Description

Technical Field

[0001] This utility model relates to the field of grinding machine fixture technology, and in particular to a workpiece headstock rotary plate clamping device. Background Technology

[0002] When grinding a workpiece, a workpiece headstock is needed to fix the workpiece in place, ensuring its stability during processing. The workpiece headstock also provides necessary rotation or movement functions to meet different processing requirements. Traditionally, the workpiece headstock uses hydraulic cylinders or a combination of hydraulic cylinders and disc springs to clamp and fix the rotary plate holding the workpiece. However, this clamping method is complex and space-consuming, making it unsuitable for confined working environments. Utility Model Content

[0003] In order to solve the problems in related technologies, this utility model provides a workpiece headstock rotary plate clamping device that is suitable for working environments with limited space.

[0004] The technical solution is as follows:

[0005] This utility model provides a workpiece headstock rotary plate clamping device, including a base, a rotary table, an angle-adjusting cylinder, and a pressure plate assembly, wherein: the rotary table is rotatably connected to the upper surface of the base; the driving end of the angle-adjusting cylinder is connected to the rotary table; the pressure plate assembly is disposed on the upper surface of the base; the clamping end of the pressure plate assembly is disposed above the rotary table; the pressure plate assembly is configured to clamp the rotary table to the base; the angle-adjusting cylinder is configured to drive the rotary table to rotate on the base; the pressure plate assembly includes a pressure plate seat, a hydraulic oil circuit, and a clamping diaphragm, wherein: the pressure plate seat is disposed on the upper surface of the base; the clamping diaphragm is disposed at the clamping end of the pressure plate seat, and a hydraulic cavity is formed between the inner cavity of the clamping diaphragm and the pressure plate seat; the hydraulic oil circuit is disposed inside the pressure plate seat; the oil inlet end of the hydraulic oil circuit is connected to a hydraulic oil pipeline; the oil outlet end of the hydraulic oil circuit is connected to the hydraulic cavity.

[0006] The beneficial effect of this technical solution is that the upper surface of the rotary table is pressed by the pressure plate assembly, which, together with the base, clamps the rotary table and thus fixes the workpiece on the rotary table. Hydraulic pressure causes the diaphragm to bulge downwards, thereby pressing the rotary table. Compared to traditional hydraulic cylinders or combinations of hydraulic cylinders and disc springs, the diaphragm-based clamping solution has a simpler structure and occupies less space, making it suitable for use in confined working environments.

[0007] The workpiece headstock rotary plate clamping device provided by this utility model preferably further includes a resistance pad, which is disposed between the rotary table and the base; the resistance pad is located below the clamping end of the pressure plate assembly.

[0008] The workpiece headstock rotary plate clamping device provided by this utility model preferably further includes an angle-adjusting rotary shaft, which is mounted on the base and the rotating end of the angle-adjusting rotary shaft is connected to the rotary table.

[0009] The workpiece headstock rotary plate clamping device provided by this utility model preferably further includes a first limiting block and a second limiting block. The first limiting block and the second limiting block are respectively disposed at both ends of the rotation path of the rotary table. Both the first limiting block and the second limiting block are configured to limit the rotation range of the rotary table. Attached Figure Description

[0014] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0015] When grinding a workpiece, a workpiece headstock is needed to fix the workpiece in place, ensuring its stability during processing. The workpiece headstock also provides necessary rotation or movement functions to meet different processing requirements. Traditionally, the workpiece headstock uses hydraulic cylinders or a combination of hydraulic cylinders and disc springs to clamp and fix the rotary plate holding the workpiece. However, this clamping method is complex and space-consuming, making it unsuitable for confined working environments.

[0016] To address the aforementioned technical problems, this utility model provides a workpiece headstock rotary plate clamping device suitable for working environments with limited space.

[0017] like Figure 1-2 As shown:

[0018] A workpiece headstock rotary plate clamping device includes a base 1, a rotary table 2, an angle-adjusting cylinder 3, and a pressure plate assembly 4, wherein: the rotary table 2 is rotatably connected to the upper surface of the base 1; the driving end of the angle-adjusting cylinder 3 is connected to the rotary table 2; the pressure plate assembly 4 is disposed on the upper surface of the base 1; the clamping end of the pressure plate assembly 4 is disposed above the rotary table 2; the pressure plate assembly 4 is configured to clamp the rotary table 2 against the base 1; and the angle-adjusting cylinder 3 is configured to drive the rotary table 2. Rotates on base 1; the pressure plate assembly 4 includes a pressure plate seat 41, a hydraulic oil circuit 42, and a pressing diaphragm 43, wherein: the pressure plate seat 41 is located on the upper surface of base 1; the pressing diaphragm 43 is located at the pressing end of the pressure plate seat 41, and a hydraulic cavity is formed between the inner cavity of the pressing diaphragm 43 and the pressure plate seat 41; the hydraulic oil circuit 42 is located inside the pressure plate seat 41; the oil inlet of the hydraulic oil circuit 42 is connected to the hydraulic oil pipeline; the oil outlet of the hydraulic oil circuit 42 is connected to the hydraulic cavity.

[0019] In operation, the workpiece is first fixed on the rotary table 2. One side of the rotary table 2 is mounted on the base 1 via a rotating shaft. The drive end of the angle-adjusting cylinder 3 is connected to the other side of the rotary table 2. The angle-adjusting cylinder 3 pushes and pulls the rotary table 2, causing it to rotate around the rotating shaft, thus adjusting the workpiece's grinding position. After the position is adjusted, the hydraulic pump in the hydraulic oil line pressurizes the hydraulic oil line 42, increasing the oil pressure inside the hydraulic chamber. This pushes the inner cavity of the clamping diaphragm 43 outward, causing the clamping diaphragm 43 to press the rotary table 2 downward, pressing it firmly against the base 1 and locking it in place. At this point, the workpiece is stabilized and can be ground. The upper surface of the rotary table 2 is pressed by the pressure plate assembly 4, which, together with the base 1, clamps the rotary table 2, thus fixing the workpiece on the rotary table 2. Hydraulic pressure causes the diaphragm 43 to bulge downwards, thereby pressing the rotary table 2. Compared with the traditional hydraulic cylinder or hydraulic cylinder and disc spring combination, the pressing solution using the diaphragm 43 is simpler in structure and occupies less space, making it suitable for use in confined working environments.

[0020] In an optional embodiment, a resistance pad 5 is further included, which is disposed between the rotary table 2 and the base 1; the resistance pad 5 is located below the pressing end of the pressure plate assembly 4. The purpose of the resistance pad 5 is to increase the friction between the rotary table 2 and the base 1, so that the rotary table 2 is not easy to loosen when it is pressed; the resistance pad 5 may be made of rubber material.

[0021] In one optional embodiment, the system further includes an angle-adjusting rotary shaft 6, which is mounted on the base 1 and has its rotating end connected to the rotary table 2. The angle-adjusting rotary shaft 6 enables the rotary table 2 to rotate within a specific angle range. When the angle range is exceeded, the rotary table 2 can be limited to prevent the workpiece fixed on the rotary table 2 from moving out of the processing station.

[0022] In an optional embodiment, the system further includes a first limiting block 7 and a second limiting block 8, which are respectively located at both ends of the rotation path of the rotary table 2. Both the first limiting block 7 and the second limiting block 8 are configured to limit the rotation range of the rotary table 2. The first limiting block 7 can be set to a 0-degree limit, that is, to limit the starting position of the rotary table 2, and the second limiting block 8 can limit the maximum rotation angle of the rotary table 2.

[0023] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application filed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not claimed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this application are indicated by the appended claims.

[0024] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
