Description

Technical Field

[0001] This utility model relates to the field of sandblasting tooling technology, and more specifically, to a sandblasting tooling device for workpieces. Background Technology

[0002] Sandblasting is a process that uses the impact of high-speed sand jets to clean and roughen the surface of a substrate. For workpieces that need to be coated or bonded, sandblasting can remove rust, scale and other contaminants from the workpiece surface and create a rough surface, which greatly improves the bonding strength between the workpiece and the coating or plating, making the bonded parts more firmly bonded and of better quality.

[0003] In practical applications, the demand for abrasives is very high when performing continuous sandblasting operations on a large number of tubular workpieces. The frequency and amount of abrasive procurement are also very high. However, some of the abrasives used still maintain a large volume, which will reduce the efficiency of sandblasting and increase the cost of use during long-term sandblasting. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sandblasting fixture for workpieces to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sandblasting fixture for a workpiece includes a housing with two openings on its inner side. Two guide shells are fixedly connected to the outer side of the housing. Support rods are slidably connected to the inner sides of the guide shells. Pins are inserted into the inner sides of the guide shells and support rods. A base frame is fixedly connected to the top of the support rods. Two rotating rollers are rotatably connected to the top of the base frame. Two supports are fixedly connected to the inner side of the housing, with their outer sides slidably connected to the inner side of the base frame. A circulation mechanism is provided at the bottom of the housing. The circulation mechanism includes a bottom shell, the top of which is fixedly connected to the lower surface of the housing. A shell cover is hinged to one side of the bottom shell. A bottom frame is provided inside the shell cover, and multiple sieve holes are opened inside the bottom frame. Two... The guide frame includes a lead screw rotatably connected to the inner side of one guide frame and a guide rod fixedly connected to the inner side of the other guide frame. A transmission frame is slidably connected to the inner side of the guide frame, with one end of the transmission frame threaded to the outer side of the lead screw and the other end slidably connected to the outer side of the guide rod. An opening for cleaning sandblasting is provided on one side of the bottom shell. A servo motor is fixedly connected to one end of one guide frame, and the output end of the servo motor is fixedly connected to one end of the lead screw. Support rods are provided on the inner sides of both guide frames. Multiple actuating rods are rotatably connected to the outer side of the transmission frame, with two limit blocks fixedly connected to the outer side of each actuating rod. Multiple positioning blocks are fixedly connected to the outer side of the transmission frame. Two sandblasting mechanisms are provided on the inner side of the outer shell.

[0006] By adopting the above technical solution, the abrasive material gathered inside the bottom frame is swept by the reciprocating scraping motion of the transmission frame and the actuating rod, which promotes the separation of large and small abrasive particles for recycling.

[0007] As a further description of the above technical solution: the sandblasting mechanism includes two fixed rods, the outer side of the fixed rods is fixedly connected to the inner side of the housing, and two sandblasting conveying pipes are fixedly connected to the inner side of the fixed rods. One end of the sandblasting conveying pipe is connected to an external sandblasting device, and the other end of the sandblasting conveying pipe is fixedly connected to a spray pipe. The outer side of the spray pipe is hinged to the outer side of the fixed rod, and an electric cylinder is hinged to the bottom of the spray pipe. The end of the electric cylinder is hinged to the inner side of the fixed rod.

[0008] By adopting the above technical solution, a spray nozzle with an adjustable blasting angle can maintain a good blasting effect on the surface of tubular workpieces of different diameters.

[0009] The technical effects and advantages of this utility model are as follows: 1. By setting up a circulation mechanism, compared with the existing technology, the abrasive aggregate is stirred by the transmission frame and the actuating rod, which promotes the screening of the abrasive aggregate and recovers reusable large abrasive particles by screening, while removing small particles and dust that have been crushed and pulverized and do not meet the process requirements. This can reduce the amount of new abrasive used, directly save production costs, and reduce the cost of industrial waste disposal. 2. By setting up a sandblasting mechanism, compared with the existing technology, the sandblasting angle of the adjustable nozzle can be used to make the sandblasting more suitable at the angle to contact the surface of the tubular workpiece, thereby improving the sandblasting processing accuracy of different tubular workpieces and increasing the utilization rate of abrasive.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The embodiments disclosed in this application are as follows: Figures 1-6 The sandblasting fixture shown includes a housing 1 with two openings 2 on its inner side. Two guide shells 3 are fixedly connected to the outer side of the housing 1. Support rods 4 are slidably connected to the inner sides of the guide shells 3. Pins 5 are inserted into the inner sides of the guide shells 3 and support rods 4. A base frame 6 is fixedly connected to the top of the support rods 4. Two rotating rollers 7 are rotatably connected to the top of the base frame 6. Two supports 8 are fixedly connected to the inner side of the housing 1, and the outer sides of the supports 8 are slidably connected to the inner side of the base frame 6. The height of the multiple rotating rollers 7 can be adjusted to accommodate tubular workpieces of different diameters. A circulation mechanism is provided at the bottom of the housing 1. The circulation mechanism includes a bottom shell 9, the top of which is fixedly connected to the lower surface of the housing 1. A cover 10 is hinged to one side of the bottom shell 9. A bottom frame 11 is provided inside the cover 10, and multiple sieve holes 12 are opened inside the bottom frame 11. The inner side of the housing 1 is fixedly connected to the bottom surface of the housing 1. Two guide frames 13 are connected. A lead screw 14 is rotatably connected to the inner side of one guide frame 13, and a guide rod 15 is fixedly connected to the inner side of the other guide frame 13. A transmission frame 17 is slidably connected to the inner side of the guide frame 13. One end of the transmission frame 17 is threaded to the outer side of the lead screw 14, and the other end of the transmission frame 17 is slidably connected to the outer side of the guide rod 15. An opening for cleaning sandblasting is provided on one side of the bottom shell 9. A servo motor 16 is fixedly connected to one end of one guide frame 13. The output end of the servo motor 16 is fixedly connected to one end of the lead screw 14. Support rods are provided inside the two guide frames 13. Multiple actuating rods 18 are rotatably connected to the outer side of the transmission frame 17. Two limit blocks 20 are fixedly connected to the outer side of the actuating rods 18. Multiple positioning blocks 19 are fixedly connected to the outer side of the transmission frame 17. Two sandblasting mechanisms are provided inside the outer shell 1. Larger abrasive particles are left inside the bottom frame 11 by multiple sieve holes 12, so that the abrasive particles can be recycled to a certain extent. Combined with the reciprocating motion of the transmission frame 17 and multiple actuating rods 18, fine abrasive particles and dust are forced to pass through the sieve holes 12 and enter the interior of the bottom shell 9 for collection.

[0019] Reference Figure 1 and Figure 5 As shown, the sandblasting mechanism includes two fixed rods 21. The outer side of the fixed rods 21 is fixedly connected to the inner side of the outer casing 1. Two sandblasting conveying pipes 22 are fixedly connected to the inner side of the fixed rods 21. One end of the sandblasting conveying pipe 22 is connected to an external sandblasting device, and the other end of the sandblasting conveying pipe 22 is fixedly connected to a spray pipe 23. The outer side of the spray pipe 23 is hinged to the outer side of the fixed rods 21. An electric cylinder 24 is hinged to the bottom of the spray pipe 23. The end of the electric cylinder 24 is hinged to the inner side of the fixed rods 21. The corresponding electric cylinder 24 is used to push the spray pipe 23 to deflect, so that the sandblasting angle of the spray nozzle of the spray pipe 23 to the tubular workpiece is adjusted, so that the abrasive can better sandblast the tubular workpiece.

[0020] The working principle of this utility model is as follows: When cleaning a tubular workpiece, the height of the base frame 6 and the rotating roller 7 is first adjusted according to the diameter of the tubular workpiece. The pin 5 is pulled out from the inside of the guide shell 3 and the support rod 4, and the base frame 6 is pushed to slide up and down on the outside of the bracket 8. Then the pin 5 is reinserted into the guide shell 3 and the support rod 4, so that the two base frames 6 and the two rotatable rotating rollers 7 on top can roll and support the tubular workpiece, and keep the center of the tubular workpiece at a relatively level height with the two fixed rods 21. Then, the external sandblasting equipment is started to sandblast the surface of the tubular workpiece through the sandblasting conveying pipe 22 and the spray pipe 23. At the same time, the electric cylinder 24 corresponding to the bottom of the spray pipe 23 is used to extend and deflect the spray pipe 23, so that the sand outlet end of the spray pipe 23 can be adjusted to maintain the sandblasting process on the tubular workpiece. After sandblasting, the abrasive will fall down to the inside of the base frame 11 and accumulate. Then, the servo motor 16 is started to drive the lead screw 14 to drive the transmission frame 1. One end of 7 is threaded and guided by guide rod 15 to slide the transmission frame 17, allowing the transmission frame 17 to slide back and forth inside the two guide frames 13. At the same time, the transmission frame 17 drives multiple actuating rods 18 to drive the transmission, and cooperates with multiple positioning blocks 19 on the outside of the transmission frame 17 to push the limiting block 20 on the outside of the actuating rods 18. This allows the multiple actuating rods 18 to move the abrasive gathered inside the bottom frame 11, causing smaller abrasive particles inside the bottom frame 11 to pass through the sieve hole 12 and fall into the inside of the bottom shell 9. When removing larger abrasive particles, the shell cover 10 is opened first, and then the bottom frame 11 is pulled out from one side of the bottom shell 9 for cleaning and collection. Afterwards, the transmission frame 17 drives the actuating rods 18 to move to the support rod side inside the two guide frames 13, so that the multiple actuating rods 18 are deflected under the support of the transmission frame 17, making it easy to reinsert the bottom frame 11 into the bottom shell 9, thus completing the collection and reuse of larger tubular workpiece particles.
