Description

Technical Field

[0001] This utility model relates to the field of sandblasting technology, and in particular to a multi-axis linkage device for sandblasting. Background Technology

[0002] Sandblasting is a process that uses high-speed abrasive jets to impact and cut the surface of a workpiece. It typically uses compressed air as a power source to propel abrasive materials (such as quartz sand, corundum, etc.) through nozzles at high speed onto the workpiece surface to remove oxide scale, dirt, grease, paint, etc., thereby improving coating adhesion and enhancing the mechanical properties of the workpiece.

[0003] Currently, the sandblasting methods for small products and large products are roughly the same. However, because small products occupy a small area, the number of small products in a large space is small when sandblasting them, resulting in low sandblasting efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-axis linkage device for sandblasting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A third fixing plate is detachably connected to the top of the fourth fixing plate via bolts. A drive shaft and multiple driven shafts are rotatably connected between the third and fourth fixing plates via bearings. A first fixing plate is detachably connected to the top of the second fixing plate via bolts. Multiple connectors are provided between the first and second fixing plates. The drive shaft and multiple driven shafts are respectively fixed to the multiple connectors. A motor is fixedly connected to the upper surface of the base. One end of the motor's output shaft is fixed to the drive shaft. Gears are keyed to the outer sides of the drive shaft and multiple driven shafts, with adjacent gears meshing. One end of each connector has two first mounting holes and two second mounting holes. The product body is inserted into the first mounting holes.

[0012] As a further embodiment of this utility model, a second protective cover is fixedly connected to the top of the first fixing plate, and the second protective cover is in contact with the first protective cover.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4 A multi-axis linkage sandblasting device includes a base 1 and a product body 20. A second fixing plate 5 and a fourth fixing plate 12 are bolted to the upper surface of the base 1. A third fixing plate 7 is detachably connected to the top of the fourth fixing plate 12 by bolts. A drive shaft 8 and multiple driven shafts 10 are rotatably connected between the third fixing plate 7 and the fourth fixing plate 12 via bearings. A first fixing plate 4 is detachably connected to the top of the second fixing plate 5 by bolts. Multiple connectors 9 are provided between the first fixing plate 4 and the second fixing plate 5. The drive shaft 8 and the multiple driven shafts 10 are respectively fixed to the multiple connectors 9. A motor 6 is bolted to the upper surface of the base 1. One end of the output shaft of the motor 6 is fixed to the drive shaft 8. Gears 11 are keyed to the outer sides of the drive shaft 8 and the multiple driven shafts 10. Two adjacent gears 11 mesh with each other. One end of the connector 9 has two first mounting holes 15 and two second mounting holes 19. The product body 20 is inserted into the first mounting hole 15. The connector 9 is equipped with a pressing component to help fix the product body 20. The product body 20 is inserted into the first mounting hole 15 or the second mounting hole 19 on the connector 9. Then the motor 6 is started. The motor 6 will drive the drive shaft 8 to rotate. During the rotation of the drive shaft 8, it will drive the remaining driven shaft 10 to rotate synchronously through the gear 11. The drive shaft 8 and the driven shaft 10 will drive the connector 9 to rotate synchronously. The connector 9 will drive the product body 20 to rotate synchronously, so that multiple small products can be sandblasted evenly at the same time, saving space, saving costs, and improving sandblasting efficiency.

[0023] In this utility model, the extrusion assembly includes multiple sliding holes 17, all of which are opened in the connector 9. The multiple sliding holes 17 are respectively connected to the first mounting hole 15 and the second mounting hole 19. Extrusion blocks 16 are slidably connected in each of the multiple sliding holes 17, and springs 18 are provided in each of the multiple sliding holes 17. The two ends of the springs 18 are respectively fixed to the extrusion blocks 16 and the connector 9. During the rotation of the connector 9, under the action of centrifugal force, the extrusion blocks 16 will generate a force to move outward from the sliding holes 17. At this time, the extrusion blocks 16 will extrude the product body 20, thereby assisting in fixing the product and making the product stable for installation, improving the stability of sandblasting the product. The springs 18 will cause the extrusion blocks 16 to automatically reset after moving.

[0024] The bottom of the first fixing plate 4 and the third fixing plate 7 are each welded with two positioning pins 13. The top of the second fixing plate 5 and the fourth fixing plate 12 are each provided with two insertion holes 14, and the positioning pins 13 are inserted into the insertion holes 14. Through the cooperation of the positioning pins 13 and the insertion holes 14, the first fixing plate 4 and the second fixing plate 5 can be positioned and connected, and the third fixing plate 7 and the fourth fixing plate 12 can be positioned and connected, thereby facilitating the installation of the first fixing plate 4 and the third fixing plate 7. The drive shaft 8 is located in the middle of multiple driven shafts 10. The top of the third fixing plate 7 is fixed with a first protective cover 2 by bolts, and the top of the first fixing plate 4 is fixed with a second protective cover 3 by bolts. The second protective cover 3 fits against the first protective cover 2. The first protective cover 2 and the second protective cover 3 can protect the motor 6, the drive shaft 8, the driven shafts 10 and the gears 11.

[0025] Working principle: When needed, insert the product body 20 into the first mounting hole 15 or the second mounting hole 19 on the connector 9, then start the motor 6. The motor 6 will drive the drive shaft 8 to rotate. During the rotation of the drive shaft 8, it will drive the remaining driven shaft 10 to rotate synchronously through the gear 11. The drive shaft 8 and the driven shaft 10 will drive the connector 9 to rotate synchronously. The connector 9 will drive the product body 20 to rotate synchronously, thereby simultaneously and uniformly sandblasting multiple small products, saving space, saving costs, and improving sandblasting efficiency. During the rotation of the connector 9, under the action of centrifugal force, the extrusion block 16 will generate a force to move outward from the sliding hole 17. At this time, the extrusion block 16 will squeeze the product body 20, thereby assisting in fixing the product and making the product stably installed, improving the stability of sandblasting.

[0026] Finally, it should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
