[0002] The pneumatic-assisted end-face hole drilling fixture for thin-walled parts is a special tool for drilling horizontal holes in thin-walled parts. With the continuous development of technology, the structure of various electronic products, household appliances and other equipment is becoming increasingly complex, and the requirements for lightweight and miniaturization are also increasing. At present, when drilling products, radial clamping of thin-walled products can easily cause product deformation. Furthermore, when drilling end-face holes, clamping end-face holes is inconvenient, resulting in low work efficiency.

[0003] To address this issue, this utility model proposes a pneumatically assisted drilling fixture for horizontal holes in thin-walled parts with end faces. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a pneumatically assisted end-face hole drilling fixture for thin-walled parts, including a fixed base, a base plate on one side of the fixed base, a replaceable mold core mechanism fixedly connected to one side of the base plate, and a replaceable top core mechanism on one side of the base plate.

[0006] The replaceable mold core mechanism includes a vertical plate, the bottom of which is fixedly connected to the top of the base plate. A threaded rod is rotatably connected inside the vertical plate. A rotating block is fixedly connected to one side of the threaded rod. A washer is sleeved on the outside of the threaded rod. A placement block is threadedly connected to the outer surface of the threaded rod.

[0007] Preferably, in any of the above embodiments, a positioning plate is fixedly connected to one side of the vertical plate, the top of the positioning plate overlaps with the bottom of the placement block, and a placement groove is provided on one side of the placement block.

[0008] The technical effect achieved by adopting the above solution is that the operator can place the product that needs to be drilled on the end face into the placement slot in the placement block with his left hand.

[0009] Preferably, in any of the above embodiments, a crossbar is inserted inside the vertical plate, a threaded hole is provided on one side of the crossbar, a lead screw is rotatably connected inside the vertical plate, and the outside of the lead screw is threadedly connected to the inside of the threaded hole of the crossbar.

[0010] The technical effect achieved by adopting the above solution is that the operator uses his left hand to place the product that needs to be drilled for horizontal holes in thin-walled parts on the outside of one end of the crossbar.

[0011] Preferably, in any of the above embodiments, the replaceable top core mechanism includes a fixed upright plate, the bottom plate of which is fixedly connected to the top of the bottom plate by two bolts.

[0012] Preferably, one side of the fixed upright plate is fixedly connected to a cylinder, and the output end of the cylinder passes through the interior of the fixed upright plate.

Detailed Implementation

[0027] Example 1: As Figures 1 to 3 As shown, this application discloses a pneumatically assisted end-face drilling fixture for thin-walled parts with transverse holes. This application can drill end-face drilled products and also clamp thin-walled parts with transverse holes for drilling. It should be noted that this application is a semi-automatic device, requiring operators to manually cooperate with the main body 5 of the drilling equipment to drill the products. The fixture includes a fixed base 1, a base plate 2 on one side of the fixed base 1, a replaceable mold core mechanism 3 fixedly connected to one side of the base plate 2, and a replaceable top core mechanism 4 on one side of the base plate 2.

[0028] The replaceable mold core mechanism 3 includes a vertical plate 301, the bottom of which is fixedly connected to the top of the base plate 2. A threaded rod 302 is rotatably connected inside the vertical plate 301. A rotating block 303 is fixedly connected to one side of the threaded rod 302. A washer 304 is sleeved on the outside of the threaded rod 302. A placement block 305 is threadedly connected to the outer surface of the threaded rod 302. When drilling a product with a hole drilled at the end face, the operator first places the placement block 305 on the positioning plate 306. Use your right hand to keep the placement block relatively stable, then use your left hand to pass the threaded rod 302 through the vertical plate 301, and then use your left hand to rotate the rotating block 303, so that the rotating block 303 drives the threaded rod 302 to rotate inside the vertical plate 301. At this time, the threaded rod 302 will rotate into the interior of the placement block 305, thereby installing the placement block 305. It should be noted that after the placement block 305 is installed, the gasket 304 will be placed between the rotating block 303 and the vertical plate 301 for isolation and protection.

[0029] A positioning plate 306 is fixedly connected to one side of the vertical plate 301. The positioning plate 306 keeps the placement block 305 horizontal, so that the product with the end face drilled is kept horizontal, which facilitates the drilling work of the main body 5 of the drilling equipment. The top of the positioning plate 306 overlaps with the bottom of the placement block 305. A placement groove is opened on one side of the placement block 305. When drilling, the operator places the product to be drilled on the end face into the placement groove in the placement block 305 with his left hand, and operates the cylinder 402 with his right hand, so that the top core 404 clamps the product with the end face drilled from the side. Then, the operator uses his right hand to operate the main body 5 of the drilling equipment to lower and drill the product with the end face drilled. Then, the left and right hands work together to repeat this work to drill the product with the end face drilled. This method can facilitate the clamping and fixing of the product with the end face drilled, and can also increase the speed of the operator when loading and unloading materials, thereby improving work efficiency.

[0030] Example 2: Figures 4 to 6As shown, a horizontal bar 307 is inserted into the interior of the vertical plate 301. A threaded hole is provided on one side of the horizontal bar 307. A lead screw 308 is rotatably connected inside the vertical plate 301. The outside of the lead screw 308 is threadedly connected to the inside of the threaded hole of the horizontal bar 307. When drilling is required for a product with a thin-walled horizontal hole, the operator first disassembles the placement block 305, then inserts the horizontal bar 307 into the vertical plate 301 and through it. Then, the lead screw 308 is rotated, causing it to rotate inside the vertical plate 301. At this time, the lead screw 308 will rotate into the threaded hole on one side of the horizontal bar 307, thereby fixing the horizontal bar 307. It should be noted that the through hole into which the horizontal bar 307 is inserted into the vertical plate 301 is not the same through hole as the through hole through which the threaded bar 302 passes through the vertical plate 301. The height of the horizontal bar 307 through the through hole of the vertical plate 301 is higher than the height of the threaded bar 302 through the through hole of the vertical plate 301.

[0031] After the crossbar 307 is installed and fixed, the operator uses their left hand to place the product for which horizontal holes need to be drilled on one end of the crossbar 307, noting that this end is the one closest to the top core 404. Then, the operator uses their right hand to operate the cylinder 402, causing the top core 404 to axially clamp and fix the product for horizontal hole drilling. This avoids product deformation when radially clamping thin-walled products. Subsequently, the same operation as the drilling equipment body 5 in the embodiment is used to drill the product for horizontal hole drilling. Then, the operator removes the product after the drilling is completed. This method can still improve the speed of loading and unloading products, thereby improving the operator's work efficiency.

[0032] The replaceable top core mechanism 4 includes a fixed upright plate 401, and the base plate 2 of the fixed upright plate 401 is connected and fixed to the top of the base plate 2 by two bolts.

[0033] A cylinder 402 is fixedly connected to one side of the fixed upright plate 401. The output end of the cylinder 402 passes through the interior of the fixed upright plate 401. The body of the cylinder 402 is connected to a cylinder manual reversing valve through two connecting pipes. When the operator operates the cylinder 402, he / she mainly uses his / her right hand to operate the cylinder manual reversing valve to move the output end of the cylinder 402. The cylinder manual reversing valve is a known technology, and those skilled in the art can and should understand its specific function and structure.

[0034] The output end of cylinder 402 is fixedly connected to a threaded connector 403. The outer surface of the threaded connector 403 is threaded with a core 404. The core 404 is made of nylon. The product is clamped and fixed by the core 404 made of nylon, which can avoid damage to the product. Because nylon is relatively soft compared to metal, it can protect the product from damage by the core 404 when clamping the product.

[0035] When the top core 404 needs to be replaced, the operator rotates the top core 404 so that it rotates outside the threaded joint 403, thereby installing or removing the top core 404 outside the output end of the cylinder 402.

[0036] When clamping and fixing the product, the operator uses his right hand to control the manual reversing valve of the cylinder, so that the output end of the cylinder 402 drives the top core 404 to move, thereby clamping and fixing or releasing the product.

[0037] The bottom side of the base plate 2 is fixed to the top of the fixing seat 1 by two bolts. A fixing column 101 is fixedly connected to one side of the fixing seat 1, and a drilling equipment body 5 is fixedly connected to one side of the fixing column 101. After the product is clamped and fixed, the drilling equipment body 5 is used to drill the product. The operator mainly lowers the drill bit of the drilling equipment body 5 by pressing the handle on one side of the drilling equipment body 5 to drill the product. Since the technology of the drilling equipment body 5 is already very mature, this utility model has not improved it, so it will not be described in detail here. At the same time, those skilled in the art can and should understand its specific function and structure.

[0038] The working principle of the pneumatically assisted drilling fixture for transverse holes in thin-walled parts with end faces is as follows:

[0039] First, this application can drill holes in products with end face drilling while simultaneously drilling holes in thin-walled parts with transverse holes. It should be noted that this application is a semi-automatic device, requiring operators to manually cooperate with the main body 5 of the drilling equipment to drill the products. The body of cylinder 402 is connected to a manual cylinder reversing valve through two connecting pipes. When operating cylinder 402, the operator mainly uses the right hand to operate the manual cylinder reversing valve to move the output end of cylinder 402. When clamping and fixing the product, the operator uses the right hand to control the manual cylinder reversing valve, causing the output end of cylinder 402 to drive the top core 404 to move, thereby clamping and fixing or releasing the product.

[0040] Secondly, when drilling products with end face drilling, the operator first places the placement block 305 on the positioning plate 306 and uses the right hand to keep the placement block relatively stable. Then, the left hand passes the threaded rod 302 through the vertical plate 301, and then the left hand rotates the rotating block 303, so that the rotating block 303 drives the threaded rod 302 to rotate inside the vertical plate 301. At this time, the threaded rod 302 will rotate into the interior of the placement block 305, thereby installing the placement block 305. When drilling, the operator places the product that needs to be drilled on the end face in the placement groove of the placement block 305 with the left hand, and uses the right hand to operate the cylinder 402, so that the top core 404 clamps the product with the end face drilling from the side. Then, the right hand operates the main body 5 of the drilling equipment to descend and drill the product with the end face drilling. Then, the left and right hands work together to repeat this work to drill the product with the end face drilling.

[0041] Finally, when drilling is required on a thin-walled part with a horizontal hole, the operator first disassembles the placement block 305, then inserts the crossbar 307 into the vertical plate 301 and through it. Next, the lead screw 308 is rotated, causing it to rotate inside the vertical plate 301. At this point, the lead screw 308 rotates into the threaded hole on one side of the crossbar 307, thus fixing the crossbar 307. After the crossbar 307 is installed and fixed, the operator uses their left hand to place the product requiring horizontal hole drilling onto one side of the crossbar 307. Externally, note that this end is the one closest to the top core 404. Then, the cylinder 402 is operated with the right hand, so that the top core 404 axially clamps and fixes the product with horizontal hole drilling in the thin-walled part. This can avoid product deformation when radially clamping the thin-walled product. Then, the same operation as the drilling equipment body 5 in the embodiment is used to drill the product with horizontal hole drilling in the thin-walled part. Then the operator removes the product after the drilling is completed. This method can still improve the speed of the operator when loading and unloading products, thereby improving its work efficiency.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
