Description

Technical Field

[0001] This utility model relates to the technical field of cutting devices, and in particular to a cutting device for a motor cover. Background Technology

[0002] Traditional motor cover cutting devices typically have a self-rotating steering seat and a cutting blade located on one side of the steering seat. After the motor cover is fixed to the steering seat and clamped, the motor controls the rotation of the motor cover via a synchronous belt. The cutting blade then moves close to the motor cover to complete the cutting. However, the cutting blade cuts at the same position each time, which leads to excessively high temperature at the blade edge, causing the blade to become dull. This results in an uneven end face of the cut motor cover and a tendency to produce burrs. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the technical solution adopted by this utility model is: a cutting device for motor cover, including a worktable, a steering seat, a motor, a fixing mechanism and a cutting mechanism disposed on the worktable, the worktable is rotatably connected to the steering seat, and the motor is connected to the steering seat through a synchronous belt.

[0004] The fixing mechanism includes a fixing frame, a movable plate, a first hydraulic cylinder, and a follower pressure plate. The fixing frame is slidably connected to the movable plate. The fixing frame is located above the movable plate and connected to the first hydraulic cylinder for controlling the up and down movement of the movable plate. The output end of the first hydraulic cylinder is rotatably connected to the follower pressure plate, and the follower pressure plate is coaxially distributed above the steering seat.

[0005] The cutting mechanism includes a fixed seat, a movable seat, a linear guide rail, a second hydraulic cylinder, a rotating shaft, and a cutting wheel. The movable seat is slidably connected to the worktable via the linear guide rail, and the fixed seat is connected to a second hydraulic cylinder for controlling the feed amount of the movable seat. The movable seat is rotatably connected to a cutting wheel for cutting the workpiece via a rotating shaft.

[0006] Using the above technical solution, during processing, the stamped protective cover workpiece is placed with its opening facing downwards on the steering seat. The first hydraulic cylinder controls the follower pressure plate to move downwards, so that the protective cover workpiece is pressed tightly between the steering seat and the follower pressure plate. At this time, the second hydraulic cylinder controls the moving seat to move towards the steering seat, so that the cutting wheel approaches the surface of the protective cover workpiece and cuts. Through the force of the rotation of the protective cover workpiece, the cutting wheel and the protective cover workpiece rotate relative to each other. Compared with a fixed cutting blade structure, the cutting position of the cutting wheel is dispersed, which makes it heat up faster and improves the service life of the cutting device. After cutting, the second hydraulic cylinder, the motor, and the first hydraulic cylinder are reset in sequence, and the cut finished product can be directly taken out. After processing a certain number of protective cover workpieces, the waste is piled up on the steering seat for easy collection at one time, which meets the requirements for material recycling.

[0007] The present invention is further configured such that the steering seat includes a steering rod, a chuck, a spring and a buffer rod. The steering rod is rotatably connected to the worktable, one end of the steering rod is connected to the motor, and the other end is detachably connected to a chuck for mounting workpieces. The steering rod is slidably connected to a buffer rod, and a spring is provided between the steering rod and the buffer rod.

[0008] Furthermore, the steering rod has a stepped portion, and the stepped portion has threaded holes distributed in a circle. The chuck has an outer contour that matches the workpiece, and the chuck is threadedly connected to the steering rod through the threaded holes.

[0009] Furthermore, the steering rod is provided with a groove, and the buffer rod is slidably connected to the groove through the chuck, with a vent hole in the center of the buffer rod.

[0010] Using the above technical solution, when the protective workpiece is mounted on the machine, the protective workpiece is sleeved on the chuck and abuts against the buffer rod. When the first hydraulic cylinder presses down, the protective workpiece moves to the designated position, so that the cutting position of the cutter wheel is consistent. Through the buffering effect of the spring, the protective workpiece is prevented from being deformed by pressure.

[0011] The present invention is further configured such that the fixing frame includes a fixing plate and columns disposed around the fixing plate, the fixing plate is fixedly connected to the workbench through the columns, the moving plate is slidably connected to the columns through a linear bearing, the first hydraulic cylinder is fixedly connected to the fixing plate, and the output end of the first hydraulic cylinder passes through the fixing plate and is connected to the follower pressure plate.

[0012] Furthermore, the follow-up pressure plate includes an upper pressure plate, a lower pressure plate, and a screw sleeve. The output end of the first hydraulic cylinder is fixedly connected to the moving plate through the upper pressure plate, and the lower pressure plate is rotatably connected to the upper pressure plate through the screw sleeve.

[0013] By adopting the above technical solution, when the protective cover workpiece is pressed tightly between the steering seat and the follower pressure plate, the motor controls the steering seat to drive the protective cover workpiece and the lower pressure plate to rotate simultaneously, so as to avoid the upper surface of the protective cover workpiece being scratched by the follower pressure plate, and make the surface of the motor cover after painting smoother.

[0014] The present invention is further configured such that a sensor for detecting the position of the movable seat is provided on one side of the fixed seat.

[0015] Using the above technical solution, a triangularly distributed photoelectric sensor is provided on one side of the fixed base. The photoelectric sensors at both ends detect the positions of the two endpoints of the moving base during cutting and resetting, respectively, and the photoelectric sensor in the middle is used to detect whether the moving base is located on the moving path, thus meeting the requirements of automated control.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The semi-automated cutting process reduces the skill requirements for operators, resulting in smooth, burr-free cuts and improving the efficiency of cutting motor covers.

[0018] 2. The force of the rotating workpiece under the cover causes the cutter wheel to rotate relative to the workpiece under the cover. Compared with a fixed cutter structure, the cutting position of the cutter wheel is dispersed, which makes it heat up faster and improves the service life of the cutting device.

[0019] 3. The finished products after cutting can be taken out directly. After processing a certain number of protective cover parts, the waste is stacked on the steering seat so that the waste can be collected at one time and the material can be recycled.

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Attached Figure Description
