Description

Technical Field

[0001] The utility model belongs to the technical field of grinding and polishing, and in particular relates to an automatic polishing machine. Background Art

[0002] A centerless grinder is a type of grinder that does not require the axis of the workpiece to be positioned for grinding. It is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece holder. The grinding wheel is actually responsible for grinding, the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece, and the workpiece holder supports the workpiece during grinding.

[0003] At present, grinding equipment can only grind parts one by one, which greatly reduces production efficiency during processing and production, and lacks the function of simultaneously installing and grinding multiple workpieces. Utility Model Content

[0004] The utility model aims to provide an automatic polishing machine to solve the problem of grinding efficiency in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The automatic polishing machine comprises a processing machine, one side of which is provided with a plurality of connecting sleeves, the connecting sleeves are detachably connected with connecting rods, the connecting rods are equipped with workpieces, and one side of the processing machine is provided with a grinding mechanism fixed below the connecting sleeves;

[0007] The grinding mechanism comprises a workbench, a grinding block is slidably connected to the surface of the workbench, a cylinder is fixedly installed on one side of the workbench, and an output end of the cylinder is connected to one side of the grinding block.

[0008] Furthermore, a fixed cylinder is installed on the surface of the workbench, a positioning rod is slidably connected inside the fixed cylinder, a spring is sleeved inside the positioning rod and a rectangular force block is fixed at one end of the positioning rod.

[0009] Furthermore, a positioning head is provided on the left side of the workpiece, a matching head is provided on the right side of the workpiece, and a hole is provided in the matching head.

[0010] Furthermore, the other end of the positioning rod is conical and cooperates with the hole.

[0011] In the above scheme, the positioning rod is pulled by the rectangular force block, the workpiece is inserted and fixed in the connecting rod, and then the rectangular force block is loosened so that the conical head of the positioning rod and the hole cooperate with each other. The structural design of the conical head can be compatible with some holes of different types and sizes, thereby improving the compatibility of equipment use.

[0012] Furthermore, the surface of the workbench is symmetrically provided with slide grooves, and a protrusion is provided below the grinding block for cooperating with the slide grooves. The cooperation between the slide grooves and the protrusions can stabilize the displacement of the grinding block when the cylinder pushes the grinding block, and prevent the shaking and displacement of the grinding block caused by the contact between the workpiece and the grinding block during grinding.

[0013] Furthermore, the positions of the positioning rod and the connecting sleeve are kept concentric, which can facilitate the positioning rod to be directly positioned and plugged into the hole for mutual cooperation.

[0014] Furthermore, the surface of the grinding block is covered with sponge sand. Its high density and good flexibility enable it to better adapt to various curved and irregular surfaces during grinding. Its grinding ability is better than other abrasives, and it can form new edges and edges in continuous crushing and grading. At the same time, its sand consumption is low and it can be recycled. Stable chemical composition, wear resistance, acid and alkali resistance: this allows the sponge sand to maintain stable performance in various environments and improve the grinding effect.

[0015] The technical solution of the utility model has the following beneficial effects:

[0016] 1. The motor drives the connecting sleeve to rotate, and the product starts to rotate. At the same time, the cylinder pushes the grinding block to perform a cyclic reciprocating motion on the sponge sand for grinding. The centerless grinding principle is adopted to perform fine grinding and polishing on the workpiece until the motor is stopped after the grinding is completed. The cylinder push can simultaneously complete the grinding of multiple workpieces, greatly improving the grinding efficiency.

[0017] 2. This practical device is small and does not take up much space. The operator only needs to place the workpiece to be polished on the corresponding position in advance. Start the motor to rotate the workpiece. The motor completes the polishing work within the set time and stops automatically. Then the object can be unloaded from the workbench.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] refer to Figure 1 The automatic polishing machine includes a processing machine 11, and a plurality of connecting sleeves 12 are installed on one side of the processing machine 11. The plurality of connecting sleeves 12 are linked by a synchronous wheel combination. A motor drive is installed on a group of synchronous wheels to control the rotation of the connecting sleeves 12. The advantage of using synchronous wheels is that each connecting sleeve 12 can be driven to rotate at the same time, and an independently driven motor can also be set for each connecting sleeve 12, so that each connecting sleeve 12 can be driven to rotate separately to achieve independent control;

[0026] The grinding mechanism includes a workbench 18, a grinding block 20 is slidably connected to the surface of the workbench 18, a cylinder 21 is fixedly installed on one side of the workbench 18, and the output end of the cylinder 21 is connected to one side of the grinding block 20. The connecting sleeve 12 is detachably connected with a connecting rod 13, and a detachable connection method is adopted, and the connecting rod 13 can be assembled in the connecting sleeve 12 by nesting bolts and other methods. It is worth noting that the disassembly method can facilitate the staff to replace other types of connecting rods 13, which are not limited to the figure, so that different connecting rods 13 can be matched with different workpieces 14;

[0027] The connecting rod 13 is equipped with a workpiece 14. Multiple workpieces 14 are installed on multiple connecting rods 13 for simultaneous grinding. The workpiece 14 installed on the connecting rod 13 will rotate along with the rotation of the connecting sleeve 12. When the cylinder 21 pushes the grinding block 20 to move, the grinding block 20 will pass under the workpiece 14. The rotating workpiece 14 will produce friction with the grinding block 20 to complete the grinding. The cylinder 21 can push and grind multiple workpieces 14 synchronously at the same time, greatly improving the grinding efficiency. A grinding mechanism is fixed on one side of the processing machine tool 11 below the connecting sleeve 12.

[0028] The surface of the grinding block 20 is covered with sponge sand. It has high density and good flexibility, so it can better adapt to various curved surfaces and irregular surfaces during grinding. Its grinding ability is better than other abrasives, and it can form new edges and edges in continuous crushing and grading. At the same time, its sand consumption is low and it can be recycled. Stable chemical composition, wear resistance, acid and alkali resistance: this allows the sponge sand to maintain stable performance in various environments and improve the grinding effect.

[0029] Further references Figure 2 and Figure 3 A fixed cylinder 22 is installed on the surface of the workbench 18, and a positioning rod 23 is slidably connected in the fixed cylinder 22. A spring is sleeved in the positioning rod 23 and is fixed to one end of the positioning rod 23. A rectangular force block 24 is fixed to one end of the positioning rod 23, and the other end of the positioning rod 23 is conical and cooperates with the hole 16. A positioning head 17 is provided on the left side of the workpiece 14. The positioning head 17 adopts a hexagonal structure, and the positioning head 17 is used to cooperate and be connected inside the connecting rod 13. A hexagonal groove that cooperates with its positioning head 17 is provided inside the connecting rod 13. This method adopts a nesting method. Through nesting, it can be more convenient for the staff to take out the workpiece 14 after grinding is completed. A matching head 15 is provided on the right side of the workpiece 14, and a hole 16 is provided in the matching head 15.

[0030] In the above scheme, when installing the workpiece 14, the positioning rod 23 is pulled by the rectangular force block 24, and the workpiece is inserted and fixed in the connecting rod 13. Then, the rectangular force block 24 is loosened so that the conical head of the positioning rod 23 cooperates with the hole 16. The structural design of the conical head can be compatible with some holes 16 of different types and sizes, thereby improving the compatibility of the equipment. The position of the positioning rod 23 and the connecting sleeve 12 remains concentric, which can facilitate the positioning rod 23 to be directly positioned and plugged in to cooperate with the hole 16.

[0031] Embodiment 2:

[0032] refer to Figure 1 The surface of the workbench 18 is symmetrically provided with a slide groove 19, and a protrusion for cooperating with the slide groove 19 is provided below the grinding block 20. The cooperation between the slide groove 19 and the protrusion can stabilize the displacement of the grinding block 20 when the cylinder 21 pushes the grinding block 20, and prevent the shaking and deviation of the grinding block 20 caused by the grinding contact between the workpiece 14 and the grinding block 20.

[0033] In the above embodiment:

[0034] When in use, the connecting rod 13 is installed in the connecting sleeve 12, the positioning rod 23 is pulled backward, the workpiece 14 is placed in the connecting rod 13, the positioning rod 23 is loosened to make it support the center of the product, and the motor is started. The motor drives the connecting sleeve 12 to rotate, the product starts to rotate, and the cylinder pushes the grinding block 20 to perform a circular reciprocating motion on the sponge sand for grinding. The principle of centerless grinding is adopted to finely grind and polish the workpiece until the grinding is completed and the motor is stopped.

[0035] This practical device is small and does not take up too much space. The operator only needs to place the workpiece 14 to be polished on the corresponding position in advance. Start the motor to rotate the workpiece. The motor completes the polishing work within the set time and stops automatically, and then the object can be unloaded from the workbench. It is worth noting that before the motor starts polishing, the distance between the sponge sand and the product needs to be adjusted. In order to achieve the best contact effect and throw the best effect. The position adjustment of the grinding block 20 can be achieved by installing a lifting cylinder under the workbench 18. At this time, the workbench 18 is slidably installed on the processing machine 11, or by replacing the grinding blocks 20 of different thicknesses, so as to achieve the best contact effect.
