert (b) is partially in contact with the boss 152 between the limiting groove 150 on the sliding block 130, realizing additional plane positioning.

[0059] Some embodiments of this specification also provide an insert processing device, including the fixture 100 for the above-mentioned circular insert to achieve the fixed clamping of the circular insert. In some embodiments, the insert processing device may further include structures such as cutting tools to process the circular insert.

[0060] This insert processing device has high clamping and processing efficiency and can quickly produce a large number of circular inserts that meet the requirements. The basic concepts have been described above. Obviously, for those skilled in the art, the above detailed disclosure is only an example and does not constitute a limitation to this specification. Although not explicitly stated here, those skilled in the art may make various modifications, improvements, and corrections to this specification.
