Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bolt connection devices, specifically a bolt connection device. Background Technology
[0002] In daily life, we often need to connect and fix two or more parts. There are many ways to fix them, such as welding, snap-fitting, binding and bolting. In comparison, welding is difficult to disassemble once it is welded, which is too limiting. Snap-fitting and binding are easy to loosen and are not suitable for connecting parts with high fastening requirements. Only bolting can take into account both fastening and mobility. Therefore, bolts have become the most widely used connection device in our daily lives.
[0003] In existing technologies, bolt connection devices typically use mechanical tools such as wrenches and sockets to install bolts. However, existing bolt connection devices generally require changing different types of wrenches and sockets depending on the type of bolt, making the operation complex and requiring the carrying of a large number of tools, which puts a certain burden on the workers. Utility Model Content
[0004] The purpose of this utility model is to provide a bolt connection device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A bolted connection device includes: a housing, a circular shell, an adjusting mechanism, and a rotating mechanism. The circular shell is rotatably connected to the bottom of the housing. The adjusting mechanism is disposed inside the circular shell, and the rotating mechanism is disposed inside the housing. The adjusting mechanism includes a triangular block, a trapezoidal block, and a clamping rod. A limiting hole is provided at the bottom of the circular shell. The clamping rod passes through the limiting hole and is slidably connected to the limiting hole. The trapezoidal block is fixedly connected to the outer wall of the clamping rod and is located inside the circular shell. The triangular block is disposed inside the circular shell, and its inclined surface contacts the inclined surface of the trapezoidal block.
[0007] Preferably, an electric push rod is fixedly installed on the top of the inner wall of the circular shell, and the output end of the electric push rod is fixedly connected to a circular plate via a telescopic rod. A connecting rod is fixedly connected to the bottom of the circular plate, and the triangular block is fixedly connected to the bottom of the connecting rod. By setting the electric push rod, the triangular block can be driven to squeeze the trapezoidal block.
[0008] Preferably, a circular block is fixedly connected to the bottom of the inner wall of the circular shell, and a limiting rod is fixedly connected to the outer wall of the circular block. The limiting rod passes through the clamping rod and is slidably connected to it. The limiting rod is provided to ensure that the clamping rod moves stably.
[0009] Preferably, a spring is sleeved on the outer wall of the limiting rod, and the two ends of the spring are fixedly connected to the outer wall of the clamping rod and the outer wall of the circular block, respectively. By setting the spring, the clamping rod can be driven to reset.
[0010] Preferably, the outer wall of the clamping rod is provided with an anti-slip groove, and the number of clamping rods, limiting rods and springs are all six, arranged in a circumferential array. By setting six clamping rods, the device can clamp the nut of the bolt more firmly, and the anti-slip groove can increase the friction during clamping, further improving the clamping firmness.
[0011] Preferably, the rotating mechanism includes a fixed plate and a motor. The fixed plate is fixedly connected inside the housing, and the motor is fixedly mounted on the top of the fixed plate. The output shaft of the motor is fixedly connected to the top of the circular housing, and the output shaft passes through the fixed plate and is rotatably connected to the fixed plate.
[0012] Preferably, a bearing is provided inside the outer shell, and the bearing is fixedly installed inside the outer shell by two connecting blocks. A vertical rod is fixedly connected to the top of the round shell, and the outer wall of the vertical rod is fixedly connected to the inner ring of the bearing.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. After the bolts are pre-connected, the bolt nuts are placed between the six clamping rods. The electric push rod is activated to move the circular plate downward. The circular plate, through the connecting rod, causes the triangular block to press against the trapezoidal block. The trapezoidal block, under pressure, moves the clamping rods closer to the bolt nuts, thereby fixing the bolt nuts. Then the connecting bolts can be rotated. By adjusting the position of the six clamping rods, the device can connect bolts of different sizes without requiring workers to carry a lot of tools, thus providing convenience for workers.
[0015] 2. By using six clamping rods to clamp the bolt nuts, the motor is started to drive the circular shell to rotate through the output shaft, thereby causing the clamped bolts to rotate, which facilitates connection. The bearings and vertical rods make the rotation of the circular shell more stable, improving the stability of the device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1-4 As shown, a bolt connection device includes a housing 1, a circular shell 2, an adjusting mechanism 3, and a rotating mechanism 4. The circular shell 2 is rotatably connected to the bottom of the housing 1. The adjusting mechanism 3 is located inside the circular shell 2, and the rotating mechanism 4 is located inside the housing 1. A cover plate is detachably connected to the front of the housing 1 for easy maintenance of the device. A battery is installed inside the housing 1, which is existing technology and will not be described in detail. The adjusting mechanism 3 includes a triangular block 34, a trapezoidal block 35, and a clamping rod 36. A limit hole is formed at the bottom of the circular shell 2. The clamping rod 36 passes through the limit hole and is slidably connected to it. The trapezoidal block 35 is fixedly connected to the outer wall of the clamping rod 36 and is located inside the circular shell 2. The triangular block 34 is located inside the circular shell 2, and its inclined surface contacts the inclined surface of the trapezoidal block 35. An electric push rod 31 is fixedly installed on the top of the inner wall of the circular shell 2. The output end of the electric push rod 31 is fixedly connected to a circular plate 32 via a telescopic rod. A connecting rod 33 is fixedly connected to the bottom of the circular plate 32. The triangular block 34 is fixedly connected to the connecting rod 34. At the bottom of the connecting rod 33, there are six triangular blocks 34, six connecting rods 33 and six trapezoidal blocks 35 arranged in a circular array. The electric push rod 31 can drive the triangular blocks 34 to press the trapezoidal blocks 35. A circular block 38 is fixedly connected to the bottom of the inner wall of the circular shell 2. A limit rod 37 is fixedly connected to the outer wall of the circular block 38. The limit rod 37 passes through the clamping rod 36 and is slidably connected to the clamping rod 36. The limit rod 37 is set to make the clamping rod 36 move stably. A spring 39 is sleeved on the outer wall of the limit rod 37. The two ends of the spring 39 are fixedly connected to the outer wall of the clamping rod 36 and the outer wall of the circular block 38, respectively. The spring 39 can drive the clamping rod 36 to reset. The outer wall of the clamping rod 36 has an anti-slip groove. There are six clamping rods 36, six limit rods 37 and six springs 39 arranged in a circular array. The six clamping rods 36 make the device clamp the bolt nuts more firmly, and the anti-slip groove can increase the friction during clamping, further improving the clamping firmness.
[0023] Specifically, after the bolts are pre-connected, the bolt nuts are placed between the six clamping rods 36. The electric push rod 31 is activated to move the circular plate 32 downward. The circular plate 32, through the connecting rod 33, drives the triangular block 34 to press the trapezoidal block 35. The trapezoidal block 35, under pressure, moves the clamping rods 36 closer to the bolt nuts, thereby fixing the bolt nuts. Then the connecting bolt can be rotated. By adjusting the position of the six clamping rods 36, the device can connect bolts of different types without requiring workers to carry a lot of tools, thus providing convenience for workers.
[0024] like Figure 2-3 As shown, the rotating mechanism 4 includes a fixed plate 41 and a motor 42. The fixed plate 41 is fixedly connected inside the outer shell 1, and the motor 42 is fixedly installed on the top of the fixed plate 41. The output shaft of the motor 42 is fixedly connected to the top of the circular shell 2, and the output shaft passes through the fixed plate 41 and is rotatably connected to the fixed plate 41. A bearing 43 is provided inside the outer shell 1, and the bearing 43 is fixedly installed inside the outer shell 1 through two connecting blocks 45. A vertical rod 44 is fixedly connected to the top of the circular shell 2. The outer wall of the vertical rod 44 is fixedly connected to the inner ring of the bearing 43. There are six vertical rods 44 arranged in a circular array. A circular hole is provided at the bottom of the outer shell 1 so that the vertical rods 44 can pass through.
[0025] Specifically, after clamping the bolt nuts with six clamping rods 36, the motor 42 is started so that it drives the circular shell 2 to rotate through the output shaft, thereby driving the clamped bolt to rotate, which facilitates the connection. In addition, the bearing 43 and the vertical rod 44 make the rotation of the circular shell 2 more stable and improve the stability of the device.
[0026] Furthermore, the device is powered by a built-in battery, and both the motor 42 and the electric push rod 31 are controlled by a controller. These are existing technologies and are not the main innovations of this application, so they will not be described in detail here.
[0027] The working principle of this utility model is as follows: After the bolts are pre-connected, the bolt nuts are placed between the six clamping rods 36. The electric push rod 31 is activated to drive the circular plate 32 to move down. The circular plate 32 drives the triangular block 34 to press the trapezoidal block 35 through the connecting rod 33. The trapezoidal block 35 is pressed and drives the clamping rods 36 to approach the bolt nuts, thereby fixing the bolt nuts. Then the connecting bolt can be rotated. By adjusting the position of the six clamping rods 36, the device can connect bolts of different types without requiring workers to carry a lot of tools, providing convenience for workers. After the bolt nuts are clamped by the six clamping rods 36, the motor 42 is activated to drive the circular shell 2 to rotate through the output shaft, thereby driving the clamped bolt to rotate, which facilitates the connection. The bearing 43 and the vertical rod 44 make the rotation of the circular shell 2 more stable, improving the stability of the device.
