Abstract
The utility model provides a fixing device for processing wear ring excircle, it mainly comprises base, location slider, apron, fastening screw, reset spring. The base is provided with three movable grooves for the positioning sliding block to be placed correspondingly to the positioning sliding block, two ends of the positioning sliding block are respectively provided with a boss, the middle of the positioning sliding block is provided with a lug, the lug corresponds to the three movable grooves arranged on the base and can slide back and forth along the axial direction along the three grooves on the base, side walls at two ends of the positioning sliding block are inclined planes in a shape like a Chinese character 'ba' in a transverse cutting mode, a reset spring is arranged in a middle groove of the movable groove of the positioning sliding block, a cover plate is fixed on the upper end face of the movable groove of the positioning sliding block through. It has the effects that: the positioning performance is good, the fixation is stable, and the product processing qualification rate is high and can reach more than 97%.
Description
The technical field is as follows: the utility model relates to a forge piece product finish machining auxiliary device of machining trade, especially a fixing device for processing wear ring excircle.
Background art: the wear ring is a part installed at the tail part of a trailer type automobile, is a fastening piece for connecting two automobiles, and is a fixing device for turning the excircle of the wear ring forging, which is the most difficult to process when the blank of the wear ring forging is processed into a finished product because the wear ring is in a crescent shape. In the prior art, a cylindrical fixing part with the diameter matched with the inner diameter of a wear ring is turned, the wear ring is buckled on the cylindrical fixing part, and a screw is used for pressing a wear ring forging piece to start processing. The method has the following defects: the qualification rate of the processed products is very low (about 60 percent), the fixing device has no positioning function, the wear ring can rotate around the center of a cylinder of the fixing device at will, and the workpieces are easy to deviate during clamping, so that the processed products are often eccentric, and the qualification rate of the products is very low.
The invention content is as follows: the utility model aims to provide a to the not enough that present wear ring exists when its excircle is processed, and provide a fixing device for processing wear ring excircle, it has the advantage that the positioning performance is good, and the product processing qualification rate is high.
The purpose of the utility model can be realized by the following technical proposal, a fixing device for processing the excircle of a wear ring is characterized in that the fixing device comprises a base, a positioning slide block, a cover plate, a fastening screw rod and a reset spring; the base is provided with three movable grooves for the positioning sliding block to be placed correspondingly to the positioning sliding block, two ends of the positioning sliding block are respectively provided with a boss, the middle of the positioning sliding block is provided with a lug, the lug corresponds to the three movable grooves arranged on the base and can slide back and forth along the axial direction along the three grooves on the base, side walls at two ends of the positioning sliding block are inclined planes in a shape like a Chinese character 'ba' in a transverse cutting mode, a reset spring is arranged in a middle groove of the movable groove of the positioning sliding block, a cover plate is fixed on the upper end face of the movable groove of the positioning sliding block through.
The utility model has the effects that: the positioning performance is good, the fixation is stable, and the product processing qualification rate is high and can reach more than 97 percent; this both ends lateral wall that lies in location slider is the inclined plane of "eight" font, and two front end inside walls of wear ring are for falling "eight" word shape, so the wear ring is in fixed assembly propulsion, two opening front end inside walls can with two lateral walls in close contact with of location slider, the wear ring is pushed forward more, the tighter of card between location slider and the wear ring, can not push forward again until the wear ring, make the wear ring compress tightly the location by the location slider, do not allow the wear ring front end to take place the rotation about, thereby reach the accurate purpose in location.
The present invention is further explained below with reference to the accompanying drawings and embodiments:
description of the drawings:
FIG. 1 is a schematic structural view of the present invention assembled with a workpiece;
FIG. 2 is a schematic cross-sectional view of FIG. 1;
FIG. 3 is a schematic structural view of the base of the present invention;
FIG. 4 is a schematic structural view of the positioning slider of the present invention;
fig. 5 is a schematic structural diagram of the workpiece according to the present invention.
The specific implementation mode is as follows:
referring to the attached figure 1, the fixing device for machining the excircle of the wear ring mainly comprises a base 1, a positioning slide block 2, a cover plate 3, a fastening screw rod 4 and a return spring 5. Three grooves are arranged on the base 1. The positioning slide 2 is provided with two bosses 21 and one projection 22. The two bosses 21 are respectively arranged corresponding to the two side grooves of the base 1, and the lug 22 is arranged corresponding to the middle groove of the base 1. The side walls of the two ends of the positioning slide block 2 are inclined planes transversely cut into a splayed shape. The return spring 5 is placed in the middle groove of the base 1. The positioning slide block 2 can slide back and forth along three grooves on the base 1 in the axial direction. The cover plate 3 is fixed on the upper end surfaces of the three grooves of the base 1 through screws, and the fastening screw rod 4 is in threaded connection with the base 1.
The operation flow is as follows: the assembled device is arranged on three claws of a fixed chuck of a numerical control lathe, and the three claws of the fixed chuck are clamped on a cylinder at the lower end of a base 1 of the device. And loosening the fastening screw rod 4, inserting the wear ring forging blank 6 into the semi-cylinder at the upper end of the base 1, and pushing the wear ring forging blank 6 along the opening direction of the wear ring forging blank 6 until the wear ring forging blank is not pushed. And (5) tightly pressing the fastening screw rod 4, completing workpiece clamping, and starting the numerical control lathe to carry out cylindrical turning machining operation. After the machining is finished, the fastening screw rod 4 is unscrewed, and the reset spring 5 pushes out the wear ring forging blank 6 and resets the positioning slide block 2.
