Problems solved by technology

[0003] At present, there are a variety of clamping tools for drive shaft processing on the market, such as a vertical machining fixture for half-shaft parts disclosed in application number 201720893204.1, and an automobile drive shaft disclosed in application number 201821715500.3 Semi-automatic fixtures for processing, a fixture for drive shaft production disclosed in application number 201621001060.6, and a drive shaft drilling fixture disclosed in application number 201820914120.6, etc. Use when drilling on the side of one end of the
When it is necessary to drill a hole at one end of the drive shaft, the production personnel simply position the drive shaft and then drill the hole. However, due to the simple positioning, the drilling angle and the drilling position cannot be accurately controlled. As a result, the drilling accuracy is low and the failure rate is high

Embodiment 1

[0043] Such as figure 1 As shown, the clamping tool for drilling the drive shaft includes a rectangular base plate 10 and a turntable 11 and a tailstock 12 respectively fixed on the base plate 10. The turntable 11 and the tailstock 12 are arranged oppositely, and the turntable 11 is close to the base plate. One of the short sides of the bottom plate 10, and the tailstock 12 is close to the other short side of the bottom plate 10. The side opposite to the turntable 11 and the tailstock 12 is fixedly connected with a mounting base 13 with an L-shaped vertical section.

[0044] Such as figure 1 and figure 2 As shown, the upper surface of the substrate 1 is fixed with a support 2, and the side of the support 2 is provided with a positioning hole 2c1 for the drive shaft 15 to pass through. The positioning hole 2c1 is opened along the length direction of the bottom plate 10. The upper surface of the substrate 1 A block 3 is also fixed and a pressing mechanism 4 is provided. The ...

Embodiment 2

[0054] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, the elastic positioning assembly 5 includes a locking rod slidably arranged in the cavity 2a and a support spring sleeved on the locking rod , the embedded part 5a1 is fixedly connected to the upper end of the locking rod, and the locking rod always has a tendency to move upward under the elastic force of the support spring.

Embodiment 3

[0056] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, the pressing mechanism 4 includes a push cylinder fixed on the upper surface of the substrate 1, and the end of the piston rod of the push cylinder is fixedly connected with a The push plate can push the drive shaft 15 to move towards the block 3 when the piston rod of the cylinder is pushed out.

Abstract

The invention provides a clamping tool for drilling a drive shaft and belongs to the technical field of clamps. The clamping tool solves the problem how to improve the drilling precision of the drive shaft. The clamping tool comprises a base plate and a support fixed to the base plate. The support is provided with a locating hole for the drive shaft to penetrate through is formed in the support in a penetrating manner. The base plate is further provided with a stop block and an ejecting and pressing mechanism. The stop block and the ejecting and pressing mechanism are located on the two sides of the support in the forming direction of the locating hole. The clamping tool is characterized in that the locating hole is a spline hole, a tooth missing position is arranged on the portion, between the two spline teeth, of the inner side wall of the locating hole, a cavity communicating with the lower portion of the locating hole is formed in the support, an elastic locating assembly is arranged in the cavity, and the elastic locating assembly partially extends into the lower portion of the locating hole under the elastic force effect of the elastic locating assembly. According to the clamping tool for drilling the drive shaft, while accuracy of the drilling position is ensured, the drilling precision is improved, and the production efficiency of enterprises is improved.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and relates to a clamping tool, in particular to a clamping tool for driving shaft drilling. Background technique [0002] The drive shaft is an important part of the power transmission system in the car. Its function is to transmit the power of the engine to the wheels together with the gearbox and drive axle, so that the car can generate driving force. When producing the drive shaft, according to the design requirements, it involves the processing of various places on the drive shaft, such as machining external splines on the drive shaft or machining holes on the end face of the drive shaft. Sometimes, it is even necessary to drill a hole at one end of the drive shaft according to requirements. There are specific requirements for the drilling angle and the drilling position to the end face of the drive shaft, especially for the drilling angle. External splines are in a positional or angular r...
