Description
Technical Field
[0001] The utility model relates to the technical field of numerically controlled gantry boring and milling machines, in particular to a numerically controlled gantry boring and milling machine with a noise reduction device. Background Art
[0002] CNC gantry boring and milling machines are widely used in the industrial field and are suitable for finishing and roughing in all walks of life. The overall structure of CNC gantry boring and milling machines consists of a gantry frame, which is composed of double columns, movable crossbeams, connecting beams, transverse slides and milling head slides. The crossbeam moves up and down along the column guide rail (W axis), and a vertical high-power multifunctional slide-type boring and milling head is configured on the crossbeam. The slide-type boring and milling head moves left and right (Y axis) and up and down (Z axis) along the crossbeam guide rail, and the gantry frame moves longitudinally along the bed (X axis).
[0003] Existing CNC gantry boring and milling machines generate noise when processing workpieces, which can easily affect the health of operators.
[0004] For example, a CNC gantry boring and milling machine with a noise reduction device disclosed in Chinese patent CN218746521U protects the CNC gantry boring and milling machine body when processing a workpiece through a protection mechanism installed on the CNC gantry boring and milling machine body, and reduces noise; the protection mechanism is locked through a feed mechanism installed on the CNC gantry boring and milling machine body; and the contact between the CNC gantry boring and milling machine body and the ground is reduced through a shock-absorbing mechanism installed on the CNC gantry boring and milling machine body, thereby further reducing noise; and the high temperature generated during processing is cooled down through a spray mechanism installed on the CNC gantry boring and milling machine body. Therefore, the CNC gantry boring and milling machine with a noise reduction device is convenient for reducing the noise generated by the CNC gantry boring and milling machine when processing workpieces, thereby reducing the impact on the health of operators.
[0005] However, the device cannot adjust the height of the four legs of the CNC gantry boring and milling machine during use. When the ground is uneven, the CNC gantry boring and milling machine will bump during operation, causing the CNC gantry boring and milling machine to collide with the ground, thereby generating noise and affecting the health of the operator.
[0006] For this reason, we urgently need to provide a kind of CNC gantry boring and milling machine with noise reduction device. Utility Model Content
[0007] The purpose of the utility model is to provide a CNC gantry boring and milling machine with a noise reduction device to solve the problem proposed in the above background technology that the height of the four legs of the CNC gantry boring and milling machine cannot be adjusted during use. When the ground is uneven, the CNC gantry boring and milling machine will bump during operation, causing the CNC gantry boring and milling machine to collide with the ground, thereby generating noise and affecting the health of the operator.
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a CNC gantry boring and milling machine with a noise reduction device, comprising an outer shell, a door body and a support plate, the door body being slidably connected to the left and right sides of the front side of the outer shell, the support plate being arranged under the outer shell, and a noise reduction device being arranged under the outer shell.
[0009] The noise reduction device comprises an adjustment unit and a shock absorbing unit, wherein the adjustment unit is arranged at the bottom of the support plate, and the shock absorbing unit is arranged at the top of the support plate.
[0010] The adjusting unit includes an upper support column, a lower support column, a base, a bearing, a gear, a telescopic member and a rack. The upper support column is fixedly installed around the bottom of the support plate, the lower support column is installed at the lower end inside the upper support column, the base is installed at the bottom of the lower support column, the bearing is fixedly installed inside the base, the gear is fixedly installed on the outer side of the lower end of the lower support column, the telescopic member is fixedly installed on one side of the top of the base, and the rack is fixedly installed at the output end of the telescopic member.
[0011] Preferably, the shock absorbing unit comprises a shock absorbing spring and a damping rod, the shock absorbing spring is fixedly mounted on the top of the support plate, and the damping rod is mounted on the inner side of the shock absorbing spring.
[0012] Preferably, a CNC gantry boring and milling machine is installed inside the shell. When the CNC gantry boring and milling machine processes a workpiece, the shell is sealed by the door body, thereby blocking noise generated during processing.
[0013] Preferably, the adjustment units are symmetrically distributed around the bottom of the support plate, the upper support column is provided with an internal thread, the lower support column is provided with an external thread, and the lower support column is threadedly connected to the interior of the upper support column. By rotating the lower support column, when the lower support column is threadedly connected to the upper support column, the upper support column moves up and down to adjust the height of the four legs of the outer shell to prevent the outer shell from shaking due to uneven ground.
[0014] Preferably, the bottom of the lower support column is fixedly installed on the inner ring of the bearing, and the gear and rack are meshed with each other. The rack is pushed to move left and right by starting the telescopic member, and the rack meshes with the gear when it moves, so that the gear drives the lower support column to rotate around the inner ring of the bearing, thereby realizing the meshing of the lower support column and the upper support column, and then realizing the adjustment of the height of the four legs of the outer shell.
[0015] Preferably, the top of the shock-absorbing spring is fixedly connected to the bottom of the shell, and when the CNC gantry boring and milling machine vibrates when processing the workpiece, the vibration is damped by the shock-absorbing spring and the damping rod, thereby reducing the noise generated by the collision between the base and the ground.
[0016] Preferably, a rubber pad is installed at the bottom of the base, and the rubber pad further reduces the noise generated by the collision between the base and the ground.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] 1. The CNC gantry boring and milling machine with a noise reduction device is provided with an adjustment unit. When the outer shell shakes due to an uneven ground, the telescopic part is started to push the rack to move left and right, and the rack meshes with the gear when it moves, so that the gear drives the lower support column to rotate around the inner ring of the bearing. When the lower support column rotates, it is threadedly connected with the upper support column, so that the upper support column pushes one end of the support plate to move up and down, and the height of the four legs of the outer shell is adjusted until the outer shell does not shake, thereby avoiding a large shake of the outer shell of the CNC gantry boring and milling machine during operation, thereby causing the base to collide with the ground and generate a large noise. This solves the problem that the height of the four legs of the CNC gantry boring and milling machine cannot be adjusted during use as proposed in the background technology. When the ground is uneven, the CNC gantry boring and milling machine will shake during operation, causing the CNC gantry boring and milling machine to collide with the ground, thereby generating noise and affecting the health of the operator.
[0019] 2. The CNC gantry boring and milling machine with a noise reduction device is provided with a shock absorbing unit, and the vibration generated during the operation of the CNC gantry boring and milling machine is reduced by a shock absorbing spring and a damping rod, thereby further reducing the noise.
