Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment, and in particular to a deburring fixture for cup rims. Background Technology

[0002] Deburring of cups is usually done manually by operators. To improve efficiency, some manufacturers use semi-automatic tooling for deburring. For example, the patent application number CN202420111556.7 discloses a deburring mechanism for plastic products, which uses a suction cup to detachably adsorb a grinding disc for deburring. However, in this type of deburring mechanism, the grinding disc is a consumable part that needs to be replaced frequently, and each replacement requires replacing the entire grinding disc, which is costly. Utility Model Content

[0003] This invention provides a cup deburring fixture with a simple structure. The grinding blocks can be selectively replaced instead of all modules, thereby reducing the cost of use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cup deburring fixture, comprising a base, a cup body placement seat disposed in the middle of the base, a gantry frame disposed on the outside of the base, a lifting driver disposed on the gantry frame, a lifting plate disposed at the output end of the lifting driver, a rotary driver disposed on the lifting plate, and a deburring head disposed at the output end of the rotary driver. The deburring head is located above the cup body placement seat, and the bottom of the deburring head is provided with a plurality of conical cavities. The bottom of the conical cavities protrudes through the bottom of the deburring head, and a grinding block is detachably disposed in the conical cavity. The bottom of the grinding block protrudes from the bottom surface of the deburring head.

[0005] In the above solution, the deburring head of this utility model is rotatable and can use the grinding blocks on the deburring head to deburr. The number of grinding blocks is multiple rather than a whole, so each time the grinding blocks need to be replaced, it is not necessary to replace all the grinding blocks. Instead, the grinding blocks with more severe wear can be selectively replaced, which reduces the material cost.

[0006] In one embodiment, the cup holder includes a fixed block and a movable block, each of the fixed block and the movable block having an arc-shaped notch. The base is provided with a drive cylinder for driving the movable block toward or away from the fixed block, and the movable block is connected to the output end of the drive cylinder.

[0007] In the above scheme, the driving cylinder can drive the movable block to approach the fixed block, so that the arc-shaped notches on the movable block and the fixed block can be inserted into the cup body to be deburred placed on the cup body placement seat.

[0008] In one embodiment, the gantry includes a top plate, the lifting drive is mounted on the top plate, the output end of the lifting drive passes downward through the top plate, and the top plate is provided with a clearance through hole for the installation of the rotary drive.

[0009] In the above scheme, the lifting drive is located on the side of the top plate, while the rotary drive is centrally located above the cup holder. Through the action of the lifting drive and the rotary drive, the deburring head can be lifted and rotated; both the lifting drive and the rotary drive can be motors or cylinders.

[0010] In one embodiment, the gantry includes side columns, and the inner side of the side columns is provided with guide rails that slide in cooperation with the lifting plate.

[0011] In one embodiment, the bottom of the deburring head is provided with four conical cavities arranged in a circumferential array, and the conical cavities are in the shape of a frustum cone.

[0012] In the above scheme, the conical cavity is a horizontally placed truncated cone shape, and the bottom of the conical cavity passes through the bottom surface of the burr head to form a triangular or solid-shaped notch. The grinding block is a truncated cone shape that matches the shape of the conical cavity. The grinding block is placed horizontally and the bottom of the grinding head passes through it. The part that passes through can be deburred by rotating after contacting the cup body. The grinding block can be a conventional part used for deburring, such as a grinding stone.

[0013] In one embodiment, the outer diameter of the conical cavity is smaller than the inner diameter.

[0014] In one embodiment, the deburring head is a rubber block.

[0015] In the above scheme, the deburring head is made of a malleable rubber material, which allows the grinding block to be easily installed into the conical cavity.

[0016] In one embodiment, the deburring head is frustum-shaped. Attached Figure Description
