Description

Technical Field

[0001] This utility model relates to the field of plastic tooling technology, and more specifically, to a rotary deburring tooling. Background Technology

[0002] Plastic parts refer to plastic product components manufactured through plastic molding processes. It is a general term for plastic products with specific shapes, sizes, and functions, which are obtained by heating, pressurizing, and injecting plastic raw materials (such as granules or powders) into molds through a series of processes.

[0003] Currently, burrs are frequently generated after the molding of plastic products. Burrs are a common defect in the production of plastic products. They not only affect the appearance of the product, but may also affect its performance and service life. Therefore, during the processing of plastic products, it is necessary to remove surface burrs by tooling scraping or grinding. However, the burrs generated by plastic products are usually irregular in shape. Most existing burr scraping tooling is difficult to control the force during burr removal. Excessive force can easily damage the plastic product, while insufficient force will result in incomplete burr removal. Therefore, this utility model proposes a rotary burr scraping tooling. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a rotary deburring fixture, which aims to solve the problem that existing deburring fixtures are difficult to control the force during deburring, as excessive force can easily damage the plastic parts, while insufficient force will result in incomplete deburring.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A rotary deburring fixture includes a machine base, a drive motor fixedly connected inside the machine base, a hollow rotary platform fixedly connected to the top of the machine base, and the output end of the drive motor extending into the hollow rotary platform. A mold base is fixedly connected to the output end of the hollow rotary platform. Two rotary clamping cylinders are fixedly connected inside the mold base, and the tops of both rotary clamping cylinders extend to the upper side of the mold base. A fixed base is fixedly connected to the top of the machine base, and a rotating rod is rotatably connected to the top of the fixed base via a rotating shaft. A scraper is detachably connected to one end of the rotating rod near the mold base. A counterweight assembly is provided on the rotating rod and the fixed base to assist the scraper in contacting the product.

[0009] As a preferred embodiment of this utility model, the counterweight assembly includes a weighing pan, a counterweight, and a lifting cylinder. The weighing pan is rotatably connected to the end of the rotating rod away from the mold base via a rotating shaft. The counterweight is disposed on the weighing pan. The lifting cylinder is fixedly connected to a fixed base, and the output end of the lifting cylinder corresponds to the rotating rod.

[0010] As a preferred embodiment of this utility model, the weighing pan is fixedly connected with multiple limiting rods, and the counterweight is located between the multiple limiting rods.

[0011] As a preferred embodiment of this utility model, a waste box is provided at the top of the machine, and the waste box corresponds to the scraper.

[0012] As a preferred embodiment of this utility model, a flange adapter is fixedly connected between the output end of the hollow rotating platform and the bottom end of the mold base.

[0013] As a preferred embodiment of this utility model, a hollow tube is fixedly connected inside the machine base, and the top end of the hollow tube passes through the hollow rotating platform and the flange adapter plate in sequence and is located inside the mold base. A slip ring is fixedly connected to the top end of the hollow tube and is located inside the mold base.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) In this solution, the plastic part is fixed on the mold base by two rotary clamping cylinders. The hollow rotating platform drives the mold base to rotate by controlling the drive motor. By placing counterweights in the weighing pan, the counterweights cause the rotating rod to lift the scraper upward and contact the surface of the plastic part under the action of gravity. The output end of the lifting cylinder extends upward and contacts the rotating rod, limiting the upward rotation angle of the rotating rod, so that the maximum upward rotation angle of the scraper is kept fixed, effectively avoiding damage to the plastic part caused by excessive force on the scraper. At the same time, the counterweights in the weighing pan exert force on the rotating rod, so that the scraper always keeps in contact with the surface of the plastic part, preventing the scraper from having too little contact force with the plastic part, resulting in incomplete removal of burrs.

[0025] Example:

[0026] Please see Figure 1-3A rotary deburring fixture includes a machine base 1, a drive motor 2 fixedly connected inside the machine base 1, a hollow rotary platform 3 fixedly connected to the top of the machine base 1, and the output end of the drive motor 2 extending into the hollow rotary platform 3. A mold base 4 is fixedly connected to the output end of the hollow rotary platform 3. Two rotary clamping cylinders 5 are fixedly connected inside the mold base 4, and the top ends of the two rotary clamping cylinders 5 extend to the upper side of the mold base 4. A fixed seat 6 is fixedly connected to the top of the machine base 1. A rotating rod 7 is rotatably connected to the top of the fixed seat 6 via a rotating shaft. A scraper 8 is detachably connected to one end of the rotating rod 7 near the mold base 4. A counterweight assembly 9 is provided on the rotating rod 7 and the fixed seat 6. The counterweight assembly 9 is used to assist the scraper 8 in contacting the product.

[0027] In this embodiment, when deburring the plastic product, the plastic product is placed on the mold base 4, and two rotary clamping cylinders 5 clamp and fix the plastic product. The counterweight component 9 adjusts the rotation angle of the rotating rod 7 on the fixed seat 6, so that the position of the scraper 8 is controlled within the required range to contact the plastic product. Then, the drive motor 2 is started, and the drive motor 2 controls the hollow rotating platform 3 to rotate the mold base 4. The mold base 4 drives the clamped plastic product to rotate. When the plastic product rotates, its surface contacts the scraper 8, and the scraper 8 removes the burrs on the surface of the plastic product.

[0028] Specifically, the counterweight assembly 9 includes a weighing pan 91, a counterweight 92, and a lifting cylinder 93. The weighing pan 91 is rotatably connected to the end of the rotating rod 7 away from the mold base 4 via a rotating shaft. The counterweight 92 is set on the weighing pan 91. The lifting cylinder 93 is fixedly connected to the fixed base 6, and the output end of the lifting cylinder 93 corresponds to the rotating rod 7.

[0029] In this embodiment, by adding a counterweight 92 to the weighing pan 91, the rotating rod 7 is subjected to force and rotates. The rotating rod 7 drives the scraper 8 to rotate upward and contact the surface of the plastic product. The lifting cylinder 93 can limit the upward rotation angle of the rotating rod 7 by controlling the extension and retraction of the output end, so that the scraper 8 always contacts the surface of the plastic product under the counterweight 92, and at the same time, it will prevent the scraper 8 from rotating upward too much and damaging the plastic product.

[0030] Specifically, multiple limit rods 10 are fixedly connected to the weighing pan 91, and the counterweight 92 is located between the multiple limit rods 10.

[0031] In this embodiment, multiple limiting rods 10 are used to limit the counterweight 92 and prevent the counterweight 92 from falling off the weighing pan 91.

[0032] Specifically, a waste box 11 is provided at the top of the machine 1, and the waste box 11 corresponds to the scraper 8.

[0033] In this embodiment, the waste box 11 is located below the scraper 8 and can collect the waste generated by the scraper 8 scraping the surface of the molded product.

[0034] Specifically, a flange adapter plate 12 is fixedly connected between the output end of the hollow rotary platform 3 and the bottom end of the mold base 4.

[0035] In this embodiment, the flange adapter plate 12 is used to connect the hollow rotating platform 3 and the mold base 4, so that the hollow rotating platform 3 can stably drive the mold base 4 to rotate.

[0036] Specifically, a hollow tube 13 is fixedly connected inside the machine base 1, and the top end of the hollow tube 13 passes through the hollow rotating platform 3 and the flange adapter plate 12 in sequence and is located inside the mold base 4. A slip ring 14 is fixedly connected to the top end of the hollow tube 13 and is located inside the mold base 4.

[0037] In this embodiment, the hollow tube 13 is used to support the slip ring 14, so that the slip ring 14 is kept fixed in the mold base 4, and to supply energy and signals to the two rotary pressing cylinders 5, thereby realizing the control of the two rotary pressing cylinders 5.

[0038] Working principle: When deburring plastic parts, the plastic parts are placed on the mold base 4 and clamped in place by two rotary clamping cylinders 5. By adding counterweights 92 into the weighing pan 91, the rotating rod 7 is rotated under force. The rotating rod 7 drives the scraper 8 to rotate upward and contact the surface of the plastic parts. The lifting cylinder 93 limits the upward rotation angle of the rotating rod 7 by controlling the extension and retraction of the output end, so that the scraper 8 is always in contact with the surface of the plastic parts under the action of the counterweights 92. Then, the drive motor 2 is started, and the drive motor 2 controls the hollow rotating platform 3 to rotate the mold base 4. The mold base 4 drives the clamped plastic parts to rotate. When the plastic parts rotate, their surface contacts the scraper 8, and the scraper 8 removes the burrs from the surface of the plastic parts.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
