Description

Technical Field

[0001] This invention relates to the field of materials processing technology, and in particular to a fully automatic drum-type parts grinding and polishing machine. Background Technology

[0002] There are many mechanical devices available for grinding and polishing parts, but most of them are customized according to the shape of the parts and are suitable for flat surfaces, curved surfaces and chamfers. However, for irregularly shaped or small-sized parts in large quantities, traditional equipment is inefficient and cannot grind in all directions. In this case, a vibratory grinder is generally required.

[0003] For example, patent document CN203993490U describes a vibratory grinding machine that uses an upward-opening tank with a vibrator in the middle. The abrasive and workpiece are added into the tank together, and grinding is achieved through vibration. However, the workpiece and abrasive are not easily separated after grinding, and the workpiece is inconvenient to remove. Another patent document, CN208163390U, describes a high-precision spiral vibratory grinding machine. Based on the above patent documents, it sets spiral intervals in the tank to extend the grinding time of the workpiece. However, the removal and placement of abrasive and parts are still inconvenient. In addition, in traditional vibratory grinding machines, the abrasive and workpiece are generally mixed together. For sharp workpieces, it is easy for them to collide with each other, leaving deep scratches and affecting accuracy. Or, for sheet-like workpieces that are easily stacked together, the workpiece cannot be ground evenly. Summary of the Invention

[0004] In view of the above situation and to solve the problems existing in the prior art, the purpose of this invention is to provide a fully automatic drum-type parts grinding and polishing machine, which can effectively solve the problems of parts colliding with each other and the workpiece and abrasive not being easy to separate during polishing.

[0005] The technical solution includes a horizontally placed cylindrical sand bucket that can rotate; the inside of the sand bucket is hollow, and a sand outlet is opened on the side wall of the sand bucket; a rotating polishing component is fitted on the outside of the sand bucket.

[0006] The polishing assembly includes a filter cartridge fitted outside a sand bucket, a cylindrical outer shell fitted outside the filter cartridge, and multiple radial transverse partitions evenly distributed around the circumference between the outer shell and the filter cartridge; a polishing chamber is formed between two adjacent transverse partitions, and multiple longitudinal partitions are evenly distributed in each polishing chamber, dividing a polishing chamber into multiple polishing units; the outer shell is provided with multiple placement openings corresponding to the polishing chambers, and a detachable arc-shaped baffle is provided at each placement opening.

[0007] The sand outlet is set to one.

[0008] The sand outlets are configured as two evenly distributed around the circumference.

[0009] The sand bucket is fixed with support shafts at both ends. The support shafts are supported by brackets and rotated by a first motor.

[0010] The filter cartridge has solid parts at both ends, which are located on the left and right sides of the outer shell. The solid parts at both ends of the filter cartridge are supported by multiple rollers, which are mounted by a bracket. One of the rollers is driven to rotate by a second motor.

[0011] Each of the polishing chambers has a sliding groove on the left and right side partitions, and an arc-shaped baffle is placed in the sliding groove. The right side wall of the outer shell has multiple clearance holes that correspond one-to-one with the arc-shaped baffles; the arc-shaped baffles pass through the clearance holes.

[0012] This invention offers the following significant advantages: 1. It enables mass grinding, allowing parts to be ground to be placed relatively independently, preventing stacking or collisions. 2. The device automatically adds and flows polishing abrasive through the rotation of the abrasive bucket 1, facilitating abrasive recycling and easy handling of parts. 3. This device is highly customizable, suitable for parts of different sizes, and can be used with either reciprocating or circulating grinding methods. Attached Figure Description

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Depend on Figures 1 to 6The present invention includes a horizontally placed cylindrical sand bucket 1, which is rotatable; the interior of the sand bucket 1 is hollow, and a sand outlet 2 is provided on the side wall of the sand bucket 1; a rotatable polishing component is fitted on the outside of the sand bucket 1.

[0022] The polishing assembly includes a filter cartridge 3 fitted outside the sand bucket 1, a cylindrical outer shell 4 fitted outside the filter cartridge 3, and multiple radial transverse partitions 5 evenly distributed around the circumference between the outer shell 4 and the filter cartridge 3; a polishing chamber 6 is formed between two adjacent transverse partitions 5, and multiple longitudinal partitions 7 are evenly distributed in each polishing chamber 6, which divides a polishing chamber 6 into multiple polishing units 8; the outer shell 4 is provided with multiple placement ports 10 corresponding one-to-one with the polishing chambers 6, and a detachable arc-shaped baffle 9 is provided at each placement port 10.

[0023] To achieve reciprocating grinding, the sand outlet 2 is set to one.

[0024] To achieve rotary grinding, the sand outlet 2 is configured as two evenly distributed circumferentially.

[0025] In order to install and support the sand bucket 1, support shafts 11 are fixed at both ends of the sand bucket 1. The support shafts 11 are supported by brackets and rotated by a first motor.

[0026] To prevent sand leakage and the rotation and installation of the polishing components, the left and right ends of the filter cartridge 3 are solid parts, and the solid parts of the left and right ends of the filter cartridge 3 are placed on the left and right sides of the outer casing 4. The solid parts of the left and right ends of the filter cartridge 3 are supported by multiple rollers 12, and the rollers 12 are mounted by brackets. One of the rollers 12 is driven to rotate by a second motor.

[0027] In order to facilitate the disassembly and installation of the arc-shaped baffle 9, a sliding groove 13 is provided on the horizontal partition 5 on the left and right sides of each polishing chamber 6. The arc-shaped baffle 9 is placed in the sliding groove 13. A plurality of clearance holes corresponding to the arc-shaped baffle 9 are provided on the right side wall of the outer shell 4. The arc-shaped baffle 9 passes through the clearance holes.

[0028] To facilitate the addition of grinding fluid and the replacement of sand, the sand bucket 1 is equipped with a liquid outlet pipe 14 and a sand filling pipe 15. Both the end of the liquid outlet pipe 14 and the sand filling pipe 15 are equipped with end caps, and a filter screen is installed inside the liquid outlet pipe 14.

[0029] Firstly, in this invention, both the sand bucket 1 and the polishing assembly can rotate independently. Grinding particles, i.e. polishing sand, can be added into the sand bucket 1 through the sand adding pipe 15. During actual grinding, grinding liquid can also be added through the sand adding pipe 15 or the liquid outlet pipe 14. After grinding, the grinding liquid is discharged through the liquid outlet pipe 14. The liquid outlet pipe 14 is equipped with a filter screen to ensure that the polishing sand does not flow out.

[0030] Taking the sand outlet 2 on the sand bucket 1 as an example, this describes the reciprocating grinding method.

[0031] After the abrasive is added to the abrasive bucket 1, it will accumulate in the lower part of the abrasive bucket 1 under the action of gravity. By rotating the abrasive bucket 1, the only abrasive outlet 2 is positioned directly above. At this time, the polishing abrasive in the polishing chamber 6 corresponding to the abrasive outlet 2 will fall into the abrasive bucket 1. That is, after the polishing chamber 6 is rotated to the top, abrasive discharge will occur. At this time, the arc-shaped baffle 9 can be pulled out, and the parts to be polished can be placed in the multiple polishing units 8 in the polishing chamber 6. Since each polishing unit 8 is an independent area, one or more parts can be placed in each polishing unit 8, preferably one. Then the arc-shaped baffle 9 is reset.

[0032] As described above, by rotating the outer casing 4, the parts can be placed one by one into the multiple polishing units 8.

[0033] Then, rotate the sand bucket 1 so that the sand outlet 2 on the sand bucket 1 is directly downwards; when the sand outlet 2 is downwards, the polishing sand in the sand bucket 1 will fall into one or more polishing chambers 6 located below; the polishing sand falls into the polishing chambers located below. By driving the outer casing 4 to rotate by the second motor, the polishing sand can be evenly dropped into each polishing unit 8. The rotation speed of the outer casing 4 should be slow, so that the polishing sand in each polishing unit 8 is about two-thirds full.

[0034] Finally, grinding can be carried out. During grinding, the second motor drives the outer casing 4 to rotate back and forth, so that the parts in each unit or the polishing sand can be shaken and ground to achieve polishing of the parts.

[0035] After polishing is complete, you can remove the parts by referring to the method used when placing them in.

[0036] When there are two abrasive outlets 2, a rotary polishing method is used. One outlet 2 is positioned directly above the other. During the grinding process, the abrasive container 1 remains stationary, while the outer casing 4 rotates slowly in one direction. Polishing abrasive is added to the lower grinding chamber. As the rotation continues, when the container reaches the upper position, the polishing abrasive flows back into the abrasive container 1. The polishing of the parts is achieved through the friction between the polishing abrasive and the parts during rotation, as well as the inflow and outflow of the polishing abrasive.

[0037] In this invention, the gap between the filter cartridge 3 and the sand bucket 1 is as small as possible, preferably smaller than the size of the polishing sand, to prevent the polishing sand from getting stuck between the filter cartridge 3 and the sand bucket 1 and causing wear on the equipment.

[0038] This invention, by setting up a built-in sand bucket 1 and an external polishing assembly, can control the presence or absence of polishing sand in each polishing chamber 6, facilitating the placement and removal of parts, realizing automatic recycling of polishing sand, and filtering out parts, making operation convenient.

[0039] This invention enables two grinding methods by controlling the number of sand outlets 2 on the sand bucket 1. When there is only one sand outlet 2, grinding can be performed in a reciprocating manner, resulting in stronger polishing force. When there are two sand outlets 2, cyclic grinding can be achieved, resulting in less grinding force and avoiding excessive shaking of the entire reciprocating device, which could lead to fatigue damage.

[0040] In this invention, each polishing chamber 6 is divided into multiple polishing units 8, which can realize the separate polishing of parts. It is suitable for fine polishing of sharp or thin parts, avoiding the problem of mutual collision between parts and the problem of blind spots caused by thin sheets sticking together.

[0041] In this invention, multiple polishing units 8 are formed by the gap between the filter cartridge 3 and the outer shell 4 through the horizontal partition 5 and the vertical partition 7. The amount of polishing in a single operation is large enough to enable large-scale polishing of parts in batches. In addition, the size of each polishing unit 8 can be customized according to actual production needs, so as to accommodate parts of different sizes.
