Description

Technical Field

[0001] The utility model belongs to the technical field of numerically controlled lathe processing, and in particular relates to a multi-station fixing device for numerically controlled lathe processing. Background Art

[0002] CNC lathe processing is a high-precision and high-efficiency mechanical processing method in which digital information is used to control the displacement of parts and tools by automated machine tools. In the process of CNC lathe processing multiple plate workpieces at the same time, it is necessary to use a multi-station fixture to fix multiple plate workpieces at the same time, which is conducive to the simultaneous processing of multiple plate workpieces.

[0003] The existing patent (publication number: CN219767465U) discloses a multi-station fixing device for a CNC lathe, comprising a CNC lathe body and a processing table, wherein two clamping plates for horizontally clamping workpieces are installed on the top outer wall of the processing table, and the top outer walls of the two clamping plates are fixedly connected with T-shaped slide rails, and the outer walls of the two T-shaped slide rails are slidably connected with two adjustment blocks, and the top outer walls of the multiple adjustment blocks are fixedly connected with L-shaped brackets, and the outer walls of the multiple L-shaped brackets are provided with fixing components for vertically limiting the workpieces. However, when the device is in use, it is impossible to simultaneously fix multiple plate workpieces, so that the plate workpieces can only be processed individually when being processed in the CNC lathe, which reduces the processing efficiency of the CNC lathe on the plate workpieces;

[0004] In addition, during the process of fixing the plate workpiece, the device fixes the workpiece in multiple directions, and multiple screws need to be turned to make the rubber pad press the workpiece. Fixing the workpiece in this way results in low workpiece fixing efficiency, and the workpiece still needs to be fixed manually, which makes loading and unloading the workpiece extremely cumbersome.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] See also Figure 1 - Figure 5As shown, a multi-station fixing device for CNC lathe processing includes a base 1: a plurality of supporting legs 2 are fixedly connected at equal distances at the top of the base 1, a mounting plate 3 is fixedly connected to the top of the supporting legs 2, a plurality of fixing mechanisms 4 are fixedly and insertedly connected at equal distances in the mounting plate 3, two movable wheels 9 are tightly attached to one side of the bottom end of the fixing mechanism 4, connecting rods 8 are movably and insertedly connected to the two sides of the movable wheel 9, the movable wheel 9 is supported by the connecting rods 8, and the bottom ends of two adjacent connecting rods 8 are fixedly connected to a pad 7, the bottom ends of the pad 7 are fixedly connected to a movable plate 6, the middle part of the bottom end of the movable plate 6 is fixedly connected to an electric telescopic rod 5, and the bottom end of the electric telescopic rod 5 is fixedly connected to the top of the base 1.

[0026] Depend on Figure 1 and Figure 2 - Figure 4 It can be seen that the fixing mechanism 4 includes a limiting mechanism 41, a pushing plate 42, a triangular plate 43 and an L-shaped clamping seat 44. There are two pushing plates 42, triangular plates 43 and L-shaped clamping seats 44 in total, and one end of the two pushing plates 42 can move through one end of the limiting mechanism 41 and extend into the limiting mechanism 41. The L-shaped clamping seats 44 are respectively fixedly connected to one end of the two pushing plates 42. Two through holes 45 are provided at one end of the L-shaped clamping seats 44 away from the pushing plates 42. The two triangular plates 43 are respectively fixedly connected to the other ends of the two pushing plates 42. The limiting mechanism 41 is fixedly inserted and connected in the mounting plate 3; the limiting mechanism 4 1 includes a connecting frame 411, an L-shaped fixing seat 413, a connecting column 414, a spring 415 and a supporting plate 416. There are two L-shaped fixing seats 413, and the two L-shaped fixing seats 413 are fixedly connected to both sides of the inner wall of the connecting frame 411. There are four connecting columns 414 and four springs 415, and two groups of connecting columns 414 are fixedly connected to one end of the two L-shaped fixing seats 413. The four springs 415 are respectively sleeved on the outer surfaces of the four connecting columns 414. Two through grooves 412 are provided at one end of the inner wall of the connecting frame 411, and the supporting plate 416 is fixedly inserted and connected in the connecting frame 411.

[0027] As can be seen from the above, the plate workpiece is placed on the upper end of the support plate 416, and the electric telescopic rod 5 is started. The output end of the electric telescopic rod 5 extends and drives the movable plate 6 fixedly connected thereto to move upward, and the movable plate 6 pushes the pad plate 7 fixedly connected thereto to move upward, and the pad plate 7 pushes the connecting rod 8 fixedly connected thereto to move upward, and pushes the movable wheel 9 movably connected thereto to move upward through the connecting rod 8. When the movable wheel 9 moves upward, it pushes the triangular plate 43 to move in the mounting plate 3, and at the same time, the triangular plate 43 pushes the pushing wheel 7 fixedly connected thereto to move upward. The plate 42 is displaced, pushing the plate 42 to slide in the through groove 412 and pushing the L-shaped clamping seat 44 fixedly connected to it to be displaced, and the L-shaped clamping seat 44 slides on the outer surface of the connecting column 414 and squeezes the spring 415, causing the spring 415 to contract, thereby clamping the plate workpiece between the L-shaped fixed seat 413 and the L-shaped clamping seat 44 in the connecting frame 411, and using multiple movable wheels 9 to push multiple triangular plates 43 to move, and multiple plate workpieces can be clamped at the same time, which is beneficial to the rapid processing of the plate workpieces and improves the loading efficiency of the plate workpieces.

[0028] For details about the above, refer to Figure 3 and Figure 4 As shown, the two through slots 412 are movably connected with the two push plates 42 respectively, the two ends of the spring 415 are fixedly connected with the L-shaped clamping seat 44 and the L-shaped fixing seat 413 respectively, and the connecting column 414 is movably connected with the through hole 45.

[0029] As can be seen from the above, by setting the support plate 416, the plate workpiece can be supported, which is convenient for CNC lathe to process it. By movably connecting the connecting column 414 and the insertion hole 45, the L-shaped clamping seat 44 can be limited, thereby improving the stability of the movement of the L-shaped clamping seat 44. Rubber pads are provided on the inner walls of the L-shaped clamping seat 44 and the L-shaped fixing seat 413 to avoid wear on the plate workpiece when fixing the plate workpiece. By setting the spring 415, the reset of the triangle plate 43 is facilitated.

[0032] As can be seen from the above, the fixing mechanism 4 is installed in the installation groove 32, and the limiting groove 33 and the through groove 34 are used to limit the triangular plate 43 and the push plate 42. When the triangular plate 43 and the push plate 42 move, they can be stably displaced by the limiting groove 33 and the through groove 34, further improving the stability of the displacement of the L-shaped clamping seat 44.

[0033] Preferably, several through grooves 34 are respectively connected to the inside of several limiting grooves 33, and the through grooves 34 and the pushing plates 42 are movably inserted and connected together; the triangular plate 43 is movably inserted and connected in the limiting grooves 33, and the bottom end of the triangular plate 43 is in close contact with the outer surface of the movable wheel 9.

[0034] As can be seen from the above, the through slot 34 can limit the push plate 42 , and the limiting slot 33 can limit the triangular plate 43 .
