Description

Technical Field

[0001] This utility model relates to the field of bolt drilling equipment technology, and in particular to a bolt drilling tooling. Background Technology

[0002] Bolt: A mechanical part, a cylindrical threaded fastener used with a nut. It consists of a head and a shank (a cylinder with external threads), and is used to fasten two parts with through holes. This type of connection is called a bolted connection. Since the two parts can be separated by unscrewing the nut, a bolted connection is a detachable connection.

[0003] A search revealed a bolt drilling fixture in publication number CN213614280U. This fixture addresses the problem that existing bolts require internal drilling, which is inconvenient due to their irregular shape and cannot be drilled for bolts of different sizes. The proposed solution includes a base with a fixed seat fixedly mounted on its top. A placement groove is formed on one side of the fixed seat, and the bolt body is placed on the bottom inner wall of the groove. A positioning hole is formed on one side of the bolt body, and a positioning pin is fixedly mounted on the bottom inner wall of the groove, engaging with the positioning hole. A fixing plate is slidably connected to the top of the base. This utility model is simple to operate, convenient to use, and can quickly position bolts, while also enabling positioning and drilling of bolts of different sizes, making it easy for users to operate.

[0004] While the above solution is simple to operate and convenient to use, and can quickly position bolts, it can also position and drill bolts of different sizes, making it easy for people to use. However, it can only fix one bolt at a time. After drilling is finished, the worker needs to remove the workpiece and replace it with a new one, which cannot guarantee the continuity of processing and results in low work efficiency. Therefore, we propose a bolt drilling tooling. Utility Model Content

[0005] The main purpose of this utility model is to provide a bolt drilling tooling. By setting a turning unit and a fixing unit, it solves the problem that only one bolt can be fixed at a time. After drilling is completed, the worker needs to remove the workpiece and replace it with a new one, which cannot guarantee the continuity of processing and results in low work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bolt drilling tooling includes a support unit, a steering unit disposed inside the support unit, a fixing unit disposed above the support unit, and a processing unit.

[0008] The steering unit includes a fixed groove inside the support unit, a rotating through hole on the top of the support unit and communicating with the fixed groove, a rotating shaft movably installed inside the support unit and passing through the rotating through hole, and an adjusting component disposed inside the support unit.

[0009] The fixing unit includes a base plate installed on the top of the rotating shaft, an inverted bracket installed on the top of the base plate, a V-groove formed in the inner bottom wall of the inverted bracket, and a clamping member disposed in the inverted bracket. The integral structure composed of the inverted bracket, the V-groove and the clamping member consists of two sets, and the two sets of integral structures composed of the inverted bracket, the V-groove and the clamping member are symmetrically arranged about the bisecting plane of the base plate.

[0010] Preferably, the support unit includes a support base and a base mounted on the bottom of the support base.

[0011] Preferably, the adjusting component includes a worm gear movably installed inside the fixed groove, a worm wheel installed on the side wall of the rotating shaft and meshing with the worm gear, and a first drive motor installed at the input end of the worm gear.

[0012] Preferably, the clamping member includes a hydraulic telescopic rod installed on the inner top wall of the U-shaped seat, and a pressure plate installed on the telescopic end of the hydraulic telescopic rod.

[0013] Preferably, the processing unit includes a fixed seat mounted on top of the support base, a threaded shaft movably mounted inside the fixed seat, a second drive motor mounted on the input end of the threaded shaft, a movable component mounted on the circumferential side of the threaded shaft, and a processing component disposed above the movable component.

[0014] Preferably, the workpiece includes a stand mounted on top of the movable part, a threaded rod movably mounted inside the stand, a movable seat mounted on the periphery of the threaded rod, a third drive motor mounted on the input end of the threaded rod, a fourth drive motor mounted on the side wall of the movable seat, and a drill bit mounted on the output end of the fourth drive motor.

[0015] Preferably, the processing unit further includes a limiting washer installed on the inner side wall of the fixed seat, and the limiting washer is sleeved on the circumferential side of the threaded shaft.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, through the configured steering and fixing units, when a bolt needs to be fixed, the bolt is placed in the V-groove on the bottom wall of the U-shaped seat. Subsequently, the extension end of the hydraulic telescopic rod extends, causing the pressure plate to press and fix the bolt. Then, the first drive motor drives the worm gear to rotate, causing the worm wheel to drive the rotating shaft to rotate synchronously, thereby causing the base plate to move the bolt in the U-shaped seat towards the side closer to the drill bit, thus achieving convenient bolt fixing. When drilling is required, the third drive motor drives the threaded rod to rotate, causing the moving seat to drive the fourth drive motor to move up and down along the threaded rod until the drill bit is aligned with the center position of the bolt. Then, the fourth drive motor drives the drill bit to rotate, and the second drive motor drives the threaded shaft to rotate, causing the moving part to move the workpiece closer to the bolt for processing. At the same time, on the side away from the drill bit, the worker can remove the processed bolt from another U-shaped seat and insert a new bolt for fixing, thus ensuring the continuity of processing and improving work efficiency.

The integral structure composed of the C-shaped seat 302, the V-shaped groove and the clamping member 303 consists of two sets, and the integral structure composed of the two sets of C-shaped seats 302, V-shaped groove and clamping member 303 is symmetrically arranged about the bisecting plane of the base plate 301. The setting of the V-shaped groove facilitates the placement and fixing of bolts.

[0033] like Figure 1 As shown, the support unit 1 includes a support base 101 and a base 102 installed at the bottom of the support base 101. The base 102 provides support for the stable operation of the entire tooling.

[0034] like Figure 4As shown, the adjusting component 202 includes a worm 2022 movably installed inside the fixed groove, a worm wheel 2021 installed on the side wall of the rotating shaft 201 and meshing with the worm 2022, and a first drive motor 2023 installed at the input end of the worm 2022. When the first drive motor 2023 drives the worm 2022 to rotate, the worm 2022 can mesh with and drive the worm wheel 2021.

[0035] like Figure 1 As shown, the clamping member 303 includes a hydraulic telescopic rod 3031 installed on the inner top wall of the C-shaped seat 302, and a pressure plate 3032 installed on the telescopic end of the hydraulic telescopic rod 3031. When the telescopic end of the hydraulic telescopic rod 3031 extends or retracts, it can drive the pressure plate 3032 to move up and down.

[0036] like Figure 2 As shown, the processing unit 4 includes a fixed base 401 mounted on the top of the support base 101, a threaded shaft 402 movably mounted inside the fixed base 401, a second drive motor 403 mounted on the input end of the threaded shaft 402, a movable part 404 mounted on the peripheral side of the threaded shaft 402, and a processing part 405 disposed above the movable part 404.

[0039] When it is necessary to fix the bolt, the bolt is placed in the V-groove on the bottom wall of the C-shaped seat 302. Then, the telescopic end of the hydraulic telescopic rod 3031 extends, causing the pressure plate 3032 to press onto the bolt for clamping and fixing. Subsequently, the first drive motor 2023 drives the worm gear 2022 to rotate, causing the worm wheel 2021 to drive the rotating shaft 201 to rotate synchronously. This causes the base plate 301 to move the bolt in the C-shaped seat 302 toward the side closer to the drill bit 4056, thus achieving convenient fixing of the bolt.
