Description

Technical Field

[0001] This utility model relates to the field of motor end cover processing technology, specifically a drilling tool for processing low-resonance explosion-proof motor end covers. Background Technology

[0002] An end cover is a rear cover installed at the back of a motor or other motor housing, commonly known as an "end cap." The quality of the end cap directly affects the quality of the motor. Special tooling is used for positioning and limiting during the machining of motor end caps.

[0003] Utility model patent CN119260431A13 discloses a tooling for drilling end caps of micro-current motors, relating to the field of motor end cap processing technology. The tooling includes a support base; a lifting platform is mounted above the support base, and the lifting platform is used to mount a cutting machine for drilling end caps; it also includes a drive cavity inside the support base, and a protective mechanism inside the drive cavity, including a shielding slide; a positioning mechanism is located in the center of the top surface of the support base. This tooling for drilling end caps of micro-current motors uses a self-locking positioning mechanism above the support base to position end caps of different specifications. The cutting machine following the lifting platform can trim and process the drilled holes. The shielding slide and the flip-type arc plate of the protective mechanism can block flying metal chips during drilling, and the metal chips are collected and discharged outwards by a conveying mechanism, thereby improving the efficiency of drilling and cutting operations.

[0004] Currently, when limiting the motor end cover, multiple limiting clamps are used to limit the left and right or front and back. This limiting method is not only cumbersome and requires multiple adjustment processes, but also has poor stability. In addition, when the tooling is installed on the object, multiple bolts are used for limiting, which is not only troublesome, but also difficult to install and remove. Utility Model Content

[0005] The purpose of this utility model is to provide a drilling fixture for machining low-resonance explosion-proof motor end caps, which solves the problems of limiting the motor end caps and installing the fixture.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling fixture for machining end caps of low-resonance explosion-proof motors, comprising a worktable, a plurality of top blocks fixedly connected to the lower end of the worktable, a base fixedly connected to the lower end of the top blocks, the base connected to the lower end of the worktable, an end cap placed on the upper end of the worktable, an mounting block connected to the lower end of the base, a limiting mechanism provided on the worktable, and an installation mechanism provided at the lower end of the base. The limiting mechanism includes a telescopic rod, a telescopic rod fixedly connected to the lower end of the worktable, a connecting rod fixedly connected to the lower end of the telescopic rod, and the connecting rod connected to the lower end of the worktable. The installation mechanism includes a lifting rod, lifting rods fixedly connected to the left and right sides of the lower end of the base, an anti-detachment block fixedly connected to the lower end of the lifting rod, a threaded sleeve fixedly connected to the anti-detachment block, and a threaded rod rotatably connected to the threaded sleeve.

[0007] Preferably, the workbench has multiple sliding holes, and a sliding rod is slidably connected inside the sliding holes. The lower end of the sliding rod is fixedly connected to the upper end of the connecting rod, and an ear plate is fixedly connected to the upper end of the sliding rod.

[0008] Preferably, the ear plate is fixedly connected to a pressure ring, the lower end of the pressure ring is fixedly connected to a ring pad, the lower pressure ring pad of the pressure ring is tightly attached to the upper end of the end cap, and the pressure ring is connected to the upper end of the worktable.

[0009] Preferably, the lower end of the threaded rod is fixedly connected to a rotating block, the lifting rod is slidably connected to a sliding sleeve, the sliding sleeve is fixedly connected to a protruding plate, and the upper end of the threaded rod is rotatably connected to the inside of the protruding plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses a telescopic rod to connect a connecting rod, which in turn connects to a sliding rod. The sliding rod connects to a pressure ring via an ear plate, thus facilitating the raising and lowering of the pressure ring via the telescopic rod. The pressure ring presses down on the upper end of the end cap, thereby surrounding and pressing down on the end cap from the upper end. This not only achieves the effect of automatic limiting but also increases the stability and convenience of limiting.

[0012] 2. This utility model uses a lifting rod limiting sliding sleeve, which is connected to a convex plate. The lower end of the lifting rod is limited by an anti-detachment block limiting threaded sleeve, which limits the threaded rod, and the threaded rod limits the convex plate. This causes the convex plate to press against the lower end of the mounting block, so that the mounting block is clamped between the worktable and the convex plate, thereby connecting the two and preventing them from loosening and separating. This achieves the installation effect and avoids the inconvenience caused by limiting with multiple bolts. Attached Figure Description

Multiple top blocks 2 are fixedly connected to the lower end of the worktable 1. A base 3 is fixedly connected to the lower end of each top block 2. The base 3 is connected to the lower end of the worktable 1. An end cap 4 is placed on the upper end of the worktable 1. A mounting block 5 is connected to the lower end of the base 3. The mounting block 5 is an external object that needs to be limited by the fixture; this is existing technology and will not be described in detail here. The worktable 1 is equipped with a limiting mechanism 6, and the lower end of the base 3 is equipped with a mounting mechanism 7. This technical solution improves upon the problems raised in the background technology. Other technical problems of this technical solution are as follows: The technology is already available, so this technical solution will not be described in detail. The limiting mechanism 6 includes a telescopic rod 61. The telescopic rod 61 is fixedly connected to the lower end of the worktable 1. The telescopic rod 61 is model YNT-03. The plug of the telescopic rod 61 is connected to an external power supply, which is existing technology. The lower end of the telescopic rod 61 is fixedly connected to a connecting rod 62. The connecting rod 62 is connected to the lower end of the worktable 1. The installation mechanism 7 includes a hanging rod 71. The lower left and right sides of the lower end of the base 3 are respectively fixedly connected to the hanging rod 71. The lower end of the hanging rod 71 is fixedly connected to an anti-detachment block 72. The anti-detachment block 72 is fixedly connected to a threaded sleeve 73. The threaded sleeve 73 is connected to a threaded rod 74 through threaded rotation.

[0020] Please see Figure 1 , Figure 2 , Figure 3 The workbench 1 has multiple sliding holes 63. A sliding rod 64 is slidably connected inside the sliding hole 63. The lower end of the sliding rod 64 is fixedly connected to the upper end of the connecting rod 62. An ear plate 65 is fixedly connected to the upper end of the sliding rod 64. A pressure ring 66 is fixedly connected to the ear plate 65. A ring pad 67 is fixedly connected to the lower end of the pressure ring 66. The ring pad 67 is used to isolate the lower end of the pressure ring 66, increase friction and anti-slip properties, and avoid direct contact that could cause damage to the end cover 4. The pressure ring 66 presses the ring pad 67 tightly against the upper end of the end cover 4. The pressure ring 66 is connected to the upper end of the workbench 1.
