Background technology:
In machining, by the axle after Cutter Body Processing with Machining Center, in order to reach the technical parameter requirement of customer demand, all need after processing to detect by pick-up unit, general mode of operation is to carry out section by the skilled labor by vernier caliper to measure, and whether meets standard through right alignment and the surperficial linearity that self experience obtains out this axle.Such mode of operation at the processing plain shaft, is feasible when not high to the accuracy requirement of axle, but very high for the axle requirement of making cutter, this mode of operation is infeasible, and it is very large that the conclusion that draws and actual error differ.
Summary of the invention:
The technical matters that the utility model solves is to provide a kind of axle to the making cutter and carries out the detection of right alignment and surperficial linearity, and measurement data is accurate, and the high a kind of pick-up unit for detection of axle right alignment and surperficial linearity of detection efficiency.
The technical scheme in the invention for solving the technical problem is: a kind of pick-up unit for detection of axle right alignment and surperficial linearity comprises altimeter and the clamping device that is arranged on altimeter one side; This clamping device comprises base, be arranged with two rotating shafts in parallel on described base, head in a rotating shaft is socketed with runner, the opposite side of this rotating shaft is connected with rocking bar, is socketed with driven runner at the head of another rotating shaft, is connected with the first runner by curved bar above described runner and driven runner, the below, middle part of this curved bar is connected with spring, the other end of described spring is fixed on base, other end socket one bearing pin of curved bar, and the other end of this bearing pin connects one handle.
Further, for the axle that is placed in runner, driven runner and the first runner is effectively gripped, described runner equates with the diameter of driven runner, the diameter of described the first runner is less than the diameter of runner and driven runner, and the thickness of this runner, driven runner and the first runner is greater than 1/3rd length of the axle of needs detection.
Further, in order to guarantee that runner and driven runner stretch out front end and flush, when guaranteeing that the axle that need to detect is placed between runner, driven runner and the first runner, can be all circumscribed with the circle at its place, serial connection one locating shaft on described base, at the head of this locating shaft by the fixedly sleeved fastener of nut.
Further, in order to extend its serviceable life, the wearing and tearing between the axle that reduction runner, driven runner and the first runner and needs detect all are equipped with foam-rubber cushion in the bottom of described runner, driven runner and the first runner.
The beneficial effect of this device: this device is placed between the first runner, runner and driven runner by the axle that will need to detect and is fixed, afterwards the probe on altimeter is placed on the surface of axle, rotate by rocking bar afterwards, demonstrate it by altimeter high scale table and measure numerical value, final right alignment and the surperficial linearity that gets shaft.
Description of drawings:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of clamping device;
Fig. 3 is the schematic diagram of another angle of clamping device.
In figure: 1, altimeter 11, elevating lever 12, graduation apparatus 13, probe 2, clamping device 3, driven runner 4, the first runner 41, curved bar 42, handle 43, spring 5, runner 51, rocking bar 6, fastener 7, base.
Embodiment:
A kind of pick-up unit for detection of axle right alignment and surperficial linearity as shown in Figure 1, the clamping device 2 that comprises altimeter 1 and be arranged on altimeter one side, described altimeter 1 comprises the probe 13 that contacts with axle when detecting, draws the graduation apparatus 12 of right alignment and surperficial linearity by the demonstration data, and the elevating lever 11 that can play the whole altimeter of lifting; This clamping device 2 comprises base 7, be arranged with two rotating shafts in parallel on described base, head in a rotating shaft is socketed with runner 5, the opposite side of this rotating shaft is connected with rocking bar 51, head in another rotating shaft is socketed with driven runner 3, be connected with the first runner 4 by curved bar 41 above described runner 5 and driven runner 3, the below, middle part of this curved bar 41 is connected with spring 43, the other end of described spring 43 is fixed on base, other end socket one bearing pin of curved bar 41, the other end of this bearing pin connects one handle 42.
Further, for the axle that is placed in runner 5, driven runner 3 and the first runner 4 is effectively gripped, described runner 5 equates with the diameter of driven runner 3, the diameter of described the first runner 4 is less than the diameter of runner 5 and driven runner 3, and the thickness of this runner 5, driven runner 3 and the first runner 4 is greater than 1/3rd length of the axle of needs detection.
Further, as shown in Fig. 2 and 3, in order to guarantee that runner 5 and driven runner 3 stretch out front end and flush, when guaranteeing that the axle that need to detect is placed between runner 5, driven runner 3 and the first runner 4, can be all circumscribed with the circle at its place, serial connection one locating shaft on described base 7, at the head of this locating shaft by the fixedly sleeved fastener 6 of nut, also offer chute on described fastener 6, the fixed position of this fastener 6 can be regulated.
Further, in order to extend its serviceable life, wearing and tearing between the axle that reduces runner 5, driven runner 3 and the first runner 4 and need to detect, bottom at described runner 5, driven runner 3 and the first runner 4 all is equipped with foam-rubber cushion, and this foam-rubber cushion also can detect needs axle surface is cleared up.
choose the axle that needs detection, hand presses handle 42 downwards, the first runner 4 that handle drives curved bar 41 heads lifts, axle is placed on runner 5 and driven runner 3, the hand release handle 42 afterwards, the first runner is pressed together on axle, then by elevating lever 11 timely adjustment height, probe 13 is taken the upper surface that is placed on axle, then, the hand bar 51 that shakes, then runner 5 rotates, thereby drive driven runner 3 and the first runner 4 rotations, also having driven axle rotates, after rotating a week, draw a series of data on graduation apparatus 12, if data are unchanged, draw right alignment and surperficial linearity is better, amplitude of variation is larger if the data on graduation apparatus 12 are beated, and the technical parameter of the right alignment of this axle and surperficial linearity is relatively poor, does not meet standard.
This device is placed between the first runner, runner and driven runner by the axle that will need to detect and is fixed, afterwards the probe on altimeter is placed on the surface of axle, rotate by rocking bar afterwards, demonstrate it by altimeter high scale table and measure numerical value, final right alignment and the surperficial linearity that gets shaft.
