Description

Technical Field

[0001] This invention relates to the field of machine tool processing technology, and in particular to an automatic material lifting device. Background Technology

[0002] CNC machine tools are flexible and high-efficiency automated machine tools that can effectively solve the problems of machining complex, precise, small-batch, and multi-variety parts. They represent the development direction of modern machine tool control technology. The core of CNC machine tools is the CNC device. Modern CNC devices generally adopt the CNC (Computer Numerical Control) form and are a typical mechatronics product.

[0003] Before using a CNC machine tool, the workpiece needs to be clamped in a fixture for loading, and then the workpiece is processed. After the previous workpiece is processed, the operator needs to remove the processed workpiece from the fixture and then manually place the new workpiece on the fixture. In order to ensure clamping accuracy, the operator usually needs to use a jig auxiliary device to clamp the workpiece on the fixture. However, when the processing time of the workpiece is short, the operator needs to load the workpiece frequently. However, since the process of loading the workpiece using the jig auxiliary device is cumbersome, the loading time accounts for a high proportion of the processing time. This not only affects the processing efficiency, but also increases the labor intensity of the operator. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes an automatic material lifting device, which can ensure the efficiency of processing workpieces and reduce the labor intensity of operators.

[0005] An automatic material lifting device according to an embodiment of the present invention includes: a limiting component, the limiting component including a limiting member, the limiting member being provided with a limiting groove and a first opening, the first opening being disposed at the top of the limiting member and communicating with the limiting groove, the limiting groove being capable of accommodating multiple workpieces to be processed; a lifting component, the lifting component being disposed on one side of the limiting member, the lifting component being capable of driving the workpieces to be processed in the limiting groove to move and causing one part of the workpiece to be processed to extend out from the first opening; and a positioning component, the positioning component including a positioning element, the positioning element being disposed on the limiting member near the first opening, the positioning element being used to laterally push and position the workpiece to be processed extending out from the first opening.

[0006] The automatic material lifting device according to embodiments of the present invention has at least the following beneficial effects:

[0007] The limiting groove of the limiting component can accommodate multiple workpieces to be processed. The operator can place multiple workpieces into the limiting groove. The lifting component can drive one part of the workpiece located in the limiting groove to extend out from the first opening, and the length of the extension can be controlled. The positioning component of the positioning part can push the workpiece laterally and make it abut against the inner wall of the limiting groove. The friction between the workpiece and the inner wall of the limiting groove, and the friction between the positioning component and the workpiece, fix the position of the workpiece extending from the first opening relative to the limiting component, facilitating processing of the extended portion. After processing of the workpiece extending from the first opening is completed, the operator controls the positioning component to release the workpiece and remove it. The lifting component can then drive the next workpiece to extend out from the first opening, repeating the steps of positioning, processing, and removing workpieces. The process continues until all workpieces in the limiting slots have been processed. The operator can then place multiple workpieces into the limiting slots, which can accommodate multiple workpieces, reducing the number of times the operator needs to load materials and thus reducing their workload. Because the limiting slots can hold multiple workpieces, the operator can place them into the slots and drive the workpieces out of the first opening via the lifting component, achieving automatic lifting. The length of the workpieces extending from the first opening can be controlled, and the workpieces can be fixed by the positioning component. Therefore, this automatic lifting device can accommodate multiple workpieces and has a high degree of automation, enabling continuous lifting and fixing of multiple workpieces to achieve continuous production processing, ensuring processing efficiency and reducing the operator's workload.

[0031] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0032] The following is for reference. Figures 1 to 7 An automatic material lifting device according to an embodiment of the present invention is described.

[0033] like Figures 1 to 7 As shown, the automatic material lifting device according to an embodiment of the present invention includes a limiting component 100, a lifting component 200, and a positioning component. The limiting component 100 includes a limiting member 110, which has a limiting groove 114 and a first opening 111. The first opening 111 is located at the top of the limiting member 110 and communicates with the limiting groove 114. The limiting groove 114 can accommodate multiple workpieces 10 to be processed. The lifting component 200 is located on one side of the limiting member 110. The lifting component 200 can drive the workpieces 10 to be processed in the limiting groove 114 to move and cause one part of the workpiece 10 to extend out from the first opening 111. The positioning component includes a positioning component 300, which is located on the limiting member 110 near the first opening 111. The positioning component 300 is used to push and position the workpiece 10 extending out from the first opening 111.

[0034] The limiting groove 114 of the limiting member 110 can accommodate multiple workpieces 10 to be processed. The operator can place multiple workpieces 10 into the limiting groove 114. The lifting component 200 can drive one part of the workpiece 10 located in the limiting groove 114 to extend out from the first opening 111, and can control the length of the workpiece 10 extending out from the first opening 111. The positioning component 300 of the positioning member can push the workpiece 10 to the side and make the workpiece 10 abut against the inner wall of the limiting groove 113, so that the workpiece 10 and the limiting groove 113 can be connected. The friction between the inner walls of 14 and the friction between the positioning component and the workpiece 10 are used to fix the position of the workpiece 10 extending from the first opening 111 relative to the limiting component 110, so as to facilitate the processing of the extended part of the workpiece 10. After the processing of the workpiece 10 extending from the first opening 111 is completed, the operator controls the positioning component 300 to release the workpiece 10 to remove it. The lifting component 200 can continue to drive the next workpiece 10 to extend from the first opening 111, and repeat the positioning and processing. The process of processing and removing the workpieces 10 continues until all workpieces 10 in the limiting slots 114 have been processed. The operator can place multiple workpieces 10 into the limiting slots 114, which can accommodate multiple workpieces 10, reducing the number of times the operator needs to load materials and thus reducing the operator's workload. Because the limiting slots 114 can accommodate multiple workpieces 10, the operator can place multiple workpieces 10 into the limiting slots 114, and the lifting assembly 200 will drive the workpieces... The workpiece 10 extends out from the first opening 111 to achieve automatic lifting of the workpiece 10. The length of the workpiece 10 extending out from the first opening 111 can be controlled. The workpiece 10 can be fixed by the positioning component 300. Therefore, the automatic lifting device can accommodate multiple workpieces 10 and has a high degree of automation. It can complete the continuous lifting and fixing of multiple workpieces 10 to achieve continuous production and processing of the workpieces 10, ensure the efficiency of processing the workpieces 10, and reduce the labor intensity of the operators.

[0035] Specifically, multiple workpieces 10 are stacked vertically within the limiting groove 114. The lifting assembly 200 drives the workpiece 10 located further away from the first opening 111 to move toward the first opening 111, thereby simultaneously moving multiple workpieces 10, so that the workpiece 10 closer to the first opening 111 can extend out from the first opening 111.

[0036] Reference Figure 1 , Figure 2 and Figure 4It is understood that the positioning component 300 includes a second driving member 310 and a pressing block 320. The side of the limiting member 110 is provided with a third opening 113, which communicates with the limiting groove 114. The pressing block 320 is slidably disposed at the third opening 113. The second driving member 310 is drivenly connected to the pressing block 320 and can drive the pressing block 320 to extend from the third opening 113 into the limiting groove 114 and abut against the workpiece 10 to be processed.

[0037] The second driving member 310 pushes the pressure block 320 from the side of the limiting member 110 into the limiting groove 114 and pushes the workpiece 10 to be processed to move, so that the end of the workpiece 10 away from the pressure block 320 abuts against the inner wall of the limiting groove 114. The position of the workpiece 10 is fixed by the friction between the pressure block 320 and the workpiece 10 and the friction between the inner wall of the limiting groove 114 and the workpiece 10.

[0038] Specifically, the positioning component 300 is disposed near the first opening 111 of the limiting member 110, and the third opening 113 is disposed on the side of the limiting member 110 and extends to the top surface of the limiting member 110, so that the workpiece 10 passing through the first opening 111 can be fixed by the second driving member 310 and the pressure block 320.

[0039] Specifically, the second driving component 310 includes a second lifting cylinder and a connecting rod. The second lifting cylinder is driven to connect with the connecting rod and can drive the connecting rod to move up and down. The pressure block 320 is sleeved on the connecting rod, and the bottom wall of the pressure block 320 can abut against the connecting rod. A fixing bolt is provided at the end of the connecting rod away from the second lifting cylinder. The fixing bolt can abut against the top wall of the pressure block 320, thereby fixing the pressure block 320 and the connecting rod.

[0040] Reference Figures 1 to 4 It is understood that the positioning component 300 also includes a push block 330, which is provided with a first inclined surface 331, and a pressing block 320 is provided with a second inclined surface 321 that cooperates with the first inclined surface 331. The first inclined surface 331 and the second inclined surface 321 abut against each other. The second driving member 310 is connected to the push block 330 and can drive the push block 330 to move so as to drive the pressing block 320 to move.

[0041] Specifically, a first inclined surface 331 is provided on one side of the push block 330, and a second inclined surface 321 is provided on one side of the pressure block 320. The first inclined surface 331 and the second inclined surface 321 are configured to cooperate with each other. The second driving member 310 is connected to the push block 330 and can move the push block 330 up and down. (Refer to...) Figure 4The second inclined surface 321 is located above the first inclined surface 331. The second driving member 310 drives the push block 330 to move downward, so that the first inclined surface 331 of the push block 330 abuts against the second inclined surface 321 of the pressure block 320, and the first inclined surface 331 presses against the second inclined surface 321, so that the pressure block 320 moves in the horizontal direction, thereby enabling the pressure block 320 to move in the direction of the workpiece 10 to be processed and press the workpiece 10 against the inner wall of the limiting groove 114.

[0042] Specifically, the slopes of the first inclined surface 331 and the second inclined surface 321 are equal; the end of the pressing block 320 away from the first inclined surface 331 has an abutment surface 322, and the pressing block 320 abuts against the workpiece 10 through the abutment surface 322. The pressing block 320 may have several textures on the abutment surface 322 to reduce the contact area between the pressing block 320 and the workpiece 10, thereby increasing the friction between the pressing block 320 and the workpiece 10; the pressing block 320 may have an elastic material on the abutment surface 322, or the pressing block 320 may be made of an elastic material, thereby reducing the damage caused by the collision between the pressing block 320 and the workpiece 10, and protecting the pressing block 320 and the workpiece 10.

[0043] Reference Figure 1 , Figure 2 and Figure 6 It is understood that the automatic material lifting device also includes a bridge plate 400, on which a first groove 410 and a second groove 420 are provided. The push block 330 is slidably disposed in the first groove 410 in the vertical direction, and the pressure block 320 is slidably disposed in the second groove 420 in the horizontal direction.

[0044] The pressing block 320 and the pushing block 330 can be placed in the first groove 410 and the second groove 420 respectively. The first groove 410 extends vertically and the second groove 420 extends horizontally. The pushing block 330 can be slidably disposed in the first groove 410 in the vertical direction, and the pressing block 320 can be slidably disposed in the second groove 420 in the horizontal direction. The first groove 410 and the second groove 420 can limit the direction of movement of the pressing block 320 and the pushing block 330.

[0045] Specifically, a connection port 430 is also provided on the bridge plate 400. The limiting member 110 passes through the connection port 430 and is connected to the bridge plate 400. One end of the first groove 410 is connected to the second groove 420, and the other end of the first groove 410 is connected to the third opening 113 of the limiting member 110, so that the pressure block 320 can move between the second groove 420 and the third opening 113.

[0046] Reference Figure 1 , Figure 2 and Figure 6It is understandable that a sliding groove 421 is provided on the inner wall of the second groove 420, and a slider 323 is provided on the pressure block 320. The slider 323 is slidably disposed in the sliding groove 421.

[0047] When the pressure block 320 slides within the second groove 420, the slider 323 of the pressure block 320 slides within the slide groove 421. By providing the slider 323 on the outer wall of the pressure block 320, the sliding direction of the pressure block 320 can be restricted by the slider 323 and the slide groove 421. Specifically, the slider 323 is provided on the side wall of the pressure block 320, and the slide groove 421 is provided on the inner side wall of the second groove 420. When the slider 323 slides within the slide groove 421, the slider 323 can slide within the slide groove 421. The upper and lower inner walls of the 1-inner wall abut against each other to limit the sliding block 323 to slide along the extension direction of the groove 421, thereby limiting the pressure block 320 to slide along the extension direction of the groove 421. The extension direction of the groove 421 is horizontal and is set in the same direction as the extension direction of the second groove 420. Multiple sliding blocks 323 can be provided, and multiple sliding blocks 323 are respectively provided on both sides of the pressure block 320. Correspondingly, multiple grooves 421 are also provided.

[0048] Reference Figure 1 , Figure 2 and Figure 6 It is understandable that the positioning component 300 is also provided with an elastic element 340, which is connected to the inner wall of the slider 323 and the groove 421.

[0049] The elastic element 340 is disposed in the slide groove 421 and is located between the slider 323 and the inner wall and is connected to the inner wall of the slide groove 421. When the pressure block 320 starts to move from the initial position, the pressure block 320 will compress or stretch the elastic element 340. The elastic element 340 will drive the pressure block 320 to move in the direction where the pressure block 320 is in the initial position. The spring element can be a spring, and the two ends of the spring are respectively connected to the inner wall of the slider 323 and the slide groove 421.

[0050] Specifically, when the push block 330 moves downward, it pushes the pressure block 320 toward the workpiece 10. The pressure block 320 compresses the elastic element 340, and the elastic element 340 continuously applies a force to the pressure block 320 away from the workpiece 10. When the push block 330 moves upward, the elastic element 340 can push the pressure block 320 so that the pressure block 320 moves toward the push block 330, thereby ensuring that the first inclined surface 331 is always in contact with the second inclined surface 321. The elastic element 340 can be a spring, and the spring is always in a compressed state.

[0051] Reference Figure 7It is understandable that in order to increase the working efficiency of the automatic lifting device, multiple limit components 100 are provided, which can increase the number of workpieces 10 that the automatic lifting device can accommodate. Correspondingly, multiple positioning components are provided to cooperate with multiple limit components 100.

[0052] Specifically, multiple limiting components 100 and multiple positioning components are all arranged on the bridge plate 400. The lifting component 200 can drive the workpiece 10 to be processed in the limiting member 110 of each limiting component 100. When all the workpieces 10 to be processed on the previous limiting member 110 are processed, the lifting component 200 can drive the workpieces 10 to be processed on the limiting member 110 of the next limiting component 100 to move. During this time, the operator can load the previous limiting member 110 to improve processing efficiency. There can also be multiple lifting components 200 to cooperate with multiple limiting components 100 and positioning components. Multiple lifting components 200 can lift the workpieces 10 to be processed on multiple limiting members 110 to improve processing efficiency.

[0053] Reference Figure 1 and Figure 2 It is understood that there are two positioning components 300, namely a first positioning component 301 and a second positioning component 302. The first positioning component 301 can push the workpiece 10 to move in a first direction, and the second positioning component 302 can push the workpiece 10 to move in a second direction. There is an angle between the first direction and the second direction.

[0054] The pressure block 320 of the first positioning component 301 can push the workpiece 10 to move in the first direction, so that the workpiece 10 abuts against one side wall of the limiting groove 114 and the pressure block 320 of the first positioning component 301. The pressure block 320 of the first positioning component 301 can push the workpiece 10 to move in the first direction, so that the workpiece 10 abuts against the other side wall of the limiting groove 114 and the pressure block 320 of the second positioning component 302. Since there is an angle between the first direction and the second direction, the first positioning component 301 and the second positioning component 302 can limit the position of the workpiece 10 in the horizontal direction, thereby improving the stability of pressing the workpiece 10.

[0055] Specifically, the first positioning component 301 can push its pressing block 320 to move towards the first horizontal direction, and the second positioning component 302 can push its pressing block 320 to move towards the second horizontal direction. The first horizontal direction and the second horizontal direction are set perpendicular to each other. By pressing the workpiece 10 from the first horizontal direction and the second horizontal direction respectively through the first positioning component 301 and the second positioning component 302, the stability of the positioning components in fixing the workpiece 10 is improved. The workpiece 10 is cuboid, and the cross-section of the limiting groove 114 is square. The first positioning component 301 and the second positioning component 302... Positioning components 302 are respectively disposed on adjacent sides of the workpiece 10 to be processed. The pressing blocks 320 of the first positioning component 301 and the second positioning component 302 abut against the two adjacent sides of the workpiece 10 to be processed, thereby pushing the workpiece 10 to be processed to move, so that the other two adjacent sides of the workpiece 10 abut against the two inner sidewalls adjacent to the limiting groove 114, so that the first positioning component 301 and the second positioning component 302 can limit the position of the workpiece 10 in the horizontal direction, avoid the workpiece 10 from having a position in the horizontal direction during the processing, and improve the processing quality.

[0056] Reference Figure 5 It is understood that a guide groove 115 is provided on the side of the limiting member 110, the guide groove 115 is connected to the limiting groove 114, and one end of the guide groove 115 extends to the bottom of the limiting member 110; the lifting assembly 200 includes a first driving member 210 and a lifting member 220, the first driving member 210 is drivenly connected to the lifting member 220, and can drive the lifting member 220 to extend from the guide groove 115 into the limiting groove 114 and push the workpiece 10 to be processed to move.

[0057] The side of the limiting member 110 is provided with a guide groove 115, which is connected to the limiting groove 114 so that the outside world is connected to the limiting groove 114. The first driving member 210 can drive the lifting member 220 to extend from the guide groove 115 into the limiting groove 114, so that the lifting member 220 can abut against the workpiece 10 to be processed in the limiting groove 114 and push the workpiece 10 to be processed to move. The guide groove 115 extends to the bottom of the limiting member 110, so that the first driving member 210 can drive the lifting member 220 to move to the bottom of the limiting member 110 and extend from the guide groove 115 into the limiting groove 114, so that the lifting member 220 can move to the bottom of the limiting groove 114, so that the lifting member 220 can push all the workpieces 10 to be processed in the limiting groove 114.

[0058] Specifically, the limiting groove 114 extends vertically, and multiple workpieces 10 can be stacked vertically within the limiting groove 114. The guide groove 115 also extends vertically. The first driving member 210 drives the lifting member 220 to extend into the limiting groove 114 and abut against the workpiece 10 that is farther away from the first opening 111 among the multiple workpieces 10. By pushing the workpiece 10 upward, multiple workpieces 10 can move upward simultaneously, and the workpiece 10 closest to the first opening 111 is controlled to extend out from the first opening 111.

[0059] Specifically, the lifting component 220 is a lifting cutter bar, which is cylindrical and contacts the workpiece 10 to be processed through an arc surface, so as to reduce the damage of the lifting component 220 to the workpiece 10 to be processed.

[0060] Reference Figure 1 and Figure 5 It is understood that the limiting component 100 also includes a support member 120; the guide groove 115 extends to the bottom of the limiting member 110 at one end away from the first opening 111 and forms a second opening 112; the support member 120 is detachably disposed at the bottom of the limiting member 110; the support member 120 is provided with a support groove 121 on the side facing the limiting member 110; the support groove 121 can communicate with the limiting groove 114 through the second opening 112; the support groove 121 is used to support the workpiece 10 to be processed.

[0061] The support member 120 is disposed at the bottom of the limiting member 110. Since the support member 120 has a support groove 121 on the side facing the limiting member 110, and the guide groove 115 extends to the bottom of the limiting member 110 away from the first opening 111 and forms a second opening 112, the first workpiece 10 to be processed placed into the limiting groove 114 from the first opening 111 can fall onto the support groove 121. Subsequent workpieces 10 are stacked one on top of the other, and all workpieces 10 are supported by the support member 120. By setting the support member 120 in conjunction with the limiting member 110, the number of workpieces 10 that can be processed can be increased. The left and right ends of the limiting groove 114 are connected to facilitate external personnel to observe the position of the workpieces 10. Furthermore, the length of the support groove 121 is less than the length of the workpiece 10 to prevent the workpiece 10 from falling out of the support groove 121.

[0062] Specifically, the support member 120 and the limiting member 110 are detachably connected. Multiple support members 120 are provided, and the height of the support groove 121 of different support members 120 is different to adapt to different lengths of workpieces 10 to be processed. When it is necessary to support workpieces 10 of different lengths, support members 120 of different lengths can be replaced, which can increase the number of workpieces 10 that the limiting member 110 can accommodate.

[0063] Specifically, a through groove 122 is provided on the bottom wall of the support groove 121. The through groove 122 extends to the bottom of the support member 120. The through groove 122 is configured to cooperate with the lifting member 220. The first driving member 210 can drive the lifting member 220 to lift the workpiece located in the support groove 121 from inside the through groove 122.
