Abstract

The invention discloses a tool for drilling an excavator edge clamping bucket tooth base. The tool comprises a fixed base, a clamping fixture and a fastening device; a fixed groove is formed in the fixed base; the clamping fixture is provided with a through hole, and the aperture gradually shrinks from front to back; the inner profile of the through hole is matched with the outer profile of the clamped excavator edge clamping bucket tooth base; the clamping fixture is fixedly connected with the fixed base; the fastening device includes a screwing nut, an external thread drilling guide sleeve and a rotating handle; the screwing nut is fixedly connected to the upper end of the clamping fixture, and is near one side with a wider aperture; the inner wall of the external thread drilling guide sleeve is a smooth through hole, and the outer wall is a thread; the external thread drilling guide sleeve is in threaded connection with the screwing nut; and the rotating handle is fixedly connected to the upper end of the external thread drilling guide sleeve. The tool has the following beneficial effects: the device is simple in structure, is specially designed for drilling of the excavator edge clamping bucket tooth base, and is high in operation efficiency and stable in clamping.

Description

A kind of frock for the boring of excavator checkpost bucket tooth seat

Technical field

The invention belongs to frock clamp field, especially relate to a kind of frock clamp for the boring of excavator checkpost bucket tooth seat。

Background technology

Traditional excavator checkpost bucket tooth seat boring carries out on lathe, it does not have special frock clamp, clamps not tight, very easily causes coming off in processing boring procedure, not only make part cause damage, and easily cause the injures and deaths of processing staff。

Summary of the invention

For the deficiencies in the prior art, be inconvenient to, in order to solve bucket tooth seat boring in excavator checkpost in prior art, the problem clamped, the invention provides a kind of frock clamp for the boring of excavator checkpost bucket tooth seat。

A kind of frock for the boring of excavator checkpost bucket tooth seat, for clamping the frock of excavator checkpost bucket tooth seat, including firm banking, mold and clamp device, described firm banking has fixing groove, through hole is had in described mold, aperture gradually tapers up from front to back, the outline of the Internal periphery of through hole and held excavator checkpost bucket tooth seat matches, mold is fixing with firm banking to be connected, described clamp device includes tightening nut, external screw thread boring guide pin bushing and rotary handle, described tightening nut is fixedly connected on mold upper end, and close to aperture wider side, described external screw thread boring guide pin bushing, inwall is smooth bore, outer wall is screw thread, described external screw thread boring guide pin bushing with described tightening nut for threadeding, described rotary handle is fixedly connected on external screw thread drilling guide set upper side。

Preferably, described external screw thread drilling guide puts external screw thread is trapezoidal thread。

Preferably, described tightening nut female thread is trapezoidal thread。

Preferably, described external screw thread boring guide pin bushing inwall is embedded with wear ring。

Preferably, described external screw thread boring guide pin bushing external diameter is identical with hole, the location internal diameter of held excavator checkpost bucket tooth seat。

Technical scheme has the advantages that

The present invention provides a kind of frock clamp for the boring of excavator checkpost bucket tooth seat, this apparatus structure is simple, exclusively for excavator checkpost bucket tooth seat drilling design, use simple, hole, location is coordinated quickly to position high workload efficiency, simultaneously relatively prior art, clamp more firm, the possibility of minimizing production accident generation。

Accompanying drawing explanation

Below by drawings and Examples, technical scheme is described in further detail。

Fig. 1 is the front view of a kind of frock for the boring of excavator checkpost bucket tooth seat of the present invention；

Fig. 2 is A portion structure enlarged diagram in Fig. 1；

Detailed description of the invention

In order to have a clear understanding of technical scheme, its detailed structure be will be set forth in the description that follows。Obviously, the concrete also deficiency of implementing of the embodiment of the present invention is limited to the specific details that those skilled in the art has the knack of。The preferred embodiments of the present invention are described in detail as follows, except these embodiments of detailed description, it is also possible to have other embodiments。

Below in conjunction with drawings and Examples, the present invention is described in further details。

As shown in Figure 1, Figure 2, Figure 3 shows, the work process of this example: a kind of frock for the boring of excavator checkpost bucket tooth seat, including firm banking 1, mold 7 and clamp device 2,

Having fixing groove 8 on described firm banking 1, have through hole in described mold 7, aperture gradually tapers up from front to back, and the outline of the Internal periphery of through hole and held excavator checkpost bucket tooth seat matches,

Described mold 7 is fixing with firm banking 1 to be connected,

Described clamp device 2 includes tightening nut 6, external screw thread boring guide pin bushing 3 and rotary handle 5, described tightening nut 6 is fixedly connected on described mold 7 upper end, and close to aperture wider side, described external screw thread boring guide pin bushing 3, inwall is smooth bore, inwall lower end is embedded with wear ring 4, outer wall is trapezoidal thread, described external screw thread boring guide pin bushing 3 with described tightening nut 6 for threadeding, described rotary handle 5 is fixedly connected on external screw thread boring guide pin bushing 3 upper end, and described external screw thread boring guide pin bushing external diameter is identical with hole, the location internal diameter on held excavator checkpost bucket tooth seat。

First this frock is fixed on a stabilized platform by fixing groove 8, held excavator checkpost bucket tooth seat is put into mold 7 according to own profile feature internal, then passing through rotation rotary handle 5 drives external screw thread boring guide pin bushing 3 to rotate, under the effect of tightening nut 6, it is made to press down lower end to be simultaneously properly inserted in the hole, location of held excavator checkpost bucket tooth seat, now start punching, the wear ring 4 being built in external screw thread boring guide pin bushing 3 prevents drill bit from shaking, external screw thread of injuring boring guide pin bushing 3 inwall, rotary handle 5 is rotated backward after having punched, external screw thread boring guide pin bushing 3 lifts up, unclamp held excavator checkpost bucket tooth seat, then proceed to the excavator checkpost bucket tooth seat that processing is next held。

Finally should be noted that: above example is only in order to illustrate that technical scheme is not intended to limit; although the present invention being described in detail with reference to above-described embodiment; the specific embodiment of the present invention still can be modified or equivalent replacement by those of ordinary skill in the field; these are without departing from any amendment of spirit and scope of the invention or equivalent replace, all within the claims that application is awaited the reply。
