Technical Field
[0001] The utility model relates to the field of tooling fixtures, in particular to a fixture tooling for processing filter plates. Background Art
[0002] The extruder filter plate is a porous plate part, which is formed by punching holes on the plate during processing. The punching methods include drilling, laser cutting, water jet cutting, etc. No matter which punching method is used, the plate needs to be positioned and fixed on the workbench of the punching equipment; such as the invention patent with application number: CN201410669090.3, which discloses a plate punching fixture, which is positioned by a special template, and then the pressure block and the slider are pushed by bolts to perform horizontal limit and vertical compression to achieve the positioning and fixation of the plate; this fixture relies on the template for positioning, belongs to a special mold, and requires manual alignment, and the plate is fixed by the lower support and no upper compression. This fixing method is the most common, but because there is a support block at the bottom of the plate, it will affect the falling of the material when drilling, so when fixing, it is necessary to deliberately make the bottom support block avoid the drilling position. For filter plates with denser filter holes, it is difficult to avoid all drilling positions. Summary of the invention
[0003] The utility model provides a clamp tooling for processing a filter plate, aiming to solve the problem that the filter plate punching clamp needs to be manually positioned and needs to avoid a supporting position.
[0004] The technical solution includes a base plate, on which four groups of clamping units are evenly distributed on a horizontal circumference. Each group of clamping units includes a screw rod, which is arranged radially along the distribution circle of the clamping units. The screw rod is rotatably mounted on the base plate. A moving block is mounted on the screw rod, and the moving block cooperates with the screw thread. A vertical clamping roller is fixed to the upper end of the moving block. When the screw rod rotates, the moving block and the clamping roller can be driven to move along the screw rod. A plurality of support rods of equal height are arranged on the base plate.
[0005] The inner ends of two colinear screws are fixedly connected to form a long rod, on which a first bevel gear is installed, and the inner ends of the other two screws are each installed with a second bevel gear, and the two second bevel gears are meshed with the first bevel gear. One end of the long rod is connected to a drive motor.
[0006] The middle diameter of the clamping roller is smaller than the diameters at both ends, and the upper end of the support rod is lower than the center line of the clamping roller and higher than the lower end surface of the clamping roller.
[0007] The lower end surface of the moving block is in contact with the upper surface of the bottom plate.
[0008] The outer wall of the clamping roller is provided with a protective layer.
[0009] The utility model can automatically align the position of the filter plate without manual alignment, and can lift the filter plate to be completely suspended without the need for bottom support, which is convenient for dropping materials during the punching process without avoiding the punching position.

[0013] In conjunction with the accompanying drawings, the utility model includes a base plate 1, and four groups of clamping units are evenly distributed on the horizontal circumference of the base plate 1, each group of clamping units includes a screw 2, and the screw 2 is arranged radially along the distribution circle of the clamping units. The screw 2 is rotatably installed on the base plate 1, and a moving block 3 is installed on the screw 2. The moving block 3 is threadedly matched with the screw 2, and a vertical clamping roller 4 is fixed to the upper end of the moving block 3. When the screw 2 rotates, the moving block 3 and the clamping roller 4 can be driven to move along the screw 2; a plurality of support rods 5 of equal height are provided on the base plate 1, and the filter plate to be processed is horizontally placed on the base plate 1 and supported by the support rods 5, and then the screw 2 rotates to drive the plurality of clamping rollers 4 to move synchronously toward the middle until the edge of the filter plate is clamped.
[0014] The inner ends of two co-linear screw rods 2 are fixedly connected to form a long rod, on which a first bevel gear 6 is installed, and the inner ends of the other two screw rods 2 are each installed with a second bevel gear 7, and the two second bevel gears 7 are meshed with the first bevel gear 6. One end of the long rod is connected to a drive motor 8, which drives the long rod to rotate, and the long rod drives the other two screw rods 2 to rotate through the bevel gear set, thereby realizing the synchronous inward or outward movement of the four clamping rollers 4.
[0015] The middle diameter of the clamping roller 4 is smaller than the diameters at both ends, and the upper end of the support rod 5 is lower than the center line of the clamping roller 4 and higher than the lower end surface of the clamping roller 4; in the process of the clamping roller 4 moving inward, the clamping roller 4 will lift the filter plate upward in the process of clamping the filter plate until the edge of the filter plate reaches the minimum diameter of the clamping roller 4, so that the filter plate surface after clamping is completely in a suspended state, which is convenient for dropping materials when cutting filter holes.
[0016] The lower end surface of the moving block 3 is in contact with the upper surface of the bottom plate 1 , so that the moving block 3 cannot rotate with the screw rod 2 .
[0017] The outer wall of the clamping roller 4 is provided with a protective layer, which is made of hard plastic, hard rubber and other materials to avoid indentations on the edge of the filter plate during the clamping process.
[0018] When the present invention is used, the bottom plate 1 is fixed on the workbench of the punching equipment, and a connection structure such as a T-shaped slider or a dovetail slider matching the workbench of the equipment can be arranged under the bottom plate 1; the filter plate to be punched is placed flat between a plurality of clamping rollers 4, supported by the support rod 5, and then the drive motor 8 is started, and the drive motor 8 drives the four screws 2 to rotate at the same speed through the bevel gear set. Under the action of the thread, the four clamping rollers 4 move inward synchronously, and when the clamping rollers 4 contact the edge of the filter plate, the filter plate will be lifted upward under the action of the arc-shaped outer wall of the clamping rollers 4. When it reaches the final clamping state, the centerline position of the clamping rollers 4 where the filter plate is lifted is the smallest diameter. At this time, the filter plate is in a completely suspended state, and the filter plate can be punched, and the cutting chips and falling materials can fall by themselves. After the processing is completed, the drive motor 8 is started in the reverse direction to move the clamping rollers 4 outward to loosen the filter plate, and the filter plate can be removed.
[0019] The utility model can be used for clamping the most common circular filter plates and square filter plates. The circular filter plates are clamped at four quadrant points, and the square filter plates are clamped at the midpoints of four sides. The filter plates can be automatically aligned during the clamping process without manual alignment.
[0020] In the clamping process of the utility model, the filter plate can be lifted to be completely suspended through the arc-shaped side wall of the clamping roller 4, without the need for bottom support, which facilitates the dropping of materials during the punching process without avoiding the punching position.
