Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tools, in particular to a dustproof device for a quick-change clamping fixture. Background Art

[0002] Many zero-point positioning devices on the market are not sealed. During processing, the environment inside the machine tool is relatively harsh, and iron filings will move randomly with water, air and the operation of the machine tool. When a workpiece on a pallet is processed and taken out, there will be iron filings and residues left over from the last processing on the surface of the zero-point positioning device in the machine tool. If the operator does not intervene, when the next pallet is put on the machine, the accuracy of its XYZ axis relative to the XYZ axis of the machine tool cannot be guaranteed, which seriously affects the yield rate of the product; in addition, residual iron filings in the clamping device can easily affect the degree of automation of the flexible processing production line. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a dustproof device for a quick-change clamping fixture, which effectively solves the problems raised in the above background.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dust-proof device for a quick-change clamping fixture, comprising a workbench, a zero-point positioning mounting plate is installed at the upper end of the workbench, a zero-point positioning device is evenly embedded at the upper end of the zero-point positioning mounting plate, a sealing ring mounting plate is provided on the outside of the zero-point positioning mounting plate, a sealing ring is embedded inside the upper end of the sealing ring mounting plate, and a tray is provided at the upper end of the sealing ring.

[0005] Preferably, the outer wall of the zero-point positioning mounting plate is provided with connecting holes all around, the lower end of the sealing ring mounting plate is provided with connecting grooves all around, and the sealing ring mounting plate and the zero-point positioning mounting plate are positioned by connecting with screws passing through the connecting grooves and the connecting holes.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] 1. The utility model has a simple structure, convenient maintenance and good interchangeability. It only needs to clamp the sealing ring on the sealing ring mounting plate without opening a mold. The sealing ring is a consumable part. The new model adopts universal accessories to reduce the subsequent maintenance cost and effectively reduce the generation of iron filings on the zero-point positioning device, improve the accuracy of the tray after clamping, and reduce the risk of defective products.

[0008] 2. This new type improves the stability of the zero-point positioning device, increases the automation rate of the equipment, improves production efficiency, reduces waiting waste, saves production costs, and reduces the rhythm of manual participation. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0015] Embodiment 1, by Figure 1-Figure 2 The utility model comprises a workbench 1, a zero-point positioning mounting plate 2 is mounted on the upper end of the workbench 1, a zero-point positioning device 3 is evenly embedded on the upper end of the zero-point positioning mounting plate 2, a sealing ring mounting plate 4 is sleeved on the outer side of the zero-point positioning mounting plate 2, a sealing ring 5 is embedded inside the upper end of the sealing ring mounting plate 4, and a tray 6 is provided on the upper end of the sealing ring 5;

[0016] The outer wall of the zero point positioning mounting plate 2 is provided with connecting holes 7 all around, and the lower end of the sealing ring mounting plate 4 is provided with connecting grooves 8 all around. The sealing ring mounting plate 4 and the zero point positioning mounting plate 2 are connected to the connecting holes 7 by screws passing through the connecting grooves 8 for positioning.

[0017] Working principle: A sealing ring mounting plate 4 is sleeved on the outside of the zero point positioning mounting plate 2, and then a sealing ring 5 is placed in the sealing ring mounting plate 4, and then a pallet 6 is installed, so that the pallet 6 and the zero point positioning device 3 can be sealed under the action of the sealing ring 5. When the workpiece is processed, the impurities such as iron filings generated by the workpiece processing of the current pallet 6 can be blocked under the action of the sealing ring 5 and will not run into the zero point positioning device 3, so that when the next pallet 6 is put on the machine, the accuracy of its XYZ axis relative to the XYZ axis of the machine tool is guaranteed, thereby ensuring the yield rate of the product;

[0018] In addition, the new structure is simple, easy to maintain, and has good interchangeability. It only requires the sealing ring 5 to be clamped on the sealing ring mounting plate 4 without the need for mold opening. The sealing ring 5 is a consumable part, and the new structure uses universal accessories to reduce subsequent maintenance costs.
