Description

Technical Field

[0001] The present invention relates to the field of workpiece clamping devices for machine tools, and in particular to a side clamping and feeding device for plate workpieces. Background Art

[0002] In the machining industry, when machining a workpiece, first a clamping device is needed to clamp and fix the workpiece to prevent the workpiece from shifting during machining, which may lead to a reduction in machining accuracy. When machining a plate workpiece, due to the small contact area of the vertical surface on the side of the plate, especially for thin plate workpieces, when clamping and positioning, a pressing plate or clamp is usually used for clamping. The workpiece is fixed by pressing it tightly at the edge position of the plate by the jaws or the surrounding pressing plates.

[0003] Currently, a Chinese patent with publication number CN118180937A and publication date June 14, 2024, proposes a metal plate clamping device, which includes a working frame, side clamping components, a bottom plate, a baffle, a sliding plate, and a power component. The side clamping components are located on both sides of the working frame, the bottom plate is located above the side clamping components, the baffle is located on the side away from the side clamping components above the bottom plate, the sliding plate is slidably arranged on the baffle, and the power component is fixedly connected to the baffle to drive the sliding plate to move up and down.

[0004] When in use, the plate workpiece is placed on the working frame, and the side clamping components move towards the direction close to the working frame to clamp the edge of the workpiece by the baffle; or the bottom plate is moved below the plate workpiece, and the power component drives the sliding plate to move downwards to clamp the workpiece between the sliding plate and the bottom plate.

[0005] Regarding the above related technologies, when the clamping device clamps a plate workpiece, the side edge of the plate workpiece needs to extend beyond the side position of the working frame. For some plate workpieces with a small width such that the edge of the plate does not extend beyond the edge of the working area, the clamping device cannot clamp the side of the plate workpiece. Summary of the Invention

[0006] In order to enable the clamping device to clamp and fix a plate workpiece whose edge does not extend beyond the edge position of the workbench, the present invention provides a side clamping and feeding device for plate workpieces.

[0007] The present invention provides a side clamping and feeding device for plate workpieces, adopting the following technical solutions:

[0008] A side clamping and feeding device for a plate member, comprising a base, a driving assembly and a clamping plate assembly. The driving assembly is used for driving connection with the slide rail of the machine tool. The driving assembly and the clamping plate assembly are both installed on the base. The clamping plate assembly includes an upper clamping plate and a lower clamping plate. The upper clamping plate and the lower clamping plate are driven to clamp by a third driving member. The device further includes a push plate assembly, which includes a first driving member and a push plate. The push plate is slidably arranged between the upper clamping plate and the lower clamping plate along the width direction of the machine tool. The first driving member is in driving connection with the push plate, and the first driving member is used for driving the push plate to move along the width direction of the machine tool. When the push plate is pushed out, the end of the push plate close to the workpiece extends beyond the ends of the upper clamping plate and the lower clamping plate close to the workpiece.

[0009] By adopting the above technical solution, usually two side clamping and feeding devices for plate members are provided during use, and the two side clamping and feeding devices for plate members are arranged oppositely on both sides of the machine tool. When using the machine tool to process the plate member, the plate member is transported to the workbench through a conveying device. First, the driving assembly drives the base to move to the position of the edge of the plate member along the slide rail of the machine tool, and the upper clamping plate and the lower clamping plate in the clamping plate assembly are opened. Secondly, the push plate assembly in the opposite clamping and feeding device pushes the plate member to the position between the upper clamping plate and the lower clamping plate. Subsequently, the upper clamping plate and the lower clamping plate clamp and fix the plate member at the edge position of the plate member. Finally, after the clamping plate assembly clamps and fixes the plate member, when the driving assembly drives the base to move, the base can also drive the clamping plate assembly to control the plate member to feed along the length direction of the machine tool.

[0010] When the push plate assembly works, the first driving member drives the push plate to push out from the ends of the upper clamping plate and the lower clamping plate. The push plate abuts against the edge position of the plate member to push the plate member to move along the width direction of the machine tool. When the opposite push plate pushes the plate member to the position between the upper clamping plate and the lower clamping plate in the first direction, the push plate in the first direction retracts to the rear of the clamping area, so that the opposite push plate pushes the plate member to the clamping area in the first direction for clamping and fixing. Since the plate member will always be in the position between the upper clamping plate and the lower clamping plate during the clamping and fixing process of the plate member, and when adjusting the height of the upper clamping plate and the lower clamping plate, the height of the plate member is between the upper clamping plate and the lower clamping plate. Therefore, when the push plate is arranged between the upper clamping plate and the lower clamping plate, when using the push plate to push the plate member, only need to adjust the height of the clamping plate assembly to align with the plate member, then the push plate can be adjusted to align with the plate member, without secondary adjustment of the height of the push plate.

[0011] In this way, the push plate assembly is used to push the plate, enabling the position of the plate on the workbench to be flexibly adjusted. The plate can be pushed into the clamping plate assembly by the push plate assembly for clamping and fixing, without the need to place the edge of the plate in advance at a position beyond the edge of the workbench. After the plate is clamped and fixed, it can be pushed back to its original position for reset, facilitating subsequent transportation. At the same time, when the push plate assemblies on both sides of the workbench are extended simultaneously, the plate can also be clamped on the side of the plate, and the extended length of the push plate assembly can be controlled to enable the plate to move along the width direction of the machine tool, further increasing the usage function of the clamping and feeding device of this application.

[0012] Optionally, a telescopic assembly is further provided on the push plate. The telescopic assembly includes a telescopic member and a second driving member. The telescopic member is slidably disposed on the push plate, and the second driving member is fixedly disposed on the push plate for driving the telescopic member to slide along the width direction of the machine tool.

[0013] Since the clamping and feeding device is installed on the side of the workbench, in order to reduce the space occupied by the clamping and feeding device on the side of the workbench and enable the clamping plate assembly to maintain a stable clamping force, the upper clamping plate and the lower clamping plate of the clamping plate assembly are usually set to have a smaller depth. The push plate is installed between the upper clamping plate and the lower clamping plate, and when the push plate is retracted, the end of the push plate is required to be behind the positioning post, resulting in a smaller length of the push plate, so that the push plate cannot extend a long distance and cannot provide effective clamping for plates with a smaller width.

[0014] By adopting the above technical solution, when the push plate extends from the ends of the upper clamping plate and the lower clamping plate, the second driving member will drive the telescopic member to extend from the end of the push plate, and the end of the telescopic member abuts against the plate to push the plate to move or replace the push plate to clamp the side of the plate. When the telescopic member is retracted, the end of the telescopic member close to the workpiece will retract from the end of the push plate, reducing the space occupied by the telescopic machine in the depth direction of the clamping plate assembly. In this way, by setting the telescopic assembly, a two-stage telescopic mechanism can be formed above the push plate, increasing the pushing distance of the push plate in the width direction of the machine tool, and enabling clamping of plates with a smaller width.

[0015] Optionally, both the upper clamping plate and the lower clamping plate are slidably disposed on the base in the vertical direction, and the third driving member is fixedly disposed on the lower clamping plate; an adaptive height adjustment assembly is further provided on the base, and the adaptive height adjustment assembly is used to adjust the height of the lower clamping plate on the base.

[0016] By adopting the above technical solution, since the heights of the workbenches of the machine tools are inconsistent, when using the upper clamping plate and the lower clamping plate to clamp the plate member, it is necessary to move the lower clamping plate below the plate member, move the upper clamping plate above the plate member, and after the upper clamping plate and the lower clamping plate clamp the plate member, make the height of the lower clamping plate flush with the height of the workbench or make the height of the lower clamping plate higher than the workbench to reduce the deformation of the plate member when the clamping plate assembly clamps and fixes the clamping plate. The adaptive height adjustment assembly can automatically adjust the height of the clamping plate assembly to a suitable position, so that the upper clamping plate and the lower clamping plate can stably clamp the plate member; the third driving member is arranged on the lower clamping plate and is used to drive the upper clamping plate to move towards the direction close to the lower clamping plate, so that the third driving member can move together with the lower clamping plate and can control the upper clamping plate and the lower clamping plate to clamp and fix the plate member at any time; arranging the third driving member on the lower clamping plate can also reduce the weight of the upper clamping plate and improve the stability of the upper clamping plate.

[0017] Optionally, the adaptive height adjustment assembly includes a jacking cylinder and a first elastic member; the jacking cylinder is fixedly arranged on the base, and the piston rod of the jacking cylinder abuts against the top of the lower clamping plate and is used to drive the lower clamping plate to move downward; the first elastic member is arranged on the base, the first elastic member is connected with the lower clamping plate, and the first elastic member has a tendency to bounce the lower clamping plate upward.

[0018] By adopting the above technical solution, when the clamping plate assembly clamps the plate member, first, the piston rod of the jacking cylinder extends out and will push the lower clamping plate downward, so that the lower clamping plate is lower than the plate member. Second, the clamping plate assembly moves to the side of the plate member along with the base, so that the lower clamping plate is located below the plate member. Third, the piston rod of the jacking cylinder retracts, and the lower clamping plate moves upward under the action of the first elastic member and abuts against the bottom surface of the plate member. Finally, the upper clamping plate moves downward under the drive of the third driving member, and the plate member is clamped and fixed by the cooperation of the upper clamping plate and the lower clamping plate. Since the plate member has a certain weight, after the upper clamping plate and the lower clamping plate clamp and fix the plate member, the clamping plate assembly will compress the first elastic member under the gravity of the plate member, so that the bottom of the plate member contacts the workbench of the machine tool, and a part of the weight of the plate member is dispersed on the workbench of the machine tool, so that the plate member will not be suspended, and the machining accuracy can be improved during the subsequent machining of the plate member.

[0019] In this way, by the cooperation of the jacking cylinder and the first elastic member, when adjusting the height of the clamping plate assembly, the height of the end surface of the lower clamping plate for supporting the plate member can be automatically made consistent with the height of the workbench of the machine tool. Furthermore, after the plate member is clamped and fixed by the clamping plate assembly, it can still be supported on the workbench, so that the bottom surface of the plate member can be stably supported during the machining process of the plate member, and the machining accuracy of the plate member is improved.

[0020] Optionally, an elastic connection component is also provided between the push plate and the first driving member, and the elastic connection component includes a first folding plate, a second folding plate and an elastic telescopic member; the first driving member is installed under the lower clamping plate, and the first folding plate is fixedly arranged on the movable end of the first driving member; the second folding plate is fixedly connected to the push plate; one end of the elastic telescopic member is connected to the first folding plate, and the other end is connected to the second folding plate, and the elastic telescopic member is arranged along the vertical direction.

[0021] By adopting the above technical solution, the first folding plate and the second folding plate can convert the connection direction between the push plate and the first driving member, so that the first driving member can be installed under the lower clamping plate, and the push plate is installed between the upper clamping plate and the lower clamping plate, thereby reducing the space occupied by the first driving member between the upper clamping plate and the lower clamping plate.

[0022] When the push plate pushes the plate on the machine tool workbench, the height of the push plate needs to be adjusted to be consistent with the height of the workbench. The push plate is installed on the lower clamping plate, and the lower clamping plate can only be adaptively adjusted in height when it abuts against the bottom of the plate. When the lower clamping plate is not in contact with the plate, the height of the push plate cannot be accurately aligned with the height of the workbench. By adopting the above technical solution, when the push plate needs to push the plate on the workbench, the push plate first extends from the end of the lower clamping plate, and then the tightening cylinder pushes the lower clamping plate downward, and the push plate moves downward and abuts against the top of the workbench. When the bottom surface of the push plate abuts against the workbench, the lower clamping plate continues to move downward under the push of the tightening cylinder. At this time, the elastic telescopic member will gradually extend, increasing the distance between the push plate and the lower clamping plate. Finally, the push plate abuts against the workbench and continues to extend, so that the push plate can abut against the side of the plate. In this way, the elastic telescopic part can make the push plate adaptively stick to the pushing workbench when the push plate moves downward, and then the push plate can be aligned with the panel on the workbench. There is no need to accurately adjust the height of the push plate to align the push plate with the panel on the workbench. When the push plate pushes the panel, the push plate can adaptively align with the panel.

[0023] Optionally, a chuck is provided at the end of the upper clamping plate close to the workpiece, and the chuck is used to clamp the upper end surface of the plate.

[0024] When the push plate and the telescopic member push or clamp the panel, the push plate or the telescopic member contacts the panel through the contact surface at the end. In order to increase the stability of the contact between the push plate or the telescopic member and the panel, it is necessary to set a larger thickness at the end of the push plate and the telescopic member to increase the contact area between the push plate and the telescopic member and the side of the panel. Setting a larger thickness for the push plate and the telescopic member will result in a larger distance between the upper clamping plate and the lower clamping plate, which will make it impossible for the upper clamping plate and the lower clamping plate to clamp thinner panels.

[0025] By adopting the above technical solution, a chuck is set at the end of the upper clamping plate, and the chuck protrudes from the bottom of the upper clamping plate, which is used to increase the downward extension distance of the part of the upper clamping plate that clamps the plate, so that when the push plate and the telescopic part occupy the space between the upper clamping plate and the lower clamping plate, the chuck protrudes downward to form a clearance space between the upper clamping plate and the lower clamping plate, and when clamping thinner plates, the plates can be clamped by the chuck and the lower clamping plate.

[0026] Optionally, an air blowing assembly is further provided on the lower clamping plate, and the air blowing assembly includes a blowing block and an air pipe. The blowing block is provided with a plurality of blowing holes, and the plurality of blowing holes are arranged toward the workpiece, and the blowing holes are connected to an external air source through the air pipe.

[0027] When processing plates, the debris generated during the processing is easy to splash. If the debris splashes onto the lower clamp, when the upper and lower clamps clamp the plates, the debris is easy to be pressed between the plates and the lower clamp, causing indentations or scratches on the surface of the plates, affecting the yield rate of the plates. By adopting the above technical solution, before the upper and lower clamps clamp the plates, the external air source will purge the lower clamp through the blowing holes to blow away the debris on the lower clamp, reducing the probability of indentations or scratches on the surface of the plates when the upper and lower clamps clamp the plates, and improving the yield rate of plate processing.

[0028] Optionally, the bottom surface of the push plate is flush with the end surface of the lower clamping plate used to abut the plate member, and a clearance groove is also provided on the lower clamping plate, and the blow block is slidably set in the clearance groove along the vertical direction; a second elastic member is provided inside the clearance groove, and the second elastic member is connected to the blow block, and the second elastic member has the probability of bouncing the blow block upward; a guide assembly is also provided between the blow block and the push plate, and when the push plate is pushed out, the blow block is compressed in the clearance groove through the guide assembly.

[0029] After the plate is clamped and fixed, the upper clamp moves upward to release the clamping of the plate. At this time, the plate is still pressed on the lower clamp. In order to enable the push plate to push the thinner plate, the bottom surface of the push plate is flush with the end surface of the lower clamp used to abut the plate, so that the push plate pushes the bottom side of the plate. When the air blowing assembly is working, it needs to be aimed at the lower clamping plate to blow, causing the push plate to interfere with the air blowing assembly when it is pushed out.

[0030] By adopting the above technical solution, when the push plate is pushed out, the push plate cooperates with the guide assembly to compress the blowing block into the clearance groove. When the push plate is retracted, the push plate moves upward under the action of the second elastic member and extends out of the clearance groove. In this way, by setting the clearance groove below the blowing block and setting the guide assembly between the blowing block and the push plate, the blowing block moves downward into the clearance groove when the push plate is pushed out, reducing the risk of interference between the blowing block and the push plate; when the push plate is retracted, the blowing block moves upward under the action of the second elastic member and rises from the clearance groove, and can continue to blow the lower clamping plate.

[0031] Optionally, the guide assembly is a guide block, and a guide groove is also provided on the lower clamping plate. The guide block is slidably arranged in the guide groove along the vertical direction, and the guide block is fixedly connected to the blowing block; a guide surface is provided on the top of the guide block, and the guide surface is used to cooperate with the end of the push plate in contact with the plate member. When the push plate is pushed out, the guide block moves downward under the cooperation of the guide surface and the push plate.

[0032] By adopting the above technical solution, when the push plate is pushed out, the end of the push plate in contact with the plate member abuts against the guide surface, and the guide surface is inclined so that the pressure of the push plate on the guide surface is converted into a downward force to move the guide block downward. The guide block is fixedly connected to the blowing block, so that the guide block drives the blowing block to move downward and compresses the second elastic member, and the blowing block is stored in the clearance groove; when the push plate is retracted, the push plate removes the pressure on the guide surface, and the blowing block moves upward under the elastic action of the second elastic member, and finally the blowing block extends out of the clearance groove and blows the lower clamping plate. The setting of the guide surface can compress the second elastic member when the push plate moves, so that the blowing block is stored in the clearance groove, realizing the linkage effect of the push plate being pushed out and the blowing block moving downward, and reducing the probability of collision between the blowing block and the push plate.

[0033] Optionally, the lower clamping plate is further provided with a positioning column, the positioning column is used to abut against the plate to limit the clamping length of the upper clamping plate and the lower clamping plate on the plate, and the upper clamping plate is further provided with a positioning groove, the positioning groove is used to accommodate the positioning column;

[0034] An optical axis is arranged on the upper clamping plate, and a shaft sleeve is arranged on the lower clamping plate. The optical axis is arranged vertically, and the optical axis passes through the shaft sleeve.

[0035] By adopting the above technical solution, when the push plate assembly pushes the plate member and the plate member moves to the clamping area of the clamping plate assembly, the end of the plate member will abut against the positioning post, and the push plate assembly will retract behind the positioning post. Also, the air blowing block is arranged behind the positioning post, and the clamping area of the clamping plate assembly is limited between the positioning post and the end of the lower clamping plate, so as to reduce the probability of interference between the plate member and the push plate or the air blowing block, playing a protective role. At the same time, setting multiple positioning posts can abut against multiple positions at the end of the plate member when abutting against the plate member, reducing the probability of the plate member skewing after being pushed to the clamping area of the clamping plate assembly, increasing the stability of the plate member, and further increasing the processing accuracy of the plate member.

[0036] By adopting the above technical solution, during the process of the upper clamping plate moving up and down relative to the lower clamping plate driven by the third driving member, the optical axis slides through the bushing, thus playing a role of sliding limit, being able to reduce the offset of the position of the upper clamping plate relative to the lower clamping plate during the moving process, and improving the stability when the upper clamping plate and the lower clamping plate clamp the plate member.

[0037] In summary, the present invention includes at least one of the following beneficial technical effects:

[0038] By arranging a push plate assembly on the clamping and feeding device, when the clamping and feeding device clamps the plate member at the edge position of the plate member, the push plate assembly can push the plate member from the side of the plate member, pushing the plate member into the clamping range of the clamping assembly, without the need to place the edge of the plate member in a position beyond the edge of the workbench in advance, reducing the probability of collision during the conveying process of the plate member. At the same time, when the push plate assembly extends, it can also clamp the plate member from the side of the plate member and control the movement of the plate member along the width direction of the machine tool, enabling the clamping and feeding device to simultaneously control the feeding actions of the plate member in two directions.

[0039] An expansion and contraction assembly is arranged on the push plate of the pushing assembly. The expansion and contraction assembly can extend and retract on the push plate. When the expansion and contraction assembly extends, the expansion and contraction assembly can replace the push plate and abut against the side of the plate member, increasing the pushing distance of the plate member. When the expansion and contraction assembly retracts, the distance occupied by the expansion and contraction assembly in the length direction of the push plate can be reduced.

[0040] The clamping plate assembly is arranged on the adaptive height adjustment assembly. When the clamping plate assembly clamps the plate member, there is no need to precisely adjust the height of the clamping plate assembly corresponding to the plate member. It only needs to adjust the lower clamping plate below the plate member and the upper clamping plate above the plate member. When clamping the plate member, under the adjustment of the adaptive height adjustment assembly, the upper clamping plate and the lower clamping plate can automatically adjust their heights to clamp the plate member and support the plate member on the workbench. Thus, when processing the plate member, the lower part of the plate member can be effectively supported, improving the accuracy during the processing of the plate member.

[0041] An air blowing assembly is arranged on the lower clamping plate to blow away the debris on the lower clamping plate, thereby reducing the probability of the debris being pressed against the surface of the plate when the clamping plate assembly clamps the plate, thereby improving the yield rate of the plate. At the same time, a yield groove and a second elastic member are arranged below the air blowing assembly, so that when the push plate is pushed out, the push plate can press the air blowing assembly in the yield groove through the guide assembly, thereby reducing the probability of interference between the push plate and the air blowing assembly during movement.

DETAILED DESCRIPTION

[0050] For a device that needs to contact the upper and lower end faces of a plate member and clamp the plate member, when the clamping and feeding device clamps and fixes the plate member, the edge position of the plate member needs to be suspended, leaving a position for contact and fixation with the clamping and feeding device at the edge of the plate member. This results in the need to place the edge of the plate member beyond the edge of the workbench during plate processing, suspending the edge of the plate member. In the process of pipeline production, placing the edge of the plate member beyond the edge of the conveying device means an increased risk of collision and interference between the edge of the plate member and other structures.

[0051] To solve the above problems, an additional pushing mechanism is provided opposite to the clamping and feeding device. So that when the plate member is clamped and fixed, the plate member can be pushed to the clamping area of the clamping and feeding device opposite to the clamping and feeding device, and after clamping, another pushing mechanism is used to push the plate member back to its original position to reset the plate member; considering that the clamping and feeding device can drive the plate member to move, resulting in a change in the position of the clamping and feeding device, so in this application, the pushing mechanism and the clamping and feeding device are fixedly arranged together to control the plate member to move along the width direction of the machine tool to achieve clamping.

[0052] The following combines Figures 1 to 7 to further elaborate on the present invention in detail.

[0053] An embodiment of the present invention discloses a side clamping and feeding device for a plate member. Refer to Figures 1 to 3 , a side clamping and feeding device for a plate member mainly includes a base 100, a driving component 110, a clamping plate component 200, and a pushing plate component 300. Among them, the driving component 110 is arranged at one end of the base 100. The base 100 is slidably installed on the guide rail of the machine tool through the driving component 110. The driving component 110 can drive the clamping plate to slide along the length direction of the machine tool. The clamping plate component 200 is installed on the side of the base 100 close to the workpiece. After the base 100 moves to the corresponding position of the workpiece, the clamping plate component 200 can clamp at the edge position of the plate member. The pushing plate component 300 is arranged between the clamping plate components 200. When the plate member is on the machine tool, the pushing plate component 300 can push the plate member to move along the width direction of the machine tool, and then push the plate member into the clamping range of the clamping plate component 200.

The lower end of the first elastic member 430 is fixedly arranged on the base 100, and the upper end of the first elastic member 430 abuts against the bottom of the vertical plate of the lower clamping plate 220. The cylinder body of the top pressing cylinder 420 is fixedly arranged on the top plate 410. The piston rod of the top pressing cylinder 420 faces downward, and the end of the piston rod of the top pressing cylinder 420 abuts against the top of the vertical plate of the lower clamping plate 220.

[0058] When the adaptive height adjustment component 400 works, first, the piston rod of the jacking cylinder 420 extends to push the lower clamping plate 220 below the plate member. Secondly, the clamping plate assembly 200 moves to the clamping position. Thirdly, the jacking cylinder 420 contracts, and the lower clamping plate 220 moves upward under the action of the first elastic member 430. Since the plate member has weight, the lower clamping plate 220 will abut against the bottom surface of the plate member during the upward movement, thereby positioning the height of the lower clamping plate 220. Finally, the upper clamping plate 210 moves close to the lower clamping plate 220 under the drive of the third driving member 230 to clamp the plate member, realizing the adaptive adjustment of the height of the clamping plate assembly 200.

[0059] Referring to Figure 3 , a light shaft 212 is also fixedly arranged on the upper clamping plate 210. The light shaft 212 is arranged in the vertical direction. A bushing 224 is also fixedly arranged on the lower clamping plate 220. The light shaft 212 is inserted into the bushing 224, and the outer peripheral surface of the light shaft 212 is in sliding contact with the inner ring surface of the bushing 224. In this embodiment, the bushing 224 is a graphite bushing 224. When the upper clamping plate 210 slides relative to the lower clamping plate 220 in the vertical direction, the light shaft 212 slides in the bushing 224 in the vertical direction to guide the sliding of the upper clamping plate 210 and increase the sliding stability of the upper clamping plate 210.

[0060] Referring to Figure 4 , the push plate assembly 300 includes a first driving member 310, a push plate 320 and a positioning post 330. In order to reduce the occupation of the space between the upper clamping plate 210 and the lower clamping plate 220, the first driving member 310 is fixedly arranged below the lower clamping plate 220. In this embodiment, the first driving member 310 is a cylinder. The cylinder body of the first driving member 310 is fixedly arranged below the lower clamping plate 220.

The push plate 320 is slidably arranged between the upper clamping plate 210 and the lower clamping plate 220 along the width direction of the machine tool. The positioning post 330 is fixedly arranged on the end face of the lower clamping plate 220 facing the upper clamping plate 210. The positioning post 330 is fixedly arranged at the end of the lower clamping plate 220 close to the workpiece. When the upper clamping plate 210 and the lower clamping plate 220 perform clamping, the side of the plate member abuts against the positioning post 330 for limiting.

[0061] Referring to Figure 5 and Figure 6, an elastic connection assembly 500 is further provided between the push plate 320 and the first driving member 310. The elastic connection member includes a first folding plate 510, a second folding plate 520, and an elastic telescopic member 530. One end of the first folding plate 510 is fixedly arranged at the end of the piston rod of the first driving member 310, and the other end of the first folding plate 510 extends out from the side of the lower clamping plate 220 through the bending part. One end of the elastic telescopic member 530 is fixedly arranged at the end of the first folding plate 510 far from the first driving member 310. One end of the second folding plate 520 is fixedly arranged at the other end of the elastic telescopic member 530. The other end of the second folding plate 520 extends between the upper clamping plate 210 and the lower clamping plate 220 through bending, and the end of the second folding plate 520 far from the elastic telescopic member 530 is arranged in the horizontal direction. The push plate 320 is fixedly arranged at the horizontally arranged end of the second folding plate 520. In this embodiment, the elastic telescopic member 530 adopts a gas spring.

[0062] When the push plate 320 pushes the plate on the workbench of the machine tool, first, the push plate 320 extends along the width direction of the machine tool. Secondly, the base 100 controls the push plate 320 to move to a position corresponding to the plate. Thirdly, the jacking cylinder 420 in the adaptive height adjustment assembly 400 pushes the lower clamping plate 220 downward. The push plate 320 moves downward along with the lower clamping plate 220. During the process of the push plate 320 moving downward, the bottom surface of the push plate 320 abuts against the upper surface of the workbench of the machine tool. During the process of the push plate 320 continuing to move downward along with the lower clamping plate 220, the elastic telescopic member 530 will be stretched, so that the push plate 320 is pressed against the surface of the workbench of the machine tool to push the plate to move, enabling the push plate 320 not to need to be accurately aligned with the workbench when moving downward, and realizing the adaptive adjustment of the height of the push plate assembly 300.

[0063] Refer to Figure 6 , in order to increase the pushing distance of the push plate 320 along the width direction of the machine tool and enable the push plate assembly 300 to push the relatively narrow plate on the machine tool, a telescopic assembly 600 is further installed on the push plate 320. The telescopic assembly 600 includes a telescopic member 610 and a second driving member 620. Specifically, a square groove is arranged on the push plate 320 along the width direction of the machine tool. The size of the telescopic member 610 corresponds to the size of the square groove. The telescopic member 610 is slidably arranged in the square groove. An installation hole is arranged at the center of the telescopic member 610. The second driving member 620 adopts a cylinder. The cylinder body of the second driving member 620 is fixedly installed in the square groove. The piston rod of the second driving member 620 passes through the installation hole of the telescopic member 610 and is fixedly arranged with the telescopic member 610. The second driving member 620 is arranged along the length direction of the square groove, so that when the second driving member 620 extends, it can push the telescopic member 610 out of the square groove, realizing the extension of the telescopic member 610. In order to increase the contact area between the telescopic member 610 and the plate and increase the stability when the telescopic member 610 pushes the plate, a contact block is further fixedly arranged at the end of the telescopic member 610 close to the plate.

[0064] Reference Figure 4 and Figure 7 In order to reduce the debris generated during the processing of the plate and falling on the lower clamping plate 220, an air blowing assembly 700 is also fixedly arranged on the lower clamping plate 220. The air blowing assembly 700 includes a blowing block 710 and a guide assembly 800. A clearance groove 222 is arranged at one end of the lower clamping plate 220 close to the clamping area, and a second elastic member 223 is arranged in the clearance groove 222. In this embodiment, the second elastic member 223 adopts a spring, and one end of the second elastic member 223 is fixedly arranged at the bottom of the clearance groove 222. The bottom of the blowing block 710 is fixedly arranged at the other end of the second elastic member 223. A blowing hole 711 is arranged on the end face of the blowing block 710 facing the plate, and the blowing hole 711 is connected to an external air source through an air pipe.

[0065] Reference Figure 4 and Figure 7 In order to enable the blowing block 710 to be automatically stored in the clearance groove 222 when the push plate 320 is pushed out, the blowing block 710 is linked with the push plate 320 through the guide assembly 800. The specific guide assembly 800 is a guide block 810. The lower clamping plate 220 is also provided with a guide groove 820. The guide groove 820 is arranged on the side of the clearance groove 222 away from the plate. The guide block 810 is slidably arranged in the guide groove 820 along the vertical direction. The guide block 810 is fixedly connected with the blowing block 710. Next, a guide surface 811 is provided on the top of the guide block 810, and the guide surface 811 is provided at one end of the guide block 810 facing the push plate 320. In order to increase the stability of the contact between the push plate 320 or the telescopic member 610 and the panel, a larger thickness is provided at the end of the push plate 320 and the telescopic member 610 facing the panel, and the bottom of the push plate 320 is in sliding contact with the upper end surface of the lower clamping plate 220, and the end of the push plate 320 or the telescopic member 610 facing the panel is pressed on the guide surface 811 of the guide block 810.

[0066] When the push plate 320 and the telescopic member 610 are extended, the ends of the push plate 320 and the telescopic member 610 are pressed on the guide surface 811, and the guide surface 811 is inclined, so that the pressure of the push plate 320 on the guide surface 811 is converted into a downward force to move the guide block 810 downward, and the guide block 810 is fixedly connected to the blowing block 710, so that the guide block 810 will drive the blowing block 710 to move downward, and compress the second elastic member 223, and the blowing block 710 is stored in the clearance groove 222; when the push plate 320 is retracted, the push plate 320 removes the pressure on the guide surface 811, and the blowing block 710 moves upward under the elastic action of the second elastic member 223, and finally the blowing block 710 extends out of the clearance groove 222 and blows toward the lower clamping plate 220.

[0067] In this embodiment, when the push plate 320 and the telescopic member 610 occupy the space between the upper clamp plate 210 and the lower clamp plate 220, a clamp 211 is provided at the end of the upper clamp plate 210 close to the plate, and the clamp 211 protrudes downward from the bottom surface of the upper clamp plate 210, forming a clearance space between the upper clamp plate 210 and the lower clamp plate 220, and when clamping a thinner plate, the plate can be clamped by the clamp 211 and the lower clamp plate 220.

[0068] The implementation principle of a side clamping and feeding device for a plate in an embodiment of the present invention is as follows: at least two clamping and feeding devices are provided in the present application, and the two clamping and feeding devices are arranged on both sides of the machine tool relatively. When the first clamping and feeding device clamps the plate, the push plate 320 or the telescopic member 610 in the second clamping and feeding device extends to push the plate to the clamping area of ​​the first clamping and feeding device. When it is necessary to control the plate to move along the width direction of the machine tool, the push plates 320 or the telescopic member 610 in the first clamping and feeding device and the second clamping and feeding device extend. The parts 610 extend out at the same time, clamp on both sides of the plate, and control the extension distance of the push plate 320 and the telescopic part 610, and control the lateral movement distance of the plate; when the clamping plate assembly 200 clamps the plate, the clamping plate assembly 200 adjusts the height of the clamping plate assembly 200 through the adaptive height adjustment assembly 400, so that the height of the clamping plate assembly 200 corresponds to the height of the workbench of the machine tool; when the push plate 320 pushes the plate, the push plate 320 is pressed into the workbench surface of the machine tool under the control of the elastic telescopic assembly 600 to push the plate.

[0069] In summary, the present application sets a push plate assembly 300 on the clamping and feeding device. The push plate assembly 300 can push the plate at the side of the plate and push the plate into the clamping range of the clamping assembly. There is no need to place the edge of the plate beyond the edge of the workbench in advance, thereby reducing the probability of collision during the plate transportation process. At the same time, when the push plate assembly 300 is extended, it can also clamp the plate at the side of the plate and push the plate to move along the width direction of the machine tool, so that the clamping and feeding device can simultaneously control the feeding action of the plate in two directions. At the same time, the clamping plate assembly 200 is set at an adaptive high On the height adjustment component 400, when the clamping plate assembly 200 clamps the panel, there is no need to accurately adjust the height of the clamping plate assembly 200 to correspond to the panel. It is only necessary to adjust the lower clamping plate 220 to the bottom of the panel and adjust the upper clamping plate 210 to the top of the panel. When clamping the panel, the upper clamping plate 210 and the lower clamping plate 220 can adjust the height of the upper clamping plate 210 and the lower clamping plate 220 by themselves under the adjustment of the adaptive height adjustment component 400 to clamp the panel and support the panel on the workbench, so that the bottom of the panel can be effectively supported during processing, thereby improving the accuracy of panel processing.

[0070] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
