Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing, in particular to a deburring device for the processing of balance weights. Background Art

[0002] An air-conditioning compressor balance weight refers to a device used to balance the vibration and imbalance generated during the operation of an air-conditioning compressor. After the balance weight is produced, a shot blasting machine is required to deburr the balance weight. Before use, the balance weight is placed on the rubber belt inside the casing, the turning door is closed, and the rubber belt is driven to rotate by the motor and the round roller, so that the balance weight keeps turning. The steel balls shot out from the shot blasting machine will hit the surface of the balance weight to deburr the balance weight. After the processing of the balance weight is completed, the balance weight continues to turn on the surface of the rubber belt for a period of time to separate the steel balls from the balance weight. Then the turning door is opened, the rubber belt is rotated in the reverse direction, and the balance weight can be taken out.

[0003] After the processing of the balance weight is completed, it is necessary to rotate inside the casing for a period of time to separate the balance weight from the steel balls. The separation time is relatively long and the separation efficiency is low. Therefore, the present application provides a deburring device for the processing of balance weights to meet the requirements. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a deburring device for the processing of balance weights to solve the problems of long separation time between the balance weight and the steel balls and low separation efficiency.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A deburring device for the processing of balance weights includes a casing and a shot blasting machine installed on the top of the casing. Inside the casing, a rubber belt is rotationally connected by a round roller. A through hole is opened on the side of the casing, and the through hole is used for feeding and discharging.

[0030] As Figures 1-6 shown, an embodiment of the present utility model provides a deburring device for processing balance weights, including a machine shell 1 and a shot blasting machine 2 installed on the top of the machine shell 1. Inside the machine shell 1, a rubber belt is rotatably connected through a round roller. A through hole is opened on the side of the machine shell 1 for feeding and discharging materials. A turning door is hinged at the through hole of the machine shell 1. It further includes:

[0031] A screening mechanism 3, the screening mechanism 3 includes a fixed seat 4 fixed on one side of the through hole of the machine shell 1. A pull rod 5 movably penetrates through the side of the fixed seat 4 away from the machine shell 1. A socket 7 is fixed at the end of the pull rod 5. The socket 7 is slidably connected to the inner wall of the fixed seat 4. A first spring 6 is sleeved on the surface of the pull rod 5. One end of the first spring 6 away from the socket 7 is fixed to the inner wall of the fixed seat 4, and the other end of the first spring 6 is fixed to the side of the socket 7. A slot 8 is opened at the top of the socket 7. A plug rod 9 is movably inserted into the inner wall of the slot 8. A housing 10 is fixed at the top of the plug rod 9. A groove 11 is opened at the top of the housing 10. A grille 12 is fixed to the inner wall of the groove 11. A deflector 17 is fixed to the housing 10 in the direction close to the machine shell 1. The deflector 17 is attached to the surface of the rubber belt. A roller 16 is rotatably connected to the housing 10 in the direction close to the rubber belt. The roller 16 is attached to the surface of the rubber belt. The cross-sectional shape of the roller 16 is oval. A flow channel 13 is opened on the inner wall of the groove 11. An inclined plate 14 is opened on the inner wall of the groove 11. The bottom of the inclined plate 14 is located at the inlet of the flow channel 13.

[0032] As Figure 2 and Figure 3 shown, in this embodiment, a receiving groove 20 is opened on the inner wall of the slot 8. A second spring 21 is fixed to the inner wall of the receiving groove 20 in the direction away from the plug rod 9. A limiting ball 22 is fixed to the other end of the second spring 21. A positioning groove 19 corresponding to the receiving groove 20 is opened on the surface of the plug rod 9. The second spring 21 drives the limiting ball 22 to fit into the positioning groove 19. After the limiting ball 22 is clamped inside the positioning groove 19, it can position the plug rod 9 and prevent the plug rod 9 from moving upward during use.

[0033] As Figure 2 shown, in this embodiment, a sphere is provided on the side of the pull rod 5 away from the fixed seat 4. The sphere increases the contact area with the hand, facilitating the pulling of the pull rod 5.

[0034] AsFigure 4 As shown in the figure, in this embodiment, a guide rod 18 is horizontally fixed on the inner wall of the groove 11, and the socket 7 is movably sleeved on the surface of the guide rod 18. The guide rod 18 guides the socket 7 horizontally to prevent the socket 7 from tilting.

[0035] As Figure 4 shown in the figure, in this embodiment, there are two guide rods 18 in total. The two guide rods 18 are symmetric about the middle of the fixed seat 4. The symmetrically arranged guide rods 18 guide the socket 7 more stably.

[0036] As Figure 2 shown in the figure, in this embodiment, the top of the grille 12 and the top of the housing 10 are in the same plane. The top of the housing 10 is inclined, and the downward position is away from the direction of the machine housing 1, so that the balance weight can slide down along the inclined plane. After the grille 12 and the housing 10 are in the same plane, it can prevent a protrusion from being generated between the two, and prevent the balance weight from being blocked during sliding.

[0037] As Figure 2 shown in the figure, in this embodiment, a square plate 15 is fixed on the side of the housing 10. The square plate 15 is arranged at the outlet of the runner 13. The square plate 15 is inclined, and the steel balls roll down along the square plate 15 into the machine housing 1, preventing the steel balls from falling out of the machine housing 1.

[0038] As Figure 2 shown in the figure, in this embodiment, the gap of the grille 12 is smaller than the size of the balance weight, and the gap of the grille 12 is larger than the diameter of the steel balls thrown by the shot blasting machine 2. The steel balls can fall from the grille 12, while the balance weight will slide down along the grille 12.

[0039] Working principle: Place the balance weight on the rubber belt in the machine housing 1, close the flip door, start the motor, the motor drives the round roller to rotate through the round roller, the round roller drives the rubber belt to rotate, and then the shot blasting machine 2 throws steel balls downward to deburr the balance weight;

[0040] When the balance weight in the machine housing 1 is processed, open the flip door, pull the socket 7 in the direction of the pull rod 5 by a certain distance through the pull rod 5, then align the insertion rod 9 at the bottom of the housing 10 with the slot 8 at the top of the socket 7 and insert it. After the insertion rod 9 is inserted into the slot 8, the spring two 21 in the storage groove 20 will drive the limit ball 22 to abut against the positioning groove 19 to prevent the insertion rod 9 from moving upward. Then release the pull rod 5, and the spring one 6 drives the socket 7 to move away from the direction of the pull rod 5. The socket 7 drives the housing 10 to move through the insertion rod 9, and the housing 10 drives the roller 16 to fit on the surface of the rubber belt through the rotating seat;

[0041] At this time, reverse the rotation of the rubber belt. During the rotation of the rubber belt, the roller 16 will be driven to rotate. Since the roller 16 is elliptical, the roller 16 will move continuously during rotation. The roller 16 will drive the outer shell 10 to move through the rotating seat. At the same time, the reversely rotating rubber belt will drive the balance block to move outward. The balance block and the steel balls will slide down along the diversion plate 17 to the top of the outer shell 10. The steel balls will be sorted out from the grille 12. The steel balls will fall from the grille 12 onto the inclined plate 14. The steel balls will roll along the inclined plate 14 into the flow channel 13. The steel balls will flow out along the flow channel 13. The steel balls will flow back into the casing 1 again through the square plate 15. After the balance block is separated, it can be stored. When separating, there is no need to rotate in the casing 1 for a period of time, which takes less time and has higher efficiency.
