Description

Technical Field

[0001] This utility model relates to the field of internal grinding machine technology, specifically to an automatic loading and unloading device for internal grinding machines. Background Technology

[0002] Internal grinding machines are instruments used in the cutting process and equipment industry. These instruments are mainly used to grind the inner surface and end face of cylindrical, conical or other shaped generatrices.

[0003] A search of patent application number 202420196316.1 reveals that this utility model provides an automatic loading and unloading device for an internal grinding machine, relating to the field of parts processing technology. After automatic loading, no further adjustments are needed, allowing for direct processing. The automatic loading method ensures accurate positioning and fixation of the workpiece, avoiding errors that may arise from manual operation, thereby improving processing precision and stability. However, in this method, materials need to be moved onto the processing table, and after processing, they must be moved off, which not only increases the operator's workload but also leads to low production efficiency.

[0004] A search of patent application CN202323557532.9 reveals a universal loading and unloading robot for a fully automatic bearing internal grinding machine. This robot integrates the material gripper and the material arm, and modifies the material arm to an adjustable angle structure, allowing different models of bearing rings to share a single loading and unloading mechanism. This significantly improves the ease of model changeover and greatly reduces accessory costs. The gripper is equipped with fixing screw holes and adjusting screw holes, which are connected to the base via screws. The adjusting screw holes are elongated arc-shaped holes to allow for adjustable angles between the two grippers. During use, the material needs to be moved onto the processing table, and after processing, it also needs to be moved back down. This not only increases the operator's workload but also leads to low production efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic loading and unloading device for an internal grinding machine. The device automatically loads materials via a conveyor belt, positioning it on the processing table and in contact with two push plates. This increases the distance between the push plates, causing a crossbar to move, which in turn moves the upper gear rail, rotating the gears and causing the baffle to rotate from a horizontal to a vertical position. This automatically unloads the material from the placement slot without affecting the subsequent loading of new material. This automatic loading and unloading process reduces manual operation, improves work efficiency, and solves the problem of having to manually move materials onto the processing table and then unload them after processing, which increases the operator's workload and leads to low production efficiency.

[0010] Preferably, the sleeve is threadedly connected to the threaded rod, and a limiting rod is fixedly provided at the bottom of the lifting plate, and the number of limiting rods is four.

[0011] Preferably, the height of the inner grinding rod is equal to the height of the placement groove, and the top surface of the inner grinding rod and the bottom surface of the limiting rod are horizontally collinear.

[0012] Preferably, the processing table has a groove on the top surface of the end near the conveyor belt, one end of the conveyor belt extends into the groove, and anti-drop plates are provided on the top of both ends of the conveyor belt.

[0017] This invention provides an automatic loading and unloading device for an internal grinding machine. Compared with the prior art, it has the following advantages:

[0018] 1. This internal grinding machine uses an automatic loading and unloading device. The material is automatically loaded via a conveyor belt and positioned on the processing table, in contact with two push plates. This increases the distance between the two push plates, causing the crossbar to move and the upper gear rail to move simultaneously. This causes the gears to rotate, which in turn rotates the baffle from a horizontal to a vertical position, automatically unloading the material from the placement slot. This process does not affect the subsequent loading and unloading of new material into the placement slot, thus automatically completing the loading and unloading work, reducing manual operation and improving work efficiency.

[0019] 2. This internal grinding machine uses an automatic loading and unloading device. The downward movement of the lifting plate allows the internal grinding rod and the limiting rod to move downward simultaneously. When the internal grinding rod enters the placement slot, since the height of the internal grinding rod is equal to the height of the placement slot, the top surface of the internal grinding rod and the bottom surface of the limiting rod are horizontally collinear, which allows the limiting rod to contact the material, pressing the material and preventing it from moving, thus facilitating material processing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: an automatic loading and unloading device for an internal grinding machine, including a processing table 1, an automatic mechanism 2 on one side of the processing table 1, support rods 3 at the bottom of both ends of the processing table 1, a fixed plate 4 on the top of the processing table 1, a lifting plate 5 on one side of the fixed plate 4, and one end of the lifting plate 5 is slidably connected to the fixed plate 4, and an internal grinding rod 6 is provided at the bottom of the lifting plate 5.

[0028] The automatic mechanism 2 includes a conveyor belt 201. The top surface of the processing table 1 is provided with a placement groove 202. The bottom surface of the placement groove 202 is provided with a hole groove 203. The hole groove 203 is connected to the placement groove 202. The inside of the hole groove 203 is provided with a baffle 204. There are two baffles 204. One end of the two baffles 204 is provided with a gear 205. The bottom of the gear 205 is provided with a crossbar 206. One end of the crossbar 206 extends to the outside of the processing table 1. The end of the crossbar 206 away from the gear 205 is fixedly provided with a connecting rod 207. The top of one end of the conveyor belt 201 is provided with a push plate 208. The end of the push plate 208 near the gear 205 is inclined.

[0029] A groove 209 is provided on the top surface of the processing table 1 near the conveyor belt 201. One end of the conveyor belt 201 extends into the inside of the groove 209. Anti-drop plates 210 are provided on the top of both ends of the conveyor belt 201. The material can be automatically moved upward by the conveyor belt 201 and can be automatically transported to the processing table 1. During the transport process, the two anti-drop plates 210 prevent the material from falling.

[0030] The anti-drop plate 210 is in contact with the conveyor belt 201, and one end of the anti-drop plate 210 extends to the top of the processing table 1. The anti-drop plate 210 is fixedly connected to the processing table 1. The push plate 208 is in contact with the anti-drop plate 210, which can ensure that the distance between the two push plates 208 is increased.

[0031] A bracket 211 is fixedly installed on the top of the connecting rod 207. The connecting rod 207 is fixedly connected to the push plate 208 through the bracket 211. A toothed rail is installed on the top of the crossbar 206. The movement of the push plate 208 can move the bracket 211 and the connecting rod 207 together, and move the crossbar 206 fixedly connected to the connecting rod 207 together, and drive the toothed rail above to move.

[0032] A round rod 212 is provided on the front of the processing table 1. The round rod 212 passes through the connecting rod 207 and is in contact with the connecting rod 207. A connecting spring is provided around the outside of the connecting rod 207. The connecting rod 207 moves along the round rod 212 and can move linearly, compressing the connecting spring at the round rod 212 and causing the connecting spring to deform.

[0033] One end of the baffle 204 is arc-shaped, and one end of the gear 205 is fixedly equipped with a rotating rod 213. The rotating rod 213 is fixedly connected to the baffle 204, and one end of the rotating rod 213 is rotatably connected to the processing table 1. The rotation of the rotating rod 213 can cause the baffle 204 to rotate at the same time. The rotatable connection between the rotating rod 213 and the processing table 1 can prevent the rotating rod 213 and the baffle 204 from falling downwards.

[0034] Please see Figure 1 and 5 A vertical rod 7 is fixedly installed on the top of the inner grinding rod 6. A motor 8 is installed on the top of the vertical rod 7 and the top of the fixed plate 4. A sleeve 9 is installed on the top of the lifting plate 5. A threaded rod 10 is installed on the top of the sleeve 9 and is fixedly connected to the fixed plate 4. The sleeve 9 is threadedly connected to the threaded rod 10. When the motor 8 on the fixed plate 4 is turned on, the motor 8 drives the threaded rod 10 to rotate. Since the sleeve 9 is threadedly connected to the threaded rod 10, the rotating sleeve 9 can move downward through the threaded rod 10, which in turn causes the lifting plate 5 below to move downward, so that the limiting rod 11 and the motor 8 move downward together.

[0035] The bottom of the lifting plate 5 is fixedly equipped with four limiting rods 11. The height of the inner grinding rod 6 is equal to the height of the placement groove 202. The top surface of the inner grinding rod 6 and the bottom surface of the limiting rod 11 are horizontally collinear. When the inner grinding rod 6 enters the placement groove 202, the limiting rod 11 comes into contact with the material, which can press the material and prevent the material from moving, making it convenient to process the material.

[0036] During operation, materials are placed on conveyor belt 201, which automatically moves the materials upwards and transports them to processing table 1. The materials are then placed in placement slot 202, where baffles 204 in slot 203 support them and prevent them from falling. Next, motor 8 on fixed plate 4 is activated, causing threaded rod 10 to rotate. Since sleeve 9 is threadedly connected to threaded rod 10, the threaded rod 10 causes the rotating sleeve 9 to move downwards, thus lifting the lower part of the sleeve. The lowering plate 5 moves downward, causing the limiting rod 11 and the motor 8 to move downward together. As the motor 8 moves downward, the inner grinding rod 6 below it moves downward as well, allowing it to enter the placement groove 202 and contact the inner wall of the material. Since the top surface of the inner grinding rod 6 and the bottom surface of the limiting rod 11 are horizontally collinear, the motor 8 on the vertical rod 7 causes the vertical rod 7 and the inner grinding rod 6 below to rotate, thus processing the inner wall of the material. The material can then continue to be conveyed via the conveyor belt 201. During the conveying process, the rod can come into contact with the push plate 208, increasing the distance between the two push plates 208. Simultaneously, the bracket 211, fixedly connected to the push plate 208, moves, causing the connecting rod 207 below the bracket 211 to move. The round rod 212 passes through the connecting rod 207 and contacts it, allowing the connecting rod 207 to move along the round rod 212 in a linear motion. This compresses the connecting spring at the round rod 212, causing it to deform. The movement of the connecting rod 207 then... The movement of the crossbar 206 causes the toothed rail on the crossbar 206 to move simultaneously. Since the toothed rail meshes with the gear 205, the gear 205 rotates, which in turn drives the baffle 204 to rotate, making the baffle 204 rotate into a vertical state. This allows the material in the placement slot 202 to automatically enter the hole slot 203, enabling automatic material unloading. When the material moves to the processing table 1, it will separate from the push plate 208. The push plate 208 can be automatically reset by the connecting spring, so that the baffle 204 is in a horizontal state, which is convenient for subsequent operations.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
