Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.
As shown in fig. 1, the utility model discloses an utensil is examined to bent axle balancing piece excircle radius qualification degree, it includes base 1, fixed plate 2, percentage table 3, two bracing pieces 4, two supporting shoes 5, two locating pieces 6, two bolts 7, slide rail 8, slider 9, dead lever 10 and screw 11.
The base 1 is a U-shaped block, a fixing plate 2 and a sliding rail 8 are fixed on the base 1, and the base 1 is used for fixing the whole device.
The fixing plate 2 is used for fixing two support rods 4. Specifically, two first through holes are formed in the fixed plate 2, the two support rods 4 are respectively inserted into the two first through holes to enable the two support rods 4 to move relative to the fixed plate 2, and two support blocks 5 are respectively fixed at the upper ends of the two support rods 4. Therefore, the crankshafts are placed on the two supporting blocks 5, the two supporting rods 4 can move relative to the fixed plate 2, and the two supporting blocks 5 and the crankshafts on the two supporting rods 4 can move up and down. Two locating pieces 6 are all fixed on fixed plate 2 and are located two bracing pieces 4 one side respectively, a first screw hole that runs through is all seted up to the position that corresponds bracing piece 4 on two locating pieces 6, two bolts 7 spiro union are on two first screw holes. So, to the great bent axle of the big or small difference of different models, can turn round two bolts 7 of pine, two bracing pieces of slip 4 and then adjust the distance of bent axle balancing piece to percentage table 3, make the gauge outfit of percentage table 3 contact with the bent axle balancing piece, then screw up two bolts 7, make two bracing pieces 4 fixed, and then make the bent axle fixed.
The dial indicator 3 is fixed on the sliding block 9, and the indicator head points to the direction of the supporting rod 4 and is used for measuring the crankshafts placed on the two supporting blocks 5.
The two supporting blocks 5 are used for supporting the crankshaft, and the two supporting blocks 5 are respectively fixed at the upper ends of the two supporting rods 4. Specifically, the two support blocks 5 are both semicircular, so that the crankshaft can be fixed and prevented from falling off from the two support blocks 5.
The slider 9 is located the slide rail 8 and can slide relative to the slide rail 8, the percentage table 3 is fixed on slider 9, can make the percentage table 3 slide from side to side from this, and the bent axle of fixing on two supporting shoes 5 can reciprocate, consequently can make the gauge outfit of percentage table 3 contact with the bent axle balancing piece, makes percentage table 3 can measure the reading. Specifically, slide rail 8 quantity is two and relative setting, percentage table 3 is located between two slide rails 8, so, the percentage table can the horizontal slip. Another embodiment is that, the slide rail 8 quantity is four and two liang of relative settings, percentage table 3 is located four slide rails 8 middles, and like this, the percentage table also can slide from side to side.
The fixing rod 10 is used for connecting the two support rods 4, and two ends of the fixing rod 10 are respectively fixed with the two support rods 4 to enable the distances between the two support blocks 5 and the fixing plate 2 to be equal, so that the crankshaft is prevented from sliding on the two support blocks 5 due to the fact that the heights of the two support blocks 5 are different.
The screw 11 is used for fixing the dial indicator 3 on the sliding block 9, specifically, a second through hole is formed in the sliding block 9, the dial indicator 3 is inserted into the second through hole, a second threaded hole is formed in the sliding block 9 outwards at the position of the second through hole, and the screw 11 is screwed on the second threaded hole to fix the dial indicator 3 on the sliding block 9. Therefore, when the screw 11 is screwed down, the dial indicator 3 can be fixed on the sliding block 9, and when the screw 11 is unscrewed, the dial indicator 3 can move in the sliding block 9 so as to adjust the distance between the dial indicator 3 and the two supporting blocks 5. For crankshafts of different models, if the size difference of the crankshafts is small, the heights of the two supporting blocks 5 do not need to be adjusted, only the height of the dial indicator 3 needs to be adjusted, the gauge head of the dial indicator 3 can be in contact with a balance block on the crankshafts, and the excircle radius qualification degree of the balance block of the crankshafts is detected.
The working principle of the crankshaft balance block excircle radius qualification degree checking fixture comprises the steps of firstly placing a qualified crankshaft and balance blocks on two supporting blocks 5, loosening screws 11 to adjust the height of a dial indicator 3, sliding a sliding block 9 at the same time to enable a gauge head of the dial indicator 3 on the sliding block to be in contact with the balance blocks on the crankshaft, then screwing the screws 11 to fix the dial indicator 3, then rotating the crankshaft back and forth by using two hands to enable the dial indicator 3 to detect two ends of an excircle of the balance blocks on the crankshaft, and directing the pointer of the dial indicator 3 to a zero position when the pointer of the dial indicator 3 reaches the highest point of an excircle measuring surface of the balance blocks on the crankshaft. And taking out the qualified crankshaft and balance block, placing the crankshaft and balance block to be tested on the two supporting blocks 5, rotating the crankshaft and balance block to be tested back and forth, recording the deviation of the reading of the pointer on the dial indicator 3 relative to the zero position when the pointer of the dial indicator 3 reaches the lowest point of the eccentric excircle of the balance block on the crankshaft to be tested, wherein the deviation is qualified within the tolerance range. For crankshafts of different models, if the size difference of the crankshafts is small, the heights of the two supporting blocks 5 do not need to be adjusted, only the height of the dial indicator 3 needs to be adjusted, if the size of the crankshaft is greatly different, the head of the dial indicator 3 cannot be contacted with the balance weight on the crankshaft only by adjusting the height of the dial indicator 3, after the qualified crankshaft and balance blocks are placed on the two supporting blocks 5, the two bolts 7 are loosened, the heights of the two supporting rods 4 are adjusted, simultaneously, the sliding block 9 is slid to ensure that the gauge head of the dial indicator 3 on the sliding block is contacted with the balance block on the crankshaft, then two bolts 7 are screwed down to fix the two support rods 4, then the crankshaft is rotated back and forth by two hands, so that the dial indicator 3 can measure the two ends of the excircle of the balance weight on the crankshaft, when the pointer of the dial indicator 3 reaches the highest point of the excircle measuring surface of the balance block on the crankshaft, the pointer of the dial indicator 3 is pointed to a zero position. And taking out the qualified crankshaft and balance block, placing the crankshaft and balance block to be tested on the two supporting blocks 5, rotating the crankshaft and balance block to be tested back and forth, recording the deviation of the reading of the pointer on the dial indicator 3 relative to the zero position when the pointer of the dial indicator 3 reaches the lowest point of the eccentric excircle of the balance block on the crankshaft to be tested, wherein the deviation is qualified within the tolerance range.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
