Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a flexible clamping mechanism for self-lubricating sliding bearings. Background Technology

[0002] Self-lubricating sliding bearings, as a type of sliding bearing, do not require external oil or grease lubrication. Instead, they achieve low-friction and wear-resistant operation through the inherent properties of the material or a built-in lubrication mechanism. They are widely used in many scenarios, including but not limited to occasions where regular maintenance is difficult, environments with high cleanliness requirements, food machinery, medical equipment, outdoor facilities, and automotive parts.

[0003] After the self-lubricating sliding bearing is manufactured, it needs to be transferred from the manufacturing output to the testing site to test its relevant parameters, such as circular runout.

[0004] In current industrial production, the above operations are usually performed manually. Specifically, the inspector manually removes the finished self-lubricating sliding bearing from the output end and places it in the appropriate testing area.

[0005] Therefore, this method of operation is not only labor-intensive, but also time-consuming and labor-intensive. Furthermore, because self-lubricating sliding bearings are prone to impacts or falling during movement, they may be damaged during the inspection process. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a flexible clamping mechanism for self-lubricating sliding bearings that avoids damage to the self-lubricating material while stably clamping the self-lubricating bearing.

[0007] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0008] A flexible clamping mechanism for self-lubricating sliding bearings includes a bracket for fixing to a robotic arm, characterized in that it further includes a first clamping plate, a second clamping plate, a driving component, and a connecting rod assembly.

[0009] The first clamping plate is flat, and the second clamping plate is also flat with a connecting section protruding to its side at its inner end. The inner end of the first clamping plate is hinged to the bracket, and the inner end of the second clamping plate is hinged to the outer end of the first clamping plate. The two ends of the driving member are respectively hinged to the bracket and the outer end of the connecting section. The two ends of the connecting rod assembly are respectively movably connected to the middle of the bracket and the connecting section.

[0010] The aforementioned clamping plate one, clamping plate two, driving component and connecting rod assembly form a clamping unit. There are two clamping units, and the two clamping units are symmetrically arranged on both sides of the bracket.

[0011] The inner sides of clamping plates one and two in the clamping unit form contact portions for flexible contact with the self-lubricating sliding bearing, and the contact portions of the two clamping units are arranged facing each other.

[0012] In the above-mentioned flexible clamping mechanism for self-lubricating sliding bearings, the clamping plate is made of a flexible material.

[0013] In the above-mentioned flexible clamping mechanism for self-lubricating sliding bearings, the clamping plate 2 includes a rigid body and a flexible contact plate. The body is in the shape of a long plate, the connecting section is located at the inner end of the body and protrudes from the side of the body, and the contact plate is fixed to the body and covers the outer end and middle of the body.

[0014] In the above-mentioned flexible clamping mechanism for self-lubricating sliding bearings, the clamping plate is made of rubber.

[0015] In the aforementioned flexible clamping mechanism for self-lubricating sliding bearings, the contact plate is made of rubber.

[0016] In the above-described flexible clamping mechanism for self-lubricating sliding bearings, the body has a positioning seat extending from the outer end to the middle, and the contact plate is located at the positioning seat and the two are fixedly connected by fasteners.

[0017] In the aforementioned flexible clamping mechanism for self-lubricating sliding bearings, the driving component is a cylinder.

[0018] In the above-mentioned flexible clamping mechanism for self-lubricating sliding bearings, the connecting rod assembly includes connecting rod one and connecting rod two. The inner end of connecting rod one is hinged to the bracket, the inner end of connecting rod two is hinged to the outer end of connecting rod one, and the outer end of connecting rod two is hinged to the middle of the connecting section. The total length of connecting rod one and connecting rod two is greater than the length of clamping plate one.

[0019] In the above-mentioned flexible clamping mechanism for self-lubricating sliding bearings, the hinge joint between the connecting rod and the bracket and the hinge joint between the clamping plate and the bracket coincide.

[0020] In the above-mentioned flexible clamping mechanism for self-lubricating sliding bearings, the length of the first connecting rod is smaller than that of the second connecting rod, and there are two first connecting rods. The inner end of the second connecting rod is hinged between the outer ends of two adjacent first connecting rods.

[0021] Compared to existing technologies, this flexible clamping mechanism for self-lubricating sliding bearings features a flexible contact area formed by clamping plates one and two. Driven by the driving component, this contact area can swing. Simultaneously, the linkage assembly ensures sufficient strength in the contact area, guaranteeing the stable clamping of the self-lubricating sliding bearing between the two clamping units. Compared to manual handling of the self-lubricating sliding bearing, this clamping mechanism, with its stable clamping performance, effectively ensures not only stable transfer of the self-lubricating sliding bearing between processes but also effectively prevents the bearing from falling off during transfer, thus effectively preventing bearing damage.

[0022] In addition, the connecting rod assembly and the drive component are both located on the outer side of the clamping plate, which allows the connecting rod assembly and the drive component to avoid contact interference with the self-lubricating sliding bearing, further improving its stability, while also ensuring the structural compactness of the entire mechanism.

[0028] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0029] like Figure 1-3 As shown, the flexible clamping mechanism for self-lubricating sliding bearings includes a bracket 1 for fixing to a robotic arm, as well as clamping plate 2, clamping plate 3, a drive component 4, and a linkage assembly.

[0030] The first clamping plate 2 is flat, and the second clamping plate 3 is also flat with a connecting section 32 protruding to its side at its inner end. The inner end of the first clamping plate 2 is hinged to the bracket 1, and the inner end of the second clamping plate 3 is hinged to the outer end of the first clamping plate 2. The two ends of the driving member 4 are respectively hinged to the bracket 1 and the outer end of the connecting section 32. The two ends of the connecting rod assembly are respectively movably connected to the middle of the bracket 1 and the connecting section 32.

[0031] The aforementioned clamping plate 1 2, clamping plate 2 3, driving component 4 and connecting rod assembly form a clamping unit. There are two clamping units, and the two clamping units are symmetrically arranged on both sides of the bracket 1.

[0032] The inner sides of clamping plates 2 and 3 in the clamping unit form contact portions for flexible contact with the self-lubricating sliding bearing, and the contact portions of the two clamping units are arranged facing each other.

[0033] The clamp 2 is made of flexible material.

[0034] The clamping plate 3 includes a rigid body 31 and a flexible contact plate 33. The body 31 is in the shape of a long plate. The connecting section 32 is located at the inner end of the body 31 and protrudes from the side of the body 31. The contact plate 33 is fixed to the body 31 and covers the outer end and middle of the body 31.

[0035] Two clamping units are respectively located on both sides of the bracket 1, and each clamping unit has its own independent drive component.

[0036] Therefore, after the two driving components 4 operate synchronously, the contact parts of the two clamping units can move closer or further apart, thereby achieving the clamping and unloading of the self-lubricating sliding bearing.

[0037] Specifically, in the initial state, clamping plates 2 and 3 tend to be close to the edge of the support. At this time, under the action of the corresponding robotic arm, the clamping mechanism can smoothly enter the self-lubricating sliding bearing.

[0038] After the driving component 4 pushes the second clamping plate 3, both the first clamping plate 2 and the second clamping plate 3 move closer to the middle of the bracket 1, so that the contact part formed by the first clamping plate 2 and the second clamping plate 3 is stably pressed against the side wall of the self-lubricating sliding bearing.

[0039] Since clamping plates 2 and 3 need to form flexible contact with the self-lubricating sliding bearing, they are primarily made of flexible materials. The connecting rod assembly located at clamping plate 2 is a rigid rod-shaped structure. Therefore, the connecting rod assembly effectively ensures that the clamping unit has sufficient flexibility while also possessing appropriate strength.

[0040] Conversely, when the gripped self-lubricating sliding bearing enters other processes, such as in an inspection setting, the drive unit 4 reverses its movement, and the self-lubricating bearing smoothly disengages from this clamping mechanism.

[0041] The clamp 2 is made of rubber.

[0042] The contact plate 33 is made of rubber.

[0043] The rubber clamp 2 and contact plate 33 can prevent damage to the self-lubricating sliding bearing during clamping.

[0044] The body 31 has a positioning seat 311 extending from the outer end to the middle part, and the contact plate 33 is located at the positioning seat 311 and the two are fixed together by fasteners.

[0045] After the contact plate 33 is embedded in the positioning seat 311, the positioning seat 311 and the body can form a preliminary pre-position. Under the action of the fastener, the contact plate 33 and the body 31 can be stably fixed together.

[0046] The drive component 4 is a pneumatic cylinder. However, depending on the actual situation, it is also feasible to use a hydraulic cylinder for the drive component 4.

[0047] The connecting rod assembly includes connecting rod 5 and connecting rod 6. The inner end of connecting rod 5 is hinged to the bracket 1, the inner end of connecting rod 6 is hinged to the outer end of connecting rod 5, and the outer end of connecting rod 6 is hinged to the middle of connecting section 32. The total length of connecting rod 5 and connecting rod 6 is greater than the length of clamping plate 2.

[0048] This structure allows the body 31 to oscillate adaptively when the drive element 4 pushes the outer end of the connecting section 32.

[0049] The combined length of connecting rod 5 and connecting rod 6 is greater than the length of clamping plate 2. This structure ensures that clamping plate 2 has adequate strength. At the same time, the deformation of clamping plate 2 after contacting the self-lubricating sliding bearing can accommodate the swinging of connecting rod 5 and connecting rod 6, preventing the connecting rod assembly from jamming.

[0050] The hinge joint between the connecting rod 5 and the bracket 1 and the hinge joint between the clamp 2 and the bracket 1 coincide.

[0051] The two hinges mentioned above are located at the same point, which simplifies the overall structure.

[0052] The length of the first connecting rod 5 is smaller than the length of the second connecting rod 6. There are two first connecting rods 5. The inner end of the second connecting rod 6 is hinged between the outer ends of two adjacent first connecting rods 5.

[0053] This structure ensures that connecting rod 5 and connecting rod 6 are subjected to balanced forces.

[0054] This flexible clamping mechanism for self-lubricating sliding bearings features a flexible contact area formed by clamping plates one and two. Driven by a driving component, this contact area can swing. Simultaneously, the connecting rod assembly ensures sufficient strength in the contact area, guaranteeing the stable clamping of the self-lubricating sliding bearing between the two clamping units. Compared to manual handling of self-lubricating sliding bearings, this clamping mechanism, with its stable clamping performance, effectively ensures not only stable transfer of the bearing between processes but also prevents it from falling off during transfer, thus effectively preventing bearing damage.

[0055] In addition, the connecting rod assembly and the drive component are both located on the outer side of the clamping plate, which allows the connecting rod assembly and the drive component to avoid contact interference with the self-lubricating sliding bearing, further improving its stability, while also ensuring the structural compactness of the entire mechanism.

[0056] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
