Description

Technical Field

[0001] The utility model relates to the field of automated production lines, and particularly to a machining positioning device. Background Art

[0002] With the development of society, automated production lines have gradually been applied in the manufacturing industry. At present, the vast majority of automatic lines on the market are used for producing batch parts because batch parts have universality and interchangeability, with extremely low frequencies of mold change and high process standardization.

[0003] However, most of the machined parts in some industries are single, scattered, and non-standard parts. Almost every part has different structures, shapes, and dimensions, and the workpieces have almost no universality and interchangeability. Due to the characteristics of single, scattered, and non-standard parts, placing single, scattered, and non-standard parts on an automatic production line for production and installation will cause the automatic line to frequently change molds inside or outside the line. At the same time, it also requires a large amount of time for installation, clamping correction, and machining debugging, and it is not easy to position single, scattered, and non-standard parts, which easily causes the automatic line to stop or standby, resulting in relatively low production efficiency for single, scattered, and non-standard parts. Summary of the Utility Model

[0004] Therefore, in order to overcome at least some defects and deficiencies of the above prior art, the embodiments of the present utility model propose a machining positioning device to improve the production efficiency of the automatic line for single, scattered, and non-standard parts.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] In this embodiment, the machining positioning device 1 can be applied to mass produce single-piece non-standard parts on an automatic production line. The single-piece non-standard parts are workpieces that do not have universality and interchangeability. Since the structures, shapes, and sizes of basically each single-piece non-standard part are different, and the production tooling on the automatic production line needs to mass produce, if single-piece non-standard parts are produced, it is necessary to frequently replace the molds and spend a large amount of time on clamping correction and machining debugging, which seriously affects the efficiency of producing single-piece non-standard parts on the automatic production line. To solve the difficulty of producing single-piece non-standard parts on the automatic production line, the present application proposes a new machining positioning device for such defects.

[0032]

The first embodiment

[0033] In this embodiment, as Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides a machining positioning device 1. The machining positioning device 1 includes, for example: a robot adapter 10, a pallet 20, and a positioning portion 30. The positioning portion 30 is a positioning pin and can be used to position the pallet 20 on a machining automatic production line.

[0034] Specifically, the robot adapter 10 is disposed on one side of the pallet 20 and connected to the pallet 20. The positioning portion 30 is disposed at the bottom end of the pallet 20 and fixedly connected to the pallet 20. Among them, the robot adapter 10 is used to adapt to various robots on the automatic line, such as a rail-type robot, etc., facilitating the robot to grasp and place the pallet, workpiece, etc. The positioning portion 30 is, for example, a clamping member, and the clamping member is, for example, a zero-point clamping pin. The positioning portion 30 can be used to clamp with a machine tool on the automatic line. A zero-point chuck corresponding to the zero-point clamping pin can be provided on the machine tool, so that the pallet can be accurately positioned on the machine tool and clamped with the machine tool. The pallet 20 is, for example, a universal pallet. The positioning portion 30 can be disposed at the bottom end of the pallet 20, and the robot adapter can be disposed on one side edge of the pallet 20.

[0035] A scale line 21 is provided on the surface of one end of the pallet 20 away from the positioning portion 30. A pin hole 22 and a threaded hole 23 are arranged on the scale line 21. The pin hole 22 and the threaded hole 23 are used to install a workpiece or a tooling, and the scale line 21 is used to determine the installation position of the workpiece or the tooling. The pin hole 22 is, for example, a positioning hole, and the threaded hole 23 is, for example, a screw hole. The pin hole 22 and the threaded hole 23 are arranged in an array on the scale line 21 of the pallet 20. As Figure 2 shown, a scale line 21 is provided on the pallet. The scale line 21 is, for example, a scale line of a coordinate system. The coordinate origin can be, for example, the lower left corner of the pallet 20. The scale line 21 includes, for example, a horizontal scale line and a vertical scale line. The horizontal scale line and the vertical scale line are perpendicular to each other and intersect. A positioning hole and a screw hole can be arranged at the intersection position. The screw hole is, for example, an M12 screw hole with a thread diameter of 12 mm and a screw hole with a thread diameter of 8 mm. The positioning hole is, for example, a Φ10 positioning hole with a diameter of 10 mm for positioning. As Figure 2As shown in the figure, on the first horizontal scale line above the tray from top to bottom, M12 screw holes and M8 screw holes are equidistantly spaced. Their arrangement is, for example, M12 screw hole, M8 screw hole, M12 screw hole, M8 screw hole, M12 screw hole...; The Φ10 positioning hole is arranged above the M8 screw hole. The diameter of the M8 screw hole is slightly smaller than that of the positioning hole, and there can be a certain gap during assembly to facilitate the assembly and disassembly of the tooling or workpiece set on the tray 20. When directly clamping a workpiece on the tray 20, the clamped workpiece is, for example, a large piece or a special-shaped piece. The workpiece can be clamped to the tray 20 through process holes, side jacks or pressing plates, etc., and the workpiece is positioned through the pin holes 22.

[0036] Specifically, before using the machining positioning device 1, a zero-point chuck needs to be installed on the workbench of each machine tool in the automatic line for quick interchange, positioning and clamping with the tray 20 on the machining positioning device 1. There are an off-machine tray storage rack and an off-machine tool holder in the automatic line; An off-machine loading station is set outside the automatic line for clamping single-piece, scattered and non-standard workpieces. A rail-type manipulator is adopted on the automatic line for grasping and placing trays and tools.

[0037] In this embodiment, by setting the scale line 21 on the tray 20 and arranging the pin holes 22 and threaded holes 23 on the scale line 21, the installation position of the workpiece or tooling is determined by the scale line 21, and then the workpiece or tooling is installed through the pin holes 22 and threaded holes 23. The workpiece can be directly positioned, or the workpiece can be positioned on the tooling after installing the tooling, which can facilitate the blanking of the workpiece to the automatic line for processing and production, so that the production efficiency of producing single-piece, scattered and non-standard parts can be improved. During blanking, the workpiece to be processed determines the structural shape of the positioned position of the workpiece to be processed according to the pin holes 22, threaded holes 23 or tooling of the machining positioning device 1, so that the workpiece to be processed can be installed on the tray 20 or the tooling.

[0038] In a preferred embodiment of this embodiment, as Figure 3 shown, the machining positioning device 1 further includes a clamping tooling 40. The clamping tooling 40 is arranged at one end of the tray 20 away from the positioning part 30, and the clamping tooling 40 is detachably connected to the pin holes 22 and the threaded holes 23 respectively. The clamping tooling 40 can be, for example, a dovetail tooling, a vise tooling or other clamps that can be used for processing. By setting the clamping tooling 40 to adapt to the shape and processing requirements of different single-piece, scattered and non-standard workpieces, the production efficiency of the automatic line for producing single-piece, scattered and non-standard parts can be improved.

[0039]

Second Embodiment

[0040] In this embodiment, the machining positioning device is basically the same as the machining positioning device in the first embodiment, and the difference lies in that: the clamping tooling 40 is a dovetail tooling 50.

[0041] Specifically, as Figure 4 and Figure 5 shown, the clamping tooling 40 is a dovetail tooling 50. The dovetail tooling 50 includes a first fixed seat 501 and a dovetail clamping head 502. The first fixed seat 501 is detachably connected to the pallet 20, and the dovetail clamping head 502 is disposed on a side of the first fixed seat 501 away from the pallet (20). Wherein, a clamping groove 503 is provided on the dovetail clamping head 502, and the clamping groove 503 is used for clamping the workpiece. Among them, the dovetail tooling 50 can be, for example, a dovetail tooling clamp in the prior art or a combined structure of a dovetail clamp + a dovetail groove. A dovetail clamp is a mechanical device for fixing a workpiece. It usually has a dovetail shape design and can cooperate with a dovetail groove on a machine tool or other fixtures. The advantage of this kind of clamp is that it can provide a strong clamping force and allows the workpiece to be positioned and clamped in multiple directions.

[0042] The dovetail tooling 50 is clamped and fixed on the pallet 20. The bottom end of the first fixed seat 501 is fixed on the pallet 20 through a pin hole 22 and a threaded hole 23. Scale lines can be provided on the dovetail tooling 50. When clamping the workpiece, positioning and clamping can be carried out according to the scale lines on the dovetail tooling 50, and multiple workpieces can be clamped at one time. Such dovetail tooling 50 can be used for the first clamping and tooling of the workpiece. When the workpiece incoming material is a square material and the blank parts with uneven shapes such as plasma cutting and water cutting, the process machining allowance of the workpiece is ≥ 2.5 mm on each side.

[0043] By providing the dovetail tooling 50, the workpiece can be fixed through the clamping groove 503 on the dovetail tooling 50 and the clamping position dimensions of the workpiece can be unified. At the same time, multiple workpieces can be clamped and processed through the dovetail tooling 50 at one time, thereby improving the production efficiency of subsequent single-piece non-standard parts on the automatic line.

[0044] Furthermore, the groove width of the clamping groove 503 is between 25 mm and 100 mm, such as 25, 50 or 100 mm. The actual groove width size of the clamping groove 503 can be determined according to the size of the workpiece, and specific limitations are not made here.

[0045] Even further, as Figure 5 shown, the dovetail tooling 50 includes a first dovetail tooling 51 and a second dovetail tooling 52. The first dovetail tooling 51 and the second dovetail tooling 52 are both disposed on the pallet 20. The first dovetail tooling 51 and the second dovetail tooling 52 are arranged at intervals and the first dovetail tooling 51 and the second dovetail tooling 52 are disposed on the same row of the scale lines 21. Wherein, as Figure 4As shown, the groove width D1 of the clamping grooves 503 of the first dovetail tooling 51 and the second dovetail tooling 52 is 100 millimeters. The specific structures of the first dovetail tooling 51 and the second dovetail tooling 52 can refer to the specific structure of the dovetail tooling 50 introduced above, which will not be elaborated here. As Figure 4 shown, the centers of the bottoms of the first dovetail tooling 51 and the second dovetail tooling 52 can be located on the same row of scale lines 21, so that the arrangement of the first dovetail tooling 51 and the second dovetail tooling 52 on the pallet 20 is more orderly, and it can also enable the first dovetail tooling 51 and the second dovetail tooling 52 to clamp multiple workpieces at the same time. Of course, in other embodiments, the centers of the bottoms of the first dovetail tooling 51 and the second dovetail tooling 52 can be located on the same column of scale lines 21, that is, the first dovetail tooling 51 and the second dovetail tooling 52 are arranged vertically. The specific installation positions of the first dovetail tooling 51 and the second dovetail tooling 52 can be adjusted according to the actual situation and are not limited here.

[0046] By setting large dovetail tooling, that is, the first dovetail tooling 51 and the second dovetail tooling 52 with a groove width of 100 millimeters for the clamping grooves, the dovetail clamping positions of the workpieces can be unified, which is convenient for subsequent production and improves the production efficiency of the workpieces (that is, single-piece, scattered, non-standard parts) on the automatic line.

[0047]

Third Embodiment

[0048] In this embodiment, the machining positioning device is basically the same as the machining positioning device in the second embodiment, and the difference lies in that: the dovetail tooling 50 includes a first dovetail tooling 51, a second dovetail tooling 52, a third dovetail tooling 53, and a fourth dovetail tooling 54.

[0049] Specifically, as Figure 6 and Figure 7As shown, the dovetail tooling 50 includes a first dovetail tooling 51, a second dovetail tooling 52, a third dovetail tooling 53, and a fourth dovetail tooling 54. The first dovetail tooling 51, the second dovetail tooling 52, the third dovetail tooling 53, and the fourth dovetail tooling 54 are all arranged on the tray 20. The first dovetail tooling 51 and the second dovetail tooling 52 are arranged at intervals and are located on the same row of the scale lines 21. The third dovetail tooling 53 and the fourth dovetail tooling 54 are arranged at intervals and are located on the same row of the scale lines 21. Among them, the first dovetail tooling 51 and the second dovetail tooling 52 are arranged on different rows of the scale lines 21 from the third dovetail tooling 53 and the fourth dovetail tooling 54. The groove width D2 of the clamping grooves 503 of the first dovetail tooling 51, the second dovetail tooling 52, the third dovetail tooling 53, and the fourth dovetail tooling 54 is 25 millimeters.

[0050] Among them, the specific structures of the first dovetail tooling 51, the second dovetail tooling 52, the third dovetail tooling 53, and the fourth dovetail tooling 54 can refer to the specific structure of the dovetail tooling described in the second embodiment, and details are not elaborated here. Since the groove width of the clamping grooves 503 of the first dovetail tooling 51, the second dovetail tooling 52, the third dovetail tooling 53, and the fourth dovetail tooling 54 is 25 millimeters, that is, more dovetail toolings 50 can be arranged on the tray 20. Here, the first dovetail tooling 51, the second dovetail tooling 52, the third dovetail tooling 53, and the fourth dovetail tooling 54 are only used to illustrate the number of dovetail toolings. The specific number of dovetail toolings can be set more or less according to the actual situation and the size of the tray 20. In addition, the specific arrangement of the dovetail toolings can also be set to be horizontally arranged or vertically arranged according to the actual situation, and details are not limited here.

[0051]

Fourth Embodiment

[0052] In this embodiment, the machining positioning device is basically the same as that in the first embodiment, and the difference lies in that: the clamping tooling 40 is a vise tooling 60.

[0053] Specifically, as Figure 8As shown, the clamping tooling 40 is a vise tooling 60. The vise tooling 60 includes a second fixed seat 601, a jaw 602, and a positioning block 603. The second fixed seat 601 is detachably connected to the pallet 20. The jaw 602 is disposed on a side of the second fixed seat 601 away from the pallet 20. The positioning block 603 is disposed at one end of a side wall adjacent to the jaw 602. Among them, the jaw 602 is used for clamping a workpiece, and the positioning block 603 is used for positioning the workpiece disposed within the jaw 602.

[0054] In this embodiment, the vise tooling 60 can be, for example, an 8-inch angle-fixed vise. 8 inches means that the maximum opening distance between the jaws of the vise is 8 inches. First, purchase a standard 8-inch angle-fixed vise, and then modify the jaws of the vise. At the same time, calibrate and fix the X-direction (i.e., the horizontal direction or the width direction of the vise) coordinate plane of the jaws on the machine tool to be horizontal, and ensure that the Y-direction (i.e., the vertical direction or the length direction of the vise) coordinate values are consistent. Then, mill steps in the Y / Z coordinate directions of the jaws of the vise. The width of the step in the Y coordinate direction is 3 mm, and the Z-direction (i.e., the height direction of the vise) coordinate is modified into clamping positions with heights of 2 mm, 3 mm, 5 mm, and 8 mm. The left side of the jaw 602 is milled to ensure that the X coordinate values of the left side of the jaw 602 are consistent. A positioning block 603 is installed on the left side of the jaw 602. For each same clamping scenario, it is required to ensure that the X / Y / Z coordinate values of the jaws are consistent to accurately position the workpiece. In this embodiment, one 8-inch modified angle-fixed vise can be installed on each pallet 20. The clamping scenarios of such a vise tooling 60 can be used for the first clamping and processing above the first clamping of the workpiece. Each time one workpiece is clamped, the maximum clamping range of the workpiece is 230×230 mm (length and width dimensions). The incoming workpieces are uniformly square materials, and it is required that the clamping surface is flat. The unilateral machining allowance for the first clamping is ≥1 mm, and the clamping height of the workpiece is ≥2.5 mm. It can be used for clamping workpieces with a machining accuracy of ≥0.03 mm for the second clamping and above.

[0055] In this embodiment, by defining the clamping tooling 40 as the vise tooling 60, modifying the jaws of the 8-inch angle-fixed vise, and unifying the workpieces as square materials, it is possible to process according to the requirements of workpieces suitable for the first clamping and the second clamping or the second clamping and above.

[0056]

Fifth Embodiment

[0057] In this embodiment, the machining positioning device is basically the same as the machining positioning device in the fourth embodiment, and the difference lies in that: the vise tooling 60 includes a first vise tooling 61 and a second vise tooling.

[0058] Specifically, as Figure 9As shown, the vise tooling 60 includes a first vise tooling 61 and a second vise tooling 62. Both the first vise tooling 61 and the second vise tooling 62 are arranged on the tray 20, and the first vise tooling 61 and the second vise tooling 62 are arranged at intervals; wherein, the first vise tooling 61 and the second vise tooling 62 are vise toolings transformed from 6-inch angle-fixed vise toolings.

[0059] First, a standard 6-inch angle-fixed vise can be purchased for jaw transformation. The jaw transformation method is similar to the method of transforming the 8-inch vise in the fourth embodiment above, and will not be elaborated here. Two 6-inch vises can be installed on each tray. This type of vise clamping scenario can be used for processing above the first clamp. At most two workpieces can be clamped at a time. The maximum clamping range of a single 6-inch vise is 180×195mm (length and width dimensions), and the maximum clamping range of a double vise is 450×195mm (length and width dimensions). The incoming workpieces are uniformly square materials, requiring a flat clamping surface, a single-sided machining allowance of the first clamp ≥1mm, a workpiece clamping height ≥2.5mm, and can be used for clamping workpieces with a machining accuracy ≥0.03mm for the second clamp and above.

[0060] In this embodiment, by defining the clamping tooling 40 as the first vise tooling 61 and the second vise tooling 62 of 6-inch angle-fixed type, by transforming the jaws of the 6-inch angle-fixed vise, and by unifying the workpieces as square materials, it can be suitable for processing requirements of workpieces for the first clamp and the second clamp or above the second clamp.

[0061]

Sixth Embodiment

[0062] In this embodiment, the machining positioning device is basically the same as that in the fifth embodiment, and the difference lies in that: the vise tooling 60 is a self-centering vise tooling 63, and the jaw 602 is a quick-change jaw.

[0063] Specifically, as Figure 10 shown, the vise tooling 60 is a self-centering vise tooling 63, and the jaw 602 is a quick-change jaw. The self-centering vise tooling 63 can be obtained, for example, by customizing or transforming a self-centering vise. A self-centering vise is a machine vise for precision machining. Its main feature is that it can drive two jaws to move synchronously relative to each other through a left-right threaded lead screw, so that the clamped workpiece is automatically centered. It can reduce the offset and error that may occur during the clamping of the workpiece. The quick-change jaw belongs to a vise accessory, which allows the operator or on-site installer to quickly replace the jaw part of the vise tooling, thereby improving work efficiency.

[0064] In this embodiment, by customizing the self - centering vise tooling 63 with a precision within 0.01 mm, the self - centering vise tooling 63 can be installed on the pallet 20 through the pin holes 22 and threaded holes 23. According to the size of the self - centering vise tooling 63, 2 or more self - centering vises can be installed on the pallet 20. In this embodiment, 2 self - centering vise toolings 63 are installed on the pallet 20, and the 2 self - centering vise toolings 63 can be arranged at intervals on the pallet 20. The self - centering vise tooling 63 is equipped with standard quick - change jaws, and a positioning block 603 is provided on one side of the self - centering vise tooling 63 to accurately position the workpiece. The clamping scenario of the self - centering vise tooling 63 in this embodiment can be used for the machining of workpieces with the first clamp and above, mainly for the finish machining clamping of workpieces with the second clamp and above. Each time, at least two workpieces can be clamped. The incoming workpieces are uniformly square materials, requiring the clamping surface to be flat, the workpiece clamping height ≥ 2.5 mm, and it can be used for the clamping of workpieces with a machining accuracy ≥ 0.01 mm.

[0065] In this embodiment, through the customization of the self - centering vise tooling 63 and the high - precision positioning installation with the pallet 20 through the pin holes 22 and threaded holes 23, the installation accuracy and installation consistency of the self - centering vise tooling 63 are ensured. The unified workpiece is a square material, which can meet the requirements of finish machining of workpieces and products.

[0066]

Seventh Embodiment

[0067] In this embodiment, the machining positioning device is basically the same as that in the fifth embodiment, and the difference lies in that: the vise tooling 60 is a precision parallel - jaw vise tooling 64, and the jaw 602 is a quick - change jaw.

[0068] Specifically, as Figure 11 shown, the vise tooling 60 is a precision parallel - jaw vise tooling 64, and the jaw 602 is a quick - change jaw.

[0069] The precision parallel - jaw vise is a fixture for precision machining, which has high clamping precision and repeatability.

The jaw 602 is a quick-change jaw with a width of 150. The total length of the main body of the precision parallel jaw vice tooling 64 is 520, and it is accurately and firmly installed on the pallet 20 through the pin hole 22 and the threaded hole 23. Two precision parallel jaw vice toolings 64 are installed on each pallet 20. A positioning block 603 is installed on one side of the jaw of the precision parallel jaw vice tooling 64 to prepare for positioning the workpiece. The clamping scenario of the precision parallel jaw vice tooling 64 can be used for machining workpieces of the first clamp and above, and is mainly used for precision machining and clamping of workpieces of the second clamp or above. At most two workpieces can be clamped each time. The incoming workpieces are uniformly square materials, and it is required that the clamping surface is flat, and the workpiece clamping height ≥ 2.5 mm. It can be used for clamping workpieces with a machining precision ≥ 0.01 mm.
