Technical Field

[0001] The utility model relates to the technical field of metal cutting, in particular to a positioning mechanism for manufacturing metal cutting machine tools. Background Art

[0002] Metal cutting machine tools are a large category of machine tools. They are mainly used to process various metal workpieces through cutting, grinding or special processing methods to obtain the required geometric shape, dimensional accuracy and surface quality. Metal cutting machine tools are widely used in machine tools, automobiles, aerospace, ships, power equipment, agricultural machinery, engineering machinery, railway locomotives and other fields. In order to ensure the position accuracy and stability of parts during the processing, thereby improving processing accuracy and efficiency, a positioning mechanism is needed.

[0003] At present, different positioning mechanisms are required for the positioning mechanisms of processed parts due to the different shapes and sizes of the parts. This requires disassembly and replacement of different positioning mechanisms during the cutting process of different parts, which reduces the working efficiency of metal cutting machine tools and the practicality of existing positioning mechanisms.

[0007] The first positioning assembly includes a fixing plate, a threaded rod, a connecting shaft, a connecting rod, and a clamping plate. A threaded hole is provided on the top of the fixing plate, the threaded rod is matched with the threaded hole, one end of the threaded rod is fixedly connected with the connecting shaft, a through hole is provided on the connecting shaft, the connecting rod is matched with the through hole, a bearing seat is fixedly connected with the outer surface of the clamping plate, a bearing is provided in the bearing seat, the end of the threaded rod is matched with the inner ring of the bearing, a groove is provided on the clamping plate, a spring is fixedly connected in the groove, and a clamping block is fixedly connected with the end of the spring;

[0008] The second positioning assembly has the same structure as the first positioning assembly.

[0009] Preferably, the first positioning assembly also includes a positioning rod, a fixing block, a hexagon socket bolt and a nut. The positioning rod is fixedly connected to the surface of the clamping plate. The fixing plate is provided with a positioning hole. The positioning rod cooperates with the positioning hole. The fixing block is fixed to the outer surface of the fixing plate. The fixing block is provided with a connecting hole.

[0013] Preferably, the first positioning assembly and the second positioning assembly are symmetrically arranged on the machine tool.

[0014] The utility model has the following beneficial effects:

[0015] When positioning the workpiece for metal cutting, the threaded rod engages with the thread of the threaded hole, pushing the clamp to perform axial displacement, pushing the clamp block to contact the workpiece, causing the spring to contract and generate a reaction force to fix and clamp the workpiece. Due to the different degrees of expansion and contraction of each spring, the clamp block can fit workpieces of different shapes, effectively expanding the applicability of the positioning mechanism to suit different workpieces. There is no need to repeatedly disassemble and replace the positioning mechanism, thereby enhancing practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A positioning mechanism for metal cutting machine tool manufacturing includes a machine tool 1 and a first positioning component 2. A fixing plate 201 is provided on the machine tool 1. A second positioning component 3 is provided on the machine tool 1. A mounting hole is opened on the machine tool 1.

[0024] The first positioning assembly 2 includes a fixed plate 201, a threaded rod 202, a connecting shaft 203, a connecting rod 204, and a clamping plate 207. A threaded hole is provided on the top of the fixed plate 201, and the threaded rod 202 is matched with the threaded hole. One end of the threaded rod 202 is fixedly connected to the connecting shaft 203. A through opening is provided on the connecting shaft 203, and the connecting rod 204 is matched with the through opening. A bearing seat 206 is fixedly connected to the outer surface of the clamping plate 207, and a bearing 205 is arranged in the bearing seat 206. The end of the threaded rod 202 is matched with the inner ring of the bearing 205. A groove is provided on the clamping plate 207, and a spring 209 is fixedly connected in the groove. A clamping block 2010 is fixedly connected to the end of the spring 209. There are multiple clamping blocks 2010, and the clamping blocks 2010 are matched with the groove.

[0025] When positioning the workpiece for metal cutting, the connecting rod 204 is manually pulled, and the connecting rod 204 drives the connecting shaft 203 and the threaded rod 202 to rotate, so that the threaded rod 202 engages with the thread of the threaded hole, and the end of the threaded rod 202 rotates in the bearing 205, thereby pushing the bearing seat 206 and the clamping plate 207 to perform axial displacement, and the positioning rod 208 moves in the positioning hole, thereby pushing the clamping block 2010 to contact the workpiece, so that the spring 209 contracts to generate a reaction force to fix and clamp the workpiece. When positioning and clamping workpieces of different shapes and sizes, the clamping block 2010 fits workpieces of different shapes due to the different degrees of expansion and contraction of each spring 209, thereby effectively expanding the application surface of the positioning mechanism to adapt to different workpieces, and there is no need to repeatedly disassemble and replace the positioning mechanism, thereby enhancing practicality.

[0026] The first positioning assembly 2 also includes a positioning rod 208, a fixing block 2011, a hexagon socket bolt 2012 and a nut 2013. The positioning rod 208 is fixedly connected to the surface of the clamping plate 207. A positioning hole is provided on the fixing plate 201.

The fixing block 2011 is fixed on the outer surface of the fixing plate 201. A connecting hole is provided on the fixing block 2011. The hexagon socket bolt 2012 cooperates with the connecting hole and the nut 2013 on the fixing block 2011. The hexagon socket bolt 2012 passes through the mounting hole.

[0027] The first positioning assembly 2 is fixed to the machine tool 1 by the cooperation of the fixing block 2011, the hexagon socket bolt 2012 and the nut 2013, and it is also very convenient to disassemble and assemble. The first positioning assembly 2 or the second positioning assembly 3 can be directly removed by only unscrewing and removing the nut 2013 with a tool.

[0028] The second positioning assembly 3 has the same structure as the first positioning assembly 2 , and the first positioning assembly 2 and the second positioning assembly 3 are symmetrically arranged on the machine tool 1 .
