Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of camshaft detection, in particular to a placement table for manual detection of a camshaft. Background Art
[0002] The traditional camshaft journal runout detection tool requires manual tightening of the locking center to detect the runout of a single journal. If it is necessary to detect the runout of other adjacent journals, it is necessary to manually push the detection dial indicator to the position of the journal to be tested, and then adjust the dial indicator reading before testing it. Generally, there are multiple journals on a camshaft. The detection operation steps of this method are cumbersome, and the accumulated detection errors have a great impact on the measurement results. The time-consuming and labor-intensive detection method can no longer meet the requirements of current batch product testing. Utility Model Content
[0003] The utility model aims to solve the problem of complicated detection process in the prior art and proposes a placement table for manual detection of a camshaft.
[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0005] A placement table for manual camshaft inspection includes a test table and two support members arranged on the surface of the test table, both of which have V-shaped grooves on their surfaces, one of which slides on the surface of the test table through two slide grooves, an offset component provided on the surface of the test table, a plurality of mounting brackets for mounting a detector slidingly provided on the surface of the offset component, and a positioning component provided inside the test table for positioning the offset component;
[0006] The offset assembly includes a slide rail slidably arranged on the upper surface of the detection platform and a plurality of fixed platforms slidably connected to the surface of the slide rail.
[0007] In some embodiments, the positioning assembly includes a stopper fixed on the lower surface of the slide rail and a movable block for limiting the sliding position of the stopper toward the camshaft. A threaded column is rotatably connected to the inside of the detection platform through a bearing, and the movable block is threadedly connected to the surface of the threaded column.
[0008] In some embodiments, the upper surfaces of the plurality of fixing platforms are respectively provided with positioning rods for positioning the magnetic seat at the bottom of the mounting frame.
[0009] In some embodiments, the sliding support member is fixed to the surface of the detection table by a first limiting assembly, and the first limiting assembly includes a vertically sliding insertion rod and a plurality of insertion holes opened on the surface of the detection table, and the insertion rod cooperates with the insertion holes.
[0010] In some embodiments, the plurality of mounting brackets are fixed to the surface of the slide rail via a second limiting assembly, wherein the second limiting assembly includes a limiting rod rotatably disposed on the surface of the fixed platform and a plurality of limiting slots provided on the surface of the slide rail.
[0011] In some embodiments, the offset assembly further includes two first guide rods symmetrically fixed inside the detection platform and two sliders sliding on the surfaces of the two first guide rods, and both of the sliders are fixedly connected to the lower surface of the slide rail.
[0012] Compared with the prior art, the present invention provides a placement table for manual inspection of camshafts, which has the following beneficial effects.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0024] Reference Figure 1-5 The camshaft manual inspection placement table includes a detection table 1 and two support members 2 arranged on the upper surface of the detection table 1. The detection table 1 is bow-shaped, and the bottom of the detection table 1 is fixed by multiple bolts. The surfaces of the two support members 2 are both provided with V-shaped grooves. Two slide grooves 3 are provided on the upper surface of the detection table 1. The two slide grooves 3 are dovetail grooves. One of the support members 2 slides on the upper surface of the detection table 1 through the two slide grooves 3.
[0025] It can be understood that by providing a V-shaped groove on the surface of the support member 2, it is convenient to use with camshafts of different diameters. By sliding one of the support members 2 on the surface of the detection table 1, the distance between the two support members 2 can be adjusted, which facilitates the support of camshafts of different lengths.
[0026] Specifically, an offset component 4 is provided on the surface of the testing platform 1, and the offset component 4 includes a slide rail 401 slidably set on the upper surface of the testing platform 1 and a plurality of fixed platforms 402 slidably connected to the surface of the slide rail 401, and the fixed platform 402 is extended close to one side of the support member 2. Two first guide rods 403 and two sliders 404 sliding on the surfaces of the two first guide rods 403 are symmetrically fixed inside the testing platform 1. A plurality of through grooves are opened on the surface of the testing platform 1, and the upper surfaces of the two sliders 404 are fixedly connected to the lower surface of the slide rail 401 through the through grooves. The two sliders 404 both slide on the inner wall of the slide groove 3, and both ends of the slide rail 401 are open.
[0027] It can be understood that by setting the offset component 4, the slide rail 401 slides on the surface of the first guide rod 403 through the slider 404, thereby driving multiple fixed platforms 402 to slide on the surface of the detection platform 1, so as to facilitate the synchronous driving of multiple detectors to approach or move away from the camshaft, so that when the camshaft is taken, the detector is kept away from the camshaft to avoid the camshaft colliding with the detector during the taking process, thereby causing its accuracy to be damaged. By having multiple detectors approach the camshaft synchronously, it is convenient to quickly start detecting the camshaft. By setting the two ends of the slide rail 401 to be open, it is convenient to increase or decrease the number of fixed platforms 402 so that it corresponds to the number of camshaft shaft diameters.
[0028] Specifically, a mounting bracket 6 for mounting the detector is provided on the upper surface of the fixed platform 402. The mounting bracket 6 includes a magnetic seat and a vertical rod for adjusting the height of the detector. The vertical rod is fixed on the upper surface of the magnetic seat. A connecting bracket is slidably connected to the surface of the vertical rod. The detector is fixedly assembled on the surface of the connecting bracket. The connecting bracket is limited to the surface of the vertical rod by threads. Positioning rods 9 for positioning the magnetic seat are respectively provided on the upper surfaces of multiple fixed platforms 402.
[0029] By setting up multiple mounting brackets 6, it is convenient to detect multiple shaft diameters on the camshaft surface at the same time. The detector is magnetically attached to the surface of the fixed platform 402 through a magnetic seat. By setting up a positioning rod 9, it is convenient to position the angle of the magnetic seat so that the detector and the camshaft maintain a vertical angle to avoid affecting the detection accuracy. The height of the detector is adjusted to the same height as the camshaft axis by sliding the connecting bracket vertically on the surface of the vertical rod.
[0030] Specifically, the detection platform 1 is internally provided with a positioning assembly 5 for positioning the offset assembly 4. The positioning assembly 5 includes a stopper 503 fixed to the lower surface of the slide rail 401 and a movable block 502 for limiting the position of the stopper 503. A threaded column 501 is rotatably connected to the detection platform 1 through a bearing. The movable block 502 is threadedly connected to the surface of the threaded column 501. The movable block 502 slides on the inner wall of the through groove. A handwheel is fixedly connected to one end of the threaded column 501.
[0031] It can be understood that by rotating the handwheel, the threaded column 501 is driven to rotate, thereby driving the moving block 502 to move. Under the action of the moving block 502 and the stop block 503, the position of the slide rail 401 sliding toward the camshaft is limited, making it convenient to quickly and accurately push multiple detectors to the camshaft surface.
[0032] Specifically, the sliding support member 2 is fixed to the surface of the detection platform 1 through the first limiting component 7. The first limiting component 7 includes two second guide rods 701 vertically fixed inside the support member 2. The surfaces of the two second guide rods 701 are slidably connected with a slide 702. The outer side of the slide 702 extends out of the range of the support member 2. The surfaces of the two second guide rods 701 are sleeved with a first spring 703. The first spring 703 is a tension spring. The lower surface of the slide 702 is fixedly connected with an insertion rod 704. A plurality of sockets 705 are provided on the upper surface of the detection platform 1. The plurality of sockets 705 are arranged in an array between the two slide grooves 3, and the insertion rod 704 cooperates with the socket 705.
[0033] It can be understood that the first spring 703 pulls the slide plate 702 and the insertion rod 704 to slide downward, so that the insertion rod 704 is inserted into the socket 705, thereby limiting the position of the support member 2. By pulling the slide plate 702 upward, the insertion rod 704 is driven out of the socket 705, thereby facilitating the release of the limit on the support member 2 and allowing the support member 2 to slide on the surface of the detection table 1.
[0034] Specifically, multiple mounting brackets 6 are fixed to the surface of the slide rail 401 through a second limiting assembly 8. The second limiting assembly 8 includes a connecting shaft 801 fixed to the surface of the fixed platform 402. The surface of the connecting shaft 801 is rotated with a limiting rod 802. The surface of the slide rail 401 is provided with multiple limiting grooves 804. The lower end of the limiting rod 802 is bent toward the limiting groove 804. The surface of the connecting shaft 801 is provided with a torsion spring 803 that drives the lower end of the limiting rod 802 to rotate toward the limiting groove 804. The limiting groove 804 cooperates with the limiting rod 802.
[0035] It is understandable that by providing the limiting rod 802 , the torsion spring 803 drives the limiting rod 802 to rotate, so that the lower end of the limiting rod 802 is clamped in the limiting groove 804 , thereby limiting the position of the fixing platform 402 .
[0036] In the present invention, by pulling the slide plate 702 upward, the insertion rod 704 is driven to disengage from the insertion hole 705, thereby releasing the limit of the support member 2, allowing the support member 2 to slide on the surface of the detection platform 1, and adjusting the distance between the two support members 2 so that it can support both ends of the camshaft to be detected. Under the action of the first spring 703, the slide plate 702 and the insertion rod 704 are pulled downward to insert the insertion rod 704 into the insertion hole 705, limiting the position of the support member 2, and placing the camshaft to be detected in the V-shaped groove. According to the number of shaft diameters on the surface of the camshaft, the number of fixed platforms 402 on the surface of the slide rail 401 is adjusted to be the same as the number of shaft diameters. Then, under the action of the positioning rod 9, the mounting bracket 6 is fixed to the surface of the fixed platform 402 according to the magnetic seat, and the upper end of the limiting rod 802 is pressed to rotate the limiting rod 802. , disengage from the limit groove 804, slide the position of the fixed platform 402 and the mounting bracket 6 to the shaft diameter position, and drive the limit rod 802 to be clamped in the limit groove 804 through the torsion spring 803 to limit the position of the fixed platform 402, and adjust the position of the mounting bracket 6 so that the detector contacts the shaft diameter, and then, turn the handwheel to drive the threaded column 501 to rotate, so that the moving block 502 contacts the stop block 503, and then manually rotate the camshaft to detect the shaft diameter. After the detection is completed, pull the slide rail 401 to slide in the direction of the handwheel to disengage multiple detectors from the camshaft surface, remove the camshaft and replace it with the next camshaft of the same specification, place it in the V-shaped groove, and then push the slide rail 401 to drive multiple detectors to contact the camshaft at the same time, which is convenient for rapid detection and improves detection efficiency.
