Technical Field

[0001] The utility model belongs to the technical field of surface treatment, and particularly relates to a casting surface treatment device. Background Art

[0002] Casting is a metal forming process that generally involves injecting molten metal into a mold and allowing it to cool and solidify into the desired shape. After removing burrs and flash, castings usually need to be subjected to unified surface treatment to improve the uniformity of the casting surface.

[0003] The grinding cavities of existing casting surface grinding treatment devices are usually circular or annular, which is not convenient for batch grinding treatment of long strip-shaped castings. The space utilization rate of the grinding cavity is low, and the surface treatment efficiency of long strip-shaped castings is low. Therefore, a new type of casting surface treatment device is needed. Summary of the Utility Model

[0004] To solve the above problems, the utility model discloses a casting surface treatment device.

[0005] To achieve the above object, the technical solution of the utility model is as follows:

[0006] A casting surface treatment device includes a grinding shell. The annular grinding cavity of the grinding shell is composed of two relatively open semi-ring segments and two straight segments, and the two ends of each straight segment are respectively communicated with the two semi-ring segments. A plurality of dividing mechanisms are arranged on each straight segment of the annular grinding cavity. A vibration and swing mechanism is embedded in the central cavity of the grinding shell. Springs are respectively fixedly connected to the bottoms of the two ends of the grinding shell, and the bottoms of the two springs are jointly connected to a base; each dividing mechanism includes: a connector inserted into the grinding shell, a transverse hole rod fixedly connected to the side wall of the connector and extending into the straight segment of the annular grinding cavity, and a plurality of vertical insertion rods inserted into the through holes of the transverse hole rod.

[0007] As a preferred technical solution of the utility model, a ring is arranged at the top of the vertical insertion rod, and a plurality of through holes linearly and uniformly distributed with respect to itself are arranged on the transverse hole rod.

[0009] As a preferred technical solution of the present utility model, the diameter of the second driving wheel is larger than that of the first driving wheel.

[0010] As a preferred technical solution of the present utility model, each semi-circular segment of the annular grinding cavity is provided with a circulation mechanism, and the circulation directions of the two circulation mechanisms cooperate with each other.

[0011] As a preferred technical solution of the present utility model, each of the circulation mechanisms includes: a lifting pipe fixedly connected to the grinding shell, a spiral inserted into the bottom straight pipe of the lifting pipe, the spiral being coaxially connected to a first driving motor, and the upper part of one end of the spiral close to the first driving motor being exposed out of the lifting pipe.

It should be understood that the following detailed implementation manners are only used to illustrate the present utility model and not to limit the scope of the present utility model.

[0030] Please refer to Figures 1-5 , a casting surface treatment device, including a grinding shell 1. The annular grinding cavity 101 of the grinding shell 1 is composed of two relatively open semi-circular segments and two straight segments, and both ends of each straight segment are respectively communicated with the two semi-circular segments. The semi-circular segments are used for abrasive circulation, and the straight segments are used for processing long strip-shaped castings. A plurality of partition mechanisms 2 are arranged on each straight segment of the annular grinding cavity 101 to separate each long strip-shaped casting and prevent the long strip-shaped castings from concentrating together and affecting the surface treatment. A vibration and swing mechanism 5 is embedded in the central cavity 102 of the grinding shell 1. The vibration and swing mechanism 5 can drive the grinding shell 1 to swing while providing high-frequency vibration, and the vibration and swing together promote the movement of the abrasive in the annular grinding cavity 101. Springs 6 are respectively fixedly connected to the bottom ends of both sides of the grinding shell 1, and the bottoms of the two springs 6 are jointly connected to a base 7. The base 7 is provided with a plurality of through holes for bolt penetration and fixation. The cooperation of the double springs 6 and the vibration and swing mechanism 5 during operation can enable the grinding shell 1 to swing towards both sides of itself.

[0031] Each dividing mechanism 2 includes: a connector 201 inserted into the grinding shell 1. A horizontal hole rod 202 extending into the straight section of the annular grinding cavity 101 is fixedly connected to the side wall of the connector 201. A plurality of vertical insertion rods 203 are inserted into the through holes of the horizontal hole rod 202. A ring is provided at the top of the vertical insertion rod 203, and the ring is used to extract the vertical insertion rod 203. The horizontal hole rod 202 is provided with a plurality of through holes linearly and evenly distributed about itself. The grinding shell 1 is provided with a bayonet adapted to the connector 201. According to the actual shape of the strip-shaped casting, a plurality of vertical insertion rods 203 are inserted into the through holes of the horizontal hole rod 202 to separate the strip-shaped castings from each other, thereby reducing the influence between them during surface treatment.

[0032] The vibration and swing mechanism 5 includes: a second drive motor 501 embedded in the central cavity 102. An eccentric wheel 502 is fixedly connected to the output shaft of the second drive motor 501. A first transmission wheel 503 is coaxially and fixedly sleeved on the output shaft of the second drive motor 501. A V-shaped frame 506 is fixedly connected to the bottom of the grinding shell 1, and a second transmission wheel 505 is rotatably connected to the rotating shaft of the V-shaped frame 506. The rotating shaft of the V-shaped frame 506 and the second transmission wheel 505 are rotatably connected through a bearing. A belt 504 is jointly sleeved on the second transmission wheel 505 and the first transmission wheel 503, and an eccentric block 507 is fixedly connected to the side wall of the second transmission wheel 505. The diameter of the second transmission wheel 505 is larger than the diameter of the first transmission wheel 503, and the diameter of the second transmission wheel 505 is more than five times the diameter of the first transmission wheel 503.

[0033] Each semi-ring section of the annular grinding cavity 101 is provided with a circulation mechanism 3, and the circulation directions of the two circulation mechanisms 3 cooperate with each other for the abrasive to circulate annularly in the annular grinding cavity 101. Each circulation mechanism 3 includes: a lifting pipe 301 fixedly connected to the grinding shell 1. A screw 302 is inserted into the bottom straight pipe of the lifting pipe 301. The screw 302 is coaxially connected to a first drive motor 303, and the upper end of the screw 302 near the first drive motor 303 is exposed out of the lifting pipe 301. The first drive motor 303 is embedded in the installation cavity of the grinding shell 1. The place where the lifting pipe 301 exposes the screw 302 is the feed port, and a baffle 4 is arranged between the feed port and the adjacent dividing mechanism 2. The top of the baffle 4 is slightly higher than the screw 302, and the baffle 4 is used to prevent the strip-shaped casting from contacting the screw 302. The discharge port of the lifting pipe 301 extending upward is flat, which is convenient for increasing the spreading surface of the abrasive.

[0034] Working principle:

[0035] During operation, small-particle abrasives are injected into the annular grinding cavity 101 of the grinding shell 1. Then, a plurality of strip-shaped castings are placed in the abrasives, and all the strip-shaped castings are placed on the straight-line section of the annular grinding cavity 101. Then, several connectors 201 and transverse-hole rods 202 are inserted into the outer wall of the grinding shell 1. Then, several vertical insertion rods 203 are inserted on the transverse-hole rods 202 according to the actual shape of the strip-shaped castings to separate the strip-shaped castings from each other. Then, the second drive motor 501 of the vibration and swing mechanism 5 is started. Driven by the second drive motor 501, the eccentric wheel 502 rotates to drive the grinding shell 1 to vibrate at a high frequency, so as to realize the surface grinding of the strip-shaped castings by the granular abrasives. At the same time, the first transmission wheel 503 fixedly sleeved on the output end of the second drive motor 501 drives the second transmission wheel 505 to rotate through the belt 504. Since the eccentric block 507 rotates at a low frequency together with the second transmission wheel 505, the grinding shell 1 also swings at a low frequency. The vibration and swing jointly promote the movement of the abrasives in the annular grinding cavity 101 while vibrating;

[0036] When the abrasives in the annular grinding cavity 101 move in a ring, the two circulating mechanisms 3 cooperate with each other to drive the abrasives to circulate in a ring. Among them, the first drive motor 303 drives the screw 302 to rotate, and the rotating screw 302 drives the abrasives to enter the lifting pipe 301 and move along the lifting pipe 301, so as to realize the annular circulation of the abrasives. At the same time, the lifting pipe 301 lifts the abrasives at the bottom of the annular grinding cavity 101 to the upper part of the lifting pipe 301, so as to realize the up-and-down circulation of the abrasives.

[0037] It should be noted that the above content only illustrates the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. For those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements all fall within the protection scope of the claims of the present invention.
