Examples
The following is further described with reference to specific embodiments, as shown in fig. 1-4, the device for on-line checking of a crankshaft 30 for a general grinder in this embodiment includes a support rod 10 horizontally and fixedly arranged above the grinder, a sleeve 11 slidably sleeved on the support rod 10, a connecting plate 14 fixedly connected to an outer side wall of the sleeve 11, a connecting rod 15 hinged to one surface of the connecting plate 14, and a dial indicator 20 connected to the connecting rod 15; the dial gauge 20 is an inside diameter dial gauge 20. Specifically, the supporting rod 10 in the device can be directly installed on an old grinder, then the sleeve 11 is moved to a proper position and then fixed (the measuring pointer on the dial indicator 20 can be horizontally clamped), in the process of machining the crankshaft 30, when the gear of the crankshaft 30 is required to be checked (the measuring size is pointed out), the dial indicator 20 can be directly held, then the connecting rod 15 is rotated, then the sleeve 11 is rotated, the probe 22 of the final dial indicator 20 is clamped in the gear of the crankshaft 30, the gear of the crankshaft 30 can be detected in real time, after the detection is completed, the dial indicator 20 is rotated and retracted, machining and detection are not affected, and the rotatable dimension of the dial indicator 20 is more, so that the adjustment can be well carried out according to different gear positions of different crankshafts 30. The device can be directly installed on any old-fashioned grinding machine, and can be used for checking the gear of the crankshaft 30 without stopping, so that certain convenience can be provided for workshops using the old-fashioned grinding machine for production, and the production efficiency can be improved to a certain extent.
In this embodiment, the counterweight device is connected with the connecting plate 14; the counterweight device comprises a counterweight rod 16 connected with the connecting plate 14 and a counterweight 17 arranged at the end part of the counterweight rod 16; the weight 17 is located on the same side of the connecting plate 14 as the dial gauge 20. The outer wall of the counterweight rod 16 is provided with threads, and the counterweight 17 is in threaded connection with the counterweight rod 16. Specifically, even if the gear-opening position of the crankshaft 30 is directly below the dial indicator 20, since the connecting rod 15 and the dial indicator 20 cannot be in a straight line, the connecting rod may be slightly fluctuated to some extent due to gravity or the action of the cooling liquid, and the probe 22 of the dial indicator 20 cannot be ensured to be stably clamped therein, at this time, the probe 22 of the dial indicator 20 can be abutted against the gear-opening position of the crankshaft 30 through the counterweight 17 by arranging the counterweight rod 16 and the counterweight 17 on the connecting plate 14, so that the probe 22 of the dial indicator 20 is more stable. And the weight 17 is screw-coupled with the weight rod 16 so that the position of the weight 17 can be adjusted according to the difference of the crank shaft 30 and the shift position.
In this embodiment, the device further comprises a pair of stop collars 12 respectively arranged at two ends of the sleeve 11, a threaded hole formed in the side wall of the stop collars 12, and a fastening bolt 13 in threaded connection with the threaded hole; both ends of the sleeve 11 are in sliding connection with the limiting sleeve 12. Specifically, the stop collar 12 is mainly used to limit the axial movement of the sleeve 11 along the support rod 10, so that after the stop collar 12 is fixed, the sleeve 11 can be rotated very smoothly, and no additional bolts are required to be arranged on the sleeve 11 to fix the sleeve 11. In addition, the fastening bolt 13 with a longer length is used, so that after the fastening bolt 13 is screwed, the connecting rod 15 can be directly lapped on the fastening bolt 13 when the dial indicator 20 is not needed, and the dial indicator 20 is convenient to place (as shown in fig. 4).
In this embodiment, the device further comprises a connecting block for connecting the connecting rod 15 and the dial indicator 20 and rod 21; the connecting rod 15 and the gauge rod 21 are respectively arranged at two ends of the connecting block; the axis of the connecting rod 15 and the axis of the watch bar 21 are parallel to each other. The connecting block comprises a pair of oppositely arranged clamping blocks, and the pair of clamping blocks are connected through a connecting bolt 19; a pair of clamping blocks is used to clamp the connecting rod 15 and the watch bar 21. Specifically, due to the structural limitation of the dial indicator 20, the connecting rod 15 cannot be directly connected with the dial indicator 20 (thus, the dial indicator 20 is convenient to replace or maintain in a later period), and after the connecting bolt 19 is unscrewed, the extension length of the probe 22 of the dial indicator 20 can be adjusted as required.
The support bar 10, the connecting plate 14 and the connecting rod 15 in this embodiment are all made of stainless steel. In particular, since the processing environment is complex and includes oil stains, coolant, and the like, a metallic material having good corrosion resistance is required.
In summary, the device for checking the gear opening of the crankshaft 30 on line by the general grinder of the embodiment can be well adjusted according to different gear opening positions of different crankshafts 30. The device can be directly installed on any old-fashioned grinding machine, and can be used for checking the gear of the crankshaft 30 without stopping, so that certain convenience can be provided for workshops using the old-fashioned grinding machine for production, and the production efficiency can be improved to a certain extent.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
