Abstract
The utility model discloses a self-centering quick-clamping drill jig, which comprises a drill jig body, wherein an inner hole is formed in the center of the drill jig body; three clamping devices are uniformly along the radial direction of the drill jig body; one end of each clamping device is communicated with a cylinder sleeve inner hole while the other end is communicated with the outer wall of the drill jig body; a drilling sleeve is arranged on a shoulder surface of the drill jig body. When the drill jig is placed in the cylinder sleeve inner hole of a to-be-machined part, the three clamping devices distributed on the drill jig body uniformly are enabled to move in a radial direction, so as to further stretch out of the outer wall of the drill jig body to be in contact with the cylinder sleeve inner hole of the to-be-machined part, so that rapid centering and clamping is realized. Therefore, after the part is machined by the drilling sleeve arranged on the shoulder surface of the drill jig body, machined screw holes are distributed uniformly, and uniform screw hole reference circles and good degree of circle center of the cylinder sleeve inner hole are achieved.
Description
Technical field
The utility model belongs to field of machining, is specifically related to a kind of self-centering and clamps drill jig fast.
Background technology
In mechanical industry production reality, there are a large amount of cylinder sleeve class parts to need processing, its end face edge all is furnished with the screw that quantity does not wait, and cylinder sleeve bores and attacks screw through turning, finish grindes inside and outside circle and end face at last and forms.When processing parts end face screw, because the grinding allowance difference that rough turn endoporus stays brings difficulty for the processing of the uniform screw of part end face, fixedly drill jig can not use, and line can not guarantee the uniform of hole, does not reach designing requirement, and working (machining) efficiency is extremely low.
Summary of the invention
At above-mentioned defective or deficiency, it is a kind of simple in structure that the utility model provides, and the self-centering of high efficiency clamps drill jig fast.
The purpose of this utility model solves by the following technical programs:
Comprise model drilling body, the center of model drilling body offers endoporus, along model drilling body radially, evenly be provided with three clamping devices, and an end of clamping device is connected with cylinder sleeve bore, and the other end is communicated with the outer wall of model drilling body, and the shoulder face of described model drilling body is provided with drill bushing.
Described clamping device comprises: be fixed in the swivel nut on the model drilling body, spring is installed on the swivel nut, be arranged with fulcrum post in the spring, and an end of fulcrum post is connected with cylinder sleeve bore, the other end is communicated with the outer wall of model drilling body.
The end of described fulcrum post is ramp structure, and is placed with steel ball on the end chamfer of three fulcrum posts.
Described self-centering clamps drill jig fast and also comprises the screw handle that matches with cylinder sleeve bore.
The utility model provides a kind of self-centering to clamp drill jig fast, offer endoporus by the center in model drilling body, and along model drilling body radially, evenly be provided with three clamping devices, wherein, one end of clamping device is connected with cylinder sleeve bore, the other end is communicated with the outer wall of model drilling body, when drill jig is positioned in the cylinder sleeve bore of required processing parts, force that the trisection clamping device moves radially on the model drilling body, and then clamping device stretches out the outer wall of model drilling body, contact with the cylinder sleeve bore wall of required processing parts, realized that quick centering clamps, therefore, after by the drill bushing that arranges on the model drilling body shoulder face part being added, the screw five equilibrium that processes is even, evenly screw reference circle and cylinder sleeve bore center of circle degree are good, in addition, because model drilling body of the present invention making is simple, and processing parts precision height, the efficient height, therefore, be suitable for the processing of part in batches.
Description of drawings
Fig. 1 is the structural representation that self-centering of the present utility model clamps drill jig fast.
Among the figure, 1 is the screw handle, and 2 is drill bushing, and 3 is swivel nut, and 4 is fulcrum post, and 5 is model drilling body, and 6 is spring.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
With reference to shown in Figure 1, the utility model provides a kind of self-centering to clamp drill jig fast, comprises model drilling body 5, and the center of model drilling body 5 offers endoporus, is provided with the screw handle 1 that matches with it in the endoporus; Along model drilling body 5 radially, evenly be provided with three clamping devices, and an end of clamping device is connected with cylinder sleeve bore, the other end is communicated with the outer wall of model drilling body 5, and the shoulder face of described model drilling body 5 is provided with drill bushing 2.Concrete, clamping device comprises: be fixed in the swivel nut 3 on the model drilling body 5, spring 6 is installed on the swivel nut, be arranged with fulcrum post 4 in the spring 6, and an end of fulcrum post 4 is connected with cylinder sleeve bore, the other end is communicated with the outer wall of model drilling body 5, and the end of described fulcrum post 4 is ramp structure, is placed with steel ball on the end chamfer of three fulcrum posts 4.
The utility model course of work:
For guaranteeing the machining accuracy of the uniform screw of part, the utility model utilization centering clamps principle, and the external diameter of drill jig is consistent with the cylinder sleeve bore diameter of required processing parts, is D, therefore, can stay maximum surplus processing by cylinder sleeve bore.During work, earlier drill jig is put into the cylinder sleeve bore of required processing parts; Then, by model drilling body 5 shoulder faces that model drilling body 5 is fixing, secondly, screw screw handle 1, depress steel ball, force on the model drilling body 5 trisection fulcrum post 4 radially mobile outside the outer wall of model drilling body 5, and then fulcrum post 4 stretches out the outer wall of model drilling body 5, closely contact with the cylinder sleeve bore wall of required processing parts, realize that centering clamps fast; After processing unthreaded hole, against revolving screw handle 1, fulcrum post 4 is return under the pressure effect of spring 6, can take out drill jig, then required processing parts is carried out tapping.
Drill jig in the utility model uses by actual, effective, can realize cylinder sleeve bore location and the centering clamping fast of size dispersion 0-1mm, it is even to process the screw five equilibrium, evenly screw reference circle and cylinder sleeve bore center of circle degree are good, and in addition, the utility model is made simple, processing parts precision height, efficient height are suitable for part processing in batches.
