Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically a feeding device for a spline shaft grinding machine. Background Technology

[0002] As an indispensable key transmission component in many mechanical devices, the machining accuracy and quality of spline shafts have a significant impact on the overall performance of the equipment. Grinding machines, as one of the main equipment for achieving high-precision machining of spline shafts, rely heavily on the performance of their feeding devices, which directly affects machining efficiency and the stability of machining quality. Traditional spline shaft grinding machine feeding devices often employ manual feeding or simple mechanical pushing methods. Manual feeding is not only labor-intensive but also makes it difficult to ensure the consistency of feeding speed and accuracy, easily leading to inaccurate feeding and causing deviations in the spline shaft machining position, thus affecting machining quality and potentially damaging the grinding machine tools. On the other hand, some simple mechanical pushing devices are not conducive to achieving automated continuous production, resulting in low production efficiency and failing to meet the demands of modern manufacturing for large-volume, high-precision spline shaft machining. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a feeding device for a spline shaft grinding machine. It solves the problem that traditional spline shaft grinding machine feeding devices mostly use manual feeding or simple mechanical pushing methods. Manual feeding is not only labor-intensive, but also difficult to ensure the consistency of feeding speed and accuracy. Inaccurate feeding can easily lead to deviations in the spline shaft machining position, which in turn affects the machining quality and may even damage the grinding machine tools. On the other hand, some simple mechanical pushing devices are not conducive to achieving automated continuous production, resulting in low production efficiency and failing to meet the needs of modern manufacturing for large-volume, high-precision spline shaft machining.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a spline shaft grinding machine, comprising a pushing chamber, a support block inside the pushing chamber, a pushing frame fixedly connected to one side of the support block, a pushing groove formed between the inner walls of the pushing frame, a reciprocating pushing mechanism inside the pushing chamber, the reciprocating pushing mechanism comprising a rotating rod rotatably connected between the inner walls of the pushing chamber, a control motor fixedly installed at the top of the pushing chamber, the output end of the control motor connected to the top of the rotating rod, the other end of the rotating rod penetrating the bottom of the pushing chamber and fixedly connected to a drive rod, the other end of the drive rod rotatably connected to a transmission rod, the length of the transmission rod being greater than that of the drive rod, a connecting rod rotatably connected to the end of the transmission rod away from the drive rod, and the top of the connecting rod being connected to the center position of the bottom of the support block.

[0005] As a further embodiment of this utility model: two limiting slide rods are fixedly connected to both sides of the support block, the limiting slide rods are designed in the form of an I-beam, and two limiting slide rails are symmetrically fixedly connected between the inner walls of the push chamber, the two limiting slide rods slide in the two limiting slide rails respectively, and the support block slides in the push chamber through the limiting slide rods and the limiting slide rails.

[0006] As a further embodiment of this utility model: a feeding bin is fixedly installed on the top of the pushing bin. The feeding bin is a vertical design. The spline shaft body is stacked inside the feeding bin. The bottom outlet of the feeding bin corresponds to the initial position of the pushing frame.

[0007] As a further embodiment of this utility model: a feeding bin is fixedly connected below the pushing bin, the pushing bin is of an inclined design, and the position of the pushing bin corresponds to the pushing position of the pushing frame.

[0008] As a further embodiment of this utility model: a through groove is provided at the bottom of the pushing chamber, and the connecting rod in the reciprocating pushing mechanism passes through the through groove.

[0009] As a further embodiment of this utility model: four support frames are fixedly connected to the outer wall of the push chamber, and the four support frames are respectively distributed at the four corners of the push chamber.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The feeding device of this spline shaft grinding machine, by setting a reciprocating pushing mechanism, controls the output end of the motor to drive the rotating rod in the reciprocating pushing mechanism to rotate. The rotation of the rotating rod further drives the drive rod to rotate. The rotation of the drive rod is converted into a reciprocating push-pull action, causing one end of the transmission rod to swing and the other end to rotate at the bottom of the connecting rod. The traction connecting rod slides back and forth along the through groove, thereby causing the support block to drive the pushing frame to move back and forth in the pushing chamber. In this way, the consistency of the feeding speed of the spline shaft body can be ensured. At the same time, the pushing frequency and speed can be flexibly adjusted according to actual production needs, improving the automation level of feeding and production efficiency.

[0011] 2. The feeding device of this spline shaft grinding machine, by setting up a feeding bin and a pushing bin, stacks the spline shaft body to be processed in the feeding bin. Under the action of gravity, the spline shaft body automatically falls into the pushing groove in the pushing frame. After the pushing frame pushes the spline shaft body to the top opening of the feeding bin, the spline shaft body automatically falls into the feeding bin under the action of gravity and is automatically fed along the inclined surface of the feeding bin. This operation method not only simplifies the feeding process, but also ensures that the spline shaft body can smoothly enter the subsequent processing steps, improves the automation and reliability of feeding, reduces the intensity of manual labor, and improves work efficiency.

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-5 As shown, this utility model provides a technical solution: a feeding device for a splined shaft grinding machine, including a feeding chamber 1. Four support frames 12 are fixedly connected to the outer wall of the feeding chamber 1, and the four support frames 12 are distributed at the four corners of the feeding chamber 1. A support block 2 is provided inside the feeding chamber 1. Two limiting slide rods 6 are fixedly connected to both sides of the support block 2. The limiting slide rods 6 are I-shaped. Two limiting slide rails 7 are symmetrically fixedly connected between the inner walls of the feeding chamber 1. The two limiting slide rods 6 slide in the two limiting slide rails 7 respectively. The support block 2 slides within the feeding chamber 1 through the limiting slide rods 6 and the limiting slide rails 7. Through the cooperation between the limiting slide rods 6 and the limiting slide rails 7, the support block 2 drives the limiting slide rods 6 on both sides to slide in the two limiting slide rails 7 respectively, thus enabling... The movement of the support block 2 is well limited, ensuring that the support block 2 slides smoothly and linearly in the push chamber 1, and preventing the support block 2 from deviating or shaking during the movement. This ensures that the push frame 3 can accurately push the spline shaft body 9 to the designated position, improving the accuracy and reliability of the feeding. The push frame 3 is fixedly connected to one side of the support block 2. The push frame 3 has a push groove 4 between the inner walls of the push frame 3. The push groove 4 is used to support and fix the spline shaft body 9, ensuring that it will not shift during the push process in the push chamber 1. This ensures that the spline shaft body 9 can smoothly enter the subsequent processing steps. At the same time, the push groove 4 cooperates with the reciprocating push mechanism 5 to continuously push the spline shaft body 9 at the same rate, thereby improving the reliability of the feeding. The push chamber 1 is equipped with a reciprocating push mechanism 5, which includes a rotating rod 501 rotatably connected to the inner wall of the push chamber 1. A control motor 502 is fixedly installed at the top of the push chamber 1, and the output end of the control motor 502 is connected to the top of the rotating rod 501. The other end of the rotating rod 501 passes through the bottom of the push chamber 1 and is fixedly connected to a drive rod 503. The other end of the drive rod 503 is rotatably connected to a transmission rod 504, the length of which is greater than that of the drive rod 503. The end of the transmission rod 504 away from the drive rod 503 is rotatably connected to a connecting rod 505, and the top of the connecting rod 505 is connected to the bottom of the support block 2. The components are connected at the center. Because a reciprocating pushing mechanism 5 is provided, the rotating rod 501 in the reciprocating pushing mechanism 5 drives the driving rod 503 to rotate. The driving rod 503 pushes and pulls the transmission rod 504, so that the transmission rod 504 drives the support block 2 to perform reciprocating linear motion in the pushing chamber 1 through the connecting rod 505. This can ensure the consistency of the feeding speed and accuracy of the spline shaft body 9. At the same time, by controlling the start and stop of the motor 502, the pushing frequency and speed can be flexibly adjusted according to the actual production needs, which improves the automation level of feeding and production efficiency. A through groove 11 is opened at the bottom of the pushing chamber 1, and the connecting rod 505 in the reciprocating pushing mechanism 5 passes through the through groove 11. A feeding bin 8 is fixedly installed on the top of the push chamber 1. The feeding bin 8 is a vertical design, and spline shaft bodies 9 are stacked inside the feeding bin 8. The bottom outlet of the feeding bin 8 corresponds to the initial position of the push frame 3. Because of the feeding bin 8, the spline shaft bodies 9 to be processed are stacked and placed inside the feeding bin 8. Under the action of gravity, the spline shaft bodies 9 will automatically fall into the push slot 4 in the push frame 3. This feeding method eliminates the need for manual placement of spline shaft bodies 9 one by one, improving work efficiency. At the same time, the vertical design ensures the smooth falling of the spline shaft bodies 9 and avoids damage to the spline shafts. If the key shaft body 9 gets stuck or blocked during the feeding process, a feeding bin 10 is fixedly connected to the bottom of the push bin 1. The push bin 1 has an inclined design, and its position corresponds to the push position of the push frame 3. Because of the push bin 1 and its inclined design, after the push frame 3 pushes the spline shaft body 9 to the top opening of the feeding bin 10, the spline shaft body 9 can automatically fall into the feeding bin 10 under the action of gravity. This simplifies the feeding process, ensures that the spline shaft body 9 can smoothly enter the subsequent processing steps, and improves the automation level of feeding.

[0015] The working principle of this utility model is as follows: When using this device, the spline shaft body 9 to be processed is first stacked in the feed bin 8. The spline shaft body 9 at the bottom of the feed bin 8 will fall into the push groove 4 in the push frame 3. The control motor 502 is started, and its output end drives the rotating rod 501 to rotate. The rotation of the rotating rod 501 will drive the drive rod 503 to rotate. The rotation of the drive rod 503 will be converted into reciprocating push and pull, causing one end of the transmission rod 504 to swing. At the same time, the other end of the transmission rod 504 will rotate at the bottom end of the connecting rod 505, and pull the connecting rod 505 to slide back and forth along the through groove 11, thereby causing the support block 2 to reciprocate horizontally in the push bin 1. When the support block 2 moves, it will cause the two limiting slide rods 6 on both sides to slide in the two limiting slide rails 7 respectively, ensuring that the support block 2 can slide smoothly in the push chamber 1. The support block 2 drives the push frame 3 to move, and the push frame 3 drives the spline shaft body 9 in the push groove 4 to the top opening of the feeding chamber 10. Under the action of gravity, the spline shaft body 9 automatically falls into the feeding chamber 10 and automatically feeds along the inclined surface of the feeding chamber 10. When the push frame 3 returns to the initial position, the spline shaft body 9 located at the bottom in the feed chamber 8 falls into the push frame 3 again. The above steps are continuously repeated to realize the automatic feeding of the spline shaft body 9.
