Abstract
Description
Technical Field
[0001] This utility model relates to the field of universal joint fork processing technology, specifically to a chamfering device at the end of the universal joint fork spindle. Background Technology
[0002] The spindle of a universal joint fork is usually cut to the required length by a cutting mechanism. After cutting, the edge of the spindle end face is relatively sharp and usually needs to be chamfered. However, existing chamfering devices usually have a fixed angle and can only produce chamfers with a fixed tilt. Utility Model Content
[0003] To address the shortcomings of the prior art, this utility model proposes a chamfering device for the end of the universal joint fork spindle.
[0004] To achieve the above-mentioned technical effects, the present invention adopts the following solution:
[0005] A chamfering device for the end of a universal joint fork spindle includes a frame. The frame is equipped with a rotary clamping mechanism, a chamfering mechanism located in front of the rotary clamping mechanism, and a moving mechanism. The rotary clamping mechanism is used to clamp a horizontally placed universal joint fork and rotate it vertically. The rotary clamping mechanism is mounted on the moving mechanism and moves toward the chamfering mechanism. The chamfering mechanism includes a mounting head. The mounting head is inclined on the side facing the rotary clamping mechanism and is equipped with a grinding plate. The mounting head has a first hinge portion and a second hinge portion located above the first hinge portion on the side away from the rotary clamping mechanism. The first hinge portion is hinged to the frame, and the second hinge portion is hinged to one end of a connecting rod. The other end of the connecting rod is hinged to the telescopic end of a first cylinder horizontally mounted on the frame.
[0006] In a preferred embodiment, the grinding plate is detachably mounted on the mounting head by bolts.
[0007] In a preferred embodiment, the rotary clamping mechanism includes a rotary mechanism and a clamping mechanism. The rotary mechanism includes a column mounted on a movable mechanism, a horizontal rotating column mounted on the column, the rotating column being rotatably mounted on the column, a mounting plate connected to the end of the rotating column near the grinding mechanism, a clamping mechanism mounted on the mounting plate, and a motor connected to the end of the rotating column away from the grinding mechanism.
[0008] In a preferred embodiment, the moving mechanism includes a guide rail horizontally mounted on a frame, a moving plate slidably mounted on the guide rail, and the moving plate being driven to move by a second cylinder.
[0009] In a preferred embodiment, both ends of the guide rail are provided with protruding stop blocks.
[0010] Compared with existing technologies, the beneficial effects are:
[0011] This utility model has a simple structure and is easy to use. The universal joint fork is fixed on the rotating clamping mechanism, the main shaft faces the chamfering mechanism and rotates, and is driven to move towards the chamfering mechanism through the moving mechanism. When the main shaft touches the inclined grinding plate, the chamfering process begins. When the chamfering angle needs to be changed, the first cylinder pushes the mounting head to change the inclination, so that the chamfering angle can be changed arbitrarily.
