Abstract
The utility model relates to a clamp for machining a planet carrier hole of a gearbox, which comprises a bottom plate. The center of the upper surface of the bottom plate is connected with a positioning mandrel. At least three corner oil cylinders are uniformly distributed on the bottom plate around the positioning mandrel, and the outer ends of the pressing plates of the corner oil cylinders face inwards. And supporting blocks are fixed on the bottom plates corresponding to the outer ends of the pressing plates. The method is characterized in that: the bottom plate at one side of the positioning mandrel is provided with an elastic pin which is positioned on a diameter line overlapped with the interval bisector of a pair of adjacent corner oil cylinders. By adopting the fixture, the axial positioning of the planet carrier hole of the gearbox can be realized, the circumferential positioning of the planet carrier hole of the gearbox can be realized, and the processing quality of the planet carrier hole of the gearbox can be ensured. The fixing device is suitable for fixing the carrier when the planet carrier hole of the gearbox is machined.
Description
Technical Field
The utility model relates to a clamp. In particular to a positioning clamp for fixing a wheel carrier when a shaft hole on the wheel carrier of a planetary gear transmission mechanism of a gearbox is machined.
Background
It is known in the machining art that the gearbox planet carrier is one of the main components of a planetary gear. The planetary gear is arranged on the wheel carrier through the axle holes on the wheel axle and the wheel carrier. Wherein, when processing the shaft hole on the wheel carrier, need to fix the wheel carrier.
Currently, the jigs used to position the axle holes on the planet carrier of the gearbox contain a bottom plate. The center of the upper surface of the bottom plate is connected with a positioning mandrel. Corner oil cylinders are uniformly distributed on the bottom plate around the positioning mandrel, and the outer ends of the pressing plates of the corner oil cylinders face inwards. And supporting blocks are fixed on the bottom plates corresponding to the outer ends of the pressing plates. By adopting the fixture, only axial positioning of the planet carrier hole of the gearbox can be realized, circumferential positioning of the planet carrier hole of the gearbox can not be realized, and the processing quality of the planet carrier hole of the gearbox is difficult to ensure.
Disclosure of Invention
The utility model aims to solve the problem of providing a clamp for machining a planet carrier hole of a gearbox. By adopting the fixture, the axial positioning of the planet carrier hole of the gearbox can be realized, the circumferential positioning of the planet carrier hole of the gearbox can be realized, and the processing quality of the planet carrier hole of the gearbox can be ensured.
The above problems to be solved by the present utility model are realized by the following technical solutions:
the utility model relates to a clamp for processing a planet carrier hole of a gearbox, which comprises a bottom plate. The center of the upper surface of the bottom plate is connected with a positioning mandrel. At least three corner oil cylinders are uniformly distributed on the bottom plate around the positioning mandrel, and the outer ends of the pressing plates of the corner oil cylinders face inwards. And supporting blocks are fixed on the bottom plates corresponding to the outer ends of the pressing plates. The method is characterized in that: an elastic pin is arranged on the bottom plate at one side of the positioning mandrel and is positioned on a diameter line which coincides with the interval bisector of a pair of adjacent corner oil cylinders.
According to the further improved scheme, cushion blocks are arranged between the corner oil cylinder and the bottom plate.
According to a further improvement scheme, through holes are formed in the bottom plate corresponding to the elastic pins, and an oil cylinder is connected to the lower surface of the bottom plate corresponding to the through holes. The oil cylinder is vertically arranged, and the outer end of a piston rod of the oil cylinder passes through the through hole through a connecting rod and then is connected with the lower end of the elastic pin.
According to a further improvement scheme, the upper end of the elastic pin is connected with a diamond-shaped pin head.
According to the scheme, the center of the upper surface of the bottom plate is connected with the positioning mandrel. At least three corner oil cylinders are uniformly distributed on the bottom plate around the positioning mandrel, and the outer ends of the pressing plates of the corner oil cylinders face inwards. And supporting blocks are fixed on the bottom plates corresponding to the outer ends of the pressing plates. Through the corner oil cylinder and the positioning mandrel, the axial positioning of the planet carrier hole can be realized. And because the elastic pin is arranged on the bottom plate at one side of the positioning mandrel, the elastic pin is positioned on a diameter line which coincides with the interval bisector of a pair of adjacent corner oil cylinders. Through the elastic pin, circumferential positioning of the planet carrier hole of the gearbox can be realized. Therefore, the utility model has the axial positioning function and the circumferential positioning function, and can greatly improve the machining quality of the planet carrier hole of the gearbox.

Detailed Description
As shown in fig. 1 and 2, the jig for machining a carrier hole of a transmission of the present utility model includes a base plate 1, and a positioning mandrel 6 is provided at the center of the upper surface of the base plate 1. Six corner oil cylinders 3 are uniformly distributed on the bottom plate 1 around the positioning mandrel 6. Cushion blocks 2 are arranged between the corner cylinders 3 and the bottom plate 1. The outer ends of the pressing plates 4 of the corner oil cylinders 3 are all inward. And supporting blocks 5 are fixed on the bottom plate 1 corresponding to the outer ends of the pressing plates 4. An elastic pin 9 is arranged on the bottom plate 1 at one side of the positioning mandrel 6 and is positioned on a diameter line which coincides with the interval bisector of a pair of adjacent corner oil cylinders 3. Wherein, a through hole is processed on the bottom plate 1 corresponding to the elastic pin 9, and the lower surface of the bottom plate 1 corresponding to the through hole is connected with an oil cylinder 11. The oil cylinder 11 is vertically arranged, and the outer end of a piston rod of the oil cylinder is connected with the lower end of the elastic pin 9 after passing through the through hole through the connecting rod 12. The upper end of the elastic pin 9 is connected with a diamond-shaped pin head 8. During operation, axial positioning of the planet carrier hole of the gearbox can be realized through the corner oil cylinder 3 and the positioning mandrel 6. The circumferential positioning of the gearbox planet carrier hole is also achieved by means of the elastic pins 9.
