For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0028] Embodiment one:

[0029] Based on the prior art existing at present, when fixing the workpiece, the movable seat needs to be manually moved to the appropriate position, and then fixed by an additional limiting device, so that the device cannot quickly and accurately adjust the clamping position and fixing of the workpiece, and when clamping and fixing the out-of-plane part, the air pump needs to be used to inflate the air bag to extrude the limiting block to be extruded and attached to the out-of-plane part. However, when the air pump fails, the out-of-plane part is easy to lose the fixing effect, thereby causing the out-of-plane part to be loose, which is not conducive to the processing and fixing of the workpiece. Please refer to Figures 1-5 The utility model provides a technical scheme: a numerical control lathe processing frock clamp, including mounting seat 1, mounting seat 1 top fixedly connected with fixed frame 2, mounting seat 1 top is provided with clamping and fixing mechanism 3, and mounting seat 1 top is provided with shielding mechanism 4;

[0030] Clamping and fixing mechanism 3 includes clamping assembly 31 and fixed assembly 32, and fixed assembly 32 is arranged at the right side of clamping assembly 31.

[0031] The clamping assembly 31 includes a threaded seat 311, which is fixedly connected to the top of the mounting base 1. A threaded plate 314 is rotatably connected to the top of the threaded seat 311. A slide frame 312 is fixedly connected to the front of the threaded seat 311. A stop block 315 is slidably connected inside the slide frame 312. A screw 313 is threadedly connected between the threaded plate 314 and the threaded seat 311 to facilitate the clamping of the workpiece.

[0032] Furthermore, the bottom of the stop block 315 contacts the top of the threaded plate 314, and a through groove is provided at the corresponding position of the slide frame 312 and the stop block 315, and the stop block 315 is slidably connected in the groove, which facilitates fixing the threaded plate 314 and the threaded seat 311.

[0033] Furthermore, the fixing component 32 includes a movable frame 321, which is rotatably connected to the right side of the screw 313. Adjusting blocks 327 are slidably connected inside both the movable frame 321 and the fixing frame 2. A pressure column 328 is fixedly connected to the outside of the adjusting block 327. A cam 325 is rotatably connected inside both the movable frame 321 and the fixing frame 2. A pull rod 326 is fixedly connected to the top of the cam 325. Friction blocks 324 are slidably connected to the front and rear inner walls of both the movable frame 321 and the fixing frame 2. A second spring 323 is fixedly connected between the friction block 324 and both the movable frame 321 and the fixing frame 2. A first spring 322 is fixedly connected between the movable frame 321, the fixing frame 2 and the adjusting block 327. This allows for adjustment of the appropriate position according to the appearance of the workpiece before fixing it.

[0034] Furthermore, the bottom of the cam 325 abuts against the top of the friction block 324, and the mounting base 1 and the moving frame 321 are provided with grooves at corresponding positions, and the moving frame 321 is slidably connected in the grooves, which facilitates the movement of the friction block 324.

[0035] Furthermore, grooves are provided at corresponding positions of the movable frame 321, the fixed frame 2, and the adjusting block 327, and the adjusting block 327 is slidably connected in the groove, so as to facilitate the movement of the adjusting block 327 when clamped.

[0036] Example 2:

[0037] Due to the existing technology, the waste generated during processing adheres to the outside of the screw 313, affecting the clamping effect. Please refer to [link / reference needed]. Figure 5 Furthermore, in conjunction with Embodiment 1, it is further found that the shielding mechanism 4 includes a connecting sleeve 41, which is fixedly connected to the back of the mounting base 1. A movable block 42 is slidably connected inside the connecting sleeve 41. A corrugated baffle 43 is fixedly connected to the top of the movable block 42. A connecting frame 44 is fixedly connected to the left side of the corrugated baffle 43 to prevent waste from falling onto the screw 313.

[0038] Further, the corrugated baffle 43 is fixedly connected to the left side of the moving frame 321, and the connecting frame 44 is fixedly connected to the left side of the connecting sleeve 41, so as to facilitate the extension and retraction of the corrugated baffle 43 and make it move with the moving frame 321.

[0039] In actual operation, when the device is used, first, when fixing the workpiece, according to the size of the workpiece, the screw 313 is manually rotated to drive the moving frame 321 to move, and then the left pressing column 328 gradually approaches the right pressing column 328, so that the workpiece placed between the two pressing columns 328 is in abutment. When facing the special-shaped surface, the corresponding adjusting block 327 is driven to move under the elastic force of the spring 323, and the pressing column 328 gradually synchronously approaches the special-shaped surface of the workpiece when the adjusting block 327 moves. Then, the two side pull rods 326 are manually pulled, so that the cam 325 is rotated with the fixed frame 2 or the connecting point of the moving frame 321 as the axis until it stops rotating by ninety degrees. At this time, the convex surface of the cam 325 drives the friction block 324 to move, so that the friction block 324 abuts against the top of the adjusting block 327, thereby fixing the adjusting block 327 after the movement. Then, the shielding mechanism 4 is arranged to pull the corrugated baffle 43 to move during the movement of the moving frame 321, thereby preventing the debris from splashing on the screw 313 during the machining process, thereby facilitating the subsequent clamping and moving.

[0040] It should be noted that, in the present document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the presence of additional identical elements in the process, method, article, or apparatus that comprises the element.
