Abstract
The utility model discloses a portable hole cutting equipment, including the connecting rod, be connected with the fixing base through the bearing on this connecting rod, this fixing base is the cylinder structure the position that is close to its first half section on the connecting rod is provided with the external screw thread section, and the spiro union has circular cutter on this external screw thread section be provided with the blanking breach on the fixing base, this blanking breach with the centre bore intercommunication of fixing base. The utility model discloses a device overall structure is simple, and the volume is less, convenient to use, low in manufacturing cost especially is suitable for the eager hole process of the limited product in space (the unsuitable product that adopts the cutting of large-scale full-automatic eager hole equipment), conveniently carries, and follow-up maintenance is simple, convenient.
Description
Technical Field
The utility model relates to a drilling equipment technical field, concretely relates to portable hole cutting equipment.
Background
Need carry out the cut hole operation to it in the product (like car bumper) manufacturing process, adopt punching equipment at present when carrying out the cut hole operation to it, this punching equipment can once only accomplish the die-cut of all holes on the product, but this equipment is bulky, and occupation space is great during the use, is not suitable for to the limited place in space, simultaneously, because the great overall structure that causes of volume is complicated, the operation is inconvenient, and the cost is higher, and follow-up maintenance is inconvenient.
Disclosure of Invention
To the technical problem that exists at present, the utility model provides a portable hole cutting equipment to solve among the prior art because the various problems that the structural constraint leads to.
In order to achieve the purpose of the invention, the utility model provides the following technical scheme:
the utility model provides a portable hole cutting equipment, includes the connecting rod, is connected with the fixing base through the bearing on this connecting rod, and this fixing base is the cylinder structure the position that is close to its first half section on the connecting rod is provided with the external screw thread section, and the spiro union has circular cutter on this external screw thread section be provided with the blanking breach on the fixing base, this blanking breach with the centre bore intercommunication of fixing base.
Preferably, the fixing seat is provided with a screw fixing hole along a radial direction thereof, a screw is installed in the screw fixing hole during assembly, and a lower end of the screw abuts against an outer periphery of the bearing.
So set up, the accessible screw is fixed bearing and fixing base, has avoided in the use because the connecting rod rotates and produces the fixing base and connect and influence performance.
Preferably, a clamping groove is further formed in the connecting rod, a clamping spring is mounted in the clamping groove, and the clamping spring abuts against the outer end face of the bearing.
So set up, carry out axial spacing fixed with the jump ring to the bearing, avoided axial displacement to appear in the use bearing.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a device overall structure is simple, and the volume is less, convenient to use, low in manufacturing cost especially is suitable for the eager hole process of the limited product in space (the unsuitable product that adopts the cutting of large-scale full-automatic eager hole equipment), conveniently carries, and follow-up maintenance is simple, convenient.
Description of the drawings:
fig. 1 is a schematic diagram of the explosion structure of the present invention;
fig. 2 is a schematic structural diagram of the present invention in a use state.
Detailed Description
The present invention will be described in further detail with reference to test examples and specific embodiments. However, it should not be understood that the scope of the above-mentioned subject matter is limited to the following embodiments, and all the technologies realized based on the present invention are within the scope of the present invention.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships illustrated in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
In the description of the present invention, unless otherwise specified and limited, it is to be noted that the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, mechanically or electrically connected, or may be connected between two elements through an intermediate medium, or may be directly connected or indirectly connected, and specific meanings of the terms may be understood by those skilled in the art according to specific situations.
The portable hole cutting equipment shown in the attached drawing 1 comprises a connecting rod 1, wherein a fixed seat 2 is connected to the connecting rod 1 through a bearing 3, the fixed seat 2 is of a cylindrical structure, an external thread section 11 is arranged on the connecting rod 1 close to the first half section of the connecting rod, a circular cutter 4 is screwed on the external thread section 11, a blanking notch 21 is arranged on the fixed seat 2, and the blanking notch 21 is communicated with a central hole of the fixed seat 2. The fixing seat 2 is provided with a screw fixing hole 20 along the radial direction, a screw is arranged in the screw fixing hole 20 during assembly, and the lower end of the screw abuts against the periphery of the bearing 3.
In order to avoid axial movement of the bearing 3 during use, a clamping groove 12 is further arranged on the connecting rod 1, a clamping spring 5 is installed in the clamping groove 12, and the clamping spring 5 abuts against the outer end face of the bearing 3.
Fig. 2 is the utility model discloses state when using, during the use, connect the one end that connecting rod 1 did not establish the screw thread on the electric drill, jump ring 5 supports on the outer terminal surface of bearing 3, the screw is installed in screw fixation hole 20, and the lower extreme supports in the bearing 3 periphery, it is downthehole that the reservation aperture of injection moulding product is stretched into to be equipped with threaded one end on connecting rod 1, then electric drill 6 is rotatory to drive connecting rod 1, circular cutter 4 radially draws in the hole operation of cutting, the piece that the cutting produced falls from blanking breach 21.
The foregoing describes preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
