Description

Technical Field

[0001] The present invention belongs to the technical field of chamfering machines, and particularly relates to a shaft tube chamfering machine for processing automotive drive shafts. Background Art

[0002] The automotive drive shaft is an important component in the automotive transmission system, mainly used to transmit the power generated by the engine to the wheels to drive the vehicle forward. The drive shaft mainly consists of three parts: a shaft tube, a telescopic sleeve, and a universal joint. Among them, the shaft tube is the main part of the drive shaft, responsible for carrying the power and transmitting it to the wheels. The telescopic sleeve is a component connecting the shaft tube and the universal joint, which can be telescoped as needed to adapt to different working conditions. The universal joint is a key component connecting the front axle half shaft and the wheels, responsible for driving and steering. The shaft tube chamfering machine is mainly used for chamfering the edges of shaft tubes, pipes, or other tubular materials before or after welding or processing.

[0003] In the patent with the application number 201810248637.0, an automated seamless steel pipe chamfering machine is disclosed. By setting two rotating wheels at the feeding port of the chamfering machine body, the top connection line of the rotating wheels is collinear with the feeding port of the chamfering machine body. The outer edge of the rotating wheels is arrayed with notches for the steel pipe to be clamped in. The rotating wheels are connected with a driving mechanism for driving their intermittent one-way rotation, and a feeding frame inclined towards the rotating wheels is arranged on one side of the rotating wheels. A pushing mechanism for pushing the steel pipe towards the chamfering machine body is arranged at one end of the rotating wheel far from the chamfering machine body. The steel pipe on the feeding frame rolls to the rotating wheels, and the steel pipe tangent to the rotating wheels is embedded in the notches of the rotating wheels. The driving mechanism drives the rotating wheels to rotate, and the steel pipe rotates to the top of the rotating wheels accordingly. The rotating wheels stop, and the pushing mechanism pushes the steel pipe into the chamfering machine body for chamfering and cutting. Combining the above application and comparing it with the existing chamfering machines at the same time, during the use process, the chamfering is completed by the rapid cutting of the cutting tool. During the process of the tool machining the chamfer, the rapidly rotating tool is likely to throw out the chips generated by the cutting. At the same time, since a certain temperature will be generated during cutting, safety accidents are likely to occur when the chips are thrown out, thus affecting the practicability and safety of the machine. For this reason, we propose a shaft tube chamfering machine for processing automotive drive shafts. Summary of the Invention

[0004] The purpose of the present invention is to provide a shaft tube chamfering machine for processing automotive drive shafts, so as to solve the problem proposed in the above background art that when comparing with the existing chamfering machines, during the use process, the chamfering is completed by the rapid cutting of the cutting tool. During the process of the tool machining the chamfer, the rapidly rotating tool is likely to throw out the chips generated by the cutting. At the same time, since a certain temperature will be generated during cutting, safety accidents are likely to occur when the chips are thrown out, thus affecting the practicability and safety of the machine.

[0005] To achieve the above object, the present invention provides the following technical solution: A shaft tube chamfering machine for processing automobile drive shafts, including a chamfering workbench, on the top of which a chamfering cutting seat is installed. On both sides of the chamfering cutting seat, chamfering cylinders are symmetrically installed, as well as a cross-moving cylinder for driving the chamfering cylinders to move. On the top of the chamfering cutting seat, a lifting pressure cylinder is installed. On the top of the chamfering workbench, at the rear surface of the chamfering cutting seat, a feeding rack is installed. On the front surface of the chamfering cutting seat, a protective winding box is installed. Inside the protective winding box, a winding rod is installed. At both ends of the winding rod, winding springs are installed. A protective net is wound on the winding springs. At the bottom of the protective net, a retractable pull rod is installed. At the bottom of the chamfering cutting seat, a cleaning push plate is installed.

[0006] Preferably, at the bottom of the retractable pull rod, sleeve buckles are symmetrically arranged, and at the bottom of both sides of the front surface of the chamfering cutting seat, sleeve hooks are fixedly installed.

[0007] Preferably, when the protective net is drawn out and covered on the front surface of the chamfering cutting seat, it is connected and limited by the sleeve buckle and the sleeve hook.

[0008] Preferably, a servo motor is fixedly installed at the bottom of the chamfering workbench. At one end of the servo motor, a gear is installed on the top of the chamfering workbench. At one end of the cleaning push plate, a cleaning displacement rod is arranged. At one side end of the cleaning displacement rod, a rack is arranged.

[0009] Preferably, a sliding seat is also installed on the top of the chamfering workbench. The cleaning displacement rod passes through and is limited in the sliding seat, and between the cleaning displacement rod and the servo motor, they are also installed through the meshing of the gear and the rack.

[0010] Preferably, at the bottom of both ends inside the chamfering cutting seat, displacement slide rails are arranged. When the cleaning push plate reciprocates at the bottom of the chamfering cutting seat, it is limited by the displacement slide rails.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) By setting this chamfering machine with a protective winding box structure, when using this device for chamfering processing, the protective net in the protective winding box can be drawn out and covered on the front surface of the chamfering cutting seat, avoiding safety accidents caused by flying debris during chamfering cutting work. Moreover, the protective net is set in a retractable and winding manner, which is convenient for winding and unwinding while improving the practicability and safety of this device;

[0013] (2) Additionally, during the processing of this device, a large amount of debris will accumulate at the bottom of the chamfer cutting seat during long-term processing, which is inconvenient to clean. Through the pushing structure driven by the servo motor, when using this device for chamfer processing, the debris accumulated at the bottom of the chamfer cutting seat during cutting can be removed by the cleaning push plate while processing. This not only facilitates cleaning but also avoids the excessive accumulation of debris affecting the chamfer, thereby improving the practicality of this device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1 Pressing block; 107, cutting tool; 108, shaft tube support block

[0020] Please refer to Figure 1 and Figure 2, the present invention provides a technical solution: during the processing of the drive shaft of an automobile, through chamfering treatment, burrs and sharp parts at the edge can be removed, making the edge of the shaft tube smoother, facilitating subsequent processes such as welding and assembly, and improving the aesthetics and safety of the product. A shaft tube chamfering machine for processing automobile drive shafts places the shaft tube on the feeding rack 105 during operation. The shaft tube falls onto the shaft tube support block 108 through the feeding rack 105 and is pushed into the inside of the chamfering cutting seat 101 by a cylinder. Then, the lifting and pressing cylinder 102 operates to drive the pressing block 106 to descend, fixing the shaft tube on the shaft tube support block 108. Then, the transverse movement cylinder 103 operates to push the chamfering cylinder 104 to move transversely, and when the chamfering cylinder 104 moves transversely, it drives the cutting tool 107 to rotate. The fixed shaft tube is cut and chamfered by the rotating cutting tool 107. It includes a chamfering workbench 100, a chamfering cutting seat 101 is installed on the top of the chamfering workbench 100, chamfering cylinders 104 are symmetrically installed on both sides of the chamfering cutting seat 101, and a transverse movement cylinder 103 for driving the chamfering cylinder 104 to move, a lifting and pressing cylinder 102 is installed on the top of the chamfering cutting seat 101, a feeding rack 105 is installed on the top of the chamfering workbench 100 at the rear surface of the chamfering cutting seat 101, a protective winding box 200 is installed on the front surface of the chamfering cutting seat 101, a winding rod 201 is installed inside the protective winding box 200, winding springs 202 are installed at both ends of the winding rod 201, a protective net 203 is wound on the winding springs 202, a retractable pull rod 204 is installed at the bottom of the protective net 203, and a cleaning push plate 300 is installed at the bottom of the chamfering cutting seat 101. When using the machine in this application for chamfering processing, the shaft tube is placed on the feeding rack 105 and enters the chamfering cutting seat 101 through the feeding component, and then through the drive of the transverse movement cylinder 103 and the chamfering cylinder 104, the cutting and chamfering are completed. During the cutting operation of this device, in order to prevent the debris generated by the rotation and cutting of the tool from flying out of the chamfering cutting seat 101, a protective winding box 200 is installed on the front surface of the chamfering cutting seat 101. During operation, the protective net 203 wound on the winding rod 201 inside the protective winding box 200 can be pulled out through the retractable pull rod 204. During the rotation of the winding rod 201, the winding springs 202 at both ends are wound to generate a winding force. The pulled-out protective net 203 covers the front surface of the chamfering cutting seat 101, and after the other end of the protective net 203 is pulled out through the retractable pull rod 204, it can be hung on the hook at the bottom of the front surface of the chamfering cutting seat 101 through the buckle 205. The flying out of debris from the chamfering cutting seat 101 during the processing can be prevented by the pulled-out protective net 203, thus avoiding safety accidents and improving the safety and practicality of this machine.

[0021] Specifically, socket buckles 205 are symmetrically and fixedly installed at the bottom of the retractable pull rod 204, and socket hooks are fixedly installed at the bottoms of both sides of the front surface of the chamfer cutting seat 101. When the protective net 203 is pulled out and covered on the front surface of the chamfer cutting seat 101, it is connected and limited by the socket buckles 205 and the socket hooks. When the sleeved socket buckles 205 are separated from the socket hooks, the retractable spring 202 that generates a retracting force through winding can automatically retract the protective net 203 into the protective retraction box 200.

[0022] Embodiment 2
