Technical Field

[0001] The utility model relates to the technical field of tool magazine tool-taking drive structures, in particular to a tool-taking drive structure for a translation column. Background Art

[0002] The storage tool magazine has the advantage of storing a large number of tools. In order to realize automatic tool retrieval, a tool retrieval mechanism is set up in the storage tool magazine. The tool retrieval mechanism generally adopts a screw-nut transmission system to realize the horizontal movement. However, since the translation column is under a large load during the movement of the tool retrieval, the screw-nut transmission system will reduce the speed due to the need to overcome the large friction and load force, resulting in a slower tool retrieval action, thereby affecting the efficiency of the tool retrieval action.

[0034] like Figures 1 to 6The illustrated driving structure for the translation column 01 to move the tool is provided between the base frame 00 and the translation column 01 and includes:

[0035] The drive assembly is located on the center plane of the translation column 01 and includes a meshing rack 1 and gear 2, and a drive motor 3 for driving the gear 2 to rotate;

[0036] Two sets of sliding assemblies 4 are symmetrically arranged on both sides of the rack 1 along the sliding direction, including guide rails 41 and sliders 42 that slide with the guide rails 41;

[0037] The driving motor 3 is fixed on the support seat 7 on the rear side of the translation column 01, and its driving end is connected to the gear 2. The rack 1 is fixed on the base frame 00, and one side of the rack 1 is provided with teeth that cooperate with the gear 2.

[0038] By using the meshing of gear 2 and rack 1, precise linear motion control can be provided. Compared with the traditional screw-nut transmission system, the gear 2 and rack 1 transmission generally has higher transmission efficiency, and the gear 2 and rack 1 transmission can respond quickly, reducing the motion delay caused by the friction and load force in the screw-nut system, thereby speeding up the knife removal action.

[0039] In the present invention, the translation column 01 needs to move a long distance. In order to reduce the difficulty of processing the rack 1 and ensure transmission accuracy and stability, preferably, the rack 1 adopts a multi-section splicing structure.

[0040] In the preferred embodiment, a first positioning block 5 for mounting the rack 1 is provided on the base frame 00; a first step surface 51 and a second step surface 52 are provided on the positioning block, the height of the first step surface 51 is lower than the height of the second step surface 52, and the rack 1 is mounted on the second step surface 52.

[0041] By setting step surfaces of different heights, a precise installation position can be provided for the rack 1 to ensure the correct alignment and positioning of the rack 1, which is crucial for the meshing accuracy of the gear 2 and the rack 1.

[0042] In the preferred embodiment of the present utility model, the base frame 00 is further provided with a second positioning block 6 for mounting the guide rail 41;

[0043] A mounting groove 61 is provided on the top surface of the second positioning block 6, and the guide rail 41 is embedded in the mounting groove 61. A calibration groove 62 is provided on the side of the mounting groove 61 away from the rack 1. The calibration groove 62 is connected to the mounting groove 61, and a pressure block 63 is provided in the calibration groove 62. The pressure block 63 abuts against the side of the guide rail 41 away from the rack 1.

[0044] By providing a mounting groove 61 on the top surface of the second positioning block 6, the precise embedding of the guide rail 41 can be ensured. The design of the calibration groove 62 enables the pressure block 63 to apply appropriate pressure to the guide rail 41, ensuring a tight fit between the guide rail 41 and the mounting groove 61, reducing vibration and displacement under high load or dynamic conditions, thereby enhancing the stability of the entire structure.

[0045] As a preferred embodiment of the above embodiment, the opening of the calibration groove 62 faces upward, and the depth of the calibration groove 62 is greater than the depth of the mounting groove 61; the side of the calibration groove 62 away from the mounting groove 61 is inclined to form a push surface 621, and the pressure block 63 is provided with a guide surface 631 that cooperates with the push surface 621; the cross-sectional width of the guide rail 41 is greater than the cross-sectional width of the mounting groove 61, and the pressure block 63 abuts against the side of the guide rail 41.

[0046] The guide surface 631 on the pressing block 63 cooperates with the pushing surface 621 to ensure the precise installation of the guide rail 41, and the pressing block 63 can apply appropriate pressure to the guide rail 41 to ensure a tight fit between the guide rail 41 and the mounting groove 61, thereby reducing looseness or vibration during operation.

[0047] In a preferred embodiment of the present utility model, an adjustment plate 8 is provided at the bottom of the support seat 7, and a center hole is provided at the center of the adjustment plate 8 for the drive shaft of the drive motor 3 to pass through; a first lubrication wheel 9 and a second lubrication wheel 10 are provided on the adjustment plate 8 along the transmission direction, and the outer circumferential surfaces of the first lubrication wheel 9 and the second lubrication wheel 10 are both provided with teeth meshing with the rack 1.

[0048] The arrangement of the first lubrication wheel 9 and the second lubrication wheel 10, and the meshing of the teeth on their outer circumferential surfaces with the rack 1, can continuously lubricate the rack 1, reduce friction and wear, and extend the service life of the rack 1 and the gear 2. Good lubrication can also reduce the friction coefficient between the tooth surfaces, improve the transmission efficiency, and at the same time suppress the temperature rise caused by friction, thereby achieving the effect of cooling the tooth surfaces.

[0049] As a preferred embodiment of the above embodiment, the support base 7 is provided with an elongated hole for mounting the adjustment plate 8, and the elongated hole is arranged perpendicular to the rack 1. The design of the elongated hole allows the adjustment plate 8 to move axially in a direction perpendicular to the rack 1. This allows the position of the adjustment plate 8 to be adjusted according to different installation requirements, ensuring the meshing accuracy of the rack 1 and the gear 2, thereby improving the operating accuracy of the entire transmission system.

[0050] To ensure effective lubrication, radial through-holes are provided on the outer cylindrical surfaces of the first and second lubrication wheels 9, 10. These through-holes act as channels for the lubricant, allowing the lubricant to flow through the through-holes to the tooth surfaces of rack 1, ensuring that the lubricant is evenly distributed across the meshing surfaces of rack 1 and gear 2.

[0051] When lubricating rack 1 and gear 2, the lubricating oil flows downward along the toothed grooves of rack 1 through the meshing gap. Therefore, an oil pan is provided below the chassis 00. The oil collected in the oil pan prevents it from accumulating at the bottom of the equipment, reducing the risk of corrosion or damage to the equipment due to prolonged contact with the oil. Furthermore, the waste oil collected in the oil pan can be recycled and reused, reducing resource waste.

[0052] Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and the specification are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
