Description

Technical Field

[0002] Filter cavity processing refers to the process of manufacturing and processing the cavity structure inside the filter used to accommodate and support electronic components. This usually includes shaping the shape of the cavity, dimensional accuracy control, surface treatment, and processing of various mounting holes, slots and other features. During the mechanical processing operations such as milling and drilling of the filter cavity, in order to ensure the processing accuracy and processing effect, corresponding clamping tooling is often used to stabilize the filter cavity.

When the filter housing is processed, the fixture is installed on the equipment workbench and is located under the power head. The housing is first placed on the placement frame, and then the first clamping component and the second clamping component are used to clamp the workpiece, and then drilling can be performed. After the processing is completed, compressed air is introduced through the air distributor seat, and then blown out through the air blowing nozzle to blow away iron chips, thereby achieving rapid removal of iron chips generated after drilling during processing, reducing the labor intensity of manual cleaning, and being more convenient to use.

Therefore, a technician in this field provides a clamping tool for CNC machining of a filter cavity to solve the problems raised in the above-mentioned background technology. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] See also Figures 1 to 4 The utility model provides a clamping tool for CNC processing of a filter cavity, comprising a bottom plate 1, four support frames 2 are slidably connected inside the bottom plate 1, a button controller 3 is fixedly connected to the left side of the bottom plate 1, an electric telescopic rod 4 is fixedly connected to the inner bottom wall of each support frame 2, a lifting plate 5 is slidably connected inside each support frame 2, a pressure sensor 8 is fixedly connected to the bottom surface of each lifting plate 5, a top plate 9 is arranged below each lifting plate 5, a plurality of identical guide rods 6 are slidably connected inside each lifting plate 5, a limiting disk 10 is fixedly connected to the top end of each guide rod 6, a small clamping plate 7 is fixedly connected to the bottom end of each guide rod 6, and a return spring 11 is sleeved on the outer surface of each guide rod 6.

[0024] The filter cavity can be placed on the bottom plate 1, and the four support frames 2 can slide in the bottom plate 1, so that after the button controller 3 controls the electric telescopic rod 4 to shorten, multiple small clamps 7 can clamp filter cavities of different sizes. At the same time, after different small clamps 7 squeeze the different concave and convex shapes of the filter cavity, they can cooperate with the top plate 9 to squeeze the return spring 11, and the return spring 11 can give the top plate 9 a reverse rebound force, and then when the pressure sensor 8 detects that the pressure from the top plate 9 reaches the value set by the button controller 3, the button controller 3 can control the corresponding electric telescopic rod 4 to stop shortening, so that the small clamps 7 under each lifting plate 5 can adapt to the different concave and convex shapes of the filter cavity and clamp the filter cavity, thereby increasing the application scenarios of a single clamping tooling.

[0025] Furthermore, the bottom surface of each lifting plate 5 is fixedly connected to the telescopic end of the electric telescopic rod 4, the outer surface of each guide rod 6 is slidably connected to the inside of the top plate 9, the bottom surface of each limit plate 10 is in contact with the upper surface of the lifting plate 5, the upper surface of each top plate 9 is in contact with the bottom surface of the pressure sensor 8, and the two ends of each return spring 11 are respectively in contact with the upper surface of the small clamping plate 7 and the bottom surface of the top plate 9. Four pads 12 are fixedly connected to the bottom surface of the bottom plate 1, and the bottom surface of each pad 12 is fixedly connected to an anti-skid and wear-resistant pad 13. By setting the pad 12, the bottom plate 1 can be raised and space for convenient movement and transportation can be left under the bottom plate 1. By setting the anti-skid and wear-resistant pad 13, it itself has good wear resistance and anti-skid properties, which can increase the stability of the entire clamping tooling when it is placed.

[0026] Furthermore, the inner wall of each support frame 2 is threadedly connected with two hand-tightening bolts 14, and the bottom end of each hand-tightening bolt 14 is in contact with the upper surface of the base plate 1. By setting the hand-tightening bolts 14, after being screwed, they can move along the inner wall threads of the support frame 2 and rise and fall relative to the base plate 1, thereby facilitating the adjustment and fixing of the position of each support frame 2 in the base plate 1.

[0027] Furthermore, the outer surface of each hand-tightening bolt 14 is fixedly connected with an anti-slip sleeve 15, and the outer surface of each anti-slip sleeve 15 is fixedly connected with a plurality of identical anti-slip bosses 16. By providing the anti-slip bosses 16, the anti-slip property of the outer surface of the anti-slip sleeve 15 can be increased. By providing the anti-slip sleeve 15 and the anti-slip bosses 16, the anti-slip property of the outer surface of the hand-tightening bolt 14 can be jointly increased.

[0028] Furthermore, the front and back sides of each lifting plate 5 are fixedly connected with a limiting slider 22, and the outer surface of each limiting slider 22 is slidably connected to the inside of the support frame 2. By setting the limiting slider 22, it can slide up and down inside the support frame 2, thereby increasing the stability of the lifting plate 5 when it is lifted or lowered.

[0029] Furthermore, the bottom surface of each small splint 7 is fixedly connected with an anti-skid pad 20, and the bottom surface of each anti-skid pad 20 is fixedly connected with a plurality of identical anti-skid convex discs 21. By providing the anti-skid convex discs 21, the anti-skid property of the bottom surface of the anti-skid pad 20 can be increased, and by providing the anti-skid pad 20 and the anti-skid convex discs 21, the anti-skid property of the bottom surface of the small splint 7 can be increased together.

[0030] Furthermore, the front and back sides of the base plate 1 are fixedly connected with handle supports 17, and the inner wall of each handle support 17 is fixedly connected with a pull rod 18. By setting the pull rod 18, a rotation base surface can be provided for the hand-gripping structure in the handle support 17, thereby increasing the flexibility of use of the hand-gripping structure. By setting the handle supports 17 and the pull rod 18, the above-mentioned hand-gripping structure can be cooperated to lift and move the entire clamping tooling.

[0031] Furthermore, a grip 19 is provided inside each handle support 17, and the inner wall of each grip 19 is rotatably connected to the outer surface of the pull rod 18. By providing the grip 19, it can rotate around the outer surface of the pull rod 18 inside the handle support 17, and then the entire clamping tool can be easily lifted and moved after being grasped by hand.

[0032] Working principle: When in use, place the filter cavity on the bottom plate 1, and slide the four support frames 2 accordingly in the bottom plate 1 according to the size of the filter cavity, until the small clamping plates 7 under each lifting plate 5 can be as much as possible above the filter cavity without affecting the subsequent processing of the filter cavity, then tighten the hand bolts 14 on each support frame 2 and tighten the hand bolts 14 to the upper surface of the bottom plate 1 to fix the position of each support frame 2, and then operate the button controller 3 to control the electric telescopic rod 4 to shorten, and then multiple small clamping plates 7 clamp the edges of filter cavities of different sizes, and at the same time, different small clamping plates 7 squeeze the different concave and convex shapes of the filter cavity. In cooperation with the top plate 9 to squeeze the return spring 11, the return spring 11 gives the top plate 9 a reverse rebound force, and then when the pressure sensor 8 detects that the pressure from the top plate 9 reaches the set value of the button controller 3, the button controller 3 automatically controls the corresponding electric telescopic rod 4 to stop shortening, so that the small clamping plate 7 under each lifting plate 5 can adapt to the positions of different concave and convex shapes of the filter cavity and clamp the filter cavity, which plays a role in increasing the application scenarios of a single clamping tool. The design of the clamping tool for CNC machining of the entire filter cavity effectively solves the problem of limited application scenarios of a single clamping tool due to the lack of an adaptive clamping structure that can adapt to filter cavities with different concave and convex shapes.
