Description

Technical Field

[0001] This utility model relates to the field of machining shaft parts in the automotive industry, and in particular to a centering alignment device with a buffer function. Background Technology

[0002] With rapid technological innovation and soaring labor costs, automated production has become the most effective means of cost reduction that all industries must prioritize. This is especially true in the highly competitive automotive industry. As a Tier 2 supplier in the automotive industry, labor costs will account for a very large proportion of the total product cost. Therefore, in the next few years, how to effectively reduce labor costs while ensuring quality will be the key to survival for Tier 2 suppliers in the automotive industry.

[0003] Currently, the steering rods used in automotive steering systems and shock absorber rods in automotive shock absorption systems require the bar stock to pass through double-headed lathes, centerless grinders, and other precision machining equipment due to processing requirements. The bar stock needs to roll from the machine tool processing station to the automatic frame assembly onto a tray. During this rolling process, the bar stock's position is prone to shifting, necessitating secondary positioning. Furthermore, each positioning requires centering and alignment, resulting in low work efficiency. Using other methods (such as the two-cylinder method) would increase costs, and the positioning accuracy would be affected by various external factors. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings of existing devices. This invention provides a centering alignment device with a buffer function.

[0005] This utility model is achieved through the following technical solution:

[0006] A centering alignment device with a buffer function includes a centering alignment mechanism assembly, two buffer mechanism assemblies, and two claw components. The centering alignment mechanism assembly includes a rotary cylinder and two intermediate rotary members. The two intermediate rotary members are connected to the drive end of the rotary cylinder and are located on both sides of the rotary cylinder. The rotary cylinder is used to rotate and drive the rotation of the two intermediate rotary members. One end of each of the two buffer mechanism assemblies is rotatably connected to the two intermediate rotary members, and the other end of each buffer mechanism assembly is rotatably connected to the two claw components. The buffer mechanism assembly itself is capable of telescopic movement, and the two buffer mechanism assemblies are used to drive the two claw components to move towards each other in a mutually converging direction, so that the two claw components can clamp the bar stock.

[0007] Furthermore, the centering alignment device with buffer function also includes a mounting bracket, which includes a mounting plate, a reinforcing plate, and two side plates. The two side plates are respectively connected to both ends of the mounting plate to form a U-shaped cavity between the mounting plate and the two side plates. The reinforcing plate is located in the U-shaped cavity, and both ends of the reinforcing plate are respectively connected to the two side plates. The rotary cylinder is connected to the mounting plate. The two intermediate rotary components and the two buffer mechanism assemblies are all located between the mounting plate and the reinforcing plate.

[0008] Furthermore, the centering alignment device with buffer function also includes a guide rail, which is mounted on the mounting plate. The two claw components are slidably connected to the guide rail and move along the guide rail in directions that are close to or far apart from each other.

[0009] Furthermore, the claw component includes a slider and a claw body. The slider is slidably connected to the guide rail, one end of the claw body is connected to the slider, and the other end of the claw body extends out of the mounting bracket and is used to clamp the bar stock.

[0010] Furthermore, the buffer mechanism assembly includes a buffer connecting rod, a compression spring, and a buffer mounting cylinder. The buffer mounting cylinder is rotatably connected to the pawl component. One end of the buffer connecting rod is rotatably connected to the intermediate rotating component, and the other end of the buffer connecting rod extends into the buffer mounting cylinder. The compression spring is located inside the buffer mounting cylinder, and both ends of the compression spring abut against the buffer mounting cylinder and the buffer connecting rod.

[0011] Furthermore, the buffer mounting cylinder has a plug at one end away from the pawl component, the buffer connecting rod passes through the plug, and the buffer connecting rod has a protrusion at one end away from the intermediate rotating component. The protrusion extends radially outward from the outer surface of the buffer connecting rod, and the compression spring is sleeved on the buffer connecting rod, with both ends of the compression spring abutting against the plug and the protrusion.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model discloses a centering alignment device with a buffer function. The rotation of a rotary cylinder drives two intermediate rotating components, which in turn move two buffer mechanism assemblies and two claw components in a mutually converging direction, allowing the claw components to clamp the bar stock. The buffering function of the buffer mechanism assemblies prevents scratches on the end faces of the bar stock, thus protecting both ends and extending the life of the rotary cylinder. Simultaneously, it ensures the bar stock remains centered on the tray, solving the problem of the bar stock not always remaining in the center of the tray when the product rolls onto the tray. This improves positioning accuracy, and the centering alignment mechanism only requires one rotary cylinder to ensure the bar stock is centered on the tray, thereby improving processing accuracy, increasing efficiency, and reducing costs.

[0036] Guide rail 5 Detailed Implementation

[0037] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment discloses a centering alignment device with a buffer function. The centering alignment device with a buffer function is applied to the machining field of shaft parts in the automotive industry and realizes the positioning and gripping of shaft parts, especially the positioning and gripping after the bar stock rolls into the material frame.

[0039] The centering alignment device with buffer function includes a centering alignment mechanism assembly 1, two buffer mechanism assemblies 2, and two claw components 3. The centering alignment mechanism assembly 1 includes a rotary cylinder 11 and two intermediate rotary components 12. The two intermediate rotary components 12 are connected to the drive end of the rotary cylinder 11 and are located on both sides of the rotary cylinder 11. The rotary cylinder 11 is used to rotate and drive the rotation of the two intermediate rotary components 12. One end of each of the two buffer mechanism assemblies 2 is rotatably connected to the two intermediate rotary components 12, and the other end of each buffer mechanism assembly 2 is rotatably connected to the two claw components 3. The buffer mechanism assemblies 2 themselves can extend and retract, and the two buffer mechanism assemblies 2 are used to drive the two claw components 3 to move towards each other in a mutually converging direction so that the two claw components 3 can clamp the bar material.

[0040] Two intermediate rotating parts 12 are respectively connected to both sides of the rotary cylinder 11. The rotary cylinder 11 provides driving force and drives the rotation of the two intermediate rotating parts 12, which in turn drives the two buffer mechanism assemblies 2 and the two claw components 3 to move in a mutually converging direction so that the two claw components 3 can clamp the bar stock. When a bar stock rolls to the side of the tray, the rotary cylinder 11 in the centering alignment mechanism assembly 1 drives the two intermediate rotating parts 12 to rotate. Under the force of rotation, the buffer mechanism assemblies 2 on both sides pull the claw components 3, and the claw components 3 on both sides move towards the center at the same time. Under the action of the claw components 3, the bar stock moves towards the center, thereby achieving centering alignment for each bar stock. Through the buffering function of the buffer mechanism assembly 2, the end face of the bar stock is protected from scratches, thus protecting the two end surfaces of the bar stock and extending the life of the rotary cylinder 11. Simultaneously, the two claw components 3 move towards each other and clamp the bar stock, ensuring that the bar stock remains centered on the tray. This solves the problem of the bar stock not staying centered when the product rolls into the tray, improving positioning accuracy. Furthermore, the centering alignment mechanism component 1 only requires a single rotary cylinder 11 to ensure the bar stock is centered on the tray, thereby improving processing accuracy, efficiency, and reducing costs. Additionally, during automatic tray loading, the workpiece's position within the tray remains constant, requiring no human intervention; this reduces labor intensity, saves labor costs, improves processing efficiency, and reduces bar stock manufacturing costs.

[0041] The centering alignment device with buffer function also includes a mounting bracket 4. The mounting bracket 4 includes a mounting plate 41, a reinforcing plate 43, and two side plates 42. The two side plates 42 are respectively connected to both ends of the mounting plate 41, forming a U-shaped cavity between the mounting plate 41 and the two side plates 42. The reinforcing plate 43 is located within the U-shaped cavity, and its two ends are respectively connected to the two side plates 42. A rotary cylinder 11 is connected to the mounting plate 41. Two intermediate rotary components 12 and two buffer mechanism assemblies 2 are all located between the mounting plate 41 and the reinforcing plate 43. The reinforcing plate 43 provides reinforcement, effectively strengthening the overall structural strength of the mounting bracket 4. The two intermediate rotary components 12 and the two buffer mechanism assemblies 2 are all located within the mounting bracket 4 and provide protection for them, resulting in high stability. Furthermore, the overall structure of the mounting bracket 4 is simple.

[0042] The centering alignment device with buffer function also includes a guide rail 5, which is mounted on the mounting plate 41. Two claw components 3 are slidably connected to the guide rail 5 and move along the guide rail 5 in directions that bring them closer together or further apart. The guide rail 5 has a guiding function, allowing the two claw components 3 to move in a predetermined direction, making the centering alignment device with buffer function clamp the bar stock more stably; at the same time, it effectively avoids the two claw components 3 from shifting or misaligning during movement, resulting in higher stability.

[0043] The claw component 3 includes a slider 32 and a claw body 31. The slider 32 is slidably connected to the guide rail 5. One end of the claw body 31 is connected to the slider 32, and the other end of the claw body 31 extends out of the mounting bracket 4 and is used to clamp the bar stock. The centering alignment mechanism component 1 drives two intermediate rotating parts 12 to rotate via a rotary cylinder 11. Under the force of rotation, the buffer mechanism components 2 on both sides pull the claw body 31. Guided by the guide rail 5 and the slider 32, the claw bodies 31 on both sides move towards the center simultaneously. Under the action of the claw body 31, the bar stock moves towards the center, thereby achieving centering alignment for each bar stock. The claw component 3 uses the claw body 31 to clamp the bar stock and slides on the guide rail 5 via the slider 32, resulting in high overall stability of the claw component 3; moreover, the overall structure of the claw component 3 is simple.

[0044] like Figure 5 As shown, the buffer mechanism assembly 2 includes a buffer connecting rod 21, a compression spring 23, and a buffer mounting cylinder 22. The buffer mounting cylinder 22 is rotatably connected to the pawl component 3. One end of the buffer connecting rod 21 is rotatably connected to the intermediate rotating component 12, and the other end of the buffer connecting rod 21 extends into the buffer mounting cylinder 22. The compression spring 23 is located inside the buffer mounting cylinder 22, and both ends of the compression spring 23 abut against the buffer mounting cylinder 22 and the buffer connecting rod 21. Through the retraction force of the compression spring 23, when both pawl bodies 31 on both sides are in contact with the two ends of the bar stock, the rotary cylinder 11 continues to rotate, pulling the buffer connecting rod 21 to operate. The pawl bodies 31 at both ends have already contacted the two ends of the bar stock, and the excess pulling force transferred by the rotary cylinder 11 is all transferred to the compression spring 23, thereby protecting the two ends of the bar stock and extending the life of the rotary cylinder 11. Meanwhile, the buffer connecting rod 21 extends and retracts within the buffer mounting cylinder 22, and the compression spring 23 is compressed within the buffer mounting cylinder 22, resulting in high overall structural stability.

[0045] The buffer mounting cylinder 22 has a plug 221 at the end away from the pawl component 3. The buffer connecting rod 21 passes through the plug 221. The end of the buffer connecting rod 21 away from the intermediate rotating component 12 has a protrusion 211, which extends radially outward from the outer surface of the buffer connecting rod 21. A compression spring 23 is sleeved on the buffer connecting rod 21, with both ends of the compression spring 23 abutting against the plug 221 and the protrusion 211. The compression spring 23 is sleeved on the buffer connecting rod 21 without displacement or misalignment, resulting in high stability. At the same time, the two ends of the compression spring 23 abut against the plug 221 and the protrusion 211, compressing the compression spring 23 through the plug 221 and the protrusion 211, thus ensuring high stability when the compression spring 23 is compressed.

[0046] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
