Description
Technical Field
The utility model relates to a railway vehicle accessory adds clamping apparatus specifically is elasticity side bearing side inclined plane processing positioning fixture of freight train locomotive.
Background
Along with the continuous development of railway passenger and goods transportation, the running speed of a freight car locomotive is continuously improved, higher and higher requirements are provided for the running performance of the freight car locomotive, and in order to effectively inhibit the oscillating snaking motion and the side rolling vibration of a vehicle, improve the stability and the stationarity of the high-speed running of the freight car locomotive and reduce the damage to a line, an elastic side bearing body is required to be installed on the freight car locomotive. As figure 1, the elasticity side bearing body includes two bowl form bodies 1 of arranging side by side, bowl form body 1's height is the same, and all is vertical arrangement, bowl form body 1's bottom all is the opening form, all there is connecting portion between the oral area and the bottom of two adjacent one sides of bowl form body 1, there is boss 2 on one of them bowl form body 1 lateral wall, boss 2 is located and keeps away from that section of connecting portion bowl form body 1 lateral wall, the boss 2 side of keeping away from bowl form body 1 is the inclined plane, processing has the through-hole on the inclined plane, this inclined plane is the side inclined plane 3 of the elasticity side bearing body. When the elastic side bearing body of the freight car locomotive is processed, the side inclined surface 3 of the elastic side bearing body needs to be polished. The general positioning mechanism of ordinary lathe can not fix a position the elasticity side bearing body. In the prior art, a numerical control locomotive is adopted to polish the side inclined surface 3 of the elastic side bearing body, and the processing cost is higher.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an elasticity side bearing side inclined plane processing positioning fixture, the processing cost who adopts this anchor clamps is lower.
In order to solve the problems, the following technical scheme is provided:
the utility model discloses a characteristics of elasticity side bearing side inclined plane processing positioning fixture are including the bottom plate, there is the backup pad that the slope was arranged on the bottom plate, one side of the backup pad that the obtuse angle that backup pad and bottom plate formed corresponds is fixed with the screw rod, the screw rod is perpendicular with the backup pad, all there are bar briquetting and nut on the screw rod, the bar briquetting is perpendicular with the screw rod, the length of bar briquetting is greater than the external diameter of bowl shape oral area in the elasticity side bearing body, there is the through-hole at the middle part of bar briquetting, the bar briquetting overlaps on the screw rod through this through-hole, and the aperture of this through-hole is greater than the width.
And reinforcing ribs are arranged between one side of the supporting plate corresponding to an acute angle formed by the supporting plate and the bottom plate.
By adopting the scheme, the method has the following advantages:
because the utility model discloses an elasticity side bearing side inclined plane processing positioning fixture includes the bottom plate, has the backup pad on the bottom plate, and one side of backup pad is fixed with the screw rod, and the screw rod is perpendicular with the backup pad, all has bar briquetting and nut on the screw rod, and the bar briquetting is perpendicular with the screw rod, and the length of bar briquetting is greater than the external diameter of bowl body oral area in the elasticity side bearing body, has the through-hole on the middle part of bar briquetting, and the bar briquetting is on the screw rod through this through-hole cover, and the aperture of this through-hole is greater than the width of screw rod and is. When in use, the positioning clamp is arranged at a corresponding position of the bedplate of the machine tool through the bottom plate. When the device works, the nut and the strip-shaped pressing block are taken down firstly; then, the side slope of the elastic side bearing body faces upwards and is placed on the supporting plate, and the screw rod penetrates through a bowl body of the elastic side bearing body; then, sequentially installing a strip-shaped pressing block and a nut, screwing the nut, and tightly pressing and fixing the elastic side bearing body on the supporting plate through the strip-shaped pressing block; and finally, starting the machine tool, and processing the side inclined surface of the elastic side bearing body positioned above. After the fixture is used for fixing the elastic side bearing body, the side slope of the elastic side bearing body is positioned above the fixture and can be machined by a common machine tool, so that the machining cost is greatly reduced.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 2 and 3, the utility model discloses an elasticity side bearing side inclined plane processing positioning fixture includes bottom plate 4, there is backup pad 5 that the slope was arranged on bottom plate 4, backup pad 5 is fixed with screw rod 6 with one side of backup pad 5 that the obtuse angle that bottom plate 4 formed corresponds, screw rod 6 is perpendicular with backup pad 5, all there are bar briquetting 7 and nut 8 on the screw rod 6, bar briquetting 7 is perpendicular with screw rod 6, bar briquetting 7's length is greater than the external diameter of bowl-shaped body oral area in the elasticity side bearing body, there is the through-hole at bar briquetting 7's middle part, bar briquetting 7 overlaps on screw rod 6 through this through-hole, and the aperture of this through-hole is greater than the width of screw rod 6 and is less than the internal. And a reinforcing rib is arranged between one side of the supporting plate 5 corresponding to the acute angle formed by the supporting plate 5 and the bottom plate 4.
When the device works, the nut 8 and the strip-shaped pressing block 7 are taken down firstly. Next, the side slope of the elastic side bearing body is upward and placed on the supporting plate 5, and the screw 6 is passed through a bowl of the elastic side bearing body. And then, sequentially installing a strip-shaped pressing block 7 and a nut 8, screwing the nut 8, and tightly pressing and fixing the elastic side bearing body on the supporting plate 5 through the strip-shaped pressing plate to finish fixing.
