Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, specifically to a grinding test machine. Background Technology

[0002] In the field of machining, processing cylindrical workpieces often requires multiple steps, such as cutting and grinding, to meet the requirements for precision and surface quality. Traditionally, the cutting and grinding processes for cylindrical workpieces are performed separately, which not only consumes a significant amount of time but also increases processing costs.

[0003] In existing related technologies, a common practice is to first use specialized cutting equipment to cut the cylindrical workpiece. For example, a machine tool cuts along a specific direction while the workpiece rotates to change its shape and size. After cutting, the workpiece is transferred to a grinding device, where grinding wheels or sandpaper are used to polish the surface to improve its smoothness.

[0004] However, this traditional machining method, which separates cutting and grinding, has many drawbacks. On the one hand, the separation of processes leads to a longer machining cycle, as each process change requires additional time for equipment adjustment, workpiece clamping and positioning. On the other hand, multiple workpiece clamping can easily introduce positioning errors, affecting the final machining accuracy of the workpiece.

[0005] Therefore, the above problems urgently need to be solved. Utility Model Content

[0006] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a grinding test machine. By integrating the clamping and rotating assembly, the cutting assembly and the grinding assembly on the same frame operating table, the cutting assembly can move along the X, Y and Z directions to cut the workpiece. The grinding assembly uses a pair of grinding belts set above and below to grind the workpiece synchronously. Moreover, the cutting assembly and the grinding assembly can work at the same time, thereby shortening the processing cycle, reducing costs and improving the processing accuracy of cylindrical workpieces.

[0007] Technical Solution: This utility model provides a grinding testing machine comprising: a frame, a clamping and rotating assembly, a cutting assembly, and a grinding assembly. The frame is equipped with an operating table. The clamping and rotating assembly is located on the operating table and is used to clamp the workpiece and drive it to rotate along its axis. The cutting assembly is located on the operating table and is used to cut along the axial and radial directions of the workpiece during rotation. The cutting assembly moves along the X, Y, and Z directions. The grinding assembly is located on the operating table and includes a pair of grinding belts arranged vertically along the Z direction. The workpiece is clamped between the pair of grinding belts, and the grinding belts are used to grind a section of the workpiece clamped within the grinding belts. The cutting assembly and the grinding assembly work simultaneously to complete the workpiece processing synchronously. The clamping and rotating assembly can firmly hold the workpiece and drive it to rotate along its own axis, providing a stable rotational foundation for subsequent cutting and grinding. The cutting assembly can move in the X, Y, and Z directions, and can accurately cut the workpiece axially and radially while it is rotating, meeting different processing requirements. The grinding assembly uses a pair of grinding belts set at the top and bottom to clamp the workpiece in the middle, which can grind specific parts of the workpiece and can work simultaneously with the cutting assembly to achieve synchronization of the processing.

[0008] Furthermore, in a grinding test machine of this application, the clamping and rotating assembly includes a first support frame and a first cylinder. The first support frame is mounted on an operating table, and the first cylinder is mounted on the first support frame. The cylinder body of the first cylinder moves along the first support frame in the Z direction. A first rotary motor is mounted on the cylinder body of the first cylinder, and a gripper is mounted on the output end of the first rotary motor. The gripper is used to clamp the end of the workpiece, and the rotation axis of the workpiece is set along the X direction. The cylinder body of the first cylinder can move along the first support frame in the Z direction, which allows the gripper to be positioned according to workpieces of different heights, adapting to diverse workpiece sizes. The gripper, mounted on the output end of the first rotary motor, can firmly clamp the end of the workpiece, ensuring that the workpiece will not shake or fall off during rotation, providing a stable foundation for subsequent processing. The first rotary motor can drive the gripper and the clamped workpiece to rotate along the rotation axis in the X direction, meeting the rotation requirements of cutting and grinding.

[0009] Furthermore, in a grinding test machine of this application, the cutting assembly includes a first guide rail, a second guide rail, a moving stage, a first motor, a second cylinder, a third cylinder, and a second rotary motor. The first and second guide rails are arranged parallel to each other along the X direction. The moving stage is mounted on and perpendicular to the first and second guide rails. The first motor drives the moving stage to move along the first guide rail in the X direction, and simultaneously moves along the second guide rail in the X direction. The second cylinder is mounted on the moving stage, and a third cylinder is mounted on its output end. The second cylinder drives the third cylinder to move along the Y direction. The output end of the third cylinder is mounted on the second rotary motor, which drives the second rotary motor to move along the Z direction. A cutting head is provided at the end of the second rotary motor. The second rotary motor is arranged along the Y direction, and its cutting head is perpendicular to the workpiece. By adjusting the first motor, the second cylinder, and the third cylinder, the position of the second rotary motor is changed, so that the cutting head contacts the workpiece and cuts the workpiece. The first motor drives the moving stage, which moves along the X direction using the first and second guide rails; the second cylinder drives the third cylinder to move in the Y direction; and the third cylinder drives the second rotary motor to move in the Z direction. This allows the cutting head to be flexibly positioned in three-dimensional space. The second rotary motor drives the cutting head to rotate, and the cutting head is perpendicular to the workpiece. This allows for efficient cutting of the workpiece when the cutting head contacts it. The multiple driving components work together, and the position of the second rotary motor can be precisely changed by adjusting the parameters of the first motor, the second cylinder, and the third cylinder, thereby accurately controlling the contact position and cutting depth between the cutting head and the workpiece.

[0010] Furthermore, in a grinding test machine of this application, the grinding assembly further includes a base plate mounted on an operating table. The base plate is provided with a pair of mounting brackets and a pair of third rotary motors. Each mounting bracket, third rotary motor, and grinding belt corresponds to a specific component. The third rotary motors are mounted on the mounting brackets and are connected to the grinding belts via a drive mechanism. The base plate, mounted on the operating table, provides a stable support foundation for the entire grinding assembly, ensuring that the assembly does not shake during grinding. The pair of third rotary motors, each mounted on a corresponding mounting bracket and connected to the grinding belts via a drive mechanism, provide power to the grinding belts, enabling them to rotate at high speed and grind the workpiece.

[0011] Furthermore, in a grinding test machine of this application, the mounting frame includes a frame and a crossbeam. The third rotary motor is mounted on the crossbeam, and the crossbeam is adjustable and movable along the frame in the Z direction. The crossbeam's adjustable movement along the frame in the Z direction allows for height adjustment of the third rotary motor mounted on the crossbeam and the grinding belt connected thereto. By changing the height of the grinding belt, cylindrical workpieces of different diameters can be accommodated, ensuring that the workpiece is accurately clamped between the upper and lower grinding belts, providing a suitable position for the grinding operation.

[0012] Furthermore, in a grinding test machine of this application, a pair of support platforms are provided on the operating table. The grinding assembly is positioned between the pair of support platforms in the X direction. An arc-shaped groove is provided at the upper end of each support platform, and the workpiece is placed within the arc-shaped groove and rotates within it. The support platforms provide additional support points for cylindrical workpieces. During the grinding process, especially for longer workpieces, relying solely on the grippers of the rotating assembly may cause the workpiece to wobble or deform during rotation. The arc-shaped groove of the support platform is adapted to the outer surface of the workpiece, stably supporting it and ensuring a stable rotational state throughout the processing. The arc-shaped groove also guides the workpiece, ensuring it rotates along a predetermined axis and preventing deviation during rotation. This helps ensure the accuracy of cutting and grinding operations, resulting in workpieces that meet design requirements. When mounting the workpiece onto the grinding test machine, the arc-shaped groove of the support platform can serve as a positioning reference. Operators can first place the workpiece in the arc-shaped groove, and then clamp it with the gripper of the rotating clamping component, which makes it easier and more accurate to install and position the workpiece.

[0013] Furthermore, in one grinding test machine of this application, the cutting head is frustoconical. When the cutting head begins to contact the workpiece, due to its frustoconical structure, it gradually cuts into the workpiece from the smaller end, achieving progressive cutting. This cutting method can reduce the sudden application of cutting force, reduce the impact on the workpiece and equipment, and make the cutting process smoother.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0015] 1. The grinding test machine of this utility model integrates the clamping and rotating assembly, the cutting assembly and the grinding assembly on the same frame operating table, and the cutting assembly and the grinding assembly can work simultaneously, avoiding the time waste caused by the separation of cutting and grinding processes in traditional processing, greatly shortening the processing cycle, while reducing additional operations such as equipment adjustment and workpiece transfer, reducing labor and time costs, and effectively improving processing efficiency and reducing costs.

[0016] 2. The grinding test machine of this utility model enhances the equipment's versatility for workpieces of different specifications by incorporating a clamping and rotating gripper that can be adjusted along the Z direction, a cutting component that can move flexibly in the X, Y, and Z directions, a height-adjustable grinding belt mounting bracket, a support platform with an arc groove, and a frustum-shaped cutting head. This avoids positioning errors introduced by multiple workpiece clamping, reduces impact and vibration during the cutting process, and ensures stable rotation of the workpiece during processing, thereby significantly improving the processing accuracy of cylindrical workpieces.

[0027] The clamping and rotating assembly 3 includes a first support frame 31, a first cylinder 32, a first rotary motor 33, and a gripper 34. The first support frame 31 is mounted on the operating table 2, and the first cylinder 32 is mounted on the first support frame 31, allowing its cylinder body to move along the Z-axis. The first rotary motor 33 is mounted on the cylinder body of the first cylinder 32, and the gripper 34 is connected to the output end of the first rotary motor 33 to firmly clamp one end of the workpiece, ensuring that the workpiece can rotate stably in the X-axis direction.

[0028] Cutting assembly 4 consists of a first guide rail 41, a second guide rail 42, a moving stage 43, a first motor 44, a second cylinder 45, a third cylinder 46, and a second rotary motor 47. The first guide rail 41 and the second guide rail 42 are arranged parallel to each other along the X-axis. The moving stage 43 is located on these two guide rails and is driven by the first motor 44 to move along the X-axis. The second cylinder 45 and the third cylinder 46 are responsible for displacement adjustment in the Y-axis and Z-axis directions, respectively. The end of the second rotary motor 47 is equipped with a frustoconical cutting head 471, which can precisely perform cutting operations on the workpiece.

[0029] Grinding assembly 5 includes a base plate 52, a pair of mounting brackets 53, a pair of third rotary motors 54, and a pair of grinding belts 51. The base plate 52 is mounted on the operating table 2, providing a stable foundation for the grinding assembly. Each mounting bracket 53 and third rotary motor 54 corresponds to one grinding belt 51, which are arranged vertically to clamp a portion of the workpiece for grinding. Furthermore, the crossbar 532 of the mounting bracket 53 can be adjusted and moved along the frame 531 in the Z direction to accommodate workpieces of different sizes.

[0030] Support platform 21: The operating table 2 is also equipped with a pair of support platforms 21. These support platforms 21 are provided with arc-shaped grooves that are adapted to the outer surface of the workpiece to stably support long workpieces and prevent them from shaking or shifting during processing.

[0031] Workflow

[0032] In practical use, the cylindrical workpiece to be processed is first placed between the support platforms 21 on the operating table 2, and between a pair of grinding belts 51, and one end is firmly clamped using the gripper 34. Then, the first rotary motor 33 is started to rotate the workpiece along its axis. Simultaneously, the position of the cutting assembly 4 is adjusted as needed so that its cutting head 471 contacts the workpiece and begins the cutting operation. While cutting, the grinding assembly 5 also works synchronously, grinding another part of the workpiece via the grinding belts 51. Because the cutting assembly 4 and the grinding assembly 5 can operate simultaneously, the processing cycle is greatly shortened, and work efficiency is improved.
