Description

Technical Field

[0001] The present disclosure relates to a supporting device, in particular to a supporting device for supporting a handheld tool. Background Art

[0002] In vehicle manufacturing plants, there are many processes involving tightening and assembly on the production line. For example, the main production process of the vehicle assembly workshop is to assemble hundreds of parts through bolt connections, from the installation of engines, gearboxes, tires, seats, anti-collision beams, etc. to the fixing of seat belts, lights, door handles, etc., all are assembled by tightening various screws and nuts together. A large part of the bolt connection directly affects the safety and functionality of the vehicle, and directly or indirectly affects the safety of the driver and passengers.

[0003] In vehicle manufacturing plants, in order to improve work efficiency, reduce work intensity, and ensure work quality, some handheld tools are widely used for tightening and assembly, such as manual torque wrenches, mechanical torque wrenches, torque wrenches with batteries, handheld electric control wrenches with control systems (EC wrenches), etc. Among them, EC wrenches have high-precision sensors and intelligent control systems, which can monitor and accurately control torque in real time to ensure the tightening quality of bolts. They are usually used in operations that require high tightening accuracy and high torque.

[0004] Collisions or drops will directly affect the accuracy of such handheld tools. In addition, such handheld tools are expensive, resulting in high maintenance costs. For example, EC wrenches are expensive (average prices range from more than 100,000 to more than 200,000) precision equipment, and must be strictly prevented from falling or collisions. Such handheld tools are heavy in themselves, for example, weighing 2-3 kg, and handheld tools with high torque weigh even more. Furthermore, when working, the operator himself needs to withstand the reaction force of such handheld tools when working. In the case of operations requiring high-torque handheld tools, such as 108 Nm, long-term tightening work will consume a lot of physical strength of the operator.

[0005] In order to reduce the weight of the operator, reduce the reaction force transmitted to the operator when the handheld tool is working, and avoid the handheld tool from accidentally falling or colliding, an auxiliary robot arm is usually used to hang the handheld tool on the track above the workstation. The auxiliary robot arm can bear the weight of the handheld tool and absorb part of its reaction force. The track above allows the operator to guide the handheld tool to move forward, backward, left, and right along the track within a certain range, so that the handheld tool can be used within the range of 1-2 adjacent workstations. However, the auxiliary robot arm and the supporting track have limited flexibility, occupy a large space, and are expensive.

[0006] When performing line balancing on the installation of spare parts for the production line in a workshop, if the change in the process requires changing the workstation where the handheld tool is used, either the workstation where the handheld tool is used can only be adjusted to a workstation adjacent to the original workstation without changing the position of the robotic arm and the track, or the robotic arm and the supporting track need to be completely disassembled and then reinstalled to the workstation after line balancing. This process is complicated and costly, so the robotic arm of the handheld tool and the supporting track fixed above the workstation greatly limit the line balancing work. Utility Model Content

[0051] Figures 1 to 5 A supporting device 1 according to an embodiment of the present disclosure is shown, which can be used to carry a handheld tool.

[0052] In some embodiments according to the present disclosure, a handheld tool (not shown) may generally include a gripping portion for grasping the handheld tool and an operating portion for performing an operation (e.g., performing a tightening action). The gripping portion may generally be in the form of an elongated handle suitable for grasping. Components for controlling or displaying the operation of the operating portion, such as a switch, a display screen, an indicator light, etc., may be provided on the gripping portion. An anti-slip component may also generally be provided on the gripping portion to increase the friction when the operator grasps. The operating portion may generally be provided on one end of the gripping portion and include various types of tool heads for performing the operation. The other end of the gripping portion may generally be used to install a battery module. For some handheld tools that need to provide a large torque, the other end of the gripping portion may be directly connected to a power source via an electric wire. When using the handheld tool, the operator may grip the gripping portion so that the operating portion is aligned with the operating area for operation. For a handheld tool with a greater torque, the greater the reaction force transmitted to the operator through the gripping portion when it is working.

[0053] The supporting device 1 may include a base 10 supported on the ground and a supporting mechanism 20 disposed on the base and used for supporting a handheld tool.

[0054] The carrying mechanism 20 can be configured to accommodate at least a portion of the gripping portion of the handheld tool. The carrying mechanism 20 can also be configured to accommodate the entire gripping portion of the handheld tool, so that the carrying mechanism and the gripping portion of the handheld tool are combined into a whole to stably carry the handheld tool. The carrying mechanism can also be configured to accommodate an auxiliary support member (not shown). The auxiliary support member is configured so that when the handheld tool is held on the support device and works, the reaction force generated by it can be transmitted to the base 10 and the auxiliary support member through the carrying mechanism.

[0055] The support device disclosed in the present invention allows the weight of the handheld tool to be borne by the bearing mechanism 20, so that the operator does not need to bear the weight of the handheld tool, nor does he need to worry about the handheld tool falling, thereby reducing the risk of the handheld tool being damaged by collision. The support device disclosed in the present invention also allows the operator to avoid resisting the strong reaction force of the handheld tool during work, thereby reducing the operator's work intensity.

[0056] The supporting mechanism 20 may include a bracket 201. The bracket may be configured to accommodate and fit tightly with at least a portion of a gripping portion of a handheld tool. The bracket 201 may be manually oriented by an operator. In the implementation shown in the drawings, the direction of the bracket 201 may be changed by tightening or loosening a threaded knob 205. According to one embodiment of the present disclosure, a groove may be provided in the bracket 201, and the size of the groove may be set so that at least a portion of a gripping portion of a handheld tool may be inserted into and clamped in the groove. In the embodiment shown in the drawings, the bracket 201 may be provided with a sleeve 202 (such as Figure 5 As shown in FIG. 2 , at least a portion of the gripping portion of the handheld tool is adapted to be received in and tightly fitted with the sleeve 202. The bracket 201 enables the handheld tool to be held on the supporting device 1.

[0057] The supporting mechanism 20 may include a connector 203 for receiving an auxiliary support member. The auxiliary support member may be detachably mounted to the connector 203 of the supporting mechanism. In some embodiments, the auxiliary support member and the connector may be connected by threaded connection, snap connection, etc. According to one embodiment of the present disclosure, the auxiliary support member may also be directly inserted into the connector 203. This facilitates the operator to install, remove or replace the auxiliary support member as needed.

[0058] In order to cooperate with the working state of the hand-held tool in the bracket 201, the auxiliary support member can be arranged to extend downward from the connecting member 203 of the supporting mechanism 20 until it rests on the ground. In some embodiments, the auxiliary support member can also be manually oriented by the operator (for example, by tightening or loosening a threaded knob to change the direction of the connecting member) and fixed, so that the direction of the auxiliary support member can be arranged to be suitable for resisting the reaction force of the hand-held tool. This allows the auxiliary support member to resist the reaction force generated when the hand-held tool is working by resting on the ground. In some embodiments of the present disclosure, the direction of the auxiliary support member is parallel to the gripping portion of the hand-held tool in the working state, so that the reaction force of the hand-held tool with a large torque can be resisted.

[0059] The auxiliary support member may be configured as a rod with a fixed length. The auxiliary support member may also be configured as a rod with an adjustable length. According to one embodiment of the present disclosure, the auxiliary support member may be a telescopic rod. According to another embodiment of the present disclosure, the auxiliary support member may be a rod formed by a plurality of rod-shaped elements being threadedly connected to each other, and the length of the auxiliary support member may be changed by adding or removing rod-shaped elements. This makes it easy for the auxiliary support member to match the ground in different situations, so as to remain effectively against the ground, or effectively against other surfaces, to counteract the reaction force generated when the handheld tool is working.

[0060] The bracket 201 and the connecting member 203 can be made into a single component. In the embodiment shown in the drawings, the connecting member 203 is provided in the bracket 201 in the form of a connecting hole. In some embodiments of the present disclosure, the connecting hole and the sleeve 202 can be provided in parallel in the bracket 201. This makes it easy to arrange the auxiliary support member parallel to the gripping portion of the handheld tool, which is conducive to the auxiliary support member resisting the reaction force generated when the handheld tool is working by abutting against the ground.

[0061] The carrier mechanism 20 may include a locking member. The locking member may be used to lock at least a portion of the gripping portion of the handheld tool in the bracket and / or to lock the auxiliary support member in the connecting member. In the embodiment shown in the drawings, the locking member is a screw 206 and a screw 204. The screw 206 can clamp the sleeve 202 to the gripping portion of the handheld tool arranged in the sleeve. The screw 204 can lock the auxiliary support member on the connecting member 203. The locking member may also be one or more of a hoop element, a belt element, a buckle element, or other similar locking members.

[0062] The supporting mechanism 20 can be arranged to be fixed relative to the base 10. According to one embodiment of the present disclosure, the supporting mechanism 20 and the base 10 can be made into a single component. According to another embodiment of the present disclosure, the supporting mechanism 20 can also be fixed to the base 10 in a known manner. For example, the supporting mechanism 20 is fixed to the base by screw connection, threaded connection, welding, etc.

[0063] The supporting mechanism 20 may also be configured to be movably mounted on the base 10. The supporting mechanism 20 may be positioned in an initial position or at least one other working position relative to the base 10. The initial position of the supporting mechanism 20 may be a statically stable position where the handheld tool supported by it is not working. The initial position of the supporting mechanism 20 may also be the initial working position or the working position under normal conditions of the handheld tool supported by it. At least one other working position of the supporting mechanism 20 may be a special working position or a temporary working position of the handheld tool supported by it. In one embodiment of the present disclosure, when the handheld tool needs to work at different heights, the supporting mechanism 20 may be temporarily moved relative to the base 10 to at least one other working position different from the initial position. This ensures that the working range of the handheld tool on the supporting device 1 will not be limited by the structure of the supporting device itself.

[0064] According to one embodiment of the present disclosure, the support device 1 may include at least one latch and associated holes disposed in the carrier mechanism 20 and the base 10. The carrier mechanism may be positioned relative to the base by inserting the latch into a hole of the carrier mechanism 20 and a hole of the base 10 aligned therewith. In some embodiments, the positioning height of the carrier mechanism relative to the base may be changed by aligning holes at different heights of the carrier mechanism with holes at different heights of the base and inserting the latch.

[0065] The support device 1 may include a positioning guide mechanism 30. The positioning guide mechanism 30 may be arranged between the carrying mechanism 20 and the base 10 to guide the movement of the carrying mechanism 20 on the base 10. The positioning guide mechanism 30 may include a first guide member 301 arranged in the carrying mechanism 20 and a second guide member 302 arranged in the base 10 for cooperating with the first guide member 301. In the embodiment shown in the drawings, the first guide member 301 in the carrying mechanism 20 may be a groove, and the second guide member 302 in the base 10 may be a guide rail. According to one embodiment of the present disclosure, the first guide member in the carrying mechanism 20 may be a guide rail, and the second guide member in the base 10 may be a groove. The carrying mechanism 20 may be moved and positioned relative to the base 10 under the cooperation of the groove and the guide rail. In some embodiments, the groove and the guide rail may be arranged in a straight line, for example, in a vertical direction or in a horizontal direction or in an oblique straight line direction, so that the carrying mechanism 20 may be moved and positioned relative to the base 10 along the vertical direction or in the horizontal direction or in an oblique straight line direction. In other embodiments, the first guide member 301 may be a protrusion, and the second guide member 302 may be a groove, and the protrusion may move in the groove. In some embodiments, the protrusion may slide in a groove arranged in a cross shape or a Z shape, so that the supporting mechanism 20 may be moved and positioned relative to the base 10 along the cross shape or the Z shape groove. The groove and the guide rail, or the protrusion and the groove may also be arranged in an arc direction, so that the supporting mechanism may be moved and positioned relative to the base along the arc direction.

[0066] The support device 1 may include a limiting mechanism. The limiting mechanism may be provided in the positioning guide mechanism to limit the range of movement of the supporting mechanism relative to the base. According to one embodiment of the present disclosure, the limiting mechanism may be provided at the end of the guide rail in the base 10 to prevent the groove in the supporting mechanism 20 from detaching from the guide rail from the end of the guide rail when the groove moves along the guide rail in the base 10. In other embodiments of the present disclosure, the limiting mechanism may also be installed at a predetermined position of the guide rail in a known detachable manner (e.g., by snap connection, threaded connection, etc.) so as to limit the range of movement of the supporting mechanism relative to the base as required. The limiting mechanism makes it possible to avoid the risk of damage to the handheld tool caused by the supporting mechanism moving outside the base.

[0067] The support device 1 may include a reset mechanism. The reset mechanism may be arranged between the carrier mechanism and the base.
