Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a high-efficiency shot blasting integrated machine for lifting hooks of bearing heat-treated parts. Background Technology

[0002] As a crucial component in equipment manufacturing, the surface quality of bearings directly determines the operational accuracy and service life of the equipment. After quenching and tempering, bearing heat-treated parts develop oxide scale and rust layers on their surface. If these are not thoroughly removed, they will severely affect the accuracy of subsequent grinding processes and assembly performance. Therefore, shot blasting has become an indispensable and critical process in bearing production. Shot blasting uses high-speed steel shot to impact the workpiece surface, which not only efficiently removes oxide scale but also forms a compressive stress layer 0.1-0.3 mm deep, increasing bearing life by 30%-50%. It is a core process for ensuring bearing reliability. To this end, patent CN210819154U discloses a high-efficiency hook-type shot blasting machine, including a shot blasting machine body, with connecting columns provided on the left front, left rear, right front, and right rear sides of the bottom of the shot blasting machine body; it also includes a filter chamber, fixing screws, and a dust pump. The filter chamber has a working chamber inside, with an upper opening at the top of the working chamber that communicates with the working chamber. A sealing cover is provided at the top of the upper opening, and the sealing cover is connected to the top of the filter chamber by fixing screws. A water outlet pipe is connected to the lower right side of the working chamber, and a control valve is provided on the sealing cover. The bottom of the dust pump is connected to the top of the filter chamber, and a first air supply pipe is connected to the bottom input end of the dust pump. The bottom end of the first air supply pipe passes through the top of the filter chamber and extends into the working chamber of the filter chamber. An air outlet pipe is connected to the top output end of the dust pump. The existing technical solutions described above have the following drawbacks: when in use, it is inconvenient to perform multi-angle shot blasting on the suspended bearings, thereby affecting the range of shot blasting of the bearing components and reducing processing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency shot blasting machine for bearing heat treatment parts, which solves the problem that existing high-efficiency shot blasting machines with hooks are inconvenient for multi-angle shot blasting of suspended bearings.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency shot blasting machine with a hook for heat-treated bearing parts, including a hook-type shot blasting machine body; The top of the hook-type shot blasting machine body is equipped with a support frame, the bottom of the support frame is equipped with a guide rail, the outer wall of the guide rail is movably connected to a feeding trolley, the outer wall of the feeding trolley is fixedly connected to a receiving rod, and one end of the receiving rod is fixedly connected to an angle adjustment mechanism. The angle adjustment mechanism includes a tray fixedly installed at one end of a receiving rod. A forward and reverse motor is fixedly installed on the outer wall of the tray. The output shaft of the forward and reverse motor is fixedly connected to a first rotating rod via a coupling. A first bevel gear is fixedly connected to one end of the first rotating rod, and a second bevel gear is movably connected to the outer wall of the first bevel gear.

[0005] Preferably, a second rotating rod is fixedly connected to the bottom of the second bevel gear, a retaining ring is fixedly connected to the outer wall of the second rotating rod, a hook is fixedly connected to the bottom of the second rotating rod, and a hanger is installed on the outer wall of the hook.

[0006] Preferably, the first bevel gear forms a rotating structure with the tray via a first rotating rod, and the first bevel gear meshes with the second bevel gear.

[0007] Preferably, the second bevel gear forms a rotating structure with the tray via the second rotating rod, and the hook forms a rotating structure with the tray via the second rotating rod.

[0008] Preferably, the first bevel gear and the second bevel gear are distributed perpendicularly, and the retaining ring is symmetrically arranged about the central axis of the tray.

[0009] Preferably, a movable block is fixedly connected to the outer wall of the second rotating rod, and a guide sleeve is movably connected to the outer wall of the second rotating rod. A through groove is opened inside the guide sleeve, and a reciprocating groove is opened on the inner side wall of the through groove. An L-shaped bracket is fixedly connected to the outer wall of the guide sleeve.

[0010] Preferably, the second rotating rod forms a rotating structure with the guide sleeve through a through groove, and the movable block forms a sliding structure with the guide sleeve through a reciprocating groove.

[0011] The advantages of the high-efficiency shot blasting machine for bearing heat treatment parts provided by this utility model are as follows: By setting up an angle adjustment mechanism and a hanger, and by starting the forward and reverse motor, the first bevel gear fixedly connected to one end of the first rotating rod can be rotated back and forth in both directions, causing the second bevel gear to rotate, thereby driving the hook installed at the bottom of the second rotating rod to rotate back and forth in both directions. This facilitates the reciprocating rotation of the bearings mounted on the hanger, thereby increasing the range of the bearings that can be shot blasted. Furthermore, the retaining ring can improve the stability of the second rotating rod as it rotates along the tray; Furthermore, since the size of the first bevel gear is smaller than that of the second bevel gear, the rotational stability of the second bevel gear can be improved, thereby further improving the stability of the hook's reciprocating rotation. With the angle adjustment mechanism, as the second rotating rod reciprocates, the movable block can slide back and forth along the reciprocating groove, and the second rotating rod can slide back and forth up and down along the guide sleeve, so that the hanger hanging on the outer wall of the hook can move back and forth up and down, further increasing the range of shot blasting for the bearings suspended on the hanger. Furthermore, since the guide sleeve is movably fitted onto the outer wall of the second rotating rod, the stability of the second rotating rod's rotation and lifting can be further improved.

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.

[0015] Please see Figures 1-7 The present invention provides a high-efficiency shot blasting machine for bearing heat treatment parts, including a hook-type shot blasting machine body 1.

[0016] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a support frame 2 is installed on the top of the main body 1 of the hook-type shot blasting machine, and a guide rail 3 is installed on the bottom of the support frame 2. A feeding trolley 4 is movably connected to the outer wall of the guide rail 3, and a receiving rod 5 is fixedly connected to the outer wall of the feeding trolley 4. An angle adjustment mechanism 6 is fixedly connected to one end of the receiving rod 5. The angle adjustment mechanism 6 includes a tray 61 fixedly installed at one end of the receiving rod 5. A forward and reverse motor 62 is fixedly installed on the outer wall of the tray 61. The output shaft of the forward and reverse motor 62 is fixedly connected to a first rotating rod 63 through a coupling. A first bevel gear 64 is fixedly connected to one end of the first rotating rod 63, and a second bevel gear 65 is movably connected to the outer wall of the first bevel gear 64. The bottom of the second bevel gear 65 is fixedly connected to the second rotating rod 66, the outer wall of the second rotating rod 66 is fixedly connected to the retaining ring 67, the bottom of the second rotating rod 66 is fixedly connected to the hook 68, and the outer wall of the hook 68 is equipped with a hanger 7. The first bevel gear 64 forms a rotating structure with the tray 61 through the first rotating rod 63. The first bevel gear 64 and the second bevel gear 65 are meshed and connected. The second bevel gear 65 forms a rotating structure with the tray 61 through the second rotating rod 66. The hook 68 forms a rotating structure with the tray 61 through the second rotating rod 66. The first bevel gear 64 and the second bevel gear 65 are vertically distributed, and the retaining ring 67 is symmetrically arranged about the central axis of the tray 61.

[0017] By hanging the bearings on the hanger 7 and suspending the hanger 7 full of bearings on the hook 68, starting the feed trolley 4 allows it to slide along the guide rail 3, driving the hanger 7 to be transported into the main body 1 of the hook-type shot blasting machine. Starting the forward and reverse motor 62 causes the first bevel gear 64, which is fixedly connected to one end of the first rotating rod 63, to rotate back and forth. Since the first bevel gear 64 is meshed with the second bevel gear 65, the second bevel gear 65 can rotate, thereby driving the hook 68 installed at the bottom of the second rotating rod 66 to rotate back and forth, so that the bearings hanging on the hanger 7 are rotated back and forth, making the shot blasting process more uniform.

[0018] Reference Figure 6 and Figure 7 As shown, a movable block 661 is fixedly connected to the outer wall of the second rotating rod 66, and a guide sleeve 662 is movably connected to the outer wall of the second rotating rod 66. A through groove 663 is provided inside the guide sleeve 662, and a reciprocating groove 664 is provided on the inner side wall of the through groove 663. An L-shaped bracket 665 is fixedly connected to the outer wall of the guide sleeve 662. The L-shaped bracket 665 is fixedly installed on the bottom of the tray 61. The second rotating rod 66 and the guide sleeve 662 form a rotating structure through the through groove 663, and the movable block 661 and the guide sleeve 662 form a sliding structure through the reciprocating groove 664.

[0019] As the second rotating rod 66 reciprocates, it can reciprocate along the through groove 663 inside the guide sleeve 662, causing the movable block 661 to slide back and forth along the reciprocating groove 664. Since the guide sleeve 662 is fixedly installed below the tray 61, the second rotating rod 66 can slide back and forth up and down along the guide sleeve 662, causing the hanger 7 suspended on the outer wall of the hook 68 to move back and forth up and down.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, 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 the present invention should be included within the protection scope of the present invention.
