Description

Technical Field

[0001] This utility model relates to the field of machining, specifically to an automatic deburring device for stator screw caps. Background Technology

[0002] Stator screw caps are generally used in fully enclosed compressors. They are usually made of plastic and are mainly used to cover the head of the stator screw to prevent noise caused by the screw colliding with the housing due to vibration during compressor operation. Covering the screw with the screw cap can reduce collision noise. Screw caps are generally mass-produced by injection molds, so their surface inevitably has burrs. In order to avoid the burrs from having an adverse effect on the compressor, a deburring process should be performed before assembly. Existing deburring equipment has low production efficiency and cannot meet the needs of mass production of screw caps. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the prior art and provide an automatic deburring device for stator screw caps to improve production efficiency.

The deburring device includes a slide groove, a slider A is installed in the slide groove, a cylinder A is installed at one end of the slider A, and two slots are provided on the slider A. The shape of the slots matches the shape of the stator screw cap, and a through hole is provided at the bottom of the slots. Two deburring stations are provided on the slide groove, and the two deburring stations are symmetrically arranged with the material storage trough as the center line. The deburring station is provided with a pushing mechanism and a first cutter.

[0005] Furthermore, each of the two deburring stations is equipped with a second cutter, the cutting direction of which is parallel to the length direction of the chute and is arranged toward the storage tank.

[0006] Furthermore, the ejector mechanism includes a cylinder C, with a push rod mounted on the top of the piston rod of the cylinder C. The top of the push rod has a boss, which is used to press against the bottom surface of the stator screw cap. A positioning post is provided on the boss, and the diameter of the positioning post matches the inner hole of the stator screw cap.

[0016] See Figure 1-6This embodiment describes an automatic deburring device for stator screw caps, comprising a vibrating feeding plate 1, a material storage trough 2 at the outlet of the vibrating feeding plate 1, and a deburring device 3 at the outlet end of the material storage trough 2. The deburring device 3 includes a slide groove 34, in which a slider A32 is installed. A cylinder A31 is installed at one end of the slider A32. The slider A32 has two slots 321, the shape of which matches the shape of the stator screw cap. The bottom of the slots 321 has a through hole. The slide groove 34 has two deburring stations, with the material storage trough 2 as the center line. The two deburring stations are symmetrically arranged, with the distance between the two slots 321 being half the distance between the two deburring stations. Each deburring station is equipped with a pushing mechanism and a first cutter 35. The pushing mechanism includes a linear track B arranged perpendicular to the slide 34, a slider B39 mounted on the linear track B, and a cylinder B36 mounted at one end of the linear track B. The output end of the cylinder B36 is connected to the slider B39, and a lifting mechanism is fixedly mounted on the slider B39. The lifting mechanism is used to hold the workpiece in place so that it contacts the first cutter 35. The cylinder B36 is used to push the lifting mechanism, causing the workpiece to be deburred by the first cutter 35. Furthermore, each of the two deburring stations is equipped with a second cutter 33. The cutting direction of the second cutter 33 is parallel to the length direction of the slide 34 and faces the storage tank 2. This invention, by setting the second cutter 33, and ensuring that the workpiece is cut in two directions with two blades, ensures that the burrs are completely removed. Furthermore, the ejector mechanism includes a cylinder C38, with an ejector rod 310 mounted on the top of the piston rod of the cylinder C38. The top of the ejector rod 310 has a boss for supporting the bottom surface of the stator screw cap. A positioning post is provided on the boss, with its diameter matching the inner hole of the stator screw cap. This invention avoids the ejector rod 310 directly hitting the cutter and damaging it by setting the boss to support the bottom surface of the workpiece instead of directly supporting its top surface, thus ensuring the stability of the equipment. Furthermore, the deburring station is equipped with a discharge groove 37. One end of the discharge groove 37 is fixedly connected to the slide 34, and the other end is inclined downwards. The bottom surface of the discharge groove 37 has a discharge slot 371 corresponding to the ejector rod 310.The working principle of this utility model is as follows: The stator screw cap is continuously conveyed to the storage tank 2 by the vibrating feeding plate 1. The cylinder A31 drives the slider A32 to move back and forth along the slide groove 34. The two deburring stations work alternately; when one deburring station is working, the other is paused. When loading is needed, one slot 321 of the slider A32 aligns with the outlet of the storage tank 2, and the other slot 321 aligns with the first deburring station. At this time, the workpiece at the frontmost end of the storage tank 2 is squeezed into the slot 321 for loading. After loading, the cylinder A31 moves the workpiece to the second deburring station. During the movement, the workpiece passes through the second cutter 33 of this station, and the top surface of the workpiece is automatically cut laterally. Simultaneously, the other slot 321 moves to a position aligned with the storage tank 2 to load the second workpiece. At this time, the cylinder A31 pauses, and the second deburring station enters the working state. First, the cylinder C38 lifts the workpiece upwards. The top boss of the push rod 310 passes through the through hole of the slot 321 and pushes the workpiece upward. Then, cylinder B36 pushes cylinder C38 to move towards the first cutter 35, realizing the automatic cutting of the top surface of the workpiece longitudinally for the second cut. After two cuts, the burrs are basically removed. At this time, the processed workpiece is moved to the unloading slot 371 of the unloading groove 37 by the drive of cylinder B36. Then, cylinder C38 retracts. The bottom surface of the workpiece is larger than the unloading slot 371, so it is blocked by the unloading groove 37 and automatically slides down the unloading groove 37 for collection. Then, cylinder B36 retracts and cylinder C38 returns to its original position to prepare for processing the next workpiece. Cylinder A31 moves again to move the second workpiece to the first deburring station. At the same time, the empty slot 321 moves to the storage tank 2 to automatically load the third workpiece. At this time, the first deburring station enters the working state, and the second deburring station pauses its operation. This cycle repeats, so as to realize the batch automatic deburring of stator screw caps.
