Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamping fixtures, in particular to a pneumatic clamping fixture for mold processing. Background Art
[0002] Pneumatic clamps are mainly composed of gas-liquid booster cylinders, clamp bodies and positioning devices. Compressed air is converted into strong pressure through the gas-liquid booster cylinder to push the clamp body to move, so that the clamp body and positioning device generate clamping force and positioning force, thereby achieving the clamping and positioning of the workpiece.
[0003] Using a cylinder to drive the fixture to move has the advantages of fast speed, large torque, simple structure and easy control. However, the operation of the cylinder requires the piston inside it to move continuously. In order to reduce the friction coefficient and wear degree of the piston during movement, the piston needs to be lubricated. The more common lubrication method is to disassemble the cylinder and add lubricating oil, and then assemble it after adding. Since the lubricating oil is consumed quickly, this operation is often required. This method of frequently disassembling and adding lubricating oil to the cylinder itself is also a kind of wear and tear on the cylinder.
[0004] Therefore, we made improvements to this and proposed a pneumatic clamping fixture for mold processing. Utility Model Content

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0022] Example: Figures 1 to 4 As shown, the utility model is a pneumatic clamping fixture for mold processing, including a clamping plate 4, the clamping plate 4 is arranged at the end of a cylinder 5, the cylinder 5 is arranged on a processing table 1, a mold body 3 is also placed on the processing table 1, an L-shaped plate 2 is fixedly arranged on one side of the processing table 1, and a drill 6 for drilling holes in the mold body 3 is arranged at the bottom of the horizontal section of the L-shaped plate 2; a placement groove (not shown in the figure) for placing the mold body 3 is also opened on the processing table 1, and an existing control switch (not shown in the figure) for controlling the start and stop of the cylinder 5 can also be arranged on the processing table 1, the mold body 3 is placed in the placement groove, and the clamping plate 4 is driven to move by the cylinder 5, so that the clamping plate 4 can be attached to the surface of the mold body 3, the clamping plate 4 is in a U-shaped structure, and the square structure of the mold body 3 can be limited by the clamping plate 4 and the vertical section of the L-shaped plate 2, so as to facilitate the drilling operation by the drill 6.
[0023] A U-shaped frame 9 is also provided on the processing table 1. Connecting plates 13 are symmetrically provided on opposite surfaces of the inner wall of the U-shaped frame 9. A sponge block 10 is fixedly connected to the bottom end of the connecting plate 13. One end of the sponge block 10 is arranged in the box body 11. A bidirectional threaded rod 14 is threadedly provided between the connecting plates 13. One end of the bidirectional threaded rod 14 passes through the outside of the U-shaped frame 9 and is fixedly provided with a rotating disk 15. A rotating rod 16 is fixedly provided on the rotating disk 15.
[0024] When the rotating rod 16 is rotated, the rotating disk 15 can be driven to rotate, thereby driving the bidirectional threaded rod 14 to rotate. When the bidirectional threaded rod 14 rotates, the two connecting plates 13 respectively drive the two sponge blocks 10 to move in a direction close to each other until they are attached to the surface of the telescopic end of the cylinder 5. When the telescopic end of the cylinder 5 is extended and retracted, it rubs against the sponge block 10, so that the lubricating oil adsorbed on the sponge block 10 can be wiped on the surface of the telescopic end of the cylinder 5, thereby lubricating it. This method of adding lubricating oil for lubrication does not require the cylinder 5 to be disassembled, which can reduce damage to the cylinder 5.
[0025] The top of the connecting plate 13 is slidably connected to the inner top surface of the U-shaped frame 9; the opposite surface of the sponge block 10 is arc-shaped, and the two sponge blocks 10 are located on both sides of the telescopic part of the cylinder 5. The arc-shaped structure makes it easy for the sponge block 10 to fit on the surface of the telescopic end of the cylinder 5 and wrap the telescopic end of the cylinder 5 through the two arc-shaped structures.
[0026] A through slot 17 is provided through the U-shaped frame 9, and the through slot 17 is opposite to the box body 11, and the size of the through slot 17 is larger than the size of the box body 11. The side of the sponge block 10 away from the cylinder 5 can be detachably installed in the box body 11, and a refueling port 12 for adding lubricating oil is provided at the top of the box body 11, and the refueling port 12 is located at the top of the sponge block 10. Lubricating oil is added to the sponge block 10 in the box body 11 through the refueling port 12, so that the sponge block 10 absorbs the lubricating oil, thereby lubricating the cylinder 5. When the sponge block 10 moves, the bottom end of the connecting plate 13 is fixedly connected to the top of the box body 11, so that when the connecting plate 13 moves, the box body 11 can be driven to move, thereby moving the sponge block 10.
[0027] A fixing plate 7 is fixedly arranged on one side of the top of the processing table 1, and the fixing plate 7 is connected to the fixed end of the cylinder 5. A support plate 8 is also installed on the top surface of the processing table 1, and the top of the support plate 8 is arranged in an arc shape, and the support plate 8 is arranged on the bottom surface of the fixed end of the cylinder 5 to support the cylinder 5. The cylinder 5 can be fixed and supported by the fixing plate 7 and the support plate 8, thereby enhancing the stability of the fixed end of the cylinder 5.
[0028] The top of the processing table 1 is symmetrically provided with a slide groove, and the U-shaped frame 9 is arranged between the two slide grooves, and the slide groove is slidably connected with the bottom end of the clamping plate 4. When the clamping plate 4 moves, its bottom end will slide along the slide groove, thereby playing a guiding role.
[0029] During operation, the mold body 3 is placed in the placement groove, and the cylinder 5 is started. The cylinder 5 drives the clamping plate 4 to move along the slide groove toward the mold body 3, and limits the module body 3. When the module body 3 is limited, it can be drilled; when it is necessary to lubricate the telescopic end of the cylinder 5, the rotating rod 16 can be rotated to drive the rotating disk 15 to rotate, and the rotating disk 15 drives the bidirectional threaded rod 14 to rotate. The rotation of the bidirectional threaded rod 14 can make the two sponge blocks 10 approach each other and fit on the surface of the telescopic end of the cylinder 5. When the telescopic end of the cylinder 5 is extended and retracted, the lubricating oil on the surface of the sponge block 10 can be wiped on the surface of the telescopic end of the cylinder 5, thereby playing a lubricating role. This method does not require the cylinder 5 to be disassembled to complete the lubrication of the telescopic end of the cylinder 5. The operation is simple and reduces damage to the cylinder 5.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
