Description

Technical Field

[0001] This utility model relates to the field of cutting tool processing technology, and in particular to an assembled universal feed tray for a peripheral grinding machine for indexable cutting tools. Background Technology

[0002] Indexable insert peripheral grinders process a wide variety of cutting tools. The insert blanks need to be placed in a feed tray and then transported to the machining position by a robotic arm. Existing feed trays mainly fall into two categories: one where the inserts are horizontally positioned. The robotic arm first uses a magnetic or vacuum suction head to remove the insert blank, then places it on a posture conversion device to adjust it to a vertical position before the robotic arm clamps it and delivers it to the machining position for grinding. The other type is a vertically mounted feed tray. After clamping the insert blank, the robotic arm can directly deliver it to the machining position for grinding. A common characteristic of both types of feed trays is that a single tray size is used for inserts of a specific shape with an inscribed circle diameter within a certain range. Therefore, different insert shapes require different feed trays, and inserts of the same shape require multiple sizes to match. According to the national standard GB / T2076 "Rules for Designation of Indexable Inserts for Cutting Tools", there are 17 shapes of indexable inserts and 10 specifications of their inscribed circle diameter. Each shape of insert requires at least three specifications of material trays, which increases the production and supporting costs and the storage space of the supporting material trays.

[0003] Patent No. CN202120297283 discloses an inlaid CBN blade material tray. The depth of the blade placement groove can be adjusted by adjusting the unit tray, thereby accommodating blades of different lengths. However, the size of the through hole cannot be adjusted, so it cannot accommodate blades of different shapes and specifications.

[0004] Therefore, it is necessary to design a material tray that can accommodate more specifications and models of blades and allows for selection of placement methods as needed. Utility Model Content

[0005] To address the technical problems of fixed placement and limited applicable blade sizes in existing material trays, this invention provides an assembled universal material tray for indexable blade peripheral grinding machines.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an assembled universal tray for a peripheral grinding machine for indexable inserts, comprising a base plate, a pad, a support plate and a thickness positioning plate arranged in sequence. The base plate limits the insert along a first direction in a first plane, the support plate limits the insert along a second direction in a second plane, and the thickness positioning plate limits the insert along the thickness direction of the insert in a third plane. The pad is adapted to adjust the distance between the base plate and the support plate. The first plane, the second plane and the third plane are parallel to each other, the first direction is parallel to the second direction and perpendicular to the thickness direction of the insert.

[0007] In an optional embodiment of this utility model, the substrate and the support plate respectively have a first through groove and a second through groove that extend in the same direction and correspond one-to-one, and the width of the second through groove is greater than the width of the first through groove; the thickness positioning plate has a third through groove that is perpendicular to the extending direction of the first through groove.

[0008] In an optional embodiment of this utility model, the outer periphery of the substrate, pad, support plate and thickness positioning plate are provided with a plurality of mounting holes, and the fixing member passes through the mounting holes to fix the substrate, pad, support plate and thickness positioning plate.

[0009] In an optional embodiment of this utility model, at least three of the substrate, pad, support plate and thickness positioning plate are provided with positioning holes, and the remaining plate is provided with corresponding positioning posts.

[0010] In an optional embodiment of this utility model, the pad is a strip plate.

[0011] In an optional embodiment of this utility model, the second through groove passes through the support plate in the vertical direction, and the third through groove passes through the thickness positioning plate in the vertical direction.

[0012] In an optional embodiment of this utility model, the first through groove extends through the substrate in the vertical direction.

[0013] In an optional embodiment of this utility model, the top of the first through groove extends through the substrate, while the bottom does not extend through the substrate.

[0014] In an optional embodiment of this invention, the pad is arranged at the edge of the base plate and the support plate.

[0015] The beneficial effects of this utility model are:

[0016] This invention uses a base plate to support and limit the bottom of the blade, a support plate to support and limit the middle of the blade, and a thickness positioning plate to support and limit the upper part of the blade. The base plate, support plate, and thickness positioning plate can achieve two vertical directions of limitation in the horizontal plane, thereby achieving stable support and placement of the blade. In addition, by adjusting the height difference between the base plate and the support plate with a pad, different blades can be placed under the same limitation adjustment without changing the material tray, thus saving production costs and avoiding workshop clutter.

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] like Figures 1-3As shown, an assembled universal tray for a peripheral grinding machine for indexable inserts includes a base plate 1, a pad 4, a support plate 2, and a thickness positioning plate 3 arranged in sequence. The base plate 1 limits the insert 8 along a first direction in a first plane, the support plate 2 limits the insert 8 along a second direction in a second plane, and the thickness positioning plate 3 limits the insert 8 along the thickness direction of the insert 8 in a third plane. The pad 4 is adapted to adjust the distance between the base plate 1 and the support plate 2. The first plane, the second plane, and the third plane are parallel to each other, the first direction is parallel to the second direction, and perpendicular to the thickness direction of the insert 8.

[0027] For ease of description, this utility model places the substrate 1, pad 4, support plate 2 and thickness positioning plate 3 horizontally, and stacks the four plates vertically. The horizontal surface is divided into two vertical directions: front-back and left-right. The first and second directions are both left-right, and the third direction is the front-back.

[0028] The shape of blade 8 is as follows Figure 2 As shown, it is usually rhomboid. For blades 8 of different sizes, their length, width, and thickness are not equal, and the included angle between adjacent sides is also not equal.

[0029] The substrate 1 and the support plate 2 are at different heights, thus limiting the blade 8 in different planes. The bottom of the blade 8 is a pointed tip, placed on the substrate 1 and limited in the left and right directions, that is, at both ends of the rhomboid surface. The support plate 2 is located in the middle of the blade 8 and is also limited in the left and right directions. The thickness positioning plate 3 limits the thickness of the blade 8, thus making the blade 8 stand upright. The pad 4 can adjust the distance between the substrate 1 and the support plate 2. For blades 8 with different rhomboid sizes, only the number of pads 4 needs to be adjusted, and the substrate 1 and the support plate 2 do not need to be replaced. That is, the limiting space of the two in the left and right directions remains unchanged. By adjusting the height difference between the two, the support plate 2 is positioned at the corresponding width of the blade 8. For blades 8 with different thicknesses, only the thickness positioning plate 3 needs to be replaced.

[0030] Compared with the prior art, the substrate 1, pad 4, tray 2 and thickness positioning plate 3 in this utility model can be disassembled and assembled. The substrate 1, pad 4 and tray 2 are basically interchangeable, and the workshop does not need to stack different types of material trays. When processing different batches of tools, it is only necessary to select the appropriate number of pads 4 and the size of thickness positioning plate 3 according to the tool model for assembly. The assembly is convenient and quick, and the use cost is low.

[0031] The structure of the pallet is described below with reference to specific embodiments:

[0032] Example 1

[0033] like Figures 2-6As shown, an assembled universal tray for a peripheral grinding machine for indexable inserts includes a base plate 1, a pad plate 4, a support plate 2, and a thickness positioning plate 3 arranged in sequence. One or more pad plates 4 are provided as needed. The base plate 1 and the support plate 2 each have a first through groove 11 and a second through groove 21 extending in the same direction and corresponding to each other, with the width of the second through groove 21 being greater than the width of the first through groove 11. The thickness positioning plate 3 has a third through groove 31 perpendicular to the extending direction of the first through groove 11. The first through groove 11, the second through groove 21, and the third through groove 31 are all elongated grooves. The width direction of the first through groove 11 and the second through groove 21 limits the left and right directions of the insert 8, and the width direction of the third through groove 31 limits the thickness direction of the insert 8.

[0034] Because the width of the middle part of the diamond-shaped blade 8 is larger, the width of the second through groove 21 located at the top is greater than the width of the first through groove 11 located at the bottom.

[0035] In other alternative embodiments, several limiting holes can be provided on the substrate 1, the support plate 2 and the thickness positioning plate 3. However, the through slot design is more flexible. Taking the first through slot 11 as an example, it is not limited in the thickness direction of the blade 8. The thickness direction is only limited by the third through slot 31, thereby avoiding the need to replace the substrate 1 after the blade 8 model changes.

[0036] For the installation of the four types of plates, the outer periphery of the base plate 1, pad plate 4, support plate 2 and thickness positioning plate 3 are provided with several mounting holes 5. The fasteners pass through the mounting holes 5 to fix the base plate 1, pad plate 4, support plate 2 and thickness positioning plate 3.

[0037] The second through slot 21 and the third through slot 31 need to allow the blade 8 to pass through. Therefore, the second through slot 21 passes through the support plate 2 in the vertical direction, and the third through slot 31 passes through the thickness positioning plate 3 in the vertical direction.

[0038] The first through groove 11 is located at the bottom of the blade 8. It can penetrate the substrate 1 in the vertical direction, or it can only penetrate the substrate 1 at the top and not at the bottom.

[0039] The pad 4 can be a large panel with a size similar to that of the substrate 1, the support plate 2 and the thickness positioning plate 3, but it needs to have a groove inside to expose the first through groove 11 and the second through groove 21 to avoid affecting the placement of the blade 8.

[0040] Example 2

[0041] The difference between this embodiment and Embodiment 1 is that the pad 4 is a strip plate, that is, the width of the pad 4 is narrower. It can be located between adjacent second through slots 21, or it can be arranged along the four edges of the base plate 1 and the support plate 2.

[0042] Example 3

[0043] Based on the above embodiments, at least three of the plates—substrate 1, pad 4, support plate 2, and thickness positioning plate 3—are provided with positioning holes 6, and the remaining plate is provided with corresponding positioning posts 7. For example, if the substrate 1 is provided with positioning posts 7, then the pad 4, support plate 2, and thickness positioning plate 3 are provided with corresponding positioning holes 6, which facilitates quick alignment and installation of the mounting holes 5 on the four types of plates. In other optional embodiments, the positioning posts 7 can also be provided on the support plate 2 (e.g., ...). Figure 4 (as shown) or on the thickness positioning plate 3.

[0044] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In this specification, the illustrative expressions of the terms do not necessarily refer to the same embodiments. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments.

[0046] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
