Description

Technical Field

[0001] This invention belongs to the field of shot blasting machine technology, and specifically relates to a suspended sealing conveying device for a shot blasting machine. Background Technology

[0002] Currently, shot blasting machines typically have multiple hooks on their overhead conveyor. When the machine starts working, the hooks load the material at the loading station, then travel along the track and enter the shot blasting chamber for shot blasting. Since there are usually two or more hooks accumulating inside the shot blasting chamber, there will be a large gap at the joint of each pair of hooks. When the workpiece is shot blasted, the shot will splash out from the gap, causing a lot of inconvenience to the user. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a suspended sealing conveying device for a shot blasting machine.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a suspended sealing conveying device for a shot blasting machine, comprising two linear guide rails, with an arc-shaped guide rail installed between both ends of the two linear guide rails, and multiple traveling mechanisms cooperating on the linear guide rails. A connecting column is installed below each of the multiple traveling mechanisms via a connecting plate, and a hook is installed below the connecting column for suspending the workpiece to be processed. A sealing plate is installed on the outer periphery of the connecting column, and the gap between the sealing plates below adjacent traveling mechanisms is smaller than the diameter of the shot required by the shot blasting machine. Two support assemblies are installed between the two linear guide rails, and a stopper is installed on the side of each of the two support assemblies.

[0005] Preferably, a connecting plate two is installed above the end of the sealing plate away from the forward direction of the walking mechanism, and a sealing element one is installed above the connecting plate two. A hook is installed at the end of the sealing element one away from the connecting plate two, and the hook is oriented towards the direction close to the connecting plate two. The length of the sealing element one is greater than the length of the connecting plate two.

[0006] Preferably, each of the multiple walking mechanisms includes two walking components and a fixing component. Both walking components cooperate with a linear guide rail and an arc-shaped guide rail. The fixing component includes a connector and a clamping component. The connector is installed on the side of the walking component near the seal, and the clamping component is installed on the side of the walking component away from the seal. The connector and the clamping component cooperate. The lower part of each of the two walking components is detachably connected to a connecting plate. Two connecting posts are installed between the connecting plate and the seal.

[0007] Preferably, the clamping component includes a fixed plate and a bidirectional lead screw. The fixed plate is installed on the side of the traveling component away from the seal. Support plates are installed at both ends of the fixed plate. The bidirectional lead screw passes through the two support plates and is fitted with two clamping plates. A connector is located between the two clamping plates. A drive motor is installed on the side of the support plate, and the output end of the drive motor is detachably connected to the end of the bidirectional lead screw. A counterweight is installed on the side of the other support plate. A sliding groove is formed on the side of the fixed plate, and both clamping plates are slidably connected to the sliding groove.

[0008] Preferably, connecting side plates are installed on both sides of the fixing plate, and a fixing platform is installed between the two connecting side plates. A cylinder is installed on the side of the fixing platform away from the fixing plate. A protrusion is detachably connected to the piston rod end of the cylinder. A groove is provided on the side of the connector near the seal, and the protrusion engages with the groove. The side of the connector near the seal is a slope, and the side of the protrusion near the cylinder is a slope. The slopes are parallel.

[0009] Preferably, each of the multiple walking components is equipped with an inclined plate 1 above it, and an inclined plate 2 is installed at the end of the inclined plate 1. A support column 2 is installed between the inclined plate 1 and the inclined plate 2. A sliding plate 1 is installed below the support column 2. A connecting plate 4 is installed between the sliding plate 1 and the inclined plate 1. A sliding groove 2 is provided above the two linear guide rails, and an arc-shaped sliding groove is provided above the arc-shaped guide rail. The sliding plate 1 is slidably connected to both the sliding groove 2 and the arc-shaped sliding groove.

[0010] Preferably, the stopper includes a support platform two and a cylinder three. The support platform two is installed on the side of the bracket assembly, and the cylinder three is installed above the support platform two. The piston rod end of the cylinder three is detachably connected to a side U-shaped frame one. Two rotating shafts pass through the side U-shaped frame one. Connecting rod two is installed obliquely on the outer periphery of both rotating shafts. Connecting rod one is connected to the end of connecting rod two away from the cylinder three. A clamping stop plate is connected to the end of connecting rod one. The two clamping stop plates are arranged opposite to each other and cooperate with the support column two. An arc-shaped connecting rod is installed at the end of connecting rod two near the cylinder three. A cylinder four is hinged between the ends of the two arc-shaped connecting rods.

[0011] Preferably, a fixing rod is installed on the inner side of each of the two connecting rods 2, a disk 1 is installed inside the side U-shaped frame 1, a limiting post is installed on the side of the disk 1 near the cylinder 3, a sliding sleeve is slidably connected to the outer periphery of the limiting post, and a connecting rod 3 is hinged to the end of the fixing rod, and the end of the connecting rod 3 is hinged to the sliding sleeve.

[0012] Preferably, a support platform is installed on the side of the bracket assembly away from the support platform two, and a cylinder two is installed on the side of the support platform one. A stop plate is detachably connected to the piston rod end of the cylinder two, and the stop plate cooperates with the support column two.

[0013] Preferably, the system also includes a numerical control system, and all of the walking mechanisms and stops are communicatively connected to the numerical control system.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows: (1) There is a large gap at the joint of the two hooks of the existing suspended conveyor device. However, the present invention installs a sealing plate on the outer periphery of the connecting column one, so that the gap between the corresponding sealing plates under the adjacent walking mechanism is smaller than the diameter of the shot required by the shot blasting machine, that is, the length of the sealing plate is extended. This eliminates the phenomenon that the shot will splash out from the gap when the workpiece is shot blasted, and blocks the shot leakage path from the source, avoiding shot waste and pollution of the external environment of the equipment. (2) Since the gap between adjacent sealing plates is small, continuous passage is not possible when passing through the arc guide rail. The present invention has stoppers installed on the sides of both bracket assemblies, so that the workpiece to be processed can be carried through the arc guide rail by a single hook. (3) The sealing element one installed at the end of the sealing plate through the connecting plate two has a hook at the end facing the connecting plate two and its upper length exceeds the connecting plate two, further filling the sealing gap. The double sealing design greatly improves the sealing reliability, ensuring that the shot always acts on the workpiece during shot blasting and ensuring the processing quality. (4) The drive motor drives the bidirectional lead screw to clamp the clamping plate and the connecting piece, and the cylinder pushes the protrusion into the groove of the connecting piece. The double reinforcement ensures the stability of synchronous movement. (5) The stopper is driven by cylinder three and cylinder four in a coordinated manner, which drives the clamping stop plate to clamp the support column two of the walking component. At the same time, the anti-reverse plate assists in limiting from the rear, so as to achieve stable stopping of the walking mechanism. With the auxiliary structure of the sliding sleeve sliding along the limiting column, the smoothness of the stopping action is further improved. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1 The following is in conjunction with the appendix Figure 1 and attached Figure 3 To further describe the present invention, a suspended sealing conveying device for a shot blasting machine, such as... Figure 1As shown, the system includes two linear guide rails 1, with arc-shaped guide rails 2 installed between both ends of the two linear guide rails 1. Multiple traveling mechanisms 3 are fitted on the linear guide rails 1. Connecting columns 5 are installed below each of the multiple traveling mechanisms 3 via connecting plates 4. Hooks 6 are installed below the connecting columns 5 for suspending the workpiece to be processed. Sealing plates 8 are installed on the outer periphery of the connecting columns 5. The gap between the corresponding sealing plates 8 below adjacent traveling mechanisms 3 is smaller than the diameter of the shot required by the shot blasting machine. Two support assemblies are installed between the two linear guide rails 1, and stoppers are installed on the sides of both support assemblies.

[0020] like Figure 1 and Figure 3 As shown, a connecting plate 2 18 is installed above the end of the sealing plate 8 away from the forward direction of the walking mechanism 3. A sealing element 19 is installed above the connecting plate 2 18. A hook is installed at the end of the sealing element 19 away from the connecting plate 2 18. The hook faces the direction close to the connecting plate 2 18. The length of the sealing element 19 is greater than the length of the connecting plate 2 18.

[0021] It also includes a CNC system, and multiple traveling mechanisms 3 and stop devices are all connected to the CNC system.

[0022] In this embodiment, the bracket assembly includes two connecting plates 20, which are respectively installed above two linear guide rails 1. A horizontal plate 21 is installed between the two connecting plates 20, and multiple support columns 22 are installed below the horizontal plate 21.

[0023] In this embodiment, all of the multiple walking mechanisms 3 are existing walking mechanisms, capable of rolling along the linear guide rail 1 and the arc-shaped guide rail 2.

[0024] In this embodiment, the two stops are located on the side of the end of the linear guide 1 near the end of the arc-shaped guide 2 in the forward direction of the traveling mechanism 3.

[0025] In this embodiment, the stopper is an existing stopper.

[0026] In this embodiment, one of the linear guide rails 1 is located inside the shot blasting machine.

[0027] The working principle of this embodiment is as follows: The workpiece to be processed is hung on hook 6. The CNC system sends a start signal, and multiple traveling mechanisms 3 drive the workpiece to move along the linear guide rail 1. After one of the traveling mechanisms 3 in the forward direction passes the stop, the stop opens, blocking the following traveling mechanism 3, causing the traveling mechanism 3 to stop on the linear guide rail 1. The preceding traveling mechanism 3 then passes through the arc-shaped guide rail 2 first. This is because the gap between the sealing plates 8 below the multiple traveling mechanisms 3 is small, and a collision would occur if they all passed through the arc-shaped guide rail 2. The preceding traveling mechanism 3 passes through the arc-shaped guide rail 2 first, and then moves a suitable distance along the linear guide rail 1. At this point, the forward traveling mechanism 3 stops, and the stopper returns to its initial position. The rear traveling mechanism 3, via the arc-shaped guide rail 2, maintains the initial gap distance with the sealing plate 8 of the forward traveling mechanism 3. Then, the two traveling mechanisms 3 enter the shot blasting machine together along the linear guide rail 1. The shot blasting machine processes the workpiece to be processed on the hook 6. The sealing plates 8 installed on the outer periphery of the connecting column 5 have gaps between adjacent ones that are smaller than the diameter of the shot required by the shot blasting machine, which can prevent the shot from leaking out of the gaps. After processing is completed, the operation is repeated. Multiple traveling mechanisms 3 move the processed workpiece to the initial position for unloading and the next loading.

[0028] In this embodiment, the sealing element 19 installed by the connecting plate 2 18 has its end hook facing towards the connecting plate 2 18, and the upper length of the sealing element 19 is greater than that of the connecting plate 2 18, which further enhances the sealing effect and prevents the leakage of the projectile.

[0029] Example 2 The main difference between this embodiment and Embodiment 1 is: Figure 1 and Figure 2 As shown, each of the multiple walking mechanisms 3 includes two walking components and a fixed component. Both walking components cooperate with the linear guide rail 1 and the arc guide rail 2. The fixed component includes a connector 9 and a clamping component. The connector 9 is installed on the side of the walking component near the seal 19, and the clamping component is installed on the side of the walking component away from the seal 19. The connector 9 and the clamping component cooperate. The lower part of both walking components is detachably connected to the connecting plate 4. Two connecting posts 7 are installed between the connecting plate 4 and the sealing plate 8.

[0030] like Figure 1 and Figure 2As shown, the clamping component includes a fixed plate 10 and a bidirectional lead screw 12. The fixed plate 10 is installed on the side of the traveling assembly away from the seal 19. Support plates 11 are installed at both ends of the fixed plate 10. The bidirectional lead screw 12 passes through the two support plates 11. Two clamping plates 15 are fitted on the bidirectional lead screw 12. The connector 9 is located between the two clamping plates 15. A drive motor 13 is installed on the side of the support plate 11. The output end of the drive motor 13 is detachably connected to the end of the bidirectional lead screw 12. A counterweight is installed on the side of the other support plate 11. A sliding groove is opened on the side of the fixed plate 10. Both clamping plates 15 are slidably connected to the sliding groove.

[0031] like Figure 1 and Figure 2 As shown, connecting side plates 14 are installed on both sides of the fixed plate 10, and a fixed platform is installed between the two connecting side plates 14. A cylinder 16 is installed on the side of the fixed platform away from the fixed plate 10. A protrusion 17 is detachably connected to the end of the piston rod of the cylinder 16. A groove 1 is provided on the side of the connector 9 near the seal 19, and the protrusion 17 cooperates with the groove 1. The side of the connector 9 near the seal 19 is a slope 1, and the side of the protrusion 17 near the cylinder 16 is a slope 2. Slope 1 and slope 2 are parallel.

[0032] In this embodiment, the walking component is an existing walking component.

[0033] In this embodiment, a counterweight block 2 is also installed on the side of the walking component near the seal 19 to balance the other walking component.

[0034] In this embodiment, both the drive motor 13 and the cylinder 16 are communicatively connected to the CNC system.

[0035] In this embodiment, the line connecting the two connecting side plates 14 is perpendicular to the line connecting the two support plates 11.

[0036] Based on Example 1, the principle of the two walking mechanisms 3 moving synchronously along the linear guide rail 1 is as follows: When the two walking mechanisms 3 need to move synchronously (i.e. before entering the shot blasting machine), after the rear walking mechanism 3 moves to the appropriate position, the CNC system controls the drive motor 13 to start, driving the bidirectional lead screw 12 to rotate, so that the two clamping plates 15 slide along the slide groove of the fixed plate 10, clamping and fixing the connecting piece 9 of the front walking mechanism 3. Then, the drive motor 13 is turned off, the cylinder 16 is turned on, so that the protrusion 17 is inserted into the groove of the connecting piece 9, and the inclined surface 2 of the protrusion 17 is in contact with the inclined surface 1 of the connecting piece 9. Then, the cylinder 16 is turned off, further reinforcing the connection between the two walking mechanisms 3.

[0037] When the two walking mechanisms 3 need to be disassembled (i.e., after exiting the shot blasting machine and before entering the arc-shaped guide rail 2), cylinder 16 is activated to disengage protrusion 17 from groove 1. Cylinder 16 is then closed, drive motor 13 is activated, and the two clamping plates 15 disengage from connector 9. Drive motor 13 is then closed, and the forward walking mechanism 3 enters the arc-shaped guide rail 2, while the rear walking mechanism 3 is blocked by the stopper.

[0038] Example 3 The main difference between this embodiment and embodiments 1 and 2 is: As Figure 4 and Figure 5 As shown, inclined plate 1 23 is installed above multiple walking components, inclined plate 24 is installed at the end of inclined plate 1 23, support column 27 is installed between inclined plate 1 23 and inclined plate 24, sliding plate 1 26 is installed below support column 27, connecting plate 4 25 is installed between sliding plate 1 26 and inclined plate 1 23, sliding groove 2 is opened above the two linear guide rails 1, and arc-shaped sliding groove is opened above the arc-shaped guide rail 2. Sliding plate 1 26 is slidably connected to sliding groove 2 and arc-shaped sliding groove.

[0039] like Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown, the stopper includes a second support platform 31 and a third cylinder 32. The second support platform 31 is mounted on the side of the bracket assembly, and the third cylinder 32 is mounted above the second support platform 31. The piston rod end of the third cylinder 32 is detachably connected to a side U-shaped frame 33. Two rotating shafts 44 pass through the side U-shaped frame 33. Connecting rods 36 are obliquely mounted on the outer periphery of the two rotating shafts 44. Connecting rods 35 are connected to the end of connecting rods 36 away from the third cylinder 32. Clamping stop plates 34 are connected to the end of connecting rods 35. The two clamping stop plates 34 are arranged opposite each other and cooperate with the second support column 27. An arc-shaped connecting rod 37 is installed on the end of connecting rod 36 near the third cylinder 32. A fourth cylinder 38 is hinged between the ends of the two arc-shaped connecting rods 37.

[0040] like Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown, a fixing rod 43 is installed on the inner side of each of the two connecting rods 36. A disc 39 is installed inside the side U-shaped frame 33. A limiting post 40 is installed on the side of the disc 39 near the cylinder 32. A sliding sleeve 41 is slidably connected to the outer periphery of the limiting post 40. A connecting rod 42 is hinged to the end of the fixing rod 43. The end of the connecting rod 42 is hinged to the sliding sleeve 41.

[0041] like Figure 4 and Figure 6As shown, a support platform 28 is installed on the side of the bracket assembly away from the support platform 2 31. A cylinder 29 is installed on the side of the support platform 28. A stop plate 30 is detachably connected to the piston rod end of the cylinder 29. The stop plate 30 cooperates with the support column 27.

[0042] In this embodiment, the tilt angle of inclined plate 23 and the tilt angle of inclined plate 24 are symmetrical, and the end of inclined plate 24 and the side of the slide near inclined plate 24 are on the same vertical plane.

[0043] In this embodiment, the connecting plate 3 20 is installed above the inner side of the linear guide rail 1 and the slide groove 2.

[0044] In this embodiment, cylinders 32, 38, and 29 are all connected to the CNC system.

[0045] In this embodiment, the fixing rod 43 and the connecting rod 36 are installed at an angle.

[0046] The working principle of this embodiment is as follows: Based on embodiment 2, after exiting the shot blasting machine, the forward walking mechanism 3 enters the arc-shaped guide rail 2, and cylinders 32 and 29 are activated. Cylinder 32 pushes the side U-shaped frame 33 to move away from cylinder 32. After moving to a suitable position, cylinder 32 is closed, and cylinder 29 pushes the stop plate 30 to move away from cylinder 29 until the stop plate 30 is behind the support column 27 above the walking assembly behind the walking mechanism 3. Then, cylinder 4 is activated, and cylinder 4 drives the two connecting rods 36 to rotate around the rotating shaft 44. Through connecting rod 35, the two clamping stop plates 34 approach and clamp the support column 27. During this period, the fixed rod 43 drives the connecting rod 42 to pull the sliding sleeve 41 to slide along the limiting column 40, which helps to stabilize the movement of connecting rod 36, thereby stopping the rear walking mechanism 3 on the linear guide rail 1.

[0047] Before the rear walking mechanism 3 is opened to enter the arc-shaped guide rail 2, cylinder 4 38 needs to be opened first to disengage the two clamping stop plates 34 from the support column 27, then cylinder 3 32 is opened to return the side U-shaped frame 33 to its initial position, then cylinder 2 29 is opened to return the anti-reverse plate 30 to its initial position, and then the two walking components of the rear walking mechanism 3 are opened to enter the arc-shaped guide rail 2.

[0048] In this invention, the above process can be automatically controlled by a numerical control system.

[0049] In this invention, the above process can be adjusted according to the on-site conditions.

[0050] As a technical solution of this invention, the provided hardware configuration is merely for facilitating the implementation of specific braking control based on the hardware facilities. How to specifically implement braking control and the braking control method are not the technical problems to be solved or the objects of protection of this invention. Furthermore, the communication methods between the devices all employ existing communication methods and are not the inventive point of this invention.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields.
