Detailed Description

The invention is further described with reference to the following figures and examples.

As shown in the figure, this embodiment horizontal lathe work piece strutting arrangement, including pedestal and location support ware, the pedestal comprises lower seat piece 1 and the last seat piece 3 of connecting on lower seat piece through bolt 2 that sets up on the lathe bed guide rail, and the middle part of pedestal is provided with the round hole 4 that supplies the work piece to pass, and the location support ware has evenly arranged four in round hole circumference, and wherein two location support ware symmetrical arrangement are on the pedestal. The positioning support device in the embodiment comprises a support rod 5 in sliding fit with a support body, an adjusting screw 6 arranged on an adjusting seat and used for pushing the support rod to move along the radial direction of a circular hole 4 in the middle of the support body, and a support roller 7 arranged at the end part of a cylindrical support rod, wherein the support rod 5 is a cylindrical rod in the embodiment, although the support rod can also be in other shapes in different embodiments, a guide straight groove is arranged on the outer surface of the cylindrical rod in the embodiment, and a guide flat key in sliding fit with the guide straight groove is arranged on the support body; the guiding flat key is positioned in the support body and is drawn in the attached drawings of the specification. This embodiment horizontal lathe work piece strutting arrangement still includes the center and transfers the ware, the center is transferred the ware including fixing locating pin 8 on the side of lower block, wear on the locating pin and fix backup pad 10 on the side of lower block through screw 9, set up location axle 11 in the backup pad, set up rotor 12 on the location axle and set up the ruler 13 that is used for measuring the top of location support ware to location axle center distance on the rotor, the axle center of location axle coincides with the axle center of chuck, the rotor includes axle sleeve 121 with location axle normal running fit and the ruler cutting ferrule 122 of connecting perpendicularly on the axle sleeve, is provided with the bayonet socket groove with ruler sliding fit and is used for locking the locking screw 14 of ruler on the ruler cutting ferrule, and the limit portion in bayonet socket groove is provided with vernier scale 15, and the extension line of the zero scale mark of vernier scale intersects with the center of location axle.

Before a workpiece is hoisted on a workpiece supporting device of a horizontal lathe, the position of a positioning support of an upper seat block is adjusted according to the outer diameter of the workpiece, and the method comprises the following specific steps: firstly, a support plate of a central alignment device is arranged on a positioning pin on the side surface of a lower seat block, and then the support plate is fixed through a screw; and then the rotating body is rotated to enable the zero scale end of the ruler to point to a supporting roller of a positioning support device on the lower seat block, then the ruler is moved to enable the zero scale end of the ruler to lean against the supporting roller, the distance from the top of the supporting roller to the center of the positioning shaft is obtained through ruler scales and vernier scales, and then the position of the positioning support device is adjusted according to the difference value of the reading and the diameter of the workpiece, so that the distance from the top of the supporting roller to the center of the positioning shaft is consistent with the radius size of the workpiece. In the same way, the distance from the top of the supporting roller of the other positioning support device on the lower seat block to the center of the positioning shaft is adjusted to be consistent with the radius size of the workpiece. After the position of the positioning support device on the lower seat block is adjusted in place, the central aligning device is disassembled, the workpiece can be hoisted on the positioning support device of the lower seat block, then the upper seat block is installed on the lower seat block, and the screw rod of the positioning support device on the upper seat block is rotated to prop the supporting roller on the workpiece.
