If the specific posture changes, the directional indication will also change accordingly.

[0026] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] The gantry is a new type of small lifting gantry developed to meet the daily production needs of medium and small factories (companies) for handling equipment, warehouse loading and unloading, lifting and repairing heavy equipment, and material transportation.

[0028] In the related art, when processing a workpiece, a clamping device is required to clamp the workpiece to avoid deviation of the workpiece during processing. However, the existing clamping and fixing mechanism is generally fixed directly to the workbench of the gantry, which is inconvenient to store and is easily damaged by collision.

[0029] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a milling machine gantry frame. When the workpiece needs to be processed, it is only necessary to start the motor 14 to drive the bidirectional screw rod 15 to rotate, so that the movable plates 16 on both sides can be expanded to both sides, and then the limit blocks 17 are erected, and the limit blocks 17 are limited by the baffles 18, and then the movable plates 16 on both sides are closed, so that the workpiece can be squeezed and limited by the limit blocks 17, and the workpiece can be processed by the gantry body 12. After use, the limit blocks 17 and the movable plates 16 can be put into the interior of the frame 13, so that the clamping assembly 1 can be avoided from being exposed to the outside, which protects the clamping assembly 1 and increases the service life of the device.

[0030] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0031] Combine Figure 1-Figure 2 The embodiment of the present application provides a milling machine gantry frame, including a clamping assembly 1; the clamping assembly 1 includes: a workbench 11 with a gantry body 12 on the top; a frame 13 is arranged on the top of the workbench 11; a fixed plate 131 is symmetrically arranged on the inner side of the frame 13; a motor 14 is arranged on the inner side of the frame 13; a bevel gear 141 is arranged on the output shaft of the motor 14; a bidirectional screw rod 15 is arranged on the inner side of the frame 13 and passes through the fixed plate 131; a bevel gear 2 151 is arranged on the outer side of the bidirectional screw rod 15 and meshes with the bevel gear 141; a movable plate 16 is symmetrically arranged on the inner side of the frame 13 and threadedly connected to the bidirectional screw rod 15; a groove 161 is symmetrically opened on the top of the movable plate 16; a limit block 17 is hinged to the inner side of the groove 161; and a baffle 18 is arranged on the movable plate 16.

[0032] When in use, first start the motor 14 through an external power supply to drive the bevel gear 141, and the bevel gear 141 drives the bevel gear 2 151 engaged with it to rotate, thereby driving the bidirectional screw rod 15 to rotate. Since the movable plates 16 on both sides are respectively connected to the two ends of the bidirectional screw rod 15 through threads, and the threads on both sides of the bidirectional screw rod 15 are opposite, the movable plates 16 on both sides can be driven to expand to both sides. Since the limit block 17 is hinged to the groove 161, the limit block 17 can be rotated 90 degrees to make it stand upright, and the limit block 17 is limited by the baffle 18 (reference Figure 1 ), after completion, the workpiece to be processed is placed on the top of the frame 13, and then the motor 14 is rotated in the opposite direction, so that the movable plates 16 on both sides can be closed, so that the workpiece can be squeezed and limited by the upright limit blocks 17, and the workpiece can be processed by the gantry body 12. After use, the limit blocks 17 and the movable plates 16 can be put into the interior of the frame 13, so that the clamping component 1 can be avoided from being exposed to the outside, which plays a protective role for the clamping component 1 and increases the service life of the device. The workpiece is not reflected in the drawings of the specification. The operating principle of the gantry body 12 refers to the "

[0023] " paragraph of the patent "CN221088055U" specification, which is common knowledge and will not be repeated here.

[0033] In some embodiments, an auxiliary component 2 is provided on the frame 13 , and the auxiliary component 2 includes: a slide groove 21 symmetrically opened on the frame 13 ; a slide rod 22 symmetrically provided on the movable plate 16 and passing through the movable plate 16 .

[0034] Slide grooves 21 are symmetrically provided on both sides of the frame 13, and slide rods 22 are symmetrically provided on both sides of the movable plate 16. In this way, the slide rods 22 can move inside the slide grooves 21 when the movable plate 16 moves, which can limit the movable plate 16 and avoid the movable plate 16 from detaching from the inside of the frame 13 due to the lack of a limiting mechanism of the movable plate 16, which requires re-debugging, making it more convenient to use.

[0035] In some embodiments, the auxiliary component 2 further includes a magnet 23 disposed on the baffle 18 .

[0036] A magnet 23 is provided on one side of the baffle 18, and the limit block 17 is made of metal, so that the limit block 17 can be adsorbed and limited by the magnet 23, thereby preventing the limit block 17 from moving when the movable plate 16 moves, thereby increasing the structural stability of the device.

[0037] In some embodiments, the sliding rod 22 is a screw rod.

[0038] The slide rod 22 is set as a screw and is threadedly connected to the movable plate 16. In this way, the slide rod 22 can be removed from both sides of the movable plate 16 by screwing. In this way, the movable plate 16 can be taken out from the inside of the frame 13 without a limiting mechanism to replace the parts on the movable plate 16.

[0039] In some embodiments, the auxiliary component 2 further includes pulleys 24 symmetrically arranged on the top of the movable plate 16 .

[0040] Pulleys 24 are symmetrically arranged on the top of the movable plate 16, so that when the movable plate 16 moves back and forth, the pulleys 24 can slide on the inner top of the frame 13, reducing the friction between the movable plate 16 and the frame 13, making the movable plate 16 move more stably.

[0041] In some embodiments, the auxiliary component 2 further includes a rubber pad 25 disposed on the limiting block 17 .

[0042] A rubber pad 25 is provided on one side of the limit block 17 , which can make the limit block 17 more stable in fixing the workpiece by increasing friction, avoid deviation of the workpiece during processing, and increase the structural stability of the device.

[0043] In some embodiments, the baffle 18 is connected to the movable plate 16 by bolts.

[0044] The baffle 18 and the movable plate 16 are connected by bolts, so that when the baffle 18 is damaged or deformed, it is convenient to remove the baffle 18 and replace it, so as not to affect the subsequent limiting of the limit block 17.

[0045] In some embodiments, the auxiliary component 2 further includes a pull groove 26 opened on the limit block 17 .

[0046] A pull groove 26 is provided on one side of the limit block 17 , so that when the limit block 17 needs to be pulled up later, the operator inserts his fingers into the inner side of the pull groove 26 , and thus the limit block 17 can be pulled up, making the operation more convenient and increasing the working efficiency.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.
