Description

Technical Field

[0001] The utility model relates to the technical field of glass mould processing, in particular to a clamp for processing the outer circle of a glass mould. Background Art

[0002] The concept of the outer circle of the glass mold refers to the back of the glass mold, that is, the surface facing outward when in use, that is, the surface facing away from the mold cavity; the aforementioned glass mold outer circle processing items are not limited to milling the outer circle, milling the edge, engraving the outer circle, opening the wear plate groove cavity, opening the vest eye, etc.

[0003] The existing tooling fixtures for processing the outer circle of glass molds do not have a good clamping effect, and excessive clamping force can easily cause damage to the glass mold, affecting the processing quality.

[0004] For example, a tooling fixture for outer circle processing of a glass mold disclosed in Chinese patent CN216178617U can clamp the glass mold through a first limit clamp on one side of the tailstock mechanism and a second limit clamp on one side of the first fixed block. At the same time, the second limit clamp is connected to the first fixed block through a connecting rod and a hollow cylinder. At the same time, the force received by the second limit clamp will be transmitted to the second movable block inside the hollow cylinder through the connecting rod, and the spring on one side is squeezed by the second movable block, and the reaction force of the spring being squeezed is offset, so that the force transmitted by the second limit clamp can be reduced, thereby reducing the pressure on the glass mold. By installing a first motor on one side of the top of the workbench, the first motor is started by an external controller, so that the spiral shaft can be driven to rotate, and the first movable block on the spiral shaft can be freely moved on the spiral shaft. At the same time, the top of the first movable block is fixedly connected to a bearing seat, and a glass mold is movably connected to the bearing seat. The movement of the first movable block can drive the bearing seat and the glass mold to move, and complete the automatic discharge after the mold processing.

[0005] However, it is inconvenient to replace the bearing seat during use of the device. Long-term use of the bearing seat causes wear on the contact surface between the bearing seat and the glass mold, thereby scratching the surface of the glass mold and affecting the production quality of the glass mold.

[0006] For this reason, we urgently need to provide a kind of glass mold outer circle processing fixture. Utility Model Content

[0007] The purpose of the utility model is to provide a fixture for processing the outer circle of a glass mold, so as to solve the problem proposed in the above-mentioned background technology that it is inconvenient to replace the bearing seat during use, and the contact surface between the bearing seat and the glass mold is worn due to long-term use, thereby causing scratches on the surface of the glass mold, affecting the production quality of the glass mold.

[0011] Preferably, the moving unit comprises a motor, a threaded rod and a bearing, the motor is fixedly mounted on the top of the workbench at the back of the shell, and the bearing is fixedly mounted at the front end inside the shell.

[0012] Preferably, the clamping unit comprises a telescopic member and a clamping plate, the telescopic member is fixedly mounted on the left and right sides of the front end of the workbench, and the clamping plate is mounted on the output end of the telescopic member.

[0013] Preferably, positioning holes with a diameter equal to that of the connecting rod are formed around the upper surface of the moving block, and the connecting rod is connected to the positioning holes, so as to facilitate the installation of the bearing seat on the top of the moving block.

[0014] Preferably, connecting holes with the same diameter as the clamping rod are opened on the left and right sides of the upper end of the moving block, and a clamping hole with the same diameter as the clamping rod is opened at the lower end of the connecting rod. The clamping rod passes through the connecting hole and is clamped with the clamping hole, thereby fixing the bearing seat on the top of the moving block.

[0016] Preferably, a rubber pad is fixedly mounted on a side of the clamping plate away from the telescopic member, so as to prevent the glass mold from being scratched when the clamping plate clamps the glass mold.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The fixture for processing the outer circle of the glass mold is provided with a replacement unit. When the bearing seat needs to be replaced, the left and right pull rods are pulled outward, and the pull rods drive the retaining ring and the clamping rod to move until the clamping rod is disengaged from the clamping hole formed by the connecting rod. The bearing seat is then pulled upward to remove the bearing seat. Then the connecting rod at the bottom of the bearing seat to be replaced is inserted into the positioning hole. The pull rod is then released, and the retaining ring is pushed under the action of the spring to drive the clamping rod to penetrate the connecting hole and engage with the clamping hole, thereby fixing the bearing seat on the top of the moving block, thereby completing the replacement of the bearing seat. This solves the problem that it is inconvenient to replace the bearing seat during use, as proposed in the background technology, and the contact surface of the bearing seat and the glass mold is worn due to long-term use, thereby scratching the surface of the glass mold and affecting the production quality of the glass mold.

[0019] 2. The fixture for processing the outer circle of the glass mold is provided with a moving unit, and the motor is started to drive the threaded rod to rotate. When the threaded rod rotates, it is threadedly connected with the moving block, so that the moving block drives the glass mold on the top of the bearing seat to move back and forth, which is convenient for discharging after the mold is processed.
