Description
Technical Field
The invention relates to a camshaft end face verticality detection clamp.
Background
At present, various methods are available for detecting the perpendicularity of the end face of the camshaft, if three coordinates are used for detecting the perpendicularity of the end face of the camshaft, as professionals are required to perform three-coordinate detection operation, common camshaft processing enterprises are difficult to meet the requirements of three-coordinate special equipment and professionals on the three-coordinate detection operation, so that the three-coordinate detection is adopted, the detection period is long, the investment cost is high, the consumed time is long, the end face of the camshaft is provided with holes or grooves, the holes or the grooves cannot be contacted during detection, the detection contact surface is small, the detection precision is poor, and the error is large; the camshaft projector is used for detection, and the detection period is relatively long due to the fact that operation of professionals is needed, the detection requirement of the end face is relatively high, and the detection requirement of the equipment cannot be met in the aspects of detection precision and errors.
Disclosure of Invention
The invention aims to provide a camshaft end face verticality detection clamp, which overcomes the defects of the existing detection means, has the effects of short detection period and accurate and reliable detection result, greatly improves the detection accuracy and the production efficiency, reduces the process cost, and eliminates the phenomena of high specialization degree and easiness in false detection in the original detection process.
In order to achieve the purpose, the camshaft end face verticality detection clamp comprises a clamp body and a detection mechanism, wherein the clamp body comprises a bottom plate, a head fixing sleeve, a fixing tip, a tail fixing sleeve and a moving tip, the head fixing sleeve and the tail fixing sleeve are respectively connected with two ends of the bottom plate, the fixing tip is arranged in the middle of the head fixing sleeve, the moving tip is arranged in the middle of the tail fixing sleeve, the tail end of the moving tip is movably connected with a handle, the detection mechanism comprises a guide rod, a gauge seat frame and a dial gauge, the guide rod is arranged at the front end of the bottom plate, the gauge seat frame is arranged on the guide rod and can slide along the guide rod, and the dial gauge is movably connected to the front end of the gauge seat frame.
The middle part of the head fixing sleeve is provided with a through hole, and the fixing center is arranged in the through hole and fixedly connected.
The tail end of the fixed centre is fixed in the middle of the head fixed sleeve by welding.
The middle part of the tail fixing sleeve is provided with a through hole, and the movable center is arranged in the through hole and movably connected.
The telescopic moving distance of the movable center is 1-10 cm.
Compared with the prior art, the camshaft end face verticality detection clamp has the following excellent effects.
The cam shaft end face verticality detection clamp adopts an integrated assembly structure, when cam shafts with different lengths and specifications are clamped, the cam shafts can be smoothly installed on the clamp body only by adjusting the movable center, the detection mechanism is combined, the detection operation is flexible, the detection and use are convenient, the smooth detection is guaranteed, the detection result is accurate and reliable, the adjustment is easy in the detection process, the compatibility of a detection product is good, the detection product is easy to master by common workers, the product is fast to change the model, the detection period is short, the size of the detection tool is small, the detection tool is suitable for the production detection of mass products, large-scale detection equipment such as large-scale three-coordinate projectors is not required to be purchased, and the production cost is reduced.

Wherein: 1. the instrument comprises a bottom plate, a meter seat frame, a head fixing sleeve, a fixing tip, a guide rod, a dial indicator, a movable tip, a tail fixing sleeve and a handle, wherein the bottom plate is 2, the meter seat frame is 3, the head fixing sleeve is 4, the fixing tip is 5, the guide rod is 6, the dial indicator is 7, the tail fixing sleeve is 8, and the handle is 9.
Detailed Description
The perpendicularity detection clamp for the end face of the camshaft is further described in detail with reference to the accompanying drawings.
The camshaft terminal surface straightness that hangs down that figure 1 shows detects anchor clamps, constitute by anchor clamps body and detection mechanism, the anchor clamps body is by bottom plate 1, the fixed cover 3 of head, fixed top 4, the fixed cover 8 of afterbody, it constitutes to remove top 7, the fixed cover 3 of head and the fixed cover 8 of afterbody are connected with bottom plate 1's both ends respectively, fixed top 4 sets up at the fixed cover 3 middle part of head, it sets up the middle part at the fixed cover 8 of afterbody to remove top 7, remove top 7's tail end swing joint handle 9, detection mechanism is by guide arm 5, gauge stand 2, amesdial 6 constitutes, guide arm 5 sets up at bottom plate 1 front end, set up gauge stand 2 on the guide arm 5, gauge stand 2 can slide along guide arm 5, amesdial 6 swing joint is at gauge stand 2 front ends.
The middle part of the head fixing sleeve 3 is provided with a through hole, and the fixing center 4 is arranged in the through hole and fixedly connected.
The tail end of the fixed centre 4 is fixed in the middle of the head fixed sleeve 3 by welding.
The middle part of the tail fixing sleeve 8 is provided with a through hole, and the movable centre 7 is arranged in the through hole and movably connected.
The telescopic moving distance of the movable center 7 is 1-10 cm.
When the camshafts with different length specifications are clamped, only the movable center 7 needs to be adjusted, the camshafts can be smoothly installed on the fixture body, the detection surface of each camshaft faces the guide rod 5, the front end center hole of each camshaft is tightly contacted with the fixed center 4, the movable center 7 is loosened by the rotating handle 9, the movable center 7 can go deep into the tail end center hole of each camshaft, the movable center 7 tightly pushes the camshafts by rotating the handle 9 again, the position of the dial gauge seat frame 2 is adjusted, the measuring head of the dial gauge 6 is contacted with the detection surface of each camshaft, the dial gauge seat frame 2 moves along the guide rod 5, the camshafts are rotated simultaneously, the measuring head of the dial gauge 6 is not contacted with holes or grooves in the end surface of each camshaft, and the maximum value minus the minimum value of the reading value of the dial gauge 6 is the detection value of the end surface verticality.
