A hook-type shot blasting machine

Abstract

This invention provides a hook-type shot blasting machine. A drive wheel is rotatably mounted on a support frame, which drives a switching frame to reciprocate. A swing arm is hinged to the support frame to drive the drive wheel's reciprocating rotation. A lever is installed on the first hook. When the first hook moves towards the cleaning chamber, the lever drives the swing arm to swing, which in turn drives the drive wheel to rotate, thus moving the switching frame. This connects the switching rollers on the switching frame between the first track and the main track, allowing the first hook to move onto the main track. When the first hook moves back onto the first track, the lever drives the swing arm to swing in the opposite direction, causing the switching frame to move in the opposite direction. This connects another switching track between the second track and the main track, allowing the second hook to move onto the main track. This allows the switching frame to automatically switch based on the position of the first hook, reducing errors caused by manual operation.

Description

Technical Field

[0001] This invention belongs to the field of shot blasting machine technology, specifically relating to a hook-type shot blasting machine. Background Technology

[0002] A shot blasting machine is a device that uses high-speed shot blasting to clean or strengthen the surface of castings. Shot blasting machines can simultaneously perform sand removal, core removal, and cleaning on castings. They are widely used in the field of casting parts processing technology. Currently, most shot blasting machines on the market are hook-type shot blasting machines and crawler-type shot blasting machines. Hook-type shot blasting machines typically use a double-hook configuration. This allows two hooks to alternately enter the cleaning chamber, improving the efficiency of loading, unloading, and cleaning operations. Double-hook shot blasting machines require a switching track between the two hook tracks, allowing a single hook track to connect to the main track. However, currently, the position of the switching track needs to be manually controlled. Operators must repeatedly operate the switching track and hooks during use, making the operation complex and increasing the machine's accident rate. Summary of the Invention

[0003] This invention provides a hook-type shot blasting machine, which aims to solve the problem that existing hook-type shot blasting machines are complex to operate and prone to machine accidents during use.

[0011] The swing arm is hinged in the middle to the support frame, and one end of the swing arm is provided with an arc-shaped toothed bar that meshes with the gear.

[0012] A lever, installed on the first hook, is used to actuate the other end of the swing arm and cause the swing arm to swing when the first hook slides on the first track.

[0013] In one possible implementation, a transmission assembly is further provided between the gear and the drive wheel, the transmission assembly comprising:

[0014] The worm gear is rotatably mounted on the support frame and installed on the rotating shaft of the drive wheel;

[0015] The worm gear is rotatably mounted on the support frame and meshes with the worm wheel. The gear is mounted on the rotating shaft of the worm gear.

[0016] In one possible implementation, a transmission unit is further provided between the support frame and the switching frame, the transmission unit comprising:

[0017] Two fixing blocks are installed on the support frame.

[0018] The switching frame has two movable wheels, which are arranged at intervals along the first direction and are rotatably mounted on the switching frame.

[0019] There are two guide wheels, which are rotatably mounted on the support frame and are spaced apart on the support frame along the first direction. The distance between the two guide wheels is greater than the distance between the two movable wheels, and the two guide wheels are located on both sides of the two movable wheels.

[0020] The conveyor belt is fixedly mounted on the fixed block at both ends and is sequentially wrapped around the outside of the moving wheel and the guide wheel, and the conveyor belt is rotatably connected to the drive wheel.

[0021] In one possible implementation, the end of the lever is equipped with a toothed rod that slides along the first hook in the longitudinal direction, and the end of the rocker arm is provided with external teeth that mesh with the toothed rod.

[0022] In one possible implementation, the first hook includes:

[0023] Housing, the lever is mounted on the housing;

[0024] The roller is rotatably disposed inside the housing and rollably disposed inside the first track;

[0025] A driving component is mounted on the housing, and the driving end of the driving component is connected to the roller drive to drive the roller to rotate.

[0026] In one possible implementation, an anti-slip component is further provided between the first hook and the first track to prevent the roller from being unable to move inside the first track when the lever abuts against the rocker arm.

[0027] In one possible implementation, the anti-slip component includes:

[0028] A fixed rack is fixedly installed on the first track;

A swing arm is also hinged to the support frame to drive the drive wheel to reciprocate. A lever is installed on the first hook. When the first hook moves towards the cleaning chamber, the lever drives the swing arm to swing, which in turn drives the drive wheel to rotate, thus moving the switching frame. This connects the switching rollers on the switching frame between the first track and the main track, allowing the first hook to move onto the main track. When the first hook moves back onto the first track, the lever drives the swing arm to swing in the opposite direction, causing the switching frame to move in the opposite direction. This connects another switching track between the second track and the main track, allowing the second hook to move onto the main track. This allows the switching frame to automatically switch based on the position of the first hook, reducing errors caused by manual operation. Attached Figure Description

[0040] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0041] Please refer to the following: Figures 1 to 4 The hook-type shot blasting machine provided by the present invention will now be described. The hook-type shot blasting machine includes a cleaning chamber 1, a mounting frame 2, a main track 3, a support frame 4, a switching frame 5, a drive wheel 6, a swing arm 7, and a lever 411. The mounting frame 2 is installed on the top of the cleaning chamber 1; the main track 3 is installed on the mounting frame 2 and is located above the cleaning chamber 1; the support frame 4 is connected to the front side of the mounting frame 2, and a first track 41 and a second track 42 are symmetrically arranged on the support frame 4, with a first hook 8 and a second hook respectively installed on the first track 41 and the second track 42; the switching frame 5 is slidably arranged on the support frame 4, and has two switching tracks 51 respectively for connecting the first track 41 and the main track 3 and for connecting the second track 42 and the main track 3. The sliding direction of the switching frame 5 is the first direction; the drive wheel 6 is rotatably mounted on the support frame 4, and the drive wheel 6 is connected to the switching frame 5 for driving the switching frame 5 to slide on the support frame 4. The rotating shaft of the drive wheel 6 is connected to the gear 43; the middle part of the swing rod 7 is hinged on the support frame 4, and one end of the swing rod 7 is provided with an arc-shaped toothed bar that meshes with the gear 43; the lever 411 is mounted on the first hook 8. When the first hook 8 slides on the first track 41, it is used to move the other end of the swing rod 7 and drive the swing rod 7 to swing.

[0042] Compared with the prior art, the hook-type shot blasting machine provided in this embodiment has a mounting frame 2 installed above the cleaning chamber 1, and a main track 3 installed on the mounting frame 2. The first track 41 and the second track 42 can be connected to the main track 3 through the switching frame 5, so that the first hook 8 or the second hook can slide onto the main track 3, and the product on the first hook 8 or the second hook can be moved into the cleaning chamber 1. In this application, a drive wheel 6 is rotatably provided on the support frame 4, and the drive wheel 6 can drive the switching frame 5 to move back and forth. A swing arm 7 for driving the drive wheel 6 to rotate back and forth is also hinged on the support frame 4. A lever 411 is installed on the first hook 8. When the first hook 8 moves towards the cleaning chamber 1, the lever 411 drives the swing arm 7 to swing, and the swing arm 7 drives the drive wheel 6 to rotate, thereby moving the switching frame 5, so that the switching roller on the switching frame 5 connects between the first track 41 and the main track 3, so that the first hook 8 can move onto the main track 3. When the first hook 8 moves back onto the first track 41, the lever drives the swing arm 7 to swing in the opposite direction, thereby causing the switching frame 5 to move in the opposite direction. This connects another switching track 51 between the second track 42 and the main track 3, allowing the second hook to move onto the main track 3. This enables the switching frame 5 to automatically switch according to the position of the first hook 8, reducing errors caused by manual operation.

[0043] Specifically, in this embodiment, a clearance for avoiding the gear 43 is provided in the middle of the rocker arm 7, the arc-shaped toothed rod is located on the inner wall of the clearance, and the axis of the arc-shaped toothed rod is coaxial with the hinge axis of the rocker arm 7 on the support frame 4.

[0044] In some embodiments, the drive wheel 6 may be as follows: Figure 1 , Figure 2 and Figure 3 The structure shown. See also... Figure 1 , Figure 2 and Figure 3 A transmission assembly is also provided between gear 43 and drive wheel 6, including a worm gear 72 and a worm 71. The worm gear 72 is rotatably mounted on the support frame 4 and installed on the rotating shaft of the drive wheel 6; the worm 71 is rotatably mounted on the support frame 4 and meshes with the worm gear 72, with gear 43 installed on the rotating shaft of the worm 71. The worm gear 72 is installed on the rotating shaft of the drive wheel 6 and is coaxial with the shaft. When the worm gear 72 rotates, it drives the drive wheel 6 to rotate as well. The outer diameter of the worm gear 72 is smaller than the outer diameter of the drive wheel 6. The worm 71 is coaxial with gear 43 and shares the same rotating shaft. When the rocker arm 7 drives gear 43 to rotate, the worm 71 rotates with gear 43, thereby driving the worm gear 72 to rotate, thus rotating the drive wheel 6. Simultaneously, the connection between the worm gear 72 and the screw prevents the worm gear 72 from rotating on its own in the free state, ensuring the stability of the switching frame 5 position.

[0045] In some embodiments, the transmission unit 61 described above may employ, for example... Figure 1 The structure shown. See also Figure 1 A transmission unit 61 is also provided between the support frame 4 and the switching frame 5. The transmission unit 61 includes a fixed block 611, a movable wheel 612, a guide wheel 613, and a conveyor belt 614. There are two fixed blocks 611, which are mounted on the support frame 4. There are two movable wheels 612, which are arranged at intervals along a first direction on the switching frame 5 and are rotatably mounted on the switching frame 5. There are two guide wheels 613, which are rotatably mounted on the support frame 4 and are arranged at intervals along a first direction on the support frame 4. The distance between the two guide wheels 613 is greater than the distance between the two movable wheels 612, and the two guide wheels 613 are located on both sides of the two movable wheels 612. The two ends of the conveyor belt 614 are fixedly mounted on the fixed blocks 611 respectively, and are sequentially wrapped around the outside of the movable wheels 612 and the guide wheels 613. The conveyor belt 614 is rotatably connected to the drive wheel 6. The two ends of the conveyor belt 614 are fixedly mounted on two fixed blocks 611, and the conveyor belt 614 is meshed with the moving wheels 612, guide wheels 613, and drive wheels 6. When the drive wheels 6 rotate, they can drive the conveyor belt 614 to move, thereby changing the length of the conveyor belt 614 on both sides of the drive wheels 6, so as to pull the two moving wheels 612 to move in the same direction, realizing the change of position of the switching frame 5. At the same time, the arrangement of the two moving wheels 612 ensures that the force on the moving wheels 612 is set along the first direction, thus ensuring the stability of the movement of the switching frame 5.

[0046] Specifically, in this embodiment, teeth are provided on both sides of the conveyor belt 614, and teeth that mesh with the teeth on the conveyor belt 614 are provided on the outer sides of the moving wheel 612, the guide wheel 613 and the drive wheel 6.

[0047] Optionally, in this embodiment, the conveyor belt 614 may be a chain, and the moving wheel 612, guide wheel 613 and drive wheel 6 are sprockets that cooperate with the chain.

[0048] In some embodiments, the aforementioned toggle block 411 may employ, for example... Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3The end of the lever 411 is equipped with a toothed rod 412, which is arranged along the sliding direction of the first hook 8 in the longitudinal direction. The end of the swing arm 7 is provided with external teeth 73 that mesh with the toothed rod 412. The toothed rod 412 is located at the end of the lever 411 away from the first hook 8. When the first hook 8 moves, it can drive the toothed rod 412 to move together. When the toothed rod 412 moves to the end of the swing arm 7, the toothed rod 412 meshes with the end of the swing arm 7, thereby causing the toothed rod 412 to drive the swing arm 7 to swing. The swing arm 7 can be driven to swing during the reciprocating movement of the first hook 8.

[0049] Specifically, in this embodiment, an arc-shaped portion is provided at the end of the swing arm 7. The axis of the arc-shaped portion is coaxial with the hinge axis of the swing arm 7 on the support frame 4, and the teeth are located on the arc-shaped portion.

[0050] In some embodiments, the first hook 8 described above can be as follows: Figure 2 The structure shown. See also Figure 2 The first hook 8 includes a housing 81, a roller 82, and a drive component 83. A lever 411 is mounted on the housing 81; the roller 82 is rotatably disposed inside the housing 81 and rolls within the first track 41; the drive component 83 is mounted on the housing 81, and its drive end is connected to the roller 82 for driving the roller 82 to rotate. At least one roller 82 is rotatably disposed on the housing 81. The drive component 83 is a motor, and its operating state can be controlled to drive the roller 82 to rotate, thereby achieving the rolling of the roller 82 on the first track 41 and adjusting the position of the housing 81. A mounting bracket 2 for mounting components is installed at the bottom of the housing 81, allowing the mounting bracket 2 to move along with the housing 81.

[0051] In some embodiments, the first hook 8 and the first track 41 may also be connected by a method such as Figure 2 , Figure 4 The structure shown. See also... Figure 2 , Figure 4 An anti-slip component 9 is also provided between the first hook 8 and the first track 41 to prevent the roller 82 from being unable to move inside the first track 41 when the lever 411 abuts against the swing arm 7. The anti-slip component 9 allows the lever 411 on the first hook 8 to move stably along the length of the first track 41 even when it abuts against the swing arm 7. This prevents the first hook 8 from being unable to move forward when resisted by the swing arm 7, thus improving the stability of the first hook 8 during operation.

[0052] In some embodiments, the anti-slip component 9 may employ, for example... Figure 2 , Figure 4 The structure shown. See also... Figure 2 , Figure 4The anti-slip component 9 includes a fixed rack 91 and a fixed gear 92. The fixed rack 91 is fixedly mounted on the first track 41; the fixed gear 92 is rotatably mounted on the housing 81 and is connected to the roller 82. The fixed gear 92 can move to the fixed rack 91 and meshes with it. A straight section is provided at one end of the first track 41 near the switching frame 5. The first track 41 is mounted on the straight section, and the fixed gear 92 is rotatably mounted on the housing 81. The fixed gear 92 and the roller 82 share the same drive shaft. When the drive wheel 6 drives the roller 82 to rotate, it can simultaneously drive the fixed gear 92 to rotate as well. When the housing 81 drives the fixed gear 92 to move onto the fixed rack 91, the fixed gear 92 can mesh with the rack 412. At the same time, when the drive member 83 drives the fixed gear 92 to rotate, it can achieve the effect of pushing the housing 81 to move through the cooperation between the fixed gear 92 and the fixed rack 91. To prevent the roller 82 from slipping inside the first track 41, which would prevent the housing 81 from moving.

[0053] In some embodiments, the anti-slip component 9 may employ, for example... Figure 4 The structure shown. See also Figure 4 A guide block 911 is installed at the end of the fixed gear 91 to guide the fixed gear 92 to rotate onto the fixed gear 91. The guide block 911 has teeth that can mesh with the fixed gear 92. The guide block 911 is slidably disposed at both ends of the fixed gear 91 along its length. Guide rods are fixedly installed at both ends of the fixed gear 91. The guide block 911 is slidably disposed on the guide rods, and a limiting part is installed at the end of the guide rod away from the fixed gear 91 to prevent the guide block 911 from sliding off the guide rod. The guide block 911 can mesh between two teeth of the fixed gear 92. Before the lever 411 on the housing 81 contacts the rocker arm 7, the fixed gear 92 first contacts the guide block 911, causing the guide block 911 to slide into the space between two teeth on the fixed gear 92. When the fixed gear 92 continues to rotate, it can move the housing 81 forward with the help of the guide block 911, thereby meshing with the fixed gear 91. Ensure effective meshing between the fixed gear 92 and the fixed rack 91.

[0054] In some embodiments, the guide block 911 may adopt the following... Figure 4 The structure shown. See also Figure 4An elastic element 912 is provided between the fixed gear 91 and the guide block 911 to drive the guide block 911 to slide away from the fixed gear 91. The elastic element 912 is a spring and is fitted onto the outside of the guide rod. The elastic element 912 ensures that the guide block 911 always abuts against the limiting part in the free state, allowing the guide block 911 to preferentially contact the teeth of the fixed gear 92. At the same time, the elastic element 912 provides a pushing force to the guide block 911, facilitating the guide block 911 to engage between two adjacent teeth of the fixed gear 92, ensuring that the guide block 911 and the fixed gear 92 can quickly reach the meshing state.

[0055] In some embodiments, the guide block 911 may adopt the following... Figure 4 The structure shown. See also Figure 4 The guide block 911 has a chamfer at the end away from the fixed gear 91 to facilitate meshing of the teeth with the fixed gear 92. The chamfer is located at the top of the guide block 911 on the side away from the fixed gear 91. The chamfer allows the top of the guide block 911 to more stably engage between the two teeth of the fixed gear 92.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
