Technical Field

[0001] This utility model relates to the field of surface grinding technology, and specifically to a CNC surface grinding machine with a positioning structure. Background Technology

[0002] CNC grinding machines are machine tools that use CNC technology to grind the surface of workpieces using grinding wheels. They are a product of the integration of information technology and mechanical manufacturing technology, representing the technological level and development trend of modern basic machinery. They are characterized by high precision, high efficiency, and a high degree of automation. CNC grinding machines come in a variety of types, including CNC surface grinders, CNC centerless grinders, and CNC internal and external cylindrical grinders, meeting the needs of different industries and workpieces. They play a vital role in fields such as automotive manufacturing, aerospace, gear processing, mold making, and national defense. For example, in the automotive industry, CNC grinding machines can be used to process automotive parts such as crankshafts, connecting rods, and camshafts. Furthermore, with the development of intelligent manufacturing and Industry 4.0, CNC grinding machines have further integrated technologies such as the Internet of Things, big data analysis, and artificial intelligence, achieving more intelligent production management and maintenance early warning functions. In short, CNC grinding machines are an indispensable and important piece of equipment in modern manufacturing.

[0003] Surface grinders are used to grind parts. Existing surface grinders usually require manual rotation of the screw to clamp and fix the parts. This is time-consuming and labor-intensive, and the clamping point is singular, resulting in poor clamping effect. As a result, the parts are very easy to shake during the grinding process, which can damage the parts and cause injury to the user.

[0004] Therefore, it is necessary to redesign and modify the surface grinder to effectively prevent the problems mentioned in the background technology. Utility Model Content

[0005] This invention provides a CNC surface grinder with a positioning structure, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a CNC surface grinder with a positioning structure, comprising: a grinder body, fixed tables fixedly connected to both sides of the top of the grinder body, a sliding plate provided on the inner side of the fixed table, the bottom of the sliding plate being fixedly connected to the top of the grinder body, a grinding disc provided on the top of the grinder body, a telescopic mechanism provided on the inner side of the sliding plate, and a clamping mechanism provided on the inner side of the fixed table. The telescopic mechanism is used to move and clamp the workpiece, and the clamping mechanism is used to efficiently fix the workpiece.

[0008] The above technical solution, through the setting of telescopic mechanism and clamping mechanism, facilitates the quick clamping and fixing of parts, and at the same time facilitates the buffering and protection of parts, improving the stability and safety of parts processing, and making it convenient for users.

[0009] Furthermore, the telescopic mechanism includes an electric actuator, which is fixedly installed on the inner side of the fixed platform. The output end of the electric actuator is fixedly connected to a sliding plate, and the bottom of the sliding plate is fixedly connected to a T-shaped block.

[0010] The above technical solution, through the setting of electric push rod and slide plate, makes it easy for the slide plate to move inward, driving the clamping mechanism to clamp, while the T-shaped block limits the slide plate, improving the stability of the slide plate movement.

[0011] Furthermore, each of the sliding plates has a groove on its inner side, and the top and bottom of the T-shaped block are fixedly installed with rollers that cooperate with the grooves. The number of rollers is several and they are evenly distributed in a straight line.

[0012] The above technical solution effectively reduces the friction between the T-block and the sliding plate by setting the rollers and grooves, improves the stability of the sliding plate, and extends the service life of the sliding plate and the T-block, making it easier for users to use.

[0013] Furthermore, the clamping mechanism includes positioning rods, a plurality of positioning rods being slidably connected inside the slide plate, a limit plate being fixedly connected to the outer side of the positioning rods, and a compression spring being sleeved on the surface of the positioning rods.

[0014] The above technical solution allows the positioning rod to slide inside the slide plate, providing an effective stroke for clamping and buffering parts, and the limiting plate facilitates efficient positioning of the positioning rod.

[0015] Furthermore, a clamping plate is fixedly connected to the inner side of the positioning rod, and a rubber pad is fixedly connected to the inner side of the clamping plate. The rubber pad is two centimeters in diameter and is used in conjunction with the grinding parts.

[0016] The above technical solution, through the setting of the clamping plate, facilitates efficient clamping and fixing of parts, while the setting of the rubber pad facilitates efficient protection of parts, improves the stability of parts grinding, and makes it convenient for users.

[0017] Furthermore, the bottom of the grinding disc is provided with partitions, the two sides of the partitions are fixedly connected to the inner side of the fixed platform, and the surface of the partitions is fixedly connected with reinforcing ribs.

[0018] The above technical solution, through the setting of the partition, makes it easy to prevent the grinding debris from flying outwards, avoiding injury to the user, and at the same time, it facilitates the cleaning of the grinding machine and improves the efficiency of the grinding machine.

[0019] The above-described solution of this utility model has at least the following beneficial effects:

[0020] 1. This utility model uses an electric actuator to move a sliding plate, which in turn moves the plate along the rollers and grooves at the top of the trapezoidal block. This movement drives the clamping mechanism to efficiently clamp and fix the parts, replacing the existing manual clamping and improving the stability of the parts grinding process.

[0021] 2. In this utility model, the positioning rod moves outward by contacting the part with the rubber pad, thereby compressing the compression spring. When the part is fully clamped and fixed, the spring is compressed to the maximum extent. By setting multiple positioning rods, the rubber pad can surround the part in a ring, increasing the clamping and fixing area of ​​the part, thereby improving the stability of clamping and fixing.

Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0029] like Figures 1 to 4 As shown, this utility model provides a CNC surface grinder with a positioning structure, including: a grinder body 1, fixed tables 2 fixedly connected to both sides of the top of the grinder body 1, a sliding plate 3 provided on the inner side of the fixed table 2, the bottom of the sliding plate 3 fixedly connected to the top of the grinder body 1, a grinding disc 4 provided on the top of the grinder body 1, a telescopic mechanism 5 provided on the inner side of the sliding plate 3, and a clamping mechanism 6 provided on the inner side of the fixed table 2. The telescopic mechanism 5 is used to move and clamp the parts, and the clamping mechanism 6 is used to efficiently fix the parts. The arrangement of the telescopic mechanism 5 and the clamping mechanism 6 facilitates the rapid clamping and fixing of the parts, and at the same time facilitates the buffering and protection of the parts, improving the stability and safety of the parts during processing.

[0030] like Figures 1 to 4 As shown, the telescopic mechanism 5 includes an electric push rod 51, which is fixedly installed on the inner side of the fixed platform 2. The output end of the electric push rod 51 is fixedly connected to a slide plate 52, and the bottom of the slide plate 52 is fixedly connected to a T-shaped block 53. The arrangement of the electric push rod 51 and the slide plate 52 facilitates the movement of the slide plate 52 inward, driving the clamping mechanism 6 to clamp it. At the same time, the T-shaped block 53 limits the movement of the slide plate 52, improving the stability of the movement of the slide plate 52. The inner sides of multiple sliding plates 3 are provided with sliding grooves 54. The top and bottom of the T-shaped block 53 are fixedly installed with rollers 55 that cooperate with the sliding grooves 54. There are several rollers 55, which are evenly distributed in a straight line. The arrangement of the rollers 55 and the sliding grooves 54 effectively reduces the friction between the T-shaped block 53 and the sliding plate 3, improves the stability of the sliding of the sliding plate 3, and also improves the service life of the sliding plate 3 and the T-shaped block 53.

[0031] In this embodiment of the utility model (working principle), when in use, the user activates the electric push rod 51, which drives the slide plate 52 to move, thereby causing the slide plate 52 to move along the roller 55 and the groove 54 at the top of the trapezoidal block, driving the clamping mechanism 6 to clamp and fix the parts efficiently, replacing the existing manual clamping, improving the stability of the parts grinding, and making it easier for the user to use.

[0032] like Figures 1 to 4As shown, the clamping mechanism 6 includes positioning rods 61, multiple positioning rods 61 are slidably connected inside the slide plate 52, and a limiting plate 62 is fixedly connected to the outer side of the positioning rods 61. A compression spring 63 is sleeved on the surface of the positioning rods 61. By sliding the positioning rods 61 inside the slide plate 52, an effective stroke can be provided for clamping and buffering the parts, and the limiting plate 62 facilitates efficient positioning of the positioning rods 61. A clamping plate 64 is fixedly connected to the inner side of the positioning rods 61, and a rubber pad 65 is fixedly connected to the inner side of the clamping plate 64. The rubber pad 65 is 2 cm thick and is used for grinding. The parts are used together, and the clamping plate 64 facilitates efficient clamping and fixing of the parts. At the same time, the rubber pad 65 provides efficient protection for the parts, improving the stability of grinding and making it easier for users to use. The bottom of the grinding disc 4 is provided with partitions 66, and the two sides of the partitions 66 are fixedly connected to the inner side of the fixed table 2. The surface of the partitions 66 is fixedly connected with reinforcing ribs 67. The partitions 66 prevent grinding debris from flying outwards, avoiding injury to the user, and also facilitate cleaning of the grinding machine, improving the efficiency of the grinding machine.

[0033] In this embodiment of the utility model, the positioning rod 61 moves outward by contacting the part with the rubber pad 65, thereby compressing the compression spring 63. When the part is fully clamped and fixed, the spring is compressed to the maximum extent. By setting multiple positioning rods 61, the rubber pad 65 can surround the part in a ring, increasing the area of ​​clamping and fixing the part, thereby improving the stability of clamping and fixing.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
