Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical processing technology and relates to a clamping and positioning machine for grinding and polishing equipment. Background Technology
[0002] Grinding and polishing equipment is an industrial tool used to treat the surfaces of metal and non-metal workpieces through mechanical grinding, lapping, or polishing. It is widely used in machinery manufacturing, electronics and communications, and automotive parts industries. Its purpose is to remove burrs, oxide layers, machining marks, and other defects from the workpiece surface, improving surface smoothness, precision, and aesthetics to meet the surface quality requirements of various industries.
[0003] In the field of grinding and polishing equipment, workpiece clamping and positioning are key factors affecting processing quality and efficiency. Traditional processing equipment typically uses a fixed-spacing clamping structure, resulting in poor compatibility with workpieces of different sizes. Frequent disassembly and adjustment of the clamping device are required when changing workpieces, severely impacting processing efficiency.
[0004] Meanwhile, existing clamping structures mostly fix the workpiece in a single posture, and can only process the exposed local surface during the processing. If it is necessary to process complex structures such as inclined surfaces, curved surfaces or multi-directional surfaces, it is necessary to manually flip the workpiece or rely on multi-station switching equipment. The operation is cumbersome and easily introduces errors due to repeated positioning, resulting in a decrease in processing accuracy. Utility Model Content
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A clamping positioner for grinding and polishing equipment, applied in grinding and polishing equipment, includes: a processing frame, on which a set of laterally extending adjustable slide rail modules are provided, and a set of clamping modules are respectively installed at both ends of the adjustable slide rail modules;
[0007] One side of the clamping module is an active clamping module, and the other side of the clamping module is a passive clamping module.
[0008] The active clamping module includes: a first clamping frame, an active clamping arm rotatably mounted on the first clamping frame, and a rotary drive motor for driving the active clamping arm to rotate;
[0009] The driven clamping module includes: a second clamping frame and a driven clamping arm rotatably mounted on the second clamping frame.
[0010] As a further embodiment of this utility model: a support bearing seat is also installed on the first clamping frame and the second clamping frame; the active clamping arm and the driven clamping arm are rotatably mounted on the first clamping frame and the second clamping frame through the support bearing seat.
[0011] As a further embodiment of this utility model: the second clamping frame of the driven clamping module is also provided with a set of clamping and adjusting slide rails in the same direction of extension as the adjusting slide rail module; the clamping and adjusting slide rails are equipped with clamping and adjusting slide blocks by sliders, and the driven clamping arm is installed on the clamping and adjusting slide blocks.
[0012] Furthermore, the second clamping frame is also equipped with a clamping and adjusting cylinder that drives it to move on the clamping and adjusting slide rail.
[0013] As a further embodiment of this utility model, a dustproof bellows cover is provided on the adjustable slide rail module to cover it.
[0014] As a further embodiment of this utility model, both the active clamping module and the driven clamping module are covered with dustproof covers.
[0015] The beneficial effects of this utility model are as follows: By cooperating with the adjustable slide rail module and the active and driven clamping modules, the clamping position can be automatically adjusted according to the length of the workpiece, quickly adapting to the clamping effect of workpieces of different specifications. Furthermore, by driving the workpiece to rotate, different processing surfaces of the workpiece can be sequentially entered into the processing station, reducing the processing steps of manual material transfer and meeting multi-directional processing needs. It can also construct a multi-axis processing system by linking the rotation axis of the active clamping arm with the XYZ axes of the grinding and polishing equipment. This enables the processing of special structures such as inclined surfaces and curved surfaces, reduces processing blind spots, improves the uniformity and accuracy of surface treatment, and greatly expands the process application range of the equipment.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0023] In the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0024] This utility model provides a reference. Figures 1-4 In this embodiment of the present invention, a clamping positioner for a grinding and polishing processing equipment is applied in the grinding and polishing processing equipment, comprising: a processing frame 1, on which a set of laterally extending adjustable slide rail modules 11 are provided, and a set of clamping modules are respectively installed at both ends of the adjustable slide rail modules 11; during processing, the workpiece is clamped by the two sets of clamping modules; the two sets of clamping modules can adjust their positions on the adjustable slide rail modules 11 according to the length of the clamped workpiece;
[0025] Of the two clamping modules: one side is the active clamping module 3, and the other side is the passive clamping module 2;
[0026] The active clamping module 3 includes: a first clamping frame 31, an active clamping arm 34 rotatably mounted on the first clamping frame 31, and a rotary drive motor 32 for driving the active clamping arm 34 to rotate.
[0027] The driven clamping module 2 includes: a second clamping frame 21 and a driven clamping arm 22 rotatably mounted on the second clamping frame 21;
[0028] During processing, the active clamping module 3 and the driven clamping module 2 move towards the center position, and the workpiece is clamped by the cooperation of the active clamping arm 34 and the driven clamping arm 22. According to the processing requirements, the active clamping arm 34 is driven to rotate by the rotary drive motor 32, thereby realizing the rotation of the workpiece. The driven clamping arm 22 is a non-powered structure. When rotating, it relies on the passive rotation of the workpiece friction to ensure that the workpiece remains stable during the rotation process.
[0029] By rotating the workpiece, different machining surfaces of the workpiece can be sequentially entered into the machining station to meet multi-directional machining needs. Alternatively, the active clamping arm 34 can be used as a rotation axis to work in conjunction with the XYZ axes of the grinding and polishing equipment to build a multi-axis machining system. This enables the machining of special structures such as inclined surfaces and curved surfaces, reduces blind spots in machining, improves the uniformity and precision of surface treatment, and greatly expands the range of technological applications of the equipment.
[0030] Furthermore, support bearing seats 33 are also installed on the first clamping frame 31 and the second clamping frame 21; the active clamping arm 34 and the driven clamping arm 22 are rotatably mounted on the first clamping frame 31 and the second clamping frame 21 via the support bearing seats 33. The configuration of the support bearing seats 33 provides structural support force to the clamping arms, enabling them to stably clamp the workpiece; significantly improving the operational stability and accuracy of the clamping module.
[0031] Furthermore, the second clamping frame 21 of the driven clamping module 2 is also provided with a set of clamping and adjusting slide rails 25 extending in the same direction as the adjusting slide rail module 11; the clamping and adjusting slide rail 25 is mounted with a clamping and adjusting slide block 24 via a slider, and the driven clamping arm 22 is mounted on the clamping and adjusting slide block 24.
[0032] Furthermore, the second clamping frame 21 is also equipped with a clamping adjustment cylinder 26 that drives it to move on the clamping adjustment slide rail 25;
[0033] During processing, the active clamping module 3 and the driven clamping module 2 are pre-moved to a specific processing position, and the active clamping arm 34 and the driven clamping arm 22 form a clamping distance that enables product clamping. Then, the driven clamping arm 22 is moved backward by the clamping adjustment cylinder 26 so that the workpiece can enter the clamping distance. Then, the driven clamping arm 22 is moved forward by the clamping adjustment cylinder 26 to complete the workpiece clamping operation. This allows the clamping operation to be achieved without adjusting the processing position of the active clamping module 3 and the driven clamping module 2 during continuous processing, improving the convenience of continuous processing.
[0034] Furthermore, the adjustable slide rail module 11 is provided with a dustproof bellows cover 11 to cover it; this is used to protect the adjustable slide rail module 11 and improve processing stability.
[0035] Furthermore, both the active clamping module 3 and the driven clamping module 2 are covered with dustproof covers 4, which protect the working parts other than the active clamping arm 34 and the driven clamping arm 22. Together with the dustproof bellows cover 11, they protect the overall structure and improve the stability of the machining process.
[0036] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
