Description

Technical Field

[0001] This utility model relates to the field of jack technology, and in particular to a horizontal jack for large CNC machining. Background Technology

[0002] Large gantry milling machines on the market, usually purchased directly from equipment manufacturers, typically lack this device. However, when setting up and installing large workpieces on gantry milling machines, it's difficult to ensure the workpiece is immediately parallel to the X-axis. This requires manual intervention using iron bars or other impact-forced tools to strike and impact the workpiece until it's parallel to the reference point. After a period of use, the machine's lead screws and axis guideways may loosen, leading to decreased displacement accuracy and inaccurate machining data. Workers expend significant physical strength during workpiece setup and installation, and with heavy parts, the impact tools are heavy, increasing the risk of accidents due to manual impact. Furthermore, the time-consuming process—ranging from 30 minutes to 1-2 hours—is a major drawback for installing workpieces on large equipment. Utility Model Content

[0003] The purpose of this invention is to provide a horizontal jack for large CNC machining, in order to solve the problem of long time consumption when adjusting the workpiece to be parallel with the X-axis on existing large gantry milling machines.

[0004] This utility model provides a horizontal jack for large CNC machining, including a fixing device, a connecting mechanism at the lower end of the fixing device, and a lifting screw at the middle of the fixing device. The lifting screw passes through the fixing device, and the fixing device and the lifting screw are provided with threads at the connection points. The lifting screw engages with the threads, the ejector end of the lifting screw abuts against the workpiece, and the rotating end of the lifting screw is provided with a driving mechanism.

[0005] The aforementioned large CNC machining horizontal jack is used by fixing the fixing device on the machine tool worktable and abutting the ejector end against the side of the workpiece to be moved. The lifting screw is rotated by the drive mechanism, which lifts the workpiece and moves it. The entire process only requires operating the drive mechanism, which is simple and fast compared to using impact tools.

[0006] Furthermore, the fixing device is provided with a first support mechanism near the outer side of the thread.

[0007] Furthermore, the ejector end of the lifting screw is provided with a support block, the outer diameter of which is larger than the outer diameter of the lifting screw.

[0008] Furthermore, the connecting mechanism is a fastening bolt.

[0009] Furthermore, the fixing device is provided with a second support mechanism in the middle that is connected to the lifting screw.

[0010] Furthermore, both the first support mechanism and the second support mechanism are bearings.

[0011] Furthermore, the driving mechanism is a crank.

[0012] Furthermore, the drive mechanism includes a mounting housing fixedly connected to the fixing device, a driven gear connected to the lifting screw, a driving gear connected to the driven gear, and a drive motor connected to the driving gear.

[0013] Furthermore, the ejector end of the lifting screw is provided with a transfer mechanism, and the transfer mechanism is provided with a clamping mechanism.

[0014] Furthermore, the clamping mechanism is a hydraulic chuck. Attached Figure Description

[0020] Please see Figures 1 to 3 This utility model provides a large-scale horizontal jack for CNC machining, including a fixing device 10, a connecting mechanism 20 located at the lower end of the fixing device 10, and a lifting screw 30 located in the middle of the fixing device 10. The lifting screw 30 passes through the fixing device 10. The fixing device 10 and the lifting screw 30 are both provided with threads (not shown in the figure). The lifting screw 30 is engaged with the threads. The ejector end of the lifting screw 30 abuts against the workpiece 100. The rotating end of the lifting screw 30 is provided with a driving mechanism 40.

[0021] When using the above-mentioned large CNC machining horizontal jack, the fixing device 10 is fixed on the machine tool worktable 200, and the ejector end is placed against the side of the workpiece 100 to be moved. The lifting screw 30 is rotated by the drive mechanism 40, so that the lifting screw 30 lifts the workpiece 100, thereby realizing the movement of the workpiece 100. The whole process only requires operating the drive mechanism 40. Compared with the use of impact tools, the operation is simple and fast.

[0022] In one embodiment of this utility model, please refer to Figure 1 The fixing device 10 is provided with a first support mechanism 50 near the outer side of the thread, which is used to support the contact position between the lifting screw 30 and the fixing device 10, thereby improving the stability of the lifting screw 30. Specifically, the first support mechanism 50 can be a bearing, so as to support both ends of the lifting screw 30 without affecting the rotation of the lifting screw 30.

[0023] In one embodiment of this utility model, the ejector end of the lifting screw 30 is provided with a support block 60, the outer diameter of which is larger than the outer diameter of the lifting screw 30. This increases the contact area between the lifting screw 30 and the workpiece 100, reduces the pressure on the contact surface, and prevents damage to the end of the lifting screw 30 or the workpiece 100.

[0024] In one embodiment of this utility model, the connecting mechanism 20 is a fastening bolt, which is used to fix the fixing device 10 to the machine tool worktable 200.

[0025] In one embodiment of the present invention, the middle part of the fixing device 10 is provided with a second support mechanism 70 connected to the lifting screw 30. Specifically, the second support mechanism 70 can be a bearing, so as to support the middle part of the lifting screw 30 without affecting the rotation of the lifting screw 30.

[0026] In one embodiment of this utility model, the drive mechanism 40 is a crank handle. In use, the operator manually cranks the lead screw 30 to achieve fine adjustment of the position of the workpiece 100.

[0027] In one embodiment of this utility model, the drive mechanism 40 includes a mounting shell (not shown) fixedly connected to the fixing device 10, a driven gear (not shown) connected to the lifting screw 30, a driving gear (not shown) connected to the driven gear, and a drive motor (not shown) connected to the driving gear. With the above structural design, only a PLC controller needs to be installed to control the forward and reverse rotation of the drive motor, thereby realizing the lifting and retraction of the lifting screw 30.

[0028] In one embodiment of this utility model, the ejector end of the lifting screw 30 is provided with a transition mechanism (not shown in the figure), and the transition mechanism is provided with a clamping mechanism (not shown in the figure). For example, an installation tube with a threaded hole can be provided. When the clamping mechanism needs to be installed, a plug with a threaded hole can be provided on the clamping mechanism, and the connection between the two can be achieved by tightening bolts and nuts. The clamping mechanism can be replaced at will.

[0029] In one embodiment of this utility model, the clamping mechanism is a hydraulic chuck, which fixes the workpiece 100 by clamping and drives the workpiece to make slight up and down adjustments.

[0030] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
