DETAILED DESCRIPTION
[0018] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
[0019] Example: See Figure 1-3 In order to solve the problem that the clamping efficiency of the current bench vise is low and it is difficult to ensure the high-efficiency processing requirements, and at the same time solve the technical problem that the current bench vise cannot ensure the clamping effect of the workpiece, a quick-change clamp for mechanical processing is set up, including an operating platform 1, a sliding fixed structure is provided at the upper end of the operating platform 1, and a driving adjustment structure is provided at the lower end of the operating platform 1, and both ends of the driving adjustment structure are connected to both ends of the sliding fixed structure;
[0020] The sliding fixing structure comprises: two sliding installation grooves 2, two operating grooves 3, two sliding blocks 4, two installation frames 5, two installation plates 6, four fixing sleeves 7 and two clamping plates 8;
[0021] Two sliding mounting grooves 2 are respectively opened on both sides of the upper end of the operating platform 1, two operating grooves 3 are respectively opened at the lower ends of the two sliding mounting grooves 2, two sliding blocks 4 are respectively movably embedded in the two sliding mounting grooves 2, two mounting frames 5 are respectively installed on the upper ends of the two sliding blocks 4, two mounting plates 6 are respectively embedded in the two mounting frames 5, four fixed sleeves 7 are respectively installed on both sides of the two mounting plates 6, and one ends of the two clamping plates 8 are respectively movably embedded in the four fixed sleeves 7.
[0022] When in use, the staff first moves the device to the lower end of the designated processing equipment and supports the device through the operating platform 1. The bottom of the operating platform 1 can also be padded according to different usage requirements to change the overall height of the operating platform 1, and then the air source is connected to the driving adjustment structure. During the processing, the staff can embed the designated clamping plate 8 into the fixed sleeve 7 according to the fixation requirements of the workpiece, and fix it with bolts to meet the workpiece clamping effects of different requirements. The staff places the workpiece on the upper end of the operating platform 1, and then drives the driving cylinder 9 in the adjusting structure to work, so that the two sliding blocks 4 move synchronously toward the center in the two sliding mounting grooves 2, and the two clamping plates 8 are moved inward to clamp the two sides of the workpiece. It only needs to repeatedly drive the driving cylinder 9 at the lower end of the operating platform 1 to achieve multiple clamping and fixing operations, and the mounting frame 5 cooperates with the mounting plate 6 to achieve the overall disassembly of the clamping plate 8 and the mounting plate 6, which is convenient for the subsequent storage and replacement of the clamping plate 8 and the mounting plate 6.
[0023] Further, the driving and adjusting structure comprises: a driving cylinder 9, a pressure sensor 10, an adjusting threaded rod 11, two nuts 12, a connecting sleeve 13, two connecting rods 14 and two connecting blocks 15;
[0024] The driving cylinder 9 is fixedly installed at the center of the lower wall of the operating platform 1, the pressure sensor 10 is fixedly installed on the telescopic end of the driving cylinder 9, the adjusting threaded rod 11 is located at the lower end of the pressure sensor 10, the two nuts 12 are movably mounted on the upper end of the adjusting threaded rod 11, the connecting sleeve 13 is movably mounted on the upper end of the adjusting threaded rod 11, one end of the two connecting rods 14 is respectively hinged to the two sides of the connecting sleeve 13, the two connecting blocks 15 are respectively installed at the lower ends of the two sliding blocks 4, and are movably embedded in the two operating grooves 3, and the top ends of the two connecting rods 14 are respectively hinged to the two connecting blocks 15.
[0025] When clamping the workpiece, the cylinder 9 is driven to push the pressure sensor 10 and the adjusting threaded rod 11 downward, so that the connecting sleeve 13 between the two nuts 12 moves downward accordingly, so that the angles of the two connecting rods 14 between the connecting sleeve 13 and the two connecting blocks 15 change, thereby making the connecting block 15 and the sliding block 4 move in the operating groove 3 and the sliding installation groove 2. The value of the pressure sensor 10 can be observed during clamping to avoid damage to the surface of the workpiece due to excessive values, and to avoid that the value is too small and cannot meet the clamping requirements, thereby ensuring the overall clamping stability of the workpiece. The adjusting threaded rod 11 is arranged to cooperate with the two nuts 12 to change the overall height of the connecting sleeve 13 at the upper end of the adjusting threaded rod 11, so that the travel range of the connecting sleeve 13 can be adjusted to meet the driving operation of different clamping plates 8.
[0026] Furthermore, a dovetail-shaped clamping block 16 is processed on one side of the clamping plate 8 .
[0027] Furthermore, the mounting plate 6 is fixed in the mounting frame 5 by bolts.
[0028] Furthermore, a cylinder frame 17 is provided at the connection between the driving cylinder 9 and the operating platform 1 .
[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
