Description

Technical Field

[0001] The utility model belongs to the technical field of tooling fixtures, and in particular relates to an adjustable fixture for a horizontal machining center. Background Art

[0002] The machining center is developed from the CNC milling machine. The biggest difference between the machining center and the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing tools of different uses on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changer in one clamping, realizing multiple machining functions. The horizontal machining center is one of the machining centers.

[0003] At present, horizontal machining centers use vises as fixtures to quickly position the workpiece to be processed. However, when positioning workpieces with more curved surfaces, the flat pressure fixation of the vise can damage the workpiece, resulting in workpiece defects. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problems and to provide an adjustable clamp for a horizontal machining center.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: an adjustable clamp for a horizontal machining center, comprising:

[0006] A fixed block, one end of which is provided with a piston groove, and the other end of the fixed block is provided with a plurality of piston holes, wherein the plurality of piston holes are connected to the piston groove;

[0007] A plurality of positioning rods, which are slidably connected in the plurality of piston grooves, and the plurality of positioning rods correspond to the plurality of piston grooves one by one;

[0008] A piston plate is slidably connected in the piston groove, and the piston groove between the piston plate and the plurality of positioning rods and the plurality of piston holes are filled with hydraulic oil;

[0009] A sealing plate, which is fixedly mounted on the end of the fixed block, and the sealing plate blocks the piston groove;

[0010] A driving rod passes through and is screwed on the sealing plate, one end of the driving rod is hinged to the piston plate, and the other end of the driving rod is provided with a hand-cranked wheel.

[0011] As a further description of the above technical solution:

[0012] The plurality of piston holes are arranged in a rectangular array.

[0013] As a further description of the above technical solution:

[0014] A sealing plug is provided at the end of the positioning rod, and the sealing plug abuts against the inner wall of the piston hole.

[0015] As a further description of the above technical solution:

[0016] A sealing strip is arranged on the edge of the piston plate, and the sealing strip abuts against the inner wall of the piston groove.

[0017] As a further description of the above technical solution:

[0018] A magnetic block is arranged at the bottom of the fixing block.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0020] The hydraulic oil in the piston groove is squeezed into the piston hole, and the hydraulic oil in the piston groove is squeezed into the piston hole. When the positioning rod corresponding to a certain piston hole contacts the surface of the workpiece, the hydraulic oil in the piston hole is in a saturated state, and the hydraulic oil preferentially enters the piston hole corresponding to the positioning rod that does not contact the surface of the workpiece, so that multiple positioning rods abut against different arc surfaces of the workpiece, thereby realizing rapid and adaptive positioning of the workpiece with more arc surfaces, avoiding damage to the workpiece during positioning, and improving the processing yield of the workpiece.
