Description
Technical field
The utility model relates to mechanical engineering technical field, particularly a kind of positioner.
Background technology
Along with the fast development of China's economic construction, market increases day by day for the demand of various types of positioner.
We know, in the production process of cam, need to hole to the end face of cam; And before drilling, cam should be positioned.
In the prior art, cam is vertically arranged in machining center by we, and the upper surface of cam is fixed, and the lower surface of cam is the end face needing boring, is so just fixed by the axial location of cam; In addition, also need to arrange positioner in the side of cam, in order to avoid in the process of boring, cause because cam is radially subjected to displacement the angle of holing to change excessive, thus produce waste product.
But positioner of the prior art is one piece of locating piece, the surface due to the cam contacted with locating piece is the surface irregularity of black skin, black skin; Therefore, cam cannot effectively position by locating piece, thus causes in boring procedure, and cam radially produces certain displacement, finally produces waste product.
Therefore, how solving percent defective height is the current technical issues that need to address of those skilled in the art.
Utility model content
The purpose of this utility model is to provide a kind of positioner, and this positioner can the radial position of effective stationary cam.
For achieving the above object, the utility model provides a kind of positioner, and described positioner comprises convex closure in order to stationary cam and along the V-shaped locating piece of the axis of described cam and fixing described locating piece, the positioning seat that arranges with the axis being parallel of described cam.
Preferably, described locating piece is vertical with described positioning seat is arranged.
Preferably, described locating piece and described positioning seat with bolts.
Preferably, the number of described bolt is five.
Preferably, the spring moved radially that described locating piece can be made along described cam is also provided with between described locating piece and described positioning seat.
Preferably, the number of described locating piece is three.
Relative to above-mentioned background technology, the positioner that the utility model provides, comprises convex closure in order to stationary cam and along the V-shaped locating piece of the axis of cam and stationary positioned block, the positioning seat that arranges with the axis being parallel of cam.Adopt this setup, effectively can utilize and be arranged on the locating piece on positioning seat the radial position of cam is fixed, and the locating piece of V-type can be fixed with the position of the convex closure of cam, the problem that location is inaccurate can not be caused due to the black skin at the convex closure place of cam; Thus ensure in boring procedure, the generation of waste product can not be caused due to the radial displacement of cam; So, rate of just can effectively reducing the number of rejects and seconds, improves the qualification rate of cam.

Fig. 2 is the schematic diagram of the plan structure in Fig. 1.
Detailed description of the invention
Core of the present utility model is to provide a kind of positioner, and this positioner can avoid the generation causing waste product due to the radial displacement of cam.
In order to make those skilled in the art understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1 and Fig. 2, the schematic diagram of the positive TV structure of the positioner that Fig. 1 provides for the utility model embodiment; Fig. 2 is the schematic diagram of the plan structure in Fig. 1.
Positioner provided by the utility model, comprises convex closure in order to stationary cam and along the V-shaped locating piece 1 of the axis of cam and stationary positioned block 1, the positioning seat 2 that arranges with the axis being parallel of cam.
Herein, the locating piece 1 of V-type is exactly the locating piece 1 with V-type groove.
The object of such setting is, the locating piece 1 be arranged on positioning seat 2 can be effectively utilized the radial position of cam to be fixed, and the locating piece 1 of V-type can contact with the convex closure of cam, the problem that location is inaccurate can not be caused due to the black skin at the convex closure place of cam; Thus ensure in boring procedure, the generation of waste product can not be caused due to the radial displacement of cam; So, rate of just can effectively reducing the number of rejects and seconds, improves the qualification rate of cam.
Certainly, we can arrange the locating piece 1 of the V-type of different size according to the size of the convex closure of cam, and V-type position is exactly in order to fit tightly with the convex closure of cam, thus ensure that the radial direction of cam is not subjected to displacement.
In addition, the material of locating piece 1 can be set to stainless steel or brass by us, and the locating piece 1 of other materials also can meet above-mentioned purpose certainly, repeats no more herein.
In addition, we can also arrange a groove in the centre at the V-type position of locating piece 1; That is, two sidewalls at V-type position are in order to the sidewall of the convex closure of cam of fitting, and the groove of the centre at V-type position leaves space in order to the top of the convex closure to cam, thus ensure that the convex closure of cam can all be contained in V-type groove.
In addition, we can be arranged vertical with positioning seat 2 for locating piece 1.
That is, because the axis being parallel of positioning seat 2 with cam is arranged, and locating piece 1 is perpendicular to positioning seat 2, and namely locating piece 1 and the axis of cam are mutually vertical; So, locating piece 1 just can fit tightly with the convex closure of cam.
In addition, we can by with bolts between locating piece 1 and positioning seat 2.
So, utilize bolt to be fixed on positioning seat 2 by locating piece 1, thus ensure can not produce displacement between locating piece 1 and positioning seat 2.Certainly, we can also utilize the mode of pin or welding locating piece 1 and positioning seat 2 to be fixed.
In addition, we can adopt five screws locating piece 1 and positioning seat 2 to be fixed; Certainly, according to actual conditions, we can also adopt four or six screws, repeat no more herein.
In addition, the spring 3 moved radially that locating piece 1 can be made along cam is also provided with between locating piece 1 and positioning seat 2.
That is, utilize spring 3 can adjust the horizontal level of locating piece 1, thus ensure to fit tightly with the convex closure of cam.
In addition, the number of locating piece 1 can also be set to three by us.
That is, if need machining cam axle, when the axial location of camshaft has three cams, three locating pieces 1 can be utilized to be fixed by the cam bag of three cams, thus realize the accuracy of boring.
Certainly, we according to actual conditions, can be arranged the locating piece 1 of different number, repeat no more herein.
Above positioner provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
