Description
Technical Field
[0001] The utility model relates to the technical field of internal and external cylindrical grinding machines, and more specifically, to a feeding structure for an internal and external cylindrical grinding machine. Background Technique
[0002] An internal and external cylindrical grinding machine is a precision machine tool used for machining cylindrical workpieces, mainly for grinding the outer and inner surfaces of the workpieces to achieve the required dimensional accuracy, shape accuracy, and surface roughness.
[0003] When the existing grinding machine mechanism is in use, it mainly relies on manual operation. Workers need to carry and place the workpieces to be processed onto the grinding machine one by one. The manual feeding speed is slow. Especially for large-scale production, the labor intensity of workers is high, and it is difficult to meet the requirements of high-efficiency production. Frequent repetitive actions not only consume time but also easily cause worker fatigue, further reducing the feeding speed. The position accuracy of manually placing the workpieces is greatly affected by human factors. Different workers may have different placement positions and angles during operation, which will affect the accuracy consistency of grinding machine processing. Even the same worker may make operation mistakes after working for a long time, resulting in inaccurate workpiece positions. When workers approach the grinding machine for feeding operations, they face the risk of being injured by rotating grinding tools, transmission components, etc. At the same time, carrying heavy workpieces may also cause work-related injuries such as muscle strains and sprains to workers, presenting certain safety hazards.
[0004] The utility model can effectively improve the processing efficiency of the grinding machine and enhance the safety of the device during use. Content of the Utility Model
[0005] The purpose of the utility model is to solve the technical problems raised in the above background technique and provide a feeding structure for an internal and external cylindrical grinding machine.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A feeding structure for an internal and external cylindrical grinding machine, comprising: a machine body, a bracket is fixedly installed at the upper end of the machine body, a moving group is arranged at the inner top end of the bracket, and a feeding group is arranged on one side of the machine body;
[0007] The moving group includes a hydraulic rod, a connecting plate, two connecting blocks, and a clamping block. The connecting plate is installed at the bottom of the hydraulic rod. The two connecting blocks are installed below the connecting plate. Both of the two connecting blocks are connected to the clamping block below. A bayonet is opened at the lower end of the clamping block;
[0008] The feeding group includes a support plate, a feeding hopper, and a baffle. The support plate is fixedly installed inside the bracket. One end of the feeding hopper is fixed to one side of the support plate. A support block is fixedly installed at one end of the support plate.
[0009] Further preferred solution: A chute is provided inside the bracket. A motor is installed inside the chute, and a screw rod is installed at the output end of the motor. One end of the screw rod is embedded in the inner wall of the chute, and the screw rod is movably connected to the bracket.
[0010] Further preferred solution: A slider is nested on the outer surface of the screw rod. The slider is connected to the upper end of the hydraulic rod by a bolt, and the screw rod is threadedly connected to the slider.
[0011] Further preferred solution: Drums are embedded at both ends of the opening of the bayonet. Grooves are provided on the inner wall of the opening of the bayonet. The drums are embedded inside the grooves, and the drums are movably connected to the grooves.
[0012] Further preferred solution: A rotating rod penetrates through the inside of the drum. Both ends of the rotating rod are fixedly installed on the inner wall of the groove, and the outermost end of the drum protrudes beyond the outer end of the groove. The rotating rod is movably connected to the drum.
[0013] Further preferred solution: The feed hopper is inclined. A feed inlet is provided between the baffle and the support plate, and the lowest end of the baffle is connected to the feed inlet.
[0014] Further preferred solution: The position of the support block corresponds to the position of the clamping block, and the top of the support block is in a concave shape.
[0015] Beneficial effects:
[0016] 1. By providing a feeding group, the workpiece is received by the feed hopper. The inclined feed hopper can use gravity to make the workpiece slide automatically towards the lower place, facilitating the workpiece to smoothly enter the subsequent processing link from the feed hopper. The inclined feed hopper can accommodate more workpieces, improving the feeding efficiency. The main function of the baffle is to guide and limit the workpiece, ensuring that the workpiece can accurately enter the next operation through the feed inlet. The workpiece can smoothly enter the feed inlet under the guidance of the baffle during the sliding process, ensuring that the workpiece can be accurately clamped. At the same time, the support block is used to limit the clamped workpiece, making the workpiece more stable on the top of the support block, thereby improving the working efficiency and stability of the feeding structure;
[0017] 2. By providing a moving group, when the workpiece rolls to the upper end of the support block, the motor is used to drive the screw rod to rotate, thereby driving the moving group to move. The hydraulic rod is used to drive the clamping block to descend, so that the drum of the clamping block contacts the workpiece. The clamping block continues to descend, and the bayonet is in full contact with the workpiece and clamps the workpiece. Finally, the hydraulic rod contracts, driving the connecting plate, connecting block and clamping block to move upward, lifting and transporting the clamped workpiece to the processing area of the internal and external cylindrical grinder for processing, improving the working efficiency and stability, and making the device more flexible and convenient to use;
[0018] 3. In summary, for the loading structure used in internal and external cylindrical grinding machines, by setting up structures such as a feeding group and a moving group, the workpiece loading becomes more convenient. The feeding group is used to store and limit the workpiece. Through the cooperation of the baffle plate and the support plate, the workpiece passes through the feeding port and falls onto the upper end of the support block for limitation. Then, the hydraulic rod and the clamping block of the moving group cooperate with each other, so that the roller of the clamping block contacts the workpiece. The clamping block continues to descend, and the bayonet completely contacts and clamps the workpiece. Finally, the hydraulic rod is used to lift the clamped workpiece and transport it to the processing area of the internal and external cylindrical grinding machine for processing, improving work efficiency and stability, and making the device more flexible and convenient to use.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached Figures 1-6 drawings in the embodiments of the present invention.
[0027] Please refer to Figure 1-6, in the embodiment of the present utility model, a feeding structure for an internal and external cylindrical grinder includes: a machine body 1, a bracket 2 is fixedly installed at the upper end of the machine body 1, a moving group 3 is arranged at the top end inside the bracket 2, and a feeding group 4 is arranged on one side of the machine body 1; the moving group 3 includes a hydraulic rod 301, a connecting plate 302, two connecting blocks 303 and a clamping block 304, the connecting plate 302 is installed at the bottom of the hydraulic rod 301, the two connecting blocks 303 are installed below the connecting plate 302, and both of the two connecting blocks 303 are connected to the clamping block 304 below, and a bayonet 305 is opened at the lower end of the clamping block 304; the feeding group 4 includes a support plate 401, a feeding hopper 402 and a baffle 403, the support plate 401 is fixedly installed inside the bracket 2, one end of the feeding hopper 402 is fixed on one side of the support plate 401, and a support block 404 is fixedly installed at one end of the support plate 401; the device is composed of the machine body 1, the bracket 2, the moving group 3 and the feeding group 4. The machine body 1 serves as a basic support component, the bracket 2 is fixed at the upper end of the machine body 1 to provide an installation position for the moving group 3, the feeding group 4 is arranged on one side of the machine body 1 and is responsible for conveying the workpiece to be processed to a specific position, and the moving group 3 is responsible for clamping and transporting the workpiece from the feeding group 4 to the processing area of the internal and external cylindrical grinder. The hydraulic rod 301 serves as the power source of the moving group 3, and controls the up and down movement of the connecting plate 302 through its telescopic movement. When the hydraulic rod 301 extends, it pushes the connecting plate 302 downward to approach the workpiece on the feeding group 4. When the hydraulic rod 301 contracts, it drives the connecting plate 302 upward to lift and transport the clamped workpiece to the processing position. The connecting plate 302 plays a role in connecting the hydraulic rod 301 and the connecting blocks 303. The connecting plate 302 transmits the power of the hydraulic rod 301 to the connecting blocks 303, enabling the connecting blocks 303 to move up and down along with the movement of the hydraulic rod 301. The connecting blocks 303 are connected to the connecting plate 302 on one hand and the clamping block 304 on the other hand, playing a role in connecting and transmitting force. The clamping block 304 is used to clamp the workpiece. When the hydraulic rod 301 pushes the connecting plate 302 downward, the clamping block 304 also descends, the bayonet 305 contacts and clamps the workpiece, and then the hydraulic rod 301 contracts to lift and transport the workpiece. The support plate 401 provides support for the feeding hopper 402 and the support block 404. The support plate 401 ensures the stability of the feeding hopper 402 and the support block 404, enabling them to work properly. The feeding hopper 402 is used to store and convey the workpiece to be processed, and the workpiece can automatically slide to a specific position through the inclination angle of the feeding hopper 402 and wait to be clamped by the moving group 3. The baffle 403 plays a role in preventing the workpiece from accidentally sliding out of the feeding hopper 402 or restricting the movement direction of the workpiece. The support block 404 plays an auxiliary positioning role during the workpiece conveying process, enabling the workpiece to fall onto the upper end of the support block 404 by its own gravity, and then the moving group 3 clamps the workpiece and moves the workpiece to the processing place for processing, making the device more flexible and convenient to use.
[0028] In the embodiment of the present utility model, a chute 201 is provided inside the bracket 2. A motor 202 is installed inside the chute 201, and a screw rod 203 is installed at the output end of the motor 202. One end of the screw rod 203 is embedded in the inner wall of the chute 201, and the screw rod 203 is movably connected to the bracket 2. Among them, a slider 204 is nested on the outer surface of the screw rod 203. The slider 204 is connected to the upper end of the hydraulic rod 301 by a bolt, and the screw rod 203 is threadedly connected to the slider 204. The setting of the chute 201 makes the movement of these components more stable and directional, ensuring the accuracy and reliability of the entire feeding structure during operation. The motor 202, as a power source, provides power for the rotation of the screw rod 203. The motor 202 can transmit power to the screw rod 203 to make it rotate. Due to the effect of the thread, the slider 204 will move along the axial direction of the screw rod 203. Specifically, according to the rotation direction of the screw rod 203, the slider 204 can move left and right on the screw rod 203, so that the hydraulic rod 301 connected to the slider 204 can be adjusted in position within a certain range. The feeding structure adjustment mechanism that drives the screw rod 203 to rotate by the motor 202, and then drives the slider 204 and the hydraulic rod 301 to move, improves the flexibility and adaptability of the feeding structure.
[0029] In the embodiment of the present utility model, rollers 306 are embedded at both ends of the opening of the bayonet 305. Grooves 307 are provided on the inner wall of the opening of the bayonet 305. The rollers 306 are embedded inside the grooves 307, and the rollers 306 are movably connected to the grooves 307. Among them, a rotating rod 308 is provided through the inside of the roller 306. Both ends of the rotating rod 308 are fixedly installed on the inner wall of the groove 307, and the outermost end of the roller 306 protrudes beyond the outer end of the groove 307. The rotating rod 308 is movably connected to the roller 306. The bayonet 305 is a part for clamping workpieces, and the setting of the rollers 306 plays an important auxiliary role in the process of clamping workpieces. The grooves 307 provide an installation space for the rollers 306, enabling the rollers 306 to rotate freely therein. After the rollers 306 are embedded in the grooves 307, on the one hand, it can ensure that they will not easily fall off or shift during the clamping of workpieces, and on the other hand, it also makes the structure of the bayonet 305 more compact and stable. The rotating rod 308 plays a role in supporting the roller 306, enabling the roller 306 to rotate around the rotating rod 308. When the clamping block 304 clamps the workpiece, the workpiece contacts the roller 306. Since the roller 306 can rotate, it can reduce the friction between the workpiece and the bayonet 305, making the clamping process smoother, avoiding scratches or damage to the surface of the workpiece. At the same time, the outermost end of the roller 306 protrudes beyond the outer end of the groove 307, ensuring that the workpiece can first contact the roller 306 when entering the bayonet 305, giving full play to the anti-friction effect of the roller 306. The roller 306 improves the efficiency and safety of clamping workpieces, reduces damage to the surface of the workpiece, and makes the clamping block 304 more convenient and flexible when clamping workpieces.
[0030] In the embodiment of the present utility model, the feed hopper 402 is inclined. There is a feed inlet 405 provided between the baffle 403 and the support plate 401. The lowest end of the baffle 403 is connected to the feed inlet 405. Among them, the position of the support block 404 corresponds to the position of the clamping block 304. The top of the support block 404 is in a "concave" shape. The inclined feed hopper 402 can utilize gravity to make the workpiece slide automatically towards the lower place, facilitating the workpiece to smoothly enter the subsequent processing link from the feed hopper 402. Secondly, the inclined structure can save space and make the entire feeding structure more compact. Moreover, the inclined feed hopper 402 can accommodate more workpieces, improving the feeding efficiency. The main function of the baffle 403 is to guide and restrict the workpiece to ensure that the workpiece can accurately enter the next operation through the feed inlet 405. The lowest end of the baffle 403 is connected to the feed inlet 405, so that the workpiece can smoothly enter the feed inlet 405 under the guidance of the baffle 403 during the sliding process. The size and position of the feed inlet 405 are carefully designed to cooperate with the operation of the clamping block 304 to ensure that the workpiece can be accurately clamped. When the clamping block 304 descends to clamp the workpiece, the support block 404 can provide support for the workpiece at a suitable position to ensure the stability and accuracy of the clamping process. The top of the support block 404 is in a "concave" shape, which can better adapt to the shape of the workpiece, making the workpiece more stable on the support block 404, not easy to roll or shift, and effectively preventing the workpiece from rolling down, making the device more stable during use. On the other hand, when the clamping block 304 clamps the workpiece, the "concave"-shaped support block 404 can provide a better operating space for the clamping block 304, making the clamping more convenient and fast. The feed inlet 405 and the support block 404 with a specific shape and position cooperate together to improve the working efficiency and stability of the feeding structure.
[0031] Working principle: First, place the workpiece to be processed in the inclined feed hopper 402. Since the feed hopper 402 is inclined, the workpiece automatically slides downward under the action of gravity. The baffle 403 guides and restricts the workpiece to ensure that the workpiece can accurately slide through the feed port 405 onto the support block 404. The top of the support block 404 is in a "concave" shape, which can better adapt to the shape of the workpiece and enable the workpiece to stay stably on the support block 404 waiting to be clamped. Then, the motor 202 starts, driving the screw 203 to rotate. Since the screw 203 is threadedly connected to the slider 204, and the slider 204 is nested on the outer surface of the screw 203 and connected to the upper end of the hydraulic rod 301 by a bolt, the rotation of the screw 203 will cause the slider 204 to move along the axial direction of the screw 203. According to the rotation direction of the screw 203, the slider 204 can move left and right on the screw 203, thereby adjusting the position of the hydraulic rod 301 to make it correspond to the position of the workpiece to be clamped. Then, the hydraulic rod 301 extends, pushing the connecting plate 302 downward. The connecting block 303 and the clamping block 304 below the connecting plate 302 also move downward accordingly. When the clamping opening 305 at the lower end of the clamping block 304 approaches the workpiece, the workpiece first contacts the rollers 306 at both ends of the opening of the clamping opening 305. Since the rollers 306 can rotate freely around the rotating rod 308 and the outermost end of the roller 306 protrudes beyond the outer end of the groove 307, the friction between the workpiece and the rollers 306 is greatly reduced, making the clamping process smoother and avoiding scratching or damaging the surface of the workpiece. The clamping block 304 continues to descend, and the clamping opening 305 is in full contact with the workpiece and clamps the workpiece. Finally, the hydraulic rod 301 contracts, driving the connecting plate 302, the connecting block 303, and the clamping block 304 to move upward, lifting and transporting the clamped workpiece to the processing area of the internal and external cylindrical grinder for processing. The entire loading process realizes automatic loading through the coordinated work of the machine body 1, the bracket 2, the moving group 3, and the feeding group 4, improving work efficiency and stability, and making the device more flexible and convenient to use.
