Description
Technical Field
The utility model relates to a tapered roller terminal surface centre bore size measurement device.
Background
The existing bearing parts have a large number of large tapered roller end face drilled center holes, foreign customers have higher requirement precision on the size of the tapered roller center hole, although the tapered roller center hole is machined and formed by a numerical control lathe programming sequence, the center drill bit is consumed and abraded, the size of the center hole of the tapered roller has deviation, if a depth gauge is used for measurement, only the depth can be measured, the error is large, a caliper is used for measuring the opening diameter of the center hole, caliper claws are sometimes not placed correctly, the measured numerical error is large because the center hole has an opening diameter of 60 degrees, so the diameter size deviation marked by the center hole drawing cannot measure an accurate numerical value, a measuring instrument which is suitable for the center hole is not available, a workshop cannot produce quickly, and delivery is carried out on time.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem overcome prior art not enough, provide a tapered roller terminal surface centre bore size measurement device.
The utility model discloses a technical scheme be tapered roller terminal surface centre bore size measurement device, the bow-shaped frame passes through set screw to be fixed on the flat board, and the tight piece of clamp is fixed the bow-shaped frame with the percentage table on, dull and stereotyped central processing through-hole, measures slider and through-hole clearance fit, measures slider upper end and percentage table feeler lever contact, measures the slider and surpasss dull and stereotyped lower surface. And a cross bar screw is also arranged on the side surface of the bow-shaped frame. The upper end of the measuring slide block is provided with a boss, the outer diameter of the boss is larger than the diameter of the through hole, and the lower end of the measuring slide block is provided with a 60-degree conical body.
The measuring slide block can freely slide up and down in the middle through hole of the flat plate, the lower end of the measuring slide block is made into a 60-degree conical body, the angle size of the 60-degree conical body is the same as that of a 60-degree conical angle of the central hole of the roller, a pointer of a dial indicator is calibrated by using a standard part of the central hole size of a conical roller belt and is placed on the end surface of the processed conical roller, the 60-degree conical body slides into the central hole of the roller under the action of gravity of the measuring slide block, the pointer is transmitted through a contact of the dial indicator, and the dial indicator displays the size of a numerical value, so that whether the size of the central hole of the roller is larger or smaller can be known.
The beneficial effects of the utility model are that tapered roller terminal surface centre bore size measurement device has replaced original use depth gauge and slide caliper rule to measure the centre bore, has not only solved the non-uniform problem of large-scale tapered roller centre bore measurement size, has reduced the workman and has operated the degree of difficulty simultaneously, has reduced measuring time, has improved work efficiency.

Fig. 1 is the structure schematic diagram of the tapered roller end face center hole size measuring device of the present invention.
Labeled as: 1-bow rack, 2-fixing screw, 3-flat plate, 3 a-through hole, 4-clamping block, 5-dial indicator, 51-dial indicator feeler lever, 6-measuring slide block, 61-boss, 62-60 degree conical body, 7-cross block screw and 8-tapered roller
Detailed Description
As shown in figure 1, the device for measuring the size of the center hole of the end face of the tapered roller is characterized in that an arched frame 1 is fixed on a flat plate 3 through a fixing screw 2, a dial indicator is fixed on the arched frame 1 through a clamping block 4, a through hole 3a is machined in the center of the flat plate 3, a measuring slide block 6 is in clearance fit with the through hole 3a, the upper end of the measuring slide block 6 is in contact with a contact rod 51 of the dial indicator, and the measuring slide block 6 exceeds the lower surface of the flat. And a cross bar screw 7 is arranged on the side surface of the bow-shaped frame 1. The upper end of the measuring slide block 6 is provided with a boss 61, the outer diameter of the boss 61 is larger than the diameter of the through hole 3a, and the lower end of the measuring slide block 6 is provided with a 60-degree conical body 62.
The measuring slide block can freely slide up and down in the middle of the flat plate, the boss is arranged at the upper end of the measuring slide block, the measuring slide block cannot be separated from the central through hole of the flat plate, the cross rail screw is located above the boss of the measuring slide block, the distance of upward movement of the measuring slide block is limited, the dial indicator is protected from being damaged due to excessive shortening of the contact rod, the device can be prevented from being separated from the flat plate in the carrying process, and the measuring slide block and the dial indicator are protected from being damaged. The lower end of the measuring slide block is made into a 60-degree conical body, the angle size of the 60-degree conical body is the same as that of a 60-degree conical angle of the central hole of the roller, a pointer of a dial indicator is calibrated by using a standard part with the size of the central hole of the conical roller and is placed on the end face of the processed conical roller, the 60-degree conical body slides into the central hole of the roller under the action of gravity, the pointer is transmitted through a contact of the dial indicator, and the dial indicator displays the size of a numerical value, so that whether the size of the central hole of the roller is larger or smaller can be known, and whether the size meets the tolerance requirement of a.
