This utility model is provided with a moving component, a lifting component, and a clamping component, which can move the clamping component to a position to be clamped to clamp the workpiece body, and move the workpiece body to a specified position, thereby replacing manual handling and improving work efficiency.

[0004] The above-mentioned mechanism transfers the position of the workpiece through the lifting component and the clamping component. However, in actual use, the transfer efficiency of a single clamping component is low. During the transfer process, the workpiece to be clamped on the other side needs to stay or slow down the conveying speed to wait for the clamp to clamp it, affecting the overall work efficiency. Utility Model Content

[0005] The purpose of the present utility model is to provide a grinding and picking fixture with an impurity cleaning function, so as to solve the problem in the above background technology that the efficiency of a single clamping component is low, which affects the overall subsequent processing efficiency.

[0006] To achieve the above-mentioned object, the utility model provides the following technical solution: a grinding and removing fixture with an impurity cleaning function, comprising a mounting plate and a drive motor mounted on the mounting plate via a coupling, wherein the output end of the drive motor is connected to the top end of the mounting plate, both ends of the top end of the mounting plate are fixedly connected to a pneumatic telescopic rod, and the output end of the pneumatic telescopic rod is fixedly connected to a fixing plate, both ends of the fixing plate are hinged to a connecting rod via a hinged rod, and the outer side of the connecting rod is connected to a clamping plate via a limit frame;

[0007] A limit plate is provided below the fixed plate, and the limit plate is rotatably connected to the connecting rod. An impurity cleaning mechanism for cleaning the surface of the workpiece is provided inside the limit plate, and the impurity cleaning mechanism includes a high-pressure nozzle, and the high-pressure nozzle is engaged and connected to the inside of the limit plate;

[0008] The inner side of the connecting rod is slidably connected with a pushing plate, and a pushing mechanism is provided above the pushing plate. The pushing mechanism is used to push out a workpiece that is stuck during clamping.

[0009] Furthermore, one side of the high-pressure nozzle passes through the limiting plate and extends to the bottom of the limiting plate, and the high-pressure nozzle is symmetrically distributed about the axis in the vertical direction of the mounting plate.

[0010] Furthermore, the extending mechanism includes a return spring, and the top end of the return spring is connected to the top end of the limiting plate, and the bottom end of the return spring is connected to the top end of the extending plate.

[0011] Furthermore, the bottom end of the limiting plate and the top end of the extending plate are both fixedly connected with conductive sheets, and a displacement sensor is provided at a fixed distance in the middle of the bottom end of the extending plate.

[0012] Furthermore, an anti-slip pad is fixedly connected to the inner side of the clamping plate, and the area of ​​the anti-slip pad is smaller than the area of ​​the upper end of the clamping plate.

[0013] Furthermore, both ends of one side of the outer portion of the limiting frame are engaged with a clamping block, and one side of the connecting rod is provided with a plurality of clamping slots matching the clamping blocks.

[0014] Furthermore, both ends of the clamping block are fixedly connected with connecting springs, and the connecting springs and the limiting frame are welded into an integrated structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. During the clamping process, since the surface of the workpiece will retain debris and dirt generated during processing, when the clamping mechanism is used to transfer the workpiece on the conveyor belt, the high-pressure nozzle inside the limit plate can spray high-pressure air to clean the surface of the workpiece, thereby effectively reducing the dirt on the workpiece surface and avoiding problems such as rust on the workpiece surface caused by dirt, ensuring the cleanliness of the workpiece and also ensuring the overall production and processing quality of the workpiece;

[0017] Furthermore, the mounting plate can be controlled to rotate by the driving motor, so that the two pneumatic telescopic rods can continuously rotate left and right and alternate positions according to different needs, thereby better ensuring work efficiency and avoiding the need for the conveyor belt of the workpiece to reduce the conveying speed to wait for the clamping mechanism to clamp during the processing process, thus reducing time waste and increasing overall work efficiency.

[0018] Furthermore, the output end of the pneumatic telescopic rod moves downward, so that the fixed plate is pushed, and at the same time the angle of the hinged rod changes. The angle of the connecting rod is simultaneously limited by the hinged rod and the limit plate, so that the connecting rod rotates inward when the output end of the pneumatic telescopic rod moves downward, thereby clamping the workpiece and completing the overall clamping process. During the clamping process, the anti-slip pad can increase the anti-slip performance between the workpiece and the clamping plate, effectively preventing the workpiece from slipping during the clamping process.

[0019] 2. After the workpiece is clamped and unloaded, the pneumatic telescopic rod controls the length of the output end while the elastic force of the return spring pushes the extension plate out, preventing the workpiece from being stuck on one side between the clamping plates. This prevents the workpiece from being unable to escape from the fixture during transfer, ensuring work efficiency and reducing the need to manually adjust the workpiece position.

[0020] Furthermore, when the clamping plate is worn, the block is moved to one side to separate the block from the slot, thereby removing the position restriction of the limit frame and allowing the limit frame to slide up and down on the outside of the connecting rod, thereby realizing the disassembly and replacement of the limit frame and the clamping plate. In addition, different clamping plates can be installed according to different needs by using multiple different slots, thereby ensuring that the clamping plate can be more stable when clamping the workpiece, avoiding problems such as clamping slippage caused by wear.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] like Figures 1-4 The technical solution shown is to solve the problem that when clamping a workpiece, the clamping efficiency of a single clamping component is low, and at the same time, debris and dirt caused by processing will remain on the surface of the workpiece, affecting subsequent processing: the grinding and picking fixture with impurity cleaning function discloses an impurity cleaning mechanism, including a mounting plate 2 and a driving motor 1 installed on the mounting plate 2 through a coupling, the output end of the driving motor 1 is connected to the top of the mounting plate 2, both ends of the top of the mounting plate 2 are fixedly connected to a pneumatic telescopic rod 3, and the output end of the pneumatic telescopic rod 3 is fixedly connected to a fixed plate 4, both ends of the fixed plate 4 are hinged to a connecting rod 7 through a hinged rod 5, and the outer side of the connecting rod 7 is connected to a clamping plate 8 through a limit frame 11. 4 is provided below a limit plate 6, and the limit plate 6 and the connecting rod 7 are rotatably connected. An impurity cleaning mechanism for cleaning the surface of the workpiece is provided inside the limit plate 6, and the impurity cleaning mechanism includes a high-pressure nozzle 9, and the high-pressure nozzle 9 is snap-connected to the inside of the limit plate 6, the inner side of the connecting rod 7 is slidably connected to a top extension plate 12, and a top extension mechanism is provided above the top extension plate 12, and the top extension mechanism is used to push out the workpiece stuck during clamping, one side of the high-pressure nozzle 9 passes through the limit plate 6 and extends to the bottom of the limit plate 6, and the high-pressure nozzle 9 is symmetrically distributed about the axis of the vertical direction of the mounting plate 2, and an anti-slip pad 10 is fixedly connected to the inner side of the clamping plate 8, and the area of ​​the anti-slip pad 10 is smaller than the upper end area of ​​the clamping plate 8.

[0032] In this example, during the clamping process, since the surface of the workpiece will have debris and dirt generated during processing, when the conveyor belt is transferred stably by clamping, the surface of the workpiece can be cleaned by spraying high-pressure air through the high-pressure nozzle 9 inside the limit plate 6, thereby effectively reducing the dirt on the surface of the workpiece, avoiding problems such as rust on the surface of the workpiece caused by dirt, ensuring the cleanliness of the workpiece, and also ensuring the overall quality of the workpiece. By installing the drive motor 1 on the conveyor belt where the workpiece needs to be transported and transferred, the production line for processing the workpiece is transferred, and the drive motor 1 can control the mounting plate 2 to rotate, so that the two pneumatic telescopic rods 3 can continuously rotate left and right and alternate positions according to different needs, so as to better The workpiece is then clamped in place by the guide rails 5 and the guide rails 6, which are in contact with the workpiece and are then clamped. The workpiece is then clamped in place by the guide rails 5 and the guide rails 6. The workpiece is then clamped in place by the guide rails 5 and the guide rails 6.

[0033] Example 2:

[0034] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The technical solution shown is to solve the problem that the workpiece cannot be separated from the clamp due to the jamming between the workpiece and the clamp when the workpiece is clamped: the grinding and removing clamp with impurity cleaning function discloses a lifting mechanism, which includes a reset spring 13, and the top of the reset spring 13 is connected to the top of the limit plate 6, and the bottom end of the reset spring 13 is connected to the top of the lifting plate 12. The bottom end of the limit plate 6 and the top end of the lifting plate 12 are fixedly connected with a conductive sheet 14, and a displacement sensor 15 is provided at a fixed distance in the middle position of the bottom end of the lifting plate 12.

[0035] When the workpiece is clamped, the workpiece will exert pressure on the top plate 12 below the limit plate 6, and the workpiece will squeeze the distance between the top plate 12 and the limit plate 6, so that the two conductive plates 14 will come into contact, thereby realizing conductivity and further realizing signal transmission. When the two conductive plates 14 are squeezed and contacted, the signal that the workpiece is stably clamped is transmitted, and subsequent position transfer is performed. When the clamping position is offset, the contact between the conductive plates 14 will be unstable, and the signal transmission of the unclamped state will be performed. At the same time, the displacement sensor 15 can realize the signal transmission of its own position change, and track the signal transmission of the workpiece during clamping in real time. After the workpiece is clamped, when unloading, the pneumatic telescopic rod 3 is used to control the output end length, and the elastic force of the reset spring 13 is used to push the top plate 12 out, so that the workpiece cannot be clamped on one side between the clamping plates 8, thereby avoiding the situation where the workpiece cannot be separated from the clamp during the transfer process, ensuring the work efficiency during processing, and reducing the need to manually adjust the workpiece position.

[0036] Example 3:

[0037] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 The technical solution shown in Figure 7 is to solve the problem that it is inconvenient to replace the fixture when it is worn after being used for a period of time: the grinding and removal fixture with impurity cleaning function discloses a limiting mechanism, and both ends of the outer side of the limiting frame 11 are engaged with a clamping block 16, and one side of the connecting rod 7 is provided with multiple clamping grooves 18 matching the clamping block 16, and both ends of the clamping block 16 are fixedly connected with a connecting spring 17, and the connecting spring 17 and the limiting frame 11 are welded into an integrated structure.

[0038] In this example, when the clamping plate 8 is worn, the block 16 is moved to one side to separate the block 16 from the slot 18, thereby removing the position restriction of the limit frame 11 and allowing the limit frame 11 to slide up and down on the outside of the connecting rod 7, thereby realizing the disassembly and replacement of the limit frame 11 and the clamping plate 8, and using multiple different slots 18 to install different clamping plates 8 according to different needs, thereby ensuring that the clamping plate 8 can be more stable when clamping the workpiece, avoiding problems such as clamping slippage caused by wear.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
