Description

Technical Field

[0001] The utility model relates to the field of medical instrument processing, in particular to a multi-axis tapping device. Background Art

[0002] Medical devices broadly refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body, including the required computer software. At present, the common medical devices in hospitals include operating tables, hospital beds, operating lights, monitors, anesthesia machines, ventilators, blood cell analyzers, differentiation analyzers, microplate readers, plate washers, urine analyzers, ultrasound machines, medical trolleys, etc. Taking a medical trolley as an example, in daily emergency or nursing work in a hospital, a trolley is usually needed to place various medicines, medical instruments or medical equipment, so as to transfer these items to the required place. During the processing of the trolley, it is necessary to tap the components of the trolley, such as tapping the preset holes of the support column of the medical trolley, so as to install fasteners, thereby realizing the connection between different components of the medical trolley. At present, the tapping process is generally carried out using a tapping machine, such as the tapping machine disclosed with publication number CN207840328U, but this type of tapping machine can only tap one hole at a time, and the support column involves tapping multiple holes at both ends. In this case, after tapping a hole, the staff needs to remove the support column, reposition the support column and then tap it, and after processing one end, it is necessary to flip and repeat the operation. The overall operation is cumbersome and inefficient. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0024] Reference Figures 1 to 4The utility model provides a multi-axis tapping device, comprising a chassis 1, a tapping mechanism 2 disposed on the chassis 1, a driving mechanism 3 disposed on the chassis 1 for driving the tapping mechanism 2, a positioning mechanism 4 disposed on the chassis 1, and a positioning and pushing mechanism 5 for pushing a workpiece. In this embodiment, the driving mechanism 3, the multi-axis device 22, and the positioning mechanism 4 are disposed in sequence. The tapping mechanism 2 includes a tapping seat 21 disposed on the chassis 1, and a multi-axis device 22 disposed on the tapping seat 21. The multi-axis device 22 includes an adjustment bracket 221 and a drill clamp 222 arranged on the adjustment bracket 221, so that the position of the drill clamp 222 can be flexibly adjusted according to the workpiece to be processed. The drill clamp 222 is set in accordance with the number of holes to be processed. In this embodiment, the workpiece (medical trolley support column) processed has six holes, so 6 drill clamps 222 are set accordingly. At the same time, the position of the drill clamp 222 needs to be set corresponding to the hole position. The specifications of the support column are various, and the shape has many shapes such as elliptical, square, polygonal, etc. In specific implementation, adaptive adjustment can be made according to the above examples. In specific implementation, the multi-axis device 22 can be set to be movable (for example, driven by an electric lead screw 55), so that the position can be flexibly adjusted, which is convenient for different processing requirements and can also realize feeding movement during the processing process.

[0025] The positioning mechanism 4 includes a first positioning assembly 41 disposed on the chassis 1, a lifting assembly 42 disposed on the chassis 1, a rotating assembly 43 connected to the lifting assembly 42, and a second positioning assembly 44 connected to the rotating assembly 43. Since the support column has a certain length, two positioning assemblies are provided to position the workpiece at two positions.

[0026] The first positioning assembly 41 and the second positioning assembly 44 both include a parallel opening and closing type air gripper 411, a first positioning member 412 connected to the output end of the parallel opening and closing type air gripper 411, and a second positioning member 413 disposed on the parallel opening and closing type air gripper, wherein the parallel opening and closing type air gripper 411 of the first positioning assembly 41 is disposed on a bracket. The parallel opening and closing type air gripper 411 has two output ends, and therefore two first positioning members 412 are disposed, the two first positioning members 412 clamp the workpiece from both sides for position limiting, the second positioning member 413 is used to support the workpiece (i.e., the first positioning member 412 and the second positioning member 413 realize radial position limiting of the workpiece), the first positioning member 412 and the second positioning member 413 are both provided with a positioning portion 544 matching the shape of the workpiece, and the first positioning member 412 and the second positioning member 413 can be replaced in a specific implementation to adapt to workpieces with different shapes and contours.

In the initial state, the first positioning assembly 41 and the second positioning assembly 44 are located at the same height, and the lifting drive 423 drives the rotating assembly 43 and the second positioning assembly 44 to rise, so that the second positioning assembly 44 is all higher than the first positioning assembly 41. At this time, the rotating assembly 43 can drive the second positioning assembly 44 to rotate. Since the second positioning assembly 44 is higher than the first positioning assembly 41, the first positioning assembly 41 will not cause interference during the rotation process. In this embodiment, the lifting drive 423 uses a cylinder.

[0028] The rotating assembly 43 includes a rotating seat 431 disposed on the lifting platform 422, a rotating driving member 432 disposed on the rotating seat 431, a rotating platform 433 connected to the rotating driving member 432, and the second positioning assembly 44 is disposed on the rotating platform 433.

When the pushing driving member 56 drives the lead screw 55, the pushing assembly 54 moves in the horizontal direction, so that the workpiece can be pushed to one side of the multi-axis device 22, and the length direction (axial direction) of the workpiece can be limited.

[0030] The push assembly 54 includes a connection seat, a push rod 541 connected to the connection seat, the push rod 541 passes through the wall of the chassis 1 and extends to the outside of the chassis 1, and one end of the push rod 541 extending out of the chassis 1 is connected to a push plate 542. Two push rods 541 are provided to ensure stability during movement.

In this embodiment, the processed medical trolley support column is a hollow structure, and the inner wall has a plurality of connection structures, and the shape of the positioning portion 544 matches it, that is, the positioning portion 544 can be inserted into the end of the support column.

[0032] The driving mechanism 3 includes a driving seat 31 arranged on the chassis 1, a transmission 32 arranged on the driving seat 31, and a driving motor 33 arranged on the transmission 32. The driving motor 33 is connected to the transmission 32 through a synchronous pulley set, and the transmission 32 is connected to the multi-axis device 22.

[0033] The chassis 1 is provided with a controller 6 having a touch screen for convenient operation by staff.

[0034] During operation, the workpiece to be processed is first placed on the first positioning assembly 41 and the second positioning assembly 44, and then the pusher 543 of the push assembly 54 is inserted into the end of the workpiece to push the workpiece to the predetermined position, and the drive mechanism 3 drives the multi-axis device 22 to tap the preset position of the workpiece. After the tapping is completed at one end of the workpiece, the first positioning assembly 41 releases the space, the lifting assembly 42 lifts the workpiece upward, the rotating assembly 43 rotates the workpiece 180°, and then the lifting assembly 42 is reset, the first positioning assembly 41 clamps the workpiece again, and the drive mechanism 3 drives the multi-axis device 22 to repeat the tapping operation. After the tapping is completed, the first positioning assembly 41 and the second positioning assembly 44 are reset, and the workpiece is taken away, that is, the tapping process of one workpiece is completed, and then the above operation is repeated to process the next workpiece.

[0035] The first positioning component 41, the second positioning component 44 and the positioning and pushing mechanism 5 provided in the utility model can quickly position the workpiece. With the cooperation of the multi-axis device 22, tapping operations at multiple positions can be achieved at one time without frequent repeated positioning, which simplifies the tapping operation, improves work efficiency, reduces labor intensity, and saves production costs. At the same time, with the cooperation of the lifting component 42 and the rotating component 43, the workpiece can be flipped 180°, thereby completing the tapping at both ends of the workpiece, further improving work efficiency.
