Description

Technical Field

[0001] This invention relates to the field of molding and manufacturing technology, specifically to a prestressed fixture for laser shot peening forming of integral ribbed components. Background Technology

[0002] Shot peening is a widely used surface strengthening process in factories. It involves bombarding the surface of a workpiece with shot to implant residual compressive stress, thereby improving the workpiece's fatigue strength. It is widely used to improve the mechanical strength, wear resistance, fatigue resistance, and corrosion resistance of parts. The advantages of shot peening are simple equipment, low cost, no limitations on workpiece shape and location, and convenient operation. The disadvantages are a harsh working environment, low unit output, and lower efficiency than shot blasting. Types of shot used for peening include steel shot, cast iron shot, glass shot, and ceramic shot.

[0003] Existing shot peening equipment requires clamping and deforming the ribbed component before shot peening, and then polishing the ribbed component using the shot peening equipment. However, the component needs to be cleaned before shot peening. When the clamp deforms the ribbed component, dust is easily generated on the surface of the component. The dust on the surface of the component needs to be cleaned separately before shot peening. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the above and / or the existing prestressed fixture for laser shot peening forming of integral ribbed components, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a prestressed fixture for laser shot peening of integral ribbed components. This fixture features a base with a slidably connected housing inside. A drive assembly is located at the bottom of the housing, and two clamping plates are symmetrically arranged inside the housing. A deformation assembly is also located inside the housing, and a dust removal assembly is located on the side wall of the housing. Before shot peening, the ribbed component is placed inside the housing. As the drive assembly moves the housing towards the rear end of the base, it causes the two clamping plates to move closer together and clamp the component. Simultaneously, the two clamping plates move closer together, causing the deformation assembly to bulge upwards, cooperating with the clamping plates to deform the component. At the same time, the dust removal assembly removes the dust generated during the deformation of the component as the housing moves. This process continues until the housing reaches the rear end of the base and is located at the bottom of the shot peening equipment. Shot peening of the deformed component is then performed without the need for additional dust removal, thus improving shot peening efficiency.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0040] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0041] This invention provides a prestressed fixture for laser shot peening of integral ribbed components. A base is provided, with a housing slidably connected inside. A drive assembly is located at the bottom of the housing, and two clamping plates are symmetrically arranged inside the housing. A deformation assembly is also located inside the housing, and a dust removal assembly is located on the side wall of the housing. Before shot peening, the ribbed component is placed inside the housing. As the drive assembly moves the housing towards the rear end of the base, it causes the two clamping plates to move closer together and clamp the component. Simultaneously, the two clamping plates move closer together, causing the deformation assembly to bulge upwards, cooperating with the clamping plates to deform the component. At the same time, the dust removal assembly removes the dust generated during the deformation of the component as the housing moves. The process continues until the housing reaches the rear end of the base and is located at the bottom of the shot peening equipment. Shot peening of the deformed component is then performed without the need for separate dust removal, thus improving shot peening efficiency.

[0042] Figure 1-9 The diagram shown is a structural schematic of one embodiment of the laser shot peening prestressed fixture for integral ribbed components according to the present invention. Please refer to [link / reference]. Figures 1-9 The laser shot peening prestressed fixture for integral ribbed components according to this embodiment includes a base 100, a housing 200, a drive assembly 300, a clamping plate 400, a deformation assembly 500, a dust removal assembly 600, a pop-out assembly 700, and a deceleration assembly 800.

[0043] The tail end of the base 100 is located at the bottom of the external shot peening equipment. A first rack 110 is installed on the inner wall of the base 100. Two second racks 120 are symmetrically installed on the top of the base 100. A first guide groove 130 is opened on the inner wall of the base 100.

[0044] A first gear 210 is rotatably connected to the side wall of the housing 200. The first gear 210 meshes with one of the second racks 120. A first helical gear 210a is installed on the side wall of the first gear 210. A threaded rod 220 with both positive and negative threads is rotatably connected inside the housing 200. One end of the threaded rod 220 extends out of the side wall of the housing 200 and is fitted with a second helical gear 220a, which meshes with the first helical gear 210a. A first guide plate 250 is installed on the symmetrical side walls of the housing 200, extending into the first guide groove 130. A second gear 230 is rotatably connected to the tail end of the housing 200. A first reciprocating threaded rod 230a is installed on the side wall of the second gear 230, which meshes with another second rack 120. A first pulley 230b is installed on the other side wall of the second gear 230. A second pulley 240 is rotatably connected to the front end of housing 200. The first pulley 230b and the second pulley 240 are connected by a belt. A second reciprocating threaded rod 240a is installed on the side wall of the second pulley 240. When housing 200 slides backward inside base 100, as housing 200 slides, one of the second racks 120 drives the first gear 210 to rotate. The first gear 210 drives the first helical gear 210a to rotate. The first helical gear 210a drives the second helical gear 220a and the threaded rod 220 to rotate using its teeth. At the same time, the other second rack 120 drives the second gear 230 to rotate. The second gear 230 drives the first reciprocating threaded rod 230a and the first pulley 230b to rotate. When the first pulley 230b rotates, it drives the second pulley 240 and the second reciprocating threaded rod 240a to rotate using the belt.

[0045] The drive assembly 300 includes two mounting plates 310 symmetrically mounted on the bottom of the housing 200, a dual-axis motor 320 mounted on the bottom of the housing 200, and two third gears 330 rotatably connected to the side walls of the two mounting plates 310. The two drive assemblies 300 are respectively connected to the two output shafts of the dual-axis motor 320. By starting the dual-axis motor 320, the two third gears 330 are driven to rotate. The third gears 330 mesh with the first rack 110. When the third gears 330 rotate clockwise, they pull the housing 200 to the tail end of the base 100. When the third gears 330 rotate counterclockwise, they pull the housing 200 to the front end of the base 100.

[0046] Two clamping plates 400 are symmetrically located inside the housing 200. When the housing 200 slides backward, the two clamping plates 400 approach each other and clamp the component. When the housing 200 moves forward, the two clamping plates 400 move away from each other. A third rack 430 is installed on the side wall of the clamping plate 400. When the threaded rod 220 rotates, the screw structure pushes the two clamping plates 400 closer to each other. When the clamping plates 400 move, the two ends of the component slide along the slope 410a until the two ends of the component are embedded in the slot 410 to clamp the component.

[0047] The deformation assembly 500 includes a protrusion 510 located inside the housing 200, a third pulley 520 rotatably connected to the bottom of the housing 200 and located below the protrusion 510, and a fourth gear 530 rotatably connected to the bottom of the housing 200. The fourth gear 530 meshes with a third rack 430. The third pulley 520 and the fourth gear 530 are connected by a belt. A threaded rod 520a is installed on the top of the third pulley 520. A second threaded hole 510a is opened at the bottom of the protrusion 510. The threaded rod 520a rotates into the second threaded hole 510a. A second guide plate is installed on the outer wall of the protrusion 510. 510b, when the clamping plates 400 move closer to each other, the third rack 430 drives the fourth gear 530 to rotate. The fourth gear 530 drives the third pulley 520 and the threaded rod 520a to rotate via a belt. When the threaded rod 520a rotates, it pushes the protrusion 510 upward using the screw structure. The protrusion 510 extends out from the top of the through hole 710a. The second guide plate 510b slides along the second guide groove spring 720b until the top of the protrusion 510 abuts against the bottom of the component. As the protrusion 510 continues to move upward, since the two ends of the component are inserted into the slot 410, the protrusion 510 lifts the center position of the component and deforms upward.

[0048] The dust removal assembly 600 includes a first pressure pipe 610 installed on the side wall of the housing 200, a first piston 620 located inside the first pressure pipe 610, a first delivery pipe 630 installed on the side wall of the first pressure pipe 610, and a second delivery pipe 640 installed on the top of the first pressure pipe 610. A fixing rod 620a is installed on the side wall of the first piston 620, and a reciprocating threaded hole 620b is formed at the side end of the fixing rod 620a. A first one-way valve 630a is installed on the body of the first delivery pipe 630, and a second one-way valve 640a is installed on the body of the second delivery pipe 640. A diversion pipe 650 is installed at the top of the second delivery pipe 640, and air pipes 650a are installed on the symmetrical side walls of the diversion pipe 650. An air nozzle 650b is installed at the other end of the air pipe 650a. Two dust removal assemblies 600 are installed, one at the tail end and the other at the front end of the housing 200. The first reciprocating threaded rod 630a and the second piston 640a are... Two reciprocating threaded rods 240a rotate and extend into two reciprocating threaded holes 620b respectively. When the first reciprocating threaded rod 230a and the second reciprocating threaded rod 240a rotate, the screw structure pushes the fixed rod 620a and the first piston 620 to reciprocate inside the first pressure tube 610. When the first piston 620 moves out of the first pressure tube 610, the first one-way valve 630a opens and the second one-way valve 640a closes, and external air enters the first pressure tube 610 through the first delivery pipe 630. When the first piston 620 moves into the first pressure tube 610, the first one-way valve 630a closes and the second one-way valve 640a opens, and the air inside the first pressure tube 610 enters the diversion pipe 650 through the second delivery pipe 640, and is sprayed out to the top of the component through the air pipe 650a and the air nozzle 650b to blow away the dust on the top of the component.

[0049] The pop-out assembly 700 includes a push plate 710 located inside the housing 200 and a spring 720 installed at the bottom of the push plate 710. The bottom end of the spring 720 is connected to the bottom of the housing 200. A through hole 710a is provided on the top of the push plate 710. A protrusion 510 is coaxial with the through hole 710a. A second guide groove 710b is provided on the inner wall of the through hole 710a at a position corresponding to the second guide plate 510b. A lifting plate 510c is installed on the bottom of the outer wall of the protrusion 510. Multiple push rods 510c-1 are installed on the top of the push plate 710. A through hole 710c is opened on the top of the push plate 710 corresponding to the push rod 510c-1. When the component is inside the housing 200, the bottom of the component abuts against the top of the push plate 710. When the slope 410a squeezes the component to move downward, the component pushes the push plate 710 to move downward and squeezes the spring 720. When the two clamping plates 400 move away from each other, the spring 720 rebounds and pushes the push plate 710 and the component to move upward, making it convenient to remove the component.

[0050] The deceleration assembly 800 includes a second pressure tube 810 installed at the bottom of the housing 200, a second piston 820 located inside the second pressure tube 810, and a connecting rod 830 installed on the top of the second piston 820. The top of the connecting rod 830 is connected to the bottom of the push plate 710. The top of the second piston 820 has multiple air holes 820a. When the ejection assembly 700 moves downward, it pushes the connecting rod 830 and the second piston 820 to move downward inside the second pressure tube 810. Air inside the second pressure tube 810 is squeezed out through the air holes 820a. When the spring 720 rebounds and pushes the push plate 710 to move upward, the push plate 710 pulls the connecting rod 830 and the second piston 820 to move upward. Air enters the second pressure tube 810 through the air holes 820a. The air pressure neutralizes the rebound force of the spring 720, slowing down the speed at which the spring 720 pushes the push plate 710 to rebound, and preventing the push plate 710 from ejecting the assembly quickly.

[0051] Combination Figures 1-9 This embodiment of a laser shot peening prestressed fixture for integral ribbed components involves placing the component inside the housing 200 and on top of the push plate 710 when shot peening is required. The dual-axis motor 320 is activated, driving the third gear 330 to rotate, pushing the housing 200 towards the tail end of the base 100. During this movement, the second rack 120 drives the first gear 210 and the second gear 230 to rotate. The first gear 210 drives the threaded rod 220 to rotate, using the screw structure to push the two clamping plates 400 closer together. The slope 410a compresses the component downwards until the housing 200 reaches the tail end of the base 100, where both ends of the component are engaged in the slots 410, fixing the component. During the movement of the clamping plates 400, the protrusions 510 push the center of the component upwards, causing deformation. Simultaneously, the housing... When the body 200 moves, the second gear 230 rotates, driving the first reciprocating threaded rod 230a to rotate. The first pulley 230b drives the second pulley 240 and the second reciprocating threaded rod 240a to rotate. The screw structure pushes the first piston 620 to reciprocate inside the first pressure tube 610, blowing air through the air nozzle 650b to the top of the component, removing the dust generated during the formation of the component top. At this time, the shot peening equipment is started to shot peen the component. After the shot peening is completed, the drive assembly 300 is started to drive the housing 200 to move towards the front end of the base 100. The two clamping plates 400 move away from each other, and the spring 720 rebounds to push the push plate 710 and the component to move upward. The deceleration assembly 800 decelerates the upward movement of the push plate 710, causing the component to rise with a buffer until the housing 200 moves to the front end of the base 100, at which point the component can be removed.

[0052] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
