Description

Clamp for circular inserts and insert machining equipment

Technical Field

The specification relates to the field of tooling design, and in particular relates to a clamp for a circular insert and insert processing equipment.

Background

Inserts in the field of molds refer to irregular mold fittings for embedding in the mold, which function to fix the mold plate and fill the space between the mold plate. In actual production, the end of the part-round insert needs to be subjected to secondary processing in order to meet the actual requirements.

Because the insert has a large amount in actual production, when the insert needs to be subjected to secondary processing, the insert can be clamped and processed only by one piece (such as by a three-jaw chuck and the like), which is time-consuming and labor-consuming, and therefore, a clamp for the circular insert needs to be designed to realize batch processing of the circular insert.

Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present specification, the drawings that are required to be used in the description of the embodiments will be briefly described below. It is apparent that the drawings in the following description are only some examples or embodiments of the present specification, and it is possible for those of ordinary skill in the art to apply the present specification to other similar situations according to the drawings without inventive effort. Unless otherwise apparent from the context of the language or otherwise specified, like reference numerals in the figures refer to like structures or operations.

As used in this specification and the claims, the terms "a," "an," "the," and/or "the" are not specific to a singular, but may include a plurality, unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that the steps and elements are explicitly identified, and they do not constitute an exclusive list, as other steps or elements may be included in a method or apparatus.

FIG. 1 is a schematic view of a circular insert according to some embodiments of the present description. As shown in fig. 1, the circular insert generally has a cylindrical-like shape. As two typical examples, the diameter of the circular insert (a) is 8mm in the drawing, and the diameter of the circular insert (b) is 11.26mm. For more description of circular inserts, see below.

Fig. 2 is a schematic structural view of a clip 100 of a circular insert according to some embodiments of the present description. Referring to fig. 2, in some embodiments, the clip 100 of the circular insert includes a clip body 110, a positioning portion 120, and a sliding block 130.

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

In some embodiments, the positioning portion 120 and the clamp body 110 may be detachably connected by a structure such as a bolt or a pin, and in some embodiments, the positioning portion 120 and the clamp body 110 may be fixedly connected by a method such as welding.

Referring to fig. 3, in some embodiments, the sliding block 130 is disposed on a side of the positioning portion 120 where the V-shaped groove 122 is formed, and is slidably disposed along a second direction, where the second direction is perpendicular to the first direction. In some embodiments, the sliding block 130 is configured to form a clamping space with the V-groove 122 for fixing a circular insert, which is disposed in the clamping space in such a manner that an axis thereof is parallel to the first direction, when the sliding block 130 approaches the positioning portion 120. When the circular insert meets the fixing requirement in the clamping space, one end of the circular insert extending out of the clamp can be machined.

In some embodiments, the requirement for fixing the circular insert in the clamping space may relate to the structure and machining precision of the circular insert, and assuming that 6 degrees of freedom are included in the X, Y, Z axes and corresponding rotation axes, a part of the circular insert fixing requirement is to limit 5 degrees of freedom, and a part of the circular insert fixing requirement is to limit 6 degrees of freedom, where a positioning plane is further required to be added to the circular insert fixing requirement to avoid the circular insert rotating on the axes (such as the central axes), which will be described in detail later.

In some embodiments, the plurality of V-shaped grooves 122 on the positioning portion 120 may be arranged along a third direction, the third direction is perpendicular to the first direction and the second direction, and the plurality of V-shaped grooves 122 arranged along the third direction may improve convenience when clamping the plurality of circular inserts.

In some embodiments, the clamp body 110 includes a securing structure 140 in a first direction, the securing structure 140 being coupled to the slider 130 by a first adjustment bolt 132, the first adjustment bolt 132 being configured to control movement of the slider 130 in a second direction. In some embodiments, the operator may gradually approach the sliding block 130 to the positioning portion 120 by rotating the first adjusting bolt 132, and fix the circular insert in the clamping space. In some embodiments, because the V-groove 122 has a degree of self-centering functionality, the operator can achieve clamping by turning the first adjustment bolt 132 to meet the above-described securing requirements of the circular insert.

In some embodiments, the sliding portion may further approach or separate from the positioning portion 120 by other mechanisms, such as a screw nut, a sleeve slide rail, or an adjusting bolt having one end fixed to the positioning portion 120, which is not limited in this specification.

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

In some embodiments, as shown in the circular insert of fig. 1, the end of the circular insert, which is far from the end to be machined, has a bottom structure similar to a cylinder (or a circular truncated cone), so in order to fix the circular insert, the positioning portion 120 and the sliding block 130 are provided with a limit groove 150 along a third direction, and 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. When the positioning portion 120 and the sliding block 130 are brought close together, the limit groove 150 forms a T-groove-like area to accommodate the bottom structure of the circular insert. In some embodiments, the limit slot 150 may be in the form of a square slot or a dovetail slot, or the like.

In some embodiments, to increase the adaptability of the fixture to circular inserts of different sizes, a plurality of limiting grooves 150 may be formed on the positioning portion 120 and the sliding block 130, and the plurality of limiting grooves 150 may be arranged along the first direction. When the positioning part 120 and the sliding block 130 are close, a plurality of sets of T-shaped grooves of different heights are formed in the first direction, and an operator can fix the bottom structure of the circular insert to the appropriate T-shaped groove according to the actual length of the circular insert, and contact the table top of the bottom structure with the side surface of the T-shaped groove in the first direction, so that when the clamp clamps a plurality of circular inserts of the same size, the clamping heights of the plurality of circular inserts are uniform.

When, as shown in the circular insert (b) of fig. 1, there is a special-shaped structure at the end to be machined of some circular inserts, the bottom structure of the circular insert generally needs additional planar positioning, that is, the bottom structure is contacted with a positioning plane on the bottom structure by a fixture, so as to ensure machining precision.

In some embodiments, the clamp body 110 includes an adjustment mechanism 160, the adjustment mechanism 160 is coupled to a side of the slider 130 proximate to the clamp body 110, and the adjustment mechanism 160 is configured to control movement of the slider 130 in a first direction. In some embodiments, the slider 130 is raised in the first direction by the adjustment mechanism 160, such that the limit slot 150 on the positioning portion 120 is offset from the limit slot 150 on the slider 130, resulting in the configuration shown in fig. 4. When the bottom structure of the circular insert is placed in the limit groove 150 on the positioning portion 120, the boss 152 between the limit grooves 150 on the sliding block 130 is partially contacted with the positioning plane on the bottom structure of the circular insert, so as to realize plane positioning.

By adding the adjusting 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 scene requiring planar positioning and not requiring planar positioning.

As shown in fig. 5, in some embodiments, the adjustment mechanism 160 may include a second adjustment bolt 161 and a top block 162 disposed sequentially in the first direction, the top block 162 abutting the slider 130, the second adjustment bolt 161 being configured to control movement of the slider 130 in the first direction. The operator can conveniently control the distance of the jacking block 162 moving in the first direction by rotating the second adjusting bolt 161, and jack up the sliding block 130, and according to the number of turns of the second adjusting bolt 161, the jacking height of the sliding block 130 can also be controlled. As shown in fig. 3, the operator can control the jack block 162 to jack up the slide block 130 by 4mm, realizing the planar positioning of the circular insert.

In some embodiments, the adjusting mechanism 160 may further include a return spring 163, where the return spring 163 is in driving connection with the second adjusting bolt 161, so as to control the second adjusting bolt 161 and the top block 162 to return to the initial position when the sliding block 130 does not need to be lifted, i.e. the limit slot 150 on the positioning portion 120 has the same height as the limit slot 150 on the sliding block 130 in the first direction, so that the processing of the circular insert without planar positioning is facilitated.

In some embodiments, the adjusting mechanism 160 may also be other mechanisms that can control the sliding block 130 to move in the first direction, such as a cylinder, a screw nut, a rack and pinion, etc., which is not limited in this specification.

Since the circular insert has a cylindrical outer contour, when the circular insert is positioned in the clamping space, both surfaces of the sliding block 130 and the V-groove 122 are respectively in line contact, and thus, for any size of the V-groove 122, the clamping space formed with the sliding block 130 can clamp the circular insert having a diameter within a certain range.

By way of example, while the V-groove 122 is designed to form a clamping space with the slider 130 for securing a circular insert having a diameter of 10mm, the V-groove 122 can also secure a circular insert having a diameter of 9mm or a circular insert having a diameter of 11mm, and meet securing requirements.

In some embodiments, the plurality of V-grooves 122 have at least two different sizes to form clamping spaces for securing circular inserts of different sizes.

In some embodiments, the size of the V-groove 122 may be expressed by a maximum distance across the V-groove 122 or a depth of the V-groove 122. In some embodiments, the size of the V-groove 122 is related to the diameter of the circular insert that is actually used for fixation, and thus the size of the V-groove 122 may be noted by the diameter of the circular insert that is fixed. For example, in the previous example, the dimensions of the V-groove 122 for securing a 10mm diameter circular insert may be noted as φ 10.

Compatibility with circular inserts of different diameters is achieved by at least two different sized V-grooves 122. Meanwhile, as described above, the plurality of limiting grooves 150 can realize compatibility with circular inserts of different lengths, and by combining the two structures, the clamping fixture can be suitable for fixing and clamping most of circular inserts without replacing the fixture, so that subsequent processing is facilitated.

In some embodiments, V-grooves 122 of different sizes are staggered. Because the clamp can only clamp one or more circular inserts with the same diameter in one operation, after the circular inserts are fixed in the clamping space, the interval between adjacent circular inserts is longer and more uniform due to the staggered V-shaped grooves 122, and the condition of uneven stress of the circular inserts during clamping is avoided.

As shown in fig. 6, in some embodiments, V-groove 122 includes a first V-groove 123, a second V-groove 124, and a third V-groove 125 from large to small, depending on the actual circular insert production needs.

In some embodiments, the first V-shaped groove 123 is configured to form a clamping space with the sliding block 130 for fixing a circular insert with a diameter of 6.5-16 mm, and the size of the first V-shaped groove 123 may be phi 6.5-16 by the labeling method described above.

The second V-shaped groove 124 is configured to form a clamping space with the sliding block 130 for fixing a circular insert with a diameter of 3.5-6.5 mm, and the size of the second V-shaped groove 124 may be phi 3.5-6.5 by the labeling method described above.

The third V-groove 125 is configured to form a clamping space for fixing a circular insert having a diameter of 2 to 4mm with the slider 130. The third V-shaped groove 125 may have a size of 2-4 mm by the labeling method described above.

In some embodiments, the first V-groove 123, the second V-groove 124, and the third V-groove 125 may be sequentially disposed in a circle. In some embodiments, the center distance between adjacent first V-grooves 123 is not less than 20mm, for example, the center distance between adjacent first V-grooves 123 may be 26mm.

Through setting up first V type groove 123, second V type groove 124 and third V type groove 125 for anchor clamps can centre gripping diameter is 2~16mm within range's circular mold insert, adaptation most production needs. In addition, the clamp can clamp 6 circular inserts with the same diameter and process the circular inserts at one time.

The clamp 100 for circular inserts shown in some embodiments of the present disclosure may be suitable for circular inserts with different lengths, diameters and positioning requirements, and has strong processing adaptability, and in addition, the clamp 100 may be used for clamping circular inserts in batches, so as to facilitate batch production of circular inserts. The fixture 100 further comprises an additional limiting mechanism, can realize the bottom plane positioning of the circular insert, and is compatible with various insert processing requirements.

In connection with fig. 7, a description will be given below taking, as an example, a process of fixing and clamping the circular insert (a) and the circular insert (b) as shown in fig. 1.

The diameters of the circular insert (a) and the circular insert (b) are all 6.5-16 mm, so that the first V-shaped groove 123 can be selected to realize fixed clamping. Taking the circular insert (a) as an example, first, an operator may place one or more (up to 6) circular inserts (a) in the first V-grooves 123, respectively, and select an appropriate limit groove 150 according to the length of the circular insert (a) such that the circular insert (a) bottom structure is placed in the limit groove 150. Then, the operator can gradually approach the sliding block 130 to the positioning portion 120 by rotating the first adjusting bolt 132 until the fixing clamping of the circular insert (a) is completed, as shown in fig. 7.

The clamping process of the circular insert (b) is similar to that of the circular insert (a), except that the operator also needs to raise the sliding block 130 by 4mm by rotating the second adjusting bolt 161, and control the positioning plane of the circular insert (b) to face the sliding block 130, and then rotate the first adjusting bolt 132 to gradually approach the sliding block 130 to the positioning part 120 until the fixing and clamping of the circular insert (b) are completed, and at this time, the positioning plane of the circular insert (b) is partially attached to the boss 152 between the limiting groove 150 on the sliding block 130, so that additional plane positioning is realized.

Some embodiments of the present disclosure also provide an insert machining apparatus including the above-described clamp 100 for a circular insert to achieve fixed clamping of the circular insert. In some embodiments, the insert machining apparatus may further include structure such as a tool to machine the circular insert.
