Description

Driven bevel gear drilling equipment

Technical Field

The invention relates to a machining technology, in particular to a driven bevel gear drilling device.

Background

At present, when a driven bevel gear hole group is machined, the adopted tool structure comprises a bottom plate, a limiting block, a spring expansion sheet, a gland, a screw and a locking nut. During machining, the locking nut is screwed, the pressing cover is stressed on the spring expansion sheet, the spring expansion sheet is opened, and therefore the inner hole of the bevel gear is clamped for machining. The tool has the following defects: the workpiece is directly placed on the bottom plate, so that the bottom plate is easy to wear, and the tool needs to be completely removed when the bottom plate is polished, thereby wasting time and labor; the tool is manually clamped, the clamping and the loosening of the workpiece are completed by manually screwing and loosening the locking nut, and the assembly of an automatic production line cannot be realized.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide the driven bevel gear drilling device which can solve the problem of automatic clamping of the driven bevel gear and realize the assembly of an automatic production line.

The technical scheme for realizing the purpose of the invention is as follows:

the utility model provides a driven bevel gear drilling equipment, includes hydraulic pressure station, high pressure fuel pipe, coupling, bottom plate, hydro-cylinder body, cushion, spring expansion piece, clamp ring, gland, piston rod and lock nut, is different with prior art:

the piston rod is arranged in the oil cylinder body, the pipe joint and the cushion block are fixed on the bottom plate, the bottom plate is respectively provided with an oil inlet hole and an oil outlet hole, the oil inlet hole and the oil outlet hole are connected with the hydraulic station through a high-pressure oil pipe and the pipe joint, and the inner holes of the spring expansion sheet and the compression ring are matched with the positioning shaft diameter of the oil cylinder body and are sleeved on the oil cylinder; the gland and the locking nut are sleeved on the piston rod, and the tool is clamped by adopting a hydraulic clamping method.

The cushion block is subjected to surface carburization, so that the hardness is high and the cushion block is not easy to wear.

One end of the high-pressure oil pipe is communicated with the hydraulic station through a pipe joint, and the other end of the high-pressure oil pipe is connected with the bottom plate through an oil inlet and an oil outlet.

The invention has the beneficial effects that: the cushion block is subjected to surface carburization treatment, so that the hardness is high, the cushion block is not easy to wear, and the cushion block is convenient to disassemble, assemble and repair; the driven bevel gear is clamped by hydraulic pressure, so that the assembly and disassembly are convenient, and the assembly of an automatic production line can be realized.

Drawings

Fig. 1 is a schematic structural view of a driven bevel gear drilling device according to an embodiment of the present invention.

In the figure: 1. the hydraulic station comprises a hydraulic station 2, a high-pressure oil pipe 3, a pipe joint 4, a bottom plate 5, a sealing ring 6, an oil cylinder body 7, a sealing ring 8, a compression ring 9, a piston rod sealing ring 10, a piston rod 11, a locking nut 12, a gland 13, a spring washer 14, a workpiece 15 and a cushion block.

Detailed Description

The invention is further illustrated but not limited by the following figures and examples.

Example (b):

as shown in fig. 1, a driven bevel gear drilling device comprises a hydraulic station 1, a high-pressure oil pipe 2, a pipe joint 3, a bottom plate 4, a sealing ring 5, an oil cylinder body 6, a sealing ring 7, a compression ring 8, a piston ring sealing ring 9, a piston rod 10, a lock nut 11, a gland 12, a spring washer 13, a workpiece 14 and a cushion block 15, wherein the piston rod 10 is installed on the oil cylinder body 6, and the oil cylinder body 6, the pipe joint 3 and the cushion block 15 are fixed on the bottom plate 4; the bottom plate 4 is respectively provided with an oil inlet hole and an oil outlet hole, the oil inlet hole and the oil outlet hole are respectively communicated with the high-pressure oil pipe 2 through the pipe joint 3, the high-pressure oil pipe 2 is communicated with the hydraulic station 1, and the inner holes of the spring expansion sheet and the compression ring 8 are matched with the positioning shaft diameter of the oil cylinder body 6 and are sleeved on the oil cylinder body 6; the gland 12 and the locking nut 11 are sleeved on the piston rod 10.

When the hydraulic tool is used, the piston rod and the oil cylinder body are installed, then the oil cylinder body, the pipe joint and the cushion block are fixed on the bottom plate, then the bottom plate is fixed on a workbench of a machine tool, the bottom plate is connected with a hydraulic station through an oil pipe, and a clamping and releasing program of the hydraulic tool is set in a machining program.

During machining, a driven bevel gear to be machined is placed on a clamp, a machining program is started, a hydraulic tool acts, a piston rod is pulled downwards under the stress of hydraulic pressure, a pressing cover and a pressing ring are stressed on spring expansion pieces, the spring expansion pieces are spread, and therefore an inner hole of the driven bevel gear is clamped automatically for machining; after the machining is finished, the hydraulic tool acts, the piston rod pushes upwards, the spring expansion sheet is reduced after the stress is removed, and therefore the workpiece is automatically released.
