Description

Technical Field

[0001] This invention relates to the field of automotive connecting rod forging technology, and in particular to an automatic connecting rod loading box for an automatic feeding machine for a suspended flaw detector. Background Technology

[0002] In the rapid development of modern manufacturing, engine connecting rod forging plays a crucial role, involving the production of key equipment such as engines. However, with continuous technological advancements, the manufacturing industry faces increasingly higher demands for production efficiency and product quality. Against this backdrop, automated production has become an urgent need to reduce costs, improve efficiency, minimize human intervention, and ensure the production of high-quality products.

[0003] A key step in connecting rod forging is flaw detection, the primary purpose of which is to eliminate surface defects to ensure product quality and performance. However, traditional flaw detection processes present a number of challenges:

[0004] 1. Manual Operation: To date, the entire process from automatic weighing to flaw detection loading has relied on manual operation. This not only requires a large workforce but is also susceptible to human factors, including fatigue and human error.

[0005] 2. Complex actions: Flaw detection and feeding involve complex actions, such as reversing direction and lifting. This makes it costly to try to use robots to replace manual operation, and robots are usually slow and cannot meet the high production demand.

[0006] 3. Production costs: High labor costs and equipment maintenance expenses limit the manufacturing industry's potential to reduce production costs and improve competitiveness.

[0007] The applicant has developed a suspended automatic feeder for flaw detectors to automatically feed materials, which can effectively solve the above problems. However, with the continuous advancement of technology, the efficiency of flaw detectors has been greatly improved. Existing flaw detectors can perform flaw detection on batches of parts. In order to meet the quantity requirements of flaw detectors, there is an urgent need for an automatic bar-type material box for batch output. Summary of the Invention

[0008] In view of the above problems, the purpose of this invention is to provide an automatic feed box for engine connecting rods, which can achieve consistency in the output of multiple workpieces and can also be used in conjunction with a material distribution mechanism to improve conveying efficiency, thereby overcoming the shortcomings of the prior art.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An automatic connecting rod feeding box for engines includes: a material distribution output mechanism and a turning box. The material distribution output mechanism is installed on a material rack and is used to push the connecting rod from the conveyor chain into the turning box. The turning box is installed on the material rack and is located directly above the feed inlet of a flaw detector. The turning box is used to store a set of connecting rods received from the conveyor chain and to feed the set of connecting rods into the feed inlet of the flaw detector.

[0011] The material distribution mechanism includes: two sets of material-blocking cylinders mounted on the material rack and located on the conveyor chain; a material-blocking plate mounted on the piston rod of the material-blocking cylinder; and a material distribution cylinder mounted on the material rack and located on the side of the conveyor chain. The material-blocking plate falls from above the conveyor chain under the action of the material-blocking cylinder and prevents the connecting rod from continuing to travel on the conveyor chain. The number of material distribution cylinders corresponds to the number of material-blocking cylinders. The material distribution cylinder is used to push the connecting rod, which is blocked by the material-blocking cylinder, from the conveyor chain into the compartment of the material-turning box.

[0012] The material-turning box includes: a box body, a set of compartments located inside the box body, a material-discharging flip plate located below each compartment, a synchronous connecting rod for pushing the material-discharging flip plate, and a flip plate cylinder for pushing the synchronous connecting rod. The material-discharging flip plate is used to block the bottom outlet of the compartment. One side of the material-discharging flip plate is hinged to the box body. The end of the synchronous connecting rod corresponding to the number of material-discharging flip plates is hinged to the material-discharging flip plate. The piston rod of the flip plate cylinder pushes the synchronous connecting rod to drive the material-discharging flip plate to open or close.

[0013] As a preferred embodiment of the present invention, it further includes a material blocking mechanism, which includes: a guide cylinder mounted on the material rack and located directly above the flipping box; a guide plate bracket mounted on the piston rod of the guide cylinder; and a guide plate mounted on the guide plate bracket. The number of guide plates corresponds to the number of bins. The guide plates enter the bins under the drive of the guide cylinder and extend from the bottom outlet of the opened bins, guiding the connecting rod falling from the unloading flip plate to the inlet of the flaw detector.

[0014] As a preferred embodiment of the present invention, each set of the material blocking cylinders consists of two material blocking cylinders corresponding to the four compartments inside the material turning box.

[0015] The advantages and positive effects of this invention are:

[0016] 1. The material distribution mechanism of the present invention can not only achieve consistent material output during continuous material output, but also achieve simultaneous material output of multiple workpieces through the cooperation of the material blocking cylinder and the material distribution cylinder. When combined with the material turning box, it can meet the process requirements of the flaw detector, that is, the flaw detector can simultaneously perform flaw detection on multiple workpieces.

[0017] 2. The material output mechanism of the present invention uses a set of four material blocking cylinders to block the material. This not only adjusts the spacing between incoming parts to be aligned with the material rack at the outlet, but also ensures that the workpiece does not shift due to the contouring module on it.

[0018] 3. The compartments in the material turning box of the present invention, together with the material turning plate, can achieve the consistency of multiple workpieces being discharged, and can also be used with the material distribution mechanism to improve the conveying efficiency.

[0023] In the following description, numerous specific details are set forth for illustrative purposes and to provide a thorough understanding of one or more embodiments. However, it will be apparent that these embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

[0024] Example 1

[0025] See Figure 1-3This embodiment provides an automatic material distribution box for engine connecting rods, a material distribution output mechanism 1, and a material turnover box 2. The material distribution output mechanism 1 includes: a material blocking cylinder 101, a material blocking plate 102, and a material distribution cylinder 103. The four material blocking cylinders 101 are sequentially installed on the material rack 4 and located above the tail of the conveyor chain 5. The four material blocking plates 102 are respectively installed on the four material blocking cylinders 101. The four material blocking plates 102 are perpendicular to the end face of the conveyor chain 5. The spacing between the four material blocking plates 102 is the same as that between the material turnover box 2 and the material turnover box 2. The four compartment inlets correspond to each other. Four material equalization cylinders 103 are installed on the material rack 4 and located on the side of the conveyor chain 5. The positions of the four material equalization cylinders 103 correspond to the four baffle plates 102. Under the drive of the baffle cylinders 101, the four baffle plates 102 fall down from the top of the conveyor chain 5 from back to front and prevent the connecting rod from continuing to move on the conveyor chain 5. The four material equalization cylinders 103 push the connecting rod that is blocked by the baffle cylinders 101 from the conveyor chain 5 into the corresponding compartment 202 of the turning box 2. The material-turning box 2 includes: a box body 201, a set of four compartments 202 located inside the box body 201, a material-discharging flip plate 203 located below each compartment 202, a synchronous connecting rod 204 for pushing the material-discharging flip plate 203, and a flip plate cylinder 205 for pushing the synchronous connecting rod 204. The material-discharging flip plate 203 is used to block the bottom outlet of the compartment 202. One side of the material-discharging flip plate 203 is hinged to the box body 201. The end of the synchronous connecting rod 204 corresponding to the number of material-discharging flip plates 203 is hinged to the material-discharging flip plate 203. The piston rod of the flip plate cylinder 205 pushes the synchronous connecting rod 204 to drive the four material-discharging flip plates 203 to open or close.

[0026] The material blocking mechanism 3 in this embodiment includes: a guide cylinder 301 installed on the material rack 4 and located directly above the flipping box 2, a guide plate bracket installed on the piston rod of the guide cylinder 301, and a guide plate 302 installed on the guide plate bracket. The number of the four guide plates 302 corresponds to the number of the four compartments 202. The guide plates 302 enter the compartment 202 under the drive of the guide cylinder 301 and extend out from the bottom outlet of the opened compartment 202, guiding the connecting rod falling from the unloading flip plate 203 to the inlet of the flaw detector.

[0027] In this embodiment, multiple cylinders are controlled by photoelectric switches used for detecting workpieces.

[0028] Working principle: The connecting rod is conveyed to the flaw detector position via the conveyor chain 5. The material distribution output mechanism 1 pushes the connecting rod from the conveyor chain 5 into the turning box 2. A set of four baffles 102 of the material distribution output mechanism 1, driven by the baffle cylinders 101, fall sequentially from back to front above the conveyor chain 5, preventing the connecting rod from continuing its journey. The four material distribution cylinders 103 push the connecting rod, blocked by the baffle cylinders 101, from the conveyor chain 5 into the corresponding compartment 202 of the turning box 2. The turning box 2 stores a set of connecting rods received from the conveyor chain 5 and sends the set of connecting rods into the flaw detector inlet. The four compartments 202 of the turning box 2 can simultaneously output four connecting rods. The baffle mechanism 3 guides the connecting rods falling from the discharge flaps into the flaw detector inlet.

[0029] The specific process includes the following steps:

[0030] Step S1: Use conveyor chain 5 to transport the connecting rod to the flaw detector position;

[0031] Step S2: The material distribution mechanism 1 is used to position and transport the four connecting rods on the conveyor chain 5 into the turning box 2. The four connecting rods on the conveyor chain 5 are positioned by four parallel material blocking cylinders 101. First, the material blocking cylinder 101 at the last end of the conveyor chain 5 is activated to block and position the first connecting rod. Then, the second to last material blocking cylinder 101 is activated to block and position the connecting rod. Then, the third to last material blocking cylinder 101 is activated to block and position the connecting rod. Finally, the fourth to last material blocking cylinder 101 is activated to block and position the connecting rod, thus completing the overall positioning of the material distribution mechanism 1. The four material distribution cylinders 103 are used to push the positioned connecting rods from the conveyor chain 5 into the four compartments 202 of the turning box 2 in sequence. The material distribution cylinders 103 and the material blocking cylinders 101 act synchronously. After the action is completed, the material blocking cylinders 101 and the material distribution cylinders 103 return to their initial positions.

[0032] Step S3: Use the tipping box 2 to store a set of four connecting rods received from the conveyor chain 5 and send a set of connecting rods into the feed port of the flaw detector. After all four compartments 202 of the tipping box 2 receive the connecting rods, the tipping cylinder 205 drives the discharge tipping plate 203 to fall and tilt to 45° through the synchronous connecting rod 204. The connecting rods located in the compartments 202 slide off the discharge tipping plate 203. After the action is completed, the tipping cylinder 205 returns to the initial position.

[0033] Step S4: The material blocking mechanism 3 guides the connecting rod that falls from the discharge flap 203 into the feed inlet of the flaw detector. At the same time as the flap cylinder 205 is opened, the guide cylinder 301 is opened. The guide cylinder 301 extends from the bottom outlet of the compartment 202 through the guide plate 302 and blocks part of the bottom opening of the discharge flap 203, so that the connecting rod slides from the discharge flap 203, hits the guide plate 302 and falls into the feed inlet of the flaw detector. After the action is completed, the guide cylinder returns to the initial position.

[0034] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
