Therefore, the vibration of the fixed object is reduced.

Description

Technical Field

[0001] This utility model relates to the technical field of fixing devices, and in particular to a fixing device for a working tool. Background Technology

[0002] As the division of labor in society deepens, mobile work platforms have been widely used in various industries, and these platforms inevitably need to be equipped with various professional work tools and related equipment.

[0003] Currently, most of these specialized tools and related equipment are integrated into mobile work platforms through methods such as direct placement, strapping (buckle) fixing, magnetic attraction, screwing, and welding. However, their reliability, shock absorption, ease of replacement, versatility, aesthetics, and professionalism are all somewhat lacking. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a fixing device for working tools.

[0005] This utility model provides the following technical solution: a fixing device for a working tool, comprising:

[0006] Mounting base;

[0007] The mounting base is provided with multiple movable clamping components, which together form a clamping space for accommodating the working tool.

[0008] The clamping assembly includes:

[0009] Guide rod, the guide rod being slidably connected to the mounting base;

[0010] A limiting seat is fixedly connected to the guide rod and moves with the guide rod;

[0011] A driving unit is used to drive the limiting seat to move.

[0012] An airbag unit, the airbag unit being used to fully clamp the working tool;

[0013] The airbag unit includes:

[0014] An airbag component is disposed on the limiting seat. When the clamping assembly clamps the working tool, the airbag component contacts the working tool.

[0015] An air supply component, which is used to supply gas into the airbag component and to discharge gas from the airbag component.

[0016] Furthermore, the drive unit includes a motor mounted on the mounting base and a threaded rod threadedly connected to the guide rod, the threaded rod being fixedly connected to the output shaft of the motor.

[0017] Furthermore, both the limiting seat and the airbag component are L-shaped.

[0018] Furthermore, the air supply component includes an air pump disposed on the mounting base, and an air supply pipe connecting the airbag component to the air pump, the air supply pipe being extendable.

[0019] Furthermore, the mounting base is equipped with a locking sensor. When the locking sensor receives a signal, the drive unit will drive the limiting seat to move to clamp and fix the working tool. The mounting base is also equipped with a release button. When the release button receives a signal, the drive unit will drive the limiting seat to move to no longer clamp and fix the working tool.

[0020] Furthermore, the mounting base is square, and mounting holes are provided at all four corners, through which the fixing device is mounted on the platform.

[0021] The beneficial effects of this utility model are as follows: when fixing and clamping the working tool, the airbag unit contacts the surface of the working tool; when the airbag unit inflates, it can make full contact with the working tool to make up for the fixing gap, and at the same time increase the contact surface between the limiting seat and the fixed object to increase the friction force and improve the fixing effect. Moreover, since it is the airbag unit that contacts the working tool, the airbag unit can play a buffering function, thereby reducing the vibration of the fixed object. Attached Figure Description

Detailed Implementation

[0027] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0028] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] A fixing device for a work tool, such as Figure 1 and Figure 2 As shown, it includes: a mounting base 1; and clamping components 6, wherein the mounting base 1 is provided with a plurality of movable clamping components 6, and the plurality of clamping components 6 surround to form a clamping space for accommodating the working tool.

[0031] Specifically, the mounting base 1 can be directly fixed to the mobile platform by bolts. In this embodiment, six clamping components 6 are provided, two on the front and back sides and one on the left and right sides. The six clamping components 6 surround to form a clamping space. The operator places the working tool in the clamping space, and then makes the six clamping components 6 close on the mounting base 1, thereby clamping the working tool.

[0032] like Figure 3 and Figure 4 As shown, the clamping assembly 6 includes: a guide rod 61, which is slidably connected to the mounting base 1; a limiting seat 62, which is fixedly connected to the guide rod 61 and moves with the guide rod 61; a driving unit 63, which drives the limiting seat 62 to move; and an airbag unit 64, which fully clamps the working tool.

[0033] It is understood that the airbag unit 64 is initially in a flat state. When it is necessary to clamp and fix the working tool, the operator can activate the drive unit 63. The drive unit 63 drives the guide rod 61 to move closer to the working tool. The guide rod 61 drives the limit seat 62 to move closer to the working tool. The movement of the limit seat 62 drives the airbag unit 64 to move, and the airbag unit 64 will contact the surface of the working tool. Then, the airbag unit 64 can be inflated, thereby making full contact between the airbag unit 64 and the working tool to make up for the fixing gap. At the same time, it can increase the contact surface between the limit seat 62 and the fixed object to increase the friction force and reduce the vibration of the fixed object. When it is necessary to release the object, the operator only needs to make the airbag unit 64 return to the flat state and move the limit seat 62 away from the object to release the object.

[0034] like Figure 3 and Figure 4 As shown, the airbag unit 64 includes: an airbag component 641, which is disposed on the limiting seat 62, and the airbag component 641 contacts the working tool when the clamping assembly 6 clamps the working tool; and an air supply component, which is used to supply gas into the airbag component 641 and to discharge gas from the airbag component 641.

[0035] Specifically, the air supply component includes an air pump 643 disposed on the mounting base 1, and an air supply pipe 642 connecting the airbag component 641 to the air pump 643, the air supply pipe 642 being extensible;

[0036] More specifically, the air pump 643 is a miniature air pump 643, which can be fixedly connected to the outer wall of the mounting base 1 or installed on the inner side of the mounting base 1. If installed on the inner side of the mounting base 1, the inner side of the mounting base 1 needs to have a mounting groove and a through hole communicating with the mounting groove so that the air pump 643 can pump external gas into the airbag component 641. In addition, in this embodiment, the air supply pipe 642 is preferably a spring pipe to avoid the air supply pipe 642 being blocked when the limiting seat 62 moves, so that the gas cannot be delivered to the airbag component 641. It can be understood that the operator can start the air pump 643 to input external gas into the airbag component 641 through the air supply pipe 642, or output the gas in the airbag component 641 to the outside.

[0037] like Figure 3 As shown, the drive unit 63 includes a motor 632 mounted on the mounting base 1 and a threaded rod 631 threadedly connected to the guide rod 61. The threaded rod 631 is fixedly connected to the output shaft of the motor 632.

[0038] It is understood that the motor 632 is fixedly connected to the inner side of the mounting base 1, and the guide rod 61 is a hollow structure with a threaded groove on its inner side that mates with the threaded rod 631. The threaded rod 631 is inserted into the inner side of the guide rod 61 and connected to the threaded groove on the inner side of the guide rod 61. Thus, by starting the motor 632, the motor 632 drives the threaded rod 631 to rotate, thereby causing the guide rod 61 to slide on the mounting base 1. Furthermore, in other embodiments, the drive unit 63 can be an electric actuator, which is fixedly connected to the mounting base 1 through its fixed end, and its output tube is connected to the guide rod 61, thereby activating the electric actuator to drive the guide rod 61 to move.

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, both the limiting seat 62 and the airbag component 641 are L-shaped;

[0040] It is understood that the limiting seat 62 is L-shaped, and the airbag 641 is also L-shaped, so that the bottom and outer sides of the airbag 641 are fixedly connected to the limiting seat 62. When the working tool is clamped, the lower part of the airbag 641 supports the working tool, and the upper part clamps the working tool, thereby fully clamping and fixing the working tool, and also reducing the vibration of the working tool.

[0041] like Figure 1 and Figure 2 As shown, a locking sensor 4 is provided on the mounting base 1. When the locking sensor 4 receives a signal, the drive unit 63 will drive the limiting seat 62 to move so as to clamp and fix the working tool. A release button 3 is also provided on the mounting base 1. When the release button 3 receives a signal, the drive unit 63 will drive the limiting seat 62 to move so as to no longer clamp and fix the working tool.

[0042] It is understood that the locking sensor 4 can be an infrared sensor, an ultrasonic sensor, a laser sensor, an inductive sensor, or a vision sensor; a mounting groove is provided in the upper middle part of the mounting base 1, and the locking sensor 4 is embedded in the mounting groove; the release button 3 is fixedly connected to the side wall of the mounting base 1; when the locking sensor 4 detects an object approaching, the locking sensor 4 will sense it and send a signal to the controller set inside the mounting base 1. The controller is fixedly connected to the inside of the mounting base 1. The controller will control the drive unit 63 to start, and the drive unit 63 will drive the limit seat 62 to move, so that the clamping component 6 opens outward. After the object to be fixed is placed in place, the locking sensor 4 will issue a locking command, and the controller will control the drive unit 63 to start again, so that the clamping component 6 closes and locks the object to be fixed; when it is necessary to remove the fixed object, the operator can press the release button 3. The release button 3 will send a command to the controller, and the controller will control the drive unit 63 to open the clamping component 6.

[0043] In addition, a power interface 2 is provided on the mounting base 1, which is connected to an external power source through a power structure to supply power to the electrical components inside the fixed device; in other embodiments, a storage battery can be provided on the mounting base 1 to directly supply power to the electrical components through its own storage battery.

[0044] Furthermore, in other embodiments, the setting of locking sensor 4 can be reduced, and only a button switch can be set on the mounting base 1. Pressing the button switch once can open the clamping component 6, and pressing it again can close the clamping component 6 to clamp the object.

[0045] like Figure 1 As shown, the mounting base 1 is square, and mounting holes 5 are provided at all four corners. The mounting holes 5 are used to mount the fixing device on the platform.

[0046] It is understood that the mounting base 1 has four mounting holes 5. Bolts are inserted into the mounting holes 5 and connected to the threaded holes on the moving platform, thereby installing the fixing device on the moving platform.

[0047] In summary, when the working tool is fixed and clamped, the airbag unit 64 contacts the surface of the working tool. When the airbag unit 64 inflates, it can make full contact with the working tool to compensate for the fixing gap. At the same time, it can increase the contact surface between the limiting seat 62 and the fixed object to increase the friction force and improve the fixing effect. Moreover, since the airbag unit 64 contacts the working tool, it can play a buffering role, thereby reducing the vibration of the fixed object.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent.
