Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a screw seat CNC drilling and milling integrated machine. Background Art

[0002] When processing metal workpieces, it is often necessary to perform operations such as drilling, milling, and grooving on the surfaces of these workpieces. These operations require the use of drilling machines, milling machines and other equipment respectively. If there is a device that can both drill and mill the workpiece, it can save costs and reduce the equipment footprint.

[0003] Patent CN206614239U discloses a drilling and milling machine tool, including a tool lifting mechanism and a track device. A fixture seat is installed on the track device. A drilling and milling tool with a replaceable tool is installed on the tool lifting mechanism. The drilling and milling tool is arranged directly above the fixture seat. The track device drives the fixture seat to move, and the drilling and milling tool is used to perform drilling and milling operations on the workpiece clamped by the fixture seat. This equipment satisfies the requirement that one device can perform both drilling and milling operations.

[0004] However, it was found that this drilling and milling machine tool still has the following problems: this drilling and milling machine tool can only process one surface, namely the upper surface of the workpiece. After processing one surface, the workpiece needs to be re-clamped to adjust the direction. After re-clamping, multiple processes such as tool replacement and re-tooling are required. If the processing includes both threaded holes and steps and the threaded holes and steps are on different processing surfaces of the screw seats, there will be a problem of low processing efficiency.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0025] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0026] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0027] like Figure 1 to Figure 2 As shown, an embodiment of the utility model is a screw seat CNC drilling and milling machine, including a welding frame 1, a vertical platform 2 and a horizontal platform 3 are arranged inside the welding frame 1, a Z-axis track device 4 and a first sliding tool 5 controlled by the Z-axis track device 4 are arranged on the vertical platform 2, an X-axis track device 6, a Y-axis track device 7 controlled by the X-axis track device 6 and a pneumatic clamp 8 controlled by the Y-axis track device 7 are arranged on the horizontal platform 3, a screw seat 9 and a CNC panel 10 installed on the welding frame 1, the pneumatic clamp 8 is used to clamp the screw seat 9, and a second tool 11 facing the pneumatic clamp 8 is also arranged on the horizontal platform 3, and the axis of the second tool 11 is perpendicular to the axis of the first tool 5. The utility model has a structure of a multi-directional drilling and milling tool, that is, the first tool and the second tool are installed in different directions relative to the pneumatic clamp, so that different surfaces on the clamped screw seat can be directly drilled and milled. Different surfaces on the screw seat can be drilled and milled with only one clamping, and there is no need to adjust the direction and re-clamp the screw seat after processing one surface, which saves multiple processes such as tool replacement and re-tooling. This structure has the advantage of high processing efficiency.

[0028] like Figure 2 As shown, the horizontal platform 3 is also provided with a third tool 12 parallel to the axis of the second tool 11, the first tool 5 is a milling cutter, the second tool 11 is a drill, and the third tool 12 is a tap. Through the above structure, the first tool is equipped with a milling cutter and cooperates with the Z-axis track device to slide in the Z-axis direction to facilitate milling the steps of the screw seat. The threaded hole on the side of the screw seat needs to be processed, so the second tool is equipped with a drill, and the third tool parallel to the second tool is equipped with a tap. The drill is used to drill holes first and then the tap is used to tap. The processing can be completed without changing the tool head of the second tool, further improving the processing efficiency.

[0029] like Figure 3 to Figure 4As shown, the pneumatic clamp 8 includes a clamp bracket 13 and a first jacket 14 and a second jacket 15 arranged on the clamp bracket 13, a clamping portion 16 for clamping the screw seat 9 is formed between the first jacket 14 and the second jacket 15, and a pattern 17 for increasing friction with the screw seat 9 is provided on one end surface of the second jacket 15 close to the clamping portion 16. Through the above structure, the first jacket and the second jacket with the friction increasing pattern can firmly clamp the screw seat.

[0030] like Figure 3 to Figure 4 As shown, the first clamping sleeve 14 is provided with a first limiting plate 18, and the second clamping sleeve 15 is provided with a second limiting plate 19 and a third limiting plate 20. The first limiting plate 18 and the second limiting plate 19 are both used to limit the end face of the screw seat 9 away from the clamp bracket 13, and the third limiting plate 20 is used to limit the end face of the screw seat 9 close to the second tool 11. The third limiting plate 20 is also provided with a clearance groove 21 for the second tool 11 to pass through. The end face of the screw seat away from the clamp bracket is limited by the first limiting plate and the second limiting plate, and the end face of the screw seat close to the second tool is limited by the third limiting plate. All three have the effect of preventing the vibration generated during processing from causing the screw seat to separate from the clamping part, further improving the clamping effect of the pneumatic clamp on the screw seat. The clearance groove of the third limiting plate can be passed by the second tool to facilitate the processing of the threaded hole.

[0031] like Figure 6 to Figure 7 As shown, the pneumatic clamp 8 also includes a cylinder 22 and a slider 23 driven by the cylinder 22. The first clamping sleeve 14 is provided with a cavity 24 for the slider 23 to extend into. A first clamping block 25 is provided in the cavity 24. One side of the first clamping block 25 is slidably matched with the slider 23 and the other side is extended into the clamping portion 16 for clamping the screw seat 9. A first inclined surface 26 is provided on the side of the slider 23 close to the first clamping block 25. The first clamping block 25 is provided with a second inclined surface 27 matched with the first inclined surface 26. The length of the slider 23 along the driving direction of the cylinder 22 is less than the length of the first clamping block 25. The first inclined surface of the slider driven by the cylinder and the second inclined surface of the first clamping block form a displaced sliding fit, so that the first clamping member can extend into or out of the clamping portion, and the screw seat is further clamped by the first clamping block. This structure has the advantage of tighter clamping.

[0032] like Figure 5 As shown, the first inclined surface 26 is provided with a bent portion 28, and the second inclined surface 27 is provided with a T-shaped slot 29 adapted to the bent portion 28. The cooperation between the bent portion and the T-shaped slot makes the sliding cooperation between the slider and the first clamping block stable and smooth, ensuring the synchronization of the movement of the slider and the first clamping block.

[0033] like Figures 5 to 7As shown, a second clamping block 30 that is slidably matched with the slider 23 is further provided in the cavity 24, and the second clamping block 30 is located on the side of the slider 23 away from the clamping portion 16. A second clamping block that is also slidably matched with the slider is further provided, and the first clamping block and the second clamping block are distributed on both sides of the slider so that the forces on both sides of the slider are evenly applied and the sliding is smoother.

[0034] like Figure 6 to Figure 7 As shown, the inclination angle of the first inclined surface 26 is 50°-70°. The inclination angle 31 formed by the first inclined surface is between 50° and 70°. The inclination angle in this range can make the sliding fit between the slider and the first clamping block smoother, the force on the first inclined surface and the second inclined surface more uniform, and the bending part and the T-slot will not get stuck.

[0035] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
