Problems solved by technology

[0007] In the above processing method, the operation of the drilling jig is cumbersome, and the production of the drilling jig itself is also very cumbersome, and each time a shaft part is processed, it is necessary to design and manufacture a set of drilling jigs for it.
These defects are undoubtedly the main reasons affecting the machining accuracy and machining efficiency of shaft parts.

Embodiment Construction

[0022] The jig of the invention can process at most six shaft parts at the same time, and can process various types of shaft parts without distinction. The specific structure is as image 3 with Image 6 As shown, it includes a bottom plate 6 provided with a plurality of parallel T-slots, and V-shaped blocks 5 connected to each T-slot respectively through positioning keys, and the two sides of the V-shaped grooves of the V-shaped blocks are respectively fixed with adjusting pads by screws. Block 4. In the figure, there are bolt holes between two adjacent T-shaped slots on the bottom plate 6, and bolts and nuts; Positioning piece 3. It can be seen from the figure that there are six T-shaped grooves, and six shaft parts 1 to be processed are clamped at the same time.

[0023] In addition, if Figure 4 As shown, the positioning key includes a rectangular lower positioning block 7 and a threaded positioning block 8 connected by threads.

[0024] The present invention can mat...

Abstract

The invention discloses an adjustable drilling jig for a shaft. The adjustable drilling jig comprises a bottom plate (6) and V-shaped blocks (5), wherein a plurality of parallel T-shaped grooves are formed in the bottom plate (6), and the V-shaped blocks (5) are connected with the T-shaped grooves through positioning keys respectively. Adjusting cushion blocks (4) are fixed to the two side faces of a V-shaped groove of each V-shaped block through screws respectively. The portion, between every two adjacent T-shaped grooves, of the bottom plate (6) is provided with a bolt hole, a bolt and a nut. The bolts penetrate through a pressing plate (2). In addition, positioning pieces (3) are arranged at the same side ends of the T-shaped grooves in the bottom plate (6). The adjustable drilling jig for the shaft has the advantages of being convenient to adjust, simple in workpiece feeding operation and workpiece discharging opening, good in universality, high in positioning accuracy and production efficiency and the like.

Description

technical field [0001] The invention relates to a jig for machining shaft parts, more specifically, a jig for drilling shaft parts. Background technique [0002] Track rollers and guide wheels are an integral part of crawler-type traveling mechanisms such as bulldozers and excavators. They either bear the weight of the fuselage, or guide the chain crawler to run, so they play a vital role in the normal operation of the crawler walking mechanism. Because the crawler-type walking mechanism is widely used in construction machinery, it is mostly used in harsh environments such as ore mining and construction excavation. In order to ensure the service life of the rollers and guide wheels, their processing has strict and systematic requirements. [0003] In the "three major parts" of the supporting wheel and the guide wheel - the body, the shaft and the cover. Such as figure 1 As shown, the most critical part in the machining of shaft parts is the machining of the two pin holes...
