Description

Technical Field

[0001] This utility model relates to the field of fixture technology used in the passivation process of the cutting tool industry, and in particular to a drag-type passivation quick clamping fixture. Background Technology

[0002] With the development of the cutting tool industry, cutting tools need to be passivated after machining. Most passivation methods use a drag-type passivation method, which uses a three-jaw chuck type clamp. Each time the tool is loaded or unloaded, it needs to be turned by hand for a long time, which is time-consuming. Moreover, the internal condition of the clamp cannot be seen, which may lead to chipping of the cutting edge. After a period of use, if the clamp malfunctions, it cannot be repaired and can only be replaced with a new clamp, which wastes time and money. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a drag-and-drop passivation quick clamping fixture, which allows for rapid tool change and clamping positioning, saving time and costs. The viewing window facilitates observation of the cutting edge of the tool inserted into the fixture, preventing it from colliding with the inner wall of the fixture during installation and effectively protecting the cutting edge of the tool, thus bringing great convenience to production and use.

[0004] To solve the above-mentioned technical problems, the present invention adopts a drag-type passivation quick clamping fixture, comprising: a fixture body, a sleeve, a cutting tool, and an elbow clamp. The rear end of the cutting tool is disposed inside the sleeve, the sleeve is sleeved inside the fixture body, the sleeve is provided with a first clamping port, the fixture body is provided with a second clamping port, the elbow clamp is disposed on the fixture body, and has a clamping rod. When the cutting tool and the sleeve are inserted into the fixture body, the first clamping port and the second clamping port are aligned, and the lower end of the clamping rod extends into and passes through the first clamping port and the second clamping port to press and limit the cutting tool.

[0005] In a preferred embodiment of the present invention, a viewing window is provided on the clamp body behind the second clamping opening.

[0006] In a preferred embodiment of this utility model, the clamping rod is fixed to the elbow clamp by two sets of nuts, and the fixed height can be adjusted.

[0007] In a preferred embodiment of the present invention, the clamp body has four threaded holes, and the elbow clamp is installed in the corresponding threaded holes by four sets of fastening screws.

[0008] In a preferred embodiment of this utility model, the cutting tool and the sleeve are connected by a clearance fit, and the sleeve and the clamp body are connected by a clearance fit.

[0009] In a preferred embodiment of this utility model, the elbow clamp is a mechanical workpiece clamp.

[0010] The beneficial effects of this utility model are: the use of the elbow clamp allows for quick tool replacement and clamping positioning, saving time and cost; the viewing window allows for easy observation of the cutting edge of the tool inserted into the clamp body, preventing it from colliding with the inner wall of the clamp body during installation, thus avoiding chipping of the cutting edge and effectively protecting the cutting edge, saving installation time.

[0013] Figure 2 This is an exploded view of the drag-type passivation quick clamping fixture of this utility model. Detailed Implementation

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Please see Figure 1-2 This utility model discloses a drag-type passivation quick clamping fixture, comprising: a fixture body 1, a sleeve 2, a cutting tool 3, and an elbow clamp 4. The rear end of the cutting tool is inserted into the sleeve, and the two are tightly connected by a gap. The sleeve has a uniform outer diameter, but the inner diameter can be selected from different specifications of sleeves to adapt to different types of cutting tools. For cutting tools of different diameters, only the sleeve needs to be replaced. The sleeve is fitted into the fixture body, and the two are also tightly connected by a gap. A first clamping port 5 is provided on the sleeve, and a second clamping port 6 is provided on the fixture body. The elbow clamp is set on the fixture body and has a clamping rod 7. When the cutting tool and the sleeve are installed, the sleeve is inserted into the fixture body, so that the first clamping port and the second clamping port coincide. At this time, the elbow clamp is pressed down so that the lower end of the clamping rod at the front end of the elbow clamp extends into and passes through the first clamping port and the second clamping port to clamp and limit the cutting tool.

[0016] Specifically, in this embodiment, the elbow clamp is a mechanically fastened workpiece elbow clamp. The clamp body has four threaded holes 8. The elbow clamp is installed in the corresponding threaded holes by four sets of fastening screws 9. The clamping rod is fixed to the elbow clamp by two sets of nuts. The fixed height of the clamping rod can be adjusted by adjusting the fastening position of the nuts to accommodate different specifications of cutting tools. After the cutting tool, sleeve and clamp body are installed, the fixed height of the clamping rod is adjusted, and the elbow clamp is pressed down so that the lower end of the clamping rod abuts against the outer wall of the cutting tool. This allows for quick fixing and replacement of the cutting tool. More preferably, a rubber anti-slip pad can be connected to the lower end of the clamping rod to increase the friction with the outer wall of the cutting tool, making the fixation more stable and the clamping effect better.

[0017] Specifically, a viewing window 10 is provided on the fixture body behind the second clamping port. When the tool is inserted into the fixture body through the sleeve, the insertion depth of the tool rear end can be observed through the viewing window to prevent collision with the inner wall of the fixture body and avoid chipping of the tool edge. When changing tools of different diameters, only the sleeve with different inner diameter needs to be replaced, making disassembly and assembly quick and convenient.

[0018] The beneficial effects of this utility model are: the use of the elbow clamp allows for quick tool replacement and clamping positioning, saving time and cost; the viewing window allows for easy observation of the cutting edge of the tool inserted into the clamp body, preventing it from colliding with the inner wall of the clamp body during installation, thus avoiding chipping of the cutting edge and effectively protecting the cutting edge, saving installation time.

[0019] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
