Abstract
The utility model discloses a drilling jig for a track link of a coal digging machine. The drilling jig comprises an L-shaped base plate, wherein two rows of protrusions which are symmetrically distributed are arranged on the outer sides, vertical to a side plate, of the base plate, each protrusion is provided with a positioning drill hole, and the positioning drill holes of each row of the protrusions are on the same axis. According to the drilling jig for the track link of the coal digging machine, a track link to be machined is loaded in a workpiece, the two rows of the drill holes of the track link can be simultaneously machined after the workpiece is clamped, thus concentricity of the two rows of the drill holes of the track link can be guaranteed, and machining efficiency of the track link is improved. Therefore, the drilling jig has good application prospects.
Description
Technical field
The utility model relates to a kind of coal digging machine drilling clamp for grouser shoe, belongs to the mechanical part technical field of tooling clamps.
Background technology
The coal digging machine creeper tread is for supporting the transmission crawler belt on coal digging machine, creeper tread is arranged on the frame of tracked machine, in order to fixedly mount creeper tread, need to hole in the creeper tread both sides, traditional bore mode is by after measurement and positioning to the creeper tread both sides, boring one by one, before boring, need the manual measurement location, inefficiency, and due to manual measurement, the concentricity of creeper tread two row hole drillings is poor, affects the end product quality of creeper tread.
The utility model content
The purpose of this utility model overcomes deficiency of the prior art, the coal digging machine drilling clamp for grouser shoe provided, creeper tread to be processed is packed in frock, after clamping workpiece, can to two row hole drillings of creeper tread, process simultaneously, can guarantee the concentricity of creeper tread two row hole drillings, improve the working (machining) efficiency of creeper tread, have a good application prospect.
In order to achieve the above object, the technical scheme that the utility model adopts is:
The coal digging machine drilling clamp for grouser shoe is characterized in that: comprise the substrate of L shaped shape, the outside of described substrate perpendicular side plate is provided with the symmetrical projection of two rows, and each projection is provided with location drilling, and the location drilling on every row's projection is on same axis.
Aforesaid coal digging machine drilling clamp for grouser shoe is characterized in that: the protruding quantity of every row is six.
Aforesaid coal digging machine drilling clamp for grouser shoe is characterized in that: described location drilling is positioned at protruding center.
Aforesaid coal digging machine drilling clamp for grouser shoe is characterized in that: described two spacings of arranging between symmetrical projection are identical with the width of creeper tread.
The beneficial effects of the utility model are: coal digging machine drilling clamp for grouser shoe of the present utility model, creeper tread to be processed is packed in frock, after clamping workpiece, can to two row hole drillings of creeper tread, process simultaneously, can guarantee the concentricity of creeper tread two row hole drillings, improve the working (machining) efficiency of creeper tread, have a good application prospect.
The accompanying drawing explanation
Fig. 1 is the structural representation of coal digging machine drilling clamp for grouser shoe of the present utility model.
Fig. 2 is the structural representation of coal digging machine drilling clamp for grouser shoe of the present utility model.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figures 1 and 2, a kind of coal digging machine drilling clamp for grouser shoe, the substrate 1 that comprises L shaped shape, the outside of substrate 1 perpendicular side plate is provided with the symmetrical projection of two rows 2, the quantity of every row's projection 2 is six, identical with the row hole drilling quantity that will process creeper tread, two spacings of arranging between symmetrical projection 2 are identical with the width of creeper tread, the medial surface of projection 2 forms locating surface, can tighten creeper tread to be holed, each projection 2 is provided with location drilling 3, location drilling 3 on every row's projection 2 is on same axis, can guarantee the concentricity of creeper tread two row hole drillings, conveniently two row hole drillings of creeper tread are processed simultaneously, improve the working (machining) efficiency of creeper tread, location drilling 3 is positioned at the center of projection 2, can increase the intensity of projection 2, while guaranteeing projection 2 long-term use, do not crack.
In sum, coal digging machine drilling clamp for grouser shoe of the present utility model, creeper tread to be processed is packed in frock, after clamping workpiece, can to two row hole drillings of creeper tread, process simultaneously, can guarantee the concentricity of creeper tread two row hole drillings, improve the working (machining) efficiency of creeper tread, have a good application prospect.
Above demonstration and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
