Hanging shot blasting machine

Abstract

This utility model proposes a suspended shot blasting machine, comprising: a device housing, a support, a moving mechanism, and a hanging mechanism. The device housing contains a shot blasting unit; the support is mounted on the device housing; the moving mechanism is movably connected to the support; and the hanging mechanism includes a support component, a drive component, and an adjustment component. In this embodiment of the suspended shot blasting machine, the hanging mechanism, through the cooperation of the drive component and the adjustment component, drives a drive gear to rotate. The drive gear, through meshing transmission, synchronously drives three elliptical gears to rotate, thereby causing the workpieces suspended on the three hooks to rotate as a whole. Simultaneously, during the rotation of the elliptical gears, a guide rod moves along the guide groove of a triangular plate.

This ensures that all areas of the workpiece surface make more comprehensive contact with the shot blasting range of the shot blasting unit, avoiding shot blasting dead zones.

Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a hanging shot blasting machine. Background Technology

[0002] Shot blasting machines are surface treatment equipment that uses high-speed shot to clean or strengthen the surface of workpieces. They are widely used in machinery manufacturing, automotive parts, shipbuilding, steel structures, and other fields. Currently, based on their structural form and application scenarios, shot blasting machines can be classified into drum-type shot blasting machines, crawler-type shot blasting machines, through-type shot blasting machines, and hook-type shot blasting machines. Among them, hook-type shot blasting machines require the workpiece to be hung on a hook using a lifting device. Then, the hook drives the workpiece along a track into a closed shot blasting chamber. Shot is then ejected by the shot blasting unit to impact and clean or strengthen the surface of the workpiece. During the shot blasting process, the hook, driven by a drive mechanism, slowly rotates the workpiece to perform the shot blasting operation.

[0003] However, in actual production, small workpieces are usually handled by multiple-piece centralized hanging, that is, by stringing or grouping multiple small workpieces to the same lifting device. Although the hook can drive the lifting device to rotate as a whole, the close arrangement of multiple workpieces can easily cause mutual obstruction between adjacent workpieces. Moreover, the single rotation direction of the hook can only ensure that the outer surface of the workpiece facing the shot blasting unit can fully contact the shot. The inner areas where the workpieces are in contact with each other and the corners and edges that are obstructed by the lifting device are always in the blind zone of shot blasting and cannot be effectively impacted and cleaned or strengthened. This leads to problems such as incomplete rust removal, uneven surface roughness, and insufficient strengthening layer thickness in these dead corner areas, which affects the quality of treatment. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose a suspended shot blasting machine that can use a suspension mechanism to drive the workpiece suspended on the hook to rotate on its own axis while revolving around the center of the orbit, so that all areas of the workpiece surface can come into more comprehensive contact with the shot blasting range of the shot blasting unit, avoiding shot blasting dead zones and improving the uniformity and consistency of the workpiece surface treatment.

[0006] To achieve the above objectives, the first aspect of this utility model provides a suspended shot blasting machine, comprising: a device housing, a support, a moving mechanism, and a suspension mechanism, wherein a shot blasting unit is disposed within the device housing; the support is disposed on the device housing; the moving mechanism is movably connected to the support; the suspension mechanism includes a support component, a driving component, and an adjusting component, wherein the support component is disposed at the bottom of the moving mechanism, and the support component is movably connected to the support through the moving mechanism; the adjusting component is disposed on the support component; the driving component is disposed on the support component, and the driving component is located between the adjusting component and the support component, and the output end of the driving component is connected to the adjusting component.

[0007] In addition, the suspended shot blasting machine proposed above according to this utility model may also have the following additional technical features: Specifically, the moving mechanism includes two linear guide rails and a moving seat, wherein the two linear guide rails are symmetrically arranged on the bracket; the moving seat is movably connected to the linear guide rails and is connected to the support assembly.

[0008] Specifically, the support assembly includes a first connecting rod and a second connecting rod, wherein the first connecting rod is disposed at the bottom of the movable seat; the second connecting rod is disposed at the end of the first connecting rod away from the movable seat, and the second connecting rod is connected to the driving member.

[0009] Specifically, the adjustment assembly includes a triangular plate, three rotating blocks, a drive gear, three elliptical gears, and three sets of guide rods. The triangular plate is located at the bottom of the second connecting rod and has a guide groove. The three rotating blocks are equally spaced within the triangular plate on the side of the guide groove. The drive gear is movably connected to the bottom of the triangular plate, with its shaft extending through the triangular plate and connected to the output end of the drive component. The three sets of guide rods are equally spaced within the guide groove, with one end of each guide rod extending through the guide groove. The three elliptical gears are respectively located at the corresponding extended ends of the guide rods, and each elliptical gear has a hook at its bottom.

[0010] Specifically, the guide groove is configured with a triangular structure, and the three elliptical gears correspond one-to-one with the three sides of the guide groove, and the three elliptical gears respectively mesh with the drive gear.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The suspended shot blasting machine of the present invention utilizes the setting of the suspension mechanism. Through the cooperation of the driving component and the adjustment component, the driving gear is driven to rotate. The driving gear synchronously drives the three elliptical gears to rotate through meshing transmission, thereby driving the workpieces suspended on the three hooks to achieve overall rotation. At the same time, during the rotation of the elliptical gears, the guide rod will move along the guide groove of the triangular plate. When the guide rod moves, it intermittently abuts against the rotating block, causing the elliptical gears to rotate on their own axis while revolving with the driving gear, thereby driving the workpieces suspended on the hooks to rotate. This allows all areas of the workpiece surface to come into more comprehensive contact with the shot blasting range of the shot blasting unit, avoiding shot blasting dead zones and improving the uniformity and consistency of the workpiece surface treatment.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] The suspended shot blasting machine of this utility model is described below with reference to the accompanying drawings.

[0017] like Figures 1-4 As shown, a suspended shot blasting machine according to an embodiment of the present invention may include a device housing 1, a support 2, a moving mechanism 3, and a suspension mechanism 4.

[0018] The device housing 1 contains a shot blasting unit 11, and the support 2 is mounted on the device housing 1.

[0019] It should be noted that the device housing 1 described in this embodiment is hinged with a door to prevent shot blasting and dust spillage during the shot blasting process.

[0020] The moving mechanism 3 is movably connected to the support 2. The hanging mechanism 4 includes a support component 41, a driving component 42, and an adjusting component 43. The support component 41 is located at the bottom of the moving mechanism 3 and is movably connected to the support 2 through the moving mechanism 3. The adjusting component 43 is located on the support component 41. The driving component 42 is located on the support component 41 and is located between the adjusting component 43 and the support component 41. The output end of the driving component 42 is connected to the adjusting component 43.

[0021] It should be noted that the driving component 42 described in this embodiment is preferably a servo motor, which drives the adjustment component 43 to rotate, ensuring that the workpiece can adjust its angle according to the blasting range of the shot blasting unit 11 during the shot blasting process, thereby improving work efficiency.

[0022] Specifically, before the operation, the moving mechanism 3 drives the hanging mechanism 4 to move out of the device box 1 as a whole. At this time, the workers can hang the workpiece to be processed on the adjusting component 43. After the workpiece is hung, the moving mechanism 3 is started, so that the moving mechanism 3 drives the hanging mechanism 4 and the workpiece to move along the bracket 2 into the device box 1. When the workpiece is completely inside the shot blasting chamber of the device box 1, the hinged box door is closed to prevent shot from splashing and dust from overflowing during the shot blasting process.

[0023] Furthermore, when the shot blasting unit 11 is started, the drive component 42 is also started. The drive component 42 will drive the adjustment component 43 to rotate, so that the adjustment component 43 synchronously drives the workpiece to rotate, so that each area of ​​the workpiece surface can be opposite to the shot blasting unit 11, thereby achieving uniform shot blasting treatment of the workpiece surface.

[0024] In one embodiment of this utility model, such as Figure 2 As shown, the moving mechanism 3 includes two linear guide rails 31 and a moving seat 32. The two linear guide rails 31 are symmetrically arranged on the bracket 2, and the moving seat 32 is movably connected to the linear guide rails 31 and connected to the support assembly 41.

[0025] It should be noted that the movable seat 32 described in this embodiment is equipped with a matching roller structure for each of the two linear guide rails 31. The movable seat 32 also contains a power component for driving the rollers to rotate, the output end of which is connected to the roller axle. This allows the rollers to roll along the surface of the linear guide rails 31, thereby enabling the movable seat 32 to move smoothly along the linear guide rails 31 under the rolling action of the rollers. The above-described device and connection method are readily conceived and implemented by those skilled in the art, and therefore will not be elaborated upon.

[0026] Specifically, when it is necessary to transport workpieces, the movable seat 32 can drive the support assembly 41 to move together along the linear guide rail 31, thereby driving the workpieces suspended on the support assembly 41 to move synchronously, realizing internal and external transportation.

[0027] In one embodiment of this utility model, such as Figure 2 As shown, the support assembly 41 includes a first connecting rod 411 and a second connecting rod 412. The first connecting rod 411 is disposed at the bottom of the movable seat 32, and the second connecting rod 412 is disposed at the end of the first connecting rod 411 away from the movable seat 32. The second connecting rod 412 is connected to the driving member 42.

[0028] It should be noted that the first connecting rod 411 described in this embodiment is fixedly connected with bolts to ensure that the support assembly 41 can move synchronously with the movable seat 32.

[0029] Additionally, it should be noted that the first connecting rod 411 and the second connecting rod 412 described in this embodiment are vertically connected. At the same time, the top of the device housing 1 is provided with an elongated hole that is adapted to the second connecting rod 412. The length of the elongated hole matches the travel of the moving seat 32, and the width of the elongated hole is slightly larger than the second connecting rod 412, ensuring that the second connecting rod 412 can move along the elongated hole with the moving seat 32.

[0030] Specifically, when the moving mechanism 3 is started, the moving seat 32 will synchronously drive the first connecting rod 411 to move, which in turn drives the second connecting rod 412 to move synchronously. The second connecting rod 412 can drive the adjusting component 43 to move synchronously, so that the workpiece to be processed suspended on the adjusting component 43 can enter and exit the device box 1 with the supporting component 41, thereby realizing the workpiece conveying operation of shot blasting.

[0031] In one embodiment of this utility model, such as Figure 1 and Figure 4As shown, the adjustment assembly 43 includes a triangular plate 431, three rotating blocks 432, a drive gear 433, three elliptical gears 434, and three sets of guide rods 435. The triangular plate 431 is located at the bottom of the second connecting rod 412, and a guide groove 4311 is provided on the triangular plate 431. The three rotating blocks 432 are equally spaced in the triangular plate 431 on the side of the guide groove 4311. The drive gear 433 is movably connected to the bottom of the triangular plate 431, and the shaft end of the drive gear 433 extends through the triangular plate 431 and is connected to the output end of the drive component 42. The three sets of guide rods 435 are equally spaced in the guide groove 4311, and one end of the guide rod 435 extends through the guide groove 4311. The three elliptical gears 434 are respectively located at the protruding ends of the corresponding guide rods 435, and a hook 4341 is provided at the bottom of the elliptical gear 434.

[0032] It should be noted that the rotating block 432 described in this embodiment is rotatably connected to the triangular plate 431, and a torsion spring is sleeved on the shaft end of the rotating block 432. The torsion spring applies a preload to the rotating block 432 in its natural state, so that one side of the rotating block 432 extends into the guide groove 4311.

[0033] Specifically, during shot blasting, the drive unit 42 is activated, which drives the drive gear 433 to rotate. This causes the drive gear 433 to mesh and drive the three elliptical gears 434 to rotate synchronously. When the elliptical gears 434 rotate, they drive the guide rods 435 to slide along the guide grooves 4311. Since there are two guide rods 435, during the sliding process, the guide rod 435 at the front end will first come into contact with the extension end of the rotating block 432, thereby squeezing the rotating block 432 to rotate. This causes the end of the rotating block 432 to push the other guide rod 435, thereby changing the sliding direction of the elliptical gears 434. After the guide rod 435 separates from the rotating block 432, the guide rod 435 will reset and rotate under the action of the torsion spring. This achieves automatic and periodic adjustment of the workpiece during shot blasting, ensuring that each area of ​​the workpiece surface corresponds to the blasting range of the shot blasting unit 11, thus ensuring the uniformity of the shot blasting process.

[0034] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the guide groove 4311 is a triangular structure, and the three elliptical gears 434 correspond one-to-one with the three sides of the guide groove 4311, and the three elliptical gears 434 mesh with the drive gear 433 respectively.

[0035] It should be noted that the three elliptical gears 434 described in this embodiment form a star-shaped meshing transmission structure with the central drive gear 433. When the drive gear 433 rotates, it can synchronously drive the three elliptical gears 434 to rotate in the same or opposite directions, thereby realizing the synchronous angle adjustment of the workpieces suspended on the three hooks 4341.

[0036] Specifically, when the drive gear 433 rotates, the rotation of the drive gear 433 can synchronously drive the three elliptical gears 434 to rotate, so that the three elliptical gears 434 rotate synchronously in the same or opposite directions, so that the actions of the three hooks 4341 are consistent, ensuring that the surface of each workpiece is in full contact with the shot blasting unit 11, thereby ensuring the quality stability and work efficiency of multi-workpiece shot blasting.

[0037] Additionally, it should be noted that, in order to prevent the shot from getting stuck in the guide groove 4311 during the shot blasting process and affecting the operation of the adjustment component 43, a protective shell can be provided on the outside of the triangular plate 431 in this embodiment. The protective shell only has an adaptation opening reserved in the direction of the extension of the guide rod 435, thereby preventing the shot from splashing directly into the guide groove 4311 and ensuring the normal operation of each component.

[0038] In summary, this utility model of a suspended shot blasting machine utilizes a suspended mechanism. Through the cooperation of a drive component and an adjustment assembly, a drive gear is driven to rotate. The drive gear, through meshing transmission, synchronously drives three elliptical gears to rotate, thereby causing the workpieces suspended on the three hooks to rotate as a whole. Simultaneously, during the rotation of the elliptical gears, the guide rods move along the guide grooves of the triangular plates. When the guide rods move, they intermittently abut against the rotating blocks, causing the elliptical gears to rotate on their own axis while revolving with the drive gears. This, in turn, causes the workpieces suspended on the hooks to rotate, ensuring that all areas of the workpiece surface come into more comprehensive contact with the shot blasting unit's blasting range, avoiding shot blasting dead zones, and improving the uniformity and consistency of the workpiece surface treatment.
