Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a tooling fixture for automatically processing a mold core of a PPR water supply pipe mouth mold. Background Art

[0002] The mold core used in the production process of PPR water pipes is made of material rods. During processing, it needs to be transferred neatly and orderly between equipment. At present, most of the rod material discharge or feeding operations are to place the rods on the material plate first, and then clamp the rods with clamps. However, the existing clamps cannot firmly grasp the rods, which makes the rods easy to fall off during transportation.

[0003] In response to the above problems, the utility model patent document with authorization announcement number CN212666617U discloses a bar clamping fixture, which is fixedly connected to the clamping main aluminum plate at one end of the main arm, and a plurality of bar accommodating grooves arranged at intervals are opened on the top surface of the clamping main aluminum plate, and the bar accommodating grooves extend through the surface of the clamping main aluminum plate along the width direction of the clamping main aluminum plate, and a slidable clamping hook is arranged on the adjacent side of the clamping main aluminum plate, and a hook groove corresponding to the bar accommodating groove is arranged on the clamping hook. A translation cylinder is also arranged on the clamping main aluminum plate to drive the clamping hook to slide relative to the clamping main aluminum plate, thereby clamping or releasing the bar placed in the bar accommodating groove. A lifting cylinder is also installed on the main arm, and the piston rod of the lifting cylinder is downwardly connected to a lifting rack, and the lifting rack is provided with fixed pressure blocks corresponding to the bar materials one by one, so as to tightly fix the bar materials in the bar accommodating groove, thereby ensuring that the bar materials do not fall off during transportation.

[0004] However, when the above-mentioned clamping fixture is in use, the bar is placed horizontally on the clamping main aluminum plate, and in subsequent processing, the bar needs to be clamped vertically on the chuck of the CNC lathe. At this time, it is necessary to adjust the direction of the bar on the clamping main aluminum plate and correct the position of the bar to meet the processing requirements. The process of adjusting the direction of the bar increases the complexity of its processing, increases the time consumed in processing the bar, and reduces the processing efficiency of the mold core. Utility Model Content

[0005] The utility model provides a tooling fixture for automatically processing a PPR water supply pipe mouth mold core, so as to solve the technical problem in the prior art that the unreasonable placement of rods leads to an increase in the time consumed in processing the rods and further leads to a decrease in the processing efficiency of the mold core.

[0006] In order to solve the above problems, the tooling fixture for automatically processing the PPR water supply pipe mouth mold core provided by the utility model adopts the following technical solutions:

[0011] The beneficial effects of the fixture for automatically processing the core of the PPR water supply pipe mouth mold provided by the utility model are as follows: by setting a plurality of self-centering structures on the pallet, a manipulator can be used to vertically place a bar with an information identification code on the self-centering structure, and the self-centering structure can be used to automatically align the bar to the center position and constrain the lower part of the bar loaded into the self-centering structure; by installing a spring telescopic bracket on the pallet, the upper part of the bar is constrained by the upper constraint component of the spring telescopic bracket to prevent it from shifting during transportation; the telescopic structure of the spring telescopic bracket can move down when the manipulator places the clamped bar on the self-centering structure, so as to place the bar and ensure that the self-centering structure can center the bar, and automatically move up after the bar is placed to ensure that the upper constraint component constrains the bar. Through the above-mentioned settings, the utility model effectively solves the technical problem that the placement of the bar in the prior art is unreasonable, which leads to an increase in the time spent on processing the bar, and then reduces the processing efficiency of the core.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0031] It should be noted that the main concept of the tooling fixture for automatically processing the PPR water supply pipe mouth mold core provided by the utility model is: by arranging a self-centering structure on the pallet, a spring telescopic bracket is installed on the side of the self-centering structure, and the spring telescopic bracket includes a telescopic structure and an upper constraint assembly. When in use, the rod with the information identification code is clamped by a robot, and the rod is placed in the self-centering structure. At this time, the telescopic structure is compressed so that the self-centering structure can center the rod. After that, the robot moves up, the telescopic structure returns to its original position, and the upper constraint assembly constrains the upper part of the rod, thereby ensuring that the rod is placed vertically on the pallet and limiting the horizontal displacement of the rod.

[0032] After introducing the basic principle of the utility model, various non-limiting embodiments of the utility model are specifically introduced below. Any number of elements in the drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0033] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0036] About the self-centering structure. The self-centering structure includes a bottom plate 9, a top plate 10, and a square plate 13 arranged between the bottom plate 9 and the top plate 10. The bottom plate 9 is provided with three arc-shaped installation grooves 11 evenly spaced, the top plate 10 is provided with three U-shaped grooves 12 opening outward, and the square plate 13 is provided with straight grooves 14 corresponding to the U-shaped grooves 12. Each arc-shaped installation groove 11 is provided with a limiter 15 penetrating the arc-shaped installation groove 11, the straight groove 14 and the U-shaped groove 12 to limit the horizontal movement of the rod 2 loaded into the self-centering structure.

[0037] Specifically, the bottom plate 9 and the top plate 10 are both circular structures, and the diameter of the top plate 10 is smaller than the side length of the square plate 13 .

[0038] Specifically, corresponding pin holes are opened in the central parts of the bottom plate 9, the top plate 10 and the square plate 13, and a relatively rotatable connection between the bottom plate 9, the top plate 10 and the square plate 13 is achieved by a pin shaft penetrating the pin hole.

[0039] About the spring telescopic bracket. The spring telescopic bracket includes telescopic structures installed on two opposite sides of the self-centering structure, the top ends of the telescopic structures are connected through an upper restraining assembly, and a circular hole is opened in the center of the upper restraining assembly to install the rod 2 and restrain the upper part of the rod 2.

[0040] Specifically, the telescopic structure includes a supporting top rod 3, a supporting bottom rod 4 and a spring assembly installed on the peripheral side of the self-centering structure. The supporting top rod 3 and the supporting bottom rod 4 are connected by a cross-arranged first diagonal rod 5 and a second diagonal rod 6. The spring assembly includes four positioning columns 7 installed at the bottom of the upper constraint assembly and extending downward to pass through the pallet 1, and a spring (not shown in the figure) mounted on the positioning column 7. The spring is located between the upper constraint assembly and the pallet 1.

[0041] Specifically, a horizontally extending slot 8 is respectively provided on the support top rod 3 and the support bottom rod 4, and the two slots 8 correspond to each other up and down. One end of the first inclined rod 5 is fixed on the support top rod 3, and the other end thereof is slidably installed in the slot 8 of the support bottom rod 4.

Four positioning columns 7 are installed at the bottom of the square base plate 21.

[0043] Specifically, four positioning columns 7 are respectively installed at four corners of the square bottom plate 21 .

[0044] About the lifting structure: The lifting structure includes a support frame 16 and a workbench 17 horizontally arranged at the upper end of the support frame 16 , and the workbench 17 is used to place the pallet 1 .

[0045] Specifically, two corresponding top guide columns 18 are installed on the workbench 17, and a conical guide sleeve 23 corresponding to the two top guide columns 18 is arranged on the bottom surface of the tray 1. A motor 19 connected to the top guide columns 18 is also installed on the support frame 16.

[0046] Specifically, the workbench 17 is a rectangular structure, and each of the four corners of the bottom surface is provided with an auxiliary lifting column 20 extending downward to increase the lifting force of the workbench 17 .

[0047] The working principle of the fixture for automatically processing the core of the PPR water supply pipe mouth mold provided by the utility model is as follows: the bar material 2 with the bar code attached is placed vertically according to certain rules and sequence, then the manipulator grabs the bar material 2 and automatically identifies the bar code on the bar material 2, and transfers the bar material 2 to the self-centering device on the tray 1. At this time, the manipulator presses down the upper constraint component, and the spring is compressed to place the bar material 2. After the manipulator is removed, the spring drives the upper constraint component to return to its original position under the action of the elastic force, and then moves the limiter 15 and the baffle 22 to make them close to the bar material 2, so as to complete the centering of the bar material 2 and form a constraint on the bar material 2;

[0048] Finally, the pallet 1 is transported to the lineside warehouse for storage by the automatic transport AGV forklift. After the pallet 1 is placed on the workbench 17 of the jacking structure, the top guide column 18 moves upward under the drive of the motor 19 and reaches the center position of the conical guide sleeve 23, thereby completing the precise positioning of the pallet 1, thereby ensuring that when the bar 2 is clamped subsequently, the robot can quickly and accurately grab the bar 2.
