Description

Technical Field

[0001] The utility model relates to the technical field of inner hole chamfering machines, in particular to an inner hole chamfering machine used for processing tubular parts. Background Art

[0002] A chamfering machine is a small precision machine tool that is professionally used for chamfering in mold manufacturing, hardware machinery, machine tool manufacturing, hydraulic parts, valve manufacturing, and textile machinery, as well as for removing burrs from products processed by milling and planing. Some tubular parts require chamfering of the inner holes, but most chamfering machines require a special chamfering machine for chamfering because the chamfering mechanism is too large.

[0003] Existing, such as Chinese patent publication No. CN101890519B discloses a chamfering machine, which includes a frame, a support base and a workpiece positioning seat are arranged on the frame, a movable rocker arm is pivotally provided on the support base, one end of the movable rocker arm is provided with a motor, and the other end is provided with a conical countersinking tool, a movable rocker arm height pre-adjuster is arranged on the frame between the support base and the motor, the power output end of the motor is connected to the countersinking tool through a reducer, and a connecting rod is arranged on the movable rocker arm between the countersinking tool and the support base, the connecting rod is connected to a cross bar, one end of the cross bar is pivotally arranged on the cross bar base, and the other end is provided with a foot pedal. The above-mentioned chamfering machine extends the movable rocker arm into the tubular workpiece, aligns the countersinking tool with the hole to be deburred, and uses the conical countersinking tool to quickly grind off the burrs on the inner wall of the tube. It not only has a simple structure and low cost, but also is easy to operate, has high processing accuracy and high work efficiency.

[0004] Although the above patent uses a conical countersink tool to quickly grind away burrs on the inner wall of the tube, it is not only simple in structure and low in cost, but also easy to operate, with high processing precision and high work efficiency. However, there are still some shortcomings. For example, the device requires manual fixation of the tubular part, and the waste chips generated during fixation are very likely to be inhaled into the lungs, endangering the life of the workers. At the same time, the countersink of the device can only chamfer specific positions of the tubular part. Once other inner holes of the tubular part need to be chamfered, the position of the tubular part needs to be manually adjusted, which is very inconvenient. Therefore, it is necessary to propose a new type of inner hole chamfering machine for tubular part processing. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that in the prior art, tubular parts need to be fixed manually, and the waste chips generated during the fixing are very likely to be inhaled into the lungs, endangering the life of the workers. At the same time, the countersink drill in the prior art can only chamfer specific positions of the tubular parts. Once other inner holes of the tubular parts need to be chamfered, the position of the tubular parts needs to be adjusted manually, which is very inconvenient. The problems raised in the background technology are solved by providing an automatically adjustable position countersink drill and a rotating mechanism.

[0009] Preferably, a warning light is fixedly installed on one side of the outer wall of the support frame, and the warning light is electrically connected to the servo motor, so that after the chamfering of the tubular part body is completed, when the servo motor controls the clamping plate to no longer clamp the tubular part body, the warning light can be used to remind the worker that the tubular part body can be removed.

[0010] Preferably, a third electric telescopic rod is fixedly inserted into the inner wall of the V-shaped frame, and an adjustment block is fixedly installed on the output end of the third electric telescopic rod, so that a part of the tubular body can be controlled to be located inside the clamping mechanism through the adjustment block, which is convenient for clamping with the tubular body.

[0014] 1. In the utility model, by setting a moving block and a clamping mechanism, the tubular body is placed on a V-shaped frame, and then the first electric telescopic rod is started to drive the countersink to move into the tubular body, and then the entire lifting block can be driven downward by the first electric telescopic rod to fit the countersink with the tubular body, and then the first motor can be started to drive the countersink to rotate, and the inner hole of the tubular body can be chamfered. After the chamfering is completed, the tubular body is driven to rotate 90° by the clamping mechanism, and the other inner holes of the tubular body can be chamfered, thereby avoiding the problem that manual fixation may affect the life and health of workers. At the same time, mechanical rotation and fixation also liberate manpower and improve chamfering efficiency.

[0015] 2. In the utility model, by setting up a feed rack, a certain number of tubular component bodies can be directly placed inside the feed rack first, so that when workers take out and chamfer the tubular component bodies, they can directly replenish materials, and then by setting a spring damper, it is convenient for the first electric telescopic rod to adjust the lifting block to move up and down, and the moving block is damped to prevent the lifting block from vibrating and causing the entire countersink to produce cracks on the internal chamfer of the tubular component body, thereby improving the quality of the chamfering. Finally, an adjustment block is also provided to prevent the tubular component body from falling on the V-shaped frame. The tubular component body can be adjusted to the inside of the clamping mechanism through the adjustment frame to facilitate subsequent operations. BRIEF DESCRIPTION OF THE DRAWINGS
