Description

Technical Field

[0001] The utility model relates to the technical field of milling machine clamps, in particular to a vertical milling machine clamp. Background Art

[0002] A milling machine is a machine tool that uses a milling cutter to cut workpieces. Usually, the milling cutter mainly moves in rotation. Currently, when a milling machine processes a workpiece, a fixture is required to fix the workpiece to be processed. First, the relative position of the workpiece and the fixture must be determined on the machine tool, and then the workpiece must be clamped with the fixture. The process from positioning the workpiece to clamping the workpiece is called clamping.

[0003] At present, when the vertical milling machine fixture is used to clamp some long plate workpieces, workers usually use the fixture to clamp the workpiece in the center or clamp one end of the long plate workpiece, which makes the clamping processing stability of the long plate workpiece in the vertical milling machine poor, thereby affecting the processing stability of the long plate workpiece, and when the opposing fixture is installed and replaced on the worktable surface of the vertical milling machine, it is necessary to disassemble multiple sets of fixed pressure plates used for clamping the fixture on the worktable surface of the vertical milling machine, which makes it more cumbersome to adjust the clamping position of the workpiece. For this reason, we propose a vertical milling machine fixture. Utility Model Content

[0004] The main purpose of the utility model is to provide a vertical milling machine clamp. By setting a clamp for clamping a long plate workpiece for a vertical milling machine, the clamp base plate of the clamp can be installed normally according to the installation method of the existing vertical milling machine clamp, and a plurality of clamping structures whose positions can be manually adjusted are arranged on the clamp base plate. The clamping structures are driven by a hydraulic cylinder and can clamp the long plate workpiece in opposite directions, thereby realizing multi-point clamping of the long plate workpiece at the clamp base plate, and when moving, the clamping structure only needs to slightly screw down the upper bolt, so that the position of the clamping structure can be adjusted as needed at the slide groove of the clamp, thereby facilitating the convenient change of the clamping position at the vertical milling machine, meeting the demand for easy installation and replacement of the clamp, and effectively solving the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0011] Furthermore, the bolt body length of the bolt is the same as the seat tube depth of the T-shaped tube seat;

[0012] By adopting the above technical solution, after the bolt is screwed out of the seat pipe mouth of the T-shaped pipe seat, the T-shaped head above the rotary block can be pressed against the bottom of the L-shaped back support plate, so that the T-shaped pipe seat, bolt, rotary block and T-shaped head form a supporting and positioning structure between the L-shaped back support plate and the fixture base plate, preventing the hydraulic push cylinder from moving when pushing the push block to clamp the workpiece.

[0013] Furthermore, the L-shaped support is pressed on the surface of the upper seat plate of the L-shaped back support plate to form a C-shaped groove, and a cylinder body of a hydraulic push cylinder is inserted into the C-shaped groove;

[0014] By adopting the above technical solution, the L-shaped support can clamp the cylinder body of the hydraulic push cylinder with the C-shaped groove.

[0015] Furthermore, the height of the L-shaped back-facing support plate is smaller than the height of the push block, and the bottom block surface of the push block is pressed against the surface of the fixture base plate;

[0016] By adopting the above technical solution, the block of the push block can be squeezed out of the L-shaped plate body facing away from the support plate to clamp the workpiece on the surface of the clamp base plate.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0024] The connecting plate 12 is welded to the outside of the telescopic rod head of the hydraulic push cylinder 11, and the plate body of the connecting plate 12 and the block body of the push block 13 are screwed with a fastening bolt;

[0025] By adopting the above technical solution, the telescopic rod head of the hydraulic push cylinder 11 can be locked and installed with the help of the connecting plate 12 and the fastening bolt and the push block 13.

[0026] The seat plate of the T-shaped tube seat 5 is pressed on the surface of the fixture base plate 1 between the L-shaped back support plate 2 and the slide groove 3, and a seat tube with a threaded hole is welded on the surface of the seat plate of the T-shaped tube seat 5;

[0027] By adopting the above technical solution, after the T-shaped tube seat 5 obtains support on the surface of the fixture base plate 1, the bolt 6 can be screwed on the seat tube with the threaded hole.

[0028] The bolt body length of the bolt 6 is the same as the seat tube depth of the T-shaped tube seat 5;

[0029] By adopting the above technical solution, after the bolt 6 is screwed out of the seat tube mouth of the T-shaped tube seat 5, the T-shaped head 8 above the rotary block 7 can be pressed against the bottom of the L-shaped back support plate 2, so that the T-shaped tube seat 5, the bolt 6, the rotary block 7 and the T-shaped head 8 form a supporting and positioning structure between the L-shaped back support plate 2 and the fixture base plate 1, preventing the hydraulic push cylinder 11 from moving when pushing the push block 13 to clamp the workpiece.

[0030] The L-shaped support 9 is pressed on the upper seat plate surface of the L-shaped back support plate 2 to form a C-shaped groove 10, and a cylinder body of a hydraulic push cylinder 11 is inserted into the C-shaped groove 10;

[0034] It should be noted that the utility model is a vertical milling machine clamp. When using the utility model clamp, the clamp base plate 1 can be normally placed on the worktable surface of the vertical milling machine, and then the fixed pressure plate used for normal clamp installation is used to cooperate with the bolts to clamp the clamp base plate 1 at multiple points at the installation groove of the worktable, so that the clamp is fixed to the worktable surface, and then the slide plate 4 can slide in the slide groove 3, so that the L-shaped support 9 with the hydraulic push cylinder 11 installed with the push block 13 moves to the position where the long plate of the workpiece needs to be clamped, and the bolt 6 is screwed out of the seat tube of the T-shaped tube seat 5 by using a wrench to clamp the rotary block 7, so that the T-shaped head 8 above the rotary block 7 is pressed against the lower surface of the L-shaped back support plate 2, and the T-shaped tube seat 5, the bolt 6, the rotary block 7 and the T-shaped head 8 form a supporting positioning structure between the L-shaped back support plate 2 and the clamp base plate 1 to prevent the hydraulic push cylinder 11 from moving when pushing the push block 13 to clamp the workpiece. At this time, the hydraulic push cylinder 11 can be connected to an external hydraulic control end for hydraulically driven extension, thereby pushing the push block 13 outside the connecting plate 12. The workpiece can be placed in advance on the surface of the fixture base plate 1 between the L-shaped back support plate 2, and then the push block 13 cooperates with the resistance block 14 to press against the long plate workpiece under the support of the hydraulic push cylinder 11. A plurality of groups of clamping structures equipped with hydraulic cylinder bodies 11 can be set on the surface of the fixture base plate 1 for distributed installation as needed, so as to perform multi-point opposite clamping on the long plate workpiece, which is convenient for the long plate workpiece to be stably processed on the vertical milling machine. When moving this clamping structure, it is only necessary to screw the bolt 6 under the T-shaped head 8 into the seat tube of the T-shaped tube seat 5, so that the T-shaped head 8 leaves the L-shaped back support plate 2, and then the sliding clamping structure can be changed as needed. After the long plate workpiece is clamped, the hydraulic push cylinder 11 can pull the push block 13 and the resistance block 14 away from the workpiece, making it convenient for workers to pick up the workpiece.
