Description

A track-fed bolt extractor Technical Field

[0001] The embodiments disclosed herein relate to the field of bolt processing technology, and more specifically, to a track-fed bolt extractor. Background Technology

[0002] Bolts are widely used as a basic and critical connecting component in many fields of industrial production, such as machinery manufacturing, automobile assembly, and construction. In the production processes of these industries, there is often a need to accurately and efficiently transport bolts from storage locations to processing or assembly stations. At the same time, in some scenarios, it is also necessary to remove used bolts from workpieces for recycling. This process places high demands on the performance of feeding and unloading equipment.

[0003] Traditional bolt feeding methods, some of which rely on manual feeding, are not only inefficient and labor-intensive, but also struggle to ensure consistent and accurate feeding. In large-scale production, this can easily become a bottleneck restricting production efficiency. Other methods, such as simple vibratory feeders, achieve a degree of automation, but they are poorly adaptable to complex working conditions and feeding large-sized or specially shaped bolts, often resulting in problems like jamming and untimely feeding, affecting the continuity and stability of production. For example, in the manufacturing of automotive body-in-white, with the increasing use of integrated aluminum castings in the pursuit of lightweight bodies in new energy vehicles, the demand for large-sized bolt connections has increased, and traditional feeding methods are unable to meet the requirements of highly automated and flexible production.

[0004] In the bolt removal process, manual operation using simple tools has traditionally been the primary method. For bolts with high tightness and large quantities, manual removal is time-consuming, labor-intensive, and prone to causing physical strain on operators. Furthermore, improper operation during removal can damage the workpiece. Some existing bolt removal equipment on the market is either single-function, only suitable for removing bolts of specific specifications or types, or has a complex structure, high cost, and difficult maintenance, making it difficult to widely promote and apply in small and medium-sized enterprises. For example, in the maintenance of construction machinery, a large number of bolts of different specifications need to be removed and replaced, and existing equipment cannot balance efficiency, cost, and versatility.

[0005] Therefore, it is urgent to develop a device that can efficiently and stably achieve track feeding and accurately and conveniently remove bolts. The emergence of the track feeding bolt removal machine aims to make up for the shortcomings of traditional feeding and removal methods. Through innovative structural design and working principle, it realizes the automation and efficiency of the feeding and removal process, improves the overall efficiency of bolt-related operations in industrial production, reduces production costs, and improves production safety and product quality. Summary of the Invention

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a track-fed bolt extractor, which solves the problems of traditional bolt feeding methods in the prior art. Some methods rely on manual feeding, which is not only inefficient and labor-intensive, but also makes it difficult to ensure the consistency and accuracy of feeding. In large-scale production, it can easily become a bottleneck restricting the improvement of production efficiency. Other methods use simple vibratory feeders, which achieve automation to a certain extent, but are not adaptable to complex working conditions and feeding large-sized and special-shaped bolts, and often cause technical problems such as jamming and untimely feeding.

[0007] According to one aspect, at least one embodiment of this disclosure provides a track-fed bolt extractor, comprising:

[0008] A support frame, wherein a mounting plate is provided at the upper end of the support frame;

[0009] A rotary feeding assembly is disposed on the mounting tray;

[0021] The beneficial effects of the embodiments disclosed herein are as follows:

[0022] 1. In this disclosure, the self-rotating disk in the rotary feeding assembly can quickly and accurately rotate the storage box to a predetermined position to prepare for the material feeding operation, which saves a lot of time compared to manual feeding. The material feeding motor in the material feeding assembly drives the material feeding shaft, material feeding disk and material feeding rod to rotate at high speed, which can pull out the bolts in the storage box at a very high frequency. In large-scale production scenarios, it can greatly shorten the operation cycle of a single bolt.

[0023] 2. In this disclosure, the positioning shaft and the rotary table are positioned and connected by key pins to ensure the accurate positioning of the positioning plate and the storage box during the rotation of the rotary table, avoiding inaccurate bolt feeding due to position deviation. The feeding rod has an arc-shaped structure and its end makes precise contact with the storage box, which can stably and gently pull out the bolt during the feeding process, minimizing damage to the bolt and workpiece. Compared with manual operation or some traditional equipment, it significantly reduces the product defect rate caused by improper operation and ensures the stability of product quality.

[0036] As shown in Figures 1-4, a track-fed bolt extractor of this disclosure is provided, comprising:

[0037] Support frame 1, with a mounting plate 2 at the upper end of support frame 1;

[0038] Rotary feeding assembly 3 is mounted on the mounting plate 2;

[0039] Drive the feeding assembly 4, which is mounted on the support frame 1;

[0040] The rotary feeding assembly 3 includes a crossbeam 3-1, which is set on the inner side wall of the support frame 1. A support frame 3-2 is set on the crossbeam 3-1. A drive shaft 3-3 is set on the inner side wall of the support frame 3-2. A rotating disk 3-4 is mounted on the drive shaft 3-3. A positioning shaft 3-5 is set on the side wall of the rotating disk 3-4. A positioning plate 3-6 is set on the side wall of the positioning shaft 3-5. A storage box 3-7 is connected to the internal pin of the positioning plate 3-6.

[0041] The drive feeding assembly 4 includes a drive disk 4-1, which is located on the inner side wall of the support frame 1. A drive motor 4-2 is mounted on the drive disk 4-1. A drive gear 4-3 is mounted on the output end of the drive motor 4-2. A driven gear 4-4 is mounted on the drive shaft 3-3. A drive chain 4-5 is provided between the drive gear 4-3 and the driven gear 4-4.

[0042] In some examples, support frame 1 is placed in the predetermined working position, ensuring it is stable and does not wobble. Mounting plate 2 is installed on the upper end of support frame 1 and secured using appropriate bolts or welding, ensuring that mounting plate 2 is firmly installed and level.

[0043] A crossbeam 3-1 is installed on the inner wall of the support frame 1, using bolts or other methods to ensure connection strength. A support frame 3-2 is installed on the crossbeam 3-1, ensuring it is securely installed. The drive shaft 3-3 is installed on the inner wall of the support frame 3-2, ensuring it rotates freely and is securely installed. A positioning shaft 3-5 is installed on the side wall of the rotating disk 3-4, connected to it via a key pin to ensure synchronous rotation. A positioning plate 3-6 is installed on the side wall of the positioning shaft 3-5, connected to the storage box 3-7 via a bearing and pin, allowing the storage box 3-7 to rotate freely relative to the positioning plate 3-6 while maintaining stability during rotation.

[0044] A motor mount 6 is installed on the drive disk 4-1, and the motor mount 6 is fixedly installed on the drive disk 4-1 with bolts. A drive gear 4-3 is installed at the output end of the drive motor 4-2, and a driven gear 4-4 is fitted on the drive shaft 3-3. Then, a drive chain 4-5 is installed so that the drive gear 4-3 and the driven gear 4-4 are connected by the drive chain 4-5.

[0045] Place the bolt to be removed in the storage box 3-7, start the drive motor 4-2, drive the drive gear 4-3 to rotate, drive the driven gear 4-4 and drive shaft 3-3 to rotate through the drive chain 4-5, thereby causing the spindle 3-4 to rotate, and causing the storage box 3-7 to rotate to the appropriate position. Start the feeding motor 4-8, feed motor 4-8 drives the feeding shaft 4-7 to rotate, causing the feeding disc 4-9 and feeding rod 4-10 to rotate. The feeding rod 4-10 pulls the bolt out of the storage box 3-7, completing the bolt removal operation.

[0046] As shown in Figures 1 to 4, this embodiment proposes that the self-rotating disk 3-4 has a circular structure, and a stabilizing frame 3-8 is provided inside the self-rotating disk 3-4. The stabilizing frame 3-8 is fixedly connected to the drive shaft 3-3.

[0047] In some examples, the spinner 3-4 is mounted on the drive shaft 3-3. If the spinner 3-4 is a ring structure and has a retainer 3-8 inside, the retainer 3-8 and the drive shaft 3-3 should be connected by a fixed assembly to ensure that the spinner 3-4 does not move radially or axially on the drive shaft 3-3.

[0048] For example, as shown in Figure 2, a drive frame 4-6 is provided on the side wall of the support frame 3-2, a feeding shaft 4-7 is provided on the side wall of the drive frame 4-6, a feeding motor 4-8 is provided on the side wall of the drive frame 4-6, the output end of the feeding motor 4-8 is fixedly connected to the feeding shaft 4-7, a feeding disc 4-9 is provided at the end of the feeding shaft 4-7, and a feeding rod 4-10 is provided on the side wall of the feeding disc 4-9.

[0049] In some examples, a drive frame 4-6 is installed on the side wall of the support frame 3-2, and a feeding shaft 4-7 is installed on the side wall of the drive frame 4-6. A feeding motor 4-8 is also installed, with the output end of the feeding motor 4-8 fixedly connected to the feeding shaft 4-7 to ensure stable rotation of the feeding shaft 4-7. A feeding disc 4-9 is installed at the end of the feeding shaft 4-7, and a feeding rod 4-10 is installed on the side wall of the feeding disc 4-9. The feeding rod 4-10 has an arc-shaped structure, and its end contacts the storage box 3-7, ensuring that the feeding rod 4-10 accurately moves the storage box 3-7 during rotation.

[0050] For example, as shown in Figures 1 and 2, the mounting plate 2 is provided with a drive hole 5, and the drive chain 4-5 passes through the drive hole 5.

[0051] In some examples, a drive hole 5 is provided on the mounting plate 2, and the drive chain 4-5 passes through the drive hole 5 to ensure smooth transmission of the drive chain 4-5 and to prevent interference with the mounting plate 2.

[0052] For example, as shown in Figure 2, the material feeding rod 4-10 has an arc-shaped structure, and the end of the material feeding rod 4-10 is in contact with the storage box 3-7.

[0053] For example, as shown in Figure 2, a motor platform 6 is provided at the lower end of the drive motor 4-2. The motor platform 6 is mounted on the drive disk 4-1 and is fixedly installed on the drive disk 4-1 by bolts.

[0054] In some examples, the drive motor 4-2 is mounted on the motor stand 6 to ensure that the drive motor 4-2 is securely mounted.

[0055] For example, as shown in Figure 2, a reinforcing frame 7 is provided between the horizontal frame 3-1 and the placement tray 2. The reinforcing frame 7 is vertically placed on the upper surface of the placement tray 2. The positioning tray 3-6 and the storage box 3-7 are movably connected by bearings. The positioning shaft 3-5 and the rotating disk 3-4 are positioned and inserted by key pins. The inner side wall of the support frame 1 is provided with reinforcing strips 8.

[0056] In some examples, the reinforcing frame 7 and the reinforcing strip 8 serve the same purpose: to stabilize the support frame 1.

[0057] When in use, place the bolts to be removed neatly in the storage box 3-7, start the drive motor 4-2, drive motor 4-2 drives drive gear 4-3 to rotate, drive chain 4-5 to drive driven gear 4-4 and drive shaft 3-3 to rotate, which in turn drives turntable 3-4 to rotate. During the rotation of turntable 3-4, positioning shaft 3-5, positioning plate 3-6 and storage box 3-7 rotate together, rotating storage box 3-7 to a suitable position for subsequent material removal operation.

[0058] After the storage box 3-7 is rotated to the appropriate position, the feeding motor 4-8 is started. The feeding motor 4-8 drives the feeding shaft 4-7 to rotate, thereby causing the feeding disc 4-9 and the feeding rod 4-10 to rotate. During the rotation, the arc-shaped end of the feeding rod 4-10 contacts the storage box 3-7 and pulls out the bolt in the storage box 3-7, completing the bolt removal operation.

[0059] The storage box 3-7 on the right is used to receive bolts conveyed from the conveyor belt. The storage box 3-7 on the left is deflected by the material feeding rod 4-10, at which point the bolts can be emptied.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
