[0002] Casting machine refers to a special equipment for making cast film. Its basic principle is to evenly apply liquid material on a flat surface through tools such as rollers or scrapers, and form a uniform and continuous film after drying. The casting machine is equipped with many different rollers such as transmission rollers, feed rollers, winding rollers and other structural components. Therefore, based on the requirement of convenience, tooling fixtures are also required in the process of assembling and producing the casting machine.

[0003] In the prior art, the structural components of the tape casting machine to be assembled can be transferred to the part to be installed by using a fixture, and then assembled manually, which is more convenient to operate. However, most of the fixtures on the market are single-shaped and non-adjustable, which makes it difficult to effectively apply to the clamping and transfer assembly of different rollers and other structural components, and will also prolong the assembly time of the tape casting machine and reduce the assembly efficiency. Therefore, it is urgent to improve the existing tape casting machine assembly fixture and provide a more applicable fixture for tape casting machine assembly. Utility Model Content

Three groups of clamping assemblies 8 are respectively slidably connected in the three radial through grooves 7 and can move away from or approach each other, and are used to clamp the parts to be assembled of the casting machine.

[0028] In this embodiment, the steering adjustment assembly 9 is used to adjust the states of the two first clamping columns 5 and the corresponding two groups of clamping assemblies 8 according to the shape of the clamped structural component, which has a wider application range and stronger practicality.

[0029] As a preferred embodiment, on the basis of the above structure, further, a fixing frame 10 is fixedly connected to the rear end outer walls of the two first clamping columns 5 and the second clamping column 6 .

[0030] As a preferred embodiment, on the basis of the above structure, the clamping assembly 8 further includes a clamping arm 81, an anti-slip pad 82, a support block 83, an oblique brace 84, a servo motor 85 and a screw 86. The clamping arm 81 is slidably located on the inner side of the radial through groove 7, and the anti-slip pad 82 is bonded to one side of the front end of the clamping arm 81. The middle part of the side of the clamping arm 81 facing away from the anti-slip pad 82 is fixedly connected with a support block 83, and an oblique brace 84 is fixedly connected between the support block 83 and the front end of the clamping arm 81.

The rear end of the clamping arm 81 is threadedly sleeved on the outer side of the screw 86.

[0031] In this embodiment, the rotation of the screw rod 86 is controlled by the servo motor 85, so that the clamping arms 81 can be controlled to slide stably along the corresponding radial through grooves 7. By synchronously retracting the multiple clamping arms 81, the roller components can be clamped and transferred for assembly.

[0032] As a preferred embodiment, on the basis of the above structure, further, the anti-slip pad 82 is made of rubber, and convex structures are evenly distributed on its outer surface.

[0033] In this embodiment, the anti-slip pad 82 made of rubber can increase the frictional force between the structural member and the clamping arm 81, and further increase the clamping stability.

[0034] As a preferred embodiment, on the basis of the above structure, further, the clamping arm 81, the support block 83 and the diagonal brace 84 form a triangular structure. The support block 83 fits and slides on the outer surface of the second clamping column 6, and the width of the support block 83 is greater than the width of the radial through groove 7.

[0035] In this embodiment, it is convenient to transfer the rebounding force received by the clamping arm 81 when clamping the component to the first clamping column 5 and the tooling platform 4, so as to achieve the purpose of improving the strength of the clamping arm 81 and avoiding bending deformation.

[0036] As a preferred embodiment, on the basis of the above structure, further, the steering adjustment assembly 9 includes an electric telescopic rod 91, a rack 92 and a gear ring 93. The electric telescopic rod 91 is fixedly installed on the rear outer wall of the top of the tooling platform 4.

The left and right sides of the rack 92 are respectively meshed with two gear rings 93, and the two gear rings 93 are respectively fixedly sleeved on the outer sides of the rear ends of the two first clamping columns 5.

[0037] In this embodiment, by contracting the electric telescopic rod 91 and driving the rack 92 to move upward, the two gear rings 93 can be used to drive the two first clamping columns 5 and the corresponding two groups of clamping assemblies 8 to rotate respectively, so that the two clamping arms 81 above are on the same horizontal straight line, which is convenient for realizing the stable clamping of other structural components.

[0038] The working principle of the present utility model is as follows:

[0039] When in use, first install the connecting plate 2 on the existing robotic arm 1, use the robotic arm 1 to transfer the tooling fixture to the calender roll component to be clamped and taken, and make one end of the roll component located between multiple clamping arms 81. Then, multiple servo motors 85 can be started synchronously. By using the rotating lead screw 86 to control the stable movement of the clamping arm 81 inside the radial through groove 7, and by controlling the synchronous closing of the multiple annularly distributed clamping arms 81, the effective clamping of the roll component can be realized. Moreover, the anti-slip pad 82 made of rubber can also increase the frictional force between the structural component and the clamping arm 81, further increasing the clamping stability. Then, use the robotic arm 1 to transfer the roll component to the installation position on the calender frame, and manual installation can be carried out by using existing means;

[0040] When assembling other structural components such as a square for a casting machine that need to be clamped, the electric telescopic rod 91 can be used to control the rack 92 to move upward, so that the two gear rings 93 drive the two first clamping columns 5 and the corresponding two groups of clamping components 8 to rotate to the state shown in Figure 5 the figure, so that the two upper clamping arms 81 are on the same horizontal straight line. At this time, other structural components such as a square can be supported above the bottom clamping arm 81, and the two upper clamping arms 81 can be controlled separately to approach each other, which is convenient for realizing the stable clamping of other structural components, and then the transfer and assembly can be carried out;

[0041] In summary, the present tooling fixture can adjust the state of the clamping component 8 according to the shape of the clamped structural component, has a wider application range and stronger practicability. Moreover, during the clamping and transfer process of the structural component, by using the diagonal brace 84 and the support block 83 that always fits the surface of the first clamping column 5, it is convenient to transfer the rebounding force received by the clamping arm 81 to the first clamping column 5 and the tooling platform 4, which can achieve the purpose of improving the strength of the clamping arm 81 and avoiding bending deformation, and can ensure the stable clamping and transfer assembly of the structural component, facilitating the stable assembly of the casting machine;

[0042] It should be further noted that the circuit connection and specific control method of the driving servo motor 85 and the electric telescopic rod 91 in the present tooling fixture can be controlled by a dedicated PLC controller. This part adopts existing mature means and is not the scope protected by this case, so it will not be elaborated here.
