DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other implementation methods obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0030] The inventive concept of the present application is described here:

[0031] The driving arm is an important power transmission component and is widely used in production equipment. It transmits the power (such as torque or thrust) generated by the power device 2 (such as a motor) to each processing unit 3, so that the processing unit 3 performs various movements.

[0032] The driving arm is usually made of metal or other solid materials, and needs sufficient strength and rigidity to withstand the force and torque generated by the power device 2. During the production and processing process, the driving arm needs to receive the force and torque generated by the power device 2 for a long time. Since the strength and rigidity of the power device 2 are much worse than those of the driving arm, the power device 2 is easily damaged during this process. When the power device 2 is damaged, the power device 2 and the driving arm need to be disassembled. The driving arm is usually an integral block structure and has a large weight, which makes the disassembly process of the power device 2 and the driving arm more complicated. It is usually necessary to first remove the mechanical arm and the power device 2 on the production equipment as a whole, and then remove the power device 2 from the driving arm before replacing the driving arm. Since the weight of the driving arm is usually large, it is difficult to remove the entire driving arm, and it usually requires the cooperation of multiple people to complete it, and the operation is relatively complicated. Similarly, the installation process of the power device 2 and the driving arm is also relatively complicated.

[0033] Based on this, the inventor provides a driving arm. During the replacement of the power device 2, only part of the structure of the power device 2 and the driving arm needs to be removed, which simplifies the disassembly and installation process of the power device 2 and the driving arm.

[0034] The following is combined with Figures 1 to 7 , the driving arm 1 provided in the present application is described in detail through specific embodiments and application scenarios.

[0035] Please also see Figure 1 and Figure 2 An embodiment of the present application provides a driving arm 1 , which may include a main body 10 and a first connecting member 20 , wherein the first connecting member 20 may be detachably connected to the main body 10 .

[0036] Specifically, the body 10 can be configured as a long strip and extend in the first direction. Figure 1 As shown, in this embodiment, the first direction is a direction extending to the right. The body 10 may include a first surface 110, a second surface 120 and a third surface 130 disposed adjacent to each other, wherein the first surface 110 and the second surface 120 extend in the first direction, that is, the third surface 130 is an end surface of the body 10. Figure 3 A first mounting portion 111 may be provided on the first surface 110 , and the first mounting portion 111 may be used for detachable connection with the first connecting member 20 .

[0037] Please also see Figure 3 and Figure 4 In this embodiment, the body 10 may include a first structure portion 140 and a second structure portion 150 on a path extending along the first direction, wherein the cross-sectional dimension of the first structure portion 140 is smaller than the cross-sectional dimension of the second structure portion 150, and the first mounting portion 111 may be disposed on the second structure portion 150. It is understandable that since the second structure portion 150 needs to be connected to the first connector 20, the second structure portion 150 needs to bear a greater load, so increasing the cross-sectional dimension of the second structure portion 150 can increase the structural strength and stability of the second structure portion 150, thereby avoiding or reducing the possibility of damage to the second structure portion 150 during operation.

[0038] It should be noted that, in order to avoid damage to the body 10 due to stress concentration, in a preferred embodiment, the body 10 may further include a third structure portion 160 on the path extending along the first direction, and the cross-sectional size of the third structure portion 160 is larger than the cross-sectional size of the first structure portion 140 and smaller than the cross-sectional size of the second structure portion 150. In this embodiment, the provision of the third structure portion 160 can make the transition between the first structure portion 140 and the second structure portion 150 smoother, thereby avoiding the phenomenon of stress concentration at the junction of the first structure portion 140 and the second structure portion 150. It is understandable that the embodiment of the present application does not limit the specific number of the third structure portion 160, and can be determined according to actual conditions such as the specific length of the body 10.

[0039] Please also see Figure 3 and Figure 5, the first connecting member 20 may be disposed on the first surface 110, and the first connecting member 20 may be provided with a second mounting portion 220 that cooperates with the first mounting portion 111. The embodiment of the present application does not limit the specific structure and form of the first mounting portion 111 and the second mounting portion 220. For example, in one embodiment, the first mounting portion 111 and the second mounting portion 220 may cooperate in the form of a convex block and a slot, or the first mounting portion 111 and the second mounting portion 220 may cooperate in the form of a convex block and a slot, that is, in this embodiment, one of the first mounting portion 111 and the second mounting portion 220 is a convex block, and the other is a slot or a slot. In other embodiments, the first mounting portion 111 and the second mounting portion 220 may also cooperate in the form of a screw connection.

[0040] In this embodiment, the first mounting portion 111 is a protrusion, the second mounting portion 220 is a clamping hole, and a screw hole is opened on the first surface 110, and the first connecting member 20 is also penetrated by a screw hole. In this embodiment, the first connecting member 20 and the main body 10 are connected by both clamping and screw connection, which improves the stability of the connection between the first connecting member 20 and the main body 10, and avoids or reduces the possibility of the first connecting member 20 and the main body 10 falling off during normal operation of the driving arm 1.

[0041] In a specific embodiment, the first surface 110 has a recessed area 112, and the first mounting portion 111 can be arranged in the recessed area 112. When the first connecting member 20 is connected to the main body 10, the surface of the first connecting member 20 is flush with other areas of the first surface 110 except the recessed area 112. In this way, the first connecting member 20 can be prevented from protruding from the first surface 110, which is not only beneficial to improving the aesthetics of the entire driving arm 1, but also can avoid or reduce the damage of the first connecting member 20 by the external environment.

[0042] In addition, in this embodiment, at least a partial area of ​​the first connecting member 20 extends out of the main body 10 in the first direction, which makes it easy to connect the first connecting member 20 to external equipment. For example, the first connecting member 20 can be used to connect the power device 2 and / or the processing unit 3.

[0043] Specifically, the first connecting member 20 may include an extending portion 230 and a connecting portion 240 . The connecting portion 240 may be connected to the body 10 , and the extending portion 230 may extend out of the body 10 and be used to connect to the power device 2 and / or the processing unit 3 .

[0044] The embodiment of the present application does not limit the specific structure and form of the connecting portion 240 and the extending portion 230. For example, in one embodiment, along the first direction, the cross-sectional dimension of the extending portion 230 is greater than the cross-sectional dimension of the connecting portion 240. It is understandable that since the extending portion 230 needs to be connected to the power device 2 and / or the processing unit 3, and the connecting portion 240 only needs to be connected to the body 10, the load on the extending portion 230 is greater than that on the connecting portion 240. Therefore, increasing the cross-sectional dimension of the extending portion 230 can make the extending portion 230 have a stronger load-bearing capacity, avoiding or reducing the possibility of the first connecting member 20 being damaged.

[0045] Furthermore, in the present embodiment, the first connecting member 20 may be provided with a waist-shaped hole 231 and an equipment hole 50, wherein the waist-shaped hole 231 is used to connect the power device 2, and the equipment hole 50 is used to connect the processing unit 3. In the present embodiment, the structure for connecting the driving arm 1 with the external equipment is arranged on the first connecting member 20, which can further facilitate the maintenance personnel to disassemble the driving arm 1, the power device 2 and the processing unit 3, thereby facilitating the maintenance personnel to quickly complete the replacement of damaged components.

[0046] It should be noted that the embodiment of the present application does not limit the specific forms of the waist-shaped hole 231 and the device hole 50. For example, in one embodiment, the waist-shaped hole 231 can be set to be inclined compared to the first direction, so that it is convenient for the power device 2 to drive the driving arm 1 to move up and down. The setting method of the waist-shaped hole 231 can be set according to the setting position of the power device 2, and no limitation is made here.

[0047] The device hole 50 can be set as a circular hole, and the circular hole can adapt to more processing units 3. It can be understood that in some other embodiments, the shape of the device hole 50 can be adapted according to the actually connected processing unit 3.

[0048] Furthermore, in the present embodiment, the first connecting member 20 may be provided with a flange structure 210. When the first connecting member 20 is installed on the main body 10, the flange structure 210 may abut against the third surface 130. This may facilitate the user to pre-position the first connecting member 20 and the main body 10. For example, when the user needs to install the first connecting member 20 on the main body 10, the flange structure 210 may be contacted with the third surface 130 first, and then the first connecting member 20 may be pushed toward the main body 10 so that the protrusion is embedded in the card hole. Finally, screws may be screwed into the screw holes of the main body 10 and the first connecting member 20 to complete the installation between the first connecting member 20 and the main body 10.

[0049] Please also see Figure 1 , Figure 2 , Figure 6 and Figure 7In one embodiment, the driving arm 1 may further include a second connecting member 30, and the second connecting member 30 may also be used to connect the power device 2 and / or the processing unit 3. For example, in one embodiment, the second connecting member 30 may be connected to the power device 2 and / or the processing unit 3 together with the first connecting member 20, so that the stability of the connection between the driving arm 1 and the power device 2 and / or the processing unit 3 can be improved. At the same time, the first connecting member 20 and the second connecting member 30 are used to bear the load together, which can reduce the load size of each of the first connecting member 20 and the second connecting member 30, thereby facilitating the improvement of the service life of the first connecting member 20 and the second connecting member 30.

[0050] The second connector 30 may be disposed on the body 10 and extend out of the body 10, and the second connector 30 may be disposed opposite to the first connector 20. The embodiment of the present application does not limit the specific connection method between the body 10 and the second connector 30. For example, in one embodiment, the second connector 30 may be integrally formed with the body 10, which is conducive to improving the overall structural strength and stability of the body 10 and the second connector 30. For example, in another embodiment, the second connector 30 may be detachably disposed with the body 10, and the specific detachable method may refer to the detachable method between the first connector 20 and the body 10, which will not be described in detail here.

[0051] In addition, when the second connecting member 30 and the main body 10 are configured to be detachably connected, the structure of the second connecting member 30 can be consistent with the structure of the first connecting member 20, and a corresponding structure for connection is also provided on the main body 10, which can facilitate the mold production of the first connecting member 20 and the second connecting member 30.

[0052] For example, in this embodiment, the second connecting member 30 can be used as a backup element for the first connecting member 20, that is, the second connecting member 30 is not connected to the power device 2 and / or the processing unit 3. Although the first connecting member 20 is less likely to be damaged during the normal operation of the driving arm 1, the first connecting member 20 is still likely to be damaged. Therefore, when the first connecting member 20 is damaged, the maintenance personnel can directly remove the first connecting member 20 and replace it with the second connecting member 30 during the maintenance process. If the maintenance personnel find that the first connecting member 20 is damaged, the maintenance personnel can greatly shorten the entire maintenance time.

[0053] In this embodiment, there is a gap 40 between the first connecting member 20 and the second connecting member 30, and the third surface 130 is located in the gap 40. The gap 40 can be used to accommodate external equipment, for example, it can be used to accommodate the power device 2 and / or the processing unit 3, etc., so that the structural layout between the driving arm 1 and the external equipment can be more compact and the occupied space can be reduced.

[0054] In summary, the driving arm 1 provided in the embodiment of the present application realizes the rapid disassembly between the driving arm 1 and the power device 2 by setting the driving arm 1 as a detachable structure. Specifically, the driving arm 1 is set in a form in which the main body 10 and the first connecting member 20 are detachably connected. The first connecting member 20 can be used to connect the power device 2. Therefore, in the process of replacing the power device 2, only the first connecting member 20 and the power device 2 can be disassembled. At the same time, the first connecting member 20 is provided with a flange structure 210. In the process of connecting the first mounting member to the driving arm 1, the flange structure 210 can be used for positioning, thereby making the operation of the first connecting member 20 installed on the main body 10 more convenient, solving the technical problem of the cumbersome installation and disassembly process of the power device 2 and the driving arm 1 in the prior art.

[0055] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0056] In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in a reverse order according to the functions involved. For example, the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined.
