Description

Technical Field

[0001] The present application relates to the technical field of aluminum profile CNC machining, and in particular to a special fixture used in an aluminum profile CNC machining center. Background Art

[0002] As we all know, CNC machining centers are developed from CNC milling machines. The biggest difference between them and CNC milling machines is that machining centers have the ability to automatically exchange machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changing device in one clamping to achieve multiple machining functions. CNC machining centers are high-efficiency automated machine tools composed of mechanical equipment and CNC systems that are suitable for machining complex parts. Before processing aluminum profiles, CNC machining centers often need to use fixtures to fix and limit the aluminum profiles to be processed.

[0003] At present, in the relevant technology, after searching, the utility model with patent publication number CN216681148U discloses a special clamp for aluminum profile CNC machining center, including a base and a mounting plate, an electric telescopic rod is arranged at the middle position of the upper end of the base, a rotating mechanism is arranged at the telescopic end of the electric telescopic rod, a mounting plate is arranged at the upper end of the rotating mechanism, an auxiliary mechanism is also arranged between the base and the mounting plate, a fixing mechanism is arranged at the upper end of the mounting plate, a buffer mechanism is arranged on the inner side of the fixing mechanism, the fixing mechanism includes fixing seats at both sides of the upper end of the mounting plate, a fixed push rod is arranged on the inner side of the fixed seat, and a fixing plate is arranged at the telescopic end of the fixed push rod.

[0004] Regarding the above-mentioned related technologies, when in use, although the electric telescopic rod is provided in conjunction with the rotating mechanism to achieve lifting and rotation, and the buffer mechanism is provided to effectively prevent damage to the surface of the aluminum profile during clamping, the applicant found that during use, it can only clamp and position aluminum profiles with regular shapes, and it is difficult to effectively limit the position of aluminum profiles with irregular shapes, which has certain limitations in use. Secondly, the overall structure is relatively complex, the convenience of use is low, and the practicality is insufficient.

[0005] Therefore, we propose a special fixture for CNC machining centers of aluminum profiles. Utility Model Content

[0006] The purpose of the utility model is to provide a special clamp for a CNC machining center for aluminum profiles to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A special fixture for aluminum profile CNC machining center, comprising:

[0009] Base;

[0010] Four arc-shaped slide blocks, each of which is slidably connected to the base through a slide groove, and a mounting plate is fixedly connected to the arc-shaped slide block;

[0011] Four sets of tightening mechanisms, which are arranged on the mounting plate and are used to fix and limit the profile material placed on the base;

[0012] The clamping mechanism comprises a vertical plate, which is fixedly welded on the mounting plate, one end of which is fixedly connected to two sliding columns, a sliding rod is slidably connected inside the sliding column, the other ends of the two sliding rods are fixedly connected to an arc-shaped clamping block, and a composite spring is fixedly connected between the arc-shaped clamping block and the vertical plate;

[0013] The positioning mechanism is arranged in the base and is used to stably place the base in a use position.

[0014] As a further solution of the utility model: a rubber cushion is arranged at one end of the arc-shaped pressing block, and a strip handle is arranged at one end of the vertical plate away from the arc-shaped pressing block.

[0015] As a further solution of the utility model: the positioning mechanism includes a plurality of pillars, and the plurality of pillars are all arranged in the base through mounting grooves, and the other ends of the pillars are fixedly connected to the vacuum suction cups.

[0016] As a further solution of the utility model: anti-slip pads are provided on the outer walls of both sides of the arc-shaped sliding block and fit tightly with the arc-shaped sliding groove.

[0017] As a further solution of the utility model: an anti-skid base is detachably connected to the base.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] By setting a positioning mechanism, the base is stably placed in the use position with the cooperation of multiple pillars and vacuum suction cups, and then the mounting plate is moved to a suitable position through the mutual cooperation of the base, arc-shaped slider and slide groove. Then, by setting a clamping component, after the aluminum profile to be limited is placed on the anti-slip base, the aluminum profile can be fixed and limited on the anti-slip base through the cooperation of the vertical plate, sliding column, sliding rod, arc-shaped clamping block and composite spring, so that the CNC machining center can perform processing on it.

[0032] The special fixture for the aluminum profile CNC machining center can be used to stably place the required base 1 in the use position by setting a positioning mechanism under the action of the positioning member mechanism, and then move multiple mounting plates 4 to the applicable position through the mutual coordination of the base 1, the arc-shaped slider 2 and the slide groove 3. Then, by setting a tightening component, the aluminum profile to be limited is placed on the anti-slip base 16, and the purpose of fixing and limiting the aluminum profile can be achieved under the action of the tightening component, so that the CNC machining center can perform processing on it.

[0033] exist Figure 1-3 Middle: The clamping mechanism includes a vertical plate 5, which is fixedly welded on the mounting plate 4, and one end of the vertical plate 5 is fixedly connected to two sliding columns 6, and a sliding rod 7 is slidably connected inside the sliding column 6, and the other ends of the two sliding rods 7 are fixedly connected to an arc-shaped clamping block 8, and a composite spring 9 is fixedly connected between the arc-shaped clamping block 8 and the vertical plate 5, one end of the arc-shaped clamping block 8 is provided with a rubber cushion 10, and the end of the vertical plate 5 away from the arc-shaped clamping block 8 is provided with a strip handle 11.

[0034] This special clamp for aluminum profile CNC machining center, through the setting of this structure, after the aluminum profile to be processed is placed on the anti-slip base 16, the spring force of the composite spring 9 can be used to make the sliding rod 7 slide in the sliding column 6, thereby pushing its arc-shaped clamping block 8 to move, so that the arc-shaped clamping block 8 cooperates with the rubber cushion 10 to fix the aluminum profile on the anti-slip base 16, thereby facilitating the CNC machining center to process the aluminum profile.
