Description

Technical Field

[0001] This utility model relates to the field of CNC grinding machines, specifically a positioning and pushing device for CNC grinding machines. Background Technology

[0002] A grinding machine is a machine tool that uses grinding wheels to grind the surface of a workpiece. When grinding a workpiece, a pusher device is needed to position and push the workpiece.

[0003] According to the published patent CN221676859U, a positioning and pushing device for a CNC grinding machine includes a base plate. Two slide rails are fixedly connected to the top of the base plate, and cavities are provided on both sides of the base plate. A pushing mechanism is installed on the base plate. When the operator starts the motor, the motor drives the threaded rod at the output end to rotate via a coupling. When the threaded rod rotates, it drives a movable plate connected to the outer thread to move back and forth, pushing the workpiece above. Because the movable plate is slidably connected to the outer side of the two slide rails, and no cavities are provided on the inner side of the slide rails, the problem of debris remaining on the inner side of the slide groove during pushing processing is avoided, preventing blockage and thus improving the efficiency of the device's movement.

[0004] In traditional CNC grinding machine positioning and pushing devices, to prevent machining debris residue, the threaded rod is usually placed on the outside of the device. By keeping the threaded rod away from the inside of the slide, it avoids the difficulty in cleaning debris that falls into the slide during the pushing process, thus affecting the normal operation and service life of the device. However, although this positioning and pushing method avoids debris residue in the slide, a large amount of debris generated during the machining process still accumulates on the surface of the device platform. Operators have to frequently stop their work to clean the debris on the device platform, which not only increases the labor intensity of the workers but also reduces production efficiency, making the entire machining process less convenient and efficient. At the same time, during the positioning and pushing process of the workpiece, the part of the clamping plate that contacts the workpiece is also prone to debris accumulation. When debris is attached to the surface of the clamping plate, the friction and contact stability between it and the workpiece are affected. When the clamping plate is used to position and clamp the workpiece, problems such as insecure clamping and workpiece shaking are likely to occur, resulting in poor clamping stability, which in turn affects the machining accuracy and quality of the workpiece and causes unnecessary losses in production. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, adapt to practical needs, and provide a positioning and pushing device for CNC grinding machines. This addresses the problem that in traditional CNC grinding machine positioning and pushing devices, to prevent machining debris residue, the threaded rod is usually placed on the outside of the device. By keeping the threaded rod away from the inside of the slide groove, it avoids the difficulty in cleaning debris that falls into the slide groove during the pushing process, thus affecting the normal operation and service life of the device. However, although this positioning and pushing method avoids debris residue in the slide groove, a large amount of debris generated during processing still accumulates on the surface of the device platform, forcing operators to frequently stop the machine. The work of cleaning debris from the equipment platform not only increases the labor intensity of the workers but also reduces production efficiency, making the entire processing flow less convenient and efficient. At the same time, during the processing, positioning, and pushing of the workpiece, debris easily accumulates at the contact points between the clamping plate and the workpiece. When debris adheres to the surface of the clamping plate, the friction and contact stability between it and the workpiece are affected. When the clamping plate positions and clamps the workpiece, problems such as insecure clamping and workpiece shaking are likely to occur, resulting in poor clamping stability. This, in turn, affects the processing accuracy and quality of the workpiece, causing unnecessary losses to production.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a positioning and pushing device for a CNC grinding machine is designed, including a device platform. A set of first fixing plates and second fixing plates are respectively arranged on both sides of the device platform. There are two first fixing plates and two fixing plates in each set, which are respectively fixed to the front and rear ends of both sides of the device platform. A first threaded rod is arranged between the two first fixing plates. A first moving block passes through the outside of the first threaded rod. A support plate is provided on the top of the first moving block. A dual-axis motor is installed on both sides of the top of the support plate. The output shaft of the dual-axis motor is connected to a cleaning component for cleaning debris on the surface of the device platform. A first telescopic cylinder is installed in the middle of the top of the support plate. The piston rod at the top of the first telescopic cylinder is connected to the positioning and pushing component.

[0007] Preferably, the cleaning assembly includes a cleaning brush, which is connected to the bottom output shaft of a dual-axis motor passing through the support plate, and a blower fan is mounted on the top output shaft of the dual-axis motor.

[0008] Preferably, the positioning and pushing assembly includes a concave plate, one end of which is equipped with a first drive motor. The output shaft of the first drive motor extends into the concave plate and is connected to a second threaded rod inside the concave plate via a coupling.

[0009] Preferably, the two outer ends of the second threaded rod are provided with opposite threads, and the opposite threads are respectively connected to the threaded holes that pass through the clamping plates at both ends of the second threaded rod.

[0010] Preferably, the clamping plate has a circular hole on its side, and an electromagnetic ring is installed inside the circular hole.

[0011] Preferably, the bottom of the concave plate has a square hole, and a mesh is installed inside the square hole.

[0012] Preferably, a limiting rod is fixed between the two second fixed plates, and a second movable block passes through the outside of the limiting rod.

[0013] Preferably, both the first and second movable blocks are provided with a circular groove at their top, and a second telescopic cylinder is installed inside the circular groove. A support plate is fixed to the piston rod at the top of the second telescopic cylinder.

[0014] Preferably, one end of the first threaded rod passes through the first fixed plate and is connected to a second drive motor, and the second drive motor is mounted on one end of the first fixed plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model combines a dual-axis motor, cleaning brushes, and blower blades. During equipment operation, when the first threaded rod moves the support plate, the dual-axis motor moves synchronously. While the positioning and pushing operation is underway, multiple rotating cleaning brushes clean debris from the platform surface. Simultaneously, the rotation of the dual-axis motor drives the blower blades to rotate as well. After the clamping plate has finished clamping the workpiece, it can be adjusted to the position of the blower blades. The airflow generated by the rotating blower blades blows away debris adhering to the surface of the clamping plate, thus preventing residual debris and ensuring the stability of the workpiece clamping is maintained. This solves the problem of debris buildup during processing. Debris accumulates on the surface of the equipment platform, forcing workers to frequently stop their work to clean it. This not only increases the workload but also reduces production efficiency, making the entire processing flow less convenient and efficient. Furthermore, during the workpiece positioning and pushing process, debris easily accumulates at the contact points between the clamping plate and the workpiece. When debris adheres to the surface of the clamping plate, the friction and contact stability between it and the workpiece are affected. This can lead to problems such as insecure clamping and workpiece wobbling, resulting in poor clamping stability and consequently affecting the workpiece's processing accuracy and quality, causing unnecessary losses in production.

[0017] 2. This utility model, through the combination of a support plate, a first telescopic cylinder, and a positioning and pushing assembly, not only allows for the clamping and pushing of workpieces using the clamping plate, but also features circular holes on the surface of the clamping plate, each containing an electromagnetic ring. In actual operation, especially before positioning and pushing, when processing cylindrical workpieces, the operator can sequentially pass the cylindrical workpiece through multiple electromagnetic rings on the clamping plate. At this time, the electromagnetic rings can adsorb the metal debris attached to the surface of the cylindrical workpiece. In this way, it effectively avoids residual metal debris on the surface of the cylindrical workpiece, thereby solving the problem of poor stability during clamping due to debris.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] Example 1: A positioning and feeding device for a CNC grinding machine, see [link / reference] Figures 1 to 3The device includes a platform 1. A set of first fixing plates 101 and second fixing plates 106 are respectively provided on both sides of the platform 1. There are two first fixing plates 101 and two fixing plates 106 in each set, which are fixed to the front and rear ends of both sides of the platform 1 respectively. A first threaded rod 103 is provided between the two first fixing plates 101. A first moving block 104 passes through the outside of the first threaded rod 103. A support plate 2 is provided on the top of the first moving block 104. One end of the first threaded rod 103 passes through the first fixing plate 101 and is connected to a second drive motor 102. The second drive motor 102 is installed on one end of the first fixing plate 101. A limit rod 107 is fixed between the two second fixing plates 106. A second moving block 105 passes through the outside of the limit rod 107. Dual-axis motors 201 are installed on both sides of the top of the support plate 2.

[0024] When positioning and pushing the workpiece, the second drive motor 102 is started. The second drive motor 102 will drive the first threaded rod 103 to rotate. The first threaded rod 103 will drive the first moving block 104 to move. The first moving block 104 will drive the support plate 2 to move. When the first threaded rod 103 drives the support plate 2 to move, the dual-axis motor 201 can be driven to move simultaneously.

[0025] For details, see Figure 2 The output shaft of the dual-axis motor 201 is connected to a cleaning assembly for cleaning debris from the surface of the device platform 1. The cleaning assembly includes a cleaning brush 203, which is connected to the bottom output shaft of the dual-axis motor 201 that passes through the support plate 2. A blower blade 204 is mounted on the top output shaft of the dual-axis motor 201.

[0026] In the positioning and pushing device of a traditional CNC grinding machine, to prevent machining debris from remaining, the threaded rod is usually placed on the outside of the device, away from the inside of the slide. While this can prevent debris from falling into the inside of the slide during pushing and thus prevent the device from being affected by the difficulty in cleaning the debris inside the slide, the debris generated during the machining process will accumulate in large quantities on the surface of the device platform. The operator has to frequently stop work to clean up these debris, which not only greatly increases the labor intensity but also reduces the production efficiency, making it difficult to achieve a convenient and efficient machining process.

[0027] To address the aforementioned issues, this application activates the dual-axis motor 201 as it moves with related components. While the positioning and pushing operation proceeds normally, the dual-axis motor 201 drives multiple cleaning brushes 203 to rotate. These brushes thoroughly clean debris from the surface of the device platform 1, effectively solving the problem of debris accumulation on the platform surface in traditional devices. Simultaneously, the rotation of the dual-axis motor 201 also drives the top blower blades 204 to rotate. After the clamping plate 303 has finished clamping the workpiece, it can be adjusted to the position of the blower blades 204. The airflow generated by the rotating blower blades 204 blows away debris adhering to the surface of the clamping plate 303, preventing residual debris and thus preventing reduced stability of the workpiece clamping due to debris, ensuring smooth processing and high-quality machining.

[0028] Further, see Figure 1 and Figure 2 A first telescopic cylinder 205 is installed at the top center of the support plate 2. The piston rod at the top of the first telescopic cylinder 205 is connected to a positioning and pushing assembly. The positioning and pushing assembly includes a concave plate 3. A first drive motor 301 is installed at one end of the concave plate 3. The output shaft of the first drive motor 301 extends into the concave plate 3 and is connected to a second threaded rod 302 inside the concave plate 3 through a coupling. A square hole is opened at the bottom of the concave plate 3, and a partition net 202 is installed inside the square hole.

[0029] When performing workpiece clamping operations, the workpiece to be processed must first be securely placed in the middle area formed by the two clamping plates 303. Then, the first drive motor 301 is started, and the first drive motor 301 starts to run and drives the second threaded rod 302 connected to it to rotate. Since the second threaded rod 302 has threads in opposite directions on its outside, the two clamping plates 303 move in opposite directions under the action of the threads, and gradually approach the workpiece until the workpiece is clamped. Moreover, after the initial clamping of the workpiece is completed, if it is necessary to adjust the height of the workpiece, simply start the first telescopic cylinder 205. The first telescopic cylinder 205 will drive the entire concave plate 3 and the clamped workpiece to move in the vertical direction, thereby adjusting the height of the workpiece to meet different processing scenarios and process requirements.

[0030] It is worth noting that, see Figure 1 The clamping plate 303 has a circular hole 304 on its side, and an electromagnetic ring 305 is installed inside the circular hole 304.

[0031] When the operator passes the cylindrical workpiece sequentially through the electromagnetic rings 305 set on multiple clamping plates 303, the electromagnetic rings 305 are energized. According to the principle of electromagnetic induction, a magnetic field is generated around the energized electromagnetic rings 305. The metal debris attached to the surface of the cylindrical workpiece is mostly magnetic. Under the action of the magnetic field generated by the electromagnetic rings 305, these metal debris are attracted by the magnetic force and are tightly adsorbed onto the surface of the electromagnetic rings 305. As the cylindrical workpiece passes through each electromagnetic ring 305, the metal debris attached to its surface is gradually and completely adsorbed and removed, keeping the surface of the cylindrical workpiece clean. This avoids problems such as unevenness and increased roughness of the workpiece surface caused by residual metal debris. In the subsequent clamping process, the clamping plates 303 can fully contact the clean surface of the cylindrical workpiece, increasing the friction and effectively solving the problem of poor clamping stability caused by debris. This ensures the accuracy and reliability of the positioning and pushing operation and improves the quality and efficiency of the entire processing flow.

[0032] It is worth noting that, see Figure 3 Both the first moving block 104 and the second moving block are provided with a circular groove 108 at the top. A second telescopic cylinder 109 is installed inside the circular groove 108. A support plate 2 is fixed to the piston rod at the top of the second telescopic cylinder 109.

[0033] The first moving block 104 and the second moving block 105 are both provided with a second telescopic cylinder 109 in the circular groove 108 at the top. By controlling the second telescopic cylinder 109, the support plate 2 and the cleaning disc connected below it can be lifted together, so that the cleaning disc is completely separated from the surface of the device platform 1, avoiding direct contact between the cleaning disc and the surface of the device platform 1. During the rotation of the cleaning disc, a large frictional resistance is generated, which adversely affects the speed of the blower blade 204 connected to the output shaft of the other end of the dual-axis motor 201, reducing the blowing effect.

[0034] It should be noted that the multiple second telescopic cylinders 109 in this application are synchronously controlled by a synchronization controller, the model of which is MCT-116.

[0035] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
