Technical Field

[0001] The utility model relates to the technical field of intelligent manufacturing, and in particular to a positioning device used in the intelligent manufacturing process. Background Art

[0002] In the field of intelligent manufacturing, positioning devices are often used to clamp and position workpieces (such as pipes, shafts, etc.) so that the workpieces can be fixed in the specified position quickly and accurately.

[0003] In order to improve the production efficiency of intelligent manufacturing and the applicability of the device, some positioning devices can adapt to workpieces of different outer contour sizes for positioning. For example, the Chinese utility model patent with announcement number CN216264742U discloses a positioning device for intelligent manufacturing. The positioning components include a connecting plate, a mounting plate and several positioning arc plates. Several positioning arc plates are provided with positioning cavities, and the diameters of the several positioning cavities gradually increase from the inside to the outside. When positioning workpieces of different sizes, the corresponding positioning arc plate can be selected according to the diameter of the workpiece. The positioning arc plate is pulled out from the connecting plate, and different positioning arc plates can be replaced for use. In addition, multiple positioning arc plates are adhered to each other and installed on the connecting plate, so that the installation position of the positioning arc plate is accurate, and positioning is performed for workpieces of different sizes, thereby improving the applicability of the device, and the clamping and positioning are firm and reliable.

DETAILED DESCRIPTION

[0036] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Reference Figures 1 to 3 The positioning device in some embodiments of the present invention includes a workbench 100 and a positioning assembly 200 .

[0039] The workbench 100 is a horizontal plate-shaped structure having a horizontal supporting top surface 110 . The phrase “being set on the workbench 100 ” mentioned below specifically refers to being set on the horizontal supporting top surface 110 of the workbench 100 .

[0040] Two sets of positioning assemblies 200 are arranged opposite to each other on the workbench 100 . Each positioning assembly 200 includes a sliding seat 210 , a rotating disk 220 , a rotation locking mechanism and a positioning drive mechanism.

[0041] The sliding seat 210 is slidably disposed on the workbench 100 , that is, the sliding seat 210 can slide on the workbench 100 under the action of an external force.

[0042] The rotating disk 220 is rotatably mounted on the sliding base 210 , allowing it to rotate about its own axis on the sliding base 210 under the action of an external force. The rotating disks 220 of the two positioning assemblies 200 are symmetrically arranged; the axial direction of the rotating disk 220 is perpendicular to the workbench 100 , specifically, perpendicular to the horizontal support top surface 110 of the workbench 100 . The rotating disk 220 has a plurality of positioning slots 221 arranged along its circumference on its outer surface. The positioning slots 221 extend axially through the rotating disk 220 .

[0043] The rotation locking mechanism is used to lock the rotating disk 220 after the rotating disk 220 rotates to a desired position. That is, when the rotating disk 220 rotates to a desired position, the rotation locking mechanism can be operated to restrict the rotating disk 220 from rotating further.

[0044] The positioning drive mechanism is provided on the workbench 100 and is used to drive the sliding seats 210 of the two positioning assemblies 200 to move closer or further away, thereby driving the rotating disks 220 of the two positioning assemblies 200 to move closer or further away, thereby achieving clamping, positioning or releasing of the workpiece.

[0045] In some embodiments of the present invention, the positioning device of the two sets of positioning assemblies 200 has a symmetrical arrangement of the rotating disks 220, and the multiple positioning grooves 221 of the two symmetrical rotating disks 220 are also symmetrically arranged one by one. The two symmetrical positioning grooves 221 together enclose a complete clamping and positioning space for the workpiece, and the workpiece can be clamped and positioned by operating the positioning drive mechanism. The positioning grooves 221 of each rotating disk 220 can be designed with different shapes or sizes. When clamping and positioning different workpieces (such as the same workpiece with different outer contour sizes, or workpieces with different outer contour shapes), the corresponding two symmetrical positioning grooves 221 can be selected by rotating the rotating disks 220 of the two sets of positioning assemblies 200. After the rotating disks 220 are rotated into place, the rotating locking mechanism is operated to lock the rotating disks 220. The workpiece clamping and positioning can be completed by operating the positioning drive mechanism without disassembling the rotating disks 220. This adjustment method is more convenient and convenient, greatly improving the workpiece positioning efficiency, and is particularly suitable for the positioning needs of workpieces in the field of intelligent manufacturing.

[0046] In some embodiments of the present invention, since round tube workpieces and cylindrical shaft workpieces are more commonly used in the field of intelligent manufacturing, the multiple positioning grooves 221 of each rotating disk 220 are all arc-shaped grooves with arc-shaped cross sections, such as Figure 1 and Figure 3 As shown, it is suitable for clamping and positioning circular tube workpieces and cylindrical shaft workpieces; and the radius sizes of the multiple positioning grooves 221 of the same rotating disk 220 are different, so the multiple pairs of symmetrical positioning grooves 221 of the two symmetrical rotating disks 220 can enclose multiple workpiece clamping spaces of different diameters, which are suitable for clamping and positioning circular tube workpieces and cylindrical shaft workpieces of different diameters.

[0047] In some embodiments of the present invention, the cross-sectional shapes of the multiple positioning grooves 221 of each rotating disk 220 may also be different, that is, the cross-sectional shapes of the multiple positioning grooves 221 of the same rotating disk 220 are different, then the multiple pairs of symmetrical positioning grooves 221 of the two symmetrical rotating disks 220 can enclose multiple workpiece clamping spaces with different cross-sectional shapes (such as circular, rectangular, triangular, etc.) to be suitable for clamping and positioning workpieces with different cross-sectional shapes.

[0048] In some embodiments of the present invention, each set of positioning assemblies 200 has one rotating disk 220 . To simplify the structure, the total number of rotating disks 220 in the two sets of positioning assemblies 200 is two, which are symmetrically arranged.

[0049] Furthermore, if Figure 3 As shown, the upper surface of each rotating disk 220 is provided with a plurality of slots 222 arranged along the circumference thereof, and the plurality of slots 222 are arranged in a one-to-one correspondence with the plurality of positioning grooves 221 .

[0050] Accordingly, the rotation locking mechanism includes a locking connecting plate 230 and a locking component 240 .

[0051] The locking connecting plate 230 is fixed on the sliding seat 210 so as to be able to slide along with the sliding seat 210 . The locking connecting plate 230 includes a horizontal locking portion 231 extending above the rotating disk 220 .

[0052] The locking component 240 is arranged above the horizontal locking portion 231 and has a plurality of locking pins 241 extending downward and arranged circumferentially. The plurality of locking pins 241 are arranged in a one-to-one correspondence with the plurality of slots 222 , and each locking pin 241 can be inserted into the corresponding slot 222 .

[0053] The horizontal locking portion 231 is provided with an avoidance hole (obstructed, not shown) for the avoidance locking pin 241 to pass through. The avoidance hole is arranged in a one-to-one correspondence with the locking pin 241 and further arranged in a one-to-one correspondence with the slot 222.

[0054] When the rotating disks 220 of the two sets of positioning assemblies 200 are rotated into position, the multiple locking pins 241 of the locking component 240 are aligned with the slots 222 of the rotating disk 220 and inserted into the slots 222. Since the locking connecting plate 230 is fixed to the sliding seat 210, that is, fixed relative to the sliding seat 210, after the multiple locking pins 241 of the locking component 240 are inserted into the slots 222, the rotating disk 220 cannot rotate further under the combined restraining action of the locking connecting plate 230 and the locking pins 241, thus achieving locking. To unlock the rotating disk 220, the locking component 240 is lifted upward to disengage the locking pins 241 from the slots 222.

[0055] In some embodiments of the present invention, the locking connecting plate 230 is an L-shaped plate with a simple structure and easy processing. The bottom end of its vertical part is welded to the sliding seat 210, and the horizontal part constitutes a horizontal locking part 231. The edges of the horizontal locking part 231 are rounded to ensure safe use.

[0056] The locking component 240 may be in the shape of a circular plate or other shapes, the locking pin 241 may be a cylindrical pin, and the slot 222 may be a circular groove, and no specific limitation is made here.

[0057] In some embodiments of the present invention, Figures 1 to 3 As shown, an elastic component 250 is sleeved on the locking pin 241. The elastic component 250 is arranged between the locking component 240 and the horizontal locking portion 231 of the locking connecting plate 230. The two ends of the elastic component 250 are respectively fixed to the locking component 240 and the horizontal locking portion 231.

[0058] When the rotating disk 220 is locked, the locking pin 241 is correspondingly inserted into the slot 222, and the elastic member 250 is slightly compressed under the weight of the locking member 240. When the locking member 240 is lifted upward to release the locking of the rotating disk 220, the locking member 240 pulls the elastic member 250 to deform and elongate. After the locking member 240 is released, the elastic force of the elastic member 250 can drive the locking member 240 to automatically fall back to the locked state, further facilitating the locking operation. At the same time, the elastic member 250 is mounted on the locking pin 241, and can also guide and prevent the lifting and falling of the locking member 240, thereby facilitating operation and improving operational efficiency.

[0059] The elastic component 250 can be a spring or an elastic rubber sleeve, etc., and there is no specific limitation here.

[0060] Furthermore, a handle 242 is provided on the upper surface of the locking component 240 to facilitate lifting the locking component 240 upward when unlocking.

[0061] Regarding the positioning drive mechanism, in some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, it includes a limiting frame 260 and a driving bolt 270.

[0062] The limiting frame 260 is fixed to the workbench 100 and includes a drive mounting plate 261 and two opposing limiting plates 262. Both the drive mounting plate 261 and the limiting plates 262 are fixed to the workbench 100. The sliding seat 210 is located between the two limiting plates 262 and slidably engages with the limiting plates 262. The two limiting plates 262 form a sliding channel for the sliding seat 210, and the two limiting plates 262 limit and guide the sliding of the sliding seat 210.

[0063] The driving bolt 270 is rotatably set on the driving mounting plate 261 and extends along the sliding direction of the sliding seat 210. The driving bolt 270 passes through the driving mounting plate 261, and its head end and tail end are respectively located on opposite sides of the driving mounting plate 261, and the sliding seat is located on the side where the tail end of the driving bolt 270 is located, that is, the head end of the driving bolt 270 and the sliding seat 210 are respectively located on opposite sides of the driving mounting plate 261, and the tail end of the driving bolt 270 is threadedly connected to the sliding seat 210.

[0064] Specifically, a mounting hole is formed on the drive mounting plate 261, through which the drive bolt 270 is mounted. A bearing is provided between the mounting hole and the drive bolt 270, so that the drive bolt 270 can only rotate relative to the drive mounting plate 261 and cannot move axially. When the drive bolt 270 is rotated, due to its threaded connection with the sliding seat 210, and the sliding seat 210 is limited and guided by the limiting plates 262 on both sides, the drive bolt 270 rotates and drives the sliding seat 210 to slide, thereby driving the rotating disk 220 and the sliding seat 210 to move together, causing the rotating disks 220 of the two positioning assemblies 200 to move closer or farther away, thereby clamping, positioning, or releasing the workpiece.

[0065] Furthermore, the limiting plate 262 and the sliding seat 210 are provided with mutually cooperating sliding guide structures to further improve the sliding guiding stability and reliability of the limiting plate 262 on the sliding seat 210 .

[0066] Specifically, if Figure 1 and Figure 3 As shown, the sliding guide structure can be a raised guide rail 263 formed on the side of the limiting plate 262 and a corresponding recessed slideway formed on the side of the sliding seat 210 (not shown in the figure due to viewing angle reasons). Of course, the sliding guide structure can also be in other forms, and no specific restrictions are made at this moment.

[0067] In some embodiments of the present invention, one end of the limiting plate 262 is connected to the driving mounting plate 261 and the other end is a free end. A limiting structure 264 is provided on the free end of the limiting plate 262 to prevent the sliding seat 210 from sliding off the limiting plate 262.

[0068] like Figure 3 As shown, the limiting structure 264 is a limiting protrusion formed on the free end of the limiting plate 262, which serves as a stop and limit for the sliding seat 210, preventing the sliding seat 210 from sliding out of the free end of the limiting plate 262 and separating from the limiting plate 262, thereby ensuring reliable use.

[0069] In some embodiments of the present invention, the two sets of positioning assemblies 200 are symmetrically arranged, that is, the two sets of positioning assemblies 200 have exactly the same structure, which facilitates processing, assembly and operation.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
